MaxCyte Regulatory News (MXCT)

Publication of Stockholder Circular and Notice of Special Meeting

Gaithersburg, Maryland - 16 June 2021: MaxCyte (LSE: MXCT, MXCN), a leading provider of platform technologies for cell engineering, today announced that it has published a stockholder circular (the "Circular") to convene a Special Meeting to be held on 6 July 2021 at 1 p.m. BST (8 a.m. EST) at the offices of MaxCyte, Inc., 21 Firstfield Road, Suite 202, Gaithersburg, Maryland 20878, US. The Special Meeting will consider certain resolutions in connection with the Company's proposed US-registered public offering of shares of Common Stock and dual-listing of the Common Stock on Nasdaq (the "Proposed Offering").

This Special Meeting follows the Company announcement on 14 May 2021, that it had confidentially submitted a draft registration statement on Form S-1 to the SEC relating to a proposed dual-listing and public offering of shares of Common Stock on Nasdaq. The exact timing of the Proposed Offering as well as the number of and the price of the shares of Common Stock to be offered and sold in the Proposed Offering have not yet been determined. The Proposed Offering is subject to the Securities and Exchange Commission satisfactorily completing its review of the Company's registration statement related thereto in addition to market and other conditions. There is no assurance that the Proposed Offering will be completed, nor is there certainty as to the timing of the Proposed Offering.

In particular, the Circular includes a resolution ("Resolution 1") which will, if passed, waive the pre-emptive rights of Stockholders in order for MaxCyte to be able to issue new Common Stock in the Proposed Offering. An affirmative vote of at least 75 percent of the voting power of the shares of Common Stock voted at the Special Meeting is required to approve Resolution 1. The proposed disapplication of pre-emptive rights in Resolution 1 is necessary to allow the Proposed Offering to proceed.

If Resolution 1 is passed and the Proposed Offering proceeds, the Directors intend to maintain the admission of the shares of Common Stock to trading on AIM alongside listing of the shares of Common Stock on Nasdaq. Accordingly, Stockholders will continue to be able to deal in shares of Common Stock on AIM and, in due course, may also deal in shares of Common Stock on Nasdaq. The Company will continue to be subject to the AIM Rules for Companies.

If Resolution 1 is not passed, the Proposed Offering will not proceed.

Further detail on Resolution 1 and all other proposed resolutions and the reasons for each are included in the Circular, which has today been sent to Shareholders and is available on the Company's website at https://investors.maxcyte.com/news-events/documents-presentations.

The Company intends to provide further details in due course in an announcement to be made via a Regulatory Information Service as to how, subject to completion of the Proposed Offering, Stockholders will be able to move shares of Common Stock between the UK and the US.
