- Apple (AAPL) delivered a surprisingly strong revenue forecast for the third quarter, even as it warned that memory-chip costs will increase and that shortages of Mac computers will persist for “several months.” Sales will rise 14% to 17% in the period, which runs through June, the company said during a post-earnings conference call Thursday. That range trounced the 9.1% that analysts had anticipated on average, helping send the shares rallying in New York on Friday.

- Oracle (ORCL) has officially agreed to join the list of AI companies working with the Pentagon’s classified networks, according to a post by the Pentagon’s undersecretary for research and engineering on X. Shares of the company high session highs directly following the announcement.

- Roblox (RBLX) shares plunged the most in more than four years on Friday after the video game company reported fewer daily users in the first quarter than analysts expected, due to safety features it implemented to restrict how kids can use the platform.
