Superinvestors (SEC 13F-HR, Q2 2026) (CLH)
2 of 80 tracked investors hold CLH. Each row is the investor's latest 13F; change is vs their prior-quarter share count.
| Investor | Firm | % of portfolio | Value | Change |
|---|---|---|---|---|
| Henry Ellenbogen | Durable Capital Partners | 2.59% | $267M | Reduced -15.1% |

Insider sales (SEC Form 4, open-market, last ~7 months) (CLH)
0 of 3 under a Rule 10b5-1 trading plan (scheduled in advance). Unplanned sales were timed by the insider.
| Trade date | Insider | Role | Shares | Value | % of holdings sold | 10b5-1 plan | Insider type |
|---|---|---|---|---|---|---|---|
| 2026-08-14 | Gerstenberg Eric W | CO-CEO | 2,500 | $803K | 4.2% | No | Opportunistic (traded every year 2023–2025, no repeating month) |
| 2026-08-03 | Robertson Andrea | Director | 789 | $248K | 8.1% | No | Opportunistic (traded every year 2023–2025, no repeating month) |
| 2026-05-26 | States Lauren | Director | 789 | $226K | 6.5% | No | Routine (sold in May each year 2023–2025) |
% of holdings sold = shares sold ÷ (shares sold + all holdings the insider reported on that Form 4, direct and through trusts).
Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.
