SEC filingRevenue growth driven by industrial end-market sales; gross margin stable at 55% despite operating expense surge from CEO retirement costs.
For the three months ended September 30, 2025, Power Integrations reported net revenues of $118.9 million, a 2.7% increase from $115.8 million in the same period of 2024. The growth was primarily driven by higher sales in the industrial end-market. Gross profit rose to $64.9 million from $63.2 million, with gross margin remaining flat at 54.5% for both periods. For the nine-month period, net revenues increased 8.5% to $340.3 million from $313.7 million, and gross margin improved to 55.0% from 53.4%, attributed to favorable end-market mix with a greater proportion of revenues from higher-margin end-markets.
Total operating expenses surged to $68.8 million in Q3 2025 from $51.6 million in Q3 2024, a 33.3% increase. This was primarily due to higher stock-based compensation expense from an award modification associated with the retirement of the former CEO ($13.6 million) and expenses related to an employee litigation matter ($0.7 million). Research and development expenses increased to $26.7 million from $25.8 million, sales and marketing to $17.5 million from $17.1 million, and general and administrative to $10.4 million from $8.6 million. As a result, the company reported an operating loss of $3.9 million (negative 3.3% operating margin) compared to operating income of $11.5 million (9.9% margin) in the prior year. Net loss was $1.4 million versus net income of $14.2 million in Q3 2024.
The industrial end-market was the standout performer, with revenue mix increasing to 42% in Q3 2025 from 36% in Q3 2024, reflecting strong demand. Consumer declined to 34% from 38%, Computer to 13% from 14%, and Communications to 11% from 12%. The shift toward industrial, which carries higher margins, was cited as the primary driver of the nine-month gross margin improvement. International sales remained dominant at 98% of net revenues, with Asia representing approximately 83% of sales. Sales to distributors accounted for 69% of net revenues. Customer concentration remained high, with Avnet representing 34% of Q3 2025 revenues and Salcomp Group 11%.
Management did not provide specific forward guidance in the MD&A. However, the company highlighted its growth strategy focused on expanding its served available market (SAM) to approximately $4 billion through new product introductions (e.g., BridgeSwitch-2 motor-driver ICs, GaN-based products for EVs and data centers) and increasing penetration of existing markets. The company noted that its quarterly operating results are difficult to predict and subject to significant fluctuations due to supply-chain dynamics, macroeconomic conditions, and trade policy uncertainties. The board raised the quarterly cash dividend to $0.215 per share for 2026, signaling confidence in cash generation. The company believes existing liquidity and cash from operations will satisfy working capital needs for at least the next 12 months.
As of September 30, 2025, Power Integrations maintained a strong liquidity position with cash and cash equivalents of $48.6M and short-term marketable securities of $193.2M, totaling $241.9M. The company has no outstanding debt, as total liabilities of $100.6M consist primarily of accounts payable and accrued expenses. Stockholders' equity stood at $672.0M, down from $749.8M at year-end 2024 due to share repurchases and dividends. Inventory of $164.6M was relatively flat compared to $165.6M at December 31, 2024, with raw materials comprising the largest component at $100.7M.
The Notes disclose wafer-supply agreements with Seiko Epson and ROHM Lapis Semiconductor, which include mutual sharing of yen/dollar exchange rate fluctuations on future purchases. However, no specific dollar commitments or capacity reservation amounts are provided. The company also has standard indemnification obligations under distributor sales agreements, but no material claims were outstanding as of September 30, 2025.
Power Integrations aggressively returned capital to shareholders in the first nine months of 2025. The company repurchased 2.0 million shares for $98.1 million, fully utilizing its existing $48.1M authorization and a newly authorized $50.0M program in April 2025. As a result, there was no remaining repurchase authority. Dividends totaled $35.6M, an increase from $34.1M in the prior-year period, with the quarterly dividend raised from $0.20 to $0.21 per share. Capital expenditures for property and equipment were $17.3M, reflecting ongoing investment in manufacturing and facilities.
Power Integrations operates as a single reportable segment. Geographic revenue disclosures show broad diversification, with Hong Kong/China as the largest region at $192.6M (57% of total net revenues of $340.3M) for the nine months ended September 30, 2025. Other significant regions include Korea ($30.3M), Taiwan ($20.0M), and Germany ($20.2M). The Americas contributed $17.7M. Sales to distributors accounted for $238.7M, or approximately 70% of total revenue, with Avnet representing 33% and the Salcomp Group 10% of net revenues.
Operating cash flow of $85.3M significantly exceeded net income of $8.8M, reflecting strong cash conversion driven by non-cash charges (depreciation, amortization, stock-based compensation) and favorable working capital changes. The primary working capital tailwinds came from increases in accounts payable ($6.0M) and taxes/accrued liabilities ($9.2M), partially offset by a rise in accounts receivable ($4.0M).
Capital expenditure intensity (capex/CFO) was 20.3%, up from 21.4% in the prior period, indicating moderate reinvestment. Free cash flow (CFO minus capex) was approximately $68.0M, comfortably covering dividends of $35.6M but falling short of total capital returns ($133.7M) due to the large share repurchase program. The company funded the shortfall by drawing $13.0M on its line of credit (subsequently repaid) and by generating $40.7M from investing activities (net sales of marketable securities).
Anomalies: The $98.1M in share repurchases was nearly four times the prior-year level, a significant increase in capital allocation. The company also recorded a $13.0M draw and repayment on its line of credit, suggesting temporary liquidity management.
