Wind$17.8M+45% YoY

Largest Expense Items

Cost of revenues$69.3M+45% YoY

Gross margin decline driven by less favorable product mix and Comtrafo purchase accounting items

Selling, general and administrative$18.6M+31% YoY

Driven primarily by addition of Comtrafo expenses, higher compensation, and additional stock-based compensation

Research and development$3.9M-9% YoY

Driven primarily by lower stock-based compensation expense and lower outside services expense

Margins: Gross margin fell to 26% from 34% YoY due to less favorable product mix and Comtrafo purchase accounting items (inventory step-up and backlog amortization); operating income was also boosted by an $8.1M non-cash gain on contingent consideration revaluation.

Watch Items from the Filing

Grid segment swung to an operating loss of $2.2M from operating income of $4.2M a year ago, due to lower gross margins and Comtrafo purchase accounting expense.
Company disclosed a material weakness in internal controls over Comtrafo purchase accounting and fair value accounting, not yet remediated as of June 30, 2026.
Inox Wind Limited represented 19% of total revenue in the quarter (21% a year ago); filing notes a significant portion of Wind segment revenue depends on a single customer.
Comtrafo earnout contingent consideration liability of $31.9M remains outstanding, tied to EBITDA targets through 2028; fair value swings ($8.1M gain this quarter) will continue to affect reported net income.
