Insiders are buying REPUBLIC SERVICES, INC. (RSG). Over the trailing 180 day window, open market Form 4 activity at the refuse systems company points one direction: net buying, and by a margin wide enough that the sell side barely registers. The most recent transaction covered here is dated September 11th, 2026.
The ledger is lopsided. There were 107 buy filings and 3 sell filings, spread across 2 distinct buyers and 2 distinct sellers. Purchases totaled $1.58 billion. Sales totaled $458,181. That leaves net buying of $1,582,230,513 for the window.
The scale here comes from a single institution rather than a crowd of executives. Cascade Investment, L.L.C., filing in the role of Other, accounts for $1,482,160,087 of the buying, the largest buyer in the window by a wide distance. Because the buyer is an entity, the filings reflect a decision made at the firm level rather than by an individual officer.
On the other side, the largest seller was Volpe Sandra M, a Director, at $380,304. That is the bulk of the $458,181 sold across all three sell filings. For scale, the entire sell side of this window is smaller than many single grants at a company of this size.
Republic Services last traded at $229.65, against a market capitalization of $70,321,815,552. Readers should match the dollar figures above to that price level rather than to any assumed entry point: Form 4 data records what was transacted and when, not what the buyer paid relative to any particular benchmark.
What the ledger does not say matters as much as what it does. Only Form 4 codes P and S are counted here, which means awards, tax withholding and option exercises are excluded. Those events move share counts around but they are not decisions to buy or to sell in the open market, and including them would distort the picture in both directions.
A sale also carries less information than a purchase. Directors and officers routinely sell under scheduled 10b5-1 plans adopted months in advance, and such a sale can execute on a date the seller never chose. Nothing in the filings explains motive on either side of this ledger. A large purchase by an institution may reflect portfolio construction, rebalancing or an existing relationship with the issuer, and the filing itself says none of that.
The concentration point is worth repeating. With 2 distinct buyers producing 107 filings, the buying is not broad participation across the officer and director group. It is dominated by Cascade Investment, L.L.C., and any reading of the signal should account for that single source rather than treating it as a consensus view from inside the company.
