(Poseida) (NASDAQ: PSTX) at a price of $9.00 per share in cash, plus a non-tradeable contingent value right (CVR) to receive certain contingent payments of up to an aggregate of $4.00 per share in cash. The tender offer is being made pursuant to the previously announced merger agreement dated as of November 25, 2024 among Roche Holdings, Inc., an indirect wholly owned subsidiary of Roche Holding Ltd, Blue Giant Acquisition Corp., a wholly owned subsidiary of Roche Holdings, Inc., and Poseida.

Cautionary Statement Regarding Forward-Looking Statements

This communication may include statements that are not statements of historical fact, or “forward-looking statements,” within the meaning of the federal securities laws, including with respect to Roche’s proposed acquisition of Poseida. Any express or implied statements that do not relate to historical or current facts or matters are forward-looking statements. These statements are generally identified by words or phrases such as “believe”, “anticipate”, “expect”, “intend”, “plan”, “will”, “may”, “should”, “estimate”, “predict”, “project”, “strategy”, “potential”, “continue” or the negative of such terms or other similar expressions. Such statements include, but are not limited to, the ability of Roche and Poseida to complete the transactions contemplated by the merger agreement, including each party’s ability to satisfy the conditions to the consummation of the offer contemplated thereby and the other conditions set forth in the merger agreement and statements about the expected timetable for completing the transaction. These statements are based upon the current beliefs and expectations of Roche and Poseida’s management and are subject to significant risks and uncertainties. There can be no guarantees that the conditions to the closing of the proposed transaction will be satisfied on the expected timetable if at all. If underlying assumptions prove inaccurate or risks or uncertainties materialize, actual results may differ materially from those set forth in the forward-looking statements, and you should not place undue reliance on these statements. Risks and uncertainties include, but are not limited to, uncertainties as to the timing of the offer and the subsequent merger; uncertainties as to how many of Poseida’s stockholders will tender their shares in the offer; the risk that competing offers or acquisition proposals will be made; the possibility that various conditions to the consummation of the offer and the merger contemplated by the merger agreement may not be satisfied or waived, including that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the tender offer or the subsequent merger; the ability to obtain necessary regulatory approvals or to obtain them on acceptable terms or within expected timing; the effects of disruption from the transactions contemplated by the merger agreement and the impact of the announcement and pendency of the transactions on Poseida’s business; the possibility that the milestone payments related to the contingent value right will never be achieved and that no milestone payment may be made; and the risk of legal proceedings being brought in relation to the transactions and the outcome of such proceedings, including the risk that stockholder litigation in connection with the offer or the merger may result in significant costs of defense, indemnification and liability. The foregoing factors should be read in conjunction with the risks and cautionary statements discussed or identified in Poseida’s public filings with the SEC, including the “Risk Factors” section of Poseida’s Annual Report on Form 10-K for the year ended December 31, 2023 and subsequent Quarterly Reports on Form 10-Q, Form 8-K and in other filings Poseida makes with the SEC from time to time as well as the tender offer materials to be filed by Roche and its acquisition subsidiary and the Solicitation/Recommendation Statement to be filed by Poseida, in each case as amended by any subsequent filings made with the SEC. Neither Roche nor Poseida undertakes any obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by law.
