On October 1, 2026, Casella Waste Systems, Inc. (the "Company") announced to customers, regulators and the host community of the North Country Environmental Services landfill located in Bethlehem, New Hampshire (the "NCES Landfill") that December 31, 2026 will be the final day that the NCES Landfill accepts municipal solid waste for disposal (the "Closure Date"). The Company had previously reported its expectation that the NCES Landfill would stop accepting waste by the end of 2027, but the Company subsequently modified such timing after an evaluation of the remaining permitted airspace, current and projected fill rates, and other operational factors. The modified timing of the Closure Date will result in a higher level of landfill amortization expense in the fourth quarter of 2026 than previously anticipated, but such expense is not anticipated to have a material impact on the Company’s financial results for the fourth quarter of 2026 and the fiscal year ending December 31, 2026.
