Changes in Brazil' s or India' s political, social, regulatory and economic environment may affect our financial performance; Industry consolidation could result in more powerful competitors and fewer customers; Evolving and varied expectations 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; 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; 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. Item 1A of our Form 10-K for the fiscal year ended March 31, 2026, and our other reports filed with the SEC. These important factors, among others, could cause actual results to differ materially from those indicated by forward-looking statements made herein and presented elsewhere by management from time to time. Any such forward-looking statements represent management's estimates as of the date of this Quarterly Report on Form 10-Q. While we may elect to update such forward-looking statements at some point in the future, we disclaim any obligation to do so, even if subsequent events cause our views to change.

Executive Overview Guided by a belief in the power of next, we are a leading provider of power control solutions that apply innovation and creativity to address today’s challenges and enable a more resilient and sustainable energy future. Driven by our purpose “to power progress,” we integrate future-facing technologies to balance the growing global demand for power with the need for reliable, and efficient power delivery. Our advanced grid systems, engineering services, power electronics, software controls, and superconductor-based solutions help the traditional and renewable energy sectors, electric utilities, the materials and mining sector, industrial facilities, and other critical infrastructure operators optimize network reliability, improve power quality, alleviate grid constraints, and scale operations without added complexity or size. We also deliver ship protection and power management solutions that enhance fleet efficiency, survivability, and operational readiness for the U.S. Navy and allied fleets. In the wind power market, we provide advanced electrical control systems, engineering, and support services that help manufacturers lower the cost of wind energy and improve turbine performance. Beyond these markets, we provide industrial process, environmental and emission control capabilities that support operational efficiency across the broader energy infrastructure. Across our businesses, our solutions are helping optimize power networks, strengthen naval capabilities, and support gigawatts of renewable energy generation worldwide as governments and industries continue investing in more resilient, secure, and sustainable power systems. We operate our business under two market-facing business segments: Grid and Wind. We believe this market centric structure enables us to more effectively anticipate and meet the needs of power generators, power utilities, industrial manufacturers, the military and renewable energy companies. • Grid. Our Grid business segment enables electric utilities, industrial facilities, and traditional and renewable energy project developers to connect, transmit, transform and distribute power with exceptional efficiency, reliability, security and affordability. We provide transmission planning services that allow us to identify power grid congestion, poor power quality, and other risks, which help us determine how our solutions can improve network performance. These services often lead to sales of our grid interconnection solutions for wind farms and solar power plants, power quality systems and transmission and distribution cable systems. We also sell critical shipyard infrastructure power solutions, ship power supplies and ship protection products to U.S. and allied Navies through our Grid business segment. • Wind. Our Wind business segment enables manufacturers to field wind turbines with exceptional power output, reliability and affordability. We supply advanced power electronics and control systems, license our highly engineered wind turbine designs, and provide extensive customer support services to wind turbine manufacturers. Our design portfolio includes a broad range of drivetrains and power ratings of 2 megawatts ("MWs") and higher. We provide a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility. Our fiscal year begins on April 1 and ends on March 31. When we refer to a particular fiscal year, we are referring to the fiscal year that began on April 1 of that same year. For example, fiscal 2026 refers to the fiscal year that began on April 1, 2026. Other fiscal years follow similarly. 29 Changes in macroeconomic conditions arising from various reasons, such as the ongoing wars between Russia and Ukraine, and in the Middle East, tariffs, trade restrictions and resulting trade conflicts, labor force availability, sourcing, material delays and global supply chain disruptions, could have a material adverse effect on our business, financial condition and results of operations. On December 5, 2025 (the "Comtrafo Acquisition Date"), we entered into a Stock Exchange Agreement (the "Stock Exchange Agreement") with the selling stockholders named therein (the "Stockholders"). Pursuant to the terms of the Stock Exchange Agreement, Mardin Participações Ltda., an entity incorporated in Brazil (“AMSC Brazil”) and our wholly-owned subsidiary, directly or indirectly, purchased all of the issued and outstanding shares of Comtrafo Indústria de Transformadores Elétricos S.A. ("Comtrafo") (collectively, the "Comtrafo Acquisition") for (a) (i) 300 million Brazilian Real in cash; and (b) 2,417,142 restricted shares of our common stock, $0.01 par value per share (the "AMSC Shares") that were paid and issued, respectively, at closing. In addition, pursuant to certain additional real property agreements, AMSC Brazil through Comtrafo purchased certain real estate assets and transportation assets of Comtrafo for 155.6 million Brazilian Real and 13.4 million Brazilian Real, respectively, in cash. Additionally, AMSC Brazil has agreed to pay the Stockholders up to an additional 382.5 million Brazilian Real in cash (the "Earnout") upon the achievement of specified earnings before interest, taxes, depreciation, and amortization ("EBITDA") objectives during the three years following the closing. Comtrafo is a Brazil-based manufacturer of large power and distribution transformers primarily for utility customers and also for industrial customers. In June 2025, we completed an offering of 4,743,750 shares of our common stock at a public offering price of $28.00 per share under our Registration Statement on Form S-3. We received aggregate net proceeds of approximately $124.6 million after deducting underwriting discounts and commissions and offering expenses. Critical Accounting Policies and Estimates The preparation of the unaudited condensed consolidated financial statements requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ under different assumptions or conditions. Results of Operations Three months ended June 30, 2026, compared to the three months ended June 30, 2025 Revenues Total revenues increased 30% to $94.1 million for the three months ended June 30, 2026 compared to $72.4 million for the three months ended June 30, 2025. Our revenues are summarized as follows (in thousands): Three Months Ended June 30, 2026 2025 Revenues: Grid $ 76,323 $ 60,087 Wind 17,750 12,271 Total $ 94,073 $ 72,358 Our Grid business segment accounted for 81% of total revenues for the three months ended June 30, 2026 compared to 83% for the three months ended June 30, 2025. Our Grid business segment revenues increased 27% to $76.3 million in the three months ended June 30, 2026, from $60.1 million in the three months ended June 30, 2025. The increase in the Grid business segment revenues in the three months ended June 30, 2026, compared to the three months ended June 30, 2025, was driven by the addition of Comtrafo revenues. 30 Our Wind business segment accounted for 19% of total revenues for the three months ended June 30, 2026, compared to 17% for the three months ended June 30, 2025. Revenues in the Wind business segment increased 45% to $17.8 million in the three months ended June 30, 2026, from $12.3 million in the three months ended June 30, 2025. The increase during the three months ended June 30, 2026, compared to the three months ended June 30, 2025, was driven by additional shipments of electrical control systems ("ECS"). Cost of Revenues and Gross Margin Cost of revenues increased by 45% to $69.3 million for the three months ended June 30, 2026, compared to $47.9 million for the three months ended June 30, 2025. Gross margin was 26% for the three months ended June 30, 2026, compared to 34% for the three months ended June 30, 2025. Cost of revenues includes total amortization expense of $0.5 million in the three months ended June 30, 2026 as a result of Comtrafo acquired backlog intangible assets. In addition, $0.7 million related to a fair value adjustment for the step-up basis assigned to acquired inventory to properly reflect the fair value in purchase accounting was charged to cost of revenues in the three months ended June 30, 2026. The decrease in gross margin in the three months ended June 30, 2026 was due to a less favorable product mix and the impact of Comtrafo purchase accounting items. Operating Expenses Research and development Research and development ("R&D") expenses decreased 9% in the three months ended June 30, 2026, to $3.9 million from $4.3 million in the three months ended June 30, 2025. The decrease in the three months ended June 30, 2026 was driven primarily by lower stock-based compensation expense and lower outside services expense. Selling, general, and administrative Selling, general and administrative ("SG&A") expenses increased 31% in the three months ended June 30, 2026, to $18.6 million from $14.2 million in the three months ended June 30, 2025. The increase in SG&A expense in the three months ended June 30, 2026 was driven primarily by the addition of Comtrafo expenses, higher overall compensation expense, and additional stock-based compensation expense. Amortization of acquisition-related intangibles We recorded amortization expense related to our core technology and know-how and customer relationships of $0.5 million in the three months ended June 30, 2026, and $0.3 million in the three months ended June 30, 2025. The increase in amortization expense in the three months ended June 30, 2026, was a result of additional amortization related to the Comtrafo acquisition, as well as ongoing activity from NEPSI and Neeltran which are using the economic consumption method as the basis to amortize the acquired customer relationships intangible assets. Change in fair value of contingent consideration The change in fair value of our contingent consideration for the earnout payment on the acquisition of Comtrafo resulted in a gain of $8.1 million from a decrease in fair value of the contingent consideration driven by changes in the forecast in the three months ended June 30, 2026. There was no activity in the three months ended June 30, 2025 related to the change in fair value of contingent consideration. 31 Operating income (loss) Our operating income (loss) is summarized as follows (in thousands): Three Months Ended June 30, 2026 2025 Operating income: Grid $ (2,166 ) $ 4,155 Wind 3,883 1,489 Unallocated corporate expenses 8,115 — Total $ 9,832 $ 5,644 Our Grid business segment generated operating loss of $2.2 million in the three months ended June 30, 2026, compared to an operating income of $4.2 million in the three months ended June 30, 2025. The decrease in the Grid business segment operating income in the three months ended June 30, 2026 was due to lower gross margins and Comtrafo purchase accounting expense. Our Wind business segment generated operating income of $3.9 million in the three months ended June 30, 2026, compared to operating income of $1.5 million in the three months ended June 30, 2025. The increase in the Wind business segment operating income in the three months ended June 30, 2026 was due to higher revenues and gross margins from increased sales of ECS units. Interest income, net Interest income, net, was $1.5 million in the three months ended June 30, 2026, compared to $0.9 million in the three months ended June 30, 2025. The increase in interest income, net, in the three months ended June 30, 2026 was due to higher cash balances in the current year. Other income (expense), net Other expense, net, was $0.6 million in the three months ended June 30, 2026, compared to other income, net of $0.3 million in the three months ended June 30, 2025. The decrease in other income, net, during the three months ended June 30, 2026, was driven by unfavorable fluctuations in foreign currencies. Income Taxes Income tax expense was $1.3 million in the three months ended June 30, 2026, compared to income tax expense of $0.2 million in the three months ended June 30, 2025. The increase in our income tax expense was primarily due to taxes in foreign jurisdictions. 32 Net income Net income was $9.5 million in the three months ended June 30, 2026, compared to $6.7 million in the three months ended June 30, 2025. The increase in net income for the three months ended June 30, 2026 was driven primarily by the change in fair value of contingent consideration. Non-GAAP Financial Measure - Non-GAAP Net Income 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 measures included in this Quarterly Report on Form 10-Q, however, should be considered in addition to, and not as a substitute for or superior to the comparable measures prepared in accordance with GAAP. We define non-GAAP net income as net income before stock-based compensation, amortization of acquisition-related intangibles, change in fair value of contingent consideration, and other non-cash or unusual charges. We believe non-GAAP net income assists management and investors in comparing our performance across reporting periods on a consistent basis by excluding these non-cash charges and other items that we do not believe are indicative of our core operating performance. In addition, we use non-GAAP net income as a factor to evaluate the effectiveness of our business strategies. A reconciliation of GAAP to non-GAAP net income is set forth in the table below (in thousands, except per share data): Three Months Ended June 30, 2026 2025 Net income $ 9,490 $ 6,724 Stock-based compensation 5,264 4,526 Amortization of acquisition-related intangibles 976 337 Change in fair value of contingent consideration (8,115 ) — Non-GAAP net income $ 7,615 $ 11,587 Non-GAAP net income per share - basic $ 0.17 $ 0.30 Non-GAAP net income per share - diluted $ 0.16 $ 0.29 Weighted average shares outstanding - basic 45,995 38,875 Weighted average shares outstanding - diluted 47,124 39,742 We generated non-GAAP net income of $7.6 million, or $0.17 per share, for the three months ended June 30, 2026, compared to a non-GAAP net income of $11.6 million, or $0.30 per share, for the three months ended June 30, 2025. For the three months ended June 30, 2026, the decrease in non-GAAP net income was a result of lower gross margins. 33 Liquidity and Capital Resources The Company’s primary sources of liquidity are internally generated cash provided by operating activities, our cash and cash equivalents on hand, along with access to capital markets, including through our currently effective Registration Statements on Form S-3. We believe that these sources of liquidity are sufficient to meet both our short-term and reasonably foreseeable long-term requirements and obligations. As of June 30, 2026, we had cash, cash equivalents and restricted cash of $153.1 million, compared to $147.6 million as of March 31, 2026, an increase of $5.5 million. As of June 30, 2026, we had $22.8 million in cash, cash equivalents, and restricted cash in foreign bank accounts. Our cash, cash equivalents, and restricted cash are summarized as follows (in thousands): June 30, 2026 March 31, 2026 Cash and cash equivalents $ 143,707 $ 140,693 Restricted cash 9,406 6,860 Total cash, cash equivalents, and restricted cash $ 153,113 $ 147,553 For the three months ended June 30, 2026, net cash provided by operating activities was $16.0 million, compared to $4.1 million for the three months ended June 30, 2025. The increase in cash flows provided by operating activities in the three months ended June 30, 2026 was due primarily to changes in deferred revenue, inventory, prepaid expenses and other current assets, and changes in fair value consideration. For the three months ended June 30, 2026, net cash used in investing activities was $10.5 million, compared to $0.7 million for the three months ended June 30, 2025. The increase in net cash used in investing activities was primarily due to cash paid for the purchase of property, plant and equipment in the current year. For the three months ended June 30, 2026, there was no cash provided by or used in financing activities. For the three months ended June 30, 2025, net cash provided by financing activities was $124.6 million. The decrease in net cash provided by financing activities was due primarily to the equity raise in June 2025. As of June 30, 2026, we had $5.6 million of restricted cash included in long-term assets and $3.8 million of restricted cash included in current assets. At March 31, 2026, we had $3.3 million of restricted cash included in long-term assets and $3.5 million of restricted cash in current assets. These amounts included in restricted cash primarily represent collateral deposits to secure surety bonds and letters of credit for various customer contracts. These deposits are held in interest bearing accounts. We are a party to many contractual obligations involving commitments to make payments to third parties. These obligations impact our short-term and long-term liquidity and capital resource needs. Certain contractual obligations are reflected on the condensed consolidated balance sheet as of June 30, 2026, while others are considered future commitments. We have various contractual arrangements, under which we have committed to purchase certain minimum quantities of goods or services on an annual basis. For information regarding our other contractual obligations, refer to Note 3, "Revenue Recognition," Note 14, "Contingent Consideration," Note 15, "Leases" and Note 16, "Commitments and Contingencies" to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. Other than the contingent consideration owed to the former Comtrafo stockholders there have been no material changes to our contractual obligations from those disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2026. 34 We believe we have sufficient available liquidity to fund our operations and capital expenditures for at least the next twelve months and into the future. We raised $124.6 million, net of offering expenses, through an equity raise in June 2025, of which $88.3 million was used for the Comtrafo Acquisition. In addition, we may seek to raise additional capital, which could be in the form of loans, convertible debt or equity, to fund our operating requirements and capital expenditures. There can be no assurance that we will be able to raise additional capital on favorable terms or at all or execute on any other means of improving our liquidity as described above. Additionally, the impact of global sources of instability, including the ongoing war between Russia and Ukraine, tariffs, trade restrictions and resulting trade conflicts, instability of financial institutions and political instability in the United States, on the global financial markets may reduce our ability to raise additional capital, if necessary, which could negatively impact our liquidity. Legal Proceedings From time to time, we are involved in legal and administrative proceedings and claims of various types. We record a liability in our condensed consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. We review these estimates each accounting period as additional information is known and adjust the loss provision when appropriate. If a matter is both probable to result in liability and the amounts of loss can be reasonably estimated, we estimate and disclose the possible loss or range of loss to the extent necessary to make the condensed consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in our condensed consolidated financial statements. Recent Accounting Pronouncements In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures. The amendments in ASU 2024-03 address investor requests for more disclosure of disaggregated financial reporting information about expenses presented in the income statement. Following the release of ASU 2024-03 in November 2024, the effective date will be annual reporting periods beginning after December 15, 2026. We are evaluating the impact on our consolidated financial statements. In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software. The amendments in ASU 2025-06 remove all references to software development project stages and requires entities to start capitalizing software costs when both of the following occur: (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. Following the release of ASU 2024-05 in September 2025, the effective date will be annual reporting periods beginning after December 15, 2027. We are evaluating the impact on our consolidated financial statements. We do not believe that, outside of those disclosed here, there are any other recently issued accounting pronouncements that will have a material impact on our condensed consolidated financial statements. 35
