Exhibit 99.1

WASTE CONNECTIONS REPORTS SECOND QUARTER 2025 RESULTS AND

UPDATES FULL YEAR OUTLOOK

Continued improvement in employee retention and record safety performance complement 6.6% solid waste core pricing to drive better than expected results

Revenue of $2.407 billion, above expectations and up 7.1%

Net income^(a) of $290.3 million, or $1.12 per share, adjusted net income attributable to Waste Connections^(b) of $333.1 million, or $1.29 per share

Adjusted EBITDA^(b) of $786.4 million, above expectations and up 7.5%

Adjusted EBITDA^(b) margin of 32.7% of revenue

Maintains full year 2025 outlook of $9.45 billion in revenue, $3.12 billion in adjusted EBITDA^(b) and $1.30 billion in adjusted free cash flow^(b)

TORONTO, ONTARIO, July 23, 2025 - Waste Connections, Inc. (TSX/NYSE: WCN) (“Waste Connections” or the “Company”) today announced its results for the second quarter of 2025 and updated its outlook for the full year.

“Continued improvement in employee retention and record low safety rates, along with solid waste core pricing growth of 6.6%, drove underlying solid waste margin expansion of approximately 70 basis points in the period,” said Ronald J. Mittelstaedt, President and Chief Executive Officer. “We delivered results above our outlook for the quarter in spite of headwinds from lower-than-expected contributions from higher margin, commodity-related activities and continued sluggishness in the economy, along with tariff-induced uncertainties.”

“As anticipated, we have already completed an outsized year of acquisition activity, at approximately $200 million in annualized revenue, with a robust pipeline and almost half of the year still ahead of us. The strength of our financial profile and free cash flow generation keeps us well-positioned for additional acquisitions, while maintaining the flexibility for increased return of capital to shareholders, including through opportunistic share repurchases already underway.”

Mr. Mittelstaedt added, “In spite of incremental and growing headwinds, our full year 2025 outlook remains within the ranges from February, providing for approximately 6% revenue growth and 50 basis points of adjusted EBITDA margin expansion to 33.0%. We remain well-positioned for upside from contributions from additional acquisitions, improvements in commodity-related activity and solid waste volumes.”

Q2 2025 Results

Revenue in the second quarter totaled $2.407 billion, up from $2.248 billion in the year ago period. Operating income was $459.5 million, which included $7.3 million primarily in impairments and other operating items and transaction-related expenses. This compares to operating income of $424.7 million in the second quarter of 2024, which included $15.7 million primarily in impairments and other operating items and transaction-related expenses. Net income in the second quarter was $290.3 million, or $1.12 per share on a diluted basis of 259.0 million shares. In the year ago period, the Company reported net income of $275.5 million, or $1.07 per share on a diluted basis of 258.6 million shares.

Adjusted net income^(b) in the second quarter was $333.1 million, or $1.29 per diluted share, versus $320.0 million, or $1.24 per diluted share, in the prior year period. Adjusted EBITDA^(b) in the second quarter was $786.4 million, as compared to $731.8 million in the prior year period. Adjusted net income, adjusted net income per diluted share and adjusted EBITDA, all non-GAAP measures, primarily exclude impairments and acquisition-related items, as reflected in the detailed reconciliations in the attached tables.

NON-GAAP RECONCILIATION SCHEDULE

(in thousands of U.S. dollars, except where noted)

Reconciliation of Adjusted EBITDA:

Adjusted EBITDA, a non-GAAP financial measure, is provided supplementally because it is widely used by investors as a performance and valuation measure in the solid waste industry. Management uses adjusted EBITDA as one of the principal measures to evaluate and monitor the ongoing financial performance of Waste Connections’ operations. Waste Connections defines adjusted EBITDA as net income attributable to Waste Connections, plus or minus net income (loss) attributable to noncontrolling interests, plus income tax provision, plus interest expense, less interest income, plus depreciation and amortization expense, plus closure and post-closure accretion expense, plus or minus any loss or gain on impairments and other operating items, plus other expense, less other income. Waste Connections further adjusts this calculation to exclude the effects of other items management believes impact the ability to assess the operating performance of its business. This measure is not a substitute for, and should be used in conjunction with, GAAP financial measures. Other companies may calculate adjusted EBITDA differently.

(in thousands of U.S. dollars, except where noted)

Reconciliation of Adjusted Free Cash Flow:

Adjusted free cash flow, a non-GAAP financial measure, is provided supplementally because it is widely used by investors as a liquidity measure in the solid waste industry. Waste Connections calculates adjusted free cash flow as net cash provided by operating activities, plus or minus change in book overdraft, plus proceeds from disposal of assets, less capital expenditures for property and equipment. Waste Connections further adjusts this calculation to exclude the effects of items management believes impact the ability to evaluate the liquidity of its business operations. This measure is not a substitute for, and should be used in conjunction with, GAAP liquidity or financial measures. Other companies may calculate adjusted free cash flow differently.

NON-GAAP RECONCILIATION SCHEDULE (continued)

(in thousands of U.S. dollars, except per share amounts)

Reconciliation of Adjusted Net Income attributable to Waste Connections and Adjusted Net Income per Diluted Share attributable to Waste Connections:

Adjusted net income attributable to Waste Connections and adjusted net income per diluted share attributable to Waste Connections, both non-GAAP financial measures, are provided supplementally because they are widely used by investors as valuation measures in the solid waste industry. Management uses adjusted net income attributable to Waste Connections and adjusted net income per diluted share attributable to Waste Connections as one of the principal measures to evaluate and monitor the ongoing financial performance of Waste Connections’ operations. Waste Connections provides adjusted net income attributable to Waste Connections to exclude the effects of items management believes impact the comparability of operating results between periods. Adjusted net income attributable to Waste Connections has limitations due to the fact that it excludes items that have an impact on the Company’s financial condition and results of operations. Adjusted net income attributable to Waste Connections and adjusted net income per diluted share attributable to Waste Connections are not a substitute for, and should be used in conjunction with, GAAP financial measures. Other companies may calculate these non-GAAP financial measures differently.
