Financial Performance

Revenues for the nine months ended June 27, 2025, increased by $4,292 million, or 69.5%, to $10,468 million compared to $6,176 million in the prior year. This substantial growth was primarily attributable to the merger with Jacobs Solutions Inc.'s Critical Mission Solutions (CMS) business.

Net income attributable to common shareholders for the nine months ended June 27, 2025, was $26 million, a significant improvement from a net loss of $(108) million in the prior year period. This positive shift reflects the increased revenue volume and improved operating income following the CMS merger.

Net cash provided by operating activities increased by $113 million to $273 million for the nine months ended June 27, 2025, primarily due to increased cash earnings from the CMS merger. Net cash provided by investing activities also saw a substantial increase of $244 million, reaching $236 million, largely driven by the divestiture of the Rapid Solutions business.
