Fiscal Year 2026 Guidance

The company is narrowing and reiterating the mid-point of its fiscal year 2026 revenue and adjusted EBITDA guidance ranges and reiterating its operating cash flow guidance range.

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 measures 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.
