Akili Interactive, a Leader in Digital Medicine, to Become Publicly Traded Through Combination with Social Capital Suvretta Holdings Corp. I

BOSTON, Mass. and PALO ALTO, Calif. – January 26, 2022 – Akili Interactive (“Akili” or the “Company”), a leading digital medicine company developing cognitive treatments through game-changing technologies, has 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.” As a public company with world-class backing and strong financial flexibility, Akili will be positioned to pioneer a new class of digital medicines for millions of people living with cognitive impairment.

New Digital Approach to Cognitive Medicine

The Akili software platform was built on the belief that directly engaging brain function is the next frontier of science and medicine. Cognitive impairments – including poor concentration, memory loss, difficulties learning new skills, and difficulties with decision making – are in aggregate among the largest unmet medical needs, and are increasingly recognized as contributing to or associated with dozens of chronic diseases and acute illnesses, including attention-deficit/hyperactivity disorder (ADHD), major depressive disorder (MDD), multiple sclerosis (MS), and autism spectrum disorder (ASD), as well as postoperative cognitive dysfunction and COVID-19 “brain fog.”

Despite the rapidly growing prevalence of these conditions, the acute exacerbation of these issues by the pandemic’s impact, and the chronic, escalating cognitive overload from the proliferation of on-demand attention-capturing technology, there has been limited innovation of novel treatment options.

Specifically, current treatment options are designed to focus on symptoms and coping strategies instead of directly targeting cognitive functioning. These therapeutic shortfalls are especially concerning for younger populations who are potentially facing a lifetime of managing these conditions.

Akili’s First-of-Its-Kind, Clinically Validated Therapeutic

By harnessing advances in cognitive neuroscience and consumer technology, Akili is changing the neuropsychiatric treatment paradigm. Akili’s patented and clinically validated technology platform represents a new category of software-based medicine: advanced and proprietary digital therapeutics that are designed to directly target neural physiology to better serve the needs of patients and their families.

Akili’s core therapeutic engine, the Selective Stimulus Management Engine (SSMETM), is specifically designed to target and activate neural systems involved in attentional control. This core platform has the potential to be applied across a diverse set of indications within psychiatry and neurology. Backed by robust clinical research, Akili’s treatments are delivered to patients through engaging interactive mobile games, personalized to each individual and built to feel like high-end entertainment products.

The SSMETM technology has already demonstrated proof-of-concept in controlled trials targeting attention and cognitive dysfunction in ADHD, ASD, MS, and MDD. Built on the SSMETM technology, Akili developed EndeavorRx^®, the first-ever FDA-cleared prescription video game and the first-ever FDA- cleared commercial product indicated to improve attention function in children between the ages of 8 to 12 years with primarily inattentive or combined-type ADHD (see full indication below).

Management Comments

Eddie Martucci, Chief Executive Officer of Akili, said: “This transaction represents the next step in our journey to become the world’s leading digital medicine company directly targeting neurological function. Over the past 10 years, we have created a platform representing a new era of cognitive medicine, driven by our fundamental focus on patients, advanced science and proprietary technology, and the mission-driven hard work of our entire team. We believe medicine now can be both effective and engaging. Social Capital Suvretta shares our vision for the future, and we look forward to applying our combined experience as we drive the commercialization of our platform and advance our deep pipeline of prescription digital therapeutics to help people living with cognitive impairments across the globe.”

Chamath Palihapitiya, Founder and CEO of Social Capital and Chairman and CEO of SCS, commented: “Akili is taking a new approach to cognitive science – using software to target our underlying cognitive function and creating an entirely new class of medicine as a byproduct. With its first-ever, clinically validated digital therapeutic (EndeavorRx^®), Akili has the unique opportunity to change how we treat pediatric ADHD. They have also laid the groundwork to treat a wide range of other cognitive issues affecting tens of millions of people around the world.”

Kishen Mehta, Portfolio Manager of the Averill strategy at Suvretta Capital Management and President of SCS, said: “Akili has created a unique disease-agnostic technology platform with an advanced pipeline of product candidates across multiple indications where proof-of-concept has already been achieved. The Company is leading the advancement of digital cognitive therapies with an FDA-cleared product already on the market, and we believe Akili has only just scratched the surface of this new and exciting field of medicine. We look forward to working with Akili to accelerate the Company’s growth and allow it to continue developing treatment options for the hundreds of millions of people living with cognitive impairments.”

Transaction Overview

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 the Company, 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. All references to available cash from the trust account and retained transaction proceeds are subject to any redemptions by the public shareholders of SCS and payment of transaction expenses. Akili plans to use the net proceeds to help fund the Company’s go-to-market strategy, to further advance its pipeline of prescription digital therapeutics targeting a range of chronic and acute cognitive disorders, for other general corporate purposes.

Existing Akili shareholders will roll 100% of their equity into the combined company and will be eligible to receive additional SCS shares pursuant to an earnout based on the combined company’s future stock performance.

Chamath Palihapitiya is expected to join Akili’s board of directors as chair, upon the close of the transaction.

The proposed business combination, which has been unanimously approved by the boards of directors of both Akili and SCS, is expected to close in mid-2022, subject to approval by SCS’s and Akili’s shareholders, regulatory approvals, and other customary closing conditions.

EndeavorRx^® Indication and Overview

EndeavorRx^® is the first-and-only FDA-cleared treatment delivered through a video game experience. EndeavorRx^® is indicated to improve attention function as measured by computer-based testing in children ages 8 to 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. The most common side effect observed in children in EndeavorRx^®’s clinical trial was a feeling of frustration, as the game can be quite challenging at times. No serious adverse events were associated with its use. EndeavorRx^® is recommended to be used for approximately 25 minutes a day, 5 days a week, over initially at least 4 consecutive weeks, or as recommended by your child’s health care provider.
