Transaction Overview

On May 9, 2023, RMG III entered into a definitive agreement to combine with H2B2. The base purchase price of $750,000,000 is subject to adjustment based on the results of the proposed capital raise transaction described below. H2B2 is separately undertaking a capital raise transaction, which is expected to close prior to the Proposed Transaction. The capital raise transaction is being led by Natixis Partners Iberia S.A. and BCW Securities LLC, an affiliate of RMG III. Subject to the terms and conditions of the merger agreement for the business combination, post-capital raise transaction stockholders of H2B2 will roll 100% of their equity into the surviving corporation.

The boards of directors of RMG and H2B2 have both unanimously approved the Proposed Transaction. The sponsor of RMG III and stockholders representing a majority of the outstanding shares of common stock of H2B2 have entered into support agreements agreeing to vote in favor of the Proposed Transaction, which is expected to be approved by H2B2’s stockholders by mid-June. The Proposed Transaction is further conditioned upon the consummation of a capital raise transaction of at least $40 million, the completion of a cashless warrant exchange by RMG III and certain other customary closing conditions, including the approval by RMG’s shareholders and certain governmental and regulatory approvals. The parties expect the Proposed Transaction to close in the second half of 2023.

To maximize future public market performance by simplifying the capital structure and removing future share price overhang, RMG III intends to convert all the public and private placement warrants into newly issued common stock of the surviving corporation. There will be a proposal to all public and private placement warrant holders for the conversion of each warrant into a newly issued common stock of the surviving corporation, at a ratio of 0.075x in common stock of the surviving corporation.

Upon the closing of the Proposed Transaction, the surviving corporation will be named “H2B2 Electrolysis Technologies, Inc.”, and its shares of common stock of the surviving corporation are expected to be listed on the Nasdaq Capital Market.
