S&P Global Ratings upgraded Potlatch Corp.'s corporate credit rating to BB+ from BB, with a stable outlook.
In addition, the rating agency lifted the issue-level rating on the company's senior unsecured debt to BB+ from BB.
According to a note, the upgrade takes into account the substantial improvement in the company's earnings, EBITDA generation and credit measures over the prior year, owing mainly to improvement in lumber pricing and demand for the timber and wood products producer.
The stable outlook reflects S&P's view that even with some volatility in lumber pricing, the company will preserve debt leverage in the 3x area over 2018.
