DBRS Morningstar Assigns Rating of BBB (low), Stable Trend to AltaGas Ltd.’s $500 Million Medium-Term Notes

Utilities & Independent Power
June 10, 2020

DBRS Limited (DBRS Morningstar) assigned a rating of BBB (low) with a Stable trend to AltaGas Ltd.’s (AltaGas or the Company) $500 million 2.157% Medium-Term Notes issuance due June 10, 2025 (the Notes). The rating assigned to this newly issued debt instrument is based on the rating of an already-outstanding debt series of the above-mentioned debt instrument.

AltaGas intends to use the net proceeds from the Notes to pay down existing indebtedness including, without limitation, indebtedness under AltaGas’ credit facility, and for general corporate purposes.

AltaGas’ ratings reflect its diversified portfolio of regulated utilities and midstream business in the United States and Canada. The Company’s Utilities segment generates stable cash flows that are supported by natural gas distribution rates approved under cost-of-service models; however, structural subordination at AltaGas’ U.S. regulated utilities and earnings volatility and weaker counterparties in its Canadian Midstream segment weaken the Company’s credit profile.
