GFL Environmental Inc. (NYSE: GFL) (TSX: GFL) ("GFL", "we" or "our"), a leading North American diversified environmental services company, today announced its results for the third quarter of 2021.

"Our employees continued to deliver exceptional results in the third quarter, allowing us to once again exceed our expectations," said Patrick Dovigi, Founder and Chief Executive Officer of GFL. "This quarter we grew revenue by 43.3%, driven by strong organic growth ahead of expectations and continued outperformance from recent acquisitions. We also expanded Adjusted EBITDA margin¹ by 90 basis points during the quarter, demonstrating the ability to successfully counteract increased inflationary cost pressures through proactive price increases and ongoing efficiency initiatives. We achieved these results in the face of continued COVID-19 restrictions in many of our Canadian markets, where we generate almost 40% of our revenue."

Mr. Dovigi added, "We remain focused on executing on our strategy to create long-term value for all of our stakeholders with the goal of growing our free cash flow. Year-to-date, we completed 37 acquisitions, including the acquisitions of Terrapure Environmental Ltd. and Peoria Disposal Company, further reinforcing our reputation as an acquirer of choice. We also completed several financing initiatives to further reduce our cost of capital, including an amendment to our revolving credit facility, resulting in additional annualized cash interest savings, and an equity commitment of up to US$300.0 million from affiliates of HPS Investment Partners, LLC. Finally, we received an additional US$74.2 million, US$126.4 million year-to-date, from the sale of non-core solid waste assets, the proceeds of which we are actively redeploying into organic and inorganic initiatives in our key growth markets."

Mr. Dovigi continued, "We continue to see upside opportunities ahead of us this year, as a result of our organic initiatives, and the robust M&A pipeline that we manage. Based on our performance to date and our proven ability to deliver on our growth strategies, we are once again increasing our 2021 full year guidance for revenue, Adjusted EBITDA¹ and Adjusted Free Cash Flow¹. Furthermore, excluding acquisitions we expect to complete prior to year-end, we are positioned to have nearly 8.5% of roll over revenue contribution from M&A heading into 2022."

"We remain committed to our sustainability initiatives and continue to evaluate opportunities to unlock what we believe is significant value through landfill gas to energy projects at our MSW landfills and acceleration of the conversion of our fleet to CNG," added Mr. Dovigi. "On October 1, 2021, we expanded on these initiatives with the addition of landfill assets as part of our acquisition of Peoria Disposal Company."

GFL also announced today that Jessica McDonald will be joining the Board of Directors in February 2022.

"Earlier this year we made a commitment to enhance the diversity of our Board of Directors," said Mr. Dovigi. "I am very excited that Jessica has agreed to join our board as our 7^th independent director. Jessica has an extensive background in sustainable initiatives, having previously served as Deputy Minister to the Premier of British Columbia, Strategy Policy, Environment and Resource Development and the President and Chief Executive Officer of BC Hydro and Power Authority. She currently serves as a director and member of the Audit Committee of Hydro One Limited and as a director and member of the Environment, Health, Safety and Corporate Responsibility Committee of Coeur Mining Inc. We welcome Jessica to our board and look forward to working with her."

Third Quarter and Year to Date Results

Revenue increased by 43.3% to $1,485.1 million in the third quarter of 2021 compared to the third quarter of 2020.

Net loss increased to $245.2 million in the third quarter of 2021 compared to a net loss of $114.7 million in the third quarter of 2020. Cash flows from operating activities decreased by 12.8% to $223.9 million in the third quarter of 2021 compared to the third quarter of 2020.

Financial Impact from COVID-19

Since the outbreak of the COVID-19 pandemic in March 2020, the U.S. and Canadian governments, as well as numerous state, provincial and local governments, implemented certain measures to slow the spread of the virus, including shelter-in-place and physical distancing orders as well as closure restrictions or requirements. In the first half of 2021, we saw these measures lifted or scaled back in many U.S. states resulting in an accelerated economic recovery. In Canada, many provincial governments introduced new increased measures and re-introduced former measures, resulting in a slower recovery. Some of these restrictions began to ease towards the end of the second quarter of 2021, however, a resurgence of cases in certain provinces during the third quarter resulted in the re-introduction of former measures or provinces maintaining their existing measures. The impact of the COVID-19 pandemic on our business and future results of operations, financial condition and cash flows will depend largely on future developments, which are uncertain and continue to evolve, including the duration and spread of the virus in Canada and the United States, the continued roll-out, execution and effectiveness of vaccination programs, the severity of and actions taken to limit the spread of COVID-19, including variants, and the pace and extent to which normal economic and operating conditions resume in the markets that we serve.

Updated Full Year 2021 Guidance²

GFL also provided its updated guidance for 2021 assuming a CAD/US exchange rate of 1.25 for the remainder of the year (as compared to the guidance provided on July 28, 2021):

• Revenue is estimated to be between $5,390 million and $5,410 million (as compared to between $5,225 million and $5,275 million)
• Adjusted EBITDA is estimated to be between $1,440 million and $1,450 million (as compared to between $1,400 million and $1,415 million)
• Adjusted Free Cash Flow is estimated to be between $525 million and $530 million (as compared to between $510 and $520 million)

In addition, net capital expenditures for 2021 are expected to be approximately $540 million and non-acquisition related investment in working capital is estimated to be $35 million.

The 2021 updated guidance includes the expected contribution of acquisitions already completed in 2021 but excludes any impact from additional acquisitions not yet completed, refinancing opportunities and any potential redeployment of capital. Implicit in forward-looking statements in respect of our expectations for 2021 are certain current assumptions, including, among others, no changes to the current economic environment and that none of the jurisdictions in which we operate institute additional COVID-19 measures including shelter-in-place or similar orders. The 2021 updated guidance assumes that we will continue to execute on our strategy of organically growing our business, leveraging our scalable network to attract and retain customers across multiple service lines, realize operational efficiencies, and extract procurement and cost synergies.

Forward-looking statements may relate to our future outlook, financial guidance and anticipated events or results and may include statements regarding our financial performance, financial condition or results, business strategy, growth strategies, budgets, operations and services. Particularly, statements regarding our expectations of future results, performance, achievements, prospects or opportunities or the markets in which we operate is forward-looking statements. In some 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", "budget", "scheduled", "estimates", "outlook", "forecasts", "projection", "prospects", "strategy", "intends", "anticipates", "does not anticipate", "believes", or "potential" or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might", "will", "will be taken", "occur" or "be achieved". In addition, any statements that refer to expectations, intentions, projections, potential or other characterizations of future events or circumstances contain forward-looking information. Statements containing forward-looking information are not historical facts nor assurances of future performance but instead represent management's expectations, estimates and projections regarding future events or circumstances.

These forward-looking statements and other forward-looking information are based on our opinions, estimates and assumptions in light of our experience, track record, perception of historical trends, current conditions, growth opportunities and expected future developments, as well as other factors that we currently believe are appropriate and reasonable in the circumstances. Certain assumptions are set out herein in the section titled "Updated Full Year 2021 Guidance" and also include our ability to obtain and maintain existing financing on acceptable terms; our ability to source and execute on acquisitions on terms acceptable to us; our ability to find purchasers for non-core assets on terms acceptable to us; currency exchange and interest rates; the impact of competition; the changes and trends in our industry or the global economy; and the changes in laws, rules, regulations, and global standards, are material factors considered in preparing forward-looking statements and management's expectations. Other factors that could materially affect our forward-looking statements can be found in the "Risk Factors" section of GFL's annual report for the 2020 fiscal year filed on Form 20-F and GFL's other periodic filings with the U.S. Securities and Exchange Commission and the securities commissions or similar regulatory authorities in Canada. Shareholders, potential investors and other readers are urged to consider these risks carefully in evaluating our forward-looking statements and are cautioned not to place undue reliance on such statements.

There can be no assurance that the underlying opinions, estimates and assumptions will prove to be correct. In particular, it is difficult to predict the duration and severity of the COVID-19 pandemic, including variants, and its impact on the economy, the North American financial markets, our operations, our M&A pipeline and our financial results. Although we have attempted to identify important risk factors that could cause actual results to differ materially from those contained in forward-looking information, there may be other factors not presently known to us or that we presently believe are not material that could also cause actual results or future events to differ materially from those expressed in such forward-looking information. There can be no assurance that such information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such information. Accordingly, readers should not place undue reliance on forward-looking information, which speaks only as of the date made. The forward-looking information contained in this release represents our expectations as of the date of this release (or as the date they are otherwise stated to be made), and are subject to change after such date. However, we disclaim any intention or obligation or undertaking to update or revise any forward-looking information whether as a result of new information, future events or otherwise, except as required under applicable U.S. or Canadian securities laws. The purpose of disclosing our financial outlook set out in this release is to provide investors with more information concerning the financial impact of our business initiatives and growth strategies.

Non-IFRS Measures

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.

In addition, GFL's projected full year 2021 Adjusted EBITDA and Adjusted Free Cash Flow are anticipated to exclude the effects of other events or circumstances in 2021 that are not representative or indicative of GFL's results of operations. Such excluded items are not currently determinable, but may be significant, such as changes in the foreign exchange rate, the mark-to-market (gain) loss on the Purchase Contracts, the cost of refinancings and acquisition, integration, rebranding and other costs. Due to the uncertainty of the likelihood, amount and timing of any such items, GFL does not have information available to provide a quantitative reconciliation of such projections to the comparable IFRS measure.

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 fuel hedges, (d) mark-to-market (gain) loss on Purchase Contracts, (e) share-based payments, (f) gain on divestiture, (g) transaction costs, (h) IPO transaction costs, (i) acquisition, rebranding and other integration costs (included in cost of sales related to acquisition activity), and (j) deferred purchase consideration. We use Adjusted EBITDA to facilitate a comparison of our operating performance on a consistent basis reflecting factors and trends affecting our business.

Adjusted EBITDA margin represents Adjusted EBITDA divided by revenue. We 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 ("Acquisition EBITDA Adjustments"), and (b) 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 Cash Flows from Operating Activities represents cash flows from operating activities adjusted for (a) costs associated with IPO related debt repayments, (b) prepayment penalties for early note redemption, (c) IPO transaction costs, (d) transaction costs, (e) acquisition, rebranding and other integration costs, (f) M&A related net working capital investment, (g) tax refund from CARES Act, (h) deferred purchase consideration, and (i) cash interest paid on TEUs. Adjusted Free Cash Flow represents Adjusted Cash Flows from Operating Activities adjusted for (a) proceeds from asset divestitures, (b) proceeds on disposal of assets and (c) purchase of property and equipment and intangible assets. Adjusted Cash Flows from Operating Activities and Adjusted Free Cash Flow are supplemental measures used by investors as a valuation and liquidity measure in our industry. Management uses Adjusted Cash Flows from Operating Activities and Adjusted Free Cash Flow to evaluate and monitor the ongoing financial performance of GFL.

Adjusted Net Income (Loss) represents net income (loss) adjusted for (a) amortization of intangible assets, (b) ARO discount rate depreciation adjustment, (c) incremental depreciation of property and equipment due to recapitalization, (d) IPO transaction costs, (e) loss on extinguishment of debt, (f) amortization of deferred financing costs (g) mark-to-market (gain) loss on Purchase Contracts, (h) gain on divestiture, (i) (gain) loss on foreign exchange, (j) transaction costs, (k) acquisition, rebranding and other integration costs, (l) TEU amortization expense, and (m) the tax impact of the forgoing. Adjusted earnings (loss) per share is defined as Adjusted Net Income (Loss) divided by the weighted average shares in the period. We believe that Adjusted earnings (loss) per share provides a meaningful comparison of current results to prior periods' results by excluding items that GFL does not believe reflect its fundamental business performance.

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. 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 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. Run-Rate EBITDA as presented herein is calculated in accordance with the terms of our revolving credit agreement.
