IMMEDIATE RELEASE

Graham Corporation Reports Fourth Quarter and Full-Year Fiscal 2025 Results

BATAVIA, NY, June 9, 2025 – Graham Corporation (NYSE: GHM) (“GHM” or the “Company”), a global leader in the design and manufacture of mission critical fluid, power, heat transfer and vacuum technologies for the Defense, Energy & Process, and Space industries, today reported financial results for the fourth quarter and fiscal year 2025 ending March 31, 2025 (“fiscal 2025”).

“We closed fiscal 2025 with strong momentum, as our fourth quarter results reflected solid execution and sustained demand across our diversified product portfolio,” said Daniel J. Thoren, Chief Executive Officer. “We continue to advance projects with an expected 20%+ ROIC1, including automated welding, the expansion of our Batavia, NY facility, and a new cryogenic testing facility in Florida, which will drive enhanced margins and create additional revenue opportunities.”

Mr. Thoren continued, “Looking ahead to fiscal 2026, we are well-positioned to achieve our long-term growth and profitability targets and are strategically looking to invest in key organic and inorganic growth opportunities.”

Management Transition

As previously announced on February 6, 2025, Graham began a planned management transition aligned with its succession strategy. Effective June 10, 2025, Chief Executive Officer Daniel J. Thoren will transition to Executive Chairman and Strategic Advisor. Matt Malone, currently President and Chief Operating Officer, will succeed him as CEO.

Jonathan W. Painter, Chairman of the Board, will transition to Lead Independent Director. Additionally, Michael E. Dixon, promoted to General Manager of Barber-Nichols in February 2025, will assume the role of Vice President of Graham Corporation and General Manager of Barber-Nichols.

“It has been a career highlight and honor to lead Graham Corporation over the last four years and I want to thank our Board and each one of our employees for their commitment and belief in our mission to build better companies, supply mission critical equipment to our customers, and deliver superior performance to our investors” said Mr. Thoren. “The company is well positioned to achieve its 2027 goals we set in 2022, and I have every confidence in Matt to lead the company to even greater achievements beyond that.”

Fourth Quarter Fiscal 2025 Performance Review

(All comparisons are with the same prior-year period unless noted otherwise.)

We have updated our end market disclosures to better align with how management evaluates the business and product portfolio. As part of this change, revenue previously classified as Refining, Chemical/Petrochemical, and Other, which included New Energy product sales, will now be consolidated into one market, which has been renamed “Energy & Process.” The Defense and Space end market classifications remain unchanged. Prior period amounts have been updated to reflect this change.

Quarterly net sales of $59.3 million increased 21%, or $10.3 million. Sales to the Defense market grew by $7.7 million, or 28% from the prior year period, driven by growth in existing programs, better execution, improved pricing, and the timing of key project milestones. Energy & Process sales contributed $1.8 million to growth driven by increased sales of capital equipment to foreign markets and higher aftermarket sales. Aftermarket sales to the Energy & Process and Defense markets of $12.1 million remained strong and were 3.3% higher than the prior year. See supplemental data for a further breakdown of sales by market and region.

Gross profit for the quarter increased $3.3 million to $16.0 million compared to the prior-year period of $12.7 million. As a percentage of sales, gross profit margin increased 110 basis points to 27.0%, compared to the fiscal fourth quarter of 2024. This increase was driven by leverage on higher volume, better execution, and improved pricing, partially offset by higher incentive compensation compared to the prior year period.

Selling, general and administrative expense (“SG&A”), including amortization, totaled $10.8 million, or 18.1% of sales, down $0.3 million compared with the prior year. This decrease reflects the timing of various project expenses partially offset by higher salaries and performance-based compensation as we continue to invest in our people, our processes and our technology to drive long-term sustainable growth.

Full Year Fiscal 2025 Performance Review

(All comparisons are with the same prior-year period unless noted otherwise.)

Net sales of $209.9 million increased 13%, or $24.4 million. Incremental revenue from the acquisition of P3 Technologies (“P3”) in November 2023 accounted for $2.8 million of this increase. Sales to the Defense market grew by $22.4 million, or 23% from the prior year, driven by the addition of new Defense programs, the growth of existing programs, better execution, improved pricing and the timing of key project milestones. Additionally, net sales to the Space industry for fiscal 2025 increased 11% over the prior year primarily due to the addition of P3. Finally, net sales to the Energy & Process industry for fiscal 2025 was consistent with the prior year as increased sales to Asia and the Middle-East were offset by a $2.7 million decline in aftermarket sales from the record levels of fiscal 2024, but which remain strong. See supplemental data for a further breakdown of sales by market and region.

Gross profit for the year increased $12.3 million to $52.9 million compared to the prior-year period of $40.6 million. As a percentage of sales, gross profit margin increased 330 basis points to 25.2%, compared to fiscal 2024. This increase was driven by leverage on higher volume, better execution, and improved pricing. Additionally, fiscal 2025 gross profit benefited $1.3 million from a grant received from the BlueForge Alliance earlier this fiscal year to reimburse Graham for the cost of the Company’s Defense welder training programs in Batavia and related equipment. The Company currently does not expect to receive any additional welder training grants in fiscal 2026.

SG&A, including amortization, totaled $38.9 million, or 18.5% of sales, up $5.3 million compared with the prior year. This increase reflects the Company’s continued investments in its people, processes, and technology to drive long-term sustainable growth including costs related to the implementation of a new enterprise resource planning (“ERP”) system at our Batavia facility, incremental costs related to P3, and increased research and development investment, among others.

Cash Management and Balance Sheet

Cash provided by operating activities totaled $24.3 million for the year-ending March 31, 2025, a decrease of $3.8 million from the comparable period in fiscal 2024. As of March 31, 2025, cash and cash equivalents were $21.6 million, up from $16.9 million at the end of fiscal 2024.

Capital expenditures for fiscal 2025 were $19.0 million, focused on capacity expansion, increasing capabilities, and productivity improvements. All major capital projects are on time and on budget.

The Company had no debt outstanding March 31, 2025 with $44.7 million available on its revolving credit facility after taking into account outstanding letters of credit.

Orders, Backlog, and Book-to-Bill Ratio

See supplemental data filed with the Securities and Exchange Commission on Form 8-K and provided on the Company’s website for a further breakdown of orders and backlog by market. See “Key Performance Indicators” below for important disclosures regarding Graham’s use of these metrics ($in millions).

Orders for the fourth quarter of fiscal 2025 increased to $86.9 million, including $50.0 million, of a $136.5 million total contract value, to procure long-lead time materials for follow-on contracts to support the U.S. Navy’s Virginia Class Submarine program. Aftermarket orders for the Energy & Process and Defense markets remained strong and totaled $11.8 million for the fourth quarter of fiscal 2025, an increase of 50% over the prior year.

For fiscal 2025, orders decreased to $231.1 million, primarily due to a record level of orders in fiscal 2024 as a result of follow-on orders for critical U.S. Navy programs related to the Columbia Class submarine and Ford Class carrier programs. Aftermarket orders in fiscal 2025 for the Energy & Process, and Defense markets increased 8% to $46.6 million, compared with fiscal 2024.

Orders tend to be lumpy given the nature of our business (i.e. large capital projects) and in particular, orders to the Defense industry, which span multiple years and can be significantly larger in size. Book-to-bill for fiscal 2025 was 1.1x.

Backlog as of March 31, 2025, was $412.3 million, a 5% increase over the prior-year period. Approximately 45% of orders currently in backlog are expected to be converted to sales in the next twelve months and another 25% to 30% are expected to convert to sales within one to two years. Approximately 83% of our backlog at March 31, 2025 was to the Defense industry, which we believe provides stability and visibility to our business.

Fiscal 2026 Outlook

“I am pleased to announce our fiscal 2026 outlook, which reflects the continued momentum in our business and the initial impacts of the strategic investments we have made. The Company is deploying capital to support our organic and inorganic growth initiatives, while making strategic improvements to enhance our operations and drive margin expansion, which is being enabled by our strong balance sheet. The outlook we are providing reflects the expected impact of tariffs on our fiscal 2026 results, which we estimate to be approximately $2.0 million to $5.0 million. This is subject to change based on the fluidity of global trade policy” said Christopher Thome, Chief Financial Officer.

Our expectations for sales and profitability assumes that we will be able to operate our production facilities at planned capacity, have access to our global supply chain including our subcontractors, do not experience any global disruptions, and experience no impact from any other unforeseen events.

Non-GAAP Financial Measures

Adjusted EBITDA is defined as consolidated net income (loss) before net interest expense, income taxes, depreciation, amortization, other acquisition related expenses, and other unusual/nonrecurring expenses. Adjusted EBITDA margin is defined as Adjusted EBITDA as a percentage of sales. Adjusted EBITDA and Adjusted EBITDA margin are not measures determined in accordance with generally accepted accounting principles in the United States, commonly known as GAAP. Nevertheless, Graham believes that providing non-GAAP information, such as Adjusted EBITDA and Adjusted EBITDA margin, is important for investors and other readers of Graham’s financial statements, as it is used as an analytical indicator by Graham’s management to better understand operating performance. Moreover, Graham’s credit facility also contains ratios based on Adjusted EBITDA. Because Adjusted EBITDA and Adjusted EBITDA margin are non-GAAP measures and are thus susceptible to varying calculations, Adjusted EBITDA, and Adjusted EBITDA margin, as presented, may not be directly comparable to other similarly titled measures used by other companies.

Adjusted net income and adjusted net income per diluted share are defined as net income and net income per diluted share as reported, adjusted for certain items and at a normalized tax rate. Adjusted net income and adjusted net income per diluted share are not measures determined in accordance with GAAP, and may not be comparable to the measures as used by other companies. Nevertheless, Graham believes that providing non-GAAP information, such as adjusted net income and adjusted net income per diluted share, is important for investors and other readers of the Company’s financial statements and assists in understanding the comparison of the current quarter’s and current fiscal year’s net income and net income per diluted share to the historical periods’ net income and net income per diluted share. Graham also believes that adjusted net income per share, which adds back intangible amortization expense related to acquisitions, provides a better representation of the cash earnings of the Company.

ROIC is defined as a return on invested capital and is calculated by dividing net operating profit after taxes by the total invested capital. ROIC is not a measure determined in accordance with GAAP. Nevertheless, Graham believes that providing ROIC is important for investors and other readers of Graham’s financial statements, as it is used as an analytical indicator by Graham’s management to better understand profitability and efficiency of use of capital for certain projects. Because ROIC is a non-GAAP measure and is thus susceptible to varying calculations, ROIC, as presented, may not be directly comparable to other similarly titled measures used by other companies.

Forward-Looking Non-GAAP Measures

Forward-looking ROIC, adjusted EBITDA and adjusted EBITDA margin are non-GAAP measures. The Company is unable to present a quantitative reconciliation of these forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures because such information is not available, and management cannot reliably predict the necessary components of such GAAP measures without unreasonable effort largely because forecasting or predicting our future operating results is subject to many factors out of our control or not readily predictable. In addition, the Company believes that such reconciliations would imply a degree of precision that would be confusing or misleading to investors. The unavailable information could have a significant impact on the Company’s fiscal 2025 financial results. These non-GAAP financial measures are preliminary estimates and are subject to risks and uncertainties, including, among others, changes in connection with purchase accounting, quarter-end, and year-end adjustments. Any variation between the Company’s actual results and preliminary financial estimates set forth above may be material.

Key Performance Indicators

In addition to the foregoing non-GAAP measures, management uses the following key performance metrics to analyze and measure the Company’s financial performance and results of operations: orders, backlog, and book-to-bill ratio. Management uses orders and backlog as measures of current and future business and financial performance, and these may not be comparable with measures provided by other companies. Orders represent written communications received from customers requesting the Company to provide products and/or services. Backlog is defined as the total dollar value of net orders received for which revenue has not yet been recognized. Management believes tracking orders and backlog are useful as they often times are leading indicators of future performance. In accordance with industry practice, contracts may include provisions for cancellation, termination, or suspension at the discretion of the customer.

The book-to-bill ratio is an operational measure that management uses to track the growth prospects of the Company. The Company calculates the book-to-bill ratio for a given period as net orders divided by net sales.

Given that each of orders, backlog, and book-to-bill ratio are operational measures and that the Company’s methodology for calculating orders, backlog and book-to-bill ratio does not meet the definition of a non-GAAP measure, as that term is defined by the U.S. Securities and Exchange Commission, a quantitative reconciliation for each is not required or provided.

Acquisition and integration (income) expense are incremental costs that are directly related to and as a result of the P3 acquisition or the subsequent accounting for the contingent earn-out liability. These costs (income) may include, among other things, professional, consulting and other fees, system integration costs, and contingent consideration fair value adjustments. ERP implementation costs primarily relate to consulting costs (training, data conversion, and project management) incurred in connection with the ERP system being implemented throughout our Batavia, New York facility in order to enhance efficiency and productivity and are not expected to recur once the project is completed. Debt amendment costs consist of accelerated write-offs of unamortized deferred debt issuance costs and discounts, prepayment penalties and attorney fees in connection with the amendment of our credit facility in October 2023.
