Key Financial Metrics

Material Changes vs. Prior Period

• Revenue: Q3 revenue decreased slightly by 0.5% ($0.8M) year-over-year. The nine-month revenue decreased by 2.1% ($11.1M). The decline was driven by lower sales in Power ICs and the completion of a $45M license and development services agreement in the prior year, partially offset by growth in Power Discrete products and packaging services.
• Profitability: Gross margin compressed to 21.1% in Q3 (down 30 bps) and 22.1% for the nine months (down 90 bps) due to higher material costs and lower unit shipments. Operating loss widened to $14.1M in Q3 from $10.7M in the prior year, primarily due to increased R&D expenses ($26.1M vs $23.4M) driven by higher compensation and prototyping costs.
• Debt Reduction: Total debt decreased significantly. The company paid off a $45M term loan in August 2025 and terminated an accounts receivable factoring agreement. As of March 31, 2026, total debt stood at approximately $4.4M, compared to $26.7M in the prior year.
• Joint Venture (JV) Sale: The company sold approximately 20.3% of its equity interest in its Chongqing JV for $150M. Proceeds of $133.5M were received during the nine-month period, significantly boosting investing cash flows. The company retained an 18.9% interest and continues to account for the investment using the equity method.

Guidance, Outlook, and Risks

• Outlook: Management expects average selling prices to continue to erode, a typical industry trend, and plans to offset this through new product introductions and cost reductions. The company is diversifying beyond the PC market into consumer, communication, and industrial segments.
• Share Repurchases: In November 2025, the Board approved a $30M share repurchase program. As of March 31, 2026, the company had repurchased approximately $18.2M of shares, with $11.9M remaining available.
• Risks:
  • JV Transaction Completion: The final installment of the JV sale ($15.6M) is subject to closing conditions outside the company's control. Failure to meet these could require unwinding the transaction.
  • Customer Concentration: Two customers (Customer A and Customer B) accounted for approximately 70.8% of Q3 revenue and 73.4% of accounts receivable.
  • Market Conditions: Revenue remains sensitive to global economic conditions and the health of the PC market, which has seen modest declines.
  • Tax Legislation: The "One Big Beautiful Bill Act" (OBBB) enacted in July 2025 introduced changes to federal tax provisions, though management deemed the impact immaterial for the current quarter.

Investor Verification Checklist

• JV Sale Finalization: Verify the status of the remaining $15.6M installment payment and the satisfaction of closing conditions for the Chongqing JV equity sale.
• Customer Concentration: Monitor the stability of revenue from the top two customers, which represent over 70% of sales.
• Margin Pressure: Assess the company's ability to maintain gross margins amidst rising material costs and industry-wide price erosion.
• Share Repurchase Activity: Track the utilization of the remaining $11.9M repurchase authorization and its impact on share count.
• Operating Cash Flow: Review the trend in operating cash flows, which turned negative ($6.3M used) for the nine months ended March 31, 2026, compared to positive cash flow in the prior year.
