Curative Biotechnology Announces Reverse Stock Split and Strategic Progress Toward OTCQB Uplisting

Strengthening Capital Structure and Advancing Clinical Development Strategy

Palm Beach Gardens, FL, March 23, 2026 (GLOBE NEWSWIRE) -- Curative Biotechnology, Inc. (OTC: CUBT) (“Curative” or the “Company”), a development-stage biomedical company focused on novel treatments for degenerative eye diseases, today announced a reverse stock split (“Reverse Stock Split”) of its common stock at a ratio of 1-for-150. The Reverse Stock Split became effective at 12:00 a.m. Eastern Time on March 23, 2026, and the Company’s common stock is expected to begin trading on a split-adjusted basis at market open on that date. The Company’s ticker symbol on the OTCID quotation system will temporarily change to CUBTD for a period of 20 trading days, including the effective date.

The 1-for-150 Reverse Stock Split will proportionally reduce the number of outstanding shares of the Company’s common stock from approximately 1.02 billion shares to approximately 6.8 million shares. The ownership percentage of each shareholder will remain unchanged, except for minor adjustments related to fractional shares. Proportional adjustments will also be made to the number of shares of common stock issuable upon exercise or conversion of the Company’s outstanding equity awards and warrants, as well as the applicable exercise prices.

Shares held through the Depository Trust Company (DTC) will also be proportionally reduced from approximately 266.8 million shares to approximately 1.78 million shares. These shares represent the portion of the Company’s outstanding stock currently eligible for electronic trading in the public market.

As outlined in the Company’s November 18, 2025 shareholder update, Curative continues to advance development of its metformin-based ophthalmology platform and is pursuing a manufacturing and product development agreement related to this program. The Company has received a proposal from a U.S.-based manufacturer capable of producing sterile metformin ophthalmic drops in quantities sufficient to support both an initial Phase 1 human clinical study and an initial clinical K9 study.

The planned first-in-human clinical study is expected to be conducted at the National Institutes of Health (NIH) under the Company’s Cooperative Research and Development Agreement (CRADA) for the treatment of dry Age-Related Macular Degeneration (AMD).

The Company’s initial K9 target indication is PDE6-associated retinal degeneration, a genetic early-onset retinal disease in dogs. This indication may qualify for the Center for Veterinary Medicine’s (CVM) conditional approval pathway, which permits commercialization for up to five years following demonstration of reasonable expectation of effectiveness, while additional confirmatory data is generated.

A successful K9 study in PDE6-associated retinal degeneration may also provide translational support for development of metformin-based ophthalmic formulations targeting human Retinitis Pigmentosa.

Manufacturing is anticipated to begin in mid-April 2026, and the selected facility is capable of performing required stability testing.

Curative has engaged DSI InPharmatics, a regulatory consulting firm with experience in animal health programs, to assist in development of the clinical protocol for the planned K9 study.

“Consistent with the strategic direction outlined in our November shareholder update, we continue to advance our metformin-based ophthalmology platform toward clinical development,” said Paul Michaels, Executive Chairman of Curative Biotechnology. “The reverse stock split represents an important step in positioning the Company for improved capital structure and broader investor awareness as we continue building the foundation necessary to support upcoming clinical milestones.”

The Company believes that recent strategic and operational progress may increase awareness of Curative’s development programs among a broader range of investors, including institutional investors focused on emerging biotechnology opportunities. Management continues to evaluate potential strategic relationships that could support advancement of its clinical development objectives.

Following execution of the anticipated manufacturing and product development agreement, the Company intends to submit an application to uplist its common stock to the OTCQB Venture Market. The OTCQB market tier is designed for developing companies that meet higher financial reporting standards and corporate governance requirements and may provide improved transparency and credibility with a broader range of market participants.
