In addition, the furnishing of this Item 7.01 of Form 8-K and Exhibit 99.1 will not be deemed an admission that such information includes material information that is not otherwise publicly available.

Forward-Looking Statements

The information in this Current Report includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target,” “result,” “follow,” “to be,” “extend,” “shall,” “may” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of financial and performance metrics, projections of market opportunity and market share, expectations and timing related to commercial product launches, potential benefits of the transaction and expectations related to the terms and timing of the transaction. These statements are based on various assumptions, whether or not identified in this Current Report, and on the current expectations of Oculis’s and EBAC’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of Oculis and EBAC. These forward-looking statements are subject to a number of risks and uncertainties, including changes in domestic and foreign business, market, financial, political and legal conditions; the inability of the parties to successfully or timely consummate the proposed business combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business combination or that the approval of the shareholders of Oculis or EBAC is not obtained; changes to the proposed structure of the proposed business combination that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the proposed business combination; the risk that the proposed business combination disrupts current plans and operations of Oculis as a result of the announcement and consummation of the proposed business combination; failure to realize the anticipated benefits of the proposed business combination; risks relating to the uncertainty of the projected financial information with respect to Oculis; the ability for Oculis Holding AG (“New Parent”) to meet stock exchange listing standards following the consummation of the proposed business combination; future global, regional or local economic and market conditions; the development, effects and enforcement of laws and regulations; Oculis’s ability to manage future growth; the effects of competition on Oculis’ future business; the amount of redemption requests made by EBAC’s public shareholders; the ability of EBAC or the combined company to issue equity or equity-linked securities in connection with the proposed business combination or in the future; the outcome of any potential litigation, government and regulatory proceedings, investigations and inquiries against Oculis or EBAC; and those factors discussed in EBAC’s Quarterly Report on Form 10-Q for the period ended June 30, 2022, under the heading “Risk Factors” filed with the SEC on August 15, 2022, its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 under the heading “Risk Factors,” the registration statement on Form F-4 filed by New Parent with the SEC (Registration No. 333-268201) (the “Registration Statement”) under the heading “Risk Factors” and other documents of EBAC filed, or to be


filed, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither EBAC nor Oculis presently know or that EBAC nor Oculis currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect EBAC’s or Oculis’s expectations, plans or forecasts of future events and views as of the date of this Current Report. EBAC and Oculis anticipate that subsequent events and developments will cause EBAC’s or Oculis’s assessments to change. However, while EBAC and Oculis may elect to update these forward-looking statements at some point in the future, EBAC and Oculis specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing EBAC’s or Oculis’s assessments as of any date subsequent to the date of this Current Report. Accordingly, undue reliance should not be placed upon the forward-looking statements.
