Item 8.01 – Other Events.

On March 22, 2016, the Board of Directors of Goldman Sachs BDC, Inc. (the “Company”) determined that the 2016 Annual Meeting of Stockholders (the “Annual Meeting”) will be held on May 3, 2016, at 3:30 p.m. (Eastern time). The Board also established the close of business on April 4, 2016 as the record date for determining stockholders of the Company entitled to notice of and to vote at the Annual Meeting. At the Annual Meeting, the Company’s stockholders will be asked to vote to elect three Class II directors of the Company who will each serve until the Company’s 2019 Annual Meeting of Stockholders or until his or her successor is duly elected and qualified and to authorize the Company, with the approval of the Company’s Board of Directors, to sell or otherwise issue shares of the Company’s common stock (during the 12 months following such authorization) at a price below the then-current net asset value per share, subject to certain limitations.

Because the Annual Meeting will be held more than 30 calendar days from the anniversary of the Company’s 2015 Annual Meeting of Stockholders, the Company has established a new deadline by which a stockholder proposal must be submitted to the Company for inclusion in the Company’s proxy materials for the Annual Meeting. In order to be considered for inclusion in the Company’s proxy materials, stockholder proposals must be received at the Company’s principal executive offices at Goldman Sachs BDC, Inc., c/o Goldman Sachs Asset Management, L.P., 200 West Street, New York, New York 10282, Attn: Corporate Secretary no later than the close of business on April 1, 2016. The submission of a proposal does not guarantee its inclusion in the Company’s proxy statement or presentation at the meeting unless certain securities law requirements are met.

Additionally, in accordance with the advance notice provisions set forth in the Company’s bylaws, in order for other business to be brought before the Annual Meeting (including nomination of a director), a notice of intention to present the proposal must be received at the Company’s principal executive offices no later than April 2, 2016, and must also comply with the provisions set forth in the Company’s bylaws and applicable law.

The Company reserves the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with applicable requirements.
