Waste Management picks up trash, runs it through a network of transfer stations, and buries or processes it at one of 257 landfills across the United States and Canada. Customers pay on long-term contracts, usually three to ten years, so the revenue arrives whether the economy is booming or shrinking. The company also captures the methane gas that rotting garbage produces, converts it into renewable natural gas and electricity, and sells that energy back to utilities and industrial customers. In 2024 it added a new arm by acquiring Stericycle, which collects medical waste from hospitals and shreds confidential documents for businesses across North America and Western Europe. Four income streams, one underlying fact: people generate waste every single day, and someone has to deal with it. The diagram below traces where the money goes.

Five years of financial data tell a consistent story. Revenue has climbed every single year, from $17.9 billion in 2021 to $25.2 billion in 2025. A big piece of that 2025 jump came from the Stericycle acquisition closing in late 2024, which added a full year of healthcare waste revenue in 2025. But organic growth was real too: the core collection and disposal business raised prices steadily, and landfill volumes grew, partly helped by wildfire cleanup work in the Western United States.
Annual Revenue 2021 to 2025 ($B)
Revenue has grown every year for five consecutive years, reaching $25.2B in 2025.
Gross margin has also improved each year, moving from 38.0% in 2021 to 40.4% in 2025. That means the company is keeping more of each dollar it collects, not just collecting more dollars. Operating cash flow followed the same path, rising from $4.3 billion in 2021 to $6.0 billion in 2025. That cash funds dividends, debt repayment, and the heavy capital spending needed to build new recycling facilities and renewable energy projects.

Operating cash flow in 2025, up from $4.3B in 2021
Free cash flow, which is what is left after the company pays for its physical assets, dipped in 2022 and 2023 as the company spent heavily building out recycling automation and renewable energy infrastructure. It recovered to $2.8 billion in 2025 as those construction projects wrapped up and started generating returns. The company described this as moving from a peak construction period into a harvest period.
What is net debt?
Net debt is how much a company owes to lenders after subtracting the cash it holds. A rising net debt number means the company borrowed more than it paid back. It is not automatically bad if the borrowed money funds assets that generate income, but it does mean more of the company's future cash flow must go toward interest payments rather than other uses.
The one clear negative in the five-year picture is debt. Net debt sat at $13.3 billion in 2021 and climbed steadily, then jumped sharply to $23.5 billion in 2024 when the company borrowed heavily to fund the $7.2 billion Stericycle acquisition. It edged down slightly to $22.7 billion by the end of 2025. Management said it resumed share repurchases in early 2026 only because leverage was already declining, which suggests the priority remains debt reduction for now.
The Stericycle acquisition nearly doubled net debt in three years. It began declining in 2025, reaching $22.7B.
2024
milestone
Stericycle Acquisition
In November 2024, Waste Management paid $62.00 per share in cash to acquire Stericycle, with a total enterprise value of $7.2 billion. The deal added medical waste collection and secure document shredding across the United States, Canada, and parts of Western Europe. It also added significant debt and integration costs: the company spent $160 million on acquisition and integration costs in 2024 alone, and another $120 million in 2025.
The risks worth watching are specific, not generic. First, Stericycle itself. Paying $7.2 billion for a business and then having to spend hundreds of millions more just to make it run properly is a live risk. If the company cannot get Stericycle's costs under control or loses key healthcare customers during the messy integration process, the financial case for that acquisition weakens.
Second, landfill permits. Waste Management owns the largest landfill network in North America, and that network is the core of its pricing power. But permits to build or expand landfills take years to obtain and face fierce community opposition. If the company cannot get the permits it needs to expand capacity, it loses the ability to accept more waste and must send overflow to more expensive third-party sites.
What are PFAS chemicals?
PFAS stands for per- and polyfluoroalkyl substances, sometimes called forever chemicals because they do not break down naturally. They show up in many everyday products and can leach into soil and groundwater at landfills. New government rules require landfill operators to test for and manage PFAS contamination, which adds cost. The full scope of future PFAS rules is still being written.
Third, recycling commodity prices. The company processed more recyclable material than ever in 2025, but average market prices for single-stream recycled commodities fell roughly 20% compared to 2024. That caused a $166 million revenue drop just from price changes in that one segment. The company has been shifting customers to a fee-for-service model to reduce this exposure, but the shift is not complete, and future price swings could still move the earnings needle.

Revenue lost in 2025 from falling recycled commodity prices alone
Fourth, the truck fleet. The company spent heavily converting its collection trucks to run on natural gas, and built fueling stations to support them. Regulators are now pushing toward electric vehicles instead. If electric vehicle mandates accelerate, the natural gas infrastructure the company already paid for becomes a stranded cost, and the company faces enormous new spending on electric trucks and charging stations before the old investment has fully paid back.
Waste Management has raised its quarterly dividend for 23 consecutive years. In December 2025, the board signaled a 14.5% increase for 2026, from $0.825 to $0.945 per share. That streak reflects the stability of the underlying cash flows, but it also means a growing fixed cash obligation regardless of what happens to commodity prices or integration costs.
The Bet
Waste Management assumes that Stericycle can be integrated cleanly enough, and quickly enough, to justify the nearly $7.2 billion paid and the near-doubling of net debt that funded the deal. The medical waste business has to grow into its purchase price while the core landfill and collection business continues generating the cash needed to pay down debt, fund dividends, and invest in recycling automation and renewable energy projects all at the same time. If Stericycle integration takes longer or costs more than planned, or if a recession cuts waste volumes at the same time, the company would be managing a large debt load with less cash to service it than the current trajectory assumes.
Open question
The core garbage business is steady, the cash flows are large, and the dividend record is long. But the company is now carrying more than twice the debt it had four years ago, integration costs are still running into the hundreds of millions, and recycling and renewable energy revenues swing with commodity markets that no one fully controls. Can Waste Management digest a $7.2 billion acquisition while simultaneously paying down debt, raising dividends, and funding the next generation of recycling and energy infrastructure, without any of those plates dropping if the economy softens or commodity prices fall further?

Stericycle Integration and Healthcare Solutions Performance
The company acquired Stericycle and now operates it as the Healthcare Solutions segment. If the company cannot successfully integrate this business, achieve expected cost savings, or maintain customer relationships during the integration, the investment may not deliver the financial benefits originally expected and could significantly harm overall company performance.
Landfill Permits and Capacity Expansion
The company needs permits from government agencies to build, operate, and expand landfills and transfer stations. Getting these permits takes years and faces opposition from local communities. If the company cannot obtain required permits or expand capacity, it may not have enough places to dispose of waste, forcing it to use more expensive alternatives and reducing revenue.
Commodity Price Volatility in Recycling
The company's recycling business depends on selling recyclable materials like cardboard and plastics. Prices for these materials fluctuate dramatically based on market conditions. A $166 million revenue decrease occurred in 2025 due to falling commodity prices, and similar price drops could significantly reduce profits despite the company's heavy investments in recycling facilities.
PFAS and Emerging Environmental Contaminants Regulation
New regulations around PFAS (chemicals in some products and packaging) have already increased the company's landfill operating costs substantially. The company faces potential increases in testing, remediation, and litigation costs as PFAS regulations expand, and these expenses could be much larger than currently anticipated.
Natural Gas Vehicle Fleet Transition Risk
The company invested heavily in a large fleet of natural gas trucks and built fueling stations to support them. Regulatory pressure is shifting toward requiring electric vehicles instead of natural gas vehicles. This transition could make the company's significant investments in natural gas infrastructure and trucks obsolete and require enormous spending on new electric vehicles and charging stations.
