MIC Notes S&P Downgrade to BB+ / Stable

Macquarie Infrastructure Corporation (NYSE:MIC) notes that S&P Global Ratings’ (S&P) today downgraded MIC’s Issuer Credit Rating to BB+ / Stable from BBB- / Negative Outlook. S&P simultaneously downgraded MIC’s International-Matex Tank Terminals (IMTT) subsidiary to reflect the change in the parent rating.

Christopher Frost, Chief Executive Officer of MIC, made the following statement:

"The successful sales of the Bayonne Energy Center and other, smaller businesses in 2018, together with the pending sales of our portfolio of wind and solar power generation businesses, have sharpened our strategic focus and strengthened our balance sheet although modestly reduced the diversity of our cash flows. Taken together with the decreased contribution from IMTT while repurposing and repositioning investments continue, S&P has concluded that MIC should be rated under S&P's corporate methodology and that a one-notch downgrade is appropriate.

"As previously noted, we do not expect the ratings revision or change in ratings methodology to have any material impact on our interest expense or our financial condition. We have ample liquidity with which to fund our commitments, including our dividend, and expect to maintain our ratio of net debt to EBITDA in a range of between 4- and 4.25-times in 2019. Importantly, the majority of our debt facilities do not require refinancing before 2025.”
