HA Sustainable Infrastructure Capital (HASI) priced an offering of $1 billion in 5.95% green senior unsecured notes due 2033, the company said Tuesday.

The notes will be guaranteed by Hannon Armstrong Sustainable Infrastructure, Hannon Armstrong Capital and other affiliated companies, the company said.

The offering is expected to settle on June 24, HASI said.

HASI said it expects net proceeds of about $987 million, which it plans to use to temporarily repay a portion of the outstanding debt under its unsecured revolving credit facility or its commercial paper programs.

The company plans to use an amount equal to the net proceeds from the offering to acquire, invest in or refinance eligible green projects. Until the proceeds are fully invested in eligible green projects, HASI may invest the funds in interest-bearing accounts and short-term interest-bearing securities, it said.

Shares of HASI were up more than 1% in Tuesday pre-bell activity.
