Filing Highlights

Financial Performance

Revenues increased by 72.3% to $3.416 billion for the three months ended December 27, 2024, compared to $1.983 billion for the same period in the prior year. This increase is primarily attributed to the merger with CMS (Critical Mission Solutions).

The effective tax rate was 53.3% for the three months ended December 27, 2024, compared to (56.0)% for the three months ended December 29, 2023. The change is primarily due to the recognition of a valuation allowance against a disallowed interest expense deferred tax asset.

Net income attributable to common shareholders increased by $53 million, from a loss of $41 million to a profit of $12 million. This improvement is primarily driven by the contributions from the CMS merger.
