Parsons Corporation announced it has acquired Altamira Technologies Corporation, a Northern Virginia-based defense and intelligence contractor, in a transaction valued at up to $375 million as the company looks to deepen its capabilities in signals intelligence and space-related mission work for U.S. national security customers.
Altamira, founded in 1999 and headquartered in McLean, Virginia, brings advanced analytics, SIGINT, cyber operations, missile warning, and space-based mission support to Parsons’ Defense & Intelligence portfolio. Parsons said the acquisition expands its reach across Intelligence Community customers and complements its existing all-domain integration work and Indo-Pacific operations.
Parsons CEO Carey Smith described the deal as an accelerant for the company’s national security growth strategy, positioning the business to pursue a larger share of demand tied to intelligence modernization and multi-domain operations. The company said Altamira has a track record of moving prototypes into operational capabilities quickly, aligning with customer priorities around faster acquisition cycles, digital modernization, and resilient mission architectures.
Altamira employs more than 600 people, with Parsons noting that over 90% hold security clearances. The workforce and operations will be aligned to Parsons’ Defense & Intelligence business unit following the close.
Financially, Parsons said it paid $330 million in cash at closing, with an additional $45 million cash earn-out payable in the first quarter of 2027 if certain EBITDA targets are met during 2026. The base purchase price implies a 12.8x multiple on anticipated 2026 EBITDA contribution, before any revenue or cost synergies, the company said.
Parsons expects Altamira to generate more than $200 million in revenue in 2026 and said the transaction will be accretive to its fiscal 2026 revenue growth rate, adjusted EBITDA margin, and adjusted earnings per share.
Altamira had been backed by ClearSky, McNally Capital, Razor’s Edge, and NIO Advisors. Barclays served as Parsons’ exclusive financial advisor, while Baird advised Altamira.
