A one-for-two reverse split, effective November 20, 2026, cuts shares outstanding from about 5.6 million to about 2.8 million and mechanically doubles the share price without changing any holder's equity value. It is a procedural step ahead of the Avenzo merger, which stockholders approved on November 4, 2026. The split itself does not change fundamentals, though it signals the companies are positioning the combined entity to meet Nasdaq listing standards.

❓ FAQ

Does the reverse stock split reduce the value of my RLYB shares?

No. Every two shares combine into one, so the share price doubles and each holder keeps the same percentage ownership. Only fractional shares are cashed out at fair market value on the effective date.

Will RLYB keep its ticker after the merger?

No. After the merger closes, the company plans to rename itself Avenzo Therapeutics and trade on Nasdaq under the new symbol AVZO.
