U.S. stock futures moved modestly lower on Tuesday as investors returned from a holiday and began parsing a new round of corporate reports and market-moving headlines.
Below are the most significant moves in the premarket session and the company-specific developments behind them:
Palo Alto Networks (NASDAQ:PANW) - The cybersecurity specialist saw its shares slip 0.8% in premarket trading ahead of the release of its latest quarterly results after the close. The company had previously raised its full-year revenue and profit guidance in November, attributing that upgrade to a surge in demand for its digital security products aimed at countering online threats.
General Mills (NYSE:GIS) - Shares of the packaged foods maker dropped 3.4% after the firm reduced its full-year core net sales and profit outlooks, citing softer consumer sentiment. The company now anticipates annual sales to fall between 1.5% and 2%, versus the prior range of down 1% to up 1%.
Norwegian Cruise Line (NYSE:NCLH) - The cruise operator rallied 7.5% after a report that activist investor Elliott has accumulated a stake exceeding 10% in the company.
Masimo (NASDAQ:MASI) - The medical device maker jumped 34% following a Financial Times report that Danaher (NYSE:DHR) is nearing a deal worth nearly $10 billion to acquire the company.
Medtronic (NYSE:MDT) - Shares fell 3.7% after the medical device company reported a third-quarter profit decline, which the company said was mainly due to higher expenses.
Warner Bros Discovery (NASDAQ:WBD) - Stock rose 2.9% after the company rejected Paramount Skydance’s (NASDAQ:PSKY) latest hostile bid of $30 a share, while giving Paramount Skydance seven days to present an improved offer.
Qualcomm (NASDAQ:QCOM) - The chipmaker slipped 0.8% even as it said a London lawsuit alleging abuse of its market position to extract inflated royalties from Apple and Samsung would be withdrawn.
Shopify (NASDAQ:SHOP) - The e-commerce platform’s shares inched up 0.1% after Truist Securities upgraded its rating to buy from hold, arguing that a broad software selloff tied to AI concerns has created a favorable long-term entry point.
These premarket moves reflect a mix of earnings-related updates, shifts in investor sentiment and deal-related reporting. With several companies slated to report results after the bell, markets will be watching how guidance and expense trends influence near-term expectations.
Impacted sectors include cybersecurity, consumer packaged goods, travel and leisure, medical devices, media and entertainment, semiconductors and e-commerce.
