- US Steel (X) surged after President Donald Trump backed a partnership between the company and Japan’s Nippon Steel, crediting his tariff policies for an investment that would keep the iconic American firm in the US. While Trump appeared to stop short of endorsing Nippon Steel’s proposed $14.1 billion takeover of US Steel, shares of the American steelmaker surged as much as 26%, on apparent optimism over the deal’s prospects. “I am proud to announce that, after much consideration and negotiation, US Steel will REMAIN in America, and keep its Headquarters in the Great City of Pittsburgh,” Trump said on Truth Social on Friday. “My Tariff Policies will ensure that Steel will once again be, forever, MADE IN AMERICA.” Trump said the partnership would create at least 70,000 jobs and add $14 billion to the US economy, with the bulk of the investment occurring in the next 14 months. He also said he would appear at an event on May 30 in Pittsburgh.

- Informatica (INFA) rose on the word that Salesforce (CRM) is in talks to acquire the software company, rebooting a pursuit that fell through last year, people familiar with the matter said. If a deal is reached, it could be announced as soon as next week, according to the people, who asked to not be identified because the discussions are private. No final decision has been made and talks may still falter or another buyer could emerge, they said. Cloud Software Group has been interested in the asset too, the people said. Shares in Informatica rose as much as 28% on Friday for their biggest intraday gain. Salesforce shares closed lower.

- Booz Allen Hamilton (BAH) shares slumped as much as 19%, the most intraday since 2017, after the defense contractor's forecast fiscal 2026 profit that missed estimates. Management also sees much smaller revenue growth compared to fiscal 2025.
