AMSC turned a corner in the first quarter of fiscal 2026 that the equity had been waiting on for years. The Devens, Massachusetts power-electronics and grid-systems vendor printed $94.1 million in revenue for the three months ended June 30, 2026, a 30 percent year-over-year jump, with a $130 million-plus orders intake that pushed the rolling twelve-month backlog above $300 million for the first time. Net income under generally accepted accounting principles, the standard set of accounting rules companies use when reporting to the SEC, came in at $9.5 million, or $0.21 a share, with operating cash flow of $16 million, nearly four times the year-ago quarter. The headline number, however, is that a company which had been a perennial cash burner and small-cap power-electronics stock has just completed a Brazilian transformer acquisition and is now generating record revenue against a confirmed $153 million cash balance.
The thesis is that AMSC is no longer a niche superconductivity story; it is becoming a power-grid consolidator assembled piece by piece through acquisition, with the December 2025 purchase of Brazilian transformer manufacturer Comtrafo Indústria de Transformadores Elétricos S.A. now contributing real revenue and depressing gross margin temporarily through purchase-accounting charges. The market is pricing AMSC for a compressed-utility-component multiple on a $300 million revenue run-rate, with management guiding to a second-quarter revenue floor of $85 million and a target of gross margin improvement in the second half of the fiscal year. The mechanism for the equity re-rating, in our view, is the convergence of (a) the Comtrafo acquisition washing through the income statement, (b) the Step 1 of the mining-utility order wave converting to recognized revenue, and (c) the deferred-revenue balance of $102.6 million acting as a working capital tailwind that suggests revenue is being underwritten by deposits rather than by accounts-receivable stretch. The price-to-sales multiple on consensus fiscal 2027 revenue is now a meaningful discount to diversified power-electronics peers, in our reading, even after a re-rating from the mid-single-digit sales multiple at the start of fiscal 2026.
The single load-bearing risk is the gross-margin compression visible in the quarter: 26 percent for the three months ended June 30, 2026, down from 34 percent a year earlier, driven by a less favorable product mix, $0.7 million of Comtrafo purchase-accounting inventory step-up (the process of marking acquired inventory up to its fair value at the deal close, with the markup flowing through cost of goods sold as the inventory is sold), $0.5 million of acquired-backlog intangible amortization, and Brazilian Real translation drag. A second load-bearing risk is the concentration in the Wind segment's single largest customer, identified in the annual report as a meaningful share of revenue, which means the 45 percent year-over-year Wind segment growth is structurally dependent on a small number of ship-and-license wins. The next data point that tests the thesis is the second-quarter fiscal 2026 print for the period ending September 30, 2026, which management has guided to exceed $85 million in revenue and $1 million in GAAP net income, with non-GAAP net income, a profitability measure that excludes stock-based compensation, intangible amortization, and changes in the fair value of acquisition-related contingent consideration, expected to exceed $8 million, or $0.17 a share.
