Second Quarter Results Reported by Hydro One

Hydro One Reports Second Quarter Results

TORONTO – Hydro One Limited (Hydro One or the Company) today announced its financial and operating results for the second quarter ended June 30, 2023.

Second Quarter Highlights

• Second quarter basic earnings per share (EPS) of $0.44 was 2.3% higher compared to EPS of $0.43 for the same period in 2022.
• EPS for the quarter was higher year-over-year largely due to higher revenues resulting from Ontario Energy Board (OEB)-approved 2023 transmission rates and lower asset removal costs resulting from fewer storm-related asset replacements, partially offset by higher operation, maintenance and administrative (OM&A) costs and higher financing charges.
• Subsequent to the quarter end, the Company announced that it filed an application with the OEB to seek approval to construct both phases of the Waasigan Transmission Line Project. The total project is expected to cost approximately $1,200 million and be in service close to the end of 2025 and 2027 for Phase 1 and Phase 2, respectively.
• The Company broke ground on its Chatham to Lakeshore Transmission Line which will provide clean electricity to support growth in the agri-food and manufacturing industries. The Company also announced the preferred route for the St. Clair Transmission Line that maximizes existing infrastructure while improving reliability.
• Hydro One and the Power Workers’ Union (PWU) reached a tentative settlement for two collective agreements covering employees in front-line and customer facing roles across the Company’s operations.
• Subsequent to the quarter, Hydro One released its annual sustainability report (www.hydroone.com/sustainability) that demonstrates continued progress in setting and meeting its sustainability goals.
• Hydro One and the Coaches Association of Ontario announced Hydro One has provided grants to 38 Indigenous coaches to boost representation in sports leadership.
• Hydro One received its 14^th Emergency Response Award from the Edison Electric Institute (EEI) for restoration efforts after Winter Storm Elliot.
• Hydro One was recognized as one of the Best 50 Corporate Citizens in Canada by Corporate Knights.
• Hydro One announced that Brian Vaasjo, Helga Reidel and Mitch Panciuk have been appointed to the Company’s Board of Directors.
• The Company’s capital investments and in-service additions for the quarter were $649 million and $413 million, respectively, compared to $612 million and $547 million in 2022.
• Quarterly dividend declared at $0.2964 per share, payable September 29, 2023.

Key Financial Highlights

2023 Second Quarter Highlights

The Company reported net income attributable to common shareholders of $265 million during the quarter, compared to $255 million in the same period of 2022. This resulted in EPS of $0.44, compared to EPS of $0.43 in the prior year.

Revenues, net of purchased power[1] of $1,059 million for the second quarter were $71 million higher than revenues, net of purchased power¹ for the second quarter of 2022. The increase is mainly due to revenues resulting from OEB-approved 2023 transmission rates as well as higher revenues related to the OEB-approved recovery of historical cost deferrals recognized as regulatory assets in prior periods. The impacts of the recovery of regulatory assets are offset by a net increase in OM&A and income tax expense and are net income neutral in the period.

OM&A costs in the second quarter of 2023 were higher than the prior year as a result of higher corporate support costs, primarily attributable to lower capitalized overheads associated with the timing and volume of capital activity, the aforementioned recovery of historical cost deferrals which are offset in revenues and higher work program expenditures, including emergency restoration, information technology initiatives and stations maintenance.

Non-GAAP financial measures do not have a standardized meaning under US 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”.

Financing charges in the second quarter of 2023 were higher than the prior year resulting from higher weighted-average interest rates on long-term debt and short-term notes.

Depreciation, amortization and asset removal costs for the second quarter of 2023 were lower than the same period of the prior year primarily due to lower asset removal costs resulting from fewer storm-related asset replacements which was partially offset by higher depreciation and amortization expense related to the growth in capital assets as the Company continues to place new assets in-service, consistent with its ongoing capital investment program.

Income tax expense for the second quarter of 2023 was slightly lower than the prior year primarily due to higher deductible timing differences compared to the prior year.

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 $649 million during the second quarter of 2023 and placed $413 million of new assets in-service.

Selected Operating Highlights

The Company announced that it filed with the OEB a leave to construct application under Section 92 of the Ontario Energy Board Act, 1998, for its Waasigan Transmission Line Project. The project is expected to cost $1,200 million. The first phase is a proposed new double-circuit 230 kilovolt transmission line from Lakehead Transformer Station (TS) in the Municipality of Shuniah to Mackenzie TS in the Town of Atikokan to be in service as close to the end of 2025 as possible. Phase two is a proposed new single-circuit 230 kilovolt transmission line from Mackenzie TS to Dryden TS in the City of Dryden, which is expected to be in service by the end of 2027. The project is being built in partnership with nine First Nation communities.

The Company broke ground on its Chatham to Lakeshore Transmission Line. This $268 million investment will drive the province of Ontario’s clean energy value chain and help make Southwestern Ontario the hub for agri-food and manufacturing. The Company has offered five First Nations in the region a 50% equity stake in the transmission line component of the project. The line is expected to be in service by the end of 2025.

The Company announced Route 2 as the preferred route for the proposed St. Clair Transmission Line after a thorough evaluation of five options. This option was selected as 80% of the route uses existing transmission corridors and upgrades an existing transmission line. The Company will offer proximate First Nations impacted by the project a 50% equity stake in the transmission line component of the project. The line is expected to be in service in 2028.

Hydro One reached tentative settlements for two collective agreements with the PWU which includes front-line staff and customer facing roles. Once ratified, these agreements will be in effect until September 30, 2025.

Hydro One released its sustainability report which provides a balanced account of its environmental, social and governance (ESG) performance against the sustainability targets released last year. Hydro One is committed to producing an annual sustainability update to continuously increase the transparency and accountability of our ESG disclosures.

The Emergency Response Awards are presented to EEI member companies for recovery and assistance efforts of electric companies following service disruptions caused by extreme weather or other natural events.

Hydro One announced that Brian Vaasjo, Helga Reidel and Mitch Panciuk were appointed to the Company’s Board of Directors effective June 2, 2023.

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. Non-GAAP financial measures do not have a standardized meaning under GAAP used to prepare the Company’s financial statements and might not be comparable to similar measures 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 US GAAP.

Revenues, Net of Purchased Power

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.
