This communication contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements are based on Proofpoint’s current expectations, estimates and projections about the potential benefits of the transaction, its business and industry, management’s beliefs and certain assumptions made by Proofpoint and Thoma Bravo, all of which are subject to change. In this context, forward-looking statements often address expected future business and financial performance and financial condition, and often contain words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “could,” “seek,” “see,” “will,” “may,” “would,” “might,” “potentially,” “estimate,” “continue,” “expect,” “target,” similar expressions or the negatives of these words or other comparable terminology that convey uncertainty of future events or outcomes. All forward-looking statements by their nature address matters that involve risks and uncertainties, many of which are beyond our control, and are not guarantees of future results, such as statements about the anticipated benefits of the transaction. These and other forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially from those expressed in any forward-looking statements. Accordingly, there are or will be important factors that could cause actual results to differ materially from those indicated in such statements and, therefore, you should not place undue reliance on any such statements and caution must be exercised in relying on forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: (i) the impact of the COVID-19 pandemic on Proofpoint’s business and general economic conditions; (ii) Proofpoint’s ability to implement its business strategy; (iii) potential litigation relating to the transaction; (iv) the risk that disruptions from the transaction will harm Proofpoint’s business, including current plans and operations; (v) the ability of Proofpoint to retain and hire key personnel; (vi) potential adverse reactions or changes to business relationships resulting from the completion of the transaction; (vii) legislative, regulatory and economic developments affecting Proofpoint’s business; (viii) general economic and market developments and conditions; (ix) the evolving legal, regulatory and tax regimes under which Proofpoint operates; and (x) unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as Proofpoint’s response to any of the aforementioned factors. These risks, as well as other risks associated with the transaction, are more fully discussed in the proxy statement filed with the U.S. Securities and Exchange Commission in connection with the transaction. While the list of factors presented here is, and the list of factors presented in the proxy statement is, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on Proofpoint’s financial condition, results of operations, or liquidity.
