Exhibit 99.1

WASTE CONNECTIONS REPORTS FIRST QUARTER 2026 RESULTS

- Better than expected Q1 results, with improving trends positioning for upside to 2026 outlook

- Revenue of $2.371 billion, above expectations and up 6.4% year over year

- Net income of $219.3 million and adjusted EBITDA(a) of $769.5 million, above expectations and up 8.0% year over year

- Adjusted EBITDA margin(a) of 32.5%, above expectations and up 50 basis points year over year

- Net income and adjusted net income(a) per share of $0.86 and $1.23, respectively

- Year-to-date share repurchases of 1% of outstanding shares

TORONTO, ONTARIO, April 22, 2026 - Waste Connections, Inc. (TSX/NYSE: WCN) (“Waste Connections” or the “Company”) today announced its results for the first quarter of 2026.

“We’re extremely pleased by the strong start to 2026 and remain well-positioned for the full year, with upside potential from commodity-related impacts, solid waste organic growth and additional acquisitions. On revenue and adjusted EBITDA above our expectations, we delivered adjusted EBITDA(a) margin of 32.5% in spite of outsized weather events and in advance of recovering higher fuel costs,” said Ronald J. Mittelstaedt, President and Chief Executive Officer.

“In spite of geopolitical instability, our results reflect consistency of execution as we continue to benefit from operating momentum from improved employee engagement, with safety performance at record levels and voluntary turnover now below 10%,” continued Mr. Mittelstaedt. “Moreover, we should be well-positioned for incremental benefits from higher fuel and other commodities, as well as strong pricing retention and increased special waste activity, and also longer term as a result of our expanding use of A.I. through technology-related investments.”

Mr. Mittelstaedt concluded, “Finally, we continue to anticipate another outsized year of acquisition activity, given a robust pipeline, along with increasing return of capital to shareholders, including year-to-date share repurchases of over $360 million or approximately 1% of shares outstanding.”

Q1 2026 Results

Revenue in the first quarter totaled $2.371 billion, up from $2.228 billion in the prior year period. Operating income was $364.1 million, which included $80.4 million primarily in impairments related to adjustments to landfill closure and post closure costs. This compares to operating income of $390.2 million in the prior year period, which included $20.2 million primarily in transaction-related expenses, impairments and other operating items and fair value accounting changes associated with certain equity awards. Net income in the first quarter was $219.3 million, or $0.86 per share on a diluted basis of 255.9 million shares. In the prior year period, the Company reported net income of $241.5 million, or $0.93 per share on a diluted basis of 258.9 million shares.

Adjusted net income(a) in the first quarter was $314.9 million, or $1.23 per diluted share, up from $293.1 million, or $1.13 per diluted share, in the prior year period. Adjusted EBITDA(a) in the first quarter was $769.5 million, up from $712.2 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 transaction-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, 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.

NON-GAAP RECONCILIATION SCHEDULE (continued)

(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 and Adjusted Net Income per Diluted Share:

Adjusted net income and adjusted net income per diluted share, 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 and adjusted net income per diluted share as one of the principal measures to evaluate and monitor the ongoing financial performance of Waste Connections’ operations. Waste Connections provides adjusted net income to exclude the effects of items management believes impact the comparability of operating results between periods. Adjusted net income 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 and adjusted net income per diluted share 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.
