Insiders are buying Republic Services, Inc. (RSG), and not by a small margin. Over the 180 day window ending September 11th, 2026, open market purchases totaled $1.58 billion against $458,181 in sales, for net buying of $1,582,230,513. The direction here is not ambiguous.
The ledger breaks down this way: 107 buy filings from 2 distinct buyers, and 3 sell filings from 2 distinct sellers. One side of that tally is a sustained, repeated accumulation program. The other is a handful of modest dispositions that would not register at all without the contrast.
Cascade Investment, L.L.C. was the largest buyer, filing in the role of Other, with $1,482,160,087 in open market purchases. The firm is an entity rather than an officer or director, and its filings sit alongside the rest of the buy activity that lifted the period total to $1.58 billion. Entity buyers of this size file for a different reason than a vice president topping up a personal stake, and the scale of the position is what makes the number land.
On the sell side, the largest seller was Sandra M Volpe, a Director, at $380,304. That single figure accounts for most of the $458,181 sold across the entire window by both sellers combined. Set against the buy column, director level selling at this scale is closer to housekeeping than to a signal.
Republic Services last traded at $236.28, with a market capitalization of $72,352,006,144. The company operates in the Refuse Systems sector, a business built on collection routes, transfer stations, landfills and recycling facilities, which is about as far from a speculative growth story as the market offers. Readers tracking price action over the same window should pull the chart themselves rather than read a trend into the filing data.
What the ledger does not say matters as much as what it does. Only Form 4 codes P and S are counted here, meaning awards, tax withholding and option exercises are excluded entirely. Those events move shares into and out of insider accounts without anyone making a decision to buy or to sell, and counting them would badly distort both columns.
A sale also does not always mean what readers assume. Insiders routinely sell under 10b5-1 plans adopted months in advance, which schedule dispositions on fixed dates regardless of what the seller thinks about the stock on the day it executes. Diversification, tax bills and estate planning all produce sales that carry no view on the business. The same caution runs the other direction: a purchase filing records what was bought and when, not the reasoning behind it, and nothing in the filings explains why any buyer acted.
What a reader can take from this window is the shape of it. Two buyers, 107 purchase filings, $1.58 billion deployed on the open market, and $458,181 going the other way from two sellers. That is a heavily one sided record, concentrated in a single large entity buyer rather than spread across the officer and director ranks.
