## Exhibit 99.1

**Exhibit 99.1** 

**Hydro One highlights safety performance, Indigenous procurement and partnerships in its 2025 Sustainability Report** 

*The company exceeds Indigenous spending target ahead of schedule* 

TORONTO, May 7, 2026 – Today, Hydro One Limited (Hydro One) announced the release of its 2025 Sustainability Report, titled *Connecting power and possibility.* The report details a strong safety performance, progress towards increasing Indigenous and domestic procurement and the build out of Ontario's transmission system in partnership with First Nation governments.

The company achieved a recordable injury rate of 0.68 per 200,000 hours worked, well below industry standards. This result reflects operational discipline, continuous improvement and dedication to ensuring every employee goes home safe at the end of each day.

Leadership in Indigenous partnership and economic reconciliation remains a priority. In 2025, Hydro One spent approximately $216 million – or more than 7 per cent of its total sourceable spend – on purchases with Indigenous businesses, exceeding its target of 5 per cent by 2026. This complements the company's strong position to deliver key projects through its industry-leading First Nation Equity Partnership Model. By the end of 2025, Hydro One had been designated 12 transmission lines.

Hydro One also took major steps forward to reinforce supply chain resilience amid global uncertainty. Through its Ontario and Canada first procurement strategy, the company directed more than 90 per cent of its total procurement spending to Canadian suppliers. This included an investment to expand Ontario-based transformer manufacturing to increase local production capacity.

"Ontario's long-term demand for electricity is increasing. Hydro One will continue to focus on sustainable solutions to meet the needs of the people of Ontario, and support the province's broader economic goals," said Lisa Pearson, Executive Vice President, Corporate Affairs, Hydro One. "Our focus on safety, Canadian procurement and strategic investments and Indigenous partnerships is supporting our efforts to build a strong, reliable and secure system. Hydro One's success is tied to Ontario's success, and we will continue to do our part to deliver value for customers, partners and communities."
