Summary of Significant Accounting Policies [Abstract]
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 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 financial position as of December 31, 2023 and its results of operations and cash flows for the three months ended December 31, 2023 and 2022. The results of operations for the three months ended December 31, 2023 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 December 31, 2023 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 December 31, 2023 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 December 31, 2023 and September 30, 2023 and bad debt expense for the three months ended December 31, 2023 and 2022 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 materials purchase costs, 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. 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 ended December 31, 2023 and 2022. 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 ended December 31, 2023 and 2022. 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 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 Income (Loss) Per Share. Comprehensive Income (Loss) Comprehensive income (loss) includes the Company’s net income (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 income (loss) and comprehensive income (loss) for the three months ended December 31, 2023 and 2022. 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) In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers 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 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. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures

Non-Redemption Agreement On December 20, 2023, Chavant and Mobix Labs entered into a non-redemption agreement with a shareholder of Chavant, pursuant to which the shareholder agreed to withdraw its redemption of 73,706 ordinary shares of Chavant (“Ordinary Shares”) prior to the Merger. In consideration therefor, Mobix Labs issued the shareholder a warrant to purchase 202,692 shares of Legacy Mobix common stock at an exercise price of $0.01 per share, exercisable upon the Closing. The warrant was exercised at the Closing and, following net settlement into 202,489 shares of Legacy Mobix Common Stock, converted into 202,489 shares of Class A Common Stock of the Company in connection with the Closing. Amendment to Business Combination Marketing Agreement On December 21, 2023, Chavant entered into an amendment to the Business Combination Marketing Agreement, dated as of July 19, 2021 between Chavant and certain advisors wherein the parties agreed to resolve their differences with respect to marketing fees contemplated by the agreement and the advisors agreed to receive, in lieu of any cash payment of fees or reimbursement of expenses, an aggregate of 280,000 shares of Class A Common Stock. The number of shares is subject to adjustment through the issuance of additional shares of Class A Common Stock in the event that the VWAP of the Class A Common Stock is less than $10.00 over a specified period. See “ Make-Whole Shares Earnout Shares 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 December 31, 2023, 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 $8,795. The gain resulting from the $24,764 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 December 31, 2023, is included in “Change in fair value of earnout liability” in the condensed consolidated statements of operations and comprehensive income (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 December 31, 2023, the Make-Whole Shares had not been issued and the Company adjusted the carrying amount of the liability to its estimated fair value of $4,975. The loss resulting from the $2,904 increase in the fair value of the liability is included in “Change in fair value of PIPE make-whole liability” in the condensed consolidated statements of operations and comprehensive income (loss). See Note 12, Fair Value Measurements 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: Shares Chavant public shares, net of redemptions 111,005 Chavant founder shares, net of shares forfeited 1,341,369 PIPE investors’ shares 1,975,000 Settlement of PIPE warrant 199,800 Sponsor PIPE subscription 199,737 Settlement of Sponsor Warrant 272,182 Settlement of warrant to non-redeeming shareholder 202,489 Amendment to Business Combination Marketing Agreement 280,000 Total Chavant shares outstanding immediately prior to the Merger 4,581,582 Legacy Mobix rollover shares 18,139,258 Conversion of Legacy Mobix convertible notes 30,045 Conversion of Legacy Mobix SAFEs 150,953 Total number of Class A common shares issued in the Merger 22,901,838 Closing proceeds: Proceeds from Chavant trust fund $ 1,264 Proceeds from PIPE investment 19,750 Closing disbursements: Legacy Mobix Merger-related transaction costs (3,747 ) Chavant Merger-related transaction costs (2,219 ) Net cash proceeds from the Merger at Closing 15,048 Mobix Merger-related transaction costs paid prior to closing (983 ) Net cash proceeds 14,065 Non-cash activity: Conversion of Legacy Mobix convertible notes to Class A Common Stock 206 Conversion of Legacy Mobix SAFEs to Class A Common Stock 1,522 Conversion of Legacy Mobix redeemable convertible preferred stock to Class B Common Stock 2,300 Unpaid Merger-related transaction costs assumed from Chavant (871 ) Unpaid Merger-related transaction costs of Legacy Mobix (1,633 ) Merger-related transaction costs expensed 4,009 Liability-classified instruments: Fair value of earnout liability (33,559 ) Fair value of PIPE make-whole liability (2,071 ) Fair value of Private Warrants (150 ) Net equity impact of the Merger $ (16,182 )

Warrants

Warrants	Dec. 31, 2023
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. 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 December 31, 2023, the warrants remained outstanding and the Company adjusted the carrying amount of the liability to its estimated fair value of $210. The loss resulting from the $60 increase in the fair value of the liability is included in “Change in fair value of private warrants” in the condensed consolidated statements of operations and comprehensive income (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 three months ended December 31, 2023, 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 three months ended December 31, 2023, 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 December 31, 2023, 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 In October and December 2022, 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. In December 2022, the Company 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 income (loss) for the three months ended December 31, 2022. Effective March 2023, the warrant was cancelled. See Note 12, Fair Value Measurements

Acquisition of EMI

Acquisition of EMI [Abstract]
Acquisition of EMI	Note 5 — Acquisition of EMI On December 18, 2023, the Company completed the acquisition of EMI when the Company acquired all of the issued and outstanding common shares of EMI, which is accounted for as a business combination. EMI is a manufacturer of electromagnetic interference filtering products for military and aerospace applications. The Company believes the acquisition of EMI 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, $155 was paid at the time of the consummation of the acquisition and $1,000 is payable within thirty days following the Closing of the Merger, with the remainder payable in equal quarterly installments of $174 beginning March 31 2024. The EMI merger agreement 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, 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. The following table summarizes the amount of the aggregate purchase consideration and the preliminary allocation to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values, of which the valuation of intangible assets is subject to finalization: Purchase consideration: Contingently redeemable common stock issued to seller $ 8,856 Cash consideration (at present value) 2,041 $ 10,897 Allocation: Cash $ 45 Accounts receivable 387 Inventory 155 Other current assets 7 Property and equipment 107 Other assets 30 Intangible asset—customer relationships 6,100 Intangible asset—backlog 300 Intangible asset—trade name 100 Goodwill 5,542 Accounts payable (227 ) Accrued expenses (263 ) Deferred tax liability (1,386 ) $ 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 are included in the Company’s condensed consolidated financial statements for periods subsequent to the acquisition date. The amounts of revenues and net income (loss) of EMI included in the Company’s condensed consolidated statement of operations and comprehensive income (loss) for the three months ended December 31, 2023 were not material. The following table shows unaudited pro forma revenues and net income (loss) of the Company, as if the acquisition of EMI had been completed as of October 1, 2022.

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 One outstanding note, issued in September 2023 and having a principal amount of $531, provides that in the event the Company fails 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 remains 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 78,000 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. As of December 31, 2023, promissory notes payable having a remaining principal balance of $1,559 were outstanding and are included in “Notes payable” at a carrying amount of $1,503 (net of unamortized discount of $56) in the condensed consolidated balance sheet. 7% Promissory Notes — Related Parties The Company has two outstanding promissory notes with related parties having an aggregate remaining principal amount of $3,349, 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. The 7% promissory notes are included in “Notes payable — related parties” in the condensed consolidated balance sheet. Subsequent to December 31, 2023, the Company has not made any principal payments on these notes, and the $3,349 principal remains outstanding. Notes Payable — Related Parties During the three months ended December 31, 2023, the Company repaid one note having a principal balance of $344. As of December 31, 2023, one note having an aggregate principal balance of $100 remained outstanding and is included in “Notes payable — related parties” in the condensed consolidated balance sheet. 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 December 31, 2023, no SAFEs remain outstanding. The Company remeasures the SAFEs to fair value at each reporting date. For the three months ended December 31, 2023 and 2022, 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 income (loss). Convertible Notes During the three months ended December 31, 2023, 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 December 31, 2023, no convertible notes remain outstanding.

Fair Value Measurements	Dec. 31, 2023
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 December 31, 2023 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 converted within one year of the respective balance sheet dates. Fair Value Hierarchy Liabilities measured at fair value on a recurring basis as of December 31, 2023 are as follows: Level 1 Level 2 Level 3 Total Earnout liability $ — $ — $ 8,795 $ 8,795 PIPE make-whole liability — — 4,975 4,975 Private Warrants and other warrants — — 843 843 Total $ — $ — $ 14,613 $ 14,613 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.

Leases [Abstract]
Leases	Note 13 — Leases The Company has entered into operating leases for office space. The leases have remaining terms ranging from six months to 3.7 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 income (loss): Three months ended 2023 2022 Operating lease cost $ 100 $ 101 Short-term lease cost 2 80 Total lease cost $ 102 $ 181 Cash paid for amounts included in the measurement of operating lease liabilities for the three months ended December 31, 2023 and 2022 was $136 and $132, respectively. As of December 31, 2023, the weighted-average remaining lease term was 3.6 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 three months ended December 31, 2023. There were no leases that had not yet commenced as of December 31, 2023 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 December 31, 2023: Years ending September 30, 2024 (remaining nine months) $ 401 2025 526 2026 545 2027 515 Total minimum lease payments 1,987 Less: imputed interest (466 ) Present value of future minimum lease payments 1,521 Less: current obligations under leases (325 ) Long-term lease obligations $ 1,196

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 14 — Commitments and Contingencies Noncancelable Purchase Commitments The Company has unconditional purchase commitments for services which extend to various dates through September 2024. Future minimum payments under these unconditional purchase commitments as of December 31, 2023 totaled $984. Loss Contingency In fiscal year 2021, the Company recognized a liability for a contingent loss related to a business acquisition. The Company estimated the amount of the liability at $8,434, which was accrued in the condensed consolidated balance sheet as of September 30, 2022. In January 2023, the Company issued 1,233,108 shares of its common stock in settlement of this liability. Litigation From time to time, the Company may become subject to legal proceedings, claims and litigation arising in the ordinary course of business. The Company does not believe it is currently a party to any material legal proceedings, nor is the Company aware of any other pending or threatened litigation that the Company believes would have a material adverse effect on the Company’s business, operating results, cash flows or financial condition should such litigation be resolved unfavorably. Indemnifications In the ordinary course of business, the Company often includes standard indemnification provisions in its arrangements with customers, suppliers and vendors. Pursuant to these provisions, the Company may be obligated to indemnify such parties for losses or claims suffered or incurred in connection with its service, breach of representations or covenants, intellectual property infringement or other claims made against such parties. These provisions may limit the time within which an indemnification claim can be made. The Company has not in the past incurred significant expense defending against third party claims, nor has it incurred significant expense under its standard service warranties or arrangements with its customers, suppliers and vendors. Accordingly, the Company has not recognized any liabilities for these indemnification provisions as of December 31, 2023 or September 30, 2023.

Income Taxes [Abstract]
Income Taxes	Note 15 — Income Taxes The Company recorded a provision (benefit) for income taxes of $(1,280) and $31 for the three months ended December 31, 2023 and 2022, respectively. The provision (benefit) for income taxes for the three months ended December 31, 2023 and 2022 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 three months ended December 31, 2023 the Company recognized an income tax benefit of $1,280 for the resulting reduction in the valuation allowance on its deferred tax assets. For the three months ended December 31, 2022, 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.

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 three months ended December 31, 2023, 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 three months ended December 31, 2022, the Company sold 773,889 shares of its common stock at various dates in private placements for net proceeds of $5,295. As of December 31, 2023, 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 23,544,492 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 3,295,020 Shares issuable under PIPE make-whole provision 1,052,030 Reserve for earnout shares 3,500,000 Stock options and RSUs outstanding 9,513,647 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 229,690,792 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 December 31, 2023, 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 December 31, 2023 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.

Equity Incentive Plans	Dec. 31, 2023
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 December 31, 2023, 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 December 31, 2023, 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 is subject to both a service condition and a performance condition (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 three months ended December 31, 2023, the Company recognized stock-based compensation expense of $10,858 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. A summary of activity in the Company’s RSUs for the three months ended December 31, 2023 is as follows: Number Weighted-Average Outstanding at September 30, 2023 209,494 $ 6.84 Performance-based RSUs 4,000,000 $ 10.58 Vested (104,748 ) $ 6.84 Cancelled — $ — Outstanding at December 31, 2023 4,104,746 $ 10.48 No RSUs vested during the three months years ended December 31, 2022. Unrecognized compensation expense related to RSUs was $33,628 as of December 31, 2023 and is expected to be recognized over a weighted-average period of 3.9 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 three months ended December 31, 2023 is as follows: Number Weighted-Average Weighted-Average Outstanding at September 30, 2023 5,905,684 $ 4.28 Granted 32,200 $ 6.84 Exercised (390,440 ) $ 5.80 Expired (138,543 ) $ 5.99 Outstanding at December 31, 2023 5,408,901 $ 4.14 7.4 Exercisable at December 31, 2023 4,055,326 $ 3.29 7.0 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 three months ended December 31, 2023 include options to purchase an aggregate of 390,440 shares which were exercised and settled for 168,235 shares of Class A Common Stock, with no cash proceeds to the Company. Unrecognized stock-based compensation expense related to stock options, totaling $4,963 as of December 31, 2023, is expected to be recognized over a weighted-average period of 2.3 years. The aggregate intrinsic value of stock options outstanding and stock options exercisable as of December 31, 2023 was $7,587 and $7,587, respectively. The total intrinsic value of options exercised during the three months ended December 31, 2023 and 2022, was $1,639 and $0, respectively. The total fair value of options that vested during the three months ended December 31, 2023 and 2022 was $903 and $785, respectively. The weighted-average grant date fair value of options granted during the three months ended December 31, 2023 and 2022 was $3.50 and $3.60, respectively.

Net Income (Loss) Per Share	Dec. 31, 2023
Net Income (Loss) Per Share [Abstract]
Net Income (Loss) Per Share	Note 18 — Net Income (Loss) Per Share The Company computes net income (loss) per share of Class A and Class B Common Stock using the two-class method. Basic net income (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, the weighted-average number of shares used in the computation of diluted net loss per share is the same as for basic net loss per share due to the fact that when a net loss exists, dilutive securities are not included in the computation as their impact is anti-dilutive. Three months ended 2023 2022 Class A Class B Common Basic net income (loss) per share: Numerator: Allocation of net income (loss) $ 834 $ 101 $ (9,390 ) Denominator: Weighted-average shares outstanding 18,617,656 2,254,901 12,379,480 Basic net income (loss) per share $ 0.04 $ 0.04 $ (0.76 ) Diluted net income (loss) per share: Numerator: Allocation of net income (loss) $ 834 $ 101 $ (9,390 ) Reallocation of net income as a result of conversion of Class B to Class A Common Stock 101 — — Reallocation of net income — (11 ) — Allocation of net income (loss) 935 90 (9,390 ) Denominator: Number of shares used in basic earnings per share calculation 18,617,656 2,254,901 12,379,480 Conversion of Class B to Class A Common Stock 2,254,901 — — Dilutive effect of stock options, warrants and RSUs 2,443,514 — — Number of shares used in per share computation 23,316,071 2,254,901 12,379,480 Diluted net income (loss) per share $ 0.04 $ 0.04 $ (0.76 ) For the purposes of applying the if converted method or treasury stock method for calculating diluted earnings per share, the Public Warrants, Private Placement Warrants, the Make-Whole Shares, and stock options result in anti-dilution. Therefore, these securities are not included in the computation of diluted net income (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: Three months ended 2023 2022 Public Warrants and Private Warrants 9,000,000 — Make-whole shares 1,052,030 — Earnout shares 3,500,000 — RSUs — 10,984,241 Stock options 1,690,476 6,400,758 Convertible preferred stock (on an as-converted basis) — 2,254,901 Common stock warrants — 400,000 Convertible notes — 131,072 15,242,506 20,170,972

Summary of Significant Accounting Policies [Abstract]
Basis of Presentation	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 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 financial position as of December 31, 2023 and its results of operations and cash flows for the three months ended December 31, 2023 and 2022. The results of operations for the three months ended December 31, 2023 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	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	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	Cash As of December 31, 2023 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 December 31, 2023 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, 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 December 31, 2023 and September 30, 2023 and bad debt expense for the three months ended December 31, 2023 and 2022 were not material.
Inventory	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 materials purchase costs, 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.
Intangible Assets, net	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	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 ended December 31, 2023 and 2022.
Goodwill	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 ended December 31, 2023 and 2022.
Business Combinations	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 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.
