(Timing: Immediate to medium-term, as earnings were just announced and guidance is for the full year 2026. The acquisition is expected to close in the second half of 2026.)

The definitive acquisition of Terra Nova Solutions will unlock value through enhanced service offerings, increased scale in hazardous waste management, and the realization of expected annual synergies. This amount is moderate compared with the company's size. (Timing: Synergies are anticipated after the first full year of operation, with integration ongoing over the medium term.)

Better-than-expected first-quarter 2026 financial results, including highest Q1 revenue in company history, and a significant raise to the full-year 2026 Adjusted EBITDA and Adjusted Free Cash Flow guidance. (Timing: Throughout 2026, as the company executes on its raised guidance.)

The combination of better-than-expected Q4 2025 results, positive 2026 guidance, the expanded share repurchase program, and the DCI acquisition should drive continued investor interest and potentially lead to price appreciation. (Timing: Short-term to medium-term, with the DCI acquisition closing in the first half of 2026 providing a mid-term boost.)
