Insiders are buying REPUBLIC SERVICES, INC. (RSG), and the imbalance is not close. Over the trailing 180 days the open market Form 4 record shows net buying of $1,582,230,513, driven almost entirely by a single institutional holder.
The ledger breaks down this way. There were 107 buy filings from 2 distinct buyers, totaling $1.58 billion. Against that sit 3 sell filings from 2 distinct sellers, totaling $458,181. The most recent transaction covered here is dated September 11th, 2026.
The largest buyer was CASCADE INVESTMENT, L.L.C., filing in the role of Other, with $1,482,160,087 of purchases. That single entity accounts for most of the buy side total on its own, and the high filing count is consistent with a position built in many separate open market lots rather than one block.
The largest seller was Volpe Sandra M, a Director, at $380,304. That is the biggest single disposal on the record, and it still amounts to a rounding error next to the buy column. Two sellers in six months is a thin sell side for a company of this size.
Republic Services operates in the Refuse Systems business and carries a market capitalization of $66,197,123,072. Shares last traded at $216.18. The Form 4 record itself does not carry a price history, so readers who want to see how the stock moved alongside these purchases should pull a chart covering the same 180 day window rather than infer direction from the filings.
It is worth being precise about what this ledger does not say. 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 sell, and including them would blur the signal. Everything above reflects transactions an insider or holder chose to execute in the open market.
The sell side carries its own caveat. A sale can be a scheduled 10b5-1 plan set up months in advance, which removes discretion from the timing entirely. Diversification, tax bills and estate planning all produce sales that say nothing about a seller's view of the business. The same discipline applies in reverse: the filings show that Cascade Investment, L.L.C. bought, and they do not state a reason, so no reason should be read into them here.
What the record does establish is scale and persistence. A buy count of 107 filings spread across the window, concentrated in one institutional holder filing as Other, is a different pattern from a single opportunistic purchase. The three sales on the other side came from Director level filers and were small in dollar terms.
