Parsons Corporation's stock experienced a significant pre-market decline of 5.28% on Wednesday, following the release of its fourth-quarter and full-year 2025 financial results.

The engineering and consulting firm reported quarterly adjusted earnings of $0.75 per share, falling short of the analyst consensus estimate of $0.79. Revenue for the quarter came in at $1.60 billion, which was below the expected $1.67 billion and represented an 8% decrease compared to the same period last year.

Adding to investor concerns, the company issued its fiscal year 2026 revenue guidance in the range of $6.5 billion to $6.8 billion. The midpoint of this forecast is below the analyst estimate of $6.65 billion, signaling potentially weaker-than-expected performance in the coming year.
