These forward-looking statements are based on Management’s current knowledge and belief and include information concerning the Company’s possible or assumed future financial condition and results of operations. A number of factors, some of which are beyond the Company’s ability to predict or control, could cause future results to differ materially from those contemplated.

Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations. The reader is directed to the Company's annual report on Form 10-K for the year ended March 26, 2022 for further discussion of factors that could affect the Company's business and cause actual results to differ materially from those expressed in any forward-looking statement made in this report.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization and Significant Accounting Policies

The unaudited condensed consolidated financial statements included herein have been prepared by Giga-tronics Incorporated (“Giga-tronics,” “Company,” or “we”), pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the fiscal year. In the opinion of management, the information contained herein reflects all adjustments (consisting of normal recurring entries) necessary to make the consolidated results of operations for the interim periods a fair statement of such operations. Please refer to the Company’s Annual Report on Form 10-K for the year ended March 26, 2022 for a discussion of our significant accounting policies. During the three months ended June 26, 2022, there were no material changes to these policies other than as disclosed below. For further information, refer to the consolidated financial statements and footnotes thereto, included in the Annual Report on Form 10-K, filed with the SEC for the year ended March 26, 2022.

Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of Giga-tronics and its wholly owned subsidiary, Microsource, Inc. (“Microsource”). All significant intercompany balances and transactions have been eliminated in consolidation.

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

Note 2. Going Concern and Management’s Plan

The Company incurred net losses of $1.2 million in the first quarter ended June 25, 2022 and $2.7 million in the fiscal year ended March 26, 2022. These losses have contributed to an accumulated deficit of $35.2 million as of June 25, 2022.

On December 27, 2021, Giga-tronics entered into a Share Exchange Agreement with BitNile Holdings, Inc. ("BitNile") and Gresham Worldwide, Inc. (“Gresham”), which is a wholly-owned subsidiary of BitNile (the “Share Exchange Agreement”). Under the Share Exchange Agreement, the Company is restricted from raising funds either via debt or equity and has therefore received a loan of $1.3 million from Digital Power Lending, LLC, (“DPL”) which is an affiliate of BitNile. The Company expects to complete the merger with Gresham in September 2022 and resolve the going concern matter (See Note 18 - Share Exchange Agreement with BitNile and Gresham).

Management has also put in place a plan as a stand-alone company and believes that the Company can repay the loan to BitNile in November 2022 without raising additional funding because of the large inventory on hand for the Threat Emulation System ("TEmS") solution, which will result in cash with sales of the TEmS solution. Management will continue to review all aspects of its business including, but not limited to, the contribution of its individual business segments, in an effort to improve cash flow and reduce costs and expenses, while continuing to invest, to the extent possible, in new product development for future revenue streams.

The Company's historical operating results and forecasting uncertainties indicate that substantial doubt exists related to its ability to continue as a going concern. Management believes that through the actions to date and possible future actions described above, the Company should have the necessary liquidity to continue operations for at least twelve months from the issuance of the financial statements. However, management cannot predict, with certainty, the outcome of its actions to maintain or generate additional liquidity, including the availability of additional financing, or whether such actions would generate the expected liquidity as currently planned. Forecasting uncertainties also exist with respect to the Electronic Warfare ("EW") test system product line due to the potential longer than anticipated sales cycles.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern and do not include any adjustments that might result if the Company were unable to do so.

Note 5. Financed Receivables

On March 11, 2019, the Company entered into an Amended and Restated Business Financing Agreement (“Restated Financing Agreement”) with Western Alliance Bank, as successor to Bridge Bank.

Under the Restated Financing Agreement, Western Alliance Bank may advance up to 85% of the amounts of invoices issued by the Company up to a maximum of $2.5 million in aggregate advances outstanding at any time.

Under the Restated Financing Agreement, interest accrues on outstanding amounts at an annual rate equal to the greater of prime or 4.5% plus one percent. The Company is required to pay certain fees, including an annual facility fee of $14,700 that is paid in two equal semi-annual installments. The Company’s obligations under the Restated Financing Agreement are secured by a security interest in substantially all of the assets of the Company and any domestic subsidiaries, subject to certain customary exceptions. The Restated Financing Agreement has no specified term and may be terminated by either the Company or Western Alliance Bank at any time.

As of June 25, 2022, and March 26, 2022, the Company’s total outstanding borrowings under the Restated Financing Agreement were $1,203,000 and $450,000, respectively, and are included in Loans payable, net of discounts and issuance costs on the unaudited condensed consolidated Balance Sheets.

Note 6. Term Loan

On November 12, 2021, the Company borrowed $500,000 from DPL and an affiliate of BitNile, a Delaware corporation. On January 7, 2022, the Company borrowed an additional $300,000 from DPL.

On April 5, 2022, the Company (1) borrowed an additional $500,000 from DPL, (2) amended its Share Exchange Agreement and issued a warrant to Gresham. The Share Exchange Agreement and the warrant issued to Gresham are described in Note 18 – Share Exchange Agreement with BitNile and Gresham.

The loan is evidenced by a secured promissory note dated April 5, 2022 that provides, among other things that the principal amount of the loan will bear interest at the rate of 10.0% per annum. Unless prepaid by the Company, all principal and accrued interest under the loan is payable on November 12, 2022 or, if earlier, upon the Company’s completion of an underwritten public offering or the

9

termination of the Share Exchange Agreement. The Company’s obligations under the loan are secured by a pledge of all of the Company’s assets. The loan and the lender’s security interest are subordinate to the Company’s existing bank lending arrangement.

As of June 25, 2022, and March 26, 2022, the Company’s total outstanding loan balance was $1,300,000 and $800,000, respectively, and are included in Loans payable, net of discounts and issuance costs on the unaudited condensed consolidated Balance Sheets.

On April 5, 2022, the Company borrowed an additional $500,000 from DPL and the Company and DPL entered into an Amended and Restated Secured Promissory Note and an amendment to the Security and Pledge Agreement originally dated as of November 12, 2021 to reflect that the Company has borrowed an aggregate of $1,300,000 from DPL. The Company intends to use the additional loan proceeds for general corporate purposes. The other material terms of the Loan remain unchanged.

This description is qualified by the Amended and Restated Secured Promissory Note, the Security and Pledge Agreement with DPL and the amendment thereto, copies of which are filed as exhibits to this report and incorporated by reference herein.

Note 7. Employee Retention Credit under the CARES Act

In August 2021, the Company applied for the Employee Retention Credit (“ERC”) for a total amount of $233,000. This ERC is a fully refundable tax credit for employers equal to 50 percent of qualified wages that eligible employers pay their employees. This ERC applies to qualified wages paid after March 12, 2020 and before January 1, 2021.

In January 2022, the Company applied for another ERC for a total amount of $321,000. This ERC is a fully refundable tax credit for employers equal to 70 percent of qualified wages that eligible employers pay their employees. This ERC applies to qualified wages paid after December 2020 and before January 1, 2022.

Currently, we are unable to provide an estimate as to whether and when we will receive these ERC funds as the Company's applications are pending Internal Revenue Service processing and approval.

Note 8. Leases

Operating leases

The Company has a non-cancelable operating lease for office, research and development, engineering, laboratory, storage and warehouse uses in Dublin, California for 77 months from April 1, 2017 through August 31, 2023. The Company agreed to pay an aggregate base rent of $2,384,913 for the period of 77 months, with an annual increase of $0.05 per rentable square foot for each subsequent year. The lease provided for rent abatement of $173,079 during the initial five months of the lease term, subject to the Company performing the terms and conditions required under the lease, and certain tenant improvements completed at the landlord’s expense of $358,095.

In December 2018, the Company entered into a lease agreement for an additional 1,200 square foot facility for certain engineering personnel located in Nashua, New Hampshire, which began on February 1, 2019. Effective March 1, 2020, we amended and replaced in its entirety the original Nashua lease agreement to increase the facility size to 2,400 square feet and extend its expiration to February 28, 2023.The monthly payment for fiscal year 2022 and fiscal year 2023 under the amended agreement is $2,500.

Per the terms of the Company’s lease agreements, the Company does not have any residual value guarantees. In calculating the present value of the lease payments, the Company has elected to utilize its incremental borrowing rate. The Company has elected for facility operating leases to not separate each lease component from its associated non-lease components. The building lease includes variable payments (i.e., common area maintenance) which are charged and paid separately from rent based on actual costs incurred and therefore are not included in the right-of-use asset and liability but reflected in operating expense in the period incurred.

Note 9. Fair Value Measurement

Accounting Standards Codification ("ASC") 820 “Fair Value Measurements” ("ASC 820") defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. ASC 820 defines fair value 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. ASC 820 establishes a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

The three levels of the fair value hierarchy under ASC 820 are described below:

•Level 1 —Valuations are based on quoted prices in active markets for identical assets or liabilities and readily accessible by us at the reporting date. Examples of assets and liabilities utilizing Level 1 inputs are certain money market funds, U.S. Treasuries and trading securities with quoted prices in active markets.

•Level 2 —Valuations based on inputs other than the quoted prices in active markets that are observable either directly or indirectly in active markets. Examples of assets and liabilities utilizing Level 2 inputs are U.S. government agency bonds, corporate bonds, commercial paper, certificates of deposit and over-the-counter derivatives.

•Level 3 —Valuations based on unobservable inputs in which there is little or no market data, which require us to develop our own assumptions.

In determining the fair value of warrants, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value.

Upon issuance on April 5, 2022 and at June 25, 2022 the warrant issued in connection with loan from DPL was measured at fair value (See Note 18 - Share Exchange Agreement with BitNile and Gresham).

The Company’s fair value hierarchies for its financial assets and liabilities which require fair value measurement on a recurring basis are as follows:

(In thousands)	Level 1		Level 2		Level 3		Total
Balance at March 26, 2022
Liabilities
Warrant liability for warrant issued in connection with loan from DPL	$	—	$	—	$	—	$	—
Balance at June 25, 2022
Liabilities
Warrant liability for warrant issued in connection with loan from DPL	$	—	$	—	$	24	$	24

During the three months ended June 25, 2022 and the year ended March 26, 2022, there were no transfers between Level 1, Level 2, or Level 3 assets or liabilities reported at fair value and the valuation techniques used did not change compared to the Company’s established practice.

11

The fair value of the warrant issued in connection with loan from DPL has been determined using Black-Scholes-Merton model. The Company’s common stock fair value is a significant Level 3 input affecting the valuation of the warrant.

Balance at June 25, 2022	$	24

Upon issuance on April 27, 2021, the prefunded warrants liability was measured at fair value. On July 28, 2021, the Company and the holder amended the terms of the Prefunded Warrants to restrict the holder’s option to require cash payment at the Black-Scholes-Merton model value of the remaining unexercised portion of the holder’s Prefunded Warrants to only Fundamental Transactions that are within the Company’s control. Because of this modification of the put-option provision, the Prefunded Warrants are no longer required to be classified as a liability under either ASC 480, "Distinguishing Liabilities from Equity", or ASC 815, "Derivatives and Hedging", guidance and do not include any embedded features that require bifurcation. Therefore, the Prefunded Warrants liability were remeasured on the modification date and reclassified to equity (See Note 10 – Sale of Common Stock and Prefunded Warrants). As of June 25, 2022 and March 26, 2022, the prefunded warrants liability was $0.

There were no assets measured at fair value on a recurring basis and there were no assets measured at fair value on a non-recurring basis as of June 25, 2022 and March 26, 2022. There were no liabilities measured at fair value on a recurring or non-recurring basis at March 26, 2022.

Note 10. Sale of Common Stock and Prefunded Warrants

On April 27, 2021, the Company entered into a Securities Purchase Agreement (“Purchase Agreement”) with certain accredited investors (“Investors”) pursuant to which it issued and sold prefunded warrants to purchase an aggregate of 461,538 shares of the Company’s common stock (“Prefunded Warrants”) for gross proceeds of $1,500,000 or $3.25 per Prefunded Warrant in a private placement on the same day. Net proceeds to the Company after fees and expenses of the private placement were approximately $1,343,000. The Purchase Agreement contains customary representations and warranties of the Company and certain indemnification obligations and ongoing covenants of the Company.

The Prefunded Warrants are immediately exercisable and may be exercised for a de-minimis exercise price of $0.01 per share subject to the limitation that a holder of a Prefunded Warrant will not have the right to exercise any portion of the Prefunded Warrant if the holder together with its affiliates and attribution parties (as such terms are defined in the Prefunded Warrants) would beneficially own in excess of 9.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Prefunded Warrants. The Prefunded Warrants do not expire. The Prefunded Warrants also contained a put option, exercisable under certain conditions. Because of this put-option provision, the Prefunded Warrants were initially classified as a liability at fair value of $1,703,000 on the issuance date and marked to market at each reporting date. Further, because the fair value of the prefunded warrant liability on the issuance date was greater than the proceeds of the Prefunded Private Placement and the warrants were issued to existing common stockholders, the difference was recorded to accumulated deficit as a $203,000 deemed dividend. There were finance costs of $157,000 associated with the issuance of the Prefunded Warrants. There was a gain on measurement of $46,000 on the prefunded warrant liability in the first quarter of fiscal 2022 and $46,000 in the second quarter of fiscal 2022.These amounts are recorded in “Other income (expense), net” in the unaudited condensed consolidated Statements of Operations.

Pursuant to the terms of the Purchase Agreement, and as a condition to closing the private placement, the Company and each Investor simultaneously entered into a registration rights agreement (“Registration Rights Agreement”) requiring the Company to file a registration statement with the SEC within 45 days of the closing of the private placement to register for resale the shares of the Company’s common stock underlying the Prefunded Warrants. The Registration Rights Agreement contains customary terms and conditions, certain liquidated damages provisions for failing to comply with the timing obligations for the filing and effectiveness of the registration statement, and certain customary indemnification obligations.

On April 27, 2021, in connection with the private placement, the Company issued warrants to purchase 23,076 shares of the Company’s common stock to the placement agent for such offering (“Placement Agent Warrants”). The Placement Agent Warrants have an exercise price per share equal to $3.575, subject to adjustment in certain circumstances, and will expire on April 27, 2026. The Placement Agent Warrants do not have the same put option provision as the original Prefunded Warrants and, therefore, are classified as equity.

12

On June 6, 2021, the Company entered into a Securities Purchase Agreement with a private investor for the sale of a total of 46,154 common shares at the price of $3.25 per share, for aggregate gross proceeds of $150,000. The sale was completed, and the shares of common stock were issued on June 6, 2021. Net proceeds to the Company after fees and expenses of the transaction were approximately $145,000 (See Note 16 - Preferred Stock and Warrants).

On July 28, 2021, the Company and the holder amended the terms of the Prefunded Warrants to restrict the holder’s option to require cash payment at the Black-Scholes-Merton value of the remaining unexercised portion of the holder’s Prefunded Warrants to only Fundamental Transactions that are within the Company’s control. Because of this modification of the put-option provision, the Prefunded Warrants are no longer required to be classified as a liability under either ASC 480, "Distinguishing Liabilities from Equity", or ASC 815, "Derivatives and Hedging", guidance and do not include any embedded features that require bifurcation. Therefore, the Prefunded Warrants liability were remeasured on the modification date of July 28, 2021 and reclassified to equity as of that date.

Note 11. Net Loss Per Share

Basic loss per share is calculated by dividing net loss by the weighted average common shares outstanding during the period. Diluted earnings per share (“EPS”) reflects the net incremental shares that would be issued if unvested restricted shares became vested and dilutive outstanding stock options and warrants were exercised, using the treasury stock method. In addition, certain options are considered anti-dilutive because assumed proceeds from exercise price, related tax benefits and average future compensation was greater than the weighted average number of options outstanding multiplied by the average market price during the period.

Shares excluded from the diluted EPS calculation for the three month periods ended June 25, 2022 and June 26, 2021 are as follows (In thousands):

Anti-dilutive securities	June 25, 2022		June 26, 2021
Common shares issuable upon exercise of stock options		335		378
Restricted stock awards		30		15
Common shares issuable upon conversion of convertible preferred stock		157		157
Common shares issuable upon exercise of warrants		530		530

(In thousands except per share data)	Three Months Ended
	June 25, 2022			June 26, 2021
Net loss attributable to common shareholders	$	(1,248	)	$	(860	)
Weighted-average basic and diluted common shares outstanding		2,777			2,725
Net loss per common share attributable to common shareholder – basic and diluted	$	(0.45	)	$	(0.32	)

There were no dilutive securities in the three months ended June 25, 2022 and June 26, 2021 because the stock options, restricted stock awards, convertible preferred stocks and warrants were all anti-dilutive.

Note 12. Stock-based Compensation and Employee Benefit Plans

The Company maintains a 2018 Equity Incentive Plan which provides for the issuance of up to 416,667 shares of common stock upon the exercise of options, stock awards and grants. With the adoption of the 2018 Equity Incentive Plan, no further awards will be issued under the Company’s 2005 Equity Incentive Plan, though all awards under the 2005 Equity Incentive Plan that are outstanding continue to be governed by the terms, conditions and procedures set forth in the plan and any applicable award agreement.

During the first quarter of fiscal year 2023, the Company did not grant any stock options. The vested portion of all option grants may be exercised only while the grantee is employed by the Company (or while providing services under a service arrangement in the case of non-employees) or within a certain period after termination of employment or service arrangement in the case of non-employees. Options granted to employees shall not have terms in excess of 10 years from the grant date. Holders of options may be granted stock appreciation rights (“SARs”), which entitle them to surrender outstanding awards for a cash distribution under certain changes in ownership of the Company, as defined in the stock option plan. As of June 25, 2022, and March 26, 2022, no SARs have been granted under any option plan.

As of June 25, 2022, there were 91,114 shares of common stock available for issuance of additional awards under the 2018 Equity Incentive Plan. The Company records compensation cost associated with stock-based compensation equivalent to the estimated fair value of the awards over the requisite service period.

13

Stock Options

In calculating compensation related to stock option grants, the fair value of each stock option was estimated on the date of grant using the Black-Scholes-Merton model and the following weighted average assumptions:

Description	Three Months Ended
	June 25, 2022			June 26, 2021
Dividend yield		—			—
Expected volatility		—	%		107.00	%
Risk-free interest rate		—	%		0.82	%
Expected term (years)		—			5.50

The computation of expected volatility used in the Black-Scholes-Merton model is based on the historical volatility of the Company’s share price. The expected term is estimated based on a review of historical employee exercise behavior with respect to option grants. The risk-free interest rate is based on the U.S. Treasury rates with maturity similar to the expected term of the option on the date of grant. No options were granted during for three month period ended June 25, 2022.

A summary of the changes in stock options outstanding for the three months period ended June 25, 2022 is as follows:

Description	Shares			Weighted Average Price per share		Weighted Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value
Outstanding at March 26, 2022		353,037		$	4.75		7.26	$	—
Forfeited / Expired		(17,836	)		5.22		—		—
Outstanding at June 25, 2022		335,201		$	4.73		7.01	$	—
Exercisable at June 25, 2022		285,028		$	4.85		6.79	$	—
Expected to vest in the future		50,173		$	4.03		8.23	$	—

As of June 25, 2022, there was $341,000 of total unrecognized compensation cost related to non-vested options. The cost is expected to be recognized over a weighted average period of 2.19 years and will be adjusted as forfeitures occur. There were no options exercised in the three-month periods ended June 25, 2022 and June 26, 2021. Share based compensation cost related to stock options recognized in operating results for the three months ended June 25, 2022 and June 26, 2021 totaled $31,000 and $129,000, respectively.

Restricted Stock

The Company granted 10,000 Restricted Stock Awards (“RSAs”) during the first quarter of fiscal 2023 and 0 RSAs during the first quarter of fiscal 2022. RSAs are considered fixed awards as the number of shares and fair value at the grant date is amortized over the requisite service period and will be adjusted as forfeitures occur.

As of June 25, 2022, there was $41,000 of total unrecognized compensation cost related to non-vested RSAs. That cost is expected to be recognized over a weighted average period of 1.08 years and will be adjusted for subsequent changes in estimated forfeitures. Compensation cost recognized for RSAs for the three months ended June 25, 2022 and June 26, 2021 totaled $21,000 and $26,000, respectively.

A summary of the changes in non-vested RSAs outstanding for the three month period ended June 25, 2022 is as follows:

Restricted Stock Awards	Shares		Weighted Average Grant Date Fair Value
Non-vested at March 26, 2022		20,020	$	3.65
Granted		10,000		1.75
Non-vested at June 25, 2022		30,020	$	3.02

Note 13. Significant Customer and Industry Segment Information

The Company has two reportable segments: Microsource and the Giga-tronics Division. Microsource’s primary business is the design of custom Microwave Integrated Components (“MIC”) as well as the production of MIC components using chip and wire assembly methods. Microsource offers a line of tunable, synthesized Band Reject Filters for solving interference problems in Radar/Electronic Warfare (“RADAR/EW”) applications. Self-protection systems onboard high-performance military aircraft often require RADAR filters to block electromagnetic interference generated by other onboard electronic systems, primarily from the aircraft’s main RADAR system. These high-speed, tunable notch filters can quickly block interference from both continuous wave and wide bandwidth emissions. Using proprietary driver and phase lock technology, these filters offer tuning speeds that are up to ten times faster than traditional filter designs. We design these filters specifically for each application. Microsource’s two largest customers are prime contractors for which it develops and manufactures RADAR filters used in fighter jet aircraft.

The Giga-tronics Division designs, manufactures and markets a family of functional test products for the RADAR/EW segment of the defense electronics market. Our RADAR/EW test products are used to evaluate and improve the performance of RADAR/EW systems.

The table below presents information for the two reportable segments (In thousands):

	Three Month Period Ended June 25, 2022									Three Month Period Ended June 26, 2021
Description	Giga-tronics Division			Microsource			Total			Giga-tronics Division			Microsource		Total

Assets (at period end)	$	6,277		$	1,955		$	8,232		$	5,640		$	2,571	$	8,211

During the first quarter of fiscal 2023, one customer accounted for 41% of the Company’s consolidated revenues and was included in the Giga-tronics Division segment. A second customer accounted for 37% of the Company’s consolidated revenues and was included in the Microsource segment. A third customer accounted for 15% of the Company’s consolidated revenues and was included in the Giga-tronics Division segment.

During the first quarter of fiscal 2022, one customer accounted for 85% of the Company’s consolidated revenues and was included in the Microsource segment. A second customer accounted for 14% of the Company’s consolidated revenues and was included in the Microsource segment.

Note 14. Income Taxes

The Company accounts for income taxes using the asset and liability method as codified in ASC 740, Income Taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards.

The Company recorded no income tax expense for the three months ended June 25, 2022 and June 26, 2021. The effective tax rate for the three months ended June 25, 2022 and June 26, 2021 was 0% each year, primarily due to a valuation allowance recorded against the net deferred tax asset balance.

As of June 25, 2022, the Company had recorded $52,000 for unrecognized tax benefits related to uncertain tax positions. The unrecognized tax benefit is netted against the non-current deferred tax asset on the unaudited condensed consolidated Balance Sheet. The Company does expect the liability for unrecognized tax benefits to change materially during the next 12 months.

Note 15. Warranty Obligations

The Company records a liability for estimated warranty obligations in cost of revenue at the date products are sold. Adjustments are made as new information becomes available. The Company provides no other guarantees.

Note 16. Preferred Stock and Warrants

Series E Senior Convertible Voting Perpetual Preferred Stock

On March 26, 2018, the Company issued and sold 42,800 shares of a newly designated series of 6.0% Series E Senior Convertible Voting Perpetual Preferred Stock (“Series E Shares”) to approximately 15 investors in a private placement for gross proceeds of approximately $1.1 million. Net proceeds to the Company after fees and expenses were approximately $1.0 million. During the 2019 fiscal year, the Company issued and sold an additional 56,200 Series E Shares resulting in additional gross proceeds of $1,405,000 or approximately $1.2 million after fees and expenses of approximately $212,000.

Holders of Series E Shares are entitled to receive, when, as and if declared by the Company’s Board of Directors, cumulative preferential dividends, payable semiannually in cash at a rate per annum equal to 6.0% of the initial purchase price of $25.00 per share or in-kind (at the Company’s election) through the issuance of shares of the Company’s common stock, based on the 10 day volume weighted average price of the common stock. The deemed dividend is reflected on the face of the income statement as a decrease in net income (or increase in net loss) to arrive at net income or loss attributable to common shareholders.

On November 7, 2019 the Company issued an aggregate of 896,636 shares of common stock in exchange for 88,600 shares of Series E Preferred Stock and the unpaid dividends accrued thereon. The shares of common stock issued in the exchange were issued in reliance on the exemption from registration set forth in Section 3(a)(9) of the Securities Act of 1933 (the “Securities Act”), though other exemptions may be available.

During the three months ended June 25, 2022, no exchange of Series E Preferred Stock was done by the Company.

The table below presents Preferred Stock information as of June 25, 2022 and March 26, 2022 (In thousands):

Preferred Stock As of June 25, 2022 and March 26, 2022	Designated Shares		Shares Issued and Outstanding		Liquidation Preference

Note 17. COVID-19 (Coronavirus)

On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus (“COVID-19”) and in March 2020 classified the outbreak as a pandemic. In March 2020, the President of the United States and the Governor of California declared a state of emergency, based on the rapid increase in COVID-19 cases including in California. In response to the COVID-19 pandemic, the Company has implemented a number of measures intended to ensure the safety of personnel and the continuity of operations. Following a mandated shut down in March 2020, the Company was designated as an essential business and has largely returned to normal operations though it continues to implement and follow the protective measures described above.

The COVID-19 pandemic has caused significant disruptions to the global, national and local economies. The overall economic and other impacts of the COVID-19 pandemic in the areas in which the Company and its customers and suppliers operates is not known and cannot be predicted at this time. While the disruption is currently expected to be temporary, there is uncertainty about the duration and the total economic impact. If this situation is prolonged, the pandemic could cause additional delays and could have a short- or long-term adverse impact, possibly material, on the Company’s future financial condition, liquidity, and results of operations.

To mitigate these risks, the Company has purchased long-lead inventory ahead of order receipt according to a forecast of anticipated business for its EW business. Microsource generally buys inventory upon receipt of each contract but has experienced delays in delivery

16

of specialty components and certain chips needed for its RADAR filter production. Microsource management is working to secure supply of these materials to minimize gaps in delivery to its customers.

Note 18. Share Exchange Agreement with BitNile and Gresham

On December 27, 2021, Giga-tronics entered into the Share Exchange Agreement with BitNile and Gresham. The Share Exchange Agreement provides that the Company will acquire all of the outstanding shares of capital stock of Gresham in exchange for issuing to BitNile 2,920,085 shares of the Company’s common stock and 514.8 shares of a new series of preferred stock that are convertible into an aggregate of 3,960,043 shares of the Company’s common stock, subject to potential adjustments, and the assumption of Gresham’s outstanding equity awards representing, on an as-assumed basis, 249,875 shares of the Company’s common stock (“Exchange Transaction”). Completion of the Exchange Transaction is subject to the approval of the Company’s shareholders and other customary closing conditions.

Immediately following the completion of the Exchange Transaction, Gresham will be a wholly-owned subsidiary of the Company. Outstanding shares of the Company’s common stock, warrants and options will remain outstanding and unaffected upon completion of the Exchange Transaction. The Company’s common stock will continue to be registered under the Exchange Act immediately following the Exchange Transaction.

The Share Exchange Agreement further provides that BitNile will loan the Company $4.25 million upon the closing of the Exchange Transaction and the Company will use these funds, in part, to repurchase or redeem all of the currently outstanding shares of the Company's Series B, Series C, Series D and Series E preferred stock (“Outstanding Preferred”). The Share Exchange Agreement further provides that following the Exchange Transaction, the Company will pursue an underwritten public offering of $25 million of its common stock. BitNile has agreed to purchase up to $10 million of common stock in the offering, which amount would include the conversion of the $4.25 million to be loaned to the Company upon the closing of the Exchange Transaction.

The Share Exchange Agreement contains certain termination rights for each of the parties, including the right of the Company or BitNile to terminate the Share Exchange Agreement if the Exchange Transaction is not consummated by August 31, 2022.

On April 5, 2022, the Company (1) amended the Share Exchange Agreement, (2) borrowed an additional $500,000 from DPL, and (3) issued a warrant to Gresham.

The Amendment to the Share Exchange Agreement

On April 5, 2022, the Company, BitNile and Gresham amended the Share Exchange Agreement by entering into Amendment No. 1 to the Share Exchange Agreement (“Amendment”). The Amendment (1) extends from June 30, 2022 to August 31, 2022 the earliest date on which either the Company or BitNile may terminate the Share Exchange Agreement for any reason if the share exchange contemplated by the Share Exchange Agreement is not completed (assuming the terminating party’s breach of the Share Exchange Agreement is not the principal cause of the failure to complete the share exchange) (“End Date Termination”), (2) restates an existing provision of the Share Exchange Agreement, which provides that if the Company terminates the Share Exchange Agreement, it must repay the loan from an affiliate of BitNile the following business day, to reflect the full principal amount of such loan, which is $1,300,000 after giving effect to the additional funding described below, and (3) provides for the Company’s issuance of a warrant to Gresham, which is described in more detail below.

The Warrant

On April 5, 2022, as contemplated by the Amendment, the Company issued to Gresham a warrant representing the right to purchase 433,333 shares of its common stock (“Warrant Shares”) at the initial exercise price of $3.00 per share. The Warrant will become exercisable if the closing of the Exchange Transaction contemplated by the Share Exchange Agreement does not occur, unless the failure to close results (1) solely from BitNile’s or Gresham’s breach of the Share Exchange Agreement or (2) BitNile’s election to terminate the Share Exchange Agreement pursuant to the End Date Termination provision (“Trigger Date”). The Warrant may be exercised in whole or part for a period of three years following the Trigger Date or, if earlier, until December 31, 2025. A Warrant holder may not exercise the Warrant with respect to any Warrant Shares that would cause such holder to beneficially own in excess of 4.99% of the Company’s outstanding common stock, though a holder may elect to increase this limit to 9.9% of the Company’s common stock on at least 61 days written notice. The Warrant may be exercised for cash or, if there is no effective registration statement covering the resale of the Warrant Shares, the Warrant may be exercised on a cashless basis beginning six months after the Trigger Date. The number of Warrant Shares issuable upon exercise of the Warrant is subject to adjustment for splits, subdivisions or consolidations of shares and other standard dilutive events, or in the event the Company effects a reorganization, reclassification, merger, consolidation, disposition of assets, or other fundamental transaction. In addition, subject to certain exempt issuances, if at any time while the Warrant is outstanding, the Company sells, issues or grants any shares of Company common stock or other securities entitling the holder to acquire shares of Company common stock at a price per share less than the then exercise price, the exercise price shall be reduced to equal the lesser of either such lesser price or the volume-weighted average price on the next trading date following the first public disclosure of

17

the issuance. The Warrant includes a most favored nation clause providing that if the Company issues or sells any shares of common stock or any securities of the Company which would entitle the holder of such securities to acquire common stock on terms the holder reasonably believes are more favorable than those in the Warrant, at the request of the holder, the Company shall amend the Warrant to include such terms.

ITEM 2 - MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Giga-tronics manufactures specialized electronic equipment for use in military test and airborne operational applications. Our operations consist of two business segments, those of our wholly owned subsidiary, Microsource Inc., and those of our Giga-tronics Division. Microsource designs and manufactures custom microwave products for military airborne applications while the Giga-tronics Division designs and manufactures real time solutions for RADAR/EW test applications.

Our Microsource subsidiary generates revenue through sole-source production contracts for custom engineered components funded by the United States ("U.S.") Federal Government. Microsource revenue for the first three months of fiscal year 2022 was $2.0 million from the delivery of RADAR filters for the F-15D, F-16 and F/A-18E aircrafts. These filters solve an interference problem that occurs between the aircraft’s RADAR system and the onboard electronic warfare suite when these older aircrafts receive upgraded RADAR systems. The engineering of each filter variant was funded by the U.S. Government indirectly through prime contractors, including filters for foreign military sales.

Orders for Microsource components are typically between $1.0 million to $3.0 million each and involve production contracts where the period of performance spans multiple years. We believe opportunities exist for expanding the use of our Microsource RADAR filters by offering design variants, such as for use in other aircraft or in situations where the electronic warfare suite is externally mounted on a pylon rather than onboard the aircraft. Microsource will also pursue development contracts for adapting the Company’s up/down converter technology for the benefit of customers who will appreciate the faster operation of our RADAR filters, representing a potential source of new revenue as customers upgrade their installed base.

Our Giga-tronics Division participates in the electronic warfare test segment with modular microwave up and down converters, our real-time TEmS and integrated playback and record solutions. The Giga-tronics solutions are architected like a RADAR system but built like a test system. We believe this approach differentiates our TEmS system from the competing solutions and provides a better correlation between laboratory tests and actual field results. The platform was specifically designed to address the need for multiple test channels and delivers a product that is smaller, more flexible, much easier to use and much lower in cost than those previously available.

We have sold our TEmS solution for use in air-crew training and air-to-ground missile testing applications. Our early sales for air-crew training and air-to-ground missile testing solutions leads us to believe that we can grow our market share faster in the field range testing segment compared to laboratory settings. Management expects that air-crew training and field testing on ranges throughout the country represent an opportunity for the growth of the Company’s EW test business revenue in fiscal 2023.

COVID-19 Impact

Following the initial impact of the COVID-19 pandemic in early 2020, Giga-tronics was identified early on as an essential business by the U.S. Department of Homeland Security due to the importance of our Microsource RADAR filters to the U.S. Department of Defense. The Company restored operations as quickly as feasible while taking the necessary steps to protect our employees from potential harm. During fiscal 2021, Giga-tronics applied for and received a loan of $786,200 from the Small Business Administration (“SBA”) associated with the U.S. Government’s Payroll Protection Program. The loan, including all accrued interest, was subsequently forgiven in November 2020 and was recorded as a gain on extinguishment of debt during our first quarter of fiscal 2021.

The COVID-19 pandemic had a significant impact on our ability to directly interact in person with customers throughout most of fiscal 2021 and fiscal 2022. Consequently, the progress in demonstrating solutions to customers and increasing awareness of Giga-tronics within the user community was delayed. Furthermore, we were unable to discuss customer needs and how our solutions could solve their problems as the military bases blocked outside personnel from visiting and mandated many of their personnel to work from home. In addition, travel restrictions made it difficult for our sales team to visit locations throughout the country due to mandatory quarantine periods. Requirements for visitation vary among the services and as a minimum require negative COVID test, proof of vaccination and advanced notices and approvals of planned visits.

The pandemic also impacted our supply chain during most of fiscal 2021 and fiscal 2022. Many of our suppliers have indicated similar challenges in keeping their own operations running and management believes we may continue to experience delays in fulfilling orders due limited availability of parts and services throughout fiscal 2023.

While we expect the impact of COVID-19 to be temporary, the disruptions caused by the pandemic negatively impacted our revenue and results from operations beginning in March 2020 and throughout most of fiscal years 2021 and 2022. Looking ahead, we see that our sales team is better able to interact with and demonstrate our solutions to customers, and as a result we anticipate a positive impact on orders for our Giga-tronics EW test solutions in fiscal year 2023.

Critical Accounting Policies

Please refer to the section of the Company’s Annual Report on Form 10-K for the year ended March 26, 2022 entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies” for a discussion of our critical accounting policies. During the three months ended June 25, 2022, there were no material changes to these policies other than as disclosed in Note 1 Organization and Significant Accounting Policies to our unaudited condensed consolidated financial statements included with this Quarterly Report on Form 10-Q.

In preparing the unaudited condensed consolidated financial statements, management is required to make estimates based on the information available that affect the reported amounts of assets and liabilities as of the balance sheet dates and revenues and expenses for the reporting periods. While we believe that these accounting policies and estimates are based on sound measurement criteria, actual future events can and often do result in outcomes that can be materially different from these estimates and forecasts.

Results of Operations

New orders by reporting segment are as follows at the end of the respective periods (In thousands):

	Three Months Ended
Segment	June 25, 2022		June 26, 2021		$ Change			% Change
Giga-tronics Division	$	864	$	387	$	477			123	%
Microsource		755		1,124		(369	)		(33	)%
Total	$	1,619	$	1,511	$	108			7	%

New orders received in the first quarter of fiscal 2023 increased by $108,000 to $1.6 million. The Giga-tronics Division booked a TEmS order in the first quarter of fiscal 2023, as compared to several synthesizer orders booked in the first quarter of fiscal 2022. The Microsource business unit booked a RADAR filter order from a prime contractor in the first quarter of fiscal 2023 as compared to a spares order and a non-recurring engineering order from two prime contractors in the first quarter of fiscal 2022. The timing of receipt of RADAR filter contracts and EW Test orders can vary significantly from period to period.

The following table shows order backlog and related information at the end of the respective periods (In thousands):

	As of
Segment	June 25, 2022		June 26, 2021		$ Change			% Change
Giga-tronics Division	$	8	$	406	$	(398	)		(98	)%
Microsource		1,040		4,171		(3,131	)		(75	)%
Total	$	1,048	$	4,577	$	(3,529	)		(77	)%

Backlog at the end of the first three months of fiscal 2023 decreased 77% compared to the same period prior year. Giga-tronics Division backlog on June 25, 2022 was $8,000, a large percentage decrease from the comparable prior year period. Microsource experienced a 75% decrease in backlog in the first three months of fiscal 2023 due primarily to lower bookings during that period.

The allocation of net revenue was as follows for the periods shown (In thousands):

	Three Months Ended
Segment	June 25, 2022		June 26, 2021		$ Change			% Change
Giga-tronics Division	$	1,167	$	51	$	1,116			2,188	%
Microsource		763		1,999		(1,236	)		(62	)%
Total	$	1,930	$	2,050	$	(120	)		(6	)%

The Giga-tronics Division net revenue for the first fiscal quarter ended June 25, 2022 was $1.2 million, a 2,188% increase from the comparable prior year quarter. The Giga-tronics Division shipped a TEmS order and multiple synthesizers in the first quarter of fiscal 2023, as compared to some service revenue in the first quarter of fiscal 2022. Net revenue for the Microsource segment during the quarter ended June 25, 2022 decreased 62% over the comparable prior year period primarily due lower orders. The timing of receipt of expected large RADAR filter orders varies from period to period.

Cost of revenue and gross profit was as follows for the periods shown (In thousands):

	Three Months Ended					Three Months Ended
Segment	June 25, 2022		% of Segment Revenue			June 26, 2021		% of Segment Revenue
Giga-tronics Division	$	903		77	%	$	54		106	%
Microsource		613		80	%		1,196		60	%
Total cost of revenue	$	1,516		79	%	$	1,250		61	%
Gross profit	$	414		21	%	$	800		39	%

Gross profit decreased by $386,000 in the first quarter of fiscal 2023 as compared to the first quarter of fiscal 2022 primarily due to the decrease in revenue at the Microsource segment as described above.

Operating expenses were as follows for the periods shown (In thousands):

	Three Months Ended
Category	June 25, 2022		June 26, 2021		$ Change			% Change
Engineering	$	298	$	402	$	(104	)		(26	)%

Transaction expenses		164		—		164			—	%
Total	$	1,624	$	1,500	$	124			8	%

Total operating expenses increased 8% or $124,000 in the first quarter of fiscal 2023 versus the first quarter of fiscal 2022. Engineering expenses decreased by $104,000 primarily due to reduced engineering personnel costs and a greater portion of non-recurring engineering expenses for contract services which were allocated to cost of revenue. Selling, general and administrative expenses increased by 6% primarily due to recruiting expenses. In addition the Company incurred transaction expenses of $164,000 associated with the aforementioned Share Exchange Agreement (See Note 18– Share Exchange Agreement with BitNile and Gresham).

Interest expense, net and other were as follows for the periods shown (In thousands):

	Three Months Ended
Category	June 25, 2022		June 26, 2021		$ Change			% Change
Interest expense, net	$	33	$	3	$	30			1000	%
Deemed dividend on Series E preferred stock	$	2	$	3	$	(1	)		(33	)%
Cumulative dividends on converted Series E    preferred stock	$	—	$	43	$	(43	)		(100	)%

Finance costs from prefunded warrants issuance	$	—	$	157	$	(157	)		(100	)%
Gain on remeasurement of prefunded warrants liability	$	—	$	46	$	(46	)		(100	)%

Net interest expense in the first quarter of fiscal 2023 was $33,000, an increase of $30,000 from the first quarter of fiscal 2022. Interest expense increased primarily due to the $1.3 million loan from DPL (See Note 6– Term Loans).

During the first quarter of fiscal 2023, the Company amortized $13,000 of finance cost related to the warrant issued in connection with the term loan. In addition, the re-measurement of the warrant liability resulted in a gain of $10,000.

During the first quarter of fiscal 2022 the conversion of 35,000 Series E preferred stock to common shares resulted in a $43,000 cumulative dividend non-cash charge. In addition, the issuance of the prefunded warrants incurred financing costs of $157,000 and the re-measurement of the prefunded warrants liability resulted in a gain of $46,000 (See Note 16 – Preferred Stock and Warrants).

Net Loss

Net loss attributable to common shareholders for the first quarter of fiscal 2023 was $1.2 million, compared to a net loss of $860,000 recorded in the first quarter of fiscal 2022. The $383,000 increase in losses during the first quarter of fiscal 2023 was primarily due to

21

lower gross margins along with the transaction related costs of $164,000 in the first quarter of fiscal 2023 versus the comparable prior year period.

Financial Condition and Liquidity

	As of
Category (In thousands)	June 25, 2022		March 26, 2022
Cash	$	400	$	25
Total current assets	$	7,043	$	6,850
Total current liabilities	$	5,601	$	4,114
Working Capital	$	1,442	$	2,736
Current ratio	1.26		$	1.67

Our primary sources of liquidity are customer sales and our Restated Financing Agreement with Western Alliance Bank, both of which are dependent on our receipt and shipment of customer orders, and capital raised from investors and lenders. Therefore, if we are unable to maintain sufficient levels of liquidity solely from sales to customers and borrowings under the Restated Financing Agreement, we may be required to seek funding from other sources. To address our liquidity needs in the near term, we entered into a loan agreement with DPL, an affiliate of BitNile, the parent company of Gresham, and borrowed $500,000 on November 12, 2021 (See Note 6 – Term Loan). We borrowed an additional $300,000 on January 7, 2022 and an additional $500,000 on April 5, 2022, and the outstanding principal amount of the DPL loan as of June 25, 2022 is $1,300,000. The DPL loan matures in November 2022 but if we exercise our right to terminate the Share Exchange Agreement, we must repay the DPL loan immediately. Our Share Exchange Agreement provides that following our acquisition of Gresham, we will pursue an underwritten public offering of $25 million of our common stock in which BitNile will purchase $10 million of our common stock, which amount shall include the conversion of the $4.25 million loan that BitNile will make to us upon the closing of our acquisition of Gresham. There can be no assurance that we will successfully complete the public offering or that additional financing will be available to us in the future. Our ability to obtain additional financing is subject to several factors, including market and economic conditions, our performance and investor and lender sentiment with respect to us and our industry. If we are unable to raise additional financing in the near term as needed, our operations and production plans may be scaled back or curtailed and our operations and growth would be impeded.

Our near-term fixed commitments for cash expenditures are primarily for payments for employee salaries, operating leases and inventory purchase commitments.

Cash Flows

The following summary of our cash flows for the periods indicated has been derived from our unaudited condensed consolidated financial statements included elsewhere in this filing (In thousands):

	Three Months Ended
Category	June 25, 2022			June 26, 2021
Net cash used in operating activities	$	(716	)	$	(699	)
Net cash used in investing activities		(41	)		—
Net cash provided by financing activities		1,132			993
Net increase in cash		375			294
Cash at the beginning of the fiscal year		25			736
Cash at the end of the period	$	400		$	1,030

Cash Flows from Operating Activities

During the first three months of fiscal 2023, cash used in the operating activities was $716,000, as compared to $699,000 in the first three months of fiscal 2022. The primary use of cash in the first quarter of fiscal 2023 was to finance net losses.

We expect that cash flows from operating activities will fluctuate in future periods due to a number of factors including our level of revenue, which fluctuates significantly from one period to another due to the timing of receipt of contracts, operating results, amounts of non-cash charges, and the timing of our inventory purchases, billings, collections and disbursements.

22

Cash Flows from Financing Activities

Cash provided by financing activities for the three month period ended June 25, 2022 was $1.1 million which was primarily due to an increase in our accounts receivable factoring credit line. In addition, we borrowed an additional $500,000 from DPL.

Non-GAAP Financial Measures

A Non-GAAP financial measure is generally defined by the SEC as a numerical measure of a company’s historical or future performance, financial position or cash flows that includes or excludes amounts from the most directly comparable measure under GAAP. Non-GAAP financial measures should be viewed in addition to, and not as an alternative to, our reported results prepared in accordance with GAAP. Users of this financial information should consider the types of events and transactions that are excluded from these measures.

We measure our operating performance in part based on earnings before interest, taxes, depreciation and amortization (“EBITDA”). We also measure our operating performance based on “Adjusted EBITDA,” which we define as EBITDA adjusted for net other income or expense items, share based compensation and certain one-time income or expense items. EBITDA and Adjusted EBITDA are non-GAAP financial measures that are commonly used, but neither is a recognized accounting term under GAAP. We use EBITDA and Adjusted EBITDA to monitor and facilitate internal evaluation of the performance of our business operations, to facilitate external comparison of our business results to those of others in our industry, and to plan and evaluate our operating budgets. We believe that our measures of EBITDA and Adjusted EBITDA provide useful information to the investing public regarding our operating performance and our ability to service debt and fund capital expenditures and may help investors understand and compare our results to other companies that have different financing, capital and tax structures. Neither EBITDA nor Adjusted EBITDA should be considered in isolation or as a substitute for, but as a supplement to, income or loss from operations, net income or loss, cash flows from operating activities, or other income or cash flow data prepared in accordance with GAAP.

In the following reconciliation, we provide amounts as reflected in our accompanying unaudited condensed consolidated financial statements unless otherwise noted.

The reconciliation of our Net loss to EBITDA and Adjusted EBITDA is as follows (In thousands):

	Three Months Ended
	June 25, 2022			June 26, 2021
Net loss	$	(1,246	)	$	(814	)

Adjustments:

Accounting Policies [Abstract]

Organization and Significant Accounting Policies

Note 1. Organization and Significant Accounting Policies

The unaudited condensed consolidated financial statements included herein have been prepared by Giga-tronics Incorporated (“Giga-tronics,” “Company,” or “we”), pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the fiscal year. In the opinion of management, the information contained herein reflects all adjustments (consisting of normal recurring entries) necessary to make the consolidated results of operations for the interim periods a fair statement of such operations. Please refer to the Company’s Annual Report on Form 10-K for the year ended March 26, 2022 for a discussion of our significant accounting policies. During the three months ended June 26, 2022, there were no material changes to these policies other than as disclosed below. For further information, refer to the consolidated financial statements and footnotes thereto, included in the Annual Report on Form 10-K, filed with the SEC for the year ended March 26, 2022.

Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of Giga-tronics and its wholly owned subsidiary, Microsource, Inc. (“Microsource”). All significant intercompany balances and transactions have been eliminated in consolidation.

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

Going Concern and Management's Plan [Abstract]

Going Concern and Management's Plan

Note 2. Going Concern and Management’s Plan

The Company incurred net losses of $1.2 million in the first quarter ended June 25, 2022 and $2.7 million in the fiscal year ended March 26, 2022. These losses have contributed to an accumulated deficit of $35.2 million as of June 25, 2022.

On December 27, 2021, Giga-tronics entered into a Share Exchange Agreement with BitNile Holdings, Inc. ("BitNile") and Gresham Worldwide, Inc. (“Gresham”), which is a wholly-owned subsidiary of BitNile (the “Share Exchange Agreement”). Under the Share Exchange Agreement, the Company is restricted from raising funds either via debt or equity and has therefore received a loan of $1.3 million from Digital Power Lending, LLC, (“DPL”) which is an affiliate of BitNile. The Company expects to complete the merger with Gresham in September 2022 and resolve the going concern matter (See Note 18 - Share Exchange Agreement with BitNile and Gresham).

Management has also put in place a plan as a stand-alone company and believes that the Company can repay the loan to BitNile in November 2022 without raising additional funding because of the large inventory on hand for the Threat Emulation System ("TEmS") solution, which will result in cash with sales of the TEmS solution. Management will continue to review all aspects of its business including, but not limited to, the contribution of its individual business segments, in an effort to improve cash flow and reduce costs and expenses, while continuing to invest, to the extent possible, in new product development for future revenue streams.

The Company's historical operating results and forecasting uncertainties indicate that substantial doubt exists related to its ability to continue as a going concern. Management believes that through the actions to date and possible future actions described above, the Company should have the necessary liquidity to continue operations for at least twelve months from the issuance of the financial statements. However, management cannot predict, with certainty, the outcome of its actions to maintain or generate additional liquidity, including the availability of additional financing, or whether such actions would generate the expected liquidity as currently planned. Forecasting uncertainties also exist with respect to the Electronic Warfare ("EW") test system product line due to the potential longer than anticipated sales cycles.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern and do not include any adjustments that might result if the Company were unable to do so.

On April 5, 2022, the Company (1) borrowed an additional $500,000 from DPL, (2) amended its Share Exchange Agreement and issued a warrant to Gresham. The Share Exchange Agreement and the warrant issued to Gresham are described in Note 18 – Share Exchange Agreement with BitNile and Gresham.

The loan is evidenced by a secured promissory note dated April 5, 2022 that provides, among other things that the principal amount of the loan will bear interest at the rate of 10.0% per annum. Unless prepaid by the Company, all principal and accrued interest under the loan is payable on November 12, 2022 or, if earlier, upon the Company’s completion of an underwritten public offering or the

termination of the Share Exchange Agreement. The Company’s obligations under the loan are secured by a pledge of all of the Company’s assets. The loan and the lender’s security interest are subordinate to the Company’s existing bank lending arrangement.

As of June 25, 2022, and March 26, 2022, the Company’s total outstanding loan balance was $1,300,000 and $800,000, respectively, and are included in Loans payable, net of discounts and issuance costs on the unaudited condensed consolidated Balance Sheets.

On April 5, 2022, the Company borrowed an additional $500,000 from DPL and the Company and DPL entered into an Amended and Restated Secured Promissory Note and an amendment to the Security and Pledge Agreement originally dated as of November 12, 2021 to reflect that the Company has borrowed an aggregate of $1,300,000 from DPL. The Company intends to use the additional loan proceeds for general corporate purposes. The other material terms of the Loan remain unchanged.

Leases

Note 8. Leases

Operating leases

The Company has a non-cancelable operating lease for office, research and development, engineering, laboratory, storage and warehouse uses in Dublin, California for 77 months from April 1, 2017 through August 31, 2023. The Company agreed to pay an aggregate base rent of $2,384,913 for the period of 77 months, with an annual increase of $0.05 per rentable square foot for each subsequent year. The lease provided for rent abatement of $173,079 during the initial five months of the lease term, subject to the Company performing the terms and conditions required under the lease, and certain tenant improvements completed at the landlord’s expense of $358,095.

In December 2018, the Company entered into a lease agreement for an additional 1,200 square foot facility for certain engineering personnel located in Nashua, New Hampshire, which began on February 1, 2019. Effective March 1, 2020, we amended and replaced in its entirety the original Nashua lease agreement to increase the facility size to 2,400 square feet and extend its expiration to February 28, 2023.The monthly payment for fiscal year 2022 and fiscal year 2023 under the amended agreement is $2,500.

Per the terms of the Company’s lease agreements, the Company does not have any residual value guarantees. In calculating the present value of the lease payments, the Company has elected to utilize its incremental borrowing rate. The Company has elected for facility operating leases to not separate each lease component from its associated non-lease components. The building lease includes variable payments (i.e., common area maintenance) which are charged and paid separately from rent based on actual costs incurred and therefore are not included in the right-of-use asset and liability but reflected in operating expense in the period incurred.

Fair Value Measurement

Fair Value Disclosures [Abstract]

Fair Value Measurement

Note 9. Fair Value Measurement

Accounting Standards Codification ("ASC") 820 “Fair Value Measurements” ("ASC 820") defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. ASC 820 defines fair value 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. ASC 820 establishes a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

The three levels of the fair value hierarchy under ASC 820 are described below:

•Level 1 —Valuations are based on quoted prices in active markets for identical assets or liabilities and readily accessible by us at the reporting date. Examples of assets and liabilities utilizing Level 1 inputs are certain money market funds, U.S. Treasuries and trading securities with quoted prices in active markets.

•Level 2 —Valuations based on inputs other than the quoted prices in active markets that are observable either directly or indirectly in active markets. Examples of assets and liabilities utilizing Level 2 inputs are U.S. government agency bonds, corporate bonds, commercial paper, certificates of deposit and over-the-counter derivatives.

•Level 3 —Valuations based on unobservable inputs in which there is little or no market data, which require us to develop our own assumptions.

In determining the fair value of warrants, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value.

Upon issuance on April 5, 2022 and at June 25, 2022 the warrant issued in connection with loan from DPL was measured at fair value (See Note 18 - Share Exchange Agreement with BitNile and Gresham).

The Company’s fair value hierarchies for its financial assets and liabilities which require fair value measurement on a recurring basis are as follows:

(In thousands)	Level 1		Level 2		Level 3		Total
Balance at March 26, 2022
Liabilities

Balance at June 25, 2022
Liabilities
Warrant liability for warrant issued in connection with loan from DPL	$	—	$	—	$	24	$	24

During the three months ended June 25, 2022 and the year ended March 26, 2022, there were no transfers between Level 1, Level 2, or Level 3 assets or liabilities reported at fair value and the valuation techniques used did not change compared to the Company’s established practice.

The fair value of the warrant issued in connection with loan from DPL has been determined using Black-Scholes-Merton model. The Company’s common stock fair value is a significant Level 3 input affecting the valuation of the warrant.

(In thousands)	Warrant liability
Balance at March 26, 2022	$	—
Initial fair value of warrants issued in connection with loan from DPL in April 2022		34
Gain on remeasurement of warrant issued in connection with loan from DPL		(10	)
Balance at June 25, 2022	$	24

Upon issuance on April 27, 2021, the prefunded warrants liability was measured at fair value. On July 28, 2021, the Company and the holder amended the terms of the Prefunded Warrants to restrict the holder’s option to require cash payment at the Black-Scholes-Merton model value of the remaining unexercised portion of the holder’s Prefunded Warrants to only Fundamental Transactions that are within the Company’s control. Because of this modification of the put-option provision, the Prefunded Warrants are no longer required to be classified as a liability under either ASC 480, "Distinguishing Liabilities from Equity", or ASC 815, "Derivatives and Hedging", guidance and do not include any embedded features that require bifurcation. Therefore, the Prefunded Warrants liability were remeasured on the modification date and reclassified to equity (See Note 10 – Sale of Common Stock and Prefunded Warrants). As of June 25, 2022 and March 26, 2022, the prefunded warrants liability was $0.

There were no assets measured at fair value on a recurring basis and there were no assets measured at fair value on a non-recurring basis as of June 25, 2022 and March 26, 2022. There were no liabilities measured at fair value on a recurring or non-recurring basis at March 26, 2022.

Note 10. Sale of Common Stock and Prefunded Warrants

On April 27, 2021, the Company entered into a Securities Purchase Agreement (“Purchase Agreement”) with certain accredited investors (“Investors”) pursuant to which it issued and sold prefunded warrants to purchase an aggregate of 461,538 shares of the Company’s common stock (“Prefunded Warrants”) for gross proceeds of $1,500,000 or $3.25 per Prefunded Warrant in a private placement on the same day. Net proceeds to the Company after fees and expenses of the private placement were approximately $1,343,000. The Purchase Agreement contains customary representations and warranties of the Company and certain indemnification obligations and ongoing covenants of the Company.

The Prefunded Warrants are immediately exercisable and may be exercised for a de-minimis exercise price of $0.01 per share subject to the limitation that a holder of a Prefunded Warrant will not have the right to exercise any portion of the Prefunded Warrant if the holder together with its affiliates and attribution parties (as such terms are defined in the Prefunded Warrants) would beneficially own in excess of 9.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Prefunded Warrants. The Prefunded Warrants do not expire. The Prefunded Warrants also contained a put option, exercisable under certain conditions. Because of this put-option provision, the Prefunded Warrants were initially classified as a liability at fair value of $1,703,000 on the issuance date and marked to market at each reporting date. Further, because the fair value of the prefunded warrant liability on the issuance date was greater than the proceeds of the Prefunded Private Placement and the warrants were issued to existing common stockholders, the difference was recorded to accumulated deficit as a $203,000 deemed dividend. There were finance costs of $157,000 associated with the issuance of the Prefunded Warrants. There was a gain on measurement of $46,000 on the prefunded warrant liability in the first quarter of fiscal 2022 and $46,000 in the second quarter of fiscal 2022.These amounts are recorded in “Other income (expense), net” in the unaudited condensed consolidated Statements of Operations.

Pursuant to the terms of the Purchase Agreement, and as a condition to closing the private placement, the Company and each Investor simultaneously entered into a registration rights agreement (“Registration Rights Agreement”) requiring the Company to file a registration statement with the SEC within 45 days of the closing of the private placement to register for resale the shares of the Company’s common stock underlying the Prefunded Warrants. The Registration Rights Agreement contains customary terms and conditions, certain liquidated damages provisions for failing to comply with the timing obligations for the filing and effectiveness of the registration statement, and certain customary indemnification obligations.

On April 27, 2021, in connection with the private placement, the Company issued warrants to purchase 23,076 shares of the Company’s common stock to the placement agent for such offering (“Placement Agent Warrants”). The Placement Agent Warrants have an exercise price per share equal to $3.575, subject to adjustment in certain circumstances, and will expire on April 27, 2026. The Placement Agent Warrants do not have the same put option provision as the original Prefunded Warrants and, therefore, are classified as equity.

On June 6, 2021, the Company entered into a Securities Purchase Agreement with a private investor for the sale of a total of 46,154 common shares at the price of $3.25 per share, for aggregate gross proceeds of $150,000. The sale was completed, and the shares of common stock were issued on June 6, 2021. Net proceeds to the Company after fees and expenses of the transaction were approximately $145,000 (See Note 16 - Preferred Stock and Warrants).

On July 28, 2021, the Company and the holder amended the terms of the Prefunded Warrants to restrict the holder’s option to require cash payment at the Black-Scholes-Merton value of the remaining unexercised portion of the holder’s Prefunded Warrants to only Fundamental Transactions that are within the Company’s control. Because of this modification of the put-option provision, the Prefunded Warrants are no longer required to be classified as a liability under either ASC 480, "Distinguishing Liabilities from Equity", or ASC 815, "Derivatives and Hedging", guidance and do not include any embedded features that require bifurcation. Therefore, the Prefunded Warrants liability were remeasured on the modification date of July 28, 2021 and reclassified to equity as of that date.

Earnings Per Share [Abstract]

Net Loss Per Share

Note 11. Net Loss Per Share

Basic loss per share is calculated by dividing net loss by the weighted average common shares outstanding during the period. Diluted earnings per share (“EPS”) reflects the net incremental shares that would be issued if unvested restricted shares became vested and dilutive outstanding stock options and warrants were exercised, using the treasury stock method. In addition, certain options are considered anti-dilutive because assumed proceeds from exercise price, related tax benefits and average future compensation was greater than the weighted average number of options outstanding multiplied by the average market price during the period.

Shares excluded from the diluted EPS calculation for the three month periods ended June 25, 2022 and June 26, 2021 are as follows (In thousands):

Anti-dilutive securities	June 25, 2022		June 26, 2021
Common shares issuable upon exercise of stock options		335		378
Restricted stock awards		30		15
Common shares issuable upon conversion of convertible preferred stock		157		157
Common shares issuable upon exercise of warrants		530		530

There were no dilutive securities in the three months ended June 25, 2022 and June 26, 2021 because the stock options, restricted stock awards, convertible preferred stocks and warrants were all anti-dilutive.

Stock-based Compensation and Employee Benefit Plans

Notes To Financial Statements [Abstract]

Stock-based Compensation and Employee Benefit Plans

Note 12. Stock-based Compensation and Employee Benefit Plans

The Company maintains a 2018 Equity Incentive Plan which provides for the issuance of up to 416,667 shares of common stock upon the exercise of options, stock awards and grants. With the adoption of the 2018 Equity Incentive Plan, no further awards will be issued under the Company’s 2005 Equity Incentive Plan, though all awards under the 2005 Equity Incentive Plan that are outstanding continue to be governed by the terms, conditions and procedures set forth in the plan and any applicable award agreement.

During the first quarter of fiscal year 2023, the Company did not grant any stock options. The vested portion of all option grants may be exercised only while the grantee is employed by the Company (or while providing services under a service arrangement in the case of non-employees) or within a certain period after termination of employment or service arrangement in the case of non-employees. Options granted to employees shall not have terms in excess of 10 years from the grant date. Holders of options may be granted stock appreciation rights (“SARs”), which entitle them to surrender outstanding awards for a cash distribution under certain changes in ownership of the Company, as defined in the stock option plan. As of June 25, 2022, and March 26, 2022, no SARs have been granted under any option plan.

As of June 25, 2022, there were 91,114 shares of common stock available for issuance of additional awards under the 2018 Equity Incentive Plan. The Company records compensation cost associated with stock-based compensation equivalent to the estimated fair value of the awards over the requisite service period.

Stock Options

In calculating compensation related to stock option grants, the fair value of each stock option was estimated on the date of grant using the Black-Scholes-Merton model and the following weighted average assumptions:

Description	Three Months Ended
	June 25, 2022			June 26, 2021
Dividend yield		—			—
Expected volatility		—	%		107.00	%
Risk-free interest rate		—	%		0.82	%
Expected term (years)		—			5.50

The computation of expected volatility used in the Black-Scholes-Merton model is based on the historical volatility of the Company’s share price. The expected term is estimated based on a review of historical employee exercise behavior with respect to option grants. The risk-free interest rate is based on the U.S. Treasury rates with maturity similar to the expected term of the option on the date of grant. No options were granted during for three month period ended June 25, 2022.

A summary of the changes in stock options outstanding for the three months period ended June 25, 2022 is as follows:

Description	Shares			Weighted Average Price per share		Weighted Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value
Outstanding at March 26, 2022		353,037		$	4.75		7.26	$	—
Forfeited / Expired		(17,836	)		5.22		—		—
Outstanding at June 25, 2022		335,201		$	4.73		7.01	$	—
Exercisable at June 25, 2022		285,028		$	4.85		6.79	$	—
Expected to vest in the future		50,173		$	4.03		8.23	$	—

As of June 25, 2022, there was $341,000 of total unrecognized compensation cost related to non-vested options. The cost is expected to be recognized over a weighted average period of 2.19 years and will be adjusted as forfeitures occur. There were no options exercised in the three-month periods ended June 25, 2022 and June 26, 2021. Share based compensation cost related to stock options recognized in operating results for the three months ended June 25, 2022 and June 26, 2021 totaled $31,000 and $129,000, respectively.

Restricted Stock

The Company granted 10,000 Restricted Stock Awards (“RSAs”) during the first quarter of fiscal 2023 and 0 RSAs during the first quarter of fiscal 2022. RSAs are considered fixed awards as the number of shares and fair value at the grant date is amortized over the requisite service period and will be adjusted as forfeitures occur.

As of June 25, 2022, there was $41,000 of total unrecognized compensation cost related to non-vested RSAs. That cost is expected to be recognized over a weighted average period of 1.08 years and will be adjusted for subsequent changes in estimated forfeitures. Compensation cost recognized for RSAs for the three months ended June 25, 2022 and June 26, 2021 totaled $21,000 and $26,000, respectively.

A summary of the changes in non-vested RSAs outstanding for the three month period ended June 25, 2022 is as follows:

Restricted Stock Awards	Shares		Weighted Average Grant Date Fair Value
Non-vested at March 26, 2022		20,020	$	3.65

Significant Customer and Industry Segment Information

Note 13. Significant Customer and Industry Segment Information

The Company has two reportable segments: Microsource and the Giga-tronics Division. Microsource’s primary business is the design of custom Microwave Integrated Components (“MIC”) as well as the production of MIC components using chip and wire assembly methods. Microsource offers a line of tunable, synthesized Band Reject Filters for solving interference problems in Radar/Electronic Warfare (“RADAR/EW”) applications. Self-protection systems onboard high-performance military aircraft often require RADAR filters to block electromagnetic interference generated by other onboard electronic systems, primarily from the aircraft’s main RADAR system. These high-speed, tunable notch filters can quickly block interference from both continuous wave and wide bandwidth emissions. Using proprietary driver and phase lock technology, these filters offer tuning speeds that are up to ten times faster than traditional filter designs. We design these filters specifically for each application. Microsource’s two largest customers are prime contractors for which it develops and manufactures RADAR filters used in fighter jet aircraft.

The Giga-tronics Division designs, manufactures and markets a family of functional test products for the RADAR/EW segment of the defense electronics market. Our RADAR/EW test products are used to evaluate and improve the performance of RADAR/EW systems.

Income Taxes

Note 14. Income Taxes

The Company accounts for income taxes using the asset and liability method as codified in ASC 740, Income Taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards.

The Company recorded no income tax expense for the three months ended June 25, 2022 and June 26, 2021. The effective tax rate for the three months ended June 25, 2022 and June 26, 2021 was 0% each year, primarily due to a valuation allowance recorded against the net deferred tax asset balance.

As of June 25, 2022, the Company had recorded $52,000 for unrecognized tax benefits related to uncertain tax positions. The unrecognized tax benefit is netted against the non-current deferred tax asset on the unaudited condensed consolidated Balance Sheet. The Company does expect the liability for unrecognized tax benefits to change materially during the next 12 months.

Series E Senior Convertible Voting Perpetual Preferred Stock

On March 26, 2018, the Company issued and sold 42,800 shares of a newly designated series of 6.0% Series E Senior Convertible Voting Perpetual Preferred Stock (“Series E Shares”) to approximately 15 investors in a private placement for gross proceeds of approximately $1.1 million. Net proceeds to the Company after fees and expenses were approximately $1.0 million. During the 2019 fiscal year, the Company issued and sold an additional 56,200 Series E Shares resulting in additional gross proceeds of $1,405,000 or approximately $1.2 million after fees and expenses of approximately $212,000.

Holders of Series E Shares are entitled to receive, when, as and if declared by the Company’s Board of Directors, cumulative preferential dividends, payable semiannually in cash at a rate per annum equal to 6.0% of the initial purchase price of $25.00 per share or in-kind (at the Company’s election) through the issuance of shares of the Company’s common stock, based on the 10 day volume weighted average price of the common stock. The deemed dividend is reflected on the face of the income statement as a decrease in net income (or increase in net loss) to arrive at net income or loss attributable to common shareholders.

On November 7, 2019 the Company issued an aggregate of 896,636 shares of common stock in exchange for 88,600 shares of Series E Preferred Stock and the unpaid dividends accrued thereon. The shares of common stock issued in the exchange were issued in reliance on the exemption from registration set forth in Section 3(a)(9) of the Securities Act of 1933 (the “Securities Act”), though other exemptions may be available.

During the three months ended June 25, 2022, no exchange of Series E Preferred Stock was done by the Company.

COVID-19 (Coronavirus)

Note 17. COVID-19 (Coronavirus)

On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus (“COVID-19”) and in March 2020 classified the outbreak as a pandemic. In March 2020, the President of the United States and the Governor of California declared a state of emergency, based on the rapid increase in COVID-19 cases including in California. In response to the COVID-19 pandemic, the Company has implemented a number of measures intended to ensure the safety of personnel and the continuity of operations. Following a mandated shut down in March 2020, the Company was designated as an essential business and has largely returned to normal operations though it continues to implement and follow the protective measures described above.

The COVID-19 pandemic has caused significant disruptions to the global, national and local economies. The overall economic and other impacts of the COVID-19 pandemic in the areas in which the Company and its customers and suppliers operates is not known and cannot be predicted at this time. While the disruption is currently expected to be temporary, there is uncertainty about the duration and the total economic impact. If this situation is prolonged, the pandemic could cause additional delays and could have a short- or long-term adverse impact, possibly material, on the Company’s future financial condition, liquidity, and results of operations.

To mitigate these risks, the Company has purchased long-lead inventory ahead of order receipt according to a forecast of anticipated business for its EW business. Microsource generally buys inventory upon receipt of each contract but has experienced delays in delivery

of specialty components and certain chips needed for its RADAR filter production. Microsource management is working to secure supply of these materials to minimize gaps in delivery to its customers.

Share Exchange Agreement [Abstract]

Share Exchange Agreement with BitNile and Gresham

Note 18. Share Exchange Agreement with BitNile and Gresham

On December 27, 2021, Giga-tronics entered into the Share Exchange Agreement with BitNile and Gresham. The Share Exchange Agreement provides that the Company will acquire all of the outstanding shares of capital stock of Gresham in exchange for issuing to BitNile 2,920,085 shares of the Company’s common stock and 514.8 shares of a new series of preferred stock that are convertible into an aggregate of 3,960,043 shares of the Company’s common stock, subject to potential adjustments, and the assumption of Gresham’s outstanding equity awards representing, on an as-assumed basis, 249,875 shares of the Company’s common stock (“Exchange Transaction”). Completion of the Exchange Transaction is subject to the approval of the Company’s shareholders and other customary closing conditions.

Immediately following the completion of the Exchange Transaction, Gresham will be a wholly-owned subsidiary of the Company. Outstanding shares of the Company’s common stock, warrants and options will remain outstanding and unaffected upon completion of the Exchange Transaction. The Company’s common stock will continue to be registered under the Exchange Act immediately following the Exchange Transaction.

The Share Exchange Agreement further provides that BitNile will loan the Company $4.25 million upon the closing of the Exchange Transaction and the Company will use these funds, in part, to repurchase or redeem all of the currently outstanding shares of the Company's Series B, Series C, Series D and Series E preferred stock (“Outstanding Preferred”). The Share Exchange Agreement further provides that following the Exchange Transaction, the Company will pursue an underwritten public offering of $25 million of its common stock. BitNile has agreed to purchase up to $10 million of common stock in the offering, which amount would include the conversion of the $4.25 million to be loaned to the Company upon the closing of the Exchange Transaction.

The Share Exchange Agreement contains certain termination rights for each of the parties, including the right of the Company or BitNile to terminate the Share Exchange Agreement if the Exchange Transaction is not consummated by August 31, 2022.

On April 5, 2022, the Company (1) amended the Share Exchange Agreement, (2) borrowed an additional $500,000 from DPL, and (3) issued a warrant to Gresham.

The Amendment to the Share Exchange Agreement

On April 5, 2022, the Company, BitNile and Gresham amended the Share Exchange Agreement by entering into Amendment No. 1 to the Share Exchange Agreement (“Amendment”). The Amendment (1) extends from June 30, 2022 to August 31, 2022 the earliest date on which either the Company or BitNile may terminate the Share Exchange Agreement for any reason if the share exchange contemplated by the Share Exchange Agreement is not completed (assuming the terminating party’s breach of the Share Exchange Agreement is not the principal cause of the failure to complete the share exchange) (“End Date Termination”), (2) restates an existing provision of the Share Exchange Agreement, which provides that if the Company terminates the Share Exchange Agreement, it must repay the loan from an affiliate of BitNile the following business day, to reflect the full principal amount of such loan, which is $1,300,000 after giving effect to the additional funding described below, and (3) provides for the Company’s issuance of a warrant to Gresham, which is described in more detail below.

The Warrant

On April 5, 2022, as contemplated by the Amendment, the Company issued to Gresham a warrant representing the right to purchase 433,333 shares of its common stock (“Warrant Shares”) at the initial exercise price of $3.00 per share. The Warrant will become exercisable if the closing of the Exchange Transaction contemplated by the Share Exchange Agreement does not occur, unless the failure to close results (1) solely from BitNile’s or Gresham’s breach of the Share Exchange Agreement or (2) BitNile’s election to terminate the Share Exchange Agreement pursuant to the End Date Termination provision (“Trigger Date”). The Warrant may be exercised in whole or part for a period of three years following the Trigger Date or, if earlier, until December 31, 2025. A Warrant holder may not exercise the Warrant with respect to any Warrant Shares that would cause such holder to beneficially own in excess of 4.99% of the Company’s outstanding common stock, though a holder may elect to increase this limit to 9.9% of the Company’s common stock on at least 61 days written notice. The Warrant may be exercised for cash or, if there is no effective registration statement covering the resale of the Warrant Shares, the Warrant may be exercised on a cashless basis beginning six months after the Trigger Date. The number of Warrant Shares issuable upon exercise of the Warrant is subject to adjustment for splits, subdivisions or consolidations of shares and other standard dilutive events, or in the event the Company effects a reorganization, reclassification, merger, consolidation, disposition of assets, or other fundamental transaction. In addition, subject to certain exempt issuances, if at any time while the Warrant is outstanding, the Company sells, issues or grants any shares of Company common stock or other securities entitling the holder to acquire shares of Company common stock at a price per share less than the then exercise price, the exercise price shall be reduced to equal the lesser of either such lesser price or the volume-weighted average price on the next trading date following the first public disclosure of

the issuance. The Warrant includes a most favored nation clause providing that if the Company issues or sells any shares of common stock or any securities of the Company which would entitle the holder of such securities to acquire common stock on terms the holder reasonably believes are more favorable than those in the Warrant, at the request of the holder, the Company shall amend the Warrant to include such terms.
