Analysis
Diodes reported record third quarter 2026 revenue of $532.6 million, up 35.8% from $392.2 million in the prior-year quarter and 19.5% from $445.5 million in the second quarter 2026. GAAP gross profit was $192.5 million, or 36.1% of revenue, compared with 30.7% a year earlier and 33.1% in the prior quarter. Non-GAAP gross margin was 36.2%. Management attributes the margin gain to product mix, price adjustments and improved capacity loading. Demand is described as broad: automotive revenue rose almost 60% year-over-year to a quarterly record, industrial rose 50%, and computing rose 33%, with AI servers, data center and enterprise storage cited as drivers. Global POS was a record and rose more than 30% year-over-year, while channel inventory fell below the company's normal range of 11 to 14 weeks.
Profitability moved sharply higher. GAAP net income was $43.7 million, or $0.95 per diluted share, compared with $14.3 million, or $0.31 per diluted share, a year earlier and $46.6 million, or $1, in the prior quarter. Non-GAAP adjusted net income was $54.5 million, or $1.18 per diluted share, against $17.2 million, or $0.37 per share a year earlier and $32.5 million, or $0.70 per share in the prior quarter. EBITDA was $89.7 million, or 16.8% of revenue, compared with $46.6 million, or 11.9%, a year earlier. GAAP operating expenses were $129.1 million, or 24.2% of revenue, against $114.3 million in the prior quarter. The filing gives no operating income line, so the operating result cannot be read directly from the document.
Cash generation and the balance sheet changed in the quarter. Operating cash flow was $97.2 million and free cash flow was $43.9 million after $53.2 million of capital expenditures, which the CFO said were 10% of revenue, above the company's 5% to 9% target range, with year-to-date capex at 8.6%. The company issued $375 million of 0% convertible senior notes due 2031, netting $342.9 million, and used $35 million of the proceeds to repurchase 360,119 shares in a privately negotiated transaction. Total debt was approximately $405 million, cash and short-term investments approximately $578 million, and working capital approximately $1.1 billion. Inventory rose $30.5 million to $535 million, of which $29.5 million was added through the ElevATE Semiconductor acquisition. Total inventory days fell 11 days to approximately 141.
The fourth quarter guide is for revenue of approximately $550 million, plus or minus 3%, which the CFO said represents a 40.4% increase year-over-year and a 3.2% increase sequentially at the midpoint. Non-GAAP gross margin is guided to 37% plus or minus 1% and non-GAAP adjusted EPS to $1.35 plus or minus $0.10. The CEO said full year 2026 revenue is expected to rise approximately 30% over 2025 at the midpoint. The SVP Sales said the fourth quarter guide assumes growth of more than 3%, compared with the company's usual 5% to 6% decline in that quarter, and attributed this to backlog and design pipeline visibility. The company also said notebook and PC softness is expected to be offset by AI server, data center and enterprise storage demand.
The figures that deserve most attention are the gap between GAAP and non-GAAP earnings in the quarter, the capex level above the stated target range, the inventory build and the Q4 sequential assumption. The filing states that non-GAAP results excluded $7.9 million net of tax of unrealized loss on investments, $4.2 million of acquisition intangible amortization, $3 million gain on disposal of subsidiary, $1.4 million of acquisition costs and $0.3 million of acquisition related inventory amortization. The company also states that non-cash share-based compensation of $7.4 million net of tax would reduce both GAAP and non-GAAP per-share earnings by $0.16 if included. The document contains no press release, no prior-period outlook and no share price reaction, so this read compares only the figures printed in the transcript.
