 Notes to Consolidated Financial Statements

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 To the stockholders and the Board of Directors of Graham Corporation
 Opinion on the Financial Statements
 We have audited the accompanying consolidated balance sheets of Graham Corporation and subsidiaries (the "Company") as of March 31, 2024 and 2023; the related consolidated statements of operations, comprehensive (loss) income, changes in stockholders' equity, and cash flows, for each of the three years in the period ended March 31, 2024 and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of March 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended March 31, 2024, in conformity with accounting principles generally accepted in the United States of America.
 We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of March 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated June 7, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.
 Basis for Opinion
 These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
 Critical Audit Matter
 The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
 Revenue Recognition — Over time Revenue – Refer to Notes 1 and 3 to the financial statements
 Critical Audit Matter Description

 The Company recognizes a majority of its revenue over time when contract performance results in the creation of a product for which the Company does not have an alternative use and the contract includes an enforceable right to payment in an amount that corresponds directly with the value of the performance completed. To measure progress towards completion on performance obligations for which revenue is recognized over time the Company primarily utilizes an input method based upon a ratio of direct labor hours incurred to date to management's estimate of the total direct labor hours to be incurred at completion on each contract or an input method based upon a ratio of direct costs incurred to date to management's estimate of total costs to be incurred at the completion of each contract. Revenue from contracts that is recognized over time accounted for approximately 77% of revenue in fiscal 2024.

 We identified revenue associated with certain in-process
 contracts recognized over time utilizing an input method as a critical audit matter because of the judgments necessary for management to estimate total direct labor hours or costs, at completion. An extensive audit effort and a high degree of auditor judgment was required when performing audit procedures to audit management's estimates of total direct labor hours or total costs at completion used to recognize revenue over time and evaluating the results of those procedures.
 How the Critical Audit Matter Was Addressed in the Audit

 Our audit procedures related to management's estimate of total direct labor hours or total costs, at completion, for in-process
 contracts recognized over time included the following, among others:

 •

 We tested the effectiveness of controls over management's estimate of total direct labor hours or total costs at completion for in-process
 contracts recognized over time.

 •

 Performed a risk assessment over the contract population which included analyzing the population using various characteristics of audit interest

 •

 We tested the mathematical accuracy of management's calculation of revenue recognized over time.

 •

 For a selection of in-process
 contracts with customers that were recognized over time utilizing an input method, we performed the following procedures, among others:

 a.

 Evaluated whether the contracts were properly included in management's calculation of revenue recognized over time based on the terms and conditions of each contract.

 b.

 Evaluated the reasonableness and consistency of the methodology used by management to estimate total direct labor hours or total costs at completion for each contract and tested the mathematical accuracy of such estimate.

 c.

 Evaluated the direct labor hours or costs estimate by obtaining original estimates and any change orders, testing direct labor hours or costs completed to date, observing the work sites and inspecting the progress to completion as of fiscal year end, and performing corroborating inquiries with the Company's project managers and engineers regarding the estimates of total direct labor hours or total costs at completion.

 •

 We evaluated management's ability to estimate total direct labor hours or total costs at completion accurately by comparing actual direct labor hours or costs incurred to management's historical estimates for a selection of similar contracts that were completed in fiscal year 2024.

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 Years Ended March 31, 2024, 2023 and 2022
 (Amounts in thousands, except per share data)
 Note 1 - The Company and Its Accounting Policies:
 Graham Corporation, and its operating subsidiaries, (together, the "Company"), is a global leader in the design and manufacture of mission critical fluid, power, heat transfer and vacuum technologies for the defense, space, energy and process industries. The Company acquired Barber-Nichols, LLC ("BN") in June 2021. The accompanying Consolidated Financial Statements include BN at March 31, 2024, 2023 and for the period June 1, 2021 through March 31, 2024. The Company acquired P3 Technologies, LLC ("P3") in November 2023. The accompanying Consolidated Financial Statements include P3 at March 31, 2024 and for the period of November 9, 2023 through March 31, 2024. The Company's significant accounting policies are set forth below.
 The Company's fiscal years ended March 31, 2024, 2023 and 2022 are referred to as "fiscal 2024," "fiscal 2023" and "fiscal 2022," respectively.
 Principles of consolidation and use of estimates in the preparation of consolidated financial statements

 The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, BN, located in Arvada, CO, P3, located in Jupiter, FL, Graham Vacuum and Heat Transfer Technology (Suzhou) Co., Ltd., located in China, and Graham India Private Limited ("GIPL"), located in India. All intercompany balances, transactions and profits are eliminated in consolidation.
 The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the related revenues and expenses during the reporting period. Actual amounts could differ from those estimated.
 Translation of foreign currencies

 Assets and liabilities of the Company's foreign subsidiaries are translated into U.S. dollars at currency exchange rates in effect at year end and revenues and expenses are translated at average exchange rates in effect for the year. Gains and losses resulting from foreign currency transactions are included in results of operations. The Company's sales and purchases in foreign currencies are not material to the overall consolidated financial statements. Therefore, foreign currency transaction gains and losses have not historically impacted the Company's financial results materially. Gains and losses resulting from translation of the foreign subsidiaries balance sheets are included in a separate component of stockholders' equity. Translation adjustments are not adjusted for income taxes since they relate to an investment, which is permanent in nature.
 Revenue recognition

 The Company accounts for revenue in accordance with Accounting Standard Codification 606, "Revenue from Contracts with Customers" ("ASC 606").
 The Company recognizes revenue on all contracts when control of the product is transferred to the customer. Control is generally transferred when products are shipped, title is transferred, significant risks of ownership have transferred, the Company has rights to payment, and rewards of ownership pass to the customer. Customer acceptance may also be a factor in determining whether control of the product has transferred. Although revenue on the majority of the Company's contracts, as measured by number of contracts, is recognized upon shipment to the customer, revenue on larger contracts, which are fewer in number but generally represent the majority of revenue, is recognized over time as these contracts meet specific criteria in ASC 606.
 Unbilled revenue (contract assets) in the Consolidated Balance Sheets represents revenue recognized that has not been billed to customers on contracts in which revenue is recognized over time. All progress payments exceeding unbilled revenue are presented as customer deposits (contract liabilities) in the Consolidated Balance Sheets.
 Cash and cash equivalents

 Cash and cash equivalents consist of cash and highly liquid, short-term investments with maturities at the time of purchase of three months or less.

 Trade Accounts receivable, net of allowances

 Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The provision for credit losses is the Company's best estimate of the amount of probable credit losses in the Company's existing accounts receivable; however, changes in circumstances relating to accounts receivable may result in a requirement for additional provisions in the future.
 Shipping and handling fees and costs

 Shipping and handling fees billed to the customer are recorded in Net sales and the related costs incurred for shipping and handling are included in Cost of products sold.

 Inventories are stated at the lower of cost or net realizable value, using the average cost method.
 Property, plant, equipment and depreciation

 Property, plant and equipment are stated at cost net of accumulated depreciation. Major additions and improvements are capitalized, while maintenance and repairs are charged to expense as incurred. Depreciation is provided based upon the estimated useful lives, or lease term if shorter, under the straight-line method. Estimated useful lives range from approximately three to eight years for office equipment, eight to 25 years for manufacturing equipment, eight years for land improvements, 40 years for buildings and improvements, and leasehold improvements are depreciated over the remaining term of the lease. Upon sale or retirement of assets, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations.
 Business combinations

 The Company records its business combinations under the acquisition method of accounting. Under the acquisition method of accounting, the Company allocates the purchase price of each acquisition to the tangible and identifiable intangible assets acquired and liabilities assumed based on their respective fair values at the date of acquisition. The fair value of identifiable intangible assets is based upon detailed valuations that use various assumptions made by management. Any excess of the purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Direct acquisition-related costs are expensed as incurred.

 Goodwill

 Goodwill represents the excess of the purchase price over the fair value of identifiable net tangible and intangible assets acquired in a business combination.
 Goodwill is not amortized, but is reviewed for impairment at least annually or more frequently if impairment indicators arise. Goodwill is evaluated for impairment by first performing a qualitative assessment to determine whether a quantitative goodwill test is necessary. If it is determined, based on qualitative factors, that the fair value of the reporting unit may be more likely than not less than its carrying amount, or if significant adverse changes in the Company's future financial performance occur that could materially impact fair value, a quantitative goodwill impairment test would be required. Additionally, the Company can elect to forgo the qualitative assessment and perform the quantitative test. If the qualitative assessment indicates that the quantitative analysis should be performed, or if management elects to bypass a qualitative assessment, the Company then evaluates goodwill for impairment by comparing the fair value of the reporting unit to its carrying amount, including goodwill.
 Intangible Assets

 Acquired intangible assets other than goodwill consist of backlog, customer relationships, technology and technical know-how
 and tradenames. Backlog and trade names are included in the line item Other intangible assets, net in the Consolidated Balance Sheet. The Company amortizes a portion of its Technology and technical know-how,
 tradenames, and Customer relationships in Selling, general and administrative expense on a straight line basis over each of their estimated useful lives of eight to twenty years. Backlog and a portion of Technology and technical know-how
 are amortized in Cost of products sold over the projected conversion period of four to ten years which is based on management estimates at the time of purchase. All other intangibles have indefinite lives and are not amortized.
 Impairment of long-lived assets

 The Company assesses the impairment of definite-lived long-lived assets or asset groups when events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that are considered in deciding when to perform an impairment review include: a significant decrease in the market price of the asset or asset group; a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction; a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; or a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The term more likely than not refers to a level of likelihood that is more than 50%.
 Recoverability potential is measured by comparing the carrying amount of the asset or asset group to its related total future undiscounted cash flows. If the carrying value is not recoverable through related cash flows, the asset or asset group is considered to be impaired. Impairment is measured by comparing the asset or asset group's carrying amount to its fair value. When it is determined that useful lives of assets are shorter than originally estimated, and no impairment is present, the rate of depreciation is accelerated in order to fully depreciate the assets over their new shorter useful lives.
 Goodwill and intangible assets with indefinite lives are tested annually for impairment. The Company assesses goodwill for impairment by comparing the fair value of its reporting units to their carrying amounts. If the fair value of a reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the implied fair value of the goodwill within the reporting unit is less than its carrying value. Fair values for reporting units are determined based on a weighted combination of the market approach and the income approach using discounted cash flows. Indefinite lived intangible assets are assessed for impairment by comparing the fair value of the asset to its carrying value.
 Other Long-Term Assets

 Other long-term assets include service based cloud computing software implementation costs of $361. Upon implementation completion, these costs will be amortized over the expected term of the hosting arrangement on a straight line basis.
 Product warranties

 The Company estimates the costs that may be incurred under its product warranties and records a liability in the amount of such costs at the time revenue is recognized. The reserve for product warranties is based upon past claims experience and ongoing evaluations of any specific probable claims from customers. A reconciliation of the changes in the product warranty liability is presented in Note 7.

 Research and development

 Research and development costs are expensed as incurred. The Company incurred estimated research and development costs of $3,944 in fiscal 2024 and research and development costs of $4,144 and $3,845 in fiscal 2023 and fiscal 2022, respectively. Research and development costs are included in the line item Cost of products sold and Selling, general and administrative in the Consolidated Statements of Operations.
 Income taxes

 The Company recognizes deferred income tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company's financial statements or tax returns. Deferred income tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using currently enacted tax rates. The Company evaluates the available evidence about future taxable income and other possible sources of realization of deferred income tax assets and records a valuation allowance to reduce deferred income tax assets to an amount that represents the Company's best estimate of the amount of such deferred income tax assets that more likely than not will be realized.
 The Company accounts for uncertain tax positions using a "more likely than not" recognition threshold. The evaluation of uncertain tax positions is based on factors including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective resolution of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. These tax positions are evaluated on a quarterly basis. It is the Company's policy to recognize any interest related to uncertain tax positions in interest expense and any penalties related to uncertain tax positions in selling, general and administrative expense.
 The Company files federal and state income tax returns in several U.S. and non-U.S.
 domestic and foreign jurisdictions. In most tax jurisdictions, returns are subject to examination by the relevant tax authorities for a number of years after the returns have been filed.
 Equity-based compensation

 The Company records compensation costs related to equity-based awards based on the estimated fair value of the award on the grant date. Compensation cost is recognized in the Company's Consolidated Statements of Operations over the applicable vesting period. The Company uses the Black-Scholes valuation model as the method for determining the fair value of its stock option awards. For service and performance based restricted stock awards and restricted stock units, the fair market value of the award is determined based upon the closing value of the Company's stock price on the grant date. The fair market value of market-based performance restricted stock awards is determined using the Monte Carlo valuation model. The amount of equity-based compensation expense recognized during a period is based on the portion of the awards that ultimately vest.

 Income (loss) per share data

 Basic income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted income (loss) per share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding and, when applicable, potential common shares outstanding during the period.
 A reconciliation of the numerators and denominators of basic and diluted income (loss) per share is presented below:

 Accumulated other comprehensive income (loss)

 Comprehensive income (loss) is comprised of net income and other comprehensive income or loss items, which are accumulated as a separate component of stockholders' equity. For the Company, other comprehensive income or loss items include foreign currency translation adjustments and pension and other postretirement benefit adjustments.
 Fair value measurements

 Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the "exit price") in an orderly transaction between market participants at the measurement date. The accounting standard for fair value establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of inputs as follows:

 Level 1 – Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment.
 Level 2 – Valuations determined from quoted prices for similar assets or liabilities in active markets, quoted prices for identical instruments in markets that are not active or by model-based techniques in which all significant inputs are observable in the market.
 Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.
 The availability of observable inputs can vary and is affected by a wide variety of factors, including, the type of asset/liability, whether the asset/liability is established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
 Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, assumptions are required to reflect those that market participants would use in pricing the asset or liability at the measurement date.
 Use of Estimates

 The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of sales and expenses during the reporting period. Actual results could differ materially from those estimates.
 Accounting and reporting changes

 In the normal course of business, management evaluates all new Accounting Standards Updates and other accounting pronouncements issued by the Financial Accounting Standards Board, Securities and Exchange Commission, or other authoritative accounting bodies to determine the potential impact they may have on the Company's Consolidated Financial Statements. Other than those discussed below, management does not expect any of the recently issued accounting pronouncements, which have not already been adopted, to have a material impact on the Company's Consolidated Financial Statements.
 In November 2023, the FASB issued ASU 2023-07, Segment
 Reporting (Topic 280)-Improvements to Reportable Segment Disclosures. The ASU enhances disclosure of significant segment expenses by requiring disclosure of significant segment expenses regularly provided to the chief operating decision maker, extend certain annual disclosures to interim periods, and permits more than one measure of segment profit or loss to be reported under certain conditions. The amendments are effective for the Company in years beginning after December 15, 2023, and interim periods within years beginning after December 15, 2024. The Company is currently evaluating the impact that the adoption of this ASU will have on its consolidated financial statements.
 In December 2023, the FASB issued ASU 2023-09, Income
 Taxes (Topic 740)-Improvements to Income Tax Disclosures. The ASU requires additional quantitative and qualitative income tax disclosures to allow readers of the consolidated financial statements to assess how the Company's operations, related tax risks and tax planning affect its tax rate and prospects for future cash flows. For public business entities, the ASU is effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact that the adoption of this ASU will have on its consolidated financial statements.
 Note 2—Acquisition
 On November 9, 2023, the Company completed its acquisition of P3, a privately-owned custom turbomachinery engineering, product development, and manufacturing business located in Jupiter, FL that serves the space, new energy, defense, and medical industries. The Company believes this acquisition advances its growth strategy, further diversifies its market and product offerings, and broadens its turbomachinery solutions. P3 will be managed through the Company's Barber-Nichols, LLC subsidiary and is highly complementary to BN's technology and enhances its turbomachinery solutions.

 This transaction was accounted for as a business combination which requires that assets acquired and liabilities assumed be recognized at their fair value as of the acquisition date. The purchase price of $11,238 was comprised of 125 shares of the Company's common stock, representing a value of $1,930, and cash consideration of $7,098, subject to certain potential adjustments, including a customary working capital adjustment. The cash consideration was funded through borrowings on the Company's line of credit. The purchase agreement included a contingent earn-out
 dependent upon certain financial measures of P3 post-acquisition, in which the sellers are eligible to receive up to $3,000 in additional cash consideration. At November 9, 2023, a liability of $2,040 was recorded for the contingent earn-out.
 A rollforward of the P3 contingent earn-out
 liability since the date of acquisition is as follows:

 The change in fair value of the contingent earn-out
 liability was included in Other operating (income) expense, net in the Consolidated Statements of Operations. Acquisition and integration costs of $352 were expensed in the year ended March 31, 2024, and are included in Selling, general and administrative expenses in the Consolidated Statement of Operations.
 The cost of the acquisition was allocated to the assets acquired and liabilities assumed based upon their estimated fair value at the date of acquisition and the amount exceeding the fair value of $1,997 was recorded as goodwill, which is deductible for tax purposes. Goodwill generated in the acquisition is related to P3's assembled workforce, synergies between Graham's other operations and P3 that are expected to occur as a result of the combined engineering knowledge, the ability of each of the operations to leverage each other's technology solutions, and Graham's ability to utilize acquired management knowledge in providing complementary product offerings to the Company's customers.

 The fair value of acquisition-related intangible assets includes customer relationships, technology and technical know-how,
 and tradename. The tradename is included in the line item "Other intangible assets, net" in the Consolidated Balance Sheets. The fair value of customer relationships was calculated using an income approach, specifically the Multi Period Excess Earnings method, which incorporates assumptions regarding retention rate, new customer growth and customer related costs. The fair value of tradename and technology and technical know-how
 were both calculated using a Relief from Royalty method, which develops a market based royalty rate used to reflect the after tax royalty savings attributable to owning the intangible asset.
 Customer relationships and tradename are amortized in Selling, general and administrative expense on a straight line basis over their estimated useful lives of eight years and three years respectively. Technology and technical know-how
 is amortized in Cost of products sold on a straight line basis over its estimated useful life of ten years.
 The Consolidated Statement of Operations for the year ended March 31, 2024 includes net sales of P3 of $2,206 and net income of $24.

 Note 3 – Revenue Recognition:
 The Company recognizes revenue on all contracts when control of the product is transferred to the customer. Control is generally transferred when products are shipped, title is transferred, significant risks of ownership have transferred, the Company has rights to payment, and rewards of ownership pass to the customer.

 A performance obligation represents a promise in a contract to provide a distinct good or service to a customer. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Transaction price reflects the amount of consideration to which the Company expects to be entitled in exchange for transferred products. A contract's transaction price is allocated to each distinct performance obligation and revenue is recognized as the performance obligation is satisfied. In certain cases, the Company may separate a contract into more than one performance obligation, while in other cases, several products may be part of a fully integrated solution and are bundled into a single performance obligation. If a contract is separated into more than one performance obligation, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods underlying each performance obligation. The Company has made an accounting policy election to exclude from the measurement of the contract price all taxes assessed by government authorities that are collected by the Company from its customers. The Company does not adjust the contract price for the effects of a financing component if the Company expects, at contract inception, that the period between when a product is transferred to a customer and when the customer pays for the product will be one year or less.
 The Company recognizes revenue over time when contract performance results in the creation of a product for which the Company does not have an alternative use and the contract includes an enforceable right to payment in an amount that corresponds directly with the value of the performance completed. To measure progress towards completion on performance obligations for which revenue is recognized over time the Company utilizes an input method based upon a ratio of direct labor hours incurred to date to management's estimate of the total labor hours to be incurred on each contract, an input method based upon a ratio of total contract costs

 incurred to date to management's estimate of the total contract costs to be incurred or an output method based upon completion of operational milestones, depending upon the nature of the contract. The Company has established the systems and procedures essential to developing the estimates required to account for performance obligations over time. These procedures include monthly review by management of costs incurred, progress towards completion, identified risks and opportunities, sourcing determinations, changes in estimates of costs yet to be incurred, availability of materials, and execution by subcontractors. Sales and earnings are adjusted on a cumulative catch-up
 basis in current accounting periods based upon revisions in the contract value due to pricing changes and estimated costs at completion. Losses on contracts are recognized immediately when evident to management. Revenue on the majority of the Company's contracts, as measured by number of contracts, is recognized upon shipment to the customer. Revenue on larger contracts, which are fewer in number but generally represent the majority of revenue, is recognized over time as these contracts meet specific criteria established in ASC 606. The following table presents the Company's revenue percentages disaggregated by revenue recognized over time or upon shipment:

 The timing of revenue recognition, invoicing and cash collections affect trade accounts receivable, unbilled revenue (contract assets) and customer deposits (contract liabilities) on the Consolidated Balance Sheets. Unbilled revenue represents revenue on contracts that is recognized over time and exceeds the amount that has been billed to the customer. Unbilled revenue is separately presented in the Consolidated Balance Sheets. The Company may receive a progress payment from a customer, which is recorded as a customer deposit or have an unconditional right to receive a customer deposit prior to revenue being recognized. Because the performance obligations related to such customer deposits may not have been satisfied, a contract liability is recorded and an offsetting asset of equal amount is recorded as a trade accounts receivable until the deposit is collected. Customer deposits are separately presented in the Consolidated Balance Sheets. Customer deposits are not considered a significant financing component as they are generally received less than one year before the product is completed or used to procure specific material on a contract, as well as related overhead costs incurred during design and construction.

Trade accounts receivable, as presented on the Consolidated Balance Sheets, includes corresponding balances at March 31, 2024 and 2023, respectively.
 Receivables billed but not paid under retainage provisions in the Company's customer contracts were $1,875 and $2,542 at March 31, 2024 and 2023, respectively.
 The Company's remaining unsatisfied performance obligations represent a measure of the total dollar value of work to be performed on contracts awarded and in progress. The Company also refers to this measure as backlog. As of March 31, 2024, the Company had remaining unsatisfied performance obligations of $390,868. The Company expects to recognize revenue on approximately 35% to 40% of the remaining performance obligations within one year, 25% to 30% in one to two years and the remaining beyond two years.

 Note 8—Leases:
 The Company leases certain manufacturing facilities, office space, machinery and office equipment. An arrangement is considered to contain a lease if it conveys the right to use and control an identified asset for a period of time in exchange for consideration. If it is determined that an arrangement contains a lease, then a classification of a lease as operating or finance is determined by evaluating the five criteria outlined in the lease accounting guidance at inception. Leases generally have remaining terms of one year to five years, whereas leases with an initial term of twelve months or less are not recorded on the Consolidated Balance Sheets. The depreciable life of leased assets related to finance leases is limited by the expected term of the lease, unless there is a transfer of title or purchase option that the Company believes is reasonably certain of exercise. Certain leases include options to renew or terminate. Renewal options are exercisable per the discretion of the Company and vary based on the nature of each lease. The term of the lease includes renewal periods only if the Company is reasonably certain that it will exercise the renewal option. When determining if a renewal option is reasonably certain of being exercised, the Company considers several factors, including but not limited to, the cost of moving to another location, the cost of disrupting operations, whether the purpose or location of the leased asset is unique and the contractual terms associated with extending the lease. The Company's lease agreements do not contain any residual value guarantees or any material restrictive covenants and the Company does not sublease to any third parties. As of March 31, 2024, the Company did not have any material leases that have been signed but not commenced.

 Right-of-use

 ("ROU") lease assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make payments in exchange for that right of use. Finance lease ROU assets and operating lease ROU assets are included in the line items Property, plant and equipment, net and Operating lease assets, respectively, in the Consolidated Balance Sheets. The current portion and non-current
 portion of finance and operating lease liabilities are all presented separately in the Consolidated Balance Sheets.
 The Company previously entered into operating leases with Ascent Properties Group, LLC ("Ascent"), a limited liability company of which our Chief Executive Officer holds a majority interest, for an office and manufacturing building in Arvada, CO as well as machinery and equipment. During fiscal 2023, the Company entered into an additional lease with Ascent for another manufacturing building in Arvada, CO. In connection with such leases, the Company made fixed minimum lease payments to the lessor of $952, $843 and $707 in fiscal 2024, 2023 and 2022, respectively. Future minimum lease payments under these leases as of March 31, 2024 are $5,785.
 The discount rate implicit within the Company's leases is generally not readily determinable, and therefore, the Company uses an incremental borrowing rate in determining the present value of lease payments based on rates available at commencement.

 Note 9 - Debt:
 On October 13, 2023, the Company terminated its revolving credit facility and repaid its term loan with Bank of America and entered into a new five-year revolving credit facility with Wells Fargo Bank, National Association ("Wells Fargo") that provides a $35,000 line of credit and automatically increases to $50,000 upon the Company satisfying specified covenants (the "New Revolving Credit Facility"). The additional $15,000 will automatically be available upon (a) the Company achieving a minimum consolidated EBITDA, as defined in the agreement, of $15,000, computed on a trailing twelve month basis, for three consecutive quarters and (b) a minimum liquidity (consisting of cash and borrowing availability under the New Revolving Credit Facility) for the Company of at least $7,500. The New Revolving Credit Facility has a $25,000 sub-limit
 for letters of credit and the Company may request the issuance of cash secured letters of credit in an aggregate amount of up to $7,500. As of March 31, 2024, there was $0 borrowed and $1,890 letters of credit outstanding on the New Revolving Credit Facility.
 Long term debt is comprised of the following:

 The New Revolving Credit Facility contains customary terms and conditions, including representations and warranties and affirmative and negative covenants, as well as financial covenants for the benefit of Wells Fargo, which require the Company to maintain (i) a consolidated total leverage ratio not to exceed 3.50:1.00 and (ii) a consolidated fixed charge coverage ratio of at least 1.20:1.00, in both cases computed in accordance with the definitions and requirements specified in the New Revolving Credit Facility. As of March 31, 2024, the Company was in compliance with the financial covenants of the New Revolving Credit Facility.
 Borrowings under the New Revolving Credit Facility bear interest at a rate equal to, at the Company's option, either (i) a forward-looking term rate based on the secured overnight financing rate ("SOFR") for the applicable interest period, subject to a floor of 0.0% per annum or (ii) a base rate determined by reference to the highest of (a) the rate of interest per annum publicly announced by the Lender as its prime rate, (b) the federal funds rate plus 0.50% per annum and (c) one-month
 term SOFR plus 1.00% per annum, subject to a floor of 1.00% per annum, plus, in each case, an applicable margin. The applicable margins range between (i) 1.25% per annum and 2.50% per annum in the case of any term SOFR loan and (ii) 0.25% per annum and 1.50% per annum in the case of any base rate loan, in each case based upon the Company's then-current consolidated total leverage ratio; provided, however, for a period of one year following the closing date, the applicable margin shall be set at 1.25% per annum in the case of any term SOFR loan and 0.25% per annum in the case of any base rate loan. As of March 31, 2024, the SOFR rate was 5.34%.
 The Company is required to pay a quarterly commitment fee on the unused portion of the New Revolving Credit Facility during the applicable quarter at a per annum rate also determined by reference to the Company's then-current consolidated total leverage ratio, which fee ranges between 0.10% per annum and 0.20% per annum; provided, however, for a period of one year following the closing date, the quarterly commitment fee will be set at 0.10% per annum. Any outstanding letters of credit that are cash secured will bear a fee equal to the daily amount available to be drawn under such letters of credit multiplied by 0.65% per annum. Any outstanding letters of credit issued under the New Revolving Credit Facility will bear a fee equal to the daily amount drawn under such letters of credit multiplied by the applicable margin for term SOFR loans. As of March 31, 2024, the amount available under the New Revolving Credit Facility was $33,110, subject to the interest and leverage covenants.
 In connection with the termination of the old revolving credit facility and term loan with Bank of America, the Company paid $752 in exit costs and recognized an extinguishment charge of $726.
 As of March 31, 2024, $1,592 letters of credit remain outstanding with Bank of America and are cash secured. These outstanding letters of credit are subject to a fee of 0.60% per annum. As of March 31, 2024, $4,780 letters of credit are outstanding with HSBC Bank USA, N.A and are cash secured. These outstanding letters of credit are subject to a fee of between 0.75% and 0.85% per annum, depending on the term of the letter of credit. As of March 31, 2024, $180 letters of credit are outstanding with China Construction Bank and are cash secured. Additionally, we have a 10,000 RMB bank guaranty line of credit with China Citic Bank Co. LTD which had $0 letters of credit outstanding at March 31, 2024. Outstanding letters of credit under this agreement are subject to a fee of 0.60% per annum. Total letters of credit outstanding as of March 31, 2024 and March 31, 2023 were $8,442 and $12,842, respectively.

 Note 10 - Financial Instruments and Derivative Financial Instruments:
 Concentrations of Credit Risk

 Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, and trade accounts receivable. The Company places its cash, cash equivalents with high credit quality financial institutions, and evaluates the credit worthiness of these financial institutions on a regular basis. Concentrations of credit risk with respect to trade accounts receivable are limited due to the large number of customers comprising the Company's customer base and their geographic dispersion. At March 31, 2024 and 2023, the Company had no significant concentrations of credit risk.
 Letters of Credit

 The Company has entered into standby letter of credit agreements with financial institutions relating to the guarantee of future performance on certain contracts. At March 31, 2024 and 2023, the Company was contingently liable on outstanding standby letters of credit aggregating $8,442 and $12,842, respectively.
 Fair Value of Financial Instruments

 The estimates of the fair value of financial instruments are summarized as follows:
 Cash and cash equivalents
: The carrying amount of cash and cash equivalents approximates fair value due to the short-term maturity of these instruments and are considered Level 1 assets in the fair value hierarchy.
 Short-term and long-term debt
: The carrying values of credit facilities with variable rates of interest approximates fair values and is considered a Level 2 liability in the fair value hierarchy.

 Deferred income taxes include the impact of state investment tax credits of $236, which expire from 2025 to 2037 and state investment tax credits of $794, which have an unlimited carryforward period.
 In assessing the realizability of deferred tax assets, management considers, within each taxing jurisdiction, whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based on the consideration of the weight of both positive and negative evidence, management determined that a portion of the deferred tax assets as of March 31, 2024 and 2023 related to certain state investment tax credits and the capital loss related to Energy Steel would not be realized, and recorded a valuation allowance of $5,241 and $5,277, respectively.

 The Company files federal and state income tax returns in several domestic and international jurisdictions. In most tax jurisdictions, returns are subject to examination by the relevant tax authorities for a number of years after the returns have been filed. The Company is subject to U.S. federal examination for tax years 2020 through 2023 and examination in state tax jurisdictions for tax years 2019 through 2023. The Company is subject to examination in the People's Republic of China for tax years 2020 through 2023 and in India for tax years 2018 through 2022. The liability for unrecognized tax benefits was $0 at each of March 31, 2024 and 2023.
 Note 12 – Employee Benefit Plans:
 Retirement Plans
 The Company has a qualified defined benefit plan covering Batavia based employees hired prior to January 1, 2003, which is non-contributory.
 Benefits are based on the employee's years of service and average earnings for the five highest consecutive calendar years of compensation in the ten-year
 period preceding retirement. The Company's funding policy for the plan is to contribute the amount required by the Employee Retirement Income Security Act of 1974, as amended.

 During fiscal 2024 and fiscal 2023, the pension plan released liabilities for vested benefits of certain participants through the purchase of nonparticipating annuity contracts with a third-party insurance company. As a result of these transactions, in fiscal 2024 and fiscal 2023, the projected benefit obligation and plan assets decreased $1,452 and $1,383, respectively. The projected benefit obligation is the actuarial present value of benefits attributable to employee service rendered to date, including the effects of estimated future pay increases. The accumulated benefit obligation reflects the actuarial present value of benefits attributable to employee service rendered to date, but does not include the effects of estimated future pay increases. The accumulated benefit obligation as of March 31, 2024 and 2023 was $22,398 and $23,784, respectively. At March 31, 2024 and 2023, the pension plan was fully funded on an accumulated benefit obligation basis.

 The investment strategy of the plan is to generate a consistent total investment return sufficient to pay present and future plan benefits to retirees, while minimizing the long-term cost to the Company. Target allocations for asset categories are used to earn a reasonable rate of return, provide required liquidity and minimize the risk of large losses. Targets are adjusted when considered necessary to reflect trends and developments within the overall investment environment.

 The fair value of Level 1 pension assets is obtained by reference to the last quoted price of the respective security on the market which it trades. See Note 1 to the Consolidated Financial Statements.

 On February 4, 2003, the Company closed the defined benefit plan to all employees hired on or after January 1, 2003. In place of the defined benefit plan, these employees participate in the Company's domestic defined contribution plan. The Company contributes a fixed percentage of employee compensation to this plan on an annual basis for these employees. The Company's contribution to the defined contribution plan for these employees in fiscal 2024, fiscal 2023 and fiscal 2022 was $1,237, $1,030 and $710, respectively.
 The Company has an unfunded Supplemental Executive Retirement Plan ("SERP") which provides retirement benefits associated with wages in excess of the legislated qualified plan maximums. Pension expense recorded in fiscal 2024, fiscal 2023, and fiscal 2022 related to this plan was $54, $74 and $346, respectively. The weighted average discount rate used to determine pension expense for this plan was 5.01%, 3.64% and 3.21% for fiscal 2024, fiscal 2023 and fiscal 2022, respectively. The weighted average rate of increase in compensation levels used to develop pension expense for this plan was 3% in each of fiscal 2024, fiscal 2023 and fiscal 2022. At March 31, 2024 and 2023, the projected benefit obligation was $1,060 and $1,104, respectively, and is included in the caption "Accrued Pension and Postretirement Benefit Liabilities" in the Consolidated Balance Sheets. The amounts recognized in accumulated other comprehensive loss, net of income tax, consist of a net actuarial loss of ($69) and ($47) at March 31, 2024 and 2023, respectively.
 The Company has a domestic defined contribution plan (401(k)) covering substantially all employees. The Company provides matching contributions equal to 100% of the first 3% of an employee's salary deferral and 50% of the next 2% percent of an employee's salary deferral. Company contributions are immediately vested. Contributions were $1,914 in fiscal 2024, $1,904 in fiscal 2023 and $1,365 in fiscal 2022.
 Other Postretirement Benefits
 In addition to providing pension benefits, the Company has a plan in the U.S. that provides health care benefits for eligible retirees and eligible survivors of retirees. The Company's share of the medical premium cost has been capped at $4 for family coverage and $2 for single coverage for early retirees, and $1 for both family and single coverage for regular retirees.
 On February 4, 2003, the Company terminated postretirement health care benefits for its U.S. employees. Benefits payable to retirees of record on April 1, 2003 remained unchanged.

 Note 15—Segment Information:
 The Company has one reporting segment as its operating segments meet the requirements for aggregation. The Company and its operating subsidiaries design and manufacture mission critical fluid, power, heat transfer and vacuum technologies for the defense, space, energy and process industries. The Company also services and sells spare parts for its equipment.
 See Note 3 to the Consolidated Financial Statements for net sales by market and geographic area.
 In fiscal 2024, the Company had two customers whose sales amounted to 16% and 15% of total consolidated net sales. In fiscal 2023, the Company had two customers whose sales amounted to 15% and 12% of total consolidated net sales. In fiscal 2022, the Company had two customers whose sales amounted to 12% and 10% of total consolidated net sales. One customer representing such sales was the same customer in fiscal 2024, fiscal 2023 and fiscal 2022.
 Note 16 – Purchase of Treasury Stock:
 On January 29, 2015, the Company's Board of Directors authorized a stock repurchase program. Under the stock repurchase program the Company is permitted to repurchase up to $18,000 of its common stock either in the open market or through privately negotiated transactions. Cash on hand has been used to fund all stock repurchases under the program. No shares were purchased under this program in fiscal 2024, fiscal 2023 or fiscal 2022. Under the terms of our credit agreement with Wells Fargo, the Company cannot repurchase shares of its common stock if the Company is in default or if such repurchase would result in an event of default under the credit agreement.
 Note 17 – Commitments and Contingencies:
 The Company has been named as a defendant in lawsuits alleging personal injury from exposure to asbestos allegedly contained in, or accompanying, products made by the Company. The Company is a co-defendant
 with numerous other defendants in these lawsuits and intends to vigorously defend itself against these claims. The claims in the Company's current lawsuits are similar to those made in previous asbestos-related suits that named the Company as a defendant, which either were dismissed when it was shown that the Company had not supplied products to the plaintiffs' places of work or were settled for immaterial amounts. The Company cannot provide any assurances that any pending or future matters will be resolved in the same manner as previous lawsuits.

 During the third quarter of fiscal 2024, the Audit Committee of the Board of Directors, with the assistance of external counsel and forensic professionals, concluded an investigation into a whistleblower complaint received regarding GIPL. The investigation identified both evidence supporting the complaint and other misconduct by employees. The other misconduct totaled $150 over a period of four years and was isolated to GIPL. All involved employees have been terminated and the Company has implemented remedial actions, including strengthening its compliance program and internal controls. As a result of the investigation, during the third quarter of fiscal 2024, the statutory auditor and bookkeeper of GIPL tendered their resignations and new firms were appointed. The Company has voluntarily reported the findings of its investigation to the appropriate authorities in India and the U.S. Department of Justice and the Securities and Exchange Commission. Although the resolutions of these matters are inherently uncertain, we do not believe any remaining impact will be material to the Company's overall consolidated results of operations, financial position, or cash flows.
 As of March 31, 2024, the Company was subject to the claims noted above, as well as other legal proceedings and potential claims that have arisen in the ordinary course of business. Although the outcome of the lawsuits, legal proceedings or potential claims to which the Company is, or may become, a party to cannot be determined and an estimate of the reasonably possible loss or range of loss cannot be made for the majority of the claims, management does not believe that the outcomes, either individually or in the aggregate, will have a material effect on the Company's results of operations, financial position or cash flows.
 Note 18 - Other Operating (Income) Expense, Net:
 During the fourth quarter ended March 31, 2024, the Company adjusted the earn-out
 value related to the acquisition of P3 (see Note 2), therefore the Company recognized a change in fair value of the contingent liability in the amount $80, which was included in Other operating expense (income), net in the Consolidated Statement of Operations in fiscal 2024.
 On November 29, 2021, the Company and Jeffrey F. Glajch entered into a Severance and Transition Agreement (the "Agreement") pursuant to which Mr. Glajch agreed to retire from his position the earlier of June 30, 2022 or as of a date upon which the Company and Mr. Glajch otherwise mutually agreed. On March 27, 2022, the Company and Mr. Glajch entered into an Amended and Restated Severance and Transition Agreement (the "Amended Agreement") in which Mr. Glajch agreed to retire on April 15, 2022. Mr. Glajch agreed to provide certain transition-related services to the Company for a period of nine months following the date of separation. The Amended Agreement also provides that the company will pay Mr. Glajch a severance payment in an amount equal to nine months of Mr. Glajch's base salary commencing in April 2022 as well as health care premiums. As a result, expense of $275 is recognized and included in Other operating expense (income), net in the Consolidated Statement of Operations in fiscal 2022. As of March 31, 2024 and March 31, 2023, the liability was zero.
 On August 9, 2021, the Company and James R. Lines entered into a Severance and Transition Agreement (the "Transition Agreement") pursuant to which Mr. Lines resigned from his position as the Company's Chief Executive Officer and as a member of the Board of Directors, and from positions he holds with all Company subsidiaries and affiliates, effective as of the close of business on August 31, 2021. The Transition Agreement provides that for a period of 18 months following the separation date, Mr. Lines is paid his base salary as well as health care premiums. As a result, expense of $798 is recognized and included in Other operating expense (income), net in the Consolidated Statement of Operations in fiscal 2022. As of March 31, 2024 and March 31, 2023, the liability was zero.
 During the second quarter ended September 30, 2021, the Company terminated the earn-out
 agreement related to the acquisition of BN, therefore the Company recognized a change in fair value of the contingent liability in the amount $1,900, which was included in Other operating expense (income), net in the Consolidated Statement of Operations in fiscal 2022.
 Item 9A. Controls and Procedures
 Conclusion Regarding Disclosure Controls and Procedures

 Management, including our President and Chief Executive Officer (principal executive officer) and Vice President–Finance and Chief Financial Officer (principal financial officer) has evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Form 10-K.
 Based upon, and as of the date of that evaluation, our President and Chief Executive Officer and Vice President–Finance and Chief Financial Officer (principal financial officer) concluded that the disclosure controls and procedures were effective, in all material respects, to ensure that information required to be disclosed in the reports we file and submit under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is (i) recorded, processed, summarized and reported as and when required and (ii) is accumulated and communicated to our management, including our President and Chief Executive Officer and Vice President-Finance and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

 Changes in Internal Control Over Financial Reporting

 Other than the events discussed under the section entitled "P3 Technologies, LLC Acquisition" below, there has been no change to our internal control over financial reporting during the fourth quarter of the fiscal year covered by this Annual Report on Form 10-K
 that has materially affected, or that is reasonably likely to materially affect our internal control over financial reporting.
 P3 Technologies, LLC Acquisition

 On November 9, 2023, we acquired P3 Technologies, LLC, a privately-owned custom turbomachinery engineering, product development, and manufacturing business that serves the space, new energy and medical industries. For additional information regarding the acquisition, refer to Note 2 to the Consolidated Financial Statements included in Item 8 in this Annual Report on Form 10-K
 and Management's Discussion and Analysis of Financial Condition and Results of Operations included in Item 7 in this Annual Report on Form 10-K.
 Based on the recent completion of this acquisition and, pursuant to the Securities and Exchange Commission's guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment for a period not to exceed one year form the date of acquisition, the scope of our assessment of the effectiveness of internal control over financial reporting as of the end of the period covered by this report does not include P3 Technologies, LLC.
 We are in the process of implementing our internal control structure over P3 Technologies, LLC and we expect that this effort will be completed during the fiscal year ending March 31, 2025.
 Management's Annual Report on Internal Control over Financial Reporting

 Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f).
 A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our organization have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving our stated goals under all potential future conditions. Moreover, over time controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in the design of an internal control system, misstatements due to error or fraud may occur and not be detected. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.
 Under the supervision and with the participation of management, including our President and Chief Executive Officer (principal executive officer) and Vice President–Finance and Chief Financial Officer (principal financial officer) we conducted an assessment of the effectiveness of our internal control over financial reporting based on the framework established in Internal Control–Integrated Framework
 (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the assessment under this framework, management concluded that our internal control over financial reporting was effective as of March 31, 2024.
 The effectiveness of our internal control over financial reporting as of March 31, 2024 has been audited by Deloitte & Touche LLP, our independent registered public accounting firm, as stated in their report included in this Annual Report.
 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 To the stockholders and the Board of Directors of Graham Corporation
 Opinion on Internal Control over Financial Reporting
 We have audited the internal control over financial reporting of Graham Corporation and subsidiaries (the "Company") as of March 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013)
 issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013)
 issued by COSO.
 We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended March 31, 2024, of the Company and our report dated June 7, 2024, expressed an unqualified opinion on those financial statements.
 As described in Management's Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at P3 Technologies, LLC, which was acquired on November 9, 2023, and whose financial statements constitute 5% and 5% of net and total assets, respectively, 1% of revenues, and less than 1% of net income of the consolidated financial statement amounts as of and for the year ended March 31, 2024. Accordingly, our audit did not include the internal control over financial reporting at P3 Technologies, LLC.

 Basis for Opinion
 The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
 We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
 Definition and Limitations of Internal Control over Financial Reporting
 A company's 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 generally accepted accounting principles. A company's 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.
 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.
