Grove-Laugesen et al., Thyroid (2023): Completer rates for combined arms: ATD remission 56.0%, continuing ATD 18.8%, ATD relapse of 21.8%, ablation of 3.4%. Of the 58K 1st line ATD patients, a total of ~75% are either in remission (56.0%: 32.5K) or continued ATDs (18.8%: 10.9K) 3. Azizi et al., Thyroid (2019): ATD remission for patients on long-term ATDs is 85%. Of the 10.9K patients who continued ATDs, 15% relapse (1.6K) and 85% go into remission (9.3K). These 9.3K patients in remission will have a 15% rate of relapse resulting in 1.4K relapses. From the original 10.9K patients who continued on ATDs, there will be a total of 3K (1.4K +1.6K) relapses, 4. Stokland et al., J Clin Endocrinol Metab. (2023): Relapse post remission 15%. Of the 42K patients who are in remission, 15% will relapse (6.3K). In total, the late relapses from remission and continued ATDs will be ~9.3K, resulting in a weighted average relapse rate of ~19% (6.3K relapses from the 32.5K patients in remission averaged with the 3K relapses from the 10.5K patients who continued on ATDs). 5.Roivant Claims Analysis – 2022 prevalent patient population based on a two-year lookback for diagnosis.

Q&A

145 Genevant & Arbutus LNP Litigation Lindsay Androski Special Counsel, Genevant CEO, Arbutus Matt Gline CEO, Roivant

146 We believe that both the Moderna COVID-19 vaccine (SPIKEVAX) and Pfizer/BioNTech’s COVID-19 vaccine (COMIRNATY) infringe multiple Genevant/Arbutus LNP patents In the ex-US Moderna litigation, initial court hearings and rulings are expected in 2026 Markman rulings (claim construction) have been issued in both US cases – viewed by Genevant generally to be favorable Global COVID-19 vaccine sales since launch have been ~$145BN between Moderna and Pfizer/BioNTech In the US Moderna litigation, a jury trial has been scheduled for March 2026. Awaiting court scheduling in the Pfizer/BioNTech litigation Key Takeaways: LNP Litigation For investor audiences only Note: All references are to calendar years and are approximate and subject to change. The timing of the litigation-related events noted above is subject to change, including at the discretion of the court. See Slide 2 for further information on these forward-looking statements

Genevant and Arbutus Corporate History 2006 Protiva acquired Tekmira, another company working on LNP technology Roivant set out to assemble a leading global HBV company by merging OnCore Biopharma with Protiva/Tekmira to form Arbutus Biopharma Roivant and Arbutus launched Genevant as a joint venture to focus on Arbutus’ LNP and ligand conjugate delivery technologies, with Arbutus’ focus remaining on HBV therapeutics 2008 2015 2018 Protiva and Alnylam (an RNAi developer) published a landmark study in Nature demonstrating the first effective gene silencing in monkeys, using Protiva’s LNP technology 2000 Ian MacLachlan co-founded Protiva, which became a pioneer in LNP technology 147

148 A Leading Nucleic Acid Delivery Company Industry-leading LNP delivery capabilities and IP portfolio Selective collaboration business model, partnering with payload companies to develop innovative nucleic acid medicines The first LNP technology to be part of an FDA-approved RNA product, Alnylam’s Onpattro® developed under LNP license from Arbutus

Some of the US patents licensed by Genevant from Arbutus include: Moderna previously sought to invalidate two of the particle composition patents referenced above with IPR challenges but was largely unsuccessful Litigation is ongoing against Moderna in the US and certain other jurisdictions and against Pfizer/BioNTech in the US to seek appropriate compensation for the unauthorized use of Genevant’s/Arbutus’s patented technology 149 Genevant/Arbutus IP Portfolio and Pending Litigation Subject Matter US Patent No. Expiration Date Particle Composition 8,058,069 April 2029 8,492,359 April 2029 8,822,668 April 2029 9,364,435 April 2029 11,141,378 April 2029 mRNA-LNP Compositions 9,504,651 July 2023 Manufacturing Methods 11,298,320 June 2023 11,318,098 June 2023

150 mRNA COVID-19 Vaccines from Moderna and Pfizer/BioNTech Have Generated Over $145BN in Revenue Revenue as of 9/30/2025 Data and sales calculated from Evaluate and company docs from MRNA, PFE, and BNTX Total SpikeVax Sales account for ~1/3 of mRNA vaccine sales to date; Comirnaty sales account for remaining ~2/3 US SpikeVax Sales make up ~10% of global COVID-mRNA vaccine sales to date Genevant/ABUS continue to pursue recovery against Pfizer and BioNTech in the US, as well as against Moderna in the US and in several other major markets

Moderna Case

152 In February 2022, Genevant and Arbutus Jointly Filed a Complaint Against Moderna Asserting Patent Infringement on Patents Related to LNP Technology Case filed in the US District Court for the District of Delaware asserting infringement of six patents Genevant and Arbutus did not seek an injunction or otherwise to impede the sale, manufacture, or distribution of Moderna’s COVID-19 vaccine, given the unprecedented global emergency We recognize the important work of Moderna that helped lead to a lifesaving vaccine in record time That success was built on, and made possible by, the substantial advances and contributions of Arbutus and Genevant scientists, which Moderna utilized extensively well before COVID-19 The filing of this lawsuit was necessary because Moderna did not pursue and obtain a license to Genevant’s LNP technology for COVID-19

153 Moderna Patent Litigation Timeline: Years in the Making Note: All references are to calendar years and are approximate and subject to change. The timing of the litigation-related events noted above is subject to change, including at the discretion of the court. See Slide 2 for further information on these forward-looking statements Early 2023 The U.S. DOJ filed a Statement of Interest in support of MRNA; Court reaffirmed Nov 2022 decision Feb 2022 Genevant and Arbutus jointly filed a complaint against MRNA 2025 Initiated international proceedings against MRNA; discovery and summary judgment briefing concluded in US. Jan 2026 Pretrial submissions due Early 2024 Court issued a Markman ruling construing disputed patent terms Nov 2022 Court denied MRNA’s partial motion to dismiss based on Section 1498 (which would shift liability to U.S. taxpayers) March 2026 Jury trial scheduled (~2 weeks) 2026 First international hearings in ex-US cases

154 Summary Judgment Motions Filed in US Moderna Case Note: All references are to calendar years and are approximate and subject to change. The timing of the litigation-related events noted above is subject to change, including at the discretion of the court. See Slide 2 for further information on these forward-looking statements Genevant and Arbutus Filed 5 Motions for Summary Judgment Moderna cannot relitigate obviousness arguments against the Lipid Composition Patents (the ’359, ’435, and ’378 patents) already raised in its unsuccessful IPRs and appeals. Moderna cannot argue at trial that the Asserted Patents are invalid because they do not enable someone in the art to practice the inventions without undue experimentation. Arbutus and Genevant did not derive the invention disclosed in the ’651 patent from a much later Moderna invention. 28 U.S.C. § 1498 does not apply (cross motion). Moderna’s indefiniteness arguments fail as a matter of law (cross motion). Moderna Filed 3 Motions for Summary Judgment 28 U.S.C. § 1498 requires Arbutus and Genevant to recover damages for infringement under one government contract from the U.S. government, not Moderna. Plaintiffs’ claims under the doctrine of equivalents are barred by amendments and arguments made to the PTO during patent prosecution, and Arbutus and Genevant should be able to recover for literal infringement only. The asserted claims of the ’651 patent are invalid for indefiniteness with respect to the Court’s construction of the term “fully encapsulated.” Patents Remaining to Be Litigated at Trial (Following Judge’s Order on Claim Narrowing) Subject Matter US Patent No. Particle Composition 8,492,359 9,364,435 11,141,378 mRNA-LNP Compositions 9,504,651

155 Moderna’s Motions to Exclude Genevant/Arbutus’ Expert Testimony Damages methodologies Opinions regarding willful infringement Fractionation testing Opinions regarding infringement Opinions regarding applicability of Section 1498 Genevant/Arbutus’ Motions to Exclude Moderna’s Expert Testimony Damages methodologies Certain opinions regarding Infringement, Doctrine of Equivalents, Written Description and Enablement Opinions regarding obviousness Daubert Motions: Judge to Decide Admissibility of Certain Expert Testimony

Key Upcoming Milestones in US Litigation Judge to rule on summary judgment motions, including decision on § 1498, before the jury trial in March Judge will rule on Daubert motions, which could narrow the expert testimony allowed to be presented on both sides or impact presentations on damages, infringement, willful infringement, and invalidity A jury trial is currently scheduled to start on March 9, 2026, in the U.S. District Court of Delaware. Jury selection will occur that day Genevant and Arbutus first, and Moderna second, will present their cases over the course of ~2 weeks Jury will deliberate, and parties will remain in Delaware until the jury issues their verdict Jury Trial Summary Judgement/Daubert Motions Any jury verdict is expected to be appealed Post-trial motions entertained by trial court in period after trial An appeal could take an additional 18-24 months If the jury rules favorably for Genevant/Arbutus, to obtain a stay of execution of judgment pending appeal, Moderna would likely need to obtain a bond or post cash collateral with the court within 30 days After the Trial 156 Note: All references are to calendar years and are approximate and subject to change.
