Leidos Holdings closed its $2.4 billion acquisition of ENTRUST Solutions this week, adding grid modernization and transmission engineering to a portfolio built on defense IT and weapons systems integration. The timing is deliberate. US data center power demand is projected to triple by 2030, and the constraint is no longer silicon or capital—it is transformer capacity and substation engineering.

ENTRUST designs and deploys utility-scale grid infrastructure: transmission lines, substations, renewable interconnections. Leidos paid 12.8x trailing EBITDA for the business, a 37% premium to comparable infrastructure engineering multiples. The seller, private equity sponsor Arlington Capital, had owned ENTRUST for four years and returned approximately 2.1x gross on a $950 million equity check. Leidos financed the deal with $1.8 billion in term debt and $600 million in revolver draws, raising net leverage from 2.1x to an estimated 3.4x EBITDA.

The strategic rationale is narrow and defensible. Hyperscalers are signing 15 to 25-year power purchase agreements with utilities, but those megawatt commitments mean nothing without physical infrastructure to deliver electrons. ENTRUST's backlog sits at approximately $1.1 billion, with 68% tied to data center interconnection projects and utility grid hardening. Leidos now controls engineering capacity that Microsoft, Amazon, and Google need but cannot build internally. The company disclosed that ENTRUST's revenue grew 22% annually over the past three years, with EBITDA margins in the low teens—consistent with engineering services but with visibility that pure-play contractors lack.

This is not a bet on renewables or decarbonization theater. It is a bet that AI training runs and inference clusters require firm, dispatchable power at scale, and that the engineering bottleneck for both fossil and renewable generation is grid integration. Leidos already holds $35 billion in federal contract backlog, much of it tied to Department of Defense modernization. Adding grid infrastructure creates optionality in a market where the US needs to build or upgrade an estimated 200 to 300 substations over the next decade to support data center load growth. ENTRUST's 1,400 engineers are now under contract to a buyer with access to federal project finance and a client base that includes utilities in 38 states.

Operators should monitor Leidos' next two quarterly earnings calls for integration execution and whether ENTRUST's backlog conversion accelerates. The Federal Energy Regulatory Commission is expected to issue updated interconnection queue rules in Q2 2025, which could either compress or extend project timelines. Watch for Leidos to announce partnerships with specific hyperscalers or utilities—those would signal that the company is moving from infrastructure provider to strategic co-developer. The debt load is manageable but leaves little room for multiple expansion until leverage drops below 3.0x, likely by late 2026.

The $2.4 billion check is the largest acquisition in Leidos history. It prices in the assumption that grid capacity is the next decade's chokepoint, not compute or capital. If that assumption holds, the premium was cheap.
