Key Highlights

  • AEHR shares fell 13.15% to $126.47 from a prior close near $145.61, extending a pullback after the stock more than doubled from the mid-$70s in late July to above $140 within the past week.
  • The decline looks like profit-taking after a parabolic post-earnings rally rather than a reaction to new negative news; the stock's run began with an August 11 fiscal Q4 Earnings beat and accelerated on a follow-on silicon photonics order announcement.
  • Fiscal Q4 2026 Revenue came in at $18.8 million, up 33% year-over-year, with non-GAAP EPS of $0.11 beating expectations, alongside record quarterly bookings of $60.7 million and an effective Backlog of $100.6 million.
  • Management's FY2027 guidance of $130 million-$150 million in revenue, roughly 160%-200% growth and far above the roughly $85 million Street estimate, drove Lake Street and Craig-Hallum to raise price targets to $110 and $125 respectively, both of which now sit below the stock's recent trading range even after today's drop.

Giving Back A Parabolic Rally

Aehr Test Systems shares are pulling back sharply today after an extraordinary run higher over the past week. The stock traded in the mid-$70s in late July, then jumped 27%-31% on its August 11 fiscal fourth-quarter earnings beat, added another 19%-plus on a subsequent silicon photonics order announcement, and continued climbing toward the $140s before today's session. A roughly 13% drop to $126.47 represents a normalization of that move rather than a Reversal tied to fresh negative company news, consistent with profit-taking after a stock has more than doubled in under two weeks.

Blowout Quarter And FY2027 Guide

The rally that preceded today's pullback was fundamentally driven. Aehr's fiscal Q4 2026 revenue reached $18.8 million, up 33% year-over-year, with GAAP Net Income of $1.4 million ($0.04 per share) and non-GAAP EPS of $0.11, versus a loss in the prior-year period. Bookings hit a record $60.7 million, and effective backlog including post-quarter orders reached $100.6 million. Management guided fiscal 2027 revenue to $130 million-$150 million, implying 160%-200% growth and far exceeding the roughly $85 million analysts had modeled, driven by Demand tied to AI processor testing, silicon photonics, and power semiconductor customers expanding wafer-level burn-in capacity.

Analyst Targets Trail The Stock

In the wake of the print, Lake Street doubled its price target to $110 and Craig-Hallum raised its target to $125, both maintaining Buy ratings, but both targets remain below where the stock has been trading, highlighting how far and fast shares outran published estimates. Recent insider sales, including a director's $2.17 million sale on August 4 and a smaller VP sale on August 10, predate the earnings-driven spike but add to a backdrop of valuation caution. Today's decline also comes amid a broader risk-off tone across semiconductor and AI-infrastructure stocks tied to Fabrinet's disappointing post-earnings cash-flow details and rising Treasury yields.

Bottom Line

Aehr Test Systems is down sharply today, but the move follows an outsized post-earnings rally driven by a genuine beat-and-raise quarter, record bookings, and FY2027 guidance well above Street expectations, so today's drop looks more like a cooling-off from overbought levels than a reversal of the underlying growth story. These are the verified facts as reported. Whether shares stabilize may depend on whether Aehr can convert its record backlog and bookings into the delivered revenue needed to justify a valuation that has already run well ahead of even the freshly raised analyst price targets.
