&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• [Registration Statement No. 333-231816](https://www.sec.gov/Archives/edgar/data/1600626/000160062619000142/gcear2-formsx8forltip52019.htm) , filed with the SEC on May 30, 2019, registering a total
 of 6,935,314 shares of the Registrant's Common Shares under the Employee and Director Long-Term Incentive Plan of Griffin Capital Essential Asset REIT II, Inc. , as amended by [Post-Effective Amendment No. 1](https://www.sec.gov/Archives/edgar/data/1600626/000160062620000127/gcear-formsx8posforamended.htm) to the Registration Statement, filed with the SEC on June 17, 2020, registering a reduction in

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• [Registration Statement No. 333-287651](https://www.sec.gov/Archives/edgar/data/1600626/000114036125020787/ef20049864_s8.htm) , filed with the SEC on May 29, 2025, registering a total of 2,068,168
 shares of the Registrant's Common Shares under the Peakstone Realty Trust Second Amended and Restated Employee and Trustee Long-Term Incentive Plan .

On May 6, 2026, the Registrant completed the transactions contemplated by the Agreement and Plan of Merger (the "<u>Merger Agreement</u>"), dated as of February 2, 2026, by and among BSREP V Neon Pooling REIT L.P., BSREP V Neon Pooling Non-REIT L.P. and BSREP V Brookfield Neon Sub L.P., each a Delaware limited partnership (collectively, "<u>Parent</u>"), Neon REIT Merger Sub LLC, a Delaware limited liability company and a subsidiary of Parent ("<u>REIT Merger Sub</u>"), Neon OP Merger Sub LLC, a Delaware limited liability company and a subsidiary of Parent ("<u>Operating Merger Sub</u>"), the Registrant and PKST OP, L.P., a Delaware limited partnership and a majority owned subsidiary of the Registrant (the "Operating Partnership"). Pursuant to the Merger Agreement, at the closing of the transactions contemplated thereunder, (i) Operating Merger Sub merged with and into the Operating Partnership, with the Operating Partnership surviving the merger (the "<u>Surviving Partnership</u>" and such merger, the "<u>Partnership Merger</u>"), and (ii) immediately following the consummation of the Partnership Merger, REIT Merger Sub merged with and into the Registrant, with the Registrant surviving the merger (the "<u>Surviving Entity</u>" and such merger, together with the Partnership Merger, the "<u>Mergers</u>").
