GLOSSARY

The following terms are frequently used in the text of this report and have the meanings indicated below.

“Used Core” — An automobile part which has previously been used in the operation of a vehicle. Generally, the Used Core is an original equipment (“OE”) automobile part installed by the vehicle manufacturer and subsequently removed for replacement. Used Cores contain salvageable parts, which are an important raw material in the remanufacturing process. We obtain most Used Cores by providing credits to our customers for Used Cores returned to us under our core exchange programs. Our customers receive these Used Cores from consumers who deliver a Used Core to obtain credit from our customers upon the purchase of a newly remanufactured automobile part. When sufficient Used Cores are not available from our customers, we purchase Used Cores from core brokers, who are in the business of buying and selling Used Cores. The Used Cores purchased from core brokers or returned to us by our customers under the core exchange programs, and which have been physically received by us, are part of our raw material and work-in-process inventory. Used Cores returned by consumers to our customers but not yet returned to us are classified as contract assets until we physically receive these Used Cores.

“Remanufactured Core” — The Used Core underlying an automobile part that has gone through the remanufacturing process and through that process has become part of a newly remanufactured automobile part. The remanufacturing process takes a Used Core, breaks it down into its component parts, replaces those components that cannot be reused and reassembles the salvageable components of the Used Core and additional new components into a remanufactured automobile part. Remanufactured Cores held for sale at our customer locations are included in long-term contract assets. The Remanufactured Core portion of stock adjustment returns are classified as contract assets until we physically receive them.

Recently Adopted Accounting Pronouncements

Supplier Finance Programs

In September 2022, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50) Disclosure of Supplier Finance Program Obligations. This standard requires qualitative and quantitative disclosures to enable users of the financial statements to understand the nature, activity during the period, changes from period to period and potential magnitude of supplier finance programs. The guidance is effective for fiscal years beginning after December 15, 2022.

Table of Contents

During the three months ended December 31, 2023, the Company launched a supplier finance program as part of its ongoing efforts to improve cash flow and liquidity. This program allows certain of the Company’s suppliers to sell their receivables due from the Company to a participating financial institution at the sole discretion of both the supplier and the financial institution. The program is administered by a third party. 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. Any amounts confirmed as outstanding supplier invoices are included within accounts payable on the condensed consolidated balance sheets. As of December 31, 2023, the Company had no outstanding supplier obligations confirmed under this program.

Disclosure Improvements

In October 2023, the FASB issued 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.

Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures (Topic 280). This standard requires the Company to disclose significant segment expenses that are regularly provided to the CODM and are included within each reported measure of segment operating results. The standard also requires the Company to disclose the total amount of any other items included in segment operating results, which were not deemed to be significant expenses for separate disclosure, along with a qualitative description of the composition of these other items. In addition, the standard also requires disclosure of the CODM’s title and position, as well as detail on how the CODM uses the reported measure of segment operating results to evaluate segment performance and allocate resources. The standard also aligns interim segment reporting disclosure requirements with annual segment reporting disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its financial statement disclosures.

7. Debt

The Company is party to a $268,620,000 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”). Prior to the eighth amendment discussed below, the loans under the Credit Facility were scheduled to mature on May 28, 2026. The lenders have a security interest in substantially all of the assets of the Company.

Table of Contents

On August 3, 2023, the Company entered into a seventh amendment to the Credit Facility, which among other things, (i) permitted the Company to repay its outstanding balance of Term Loans, (ii) permitted the exclusion of quarterly principal payments of Term Loans from the fixed charge coverage ratio (including retrospectively for the prior periods) for all quarters beginning June 30, 2023, (iii) reset the fixed charge coverage ratio financial covenant level for the quarters ending September 30, 2023 and December 31, 2023, (iv) eliminated the senior leverage ratio financial covenant effective with the quarter ended June 30, 2023, (v) extended the minimum undrawn availability financial covenant through the delivery of the June 30, 2024 compliance certificate, and (vi) excluded the amount of all amendment fees and expenses incurred in connection with this amendment as well as prior unamortized fees associated with the Term Loans from bank EBITDA and the fixed charge coverage ratio financial covenant.

On August 3, 2023, the Company repaid the remaining outstanding balance of its Term Loans and recorded a loss on extinguishment of debt for the remaining unamortized debt issuance costs of $168,000 in the condensed consolidated statement of operations.

On December 12, 2023, the Company entered into an eighth amendment to the Credit Facility, which among other things, (i) extended the maturity date to December 12, 2028 from May 28, 2026, (ii) amended the definition of “Applicable Margin” to provide for a pricing grid, with the Applicable Margin for Term SOFR loans ranging from 2.75% to 3.25% and the Applicable Margin for base rate loans ranging from 1.75% to 2.25%, in each case based on average daily undrawn availability for the most recently completed calendar quarter, (iii) amended the existing fixed charge coverage ratio financial covenant that is only tested if undrawn availability (which may include up to $8,000,000 of suppressed availability) is less than 22.5% of the aggregate revolving commitments, and (iv) amended the definitions of Consolidated EBITDA and fixed charge coverage ratio and certain component definitions used therein.

The Company had $115,000,000 and $145,200,000 outstanding under the Revolving Facility at December 31, 2023 and March 31, 2023, respectively. In addition, $6,370,000 was outstanding for letters of credit at December 31, 2023. At December 31, 2023, after certain contractual adjustments, $114,168,000 was available under the Revolving Facility. The interest rate on the Company’s Revolving Facility was 8.71% and 8.13% respectively, at December 31, 2023 and March 31, 2023, respectively.

The Credit Facility, as amended, requires the Company to maintain a minimum fixed charge coverage ratio if undrawn availability is less than 22.5% of aggregate revolving commitments and a specified minimum undrawn availability. At December 31, 2023, undrawn availability was greater than the 22.5% threshold, therefore, the fixed charge coverage ratio financial covenant was not required to be tested. The Company was in compliance with these covenants as of December 31, 2023.

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. The Convertible Notes have an initial conversion price of approximately $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.

Table of Contents

On June 8, 2023, the Company entered into the first amendment to the Note Purchase Agreement, which among other things, removed a provision that specified the Purchasers would be entitled to receive a dividend or distribution payable in certain circumstances. This amendment was effective as of March 31, 2023.

On August 1, 2023, the Company entered into the second amendment to the Note Purchase Agreement, which amended the definition of “Permitted Restricted Payments” to permit the prepayment of the Company’s Term Loans.

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

	December 31, 2023			March 31, 2023

Principal amount of Convertible Notes	$	32,000,000		$	32,000,000
Less: unamortized debt discount attributed to Compound Net Derivative Liability		(7,804,000	)		(8,430,000	)
Less: unamortized debt discount attributed to debt issuance costs		(1,090,000	)		(1,006,000	)
Carrying amount of the Convertible Notes		23,106,000			22,564,000

Net carrying amount of Convertible Notes, related party	$	33,226,000		$	30,994,000

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, 2023 and March 31, 2023.

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, 2023 and March 31, 2023. 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 $13,500,000 and $10,400,000, and an asset of $3,380,000 and $1,970,000 at December 31, 2023 and March 31, 2023, respectively. During the three and nine months ended December 31, 2023, the Company recorded $1,160,000 and $1,690,000, respectively, as the change in fair value of the Compound Net Derivative Liability in the condensed consolidated statement of operations and condensed consolidated statement 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, 2023 and March 31, 2023.

Interest expense related to the Convertible Notes is as follows:

	Three Months Ended		Nine Months Ended
	December 31,		December 31,
	2023		2023

Amortization of debt issuance costs		30,000		87,000
Total interest expense	$	1,047,000	$	3,113,000

Table of Contents

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.

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.

Diluted net (loss) income per share	$	(2.40	)	$	0.05	$	(2.58	)	$	(0.29	)

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. For the three and nine months ended December 31, 2023 there were 2,130,615, respectively, of potential common shares not included in the calculation of diluted net (loss) income per share because their effect was anti-dilutive. For the three and nine months ended December 31, 2022 there were 1,201,984 and 1,897,876, respectively, of potential common shares not included in the calculation of diluted net (loss) income per share because their effect was anti-dilutive.

Table of Contents

For the three and nine months ended December 31, 2023 there were 2,293,926, respectively, of potential common shares not included in the calculation of diluted (loss) income 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, 2023, the Warrants were not exercisable.

12. Income Taxes

The Company recorded an income tax expense of $37,281,000, or an effective tax rate of (375.3%), and an income tax benefit of $8,971,000, or an effective tax rate of 112.9%, for the three months ended December 31, 2023 and 2022, respectively. The Company recorded an income tax expense of $37,226,000, or an effective tax rate of (278.7%), and an income tax benefit of $9,296,000, or an effective tax rate of 62.1%, for the nine months ended December 31, 2023 and 2022, respectively. The effective tax rate for the three and nine months ended December 31, 2023, was primarily impacted by (i) the establishment of a valuation allowance on deferred tax assets that the Company does not expect to be realized, (ii) foreign income taxed at rates that are different from the federal statutory rate, (iii) the portion of book expense related to convertible notes and derivatives that is not expected to be deductible for tax, and (iv) non-deductible executive compensation under Internal Revenue Code Section 162(m).

Management assesses the need for the valuation allowance on a quarterly basis by jurisdiction. 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. During the three months ended December 31, 2023, the Company recorded a discrete non-cash valuation allowance of $37,461,000 on U.S. federal and various state deferred tax assets that is considered not more likely than not to be realized under U.S. GAAP. This change in realizability assessment is primarily due to recent losses and an updated forecast during the three months ended December 31, 2023.

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, 2023, the Company is only under examination by the State of California for fiscal years 2020, 2021, and 2022 and remains subject to examination from the years ended March 31, 2019 and forward. The Company believes no significant changes in the unrecognized tax benefits will occur within the next 12 months.

13. 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.

Table of Contents

The Company had forward foreign currency exchange contracts with a U.S. dollar equivalent notional value of $53,301,000 and $48,486,000 at December 31, 2023 and March 31, 2023, 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:

	Gain (Loss) Recognized as Foreign Exchange Impact of Lease Liabilities and Forward Contracts
	Three Months Ended				Nine Months Ended
Derivatives Not Designated as	December 31,				December 31,
Hedging Instruments	2023		2022		2023			2022
Forward foreign currency exchange contracts	$	541,000	$	1,184,000	$	(1,771,000	)	$	445,000

The fair value of the forward foreign currency exchange contracts of $2,118,000 and $3,889,000 is included in prepaid expenses and other current assets in the condensed consolidated balance sheets at December 31, 2023 and March 31, 2023, respectively. 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 nine months ended December 31, 2023 and 2022.

14. Fair Value Measurements

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 13).

Table of Contents

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, 2023 and March 31, 2023. 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.

The following assumptions were used to determine the fair value of the Compound Net Derivative Liability:

	December 31, 2023			March 31, 2023
Risk free interest rate		4.02	%		3.64	%
Cost of equity		23.10	%		21.80	%
Weighted average cost of capital		15.50	%		14.60	%
Expected volatility of MPA common stock		50.00	%		50.00	%
EBITDA volatility		40.00	%		35.00	%

The following summarizes the activity for Level 3 fair value measurements:

	Three Months Ended		Nine Months Ended
	December 31,		December 31,
	2023		2023
Beginning balance	$	8,960,000	$	8,430,000
Changes in fair value of Compound Net Derivative Liability included in earnings		1,160,000		1,690,000
Ending balance	$	10,120,000	$	10,120,000

During the three and nine months ended December 31, 2023, 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, 2023 and March 31, 2023, the net carrying amount of the Convertible Notes was $33,226,000 and $30,994,000, respectively, with unamortized debt discounts and debt issuance costs of $8,894,000 and $9,436,000, respectively, and Compound Net Derivative Liability of $10,120,000 and $8,430,000, respectively. The estimated fair value of the Company’s Convertible Notes was $39,226,000 using Level 3 inputs at December 31, 2023. The net carrying amount of the Convertible Notes approximated their fair value at March 31, 2023, as they were issued on March 31, 2023.

15. Share-based Payments

Stock Options

The Company granted options to purchase 132,133 shares of common stock during the nine months ended December 31, 2023. No options to purchase shares of the Company’s common stock were granted during the nine months ended December 31, 2022. The cost associated with stock options is estimated using the Black-Scholes option-pricing model. This model requires the input of subjective assumptions including the expected volatility of the underlying stock and the expected holding period of the option. 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.

Table of Contents

The following assumptions were used to derive the weighted average fair value of the stock options granted:

	Nine Months Ended
	December 31,
	2023
Weighted average risk free interest rate		4.53	%
Weighted average expected holding period (years)		6.57
Weighted average expected volatility		51.29	%
Weighted average expected dividend yield		-
Weighted average fair value of options granted	$	3.75

The following is a summary of stock option transactions:

	Number of Shares			Weighted Average Exercise Price

Expired		(140,533	)	$	9.66
Outstanding at December 31, 2023		1,113,083		$	20.30

At December 31, 2023, options to purchase 132,133 shares of common stock were unvested at a weighted average exercise price of $9.32.

At December 31, 2023, there was $450,000 of total unrecognized compensation expense related to unvested stock option awards, which will be recognized over the weighted average remaining vesting period of approximately 2.7 years.

Restricted Stock Units and Restricted Stock Awards (collectively “RSUs”)

During the nine months ended December 31, 2023, the Company granted 100,624 of time-based vesting restricted stock units, based on the closing market price on the grant date. During the nine months ended December 31, 2022, the Company granted (i) performance-based restricted stock awards which had a threshold performance level of 33,333 shares, a target performance level of 66,667 shares, and a maximum performance level of 100,000 shares at the grant date and (ii) 229,121 of time-based vesting restricted stock units, respectively, based on the closing market price on the grant date.

The following is a summary of non-vested RSUs:

	Number of Shares			Weighted Average Grant Date Fair Value
Outstanding at March 31, 2023		429,354		$	15.07
Granted		100,624		$	7.95
Vested		(210,485	)	$	15.58
Forfeited/Cancelled		(77,626	)	$	13.25
Outstanding at December 31, 2023		241,867		$	12.25

At December 31, 2023, there was $2,002,000 of unrecognized compensation expense related to RSUs, which will be recognized over the weighted average remaining vesting period of approximately 1.1 years.

Performance Stock Units (“PSUs”)

During the nine months ended December 31, 2023, the Company granted 585,583 PSUs, which vest, subject to continued employment, as follows: (i) if the stock price is greater than or equal to $10.00 per share, then 1/3 of the grant will vest, (ii) if the stock price is greater than or equal to $15.00 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 $17.50 and $25.00 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, 2022 , the Company granted 126,028 PSUs (at target performance levels), which cliff vest after three-years, subject to continued employment. These awards are contingent and granted separately for each of the following metrics: adjusted EBITDA, net sales, and relative total shareholder return (“TSR”). Compensation cost at the grant date is recognized on a straight-line basis over the requisite service period to the extent the conditions are deemed probable. The number of shares earned at the end of the three-year period will vary, based only on actual performance, from 0% to 150% of the target number of PSUs granted. Adjusted EBITDA and net sales are considered performance conditions. The Company will reassess the probability of achieving each performance condition separately each reporting 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, over a given period of time. Compensation cost related to the TSR award will not be adjusted even if the market condition is not met. The Company calculated the fair value of the PSUs for each component individually.

The fair value of PSUs subject to performance conditions is equal to the closing stock price on the grant date. 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:

	Nine Months Ended December 31,
	2023			2022
Risk free interest rate		4.32-4.35	%		3.35	%
Expected life in years		0.2-1.8			3
Expected volatility of MPA common stock		54.2-55.1	%		51.30	%
Expected average volatility of peer companies		-	%		62.70	%
Average correlation coefficient of peer companies		-	%		27.50	%
Expected dividend yield		-			-
Grant date fair value	$	3.57-8.37		$	16.02

16. 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:

	Three Months Ended December 31,						Nine Months Ended December 31,
	2023			2022			2023			2022
Balance at beginning of period	$	16,197,000		$	18,461,000		$	19,830,000		$	20,125,000

Balance at end of period	$	16,130,000		$	17,572,000		$	16,130,000		$	17,572,000

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 and such.

17. Segment Information

Effective as of the fourth quarter of fiscal 2023, the Company revised its segment reporting as it determined that its three operating segments no longer met the criteria to be aggregated. The Company recast its prior year segment disclosures to conform to the current year’s presentation.

The Company’s three operating segments are:

•

Hard Parts, including (i) light duty rotating electric products such as alternators and starters, (ii) wheel hub products, (iii) brake-related products, including brake calipers, brake boosters, brake rotors, brake pads and brake master cylinders, and (iv) turbochargers,

•

Test Solutions and Diagnostic Equipment, including (i) applications for combustion engine vehicles, including bench top testers for alternators and starters, (ii) equipment for the pre- and post-production of electric vehicles, and (iii) software emulation of power system applications for the electrification of all forms of transportation (including automobiles, trucks, the emerging electrification of systems within the aerospace industry, and electric vehicle charging stations), and

•

Heavy Duty, including non-discretionary automotive aftermarket replacement hard parts for heavy-duty truck, industrial, marine, and agricultural applications.

The Company’s Hard Parts operating segment meets the criteria of a reportable segment while Test Solutions and Diagnostic Equipment and Heavy Duty are not material, are not required to be separately reported, and are included within the “all other” category.

18. Share Repurchases

In August 2018, the Company’s board of directors approved an increase in its share repurchase program from $20,000,000 to $37,000,000 of its common stock. During the three and nine months ended December 31, 2023, the Company did not repurchase any shares of its common stock. As of December 31, 2023, $18,745,000 has been utilized and $18,255,000 remains available to repurchase shares under the authorized share repurchase program, subject to the limit in the Company’s Credit Facility. The Company retired the 837,007 shares repurchased under this program through December 31, 2023. The Company’s share repurchase program does not obligate it to acquire any specific number of shares and shares may be repurchased in privately negotiated and/or open market transactions.

19. Related Party Transactions

Lease

In December 2022, the Company entered into an operating lease for its 35,000 square foot manufacturing, warehouse, and office facility in Ontario, Canada, with a company co-owned by a member of management. The lease, which commenced January 1, 2023, has an initial term of one year with a base rent of approximately $27,000 per month and includes options to renew for up to four years. In November 2023, the Company exercised one of these options to renew for an additional one-year period. The rent expense recorded for the related party lease was $81,000 and $243,000 for the three and nine months ended December 31, 2023.

Convertible Note and Election of Director

Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis presents factors that Motorcar Parts of America, Inc. and its subsidiaries (“our,” “we” or “us”) believe are relevant to an assessment and understanding of our consolidated financial position and results of operations. This financial and business analysis should be read in conjunction with our March 31, 2023 audited consolidated financial statements included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on June 14, 2023.

Risk Factors” of our most recent Annual Report on Form 10-K filed with the SEC on June 14, 2023, as updated by our subsequent filings with the SEC, for a description of these and other risks and uncertainties that could cause actual results to differ materially from those projected or implied by the forward-looking statements.

Management Overview

With a scalable infrastructure and abundant growth opportunities, we are focused on growing our aftermarket business in the North American marketplace and growing our leadership position in the test solutions and diagnostic equipment market by providing innovative and intuitive solutions to our customers. Our investments in infrastructure and human resources during the past few years reflects the significant expansion of manufacturing capacity to support multiple product lines. These investments included (i) a 410,000 square foot distribution center, (ii) two buildings totaling 372,000 square feet for remanufacturing and core sorting of brake calipers, and (iii) the realignment of production at our original 312,000 square foot facility in Mexico.

Segment Reporting

Effective as of the fourth quarter of fiscal 2023, we revised our segment reporting as we determined that our three operating segments no longer met the criteria to be aggregated. We recast our prior year segment disclosures to conform to the current year’s presentation.

Our three operating segments are as follows:

•

Heavy Duty, including non-discretionary automotive aftermarket replacement hard parts for heavy-duty truck, industrial, marine, and agricultural applications.

Table of Contents

Our Hard Parts operating segment meets the criteria of a reportable segment. The Test Solutions and Diagnostic Equipment and Heavy Duty segments are not material, are not required to be separately reported, and are included within the “all other” category. See Note 17 of the notes to condensed consolidated financial statements for more information.

Results of Operations for the Three Months Ended December 31, 2023 and 2022

The following discussion and analysis should be read together with the financial statements and notes thereto appearing elsewhere herein.

The following summarizes certain key consolidated operating data:

	Three Months Ended
	December 31,
	2023		2022
Cash flow provided by (used in) operations	$	53,615,000	$	(4,474,000	)
Finished goods turnover (annualized) (1)		3.6		3.1

(1)

Annualized finished goods turnover for the fiscal quarter is calculated by multiplying cost of goods sold for the quarter by 4 and dividing the result by the average between beginning and ending non-core finished goods inventory values for the fiscal quarter. We believe this provides a useful measure of our ability to turn our inventory into revenues.

Net Sales and Gross Profit

The following summarizes net sales and gross profit:

	Three Months Ended
	December 31,
	2023			2022
Net sales	$	171,862,000		$	151,819,000
Cost of goods sold		141,819,000			130,826,000
Gross profit		30,043,000			20,993,000
Gross profit percentage		17.5	%		13.8	%

Net Sales. Our consolidated net sales for the three months ended December 31, 2023 were $171,862,000, which represents an increase of $20,043,000, or 13.2%, from the three months ended December 31, 2022 of $151,819,000. Our sales for the three months ended December 31, 2023 compared with the three months ended December 31, 2022 reflect strong demand across all product lines.

Gross Profit. Our consolidated gross profit was $30,043,000, or 17.5% of consolidated net sales, for the three months ended December 31, 2023 compared with $20,993,000, or 13.8% of consolidated net sales, for the three months ended December 31, 2022. The increase in our gross margin for the three months ended December 31, 2023 reflects increased utilization of our facilities and the benefit of price increases that went into effect during prior periods.

In addition, our gross margin for the three months ended December 31, 2023 compared with the three months ended December 31, 2022 was impacted by (i) additional expenses of $1,555,000 and $2,370,000, respectively, primarily due to certain costs for disruptions in the supply chain, (ii) amortization of core and finished goods premiums paid to customers related to new business of $2,838,000 and $3,075,000, respectively, and (iii) the non-cash quarterly revaluation of cores that are part of the finished goods on the customers’ shelves (which are included in contract assets) to the lower of cost or net realizable value, which resulted in a write-down of $1,607,000 and $863,000, respectively.

Sales and marketing		3.5	%		3.7	%
Research and development		1.5	%		1.7	%
Foreign exchange impact of lease liabilities and forward contracts		(1.8	)%		(2.8	)%

General and Administrative. Our general and administrative expenses for the three months ended December 31, 2023 were $15,198,000, which represents an increase of $1,599,000, or 11.8%, from the three months ended December 31, 2022 of $13,599,000. This increase was primarily for employee-related expenses, which included (i) $1,777,000 of increased employee incentives and (ii) $405,000 of increased share-based compensation expense in connection with equity grants made to employees. These increases were partially offset by $596,000 of decreased severance expense due to headcount reductions during the three months ended December 31, 2022.

Sales and Marketing. Our sales and marketing expenses for the three months ended December 31, 2023 were $5,931,000, which represents an increase of $297,000, or 5.3%, from the three months ended December 31, 2022 of $5,634,000. This increase was primarily due to increased employee-related expenses and higher commissions, which resulted from higher sales, partially offset by reduced expenses for trade shows during the three months ended December 31, 2023 compared with the three months ended December 31, 2022.

Research and Development. Our research and development expenses were consistent at $2,539,000 for the three months ended December 31, 2023 compared with $2,547,000 for the three months ended December 31, 2022.

Foreign Exchange Impact of Lease Liabilities and Forward Contracts. Our foreign exchange impact of lease liabilities and forward contracts were non-cash gains of $3,149,000 and $4,313,000 for the three months ended December 31, 2023 and 2022, respectively. This change during the three months ended December 31, 2023 compared with the three months ended December 31, 2022 was primarily due to (i) the remeasurement of our foreign currency-denominated lease liabilities, which resulted in non-cash gains of $2,608,000 and $3,129,000, respectively, due to foreign currency exchange rate fluctuations and (ii) the forward foreign currency exchange contracts, which resulted in non-cash gains of $541,000 and $1,184,000, respectively, due to the changes in their fair values.

Operating Income

Consolidated Operating Income. Our consolidated operating income for the three months ended December 31, 2023 was $9,524,000, which represents an increase of $5,998,000, or 170.1%, from the three months ended December 31, 2022 of $3,526,000. This increase was primarily due to higher sales and gross profit as discussed above.

Interest Expense

Interest Expense, net. Our interest expense for the three months ended December 31, 2023 was $18,297,000, which represents an increase of $6,826,000, or 59.5%, from interest expense for the three months ended December 31, 2022 of $11,471,000. This increase was primarily due to (i) increased utilization of and higher interest rates on our accounts receivable discount programs, which have variable interest rates and (ii) non-cash interest expense incurred on the Convertible Notes issued on March 31, 2023.

Change in Fair Value of Compound Net Derivative Liability

Change in Fair Value of Compound Net Derivative Liability. Our change in fair value of compound net derivative liability for the three months ended December 31, 2023 was a non-cash loss of $1,160,000 associated with the convertible notes issued on March 31, 2023.

Loss on Extinguishment of Debt

Loss on Extinguishment of Debt. We did not incur any loss on extinguishment of debt during the three months ended December 31, 2023.

Provision for Income Taxes

Income Tax. We recorded an income tax expense of $37,281,000, or an effective tax rate of (375.3%), and an income tax benefit of $8,971,000, or an effective tax rate of 112.9%, for the three months ended December 31, 2023 and 2022, respectively. During the three months ended December 31, 2023, we recorded a discrete non-cash valuation allowance of $37,461,000 on our U.S. federal and various state deferred tax assets primarily due to recent losses. The change in the valuation allowance resulted from an updated forecast during the three months ended December 31, 2023. The effective tax rate for the three months ended December 31, 2023, was primarily impacted by (i) the establishment of a valuation allowance on deferred tax assets that we do not expect to be realized, (ii) foreign income taxed at rates that are different from the federal statutory rate, (iii) the portion of book expense related to convertible notes and derivatives that is not expected to be deductible for tax, and (iv) non-deductible executive compensation under Internal Revenue Code Section 162(m).

Results of Operations for the Nine Months Ended December 31, 2023 and 2022

The following discussion and analysis should be read together with the financial statements and notes thereto appearing elsewhere herein.

The following summarizes certain key consolidated operating data:

	Nine Months Ended
	December 31,
	2023		2022
Cash flow provided by (used in) operations	$	48,445,000	$	(21,428,000	)
Finished goods turnover (annualized) (1)		3.7		3.3

(1)

Annualized finished goods turnover for the fiscal period is calculated by multiplying cost of goods sold for the period by 1.33 and dividing the result by the average between beginning and ending non-core finished goods inventory values for the fiscal period. We believe this provides a useful measure of our ability to turn our inventory into revenues.

Liquidity and Capital Resources

Overview

We had working capital (current assets minus current liabilities) of $154,815,000 and $154,886,000, a ratio of current assets to current liabilities of 1.4:1.0, at December 31, 2023 and March 31, 2023, respectively.

Our primary source of liquidity was from cash generated from operations during the nine months ended December 31, 2023. We believe cash generated from operations, our cash and cash equivalents, use of accounts receivable discount programs, amounts available under our credit facility, and other sources are sufficient to satisfy our working capital needs, and lease and capital expenditure obligations over the next 12 months.

Share Repurchase Program

In August 2018, our board of directors approved an increase in our share repurchase program from $20,000,000 to $37,000,000 of our common stock. As of December 31, 2023, $18,745,000 had been utilized and $18,255,000 remains available to repurchase shares under the authorized share repurchase program, subject to the limit in our credit facility. We retired the 837,007 shares repurchased under this program through December 31, 2023. Our share repurchase program does not obligate us to acquire any specific number of shares and shares may be repurchased in privately negotiated and/or open market transactions.

Net cash used in investing activities was $420,000 and $3,855,000 during the nine months ended December 31, 2023 and 2022, respectively. The change in our investing activities primarily resulted from decreased capital expenditures.

Net cash used in financing activities was $47,646,000 during the nine months ended December 31, 2023 compared with net cash provided by financing activities of $14,898,000 during the nine months ended December 31, 2022.

Capital Resources

Credit Facility

We are party to a $268,620,000 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”). Prior to the eighth amendment discussed below, the loans under the Credit Facility were scheduled to mature on May 28, 2026. The lenders have a security interest in substantially all of our assets.

On August 3, 2023, we entered into a seventh amendment to the Credit Facility, which among other things, (i) permitted us to repay our outstanding balance of Term Loans, (ii) permitted the exclusion of quarterly principal payments of Term Loans from the fixed charge coverage ratio (including retrospectively for the prior periods) for all quarters beginning June 30, 2023, (iii) reset the fixed charge coverage ratio financial covenant level for the quarters ending September 30, 2023 and December 31, 2023, (iv) eliminated the senior leverage ratio financial covenant effective with the quarter ended June 30, 2023, (v) extended the minimum undrawn availability financial covenant through the delivery of the June 30, 2024 compliance certificate, and (vi) excluded the amount of all amendment fees and expenses incurred in connection with this amendment as well as prior unamortized fees associated with the Term Loans from bank EBITDA and the fixed charge coverage ratio financial covenant.

On August 3, 2023, we repaid the remaining outstanding balance of our Term Loans and recorded a loss on extinguishment of debt for the remaining unamortized debt issuance costs of $168,000 in the condensed consolidated statement of operations.

On December 12, 2023, we entered into an eighth amendment to the Credit Facility, which among other things, (i) extended the maturity date to December 12, 2028 from May 28, 2026, (ii) amended the definition of “Applicable Margin” to provide for a pricing grid, with the Applicable Margin for Term SOFR loans ranging from 2.75% to 3.25% and the Applicable Margin for base rate loans ranging from 1.75% to 2.25%, in each case based on average daily undrawn availability for the most recently completed calendar quarter, (iii) amended the existing fixed charge coverage ratio financial covenant that is only tested if undrawn availability (which may include up to $8,000,000 of suppressed availability) is less than 22.5% of the aggregate revolving commitments, and (iv) amended the definitions of Consolidated EBITDA and fixed charge coverage ratio and certain component definitions used therein.

We had $115,000,000 and $145,200,000 outstanding under the Revolving Facility at December 31, 2023 and March 31, 2023, respectively. In addition, $6,370,000 was outstanding for letters of credit at December 31, 2023. At December 31, 2023, after certain contractual adjustments, $114,168,000 was available under the Revolving Facility. The interest rate on our Revolving Facility was 8.71% and 8.13% respectively, at December 31, 2023 and March 31, 2023, respectively.

The Credit Facility, as amended, requires us 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. At December 31, 2023, the undrawn availability was greater than the 22.5% threshold, therefore, the fixed charge coverage ratio financial covenant was not required to be tested. We were in compliance with these covenants as of December 31, 2023.

Convertible Notes

On March 31, 2023, we 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. The Convertible Notes have an initial conversion price of approximately $15.00 per share of common stock. (“Conversion Option”). Unless and until we deliver 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 our common stock. Except in the case of the occurrence of a fundamental transaction, as defined in the form of convertible promissory note, we may not redeem the Convertible Notes prior to March 31, 2026. After March 31, 2026, we may redeem all or part of the Convertible Notes for a cash purchase (the “Company Redemption”) price.

On June 8, 2023, we entered into the first amendment to the Note Purchase Agreement, which among other things, removed a provision that specified the Purchasers would be entitled to receive a dividend or distribution payable in certain circumstances. This amendment was effective as of March 31, 2023.

On August 1, 2023, we entered into the second amendment to the Note Purchase Agreement, which amended the definition of “Permitted Restricted Payments” to permit the prepayment of our Term Loans.

In connection with the Note Purchase Agreement, we 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, 2023 and March 31, 2023.

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, 2023 and March 31, 2023. 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 $13,500,000 and $10,400,000, and an asset of $3,380,000 and $1,970,000 at December 31, 2023 and March 31, 2023, respectively. During the three and nine months ended December 31, 2023, we recorded $1,160,000 and $1,690,000, respectively, as the change in fair value of the Compound Net Derivative Liability in the condensed consolidated statement of operations and condensed consolidated statement of cash flows.

Accounts Receivable Discount Programs

We use accounts receivable discount programs offered by certain customers and their respective banks. Under these programs, we have options to 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 us to accelerate receipt of payment on customers’ receivables. While these arrangements have reduced our working capital needs, there can be no assurance that these programs will continue in the future. Interest expense resulting from these programs would increase if interest rates rise, if utilization of these discounting arrangements expands, if customers extend their payment to us, or if the discount period is extended to reflect more favorable payment terms to customers.

Table of Contents

The following is a summary of the accounts receivable discount programs:

	Nine Months Ended December 31,
	2023			2022
Receivables discounted	$	465,073,000		$	428,868,000
Weighted average number of days collection was accelerated		334			323
Annualized weighted average discount rate		6.8	%		5.0	%
Amount of discount recognized as interest expense	$	29,395,000		$	19,131,000

Capital Expenditures and Commitments

Capital Expenditures

Our total capital expenditures, including finance leases and non-cash capital expenditures were $559,000 and $3,632,000 for the nine months ended December 31, 2023 and 2022, respectively. These capital expenditures primarily include the purchase of equipment for our operations. We expect to incur approximately $1,500,000 of capital expenditures during fiscal 2024 to support our operations. We have used and expect to continue using our working capital and additional capital lease obligations to finance these capital expenditures.

Related Party Transactions

Lease

In December 2022, we entered into an operating lease for our 35,000 square foot manufacturing, warehouse, and office facility in Ontario, Canada, with a company co-owned by a member of management. The lease, which commenced January 1, 2023, had an initial term of one year with a base rent of approximately $27,000 per month and included options to renew for up to four years. In November 2023, we exercised one of these options to renew for an additional one-year period. The rent expense recorded for the related party lease was $81,000 and $243,000 for the three and nine months ended December 31, 2023.

Convertible Note and Election of Director

In connection with the issuance and sale of our Convertible Notes on March 31, 2023, the Board appointed Douglas Trussler, a co-founder of Bison Capital in 2001, to the Board. Mr. Trussler’s compensation will be consistent with our previously disclosed standard compensation practices for non-employee directors, which are described in our Definitive Proxy Statement, filed with the SEC on July 28, 2023.

Litigation

We are 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 our business, and our compliance with law, code, and regulations related to all matters including but not limited to environmental, information security, taxes, levies, tariffs and such.

Critical Accounting Policies

There have been no material changes to, except as noted below, our critical accounting policies and estimates that are presented in our Annual Report on Form 10-K for the year ended March 31, 2023, which was filed on June 14, 2023.

Recently Adopted Accounting Pronouncements

Supplier Finance Programs

In September 2022, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50) Disclosure of Supplier Finance Program Obligations. This standard requires qualitative and quantitative disclosures sufficient to enable users of the financial statements to understand the nature, activity during the period, changes from period to period and potential magnitude of supplier finance programs. The guidance is effective for fiscal years beginning after December 15, 2022.

During the three months ended December 31, 2023, we launched a supplier finance program as part of our ongoing efforts to improve cash flow and liquidity. This program allows certain of our suppliers to sell their receivables due from us to a participating financial institution at the sole discretion of both the supplier and the financial institution. The program is administered by a third party. We have 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 on related to the volume or number of financing agreements between suppliers, financial institution, and the third-party administrator. We are not a party to agreements negotiated between participating suppliers and the financial institution. Our obligations to our suppliers, including amounts due and payment terms, are not affected by a supplier's decision to participate in this program. We do 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. Any amounts confirmed as outstanding supplier invoices are included within accounts payable on the condensed consolidated balance sheets. As of December 31, 2023, we had no outstanding supplier obligations confirmed under this program.

Accounting Pronouncements Not Yet Adopted

Disclosure Improvements

In October 2023, the FASB issued 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. We are currently evaluating the impact this guidance will have on our financial statement disclosures.

Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures (Topic 280). This standard requires us to disclose significant segment expenses that are regularly provided to the CODM and are included within each reported measure of segment operating results. The standard also requires us to disclose the total amount of any other items included in segment operating results, which were not deemed to be significant expenses for separate disclosure, along with a qualitative description of the composition of these other items. In addition, the standard also requires disclosure of the CODM’s title and position, as well as detail on how the CODM uses the reported measure of segment operating results to evaluate segment performance and allocate resources. The standard also aligns interim segment reporting disclosure requirements with annual segment reporting disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. We are currently evaluating the impact this guidance will have on our financial statement disclosures.

Table of Contents

Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (Topic 740). This standard requires us 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 us to annually disclose our 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. We are currently evaluating the impact this guidance will have on our financial statement disclosures.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes in market risk from the information provided in Item 7A. “Quantitative and Qualitative Disclosures About Market Risk” in our Annual Report on Form 10-K as of March 31, 2023, which was filed with the SEC on June 14, 2023.

Item 4.

Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures designed to ensure that the information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that such information is accumulated and communicated to management, including our chief executive officer, chief financial officer, and chief accounting officer, as appropriate to allow timely decisions regarding required disclosures.

Under the supervision and with the participation of management, including our chief executive officer, chief financial officer, and chief accounting officer, we have conducted an evaluation of the effectiveness of our disclosure controls and procedures as defined in Exchange Act Rules 13a-15(e) and 15d-15(e). Based on this evaluation, our chief executive officer, chief financial officer, and chief accounting officer concluded that MPA’s disclosure controls and procedures were effective as of December 31, 2023.

Inherent Limitations on Effectiveness of Controls

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rules 13a-15(f) and 15d-15(f).

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America, applying certain estimates and judgments as required.

Internal control over financial reporting includes those policies and procedures that:

1. Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

2. Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

3. Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Table of Contents

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) that occurred during the three months ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Basis of Presentation and New Accounting Pronouncements	2. Basis of Presentation and New Accounting Pronouncements 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, 2023 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2024. 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, 2023, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on June 14, 2023. The accompanying condensed consolidated financial statements have been prepared on a consistent basis with, and there have been no material changes to, except as noted below, 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, 2023. Recently Adopted Accounting Pronouncements Supplier Finance Programs In September 2022, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50) Disclosure of Supplier Finance Program Obligations. This standard requires qualitative and quantitative disclosures to enable users of the financial statements to understand the nature, activity during the period, changes from period to period and potential magnitude of supplier finance programs. The guidance is effective for fiscal years beginning after December 15, 2022. During the three months ended December 31, 2023, the Company launched a supplier finance program as part of its ongoing efforts to improve cash flow and liquidity. This program allows certain of the Company’s suppliers to sell their receivables due from the Company to a participating financial institution at the sole discretion of both the supplier and the financial institution. The program is administered by a third party. 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. Any amounts confirmed as outstanding supplier invoices are included within accounts payable on the condensed consolidated balance sheets. As of December 31, 2023, the Company had no outstanding supplier obligations confirmed under this program. Accounting Pronouncements Not Yet Adopted Disclosure Improvements In October 2023, the FASB issued 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. Reportable Segment Disclosures In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures (Topic 280). This standard requires the Company to disclose significant segment expenses that are regularly provided to the CODM and are included within each reported measure of segment operating results. The standard also requires the Company to disclose the total amount of any other items included in segment operating results, which were not deemed to be significant expenses for separate disclosure, along with a qualitative description of the composition of these other items. In addition, the standard also requires disclosure of the CODM’s title and position, as well as detail on how the CODM uses the reported measure of segment operating results to evaluate segment performance and allocate resources. The standard also aligns interim segment reporting disclosure requirements with annual segment reporting disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. 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 is currently evaluating the impact this guidance will have on its financial statement disclosures.

Income Taxes [Abstract]
Income Taxes	12. Income Taxes The Company recorded an income tax expense of $37,281,000, or an effective tax rate of (375.3%), and an income tax benefit of $8,971,000, or an effective tax rate of 112.9%, for the three months ended December 31, 2023 and 2022, respectively. The Company recorded an income tax expense of $37,226,000, or an effective tax rate of (278.7%), and an income tax benefit of $9,296,000, or an effective tax rate of 62.1%, for the nine months ended December 31, 2023 and 2022, respectively. The effective tax rate for the three and nine months ended December 31, 2023, was primarily impacted by (i) the establishment of a valuation allowance on deferred tax assets that the Company does not expect to be realized, (ii) foreign income taxed at rates that are different from the federal statutory rate, (iii) the portion of book expense related to convertible notes and derivatives that is not expected to be deductible for tax, and (iv) non-deductible executive compensation under Internal Revenue Code Section 162(m). Management assesses the need for the valuation allowance on a quarterly basis by jurisdiction. 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. During the three months ended December 31, 2023, the Company recorded a discrete non-cash valuation allowance of $37,461,000 on U.S. federal and various state deferred tax assets that is considered not more likely than not to be realized under U.S. GAAP. This change in realizability assessment is primarily due to recent losses and an updated forecast during the three months ended December 31, 2023. 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, 2023, the Company is only under examination by the State of California for fiscal years 2020, 2021, and 2022 and remains subject to examination from the years ended March 31, 2019 and forward. The Company believes no significant changes in the unrecognized tax benefits will occur within the next 12 months.

Basis of Presentation and New Accounting Pronouncements [Abstract]
Basis of Presentation	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, 2023 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2024. 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, 2023, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on June 14, 2023. The accompanying condensed consolidated financial statements have been prepared on a consistent basis with, and there have been no material changes to, except as noted below, 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, 2023.
Recently Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements Supplier Finance Programs In September 2022, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50) Disclosure of Supplier Finance Program Obligations. This standard requires qualitative and quantitative disclosures to enable users of the financial statements to understand the nature, activity during the period, changes from period to period and potential magnitude of supplier finance programs. The guidance is effective for fiscal years beginning after December 15, 2022. During the three months ended December 31, 2023, the Company launched a supplier finance program as part of its ongoing efforts to improve cash flow and liquidity. This program allows certain of the Company’s suppliers to sell their receivables due from the Company to a participating financial institution at the sole discretion of both the supplier and the financial institution. The program is administered by a third party. 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. Any amounts confirmed as outstanding supplier invoices are included within accounts payable on the condensed consolidated balance sheets. As of December 31, 2023, the Company had no outstanding supplier obligations confirmed under this program. Accounting Pronouncements Not Yet Adopted Disclosure Improvements In October 2023, the FASB issued 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. Reportable Segment Disclosures In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures (Topic 280). This standard requires the Company to disclose significant segment expenses that are regularly provided to the CODM and are included within each reported measure of segment operating results. The standard also requires the Company to disclose the total amount of any other items included in segment operating results, which were not deemed to be significant expenses for separate disclosure, along with a qualitative description of the composition of these other items. In addition, the standard also requires disclosure of the CODM’s title and position, as well as detail on how the CODM uses the reported measure of segment operating results to evaluate segment performance and allocate resources. The standard also aligns interim segment reporting disclosure requirements with annual segment reporting disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. 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 is currently evaluating the impact this guidance will have on its financial statement disclosures.
