**Hydro One Reports Second Quarter Results**

Hydro One continues to make investments needed to meet future energy needs and support economic and community growth across the province

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

**Second Quarter Highlights** 

&nbsp;&nbsp;&nbsp;&nbsp;• Second quarter basic earnings per share (EPS) of $0.54 compares to EPS of $0.49 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 energy consumption, partially offset by higher depreciation, amortization and asset removal costs and higher financing charges.

&nbsp;&nbsp;&nbsp;&nbsp;• In early June, the Government of Ontario released its first Integrated Energy Plan that outlines its strategy to meet the growth in energy demand to 2050 and proposes new transmission lines to support the growth.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One announced 50 recipients of the Ice Storm 2025: Recovery Grant that will receive up to $10,000 each to support local recovery efforts after the widespread ice storm this past spring.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One and the Power Workers' Union (PWU) announced that PWU members ratified the tentative agreement reached on May 5, 2025 covering employees in front-line and customer-facing roles across the Company's operations.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One released its annual sustainability report highlighting its sustainability performance and continued progress toward its sustainability commitments. The report is available on Hydro One's website <u>(www.hydroone.com/sustainability).</u>

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One is proud to be recognized once again by Corporate Knights on its 2025 list of the Best 50 Corporate Citizens in Canada. This marks the 10<sup>th</sup> consecutive year that Hydro One has made the list.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One was named by Forbes in the first edition of their Canada's Best Employers for Company Culture 2025 list. The Company was also recognized by TIME Magazine and Statista in their first edition of Canada's Best Companies of 2025.

&nbsp;&nbsp;&nbsp;&nbsp;• The Company's capital investments and in-service additions for the quarter were $913 million and $591 million, respectively, compared to $818 million and $526 million in 2024.

&nbsp;&nbsp;&nbsp;&nbsp;• A quarterly dividend of $0.3331 per share was declared, payable on September 29, 2025.

"Ontario is growing fast. In every corner of the province, there's an increasing need for energy to power homes, communities and businesses," said David Lebeter, President and Chief Executive Officer, Hydro One. "Hydro One continues to make critical investments in our transmission and distribution networks to support this need and the expected growth in energy demand that will lead to a more prosperous Ontario."

<sup>1</sup> "Revenues, net of purchased power" is a non-generally accepted accounting principles (GAAP) financial measure. Non-GAAP financial measures do not have a standardized meaning under United States (U.S.) GAAP used to prepare the Company's financial statements and might not be comparable to similar measures presented by other entities. See the section "Non-GAAP Financial Measures".

**Key Financial Highlights** 

<u>2025 Second Quarter Highlights</u>

The Company reported net income attributable to common shareholders of $327 million during the quarter, compared to $292 million in the same period of 2024. This resulted in EPS of $0.54, compared to EPS of $0.49 during the same period in the prior year.

Revenues of $2,066 million for the second quarter were $35 million higher than revenues for the second quarter of 2024. Revenues, net of purchased power<sup>1</sup> of $1,167 million for the second quarter were $76 million higher than revenues, net of purchased power<sup>1</sup> for the second quarter of 2024. The increase is mainly attributable to higher revenues resulting from OEB-approved 2025 rates, as well as higher energy consumption.

Operation, maintenance and administration (OM&A) costs in the second quarter of 2025 were slightly higher than the prior year. Once adjusted for net income neutral items, OM&A was lower than the prior year primarily due to lower work program expenditures, including lower vegetation management expenditures, partially offset by lower insurance proceeds received in the period compared to prior year, and higher asset write-offs.

Depreciation, amortization and asset removal costs for the second quarter of 2025 were higher than the prior year mainly due to higher asset removal costs resulting from storm restoration efforts and growth in capital assets, partially offset by lower amortization of regulatory assets.

Financing charges in the second 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 second quarter of 2025 was higher than the prior year primarily due to higher pre-tax earnings, partially offset by higher deductible timing differences.

<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. See the section "Non-GAAP Financial Measures".

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 $913 million during the second quarter of 2025 and placed $591 million of new assets in-service.

**Selected Operating Highlights** 

Hydro One announced 50 recipients of the Ice Storm 2025: Recovery Grant to support recovery efforts. Through the grant, 12 First Nations and 38 municipalities were selected to receive up to $10,000 in support of local recovery efforts following the widespread ice storm damage across parts of Ontario in the spring.

Hydro One and the PWU announced that PWU members ratified the tentative agreement reached on May 5, 2025. The new agreement is effective from October 1, 2025 to March 31, 2028, and combines the main and Customer Service Organization agreements into one, covering front-line and customer-facing roles. The Company and the Society of United Professionals have commenced with bargaining to renew the collective agreement covering employees in engineering, supervisory and administrative roles.

Hydro One released its annual sustainability report for 2024, outlining the Company's recent achievements including progress on its environmental, social and governance (ESG) commitments. This marks the 10th year that Hydro One has produced a sustainability report, as part of its commitment to producing an annual sustainability update to increase the transparency and accountability of its ESG disclosures. The sustainability report is available at <u>www.hydroone.com/sustainability.</u>

**Common Share Dividends**

Following the conclusion of the second quarter, on August 12, 2025, the Company declared a quarterly cash dividend to common shareholders of $0.3331 per share to be paid on September 29, 2025 to shareholders of record on September 10, 2025.

**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.
