The first-quarter earnings season has been sensational. Many companies knocked it out of the park when delivering earnings and revenue numbers that well beyond expectations. With reports now in from about 96% of S&P 500 companies, earnings have climbed a staggering 29% from last quarter. Information Technology, up 56%, and Communication Services, up 51%, have led the pack. At the bottom are Healthcare, down 3%, and Energy, down 1%. With earnings season essentially over, we have had a chance to look at trends. In particular, we watch for companies that raised guidance as we view that action as a likely catalyst for market-beating returns in the quarters ahead. It's even harder for companies to raise guidance during uncertain economic times, as vision is murky. The following is a partial list of companies in Argus' Fundamental Universe of Coverage where management raised its outlook during the 1Q26 reporting season.
