In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This standard was issued in response to the SEC’s disclosure update and simplification initiative, which affects a variety of topics within the Accounting Standards Codification. The amendments apply to all reporting entities within the scope of the affected topics unless otherwise indicated. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures.
Improvements to Income Tax Disclosures
 
In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (Topic 740). This standard requires the Company to provide further disaggregated income tax disclosures for specific categories on the effective tax rate reconciliation, as well as additional information about federal, state/local and foreign income taxes. The standard also requires the Company to annually disclose its income taxes paid (net of refunds received), disaggregated by jurisdiction. This guidance is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is to be applied prospective basis, although optional retrospective application is permitted. The Company will adopt this standard as of March 31, 2026, and is currently evaluating the impact this guidance will have on its financial statement disclosures. The Company expects its consolidated financial statements as of March 31, 2026 to include the expanded income tax disclosures required by the standard.
 
Disaggregation of Income Statement Expenses
 
In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (“DISE”) (Subtopic 220-40). This standard requires the Company to disclose, in the footnotes at each interim and annual reporting period, information about expenses by the nature of the expense in addition to certain disclosures about selling expenses. Entities are required to include the following relevant expense captions: (i) purchase of inventory, (ii) employee compensation, (iii) depreciation, (iv) intangible asset amortization, and (v) depreciation, depletion and amortization recognized as part of oil and gas producing activities. In January 2025, the FASB issued ASU No. 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) Clarifying the Effective Date, which is intended to clarify the effective date of ASU No. 2024-03. As clarified in ASU 2025-01, the new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures.
 
Debt with Conversion and Other Options
 
In November 2024, the FASB issued ASU 2024-04, Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, which seeks to clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. This guidance is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures.
 
Measurement of Credit Losses
 
In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides a practical expedient that all entities can use when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under ASC 606, Revenue from Contracts with Customers. Under this practical expedient, an entity is allowed to assume that the current conditions it has applied in determining credit loss allowances for current accounts receivable and current contract assets remain unchanged for the remaining life of those assets. This guidance is effective for annual periods beginning after December 15, 2025, including interim reporting periods within those fiscal years, with early adoption permitted. Entities that elect the practical expedient and, if applicable, make the accounting policy election are required to apply the amendments prospectively. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and disclosures.
 
Internal-Use Software
 
In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which amends the recognition and disclosure guidance for internal-use software costs, removing the previous software development stage model with a probable-to-complete recognition threshold. This guidance is effective for annual periods beginning after December 15, 2027, including interim reporting periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and disclosures.
Interim Reporting
 
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270) Narrow-Scope Improvements, which improves the navigability of the guidance in ASC 270, Interim Reporting, and clarifies when it applies. Under this guidance, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. This guidance is effective for annual periods beginning after December 15, 2027, including interim reporting periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and disclosures.
 
Codification Improvements
 
In December 2025, the FASB issued ASU 2025-12, Codification Improvements, which addresses suggestions received from stakeholders regarding the Accounting Standards Codification and makes other incremental improvements to GAAP. The update represents changes to the Accounting Standards Codification that clarify, correct errors in or make other improvements to a variety of topics that are intended to make it easier to understand and apply. This guidance is effective for annual periods beginning after December 15, 2026, including interim reporting periods within those fiscal years, with early adoption permitted. Entities are required to apply the amendments to ASC 260 retrospectively. All other amendments may be applied prospectively or retrospectively. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and disclosures.

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.
The Company had $88,010,000 and $90,787,000 outstanding under the Revolving Facility at December 31, 2025 and March 31, 2025, respectively. In addition, $15,470,000 was outstanding for letters of credit at December 31, 2025. At December 31, 2025, after certain contractual adjustments, $128,583,000 was available under the Revolving Facility. The interest rate on the Company’s Revolving Facility was 6.97% and 7.46%, at December 31, 2025 and March 31, 2025, 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 nine months ended December 31, 2025, undrawn availability was greater than the 22.5% threshold, therefore, the fixed charge coverage ratio financial covenant was not required to be tested.
 
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 2025, non-cash accrued interest on the Convertible Notes of $3,521,000 was paid in-kind and is included in the principal amount of Convertible Notes at December 31, 2025. 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. 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 December 31, 2025 and March 31, 2025, respectively.
 
The Company’s Convertible Notes are comprised of the following:
 
    December 31, 2025     March 31, 2025  
Convertible Notes, related party
         
Principal amount of Convertible Notes
 $38,730,000   $35,209,000

  7,610,000    7,470,000 
Net carrying amount of Convertible Notes, related party  $39,890,000   $35,207,000 
 
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 December 31, 2025 and March 31, 2025.
 
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 December 31, 2025 and March 31, 2025. 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 $19,600,000 and $9,000,000, and an asset of $11,990,000 and $1,530,000 at December 31, 2025 and March 31, 2025, respectively. During the three months ended December 31, 2025 and 2024, the Company recorded a gain of $3,910,000 and $260,000, respectively, as the change in fair value of the Compound Net Derivative Liability in the condensed consolidated statements of operations. During the nine months ended December 31, 2025 and 2024, the Company recorded a loss of $140,000 and a gain of $2,460,000, 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 December 31, 2025 and March 31, 2025.

Total interest expense on Convertible Notes
 $1,324,000   $1,177,000   $3,926,000   $3,492,000 
 
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
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 $1,183,000 and a loss of $1,875,000 during the three months ended December 31, 2025 and 2024, respectively, and a gain of $6,652,000 and a loss of $11,562,000 during the nine months ended December 31, 2025 and 2024, respectively. These amounts are included in foreign exchange impact of lease liabilities and forward contracts in the condensed consolidated statements of operations.
During the year ended March 31, 2025, the Company ceased manufacturing operations at its Torrance, California facility as a part of its strategy 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 December 31, 2025. 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.

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. Commitments from participating financial institutions that are available to suppliers under this program were $40,000,000 as of December 31, 2025. 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 December 31, 2025 and March 31, 2025, the Company had $32,632,000 and $33,661,000, respectively, of outstanding supplier obligations confirmed as valid under this program, included in accounts payable in the condensed consolidated balance sheets.

Net Income (Loss) per Share
12. Net Income (Loss) per Share
 
Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) 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.
 
The following presents a reconciliation of basic and diluted net income (loss) per share:

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 income (loss) per share. For the three and nine months ended December 31, 2025, there were 838,063, respectively, of potential common shares not included in the calculation of diluted net income per share because their effect was anti-dilutive. For the three months ended December 31, 2024, there were 15,526 of potential common shares not included in the calculation of diluted net income per share because their effect was anti-dilutive. For the nine months ended December 31, 2024, there were 2,516,729 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 nine months ended December 31, 2025, there were 2,775,634 and 2,711,084, respectively, of potential common shares not included in the calculation of diluted net income per share under the “if-converted” method for the Convertible Notes because their effect was anti-dilutive. For the three and nine months ended December 31, 2024 there were 2,523,304 and 2,464,622, respectively, of potential common shares not included in the calculation of diluted net income (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 December 31, 2025, the Warrants were not exercisable.

The Company recorded an income tax benefit of $434,000, or an effective tax rate of (32.3)%, and income tax expense of $1,115,000, or an effective tax rate of 32.7%, for the three months ended December 31, 2025 and 2024, respectively. The Company recorded income tax expense of $5,552,000, or an effective tax rate of 67.5%, and $1,849,000, or an effective tax rate of (10.9)%, for the nine months ended December 31, 2025 and 2024, respectively. The effective tax rate for the three and nine months ended December 31, 2025 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. and one of its Mexican 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 December 31, 2025, the Company remains subject to examination for fiscal years ended March 31, 2022 and forward. The Company believes no significant changes in the unrecognized tax benefits will occur within the next 12 months.
 
On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law in the U.S. The OBBBA included a broad range of tax reform provisions, including making permanent key elements of the Tax Cuts and Jobs Act of 2017. The OBBBA did not have a material impact to the Company for the year ended March 31, 2026 and the Company is currently evaluating the potential impact of provisions of the OBBBA that are effective in subsequent years.

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 $41,544,000 and $45,921,000 at December 31, 2025 and March 31, 2025, 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:

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 December 31, 2025 and March 31, 2025. 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 December 31, 2025, 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 December 31, 2025 and March 31, 2025, the net carrying amount of the Convertible Notes was $39,890,000 and $35,207,000, respectively (see Note 7). The estimated fair value of the Company’s Convertible Notes was $55,260,000 and $42,398,000 using Level 3 inputs at December 31, 2025 and March 31, 2025, respectively.

Performance Stock Units (“PSUs”)
 
During the nine months ended December 31, 2025, the Company granted 353,778 PSUs (at target performance levels) based on the Company’s stock price or a total shareholder return (“TSR”) market conditions. During the nine months ended December 31, 2024, the Company granted 258,983 PSUs (at target performance levels), based on a TSR market condition. All PSUs granted have a three-year performance period, subject to continued employment.
 
Stock Price PSUs
 
During the nine months ended December 31, 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 for thirty 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.
 
During the nine months ended December 31, 2024, the Company did not grant any PSUs based on the Company’s stock price.
 
TSR PSUs
 
During the nine months ended December 31, 2025 and 2024, the Company granted 176,885 and 258,983 PSUs (at target performance levels), respectively, which cliff vest and the number of shares earned at the end of the three-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 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:

Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended December 31, 2025 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2026. This report should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the fiscal year ended March 31, 2025, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on June 9, 2025.
The accompanying condensed consolidated financial statements have been prepared on a consistent basis with, and there have been no material changes to the accounting policies described in Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements that are presented in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2025.

Accounting Pronouncements Not Yet Adopted
Disclosure Improvements
In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This standard was issued in response to the SEC’s disclosure update and simplification initiative, which affects a variety of topics within the Accounting Standards Codification. The amendments apply to all reporting entities within the scope of the affected topics unless otherwise indicated. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures.
Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (Topic 740). This standard requires the Company to provide further disaggregated income tax disclosures for specific categories on the effective tax rate reconciliation, as well as additional information about federal, state/local and foreign income taxes. The standard also requires the Company to annually disclose its income taxes paid (net of refunds received), disaggregated by jurisdiction. This guidance is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is to be applied prospective basis, although optional retrospective application is permitted. The Company will adopt this standard as of March 31, 2026, and is currently evaluating the impact this guidance will have on its financial statement disclosures. The Company expects its consolidated financial statements as of March 31, 2026 to include the expanded income tax disclosures required by the standard.
Disaggregation of Income Statement Expenses
In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (“DISE”) (Subtopic 220-40). This standard requires the Company to disclose, in the footnotes at each interim and annual reporting period, information about expenses by the nature of the expense in addition to certain disclosures about selling expenses. Entities are required to include the following relevant expense captions: (i) purchase of inventory, (ii) employee compensation, (iii) depreciation, (iv) intangible asset amortization, and (v) depreciation, depletion and amortization recognized as part of oil and gas producing activities. In January 2025, the FASB issued ASU No. 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) Clarifying the Effective Date, which is intended to clarify the effective date of ASU No. 2024-03. As clarified in ASU 2025-01, the new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures.
Debt with Conversion and Other Options
In November 2024, the FASB issued ASU 2024-04, Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, which seeks to clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. This guidance is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures.
Measurement of Credit Losses
In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides a practical expedient that all entities can use when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under ASC 606, Revenue from Contracts with Customers. Under this practical expedient, an entity is allowed to assume that the current conditions it has applied in determining credit loss allowances for current accounts receivable and current contract assets remain unchanged for the remaining life of those assets. This guidance is effective for annual periods beginning after December 15, 2025, including interim reporting periods within those fiscal years, with early adoption permitted. Entities that elect the practical expedient and, if applicable, make the accounting policy election are required to apply the amendments prospectively. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and disclosures.
Internal-Use Software
In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which amends the recognition and disclosure guidance for internal-use software costs, removing the previous software development stage model with a probable-to-complete recognition threshold. This guidance is effective for annual periods beginning after December 15, 2027, including interim reporting periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and disclosures.
Interim Reporting
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270) Narrow-Scope Improvements, which improves the navigability of the guidance in ASC 270, Interim Reporting, and clarifies when it applies. Under this guidance, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. This guidance is effective for annual periods beginning after December 15, 2027, including interim reporting periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and disclosures.
Codification Improvements
In December 2025, the FASB issued ASU 2025-12, Codification Improvements, which addresses suggestions received from stakeholders regarding the Accounting Standards Codification and makes other incremental improvements to GAAP. The update represents changes to the Accounting Standards Codification that clarify, correct errors in or make other improvements to a variety of topics that are intended to make it easier to understand and apply. This guidance is effective for annual periods beginning after December 15, 2026, including interim reporting periods within those fiscal years, with early adoption permitted. Entities are required to apply the amendments to ASC 260 retrospectively. All other amendments may be applied prospectively or retrospectively. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and disclosures.
