DBRS Limited (DBRS Morningstar) confirmed the Issuer Rating and Unsecured Debentures rating of ENMAX Corporation (ENMAX or the Company) at BBB (high) and the Commercial Paper rating at R-2 (high). All trends are Stable. ENMAX's ratings are based on the Company's regulated electricity distribution and transmission businesses in the Province of Alberta (rated AA (low) with a Stable trend by DBRS Morningstar) and the State of Maine, offset by its higher-risk nonregulated electricity generation business. The Stable trends reflect ENMAX's reasonable financial risk assessment, which, given the mix of regulated and nonregulated operations, is supportive of the current ratings.

ENMAX's business risk assessment remained stable in 2021 and the first half of 2022. Following the acquisition of Versant Power in March 2020, regulated operations are targeted to contribute, on average, 70% of annual earnings, with the remaining contributed by the nonregulated business. In 2021, the Alberta Utilities Commission (AUC) finalized the 2022 deemed equity and return on equity for Alberta regulated utilities at 37% and 8.5%, unchanged from the previous year. The AUC also approved the Company's negotiated settlement for 2023 distribution rates; this serves as a one-year cost-of-service rebasing year before the third generation of the performance-based regulation plan. Additionally, the Maine Public Utilities Commission approved a 17.5% rate increase for Versant Power effective November 1, 2021, as well as a new decoupling mechanism. Given these regulatory decisions, DBRS Morningstar expects ENMAX's earnings and cash flows to remain steady and predictable through at least 2023.

ENMAX's key credit metrics strengthened modestly in 2021 and the last 12 months ended March 31, 2022, largely because of a full year's contribution from Versant Power, stronger results from the nonregulated generation segment, and the Company executing its plan to deleverage and reduce the debt issued for the Versant Power acquisition. ENMAX's key credit metrics remained in line with the BBB rating category. However, a negative rating action may occur if the metrics, considering the mix of regulated and nonregulated operations, weaken to a level no longer supportive of the current ratings. A negative rating action could also occur if significant investments are made in the nonregulated businesses that lead to a material shift in the earnings mix. Given the current financial risk assessment, DBRS Morningstar considers a positive rating action unlikely at this time.

There were no Environmental/Social/Governance (ESG) factors that had a significant or relevant effect on the credit analysis.
