WASTE MANAGEMENT INC (WM) stock intrinsic value fair value estimate & owner earnings analysis

Waste Management is North America's largest garbage company. It collects trash and recycling from homes, businesses and towns across the United States and Canada, and owns or operates 257 landfills, the largest such network on the continent, plus 342 transfer stations that funnel waste to them. Landfills are the core of the moat: new ones are very hard to permit, so owning the disposal site lets the company keep its own trucks' waste and charge competitors to dump. Since November 2024 it also owns Stericycle, now called Healthcare Solutions, which handles medical waste and shredding in the United States, Canada and Western Europe. A smaller Renewable Energy business turns landfill gas into renewable natural gas and electricity, and a Recycling business sorts and sells cardboard, paper, plastic and metal. How we measure earnings. We start from operating cash flow, take out stock compensation, strip out short-term swings in receivables and payables, and deduct the capital spending needed to keep the business running, treating only spending tied to revenue growth as optional. We leave in the cash spent capping, closing and cleaning up old landfills, because that is a real, permanent cost of this business. On that basis owner earnings per share rose from about $3.47 in 2016 to $5.52 in 2024 and $8.76 in 2025. Because the company carries a lot of debt, we value the business before its lenders by adding back cash interest ($927 million in 2025, up from $530 million as Stericycle debt came on), then subtract the debt. That gives a business cash flow of about $4.47 billion for 2025. Large amounts of the acquired companies' customer relationships are written off each year ($421 million in 2025); we let that charge come back into cash flow, but we do not credit any growth from Healthcare Solutions beyond what has been shown, and our weakest case lets some of it fade. The starting level. 2025 is the only full year of the business as it now exists, so we cannot take a median of many comparable years. We start from about $4.1 billion rather than $4.47 billion for two concrete reasons: cash taxes fell to $494 million from $645 million because of new bonus depreciation rules, which is a timing benefit rather than a permanent one, and some of the $519 million of cash tied up in receivables in 2025 is the larger healthcare business needing more working capital, not just timing. The first half of 2026 supports the level: operating cash flow was $3.23 billion against $2.75 billion a year earlier, and capital spending fell. Owner earnings grew about 59% in 2025, almost all from the acquisition; we assume only 4% for the first year. Base case, about $215 per share. Prices rise a few percent a year as they have for decades, small tuck-in acquisitions continue at their long-run pace, and the renewable gas plants already built keep producing. Business cash flow grows 4% a year for five years, 3.5% for the next five, then 2% thereafter, supported by landfill airspace that lasts decades and contracts that escalate with inflation. The business is worth about $107.5 billion; it owes about $22.8 billion net of cash, reduced by roughly $2 billion because most of its bonds are fixed at an average of 4.3% and run as late as 2054, leaving about $86.7 billion for shareholders. Bear case, about $132 per share. We include a recession like 2008-2009, when the company's revenue fell roughly 12% as construction and industrial waste volumes dropped. Business cash flow falls from about $4.1 billion to roughly $3.5 billion over two years, recovers over three, and Healthcare Solutions loses about $180 million a year of cash flow over a decade if the promised cost savings, which the company itself warns may not arrive, do not materialize. Growth after recovery is only 1%. Even at the trough, cash flow covers interest more than three times. Refinancing in this case is assumed to cost more, so the low-coupon benefit is cut to $1 billion. The business is worth about $75 billion, owes about $21.8 billion, leaving about $53 billion. Bull case, about $285 per share. The same pricing record runs at 5.5% a year for a decade, helped by the renewable gas plants and automated recycling facilities that are already built and paid for, and Healthcare Solutions delivers about $250 million of yearly cost savings by its third year. Growth then settles at 2.5%. The business is worth about $135.6 billion, owes about $20.8 billion after the bond benefit, leaving about $114.8 billion. Debt. Total borrowings were about $23.4 billion at June 30, 2026, with roughly $557 million of cash. Scheduled repayments run about $1.8 to $2.1 billion a year through 2030. The company has refinanced comfortably for decades and cash flow covers interest more than four times today, so we see no maturity that threatens shareholders, but the debt load means a modest disappointment in earnings moves the share value more than it would for an unlevered company. Landfill closure and cleanup obligations are not subtracted separately because their cash cost is already inside our earnings figure. The margin-of-safety price. We are fairly confident in the earnings level: trash collection is essential, customers rarely leave, and the company's cash flow fell only modestly in 2009 and 2020. What we are least sure of is how much of 2025 was helped by one-off tax and working-capital timing, and whether Healthcare Solutions, a business that struggled before the acquisition, earns its keep. The worst realistic outcome is a deep recession hitting at the same time Healthcare Solutions disappoints. The structure would survive it: there is no customer concentration, the landfills are hard assets nobody can replicate, and the debt is long-dated and mostly fixed. If we are wrong on the level and business cash flow simply stays near $3.6 billion forever with no growth at all, the shares would be worth about $95. The price assumes a holding period of about five years, during which the company pays a dividend of $3.30 a share that has risen every year. At $100 a share, the shares are roughly covered even by that no-growth outcome, while the base case would be worth about $245 five years out, which together with dividends implies about 20% a year. Above that price, the estimate would rely on the base case to reach the target with little protection if the healthcare business or the 2025 cash flow proves weaker than it looks. Our previous figures were prepared on a different basis and are not comparable.
