The upgrade to BB+ reflects the expectation that the revenue growth and EBITDA margin strength in recent years will continue. S&P calculated leverage was 2.1x, and an upgrade to investment grade would require S&P to view the leverage as sustainable at 1.5x. We do not think that is likely over the next two years, so we expect the rating to remain at BB+.
