Summary of Significant Accounting Policies

Note 2 — Summary of Significant Accounting Policies

Basis of Presentation

The Merger was accounted for as a reverse recapitalization of the Company because Legacy Mobix has been determined to be the accounting acquirer under ASC Topic 805 – Business Combinations. Under this method of accounting, Chavant is treated as the “acquired” company for financial reporting purposes. This determination was primarily based on holders of Legacy Mobix capital stock comprising a relative majority of the voting power of the Company upon consummation of the Merger and having the ability to nominate the majority of the governing body of the Company, Legacy Mobix senior management comprising the senior management of the Company, and Legacy Mobix operations comprising the ongoing operations of the Company. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Legacy Mobix with the Merger being treated as the equivalent of Legacy Mobix issuing shares for the net assets of Chavant, accompanied by a recapitalization. The net assets of Chavant were recognized as of the Closing at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Merger are presented as those of Legacy Mobix and the accumulated deficit of Legacy Mobix has been carried forward after Closing. All issued and outstanding securities of Chavant upon Closing were treated as issuances of securities of the Company upon the consummation of the Merger.

The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and include the accounts of Mobix Labs, Inc. and its subsidiaries. The Company’s fiscal year ends on September 30. Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements as of and for the year ended September 30, 2023 and the related notes which provide a more complete discussion of the Company’s accounting policies and certain other information. The September 30, 2023 condensed consolidated balance sheet was derived from the Company’s audited financial statements. These unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the Company’s condensed consolidated financial position as of March 31, 2024 and its condensed consolidated results of operations and cash flows for the periods ended March 31, 2024 and 2023. The condensed consolidated results of operations for the three months and six months ended March 31, 2024 are not necessarily indicative of the results to be expected for the fiscal year ending September 30, 2024 or for any other future annual or interim period.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements requires the Company to make estimates and assumptions that affect the reported amounts of certain assets and liabilities; the reported amounts of revenues and expenses for the periods covered and certain amounts disclosed in the notes to the condensed consolidated financial statements. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. As future events and their effects cannot be determined with precision, actual results could differ materially from those estimates and assumptions. Areas requiring significant estimates and assumptions by the Company include, but are not limited to:

●

valuation of stock-based compensation and equity-based awards;

●

valuation of common stock for periods prior to the Merger;

●

impairment assessments of goodwill and long-lived assets;

●

measurement of the earnout liability, the PIPE make-whole liability and other liabilities carried at fair value;

●

purchase price allocation and valuations of net assets acquired in business combinations; and,

●

provisions for income taxes and related valuation allowances and tax uncertainties.

Cash

As of March 31, 2024 and September 30, 2023, the Company’s cash balance consisted of demand deposits held at large financial institutions. The Company considers all highly liquid investments with a maturity of three months or less to be cash equivalents. The Company had no cash equivalents as of March 31, 2024 or September 30, 2023. The amount of deposits maintained at any financial institution may exceed federally insured limits. The Company places its cash with high credit quality financial institutions and has not experienced any losses on its deposits of cash.

Accounts Receivable, net

Accounts receivable are recorded at the invoiced amount and do not bear interest. For trade accounts receivable from customers, the Company performs ongoing credit evaluations of its customers and maintains an allowance for expected credit losses. The allowance for expected credit losses represents the Company’s best estimate based on current and historical information, and reasonable and supportable forecasts of future events and circumstances. Accounts receivable deemed uncollectible are charged against the allowance for expected credit losses when identified. The allowance for expected credit losses as of March 31, 2024 and September 30, 2023 and bad debt expense for the six months ended March 31, 2024 and 2023 were not material.

Inventory

Inventory is stated at the lower of cost, determined on a first-in, first-out basis, or net realizable value. Inventory costs consist of purchased materials, outside manufacturing costs, inbound freight and receiving costs, and capitalized overhead. The Company records an inventory reserve for losses associated with excess and obsolete items, based on available information and the Company’s current expectations of future demand, product obsolescence and market conditions. Any provision for excess and obsolete inventory is charged to cost of sales and is a permanent reduction of the carrying value of inventory. The reserve for excess and obsolete inventory as of March 31, 2024 and September 30, 2023 and write-downs of obsolete inventory for the six months ended March 31, 2024 and 2023 were not material.

Intangible Assets, net

The Company’s intangible assets principally consist of acquired developed technology and customer relationships and have finite lives ranging from one to fifteen years. The Company amortizes intangible assets over their useful lives on a straight-line basis, which the Company believes approximates the pattern in which the economic benefits of the intangible assets are expected to be utilized. To the extent that an acquired developed technology is incorporated in, or used to produce, a product the Company currently produces and sells, the related amortization expense is included in cost of revenue in the statements of operations and comprehensive loss. Amortization expense on other acquisition-related intangible assets is included in operating expenses.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets, consisting of property and equipment and intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company did not record any impairment losses on long-lived assets for the three months and six months ended March 31, 2024 and 2023.

Goodwill

Goodwill represents the excess of the fair value of purchase consideration of an acquired business over the fair value of the identifiable net assets acquired. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis on July 31, or more frequently if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company did not record any goodwill impairment losses for the three months and six months ended March 31, 2024 and 2023.

Business Combinations

The Company allocates the purchase price of an acquisition to the tangible assets acquired, liabilities assumed, and intangible assets acquired, based on their estimated fair values. The excess of the purchase price over the fair values of the net assets acquired is recorded as goodwill.

Accounting for business combinations requires that management make significant estimates and assumptions to determine the fair value of assets acquired and liabilities assumed at the acquisition date. Although management believes the assumptions and estimates to be reasonable and appropriate, they are inherently uncertain. Critical estimates in valuing certain acquired assets may include, but are not limited to, expected future cash flows including revenue growth rate assumptions from product sales, customer contracts and acquired technologies, expected costs to develop acquired technology into commercially viable products, estimated cash flows from the projects when completed, including assumptions associated with the technology migration curve and expected selling, general and administrative costs. The discount rates used to discount expected future cash flows to present value are typically derived from a weighted-average cost of capital analysis and are adjusted to reflect inherent risks. Unanticipated events and circumstances may occur that could affect either the accuracy or validity of such assumptions, estimates or actual results.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The Company uses a three-tiered hierarchy for inputs used in measuring fair value that emphasizes the use of observable inputs over the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are market participant assumptions based on market data obtained from sources independent of the Company. Unobservable inputs are the Company’s own assumptions of what market participants would use in pricing an asset or liability based on the best information available in the circumstances. The financial and nonfinancial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.

As a basis for considering such assumptions, a three-tier hierarchy is used in management’s determination of fair value based on the reliability and observability of inputs as follows:

Level 1 — Observable inputs that include quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 — Unobservable pricing inputs that are generally less observable from objective sources, such as discounted cash flow models or valuations.

Net Income (Loss) Per Share

Basic and diluted net income (loss) per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. Under the two-class method, net income (loss) is attributed to the Class A and Class B common stock and other participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed using the weighted-average number of shares and the effect of potentially dilutive securities outstanding during the period. For a period in which the Company reports a net loss, diluted net loss per share is the same as basic net loss per share because potentially dilutive common shares are not assumed to have been issued if their effect is antidilutive. See Note 18, Net Loss Per Share.

Comprehensive Loss

Comprehensive loss includes the Company’s net loss as well as other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. There were no differences between the Company’s net loss and comprehensive loss for the three months and six months ended March 31, 2024 and 2023.

Accounting Pronouncements Recently Adopted

The Company is an “emerging growth company,” as defined in the Securities Act. Under the Jumpstart Our Business Startups Act of 2012, an emerging growth company has the option to adopt new or revised accounting guidance either (i) within the same periods as otherwise applicable to public business entities, or (ii) within the same time periods as non-public business entities, including early adoption when permissible. With the exception of accounting guidance the Company elected to early adopt, when permissible, the Company has elected to adopt new or revised accounting guidance within the same time periods as non-public business entities.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments — Credit Losses (Topic 326) (“ASU 2016-13”), which provides guidance on measurement of credit losses on financial instruments. This ASU adds a current expected credit loss impairment model to GAAP that is based on expected losses rather than incurred losses whereby a broader range of reasonable and supportable information is required to be utilized in order to derive credit loss estimates. The Company adopted this guidance on a modified retrospective basis on October 1, 2023, with no material impact to the condensed consolidated financial statements.

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). ASU 2021-08 requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606 as if the acquiring entity had originated the contracts. The Company adopted this guidance on a prospective basis to business combinations occurring on or after October 1, 2023, with no material impact on its financial position or results of operations.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 expands segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The disclosures required under ASU 2023-07 are also required for public entities with a single reportable segment. The ASU is effective for the Company’s fiscal year beginning October 1, 2024 and for interim periods within the Company’s fiscal year beginning October 1, 2025, with early adoption permitted. The Company does not expect adoption of ASU 2023-07 will have a material impact on its financial position or results of operations.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The ASU is effective for the Company’s fiscal year beginning October 1, 2025. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company does not expect adoption of ASU 2023-09 will have a material impact on its financial position or results of operations.

In addition to the consideration paid at Closing, certain Legacy Mobix stockholders and certain holders of Legacy Mobix stock options (the “Earnout Recipients”) will be entitled to receive an additional aggregate 3,500,000 shares of Class A Common Stock issuable as earnout shares (the “Earnout Shares”) based on the achievement of trading price targets following the Closing and subject to the terms provided in the Business Combination Agreement. The Earnout Shares have a seven-year “Earnout Period,” commencing on the date that is the one year anniversary of the Closing, pursuant to which up to 1,750,000 shares of Class A Common Stock will be distributed to the Earnout Recipients if the VWAP of the Class A Common Stock exceeds $12.50 for any twenty trading days within a period of thirty consecutive trading days during the Earnout Period and an additional 1,750,000 shares of Class A Common Stock will be distributed to the Earnout Recipients if the VWAP of the Class A Common Stock exceeds $15.00 for any twenty trading days within a period of thirty consecutive trading days during the Earnout Period.

The Earnout Shares are accounted for as liability-classified instruments because the events that determine the number of Earnout Shares to which the Earnout Recipients will be entitled include events that are not solely indexed to the Company’s common stock. At the time of Closing, the Company estimated the aggregate fair value of its liability for the Earnout Shares using a Monte Carlo simulation model and recorded a liability of $33,559. As of March 31, 2024, none of the conditions for the issuance of any Earnout Shares had been achieved and the Company adjusted the carrying amount of the liability to its estimated fair value of $3,621. As a result of the decrease in the fair value of the liability, which is primarily the result of a decrease in the Company’s stock price between the Closing and March 31, 2024, the Company recognized non-cash gains of $5,174 and $29,938, respectively, for the three months and six months ended March 31, 2024, which are included in “Change in fair value of earnout liability” in the condensed consolidated statements of operations and comprehensive loss.

Make-Whole Shares

Pursuant to the PIPE Subscription Agreements, the Sponsor PIPE Subscription Agreement and the Amendment to Business Combination Marketing Agreement described above, Chavant agreed to issue additional shares of its Class A Common Stock (the “Make-Whole Shares”) to the PIPE Investors, the Sponsor and certain advisors with respect to 2,454,737 shares of the Company’s Class A Common Stock in the event that the VWAP per share of the Class A Common Stock during the thirty-day period (the “Adjustment Period”) commencing on the date that is thirty days after the date on which the PIPE resale registration statement is declared effective (the “Adjustment Period VWAP”) is less than $10.00 per share. In such case, the PIPE Investors will be entitled to receive a number of Make-Whole Shares equal to the number of shares of Class A Common Stock issued to the PIPE Investor multiplied by a fraction, the numerator of which is $10.00 minus the Adjustment Period VWAP and the denominator of which is the Adjustment Period VWAP. In the event that the Adjustment Period VWAP is less than $7.00, the Adjustment Period VWAP will be deemed to be $7.00.

The Make-Whole Shares are accounted for as liability-classified instruments because the events that determine the number of Make-Whole Shares issuable include events that are not solely indexed to the Company’s common stock. At the time of Closing, the Company estimated the aggregate fair value of its liability for the Make-Whole Shares using a Monte Carlo simulation model and recorded a liability of $2,071. As of March 31, 2024, the Make-Whole Shares had not been issued and the Company adjusted the carrying amount of the liability to its estimated fair value of $1,639. As a result of the decrease in the fair value of the liability, the Company recorded non-cash gains of $3,336 and $432, respectively, for the three months and six months ended March 31, 2024, which are included in “Change in fair value of PIPE make-whole liability” in the condensed consolidated statements of operations and comprehensive loss.

See Note 12, Fair Value Measurements, for additional information on the Company’s measurements with respect to the financial instruments issued in connection with the foregoing agreements.

Legacy Mobix incurred $6,363 of transaction costs in connection with the Merger, which was determined to be a capital-raising transaction for Legacy Mobix. At the time of the Closing, the Company allocated this amount between the equity-classified instruments and liability-classified instruments, based on their relative fair values, and recorded the $2,354 of costs associated with equity-classified instruments as a reduction of additional paid-in capital and charged the remaining $4,009 of costs associated with liability-classified instruments to expense. The Company also recognized a liability for unpaid transaction costs of Chavant totaling $3,090, which the Company recorded as a reduction of the proceeds of the Merger at the time of the Closing.

The following tables reconcile elements of the Merger to the Company’s condensed consolidated financial statements, and should be read in conjunction with the footnotes referenced above:

Warrants [Abstract]

Warrants

Note 4 — Warrants

Public and Private Warrants

In connection with its initial public offering, Chavant issued 6,000,000 Public Warrants and 3,400,000 Private Warrants (of which 400,000 Private Warrants were subsequently forfeited by the Sponsor), each of which entitles the holder to purchase one share of the Company’s Class A Common Stock at a price of $11.50 per share, subject to adjustments. The Public Warrants and Private Warrants are exercisable at any time commencing thirty days after the completion of the Merger and terminating five years after the completion of the Merger. The Company may redeem the Public Warrants at a price of $0.01 per warrant if the last reported sale of the Company’s Class A Common Stock equals or exceeds $18.00 per share for any twenty trading days within a thirty-day period after the Public Warrants become exercisable.

The Private Warrants are identical to the Public Warrants, except that the Private Warrants and shares of Class A Common Stock issuable upon the exercise of the Private Warrants are not transferable, assignable or salable until thirty days after the completion of the Merger, subject to certain limited exceptions. Additionally, the Private Warrants are exercisable on a cashless basis and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

Both the Public Warrants and Private Warrants are subject to adjustment if the Company issues additional equity securities for capital raising purposes at price (the “Newly Issued Price”) below specified levels; if the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds available for funding Merger at the Closing; and, if the VWAP of the Company’s Class A Common Stock during a specified period (“Market Value”) is below $9.20 per share. In such event, the exercise price of the warrants will be adjusted to be equal to 115% of the Market Value and the $18.00 per share redemption trigger price will be adjusted to be equal to 180% of the Newly Issued Price.

As a result of the issuances of shares under the PIPE Subscription Agreement and other agreements in connection with the Merger, the Company adjusted the exercise price of the warrants from $11.50 to $5.79 per share and adjusted the redemption trigger price from $18.00 to $9.06 per share. The Company recognized a noncash deemed dividend of $661 as a result of the warrant price adjustment.

Upon the Closing, the Company concluded that the Public Warrants meet the derivative scope exception for contracts in the Company’s own stock and recorded the Public Warrants in stockholders’ equity. The Company concluded that the Private Warrants do not meet the derivative scope exception and are accounted for as liabilities. Specifically, the Private Warrants contain provisions that affect the settlement amounts dependent upon the characteristics of the holder of the warrant, which is not an input into the pricing of a fixed-for-fixed option on equity shares. Therefore, the Private Warrants are not considered indexed to the Company’s stock and must be classified as a liability. At the time of Closing, the Company estimated the aggregate fair value of the Private Warrants using the Black-Scholes option-pricing model and recognized a liability of $150. As of March 31, 2024, all of the Private Warrants remained outstanding and the Company adjusted the carrying amount of the liability to its estimated fair value of $630. As a result of the increase in the fair value of the liability, the Company recorded non-cash losses of $420 and $480, respectively, for the three months and six months ended March 31, 2024, which are included in “Change in fair value of private warrants” in the condensed consolidated statements of operations and comprehensive loss.

PIPE Warrants

In connection with the PIPE Subscription Agreements, the Company issued the investors warrants to purchase shares of common stock at an exercise price of $0.01 per share. The Company evaluated these warrants and concluded that they meet the derivative scope exception for contracts in the Company’s own stock. Consequently, the PIPE warrants were recorded in stockholders’ equity.

Legacy Mobix Warrants

In connection with the Merger, all of Legacy Mobix’s outstanding warrants were assumed by the Company and converted into the same number of warrants to purchase shares of the Company’s Class A Common Stock, with no change to their exercise prices or other terms. Subsequent to the Merger, warrants to purchase an aggregate of 373,031 shares were exercised and converted into 369,671 shares of Class A Common Stock, with no cash proceeds to the Company.

During the six months ended March 31, 2024, Legacy Mobix issued warrants to purchase an aggregate of 51,020 shares of its common stock at $0.01 in connection with borrowings. See Note 11, Debt.

Also during the six months ended March 31, 2024, Legacy Mobix granted warrants to purchase an aggregate of 27,413 shares of common stock at a price of $0.01 per share to investors in connection with the sale of shares of its common stock. See Note 16, Equity.

As of March 31, 2024, the Company is obligated to issue warrants to purchase 130,000 shares of its Class A Common Stock at $0.01 per share to a service provider, in respect of services rendered to Legacy Mobix prior to the Merger. In addition, as described in Note 11, Debt, during the six months ended March 31, 2024 Legacy Mobix failed to repay the principal amount of a note payable by its maturity date and is obligated to issue warrants to purchase 103,000 shares of its Class A Common Stock at $0.01 per share to the lender as additional consideration. As of March 31, 2024, the Company has recorded a liability of $206 in the condensed consolidated balance sheet for the estimated fair value of the warrants. For the three months and six months ended March 31, 2024, the Company recognized a $526 gain from the change in the fair value of the liability, which is included in “Other non-operating losses, net” in the condensed consolidated statement of operations and comprehensive loss. The Company valued the warrants using a probability-weighted expected return model.

During the six months ended March 31, 2023, the Company issued warrants to purchase an aggregate of 300,000 shares of its common stock at $3.00 per share to non-service providers. In December 2022, the holders exercised these warrants and purchased 300,000 shares of the Company’s common stock for cash proceeds of $900. The Company also issued a warrant to purchase 400,000 shares of its common stock at $3.00 per share to a service provider. The Company recognized the $1,598 fair value of the warrant in selling, general and administrative expenses in the condensed consolidated statements of operations and comprehensive loss for the six months ended March 31, 2023. Effective March 2023, the warrant was cancelled.

See Note 12, Fair Value Measurements, for additional information on the Company’s measurements with respect to the warrants issued in connection with the foregoing transactions.

Equity [Abstract]

Equity

Note 16 — Equity

In connection with the Merger, the Company adopted its amended and restated certificate of incorporation and amended and restated bylaws. The amended and restated certificate of incorporation authorizes the issuance of preferred stock, Class A Common Stock and Class B Common Stock.

Common Stock

The Company is authorized to issue 285,000,000 shares of Class A Common Stock and 5,000,000 shares of Class B Common Stock. Holders of Class A and Class B common stock are each entitled to receive ratably any dividends or distributions as may be declared from time to time by the board of directors. Each class of common stock is subordinate to the Company’s preferred stock with respect to rights upon liquidation of the Company. Neither class of common stock is redeemable at the option of the holders. The holders of Class A and Class B common stock are entitled to vote together as a single class, with each holder of outstanding shares of Class A Common Stock entitled to one vote for each share of Class A Common Stock and each holder of outstanding shares of Class B Common Stock entitled to ten votes for each share of Class B Common Stock. Holders of shares of Class B Common Stock may elect at any time to convert each outstanding share of Class B Common Stock into one share of Class A Common Stock. Shares of Class B Common Stock are also subject to automatic conversion into shares of Class A Common Stock upon the occurrence of certain events or, if not previously converted, upon the seventh anniversary of the Closing.

During the six months ended March 31, 2024, Legacy Mobix sold 482,171 shares of its common stock at various dates in private placements for net proceeds of $3,286. In connection with the issuance of these shares, Legacy Mobix also granted one investor a warrant to purchase 27,413 shares of common stock at a price of $0.01 per share. The warrant is immediately exercisable and has a term of one year. The Company determined the warrant to be a freestanding equity instrument with no subsequent remeasurement. The Company determined the amount recognized within additional paid-in capital by allocating the proceeds received among the shares of common stock and the warrant issued based on their relative fair values.

During the six months ended March 31, 2023, the Legacy Mobix sold 993,364 shares of its common stock at various dates in private placements for net proceeds of $6,795.

As of March 31, 2024, the number of shares of Class A Common Stock available for issuance under the Company’s amended and restated articles of incorporation were as follows:

Authorized number of shares of Class A Common Stock			285,000,000
Class A Common Stock outstanding			23,600,558
Reserve for conversion of Class B Common Stock			2,254,901
Reserve for exercise of the Public Warrants and Private Warrants			9,000,000
Reserve for exercise of other common stock warrants outstanding or issuable			3,320,020
Shares issuable under PIPE make-whole provision			1,052,030
Reserve for earnout shares			3,500,000
Stock options and RSUs outstanding			8,601,088
Awards available for grant under 2023 Equity Incentive Plan			2,290,183
Awards available for grant under 2023 Employee Stock Purchase Plan			858,935
Common stock available for issuance			230,522,285

Preferred Stock

In connection with the Merger, all outstanding shares of Legacy Mobix Founders Redeemable Convertible Preferred Stock and Series A Redeemable Convertible Preferred Stock were cancelled and converted into 2,254,901 shares of the Company’s Class B Common Stock.

The amended and restated certificate of incorporation authorizes the Company to issue 10,000,000 shares of preferred stock, par value $0.00001, and the Company’s board of directors is authorized to designate one or more series of preferred stock, to fix the number of shares constituting any such series of preferred stock, and the powers, preferences and rights of any such series of preferred stock. Through March 31, 2024, the board of directors had not designated any such series of preferred stock and the Company had not issued any shares of preferred stock. As of March 31, 2024 no shares of preferred stock were outstanding.

The Company has never declared or paid any dividends on any class of its equity securities and does not expect to do so in the near future.

Committed Equity Facility

On March 18, 2024, the Company entered into a Purchase Agreement (“Purchase Agreement”) and a related Registration Rights Agreement with B. Riley Principal Capital II (“B. Riley”) which provides the Company the right, in its sole discretion, and subject to the satisfaction of the conditions set forth therein, to sell to B. Riley up to 9,500,000 newly issued shares of its Class A Common Stock (subject to certain limitations) from time to time. Any sales of Class A Common Stock pursuant to the Purchase Agreement, and the timing of any sales, are solely at the Company’s option, and the Company is under no obligation to sell any securities to B. Riley. The per share purchase price that B. Riley will pay for shares of Class A Common Stock will be determined by reference to the volume weighted average price of the Class A Common Stock measured over the regular trading session or intraday period of the trading session on Nasdaq on the date of each purchase, in each case as defined in the Purchase Agreement, less a three percent discount.

As consideration for B. Riley’s commitment to purchase shares of the Company’s Class A Common Stock, the Company agreed to pay a cash commitment fee in the amount of $1,500. B. Riley will withhold 30% in cash from the total aggregate purchase price until B. Riley has received the entire cash commitment fee. If any portion of the commitment fee remains unpaid on the earlier of the termination of the agreement or December 15, 2024, then the Company must pay B. Riley the remainder of the commitment fee in cash. The Company also agreed to reimburse B. Riley for reasonable legal fees and disbursements in an amount not to exceed $75 upon the execution of the Purchase Agreement and Registration Rights Agreement and $5 per fiscal quarter. In April 2024, the Company filed a registration statement with the Securities and Exchange Commission to register under the Securities Act, the offer and resale by B. Riley of up to 9,500,000 shares of Class A Common Stock that the Company may elect to sell to B. Riley pursuant to the Purchase Agreement.

As of March 31, 2024, the Company had not sold any shares under the Purchase Agreement. The amount and timing of the proceeds the Company receives from the sale of shares of Class A Common Stock pursuant to the Purchase Agreement, if any, will depend on a number of factors, including the numbers of shares the Company may elect to sell, the timing of such sales, the future market price of the Company’s Class A Common stock and the payment of the cash commitment fee. The cash commitment and other fees under the Purchase Agreement totaling $1,575 are included in “Other non-operating losses, net” in the condensed consolidated statement of operations and comprehensive loss for the three months and six months ended March 31, 2024.

Net Income (Loss) Per Share [Abstract]

Net Loss Per Share

Note 18 — Net Loss Per Share

The Company computes net loss per share of Class A and Class B Common Stock using the two-class method. Basic net loss per share is computed using the weighted-average number of shares outstanding during the period. Diluted net income loss per share is computed using the weighted-average number of shares and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities consist of stock options, warrants, RSUs and other contingently issuable shares. The dilutive effect of outstanding stock options, warrants, RSUs and other contingently issuable shares is reflected in diluted earnings per share by application of the more dilutive of (a) the two-class method or (b) the if-converted method and treasury stock method, as applicable. The computation of the diluted net income (loss) per share of Class A Common Stock assumes the conversion of Class B Common Stock, while the diluted net income (loss) per share of Class B Common Stock does not assume the conversion of those shares.

In periods where the Company has a net loss, most potentially dilutive securities are not included in the computation as their impact is anti-dilutive; those potentially dilutive securities whose impact is dilutive are included in the computation. For the three months and six months ended March 31, 2024, the PIPE make-whole liability and liability-classified warrants are included in the computation of diluted loss per share as if the underlying shares had been issued as of the later of the beginning of the fiscal period or the date of issuance of those securities. Inclusion of those securities under the if-converted method increases both the net loss for the period and the number of shares used in the per share computation and is dilutive to the Company’s net loss per share.

For the purposes of applying the if converted method or treasury stock method for calculating diluted earnings per share, the Public Warrants, Private Warrants, RSUs and stock options result in anti-dilution. Therefore, these securities are not included in the computation of diluted net loss per share. The Earnout Shares were not included for purposes of calculating the number of diluted shares outstanding because the number of dilutive shares is based on a conversion contingency associated with the VWAP of the Class A Common Stock which had not been met, and the contingency was not resolved, during the periods presented herein. The potential shares of Class A Common Stock that were excluded from the computation of diluted net income (loss) per share attributable to stockholders for the periods presented because including them would have an antidilutive effect were as follows:

Income Taxes

Note 15 — Income Taxes

The Company recorded a provision (benefit) for income taxes of $(16) and $1 for the three months ended March 31, 2024 and 2023, respectively, and a provision (benefit) for income taxes of $(1,296) and $32 for the six months ended March 31, 2024 and 2023, respectively. The provision (benefit) for income taxes for the three months and six months ended March 31, 2024 and 2023 was calculated using the discrete year-to-date method. In connection with the acquisition of EMI, the Company recognized an additional deferred tax liability of $1,386 associated with acquired intangible assets. Based on the availability of these tax attributes, the Company determined that it expects to realize a greater portion of its existing deferred tax assets and for the six months ended March 31, 2024 the Company recognized an income tax benefit of $1,296, principally resulting from a reduction in the valuation allowance on its deferred tax assets. For the six months ended March 31, 2023, the Company’s provision for income taxes differs from an amount calculated based on statutory tax rates principally due to the Company recording a valuation allowance against the net operating losses it generated during the period. The Company establishes a valuation allowance when necessary to reduce the carrying amount of its deferred tax assets when it is more likely than not that the deferred tax assets will not be realized. In evaluating the Company’s ability to realize deferred tax assets, the Company considers all available positive and negative evidence, including historical operating results, potential limitations on the Company’s ability to carry forward net operating losses, ongoing tax planning, and forecasts of future taxable income on a jurisdiction-by-jurisdiction basis. Based on these factors, the Company has established a valuation allowance to reduce its net deferred tax assets to the amount that is more likely than not to be realized.

Acquisition of EMI Solutions, Inc.

Acquisition of EMI Solutions, Inc. [Abstract]

Acquisition of EMI Solutions, Inc.

Note 5 — Acquisition of EMI Solutions, Inc.

On December 18, 2023, the Company completed the acquisition of EMI Solutions when the Company acquired all of the issued and outstanding common shares of EMI Solutions, which is accounted for as a business combination. EMI Solutions is a manufacturer of electromagnetic interference filtering products for military and aerospace applications. The Company believes the acquisition of EMI Solutions will complement its existing product offerings, expand its customer base and allow it to deliver solutions that address a wider variety of applications and markets.

Consideration for the acquisition consisted of 964,912 shares of the Company’s common stock with an estimated fair value of $8,856 and $2,200 in cash. Of the cash portion of the consideration, the Company paid $155 at the time of the consummation of the acquisition and subsequently paid an additional $1,000. The remaining $1,045 cash portion of the consideration is payable in quarterly installments of $174 through June 2025.

The merger agreement with EMI Solutions provided that in the event that Legacy Mobix did not complete an initial public offering (including the Merger) within twenty-four months following the completion of the acquisition of EMI Solutions, the sellers could require the Company to pay all unpaid cash consideration and provided the sellers a “put right” wherein the sellers could require that the Company repurchase the 964,912 shares of common stock for a cash amount equal to $6.84 per share. The Company evaluated the terms of the related agreement and concluded that the shares of common stock issued as consideration were contingently redeemable common stock, and required recognition as temporary equity, because the events that determine whether the Company will be required to repurchase the 964,912 shares of its common stock for cash are not within the Company’s control. At the time of completion of the acquisition, the Company estimated the fair value of the contingently redeemable common stock at $8,856, based upon the fair value of the Legacy Mobix common stock, adjusted to include the fair value of the put right. The Company estimated the fair value of the put right using the Black-Scholes option pricing model with the following assumptions: expected volatility of 55.0%; no expected dividend yield; risk-free interest rate of 4.5%; and a contractual term of two years. The Company included this amount as part of the value of the purchase consideration. After the Closing of the Merger with Chavant on December 21, 2023, the common stock was no longer contingently redeemable, and the Company reclassified the value of the contingently redeemable common stock to permanent equity at its carrying value of $8,856, with no gain or loss recognized.

Purchase consideration:
Contingently redeemable common stock issued to seller	$	8,856

	$	10,897

The Company estimated the useful life of customer relationships is fifteen years, the useful life of the trade name is two years and the useful life of the backlog is one year. The goodwill is primarily attributed to expected synergies for the combined operations and is not deductible for income tax purposes.

The operating results of EMI Solutions are included in the Company’s condensed consolidated financial statements for periods subsequent to the acquisition date. The amounts of revenues and net loss of EMI Solutions included in the Company’s condensed consolidated statement of operations and comprehensive loss for the six months ended March 31, 2024 were $997 and $454, respectively.

Fair Value Measurements

As a basis for considering such assumptions, a three-tier hierarchy is used in management’s determination of fair value based on the reliability and observability of inputs as follows:

Level 1 — Observable inputs that include quoted prices in active markets for identical assets or liabilities.

Level 3 — Unobservable pricing inputs that are generally less observable from objective sources, such as discounted cash flow models or valuations.

Leases [Abstract]

Leases

Note 13 — Leases

The Company has entered into operating leases for office space. The leases have remaining terms ranging from three months to 3.4 years and expire at various dates through August 2027. The leases do not contain residual value guarantees or restrictive covenants. The lease covering the Company’s 19,436 square foot headquarters in Irvine, California provides the Company an option to extend the lease for one additional five-year term, with rent at the then prevailing market rate. The lease requires a security deposit of $400, which is recorded in other assets in the condensed consolidated balance sheets.

The following lease costs are included in the condensed consolidated statement of operations and comprehensive loss:

	Six months ended March 31,
	2024		2023

Operating lease cost	$	200	$	202
Short-term lease cost		46		155
Total lease cost	$	246	$	357

Cash paid for amounts included in the measurement of operating lease liabilities for the six months ended March 31, 2024 and 2023 was $273 and $264, respectively. As of March 31, 2024, the weighted-average remaining lease term was 3.4 years, and the weighted-average discount rate was 15.6%. The Company did not obtain any right-of-use assets in exchange for new operating or financing lease liabilities during the six months ended March 31, 2024. There were no leases that had not yet commenced as of March 31, 2024 that will create significant additional rights and obligations for the Company.

The following table reconciles the undiscounted cash flows to the operating lease liabilities recorded on the condensed consolidated balance sheet as of March 31, 2024:

Fair Value Measurements [Abstract]

Fair Value Measurements

Note 12 — Fair Value Measurements

The carrying amounts of the Company’s cash, accounts receivable and accounts payable approximate their fair value due to the short-term nature of these instruments. The Company believes the aggregate carrying value of debt approximates its fair value as of March 31, 2024 and September 30, 2023 because the notes payable, the 7% promissory notes - related parties, the notes payable - related parties and the convertible notes each mature or were converted within one year of the respective balance sheet dates.

Fair Value Hierarchy

Liabilities measured at fair value on a recurring basis as of March 31, 2024 are as follows:

	Level 1		Level 2		Level 3		Total

Earnout liability	$	—	$	—	$	3,621	$	3,621
PIPE make-whole liability		—		—		1,639		1,639
Private Warrants and other warrants		—		—		836		836

Total	$	—	$	—	$	6,096	$	6,096

The Company classifies the earnout liability, the PIPE make-whole liability, the Private Warrants and other warrants and the SAFEs as Level 3 financial instruments due to the judgment required to develop the assumptions used and the significance of those assumptions to the fair value measurement. No financial instruments were transferred between levels of the fair value hierarchy during the six months ended March 31, 2024 or March 31, 2023. The following table provides a reconciliation of the balance of financial instruments measured at fair value on a recurring basis using Level 3 inputs:

Six months ended March 31, 2024:	Earnout Liability			PIPE Make-Whole Liability			Private Warrants and Other Warrants			SAFEs

Balance, September 30, 2023	$	—		$	—		$	—		$	1,512
Liabilities recognized		33,559			2,071			882			—
Conversion to Class A Common Stock in the Merger		—			—			—			(1,522	)
Change in fair value included in net loss		(29,938	)		(432	)		(46	)		10

Balance, March 31, 2024	$	3,621		$	1,639		$	836		$	—

Six months ended March 31, 2023:	SAFEs

Balance, September 30, 2022	$	1,983
Change in fair value included in net loss		558

Balance, March 31, 2023	$	2,541

Earnout Liability

The Company estimates the fair value of the earnout liability using a Monte Carlo simulation model that utilizes significant assumptions, including volatility, expected term and risk-free rate that determine the probability of achieving the earnout conditions. The following table summarizes the assumptions used in estimating the fair value of the earnout liability at the respective dates:

	December 21, 2023 (Closing)			March 31, 2024

Stock price	$	10.66		$	2.01
Expected volatility		50	%		60	%
Risk-free rate		3.9	%		4.1	%
Contractual term		8 years			7.7 years

PIPE Make-Whole Liability

The Company uses a Monte Carlo simulation model that utilizes significant assumptions, including volatility, expected term and risk-free rate, to estimate the fair value of the PIPE make-whole liability. The following table summarizes the assumptions used in estimating the fair value of the PIPE make-whole liability at the respective dates:

	December 21, 2023 (Closing)			March 31, 2024

Stock price	$	10.17		$	1.56
Expected volatility		49	%		51	%
Risk-free rate		5.4	%		5.4	%
Contractual term		4 months			3 months

Equity Incentive Plans [Abstract]

Equity Incentive Plans

Note 17 — Equity Incentive Plans

In connection with the Merger, the Company adopted of 2023 Equity Incentive Plan, which provides for the issuance of stock options, restricted stock awards, RSUs and other stock-based compensation awards to employees, directors, officers, consultants or others who provide services to the Company. The specific terms of such awards are to be established by the board of directors or a committee thereof. The Company has reserved 2,290,183 shares of its Class A Common Stock for issuance under the terms of the 2023 Equity Incentive Plan. As of March 31, 2024, the Company had not issued any awards under this plan.

Also in connection with the Merger, the Company adopted the 2023 Employee Stock Purchase Plan to assist eligible employees in acquiring stock ownership in the Company. Under the 2023 Employee Stock Purchase Plan, eligible employees may elect to enroll in the plan, designate a portion of eligible compensation to be withheld by the Company during an offering period, and purchase shares of the Company’s Class A Common Stock at the end of such offering period. The price of the shares purchased shall not be less than 85% of the fair market value of a share on the enrollment date or on the purchase date, whichever is lower. The Company has reserved 858,935 shares of its Class A Common Stock for issuance under the terms of the 2023 Employee Stock Purchase Plan. As of March 31, 2024, the Company had not commenced any offering period nor sold any shares under this plan.

Prior to the Merger, Legacy Mobix had three equity incentive plans which provided for the issuance of stock-based compensation awards and immediately prior to the Merger, Legacy Mobix RSUs and stock options were outstanding under these plans. Under the terms of the 2023 Equity Incentive Plan, no further awards may be made under the Legacy Mobix equity incentive plans.

Restricted Stock Units

In connection with the Merger, all of Legacy Mobix’s RSUs were assumed by the Company and converted into an RSU covering the same number of shares of the Company’s Class A Common Stock.

In November 2022, Legacy Mobix and certain of its officers and key employees agreed to enter into amended RSU agreements relating to an aggregate of 10,000,000 RSUs and in March 2023 and May 2023, Legacy Mobix and certain of its officers and key employees agreed to forfeit the 10,000,000 RSUs. The RSUs to these officers and key employees were replaced with a commitment from the Company, contingent upon closing of the Merger, to issue an aggregate of 5,000,000 RSUs (of which 1,000,000 were modified to common stock warrants upon the holder’s termination of employment) over three years, beginning on the first anniversary of the Closing of the Merger. Because the vesting of these awards was subject to both a service condition and a performance condition (the completion of the Merger), the Company determined that vesting of the awards was not probable and did not recognize any stock-based compensation expense for these awards prior to the Closing.

Upon Closing, the performance condition was satisfied, and vesting of the awards is subject only to a service condition. As a result, the Company is required to recognize the value of these awards over the requisite service period. During the six months ended March 31, 2024, the Company recognized stock-based compensation expense of $11,846 relating to these RSUs and warrants, which includes a catch-up for the portion of the service period completed prior to the performance condition being satisfied. Also during the six months ended March 31, 2024, in connection with a separation of employment, the Company modified 1,000,000 RSUs held by an employee such that the RSUs—which were subject to forfeiture under their original terms—would continue to vest over their original service period. Because the fair value of the modified awards was lower than the grant-date fair value of the original awards, the Company recognized a $2,242 reduction of stock-based compensation expense during the three months ended March 31, 2024.

During the six months ended March 31, 2023, certain employees agreed to forfeit 670,000 RSUs with no current replacement award. As a result, the Company recognized $3,706 of additional stock-based compensation expense in the six months ended March 31, 2023.

A summary of activity in the Company’s RSUs for the six months ended March 31, 2024 is as follows:

	Number of units			Weighted-Average Grant Date Fair Value per Unit

Outstanding at September 30, 2023		209,494		$	6.84
Performance-based RSUs		3,999,999		$	8.65
Vested		(130,934	)	$	6.84
Outstanding at March 31, 2024		4,078,559		$	8.61

No RSUs vested during the six months ended March 31, 2023. Unrecognized compensation expense related to RSUs was $33,946 as of March 31, 2024 and is expected to be recognized over a weighted-average period of 3.8 years.

Stock Options

In connection with the Merger, all Legacy Mobix stock options were assumed by the Company and converted into the same number of stock options of the Company, with no change to their exercise prices, vesting conditions or other terms. Stock option activity for the six months ended March 31, 2024 is as follows:

	Number of Options			Weighted- Average Exercise Price per Share		Weighted- Average Remaining Contractual Term (years)
Outstanding at September 30, 2023		5,905,684		$	4.28
Granted		32,200		$	6.84
Exercised		(474,313	)	$	5.91
Forfeited		(941,042	)	$	6.53
Outstanding at March 31, 2024		4,522,529		$	3.66		6.3
Exercisable at March 31, 2024		4,041,704		$	3.29		6.1

The terms of stock option awards permit a “net share settlement” for exercises of stock options, at the Company’s discretion. Stock options exercised during the six months ended March 31, 2024 include options to purchase an aggregate of 474,313 shares which were exercised and settled for 198,115 shares of Class A Common Stock, with no cash proceeds to the Company.

Unrecognized stock-based compensation expense related to stock options, totaling $1,911 as of March 31, 2024, is expected to be recognized over a weighted-average period of 2.0 years. The aggregate intrinsic value of stock options outstanding and stock options exercisable as of March 31, 2024 was $3,626 and $3,626, respectively. The total intrinsic value of options exercised during the six months ended March 31, 2024 and 2023 was $1,938 and $0, respectively. The total fair value of options that vested during the six months ended March 31, 2024 and 2023 was $1,221 and $1,887, respectively.

The weighted-average grant date fair value of options granted during the six months ended March 31, 2024 and 2023 was $3.50 and $3.58, respectively. The fair value of stock options granted was estimated with the following assumptions:

	Six months ended March 31,
	2024						2023
	Range						Range
	Low			High			Low			High

Expected volatility		54.8	%		55.6	%		52.4	%		53.6	%

Risk-free interest rate		3.9	%		4.4	%		3.6	%		4.2	%
Expected term (years)		4.5			5.3			5.0			5.8

The condensed consolidated statements of operations and comprehensive loss include stock-based compensation expense as follows:

Agreement to Acquire RaGE Systems, Inc.

On May 8, 2024, the Company entered into an agreement (the “RaGE Business Combination Agreement”) to acquire RaGE Systems, Inc. (“RaGE Systems”) for aggregate consideration of $12,000. RaGE Systems specializes in developing products for 5G communications, mmWave imaging, and software defined radio targeting the commercial, industrial, and defense and aerospace sectors.

As consideration for the acquisition, the Company will issue the sellers a number of shares of its Class A Common Stock equal to the quotient of (a) $10,000 divided by (b) the VWAP (as defined in the RaGE Business Combination Agreement) of Mobix Class A Common Stock for the fifteen trading days up to and including the fifth business day prior to the closing date. In addition, the Company will pay the sellers an aggregate of $2,000 in cash, of which $200 will be payable on the closing date; $1,000 will be payable on November 15, 2024 and $800 will be payable on April 15, 2025. The Company will also enter into employment agreements with each of the RaGE stockholders. Pursuant to the RaGE Business Combination Agreement, the RaGE stockholders will also be entitled to receive possible earn-out payments of up to $8,000 over eight fiscal quarters, payable in a combination of cash and shares of the Company’s Class A Common Stock, based upon the satisfaction of certain financial metrics and continued employment with the Company. The RaGE Business Combination Agreement also provides the RaGE stockholders with “piggy-back” registration rights, subject to certain requirements and customary conditions. Consummation of the acquisition is subject to the satisfaction or waiver of customary closing conditions, including the satisfactory completion of the Company’s due diligence investigation, set forth in the RaGE Business Combination Agreement.

Notes Payable

During the six months ended March 31, 2024, the Company entered into two promissory notes payable having an aggregate principal amount of $250 with unrelated investors to meet its working capital needs. The notes bear interest at rates ranging from 6% to 76% per annum. One note having an original principal amount of $150 matures in November 2024, requires weekly principal payments of $4 and is guaranteed by an officer and director of the Company. The other note, having a principal amount of $100, is unsecured, matured in January 2024 and was repaid by the Company in February 2024.

In connection with the issuance of one of the notes, the Company issued the purchaser a warrant to purchase an aggregate of 47,020 shares of its common stock at $0.01. The warrant has a contractual term of twelve months and is immediately exercisable. The Company evaluated the warrant and determined that it met all the requirements for equity classification under ASC 815. The Company accounted for the warrant as a detachable warrant at its fair value, using the relative fair value method. The portion of the proceeds allocated to the warrant of $79 was recorded as an increase to additional paid-in capital and as a discount to notes payable on the condensed consolidated balance sheet. The Company is amortizing the discount over the term of the related note using the effective interest method. The Company valued the warrant at the time of issuance using the Black-Scholes option pricing model with the following assumptions: expected volatility of 55.6%; no expected dividend yield; risk-free interest rate of 5.3%; and a contractual term of twelve months.

One note, issued in September 2023 and having a principal amount of $531, provided that in the event the Company failed to pay the principal amount by its October 5, 2023 maturity date, the Company must issue the purchaser as additional consideration a warrant to purchase 28,000 shares of its common stock for the first calendar month, and warrants to purchase an additional 25,000 shares for each successive calendar month, during which the note remained unpaid. The Company did not repay the note by its maturity date and the Company is currently obligated to issue the purchaser warrants to purchase an aggregate of 103,000 shares of its common stock. The warrants are immediately exercisable and have an exercise price of $0.01 per share. In January 2024, the Company repaid this note in full.

During the six months ended March 31, 2023, the Company entered into five promissory notes payable having an aggregate principal amount of $1,100 with unrelated investors to meet its working capital needs. The notes matured at various dates through March 2024. During the six months ended March 31, 2023, the Company repaid $350 under one of these notes. In connection with the issuance of the notes, the Company gave the purchasers warrants to purchase an aggregate of 35,464 shares of its common stock at an exercise price of $0.01 per share. One promissory note also provided that in the event the Company failed to pay the principal amount on the maturity date, the Company must issue the purchaser a warrant to purchase an additional 15,000 shares of its common stock for each seven-day period thereafter until such time as the principal is repaid in full. Through March 31, 2023, the Company had issued the purchaser additional warrants to purchase an aggregate of 165,000 shares of its common stock.

As of March 31, 2024, promissory notes payable having a remaining principal balance of $400 were outstanding and are included in “Notes payable” in the condensed consolidated balance sheet.

7% Promissory Notes — Related Parties

The Company has two outstanding promissory notes with related parties which the Company assumed in 2020 as part of an asset acquisition. The promissory notes bear interest at 7% per annum, are unsecured and do not require principal payments prior to the maturity date. The notes had an initial maturity date of August 2022, but were amended in May 2022 to extend their maturity to July 2023. During the six months ended March 31, 2024 the Company made principal payments of $586 on one of the notes and as of March 31, 2024 an aggregate principal amount of $2,763 remains outstanding. The 7% promissory notes are included in “Notes payable — related parties” in the condensed consolidated balance sheet.

Notes Payable — Related Parties

As of September 30, 2023, two notes payable—related parties having an aggregate principal balance of $444 were outstanding. During the six months ended March 31, 2024, the Company repaid each of the notes in full.

During the six months ended March 31, 2023, the Company issued a promissory note having a principal balance of $106 to an employee of the Company, and repaid the note in full.

SAFEs

In connection with the Merger, all of the outstanding SAFEs, representing an original purchase amount of $1,000, were converted into 150,953 shares of the Company’s Class A Common Stock and the $1,512 carrying amount of these SAFEs was credited to equity, with no gain or loss recognized. As of March 31, 2024, no SAFEs remain outstanding.

The Company remeasured the SAFEs to fair value at each reporting date. For the six months ended March 31, 2024 and 2023, the Company recorded increases in the fair value of the SAFEs of $10 and $50, respectively. The change in fair value of the SAFEs is reported in “Change in fair value of SAFEs” in the condensed consolidated statements of operations and comprehensive loss.

Convertible Notes

During the six months ended March 31, 2024, the Company issued convertible notes having an aggregate principal amount of $200 to unaffiliated investors. The convertible notes matured in February 2024, bore interest at 16% per annum, were unsecured and had a conversion price of $6.84 per share. The principal amount of the convertible notes and any accrued interest thereon was convertible into shares of the Company’s common stock, at the election of each holder, at any time prior to maturity. In connection with the issuance of the convertible notes, the Company issued the investors warrants to purchase an aggregate of 4,000 shares of Legacy Mobix common stock at an exercise price of $0.01 per share. The warrants are immediately exercisable and have a one-year term. In connection with the Merger, all outstanding convertible notes were converted into 30,045 shares of the Company’s Class A Common Stock and the $206 carrying amount of the notes and accrued interest thereon was credited to equity, with no gain or loss recognized. As of March 31, 2024, no convertible notes remain outstanding.
