DBRS Morningstar Confirms Ratings on Inter Pipeline Ltd. at BBB (low) and BB With Stable Trends

November 15, 2022

DBRS Limited (DBRS Morningstar) confirmed the ratings on Inter Pipeline Ltd. (IPL or the Company) at BBB (low) and BB. All trends are Stable. The rating confirmations reflect the Company’s strong business risk profile underpinned by contracted cost of service- (COS) and fee-based contracts and a diversified asset base. The key challenge to the ratings remains the commissioning and start-up risk at the Heartland Petrochemical Complex (HPC). The Stable trend reflects DBRS Morningstar’s expectation that once the HPC is fully operational, the Company’s credit metrics will improve and that Brookfield Infrastructure Partners L.P. and its institutional partners (together, Brookfield Infrastructure) will maintain IPL’s credit metrics at a level commensurate with the current ratings.

The HPC achieved two major milestones in 2022 with the commissioning of the polypropylene plant in June 2022 and the propane dehydrogenation plant in October 2022. Production from the HPC is expected to ramp up in Q4 2022 and in 2023. Nevertheless, ramping up production at a new and large petrochemical plant is a complicated process and a material delay or under-performance could have a negative impact on the Company's credit risk profile.

Earnings as of the nine months ended September 30, 2022, (9M 2022) were higher relative to 9M 2021 across IPL's business segments. The Long-Haul Pipeline business (51% of 9M 2022 EBITDA) benefitted from higher interest rates. The business operates under COS contracts where returns are directly linked to long-term Government of Canada bond rates. The COS contracts also mitigate the impact of inflation by passing on increases in costs to primarily investment-grade counterparties. In addition, higher commodity prices had a material impact on earnings, especially at the Marketing segment. Higher earnings combined with lower capital expenditure (capex) at the HPC, and the absence of dividend payments allowed IPL to generate a modest free cash flow (FCF; i.e., cash flow after capex) in 9M 2022 and a modest increase in debt. Consequently, the Company's modified consolidated (treating Inter Pipeline (Corridor) Inc., rated A (low) with a Stable trend by DBRS Morningstar, as an equity investment) cash flow-to-debt ratio improved in 9M 2022 compared with YE 2021.

While earnings from the Marketing segment in 2023 is expected to be tempered by lower commodity prices, DBRS Morningstar expects overall earnings and cash flow to be materially higher in 2023 because of the ramp-up in production at the HPC. DBRS Morningstar expects the credit metrics to continue to improve in 2023 and expects IPL to maintain its modified consolidated cash flow-to-debt ratio in excess of 15% once the HPC is fully operational. DBRS Morningstar notes post completion of the HPC, IPL's sustaining/growth capex requirements are modest relative to its cash flow, and expects IPL to generate a material FCF surplus. DBRS Morningstar expects Brookfield Infrastructure to manage its distribution policy in a manner consistent with maintaining IPL's key credit metrics at a level commensurate with the ratings.

DBRS Morningstar may consider a negative rating action if credit metrics weaken materially below DBRS Morningstar's expectation and/or IPL's business risk profile deteriorates materially. A positive rating action is unlikely until the HPC is fully operational and the credit metrics improve materially.
