Moody’s Upgrades NorthWestern Corporation’s Senior Secured Credit Ratings

SIOUX FALLS, S.D., Aug. 4 /PRNewswire-FirstCall/ — NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE) today announced that Moody’s Investors Service has upgraded NorthWestern’s senior secured debt ratings from Baa1 to A3.

Moody’s cited as a reason for its upgrade an analysis that indicates regulated utilities have defaulted at a lower rate and experienced lower loss given default rates than non-financial, non-utility corporate issuers. Accordingly, Moody’s has upgraded the majority of senior secured debt ratings of investment-grade regulated utilities by one notch.

NorthWestern is rated investment grade on all senior secured and unsecured debt with Moody’s, Standard and Poor’s Ratings Services, and Fitch Ratings.
