Note: This figure represents the stage of development for each Founded Entity’s most advanced therapeutic candidate. While PureTech maintains ownership of equity interests in its Founded Entities, the Company does not, in all cases, maintain control over these entities (by virtue of (i) majority voting control and (ii) the right to elect representation to the entities’ board of directors) or direct the management and development efforts for these entities. Consequently, not all such entities are consolidated in the financial statements. Where PureTech maintains control, the entity is referred to as a Controlled Founded Entity in this report and is consolidated in the financial statements. Where PureTech does not maintain control, the entity is referred to as a Non-Controlled Founded Entity in this report and is not consolidated in the financial statements. As of December 31, 2020, Controlled Founded Entities include Follica Incorporated, Vedanta Biosciences, Inc., Sonde Health, Inc., Alivio Therapeutics, Inc. and Entrega, Inc., and Non-Controlled Founded Entities include Gelesis, Inc., Karuna Therapeutics, Inc., Akili Interactive Labs, Inc., Vor Biopharma Inc. Relevant ownership interests for Founded Entities were calculated on a diluted basis (as opposed to a voting basis) as of December 31, 2020, including outstanding shares, options and warrants, but excluding unallocated shares authorized to be issued pursuant to equity incentive plans. Karuna ownership and Vor ownership were calculated on an outstanding voting share basis as of April 30, 2021. Akili ownership was calculated on a diluted basis as of May 25, 2021. On June 10, 2021, Alivio Therapeutics, Inc. became a wholly-owned subsidiary of PureTech. Gelesis ownership was calculated on a diluted basis as of June 30, 2021. Vedanta ownership was calculated on a diluted basis as of July 16, 2021. With the exception of Plenity and EndeavorRx, candidates are investigational and have not been cleared by the FDA for use in the United States. 
³ Funding figure includes private equity financings, loans and promissory notes, public offerings or grant awards. Funding figure excludes future milestone considerations received in conjunction with partnerships and collaborations such as those with Boehringer Ingelheim, Imbrium Therapeutics L.P., Shionogi & Co., Ltd. or Eli Lilly. Funding figure does not include Vor’s gross proceeds of $203.4 million from its February 2021 post-period IPO or Karuna’s gross proceeds of $269.8 million from its February 2021 post-period follow-on offering. Calculated as of January 1, 2017 to December 31, 2020. 
⁴ These therapeutic candidates are regulated as devices and their development has been approximately equated to phases of clinical development.
⁵ Important Safety Information: Patients who are pregnant or are allergic to cellulose, citric acid, sodium stearyl fumarate, gelatin, or titanium dioxide should not take Plenity. To avoid impact on the absorption of medications: For all medications that should be taken with food, take them after starting a meal. For all medications that should be taken without food (on an empty stomach), continue taking on an empty stomach or as recommended by your physician. The overall incidence of side effects with Plenity was no different than placebo. The most common side effects were diarrhea, distended abdomen, infrequent bowel movements, and flatulence.

⁶ Contingent on FDA review of the research plan.
⁷ EndeavorRx is indicated to improve attention function as measured by computer-based testing in children ages 8-12 years old with primarily inattentive or combined-type ADHD, who have a demonstrated attention issue. Patients who engage with EndeavorRx demonstrate improvements in a digitally assessed measure Test of Variables of Attention (TOVA) of sustained and selective attention and may not display benefits in typical behavioral symptoms, such as hyperactivity. EndeavorRx should be considered for use as part of a therapeutic program that may include clinician-directed therapy, medication, and/or educational programs, which further address symptoms of the disorder. EndeavorRx is available by prescription only. It is not intended to be used as a stand-alone therapeutic and is not a substitution for a child’s medication.
