Biggest stock movers Thursday

Biggest stock gainers
QuantumScape $QS +21% - Shares surged following Q2 results as it highlighted improved profitability and expanding demand beyond autos, with growing interest in its solid-state battery tech from military, aerospace, and government sectors. The company also pointed to a new opportunity in AI data center power infrastructure, where higher energy density could enable greater compute capacity. Progress on its Eagle Line and QSE-5 cell production further reinforced confidence in scaling, shifting the narrative from execution risk to broader commercial potential.
Texas Instruments $TXN +11% - Shares jumped after delivering a strong Q1 beat and upbeat guidance, signaling improving demand trends. The company reported EPS of $1.68 vs. $1.37 estimates and revenue of $4.83B (+19% Y/Y), driven by robust analog sales and strength in industrial and data center markets. Looking ahead, TXN guided Q2 EPS to $1.77–$2.05 and revenue to $5B–$5.4B, both well above consensus, reinforcing confidence in a cyclical recovery and sustained momentum.
Biggest stock losers
ServiceNow $NOW -12% - Shares tumbled despite strong Q1 results, as a weaker-than-expected margin outlook overshadowed solid growth. The company beat on revenue ($3.77B, +22% Y/Y) and matched EPS while raising both Q2 and full-year subscription revenue guidance, with remaining performance obligations jumping 25%. However, full-year subscription gross margin guidance of 81.5% came in below expectations, driven by acquisition-related dilution, and weighed on investor sentiment. Additional concerns around delayed large deal closures in the Middle East added to the pressure, shifting focus from top-line strength to near-term profitability.
Altimmune $ALT -12% - Shares plunged after pricing an upsized, oversubscribed $225M public offering of common stock, pre-funded warrants, and accompanying warrants. The deal includes 64.25M shares and warrants exercisable at $3.00 per share, signaling near-term dilution concerns despite strong demand.
International Business Machines $IBM -7% - Shares fell despite a solid Q1 beat, as unchanged full-year guidance disappointed investors. The company reported EPS of $1.91 and revenue of $15.92B (+9.5% Y/Y), with strength across software and mainframe-driven infrastructure, alongside better-than-expected free cash flow. However, management reiterated its outlook for ~5% constant-currency revenue growth, roughly in line but slightly below expectations, signaling limited upside despite a strong start. The lack of a guidance raise kept pressure on valuation multiples, overshadowing otherwise steady execution.
Tesla $TSLA -3% - Shares fell as investors looked past the Q1 beat and focused on the company’s heavier spending plans and execution risks. Tesla signaled more than $25B in combined 2025–2026 capex, with Optimus production targeted for late July or August and Robotaxi expansion aimed at a dozen states by year-end, underscoring a long investment cycle before meaningful monetization. The company also disclosed a potential $2 billion stock-based acquisition of an AI hardware firm, with much of the deal tied to performance milestones, adding to concerns around near-term cash use even as Tesla continues to highlight its autonomy and robotics roadmap.
