STWO has commenced mailing of the Proxy Statement/Prospectus, which contains a notice and voting instruction form or a proxy card relating to the Extraordinary General Meeting to STWO shareholders of record as of the close of business on the record date of August 16, 2021.

STWO encourages shareholders to vote by submitting their proxies as soon as possible, and by no later than 11:59 PM Eastern Time on October 4, 2021, after carefully reading the Proxy Statement/Prospectus, to ensure that the shareholder’s shares will be represented at the Extraordinary General Meeting.

These forward-looking statements are based on STWO’s and ESS’ current expectations and beliefs concerning future developments and their potential effects on STWO, ESS or any successor entity of the proposed transactions. Many factors could cause actual future events to differ materially from the forward-looking statements in this presentation, including but not limited to: (i) the risk that the proposed transactions may not be completed in a timely manner or at all, which may adversely affect the price of STWO’s securities, (ii) the failure to satisfy the conditions to the consummation of the proposed transactions, (iii) the occurrence of any event, change or other circumstance that could give rise to the termination of the business combination, (iv) the effect of the announcement or pendency of the proposed transactions on ESS’ business relationships, operating results and business generally, (v) risks that the proposed transactions disrupt current plans and operations of ESS, (vi) changes in the competitive and highly regulated industries in which ESS plans to operate, variations in operating performance across competitors, changes in laws and regulations affecting ESS’ business and changes in the combined capital structure and (vii) the ability to implement business plans, forecasts and other expectations after the completion of the proposed transactions, and identify and realize additional opportunities. There can be no assurance that the future developments affecting STWO, ESS or any successor entity of the proposed transactions will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond STWO’s or ESS’ control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of STWO’s registration statement on Form S-1 (File No. 333-248515), the registration statement on Form S4 (File No. 333-257232) filed in connection with the business combination, and other documents filed by STWO from time to time with the SEC.

Except as required by law, STWO and ESS are not undertaking any obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise. Neither STWO nor ESS gives any assurance that either the STWO or ESS, or the combined company, will achieve its expectations.
