This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on current expectations and projections about future events and financial trends affecting the financial condition of our business. Such forward-looking statements include, in particular, projections about our future results included in our Exchange Act reports and statements about plans, strategies, business prospects, changes and trends in our business and the markets in which we operate. These forward-looking statements may be identified by the use of terms and phrases such as “anticipates,” “believes,” “can,” “could,” “estimates,” “expects,” “forecasts,” “intends,” “may,” “plans,” “projects,” “should,” “targets,” “will,” “would,” and similar expressions or variations of these terms and similar phrases. Additionally, statements concerning future matters such as our expected liquidity, development of new products, enhancements or technologies, sales levels, expense levels, expectations regarding the outcome of legal proceedings, and other statements regarding matters that are not historical are forward-looking statements. Management cautions that these forward-looking statements relate to future events or our future financial performance and are subject to business, economic, and other risks and uncertainties, both known and unknown, that may cause actual results, levels of activity, performance, or achievements of our business or the industries in which we operate to be materially different from those expressed or implied by any forward-looking statements. Factors that could cause or contribute to such differences in results and outcomes include without limitation the following:

•uncertainties regarding the effects of the COVID-19 pandemic and the impact of measures intended to reduce its spread on our business and operations, which is evolving and beyond our control;

•the effect of component shortages and any alternatives thereto;

•the rapidly evolving markets for our products and uncertainty regarding the development of these markets;

•our historical dependence on sales to a limited number of customers and fluctuations in the mix of products and customers in any period;

•delays and other difficulties in commercializing new products;

•the failure of new products: (a) to perform as expected without material defects, (b) to be manufactured at acceptable volumes, yields, and cost, (c) to be qualified and accepted by our customers, and (d) to successfully compete with products offered by our competitors;

•uncertainties concerning the availability and cost of commodity materials and specialized product components that we do not make internally;

•actions by competitors;

•risks and uncertainties related to applicable laws and regulations, including the impact of changes to applicable tax laws and tariff regulations;

•acquisition-related risks, including that (a) revenue and net operating results obtained from the Systron Donner Inertial, Inc. ("SDI") business or the L3Harris Space and Navigation ("S&N") business may not meet our expectations, (b) the costs and cash expenditures for integration of the S&N business operations may be higher than expected, (c) there could be losses and liabilities arising from the acquisition of SDI or S&N that we will not be able to recover from any source and (d) we may not realize sufficient scale in our Navigation and Inertial Sensing product line from the SDI acquisition and the S&N acquisition and will need to take additional steps, including making additional acquisitions, to achieve our growth objectives for this product line;

•risks related to our ability to obtain capital;

•risks related to the transition of certain of our manufacturing operations from our Beijing facility to a contract manufacturer’s facility;

•risks and uncertainties related to manufacturing and production capacity and expansion plans related thereto; and

•other risks and uncertainties discussed in Part I, Item 1A, Risk Factors in our Annual Report on Form 10-K for the fiscal year ended September 30, 2021, as such risk factors may be amended, supplemented or superseded from time to time by our subsequent periodic reports we file with the Securities and Exchange Commission (“SEC”).

These cautionary statements apply to all forward-looking statements wherever they appear in this Quarterly Report. Forward-looking statements are based on certain assumptions and analysis made in light of experience and perception of historical trends, current conditions, and expected future developments as well as other factors that we believe are appropriate under the circumstances. While these statements represent judgment on what the future may hold, and we believe these judgments are reasonable, these statements are not guarantees of any events or financial results.

EMCORE Corporation

Notes to Condensed Consolidated Financial Statements

NOTE 1. Description of Business

EMCORE Corporation (referred to herein, together with its subsidiaries, as the “Company,” “we,” “our,” or “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 ("CATV") industry. We pioneered the linear fiber optic transmission technology that enabled the world’s first delivery of CATV directly on fiber, and today are a leading provider of advanced products that enable communications systems and service providers to meet growing demand for increased bandwidth and connectivity. The technology at the heart of our broadband communications products is shared with our fiber optic gyroscope (“FOG”) 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 micro-electromechanical system ("QMEMS") technology, in June 2019, we further expanded our portfolio of gyros and inertial sensors with SDI’s QMEMS gyro and accelerometer technology. We have fully vertically-integrated manufacturing capability through our indium phosphide ("InP") 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 our vertically-integrated manufacturing strategy for quartz and FOG 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 us which is unique in the optics industry.

NOTE 2. Summary of Significant Accounting Policies

Basis of Presentation

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 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, 2021 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, 2021.

Significant Accounting Policies and Estimates

There have been no material changes in our significant accounting policies and estimates from those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 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.

Recent Accounting Pronouncements

We recently adopted the following accounting standards, which had the following impacts on our consolidated financial statements:

In December 2019, the FASB issued Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing various exceptions, such as the exception to the incremental approach for intra-period tax allocation when there is a loss from continuing operations and income or a gain from other items. The amendments in this update also simplify the accounting for income taxes related to income-based franchise taxes and require that an entity reflect enacted tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The new standard was effective for our fiscal year beginning

10

October 1, 2021. The adoption of this new standard did not have a material impact on the condensed consolidated financial statements.

Other accounting standards that have been issued or proposed by FASB and do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.

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 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. In February 2022, we entered into an extension wherein the Credit Facility is to mature in May 2022. The Credit Facility currently provides us with a revolving credit line of up to $15.0 million at an interest rate equal to LIBOR plus 1.75%, 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.

12

As of March 31, 2022, there was no amount outstanding under this Credit Facility and the Company was in compliance with all financial covenants. Also, as of March 31, 2022, the Credit Facility had $0.5 million reserved for one outstanding stand-by letter of credit and $6.1 million available for borrowing.

NOTE 9. Income and Other Taxes

During the three months ended March 31, 2022 and 2021, the Company recorded an income tax benefit of $117 thousand and income tax expense of $82 thousand, respectively. Income tax benefit during the three months ended March 31, 2022 is composed primarily of state minimum taxes. Income tax expense during the three months ended March 31, 2021 is composed primarily of state tax expense which is driven by the State of California's temporary suspension of net operating loss ("NOL") utilization.

During the six months ended March 31, 2022 and 2021, the Company recorded an income tax benefit of $2 thousand and income tax expense of $208 thousand. Income tax benefit for the six months ended March 31, 2022 is composed primarily of state minimum taxes. Income tax expense for the six months ended March 31, 2021 is composed primarily of state tax expense which is driven by the State of California's temporary suspension of NOL utilization.

For the three months ended March 31, 2022 and 2021 the effective tax rate on continuing operations was (5.0)% and 1.8%, respectively. For the six months ended March 31, 2022 and 2021 the effective tax rate on continuing operations was 1.1% and 2.9%, respectively. The tax rate for the three and six months ended March 31, 2022 is primarily driven by the state minimum taxes.

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, 2022 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 as of March 31, 2022. 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.

As of March 31, 2022 and September 30, 2021, we had no uncertain tax benefit reserved and no interest and penalties accrued as tax liabilities on our balance sheet. During the three and six months ended March 31, 2022 and 2021, there were no material increases or decreases in unrecognized tax benefits.

NOTE 10. 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 covers certain liabilities relating to 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.

13

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.

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.

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, (a) a declaration that the Concord Property Sale included a non-cash component; (b) 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 the Company, The Resilience Fund IV, L.P., The Resilience Fund IV-A, L.P., Aerospace Newco Holdings, Inc. and Ember Acquisition Sub, Inc.; (c) recovery of Resilience’s costs and expenses; and (d) 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, (a) dismissal of the Resilience complaint and/or granting of judgment in favor of EMCORE with respect to the Resilience complaint, (b) 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, (c) a judicial determination of the respective rights and duties of us and Resilience under the SDI Purchase Agreement, (d) an award to us of costs and expenses and (e) 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 11. 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

•the 2019 Equity Incentive Plan.

We issue new shares of common stock to satisfy awards granted under our Equity Plans. In March 2022, our shareholders approved the Amended and Restated EMCORE Corporation 2019 Equity Incentive Plan, which was adopted by the Company’s Board of Directors in December 2021, 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 1.9 million 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, 2022 and 2021, our matching contribution in cash was $0.3 million. During each of the six months ended March 31, 2022 and 2021, our matching contribution in cash was $0.6 million.

Income Per Share

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

Weighted average antidilutive options, unvested restricted RSUs and RSAs, unvested PSUs and ESPP shares excluded from the computation	75		1,536		72		1,331

Basic earnings per share ("EPS") is computed by dividing net (loss) income for the period by the weighted-average number of common stock outstanding during the period. Diluted EPS is computed by dividing net (loss) income for the period by the weighted average number of common stock outstanding during the period, plus the dilutive effect of outstanding restricted stock units ("RSUs") and restricted stock awards ("RSAs"), performance stock units ("PSUs"), stock options, and shares issuable under the employee stock purchase plan ("ESPP") as applicable pursuant to the treasury stock method. Certain of the

15

Company's outstanding share-based awards, noted in the table above, were excluded because they were anti-dilutive, but they could become dilutive in the future.

Future Issuances

As of March 31, 2022, we had common stock reserved for the following future issuances:

	Number of Common Stock Shares Available for Future Issuances
Exercise of outstanding stock options	13,884
Unvested RSUs and RSAs	2,445,307
Unvested PSUs and PRSAs (at 200% maximum payout)	4,098,106
Issuance of stock-based awards under the Equity Plans	312,137

NOTE 12. Segment and Revenue Information

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, the Chief Executive Officer, to assess performance and to allocate resources. 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.

Significant Customers

Significant customers are defined as customers representing greater than 10% of consolidated revenue. Significant portions of the Company’s sales are concentrated among a limited number of customers. Revenue from two and three of our significant customers represented an aggregate of 62% and 68% of our consolidated revenue for the three months ended March 31, 2022 and 2021, respectively. Revenue from two and three of our significant customers represented an aggregate of 64% and 69% of our consolidated revenue for the six months ended March 31, 2022 and 2021, respectively. The percentage from significant customers decreased due to lower Aerospace and Defense revenue.

The duration, severity, and future impact of the COVID-19 pandemic is highly uncertain and could result in significant disruptions to the business operations of the Company’s customers. If one or more of these significant customers significantly decreases their orders for the Company’s products, or if we are unable to deliver finished products to the customer in connection with such orders, the Company’s business could be materially and adversely affected.

NOTE 13. Subsequent Event

17

On April 29, 2022, we completed the previously announced acquisition of the L3Harris Technologies, Inc. (“L3H”) Space and Navigation business (“S&N”) pursuant to that certain Sale Agreement, dated as of February 14, 2022 (as amended, the “Sale Agreement”), entered into by and among the Company, Ringo Acquisition Sub, Inc. and L3H, pursuant to which we acquired certain intellectual property, assets, and liabilities of S&N for aggregate consideration of approximately $5.0 million, exclusive of transaction costs and expenses and subject to certain post-closing working capital adjustments. In consideration of the recency of the completion of the purchase, we have not completed the initial accounting for the business combination and have not evaluated stand-alone acquiree revenue and earnings in the pre-acquistion period for supplemental pro-forma presentation and, accordingly have not included disclosure related to such items.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion of our financial condition and results of operations in conjunction with the financial statements and the notes thereto included in Financial Statements under Item 1 within this Quarterly Report. The following discussion contains forward-looking statements that reflect our plans, estimates, and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. See Cautionary Statement Regarding Forward-Looking Statements preceding Item 1 of this Quarterly Report.

Business Overview

EMCORE Corporation (referred to herein, together with its subsidiaries, as the “Company,” “we,” “our,” or “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 ("CATV") industry.

We pioneered the linear fiber optic transmission technology that enabled the world’s first delivery of CATV directly on fiber, and today are a leading provider of advanced mixed-signal products serving the aerospace and defense and broadband communications markets. The mixed-signal technology, at the heart of our broadband communications products, is shared with our fiber optic gyroscopes ("FOG") and inertial sensors to provide the aerospace and defense markets with state-of-the-art navigation systems technology.

These facilities support our vertically-integrated manufacturing strategy for quartz and FOG 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. Broadband is comprised of three product lines: (i) CATV Lasers and Transmitters, (ii) Chip Devices, and (iii) Other Optical Products.

Recent Developments

Acquisition of L3Harris Space & Navigation Business

On April 29, 2022, we completed the previously announced acquisition of the L3Harris Technologies, Inc. (“L3H”) Space and Navigation business (“S&N”) pursuant to that certain Sale Agreement, dated as of February 14, 2022 (as amended, the “Sale Agreement”), entered into by and among the Company, Ringo Acquisition Sub, Inc. and L3H, pursuant to which we acquired certain intellectual property, assets, and liabilities of S&N for aggregate consideration of approximately $5.0 million, and exclusive of transaction costs and expenses and subject to certain post-closing working capital adjustments.

COVID-19

We are subject to ongoing risks and uncertainties as a result of the COVID-19 pandemic. The full extent of the COVID-19 impact on operational and financial performance is highly 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. For example, during the three months ended March 31, 2022, unexpected delays and cancellations of key component deliveries required us to source critical components from alternative sources on short schedules and at increased prices. These and other actions resulting from the effects of COVID-19 may continue in the future and cause additional challenges to and disruptions of our business, inventory levels, operating results, and cash flows.

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 revenue, and cash flows.

Equity Offering

On February 16, 2021, we closed an 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

19

expenses, of approximately $33.1 million. The shares were sold by us pursuant to an underwriting agreement with Cowen and Company, LLC, dated February 10, 2021.

Hytera and Fastrain 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 “Hytera 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, “Hytera”), pursuant to which Hytera agreed to purchase from us certain CATV module and transmitter manufacturing equipment (the “Equipment”) that we owned and that was located at the manufacturing facility of our wholly-owned subsidiary, EMCORE Optoelectronics (Beijing) Co, Ltd., a corporation formed under the laws of the P.R.C..

On August 9, 2021, we entered into an Asset Purchase Agreement (the “Fastrain Asset Purchase Agreement”) with each of Shenzhen Fastrain Technology Co., Ltd., a corporation formed under the laws of the P.R.C. (“Shenzhen Fastrain”), and Hong Kong Fastrain Company Limited, a limited liability company incorporated in Hong Kong (“HK Fastrain”, and together with Shenzhen Fastrain, collectively, “Fastrain”), pursuant to which, among other items, Fastrain agreed to purchase all of the Equipment subject to the Hytera Asset Purchase Agreement, along with certain other equipment owned by us, for an aggregate price of $6.2 million, of which (a) $4.9 million had been paid to us as of March 31, 2022 and (b) $1.1 million remains to be paid to us in connection with the Equipment that is expected to be transferred pursuant to one or more closings occurring in the quarter ending June 30, 2022.

Concurrently with the execution of the Fastrain Asset Purchase Agreement, we and Fastrain entered into a Manufacturing Supply Agreement, dated August 9, 2021 (as amended, the “Fastrain Manufacturing Agreement”), pursuant to which Fastrain agreed to manufacture for us, from a manufacturing facility or facilities located in Thailand or Malaysia and for an initial term ending on December 31, 2025, the CATV Laser and Transmitter products set forth in the Fastrain Manufacturing Agreement. In the Fastrain Manufacturing Agreement, (a) we agreed to pay certain shortfall penalties in the event that orders for manufactured products are below certain thresholds beginning in calendar year 2021 and continuing through calendar year 2025, and (b) Fastrain agreed to pay certain surplus bonuses to us in the event that deliveries for manufactured products in either of the 24 month periods beginning on January 1, 2021 and ending on December 31, 2022 or beginning on January 1, 2023 and ending on December 31, 2024 exceed certain thresholds. No such shortfall penalties had accrued or become payable as of the quarter ended March 31, 2022.

The transfer of the Equipment currently owned by us is expected to occur during the quarter ending June 30, 2022, with corresponding payments totaling $1.3 million expected to be received during the quarter ending June 30, 2022.

Aerospace and Defense

For the three months ended March 31, 2022, our Aerospace and Defense revenue decreased $4.1 million, or 31.4%, compared to the same period in the prior year, primarily due to a $2.8 million decrease in Defense Optoelectronics product line revenue primarily due to program delays and supply chain disruptions.

For the six months ended March 31, 2022, our Aerospace and Defense revenue decreased $7.9 million, or 29.4%, compared to the same period in the prior year, primarily due to a $5.4 million decrease in Defense Optoelectronics product line revenue primarily due to program delays and supply chain disruptions.

21

Broadband

For the three months ended March 31, 2022, our Broadband revenue decreased $1.6 million, or 6.4%, compared to the same period in the prior year, primarily due to a $1.8 million decrease in Other Optical Products revenue due to decreased customer demand. We anticipate Broadband revenue to continue to be challenged in the near future due in part to inventory levels in the channel.

For the six months ended March 31, 2022, our Broadband revenue increased $10.9 million, or 24.2%, compared to the same period in the prior year, primarily driven by a $11.0 million increase in CATV Lasers and Transmitters revenue due to increased customer demand.

Gross Profit

(in thousands, except percentages)	2022		2021		Change
Aerospace and Defense	$	1,233	$	3,775	$	(2,542)	(67.3)	%
Broadband	7,784		10,859		(3,075)		(28.3)
Total gross profit	$	9,017	$	14,634	$	(5,617)	(38.4)	%

	For the Six Months Ended March 31,
(in thousands, except percentages)	2022		2021		Change
Aerospace and Defense	$	2,917	$	7,875	$	(4,958)	(63.0)	%
Broadband	21,897		19,331		2,566		13.3
Total gross profit	$	24,814	$	27,206	$	(2,392)	(8.8)	%

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.

For the three months ended March 31, 2022 and 2021, consolidated gross margins were 27.6% and 38.1%, respectively. For each of the three months ended March 31, 2022 and 2021, stock-based compensation expense within cost of revenue totaled $0.2 million.

For the six months ended March 31, 2022 and 2021, consolidated gross margins were 33.1% and 37.9%, respectively. For each of the six months ended March 31, 2022 and 2021, stock-based compensation expense within cost of revenue totaled $0.3 million.

Aerospace and Defense

For the three months ended March 31, 2022, Aerospace and Defense gross profit decreased $2.5 million, or 67.3%, compared to the same period in the prior year. For the three months ended March 31, 2022 and 2021, Aerospace and Defense gross margin was 13.7% and 28.7%, respectively. Gross profit and margin decreased in the three months ended March 31, 2022 primarily due to lower FOG and Defense Optoelectronics revenue and higher manufacturing costs. Higher manufacturing costs were a result of our change in contract manufacturer, as well as under-absorption of fixed overhead at our Alhambra manufacturing facility.

For the six months ended March 31, 2022, Aerospace and Defense gross profit decreased $5.0 million, or 63.0%, compared to the same period in the prior year. For the six months ended March 31, 2022 and 2021, Aerospace and Defense gross margin was 15.4% and 29.4%, respectively. Gross profit and margin decreased in the six months ended March 31, 2022 primarily due to lower Quartz MEMS and Defense Optoelectronics revenue, and a change in contract manufacturer and under-absorption of fixed overhead for Defense Optoelectronics.

Broadband

22

For the three months ended March 31, 2022, Broadband gross profit decreased $3.1 million, or 28.3%, compared to the same period in the prior year. For the three months ended March 31, 2022 and 2021, Broadband gross margin was 32.9% and 43.0%, respectively. Gross profit and margin decreased in the three months ended March 31, 2022 due to lower revenue of $1.6 million, higher material costs, and under-absorption of fixed overhead at our Chinese manufacturing facility and at our Alhambra wafer fab.

For the six months ended March 31, 2022, Broadband gross profit increased $2.6 million, or 13.3%, compared to the same period in the prior year. For the six months ended March 31, 2022 and 2021, Broadband gross margin was 39.1% and 42.9%, respectively. Gross profit increased while gross margin decreased in the six months ended March 31, 2022 due to higher revenue mixed with higher material costs and under-absorption of fixed overhead costs.

Selling, General and Administrative

Selling, general, and administrative ("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.

For the three months ended March 31, 2022, SG&A expense increased by $1.5 million compared to the same period in the prior year, primarily driven by higher compensation, professional fees including acquisition related expenses, and travel expenses. For the three months ended March 31, 2022 and 2021, SG&A expenses were 23.2% and 15.8% as a percentage of revenue, respectively. For the three months ended March 31, 2022 and 2021, stock-based compensation expense within SG&A totaled $0.8 million and $0.5 million, respectively.

For the six months ended March 31, 2022, SG&A expense increased by $2.9 million compared to the same period in the prior year, primarily driven by higher compensation, professional fees including acquisition related expenses, and travel expenses. For the six months ended March 31, 2022 and 2021, SG&A expenses were 19.7% and 16.5% as a percentage of revenue, respectively. For the six months ended March 31, 2022 and 2021, stock-based compensation expense within SG&A totaled $1.5 million and $1.1 million, respectively.

Research and Development

Research and development ("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. 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.

For the three months ended March 31, 2022, R&D expense increased by $0.8 million compared to the same period in the prior year, primarily driven by increased compensation and project costs. For the three months ended March 31, 2022 and 2021, R&D expenses were 13.9% and 9.8% as a percentage of revenue, respectively. For each of the three months ended March 31, 2022 and 2021, stock-based compensation expense within R&D totaled $0.2 million.

For the six months ended March 31, 2022, R&D expense increased by $1.1 million compared to the same period in the prior year, primarily driven by increased compensation and allocated facility costs. For the six months ended March 31, 2022 and 2021, R&D expenses were 12.2% and 11.2% as a percentage of revenue, respectively. For each of the six months ended March 31, 2022 and 2021, stock-based compensation expense within R&D totaled $0.4 million.

For the three months ended March 31, 2022 and 2021, Aerospace and Defense R&D expense was $4.0 million and $3.2 million, respectively. For the three months ended March 31, 2022 and 2021, Broadband R&D expense was $0.5 million and $0.6 million, respectively.

For the six months ended March 31, 2022 and 2021, Aerospace and Defense R&D expense was $8.2 million and $6.8 million, respectively. For the six months ended March 31, 2022 and 2021, Broadband R&D expense was $1.0 million and $1.2 million, respectively.

Severance

23

For the three and six months ended March 31, 2022, we incurred a severance charge of $20 thousand and $1.3 million, respectively. The majority of the $1.3 million is associated with the planned shutdown of manufacturing operations in Beijing, China.

(Gain) Loss on Sale of Assets

During the three months ended March 31, 2022 and 2021, we sold certain equipment and incurred a (gain) loss on sale of assets of $(0.8) million and $0.2 million, respectively. During the six months ended March 31, 2022 and 2021, we sold certain equipment and incurred a (gain) loss on sale of assets of $(0.6) million and $0.2 million, respectively. We have agreements to sell additional equipment and these assets are classified as assets held for sale. The remaining balance as of March 31, 2022 totaled $0.7 million.

Operating (Loss) Income

Operating (loss) income represents revenue less the cost of revenue and direct operating expenses incurred. Operating (loss) income is a measure that executive management uses to assess performance and make decisions. For the three months ended March 31, 2022 and 2021, operating (loss) income was (7.1)% and 11.9% as a percentage of revenue, respectively. For the six months ended March 31, 2022 and 2021, operating income was 0.2% and 9.9% as a percentage of revenue, respectively.

Order Backlog

Our 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. Historically, for our CATV Lasers and Transmitters product line, products have typically shipped within the same quarter in which a purchase order is received, and therefore 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. In addition, demand for our CATV Lasers and Transmitters products has historically been cyclical, and therefore future revenue trends for this product line are difficult to determine. With respect to our Aerospace and Defense product lines, revenue growth is dependent to a significant extent on customer program schedules.

Liquidity and Capital Resources

We continue to experience an accumulated deficit, but have managed our liquidity position through the sale of assets and cost reduction initiatives, as well as borrowings from our Credit Facility and capital markets transactions. As of March 31, 2022, cash and cash equivalents totaled $80.9 million and net working capital totaled $117.2 million. Net working capital, calculated as current assets (including inventory) minus current liabilities, is a financial metric we use which represents available operating liquidity.

We have taken a number of actions to continue to support our operations and meet our obligations, including:

•We maintain a credit facility with Wells Fargo that provides us with a revolving credit line of up to $15.0 million that can be used as required for operations, subject to certain liquidity and availability requirements. The Credit Facility had $6.1 million available for borrowing as of March 31, 2022. See Note 8 - Credit Facility and Debt in the notes to the condensed consolidated financial statements for additional information regarding the Credit Facility.

•On February 16, 2021, we closed our offering of 6,655,093 shares of our common stock at a price of $5.40 per share, resulting in net proceeds to us from the offering of $33.1 million. See Management’s Discussion and Analysis of Financial Condition and Results of Operations Recent Developments under the heading "Equity Offering" for additional information regarding the equity offering.

•In October 2019, we entered into the Hytera Asset Purchase Agreement pursuant to which we agreed to sell certain of our CATV Lasers and Transmitters manufacturing equipment for purposes of outsourcing manufacturing of our CATV Lasers and Transmitters product lines to Hytera. In August 2021, we entered into the Fastrain Asset Purchase Agreement, pursuant to which, among other items, Fastrain agreed to purchase the same equipment subject to the Hytera Asset Purchase Agreement, along with additional equipment, for aggregate consideration of $6.2 million. See Management’s Discussion and Analysis of Financial Condition and Results of Operations - Recent Developments under the heading "Hytera and Fastrain Transactions" for additional information regarding the transactions with Hytera and Fastrain.

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 (or a replacement facility, if any, to the extent the expiration of the Credit Facility occurs in

24

May 2022) 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 issuance date of these financial statements.

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 and real estate, 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 earnings.

Cash Flow

Operating Activities

	For the Six Months Ended March 31,
(in thousands, except percentages)	2022		2021		Change
Net cash provided by operating activities	$	11,535	$	1,772	$	9,763	551.0	%

For the six months ended March 31, 2022, our operating activities provided cash of $11.5 million due to our net income of $0.2 million, positive adjustments for non-cash charges of $4.4 million, and improvements in our working capital components of $6.9 million. Non-cash charges primarily consisted of depreciation and amortization expense of $2.0 million and stock based compensation expense of $2.2 million.

For the six months ended March 31, 2021, our operating activities provided cash of $1.8 million, primarily due to our net income of $7.0 million, and positive adjustments for non-cash charges of $3.9 million offset by changes in our working capital components of $9.1 million. Non-cash charges primarily consisted of depreciation and amortization expense of $2.0 million and stock based compensation expense of $1.8 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. Accounts receivable balances have fluctuated historically 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. Inventory balances have fluctuated historically due to the timing of customer orders and product shipments, changes in internal forecasts related to customer demand, as well as adjustments related to excess and obsolete 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 accrued expense accounts have primarily related to changes in the timing of actual compensation payments, receipt or application of advanced payments, adjustments to warranty accrual, and accruals related to professional fees.

Except as described below, all of your Restricted Stock Units will terminate for no consideration at the end of the Performance Period if the Company achieves a Total Shareholder Return that is equal to or less than fifty percent (50%) of the Total Shareholder Return for the Index. If the Company achieves a Total Shareholder Return relative to the Index for the Performance Period between the percentages listed in the table above, the percentage of your Restricted Stock Units that will be eligible to become vested and nonforfeitable will be pro-rated on a straight-line basis between the closest two percentages listed in the table above. The maximum percentage of your Restricted Stock Units that may be eligible to become vested and nonforfeitable is the maximum percentage listed in the table above. Any of your Restricted Stock Units that do not become eligible to become vested and nonforfeitable at the end of the Performance Period based on the Company’s Total Shareholder Return for the Performance Period will automatically terminate for no consideration at the end of the Performance Period.

(b)    Continued Service Vesting Condition. In addition to achievement of the Total Shareholder Return performance-vesting requirements set forth above, in order for any of your Restricted Stock Units to become vested and nonforfeitable, you must continue to be an Eligible Person through the applicable vesting date. Unless this Agreement provides to the contrary, none of the Restricted Stock Units will become vested and nonforfeitable after you cease to be an Eligible Person, and any Restricted Stock Units that are nonvested and forfeitable as of the date you cease to be an Eligible Person shall terminate for no consideration.

(c)    Change in Control. If a Change in Control occurs while any of your Restricted Stock Units are outstanding, the following provisions shall apply:

(i)    If the Change in Control occurs after the end of the Performance Period but before any Restricted Stock Units that have become vested and nonforfeitable based on the Company’s Total Shareholder Return performance for the completed Performance Period have been paid, such vested and nonforfeitable Restricted Stock Units will be paid as provided for in Section 2(e) below.

(ii)    If the Change in Control occurs during the Performance Period while any of your Restricted Stock Units are outstanding, the Performance Period (an “Adjusted Performance Period”) will be deemed to end on the day immediately preceding the Change in Control and performance will be measured based on the Company’s Total Shareholder Return relative to the Index through the date of the Change in Control, provided that (1) instead of using an average stock price to measure the Company’s Total Shareholder Return at the end of the Adjusted Performance Period, the Company’s Total Shareholder Return at the end of the Adjusted Performance Period will be measured using the price per share of Common Stock to be paid in the Change in Control in accordance with the definitive agreement governing the transaction constituting the Change in Control (or, in the absence of such agreement, the closing price per share of Common Stock on the last trading day prior to the Change in Control, as reported at the close of regular trading on the principal exchange on which the Common Stock is listed), and (2) the Total Shareholder Return for the Index shall be determined in accordance with the definition of Total Shareholder Return, but using the day immediately preceding the Change in Control as the last day of the Adjusted Performance Period. Any Restricted Stock Units that become eligible to become vested and nonforfeitable based on the Company’s Total Shareholder Return performance for the Adjusted Performance Period (or if you are a party to an employment agreement with the Company (an “Employment Agreement”) that entitles you to vest in a minimum of the target number of Restricted Stock Units for the Adjusted Performance Period as a result of a Change in Control or qualifying termination of employment following a Change in Control, the target number of Restricted Stock Units if greater) shall be referred to as “Adjusted Performance Period Units”). For the avoidance of doubt, if you are party to an Employment Agreement that entitles you to vest in a specified percentage of your outstanding equity awards as a result of a Change in Control or qualifying termination of employment following a Change in Control, the Employment Agreement shall entitle you to vest in the Adjusted Performance Period Units as determined above.

(iii)    Any Restricted Stock Units for the Adjusted Performance Period that do not become Adjusted Performance Period Units shall terminate at the end of the Adjusted Performance Period for no consideration.

(iv)    If you are a party to an Employment Agreement that entitles you to vest in the Adjusted Performance Period Units for the Adjusted Performance Period solely as a result of a Change in Control, you will be entitled to vest in the number of Adjusted Performance Period Units becoming vested and nonforfeitable pursuant to the terms of your Employment Agreement (the “Accelerated Adjusted Units”). The Accelerated Adjusted Units will be paid as provided for in Section 2(e) below.

3

(v)    Any Adjusted Performance Period Units for the Adjusted Performance Period that are not Accelerated Adjusted Units (the “Time-Based Adjusted Units”), will become vested and nonforfeitable on the last day of the original Performance Period (before any adjustment), subject to you continuing to be an Eligible Person through such date. In addition, (1) if you suffer an involuntary termination without Cause within two years following the Change in Control and prior to the last day of the original Performance Period, all of your unvested Time-Based Adjusted Units will become vested and nonforfeitable as of the date of your termination without Cause, and (2) if you are party to an Employment Agreement that entitles you to vest in any Time-Based Adjusted Units as a result of a qualifying termination of employment following a Change in Control and you experience a qualifying termination of employment prior to the last day of the original Performance Period, the applicable number of Time-Based Adjusted Units becoming vested pursuant to the terms of your Employment Agreement will become vested and nonforfeitable as of the date of your qualifying termination of employment. Any Time-Based Adjusted Units becoming vested and nonforfeitable will be paid as provided for in Section 2(e) below.

(vi)    Notwithstanding anything to the contrary in this Agreement or the Plan, in the event of a Change in Control or other event specified in Section 7.2 of the Plan in which the Restricted Stock Units are not assumed, all of the Adjusted Performance Period Units shall become vested and nonforfeitable as of the last day of the Adjusted Performance Period and will be paid as provided for in Section 2(e) below. For the avoidance of doubt and notwithstanding anything to the contrary in the Plan, any Restricted Stock Units for an Adjusted Performance Period that do not become Adjusted Performance Period Units shall terminate at the end of the Adjusted Performance Period.

(d)    Termination of Service. If you cease to be an Eligible Person for any reason, all Restricted Stock Units that are not then vested and nonforfeitable will, after giving effect to any accelerated vesting as a result of your ceasing to be an Eligible Person, be immediately forfeited for no consideration.

(e)    Settlement. Any Restricted Stock Units subject to this Award that become vested and nonforfeitable shall be paid in an equivalent number of whole shares of Common Stock (with any fractional Restricted Stock Units rounded down to the nearest whole number of shares of Common Stock) as soon as practicable following the applicable vesting date, but in any event no later than the 15th day of the third calendar month following the end of the calendar year in which the vesting date occurs; provided that any Restricted Stock Units that become vested and nonforfeitable in connection with or following a Change in Control or other corporate transaction specified in Section 7.2 of the Plan will be paid no later than the 30th day following the applicable vesting date. Upon issuance, such shares of Common Stock may be sold, transferred, pledged, assigned or otherwise alienated or hypothecated in compliance with applicable law, this Agreement and any other agreement to which such shares are subject. Your settlement rights pursuant to this Agreement shall be no greater than the right of any unsecured general creditor of the Company. The Company will not be required to issue fractional shares of Common Stock upon settlement of the Restricted Stock Units.

3.    Restrictions on Transfer. You may not sell, assign, transfer, pledge, hedge, hypothecate, encumber or dispose of in any way (whether by operation of law or otherwise) any Restricted Stock Units, and Restricted Stock Units may not be subject to execution, attachment or similar process. Any sale or transfer, or purported sale or transfer, shall be null and void. The

4

Company will not be required to recognize on its books any action taken in contravention of these restrictions.

4.    Issuance of Shares.

(a)    Notwithstanding any other provision of this Agreement, you may not sell the shares of Common Stock acquired upon vesting of the Restricted Stock Units unless such shares are registered under the Securities Act, or, if such shares are not then so registered, such sale would be exempt from the registration requirements of the Securities Act. The sale of such shares must also comply with other applicable law and any applicable insider trading policy of the Company governing the Common Stock and you may not sell the shares of Common Stock if the Company determines that such sale would not be in material compliance with such applicable law or insider trading policy.

(b)    The shares of Common Stock issued in settlement of the Restricted Stock Units shall be registered in your name. The Company will deliver a share certificate to you, or deliver shares electronically or in certificate form to your designated broker on your behalf. If you are deceased (or in case of your Disability and if necessary) at the time that a delivery of share certificates is to be made, the certificates will be delivered to your executor, administrator, legally authorized guardian or personal representative. The Company may at any time place legends referencing any applicable law restrictions on all certificates representing shares of Common Stock issued pursuant to this Agreement, and the certificate shall bear such restrictive legends or restrictions as the Company, in its sole discretion, shall require. You will, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to this Agreement in your possession in order to carry out the provisions of this Section 4(b).

(c)    The grant of the Restricted Stock Units and the shares of Common Stock issued in settlement of the Restricted Stock Units will be subject to and in compliance with all applicable requirements of applicable law with respect to such securities. No shares of Common Stock may be issued hereunder if the issuance of such shares would constitute a violation of any applicable law. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance of any shares subject to the Restricted Stock Units shall relieve the Company of any liability in respect of the failure to issue such shares as to which such requisite authority shall not have been obtained. As a condition to the settlement of the Restricted Stock Units, the Company may require you to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law and to make any representation or warranty with respect thereto as may be requested by the Company.

5.    Tax Withholding1. The Company or the Employer shall be entitled to require a cash payment by or on your behalf (including, without limitation, subject to such procedures as

1 For Section 16 officers, Section 5 to read as follows “Unless (1) otherwise determined by the Administrator at any time after the Grant Date or (2) you have previously notified the Chief Financial Officer of the Company (or his designee) that you will pay the amount of any applicable federal, state or local tax law withholding taxes directly to the Company in cash, upon any payment of shares of Common Stock in respect of the Restricted Stock Units, the Company shall automatically reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of whole shares, valued at their then fair market value, to satisfy any withholding obligations of the Company and the Employer with respect to such distribution of shares at the applicable withholding rates. In the event that the Administrator determines not to satisfy, or the Company cannot legally satisfy, such withholding obligations by such reduction of shares, or in the event of a cash payment or any other withholding event in respect of the Restricted Stock Units, the Company or the Employer shall be entitled to require a cash payment by or on your behalf and/or to deduct from other compensation payable to you any sums required by federal, state or local tax law to be withheld with respect to such distribution or payment”

5

the Administrator may adopt, pursuant to a broker-assisted “cashless” arrangement with a third party who facilitates the sale of shares of Common Stock deliverable upon any payment of Restricted Stock Units) and/or to deduct from other compensation payable to you any sums required by federal, state or local tax law to be withheld with respect to the grant, vesting or payment of the Restricted Stock Units in whole or in part. The Company may, in its discretion, agree that it will, upon any payment of shares of Common Stock in respect of the Restricted Stock Units, automatically reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of whole shares, valued at their then fair market value, to satisfy any withholding obligations of the Company and the Employer with respect to such distribution of shares at the applicable withholding rates.

6.    Adjustments for Corporate Transactions and Other Events.

(a)    Adjustment Events.Upon an event specified in Section 7.1 of the Plan, the number, amount and type of shares of Common Stock (or other securities or property) subject to your Restricted Stock Units will, without further action of the Administrator, be adjusted to reflect such event pursuant to the provisions of Section 7.1 of the Plan. The Administrator may make adjustments, in its discretion, to address the treatment of fractional shares with respect to the Restricted Stock Units as a result of the adjustment event. Adjustments under this Section 6 will be made by the Administrator, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional Restricted Stock Units will result from any such adjustments.

(b)    Binding Nature of Agreement. The terms and conditions of this Agreement will apply with equal force to any additional and/or substitute securities received by you in exchange for, or by virtue of your granting of, the Restricted Stock Units, whether as a result of any adjustment event or other similar event, except as otherwise determined by the Administrator. If the Restricted Stock Units are converted into or exchanged for, or stockholders of the Company receive by reason of any distribution in total or partial liquidation or pursuant to any merger of the Company or acquisition of its assets, securities of another entity, or other property (including cash), then the rights of the Company under this Agreement will inure to the benefit of the Company’s successor, and this Agreement will apply to the securities or other property received upon such conversion, exchange or distribution in the same manner and to the same extent as the Restricted Stock Units.

7.    Dividend Equivalent Rights. As of each date that the Company pays an ordinary cash dividend on its outstanding Common Stock for which the related record date occurs after the Grant Date and prior to the date all Restricted Stock Units subject to the Award have either been paid or have terminated, the Company shall credit you with an additional number of Restricted Stock Units equal to (a) the amount of the ordinary cash dividend paid by the Company on a single share of Common Stock on that date, multiplied by (b) the number of Restricted Stock Units subject to the Award outstanding and unpaid as of such record date (including any Restricted Stock Units previously credited under this Section 7 and with such total number subject to adjustment pursuant to Section 7.1 of the Plan and this Agreement), divided by (c) the closing price of a share of Common Stock on that date. Any Restricted Stock Units credited pursuant to the foregoing provisions of this Section 7 will be subject to the same vesting, payment, termination and other terms, conditions and restrictions as the original Restricted Stock Units to which they relate. No crediting of Restricted Stock Units will be made pursuant to this Section 7 with respect to any Restricted Stock Units which, as of the related record date, have either been paid or have terminated.

6

8.    No Right to Continued Employment or Service. The Award shall not confer upon you any right to be retained as an employee or service provider, nor restrict in any way the right of your Employer, which right is hereby expressly reserved, to terminate your employment or service relationship at any time with or without Cause (regardless of whether such termination results in (a) the failure of any Award to vest; (b) the forfeiture of any unvested or vested portion of any Award; and/or (c) any other adverse effect on your interests under the Plan). Nothing in the Plan or this Agreement shall confer on you the right to receive any future Awards under the Plan.

9.    No Rights as Stockholder. You shall not have any rights as a stockholder of the Company with respect to any shares of Common Stock corresponding to the Restricted Stock Units granted hereby unless and until shares of Common Stock are issued to you in respect thereof. No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such certificate or certificates are issued, except as provided in Section 6 and Section 7 of this Agreement.

10.    The Company’s Rights. The existence of the Restricted Stock Units does not affect in any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, including that of its affiliates, or any merger or consolidation of the Company or any affiliate, or any issue of bonds, debentures, preferred or other stocks with preference ahead of or convertible into, or otherwise affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company or any affiliate, or any sale or transfer of all or any part of the Company’s or any affiliate’s assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

11.    Entire Agreement. This Agreement, inclusive of the Plan incorporated into this Agreement, contains the entire agreement between you, your Employer and the Company with respect to the Restricted Stock Units. Any and all existing oral or written agreements, representations, warranties, written inducements, or other communications made prior to the execution of this Agreement by any person with respect to the Award or the Restricted Stock Units are superseded by this Agreement and are void and ineffective for all purposes.

12.    Conformity with Plan. This Agreement is intended to conform in all respects with, and is subject to all applicable provisions of, the Plan. In the event of any ambiguity in this Agreement or any matters as to which this Agreement is silent, the Plan will govern.

13.    Amendment. This Agreement may be amended from time to time by the Administrator in its discretion; provided, however, that this Agreement may not be modified in a manner that would have a materially adverse effect on the Restricted Stock Units as determined in the discretion of the Administrator, except as provided in the Plan or in any other written document signed by you and the Company. This Agreement may not be amended, modified or supplemented orally.

14.    Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of New Jersey applicable to contracts executed and to be performed entirely within such state, without regard to the conflict of law provisions thereof.

15.    Severability. If a court of competent jurisdiction determines that any portion of this Agreement is in violation of any statute or public policy, then only the portions of this Agreement which violate such statute or public policy shall be stricken, and all portions of this Agreement which do not violate any statute or public policy shall continue in full force and effect. Further, it is the parties’ intent that any court order striking any portion of this Agreement

7

should modify the terms as narrowly as possible to give as much effect as possible to the intentions of the parties’ under this Agreement.

16.    Further Assurances. You agree to use your reasonable and diligent best efforts to proceed promptly with the transactions contemplated herein, to fulfill the conditions precedent for your benefit or to cause the same to be fulfilled and to execute such further documents and other papers and perform such further acts as may be reasonably required or desirable to carry out the provisions hereof and the transactions contemplated herein. The Company may require you to furnish or execute such other documents as the Company shall reasonably deem necessary to comply with or satisfy the requirements of applicable law.

17.    Investment Representation. If at the time of settlement of all or part of the Restricted Stock Units, the Common Stock is not registered under the Securities Act and/or there is no current prospectus in effect under the Securities Act with respect to the Common Stock, you shall execute, prior to the issuance of any shares of Common Stock in settlement of the Restricted Stock Units to you by the Company, an agreement (in such form as the Administrator may specify) in which you, among other things, represent, warrant and agree that you are acquiring the shares acquired under this Agreement for your own account, for investment only and not with a view to the resale or distribution thereof, that you have knowledge and experience in financial and business matters, that you are capable of evaluating the merits and risks of owning any shares of Common Stock acquired under this Agreement, that you are a person who is able to bear the economic risk of such ownership and that any subsequent offer for sale or distribution of any of such shares shall be made only pursuant to (a) a registration statement on an appropriate form under the Securities Act, which registration statement has become effective and is current with regard to the shares being offered or sold, or (b) a specific exemption from the registration requirements of the Securities Act, it being understood that to the extent any such exemption is claimed, you shall, prior to any offer for sale or sale of such shares, obtain a prior favorable written opinion, in form and substance satisfactory to the Administrator, from counsel for or approved by the Administrator, as to the applicability of such exemption thereto.

18.    Headings. Section headings are used in this Agreement for convenience of reference only and shall not affect the meaning of any provision of this Agreement.

Notwithstanding the foregoing, if you are a party to an Employment Agreement, “Cause” shall have the meaning, if any, specified in your Employment Agreement.

(c)    “Change in Control” means the occurrence of any of the following:

(i)    an acquisition in one transaction or a series of related transactions (other than directly from the Company or pursuant to Awards granted under the Plan or other similar awards granted by the Company under predecessor equity incentive plans) of any Voting Securities by any Person, immediately after which such Person has Beneficial Ownership of fifty percent (50%) or more of the combined voting power of the Company’s then outstanding Voting Securities; provided, however, in determining whether a Change in Control has occurred hereunder, Voting Securities which are acquired in a Non-Control Acquisition shall not constitute an acquisition that would cause a Change in Control;

(ii)    the individuals who, immediately prior to the effective date of the Plan, are members of the Board (the “Incumbent Board”), cease for any reason to constitute at least a majority of the members of the Board; provided, however, that if the election, or nomination for election, by the Company’s common stockholders, of any new director was approved by a vote of at least a majority of the Incumbent Board, such new director shall, for purposes of the Plan, be considered as a member of the Incumbent Board; provided further, however, that no individual shall be considered a member of the Incumbent Board if such individual initially assumed office as a result of either an actual or threatened “Election Contest” (as described in Rule 14a-11 promulgated under the Exchange Act) or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board (a “Proxy Contest”) including by reason of any agreement intended to avoid or settle any Election Contest or Proxy Contest; or

(C)    the sale or other disposition of all or substantially all of the assets or business of the Company to any Person (other than a transfer to a Related Entity or the distribution to the Company’s stockholders of the stock of a Related Entity or any other assets).

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur solely because any Person (the “Subject Person”) acquired Beneficial Ownership of fifty percent (50%) or more of the combined voting power of the then outstanding Voting Securities as a result of the acquisition of Voting Securities by the Company which, by reducing the number of Voting Securities then outstanding, increases the proportional number of shares Beneficially Owned by the Subject Persons, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of Voting Securities by the Company, and (1) before such share acquisition by the Company the Subject Person becomes the Beneficial Owner of any new or additional Voting Securities in a related transaction or (2) after such share acquisition by the Company the Subject Person becomes the Beneficial Owner of any new or additional Voting Securities which in either case increases the percentage of the then outstanding Voting Securities Beneficially Owned by the Subject Person, then a Change in Control shall be deemed to occur. Solely for purposes of this Change in Control definition, (x)

11

“Affiliate” shall mean, with respect to any Person, any other Person that, directly or indirectly, controls, is controlled by, or is under common control with, such Person; (y) any “Relative” (for this purpose, “Relative” means a spouse, child, parent, parent of spouse, sibling or grandchild) of an individual shall be deemed to be an Affiliate of such individual for this purpose; and (z) neither the Company nor any Person controlled by the Company shall be deemed to be an Affiliate of any holder of Common Stock.

(g)    “Person” means “person” as such term is used for purposes of Section 13(d) or 14(d) of the Exchange Act, including, without limitation, any individual, corporation, limited liability company, partnership, trust, unincorporated organization, government or any agency or political subdivision thereof, or any other entity or any group of Persons.

(h)    “Securities Act” means the Securities Act of 1933 and the rules promulgated thereunder, as amended.

(i)    “Total Shareholder Return” means the total shareholder return over the Performance Period for either the Company or the Index assuming that any dividends are reinvested in a company’s stock on the payment date. Except as provided in Section 2(c)(ii), (1) total shareholder return for the Company shall be calculated using (i) the average Company stock price at the close of regular trading on the principal exchange on which the stock is listed or traded for the 30-trading-day period ending with the last day on which the applicable exchange is open for trading preceding the first day of the Performance Period, and (ii) the average Company stock price at the close of regular trading on the principal exchange on which the stock is listed or traded for the 30-trading-day period ending with the last trading day of the Performance Period, and (2) total shareholder return for the Index will be measured over the same 30-trading day periods as for the Company.

(j)    “You”; “Your”. You means the recipient of the Restricted Stock Units as reflected in the first paragraph of this Agreement. Whenever the word “you” or “your” is used in any provision of this Agreement under circumstances where the provision should logically be construed, as determined by the Administrator, to apply to the estate, personal representative, or beneficiary to whom the Restricted Stock Units may be transferred by will or by the laws of descent and distribution, the words “you” and “your” will be deemed to include such person.

(k)    “Voting Securities” means all the outstanding voting securities of the Company entitled to vote generally in the election of the Board.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of BusinessEMCORE Corporation (referred to herein, together with its subsidiaries, as the “Company,” “we,” “our,” or “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 ("CATV") industry. We pioneered the linear fiber optic transmission technology that enabled the world’s first delivery of CATV directly on fiber, and today are a leading provider of advanced products that enable communications systems and service providers to meet growing demand for increased bandwidth and connectivity. The technology at the heart of our broadband communications products is shared with our fiber optic gyroscope (“FOG”) 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 micro-electromechanical system ("QMEMS") technology, in June 2019, we further expanded our portfolio of gyros and inertial sensors with SDI’s QMEMS gyro and accelerometer technology. We have fully vertically-integrated manufacturing capability through our indium phosphide ("InP") 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 our vertically-integrated manufacturing strategy for quartz and FOG 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 us which is unique in the optics industry.

Summary of Significant Accounting Policies

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation

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 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, 2021 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, 2021.

Significant Accounting Policies and Estimates

There have been no material changes in our significant accounting policies and estimates from those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 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.

Recent Accounting Pronouncements

We recently adopted the following accounting standards, which had the following impacts on our consolidated financial statements:

In December 2019, the FASB issued Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing various exceptions, such as the exception to the incremental approach for intra-period tax allocation when there is a loss from continuing operations and income or a gain from other items. The amendments in this update also simplify the accounting for income taxes related to income-based franchise taxes and require that an entity reflect enacted tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The new standard was effective for our fiscal year beginning

October 1, 2021. The adoption of this new standard did not have a material impact on the condensed consolidated financial statements.

Other accounting standards that have been issued or proposed by FASB and do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.

Credit Facilities and Debt

Credit Facility and Debt

Credit Facility

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 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. In February 2022, we entered into an extension wherein the Credit Facility is to mature in May 2022. The Credit Facility currently provides us with a revolving credit line of up to $15.0 million at an interest rate equal to LIBOR plus 1.75%, 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, 2022, there was no amount outstanding under this Credit Facility and the Company was in compliance with all financial covenants. Also, as of March 31, 2022, the Credit Facility had $0.5 million reserved for one outstanding stand-by letter of credit and $6.1 million available for borrowing.

Income and Other Taxes

Income and Other Taxes

During the three months ended March 31, 2022 and 2021, the Company recorded an income tax benefit of $117 thousand and income tax expense of $82 thousand, respectively. Income tax benefit during the three months ended March 31, 2022 is composed primarily of state minimum taxes. Income tax expense during the three months ended March 31, 2021 is composed primarily of state tax expense which is driven by the State of California's temporary suspension of net operating loss ("NOL") utilization.

During the six months ended March 31, 2022 and 2021, the Company recorded an income tax benefit of $2 thousand and income tax expense of $208 thousand. Income tax benefit for the six months ended March 31, 2022 is composed primarily of state minimum taxes. Income tax expense for the six months ended March 31, 2021 is composed primarily of state tax expense which is driven by the State of California's temporary suspension of NOL utilization.

For the three months ended March 31, 2022 and 2021 the effective tax rate on continuing operations was (5.0)% and 1.8%, respectively. For the six months ended March 31, 2022 and 2021 the effective tax rate on continuing operations was 1.1% and 2.9%, respectively. The tax rate for the three and six months ended March 31, 2022 is primarily driven by the state minimum taxes.

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, 2022 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 as of March 31, 2022. 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.

As of March 31, 2022 and September 30, 2021, we had no uncertain tax benefit reserved and no interest and penalties accrued as tax liabilities on our balance sheet. During the three and six months ended March 31, 2022 and 2021, there were no material increases or decreases in unrecognized tax benefits.

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 covers certain liabilities relating to 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.

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.

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, (a) a declaration that the Concord Property Sale included a non-cash component; (b) 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 the Company, The Resilience Fund IV, L.P., The Resilience Fund IV-A, L.P., Aerospace Newco Holdings, Inc. and Ember Acquisition Sub, Inc.; (c) recovery of Resilience’s costs and expenses; and (d) 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, (a) dismissal of the Resilience complaint and/or granting of judgment in favor of EMCORE with respect to the Resilience complaint, (b) 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, (c) a judicial determination of the respective rights and duties of us and Resilience under the SDI Purchase Agreement, (d) an award to us of costs and expenses and (e) 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.

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

•the 2019 Equity Incentive Plan.

We issue new shares of common stock to satisfy awards granted under our Equity Plans. In March 2022, our shareholders approved the Amended and Restated EMCORE Corporation 2019 Equity Incentive Plan, which was adopted by the Company’s Board of Directors in December 2021, 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 1.9 million 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, 2022 and 2021, our matching contribution in cash was $0.3 million. During each of the six months ended March 31, 2022 and 2021, our matching contribution in cash was $0.6 million.

Weighted average antidilutive options, unvested restricted RSUs and RSAs, unvested PSUs and ESPP shares excluded from the computation	75		1,536		72		1,331

Basic earnings per share ("EPS") is computed by dividing net (loss) income for the period by the weighted-average number of common stock outstanding during the period. Diluted EPS is computed by dividing net (loss) income for the period by the weighted average number of common stock outstanding during the period, plus the dilutive effect of outstanding restricted stock units ("RSUs") and restricted stock awards ("RSAs"), performance stock units ("PSUs"), stock options, and shares issuable under the employee stock purchase plan ("ESPP") as applicable pursuant to the treasury stock method. Certain of the

Company's outstanding share-based awards, noted in the table above, were excluded because they were anti-dilutive, but they could become dilutive in the future.

Future Issuances

As of March 31, 2022, we had common stock reserved for the following future issuances:

	Number of Common Stock Shares Available for Future Issuances
Exercise of outstanding stock options	13,884

Significant Customers

Significant customers are defined as customers representing greater than 10% of consolidated revenue. Significant portions of the Company’s sales are concentrated among a limited number of customers. Revenue from two and three of our significant customers represented an aggregate of 62% and 68% of our consolidated revenue for the three months ended March 31, 2022 and 2021, respectively. Revenue from two and three of our significant customers represented an aggregate of 64% and 69% of our consolidated revenue for the six months ended March 31, 2022 and 2021, respectively. The percentage from significant customers decreased due to lower Aerospace and Defense revenue.

The duration, severity, and future impact of the COVID-19 pandemic is highly uncertain and could result in significant disruptions to the business operations of the Company’s customers. If one or more of these significant customers significantly decreases their orders for the Company’s products, or if we are unable to deliver finished products to the customer in connection with such orders, the Company’s business could be materially and adversely affected.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

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 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, 2021 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, 2021.

Significant Accounting Policies and Estimates

Significant Accounting Policies and Estimates

There have been no material changes in our significant accounting policies and estimates from those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 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.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

We recently adopted the following accounting standards, which had the following impacts on our consolidated financial statements:

In December 2019, the FASB issued Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing various exceptions, such as the exception to the incremental approach for intra-period tax allocation when there is a loss from continuing operations and income or a gain from other items. The amendments in this update also simplify the accounting for income taxes related to income-based franchise taxes and require that an entity reflect enacted tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The new standard was effective for our fiscal year beginning

October 1, 2021. The adoption of this new standard did not have a material impact on the condensed consolidated financial statements.

Other accounting standards that have been issued or proposed by FASB and do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.

Legal Costs

Professional legal fees are expensed when incurred. We accrue for contingent losses when such losses are probable and reasonably estimable.
