Recent Updates on CLH stock

Clean Harbors saw multiple analyst price target increases over the last day, driven by confidence in its Environmental Services growth, expected acceleration in free cash flow, and a shift from prior recycling headwinds to recycled commodity tailwinds. Additional support came from higher oil prices aiding Safety-Kleen earnings, solid trends despite industrial and base oil uncertainty, and anticipated benefits from new PFAS regulations and ongoing capital allocation. While specific price moves were not detailed, the cluster of upward revisions suggests a constructive market reaction to these improving fundamentals and regulatory catalysts.

Spark’s Take on CLH Stock

According to Spark, TipRanks’ AI Analyst, CLH is a Outperform.

The score is driven primarily by solid financial fundamentals (scale, stable gross margins, and a notably improved balance sheet as reported) and supportive technical momentum (above key moving averages, positive MACD). These positives are tempered by premium valuation (P/E ~38) and some recent cash-flow conversion/FCF volatility, while the earnings call adds a modest positive due to steady 2026 growth guidance and strong capital returns despite near-term segment and macro headwinds.
