On June 3, 2024, Golub Capital BDC, Inc., a Delaware corporation (“GBDC”), completed its previously announced acquisition of Golub Capital BDC 3, Inc., a Maryland Corporation (the “Company”), pursuant to that certain Agreement and Plan of Merger (as amended, the “Merger Agreement”), dated as of January 16, 2024, by and among the Company, GBDC, Park Avenue Subsidiary Inc., a Maryland corporation and wholly owned subsidiary of GBDC (“Merger Sub”), GC Advisors LLC, a Delaware limited liability company and investment adviser to each of the Company and GBDC (“GC Advisors”), and, for certain limited purposes, Golub Capital LLC. Pursuant to the Merger Agreement, Merger Sub was first merged with and into the Company, with the Company as the surviving corporation (the “Initial Merger”), and, immediately following the Initial Merger, the Company was then merged with and into GBDC, with the GBDC as the surviving company (the Initial Merger and the subsequent merger, collectively, the “Merger”). As a result of, and as of the effective time of, the Merger, the Company’s separate existence ceased.

In accordance with the terms of the Merger Agreement, at the effective time of the Merger, each outstanding share of the Company’s common stock was converted into the right to receive 0.9138 shares of GBDC’s common stock (with the Company’s stockholders receiving cash in lieu of fractional shares of GBDC’s common stock). As a result of the Merger, GBDC will issue an aggregate of approximately 92,115,308 shares of its common stock to former stockholders of the Company prior to any adjustment for the former stockholders of the Company receiving cash in lieu of fractional shares.

The foregoing description of the Merger Agreement is a summary only and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which was filed by the Company as Exhibit 2.1 to its Current Report on Form 8-K filed on January 17, 2024, and Amendment No. 1 to the Agreement and Plan of Merger, a copy of which was filed by GBDC as Exhibit 4(b) to Amendment No. 1 to its Registration Statement on Form N-14 filed on April 12, 2024, both of which are incorporated herein by reference.

The information required by Item 3.03 is contained in Items 2.01 and is incorporated herein by reference.

The information required by Item 5.01 is contained in Item 2.01 and is incorporated herein by reference.

Pursuant to the Merger Agreement, each of the named executive officers and directors of the Company ceased to be named executive officers and directors of the Company as of the effective time of the Merger (and not because of any disagreement with the Company on any matter relating to the Company’s operations, policies, or practices).

On June 2, 2024, in accordance with the terms of the Merger Agreement, the Company’s board of directors declared a distribution of $0.0944 per share, which is payable on June 6, 2024 to stockholders of record on June 2, 2024.
