Boston Properties Prices $1.0 Billion Offering of Green Bonds

Boston Properties, Inc. (NYSE: BXP), one of the largest publicly-traded developers, owners and managers of Class A office properties in the United States, announced today that its operating partnership, Boston Properties Limited Partnership (“BPLP”), has agreed to sell $1.0 billion of 4.500% senior unsecured notes due 2028 in an underwritten public offering through Deutsche Bank Securities Inc., J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner& Smith Incorporated, Morgan Stanley & Co. LLC, BNY Mellon Capital Markets, LLC, Citigroup Global Markets Inc., Jefferies LLC, Scotia Capital (USA) Inc., SunTrust Robinson Humphrey, Inc., TD Securities (USA) LLC, U.S. Bancorp Investments, Inc., as joint book-running managers. The notes were priced at 99.641% of the principal amount to yield 4.545% to maturity. The notes will mature on December 1, 2028, unless earlier redeemed. The offering is expected to close on November 28, 2018, subject to the satisfaction of customary closing conditions. The estimated net proceeds from this offering are expected to be approximately $988.1 million. BPLP intends to allocate an amount equal to the net proceeds from this offering to the financing and refinancing of recently completed and future eligible green projects in the United States, including the Salesforce Tower development project in San Francisco, California, which has received LEED Platinum certification. BPLP currently owns and actively manages over 20 million square feet of green building projects that have been certified at the highest LEED Gold and LEED Platinum levels. BPLP actively works to promote its growth and operations in a sustainable and responsible manner and has earned seven consecutive Global Real Estate Sustainability Benchmark (GRESB) Green Stars and the highest GRESB 5-star Rating. BPLP intends to initially use the net proceeds from this offering for the repayment of debt, including funding the redemption of the 5.875% senior notes due 2019 that are scheduled to mature on October 15, 2019 (the “2019 Notes”) and, for any net proceeds from this offering not used to fund the redemption of the 2019 Notes, repaying borrowings outstanding under its unsecured revolving line of credit. Pending such uses, BPLP may invest the proceeds in short-term, interest-bearing, investment-grade securities. In connection with the redemption of the 2019 Notes, BPLP expects that it will record a loss from early extinguishment of debt in the fourth quarter of 2018. Neither this offering nor the impact of the redemption of the 2019 Notes was previously reflected in Boston Properties’ earnings guidance for 2018 or 2019.
