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, 2021, Controlled Founded Entities include Follica Incorporated, Vedanta Biosciences, Inc., Sonde Health, Inc. and Entrega, Inc., and Non-Controlled Founded Entities include Gelesis Holdings, Inc., Karuna Therapeutics, Inc., Akili Interactive Labs, Inc., Vor Bio Inc. Relevant ownership interests for Founded Entities were calculated on a partially diluted basis (as opposed to a voting basis) as of December 31, 2021, including outstanding shares, options and warrants, but excluding unallocated shares authorized to be issued pursuant to equity incentive plans. Vor Bio, Karuna and Gelesis ownerships were calculated on a beneficial ownership basis in accordance with SEC rules as of March 4, 2022 and February 15, 2022 and March 31, 2022, respectively. With the exception of Plenity® and EndeavorRx®, candidates are investigational and have not been cleared by the FDA for use in the U.S.

¹ 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. Funding figure does not include Gelesis’ gross proceeds of approximately $105.0 million from its January 2022 SPAC merger.

⁴ These therapeutic candidates are regulated as devices and their development has been approximately equated to phases of clinical development.

⁵ Important Safety Information about Plenity®: 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.

⁷ EndeavorRx® is a digital therapeutic 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. There were no serious adverse events; 9.3% of subjects experienced side effects, including frustration, headache, dizziness, emotional reaction, nausea or aggression. EndeavorRx is only available to your patients through a prescription, and is not intended as a stand-alone therapeutic or a substitute for your patient’s medication.
