GFL Environmental Inc. Announces Commencement of Share Repurchase Program

VAUGHAN, ON, February 27, 2025 – GFL Environmental Inc. (NYSE: GFL) (TSX: GFL) (“GFL” or the “Company”) today announced that the Toronto Stock Exchange (“TSX”) has accepted the Company’s notice of intention to commence a normal course issuer bid (the “NCIB”) for the 12-month period commencing on March 3, 2025 and ending no later than March 2, 2026. The NCIB will be conducted through the facilities of the TSX and the New York Stock Exchange (“NYSE”) or alternative Canadian and U.S. trading systems, if eligible.

The NCIB only relates to subordinate voting shares, of which GFL had 381,570,455 subordinate voting shares issued and outstanding as of February 18, 2025. Under the NCIB, a maximum of 28,046,256 subordinate voting shares (representing 10% of the public float (the “Public Float”) determined in accordance with TSX requirements as at February 18, 2025) may be repurchased by GFL. All subordinate voting shares repurchased by GFL under the NCIB will be cancelled.

“On January 7, 2025, we announced the sale of our Environmental Services businesses which we expect to close effective March 1, 2025,” said Patrick Dovigi, Founder and CEO of GFL. “We have allocated up to $2.25 billion of the net proceeds from the transaction to opportunistically repurchase our subordinate voting shares. We expect to use the majority of these proceeds to purchase shares held by our sponsor shareholders, with the balance to be used for open market purchases under our normal course issuer bid.”

Purchases under the NCIB may be made by means of open market transactions, including through an automatic share purchase plan, privately negotiated transactions or such other means as a securities regulatory authority may permit. In accordance with TSX rules, any daily repurchases would be limited to a maximum of 64,492 subordinate voting shares, which represents 25% of the average daily trading volume on the TSX of 257,968 subordinate voting shares for the period from August 1, 2024 to January 31, 2025. The TSX rules also allow the Company to purchase, once a week, a block of subordinate voting shares not owned by any insiders, which may exceed such daily limit. The specific method, timing, price and size of purchases will depend on prevailing stock prices, general economic and market conditions, and other considerations.

Pursuant to exemptive relief granted by the Ontario Securities Commission (“OSC”) to the Company on February 26, 2025, GFL is allowed to purchase up to 10% of its Public Float through the facilities of the NYSE and other U.S.-based trading systems as part of any NCIB implemented in the 36 months following the date of the decision, and will therefore not be limited on such trading platforms to purchasing 5% of its outstanding subordinate voting shares at the beginning of any 12-month period as Canadian securities laws would otherwise provide. A copy of the decision from the OSC has been filed under GFL’s SEDAR+ profile at www.sedarplus.ca.

Subject to receiving exemptive relief from applicable securities regulatory authorities, GFL may also acquire subordinate voting shares through privately negotiated transactions. GFL expects that any private purchase made under an exemption order issued by a securities regulatory authority would be at a discount to the prevailing market price.

Under GFL’s NCIB for the 12-month period that began on May 12, 2023 and ended on May 11, 2024, GFL was authorized to repurchase up to 17,867,120 subordinate voting shares, or 5% of its then issued and outstanding subordinate voting shares. No subordinate voting shares were repurchased thereunder.

The NCIB does not obligate GFL to acquire a specific dollar amount or number of shares and may be extended, modified, or discontinued at any time at the Company’s discretion.

Non-IFRS Measures

This release makes reference to certain non-IFRS measures. These measures are not recognized measures under IFRS and do not have a standardized meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other companies. Accordingly, these measures should not be considered in isolation nor as a substitute for analysis of our financial information reported under IFRS. Rather, these non-IFRS measures are used to provide investors with supplemental measures of our operating performance and thus highlight trends in our core business that may not otherwise be apparent when relying solely on IFRS measures. We also believe that securities analysts, investors and other interested parties frequently use non-IFRS measures in the evaluation of issuers. Our management also uses non-IFRS measures in order to facilitate operating performance comparisons from period to period, to prepare annual operating budgets and forecasts and to determine components of management compensation.

EBITDA represents, for the applicable period, net income (loss) plus (a) interest and other finance costs, plus (b) depreciation and amortization of property and equipment, landfill assets and intangible assets, plus (less) (c) the provision (recovery) for income taxes, in each case to the extent deducted or added to/from net income (loss). We present EBITDA to assist readers in understanding the mathematical development of Adjusted EBITDA. Management does not use EBITDA as a financial performance metric.

Adjusted EBITDA is a supplemental measure used by management and other users of our financial statements including, our lenders and investors, to assess the financial performance of our business without regard to financing methods or capital structure. Adjusted EBITDA is also a key metric that management uses prior to execution of any strategic investing or financing opportunity. For example, management uses Adjusted EBITDA as a measure in determining the value of acquisitions, expansion opportunities, and dispositions. In addition, Adjusted EBITDA is utilized by financial institutions to measure borrowing capacity. Adjusted EBITDA is calculated by adding and deducting, as applicable from EBITDA, certain expenses, costs, charges or benefits incurred in such period which in management's view are either not indicative of underlying business performance or impact the ability to assess the operating performance of our business, including: (a) (gain) loss on foreign exchange, (b) (gain) loss on sale of property and equipment, (c) mark-to-market (gain) loss on Purchase Contracts, (d) share of net (income) loss of investments accounted for using the equity method for associates, (e) share-based payments, (f) (gain) loss on divestiture, (g) transaction costs, (h) acquisition, rebranding and other integration costs (included in cost of sales related to acquisition activity), (i) Founder/CEO remuneration and (j) other. We use Adjusted EBITDA to facilitate a comparison of our operating performance on a consistent basis reflecting factors and trends affecting our business. As we continue to grow our business, we may be faced with new events or circumstances that are not indicative of our underlying business performance or that impact the ability to assess our operating performance.

Adjusted EBITDA margin represents Adjusted EBITDA divided by revenue. Management and other users of our financial statements including our lenders and investors use Adjusted EBITDA margin to facilitate a comparison of the operating performance of each of our operating segments on a consistent basis reflecting factors and trends affecting our business.

Acquisition EBITDA represents, for the applicable period, management's estimates of the annual Adjusted EBITDA of an acquired business, based on its most recently available historical financial information at the time of acquisition, as adjusted to give effect to (a) the elimination of expenses related to the prior owners and certain other costs and expenses that are not indicative of the underlying business performance, if any, as if such business had been acquired on the first day of such period and (b) contract and acquisition annualization for contracts entered into and acquisitions completed by such acquired business prior to our acquisition (collectively, "Acquisition EBITDA Adjustments"). Further adjustments are made to such annual Adjusted EBITDA to reflect estimated operating cost savings and synergies, if any, anticipated to be realized upon acquisition and integration of the business into our operations. Acquisition EBITDA is calculated net of divestitures. We use Acquisition EBITDA for the acquired businesses to adjust our Adjusted EBITDA to include a proportional amount of the Acquisition EBITDA of the acquired businesses based upon the respective number of months of operation for such period prior to the date of our acquisition of each such business.

Adjusted Cash Flows from Operating Activities represents cash flows from operating activities adjusted for (a) transaction costs, (b) acquisition, rebranding and other integration costs, (c) Founder/CEO remuneration, (d) cash interest paid on TEUs, (e) cash taxes related to divestitures and (f) distribution received from joint ventures. Adjusted Cash Flows from Operating Activities is a supplemental measure used by investors as a valuation and liquidity measure in our industry and is used by management to evaluate and monitor liquidity and the ongoing financial performance of GFL.

Adjusted Free Cash Flow represents Adjusted Cash Flows from Operating Activities adjusted for (a) proceeds on disposal of assets and other, (b) purchase of property and equipment and (c) incremental growth investments. Adjusted Free Cash Flow is a supplemental measure used by investors as a valuation and liquidity measure in our industry. Adjusted Free Cash Flow is a supplemental measure used by management to evaluate and monitor liquidity and the ongoing financial performance of GFL.

Net Leverage is a supplemental measure used by management to evaluate borrowing capacity and capital allocation strategies. Net Leverage is equal to our total long-term debt, as adjusted for fair value, deferred financings and other adjustments and reduced by our cash, divided by Run-Rate EBITDA.

Run-Rate EBITDA represents Adjusted EBITDA for the applicable period as adjusted to give effect to management's estimates of (a) Acquisition EBITDA Adjustments (as defined above) and (b) the impact of annualization of certain new municipal and disposal contracts and cost savings initiatives, entered into, commenced or implemented, as applicable, in such period, as if such contracts or costs savings initiatives had been entered into, commenced or implemented, as applicable, on the first day of such period ((a) and (b), collectively, "Run-Rate EBITDA Adjustments"). Run-Rate EBITDA has not been adjusted to take into account the impact of the cancellation of contracts and cost increases associated with these contracts. These adjustments reflect monthly allocations of Acquisition EBITDA for the acquired businesses based on straight line proration. As a result, these estimates do not take into account the seasonality of a particular acquired business. While we do not believe the seasonality of any one acquired business is material when aggregated with other acquired businesses, the estimates may result in a higher or lower adjustment to our Run-Rate EBITDA than would have resulted had we adjusted for the actual results of each of the acquired businesses for the period prior to our acquisition. We primarily use Run-Rate EBITDA to show how GFL would have performed if each of the acquired businesses had been consummated at the start of the period as well as to show the impact of the annualization of certain new municipal and disposal contracts and cost savings initiatives. We also believe that Run-Rate EBITDA is useful to investors and creditors to monitor and evaluate our borrowing capacity and compliance with certain of our debt covenants. Run-Rate EBITDA as presented herein is calculated in accordance with the terms of our revolving credit agreement.
