Leidos shares were sliding during the regular session, underperforming peers like CACI and Booz Allen Hamilton, which saw declines of 1.9% and 4.4% respectively. The stock saw a modest recovery in after-hours trading following the announcement that AT&T Chief Operating Officer Jeff McElfresh has been appointed to the company's board of directors effective October 1. This move follows a period of downward pressure for the stock, which had already declined 11.55% over the past month despite projections for 5.52% revenue growth in the upcoming quarter.
