Goldman Sachs BDC, Inc. Announces Public Reopening of Unsecured Convertible Notes

Company Release – June 27, 2018

NEW YORK - (BUSINESS WIRE) - Goldman Sachs BDC, Inc. (the “Company”) (NYSE: GSBD) announced today that it plans to conduct an offering of $32.5 million aggregate principal amount of its 4.50% convertible notes due 2022 (the “Convertible Notes”). The Convertible Notes will have identical terms, be fungible with and be a part of a single series of convertible debt securities with the outstanding $115 million aggregate principal amount of the Company’s 4.50% Convertible Notes due 2022 issued in September 2016 in a private offering.

The completion of the proposed offering depends upon several factors, including market and other conditions.

The Convertible Notes are unsecured and bear interest at a rate of 4.50% per year, payable semiannually. In certain circumstances, the Convertible Notes will be convertible into cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election. The Company will not have the right to redeem the Convertible Notes prior to maturity. The Convertible Notes will mature on April 1, 2022, unless repurchased or converted in accordance with the terms prior to such date.

The Company intends to use the net proceeds of this offering to pay down debt under its revolving credit facility.

SunTrust Robinson Humphrey, BofA Merrill Lynch, Morgan Stanley and Goldman Sachs & Co. LLC are acting as joint book-running managers for this offering.
