Leidos Holdings, Inc. experienced a significant revenue decline in the fourth quarter, reporting $4.21 billion and missing Wall Street's expectations, largely due to the adverse effects of a government shutdown. This revenue drop of 3.6% led to a nearly 3% decline in shares, despite the company achieving adjusted earnings of $2.76 per share. Looking towards the future, Leidos plans for revenue growth in 2026 between $17.5 billion and $17.9 billion, while striving to stabilize amid current market pressures.
