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

DBRS Limited (DBRS Morningstar) confirmed Hydro One Inc.'s (HOI or the Company) Issuer Rating and Senior Unsecured Debentures rating at A (high), and the Commercial Paper rating at R-1 (low). All trends are Stable. The credit ratings of HOI are based on its regulated electricity distribution and transmission operations in the Province of Ontario (the Province; 47.1%; rated AA (low) with a Positive trend by DBRS Morningstar), which operates under a reasonable regulatory framework by the Ontario Energy Board (OEB). The Stable trends reflect the Company's financial risk assessment, with all key credit metrics in line with the "A" credit rating category.

In November 2022, the OEB approved HOI's first Joint Rate Application for 2023 to 2027 transmission revenue requirement and distribution rates. The approved settlement agreement, which was largely based on a continuation of the previous Custom Incentive Rate-making framework, provides the Company with certainty of funding for its substantial capital expenditures (capex) program over the next five years. DBRS Morningstar notes that the Province has since directed HOI to develop additional transmission projects, such as the $1.2 billion Waasigan Transmission Line. As such, annual capex over the next five years is expected to average over $2.7 billion, up from $2.1 billion in 2022.

While HOI's financial risk assessment remains reasonable, the Company's key credit metrics may see pressure over the next few years because of the large capex spend. DBRS Morningstar expects HOI 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" credit rating category. However, a negative credit rating action may occur should key metrics weaken to a level that no longer supports the current credit ratings (i.e. debt-to-capital above 60% and cash flow-to-debt below 12.5% for a sustained period).
