CHANTILLY, Va., April 29, 2026 (GLOBE NEWSWIRE) -- Parsons Corporation (NYSE:PSN) today announced financial results for the first quarter ended March 31, 2026.

CEO Commentary

"Our first quarter results highlighted the resilience of our business and our team's high level of execution, as we delivered our highest adjusted EBITDA margin ever, reached record levels for both total and funded backlog, achieved a robust book-to-bill ratio of 1.4x in both segments, and generated record first quarter cash flow. Revenue performance was in line with our expectations, and we continued to complement our organic growth with strategic, accretive acquisitions that enhance our differentiation and drive long-term shareholder value," said Carey Smith, chair, president, and chief executive officer.

"Looking forward, we are very optimistic about our future. There is increasing global demand for both defense and infrastructure. Our ability to deliver operationally relevant solutions with speed, digitally transform our offerings, and leverage non-traditional commercial business models enables us to uniquely meet our customers' critical needs. We have a unique and synergistic Critical Infrastructure and Federal Solutions portfolio, consisting of six growing, profitable, and enduring end-markets. With our record total and funded backlog, robust pipeline of large opportunities, strong win rates, and $11 billion in awarded contracts not yet booked, we believe we are well positioned to deliver for our customers and shareholders."

First Quarter 2026 Results

Year-over-Year Comparisons (Q1 2026 vs. Q1 2025)

Total revenue for the first quarter of 2026 decreased by $63 million, or 4%, to $1.5 billion and was down 8% on an organic basis. Excluding the company's confidential contract, total revenue increased 8% and organic revenue increased 3% driven by growth in the company's Critical Infrastructure and Protection, Space and Missile Defense, and Transportation markets. Operating income decreased 12% to $96 million primarily due to lower volume on the company's fixed-price confidential contract, and higher acquisition-related expenses. Net income decreased 20% to $53 million due to the items noted above. GAAP diluted earnings per share (EPS) attributable to Parsons was $0.49 in the first quarter of 2026, compared to $0.60 in the prior year period.

Adjusted EBITDA including noncontrolling interests for the first quarter of 2026 was $151 million, a 1% increase over the prior year period. Adjusted EBITDA margin expanded 50 basis points to 10.1% compared to 9.6% in the first quarter of 2025. These increases were driven by improved execution and contributions from accretive acquisitions, offsetting lower revenue on the company's confidential contract. Adjusted diluted EPS was $0.79 in the first quarter of 2026, compared to $0.78 in the first quarter of 2025. The year-over-year adjusted diluted EPS increase was driven by the items that impacted adjusted EBITDA above.

Segment Results

Critical Infrastructure Segment

First quarter 2026 Critical Infrastructure revenue increased $21 million, or 3%, from the first quarter of 2025. This increase was driven by organic growth of 2% and inorganic revenue contributions from the company's TRS Group and Applied Sciences acquisitions. Organic growth was primarily driven by the Global Transportation markets.

First quarter 2026 adjusted EBITDA including noncontrolling interests increased by $6 million, or 8%, compared to the prior year period. Adjusted EBITDA margin expanded 50 basis points to 10.8% from 10.3% in the prior year period. Both adjusted EBITDA dollars and margins were first quarter records for Critical Infrastructure. These increases were driven by the ramp-up of recent contract awards, accretive acquisitions and strong program execution.

First quarter 2026 Federal Solutions adjusted EBITDA including noncontrolling interests decreased by $4 million, or 5% from the first quarter of 2025, and adjusted EBITDA margin increased 40 basis points to 9.4%.

Additional Corporate Highlights

Parsons continues its successful track record of acquiring strategic companies in high-growth markets that strengthens its portfolio. During the quarter, the company was named one of the World's Most Ethical Companies by Ethisphere for the 17th consecutive year. Parsons was also recognized for delivering project excellence on two major infrastructure programs.

During the first quarter of 2026, Parsons closed its acquisition of Altamira Technologies Corporation, a Northern Virginia-based signals intelligence and space solutions provider, in an all-cash transaction valued at up to $375 million. Altamira advances high priority national security missions supporting intelligence community and Department of War customers by providing multi-intelligence technology solutions and performing critical operations. Altamira expands Parsons' market presence in signals intelligence, missile warning, space, and foreign military exploitation, and adds critical customer depth with the National Air and Space Intelligence Center, National Security Agency, and other classified intelligence customers. The transaction is consistent with Parsons' strategy of completing accretive acquisitions with revenue growth and adjusted EBITDA margins of at least 10%.
Named by Ethisphere as one of the 2026 World's Most Ethical Companies. The company has been honored with this recognition for 17 consecutive years.
Recognized with the Engineering Excellence Honor Award from the American Council of Engineering Companies (ACEC) of Georgia for the company's work on the Akers Mill Ramp Extension project in Cobb County.
Honored with the Refurbishment and Retrofit Project of the Year award at the Big Project Middle East Awards 2026 for the company's work on the King Abdullah Finance District Residential Uplift project. This award marks the third consecutive year that the company's Europe Middle East and Africa team has been recognized for exceptional work.

Fiscal Year 2026 Guidance

The company is reiterating its fiscal year 2026 revenue, adjusted EBITDA, and operating cash flow guidance ranges. The table below summarizes the company's fiscal year 2026 guidance.

	Current Fiscal Year 2026 Guidance	Growth at the Mid-point
Revenue	$6,500 million - $6,800 million	+4.5% growth and +0.6% organically; +10.5% growth and +6% organically excluding confidential contract
Adjusted EBITDA including non-controlling interest	$615 million - $675 million	+6% growth (10 bps expansion)
Cash Flow from Operating Activities	$470 million - $530 million	+5% growth

We have not provided a reconciliation of our Adjusted EBITDA guidance because the information needed to reconcile this measure is unavailable due to the inherent difficulty of forecasting the timing or amount of various items that have not yet occurred which may be significant. Additionally, estimating such GAAP measure and providing a meaningful reconciliation for future periods requires a level of precision that is unavailable for these future periods and cannot be accomplished without unreasonable effort.

Non-GAAP Financial Information

The tables under "Parsons Corporation Inc. Reconciliation of Non-GAAP Measures" present Adjusted Net Income attributable to Parsons Corporation, Adjusted Earnings per Share, Earnings before Interest, Taxes, Depreciation, and Amortization ("EBITDA"), Adjusted EBITDA, EBITDA Margin, and Adjusted EBITDA Margin, reconciled to their most directly comparable GAAP measure. These financial measures are calculated and presented on the basis of methodologies other than in accordance with U.S. generally accepted accounting principles ("Non-GAAP Measures"). Parsons has provided these Non-GAAP Measures to adjust for, among other things, the impact of amortization expenses related to our acquisitions, costs associated with a loss or gain on the disposal or sale of property, plant and equipment, restructuring and related expenses, costs associated with mergers and acquisitions, software implementation costs, legal and settlement costs, and other costs considered non-operational in nature. These items have been Adjusted because they are not considered core to the company's business or otherwise not considered operational or because these charges are non-cash or non-recurring. The company presents these Non-GAAP Measures because management believes that they are meaningful to understanding Parsons's performance during the periods presented and the company's ongoing business. Non-GAAP Measures are not prepared in accordance with GAAP and therefore are not necessarily comparable to similarly titled metrics or the financial results of other companies. These Non-GAAP Measures should be considered a supplement to, not a substitute for, or superior to, the corresponding financial measures calculated in accordance with GAAP.

¹Book-to-Bill ratio is calculated as total contract awards divided by total revenue for the period.
