AI Analysis

AI-generated, general educational analysis — not personal investment advice.

Power Integrations is a small, focused semiconductor company - 877 employees - making analog and mixed-signal chips for high-voltage power conversion. Its niche in power supplies for appliances, meters, lighting and consumer devices may create some stickiness, but the numbers do not yet show a wide moat. The balance sheet is a real strength: debt-to-equity of 0.03, Altman Z-Score of 17.90, and Piotroski F-Score of 7/9, all FairStock calculations. Earnings, however, are cyclical and uneven. In fiscal year 2023 (period ended 2023-12-31), net income was $55.7M on revenue of $444.5M; in fiscal year 2024 (period ended 2024-12-31), net income fell to $32.2M on $419.0M; in fiscal year 2025 (period ended 2025-12-31), net income was $22.1M on $443.5M. In fiscal Q3 2025, the quarter ended 2025-09-30, it lost $1.4M, then in fiscal Q2 2026, the quarter ended 2026-06-30, it earned $9.8M on revenue of $118.9M. That is an improvement, but at the 2026-10-13 close, FairStock's P/E is 106.14 and EV/EBITDA is 53.21. The Graham Number is $10.99 against a $46.70 price - a margin of safety of -324.93%. ROE is 3.62%, ROCE is 2.62%, and FCF yield is only 3.0%. The Lynch category is cyclical semiconductors. I see a decent balance sheet and a possible cyclical recovery, but the price already discounts a lot of it.

In plain English: Power Integrations makes small chips that help control and convert electric power in chargers, appliances, lighting and similar products. The company is profitable and carries very little debt, but profits have been thin and uneven lately. Compared with its recent earnings and net assets, the shares look expensive rather than cheap.
