MCKIM ALAN S
MCKIM ALAN S is a corporate insider (EXEC CHAIR, CTO.) at CLEAN HARBORS INC (CLH) filing SEC Form 4 transactions. 172 transactions, totaling $1,165,000 in purchases and $213,205,379 in sales. Source: SEC EDGAR.
There is no cross-company pattern in Alan McKim's Form 4 history: all 172 recorded transactions relate to Clean Harbors. Within that single-company record, the direction is unmistakably distributive—3.15 million shares sold versus 25,000 bought over the full history. The latest discretionary sale was 100,000 CLH shares at $292.65 on March 4, 2026.
The two newer entries are different in kind: 1,343 shares on July 1 and 1,265 shares on July 17 were coded as tax-withholding or compensation-related dispositions, not open-market sales. They extend a recurring administrative pattern seen in prior years and should not be treated as evidence of market timing. McKim's record is best read as persistent long-term selling punctuated by gifts and routine withholding events, not as a multi-issuer trading signal.
