ISS Recommends Shareholders VOTE FOR the GSE Merger

COLUMBIA, Md., Oct. 16, 2024 /PRNewswire/ -- GSE Solutions ("GSE Systems, Inc." or "GSE") (Nasdaq: GVP), a leader in advanced engineering solutions that supports the future of clean-energy production and decarbonization initiatives of the power industry, announced today that leading independent proxy advisory firm Institutional Shareholder Services, Inc. ("ISS") recommended that GSE shareholders vote "FOR": (1) the approval of the Agreement and Plan of Merger, dated as of August 8, 2024 (the "Merger Agreement"), by and between GSE, Nuclear Engineering Holdings LLC, and Gamma Nuclear Merger Sub LLC (the "Merger Proposal"); and (2) the approval, on a non-binding, advisory basis, of the compensation that may become payable to GSE's named executive officers in connection with the merger.

In its October 4, 2024 report, ISS noted:¹

• After obtaining $4.10 in cash at an approximately 50% premium to the unaffected market value of GSE stock, "[t]he cash form of consideration provides shareholders with liquidity and certainty of value. "
• After contacting 116 parties and running an arms-length auction process, "[t]he board appears to have conducted a reasonably thorough sales process, which was reinitiated following an unsolicited offer by a third party."

¹ Permission to use quotes neither sought nor obtained.

Kathryn O'Connor Gardner, Chair of the Board of GSE, stated, "The Board is pleased that ISS recognizes that this outcome is in the best interest of GSE shareholders. The Board is even more pleased that, of the proxies received to date, approximately 97% of shareholders see it the same way."
