Diodes Posts Record Revenue but Trades at Steep Discount
NEW YORK, November 6 —
Diodes Incorporated (DIOD) broke every quarterly revenue record last quarter, then guided the fourth quarter above its own seasonal norms, yet the stock trades at 12.3x forward earnings. The $142.50 analyst consensus target implies the market is either too fearful of an August financing event or simply has not updated for a business growing at 35.8%.
- Q3 revenue $532.6M, a quarterly record; gross margin 36.1%, up more than 500 basis points year-over-year.
- Q4 guidance of approximately $550M implies 3.2% sequential growth versus a historical seasonal decline of 5-6%.
- Stock at $68.36, 12.3x forward earnings, against $142.50 analyst target; short interest 9.4% of float.
Automotive and AI Are Doing the Lifting
Diodes Incorporated is a Plano, Texas semiconductor company selling MOSFETs, Schottky diodes, power management ICs, and motor drivers across automotive, industrial, computing, consumer, and communications markets. In Q3, the automotive segment reached a quarterly record, up roughly 60% year-over-year and 26% sequentially, driven by vehicle content expansion and market share gains. Industrial followed an identical sequential trajectory, with AI infrastructure, automation, and energy applications as the demand drivers. Together those two segments represented 46% of product revenue. Computing also hit a record on AI-server demand. The 36.1% gross margin shows what happens when three high-value end-markets accelerate simultaneously: pricing power compounds with utilization gains.
The August Filing Is the Discount's Alibi
In August 2026, Diodes filed an 8-K disclosing entry into a Material Definitive Agreement, creation of a Material Direct Financial Obligation, and Unregistered Sales of Equity Securities. The combination of new debt and unregistered equity tends to rattle holders, adding debt service risk and signaling potential dilution. That filing appears to anchor short interest at 9.4% of float, implying conviction rather than routine hedging. Against three consecutive EPS beats and $43.9 million in Q3 free cash flow, the balance sheet risk looks priced in rather than emerging. Plugging the numbers into a DCF calculator at any reasonable growth assumption produces a valuation well above $68.36.

The Fourth Quarter Is Already Rewriting the Script
Diodes guided Q4 to approximately $550 million, implying 40.4% year-over-year growth. The more instructive figure is sequential: a 3.2% gain against a historical norm of 5-6% decline, per SVP of worldwide sales Emily Yang. Record global point-of-sale, up more than 30% year-over-year, and channel inventory running below normal both confirm demand is durable, not pulled forward. The thesis breaks on a gross margin miss against the 37% Q4 guide; sustained expansion above that level would close the valuation gap independent of any multiple re-rating. At 12.3x forward earnings, the valuation leaves room for the numbers to keep winning. Run the free Diodes Incorporated deep-dive →
