Commenting on the annual results, Daphne Zohar, Founder and Chief Executive Officer of PureTech said:

"I’m very proud of what our team has achieved in 2021. The collaboration and commitment to discovering and developing highly differentiated medicines for devastating diseases where novel treatment options are greatly needed, has resulted in another year full of important accomplishments for PureTech.

"Across our Wholly Owned and Founded Entity programs, we now have 27 therapeutics and therapeutic candidates advancing towards clinical, regulatory and commercial milestones. Twenty of these sit within our Founded Entities where we already have two products that have been cleared for marketing by the United States Food and Drug Administration (the "FDA") and granted marketing authorization in the European Economic Area – Gelesis’ Plenity3 and Akili’s EndeavorRx4. Thirteen of these therapeutic candidates are clinical stage and we look forward to multiple data readouts in the coming year, including data from Karuna’s Phase 3 EMERGENT-2 trial expected in mid-2022 as well data from Vor Bio’s Phase 1/2a clinical trial of VOR33, which is expected in the second half of 2022.

"The other seven therapeutic candidates are being developed within our rapidly advancing and growing Wholly Owned Pipeline, which is curated around our focus on immunological, fibrotic and lymphatic system disorders and builds upon pharmacology that has been validated in humans where our key innovations enable potential unlocking of the broad potential of these therapies. Across our Wholly Owned Programs, we generated significant fundamental value and achieved a number of clinical and business milestones towards our mission of developing transformational medicines for millions of people who have long struggled to find effective treatments. In 2021 alone, we initiated five clinical studies, with four readouts thus far and one that is ongoing.

"Importantly, we are in the fortunate position to be growing our business that is generating non-dilutive capital and we do not currently have to look at public equity markets to raise capital. As such, we have a strong financial position that will allow us to build on the momentum of 2021 and deliver on value driving milestones. In 2021, our consolidated business ended the year with a capital base of $465.7 million, helped by generating non-dilutive cash from the Founded Entities, whilst maintaining significant equity positions, royalty streams and milestones that position us to capture future value. Furthermore, our self-sustaining Founded Entities are set to continue an exciting period of strategic execution, having collectively raised an aggregate of $1.9 billion in recent years, 94% of which came from outside parties.

"Based on the strong foundation we have built to support PureTech’s future growth, our Board and senior leadership team have been considering various approaches to drive additional value for our shareholders, including reviewing a capital allocation strategy that balances investment in the continued growth of our business with potential returns of capital to shareholders. As we evaluate our capital allocation strategy, we intend to engage with shareholders to understand preferences and market perspectives with respect to certain potential near term activities related to the implementation of this strategy.

"We look to the coming months and years with excitement and optimism as we continue to create significant value from innovative science and develop therapeutics that we sincerely believe have the potential to significantly improve treatment outcomes for patients all over the world."

Continued advancement and growth of our Wholly Owned Programs5

Our team, network and insights and expertise in immunology and therapeutic development have enabled the rapid advancement and growth of our Wholly Owned Programs. Focused on immunological, fibrotic and lymphatic system disorders, our Wholly Owned Pipeline builds upon validated biologic pathways and proven pharmacology, and currently consists of seven therapeutic candidates, including LYT-100 (deupirfenidone), a clinical therapeutic candidate that we are pursuing for the potential treatment of a range of conditions involving inflammation and fibrosis and disorders of lymphatic flow, LYT-200, a clinical immuno-oncology fully human monoclonal antibody candidate targeting a foundational immunosuppressive protein, galectin-9, that we are developing for the potential treatment of difficult‑to‑treat solid tumors, LYT-210, a preclinical immuno-oncology therapeutic candidate targeting immunomodulatory gamma delta-1 T cells that we are developing for a range of cancer indications, LYT‑300 (oral allopregnanolone), a clinical therapeutic candidate that we are developing for a range of neurological and neuropsychological conditions, which was generated from our Glyph lymphatic targeting platform, and three therapeutic candidates generated from Alivio, our technology platform that enables targeting of therapeutics locally to the sites of inflammation while minimizing systemic exposure, for the potential treatment of a range of chronic and acute inflammatory disorders: LYT-510 (oral immunosuppressant molecule), in development for the potential treatment of inflammatory bowel disease (IBD) and chronic pouchitis, LYT-500 (oral combination of two therapeutic agents), in development for IBD, and LYT-503/IMB-150, which is being advanced as a partnered program as a potential non-opioid treatment for interstitial cystitis or bladder pain syndrome (IC/BPS). In addition to these programs, we are advancing Orasome and other Technology Platforms for the oral administration of therapeutics. Finally, we are pursuing our meningeal lymphatics research program to develop potential treatments for neurodegenerative and neuroinflammatory diseases. In addition to programs originating from these innovative platforms to fuel our pipeline, we also continually identify external clinical-stage programs that are highly differentiated and complementary to the immuno‑modulation focus of our Wholly Owned Pipeline. Key developments and progress include the following:

Program Highlights

LYT-100

· In the January 2022 post-period, we were pleased to announce results from a randomized, double-blind crossover study in healthy older adults demonstrating that approximately 50% fewer subjects treated with LYT-100 experienced gastrointestinal (GI)-related adverse events (AE) compared to subjects treated with pirfenidone (17.4% vs. 34.0%). Based on these results, additional data generated from our robust LYT-100 clinical program and recent regulatory feedback, we intend to advance LYT-100 into late-stage clinical development for the treatment of idiopathic pulmonary fibrosis (IPF), beginning with a dose-ranging study evaluating six months of treatment with LYT-100 with topline results expected by the end of 2023.

· In 2021, we progressed two Phase 2 clinical trials of LYT-100 including 1) a global, randomized, double-blind, placebo-controlled Phase 2 trial to evaluate the efficacy, safety and tolerability of LYT-100-COV in adults with Long COVID6 respiratory complications and related sequelae and 2) a Phase 2a proof-of-concept study of LYT-100-LYMPH in patients with breast cancer-related, upper limb secondary lymphedema. Topline results from the LYT-100-COV trial are expected in the first half of 2022, and topline results from the LYT-100-LYMPH trial are expected in 2022.

· In 2021, we also initiated a three-month, open-label extension of the LYT-100-COV Phase 2 trial in adults with Long COVID respiratory complications and related sequelae who completed the first portion of the trial. The primary endpoint of the extension trial will measure change in distance walked on the six-minute walk test (6MWT), with secondary endpoints to assess the longer-term safety and tolerability of LYT-100- COV up to 182 days of treatment.

· In 2021, we initiated additional clinical studies to further evaluate the pharmacokinetic (PK), dosing and tolerability of LYT-100 in healthy volunteers and healthy older adults to inform the clinical development of LYT-100 across multiple indications. Results from these studies demonstrated that LYT-100 was well-tolerated at 824mg TID dosing with low rates of GI AEs that were comparable to placebo. These results will further inform our dose-ranging study design in treatment-naïve IPF patients.

· In 2021, we formed a Clinical Advisory Board for IPF and other progressive fibrosing interstitial lung diseases (PF-ILDs). These physicians and researchers with deep expertise in the clinical development of novel therapies in PF-ILDs include Bill Bradford, M.D., Ph.D., biopharma advisor with broad expertise in drug development; Vincent Cottin, M.D., Professor of Respiratory Medicine at Université Claude Bernard Lyon and Coordinator of the National Coordinating Reference Center for Rare Pulmonary Diseases at Louis Pradel Hospital, Hospices Civils de Lyon, Lyon, France; Kevin Flaherty, M.D., Professor at the University of Michigan specializing in IPF and other ILDs; Toby Maher, M.D., Ph.D., Professor of Clinical Medicine and Director of Interstitial Lung Disease at Keck School of Medicine of the University of Southern California; Paul Noble, M.D., Chair of the Department of Medicine at Cedars-Sinai Medical Center and a noted researcher in lung inflammation and fibrosis; and Marlies Wijsenbeek, M.D., Ph.D., pulmonary physician at the Erasmus Medical Center.

· In August 2021, we presented the results of the Phase 1 multiple ascending dose and food effect study of LYT-100 at the virtual European Respiratory Society (ERS) International Congress. The results from the study were subsequently published in the journal Clinical Pharmacology in Drug Development in November 2021.

LYT-200

· In 2021, we progressed the first stage of an adaptive Phase 1/2 clinical trial evaluating LYT-200 (anti-galectin-9 fully human monoclonal antibody) as a single agent for the potential treatment of difficult-to-treat solid tumors. In November 2021, we presented a scientific poster describing the trial at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 36th annual meeting. Topline results from the Phase 1 portion of the study are expected in the first half of 2022. Pending these results, we intend to initiate the Phase 2 expansion cohort portion of the trial, which is designed to evaluate LYT-200 both as a single agent and/or in combination with BeiGene’s tislelizumab, an anti-PD-1 monoclonal antibody, or chemotherapy. The Phase 2 portion of the study is currently planned to enroll patients with a range of solid tumor types, including pancreatic cancer and other GI solid tumors. Under the terms of the clinical trial and supply agreement we entered into with an affiliate of BeiGene, Ltd. in July 2021, we will maintain control of the LYT-200 program, including global R&D and commercial rights, and BeiGene has agreed to supply tislelizumab for use in combination with LYT-200 for the planned Phase 2 study cohorts.

· In November 2021, the FDA granted orphan drug designation to LYT-200 for the treatment of pancreatic cancer. The FDA grants orphan drug designation to novel drug and biologic products for the treatment, diagnosis or prevention of conditions affecting fewer than 200,000 persons in the U.S. Orphan drug designation qualifies PureTech for incentives under the Orphan Drug Act, including tax credits for some clinical trials and eligibility for seven years of market exclusivity in the U.S. if the drug is approved, in addition to our broad intellectual property coverage which can extend the exclusivity into 2038.

LYT-210

· In April 2021, we presented a scientific poster detailing promising preclinical results for LYT-210 (anti-gamma-delta-1 fully human monoclonal antibody) at the 2021 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Virtual Meeting. The research demonstrated that LYT-210 is both highly specific and highly potent, rapidly inducing cell death of immunomodulatory gamma delta-1 cells, while sparing other T cells, such as cytotoxic gamma delta T cells, that play important roles in a healthy immune response.

LYT-300

· In December 2021, we initiated a Phase 1 clinical study of LYT-300 (oral allopregnanolone), the first therapeutic candidate generated from our Glyph platform, for the potential treatment of neurological and neuropsychological conditions. Results from the study are expected in the second half of 2022 and will be used to inform the design of possible future studies evaluating LYT-300 in indications that could include depression, anxiety, sleep disorders, fragile X tremor-associated syndrome, essential tremor and epileptic disorders, among others.

Alivio Technology Platform

· In June 2021, we announced the acquisition of the remaining 22% of outstanding shares in our Founded Entity, Alivio Therapeutics ("Alivio"). Alivio’s therapeutic candidates, in development for inflammatory disorders including IBD, have been integrated into our Wholly Owned Pipeline, and the underlying Alivio technology platform has been added to our lymphatic and inflammation platforms.

· The Alivio technology platform has generated three therapeutic candidates:

− In the 2022 post-period, we nominated a new therapeutic candidate, LYT-510, to our pipeline. LYT-510 is an orally-administered therapeutic candidate for the potential treatment of IBD and chronic pouchitis, which is a rare orphan disease. We intend to file for regulatory approval to initiate first-in-human studies at year end 2022 and initiate a clinical study evaluating LYT-510 as a single agent for the potential treatment of IBD and chronic pouchitis in early 2023.

− LYT-500 is an orally administered combination of therapeutic agents in development for IBD. We expect preclinical proof-of-concept data for LYT-500 in the first half of 2022.

− LYT-503/IMB-150 is a non-opioid pain candidate being developed as a partnered program for the potential treatment of IC/BPS. An Investigational New Drug ("IND") application is expected to be filed for LYT-503/IMB-150 in 2022.

Glyph Technology Platform

· In September 2021, preclinical proof-of-concept research supporting the Glyph technology platform, which showed for the first time that restoring normal function of the mesenteric lymphatics may reverse insulin resistance and modify obesity-associated metabolic disease, was published in Nature Metabolism. Preclinical proof-of-concept work published in the Journal of Controlled Release in February 2021 also supported the platform’s ability to directly target the lymphatic system.

Orasome and Other Technology Platforms for Oral Administration of Therapeutics

· In 2021, we also progressed versatile and programmable oral biotherapeutics approaches, such as our Orasome platform, which is a novel programmable and scalable approach for the oral administration of nucleic acids and other biologics. We established preclinical proof-of-concept supporting the platform’s potential to achieve therapeutic levels of proteins in circulation following the oral administration of therapeutic protein expression systems. We expect to generate additional preclinical data, with Orasomes and other technologies, in 2022.

Meningeal Lymphatics Research Program

· In April 2021, preclinical work supporting our meningeal lymphatics research program was published in Nature. The research suggests that restoring lymphatic flow in the brain, either alone or in combination with passive immunotherapies such as antibodies directed at amyloid beta, has the potential to address a range of neurodegenerative diseases including Alzheimer’s and Parkinson’s diseases and the associated neuroinflammation. The work also uncovered a link between dysfunctional meningeal lymphatics and damaging microglia activation in Alzheimer’s disease, which potentially impairs the efficacy of passive immunotherapies such as amyloid-beta-targeting antibodies. This suggests another route by which restoring healthy drainage patterns could improve clinical outcomes.

Corporate Highlights

· In 2021, we continued to build our clinical development team by bringing together seasoned experts focused on tackling diseases with significant unmet medical needs. Julie Krop, M.D., was appointed as Chief Medical Officer. Dr. Krop oversees all clinical development, regulatory, CMC and medical affairs for advancing our Wholly Owned Pipeline. Other additions to our team included Paul Ford, M.D., Ph.D., SVP of Clinical Development who is primarily overseeing the overall LYT-100 development program, including for IPF.

· In the March 2022 post-period, we appointed Sharon Barber‑Lui to our board of directors as a non‑executive director and as a member of the Audit Committee. She previously led U.S. Oncology Portfolio Strategy, Operations and Business Analytics at Merck & Co. Inc. Ms. Barber-Lui brings extensive experience in finance, operations, portfolio management and commercialization to our board of industry, business, and academic leaders.

· In 2021, we remained deeply committed to making progress in our Environmental, Social and Governance (ESG) program. The second edition of our ESG report has been published as part of the annual report and a new ESG webpage has been launched which can be accessed at investors.puretechhealth.com.

Capital Allocation Strategy

· Based on the strong foundation we have built to support PureTech’s future growth, our Board and senior leadership team have been considering various approaches to drive additional value for our shareholders, including reviewing a capital allocation strategy that balances investment in the continued growth of our business with potential returns of capital to shareholders. Our strategy includes the maintenance of a minimum of three years of cash on hand to fund the continued development and expansion of our Wholly Owned Pipeline and strategic investment in our Founded Entities. Our cash runway is expected into the first quarter of 2025.

· In the future, when appropriate to do so, we will also aim to return a portion of the proceeds we may generate from either (1) the monetization of equity interests in our Founded Entities, (2) the receipt of potential royalty and sublicense income, and/or (3) other sources of proceeds such as strategic partnerships, to shareholders through various mechanisms, including share buybacks or special dividends.

· We may augment this approach should opportunities arise to use available funds for strategic growth opportunities, such as in-licensing of therapeutic candidates or intellectual property, asset purchases, or strategic M&A, to the extent such opportunities are aligned with our long-term strategic vision.

· As we evaluate our capital allocation strategy, we intend to engage with shareholders to understand preferences and market perspectives with respect to certain potential near-term activities related to the implementation of this capital allocation strategy. Any plan to return capital to shareholders will be subject to market and industry conditions at the time, the approval of our Board of Directors, restrictions under the law and other corporate considerations.

Financial Highlights

· In 2021, PureTech sold 1,750,000 shares of Karuna common stock for cash consideration of approximately $218 million in two separate transactions in February and November.

· PureTech Level Cash and Cash Equivalents were $418.9 million as of December 31, 20211. We reiterated our cash runway guidance into the first quarter of 2025.

· Consolidated cash and cash equivalents, which includes cash held at the PureTech level and at Controlled Founded Entities, were $465.7 million as of December 31, 20212.

· PureTech’s Founded Entities raised $731.9 million in 20217 and approximately an additional $105 million in the 2022 post-period, almost all of which came from third parties.

· PureTech Level Cash and Cash Equivalents were $377.9 million, based on consolidated cash and cash equivalents of $413.2 million as of March 31, 20228, with spend largely attributed to the successful progression of Wholly Owned Programs into more advanced stages of development.

PureTech’s Founded Entities matured over the year, with significant clinical and financial momentum9

PureTech’s Founded Entities have made significant progress advancing 20 therapeutics and therapeutic candidates, of which two have been cleared for marketing by the FDA and granted marketing authorization in the European Economic Area and 13 are clinical stage. Key developments included the following:

· Karuna Therapeutics, Inc. (PureTech ownership as of February 15, 2022: 5.6%; We also are eligible to receive payments under our license agreement, including sublicense payments and royalties on net sales)

− In November 2021, Karuna announced further updates to the EMERGENT program’s four ongoing Phase 3 trials, including that topline data from EMERGENT-2, a five-week inpatient trial evaluating the efficacy and safety of KarXT compared to placebo in 246 adults with schizophrenia in the U.S., are expected in mid-2022. EMERGENT-3, a five-week inpatient trial evaluating the efficacy and safety of KarXT compared to placebo in 246 adults with schizophrenia in the U.S. and Ukraine, is underway. EMERGENT-4, a 52-week outpatient, open-label extension trial evaluating the long-term safety and tolerability of KarXT in 350 adults with schizophrenia who completed EMERGENT-2 or EMERGENT-3, and EMERGENT-5, a 52-week outpatient, open-label trial evaluating the long-term safety and tolerability of KarXT in adults with schizophrenia who were not enrolled in EMERGENT-2 or EMERGENT-3, are also underway.

− In 2021, Karuna initiated the Phase 3 ARISE trial evaluating the safety and efficacy of KarXT compared to placebo as an adjunctive treatment in adults with schizophrenia who experience an inadequate response to current standard of care.

− In June 2021, Karuna announced data from its completed Phase 1b trial evaluating the safety and tolerability of KarXT in healthy elderly volunteers, which followed a preliminary analysis of data from the first two cohorts in the trial announced earlier this year. The results suggest that KarXT can be administered to elderly volunteers at doses which achieve xanomeline blood levels similar to those reported in the Phase 2 EMERGENT-1 trial in adults with schizophrenia while maintaining a favorable tolerability profile. Data from the trial also suggest that a lower dose ratio of trospium to xanomeline, compared to the ratios used in Phase 1 trials in healthy adult volunteers and in the Phase 2 EMERGENT-1 trial evaluating KarXT in adults with schizophrenia, was better tolerated by healthy elderly volunteers.

− In November 2021, Karuna announced the evaluation of KarXT for the treatment of dementia-related psychosis (DRP) will initially focus on psychosis in Alzheimer’s disease, the most common subtype of DRP. The initial focus on the Alzheimer’s disease dementia subtype reflects various strategic development, regulatory and commercial considerations, and Karuna remains interested in exploring KarXT in other dementia subtypes in future development programs. Karuna plans to initiate a Phase 3 program in mid-2022.

− In late 2021, Karuna initiated a Phase 1 trial of an advanced formulation of KarXT as it continued to advance its earlier pipeline of muscarinic receptor targeted programs and novel formulations of KarXT. Karuna is also advancing its artificial intelligence-based target agnostic discovery program for treating psychiatric and neurological conditions.

− In November 2021, Karuna announced its entry into an exclusive license agreement with Zai Lab (Shanghai) Co., Ltd. (Zai) for the development, manufacturing and commercialization of KarXT in Greater China, including mainland China, Hong Kong, Macau and Taiwan. Under the terms of the agreement, Karuna received a $35.0 million upfront payment and is eligible to receive certain development and regulatory milestone and sales milestone payments, as well as royalties based on annual net sales of KarXT in Greater China.

− In February 2021, Karuna announced that results from the EMERGENT-1 Phase 2 clinical trial evaluating KarXT for the treatment of schizophrenia were published in the New England Journal of Medicine (NEJM).

− In March 2021, Karuna completed a follow-on public offering of its common stock, from which it received net proceeds of $270.0 million.

− In 2021, PureTech sold 1,750,000 shares of Karuna common stock for cash consideration of approximately $218 million in two separate transactions in February and November.

· Akili Interactive Labs, Inc. (PureTech ownership as of December 31, 2021: 22.3%)

− In the January 2022 post-period, Akili entered into a definitive agreement to become publicly traded via a merger with Social Capital Suvretta Holdings Corp. I ("SCS") (Nasdaq: DNAA), a special purpose acquisition company. The transaction is expected to close in mid-2022, after which Akili will be listed on the Nasdaq stock market under the new ticker symbol "AKLI". The transaction implies a post-money equity value of the combined company of up to approximately $1 billion and is expected to deliver up to $412 million in gross cash proceeds to Akili, including the contribution of up to $250 million of cash held in SCS’s trust account and $162 million from PIPE investors at $10 per share.

− In May 2021, Akili announced the closing of a $160 million combined equity and debt financing. With the completion of the oversubscribed Series D financing, the funding is expected to accelerate commercialization of EndeavorRx4, enable expansion of core technologies to treat acute and chronic cognitive disorders and drive further research and development of potential new digital therapeutics.

− In March 2021, the full data from a multi-site open-label study (the STARS Adjunct study) evaluating the impact of EndeavorRx (AKL-T01) on symptoms and functional impairments in children with attention-deficit/hyperactivity disorder (ADHD) was published in Nature Digital Medicine. Statistically significant improvement was demonstrated in all predetermined endpoints of the study, which included parent and clinician ratings of children’s ADHD symptoms and related impairments in daily life.

− In the February 2022 post-period, Akili announced the publication of full data in the medical journal PLOS ONE from a single arm, unblinded study conducted by Dr. Elysa Marco at Cortica Healthcare and Drs. Joaquin Anguera and Courtney Gallen at the University of California, San Francisco. The study measured electroencephalography (EEG) data alongside behavioral and clinical metrics of attention in children with ADHD using AKL-T01 (EndeavorRx). Data from the study show that EndeavorRx treatment resulted in increased brain activity related to attention function, as measured by EEG, which correlated with improvements in objective behavioral measures of attention.

− In September 2021, Akili announced topline results of a Phase 2 study of SDT-001 (Japanese version of AKL-T01), a digital therapeutic designed to improve measures of attention in children diagnosed with attention-deficit/hyperactivity disorder (ADHD). The study, conducted by Akili partner Shionogi & Co., Ltd., was designed to evaluate the feasibility, safety and efficacy of the digital therapeutic in children with ADHD and to inform the design of a potential pivotal study. Results showed the treatment was well-received by patients and demonstrated improvements in ADHD inattention symptoms consistent with those seen across previous studies of AKL-T01.

− In the March 2022 post-period, Akili announced it had been named to Fast Company’s prestigious list of the World’s Most Innovative Companies for 2022. This list honors businesses that are making the biggest impacts on their industries and culture as a whole and thriving in today’s ever-changing world.

− In July 2021, Akili introduced new gaming features and functionalities to its EndeavorRx treatment. Akili is releasing these new gameplay features as it expands its pre-launch activities to bring EndeavorRx to families and healthcare professionals.

− In April 2021, Akili announced collaborations with Weill Cornell Medicine, New York-Presbyterian Hospital and Vanderbilt University Medical Center to evaluate Akili digital therapeutic AKL-T01 as a treatment for patients with cognitive dysfunction following COVID-19 (also known as "COVID fog"). Under each collaboration, Akili will work with research teams at each institution to conduct two separate randomized, controlled clinical studies evaluating AKL-T01’s ability to target and improve cognitive functioning in COVID-19 survivors who have exhibited a deficit in cognition. Akili expects data from the studies in COVID fog in the second half of 2022.

− In August 2021, Akili and Australian digital health company TALi (ASX:TD1), completed an agreement for Akili to license TALi’s technology designed to address early childhood attention impairments. The companies plan to work together to execute clinical trials of the TALi technology in pediatric ADHD in the U.S. and pursue FDA regulatory clearance. Under the terms of the agreement, Akili will lead potential U.S. commercialization and roll-out.

− In the March 2022 post-period, Akili appointed Jon David as Chief Product Officer. A 20-year veteran of the games industry, Mr. David joins Akili to develop and execute the strategic vision of Akili’s future product pipeline after serving as Vice President and General Manager at Glu Mobile, acquired in 2021 by Electronic Arts, where he led the development of both new IP and hit franchises including Covet Fashion and Diner Dash Adventures. Mr. David also guided the success of fan-favorite franchises and the launches of hit titles including Plants vs. Zombies 2 and Plants vs. Zombies Garden Warfare.

· Gelesis Holdings, Inc. (PureTech ownership as of March 31, 2022: 23.5%; We also are eligible to receive payments under our license agreement, including sublicense payments and royalties on net sales)

− In December 2021, Gelesis announced that Plenity is now broadly available across the U.S. to adults who meet the prescription criteria.

− In the January 2022 post-period, Gelesis announced the completion of its business combination with Capstar Special Purpose Acquisition Corp. (NYSE: CPSR) ("Capstar"). Gelesis Holdings, Inc. began trading on the New York Stock Exchange under the ticker symbol "GLS" on January 14, 2022.

− In January 2022 post-period, Gelesis launched the "Who Said?" marketing campaign across the U.S., which challenges many long-held cultural and societal assumptions around weight loss. Plenity’s multichannel campaign encompasses TV, digital, social and Out of Home (OOH) to grow awareness of Plenity’s novel approach to weight management.

− In the March 2022 post-period, Gelesis announced preliminary results from its broad awareness media campaign, noting that within the first three weeks, the company saw a 3-fold increase in web traffic and 3.5-fold increase in the number of individuals seeking a new prescription compared to previous months when supply was limited.

− In November 2021, Gelesis’ first commercial-scale manufacturing line was completed and validated, and the company announced that it had received a $30 million fully paid pre-order, in addition to the $10 million pre-order received in January 2021, for its first commercial product for weight management, Plenity, from Ro, a leading U.S. direct-to-patient healthcare company.

− In late 2021, both primary endpoints were achieved in the Gelesis LIGHT-UP study of GS200 in adults with overweight or obesity who also have prediabetes or type 2 diabetes.

− In November 2021, Gelesis announced a publication in Nature’s Scientific Reports describing the genesis of the underlying technology and engineering process for Gelesis’ non-systemic superabsorbent hydrogels. These new materials were designed to replicate compositional and mechanical properties of raw vegetables, and the paper describes their therapeutic approach for weight management as well as possible future solutions for other gut-related conditions.

− In May 2021, Gelesis presented a scientific poster at the American Association of Clinical Endocrinology (AACE) 2021 Annual Virtual Meeting. The post-hoc analysis showed that treatment for weight management with Plenity decreased a marker for liver fibrosis (the NAFLD fibrosis score) compared to placebo.

− In the January 2022 post-period, Gelesis appointed Inogen Co-Founder and former CFO, Ali Bauerlein, to its Board of Directors and Audit Committee. Ms. Bauerlein brings success in scaling to $300M+ revenue in a direct-to-consumer business model and public company execution as Gelesis plans to scale Plenity to meet growing consumer demand.

· Vor Bio Inc. (PureTech ownership as of March 4, 2022: 8.6%)

− In February 2021, Vor Bio announced the pricing of its initial public offering of common stock on the Nasdaq Global Market under the symbol "VOR". The aggregate gross proceeds to Vor Bio from the offering were approximately $203.4 million, before deducting the underwriting discounts and commissions and other offering expenses payable by Vor Bio.

− In the March 2022 post-period, Vor Bio announced VCAR33 is now made up of two programs with different cell sources. The VCAR33 programs are chimeric antigen receptor T (CAR-T) cell therapy candidates designed to target CD33, a clinically-validated target for AML. VCAR33AUTO uses autologous cells from each patient, and is being studied in an ongoing Phase 1/2 clinical trial sponsored by the National Marrow Donor Program (NMDP) in young adult and pediatric patients with relapsed/refractory AML in a bridge-to-transplant study. VCAR33ALLO uses allogeneic healthy donor-derived cells. Vor Bio also announced it plans to collect initial data on VOR33 from the VBP101 clinical trial and initial clinical data from the VCAR33ALLO program prior to IND submission for the Treatment System following ongoing discussions with the FDA and alongside improved scientific understanding of the differences in T-cell sources.

− In September 2021, the FDA granted Fast Track designation to VOR33, Vor Bio’s lead engineered hematopoietic stem cell (eHSC) therapeutic candidate for the treatment of acute myeloid leukemia (AML).

− Vor Bio initiated VBP101, a Phase 1/2a clinical trial of VOR33 for AML patients who currently have limited treatment options and expects to report VOR33’s initial clinical data in the first half of 2022.

− In November 2021, Vor Bio announced its first multi-targeted treatment system comprising VOR33-CLL1 multiplex-edited eHSC therapy and VCAR33-CLL1 multi-specific CAR-T therapy. Vor Bio continues to make progress on editing multiple antigens with its eHSC platform.

− In June 2021, Vor Bio announced the build-out of an in-house clinical manufacturing facility in Cambridge, Massachusetts in the same premises as Vor Bio’s current headquarters, to support flexible manufacturing for the company’s eHSC and CAR-T product candidate pipeline for patients with blood cancers. Vor Bio anticipates that the facility will be operational in 2022.

− In July 2021, Vor Bio announced the formation of a collaboration with Janssen Biotech, Inc. (Janssen), one of the Janssen Pharmaceutical Companies of Johnson & Johnson. The agreement was facilitated by Johnson & Johnson Innovation. Under the terms of the collaboration, Vor Bio will investigate the combination of these two technologies into a treatment solution, pairing Vor Bio’s "invisible" eHSC transplant platform with one of Janssen’s bi-specific antibodies in development for AML. The collaboration agreement provides that each company retains all rights and ownership to their respective programs and platforms.

− In June 2021, Vor Bio entered into a multi-year strategic collaboration and license agreement with Abound Bio to research both single- and multi-targeted CAR-T treatments to be used in combination with Vor Bio’s eHSC platform, with the goal of generating novel treatment systems for patients fighting AML and other devastating forms of blood cancer.

− In January 2021, Vor Bio announced that the FDA had accepted the company’s IND application for VOR33. In May 2021, Vor Bio announced that it received the Canadian clinical trial application clearance for VOR33 from Health Canada.

− In June 2021, Vor Bio announced the appointment of Matthew R. Patterson as Chairman of its Board of Directors. Mr. Patterson brings nearly 30 years of senior leadership experience in the research, development and commercialization of innovative therapeutics, most recently at Audentes Therapeutics, Inc., which he co-founded and led as the company’s Chief Executive Officer from its inception in 2012 through its acquisition by Astellas Pharma Inc. in January 2020.

· Vedanta Biosciences, Inc. (PureTech ownership as of December 31, 2021: 41.4%)

− In October 2021, Vedanta announced that its Phase 2 clinical trial of VE303, an orally administered investigational live biotherapeutic product (LBP) in development for the prevention of recurrent C. difficile infection (CDI) in high-risk patients, met its primary endpoint of preventing disease recurrence through Week 8. VE303 achieved a 31.7% absolute risk reduction in rate of recurrence when compared with placebo, representing a greater than 80% reduction in the odds of a recurrence. This is believed to be the most advanced clinical trial of an investigational drug based on a rationally defined bacterial consortium, a microbiome-based therapeutic approach that delivers orally administered candidates of precisely known composition that can be manufactured with pharmaceutical-grade consistency. Based on the Phase 2 data, the Biomedical Advanced Research and Development Authority (BARDA) exercised its first contract option for additional funding of $23.8 million, pursuant to its existing 2020 contract with Vedanta, to support a planned Phase 3 clinical trial of VE303.

− In January 2021, Vedanta announced a $25 million investment from Pfizer, as part of the Pfizer Breakthrough Growth Initiative. Vedanta will retain control of all of its programs and has granted Pfizer a right of first negotiation on VE202, Vedanta’s 16-strain defined bacterial consortium candidate. As part of the investment, Michael Vincent, M.D., Ph.D., Senior Vice President and Chief Scientific Officer, Inflammation & Immunology Research Unit at Pfizer, joined Vedanta’s Scientific Advisory Board.

− In late 2021, Vedanta also completed the build-out of its Phase 3 and commercial launch CGMP manufacturing facility for supply of VE303.

− In June 2021, Vedanta presented additional results from a Phase 1 study in healthy volunteers of VE202, Vedanta’s 16-strain defined bacterial consortium candidate for IBD, at the International Human Microbiome Consortium Congress 2021 (IHMC). The data summarized the long-term safety and colonization dynamics of the 16-strain version of VE202 in 31 healthy volunteers. Vedanta plans to initiate a Phase 2 clinical trial of VE202 in mild to moderate ulcerative colitis patients.

− In 2021, Vedanta’s ongoing Phase 1/2 clinical trial of VE416 for food allergy continued to progress.

− In July 2021, Vedanta announced results from the Phase 1 study evaluating the safety and initial clinical activity of VE800, an immuno-oncology therapeutic candidate, in combination with Bristol Myers Squibb’s Opdivo (nivolumab) in 54 patients across select types of advanced or metastatic cancers. VE800 demonstrated an acceptable safety and tolerability profile, though the observed response rates did not meet the prespecified criteria to advance into the next stage of the study. Vedanta is analyzing blood, stool and tumor samples from patients in whom response or disease control was observed in order to profile patient subtypes that might benefit from microbiome manipulation. Vedanta plans to present the results at a future medical conference and will continue work to identify cancer settings and patient populations that might benefit from microbiome manipulation with its defined bacterial consortia.

− In July 2021, Vedanta closed a $68 million financing, which included the $25 million investment from Pfizer as part of the Pfizer Breakthrough Growth Initiative announced in January 2021. Vedanta plans to use the proceeds to advance its pipeline of defined bacterial consortia, including progressing VE303 into a Phase 3 clinical trial in patients at high risk for recurrent CDI, initiating a Phase 2 clinical trial of VE202 in mild to moderate ulcerative colitis and continuing to advance programs in additional indications.

− In February 2021, Vedanta appointed Mark Mullikin as Chief Financial Officer. Mr. Mullikin brings 25 years of experience raising and deploying capital for life sciences companies, and most recently held leadership roles in finance and investor relations at publicly-traded companies such as Editas Medicine and Novartis.

− In October 2021, Vedanta announced the appointment of Simona Levi, Ph.D., J.D., as Chief Legal Officer and Corporate Secretary. Dr. Levi brings over 25 years of U.S. and international legal experience with private and public companies across the life sciences industry focusing on complex transactions, intellectual property law and litigation as well as corporate governance.

PureTech’s 2021 Annual General Meeting (AGM) will be held on June 15, 2022 at 11:00am EDT / 4:00pm BST at PureTech’s headquarters, which is located at 6 Tide Street, Boston, Massachusetts, United States. Please note that in order to protect the health and wellbeing of our people and our shareholders we continue to monitor developments relating to COVID-19 and, in light of increased circulation of new variants in different regions and potentially disruptive travel limitations, the Company has decided to hold the AGM in the United States where most of the Directors are resident.

While the Company’s preference had been to welcome shareholders in person to the 2022 AGM in the United Kingdom, we considered the conditions at hand and are proposing to hold the AGM at our Boston office in the United States. Shareholders are strongly encouraged to submit a proxy vote in advance of the meeting and to appoint the Chair of the meeting to act as their proxy. If a shareholder wishes to attend the meeting person, we ask that the shareholder notify the Company by email to [email protected] to assist us in planning and implementing arrangements for this year’s AGM. The health and welfare of the Company’s shareholders, as well as its employees and partners, is the number one priority.

The Company appreciates that a number of its shareholders are not resident or located in the United States and asks shareholders to participate in the AGM by submitting any questions in advance and voting via proxy rather than attending in person. As such, any specific questions on the business of the AGM and resolutions can be submitted ahead of meeting by e-mail to [email protected] (marked for the attention of Dr. Bharatt Chowrira).

Shareholders are encouraged to complete and return their votes by proxy, and to do so no later than 4:00 pm (BST) on June 13, 2022. This will appoint the chair of the meeting as proxy and will ensure that votes will be counted even though attendance at the meeting is restricted and you are unable to attend in person. Details of how to appoint a proxy are set out in the notice of AGM.

PureTech will keep shareholders updated of any changes it may decide to make to the current plans for the AGM. Please visit the Company’s website at www.puretechhealth.com for the most up to date information.
