EMCORE Corporation

Notes to our Condensed Consolidated Financial Statements

NOTE 1. Description of Business

Business Overview

EMCORE Corporation (referred to herein, together with its subsidiaries, as the “Company,” “we,” “our,” or “EMCORE”) was established in 1984 as a New Jersey corporation. The Company became publicly traded in 1997 and is listed on The Nasdaq Stock Market under the ticker symbol EMKR. EMCORE is a leading provider of sensors for navigation in the Aerospace and Defense market as well as a manufacturer of lasers and optical subsystems for use in the cable TV industry. EMCORE pioneered the linear fiber optic transmission technology that enabled the world’s first delivery of Cable TV (“CATV”) directly on fiber, and today is a leading provider of advanced Mixed-Signal Optics products that enable communications systems and service providers to meet growing demand for increased bandwidth and connectivity. The Mixed-Signal Optics technology at the heart of our broadband communications products is shared with our fiber optic gyros and inertial sensors to provide the aerospace and defense markets with state-of-the-art navigation systems technology. With the acquisition of Systron Donner Inertial, Inc. (“SDI”), a navigation systems provider with a scalable, chip-based platform for higher volume gyro applications utilizing Quartz MEMS technology, in June 2019, EMCORE further expanded its portfolio of gyros and inertial sensors with SDI’s quartz MEMS gyro and accelerometer technology. EMCORE has fully vertically-integrated manufacturing capability through our indium phosphide compound semiconductor wafer fabrication facility at our headquarters in Alhambra, CA, and through our quartz processing and sensor manufacturing facility in Concord, CA. These facilities support EMCORE’s vertically-integrated manufacturing strategy for quartz and fiber optic gyro products, for navigation systems, and for our chip, laser, transmitter, and receiver products for broadband applications. With both analog and digital circuits on multiple chips, or even a single chip, the value of Mixed-Signal device solutions is often substantially greater than traditional digital applications and requires a specialized expertise held by EMCORE which is unique in the optics industry.

Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim information, and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by U.S. GAAP for annual financial statements. In our opinion, the interim financial statements reflect all adjustments, which are all normal recurring adjustments, that are necessary to provide a fair presentation of the financial results for the interim periods presented. Operating results for interim periods are not necessarily indicative of results that may be expected for an entire fiscal year. The condensed consolidated balance sheet as of September 30, 2020 has been derived from the audited consolidated financial statements as of such date. For a more complete understanding of our business, financial position, operating results, cash flows, risk factors and other matters, please refer to our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.

Significant Accounting Policies and Estimates

Our significant accounting policies are detailed in “Note 2 - Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the year ended September 30, 2020. There have been no significant changes to our accounting policies during the six months ended March 31, 2021. The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, as of the date of the financial statements, and the reported amounts of revenue and expenses during the reported period. If these estimates differ significantly from actual results, the impact to the condensed consolidated financial statements may be material. There have been no material changes in our critical accounting policies and estimates from those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. Please refer to Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020 for a discussion of our critical accounting policies and estimates.

NOTE 2. Recent Accounting Pronouncements

(a)New Accounting Updates Recently Adopted

•In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the way entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net earnings. The new standard is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. The new standard was effective for our fiscal year beginning October 1, 2020. We adopted the new standard on October 1, 2020, and it did not have a material impact on the condensed consolidated financial statements.

(b)Recent Accounting Standards or Updates Not Yet Effective

•In March 2020, the FASB issued ASU 2019-12 Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The new standard is effective for annual periods beginning after December 15, 2020, including interim periods within those annual periods. The new standard will be effective for our fiscal year beginning October 1, 2021 and early adoption is permitted. The Company is currently evaluating the new guidance to determine the impact it may have on the condensed consolidated financial statements and related disclosures.

NOTE 3. Cash, Cash Equivalents and Restricted Cash

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the unaudited consolidated balance sheets that sum to the total of the same amounts shown in the unaudited statements of consolidated cash flows:

Table of Contents

NOTE 4. Fair Value Accounting

Accounting Standards Codification Topic 820 (“ASC 820”), Fair Value Measurement, establishes a valuation hierarchy for disclosure of the inputs to valuation techniques used to measure fair value. This standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

•Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

•Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly, through market corroboration, for substantially the full term of the financial instrument.

•Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets or liabilities at fair value.

Classification of an asset or liability within this hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs.

Cash consists primarily of bank deposits or highly liquid short-term investments with a maturity of three months or less at the time of purchase. Restricted cash represents temporarily restricted deposits held as compensating balances against short-term borrowing arrangements. Cash, cash equivalents and restricted cash are based on Level 1 measurements.

The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, contract assets, other current assets, and accounts payable approximate fair value because of the short maturity of these instruments.

NOTE 5. Accounts Receivable

The components of accounts receivable consisted of the following:

NOTE 9. Credit Facilities and Debt

Credit Facilities

On November 11, 2010, we entered into a Credit and Security Agreement (as amended to date, the “Credit Facility”) with Wells Fargo Bank, N.A. The Credit Facility is secured by the Company’s assets and is subject to a borrowing base formula based on the Company’s eligible accounts receivable, inventory, and machinery and equipment accounts.

The Credit Facility matures in November 2021 and currently provides us with a revolving credit line of up to $15.0 million, subject to a borrowing base formula, that can be used for working capital requirements, letters of credit, acquisitions, and other general corporate purposes subject to a requirement, for certain specific uses, that the Company has liquidity of at least $25.0 million after such use. The Credit Facility requires us to maintain (a) liquidity of at least $10.0 million and (b) excess availability of at least $1.0 million.

As of March 31, 2021, there was no amount outstanding under this Credit Facility and the Company was in compliance with all financial covenants. Also, as of March 31, 2021, the Credit Facility had approximately $0.5 million reserved for one outstanding stand-by letter of credit and $13.4 million available for borrowing.

Table of Contents

Debt

On May 3, 2020, the Company entered into a Paycheck Protection Program Promissory Note and Agreement (the “PPP Loan Agreement”) with Wells Fargo Bank, N.A. under the Paycheck Protection Program (“PPP”) established under the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) to receive loan proceeds of approximately $6.5 million (the “PPP Loan”), which the Company received on May 6, 2020.

The PPP Loan matures on May 3, 2022 and bears interest at a fixed rate of 1.00% per annum, payable monthly. Monthly payments in the amount of $273,160 will be due and payable beginning at such time as is in accordance with the terms of the Paycheck Protection Flexibility Act of 2020 and continuing each month thereafter until maturity of the PPP Loan. There is no prepayment penalty. Under the terms of the PPP, all or a portion of the principal may be forgiven if the PPP Loan proceeds are used for qualifying expenses as described in the CARES Act, such as payroll costs, benefits, rent, and utilities. With respect to any portion of the PPP Loan that is not forgiven, the PPP Loan will be subject to customary provisions for a loan of this type, including customary events of default relating to, among other things, payment defaults and breaches of the provisions of the PPP Loan Agreement. The Company applied for forgiveness of the PPP Loan during the three months ended March 31, 2021, but it can make no assurance that forgiveness will be granted in part or in whole. As of March 31, 2021, $1.9 million is recorded in current liabilities and $4.6 million is recorded in long-term liabilities on the Company’s condensed consolidated balance sheet.

NOTE 10. Income and Other Taxes

During the three months ended March 31, 2021 and 2020, the Company recorded income tax (expense) benefit of approximately $(82,000) and $55,000, respectively. Income tax expense for the three months ended March 31, 2021 and 2020 is composed primarily of state tax expense. The increase in income tax expense is driven by the State of California's temporary suspension of net operating loss ("NOL") utilization.

During the six months ended March 31, 2021 and 2020, the Company recorded income tax (expense) benefit of approximately $(208,000) and $41,000, respectively. Income tax expense for the six months ended March 31, 2021 and 2020 is composed primarily of state tax expense. The increase in income tax expense is driven by the State of California’s temporary suspension of NOL utilization.

For the three months ended March 31, 2021 and 2020 the effective tax rate on continuing operations was 1.9% and 0.2%, respectively. The higher tax rate for the three months ended March 31, 2021 is primarily driven by the State of California's temporary suspension of NOL utilization.

For the six months ended March 31, 2021 and 2020, the effective tax rate on continuing operations was 2.9% and 0.1%, respectively. The increased tax rate for the six months ended March 31, 2021 is primarily driven by the State of California’s temporary suspension of NOL utilization.

The Company uses estimates to forecast the results from continuing operations for the current fiscal year as well as permanent differences between book and tax accounting.

We have not provided for income taxes on non-U.S. subsidiaries’ undistributed earnings as of March 31, 2021 because we plan to indefinitely reinvest the unremitted earnings of our non-U.S. subsidiaries and all of our non-U.S. subsidiaries historically have negative earnings and profits.

All deferred tax assets have a full valuation allowance at March 31, 2021. On a quarterly basis, the Company evaluates the positive and negative evidence to assess whether the more likely than not criteria has been satisfied in determining whether there will be further adjustments to the valuation allowance.

During the three and six months ended March 31, 2021 and 2020, there were no material increases or decreases in unrecognized tax benefits. As of March 31, 2021 and September 30, 2020, we had approximately $0.6 million of interest and penalties and $0.4 million of uncertain tax benefit reserved and accrued for as tax liabilities on our balance sheet. We expect that $1.0 million of uncertain tax benefit including interest and penalties will be settled within the next 12 months, which will impact the effective tax rate. Interest that is accrued on tax liabilities is recorded within interest expense on the condensed consolidated statements of operations.

NOTE 11. Commitments and Contingencies

Indemnifications: We have agreed to indemnify certain customers against claims of infringement of intellectual property rights of others in our sales contracts with these customers. Historically, we have not paid any claims under these customer indemnification obligations. We enter into indemnification agreements with each of our directors and executive officers pursuant to which we agree to indemnify them for certain potential expenses and liabilities arising from their status as a director or executive officer of the Company. We maintain directors and officers insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and executive officers in certain circumstances. It is not possible to determine the aggregate maximum potential loss under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular claim.

Legal Proceedings: We are subject to various legal proceedings, claims, and litigation, either asserted or unasserted, that arise in the ordinary course of business. The outcome of these matters is currently not determinable and we are unable to estimate a range of loss, should a loss occur, from these proceedings. The ultimate outcome of legal proceedings involves judgments, estimates and inherent uncertainties and the results of these matters cannot be predicted with certainty. Professional legal fees are expensed when incurred. We accrue for contingent losses when such losses are probable and reasonably estimable. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information. Should we fail to prevail in any legal matter or should several legal matters be resolved against the Company in the same reporting period, then the financial results of that particular reporting period could be materially affected.

a) Intellectual Property Lawsuits

We protect our proprietary technology by applying for patents where appropriate and, in other cases, by preserving the technology, related know-how and information as trade secrets. The success and competitive position of our product lines are impacted by our ability to obtain intellectual property protection for our research and development efforts. We have, from time to time, exchanged correspondence with third parties regarding the assertion of patent or other intellectual property rights in connection with certain of our products and processes.

b) Resilience Litigation

In February 2021, Resilience Capital (“Resilience”) filed a complaint against us with the Delaware Chancery Court containing claims arising from the February 2020 sale of SDI’s real property (the “Concord Property Sale”) located in Concord, California (the “Concord Real Property”) to Eagle Rock Holdings, LP (“Buyer”) and that certain Single-Tenant Triple Net Lease, dated as of February 10, 2020, entered into by and between SDI and the Buyer, pursuant to which SDI leased from the Buyer the Concord Real Property for a 15 year term. The Resilience complaint seeks, among other items, (i) a declaration that the Concord Property Sale included a non-cash component; (ii) a decree requiring us and Resilience to follow the appraisal requirements set forth in that certain Purchase and Sale Agreement (the "SDI Purchase Agreement"), dated as of June 7, 2019, by and among EMCORE Corporation, The Resilience Fund IV, L.P., The Resilience Fund IV-A, L.P., Aerospace Newco Holdings, Inc. and Ember Acquisition Sub, Inc.; (iii) recovery of Resilience’s costs and expenses; and (iv) pre- and post-judgment interest.

In April 2021, we filed with the Delaware Chancery Court our answer to the Resilience complaint and counterclaims against Resilience, in which we are seeking, among other items, (i) dismissal of the Resilience complaint and/or granting of judgment in favor of EMCORE with respect to the Resilience complaint, (ii) entering final judgment against Resilience awarding damages to us for Resilience’s fraud and breaches of the SDI Purchase Agreement in an amount to be proven at trial and not less than $1,565,000, (iii) a judicial determination of the respective rights and duties of us and Resilience under the SDI Purchase Agreement, (iv) an award to us of costs and expenses and (v) pre- and post-judgment interest. We believe that the claims made by Resilience in its complaint are without merit and we intend to vigorously defend ourselves against them.

NOTE 12. Equity

Equity Plans

We provide long-term incentives to eligible officers, directors, and employees in the form of equity-based awards. We maintain three equity incentive compensation plans, collectively described as our “Equity Plans”:

•the 2010 Equity Incentive Plan,

•the 2012 Equity Incentive Plan, and

Table of Contents

•the 2019 Equity Incentive Plan.

We issue new shares of common stock to satisfy awards issued under our Equity Plans. In March 2021, our shareholders approved the Amended and Restated EMCORE Corporation 2019 Equity Incentive Plan, which was adopted, subject to shareholder approval, by the Company’s Board of Directors in December 2020 and increased the maximum number of shares of the Company’s common stock that may be issued or transferred pursuant to awards under the 2019 Equity Incentive Plan by an additional 2,138,000 shares.

401(k) Plan

We have a savings plan that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under this savings plan, participating employees may defer a portion of their pretax earnings, up to the Internal Revenue Service annual contribution limit. Since June 2015, all employer contributions are made in cash. During each of the three months ended March 31, 2021 and 2020, our matching contribution in cash was approximately $0.3 million. During each of the six months ended March 31, 2021 and 2020, our matching contribution in cash was approximately $0.6 million and $0.5 million, respectively.

Income (Loss) Per Share

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

Net income (loss) per fully diluted share	$	0.13	$	(0.18)	$	0.21	$	(0.22)

Weighted average antidilutive options, unvested restricted stock units and awards, unvested performance stock units and ESPP shares excluded from the computation	1,536		2,161		1,331		1,704

Table of Contents

Basic earnings per share is computed by dividing net income (loss) for the period by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income (loss) for the period by the weighted average number of common shares outstanding during the period, plus the dilutive effect of outstanding restricted stock units and awards, performance stock units, stock options, and shares issuable under the employee stock purchase plan as applicable pursuant to the treasury stock method. The anti-dilutive stock options and shares of outstanding and unvested restricted stock were excluded from the computation of net loss per share for the three and six months ended March 31, 2020 due to the Company incurring a net loss for the period.

Employee Stock Purchase Plan

We maintain an Employee Stock Purchase Plan (“ESPP”) which provides employees an opportunity to purchase common stock through payroll deductions. The ESPP is a 6-month duration plan with new participation periods beginning on approximately February 25 and August 26 of each year. The purchase price is set at 85% of the average high and low market price of our common stock on either the first or last trading day of the participation period, whichever is lower, and annual contributions are limited to the lower of 10% of an employee’s compensation or $25,000.

Public Offering

On February 16, 2021, we closed our offering of 6,655,093 shares of our common stock, which included the full exercise of the underwriters’ option to purchase 868,056 additional shares of common stock, at a price to the public of $5.40 per share, resulting in net proceeds to us from the offering, after deducting the underwriting discounts and commissions and other offering expenses, of approximately $33.1 million. The shares were sold by us pursuant to an underwriting agreement with Cowen and Company, LLC, dated as of February 10, 2021.

Future Issuances

As of March 31, 2021, we had common stock reserved for the following future issuances:


Future Issuances			Number of Common Stock Shares Available for Future Issuances

NOTE 13. Segment Data and Related Information

The reportable segments reported below are the Company’s segments for which separate financial information is available and upon which operating results are evaluated by the chief operating decision maker to assess performance and to allocate resources. The Company has determined that it has two reportable segments: (i) Aerospace and Defense and (ii) Broadband.

The Company’s Chief Executive Officer is the chief operating decision maker and he assesses the performance of the operating segments and allocates resources based on segment profits. We do not allocate sales and marketing, general and administrative expenses, or interest expense and interest income to our segments, because management does not include the information in its measurement of the performance of the operating segments. Also, a measure of segment assets and liabilities, has not been provided to the Company's chief operating decision maker and therefore is not shown below.

Table of Contents

The Aerospace and Defense segment is comprised of two product lines: (a) Navigation and Inertial Sensing; and (b) Defense Optoelectronics. The Broadband segment is comprised of three product lines: (a) CATV Lasers and Transmitters; (b) Chip Devices; and (c) Other.

Business Overview

EMCORE pioneered the linear fiber optic transmission technology that enabled the world’s first delivery of CATV directly on fiber, and today is a leading provider of advanced Mixed-Signal Optics products serving the broadband communications and Aerospace and Defense markets. The Mixed-Signal Optics technology at the heart of our broadband communications products is shared with our fiber optic gyros and inertial sensors to provide the aerospace and defense markets with state-of-the-art navigations systems technology. With the acquisition of Systron Donner Inertial, Inc. (“SDI”), a navigation systems provider with a scalable, chip-based platform for higher volume gyro applications utilizing Quartz MEMS technology, in June 2019, EMCORE further expanded its portfolio of gyros and inertial sensors with SDI’s quartz MEMS gyro and accelerometer technology.

EMCORE has fully vertically-integrated manufacturing capability through our indium phosphide compound semiconductor wafer fabrication facility at our headquarters in Alhambra, CA, and through our quartz processing and sensor manufacturing facility in Concord, CA. These facilities support EMCORE’s vertically-integrated manufacturing strategy for quartz and fiber optic gyro products, for navigation systems, and for our chip, laser, transmitter, and receiver products for broadband applications.

We have two reporting segments: (a) Aerospace and Defense and (b) Broadband. Aerospace and Defense is comprised of two product lines: (i) Navigation and Inertial Sensing; and (ii) Defense Optoelectronics. The Broadband segment is comprised of three product lines: (i) CATV Lasers and Transmitters; (ii) Chip Devices; and (iii) Other.

Recent Developments

COVID-19

The ongoing COVID-19 pandemic has negatively affected the U.S. and global economy, disrupted global supply chains, significantly restricted travel and transportation, resulted in mandated closures and orders to “shelter-in-place,” and created significant disruption of the financial markets. The full extent of the COVID-19 impact on our operational and financial performance will depend on future developments, including the duration and spread of the pandemic, the emergence of new strains of the virus, the impact of vaccination efforts, and related actions taken by the U.S. government, state and local government officials, and international governments to prevent disease spread, all of which are uncertain, out of our control, and cannot be predicted.

Each region we and our supply chain partners operate in has been affected by COVID-19 at varying times and magnitudes, often creating unforeseen challenges associated with logistics, raw material supply and labor shortages. In accordance with applicable U.S. state and county ordinances generally exempting essential businesses and/or critical infrastructure workforces from mandated closures and orders to “shelter-in-place,” our U.S. production facilities have continued to operate in support of essential products and services, subject to limitations and requirements pursuant to applicable state and county orders with regard to ongoing operations that have reduced the efficiency of our engineering and operational teams.

We rely on third party suppliers and contract manufacturers to provide materials, major components and products, and services. Many of our suppliers have at times temporarily ceased or limited operations as a result of COVID-19 and failed to deliver parts or components to us. For example, in the quarter ended March 31, 2021, COVID-19 driven component shortages required us to spend significant time sourcing critical components from alternative sources and, in some cases, forced us to design in alternative parts and qualify them with customers on short schedules. In addition, we continue to closely monitor the level of

Table of Contents

COVID-19 transmission in Thailand, and any effects this may have on production levels of our CATV module and transmitter products by our contract manufacturer located there.

We remain diligent in continuing to identify and manage risks to our business given the changing uncertainties related to COVID-19 and have plans in place intended to address or mitigate shortages of labor, material supplies and logistics services. While we believe that our supply chain, logistics and operations teams are currently in a position to meet expected customer demand levels in the coming quarters, we recognize that unpredictable events could create new challenges in the months ahead. We may not be able to address these challenges in a timely manner, which could negatively impact our financial results.

In addition, restrictions related to the COVID-19 pandemic have negatively affected the timing of the sale and transfer of certain CATV module and transmitter manufacturing equipment to the Buyers (defined below), as described in more detail below under “Hytera Transactions”. While the Thai government has started to loosen entry restrictions for foreign workers slightly, travel into Thailand by our manufacturing engineers to support the transfer may remain difficult. While we are taking actions within our supply chain and manufacturing operations to mitigate the effects of these delays, the timing and completion of these transfers may be further disrupted as a result of COVID-19, which could delay our recognition of the anticipated benefits of transferring this equipment and could disrupt our manufacturing activities for these products.

Our customer orders to date have generally remained stable with our pre-COVID-19 outlook, except with respect to customer orders related to the CATV Lasers and Transmitters product line, which have increased compared to our pre-COVID-19 outlook. However, qualification testing for certain of our products has continued to be delayed due to customer engineering shortages and limitations on their ability to access their facilities, and development timelines for certain programs continue to be extended. We continue to analyze on an ongoing basis how COVID-19 related actions could affect our product development efforts, future customer demand, timing of orders, recognized revenues, and cash flows.

Equity Offering

Hytera Transactions

As part of the effort to streamline operations and move to a variable cost model in our CATV Lasers and Transmitters product line, on October 25, 2019, we entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Hytera Communications (Hong Kong) Company Limited, a limited liability company incorporated in Hong Kong (“Hytera HK”), and Shenzhen Hytera Communications Co., Ltd., a corporation formed under the laws of the P.R.C. (“Shenzhen Hytera”, and together with Hytera HK, the “Buyers”), pursuant to which the Buyers agreed to purchase from EMCORE certain CATV module and transmitter manufacturing equipment (the “Equipment”) owned by EMCORE and currently located at the manufacturing facility of EMCORE’s wholly-owned subsidiary, EMCORE Optoelectronics (Beijing) Co, Ltd., a corporation formed under the laws of the P.R.C., for an aggregate purchase price of approximately $5.54 million.

The Equipment is in the process of being transferred to the Buyers in multiple closings, some of which have been delayed due to travel restrictions and the customer product qualification process during the COVID-19 pandemic, the last of which is now expected to occur during the quarter ending December 31, 2021. Concurrently, with our entry into the Asset Purchase Agreement, we entered into a Contract Manufacturing Agreement (the “Manufacturing Agreement”) on October 25, 2019, pursuant to which the Buyers agreed to manufacture certain CATV module and transmitter products for us from a manufacturing facility located in Thailand for an initial five year term at product prices agreed to between the parties. The manufacture, purchase and sale of certain CATV module and transmitter products from the Thailand manufacturing facility pursuant to the Manufacturing Agreement, has commenced and is ongoing.

Total revenue	$	38,406	$	23,850	$	14,556	61.0	%

Aerospace and Defense Revenue:

For the three months ended March 31, 2021, our Aerospace and Defense revenue increased $121,000, or 0.9%, compared to the same period in the prior year primarily driven by a $151,000 increase in our Navigation and Inertial Sensing product line revenue driven by an increase in customer demand.

Broadband Revenue:

For the three months ended March 31, 2021, our Broadband revenue increased $14.4 million, or 133.2%, compared to the same period in the prior year primarily driven by a $12.3 million increase in our CATV Lasers and Transmitters product line and a $2.1 million increase in our Other product line driven by increased customer demand. Increased customer demand arose in part from an increase in investment by cable TV multiple-system operators (“MSOs”) in their networks to address the bottlenecks created by bandwidth demands from both work-from-home initiatives and “stay at home” entertainment.

Table of Contents

Our cost of revenue consists of raw materials, compensation expense including non-cash stock-based compensation expense, depreciation expense and other manufacturing overhead costs, expenses associated with excess and obsolete inventories, and product warranty costs. Historically, our cost of revenue as a percentage of revenue, which we refer to as our gross margin, has fluctuated significantly due to product mix, manufacturing yields, sales volumes, inventory and specific product warranty charges, as well as the amount of our revenue relative to fixed manufacturing costs.

Consolidated gross margins were 38.1% and 26.9% for the three months ended March 31, 2021 and 2020, respectively.

Stock-based compensation expense within cost of revenue totaled approximately $0.2 million for each of the three months ended March 31, 2021 and 2020.

Aerospace and Defense Gross Profit:

For the three months ended March 31, 2021, Aerospace and Defense gross profit increased $0.9 million, or 32.7%, compared to the same period in the prior year, primarily driven by favorable product mix. For the three months ended March 31, 2021 and 2020, Aerospace and Defense gross margin was 28.7% and 21.9%, respectively. The increase in gross margin in the three months ended March 31, 2021 is driven by favorable product mix and lower overall manufacturing spending.

Broadband Gross Profit:

For the three months ended March 31, 2021, Broadband gross profit increased $7.3 million, or 203.1%, compared to the same period in the prior year, primarily as a result of higher revenue of $14.4 million offset by an increase in higher cost of revenue of $7.2 million. For the three months ended March 31, 2021 and 2020, Broadband gross margin was 43.0% and 33.1%, respectively. The increase in gross margin in the three months ended March 31, 2021 is primarily driven by an increase in revenue relative to fixed manufacturing costs and product mix.

Selling, General and Administrative (“SG&A”)

SG&A consists primarily of compensation expense including non-cash stock-based compensation expense related to executive, finance, and human resources personnel, as well as sales and marketing expenses, professional fees, legal and patent-related costs, and other corporate-related expenses.

Stock-based compensation expense within SG&A totaled approximately $0.5 million and $0.6 million for the three months ended March 31, 2021 and 2020, respectively.

SG&A expense for the three months ended March 31, 2021 was $1.1 million lower than the amount reported in the same period in the prior year primarily due to lower compensation and travel related expenses.

As a percentage of revenue, SG&A expenses were 15.8% and 29.9% for the three months ended March 31, 2021 and 2020, respectively.

Research and Development (“R&D”)

R&D consists primarily of compensation expense including non-cash stock-based compensation expense, as well as engineering and prototype costs, depreciation expense, and other overhead expenses, as they relate to the design, development, and testing of our products. Our R&D costs are expensed as incurred. We believe that in order to remain competitive, we must invest significant financial resources in developing new product features and enhancements and in maintaining customer satisfaction worldwide.

Stock-based compensation expense within R&D totaled approximately $0.2 million during each of the three months ended March 31, 2021 and 2020.

For the three months ended March 31, 2021 and 2020, Aerospace and Defense R&D expense was $3.2 million and $4.0 million, respectively. For the each of the three months ended March 31, 2021 and 2020, Broadband R&D expense was $0.6 million.

R&D expense for the three months ended March 31, 2021 was lower than the amounts reported in the same period in the prior year by $0.8 million primarily due to lower compensation and project related expense.

Table of Contents

As a percentage of revenue, R&D expenses were 9.8% and 19.2% for the three months ended March 31, 2021 and 2020, respectively.

Operating Income (Loss)

Operating income (loss) represents revenue less the cost of revenue and operating expenses incurred. Operating income (loss) is a measure that executive management uses to assess performance and make decisions.

As a percentage of revenue, our operating income (loss) was 11.9% and (20.9)% for the three months ended March 31, 2021 and 2020, respectively.

The improvement of $9.6 million in operating income (loss) in the three months ended March 31, 2021 compared to the same period in the prior year is driven by an increase in revenue of $14.6 million and an increase in gross profit of $8.2 million, while research and development expense decreased by $0.8 million, and selling, general and administrative expense decreased by $1.1 million, offset by a decrease in gain on sale of equipment of $0.5 million.

Other Income

Interest (Expense) Income, net

During the three months ended March 31, 2021 and 2020, we recorded $(49,000) of interest expense, net and $1,000 of interest income, net, respectively. Interest expense is related to our Credit Facility (as defined below) and PPP Loan, and interest income is earned on cash and cash equivalent balances.

Foreign Exchange (Loss) Gain

Gains or losses from foreign currency transactions denominated in currencies other than the U.S. dollar, both realized and unrealized, are recorded as foreign exchange (loss) gain on our Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). The (losses) gains recorded relate to the change in value of the Chinese Yuan Renminbi relative to the U.S. dollar.

Income Tax (Expense) Benefit

During the three months ended March 31, 2021 and 2020, the Company recorded income tax (expense) benefit of approximately $(82,000) and $55,000, respectively. Income tax expense for each of the three months ended March 31, 2021 and 2020 is composed primarily of state tax expense. The increase in income tax expense is driven by the State of California's temporary suspension of NOL utilization.

Order Backlog

EMCORE’s product sales are made pursuant to purchase orders, often with short lead times. These orders are subject to revision or cancellation and often are made without deposits. In addition, in some recent periods, Broadband products have typically shipped within the same quarter in which a purchase order is received. Therefore, our order backlog at any particular date is not necessarily indicative of actual revenue or the level of orders for any succeeding period and may not be comparable to prior periods. We have experienced an increase in our backlog in our CATV Lasers and Transmitters product line through the quarter ending March 31, 2022 driven by increased customer demand, arising in part from an increase in investment by MSOs in their networks to break the bottlenecks created by bandwidth demands from both work-from-home initiatives and “stay at home” entertainment as a result of the COVID-19 pandemic. However, these orders in our CATV Lasers and

Table of Contents

Transmitters product line are subject to revision or cancellation and we can provide no assurance that such an increase in our backlog will result in corresponding revenue.

Liquidity and Capital Resources

We have historically consumed cash from operations and, in most periods, we have incurred operating losses from continuing operations. We have managed our liquidity position through the sale of assets, cost reduction initiatives, and capital market transactions as well as, from time to time in prior periods, borrowings from our Credit Facility (defined below).

As of March 31, 2021, cash and cash equivalents totaled $65.3 million and net working capital totaled approximately $103.2 million. Net working capital, calculated as current assets (including inventory) minus current liabilities, is a financial metric we use which represents available operating liquidity.

On November 11, 2010, we entered into a Credit and Security Agreement (as amended to date, the “Credit Facility”) with Wells Fargo Bank, N.A. (“Wells Fargo”). The Credit Facility currently provides us with a revolving credit line of up to $15.0 million that can be used for working capital requirements, letters of credit, acquisitions, and other general corporate purposes subject to requirements that (a) we have (i) liquidity of at least $10.0 million, and (ii) for certain specific uses, liquidity of at least $25.0 million after such use and (b) we maintain excess availability of at least $1.0 million. The Credit Facility has a maturity date expiring in November 2021, is secured by our assets and is subject to a borrowing base formula based on the Company’s eligible accounts receivable, inventory, and machinery and equipment accounts. See "Note 9 - Credit Facilities and Debt" in the notes to the condensed consolidated financial statements for additional disclosures. As of April 30, 2021, there was no outstanding balance under this Credit Facility, $0.5 million reserved for one outstanding stand-by letter of credit and $13.4 million available for borrowing.

On May 3, 2020, we entered into a Paycheck Protection Program Promissory Note and Agreement (the “PPP Loan Agreement”) with Wells Fargo Bank, N.A. under the Paycheck Protection Program (“PPP”) established under the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) to receive loan proceeds of approximately $6.5 million (the “PPP Loan”), which we received on May 6, 2020.

The PPP Loan matures on May 3, 2022 and bears interest at a fixed rate of 1.00% per annum, payable monthly. Monthly payments in the amount of $273,160 will be due and payable beginning at such time as is in accordance with the terms of the Paycheck Protection Flexibility Act of 2020 and continuing each month thereafter until maturity of the PPP Loan. There is no prepayment penalty. Under the terms of the PPP, all or a portion of the principal may be forgiven if the PPP Loan proceeds are used for qualifying expenses as described in the CARES Act, such as payroll costs, benefits, rent, and utilities. During the three months ended March 31, 2021 we applied for forgiveness of the PPP Loan. We can provide no assurance that we will obtain forgiveness of the PPP Loan in whole or in part. With respect to any portion of the PPP Loan that is not forgiven, the PPP Loan will be subject to customary provisions for a loan of this type, including customary events of default relating to, among other things, payment defaults and breaches of the provisions of the PPP Loan Agreement.

We have a history of operating losses and negative cash flows from operations. We believe that our existing balances of cash and cash equivalents, cash flows from operations and amounts expected to be available under our Credit Facility and any amounts that may be available to us under governmental lending programs will provide us with sufficient financial resources to meet our cash requirements for operations, working capital, and capital expenditures for at least the next twelve months from the date of the issuance of these financial statements. We have taken a number of actions to continue to support our operations and meet our obligations, including the February 2021 offering of shares of our common stock described in more detail above, completing the sale of the Concord Real Property, headcount reductions and other cost reductions and obtaining the PPP Loan. In addition, should we require more capital than what is generated by our operations, we could engage in additional sales or other monetization of certain fixed assets, additional cost reductions, or elect to raise capital in the U.S. through debt or additional equity issuances. These alternatives may not be available to us on reasonable terms or at all, and could result in higher effective tax rates, increased interest expense, and/or dilution of our earnings.

As described above, the continued spread of COVID-19 has led to disruption and volatility in the global capital markets, which, depending on future developments, could impact our capital resources in the future. If we need to raise additional capital to

support operations in the future, we may be unable to access capital markets and additional capital may only be available to us on terms that could be significantly detrimental to our existing shareholders and to our business.

The change in our operating assets and liabilities was driven by an increase in accounts receivable of $2.4 million and other assets of $13.8 million and a decrease in accounts payable of $0.5 million and accrued expenses and other liabilities of $10.7 million, partially offset by a decrease in inventory of $0.5 million.

Working Capital Components:

Accounts Receivable: We generally expect the level of accounts receivable at any given quarter end to reflect the level of sales in that quarter. Our accounts receivable balances have historically fluctuated due to the timing of account collections, timing of product shipments, and/or change in customer credit terms.

Inventory: We generally expect the level of inventory at any given quarter end to reflect the change in our expectations of forecasted sales during the quarter. Our inventory balances have historically fluctuated due to the timing of customer orders and product shipments, changes in our internal forecasts related to customer demand, as well as adjustments related to excess and obsolete inventory and the purchase of non-current inventory.

Accounts Payable: The fluctuation of our accounts payable balances is primarily driven by changes in inventory purchases as well as changes related to the timing of actual payments to vendors.

Accrued Expenses: Our largest accrued expense typically relates to compensation. Historically, fluctuations of our accrued expense accounts have primarily related to changes in the timing of actual compensation payments, receipt or application of advanced payments, adjustments to our warranty accrual, and accruals related to professional fees.

Critical Accounting Policies and Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, as of the date of the financial statements, and the reported amounts of revenue and expenses during the reported period. If these estimates differ significantly from actual results, the impact to the condensed consolidated financial statements may be material. There have been no material changes in our critical accounting policies and estimates from those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. Please refer to Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020 for a discussion of our critical accounting policies and estimates.

ITEM 4. Controls and Procedures

a.Evaluation of Disclosure Controls and Procedures

Our management, with the participation of its Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer and Accounting Officer), evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of March 31, 2021.

PART II. Other Information.

ITEM 1. Legal Proceedings

See the disclosures under the caption “Legal Proceedings” in "Note 11 - Commitments and Contingencies" in the notes to our condensed consolidated financial statements for disclosures related to our legal proceedings, which disclosures are incorporated herein by reference.

ITEM 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the risk factors discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10‑K for the fiscal year ended September 30, 2020, which could materially affect our business, financial condition or future results. Except for the risk factor discussed below, we do not believe that there have been any material changes to the risk factors disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. The risks described in our Annual Report on Form 10‑K and described below are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem immaterial also may materially adversely affect our business, financial condition, operating results and/or cash flows.

The full effects of COVID-19 and other potential future public health crises, epidemics, pandemics or similar events are uncertain and could have a material and adverse effect on our business, financial condition, operating results and cash flows.

The ongoing COVID-19 pandemic has negatively affected the U.S. and global economy, disrupted global supply chains, significantly restricted travel and transportation, resulted in mandated closures and orders to “shelter-in-place,” and created significant disruption of the financial markets. The full extent of the COVID-19 impact on our operational and financial performance will depend on future developments, including the duration and spread of the pandemic, the emergence of new strains of the virus, the impact of vaccination efforts and related actions taken by the U.S. government, state and local government officials, and international governments to prevent disease spread, all of which are uncertain, out of our control and cannot be predicted.

In accordance with applicable U.S. state and county ordinances generally exempting essential businesses and/or critical infrastructure workforces from mandated closures and orders to “shelter-in-place,” our U.S. production facilities have continued to operate in support of essential products and services, subject to limitations and requirements pursuant to applicable state and county orders with regard to ongoing operations that have reduced the efficiency of our engineering and operational teams. However, facility closures or further work slowdowns or temporary stoppages could occur, and in some cases, our facilities and supplier facilities are not operating under full staffing as a result of COVID-19, which could have a longer-term impact and could delay our development efforts and our deliveries to customers. In addition, other countries have different practices and policies that can affect our international operations and the operations of our suppliers and customers. For example, operations

Table of Contents

at our Beijing facility ceased for one additional week beyond the Chinese New Year holiday in February 2020 as a result of the COVID-19 situation, and additional closures could occur.

In addition, the COVID-19 pandemic has negatively affected, and could have further negative effects on, the timing of the sale and transfer of certain CATV module and transmitter manufacturing equipment that we have agreed, as part of our efforts to streamline operations and move to a variable cost model in our CATV Lasers and Transmitters product line, to sell to Hytera Communications (Hong Kong) Company Limited (“Hytera HK”), and Shenzhen Hytera Communications Co., Ltd. (“Shenzhen Hytera”, and together with Hytera HK, the “Buyers”), for use by the Buyers in connection with the manufacturing of certain CATV module and transmitter products for us from a manufacturing facility located in Thailand. The sale and transfer of the equipment will occur in three separate closings, one of which occurred in the quarter ended December 31, 2019 and the other two of which are now expected to occur during the quarter ending December 31, 2021. The timing and completion of these transfers may be further disrupted as a result of COVID-19, which could delay our recognition of the anticipated benefits of transferring this equipment and could disrupt our manufacturing activities for these products.

If significant portions of our workforce are unable to work effectively, including because of illness, quarantines, absenteeism, government actions, facility closures, travel restrictions or other restrictions in connection with the COVID-19 pandemic, our operations will be negatively impacted. We may be unable to perform fully on our contracts and our costs may increase as a result of the COVID-19 outbreak. The impact of COVID-19 could worsen if there is an extended duration of any COVID-19 outbreak or a resurgence of COVID-19 infection in affected regions after they have begun to experience improvement.

We rely on other companies to provide materials, major components and products, and to perform a portion of the services that are provided to our customers under the terms of most of our contracts where we rely on these third parties. Many of our suppliers have at times temporarily ceased or limited operations as a result of COVID-19 and failed to deliver parts or components to us. For example, in the quarter ended March 31, 2021, COVID-19 driven component shortages required us to spend significant time sourcing critical components from alternative sources and, in some cases, forced us to design in alternative parts and qualify them with customers on short schedules. These or similar actions may continue in the future, and an extended period of global supply chain disruption caused by the response to COVID-19 could impact our ability to perform on our contracts and, if we are not able to implement alternatives or other mitigations, product deliveries could be adversely impacted.

As a result of COVID-19, we could see reduced customer orders in certain of our product lines, which could adversely affect our revenues, financial performance and cash flows, and could result in inventory write-downs and impairment losses. Significant delays in inspection, acceptance and payment by our customers, many of whom are teleworking, could also affect our revenues and cash flows, and current limitations on travel to customers could impact orders. For example, qualification testing for certain of our products continues to be delayed due to customer engineering shortages and limitations on their ability to access their facilities. In addition, limitations on government operations can also impact regulatory approvals such as export licenses that are needed for international sales and deliveries for certain of our products. Government funding priorities may change as a result of the costs of COVID-19, which could adversely affect our revenues arising from government contracts or subcontracts, and with respect to such contracts, we could experience delays in new program starts or awards of future work or in timelines for current programs, as well as the uncertain impact of contract modifications to respond to the national emergency.

The continued spread of COVID-19 has also led to disruption and volatility in the global capital markets, which, depending on future developments, could impact our capital resources and liquidity in the future. If we need to raise additional capital to support operations in the future, we may be unable to access capital markets and additional capital may only be available to us on terms that could be significantly detrimental to our existing shareholders and to our business as a result of COVID-19. We are also monitoring the impacts of COVID-19 on the fair value of our assets. While we do not currently anticipate any material impairments on our assets as a result of COVID-19, future changes in expectations for sales, earnings and cash flows related to intangible assets and below our current projections could cause these assets to be impaired.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements (a)New Accounting Updates Recently Adopted •In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the way entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net earnings. The new standard is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. The new standard was effective for our fiscal year beginning October 1, 2020. We adopted the new standard on October 1, 2020, and it did not have a material impact on the condensed consolidated financial statements. (b)Recent Accounting Standards or Updates Not Yet Effective •In March 2020, the FASB issued ASU 2019-12 Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The new standard is effective for annual periods beginning after December 15, 2020, including interim periods within those annual periods. The new standard will be effective for our fiscal year beginning October 1, 2021 and early adoption is permitted. The Company is currently evaluating the new guidance to determine the impact it may have on the condensed consolidated financial statements and related disclosures.

Fair Value Accounting	6 Months Ended
Fair Value Accounting	Mar. 31, 2021
Fair Value Disclosures [Abstract]
Fair Value Accounting	Fair Value Accounting Accounting Standards Codification Topic 820 (“ASC 820”), Fair Value Measurement, establishes a valuation hierarchy for disclosure of the inputs to valuation techniques used to measure fair value. This standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: •Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. •Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly, through market corroboration, for substantially the full term of the financial instrument. •Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets or liabilities at fair value. Classification of an asset or liability within this hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. Cash consists primarily of bank deposits or highly liquid short-term investments with a maturity of three months or less at the time of purchase. Restricted cash represents temporarily restricted deposits held as compensating balances against short-term borrowing arrangements. Cash, cash equivalents and restricted cash are based on Level 1 measurements. The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, contract assets, other current assets, and accounts payable approximate fair value because of the short maturity of these instruments.

Credit Facilities and Debt	6 Months Ended
Credit Facilities and Debt	Mar. 31, 2021
Debt Disclosure [Abstract]
Credit Facilities and Debt	Credit Facilities and Debt Credit Facilities On November 11, 2010, we entered into a Credit and Security Agreement (as amended to date, the “Credit Facility”) with Wells Fargo Bank, N.A. The Credit Facility is secured by the Company’s assets and is subject to a borrowing base formula based on the Company’s eligible accounts receivable, inventory, and machinery and equipment accounts. The Credit Facility matures in November 2021 and currently provides us with a revolving credit line of up to $15.0 million, subject to a borrowing base formula, that can be used for working capital requirements, letters of credit, acquisitions, and other general corporate purposes subject to a requirement, for certain specific uses, that the Company has liquidity of at least $25.0 million after such use. The Credit Facility requires us to maintain (a) liquidity of at least $10.0 million and (b) excess availability of at least $1.0 million. As of March 31, 2021, there was no amount outstanding under this Credit Facility and the Company was in compliance with all financial covenants. Also, as of March 31, 2021, the Credit Facility had approximately $0.5 million reserved for one outstanding stand-by letter of credit and $13.4 million available for borrowing. Debt On May 3, 2020, the Company entered into a Paycheck Protection Program Promissory Note and Agreement (the “PPP Loan Agreement”) with Wells Fargo Bank, N.A. under the Paycheck Protection Program (“PPP”) established under the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) to receive loan proceeds of approximately $6.5 million (the “PPP Loan”), which the Company received on May 6, 2020. The PPP Loan matures on May 3, 2022 and bears interest at a fixed rate of 1.00% per annum, payable monthly. Monthly payments in the amount of $273,160 will be due and payable beginning at such time as is in accordance with the terms of the Paycheck Protection Flexibility Act of 2020 and continuing each month thereafter until maturity of the PPP Loan. There is no prepayment penalty. Under the terms of the PPP, all or a portion of the principal may be forgiven if the PPP Loan proceeds are used for qualifying expenses as described in the CARES Act, such as payroll costs, benefits, rent, and utilities. With respect to any portion of the PPP Loan that is not forgiven, the PPP Loan will be subject to customary provisions for a loan of this type, including customary events of default relating to, among other things, payment defaults and breaches of the provisions of the PPP Loan Agreement. The Company applied for forgiveness of the PPP Loan during the three months ended March 31, 2021, but it can make no assurance that forgiveness will be granted in part or in whole. As of March 31, 2021, $1.9 million is recorded in current liabilities and $4.6 million is recorded in long-term liabilities on the Company’s condensed consolidated balance sheet.

Income and Other Taxes	6 Months Ended
Income and Other Taxes	Mar. 31, 2021
Income Tax Disclosure [Abstract]
Income and Other Taxes	Income and Other Taxes During the three months ended March 31, 2021 and 2020, the Company recorded income tax (expense) benefit of approximately $(82,000) and $55,000, respectively. Income tax expense for the three months ended March 31, 2021 and 2020 is composed primarily of state tax expense. The increase in income tax expense is driven by the State of California's temporary suspension of net operating loss ("NOL") utilization. During the six months ended March 31, 2021 and 2020, the Company recorded income tax (expense) benefit of approximately $(208,000) and $41,000, respectively. Income tax expense for the six months ended March 31, 2021 and 2020 is composed primarily of state tax expense. The increase in income tax expense is driven by the State of California’s temporary suspension of NOL utilization. For the three months ended March 31, 2021 and 2020 the effective tax rate on continuing operations was 1.9% and 0.2%, respectively. The higher tax rate for the three months ended March 31, 2021 is primarily driven by the State of California's temporary suspension of NOL utilization. For the six months ended March 31, 2021 and 2020, the effective tax rate on continuing operations was 2.9% and 0.1%, respectively. The increased tax rate for the six months ended March 31, 2021 is primarily driven by the State of California’s temporary suspension of NOL utilization. The Company uses estimates to forecast the results from continuing operations for the current fiscal year as well as permanent differences between book and tax accounting. We have not provided for income taxes on non-U.S. subsidiaries’ undistributed earnings as of March 31, 2021 because we plan to indefinitely reinvest the unremitted earnings of our non-U.S. subsidiaries and all of our non-U.S. subsidiaries historically have negative earnings and profits. All deferred tax assets have a full valuation allowance at March 31, 2021. On a quarterly basis, the Company evaluates the positive and negative evidence to assess whether the more likely than not criteria has been satisfied in determining whether there will be further adjustments to the valuation allowance. During the three and six months ended March 31, 2021 and 2020, there were no material increases or decreases in unrecognized tax benefits. As of March 31, 2021 and September 30, 2020, we had approximately $0.6 million of interest and penalties and $0.4 million of uncertain tax benefit reserved and accrued for as tax liabilities on our balance sheet. We expect that $1.0 million of uncertain tax benefit including interest and penalties will be settled within the next 12 months, which will impact the effective tax rate. Interest that is accrued on tax liabilities is recorded within interest expense on the condensed consolidated statements of operations.

Commitments and Contingencies	Mar. 31, 2021
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Indemnifications: We have agreed to indemnify certain customers against claims of infringement of intellectual property rights of others in our sales contracts with these customers. Historically, we have not paid any claims under these customer indemnification obligations. We enter into indemnification agreements with each of our directors and executive officers pursuant to which we agree to indemnify them for certain potential expenses and liabilities arising from their status as a director or executive officer of the Company. We maintain directors and officers insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and executive officers in certain circumstances. It is not possible to determine the aggregate maximum potential loss under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular claim. Legal Proceedings: We are subject to various legal proceedings, claims, and litigation, either asserted or unasserted, that arise in the ordinary course of business. The outcome of these matters is currently not determinable and we are unable to estimate a range of loss, should a loss occur, from these proceedings. The ultimate outcome of legal proceedings involves judgments, estimates and inherent uncertainties and the results of these matters cannot be predicted with certainty. Professional legal fees are expensed when incurred. We accrue for contingent losses when such losses are probable and reasonably estimable. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information. Should we fail to prevail in any legal matter or should several legal matters be resolved against the Company in the same reporting period, then the financial results of that particular reporting period could be materially affected. a) Intellectual Property Lawsuits We protect our proprietary technology by applying for patents where appropriate and, in other cases, by preserving the technology, related know-how and information as trade secrets. The success and competitive position of our product lines are impacted by our ability to obtain intellectual property protection for our research and development efforts. We have, from time to time, exchanged correspondence with third parties regarding the assertion of patent or other intellectual property rights in connection with certain of our products and processes. b) Resilience Litigation In February 2021, Resilience Capital (“Resilience”) filed a complaint against us with the Delaware Chancery Court containing claims arising from the February 2020 sale of SDI’s real property (the “Concord Property Sale”) located in Concord, California (the “Concord Real Property”) to Eagle Rock Holdings, LP (“Buyer”) and that certain Single-Tenant Triple Net Lease, dated as of February 10, 2020, entered into by and between SDI and the Buyer, pursuant to which SDI leased from the Buyer the Concord Real Property for a 15 year term. The Resilience complaint seeks, among other items, (i) a declaration that the Concord Property Sale included a non-cash component; (ii) a decree requiring us and Resilience to follow the appraisal requirements set forth in that certain Purchase and Sale Agreement (the "SDI Purchase Agreement"), dated as of June 7, 2019, by and among EMCORE Corporation, The Resilience Fund IV, L.P., The Resilience Fund IV-A, L.P., Aerospace Newco Holdings, Inc. and Ember Acquisition Sub, Inc.; (iii) recovery of Resilience’s costs and expenses; and (iv) pre- and post-judgment interest. In April 2021, we filed with the Delaware Chancery Court our answer to the Resilience complaint and counterclaims against Resilience, in which we are seeking, among other items, (i) dismissal of the Resilience complaint and/or granting of judgment in favor of EMCORE with respect to the Resilience complaint, (ii) entering final judgment against Resilience awarding damages to us for Resilience’s fraud and breaches of the SDI Purchase Agreement in an amount to be proven at trial and not less than $1,565,000, (iii) a judicial determination of the respective rights and duties of us and Resilience under the SDI Purchase Agreement, (iv) an award to us of costs and expenses and (v) pre- and post-judgment interest. We believe that the claims made by Resilience in its complaint are without merit and we intend to vigorously defend ourselves against them.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Financial Statements	Interim Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim information, and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by U.S. GAAP for annual financial statements. In our opinion, the interim financial statements reflect all adjustments, which are all normal recurring adjustments, that are necessary to provide a fair presentation of the financial results for the interim periods presented. Operating results for interim periods are not necessarily indicative of results that may be expected for an entire fiscal year. The condensed consolidated balance sheet as of September 30, 2020 has been derived from the audited consolidated financial statements as of such date. For a more complete understanding of our business, financial position, operating results, cash flows, risk factors and other matters, please refer to our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.
Significant Accounting Policies and Estimates	Significant Accounting Policies and Estimates Our significant accounting policies are detailed in “Note 2 - Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the year ended September 30, 2020. There have been no significant changes to our accounting policies during the six months ended March 31, 2021. The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, as of the date of the financial statements, and the reported amounts of revenue and expenses during the reported period. If these estimates differ significantly from actual results, the impact to the condensed consolidated financial statements may be material. There have been no material changes in our critical accounting policies and estimates from those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020. Please refer to Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020 for a discussion of our critical accounting policies and estimates.
Disaggregation of Revenue and Revenue Recognition	Disaggregation of Revenue - Revenue is classified based on the product line of business. For additional information on the disaggregated revenues by geographical region, see "Note 13 – Segment Data and Related Information" in the notes to the condensed consolidated financial statements.
New Accounting Updates Recently Adopted and Recent Accounting Standards or Updates Not Yet Effective	New Accounting Updates Recently Adopted •In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the way entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net earnings. The new standard is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. The new standard was effective for our fiscal year beginning October 1, 2020. We adopted the new standard on October 1, 2020, and it did not have a material impact on the condensed consolidated financial statements. (b)Recent Accounting Standards or Updates Not Yet Effective •In March 2020, the FASB issued ASU 2019-12 Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The new standard is effective for annual periods beginning after December 15, 2020, including interim periods within those annual periods. The new standard will be effective for our fiscal year beginning October 1, 2021 and early adoption is permitted. The Company is currently evaluating the new guidance to determine the impact it may have on the condensed consolidated financial statements and related disclosures.
Fair Value of Financial Instruments	Accounting Standards Codification Topic 820 (“ASC 820”), Fair Value Measurement, establishes a valuation hierarchy for disclosure of the inputs to valuation techniques used to measure fair value. This standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: •Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. •Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly, through market corroboration, for substantially the full term of the financial instrument. •Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets or liabilities at fair value. Classification of an asset or liability within this hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs.
Cash and Cash Equivalents	Cash consists primarily of bank deposits or highly liquid short-term investments with a maturity of three months or less at the time of purchase.
Restricted Cash	Restricted cash represents temporarily restricted deposits held as compensating balances against short-term borrowing arrangements.
Legal Costs	Professional legal fees are expensed when incurred. We accrue for contingent losses when such losses are probable and reasonably estimable.
Segment Reporting	The reportable segments reported below are the Company’s segments for which separate financial information is available and upon which operating results are evaluated by the chief operating decision maker to assess performance and to allocate resources. The Company has determined that it has two reportable segments: (i) Aerospace and Defense and (ii) Broadband. The Company’s Chief Executive Officer is the chief operating decision maker and he assesses the performance of the operating segments and allocates resources based on segment profits. We do not allocate sales and marketing, general and administrative expenses, or interest expense and interest income to our segments, because management does not include the information in its measurement of the performance of the operating segments. Also, a measure of segment assets and liabilities, has not been provided to the Company's chief operating decision maker and therefore is not shown below.
