Boston Properties, Inc. (NYSE: BXP), the largest publicly-traded developer, owner and manager of Class A office properties in the United States, announced today that its operating partnership, Boston Properties Limited Partnership (“BPLP”), has agreed to sell $700.0 million of 2.900% senior unsecured notes due 2030 in an underwritten public offering through BofA Securities, Inc., Citigroup Global Markets Inc., Deutsche Bank Securities Inc., J.P. Morgan Securities LLC, Wells Fargo Securities, LLC, BNY Mellon Capital Markets, LLC, Jefferies LLC, Morgan Stanley & Co. LLC, SunTrust Robinson Humphrey, Inc., TD Securities (USA) LLC and U.S. Bancorp Investments, Inc., as joint book-running managers. The notes were priced at 99.954% of the principal amount to yield 2.905% to maturity. The notes will mature on March 15, 2030, unless earlier redeemed. The offering is expected to close on September 3, 2019, subject to the satisfaction of customary closing conditions.

The estimated net proceeds from this offering are expected to be approximately $693.8 million. BPLP intends to use the net proceeds from the sale of the notes to fund the redemption of the $700.0 million aggregate principal amount of its outstanding 5.625% senior notes that are scheduled to mature on November 15, 2020 (the “2020 Notes”). Following the pricing of the offering, BPLP delivered notice to the trustee that it exercised its right to redeem the 2020 Notes on September 18, 2019. Pending such use, BPLP may invest the net proceeds in short-term, interest-bearing deposit accounts.

In connection with the redemption of the 2020 Notes, BPLP estimates that it will recognize a loss of approximately $0.17 per diluted share in the third quarter of 2019 related to the early extinguishment of debt. In addition, the Company estimates the refinancing will reduce 2019 diluted FFO per share by approximately $0.14 per share, reflecting the loss on early extinguishment of debt, interest savings associated with this refinancing and interest earned on the net proceeds of the offering pending the redemption. Neither this offering nor the impact of the redemption of the 2020 Notes was previously reflected in Boston Properties’ earnings guidance for third quarter or full year 2019.
