Pfizer does not endorse TRC Capital Investment’s unsolicited mini-tender offer and recommends that stockholders do not tender their shares in response to TRC Capital Investment’s offer because the offer is at a price below the current market price for Pfizer’s shares and subject to numerous conditions. Pfizer is not affiliated or associated in any way with TRC Capital Investment, its mini-tender offer or its offer documentation.

TRC Capital Investment’s has made many similar mini-tender offers for shares of other companies. Mini-tender offers seek to acquire less than 5 percent of a company’s shares outstanding, thereby avoiding many disclosure and procedural requirements of the U.S. Securities and Exchange Commission (SEC) that apply to offers for more than 5 percent of a company’s shares outstanding. As a result, mini-tender offers do not provide investors with the same level of protections as provided for larger tender offers under U.S. securities laws.

The SEC has cautioned investors that some bidders making mini-tender offers at below-market prices are “hoping that they will catch investors off guard if the investors do not compare the offer price to the current market price.” More on the SEC’s guidance to investors on mini-tender offers is available at www.sec.gov/investor/pubs/minitend.htm.

Pfizer urges investors to obtain current market quotations for their shares, to consult with their broker or financial advisor and to exercise caution with respect to TRC Capital Investment’s offer. Pfizer recommends that stockholders who have not responded to TRC Capital Investment’s offer take no action. Stockholders who have already tendered their shares may withdraw them at any time prior to the expiration of the offer, in accordance with TRC Capital Investment’s offer documentation. The offer is currently scheduled to expire at 12:01 a.m., New York City time, on January 30, 2024. TRC Capital Investment may extend the offering period at its discretion.

Pfizer encourages brokers and dealers, as well as other market participants, to review the SEC’s letter regarding broker-dealer mini-tender offer dissemination and disclosure at www.sec.gov/divisions/marketreg/minitenders/sia072401.htm.

Pfizer requests that a copy of this news release be included with all distributions of materials relating to TRC Capital Investment’s mini-tender offer related to shares of Pfizer common stock.
