Pfizer Responds to Delaware Chancery Court Ruling Pfizer Inc. issued the following statement in response to the Delaware Chancery Court’s decision denying Pfizer’s request for a temporary restraining order to prevent Metsera Inc. from terminating the existing merger agreement in favor of a competing proposal from Novo Nordisk. “The company remain confident in the merits of claims and belief that Metsera has acted in breach of its contractual obligations and that Metsera’s directors have breached their obligations to act in the best interest of Metsera’s shareholders. Today’s decision does not address the merits of the underlying legal issues raised, and Pfizer intends to continue to pursue its claims vigorously through the ongoing litigation process as well as in its parallel antitrust litigation pending in Delaware federal court. The company is confident that Novo Nordisk’s unprecedented and illegal scheme to circumvent antitrust scrutiny will not stand. Novo Nordisk’s proposal is illusory and cannot constitute a superior proposal under the terms of merger agreement with Metsera. The company believes that antitrust regulators in the U.S. and elsewhere around the world will not tolerate Novo Nordisk’s flagrant attempt to make an end run around the antitrust laws and potentially gain the ability to quash an emerging competitor. The FTC’s letter to both Metsera and Novo Nordisk undermines their assertions that their transaction structure is legal and faces little risk, citing precedent cases with similar structures that were deemed illegal under the HSR Act and could constitute illegal gun jumping. Importantly, the FTC has warned Metsera and Novo Nordisk that proceeding with the transaction could result in the unwinding of the transaction, including a refund of any money paid to Metsera, liability to the companies and their directors, as well as daily civil penalties. In parallel, Pfizer will take action to preserve its rights under its previously-signed agreement, which believe offers the best path forward for Metsera’s shareholders by offering certain near-term value as well as value for consumers and patients around the world by ensuring that Metsera’s promising programs are in the hands of a company with the resources, capabilities and incentives to compete vigorously in the market for obesity medications.

Pfizer Inc. Files Federal Antitrust Claims in Second Lawsuit Against Metsera, its Controlling Stockholders and Novo Nordisk A/S Pfizer Inc. announced that it has filed a second lawsuit against Metsera, Inc., its controlling stockholders, and Novo Nordisk A/S in the United States District Court for the District of Delaware. The lawsuit asserting that Novo Nordisk's recent proposal to acquire Metsera constitutes an anticompetitive action by Novo Nordisk to protect its dominant market position in GLP-1s by capturing and killing a nascent American competitor before it gains the support of Pfizer, one of America's leading pharmaceutical companies. The lawsuit claims that Novo Nordisk's proposed transaction violates Section 7 of the Clayton Act because of the anticompetitive effects it would have in the GLP-1 drug markets to the detriment of millions of Americans who suffer from obesity, diabetes, and other metabolic conditions, that it constitutes an anticompetitive conspiracy between Novo Nordisk and Metsera in restraint of trade in violation of Section 1 of the Sherman Act, and that it constitutes attempted monopolization and conspiracy to monopolize under Section 2 of the Sherman Act. The litigation further alleges that Metsera's controlling stockholders, Validae Health, L.P., Population Health Partners GP, LLC, ARCH Venture Fund XII, L.P., and ARCH Venture Fund X.P., and ARCH venture Fund X.P. have conspired with Metsera and Novo Nordisk in furtherance of these anticompetitive activities. Pfizer intends to seek all appropriate remedies, including injunctive relief to ensure that Novo Nordisk's anticompetitive proposed transaction is not permitted to move forward. Pfizer said it "is taking this action to preserve and enhance competition in this important therapeutic area and to stop Novo Nordisk from illegal paying off Metsera and its controlling stockholders to gain control of, and impair and potentially kill, an emerging U.S. competitor. Metsera's and its controlling stockholders' actions, as well as those of Novo Nordisk, are in clear violation of the antitrust laws." As previously announced, Pfizer has also filed a separate lawsuit against Metsera, its Board of Directors and Novo Nordisk in the Delaware Court of Chancery and a motion for a temporary blocking order to block Metsera from terminating the merger agreement.

Pfizer Inc. Files Lawsuit Against Metsera, Inc. and Novo Nordisk, S.A. for Breach of Merger Agreement Pfizer Inc. announced that it has filed a lawsuit against Metsera, Inc., its Board of Directors, and Novo Nordisk, S.A. in the Delaware Court of Chancery. The lawsuit asserting claims for breach of contract, breach of fiduciary duty, and tortious interference in contract arising from Metsera's breach of its obligations under the merger agreement between Pfizer and Metsera. Pfizer alleges that the Novo Nordisk offer cannot qualify as a "Superior Company Proposal" under the terms of the merger agreement, including because, relative to the Pfizer deal, the Novo Nordisk transaction is not reasonably likely to be completed on the terms proposed in light of the significant regulatory risk of the proposal. By contrast, the U.S. Federal Trade Commission granted early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, with respect to Pfizer's pending acquisition of Metsera. All regulatory approvals in respect of Pfizer's acquisition of Metsera have been obtained, and Pfizer is ready to complete the transaction shortly following the Metsera stockholder meeting on November 13. As set out in the lawsuit, the proposed Novo Nordisk transaction is an illegal attempt by a company with a dominant market position to suppress competition and uses an unprecedented structure designed to deliberately evolve antitrust review. Metsera's Board previously determined that Novo Nordisk's prior proposal with an identical structure posed unacceptable regulatory risks, and these risks have not changed. The lawsuit also Alleges that the proposed special dividend contemplated by Novo Nordisk's proposal is a violation of Delaware law and that the Metsera Directors have breached their fiduciary duties by, among other things, securing a self-interested indemnification provision from Novo Nordisk designed to cover their unlawful conduct. Pfizer has filed a motion with the Court of Chancery requesting that it issue a temporary restraining order to block Metsera from terminating the merger agreement to allow Pfizer time to be heard on this important matter. Pfizer said it " is taking this action to enforce and preserve its rights under the merger agreement. Metsera's and its Directors' actions, as well as those of Novo Nordisk, are in clear violation of their respective contractual and legal obligations. Pfizer seeks all appropriate remedies, including injunctive relief and damages, to address the harm caused by Metsera's and Novo Nordisk's conduct and to ensure that the terms of the merger agreement are fully enforced.

Metsera Reports Positive Phase 2B Results for First- and Best-In-Class Ultra-Long Acting GLP-1 RA Candidate MET-097I, Enabling Rapid Transition into Phase 3 Metsera, Inc. announced positive topline data from VESPER-1 and positive data from a planned interim analysis for tolerability of VESPER-3 – two Phase 2b trials of MET-097i, a first-in-class fully biased, ultra-long acting GLP-1 receptor agonist (RA) with potential for monthly dosing. In VESPER-1, MET-097i demonstrated mean placebo-subtracted weight loss of up to 14.1% after 28 weekly doses. MET-097i demonstrated potentially class-leading tolerability in both trials. At the highest evaluated dose in VESPER-3, there was minimal diarrhea signal and a risk difference from placebo of 13% nausea and 11% vomiting at 12 weeks after two titration steps. The randomized, placebo-controlled, double-blind VESPER-1 and VESPER-3 Phase 2b trials include populations with overweight or obesity without type 2 diabetes. In VESPER-1, MET-097i was evaluated in 239 participants with doses ranging from 0.4 mg to 1.2 mg, administered once weekly over 28 weeks without titration, with an ongoing study extension that includes less frequent dosing options. VESPER-3 is an ongoing trial with 268 subjects enrolled, designed to evaluate the efficacy and tolerability of multiple monthly doses of MET-097i for 28 weeks. It includes a pre-specified interim analysis after 12 weekly doses to assess the tolerability of various dose escalation strategies. The study populations are representative of a typical Phase 3 chronic weight management trial, with an approximate BMI in both studies of 36 and approximately two thirds female participants. Topline results from these Phase 2b trials include: Body weight loss up to 14.1% in VESPER-1. Body weight loss in VESPER-1 was dose-dependent, ranging up to a placebo-subtracted mean of 14.1% at 28 weeks at the 1.2 mg dose level, with individual responses as high as 26.5%. An exploratory analysis at the end of the weekly dosing phase of the study extension of VESPER-1 at 36 weeks demonstrated substantial continued weight loss, highlighting that no plateau had been reached. An exploratory analysis at the end of the weekly dosing phase of the study extension of VESPER-1 at 36 weeks demonstrated substantial continued weight loss, highlighting that no plateau had been reached. As VESPER-3 is ongoing, weight loss is not reported. Class-leading tolerability results. MET-097i demonstrated placebo-like tolerability at a starting dose of 0.4 mg across multiple arms in both trials, and the potential for class-leading tolerability with one- or two-step titration. In the VESPER-3 trial arm that titrated from 0.4 mg to 0.8 mg to 1.2 mg over 12 weeks, there was minimal diarrhea signal, a 13% risk difference from placebo for nausea, and 11% for vomiting. High participant retention. VESPER-1 had 2.9% total study discontinuation, with only two of 239 participants discontinuing treatment due to adverse events. VESPER-3 is ongoing, with high participant retention to date. Phase 3 dosing confirmed. Clear dose-response on weight loss in VESPER-1 and incremental benefit on tolerability of one- or two-step titration in VESPER-3 enabled Metsera to select final Phase 3 dosing regimens for titration and maintenance, and confirm MET-097i as the most scalable nutrient-stimulated hormone (NuSH) analog in development, with equivalent weight loss to market leaders at a 5- to 10-fold lower dose and substantially fewer titration steps. Dose and exposure-response models informed by these trial results give Metsera a high degree of confidence that doses of MET-097i could match or exceed the performance of tirzepatide 15 mg at steady state.
