As the Q1 earnings season comes to a close, it’s time to take stock of this quarter’s best and worst performers in the waste management industry, including Clean Harbors (NYSE: CLH) and its peers.

Waste management companies can possess licenses permitting them to handle hazardous materials. Furthermore, many services are performed through contracts and statutorily mandated, non-discretionary, or recurring, leading to more predictable revenue streams. However, regulation can be a headwind, rendering existing services obsolete or forcing companies to invest precious capital to comply with new, more environmentally-friendly rules. Lastly, waste management companies are at the whim of economic cycles. Interest rates, for example, can greatly impact industrial production or commercial projects that create waste and byproducts.

The 9 waste management stocks we track reported a mixed Q1. As a group, revenues missed analysts’ consensus estimates by 2.3%.

While some waste management stocks have fared somewhat better than others, they have collectively declined. On average, share prices are down 4.8% since the latest earnings results.

Market Update

Late in 2025 into early 2026, there was hand wringing around artificial intelligence. For software companies, the fear was that AI would erode pricing power and compress margins as new tools made it easier to replicate what once required expensive enterprise platforms. Crypto investors had their own version of the same anxiety: if AI agents could trade, allocate capital, and manage wallets autonomously, what exactly was the long-term value of today’s crypto infrastructure?

These concerns triggered a noticeable rotation away from these sectors and into safer havens. But markets rarely dwell on one narrative for long. Spring 2026 came, and the focus shifted abruptly from technological disruption to geopolitical risk. The US’ conflict with Iran became the dominant driver of market psychology, and when geopolitics takes center stage, the script changes quickly. Investors stop debating growth rates and start worrying about oil supply, inflation, and global stability.
