Debt [Abstract]
Debt	7. Debt The Company has $268,620,000 in senior secured financing, (as amended from time to time, the “Credit Facility”) consisting of a $238,620,000 revolving loan facility (the “Revolving Facility”), subject to certain restrictions, and a $30,000,000 term loan facility (the “Term Loans”). The Term Loans were repaid during the year ended March 31, 2024. The Credit Facility matures on December 12, 2028. The lenders have a security interest in substantially all of the assets of the Company. In June 2024, the Company enrolled in a feature with its lenders, under which the Company sweeps its cash collections to pay down its Revolving Facility and borrows on-demand to fund payments. This feature is expected to reduce interest expense on borrowings under the Credit Facility. The Company had $124,691,000 and $128,000,000 outstanding under the Revolving Facility at September 30, 2024 and March 31, 2024, respectively. In addition, $7,047,000 was outstanding for letters of credit at September 30, 2024. At September 30, 2024, after certain contractual adjustments, $94,330,000 was available under the Revolving Facility. The interest rate on the Company’s Revolving Facility was 8.17% and 8.43%, at September 30, 2024 and March 31, 2024, respectively. The Credit Facility requires the Company to maintain a minimum fixed charge coverage ratio if undrawn availability is less than 22.5% of the aggregate revolving commitments and a specified minimum undrawn availability. During the six months ended September 30, 2024 Convertible Notes On March 31, 2023, the Company entered into a note purchase agreement, as amended, (the “Note Purchase Agreement”) with Bison Capital Partners VI, L.P. and Bison Capital Partners VI-A, L.P. (collectively, the “Purchasers”) and Bison Capital Partners VI, L.P., as the purchaser representative (the “Purchaser Representative”) for the issuance and sale of $32,000,000 in aggregate principal amount of convertible notes due in 2029 (the “Convertible Notes”), which was used for general corporate purposes. The Convertible Notes bear interest at a rate of 10.0% per annum, compounded annually, and payable (i) in-kind or (ii) in cash, annually in arrears on April 1 of each year, commencing on April 1, 2024. In April 2024, non-cash accrued interest on the Convertible Notes of $3,209,000 was paid in-kind and is included in the principal amount of Convertible Notes at September 30, 2024. The Convertible Notes have an initial conversion price of $15.00 per share of common stock (“Conversion Option”). Unless and until the Company delivers a redemption notice, the Purchasers of the Convertible Notes may convert their Convertible Notes at any time at their option. Upon conversion, the Convertible Notes will be settled in shares of the Company’s common stock. Except in the case of the occurrence of a fundamental transaction, as defined in the form of convertible promissory note, the Company may not redeem the Convertible Notes prior to March 31, 2026. After March 31, 2026, the Company may redeem all or part of the Convertible Notes for a cash purchase (the “Company Redemption”) price. The effective interest rate was 18.3% as of September 30, 2024 and March 31, 2024, respectively. The Company’s Convertible Notes are comprised of the following: September 30, 2024 March 31, 2024 Principal amount of Convertible Notes $ 35,209,000 $ 32,000,000 Less: unamortized debt discount attributed to Compound Net Derivative Liability (7,089,000 ) (7,576,000 ) Less: unamortized debt discount attributed to debt issuance costs (990,000 ) (1,058,000 ) Carrying amount of the Convertible Notes 27,130,000 23,366,000 Plus: Compound Net Derivative Liability 5,210,000 7,410,000 Net carrying amount of Convertible Notes, related party $ 32,340,000 $ 30,776,000 In connection with the Note Purchase Agreement, the Company entered into common stock warrants (the “Warrants”) with the Purchasers, which mature on March 30, 2029. The fair value of the Warrants, using Level 3 inputs and the Monte Carlo simulation model, was zero at September 30, 2024 and March 31, 2024. The Company Redemption option has been combined with the Conversion Option as a compound net derivative liability (the “Compound Net Derivative Liability”). The Compound Net Derivative Liability has been recorded within convertible note, related party During the three months ended September 30, 2024 and 2023, the Company recorded losses of $380,000 and $390,000, respectively, as the change in fair value of the Compound Net Derivative Liability in the condensed consolidated statement of operations. During the six months ended September 30, 2024 and 2023, the Company recorded a gain of $2,200,000 and a loss of $530,000, respectively, as the change in fair value of the Compound Net Derivative Liability in the condensed consolidated statements of operations and condensed consolidated statements of cash flows. The Convertible Notes also contain additional features, such as, default interest and options related to a fundamental transaction, which were not separately accounted for as the value of such features were not material at September 30 Interest expense related to the Convertible Notes is as follows: Three Months Ended Six Months Ended September 30, September 30, 2024 2023 2024 2023 Contractual interest expense $ 880,000 $ 800,000 $ 1,760,000 $ 1,600,000 Accretion of debt discount 249,000 208,000 487,000 409,000 Amortization of debt issuance costs 35,000 30,000 68,000 57,000 Total interest expense $ 1,164,000 $ 1,038,000 $ 2,315,000 $ 2,066,000 There are no future payments required under the Convertible Notes prior to their maturity, therefore, the principal amount of the Convertible Notes plus interest payable in-kind, assuming no early redemption or conversion has occurred, of $56,704,000 would be paid on March 30, 2029.

Leases [Abstract]
Leases	9. Leases The Company leases various facilities in North America and Asia under operating leases expiring through August 2033. The Company has material nonfunctional currency leases that could have a material impact on the Company’s condensed consolidated statements of operations. As required for other monetary liabilities, lessees remeasure foreign currency-denominated lease liabilities using the exchange rate at each reporting date, but the lease assets are nonmonetary assets measured at historical rates and are not affected by subsequent changes in the exchange rates. During the six months ended September 30, 2024, the Company ceased manufacturing operations at its Torrance, California facility as a part of its on-going strategy to utilize its global footprint to enhance its operating efficiencies. This represented a significant change to the use of this right-of-use asset, which required a reassessment of the Company’s asset groups. The Company concluded that this right-of-use asset was no longer part of the Hard Parts asset group. The Company performed a test for recoverability (using Level 3 inputs) which resulted in no impairment at September 30, 2024. Any future changes to the assumptions and estimates from those anticipated may affect the carrying value of right-of-use assets and could result in impairment charges. Balance sheet information for leases is as follows: Leases Classification September 30, 2024 March 31, 2024 Assets: Operating Operating lease assets $ 71,792,000 $ 83,973,000 Finance Plant and equipment 3,634,000 4,611,000 Total leased assets $ 75,426,000 $ 88,584,000 Liabilities: Current Operating Operating lease liabilities $ 9,272,000 $ 8,319,000 Finance Other current liabilities 1,331,000 1,585,000 Long-term Operating Long-term operating lease liabilities 69,419,000 72,240,000 Finance Other liabilities 1,451,000 1,893,000 Total lease liabilities $ 81,473,000 $ 84,037,000 Lease cost recognized in the condensed consolidated statements of operations is as follows: Three Months Ended Six Months Ended September 30, September 30, 2024 2023 2024 2023 Lease cost Operating lease cost $ 3,523,000 $ 3,761,000 $ 7,282,000 $ 7,503,000 Short-term lease cost 381,000 350,000 693,000 643,000 Variable lease cost 91,000 146,000 255,000 332,000 Finance lease cost: Amortization of finance lease assets 295,000 391,000 653,000 794,000 Interest on finance lease liabilities 45,000 57,000 96,000 119,000 Total lease cost $ 4,335,000 $ 4,705,000 $ 8,979,000 $ 9,391,000 Maturities of lease commitments at September 30, 2024 by fiscal year were as follows: Maturity of lease liabilities Operating Leases Finance Leases Total 2025 $ 6,753,000 $ 819,000 $ 7,572,000 2026 13,575,000 1,055,000 14,630,000 2027 11,711,000 564,000 12,275,000 2028 11,147,000 401,000 11,548,000 2029 11,142,000 203,000 11,345,000 Thereafter 43,524,000 17,000 43,541,000 Total lease payments 97,852,000 3,059,000 100,911,000 Less amount representing interest (19,161,000 ) (277,000 ) (19,438,000 ) Present value of lease liabilities $ 78,691,000 $ 2,782,000 $ 81,473,000 Other information about leases is as follows: September 30, 2024 March 31, 2024 Lease term and discount rate Weighted-average remaining lease term (years): Finance leases 2.8 2.8 Operating leases 7.7 8.3 Weighted-average discount rate: Finance leases 6.6 % 6.4 % Operating leases 5.8 % 5.8 %

Supplier Finance Programs	11. Supplier Finance Programs The Company utilizes a supplier finance program, which allows certain of the Company’s suppliers to sell their receivables due from the Company to participating financial institutions at the sole discretion of both the supplier and the financial institutions. The program is administered by a third party. As of September 30, 2024, $15,000,000 of commitments from participating financial institutions is available to suppliers under this program. The Company has no economic interest in the sale of these receivables and no direct relationship with the financial institution. Payments to the third-party administrator are based on services rendered and are not related to the volume or number of financing agreements between suppliers, financial institution, and the third-party administrator. The Company is not a party to agreements negotiated between participating suppliers and the financial institution. The Company’s obligations to its suppliers, including amounts due and payment terms, are not affected by a supplier’s decision to participate in this program. The Company does not provide guarantees and there are no assets pledged to the financial institution or the third-party administrator for the committed payment in connection with this program. At September 30, 2024, the Company had $26,487,000 of outstanding supplier obligations confirmed as valid under this program, included in accounts payable and accrued liabilities

For the three and six months ended September 30, 2024 and 2023, there were 2,357,749 and 2,104,035, respectively, of potential common shares not included in the calculation of diluted net loss per share because their effect was anti-dilutive. In addition, for the three and six months ended September 30, 2024 and 2023, there were 2,435,281 and 2,240,593, respectively, of potential common shares not included in the calculation of diluted net loss per share under the “if-converted” method for the Convertible Notes because their effect was anti-dilutive. The potential common shares related to the Warrants issued in connection with the Convertible Notes (see Note 7) are anti-dilutive until they become exercisable and as of September 30, 2024, the Warrants were not exercisable.

Income Taxes [Abstract]
Income Taxes	13. Income Taxes The Company recorded an income tax expense of $912,000, or an effective tax rate of (44.7)%, compared with an income tax benefit of $46,000, or an effective tax rate of 2.3%, for the three months ended September 30, 2024 and 2023, respectively. The Company recorded an income tax expense of $734,000, or an effective tax rate of (3.6)%, compared with an income tax benefit of $55,000, or an effective tax rate of 1.6%, for the six months ended September 30, 2024 and 2023, respectively. The effective tax rate for the three and six months ended September 30, 2024, was primarily impacted by (i) the change in valuation allowance, (ii) specific jurisdictions that the Company does not expect to recognize the benefit of losses, and (iii) foreign income taxed at rates that are different from the federal statutory rate. Management continues to monitor its valuation allowance position in its various jurisdictions. In assessing the need for a valuation allowance, the Company considers all positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, past financial performance, and tax planning strategies. Based on this analysis, the Company determined that it is more likely than not that certain deferred tax assets will not be realized. As a result, the Company maintained its valuation allowance. The Company will continue to monitor the need for a valuation allowance in future periods, considering any changes in circumstances that may affect the realizability of deferred tax assets. The Company and its subsidiaries file income tax returns for the U.S. federal, various state, and foreign jurisdictions with varying statutes of limitations. The Company was previously under examination by the State of California for fiscal years ended March 31, 2020, 2021 and 2022. During the three months ended September 30, 2024, this audit was concluded with no changes required to the Company’s filed income tax returns. At September 30, 2024, the Company remains subject to examination from the fiscal years ended March 31, 2020 and forward. The Company believes no significant changes in the unrecognized tax benefits will occur within the next 12 months.

Financial Risk Management and Derivatives [Abstract]
Financial Risk Management and Derivatives	14. Financial Risk Management and Derivatives Purchases and expenses denominated in currencies other than the U.S. dollar, which are primarily related to the Company’s overseas facilities, expose the Company to market risk from material movements in foreign exchange rates between the U.S. dollar and the foreign currencies. The Company’s primary risk exposure is from fluctuations in the value of the Mexican peso and to a lesser extent the Chinese yuan. To mitigate these risks, the Company enters into forward foreign currency exchange contracts to exchange U.S. dollars for these foreign currencies. The extent to which forward foreign currency exchange contracts are used, is modified periodically in response to the Company’s estimate of market conditions and the terms and length of anticipated requirements. The Company enters into forward foreign currency exchange contracts in order to reduce the impact of foreign currency fluctuations and not to engage in currency speculation. The use of derivative financial instruments allows the Company to reduce its exposure to the risk that the eventual cash outflow resulting from funding the expenses of the foreign operations will be materially affected by changes in exchange rates between the U.S. dollar and the foreign currencies. The Company does not hold or issue financial instruments for trading purposes. The Company designates forward foreign currency exchange contracts for forecasted expenditure requirements to fund foreign operations. The Company had forward foreign currency exchange contracts with a U.S. dollar equivalent notional value of $53,039,000 and $54,092,000 at September 30, 2024 and March 31, 2024, respectively. These contracts generally have a term of one year or less, at rates agreed at the inception of the contracts. The counterparty to these derivative transactions is a major financial institution with investment grade credit rating; however, the Company is exposed to credit risk with this institution. The credit risk is limited to the potential unrealized gains (which offset currency fluctuations adverse to the Company) in any such contract should this counterparty fail to perform as contracted. Any changes in the fair values of forward foreign currency exchange contracts are included in foreign exchange impact of lease liabilities and forward contracts in the condensed consolidated statements of operations. The following shows the effect of derivative instruments on the condensed consolidated statements of operations: Foreign Exchange Impact of Lease Liabilities and Forward Contracts Three Months Ended Six Months Ended Derivatives Not Designated as September 30, September 30, Hedging Instruments 2024 2023 2024 2023 Loss from forward foreign currency exchange contracts $ (1,450,000 ) $ (2,812,000 ) $ (6,819,000 ) $ (2,312,000 ) The fair value of the forward foreign currency exchange contracts of $4,303,000 is included in other current liabilities in the condensed consolidated balance sheets at September 30, 2024.

These investments are classified as Level 1 as the shares of these mutual funds trade with sufficient frequency and volume to enable the Company to obtain pricing information on an ongoing basis. Forward Foreign Currency Exchange Contracts The forward foreign currency exchange contracts are primarily measured based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers (See Note 14) . Compound Net Derivative Liability The Company estimates the fair value of the Compound Net Derivative Liability (see Note 7) using Level 3 inputs and the Monte Carlo simulation model at the balance sheet date. The Monte Carlo simulation model requires the input of subjective assumptions including the expected volatility of the underlying stock. These subjective assumptions are based on both historical and other information. Changes in the values assumed and used in the model can materially affect the estimate of fair value. This amount is recorded within convertible notes, related party in the condensed consolidated balance sheets at September 30, 2024 and March 31, 2024. Any changes in the fair value of the Compound Net Derivative Liability are recorded in change in fair value of compound net derivative liability in the condensed consolidated statements of operations and condensed consolidated statements of cash flows. The following assumptions were used to determine the fair value of the Compound Net Derivative Liability: September 30, 2024 March 31, 2024 Risk free interest rate 3.55 % 4.36 % Cost of equity 22.00 % 23.20 % Weighted average cost of capital 13.10 % 14.90 % Expected volatility of the Company’s common stock 45.00 % 50.00 % EBITDA volatility 40.00 % 40.00 % The following summarizes the activity for Level 3 fair value measurements: Three Months Ended Six Months Ended September 30, September 30, 2024 2023 2024 2023 Beginning balance $ 4,830,000 $ 8,570,000 $ 7,410,000 $ 8,430,000 Changes in fair value of Compound Net Derivative Liability included in earnings 380,000 390,000 (2,200,000 ) 530,000 Ending balance $ 5,210,000 $ 8,960,000 $ 5,210,000 $ 8,960,000 During the three and six months ended September 30, 2024, the Company had no significant measurements of assets or liabilities at fair value on a nonrecurring basis subsequent to their initial recognition. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the short-term nature of these instruments. The carrying amounts of the revolving loan and other long-term liabilities approximate their fair value based on the variable nature of interest rates and current rates for instruments with similar characteristics. At September 30, 2024 and March 31, 2024, the net carrying amount of the Convertible Notes was $32,340,000 and $30,776,000, respectively ( see Note 7). The estimated fair value of the Company’s Convertible Notes was $37,631,000 and $38,276,000 using Level 3 inputs at September 30, 2024 and March 31, 2024, respectively.
