**Hydro One reports first quarter results**

The Company appointed Megan Telford as its President and Chief Executive Officer (CEO) to continue to solidify Hydro One's position as a leading utility

TORONTO, May 13, 2026 - Hydro One Limited (Hydro One or the Company) today announced its financial and operating results for the first quarter ended March 31, 2026.

**First Quarter Highlights** 

&nbsp;&nbsp;&nbsp;&nbsp;• First quarter basic earnings per share (EPS) of $0.65 compares to EPS of $0.60 for the same period in 2025.

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

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One announced that David Lebeter will retire from his role as President and CEO, effective June 9, 2026, and will remain as a Special Advisor with the company until October 10, 2026. The Board announced the appointment of Megan Telford, Chief Operating Officer, as President and CEO effective June 9, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One was selected to develop and construct the Greenstone Transmission Line as well as the Sudbury to Barrie Transmission Line.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One announced the ratification of the tentative agreement with the Society of United Professionals covering employees in engineering, supervisory and other professional roles.

&nbsp;&nbsp;&nbsp;&nbsp;• Subsequent to quarter end, Hydro One received a decision from the OEB regarding its Z-factor application, denying the recovery of $69 million of incremental revenue requirement related to the costs incurred in the significant ice storm in March 2025.

&nbsp;&nbsp;&nbsp;&nbsp;• Subsequent to quarter end, Hydro One was selected to develop and construct the Red Lake Transmission Line.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One announced the appointment of Debbie (Deb) Hutton as the Government of Ontario's nominee to the company's Board of Directors.

&nbsp;&nbsp;&nbsp;&nbsp;• The Company released its annual sustainability report highlighting its 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 and the five First Nation partners on the Chatham by Lakeshore transmission line received the Sustainability Excellence Award by the Electricity Distributors Association for the sustainable partnership behind the construction of the line.

&nbsp;&nbsp;&nbsp;&nbsp;• The Company was recognized by Electricity Human Resources Canada with its Excellence in Workplace Culture Award for its Step Up program, aimed at creating safe spaces for conversations about inclusion, allyship and psychological safety.

&nbsp;&nbsp;&nbsp;&nbsp;• Hydro One was also included in the Globe and Mail's annual Women Lead Here benchmark list.

&nbsp;&nbsp;&nbsp;&nbsp;• The Company's capital investments and in-service additions for the quarter were $715 million and $484 million, respectively, compared to $735 million and $423 million in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;• A quarterly dividend of $0.3531 per share was declared, payable on June 30, 2026.

"This CEO transition marks a continuation of the strong leadership and shared purpose we have built at Hydro One," said David Lebeter, President and Chief Executive Officer of Hydro One. "It has been a privilege to serve alongside such dedicated employees, partners and stakeholders. I am confident that under Megan's leadership, the organization will continue to drive growth and economic prosperity across the province. I thank our Board, employees, partners and shareholders for their trust and support as Hydro One continues to create long-term value."

<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>2026 First Quarter Highlights</u>

The Company reported net income attributable to common shareholders of $391 million during the quarter, compared to $358 million in the same period of 2025. This resulted in EPS of $0.65, compared to EPS of $0.60 during the same period in the prior year.

Revenues of $2,648 million for the first quarter were $240 million higher than revenues for the first quarter of 2025. Revenues, net of purchased power<sup>1</sup> of $1,224 million for the first quarter were $36 million higher than revenues, net of purchased power<sup>1</sup> for the first quarter of 2025. The increase is mainly attributable to higher revenues resulting from OEB-approved 2026 rates, as well as higher average monthly peak demand.

OM&A costs in the first quarter of 2026 were slightly lower than the prior year, mainly attributable to lower work program expenditures, including vegetation management.

Depreciation, amortization and asset removal costs for the first quarter of 2026 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 first quarter of 2026 were higher than the prior year primarily due to an increase in outstanding long-term debt, partially offset by higher capitalized interest.

Income tax expense for the first quarter of 2026 was lower than the prior year primarily due to higher deductible timing differences, partially offset by higher pre-tax earnings. Income tax expense for the period was higher than the prior year when adjusted for additional tax deductions from the re-introduction of accelerated capital cost allowance, that are offset by a corresponding reduction in revenue, and therefore net income neutral.

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 $715 million during the first quarter of 2026 and placed $484 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.

The Company was selected to develop and construct a new priority transmission line between Sudbury and the Barrie area.

**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; distribution revenues, net of purchased power, is defined as distribution revenues less the cost of purchased power. These measures are used internally by management to assess the impacts of revenue on net income and are 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.
