**Perpetuals (NASDAQ: PDC) Extends BayesShield AI Into Healthcare to Address the Root Cause of Diagnostic Errors**

● *Proprietary algorithm, originally built to predict trading outcomes, now targets the millions of patients harmed annually by diagnostic errors* 

● *European Institute of Management to support clinical implementation with partner hospitals through its PhD in Healthcare Studies program* 

**TOKYO, Japan / April 22, 2026 /** Perpetuals.com Ltd (Nasdaq: PDC), the AI-powered financial services company, today announced the extension of its proprietary BayesShield AI technology into healthcare. BayesShield Clinical applies the same patent-pending methodology the company developed to predict trading outcomes to a new domain: identifying which physicians in hospitals and clinics are the most accurate at diagnosing specific types of cases to ensure patients get the best health outcomes.

In the United States alone, an estimated 795,000 patients die or are permanently disabled each year due to diagnostic errors (Johns Hopkins / BMJ Quality & Safety, 2024). Cognitive biases have been associated with diagnostic inaccuracies in as many as 77% of case scenarios across systematic review studies (BMC Medical Informatics and Decision Making, 2016), and between 80% and 90% of physicians openly acknowledge practicing defensive medicine (University of Wisconsin / EQ, 2024) by ordering unnecessary tests and referring conservatively to avoid malpractice risk, which obscures their true diagnostic skill. The result is a healthcare system that spends an estimated $210 billion annually on unnecessary medical services (National Academy of Medicine, 2012) while failing to identify and leverage its best diagnosticians.

BayesShield Clinical is designed for hospitals, clinics, and health systems. It does not diagnose patients or replace physician judgment. Instead, it strips away behavioral biases, applying statistical methods to identify patterns of diagnostic strength across specific case types. Hospitals and other health care providers can use these insights for optimized case routing, second-opinion protocols, and training program design. Financial markets and clinical medicine share a common analytical problem: decisions made under uncertainty, where skill is obscured by noise, variable conditions, and behavioral bias. The company believes the same approach that identifies performance patterns in financial markets can reveal them in clinical decision-making.

"We built BayesShield to find why traders lose money, hidden under layers of behavioral noise. The same methodology works in other high-stakes decisions, including healthcare," said Patrick Gruhn, CEO of Perpetuals. "The AI platform we developed helps hospitals identify which of their physicians have statistically exceptional diagnostic patterns in specific case types, so the patient gets the best care by getting the right diagnosis from the outset."

Perpetuals has partnered with the European Institute of Management (EIM), a higher education institution offering doctoral programs, including a PhD in Healthcare Studies, to support the clinical implementation of BayesShield Clinical. Under the arrangement, Perpetuals provides the software platform while EIM works directly with partner hospitals and clinics to manage pilot deployment, trial design, and academic oversight. EIM's PhD in Healthcare Studies program will serve as the academic collaboration for the clinical pilots, with doctoral candidates contributing to the study design and analysis of outcomes. Additional hospital, health system, and research partnerships are in development as the company prepares for broader deployment.

"We are grateful to partner with Perpetuals and explore how AI systems can improve diagnostics in clinical settings," said Prof. Dr. Michael Neubert, PhD, Founder of EIM. "Joint efforts like this advance evidence-based innovation in healthcare while maintaining a clear distinction from therapeutic interventions."

BayesShield was originally developed and stress-tested in financial markets, widely considered the most adversarial, data-rich, and bias-prone decision environment. The platform is trained on over 11.7 billion actual retail trades sourced from larger derivatives trading venues.
