Jana Partners discloses stake in Casella Waste Systems and urges 27% EBITDA margin by 2029

Activist firm Jana Partners revealed a new position in Casella Waste Systems and called for operational improvements. Jana’s managing partner Scott Ostfeld said the company should raise its EBITDA margin to 27% by 2029 and align executive compensation with shareholder value. The firm also suggested hiring a performance‑improvement consultant. Casella reported a 22.7% EBITDA margin for the quarter ended June 30, 2026.

The activist push could pressure Casella to cut costs and improve margins, potentially boosting future earnings and valuation. Jana’s public target may also increase stock volatility as investors assess the feasibility of the 27% margin goal.
