Engineering & Consulting: The increase in gross profit was attributable to higher revenue partially offset by modestly lower gross margin resulting from lower sustainability consulting revenue, which typically generates higher margins. Additionally, 2023 gross profit benefited from $7.4 million in revenue related to one-timeamendments to several contracts with a developer in exchange for discounted fees. Installation & Maintenance: The increase in gross profit was primarily attributable to higher revenue. The increase in gross profit margin was driven by several larger projects with higher margins. Selling, General & Administrative The increase in selling, general and administrative expenses is primarily attributable to a $29.7 million increase in compensation costs during the period resulting from more headcount. Additionally, there was an increase in professional fees of $7.4 million as compared to the prior year related primarily to IT costs, acquisition-related costs and other costs related to our strategic initiatives. 94
