Diodes Slides; New Auto Chip Launch Puts Focus Back on Growth Track

Diodes Slides; New Auto Chip Launch Puts Focus Back on Growth Track

May 28, 2026

New York, May 28, 2026, 11:07 (EDT)

Diodes Incorporated shares slipped on Thursday, pulling back after a recent climb. Investors tracked the company’s new automotive-chip launch but kept focus on the ongoing cyclical rebound in analog and power semis. The stock was down 77 cents, or 0.7%, to $108.36 late Thursday morning. The Invesco QQQ Trust, a key Nasdaq tech gauge, was up 0.3%.

Diodes moved a day after it said it launched the APK43070Q, calling it an automotive-grade synchronous buck controller with a USB PD3.1 source controller for the higher-power USB-C charging standard. According to the company, the chip is aimed at single- and multi-port Type-C charging modules for cars, and handles charging ports up to 140W.

This doesn’t count as a revenue event. But it falls into the same themes pushing the stock: car makers using more electronics, signs of an industrial rebound, and AI-server power demand.

Diodes said this month that first-quarter revenue was up 22.1% to $405.5 million. GAAP earnings landed at 32 cents per share, while non-GAAP earnings came in at 43 cents. Non-GAAP strips out some costs and gains for what many investors see as a clearer take on operations, but it isn’t an official accounting figure.

Diodes president and CEO Gary Yu said on the earnings call that Q1 brought “solid demand recovery and momentum” in automotive, industrial and AI-server markets. Emily Yang, SVP of worldwide sales and marketing, told analysts that automotive revenue jumped over 32% year-on-year, with Europe showing better demand. SEC

The company said it expects second-quarter revenue to come in around $435 million, give or take 3%. GAAP gross margin is projected at 32.8%, plus or minus 1 point. Non-GAAP adjusted EPS is forecast at 60 cents, within a range of plus or minus 10 cents.

Peer moves split on Tuesday. Texas Instruments added 0.8%, ON Semiconductor dropped 1.6%, and Vishay Intertechnology picked up 4.7%. The mixed action left Diodes still lagging compared to today’s stronger names among analog and power chip stocks.

Diodes is in focus for investors again this week as the company’s schedule shows stops at the TD Cowen Technology, Media and Telecom Conference on Thursday, then Baird on June 2, Evercore on June 3, and Mizuho on June 9. Management is set for multiple updates on orders, pricing, and factory loading.

The risk is clear. A product launch won’t always bring orders, and Diodes in its latest 10-Q flagged tariffs, demand shifts in end markets, the cycles in semiconductors, competition, and price pressure as potential drags. The filing also showed weighted-average selling price slipped 6.9% in the first quarter from a year ago, with volume up 31.1%.

Where shares go next may have more to do with Diodes’ ability to hold margin as it moves from design wins to real orders, rather than the rollout of its new USB-C part. At this point, traders see a small drop, a new automotive chip, and a management team still insisting their recovery story can last.
