VAUGHAN, ON, May 11, 2020 — GFL Environmental Inc. (NYSE: GFL, TSX: GFL) ("GFL" or the "Company") today announced its results for the first quarter of 2020.

"When we completed our initial public offering on March 5 of this year, we never thought we would be reporting our first quarter as a public company in such unprecedented times. Despite the significant slowdown of the Canadian and U.S. economies in late March resulting from government measures to limit the spread of COVID-19, we grew revenue in the quarter by 29.2% and Adjusted EBITDA by 24.4% compared to the first quarter of 2019. Our strong results for the quarter demonstrate the resiliency of our business model" said Patrick Dovigi, Founder and Chief Executive Officer.

"I am very proud of the hard work and commitment of our over 13,000 employees. Without them, we would not have been able to successfully continue to provide our essential services to our customers and communities during these challenging times. Throughout the outbreak of COVID-19 we have remained focused on ensuring the health and safety of our employees."

Mr. Dovigi added "We used the proceeds from our IPO to significantly de-lever our balance sheet. In April we raised US$500 million of 4.25% secured bonds maturing in June 2025, a net leverage neutral financing. Together, these financings have well positioned us to further execute our growth strategy and take advantage of opportunities as they present themselves."

The spread of COVID-19 has created a global health crisis that has resulted in widespread disruption to economic activity in the United States and Canada. The U.S. and Canadian governments as well as numerous state, provincial and local governments have implemented certain measures to attempt to slow and limit the spread of COVID-19, including shelter-in-place and physical distancing orders. The primary impact to our business has been reduced commercial and industrial collection volumes as certain of our customers reduced or suspended their services in response to measures enacted by local authorities. The magnitude of the impacts varied by region and were correlated to the timing and nature of measures enacted. Our primary markets, most notably Toronto and Montreal, were more significantly impacted than the secondary markets we service throughout Canada and the U.S. where we generate almost two thirds of our solid waste revenues.

The health and safety of our employees remain our top priority. In response to the pandemic, we have:

We have also closely managed our operating expenses and capital expenditures by deferring non-essential capital expenditures, reducing variable costs such as overtime, restricting discretionary spending such as travel and postponing merit increases for salaried employees.

The first quarter reflected a partial month's impact of COVID-19 whereas the second quarter is expected to include a full quarter of COVID-19 related impacts. The revenue results for the month of April 2020 reflected a 15.8% increase over April 2019. Excluding the impact of acquisitions and foreign exchange, April 2020 revenue was 9.9% less than April 2019, a decline primarily resulting from reduced commercial and industrial collection volume that we believe is primarily attributable to the general economic impact of COVID-19. Solid waste revenue for the month of April 2020 reflected an 8.7% decline as compared to April 2019, or a 4.2% decline when excluding the Canadian solid waste business which was disproportionately impacted by the shut-down of commercial activity in the provinces of Ontario and Quebec. Over the past several weeks, we have seen sequential increases in commercial and industrial collection activity. Ultimately the total impact of COVID-19 on our business will depend on the timing and extent to which normal economic activity can be restored in the markets in which we operate.

We believe that we are well capitalized and have ample liquidity available to us, including over $700 million in cash at April 30, 2020 and over $600 million available under our revolving credit facility. As a result of the repayment of debt with the proceeds from our initial public offering, we have no material debt maturing over the next five years.

Revenue increased by 29.2% to $931.3 million in the first quarter of 2020 compared to the first quarter of 2019 driven by significant revenue growth across all reportable segments both organically and through acquisitions.

Adjusted EBITDA* increased 24.4% to $222.9 million in the first quarter of 2020 compared to the first quarter of 2019, primarily attributable to strong revenue growth in the quarter. Net loss increased from $93.4 million in the first quarter of 2019 to $277.9 million in the first quarter of 2020 driven by costs associated with our initial public offering, the early redemption of several series of our outstanding unsecured bonds and the extinguishment of our 11% payment-in-kind notes as part of the pre-closing capital changes implemented immediately prior to our initial public offering.

This release includes certain "forward-looking statements", including statements relating to the expected impact of the COVID-19 pandemic on the Company's operations, liquidity and financial results and the Company's ability to execute on its growth strategy. In some cases, but not necessarily in all cases, forward-looking statements can be identified by the use of forward looking terminology such as "plans", "targets", "expects" or "does not expect", "is expected", "an opportunity exists", "is positioned", "estimates", "intends", "assumes", "anticipates" or "does not anticipate" or "believes", or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might", "will" or "will be taken", "occur" or "be achieved". In addition, any statements that refer to expectations, projections or other characterizations of future events or circumstances contain forward-looking statements. Forward-looking statements are not historical facts, nor guarantees or assurances of future performance but instead represent management's current beliefs, expectations, estimates and projections regarding future events and operating performance.

Forward-looking statements are necessarily based on a number of opinions, assumptions and estimates that, while considered reasonable by GFL as of the date of this release, are subject to inherent uncertainties, risks and changes in circumstances that may differ materially from those contemplated by the forward-looking statements. Important factors that could cause actual results to differ, possibly materially, from those indicated by the forward-looking statements include, but are not limited to, the "Risk Factors" section of the Company's final prospectus relating to its initial public offering dated March 2, 2020 and the Company's other periodic filings with the SEC and the securities commissions or similar regulatory authorities in Canada. These factors are not intended to represent a complete list of the factors that could affect GFL. However, such risk factors should be considered carefully. There can be no assurance that such estimates and assumptions will prove to be correct. You should not place undue reliance on forward-looking statements, which speak only as of the date of this release. GFL undertakes no obligation to publicly update any forward-looking statement, except as required by applicable securities laws.

This press 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 or 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.

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, certain expenses, costs, charges or benefits incurred in such period which in management's view are either not indicative of our underlying business performance or impact the ability to assess the operating performance of our business.

Net leverage is a supplemental measure used by management to evaluate the underlying trends in the business and capital allocation strategies. Net leverage is equal to our gross debt, reduced by our cash and cash equivalents, 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 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. 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 the Company would have performed if each of the interim acquisitions 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.

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 (a) give effect to 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 ("Acquisition EBITDA adjustments"), and (b) give effect to contract and acquisition annualization for contracts entered into and acquisitions completed by such acquired business prior to our acquisition. 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. 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 Net Income/Loss represents net income/loss adjusted for (a) amortization of intangibles, (b) the increase in property, plant and equipment depreciation as a result of the recapitalization that occurred on May 31, 2018, (c) the IPO transaction related expenses (d) IPO share based payments, (e) loss on the extinguishment of debt (f) amortization of deferred financing costs (g) loss or gain on the revaluation of the tangible equity units ("TEUs"), (h) foreign exchange loss or gain, (i) acquisition, rebranding and other costs, (j) TEU amortization expense, and (k) the tax impact of the forgoing. Adjusted loss per share is defined as Adjusted Net Income/Loss divided by the weighted average shares in the period. We believe that Adjusted loss per share provides a meaningful comparison of current results to prior periods' results by excluding items that the Company does not believe reflect its fundamental business performance.
