After-Hours Stock Movers:

AeroVironment (NASDAQ: AVAV)

AeroVironment skyrocketed 19% after posting a strong Q4 beat, with EPS hitting $1.84 ($0.36 ahead of expectations) and revenue surging to $641.6 million against the $557.37 million consensus. Investors overlooked mixed fiscal year 2027 guidance—where projected EPS of $3.02 to $3.34 fell short of the $3.79 Wall Street estimate—and instead focused on robust top-line momentum. The defense contractor's strong revenue outlook of up to $2.23 billion confirms continued high demand for its uncrewed aircraft systems.

Praxis Precision Medicines (NASDAQ: PRAX)

Praxis shares slid 7% following news that the FDA extended the review period for its neuroscience drug, relutrigine, by three months, pushing the PDUFA target action date to December 27, 2026. The delay stems from the FDA categorizing Praxis's submission of additional data sensitivity analyses as a "major amendment." Crucially, the regulatory agency did not request any new clinical trials or cite safety concerns, keeping the application active and ongoing.

Vishay Intertechnology (NYSE: VSH)

Vishay plummeted 10% after announcing the commencement of an underwritten public offering of $750 million in common stock, with a 30-day option for underwriters to buy an additional $112.5 million. The substantial share dilution took investors by surprise as the electronic components manufacturer moves to raise capital.

Concentrix Corporation (NASDAQ: CNXC)

Concentrix cratered 26% following a disappointing fiscal Q2 report where it narrowly missed both earnings and revenue expectations. The real damage came from management’s downbeat forward guidance, with full-year 2026 EPS cut to a range of $10.83–$11.18, well below the $11.71 consensus. The customer experience tech firm is clearly grappling with slower enterprise spending and pricing pressures.

SharonAI Holdings

SharonAI exploded 78% higher following a bullish regulatory filing revealing a massive insider position. The disclosure showed that Situational Awareness LP holds nearly 1.7 million shares of Class A common stock alongside pre-funded warrants for an additional 6.37 million shares. This substantial show of institutional backing triggered a frenzy of retail buying in the high-performance computing and AI infrastructure play.
