Revenue, Performance Obligation, Impact of Changes in Estimates

The aggregate impact of changes in estimates decreased our revenues and operating income as follows:

						Three Months Ended June 30,									Six Months Ended June 30,
						2025						2024			2025						2024
						(In thousands)									(In thousands)
Revenues (1)						$	17,520					$	(2,098)		$	5,930					$	(2,791)
Operating Income (1)						$	17,605					$	(2,079)		$	6,046					$	(3,350)

(1)During the three months ended June 30, 2025, our Government Operations segment results were favorably impacted by contract adjustments related to a nuclear operations contract. These adjustments resulted in an increase in revenue and operating income of $29.4 million for the three and six months ended June 30, 2025. During the three and six months ended June 30, 2024, no adjustments to any one contract had a material impact on our consolidated financial statements.
