4. Operating margin for the three months ended September 30, 2025 was 9.4% compared to an operating margin of 9.8% for the three months ended September 30, 2024. As described in further detail below, the quarterly increase in operating income was predominantly driven by greater contribution from our United States construction segments, due to the revenue growth they experienced, while the 40 basis point reduction in operating margin was attributable to a decrease in the operating margin of our United States electrical construction and facilities services segment. For the nine months ended September 30, 2025, operating income was $1,139.7 million, an increase of $183.4 million compared to operating income of $956.3 million for the nine months ended September 30, 2024. Operating margin for the nine months ended September 30, 2025 was 9.1% compared to an operating margin of 8.9% for the nine months ended September 30, 2024. Operating income for the nine months ended September 30, 2025 included incremental acquisition contribution of $23.3 million, net of amortization expense attributable to identifiable intangible assets of $35.8 million. Excluding the impact of acquisitions, and as described in more detail below, the year-over-year increase in profitability was predominantly a result of improved operating performance within our United States construction segments, due to a more favorable mix of work and better project execution, including enhanced productivity, due in part to investments in virtual design and construction, prefabrication, and automation. 

Operating income of our United States electrical construction and facilities services segment was $145.2 million, or 11.3% of revenues, for the three months ended September 30, 2025, compared to $119.1 million, or 14.1% of revenues, for the three months ended September 30, 2024. Operating income of this segment for the nine months ended September 30, 2025 was $438.9 million, or 11.8% of revenues, compared to $299.3 million, or 12.4% of revenues, for the nine months ended September 30, 2024. Largely driven by Miller Electric, this segment’s operating income for the nine months ended September 30, 2025 included incremental acquisition contribution of $21.6 million, net of amortization expense attributable to identifiable intangible assets of $30.8 million
