DEREGISTRATION OF SECURITIES

These Post-Effective Amendments (the “Post-Effective Amendments”) relate to the following Registration Statements on Form S-8 (each, a “Registration Statement” and collectively, the “Registration Statements”) of Peakstone Realty Trust, Inc., a Maryland corporation (as successor-by-conversion to, and formerly known as, Peakstone Realty Trust, a Maryland real estate investment trust) (the “Registrant”), which have been previously filed with the Securities and Exchange Commission (the “SEC”), to deregister any and all shares of the Registrant’s common shares of beneficial interest, par value $0.001 per share (the “Registrant’s Common Shares”), registered but unsold or otherwise unissued under each such Registration Statement as of the date hereof:

•

Registration Statement No. 333-231816, 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 to the Registration Statement, filed with the SEC on June 17, 2020, registering a reduction in the number of the Registrant’s Common Shares available for issuance under the Griffin Capital Essential Asset REIT, Inc. Amended and Restated Employee and Director Long-Term Incentive Plan by 3,000,000 of the Registrant’s Common Shares;

•

Registration Statement No. 333-280527, filed with the SEC on June 27, 2024, registering a total of 1,322,448 shares of the Registrant’s Common Shares under the Peakstone Realty Trust Second Amended and Restated Employee and Trustee Long-Term Incentive Plan; and

•

Registration Statement No. 333-287651, 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 “Merger Agreement”), 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, “Parent”), Neon REIT Merger Sub LLC, a Delaware limited liability company and a subsidiary of Parent (“REIT Merger Sub”), Neon OP Merger Sub LLC, a Delaware limited liability company and a subsidiary of Parent (“Operating Merger Sub”), 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 “Surviving Partnership” and such merger, the “Partnership Merger”), 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 “Surviving Entity” and such merger, together with the Partnership Merger, the “Mergers”). As a result of the Mergers, Parent (or subsidiaries thereof) became the sole common shareholders of the Surviving Entity, and the Surviving Partnership became wholly owned by Parent and the Surviving Entity (or subsidiaries thereof). On May 6, 2026, following the closing of the Mergers, the Registrant converted to a Maryland corporation and became known as Peakstone Realty Trust, Inc.

As a result of the Mergers, the Registrant has terminated any and all offerings of its securities pursuant to the Registration Statements. Accordingly, the Registrant hereby terminates the effectiveness of each Registration Statement and, in accordance with an undertaking made by the Registrant in Part II of each Registration Statement to remove from registration, by means of post-effective amendment, any securities that had been registered for issuance but remain unsold or otherwise unissued at the termination of the offering, removes from registration any and all securities of the Registrant registered but unsold or otherwise unissued under the Registration Statements as of the date hereof.
