Three months ago, Diodes told investors it was no longer merely recovering but managing very strong demand and adding capacity. The stock has since fallen about 11% while the S&P 500 barely moved. That disconnect frames the third-quarter report due after the close on November 5: either the company delivers the step change it promised and the market reprices, or the selloff turns out to have been an early read on an upturn running ahead of itself.
The bar is clear and set high. Management guided to non-GAAP earnings of $0.95 to $1.15 per share on revenue of $494.7 million to $525.3 million. When that outlook arrived, analysts were at $0.83, so the Street has moved up to $1.05, the exact midpoint. That figure would nearly triple the $0.37 earned a year ago, roughly 184% growth, and add about 50% to last quarter's $0.70. The revenue midpoint of about $510 million implies a 14.5% sequential gain from $445.5 million and roughly 30% growth from the $392.2 million of a year ago. Hitting the midpoint only keeps the story intact. Moving the stock likely requires the upper half of the range and a confident fourth-quarter outlook.
The progression of guidance is what makes this quarter a real test. Entering 2026, management guided the first quarter up only about 1% sequentially and called that better than seasonal. By midyear, the forecast had shifted to double-digit sequential growth across nearly every end market. Computing drives much of that, having grown 18% sequentially and 33% year over year last quarter as new timing and clock products ramp into AI server platforms. Industrial grew 5% sequentially, and management said excess inventory was behind it. Automotive keeps gaining share, with content per vehicle climbing steadily. Validation looks like computing growing again on top of that big second-quarter jump, plus clear signs that the industrial recovery is about real restocking demand rather than a one-quarter bounce.
The main swing factor is supply, not demand. Management flagged pockets of capacity constraints that could limit shipments, at a time when it is also moving production from 6-inch to 8-inch wafers. A result near the bottom of the range, explained as product that could not be built in time, would weaken the strong-demand story less than one blamed on soft orders. Even so, it would raise questions about execution. Margins matter just as much. Gross margin has crept up from 30.7% toward the low 31% range, and the company is relying on bringing more wafer production in-house at its own fabs to reach its interim target of 35% or better. Higher volumes should spread fixed factory costs more widely and give a visible lift. A flat margin on 14% more revenue would be a warning sign. Communications, which slipped 7% sequentially on weak China smartphone demand, and consumer, still hurt by memory shortages, are the drags most likely to limit upside.
Market positioning leans cautious. Sentiment has slipped to 17.2% bearish from 12.1% before the last report, a modest but meaningful move toward skepticism. At $88.57, the stock sits barely above its 200-day moving average of $87.30 and in the lower third of its post-earnings range of $80.22 to $110.86. That leaves room for a rebound if results impress, but little technical support if they disappoint.
The outlook may matter more than the quarter itself. Management has already said it expects the fourth quarter and 2027 to be stronger than usual, and it now has a proposed Elevate acquisition and early humanoid robotics demand to discuss. What will decide whether the upcycle narrative holds is whether Diodes pairs revenue near $510 million with clear margin expansion and a fourth-quarter guide that shows its supply limits are easing rather than capping growth.
