DBRS Morningstar Confirms Ratings of Hydro One Inc. at A (high)/R-1 (low), Stable Trends

DBRS Limited (DBRS Morningstar) confirmed the Issuer Rating and Senior Unsecured Debentures rating of Hydro One Inc. (HOI or the Company) at A (high), and the Commercial Paper rating at R-1 (low). All trends are Stable. The confirmations reflect the regulated nature of HOI's transmission and distribution businesses, which provide a steady stream of earnings and cash flows. The Stable trends are based on the Company's key credit metrics, which are all in line with the "A" rating category.

In October 2022, HOI filed a settlement proposal with the Ontario Energy Board for its Joint Rate Application (JRAP) for 2023 to 2027 transmission revenue requirements and distribution rates. The settlement proposal, which is largely based on a continuation of the current Custom Incentive Rate-making (IR) framework, will be updated in mid-November to reflect the Ontario Energy Board’s (OEB) 2023 cost of capital parameters and inflation factor. DBRS Morningstar notes, if approved, the settlement proposal will provide stability for HOI's operations during the IR term, and certainty of funding for the significant capital expenditures (capex) program of around $11.8 billion. The OEB is reviewing the settlement proposal and a decision on the JRAP is expected by the end of 2022.

HOI's financial risk assessment continues to be reasonable for the A (high) ratings. The Company's key credit metrics have been stable over the past few years and in line with the "A" rating category. If the JRAP settlement proposal is approved, HOI's key credit metrics should remain supportive of the current ratings, albeit with some pressure on the cash flow-to-debt ratio because of the planned capex program. DBRS Morningstar expects the Company to continue to manage its capex and dividend requirements through a prudent mix of debt issuances and operating cash flows in order to maintain leverage in line with the regulatory capital structure and other key ratios within the "A" rating category. A negative rating action may occur if HOI's key credit metrics weaken to a level no longer commensurate with the current rating category for a sustained period, such as if the cash flow-to-debt ratio falls below 12.5% and the debt-to-capital ratio increases above 60%. A positive rating action is considered unlikely over the medium term given the Company's current business and financial risk profiles and the substantial capex program.
