AT&T, Texas Instruments and Enphase Energy fall premarket; Hasbro rises

Investing.com -- U.S. stock futures rose Wednesday, boosted by the announcement of a trade deal between Japan and the U.S., while investors digested more quarterly earnings.

Here are some of the biggest premarket U.S. stock movers today:

• Tesla (NASDAQ:TSLA) stock rose 0.1% ahead of the electric vehicle manufacturer’s latest earnings, which could result in its biggest drop in quarterly revenue in more than a decade.

• AT&T (NYSE:T) stock fell 3.9% after the telecom giant only maintained its long-term financial outlook, disappointing investors despite beating quarterly profit estimates and adding more wireless subscribers than expected.

• Texas Instruments (NASDAQ:TXN) stock slumped 10% after the chipmaker’s quarterly profit forecast indicated a hit to demand for its analog chips that stoked investor fears of tariff-related disruptions.

• Hasbro (NASDAQ:HAS) stock rose 3.8% after the toy giant reported strong second-quarter earnings, driven by record performance from its Magic: The Gathering franchise.

• General Motors (NYSE:GM) stock rose 1.7%, bouncing after the previous session’s 8% loss after the auto giant said tariffs had taken a $1.1 billion hit on its quarterly earnings.

• Enphase Energy (NASDAQ:ENPH) stock fell 7.4% after the energy technology company issued lower revenue guidance for the third quarter and flagged the impact of newly imposed tariffs.

• GE Vernova (NYSE:GEV) stock rose 4.4% after the electric services company reported stronger-than-expected second-quarter results and raised its full-year guidance, citing robust demand for power and grid infrastructure solutions.

• Hilton Worldwide (NYSE:HLT) stock fell 1.8% after the hotel giant’s system-wide comparable RevPAR (revenue per available room) declined 0.5% on a currency neutral basis compared to the same period in 2024, attributed to modest occupancy declines.

• Thermo Fisher Scientific (NYSE:TMO) stock rose 2.4% after the medical equipment maker reported second-quarter earnings that topped expectations, with revenue also coming in ahead of forecasts.

• Constellation Energy (NASDAQ:CEG) and Vistra Energy (NYSE:VST) both jumped substantially after PJM Interconnection announced the results of its capacity auction for the 2026-2027 delivery year, with the nation’s largest power grid operator setting capacity prices significantly higher than previous auctions.
