Prompt Action Requested! Dear Stockholder: You are cordially invited to attend the Special Meeting of Stockholders of Goldman Sachs Middle Market Lending Corp. II (“MMLC II”) to be held virtually on October 8, 2025 at 10:00 a.m., Eastern Time. On July 11, 2025, MMLC II announced that it entered into a definitive merger agreement with Goldman Sachs Private Credit Corp., a Delaware Corporation (“GSCR”), and Goldman Sachs Asset Management, L.P., a Delaware limited partnership (the “Merger Agreement”), to merge with GSCR, with GSCR as the surviving company (the “Merger”). MMLC II’s board of directors (the “MMLC II Board”) and a committee of the MMLC II Board comprised solely of certain independent directors of MMLC II (the “MMLC II Special Committee”) weighed various benefits in considering the Merger, including: • each share of MMLC II common stock outstanding at the effective time of the Merger will receive an amount of cash equal to MMLC II’s net asset value per share, which provides immediate liquidity to MMLC II’s stockholders; • the Merger provides an efficient exit strategy for MMLC II and certainty of value to MMLC II’s stockholders; and • the MMLC II Board and the MMLC II Special Committee considered various exit alternatives and determined the Merger would be more beneficial to MMLC II’s stockholders. After careful consideration, the MMLC II Board, upon recommendation of the MMLC II Special Committee, unanimously recommends that MMLC II stockholders vote “FOR” the merger proposal. By voting FOR this proposal, you are helping MMLC II to realize several critical benefits.
