Item 5.07. Submission of Matters to a Vote of Security Holders.

On November 2, 2018, Goldman Sachs Middle Market Lending Corp. (the “Company”) held its annual meeting of stockholders (the “Annual Meeting”). At the Annual Meeting, stockholders considered two proposals as described in the Company’s proxy statement filed on September 6, 2018. The issued and outstanding shares of stock of the Company entitled to vote at the Annual Meeting consisted of 29,638,926 shares of common stock outstanding on the record date, September 5, 2018. The final results of the voting on the matters submitted to stockholders at the Annual Meeting are set forth below.

Proposal I: By the vote shown below, the stockholders elected the nominees for directors. Each director will serve until the 2019 annual meeting of stockholders and until his or her successor is duly elected and qualified. The election of each nominee required a majority of the votes cast by all stockholders present, in person or by proxy, at the Annual Meeting. Under the Company’s bylaws, a majority of votes cast means that the number of votes cast “for” a director’s election exceeds the number of votes cast “against” that director’s election (with “abstentions” and “broker non-votes” not counted as a vote cast either “for” or “against” that director’s election).

Proposal II: The stockholders also voted on a proposal to ratify the selection of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018. Approval of Proposal II required a majority of the votes cast by all stockholders present, in person or by proxy, at the Annual Meeting.
