Revenues for the second quarter of fiscal 2025 were $65.9 million compared with $54.5 million for the same period of fiscal 2024. The year-over-year increase was driven by organic growth and the acquisition of NWL, Inc.

The Company’s non-GAAP net income for the second quarter of fiscal 2025 was $8.9 million, or $0.20 per share, compared with a non-GAAP net income of $10.0 million, or $0.27 per share, in the same period of fiscal 2024.

McGahn, Chairman, President and CEO, AMSC. “For our second fiscal quarter, we saw strong order demand across energy and military markets, supported by tailwinds in domestic manufacturing and reliable power needs across key sectors. We are confident in our team, our execution, and very excited about the opportunities ahead in fiscal 2025."

AMSC Reports Q2 FY25 Results Page 3 Forward-Looking Statements This press release contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Any statements in this release regarding execution of our goals and strategies, including backlog; expectations regarding the third quarter of fiscal 2025; our expected GAAP and non-GAAP financial results for the quarter ending December 31, 2025; and other statements containing the words "believes," "anticipates," "plans," "expects," "will" and similar expressions, constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements represent management's current expectations and are inherently uncertain. There are a number of important factors that could materially impact the value of our common stock or cause actual results to differ materially from those indicated by such forward-looking statements. These important factors include, but are not limited to: We have not been historically profitable, which may recur in the future. Our operating results may fluctuate significantly from quarter to quarter and may fall below expectations in any particular fiscal quarter; While we generated positive operating cash flow in fiscal 2024 and the prior year, we have a history of negative operating cash flows, and we may require additional financing in the future, which may not be available to us; Our technology and products could infringe intellectual property rights of others, which may require costly litigation and, if we are not successful, could cause us to pay substantial damages and disrupt our business; Changes in exchange rates could adversely affect our results of operations; If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely financial statements could be impaired and may lead investors and other users to lose confidence in our financial data; We may be required to issue performance bonds, which restricts our ability to access any cash used as collateral for the bonds; We may not realize all of the sales expected from our backlog of orders and contracts; If we fail to implement our business strategy successfully, our financial performance could be harmed; We rely upon third-party suppliers for the components and subassemblies of many of our Grid and Wind products, making us vulnerable to supply shortages and price fluctuations, which could harm our business; Our contracts with the U.S. and Canadian governments are subject to audit, modification or termination by such governments and include certain other provisions in favor of the governments. The continued funding of such contracts may remain subject to annual legislative appropriation, which, if not approved, could reduce our revenue and lower or eliminate our profit; Changes in U.S. government defense spending could negatively impact our financial position, results of operations, liquidity and overall business; Our business and operations may be materially adversely impacted in the event of a failure or security breach of our or any critical third parties' IT Systems or Confidential Information; Failure to comply with evolving data privacy and data protection laws and regulations or to otherwise protect personal data, may adversely impact our business and financial results; Our success is dependent upon attracting and retaining qualified personnel and our inability to do so could significantly damage our business and prospects; We may acquire additional complementary businesses or technologies, which may require us to incur substantial costs for which we may never realize the anticipated benefits; A significant portion of our Wind segment revenues are derived from a single customer. If this customer’s business is negatively affected, it could adversely impact our business; Our success in addressing the wind energy market is dependent on the manufacturers that license our designs; Many of our revenue opportunities are dependent upon subcontractors and other business collaborators; Problems with product quality or product performance may cause us to incur warranty expenses and may damage our market reputation and prevent us from achieving increased sales and market share; Many of our customers outside of the United States may be either directly or indirectly related to governmental entities, and we could be adversely affected by violations of the United States Foreign Corrupt Practices Act and similar worldwide anti-bribery laws outside the United States; We have had limited success marketing and selling our superconductor products and system-level solutions, and our failure to more broadly market and sell our products and solutions could lower our revenue and cash flow; We or third parties on whom we depend may be adversely affected by natural disasters, including events resulting from climate change, and our business continuity and disaster recovery plans may not adequately protect us or our value chain from such events; Uncertainty surrounding our prospects and financial condition may have an adverse effect on our customer and supplier relationships; Pandemics, epidemics, or other public health crises may adversely impact our business, financial condition and results of operations; Adverse changes in domestic and global economic conditions could adversely affect our operating results; Our international operations are subject to risks that we do not face in the United States, which could have an adverse effect on our operating results; Our products face competition, which could limit our ability to acquire or retain customers; We have operations in, and depend on sales in, emerging markets, including India, and global conditions could negatively affect our operating results or limit our ability to expand our operations outside of these markets. Changes in India’s political, social, regulatory and economic environment may affect our financial performance; Industry consolidation could result in more powerful competitors and fewer customers; Our success could depend upon the commercial adoption of the REG system, which is currently limited, and a widespread commercial market for our REG products may not develop; Increasing focus and scrutiny on environmental sustainability and social initiatives could adversely impact our business and financial results; Growth of the wind energy market depends largely on the availability and size of government subsidies, economic incentives and legislative programs designed to support the growth of wind energy; Lower prices for other energy sources may reduce the demand for wind energy development, which could have a material adverse effect on our ability to grow our Wind business; We may be unable to adequately prevent disclosure of trade secrets and other proprietary information; Our patents may not provide meaningful or long-term protection for our technology, which could result in us losing some or all of our market position; Third parties have or may acquire patents that cover the materials, processes and technologies we use or may use in the future to manufacture our Amperium products, and our success depends on our ability to license such patents or other proprietary rights; There are a number of technological challenges that must be successfully addressed before our superconductor products can gain widespread commercial acceptance, and our inability to address such technological challenges could adversely affect our ability to acquire customers for our products; Our common stock has experienced, and may continue to experience, market price and volume fluctuations, which may prevent our stockholders from selling our common stock at a profit and could lead to costly litigation against us that could divert our management’s attention; Unfavorable results of legal proceedings could have a material adverse effect on our

business, operating results and financial condition and the other important factors discussed under the caption "Risk Factors" in Part 1.

AMSC Reports Q2 FY25 Results Page 8 Note: Non-GAAP net income is defined by the Company as net income before stock-based compensation; acquisition costs; amortization of acquisition-related intangibles; change in fair value of contingent consideration, other non-cash or unusual charges, and the tax effect of adjustments calculated at the relevant rate for our non-GAAP metric. The Company believes non-GAAP net income and non-GAAP net income per share assist management and investors in comparing the Company’s performance across reporting periods on a consistent basis by excluding these non-cash, non-recurring or other charges that it does not believe are indicative of its core operating performance. Actual GAAP and non-GAAP net income for the fiscal quarter ending December 31, 2025, including the above adjustments, may differ materially from those forecasted in the table above. Generally, a non-GAAP financial measure is a numerical measure of a company's performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP measure included in this release, however, should be considered in addition to, and not as a substitute for or superior to, net income or other measures of financial performance prepared in accordance with GAAP. A reconciliation of GAAP to non-GAAP net income is set forth in the table above.
