“Our solid results in the second quarter reflect our continued focus on disciplined pricing and cost optimization across our business,” said Jim Fish, WM’s President and Chief Executive Officer. “This focus delivered a 60-basis-point expansion in adjusted operating EBITDA margin in the quarter, driven by the collection and disposal business and strong SG&A cost control.”^(a)

Fish continued, “Our teams have executed well during the first half of 2023, delivering solid results despite persistent inflation in many cost categories, lower-than-anticipated renewable energy prices, and slower-than-planned event-driven volumes. Considering these market-driven impacts and Hurricane Ian clean-up volumes that were significantly lower than expected, we are well positioned to deliver strong growth in the back half of the year as these pressures abate. We are pleased that our disciplined pricing is keeping pace with rising costs, we are achieving meaningful improvements in frontline turnover, and we are driving leverage on the SG&A expense line. Our teams also continue to execute on our sustainability growth strategy, as three sustainability growth projects came online during the quarter.”

REVISED 2023 OUTLOOK

With half of the year complete, the Company is updating its full-year outlook to modestly adjust its expectations for 2023. The revised financial outlook considers first half results relative to plan as well as a change in outlook for the second half of the year primarily due to expectations for slower recycled commodity price recovery and lower event-driven volumes.

to a delay in the timing of certain construction projects. Free cash flow excluding targeted sustainability growth investments is expected to be between $2.575 and $2.675 billion, essentially in line with prior guidance.^(a)

“As we move into the back half of 2023, we remain focused on cost optimization, efficiency improvements, and solid execution on pricing to overcome top-line pressures from lower recycling commodity prices and slower than expected event-driven volumes. We expect this focus to continue to translate into strong margin expansion,” Fish concluded.

Non-GAAP Financial Measures

To supplement its financial information, the Company has presented, and/or may discuss on the conference call, adjusted earnings per diluted share, adjusted net income, adjusted income from operations, adjusted operating EBITDA, adjusted operating EBITDA margin, adjusted operating expenses, adjusted SG&A expenses, and free cash flow, as well as projections of adjusted operating EBITDA and free cash flow. All of these items are non-GAAP financial measures, as defined in Regulation G of the Securities Exchange Act of 1934, as amended. The Company reports its financial results in compliance with GAAP but believes that also discussing non-GAAP measures provides investors with (i) financial measures the Company uses in the management of its business and (ii) additional, meaningful comparisons of current results to prior periods’ results by excluding items that the Company does not believe reflect its fundamental business performance and are not representative or indicative of its results of operations.

In addition, the Company’s projected future operating EBITDA is anticipated to exclude the effects of other events or circumstances that are not representative or indicative of the Company’s results of operations. Such excluded items are not currently determinable, but may be significant, such as asset impairments and one-time items, charges, gains or losses from divestitures or litigation, and other items. Due to the uncertainty of the likelihood, amount and timing of any such items, the Company does not have information available to provide a quantitative reconciliation of such projection to the comparable GAAP measure.

The Company discusses free cash flow and provides a projection of free cash flow because the Company believes that it is indicative of its ability to pay its quarterly dividends, repurchase common stock, fund acquisitions and other investments and, in the absence of refinancings, to repay its debt obligations. Free cash flow is not intended to replace “Net cash provided by operating activities,” which is the most comparable GAAP measure. The Company believes free cash flow gives investors useful insight into how the Company views its liquidity, but the use of free cash flow as a liquidity measure has material limitations because it excludes certain expenditures that are required or that the Company has committed to, such as declared dividend payments and debt service requirements. The Company defines free cash flow as net cash provided by operating activities, less capital expenditures, plus proceeds from divestitures of businesses and other assets (net of cash divested); this definition may not be comparable to similarly-titled measures reported by other companies.

The quantitative reconciliations of non-GAAP measures to the most comparable GAAP measures are included in the accompanying schedules, with the exception of projected adjusted operating EBITDA. Non-GAAP measures should not be considered a substitute for financial measures presented in accordance with GAAP.
