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’ boards of directors) or direct the management and development efforts for these entities. Consequently, not all such entities are consolidated in the Company's 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 Company's financial statements. As of June 30, 2021, PureTech's Controlled Founded Entities included Follica Incorporated, Vedanta Biosciences, Inc., Sonde Health, Inc. and Entrega, Inc., and PureTech's Non-Controlled Founded Entities included 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 June 30, 2021, including outstanding shares, options and warrants, but excluding unallocated shares authorized to be issued pursuant to equity incentive plans. Vedanta ownership was calculated on a diluted basis as of July 16, 2021. Vor ownership was calculated on an outstanding voting share basis as of November 5, 2021. Karuna ownership was calculated on an outstanding voting share basis as of November 9, 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. Calculated as of January 1, 2017 to June 30, 2021. 
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.

⁶ 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.

⁹ This represents a non-IFRS measure used by management for planning and reporting purposes. Please see below for a reconciliation of this measure to consolidated cash and cash equivalents, which is the most directly comparable measure calculated in accordance with IFRS: 

PureTech Level Cash and Cash Equivalents is defined as cash and cash equivalents held at PureTech Health plc and its wholly-owned subsidiaries only. PureTech Level Cash and Cash Equivalents is an alternative performance measure which is adjusted and constitutes a non-IFRS measure. We believe that these non-IFRS performance measures, when provided in combination with IFRS measures, will provide investors, analysts and other stakeholders with helpful complementary information to better understand our financial position from period to period. The measures are not substitutable for IFRS measures and should not be considered superior to measures presented in accordance with IFRS.
