On June 10, 2026, the Company’s regulated water and wastewater operating subsidiaries in Ohio received an order from the Public Utilities Commission of Ohio (“PUCO”) approving new base rates designed to increase operating revenues on an annual basis by $10,536.

During the first six months of 2026, two of the Company’s water utility operating divisions in Ohio and two of the Company’s wastewater utility operating divisions in Indiana implemented approved base rate increases designed to increase total operating revenues on an annual basis by $1,834 and by $1,003, respectively.
