ADCT plunging -56% after disappointing Phase 3 lymphoma trial data; PVH -25% on weak EMEA guidance.(more...)

Tape Overview

Premarket action leans risk-off as heavy selling in mega-cap semiconductors weighs on indices while specific earnings misses trigger deep pullbacks in retail and software.

Top Mover: STI — [Extreme-climate battery tech for space economy]

Solidion Technology, Inc. (STI) is gapping up 321.1% on 44.4M shares after unveiling its Gen-ECB platform. The patented graphene technology targets SpaceX and NASA infrastructure, maintaining performance at -80°C.

Top Loser: ADCT — [Phase 3 trial results and analyst downgrade]

ADC Therapeutics SA (ADCT) collapsed -56.5% on 606K shares following topline results from its LOTIS-5 confirmatory trial. RBC Capital subsequently downgraded the stock, citing concerns over the lymphoma therapy's clinical trajectory.

Also Moving

SciSparc Ltd. (SPRC) surged 50.8% after its subsidiary completed the acquisition of CliniQuantum. Netskope, Inc. (NTSK) fell -22.6% despite an earnings beat, as a CFO retirement and soft net new ARR growth spooked investors. PVH Corp. (PVH) dropped -25.2% after warning that Middle East pressures are hurting EMEA consumer demand. Xos, Inc. (XOS) is down -22.9% on high relative volume following a $6 million direct offering.

Broader Context

Traders are monitoring the semi-conductor complex as Micron Technology, Inc. (MU) and Broadcom Inc. (AVGO) lead the actives list with significant premarket declines.
