Corporate Information

Star Equity Holdings, Inc. (“Star Equity” or the “Company”) is a diversified holding company with three divisions: Digirad Health, Star Building & Construction, and Star Real Estate & Investments. Star Equity, which was incorporated in Delaware in 1997, was formerly known as Digirad Corporation until it changed its name to Star Equity Holdings, Inc. effective January 1, 2021. For additional details related to the Company’s reportable segments, see Item I. Business – Business Segments and Note 17. Segments within the notes to our accompanying consolidated financial statements. Unless the context requires otherwise, in this report the terms “we,” “us,” and, “our” refer to Star Equity and our wholly owned subsidiaries.

ITEM 1.     BUSINESS

Overview

Star Equity, formerly Digirad Corporation, is a diversified, multi-industry holding company which currently operates in two important sectors of the U.S. economy, healthcare, and building & construction. Businesses within these divisions have their own experienced management teams, but are 100% controlled by us through wholly-owned subsidiaries, Digirad Health, Inc. and ATRM Holdings, Inc. Over time, we will consider investing in additional operating businesses and potentially entering additional industry sectors. We also maintain a third division, an internally-focused entity, which holds our corporate real estate and investments and is directly managed at the holding company level.

As of December 31, 2020, we operate the Company in four reportable segments in continuing operations: Diagnostic Services, Diagnostic Imaging, Building and Construction, and Real Estate and Investments.

•Digirad Health: provides medical imaging services and also designs, manufactures, services, and distributes diagnostic medical imaging equipment. Star Equity’s direct and indirect subsidiaries included in this division (including Digirad Health, Inc.) are referred to collectively herein as the “Healthcare Subsidiaries.”

•The Diagnostic Services business segment offers imaging services to healthcare providers, primarily cardiology practices, as an alternative to purchasing the equipment or outsourcing the procedure.

•The Diagnostic Imaging business segment develops, sells, and services solid-state mobile gamma imaging cameras to hospitals and physicians.

•Star Building & Construction segment: designs, manufactures, and distributes wood-based products used in residential and commercial construction projects. KBS Builders, Inc. (“KBS”), EdgeBuilder, Inc. (“EdgeBuilder”), and Glenbrook Building Supply, Inc. (“Glenbrook”) are wholly owned subsidiaries of Star Equity and are referred to collectively herein, and together with ATRM Holdings, Inc. (“ATRM”), as the “Construction Subsidiaries” and the “Building & Construction businesses.”

•Our KBS business primarily manufactures modular housing units, mainly for the New England market, at our production facility in South Paris, ME. In 2020, we entered the structural wall panel business at a second modular production facility in Oxford, ME. We are continually evaluating the possibility of opening a second modular line at the Oxford, ME facility as demand for our product increases. Opening and operating a second modular manufacturing facility should become necessary as we continue pursuing larger commercial-scale multi-family projects, in addition to producing single-family homes.

•Our EdgeBuilder and Glenbrook businesses in the Minneapolis-Saint Paul metropolitan area (referred to collectively herein as “EBGL”) together manufacture structural wall panels, permanent wood foundation systems, and other engineered wood products, and supply general contractors with building materials.

1

•Star Real Estate & Investments segment: manages and finances our more significant corporate real estate assets and would hold any potential minority investment positions we might make in the future. Currently, our only revenue-generating activity in this segment is the intercompany monthly rent eliminated during consolidation received from our affiliate, KBS, which leases 3 modular factories from Star Real Estate Holdings USA, Inc. (“SRE”). Star Equity’s direct and indirect subsidiaries included in this division are SRE, 947 Waterford Road, LLC (“947 Waterford”), 300 Park Street, LLC (“300 Park”), 56 Mechanic Falls Road, LLC (“56 Mechanic”) and Loan Star Value Management, LLC (“LSVM”). Star Real Estate & Investments are referred to collectively herein “Real Estate and Investments”.

Strategy

Star Equity

We believe our diversified, multi-industry holding company structure will allow Star Equity management to focus on capital allocation, strategic leadership, merger and acquisition, capital markets transactions, investor relations, management of our real estate & investments, and other public company activities. Our structural plan will free up our operating Chief Executive Officers to manage their respective businesses, look for organic and bolt-on growth opportunities and improve operations with less distraction and administrative burden.

We continue to explore strategic alternatives to improve the market position and profitability of our product offerings in the marketplace, generate additional liquidity, and enhance our valuation. We may pursue our goals through organic growth and through strategic alternatives. Some of these alternatives have included, and could continue to include, selective acquisitions of business segments or entire businesses, divestitures of assets or divisions, or a restructuring of our company.

Operating Businesses

We seek to grow our business by, among other things:

•Organic growth from our core businesses. We believe that we operate in markets and geographies that will allow us to continue to grow our core businesses, allowing us to benefit from our scale and strengths. We plan to focus our efforts on markets in which we already have a presence in order to take advantage of personnel, infrastructure, and brand recognition we have in these areas.

•Introduction of new services. In the Digirad Health division we plan to continue to focus on healthcare solutions related businesses that deliver necessary assets, services and logistics directly to the customer site. We believe that over time we can either purchase or develop new and complementary businesses and take advantage of our customer loyalty and distribution channels. In the Star Building & Construction division, we will consider opportunities to augment our service offering to better serve our customer base. We have done this in the New England market by adding a structural wall panel line. Other areas might include logistics, installation on site, and manufacturing of sub-components or enhancements that create even more complete modules, such as full HVAC installation.

•Acquisition of complementary businesses. We plan to continue to look at complementary businesses that meet our internally developed financially disciplined approach for acquisitions to grow our company. We believe there are many potential small targets that can be acquired over time and integrated into our platform. We will also look at larger, more transformational acquisitions (public or private) if we believe the appropriate mix of value, risk and return is present for our shareholders. The timing of these potential acquisitions will always depend on market conditions, available capital, and the value for each transaction. In general, we want to be “value” buyers, and will not pursue any transaction unless we believe the post-transaction potential value is high for shareholders.

We continue to explore strategic alternatives to improve the market position and profitability of our product offerings in the marketplace, generate additional liquidity, and enhance our valuation. We may pursue our goals through organic growth and through strategic alternatives. Some of these alternatives have included, and could continue to include, selective acquisitions of business segments or entire businesses, divestitures of assets or divisions, or a restructuring of our company.

Star Real Estate & Investments

The Star Real Estate & Investments business is currently an internally-focused division, also referred to internally as SRE, that is directly managed by Star Equity management. SRE directly owns our three manufacturing facilities in Maine, which are leased to KBS. We have financed these facilities in order to generate proceeds to be used for working capital purposes at our Construction Subsidiaries.

2

Business Segments

As of December 31, 2020, our three divisions are organized into four reportable segments as it relates to continuing operations. These include: Diagnostic Services and Diagnostic Imaging, which together constitute our health care business, known as Digirad Health, and our two newer segments, Building & Construction, and Real Estate & Investments. See Note 17. Segments, within the notes to our accompanying consolidated financial statements for financial data relating to our segments.

For discussion purposes, we categorized our Diagnostic Imaging, and Diagnostic Services reportable segments as “Healthcare”. For the last two fiscal years, Healthcare had the following relative contribution to consolidated revenues:

	Year ended December 31,
	2020		2019
Healthcare Revenues:
Diagnostic Services	50.3	%	65.5	%
Diagnostic Imaging	12.7	%	19.0	%

Real estate and investments revenue is summarized as follows:

	Year ended December 31,
	2020		2019
Real Estate and Investments	0.1	%	0.1	%
Total Real Estate and Investments	0.1	%	0.1	%

Detailed Description of Our Operating Segments

Digirad Health

Diagnostic imaging depictions of the internal anatomy or physiology are generated primarily through non-invasive means. Diagnostic imaging facilitates the early diagnosis of diseases and disorders, often minimizing the scope, cost, and amount of care required and reducing the need for more invasive procedures. Currently, the major types of non-invasive diagnostic imaging technologies available are: x-ray, MRI, CT, ultrasound, PET, and nuclear imaging. The most widely used imaging acquisition technology utilizing gamma cameras is single photon emission computed tomography, or SPECT. Our current internally-developed cardiac gamma cameras employ SPECT technology. Digirad Health is comprised of two segments that specialize in delivering SPECT in a unique and effective manner in order to deliver convenient healthcare solutions on an AS needed, WHEN needed and WHERE needed basis.

3

Diagnostic Services

Through Diagnostic Services, we offer a convenient and economically efficient imaging services program as an alternative to purchasing equipment or outsourcing the procedures to another physician or imaging center. For physicians who wish to perform nuclear imaging, echocardiography, vascular or general ultrasound tests, we provide imaging systems, qualified personnel, radiopharmaceuticals, licensing services, and the logistics required to perform imaging in their own offices, and thereby the ability to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for those services, which are primarily cardiac in nature. We provide imaging services primarily to cardiologists, internal medicine physicians, and family practice doctors who typically enter into annual contracts for a set number of days ranging from once per month to five times per week. Many of our physician customers are reliant on reimbursements from Medicare, Medicaid, and third-party insurers. Although reimbursement for procedures provided by our services have been stable during the last several years, any future changes to underlying reimbursements may require modifications to our current business model in order for us to maintain a viable economic model.

Our portable nuclear and ultrasound imaging operations utilize a “hub and spoke” model in which centrally located regional hubs anchor multiple van routes in the surrounding metropolitan areas. At these hubs, clinical personnel load the equipment, radiopharmaceuticals, and other supplies onto specially equipped vans for transport to customer locations, where they set up the equipment for the day. After quality assurance testing, a technologist under the physician’s supervision will gather patient information, inject the patient with a radiopharmaceutical, and then acquire images for interpretation by the physician. At the conclusion of the day of service, all equipment and supplies are removed from the customer location and transported back to the central hub location. Our model relies on density and customer concentration to allow for efficiencies and maximum profitability, and therefore we are only located in geographies where there is a high concentration of people, cardiac disease and associated likely customer locations.

For our nuclear imaging services, we have obtained Radsite Intersocietal Accreditation Commission (“IAC”) and Intersocietal Commission for Echocardiography Laboratories (“ICAEL”) accreditation for our services. Our licensing infrastructure provides radioactive materials licensing, radiation safety officer services, radiation safety training, monitoring and compliance policies and procedures, and quality assurance functions, to ensure adherence to applicable state and federal nuclear regulations.

Diagnostic Imaging

Through Diagnostic Imaging, we sell our internally developed solid-state gamma cameras, imaging systems and camera maintenance contracts. Our imaging systems include nuclear cardiac imaging systems, as well as general purpose nuclear imaging systems. We sell our imaging systems to physician offices and hospitals primarily in the United States, although we have sold a small number of imaging systems internationally. Our imaging systems are sold in both portable and fixed configurations, provide enhanced operability and improved patient comfort, fit easily into floor spaces as small as seven feet by eight feet, and facilitate the delivery of nuclear medicine procedures in a physician’s office, an outpatient hospital setting, or within multiple departments of a hospital (e.g., emergency and operating rooms). Our Diagnostic Imaging segment revenues derive primarily from selling solid-state gamma cameras and post-warranty camera maintenance contracts.

The central component of a nuclear camera is the detector, which ultimately determines the overall clinical quality of images a camera produces. Our nuclear cameras feature detectors with advanced proprietary solid-state technology developed by us. Solid-state systems have a number of benefits over conventional photomultiplier tube-based camera designs typically offered by our competitors. Our solid-state technology systems are typically 2 to 5 times lighter and considerably more compact than most traditional nuclear systems, making them far easier and less costly to build, very reliable, and able to be utilized for mobile applications. We are a market leader in the mobile solid-state nuclear camera segment.

We believe our current imaging systems, with their state-of-the-art technology and robust underlying patents, will continue to be relevant for the foreseeable future. We will continue to enhance and adjust our existing systems for the changing nuclear imaging market, including software upgrades and smaller enhancements. However, to accomplish any significant changes and enhancements, we will utilize what we believe is a deep available pool of contract engineers on a flexible, as needed basis and do not maintain a fully staffed research and development department.

Star Building & Construction

The building and construction industries lag behind many other manufacturing industry sectors with respect to offsite production. Both modular and prefabricated structural wall panels, produced offsite, are gaining market share in a sector still dominated by more traditional onsite or “stick built” construction.

4

KBS has been in the modular business since 2001 and primarily services the New England market, including Cape Cod and the islands of Martha’s Vineyard and Nantucket, as it is typically not cost-effective to ship modules beyond 300 miles from where they are produced do to their size and weight. We see opportunity for single-family modular homes across our target geography. The opportunity in commercial-scale multi-family modular projects is focused in and around the Boston metropolitan area, although we believe there will be increasing interest in other secondary cities and more densely settled areas. The shortage of affordable housing is a nation-wide challenge and we believe modular construction methods offer a compelling option to help address upfront construction costs, ongoing domestic energy costs, and time-to-market concerns associated with solving this challenge.

EBGL benefits from the same macro drivers towards more factory-built construction. The target market for the structural wall panels it produces is the Minneapolis-Saint Paul area where the need for housing has been growing. EBGL’s panels are sold to builders constructing multi-story, multi-unit structures, including senior living facilities and apartment buildings. Our wood foundations are sold primarily to builders of single family home developments. On the building products distribution side, our showroom and lumber yard focuses on professional builder sales and also provides loose lumber and materials that are bundled with our structural wall panel contracts to streamline the procurement process for these commercial customers. We also supply windows, doors, roofing, decking, drywall, hardware, and other value added products.

EBGL markets its engineered structural wall panels and permanent wood foundation systems through direct sales people and a network of builders, contractors and developers in and around Minneapolis and St. Paul areas. EBGL’s direct sales organization is responsible for both residential and commercial projects and it works with general contractors, developers and builders to provide bids and quotes for specific projects. Our marketing efforts include participation in industry trade shows, production of product literature, and sales support tools. These efforts are designed to generate sales leads for our independent builders and dealers, and direct salespeople.

Our Competitive Strengths

Healthcare Services and Products

Digirad Health delivers convenient, effective, and efficient healthcare solutions on an as needed, when needed, and where needed basis through our mobile products and services. Digirad Health’s diverse portfolio of mobile healthcare solutions and diagnostic imaging equipment and services provides hospitals, physician practices, and imaging centers throughout the United States access to technology and services necessary to provide patient care in the rapidly changing healthcare environment.

We believe that our competitive strengths are our streamlined and cost-efficient approach to providing healthcare solutions to our customers at the point of need, while providing an array of industry-leading, technologically-relevant healthcare imaging and monitoring services:

•Broad Portfolio of Imaging Services. Approximately 50.2% of our revenues are derived from diagnostic imaging services to our customers. We have developed and continue to refine an industry-leading, customer-service focused approach to our customers. We have found our focus in this area is a key factor in acquiring and retaining our service-based customers.

•Unique Dual Sales and Service Offering. For the majority of our businesses, we offer a service-based model to our customers, allowing them to avoid making costly capital and logistical investments required to offer these services internally. Further, for a portion of our business, we have the ability to sell the underlying capital equipment directly to our customers should their needs change and they desire to provide services on their own with the underlying capital equipment. This ability to serve our customers in a variety of capacities from selling equipment directly, or providing more flexibility through a service-based model, allows us to serve our customers according to their exact needs, as well as the ability to capture both ends of the revenue spectrum.

•Utilization of Highly Trained Staff. We recruit and maintain highly trained staff for our clinical and repair services, which in turn allows us to provide superior and more efficient services.

•Leading Solid-State Technology. Our solid-state gamma cameras utilize proprietary photo detector modules that enable us to build smaller and lighter cameras that are portable with a degree of ruggedness that can withstand the vibration associated with transportation. Our dedicated cardiac imagers require a floor space as little as seven feet by eight feet, can generally be installed without facility renovations, and use standard power. Our portable cameras are ideal for mobile operators or practices desiring to service multiple office locations or imaging facilities.

5

Construction Services and Products

Our competitive strengths at KBS include our strategic location with respect to the Greater Boston and broader New England market, the largest manufacturing capacity in the New England region, and an ability to provide high quality wood-based volumetric modules for both single and commercial scale multi-family residential buildings. We also provide significant value through our longstanding engineering and design expertise, with a focus on customization to suit the specific project requirements. We continue to develop our expertise and specialized knowledge in the area of high energy efficient passive homes which includes the delivery of our first zero energy modular (“ZEM”) homes to address the need for affordable housing during 2020. We also added structural wall panels to our product offering in 2020, allowing us to provide an alternative product when modular units are not the right solution. We believe structural wall panels may help facilitate the adoption of offsite construction solutions for some traditional builders who have historically focused on onsite “stick-built” construction.

At EBGL, we also have the ability to offer a superior product for commercial scale multi-family projects. Our engineering and design capabilities allow us to create a product that is unique to the specific project’s requirements. We also provide value with our vertically integrated in-house delivery capability, helping us to be cost-competitive. Our production strategy is to utilize automation and the most efficient methods of manufacturing and high-quality materials in all EBGL projects. Through our building products distribution business we operate a professional lumber yard and showroom and deliver highly personalized service, knowledgeable salespeople, and attention to detail that the larger, big-box chain home stores do not provide.

Sales

Healthcare

We maintain separate sales organizations that are aligned with each of our business units, which operate independently but in cooperation with each other. Diagnostic Services concentrates its efforts on twelve regional areas where the majority of our business is concentrated based on concentrations of people and cardiac disease. Diagnostic Imaging sales efforts are conducted throughout the United States and certain foreign countries, and are not concentrated to any particular region or area within the United States as the customer profile for this business can be at any hospital or physician practice. Diagnostic Services and Diagnostic Imaging, though separate sales teams, work collaboratively to help fulfill customer needs through either small practice mobile nuclear cardiac imaging services, or to provide capital equipment sales should the customer decide to own the equipment in house.

Building & Construction

KBS markets its modular homes products through both outside and inside salespeople. Our inside sales team works primarily with our network of independent dealers who source end customers for single family homes largely in Northern New England. Our outside sales team prospects for single-family residential and commercial multi-unit projects through new and established relationships with architects, designers, developers, owners builders, general contractors, consultants, and construction managers throughout New England. Their work involves developing and negotiating the full scope of work for KBS, terms of payment, and general requirements for each project.

EBGL markets its engineered structural wall panels and permanent wood foundation systems through direct sales people and a network of builders, contractors and developers in the Minneapolis-Saint Paul area and the Upper Midwest states. EBGL’s direct sales organization is responsible for both residential and commercial projects. Our marketing efforts include participation in industry trade shows, production of product literature, and sales support tools. Our showroom and lumber yard services walk-in traffic, mainly professional builders but also homeowner’s, through in house sales clerks.

Competition

Healthcare

The market for diagnostic products and services is highly competitive. Our business, which is focused primarily on the private practice and hospital sectors, continues to face challenges of demand for diagnostic services and imaging equipment, which we believe is due in part to the impact of the Deficit Reduction Act on the reimbursement environment and the 2010 Healthcare Reform laws, as well as general uncertainty in overall healthcare and legislative changes in healthcare, such as the Affordable Care Act. These challenges have impacted, and will likely continue to impact, our operations. We believe that the principal competitive factors in our market include acceptance by hospitals and physicians, relationships that we develop with our customers, budget availability for our capital equipment, requirements for reimbursement, pricing, ease-of-use, reliability, and mobility.

6

Diagnostic Services. In providing diagnostic imaging services, we compete against many smaller local and regional nuclear and ultrasound providers that may have lower operating costs. The fixed-installation operators often utilize older, used equipment, and the mobile operators may use older Digirad single-head cameras or newer dual-head cameras. We are the only mobile provider with our own exclusive source of triple-head mobile systems. Some competing operators place new or used cameras into physician offices and then provide the staffing, supplies, and other support as an alternative to a Diagnostic Services service contract. In addition, we compete against imaging centers that install fixed nuclear gamma cameras and make them available to referring physicians in their geographic vicinity. In these cases, the physician sends their patients to the imaging center.

Diagnostic Imaging. In selling our imaging systems, we compete against several large medical device manufacturers who offer a full line of imaging cameras for each diagnostic imaging technology, including x-ray, MRI, CT, ultrasound, nuclear medicine, or SPECT/CT and PET/CT hybrid imagers. The existing nuclear imaging systems sold by these competitors have been in use for a longer period of time than our internally developed nuclear gamma cameras, and are more widely recognized and used by physicians and hospitals; however, they are generally not solid-state, light-weight, as flexible, or portable. Additionally, certain medical device companies have developed a version of solid-state gamma cameras that may directly compete with our product offerings. Many of the larger multi-modality competitors enjoy significant competitive advantages over us, including greater brand recognition, greater financial and technical resources, established relationships with healthcare professionals, broader distribution networks, more resources for product development and marketing and sales, and the ability to bundle products to offer discounts.

Building & Construction

The market for building and construction is highly competitive.

KBS is a regional manufacturer of modular housing units with its primary market in the New England states. Several modular manufacturers are located in these New England states and in nearby Pennsylvania. Some competitors have manufacturing locations in Canada and ship their products to the United States. KBS’s competitors include Apex Homes, Commodore Corporation, Skyline Champion Homes, Custom Building Systems, Durabuilt, Excel Homes, Huntington Homes, Icon Legacy Homes, Kent Homes (Canada), Maple Leaf Homes (Canada), Muncy Homes, New Era, Pennwest, Premier Builders (PA), Professional Builders Systems, Preferred Building Systems / New England Homes, RCM (Canada), Redmond Homes, Ritz-Craft, Simplex Homes, and Westchester Modular.

EBGL is a regional manufacturer of engineered structural wall panels and permanent wood foundation systems, and also has a local retail business. EBGL’s market is primarily the Upper Midwest states (Iowa, Minnesota, Missouri, North Dakota, South Dakota, and Wisconsin). EBGL’s competitors include Precision Wall Systems, Component Manufacturing Company, JL Schwieters Construction, Arrow Building Center, and Marshall Truss Systems Incorporated. EBGL’s professional building supply business competes on a local level against both small, local lumber yards, regional building supply companies, and to a certain degree, the “big box” stores such as Home Depot, Lowe’s, and Menard’s.

Diagnostic Imaging. We and our contract manufacturers use a wide variety of materials, metals, and mechanical and electrical components for production of our nuclear imaging gamma cameras. These materials are primarily purchased from external suppliers, some of which are single-source suppliers. Materials are purchased from selected suppliers based on quality assurance, cost effectiveness, and constraints resulting from regulatory requirements, and we work closely with our suppliers to assure continuity of supply while maintaining high quality and reliability. Global commodity supply and demand can ultimately affect pricing of certain of these raw materials. Though we believe we have adequate available sources of raw materials, there can be no guarantee that we will be able to access the quantity of raw material needed to sustain operations, as well as at a cost-effective price.

Diagnostic Services. Our Diagnostic Services operations utilize radiopharmaceuticals for our nuclear services. The underlying raw material for creation of the array of doses utilized in nuclear medicine is produced from a total of five main production facilities throughout the world, typically from highly enriched uranium resources. These resources have been and are expected to continue to produce enough raw materials to address the global market, but there continues to be pressure to utilize low or non-enriched uranium resources to produce the underlying nuclear doses.

Building and Construction. Both KBS and EBGL operate in the wood-based building and construction market. The primary raw materials used in their production processes include dimensional lumber, mainly spruce-pine-fir (SPF), and sheathing/sheet goods (OSB and plywood). The majority of underlying raw material for both KBS and EBGL are sourced by wholesalers and mills locally, but we also from time to time source nationally and from Canada. Both businesses depend on the reliability of the lumber supply chain and are sensitive to varying degrees around wood-based commodity price fluctuations.

Manufacturing

Diagnostic Imaging. We manufacture our nuclear imaging gamma cameras by employing a strategy that combines using internal manufacturing resources for devices requiring specific expertise due to our proprietary design coupled with qualified contract manufacturers. Mechanical and electronic components of our systems are produced by contract manufacturers, whereas the most complex components, final assembly and final system performance tests are performed at our facility. All of our suppliers of critical materials, components, and subassemblies undergo supplier qualifications and ongoing quality audits in accordance with our supplier quality process.

We and our contract manufacturers are subject to FDA Quality System Regulations, state regulations, and standards set by the International Organization for Standardization, or ISO. We are currently certified to the EN ISO 13485:2016 quality standard. We have received U.S. Food and Drug Administration (“FDA”) 510(k) clearance for our complete nuclear imaging camera product line (Cardius® XPO, Cardius® X-ACT, and Ergo™ gamma cameras). In addition, the X-ACT camera utilizes an x-ray technology to provide attenuation correction information for the SPECT reconstruction. We also have received additional FDA clearance of our Ergo™ large-field-of-view General Purpose Imager for use in intraoperative and molecular breast imaging.

Building and Construction. KBS began manufacturing single family homes in 2001 and commercial modular multi-family housing units in 2008. In subsequent years, KBS expanded its product offerings to include a variety of commercial buildings including apartments, condominiums, townhouses, dormitories, hospitals, office buildings, and other structures. The structures are built inside our climate-controlled factories and are then transported to the site where they are set, assembled and secured on the foundation. Electrical, plumbing, and HVAC systems are inspected and tested in the factory, prior to transportation to the site, to ensure the modules meet all local building codes and quality requirements. Modular construction has gained increased acceptance and is a preferred method of building by many architects and general contractors. The advantages of modular construction include: modules are constructed in a climate-controlled environment; weather conditions usually do not interrupt or delay construction; the building is protected from weather, reducing the risk of mold due to materials absorbing moisture from rain or snow; reduced site work; improved safety and security; reduced vandalism and attrition, as the building is immediately secured; and a significant reduction in overall project time.

EBGL consists of two separate companies (EdgeBuilder (“EB”) and Glenbrook (“GL”)) operating in tandem with a common management team. EdgeBuilder manufactures wall panels and permanent wood foundations (PWF) in a climate-controlled factory, then transports the panels to the construction site via flat-bed trucks. The panels are typically unloaded by crane and erected or assembled, on site, by professional framing contractors. Panelized construction, especially in large-scale, multi-unit projects, is becoming increasingly popular due to the heightened demand on construction labor. Additionally, because the wall panels are constructed in a controlled indoor environment, waste, weather related delays, and mistakes are minimized. This shaves weeks off large, multi-unit construction schedules, leaving room for more annual builds. Glenbrook fills in all the areas where EdgeBuilder leaves off, with Glenbrook’s vast offerings of professional building products. As International Building Code® continues to evolve, KBS and EBGL, along with our professional partners in the industry, meet code changes with innovative products and a dedicated staff for adherent builds.

Healthcare Reimbursement

All of Digirad Health customers typically rely primarily on the Medicare and Medicaid programs and private payors for reimbursement. As a result, demand for our products and services are dependent in part on the coverage and reimbursement policies of these payors. Third party coverage and reimbursement is subject to extensive federal, state, local, and foreign regulation, and private payor rules and policies. In many instances, the applicable regulations, policies, and rules have not been definitively interpreted by regulatory authorities or the courts, are open to a variety of interpretations, and are subject to change without notice.

The scope of coverage and payment policies vary among third-party private payors. For example, some payors will not reimburse a provider unless the provider has a contract with the payor, and in many instances such payors will not enter into such contracts without the approval of a third party “radiology benefit manager” that the payor compensates based on reducing the payor’s imaging expense. Other payors prohibit reimbursement unless physicians own or lease our cameras on a full-time basis, or meet certain accreditation or privileging standards. Such payor requirements and limitations can significantly restrict the types of business models we can successfully utilize.

Medicare reimbursement rules are subject to annual changes that may affect payment for services that our customers provide. In addition, Congress has passed healthcare reform proposals that are intended to expand the availability of healthcare coverage and reduce the growth in healthcare spending in the U.S. Many of these laws affect the services that our customers provide, and could change further over time.

Medicare reimbursement rules impose many standards and policies on the payment of services that our customers provide. For instance, physicians billing for the technical component of nuclear imaging tests must be accredited by a government-approved independent accreditation body and many private payors are adopting similar requirements. We offer our customers a service to assist them in obtaining and maintaining the required accreditation. We believe we have structured our contracts in a manner that allows our customers to seek reimbursement from third-party payors in compliance with Medicare reimbursement rules. Our physician customers typically bill for both the technical and professional components of the tests. Assuming they meet certain requirements including, but not limited to, performing and documenting bona fide interpretations and providing the requisite supervision of the non-physician personnel performing the tests, they may bill and be paid by Medicare. If the failure to comply is deemed to be “knowing” or “willful,” the government could seek to impose fines or penalties, and we may be required to restructure our agreements and/or respond to any resultant claims by such customers or the government. Our hospital customers typically seek reimbursement by Medicare for outpatient services under the Medicare Hospital Outpatient Prospective Payment System.

Government Regulation

Healthcare

We and our medical professional customers must comply with an array of federal and state laws and regulations. Violations of such laws and regulations can be punishable by criminal, civil, and/or administrative sanctions, including, in some instances, exclusion from participation in healthcare programs such as Medicare and Medicaid. Accordingly, we maintain a vigorous compliance program and a hotline that permits our personnel to report violations anonymously if they wish.

The following is a summary of some of the laws and regulations applicable to our business:

•Anti-Kickback Laws. The Medicare/Medicaid Patient Protection Act of 1987, as amended, which is commonly referred to as the Anti-Kickback Statute, prohibits us from knowingly and willingly offering, paying, soliciting, or receiving any form of remuneration in return for the referral of items or services, or to purchase, lease, order, or arrange for or recommend purchasing, leasing, or ordering any good, facility, service, or item, for which payment may be made under a federal healthcare program. Violation of the federal anti-kickback law is a felony, punishable by criminal fines and imprisonment, or both, and can result in civil penalties and exclusion from participation in healthcare programs such as Medicare and Medicaid. Many states have adopted similar statutes prohibiting payments intended to induce referrals of products or services paid by Medicaid or other nongovernmental third-party payors.

•Physician Self-Referral Laws. Federal regulations commonly referred to as the “Stark Law” prohibit physician referrals of Medicare or Medicaid patients to an entity for certain designated health services if the physician or an immediate family member has an indirect or direct financial relationship with the entity, unless a statutory exception applies. We believe that referrals made by our physician customers are eligible to qualify for the “in-office ancillary services” exception to the Stark Law, provided that the services are provided or supervised by the physician or a member of his or her “Group Practice,” as that term is defined under the law, the services are performed in the same building in which the physician regularly practices medicine, and the services are billed by or for the supervising physician or Group Practice. Violations of the Stark Law may lead to the imposition of penalties and fines, the exclusion from participation in federal healthcare programs, and liability under the federal False Claims Act and its whistleblower provisions. Many states have adopted similar statutes prohibiting self-referral arrangements that cover all patients and not just Medicare and Medicaid patients.

•HIPAA. The Health Insurance Portability and Accountability Act of 1996, or HIPAA, prohibits schemes to defraud healthcare benefit programs and fraudulent conduct in connection with the delivery of, or payment for, healthcare benefits, items, or services. HIPAA also establishes standards governing electronic healthcare transactions and protecting the security and privacy of individually identifiable health information. Some states have also enacted privacy and security statutes or regulations that, in some cases, are more stringent than those issued under HIPAA.

The American Recovery and Reinvestment Act of 2009, enacted February 17, 2009, made significant changes to HIPAA privacy and security regulations. Effective February 17, 2010, we are regulated directly under all of the HIPAA rules protecting the security of electronic individually identifiable health information and many of the rules governing the privacy of such information.

•Medical Device Regulation. The FDA classifies medical devices, such as our cameras, into one of three classes, depending on the degree of risk associated with the device and the extent of control needed to ensure safety and effectiveness. Devices deemed to pose lower risk are placed in either class I or II, which generally requires the manufacturer to submit to the FDA a pre-market notification requesting permission for commercial distribution. This process is known as 510(k) clearance. Devices deemed to pose the greatest risk, such as life-sustaining, life-supporting, or implantable devices, are placed in Class III, requiring an approved Premarket Approval Application (“PMA”). Our cameras are Class II medical devices that have been cleared for marketing by the FDA. We are also subject to post-market regulatory requirements relating to our manufacturing process, marketing and sales activities, product performance, and medical device reports should there be deaths and serious injuries associated with our products.

•Pharmaceutical Regulation. Federal and state agencies, including the FDA and state pharmacy boards, regulate the radiopharmaceuticals used in our Diagnostic Services business.

•Radioactive Materials Laws. We must maintain licensure under, and comply with, federal and state radioactive materials laws, or RAM laws. RAM laws require, among other things, that radioactive materials are used by, or that their use be supervised by, individuals with specified training, expertise, and credentials and include specific provisions applicable to the medical use of radioactive materials.

10

•Environmental Matters. The facilities we operate or manage generate hazardous and medical waste subject to federal and state requirements regarding handling and disposal. We believe that the facilities that we operate and manage are currently in compliance in all material respects with applicable federal, state and local statutes and ordinances regulating the handling and disposal of such materials. We do not believe that we will be required to expend any material additional amounts in order to remain in compliance with these laws and regulations or that compliance will materially affect our capital expenditures, earnings or competitive position.

Employees

As of December 31, 2020, we had a total of 636 full time employees in all our divisions, of which 335 were employed in clinical health-related positions, 127 in manufacturing, 82 in operational roles, 66 in general and administrative functions, and 26 in marketing and sales. All positions are in the United States. We also utilize varying amounts of temporary workers as necessary to fulfill customer requirements. We have not experienced any work stoppages and consider our employee relations to be good.

Recent History of our Business Transformation

On September 10, 2018 we announced that our Board had approved the conversion of the Company into a diversified holding company. We also announced simultaneously that our intent was to make ATRM Holdings, Inc., a building & construction business, our initial “kick-off” transaction.

On December 14, 2018, the Company and ATRM entered into a joint venture and formed Star Procurement, LLC (“Star Procurement”), with the Company and ATRM each holding a 50% interest in Star Procurement. The purpose of the joint venture is to provide the service of purchasing and selling building materials and related goods to KBS with which Star Procurement entered into a Services Agreement on January 2, 2019. In accordance with the terms of the Star Procurement Limited Liability Company Agreement, the Company made a $1.0 million capital contribution to the joint venture in January 2019. This entity was subsequently consolidated within the consolidated financial statements upon completion of the ATRM Merger.

In April 2019, as an initial transaction to create the Company’s real estate division under SRE, the Company funded the initial purchase of three modular building manufacturing facilities in Maine and then leased those three properties to KBS. The initial funding of the acquisition of these assets was primarily through the use of excess borrowing capacity on the credit facility with Sterling National Bank (“Sterling” or “SNB”), a national banking association.

On September 10, 2019 (the “ATRM Acquisition Date”), Star Equity completed its acquisition of ATRM pursuant to an Agreement and Plan of Merger, dated as of July 3, 2019 (the “ATRM Merger Agreement”), among Star Equity, Digirad Acquisition Corporation, a Minnesota corporation and wholly owned subsidiary of Star Equity (“Merger Sub”), and ATRM. Under the terms of the ATRM Merger Agreement, Merger Sub merged with and into ATRM, with ATRM surviving as a wholly owned subsidiary of Star Equity (the “ATRM Merger” or “ATRM Acquisition”). ATRM is now doing business as Star Building & Construction. This “kick-off” transaction marked the official launch of Digirad Corporation, now Star Equity Holdings, Inc., as a diversified, multi-industry holding company.

At the effective time of the ATRM Merger, (i) each share of ATRM common stock was converted into the right to receive three one-hundredths (0.03) of a share of 10.0% Series A Cumulative Perpetual Preferred Stock, par value $0.0001 per share, of the Company (Company Preferred Stock) and (ii) each share of ATRM 10.00% Series B Cumulative Preferred Stock, par value $0.001 per share (ATRM Preferred Stock) converted into the right to receive two and one-half (2.5) shares of Company Preferred Stock, for an approximate aggregate total of 1.6 million shares of Company Preferred Stock. No fractional shares of Company Preferred Stock were issued to any ATRM shareholder in the ATRM Merger. Each ATRM shareholder who would otherwise have been entitled to receive a fraction of a share of Company common stock in the ATRM Merger received one whole share of Company Preferred Stock. Upon the effectiveness of the ATRM Merger, each share of ATRM Common Stock and each share of ATRM Preferred Stock issued and outstanding were no longer be outstanding and automatically were canceled and retired and ceased to exist. ATRM held a special meeting of its shareholders at which the holders of ATRM Common Stock and ATRM Preferred Stock, voting as separate classes, approved the ATRM Merger Agreement and the transactions contemplated thereby, including the ATRM Merger.

11

On October 30, 2020, Star Equity entered into a Stock Purchase Agreement (the “DMS Purchase Agreement”) by and among Star Equity, Project Rendezvous Acquisition Corporation, a Delaware corporation and wholly owned subsidiary of Star Equity (“Seller”), DMS Health Technologies, Inc., a North Dakota corporation and wholly owned subsidiary of Seller (“DMS Health”), and Knob Creek Acquisition Corp., a Tennessee corporation (“Buyer”) pursuant to which, subject to the satisfaction or waiver of certain conditions, Buyer will purchase all of the issued and outstanding common stock of DMS Health, which operates the Mobile Healthcare business, from Seller (the “DMS Sale Transaction”). As a result of the entry into the DMS Purchase Agreement, as of December 31, 2020, the Mobile Healthcare business met the criteria to be classified as held for sale and is reported on the Consolidated Statement of Operations as discontinued operations and on the Consolidated Balance Sheet as Assets and Liabilities held for sale. The purchase price for the DMS Sale Transaction is $18.75 million in cash, subject to certain adjustments, including a working capital adjustment.

On February 1, 2021, the Company completed the sale of its MD Office Solutions subsidiary to M.D.O.S.C.A Inc., a California based holding company (“MDOSCA”), in exchange for a secured promissory note in the original principal amount of $1.4 million and entry into multi-year service and support agreements between MDOSCA and Digirad Health, Inc., a wholly owned subsidiary of the Company.

Restatement of Previously Issued Consolidated Financial Statements

On March 25, 2021, the Board of Directors (the “Board”) of the Company, upon the recommendation of the Audit Committee of the Board and after considering the recommendations of management, and discussing such recommendations with BDO USA, LLP, the Company's independent registered public accounting firm, concluded that our previously released financial statements for quarterly and annual periods after and including March 31, 2019 and any earnings releases or other communications relating to these periods should no longer be relied upon due to misstatements that are described in greater detail in Notes 2 of the Notes to the Consolidated Financial Statements included within this Annual Report on Form 10-K.

Risks Related to Our Business and Industry

Our HoldCo Conversion and related acquisitions or investments could involve unknown risks that could harm our business and adversely affect our financial condition and there can be no assurances that we will be successful as a diversified holding company.

We are a diversified holding company with interests in a variety of industries and market sectors. The real estate acquisitions that we have made under our SRE real estate division and the pending and future acquisitions that we consummate will involve unknown risks, some of which will be particular to the industry in which the acquisition target operates. Although we intend to conduct extensive business, financial, and legal due diligence in connection with the evaluation of all our acquisition and investment opportunities, there can be no assurance our due diligence investigations will identify every matter that could have a material adverse effect on us. We may be unable to adequately address the financial, legal, and operational risks raised by such acquisitions or investments. The realization of any unknown risks could adversely affect our financial condition and liquidity. In addition, our financial condition, results of operations and the ability to service our debt will be subject to the specific risks applicable to any company we acquire or in which we invest.

Part of our strategy as a diversified holding company is to grow through the acquisition of businesses that we believe will realize a material benefit from being part of a larger holding company structure, both financially and strategically. There can be no assurances that we will find suitable acquisition targets that will enable us to successfully realize our conversion into a diversified holding company, and even if such targets are identified, there can be no assurances that we can negotiate and complete such acquisitions on attractive terms. If we succeed in making suitable acquisitions, we may not be able to obtain the expected profitability or other benefits in the short or long term from such acquisitions.

We rely on information technology in our operations, and any material failure, inadequacy, interruption or security failure of that technology could materially harm our business.

We rely on information technology and systems, including the Internet, commercially available software, and other applications, to process, transmit, store, and safeguard information and to manage or support a variety of our business processes, including financial transactions and maintenance of records, which may include personal identifying information and other valuable or confidential information. If we experience material failures, inadequacies, or interruptions or security failures of our information technology, we could incur material costs and losses. Further, third-party vendors could experience similar events with respect to their information technology and systems that impact the products and services they provide to us or to our customers. We rely on commercially available systems, software, tools, and monitoring, as well as other applications and internal procedures and personnel, to provide security for processing, transmitting, storing, and safeguarding confidential information such as personally identifiable information related to our employees and others, information regarding financial accounts, and information regarding customers and vendors. We take various actions, and we incur significant costs, to maintain and protect the operation and security of our information technology and systems, including the data maintained in those systems. However, it is possible that these measures will not prevent the systems’ improper functioning or a compromise in security, such as in the event of a cyberattack or the improper disclosure of information. Security breaches, computer viruses, attacks by hackers, online fraud schemes, and similar breaches can create significant system disruptions, shutdowns, fraudulent transfer of assets, or unauthorized disclosure of confidential information. For example, in April 2019, we became aware that we had been a victim of criminal fraud commonly referred to as “business email compromise fraud.” The incident involved the impersonation of an officer of the Company and improper access to his email, wherein the transfer by the Company of funds to a third-party account almost occurred.

The operation of our healthcare business includes use of complex information technology infrastructures, access to the information technology networks of our customers, as well as the collection of storing of patient information that is subject to HIPAA. In recent years, attacks on corporate information technology infrastructures have become more common and more sophisticated. Any successful attack on our network could severely impact our ability to conduct operations and could result in lost customers. Though we carry customary insurance for notification events in the event of a patient information breach under HIPAA, our coverage may not be sufficient to cover every situation, and any notification could severely impact our customer confidence and operations.

Despite any defensive measures we take to manage threats to our business, our risk and exposure to these matters remain heightened as new and sophisticated methods used by criminals including phishing, social engineering, or other illicit acts, may occur which we may be unable to anticipate or fail to adequately mitigate. Any failure to maintain the security, proper function and availability of our information technology and systems, or certain third-party vendors’ failure to similarly protect their information technology and systems that are relevant to our operations, or to safeguard our business processes, assets, and information could result in financial losses, interrupt our operations, damage our reputation, cause us to be in default of material contracts, and subject us to liability claims or regulatory penalties, any of which could materially and adversely affect us.

15

We may not be able to achieve the anticipated synergies and benefits from business acquisitions.

Part of our business strategy is to acquire businesses that we believe can complement or expand our current business activities, both financially and strategically. On September 10, 2019, we acquired ATRM and its subsidiaries, including KBS, EdgeBuilder and Glenbrook with these synergistic benefits in mind. Acquisitions involve many complexities, including, but not limited to, risks associated with the acquired business’ past activities, loss of customers, regulatory changes that are not anticipated, difficulties in integrating personnel and human resource programs, integrating ERP systems and other infrastructures, general underperformance of the business under our control versus the prior owners, unanticipated expenses and liabilities, and the impact on its internal controls of compliance with the regulatory requirements under the Sarbanes-Oxley Act of 2002. As a result, the realization of anticipated synergies or benefits from acquisitions may be delayed or substantially reduced, and could potentially result in the impairment of our investment in these businesses.

We are subject to particular risks associated with real estate ownership, which could result in unanticipated losses or expenses.

Following our recent acquisition of real estate, our business is subject to many risks that are associated with the ownership of real estate. For example, if our tenants do not renew their leases or default on their leases, we may be unable to re-lease the facilities at favorable rental rates. Other risks that are associated with real estate acquisition and ownership include, without limitation, the following:

•     general liability, property and casualty losses, some of which may be uninsured;

•     the inability to purchase or sell our assets rapidly due to the illiquid nature of real estate and the real estate market;

•     leases which are not renewed or are renewed at lower rental amounts at expiration;

•     the default by a tenant or guarantor under any lease;

•costs relating to maintenance and repair of our facilities and the need to make expenditures due to changes in governmental regulations, such as the Americans with Disabilities Act or remediation of unknown environmental hazards; and

•     acts of God and act of terrorism affecting our properties.

Our revenues may decline due to reductions in Medicare and Medicaid reimbursement rates.

The success of our business is largely dependent upon our medical professional customers’ ability to provide diagnostic care to their patients in an economically sustainable manner, either through the purchase of our imaging systems or using our diagnostic services, or both. Our customers are directly impacted by changes (decreases and increases) in governmental and private payor reimbursements for diagnostic services. We are directly and indirectly impacted by changes in reimbursements. In our businesses, where we are indirectly affected by reimbursement changes, we make every effort to act as business partners with our physician customers. For example, in 2010, we proactively adjusted our diagnostic imaging services rates down due to the dramatic reimbursement declines that our customers experienced from the Centers for Medicare & Medicaid Services. Reimbursements remain a source of concern for our customers and downward pressure on reimbursements causes greater pricing pressure on our services and influences the buying decisions of our customers. Although the gap is closing, hospital reimbursements remain higher than in-office reimbursements. Our Diagnostic Imaging segment’s products are targeted to serve the hospital market. A smaller portion of our Diagnostic Services business segment operates in the hospital market.

Reductions in reimbursements could significantly impact the viability of in-office imaging performed by independent physicians, as well as the viability of our cardiac event monitoring services business. The historical decline in reimbursements in diagnostic imaging has resulted in cancellations of imaging days in our Diagnostic Services business and the delay of purchase and service decisions by our existing and prospective customers in our Diagnostic Imaging business.

16

Our Diagnostic Services revenues may decline due to changes in diagnostic imaging regulations and the use of third party benefit managers by states and private payors to drive down diagnostic imaging volumes.

Nuclear medicine is a “designated health service” under the federal physician self-referral prohibition law known as the “Stark Law,” which states that a physician may not refer designated health services to an entity with which the physician or an immediate family member has a financial relationship, unless a statutory exception applies. Our business model and service agreements are structured to enable our physician customers to meet the statutory in-office ancillary services (“IOAS”) exception to the Stark Law, allowing them to perform nuclear diagnostic imaging services on their patients in the convenience of their own office. From time-to-time, the Centers for Medicare and Medicaid Services and Congress have proposed to modify the IOAS to further limit or eliminate this exception. Various lobbying organizations, including the Medicare Payment Advisory Commission (“MedPAC”), in the past have pushed for, discussed, and recommended that Congress limit the availability of the IOAS exception in order to reduce federal healthcare costs. Legislation has been introduced in prior Congresses to modify or eliminate the exception, but has not been enacted. The outcome of these efforts is uncertain at this time; however, the limitation or elimination of the IOAS exception could significantly impact our Diagnostic Services business segment as currently structured.

Our customers who perform imaging services in their office also experience the continuing efforts by some private insurance companies to reduce healthcare expenditures by hiring radiology benefit managers to help them manage and limit imaging. The federal government has also set aside monies in the 2009 recession recovery acts to hire radiology benefit managers to provide image management services to Medicare/Medicaid and MedPAC has recommended and the Centers for Medicare & Medicaid Services has, in the past, proposed legislation requiring Medicare physicians who engage in a relatively high volume of medical imaging be required to obtain pre-authorization through a radiology benefit manager. A radiology benefit manager is an unregulated entity that performs various functions for private payors and managed care organizations. Radiology benefit manager activities can include pre-authorization for imaging procedures, setting and enforcing standards, approving which contracted physicians can perform the services, such as requiring even the most experienced and highly qualified cardiologists to obtain additional board certifications, or interfering with the financial decision of the private practitioner by requiring them to own their own imaging system and not allowing them to lease the system. The radiology benefit managers often do not provide written documentation of their decisions or an appeals process, leaving leasing physicians unable to challenge their decisions with the carrier or the state insurance department. Unregulated radiology benefit manager activities have and could continue to adversely affect our physician customers’ ability to receive reimbursement, therefore impacting our customers’ decision to utilize our Diagnostic Services imaging services.

Operating results may be adversely affected by changes in the costs and availability of supplies and materials.

Manufacturing and providing service for our nuclear imaging cameras is highly dependent upon the availability of certain suppliers; thereby making us vulnerable to supply problems and price fluctuations that could harm our business. Our manufacturing process within Diagnostic Imaging, and our warranty and post-warranty camera support business, rely on a limited number of third parties to supply certain key components and manufacture our products. Alternative sources of production and supply may not be readily available or may take several months to scale-up and develop effective production processes. If a disruption in the availability of parts or in the operations of our suppliers were to occur, our ability to have gamma cameras built as well as our ability to provide support could be materially adversely affected. In certain cases, we have developed backup plans and have alternative procedures should we experience a disruption. However, if these plans are unsuccessful or if we have a single source, delays in the production and support of our gamma cameras for an extended period of time could cause a loss of revenue and/or higher production and support costs, which could significantly harm our business and results of operations.

Our Diagnostic Services operations are highly dependent upon the availability of certain radiopharmaceuticals, thereby making us vulnerable to supply problems and price fluctuations that could harm our business. Our Diagnostic Service business involves the use of radiopharmaceuticals. There is a limited number of major nuclear reactors supplying medical radiopharmaceuticals worldwide and there is no guarantee that the reactors will remain in good repair or that our supplier will have continuing access to ample supply of our radiopharmaceutical product. If we are unable to obtain an adequate supply of the necessary radiopharmaceuticals, we may be unable to utilize our personnel and equipment through our in-office service operations, or the volume of our services could decline and our business may be adversely affected. Shortages can also cause price increases that may not be accounted for in third party reimbursement rates, thereby causing us to lose margin or require us to pass increases on to our physician customers.

17

Our Building and Construction operating results could be adversely affected by changes in the cost and availability of raw materials. Prices and availability of raw materials used to manufacture its products can change significantly due to fluctuations in supply and demand. Additionally, availability of the raw materials used to manufacture its products may be limited at times resulting in higher prices and/or the need to find alternative suppliers. Both KBS’s and EBGL’s major material components are dimensional lumber and wood sheet products, which include plywood and oriented strand board. Lumber costs are subject to market fluctuations. Furthermore, the cost of raw materials may also be influenced by transportation costs. It is not certain that any price increases can be passed on to its customers without affecting demand or that limited availability of materials will not impact its production capabilities. The state of the financial and housing markets may also impact its suppliers and affect the availability or pricing of materials. ATRM’s inability to raise the price of its products in response to increases in prices of raw materials or to maintain a proper supply of raw materials could have an adverse effect on its revenue and earnings.

Our quarterly and annual financial results are difficult to predict and are likely to fluctuate from period to period.

We have historically experienced seasonality in all of our businesses, volatility due to the changing healthcare environment, the variable supply of radiopharmaceuticals, and downturns based on the changing U.S. economy. While our customers are typically obligated to pay us for imaging days to which they have committed, our contracts permit some flexibility in scheduling when services are to be performed. We cannot predict with certainty the degree to which seasonal circumstances such as the summer slowdown, winter holiday vacations, and weather conditions may affect the results of our operations. We have also experienced fluctuations in demand of our diagnostic imaging product sales due to economic conditions, capital budget availability, and other financial or business reasons, most recently the abrupt increases of quarantine restrictions and reduced demand due to the COVID-19 pandemic. In addition, due to the way that customers in our target markets acquire our products, a large percentage of our products are booked during the last month of each quarterly accounting period, and often there can be a large amount in the last month of the year. As such, a delivery delay of only a few days may significantly impact quarter-to-quarter comparisons of our results of operations. Moreover, the sales cycle for all of our capital products is typically lengthy, particularly in the hospital market, which may cause us to experience significant revenue fluctuations.

We spend considerable time and money complying with federal and state laws, regulations, and other rules which may fluctuate based on healthcare policy, and if we are unable to fully comply with such laws, regulations, and other rules, we could face substantial penalties.

Through our Healthcare businesses we are directly, or indirectly through our customers, subject to extensive regulation by both the federal government and the states in which we conduct our business, including: the federal Medicare and Medicaid anti-kickback laws and other Medicare laws, regulations, rules, manual provisions, and policies that prescribe requirements for coverage and payment for services performed by us and our physician customers; the federal False Claims statutes; the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended in 2009 under the HITECH Act that places direct legal obligations and higher liability on us with respect to the security and handling of personal health information; the Stark Law; the federal Food, Drug and Cosmetic Act; federal and state radioactive materials laws; state food and drug and pharmacy laws and regulations; state laws that prohibit the practice of medicine by non-physicians and fee-splitting arrangements between physicians and non-physicians; state scope-of-practice laws; and federal rules prohibiting the mark-up of diagnostic tests to Medicare under certain circumstances. If our customers are unable or unwilling to comply with these statutes, regulations, rules, and policies, rates of our services and products could decline and our business could be harmed.

Our Building and Construction businesses are subject to various federal, state and local laws and regulations that govern numerous aspects of its business. In recent years, a number of new laws and regulations have been adopted, and there has been expanded enforcement of certain existing laws and regulations by federal, state and local agencies. These laws and regulations, and related interpretations and enforcement activity, may change as a result of a variety of factors, including political, economic or social events. Changes in, expanded enforcement of, or adoption of new federal, state or local laws and regulations governing minimum wage or living wage requirements; the classification of exempt and non-exempt employees; the distinction between employees and contractors; other wage, labor or workplace regulations; healthcare; data protection and cybersecurity; the sale and pricing of some of its products; transportation; logistics; supply chain transparency; taxes; unclaimed property; energy costs and consumption; or environmental matters could increase its costs of doing business or impact its operations.

We maintain a compliance program to identify and correct any compliance issues and remain in compliance with all applicable laws, to train employees, to audit and monitor our operations, and to achieve other compliance goals. Like most companies with compliance programs, we occasionally discover compliance concerns. In such cases, we take responsive action, including corrective measures when necessary. There can be no assurance that our responsive actions will insulate us from liability associated with any detected compliance concerns.

18

If our past or present operations are found to be in violation of any of the laws, regulations, rules, or policies described above or the other laws or regulations to which we or our customers are subject, we may be subject to civil and criminal penalties, damages, fines, exclusion from federal or state healthcare programs, or the curtailment or restructuring of our operations. Similarly, if our physician customers are found to be non-compliant with applicable laws, they may be subject to sanctions that could have a negative impact on us. Any penalties, damages, fines, curtailment, or restructuring of our operations could adversely affect our ability to operate our business and our financial results. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses, divert our management’s attention from the operation of our business, and damage our reputation. Although compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, regulations, rules, and policies, the risks cannot be entirely eliminated. Moreover, achieving and sustaining compliance with applicable federal and state privacy, security, and fraud laws may prove costly.

We are subject to risks associated with self-insurance related to health benefits.

To help control our overall long-term costs associated with employee health benefits, we are self-insured up to certain limits for our health plans. As such, we are subject to risks associated with self-insurance of these health plan benefits. To limit our exposure, we have third party stop-loss insurance coverage for both individual and aggregate claim costs. However, we could still experience unforeseen and potentially significant fluctuations in our healthcare costs based on a higher than expected volume of claims below these stop-loss levels. These fluctuations could have a material adverse effect on our financial position and results of operations.

A portion of our operations are located in a facility that may be at risk from fire, earthquakes, or other disasters.

Final assembly in our manufacturing process and significant portions of our inventory are located in a single facility in Poway, California, near known fire areas and earthquake fault zones. Future natural disasters could cause substantial delays in our operations and cause us to incur additional expenses. Although we have taken precautions to insure our facilities and continuing operations, as well as provide for offsite back-up of our information systems, this may not be adequate to cover our losses in any particular case.

The medical device industry is litigious, which could result in the diversion of our management’s time and efforts, and require us to incur expenses and pay damages that may not be covered by our insurance.

Our operations entail risks of claims or litigation relating to product liability, radioactive contamination, patent infringement, trade secret disclosure, warranty claims, vendor disputes, product recalls, property damage, misdiagnosis, breach of contract, personal injury, and death. Any litigation or claims against us, or claims we bring against others, may cause us to incur substantial costs, could place a significant strain on our financial resources, divert the attention of our management from our core business, and harm our reputation. We may incur significant liability in the event of any such litigation, regardless of the merit of the action. If we are unable to obtain insurance, or if our insurance is inadequate to cover claims, our cash reserves and other assets could be negatively impacted. Additionally, costs associated with maintaining our insurance could become prohibitively expensive, and our ability to become or remain profitable could be diminished.

If we cannot provide quality technical and applications support, we could lose customers and our business and prospects will suffer.

The placement of our products and the introduction of our technology at new customer sites requires the services of highly trained technical support personnel. Hiring technical support personnel is very competitive in our industry due to the limited number of people available with the necessary scientific and technical backgrounds and ability to understand our technology at a technical level. If we are unable to attract, train or retain the number of highly qualified technical services personnel that our business needs, our business and prospects will suffer.

19

Our long-term results depend upon our ability to improve existing products and services and develop, introduce, and market new products and services successfully.

Our business is dependent on the continued improvement of our existing products and services and our development of new products and services utilizing our current or other potential future technology. As we introduce new products and services or refine, improve or upgrade versions of existing products and services, we cannot predict the level of market acceptance or the amount of market share these products and services will achieve, if any. We cannot assure you that we will not experience material delays in the introduction of new products or services in the future.

We generally sell our products and services in industries that are characterized by rapid technological changes, frequent new product introductions and changing industry standards. If we do not develop new products and services and product enhancements based on technological innovation on a timely basis, our products and services may become obsolete over time and our revenues, cash flow, profitability and competitive position may suffer. Even if we successfully innovate and develop new products, services and product enhancements, we may incur substantial costs in doing so, and our profitability may suffer.

We may face risks associated with launching new products and services. If we encounter development or manufacturing challenges or discover errors during our product development cycle, the product launch dates of new products and services may be delayed. The expenses or losses associated with unsuccessful product development or launch activities or lack of market acceptance of our new products and services could adversely affect our business or financial condition.

Our ability to protect our intellectual property and proprietary technology through patents and other means is uncertain.

We rely on patent protection as well as trademark, copyright, trade secret and other intellectual property rights protection and contractual restrictions to protect our proprietary technologies, all of which provide limited protection and may not adequately protect our rights or permit us to gain or keep any competitive advantage. Our success depends, in part, on our ability to protect our proprietary rights to the technologies used in our products. If we fail to protect and/or maintain our intellectual property, third parties may be able to compete more effectively against us, we may lose our technological or competitive advantage, and/or we may incur substantial litigation costs in our attempts to recover or restrict use of our intellectual property.

We do not have any pending patent applications. We cannot assure investors that we will continue to innovate and file new patent applications, or that if filed any future patent applications will result in granted patents. Further, we cannot predict how long it will take for such patents to issue, if at all. It is possible that, for any of our patents that have issued or that may issue in the future, our competitors may design their products around our patented technologies. Further, we cannot assure investors that other parties will not challenge any patents granted to us, or that courts or regulatory agencies will hold our patents to be valid, enforceable, and/or infringed. We cannot guarantee investors that we will be successful in defending challenges made against our patents and patent applications. Any successful third-party challenge or challenges to our patents could result in the unenforceability or invalidity of such patents, or such patents being interpreted narrowly and/or in a manner adverse to our interests. Our ability to establish or maintain a technological or competitive advantage over our competitors and/or market entrants may be diminished because of these uncertainties. For these and other reasons, our intellectual property may not provide us with any competitive advantage.

To the extent our intellectual property offers inadequate protection, or is found to be invalid or unenforceable, we would be exposed to a greater risk of direct or indirect competition. If our intellectual property does not provide adequate coverage of our competitors’ products, our competitive position could be adversely affected, as could our business.

The measures that we use to protect the security of our intellectual property and other proprietary rights may not be adequate, which could result in the loss of legal protection for, and thereby diminish the value of, such intellectual property and other rights or we may need to enter into costly license agreements in the future.

In addition to pursuing patents on our technology, we also rely upon trademarks, trade secrets, copyrights and unfair competition laws, as well as license agreements and other contractual provisions, to protect our intellectual property and other proprietary rights. Despite these measures, any of our intellectual property rights could be challenged, invalidated, circumvented or misappropriated. In addition, we take steps to protect our intellectual property and proprietary technology by entering into confidentiality agreements and intellectual property assignment agreements with our employees, consultants, corporate partners and, when needed, our advisors. Such agreements may not be enforceable or may not provide meaningful protection for our trade secrets and/or other proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements, and we may not be able to prevent such unauthorized disclosure. Moreover, if a party having an agreement with us has an overlapping or conflicting obligation to a third party, our rights in and to certain intellectual property could be undermined. Monitoring unauthorized and inadvertent disclosure is difficult, and we do not know whether the steps we have taken to prevent such disclosure are, or will be, adequate. If we were to enforce a claim that a third party had illegally obtained and was using our trade secrets, it would be expensive and time consuming, the outcome would be unpredictable, and any remedy may be inadequate.

20

If we are sued for infringing intellectual property rights of third parties, it would be costly and time consuming, and an unfavorable outcome in that litigation could have a material adverse effect on our business.

Our success also depends on our ability to develop, manufacture, market and sell our products and perform our services without infringing the proprietary rights of third parties. Numerous U.S. issued patents and pending patent applications owned by third parties exist in the fields in which we are developing products and services. As part of a business strategy to impede our successful commercialization and entry into new markets, competitors may allege that our products and/or services infringe their intellectual property rights.

We could incur substantial costs and divert the attention of our management and technical personnel in defending ourselves against claims of infringement made by third parties. Any adverse ruling by a court or administrative body, or perception of an adverse ruling, may have a material adverse impact on our ability to conduct our business and our finances. Moreover, third parties making claims against us may be able to obtain injunctive relief against us, which could block our ability to offer one or more products or services and could result in a substantial award of damages against us. Intellectual property litigation can be very expensive, and we may not have the financial means to defend ourselves.

Because patent applications can take many years to issue, there may be pending applications, some of which are unknown to us, that may result in issued patents upon which our products or proprietary technologies may infringe. Moreover, we may fail to identify issued patents of relevance or incorrectly conclude that an issued patent is invalid or not infringed by our technology or any of our products.

Our issued patents could be found invalid or unenforceable if challenged in court, at the USPTO or other administrative agency, or in other lawsuits which could have a material adverse impact on our business.

Any patents we have obtained or do obtain may be challenged by re-examination or otherwise invalidated or eventually found unenforceable. Both the patent application process and the process of managing patent disputes can be time consuming and expensive. If we were to initiate legal proceedings against a third party to enforce a patent related to one of our products or services, the defendant in such litigation could counterclaim that our patent is invalid and/or unenforceable. Third parties may also raise similar claims before the USPTO even outside the context of litigation. The outcome is unpredictable following legal assertions of invalidity and unenforceability. With respect to the validity question, for example, we cannot be certain that no invalidating prior art existed of which we and the patent examiner were unaware during prosecution. These assertions may also be based on information known to us or the USPTO. If a defendant or third party were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the claims of the challenged patent. Such a loss of patent protection would or could have a material adverse impact on our business.

Competitors may attempt to challenge or invalidate our patents, or may be able to design alternative techniques or devices that avoid infringement of our patents that have issued or that may issue in the future, or develop products with functionalities that are comparable to ours. In the event a competitor infringes upon our patent or other intellectual property rights, litigation to enforce our intellectual property rights or to defend our patents against challenge, even if successful, could be expensive and time consuming and could require significant time and attention from our management. We may not have sufficient resources to enforce our intellectual property rights or to defend our patents against challenges from others.

An adverse result in any such litigation proceedings could put one or more of our patents at risk of being invalidated, being found to be unenforceable, and/or being interpreted narrowly and could impact the validity or enforceability positions of our other patents. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, an adverse outcome in such litigation or proceedings may expose us to loss of our proprietary position, expose us to significant liabilities, or require us to seek licenses that may not be available on commercially acceptable terms, if at all.

We may make financial investments in other businesses that may lose value.

As we look for the best ways to deploy our capital and maximize our returns for our businesses and shareholders, we may make financial investments in other businesses or processes for purposes of enhancing our supply chain, creating financial returns, strategic developments, or other purposes. These investments may be speculative in nature, and there is no guarantee that we will experience a financial return and we may lose our entire principal balance if not successful.

21

We face risks related to health pandemics and other widespread outbreaks of contagious disease, including the novel coronavirus, COVID-19, which could significantly disrupt our operations and impact our financial results.

Our business has been disrupted and could be materially adversely affected beyond 2020 by the recent outbreak of COVID-19. The outbreak and government measures taken in response have also had a significant impact, both direct and indirect, on businesses and commerce. Global health concerns, such as coronavirus, could also result in social, economic, and labor instability in the countries in which we or the third parties with whom we engage operate. The future progression of the outbreak and its effects on our business and operations are uncertain. We cannot presently predict the scope and severity of any potential business shutdowns or disruptions, including downturns in global economies and financial markets that could affect our future operating results. Any adverse impact on our results and financial condition could have a negative impact on our ability to comply with certain financial covenants in certain of our loan agreements (as described further below) and on your investment in our common stock.

Our goodwill and other long-lived assets are subject to potential impairment that could negatively impact our earnings.

A significant portion of our assets consists of goodwill and other long-lived assets, the carrying value of which may be reduced if we determine that those assets are impaired. At December 31, 2020, goodwill and net intangible assets represented $26.4 million, or 29.9% of our total assets. In addition, net property, plant and equipment assets totaled $9.8 million, or 11.1% of our total assets. If actual results differ from the assumptions and estimates used in our goodwill and long-lived asset valuation calculations, we could incur impairment charges, which could negatively impact our earnings.

We review our reporting units for potential goodwill impairment annually or more often if events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In addition, we test the recoverability of long-lived assets if events or circumstances indicate the carrying values may not be recoverable. Recoverability of long-lived assets is measured by comparison of their carrying amounts to future undiscounted cash flows the assets are expected to generate. We conduct impairment testing based on our current business strategy in light of present industry and economic conditions, as well as future expectations. There are numerous risks that may cause the fair value of a reporting unit to fall below its carrying amount and/or the value of long-lived assets to not be recoverable, which could lead to the measurement and recognition of goodwill and/or long-lived asset impairment. These risks include, but are not limited to, significant negative variances between actual and expected financial results, lowered expectations of future financial results, failure to realize anticipated synergies from acquisitions, adverse changes in the business climate, and the loss of key personnel. If we are not able to achieve projected performance levels, future impairments could be possible, which could negatively impact our earnings.

On September 10, 2019, Star Equity completed its acquisition of ATRM pursuant to the ATRM Merger Agreement. The $8.2 million goodwill recognized is attributable primarily to expected synergies and the assembled workforce of ATRM. As of December 31, 2019, there was a subsequent measurement of goodwill that resulted in an adjustment of $3.0 thousand to the recognized amounts of goodwill resulting from the acquisition of ATRM.

We recorded an impairment loss of $0.4 million associated with the impairment assessment of the EBGL reporting unit as of December 31, 2020. No other significant impairment losses on long-lived assets were recognized during the years ended December 31, 2019. See Note 3. Basis of Presentation, Note 6. Merger and Note 9. Goodwill, within the notes to our accompanying consolidated financial statements for further discussion regarding goodwill and long-lived assets.

The pending sale of DMS Health is subject to closing conditions, the failure of any of which (including failure to obtain certain approvals), could result in our inability to consummate the transaction and, consequently, adversely affect our business, financial condition, results of operations or our stock price.

On October 30, 2020, we entered into the DMS Purchase Agreement to sell all of the issued and outstanding common stock of DMS Health. The purchase price for the DMS Sale Transaction is $18.75 million in cash, subject to certain adjustments, including a working capital adjustment. The completion of the DMS Sale Transaction is subject to receipt of certain consents and closing conditions.

We have spent time and money on the pending sale of DMS Health but we may not be able to consummate the transaction if we fail to obtain the necessary consents and approvals or to satisfy other conditions to closing. In addition, we expect to incur transaction costs in connection with the pending sale of DMS Health, whether or not the transaction is completed.

22

Under the terms of the DMS Purchase Agreement, we are subject to certain restrictions on the conduct of DMS Health's business prior to the completion of the pending sale, which restrictions could adversely affect our ability to realize certain business strategies or take advantage of certain business opportunities. In addition, the current trading price of our common stock and the Company Preferred Stock may reflect a market assumption that the sale of DMS Health will be completed. If we are unable to consummate the sale of DMS Health, we may be unable to find another party willing to purchase DMS Health on equally favorable terms or at all. The failure to complete the sale of DMS Health may adversely affect our business, financial condition, results of operations, and our stock price.

If KBS is unable to maintain or establish its relationships with independent dealers and contractors who sell its homes, KBS revenue could decline.

KBS sells residential homes through a network of independent dealers and contractors. As is common in the modular home industry, KBS’s independent dealers may also sell homes produced by competing manufacturers and can cancel their relationships with KBS on short notice. In addition, these dealers may not remain financially solvent, as they are subject to industry, economic, demographic and seasonal trends similar to those faced by KBS. If KBS is not able to maintain good relationships with its dealers and contractors or establish relationships with new solvent dealers or contractors, KBS’s revenue could decline.

Due to the nature of our business, many of our expenses are fixed costs and if there are decreases in demand for products, it may adversely affect operating results.

Many of our expenses, particularly those relating to properties, capital equipment, and certain manufacturing overhead items, are fixed in the short term. Reduced demand for products causes fixed production costs to be allocated across reduced production volumes, which may adversely affect gross margins and profitability.

Due to the nature of the work the Company and its subsidiaries perform, the Company may be subject to significant liability claims and disputes.

The Company and its wholly owned subsidiaries engage in services that can result in substantial injury or damages that may expose the Company to legal proceedings, investigations and disputes. For example, in the ordinary course of its business, the Company may be involved in legal disputes regarding personal injury and wrongful death claims, employee or labor disputes, professional liability claims, and general commercial disputes, as well as other claims. LSVM as an exempt reporting advisor may also be subject to legal proceedings and investigations with the SEC or other regulatory bodies and may have disputes related to its fiduciary duties to the funds or instruments LSVM manages. An unfavorable legal ruling against the Company or its subsidiaries could result in substantial monetary damages. Although the Company has adopted a range of insurance, risk management, safety, and risk avoidance programs designed to reduce potential liabilities, there can be no assurance that such programs will protect the Company fully from all risks and liabilities. If the Company sustains liabilities that exceed its insurance coverage or for which the Company is not insured, it could have a material adverse impact on its results of operations and financial condition.

Risks Related to our Indebtedness

On March 29, 2019, Star Equity and certain of the Healthcare Subsidiaries entered into a Loan and Security Agreement with Sterling (the “SNB Loan Agreement”). The SNB Loan Agreement is a five-year revolving credit facility (maturing in March 2024), which, as amended, has a maximum credit amount of $20 million (the “SNB Credit Facility”). On January 31, 2020, Star Equity and certain of its Investments Subsidiaries entered into a Loan and Security Agreement with Gerber (as amended, the “Star Loan Agreement”), which provides for a credit facility with borrowing availability of up to $2.5 million and matures on January 1, 2025, unless terminated in accordance with the terms therein (the “Star Loan”). On January 31, 2020, Star Equity and certain of its Construction Subsidiaries entered into a Loan and Security Agreement with Gerber (the “EBGL Loan Agreement”), which provides for a credit facility with borrowing availability of up to $3.0 million and matures on January 1, 2022, unless extended or terminated in accordance with the terms therein (the “EBGL Loan”). On January 31, 2020, Glenbrook and EdgeBuilder entered into an Extension and Modification Agreement (the “Modification Agreement”) with Premier Bank (“Premier”) that modified the terms of the loan made by Premier to Glenbrook and EdgeBuilder pursuant to that certain Revolving Credit Loan Agreement, dated June 30, 2017, by and among Glenbrook, EdgeBuilder and Premier (as amended, the “Premier Loan Agreement”). Pursuant to the Modification Agreement, the amount of indebtedness evidenced by the promissory note issued under the Premier Loan Agreement was reduced to $1.0 million. The credit facility under the Loan and Security Agreement, dated February 23, 2016, by and among KBS, ATRM, the Company and Gerber (as amended, the “KBS Loan Agreement”) provides for a revolving credit facility of up to $4.0 million that matures on February 22, 2021, subject to automatic extension for an additional year unless terminated. The SNB Loan Agreement, Star Loan Agreement, EBGL Loan Agreement, the Premier Loan Agreement and the KBS Loan Agreement are individually referred to as the “Company Loan Agreement” and collectively referred to as the “Company Loan Agreements.” See Note 16. Related Party Transactions, within the notes to our accompanying consolidated financial statements for information regarding certain ATRM promissory notes that are outstanding.

Our indebtedness could restrict our operations and make us more vulnerable to adverse economic conditions.

Our indebtedness could have important consequences for us and our stockholders. For example, the SNB Loan Agreement requires a balloon payment at the termination of the facility in March 2024, which payments may require us to dedicate a substantial portion of our cash flow from operations to this future payment if we feel we cannot be successful in our ability to refinance in the future, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, and acquisitions, and for other general corporate purposes. In addition, our indebtedness could:

•increase our vulnerability to adverse economic and competitive pressures in our industry;

•place us at a competitive disadvantage compared to our competitors that have less debt;

•limit our flexibility in planning for, or reacting to, changes in our business and our industry; and

•limit our ability to borrow additional funds on terms that are acceptable to us or at all.

The Company Loan Agreements governing our indebtedness contain restrictive covenants that restrict our operating flexibility and require that we maintain specified financial ratios. If we cannot comply with these covenants, we may be in default under one or more of the Company Loan Agreements.

The Company Loan Agreements governing our indebtedness contain restrictions and limitations on our ability to engage in activities that may be in our long-term best interests. The Company Loan Agreements contain affirmative and negative covenants that limit and restrict, among other things, our ability to:

•incur additional debt;

•sell assets;

•incur liens or other encumbrances;

•make certain restricted payments and investments;

•acquire other businesses; and

•merge or consolidate.

The SNB Loan Agreement limits our ability to pay dividends and to redeem our equity securities if such dividend or redemption would result in our non-compliance with the financial covenants in the SNB Loan Agreement, there is insufficient borrowing availability under the SNB Loan Agreement, or if there is a default or event of default under the SNB Loan Agreement that has occurred and is continuing. In addition, the Company Loan Agreements include explicit restrictions on the payment of dividends and distributions to Star Equity, which could limit the Company’s ability to pay dividends. The Company may, therefore be required to reduce or eliminate its dividends, if any, including on the Company Preferred Stock (if any outstanding), and/or may be unable to redeem shares of the Company Preferred Stock (if any outstanding) until compliance with such financial covenants can be met.

The Company Loan Agreements contain various financial covenants that, going forward, we or our subsidiaries may not have the ability to meet. The Company Loan Agreements also contain various other affirmative and negative covenants regarding, among other things, the performance of our business, capital allocation decisions made by the Company and its subsidiaries, or events beyond our control.

Our failure to comply with our covenants and other obligations under the Company Loan Agreements may result in an event of default thereunder. A default, if not cured or waived, may permit acceleration of our indebtedness. If our indebtedness is accelerated, we cannot be certain that we will have sufficient funds available to pay the accelerated indebtedness (together with accrued interest and fees), or that we will have the ability to refinance the accelerated indebtedness on terms favorable to us or at all. This could have serious consequences to our financial condition, operating results, and business, and could cause us to become insolvent or enter bankruptcy proceedings, and stockholders may lose all or a portion of their investment because of the priority of the claims of our creditors on our assets.

We may not be entitled to forgiveness of loans we received under the Paycheck Protection Program (“PPP”), and our applicable for such loans could in the future be determined to have been impermissible.

During April and May, we received proceeds of $6.7 million from various loans under the PPP of the CARES Act (the “PPP Loans”). The PPP Loans mature in April and May, 2022 and bear annual interest at a rate of 1.0%.

If no forgiveness is granted or if an unsatisfactory SBA audit is completed, then commencing September and October 2021 we will be required to pay the lenders of the PPP Loans equal monthly payments of principal and interest as required to fully amortize by April and May, 2022 any principal amount outstanding on the PPP Loans. Under the CARES Act, loan forgiveness is generally available for the sum of documented payroll costs, covered rent payments, covered mortgage interest and covered utilities during the twenty-four week period beginning on the date the lender makes the first disbursement of the PPP Loan. We will be required to repay any portion of the outstanding principal that is not forgiven, along with accrued interest, and we cannot provide any assurance that we will be eligible for loan forgiveness, or a favorable SBA audit. Although, we have applied for forgiveness equally among all business entities, and were forgiven $2.5 million as of December 2020 and an additional $1.2 million in Q1 2021, no assurance is provided that forgiveness for any additional portion of the PPP Loans will ultimately be forgiven by the U.S. Small Business Administration (“SBA”).

The Company has received full loan forgiveness from the SBA for the DMS Health Note, DMS Imaging Note, KBS Note, EBGL Notes, and Company Note. The Company has sought full forgiveness from the SBA on the DIS Note based on the satisfaction of applicable criteria and guidelines. PPP Loan forgiveness is sought under the belief all entities requesting loan forgiveness have met the stated criteria and guidelines provided by the SBA and terms of the CARES Act; however, no assurance can be provided that forgiveness for any portion of the PPP Loans will be obtained and all PPP loans may remain subject to review by the SBA even after the PPP Loans have been discharged.

In April 2020, the Secretary of the U.S. Department of the Treasury stated that the SBA will perform a full review of any PPP loan over $2.0 million before forgiving the loan. In order to apply for the PPP Loan, we were required to certify, among other things, that the current economic uncertainty made the PPP Loan requests necessary to support our ongoing operations. We made this certification in good faith after analyzing, among other things, the maintenance of our entire workforce, taking into consideration certain limitations associated with the nature of our work in the healthcare business and uncertainty of the industry where healthcare clients resources may be diverted during the COVID-19 pandemic. In considering our position, the Company took into account our need for additional funding to continue operations, and our ability to access alternative forms of capital in the current market environment to offset the effects of the COVID-19 pandemic. Following this analysis, we believe that we satisfied all eligibility criteria for the PPP Loans, and that our receipt of the PPP Loans is consistent with the broad objectives of the PPP of the CARES Act. The certification described above did not contain any objective criteria and is subject to interpretation. If, despite our good-faith belief that given our circumstances we satisfied all eligible requirements for the PPP Loans, we are later determined to have violated any applicable laws or regulations or it is otherwise determined that we were ineligible to receive the PPP Loans, we may be required to repay the PPP Loans in their entirety and/or be subject to additional penalties, which could also result in adverse publicity and damage to reputation. In addition, if these events were to transpire, they could have a material adverse effect on our business, results of operations and financial condition.

Substantially all of our assets (including the assets of our subsidiaries) have been pledged to lenders as security for our indebtedness under the Company Loan Agreements.

The Company Loan Agreements are secured by a first-priority security interest in substantially all of the assets of the Company and its subsidiaries and a pledge of all shares and equity interests of the Company’s subsidiaries. Upon the occurrence and during the continuation of an event of default under any Company Loan Agreement, the applicable lender may, among other things, declare the loans and all other obligations thereunder immediately due and payable and may, in certain instances, increase the interest rate at which loans and obligations bear interest. The exercise by a lender of remedies provided under the applicable Company Loan Agreement in the event of a default thereunder may have a material adverse effect on the liquidity, financial condition and results of operations of the applicable borrowers and/or the Company and could cause such borrowers and/or the Company to become bankrupt or insolvent. The obligations of the Company and various subsidiaries of the Company under the Company Loan Agreements are guaranteed by other subsidiaries of the Company and/or the Company. In the event of any bankruptcy, liquidation, dissolution, reorganization, or similar proceeding against us, the assets that are pledged as collateral securing any unpaid amounts under the applicable Company Loan Agreement must first be used to pay such amounts, as well as any other obligation secured by the pledged assets, in full, before making any distributions to our stockholders. In the event of any of the foregoing, our stockholders could lose all or a part of their investment.

The inability of the Company or any of the Company’s subsidiaries to comply with applicable financial covenants under the Company Loan Agreements could have a material adverse effect on financial condition of the Company.

KBS, as of December 31, 2020 and 2019 and EBGL as of December 31, 2020 were not in compliance with the financial covenants under the KBS Loan Agreement and EBGL loan agreements respectively which required no net annual post-tax loss and certain minimum leverage ratio covenant as of the end of year test dates. We obtained a waiver from Gerber for these events.

If the Company or any of the Company’s subsidiaries fail to comply with any applicable financial covenants under the Company Loan Agreements to which they are a party, or if there is otherwise an event of default under the Company Loan Agreements by a borrower, the borrowers’ obligations thereunder may (subject to any applicable cure periods) become immediately due and payable and the applicable lender(s) may demand the repayment of the credit facilities amount outstanding and any unpaid interest thereon.

If we are unable to generate or borrow sufficient cash to make payments on our indebtedness, our financial condition would be materially harmed, our business could fail, and stockholders may lose all of their investment.

Our ability to make scheduled payments on or to refinance our obligations will depend on our financial and operating performance, which will be affected by economic, financial, competitive, business, and other factors, some of which are beyond our control. We cannot assure you that our business will generate sufficient cash flow from operations to service our indebtedness or to fund our other liquidity needs. If we are unable to meet our debt obligations or fund our other liquidity needs, we may need to restructure or refinance all or a portion of our indebtedness on or before maturity or sell certain of our assets. We cannot assure you that we will be able to restructure or refinance any of our indebtedness on commercially reasonable terms, if at all, which could cause us to default on our debt obligations and impair our liquidity. Any refinancing of our indebtedness could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations.

Increases in interest rates could adversely affect our results from operations and financial condition.

The SNB, Premier and Gerber Loan Agreements allow for amounts borrowed thereunder to be subject to a floating interest rate which may change with market interest rates. An increase in prevailing interest rates would have an effect on the interest rates charged on our variable rate debt, which rise and fall upon changes in interest rates. If prevailing interest rates or other factors result in higher interest rates, the increased interest expense would adversely affect our cash flow and our ability to service our indebtedness.

Risks Related to our Common Stock and our Company Preferred Stock

If we fail to pay dividends on our Company Preferred Stock for six or more consecutive quarters, holders of our Company Preferred Stock will be entitled to elect two additional directors to our board of directors.

To date no dividends have been paid on the Company Preferred Stock and as a result, cumulative dividends will continue to accrue as part of the liquidation value of the Company Preferred Stock. Whenever dividends on any shares of Company Preferred Stock are in arrears for six or more consecutive quarters, then the holders of those shares together with the holders of all other series of preferred stock equal in rank with the Company Preferred Stock upon which like voting rights have been conferred and are exercisable, will be entitled to vote separately as a class for the election of a total of two additional directors to Star Equity’s board of directors. Holders of our common stock will not be entitled to vote no such additional directors.

The market price of our common stock may be volatile, and the value of your investment could decline significantly.

The market prices of our common stock and our Company Preferred Stock have been, and we expect them to continue to be, volatile. The prices at which our common stock and Company Preferred Stock trade depend upon a number of factors, including our historical and anticipated operating results, our financial situation, announcements of new products by us or our competitors, history of timely dividend payments, the annual yield from dividends on the Company Preferred Stock as compared to yields on other financial instruments, our ability or inability to raise the additional capital we may need and the terms on which we raise it, and general market and economic conditions. Some of these factors are beyond our control. Broad market fluctuations may lower the market price of our common stock and Company Preferred Stock and affect the volume of trading in our stock, regardless of our financial condition, results of operations, business, or prospects. It is impossible to assure you that the market price of our shares of common stock and Company Preferred Stock will not fall in the future.

Our common stock has a low trading volume and shares available under our equity compensation plans could affect the trading price of our common stock.

Our common stock historically has had a low trading volume. Any significant sales of our common stock may cause volatility in our stock price. We also have registered shares of common stock that we may issue under our employee benefit plans or from our treasury stock. Accordingly, these shares can be freely sold in the public market upon issuance, subject to restrictions under the securities laws. If any of these stockholders, or other selling stockholders, cause a large number of securities to be sold in the public market without a corresponding demand, the sales could reduce the trading price of our common stock. One or more stockholders holding a significant amount of our common stock might be able to significantly influence matters requiring approval by our stockholders, possibly including the election of directors and the approval of mergers or other business combination transactions.

Payment of dividends on our common stock is prohibited unless we have declared and paid (or set apart for payment) full accumulated dividends on the Company Preferred Stock, which also has a significant liquidation value.

Unless full cumulative dividends on the Company Preferred Stock have been, or contemporaneously are, declared and paid or declared and a sum sufficient for the payment thereof is set apart for payment for all past dividend periods, no dividends (other than a dividend in shares of common stock or other shares of stock ranking junior to the Series A Preferred Stock as to dividends and upon liquidation) can be declared and paid or declared and set apart for payment on our common stock, nor can any shares of common stock be redeemed, purchased or otherwise acquired for any consideration by the Company. To date no dividends have been paid on the Company Preferred Stock and as a result, cumulative dividends will continue to accrue as part of the liquidation value of the Company Preferred Stock, which had a liquidation value of $10.00 per share at issuance. Dividends on the Company Preferred Stock are payable out of amounts legally available therefor at a rate equal to 10.0% per annum per $10.00 of stated liquidation preference per share, or $1.00 per share of Company Preferred Stock per year. Dividends on the Company Preferred Stock are only be payable in cash. As of December 31, 2019 and 2020, there were 1,915,637 shares of Company Preferred Stock Issued and Outstanding.

If Nasdaq delists the Company Preferred Stock from quotation on its exchange, investors’ ability to make transactions in the Company Preferred Stock could be limited. 

In order to continue listing the Company Preferred Stock on the Nasdaq Global Market, the Company must maintain certain financial, distribution and share price levels. We cannot assure you that the Company Preferred Stock will continue to be listed on the Nasdaq Global Market in the future. If our common stock is delisted from the Nasdaq Global Market, the Company Preferred Stock would be required to meet the more stringent initial listing standards of the Nasdaq Global Market for a Primary Equity Security. If the Company is unable to meet these standards and the Company Preferred Stock is delisted from the Nasdaq Global Market, the Company may apply to list the Company Preferred Stock on the Nasdaq Capital Market. If we are also unable to meet the listing standards for the Nasdaq Capital Market, we may apply to quote the Company Preferred Stock on the OTC Marketplace. If the Company is unable to maintain listing for the Company Preferred Stock, the ability to transfer or sell shares of the Company Preferred Stock will be limited and the market value of the Company Preferred Stock will likely be materially adversely affected.

The market for Company Preferred Stock may not provide investors with adequate liquidity. 

The trading market for the Company Preferred Stock may not provide investors with adequate liquidity. Liquidity of the market for the Company Preferred Stock will depend on a number of factors, including prevailing interest rates, the Company’s financial condition and operating results, the number of holders of the Company Preferred Stock, the market for similar securities and the interest of securities dealers in making a market in the Company Preferred Stock. The Company cannot predict the extent to which investor interest in the Company will maintain a trading market in the Company Preferred Stock, or how liquid that market will be. If an active market is not maintained, investors may have difficulty selling shares of the Company Preferred Stock.

The Company Preferred Stock will bear a risk in connection with redemption. 

The Company may voluntarily redeem some or all of the Company Preferred Stock on or after September 10, 2024. Any such redemptions may occur at a time that is unfavorable to holders of the Company Preferred Stock. The Company may have an incentive to redeem the Company Preferred Stock voluntarily if market conditions allow the Company to issue other preferred stock or debt securities at a rate that is lower than the rate on the Company Preferred Stock. Also, upon the occurrence of a Change of Control Triggering Event (as defined in the Certificate of Designations, Rights and Preferences of 10% Series A Cumulative Perpetual Preferred Stock of the Company (the “Certificate of Designations”)), prior to September 10, 2024, the Company may, at its option, redeem the Company Preferred Stock, in whole or in part.

Star Equity may not be able to redeem the Company Preferred Stock upon a Change of Control Triggering Event. 

Upon the occurrence of a Change of Control Triggering Event, unless the Company has exercised its option to redeem the Company Preferred Stock after September 10, 2024, each holder of the Company Preferred Stock will have the right to require the Company to redeem all or any part of such holder’s Company Preferred Stock at a price equal to the liquidation preference of $10.00 per share, plus an amount equal to any accumulated and unpaid dividends up to but excluding the date of payment, but without interest. If the Company experiences a Change of Control Triggering Event, there can be no assurance that the Company would have sufficient financial resources available to satisfy its obligations to redeem the Company Preferred Stock and any indebtedness that may be required to be repaid or repurchased as a result of such event. In addition, Star Equity may be unable to redeem the Company Preferred Stock upon a Change of Control Triggering Event if such redemption would result in our non-compliance with the financial covenants in the Company Loan Agreements. Star Equity’s failure to redeem the Company Preferred Stock could have material adverse consequences for Star Equity and the holders of the Company Preferred Stock.

As a smaller reporting company, we are subject to scaled disclosure requirements that may make it more challenging for investors to analyze our results of operations and financial prospects.

Currently, we are a “smaller reporting company,” as defined by Rule 12b-2 of the Exchange Act. As a “smaller reporting company,” we are able to provide simplified executive compensation disclosures in our filings and have certain other decreased disclosure obligations in our filings with the SEC, including being required to provide only two years of audited financial statements in annual reports. Consequently, it may be more challenging for investors to analyze our results of operations and financial prospects.

Furthermore, we are a non-accelerated filer as defined by Rule 12b-2 of the Exchange Act, and, as such, are not required to provide an auditor attestation of management’s assessment of internal control over financial reporting, which is generally required for SEC reporting companies under Section 404(b) of the Sarbanes-Oxley Act. Because we are not required to, and have not, had our auditor’s provide an attestation of our management’s assessment of internal control over financial reporting, a material weakness in internal controls may remain undetected for a longer period.

28

If we cannot continue to satisfy the Nasdaq Global Market continued listing standards and other Nasdaq rules, our common stock could be delisted, which would harm our business, the trading price of our common stock, our ability to raise additional capital and the liquidity of the market for our common stock.

Our common stock is currently listed on the Nasdaq Global Market. To maintain the listing of our common stock on the Nasdaq Global Market, we are required to meet certain listing requirements, including, among others, either: (i) a minimum closing bid price of $1.00 per share, a market value of publicly held shares (excluding shares held by our executive officers, directors and 10% or more stockholders) of at least $5.0 million and stockholders’ equity of at least $10 million; or (ii) a minimum closing bid price of $1.00 per share, a market value of publicly held shares (excluding shares held by our executive officers, directors and 10% or more stockholders) of at least $15.0 million and total assets of at least $50.0 million and total revenue of at least $50.0 million (in the latest fiscal year or in two of the last three fiscal years).

There is no assurance that we will be able to maintain compliance with the minimum closing price requirement and other listing requirements. In the event that we fail to maintain compliance with Nasdaq listing requirements for 30 consecutive trading days, our common stock may be delisted from the Nasdaq Global Market. If our common stock were to be delisted from Nasdaq and was not eligible for quotation or listing on another market or exchange, trading of our common stock could be conducted only in the over-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheets or the OTC Bulletin Board. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our common stock, and there would likely also be a reduction in our coverage by securities analysts and the news media, which could cause the price of our common stock to decline further.

If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, the price and trading volume of our securities could decline.

The trading market for our securities will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not currently have and may never obtain research coverage by securities and industry analysts. If no or few securities or industry analysts commence coverage of us, the trading price for our securities would be negatively impacted. In the event we obtain securities or industry analyst coverage, if any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, our intellectual property or our stock performance, or if our clinical trials and operating results fail to meet the expectations of analysts, the price of our securities would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause the price or trading volume of our securities to decline.

If we become a personal holding company, our results could be negatively impacted.

We could be subject to a second level of U.S. federal income tax on a portion of our income if we are determined to be a personal holding company (“PHC”) for U.S. federal income tax purposes. A U.S. corporation generally will be classified as a PHC for U.S. federal income tax purposes in a given taxable year if (i) at any time during the last half of such taxable year, five or fewer individuals (without regard to their citizenship or residency and including as individuals for this purpose certain entities such as certain tax-exempt organizations, pension funds and charitable trusts) own or are deemed to own (pursuant to certain constructive ownership rules) more than 50% of the stock of the corporation by value (by reference to all common, preferred and all other classes of stock) (the “Ownership Test”) and (ii) at least 60% of the corporation’s adjusted ordinary gross income, as determined for U.S. federal income tax purposes, for such taxable year consists of PHC income (which includes, among other things, dividends, interest, certain royalties, annuities and, under certain circumstances, rents) (the “Income Test”).

Based on our knowledge, we believe we meet the Ownership Test discussed above. However, based on our present operations and income sources, we believe that we will not meet the Income Test, and as a result we should not be treated as a PHC for the foreseeable future. If we are or were to become a PHC in a given taxable year, we would be subject to an additional PHC tax, currently 20%, on our undistributed PHC income, which generally includes our taxable income (without the benefit of any federal net operating loss carry forward), subject to certain adjustments. We can give no assurance that we will not become a PHC in the future.

29

Holders of the Company Preferred Stock may be unable to use the dividends-received deduction and may not be eligible for the preferential tax rates applicable to “qualified dividend income.” 

Distributions paid to corporate U.S. holders of the Company Preferred Stock may be eligible for the dividends-received deduction, and distributions paid to non-corporate U.S. holders of the Company Preferred Stock may be subject to tax at the preferential tax rates applicable to “qualified dividend income,” if the Company has current or accumulated earnings and profits, as determined for U.S. federal income tax purposes. Additionally, the Company may not have sufficient current earnings and profits during future fiscal years for the distributions on the Company Preferred Stock to qualify as dividends for U.S. federal income tax purposes. If the distributions fail to qualify as dividends, U.S. holders would be unable to use the dividends-received deduction and may not be eligible for the preferential tax rates applicable to “qualified dividend income.” If any distributions on the Company Preferred Stock with respect to any fiscal year are not eligible for the dividends-received deduction or preferential tax rates applicable to “qualified dividend income” because of insufficient current or accumulated earnings and profits, it is possible that the market value of the Company Preferred Stock might decline.

A holder of Company Preferred Stock has extremely limited voting rights. 

The voting rights for a holder of Company Preferred Stock are limited. Our common stock is the only class of securities that carry full voting rights. Voting rights for holders of Company Preferred Stock exist primarily with respect to material and adverse changes in the terms of the Company Preferred Stock and the Company’s failure to pay dividends on the Company Preferred Stock. Other than the limited circumstances described in the Certificate of Designations, and except to the extent required by law, holders of Company Preferred Stock do not have any voting rights.

The Company Preferred Stock is not convertible into common stock, including in the event of a change of control of the Company, and investors will not realize a corresponding upside if the price of our common stock increases. 

The Company Preferred Stock is not convertible into shares of common stock and earns dividends at a fixed rate. Accordingly, an increase in market price of our common stock will not necessarily result in an increase in the market price of the Company Preferred Stock. The market value of the Company Preferred Stock may depend more on dividend and interest rates for other preferred stock, commercial paper and other investment alternatives and the Company’s actual and perceived ability to pay dividends on, to redeem, and, in the event of dissolution, satisfy the liquidation preference with respect to the Company Preferred Stock.

Our cash available for dividends to holders of the Company Preferred Stock may not be sufficient to pay anticipated dividends, nor can we assure you of our ability to make dividends in the future, and we may need to borrow to make such dividends or may not be able to make such dividends at all. 

To remain competitive with alternative investments, the Company’s dividend rate may exceed our cash available for dividends, including cash generated from operations. In the event this happens, we intend to fund the difference out of any excess cash on hand or, if permitted, from borrowings under our revolving credit facilities. If we don’t have sufficient cash available for dividends generated by its assets, or if cash available for dividends decreases in future periods, the market price of the Company Preferred Stock could decrease.

The protective amendment contained in our Restated Certificate of Incorporation, which is intended to help preserve the value of certain income tax assets, primarily tax net operating loss carryforwards (“NOLs”), may have unintended negative effects.

Pursuant to Internal Revenue Code Sections 382 and 383, use of our NOLs may be limited by an “ownership change” as defined under Section 382 of the Internal Revenue Code of 1986, as amended, and the Treasury Regulations thereunder. In order to protect the Company’s significant NOLs, we filed an amendment to the Restated Certificate of Incorporation of the Company (as amended and extended, the “Protective Amendment”) with the Delaware Secretary of State on May 5, 2015. The Protective Amendment was approved by the Company’s stockholders at the Company’s 2015 Annual Meeting of Stockholders held on May 1, 2015.

On April 27, 2018, we filed a Certificate of Amendment to the Company’s Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, which was approved by our stockholders at our 2018 Annual Meeting (the “Extended Protective Amendment”). The Extended Protective Amendment effects a three-year extension to the provisions of the Protective Amendment. The Extended Protective Amendment leaves the Protective Amendment unchanged in all respects, other than to extend the expiration date from May 1, 2018 to May 1, 2021, and to make revisions necessary as a result of the enactment of Public Law 115-97 (commonly referred to as the Tax Cut and Jobs Act) on December 22, 2017.

30

The Protective Amendment is designed to assist the Company in protecting the long-term value of its accumulated NOLs by limiting certain transfers of the Company’s common stock. The Protective Amendment’s transfer restrictions generally restrict any direct or indirect transfers of the common stock if the effect would be to increase the direct or indirect ownership of the common stock by any person from less than 4.99% to 4.99% or more of the common stock, or increase the percentage of the common stock owned directly or indirectly by a person owning or deemed to own 4.99% or more of the common stock. Any direct or indirect transfer attempted in violation of the Protective Amendment will be void as of the date of the prohibited transfer as to the purported transferee.

The Protective Amendment also requires any person attempting to become a holder of 4.99% or more of our common stock to seek the approval of our Board. This may have an unintended “anti-takeover” effect because our Board may be able to prevent any future takeover. Similarly, any limits on the amount of stock that a shareholder may own could have the effect of making it more difficult for shareholders to replace current management. Additionally, because the Protective Amendment may have the effect of restricting a shareholder’s ability to dispose of or acquire our common stock, the liquidity and market value of our common stock might suffer.

Anti-takeover provisions in our organizational documents and Delaware law may prevent or delay removal of current management or a change in control.

Our restated certificate of incorporation and amended and restated bylaws contain provisions that may delay or prevent a change in control, discourage bids at a premium over the market price of our common stock, and adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock. In addition, as a Delaware corporation, we are subject to Delaware law, including Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder unless certain specific requirements are met as set forth in Section 203. These provisions, alone or together, could have the effect of deterring or delaying changes in incumbent management, proxy contests, or changes in control.

Risks Related to Our Material Weakness and Restatements

Material weakness in our internal control over financial reporting could have a significant adverse effect on our business and the price of our common stock.

As a public reporting company, we are subject to the rules and regulations established from time to time by the SEC. These rules and regulations require, among other things, that we have, and periodically evaluate, disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules, regulations and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow decisions regarding required disclosure. Reporting obligations as a public company are likely to continue to burden our financial and management systems, processes and controls, as well as our personnel.

In addition, as a public company, we are required to document and test our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act so that our management can certify as to the effectiveness of our internal control over financial reporting.

In connection with the preparation of our financial statements for 2020, we have identified material weakness in our internal controls over financial reporting relating to ineffectively designed controls over review of contracts for new debt agreements and proper application of GAAP for such agreements. Further, we identified and corrected certain errors as described in Note 2 to the accompanying financial statements, included in Part II, Item 8 of this Form 10-K. We deemed these corrections to be material to the consolidated financial statements for quarterly and annual periods after and including March 31, 2019 and any earnings releases or other communications relating to these periods. As a result, management concluded that our internal controls over financial reporting as of December 31, 2020 were not effective. As described in Part II, Item 9A of this Form 10-K, management is taking steps to remediate the material weakness in our internal controls. There can be no assurance that any measures we take will remediate the material weakness identified, nor can there be any assurance as to how quickly we will be able to remediate the material weakness.

ITEM 2.PROPERTIES

Effective January 1, 2021, we moved our principal executive offices from Suwanee, Georgia to Old Greenwich, Connecticut, where we have been leasing 1,344 square feet of office space since 2019. We lease a 21,300 square foot facility in Poway, California that houses our Diagnostic Imaging operations. Our Diagnostic Services segment leases approximately 28 small hub locations in the various states in which we operate, which primarily house our fleet of cameras and vans. In November 2019, we entered into a lease for 3,065 square feet of office space in Fargo, North Dakota. In April 2019, our Star Real Estate and Investments business acquired three manufacturing facilities in Maine, which it then leased to KBS, who has in turn sublet one of the facilities to a commercial tenant.

We believe that we have adequate space for our anticipated needs and that suitable additional space will be available at commercially reasonable prices as needed.

Market Information

Our common stock and preferred stock are traded on the NASDAQ Global Market under the symbols “STRR” and “STRRP”, respectively.

As of February 22, 2021, there were approximately 170 holders of record of our common stock. We believe that the number of beneficial owners is substantially greater than the number of record holders because a large portion of our common stock is held of record through brokerage firms in “street name.”

(1)On October 31, 2018, our board of directors approved a stock repurchase program that will enable us to repurchase up to 200,000 shares of our common stock from time to time in market or private transactions (the “2018 Buyback Program”). Under the 2018 Buyback Program, we may purchase shares of our common stock through various means, including open market transactions in compliance with Rule 10b-18 under the Exchange Act, privately negotiated transactions, tender offers or any combination thereof. The number of shares repurchased and the timing of repurchases will depend on a number of factors, including, but not limited to, stock price, trading volume and general market conditions, along with our working capital requirements, general business conditions and other factors.

ITEM 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth previously under the caption “Risk Factors.” This Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our audited consolidated financial statements and related notes included elsewhere in this report.

Executive Overview

The year 2020 marked the first full year that Star Equity, known prior to January 1, 2021 as Digirad Corporation, operated as a multi-industry holding company. With the acquisition of ATRM Holdings in September 2019, we added building and construction businesses to what had historically been a healthcare company and thereby transformed the Company into a diversified holding company with operating businesses in two important industry sectors of the economy, healthcare and building & construction.

Our healthcare business, which is operated as Digirad Health, provides products and services in the area of nuclear imaging with a focus on cardiac health. Digirad Health operates across the U.S. The business involves two reporting segments, Diagnostic Services, which offers imaging services to healthcare providers using a fleet of our proprietary solid-state gamma cameras and Diagnostic Imaging, which manufactures, distributes and maintains our proprietary solid-state gamma cameras.

Our Building & Construction business is a single reporting segment and operates as KBS, EdgeBuilder and Glenbrook. KBS is based in Maine and provides modular buildings throughout the New England market. EdgeBuilder and Glenbrook, referred to together as EBGL internally and based in the Minneapolis-Saint Paul area, together provide structural wall panels and other engineered wood-based products, as well as building materials to customers in the Upper Midwest.

Currently, our real estate and investments segment is an internally-focused division, referred to internally as SRE, that is directly managed by Star Equity holding company management. The entity directly owns our three manufacturing facilities in Maine, which are leased to KBS.

Current Market Conditions

The year 2020 proved to be a challenging year for the vast majority of businesses across many sectors of the economy. While the second half of the year offered hope that we will gradually make our way back to pre-COVID levels of business activity, we are still in the initial phases of the vaccine rollout. This presents continued uncertainty, which we believe will decrease as we move through 2021. On the healthcare side, we expect to see imaging volume recover as the pandemic is brought under control. In building & construction, we expect that continued recovery in employment and a strong housing market will underpin the growth we are seeing.

The target market for our healthcare products and services is comprised of cardiologists, internal medicine physicians, family practice physicians, hospitals, IDNs, and federal institutions in the United States that perform or could perform a diagnostic imaging procedure, have a need for cardiac event monitoring, or have interest in purchasing a diagnostic imaging product. During the year ended December 31, 2020, through Diagnostic Services, we provided imaging services to 584 physicians, physician groups, hospitals, IDNs and federal institutions. Our Diagnostic Services businesses currently operate in approximately 25 states. The overriding challenge during 2020 was the drop in imaging volume due to the COVID-19 pandemic. While we provide critical and important imaging services focused in the cardiac area, the risks of exposure led to reduced patient volumes as these tests were deferred or canceled in hopes that the pandemic would abate.

The target market for our building and construction division includes residential home builders, general contractors, owners/developers of commercial buildings, and individual retail customers. While we witnessed a number of municipalities, especially in the Boston area, shutdown construction sites during the early wave of infections and even shutdown our own plant in South Paris, Maine for six weeks in April and May of 2020, housing demand and demand for building materials have increased as the COVID-19 pandemic has led to “nesting” at home, which have been positive factors in the second half of 2020. The challenge has been less on the demand side and more on the supply chain, as wood-based commodities prices, lumber and OSB, have increased rapidly coming out of the first wave of the pandemic in the Spring of 2020 and supply has not kept up with demand. We have seen some supply chain disruption and tightness during the second half of 2020 and that has continued into 2021 as lead times have extended out, but we are still able to operate at normal levels of production. We believe that the high price environment that we are currently experiencing will lead to additional supply coming on line going forward.

Trends and Drivers

The market for diagnostic services and products is highly competitive. Our business, which is focused primarily on the private practice and hospital sectors, continues to face uncertainty in the demand for diagnostic services and imaging equipment, which we believe is due in part to the impact of the Deficit Reduction Act on the reimbursement environment and the 2010 Healthcare Reform laws, COVID-19 pandemic impact, as well as general uncertainty in overall healthcare and legislative changes in healthcare, such as the Affordable Care Act. These challenges have impacted, and will likely continue to impact, our operations. We believe that the principal competitive factors in our market include budget availability for our capital equipment, qualifications for reimbursement, pricing, ease-of-use, reliability, and mobility.

In the area of reimbursements, our market has been negatively affected in the past by lower reimbursements from the Center for Medicare and Medicaid Services (“CMS”) and third-party insurance providers for the codes under which our customers bill for our services, although reimbursements have stabilized in the last several years. We have addressed, and will continue to address, these market pressures by modifying our Diagnostic Services business models, and by assisting our healthcare customers in complying with new regulations and requirements.

In our Star Building & Construction division, we continue to see a greater adoption of offsite or prefab construction in single-family and multi-family residential building projects, our target market. Our modular units and structural wall panels offer builders a number of benefits over traditional onsite or “stick built” construction. These include shorter time to market, higher quality, reduced waste, readily available labor and potential cost savings, among others. 3D BIM software modeling and developments in engineered wood products offers greater design flexibility for higher-end applications. The need for more affordable housing solutions also presents a great opportunity for the continued emergence of factory built housing.

COVID-19 Pandemic

On March 11, 2020, the World Health Organization declared the outbreak of a novel strain of coronavirus, COVID-19, a global pandemic, which continues to spread throughout the United States and around the world. Governmental authorities in the states in which we operate issued social distancing orders, which orders have required businesses in subject jurisdictions to cease non-essential operations at physical locations in those locations, unless exempted, rescinded, or amended. Accordingly, to comply with applicable regulations and to safeguard the health and safety of our employees and customers, we have temporarily modified our business operations.

During the twelve months ended December 31, 2020, we experienced an $12.4 million decrease in the Digirad Health revenue compared to 2019 related to a decrease in our diagnostic services due to the COVID-19 pandemic. The decrease was offset by a $17.6 million increase respectively, in Building and Construction revenue, as compared to the same period of the prior year. As the COVID-19 pandemic affected the results of segments of our business during the twelve months ended December 31, 2020, we took steps to contain the impact of the COVID-19 pandemic on our business.

On April 1, 2020, we announced that in response to the COVID-19 pandemic, Matthew G. Molchan, our then President and Chief Executive Officer, David J. Noble, our Chief Financial Officer and Chief Operating Officer, and Martin B. Shirley, the president of our Diagnostic Imaging Solutions Inc. subsidiary, had each agreed to have their base salaries reduced by 20%. These reductions were effective as of April 6, 2020, and remained in effect until May 15, 2020.

On April 1, 2020, we also announced that in response to the COVID-19 pandemic, we planned to furlough certain employees and that we would institute a 20% salary reduction for most of our salaried employees and reduce the number of working hours of most of our hourly employees by 20%. These reductions, which applied to our Digirad Health division, were effective as of April 6, 2020, and remained in effect until May 15, 2020. Throughout the COVID-19 pandemic, our building and construction division has furloughed employees or reduced employee hours based on fluctuations in demand for our products. In September, 2020, KBS brought back furloughed employees and increased its work force by over 20% to meet the higher manufacturing requirements for two commercial projects as well as the future growth we expect.

This partial disruption, although expected to be temporary, may impact our operations and overall business. The impact of COVID-19 is evolving rapidly and its future effects are uncertain. Given the uncertainty caused by the COVID-19 pandemic, the duration of the disruption and related financial impact cannot be reasonably estimated at this time. As a result of the evolving impact of COVID-19 on the economy, on April 7, 2020, we withdrew our 2020 full-year guidance. At Star Equity, our highest priority remains the safety, health and well-being of our employees, their families and our communities and we remain committed to serving the needs of our customers. The COVID-19 pandemic is a highly fluid situation and it is not currently possible for us to reasonably estimate the impact it may have on our financial and operating results. We will continue to evaluate the impact of the COVID-19 pandemic on our business as we learn more and the impact of COVID-19 on our industry becomes clearer.

Discontinued Operations

On October 30, 2020, we entered into the DMS Purchase Agreement for the DMS Sale Transaction. The purchase price for the DMS Sale Transaction is $18.75 million in cash, subject to certain adjustments, including a working capital adjustment. We deem the contemplated disposition of the Mobile Healthcare business unit to represent a strategic shift that will have a major effect on our operations and financial results. As of December 31, 2020, in accordance with the provisions of FASB authoritative guidance, the Mobile Healthcare business met the criteria to be classified as held for sale. This segment is reported on the Consolidated Statement of Operations as discontinued operations and on the Consolidated Balance Sheet as Assets and Liabilities held for sale.

Prior to December 31, 2020 we operated in five reportable segments, which included three in our healthcare business, known as Digirad Health. These included Diagnostic Services, Diagnostic Imaging, and Mobile Healthcare. We now have two reportable segments in continuing operations for the healthcare business going forward, Diagnostic Service and Diagnostic Imaging. For additional details related to the Company’s reportable segments, see Item I. Business – Business Segments and Note 17. Segments within the notes to our accompanying consolidated financial statements.

Our building & construction segment, called Star Building & Construction, arose upon completion of the ATRM Merger in September of 2019, and 2020 is the first full-year that its operations will be reflected in our financials.

2020 Financial Highlights

As noted above, during the twelve months ended December 31, 2020, we reclassified our Mobile Healthcare segment to assets held for sale and discontinued operations. When held for sale criteria have been met, revenue, expenses, depreciation and amortization of those assets is suspended and the profits and losses are presented on the Consolidated Statements of Operations as discontinued operations. The operating results presented below are segregated between continuing operations and discontinued operations. Results from prior year comparative period have been reclassified to conform with the current year presentation. In addition, we would note that 2020 was the first full year in which we owned the Building & Construction businesses as they were acquired in September 2019 and financials in the prior year were only inclusive of that stub period in 2019.

Revenues for continuing operations were $78.2 million for the year ended December 31, 2020. This is an increase of $5.2 million, or 7.2%, compared to the prior year due to the following:

•The increase was mainly due to $17.6 million revenue generated by the Building and Construction segment and offset by the following reasons.

•Diagnostic Imaging segment revenue decreased $3.9 million, or 28.2%, primarily due to decrease in the number of cameras sold, reflecting COVID-19 impact.

•Diagnostic Services segment revenue decreased $8.5 million, or 17.7%, primarily due to decrease in scanning service performed, reflecting COVID-19 impact.

Gross profit from continuing operations decreased by $3.2 million, or 18.5%, compared to the prior year, mainly due to a $5.2 million decrease in the Diagnostic Imaging and Diagnostic Services segments caused by the COVID-19 pandemic. This was partially offset by a $2.0 million increase in Building and Construction gross profit, as we owned this business for the entire year in 2020. Additionally, we experienced lower health insurance expenses year over year, which was partially offset by higher lease expenses from an increase in sublease revenue and operating leases.

Total operating expenses increased $2.1 million, or 11.1%, for the year ended December 31, 2020 compared to the prior year, primarily due to additional $3.0 million sales, marketing and general and administrative expenses, $1.3 million of amortization expenses and a $0.4 million goodwill impairment from the building and construction segment, which were mainly offset by a $2.3 million savings in merger and acquisition expenses.

Net loss for continuing operations for the year ended December 31, 2020 was $5.3 million, which is an increase of $2.5 million compared to our net loss of $2.7 million during the prior year. This was driven primarily by additional net loss of $2.7 million in the Star Building & Construction division during the year ended December 31, 2020, despite a $0.2 million increase in net income from the Digirad Health division. As a result of the recent acquisition of the Building & Construction businesses, we are experiencing a considerable increase in the amortization of intangibles in our income statement.

For the year ended December 31, 2020, Diagnostic Services operated 90 nuclear gamma cameras and 46 ultrasound imaging systems. We measure efficiency by tracking system utilization, which is based on the percentage of days that our cameras, equipment and imaging systems are used to deliver services to customers out of the total number of days that they are available to deliver such services. System utilization for Diagnostic Services for the year ended December 31, 2020, was 59% compared to 60% of the prior year.

Use of EBITDA (Non-GAAP measure)

Management believes EBITDA is a meaningful indicator of the Company’s performance that provides useful information to investors regarding the Company’s financial condition and results of operations. EBITDA is also considered by management as an indicator of operating performance and the most comparable measure across the regions in which we operate. Management also uses this measurement to evaluate capital needs and working capital requirements. Similar to constant currency, EBITDA is a non-GAAP financial measure that is not intended to be considered in isolation from, as substitute for, or as superior to, the corresponding financial measure prepared in accordance with GAAP or as a measure of the Company’s profitability. Because of these and other limitations, EBITDA should be considered along with GAAP based financial performance measures, including operating income or net income prepared in accordance with GAAP. EBITDA is derived from net (loss) income adjusted for the provision for (benefit from) income taxes, interest expense (income), and depreciation and amortization.

The reconciliation of EBITDA from continuing operations to the most directly comparable GAAP financial measure is provided in the table below:

	Year Ended December 31,

Revenues

Healthcare

Healthcare revenue by segment is summarized as follows (in thousands):

	Year Ended December 31,
	2020		2019		$ Change		% Change
Diagnostic Services	$	39,267	$	47,723	$	(8,456)	(17.7)	%
Diagnostic Imaging	9,965		13,872		(3,907)		(28.2)	%
Total Healthcare Revenue	$	49,232	$	61,595	$	(12,363)	(20.1)	%

The decrease in Diagnostic Services and Diagnostic Imaging revenue was primarily due to the COVID-19 pandemic impact. Although many medical offices and facilities temporarily closed in mid-March, most are now open and many hospitals that stopped performing non-emergency procedures, tests, and scans slowly started to re-open and serve patients during the quarter, although at lower than pre-COVID-19 schedule.

38

Building and Construction

Building and construction revenue is summarized as follows (in thousands):

	Year Ended December 31,
	2020		2019		$ Change		% Change
Building and Construction	$	28,879	$	11,257	$	17,622	156.5	%
Total Building and Construction Revenue	$	28,879	$	11,257	$	17,622	156.5	%

The increase in building and construction revenue was due to our ownership of the business for a full year, compared to one quarter and 20 days prior year same period. Moreover, we experienced an increase in KBS activity levels and recognized $4.3 million of revenue on two large commercial projects, as we re-entered the commercial market in 2020.

Real Estate and Investments

Real estate and investments revenue is summarized as follows (in thousands):

	Year Ended December 31,
	2020		2019		$ Change		% Change
Real Estate and Investments	$	52	$	82	$	(30)	(36.6)	%
Total Real Estate and Investments	$	52	$	82	$	(30)	(36.6)	%

The decrease in real estate and investments revenue was due to the wind down of investment vehicles from LSVM. Intercompany lease revenue from KBS for the three factories we own was eliminated through consolidation in the consolidated financial statements.

Gross Profit

Healthcare

Healthcare gross profit and gross margin is summarized as follows (in thousands):

	Year Ended December 31,
	2020			2019			% Change
Diagnostic Services gross profit	$	6,758		$	10,237		(34.0)	%
Diagnostic Services gross margin	17.2		%	21.5		%
Diagnostic Imaging gross profit	3,391			5,136			(34.0)	%
Diagnostic Imaging gross margin	34.0		%	37.0		%
Total healthcare gross profit	$	10,149		$	15,373		(34.0)	%
Total healthcare gross margin	20.6		%	25.0		%

The decrease in Diagnostic Services and Diagnostic Imaging gross profit is mainly due to the COVID-19 pandemic impact and the associated public health measures in place, which directly reduced scanning revenue and camera sales. While management proactively applied measures to contain costs during the pandemic, there were fixed costs which resulted in the decrease in gross margin.

Star Building & Construction

Star Building & Construction gross profit and margin is summarized as follows (in thousands):

	Year Ended December 31,
	2020			2019			% Change
Building and Construction gross profit	$	4,047		$	2,013		101.0	%
Building and Construction gross margin	14.0		%	17.9		%

39

The increase in building and construction gross profit is mainly due to the fact that 2020 includes a full year of operational data from this segment as compared to a portion of the year in 2019 and increased revenue from KBS’ two large commercial projects. Gross profit of our Star Building & Construction business for Q4 2020 decreased by 12.8%, from prior year same period, due to the negative effect of higher raw material prices.

Star Real Estate & Investments

Star Real Estate & Investments gross profit and margin is summarized as follows (in thousands):

	Year Ended December 31,
	2020			2019			% Change
Real Estate and Investments gross profit	$	(209)		$	(226)		(7.5)	%
Real Estate and Investments gross margin	(401.9)		%	(275.6)		%

Star Real Estate & Investments manages three manufacturing facilities which it leases to KBS and investment vehicles through LSVM. Its negative gross profit relates to depreciation expense and the write-off of some of the assets included with the three manufacturing facilities acquired in April 2019.

Operating Expenses

Operating expense are summarized as follows (in thousands):

	Year Ended December 31,								Percent of Revenues
	2020		2019		$ Change		% Change		2020		2019
Selling, general and administrative	$	18,635	$	15,898	$	2,737	17.2	%	23.8	%	21.8	%
Amortization of intangible assets	2,124		829		1,295		156.2	%	2.7	%	1.1	%
Merger and financing costs	—		2,342		(2,342)		—	%	—	%	3.2	%
Goodwill impairment	436		—		436		—	%	0.6	%	—	%
Total operating expenses	$	21,195	$	19,069	$	2,126	11.1	%	27.1	%	26.1	%

Total operating expenses increased $2.1 million, or 11.1%, for the year ended December 31, 2020 compared to the prior year. The increase was due in part to the additional $3.0 million sales, marketing and general and administrative expenses from the building and construction segment. We also recognized an additional $1.3 million in amortization of intangibles and a $0.4 million write-down of goodwill. Much of the total increase in operating expenses was offset by $2.3 million worth of savings in merger and acquisition expenses. We also experienced a $0.3 million savings in sales and general and administrative expenses in the healthcare segments.

The $1.3 million increase in amortization of intangible assets was primarily due to $19.5 million of additional intangible assets related to the ATRM Acquisition on September 10, 2019.

Goodwill non-cash impairment charges increased by $0.4 million compared to the prior year, primarily as a result of an impairment recorded during the fourth quarter of 2020 in our EBGL reporting unit. See Note 9. Goodwill, within the notes to our accompanying consolidated financial statements for further information.

Other Income (Expense)

Total other income (expense) is summarized as follows (in thousands):

	Year Ended December 31,
	2020		2019
Other income (expense), net	$	3,344	$	(133)
Interest expense, net	(1,292)		(746)
Loss on extinguishment of debt	—		(151)
Total other income (expense)	$	2,052	$	(1,030)

Other income was generated from $2.5 million in partial forgiveness on PPP Loans taken during 2020 (see Note 10. Debt within the notes to our accompanying consolidated financial statements), the settlement of an aged Massachusetts sales and use tax payable at KBS and the settlement of legacy legal costs at ATRM, the immediate parent of our Building & Construction businesses, as well as unrealized gains from equity securities.

40

The increase in interest expense comes from additional acquired debt in the Building & Construction business, despite a significant reduction in interest rates on the substantial portion of our total debt which is based on a floating rate.

The loss on extinguishment of debt for the year ended December 31, 2019, is related to the write-off of unamortized deferred financing costs related to the termination of our prior revolving credit facility with Comerica on March 29, 2019. See Note 10. Debt, within the notes to our accompanying consolidated financial statements for further information regarding interest expense and loss on extinguishment of debt.

Income Tax (Expense) Benefit

Intraperiod allocation rules require us to allocate our provision for income taxes between continuing operations and other categories or comprehensive income (loss) such as discontinued operations. During the twelve months ended December 31, 2020, and 2019, a tax provision of $0.1 million and tax benefit of $0.2 million were recorded in continuing operations, respectively. For the year ended December 31, 2020, the Company recorded a tax expense of $22 thousand to discontinued operations. For the year ended December 31, 2019, the Company recorded a benefit of $0.1 million to discontinued operations. As described in Note 4. Discontinued Operations, the results of our Mobile Healthcare reportable segment have been reported as discontinued operations for the current and prior year.

See Note 14. Income Taxes, within the notes to our accompanying consolidated financial statements for further information.

Loss from Discontinued Operations

As described in Note 4. Discontinued Operations, within the notes to our accompanying consolidated financial statements, the results of our mobile healthcare reportable segment have been reported as discontinued operations for all periods presented.

Liquidity and Capital Resources

Overview

Cash Flows from Operating Activities

For the year ended December 31, 2020, net cash used in operating activities was $5.0 million, as compared to $0.4 million of net cash generated from operating activities in 2019, resulting in an increase in net cash used in operating activities of $5.5 million. The increase in net cash used in operating activities resulted primarily from working capital investments made in our Building & Construction businesses during 2020, principally into KBS, as well as a higher net loss caused by reduced revenues due to the COVID-19 impact on our businesses, particularly on our Digirad Health division.

Cash Flows from Investing Activities

For the year ended December 31, 2020, net cash used in investing activities was $1.3 million, as compared to $5.8 million of net cash used by investing activities in 2019. The $4.5 million decrease in net cash used in investing activities primarily reflects a return to normalized capital expenditure as we had paid $5.2 million in 2019 to acquire the three factories from KBS prior to purchasing the full Building & Construction business later that year when we closed the acquisition of ATRM.

Cash Flows from Financing Activities

For the year ended December 31, 2020, net cash generated from financing activities was $8.1 million, as compared to net cash generated from financing activities of $5.7 million in 2019, resulting in an increase in net cash generated from financing activities of $2.4 million. The increase was attributable to proceeds from the Paycheck Protection Program (“PPP”) loan of $6.7 million in late April and early May and net proceeds from our common stock offering of $5.2 million in late May, partially offset by a $3.2 million net reduction in principal on existing debt.

Cash Flows

Our principal sources of liquidity are our existing cash and cash equivalents, cash generated from operations, and availability on our revolving lines of credit from our credit facility with Sterling National Bank, our three credit facilities with Gerber Finance, Inc and one credit facility with Premier. As of December 31, 2020, we had $3.2 million of cash and cash equivalents, as well as approximately $7.3 million in undrawn capacity on our $20.0 million Sterling National Bank revolving line of credit. The Gerber facilities directly support our Building & Construction businesses. As of December 31, 2020, we were fully drawn in terms of available capacity at $1.1 million on the KBS revolver and $2.0 million on the EBGL revolver. However, those facilities have loan limits of $4.0 million and $3.0 million, respectively, and we expect to be able to use more of that availability as our borrowing base increases with higher production levels.

Liquidity Outlook

We require capital, principally for capital expenditures, acquisition activity, dividend payments and to finance accounts receivable and inventory. Our working capital requirements vary from period to period depending on inventory requirements, the timing of deliveries, and the payment cycles of our customers. Our capital expenditures consist of medical imaging and diagnostic devices utilized in the provision of our services, as well as vehicles and information technology hardware and software. In addition, we are putting in place capital expenditure programs in the Building & Construction business in order to improve operations and expand our production output. Generally, this business is not capital intensive, although we had to augment working capital significantly in 2020, especially at KBS, to support higher production levels.

The accompanying consolidated financial statements have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and settlement of obligations in the normal course of business. We incurred net losses from continuing operations of approximately $7.2 million and $1.9 million for the twelve months ended December 31, 2020 and 2019, respectively. We have an accumulated deficit of $125.0 million and $118.5 million as of December 31, 2020 and 2019, respectively. Net cash used in operations of $5.0 million for the twelve months ended December 31, 2020 compared to net cash provided by operations of $0.4 million for the same prior year period in 2019. The Company will need to secure additional future financing to accomplish its business plan over the next several years and that there can be no assurance on the availability or terms upon which such financing and capital mat be available in the future.

Regarding our debt, GAAP rules require us to classify $18.4 million as short-term debt, as of December 31, 2020. However, $12.7 million of our debt allocation to short-term relates to the balance on our revolving line of credit with Sterling. This debt primarily supports our healthcare business and the SNB Loan Agreement actually matures in 2024, but GAAP rules require that the outstanding balance be classified as short-term debt, due to the automatic sweep feature embedded in the traditional lockbox arrangement along with a subjective acceleration clause in the agreement. In practice, we have the ability to immediately borrow back these daily sweeps to fund our working capital.

An additional $3.1 million of revolver debt supporting our Building & Construction businesses is classified as short-term debt. This includes the $2.0 million and $1.1 million balances on our Gerber revolvers at EBGL and KBS, respectively. These credit facilities each have an automatic annual renewal features. The remaining $2.5 million of our short-term debt includes $1.9 million worth of a PPP loan, which is expected to be forgiven within 2021, as well as $0.6 million representing the current portion of a long-term term loan. Although we were in breach of certain debt covenants on the Building & Construction revolvers, Gerber delivered waivers and we are not in default on this or any other portions of our debt.

Further, the short-term classification of the SNB revolver is a technical GAAP presentation requirement given the traditional lockbox arrangement. The revolver directly supports our healthcare business, but may be drawn to fund non-healthcare operations as long as we maintain a $4 million cushion of excess availability following any non-healthcare distributions. As of December 31, 2020 we had $7.3 million in excess availability on the SNB revolver and were in compliance with all covenants related to this facility, as further discussed in Note 10. Debt, within the notes to our accompanying consolidated financial statements below.

Additional short-term related-party debt is held by Mr. Eberwein, our Executive Chairman, totaling approximately $2.3 million at December 31, 2020. Mr. Eberwein has committed to provide financial support to the Company by providing written assurances that he will (1) extend and not force repayment of this debt, which was due October 2020, until five business days after the closing date of the DMS Sale Transaction, the date when the Note is no longer subject to a certain subordinate letter agreement with Gerber, or to June 30, 2022.; and (2) extend through June 2021 the Company’s put option with him with respect to $1.0 million in Company Preferred Stock. See Note 16. Related Party Transactions, within the notes to our accompanying consolidated financial statements, for information regarding the financial support provided by Mr. Eberwein. We expect to fully payoff this debt from proceeds generated upon the closing of the DMS sale.

Management believes that we have the liquidity and operations to continue to support the business through the next 12 months from the issuance of this Annual Report. Our ability to continue as a going concern is dependent on our ability to execute our plans.

Common Stock Offering

On May 28, 2020, we closed a public offering (the “Offering”) of 2,225,000 shares of our common stock, and 2,225,000 warrants (the “Warrants”) to purchase up to 1,112,500 additional shares of our common stock. The Offering price was $2.24 per share of common stock and $0.01 per accompanying Warrant (for a combined Offering price of $2.25), initially raising $5.0 million in gross proceeds before underwriter discounts and offering-related expenses. The underwriting agreement (the “Underwriting Agreement”) we entered into with Maxim Group LLC (“Maxim”), as representative of the underwriters, for the Offering contained customary representations, warranties, and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and Maxim and certain other obligations.

Pursuant to the terms of the Underwriting Agreement, we granted to Maxim an option for a period of 45 days (the “Over-Allotment Option”) to purchase up to 225,000 additional shares of our common stock and 225,000 Warrants to purchase up to an additional 112,500 shares of our common stock. Effective as of the closing of the Offering, Maxim exercised the Over-Allotment Option for the purchase of 225,000 Warrants for a price of $0.01 per Warrant. On June 10, 2020, Maxim exercised the Over-Allotment Option for the purchase of 225,000 shares of our common stock for a price of $2.24 per share, before underwriting discounts. The closing of the sale of the over-allotment shares brought the total number of shares of common stock we sold in the Offering to 2,450,000 shares, and total gross proceeds to approximately $5.5 million. In addition, the Company received $0.5 million from investors in the Offering throughout the balance of 2020 due to the exercise of a portion of the Warrants sold in the Offering, bringing the total gross proceeds from equity issuance to $6.0 million.

The net proceeds to the Company from the Offering and Warrant exercises in 2020 were approximately $5.2 million (inclusive of the exercise of the over-allotment option), after deducting underwriter fees and offering-related expenses estimated at $0.8 million. We used a significant portion of the net proceeds from the Offering to fund working capital needs at our Building & Construction businesses, particularly related to modular housing projects which we produced at KBS for the for Boston-area projects. The remainder of the net proceeds is being used for working capital and for other general corporate purposes. We have broad discretion in determining how the proceeds of the Offering is used, and our discretion is not limited by the aforementioned possible uses.

Credit Facilities

Sterling Credit Facility

On March 29, 2019, the Company entered into a Loan and Security Agreement (the “SNB Loan Agreement”) by and among certain subsidiaries of the Company, as borrowers (collectively, the “SNB Borrowers”); the Company, as guarantor; and Sterling National Bank, a national banking association, as lender (“Sterling” or “SNB”).

The SNB Loan Agreement is a five-year credit facility maturing in March 2024, with a maximum credit amount of $20.0 million for revolving loans (the “SNB Credit Facility”). Under the SNB Credit Facility, the SNB Borrowers can request the issuance of letters of credit in an aggregate amount not to exceed $0.5 million at any one time outstanding. The borrowings under the SNB Loan Agreement were classified as short-term obligations under GAAP as the agreement contained a subjective acceleration clause and required a lockbox arrangement whereby all receipts are swept daily to reduce borrowings outstanding. As of December 31, 2020, the Company had $0.2 million of letters of credit outstanding and had additional borrowing capacity of $7.3 million.

At the Borrowers’ option, the SNB Credit Facility will bear interest at either (i) a Floating LIBOR Rate, as defined in the Loan Agreement, plus a margin of 2.50% per annum; or (ii) a Fixed LIBOR Rate, as defined in the Loan Agreement, plus a margin of 2.25% per annum. As our largest single debt outstanding, our floating rate on this facility at the end of 2020 was 2.64%.

The Company used a portion of the financing made available under the SNB Credit Facility to refinance and terminate, effective as of March 29, 2019, its previous credit facility with Comerica.

The SNB Loan Agreement includes certain representations, warranties of SNB Borrowers, as well as events of default and certain affirmative and negative covenants by the SNB Borrowers that are customary for loan agreements of this type. These covenants include restrictions on borrowings, investments and dispositions by SNB Borrowers, as well as limitations on the SNB Borrowers’ ability to make certain distributions. Upon the occurrence and during the continuation of an event of default under the SNB Loan Agreement, SNB may, among other things, declare the loans and all other obligations under the SNB Loan Agreement immediately due and payable and increase the interest rate at which loans and obligations under the SNB Loan Agreement bear interest. The SNB Credit Facility is secured by a first-priority security interest in substantially all of the assets of the Company and the SNB Borrowers and a pledge of all shares of the SNB Borrowers.

On March 29, 2019, in connection with the Company’s entry into the SNB Loan Agreement, Jeffery E. Eberwein, the Executive Chairman of the Company’s board of directors, entered into Limited Guaranty Agreement (the “SNB Eberwein Guaranty”) with SNB pursuant to which he guaranteed to SNB the prompt performance of all the Borrowers’ obligations to SNB under the SNB Loan Agreement, including the full payment of all indebtedness owing by Borrowers to SNB under or in connection with the SNB Loan Agreement and related SNB Credit Facility documents. Mr. Eberwein’s obligations under the SNB Eberwein Guaranty are limited in the aggregate to the amount of (a) $1.5 million, plus (b) reasonable costs and expenses of SNB incurred in connection with the SNB Eberwein Guaranty. Mr. Eberwein’s obligations under the SNB Eberwein Guaranty terminate upon the Company and Borrowers achieving certain milestones set forth therein.

In connection with the SNB Credit Facility, in the year ended December 31, 2019, the Company recognized a $0.2 million loss on extinguishment due to the write off of unamortized deferred financing costs associated with our prior revolving credit facility with Comerica.

At December 31, 2020 and 2019, the Company was in compliance with all covenants.

On February 1, 2021, we entered into an amendment to the SNB Loan Agreement, which is described in more detail in Note 19. Subsequent Events, within the notes to our accompanying consolidated financial statements.

ATRM Loan Agreements

As of December 31, 2020, ATRM had outstanding revolving lines of credit of approximately $3.1 million. Our debt through ATRM primarily included (i) $1.1 million principal outstanding on KBS’s $4.0 million revolving credit facility under a Loan and Security Agreement, dated February 23, 2016, (as amended, the “KBS Loan Agreement”), with Gerber Finance Inc. (“Gerber”) and (ii) $2.0 million principal outstanding on EBGL’s $3.0 million revolving credit facility under a Revolving Credit Loan Agreement, dated June 30, 2017 (as amended, the “Premier Loan Agreement”) with Premier Bank (“Premier”), net of an immaterial amount of unamortized financing fees. As of December 31, 2020, ATRM was at the maximum borrowing capacity under both revolving lines of credit, based on the inventory and accounts receivable on that day which fluctuates weekly.

See Note 16. Related Party Transactions, for information regarding certain ATRM promissory notes that are outstanding.

KBS Loan Agreement

On February 23, 2016, ATRM, KBS and Main Modular Haulers, Inc. (a subsidiary of ATRM) entered into a Loan and Security Agreement (as amended, the “KBS Loan Agreement”) with Gerber. The KBS Loan Agreement provides KBS with a revolving line of credit with borrowing availability of up to $4.0 million. Availability under the line of credit is based on a formula tied to KBS’s eligible accounts receivable, inventory and other collateral. The KBS Loan Agreement, which was scheduled to expire on February 22, 2018, has been automatically extended for successive one (1) year periods in accordance with its terms and is now scheduled to expire on February 22, 2022. The KBS Loan Agreement will be automatically extended for another one (1) year period unless a party thereto provides prior written notice of termination. As of December 31, 2020, neither party has provided notice of termination. Upon the final expiration of the term of the KBS Loan Agreement, the outstanding principal balance is payable in full. Borrowings bear interest at the prime rate plus 2.75%, equating to 6.00% at December 31, 2020, with interest payable monthly. The KBS Loan Agreement also provides for certain fees payable to Gerber during its term, including a 1.5% annual facilities fee and a 0.10% monthly collateral monitoring fee. KBS’s obligations under the KBS Loan Agreement are secured by all of its assets and are guaranteed by ATRM. Unsecured promissory notes issued by KBS and ATRM are subordinate to KBS’s obligations under the KBS Loan Agreement. The KBS Loan Agreement contains representations, warranties, affirmative and negative covenants, defined events of default and other provisions customary for financings of this type. Financial covenants require that KBS maintain a maximum leverage ratio (as defined in the KBS Loan Agreement) and KBS not incur a net annual post-tax loss in any fiscal year during the term of the KBS Loan Agreement. The borrowings under the KBS Loan Agreement were classified as short-term obligations under GAAP as the agreement contained a subjective acceleration clause and required a lockbox arrangement whereby all receipts are swept daily to reduce borrowings outstanding. At December 31, 2020, approximately $1.1 million was outstanding under the KBS Loan Agreement.

The parties to the KBS Loan Agreement have amended the KBS Loan Agreement to provide for increased availability under the KBS Loan Agreement to KBS under certain circumstances, including for new equipment additions, and certain other changes, as well as a waiver of certain covenants.

As of December 31, 2020 and 2019, KBS was not in compliance with the financial covenants requiring no net annual post-tax loss for KBS or the minimum leverage ratio covenant as of 2020. The occurrence of any event of default under the KBS Loan Agreement may result in KBS’s obligations under the KBS Loan Agreement becoming immediately due and payable. In April 2019, June 2019, February 2020 and February 2021, we obtained a waiver from Gerber for these events.

On September 10, 2019, the parties of the KBS Loan Agreement entered into a Consent and Acknowledgment Agreement and Twelfth Amendment to Loan Agreement (the “Twelfth Amendment”), by and among Gerber, KBS, ATRM and the Company, pursuant to which the Company agreed to guarantee amounts borrowed by certain ATRM’s subsidiaries from Gerber. The Twelfth Amendment requires the Company to serve as an additional guarantor with the existing guarantor, ATRM, with respect to the payment, performance and discharge of each and every obligation of payment and performance by the borrowing subsidiaries with respect to the loans made by Gerber to them. The Twelfth Amendment also provides that upon payment in full of the EBGL Obligations (as defined therein), the amount of the Cash Collateral (as defined therein) will be reduced to $0.3 million. Additionally, ATRM had on deposit $0.2 million in a collateral account maintained with Gerber to secure the loans under the KBS Loan Agreement which was returned to ATRM in November 2019.

On January 31, 2020, the Company, ATRM, KBS and Gerber entered into a Thirteenth Amendment to Loan and Security Agreement (the “Thirteenth KBS Loan Amendment”) to amend the terms of the KBS Loan Agreement, in order to, among other things (a) amend the definitions of “Ancillary Credit Parties,” “Guarantor,” “Obligations,” and “Subordinated Lender” to address the obligations of the Star Borrowers, the EBGL Borrowers, the Star Credit Parties, and the EBGL Credit Parties under the Star Loan Agreement, EBGL Loan Agreement and the Subordination Agreements (each as defined below) to which they are a party and (b) add a new cross default provision.

On March 5, 2020, in connection with the First EBGL Amendment, Gerber, KBS, ATRM and the Company entered into a Consent and as a Fourteenth Amendment to Loan and Security Agreement that amended the KBS Loan Agreement (the “Consent and Fourteenth Amendment”). Under the terms of the Consent and Fourteenth Amendment, the parties thereto (and the subordinated creditors that consented thereto) consented to the First EBGL Amendment and agreed that cash collateral would no longer be part of the borrowing base and that the borrowing base would no longer be based on cash availability for purposes of the KBS Loan Agreement.

On April 1, 2020, Gerber and KBS entered into a Fifteenth Amendment to Loan Agreement (the “Fifteenth Amendment”) pursuant to which the “Minimum Average Monthly Loan Amount” under the KBS Loan Agreement was decreased to twenty-five percent (25%) of the Maximum Revolving Amount (as defined in the KBS Loan Agreement).

On January 5, 2021, Gerber and KBS entered into a Sixteenth Amendment to Loan Agreement (the “Sixteenth Amendment”). The Sixteenth Amendment changed certain definitions under the KBS Loan Agreement to increase the inventory assets against which funds can be borrowed.

45

On February 26, 2021 Gerber and KBS entered into a Seventeenth Amendment to Loan Agreement (the Seventeenth Amendment”). The Seventeenth Amendment provided the waiver to the 2020 covenant breach and amended the financial covenants. The financial covenants under the KBS Loan Agreement, as amended, provide that (i) KBS shall make no distribution, transfer, payment, advance, or contribution of cash or property which would constitute a restricted payment; (ii) KBS shall report annual post-tax net income at least equal to (a) $385 thousand for the trailing 6-month period ending June 30, 2021 and b) $500 thousand for the trailing fiscal year end December 31, 2021; and (iii) a minimum EBITDA at June 30, 2021 of more than $880 thousand or at December 31, 2021 of more than $1.5 million.

EBGL Premier Note

On June 30, 2017, EdgeBuilder and Glenbrook (together, EBGL) entered into a Revolving Credit Loan Agreement (as amended, the “Premier Loan Agreement”) with Premier providing EBGL with a working capital line of credit of up to $3.0 million. The Premier Loan Agreement replaced the prior revolving credit facility under a loan and security agreement with Gerber (the “EBGL Loan Agreement”), which was terminated on the same date and all obligations of EBGL and ATRM in favor of Gerber in connection with the EBGL Loan Agreement were extinguished.

Availability under the Premier Loan Agreement is based on a formula tied to EBGL’s eligible accounts receivable, inventory and equipment, and borrowings bear interest at the prime rate plus 1.50%, with interest payable monthly and the outstanding principal balance payable upon expiration of the term of the Premier Loan Agreement. The Premier Loan Agreement also provides for certain fees payable to Premier during its term. The initial term of the Premier Loan Agreement was scheduled to expire on June 30, 2018, but was extended multiple times by Premier through January 31, 2023. The Premier Loan Agreement may be further extended from time to time at our request, subject to approval by Premier. EBGL’s obligations under the Premier Loan Agreement are secured by all of their inventory, equipment, accounts and other intangibles, fixtures and all proceeds of the foregoing.

On January 31, 2020, contemporaneously with the execution and delivery of the Star Loan Agreement and EBGL Loan Agreement described below, Glenbrook and EdgeBuilder entered into an Extension and Modification Agreement (the “Modification Agreement”) with Premier that modified the terms of the Revolving Credit Promissory Note (the “Premier Note”) made by Glenbrook and EdgeBuilder pursuant to the Premier Loan Agreement. Pursuant to the Modification Agreement, the amount of indebtedness evidenced by the Premier Note was reduced to $1.0 million, and the Premier Note was modified to, among other things: (a) extend the Final Maturity Date (as defined in the Premier Note) of the Premier Note to January 31, 2023, and (b) set the interest that the Premier Note will bear at 5.75% per annum. As a condition to close and to then later extend the term of the Premier Loan Agreement, ATRM and Mr. Eberwein executed a guaranty in favor of Premier, which has, through the multiple extensions described above, been extended through January 1, 2023, under which ATRM and Mr. Eberwein have absolutely and unconditionally guaranteed all of EBGL’s obligations under the Premier Loan Agreement. As of December 31, 2020, approximately $0.7 million was outstanding under the Premier Loan Agreement.

Gerber Star and EBGL Loans

On January 31, 2020, SRE, 947 Waterford Road, LLC (“947 Waterford”), 300 Park Street, LLC (“300 Park”), and 56 Mechanic Falls Road, LLC (“56 Mechanic” and together with SRE, 947 Waterford, and 300 Park, (the “Star Borrowers”), each an Investments Subsidiary, and the Company, ATRM, KBS, EdgeBuilder, and Glenbrook (collectively, the “Star Credit Parties”), entered into a Loan and Security Agreement (as amended, the “Star Loan Agreement”) with Gerber providing the Star Borrowers with a credit facility with borrowing availability of up to $2.5 million ($2.0 million and $0.5 million to KBS and EBGL, respectively) (the “Star Loan”). The advance of $2.0 million to KBS is to be repaid in monthly installments of sixty (60) consecutive equal payments. The advance of $0.5 million to EBGL, which has been temporarily increased by $0.3 million due to be repaid on April 30, 2020, is to be repaid in monthly installments of twelve (12) consecutive equal payments. On February 20, 2020, the Star Borrowers entered into a First Amendment to Loan and Security Agreement (the “First Star Amendment”) with Gerber that amended the Star Loan Agreement in order to (i) temporarily advance $0.3 million to EBGL, which amount is to be repaid to Gerber on or before April 30, 2020; (ii) clarify that Gerber can make multiple advances under the Star Loan Agreement, and (iii) to correct the maturity date of the Star Loan. On April 30, 2020, the Star Borrowers entered into a Second Amendment to Loan and Security Agreement (the “Second Star Amendment”) with Gerber that amended the Star Loan Agreement in order to change terms of repayment for the advance of $0.3 million to EBGL provided for under the First Star Amendment. Under the terms of the Second Star Amendment, the advance of $0.3 million to EBGL is to be repaid in three (3) consecutive equal monthly installments on the thirtieth (30th) day in each calendar month, commencing May 30, 2020, and in a final installment on or before July 31, 2020. As of September 30, 2020, EBGL repaid $0.3 million to Gerber. As of December 31, 2020, $1.6 million was outstanding under the Star Loan Agreement.

46

On January 31, 2020, EdgeBuilder and Glenbrook (the “EBGL Borrowers”), each a Construction Subsidiary, and the Company, Star, 947 Waterford, 300 Park, 56 Mechanic, ATRM, and KBS (collectively, the “EBGL Credit Parties”), entered into a Loan and Security Agreement (the “EBGL Loan Agreement”) with Gerber providing the EBGL Borrowers with a credit facility with borrowing availability of up to $3.0 million (the “EBGL Loan”).

On March 5, 2020, the EBGL Borrowers entered into a First Amendment to Loan and Security Agreement (the “First EBGL Amendment”) with Gerber that amended the EBGL Loan Agreement and the KBS Loan Agreement in order to, among other things, include a pledge $0.3 million of cash collateral by LSVI under the EBGL Loan Agreement which, prior to the First EBGL Amendment, was pledged by LSVI in connection with the KBS Loan Agreement. On July 1, 2020, the EBGL Borrowers entered into a Second Amendment to Loan and Security Agreement that amended the EBGL Loan Agreement in order to, among other things, terminate the pledge of $0.3 million in cash collateral. On February 26, 2021, the EBGL Borrowers entered into a third amendment to the EBGL Loan Agreement (the “Third EBGL Amendment”) pursuant to which the Company and Gerber agreed to, among other things, eliminate the minimum leverage ratio covenant, lower the minimum EBITDA, and require the borrowers to not incur a net operating loss on bi-annual basis. The Third EBGL Amendment also discharged the EBGL Eberwein Guaranty (described below) and removed Mr. Eberwein as an ancillary guarantor from the EBGL Loan Agreement. As of December 31, 2020 , $2.0 million was outstanding under the revolving credit facility.

Availability under the Star Loan Agreement is based on a formula tied to the value of real estate owned by the Star Borrowers, and borrowings bear interest at the prime rate plus 3.5% per annum. Availability under the EBGL Loan Agreement is based on a formula tied to the EBGL Borrowers’ eligible accounts receivable and inventory, and borrowings bear interest at the prime rate plus 2.75% per annum. The Loan Agreements also provide for certain fees payable to Gerber during their respective terms. The Star Loan matures on the earlier of (a) January 1, 2025 or (b) the termination, the maturity or repayment of the EBGL Loan. The EBGL Loan matures on the earlier of (a) January 1, 2022, unless extended, or (b) the termination, the maturity or repayment of the Star Loan. The maturity of the EBGL Loan is automatically extended for successive periods of one (1) year each unless terminated by Gerber or the EBGL Borrowers. The borrowings under the EBGL Loan Agreement were classified as short-term obligations under GAAP as the agreement contained a subjective acceleration clause and required a lockbox arrangement whereby all receipts are swept daily to reduce borrowings outstanding.

The obligations of the EBGL Borrowers under the EBGL Loan Agreement are guaranteed by the EBGL Credit Parties and are secured by substantially all the assets of the EBGL Borrowers and the EBGL Credit Parties.

The obligations of the Star Borrowers under the Star Loan Agreement are guaranteed by the Star Credit Parties and are secured by substantially all the assets of the Star Borrowers and the Star Credit Parties. Contemporaneously with the execution and delivery of the Star Loan Agreement, Jeffrey E. Eberwein, the Executive Chairman of the Company’s board of directors, executed and delivered a Guaranty (the “Gerber Eberwein Guaranty”) to Gerber pursuant to which he guaranteed the performance of all the Star Borrowers’ obligations to Gerber under the Star Loan Agreement, including the full payment of all indebtedness owing by the Star Borrowers to Gerber under or in connection with the Star Loan Agreement and related financing documents. Mr. Eberwein’s obligations under the Gerber Eberwein Guaranty are limited in the aggregate to the amount of (a) $2.5 million, plus (b) costs of Gerber incidental to the enforcement of the Gerber Eberwein Guaranty or any guaranteed obligations. On March 5, 2020, contemporaneously with the execution and delivery of the First EBGL Amendment, Mr. Eberwein, the Executive Chairman of the Company’s board of directors, executed and delivered a Guaranty (the “EBGL Eberwein Guaranty”) to Gerber pursuant to which he guaranteed the performance of all the EBGL Borrowers’ obligations to Gerber under the EBGL Loan Agreement, including the full payment of all indebtedness owing by the EBGL Borrowers to Gerber under or in connection with the EBGL Loan Agreement and related financing documents. Mr. Eberwein’s obligations under the EBGL Eberwein Guaranty are limited in the aggregate to the amount of (a) $0.5 million, plus (b) costs of Gerber incidental to the enforcement of the EBGL Eberwein Guaranty or any guaranteed obligations.

On February 26, 2021, the Star Borrowers entered into a third amendment to the Star Loan Agreement (the “Third Star Amendment”) with Gerber that, among other things, amended the contract rate to prime rate plus 3% and discharged the $2.5 million Gerber Eberwein Guaranty.

47

The Star Loan Agreement and EBGL Loan Agreement contains representations, warranties, affirmative and negative covenants, events of default and other provisions customary for financings of this type. The financial covenants under the EBGL Loan Agreement applicable to the EBGL Borrowers include maintenance of a minimum tangible net worth, a minimum debt service coverage ratio and minimum net income. The Financial covenants under the Star Loan Agreement applicable to the Star Borrowers include a minimum debt service coverage ratio. The occurrence of any event of default under the Loan Agreements may result in the obligations of the Borrowers becoming immediately due and payable. As of December 31, 2020, EBGL was not in compliance with the financial covenants under the Star Loan Agreement and EBGL Loan Agreement as of 2020. The occurrence of any event of default under the EBGL Loan Agreement may result in EBGL’s obligations under the EBGL Loan Agreement becoming immediately due and payable. In February 2021, we obtained a waiver from Gerber for these events and, as part of the Third EBGL Amendment (described above), the Company and Gerber agreed to, among other things, eliminate the minimum leverage ratio covenant, lower the minimum EBITDA, and require the borrowers to not incur a net operating loss on bi-annual basis, as well as discharge the EBGL Eberwein Guaranty.

As a condition to the extension of credit to the Star Borrowers and EBGL Borrowers under the Star Loan Agreement and EBGL Loan Agreement, the holders of certain existing unsecured promissory notes made by ATRM and certain of its subsidiaries entered into subordination agreements (the “Subordination Agreements”) with Gerber pursuant to which such noteholders (including the Company and certain of its subsidiaries) agreed to subordinate the obligations of ATRM and its subsidiaries to such noteholders to the obligations of the Star Borrowers and EBGL Borrowers to Gerber under the loan agreements.

Paycheck Protection Program

On April 30, 2020, each of KBS, EdgeBuilder and Glenbrook executed a separate promissory note evidencing unsecured loans under the “Paycheck Protection Program” (the “PPP”). The promissory note executed by KBS is for $0.8 million (the “KBS Note”), the promissory note executed by EdgeBuilder is for $0.2 million (the “EdgeBuilder Note”) and the promissory note executed by Glenbrook is for $0.2 million (the “Glenbrook Note”). The KBS Note, the EdgeBuilder Note and the Glenbrook Note, each dated April 30, 2020, are referred to together as the “Construction Notes”.

On May 11, 2020, the Company and each of Digirad Imaging Solutions, Inc. (“DIS”), DMS Imaging, Inc. (“DMS Imaging”) and DMS Health Technologies, Inc. (“DMS Health”), each a direct or indirect wholly owned subsidiary of the Company, executed a separate promissory note evidencing unsecured loans under the PPP. The promissory note executed by the Company, dated May 7, 2020, is for $0.8 million (the “Company Note”); the promissory note executed by DIS, dated May 5, 2020, is for $3.0 million (the “DIS Note”); the promissory note executed by DMS Imaging, dated May 5, 2020, is for $1.6 million (the “DMS Imaging Note”) and the promissory note executed by DMS Health, dated May 7, 2020, is for $0.1 million (the “DMS Health Note”). The Company Note, the DIS Note, the DMS Imaging Note, and the DMS Health Note are referred to together as the “Healthcare Notes”. The Construction Notes and the Healthcare Notes are referred to collectively as the “PPP Notes” and each promissory note individually as a “PPP Note”. As of December 31, 2020, the $1.6 million DMS Imaging Note, the $0.1 million DMS Health Note, and the $0.8 million Company Note were forgiven. In first quarter 2021, $0.4 million of the Glenbrook Note and EdgeBuilder Note, and $0.8 million of the KBS Note were forgiven; therefore, the DIS Loan is the only PPP Note that remains outstanding.

The PPP was established under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and is administered by the U.S. Small Business Administration (“SBA”). The loans evidenced by the Construction Notes are being made through Bremer Bank (“Bremer”) as lender, and the loans evidenced by the Healthcare Notes are being made through Sterling as lender.

The loans evidenced by the PPP Notes (the “PPP Loans”) have two-year terms and bear interest at a rate of 1.00% per annum. Monthly principal and interest payments under the PPP Loans are deferred for ten months after the end of covered periods. Beginning eleven months from the date of a PPP Note, unless fully forgiven prior thereto, the applicable borrower will pay to its lender thereunder a monthly principal and interest payments. The PPP Loans may be prepaid at any time prior to maturity with no prepayment penalties. The Construction Notes mature on April 30, 2022, and the Healthcare Notes mature two years from the date the loans under the Healthcare Notes are disbursed. Loans under the Company Note and the DIS Note were disbursed on May 12, 2020, and the loans under the DMS Health Note and DMS Imaging Note were disbursed on May 13, 2020.

The PPP Notes contain customary events of default relating to, among other things, payment defaults, making materially false and misleading representations to the SBA or lender, or breaching the terms of the applicable PPP Loan documents. Upon an event of default under a PPP Note, the lender thereunder may, among other things, require immediate payment of all amounts owing under the applicable PPP Note, collect all amounts owing from the applicable borrower, or file suit and obtain judgment.

48

Under the terms of the CARES Act, recipients of loans under the PPP can apply for and be granted forgiveness for all or a portion of the loan granted under the PPP. Such forgiveness will be determined, subject to limitations, based on the use of loan proceeds for payment of payroll costs and certain other eligible costs. However, no assurance is provided that forgiveness for any portion of the PPP Loans will be obtained and even if forgiveness is granted the PPP Loans may remain subject to review and audit due to all affiliated PPP Notes equaling more than $2 million.

In order to apply for the PPP Loans, we were required to certify, among other things, that the current economic uncertainty made the PPP Loans request necessary to support ongoing operations of the Company. This certification further required the Company to take into account its current business activity and its ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. The Company is continuing to evaluate the criteria and new guidance put out by the SBA regarding loan forgiveness and the procedures to seek loan forgiveness. As of December 31, 2020, $2.5 million of the Company Note, DMS Imaging Note and DMS Health Note were forgiven and in first Quarter 2021, an additional $1.2 million of the KBS Note, Glenbrook Note, and EdgeBuilder Note were forgiven. The Company has sought full loan forgiveness from the SBA for the DIS Note based on the satisfaction of applicable criteria and guidelines and is currently undergoing the mandated audit for all PPP loans over $2 million. PPP Loan forgiveness is sought under the belief that all entities requesting loan forgiveness have met the stated criteria and guidelines provided by the SBA and terms of the CARES Act; however, no assurance can be provided that forgiveness of the rest of PPP Loans will be obtained.

Off-Balance Sheet Arrangements

On September 10, 2019, the parties to the KBS Loan Agreement entered a Consent and Acknowledgment Agreement and Twelfth Amendment to Loan Agreement, by and among Gerber, KBS, ATRM and the Company, pursuant to which the Company agreed to guarantee amounts borrowed by certain of ATRM’s subsidiaries from Gerber. The Twelfth Amendment requires the Company to serve as an additional guarantor with the existing guarantor, ATRM, with respect to the payment, performance and discharge of each and every obligation of payment and performance by the borrowing subsidiaries with respect to the loans made by Gerber to them. On January 31, 2020, the Company, ATRM, KBS and Gerber entered into a Thirteenth Amendment to Loan and Security Agreement (the “Thirteenth KBS Loan Amendment”) to amend the KBS Loan Agreement, by and among the Company, ATRM, KBS and Gerber, in order to, among other things (a) amend the definitions of “Ancillary Credit Parties,” “Guarantor,” “Obligations,” and “Subordinated Lender” to address the obligations of the Star Borrowers, the EBGL Borrowers, the Star Credit Parties, and the EBGL Credit Parties under the Loan Agreements and the Subordination Agreements to which they are a party and (b) add a new cross default provision.

See Note 10. Debt, within the notes to our consolidated financial statements for further detail.

Critical Accounting Policies

Management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which are prepared in accordance with United States generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, related disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. We evaluate our estimates and judgments, the most critical of which are those related to business combination, revenue recognition, goodwill valuation, and income taxes. Furthermore, the impact on accounting estimates and judgements on the Company’s financial condition and results of operations due to COVID-19 has introduced additional uncertainties. We base our estimates and judgments on historical experience and other factors that we believe to be reasonable under the circumstances. Materially different results can occur as circumstances change and additional information becomes known.

During the twelve months ended December 31, 2020, we reclassified our Mobile Healthcare segment to assets held for sale. Assets and liabilities are classified as held for sale when all of the following criteria for a plan of sale have been met: (1) management, having the authority to approve the action, commits to a plan to sell the assets; (2) the assets are available for immediate sale, in their present condition, subject only to terms that are usual and customary for sale of such assets; (3) an active program to locate a buyer and other actions required to complete the plan to sell the assets have been initiated; (4) the sale of the assets is probable and is expected to completed within one year; (5) the assets are being actively marketed for a price that is reasonable in relation to their current fair value; and (6) actions required to complete he plan indicate that it is unlikely that significant changes to the plan will be made or the plan will be withdrawn. When all of these criteria have been met, the assets (and liabilities) are classified as held for sale in the balance sheet for the current and comparative reporting periods. Assets classified as held for sale are reported at the lower of their carrying value or fair value less costs to sell. Depreciation and amortization of assets ceases upon designation as held for sale. The assets and liabilities held for sale are recorded on our Consolidated Balance Sheets as Assets held for sale and Liabilities held for sale, respectively. The profits and losses are presented on the Consolidated Statements of Operations as discontinued operations for the current and prior periods.

49

Business Combination

Under the acquisition method of accounting, we allocate the fair value of the total consideration transferred to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition. The fair values assigned, defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants, are based on estimates and assumptions determined by management. We record the excess consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, as goodwill. These valuations require us to make significant estimates and assumptions, especially with respect to intangible assets.

In connection with certain of our acquisitions, additional contingent consideration is earned by the sellers upon completion of certain future performance milestones. In these cases, a liability is recorded on the acquisition date for an estimate of the acquisition date fair value of the contingent consideration by applying the income approach utilizing variable inputs such as anticipated future cash flows, risk-free adjusted discount rates, and nonperformance risk. Any change in the fair value of the contingent consideration subsequent to the acquisition date is recognized as general and administrative expense (income), in our consolidated statements of operations and comprehensive income. This method requires significant management judgment, including the probability of achieving certain future milestones and discount rates. Future changes in our estimates could result in expenses or gains.

Management typically uses the discounted cash flow method to value our acquired intangible assets. This method requires significant management judgment to forecast future operating results and establish residual growth rates and discount factors. The estimates we use to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our business and are based on available historical information and industry estimates and averages. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, we could experience impairment charges. In addition, we have estimated the economic lives of certain acquired assets and these lives are used to calculate depreciation and amortization expense. If our estimates of the economic lives change, depreciation or amortization expenses could be accelerated or slowed.

See “Trends and Drivers—Acquisition of ATRM Holdings, Inc.” above for a description of the ATRM Acquisition.

Revenue Recognition

Pursuant to ASC 606, Revenue from Contracts with Customers, we recognize revenue when a customer obtains control of promised goods or services. We record the amount of revenue that reflects the consideration that it expects to receive in exchange for those goods or services. We apply the following five-step model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation.

Revenue recognition is evaluated on a contract basis. Performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if we have an enforceable right to payment, including a reasonable profit margin. Determining if an enforceable right to payment includes a reasonable profit margin requires judgment and is assessed on a contract by contract basis. For contracts requiring over time revenue recognition, the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We use a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress towards completion is measured based on the costs incurred to date.

Goodwill valuation

We review goodwill for impairment on an annual basis during the fourth quarter, as well as when events or changes in circumstances indicate that the carrying value may not be recoverable. We begin the process by assessing qualitative factors in determining whether it is more likely than not that the fair value of reporting unit is less than its carrying amount. After performing the aforementioned assessment and upon review of the results of such assessment, we may begin performing impairment analysis by quantitatively comparing the fair value of the reporting unit to the carrying value of the reporting unit, including goodwill. Impairment charge for goodwill is recognized for the amount by which the carrying value of the reporting unit exceeds its fair value and such loss should not exceed the total goodwill allocated to the reporting unit.

The Company recorded goodwill of $8.2 million associated with the acquisition of ATRM during the year ended December 31, 2019. The Company recorded a goodwill impairment of $0.4 million for EBGL during the year ended December 31, 2020. See Note 9. Goodwill, for further information.

50

Income Taxes

We provide for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of differences between the tax basis of assets or liabilities and their carrying amounts in the financial statements. We provide a valuation allowance for deferred tax assets if it is more likely than not that these items will expire before we are able to realize their benefit. We calculate the valuation allowance in accordance with the authoritative guidance relating to income taxes, which requires an assessment of both positive and negative evidence regarding the realizability of these deferred tax assets when measuring the need for a valuation allowance. Significant judgment is required in determining any valuation allowance against deferred tax assets.

The authoritative guidance for income taxes defines a recognition threshold and measurement attributes for financial statement recognition and measurement of a tax provision taken or expected to be taken in a tax return. The guidance also provides direction on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. Under the guidance, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. We recognize interest and penalties related to uncertain tax positions as a component of the income tax provision.

New Accounting Pronouncements

See Note 3. Basis of Presentation and Significant Accounting Policies, within the notes to our accompanying consolidated financial statements for discussion of our discussion of new accounting pronouncements.

ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Debt obligations under four of our Company Loan Agreements are subject to variable rates of interest based on LIBOR, the administrative agent’s prime rate or the U.S. federal funds rate. A 100 basis point increase in the underlying interest rate would result in an additional annual interest expense of approximately $0.2 million, assuming related debt of $15.8 million, which is the amount of outstanding borrowings at December 31, 2020.

The Company’s approach to interest rate risk is to balance borrowings between fixed rate and variable rate debt as management deems appropriate. At December 31, 2020, the Company’s borrowings under the Credit Agreements are all at variable rates, except for ATRM Notes Payable and Paycheck Protection Program Loan.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Shareholders and Board of Directors

Star Equity Holdings, Inc.

Old Greenwich, Connecticut

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Star Equity Holdings, Inc. (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive loss, mezzanine and stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Restatement to Correct 2019 Misstatement

As discussed in Note 2 to the consolidated financial statements, the 2019 consolidated financial statements have been restated to correct a misstatement.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

53

Valuation of Goodwill

As described in Note 9 to the Company’s consolidated financial statements, the Company's consolidated goodwill balance was $9.5 million as of December 31, 2020 which was allocated between 3 reporting units. During the fourth quarter of 2020, the Company determined one of the reporting units was impaired and recorded an impairment loss of $0.4 million. To estimate the fair value of its reporting units, the Company uses both an income approach and a market approach. The income approach requires management to make significant estimates and judgments regarding future cash flows that are based on a number of factors including actual operating results, forecasted revenue and expenses, discount rate assumptions, and long-term growth rate assumptions. The market approach requires the use of multiples based on financial metrics for both acquisitions and peer group companies.

We identified the valuation of goodwill as a critical audit matter. The principal considerations for our determination are the subjective and complex assumptions used in determining the fair value of reporting units under both the income approach and market approach. Auditing these estimates and related assumptions involved especially challenging and subjective auditor judgment due to the nature and extent of audit evidence and effort required to address these matters, including the extent of specialized skill or knowledge needed.

The primary procedures we performed to address this critical audit matter included:

•Evaluating the reasonableness of management’s judgments and assumptions used in the income approach to forecasts of future revenues and expenses by performing certain procedures through: (i) comparing the forecasts to internal communications to management and the Board of Directors, (ii) evaluating the impact of alternative assumptions on the valuation and comparing to management’s estimate, and (iii) evaluating whether the forecasts were consistent with evidence obtained in other areas of the audit, including assessing the projected impact of the COVID-19 pandemic on the industry and the forecasted recovery period for the industry.

•Evaluating the reasonableness of management’s judgments in determining peer group companies under the market approach.

•Utilizing personnel with specialized knowledge and skill of valuation techniques to assist in: (i) testing the underlying source information utilized in the market approach, (ii) assessing the appropriateness and relative weighting of valuation methods, (iii) testing the mathematical accuracy of the Company’s calculations, (iv) evaluating the reasonableness of the discount rate used in the income approach, (v) evaluating the reasonableness of certain assumptions used in the market approach, and (vi) verifying the reasonableness of the fair value estimate derived from the market approach using comparable fair value data from comparable peer companies.

Going Concern Assessment

As described in Note 3 to the Company’s consolidated financial statements, the Company has incurred net losses from continuing operations, has an accumulated deficit and has net cash used in operations. As of December 31, 2020, the Company was in breach of certain covenants, for which the Company obtained waivers from the lender. The determination as to whether the Company can continue as a going concern contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Management concluded that the Company has sufficient liquidity and cash flows from operations to continue as a going concern for the next twelve months from the issuance of these consolidated financial statements which is dependent on management’s ability to execute their plans.

We identified the Company’s going concern assessment as a critical audit matter due to the subjective judgments and assumptions required of management in assessing going concern uncertainty and in preparing a forecast of future cash flows, covenant compliance and borrowing capacity. Auditing these matters involved challenging and subjective auditor judgment due to the nature and extent of audit evidence and effort required to address these matters.

The primary procedures we performed to address this critical audit matter included:

•Obtaining an understanding of management’s plan regarding future operations and sources of liquidity.

•Analyzing the reasonableness of management’s judgements and assumptions used in the forecast of future cash flows for the next twelve months from the issuance of these consolidated financial statements by comparing to historic cash flows and underlying management assumptions.

54

•Testing management’s forecast of compliance with debt covenants for the next twelve months from the issuance of these consolidated financial statements.

•Evaluating the potential impact of acceleration of debt due to any expected violation of covenants, assessing additional funding relating to commitments from a related party and the deferring of maturity dates for related party debt.

•Assessing management’s plans in the context of other audit evidence obtained during the audit to determine whether such information supported or contradicted the conclusions reached by management.

STAR EQUITY HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. The Company

Star Equity Holdings, Inc. (“Star Equity”, or the “Company”) is a diversified holding company with three divisions: Digirad Health, Star Building & Construction, and Star Real Estate & Investments. Star Equity, which was incorporated in Delaware in 1997, was formerly known as Digirad Corporation until it changed its name to Star Equity Holdings, Inc. effective January 1, 2021. Star Equity is a diversified holding company that operates the following three divisions: Healthcare, Building & Construction, and Real Estate and Investments. Unless the context requires otherwise, in this report the terms “we,” “us,” and, “our” refer to Star Equity and our wholly owned subsidiaries.

Digirad Health Division

Digirad Health designs, manufactures, and distributes diagnostic medical imaging products. Digirad Health operates in three businesses: Diagnostic Services, Diagnostic Imaging and Mobile Healthcare. The Diagnostic Services business offers imaging and monitoring services to healthcare providers as an alternative to purchasing the equipment or outsourcing the procedure. The Diagnostic Imaging business develops, sells, and maintains solid-state gamma cameras. The Mobile Healthcare business provides contract diagnostic imaging, including computerized tomography (“CT”), magnetic resonance imaging (“MRI”), positron emission tomography (“PET”), PET/CT, and nuclear medicine and healthcare expertise through a convenient mobile service. The Diagnostic Imaging business develops, sells, and maintains solid-state gamma cameras. On October 30, 2020, Star Equity entered into a Stock Purchase Agreement (the “DMS Purchase Agreement”) by and among Star Equity, Project Rendezvous Acquisition Corporation, a Delaware corporation and wholly owned subsidiary of Star Equity (“Seller”), DMS Health Technologies, Inc., a North Dakota corporation and wholly owned subsidiary of Seller (“DMS Health”), and Knob Creek Acquisition Corp., a Tennessee corporation (“Buyer”) pursuant to which, subject to the satisfaction or waiver of certain conditions, Buyer will purchase all of the issued and outstanding common stock of DMS Health, which operates the Mobile Healthcare business, from Seller (the “DMS Sale Transaction”). As a result of the entry into the DMS Purchase Agreement, as of December 31, 2020, the Mobile Healthcare business met the criteria to be classified as held for sale and is reported on the Consolidated Statement of Operations as discontinued operations and on the Consolidated Balance Sheet as Assets and Liabilities held for sale.

Star Building and Construction Division

Star Building and Construction manufactures modular housing units for commercial and residential applications. Star Building & Construction operates in two businesses: (i) modular building manufacturing and (ii) structural wall panel and wood foundation manufacturing, including building supply retail operations. The modular building manufacturing business services New England and is operated by KBS Builders, Inc. (“KBS”) in Maine. The structural wall panel and wood foundation manufacturing segment is operated by EdgeBuilder, Inc. (“EdgeBuilder”), and the retail building supplies are sold through Glenbrook Building Supply, Inc. (“Glenbrook” and together with EdgeBuilder, “EBGL”). EBGL is based in and services the Greater Minneapolis metropolitan area. KBS, EdgeBuilder and Glenbrook are wholly owned subsidiaries of Star Equity and are referred to collectively herein, and together with ATRM, as the “Construction Subsidiaries.”

Star Real Estate & Investments Division

Star Real Estate & Investments generates revenue from the lease of commercial properties and equipment through Star Real Estate Holdings USA, Inc. (“SRE”), a wholly owned subsidiary of Star Equity. Star Real Estate & Investments also includes our investment arm, Lone Star Value Management, LLC (“LSVM”), a wholly owned subsidiary of Star Equity and a Connecticut-based exempt reporting advisor. LSVM, which was previously a wholly owned subsidiary of ATRM, was acquired by the Company in the ATRM Acquisition. In April 2019, as an initial transaction to create the Company’s real estate division under SRE, the Company funded the initial purchase of three modular building manufacturing facilities in Maine and then leased those three properties to KBS. The funding of the assets acquisition was primarily through the revolver loan under our credit facility with Sterling National Bank (“Sterling” or “SNB”), a national banking association. LSVM, SRE and the subsidiaries of SRE that are included in this division are referred to collectively herein as the “Investments Subsidiaries.”

As of December 31, 2020, our business is organized into four reportable segments: Diagnostic Services, Diagnostic Imaging, Building and Construction, and Real Estate and Investments in the continuing operations. See Note 17. Segments, within the notes to our accompanying consolidated financial statements for financial data relating to our segments. For discussion purposes, we categorized our Diagnostic Services and Diagnostic Imaging reportable segments as “Digirad Health.”

Note 2. Restatement of Previously Issued Consolidated Financial Statements

In connection with the preparation of our consolidated financial statements, we identified certain material historical errors related to the classification of short-term and long-term debt. Specifically, we determined that our historical presentation of the Sterling National Bank (“SNB”) revolver and the EdgeBuilder and Glenbrook (“EBGL”) Gerber Finance revolving credit facility were not in accordance with ASC 470 Debt. We determined that our borrowings under these revolving credit agreements that include both a subjective acceleration clause and a requirement to maintain a traditional lock-box arrangement should be classified as short-term obligations. However, the SNB revolver matures in March 2024, and EBGL revolver has an automatic annual renewal feature.

The Company's previously filed annual report on Form 10-K for the fiscal year ended December 31, 2019, and its quarterly reports on Form 10-Q for the periods affected by the restatements, have not been amended. Accordingly, investors should no longer rely upon the Company's previously released financial statements for any quarterly or annual periods after and including March 31, 2019, and any earnings releases or other communications relating to these periods.

The following tables summarize the effects of the restatement adjustments on the Company’s restated consolidated balance sheet as of December 31, 2019 and for the first three quarters of the years ended December 31, 2020 and 2019. In addition to the restatement of the consolidated balance sheet, certain historical information within the notes to the consolidated financial statements has been restated to reflect the correction of the error.

The restatement adjustments in the table below reflects the impact of reclassifying $17.0 million SNB revolver balance from long-term to short-term debt and $0.7 million of the Premier Loan balance from short-term to long-term debt as of December 31, 2019.

Total liabilities remains unchanged for all periods presented below and there is no impact to the Consolidated Statements of Operations and Comprehensive Loss, Consolidated Statements of Cash Flows, or Consolidated Statements of Mezzanine and Stockholders’ Equity for the Year Ended December 31, 2019 and for the first three quarters of the years ended December 31, 2020 and 2019.

Note 3. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The consolidated financial statements are prepared in conformity with generally accepted accounting principles (“GAAP”) accepted in the United States of America and include the financial statements and our wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated. The divestiture of the Mobile Healthcare segment met the definition of a strategic shift that has a significant effect on our operations and financial results; therefore, the results of operations for the Mobile Healthcare segment have been presented as discontinued operations in accordance with ASC 205-20, Presentation of Financial Statements-Discontinued Operations for all periods presented. Additionally, Mobile Healthcare’s assets and liabilities as of December 31, 2020 and 2019 are separately presented as held for sale on the consolidated balance sheet. Unless otherwise noted, discussion within these notes to the consolidated financial statements relates to continuing operations. Refer to Note 4. Discontinued Operations for additional information.

Reverse Stock Split

On June 4, 2019, we completed a 1-for-10 reverse stock split of our common stock and reduced the number of authorized shares to 30 million. The reverse stock split did not affect the par value of our common stock. The terms of equity awards under our incentive plans, including the exercise price and number of shares issuable under outstanding awards were also converted in proportion to the reverse split ratio.

All authorized, issued, and outstanding stock and per share amounts contained in the accompanying consolidated financial statements have been adjusted to reflect the 1-for-10 Reverse Stock Split for all prior periods presented.

ATRM Merger

On September 10, 2019 (the “ATRM Acquisition Date”), we completed our acquisition of ATRM pursuant to an Agreement and Plan of Merger, dated as of July 3, 2019 (the “ATRM Merger Agreement”), among Star Equity, Digirad Acquisition Corporation, a Minnesota corporation and our wholly owned subsidiary (“Merger Sub”), and ATRM. Under the terms of the ATRM Merger Agreement, Merger Sub merged with and into ATRM, with ATRM surviving as a wholly owned subsidiary of Star Equity. ATRM is now doing business as Star Building & Construction.

At the effective time of the ATRM Merger, (i) each share of ATRM common stock was converted into the right to receive three one-hundredths (0.03) of a share of 10.0% Series A Cumulative Perpetual Preferred Stock, par value $0.0001 per share, of the Company (“Company Preferred Stock”) and (ii) each share of ATRM 10.00% Series B Cumulative Preferred Stock, par value $0.001 per share (“ATRM Preferred Stock”), converted into the right to receive two and one-half (2.5) shares of Company Preferred Stock, for an approximate aggregate total of 1.6 million shares of Company Preferred Stock. No fractional shares of Company Preferred Stock were issued to any ATRM shareholder in the ATRM Merger. Each ATRM shareholder who would otherwise have been entitled to receive a fraction of a share of Company common stock in the ATRM Merger received one whole share of Company Preferred Stock. See Note 6. Merger, for further detail.

Mezzanine Equity

Pursuant to the Certificate of Designations, Rights and Preferences of 10% Series A Cumulative Perpetual Preferred Stock of Star Equity Holdings, Inc. (formerly Digirad Corporation) (the “Certificate of Designations”), upon a Change of Control Triggering Event, as defined in the Certificate of Designations, holders of the Company Preferred Stock may require the Company to redeem the Company Preferred Stock at a price of $10.00 per share, plus any accumulated and unpaid dividends (a “Change of Control Redemption”). As this redemption feature of the shares is not solely within the control of the Company, the Company Preferred Stock does not qualify as permanent equity and has been classified as mezzanine or temporary equity. Company Preferred Stock is not redeemable and it was not probable that our Preferred Stock would become redeemable as of December 31, 2020 and 2019. Therefore, we are not currently required to accrete the Company Preferred Stock to its redemption value.

In addition to a Change of Control Redemption, the Certificate of Designations also provides that we may redeem (at our option, in whole or in part) Preferred Stock following the fifth anniversary of issuance of the Company Preferred Stock, at a cash redemption price of $10.00 per share, plus any accumulated and unpaid dividends.

Discontinued Operations

On October 30, 2020, we entered into the DMS Purchase Agreement to sell all of the issued and outstanding common stock of DMS Health, which operates our Mobile Healthcare business. The purchase price for the DMS Sale Transaction is $18.75 million in cash, subject to certain adjustments, including a working capital adjustment.

65

The completion of the DMS Sale Transaction is subject to receipt of certain consents and customary closing conditions. The DMS Sale Transaction is not subject to approval by our stockholders. The Purchase Agreement contains representations, warranties and covenants, Seller and DMS Health that are customary for a transaction of this nature. The Purchase Agreement also contains indemnification obligations of the parties thereto. Assuming the satisfaction or waiver of the closing conditions, the DMS Sale Transaction is expected to close in the first half of 2021.

Between the date of the DMS Purchase Agreement and the closing date, the Company and Seller have agreed to allow DMS Health and its subsidiaries to, among other things, operate their respective businesses in the ordinary course in all material respects, and to keep their respective businesses and operations intact.

For all periods presented in our consolidated statements of operations, all revenue, cost of revenues, expenses, and income taxes attributable to DMS, except as related to the impact of the decrease in the federal statutory tax rate (see Note 14. Income Taxes), have been aggregated under the caption “net loss from discontinued operations, net of income taxes.” Additionally, the related assets and liabilities associated with the discontinued operations are classified as held for sale in the consolidated balance sheet. Cash flows used in or provided by DMS operations as part of discontinued operations and prior year results reclassified to conform with the current presentation are disclosed in Note 4. Discontinued Operations. Unless otherwise noted, amounts and disclosures throughout these notes to consolidated financial statements relate to our continuing operations.

Liquidity

The accompanying consolidated financial statements have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and settlement of obligations in the normal course of business. We incurred net losses from continuing operations of approximately $7.2 million and $1.9 million for the years ended December 31, 2020 and 2019, respectively. We have an accumulated deficit of $125.0 million and $118.5 million as of December 31, 2020 and 2019, respectively. Net cash used in operations was $5.0 million for the year ended December 31, 2020 compared to net cash provided by operations of $0.4 million for the year ended 2019. The Company will need to secure additional future financing to accomplish its business plan over the next several years and that there can be no assurance on the availability or terms upon which such financing and capital mat be available in the future.

At December 31, 2020, we had approximately $4.3 million in short term debt due within the next twelve months for our Building and Construction division. We were in breach of certain debt covenants with Gerber, as further discussed in Note 10. Debt below. The debt held by related parties totaled approximately $2.3 million at December 31, 2020. In February 2021, as discussed more fully below, we refinanced our debt and obtained waivers with Gerber and reset the debt covenants with the lender.

We also had approximately $12.7 million in short term debt due to our borrowings under the Sterling National Bank revolving credit facility which is classified as short term as disclosed in Note 10. Debt and matures in March 2024. As of December 31, 2020, we were in compliance with all borrowing arrangements related to our Digirad Health division. The revolver directly supports our healthcare business, but up to $4 million may be drawn to fund non-healthcare operations as long as we maintain a $4 million cushion of excess availability following any non-healthcare distributions, and certain other requirements. As of December 31, 2020, we had $7.3 million of borrowing capacity to fund the operations of these divisions.

On May 28, 2020, we closed a public offering (the “Offering”) of 2,225,000 shares of its common stock and 2,225,000 warrants (“Warrants”) to purchase up to 1,112,500 shares of its common stock. Net proceeds of the Offering is being used to fund working capital and other general corporate purposes. Further, Jeffrey E. Eberwein, the Executive Chairman of our board of directors, has committed to provide financial support to us by providing written assurances that he will (a) not call approximately $2.3 million of related party debt when it becomes due in October 2020 then extended to June 30, 2022 and (b) extend through June 2021 our put option with respect to $1.0 million in Preferred Stock. In November 2020, Mr. Eberwein signed the second extension letter to extends the maturity date of all notes above to the earlier of (i) the date that is 5 business days after the Closing Date defined within the DMS Purchase Agreement dated October 30, 2020 between the Company and Knob Creek Acquisition Corp. or (ii) the date when the Note is no longer subject to a certain subordinate letter agreement dated January 12, 2018, as amended in favor of Gerber. Management believes that we have the liquidity and operations to continue to support the business through the next 12 months from the issuance of these consolidated financial statements. Our ability to continue as a going concern is dependent on ability to execute our plans.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and disclosures made in the accompanying notes to the consolidated financial statements. Significant estimates and judgments include those related to revenue recognition, allowances for doubtful accounts and contractual allowances, self-insurance, inventory valuation, and income taxes. Actual results could materially differ from those estimates.

66

Revenue Recognition

We recognize revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 and Topic 842 in the year of 2020 and 2019, which are explained below.

Pursuant to ASC 606, Revenue from Contracts with Customers, we recognize revenue when a customer obtains control of promised goods or services. We record the amount of revenue that reflects the consideration that it expects to receive in exchange for those goods or services. We apply the following five-step model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation.

Revenue recognition is evaluated on a contract by contract basis. Performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if we have an enforceable right to payment, including a reasonable profit margin. Determining if an enforceable right to payment includes a reasonable profit margin requires judgment and is assessed on a contract by contract basis. For contracts requiring over time revenue recognition, the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We use a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress towards completion is measured based on the costs incurred to date.

Healthcare Services Revenue Recognition. We generate service revenue primarily from providing diagnostic imaging and cardiac monitoring services to our customers. Service revenue within our Diagnostic Imaging reportable segments is derived from providing our customers with contract diagnostic imaging services, which includes use of our imaging systems, qualified personnel, radiopharmaceuticals, licensing, logistics and related items required to perform testing in their own offices.  We bill customers either on a per-scan or fixed-payment methodology, depending upon the contract that is negotiated with the customer. Within our Diagnostic Imaging Service segment, we also rent cameras to healthcare customers for use in their operations.  Rental revenues are structured as either a weekly or monthly payment arrangement, and are recognized in the month services are provided. Revenue related to provision of our services is recognized at the time services are performed.

Healthcare Product and Product-Related Revenue Recognition. We generate revenue from product and product-related sales, primarily from the sale of gamma cameras and accessories.

Diagnostic Imaging product revenues are generated from the sale of internally developed solid-state gamma camera imaging systems and camera maintenance service contracts. Revenue from sales of imaging systems is generally recognized at point in time upon delivery of systems and acceptance by customers. We also provide installation services and training on cameras sold, primarily in the United States. Installation and initial training is generally performed shortly after delivery and the revenue related to the provision of these services is recognized at the time services are performed. Neither installation nor training is essential to the functionality of the product. Finally, we offer camera maintenance service contracts that are sold beyond the term of the initial warranty, generally one year from the date of purchase. Revenue from these service contracts is deferred and recognized ratably over the period of the obligation.

Building and Construction Revenue Recognition.

Within the Building and Construction segment, we service residential and commercial construction projects by manufacturing modular housing units and other products and supplies general contractors with building materials. KBS manufactures modular buildings for both single-family residential homes and larger, commercial building projects. EdgeBuilder manufactures structural wall panels, permanent wood foundation systems and other engineered wood products, and Glenbrook is a retail supplier of lumber and other building supplies. Revenue is generally recognized at point in time upon delivery of product. Retail sales at Glenbrook are recognized at the point of sale. For bill and hold sales, we determine when the customer obtains control of the product on a case-by-case basis to determine the amount of revenue to recognize each period.

67

Leases

Lessee Accounting

We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and operating lease liabilities, net of current portion in our consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities, and other long-term liabilities in our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit discount rate when readily determinable; however, as most of our leases do not provide an implicit discount rate, we use an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease valuation may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

We elected to not separate lease and non-lease components of our operating leases in which it is the lessee and lessor. Additionally, the Company elected not to recognize right-of use assets and leases liabilities that arise from short-term leases of twelve months or less.

Lessor Accounting

We determine lease classification at the commencement date. Leases not classified as sales-type or direct financing leases are classified as operating leases. The primary accounting criteria used for  lease classification are (a) review to determine if the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (b) review to determine if the lease grants the lessee a purchase option that the lessee is reasonably certain to exercise, (c) determine, using a seventy-five percent or more threshold, if the lease term is for a major part of the remaining economic life of the underlying asset (however, we do not use this classification criterion when the lease commencement date falls within the last 25 percent of the total economic life of the underlying asset) and (d) determine, using a ninety percent or more threshold, if the present value of the sum of the lease payments and any residual value guarantees equal or exceeds substantially all of the fair value of the underlying asset. We do not lease equipment of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term.

We elected the operating lease practical expedient for leases to not separate non-lease components of regular maintenance services from associated lease components.

Property taxes paid by the lessor that are reimbursed by the lessee are considered to be lessor costs of owning the asset and are recorded gross with income included in other non-interest income and expense recorded in operating expenses. 

We selected a lessor accounting policy election to exclude from revenue and expenses sales taxes and other similar taxes assessed by a governmental authority on lease revenue-producing transactions and collected by the lessor from a lessee.

Operating lease equipment is carried at cost less accumulated depreciation. Operating lease equipment is depreciated to its estimated residual value using the straight-line method over the lease term or estimated useful life of the asset.

Rental revenue on operating leases is recognized on a straight-line basis over the lease term unless collectability is not probable. In these cases rental revenue is recognized as payments are received.

Concentration of Credit Risk

Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents, investments, and accounts receivable. We limit our exposure to credit loss by generally placing cash and investments in high credit quality financial institutions and investment grade corporate debt securities. Additionally, we have established guidelines regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity.

68

Fair Value of Financial Instruments

The authoritative guidance for fair value measurements defines fair value for accounting purposes, establishes a framework for measuring fair value, and provides disclosure requirements regarding fair value measurements. The guidance defines fair value as an exit price, which is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level of pricing observability. Financial instruments primarily consist of cash equivalents, equity securities, accounts receivable, other current assets, restricted cash, accounts payable, and other current liabilities. The carrying amount of other short-term and long term borrowings approximates fair value because of the relative short maturity of these instruments and interest rates we could currently obtain.

Cash and Cash Equivalents

We consider all investments with a maturity of three months or less when acquired to be cash equivalents.

Equity Securities

As of December 31, 2020 and 2019, securities consist of investments in equity securities that are publicly traded. Investments that are strategic in nature, with the intent to hold the investment over a several year period, are classified as other assets (non-current). Effective January 1, 2018, equity securities, with certain exceptions, are measured at fair value and changes in fair value are recognized in net income. During the year ended December 31, 2020, we recognized gains related to changes in fair value of $22 thousand in the statement of operations. During the year ended December 31, 2019, we recorded gains related to changes in fair value of $62 thousand.

Allowance for Doubtful Accounts, and Billing Adjustments

Accounts receivable consist principally of trade receivables from customers and government or third-party healthcare insurance providers, and are generally unsecured and due within 30 days. We regularly evaluate the collectability of our trade receivables and provide reserves for doubtful accounts based on our historical experience rate, known collectability issues and disputes, and our bad debt write-off history. Our estimates of collectability could be impacted by material amounts due to changed circumstances, such as a higher number of defaults or material adverse changes in a payor’s ability to meet its obligations. Expected credit losses related to trade accounts receivable are recorded as an allowance for doubtful accounts within accounts receivable, net in the consolidated balance sheets, and the related provision for doubtful accounts is charged to general and administrative expenses.

Within the Diagnostic Services segment, we record a provision for billing adjustments, which are based on our historical experience rate of billing adjustments history. The provision for billing adjustments is charged against Diagnostic Services revenues.

Within the Building and Construction segment, accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is our best estimate of losses that may result from uncollectable accounts receivable. We determine the allowance based on an analysis of individual accounts and an evaluation of the collectability of our accounts receivable in the aggregate based on factors such as the aging of receivable amounts, customer concentrations, historical experience, and current economic trends and conditions. Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. We do not have any off-balance sheet credit exposure related to our customers.

The following table summarizes the allowance for doubtful accounts, billing adjustments, and contractual allowances as of and for the years ended December 31, 2020, and 2019 (in thousands):

	Allowance for  Doubtful Accounts (1)			Reserve for  Billing Adjustments (2)

The amounts above exclude $10 thousand and $13 thousand of Allowance for Doubtful Accounts at Mobile Healthcare classified as held for sale as of December 31, 2020 and December 31, 2019, respectively. See Note 4. Discontinued Operations, for additional information.

Inventory

Inventories are stated at the lower of cost (first-in first-out basis) or net realizable value. Finished goods and work-in-process inventory values include the cost of raw materials, labor and manufacturing overhead. Inventory when written down to net realizable value establishes a new cost basis and its value is not subsequently increased based upon changes in underlying facts and circumstances. We also make adjustments to reduce the carrying amount of inventories for estimated excess or obsolete inventories. Factors influencing these adjustments include inventories on-hand compared with historical and estimated future sales for existing and new products and assumptions about the likelihood of obsolescence.

The following table summarizes our reserves for excess and obsolete inventory as of and for the years ended December 31, 2020 and 2019 (in thousands):

	Reserve for Excess and Obsolete Inventories (1)
Balance at December 31, 2018		$	380

Write-offs and scrap		(47)
Balance at December 31, 2019		383
Provision adjustment		137
Write-offs and scrap		(121)
Balance at December 31, 2020		$	399

(1)The provision was charged against Product and product-related cost of revenues.

Long-Lived Assets including Finite Lived Purchased Intangible Assets

Long-lived assets consist of property and equipment and finite lived intangible assets. We record property and equipment at cost, and record other intangible assets based on their fair values at the date of acquisition. We calculate depreciation on property and equipment using the straight-line method over the estimated useful life of the assets, which range from 5 to 20 years for buildings and improvements, 3 to 13 years for machinery and equipment, 1 to 10 years for computer hardware and software, and the lesser of the estimated useful life or remaining lease term for leasehold improvements. Charges related to amortization of assets recorded under capital leases are included within depreciation expense. We calculate amortization on other intangible assets using either the accelerated or the straight-line method over the estimated useful life of the assets, based on when we expect to receive cash inflows generated by the intangible assets. Estimated useful lives for intangibles range from 1 to 15 years.

Impairment losses on long-lived assets used in operations are recorded when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. No impairment was recorded on long-lived assets to be held and used during the years ended December 31, 2020 and 2019.

Valuation of Goodwill

We review goodwill for impairment on an annual basis during the fourth quarter, as well as when events or changes in circumstances indicate that the carrying value may not be recoverable. We begin the process by assessing qualitative factors in determining whether it is more likely than not that the fair value of reporting unit is less than its carrying amount. After performing the aforementioned assessment and upon review of the results of such assessment, we may begin performing impairment analysis by quantitatively comparing the fair value of the reporting unit to the carrying value of the reporting unit, including goodwill. Impairment charge for goodwill is recognized for the amount by which the carrying value of the reporting unit exceeds its fair value and such loss should not exceed the total goodwill allocated to the reporting unit.

Goodwill has historically been derived from the acquisition of ATRM in 2019, MD Office Solutions (“MD Office”) in 2015, and substantially all of the assets of Ultrascan, Inc. (“Ultrascan”) in 2007. Digirad Imaging Solutions, KBS and EBGL are the reporting units that carry a goodwill balance of $1.7 million, $3.8 million, and $4.0 million, respectively. A goodwill impairment of $0.4 million was recorded for the year ended December 31, 2020. See Note 9. Goodwill, for further information.

Self-Insured Health Insurance Benefits

Digirad Health provides healthcare benefits to its employees through a self-insured plan with “stop loss” coverage. The Company records a liability that represents our estimated cost of claims incurred and unpaid as of the balance sheet date.  Our estimated reserve is based on historical experience and trends related to both health insurance claims and payments.  The ultimate cost of healthcare benefits will depend on actual costs incurred to settle the claims and may differ from the amounts reserved by the Company for those claims. As of December 31, 2020 and 2019, the reserve for estimated claims incurred and unpaid was $0.5 million and $0.5 million, respectively.

Restricted Cash

We maintain certain cash amounts restricted as to withdrawal or use. As of December 31, 2020 and 2019, restricted cash was $0.2 million and $0.2 million, respectively, comprised of cash held for letters of credit for our real estate leases and certain minimum balance requirements on our banking arrangements.

Debt Issuance Costs

We incur debt issuance costs in connection with debt financings. Debt issuance costs recorded in connection with our Sterling National Bank, Gerber, and Premier Bank revolving credit facility are presented in other assets on the consolidated balance sheets and are amortized over the term of the revolving debt agreements using the straight-line method. Amortization of debt issuance costs are included in interest expense. As of December 31, 2020 and 2019, we have $0.6 million and $0.6 million, respectively, of unamortized debt issuance costs.

Shipping and Handling Fees and Costs

We record all shipping and handling costs billed to customers as revenue earned for the goods provided. Shipping and handling costs related to continuing operations are included in cost of revenues and totaled $1.0 million and $0.7 million for the years ended December 31, 2020 and 2019, respectively. Shipping and handling costs included in discontinued operations totaled $24 thousand and $34 thousand for the years ended December 31, 2020 and 2019, respectively.

Share-Based Compensation

We account for share-based awards exchanged for employee and board services in accordance with the authoritative guidance for share-based compensation. Under this guidance, share-based compensation expense is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense, net of forfeitures, over the requisite service period.

Warranty

In Digirad Health, we generally provide a 12-month assurance warranty on our gamma cameras. We accrue the estimated cost of this warranty at the time revenue is recorded and charge warranty expense to product and product-related cost of revenues. Warranty reserves are established based on historical experience with failure rates and repair costs and the number of systems covered by warranty. Warranty reserves are depleted as gamma cameras are repaired. The costs consist principally of materials, personnel, overhead, and transportation. We review warranty reserves quarterly and, if necessary, make adjustments.

Within our Building and Construction segment, KBS provides a limited assurance warranty on its residential homes that covers substantial defects in materials or workmanship for a period of 12 months after delivery to the owner. EBGL provides a limited warranty on the sale of its wood foundation products that covers leaks resulting from defects in workmanship for a period of twenty-five years. Estimated warranty costs are accrued in the period that the related revenue is recognized.

The activities related to our warranty reserve for the years ended December 31, 2020 and 2019 are as follows (in thousands):

	Year Ended December 31,
	2020		2019
Balance at beginning of year	$	421	$	197

Advertising Costs

Advertising costs are expensed as incurred. Total advertising costs in continuing operations for the years ended December 31, 2020 and 2019 were $0.1 million and $0.3 million, respectively. Total advertising costs in discontinued operations for each of the years ended December 31, 2020 and 2019 were $7 thousand and $11 thousand, respectively.

Basic and Diluted Net Loss Per Share

We present net loss per share attributable to common stockholders in conformity with the two-class method required for participating securities, as the warrants are considered participating securities. We have not allocated net loss attributable to common stockholders to warrants because the holders of our warrants are not contractually obligated to share in our losses. Basic net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per share attributable to common stockholders is calculated to give effect to all potential shares of common stock, including common stock issuable upon exercise of warrants, stock options, and restricted stock units. In periods for which there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive.

The following table sets forth the reconciliation of shares used to compute basic and diluted net loss per share for the years ended December 31, 2020 and 2019 (in thousands):

	Year Ended December 31,
	2020		2019
Numerator:
Net loss from continuing operations	$	(5,285)	$	(2,740)
Net loss from discontinued operations	(1,172)		(1,887)
Net loss	(6,457)		(4,627)
Deemed dividend on Series A perpetual preferred stock	(1,916)		(596)
Net loss attributable to common shareholders	$	(8,373)	$	(5,223)
Denominator:
Weighted average shares outstanding - basic and diluted	3,659		2,041
Net loss per common share - basic and diluted*
Net loss per share, continuing operations	$	(1.44)	$	(1.34)
Net loss per share, discontinued operations	$	(0.32)	$	(0.92)
Net loss per share	$	(1.76)	$	(2.27)
Deemed dividend on Series A perpetual preferred stock per share	$	(0.52)	$	(0.29)
Net loss per share, attributable to common shareholders - basic and diluted	$	(2.29)	$	(2.56)

*Earnings per share may not add due to rounding

Antidilutive common stock equivalents are excluded from the computation of diluted loss per share. Stock options and restricted stock units are antidilutive when the assumed proceeds per share are greater than the average market price of the common shares. In addition, in periods where net losses are incurred, stock options and restricted stock units with assumed proceeds per share less than the average market price of the common shares become antidilutive as well. The following weighted-average outstanding common stock equivalents were not included in the calculation of diluted net loss per share because their effect was antidilutive (in thousands):

	Year Ended December 31,
	2020	2019
Stock options	43	54
Stock warrants	1,247	—
Restricted stock units	26	24
Total	1,316	78

72

As of December 31, 2020, there were 486,140 warrants exercised and 1,963,860 warrants remained outstanding at an exercise price of $2.25.

Other Comprehensive Income (Loss)

Other comprehensive income (loss) is defined as revenues, expenses, gains and losses that under GAAP are included in comprehensive income (loss) but excluded from net income (loss).

Income Taxes

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

We recognize net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If management determines that we would be able to realize deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

We record uncertain tax positions on the basis of a two-step process whereby (1) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. We recognize interest and penalties related to unrecognized tax benefits within income tax expense, and any accrued interest and penalties would be included within the related tax liability. No such costs were recorded for the years ended December 31, 2020 and December 31, 2019.

New Accounting Standards To Be Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. This update is effective for annual periods beginning after December 15, 2022, and interim periods within those periods, and early adoption is permitted. We expect to adopt the standard on its effective date in the first quarter of 2023. We believe the adoption will modify the way we analyze financial instruments, but currently do not expect the adoption to have a material financial impact on our consolidated financial statements.

Note 4. Discontinued Operations

On February 1, 2018, we completed the sale of customer contracts relating to our Medical Device Sales and Service (“MDSS”) post-warranty service business to Philips pursuant to an Asset Purchase Agreement, dated as of December 22, 2017 for $8.0 million. The total cash proceeds were adjusted for deferred revenue liabilities assigned to Philips at the closing date, as well as $0.5 million of proceeds held in escrow, subject to claims for breaches of general representation and warranties, which was recorded in other current assets at the date of sale.

As of December 31, 2019, we recognized a $350 thousand gain for the remaining settlement of the warranty claims in regards to equipment sold to Phillips.

On November 3, 2020, we announced the sale of its DMS Health Technologies, Inc. business unit. The purchase price under the DMS Purchase Agreement is $18.75 million in cash, subject to certain adjustments, including a working capital adjustment. We deemed the disposition of the Mobile Healthcare business unit to represent a strategic shift that will have a major effect on our operations and financial results. As of December 31, 2020, the Mobile Healthcare business met the criteria to be classified as held for sale. This segment is reported on the Consolidated Statement of Operations as discontinued operations and on the Consolidated Balance Sheet as Assets and Liabilities held for sale.

73

We allocated a portion of interest expense to discontinued operations since the proceeds received from the sale were required to be used to pay down outstanding borrowings under our revolving credit facility with Sterling National Bank. The allocation was based on the ratio of assets generated based on the borrowing capacity to total borrowings capacity for the period. In addition, certain general and administrative costs related to corporate and shared service functions previously allocated to the mobile healthcare reportable segment are included in discontinued operations.

The following table summarizes the DMS and MDSS results for the years ended December 2020 and 2019 (in thousands):

Note 5. Revenue

Healthcare Product and Product-Related Services Revenues and Services Revenue

Healthcare Product and product-related services revenue are generated from the sale of gamma cameras, accessories and post-warranty maintenance service contracts within our Diagnostic Imaging reportable segment.

Healthcare Imaging services revenue are generated from providing diagnostic imaging services to customers within our Diagnostic Services reportable segment. Services revenue also includes lease income generated from interim rentals of imaging systems to our customers.

Building and Construction

Building and Construction revenue is generated from selling modular buildings for both single-family residential homes, larger commercial building projects and selling structural wall panels, permanent wood foundation systems and other engineered wood products.

Real Estate and Investments

Star Real Estate Holdings USA, Inc. (“SRE”) generates revenue from the lease of commercial properties and equipment and Lone Star Value Management, LLC (“LSVM”), a Connecticut based exempt reporting advisor, provides services that include investment advisory services, and the servicing of pooled investment vehicles.

Revenue Recognition

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue.

The majority of our contracts have a single performance obligation, as we provide a series of distinct goods or services that are substantially the same and are transferred with the same pattern to the customer. For contracts with multiple performance obligations, we allocate the total transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We use an observable price to determine the stand-alone selling price for separate performance obligations or a cost plus margin approach when one is not available. For bill and hold sales, we determine when the customer obtains control of the product on a case-by-case basis to determine the amount of revenue to recognize each period.

Revenue recognition is evaluated on a contract by contract basis. Performance obligations are satisfied over time as work progresses or at a point-in-time. A performance obligation is satisfied over time if the Company has an enforceable right to payment, including a reasonable profit margin. Determining if an enforceable right to payment includes a reasonable profit margin requires judgment and is assessed on a contract by contract basis. For contracts requiring over time revenue recognition, the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company uses a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress towards completion is measured based on the costs incurred to date.

Our products are generally not sold with a right of return and the Company does not provide significant credits or incentives, which may be variable consideration when estimating the amount of revenue to be recognized.

Nature of Goods and Services

Mobile Imaging

Within our Diagnostic Services segment, our sales are derived from providing services and materials to our customers, primarily physician practices and hospitals, that allow them to perform diagnostic imaging services at their site. We typically bundle our services in providing staffing, our imaging systems, licensing, radiopharmaceuticals, and supplies depending on our customers’ needs. Our contracts with customers are typically entered into annually and are billed on a fixed rate per-day or per-scan basis, depending on terms of the contract. For the majority of these contracts, the Company has the right to invoice the customer in an amount that directly corresponds with the value to the customer as the Company performs the services. The Company uses the practical expedient to recognize revenue corresponding with amounts we have the right to invoice for services performed.

77

Camera

Within our Diagnostic Imaging segment, camera revenues are generated from the sale of internally developed solid-state gamma camera imaging systems and accessories. We recognize revenue upon transfer of control to the customer at a point-in-time, which is generally upon delivery and acceptance. We also provide installation services and training on cameras we sell, primarily in the United States. Installation and initial training is generally performed shortly after delivery. The Company recognizes revenues for installation and training over time as the customer receives and consumes benefits provided as the Company performs the installation services.

Our sale of imaging systems includes a one-year assurance-type warranty. The estimated costs associated with our standard warranties and field service actions are recognized as expense when cameras are sold. Maintenance service contracts sold beyond the term of our standard warranties are accounted for as a service-type warranty and revenue is deferred and recognized ratably over the period of the warranty obligation.

Camera Support

Within our Diagnostic Imaging segment, camera support revenue is derived from the sale of separately-priced extended maintenance contracts to camera owners, training, and the sale of parts to customers that do not have an extended warranty. Our separately priced service contracts range from 12 to 48 months. Service contracts are usually billed at the beginning of the contract period or at periodic intervals (e.g., monthly, quarterly, or annually) and revenue is recognized ratably over the term of the agreement.

Services and training revenues are recognized over time in the period the services and training are performed. Revenue for sales of parts are recognized when the parts are delivered to the customer and control is transferred.

Lease Income

Within primarily our Diagnostic Service segment, we also generate income from rentals of state-of-the-art equipment including cameras, ultrasound machines to customers. Rental contracts are structured as either a weekly or monthly payment arrangement and are accounted for as operating leases. Revenues are recognized on a straight-line basis over the term of the rental.

Within our Building and Construction segment, we subleased the manufacturing building located in Waterford, Maine to a commercial tenant pursuant to a rental agreement with an initial 5 year term that commenced on September 6, 2019. The rental agreement is structured with a monthly payment arrangement and is accounted for as an operating lease.

Building and Construction

Within the Building and Construction segment, we service residential and commercial construction projects by manufacturing modular housing units and other products and supply general contractors with building materials. KBS manufactures modular buildings for both single-family residential homes and larger, commercial building projects. EdgeBuilder manufactures structural wall panels, permanent wood foundation systems and other engineered wood products, and Glenbrook is a retail supplier of lumber and other building supplies. Revenues are evaluated on a contract by contract basis. In general, construction revenues are recognized upon transfer of control to the customer at a point-in-time, which is generally upon delivery and acceptance. However, it is recognized over time for arrangements with customers for which : (i) performance does not create an asset with an alternative use, and (ii) we have an enforceable right to payment, including a reasonable profit margin, for performance completed to date.

We record deferred revenues when cash payments are received in advance of our performance. We have determined our contracts do not include a significant financing component. The majority of our deferred revenue relates to payments received on camera support post-warranty service contracts, which are billed at the beginning of the annual contract period or at periodic intervals (e.g., monthly, quarterly, or annually).

Changes in the deferred revenues for the year ended December 31, 2020 and 2019, is as follows (in thousands):

Balance at December 31, 2018	$	1,713
ATRM beginning balance (1)	317
Revenue recognized that was included in balance at beginning of the year	(1,477)
Deferred revenue, net, related to contracts entered into during the year	1,248
Balance at December 31, 2019	1,801
Revenue recognized that was included in balance at beginning of the year	(1,494)
Deferred revenue, net, related to contracts entered into during the year	2,045
Balance at December 31, 2020	$	2,352

(1) Contract liabilities assumed on business combination

As of December 31, 2020 and 2019, non-current deferred revenue for continuing operations was $168 thousand and $15 thousand, respectively. See Note 4. Discontinued Operations for deferred revenue included in discontinued operations.

The Company has elected to use the practical expedient under ASC 606 to exclude disclosures of unsatisfied remaining performance obligations for (i) contracts having an original expected length of one year or less or (ii) contracts for which the practical expedient has been applied to recognize revenue at the amount for which it has a right to invoice.

Contract Costs

We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. The Company applies a practical expedient to expense costs as incurred for costs to obtain a contract when the amortization period would have been one year or less. These costs mainly include the internal sales commissions; under the terms of these programs these are generally earned and the costs are recognized at the time the revenue is recognized.

Note 6. Merger

On September 10, 2019 (the “ATRM Acquisition Date”), Star Equity completed its acquisition of ATRM pursuant to an Agreement and Plan of Merger, dated as of July 3, 2019 (the “ATRM Merger Agreement”), among Star Equity, Digirad Acquisition Corporation, a Minnesota corporation and wholly owned subsidiary of Star Equity (“Merger Sub”), and ATRM. Under the terms of the ATRM Merger Agreement, Merger Sub merged with and into ATRM, with ATRM surviving as a wholly owned subsidiary of Star Equity. As a result of the ATRM Merger, ATRM’s operations have been included in our consolidated financial statements since the ATRM Acquisition Date.

ATRM, through its wholly-owned subsidiaries, KBS, Glenbrook, and EdgeBuilder, services residential and commercial construction projects by manufacturing modular housing units, structural wall panels, permanent wood foundation systems, and other engineered wood products and supplies general contractors with building materials. LSVM, which was a wholly owned subsidiary of ATRM on the ATRM Acquisition Date, is a Connecticut based exempt reporting advisor that was acquired by the Company in the ATRM Acquisition.

At the effective time of the ATRM Merger, (i) each share of ATRM common stock was converted into the right to receive three one-hundredths (0.03) of a share of 10.0% Series A Cumulative Perpetual Preferred Stock, par value $0.0001 per share, of the Company (Company Preferred Stock) and (ii) each share of ATRM 10.00% Series B Cumulative Preferred Stock, par value $0.001 per share (ATRM Preferred Stock), converted into the right to receive two and one-half (2.5) shares of Company Preferred Stock, for an approximate aggregate total of 1.6 million shares of Company Preferred Stock. No fractional shares of Company Preferred Stock were issued to any ATRM shareholder in the ATRM Merger. Each ATRM shareholder who would otherwise have been entitled to receive a fraction of a share of Company common stock in the ATRM Merger received one whole share of Company Preferred Stock.

The acquisition-date fair value of the consideration transferred in connection with the ATRM Merger approximately $17.5 million, which consisted of the following (in thousands, except share data):

Digirad Series A Cumulative Perpetual Preferred Stock (1,615,637 shares)	$	16,156
Settlement of pre-existing note receivable between DRAD and ATRM	296
Fair value of pre-existing joint venture settlement between DRAD and ATRM	1,000
Estimated purchase price	$	17,452

The fair value of the preferred shares issued was determined based on the product of (a) $10.00 (the stated liquidation preference per share of Company Preferred Stock), and (b) 1,615,637 (the number of shares of Company Preferred Stock were issued and exchanged in the ATRM Merger).

The following table summarizes the fair values of the assets acquired and liabilities assumed at the ATRM Acquisition Date (in thousands):

$11.3 million and $8.2 million of $19.5 million intangibles were assigned to KBS and EBGL reporting units, respectively. $4.0 million and $4.3 million of $8.2 million goodwill were allocated to KBS and EBGL reporting units, respectively. The goodwill recognized is attributable primarily to expected synergies and the assembled workforce of KBS and EBGL. As of December 31, 2019, there was a subsequent measurement of goodwill and a related tax benefit adjustment that resulted in a net adjustment of $3.0 thousand to the recognized amounts of goodwill resulting from the acquisition of ATRM.

The Company recognized $2.3 million of acquisition related costs including legal, accounting that were expensed during the year ended December 31, 2019. These costs are included in the consolidated statement of operations in the line item entitled “Merger and financing costs.”

The amounts of revenue and earnings of ATRM included in the Company’s consolidated statement of operations from the ATRM Acquisition Date for the year ended 2019 are as follows (in thousands):

	Year Ended December 31,

Subsequent to the ATRM Merger, all lease payments and obligations between the entities are eliminated on consolidation.

KBS subleased the manufacturing building located in Waterford, Maine to North Country Steel Inc., a Maine corporation with an initial 5 year term rental agreement, commenced on September 6, 2019. The rental agreement is structured with a monthly payment arrangement and is accounted for as operating lease. Refer to lease income discussed in Note 5. Revenue.

Note 8. Fair Value Measurements

We categorize our assets and liabilities measured at fair value into a three-level hierarchy in accordance with the authoritative guidance for fair value measurements. Assets and liabilities presented at fair value in our consolidated balance sheets are generally categorized as follows:

Level 1:Quoted prices in active markets for identical assets or liabilities.

Level 2:Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

83

Level 3:Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Such assets and liabilities may have values determined using pricing models, discounted cash flow methodologies, or similar techniques, and include instruments for which the determination of fair value requires significant management judgment or estimation.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of assets and liabilities and their placement within the fair value hierarchy levels. The following table sets forth by level within the fair value hierarchy our assets that were recorded at fair value as of December 31, 2020 and 2019 (in thousands):

	At Fair Value as of December 31, 2020
	Level 1		Level 2		Level 3		Total
Assets:
Equity securities	$	35	$	55	$	—	$	90
Total	$	35	$	55	$	—	$	90

	At Fair Value as of December 31, 2019
	Level 1		Level 2		Level 3		Total
Assets:
Equity securities	$	26	$	43	$	—	$	69
Lumber derivative contracts	10		—		—		10
Total	$	36	$	43	$	—	$	79

The investment in equity securities consists of common stock of publicly traded companies. The fair value of these securities is based on the closing prices observed on December 31, 2020 and 2019, respectively. During the year ended December 31, 2020, and 2019, we recorded in the statement of operations unrealized gains of $22 thousand and $62 thousand, respectively.

We occasionally enter into lumber derivative contracts in order to protect our gross profit margins from fluctuations caused by volatility in lumber prices. At December 31, 2020, we had no derivative contracts. At December 31, 2019, we had a net long (buying) position of 770,000 board feet under seven lumber derivatives contracts and had a short position of 770,000 board feet under seven lumber derivative contracts.

At December 31, 2020, we no longer have any derivative contracts.

The fair values of our revolving credit facility approximate carrying value due to the variable rate nature of these borrowings.

Note 9. Goodwill

Goodwill has historically been derived from the acquisition of ATRM in 2019, MD Office Solutions (“MD Office”) in 2015, and substantially all of the assets of Ultrascan, Inc. (“Ultrascan”) in 2007. Digirad Imaging Solutions, KBS and EBGL carry a goodwill balance of $1.7 million, $3.8 million and $4.0 million, respectively .

Changes in the carrying amount of goodwill for the years ended December 31, 2020 and 2019, by reportable segment, are as follows (in thousands):

	Diagnostic Services		Building and Construction		Total
Balance at December 31, 2018	$	1,745	$	—	$	1,745
Recognition of ATRM (1)	—		8,233		8,233
Balance at December 31, 2019	1,745		8,233		9,978
Impairment of EBGL	—		(436)		(436)
Balance at December 31, 2020	$	1,745	$	7,797	$	9,542

84

(1)On September 10, 2019, Star Equity, previously known as Digirad Corporation, completed its acquisition of ATRM pursuant to the ATRM Merger Agreement. The goodwill recognized is attributable primarily to expected synergies and the assembled workforce of KBS and EBGL. As the result, we allocated the goodwill to the two reporting units, KBS and EBGL, $3.8 million and $4.0 million, respectively. As of December 31, 2019, there was a subsequent measurement of goodwill and a related tax benefit adjustment that resulted in a net adjustment of $3.0 thousand to the recognized amounts of goodwill resulting from the acquisition.

During the fourth quarter of 2020, we performed a qualitative assessment for all reporting units to estimate whether it is more likely than not that the fair value of each reporting unit was less than its carrying amount. In performing this qualitative assessment, we assessed relevant events and circumstances that may impact the fair value and the carrying amount of each reporting unit. Factors that were considered included, but were not limited to, the following: (1) macroeconomic conditions; (2) industry and market conditions; (3) overall financial performance and expected financial performance; (4) other entity specific events. Based on the results of this qualitative assessment, we determined that it is more likely than not that all reporting units were not impaired, with the exception of our EBGL reporting unit.

The Company concluded that it was more likely than not that the carrying value of the EBGL reporting unit were in excess of fair value and therefore, updated its estimated fair value of these assets as of that date. This conclusion was based on lower than expected operating results during the year ended December 31, 2020, primarily as a result of higher commodity lumber price and COVID-19 impact. In performing the goodwill impairment assessment, we determined the fair value of the EBGL and KBS reporting units using both an income approach and a market approach. Under the income-based approach, we use a discounted cash flow model in which cash flows anticipated over several future periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate risk-adjusted rate of return. We use our internal forecasts to estimate future cash flows and include an estimate of long-term growth rates based on our most recent views of the long-term outlook. Actual results may differ materially from those used in our forecasts. The discount rate used in the discounted cash flow analysis reflects the risks inherent in the expected future cash flows. Determining fair value using a market approach considers multiples of financial metrics based on both acquisitions and trading multiples of a selected peer group of companies. From the comparable companies, a representative market multiple was determined which was applied to financial metrics to estimate the fair value. As a result, we recorded an impairment loss of $0.4 million associated with the impairment assessment of the EBGL reporting unit as of December 31, 2020 within Statement of Operations.

Estimating the fair value of the reporting units requires the use of estimates and significant judgments regarding future cash flows that are based on a number of factors including actual operating results, forecasted billings, revenue, and spend targets, discount rate assumptions, and long-term growth rate assumptions. These estimates and judgments could adversely change in future periods and we cannot provide absolute assurance that all of the targets will be achieved, which could lead to future impairment charges.

Sterling Credit Facility

On March 29, 2019, the Company entered into a Loan and Security Agreement (the “SNB Loan Agreement”) by and among certain subsidiaries of the Company, as borrowers (collectively, the “ SNB Borrowers”); the Company, as guarantor; and Sterling National Bank, a national banking association, as lender (“Sterling” or “SNB”).

The SNB Loan Agreement is a five-year credit facility maturing in March 2024, with a maximum credit amount of $20.0 million for revolving loans (the “SNB Credit Facility”). Under the SNB Credit Facility, the SNB Borrowers can request the issuance of letters of credit in an aggregate amount not to exceed $0.5 million at any one time outstanding. The borrowings under the SNB Loan Agreement were classified as short-term obligations under GAAP as the agreement contained a subjective acceleration clause and required a lockbox arrangement whereby all receipts are swept daily to reduce borrowings outstanding. As of December 31, 2020, the Company had $0.2 million of letters of credit outstanding and had additional borrowing capacity of $7.3 million.

At the Borrowers’ option, the SNB Credit Facility will bear interest at either (i) a Floating LIBOR Rate, as defined in the Loan Agreement, plus a margin of 2.50% per annum; or (ii) a Fixed LIBOR Rate, as defined in the Loan Agreement, plus a margin of 2.25% per annum. As our largest single debt outstanding, our floating rate on this facility at the end of 2020 was 2.64%.

The Company used a portion of the financing made available under the SNB Credit Facility to refinance and terminate, effective as of March 29, 2019, its previous credit facility with Comerica.

The SNB Loan Agreement includes certain representations, warranties of SNB Borrowers, as well as events of default and certain affirmative and negative covenants by the SNB Borrowers that are customary for loan agreements of this type. These covenants include restrictions on borrowings, investments and dispositions by SNB Borrowers, as well as limitations on the SNB Borrowers’ ability to make certain distributions. Upon the occurrence and during the continuation of an event of default under the SNB Loan Agreement, SNB may, among other things, declare the loans and all other obligations under the SNB Loan Agreement immediately due and payable and increase the interest rate at which loans and obligations under the SNB Loan Agreement bear interest. The SNB Credit Facility is secured by a first-priority security interest in substantially all of the assets of the Company and the SNB Borrowers and a pledge of all shares of the SNB Borrowers.

On March 29, 2019, in connection with the Company’s entry into the SNB Loan Agreement, Jeffery E. Eberwein, the Executive Chairman of the Company’s board of directors, entered into Limited Guaranty Agreement (the “SNB Eberwein Guaranty”) with SNB pursuant to which he guaranteed to SNB the prompt performance of all the Borrowers’ obligations to SNB under the SNB Loan Agreement, including the full payment of all indebtedness owing by Borrowers to SNB under or in connection with the SNB Loan Agreement and related SNB Credit Facility documents. Mr. Eberwein’s obligations under the SNB Eberwein Guaranty are limited in the aggregate to the amount of (a) $1.5 million, plus (b) reasonable costs and expenses of SNB incurred in connection with the SNB Eberwein Guaranty. Mr. Eberwein’s obligations under the SNB Eberwein Guaranty terminate upon the Company and Borrowers achieving certain milestones set forth therein.

In connection with the SNB Credit Facility, in the year ended December 31, 2019, the Company recognized a $0.2 million loss on extinguishment due to the write off of unamortized deferred financing costs associated with our prior revolving credit facility with Comerica.

At December 31, 2020 and 2019, the Company was in compliance with all covenants.

On February 1, 2021, we entered into an amendment to the SNB Loan Agreement, which is described in more detail in Note 19. Subsequent Events, within the notes to our accompanying consolidated financial statements.

ATRM Loan Agreements

As of December 31, 2020, ATRM had outstanding revolving lines of credit of approximately $3.1 million. Our debt through ATRM primarily included (i) $1.1 million principal outstanding on KBS’s $4.0 million revolving credit facility under a Loan and Security Agreement, dated February 23, 2016, (as amended, the “KBS Loan Agreement”), with Gerber Finance Inc. (“Gerber”) and (ii) $2.0 million principal outstanding on EBGL’s $3.0 million revolving credit facility under a Revolving Credit Loan Agreement, dated June 30, 2017 (as amended, the “Premier Loan Agreement”) with Premier Bank (“Premier”), net of an immaterial amount of unamortized financing fees. As of December 31, 2020, ATRM was at the maximum borrowing capacity under both revolving lines of credit, based on the inventory and accounts receivable on that day which fluctuates weekly.

See Note 16. Related Party Transactions, for information regarding certain ATRM promissory notes that are outstanding.

KBS Loan Agreement

On February 23, 2016, ATRM, KBS and Main Modular Haulers, Inc. (a subsidiary of ATRM) entered into a Loan and Security Agreement, (as amended, the “KBS Loan Agreement”), with Gerber. The KBS Loan Agreement provides KBS with a revolving line of credit with borrowing availability of up to $4.0 million. Availability under the line of credit is based on a formula tied to KBS’s eligible accounts receivable, inventory and other collateral. The KBS Loan Agreement, which was scheduled to expire on February 22, 2018, has been automatically extended for successive one (1) year periods in accordance with its terms and is now scheduled to expire on February 22, 2022. The KBS Loan Agreement will be automatically extended for another one (1) year period unless a party thereto provides prior written notice of termination. As of December 31, 2020, neither party has provided notice of termination. Upon the final expiration of the term of the KBS Loan Agreement, the outstanding principal balance is payable in full. Borrowings bear interest at the prime rate plus 2.75%, equating to 6.00% at December 31, 2020, with interest payable monthly. The KBS Loan Agreement also provides for certain fees payable to Gerber during its term, including a 1.5% annual facilities fee and a 0.10% monthly collateral monitoring fee. KBS’s obligations under the KBS Loan Agreement are secured by all of its assets and are guaranteed by ATRM. Unsecured promissory notes issued by KBS and ATRM are subordinate to KBS’s obligations under the KBS Loan Agreement. The KBS Loan Agreement contains representations, warranties, affirmative and negative covenants, defined events of default and other provisions customary for financings of this type. Financial covenants require that KBS maintain a maximum leverage ratio (as defined in the KBS Loan Agreement) and KBS not incur a net annual post-tax loss in any fiscal year during the term of the KBS Loan Agreement. The borrowings under the KBS Loan Agreement were classified as short-term obligations under GAAP as the agreement contained a subjective acceleration clause and required a lockbox arrangement whereby all receipts are swept daily to reduce borrowings outstanding. At December 31, 2020, approximately $1.1 million was outstanding under the KBS Loan Agreement.

The parties to the KBS Loan Agreement have amended the KBS Loan Agreement to provide for increased availability under the KBS Loan Agreement to KBS under certain circumstances, including for new equipment additions, and certain other changes, as well as a waiver of certain covenants.

As of December 31, 2020 and 2019, KBS was not in compliance with the financial covenants requiring no net annual post-tax loss for KBS or the minimum leverage ratio covenant as of 2020. The occurrence of any event of default under the KBS Loan Agreement may result in KBS’s obligations under the KBS Loan Agreement becoming immediately due and payable. In April 2019, June 2019, February 2020 and February 2021, we obtained a waiver from Gerber for these events.

On September 10, 2019, the parties of the KBS Loan Agreement entered into a Consent and Acknowledgment Agreement and Twelfth Amendment to Loan Agreement (the “Twelfth Amendment”), by and among Gerber, KBS, ATRM and the Company, pursuant to which the Company agreed to guarantee amounts borrowed by certain ATRM’s subsidiaries from Gerber. The Twelfth Amendment requires the Company to serve as an additional guarantor with the existing guarantor, ATRM, with respect to the payment, performance and discharge of each and every obligation of payment and performance by the borrowing subsidiaries with respect to the loans made by Gerber to them. The Twelfth Amendment also provides that upon payment in full of the EBGL Obligations (as defined therein), the amount of the Cash Collateral (as defined therein) will be reduced to $0.3 million. Additionally, ATRM had on deposit $0.2 million in a collateral account maintained with Gerber to secure the loans under the KBS Loan Agreement which was returned to ATRM in November 2019.

On January 31, 2020, the Company, ATRM, KBS and Gerber entered into a Thirteenth Amendment to Loan and Security Agreement (the “Thirteenth KBS Loan Amendment”) to amend the terms of the KBS Loan Agreement, in order to, among other things (a) amend the definitions of “Ancillary Credit Parties,” “Guarantor,” “Obligations,” and “Subordinated Lender” to address the obligations of the Star Borrowers, the EBGL Borrowers, the Star Credit Parties, and the EBGL Credit Parties under the Star Loan Agreement, EBGL Loan Agreement and the Subordination Agreements (each as defined below) to which they are a party and (b) add a new cross default provision.

On March 5, 2020, in connection with the First EBGL Amendment, Gerber, KBS, ATRM and the Company entered into a Consent and as a Fourteenth Amendment to Loan and Security Agreement that amended the KBS Loan Agreement (the “Consent and Fourteenth Amendment”). Under the terms of the Consent and Fourteenth Amendment, the parties thereto (and the subordinated creditors that consented thereto) consented to the First EBGL Amendment and agreed that cash collateral would no longer be part of the borrowing base and that the borrowing base would no longer be based on cash availability for purposes of the KBS Loan Agreement.

On April 1, 2020, Gerber and KBS entered into a Fifteenth Amendment to Loan Agreement (the “Fifteenth Amendment”) pursuant to which the “Minimum Average Monthly Loan Amount” under the KBS Loan Agreement was decreased to twenty-five percent (25%) of the Maximum Revolving Amount (as defined in the KBS Loan Agreement).

On January 5, 2021, Gerber and KBS entered into a Sixteenth Amendment to Loan Agreement (the “Sixteenth Amendment”). The Sixteenth Amendment changed certain definitions under the KBS Loan Agreement to increase the inventory assets against which funds can be borrowed.

On February 26, 2021 Gerber and KBS entered into a Seventeenth Amendment to Loan Agreement (the Seventeenth Amendment”). The Seventeenth Amendment provided the waiver to the 2020 covenant breach and amended the financial covenants. The financial covenants under the KBS Loan Agreement, as amended, provide that (i) KBS shall make no distribution, transfer, payment, advance, or contribution of cash or property which would constitute a restricted payment; (ii) KBS shall report annual post-tax net income at least equal to (a) $385 thousand for the trailing 6-month period ending June 30, 2021 and (b) $500 thousand for the trailing fiscal year end December 31, 2021; and (iii) a minimum EBITDA at June 30, 2021 of more than $880 thousand or at December 31, 2021 of more than $1.5 million.

EBGL Premier Note

On June 30, 2017, EdgeBuilder and Glenbrook (together, EBGL) entered into a Revolving Credit Loan Agreement (as amended, “the Premier Loan Agreement”) with Premier providing EBGL with a working capital line of credit of up to $3.0 million. The Premier Loan Agreement replaced the prior revolving credit facility under a loan and security agreement with Gerber (the “EBGL Loan Agreement”), which was terminated on the same date and all obligations of EBGL and ATRM in favor of Gerber in connection with the EBGL Loan Agreement were extinguished.

Availability under the Premier Loan Agreement is based on a formula tied to EBGL’s eligible accounts receivable, inventory and equipment, and borrowings bear interest at the prime rate plus 1.50%, with interest payable monthly and the outstanding principal balance payable upon expiration of the term of the Premier Loan Agreement. The Premier Loan Agreement also provides for certain fees payable to Premier during its term. The initial term of the Premier Loan Agreement was scheduled to expire on June 30, 2018, but was extended multiple times by Premier through January 31, 2023. The Premier Loan Agreement may be further extended from time to time at our request, subject to approval by Premier. EBGL’s obligations under the Premier Loan Agreement are secured by all of their inventory, equipment, accounts and other intangibles, fixtures and all proceeds of the foregoing.

On January 31, 2020, contemporaneously with the execution and delivery of the Star Loan Agreement and EBGL Loan Agreement described below, Glenbrook and EdgeBuilder entered into an Extension and Modification Agreement (the “Modification Agreement”) with Premier that modified the terms of the Revolving Credit Promissory Note (the “Premier Note”) made by Glenbrook and EdgeBuilder pursuant to the Premier Loan Agreement. Pursuant to the Modification Agreement, the amount of indebtedness evidenced by the Premier Note was reduced to $1.0 million, and the Premier Note was modified to, among other things: (a) extend the Final Maturity Date (as defined in the Premier Note) of the Premier Note to January 31, 2023, and (b) set the interest that the Premier Note will bear at 5.75% per annum. As a condition to close and to then later extend the term of the Premier Loan Agreement, ATRM and Mr. Eberwein executed a guaranty in favor of Premier, which has, through the multiple extensions described above, been extended through January 1, 2023, under which ATRM and Mr. Eberwein have absolutely and unconditionally guaranteed all of EBGL’s obligations under the Premier Loan Agreement. As of December 31, 2020, approximately $0.7 million was outstanding under the Premier Loan Agreement.

Gerber Star and EBGL Loans

On January 31, 2020, SRE, 947 Waterford Road, LLC (“947 Waterford”), 300 Park Street, LLC (“300 Park”), and 56 Mechanic Falls Road, LLC (“56 Mechanic” and together with SRE, 947 Waterford, and 300 Park, (the “Star Borrowers”), each an Investments Subsidiary, and the Company, ATRM, KBS, EdgeBuilder, and Glenbrook (collectively, the “Star Credit Parties”), entered into a Loan and Security Agreement (as amended, the “Star Loan Agreement”) with Gerber providing the Star Borrowers with a credit facility with borrowing availability of up to $2.5 million ($2.0 million and $0.5 million to KBS and EBGL, respectively) (the “Star Loan”). The advance of $2.0 million to KBS is to be repaid in monthly installments of sixty (60) consecutive equal payments. The advance of $0.5 million to EBGL, which has been temporarily increased by $0.3 million due to be repaid on April 30, 2020, is to be repaid in monthly installments of twelve (12) consecutive equal payments. On February 20, 2020, the Star Borrowers entered into a First Amendment to Loan and Security Agreement (the “First Star Amendment”) with Gerber that amended the Star Loan Agreement in order to (i) temporarily advance $0.3 million to EBGL, which amount is to be repaid to Gerber on or before April 30, 2020; (ii) clarify that Gerber can make multiple advances under the Star Loan Agreement, and (iii) to correct the maturity date of the Star Loan. On April 30, 2020, the Star Borrowers entered into a Second Amendment to Loan and Security Agreement (the “Second Star Amendment”) with Gerber that amended the Star Loan Agreement in order to change terms of repayment for the advance of $0.3 million to EBGL provided for under the First Star Amendment. Under the terms of the Second Star Amendment, the advance of $0.3 million to EBGL is to be repaid in three (3) consecutive equal monthly installments on the thirtieth (30th) day in each calendar month, commencing May 30, 2020, and in a final installment on or before July 31, 2020. As of September 30, 2020, EBGL repaid $0.3 million to Gerber. As of December 31, 2020, $1.6 million was outstanding under the Star Loan Agreement.

On January 31, 2020, EdgeBuilder and Glenbrook (the “EBGL Borrowers”), each a Construction Subsidiary, and the Company, Star, 947 Waterford, 300 Park, 56 Mechanic, ATRM, and KBS (collectively, the “EBGL Credit Parties”), entered into a Loan and Security Agreement (the “EBGL Loan Agreement”) with Gerber providing the EBGL Borrowers with a credit facility with borrowing availability of up to $3.0 million (the “EBGL Loan”). On March 5, 2020, the EBGL Borrowers entered into a First Amendment to Loan and Security Agreement (the “First EBGL Amendment”) with Gerber that amended the EBGL Loan Agreement and the KBS Loan Agreement in order to, among other things, include a pledge $0.3 million of cash collateral by LSVI under the EBGL Loan Agreement which, prior to the First EBGL Amendment, was pledged by LSVI in connection with the KBS Loan Agreement. On July 1, 2020, the EBGL Borrowers entered into a Second Amendment to Loan and Security Agreement that amended the EBGL Loan Agreement in order to, among other things, terminate the pledge of $0.3 million in cash collateral. On February 26, 2021, the EBGL Borrowers entered into a third amendment to the EBGL Loan Agreement (the “Third EBGL Amendment”) pursuant to which the Company and Gerber agreed to, among other things, eliminate the minimum leverage ratio covenant, lower the minimum EBITDA, and require the borrowers to not incur a net operating loss on bi-annual basis. The Third EBGL Amendment also discharged the EBGL Eberwein Guaranty described below. As of December 31, 2020, $2.0 million was outstanding under the Gerber EBGL revolving credit facility.

Availability under the Star Loan Agreement is based on a formula tied to the value of real estate owned by the Star Borrowers, and borrowings bear interest at the prime rate plus 3.5% per annum. Availability under the EBGL Loan Agreement is based on a formula tied to the EBGL Borrowers’ eligible accounts receivable and inventory, and borrowings bear interest at the prime rate plus 2.75% per annum. The Loan Agreements also provide for certain fees payable to Gerber during their respective terms. The Star Loan matures on the earlier of (a) January 1, 2025 or (b) the termination, the maturity or repayment of the EBGL Loan. The EBGL Loan matures on the earlier of (a) January 1, 2022, unless extended, or (b) the termination, the maturity or repayment of the Star Loan. The maturity of the EBGL Loan is automatically extended for successive periods of one (1) year each unless terminated by Gerber or the EBGL Borrowers. The borrowings under the EBGL Loan Agreement were classified as short-term obligations under GAAP as the agreement contained a subjective acceleration clause and required a lockbox arrangement whereby all receipts are swept daily to reduce borrowings outstanding.

The obligations of the EBGL Borrowers under the EBGL Loan Agreement are guaranteed by the EBGL Credit Parties and are secured by substantially all the assets of the EBGL Borrowers and the EBGL Credit Parties. The obligations of the Star Borrowers under the Star Loan Agreement are guaranteed by the Star Credit Parties and are secured by substantially all the assets of the Star Borrowers and the Star Credit Parties. Contemporaneously with the execution and delivery of the Star Loan Agreement, Jeffrey E. Eberwein, the Executive Chairman of the Company’s board of directors, executed and delivered a Guaranty (the “Gerber Eberwein Guaranty”) to Gerber pursuant to which he guaranteed the performance of all the Star Borrowers’ obligations to Gerber under the Star Loan Agreement, including the full payment of all indebtedness owing by the Star Borrowers to Gerber under or in connection with the Star Loan Agreement and related financing documents. Mr. Eberwein’s obligations under the Gerber Eberwein Guaranty are limited in the aggregate to the amount of (a) $2.5 million, plus (b) costs of Gerber incidental to the enforcement of the Gerber Eberwein Guaranty or any guaranteed obligations. On March 5, 2020, contemporaneously with the execution and delivery of the First EBGL Amendment, Mr. Eberwein, the Executive Chairman of the Company’s board of directors, executed and delivered a Guaranty (the “EBGL Eberwein Guaranty”) to Gerber pursuant to which he guaranteed the performance of all the EBGL Borrowers’ obligations to Gerber under the EBGL Loan Agreement, including the full payment of all indebtedness owing by the EBGL Borrowers to Gerber under or in connection with the EBGL Loan Agreement and related financing documents. Mr. Eberwein’s obligations under the EBGL Eberwein Guaranty are limited in the aggregate to the amount of (a) $0.5 million, plus (b) costs of Gerber incidental to the enforcement of the EBGL Eberwein Guaranty or any guaranteed obligations.

On February 26, 2021, the Star Borrowers entered into a third amendment to the Star Loan Agreement (the “Third Star Amendment”) with Gerber that, among other things, amended the contract rate to prime rate plus 3% and discharged the $2.5 million Gerber Eberwein Guaranty.

The Star Loan Agreement and EBGL Loan Agreement contains representations, warranties, affirmative and negative covenants, events of default and other provisions customary for financings of this type. The financial covenants under the EBGL Loan Agreement applicable to the EBGL Borrowers include maintenance of a minimum tangible net worth, a minimum debt service coverage ratio and minimum net income. The Financial covenants under the Star Loan Agreement applicable to the Star Borrowers include a minimum debt service coverage ratio. The occurrence of any event of default under the Loan Agreements may result in the obligations of the Borrowers becoming immediately due and payable. As of December 31, 2020, EBGL was not in compliance with the financial covenants under the Star Loan Agreement and EBGL Loan Agreement as of 2020. The occurrence of any event of default under the EBGL Loan Agreement may result in EBGL’s obligations under the EBGL Loan Agreement becoming immediately due and payable. In February 2021, we obtained a waiver from Gerber for these events and, as part of the Third EBGL Amendment (described above), the Company and Gerber agreed to, among other things, eliminate the minimum leverage ratio covenant, lower the minimum EBITDA, and require the borrowers to not incur a net operating loss on bi-annual basis, as well as discharge the EBGL Eberwein Guaranty.

As a condition to the extension of credit to the Star Borrowers and EBGL Borrowers under the Star Loan Agreement and EBGL Loan Agreement, the holders of certain existing unsecured promissory notes made by ATRM and certain of its subsidiaries entered into subordination agreements (the “Subordination Agreements”) with Gerber pursuant to which such noteholders (including the Company and certain of its subsidiaries) agreed to subordinate the obligations of ATRM and its subsidiaries to such noteholders to the obligations of the Star Borrowers and EBGL Borrowers to Gerber under the loan agreements.

Paycheck Protection Program

On April 30, 2020, each of KBS, EdgeBuilder and Glenbrook executed a separate promissory note evidencing unsecured loans under the Paycheck Protection Program (the “PPP”). The promissory note executed by KBS is for $0.8 million (the “KBS Note”), the promissory note executed by EdgeBuilder is for $0.2 million (the “EdgeBuilder Note”) and the promissory note executed by Glenbrook is for $0.2 million (the “Glenbrook Note”). The KBS Note, the EdgeBuilder Note and the Glenbrook Note, each dated April 30, 2020, are referred to together as the “Construction Notes”.

91

On May 11, 2020, the Company and each of Digirad Imaging Solutions, Inc. (“DIS”), DMS Imaging, Inc. (“DMS Imaging”) and DMS Health Technologies, Inc. (“DMS Health”), each a direct or indirect wholly owned subsidiary of the Company, executed a separate promissory note evidencing unsecured loans under the PPP. The promissory note executed by the Company, dated May 7, 2020, is for $0.8 million (the “Company Note”); the promissory note executed by DIS, dated May 5, 2020, is for $3.0 million (the “DIS Note”); the promissory note executed by DMS Imaging, dated May 5, 2020, is for $1.6 million (the “DMS Imaging Note”) and the promissory note executed by DMS Health, dated May 7, 2020, is for $0.1 million (the “DMS Health Note”). The Company Note, the DIS Note, the DMS Imaging Note, and the DMS Health Note are referred to together as the “Healthcare Notes”. The Construction Notes and the Healthcare Notes are referred to collectively as the “PPP Notes” and each promissory note individually as a “PPP Note”. As of December 31, 2020, the $1.6 million DMS Imaging Note, the $0.1 million DMS Health Note, and the $0.8 million Company Note were forgiven. In first quarter 2021, $0.4 million of the Glenbrook Note and EdgeBuilder Note, and $0.8 million of the KBS Note were forgiven; therefore, the DIS Loan is the only PPP Note that remains outstanding.

The PPP was established under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and is administered by the U.S. Small Business Administration (“SBA”). The loans evidenced by the Construction Notes are being made through Bremer Bank (“Bremer”) as lender, and the loans evidenced by the Healthcare Notes are being made through Sterling as lender.

The loans evidenced by the PPP Notes (the “PPP Loans”) have two-year terms and bear interest at a rate of 1.00% per annum. Monthly principal and interest payments under the PPP Loans are deferred for ten months after the end of covered periods. Beginning eleven months from the date of a PPP Note, unless fully forgiven prior thereto, the applicable borrower will pay to its lender thereunder a monthly principal and interest payments. The PPP Loans may be prepaid at any time prior to maturity with no prepayment penalties. The Construction Notes mature on April 30, 2022, and the Healthcare Notes mature two years from the date the loans under the Healthcare Notes are disbursed. Loans under the Company Note and the DIS Note were disbursed on May 12, 2020, and the loans under the DMS Health Note and DMS Imaging Note were disbursed on May 13, 2020.

The PPP Notes contain customary events of default relating to, among other things, payment defaults, making materially false and misleading representations to the SBA or lender, or breaching the terms of the applicable PPP Loan documents. Upon an event of default under a PPP Note, the lender thereunder may, among other things, require immediate payment of all amounts owing under the applicable PPP Note, collect all amounts owing from the applicable borrower, or file suit and obtain judgment.

Under the terms of the CARES Act, recipients of loans under the PPP can apply for and be granted forgiveness for all or a portion of the loan granted under the PPP. Such forgiveness will be determined, subject to limitations, based on the use of loan proceeds for payment of payroll costs and certain other eligible costs. However, no assurance is provided that forgiveness for any portion of the PPP Loans will be obtained and even if forgiveness is granted the PPP Loans may remain subject to review and audit due to all affiliated PPP Notes equaling more than $2 million.

In order to apply for the PPP Loans, we were required to certify, among other things, that the current economic uncertainty made the PPP Loans request necessary to support ongoing operations of the Company. This certification further required the Company to take into account its current business activity and its ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. The Company is continuing to evaluate the criteria and new guidance put out by the SBA regarding loan forgiveness and the procedures to seek loan forgiveness. As of December 31, 2020, $2.5 million of the Company Note, DMS Imaging Note and DMS Health Note were forgiven. Subsequently, Construction Notes were forgiven. The Company has sought full loan forgiveness from the SBA for the DIS Note, based on the satisfaction of applicable criteria and guidelines. PPP Loan forgiveness is sought under the belief that all entities requesting loan forgiveness have met the stated criteria and guidelines provided by the SBA and terms of the CARES Act; however, no assurance can be provided that forgiveness of the rest of PPP Loans will be obtained.

Note 11. Commitments and Contingencies

Other Matters

In the normal course of business, we have been, and will likely continue to be, subject to litigation or administrative proceedings incidental to our business, such as claims related to customer disputes, employment practices, wage and hour disputes, product liability, professional liability, commercial disputes, licensure restrictions or denials, and warranty or patent infringement. Responding to litigation or administrative proceedings, regardless of whether they have merit, can be expensive and disruptive to normal business operations. We are not able to predict the timing or outcome of these matters and do not expect that the resolution of these matters will have a material adverse effect on our financial position or results of operations.

Lessor

In the Digirad Health division, we generate lease income in the Diagnostic Services segment, from equipment rentals to customers. Rental contracts are structured as either a weekly or monthly payment arrangement and are accounted for as operating leases. Revenues are recognized on a straight-line basis over the term of the rental. As of December 31, 2020 and 2019, our lease contracts are mainly month to month contracts.

Within our Building and Construction segment, we subleased the manufacturing building located in Waterford, Maine to a commercial tenant pursuant to a lease with an initial 5 years term, commencing on September 6, 2019. The lease is structured with a monthly payment arrangement and is accounted for as an operating lease. As of December 31, 2020 our undiscounted cash flows for future minimum base rents to be received under operating leases from 2021 to 2024 are $0.1 million, $0.1 million, $0.2 million, and $0.1 million, respectively.

Note 13. Share-Based Compensation

At December 31, 2020, we have two active equity incentive plans, the 2011 Inducement Stock Incentive Plan (the “2011 Plan”), and the 2018 Incentive Plan (the “2018” Plan and together with the 2011 Plan, “the Plans”), under which stock options, restricted stock units, and other stock-based awards may be granted to employees and non-employees, including members of our Board of Directors. The terms of any equity instruments granted under the Plans are approved by the Board of Directors. Stock options typically vest over the requisite service period of one to 4 years and have a contractual term of seven to 10 years. Restricted stock units generally vest over one to 4 years. Under the Plans, we are authorized to issue an aggregate of 485,000 shares of common stock. As of December 31, 2020, the Plans had 368,334 shares available for future issuance. The number of shares reserved for issuance under the 2018 Plan is subject to increase by (i) the number of shares of common stock that remained available for grant under the 2014 Equity Incentive Award Plan (the “2014 Plan”) as of the effective date of the 2018 Plan, plus (ii) any shares of common stock under the 2014 Plan that are forfeited, expire, or are canceled. As of December 31, 2020, the number of shares provided for issuance under the 2018 Plan due to unissued, forfeited, expired, and canceled shares under the 2014 Plan was 59,620 shares.

Stock Options

The estimated fair value of our stock options is determined using the Black-Scholes model. All stock options were granted with an exercise price equal to the fair value of the common stock on the grant date. There were no employee stock options granted during the years ended December 31, 2020 and 2019.

Intraperiod allocation rules require us to allocate our provision for income taxes between continuing operations and other categories or comprehensive income (loss) such as discontinued operations. As described in Note 4. Discontinued Operations, the results of our Mobile Healthcare reportable segment have been reported as discontinued operations for the current and prior year. As a result of the intraperiod allocation rules, for the year ended December 31, 2020 and 2019, the Company recorded a tax expense of $22 thousand and a benefit of $0.1 million, respectively, for discontinued operations.

Differences between the provision for income taxes and income taxes at the statutory federal income tax rate for continuing operations are for the years ended December 31, 2020 and 2019 as follows:

Net deferred tax liabilities	$	(66)	$	(23)

The Company recognizes federal and state deferred tax assets or liabilities based on the Company’s estimate of future tax effects attributable to temporary differences and carryovers. The Company records a valuation allowance to reduce any deferred tax assets by the amount of any tax benefits that, based on available evidence and judgment, are not expected to be realized. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. The Company considers projected future taxable income and planning strategies in making this assessment. As of December 31, 2020, as a result of a three-year cumulative loss and recent events, we concluded that a full valuation allowance was necessary to offset our deferred tax assets. We intend to maintain a valuation allowance until sufficient positive evidence exists to support its reversal. The Company continues to be in a cumulative pretax loss for the three year period ended December 31, 2020. Accordingly, the full valuation allowance was maintained for the year ended December 31, 2020. The Company’s valuation allowance balance at December 31, 2020 is $18.9 million , offsetting the Company’s deferred tax assets. The Company will continue to evaluate its deferred tax balances to determine any assets that are more likely than not to be realized.

As of December 31, 2020, we had federal and state income tax net operating loss carryforwards after estimated section 382 limitations of $94.9 million and $108.8 million, respectively. Pre-2018 federal loss carryforwards will begin to expire in 2021 unless previously utilized. State loss carryforwards of approximately $0.2 million expired in 2020, and approximately $0.4 million is set to expire in 2021, unless previously utilized. We also have federal and California research and other credit carryforwards of approximately $0.7 million and $2.1 million, respectively, as of December 31, 2020. The federal credits will begin to expire in 2021. The California research credits have no expiration. Pursuant to Internal Revenue Code Sections 382 and 383, use of our net operating loss and credit carryforwards may be limited because of a cumulative change in ownership greater than 50%. As of December 31, 2020, the Company has not experienced a change in ownership greater than 50%; however, some of the tax attributes acquired with the DMS Health businesses are subject to such limitations due to ownership changes of greater than 50% that may have occurred or which may occur in the future. A valuation allowance has been recognized to offset the deferred tax assets, as realization of such assets has not met the “more likely than not” threshold required under the authoritative guidance of accounting for income taxes. In addition, the net operating losses acquired in the ATRM Acquisition are also limited under section 382.

98

The following table summarizes the activity related to our unrecognized tax benefits for the years ended December 31, 2020 and 2019 (in thousands):

	December 31,
	2020		2019
Balance at beginning of year	$	2,941	$	3,610
Expiration of the statute of limitations for the assessment of taxes	(163)		(669)
Balance at end of year	$	2,778	$	2,941

Included in the unrecognized tax benefits of $2.8 million at December 31, 2020 was $2.3 million of tax benefits that, if recognized, would reduce our annual effective tax rate, subject to the valuation allowance. The Company does not expect our unrecognized tax benefits to change significantly over the next 12 months.

We file income tax returns in the U.S. and in various state jurisdictions with varying statutes of limitations. We are no longer subject to income tax examination by tax authorities for years prior to 2016; however, our net operating loss carryforwards and research credit carryforwards arising prior to that year are subject to adjustment. Our policy is to recognize interest expense and penalties related to income tax matters as a component of income tax expense. The accrued interest as of December 31, 2020 and 2019, and interest and penalties recognized during the years ended December 31, 2020 and 2019 were of insignificant amounts.

Note 15. Employee Retirement Plan

Employees of the Company’s Digirad Health division have a 401(k) retirement plan under which employees may contribute up to 100% of their annual salary, within IRS limits. The Company contributions in continuing operations to the retirement plans totaled $0.2 million and $0.2 million for the years ended December 31, 2020 and 2019, respectively. The Company contributions in discontinued operations to the retirement plans totaled $0.1 million and $0.1 million for the years ended December 31, 2020 and 2019, respectively.

Cash contributions made by Mr. Eberwein subsequent to the ATRM Acquisition also exist as a payment due to Mr. Eberwein by ATRM. The LSVM Purchase Agreement contains representations, warranties, covenants and indemnification provisions customary for transactions of this type. LSVM was acquired by the Company as part of the ATRM Acquisition.

Financial Assistance

On May 1, 2019, the special committee of the Company’s board of directors (the “Special Committee”) approved financial assistance by the Company to ATRM, in the form of advances or cash payments on behalf of ATRM, in order assist ATRM in becoming current with its financial statements and filings with the SEC.

Joint Venture

On December 14, 2018, the Company and ATRM, entered into a joint venture and formed Star Procurement, LLC (“Star Procurement”), with the Company and ATRM each holding a 50% interest in Star Procurement.

KBS subleased the manufacturing building located in Waterford, Maine to North Country Steel Inc., a Maine corporation with an initial 5 year term rental agreement, commenced on September 6, 2019. The rental agreement is structured with a monthly payment arrangement and is accounted for as operating lease.

The base rental payments associated with the initial term under the Waterford Lease were estimated to be between $1.2 million and $1.3 million in the aggregate. The Park Lease had an initial term of 120 months, which is subject to extension. The base rental payments associated with the initial term under the Park Lease are estimated to be between $3.3 million and $3.6 million in the aggregate.

The initial term under the Oxford Lease commenced upon delivery of the Oxford Facility to KBS. The Oxford Lease had an initial term of 120 months, which is subject to extension. The base rental payments associated with the initial term under the Oxford Lease were estimated to be between $1.4 million and $1.5 million in the aggregate. ATRM had unconditionally guaranteed the performance of all obligations under the Oxford Lease to be performed by KBS, including, without limitation, the payment of all required rent.

As of September 10, 2019 and upon the completion of the ATRM Merger, the Waterford Lease, the Park Lease and the Oxford Lease are treated as intercompany transactions and eliminated in consolidation.

Note 17. Segments

Our business is organized into four reportable segments:

1.Diagnostic Services

2.Diagnostic Imaging

3.Building and Construction

4.Real Estate and Investments

For discussion purposes, we categorized our Diagnostic Services reportable segment as “Services,” and our Diagnostic Imaging reportable segment as “Product and Product-Related.”

Diagnostic Services. Through Diagnostic Services, the Company offers a convenient and economically efficient imaging and monitoring services program as an alternative to purchasing equipment or outsourcing the procedures to another physician or imaging center. For physicians who wish to perform nuclear imaging, echocardiography, vascular or general ultrasound tests, we provide imaging systems, qualified personnel, radiopharmaceuticals, licensing services, and the logistics required to perform imaging in their own offices, and thereby the ability to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for those services, which are primarily cardiac in nature. The Company provides imaging services primarily to cardiologists, internal medicine physicians, and family practice doctors who typically enter annual contracts for a set number of days ranging from once per month to five times per week.

Diagnostic Imaging. Through Diagnostic Imaging, the Company sells our internally developed solid-state gamma cameras, imaging systems and camera maintenance contracts. Our imaging systems include nuclear cardiac imaging systems, as well as general purpose nuclear imaging systems. We sell our imaging systems to physician offices and hospitals primarily in the United States, although we have sold a small number of imaging systems internationally.

Building and Construction. Through Star Equity’s wholly-owned subsidiaries KBS, Glenbrook and EdgeBuilder, we service residential and commercial construction projects by manufacturing modular housing units, structural wall panels, permanent wood foundation systems, other engineered wood products, and supply general contractors with building materials. KBS is a Maine-based manufacturer that started business in 2001 as a manufacturer of modular homes. KBS offers products for both commercial and residential buildings with a focus on customization to suit the project requirements and provide engineering and design expertise. Glenbrook is a retail supplier of lumber, windows, doors, cabinets, drywall, roofing, decking and other building materials and conducts its operations in Oakdale, Minnesota. EdgeBuilder is a manufacturer of structural wall panels, permanent wood foundation systems and other engineered wood products and conducts its operations in Prescott, Wisconsin.

Real Estate and Investments. Through this segment, we hold significant real estate assets that the Company acquires. As an initial transaction to create the Company’s real estate division under SRE in April 2019, the Company funded the initial purchase of three manufacturing facilities in Maine that manufacture modular buildings and leased those three properties. The funding of the assets acquisition was primarily through the revolver loan under our SNB Credit Facility. We also have an investment arm that operates under LSVM, which provides investment advisory services. We expect the investment advisory services to assist in making strategic investments, some of which may produce potential acquisition targets for the Company.

Our reporting segments have been determined based on the nature of the products and services offered to customers or the nature of their function in the organization. We evaluate performance based on the gross profit and operating income (loss) excluding litigation reserve expense, goodwill impairment, and transaction and integration costs. The Company does not identify or allocate its assets by operating segments. Accordingly, assets are not being reported by segment because the information is not available by segment and is not reviewed in the evaluation of performance or making decisions in the allocation of resources. Our operating costs included in our shared service functions primarily consist of senior executive officers, finance, human resources, legal, and information technology. During the fourth quarter of 2020, we have classified the results of our DMS segment as discontinued operations in our consolidated statement of operations for all periods presented. Accordingly, segment results have been recast for all periods presented to reflect DMS as discontinued operations. As costs of shared service functions previously allocated to DMS are not allocable to discontinued operations, prior period corporate costs have been reallocated amongst the continuing reportable segments.

ITEM 9A.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities and Exchange Commission Act of 1934 reports is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As further discussed below, we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on that evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were not effective as of December 31, 2020 as a result of the material weakness discussed below.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Because of its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Based on our evaluation under the framework in Internal Control—Integrated Framework (2013), our management concluded that our internal control over financial reporting was not effective as of December 31, 2020.

A “material weakness” is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

The Company identified material errors in the accounting for debt classification which resulted in the restatement of previously issued consolidated financial statements. These errors resulted from a material weakness related to ineffectively designed controls over review of contracts for new debt agreements and the proper application of GAAP for such agreements.

Plan for Remediation of the Material Weakness in Internal Control Over Financial Reporting

The Company has developed a remediation plan which includes, but is not limited to, a more detailed review over debt contracts and the proper application of GAAP.

Our internal controls over financial reporting are designed to provide reasonable assurance of achieving their objectives as specified above. Management does not expect, however, that our internal controls over financial reporting will prevent or detect all errors and fraud. Any internal control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.

Changes in Internal Control over Financial Reporting

Other than the material weakness described above in this Item 9A, there were no change in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rules 13a-15 or 15d-15 under the Securities Exchange Act of 1934 that occurred during fourth quarter of 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Our Board of Directors

Mr. Eberwein assumed the position of Executive Chairman of the Board of the Company on January 1, 2021, after serving as Chairman of the Board since February 6, 2013. As Executive Chairman, Mr. Eberwein became the Company’s principal executive officer. Mr. Eberwein is also the chairman of the board at Hudson, a global recruitment company. Mr. Eberwein has served as a director of Hudson since May 2014 and as its Chief Executive Officer since April 1, 2018. Mr. Eberwein is also the Chief Executive Officer of Lone Star Value Management, LLC (“LSVM”), a Connecticut based exempt reporting advisor and investment firm that Mr. Eberwein founded in 2013, of which certain funds it manages are winding down. LSVM was a wholly owned subsidiary of ATRM Holdings, Inc. (“ATRM”), a modular building company that was acquired by the Company on September 10, 2019 (the “ATRM Acquisition” or the “ATRM Merger”). Mr. Eberwein joined the board of directors of ATRM in January 2013 and became its chairman in November 2013.

We believe Mr. Eberwein’s expertise in finance and experience in the investment community, along with his extensive experience, qualifications, attributes and skills make him well qualified to serve as a director of our Company.

On February 14, 2017, the Securities and Exchange Commission (“SEC”) issued an order (Securities Exchange Act Release No. 80038) (the “Order”) relating to allegations that certain groups of investors failed to properly disclose ownership information during a series of five campaigns to influence or exert control over microcap companies. The Order alleged violations of Section 13(d)(1) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Rule 13d-1 thereunder, Section 13(d)(2) of the Exchange Act and Rule 13d-2(a) thereunder and Section 16(a) of the Exchange Act and Rules 16a-2 and 16a-3 thereunder by Mr. Eberwein and a hedge fund adviser headed by him, LSVM, a mutual fund adviser and another investor. Without admitting or denying the findings, they consented to the Order and agreed to cease and desist from committing any violations of the above-referenced Exchange Act provisions and civil penalties of $90 thousand for Mr. Eberwein, $120 thousand for LSVM, $180 thousand for the mutual fund advisor and $30 thousand for the other investor. On February 24, 2020, the SEC issued an order (Securities Exchange Act Release No. 5448) (the “Advisers Act Order”) relating to allegations, among other things, that LSVM failed to properly disclose certain specific transactions in advance and obtain client consent for these transaction prior to their completion and that LSVM failed to implement certain written policies and procedures. The Advisers Act Order alleged violations of Section 206(3) and 206(4) of the Investment Advisers Act of 1940 (“Advisers Act”) and Rule 206(4)-7 thereunder by Mr. Eberwein and LSVM. Without admitting or denying the findings, they consented to the Advisers Act Order and agreed to cease and desist from committing or causing any violations of the above-referenced Advisers Act provisions, for LSVM to be censured and to pay civil penalties of $25 thousand for Mr. Eberwein and $100 thousand for LSVM.

Matthew G. Molchan	Age: 54	Director since 2013
President and Chief Executive Officer of Digirad Health, Inc.

Committees: None

Mr. Molchan’s full biographical information is provided below under the heading “Our Executive Officers.”

We believe that Mr. Molchan’s extensive experience and key roles at a number of other companies having attributes similar to the Company, enable him to assist in the effective management of the Company and make him well qualified to serve on our Board of Directors.

Michael A. Cunnion	Age: 50	Director since 2014

Committees: Audit, Corporate Governance and Compensation (Chairman)

Mr. Cunnion has an extensive history of leadership roles at healthcare media and communication companies.

In addition, prior to that, from January 2004 to December 2007, Mr. Cunnion was the President of privately held HealthTalk, a leading provider of tools and information for chronically ill patients and caregivers. Mr. Cunnion successfully built this company and subsequently sold it to Revolution Health in December 2007.

We believe that Mr. Cunnion’s extensive experience with health care media companies, coupled with his experience with building up companies and creating ownership value are of significant strategic importance to us and make him well qualified to serve on our Board of Directors. His history of creating and leveraging collaborative relationships with the companies he has been part of to maximize value in both the continued organic growth and sale of such companies can be of great benefit to our stockholders.

Section 16(a) of the Exchange Act, requires the Company’s directors, executive officers, and holders of more than 10% of its common stock to file with the SEC reports regarding their ownership and changes in ownership of Digirad's securities.

Code of Business Ethics and Conduct

We have established a Code of Business Ethics and Conduct (the “Ethics Code”) that applies to all our officers, directors, employees, and contractors.

__________________

*Mr. Molchan resigned from his positions as President and Chief Executive Officer of the Company effective January 1, 2021, and assumed the additional position of Chief Executive Officer of Digirad Health Inc. effective that same day. Effective January 1, 2021, Mr. Eberwein assumed the position of Executive Chairman of the Board and as such became the Company’s principal executive officer.

(1)The base salary for each executive is initially established through negotiation at the time the executive is hired, taking into account his or her scope of responsibilities, qualifications, experience, prior salary, and competitive salary information within our industry. Year-to-year adjustments to each executive officer’s base salary are determined by an assessment of his or her sustained performance against individual goals, including leadership skills and the achievement of high ethical standards, the individual’s impact on our business and financial results, current salary in relation to the salary range designated for the job, experience, demonstrated potential for advancement, and an assessment against base salaries paid to executives for comparable jobs in the marketplace. Based on the factors discussed above, 2020 base salaries were: Mr. Molchan’s 2020 base salary was initially set at $415,200 from his last adjustment in February 2017, with a 20% reduction from April 6, 2020 to May 15, 2020, the total for 2020 was $405,619; Mr. Shirley’s 2020 base salary was initially set at $260,000 from his last adjustment in February 2017, with a 20% reduction from April 6, 2020 to May 15, 2020, the total for 2020 was $254,000; Mr. Noble’s 2020 base salary was set at $300,000, which represented no change from his 2018 base salary; with a 20% reduction from April 6, 2020 to May 15, 2020, the total for 2020 was $293,077. The differences between base and actual salary are due to pay period timing differences at year end.

(2)The 2020 Executive Incentive Plan for fiscal year ended December 31, 2020 (the “2020 Annual Plan”), which provides for discretionary bonuses, is described below in the Narrative Disclosure to Summary Compensation Table.

(3)Represents full fair value at grant date of restricted stock units (“RSUs”), including the PSUs described below, representing the right to receive, at settlement, common stock of the Company, granted to our named executive officers, computed in accordance with FASB ASC Topic 718, Stock Compensation. The full grant date fair value of an equity award is the maximum value that may be received over the vesting period if all vesting conditions are satisfied, as discussed further below. Thus, there is no assurance that the value, if any, eventually received by our executive officers will correspond to the amount shown. For information regarding assumptions made in connection with this valuation, please see Note 13. Share-Based Compensation to our accompanying consolidated financial statements.

115

(4)Represents the stock awards granted in 2019 as part of the Company’s executive incentive plan for that year (described below), were RSUs with performance conditions (PSUs), which vest ratably over two years subject to continued employment and achievement of the performance conditions for 2019 as determined by the Compensation Committee. No stock awards with performance conditions were granted in 2020 as part of the Company’s executive incentive plan for that year. The performance conditions for the 2019 PSUs were achieved at 100% of the Board approved budgeted EBITDA, excluding certain predetermined items, for the year ended December 31, 2019 and 2020, and the 2019 PSUs vested accordingly. The performance metrics for the 2019 performance period, and a grant date fair value for those tranches of the awards, were established by the Board and Compensation Committee on April 30, 2019. As of the grant date, the Company believed that it was probable that the performance criteria would be met and that each individual would remain employed through the date the grant would become fully vested by its terms, and accordingly, the full value of the awards as of the grant date has been included in the table above in accordance with FASB ASC 718. The performance conditions for 2019 were met. As such, the grant date fair values of the 2019 PSU awards were $0.1 million, and $0.07 million for Mr. Molchan and Mr. Shirley, respectively. The amount of PSUs vests in 2020 totaled 11,580 units. The RSU grant to Mr. Noble was made according to the terms of the Noble Employment Agreement (described below). The Company did not grant any stock awards to its named executive officers in 2020.

(5)Represents amounts earned under the Executive Incentive Plans of the Company with performance targets.

(6)Amounts shown for 2020 and 2019 include up to $2,500 matching contributions to the officers’ 401(k) retirement plans and up to $1,000 seed contribution to the executive’s Health Saving Account plans.

Narrative Disclosure to Summary Compensation Table.

Base Salary. The base salary for each executive is initially established through negotiation at the time the executive is hired, taking into account his or her scope of responsibilities, qualifications, experience, prior salary, and competitive salary information within the industry. Year-to-year adjustments to each executive officer’s base salary are determined by an assessment of his or her sustained performance against individual goals, including leadership skills and the achievement of high ethical standards, the individual’s impact on the Company’s business and financial results, current salary in relation to the salary range designated for the job, experience, demonstrated potential for advancement, and an assessment against base salaries paid to executives for comparable jobs in the marketplace.

When determining the base salary component of executive compensation for 2020, the Compensation Committee considered the achievements of the executives in 2019 based on actual financial performance of the business and achievement of the goals set by the Board of Directors for the individual executive, the fiscal 2020 budget and financial performance expectations, the totality of all compensation components. After due consideration, the Compensation Committee set compensation as reflected in the Summary Compensation Table above.

Annual Incentive Bonus. Payments under the Company’s executive bonus plan are based on achieving clearly defined, short-term goals, with the 2020 Annual Plan (described below) being the exception because it only provided for discretionary bonuses. We believe that such bonuses provide incentive to achieve goals that the Company aligns with its stockholders’ interests by measuring the achievement of these goals, whenever possible, in terms of revenue, income or other financial objectives. In setting bonus levels, the Company reviews its annual business plan and financial performance objectives. After estimating the likely financial results of the business plan as submitted by management and approved by the Board of Directors, the Company sets financial threshold goals based on those estimated results primarily in terms of EBITDA. The Company sets the minimum performance thresholds that must be reached before any bonus is paid at levels that will take significant effort and skill to achieve. An executive officer’s failure to meet some or all of these personal goals can affect his or her bonus amount. The Company believes that offering significant potential income in the form of bonuses allows the Company to attract and retain executives and to align their interests with those of the Company’s stockholders.

116

Fiscal Year 2020.

Due to the unprecedented and unpredictable nature of the COVID-19 pandemic, the Company’s executive team was pushed to new limits and was compelled to be creative, flexible, thoughtful, proactive and diligent in implementing decisions regarding the best way to meet the needs and expectations of our customers, our employees and our vendors, and our traditional bonus measures did not encompass or reward the effort being put forth during the pandemic. As a result, the 2020 Annual Plan was made 100% discretionary and based on subjective objectives to be determined by the Board. The actual cash bonuses payable (if any) for the achievement of such objectives was determined by the Compensation Committee.

The cash bonus amounts under the 2020 Annual Plan were as follows.

Name and Principal Position*	Percentage of Base Salary		Bonus Payout
David J. Noble, Chief Financial Officer and Chief Operating Officer	50	%	$	150,000
Martin B. Shirley, President, Digirad Imaging Solutions	25	%	$	65,000

*Mr. Molchan did not receive a discretionary cash bonus under the 2020 Annual Plan.

Equity Grants

The Company did not grant any stock awards to its named executive officers in 2020.

In connection with the adoption of the 2019 Executive Incentive Plan for fiscal year ended December 31, 2019 (the “2019 Annual Plan”), the Compensation Committee determined that, as part of a long-term retention mechanism and to incentivize the executive officers to increase the Company’s shareholder value, the following RSUs were awarded effective on May 15, 2019 (the “2019 Grant Date”), to Messrs. Molchan, Noble, and Shirley.

The RSUs granted to Messrs. Molchan and Shirley vest over two years in two equal installments, with each such installment vesting on each anniversary of the 2019 Grant Date, subject to satisfaction of certain 2019 performance criteria objectives. Each RSU grant to Messrs. Molchan and Shirley was made pursuant to and subject to the terms of the 2019 Annual Plan, the Company’s 2018 Incentive Plan, and the respective award agreement that sets forth the terms of the grant.

The RSU grant to Mr. Noble was made according to the terms of the Noble Employment Agreement (described below) and under the Company’s 2018 Incentive Plan. Mr. Noble’s RSU grant vests in three equal tranches. Mr. Noble did not receive an equity grants under the 2019 Annual Plan.

Name and Principal Position	Cash Value of the Restricted Stock Units Granted
Matthew G. Molchan, President and Chief Executive Officer of Digirad Health	$	103,800
David J. Noble, Chief Financial Officer and Chief Operating Officer	200,000
Martin B. Shirley, President, Digirad Imaging Solutions	65,000

Other Compensation

The Company currently maintains benefits for executive officers, that include medical, dental, vision and life insurance coverage and the ability to contribute to a 401(k) retirement plan; however, the Compensation Committee in its discretion may revise, amend or add to the officer's executive benefits if it deems it advisable. The benefits currently available to the executive officers are also available to other employees.

Potential Payments Upon Termination or Change of Control

Matthew G. Molchan

On May 1, 2007, the Company entered into an employment agreement with Mr. Molchan, which agreement was amended on September 30, 2010 (as amended, the “Molchan Employment Agreement”).

Pursuant to the Molchan Employment Agreement, Mr. Molchan can be terminated for “cause” or without “cause.” Under the Molchan Employment Agreement, termination for “cause” generally means the termination of Mr. Molchan’s employment by reason of: (i) willful misconduct or gross negligence in the performance of duties in the employment agreement; (ii) willful failure or refusal to perform in the usual manner at the usual time those duties which he regularly and routinely performs in connection with the Company’s business or such other duties reasonably related to the capacity in which he is employed which may be assigned to him if such failure or refusal has not been substantially cured; (iii) performance of any material action when specifically and reasonably instructed not to do; (iv) engaging or in any manner participating in any activity which is directly competitive with or intentionally injurious to the Company; (v) commission of any fraud, or unauthorized use or appropriation for his personal use or benefit of any funds, properties or opportunities of the Company; (vii) willful or grossly negligent violation of the Code of Ethics of the Company. Termination without “cause” means the termination of Mr. Molchan’s employment without “cause” at any time without liability for any reason not specified as a termination for “cause” upon not less than thirty (30) days written notice to Mr. Molchan.

Accordingly, if Mr. Molchan is terminated for “cause” before the last day of any calendar month, he would be entitled to receive compensation for such calendar month at his then current salary prorated to the date of termination on the basis of a 30-day calendar month. He would not be entitled to receive any severance payment. If Mr. Molchan is terminated without “cause,” he would be entitled to receive (i) his then current salary and the prorated amount of any accrued but unpaid performance bonus up to and including the date of termination, and (ii) a severance payment equal to six months of his then current salary.

If Mr. Molchan’s employment was terminated without “cause” as of December 31, 2020, Mr. Molchan would be entitled to receive $290,640.

Equity awards that would have vested upon termination or change of control at December 31, 2020, are described below under the heading “Equity Awards.”

David J. Noble

On October 31, 2018, the Company entered into an employment agreement with David J. Noble (the “Noble Employment Agreement”).

Pursuant to the Noble Employment Agreement, Mr. Noble can be terminated for “cause,” upon death, upon disability and without “cause.” Under the Noble Employment Agreement, termination for “cause” generally means the termination of Mr. Noble’s employment by reason of: (A) the willful failure of Mr. Noble to perform his duties and obligations in any material respect (other than any failure resulting from his disability), (B) intentional acts of dishonesty or willful misconduct by Mr. Noble with respect to the Company, (C) arrest or conviction of a felony or violation of any law involving dishonesty, disloyalty, moral turpitude, or fraud, or entry of a plea of guilty or nolo contendere to such charge, (D) Mr. Noble’s commission at any time of any act of fraud, embezzlement or willful misappropriation of material Company property, (E) repeated refusal to perform the reasonable and legal instructions of the Board, (F) willful and material breach of his obligations under any material agreement entered into between Mr. Noble and the Company or any of its affiliates, or willful and material breach of the Company’s polices or procedures which causes material damage to the Company, its business or reputation, provided that for subsections (A), (E), and (F), if the breach reasonably may be cured, Mr. Noble has been given at least thirty (30) days after his receipt of written notice of such breach from the Company to cure such breach. Termination without “cause” means termination for any reason other than death, disability, for “cause,” or for no reason at all, upon sixty (60) days’ written notice.

119

The Noble Employment Agreement provides for termination of Mr. Noble’s employment upon his election by voluntary resignation or termination for good reason. Termination by voluntary resignation means Mr. Noble can terminate his employment with the Company at any time and for any reason whatsoever or for no reason at all in his sole discretion upon giving sixty (60) days’ written notice. A termination for good reason means Mr. Noble can terminate his employment with the Company pursuant to the occurrence of any of the following events: (i) any material diminution in his authority, duties and responsibilities, (ii) any material reduction of his base salary, aggregate incentive compensation opportunities or aggregate benefits, unless such changes are applied to all members of the Company’s leadership team and amount to less than a 10% reduction in total, or (iii) a material breach by the Company of the Noble Employment Agreement. In addition, either the Company or Mr. Noble can deliver to the other party a written notice of non-renewal at least sixty (60) days prior to the applicable renewal date of the Noble Employment Agreement.

In the event Mr. Noble voluntarily resigns, is terminated for “cause,” is terminated upon death, or is terminated upon disability, he would be entitled to receive: (i) his then current salary accrued up to and including the date of termination or resignation, (ii) unreimbursed expenses, and (iii) any vested payment or accrued benefits under any equity or Company benefit plan (the “Accrued Obligations”). In March 2021, Mr. Noble agreed by letter that all future RSU awards under the Noble Employment Agreement would vest one-third on each of the first, second and third anniversaries of the grant date.

In the event Mr. Noble terminates his employment for good reason, his employment is terminated without “cause,” or his employment is terminated by delivery of a non-renewal notice by the Company, he would be entitled to receive: (i) the Accrued Obligations (described above), (ii) a target bonus based on the target bonus metrics used to determine actual performance at the end of the fiscal year, but prorated to reflect the number of full months worked during the fiscal year, (iii) immediate vesting of any RSUs awarded under the Noble Employment Agreement for which the performance period has not been completed as of the date of termination based on the level of achievement of the performance goals at the end of the performance period, but pro-rated based on the number of full months worked during the performance period, and (iv) immediate vesting of any RSUs awarded under the Noble Employment Agreement which are outstanding as of the date of termination. Notwithstanding the foregoing, if within twelve (12) months following a change of control (as defined in the Noble Employment Agreement), the Company terminates Mr. Noble’s employment without “cause,” he resigns from his employment with good reason, or his employment terminates due to Company’s delivery of a non-renewal notice, then the bonus payment under (ii) above shall equal the equivalent of his target bonus without proration and, in addition to (iii) and (iv) above, he shall receive (v) twelve months of his then-current base salary.

If Mr. Noble’s employment was terminated without “cause” as of December 31, 2020, he would have been entitled to receive: (i) a cash payment in the amount of $4,615, (ii) and immediate vesting of equity awards described below under the heading “Equity Awards.”

If Mr. Noble’s employment was terminated in connection with a change of control as of December 31, 2020, he would have been entitled to receive: (i) a cash payment in the amount of $300,000, (ii) and immediate vesting of equity awards described below under the heading “Equity Awards.”

Martin B. Shirley

On January 28, 2014, the Company entered into a severance agreement with Martin B. Shirley (the “Shirley Severance Agreement”). In the event his employment with the Company is terminated without “cause” (as defined below), he would receive a severance payment in an amount equal to six months of his base salary as in effect immediately prior to his termination date. In the event Mr. Shirley’s employment with the Company is terminated for “cause” or if he voluntarily terminates his employment with the Company, he will not be entitled to receive a severance payment. Assuming that Mr. Shirley’s employment was terminated without “cause” as of December 31, 2020, he would have been entitled to receive severance payments of $130,000.

Under the Shirley Severance Agreement, “cause” generally includes the occurrence of any of the following events: (i) the willful and deliberate failure to perform assigned duties or responsibilities to the Company or the lawful directions of his supervisor after notice from the Company describing his failure to perform such duties or responsibilities and a reasonable time to cure such failure; (ii) engaging in any act of dishonesty, fraud or misrepresentation in connection with his duties; (iii) a willful act constituting gross misconduct that is materially injurious to the Company; (iv) any act of embezzlement against the Company; (v) the breach of any confidentiality agreement or invention assignment agreement or any other written agreement with the Company; or (vi) his indictment for or conviction of, or entering a plea of nolo contendere to, a felony.

Equity awards that would have vested upon termination or change of control at December 31, 2020, are described below under the heading “Equity Awards.”

120

Equity Awards

The equity agreements of our named executive officers provide that, in case of a change of control of the Company, all equity instruments then outstanding but neither assumed nor replaced by the successor entity shall vest immediately upon the change of control event. Further, if an executive’s employment is terminated without cause within twelve (12) months of the change of control, all equity instruments then outstanding, either assumed or replaced, shall become fully vested at the time of termination. As of December 31, 2020, the value of the equity instruments of our named executive officers that would accelerate upon (i) termination without cause within twelve (12) months of a change of control in which stock options and restricted stock units are assumed or replaced by the successor entity, or (ii) a change of control in which the outstanding stock options and restricted stock units are neither assumed or replaced by the successor entity, would be as follows based on the difference between the closing price on the last trading day of the year of $3.59 per share and the exercise price of the respective options, and with regard to restricted stock units, based solely on the closing price on the last trading day of the year of $3.59:

Name	Option Value as of December 31, 2020		Stock Award Value as of December 31, 2020

David J. Noble	—		32,834
Martin B. Shirley	—		19,515

COMPENSATION OF DIRECTORS

Annual Retainer

Non-employee members of our Board of Directors are paid an annual retainer for their service, with additional compensation for being the chairperson of the Board, serving on a committee of the Board of Directors and chairing a committee of the Board of Directors. Payments are made quarterly.

The compensation paid to the members of the Board of Directors is indicated in the chart below:

2020 Director Cash Compensation
(1) Director Annual Retainer (all)	$	36,000
Additional Annual Retainer to Chairperson	$	15,000
Additional Annual Retainer to Audit Committee Chairperson	$	14,500
Additional Annual Retainer to Compensation Committee Chairperson	$	5,000
Additional Annual Retainer to Corporate Governance Committee Chairperson	$	5,000
(2) Additional Annual Retainer to Strategic Advisory Committee Chairperson	$	5,000
Additional Annual Retainer to Audit Committee Member	$	4,000
Additional Annual Retainer to Compensation Committee Member	$	4,000
Additional Annual Retainer to Corporate Governance Committee Member	$	4,000
(2) Additional Annual Retainer to Strategic Advisory Committee Member	$	4,000

(1)In April 2020, the Board of Directors elected to receive, all future payments of annual retainer amounts in Company RSUs in lieu of cash, the “Retainer Awards”. All other committee payments, committee chairmanship fees and Board chairmanship fees continue to be paid in cash for the remainder of 2020. In March 2021, the Compensation Committee of the Board elected that all directors receive all committee related compensation in the form RSUs, unless the director makes a timely one-time election to receive cash for the applicable year.

(2)The Strategic Advisory Committee was dissolved in April 2020.

For the sake of clarity, in fiscal year ended December 31, 2020, each of the Audit Committee, the Compensation Committee, the Corporate Governance Committee, and the Strategic Advisory Committee chairpersons only received an amount equal to the chairperson fee set forth in the table above and not the chairperson fee plus the member fee.

The single employee director of our Board of Directors, Mr. Molchan, the President and Chief Executive Officer of Digirad Health and our former President and Chief Executive Officer, does not receive additional compensation for his service on our Board of Directors.

121

Equity Compensation

Equity compensation awards, and the amount of such awards, to non-employee members of our Board are at the discretion of the Compensation Committee of our Board. Historically, such awards have been in the form of RSUs and the Compensation Committee generally set the amount of those awards at a fair market value equal to the annual cash retainer received by non-employee members of our Board. In April, 2020, the Compensation Committee approved the Board’s transition from quarterly cash retainer payments to quarterly equity awards for non-employee directors. In August, 2020, the Compensation Committee approved increasing the annual grant from 1,250 RSUs to 12,000 RSUs, with cliff vesting of one year from Grant Date, subject to the recipient continuing to be a service provider through vesting date and subject to Board approval of such grant. We believe that equity compensation helps to further align the interests of our directors with those of our stockholders because the value of directors’ share ownership will rise and fall with that of our other stockholders. In March 2021, the Compensation Committee of the Board elected to end the separate annual equity awards described above and to instead increase the size of the Retainer Awards to quarterly awards of RSUs having a fair market value (as defined in the 2018 Plan) of $18,000 each.

Director Compensation Table

Mr. Eberwein expressly disclaims beneficial ownership of such securities held in the Eberwein Trust except to the extent of his pecuniary interest therein. Mr. Eberwein, by virtue of his position as the manager and sole beneficial owner of LSV GP, the general partner of LSVI, may be deemed to beneficially own the securities owned by LSVI and LSV GP. Mr. Eberwein expressly disclaims beneficial ownership of such securities owned by LSVI and the securities owned by LSV GP, except to the extent of his pecuniary interest therein.

Private Placement

Immediately prior to the closing of the ATRM Merger, the Company issued 300,000 shares of Company Preferred Stock in a private placement (the “Private Placement”) to LSVI for a price of $10.00 per share for total proceeds to the Company of $3.0 million. The Private Placement was made pursuant to the terms of a Stock Purchase Agreement, dated as of September 10, 2019. The shares of Company Preferred Stock sold in the Private Placement have not been registered under the Securities Act of 1933, as amended (the “Act”), and may not be resold absent registration under, or exemption from registration under, the Act.

At the closing of the Private Placement, the Company and LSVI entered into a Registration Rights Agreement, dated as of September 10, 2019 (the “Registration Rights Agreement”), pursuant to which Digirad agreed to file a registration statement with the SEC, covering the resale of the shares of Company Preferred Stock issued in the Private Placement, if and upon the written request of the Private Placement investors at any time on or before September 10, 2021.

Director Independence

The Board has determined that each of Michael Cunnion, John Sayward and Mitchell Quain, a majority of the Board, satisfy the criteria for being an “independent director” under the independence standards of Nasdaq (as currently defined in Rule 5605(a)(2) of the NASDAQ rules) and has no material relationship with the Company other than by virtue of his service on the Board. Dimitrios Angelis, who served on the Board until the 2020 Annual Meeting, and John Climaco, who served on the Board until April 6, 2020, both satisfied the criteria for being an “independent director” under the independence standards of Nasdaq. In determining the independence of our directors, the Board of Directors considered all transactions in which the Company and any director had any interest, including those discussed above. The independent directors meet as often as necessary to fulfill their responsibilities, including meeting at least twice annually in executive session without the presence of non-independent directors and management. A full list of directors is set forth above under “ITEM 10. DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE – Our Board of Directors.”

The Audit Committee of the Board, established in accordance with Section 3(a)(58)(A) of the Exchange Act, currently consists of Messrs. Quain, Cunnion, and Sayward, with Mr. Sayward serving as chairman. All members of the Audit Committee are independent directors as defined in Rule 5605(a)(2) of the NASDAQ listing rules and Rule 10A-3 under the Exchange Act, and no member of the Audit Committee participated in the preparation of the financial statements of the Company or any current subsidiary of the Company at any time during the past three years. Prior to his resignation form the Board of Directors on April 6, 2020, Mr. Climaco served on the Audit Committee and was an independent director as defined in applicable Nasdaq rules and Rule 10A-3. Mr. Cunnion was appointed to the Audit Committee following Mr. Climaco’s resignation.

The Compensation Committee currently consists of Messrs. Quain, Sayward and Cunnion, with Mr. Cunnion serving as chairman. All members of the Compensation Committee are independent directors as determined in accordance with the Compensation Committee charter and applicable Nasdaq listing rules (Rule 5605(a)(2) of the NASDAQ listing rules).

All members of the Corporate Governance Committee are independent directors (as defined in Rule 5605(a)(2) of the NASDAQ listing rules). Mr. Eberwein, who served on the Corporate Governance Committee until July 21, 2020, was determined by the Board on April 17, 2020, to no longer be independent under the Nasdaq listing rules. Nasdaq Rule 5605(e)(3) permits one non-independent director to serve on the Corporate Governance Committee for a period of up to two years if the Board of Directors has determined that it is in the best interests of the Company and its shareholders. Our Board of Directors has determined that it is in the best interests of the Company and its shareholders for Mr. Eberwein to serve on the Corporate Governance Committee due to his finance expertise, extensive contacts and longtime experience with the Company.

Audit Committee Pre-Approval of Services by Independent Registered Public Accounting Firm

The Audit Committee is granted the authority and responsibility under its charter to pre-approve all audit and non-audit services provided to the Company by its independent registered public accounting firm, including specific approval of internal control and tax-related services. In exercising this responsibility, the Audit Committee considers whether the provision of each professional accounting service is compatible with maintaining the audit firm’s independence. The committee has delegated this pre-approval authority to the Chairperson of the Audit Committee with ratification by the full Audit Committee at its next scheduled meeting.

Pre-approvals are detailed as to the category or professional service and when appropriate are subject to budgetary limits. Company management and the independent registered public accounting firm periodically report to the Audit Committee regarding the scope and fees for professional services provided under the pre-approval.

With respect to the professional services rendered, the Audit Committee had determined that the rendering of all non-audit services by BDO was compatible with maintaining the auditor’s independence and had pre-approved all such services.
