SAN JOSE, California - August 13, 2026 - Legence Corp. (Nasdaq: LGN) (“Legence” or the “Company”) today reported financial results for the second quarter ended June 30, 2026.

“Strong customer demand led to another record quarter for Legence, with new highs in revenue, Adjusted EBITDA and backlog and awarded contracts,” said Jeff Sprau, Chief Executive Officer of Legence. “Total revenue more than doubled year over year, with revenue growth, excluding the impact of The Bowers Group (“Bowers”) acquisition, of approximately 60%. While the data centers & technology end market continues to be a significant driver of our performance, we are also benefitting from healthy activity across our other diverse end markets, including life sciences & healthcare, state & local government, and education. Our dedicated craftspeople, technicians, and engineering professionals are executing at the highest standards, and we are leveraging the scalability of our growth platform to drive sequential Adjusted EBITDA Margin expansion. As we enter the second half of 2026, healthy industry conditions, combined with our backlog-supported visibility, gives us confidence to raise our revenue and profit outlook for the year.”

Second Quarter 2026 Consolidated Results:

Revenues for the second quarter 2026 totaled $1.26 billion, an increase of 110.7% from $598.9 million for the second quarter 2025. Excluding the impact of the Bowers acquisition, non-GAAP revenue growth was 60.0%. Gross profit for the second quarter 2026 was $220.2 million with gross margin of 17.4%, compared to gross profit of $128.7 million and gross margin of 21.5% for the second quarter 2025. Excluding the impact of compensation related to legacy Series A Interests and Restricted Series C Interests paid for by entities outside of Legence, we generated non-GAAP Adjusted Gross Profit of $234.0 million and non-GAAP Adjusted Gross Margin of 18.5% for the second quarter 2026, compared to non-GAAP Adjusted Gross Profit of $130.3 million and non-GAAP Adjusted Gross Margin of 21.8% for the second quarter 2025. The decrease in non-GAAP Adjusted Gross Profit and non-GAAP Adjusted Gross Margin was primarily due to a revenue mix shift towards Installation & Maintenance and a slight decline in Engineering & Consulting Adjusted Gross Margin. Net loss attributable to Legence for the second quarter 2026 was $27.8 million, or $(0.37) per diluted share, compared to a net loss attributable to Legence of $5.3 million for the second quarter 2025. Net loss for the second quarter 2026 was $34.6 million, compared to a net loss of $3.9 million for the second quarter 2025. Non-GAAP Adjusted EBITDA for the second quarter 2026 was $154.6 million, an increase of 114.1% from $72.2 million for the second quarter 2025. Refer to “Non-GAAP Financial Measures” for definitions of revenue growth (excluding Bowers), Adjusted Gross Profit, Adjusted Gross Margin, Adjusted EBITDA and Adjusted EBITDA Margin and a reconciliation of each to the most directly comparable GAAP measure.

Engineering & Consulting Segment Results:

Engineering & Consulting segment revenue for the second quarter 2026 totaled $206.9 million, an increase of 5.5% from $196.1 million for the second quarter 2025, driven by higher demand for Program & Project Management services primarily from state & local government and data centers & technology clients, partially offset by lower revenue from Engineering & Design services primarily from mixed-use clients.

Engineering & Consulting segment gross profit for the second quarter 2026 totaled $56.1 million, a decrease of 12.4% from $64.1 million for the second quarter 2025. Excluding the impact of compensation related to legacy Series A Interests and Restricted Series C Interests paid for by entities outside of Legence, we generated non-GAAP Adjusted Gross Profit of $64.3 million and non-GAAP Adjusted Gross Margin of 31.1% for the second quarter 2026, compared to non-GAAP Adjusted Gross Profit of $65.1 million and non-GAAP Adjusted Gross Margin of 33.2% for the second quarter 2025. Refer to “Non-GAAP Financial Measures” for definitions of Adjusted Gross Profit and Adjusted Gross Margin and a reconciliation of each to the most directly comparable GAAP measure. The decrease in non-GAAP Adjusted Gross Profit was primarily driven by lower non-GAAP Adjusted Gross Margin, partially offset by higher revenue. The decrease in non-GAAP Adjusted Gross Margin was primarily driven by a revenue mix shift towards the Program & Project Management service line and rising indirect customer fulfillment costs.

Installation & Maintenance Segment Results:

Installation & Maintenance segment revenue for the second quarter 2026 totaled $1.06 billion, an increase of 162.0% from $402.8 million for the second quarter 2025. Excluding the impact of the Bowers acquisition, non- GAAP Installation & Maintenance segment revenues grew by 86.6% over the comparable periods.³ The increase was driven by strong demand for our Installation & Fabrication services, primarily from data centers & technology clients. The increase in Maintenance & Service revenue was primarily from data centers & technology, education, state & local government and life sciences & healthcare clients. See the section titled “Non-GAAP Financial Measures” for more information about non-GAAP revenue growth (excluding Bowers).

Installation & Maintenance segment gross profit for the second quarter 2026 totaled $164.1 million, an increase of 154.1% from $64.6 million for the second quarter 2025. Excluding the impact of compensation related to legacy Series A Interests and Restricted Series C Interests paid for by entities outside of Legence, we generated non-GAAP Adjusted Gross Profit of $169.6 million and non-GAAP Adjusted Gross Margin of 16.1% for the second quarter 2026, compared to non-GAAP Adjusted Gross Profit of $65.2 million and non-GAAP Adjusted Gross Margin of 16.2% for the second quarter 2025. Refer to “Non-GAAP Financial Measures” for definitions of Adjusted Gross Profit and Adjusted Gross Margin and a reconciliation of each to the most directly comparable GAAP measure. The increase in non-GAAP Adjusted Gross Profit was primarily driven by revenue growth, partially offset by a slight decline in non-GAAP Adjusted Gross Margin. The slight decline in non-GAAP Adjusted Gross Margin was primarily due to an increase in Installation & Fabrication revenue mix, and lower service line margins, largely offset by greater economies of scale in customer fulfillment support costs.

Backlog and Awarded Contracts and Book-to-Bill Ratio

Backlog and awarded contracts totaled $5.67 billion at June 30, 2026, an increase of 104.6% from $2.77 billion at June 30, 2025. The consolidated book-to-bill ratio for the three-month period ended June 30, 2026 was 1.2x. Engineering & Consulting segment backlog and awarded contracts increased by 26.6% year over year, primarily from growth in the state & local government, education, and life sciences & healthcare end markets. Installation & Maintenance segment backlog and awarded contracts increased by 141.2% year over year, primarily from the acquisition of Bowers and strong growth in the data centers & technology and education end markets.

Balance Sheet

At June 30, 2026, the Company had cash and equivalents of approximately $292.0 million and total debt⁴ of approximately $1.03 billion. As a result, net leverage was 1.6 times, based on non-GAAP Adjusted EBITDA of the Company for the last 12 months ended June 30, 2026 (“Legence LTM adjusted EBITDA”). When including non-GAAP EBITDA of Bowers for the six months ended December 31, 2025 together with Legence LTM adjusted EBITDA, adjusted net leverage was 1.5 times. Refer to “Non-GAAP Financial Measures” for definitions of net leverage and adjusted net leverage and related reconciliations.

Non-GAAP Financial Measures

In addition to disclosing financial results calculated in accordance with U.S. generally accepted accounting principles (“GAAP”), this press release contains non-GAAP financial measures as described below.

Our non-GAAP financial measures may not be comparable to similarly titled measures used by other companies, have limitations as analytical tools and should not be considered in isolation, or as substitutes for analysis of our operating results as reported under GAAP. Additionally, we do not consider our non-GAAP financial measures superior to, or a substitute for, the equivalent measures calculated and presented in accordance with GAAP.

In addition, this press release includes certain projections of the non-GAAP financial measure Adjusted EBITDA. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliations of the forward-looking non-GAAP financial measures are included.

Revenue Growth (excluding Bowers)

This press release discloses consolidated revenue growth of Legence of 60.0%, and revenue growth of Legence’s Installation & Maintenance segment of 86.6%, for the quarter ended June 30, 2026, compared to the quarter ended June 30, 2025, the calculation of which, in each case, excludes the impact of approximately $303.8 million of second quarter 2026 revenues from Bowers. Such metrics are not calculated in accordance with GAAP. Management believes such metrics provide investors with useful supplemental information regarding the Company’s organic revenue performance by presenting revenue growth without giving effect to the impact of the Bowers acquisition. As calculated in accordance with GAAP, revenue growth of Legence was 110.7% (based on second quarter 2026 and 2025 consolidated revenues of $1.26 billion and $598.9 million, respectively), and revenue growth of Legence’s Installation & Maintenance segment was 162.0% (based on second quarter 2026 and 2025 I&M segment revenues of $1.06 billion and $402.8 million, respectively), for the quarter ended June 30, 2026 compared to the quarter ended June 30, 2025.

Adjusted EBITDA and Adjusted EBITDA Margin; Net Leverage and Adjusted Net Leverage

Adjusted EBITDA and Adjusted EBITDA Margin are financial measures not presented in accordance with GAAP but are intended to provide useful and supplemental information to investors and analysts as they evaluate our performance. Adjusted EBITDA is defined as net loss adjusted to exclude, or otherwise reflect, interest expense, interest income, income tax expense (benefit), depreciation and amortization, credit agreement amendment fees,

12

goodwill impairment, long-lived asset impairment, net gain on sale and disposition of property and equipment, loss on debt extinguishment, acquisition and integration costs, system deployment costs, strategic initiative costs, indemnification asset adjustments, Tax Receivable Agreement liability remeasurements and stock-based and other non-cash compensation expense (benefit). Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by revenue. Adjusted EBITDA and Adjusted EBITDA Margin should not be considered alternatives to net loss or net loss margin, respectively, as determined in accordance with GAAP. Management believes that the exclusion of the above-described items from net loss in the presentation of the non-GAAP measures identified above enables us and our investors to more effectively evaluate our operations period over period and to identify operating trends that might not be apparent due to, among other reasons, the variable nature of these items, both in value and frequency, period over period. In addition, management believes these measures may be useful for investors in comparing our operating results with those of other companies.

Net leverage is defined as net debt of Legence divided by Adjusted EBITDA of Legence, and adjusted net leverage is defined as net debt of Legence divided by LTM combined adjusted EBITDA. Net debt includes total balance sheet debt, excluding finance lease liabilities, less cash and cash equivalents. LTM combined adjusted EBITDA is the sum of (1) adjusted EBITDA of Legence for the 12-month period ended June 30, 2026 (or “Legence LTM adjusted EBITDA”) and (2) EBITDA of Bowers for the six month period ended December 31, 2025 (“Bowers EBITDA”), which is based, in part, on certain unaudited financial information of Bowers for the three months ended December 31, 2025 and audited financial information of Bowers for the year ended September 30, 2025. Bowers EBITDA is defined as net income, plus depreciation and amortization, interest income and income tax expense. The Company believes these non-GAAP measures are useful to investors as they provide alternative information that management believes to be useful in assessing (including, in the case of adjusted net leverage, on a combined basis giving effect to the Bowers acquisition) our ability to meet our payment obligations in addition to considering the absolute amount of our debt.

Adjusted Gross Profit and Adjusted Gross Margin

Adjusted Gross Profit is a financial measure not presented in accordance with GAAP but is intended to provide useful and supplemental information to investors and analysts as they evaluate our performance. Gross profit is defined as revenue less cost of revenue services. Adjusted Gross Profit is defined as gross profit adjusted to exclude

15

compensation related to legacy Series A Interests and Restricted Series C Interests, where the payment of this expense is borne by entities outside of Legence Adjusted Gross Profit should not be considered an alternative to gross profit that is derived in accordance with GAAP. Adjusted Gross Margin is defined as Adjusted Gross Profit divided by revenue. Management believes that the exclusion of the above-described items from gross profit in the presentation of the non-GAAP measure identified above enables us and our investors to supplement the evaluation of our operations period over period and to identify operating trends that might not otherwise be apparent due to, among other reasons, the variable nature of these items, both in value and frequency, period over period. In addition, management believes this measure may be useful for investors in comparing our operating results with those of other companies.

The following table provides a reconciliation of our gross profit, the most directly comparable financial measure presented in accordance with GAAP, to Adjusted Gross Profit for the periods presented herein (in thousands) and our Adjusted Gross Margin for the same periods:

Backlog and Awarded Contracts and Book-to-Bill Ratio

We believe that backlog and awarded contracts and book-to-bill ratio enable us to more effectively forecast our future results and working capital needs, as well as better identify future operating trends that may not otherwise be apparent. Backlog represents, as of any date of determination, the expected revenue values of the remaining performance obligations under our contracted fixed-price projects. Awarded contracts represents, as of any date of determination, the expected revenue values of projects awarded to us following a request for proposals but for which a formal contract has not yet been signed. We calculate our book-to-bill ratio by taking our additions to backlog and awarded contracts, excluding additions that were attained through acquisition, for the period, and dividing it by revenue from fixed-price contracts for the same period. Given that backlog and awarded contracts and book-to-bill ratio are operational measures and that our methodology for calculating each such measure does not meet the definition of a non-GAAP financial measure, as that term is defined by the SEC, a quantitative reconciliation for each is not required or provided.
