NAYA Biosciences Announces Strategic Decision to Separate Fertility and Oncology Businesses into Distinct Operations – Company Renamed “INVO Fertility, Inc.”

Public company to operate under new name and concentrate on building, acquiring and operating fertility clinics and the distribution of FDA-cleared INVOcell device

Private company to operate as NAYA Therapeutics and focus on clinical development of bifunctional antibodies

SARASOTA, Fla., April 14, 2025 (GLOBE NEWSWIRE) -- INVO Fertility, Inc., formerly known as NAYA Biosciences, Inc. (the “Company”) (Nasdaq: NAYA), a healthcare services fertility company focused on expanding access to advanced treatment through the establishment, acquisition, and operation of fertility clinics, today announced its decision to separate its fertility and oncology operations. This strategic decision to separate its two principal focus areas is expected to enable both businesses to maximize shareholder value.

In connection with the planned separation, the Company has been renamed to “INVO Fertility, Inc.” effective Monday, April 14, 2025, and its Nasdaq ticker symbol will be changed to “IVF” as soon as practicable. The Company will provide additional information on the expected date for the new symbol to go effective.

With this separation, the Company returns to its previous, exclusive focus on the fertility marketplace – the establishment, acquisition and operation of new fertility clinics and the distribution of the Company’s FDA-cleared INVOcell device.

The Company plans to divest a majority stake in its wholly owned subsidiary, NAYA Therapeutics Inc. (“NAYA TX”). Through the retention of a minority position, the Company seeks to benefit from the potential value appreciation that could be generated from the clinical development of NAYA TX's bifunctional antibodies. This revised corporate structure aims to enable both businesses to focus on their respective opportunities and operations, with the existing management team and board of directors set to lead the Company. NAYA TX will return to being a privately held biotechnology company led by its management team and board. The final separation is subject to completing definitive transaction documents and key closing conditions, including receipt of necessary approvals.

“Moving forward, we will leverage our existing, revenue-generating fertility operations with operating centers in Wisconsin, Alabama, and Georgia, to acquire and build new centers across the U.S.,” stated Steve Shum, CEO of INVO Fertility. “We believe the fertility market opportunity remains large and growing, as confirmed by the U.S. President’s recent executive order aimed at reducing the cost of IVF and expanding access to fertility services.”

“We remain enthusiastic about NAYA TX's assets and their significant potential upside, which we hope to monetize in the future through value appreciation in the minority stake we plan to retain. At the same time, the return of the two businesses to independent entities is expected to enable a more focused effort with dedicated teams. We believe the respective shareholders for each business agree and support this revised structure and approach.”

The Company previously filed an extension for the filing of its Annual Report on Form 10-K for the year ended December 31, 2024. The Company is in the process of completing its financial statements and other disclosures for the fiscal year ended December 31, 2024.

About INVO Fertility, Inc.

We are a healthcare services fertility company dedicated to expanding assisted reproductive technology (“ART”) care to patients in need. Our principal commercial strategy is focused on building, acquiring and operating fertility clinics, including “INVO Centers” dedicated primarily to offering the intravaginal culture (“IVC”) procedure enabled by our INVOcell^® medical device (“INVOcell”) and US-based, profitable in vitro fertilization (“IVF”) clinics. We have two operational INVO Centers in the United States and one IVF clinic. We also continue to engage in the sale and distribution of our INVOcell technology solution into third-party owned and operated fertility clinics. The INVOcell is a proprietary and revolutionary medical device, and the first to allow fertilization and early embryo development to take place in vivo within the woman's body. The IVC procedure provides patients with a more natural, intimate, and affordable experience in comparison to other ART treatments. We believe the IVC procedure can deliver comparable results at a fraction of the cost of traditional IVF and is a significantly more effective treatment than intrauterine insemination (“IUI”).
