Earnings and Revenue Trajectory
AI Review
The company's recent earnings show an abrupt turnaround from a painful cyclical downturn into an aggressive order rebound. Fiscal 2026 revenue dropped fifteen percent to fifty million dollars, resulting in an operating loss of fourteen million dollars as older electric-vehicle silicon carbide orders evaporated. However, the fourth quarter rebounded sharply to nearly nineteen million dollars as shipments began for new artificial intelligence and optical networking customers. This dramatic recovery is driven by an effective order backlog reaching one hundred million dollars, supporting management guidance for fiscal 2027 revenue between one hundred thirty and one hundred fifty million dollars. While this incoming wave ensures near-term sales acceleration, profits remain vulnerable to delivery timing and customer concentration.

Profitability & Margins
Margins and Operating Efficiency
AI Review
Profit margins have experienced severe swings due to changing factory production volumes. Gross margin tumbled from forty-nine percent in fiscal 2024 to thirty-five percent in fiscal 2026, pushing operating margins down to negative twenty-eight percent. This margin decay occurred because fixed factory overhead and rising research expenses could not be covered by falling legacy revenues. Profitability should rebound strongly toward twenty percent operating margins as high-volume systems and proprietary replacement contactors ship throughout fiscal 2027. Yet this margin recovery is cyclical rather than permanent. Whenever lead customers pause tooling purchases between chip generations, lower factory throughput will quickly squeeze profit margins back down toward breakeven levels.
