Stock futures were sliding Friday with investors anxious over the artificial-intelligence trade and tensions between the U.S. and Iran.
These stocks were making moves in premarket trading:
Netflix gained 7.9% after the video streamer said it would drop out of the bidding war for Warner Bros. Discovery, which late Thursday deemed an offer of $31 a share from Paramount Skydance superior. Paramount's own shares jumped 7.3%, and Warner fell 2.1% to $28.20. The view among most investors was that Netflix was overpaying with its original $82 billion offer for Warner Bros.'s streaming and studios assets.
Block surged 18%, making it the S&P 500's biggest gainer ahead of the opening bell. The payment services company, which owns the Square and CashApp platforms, said on Thursday that it would cut 4,000 workers, or 40% of its workforce, citing the disruption that artificial intelligence would cause to its industry. Block also raised its guidance for 2026.
Dell Technologies rallied 11% after the tech hardware maker topped analysts' fourth-quarter earnings expectations. Dell makes servers and networking equipment that companies use to help power AI, and strong demand for that hardware has boosted the company's top and bottom lines.
Nvidia rose 0.3%, having tanked 5.5% on Thursday following its fourth-quarter results. Thursday marked the stock's largest one-day percentage decline since April 2025, erasing $259 billion in market capitalization.
CoreWeave sank 12% after the neocloud provider reported a wider fourth-quarter loss than Wall Street expeted. CoreWeave's first-quarter sales guidance and fiscal-year adjusted operating margin outlook also missed expectations.
Duolingo sank 25% after the education technology company reported better-than-expected first-quarter earnings but said it would sacrifice revenue growth in a bid to reach 100 million daily active users by 2028. "We are deliberately prioritizing user growth and teaching better ... even though that moderates near-term financial growth," said CEO Luis von Ahn.
Flutter Entertainment plunged 15% after the FanDuel owner missed analysts' fourth-quarter earnings estimates. The company's forecast for its full-year results in the U.S. also came up short. CEO Peter Jackson told Barron's that a somewhat boring NFL season was one reason for the weaker-than-expected results.
Intuit was the S&P 500's worst performer in Friday's premarket session, falling 3.9%. The financial software company beat Wall Street's earnings target for its fiscal second quarter but its guidance missed the mark.
NCR Atleos rallied 15% after Brink's agreed to buy the ATM provider. The deal includes 13.3 million shares of Brink's common stock and $2.2 billion in cash, plus the assumption of about $2.6 billion of NCR Atleos' debt.
Rocket Lab slid 4.9% after the launch service provider reported a narrower-than-expected loss for the fourth quarter. Sales and guidance also beat analysts' estimates. Investors may have been taking the opportunity to lock in some profit, given that the shares have risen 242% over the past 12 months through Thursday's close.
Zscaler tumbled 9.2% after the cybersecurity company beat analysts' earnings estimates for its fiscal second quarter, and issued solid guidance. Software stocks have been volatile this week as investors continue to worry that AI could upend the industry.
