Leidos closes $2.4B ENTRUST acquisition, stakes claim on data center power infrastructure

Leidos closed its $2.4 billion all-cash acquisition of ENTRUST Solutions Group on Tuesday, adding 1,400 engineers and $1.3 billion in annual revenue to its infrastructure division. The target specializes in electric utility modernization, grid automation, and transmission planning — disciplines that matter when a single xAI cluster in Memphis draws 150 megawatts and Dominion Energy is fielding inquiries for 6 gigawatts of new data center load in Virginia alone.

The transaction was announced in September and priced at 7.5x trailing revenue, a 40% premium to Leidos' own trading multiple at the time. ENTRUST's client roster includes 32 of the top 50 U.S. electric utilities. Its engineers manage grid models that handle 1.2 million miles of transmission line. Leidos now holds engineering capacity across substations, distributed energy resources, and the kind of SCADA automation that utilities need when they're asked to route 500 megawatts to a greenfield site in 18 months instead of the traditional 7-year planning cycle.

The timing is structural, not opportunistic. U.S. electricity demand growth sat near zero for two decades. Lawrence Berkeley National Laboratory now projects 4.7% annual growth through 2028, driven almost entirely by data center buildout. That demand is landing in regions where coal retirements have already tightened reserve margins — PJM's 2025 capacity auction cleared at $269.92 per megawatt-day, up 833% from the prior year. Utilities that spent the last decade optimizing for distributed solar and demand response are now engineering point-to-point circuits capable of feeding 100-plus megawatt facilities that run at 95% capacity factor. Leidos bought the firms that write those engineering studies and the substation designs that follow.

The deal reshapes Leidos' revenue mix. Its legacy portfolio tilts toward defense IT and health systems, where growth runs at 3-5% and margins compress under fixed-price contracts. ENTRUST operates on a project basis with 12-18 month durations and 18-22% EBITDA margins. Management guided to $120 million in annual cost synergies by year three, with $80 million coming from shared infrastructure and the remainder from procurement. The combined infrastructure segment now represents 28% of Leidos revenue, up from 19% pre-deal, and carries a backlog valued at $8.1 billion. Worth noting: $2.3 billion of that backlog is tied to grid and energy work, much of it with regulated utilities that face state mandates to interconnect large loads within statutory windows.

Allocators should track two follow-on signals. First, whether Leidos announces partnerships with hyperscale cloud providers or colocation operators in the next 6-9 months — those deals would confirm the company is positioning ENTRUST's engineering capacity as a turnkey solution for power procurement, not just utility consulting. Second, watch for Leidos participation in upcoming Department of Energy grid resilience grants under the Infrastructure Investment and Jobs Act. $10.5 billion in federal grid funding remains unallocated, and ENTRUST's utility relationships position Leidos to capture engineering and program management work on those deployments.

The acquisition doubles Leidos' exposure to the one commodity AI companies cannot synthesize: reliable electricity at the substation fence. Natural gas peakers can't be permitted fast enough. Nuclear restarts face 3-5 year timelines even when the reactor is already built. What's left is engineering — the unglamorous work of transformer specs and relay coordination that turns a signed power purchase agreement into live circuits. Leidos now owns the largest independent bench of engineers who do exactly that, acquired the week before Microsoft announced it would restart Three Mile Island to power its data centers.
