Bill Gates’ $119 Million Waste Bet: What the Headline Leaves Out

Cascade bought approximately $119 million of Republic Services shares. The 0.47% addition to its existing holding reveals why ownership, earnings, competitors, and valuation matter.

Cascade added to a substantial Republic Services holding. Understanding the purchase requires looking at the position, the business, and the price.

Bill Gates’ investment company has bought another approximately $119 million of Republic Services stock. The recognizable name and large dollar amount make an obvious headline. The more useful story is what sits behind it: an established investment, a business growing through pricing despite weaker volumes, and a purchase that says less about an investor’s motives than it first appears.

Our Amrize case study examined why the size and context of an insider purchase matter. Republic Services takes that question further: what should an investor make of a large purchase in a company that is already a substantial holding?

On September 1 and 2, 2026, Cascade Investment purchased 534,000 Republic Services shares. The transactions were disclosed in a Form 4 filed on September 3. Cascade owns the shares directly; Gates, its sole member, is also reported as a beneficial owner. These are two names associated with the same holding, rather than two independent investors making separate purchases. SEC filing

The purchases increased the reported holding from approximately 114.49 million shares to 115.02 million. That makes the addition about 0.47% of the shares Cascade already held. The dollar amount is substantial, but the transaction represents an incremental addition to an established position. An earlier August disclosure had already documented further purchases and reported a 36.7% stake at that time. That historical percentage should not be confused with a newly calculated September ownership figure. August ownership disclosure

To understand the business behind the purchase, start with an everyday necessity. Republic collects, processes, recycles, and disposes of waste. Its investment appeal must ultimately rest on how successfully it turns those services into earnings and cash, rather than on the identity of a shareholder.

Republic released its second-quarter results on August 6, before these September purchases. Revenue rose 4.6% to $4.43 billion, and adjusted earnings per share increased to $1.85 from $1.77. Yet the growth was uneven: pricing contributed positively while volume reduced revenue growth by 1.6 percentage points. Adjusted EBITDA margin, a measure of profitability before interest, taxes, depreciation, amortization, and specified adjustments, held at 32.1%. Management also raised its full-year outlook. Republic’s quarterly results

In plain English, Republic generated more revenue and higher adjusted earnings while handling weaker volume. That supports a case for pricing strength and operating resilience. It also sets a limit on the story: these results do not describe a surge in underlying demand, and the reported adjusted margin did not expand.

The competitive picture adds another useful check. In the same quarter, Waste Management reported $6.68 billion of revenue, growth of 4.0%, and an adjusted operating EBITDA margin of 30.9%. Waste Connections reported $2.56 billion of revenue, growth of 6.4%, and an adjusted EBITDA margin of 32.8%. Republic therefore sat between those two peers on revenue growth and reported adjusted margin. WM results · Waste Connections results

These company-adjusted measures are useful reference points, rather than a perfectly standardized ranking. Business mix, acquisitions, and adjustments differ. Even so, the comparison challenges an easy assumption: Gates’s involvement does not establish that Republic is the fastest-growing or most profitable business in its peer group.

The chronology matters as well. Republic’s quarterly results were public before Cascade’s September purchases. Readers can examine that information alongside the transactions, but the filing does not establish that the earnings announcement caused the buying. It does not disclose Cascade’s valuation model, investment horizon, or expected return.

That leaves the most consequential question unanswered: was the purchase price attractive? An essential service can be a strong business and still offer a disappointing investment return if bought too expensively. A complete assessment would need to weigh valuation, debt, future cash generation, and competing opportunities. The ownership disclosure alone cannot settle that question.

The lesson is to use a recognizable investor’s purchase as the beginning of research. Here, the evidence shows continued investment in an established holding, supported by a resilient business but accompanied by weaker volumes and capable competitors. As with Amrize, context changes the meaning of the headline. The next research question is whether the price adequately reflects both that resilience and those constraints.
