So what

Leidos reported revenue of $2.58 billion, up from $2.43 billion in the year-ago quarter. Meanwhile, non-GAAP EPS rose from $1.03 to $1.13. These results were ahead of analysts' average forecast for revenue and non-GAAP EPS of $2.48 billion and $1, respectively.

"We delivered a solid Q1 and executed well on our growth strategy while maintaining rigorous discipline on profitability and cash generation," said Leidos CEO Roger Krone in the company's first-quarter earnings release.

Now what

Management reiterated its guidance for full-year revenue between $10.5 billion and $10.9 billion, but it boosted its outlook for both non-GAAP EPS and operating cash flow. Leidos now expects non-GAAP EPS for the year to be between $4.30 and $4.65, up from previous guidance for $4.25 to $4.60. In addition, Leidos now expects operating cash flow at or above $825 million, up from a previous forecast for $725 million or greater.

The revised guidance reflects Leidos' "year-to-date performance and updated expectations," management said in its first-quarter earnings release.
