Here’s a look at the key metrics from the print.

Alpha & Omega shares are retreating from recent levels.

Why is AOSL stock falling? Alpha And Omega Semiconductor Q4 Highlights Alpha And Omega Semiconductor reported fourth-quarter revenue of $170.37 million, beating analyst estimates of $168 million, according to Pro.

Revenue was down 3.5% on a year-over-year basis, but up 4% quarter-over-quarter driven by continued strength in advanced computing, particularly AI and server applications.

The semiconductor company noted that it’s experiencing ongoing softness in the traditional PC market due to elevated memory pricing.

Alpha And Omega Semiconductor posted an adjusted loss of 13 cents per share for the quarter, beating estimates for a loss of 24 cents per share. “Advanced Computing is now a clear and growing contributor to both revenue and earnings, and combined with an improving pricing environment, we expect this mix shift to support higher gross margins in the second half of calendar 2026,” said Stephen Chang, CEO of Alpha And Omega Semiconductor.

Adjusted gross margin was 23.7% in the second quarter.

The company expects adjusted gross margin to be 23.8% (plus or minus 1%) in the current quarter.

Alpha And Omega Semiconductor also guided for fiscal first-quarter revenue of $166 million to $186 million versus estimates of $180.51 million.

The company’s outlook is below estimates at the midpoint, which may be weighing on shares after hours.
