**Hydro One Reports Third Quarter Results**

Hydro One is supporting economic and community growth in southwestern Ontario through construction of the St. Clair Transmission Line Project

TORONTO, November 13, 2025 - Hydro One Limited (Hydro One or the Company) today announced its financial and operating results for the third quarter ended September 30, 2025.

**Third Quarter Highlights** 

&nbsp;&nbsp;&nbsp;&nbsp;• Third quarter basic earnings per share (EPS) of $0.70 compares to EPS of $0.62 for the same period in 2024.

&nbsp;&nbsp;&nbsp;&nbsp;• The change in EPS year-over-year was largely due to higher revenues resulting from Ontario Energy Board (OEB)-approved 2025 transmission and distribution rates and higher average monthly peak demand, partially offset by higher financing charges, and higher depreciation.

&nbsp;&nbsp;&nbsp;&nbsp;• David Lebeter resumed his role as President and Chief Executive Officer as of November 12, 2025. Mr. Lebeter was on a compassionate care leave since August 25, 2025 to care for a family member.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One, alongside First Nation partners and provincial and municipal leaders, celebrated the groundbreaking of the St. Clair Transmission Line Project in southwestern Ontario.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One employees donated generously during our annual Power to Give Month campaign, raising more than $2.1 million for Canadian causes that were selected by them. These funds are made up of employee donations that were matched by Hydro One. Employees also tracked more than 5,200 volunteer hours that were dedicated to local causes in their communities.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One's Energizing Life Funds recognized 28 Indigenous communities, charitable organizations and municipalities that received $25,000 each to support local initiatives.

&nbsp;&nbsp;&nbsp;&nbsp;• For the second year in a row, Hydro One was recognized with the Ontario Energy Association's Company of the Year Award.

&nbsp;&nbsp;&nbsp;&nbsp;• The Company priced an offering of $1.1 billion aggregate principal amount of Medium-Term Notes under its Sustainable Financing Framework.

&nbsp;&nbsp;&nbsp;&nbsp;• The Company's capital investments and in-service additions for the quarter were $779 million and $577 million, respectively, compared to $773 million and $597 million in 2024.

&nbsp;&nbsp;&nbsp;&nbsp;• A quarterly dividend of $0.3331 per share was declared, payable on December 31, 2025.

"Electricity demand in southwestern Ontario is growing fast, and Hydro One continues to support this growth through development of critical infrastructure, such as the St. Clair Transmission Line Project, to strengthen power resiliency and reliability in the region," said David Lebeter, President and Chief Executive Officer, Hydro One. "Hydro One's success is tied to Ontario's success and we continue to support homegrown businesses. Last year, more than 93% of our procurement was from companies based in Canada—of which 76% was from companies based in Ontario."

**Key Financial Highlights** 

<u>2025 Third Quarter Highlights</u>

The Company reported net income attributable to common shareholders of $421 million during the quarter, compared to $371 million in the same period of 2024. This resulted in EPS of $0.70, compared to EPS of $0.62 during the same period in the prior year.

Revenues of $2,299 million for the third quarter were $107 million higher than revenues for the third quarter of 2024. Revenues, net of purchased power<sup>1</sup> of $1,219 million for the third quarter were $74 million higher than revenues, net of purchased power<sup>1</sup> for the third quarter of 2024. The increase is mainly attributable to higher revenues resulting from OEB-approved 2025 rates, as well as higher average monthly peak demand.

Operation, maintenance and administration (OM&A) costs in the third quarter of 2025 were comparable to the prior year.

Depreciation, amortization and asset removal costs for the third quarter of 2025 were higher than the prior year mainly due to growth in capital assets as the company continues to place new assets in service, partially offset by lower asset removal costs.

Financing charges in the third quarter of 2025 were higher than the prior year primarily as a result of an increase in long-term debt outstanding, partially offset by higher capitalized interest.

Income tax expense for the third quarter of 2025 was higher than the prior year primarily due to higher pre-tax earnings, partially offset by higher deductible timing differences.

Hydro One continues to invest in the reliability and performance of Ontario's electricity transmission and distribution systems by addressing aging power system infrastructure, facilitating connectivity to new load customers and generation sources, and improving service to customers. The Company made capital investments of $779 million during the third quarter of 2025 and placed $577 million of new assets in-service.

<sup>1</sup> Revenues, net of purchased power, is a non-GAAP financial measure. Non-GAAP financial measures do not have a standardized meaning under U.S. GAAP used to prepare the Company's financial statements and might not be comparable to similar measures presented by other entities.

**For More Information**

For more information about everything Hydro One, please visit <u>www.hydroone.com</u> where you can find additional information including links to securities filings, historical financial reports, and information about the Company's governance practices, corporate social responsibility, customer solutions, and further information about its business.

**Non-GAAP Financial Measures**

Hydro One uses a number of financial measures to assess its performance. The Company presents revenues, net of purchased power to reflect revenues net of the cost of purchased power, which is a non-GAAP financial measure. Since these specified financial measures and financial ratios may not have a standardized meaning within U.S. GAAP, results may not be comparable to similar financial measures and financial ratios presented by other entities. They should not be considered in isolation nor as a substitute for analysis of the Company's financial information reported under U.S. GAAP.

<u>Revenues, Net of Purchased Power</u>

Revenues, net of purchased power is defined as revenues less the cost of purchased power. Revenues, net of purchased power is used internally by management to assess the impacts of revenue on net income and is considered useful because it excludes the cost of power that is fully recovered through revenues and therefore net income neutral.

The following table provides a reconciliation of GAAP (reported) revenues to non-GAAP (adjusted) revenues, net of purchased power on a consolidated basis.
