Lilly to Acquire AtaiBeckley to Advance Mental Health Pipeline

July 17, 2026 | Friday | Business Deal

Eli Lilly and Company and AtaiBeckley Inc., a clinical-stage biopharmaceutical company developing innovative therapeutics for mental health conditions, today announced a definitive agreement for Lilly to acquire AtaiBeckley.

Emerging research indicates that treatment-resistant depression and other serious mental health conditions may involve a loss of synaptic plasticity, the brain's ability to form and strengthen connections in regions critical to mood regulation. AtaiBeckley's therapies are designed to restore synaptic connectivity and aim to promote the growth of new neural connections, offering a distinct mechanism from conventional antidepressants that primarily target neurotransmitter levels.

"Treatment-resistant depression persists even after multiple treatments have failed. Millions of people are still searching for relief and desperately need a therapy that works," said Carole Ho, executive vice president and president, Lilly Neuroscience. "Advancing AtaiBeckley's investigational therapies gives us a real chance to change that."

"Across our portfolio, we're seeking to demonstrate that psychiatric illness is treatable at its biological root, not just its symptoms," said Srinivas Rao, co-founder and chief executive officer of AtaiBeckley. "Lilly's expertise and reach are expected to accelerate that work for people whose conditions have not responded to existing treatments."

"From Atai's founding, our mission has been to bring transformative mental health treatments to the patients who need them most. Joining Lilly gives this pipeline, and the patients waiting for it, the benefit of the resources and scale Lilly has to potentially advance therapies faster than we could alone. I am confident this transaction represents the best path forward for patients and shareholders," said Christian Angermayer, founder, largest shareholder, and chairman of the board, AtaiBeckley.
