CAMBRIDGE, Mass., July 18, 2025 (GLOBE NEWSWIRE) -- Generation Bio Co. (Nasdaq: GBIO), a biotechnology company working to change what’s possible for people living with T cell-driven autoimmune diseases, today announced that it will implement a 1-for-10 reverse stock split of the issued shares of the Company’s common stock (“Reverse Stock Split”), effective at 5:00 pm Eastern Time on July 21, 2025. The Reverse Stock Split was approved by the Company’s stockholders at the Company’s Annual Meeting of Stockholders held on June 4, 2025, with the final ratio subsequently determined by the Company’s Board of Directors. One of the primary goals of the Reverse Stock Split is to increase the per-share market price of the Company’s common stock to enable the Company to regain compliance with the minimum bid price requirement for continued listing on the Nasdaq Global Select Market.

The Company’s common stock is expected to begin trading on a split-adjusted basis when the markets open on July 22, 2025 under the Company’s existing trading symbol “GBIO” with the new CUSIP number 37148K 209.

At the effective time of the Reverse Stock Split, every ten shares of the Company’s issued and outstanding common stock will be automatically reclassified and combined into 1 share of common stock. This will reduce the number of issued and outstanding shares of common stock from approximately 67.3 million shares to approximately 6.7 million shares. The Reverse Stock Split will not change the number of authorized shares of the Company’s common stock or the par value of the common stock. Proportionate adjustments will be made to the number of shares of common stock available for issuance under the Company’s equity incentive plans and the number of shares underlying, and the exercise prices of, outstanding equity awards under such plans in accordance with their respective terms and as described in the Company’s proxy statement for the Annual Meeting of Stockholders as filed with the Securities and Exchange Commission on April 23, 2025 (the “Proxy Statement”).

No fractional shares will be issued, if, as a result of the Reverse Stock Split, a stockholder would otherwise become entitled to a fractional share because the number of shares of common stock they hold before the Reverse Stock Split is not evenly divisible by the split ratio. Instead, each stockholder will be entitled to receive a cash payment in lieu of a fractional share.

Computershare Trust Company, N.A., is acting as the exchange agent and transfer agent for the Reverse Stock Split. Stockholders holding their shares electronically are not required to take any action to receive post-split shares. Stockholders owning shares through a bank, broker or other nominee will have their positions adjusted to reflect the Reverse Stock Split and will receive payment for any fractional shares in accordance with their respective bank’s, broker’s, or nominee’s particular processes.

About Generation Bio

Generation Bio is a biotechnology company working to change what’s possible for people living with T cell-driven autoimmune diseases. The Company is developing redosable therapeutics that reprogram T cells in vivo to reduce or eliminate the production and persistence of autoreactive T cells, which erroneously recognize and attack the body’s own tissues, causing autoimmune diseases. Generation Bio’s innovative approach leverages cell-targeted lipid nanoparticles (ctLNP) to selectively deliver small interfering RNA (siRNA) to T cells. This combination of selective delivery and an intracellular, genetically precise mechanism of target engagement could unlock a series of high-value, historically undruggable disease-driving genes in autoimmunity.
