Stock futures were tumbling on Thursday as strikes on key energy facilities in the Middle East drove up oil prices.

These stocks were making moves in premarket trading:

Micron Technology dropped 4.1%, even though the memory-chip maker reported stellar earnings for its second quarter and issued strong guidance. Investors were likely taking the opportunity to lock in some profit, considering that shares are up 348% over the past year due to the boom in artificial intelligence driving a surge in demand for Micron's products.

Other memory stocks were also tumbling following Micron's results. Flash memory product supplier Sandisk slid 4.4%, and hard disk drive makers Seagate Technology and Western Digital were down 1.7% and 2%, respectively.

Alibaba dropped 4.5% after the Chinese online retailer reported a sharp drop in profit and weaker-than-expected revenue for the quarter ended Dec. 31. The results suggest that Alibaba's progress in artificial intelligence isn't outweighing headwinds weighing on its e-commerce business.

Gold miner Newmont was the S&P 500's worst performer ahead of the opening bell, tumbling 5.4%. It came as bullion extended a dismal recent run, tumbling after Federal Reserve Chair Jerome Powell signaled that the central bank wasn't prepared to look past the risk of the war in Iran triggering a flare-up in inflation. When borrowing costs are higher, gold becomes less appealing relative to interest-bearing investments like bonds.

Swarmer traded flat. Shares in the drone technology company jumped 77% on Wednesday, having surged 520% on their stock-market debut Tuesday following an initial public offering.

DLocal rose 7.1% after the Uruguayan fintech's fourth-quarter revenue topped analysts' expectations.

Five Below added 7.6% after the discount store chain issued strong guidance and reported a 15% jump in same-store sales for the fourth quarter, as consumers shop for discounts in a challenging macroeconomic climate.

Red Cat slid 4.7% after the drone and robotics company reported a wider fourth-quarter loss than analysts were expecting, even though revenue surged 1,985% from a year ago.

Accenture, FedEx, Darden Restaurants, Planet Labs, SOLV Energy, Firefly Aerospace, Intuitive Machines, and Signet Jewelers are all set to report earnings on Thursday.
