Item 1. Business

Overview

MiMedx® is an integrated developer, manufacturer and marketer of patent protected regenerative biomaterial products and bioimplants processed from human amniotic membrane. “Innovations in Regenerative Biomaterials" is the framework behind our mission to provide physicians our products and tissues to help the body heal itself. Our biomaterial platform technologies include AmnioFix® and EpiFix®, our tissue technologies processed from human amniotic membrane that is derived from donated placentas. Through our donor program, mothers delivering full-term Cesarean section births can elect in advance of delivery to donate the placenta in lieu of having it discarded as medical waste. We process the human amniotic membrane utilizing our proprietary Purion® Process, to produce a safe and effective implant, which is referred to throughout this report as

an "allograft." MiMedx® is the leading supplier of amniotic tissue, having supplied hundreds of thousands of allografts to date for application in the Wound Care, Surgical, Sports Medicine, Ophthalmic and Dental sectors of healthcare.

Our History

Our current business began on February 8, 2008, when Alynx Co., our predecessor company, acquired MiMedx, Inc., a Florida-based, privately-held, development-stage medical device company (“MiMedx”), the assets of which included licenses to two development-stage medical device technology platforms- HydroFix® and CollaFix™.  On March 31, 2008, Alynx, Co. merged into MiMedx Group, Inc., a Florida corporation and wholly-owned subsidiary that had been formed on February 28, 2008, for purposes of the merger.  MiMedx Group, Inc. was the surviving corporation in the merger. In 2010, we commercialized the first medical device product using our HydroFix® technology. In 2011 and 2012, we launched additional versions of our HydroFix® product line.  In January 2011, the Company acquired all of the outstanding equity interests in Surgical Biologics, LLC (“Surgical Biologics”).  The acquisition of Surgical Biologics expanded our business by adding allografts and other products processed from human amniotic membrane to our existing medical device product lines based on our HydroFix® technology.  These tissue-based products represented approximately 96% of our revenues in 2011, and 99% of our revenues in 2012 and 2013. Also in 2013, we changed the name of Surgical Biologics to MiMedx Tissue Services, LLC. Due to the relatively small size of the addressable market for our HydroFix® product line, we decided to discontinue that product line in the fourth quarter of 2013. Although we have yet to commercialize any products using our CollaFix™ technology, we continue to believe that technology presents a significant opportunity in the orthopedic and sports medicine markets.

Our Technology and Products

AmnioFix®, EpiFix® and other Tissue -Based Allografts

MiMedx is the leading supplier of allografts processed from amniotic tissue, having supplied over 200,000 allografts to date for application in the Wound Care, Surgical, Sports Medicine, Ophthalmic, and Dental sectors of healthcare.  Our tissue-based products include our own brands, AmnioFix® and EpiFix®, as well as products that we supply on a private label or “OEM” basis.  We continue to research new opportunities for amniotic tissue, and currently have several additional offerings in various stages of conceptualization and development.

Amniotic membrane has been shown to lack certain antigens that elicit an immune response. Amniotic membrane is considered immunoprivileged.  Some dehydrated amniotic membranes include the epithelial layer, which studies have shown contributes significant immunosuppressive properties to dehydrated amniotic membrane products.

Natural human amniotic membrane is composed of multiple layers that contain:

• Structural proteins; including:

◦ Collagen types IV, V, and VII

◦ Elastin

• Specialized proteins; including:

◦ Fibrillin

◦ Fibronectin

◦ Laminins

◦ TIMPs 1,2,4, Tissue Inhibitor of Metalloproteinase 1, 2, 4

• Growth Factors; including but not limited to:

◦ Epidermal Growth Factor (EGF)

◦ Transforming Growth Factor Beta (TGF-B)

◦ Fibroblast Growth Factor (FGF)

◦ Platelet Derived Growth Factors A & B (PDGF A&B)

As discussed below under the subheading of “Tissue Processing and Recovery,” we believe our proprietary technique for processing allografts from amniotic tissue preserves more of the natural characteristics of the tissue than the processes used by our competitors.

Tissue Processing and Recovery

We operate a licensed tissue bank that is registered as an establishment with the United States Food and Drug Administration ("FDA").  We are an accredited member of the American Association of Tissue Banks (“AATB”).  We partner with physicians and hospitals to recover donated placental tissue.  After consent for donation is obtained, donors are screened for eligibility and the donated tissue is tested for safety in compliance with federal regulations and AATB standards on communicable disease transmission.  All donor records and test results are reviewed by our Medical Director prior to the release of the tissue for processing.

Over several years, we have developed a unique and proprietary technique for processing allografts from the donated placental tissue.  Our Purion® Process produces an allograft that is safe and effective. Our unique processing technique specifically focuses on maintaining the delicate structure and collagen matrix of the tissue.  The Purion® Process helps maintain graft structure, provides optimal performance and allows the allograft to be stored at room temperature and have a five-year shelf life.  Additionally, each allograft incorporates specialized visual embossments that assist the surgeon with proper graft placement and orientation.

Our team is dedicated to providing safe, superior allografts that exceed customer expectations.  To better satisfy the requirements and expectations of our customers, we maintain strict control on quality beginning at the time of procurement.  We have developed and implemented a Quality Management System in compliance with both FDA and AATB standards.  Using this Quality Management System, we maintain strict control over each step of the process.

EpiFix®

Our EpiFix® allograft is configured for external use. It is designed to enhance healing of wounds, as well as to reduce inflammation and scarring.  Currently, EpiFix® and EpiFix® Micronized are being used to treat chronic wounds, including diabetic foot ulcers, venous stasis ulcers, arterial ulcers and pressure ulcers, burns and surgical wounds (such as wounds following plastic surgery). We offer EpiFix® in a sheet form as well as a micronized powder form. The powder can be packed into wounds and is particularly useful for tunneling wounds. Some physicians also choose to mix the powder with saline to inject it into the wound bed and wound margins.

AmnioFix®

Our AmnioFix® allografts are configured for internal use.  Currently, our AmnioFix® product line consists of three configurations, AmnioFix®, AmnioFix® Wrap and AmnioFix® Injectable:

• AmnioFix® is provided in a sheet form.  It is configured to reduce inflammation, enhance non-structural soft tissue healing and to minimize scar tissue formation after primary surgical repair.  It is being used currently in spine, general and urology surgeries.

• AmnioFix® Wrap also is supplied in a sheet form and is configured for the same purposes as AmnioFix®, but is optimized for use as a “wrap” for nerves, tendons or ligaments.

• AmnioFix® Injectable is supplied in micronized powder form used for injection into soft tissue areas.  AmnioFix® is used to reduce inflammation while enhancing healing of soft tissue micro tears.  Currently, AmnioFix® is used to treat conditions such as: tendonitis, including plantar fasciitis, lateral epicondylitis, and medial epicondylitis; bursitis; strains and sprains.

Other Tissue Products

Currently, allografts for ophthalmic surgery and dental and oral maxilla facial applications are sold on an OEM basis pursuant to agreements whereby we have granted third parties exclusive licenses to some of our technology for use in those fields in specified markets.

Medical Device Technologies- CollaFix™ and HydroFix®

CollaFix™

Our CollaFix^™ technology combines an innovative means of creating fibers from soluble collagen and a specialized cross-linking process.  Initial laboratory and animal testing shows that the cross-linked collagen fibers produce a very strong, biocompatible, and durable construct that can be transformed into biomechanical constructs intended to treat a number of orthopedic soft-tissue trauma and disease disorders. The technology is licensed from Shriners Hospitals for Children and University of South Florida Research Foundation, Inc. pursuant to an exclusive, world-wide license to practice and use the technology and to manufacture, have manufactured, market, offer for sale and sell products incorporating the technology. The license of the technology is perpetual, except that the license terminates on a country-by-country basis as to any patent or portion thereof included in the licensed technology upon the expiration of such patent or portion thereof in the applicable country. We continue to evaluate how best to exploit this technology. We may license rights to specific aspects of our collagen technology to third parties for use in applications and indications that we choose not to exploit ourselves.

We are required to pay a royalty of 3% on all commercial sales revenue from the sale of products incorporating the licensed technology.  We also are obligated to pay a $50,000 minimum annual royalty payment over the life of the license.  

HydroFix®

Our HydroFix® products are based on licenses to certain patents and patent application rights to a PVA- based hydrogel, which is a water-based biomaterial that can be manufactured with a wide range of mechanical properties, including those that appear to mimic closely the mechanical and physical properties of natural, healthy human tissue. Because the addressable market for our HydroFix® products is somewhat limited, we chose to discontinue this product line in the fourth quarter of 2013. Currently, we have no plans to develop further products using the HydroFix® technology. Therefore, we no longer view that technology as material to our current or future business.  Our licenses to that technology are fully paid-up and we have no further obligations to the licensors under such licenses. See Note 2 to Consolidated Financial Statements “Significant Accounting Policies” under the subheadings “Impairment of Intangible Assets with Finite Lives” and “Impairment of Long-lived Assets.”

Intellectual Property

Our intellectual property includes licensed patents, owned and licensed patent applications and patents pending, proprietary manufacturing processes and trade secrets, and trademarks associated with our technology.  Furthermore, we require employees, consultants and advisors to sign Proprietary Information and Inventions Agreements, as well as Nondisclosure Agreements that assign to us and protect the intellectual property existing and generated from their work or that we may otherwise use or own. We believe that our patents, trade secrets, trademarks, and technology licensing rights provide us with important competitive advantages.

Of course, the pending patent applications may not result in issued patents and even if they do, the claims may be substantially modified or reduced.

See discussion below under “Risk Factors” “Risks Related to Our Intellectual Property.”

Market Overview

Our primary tissue allografts are comprised of dehydrated human amnion/chorion membrane (dHACM) that is processed using our proprietary Purion® Process. Our tissue-based products provide anti-inflammatory, anti-scarring and, in some cases, barrier properties, as well as enhanced healing at the surgical or wound site.  They can be stored at ambient temperature, with a five year shelf life and are easy for the physician to handle when treating a patient.

We currently are focused primarily on the U.S. market but may pursue specific individual international markets as opportunities arise.  In the U.S., the three key areas of focus for the products we market currently are chronic and acute wound care, surgical applications, where our products act as a barrier and minimize scar formation, and tendinopathy/ pain relief.

6

Acute and Chronic Wounds

An estimated 5.6 million patients have acute or chronic wounds¹. Our placental tissue-based allografts help heal acute and chronic wounds. Chronic wounds are defined as wounds that are delayed in closing compared to healing in an otherwise healthy individual.  Some of the most common types of chronic wounds are diabetic foot ulcers, venous leg ulcers, pressure ulcers, arterial ulcers, and surgical wounds that become infected. Acute wounds can be caused by surgical intervention, trauma or burns. For acute wounds, our tissue platforms have the potential to reduce scar tissue formation in a variety of applications, including the estimated 1.6 million patients annually undergoing elective aesthetic plastic surgery², as well the estimated 1.3 million patients annually undergoing Cesarean section births³, where scarring can limit flexibility, generate post-operative pain and can be unattractive. In both acute and chronic wounds, the physician’s goal during treatment is to heal the wound while allowing the patient to retain natural function in the area of the wound with minimal scarring and infection. If a wound becomes infected, it can lead to a loss of limb or life, and physicians want to close the wound as quickly as possible to minimize this risk. Patients with chronic wounds likely have comorbidities, such as diabetes or poor circulation, that complicate or delay the healing cascade.  According to the IData Research report US Market for Wound and Tissue Management for 2012, the market revenues in wound care are expected to rise at an accelerated compounded annual growth rate of 13.0% between 2011 and 2018. In addition, the report projects growth of skin substitute units of 10.3% in the same period to approximately 500,000 units⁴.

Our EpiFix® allografts, in both sheet and injectable forms, are used for the treatment of all types of chronic and acute, partial and full-thickness wounds.  EpiFix® delivers essential wound healing factors, extracellular matrix proteins and inflammatory mediators to help reduce inflammation, enhance healing, and reduce scar tissue formation.  Unlike some competing technologies, the use of EpiFix® is not limited to a specific wound. EpiFix® stores at ambient temperature (-80°- 80°C) for up to five years.  Certain cultured skin substitutes currently on the market require -80°C storage and expire only six months from time of processing.  Another leading skin substitute is delivered on demand and has strict temperature controls between 20° - 23° Celsius with a ten day shelf-life.  The logistics complications associated with the use of those products highlight the distinct advantages of EpiFix®.

In addition, our strategic plan to supply multiple sizes of grafts (from 1.5cm² to 49cm²) minimizes product waste.  Two leading competitors’ products come in only one size each, 2 inch x 3 inch (38 cm²) and 75 mm disc (42 cm²).  Since the majority of diabetic foot ulcers areless than 5cm², using one of these competitors’ products results in significant waste.

Surgical Applications

Our AmnioFix® tissue allografts have shown marked improvements in healing patients undergoing surgical procedures and helping to reduce scar tissue formation in a variety of applications including, but not limited to, plastic surgery, general surgery, OB/GYN, urology, orthopedics, spine, and sports medicine.

AmnioFix® is used as a barrier membrane in procedures where scar tissue formation may be problematic.  AmnioFix® provides additional benefits, including anti-inflammatory agents and growth factors, that may assist with soft tissue healing. A reduction of scar tissue is necessary if the patient needs to have an additional surgical procedure in the future, as it may facilitate the re-access to the surgical site, as well as help with scar attachment to the spinal dura.  There are approximately 850,000 spinal surgeries per year⁵ and most of them potentially could use AmnioFix® to reduce scarring and inflammation during the primary procedure, which may reduce time during reoperations or follow-up surgeries. AmnioFix® Wrap is applied by wrapping target tissues (ligaments, tendons, and or nerves) to create a barrier, which performs two functions: it acts as a neo-sheath to protect the target tissue and provides extracellular matrix proteins, cytokines and chemokines to enhance the wound healing process.

Tendinopathy and Pain

An estimated 17 million⁶ patients who have tendinopathy and pain associated with inflammation potentially could benefit from our AmnioFix® Injectable products. AmnioFix® Injectable addresses the chronic sports/work soft tissue injury market, including but not limited to tennis elbow, golfers elbow, plantar fasciitis, tendonitis, bursitis and sprains.  Soft tissue injuries are often caused by either trauma or overuse of the affected area.  Micro-tears in the tissue form and become inflamed. Scar tissue may form and impede a full recovery.  Steroids are often used as a first line to help the patient cope with the pain and assist with recovery.  There are a number of patients that do not get relief with steroids or do not want to use steroids, and over-use of steroids can cause long-term damage to the tissue.   AmnioFix® Injectable reduces inflammation and scar tissue formation, while enhancing healing of soft tissue micro-tears. We have demonstrated this clinical effectiveness through a Randomized Clinical Trial (RCT) examining the effects of AmnioFix® Injectable in the reduction of pain for plantar fasciitis. The study “Prospective, Randomized, Blinded, Comparative Study of Injectable Micronized Dehydrated Amniotic/Chorionic

Marketing and Sales

As of December 31, 2013, we had a direct sales force comprised of more than 70 sales professionals who call on hospitals, physicians, clinics and wound care centers. Some members of our sales force also call on government health care facilities, which order our products directly from our distributor for government accounts. We also have assembled a network of independent sales representatives and distributors to sell our surgical and sports medicine products.

We continue to pursue private label or “OEM” relationships, which allow us to leverage the sales and distribution resources of our private label customers. In the ophthalmic and dental markets, our products currently are marketed exclusively through a single licensee in each such field in specified markets. In October 2013, we entered into a non-exclusive distribution agreement with Medtronic, Inc. and its wholly-owned subsidiary, SpinalGraft Technologies, LLC (SGT). Under the agreement we will provide our Purion® Processed grafts to Medtronic to be marketed by SGT for spinal applications throughout the United States.

Reimbursement

In 2013, 56% of our products were purchased for government accounts, which do not depend on reimbursement from third parties.  With the exception of government accounts, most users of our products are doctors, hospitals or ambulatory surgery centers that rely on reimbursement by third-party payers.  Accordingly, our growth substantially depends on adequate levels of third-party reimbursement for our products from these payers. In the U.S., such payers include governmental programs (e.g., Medicare and Medicaid), private insurance plans, managed care programs and workers’ compensation plans.  Governmental payment programs have prescribed coverage criteria and reimbursement rates for medical products, services and procedures. Similarly, private third-party payers have their own coverage criteria and often have negotiated payment levels for medical products, services and procedures.  In addition, in the United States, an increasing percentage of insured individuals are receiving their medical care through managed care programs, which monitor and may require pre-approval of the products and services that a member will receive.

EpiFix® Sheet Products

Medicare Coverage

By far, the largest third party payer in the United States is the Medicare program, which is a federally funded program that provides healthcare coverage for senior citizens and the disabled. In addition, while, as discussed above, each payer has its own process and standards for determining whether it will cover and reimburse a procedure or particular product, private payers often follow the lead of governmental payers in making coverage and reimbursement determinations. Therefore, achieving favorable Medicare coverage and reimbursement is usually a significant gating factor for successful introduction of a new product.

The Medicare program is administered by the Centers for Medicare and Medicaid Services (CMS). CMS has appointed eight Medicare Administrative Contractors (MACs), which are private insurance companies that serve as agents of CMS in the

8

administration of the Medicare program, including the payment of claims and making coverage decisions for the Medicare-assigned jurisdiction for which they are responsible.

The coverage and reimbursement framework for products under Medicare is determined in accordance with the Social Security Act and pursuant to regulations promulgated by CMS, as well as the agency’s sub regulatory coverage and reimbursement determinations. Ultimately, however, each of the MACs determines whether and on what conditions they will provide coverage for the product. Such decisions are based on their assessments of the efficacy and cost effectiveness of the applicable product. As noted below under the heading “Research and Development,” we have devoted significant resources to clinical studies to be able to provide data to the MACs, as well as other payers, in order to demonstrate the efficacy and clinical effectiveness of our EpiFix® sheet products. As of the date of this report, seven of the eight MACs provided reimbursement for these products.

For Medicare reimbursement purposes, our EpiFix® sheet products are classified as “skin substitutes.” In 2013, providers that administered EpiFix® allografts and other skin substitutes were reimbursed for the products based on the size of the graft, computed on a per square centimeter basis. The payment rate was calculated using the manufacturer’s average sales price (“ASP”) information. We and other manufacturers of skin substitutes are required to provide ASP information to CMS on a quarterly basis. The Medicare payment rates are updated quarterly based on this ASP information. If a manufacturer is found to have made a misrepresentation in the reporting of ASP, such manufacturer is subject to civil monetary penalties of up to $10,000 for each misrepresentation for each day in which the misrepresentation was applied. For skin substitutes administered in the physician office, the Medicare payment rate, which is established by statute, is ASP plus 6%. For skin substitutes administered in the hospital outpatient and ambulatory surgery center setting, the statute establishes the payment rate for new drugs and biologicals that are granted “pass-through status” at the rate applicable in physicians’ offices (i.e., ASP plus 6%) for two to three years after the product is introduced. Our EpiFix® sheet allografts were granted pass-through status allowing reimbursement for EpiFix® sheet allografts administered in hospital outpatient departments and ambulatory surgery centers at ASP plus 6%. CMS establishes the payment rates for products administered in the hospital outpatient and ambulatory surgery setting that do not have pass-through status by regulation. For 2013, most skin substitutes were reimbursed at ASP plus 6%.

Beginning April 1, 2013, Medicare payments for all items and services, including EpiFix® sheet products, were reduced by 2% under the sequestration required by the Budget Control Act of 2011, Pub. L. No. 112-25, as amended by the American Taxpayer Relief Act of 2012, Pub. L. 112-240.

Our EpiFix® sheet allografts come in many sizes that are appropriate to the size of the wounds they are used to treat. Some competitive products come in only one size that is, on average, significantly larger than the wounds they are used to treat. The provider has to cut these products to size and the rest of the product is discarded, and, therefore, wasted. Because reimbursement for these products was based on the size of the graft, the Medicare payment for these grafts was costly, and a larger portion of the product was wasted. In part to combat this wastage, in November 2013, CMS announced a new reimbursement methodology for skin substitutes in the hospital outpatient and ambulatory surgical center setting effective in 2014. Under the new Hospital Outpatient Prospective Payment System (“OPPS”) Final Rule, CMS packages the reimbursement for skin care substitutes, including EpiFix®, with the related surgical procedure under a two-tier payment system. Under the new system, the Medicare packaged rate is not based on the size of the graft. Instead, the payment rate depends generally on the size of the wound to which the product is applied and whether the product is a “high cost skin substitute” or a “low cost skin substitute.” Skin substitutes with an average sales price amount above the weighted average of $32 per sq. cm. are classified in the high cost group and are reimbursed at a higher packaged rate; those at or below the weighted average per sq. cm. are classified in the low cost group and are reimbursed at a lower packaged rate. Because EpiFix® has pass-through status through 2014, in addition to the packaging payment, if the reimbursement for EpiFix® calculated on the basis of ASP plus 6% exceeds a specified “offset amount,” the facility will be entitled to an additional pass-through payment in the amount of the difference. The new CMS reimbursement policy does not apply to products applied in physician offices, which will continue to be reimbursed using the ASP plus 6% payment methodology. As discussed below under the heading "Competition", management believes this new methodology will provide us with opportunities to increase market share. Note that the payments for 2014 calculated as described above will continue to be reduced by 2% so long as sequestration remains in effect.

The methodology under which CMS establishes reimbursement rates is subject to further change, particularly because of budgetary pressures facing the Medicare program and the federal government.

We are devoting considerable resources to clinical trials to support coverage and reimbursement of our products and we are aware of an increasing number of private payers that are reimbursing for EpiFix® administered in the physician office or the hospital outpatient and ambulatory surgery center settings.   Even when a payer is convinced of the clinical and cost-effectiveness of our product, coverage and reimbursement may vary according to the individual or group plan or policy under

9

which the patient has coverage.  Therefore, we do not have reliable data as to how many commercial payers reimburse for EpiFix®, for which indications or at what rate.  We have established a reimbursement support group to educate and assist providers and patients with regard to reimbursement for our products.

Hospital Use

EpiFix® products administered in the hospital setting generally are bundled as part of the hospital’s bill for a diagnosis-related group (DRG).  In these cases, we also must convince the hospital that the product is both efficacious and cost-effective.

AmnioFix® Sheet Products

Our AmnioFix® surgical products generally are bundled as part of a hospital’s bill for a diagnosis-related group (DRG).  As noted above with respect to EpiFix®, the ability to sell products to the hospital market is dependent upon demonstrating to the hospital that the product is both efficacious and cost-effective.

EpiFix® and AmnioFix® Micronized Products

There currently is no third party reimbursement for our micronized products.

See discussion below- “Risk Factors” under the heading “Our revenues depend on adequate reimbursement from public and private insurers and health systems.”

Customer Concentration

We provide products to Government accounts, including the Veteran’s Administration, through a distributor relationship with AvKARE, Inc., which is a veteran-owned General Services Administration Federal Supply Schedule Contractor.  In 2013, sales to this distributor represented 56% of our revenues.  The distribution agreement has a term of three years ending in April 2015, and has the potential to be extended for three additional one year terms.  This distribution relationship is different than our other distribution relationships in that our direct sales force calls on Government accounts to generate orders for our products, which are placed directly with the distributor. Thus, if our agreement with this distributor was terminated for any reason, including because this distributor was no longer a Federal Supply Schedule Contractor, we believe we could retain or regain that business by contracting with another distributor to service these government accounts or becoming a General Services Administration Federal Supply Schedule Contractor ourselves. Nevertheless, any disruption in the inclusion of our products on the Federal Supply Schedule for any reason could materially and adversely affect our business, revenues and results of operations.

Another of our distributors represented an additional 10% of our total revenues in 2013.  Our current distribution agreement with this distributor has a three year term, expiring in November 2015.

See discussion below- “Risk Factors” under the heading “A significant portion of our revenues and accounts receivable come from a limited number of accounts.”

Competition

Competition in the regenerative medicine field is intense and subject to rapid technological change. Companies within the industry compete on the basis of product efficacy, pricing, and ease of handling/logistics. The availability of third party reimbursement for a product also is a competitive advantage.

We compete in three major areas of clinical treatment where regenerative biomaterials may be employed to reduce inflammation, enhance healing and reduce scar tissue formation: advanced wound care treatment, orthopedic/ spine surgery and sports medicine. The EpiFix® product line is promoted primarily for advanced wound healing, while the AmnioFix® products are positioned for surgical and sports medicine applications.

Advanced wound care therapies employ skin grafts to aid in wound healing in cases where the healing has stalled or stopped. The primary competitive products in this space include other amniotic membrane allografts, tissue-engineered living skin equivalents, and porcine- or bovine-derived collagen matrix products. In 2013, our main competitors were Shire, the manufacturer of Dermagraft, and Organogenesis, the manufacturer of Apligraf. Both of those products are tissue-engineered living skin equivalents that require special shipping and/or storage in freezers. Both of those products also come in only one large size, which is significantly larger than many of the wounds they are used to treat, resulting in a high cost product, much of which is wasted. In January 2014, Organogenesis announced that it was acquiring the rights to the Dermagraft product line. Although we have competed effectively against Dermagraft and Apligraf based on the clinical efficacy of and cost effectiveness

10

of our products and ease of storage and handling, we believe we will be able to compete even more effectively in 2014 due to the changes in Medicare reimbursement for skin substitutes in the hospital outpatient setting. As discussed above under the heading “Reimbursement,” in 2014, these competitors’ products used in the hospital outpatient setting will no longer be reimbursed on a per square centimeter basis. As a result, we believe hospital outpatient facilities will be motivated to use more cost-effective products, such as EpiFix®.

Smith & Nephew’s Oasis is the primary competitive product among the porcine- or bovine- derived collagen matrix products. As a collagen it can help with providing a matrix in the wound, however, it offers limited growth factors to enhance healing and due to the porcine origin may cause an immune response in the patient. Oasis is a low cost option and falls into a correlating low cost reimbursement category. It is stored at room temperature and has a 2 year shelf life. There are a number of competitors producing and/or distributing amniotic membrane allografts, but none is dominant and we believe that, currently, there is very limited reimbursement for their products.

The primary competitive products in the orthopedic/surgical market are other amniotic membrane allografts. Again, there are several competitors, but none is dominant.

In the sports medicine market, the primary competitive treatments are injections of the patient’s own platelet rich plasma (PRP) and steroidal cortisone injections. PRP is a time consuming process that involves drawing the patient’s blood, placing it in a centrifuge, spinning down the blood, extracting the platelet-rich portion, and then injecting the PRP back into the patient. Reimbursement for PRP is varied and may be very limited in some areas. The injectable dehydrated Human Amnion/Chorion Membrane allografts are simply mixed with saline and provide many more growth factors and other elements to reduce inflammation and scar tissue and enhance healing. Cortisone steroid injections are used as an anti-inflammatory. They work within a few days and last up to several weeks; however, the initial effect may be temporary and subsequent doses may not be as effective. Animal studies have shown that such treatments may weaken tendons and soften cartilage and that repeated injections multiply these effects. There are myriad providers of both platelet rich plasma services and steroidal cortisone.

Many of our products have short regulatory time frames and our competitors may be able to develop competitive products that are as or more effective than our products or that render our products and technologies less competitive or obsolete. We also may face competition in the future from other companies that are researching and developing competitive products. Current and future competition in our market may lead to pricing pressure, which could have a negative impact on the profitability of our business in the future.

See discussion below- “Risk Factors” under the heading “We are in a highly competitive and evolving field and face competition from large,well-established, tissue processors, and medical device manufacturers as well as new market entrants.”

Government Regulation

FDA Premarket Clearance and Approval Requirements

Tissue Products

Our EpiFix® and AmnioFix® products are derived from human tissue. Each of these products is offered in both a sheet form and in a micronized form. As discussed below, some tissue-based products are regulated solely under Section 361 of the Public Health Service Act as human cells, tissues and cellular and tissue-based products, or HCT/Ps, which do not require premarket clearance or approval by the FDA. Other tissue products are regulated as biologics and, in order to be lawfully marketed in the United States, require an FDA-approved biologics application (BLA).

Products Regulated as HCT/Ps

The FDA has specific regulations governing human cells, tissues and cellular and tissue-based products, or HCT/Ps. An HCT/P is a product containing or consisting of human cells or tissue intended for transplantation into a human patient. HCT/Ps that meet the criteria for regulation solely under Section 361 of the Public Health Service Act (so-called “361 HCT/Ps”) are not subject to any premarket clearance or approval requirements and are subject to less stringent post-market regulatory requirements.

To be a 361 HCT/P, a product generally must meet all four of the following criteria:

• It must be minimally manipulated;

• It must be intended for homologous use;

11

• Its manufacture must not involve combination with another article, except for water, crystalloids or a sterilizing, preserving or storage agent; and

• It must not have a systemic effect and must not be dependent upon the metabolic activity of living cells for its primary function.

If an HCT/P meets all the above criteria, no FDA review for safety and effectiveness under a drug, device, or biological product marketing application is required.

We believe that all of our tissue products qualify as 361 HCT/Ps. On August 28, 2013, however, the FDA issued an Untitled Letter alleging that our micronized allografts do not meet the minimal manipulation criteria for regulation solely under Section 361 of the Public Health Service Act due to the “micronization process which alters the original, relevant characteristics of the structural tissue, relating to the tissue’s utility for reconstruction, repair or replacement.” The Untitled Letter was published on the FDA’s website on September 4, 2013. In subsequent correspondence, the FDA asserted that the basis for its conclusion was that “[c]ryo-milling cut, dehydrated amniotic/chorionic membrane results in a micronized powder and the loss of the tensile strength and elasticity that are essential characteristics of the original amniotic/chorionic tissue relating to its utility to function as a ‘physical membrane’ (i.e. covering, barrier).” For this reason, the FDA believes that the micronized products are not eligible for marketing solely under Section 361 of the Public Health Service Act, but rather are biologics that can only be lawfully marketed if an approved biologics application (BLA) for the products is in effect. The process for obtaining an approved biologics application is described in more detail below.

We have advised the FDA that although we do not agree with their position, we understand the Agency’s interest in further regulating this emerging technology. Accordingly, we have proposed to the FDA that we will pursue the BLA process for certain micronized products, and, in parallel, also proposed to enter into negotiations with the FDA on a plan to transition the micronized products to licensed biological products and continue to market the micronized products under specific conditions. There is no guarantee that the FDA will agree to a transition plan or allow us to continue to market our micronized products while we pursue one or more BLAs. If they do allow us to continue to market our micronized products, they may impose conditions, such as labeling restrictions and compliance with Current Good Manufacturing Practices (“cGMP”). It is also possible that we will be required to recall our micronized products.

See discussion below- “Risk Factors” under the heading “To the extent our products do not qualify for regulation as human cells, tissues and cellular and tissue-based products under Section 361 of the Public Health Service Act, this could result in removal of the applicable products from the market, would make the introduction of new tissue products more expensive and significantly delay the expansion of our tissue product offerings and subject us to additional post-market regulatory requirements.”

Products Regulated as Biologics- The Biologics License Application (BLA) Pathway

The typical steps for obtaining FDA approval of a BLA to market a biologic product in the U.S. include:

• Completion of preclinical laboratory tests, animal studies and formulations studies under the FDA’s good laboratory practices regulations;

• Submission to the FDA of an Investigational New Drug Application (IND) for human clinical testing, which must become effective before human clinical trials may begin and which must include independent Institutional Review Board (IRB) approval at each clinical site before the trials may be initiated;

• Performance of adequate and well-controlled clinical trials in accordance with Good Clinical Practices to establish the safety and efficacy of the product for each indication;

• Submission to the FDA of a BLA for marketing the product, which includes, among other things, reports of the outcomes and full data sets of the clinical trials, and proposed labeling and packaging for the product;

• Satisfactory review of the contents of the BLA by the FDA, including the satisfactory resolution of any questions raised during the review;

• Satisfactory completion of an FDA Advisory Committee review, if applicable;

• Satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product is produced to assess compliance with Current Good Manufacturing Processes regulations, to assure that the facilities, methods and controls are adequate to ensure the product’s identity, strength, quality and purity; and

12

• FDA approval of the BLA, including agreement on post-marketing commitments, if applicable.

Generally, clinical trials are conducted in three phases, though the phases may overlap or be combined. Phase 1 trials typically involve a small number of healthy volunteers and are designed to provide information about the product safety and to evaluate the pattern of drug distribution and metabolism within the body. Phase 2 trials are conducted in a larger but limited group of patients afflicted with a particular disease or condition in order to determine preliminary efficacy, dosage tolerance and optimal dosing and to identify possible adverse effects and safety risks. Phase 3 clinical trials are generally large-scale, multi-center, comparative trials conducted with patients who have a particular disease or condition in order to provide statistically valid proof of efficacy, as well as safety and potency. In some cases, the FDA will require Phase 4, or post-marketing trials, to collect additional data after a product is on the market. All phases of clinical trials are subject to extensive record keeping, monitoring, auditing, and reporting requirements.

The process of obtaining an approved BLA requires the expenditure of substantial time, effort and financial resources and may take years to complete. The fee for filing a BLA and the annual user fees payable with respect to any establishment that manufactures biologics and with respect to each approved product are substantial. Additionally, there are significant costs associated with clinical trials that cannot be estimated until the IND is approved. Moreover, data obtained from clinical activities are not always conclusive and may be susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. The FDA may not grant approval on a timely basis, or at all. Additionally, the FDA may limit the indications for use or place other conditions on any approvals that could restrict the commercial application of the products. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing requirements and FDA review and approval.

See discussion below- “Risk Factors” under the heading “Obtaining and maintaining the necessary regulatory approvals for certain products will be expensive and time-consuming and may impede our ability to fully exploit our technologies.”

Medical Devices

We believe that any products produced from our HydroFix® and CollaFix^™ product platforms are likely to be classified by the FDA as medical devices.  Medical Devices are classed as I, II and III in the U.S., with Class II and III requiring either a 510(k) clearance or Premarket Approval (“PMA”) from the FDA prior to marketing. Devices deemed substantially equivalent to legally marketed devices are deemed to pose relatively less risk and are deemed Class II, which requires the manufacturer to submit a premarket notification requesting clearance for commercial distribution.  This is known as 510(k) clearance, which indicates that the device is substantially equivalent to devices already legally on the market.  Most Class I devices are considered very low risk and are exempted from this requirement.  Devices deemed by the FDA to pose the greatest risk, such as life-sustaining, life-supporting or devices deemed not substantially equivalent to a previously 510(k) cleared device or a pre-amendment Class III device for which PMA applications have not been required, are placed in Class III, requiring PMA. Although we may able to obtain approval for some products through the 510(k) clearance process, in order to fully exploit the CollaFix® technology, one or more PMA applications would be required.

Like the process of obtaining an approved BLA, the process of obtaining a PMA requires the expenditure of substantial time, effort and financial resources and may take years to complete. The FDA may not grant approval on a timely basis, or at all. Additionally, the FDA may limit the indications for use or place other conditions on any approvals that could restrict the commercial application of the products. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing requirements and FDA review and approval.

FDA Post Market Regulation

Tissue processors are required to register as an establishment with the FDA. As a registered establishment, we are required to comply with regulations regarding labeling, record keeping, donor eligibility, and screening and testing, process the tissue in accordance with established Good Tissue Practices, and report any adverse events and our facilities are subject to periodic inspections to assess our compliance with the regulations.

When and if we receive regulatory approval for a BLA for our injectable products or a PMA for a medical device incorporating our CollaFix® technology, we will be subject to numerous additional regulatory requirements, which include, among others, compliance with cGMP, which imposes certain procedural, substantive and record keeping requirements, labeling regulations, the FDA’s general prohibition against promoting products for unapproved or “off-label” uses, and more stringent adverse event reporting

13

The FDA has broad post-market and regulatory and enforcement powers.  If the FDA finds that we have failed to comply with the applicable requirements, it can institute a wide variety of enforcement actions, ranging from a warning letter to more severe sanctions such as:

•Fines, injunctions, and civil penalties;

•Recall or seizure of our products;

•Operating restrictions, partial suspension or total shutdown of production;

•Refusing our requests for clearance or approval of new products;

•Withdrawing or suspending current applications for approval or approvals already granted;

•Refusal to grant export approval for our products; and

•Criminal prosecution.

Other Regulation Specific to Tissue Products

We are accredited by the American Association of Tissue Banks (AATB), which has issued operating standards for tissue banking. Compliance with these standards is a requirement in order to become a licensed tissue bank.  In addition, some states have their own tissue banking regulations.

In addition, procurement of certain human organs and tissue for transplantation is subject to the restrictions of the National Organ Transplant Act (“NOTA”), which prohibits the transfer of certain human organs, including skin and related tissue for valuable consideration, but permits the reasonable payment associated with the removal, transportation, implantation, processing, preservation, quality control and storage of human tissue and skin.  We reimburse tissue banks, hospitals and physicians for their services associated with the recovery, storage and transportation of donated human tissue.  Although we have independent third party appraisals that confirm the reasonableness of the service fees we pay, if we were to be found to have violated NOTA’s prohibition on the sale or transfer of human tissue for valuable consideration, we would potentially be subject to criminal enforcement sanctions, which could materially and adversely affect our results of operations.

Fraud, Abuse and False Claims

We are directly and indirectly subject to various federal and state laws governing relationships with healthcare providers and pertaining to healthcare fraud and abuse, including anti-kickback laws.  In particular, the federal healthcare program Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing, arranging for or recommending a good or service for which payment may be made in whole or part under federal healthcare programs, such as the Medicare and Medicaid programs.  Penalties for violations include criminal penalties and civil sanctions such as fines, imprisonment and possible exclusion from Medicare, Medicaid and other federal healthcare programs.  The Anti-Kickback Statute is broad and prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry.  In implementing the statute, the Office of Inspector General of the U.S. Department of Health and Human Services (“OIG”) has issued a series of regulations, known as the “safe harbors.”  These safe harbors set forth provisions that, if all their applicable requirements are met, will assure healthcare providers and other parties that they will not be prosecuted under the Anti-Kickback Statute.  The failure of a transaction or arrangement to fit precisely within one or more safe harbors does not necessarily mean that it is illegal or that prosecution will be pursued.  However, conduct and business arrangements that do not fully satisfy each applicable element of a safe harbor may result in increased scrutiny by government enforcement authorities, such as the OIG.  Many states have laws similar to the federal law.

The Federal False Claims Act (“FCA”) imposes civil liability on any person or entity that submits, or causes the submission of, a false or fraudulent claim to the U.S. Government. Damages under the FCA can be significant and consist of the imposition of fines and penalties.  The FCA also allows a private individual or entity with knowledge of past or present fraud against the federal government to sue on behalf of the government to recover the civil penalties and treble damages.  The U.S. Department of Justice (“DOJ”) on behalf of the government has previously alleged that the marketing and promotional practices of pharmaceutical and medical device manufacturers including the off-label promotion of products or the payment of prohibited kickbacks to doctors violated the FCA resulting in the submission of improper claims to federal and state healthcare entitlement programs such as Medicaid.  In certain cases, manufacturers have entered into criminal and civil settlements with the federal government under which they entered into plea agreements, paid substantial monetary amounts and entered into corporate integrity agreements that require, among other things, substantial reporting and remedial actions going forward.

14

Healthcare fraud and abuse laws are complex, and even minor, inadvertent violations can give rise to claims that the relevant law has been violated.  We make payments to physicians and hospitals for a variety of services, such as tissue procurement services, research, serving on our medical advisory board, consulting, and speaking to payers about our products in support of our reimbursement efforts. While these transactions were structured with the intention of complying with all applicable laws, including state anti-referral laws and other applicable anti-kickback laws, it is possible that regulatory or enforcement agencies or courts may in the future view these transactions as prohibited arrangements that must be restructured or for which we would be subject to significant civil or criminal penalties.

AdvaMed is one of the primary voluntary U.S. trade associations for medical device manufacturers.  This association has established guidelines and protocols for medical device manufacturers in their relationships with healthcare professionals on matters including research and development, product training and education, grants and charitable contributions, support of third-party educational conferences, and consulting arrangements.  Adoption of the AdvaMed Code by a medical device manufacturer is voluntary, and while the OIG and other federal and state healthcare regulatory agencies encourage its adoption and may look to the AdvaMed Code, they do not view adoption of the AdvaMed Code as proof of compliance with applicable laws.  As part of a Company-wide compliance plan, we have incorporated the principles of the AdvaMed Code in our standard operating procedures, sales force training programs, and relationships with health care professionals. Key to the underlying principles of the AdvaMed Code is the need to focus the relationships between manufacturers and healthcare professionals on matters of training, education and scientific research, and limit payments between manufacturers and healthcare professionals to fair market value for legitimate services provided and payment of modest meal, travel and other expenses for a healthcare professional under limited circumstances.  We have incorporated these principles into our relationships with healthcare professionals under our consulting agreements, and our policies regarding payment of travel and lodging expenses, research and educational grant procedures and sponsorship of third-party conferences.  In addition, we have conducted training sessions on these principles. However, we cannot provide any assurance that regulatory or enforcement authorities will view these arrangements as being in compliance with applicable laws or that one or more of its employees or agents will not disregard the rules we have established.

See discussion below- “Risk Factors” under the heading “We and our sales representatives, whether employees or independent contractors, must complywith various federal and state anti-kickback, self-referral, false claims andsimilar laws, any breach of which could cause a material adverse effect on ourbusiness, financial condition and results of operations.”

Manufacturing (Processing)

In early 2014, we expanded our production capacity from one location in Kennesaw, Georgia, by adding a second and significantly larger, manufacturing facility within our headquarters building in Marietta, Georgia. In 2013, all processing was performed in the Kennesaw facility. Effective January 2014, processing was relocated to the Marietta, Georgia facility. The Kennesaw facility remains available as a secondary processing site.  We also perform research and early stage product and process development activities in its Marietta and Kennesaw, Georgia, locations.

We are subject to the FDA’s quality system regulations, state regulations, and regulations promulgated by the European Union.  We are FDA registered.  Our facilities are subject to periodic unannounced inspections by regulatory authorities, and may undergo compliance inspections conducted by the FDA and corresponding state and foreign agencies.

Suppliers

We have a comprehensive network of hospitals that participate in our placenta donation program.  We have a dedicated staff that works at these hospitals, collecting donated placentas from mothers who undergo Cesarean section births and consent to donation.  We believe that we will be able to procure an adequate supply of tissue to meet anticipated demand.

Research and Development

Our research and development group has extensive experience in developing products related to our field of interest, and works with our Medical Advisory Board to design products that are intended to improve patient outcomes, simplify techniques, shorten procedures, reduce hospitalization and rehabilitation times and, as a result, reduce costs.  Clinical trials that demonstrate the safety, efficacy and cost effectiveness of our products are key to obtaining broader reimbursement for our products.  In addition to our internal staff we contract with outside labs and physicians who aid us in our research and development process. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” at Item 7 below for information regarding expenditures for research and development in each of the last three fiscal years.

Environmental Matters

15

Our tissue preservation activities generate some chemical and biomedical wastes, consisting primarily of diluted alcohols and acids, human and animal pathological and biological wastes, including human and animal tissue and body fluids removed during laboratory procedures.  The chemical and biomedical wastes generated by our tissue processing operations are placed in appropriately constructed and labeled containers and are segregated from other wastes.  We contract with third parties for transport, treatment, and disposal of waste.  We strive to remain compliant with applicable laws and regulations promulgated by the Resource Conservation and Recovery Act, the U. S. Environmental Protection Agency and the Georgia Department of Natural Resources, Environmental Protection Division.

Employees

As of December 31, 2013, we had 222 employees.  We consider our relationships with our employees to be satisfactory.  None of our employees is covered by a collective bargaining agreement.

Litigation

Following the publication of the Untitled Letter from the FDA regarding our injectable products in September 2013, four purported class action lawsuits were filed against us and certain of our executive officers. Two of the lawsuits were filed in the U.S. District Court for the Southern District of New York on September 9, 2013, and September 10, 2013, respectively. The other two lawsuits were filed in the U.S. District Court for the Northern District of Georgia on September 13, 2013, and September 19, 2013, respectively.

Each complaint purports to be brought on behalf of shareholders who purchased our common stock during different time periods, beginning on various dates and all ending on September 4, 2013. The complaints generally allege that, during the differing class periods, all of the defendants violated Sections 10(b) of the Securities Exchange Act of 1934, or the Exchange Act, and SEC Rule 10b-5 and the individual defendants violated Section 20(a) of the Exchange Act in making various statements and alleged omissions related to our belief that FDA approval was not required to market our products, including our micronized products. The complaints seek unspecified damages, interest, attorneys’ fees, and other costs. We and our executive officers intend to vigorously defend against these lawsuits. These cases have now all been removed to, and consolidated in, the United States District Court for the Northern District of Georgia. By order dated December 9, 2013, the Court approved the appointment of a lead plaintiff and a lead counsel. A Consolidated Amended Class Action Complaint, containing substantially the same causes of action and claims for relief as the initial complaints, was filed on January 27, 2014. On February 26, 2014, we filed a Motion to Dismiss on various grounds. The plaintiffs' response to our Motion to Dismiss is due March 28, 2014. We currently believe that the outcome of this litigation will not have a material adverse impact on our financial position or results of operations.

Item 1A.   Risk Factors

Risks Related to Our Business and Industry

We have a history of net losses, and we may never achieve or maintain profitability.

We have incurred significant net losses over the last few years, including net losses of approximately $4.1 million in 2013, $7.7 million in 2012, $10.2 million in 2011, and $11.4 million in 2010. At December 31, 2013, we had an accumulated deficit of approximately $73.8 million.  We will continue to incur significant expenses for the foreseeable future as we expand our sales and marketing, research and development, and clinical activities and pursue regulatory approvals.  We may never generate sufficient revenues to achieve or sustain profitability.  Even if we do achieve profitability, we may not be able to sustain or increase profitability.  Our business and prospects must be evaluated in light of the expenses, delays, uncertainties and complications typically encountered by businesses in our stage of development operating in an evolving market. These include, but are not limited to, potential problems, delays or expenses relating to product development, governmental approvals or reimbursement for our products, competition, technological changes and uncertain market acceptance.  In addition, if we are unable to manage growth effectively, our operating results could be materially and adversely affected.  We may not be able to successfully control or address any or all of these risks, and the failure to adequately do so could cause our business, results of operations, and financial condition to suffer.

Our operating results may fluctuate significantly as a result of a variety offactors, many of which are outside of our control.

We are subject to the following factors, among others, that may negatively affect our operating results:

• The announcement or introduction of new products by our competitors;

• Failure of government and private health plans to adequately and timely reimburse the users of our products;

• Removal of our products from the Federal Supply Schedule or change in the prices that government accounts will pay for our products;

• Our ability to upgrade and develop our systems and infrastructure to accommodate growth;

• Our ability to attract and retain key personnel in a timely and cost effective manner;

• The amount and timing of operating costs and capital expenditures relating to the expansion of our business, operations and infrastructure;

• Regulation by federal, state or local governments; and

• General economic conditions as well as economic conditions specific to the healthcare industry.

As a result of our limited operating history, limited resources, the evolving nature of our products and the nature of the markets in which we compete, it is difficult for us to forecast accurately.  We have based our current and future expense levels largely on our investment plans and estimates of future events, although certain of our expense levels are, to a large extent, fixed. We may be unable to adjust spending in a timely manner to compensate for any unexpected revenue shortfall. Accordingly, any significant shortfall in revenue relative to our planned expenditures would have an immediate adverse effect on our business, results of operations and financial condition.  Further, as a strategic response to changes in the competitive environment, we may from time to time make certain pricing, service or marketing decisions that could have a material and adverse effect on our business, results of operations and financial condition.  Due to the foregoing factors, our revenue and operating results are and will remain difficult to forecast.

We are in a highly competitive and evolving field and face competition from large,well-established, tissue processors and medical device manufacturers, as well as new market entrants.

Our business is in a very competitive and evolving field. Competition from other tissue processors, medical device companies and from research and academic institutions is intense, expected to increase, subject to rapid change, and could be significantly affected by new product introductions.

Many of our products have short regulatory time frames and our competitors may be able to develop competitive products that are as or more effective than our products or that render our products and technologies less competitive or obsolete.

17

Many of our competitors have competitive advantages over us, including some or all of the following:

· Significantly greater name recognition;

· Established relations with surgeons, hospitals, other healthcare providers and third party payers;

· Large and established sales and distribution networks in the United States and/or in international markets;

· Greater experience in obtaining and maintaining regulatory approvals and/or clearances from the FDA and other regulatory agencies;

· Greater financial, managerial and other resources for product research and development, sales and marketing efforts and protecting and enforcing intellectual property rights.

The presence of this competition in our market may lead to pricing pressure, which would make it more difficult to sell our products at a price that will make us profitable or prevent us from selling our products at all.

Our success will depend on our ability to perfect and protect our intellectual property rights related to our technologies as well as to develop new technologies and new applications for our technologies.

Our failure to compete effectively would have a material and adverse effect on our business, results of operations and financial condition.

Our EpiFix® and AmnioFix® products are dependent on the availability of sufficient quantities of placental tissue from human donors, and any disruption in supply could adversely affect our business.

The success of our human tissue products depends upon, among other factors, the availability of sufficient quantities of placental tissue from human donors.  The availability of donated placental tissue could be adversely impacted by regulatory changes, public opinion of the donor process as well as our own reputation in the industry.  Any disruption in the supply of donated human tissue could restrict our growth and could have a material adverse impact on our business and financial condition.  We cannot be sure that the supply of human tissue will continue to be available at current levels or will be sufficient to meet our future needs.

Our EpiFix® and AmnioFix® products are derived from human tissue and therefore have the potential for disease transmission.

The utilization of human tissue creates the potential for transmission of communicable disease, including, but not limited to, human immunodeficiency virus (“HIV”), viral hepatitis, syphilis and other viral, fungal or bacterial pathogens.  We are required to comply with federal and state regulations intended to prevent communicable disease transmission.

Although we maintain strict quality controls over the procurement and processing of our tissue, there is no assurance that these quality controls will be adequate.  In addition, negative publicity concerning disease transmission from other companies' improperly processed donated tissue could have a negative impact on the demand for our EpiFix® and AmnioFix® products.

We depend on key personnel.

Our success will depend, in part, upon our ability to attract and retain skilled personnel, including sales, managerial and technical personnel.  There can be no assurance that we will be able to find and attract additional qualified employees to support our expected growth or retain any such personnel.  Our inability to hire and retain qualified personnel or the loss of services of our key personnel may have a material and adverse effect on our business, operations and results of operations.

In January 2012 the SEC brought a civil action against our Chairman and CEO alleging that in 2007, when he was Chairman and CEO of Matria Healthcare, Inc., Mr. Petit provided inside information to an individual who subsequently purchased Matria Healthcare stock, which the individual sold more than six months later for a gain of less than $10,000. Mr. Petit adamantly denies the allegations and is vigorously defending the action. Although a date has not yet been set, unless the case is dismissed, it is expected to be tried sometime in the first half of 2014. We are not involved in the litigation in any way. When the litigation was announced, our independent directors issued a press release announcing that they believed “Mr. Petit can continue his able leadership of MiMedx while dealing with this personal, civil matter.” One of the remedies sought in the litigation, however, is a bar prohibiting Mr. Petit from serving as an officer or director of a public company. Although we have in place a succession plan for Mr. Petit, as noted above, any transition in key personnel has the potential to negatively affect our business.

A significant portion of our revenues and accounts receivable come from a limited number of accounts.

Two customers accounted for approximately 66% of revenues for the year ended December 31, 2013.  We provide products to government accounts, including the Veteran's Administration, through a distributor that has a Federal Supply Schedule Contract that recently was extended through January 2018.  These sales represented 40% of our revenue in 2012 and 56% of our revenue in 2013.  Our agreement with the distributor has an initial term of three years ending in April 2015.  The agreement has the potential of being extended for three additional one year terms.  We believe the risk related to that concentration of revenue from a single distributor is mitigated by the fact that our own sales force calls on and has a personal relationship with the individual Veteran's Administration facilities that represent most of that revenue.  Therefore, we believe we eventually could regain much of the Veteran's Administration business, even if our relationship with our distributor were terminated.  Nevertheless, if our agreement with our distributor were terminated prematurely or if the distributor were for any reason unable to service the government market, there could be a disruption of our government accounts business that could materially and adversely affect our business, revenues and results of operations. Moreover, if our products were no longer on the Federal Supply Schedule (whether we are selling our products directly to government accounts or through our current or another distributor) or the government changed the way it purchased products like ours or the price it is willing to pay for our products, our business, revenues and results of operations could be materially and adversely affected.

Another of our distributors represented 10% of our revenue in 2013. 

As of December 31, 2013, the same two customers accounted for approximately 67% of total accounts receivable. This concentration of revenue and accounts receivable makes us more vulnerable to any credit risk associated with these two accounts.

In order to grow revenues from certain of our products, we must expand our relationships with distributors and independent sales representatives.

We derive material revenues through our relationships with distributors and independent sales representatives.  If such relationships were terminated for any reason, it could materially and adversely affect our ability to generate revenues and profits.  We intend to obtain the assistance of additional distributors and independent sales representatives to continue our sales growth with respect to certain of our products.  We may not be able to find additional distributors and independent sales representatives who will agree to market and/or distribute those products on commercially reasonable terms, if at all.  If we are unable to establish new distribution and independent sales representative relationships or renew current distribution and sales agency agreements on commercially acceptable terms, our business, financial condition and results of operations could be materially and adversely affected.

We are investing significant capital in expanding our internal sales force, and there can be no assurance that these efforts will result in significant increases in sales.

We are engaged in a major initiative to build and further expand our internal sales and marketing capabilities.  As a result, we are investing in a direct sales force for certain of our products to allow us to reach new customers.  These expenses impact our operating results, and there can be no assurance that we will be successful in significantly expanding the sales of our products.

Our revenues depend on adequate reimbursement from public and private insurers and health systems.

Our success depends on the extent to which reimbursement for the costs of our products and related treatments will be available from third party payers, such as public and private insurers and health systems.  Government and other third-party payers attempt to contain healthcare costs by limiting both coverage and the level of reimbursement of new products.  Therefore, significant uncertainty usually exists as to the reimbursement status of new healthcare products.  A significant number of public and private insurers and health systems currently do not provide reimbursement for our products.  If we are not successful in obtaining adequate reimbursement for our products from these third party payers, the market's acceptance of our products could be adversely affected.  Inadequate reimbursement levels also likely would create downward price pressure on our products.  Even if we do succeed in obtaining widespread reimbursement for our products, future changes in reimbursement policies could have a negative impact on our business, financial condition and results of operations.

Disruption of our processing could adversely affect our business, financialcondition and results of operations.

Our results of operations are dependent upon the continued operation of our processing facilities.  Risks that could impact our ability to use these facilities include the occurrence of natural and other disasters, and the need to comply with the

19

requirements of directives from government agencies, including the FDA.  The unavailability of our manufacturing and processing facilities could have a material adverse effect on our business, financial condition, and results of operations during the period of such unavailability.

To be commercially successful, we must convince physicians that our products aresafe and effective alternatives to existing treatments and that ourproducts should be used in their procedures.

We believe physicians will only adopt our products if they determine, based on experience, clinical data and published peer reviewed journal articles, that the use of our products in a particular procedure is a favorable alternative to conventional methods.  Physicians may be slow to change their medical treatment practices for the following reasons, among others: 

· Their lack of experience with prior procedures in the field using our products;

· Lack of evidence supporting additional patient benefits and our products over conventional methods;

· Perceived liability risks generally associated with the use of new products and procedures;

· Limited availability of reimbursement from third party payers; and

· The time that must be dedicated to training.

In addition, we believe recommendations for and support of our products by influential physicians are essential for market acceptance and adoption.  If we do not receive this support or if we are unable to demonstrate favorable long-term clinical data, physicians and hospitals may not use our products, which would significantly reduce our ability to achieve expected revenue and would prevent us from becoming profitable.

We will need to expand our organization, and we may be unable to manage rapid growth effectively.

Our failure to manage growth effectively could have a material and adverse effect on our business, results of operations and financial condition.  We anticipate that a period of significant expansion will be required to penetrate and service the market for our existing and anticipated future products and to continue to develop new products.  This expansion will place a significant strain on management, operational and financial resources.  To manage the expected growth of our operations and personnel, we must both modify our existing operational and financial systems, procedures and controls and implement new systems, procedures and controls.  We must also expand our finance, administrative, and operations staff.  Management may be unable to hire, train, retain, motivate and manage necessary personnel or to identify, manage and exploit existing and potential strategic relationships and market opportunities.

We face the risk of product liability claims and may not be able toobtain or maintain adequate product liability insurance.

Our business exposes us to the risk of product liability claims that are inherent in the manufacturing, processing and marketing of medical devices and human tissue products.  We may be subject to such claims if our products cause, or appear to have caused, an injury.  Claims may be made by patients, healthcare providers or others selling our products.  Defending a lawsuit, regardless of merit, could be costly, divert management attention and result in adverse publicity, which could result in the withdrawal of, or reduced acceptance of, our products in the market.

Although we have product liability insurance that we believe is adequate, this insurance is subject to deductibles and coverage limitations and we may not be able to maintain this insurance.  If we are unable to maintain product liability insurance at an acceptable cost or on acceptable terms with adequate coverage or otherwise protect ourselves against potential product liability claims, we could be exposed to significant liabilities, which may harm our business.  A product liability claim or other claim with respect to uninsured liabilities or for amounts in excess of insured liabilities could result in significant costs and significant harm to our business.

We may implement a product recall or voluntary market withdrawal, which could significantly increase our costs, damage our reputation and disrupt our business.

The manufacturing, marketing and processing of our tissue products involves an inherent risk that our tissue products or processes do not meet applicable quality standards and requirements.  In that event, we may voluntarily implement a recall or market withdrawal or may be required to do so by a regulatory authority.  A recall or market withdrawal of one of our products would be costly and would divert management resources.  A recall or withdrawal of one of our products, or a similar product processed by another entity, also could impair sales of our products as a result of confusion concerning the scope of the recall or withdrawal, or as a result of the damage to our reputation for quality and safety.

20

We may not be successful in commercializing our CollaFix™ Technology.

We have invested substantial time and resources in developing various additional products using our CollaFix™ technology.  Further commercialization of this technology will require additional development, clinical evaluation, regulatory clearance or approval, significant marketing efforts and substantial additional investment before they can provide us with any revenue.  Despite our efforts, any such products may not become commercially successful products for a number of reasons, including:

· We may not be able to obtain regulatory clearance or approvals for such products, or the approved indication may be narrower than we seek;

· Such products may not prove to be safe and effective in preclinical or clinical trials;

· Physicians or hospitals may not receive any reimbursement from third party payers, or the level of reimbursement may be insufficient to support widespread adoption of such products;

· We may experience delays in our development programs;

· Any products that are approved may not be accepted in the marketplace by physicians or patients;

· We may not be able to manufacture any such products in commercial quantities or at an acceptable cost; and

· Rapid technological change may make such products obsolete.

Risks Related to Our Intellectual Property

Our ability to protect our intellectual property and proprietary technologythrough patents and other means is uncertain and may be inadequate, which wouldhave a material and adverse effect on us.

Our success depends significantly on our ability to protect our proprietary rights to the technologies used in our products.  We rely on patent protection, as well as a combination of copyright, trade secret and trademark laws and nondisclosure, confidentiality and other contractual restrictions to protect our proprietary technology, including our licensed technology.  These legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitive advantage.  In addition, our pending patent applications include claims to material aspects of our products and procedures that are not currently protected by issued patents.  The patent application process can be time consuming and expensive.  We cannot ensure that any of our pending patent applications will result in issued patents.  Competitors may be able to design around our patents or develop products that provide outcomes that are comparable or even superior to ours.  Although we have taken steps to protect our intellectual property and proprietary technology, including entering into confidentiality agreements and intellectual property assignment agreements with some of our officers, employees, consultants and advisors, such agreements may not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements.  Furthermore, the laws of foreign countries may not protect our intellectual property rights to the same extent as do the laws of the United States.

The failure to obtain and maintain patents and/or protect our intellectual property rights could have a material and adverse effect on our business, results of operations, and financial condition.  Whether a patent is valid is a complex matter of science and law, and therefore we cannot be certain that, if challenged, our patents would be upheld.  If one or more of those patents are invalidated, that could reduce or eliminate any competitive advantage we might otherwise have had.

In the event a competitor infringes upon our licensed or pending patent or other intellectual property rights, enforcing those rights may be costly, uncertain, difficult and time consuming.

Even if successful, litigation to enforce or defend our intellectual property rights could be expensive and time consuming and could divert our management's attention.

The prosecution and enforcement of patents licensed to us by third parties arenot within our control, and without these technologies, our products may not besuccessful and our business would be harmed if the patents were infringed ormisappropriated without action by such third parties.

We have obtained licenses from third parties for patents and patent application rights related to our CollaFix™ technologies, allowing us to use intellectual property rights owned by or licensed to these third parties.  We do not control the maintenance, prosecution, enforcement or strategy for many of these patents or patent application rights and as such are

21

dependent in part on the owners of the intellectual property rights to maintain their viability.  Their failure to do so could significantly impair our ability to exploit those technologies.

We may become subject to claims of infringement of theintellectual property rights of others, which could prohibit us from developingour products, require us to obtain licenses from third parties or to developnon-infringing alternatives, and subject us to substantial monetary damages.

Third parties could assert that our products infringe their patents or other intellectual property rights.  Whether a product infringes a patent or other intellectual property involves complex legal and factual issues, the determination of which is often uncertain.  Therefore, we cannot be certain that we have not infringed the intellectual property rights of others.  Because patent applications may take years to issue, there also may be applications now pending of which we are unaware that may later result in issued patents that our products or processes infringe.  There also may be existing patents or pending patent applications of which we are unaware that our products or processes may inadvertently infringe.

Any infringement claim could cause us to incur significant costs, place significant strain on our financial resources, divert management's attention from our business and harm our reputation.  If the relevant patents in such claim were upheld as valid and enforceable and we were found to infringe, we could be prohibited from selling any product that is found to infringe unless we could obtain licenses to use the technology covered by the patent or other intellectual property or are able to design around the patent or other intellectual property.  We may be unable to obtain such a license on terms acceptable to us, if at all, and we may not be able to redesign our products to avoid infringement.  A court could also order us to pay compensatory damages for such infringement, plus prejudgment interest and could, in addition, treble the compensatory damages and award attorney fees. These damages could be substantial and could harm our reputation, business, financial condition and operating results.  A court also could enter orders that temporarily, preliminarily or permanently enjoin us and our customers from making, using, or selling products, and could enter an order mandating that we undertake certain remedial activities.  Depending on the nature of the relief ordered by the court, we could become liable for additional damages to third parties.

We may be subject to damages resulting from claims that we, our employees, orour independent contractors have wrongfully used or disclosed alleged tradesecrets of others.

Some of our employees were previously employed at other medical device or tissue companies. We may also hire additional employees who are currently employed at other medical device companies, including our competitors. Additionally, consultants or other independent agents with which we may contract may be or have been in a contractual arrangement with one or more of our competitors.  Although no claims against us are currently pending, we may be subject to claims that these employees or independent contractors have used or disclosed any party's trade secrets or other proprietary information. Litigation may be necessary to defend against these claims.  Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.  If we fail to defend such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel.  A loss of key personnel or their work product could hamper or prevent our ability to market existing or new products, which could severely harm our business.

Our NDGA License Agreement for our CollaFix™ technology could be terminated.

Under our license agreement with Shriners' Hospitals for Children and University of South Florida Research Foundation dated January 29, 2007, it is possible for the licensor to terminate the agreement if we breach the license agreement and all of our cure rights are exhausted.  If our license agreement were to be terminated, our investment in the technology would be lost.

Risks Related to Regulatory Approval of Our Products and Other GovernmentRegulations

To the extent our products do not qualify for regulation as human cells, tissues and cellular and tissue-based products under Section 361 of the Public Health Service Act, this could result in removal of the applicable products from the market, would make the introduction of new tissue products more expensive and significantly delay the expansion of our tissue product offerings and subject us to additional post-market regulatory requirements.

Our EpiFix® and AmnioFix® products are derived from human tissue.  The FDA has specific regulations governing human cells, tissues and cellular and tissue-based products, or HCT/Ps. An HCT/P is a product containing or consisting of human cells or tissue intended for transplantation into a human patient.  HCT/Ps that meet the criteria for regulation solely under Section 361 of the Public Health Service Act (so-called “361 HCT/Ps”) are not subject to any premarket clearance or approval requirements and are subject to less stringent post-market regulatory requirements.

To be a 361 HCT/P, a product generally must meet all four of the following criteria:

· It must be minimally manipulated;

22

· It must be intended for homologous use;

· Its manufacture must not involve combination with another article, except for water, crystalloids or a sterilizing, preserving or storage agent; and

· It must not have a systemic effect and must not be dependent upon the metabolic activity of living cells for its primary function.

Our position is that all of our tissue products are properly classified as 361 HCT/Ps. On August 28, 2013, however, the FDA issued an Untitled Letter alleging that our micronized allografts do not meet the minimal manipulation criteria for regulation solely under Section 361 of the Public Health Service Act due to the “micronization process which alters the original, relevant characteristics of the structural tissue, relating to the tissue’s utility for reconstruction, repair or replacement.” The FDA elaborated on the reasons for its conclusion in follow-up correspondence. Both the Untitled Letter and the follow-up correspondence from the FDA concluded that, as a result of the FDA’s determination, we would need a biologics license to lawfully market our micronized products. We have advised the FDA that although we do not agree with their position, we understand the agency’s interest in further regulating this emerging technology. Accordingly, we have proposed to the FDA that we will pursue the BLA process for certain micronized products, and, in parallel, also proposed to enter into negotiations with the FDA on a plan to transition the micronized products to licensed biological products and continue to market the micronized products under specific conditions. There is no guarantee that the FDA will agree to a transition plan or allow us to continue to market our micronized products while we pursue one or more BLAs. If they do allow us to continue to market our micronized products, they may impose conditions, such as labeling restrictions and compliance with Current Good Manufacturing Practices. It is also possible that we would have to recall products already on the market. Also, as discussed below, obtaining a biologics license requires substantial time, effort and financial resources and there is no assurance that any approvals for our injectable products will be granted on a timely basis, or at all. It is also possible that we would have to recall products already on the market.

Additionally, there can be no assurance that the FDA will not, at some future point, take the position that other current or future products do not qualify for regulation as 361 HCT/Ps and any regulatory reclassification could have adverse consequences for us and make it more difficult or expensive for us to conduct our business by requiring premarket clearance or approval and compliance with additional post-market regulatory requirements with respect to those products.

Moreover, increased regulatory scrutiny within the industry in which we operate could lead to increased regulation of HCT/Ps, including 361 HCT/Ps.  We also cannot assure you that the FDA will not impose more stringent definitions with respect to products that qualify as 361 HCT/Ps.

Obtaining and maintaining the necessary regulatory approvals for certain of our products will be expensive and time-consuming and may impede our ability to fully exploit our technologies.

The process of obtaining regulatory clearances or approvals to market a biologic or medical device from the FDA or similar regulatory authorities outside of the United States is costly and time consuming, and there can be no assurance that such clearances or approvals will be granted on a timely basis, or at all. As discussed above, we intend to pursue approval of a Biologics License Application (BLA) for certain of our micronized products. Additionally, the FDA may take the position that some of the other products that we currently market require a BLA as well. Some of the future products and enhancements to our current products that we expect to develop and market may require marketing clearance or approval from the FDA. There can be no assurance, however, that clearance or approval will be granted with respect to any of our products or enhancements or that FDA review will not involve delays that would adversely affect our ability to market such products or enhancements.

Our business is subject to continuing regulatory compliance by the FDA and other authorities, which is costly and our failure to comply could result in negative effects on our business.

As discussed above, the FDA has specific regulations governing our tissue-based products, or HCT/Ps.  The FDA's regulation of HCT/Ps includes requirements for registration and listing of products, donor screening and testing, processing and distribution (“Current Good Tissue Practices”), labeling, record keeping and adverse-event reporting, and inspection and enforcement.

Biologics and medical devices are subject to even more stringent regulation by the FDA. Even if pre-market clearance or approval is obtained, the approval or clearance may place substantial restrictions on the indications for which the product may be marketed or to whom it may be marketed, may require warnings to accompany the product or impose additional restrictions on the sale and/or use of the product.  In addition, regulatory approval is subject to continuing compliance with regulatory standards, including the FDA's quality system regulations.

23

If we fail to comply with the FDA regulations regarding our tissue products or medical devices, the FDA could take enforcement action, including, without limitation, any of the following sanctions and the manufacture of our products or processing of our tissue could be delayed or terminated:

• Untitled letters, warning letters, fines, injunctions, and civil penalties;

• Recall or seizure of our products;

• Operating restrictions, partial suspension or total shutdown of production;

• Refusing our requests for clearance or approval of new products;

• Withdrawing or suspending current applications for approval or approvals already granted;

• Refusal to grant export approval for our products; and

• Criminal prosecution.

It is likely that the FDA's regulation of our products will continue to evolve in the future.  Complying with any such new regulatory requirements may entail significant time delays and expense, which could have a material adverse effect on our business.

The American Association of Tissue Banks (“AATB”) has issued operating standards for tissue banking.  Compliance with these standards is a requirement in order to become a licensed tissue bank. In addition, some states have their own tissue banking regulations.

In addition, procurement of certain human organs and tissue for transplantation is subject to the restrictions of the National Organ Transplant Act (“NOTA”), which prohibits the transfer of certain human organs, including skin and related tissue for valuable consideration, but permits the reasonable payment associated with the removal, transportation, implantation, processing, preservation, quality control and storage of human tissue and skin.  We reimburse tissue banks, hospitals and physicians for their services associated with the recovery, storage and transportation of donated human tissue.  If we were to be found to have violated NOTA's prohibition on the sale or transfer of human tissue for valuable consideration, we would potentially be subject to criminal enforcement sanctions, which could materially and adversely affect our results of operations.

We and our sales representatives, whether employees or independent contractors, must comply with various federal and state anti-kickback, self-referral, false claims and similar laws, any breach of which could cause a material adverse effect on our business, financial condition and results of operations.

Our relationships with physicians, hospitals and other healthcare providers are subject to scrutiny under various federal anti-kickback, self-referral, false claims and similar laws, often referred to collectively as healthcare fraud and abuse laws.  Healthcare fraud and abuse laws are complex, and even minor, inadvertent violations can give rise to claims that the relevant law has been violated.  Possible sanctions for violation of these fraud and abuse laws include monetary fines, civil and criminal penalties, exclusion from federal and state healthcare programs, including Medicare, Medicaid, Veterans Administration health programs, workers' compensation programs and TRICARE (the healthcare system administered by or on behalf of the U.S. Department of Defense for uniformed services beneficiaries, including active duty and their dependents, retirees and their dependents), and forfeiture of amounts collected in violation of such prohibitions.  Certain states have similar fraud and abuse laws, imposing substantial penalties for violations.  Any government investigation or a finding of a violation of these laws would likely result in a material adverse effect on the market price of our common stock, as well as our business, financial condition and results of operations.

Anti-kickback laws and regulations prohibit any knowing and willful offer, payment, solicitation or receipt of any form of remuneration in return for the referral of an individual or the ordering or recommending of the use of a product or service for which payment may be made by Medicare, Medicaid or other government-sponsored healthcare programs.  We have formed a Medical Advisory Board consisting of an aggregate of over 14 physicians and scientists to assist us with scientific research and development and to help us evaluate technologies.  We have also entered into consulting agreements, speaker agreements, research agreements and product development agreements with physicians, including some who may order our products or make decisions to use them.  In addition, some of these physicians own our stock, which they purchased in arms' length transactions on terms identical to those offered to non-physicians, or received stock options from us as consideration for services performed by them.    While these transactions were structured with the intention of complying with all applicable laws, including state anti-referral laws and other applicable anti-kickback laws, it is possible that regulatory or enforcement agencies or courts may in the future view these transactions as prohibited arrangements that must be restructured or for which

24

we would be subject to other significant civil or criminal penalties.  Because our strategy relies on the involvement of physicians who consult with us on the design of our products, perform clinical research on our behalf or educate the market about the efficacy and uses of our products, we could be materially impacted if regulatory or enforcement agencies or courts interpret our financial relationships with physicians who refer or order our products to be in violation of applicable laws and determine that we would be unable to achieve compliance with such applicable laws.  This could harm our reputation and the reputations of the physicians we engage to provide services on our behalf.  In addition, the cost of noncompliance with these laws could be substantial since we could be subject to monetary fines and civil or criminal penalties, and we could also be excluded from federally funded healthcare programs, including Medicare and Medicaid, for non-compliance.

The scope and enforcement of all of these laws is uncertain and subject to rapid change, especially in light of the lack of applicable precedent and regulations.  There can be no assurance that federal or state regulatory or enforcement authorities will not investigate or challenge our current or future activities under these laws.  Any investigation or challenge could have a material adverse effect on our business, financial condition and results of operations.  Any state or federal regulatory or enforcement review of us, regardless of the outcome, would be costly and time consuming.  Additionally, we cannot predict the impact of any changes in these laws, whether these changes are retroactive or will have effect on a going-forward basis only.

We face significant uncertainty in the industry due to government healthcarereform.

There have been and continue to be proposals by the federal government, state governments, regulators and third party payers to control healthcare costs, and generally, to reform the healthcare system in the United States.  There are many programs and requirements for which the details have not yet been fully established or the consequences are not fully understood.  These proposals may affect aspects of our business.  We also cannot predict what further reform proposals, if any, will be adopted, when they will be adopted, or what impact they may have on us.

Risks Related to the Securities Markets and Ownership of Our Common Stock

The price of our common stock has been, and will likely continue to be,volatile.

The market price of our common stock, like that of the securities of many other companies that are in, or are just emerging from, the development stage, has fluctuated over a wide range and it is likely that the price of our common stock will fluctuate in the future.  From January 1, 2011, through December 31, 2013, the closing price of our common stock has fluctuated from a low of $.76 to a high of $8.74. The market price of our common stock could be impacted by a variety of factors, including:

· Fluctuations in stock market prices and trading volumes of similar companies or of the markets generally;

· Our ability to successfully launch, market and earn significant revenue from our products;

· Our ability to obtain additional financing to support our continuing operations;

· Disclosure of the details and results of regulatory applications and proceedings;

· Changes in government regulations or our failure to comply with any such regulations;

· Additions or departures of key personnel;

· Our investments in research and development or other corporate resources;

· Announcements of technological innovations or new commercial products by us or our competitors;

· Developments in the patents or other proprietary rights owned or licensed by us or our competitors;

· The timing of new product introductions;

· Actual or anticipated fluctuations in our operating results, including any restatements of previously reported results;

· Our ability to effectively and consistently manufacture our products and avoid costs associated with the recall of defective or potentially defective products;

· Our ability and the ability of our distribution partners to market and sell our products;

· Changes in reimbursement for our products or the price for our products to our customers;

25

· Removal of our products from the Federal Supply Schedule, or changes in how government accounts purchase products such as ours or in the price for our products to government accounts; and

. The other risks detailed in this Item 1A.

Further, due to the relatively fixed nature of most of our costs, which primarily include personnel costs as well as facilities costs, any unanticipated shortfall in revenue in any fiscal quarter would have an adverse effect on our results of operations in that quarter.  Accordingly, our operating results for any particular quarter may not be indicative of results for future periods and should not be relied upon as an indication of our future performance.  These fluctuations could cause the trading price of our stock to be negatively affected. Our quarterly operating results have varied substantially in the past and may vary substantially in the future.  In addition, the stock market has been very volatile in the recent past.  This volatility is often not related to the operating performance of companies listed thereon and will probably continue in the foreseeable future.

The concentrated common stock ownership by certain of our executive officers and directors will limit your ability to influence corporate matters.

As of December 31, 2013, our directors and executive officers together beneficially owned approximately 11% of our outstanding common stock.  This group has significant influence over our management and affairs and overall matters requiring shareholder approval, including the election of directors and significant corporate transactions, such as a merger or sale of our company or our assets, for the foreseeable future.  This concentrated control will limit the ability of other shareholders to influence corporate matters and, as a result, we may take actions that some of its shareholders do not view as beneficial.  In addition, such concentrated control could discourage others from initiating changes of control.  As a result, the market price of our shares could be adversely affected.

The exercise of warrants or options may depress our stock price and may result in dilution to our common stockholders.

There are a significant number of outstanding options and warrants to purchase our stock. If the market price of our common stock rises above the exercise price of outstanding warrants and options, holders of those securities may be likely to exercise their warrants and options and sell the common stock acquired upon exercise in the open market. Sales of a substantial number of shares of our common stock in the public market by holders of warrants and options may depress the prevailing market price for our common stock and could impair our ability to raise capital through the future sale of our equity securities.  Additionally, if the holders of outstanding options and warrants exercise those options or warrants, our common stockholders will incur dilution in their relative percentage ownership.

As of December 31, 2013, warrants to purchase 1,284,816 shares of our common stock at a weighted average exercise price of $0.90 per share were outstanding and exercisable; options to purchase 15,375,960 shares of common stock were outstanding, at a weighted average exercise price of $2.46 per share, of which 6,807,732 were exercisable at a weighted average exercise price of $1.33 per share.

Our common stock may be thinly traded.

At times the public market for our common stock has been minimal. We cannot be certain more of a public market for our common stock will continue to develop, or if developed, that it will be sustained.  Our common stock will likely be thinly traded compared to larger more widely known companies.  We cannot predict the extent to which an active public market for our common stock will develop or be sustained at any time in the future.  If we are unable to develop or sustain a market for our common stock, investors may be unable to sell the common stock they own, and may lose the entire value of their investment.

Securities analysts may elect not to report on our common stock or may issue negative reports that adversely affect the stock price.

At this time, four securities analysts provide research coverage of our common stock.  However, there is no assurance that these analysts will continue to report on our common stock or that additional analysts will initiate reporting on our common stock.  Rules mandated by the Sarbanes-Oxley Act and a global settlement reached in 2003 among the SEC, other regulatory agencies, and a number of investment banks led to a number of fundamental changes in how analysts are reviewed and compensated.  In particular, many investment banking firms are required to contract with independent financial analysts for their stock research.  It may remain difficult for a company such as ours, with a smaller market capitalization, to attract independent financial analysts that will cover our common stock. If securities analysts discontinue covering our common stock, the lack of research coverage may adversely affect its actual and potential market price.  The trading market for our common stock may be affected in part by the research and reports that industry or financial analysts publish about our business.  If one

26

or more analysts elect to cover us and then downgrade the stock, the stock price would likely decline rapidly.  If one or more of these analysts cease coverage of us, we could lose visibility in the market, which in turn could cause our stock price to decline.  This could have a negative effect on the market price of our shares.

We do not intend to pay cash dividends.

We have never declared or paid cash dividends on our capital stock. We currently expect to use available funds and any future earnings in the development, operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future.  In addition, the terms of any future debt or credit facility we may obtain may preclude us from paying any dividends.  As a result, capital appreciation, if any, of our common stock will be an investor's only source of potential gain from our common stock for the foreseeable future.

We and certain of our executive officers have been named as defendants in recently initiated class action lawsuits that could result in substantial costs and divert management’s attention.

We, and certain of our executive officers, have been named as defendants in purported class action lawsuits that allege violations of federal securities laws related to various statements regarding our belief that FDA approval was not required to market our products, including our micronized products. We intend to engage in a vigorous defense of such litigation.

In addition, the volatility in our stock price may make us more vulnerable to future class action litigation.

Any adverse judgment in or settlement of the pending or any future litigation could require payments that exceed the limits of our available directors’ and officers’ liability insurance, which could have a material adverse effect on our operating results or financial condition.

Provisions of Florida law and anti-takeover provisions in our organizational documents may discourage or prevent a change of control, even if an acquisition would be beneficial to shareholders, which could affect our share price adversely and prevent attempts by shareholders to remove current management.

We are subject to the Florida affiliated transactions statute, which generally requires approval by the disinterested directors or supermajority approval by shareholders for "affiliated transactions" between a corporation and an "interested stockholder." Additionally our organizational documents contain provisions:

· Authorizing the issuance of preferred stock that can be created and issued by the Board of Directors without prior common stock shareholder approval, with rights senior to those of the common stock;

· Restricting persons who may call shareholder meetings;

· Electing directors on a staggered basis; and

. Allowing the Board to fill vacancies and to fix the number of directors.

These provisions of Florida law and tour articles of incorporation and bylaws could negatively affect our share price, prevent attempts by shareholders to remove current management, prohibit or delay mergers or other takeovers or changes of control of the Company and discourage attempts by other companies to acquire us, even if such a transaction would be beneficial to our shareholders.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

Our corporate headquarters are located in Marietta, Georgia, where we lease approximately 80,000 square feet of office, laboratory, tissue processing and warehouse space.  We also lease approximately 21,000 square feet for a facility in Kennesaw, Georgia, which primarily consists of laboratory, tissue processing and warehouse space.

Item 3. Legal Proceedings

Following the publication of the Untitled Letter from the FDA regarding our injectable products in September 2013, four purported class action lawsuits were filed against us and certain of our executive officers. Two of the lawsuits were filed in the U.S. District Court for the Southern District of New York on September 9, 2013, and September 10, 2013, respectively. The other two lawsuits were filed in the U.S. District Court for the Northern District of Georgia on September 13, 2013, and September 19, 2013, respectively.

Each complaint purports to be brought on behalf of shareholders who purchased our common stock during different time periods, beginning on various dates and all ending on September 4, 2013. The complaints generally allege that, during the differing class periods, all of the defendants violated Sections 10(b) of the Securities Exchange Act of 1934, or the Exchange Act, and SEC Rule 10b-5 and the individual defendants violated Section 20(a) of the Exchange Act in making various statements and alleged omissions related tour belief that FDA approval was not required to market our products, including our micronized products. The complaints seek unspecified damages, interest, attorneys’ fees, and other costs. We and our executive officers intend to vigorously defend against these lawsuits. These cases have now all been removed to, and consolidated in, the United States District Court for the Northern District of Georgia. By order dated December 9, 2013, the Court approved the appointment of a lead plaintiff and a lead counsel. A Consolidated Amended Class Action Complaint, containing substantially the same causes of action and claims for relief as the initial complaints, was filed on January 27, 2014. On February 26, 2014, we filed a Motion to Dismiss on various grounds. The plaintiffs' response to our Motion to Dismiss is due March 28, 2014. We currently believe that the outcome of this litigation will not have a material adverse impact on our financial position or results of operations.

Item 4. Mine Safety Disclosures

Not applicable.

Stock Performance Graph

The Securities and Exchange Commission requires us to present a chart comparing the cumulative total stockholder return on our common stock with the cumulative total stockholder return of: (1) a broad equity market index and (2) a published industry or line-of-business index. We selected the Nasdaq Biotechnology Index based on our good faith determination that this index fairly represents the companies that compete in the same industry or line-of-business as we do. The chart below compares our common stock with the Nasdaq Composite Index and the Nasdaq Biotechnology Index and assumes an investment of $100.00 on December 31, 2008, in each of the common stock, the stocks comprising the Nasdaq Composite Index and the stocks comprising the Nasdaq Biotechnology Index.

Unregistered Sales of Equity Securities and Use of Proceeds

In the fourth quarter of 2013, we issued approximately 639,000 unregistered shares of common stock in connection with the exercise of warrants. Of this amount, 450,000 were exercised at an exercise price of $1.00 per share; 106,000 at $.50 per share and 83,000 at $1.50 per share. Included in the total were 400,000 shares issued to our Chairman and CEO upon exercise of warrants with an exercise price of $1.00 per share. These issuances were exempt under § 4(a)(2) of the Securities Act of 1933.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

We did not repurchase any shares of our common stock in 2013.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the consolidated financial statements and the corresponding notes included elsewhere in this Form 10-K. Certain percentages presented in this discussion and analysis are calculated from the underlying whole dollar amounts and therefore may not recalculate from the rounded numbers used for disclosure purposes. Some of the information contained in this discussion and analysis or set forth elsewhere in this report includes forward-looking statements that involve risks and uncertainties.  You should read the “Risk Factors” section of this report for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

The discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles.  The preparation of these financial statements requires making estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenue, and expenses during the reporting periods.  On an ongoing basis, we evaluate such estimates and judgments, including those described in greater detail below.  We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources.  Actual results may differ from these estimates under different assumptions or conditions.

Overview

MiMedx® is an integrated developer, manufacturer and marketer of patent protected regenerative biomaterial products and bioimplants processed from human amniotic membrane. "Innovations in Regenerative Biomaterials" is the framework behind our mission to give physicians products and tissues to help the body heal itself. Our biomaterial platform technologies include AmnioFix® and EpiFix®, our tissue technologies processed from human amniotic membrane that is derived from donated placentas. Through our donor program, mothers delivering full-term Caesarean section births can elect in advance of delivery to donate the placenta in lieu of having it discarded as medical waste. We process the human amniotic membrane utilizing our proprietary Purion® Process, to produce a safe and effective implant. MiMedx® is the leading supplier of amniotic tissue, having supplied over 200,000 allografts to date for application in the Wound Care, Surgical, Sports Medicine, Ophthalmic and Dental sectors of healthcare. These tissue-based products represented approximately 96% of our revenues in 2011 and 99% of our revenues in 2012 and 2013.

Our EpiFix® allografts are configured for external use. We offer EpiFix® in a sheet form as well as a micronized powder form. Currently, EpiFix® and EpiFix® Micronized are being used to treat chronic wounds, including diabetic foot ulcers, venous stasis ulcers, arterial ulcers and pressure ulcers, burns and surgical wounds (such as wounds following plastic surgery).

Our AmnioFix® allografts consist of three configurations, all configured for internal use:

• AmnioFix® is provided in a sheet form.  It is being used currently in spine, general and urology surgeries to reduce inflammation, enhance non-structural soft tissue healing and to minimize scar tissue.

• AmnioFix® Wrap also is supplied in a sheet form and is configured for the same purposes as AmnioFix®, but is optimized for use as a “wrap” for nerves, tendons or ligaments.

• AmnioFix® Injectable is supplied in micronized powder form used for injection into soft tissue areas to treat conditions such as: tendonitis, including plantar fasciitis, lateral epicondylitis, and medial epicondylitis; bursitis; strains and sprains.

We also process allografts for ophthalmic surgery and dental and oral maxilla facial applications, which are sold on an OEM basis.

 Our assets also include licenses to two medical device technology platforms- HydroFix® and CollaFix™.  Although we had commercialized some products based on the HydroFix® technology, due to the relatively small size of the addressable market for those products, we decided to discontinue that product line in the fourth quarter of 2013. We have yet to commercialize any products using our CollaFix™ technology and continue to assess how best to exploit that technology.

Our distribution model is comprised of direct sales, third party sales agents and stocking distributors that market MiMedx-branded products. We also have several OEM relationships targeting the spine market, as well as the ophthalmic and dental

32

markets. Our current focus is in the U.S. market, though a small portion of our revenues (less than 1%) are from sales outside the U.S. to a handful of stocking distributors.

Recent Events

Centers for Medicare and Medicaid Services Releases New Methodology for Reimbursement for Skin Substitutes

In 2013, 56% of our products were purchased for government accounts, which do not depend on reimbursement from third parties.  With the exception of government accounts, most users of our products are doctors, hospitals or ambulatory surgery centers that rely on reimbursement by third-party payers. Accordingly, our revenues and growth substantially depend on adequate levels of third-party reimbursement from these payers.

Our AmnioFix® surgical products generally are bundled as part of a hospital’s bill for a diagnosis-related group(DRG).  There currently is no third party reimbursement for our injectable products. Most skin substitutes, such as our EpiFix® sheet products, on the other hand, historically have been separately reimbursed by third party payers.

By far, the largest third party payer in the United States is the Medicare program, which is a federally funded program that provides healthcare coverage for senior citizens and the disabled. In addition, while other third party payers have their own process and standards for determining whether to cover and reimburse a procedure for our products, private payers often follow the lead of governmental payers in making coverage and reimbursement determinations.

The Medicare program is administered by the Centers for Medicare and Medicaid Services (CMS). CMS has appointed eight Medicare Administrative Contractors (MACs), which are private insurance companies that serve as agents of CMS in the administration of the Medicare program, including the payment of claims and making coverage decisions for the Medicare-assigned jurisdiction for which they are responsible. In 2012, we did not have any confirmed MAC coverage or reimbursement for our EpiFix® sheet products. At the end of 2013, six of the eight MACs provided reimbursement for our EpiFix® sheet allografts. One additional MAC has agreed to cover those products effective March 1, 2014. Also, for 2014, CMS has changed its methodology for reimbursing skin substitutes used in the hospital outpatient and ambulatory surgery center settings in a way that will make the use of allografts such as EpiFix®, which come in many sizes appropriate to the size of the wound being treated, in those settings more cost effective than many competitive products.

FDA Untitled Letter and Subsequent Developments

Initially, we processed our tissue allografts in only one form, which was a sheet form. In 2011, we introduced a micronized form of our sheet allografts.

The FDA has specific regulations governing human cells, tissues and cellular and tissue-based products, or HCT/Ps. An HCT/P is a product containing or consisting of human cells or tissue intended for transplantation into a human patient. If an HCT/P meets the criteria for regulation solely under Section 361 of the Public Health Service Act (so-called “361 HCT/Ps”), no FDA review for safety and effectiveness under a drug, device, or biological product marketing application is required.

We believe that all of our tissue products qualify as 361 HCT/Ps. On August 28, 2013, however, the FDA issued an Untitled Letter alleging that our micronized allografts do not meet the criteria for regulation solely under Section 361 of the Public Health Service Act and that, as a result, we would need a biologics license to lawfully market the micronized products.

After a series of correspondence and conference calls and a meeting with FDA representatives, in December 2013, the FDA clarified the basis for its position regarding the micronized products. Specifically, the FDA explained its belief that “[c]ryo-milling cut, dehydrated amniotic/chorionic membrane results in a micron-sized powder and the loss of the tensile strength and elasticity that are essential characteristics of the original amniotic/chorionic tissue relating to its utility to function as a ‘physical membrane’ (i.e. covering, barrier).” For this reason, the FDA continues to believe that the micronized products are more than minimally manipulated and the products therefore are not eligible for marketing solely under Section 361 of the Public Health Service Act. We responded to the FDA that while we do not agree with the agency’s position, we understand the agency’s interest in further regulating this emerging technology. Accordingly, we have proposed to the FDA that we will pursue the Investigational New Drug (“IND”) and Biologics License Application (“BLA”) process for certain micronized products, and, in parallel, also proposed to enter into negotiations with the FDA on a plan to transition the micronized products to licensed biological products and continue to market the micronized products under specific conditions. We also have informed the FDA that we are ready to commence discussions regarding this transition plan. There is no guarantee that the FDA will agree to a transition plan or allow us to continue to market our micronized products while we pursue one or more BLAs. If they do allow us to continue to market our micronized products, they may impose conditions, such as labeling restrictions and

33

compliance with Current Good Manufacturing Practices (“cGMP”). It is also possible that we will be required to recall our micronized products. Revenues from micronized product make up about 15% of projected 2014 revenues.

Following the publication of the Untitled Letter from the FDA regarding our micronized products, in September 2013, the trading price of our stock dropped sharply and several purported class action lawsuits were filed against us and certain of our executive officers asserting violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to our belief that FDA approval was not required to market its products, including our micronized products. These cases have now all been removed to, and consolidated in, the United States District Court for the Northern District of Georgia. By order dated December 9, 2013, the Court approved the appointment of a lead plaintiff and a lead counsel. A Consolidated Amended Class Action Complaint, containing substantially the same causes of action and claims for relief as the initial complaints, was filed on January 27, 2014. On February 26, 2014, we filed a Motion to Dismiss on various grounds. The plaintiffs' response to our Motion to Dismiss is due March 28, 2014. We currently believe that the outcome of this litigation will not have a material adverse impact on our financial position or results of operations.

Public Offering of Common Stock

In December of 2013, we completed a public offering (the "Offering”) of 5,750,000 shares of our common stock at $6.80 per share. Proceeds from the Offering, net of underwriting expenses were $36,704,000. In addition, we incurred approximately $194,000 in various legal fees for services related to the Offering.

We intend to use the net proceeds from the Offering for general corporate purposes, including, but not limited to, research, development and further commercialization of our products, obtaining regulatory approvals, funding of our clinical trials, capital expenditures, working capital and future acquisitions of complementary businesses, technology or products, although we currently have no agreements or commitments with respect to any such investment or acquisition.

Critical Accounting Policies

We believe that of our significant accounting policies, which are described in Note 2 to our financial statements appearing elsewhere in this report, the following accounting policies involve a greater degree of judgment and complexity.  

Goodwill and Impairment of Long-Lived Assets

Goodwill is the excess of the purchase price over the fair value of net assets of acquired businesses. Goodwill is tested for impairment annually or whenever an event occurs or circumstances change that would indicate that the carrying amount may be impaired. The test for impairment requires us to make several estimates about fair value, most of which are based on projected future cash flows. Our estimates associated with the goodwill impairment test are considered critical due to the amount of goodwill recorded on our consolidated balance sheets and the judgment required in determining fair value, including projected future cash flows. No goodwill impairment has been recognized during 2013, 2012 or 2011.

Other intangible assets include patents, trademarks, and purchased technology. Intangible assets with a definite life are amortized on a straight-line or accelerated basis, as appropriate, with estimated useful lives ranging from ten to fourteen years, and are tested for impairment whenever events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. Indefinite-lived intangible assets are tested for impairment annually or whenever events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. Refer to Note 6 to the consolidated financial statements in “Item 8. Financial Statements and Supplementary Data” in this Annual Report on Form 10-K for additional information. Our impairment reviews are based on an estimated future cash flow approach that requires significant judgment with respect to future revenue and expense growth rates, selection of appropriate discount rate, asset groupings, and other assumptions and estimates. We use estimates that are consistent with our business plans and a market participant view of the assets being evaluated. Actual results may differ from our estimates. In 2012, because our impairment test indicated that the carrying value of the intangible assets related to HydroFix® exceeded its fair value, an impairment loss of approximately $1,798,000 was recognized and the intangible asset carrying amount was adjusted to its new basis. During the fourth quarter of 2013 we chose to discontinue the HydroFix® product line. This action resulted in an impairment charge of approximately $368,000. This item is included in our Statement of Operations for the year ended December 31, 2013.

34

Fair Value Measurements

We record certain financial instruments at fair value, including: cash equivalents and contingent consideration.  We may make an irrevocable election to measure other financial instruments at fair value on an instrument-by-instrument basis; although as of December 31, 2013 we have not chosen to make any such elections.  Fair value financial instruments are recorded in accordance with the fair value measurement framework.

We also measure certain non-financial assets at fair value on a non-recurring basis.  These non-recurring valuations include evaluating assets such as long-lived assets, and non-amortizing intangible assets for impairment; allocating value to assets in an acquired asset group; and applying accounting for business combinations.  We use the fair value measurement framework to value these assets and reports these fair values in the periods in which they are recorded or written down.

The fair value measurement framework includes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair values in their broad levels.  These levels from highest to lowest priority are as follows: 

• Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities;

• Level 2: Quoted prices in active markets for similar assets or liabilities or observable prices that are based on inputs not quoted on active markets, but corroborated by market data; and

• Level 3: Unobservable inputs or valuation techniques that are used when little or no market data is available.

The determination of fair value and the assessment of a measurement’s placement within the hierarchy requires judgment. Level 3 valuations often involve a higher degree of judgment and complexity.  Level 3 valuations may require the use of various cost, market, or income valuation methodologies applied to unobservable management estimates and assumptions.  Management’s assumptions could vary depending on the asset or liability valued and the valuation method used.  Such assumptions could include: estimates of prices, earnings, costs, actions of market participants, market factors, or the weighting of various valuation methods.  We may also engage external advisors to assist us in determining fair value, as appropriate.

Although we believe that the recorded fair value of our financial instruments is appropriate, these fair values may not be indicative of net realizable value or reflective of future fair values.

Share-based Compensation

We follow the provisions of FASB Accounting Standards Codification (“ASC”) 718, “Compensation — Stock Compensation” (ASC 718), previously referred to as Statement of Financial Accounting Standards No. 123R — Share-based Payments which requires the measurement and recognition of compensation expense for all share-based payment awards either modified or granted to employees and directors based upon estimated fair values.  The Black-Scholes-Merton option-pricing model, consistent with the provisions of ASC 718, was used to determine the fair value of each option granted.  Option valuation models require the input of highly subjective assumptions, including the expected stock price volatility.  We use projected volatility rates, which are based upon historical volatility rates, trended into future years.  Because tour stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of our options.

Debt Instruments with Detachable Warrants and Beneficial Conversion Features

According to ASC470-20 "Debt With Conversion and Other Options", proceeds from the sale of convertible debt instruments with stock purchase warrants (detachable call options) shall be allocated to the two elements based upon the relative fair values of the debt instrument without the warrants and of the warrants themselves at the time of issuance.  The Black-Scholes-Merton pricing model, consistent with the provisions of ASC 470, was used to determine the fair value of each warrant granted.  The portion of the proceeds so allocated to the warrants is accounted for as paid-in capital.  The remainder of the proceeds is allocated to the debt instrument portion of the transaction.  Also, the embedded beneficial conversion feature present in the convertible instrument is recognized separately at issuance by allocating a portion of the proceeds equal to the intrinsic value of that feature to additional paid-in capital.

35

Contingent Consideration

The Agreement and Plan of Merger between us and the former owners of Surgical Biologics (the "Merger”) dated January 5, 2011, involved the potential for the payment of future contingent consideration in our common stock.  The contingent consideration was originally recorded at the estimated fair value of the contingent milestone payment on the acquisition date. The initial payment of contingent consideration was equal to 60% of the excess of the amniotic tissue-based adjusted Gross Revenues in calendar year 2011 over the amniotic tissue-based Gross Revenues in calendar year 2010, minus any FDA approval costs.  The adjustments to Gross Revenues were established in the Agreement and Plan of Merger. The payment was made in an aggregate number of shares of our common stock computed per a specified formula in the Agreement and Plan of Merger. At December 31, 2011, the fair value of the contingent consideration tied to 2011 revenue was calculated to be approximately $3,185,000 and resulted in the issuance of approximately 2,632,576 shares of our common stock in April 2012.  In addition we were required to deliver to the former owners of Surgical Biologics an aggregate number of shares of our common stock valued at 30% of the difference between amniotic tissue-based Gross Revenues in calendar year 2012 and amniotic tissue-based Gross Revenues in calendar year 2011, minus any FDA approval costs.  The fair value of the contingent milestone consideration was remeasured at the estimated fair value as of December 31, 2012, with the change in fair value recognized as income or expense within Other Income (Expense) in the consolidated statements of earnings.  At December 31, 2012, the fair value of the contingent consideration tied to 2012 revenue was calculated to be approximately $5,792,000 and the liability was adjusted and recorded as a non-current liability in the consolidated balance sheet. This debt was satisfied by the issuance of approximately 1,175,000 shares of our common stock in the first quarter of 2013.

Recently Adopted Accounting Pronouncements

We consider the applicability and impact of all Accounting Standards Updates ("ASUs"). For the year ended December 31, 2013, and through the date of this report, all ASUs issued, effective and not yet effective, were assessed and determined to be either not applicable or expected to have minimal impact on our financial position or results of operations.

Results of Operations for the year ended December 31, 2013, compared to the year ended December 31, 2012

Revenue

Total revenue increased $32.1 million, or 119%, from approximately $27.1 million in 2012 to $59.2 million in 2013. The increase in revenue as compared to the prior year is due primarily to increased sales of our amniotic membrane tissue products, EpiFix® and AmnioFix®.

Wound Care market revenue increased by approximately $21.7 million, or 190%, to $33.1 million as compared to $11.4 million in the prior year. Growth was driven by increased revenue in both government and commercial accounts. In the first half of 2012, we sold our products through distributors. In the second half of 2012, we made the strategic decision to hire a direct sales force initially focused on government accounts. While the sales personnel maintain a direct relationship with the physician, the product is sold to government accounts through a distributor that handles all contracting matters, including invoicing and collection. This distributor is a service-disabled veteran owned small business. In January 2013, the Medicare Q code for Epifix® became effective and during the year we received positive coverage decisions from six of eight MACs that process medical claims for Medicare on a regional basis. We added direct sales personnel targeting commercial accounts in those territories where there was MAC coverage. The sales executives hired generally have extensive wound care experience and bring with them existing relationships with physicians.

Surgical and Sports Medicine revenue increased approximately $10.2 million, or 79%, to $23.2 million as compared to $13.0 million in the prior year. The growth was driven by increased use of our AmnioFix ® products in both government and commercial accounts in various sports medicine and surgical applications.

The Other markets category, which includes our Ophthalmic and Dental tissue-based products sold on an OEM basis as well as our HydroFix® medical device product sold through distributors, increased approximately $0.2 million, or 9%, as compared to the prior year.

Tissue Processing Costs and Cost of Products Sold

Cost of products sold as a percentage of revenue improved to 15.8% from 19.2% as compared to the prior year. The improvement was due primarily to the increase in direct sales revenue, favorable product mix and higher production rates that absorb a greater percentage of fixed manufacturing costs.

36

Research and Development Expenses

Our research and development expenses (“R&D expenses”) increased approximately $2.0 million, or 68%, to $4.8 million in 2013, compared to approximately $2.9 million in the prior year. The increase is primarily related to increased investments in clinical trials, personnel costs, lab supplies, and testing costs. Our research and development expenses consist primarily of internal personnel costs, clinical trials, fees paid to external consultants, and supplies and instruments used in our laboratories. Additionally, during 2013, we were granted eight U.S. patents for the amnion technology, two US patents and one Chinese patent for the hydrogel technology, two U.S. patents for the collagen technology, and two Australian patents for the collagen technology.  To date, we have received an additional two U.S. patents for amnion technology in 2014.

Selling, General and Administrative Expenses

Selling, General and Administrative expenses for 2013 increased approximately $26.6 million, or 136%, to $46.2 million compared to $19.6 million for 2012. Selling expense increases were driven by costs associated with building our direct sales organization for government and commercial accounts, where headcount grew by 39 during the year, as well as increased commissions due to higher sales volume.

Additional spending increases included spending on support costs related to medical reimbursement, including our reimbursement hotline; our information technology infrastructure to help manage the growth of the business; and increased share-based compensation expense and a provision for anticipated costs associated with the management incentive program.

Selling, General and Administrative expenses consist of personnel costs, professional fees, sales commissions, sales training costs, industry trade show fees and expenses, product promotions and product literature costs, facilities costs and other sales, marketing and administrative costs, depreciation and amortization, and share-based compensation. Share-based compensation for the years ended December 31, 2013 and 2012, was approximately $6.0 million and $2.5 million, respectively, an increase of approximately $3.5 million or 140%. Increased employee stock option grants reflecting management’s philosophy of aligning employee compensation with investor objectives and the increase in the market price of our common stock were the primary reasons for the increase in expense.

We recorded approximately $1.1 million and $1.4 million in amortization expense related to intangible assets in the years ended December 31, 2013 and 2012, respectively. The decrease of approximately $.3 million is attributable to the impairment related to our HydroFix® product line which we elected to discontinue in the fourth quarter of 2013.  We amortize our intangible assets over a period of 10 to 14 years, which we believe represents the remaining useful lives of the patents underlying the licensing rights and intellectual property.  We do not amortize goodwill but we test our goodwill at least annually for impairment and periodically evaluate other intangibles for impairment based on events or changes in circumstances as they occur.

Net Interest Expense

Results of Operations for the year ended December 31, 2012, compared to the year ended December 31, 2011

Revenue

Total revenue increased from approximately $7.8 million in 2011 to $27.1 million in 2012.  The increase in revenue as compared to the prior year was due primarily to increased sales of our amniotic membrane tissue products, EpiFix® and AmnioFix®.  We experienced an approximate increase of $8.5 million, or 189%, in demand for our products in the Surgical and Sports Medicine market which are predominantly sold through independent sales agents and distributors.  This growth over the prior year was driven by the launch of AmnioFix® Injectable as well as additional surgical applications, such as prostatectomy surgery, where the anti-scarring properties of the tissue were deemed to be beneficial.  The growth in the Wound Care market revenue of approximately $10.2 million, or 870%, as compared to the prior year was driven by the addition of a direct sales force starting in the third quarter and continuing into the fourth quarter focusing on Government accounts.  The sales executives hired have extensive experience in the wound care sector and maintain direct relationships with the physicians. Sales to government accounts are sold through a distributor who handles all of the contracting matters including invoicing and collection.  This distributor is also a service disabled veteran owned small business.  The Other markets category which includes our Ophthalmic and Dental tissue-based products which are sold on an OEM basis, as well as our HydroFix® medical device product sold through distributors, increased approximately $.5 million, or 26%, as compared to the prior year.

Tissue Processing Costs and Cost of Products Sold

Cost of products sold as a percentage of revenue improved to 19.2% from 43.3% as compared to the prior year.  The improvement was due primarily to the increase in direct sales revenue, improved product mix and higher production rates that absorb a greater percentage of fixed manufacturing costs.  During the year we increased our clean room capacity from one line to three lines, added 32 tissue processors to fully staff the new production lines and tripled the number of tissue recovery technicians.

Research and Development Expenses

Our R&D expenses decreased approximately $.09 million, or 3.1%, to $2.9 million during the year ended December 31, 2012, compared to approximately $3.0 million in the prior year.  The decrease is primarily related to the closure of our Tampa research facility in mid-2011, along with decreased spending on animal studies for our CollaFix™ and HydroFix® products.

Selling, General and Administrative Expenses

38

Selling, General and Administrative expenses for the year ended December 31, 2012, increased approximately $9.8 million, or 100%, to $19.6 million compared to $9.8 million for the year ended December 31, 2011. Selling expense increases were driven by costs associated with building our direct sales organization for government accounts and commercial accounts for wound care, building a customer service and sales training organization, as well as increased commissions due to higher sales volume paid to both company personnel as well as third party representatives and distributors.  Also contributing to the increase was higher spending on support costs related to medical reimbursement including our reimbursement hotline, our information technology infrastructure to help manage the growth of the business, increased marketing costs including trade shows, increased share-based compensation expense and a provision for anticipated costs associated with our management incentive program. Share-based compensation for the years ended December 31, 2012 and 2011 was approximately $2.5 million and $1.6 million, respectively, an increase of approximately $.9 million or 56%. Increased employee stock option grants reflecting management’s philosophy of aligning employee compensation with investor objectives and the increase in the market price of our common stock were the primary reasons for the increase in expense.

We recorded approximately $1.4 million and $1.3 million in amortization expense related to intangible assets in the years ended December 31, 2012 and 2011, respectively.  The increase of approximately $.1 million was the result of additional amortization recognized in the current year related to our development costs of our AmnioFix® Injectable product that we began selling in early 2012.  We amortize our intangible assets over a period of 10 to 14 years, which we believe represents the remaining useful lives of the patents underlying the licensing rights and intellectual property.  We do not amortize goodwill but we test our goodwill at least annually for impairment and periodically evaluate other intangibles for impairment based on events or changes in circumstances as they occur.

Net Interest Expense

We recorded financing and net interest expense of approximately $2.3 million during the year ended December 31, 2012, compared with approximately $.4 million of financing and net interest expense during the year ended December 31, 2011.  The increase of approximately $1.9 million was primarily due to interest related to our Convertible Senior Secured Promissory Notes, which were issued during the last quarter of 2011.  The following table summarizes the interest charges for the years ended December 31, 2012 and 2011.

In January and February of 2013 all holders of Senior Secured Promissory notes, including our Chairman and CEO, elected to convert their notes into common stock, resulting in the issuance of approximately 5,272,000 shares of common stock which represents the face value of their respective notes plus accrued but unpaid interest. Our Chairman and CEO received 532,260 shares of common stock upon conversion of his note.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements.

Liquidity and Capital Resources

Our net working capital at December 31, 2013, increased $42.7 million to $55.8 million from $13.1 million at December 31, 2012. The current ratio increased to 6.8 as of December 31, 2013, as compared to 3.6 at December 31, 2012. The increase in working capital was primarily due to an increase in cash and cash equivalents on hand of $37.3 million due primarily to the cash raised in the Public Offering of common stock that closed in December 2013.

As of December 31, 2013, we had approximately $44.1 million of cash and cash equivalents. We reported total current assets of approximately $65.4 million and current liabilities of approximately $9.6 million.  We believe that our anticipated cash from operating activities and existing cash and cash equivalents will enable us to meet our operational liquidity needs and fund our planned investing activities for the next year.

Discussion of cash flows

Net cash used in operations during the year ended December 31, 2013, decreased approximately $3.0 million to $.3 million, compared to $3.3 million used in operating activities for the year ended December 31, 2012, and was primarily attributable to the decrease in the Net Loss.

Net cash used in investing activities during the year ended December 31, 2013, increased approximately $2.4 million to $3.0 million compared to $0.6 million used in investing activities for the year ended December 31, 2013. The increase was due to purchases of plant and equipment related to our relocation to a new facility with expanded production capacity and capitalization of patent application costs.

Net cash flows from financing activities during the year ended December 31, 2013, increased approximately $34 million to $40.6 million compared to $6.6 million during the year ended December 31, 2012. Cash flows from financing activities during the past 12 months include $36.7 million, net of underwriting expenses, raised in December, 2013 from the follow on offering of approximately 5.8 million shares of common stock. Also included is $2.1 million received from the exercise of warrants compared to approximately $6.0 million in the prior year and approximately $2.0 million received from the exercise of stock options compared to $1.1 million in the prior year.

Due to the material amount of non-cash related items included in our results of operations, we have developed an Adjusted EBITDA metric that provides management with a clearer view of operational use of cash (see the table below). Our Adjusted EBITDA for the year ended December 31, 2013, was approximately $5.5 million which is an improvement of approximately $3.1 million as compared to 2012 and an improvement of $11.8 million compared to 2011. These year-over-year improvements were the result of a lower net loss in 2013 as compared to 2012 and a lower net loss in 2012 as compared to 2011.

Adjusted EBITDA is a non-GAAP measure. Non-GAAP financial measures are commonly used in the industry and are presented because management believes they provide relevant and useful information to investors. However, there are limitations to using these non-GAAP financial measures. Adjusted EBITDA is not indicative of cash provided or used by

40

operating activities and may differ from comparable information provided by other companies. Adjusted EBITDA should not be considered in isolation, as an alternative to, or more meaningful than measures of financial performance determined in accordance with U.S. GAAP. The following table presents a reconciliation of Adjusted EBITDA to the most closely related financial measure reported under GAAP for the years ended December 31, 2013, 2012 and 2011.

Inflation

We do not believe that the rate of inflation has had a material effect on our operating results.  However, inflation could adversely affect our future operating results.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Based on our lack of market risk sensitive instruments outstanding at December 31, 2013, we have determined that there was no material market risk exposure to our consolidated financial position, results of operations or cash flows as of such date.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and

Stockholders of MiMedx Group, Inc.

We have audited the accompanying consolidated balance sheets of MiMedx Group, Inc. and subsidiaries as of December 31, 2013 and 2012, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the years ended in the three-year period ended December 31, 2013. We have also audited the accompanying consolidated financial statement schedule for each of the three years in the period ended December 31, 2013 listed in the index at Item 15.  These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States of America). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of MiMedx Group, Inc. and subsidiaries as of December 31, 2013 and 2012, and the consolidated results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related consolidated financial statement schedule for each of the three years in the period ended December 31, 2013, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States of America), MiMedx Group, Inc.’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 4, 2014 expressed an unqualified opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and

Stockholders of MiMedx Group, Inc.

We have audited MiMedx Group, Inc.’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). MiMedx Group, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States of America). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 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.

In our opinion, MiMedx Group, Inc maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States of America), the consolidated balance sheets of MiMedx Group, Inc. and subsidiaries as of December 31, 2013 and 2012, and the related consolidated statements of operations, stockholders’ equity, and cash flows for the years ended December 31, 2013, 2012 and 2011, and our report dated March 4, 2014 expressed an unqualified opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE FISCAL YEARS ENDED DECEMBER 31, 2013 AND 2012

1. Nature of Business

MiMedx Group, Inc. (“MiMedx,” "the Company,” “we,” or “us”) operates in one business segment, Regenerative Biomaterials, which includes the design, manufacture, and marketing of products and tissue processing services for the Wound Care, Surgical, Sports Medicine, Ophthalmic and Dental market categories.  Our biomaterial platform technologies include tissue technologies, AmnioFix® and EpiFix®, and device technology CollaFix^™ .

The Company is focused primarily on the United States but will pursue other individual markets based upon the specific opportunity.  The adoption of the technologies may vary depending on each country’s regulations, but the opportunities to help individuals in the different disease states remain similar and large.

2 Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported consolidated statements of operations during the reporting period.  Actual results could differ from those estimates.

Principles of Consolidation

The accompanying financial statements include the accounts of MiMedx Group, Inc. and its wholly-owned subsidiaries MiMedx, Inc., SpineMedica, LLC, and MiMedx Tissue Services, LLC, formerly known as Surgical Biologics, LLC. All significant inter-company balances and transactions have been eliminated.

Reclassifications

Certain amounts in the prior year financial statements have been reclassified to conform to the current year financial statement presentation.

Segment Reporting

ASC 280, “Segment Reporting” requires use of the “management approach” model for segment reporting.  The management approach model is based on the way a company’s management organizes segments within the company for making operating decisions and assessing performance. The Company determined it has one operating segment.  Disaggregation of the Company’s operating results is impracticable, because the Company’s research and development activities and its assets overlap, and management reviews its business as a single operating segment.  Thus, discrete financial information is not available for more than one operating segment.

Market Concentrations and Credit Risk

The Company places its cash and cash equivalents on deposit with financial institutions in the United States.  In July 2010, the Federal Deposit Insurance Corporation (“FDIC”) increased coverage to $250,000 for substantially all depository accounts. As of December 31, 2013, the Company had cash and cash equivalents of approximately $43,600,000 in excess of the insured amounts.

The Company’s principal market concentration of risk is related to its limited distribution channels.  The Company's revenues include the distribution efforts of several independent companies as well as the Company's internal sales force. Significant revenues are derived from its relationships with two of its distributors, AvKARE, Inc. which sells our products to the Federal government and another distributor that sells our products in certain defined Territories. For the years ended December 31, 2013, 2012 and 2011, AvKARE revenue was 56%, 40%, and 0% of total revenue, respectively. Related receivables for the same time periods were 55%, 53%, and 0%, of total accounts receivable, respectively. For the years ended December 31, 2013, 2012 and 2011, the other distributor's revenue was 10%, 21%, and 19% of total revenue, respectively. Related receivables for the same time periods were 12%, 25%, and 33% of total accounts receivable, respectively.

Cash and Cash Equivalents

49

Cash and cash equivalents include all highly liquid investments with an original maturity of three months or less.

Accounts Receivable

Accounts receivable represent amounts due from customers for which revenue has been recognized.  Generally, the Company does not require collateral or any other security to support its receivables.

Inventories

Inventories are valued at the lower of cost or market, using the first–in, first-out (FIFO) method.  Inventory is tracked through Raw Material, WIP, and Finished Good stages as the product progresses through various production steps and stocking locations. Labor and overhead costs are absorbed through the various production processes upon work order closes. Historical yields and normal capacities are utilized in the calculation of production overhead rates.  Reserves for inventory obsolescence are utilized to account for slow-moving inventory as well as inventory no longer needed due to diminished market demand.

Goodwill and Purchased Intangible Assets

Goodwill and purchased intangible assets with indefinite useful lives are not amortized but are tested for impairment at least annually.  The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually at the beginning of its fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable.  For goodwill, the Company performs a two-step impairment test.  In the first step, the Company compares the fair value of the Company to its carrying value.  The Company determines the fair value utilizing the market approach.  Under the market approach, the Company uses its market capitalization which is calculated by taking the Company’s share price times the number of outstanding shares.  If the fair value of the Company exceeds the carrying value of the net assets, goodwill is not impaired, and no further testing is required.  If the fair value of the Company is less than the carrying value, the Company must perform the second step of the impairment test to measure the amount of impairment loss, if any. In the second step, the Company’s value is allocated to all of the assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the Company was being acquired in a business combination.  If the implied fair value of the reporting unit's goodwill is less than the carrying value, the difference is recorded as an impairment loss.

Impairment of Intangible Assets with Finite Lives

The Company reviews purchased intangible assets with finite lives for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable using a two-step impairment test. In step one, we determine the sum of the undiscounted future cash flows of the assets based on management's estimates and compare it to the carrying value of the assets. If the carrying amount is greater than the sum of the undiscounted cash flows, then the asset is impaired and step two is required. In step two, the impairment loss is calculated as the difference between the fair value of the assets and the carrying value of the assets.

Our impairment reviews are based on an estimated future cash flow approach that requires significant judgment with respect to future revenue and expense growth rates, selection of appropriate discount rate, asset groupings, and other assumptions and estimates. We use estimates that are consistent with our business plans and a market participant view of the assets being evaluated. Actual results may differ from our estimates.

During the fourth quarter we chose to discontinue the HydroFix^® product line. This action resulted in an impairment charge of approximately $368,000 related to the Licenses for SaluMedica LLC, Spine Repair and Polyvinyl Alcohol Cryogel. This item is included in our Statement of Operations as of for the year ended December 31, 2013. An impairment charge of approximately $1,800,000 had previously been booked in 2012.

Property and Equipment

Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives, principally five to seven years.  Leasehold improvements are depreciated on a straight-line basis over the lesser of the estimated useful lives or the life of the lease. The Company is party to various lease arrangements for its facility space and equipment. These arrangements include interest, scheduled rent increases and rent holidays which are included in the determination of minimum lease payments when assessing lease classification, and are included in rent expense on a straight line basis over the lease term. See Notes 5 and 15 for further information regarding capital leases, operating leases and rent expense.

50

Patent Costs

The Company incurs certain legal and related costs in connection with patent applications for tissue based products and processes. The Company capitalizes such costs to be amortized over the expected life of the patent to the extent that an economic benefit is anticipated from the resulting patent or alternative future use is available to the Company. The Company capitalized approximately $690,000 of patent costs during 2013. There were no patent costs capitalized in 2012 or 2011.

Impairment of Long-lived Assets

The Company evaluates the recoverability of its long-lived assets (property and equipment) whenever adverse events or changes in business climate indicate that the expected undiscounted future cash flows from the related assets may be less than previously anticipated.  If the net book value of the related assets exceeds the expected undiscounted future cash flows of the assets, the carrying amount would be reduced to the present value of their expected future cash flows and an impairment loss would be recognized. During the fourth quarter of 2013, we chose to discontinue the HydroFix® product line. This action resulted in a disposal loss of approximately $30,000. This item is included in our Consolidated Statements of Operations for the year ended December 31, 2013, as Selling, General and Administrative expenses.

Grant Income

The Company received a Regional Economic Business Assistance ("REBA") grant in the amount of $250,000 from the State of Georgia to help the Company defray certain expenses and capital expenditures related to the Company's expansion of manufacturing activities in the State.  In order to retain the grant monies the Company was required to add a certain number of full time positions and spend a certain amount on capital and operations expenditures by December 31, 2014. As of December 31, 2013, the Company had satisfied the grant requirements. Accordingly, the Company has recorded the $250,000 as a reduction of Selling, General and Administrative expenses in the accompanying Consolidated Statements of Operations. Previously, this amount was recorded as Deferred Grant Income and was included in Other Liabilities per ASC 450-30 Gain Contingencies.

Debt Instruments with Detachable Warrants and Beneficial Conversion Features

According to ASC470-20 "Debt With Conversion and Other Options", proceeds from the sale of convertible debt instruments with stock purchase warrants (detachable call options) shall be allocated to the two elements based upon the relative fair values of the debt instrument without the warrants and of the warrants themselves at the time of issuance.  The portion of the proceeds so allocated to the warrants shall be accounted for as paid-in capital.  The remainder of the proceeds shall be allocated to the debt instrument portion of the transaction.  Also, the embedded beneficial conversion feature present in the convertible instrument shall be recognized separately at issuance by allocating a portion of the proceeds equal to the intrinsic value of that feature to additional paid-in capital.

Revenue Recognition

The Company sells its products primarily through a combination of a direct sales force, independent stocking distributors and third party representatives in the U.S. and independent distributors in international markets.  The Company recognizes revenue when title to the goods and risk of loss transfers to customers, provided there are no material remaining performance obligations required of the Company or any matters of customer acceptance.  In cases where the Company utilizes distributors or ships products directly to the end user, it recognizes revenue according to the shipping terms of the agreement provided all revenue recognition criteria have been met.  A portion of the Company’s revenue is generated from inventory maintained at hospitals or with field representatives.  For these products, revenue is recognized at the time the product has been used or implanted.  The Company records estimated sales returns, discounts and allowances as a reduction of net sales in the same period revenue is recognized.

Research and Development Costs

Research and development costs consist of direct and indirect costs associated with the development of the Company’s technologies.  These costs are expensed as incurred.

Income Taxes

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of

51

a change in tax rates is recognized in the period that included the enactment date.  Valuation allowances are recorded for deferred tax assets when the recoverability of such assets is not deemed more likely than not.

Uncertain Tax Positions

Tax positions are evaluated in a two-step process.  The Company first determines whether it is more likely than not that a tax position will be sustained upon examination.  If a tax position meets the more-likely-than-not recognition threshold it is then measured to determine the amount of benefit to recognize in the financial statements.  The tax position is measured as the largest amount of benefit that is more than 50% likely of being realized upon ultimate settlement.  The Company classifies gross interest and penalties and unrecognized tax benefits that are not expected to result in payment or receipt of cash within one year as non-current liabilities in the Consolidated Balance Sheets.

Share-based Compensation

The Company follows the provisions of ASC topic 718 “Compensation — Stock compensation”, which requires the use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares of stock or equity instruments (options and warrants).  All awards are amortized on a straight-line basis over their vesting terms.

Fair Value of Financial Instruments

The respective carrying value of certain on-balance-sheet financial instruments approximated their fair values due to the short-term nature of these instruments. These financial instruments include cash, accounts receivable, accounts payable and accrued expenses. The fair value of the Company’s capital leases approximates its carrying value based upon current rates available to the Company.

Fair Value Measurements

The Company records certain financial instruments at fair value, including: cash equivalents and contingent consideration.  The Company may make an irrevocable election to measure other financial instruments at fair value on an instrument-by-instrument basis; although as of December 31, 2013, the Company has not chosen to make any such elections.  Fair value financial instruments are recorded in accordance with the fair value measurement framework.

The Company also measures certain non-financial assets at fair value on a non-recurring basis.  These non-recurring valuations include evaluating assets such as long-lived assets; and non-amortizing intangible assets for impairment; allocating value to assets in an acquired asset group; and applying accounting for business combinations.  The Company uses the fair value measurement framework to value these assets and reports these fair values in the periods in which they are recorded or written down.

The fair value measurement framework includes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair values in their broad levels.  These levels from highest to lowest priority are as follows:

• Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities;

• Level 2: Quoted prices in active markets for similar assets or liabilities or observable prices that are based on inputs not quoted on active markets, but corroborated by market data; and

• Level 3: Unobservable inputs or valuation techniques that are used when little or no market data is available.

The determination of fair value and the assessment of a measurement’s placement within the hierarchy require judgment. Level 3 valuations often involve a higher degree of judgment and complexity.  Level 3 valuations may require the use of various cost, market, or income valuation methodologies applied to unobservable management estimates and assumptions.  Management’s assumptions could vary depending on the asset or liability valued and the valuation method used.  Such assumptions could include: estimates of prices, earnings, costs, actions of market participants, market factors, or the weighting of various valuation methods.  The Company may also engage external advisors to assist it in determining fair value, as appropriate.

Although the Company believes that the recorded fair value of its financial instruments is appropriate, these fair values may not be indicative of net realizable value or reflective of future fair values.

52

Recently Issued Accounting Pronouncements

The Company considers the applicability and impact of all Accounting Standards Updates "ASUs". For the year ended December 31, 2013, and through the date of this report, all ASUs issued, effective and not yet effective, were assessed and determined to be either not applicable or are expected to have minimal impact on our financial position or results of operations.

3. Liquidity and Management's Plans

As of December 31, 2013, the Company had approximately $44,100,000 of cash and cash equivalents.  The Company reported total current assets of approximately $65,400,000 and current liabilities of approximately $9,600,000.  The Company believes that its anticipated cash from operating and financing activities and existing cash and cash equivalents will enable the Company to meet its operational liquidity needs and fund its planned investing activities for the next year.

(a) On January 29, 2007, the Company acquired a license from Shriners Hospitals for Children and University of South Florida Research Foundation, Inc. in the amount of $996,000.  Within 30 days after the receipt by the Company of approval by the FDA allowing the sale of the first licensed product, the Company is required to pay an additional $200,000 to the licensor.  Due to its contingent nature, this amount is not recorded as a liability. The Company will also be required to pay a royalty of 3% on all commercial sales revenue from the licensed products. The Company is also obligated to pay a $50,000 minimum annual royalty payment over the life of the license. As of December 31, 2013, this license had a remaining net book value of approximately $309,000.

(b) On September 1, 2005, we acquired a license from SaluMedica, LLC (SaluMedica) in the original amount of $2,399,000 for the use of certain developed technologies related to spine repair. This license was acquired through the acquisition of SpineMedica Corp. In 2012, we booked an impairment charge related to this asset of $851,676. In the fourth quarter of 2013, the Company made a decision to discontinue marketing the HydroFix^® product line and fully impaired the asset. There was no charge to Operations as the asset was fully amortized.

(c) On March 31, 2008, the Company entered into a license agreement for the use of certain developed technologies related to surgical sheets made of polyvinyl alcohol cryogel in the original amount of $2,667,000. In 2012, we booked an impairment charge related to this asset of $946,819. In the fourth quarter of 2013, the Company made a decision to discontinue marketing the HydroFix^® product line and fully impaired the asset. This resulted in an impairment charge of $368,102 which is included in the Company's Statement of Operations.

(d) On January 5, 2011, the Company acquired Surgical Biologics, LLC.  As a result, the Company recorded intangible assets for Customer & Supplier Relationships of $3,761,000, Patents & Know-How of $7,690,000, Licenses of $13,000, Trade Names & Trademarks of $1,008,000 and In-Process Research & Development of $25,000. During 2013 an additional $108,910 of costs associated with patents granted during the year were capitalized and included in Patents & Know- How subject to amortization.

54

(e) Capitalized external legal and other registration costs in connection with internally developed tissue-based patents that are pending. Once issued, the costs associated with a given patent will be included in Patents & Know-How under intangible assets subject to amortization.

Amortization expense for the years ended December 31, 2013, 2012, and 2011, was approximately $1,054,000, $1,380,000, and $1,336,000, respectively.

Expected future amortization of intangible assets as of December 31, 2013, is as follows:

	Estimated
	Amortization
Year ending December 31,	Expense
2014	$	923,935
2015	923,935
2016	923,935
2017	834,302
2018	824,335
Thereafter	5,740,131
	$	10,170,573

7. Long-Term Debt

The following table summarizes our long-term debt:

	December 31, 2013		December 31, 2012
$5,000,000 Convertible Senior Secured Promissory Notes including interest at 5% per annum payable quarterly through December 31, 2013, and an additional one time 5% interest charge payable on January 15, 2013, if not repaid by December 31, 2012, collateralized by a first priority lien shared equally with holder of the Convertible Line of Credit with Related Party in all of the patents and intellectual property owned by the Company subordinated to the Convertible Debt related to acquisition for Surgical Biologics intellectual property until repaid. (a)	$	—	$	5,313,645
Total debt	—		5,313,645
Less unamortized debt discount	—		(1,301,203		)
Less current portion	—		—
Long-term portion	$	—	$	4,012,442

(a) Investors received First Contingent Warrants (25% of amount invested) and Second Contingent Warrants (25% of amount invested) at an exercise price of $.01 per share. On December 31, 2011, a total of 1,250,000 First Contingent Warrants were vested. In July 2012, a total of 1,250,000 Second Contingent Warrants were voided due to the Company's share price trading at or above $1.75 for ten consecutive trading days. The additional interest resulting from the beneficial conversion feature, inclusive of the First Contingent Warrants, totaled $2,278,052, which was recorded as a debt discount and was amortized to interest expense using the effective interest rate over the life of the note.

Senior Secured Promissory Notes

From December 27 to December 31, 2011, the Company sold 5% Convertible Senior Secured Promissory Notes (the “Notes”) to individual accredited investors for aggregate proceeds of $5,000,000.  The aggregate proceeds included $500,000 of Notes sold to the Company’s Chairman of the Board and CEO.  In total, the principal of the Notes were convertible into up to 5,000,000 shares of common stock of the Company (“Common Stock”) plus accrued but unpaid interest at $1.00 per share at any time upon the election of the holder of the note.

55

In conjunction with the sale of the Notes, the Company incurred a placement fee of $32,800 and issued 42,400 common stock warrants to the placement agents at an exercise price of $1.09 per share.  The warrants expire in 5 years.  The fair value of the warrants was determined to be approximately $15,000 using the Black-Scholes-Merton valuation technique.  The total direct costs of approximately $47,800 were recorded as deferred financing costs and were amortized over the term of the Notes using the effective interest method.  Further, the placement agent warrants are classified in stockholders’ equity because they achieved all of the requisite conditions for equity classification in accordance with GAAP.

During the months of January and February 2013, all holders of the Notes converted their interest in this obligation to shares of MiMedx common stock.  The total amount of debt plus accrued interest that was exchanged was approximately $5,272,000.  In conjunction with this exchange, approximately 5,272,000 shares of the Company’s common stock were issued in full satisfaction of this obligation.  Included in this total are 532,260 shares representing the Chief Executive Officer’s conversion of his Note.  This also resulted in the acceleration of amortization of debt discount and total interest expense of approximately $1,328,000 during the year ended December 31, 2013.

Line of Credit

On May 17, 2013, the Company and Bank of America, N.A. (the “Lender”) entered into a Loan Agreement (the “Loan Agreement”).  The Loan Agreement provides the Company with a secured revolving line of credit (the “Revolving Line of Credit”) of up to $3,000,000, and includes a sub-limit of up to $1,000,000 for the issuance of letters of credit.  The Revolving Line of Credit is secured by the Company's accounts receivable and inventory.  The Company intends to utilize the Revolving Line of Credit for general corporate purposes. As of the date of this filing, the Company has not made any draws under the Revolving Line of Credit.

Accrued interest with respect to principal amounts outstanding under the Loan Agreement is payable in arrears on a monthly basis calculated at the rate of LIBOR plus two percent (2%). The principal amount outstanding under the Loan Agreement and any accrued and unpaid interest are due no later than May 1, 2014, and the Revolving Line of Credit is subject to certain prepayment penalties upon early termination of the Revolving Line of Credit.   The Loan Agreement is subject to renewal by the lender at the end of the term.

The Loan Agreement contains covenants that limit under certain circumstances the ability of the Company to, among other things, merge with or acquire other entities, incur new liens, incur additional indebtedness, sell assets outside of the ordinary course of business, make loans, advances or other extensions of credit or engage in any business activities substantially different from the Company's current business without the Lender's consent. The Loan Agreement also requires the Company to maintain certain financial covenants, including a minimum funded debt to adjusted EBITDA ratio and a minimum fixed charge coverage ratio. The Company is in compliance with these covenants.

8. Net Income (loss) Per Share

Basic net income (loss) per common share is computed using the weighted-average number of common shares outstanding during the period.  Diluted net loss per common share is computed using the weighted-average number of common and dilutive common equivalent shares from stock options, warrants and convertible debt using the treasury stock method.  For all periods presented, diluted net loss per share is the same as basic net loss per share, as the inclusion of equivalent shares from outstanding common stock options, warrants and convertible debt would be anti-dilutive.

The following table sets forth the computation of basic and diluted net loss per share:

	Year Ended December 31,
	2013			2012			2011
Net income (loss)	$	(4,111,853	)	$	(7,662,376	)	$	(10,193,986	)
Denominator for basic earnings per share - weighted average shares	96,285,504			81,646,295			72,450,337
Effect of dilutive securities: Stock options and warrants outstanding and convertible debt (a)	—			—			—
Denominator for diluted earnings per share - weighted average shares adjusted for dilutive securities	96,285,504			81,646,295			72,450,337
Income (loss) per common share - basic and diluted	$	(0.04	)	$	(0.09	)	$	(0.14	)

56

(a) Securities outstanding that were excluded from the computation, prior to the use of the treasury stock method, because they would have been anti-dilutive are as follows:

	Year Ended December 31,
	2013	2012	2011
Outstanding Stock Options	15,375,960	13,614,135	10,333,583
Outstanding Warrants	1,284,816	3,129,168	9,388,817
Convertible Debt, promissory notes	—	5,313,645	5,007,732

Convertible Debt, Acquisition	—	—	1,299,315
	16,660,776	22,056,948	27,372,173

9. Common Stock Placements

Public Offering of Common Stock

In December of 2013, the Company completed a public offering the 'Offering” of 5,750,000 shares of its common stock at $6.80 per share. Proceeds from The Offering net of underwriting expenses of the Offering were $36,704,000. In addition, we incurred approximately $194,000 in various legal fees for services related to The Offering.

We intend to use the net proceeds from The Offering for general corporate purposes, including, but not limited to, research, development and further commercialization of our products, obtaining regulatory approvals, funding of our clinical trials, capital expenditures, working capital and future acquisitions of complementary businesses, technology or products, although we currently have no agreements or commitments with respect to any such investment or acquisition.

Each of our executive officers and directors, has agreed that, subject to certain exceptions, during the period ending 90 days after December 9, 2013, which we refer to as the restricted period, without the prior consent of Canaccord Genuity Inc., (the lead underwriter for The Offering) not to directly or indirectly offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise dispose of any shares of common stock or any securities that may be converted into or exchanged for any shares of our common stock, enter into any swap or other arrangement that transfers to another person, in whole or in part, any of the economic consequences of ownership of our common stock. The foregoing restrictions do not apply with respect to an aggregate of 150,000 shares of common stock held by certain entities in which our Chairman and Chief Executive Officer possesses sole voting and investment control.

10. Equity

Stock Incentive Plans

The Company has three share-based compensation plans: the MiMedx Group, Inc. Assumed 2006 Stock Incentive Plan (the “2006 Plan”), the MiMedx Inc. 2007 Assumed Stock Plan (the “Assumed 2007 Plan”) and the MiMedx Group Inc. Amended and Restated Assumed 2005 Stock Plan (the “Assumed 2005 Plan”) which provide for the granting of qualified incentive and non-qualified stock options, stock appreciation awards and restricted stock awards to employees, directors, consultants and advisors. The awards are subject to a vesting schedule as set forth in each individual agreement. The Company intends to use only the 2006 Plan to make future grants. The number of assumed options under the Assumed 2005 Plan and Assumed 2007 Plan outstanding at December 31, 2013, totaled 375,000.  On March 6, 2013, the Board of Directors approved 6,000,000 additional shares to be made available under the 2006 Plan, bringing the maximum number of shares of common stock which can be issued under the 2006 Plan to 22,500,000 at December 31, 2013. The shareholders approved the increase on May 9, 2013.

A summary of the status of the Company’s unvested stock options as of December 31 is presented below:

	2013
Unvested Stock Options	Number of Shares		Weighted- Average Grant Date Fair Value
Unvested at January 1, 2013	8,377,538		$	0.96
Granted	4,021,000		$	3.08
Cancelled/expired	(265,002	)	$	2.14
Vested	(3,565,308	)	$	0.94
Unvested at December 31, 2013	8,568,228		$	1.94

Total unrecognized compensation expense at December 31, 2013, was approximately $12,052,935 and will be charged to expense through February 2016.

The fair value of the options granted was estimated on the date of grant using the Black-Scholes-Merton option-pricing model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate.  Expected volatilities are based on historical volatility of peer companies and other factors estimated over the expected term of the options.  The term of employee options granted is derived using the “simplified method” which computes expected term as the average of the sum of the vesting term plus the contract term.  The simplified method was used due to the Company’s lack of sufficient historical data to provide a reasonable basis upon which to estimate the expected term due to the limited period of time its equity shares have been publicly traded.  The term for non-employee options is generally based upon the contractual term of the option.  The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term or contractual term as described.

The assumptions used in calculating the fair value of options using the Black-Scholes-Merton option-pricing model are set forth in the following table:

	Year ended December 31,
	2013	2012	2011
Expected volatility	61.41 - 64.77%	45.7 - 64.3%	57.3-58.1%
Expected life (in years)	6	6	6
Expected dividend yield	—	—	—
Risk-free interest rate	0.85 - 1.88%	0.62 - 1.77%	0.86 - 2.24%

The weighted-average grant date fair value for options granted during the years ended December 31, 2013, 2012 and 2011 were approximately $3.08, $1.07, and $0.63, respectively.

Restricted Stock Awards

Following is summary information for restricted stock awards for the years ended 2013 and 2012. There were no restricted stock awards in 2011 and prior years. Shares vest over a one to three year period. As of December 31, 2013, there was approximately $2,471,000 of total unrecognized stock-based compensation related to time-based, nonvested restricted stock.  That expense is expected to be recognized on a straight-line basis over a weighted-average period of 2.5 years.

Warrants may be exercised in whole or in part by:

• notice given by the holder accompanied by payment of an amount equal to the warrant exercise price multiplied by the number of warrant shares being purchased; or

• if permitted by the applicable warrant election by the holder to exchange the warrant (or portion thereof) for that number of shares equal to the product of (a) the number of shares issuable upon exercise of the warrant (or portion) and (b) a fraction, (x) the numerator of which is the market price of the shares at the time of exercise minus the warrant exercise price per share at the time of exercise and (y) the denominator of which is the market price per share at the time of exercise.

61

These warrants are not mandatorily redeemable, and do not obligate the Company to repurchase its equity shares by transferring assets or issuing a variable number of shares.

The warrants require that the Company deliver shares as part of a physical settlement or, if permitted by the applicable warrant a net-share settlement, at the option of the holder, and do not provide for a net-cash settlement.

All of our warrants are classified as equity as of December 31, 2013, December 31, 2012, and December 31, 2011.

11. Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Significant components of the Company’s deferred tax assets and liabilities are as follows:

	December 31,
	2013			2012
Deferred tax assets and liabilities:
Accrued liabilities	$	1,404,000		$	(125,000	)
Beneficial conversion feature on convertible financial instruments	—			(449,000		)
Intangible assets	1,021,000			1,117,000
Property and equipment	(507,000		)	89,000
R&D Credit Carryforward	1,369,000			1,407,356
Stock Compensation	2,151,000			213,000
Adjust accrued earn-out liability	—			567,947
Charitable Contributions	1,000			3,000
Patent fees	142,000			6,000
Net operating loss	14,663,000			15,539,000
Net deferred tax assets	$	20,244,000		$	18,368,303
Valuation allowance	(20,244,000		)	(18,368,303		)
	$	—		$	—

The reconciliation of the Federal statutory income tax rate of 34% to the effective rate is as follows:

	December 31,
	2013		2012
Federal statutory rate	34.00	%	34.00	%
State taxes, net of federal benefit	(2.48	)%	3.40	%
Permanent items & other	12.73	%	0.65	%
Valuation allowance	(46.73	)%	(38.05	)%
	(2.48	)%	—	%

Income taxes are based on estimates of the annual effective tax rate and evaluations of possible future events and transactions and may be subject to subsequent refinement or revision.

Certain items of income and expense are not reported in tax returns and financial statements in the same year. The tax effect of such temporary differences is reported as deferred income taxes. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefit that, based on available evidence, is not expected to be realized. The Company establishes a valuation allowance for deferred tax assets for which realization is not likely. At December 31, 2013, the Company had a valuation allowance of $20,244,000 recorded against the benefit of certain deferred tax assets. In assessing the recoverability of our deferred tax assets, we analyzed all evidence, both positive and negative. We considered, among other

62

things, our deferred tax liabilities, our historical earnings and losses, projections of future income, and tax-planning strategies available to us in the relevant jurisdiction.

At December 31, 2013, we have income tax net operating loss ("NOL") carry forwards for federal and state purposes of $36,861,000 and $30,036,000, respectively. The Company has recorded a deferred tax asset for both federal and state income taxes of $12,533,000 and $2,130,000, respectively. If not utilized, the federal and state tax loss carry forwards will expire between 2027 and 2033.

The Company's net operating losses and credits are subject to annual limitations due to ownership change limitations provided by Internal Revenue Code Section 382. At this time the Company does not believe its carryforwards or credits will be materially impacted by such limitations.

In July 2006, the FASB issued Interpretation 48 (codified primarily in ASC 740), which clarifies the accounting for uncertainty in income taxes recognized in the financial statements in accordance with Statement 109 (codified primarily in ASC 740). Interpretation 48 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more-likely-than-not recognition threshold at the effective date to be recognized upon the adoption of Interpretation 48 and in subsequent periods. As a result of the implementation, the Company has analyzed its tax positions and determined that no reserve is necessary at this time.

The Company is subject to taxation in the US and various state jurisdictions. As of December 31, 2013, the Company’s tax years for 2010, 2011 and 2012 are subject to examination by the tax authorities. As of December 31, 2013, the Company is generally no longer subject to US federal, state, or local examinations by tax authorities for years before 2010. Tax year 2009 was open as of December 31, 2012.

FDA Untitled Letter and Related Litigation

Initially, MiMedx processed its tissue allografts in only one form, which was a sheet form. In 2011, MiMedx introduced a micronized form of its sheet allografts.

The FDA has specific regulations governing human cells, tissues and cellular and tissue-based products, or HCT/Ps. An HCT/P is a product containing or consisting of human cells or tissue intended for transplantation into a human patient. If an HCT/P meets the criteria for regulation solely under Section 361 of the Public Health Service Act (so-called “361 HCT/Ps”), no FDA review for safety and effectiveness under a drug, device, or biological product marketing application is required.

MiMedx believes that all of its tissue products qualify as 361 HCT/Ps. On August 28, 2013, however, the FDA issued an Untitled Letter alleging that the Company’s micronized allografts do not meet the criteria for regulation solely under Section 361 of the Public Health Service Act and that, as a result, MiMedx would need a biologics license to lawfully market the micronized products.

After a series of correspondence and conference calls and a meeting with FDA representatives, in December 2013, the FDA clarified the basis for its position regarding the micronized products. Specifically, the FDA explained its belief that “[c]ryo-milling cut, dehydrated amniotic/chorionic membrane results in a micron-sized powder and the loss of the tensile strength and elasticity that are essential characteristics of the original amniotic/chorionic tissue relating to its utility to function as a ‘physical membrane’ (i.e. covering, barrier).” For this reason, the Agency continues to believe that the micronized products are more than minimally manipulated and the products therefore are not eligible for marketing solely under Section 361 of the Public Health Service Act. The Company responded to the FDA that while it does not agree with the Agency’s position, it understands the Agency’s interest in further regulating this emerging technology. Accordingly, the Company has proposed to the FDA that it will pursue the Investigational New Drug (“IND”) and Biologics License Application (“BLA”) process for certain micronized products, and, in parallel, also proposed to enter into negotiations with the FDA on a plan to transition the micronized products to licensed biological products and continue to market the micronized products under specific conditions. The Company has also informed the FDA that it is ready to immediately commence discussions regarding this transition plan. There is no guarantee that the FDA will agree to a transition plan or allow us to continue to market our micronized products while we pursue one or more BLAs. If they do allow us to continue to market our micronized products, they may impose conditions, such as labeling restrictions and compliance with Current Good Manufacturing Practices (“cGMP”). It is also possible that we will be required to recall our micronized products Revenues from micronized products make up about 15% of projected revenues in 2014.

Following the publication of the Untitled Letter from the FDA regarding the Company’s injectable products in September 2013, the trading price of the Company’s stock dropped sharply and several purported class action lawsuits were filed against us and certain of our executive officers asserting violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to the Company’s belief that FDA approval was not required to market its products, including its micronized products. These cases have now all been removed to, and consolidated in, the United States District Court for the Northern District of Georgia. By order dated December 9, 2013, the Court approved the appointment of a lead plaintiff and a lead counsel. A Consolidated Amended Class Action Complaint, containing substantially the same causes of action and claims for relief as the initial complaints, was filed on January 27, 2014. On February 26, 2014, we filed a Motion to Dismiss on various grounds. The plaintiffs' response to the Company's Motion to Dismiss is due March 28, 2014. The Company currently believes that the outcome of this litigation will not have a material adverse impact on our financial position or results of operations.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

We maintain “disclosure controls and procedures” within the meaning of Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act.  Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by the Company in the reports filed under the Exchange Act, such as this Annual Report on Form 10-K, is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms.  Our disclosure controls and procedures include controls and procedures designed to provide reasonable assurance 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 our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and no evaluation of controls and procedures can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.  Management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by Rule 13a-15(b) of the Exchange Act, prior to filing this Annual Report on Form 10-K, 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) as of the end of the period covered by this Annual Report on Form 10-K. Based on their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Annual Report on Form 10-K.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended). Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2013.  In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (1992). Our management has concluded that, as of December 31, 2013, our internal control over financial reporting is effective based on these criteria.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.  Also, projections of any evaluation of the effectiveness of internal controls over financial reporting to future periods are subject to the risk that the controls may become inadequate.

An evaluation was also performed under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of any changes in our internal control over financial reporting that occurred during our last fiscal quarter and that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.  That evaluation did not identify any change in our internal control over financial reporting that occurred during our latest fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Cherry Bekaert LLP, an independent registered accounting firm, as auditors of our financial statements have issued an attestation report on the effectiveness of the Company’s and its subsidiaries’ internal control over financial reporting as of December 31, 2013. Cherry Bekaert LLP's report is included in this report.

RESTRICTED STOCK AGREEMENT

THIS AGREEMENT, entered into as of ____________ (the “Grant Date”) by and between _______________ (the “Participant”) and MiMedx Group, Inc. (the “Company”);

WHEREAS, the Company maintains the MiMedx Group, Inc. Assumed 2006 Incentive Plan (the “Plan”), which is incorporated into and forms a part of this Agreement, and the Participant has been selected by the committee administering the Plan (the “Committee”) to receive a Restricted Stock Award under the Plan;

NOW, THEREFORE, IT IS AGREED, by and between the Company and the Participant, as follows:

1.Terms of Award and Definitions. The following additional terms used in this Agreement shall have the meanings set forth in this Section 1:

(a)Date of Termination. The Participant’s “Date of Termination” shall be the first day occurring on or after the Grant Date on which the Participant is neither employed by the Company, a director of the Company, nor an independent contractor performing services for the Company.

(b)Designated Beneficiary. The “Designated Beneficiary” shall be the beneficiary or beneficiaries designated by the Participant in a writing filed with the Committee in such form and at such time as the Committee shall require.

(c)Restricted Period. A “Restricted Period” is the one year period beginning on the Grant Date and ending on the first anniversary of the Grant Date and the successive one-year periods ending on the second and third anniversaries of the Grant Date.

(d)Restricted Stock. The number of shares of “Restricted Stock” awarded under this Agreement shall be __________shares. Shares of “Restricted Stock” are shares of Stock granted under this Agreement and are subject to the terms of this Agreement and the Plan.

Except where the context clearly implies or indicates the contrary, a word, term, or phrase used in the Plan is similarly used in this Agreement. All other capitalized terms shall have the meaning assigned to such terms in the Plan.

2.Award. The Participant is hereby granted the number of shares of Restricted Stock set forth in Section 1.

3.Deposit of Shares of Restricted Stock. Each certificate issued in respect of shares of Restricted Stock granted under this Agreement shall be registered in the name of the Participant and shall be deposited in a bank designated by the Committee. The grant of Restricted Stock is conditioned upon the Participant endorsing in blank a stock power for the Restricted Stock.

4.Transfer and Forfeiture of Shares.

(a)If the Participant’s Date of Termination (as defined above) does not occur during a Restricted Period, then, at the end of such Restricted Period, the Participant shall become vested in one-third of the shares of Restricted Stock, and shall own such shares free of all restrictions otherwise imposed by this Agreement. A certificate reflecting the number of shares of Stock so vested shall be delivered to the Participant as soon as practicable after the end of such Restricted Period, but in any event no later than the fifteenth (15^th) day following the end of the applicable Restricted Period. Notwithstanding the foregoing, in the event a Change in Control, as defined in the Plan, occurs on or prior to the third anniversary of the Grant Date and prior to the Participant’s Date of Termination, all of the Participant’s shares of Restricted Stock shall immediately vest and become non-forfeitable.

(b)If the Participant’s Date of Termination occurs prior to the end of a Restricted Period, the Participant shall forfeit any unvested Restricted Stock as of the Participant’s Date of Termination.

(c)Otherwise, shares of Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered until the Participant is vested in the shares.

5.Withholding. Participant must make arrangements, satisfactory to the Company, for satisfaction of any applicable foreign, federal, state or local withholding requirements related to the receipt of Restricted Stock or the lapse of restrictions thereon. If no alternative arrangements are made, the Company may withhold Restricted Stock to satisfy such withholding requirements.

6.Heirs and Successors.

(a)This Agreement shall be binding upon, and inure to the benefit of, the Company and the Participant and their respective successors and assigns.

(b)If any rights exercisable by the Participant or benefits deliverable to the Participant under this Agreement have not been exercised or delivered, respectively, at the time of the Participant’s death, such rights shall be exercisable by the Designated Beneficiary, and such benefits shall be delivered to the Designated Beneficiary, in accordance with the provisions of this Agreement and the Plan.

(c)If a deceased Participant has failed to designate a beneficiary, or if the Designated Beneficiary does not survive the Participant, any rights that would have been exercisable by the Participant and any benefits distributable to the Participant shall be exercised by or distributed to the legal representative of the estate of the Participant.

(d)If a deceased Participant has designated a beneficiary but the Designated Beneficiary dies before the Designated Beneficiary’s exercise of all rights under this Agreement or before the complete distribution of benefits to the Designated Beneficiary under this Agreement, then any rights that would have been exercisable by the Designated Beneficiary shall be exercised by the legal representative of the estate of the Designated Beneficiary, and any benefits distributable to the Designated Beneficiary shall be distributed to the legal representative of the estate of the Designated Beneficiary.

7.Substituted or Additional Shares. If, from time to time during the term of this Agreement, there is any stock split-up, stock dividend, stock distribution or other reclassification of the Company’s Common Stock, any and all new, substituted or additional securities to which the Participant is entitled by reason of his or her ownership of the Restricted Stock shall be immediately subject to the terms of this Agreement.

8.Plan Governs. Notwithstanding anything in this Agreement to the contrary, the terms of this Agreement shall be subject to, and governed by, the terms of the Plan, a copy of which is enclosed with this Agreement; and this Agreement is subject to all interpretations, amendments, rules and regulations promulgated by the Committee from time to time pursuant to the Plan. In the event of any conflict between the terms of the Plan and this Agreement, the terms of the Plan shall govern.

9.Charges, Taxes and Expenses. The issuance of certificates for shares of Restricted Stock shall be made without charge to the Participant for any transfer tax or other such expense imposed or incurred with respect to the issuance of such certificates, all of which taxes and expenses shall be paid by the Company.

10.Governing Law. The governing laws applicable to the Plan shall govern this Agreement.

[1] On January 5, 2011, the Company acquired Surgical Biologics, LLC. As a result, the Company recorded intangible assets for Customer & Supplier Relationships of $3,761,000, Patents & Know-How of $7,690,000, Licenses of $13,000, Trade Names & Trademarks of $1,008,000 and In-Process Research & Development of $25,000. During 2013 an additional $108,910 of costs associated with patents granted during the year were capitalized and included in Patents & Know- How subject to amortization.

[2] On September 1, 2005, we acquired a license from SaluMedica, LLC (SaluMedica) in the original amount of $2,399,000 for the use of certain developed technologies related to spine repair. This license was acquired through the acquisition of SpineMedica Corp. In 2012, we booked an impairment charge related to this asset of $851,676. In the fourth quarter of 2013, the Company made a decision to discontinue marketing the HydroFix® product line and fully impaired the asset. There was no charge to Operations as the asset was fully amortized.

[3] On March 31, 2008, the Company entered into a license agreement for the use of certain developed technologies related to surgical sheets made of polyvinyl alcohol cryogel in the original amount of $2,667,000. In 2012, we booked an impairment charge related to this asset of $946,819. In the fourth quarter of 2013, the Company made a decision to discontinue marketing the HydroFix® product line and fully impaired the asset. This resulted in an impairment charge of $368,102 which is included in the Company's Statement of Operations.

[4] On January 29, 2007, the Company acquired a license from Shriners Hospitals for Children and University of South Florida Research Foundation, Inc. in the amount of $996,000. Within 30 days after the receipt by the Company of approval by the FDA allowing the sale of the first licensed product, the Company is required to pay an additional $200,000 to the licensor. Due to its contingent nature, this amount is not recorded as a liability. The Company will also be required to pay a royalty of 3% on all commercial sales revenue from the licensed products. The Company is also obligated to pay a $50,000 minimum annual royalty payment over the life of the license. As of December 31, 2013, this license had a remaining net book value of approximately $309,000.

[5] Capitalized external legal and other registration costs in connection with internally developed tissue-based patents that are pending. Once issued, the costs associated with a given patent will be included in Patents & Know-How under intangible assets subject to amortization.

Stock Incentive Plans

The Company has three share-based compensation plans: the MiMedx Group, Inc. Assumed 2006 Stock Incentive Plan (the “2006 Plan”), the MiMedx Inc. 2007 Assumed Stock Plan (the “Assumed 2007 Plan”) and the MiMedx Group Inc. Amended and Restated Assumed 2005 Stock Plan (the “Assumed 2005 Plan”) which provide for the granting of qualified incentive and non-qualified stock options, stock appreciation awards and restricted stock awards to employees, directors, consultants and advisors. The awards are subject to a vesting schedule as set forth in each individual agreement. The Company intends to use only the 2006 Plan to make future grants. The number of assumed options under the Assumed 2005 Plan and Assumed 2007 Plan outstanding at December 31, 2013, totaled 375,000.  On March 6, 2013, the Board of Directors approved 6,000,000 additional shares to be made available under the 2006 Plan, bringing the maximum number of shares of common stock which can be issued under the 2006 Plan to 22,500,000 at December 31, 2013. The shareholders approved the increase on May 9, 2013.

A summary of the status of the Company’s unvested stock options as of December 31 is presented below:

	2013
Unvested Stock Options	Number of Shares		Weighted- Average Grant Date Fair Value
Unvested at January 1, 2013	8,377,538		$	0.96
Granted	4,021,000		$	3.08
Cancelled/expired	(265,002	)	$	2.14
Vested	(3,565,308	)	$	0.94
Unvested at December 31, 2013	8,568,228		$	1.94

Total unrecognized compensation expense at December 31, 2013, was approximately $12,052,935 and will be charged to expense through February 2016.

The fair value of the options granted was estimated on the date of grant using the Black-Scholes-Merton option-pricing model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate.  Expected volatilities are based on historical volatility of peer companies and other factors estimated over the expected term of the options.  The term of employee options granted is derived using the “simplified method” which computes expected term as the average of the sum of the vesting term plus the contract term.  The simplified method was used due to the Company’s lack of sufficient historical data to provide a reasonable basis upon which to estimate the expected term due to the limited period of time its equity shares have been publicly traded.  The term for non-employee options is generally based upon the contractual term of the option.  The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term or contractual term as described.

The assumptions used in calculating the fair value of options using the Black-Scholes-Merton option-pricing model are set forth in the following table:

	Year ended December 31,
	2013	2012	2011
Expected volatility	61.41 - 64.77%	45.7 - 64.3%	57.3-58.1%
Expected life (in years)	6	6	6
Expected dividend yield	—	—	—
Risk-free interest rate	0.85 - 1.88%	0.62 - 1.77%	0.86 - 2.24%

The weighted-average grant date fair value for options granted during the years ended December 31, 2013, 2012 and 2011 were approximately $3.08, $1.07, and $0.63, respectively.

Restricted Stock Awards

Following is summary information for restricted stock awards for the years ended 2013 and 2012. There were no restricted stock awards in 2011 and prior years. Shares vest over a one to three year period. As of December 31, 2013, there was approximately $2,471,000 of total unrecognized stock-based compensation related to time-based, nonvested restricted stock.  That expense is expected to be recognized on a straight-line basis over a weighted-average period of 2.5 years.

	Number of Shares		Weighted-Average Grant Date Fair Value

Warrants may be exercised in whole or in part by:

• notice given by the holder accompanied by payment of an amount equal to the warrant exercise price multiplied by the number of warrant shares being purchased; or

• if permitted by the applicable warrant election by the holder to exchange the warrant (or portion thereof) for that number of shares equal to the product of (a) the number of shares issuable upon exercise of the warrant (or portion) and (b) a fraction, (x) the numerator of which is the market price of the shares at the time of exercise minus the warrant exercise price per share at the time of exercise and (y) the denominator of which is the market price per share at the time of exercise.

These warrants are not mandatorily redeemable, and do not obligate the Company to repurchase its equity shares by transferring assets or issuing a variable number of shares.

The warrants require that the Company deliver shares as part of a physical settlement or, if permitted by the applicable warrant a net-share settlement, at the option of the holder, and do not provide for a net-cash settlement.

All of our warrants are classified as equity as of December 31, 2013, December 31, 2012, and December 31, 2011.

FDA Untitled Letter and Related Litigation

Initially, MiMedx processed its tissue allografts in only one form, which was a sheet form. In 2011, MiMedx introduced a micronized form of its sheet allografts.

The FDA has specific regulations governing human cells, tissues and cellular and tissue-based products, or HCT/Ps. An HCT/P is a product containing or consisting of human cells or tissue intended for transplantation into a human patient. If an HCT/P meets the criteria for regulation solely under Section 361 of the Public Health Service Act (so-called “361 HCT/Ps”), no FDA review for safety and effectiveness under a drug, device, or biological product marketing application is required.

MiMedx believes that all of its tissue products qualify as 361 HCT/Ps. On August 28, 2013, however, the FDA issued an Untitled Letter alleging that the Company’s micronized allografts do not meet the criteria for regulation solely under Section 361 of the Public Health Service Act and that, as a result, MiMedx would need a biologics license to lawfully market the micronized products.

After a series of correspondence and conference calls and a meeting with FDA representatives, in December 2013, the FDA clarified the basis for its position regarding the micronized products. Specifically, the FDA explained its belief that “[c]ryo-milling cut, dehydrated amniotic/chorionic membrane results in a micron-sized powder and the loss of the tensile strength and elasticity that are essential characteristics of the original amniotic/chorionic tissue relating to its utility to function as a ‘physical membrane’ (i.e. covering, barrier).” For this reason, the Agency continues to believe that the micronized products are more than minimally manipulated and the products therefore are not eligible for marketing solely under Section 361 of the Public Health Service Act. The Company responded to the FDA that while it does not agree with the Agency’s position, it understands the Agency’s interest in further regulating this emerging technology. Accordingly, the Company has proposed to the FDA that it will pursue the Investigational New Drug (“IND”) and Biologics License Application (“BLA”) process for certain micronized products, and, in parallel, also proposed to enter into negotiations with the FDA on a plan to transition the micronized products to licensed biological products and continue to market the micronized products under specific conditions. The Company has also informed the FDA that it is ready to immediately commence discussions regarding this transition plan. There is no guarantee that the FDA will agree to a transition plan or allow us to continue to market our micronized products while we pursue one or more BLAs. If they do allow us to continue to market our micronized products, they may impose conditions, such as labeling restrictions and compliance with Current Good Manufacturing Practices (“cGMP”). It is also possible that we will be required to recall our micronized products Revenues from micronized products make up about 15% of projected revenues in 2014.

Following the publication of the Untitled Letter from the FDA regarding the Company’s injectable products in September 2013, the trading price of the Company’s stock dropped sharply and several purported class action lawsuits were filed against us and certain of our executive officers asserting violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to the Company’s belief that FDA approval was not required to market its products, including its micronized products. These cases have now all been removed to, and consolidated in, the United States District Court for the Northern District of Georgia. By order dated December 9, 2013, the Court approved the appointment of a lead plaintiff and a lead counsel. A Consolidated Amended Class Action Complaint, containing substantially the same causes of action and claims for relief as the initial complaints, was filed on January 27, 2014. On February 26, 2014, we filed a Motion to Dismiss on various grounds. The plaintiffs' response to the Company's Motion to Dismiss is due March 28, 2014. The Company currently believes that the outcome of this litigation will not have a material adverse impact on our financial position or results of operations.

Income Taxes

Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Significant components of the Company’s deferred tax assets and liabilities are as follows:

	December 31,
	2013			2012
Deferred tax assets and liabilities:
Accrued liabilities	$	1,404,000		$	(125,000	)
Beneficial conversion feature on convertible financial instruments	—			(449,000		)
Intangible assets	1,021,000			1,117,000
Property and equipment	(507,000		)	89,000
R&D Credit Carryforward	1,369,000			1,407,356
Stock Compensation	2,151,000			213,000
Adjust accrued earn-out liability	—			567,947
Charitable Contributions	1,000			3,000
Patent fees	142,000			6,000
Net operating loss	14,663,000			15,539,000
Net deferred tax assets	$	20,244,000		$	18,368,303
Valuation allowance	(20,244,000		)	(18,368,303		)
	$	—		$	—

The reconciliation of the Federal statutory income tax rate of 34% to the effective rate is as follows:

	December 31,
	2013		2012
Federal statutory rate	34.00	%	34.00	%
State taxes, net of federal benefit	(2.48	)%	3.40	%
Permanent items & other	12.73	%	0.65	%
Valuation allowance	(46.73	)%	(38.05	)%
	(2.48	)%	—	%

Income taxes are based on estimates of the annual effective tax rate and evaluations of possible future events and transactions and may be subject to subsequent refinement or revision.

Certain items of income and expense are not reported in tax returns and financial statements in the same year. The tax effect of such temporary differences is reported as deferred income taxes. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefit that, based on available evidence, is not expected to be realized. The Company establishes a valuation allowance for deferred tax assets for which realization is not likely. At December 31, 2013, the Company had a valuation allowance of $20,244,000 recorded against the benefit of certain deferred tax assets. In assessing the recoverability of our deferred tax assets, we analyzed all evidence, both positive and negative. We considered, among other things, our deferred tax liabilities, our historical earnings and losses, projections of future income, and tax-planning strategies available to us in the relevant jurisdiction.

At December 31, 2013, we have income tax net operating loss ("NOL") carry forwards for federal and state purposes of $36,861,000 and $30,036,000, respectively. The Company has recorded a deferred tax asset for both federal and state income taxes of $12,533,000 and $2,130,000, respectively. If not utilized, the federal and state tax loss carry forwards will expire between 2027 and 2033.

The Company's net operating losses and credits are subject to annual limitations due to ownership change limitations provided by Internal Revenue Code Section 382. At this time the Company does not believe its carryforwards or credits will be materially impacted by such limitations.

In July 2006, the FASB issued Interpretation 48 (codified primarily in ASC 740), which clarifies the accounting for uncertainty in income taxes recognized in the financial statements in accordance with Statement 109 (codified primarily in ASC 740). Interpretation 48 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more-likely-than-not recognition threshold at the effective date to be recognized upon the adoption of Interpretation 48 and in subsequent periods. As a result of the implementation, the Company has analyzed its tax positions and determined that no reserve is necessary at this time.

The Company is subject to taxation in the US and various state jurisdictions. As of December 31, 2013, the Company’s tax years for 2010, 2011 and 2012 are subject to examination by the tax authorities. As of December 31, 2013, the Company is generally no longer subject to US federal, state, or local examinations by tax authorities for years before 2010. Tax year 2009 was open as of December 31, 2012.

From December 27 to December 31, 2011, the Company sold 5% Convertible Senior Secured Promissory Notes (the “Notes”) to individual accredited investors for aggregate proceeds of $5,000,000.  The aggregate proceeds included $500,000 of Notes sold to the Company’s Chairman of the Board and CEO.  In total, the principal of the Notes were convertible into up to 5,000,000 shares of common stock of the Company (“Common Stock”) plus accrued but unpaid interest at $1.00 per share at any time upon the election of the holder of the note.

In conjunction with the sale of the Notes, the Company incurred a placement fee of $32,800 and issued 42,400 common stock warrants to the placement agents at an exercise price of $1.09 per share.  The warrants expire in 5 years.  The fair value of the warrants was determined to be approximately $15,000 using the Black-Scholes-Merton valuation technique.  The total direct costs of approximately $47,800 were recorded as deferred financing costs and were amortized over the term of the Notes using the effective interest method.  Further, the placement agent warrants are classified in stockholders’ equity because they achieved all of the requisite conditions for equity classification in accordance with GAAP.

During the months of January and February 2013, all holders of the Notes converted their interest in this obligation to shares of MiMedx common stock.  The total amount of debt plus accrued interest that was exchanged was approximately $5,272,000.  In conjunction with this exchange, approximately 5,272,000 shares of the Company’s common stock were issued in full satisfaction of this obligation.  Included in this total are 532,260 shares representing the Chief Executive Officer’s conversion of his Note.  This also resulted in the acceleration of amortization of debt discount and total interest expense of approximately $1,328,000 during the year ended December 31, 2013.

Line of Credit

On May 17, 2013, the Company and Bank of America, N.A. (the “Lender”) entered into a Loan Agreement (the “Loan Agreement”).  The Loan Agreement provides the Company with a secured revolving line of credit (the “Revolving Line of Credit”) of up to $3,000,000, and includes a sub-limit of up to $1,000,000 for the issuance of letters of credit.  The Revolving Line of Credit is secured by the Company's accounts receivable and inventory.  The Company intends to utilize the Revolving Line of Credit for general corporate purposes. As of the date of this filing, the Company has not made any draws under the Revolving Line of Credit.

Accrued interest with respect to principal amounts outstanding under the Loan Agreement is payable in arrears on a monthly basis calculated at the rate of LIBOR plus two percent (2%). The principal amount outstanding under the Loan Agreement and any accrued and unpaid interest are due no later than May 1, 2014, and the Revolving Line of Credit is subject to certain prepayment penalties upon early termination of the Revolving Line of Credit.   The Loan Agreement is subject to renewal by the lender at the end of the term.

The Loan Agreement contains covenants that limit under certain circumstances the ability of the Company to, among other things, merge with or acquire other entities, incur new liens, incur additional indebtedness, sell assets outside of the ordinary course of business, make loans, advances or other extensions of credit or engage in any business activities substantially different from the Company's current business without the Lender's consent. The Loan Agreement also requires the Company to maintain certain financial covenants, including a minimum funded debt to adjusted EBITDA ratio and a minimum fixed charge coverage ratio. The Company is in compliance with these covenants.

(a) On January 29, 2007, the Company acquired a license from Shriners Hospitals for Children and University of South Florida Research Foundation, Inc. in the amount of $996,000.  Within 30 days after the receipt by the Company of approval by the FDA allowing the sale of the first licensed product, the Company is required to pay an additional $200,000 to the licensor.  Due to its contingent nature, this amount is not recorded as a liability. The Company will also be required to pay a royalty of 3% on all commercial sales revenue from the licensed products. The Company is also obligated to pay a $50,000 minimum annual royalty payment over the life of the license. As of December 31, 2013, this license had a remaining net book value of approximately $309,000.

(b) On September 1, 2005, we acquired a license from SaluMedica, LLC (SaluMedica) in the original amount of $2,399,000 for the use of certain developed technologies related to spine repair. This license was acquired through the acquisition of SpineMedica Corp. In 2012, we booked an impairment charge related to this asset of $851,676. In the fourth quarter of 2013, the Company made a decision to discontinue marketing the HydroFix^® product line and fully impaired the asset. There was no charge to Operations as the asset was fully amortized.

(c) On March 31, 2008, the Company entered into a license agreement for the use of certain developed technologies related to surgical sheets made of polyvinyl alcohol cryogel in the original amount of $2,667,000. In 2012, we booked an impairment charge related to this asset of $946,819. In the fourth quarter of 2013, the Company made a decision to discontinue marketing the HydroFix^® product line and fully impaired the asset. This resulted in an impairment charge of $368,102 which is included in the Company's Statement of Operations.

(d) On January 5, 2011, the Company acquired Surgical Biologics, LLC.  As a result, the Company recorded intangible assets for Customer & Supplier Relationships of $3,761,000, Patents & Know-How of $7,690,000, Licenses of $13,000, Trade Names & Trademarks of $1,008,000 and In-Process Research & Development of $25,000.

Earnings Per Share [Abstract]

Net Income (loss) Per Share

Net Income (loss) Per Share

Basic net income (loss) per common share is computed using the weighted-average number of common shares outstanding during the period.  Diluted net loss per common share is computed using the weighted-average number of common and dilutive common equivalent shares from stock options, warrants and convertible debt using the treasury stock method.  For all periods presented, diluted net loss per share is the same as basic net loss per share, as the inclusion of equivalent shares from outstanding common stock options, warrants and convertible debt would be anti-dilutive.

The following table sets forth the computation of basic and diluted net loss per share:

	Year Ended December 31,
	2013			2012			2011

Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2013

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported consolidated statements of operations during the reporting period.  Actual results could differ from those estimates.

Principles of Consolidation

Principles of Consolidation

The accompanying financial statements include the accounts of MiMedx Group, Inc. and its wholly-owned subsidiaries MiMedx, Inc., SpineMedica, LLC, and MiMedx Tissue Services, LLC, formerly known as Surgical Biologics, LLC. All significant inter-company balances and transactions have been eliminated.

Reclassifications

Reclassifications

Certain amounts in the prior year financial statements have been reclassified to conform to the current year financial statement presentation.

Segment Reporting

Segment Reporting

ASC 280, “Segment Reporting” requires use of the “management approach” model for segment reporting.  The management approach model is based on the way a company’s management organizes segments within the company for making operating decisions and assessing performance. The Company determined it has one operating segment.  Disaggregation of the Company’s operating results is impracticable, because the Company’s research and development activities and its assets overlap, and management reviews its business as a single operating segment.  Thus, discrete financial information is not available for more than one operating segment.

Market Concentrations and Credit Risk

Market Concentrations and Credit Risk

The Company places its cash and cash equivalents on deposit with financial institutions in the United States.  In July 2010, the Federal Deposit Insurance Corporation (“FDIC”) increased coverage to $250,000 for substantially all depository accounts. As of December 31, 2013, the Company had cash and cash equivalents of approximately $43,600,000 in excess of the insured amounts.

The Company’s principal market concentration of risk is related to its limited distribution channels.  The Company's revenues include the distribution efforts of several independent companies as well as the Company's internal sales force. Significant revenues are derived from its relationships with two of its distributors, AvKARE, Inc. which sells our products to the Federal government and another distributor that sells our products in certain defined Territories. For the years ended December 31, 2013, 2012 and 2011, AvKARE revenue was 56%, 40%, and 0% of total revenue, respectively. Related receivables for the same time periods were 55%, 53%, and 0%, of total accounts receivable, respectively. For the years ended December 31, 2013, 2012 and 2011, the other distributor's revenue was 10%, 21%, and 19% of total revenue, respectively. Related receivables for the same time periods were 12%, 25%, and 33% of total accounts receivable, respectively.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents include all highly liquid investments with an original maturity of three months or less.

Accounts Receivable

Accounts Receivable

Accounts receivable represent amounts due from customers for which revenue has been recognized.  Generally, the Company does not require collateral or any other security to support its receivables.

Inventories

Inventories

Inventories are valued at the lower of cost or market, using the first–in, first-out (FIFO) method.  Inventory is tracked through Raw Material, WIP, and Finished Good stages as the product progresses through various production steps and stocking locations. Labor and overhead costs are absorbed through the various production processes upon work order closes. Historical yields and normal capacities are utilized in the calculation of production overhead rates.  Reserves for inventory obsolescence are utilized to account for slow-moving inventory as well as inventory no longer needed due to diminished market demand.

Goodwill and Purchased Intangible Assets

Goodwill and Purchased Intangible Assets

Goodwill and purchased intangible assets with indefinite useful lives are not amortized but are tested for impairment at least annually.  The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually at the beginning of its fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable.  For goodwill, the Company performs a two-step impairment test.  In the first step, the Company compares the fair value of the Company to its carrying value.  The Company determines the fair value utilizing the market approach.  Under the market approach, the Company uses its market capitalization which is calculated by taking the Company’s share price times the number of outstanding shares.  If the fair value of the Company exceeds the carrying value of the net assets, goodwill is not impaired, and no further testing is required.  If the fair value of the Company is less than the carrying value, the Company must perform the second step of the impairment test to measure the amount of impairment loss, if any. In the second step, the Company’s value is allocated to all of the assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the Company was being acquired in a business combination.  If the implied fair value of the reporting unit's goodwill is less than the carrying value, the difference is recorded as an impairment loss.

Impairment of Intangible Assets with Finite Lives

Impairment of Intangible Assets with Finite Lives

The Company reviews purchased intangible assets with finite lives for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable using a two-step impairment test. In step one, we determine the sum of the undiscounted future cash flows of the assets based on management's estimates and compare it to the carrying value of the assets. If the carrying amount is greater than the sum of the undiscounted cash flows, then the asset is impaired and step two is required. In step two, the impairment loss is calculated as the difference between the fair value of the assets and the carrying value of the assets.

Our impairment reviews are based on an estimated future cash flow approach that requires significant judgment with respect to future revenue and expense growth rates, selection of appropriate discount rate, asset groupings, and other assumptions and estimates. We use estimates that are consistent with our business plans and a market participant view of the assets being evaluated. Actual results may differ from our estimates.

During the fourth quarter we chose to discontinue the HydroFix^® product line. This action resulted in an impairment charge of approximately $368,000 related to the Licenses for SaluMedica LLC, Spine Repair and Polyvinyl Alcohol Cryogel. This item is included in our Statement of Operations as of for the year ended December 31, 2013. An impairment charge of approximately $1,800,000 had previously been booked in 2012.

Property and Equipment

Property and Equipment

Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives, principally five to seven years.  Leasehold improvements are depreciated on a straight-line basis over the lesser of the estimated useful lives or the life of the lease. The Company is party to various lease arrangements for its facility space and equipment. These arrangements include interest, scheduled rent increases and rent holidays which are included in the determination of minimum lease payments when assessing lease classification, and are included in rent expense on a straight line basis over the lease term. See Notes 5 and 15 for further information regarding capital leases, operating leases and rent expense.

Impairment of Long-lived Assets

Impairment of Long-lived Assets

The Company evaluates the recoverability of its long-lived assets (property and equipment) whenever adverse events or changes in business climate indicate that the expected undiscounted future cash flows from the related assets may be less than previously anticipated.  If the net book value of the related assets exceeds the expected undiscounted future cash flows of the assets, the carrying amount would be reduced to the present value of their expected future cash flows and an impairment loss would be recognized. During the fourth quarter of 2013, we chose to discontinue the HydroFix® product line. This action resulted in a disposal loss of approximately $30,000. This item is included in our Consolidated Statements of Operations for the year ended December 31, 2013, as Selling, General and Administrative expenses.

Grant Income

Grant Income

The Company received a Regional Economic Business Assistance ("REBA") grant in the amount of $250,000 from the State of Georgia to help the Company defray certain expenses and capital expenditures related to the Company's expansion of manufacturing activities in the State.  In order to retain the grant monies the Company was required to add a certain number of full time positions and spend a certain amount on capital and operations expenditures by December 31, 2014. As of December 31, 2013, the Company had satisfied the grant requirements. Accordingly, the Company has recorded the $250,000 as a reduction of Selling, General and Administrative expenses in the accompanying Consolidated Statements of Operations. Previously, this amount was recorded as Deferred Grant Income and was included in Other Liabilities per ASC 450-30 Gain Contingencies.

Debt Instruments with Detachable Warrants and Beneficial Conversion Features

Debt Instruments with Detachable Warrants and Beneficial Conversion Features

According to ASC470-20 "Debt With Conversion and Other Options", proceeds from the sale of convertible debt instruments with stock purchase warrants (detachable call options) shall be allocated to the two elements based upon the relative fair values of the debt instrument without the warrants and of the warrants themselves at the time of issuance.  The portion of the proceeds so allocated to the warrants shall be accounted for as paid-in capital.  The remainder of the proceeds shall be allocated to the debt instrument portion of the transaction.  Also, the embedded beneficial conversion feature present in the convertible instrument shall be recognized separately at issuance by allocating a portion of the proceeds equal to the intrinsic value of that feature to additional paid-in capital.

Revenue Recognition

Revenue Recognition

The Company sells its products primarily through a combination of a direct sales force, independent stocking distributors and third party representatives in the U.S. and independent distributors in international markets.  The Company recognizes revenue when title to the goods and risk of loss transfers to customers, provided there are no material remaining performance obligations required of the Company or any matters of customer acceptance.  In cases where the Company utilizes distributors or ships products directly to the end user, it recognizes revenue according to the shipping terms of the agreement provided all revenue recognition criteria have been met.  A portion of the Company’s revenue is generated from inventory maintained at hospitals or with field representatives.  For these products, revenue is recognized at the time the product has been used or implanted.  The Company records estimated sales returns, discounts and allowances as a reduction of net sales in the same period revenue is recognized.

Research and Development Costs

Research and Development Costs

Research and development costs consist of direct and indirect costs associated with the development of the Company’s technologies.  These costs are expensed as incurred.

Income Taxes

Income Taxes

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that included the enactment date.  Valuation allowances are recorded for deferred tax assets when the recoverability of such assets is not deemed more likely than not.

Uncertain Tax Positions

Uncertain Tax Positions

Tax positions are evaluated in a two-step process.  The Company first determines whether it is more likely than not that a tax position will be sustained upon examination.  If a tax position meets the more-likely-than-not recognition threshold it is then measured to determine the amount of benefit to recognize in the financial statements.  The tax position is measured as the largest amount of benefit that is more than 50% likely of being realized upon ultimate settlement.  The Company classifies gross interest and penalties and unrecognized tax benefits that are not expected to result in payment or receipt of cash within one year as non-current liabilities in the Consolidated Balance Sheets.

Share-based Compensation

Share-based Compensation

The Company follows the provisions of ASC topic 718 “Compensation — Stock compensation”, which requires the use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares of stock or equity instruments (options and warrants).  All awards are amortized on a straight-line basis over their vesting terms.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The respective carrying value of certain on-balance-sheet financial instruments approximated their fair values due to the short-term nature of these instruments. These financial instruments include cash, accounts receivable, accounts payable and accrued expenses. The fair value of the Company’s capital leases approximates its carrying value based upon current rates available to the Company.

The Company records certain financial instruments at fair value, including: cash equivalents and contingent consideration.  The Company may make an irrevocable election to measure other financial instruments at fair value on an instrument-by-instrument basis; although as of December 31, 2013, the Company has not chosen to make any such elections.  Fair value financial instruments are recorded in accordance with the fair value measurement framework.

The Company also measures certain non-financial assets at fair value on a non-recurring basis.  These non-recurring valuations include evaluating assets such as long-lived assets; and non-amortizing intangible assets for impairment; allocating value to assets in an acquired asset group; and applying accounting for business combinations.  The Company uses the fair value measurement framework to value these assets and reports these fair values in the periods in which they are recorded or written down.

The fair value measurement framework includes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair values in their broad levels.  These levels from highest to lowest priority are as follows:

• Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities;

• Level 2: Quoted prices in active markets for similar assets or liabilities or observable prices that are based on inputs not quoted on active markets, but corroborated by market data; and

• Level 3: Unobservable inputs or valuation techniques that are used when little or no market data is available.

The determination of fair value and the assessment of a measurement’s placement within the hierarchy require judgment. Level 3 valuations often involve a higher degree of judgment and complexity.  Level 3 valuations may require the use of various cost, market, or income valuation methodologies applied to unobservable management estimates and assumptions.  Management’s assumptions could vary depending on the asset or liability valued and the valuation method used.  Such assumptions could include: estimates of prices, earnings, costs, actions of market participants, market factors, or the weighting of various valuation methods.  The Company may also engage external advisors to assist it in determining fair value, as appropriate.

Although the Company believes that the recorded fair value of its financial instruments is appropriate, these fair values may not be indicative of net realizable value or reflective of future fair values.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported consolidated statements of operations during the reporting period.  Actual results could differ from those estimates.

Principles of Consolidation

The accompanying financial statements include the accounts of MiMedx Group, Inc. and its wholly-owned subsidiaries MiMedx, Inc., SpineMedica, LLC, and MiMedx Tissue Services, LLC, formerly known as Surgical Biologics, LLC. All significant inter-company balances and transactions have been eliminated.

Reclassifications

Certain amounts in the prior year financial statements have been reclassified to conform to the current year financial statement presentation.

Segment Reporting

ASC 280, “Segment Reporting” requires use of the “management approach” model for segment reporting.  The management approach model is based on the way a company’s management organizes segments within the company for making operating decisions and assessing performance. The Company determined it has one operating segment.  Disaggregation of the Company’s operating results is impracticable, because the Company’s research and development activities and its assets overlap, and management reviews its business as a single operating segment.  Thus, discrete financial information is not available for more than one operating segment.

Market Concentrations and Credit Risk

The Company places its cash and cash equivalents on deposit with financial institutions in the United States.  In July 2010, the Federal Deposit Insurance Corporation (“FDIC”) increased coverage to $250,000 for substantially all depository accounts. As of December 31, 2013, the Company had cash and cash equivalents of approximately $43,600,000 in excess of the insured amounts.

The Company’s principal market concentration of risk is related to its limited distribution channels.  The Company's revenues include the distribution efforts of several independent companies as well as the Company's internal sales force. Significant revenues are derived from its relationships with two of its distributors, AvKARE, Inc. which sells our products to the Federal government and another distributor that sells our products in certain defined Territories. For the years ended December 31, 2013, 2012 and 2011, AvKARE revenue was 56%, 40%, and 0% of total revenue, respectively. Related receivables for the same time periods were 55%, 53%, and 0%, of total accounts receivable, respectively. For the years ended December 31, 2013, 2012 and 2011, the other distributor's revenue was 10%, 21%, and 19% of total revenue, respectively. Related receivables for the same time periods were 12%, 25%, and 33% of total accounts receivable, respectively.

Cash and Cash Equivalents

Cash and cash equivalents include all highly liquid investments with an original maturity of three months or less.

Accounts Receivable

Accounts receivable represent amounts due from customers for which revenue has been recognized.  Generally, the Company does not require collateral or any other security to support its receivables.

Inventories

Inventories are valued at the lower of cost or market, using the first–in, first-out (FIFO) method.  Inventory is tracked through Raw Material, WIP, and Finished Good stages as the product progresses through various production steps and stocking locations. Labor and overhead costs are absorbed through the various production processes upon work order closes. Historical yields and normal capacities are utilized in the calculation of production overhead rates.  Reserves for inventory obsolescence are utilized to account for slow-moving inventory as well as inventory no longer needed due to diminished market demand.

Goodwill and Purchased Intangible Assets

Goodwill and purchased intangible assets with indefinite useful lives are not amortized but are tested for impairment at least annually.  The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually at the beginning of its fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable.  For goodwill, the Company performs a two-step impairment test.  In the first step, the Company compares the fair value of the Company to its carrying value.  The Company determines the fair value utilizing the market approach.  Under the market approach, the Company uses its market capitalization which is calculated by taking the Company’s share price times the number of outstanding shares.  If the fair value of the Company exceeds the carrying value of the net assets, goodwill is not impaired, and no further testing is required.  If the fair value of the Company is less than the carrying value, the Company must perform the second step of the impairment test to measure the amount of impairment loss, if any. In the second step, the Company’s value is allocated to all of the assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the Company was being acquired in a business combination.  If the implied fair value of the reporting unit's goodwill is less than the carrying value, the difference is recorded as an impairment loss.

Impairment of Intangible Assets with Finite Lives

The Company reviews purchased intangible assets with finite lives for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable using a two-step impairment test. In step one, we determine the sum of the undiscounted future cash flows of the assets based on management's estimates and compare it to the carrying value of the assets. If the carrying amount is greater than the sum of the undiscounted cash flows, then the asset is impaired and step two is required. In step two, the impairment loss is calculated as the difference between the fair value of the assets and the carrying value of the assets.

Our impairment reviews are based on an estimated future cash flow approach that requires significant judgment with respect to future revenue and expense growth rates, selection of appropriate discount rate, asset groupings, and other assumptions and estimates. We use estimates that are consistent with our business plans and a market participant view of the assets being evaluated. Actual results may differ from our estimates.

During the fourth quarter we chose to discontinue the HydroFix^® product line. This action resulted in an impairment charge of approximately $368,000 related to the Licenses for SaluMedica LLC, Spine Repair and Polyvinyl Alcohol Cryogel. This item is included in our Statement of Operations as of for the year ended December 31, 2013. An impairment charge of approximately $1,800,000 had previously been booked in 2012.

Property and Equipment

Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives, principally five to seven years.  Leasehold improvements are depreciated on a straight-line basis over the lesser of the estimated useful lives or the life of the lease. The Company is party to various lease arrangements for its facility space and equipment. These arrangements include interest, scheduled rent increases and rent holidays which are included in the determination of minimum lease payments when assessing lease classification, and are included in rent expense on a straight line basis over the lease term. See Notes 5 and 15 for further information regarding capital leases, operating leases and rent expense.

Patent Costs

The Company incurs certain legal and related costs in connection with patent applications for tissue based products and processes. The Company capitalizes such costs to be amortized over the expected life of the patent to the extent that an economic benefit is anticipated from the resulting patent or alternative future use is available to the Company. The Company capitalized approximately $690,000 of patent costs during 2013. There were no patent costs capitalized in 2012 or 2011.

Impairment of Long-lived Assets

The Company evaluates the recoverability of its long-lived assets (property and equipment) whenever adverse events or changes in business climate indicate that the expected undiscounted future cash flows from the related assets may be less than previously anticipated.  If the net book value of the related assets exceeds the expected undiscounted future cash flows of the assets, the carrying amount would be reduced to the present value of their expected future cash flows and an impairment loss would be recognized. During the fourth quarter of 2013, we chose to discontinue the HydroFix® product line. This action resulted in a disposal loss of approximately $30,000. This item is included in our Consolidated Statements of Operations for the year ended December 31, 2013, as Selling, General and Administrative expenses.

Grant Income

The Company received a Regional Economic Business Assistance ("REBA") grant in the amount of $250,000 from the State of Georgia to help the Company defray certain expenses and capital expenditures related to the Company's expansion of manufacturing activities in the State.  In order to retain the grant monies the Company was required to add a certain number of full time positions and spend a certain amount on capital and operations expenditures by December 31, 2014. As of December 31, 2013, the Company had satisfied the grant requirements. Accordingly, the Company has recorded the $250,000 as a reduction of Selling, General and Administrative expenses in the accompanying Consolidated Statements of Operations. Previously, this amount was recorded as Deferred Grant Income and was included in Other Liabilities per ASC 450-30 Gain Contingencies.

Debt Instruments with Detachable Warrants and Beneficial Conversion Features

According to ASC470-20 "Debt With Conversion and Other Options", proceeds from the sale of convertible debt instruments with stock purchase warrants (detachable call options) shall be allocated to the two elements based upon the relative fair values of the debt instrument without the warrants and of the warrants themselves at the time of issuance.  The portion of the proceeds so allocated to the warrants shall be accounted for as paid-in capital.  The remainder of the proceeds shall be allocated to the debt instrument portion of the transaction.  Also, the embedded beneficial conversion feature present in the convertible instrument shall be recognized separately at issuance by allocating a portion of the proceeds equal to the intrinsic value of that feature to additional paid-in capital.

Revenue Recognition

The Company sells its products primarily through a combination of a direct sales force, independent stocking distributors and third party representatives in the U.S. and independent distributors in international markets.  The Company recognizes revenue when title to the goods and risk of loss transfers to customers, provided there are no material remaining performance obligations required of the Company or any matters of customer acceptance.  In cases where the Company utilizes distributors or ships products directly to the end user, it recognizes revenue according to the shipping terms of the agreement provided all revenue recognition criteria have been met.  A portion of the Company’s revenue is generated from inventory maintained at hospitals or with field representatives.  For these products, revenue is recognized at the time the product has been used or implanted.  The Company records estimated sales returns, discounts and allowances as a reduction of net sales in the same period revenue is recognized.

Research and Development Costs

Research and development costs consist of direct and indirect costs associated with the development of the Company’s technologies.  These costs are expensed as incurred.

Income Taxes

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that included the enactment date.  Valuation allowances are recorded for deferred tax assets when the recoverability of such assets is not deemed more likely than not.

Uncertain Tax Positions

Tax positions are evaluated in a two-step process.  The Company first determines whether it is more likely than not that a tax position will be sustained upon examination.  If a tax position meets the more-likely-than-not recognition threshold it is then measured to determine the amount of benefit to recognize in the financial statements.  The tax position is measured as the largest amount of benefit that is more than 50% likely of being realized upon ultimate settlement.  The Company classifies gross interest and penalties and unrecognized tax benefits that are not expected to result in payment or receipt of cash within one year as non-current liabilities in the Consolidated Balance Sheets.

Share-based Compensation

The Company follows the provisions of ASC topic 718 “Compensation — Stock compensation”, which requires the use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares of stock or equity instruments (options and warrants).  All awards are amortized on a straight-line basis over their vesting terms.

Fair Value of Financial Instruments

The respective carrying value of certain on-balance-sheet financial instruments approximated their fair values due to the short-term nature of these instruments. These financial instruments include cash, accounts receivable, accounts payable and accrued expenses. The fair value of the Company’s capital leases approximates its carrying value based upon current rates available to the Company.

Fair Value Measurements

The Company records certain financial instruments at fair value, including: cash equivalents and contingent consideration.  The Company may make an irrevocable election to measure other financial instruments at fair value on an instrument-by-instrument basis; although as of December 31, 2013, the Company has not chosen to make any such elections.  Fair value financial instruments are recorded in accordance with the fair value measurement framework.

The Company also measures certain non-financial assets at fair value on a non-recurring basis.  These non-recurring valuations include evaluating assets such as long-lived assets; and non-amortizing intangible assets for impairment; allocating value to assets in an acquired asset group; and applying accounting for business combinations.  The Company uses the fair value measurement framework to value these assets and reports these fair values in the periods in which they are recorded or written down.

The fair value measurement framework includes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair values in their broad levels.  These levels from highest to lowest priority are as follows:

• Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities;

• Level 2: Quoted prices in active markets for similar assets or liabilities or observable prices that are based on inputs not quoted on active markets, but corroborated by market data; and

• Level 3: Unobservable inputs or valuation techniques that are used when little or no market data is available.

The determination of fair value and the assessment of a measurement’s placement within the hierarchy require judgment. Level 3 valuations often involve a higher degree of judgment and complexity.  Level 3 valuations may require the use of various cost, market, or income valuation methodologies applied to unobservable management estimates and assumptions.  Management’s assumptions could vary depending on the asset or liability valued and the valuation method used.  Such assumptions could include: estimates of prices, earnings, costs, actions of market participants, market factors, or the weighting of various valuation methods.  The Company may also engage external advisors to assist it in determining fair value, as appropriate.

Although the Company believes that the recorded fair value of its financial instruments is appropriate, these fair values may not be indicative of net realizable value or reflective of future fair values.

The Company considers the applicability and impact of all Accounting Standards Updates "ASUs". For the year ended December 31, 2013, and through the date of this report, all ASUs issued, effective and not yet effective, were assessed and determined to be either not applicable or are expected to have minimal impact on our financial position or results of operations.
