The Numbers Tell a Mixed Story

Amentum Holdings Inc. (AMTM) delivered first-quarter results Monday after the closing bell that had something for everyone to dislike. The company beat earnings expectations with adjusted EPS of 54 cents per share, coming in above the 52-cent analyst consensus. But revenue of $3.24 billion missed estimates of $3.34 billion, according to market data.

That revenue shortfall proved enough to send shares tumbling 9.76% in after-hours trading to $33, even as the company highlighted operational wins. Amentum closed the quarter with a backlog of $47.2 billion and held $247 million in cash and cash equivalents as of Jan. 2.

Management Sees Strength in Strategic Markets

"Amentum's first-quarter results reflect solid operational performance and continued progress on our strategic objectives," said John Heller, CEO of Amentum Holdings.

"Robust bookings across our accelerating growth markets reinforce the strength of our strategy that focuses on the high-demand mission areas of global nuclear energy, space systems and technologies, and critical digital infrastructure."

Outlook Stays Intact

Despite the revenue miss, Amentum reaffirmed its full-year 2026 guidance. The company expects revenue between $13.95 billion and $14.30 billion, with adjusted earnings projected at $2.25 to $2.45 per share.

Executives are scheduled to discuss the quarterly results in more detail during an earnings call at 8:30 a.m. ET Tuesday morning.
