Risk Factor Summary

Our business is subject to significant risks and uncertainties that make an investment in us speculative and risky. Below we summarize what we believe are the principal risk factors but these risks are not the only ones we face, and you should carefully review and consider the full discussion of our risk factors in the section titled “Risk Factors,” together with the other information in this Report. If any of the following risks actually occurs (or if any of those listed elsewhere in this Report occur), our business, reputation, financial condition, results of operations, revenue, and future prospects could be seriously harmed. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business.

•We have a history of losses, anticipate increasing our operating expenses in the future, and may not be able to achieve or maintain profitability.

•The Company may need to raise capital to finance its losses and negative cash flows from operations from the date of this filing and may continue to be dependent on additional capital raises, which may be unavailable on attractive terms, if at all, and could dilute your investment.

•Our quarterly results of operations are likely to vary from period to period, which could cause the market price of our common stock to fluctuate or decline.

•Our business could be adversely affected by the effects of health epidemics or pandemic, including the ongoing COVID-19 global pandemic.

•We may not be able to develop new technologies and products to satisfy changes in customer demand or industry standards, and our competitors could develop products that decrease the demand for our products.

•We must commit resources to development, design and production prior to receipt of purchase commitments and could lose some or all of the associated investment.

•We compete in highly competitive markets, and competitive pressures from existing and new companies may adversely impact our business and operating results.

•We rely on third-party channel partners to sell our products. If our partners fail to perform, our ability to sell our products and services could be limited, and if we fail to optimize our channel partner model going forward, our operating results could be harmed.

•We rely on limited sources of wafer fabrication, packaged products fabrication and product testing, the loss of which could delay and limit our product shipments.

•Because we depend on third-party manufacturers to build portions of our products, we are susceptible to manufacturing delays and pricing fluctuations that could prevent us from shipping customer orders on time, if at all, or on a cost-effective basis, which may result in the loss of sales, income and customers.

•Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense.

•Our current operations are concentrated in one location and in the event of an earthquake, terrorist attack or other disaster affecting this location or those of our major suppliers, our operations may be interrupted and our business may be harmed.

•The loss of one or more key employees or our inability to attract and retain qualified personnel could harm our business.

6

•If we fail to effectively manage our growth, our business, financial condition and results of operations would be harmed.

•We are subject to a number of risks associated with international sales and operations.

•We are subject to government regulation, including import, export and economic sanctions laws and regulations that may expose us to liability and increase our costs.

•Our sales to government customers subject us to uncertainties regarding fiscal funding approvals, renegotiations or terminations at the discretion of the government, as well as audits and investigations, which could result in litigation, penalties and sanctions including early termination, suspension and debarment.

•Any failure by us to protect our proprietary technologies or maintain the right to use certain technologies may negatively affect our ability to compete.

•If we fail to comply with our obligations under any license, collaboration or other agreements, we may be required to pay damages and could lose certain intellectual property rights.

•Any failure to maintain effective internal controls over our financial reporting could materially and adversely affect us.

•We have identified material weaknesses in our internal control over financial reporting that, if not properly remediated, could result in material misstatements in our consolidated financial statements in future periods.

•Our common stock trades on the OTCQX Market instead of a national securities exchange, which may make it more difficult for stockholders to sell their shares.

•Our common stock may not be eligible for listing or quotation on any securities exchange.

•The designation of our common stock as a “penny stock” would limit the liquidity of our common stock.

•Sales of substantial amounts of our common stock in the public markets, or the perception that such sales might occur, could cause the market price of our common stock to decline significantly, even if our business is doing well.

•We may be subject to certain liquidated damages pursuant to the registration rights agreement we entered into with certain holders of our securities.

•Our principal stockholders and management have substantial control over us and could delay or prevent a change in corporate control.

•Anti-takeover provisions in our charter documents could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our management.

•the total addressable market and growth rates of the markets in which we compete;

•the competitive landscape of our industry;

•the impact of “controlled company” exemptions that may be available to us in the future under Nasdaq or NYSE listing standards and our use of the applicable phase-in periods; and

•the impact of government regulation and developments relating to us, our competitors or our industry.

We caution you that the foregoing list may not contain all of the forward-looking statements made in this Report.    

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this Report primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, results of operations, and prospects. The outcome of the events described in these forward-looking statements is subject to significant risks, uncertainties, and other factors, including those described in the section titled “Risk Factors” and elsewhere in this Report. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Report. We cannot assure you that the results, events, and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events, or circumstances could differ materially from those described in the forward-looking statements.

Neither we nor any other person assumes responsibility for the accuracy and completeness of any of these forward-looking statements. Moreover, the forward-looking statements made in this Report relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this Report to reflect events or circumstances after the date of this Report or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions, or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures, or investments we may make.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

Parent’s wholly owned-subsidiary, Transphorm Technology, Inc. (“Transphorm Technology”), was incorporated in the State of Delaware on February 22, 2007. Throughout these notes, “the Company,” “Transphorm,” “we,” “us” and “our” refer to Parent and its direct and indirect wholly-owned subsidiaries. Transphorm Technology and its subsidiaries hold all material assets and conduct all business activities and operations of the Company. Transphorm Technology’s activities to date have been primarily performing research and development, establishing manufacturing infrastructure, market sampling, product launch, hiring personnel, and raising capital to support and expand these activities. Transphorm Japan, Inc. was established in Japan in February 2014 to secure Transphorm’s production capacity and establish a direct presence in Asian markets. Transphorm Aizu, Inc. was established in Japan to manage the financial transactions around Aizu Fujitsu Semiconductor Wafer Solution Limited, Transphorm’s non-controlling joint venture wafer fabrication facility located in Aizu Wakamatsu, Japan (“Aizu”). Transphorm Japan Epi, Inc. was established in Japan in 2019 to enable the operational capacity of the reactors held in Aizu.

In management’s opinion, the accompanying unaudited condensed consolidated financial statements of Transphorm reflect all adjustments of a normal and recurring nature that are necessary for a fair presentation of the results for the interim period ended September 30, 2021, but are not necessarily indicative of the results that will be reported for the entire year or any other interim period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with Accounting Principles Generally Accepted in the United States of America (“GAAP”) have been condensed or omitted. The aforementioned unaudited condensed consolidated financial statements are prepared in conformity with GAAP and in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. The interim information should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Transition Report on Form 10-K for the transition period from January 1, 2021 to March 31, 2021. The consolidated balance sheet as of March 31, 2021 is derived from those audited financial statements.

Change in Fiscal Year End

On April 20, 2021, we changed our fiscal year from the period beginning on January 1 and ending on December 31 to the period beginning on April 1 and ending on March 31 of each year, effective immediately. Accordingly, we filed a Transition Report on Form 10-K to include audited consolidated financial information for the transition period from January 1, 2021 through March 31, 2021.

Reverse Merger

On February 12, 2020, our wholly-owned subsidiary, Peninsula Acquisition Sub, Inc., a corporation formed in the State of Delaware (“Acquisition Sub”), merged with and into Transphorm Technology (formerly known as Transphorm, Inc.), the corporate existence of Acquisition Sub ceased, and Transphorm Technology became our wholly-owned subsidiary (such transaction, the “Merger”). As a result of the Merger, we acquired the business of Transphorm Technology. The Merger was effective as of February 12, 2020, upon the filing of a certificate of merger with the Secretary of State of the State of Delaware. Immediately after completion of the Merger, we adopted Transphorm Technology’s former company name, “Transphorm, Inc.”, as our company name.

The Merger was treated as a recapitalization and reverse acquisition for financial reporting purposes, and Transphorm Technology is considered the acquirer for accounting purposes.

As a result of the Merger and the change in our business and operations, a discussion of the past financial results of our predecessor, Peninsula Acquisition Corporation, is not pertinent, and under applicable accounting

16

principles, the historical financial results of Transphorm Technology, the accounting acquirer, prior to the Merger are considered our historical financial results.

At the effective time of the Merger, (i) each share of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger was converted into the right to receive (a) 0.08289152527 shares of our common stock (in the case of shares held by accredited investors) or (b) $4.00 multiplied by 0.08289152527 (in the case of shares held by unaccredited investors), with the actual number of shares of our common stock issued to the former holders of Transphorm Technology’s common stock equal to 4,171,571, (ii) 51,680,254 shares of Transphorm Technology’s Series 1 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 12,433,953 shares of our common stock, (iii) 38,760,190 shares of Transphorm Technology’s Series 2 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 7,499,996 shares of our common stock, and (iv) 31,850,304 shares of Transphorm Technology’s Series 3 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 4,000,000 shares of our common stock. As a result, 28,105,520 shares of our common stock were issued to the former holders of Transphorm Technology’s issued and outstanding capital stock after adjustments due to rounding for fractional shares. Immediately prior to the effective time of the Merger, an aggregate of 682,699 shares of our common stock, owned by the stockholders of Peninsula Acquisition Corporation prior to the Merger, were forfeited and cancelled.

In addition, pursuant to the Merger Agreement, (i) options to purchase 29,703,285 shares of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger under Transphorm Technology’s 2007 Stock Plan (the “2007 Plan”) and 2015 Equity Incentive Plan (the “2015 Plan”) were assumed and converted into options to purchase 2,461,923 shares of our common stock, (ii) warrants to purchase 186,535 shares of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger were assumed, amended and converted into warrants to purchase 15,461 shares of our common stock, and (iii) Transphorm Technology’s outstanding convertible promissory note was amended to be convertible at the option of the holder, into shares of our common stock at a conversion price of $5.12 per share. As of September 30, 2021, there was $15.0 million of principal and $597 thousand of accrued and unpaid interest outstanding on the convertible promissory note.

All per share and share amounts for all periods presented have been retroactively adjusted to reflect the effect of the Merger.

Liquidity and Capital Resources

The Company’s ability to sustain operations is dependent mainly on its ability to successfully market and sell its products and through additional financings until profitability with positive cash flows are achieved. The Company currently incurs and historically has incurred losses from operations and expects to do so in the foreseeable future. The Company has sustained recurring losses and negative cash flows from operations which raised substantial doubt about the Company’s ability to continue as a going concern. During the six months ended September 30, 2021, the Company used $8.6 million of cash in operations. Although we expect to continue to incur losses and negative cash flows from operating activities, during November 2021, we raised $33.0 million from private placements. Consequently, the Company now has sufficient resources to fund its operations for the next twelve months from the date of this filing, and therefore, the substantial doubt about our ability to continue as a going concern has been alleviated. The Company may need to continue to raise additional capital to finance its losses and negative cash flows from operations beyond the next twelve months and may continue to be dependent on additional capital raises.

Impact of COVID-19 on Our Business

The COVID-19 pandemic has adversely disrupted and will further disrupt the operations at certain of our customers, partners, suppliers and other third-party providers for an uncertain period of time, including as a result of travel restrictions, adverse effects on budget planning processes, business deterioration, and/or business shutdowns, all of which has impacted our business and results of operations. Some of our customers have experienced delays in

17

their internal development programs and design cycles with our GaN products due to the effects of COVID-19, which have led to postponements of their orders of our products and postponements of determinations that our products will be used in their designs for new products under development with corresponding delays in their market introduction and our revenues. The future impact of COVID-19 cannot be predicted with certainty and may make it more difficult or preclude us from raising additional capital, increase our costs of capital and otherwise adversely affect our business, results of operations, financial condition and liquidity.

Significant Accounting Policies

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Parent and its wholly-owned subsidiaries, Transphorm Technology, Transphorm Japan, Inc., Transphorm Japan Epi, Inc. and Transphorm Aizu, Inc. Upon consolidation, all significant intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management bases its estimates and assumptions on historical experience, knowledge of current conditions, and its belief of what could occur in the future, given available information. Actual results could differ from those estimates, and such differences could be material to the consolidated financial statements. Estimates are used for, but not limited to, the determinations of fair value of stock awards and promissory notes, accrual of liabilities, revenue recognition, inventory reserve, and useful lives for property and equipment.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly-liquid investments with original maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist principally of bank deposits and money market funds. Restricted cash of $575 thousand consists of $500 thousand of cash in current asset and $75 thousand of long-term deposit in other assets as of September 30, 2021. Restricted cash as of March 31, 2021 includes $75 thousand of long-term deposit in other assets.

Foreign Currency Risk

The Company is exposed to foreign currency risk due to its operations in Japan (Yen). Assets and liabilities of the operations are re-measured into U.S. currency at exchange rates in effect at the balance sheet dates through the consolidated statements of comprehensive income. Gains or losses resulting from foreign currency transactions are re-measured using the rates on the dates on which those elements are recognized during the period and are included in other income or expense in the consolidated statements of operations. As of September 30, 2021 and March 31, 2021, the Company had foreign cash and cash equivalents of $60 thousand and $444 thousand, respectively, which represented 2.4 percent and 4.7 percent, respectively, of total cash and cash equivalents.

Concentrations of Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company is exposed to credit risk in the event of default by the financial institution holding its cash. The Company’s investment policy restricts investments to high-quality investments and limits the amounts invested with any one issuer, industry or geographic area. Risks associated with cash holdings in excess of insured limits are mitigated by banking with high-quality institutions. To date, the Company has not experienced any significant losses on its cash and cash equivalents. The Company periodically evaluates the relative credit standing of these financial institutions.

18

The Company is subject to risks common in the power conversion components industry, including, but not limited to, technological obsolescence, dependence on key personnel, market acceptance of its products, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed.

Comprehensive Loss

Comprehensive loss is comprised of net loss and other comprehensive income (loss). Other comprehensive income (loss) includes the impact of foreign currency translation adjustments.

Accounts Receivable

Accounts receivable are analyzed and allowances for uncollectible accounts are recorded, as required. Provisions for uncollectible accounts, if any, are recorded as bad debt expense and included in general and administrative expenses in the accompanying consolidated statements of operations. The process for determining the appropriate level of allowances for doubtful accounts involves judgment, and the Company considers such factors as the age of the underlying receivables, historical and projected collection trends, the composition of outstanding receivables, current economic conditions and regulatory changes. An account is fully reserved when reasonable collection efforts have been unsuccessful and it is probable that the receivable will not be recovered. Provision for doubtful accounts amounted to $0 and $86 thousand for the three months ended September 30, 2021 and 2020, respectively. Provision for doubtful accounts amounted to $0 and $146 thousand for the six months ended September 30, 2021 and 2020, respectively.

Inventory

Inventory is stated at the lower of cost (first-in, first-out method) or net realizable value. The Company periodically reviews the value of items in inventory and records write-downs or write-offs based on its assessment of slow moving or obsolete inventory. The Company maintains an inventory reserve for obsolete inventory and generally makes inventory value adjustments against the inventory reserve.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is determined using the straight-line method over the estimated useful lives of the respective assets, generally ranging from three to seven years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the related lease term. Depreciation for equipment commences once it is placed in service, and depreciation for buildings and leasehold improvements commences once they are ready for their intended use. The Company expenses maintenance and repair costs that do not extend the life of the asset as they are incurred.

The Company evaluates the carrying amount of its property and equipment whenever events or changes in circumstances indicate that the assets may not be recoverable. An impairment loss would be recognized when estimated future cash flows expected to result from the use of an asset or asset group and its eventual disposition are less than the carrying amount of the asset or asset group. To date, there have been no such impairment losses.

Goodwill

Goodwill arose for the acquisition of a business in February 2014 based in Japan and was accounted for as the purchase of a business. Goodwill generated from business combinations and deemed to have indefinite lives are not subject to amortization and instead are tested for impairment at least annually in December unless certain events occur or circumstances change. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. We test for goodwill impairment annually or earlier if events or changes in circumstances indicate goodwill might possibly be impaired. Impairment exists when the carrying value of the goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to

19

that excess as a charge to operations in the unaudited condensed consolidated statements of operations. For the three and six months ended September 30, 2021 and 2020, no impairment charge was recorded related to goodwill.

Intangible Assets

Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives, which generally range from three to ten years. Each reporting period, the Company evaluates the estimated remaining useful lives of intangible assets and whether events or changes in circumstances warrant a revision to the remaining periods of amortization.

If it is determined that the carrying values might not be recoverable based upon the existence of one or more indicators of impairment, the Company performs a test for recoverability using various methodologies, such as the income approach or cost approach, to determine the fair value of intangible assets depending upon the nature of the assets. If assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds their respective fair values. For the three and six months ended September 30, 2021 and 2020, no impairment charges were recorded related to intangible assets.

Revenue Recognition

The Company derives its revenues from sales of high-powered GaN-based products manufactured utilizing the Company’s proprietary and patented epiwafer technology and wafer fabrication and other assembly processes, sales of GaN epiwafers for the radio frequency (“RF”) and power markets, and sales of licenses to use such patented proprietary technology, as well as enabling EPI wafer growth services and products to our strategic partners. Revenues are recognized when control of these products or licenses are transferred to the Company’s customers in an amount that reflects the consideration it expects to be entitled to in exchange for those products and licenses. Sales and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. The Company does not have any significant financing components associated with its revenue contracts, as payment is received at or shortly after the point of sale.

Disaggregation of Revenue from Contracts with Customers

Revenue consists of licensing revenue, government contract revenue from our contract with the U.S. Navy and product sales, with applicable performance obligations satisfied at a point in time. Products are sold to distributors and end-users in various sectors such as, but not limited to, the automotive, gaming, industrial, IT, and consumer products industries.

As part of the multi-element commercial arrangement executed with Nexperia on April 4, 2018 (see Note 2 - Nexperia Arrangement), the Company agreed to grant Nexperia the perpetual exclusive right to use the Company’s existing Gen-3 manufacturing process technology. License fees are received upon satisfaction of contractual milestones and recognized upon delivery of the perpetual license or transferred technology without any remaining performance obligations. The Company recognized $8.0 million of licensing revenue for the three and six months ended September 30, 2021, and $0 and $5.0 million of licensing revenue for the three and six months ended September 30, 2020, respectively.

In December 2020, we entered into a cooperation and development agreement with Yaskawa Electric Corporation (“Yaskawa”), pursuant to which Yaskawa agreed to provide $4.0 million over approximately three years to fund development activities related to industrial power conversion applications, with an initial focus on servo motor drive applications. Yaskawa provided payments of $1.0 million and $750 thousand of this $4.0 million commitment in December 2020 and July 2021, respectively. The Company evaluated and concluded that the deliverables are the same and nature of the services to be provided to Yaskawa will be consistent over the period of approximately three years. Accordingly, with respect to the $1.0 million payment, the Company recognized $333 thousand as revenue in each of the three months ended December 31, 2020, March 31, 2021 and June 30, 2021

20

and, with respect to the $750 thousand payment, the Company recognized $375 thousand as revenue for the three months ended September 30, 2021.

Government contract revenues are principally generated under research and development contracts. Contract revenues are derived primarily from research contracts with agencies of the U.S. government. We believe credit risk related to accounts receivable arising from such contracts is minimal. These contracts may include cost-plus fixed fee and fixed price terms. All payments to us for work performed on contracts with agencies of the U.S. government are subject to adjustment upon audit by the Defense Contract Audit Agency. The Company received new government authorized rates for billing purposes which allowed for retroactive application since inception. The cumulative impact of this rate change as of September 30, 2021 was $423 thousand, of which $(83) thousand and $505 thousand were recorded in the three months ended March 31, 2021 and September 30, 2020, respectively. The Company will use the new approved rates on a go-forward basis.

Performance Obligations

For performance obligations related to the sale of products, control transfers to the customer at a point in time. The Company’s principal terms of sale are free on board shipping or destination and the Company transfers control and records revenue for product sales upon shipment or delivery to the customer, respectively. For performance obligations related to the licensing of patented technology in perpetuity, control also transfers to the customer at a point in time. The Company transfers control and records revenue for licensing fees once the Company has (i) provided or otherwise makes available the patented technology to the customer and (ii) the customer is able to use and benefit from the patented technology.

Variable Consideration

The nature of the Company’s arrangement with Nexperia gives rise to variable consideration in the form of milestone and royalty payments. The royalties qualify for the sales and usage-based royalty exception, as the license of intellectual property is the predominant item to which the royalty relates and are recognized upon the subsequent sale occurring. The variable amounts are received upon satisfaction of contractually agreed upon development targets and sales volume.

Research and Development

The Company is a party to research grant contracts with the U.S. government for which the Company is reimbursed for specified costs incurred for its research projects. These projects include energy saving initiatives for which the U.S. government offers reimbursement funds. Such reimbursements are recorded as an offset to research and development expenses when the related qualified research and development expenses are incurred. Reimbursable costs are recognized in the same period the costs are incurred up to the limit of approved funding amounts on qualified expenses. Grant reimbursement of $45 thousand and $81 thousand was recorded as an offset to research and development expense for the three months ended September 30, 2021 and 2020, respectively. Grant reimbursement of $72 thousand and $307 thousand was recorded as an offset to research and development expense for the six months ended September 30, 2021 and 2020, respectively.

Stock-Based Compensation

All share-based payments, including grants of stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), are measured at the fair value of the share-based awards on the grant date and recognized over their respective vesting periods, which is generally one to four years. The estimated fair value of stock options at the grant date is determined using the Black-Scholes-Merton pricing model. The RSAs and RSUs are measured using the estimated fair value of the stock price, which, due to limited trading history, is based on recent equity sales. The Company recognizes the fair value of share-based payments as compensation expense for all expected-to-vest stock-based awards over the vesting period of the award using the straight-line attribution or graded vesting method provided that the amount of compensation cost recognized at any date is no less than the portion of the grant-date fair value of the award that is vested at that date.

21

The Black-Scholes-Merton option pricing model requires inputs such as the fair value of common stock on date of grant, expected term, expected volatility, dividend yield, and risk-free interest rate. Further, the forfeiture rate also affects the amount of aggregate compensation expense. These inputs are subjective and generally require significant analysis and judgment to develop. Volatility data is obtained from a study of publicly traded industry peer companies. The forfeiture rate is derived primarily from the Company’s historical data, and the risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues commensurate with the expected term. Management generally uses the simplified method to calculate the expected term for employee grants as the Company has limited historical exercise data or alternative information to reasonably estimate an expected term assumption. The simplified method assumes that all options will be exercised midway between the weighted average vesting date and the contractual term of the option.

Stock-based compensation expense recognized in the Company’s unaudited condensed consolidated financial statements is based on awards that are expected to vest. These expense amounts have been reduced by using an estimated forfeiture rate. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company evaluates the assumptions used to estimate forfeitures annually in connection with the recognition of stock-based compensation expense.

Income (Loss) Per Share

Basic income (loss) per share is calculated by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is calculated by dividing the net loss attributable to common stockholders by the sum of the weighted average number of common shares outstanding plus potential dilutive common shares outstanding during the period. Potential dilutive securities, comprised of stock warrants, restricted stock units and stock options, are not reflected in diluted income (loss) per share because such shares are anti–dilutive. Dilutive impact of potential common shares resulting from common stock equivalents is determined by applying the treasury stock method.

For the three months ended September 30, 2021, there were 2,548,731 shares, consisting of 2,330,316 stock options and 218,415 stock warrants, that were not included in the computation of diluted income per share because their effect would be anti-dilutive. For the six months ended September 30, 2021, there were 3,826,583 shares, consisting of 2,506,531 stock options, 951,637 restricted stock units and 368,415 stock warrants, that were not included in the computation of diluted loss per share because their effect would be anti-dilutive. For the three and six months ended September 30, 2020, there were 3,155,064 shares, consisting of 2,327,423 stock options, 812,180 restricted stock units and 15,461 stock warrants, that were not included in the computation of diluted loss per share because their effect would be anti-dilutive.

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The carrying values of the Company’s financial instruments such as cash equivalents, accounts receivable, revolving credit facility, accounts payable and accrued liabilities approximate fair values due to the short-term nature of these items. The Company has elected the fair value option for its promissory notes.

Income Taxes

The Company accounts for income taxes in accordance with Accounting Standards Codification (“ASC”) 740, Income Taxes (“ASC 740”). ASC 740 prescribes the use of the liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted statutory tax rates in effect at the balance sheet date. The Company records a valuation allowance to reduce its deferred tax assets when uncertainty regarding their realizability exists.

22

Equity Method Investments

The Company uses the equity method to account for investments in entities that it does not control, but in which it has the ability to exercise significant influence over operating and financial policies. The Company's proportionate share of the net income or loss of these companies is included in consolidated net loss. Judgments regarding the level of influence over each equity method investment include consideration of key factors such as the Company's ownership interest, representation on the board of directors or other management body and participation in policy-making decisions.

Segment Reporting

The Company’s operations and its financial performance is evaluated on a consolidated basis by the chief operating decision maker. The Company’s chief operating decision maker is the Parent’s Chief Executive Officer. Accordingly, the Company considers all of its operations to be aggregated in one reportable operating segment. For the three months ended September 30, 2021, total revenue was $11.3 million, of which $11.3 million was from U.S. operations and $27 thousand was from Japan operations. For the three months ended September 30, 2020, total revenue was $1.9 million, of which $1.6 million was from U.S. operations and $289 thousand was from Japan operations. For the six months ended September 30, 2021, total revenue was $14.5 million, of which $14.0 million was from U.S. operations and $498 thousand was from Japan operations. For the six months ended September 30, 2020, total revenue was $8.3 million, of which $7.9 million was from U.S. operations and $319 thousand was from Japan operations.

Recently Issued Accounting Standards under Evaluation

Debt - In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, to address the complexity in accounting for certain financial instruments with characteristics of liabilities and equity. Amongst other provisions, the amendments in this ASU significantly change the guidance on the issuer’s accounting for convertible instruments and the guidance on the derivative scope exception for contracts in an entity’s own equity such that fewer conversion features will require separate recognition, and fewer freestanding instruments, like warrants, will require liability treatment. Refer to our white paper, Accounting simplifications for convertible instruments and warrants, for additional information. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Leases - In June 2020, the FASB issued ASU 2020-05, which amends the effective dates of the FASB’s standards on leasing (ASC 842) to give immediate relief to certain entities as a result of the widespread adverse economic effects and business disruptions caused by the COVID-19 pandemic. In February 2016, the FASB issued ASU 2016-02, Leases, which, for operating leases, requires the lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, on its balance sheet. The guidance also requires a lessee to recognize single lease costs, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. The leasing standard’s effective dates were the fiscal year beginning after December 15, 2019 as originally issued (ASU 2016-02) and the fiscal year beginning after December 15, 2020 as amended by ASU 2019-10. As amended by ASU 2020-05, the leasing standard’s effective date is now the fiscal year beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Financial Instruments - FASB ASU 2020-03, Codification Improvements to Financial Instruments, makes clear the determination of the contractual life of a net investment in leases in estimating expected credit losses under ASC 326, Financial Instruments – Credit Losses. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when

23

such losses are recorded. ASU 2016-13 is effective for the Company in 2023. Early adoption is permitted. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Income Tax - In December 2019, the FASB issued ASU 2019-12, which modifies ASC 740 to simplify the accounting for income taxes. The ASU’s amendments are based on changes that were suggested by stakeholders as part of the FASB’s simplification initiative (i.e., the FASB’s effort to reduce the complexity of accounting standards while maintaining or enhancing the helpfulness of information provided to financial statement users). ASU 2019-12 is effective for fiscal years beginning after December 15, 2022. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Note 2 - Nexperia Arrangement

Nexperia Transaction

On April 4, 2018, the Company entered into a multi-element commercial arrangement with Nexperia B.V. (“Nexperia”) to obtain financing in exchange for the sale of equity instruments and performing certain technology and product development activities for Nexperia (collectively, the “Collaboration Arrangement”). Nexperia specializes in designing, manufacturing and selling a broad range of small discrete semiconductor devices that utilize components such as those manufactured by the Company. Financing under the Collaboration Arrangement is comprised of the following elements:

•$16 million Series 3 preferred stock issuance

•$9 million license fee for transfer of the Gen-3 manufacturing process

•$5 million development loan, originally maturing March 31, 2020 and subsequently extended to June 30, 2020 intended to pre-fund the Gen-4 (Tranche A) technology development (the “Tranche A Loan”)

•$10 million development loan maturing March 31, 2021 intended to pre-fund the Gen-5 and 1200V technology development (the “Tranche B Loan”)

•$10 million revolving loan (the “Tranche C Loan”)

The Company has to use the funds to operate the business in a manner consistent with or reasonably related to those business activities as carried out on or prior to April 4, 2018, the effective date of Collaboration Arrangement. In addition to the multiple elements outlined above, the Company and Nexperia entered into a Supply Agreement requiring that the Company be Nexperia’s primary supplier of specified components until June 30, 2020 on a best efforts basis. By entering into this Collaboration Arrangement, Nexperia gained access to technology that allows for production of high power semiconductors for use in electric vehicles.

Further, Nexperia obtained an exclusive license and market access to automotive customers outside of Japan and a sole license (non-exclusive of the Company), as well as market access to customers in other parts of the power market. Nexperia has a lien on certain of the Company’s U.S. patents not relating to metal organic chemical vapor deposition (“MOCVD”) or epiwafer technology, per the agreement.

On March 31, 2019, the Company executed Amendment No. 1 to the Loan and Security Agreement (the ”LSA”), pursuant to which the Tranche B Loan was bifurcated into the following two separate sub-tranches:

•$8 million development loan intended to pre-fund the Gen-5 (Tranche B) technology development (the “Tranche B Loan”)

24

•$2 million development loan intended to pre-fund the 1200V technology development (the “Tranche B-1 Loan” and, together with the Tranche B Loan, the “Tranche B Loans”)

On February 7, 2020, Amendment No. 2 to the LSA was executed to acknowledge the then-pending Merger, reaffirm the terms of the loans and confirm the waiver for the late delivery of the Company’s 2018 audited financial statements. On April 8, 2020, Amendment No. 3 to the LSA was executed to extend the maturity of the Tranche A Loan to April 30, 2020. On April 28, 2020, Amendment No. 4 to the LSA was executed to further extend the maturity of the Tranche A Loan to June 30, 2020. All other terms set forth under the original LSA remained unchanged following the amendments.

The Tranche A and Tranche B Loans represent pre-funding for Gen-4 (Tranche A), Gen-5 (Tranche B), and 1200V (Tranche B-1) technology development for Nexperia. The specific development activities and associated performance milestones are contained within a Statement of Work (“SoW”) between the Company and Nexperia. The SoW may be modified from time to time based upon mutual business interests. This promise to perform the technology development is a good/service provided to a customer in exchange for consideration in the form of the technology development license fees that offset the Tranche A and Tranche B Loans outstanding. The Development Loans are recognized as a liability equal to the cash proceeds received.

In relation to the license fee for the transfer of the Company’s Gen-3 manufacturing process to Nexperia, the Company received $3 million (the first of three tranches) in October 2018, $3 million (the second of three tranches) in April 2019, and $3 million (the third of three tranches) in October 2019. The Company recognized $9.0 million as licensing revenue during 2019 upon the completion of the transfer of the Company’s Gen-3 manufacturing process technology and mutual sign off between Nexperia and the Company.

In January 2019, the Company received the $5 million Tranche A Loan. In June 2020, Nexperia agreed that the $5 million Tranche A Loan was permanently satisfied in full in connection with the Company transferring its Gen-4 technology development to Nexperia, at which point the Company recognized $5 million as licensing revenue. In June and July 2019, the Company received the $8 million Tranche B Loan. In December 2019, the Company received the $2 million Tranche B-1 Loan.

The Company received the full $10 million Tranche C Loan under the credit facility during the year ended December 31, 2018. See Note 6 - Debts.

On March 1, 2021, Amendment No. 5 to the LSA was executed to extend the maturity of the Tranche B loans of $10 million and the Tranche C Loan of $10 million to June 30, 2021 and May 18, 2021, respectively.

On May 18, 2021, Amendment No. 6 to the LSA was executed to (1) extend the maturity date for the Tranche C Loans to the earlier of April 4, 2023 and the occurrence of specified change of control events, (2) add Parent as a guarantor of Transphorm Technology’s obligations under the Loan Agreement, and (3) convert the outstanding $2 million Tranche B-1 Loan into a Tranche C-1 Loan, which Tranche C-1 Loan has the same terms and conditions as the existing Tranche C Loan.

On May 18, 2021, in addition to Amendment No. 6 to the LSA, the Company entered into a series of agreements with Nexperia, as described below.

Strategic Cooperation Agreement

The strategic cooperation agreement serves as a framework agreement that describes the numerous agreements between the parties and provides Nexperia with information rights and inspection rights with respect to the Company’s business.

25

Option Agreement

The option agreement establishes the parameters pursuant to which Nexperia, in certain limited instances, is permitted to exercise an option (the “Option”) to acquire Transphorm Japan Epi, Inc. (“TJE”), a Japanese subsidiary of the Company through which the Company is engaged in the development, manufacturing and sales of gallium nitride (“GaN”) based epitaxial wafer products. In general, the Option is exercisable upon (1) certain acquisitions of securities or assets of the Company or its subsidiaries by a Competitor (as defined in the option agreement) that results in the Company, directly or indirectly, owning less than a majority of TJE, which acquisition is followed by any material breach (that is not cured within a specified time period) by the Company or a subsidiary of its obligations with respect to epiwafer supply to Nexperia under the Company’s amended and restated supply agreement (the “Supply Agreement”) with Nexperia, or (2) the unilateral termination by the Company of the Supply Agreement. The option agreement also establishes the material terms, including price and timing, for the exercise of the Option by Nexperia. The Option terminates (1) if the Option is not exercised by Nexperia prior to the date on which the option agreement terminates, or (2) on the first to occur of (a) the termination of the option agreement upon written agreement of the parties, (b) the mutual termination or expiration of the Supply Agreement, or (c) the first to occur of (i) two years following the date on which the Company notifies Nexperia of epiwafer qualification of a second source and (ii) April 1, 2028.

In connection with the option agreement, the Company has also amended and restated its existing intracompany license agreement with TJE to clarify Nexperia’s rights upon exercise of the Option.

Amended and Restated Development and License Agreement

The Company entered into an amended and restated development and license agreement (the “DLA”) with Nexperia, pursuant to which the Company agreed to develop and transfer to Nexperia certain manufacturing process technologies to enable Nexperia to manufacture GaN-based products at Nexperia’s facilities. These technologies to be transferred included the Company’s Gen-3, Gen-4 (Tranche A), and Gen-5 (Tranche B) process technologies, but do not include the Company’s Epi Process Technology (as defined in the DLA). Nexperia also agreed to provide funding for the development of such technologies in return for limited exclusivities in automotive and other fields. Nexperia’s rights now include sale of products in the automotive field in Japan along with Transphorm’s rights for sale of products in the automotive field in Japan which remain in place. As per the original agreement, after April 2023, Nexperia’s exclusive rights for sale of products in the automotive field outside of Japan terminate. In addition, the parties have clarified the ability of Nexperia’s customers to use products developed by Nexperia through exercise of its rights under this agreement.

Amended and Restated Supply Agreement

The Company entered into the Supply Agreement with Nexperia, which sets forth the terms under which Nexperia may purchase epiwafers and processed wafers from the Company, and the Company may purchase processed wafers from Nexperia. The agreement specifies that Nexperia is the Company’s priority customer with respect to epiwafers manufactured by TJE and, accordingly, has preferred utilization of extra capacity, and further specifies procedures to address expansion of the Company’s epiwafer manufacturing capacity and Nexperia’s obligations with respect thereto. The term of the Supply Agreement was extended until December 31, 2025, with automatic one year renewals thereafter, and the Company may not terminate the Supply Agreement while the Option Agreement is in effect.

On June 30, 2021, Amendment No. 7 to the LSA was executed to extend the maturity of the Tranche B loans of $8 million to July 16, 2021.

On July 16, 2021, Nexperia agreed that the $8 million Tranche B Loan was satisfied in full in connection with the Company transferring its Gen-5 and 1200V technology developments to Nexperia, at which point the Company recognized $8 million as licensing revenue.

Note 3 - Fair Value Measurements

FASB ASC 820, Fair Value Measurements and Disclosures, establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

Level 1 - Unadjusted quoted prices in active markets for identical assets and liabilities.

Level 2 - Inputs (other than quoted prices included within Level 1) that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data of substantially the full term of the related assets or liabilities.

Level 3 - Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Inputs are unobservable for the asset or liability. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following table summarizes the Company’s liabilities measured at fair value as of the dates presented, by level within the fair value hierarchy (in thousands):

	Level 1		Level 2		Level 3
September 30, 2021
Promissory note	$	—	$	—	$	15,597
March 31, 2021
Promissory note	$	—	$	—	$	16,128

The following table includes the changes in fair value of the promissory note which are Level 3 on the fair value hierarchy (in thousands):

April 1, 2021	$	16,128
Interest expense accrued	74
Increase in fair value	(605)
September 30, 2021	$	15,597
April 1, 2020	$	13,885
Interest expense accrued	150
Increase in fair value	2,093
March 31, 2021	$	16,128

The Company recorded interest expense of $36 thousand and $38 thousand for the three months ended September 30, 2021 and 2020, respectively. The Company recorded interest expense of $74 thousand and $75 thousand for the six months ended September 30, 2021 and 2020, respectively. Fair value of promissory note decreased by $1.6 million and increased by $709 thousand for the three months ended September 30, 2021 and 2020, respectively. Fair value of promissory note decreased by $605 thousand and increased by $2.4 million for the six months ended September 30, 2021 and 2020, respectively.

Level 3 borrowings, which consist of a promissory note, are measured and reported at fair value. As conversion of the promissory note was completed on October 4, 2021, at September 30, 2021, as-converted valuation model was used for the promissory note and a Monte Carlo simulation valuation model was used for warrants issued to purchase shares of common stock upon conversion. Assumptions used for the warrants are a three year term, exercise price of $6.00, risk free rate of 0.53% and volatility of 48.0%. See Note 12 - Subsequent Events.

27

A Monte Carlo simulation valuation model was used at March 31, 2021. The models can include assumptions related to the value of the notes that are based on the estimated timing and amounts of future rounds of financing, including the estimated timing of a change in control of the Company, and estimated market interest rates, which represent significant unobservable inputs. Assumptions used are (1) the Company is worth today what it can generate in future cash to the Company, (2) cash received today is more than an equal amount of cash received in the future, and (3) future cash flows can be reasonably estimated. There were no transfers in or out of level 3 fair value instruments.

The following table summarizes assumptions used for fair value of promissory note as of the dates presented:

	September 30, 2021	March 31, 2021
Stock price	$4.75	$3.75
Time	—	1.5 years
Risk-free rate	—	0.12%
Volatility	48.0%	50.6%

Note 4 - Concentration of Credit Risk and Significant Customers

The Company manages its credit risk associated with exposure to distributors and direct customers on outstanding accounts receivable through the application of credit approvals and other monitoring procedures. Credit sales, which are mainly on credit terms of 30 to 60 days, are only made to customers who meet the Company's credit standards, while sales to new customers or customers with low credit ratings are usually made on an advance payment basis. The Company closely monitors the aging of accounts receivable from its distributors and direct customers, and regularly reviews their financial positions, where available.

28

Significant customers are those that represent 10% or more of revenue or accounts receivable and are set forth in the following table:

			Accounts Receivable As of
			September 30, 2021	March 31, 2021
Customer A			12.9%	31.1%
Customer B			31.2%	33.9%

Note 6 - Debts

Development Loans

On April 4, 2018, the Company entered into a Loan and Security Agreement (“LSA”) and Development and License Agreement (“DLA”) with Nexperia. The LSA provided for term loans in an aggregate principal amount of up to $15.0 million, which term loans were available in tranches (Tranche A, Tranche B and Tranche B-1) and subject to the satisfaction of specified conditions. The Tranche A Loan of $5.0 million initially was scheduled to mature on the earlier of the date a specified report is required to be delivered under the DLA or March 31, 2020. On April 8, 2020, the maturity of the Tranche A loan was extended to April 30, 2020 and, on April 28, 2020, the

29

maturity of the Tranche A Loan was further extended to June 30, 2020. On June 29, 2020, the Tranche A Loan of $5.0 million was satisfied in full when the Company transferred its Gen-4 technology development to Nexperia. The Tranche B Loan of $8.0 million and Tranche B-1 Loan of $2.0 million mature on the earlier of the date a specified report is required to be delivered under the DLA or March 31, 2021, subject to extension as provided in the LSA. On March 1, 2021, the maturity of the Tranche B Loan of $8.0 million and Tranche B-1 Loan of $2.0 million was extended to June 30, 2021.

On June 30, 2021, the maturity of the Tranche B Loan was extended to July 16, 2021. On July 16, 2021, the Tranche B Loan of $8.0 million was satisfied in full when the Company transferred its Gen-5 and 1200V technology developments to Nexperia. See Note 2 - Nexperia Arrangement.

As of September 30, 2021, and March 31, 2021, aggregate principal amount of term loans outstanding under the LSA were $0 and $10.0 million, respectively.

Revolving Credit Facility

The LSA also provided a $10.0 million revolving loan (Tranche C Loan) that was scheduled to mature at the earlier of (i) April 3, 2021, and (ii) the date a Change of Control (as defined in the LSA) of the Company occurs. Interest payable by the Company accrues on the outstanding principal amount of the loans during such period at a rate of 6% per annum. The credit facility is secured against certain of our U.S. patents not relating to MOCVD or epiwafer technology. On March 1, 2021, the maturity of the Tranche C Loan of $10.0 million was extended to May 18, 2021. On May 18, 2021, the maturity of the Tranche C Loan was extended to the earlier of April 4, 2023 and the occurrence of specified change of control events, and $2.0 million Tranche B-1 Loan converted into a Tranche C-1 Loan (the “Tranche C Loans” together with the Tranche C Loan) with the same terms and conditions as the existing Tranche C Loan. See Note 2 - Nexperia Arrangement.

The Tranche C Loans are recorded based on principal in the amount of $12.0 million and accrued interest (6% interest per annum). The Company recorded interest expense of $184 thousand and $153 thousand for the three months ended September 30, 2021 and 2020, respectively, and $350 thousand and $305 thousand for the six months ended September 30, 2021 and 2020, respectively. The Company paid interest expense of $166 thousand and $762 thousand for the three months ended September 30, 2021 and 2020, respectively, and $316 thousand and $762 thousand for the six months ended September 30, 2021 and 2020, respectively.

	September 30, 2021		March 31, 2021
Yaskawa Note	$	15,597	$	16,128

Fair value of promissory note decreased $605 thousand and increased $2.4 million for the six months ended September 30, 2021 and 2020, respectively.

30

In October 2017, the Company issued an unsecured subordinated convertible promissory note to Yaskawa (the “Yaskawa Note”) for $15.0 million. The stated interest rate of the Yaskawa Note is 1.0%, and principal plus interest is due on the earlier of September 30, 2022, or the date of the occurrence of an Event of Default, Change of Control or an Initial Public Offering (all terms as defined in the Yaskawa Note). In connection with the Merger, the Yaskawa Note was amended to be convertible at the option of the holder into a maximum of 3,076,171 shares of our common stock at a conversion price of $5.12 per share.

On October 4, 2021, the Company entered into a Note Amendment and Conversion Agreement with Yaskawa to (i) reduce the conversion price of the Yaskawa Note from $5.12 per share to $5.00 per share and (ii) remove the limitation on the maximum number of shares of the Company’s stock that may be issued upon conversion of the Yaskawa Note. Yaskawa simultaneously elected to convert the outstanding principal amount (plus accrued but unpaid interest) under the Yaskawa Note, which as of the effective date of the conversion totaled $15.6 million, into an aggregate of 3,120,000 shares of our common stock. The Company also issued to Yaskawa a warrant to purchase up to 650,000 shares of common stock at an exercise price of $6.00 per share with a term of three years. See Note 12 - Subsequent Events.

In connection with its promissory note obligation, the Company recorded interest expense of $36 thousand and $38 thousand for the three months ended September 30, 2021 and 2020, respectively and $74 thousand and $75 thousand for the six months ended September 30, 2021 and 2020, respectively.

As of September 30, 2021 and March 31, 2021, accrued interest on the promissory note was $597 thousand and $523 thousand, respectively.

In December 2020, we entered into a cooperation and development agreement with Yaskawa, pursuant to which Yaskawa agreed to provide $4.0 million over approximately three years to fund development activities related to industrial power conversion applications, with an initial focus on servo motor drive applications. Yaskawa provided payments of $1.0 million and $750 thousand of this $4.0 million commitment in December 2020 and July 2021, respectively. Accordingly, with respect to the $1.0 million payment, the Company recognized $333 thousand as revenue in each of the three months ended December 31, 2020, March 31, 2021 and June 30, 2021 and, with respect to the $750 thousand payment, the Company recognized $375 thousand as revenue for the three months ended September 30, 2021.

As of September 30, 2021, the scheduled maturity of the Company’s borrowings under the Tranche C Loans and the Yaskawa Note was as follows (in thousands):

Note 7 - Investment in Aizu Fujitsu Semiconductor Wafer Solution Limited (“AFSW”)

Through July 31, 2021, the Company was party to a joint venture agreement (the “JVA”), by and among Aizu Fujitsu Semiconductor Limited, Fujistu Semiconductor Limited (“FSL”), the Company and Transphorm Aizu, Inc. (“Transphorm Aizu”) for the ownership and operations of AFSW. Through July 31, 2021, the Company held a 49% interest in AFSW through Transphorm Aizu, the Company’s wholly-owned subsidiary established in Japan to manage the financial transactions around AFSW. Transphorm Aizu and FSL funded AFSW based on a mutually agreed funding schedule, which was adjusted as agreed upon by both parties during the three months ended September 30, 2021. Any outstanding balances were reviewed upon the conclusion of the JVA effective July 31, 2021 to assess unfunded commitment to joint venture liability. During the three and six months ended September 30, 2021, the Company recognized a $1.5 million gain, in other income, upon termination of the JVA and settlement of its obligation.

31

On April 1, 2020, FSL exercised its put option under the JVA and notified us that FSL intended to exit the joint venture by selling its 51% interest in AFSW to us. In December 2020, the Company entered into a joint venture agreement with JCP Capital Management, LLC (controlling party with 75% ownership) to create GaNovation, a joint venture company in Singapore, to engage in the business of distribution, development and supply of GaN products and, upon approval of the regulatory authorities in Japan, to purchase FSL’s and Transphorm’s interests in AFSW. In July 2021, regulatory authorities in Japan approved GaNovation’s purchase of 100% of the interests in AFSW from Transphorm and FSL. On July 20, 2021, Transphorm Aizu entered into a Share Purchase Agreement (the “Purchase Agreement”) with GaNovation, pursuant to which GaNovation agreed to acquire Transphorm’s 49% interest in AFSW from Transphorm Aizu for 1 Japanese Yen. The closing of the Purchase Agreement occurred on August 1, 2021. Following the closing of the Purchase Agreement and other concurrent transactions between GaNovation and FSL, Transphorm, through GaNovation, holds a 25% interest in AFSW (down from the previous 49%). For at least one year following the closing, we have agreed to use our best efforts to maintain the operations of AFSW.

AFSW manufactures semiconductor products exclusively for its owners under manufacturing agreements at prices estimated to cover the cost of production. AFSW was determined to be a variable interest entity as the equity at risk was not believed to be sufficient. AFSW depends on its owners for any additional cash. The Company extended $3.1 million and $3.8 million to AFSW to fund AFSW’s operations for the six months ended September 30, 2021 and 2020, respectively. The Company’s known maximum exposure to loss approximated the carrying value of its investment balance, which included the financing. Potential future losses could be higher than the carrying amount of the Company’s investment, as we are liable, along with the other owner, for other future operating costs or obligations of AFSW. In addition, because Transphorm is currently committed to purchasing GaN wafers and production-related services from AFSW at pre-agreed pricing based upon the Company’s second generation products, the Company may be required to purchase products at a higher cost for its newer generation products. Investment in AFSW was $89 thousand as of September 30, 2021 and unfunded commitment to AFSW was $1.9 million as of March 31, 2021.

The Company’s investment activities in AFSW for the periods presented are summarized below (in thousands):

As of September 30, 2021, there is no the future minimum rental payments to be received under the noncancelable sublease.

Contingencies

During the ordinary course of business, the Company may become a party to legal proceedings incidental to its business. The Company accrues contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. Legal cost is expensed as incurred. The Company is not aware of any material legal claims or assessments. Although the results of litigation and claims are inherently unpredictable, management believes there was not at least a reasonable possibility that the Company had incurred a material loss with respect to any loss contingencies as of September 30, 2021 and through the issuance of these financial statements.

Indemnification

The Company from time to time enters into types of contracts that contingently require the Company to indemnify parties against third-party claims. These contracts primarily relate to: (1) real estate leases, under which the Company may be required to indemnify property owners for environmental and other liabilities and for other claims arising from the Company’s use of the applicable premises; (2) agreements with the Company’s officers, directors, and employees, under which the Company may be required to indemnify such persons from liabilities arising out of their relationship; (3) indemnifying customers in the event of product failure; and (4) agreements with outside parties that use the Company’s intellectual property, under which the Company may indemnify for copyright or patent infringement related specifically to the use of such intellectual property.

Historically, the Company has not been required to make payments under these obligations, and no liabilities have been recorded for these obligations in the Company’s unaudited condensed consolidated financial statements.

Common Stock

Common stockholders are entitled to dividends, as and when declared by the Company’s Board of Directors, subject to the priority dividend rights of the holders of other classes of stock. There have been no dividends declared to date. The holder of each share of common stock is entitled to one vote.

The Company has reserved shares of common stock for future issuance as of date presented as follows:

	September 30, 2021
Equity incentive plans	7,030,699
Common stock warrants	368,415
Total	7,399,114

Common Stock Warrants

On December 23, 2020, we issued warrants to purchase 150,000 shares of common stock at an exercise price of $3.30 per share. On August 13, 2021, we issued warrants to purchase 209,000 shares of common stock at an exercise price of $6.00 per share. These warrants are exercisable by paying cash or by cashless exercise for unregistered shares of common stock. The exercise price of the warrants is subject to standard antidilutive provision adjustment in the case of stock dividends or other distributions on shares of common stock or any other equity or equity equivalent securities payable in shares of common stock, stock splits, stock combinations, reclassifications or similar events affecting our common stock, and also, subject to limitations, upon any distribution of assets, including cash, stock or other property to our stockholders. The exercise price of the warrants is not subject to “price-based” anti-dilution adjustment. We have determined that these warrants related to issuance of common stock are subject to equity treatment because warrantholders have no right to demand cash settlement and there are no unusual anti-dilution rights.

The following warrants to purchase common stock were outstanding as of September 30, 2021:

Number of Shares	Exercise Price		Expiration Date
6,046	$	34.74	5 years after an initial public offering of the Company
3,369	$	54.41	5 years after an initial public offering of the Company

Note 10 - Stock Based Compensation

The 2020 Equity Incentive Plan (the “2020 Plan”) was approved by Transphorm Technology’s board of directors on February 10, 2020 and Transphorm Technology’s stockholders on February 12, 2020, and became effective on the business day immediately prior to the closing of the Merger. Our stockholders approved the 2020 Plan on February 11, 2020. We assumed the 2020 Plan in connection with the Merger. The 2020 Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), to our employees and our parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance units, and performance shares to our employees, directors, and consultants and our parent and subsidiary corporations’ employees and consultants. As of September 30, 2021, there were 951,637 restricted stock units

outstanding under the 2020 Plan, 2,506,531 stock options outstanding under the 2020 Plan, and 3,572,531 shares available for grant (which includes an automatic increase of 2,026,599 shares on April 1, 2021) under the 2020 Plan.

Subject to the adjustment provisions of the 2020 Plan, and the automatic increase described in the 2020 Plan, the maximum aggregate number of shares of our common stock that may be issued under the 2020 Plan is 5,050,000 shares of our common stock, which includes (i) 2,588,077 shares initially reserved for issuance, plus (ii) any shares of our common stock subject to issued and outstanding awards under the 2007 Plan or 2015 Plan that were assumed in the Merger and that, on or after the closing of the Merger, expire or otherwise terminate without having been exercised or issued in full, are tendered to or withheld by us for payment of an exercise price or for tax withholding obligations, or are forfeited to or repurchased by us due to failure to vest, with the maximum number of shares to be added to the 2020 Plan pursuant to this clause (ii) equal to 2,461,923 shares. Subject to the adjustment provisions of the 2020 Plan, the number of shares of common stock available for issuance under the 2020 Plan will also include an annual increase on the first day of each fiscal year beginning with our 2022 fiscal year and ending on (and including) our 2030 fiscal year, in an amount equal to the least of: 5,000,000 shares of our common stock; five percent (5%) of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year; or such number of shares of our common stock as the administrator of the 2020 Plan may determine.

Stock-based compensation expense is determined based on the fair value of the Company’s common stock as determined by the Board of Directors and assumptions such as volatility, expected term, risk-free interest rates, and other factors. Changes in the deemed fair value of the common stock, the underlying assumptions in the calculations, the number of options granted or the terms of such options, the expected forfeiture rate, the treatment of tax benefits and other changes may result in significant differences in the amounts or timing of the compensation expense recognized. The assumptions and estimates are made as follows:

•Expected Volatility - The Company utilizes the historical volatility of representative public companies to determine its expected volatility, as the trading history of the Company’s common stock is limited.

•Estimated Forfeitures - The Company adopted ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting and has elected to account for forfeitures as they occur and therefore, stock-based compensation expense has been calculated based on actual forfeitures in the statements of operations, rather than our previous approach which was net of estimated forfeitures. The net cumulative effect of this change was not material.

•Expected Dividend Yield - The Company has not issued any common stock dividends; therefore, a dividend yield of zero was used.

•Risk-Free Interest Rate - The Company bases the risk-free interest rate used in the Black-Scholes-Merton option pricing model on the implied yield currently available on United States Treasury zero-coupon issues with an equivalent expected term.

•Expected Term - The expected term of stock options represents the period that the Company’s stock options are expected to be outstanding. The Company generally uses the simplified method to calculate the expected term for employee grants.

The assumptions used to value options granted to employees during the periods presented was as follows:

	Three and Six Months Ended September 30,
	2021	2020
Weighted average expected life (in years)	6.11	—
Risk-free interest rate	1.08%	—
Expected volatility	43.79%	—
Grant date fair market value	$4.50	—
Grant date fair value	$1.94	—
Dividend yield	—%	—

Restricted Stock

Restricted Stock Awards

RSAs are grants of shares of our common stock that vest in accordance with terms and conditions established by the Company’s Board of Directors. Recipients of RSAs generally will have voting and dividend rights with respect to such shares upon grant without regard to vesting, unless the RSA agreement provides otherwise. Shares of restricted stock that do not vest are subject to forfeiture. In September 2020, we granted 123,501 RSAs outside of our 2020 Plan, 98,450 of which were fully vested on the date of grant and the remainder of which vested in January 2021. In December 2020, we granted 12,000 RSAs outside of our 2020 Plan, all of which were fully vested on the date of grant. There were no RSAs outstanding as of March 31, 2021 and no RSA activities during the three and six months ended September 30, 2021.

Restricted Stock Units

RSUs are grants of shares of our common stock that vest in accordance with terms and conditions established by the administrator of the 2020 Plan. Subject to the provisions of the 2020 Plan, the administrator determines the terms and conditions of RSUs, including the vesting criteria. We granted 816,180 RSUs during the three months ended September 30, 2020, 4,000 of which were fully vested on the date of grant. The remainder of the RSUs are scheduled to vest as follows: one third will vest on each of January 1, 2022, January 1, 2023 and July 1, 2023, in each case subject to the RSU holders’ continued status as a service provider to the Company through each vesting date. We granted 137,452 RSUs during the three months ended March 31, 2021, which are scheduled to vest in various periods, beginning immediately and ending on February 2025, in each case subject to the RSU holders’ continued status as a service provider to the Company through each vesting date. We granted 35,000 RSUs during the three months ended September 30, 2021, 25 percent of which are scheduled to vest after one year and the remainder are scheduled to vest each quarter for three years, in each case subject to the RSU holders’ continued status as a service provider to the Company through each vesting date.

Note 12 - Subsequent Events

Promissory Note Amendment and Conversion

On October 4, 2021, the Company entered into a Note Amendment and Conversion Agreement Yaskawa to (i) reduce the conversion price of the Yaskawa Note from $5.12 per share to $5.00 per share and (ii) remove the limitation on the maximum number of shares of common stock that may be issued upon conversion of the Yaskawa Note. Pursuant to the agreement, Yaskawa simultaneously elected to convert the outstanding principal amount (plus accrued but unpaid interest) under the Yaskawa Note, which, as of October 4, 2021, totaled $15.6 million, into an aggregate of 3,120,000 shares of common stock. Upon conversion of the Yaskawa Note, the Company was released from all obligations and liabilities under the Yaskawa Note.

On October 4, 2021, the Company also issued to Yaskawa a warrant to purchase up to 650,000 shares of common stock at an exercise price of $6.00 per share. The warrant has a term of three years (subject to earlier termination as set forth therein), provides for a cashless exercise feature and is immediately exercisable.

Private Placement of Common Stock and Warrants

Between November 5, 2021 and November 9, 2021, the Company entered into a series of securities purchase agreements (each, a “Purchase Agreement”) with accredited investors (the “Purchasers”), including the Company’s largest stockholder, pursuant to which the Company issued and sold to the Purchasers (i) an aggregate of 6,600,000 shares of common stock at a purchase price of $5.00 per share (the “First Closing Shares”) and (ii) warrants to purchase an aggregate of 1,375,001 shares of common stock (the “First Closing Warrants”), for aggregate gross proceeds of $33.0 million (the “Private Placement”). After payment of placement agent cash fees and expenses of the Private Placement, the Company received net proceeds of approximately $32.2 million. The First Closing Warrants have an exercise price of $6.00 per share, provide for a cashless exercise feature, and are exercisable until the third anniversary of the date of issuance.

Pursuant to the Purchase Agreements, during the Second Investment Period (as described below), each Purchaser has the right (but not the obligation) (an “Option”), subject to the satisfaction of customary closing conditions, to purchase and acquire from the Company (i) additional shares of common stock at a purchase price of $5.00 per share (the “Second Closing Shares”) and (ii) additional warrants to purchase shares of common stock (the “Second Closing Warrants” and together with the First Closing Warrants, the “Warrants”). If and when issued, the Second Closing Warrants would have an exercise price of $6.00 per share, provide for a cashless exercise feature, and be exercisable until the third anniversary of the date of issuance of the First Closing Warrants. If the Options are exercised in full, the maximum number of Second Closing Shares and Second Closing Warrants that may be issued by the Company is 3,299,999 shares of common stock and warrants to purchase 687,501 shares of common stock.

As set forth in the Purchase Agreements, the “Second Investment Period” begins on the date of the applicable Purchase Agreement and ends on the earliest to occur of: (i) the third anniversary of the applicable agreement; (ii) a Change in Control (as defined in the Purchase Agreements), provided that the Company has given the Purchaser at least 10 days’ prior written notice of such Change in Control; (iii) the tenth day after disclosure to the Purchaser of a Change in Control, but only if the Company has not given prior written notice of such Change in Control to the Purchaser in accordance with clause (ii); or (iv) the 90th day following the later of (A) the date on which a registration statement registering the resale of the First Closing Shares and the shares of Common Stock issuable upon exercise of the First Closing Warrants is declared effective by the Securities and Exchange Commission, or (B) the date on which the Company’s common stock is first listed on Nasdaq.

Overview

We are a pioneer, and a market and technology leader, in the wide-bandgap GaN power electronics field for high voltage power conversion applications. We deliver high quality and reliable GaN devices with high performance, while providing application design support to a growing customer base. Our GaN devices allow customers to design smaller, lighter and cooler power systems that create increased functional value in end products including smartphone power adapters, smartphone chargers, power supplies for datacenter servers and automotive electric vehicles, among other applications. We deploy our unique vertically integrated innovation model that leverages one of the industry’s most experienced GaN engineering teams (with over 300 years of combined experience) at every development stage: device design, materials growth, device fabrication, packaging, circuits and application support. This approach, backed by one of the GaN power industry’s largest IP portfolios with access to over 1,000 world-wide patents, has yielded the industry’s first automotive-grade AEC-Q101 and JEDEC qualified high voltage GaN FETs. Our innovations are designed to move power electronics beyond the limitations of silicon and provide our customers with the potential to achieve higher efficiency (e.g., titanium-class performance in power supplies), higher power density and, in some designs, an overall lower system cost.

We received our first product order “in volume” (e.g., greater than ten thousand units) for our Gen-2-based TO247 products in January 2018. We introduced our Gen-3 products in June 2018. Also in 2018, we were awarded a contract from the U.S. Navy to become a supplier for GaN epiwafer products for use by the U.S. Department of Defense. In the fourth quarter of 2019, we recognized $9.0 million of licensing revenue through our first outbound licensing deal with Nexperia. In the second quarter of 2020, we recognized $5.0 million of licensing revenue from Nexperia related to Gen-4 technology development.

Since our inception we have devoted substantial resources to the research and development of GaN power devices and the protection and enhancement of our intellectual property and have incurred significant operating losses. We had net income of $6.0 million for the three months ended September 30, 2021 and net loss of $6.7 million for the three months ended September 30, 2020. We had net loss of $1,072 thousand and $9.0 million for the six months ended September 30, 2021 and 2020, respectively. As of September 30, 2021, our accumulated deficit was $169.5 million. Substantially all of our operating losses have resulted from expenses incurred in connection with research and development activities and from general and administrative costs associated with our operations.

To date, our revenue has been significantly lower than our expenses. Our revenue for the three months ended September 30, 2021 was $11.3 million, of which $8.7 million was from related parties. Our revenue for the three months ended September 30, 2020 was $1.9 million, of which $598 thousand was from related parties and $505 thousand was retroactive application since inception due to new government rates during the period. Our revenue for the six months ended September 30, 2021was $14.5 million, of which $9.7 million was from related parties. Our revenue for the six months ended September 30, 2020 was $8.3 million, of which $6.1 million was from related parties. For the three and six months ended September 30, 2021 and 2020, Nexperia and the U.S. government each accounted for more than ten percent of our revenues.

Reverse Merger

On February 12, 2020, our wholly-owned subsidiary, Peninsula Acquisition Sub, Inc., a corporation formed in the State of Delaware (“Acquisition Sub”), merged with and into Transphorm Technology (formerly known as Transphorm, Inc.), the corporate existence of Acquisition Sub ceased, and Transphorm Technology became our wholly-owned subsidiary (such transaction, the “Merger”). As a result of the Merger, we acquired the business of Transphorm Technology. The Merger was effective as of February 12, 2020, upon the filing of a certificate of merger with the Secretary of State of the State of Delaware. Immediately after completion of the Merger, we adopted Transphorm Technology’s former company name, “Transphorm, Inc.”, as our company name.

The Merger was treated as a recapitalization and reverse acquisition for us for financial reporting purposes, and Transphorm Technology is considered the acquirer for accounting purposes.

As a result of the Merger and the change in our business and operations, a discussion of the past financial results of Peninsula Acquisition Corporation is not pertinent, and under applicable accounting principles, the historical financial results of Transphorm Technology, the accounting acquirer, prior to the Merger are considered our historical financial results.

At the effective time of the Merger, (i) each share of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger was converted into the right to receive (a) 0.08289152527 shares of our common stock (in the case of shares held by accredited investors) or (b) $4.00 multiplied by 0.08289152527 (in the case of shares held by unaccredited investors), with the actual number of shares of our common stock issued to the former holders of Transphorm Technology’s common stock equal to 4,171,571, (ii) 51,680,254 shares of Transphorm Technology’s Series 1 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 12,433,953 shares of our common stock, (iii) 38,760,190 shares of Transphorm Technology’s Series 2 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 7,499,996 shares of our common stock, and (iv) 31,850,304 shares of Transphorm Technology’s Series 3 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 4,000,000 shares of our common stock. As a result, 28,105,520 shares of our common stock were issued to the former holders of Transphorm Technology’s issued and outstanding capital stock after adjustments due to rounding for fractional shares. Immediately prior to the effective time of the Merger, an aggregate of 682,699 shares of our common stock, owned by the stockholders of Peninsula Acquisition Corporation prior to the Merger, were forfeited and cancelled.

In addition, (i) options to purchase 29,703,285 shares of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger under Transphorm Technology’s 2007 Stock Plan and 2015 Equity Incentive Plan were assumed and converted into options to purchase 2,461,923 shares of our common stock, (ii) warrants to purchase 186,535 shares of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger were assumed, amended and converted into warrants to purchase 15,461 shares of our common stock, and (iii) Transphorm Technology’s outstanding convertible promissory note was amended to be convertible, at the option of the holder, into shares of our common stock at a conversion price of $5.12 per share. As of September 30, 2021, there was $15.0 million of principal and $597 thousand of accrued and unpaid interest outstanding on the convertible promissory note.    

All per share and share amounts for all periods presented have been retroactively adjusted to reflect the effect of the Merger.

Private Placements

In February 2020, we sold 5,380,000 shares of common stock in a private placement offering at a purchase price of $4.00 per share, with aggregate gross proceeds of $21.5 million (before deducting placement agent fees and other offering expenses, which were an aggregate of $1.8 million).

45

In December 2020, we sold 5,000,000 shares of common stock in a private placement at a purchase price of $3.00 per share, with aggregate gross proceeds of $15.0 million (before deducting placement agent fees, financial advisor fees and other offering expenses, which were an aggregate of $1.4 million excluding warrant cost of $223 thousand).

In March 2021, we sold 250,000 shares of common stock in a private placement at a purchase price of $4.00 per share, with aggregate gross proceeds of $1.0 million (before deducting placement agent fees, financial advisor fees and other offering expenses, which were an aggregate of $50 thousand).

In August 2021, we sold 1,000,000 shares of common stock in a private placement offering at a purchase price of $5.00 per share, with aggregate gross proceeds of $5.0 million (before deducting legal cost of $22 thousand).

Recent Developments

Between November 5, 2021 and November 9, 2021, we entered into a series of securities purchase agreements (each, a “Purchase Agreement”) with accredited investors (the “Purchasers”), including our largest stockholder, pursuant to which we issued and sold to the Purchasers (i) an aggregate of 6,600,000 shares of common stock at a purchase price of $5.00 per share (the “First Closing Shares”) and (ii) warrants to purchase an aggregate of 1,375,001 shares of common stock (the “First Closing Warrants”), for aggregate gross proceeds of $33.0 million (the “Private Placement”). After payment of placement agent cash fees and expenses of the Private Placement, we received net proceeds of approximately $32.2 million. The First Closing Warrants have an exercise price of $6.00 per share, provide for a cashless exercise feature, and are exercisable until the third anniversary of the date of issuance.

Pursuant to the Purchase Agreements, during the Second Investment Period (as described below), each Purchaser has the right (but not the obligation) (an “Option”), subject to the satisfaction of customary closing conditions, to purchase and acquire from us (i) additional shares of common stock at a purchase price of $5.00 per share (the “Second Closing Shares”) and (ii) additional warrants to purchase shares of common stock (the “Second Closing Warrants” and together with the First Closing Warrants, the “Warrants”). If and when issued, the Second Closing Warrants would have an exercise price of $6.00 per share, provide for a cashless exercise feature, and be exercisable until the third anniversary of the date of issuance of the First Closing Warrants. If the Options are exercised in full, the maximum number of Second Closing Shares and Second Closing Warrants that may be issued by us is 3,299,999 shares of common stock and warrants to purchase 687,501 shares of common stock.

As set forth in the Purchase Agreements, the “Second Investment Period” begins on the date of the applicable Purchase Agreement and ends on the earliest to occur of: (i) the third anniversary of the applicable agreement; (ii) a Change in Control (as defined in the Purchase Agreements), provided that we have given the Purchaser at least 10 days’ prior written notice of such Change in Control; (iii) the tenth day after disclosure to the Purchaser of a Change in Control, but only if we have not given prior written notice of such Change in Control to the Purchaser in accordance with clause (ii); or (iv) the 90th day following the later of (A) the date on which a registration statement registering the resale of the First Closing Shares and the shares of Common Stock issuable upon exercise of the First Closing Warrants is declared effective by the Securities and Exchange Commission, or (B) the date on which our common stock is first listed on Nasdaq.

Key Factors Affecting Our Performance

There are a number of industry factors that affect our business which include, among others:

Overall Demand for Products and Applications Using GaN Devices. Our potential for growth depends significantly on the adoption of GaN materials and devices in the power markets and GaN epiwafer material products in the RF markets, the expansion of the use of GaN devices in infrastructure, IT, datacenter, industrial, automotive and consumer applications such as fast charger/adapter and gaming power supplies, and our ability to win new designs for these applications. Demand also fluctuates based on various market cycles, continuously

46

evolving industry supply chains, trade and tariff terms, as well as evolving competitive dynamics in each of the respective markets. These uncertainties make demand difficult to forecast for us and our customers. The COVID-19 pandemic has adversely disrupted and will further disrupt the operations at certain of our customers, partners, suppliers and other third-party providers for an uncertain period of time, including as a result of travel restrictions, adverse effects on budget planning processes, business deterioration, and/or business shutdowns, all of which has impacted our business and results of operations. Some of our customers have experienced delays in their internal development programs and design cycles with our GaN products due to the effects of the COVID-19 pandemic, which have led to postponements of their orders of our products and postponements of determinations that our products will be used in their designs for new products under development with corresponding delays in their market introduction and potentially our revenues. Our billings under our contract with the U.S. Navy have been lower than originally expected as a result of the pandemic.

Intense and Constantly Evolving Competitive Environment. Competition in the industries we serve is intense. Many companies have made significant investments in product development and production equipment. To remain competitive, market participants must continuously increase product performance, reduce costs and develop improved ways to serve their customers. To address these competitive pressures, we have invested in research and development activities to support new product development, lower product costs and deliver higher levels of performance to differentiate our products in the market.

Governmental Trade and Regulatory Conditions. Our potential for growth, as with most multinational companies, depends on a balanced and stable trade, political, economic and regulatory environment among the countries where we do business. Changes in trade policy such as the imposition of tariffs or export bans to specific customers or countries could reduce or limit demand for our products in certain markets.

Technological Innovation and Advancement. Innovations and advancements in materials and power technologies continue to expand the potential commercial application for our products. However, new technologies or standards could emerge or improvements could be made in existing technologies that could reduce or limit the demand for our products in certain markets.

Intellectual Property Issues. We rely on patented and non-patented proprietary information relating to product development, manufacturing capabilities and other core competencies of our business. Protection of intellectual property is critical. Therefore, steps such as additional patent applications, confidentiality and non-disclosure agreements, as well as other security measures are important. While we have a strong patent portfolio comprising access to over 1,000 worldwide patents (directly owned or licensed) and there is no actual or, to our knowledge, threatened litigation against us for patent-related matters, litigation or threatened litigation is a common method to effectively enforce or protect intellectual property rights. Such action may be initiated by or against us and would require significant management time and expenses.    

Components of Results of Operations

Revenue

Our revenue currently consists of (1) licensing revenue, (2) revenue from our contract with the U.S. Navy and (3) revenue from product sales. Products are sold to distributors and end-users in various sectors such as, but not limited to, the automotive, gaming, industrial, IT, and consumer products industries.

Operating Expenses

Cost of Goods Sold. Cost of goods sold consists of (1) direct product costs incurred for the raw materials and manufacturing services for our products, (2) fixed product costs primarily relating to production, manufacturing and personnel and (3) depreciation and amortization expenses consisting primarily of expenses related to our fixed assets together with amortization of our intangible assets. We expect our cost of goods sold attributable to direct product costs to increase proportionately with increases in revenue, and our cost of goods sold attributable to fixed product costs to remain substantially flat or moderately increase in connection with increases in revenue.

47

Research and Development. Research and development expenses consist primarily of compensation and related costs for personnel, including stock-based compensation and employee benefits as well as costs associated with design, fabrication, packaging and testing of GaN devices. In addition, research and development expenses include depreciation expenses related to our fixed assets. We expense research and development expenses as incurred. As we continue to invest in developing our technology for new products, we expect research and development expenses to remain flat or moderately increase in absolute dollars but to decline as a percentage of revenue.

Sales and Marketing. Sales and marketing expenses consist primarily of compensation and related costs for personnel, including stock-based compensation and employee benefits, and associated travel costs. Sales and marketing expenses also include costs associated with our support of business development efforts with distributors in Europe and Asia, and costs related to trade shows and marketing programs. We expense sales and marketing expenses as incurred. We expect sales and marketing expenses to increase in absolute dollars in future periods as we increase our sales and expand our sales force and our marketing organization.

General and Administrative. General and administrative expenses consist primarily of compensation and related costs for personnel, including stock-based compensation, employee benefits and travel. In addition, general and administrative expenses include third-party consulting, legal, audit, accounting services, allocations of overhead costs, such as rent, facilities and information technology, and amortization of our intangible assets. We expect general and administrative expenses to increase in absolute dollars in future periods due to additional legal, accounting, insurance, investor relations and other costs associated with being a public company, as well as other costs associated with growing our business.

Interest Expense

Interest expense consists primarily of interest and amortization of related costs associated with our debts with Nexperia and Yaskawa, respectively.

Equity Loss in Joint Venture

Equity loss in joint venture consists of expenditures to cover the losses associated with our 25% share ownership starting August 2021 and former 49% share ownership of AFSW. The potential magnitude of this loss may increase or decrease in the future based upon changes in our shareholding percentage in AFSW and the level of operating expenses incurred by AFSW.

Changes in Fair Value of Promissory Note

Changes in the fair value of promissory note reflect valuation changes in the notes held by the Company. Offering costs are expensed as incurred.

Other Income, Net

Other income, net of other expenses, consists primarily of income generated from subleasing a portion of our research and development facility located in California.

Tax Expense

Tax expense consists primarily of income taxes in certain foreign and state jurisdictions in which we conduct business.

Loss in joint venture was $2.6 million for the six months ended September 30, 2021 compared with $3.8 million for the same period in 2020.

Changes in fair value of promissory note were a $605 thousand gain and a $2.4 million loss for the six months ended September 30, 2021 and 2020, respectively.

Other income, net of other expenses, increased $944 thousand, or 89.5 percent, to $2.0 million for the six months ended September 30, 2021 from $1.1 million for the same period in 2020, due primarily to recognition of a $1.5 million gain upon termination of the JVA between FSL and Transphorm Aizu.

Net loss decreased $7.9 million, or 88.1 percent, to $1,072 thousand for the six months ended September 30, 2021 from $9.0 million for the same period in 2020. The increase was attributable primarily to a (i) $6.3 million increase in revenue, (ii) $3.0 million in positive change in fair value of promissory note, and (iii) $1.2 million decrease in loss in joint venture, offset by a $3.4 million increase in operating expenses.

Liquidity and Capital Resources

As of September 30, 2021, we had cash on hand of $2.5 million, other current assets of $7.7 million and current liabilities of $21.9 million, resulting in negative working capital of $11.7 million. As of September 30, 2021, the negative working capital included the promissory note of $15.6 million.

The Company’s ability to sustain operations is dependent mainly on its ability to successfully market and sell its products and through additional financings until profitability with positive cash flows are achieved. The Company currently incurs and historically has incurred losses from operations and expects to do so in the foreseeable future. The Company has sustained recurring losses and negative cash flows from operations which raised substantial doubt about the Company’s ability to continue as a going concern. During the six months ended September 30, 2021, the Company used $8.6 million of cash in operations. Although we expect to continue to incur losses and negative cash flows from operating activities, during November 2021, we raised $33.0 million from private placements. Consequently, the Company now has sufficient resources to fund its operations for the next twelve months from the date of this filing, and therefore, the substantial doubt about our ability to continue as a going concern has been alleviated. The Company may need to continue to raise additional capital to finance its losses and negative cash flows from operations beyond the next twelve months and may continue to be dependent on additional capital raises.

Future Funding Requirements

In February 2020, we sold 5,380,000 shares of our common stock at a purchase price of $4.00 per share in a private placement. In December 2020, we sold 5,000,000 shares of our common stock at a purchase price of $3.00 per share in a private placement. In March 2021, we sold 250,000 shares of our common stock at a purchase price of $4.00 per share in a private placement. In August 2021, we sold 1,000,000 shares of our common stock at a purchase price of $5.00 per share in a private placement. In between November 5, 2021 and November 9, 2021, we sold 6,600,000 shares of our common stock at a purchase price of $5.00 per share in private placements. We believe that our existing cash and cash equivalents will be sufficient to fund our current operating plans for at least the next

52

twelve months. We will continue to evaluate our projected expenditures relative to our available cash and evaluate financing alternatives in order to satisfy our working capital and other cash requirements.

Our principal sources of liquidity have been cash generated by issuing new shares and promissory notes and, more recently, cash generated from operations.

On April 4, 2018, we entered into a multi-element commercial arrangement with Nexperia in order to raise an aggregate of $50.0 million in financing with approximately 9.9% equity dilution (on a fully diluted basis) in exchange for performing certain technology and product development activities for Nexperia. The commercial arrangement includes the LSA with Nexperia, which provides for term loans in an aggregate principal amount of up to $15.0 million and an additional $9.0 million loan commitment. During 2018, as a result of the arrangement with Nexperia, we received $29.0 million, consisting of $16.0 million, $10.0 million and $3.0 million from issuing convertible preferred stock, borrowings under a revolving credit facility and recording deferred revenue of license fee, respectively. During 2019, we received the remaining $21.0 million, consisting of $15.0 million from borrowings under the LSA and $6.0 million in licensing revenue. See Note 2 - Nexperia Arrangement to our condensed consolidated financial statements for more information.

Our future capital requirements will depend on many factors including our revenue growth rate, billing frequency, the impact of the COVID-19 pandemic, the timing and extent of spending to support further sales and marketing and research and development efforts, and our obligations in connection with AFSW. The future impact of the COVID-19 pandemic cannot be predicted with certainty and may make it more difficult or preclude us from raising additional capital, increase our costs of capital and otherwise adversely affect our business, results of operations, financial condition and liquidity. We may in the future enter into arrangements to acquire or invest in complementary businesses, services and technologies, including intellectual property rights. We will require additional equity or debt financing, which we may not be able to raise on terms acceptable to us or at all. If we are unable to raise additional capital when required, our business, results of operations and financial condition would be materially and adversely affected, or we may need to cease operations altogether.

Cash Flows

As of September 30, 2021, our cash and cash equivalents were $2.0 million. The following table shows a summary of our cash flows for the periods presented (in thousands):

	Six Months Ended September 30,				Change
	2021		2020
Net cash (used in) provided by:
Operating activities	$	(8,612)	$	(6,542)	$	(2,070)
Investing activities	(3,490)		(3,825)		335
Financing activities	5,134		14		5,120
Decrease in cash and cash equivalents excluding effect of foreign exchange rate changes	$	(6,968)	$	(10,353)	$	3,385

Operating Activities

Net cash used in operating activities was $8.6 million and $6.5 million for the six months ended September 30, 2021 and 2020, respectively. The decrease of $2.1 million was attributable primarily to a $3.0 million increase in non-cash licensing revenue from a related party, a $3.0 million decrease in changes in fair value of promissory note, a $2.4 million decrease in inventory, and a $2.7 million decrease in loss in joint venture, offset primarily by a $7.9 million increase in net loss.

Investing Activities

53

Net cash used in investing activities was $3.5 million and $3.8 million for the six months ended September 30, 2021 and 2020, respectively. The decrease of $335 thousand was attributable primarily to a $698 thousand decrease in investment in joint venture, offset by a $363 thousand increase in purchases of property and equipment.

Financing Activities

Net cash provided by financing activities was $5.1 million and $14 thousand for the six months ended September 30, 2021 and 2020, respectively. Net cash provided by financing activities during the six months ended September 30, 2021 relates to net proceeds of $5.0 million from the sale of our common stock in a private placement.

Nexperia Loan and Security Agreement

On April 4, 2018, we entered into the LSA with Nexperia. The LSA provides for term loans in an aggregate principal amount of up to $15.0 million, which term loans are available in tranches (Tranche A, Tranche B and Tranche B-1) and subject to the satisfaction of specified conditions. As of September 30, 2021 and March 31, 2021, the aggregate principal amount of term loans outstanding under the LSA was $0 and $10.0 million, respectively. The LSA also provides for a $10.0 million Tranche C Loan commitment, which Tranche C Loans may be borrowed, repaid and reborrowed subject to the terms and conditions of the LSA. As of September 30, 2021 and March 31, 2021, the aggregate principal amount of Tranche C Loans outstanding under the LSA was $12.0 million and $10.0 million, respectively. The proceeds of the loans under the LSA may be used as set forth therein for development work related to the DLA, the repayment of specified debt and for general corporate purposes.

The Tranche A Loan was scheduled to mature on the earlier of the date a specified report is required to be delivered under the DLA or March 31, 2020, which was subsequently extended to June 30, 2020. In June 2020, the $5.0 million Tranche A Loan was satisfied in full upon transfer of our Gen-4 technology development to Nexperia, at which point we recognized $5.0 million as licensing revenue. The Tranche B Loan and Tranche B-1 Loan were scheduled to mature on the earlier of the date a specified report is required to be delivered under the DLA or March 31, 2021, which was subsequently extended to July 16, 2021. On May 18, 2021, the Tranche B-1 Loan was converted into a Tranche C-1 Loan, which Tranche C-1 Loan has the same terms and conditions as the existing Tranche C Loan. The Tranche C commitments terminate, and the Tranche C and C-1 Loans mature, on the earlier of April 4, 2023 and the occurrence of specified change of control events. On July 16, 2021, the $8.0 million Tranche B Loan was satisfied in full upon transfer of our Gen-4 and 1200V technology development to Nexperia, at which point we recognized $8.0 million as licensing revenue.

Loans under the LSA bear interest at the rate of 6.0% per annum. Interest is payable quarterly, on the date of any prepayment or repayment and on each maturity date for the loans then maturing. A commitment fee on the unused portion of the Tranche C Loan commitment accrues at the rate of 0.7% per annum and is payable quarterly.

Our obligations under the LSA are secured by a security interest on certain U.S. patents, which patents do not relate to our MOCVD or epiwafer technology.

The LSA contains customary affirmative covenants, including delivery of financial statements, compliance with laws, and maintenance of insurance and properties, and certain negative covenants, including restrictions on liens on the collateral and restrictions on the disposition and licensing of any patent constituting collateral under the LSA. The LSA also contains customary events of default including, among others, payment defaults, breaches of covenants defaults, the occurrence of a material adverse change, bankruptcy and insolvency defaults, cross defaults with certain material indebtedness, judgment defaults, and the occurrence of a change of control. In addition, an event of default will occur if the DLA is terminated under certain circumstances or we fail to timely deliver reports related to statements of work under the DLA. Upon the occurrence and during the continuance an event of default, Nexperia may declare all or a portion of our outstanding obligations to be immediately due and payable and exercise other rights and remedies provided for under the LSA. If specified events of default occur and remain continuing for more than 30 consecutive days, we are required to assign the patents constituting collateral to Nexperia in

54

satisfaction of our obligations under the LSA. During the existence of an event of default, interest on the obligations could be increased to 3.0% above the otherwise applicable interest rate.

Contractual Obligations and Commitments

As of September 30, 2021, there were no material changes to our contractual obligations and commitments, as described in our Transition Report on Form 10-K for the transition period from January 1, 2021 to March 31, 2021, except for a reduction of $8.0 million in our development loans due within one year of March 31, 2021.

Off-Balance Sheet Transactions

We have not entered into any off-balance sheet arrangements and do not have any holdings in variable interest entities.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements and the related notes thereto were prepared in accordance with Accounting Principles Generally Accepted in the United States (“GAAP”). The preparation of these condensed consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. These estimates are developed based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from the estimates made by management. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operation, and cash flows will be affected.

There have been no material changes to our critical accounting policies and estimates during the three months ended September 30, 2021 from those disclosed in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Transition Report on Form10-K for the transition period from January 1, 2021 to March 31, 2021.

JOBS Act Accounting Election

We are an emerging growth company, as defined in the JOBS Act. The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This provision allows an emerging growth company to either early adopt or delay the adoption of some accounting standards until those standards would otherwise apply to private companies. We have elected to use the extended transition period under the JOBS Act until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

As a “smaller reporting company”, we are not required to provide the information required by this Item.

55

Item 4. Controls and Procedures.

Inherent Limitations on Effectiveness of Controls

Our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well-designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

Evaluation of Disclosure Controls and Procedures

Our disclosure controls and procedures are designed to ensure that information we are required to disclose in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance.

Our management, with the participation of our chief executive officer and our chief financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Report. Based on this evaluation, management, including our chief executive officer and our chief financial officer, concluded that as of September 30, 2021, our disclosure controls and procedures were not effective because of material weaknesses in our internal control over financial reporting.

As disclosed in our Transition Report for the transition period from January 1, 2021 to March 31, 2021, during the year ended December 31, 2018, we identified two material weaknesses, one of which relates to the fact that certain members of our finance team and personnel are able to operate across a number of different functions and have user access that gives rise to segregation of duties risks in connection with our information technology infrastructure. The other material weakness relates to lack of review and evidence to support appropriate level of review and oversight procedures, including lack of team members with technical GAAP, accounting and financial reporting, and internal control skills. These material weaknesses have a significant impact on various activity level and financial reporting cycles which could give rise to the risk of material misstatement of the financial statements due to error, use of management estimates, and accuracy of data or information.

Although we have completed all of the corrective actions and procedures as contemplated herein to remediate the previously identified material weaknesses related to information technology general control as of March 31, 2021, the implemented controls need to operate for a period of time before they can be considered fully remediated.

Changes in Internal Control Over Financial Reporting

Except as described above, there was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the period covered by this Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

56

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 1A. Risk Factors.

An investment in our securities is highly speculative and involves a high degree of risk. We face a variety of risks that may affect our operations or financial results and many of those risks are driven by factors that we cannot control or predict. Investors should carefully consider the risks described below and all of the other information set forth in this Report, before deciding to invest in our common stock. If any of the risks described below occur, our business, financial condition, results of operations and prospects could be materially adversely affected. In that case, the market price of our common stock would likely decline and investors could lose all or a part of their investment. Only those investors who can bear the risk of loss of their entire investment should consider an investment in our securities. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our operations.

Risks Related to Our Business and the Industry in Which We Operate

We have a history of losses, anticipate increasing our operating expenses in the future, and may not be able to achieve or maintain profitability. If we cannot achieve or maintain profitability, stockholders could lose all or part of their investment.

Since our inception in 2007, we have generated minimal revenue and substantial net losses as we have devoted our resources to the development of our technology, and our business model has not been proven. As of September 30, 2021, we had an accumulated deficit of $169.5 million. For the six months ended September 30, 2021 and 2020, our net loss was $1,072 thousand and $9.0 million, respectively. We expect our operating expenses to increase in the future as we expand our sales and marketing efforts and continue to invest in our infrastructure and research and development of our technologies. These efforts may be more costly than we expect, and we may not be able to increase our revenue to offset our increased operating expenses or obtain additional contracts from the federal government. Our revenue growth may be slower than anticipated or our revenue may decline for a number of other reasons, including slower growth of, or reduced demand for, GaN power management solutions, increased competition, or any failure to capitalize on growth opportunities. If we are unable to generate sufficient revenue, we may never become profitable or be able to maintain any future profitability. If this were to occur, our stockholders could lose all or part of their investment.

The Company may need to raise capital to finance its losses and negative cash flows from operations beyond the next twelve months and may continue to be dependent on additional capital raises, which may be unavailable on attractive terms, if at all, and could dilute your investment.

The Company currently incurs and historically has incurred losses from operations and expects to do so in the foreseeable future. The Company has sustained recurring losses and negative cash flows from operations which raised substantial doubt about the Company’s ability to continue as a going concern. Our independent registered public accounting firm issued their audit report on the transition period of three months ended March 31, 2021, and the years ended December 31, 2020 and 2019, which included an explanatory paragraph as to our ability to continue as a going concern. During November 2021, the Company we raised $33.0 million from private placements. Consequently, the Company now has sufficient resources to fund its operations for the next twelve months from the date of this filing, and therefore, the substantial doubt about our ability to continue as a going concern has been alleviated. While we believe that our existing cash and cash equivalents will be sufficient to fund our current operating plans for at least the next twelve months, we have based these estimates on assumptions that may prove to

57

be wrong, and we could spend our available financial resources much faster than we currently expect and need to raise additional funds sooner than we anticipate.

For example, we are party to a joint venture agreement with a third party for the ownership and operations of AFSW, a wafer fabrication facility located in Aizu Wakamatsu, Japan. We currently hold a 25% interest in AFSW. For as long as we have had an ownership interest in AFSW, it has operated at a loss. Our share of the operating losses incurred by AFSW over the 12-month periods ended September 30, 2021 and 2020 were approximately $8.1 million and $4.8 million, respectively. We have agreed to use our best efforts to maintain and continue the operations of AFSW until at least August 1, 2022, which will continue to negatively affect our cash flow. In addition, the ongoing COVID-19 pandemic may negatively impact or slow down any efforts by us to secure additional business for AFSW.

We are also party to a loan and security agreement (the “LSA”) with Nexperia B.V. (“Nexperia”), pursuant to which we have outstanding a $12.0 million revolving loan which bears 6% annual interest and matures on the earlier of April 4, 2023 and the occurrence of specified change of control events.

Our ability to continue as a going concern will depend on us being able to raise significant additional capital to fund our operations and achieve our business objectives, as we do not expect to generate material revenue in the short-term. The future impact of the COVID-19 pandemic cannot be predicted with certainty and may make it more difficult or preclude us from raising additional capital, increase our costs of capital and otherwise adversely affect our business, results of operations, financial condition and liquidity. We will be required to engage in equity or debt financings to secure additional funds. If we close one or more additional equity or convertible debt financings, our stockholders may experience significant dilution of their ownership interests, the rights given to new equityholders may be superior to those of our common stockholders and the per share value of our common stock could decline. Furthermore, if we engage in debt financing, the holders of debt would have priority over the holders of our common stock, and we may be required to accept terms that restrict our ability to run our business or incur additional indebtedness. The debt financing could also contain restrictive covenants that may impact how we run our business and could result in the loan being paid back in full immediately if we are in non-compliance. In addition, if we are unable to raise additional capital when needed or on acceptable terms, we may not be able to, among other things:

•continue our business and operations;

•develop or enhance our products;

•continue to expand our sales and marketing and research and development organizations;

•acquire complementary technologies, products or businesses;

•expand operations, in the United States or internationally;

•hire, train and retain employees; or

•respond to competitive pressures or unanticipated working capital requirements.

Our failure to do any of these things could harm our business, financial condition and results of operations or affect our ability to continue as a going concern.

Our quarterly results of operations are likely to vary from period to period, which could cause the market price of our common stock to fluctuate or decline.

Our results of operations have varied from period to period, and we expect that our quarterly results of operations will continue to vary as a result of a number of factors, many of which are outside of our control and may be difficult to predict, including:

58

•our ability to attract new and retain existing customers, including due to our perceived or actual financial condition;

•the budgeting cycles and purchasing practices of customers;

•the timing and length of our sales cycles, including the ability of our customers to design-in successfully with GaN power solutions;

•changes in customer requirements or market needs, including market acceptance of GaN technology;

•the timing and impact of new product introductions by us or our competitors or any other change in the competitive landscape of the semiconductor industry, including consolidation among our customers or competitors;

•deferral of orders from customers in anticipation of new products or product enhancements announced by us or our competitors;

•our ability to execute on our growth strategy and operating plans;

•our ability to successfully expand our business domestically and internationally;

•our ability to successfully compete with other companies in our market;

•changes in our pricing policies or those of our competitors;

•any disruption in, or termination of, our relationship with channel partners;

•insolvency or credit difficulties confronting our customers, affecting their ability to purchase or pay for our products, or confronting our key suppliers, which could disrupt our supply chain;

•the cost and potential outcomes of potential future litigation;

•general economic conditions, both domestic and in our foreign markets; and

•the amount and timing of operating costs and capital expenditures related to the expansion of our business.

Any of the above factors, individually or in the aggregate, may result in significant fluctuations in our quarterly operating results. As a result of this variability, our historical results of operations should not be relied upon as an indication of future performance. Moreover, this variability and unpredictability could result in our failure to follow through on our operating plans or meet the expectations of investors for any period. If we fail to follow through on our operating plans or meet such expectations for these or other reasons, the market price of our common stock could fall substantially.

Our business could be adversely affected by the effects of health epidemics or pandemic, including the ongoing COVID-19 global pandemic, in regions where we or third parties on which we rely have manufacturing or other business operations.

The effects of health epidemics or pandemic could materially affect our operations globally, including at our headquarters in California and at our subsidiaries in Japan. For example, the COVID-19 pandemic has resulted in government authorities implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter-in-place or stay-at-home orders, and business shutdowns. The COVID-19 pandemic continues to impact our business and has adversely disrupted and will further disrupt the operations at certain of our customers, partners, suppliers and other third-party providers for an uncertain period of time, including as a result of

59

travel restrictions, adverse effects on budget planning processes, business deterioration, and/or business shutdowns, all of which has impacted our business and results of operations. Some of our customers have experienced delays in their internal development programs and design cycles with our GaN products due to the effects of the COVID-19 pandemic, which have led to postponements of their orders of our products and postponements of determinations that our products will be used in their designs for new products under development with corresponding delays in their market introduction and our achievement of revenues. Our billings under our contract with the U.S. Navy have been lower than originally expected as a result of the pandemic. The pandemic has also led to delays for certain milestones in our development projects that are due in 2021.

We have taken precautionary measures intended to minimize the risk of the virus to our employees, our customers, and the communities in which we operate. We required our employees to work remotely unless they could not perform their essential functions remotely, and have also suspended all non-essential travel for our employees. While many of our employees are accustomed to working remotely or working with other remote employees, much of our workforce has not historically been remote. Our employees and consultants typically travel frequently to establish and maintain relationships with one another, our customers and prospective customers, partners, and investors. Although we continue to monitor the situation and may adjust our current policies as more information and public health guidance becomes available, temporarily suspending travel and restricting the ability to do business in person has impacted our customer success efforts, sales and marketing efforts, and may challenge our ability to enter into customer contracts or maintain or enter into new partnerships in a timely manner, slow down our recruiting efforts, or create operational or other challenges, any of which could harm our business, financial condition and results of operations. Furthermore, if a natural disaster, power outage, connectivity issue, or other event occurred that impacted our employees’ ability to work remotely, it may be difficult or, in certain cases, not possible, for us to continue our business for a substantial period of time.

There are no comparable recent events which may provide guidance as to the effect of the spread of COVID-19, and, as a result, the ultimate impact of the COVID-19 pandemic or a similar health epidemic is highly uncertain and will depend on developments, including the duration and spread of the virus and its variants, its impact on our employees, customers, partners, suppliers and other third-party providers, and actions that may be taken by governmental authorities. Some of our suppliers of certain materials used in the production of our products are located in areas impacted by the COVID-19 pandemic, which could limit our ability to obtain sufficient materials for our products. Furthermore, the pandemic may negatively impact our ability to secure additional business for AFSW. The pandemic has and will continue to adversely affect global economies and financial markets, resulting in an economic downturn that could affect demand for our products and impact our operating results. Even after the COVID-19 pandemic has subsided, we may continue to experience an adverse impact to our business as a result of the continued global economic impact of the pandemic. Any of the foregoing could significantly harm our business, and we cannot anticipate all of the ways in which health epidemics such as COVID-19 could adversely impact our business.

We may not be able to develop new technologies and products to satisfy changes in customer demand or industry standards, and our competitors could develop products that decrease the demand for our products.

Rapidly changing technologies and industry standards, along with frequent new product introductions, characterize the industries of many of our customers and potential customers. Our financial performance depends, in part, on our ability to design, develop, manufacture, assemble, test, market and support new products and enhancements on a timely and cost-effective basis.

Our products have not been proven commercially on the scale of conventional power semiconductor products. The principal focus of our research and development activities has been to improve processes and support our ongoing development of GaN power management solutions. These projects are subject to various risks and uncertainties we are not able to control, including changes in customer demand or industry standards and the introduction of new or superior technologies by others. Moreover, any failure by us in the future to develop new technologies or timely react to changes in existing technologies could materially delay our development of new products, which could result in product obsolescence, decreased revenues and a loss of our market share to our competitors. In addition, products or technologies developed by others may render our products or technologies

60

obsolete or non-competitive. Further, if our products are not in compliance with prevailing industry standards, such non-compliance could materially and adversely affect our financial condition, cash flows and results of operations.

We must commit resources to development, design and production prior to receipt of purchase commitments and could lose some or all of the associated investment.

Our sales are typically made pursuant to individual purchase orders, rather than pursuant to long-term supply contracts. Many of these purchase orders may be revised or canceled without penalty. As a result, we typically must commit resources to the design, development, and production of products without any advance purchase commitments from customers. Any inability to sell a product after we devote resources to it could materially and adversely affect our financial condition, cash flows and results of operations.

We compete in highly competitive markets, and competitive pressures from existing and new companies may adversely impact our business and operating results.

The markets in which we compete are highly competitive. We expect competition to intensify in the future as existing competitors and new market entrants introduce new products into our markets. This competition could result in increased pricing pressure, reduced profit margins, increased sales and marketing expenses, and the loss of market share, any of which could seriously harm our business, financial condition and results of operations. If we do not keep pace with product and technology advances and otherwise keep our product offerings competitive, there could be a material and adverse effect on our competitive position, revenue and prospects for growth. Many of our existing competitors, such as silicon-based product providers (e.g., ST Microelectronics, ON Semiconductor, and Mitsubishi), silicon carbide-based product providers (e.g., Rohm, United Silicon Carbide and Wolfspeed) and other high-voltage GaN product providers (e.g., Power Integrations, Infineon, GaN Systems, Navitas and Texas Instruments), have, and some of our potential competitors could have, substantial competitive advantages such as:

•greater name recognition, longer operating histories and larger customer bases;

•larger sales and marketing budgets and resources;

•broader distribution and established relationships with channel partners and customers;

•broader and deeper product lines;

•greater customer support resources;

•greater resources to make acquisitions;

•lower labor and research and development costs;

•substantially greater financial and other resources; and

•larger scale manufacturing operations.

In addition, some of our larger competitors have substantially broader product offerings and may be able to leverage their relationships with channel partners and customers based on other products to gain business in a manner that discourages users from purchasing our products, including by selling at zero or negative margins or product bundling. Potential customers may also prefer to purchase from their existing suppliers rather than a new supplier regardless of product performance or features. As a result, even if the features of our products are superior, customers may not purchase our products. In addition, innovative start-up companies, and larger companies that are making significant investments in research and development, may invent similar or superior products and technologies that compete with our products. Our current and potential competitors may also establish cooperative relationships among themselves or with third parties that may further enhance their resources. If we are unable to

61

compete successfully, or if competing successfully requires us to take costly actions in response to the actions of our competitors, our business, financial condition and results of operations could be adversely affected.

We rely on third-party channel partners to sell our products. If our partners fail to perform, our ability to sell our products and services could be limited, and if we fail to optimize our channel partner model going forward, our operating results could be harmed.

A portion of our revenue is generated through sales by our channel partners, which include distributors and resellers. To the extent our channel partners are unsuccessful in selling our products, we are unable to enter into arrangements with, and retain, a sufficient number of effective channel partners in each of the regions in which we sell products or we are unable to keep our channel partners motivated to sell our products, our ability to sell our products and our operating results could be harmed. The termination of our relationship with any significant channel partner may adversely impact our sales and operating results.

We rely on limited sources of wafer fabrication, packaged products fabrication and product testing, the loss of which could delay and limit our product shipments.

Our partly-owned fabrication facility through AFSW currently satisfies all of our GaN fab-wafer requirements (i.e., when a GaN epiwafer undergoes various processes at a wafer fabrication facility). While we believe AFSW has sufficient capacity for our near-term business needs and is reasonably scalable as our demand for throughput increases, any disruption in the AFSW fabrication facilities may severely impact our supply. In the event we are unable to continuously sustain the AFSW fabrication facility, securing supply from another source and adapting our process at such source would lead to a significant set of challenges, additional costs and delays.

We also utilize relatively standard back-side wafer processing services such as wafer-thinning and wafer back-side metalization from foundries in Asia. These suppliers also offer such services to other companies, which may lead to us not having access to adequate capacity for our needs and our customers’ needs. We may have less control over delivery schedules and overall support versus other customers and users of those facilities. If the wafer foundries we use are unable or unwilling to manufacture our products in our required volumes, or at specified times, we may have to identify and qualify acceptable additional or alternative foundries. This qualification process could typically take three to six months and we may not find sufficient capacity in a timely manner or at an acceptable cost to satisfy our production requirements.

We additionally use outsourced assembly and test providers (“OSATs”) for packaging and testing of our products. We utilize multiple OSATs for various package types and a single OSAT for each type of package. These OSATs may take time, or may be unable, to respond if our throughput demands increase, particularly if we expect a rapid increase in production and could harm our ability to meet unexpected rises in demand in an acceptable time frame. If the OSATs we use are unable or unwilling to package and test our products in our required volumes, or at specified times, we may have to identify and qualify acceptable additional or alternative OSATs. This qualification process would typically take three to nine months and we may not find sufficient capacity in a timely manner or at an acceptable cost to satisfy our production requirements.

Some companies that supply products to our customers are similarly dependent on a limited number of suppliers. These other companies’ products may represent important components of power adapters, inverters and other products into which our products are designed. If these companies are unable to produce the volumes demanded by our customers, our customers may be forced to slow down or halt production on the equipment for which our products are designed, which could materially impact our order levels.

Because we depend on third-party manufacturers to build portions of our products, we are susceptible to manufacturing delays and pricing fluctuations that could prevent us from shipping customer orders on time, if at all, or on a cost-effective basis, which may result in the loss of sales, income and customers.

We depend on third-party manufacturers to build several stages of our products. Our reliance on these third-party manufacturers reduces our control over the manufacturing process and exposes us to risks, including

62

reduced control over quality assurance, product costs, and product supply and timing. Any manufacturing disruption by these third-party manufacturers could severely impair our ability to fulfill orders. Our reliance on third-party manufacturers also creates the potential for infringement or misappropriation of our intellectual property. If we are unable to manage our relationships with third-party manufacturers effectively, or if our third-party manufacturers experience delays or disruptions for any reason, increased manufacturing lead-times, capacity constraints or quality control problems in their manufacturing operations, or if they otherwise fail to meet our future requirements for timely delivery, our ability to ship products to our customers would be severely impaired, and our business and results of operations would be seriously harmed.

Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense. As a result, our revenue is difficult to predict and may vary substantially from period to period, which may cause our results of operations to fluctuate significantly.

Our results of operations may fluctuate, in part, because of the resource intensive nature of our sales efforts, the length and variability of our sales cycle and the short-term difficulty in adjusting our operating expenses. To the extent our competitors develop products that our prospective customers view as equivalent or superior to ours, the average duration of our sales cycles may increase, and our sales efforts may be less successful. Because the length of time required to close a sale varies substantially from customer to customer, it is difficult to predict exactly when, or even if, we will make a sale with a potential customer. As a result, individual sales have, in some cases, occurred in quarters subsequent to or in advance of those we anticipated, or have not occurred at all, which makes it difficult for us to forecast our revenue accurately in any quarter. Because a substantial portion of our expenses are relatively fixed in the short term, our results of operations will suffer if our revenue falls below expectations in a particular quarter, which could cause the market price of our common stock to decline.

Our current operations are concentrated in one location and in the event of an earthquake, terrorist attack or other disaster affecting this location or those of our major suppliers, our operations may be interrupted and our business may be harmed.

Our principal executive offices and primary epiwafer operating facilities are situated near Santa Barbara, California, and most of our major suppliers, which are wafer foundries and assembly houses, are located in areas that have been subject to severe earthquakes and are susceptible to other disasters such as tropical storms, typhoons or tsunamis. In the event of a disaster, such as an earthquake and tsunami in Japan, we or one or more of our major suppliers may be temporarily unable to continue operations and may suffer significant property damage. Any interruption in our ability, or that of our major suppliers, to continue operations could delay the development and shipment of our products and have a substantial negative impact on our financial results. As part of our risk management policy, we maintain insurance coverage at levels that we believe are appropriate for our business. However, in the event of an accident or incident at these facilities, we cannot assure you that the amounts or coverage of insurance will be sufficient to satisfy any damages and losses.

We rely on our management team and other key employees and will need additional personnel to grow our business. The loss of one or more key employees or our inability to attract and retain qualified personnel could harm our business.

Our future success is substantially dependent on our ability to attract, retain and motivate the members of our management team and other key employees throughout our organization. The loss of one or more members of our management team or other key employees could materially impact our sales or our research and development programs and materially harm our business, financial condition, results of operations and prospects. We do not maintain key person life insurance policies on any of our management team members or key employees. Competition for highly skilled personnel is intense. We may not be successful in attracting or retaining qualified personnel to fulfill our current or future needs. For positions in our offices near Santa Barbara, California in particular, we may experience challenges hiring new and mid-level employees in part due to the high local housing costs. Our competitors may be successful in recruiting and hiring members of our management team or other key employees, and it may be difficult for us to find suitable replacements on a timely basis, on competitive terms, or at all.

63

If we fail to effectively manage our growth, our business, financial condition and results of operations would be harmed.

We are a development stage company with 104 employees as of September 30, 2021 and are subject to the strains of ongoing development and growth, which has placed significant demands on our management and our operational and financial infrastructure. To manage any growth effectively, we must continue to improve our operational, financial and management systems and controls by, among other things:

•effectively attracting, training and integrating new employees, particularly members of our sales, applications and research and development teams;

•further improving our key business applications, processes and IT infrastructure to support our business needs;

•enhancing our information and communication systems to ensure that our employees and offices around the world are well coordinated and can effectively communicate with each other and our channel partners and customers; and

•appropriately documenting and testing our IT systems and business processes.

These and other improvements in our systems and controls will require significant capital expenditures and the allocation of valuable management and employee resources. If we fail to implement these improvements effectively, our ability to manage growth and ensure ongoing operation of key business systems would be impaired, and our business, financial condition and results of operations would be harmed.

We are subject to a number of risks associated with international sales and operations.

We have small teams that are engaged in marketing, selling and supporting our products internationally. As a result, we must hire and train experienced personnel to staff and manage our foreign operations. To the extent that we experience difficulties in recruiting, training, managing and retaining international employees, particularly managers and other members of our international sales team, we may experience difficulties in sales productivity in, or market penetration of, foreign markets. We also enter into strategic distributor and reseller relationships with companies in certain international markets where we do not have a local presence. If we are not able to maintain successful strategic distributor and reseller relationships with our international channel partners or recruit additional channel partners, our future success in these international markets could be limited.

We are subject to government regulation, including import, export and economic sanctions laws and regulations that may expose us to liability and increase our costs.

Our products and technology are subject to U.S. export controls, including the U.S. Department of Commerce’s Export Administration Regulations and economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls. These regulations may limit the export of our products and technology, and provision of our services outside of the United States, or may require export authorizations, including by license, a license exception, or other appropriate government authorizations and conditions, including annual or semi-annual reporting. Export control and economic sanctions laws may also include prohibitions on the sale or supply of certain of our products to embargoed or sanctioned countries, regions, governments, persons, and entities. In addition, various countries regulate the importation of certain products, through import permitting and licensing requirements, and have enacted laws that could limit our ability to distribute our products. The exportation, re-exportation, and importation of our products and technology and the provision of services, including by our partners, must comply with these laws or else we may be adversely affected, through reputational harm, government investigations, penalties, and a denial or curtailment of our ability to export our products and technology. Complying with export control and sanctions laws may be time-consuming and may result in the delay or loss of sales opportunities. Although we take precautions to prevent our products and technology

64

from being provided in violation of such laws, our products and technology may have previously been, and could in the future be, provided inadvertently in violation of such laws, despite the precautions we take. If we are found to be in violation of U.S. sanctions or export control laws, it could result in substantial fines and penalties for us and for the individuals working for us. Export or import laws or sanctions policies are subject to rapid change and have been the subject of recent U.S. and non-U.S. government actions. Changes in export or import laws or sanctions policies, may adversely impact our operations, delay the introduction and sale of our products in international markets, or, in some cases, prevent the export or import of our products and technology to certain countries, regions, governments, persons, or entities altogether, which could adversely affect our business, financial condition and results of operations.

Our sales to government customers subject us to uncertainties regarding fiscal funding approvals, renegotiations or terminations at the discretion of the government, as well as audits and investigations, which could result in litigation, penalties and sanctions including early termination, suspension and debarment.

Our multi-year contracts signed with agencies and departments of the U.S. government are generally subject to annual fiscal funding approval and may be renegotiated or terminated at the discretion of the government. Termination, renegotiation or the lack of funding approval for a contract could adversely affect our sales, revenue and reputation. Additionally, our government contracts are generally subject to requirements that are not typically present in commercial contracts, such as various Federal Acquisition Regulation or Defense Federal Acquisition Regulation clauses. These clauses place certain requirements upon us such as compliance with equal opportunity employment, safeguarding of contractor information systems, executive compensation restrictions and reporting of certain lobbying activities. Government contracts are also subject to audits and investigations. Failure to meet contractual requirements could result in various civil and criminal actions and penalties, and administrative sanctions, including termination of contracts, refund of a portion of fees received, forfeiture of profits, suspension of payments, fines and suspensions or debarment from doing business with the government, any of which could materially adversely affect our business, financial condition and results of operations.

Failure to comply with anti-bribery, anti-corruption and anti-money laundering laws could subject us to penalties and other adverse consequences.

We are subject to the U.S. Foreign Corrupt Practices Act (“FCPA”) and other anti-corruption, anti-bribery, and anti-money laundering laws in the jurisdictions in which we do business, both domestic and abroad. These laws generally prohibit us and our employees from improperly influencing government officials or commercial parties in order to obtain or retain business, direct business to any person or gain any improper advantage. The FCPA and similar applicable anti-bribery and anti-corruption laws also prohibit our third-party business partners, representatives and agents from engaging in corruption and bribery. We and our third-party business partners, representatives and agents may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We may be held liable for the corrupt or other illegal activities of these third-party business partners and intermediaries, our employees, representatives, contractors, channel partners and agents, even if we do not explicitly authorize such activities. These laws also require that we keep accurate books and records and maintain internal controls and compliance procedures designed to prevent any such actions. Any violation of the FCPA or other applicable anti-bribery, anti-corruption laws and anti-money laundering laws could result in whistleblower complaints, adverse media coverage, investigations, imposition of significant legal fees, loss of export privileges, severe criminal or civil sanctions or suspension or debarment from U.S. government contracts, substantial diversion of management’s attention, drop in stock price or overall adverse consequences to our business, all of which may have an adverse effect on our reputation, business, financial condition, and results of operations.

Our business may be affected by litigation and government investigations.

We may from time to time receive inquiries and subpoenas and other types of information requests from government authorities and others and we may become subject to claims and other actions related to our business activities. While the ultimate outcome of investigations, inquiries, information requests and legal proceedings is difficult to predict, defense of litigation claims can be expensive, time-consuming and distracting, and adverse resolutions or settlements of those matters may result in, among other things, modification of our business practices,

65

costs and significant payments, any of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to Our Intellectual Property

Any failure by us to protect our proprietary technologies or maintain the right to use certain technologies may negatively affect our ability to compete.

To compete effectively, we must protect our intellectual property. We rely on a combination of patents, trademarks, copyrights, trade secret laws, confidentiality procedures and licensing arrangements to protect our intellectual property rights. We hold numerous patents and have a number of pending patent applications. However, our portfolio of patents evolves as new patents are issued and older patents expire and the expiration of patents could have a negative effect on our ability to prevent competitors from duplicating certain or all of our products.

We might not succeed in obtaining patents from any of our pending applications. Even if we are awarded patents, they may not provide any meaningful protection or commercial advantage to us, as they may not be of sufficient scope or strength, or may not be issued in all countries where our products can be sold. In addition, our competitors may be able to design around our patents.

There can be no assurance that an issued patent will remain valid and enforceable in a court of law through the entire patent term. Should the validity of a patent be challenged, the legal process associated with defending the patent can be costly and time consuming. Issued patents can be subject to oppositions, interferences and other third party challenges that can result in the revocation of the patent or limit patent claims such that patent coverage lacks sufficient breadth to protect subject matter that is commercially relevant. Competitors may be able to circumvent our patents. In cases where market ramp of our products may encounter delays it is possible that some patents or licensed patents covering the product has expired or will be in force for only a short period of time following such market ramp. We cannot predict with any certainty if any third party U.S. or foreign patent rights, or other proprietary rights, will be deemed infringed by the use of our technology. Nor can we predict with certainty which, if any, of these rights will or may be asserted against us by third parties.

To protect our product technology, documentation and other proprietary information, we enter into confidentiality agreements with our employees, customers, consultants and strategic partners. We require our employees to acknowledge their obligation to maintain confidentiality with respect to our products. Despite these efforts, we cannot guarantee that these parties will maintain the confidentiality of our proprietary information in the course of future employment or working with other business partners. We develop, manufacture and sell our products in Asia and other countries that may not protect our intellectual property rights to the same extent as the laws of the United States. This makes piracy of our technology and products more likely. Steps we take to protect our proprietary information may not be adequate to prevent theft of our technology. We may not be able to prevent our competitors from independently developing technologies and products that are similar to or better than ours.

Vigorous protection and pursuit of intellectual property rights or positions characterize the semiconductor industry. This often results in expensive and lengthy litigation. We, and our customers or suppliers, may be accused of infringing patents or other intellectual property rights owned by third parties in the future. An adverse result in any litigation against us or a customer or supplier could force us to pay substantial damages, stop manufacturing, using and selling the infringing products, spend significant resources to develop non-infringing technology, discontinue using certain processes or obtain licenses to use the infringing technology. In addition, we may not be able to develop non-infringing technology or find appropriate licenses on reasonable terms or at all.

Patent disputes in the semiconductor industry between industry participants are often settled through cross-licensing arrangements. Our portfolio of patents may not have the breadth to enable us to settle an alleged patent infringement claim through a cross-licensing arrangement, especially for patent disputes brought by non-practicing entities (patent holders who do not manufacture products but only seek to monetize patent rights) that cannot be settled through cross-licensing and cannot be avoided through cross-licensing with industry practitioners. We may therefore be more exposed to third-party claims than some of our larger competitors and customers.

66

Customers may make claims against us in connection with infringement claims made against them that are alleged to relate to our products or components included in our products, even where we obtain the components from a supplier. In such cases, we may incur monetary losses due to cost of defense, settlement or damage award and non-monetary losses as a result of diverting valuable internal resources to litigation support. To the extent that claims against us or our customers relate to third-party intellectual property integrated into our products, there is no assurance that we will be fully or even partially indemnified by our suppliers against any losses.

Furthermore, we may initiate claims or litigation against third parties for infringing our proprietary rights or to establish the validity of our proprietary rights. This could consume significant resources and divert the efforts of our technical and management personnel, regardless of the litigation’s outcome.

If we fail to comply with our obligations under any license, collaboration or other agreements, we may be required to pay damages and could lose certain intellectual property rights.

Our current licenses impose, and any future licenses we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement and other obligations on us. If we breach any of these obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages and the licensor may have the right to terminate the license, which could result in us being unable to develop, manufacture and sell products that are covered by the licensed technology or could enable a competitor to gain access to the licensed technology. Moreover, our licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing or otherwise violating the licensor’s rights in such unlicensed intellectual property. The amount of our future royalty obligations will depend on the technology and intellectual property we use in products that we successfully develop, manufacture and commercialize, if any. Therefore, even if we successfully develop and commercialize products, we may be unable to achieve or maintain profitability.

For example, our cooperation agreement with Nexperia, which is key to our business, contains certain terms that, if triggered, could have a material adverse effect on our business, financial condition, results of operations and prospects. For instance, the LSA contains customary events of default including, among others, payment defaults, breaches of covenants defaults, the occurrence of a material adverse change, bankruptcy and insolvency defaults, cross defaults with certain material indebtedness, judgment defaults, and the occurrence of a change of control. In addition, an event of default will occur if the DLA is terminated under certain circumstances or we fail to timely deliver reports related to statements of work under the DLA. Upon the occurrence and during the continuance an event of default, Nexperia may declare all or a portion of our outstanding obligations to be immediately due and payable and exercise other rights and remedies provided for under the LSA. If specified events of default occur and remain continuing for more than 30 consecutive days, we are required to assign a portion of our patent portfolio constituting collateral to Nexperia in satisfaction of our obligations under the LSA. During the existence of an event of default, interest on the obligations could be increased to 3.0% above the otherwise applicable interest rate. Additionally, pursuant to an intracompany license agreement with our wholly owned subsidiary, Transphorm Japan Epi (“TJE”), if certain events (some of which may be beyond our control) occur, we could be forced to sell TJE at fair market value to a third party that is approved by us and Nexperia. While TJE’s epiwafer capacity currently is not required for production of our products, if such a “forced sale” event were to happen in the future, we could be required to purchase a portion of our epiwafer requirements from the third party that purchases TJE. This could impact our epiwafer costs, reduce any overall profits, or cause us to lose a portion of our capacity, requiring us to generate more epiwafer capacity earlier than planned. This would result in greater capital expenditure than anticipated, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to Our Financial Control Environment

Being a public company can be administratively burdensome and expensive.

67

As a public reporting company, we are subject to the information and reporting requirements of the Securities Act, the Exchange Act and other federal securities laws, rules and regulations related thereto, including compliance with the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), and the Dodd-Frank Wall Street Reform and Consumer Protection Act. In addition, the listing requirements of any national securities exchange or other exchange and other applicable securities rules and regulations impose various requirements on public companies. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Among other things, we are required to:

•maintain and evaluate a system of internal controls over financial reporting in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act and the related rules and regulations of the SEC and the Public Company Accounting Oversight Board;

•maintain policies relating to disclosure controls and procedures;

•prepare and distribute periodic reports in compliance with our obligations under federal securities laws;

•institute a more comprehensive compliance function, including with respect to corporate governance; and

•involve, to a greater degree, our outside legal counsel and accountants in the above activities.

The costs of preparing and filing annual and quarterly reports, proxy statements and other information with the SEC and furnishing audited reports to stockholders is expensive and compliance with these rules and regulations will require us to hire additional financial reporting, internal controls and other finance personnel, and will involve a material increase in regulatory, legal and accounting expenses and the attention of our board of directors and management. In addition, being a public company makes it more expensive for us to obtain director and officer liability insurance. In the future, we may be required to accept reduced coverage or incur substantially higher costs to obtain this coverage. These factors could also make it more difficult for us to attract and retain qualified executives and members of our board of directors.

Any failure to maintain effective internal controls over our financial reporting could materially and adversely affect us.

Section 404 of the Sarbanes-Oxley Act requires us to include in our annual reports on Form 10-K an assessment by management of the effectiveness of our internal controls over financial reporting. However, while we remain an emerging growth company, we will not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm.

To achieve compliance with Section 404 within the prescribed period, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented, and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed time frame or at all, that our internal control over financial reporting is effective as required by Section 404. For example, in connection with the audit of our consolidated financial statements for the three months ended March 31, 2021, and the years ended December 31, 2020 and 2019, we identified certain deficiencies relating to our internal control over financial reporting that constitute material weaknesses under standards established by the Public Company Accounting Oversight Board (the “PCAOB”), and we cannot predict the outcome of our testing in future periods. If we identify additional material weaknesses in the future or are unable to remediate the material weaknesses we currently have, our financial statements may be inaccurate and investors could lose confidence in the reliability of our financial statements, which in turn could negatively affect the market price of our common stock. In addition, if we are not

68

able to continue to meet these requirements, we may not be able to become or remain listed on any national securities exchange or other exchange or quoted on an over-the-counter market.

We have identified material weaknesses in our internal control over financial reporting that, if not properly remediated, could result in material misstatements in our consolidated financial statements in future periods.

We have limited accounting and financial reporting personnel and other resources with which to address our internal controls and related procedures. In connection with the audit of our consolidated financial statements for the year ended December 31, 2018, we identified certain deficiencies relating to our internal control over financial reporting that constitute material weaknesses under standards established by the PCAOB. As of March 31, 2021, those material weaknesses continued to exist. Accordingly, we were not able to assert that our internal control over financial reporting was effective as of March 31, 2021. As of September 30, 2021, there was no change in our internal control over financial reporting. The PCAOB defines a material weakness as a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. A deficiency in internal control exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis. We identified a material weakness related to the fact that certain members of our finance team and personnel are able to operate across a number of different functions and have user access that gives rise to segregation of duties risks in connection with our information technology infrastructure. Access to systems has subsequently been restricted and access is being managed by independent personnel. Users, roles and permission to systems are reviewed and verified for completeness of data. The other material weakness relates to a lack of evidence to support review work and oversight procedures. Formal review processes and meetings are being introduced in addition to the creation of a specific role in the finance team to review documentation and prepare evidence of such review. These material weaknesses have a pervasive impact on various activity level and financial reporting cycles. We will need to take additional measures to fully remediate these deficiencies. The measures we have taken, and expect to take, to improve our internal controls may not be sufficient to (1) address the issue identified, (2) ensure that our internal controls are effective, or (3) ensure that the identified material weaknesses or other material weaknesses will not result in a material misstatement of our annual or interim financial statements. In addition, other material weaknesses may be identified in the future. If we are unable to correct deficiencies in internal controls in a timely manner, our ability to record, process, summarize and report financial information accurately and within the time periods specified in SEC rules and forms will be adversely affected. This failure could negatively affect the market price and trading liquidity of our common stock, cause investors to lose confidence in our reported financial information, subject us to civil and criminal investigations and penalties, and generally materially and adversely impact our business and financial condition.

If our estimates or judgments relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our results of operations could fall below the expectations of investors, resulting in a decline in the market price of our common stock.

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions that affect the amounts reported in our financial statements. Significant assumptions and estimates used in preparing our financial statements include those related to assets, liabilities, revenue, expenses and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets, liabilities, equity, revenue and expenses that are not readily apparent from other sources. Our results of operations may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our results of operations to fall below the expectations of investors, resulting in a decline in the market price of our common stock.

Changes in accounting rules and regulations, or interpretations thereof, could result in unfavorable accounting charges or require us to change our compensation policies.

69

Accounting methods and policies for companies such as ours, including policies governing revenue recognition, leases, research and development and related expenses, and accounting for stock-based compensation, are subject to review, interpretation and guidance from our auditors and relevant accounting authorities, including the SEC. Changes to accounting methods or policies, or interpretations thereof, may require us to reclassify, restate or otherwise change or revise our historical financial statements, including those contained in this Report.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

We have incurred substantial losses during our history, do not expect to become profitable in the near future and may never achieve profitability. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre-change net operating loss carryforwards (“NOLs”), and other pre-change tax attributes (such as research tax credits) to offset its post-change income or taxes may be limited. The Merger, our prior equity offerings and other changes in our stock ownership may have resulted in ownership changes. In addition, we may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which are outside of our control. As a result, if we earn net taxable income, our ability to use our pre-change NOLs to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. For example, California recently passed the 2020 Budget Act, which temporarily suspends the use of NOLs and limits the utilization of the research credit to $5 million annually for 2020, 2021 and 2022.

Risks Related to Ownership of Our Common Stock

We are an “emerging growth company” and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company” as defined in the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including (1) not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, (2) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and (3) exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an emerging growth company until the last day of our fiscal year ending March 31, 2026, although circumstances could cause us to lose that status earlier.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to use the extended transition period under the JOBS Act until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Even after we no longer qualify as an emerging growth company, we may still qualify as a “smaller reporting company” which would allow us to take advantage of many of the same exemptions from disclosure requirements including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation. If we rely on these exemptions, investors may find our common stock less attractive, which could result in a less active trading market, if any, for our common stock and more volatility or a decline in our stock price.

We are a smaller reporting company, and we cannot be certain if the reduced disclosure requirements applicable to smaller reporting companies will make our common stock less attractive to investors.

70

We are currently a “smaller reporting company,” meaning that we are not an investment company, an asset-backed issuer, or a majority-owned subsidiary of a parent company that is not a smaller reporting company and the market value of our stock held by non-affiliates, or our public float, is less than $250 million. In the event our public float increases, we will remain a smaller reporting company if we continue to have annual revenues of less than $100 million during our most recently completed fiscal year and our public float is less than $700 million. If we are still considered a smaller reporting company at such time as we cease being an “emerging growth company,” we will be required to provide additional disclosure in our SEC filings. However, similar to emerging growth companies, smaller reporting companies are able to provide simplified executive compensation disclosures in their filings; are exempt from the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring that independent registered public accounting firms provide an attestation report on the effectiveness of internal control over financial reporting; and have certain other decreased disclosure obligations in their SEC filings, including, among other things, only being required to provide two years of audited financial statements in annual reports. Decreased disclosures in our SEC filings due to our status as a smaller reporting company may make it harder for investors to analyze our results of operations and financial prospects, and may cause some investors not to invest in or hold our stock.

We are not currently subject to compliance with rules requiring the adoption of certain corporate governance measures and, as a result, our stockholders have limited protections against interested director transactions, conflicts of interest and similar matters.

The Sarbanes-Oxley Act, as well as resulting rule changes enacted by the SEC, the New York Stock Exchange and the Nasdaq Stock Market, require the implementation of various measures relating to corporate governance. These measures are designed to enhance the integrity of corporate management and the securities markets and apply to securities which are listed on those exchanges. Because our common stock is not currently listed on a national securities exchange, we are not required to comply with many of the corporate governance provisions and we have not yet adopted certain of these measures. Until we comply with such corporate governance measures, regardless of whether such compliance is required, the absence of such standards of corporate governance may leave our stockholders without protections against interested director transactions, conflicts of interest and similar matters.

We may be a controlled company within the meaning of the Nasdaq and NYSE rules if we eventually list on such exchange, and, as a result, may qualify for and intend to rely on exemptions from certain corporate governance requirements.

As of September 30, 2021, KKR Phorm Investors L.P. (“Phorm”) beneficially owned approximately 50.8% of our outstanding common stock. As a result, we may be a controlled company within the meaning of the Nasdaq or NYSE corporate governance standards, if we eventually list on the applicable exchange. Under Nasdaq rules, for example, a controlled company may elect not to comply with certain corporate governance requirements of the Nasdaq, including the requirements that:

•a majority of the board of directors consist of independent directors;

•the nominating and corporate governance committee be composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities;

•compensation committee be composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and

•there be an annual performance evaluation of the nominating and corporate governance and compensation committees.

If we were to list on Nasdaq in the future and are a controlled company at such time, we intend to utilize these exemptions (or similar exemptions if we were to list on NYSE), including the exemption for a board of directors composed of a majority of independent directors. In addition, we may rely on the phase-in rules of the

71

SEC, Nasdaq or NYSE if we are no longer a controlled company under the applicable listing standard. For example, the phase-in rules for Nasdaq permit us to have a compensation committee that has one member that is independent at the time that we cease to be a controlled company, a majority of members that are independent within 90 days thereafter and all members that are independent within one year thereafter. Accordingly, you may not have the same protections afforded to shareholders of companies that are subject to all of the corporate governance requirements of Nasdaq or NYSE.

In addition, pursuant to the terms of a stockholders agreement with Phorm (the “Phorm Stockholders Agreement”), Phorm has the right to appoint a member to each committee that may be established by our board of directors, appoint the chair of our board of directors, and nominate a majority of our board of directors, in each case subject to a phase-out period based on Phorm’s future share ownership. Phorm may assign these and other governance rights to certain transferees. Accordingly, even if we are no longer a controlled company, holders of our common stock may not have the same protections afforded to stockholders of companies that do not have a stockholders agreement similar to ours.

Our common stock trades on the OTCQX Market instead of a national securities exchange, which may make it more difficult for stockholders to sell their shares.

Our common stock is currently quoted on the OTC Market Group’s OTCQX Market quotation system under the ticker symbol “TGAN.” The OTC Markets are regulated quotation services that display real-time quotes, last sale prices and volume limitations in over-the-counter securities. Trading in shares quoted on the OTCQX is often thin, meaning that the number of persons interested in purchasing stock at or near bid prices at any given time may be relatively small or non-existent, and characterized by volatility in trading prices. This volatility may be caused by a variety of factors, including the lack of readily available price quotations, the absence of consistent administrative supervision of bid and ask quotations, lower trading volume and market conditions. As a result, there may be wide fluctuations in the market price of the shares of our common stock for reasons unrelated to operating performance, and this volatility, when it occurs, may have a negative effect on the market price of our common stock. Moreover, the OTCQX is not a stock exchange, and trading of securities on it is often more sporadic than the trading of securities listed on a national quotation system or stock exchange. Accordingly, our stockholders may not be able to realize a fair price for their shares when they determine to sell them or may have to hold them for a substantial period of time until the market for our common stock improves. In addition, the stock markets in general, including in the industry in which we operate, have experienced extreme volatility, particularly due to the COVID-19 pandemic, that has, in some cases, been unrelated to the operating performance of the issuer. Accordingly, these broad market and industry factors may also seriously harm the market price of our common stock, regardless of our operating performance.

Our common stock may not be eligible for listing or quotation on any securities exchange.

We do not currently meet the initial quantitative listing standards of any national securities exchange and we may never be able to satisfy the listing requirements for our common stock to be listed on a national securities exchange, which is often a more widely-traded and liquid market. Some, but not all, of the factors which may delay or prevent the listing of our common stock on a more widely-traded and liquid market include the following: our stockholders’ equity may be insufficient; the market value of our outstanding securities may be too low; our net income from operations may be too low; our common stock may not be sufficiently widely held; we may not be able to secure market makers for our common stock; and we may fail to meet the rules and requirements mandated by the several exchanges and markets to have our common stock listed. Should we fail to satisfy the initial listing standards of the national exchanges, or our common stock is otherwise rejected for listing, the trading price of our common stock could suffer, the trading market for our common stock may be less liquid and our common stock price may be subject to increased volatility.

The designation of our common stock as a “penny stock” would limit the liquidity of our common stock.

Our common stock may be deemed a “penny stock” (as that term is defined under Rule 3a51-1 of the Exchange Act). Generally, “penny stock” is common stock that is not listed on a securities exchange and trades for

72

less than $5.00 a share. Prices often are not available to buyers and sellers and the market may be very limited. Penny stocks in start-up companies are among the riskiest equity investments. Broker-dealers who sell penny stocks must provide purchasers of these stocks with a standardized risk-disclosure document prepared by the SEC. The document provides information about penny stocks and the nature and level of risks involved in investing in the penny stock market. A broker must also provide purchasers with bid and offer quotations and information regarding broker and salesperson compensation and make a written determination that the penny stock is a suitable investment for the purchaser and obtain the purchaser’s written agreement to the purchase. Many brokers and investors choose not to participate in penny stock transactions, which may result in further liquidity constraints and declines in the trading price of our common stock. Because of the penny stock rules, there may be less trading activity in penny stocks in any market that develops for our common stock in the future and stockholders are likely to have difficulty selling their shares.

Sales of substantial amounts of our common stock in the public markets, or the perception that such sales might occur, could cause the market price of our common stock to decline significantly, even if our business is doing well.

Sales of a substantial number of shares of our common stock into the public market, particularly sales by our directors, executive officers and principal stockholders, or the perception that these sales might occur in large quantities, could cause the market price of our common stock to decline. If our stockholders sell, or the market perceives that our stockholders intend to sell, a substantial amount of our common stock in the public market, the market price of our common stock could decline significantly.

We may be subject to certain liquidated damages pursuant to the registration rights agreement we entered into with certain holders of our securities.

Pursuant to registration statements that were declared effective by the SEC on June 19, 2020 and January 27, 2021 (the “Resale Registration Statements”), we registered an aggregate of 43,512,653 shares of our common stock, which includes shares of common stock reserved for issuance pursuant to certain outstanding warrants and a convertible promissory note, for resale by the stockholders named therein. Pursuant to the registration rights agreements we entered into with certain holders of our securities, subject to certain exceptions, if (i) the Resale Registration Statements cease to remain continuously effective or such holders are otherwise not permitted to utilize the Resale Registration Statements to resell their registrable securities for a period of more than 15 consecutive trading days, or (ii) trading of our common stock is suspended or halted for more than three full, consecutive trading days, we may be subject to certain liquidated damages up to a maximum amount equal to the aggregate purchase price paid by the holders for their registrable securities.

FINRA sales practice requirements may limit a stockholder’s ability to buy and sell our stock.

The Financial Industry Regulatory Authority (“FINRA”) has adopted rules requiring that, in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative or low-priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information. Under interpretations of these rules, FINRA has indicated its belief that there is a high probability that speculative or low-priced securities will not be suitable for at least some customers. If these FINRA requirements are applicable to us or our securities, they may make it more difficult for broker-dealers to recommend that at least some of their customers buy our common stock, which may limit the ability of our stockholders to buy and sell our common stock and could have an adverse effect on the market for and price of our common stock. This could also make it more difficult for us to raise capital.

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

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not currently have and may never obtain research

73

coverage by securities and industry analysts. In addition, because we did not become a reporting company by conducting an underwritten initial public offering of our common stock, and because we are not currently listed on a national securities exchange, security analysts of brokerage firms may not provide coverage of our company. We cannot assure you that brokerage firms will provide analyst coverage of our company in the future, or continue such coverage if started. In addition, investment banks may be less likely to agree to underwrite secondary offerings on our behalf than they might if we became a public reporting company by means of an underwritten initial public offering, because they may be less familiar with our company as a result of more limited coverage by analysts and the media, which could harm our ability to raise additional funding in the future. The failure to receive research coverage or support in the market for our shares will have an adverse effect on our ability to develop a liquid market for our common stock, which will negatively impact the trading price of our common stock.

If any of the analysts who cover us issue an adverse or misleading opinion regarding us or if our operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

Our principal stockholders and management have substantial control over us and could delay or prevent a change in corporate control.

As of September 30, 2021, Phorm, our largest stockholder, beneficially owned approximately 50.8% of our common stock, and our executive officers and directors, together with holders of ten percent or more of our outstanding common stock and their respective affiliates, beneficially owned approximately 54.2% of our common stock. As a result, these stockholders, acting together, or Phorm individually, have the ability to significantly impact the outcome of matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation, or sale of all or substantially all of our assets. In addition, these stockholders, acting together or Phorm individually, have the ability to significantly impact the management and affairs of our company. Under the Phorm Stockholders Agreement, Phorm has the right to nominate (i) a majority of the board so long as it beneficially owns at least 40% of our then-outstanding shares of common stock, (ii) 33% of the directors (rounded up to the nearest whole number) so long as it beneficially owns at least 20% but less than 40% of our then-outstanding shares of common stock, and (iii) 10% of the directors (rounded up to the nearest whole number) so long as it beneficially owns at least 10% but less than 20% of our then-outstanding shares of common stock. Further, pursuant to the Phorm Stockholders Agreement, so long as Phorm beneficially owns 20% or more of the outstanding shares of our common stock, we will take all necessary action to cause a director nominated by Phorm to serve as chair of our board of directors.

The interests of these stockholders may not be the same as or may even conflict with your interests. The concentration of ownership and Phorm’s rights under the Phorm Stockholders Agreement might decrease the market price of our common stock by:

•delaying, deferring, or preventing a change in control of the company, which could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company or our assets and might affect the prevailing market price of our common stock;

•impeding a merger, consolidation, takeover, or other business combination involving us; or

•discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of the company.

The significant concentration of stock ownership may also adversely affect the trading price of our common stock due to investors’ perception that conflicts of interest may exist or arise.

Anti-takeover provisions in our charter documents could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our management.

74

Provisions in our amended and restated certificate of incorporation and in our amended and restated bylaws may delay or prevent an acquisition of us or a change in our management. These provisions include a classified board of directors, a prohibition on actions by written consent of our stockholders from and after the date that Phorm beneficially owns less than a majority of our outstanding shares of common stock, supermajority voting requirements to amend certain provisions of our certificate of incorporation and bylaws from and after the date that Phorm beneficially owns less than a majority of our outstanding shares of common stock, and the ability of our board of directors to issue preferred stock without stockholder approval. Although we believe these provisions collectively will provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our board of directors, they would apply even if the offer may be considered beneficial by some stockholders. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove then-current management by making it more difficult for stockholders to replace members of the board of directors, which is responsible for appointing the members of management. In addition, we have opted out of the provisions of Section 203 of the Delaware General Corporation Law (“DGCL”), which generally prohibit a Delaware corporation from engaging in any of a broad range of business combinations with any interested stockholder for a period of three years following the date on which the stockholder became an interested stockholder. However, our amended and restated certificate of incorporation provides substantially the same limitations as are set forth in Section 203 but also provides that Phorm and its affiliates and any of their direct or indirect transferees and any group as to which such persons are a party do not constitute interested stockholders for purposes of this provision.

Our bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, and also provide that the federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, each of which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our bylaws provide that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, stockholders, officers or other employees to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws or (iv) any action asserting a claim that is governed by the internal affairs doctrine, in each case subject to the Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein and the claim not being one which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery or for which the Court of Chancery does not have subject matter jurisdiction. Furthermore, our bylaws provide that, unless we consent in writing to an alternative forum, the federal district courts of the United States will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act.

Any person purchasing or otherwise acquiring any interest in any shares of our common stock shall be deemed to have notice of and to have consented to these provisions of our bylaws. These choice of forum provisions may limit our stockholders’ ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents even though an action, if successful, might benefit our stockholders. Stockholders who do bring a claim in the Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. The Court of Chancery or a federal district court may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. Alternatively, if a court were to find either of these provisions of our bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could have a material adverse effect on our business, financial condition or results of operations.

We do not intend to pay dividends for the foreseeable future so any returns will be limited to changes in the value of our common stock.

75

We have never declared nor paid cash dividends on our capital stock. We currently intend to retain any future earnings to finance the operation and expansion of our business, and we do not expect to declare or pay any dividends in the foreseeable future. Any future determination about the payment of dividends will be made at the discretion of our board of directors and will depend upon our results of operations, cash flows and financial condition, operating and capital requirements, contractual restrictions, including any loan or debt financing agreements, and such other factors as our board of directors deems relevant. As a result, stockholders must rely on sales of their common stock after price appreciation as the only way to realize any future gains on their investment, which may never occur.

Exhibit 4.1

THIS WARRANT AND THE SECURITIES ISSUABLE UPON THE EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY U.S. STATE SECURITIES LAWS. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF REGULATION S, PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN EACH CASE ONLY IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS.

WARRANT NO. CS2021-2	NUMBER OF SHARES: 209,000
DATE OF ISSUANCE : August 13, 2021	(subject to adjustment hereunder)
EXPIRATION DATE: August 13, 2024

WARRANT TO PURCHASE SHARES

OF COMMON STOCK OF

TRANSPHORM, INC.

This Warrant is issued to SAS Capital Co., Ltd., or its registered assigns (including any successors or assigns, the “Warrantholder”), in connection with that certain Stock Purchase Agreement, dated as of August 13, 2021, by and among Transphorm, Inc., a Delaware corporation (the “Company”), and the Warrantholder (the “Purchase Agreement”).

1.EXERCISE OF WARRANT.

(a)    Number and Exercise Price of Warrant Shares; Expiration Date. Subject to the terms and conditions set forth herein, the Warrantholder is entitled to purchase from the Company up to 209,000 shares of the Company’s common stock, $0.0001 par value per share (the “Common Stock”) (as adjusted from time to time pursuant to the provisions of this Warrant) (the “Warrant Shares”), at a purchase price of $6.00 per share (the “Exercise Price”), on or before 5:00 p.m. New York City time on August 13, 2024 (the “Expiration Date”) (subject to earlier termination of this Warrant as set forth herein).

(b)    Method of Exercise. While this Warrant remains outstanding and exercisable in accordance with Section 1(a) above, the Warrantholder may exercise this Warrant in accordance with Section 6 herein, by either:

(i)    wire transfer to the Company or cashier’s check drawn on a United States bank made payable to the order of the Company, or

(ii)    exercising of the right to credit the Exercise Price against the Fair Market Value (as defined below) of the Warrant Shares on the date of exercise (the “Net Exercise”) pursuant to Section 1(c).

Notwithstanding anything herein to the contrary, the Warrantholder shall not be required to physically surrender this Warrant to the Company until the Warrantholder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Warrantholder shall surrender this Warrant to the Company for cancellation within three trading days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall

1

have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Warrantholder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases.

(c)    Net Exercise. If the Company shall receive written notice from the Warrantholder at the time of exercise of this Warrant that the holder elects to Net Exercise the Warrant, the Company shall deliver to such Warrantholder (without payment by the Warrantholder of any exercise price in cash) that number of Warrant Shares computed using the following formula:

X=	Y (A-B)
	A

Where        

X =	The number of Warrant Shares to be issued to the Warrantholder.
Y =	The number of Warrant Shares purchasable under this Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being cancelled (at the date of such calculation).
A =	The Fair Market Value of one share of Common Stock (at the date of such calculation).
B =	The Exercise Price (as adjusted hereunder to the date of such calculations).

The “Fair Market Value” of one share of Common Stock as of a particular date shall be determined as follows: (i) if traded on a securities exchange, the value shall be deemed to be the average of the closing prices of the Common Stock on such exchange over the thirty (30) day period ending two business days prior to the date of Net Exercise; (ii) if traded over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever is applicable) of the Common Stock over the thirty (30) day period ending two business days prior to the Net Exercise; or (iii) if fair market value cannot be calculated as of such date on either of the foregoing bases, the price determined in good faith by the Company’s Board of Directors.

(d) Deemed Exercise. In the event that immediately prior to the close of business on the Expiration Date, the Fair Market Value of one share of Common Stock (as determined in accordance with Section 1(c) above) is greater than the then applicable Exercise Price, this Warrant shall be deemed to be automatically exercised on a net exercise issue basis pursuant to Section 1(c) above, and the Company shall deliver the applicable number of Warrant Shares to the Warrantholder pursuant to the provisions of Section 1(c) above and this Section 1(d).

2.    CERTAIN ADJUSTMENTS.

(a)    Adjustment of Number of Warrant Shares and Exercise Price. The number and kind of Warrant Shares purchasable upon exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time as follows:

(i)    Subdivisions, Combinations and Other Issuances. If the Company shall at any time after the Date of Issuance but prior to the Expiration Date subdivide its shares of capital stock of the same class as the Warrant Shares, by split-up or otherwise, or combine such shares of capital stock, or issue additional shares of capital stock as a dividend with respect to any shares of such capital stock, the number of Warrant Shares issuable on the exercise of this Warrant shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the case of a combination. Appropriate adjustments shall also be made to the Exercise Price payable per share, but the aggregate Exercise Price payable for the total number of Warrant Shares purchasable under this Warrant (as adjusted) shall remain the same. Any adjustment under this Section 2(a)(i) shall become effective at the close of business on the date the subdivision or combination

2

becomes effective, or as of the record date of such dividend, or in the event that no record date is fixed, upon the making of such dividend.

(ii)    Reclassification, Reorganizations and Consolidation. In case of any reclassification, capital reorganization or change in the capital stock of the Company (other than as a result of a subdivision, combination or stock dividend provided for in Section 2(a)(i) above) that occurs after the Date of Issuance, then, as a condition of such reclassification, reorganization or change, lawful provision shall be made, and duly executed documents evidencing the same from the Company or its successor shall be delivered to the Warrantholder, so that the Warrantholder shall thereafter have the right at any time prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant, the kind and amount of shares of stock and/or other securities or property (including, if applicable, cash) receivable in connection with such reclassification, reorganization or change by a holder of the same number and type of securities as were purchasable as Warrant Shares by the Warrantholder immediately prior to such reclassification, reorganization or change. In any such case appropriate provisions shall be made with respect to the rights and interest of the Warrantholder so that the provisions hereof shall thereafter be applicable with respect to any shares of stock or other securities or property deliverable upon exercise hereof, and appropriate adjustments shall be made to the Exercise Price payable hereunder, provided the aggregate Exercise Price shall remain the same (and, for the avoidance of doubt, this Warrant shall be exclusively exercisable for such shares of stock and/or other securities or property from and after the consummation of such reclassification or other change in the capital stock of the Company).

(b)    Statement of Adjustment. Whenever the Exercise Price or number or type of securities issuable upon exercise of this Warrant is adjusted, as herein provided, the Company shall, at its expense, promptly deliver to the Warrantholder a certificate of an officer of the Company setting forth the nature of such adjustment and showing in reasonable detail the facts upon which such adjustment is based.

3.    NO FRACTIONAL SHARES. No fractional Warrant Shares or scrip representing fractional shares will be issued upon exercise of this Warrant. In lieu of any fractional shares which would otherwise be issuable, the Company shall pay cash equal to the product of such fraction multiplied by the Fair Market Value of one Warrant Share.

4.    NO STOCKHOLDER RIGHTS. Until the exercise of this Warrant or any portion of this Warrant, the Warrantholder shall not have, nor exercise, any rights as a stockholder of the Company (including without limitation the right to notification of stockholder meetings or the right to receive any notice or other communication concerning the business and affairs of the Company).

5.    RESERVATION OF STOCK. The Company covenants that during the period this Warrant is exercisable, the Company will reserve from its authorized and unissued Common Stock a sufficient number of shares of Common Stock (or other securities, if applicable) to provide for the issuance of Warrant Shares (or other securities) upon the exercise of this Warrant.

6.    MECHANICS OF EXERCISE. This Warrant may be exercised by the holder hereof, in whole or in part, by delivering to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Warrantholder at the address of the Warrantholder appearing on the books of the Company) a completed and duly executed copy of the Notice of Exercise in the form attached hereto as Exhibit A by mail or email attachment together with payment in full of the Exercise Price (unless the Warrantholder has elected to Net Exercise) then in effect with respect to the number of Warrant Shares as to which the Warrant is being exercised. This Warrant

3

shall be deemed to have been exercised immediately prior to the close of business on the date of the delivery to the Company of the Notice of Exercise as provided above, and the person entitled to receive the Warrant Shares issuable upon such exercise shall be treated for all purposes as the holder of such shares of record as of the close of business on such date. Warrant Shares purchased hereunder shall be transmitted by the Company’s transfer agent to the holder by crediting the account of the holder’s prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the holder or (B) the shares are eligible for resale by the holder without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery to the address specified by the holder in the Notice of Exercise by the end of the day on the date that is three trading days from the delivery to the Company of the Notice of Exercise and payment of the aggregate Exercise Price (unless exercised by means of a cashless exercise pursuant to Section 1(c)). The Warrant Shares shall be deemed to have been issued, and the holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (or by Net Exercise) and all taxes required to be paid by the holder, if any, prior to the issuance of such shares, having been paid.

7.    COMPLIANCE WITH SECURITIES LAWS; RESTRICTIVE LEGEND.

(a)    the Warrantholder on exercise of the Warrant will be acquired for investment for the Warrantholder’s own account and not with a view to the resale or distribution of any part thereof, and (b) that the Warrantholder is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”).

(b)    The Warrantholder understands that this Warrant and the Warrant Shares are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations this Warrant and the Warrant Shares may be resold without registration under the Securities Act only in certain limited circumstances.

(b)    This Warrant is exchangeable, without expense, at the option of the Warrantholder, upon presentation and surrender hereof to the Company for other warrants of different denominations entitling the holder thereof to purchase in the aggregate the same number of shares of Common Stock purchasable hereunder. This Warrant may be divided or combined with other warrants that carry the same rights upon presentation hereof at the principal office of the Company together with a written notice specifying the denominations in which new warrants are to be issued to the Warrantholder and signed by the Warrantholder hereof.

(i)    It is agreed that the 25% Shares held by TPH upon the formation of the JV is issued to TPH in exchange for the anticipated acquisition by the JV of the 49% interest of AFSW currently held by TPH pursuant to Section 7.1.2.

(i)    On or about 30 April 2023, TPH will enter into the Licensing Agreement with the JV, pursuant to which both the JV and the Designated Affiliate of JCP ("Designated Affiliate" as defined in the Supply and Distribution Agreement) will be granted, a royalty-free (fully paid-up), non-exclusive license from TPH under its applicable non-Epiwafer-related Intellectual Property Rights within the Territory (but excluding, for the avoidance of doubt, any Epiwafer-related Intellectual Property Rights or Intellectual Property Rights outside of the Territory), to use Epiwafers purchased from TPH to manufacture GaN processed wafers and develop GaN packaged products, solely for Greater China Customers.

(iii)    an agreement to second certain TPH employees for defined periods to the JV from time to time considering product needs of the JV and availability of TPH employees.

2.2.3    Subject to completion of the Stage II Transactions, (a) existing agreements between TPH and AFSW relating to wafer pricing terms and conditions, and, (b) subject to acceptance by JCP based on its due diligence review (which shall not be unreasonably refused), other existing agreements between TPH and AFSW, shall remain in place without modification and TPH and AFSW

shall continue to perform thereunder, provided that JCP (or its designated affiliate acceptable by TPH) shall be entitled to comparable pricing terms.

Business and Basis of Presentation

Business and Basis of Presentation

Transphorm, Inc. (“Parent”) develops gallium nitride (“GaN”) semiconductor components used in power conversion and is headquartered in Goleta, California. Parent’s wholly owned-subsidiary, Transphorm Technology, Inc. (“Transphorm Technology”), was incorporated in the State of Delaware on February 22, 2007. Throughout these notes, “the Company,” “Transphorm,” “we,” “us” and “our” refer to Parent and its direct and indirect wholly-owned subsidiaries. Transphorm Technology and its subsidiaries hold all material assets and conduct all business activities and operations of the Company. Transphorm Technology’s activities to date have been primarily performing research and development, establishing manufacturing infrastructure, market sampling, product launch, hiring personnel, and raising capital to support and expand these activities. Transphorm Japan, Inc. was established in Japan in February 2014 to secure Transphorm’s production capacity and establish a direct presence in Asian markets. Transphorm Aizu, Inc. was established in Japan to manage the financial transactions around Aizu Fujitsu Semiconductor Wafer Solution Limited, Transphorm’s non-controlling joint venture wafer fabrication facility located in Aizu Wakamatsu, Japan (“Aizu”). Transphorm Japan Epi, Inc. was established in Japan in 2019 to enable the operational capacity of the reactors held in Aizu.

In management’s opinion, the accompanying unaudited condensed consolidated financial statements of Transphorm reflect all adjustments of a normal and recurring nature that are necessary for a fair presentation of the results for the interim period ended September 30, 2021, but are not necessarily indicative of the results that will be reported for the entire year or any other interim period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with Accounting Principles Generally Accepted in the United States of America (“GAAP”) have been condensed or omitted. The aforementioned unaudited condensed consolidated financial statements are prepared in conformity with GAAP and in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. The interim information should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Transition Report on Form 10-K for the transition period from January 1, 2021 to March 31, 2021. The consolidated balance sheet as of March 31, 2021 is derived from those audited financial statements.

Change in Fiscal Year End

On April 20, 2021, we changed our fiscal year from the period beginning on January 1 and ending on December 31 to the period beginning on April 1 and ending on March 31 of each year, effective immediately. Accordingly, we filed a Transition Report on Form 10-K to include audited consolidated financial information for the transition period from January 1, 2021 through March 31, 2021.

Reverse Merger

On February 12, 2020, our wholly-owned subsidiary, Peninsula Acquisition Sub, Inc., a corporation formed in the State of Delaware (“Acquisition Sub”), merged with and into Transphorm Technology (formerly known as Transphorm, Inc.), the corporate existence of Acquisition Sub ceased, and Transphorm Technology became our wholly-owned subsidiary (such transaction, the “Merger”). As a result of the Merger, we acquired the business of Transphorm Technology. The Merger was effective as of February 12, 2020, upon the filing of a certificate of merger with the Secretary of State of the State of Delaware. Immediately after completion of the Merger, we adopted Transphorm Technology’s former company name, “Transphorm, Inc.”, as our company name.

The Merger was treated as a recapitalization and reverse acquisition for financial reporting purposes, and Transphorm Technology is considered the acquirer for accounting purposes.

As a result of the Merger and the change in our business and operations, a discussion of the past financial results of our predecessor, Peninsula Acquisition Corporation, is not pertinent, and under applicable accounting

principles, the historical financial results of Transphorm Technology, the accounting acquirer, prior to the Merger are considered our historical financial results.

At the effective time of the Merger, (i) each share of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger was converted into the right to receive (a) 0.08289152527 shares of our common stock (in the case of shares held by accredited investors) or (b) $4.00 multiplied by 0.08289152527 (in the case of shares held by unaccredited investors), with the actual number of shares of our common stock issued to the former holders of Transphorm Technology’s common stock equal to 4,171,571, (ii) 51,680,254 shares of Transphorm Technology’s Series 1 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 12,433,953 shares of our common stock, (iii) 38,760,190 shares of Transphorm Technology’s Series 2 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 7,499,996 shares of our common stock, and (iv) 31,850,304 shares of Transphorm Technology’s Series 3 preferred stock issued and outstanding immediately prior to the closing of the Merger were converted into 4,000,000 shares of our common stock. As a result, 28,105,520 shares of our common stock were issued to the former holders of Transphorm Technology’s issued and outstanding capital stock after adjustments due to rounding for fractional shares. Immediately prior to the effective time of the Merger, an aggregate of 682,699 shares of our common stock, owned by the stockholders of Peninsula Acquisition Corporation prior to the Merger, were forfeited and cancelled.

In addition, pursuant to the Merger Agreement, (i) options to purchase 29,703,285 shares of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger under Transphorm Technology’s 2007 Stock Plan (the “2007 Plan”) and 2015 Equity Incentive Plan (the “2015 Plan”) were assumed and converted into options to purchase 2,461,923 shares of our common stock, (ii) warrants to purchase 186,535 shares of Transphorm Technology’s common stock issued and outstanding immediately prior to the closing of the Merger were assumed, amended and converted into warrants to purchase 15,461 shares of our common stock, and (iii) Transphorm Technology’s outstanding convertible promissory note was amended to be convertible at the option of the holder, into shares of our common stock at a conversion price of $5.12 per share. As of September 30, 2021, there was $15.0 million of principal and $597 thousand of accrued and unpaid interest outstanding on the convertible promissory note.

All per share and share amounts for all periods presented have been retroactively adjusted to reflect the effect of the Merger.

Liquidity and Capital Resources

The Company’s ability to sustain operations is dependent mainly on its ability to successfully market and sell its products and through additional financings until profitability with positive cash flows are achieved. The Company currently incurs and historically has incurred losses from operations and expects to do so in the foreseeable future. The Company has sustained recurring losses and negative cash flows from operations which raised substantial doubt about the Company’s ability to continue as a going concern. During the six months ended September 30, 2021, the Company used $8.6 million of cash in operations. Although we expect to continue to incur losses and negative cash flows from operating activities, during November 2021, we raised $33.0 million from private placements. Consequently, the Company now has sufficient resources to fund its operations for the next twelve months from the date of this filing, and therefore, the substantial doubt about our ability to continue as a going concern has been alleviated. The Company may need to continue to raise additional capital to finance its losses and negative cash flows from operations beyond the next twelve months and may continue to be dependent on additional capital raises.

Impact of COVID-19 on Our Business

The COVID-19 pandemic has adversely disrupted and will further disrupt the operations at certain of our customers, partners, suppliers and other third-party providers for an uncertain period of time, including as a result of travel restrictions, adverse effects on budget planning processes, business deterioration, and/or business shutdowns, all of which has impacted our business and results of operations. Some of our customers have experienced delays in

their internal development programs and design cycles with our GaN products due to the effects of COVID-19, which have led to postponements of their orders of our products and postponements of determinations that our products will be used in their designs for new products under development with corresponding delays in their market introduction and our revenues. The future impact of COVID-19 cannot be predicted with certainty and may make it more difficult or preclude us from raising additional capital, increase our costs of capital and otherwise adversely affect our business, results of operations, financial condition and liquidity.

Significant Accounting Policies

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Parent and its wholly-owned subsidiaries, Transphorm Technology, Transphorm Japan, Inc., Transphorm Japan Epi, Inc. and Transphorm Aizu, Inc. Upon consolidation, all significant intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management bases its estimates and assumptions on historical experience, knowledge of current conditions, and its belief of what could occur in the future, given available information. Actual results could differ from those estimates, and such differences could be material to the consolidated financial statements. Estimates are used for, but not limited to, the determinations of fair value of stock awards and promissory notes, accrual of liabilities, revenue recognition, inventory reserve, and useful lives for property and equipment.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly-liquid investments with original maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist principally of bank deposits and money market funds. Restricted cash of $575 thousand consists of $500 thousand of cash in current asset and $75 thousand of long-term deposit in other assets as of September 30, 2021. Restricted cash as of March 31, 2021 includes $75 thousand of long-term deposit in other assets.

Foreign Currency Risk

The Company is exposed to foreign currency risk due to its operations in Japan (Yen). Assets and liabilities of the operations are re-measured into U.S. currency at exchange rates in effect at the balance sheet dates through the consolidated statements of comprehensive income. Gains or losses resulting from foreign currency transactions are re-measured using the rates on the dates on which those elements are recognized during the period and are included in other income or expense in the consolidated statements of operations. As of September 30, 2021 and March 31, 2021, the Company had foreign cash and cash equivalents of $60 thousand and $444 thousand, respectively, which represented 2.4 percent and 4.7 percent, respectively, of total cash and cash equivalents.

Concentrations of Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company is exposed to credit risk in the event of default by the financial institution holding its cash. The Company’s investment policy restricts investments to high-quality investments and limits the amounts invested with any one issuer, industry or geographic area. Risks associated with cash holdings in excess of insured limits are mitigated by banking with high-quality institutions. To date, the Company has not experienced any significant losses on its cash and cash equivalents. The Company periodically evaluates the relative credit standing of these financial institutions.

The Company is subject to risks common in the power conversion components industry, including, but not limited to, technological obsolescence, dependence on key personnel, market acceptance of its products, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed.

Comprehensive Loss

Comprehensive loss is comprised of net loss and other comprehensive income (loss). Other comprehensive income (loss) includes the impact of foreign currency translation adjustments.

Accounts Receivable

Accounts receivable are analyzed and allowances for uncollectible accounts are recorded, as required. Provisions for uncollectible accounts, if any, are recorded as bad debt expense and included in general and administrative expenses in the accompanying consolidated statements of operations. The process for determining the appropriate level of allowances for doubtful accounts involves judgment, and the Company considers such factors as the age of the underlying receivables, historical and projected collection trends, the composition of outstanding receivables, current economic conditions and regulatory changes. An account is fully reserved when reasonable collection efforts have been unsuccessful and it is probable that the receivable will not be recovered. Provision for doubtful accounts amounted to $0 and $86 thousand for the three months ended September 30, 2021 and 2020, respectively. Provision for doubtful accounts amounted to $0 and $146 thousand for the six months ended September 30, 2021 and 2020, respectively.

Inventory

Inventory is stated at the lower of cost (first-in, first-out method) or net realizable value. The Company periodically reviews the value of items in inventory and records write-downs or write-offs based on its assessment of slow moving or obsolete inventory. The Company maintains an inventory reserve for obsolete inventory and generally makes inventory value adjustments against the inventory reserve.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is determined using the straight-line method over the estimated useful lives of the respective assets, generally ranging from three to seven years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the related lease term. Depreciation for equipment commences once it is placed in service, and depreciation for buildings and leasehold improvements commences once they are ready for their intended use. The Company expenses maintenance and repair costs that do not extend the life of the asset as they are incurred.

The Company evaluates the carrying amount of its property and equipment whenever events or changes in circumstances indicate that the assets may not be recoverable. An impairment loss would be recognized when estimated future cash flows expected to result from the use of an asset or asset group and its eventual disposition are less than the carrying amount of the asset or asset group. To date, there have been no such impairment losses.

Goodwill

Goodwill arose for the acquisition of a business in February 2014 based in Japan and was accounted for as the purchase of a business. Goodwill generated from business combinations and deemed to have indefinite lives are not subject to amortization and instead are tested for impairment at least annually in December unless certain events occur or circumstances change. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. We test for goodwill impairment annually or earlier if events or changes in circumstances indicate goodwill might possibly be impaired. Impairment exists when the carrying value of the goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to

that excess as a charge to operations in the unaudited condensed consolidated statements of operations. For the three and six months ended September 30, 2021 and 2020, no impairment charge was recorded related to goodwill.

Intangible Assets

Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives, which generally range from three to ten years. Each reporting period, the Company evaluates the estimated remaining useful lives of intangible assets and whether events or changes in circumstances warrant a revision to the remaining periods of amortization.

If it is determined that the carrying values might not be recoverable based upon the existence of one or more indicators of impairment, the Company performs a test for recoverability using various methodologies, such as the income approach or cost approach, to determine the fair value of intangible assets depending upon the nature of the assets. If assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds their respective fair values. For the three and six months ended September 30, 2021 and 2020, no impairment charges were recorded related to intangible assets.

Revenue Recognition

The Company derives its revenues from sales of high-powered GaN-based products manufactured utilizing the Company’s proprietary and patented epiwafer technology and wafer fabrication and other assembly processes, sales of GaN epiwafers for the radio frequency (“RF”) and power markets, and sales of licenses to use such patented proprietary technology, as well as enabling EPI wafer growth services and products to our strategic partners. Revenues are recognized when control of these products or licenses are transferred to the Company’s customers in an amount that reflects the consideration it expects to be entitled to in exchange for those products and licenses. Sales and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. The Company does not have any significant financing components associated with its revenue contracts, as payment is received at or shortly after the point of sale.

Disaggregation of Revenue from Contracts with Customers

Revenue consists of licensing revenue, government contract revenue from our contract with the U.S. Navy and product sales, with applicable performance obligations satisfied at a point in time. Products are sold to distributors and end-users in various sectors such as, but not limited to, the automotive, gaming, industrial, IT, and consumer products industries.

As part of the multi-element commercial arrangement executed with Nexperia on April 4, 2018 (see Note 2 - Nexperia Arrangement), the Company agreed to grant Nexperia the perpetual exclusive right to use the Company’s existing Gen-3 manufacturing process technology. License fees are received upon satisfaction of contractual milestones and recognized upon delivery of the perpetual license or transferred technology without any remaining performance obligations. The Company recognized $8.0 million of licensing revenue for the three and six months ended September 30, 2021, and $0 and $5.0 million of licensing revenue for the three and six months ended September 30, 2020, respectively.

In December 2020, we entered into a cooperation and development agreement with Yaskawa Electric Corporation (“Yaskawa”), pursuant to which Yaskawa agreed to provide $4.0 million over approximately three years to fund development activities related to industrial power conversion applications, with an initial focus on servo motor drive applications. Yaskawa provided payments of $1.0 million and $750 thousand of this $4.0 million commitment in December 2020 and July 2021, respectively. The Company evaluated and concluded that the deliverables are the same and nature of the services to be provided to Yaskawa will be consistent over the period of approximately three years. Accordingly, with respect to the $1.0 million payment, the Company recognized $333 thousand as revenue in each of the three months ended December 31, 2020, March 31, 2021 and June 30, 2021

and, with respect to the $750 thousand payment, the Company recognized $375 thousand as revenue for the three months ended September 30, 2021.

Government contract revenues are principally generated under research and development contracts. Contract revenues are derived primarily from research contracts with agencies of the U.S. government. We believe credit risk related to accounts receivable arising from such contracts is minimal. These contracts may include cost-plus fixed fee and fixed price terms. All payments to us for work performed on contracts with agencies of the U.S. government are subject to adjustment upon audit by the Defense Contract Audit Agency. The Company received new government authorized rates for billing purposes which allowed for retroactive application since inception. The cumulative impact of this rate change as of September 30, 2021 was $423 thousand, of which $(83) thousand and $505 thousand were recorded in the three months ended March 31, 2021 and September 30, 2020, respectively. The Company will use the new approved rates on a go-forward basis.

Performance Obligations

For performance obligations related to the sale of products, control transfers to the customer at a point in time. The Company’s principal terms of sale are free on board shipping or destination and the Company transfers control and records revenue for product sales upon shipment or delivery to the customer, respectively. For performance obligations related to the licensing of patented technology in perpetuity, control also transfers to the customer at a point in time. The Company transfers control and records revenue for licensing fees once the Company has (i) provided or otherwise makes available the patented technology to the customer and (ii) the customer is able to use and benefit from the patented technology.

Variable Consideration

The nature of the Company’s arrangement with Nexperia gives rise to variable consideration in the form of milestone and royalty payments. The royalties qualify for the sales and usage-based royalty exception, as the license of intellectual property is the predominant item to which the royalty relates and are recognized upon the subsequent sale occurring. The variable amounts are received upon satisfaction of contractually agreed upon development targets and sales volume.

Research and Development

The Company is a party to research grant contracts with the U.S. government for which the Company is reimbursed for specified costs incurred for its research projects. These projects include energy saving initiatives for which the U.S. government offers reimbursement funds. Such reimbursements are recorded as an offset to research and development expenses when the related qualified research and development expenses are incurred. Reimbursable costs are recognized in the same period the costs are incurred up to the limit of approved funding amounts on qualified expenses. Grant reimbursement of $45 thousand and $81 thousand was recorded as an offset to research and development expense for the three months ended September 30, 2021 and 2020, respectively. Grant reimbursement of $72 thousand and $307 thousand was recorded as an offset to research and development expense for the six months ended September 30, 2021 and 2020, respectively.

Stock-Based Compensation

All share-based payments, including grants of stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), are measured at the fair value of the share-based awards on the grant date and recognized over their respective vesting periods, which is generally one to four years. The estimated fair value of stock options at the grant date is determined using the Black-Scholes-Merton pricing model. The RSAs and RSUs are measured using the estimated fair value of the stock price, which, due to limited trading history, is based on recent equity sales. The Company recognizes the fair value of share-based payments as compensation expense for all expected-to-vest stock-based awards over the vesting period of the award using the straight-line attribution or graded vesting method provided that the amount of compensation cost recognized at any date is no less than the portion of the grant-date fair value of the award that is vested at that date.

The Black-Scholes-Merton option pricing model requires inputs such as the fair value of common stock on date of grant, expected term, expected volatility, dividend yield, and risk-free interest rate. Further, the forfeiture rate also affects the amount of aggregate compensation expense. These inputs are subjective and generally require significant analysis and judgment to develop. Volatility data is obtained from a study of publicly traded industry peer companies. The forfeiture rate is derived primarily from the Company’s historical data, and the risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues commensurate with the expected term. Management generally uses the simplified method to calculate the expected term for employee grants as the Company has limited historical exercise data or alternative information to reasonably estimate an expected term assumption. The simplified method assumes that all options will be exercised midway between the weighted average vesting date and the contractual term of the option.

Stock-based compensation expense recognized in the Company’s unaudited condensed consolidated financial statements is based on awards that are expected to vest. These expense amounts have been reduced by using an estimated forfeiture rate. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company evaluates the assumptions used to estimate forfeitures annually in connection with the recognition of stock-based compensation expense.

Income (Loss) Per Share

Basic income (loss) per share is calculated by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is calculated by dividing the net loss attributable to common stockholders by the sum of the weighted average number of common shares outstanding plus potential dilutive common shares outstanding during the period. Potential dilutive securities, comprised of stock warrants, restricted stock units and stock options, are not reflected in diluted income (loss) per share because such shares are anti–dilutive. Dilutive impact of potential common shares resulting from common stock equivalents is determined by applying the treasury stock method.

For the three months ended September 30, 2021, there were 2,548,731 shares, consisting of 2,330,316 stock options and 218,415 stock warrants, that were not included in the computation of diluted income per share because their effect would be anti-dilutive. For the six months ended September 30, 2021, there were 3,826,583 shares, consisting of 2,506,531 stock options, 951,637 restricted stock units and 368,415 stock warrants, that were not included in the computation of diluted loss per share because their effect would be anti-dilutive. For the three and six months ended September 30, 2020, there were 3,155,064 shares, consisting of 2,327,423 stock options, 812,180 restricted stock units and 15,461 stock warrants, that were not included in the computation of diluted loss per share because their effect would be anti-dilutive.

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The carrying values of the Company’s financial instruments such as cash equivalents, accounts receivable, revolving credit facility, accounts payable and accrued liabilities approximate fair values due to the short-term nature of these items. The Company has elected the fair value option for its promissory notes.

Income Taxes

The Company accounts for income taxes in accordance with Accounting Standards Codification (“ASC”) 740, Income Taxes (“ASC 740”). ASC 740 prescribes the use of the liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted statutory tax rates in effect at the balance sheet date. The Company records a valuation allowance to reduce its deferred tax assets when uncertainty regarding their realizability exists.

Equity Method Investments

The Company uses the equity method to account for investments in entities that it does not control, but in which it has the ability to exercise significant influence over operating and financial policies. The Company's proportionate share of the net income or loss of these companies is included in consolidated net loss. Judgments regarding the level of influence over each equity method investment include consideration of key factors such as the Company's ownership interest, representation on the board of directors or other management body and participation in policy-making decisions.

Segment Reporting

The Company’s operations and its financial performance is evaluated on a consolidated basis by the chief operating decision maker. The Company’s chief operating decision maker is the Parent’s Chief Executive Officer. Accordingly, the Company considers all of its operations to be aggregated in one reportable operating segment. For the three months ended September 30, 2021, total revenue was $11.3 million, of which $11.3 million was from U.S. operations and $27 thousand was from Japan operations. For the three months ended September 30, 2020, total revenue was $1.9 million, of which $1.6 million was from U.S. operations and $289 thousand was from Japan operations. For the six months ended September 30, 2021, total revenue was $14.5 million, of which $14.0 million was from U.S. operations and $498 thousand was from Japan operations. For the six months ended September 30, 2020, total revenue was $8.3 million, of which $7.9 million was from U.S. operations and $319 thousand was from Japan operations.

Recently Issued Accounting Standards under Evaluation

Debt - In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, to address the complexity in accounting for certain financial instruments with characteristics of liabilities and equity. Amongst other provisions, the amendments in this ASU significantly change the guidance on the issuer’s accounting for convertible instruments and the guidance on the derivative scope exception for contracts in an entity’s own equity such that fewer conversion features will require separate recognition, and fewer freestanding instruments, like warrants, will require liability treatment. Refer to our white paper, Accounting simplifications for convertible instruments and warrants, for additional information. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Leases - In June 2020, the FASB issued ASU 2020-05, which amends the effective dates of the FASB’s standards on leasing (ASC 842) to give immediate relief to certain entities as a result of the widespread adverse economic effects and business disruptions caused by the COVID-19 pandemic. In February 2016, the FASB issued ASU 2016-02, Leases, which, for operating leases, requires the lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, on its balance sheet. The guidance also requires a lessee to recognize single lease costs, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. The leasing standard’s effective dates were the fiscal year beginning after December 15, 2019 as originally issued (ASU 2016-02) and the fiscal year beginning after December 15, 2020 as amended by ASU 2019-10. As amended by ASU 2020-05, the leasing standard’s effective date is now the fiscal year beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Financial Instruments - FASB ASU 2020-03, Codification Improvements to Financial Instruments, makes clear the determination of the contractual life of a net investment in leases in estimating expected credit losses under ASC 326, Financial Instruments – Credit Losses. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nexperia Arrangement

Nexperia Arrangement

Nexperia Transaction

On April 4, 2018, the Company entered into a multi-element commercial arrangement with Nexperia B.V. (“Nexperia”) to obtain financing in exchange for the sale of equity instruments and performing certain technology and product development activities for Nexperia (collectively, the “Collaboration Arrangement”). Nexperia specializes in designing, manufacturing and selling a broad range of small discrete semiconductor devices that utilize components such as those manufactured by the Company. Financing under the Collaboration Arrangement is comprised of the following elements:

•$16 million Series 3 preferred stock issuance

•$9 million license fee for transfer of the Gen-3 manufacturing process

•$5 million development loan, originally maturing March 31, 2020 and subsequently extended to June 30, 2020 intended to pre-fund the Gen-4 (Tranche A) technology development (the “Tranche A Loan”)

•$10 million development loan maturing March 31, 2021 intended to pre-fund the Gen-5 and 1200V technology development (the “Tranche B Loan”)

•$10 million revolving loan (the “Tranche C Loan”)

The Company has to use the funds to operate the business in a manner consistent with or reasonably related to those business activities as carried out on or prior to April 4, 2018, the effective date of Collaboration Arrangement. In addition to the multiple elements outlined above, the Company and Nexperia entered into a Supply Agreement requiring that the Company be Nexperia’s primary supplier of specified components until June 30, 2020 on a best efforts basis. By entering into this Collaboration Arrangement, Nexperia gained access to technology that allows for production of high power semiconductors for use in electric vehicles.

Further, Nexperia obtained an exclusive license and market access to automotive customers outside of Japan and a sole license (non-exclusive of the Company), as well as market access to customers in other parts of the power market. Nexperia has a lien on certain of the Company’s U.S. patents not relating to metal organic chemical vapor deposition (“MOCVD”) or epiwafer technology, per the agreement.

On March 31, 2019, the Company executed Amendment No. 1 to the Loan and Security Agreement (the ”LSA”), pursuant to which the Tranche B Loan was bifurcated into the following two separate sub-tranches:

•$8 million development loan intended to pre-fund the Gen-5 (Tranche B) technology development (the “Tranche B Loan”)

•$2 million development loan intended to pre-fund the 1200V technology development (the “Tranche B-1 Loan” and, together with the Tranche B Loan, the “Tranche B Loans”)

On February 7, 2020, Amendment No. 2 to the LSA was executed to acknowledge the then-pending Merger, reaffirm the terms of the loans and confirm the waiver for the late delivery of the Company’s 2018 audited financial statements. On April 8, 2020, Amendment No. 3 to the LSA was executed to extend the maturity of the Tranche A Loan to April 30, 2020. On April 28, 2020, Amendment No. 4 to the LSA was executed to further extend the maturity of the Tranche A Loan to June 30, 2020. All other terms set forth under the original LSA remained unchanged following the amendments.

The Tranche A and Tranche B Loans represent pre-funding for Gen-4 (Tranche A), Gen-5 (Tranche B), and 1200V (Tranche B-1) technology development for Nexperia. The specific development activities and associated performance milestones are contained within a Statement of Work (“SoW”) between the Company and Nexperia. The SoW may be modified from time to time based upon mutual business interests. This promise to perform the technology development is a good/service provided to a customer in exchange for consideration in the form of the technology development license fees that offset the Tranche A and Tranche B Loans outstanding. The Development Loans are recognized as a liability equal to the cash proceeds received.

In relation to the license fee for the transfer of the Company’s Gen-3 manufacturing process to Nexperia, the Company received $3 million (the first of three tranches) in October 2018, $3 million (the second of three tranches) in April 2019, and $3 million (the third of three tranches) in October 2019. The Company recognized $9.0 million as licensing revenue during 2019 upon the completion of the transfer of the Company’s Gen-3 manufacturing process technology and mutual sign off between Nexperia and the Company.

In January 2019, the Company received the $5 million Tranche A Loan. In June 2020, Nexperia agreed that the $5 million Tranche A Loan was permanently satisfied in full in connection with the Company transferring its Gen-4 technology development to Nexperia, at which point the Company recognized $5 million as licensing revenue. In June and July 2019, the Company received the $8 million Tranche B Loan. In December 2019, the Company received the $2 million Tranche B-1 Loan.

The Company received the full $10 million Tranche C Loan under the credit facility during the year ended December 31, 2018. See Note 6 - Debts.

On March 1, 2021, Amendment No. 5 to the LSA was executed to extend the maturity of the Tranche B loans of $10 million and the Tranche C Loan of $10 million to June 30, 2021 and May 18, 2021, respectively.

On May 18, 2021, Amendment No. 6 to the LSA was executed to (1) extend the maturity date for the Tranche C Loans to the earlier of April 4, 2023 and the occurrence of specified change of control events, (2) add Parent as a guarantor of Transphorm Technology’s obligations under the Loan Agreement, and (3) convert the outstanding $2 million Tranche B-1 Loan into a Tranche C-1 Loan, which Tranche C-1 Loan has the same terms and conditions as the existing Tranche C Loan.

On May 18, 2021, in addition to Amendment No. 6 to the LSA, the Company entered into a series of agreements with Nexperia, as described below.

Strategic Cooperation Agreement

The strategic cooperation agreement serves as a framework agreement that describes the numerous agreements between the parties and provides Nexperia with information rights and inspection rights with respect to the Company’s business.

Option Agreement

The option agreement establishes the parameters pursuant to which Nexperia, in certain limited instances, is permitted to exercise an option (the “Option”) to acquire Transphorm Japan Epi, Inc. (“TJE”), a Japanese subsidiary of the Company through which the Company is engaged in the development, manufacturing and sales of gallium nitride (“GaN”) based epitaxial wafer products. In general, the Option is exercisable upon (1) certain acquisitions of securities or assets of the Company or its subsidiaries by a Competitor (as defined in the option agreement) that results in the Company, directly or indirectly, owning less than a majority of TJE, which acquisition is followed by any material breach (that is not cured within a specified time period) by the Company or a subsidiary of its obligations with respect to epiwafer supply to Nexperia under the Company’s amended and restated supply agreement (the “Supply Agreement”) with Nexperia, or (2) the unilateral termination by the Company of the Supply Agreement. The option agreement also establishes the material terms, including price and timing, for the exercise of the Option by Nexperia. The Option terminates (1) if the Option is not exercised by Nexperia prior to the date on which the option agreement terminates, or (2) on the first to occur of (a) the termination of the option agreement upon written agreement of the parties, (b) the mutual termination or expiration of the Supply Agreement, or (c) the first to occur of (i) two years following the date on which the Company notifies Nexperia of epiwafer qualification of a second source and (ii) April 1, 2028.

In connection with the option agreement, the Company has also amended and restated its existing intracompany license agreement with TJE to clarify Nexperia’s rights upon exercise of the Option.

Amended and Restated Development and License Agreement

The Company entered into an amended and restated development and license agreement (the “DLA”) with Nexperia, pursuant to which the Company agreed to develop and transfer to Nexperia certain manufacturing process technologies to enable Nexperia to manufacture GaN-based products at Nexperia’s facilities. These technologies to be transferred included the Company’s Gen-3, Gen-4 (Tranche A), and Gen-5 (Tranche B) process technologies, but do not include the Company’s Epi Process Technology (as defined in the DLA). Nexperia also agreed to provide funding for the development of such technologies in return for limited exclusivities in automotive and other fields. Nexperia’s rights now include sale of products in the automotive field in Japan along with Transphorm’s rights for sale of products in the automotive field in Japan which remain in place. As per the original agreement, after April 2023, Nexperia’s exclusive rights for sale of products in the automotive field outside of Japan terminate. In addition, the parties have clarified the ability of Nexperia’s customers to use products developed by Nexperia through exercise of its rights under this agreement.

Amended and Restated Supply Agreement

The Company entered into the Supply Agreement with Nexperia, which sets forth the terms under which Nexperia may purchase epiwafers and processed wafers from the Company, and the Company may purchase processed wafers from Nexperia. The agreement specifies that Nexperia is the Company’s priority customer with respect to epiwafers manufactured by TJE and, accordingly, has preferred utilization of extra capacity, and further specifies procedures to address expansion of the Company’s epiwafer manufacturing capacity and Nexperia’s obligations with respect thereto. The term of the Supply Agreement was extended until December 31, 2025, with automatic one year renewals thereafter, and the Company may not terminate the Supply Agreement while the Option Agreement is in effect.

On June 30, 2021, Amendment No. 7 to the LSA was executed to extend the maturity of the Tranche B loans of $8 million to July 16, 2021.

On July 16, 2021, Nexperia agreed that the $8 million Tranche B Loan was satisfied in full in connection with the Company transferring its Gen-5 and 1200V technology developments to Nexperia, at which point the Company recognized $8 million as licensing revenue.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

FASB ASC 820, Fair Value Measurements and Disclosures, establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

Level 1 - Unadjusted quoted prices in active markets for identical assets and liabilities.

Level 2 - Inputs (other than quoted prices included within Level 1) that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data of substantially the full term of the related assets or liabilities.

Level 3 - Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Inputs are unobservable for the asset or liability. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following table summarizes the Company’s liabilities measured at fair value as of the dates presented, by level within the fair value hierarchy (in thousands):

	Level 1		Level 2		Level 3
September 30, 2021
Promissory note	$	—	$	—	$	15,597
March 31, 2021
Promissory note	$	—	$	—	$	16,128

The following table includes the changes in fair value of the promissory note which are Level 3 on the fair value hierarchy (in thousands):

April 1, 2021	$	16,128
Interest expense accrued	74
Increase in fair value	(605)
September 30, 2021	$	15,597
April 1, 2020	$	13,885
Interest expense accrued	150
Increase in fair value	2,093
March 31, 2021	$	16,128

The Company recorded interest expense of $36 thousand and $38 thousand for the three months ended September 30, 2021 and 2020, respectively. The Company recorded interest expense of $74 thousand and $75 thousand for the six months ended September 30, 2021 and 2020, respectively. Fair value of promissory note decreased by $1.6 million and increased by $709 thousand for the three months ended September 30, 2021 and 2020, respectively. Fair value of promissory note decreased by $605 thousand and increased by $2.4 million for the six months ended September 30, 2021 and 2020, respectively.

Level 3 borrowings, which consist of a promissory note, are measured and reported at fair value. As conversion of the promissory note was completed on October 4, 2021, at September 30, 2021, as-converted valuation model was used for the promissory note and a Monte Carlo simulation valuation model was used for warrants issued to purchase shares of common stock upon conversion. Assumptions used for the warrants are a three year term, exercise price of $6.00, risk free rate of 0.53% and volatility of 48.0%. See Note 12 - Subsequent Events.

A Monte Carlo simulation valuation model was used at March 31, 2021. The models can include assumptions related to the value of the notes that are based on the estimated timing and amounts of future rounds of financing, including the estimated timing of a change in control of the Company, and estimated market interest rates, which represent significant unobservable inputs. Assumptions used are (1) the Company is worth today what it can generate in future cash to the Company, (2) cash received today is more than an equal amount of cash received in the future, and (3) future cash flows can be reasonably estimated. There were no transfers in or out of level 3 fair value instruments.

The following table summarizes assumptions used for fair value of promissory note as of the dates presented:

	September 30, 2021	March 31, 2021
Stock price	$4.75	$3.75
Time	—	1.5 years
Risk-free rate	—	0.12%
Volatility	48.0%	50.6%

Fair value of promissory note decreased $605 thousand and increased $2.4 million for the six months ended September 30, 2021 and 2020, respectively.

In October 2017, the Company issued an unsecured subordinated convertible promissory note to Yaskawa (the “Yaskawa Note”) for $15.0 million. The stated interest rate of the Yaskawa Note is 1.0%, and principal plus interest is due on the earlier of September 30, 2022, or the date of the occurrence of an Event of Default, Change of Control or an Initial Public Offering (all terms as defined in the Yaskawa Note). In connection with the Merger, the Yaskawa Note was amended to be convertible at the option of the holder into a maximum of 3,076,171 shares of our common stock at a conversion price of $5.12 per share.

On October 4, 2021, the Company entered into a Note Amendment and Conversion Agreement with Yaskawa to (i) reduce the conversion price of the Yaskawa Note from $5.12 per share to $5.00 per share and (ii) remove the limitation on the maximum number of shares of the Company’s stock that may be issued upon conversion of the Yaskawa Note. Yaskawa simultaneously elected to convert the outstanding principal amount (plus accrued but unpaid interest) under the Yaskawa Note, which as of the effective date of the conversion totaled $15.6 million, into an aggregate of 3,120,000 shares of our common stock. The Company also issued to Yaskawa a warrant to purchase up to 650,000 shares of common stock at an exercise price of $6.00 per share with a term of three years. See Note 12 - Subsequent Events.

Investment in Aizu Fujitsu Semiconductor Wafer Solution Limited ("AFSW")

6 Months Ended

Sep. 30, 2021

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Investment in Aizu Fujitsu Semiconductor Water Solution Limited ("AFSW")

Investment in Aizu Fujitsu Semiconductor Wafer Solution Limited (“AFSW”)Through July 31, 2021, the Company was party to a joint venture agreement (the “JVA”), by and among Aizu Fujitsu Semiconductor Limited, Fujistu Semiconductor Limited (“FSL”), the Company and Transphorm Aizu, Inc. (“Transphorm Aizu”) for the ownership and operations of AFSW. Through July 31, 2021, the Company held a 49% interest in AFSW through Transphorm Aizu, the Company’s wholly-owned subsidiary established in Japan to manage the financial transactions around AFSW. Transphorm Aizu and FSL funded AFSW based on a mutually agreed funding schedule, which was adjusted as agreed upon by both parties during the three months ended September 30, 2021. Any outstanding balances were reviewed upon the conclusion of the JVA effective July 31, 2021 to assess unfunded commitment to joint venture liability. During the three and six months ended September 30, 2021, the Company recognized a $1.5 million gain, in other income, upon termination of the JVA and settlement of its obligation.

On April 1, 2020, FSL exercised its put option under the JVA and notified us that FSL intended to exit the joint venture by selling its 51% interest in AFSW to us. In December 2020, the Company entered into a joint venture agreement with JCP Capital Management, LLC (controlling party with 75% ownership) to create GaNovation, a joint venture company in Singapore, to engage in the business of distribution, development and supply of GaN products and, upon approval of the regulatory authorities in Japan, to purchase FSL’s and Transphorm’s interests in AFSW. In July 2021, regulatory authorities in Japan approved GaNovation’s purchase of 100% of the interests in AFSW from Transphorm and FSL. On July 20, 2021, Transphorm Aizu entered into a Share Purchase Agreement (the “Purchase Agreement”) with GaNovation, pursuant to which GaNovation agreed to acquire Transphorm’s 49% interest in AFSW from Transphorm Aizu for 1 Japanese Yen. The closing of the Purchase Agreement occurred on August 1, 2021. Following the closing of the Purchase Agreement and other concurrent transactions between GaNovation and FSL, Transphorm, through GaNovation, holds a 25% interest in AFSW (down from the previous 49%). For at least one year following the closing, we have agreed to use our best efforts to maintain the operations of AFSW.

AFSW manufactures semiconductor products exclusively for its owners under manufacturing agreements at prices estimated to cover the cost of production. AFSW was determined to be a variable interest entity as the equity at risk was not believed to be sufficient. AFSW depends on its owners for any additional cash. The Company extended $3.1 million and $3.8 million to AFSW to fund AFSW’s operations for the six months ended September 30, 2021 and 2020, respectively. The Company’s known maximum exposure to loss approximated the carrying value of its investment balance, which included the financing. Potential future losses could be higher than the carrying amount of the Company’s investment, as we are liable, along with the other owner, for other future operating costs or obligations of AFSW. In addition, because Transphorm is currently committed to purchasing GaN wafers and production-related services from AFSW at pre-agreed pricing based upon the Company’s second generation products, the Company may be required to purchase products at a higher cost for its newer generation products. Investment in AFSW was $89 thousand as of September 30, 2021 and unfunded commitment to AFSW was $1.9 million as of March 31, 2021.

The Company’s investment activities in AFSW for the periods presented are summarized below (in thousands):

Commitments and Contingencies

Commitments and Contingencies

Commitment with a Government Agency

In connection with a contract with a government agency, the Company entered into a commitment to acquire equipment and services from vendors totaling $7.4 million, all of which is reimbursable. The Company has made total purchases of $7.1 million cumulatively as of September 30, 2021, of which $7.1 million was reimbursed by the government agency as of September 30, 2021. During the three and six months ended September 30, 2021, the Company made purchases of $116 thousand and $228 thousand, respectively, and the remaining accounts payable to the vendors was $47 thousand as of September 30, 2021. For the three months ended March 31, 2021, the Company made purchases of $270 thousand, of which $124 thousand was in accounts payable as of March 31, 2021.

In September 2021, the Company was awarded a $0.9 million contract with a $0.5 million option by a government agency for delivering epiwafer technology. The Company billed $3 thousand for the three and six months ended September 30, 2021.

Operating Leases

The Company leases office and fabrication space in Goleta, California, and office space in Campbell, California and in Japan under noncancelable operating lease agreements. The terms of certain leases provide for escalating rental payments through the term of the lease. The Company recognizes rent expense on a straight-line basis over the lease term and accrues for rent expense incurred but not paid.

As of September 30, 2021, future minimum operating lease commitments were as follows (in thousands):

Year Ending March 31,
2022	$	317
2023	566
2024	570
Thereafter	144
Total	$	1,597

The Company recorded rent expense, net of rental income, which includes common area maintenance fees in addition to the base rent, of $240 thousand and $228 thousand for the three months ended September 30, 2021 and 2020, respectively, and of $465 thousand and $422 thousand for the six months ended September 30, 2021 and 2020, respectively. Rental income from a noncancelable sublease was $0 and $45 thousand for the three months ended September 30, 2021 and 2020, respectively, and $0 and $91 thousand for the six months ended September 30, 2021 and 2020, respectively. As of September 30, 2021, there is no the future minimum rental payments to be received under the noncancelable sublease.

Contingencies

During the ordinary course of business, the Company may become a party to legal proceedings incidental to its business. The Company accrues contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. Legal cost is expensed as incurred. The Company is not aware of any material legal claims or assessments. Although the results of litigation and claims are inherently unpredictable, management believes there was not at least a reasonable possibility that the Company had incurred a material loss with respect to any loss contingencies as of September 30, 2021 and through the issuance of these financial statements.

Indemnification

The Company from time to time enters into types of contracts that contingently require the Company to indemnify parties against third-party claims. These contracts primarily relate to: (1) real estate leases, under which the Company may be required to indemnify property owners for environmental and other liabilities and for other claims arising from the Company’s use of the applicable premises; (2) agreements with the Company’s officers, directors, and employees, under which the Company may be required to indemnify such persons from liabilities arising out of their relationship; (3) indemnifying customers in the event of product failure; and (4) agreements with outside parties that use the Company’s intellectual property, under which the Company may indemnify for copyright or patent infringement related specifically to the use of such intellectual property.

Historically, the Company has not been required to make payments under these obligations, and no liabilities have been recorded for these obligations in the Company’s unaudited condensed consolidated financial statements.

The total number of shares of stock that the Company shall have authority to issue is 755,000,000 shares, of which 750,000,000 shares are common stock, $0.0001 par value per share, and 5,000,000 shares are preferred stock, $0.0001 par value per share.

In April 2021, the Company issued 97,099 shares of common stock as payment of $500 thousand for one year internet advertising contract with SRAX, Inc.

As of September 30, 2021, 750,000,000 shares of common stock are authorized, of which 41,664,020 shares of common stock were issued and outstanding and 5,000,000 shares of preferred stock are authorized, none of which were issued and outstanding. The Company’s Board of Directors has the ability to designate the rights, preferences and privileges for the preferred stock.

Private Placements

On February 12, 2020 and February 27, 2020, we sold an aggregate of 5,380,000 shares of common stock in a private placement offering at a purchase price of $4.00 per share, with aggregate gross proceeds of $21.5 million (before deducting placement agent fees and other offering expenses, which were an aggregate of $1.8 million).

Common Stock

Common stockholders are entitled to dividends, as and when declared by the Company’s Board of Directors, subject to the priority dividend rights of the holders of other classes of stock. There have been no dividends declared to date. The holder of each share of common stock is entitled to one vote.

The Company has reserved shares of common stock for future issuance as of date presented as follows:

	September 30, 2021
Equity incentive plans	7,030,699
Common stock warrants	368,415
Total	7,399,114

Common Stock Warrants

On December 23, 2020, we issued warrants to purchase 150,000 shares of common stock at an exercise price of $3.30 per share. On August 13, 2021, we issued warrants to purchase 209,000 shares of common stock at an exercise price of $6.00 per share. These warrants are exercisable by paying cash or by cashless exercise for unregistered shares of common stock. The exercise price of the warrants is subject to standard antidilutive provision adjustment in the case of stock dividends or other distributions on shares of common stock or any other equity or equity equivalent securities payable in shares of common stock, stock splits, stock combinations, reclassifications or similar events affecting our common stock, and also, subject to limitations, upon any distribution of assets, including cash, stock or other property to our stockholders. The exercise price of the warrants is not subject to “price-based” anti-dilution adjustment. We have determined that these warrants related to issuance of common stock are subject to equity treatment because warrantholders have no right to demand cash settlement and there are no unusual anti-dilution rights.

The following warrants to purchase common stock were outstanding as of September 30, 2021:

Number of Shares	Exercise Price		Expiration Date
6,046	$	34.74	5 years after an initial public offering of the Company
3,369	$	54.41	5 years after an initial public offering of the Company
150,000	$	3.30	December 23, 2025
209,000	$	6.00	August 13, 2024
368,415

On October 4, 2021, the Company issued to Yaskawa a warrant to purchase up to 650,000 shares of common stock at an exercise price of $6.00 per share. The warrant has a term of three years (subject to earlier termination as set forth therein), provides for a cashless exercise feature and is immediately exercisable.

Stock Based Compensation

Share-based Payment Arrangement [Abstract]

Stock Based Compensation

Stock Based CompensationThe 2020 Equity Incentive Plan (the “2020 Plan”) was approved by Transphorm Technology’s board of directors on February 10, 2020 and Transphorm Technology’s stockholders on February 12, 2020, and became effective on the business day immediately prior to the closing of the Merger. Our stockholders approved the 2020 Plan on February 11, 2020. We assumed the 2020 Plan in connection with the Merger. The 2020 Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), to our employees and our parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance units, and performance shares to our employees, directors, and consultants and our parent and subsidiary corporations’ employees and consultants. As of September 30, 2021, there were 951,637 restricted stock units

outstanding under the 2020 Plan, 2,506,531 stock options outstanding under the 2020 Plan, and 3,572,531 shares available for grant (which includes an automatic increase of 2,026,599 shares on April 1, 2021) under the 2020 Plan.

Subject to the adjustment provisions of the 2020 Plan, and the automatic increase described in the 2020 Plan, the maximum aggregate number of shares of our common stock that may be issued under the 2020 Plan is 5,050,000 shares of our common stock, which includes (i) 2,588,077 shares initially reserved for issuance, plus (ii) any shares of our common stock subject to issued and outstanding awards under the 2007 Plan or 2015 Plan that were assumed in the Merger and that, on or after the closing of the Merger, expire or otherwise terminate without having been exercised or issued in full, are tendered to or withheld by us for payment of an exercise price or for tax withholding obligations, or are forfeited to or repurchased by us due to failure to vest, with the maximum number of shares to be added to the 2020 Plan pursuant to this clause (ii) equal to 2,461,923 shares. Subject to the adjustment provisions of the 2020 Plan, the number of shares of common stock available for issuance under the 2020 Plan will also include an annual increase on the first day of each fiscal year beginning with our 2022 fiscal year and ending on (and including) our 2030 fiscal year, in an amount equal to the least of: 5,000,000 shares of our common stock; five percent (5%) of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year; or such number of shares of our common stock as the administrator of the 2020 Plan may determine.

(1) Intrinsic value represents the excess of the fair value on the last day of the period, which was $4.52 and $4.00 as of September 30, 2021 and 2020, respectively, over the exercise price, multiplied by the number of options.

Stock-based compensation expense is determined based on the fair value of the Company’s common stock as determined by the Board of Directors and assumptions such as volatility, expected term, risk-free interest rates, and other factors. Changes in the deemed fair value of the common stock, the underlying assumptions in the calculations, the number of options granted or the terms of such options, the expected forfeiture rate, the treatment of tax benefits and other changes may result in significant differences in the amounts or timing of the compensation expense recognized. The assumptions and estimates are made as follows:

•Expected Volatility - The Company utilizes the historical volatility of representative public companies to determine its expected volatility, as the trading history of the Company’s common stock is limited.

•Estimated Forfeitures - The Company adopted ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting and has elected to account for forfeitures as they occur and therefore, stock-based compensation expense has been calculated based on actual forfeitures in the statements of operations, rather than our previous approach which was net of estimated forfeitures. The net cumulative effect of this change was not material.

•Expected Dividend Yield - The Company has not issued any common stock dividends; therefore, a dividend yield of zero was used.

•Risk-Free Interest Rate - The Company bases the risk-free interest rate used in the Black-Scholes-Merton option pricing model on the implied yield currently available on United States Treasury zero-coupon issues with an equivalent expected term.

•Expected Term - The expected term of stock options represents the period that the Company’s stock options are expected to be outstanding. The Company generally uses the simplified method to calculate the expected term for employee grants.

The assumptions used to value options granted to employees during the periods presented was as follows:

	Three and Six Months Ended September 30,
	2021	2020
Weighted average expected life (in years)	6.11	—
Risk-free interest rate	1.08%	—
Expected volatility	43.79%	—
Grant date fair market value	$4.50	—
Grant date fair value	$1.94	—
Dividend yield	—%	—

Restricted Stock

Restricted Stock Awards

RSAs are grants of shares of our common stock that vest in accordance with terms and conditions established by the Company’s Board of Directors. Recipients of RSAs generally will have voting and dividend rights with respect to such shares upon grant without regard to vesting, unless the RSA agreement provides otherwise. Shares of restricted stock that do not vest are subject to forfeiture. In September 2020, we granted 123,501 RSAs outside of our 2020 Plan, 98,450 of which were fully vested on the date of grant and the remainder of which vested in January 2021. In December 2020, we granted 12,000 RSAs outside of our 2020 Plan, all of which were fully vested on the date of grant. There were no RSAs outstanding as of March 31, 2021 and no RSA activities during the three and six months ended September 30, 2021.

Restricted Stock Units

RSUs are grants of shares of our common stock that vest in accordance with terms and conditions established by the administrator of the 2020 Plan. Subject to the provisions of the 2020 Plan, the administrator determines the terms and conditions of RSUs, including the vesting criteria. We granted 816,180 RSUs during the three months ended September 30, 2020, 4,000 of which were fully vested on the date of grant. The remainder of the RSUs are scheduled to vest as follows: one third will vest on each of January 1, 2022, January 1, 2023 and July 1, 2023, in each case subject to the RSU holders’ continued status as a service provider to the Company through each vesting date. We granted 137,452 RSUs during the three months ended March 31, 2021, which are scheduled to vest in various periods, beginning immediately and ending on February 2025, in each case subject to the RSU holders’ continued status as a service provider to the Company through each vesting date. We granted 35,000 RSUs during the three months ended September 30, 2021, 25 percent of which are scheduled to vest after one year and the remainder are scheduled to vest each quarter for three years, in each case subject to the RSU holders’ continued status as a service provider to the Company through each vesting date.

On October 4, 2021, the Company also issued to Yaskawa a warrant to purchase up to 650,000 shares of common stock at an exercise price of $6.00 per share. The warrant has a term of three years (subject to earlier termination as set forth therein), provides for a cashless exercise feature and is immediately exercisable.

Private Placement of Common Stock and Warrants

Between November 5, 2021 and November 9, 2021, the Company entered into a series of securities purchase agreements (each, a “Purchase Agreement”) with accredited investors (the “Purchasers”), including the Company’s largest stockholder, pursuant to which the Company issued and sold to the Purchasers (i) an aggregate of 6,600,000 shares of common stock at a purchase price of $5.00 per share (the “First Closing Shares”) and (ii) warrants to purchase an aggregate of 1,375,001 shares of common stock (the “First Closing Warrants”), for aggregate gross proceeds of $33.0 million (the “Private Placement”). After payment of placement agent cash fees and expenses of the Private Placement, the Company received net proceeds of approximately $32.2 million. The First Closing Warrants have an exercise price of $6.00 per share, provide for a cashless exercise feature, and are exercisable until the third anniversary of the date of issuance.

Pursuant to the Purchase Agreements, during the Second Investment Period (as described below), each Purchaser has the right (but not the obligation) (an “Option”), subject to the satisfaction of customary closing conditions, to purchase and acquire from the Company (i) additional shares of common stock at a purchase price of $5.00 per share (the “Second Closing Shares”) and (ii) additional warrants to purchase shares of common stock (the “Second Closing Warrants” and together with the First Closing Warrants, the “Warrants”). If and when issued, the Second Closing Warrants would have an exercise price of $6.00 per share, provide for a cashless exercise feature, and be exercisable until the third anniversary of the date of issuance of the First Closing Warrants. If the Options are exercised in full, the maximum number of Second Closing Shares and Second Closing Warrants that may be issued by the Company is 3,299,999 shares of common stock and warrants to purchase 687,501 shares of common stock.

As set forth in the Purchase Agreements, the “Second Investment Period” begins on the date of the applicable Purchase Agreement and ends on the earliest to occur of: (i) the third anniversary of the applicable agreement; (ii) a Change in Control (as defined in the Purchase Agreements), provided that the Company has given the Purchaser at least 10 days’ prior written notice of such Change in Control; (iii) the tenth day after disclosure to the Purchaser of a Change in Control, but only if the Company has not given prior written notice of such Change in Control to the Purchaser in accordance with clause (ii); or (iv) the 90th day following the later of (A) the date on which a registration statement registering the resale of the First Closing Shares and the shares of Common Stock issuable upon exercise of the First Closing Warrants is declared effective by the Securities and Exchange Commission, or (B) the date on which the Company’s common stock is first listed on Nasdaq.

Business and Basis of Presentation (Policies)

6 Months Ended

Sep. 30, 2021

Accounting Policies [Abstract]

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Parent and its wholly-owned subsidiaries, Transphorm Technology, Transphorm Japan, Inc., Transphorm Japan Epi, Inc. and Transphorm Aizu, Inc. Upon consolidation, all significant intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management bases its estimates and assumptions on historical experience, knowledge of current conditions, and its belief of what could occur in the future, given available information. Actual results could differ from those estimates, and such differences could be material to the consolidated financial statements. Estimates are used for, but not limited to, the determinations of fair value of stock awards and promissory notes, accrual of liabilities, revenue recognition, inventory reserve, and useful lives for property and equipment.

Cash and Cash Equivalents

The Company considers all highly-liquid investments with original maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist principally of bank deposits and money market funds.

Foreign Currency Risk

The Company is exposed to foreign currency risk due to its operations in Japan (Yen). Assets and liabilities of the operations are re-measured into U.S. currency at exchange rates in effect at the balance sheet dates through the consolidated statements of comprehensive income. Gains or losses resulting from foreign currency transactions are re-measured using the rates on the dates on which those elements are recognized during the period and are included in other income or expense in the consolidated statements of operations.

Concentrations of Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company is exposed to credit risk in the event of default by the financial institution holding its cash. The Company’s investment policy restricts investments to high-quality investments and limits the amounts invested with any one issuer, industry or geographic area. Risks associated with cash holdings in excess of insured limits are mitigated by banking with high-quality institutions. To date, the Company has not experienced any significant losses on its cash and cash equivalents. The Company periodically evaluates the relative credit standing of these financial institutions.The Company is subject to risks common in the power conversion components industry, including, but not limited to, technological obsolescence, dependence on key personnel, market acceptance of its products, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed.

Comprehensive Loss

Comprehensive loss is comprised of net loss and other comprehensive income (loss). Other comprehensive income (loss) includes the impact of foreign currency translation adjustments.

Accounts Receivable

Accounts receivable are analyzed and allowances for uncollectible accounts are recorded, as required. Provisions for uncollectible accounts, if any, are recorded as bad debt expense and included in general and administrative expenses in the accompanying consolidated statements of operations. The process for determining the appropriate level of allowances for doubtful accounts involves judgment, and the Company considers such factors as the age of the underlying receivables, historical and projected collection trends, the composition of outstanding receivables, current economic conditions and regulatory changes. An account is fully reserved when reasonable collection efforts have been unsuccessful and it is probable that the receivable will not be recovered.

Inventory

Inventory is stated at the lower of cost (first-in, first-out method) or net realizable value. The Company periodically reviews the value of items in inventory and records write-downs or write-offs based on its assessment of slow moving or obsolete inventory. The Company maintains an inventory reserve for obsolete inventory and generally makes inventory value adjustments against the inventory reserve.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is determined using the straight-line method over the estimated useful lives of the respective assets, generally ranging from three to seven years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the related lease term. Depreciation for equipment commences once it is placed in service, and depreciation for buildings and leasehold improvements commences once they are ready for their intended use. The Company expenses maintenance and repair costs that do not extend the life of the asset as they are incurred.

Property and Equipment, Impairment

The Company evaluates the carrying amount of its property and equipment whenever events or changes in circumstances indicate that the assets may not be recoverable. An impairment loss would be recognized when estimated future cash flows expected to result from the use of an asset or asset group and its eventual disposition are less than the carrying amount of the asset or asset group.

Goodwill

Goodwill arose for the acquisition of a business in February 2014 based in Japan and was accounted for as the purchase of a business. Goodwill generated from business combinations and deemed to have indefinite lives are not subject to amortization and instead are tested for impairment at least annually in December unless certain events occur or circumstances change. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. We test for goodwill impairment annually or earlier if events or changes in circumstances indicate goodwill might possibly be impaired. Impairment exists when the carrying value of the goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to that excess as a charge to operations in the unaudited condensed consolidated statements of operations.

Intangible Assets

Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives, which generally range from three to ten years. Each reporting period, the Company evaluates the estimated remaining useful lives of intangible assets and whether events or changes in circumstances warrant a revision to the remaining periods of amortization.If it is determined that the carrying values might not be recoverable based upon the existence of one or more indicators of impairment, the Company performs a test for recoverability using various methodologies, such as the income approach or cost approach, to determine the fair value of intangible assets depending upon the nature of the assets. If assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds their respective fair values.

Revenue Recognition

The Company derives its revenues from sales of high-powered GaN-based products manufactured utilizing the Company’s proprietary and patented epiwafer technology and wafer fabrication and other assembly processes, sales of GaN epiwafers for the radio frequency (“RF”) and power markets, and sales of licenses to use such patented proprietary technology, as well as enabling EPI wafer growth services and products to our strategic partners. Revenues are recognized when control of these products or licenses are transferred to the Company’s customers in an amount that reflects the consideration it expects to be entitled to in exchange for those products and licenses. Sales and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. The Company does not have any significant financing components associated with its revenue contracts, as payment is received at or shortly after the point of sale.

Disaggregation of Revenue from Contracts with Customers

Revenue consists of licensing revenue, government contract revenue from our contract with the U.S. Navy and product sales, with applicable performance obligations satisfied at a point in time. Products are sold to distributors and end-users in various sectors such as, but not limited to, the automotive, gaming, industrial, IT, and consumer products industries.

As part of the multi-element commercial arrangement executed with Nexperia on April 4, 2018 (see Note 2 - Nexperia Arrangement), the Company agreed to grant Nexperia the perpetual exclusive right to use the Company’s existing Gen-3 manufacturing process technology. License fees are received upon satisfaction of contractual milestones and recognized upon delivery of the perpetual license or transferred technology without any remaining performance obligations. The Company recognized $8.0 million of licensing revenue for the three and six months ended September 30, 2021, and $0 and $5.0 million of licensing revenue for the three and six months ended September 30, 2020, respectively.

In December 2020, we entered into a cooperation and development agreement with Yaskawa Electric Corporation (“Yaskawa”), pursuant to which Yaskawa agreed to provide $4.0 million over approximately three years to fund development activities related to industrial power conversion applications, with an initial focus on servo motor drive applications. Yaskawa provided payments of $1.0 million and $750 thousand of this $4.0 million commitment in December 2020 and July 2021, respectively. The Company evaluated and concluded that the deliverables are the same and nature of the services to be provided to Yaskawa will be consistent over the period of approximately three years. Accordingly, with respect to the $1.0 million payment, the Company recognized $333 thousand as revenue in each of the three months ended December 31, 2020, March 31, 2021 and June 30, 2021

and, with respect to the $750 thousand payment, the Company recognized $375 thousand as revenue for the three months ended September 30, 2021.

Government contract revenues are principally generated under research and development contracts. Contract revenues are derived primarily from research contracts with agencies of the U.S. government. We believe credit risk related to accounts receivable arising from such contracts is minimal. These contracts may include cost-plus fixed fee and fixed price terms. All payments to us for work performed on contracts with agencies of the U.S. government are subject to adjustment upon audit by the Defense Contract Audit Agency. The Company received new government authorized rates for billing purposes which allowed for retroactive application since inception. The cumulative impact of this rate change as of September 30, 2021 was $423 thousand, of which $(83) thousand and $505 thousand were recorded in the three months ended March 31, 2021 and September 30, 2020, respectively. The Company will use the new approved rates on a go-forward basis.

Performance Obligations

For performance obligations related to the sale of products, control transfers to the customer at a point in time. The Company’s principal terms of sale are free on board shipping or destination and the Company transfers control and records revenue for product sales upon shipment or delivery to the customer, respectively. For performance obligations related to the licensing of patented technology in perpetuity, control also transfers to the customer at a point in time. The Company transfers control and records revenue for licensing fees once the Company has (i) provided or otherwise makes available the patented technology to the customer and (ii) the customer is able to use and benefit from the patented technology.

Variable Consideration

The nature of the Company’s arrangement with Nexperia gives rise to variable consideration in the form of milestone and royalty payments. The royalties qualify for the sales and usage-based royalty exception, as the license of intellectual property is the predominant item to which the royalty relates and are recognized upon the subsequent sale occurring. The variable amounts are received upon satisfaction of contractually agreed upon development targets and sales volume.

Research and Development

The Company is a party to research grant contracts with the U.S. government for which the Company is reimbursed for specified costs incurred for its research projects. These projects include energy saving initiatives for which the U.S. government offers reimbursement funds. Such reimbursements are recorded as an offset to research and development expenses when the related qualified research and development expenses are incurred. Reimbursable costs are recognized in the same period the costs are incurred up to the limit of approved funding amounts on qualified expenses.

Stock-based compensation expense

All share-based payments, including grants of stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), are measured at the fair value of the share-based awards on the grant date and recognized over their respective vesting periods, which is generally one to four years. The estimated fair value of stock options at the grant date is determined using the Black-Scholes-Merton pricing model. The RSAs and RSUs are measured using the estimated fair value of the stock price, which, due to limited trading history, is based on recent equity sales. The Company recognizes the fair value of share-based payments as compensation expense for all expected-to-vest stock-based awards over the vesting period of the award using the straight-line attribution or graded vesting method provided that the amount of compensation cost recognized at any date is no less than the portion of the grant-date fair value of the award that is vested at that date.

The Black-Scholes-Merton option pricing model requires inputs such as the fair value of common stock on date of grant, expected term, expected volatility, dividend yield, and risk-free interest rate. Further, the forfeiture rate also affects the amount of aggregate compensation expense. These inputs are subjective and generally require significant analysis and judgment to develop. Volatility data is obtained from a study of publicly traded industry peer companies. The forfeiture rate is derived primarily from the Company’s historical data, and the risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues commensurate with the expected term. Management generally uses the simplified method to calculate the expected term for employee grants as the Company has limited historical exercise data or alternative information to reasonably estimate an expected term assumption. The simplified method assumes that all options will be exercised midway between the weighted average vesting date and the contractual term of the option.

Stock-based compensation expense recognized in the Company’s unaudited condensed consolidated financial statements is based on awards that are expected to vest. These expense amounts have been reduced by using an estimated forfeiture rate. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company evaluates the assumptions used to estimate forfeitures annually in connection with the recognition of stock-based compensation expense.

Stock-based compensation expense is determined based on the fair value of the Company’s common stock as determined by the Board of Directors and assumptions such as volatility, expected term, risk-free interest rates, and other factors. Changes in the deemed fair value of the common stock, the underlying assumptions in the calculations, the number of options granted or the terms of such options, the expected forfeiture rate, the treatment of tax benefits and other changes may result in significant differences in the amounts or timing of the compensation expense recognized. The assumptions and estimates are made as follows:

•Expected Volatility - The Company utilizes the historical volatility of representative public companies to determine its expected volatility, as the trading history of the Company’s common stock is limited.

•Estimated Forfeitures - The Company adopted ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting and has elected to account for forfeitures as they occur and therefore, stock-based compensation expense has been calculated based on actual forfeitures in the statements of operations, rather than our previous approach which was net of estimated forfeitures. The net cumulative effect of this change was not material.

•Expected Dividend Yield - The Company has not issued any common stock dividends; therefore, a dividend yield of zero was used.

•Risk-Free Interest Rate - The Company bases the risk-free interest rate used in the Black-Scholes-Merton option pricing model on the implied yield currently available on United States Treasury zero-coupon issues with an equivalent expected term.

•Expected Term - The expected term of stock options represents the period that the Company’s stock options are expected to be outstanding. The Company generally uses the simplified method to calculate the expected term for employee grants.

Loss Per Share

Basic income (loss) per share is calculated by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is calculated by dividing the net loss attributable to common stockholders by the sum of the weighted average number of common shares outstanding plus potential dilutive common shares outstanding during the period. Potential dilutive securities, comprised of stock warrants, restricted stock units and stock options, are not reflected in diluted income (loss) per share because such shares are anti–dilutive. Dilutive impact of potential common shares resulting from common stock equivalents is determined by applying the treasury stock method.

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The carrying values of the Company’s financial instruments such as cash equivalents, accounts receivable, revolving credit facility, accounts payable and accrued liabilities approximate fair values due to the short-term nature of these items. The Company has elected the fair value option for its promissory notes.

Income Taxes

The Company accounts for income taxes in accordance with Accounting Standards Codification (“ASC”) 740, Income Taxes (“ASC 740”). ASC 740 prescribes the use of the liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted statutory tax rates in effect at the balance sheet date. The Company records a valuation allowance to reduce its deferred tax assets when uncertainty regarding their realizability exists.

Equity Method Investments

The Company uses the equity method to account for investments in entities that it does not control, but in which it has the ability to exercise significant influence over operating and financial policies. The Company's proportionate share of the net income or loss of these companies is included in consolidated net loss. Judgments regarding the level of influence over each equity method investment include consideration of key factors such as the Company's ownership interest, representation on the board of directors or other management body and participation in policy-making decisions.

Segment Reporting

The Company’s operations and its financial performance is evaluated on a consolidated basis by the chief operating decision maker. The Company’s chief operating decision maker is the Parent’s Chief Executive Officer. Accordingly, the Company considers all of its operations to be aggregated in one reportable operating segment.

Recently Issued Accounting Standards under Evaluation

Recently Issued Accounting Standards under Evaluation

Debt - In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, to address the complexity in accounting for certain financial instruments with characteristics of liabilities and equity. Amongst other provisions, the amendments in this ASU significantly change the guidance on the issuer’s accounting for convertible instruments and the guidance on the derivative scope exception for contracts in an entity’s own equity such that fewer conversion features will require separate recognition, and fewer freestanding instruments, like warrants, will require liability treatment. Refer to our white paper, Accounting simplifications for convertible instruments and warrants, for additional information. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Leases - In June 2020, the FASB issued ASU 2020-05, which amends the effective dates of the FASB’s standards on leasing (ASC 842) to give immediate relief to certain entities as a result of the widespread adverse economic effects and business disruptions caused by the COVID-19 pandemic. In February 2016, the FASB issued ASU 2016-02, Leases, which, for operating leases, requires the lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, on its balance sheet. The guidance also requires a lessee to recognize single lease costs, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. The leasing standard’s effective dates were the fiscal year beginning after December 15, 2019 as originally issued (ASU 2016-02) and the fiscal year beginning after December 15, 2020 as amended by ASU 2019-10. As amended by ASU 2020-05, the leasing standard’s effective date is now the fiscal year beginning after December 15, 2021. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Financial Instruments - FASB ASU 2020-03, Codification Improvements to Financial Instruments, makes clear the determination of the contractual life of a net investment in leases in estimating expected credit losses under ASC 326, Financial Instruments – Credit Losses. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when

such losses are recorded. ASU 2016-13 is effective for the Company in 2023. Early adoption is permitted. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Income Tax - In December 2019, the FASB issued ASU 2019-12, which modifies ASC 740 to simplify the accounting for income taxes. The ASU’s amendments are based on changes that were suggested by stakeholders as part of the FASB’s simplification initiative (i.e., the FASB’s effort to reduce the complexity of accounting standards while maintaining or enhancing the helpfulness of information provided to financial statement users). ASU 2019-12 is effective for fiscal years beginning after December 15, 2022. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.
