COMFORT SYSTEMS USA REPORTS SECOND QUARTER 2023 RESULTS
Houston, TX — July 26, 2023 — Comfort Systems USA, Inc. (NYSE: FIX) (the “Company”) today reported results for the quarter ended June 30, 2023.
For the quarter ended June 30, 2023, net income was $69.5 million, or $1.93 per diluted share, as compared to $42.2 million, or $1.17 per diluted share, for the quarter ended June 30, 2022. Revenue for the second quarter of 2023 was $1,296.4 million compared to $1,017.9 million in 2022. The Company reported operating cash flow of $125.4 million in the current quarter compared to $44.6 million in 2022.
Brian Lane, Comfort Systems USA’s President and Chief Executive Officer, said, “Strong ongoing demand and remarkable execution by our workforce resulted in another superb quarter. Our mechanical operations continued to perform at high levels, and electrical segment margins increased significantly. This quarter benefited from continued growth and solid performance in our modular business, and service maintained its upward trajectory. Our strong execution and favorable payment terms on new work combined to produce robust second quarter cash flow.”
Backlog as of June 30, 2023 was $4.19 billion as compared to $4.44 billion as of March 31, 2023 and $2.81 billion as of June 30, 2022. On a same-store basis, backlog increased from $2.81 billion as of June 30, 2022 to $4.11 billion as of June 30, 2023.
Mr. Lane continued, “Our backlog continues to track at unprecedented levels despite our strong revenue. Year over year backlog increased nearly 50%, by $1.4 billion, while sequential backlog tracked down 6% as we performed work on the heavy pre-bookings late last year in our modular construction business.”
The Company reported net income of $126.7 million, or $3.53 per diluted share, for the six months ended June 30, 2023, as compared to $129.0 million, or $3.57 per diluted share, in 2022. The first six months of 2023 included a diluted per share net gain of $0.15 due to a tax change, including $0.08 related to prior tax years, and $0.15 from the favorable resolution of certain litigation matters. The first quarter of 2022 included a diluted per share net tax gain of $1.49 related to prior years. The Company also reported revenue of $2.47 billion for the six months ended June 30, 2023, as compared to $1.90 billion in 2022. Operating cash flow for the six months ended June 30, 2023 was $252.3 million, as compared to $108.3 million in 2022.
Mr. Lane concluded, “Thanks to the extraordinary execution by our teams, and in light of persistently high demand, we continue to expect strong results for the remainder of this year and well into 2024.”
