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 lenders have a security interest in substantially all of the assets of the Company.

On August 6, 2026, the Company entered into a ninth amendment to the Credit Facility, which among other things, (i) extended the maturity date from December 12, 2028 to August 4, 2031; provided, that if any of the Convertible Notes (as defined below) remain outstanding (or were redeemed, repurchased, converted, or otherwise retired other than pursuant to one or more cashless (except for payments in cash for fees, expenses, and to avoid fractional shares not to exceed $250,000 in the aggregate) transactions) on the date that isninety-one (91) days prior to the then-current stated maturity of the Convertible Notes, and such date is earlier than August 4, 2031, then the Credit Facility shall mature on such earlier date, (ii) amended the definition of consolidated EBITDA, and (iii) amended the definition of suppressed availability.

The Company had $118,839,000 and $94,668,000 outstanding under the Revolving Facility at June 30, 2026 and March 31, 2026, respectively. In addition, $15,470,000 was outstanding for letters of credit at June 30, 2026. At June 30, 2026, after certain contractual adjustments, $93,302,000 was available under the Revolving Facility. The interest rate on the Company’s Revolving Facility was 6.83% and 6.79%, at June 30, 2026 and March 31, 2026, respectively.

The Credit Facility requires the Company to maintain; (i) a minimum fixed charge coverage ratio if undrawn availability is less than 22.5% of the aggregate revolving commitments and (ii) a specified minimum undrawn availability. During the three months ended June 30, 2026, undrawn availability was greater than the 22.5% threshold at all times, therefore, the fixed charge coverage ratio financial covenant was not required to be tested at any point during the fiscal quarter.

Convertible Notes, Related Party

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 2026, non-cash accrued interest on the Convertible Notes of $3,873,000 was paid in-kind and is included in the principal amount of Convertible Notes at June 30, 2026. The Convertible Notes have an initial conversion price of $15.00 per share of the Company’s common stock, subject to adjustment as provided in the Convertible Notes (“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. 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 June 30, 2026 and March 31, 2026, respectively.

The Company’s Convertible Notes are comprised of the following:

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, waszero at June 30, 2026 and March 31, 2026.

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 in the condensed consolidated balance sheets at June 30, 2026 and March 31, 2026. The fair value of the Conversion Option and the Company Redemption option using Level 3 inputs and the Monte Carlo simulation model was a liability of $20,600,000 and $16,900,000, and an asset of $12,720,000 and $10,560,000 at June 30, 2026 and March 31, 2026, respectively. During the three months ended June 30, 2026 and 2025, the Company recorded a loss of $1,540,000 and $1,790,000, 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 June 30, 2026 and March 31, 2026.

Interest expense related to the Convertible Notes is as follows:

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.

8. Contract Liabilities

Contract liabilities are comprised of the following:

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.

In connection with the remeasurement of these leases, the Company recorded a gain of $1,681,000 and $4,002,000 during the three months ended June 30, 2026 and 2025, respectively. These amounts are included in foreign exchange impact of lease liabilities and forward contracts in the condensed consolidated statements of operations.

Balance sheet information for leases is as follows:

Lease cost recognized in the condensed consolidated statements of operations is as follows:

Maturities of lease commitments at June 30, 2026, by fiscal year, were as follows:

Other information about leases is as follows:

10. Accounts Receivable Discount Programs

The Company uses accounts receivable discount programs offered by certain customers and their respective banks. Under these programs, the Company may sell those customers’ receivables to those banks at a discount to be agreed upon at the time the receivables are sold. These discount arrangements allow the Company to accelerate receipt of payment on customers’ receivables.

The following is a summary of accounts receivable discount 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. Commitments from participating financial institutions that are available to suppliers under this program were $40,000,000 as of June 30, 2026. 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 June 30, 2026 and March 31, 2026, the Company had $40,982,000 and $42,076,000, respectively, of outstanding supplier obligations confirmed as valid under this program, included inaccounts payable in the condensed consolidated balance sheets.

12. Net (Loss) Income per Share

Basic net (loss) income per share is computed by dividing net (loss) income by the weighted average number of shares of common stock outstanding during the period. Diluted net (loss) income per share includes the effect, if any, from the potential exercise or conversion of securities, such as stock options, Warrants, and Convertible Notes (as defined in Note 7), which would result in the issuance of incremental shares of common stock to the extent such impact is not anti-dilutive. Potential common shares that would have the effect of increasing diluted net income per share or decreasing diluted net loss per share are considered to be anti-dilutive and as such, these shares are not included in calculating diluted net (loss) income per share.

The following presents a reconciliation of basic and diluted net (loss) income per share:

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 June 30, 2026, the Warrants were not exercisable.

13. Income Taxes

The Company recorded income tax expense of $3,369,000, or an effective tax rate of (33.5)%, and $2,425,000, or an effective tax rate of 44.4%, for the three months ended June 30, 2026 and 2025, respectively. The effective tax rate for the three months ended June 30, 2026 was primarily impacted by the change in valuation allowance on certain jurisdictions' deferred tax assets resulting from current year activities and 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 continued to maintain valuation allowances on its U.S., one of its Mexican subsidiaries’, and one of its Canadian subsidiaries’ deferred tax assets. The Company will monitor its position in future periods. Should the actual amount differ from the Company’s estimates, the amount of any valuation allowance could be impacted.

The Company and its subsidiaries file income tax returns for the U.S. federal, various state, and foreign jurisdictions with varying statutes of limitations. At June 30, 2026, the Company remains subject to examination for fiscal years ended March 31, 2023 and forward. At June 30, 2026, the Company continues to be under examination in the U.S. by the Internal Revenue Service for fiscal year 2024. The Company is not under examination in any another jurisdiction. The Company believes no significant changes in the unrecognized tax benefits will occur within the next 12 months.

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 $44,085,000 and $43,076,000 at June 30, 2026 and March 31, 2026, respectively. These contracts generally have a term ofone 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:

The 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 cash flows for the three months ended June 30, 2026 and 2025. The fair value of the forward foreign currency exchange contracts of $768,000 and $852,000 is included in prepaid expenses and other current assets in the condensed consolidated balance sheets at June 30, 2026 and March 31, 2026, respectively.

15. Fair Value Measurements

The following summarizes financial assets and liabilities measured at fair value, by level within the fair value hierarchy:

Short-term Investments and Deferred Compensation

The Company’s short-term investments, which fund its deferred compensation liabilities, consist of investments in mutual funds. 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 June 30, 2026 and March 31, 2026. 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:

During the three months ended June 30, 2026, 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 June 30, 2026 and March 31, 2026, the net carrying amount of the Convertible Notes was $44,795,000 and $38,993,000, respectively (see Note 7). The estimated fair value of the Company’s Convertible Notes was $54,192,000 and $50,363,000 using Level 3 inputs at June 30, 2026 and March 31, 2026, respectively.

16. Share-based Payments

Stock Options

During the three months ended June 30, 2026 and 2025, no options to purchase shares of the Company’s common stock were granted.

The following is a summary of stock option transactions:

At June 30, 2026, options to purchase 43,245 shares of common stock were unvested at a weighted average exercise price of $9.32.

At June 30, 2026, there was $36,000 of total unrecognized compensation expense related to unvested stock option awards, which will be recognized over the weighted average remaining vesting period of approximately 0.2 years.

Restricted Stock Units (“RSUs”)

During the three months ended June 30, 2026 and 2025, the Company granted 386,555 and 428,552, respectively, of time-based vesting RSUs, based on the closing market price on the grant date.

The following is a summary of non-vested RSUs:

At June 30, 2026, there was $9,565,000 of unrecognized compensation expense related to RSUs, which will be recognized over the weighted average remaining vesting period of approximately 2.5 years.

Performance Stock Units (“PSUs”)

During the three months ended June 30, 2026 and 2025, the Company granted 309,289 and 353,778 PSUs (at target performance levels), respectively, based on the Company’s stock price or a total shareholder return (“TSR”) market conditions. All PSUs granted have athree-year performance period, subject to continued employment.

Stock Price PSUs

During the three months ended June 30, 2026, the Company granted 154,650 PSUs (at target performance levels), which vest as follows: (i) if the stock price is greater than or equal to $16.00 per share, then 1/3 of the grant will vest, (ii) if the stock price is greater than or equal to $18.00 per share then the next 1/3 of the grant will vest, and (iii) if the stock price is greater than or equal to $20.00 per share then the final 1/3 of the grant will vest. Recipients are eligible to vest in between 50% and 150% of the third tranche by achieving a stock price between $19.00 and $22.00 per share (each stock price target must be met forthirty consecutive trading days).

During the three months ended June 30, 2025, the Company granted 176,893 PSUs (at target performance levels), which vest as follows: (i) if the stock price is greater than or equal to $15.00 per share, then 1/3 of the grant will vest, (ii) if the stock price is greater than or equal to $17.00 per share then the next 1/3 of the grant will vest, and (iii) if the stock price is greater than or equal to $20.00 per share then the final 1/3 of the grant will vest. Recipients are eligible to vest in between 50% and 150% of the third tranche by achieving a stock price between $18.00 and $22.00 per share (each stock price target must be met forthirty consecutive trading days).

The Company calculated the fair value of these PSUs individually for each tranche using the Monte Carlo Simulation Model at the grant date. Compensation cost is recognized over the estimated derived service period. Compensation cost related to these awards will not be adjusted even if the market condition is not met.

TSR PSUs

During the three months ended June 30, 2026 and 2025, the Company granted 154,639 and 176,885 PSUs (at target performance levels), respectively, which cliff vest and the number of shares earned at the end of thethree-year performance period will vary, based only on actual performance, from 0% to 150% of the target number of PSUs granted, depending on the Company’s TSR percentile rank relative to that of a peer group over the performance period. TSR is measured based on a comparison of the closing price on the first trading day of the performance period and the average closing price over the last 30 trading days of the performance period. TSR is considered a market condition because it measures the Company’s return against the performance of the Russell 3000, excluding companies classified as financials and real estate and companies with a market capitalization of more than $600 million, as of the start of the performance period. Compensation cost is determined at the grant date and recognized on a straight-line basis over the requisite service period to the extent the conditions are deemed probable. Compensation cost related to the TSR award will not be adjusted even if the market condition is not met.

The fair value of PSUs subject to a market condition is determined using the Monte Carlo simulation model. The following table summarizes the assumptions used in determining the fair value of the awards subject to market conditions:

The following is a summary of non-vested PSUs:

At June 30, 2026, there was $7,462,000 of unrecognized compensation expense related to these awards, which will be recognized over the weighted average remaining vesting period of approximately 1.8 years.

17. Commitments and Contingencies

Warranty Returns

The Company allows its customers to return goods that their consumers have returned to them, whether or not the returned item is defective (“warranty returns”). The Company accrues an estimate of its exposure to warranty returns based on a historical analysis of the level of this type of return as a percentage of unit sales. Amounts charged to expense for these warranty returns are considered in arriving at the Company’s net sales.

The following summarizes the changes in the warranty returns:

At June 30, 2026 and March 31, 2026, the Company’s total warranty return accrual was $22,437,000 and $19,188,000, respectively, of which $10,444,000 and $7,479,000, respectively, was included in the customer returns RGA issued within accounts receivable—net and $11,993,000 and $11,709,000, respectively, was included in the customer finished goods returns accrual in the condensed consolidated balance sheets.

Contingencies

The Company is subject to various lawsuits and claims. In addition, government agencies and self-regulatory organizations have the ability to conduct periodic examinations of and administrative proceedings regarding the Company’s business, and its compliance with law, code, and regulations related to matters including, but not limited to, environmental, information security, taxes, levies, tariffs.
