NEW YORK, Oct. 08, 2025 (GLOBE NEWSWIRE) -- Synbio International Inc. (OTC: SYIN) (“Synbio” or the “Company”) is pleased to announce the execution of a Share Purchase Agreement and Warrant Agreement (SPA) with FacialDx, Inc., further strengthening the strategic partnership established under the Clinical Trial License Agreement (CTLA) signed earlier this year.

These agreements strengthen Synbio’s partnership with FacialDx and extend the benefits to Synbio shareholders through an equity stake in FacialDx’s facial analysis technology and future revenues. Together, the companies are building a long-term collaboration that combines FacialDx’s AI-powered depression screening platform with Synbio’s proven clinical trial expertise.

Overview of the Agreements

Under the Share Purchase Agreement, Synbio will acquire 100,000 Class A common stock in FacialDx, establishing Synbio as an equity holder in the company. The SPA contemplates staged funding commitments totalling US$200,000, payable across four tranches over the next 12 months.

Importantly, Synbio also retains the right, subject to FDA approval, to convert up to US$2.5 million in future clinical trial expenditures into additional shares of FacialDx at today’s valuation, offering Synbio shareholders meaningful upside potential as FacialDx’s valuation increases through commercial and regulatory milestones.

As part of the broader collaboration, Synbio has issued a Common Stock Purchase Warrant to FacialDx, granting the right to purchase 30,000,000 of its common stock at an exercise price of $0.001 per share, exercisable upon FDA approval.

These supplementary agreements are directly related to and build upon the Clinical Trial License Agreement (CTLA) signed earlier this year, under which Synbio will conduct trials to clinically validate FacialDx’s software for screening of clinical depression.

Establishment of a Joint Trial Committee

A key feature of the SPA is the formation of a Joint Trial Oversight Committee, tasked with ensuring scientific rigor, regulatory alignment, and efficient trial execution.   The committee will review trial design, progress, and data integrity; provide recommendations at key milestones; facilitate transparent decision-making; and optimize study outcomes to maximize the likelihood of FDA approval.   This governance framework ensures that both companies remain strategically aligned while maintaining scientific and regulatory excellence throughout the trial process

Benefits to Synbio Shareholders

The SPA and Warrant Agreements mark a pivotal step in Synbio’s mission to build shareholder value through strategic investments in high-growth technologies. They offer the following benefits:

• Indirect Ownership of Facial IP: Through Synbio’s equity position, shareholders gain indirect ownership in FacialDx’s proprietary AI-powered facial recognition software.
• Enhanced Probability of FDA Success: The joint trial committee structure ensures rigorous oversight, greatly improving the chances of regulatory success.
• Participation in Multi-Sector Revenue: As a shareholder in FacialDx, Synbio will participate in FacialDx’s revenue streams beyond mental health, as the software expands into markets for other mental health conditions.
• Exposure to AI-Driven Healthcare Growth: FacialDx operates at the intersection of artificial intelligence and health & wellness, positioning Synbio investors to benefit from one of the fastest-growing segments of the digital healthcare industry.
• Strategic Validation Pathway: Synbio’s leadership in managing clinical validation ensures rigorous scientific evaluation, increasing the likelihood of FDA clearance and commercial adoption.
  
  

FacialDx: Expanding Beyond Mental Health

While FacialDx’s primary focus is on the early detection of mental health conditions, its facial analysis platform is being developed for multiple health & wellness applications, including Traumatic Brain Injury, Chronic Pain Assessment, Sleep and Fatigue Disorders. This technology leverages machine learning and facial micro-expression mapping to deliver real-time, non-invasive clinical insights across a growing range of conditions.

Funding

Synbio is currently evaluating a range of funding options to support its clinical and commercial milestones under these agreements. The Company’s objective is to secure the most advantageous structure for shareholders, balancing capital efficiency with long-term value creation. Further details will be announced shortly as the preferred funding path is finalized.
