**Parsons Acquires Altamira Technologies Corporation**

***Acquisition bolsters Parsons' signals intelligence and space solutions for the U.S. Department of War***

CHANTILLY, VA (Jan 15, 2026) – Parsons Corporation (NYSE:PSN) announced today that it has acquired Northern Virginia-based Altamira Technologies Corporation in a transaction valued up to $375 million. Founded in 1999, Altamira enhances Parsons' defense and intelligence portfolio by delivering advanced analytics, signals intelligence (SIGINT), cyber, missile warning, and space capabilities, complementing the company's strengths in all-domain technology integration and Indo-Pacific operations, and expanding with Intelligence Community (IC) customers.

"Acquiring Altamira is a strategic accelerator for our national security growth strategy, strengthening Parsons' ability to deliver rapid and agile mission-ready, intelligence-driven solutions across the Department of War and the Intelligence Community," said Carey Smith, chair, president, and CEO of Parsons. "Altamira's advanced intelligence, surveillance, and reconnaissance (ISR), and analytics capabilities, plus their space-based mission solutions expand our capabilities and position us to capture a larger share of the rapidly evolving intelligence and multi-domain operations market. Their deep commitment to solving the nation's most complex security challenges aligns seamlessly with Parsons' mission, culture, and our alignment to the Department of War's acquisition-transformation strategy."

Altamira is headquartered in McLean, Virginia, and is recognized for its exceptional employees whose elite expertise and clearances enable high-end engineering, analytics, and mission technologies that support

some of the nation's most sensitive intelligence, space, and defense programs. With core strengths in missile warning, AI/ML-enabled analytics, space-based mission support, and SIGINT/cyber operations, Altamira provides customers with the ability to detect, characterize, and respond to emerging threats across all domains. The company has a proven track record of rapidly transitioning innovative prototypes into operational capabilities, directly supporting the Department of War and IC's push for faster acquisition cycles, digital modernization, and resilient mission architecture.

"We are excited to join forces with Parsons, a partnership that reflects our shared commitment to innovation, mission excellence, and delivering decisive advantages to the warfighter," said Jane Chappell, CEO of Altamira. "Our cultures are deeply aligned with both organizations prioritizing agility, technical excellence, and a relentless focus on customer mission outcomes. Together, we will leverage our combined strengths to expand our impact, accelerate capability delivery, and provide the cutting-edge solutions required to meet the Department of War and Intelligence Community's evolving operational and acquisition priorities."

Altamira has been a portfolio company of ClearSky, a venture capital/growth equity firm investing in critical security companies. "ClearSky is very excited to have supported Altamira during its growth, and to have contributed to strengthened national security through Altamira's execution and innovation," said Alex Weiss, CEO, co-founder and managing partner of ClearSky. "This exit further confirms the success of ClearSky's focus on investing in a safer world."

The transaction is consistent with Parsons' strategy of completing accretive acquisitions of companies with revenue growth and adjusted EBITDA margins of at least 10%, while adding critical intellectual property that strengthens the company's existing portfolio. Altamira's more than 600 talented employees, over 90 percent of whom hold security clearances, will be aligned to Parsons' Defense & Intelligence business unit.

Parsons paid $330 million of cash at closing for Altamira, with an additional $45 million cash earn out payable in Q1 2027 if certain EBITDA targets are met during 2026. The base purchase price implies a 12.8x multiple on the anticipated Altamira 2026 EBITDA contribution before considering any revenue or cost synergies. Parsons estimates Altamira will generate over $200 million of revenue in 2026 and that the transaction will be accretive to Parsons' fiscal year 2026 revenue growth rate, adjusted EBITDA margin, and adjusted earnings per share. Barclays acted as the exclusive financial advisor to Parsons and Baird acted as the exclusive financial advisor to Altamira.
