Insights

Entero executes a 1-for-3 reverse split to support Nasdaq listing compliance without changing overall ownership stakes.

Entero Therapeutics is combining every three shares of common stock into one, effective August 18, 2025. The stated goal is to lift the per-share bid price above $1.00 to meet Nasdaq Listing Rule 5550(a)(2), after stockholder approval on June 30, 2025.

The company keeps its authorization at 100,000,000 common and 10,000,000 preferred shares, and par values remain the same. Each holder’s percentage ownership and voting power in common stock is intended to remain substantially unchanged, aside from small adjustments due to cash paid in lieu of fractional shares.

The filing notes that compliance is regained only if the stock trades at or above $1.00 for at least 10 consecutive trading days and cautions that the reverse split may not sustain the higher price level. Future company disclosures may show whether this condition has been satisfied.

Item 3.03 Material Modification to Rights of Security Holders.

 

To the extent required by Item 3.03 of Form 8-K, the information contained in Item 5.03 of this Current Report on Form 8-K is incorporated herein by reference.

 

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

 

Entero Therapeutics, Inc., a Delaware corporation (the “Company”), approved a reverse stock split of the Company’s issued and outstanding shares of common stock (“Common Stock”), at a ratio of 1-for-3 (the “Reverse Stock Split”). The Reverse Stock Split was duly approved in a special meeting of the stockholders held on June 30, 2025. On August 14, 2025, the Company filed with the Secretary of State of the State of Delaware the Certificate of Amendment to its Amended and Restated Certificate of Incorporation (the “Certificate of Amendment”) to effect the Reverse Stock Split. The Reverse Stock Split will become effective as of 12:01 a.m., Eastern Time, on August 18, 2025, and the Company’s Common Stock will begin trading on the Nasdaq Stock Market on a split-adjusted basis when the market opens on August 18, 2025.

 

Reasons for the Reverse Stock Split

 

The Company is implementing the Reverse Stock Split to raise the per share bid price of the Company’s Common Stock above $1.00 per share and bring the Company back into compliance with Nasdaq Listing Rule 5550(a)(2). The Company will have regained compliance once the Company’s Common Stock trades at or above $1.00 for a minimum of 10 consecutive trading days, at which time Nasdaq will provide the Company with notice that it has regained compliance. The Company cannot provide assurance that the Reverse Stock Split will achieve the desired effects or that, if achieved, such desired effects will be sustained.

 

Effects of the Reverse Stock Split

 

Effective Date; Symbol; CUSIP Number

 

The Reverse Stock Split will become effective on August 18, 2025 (the “Effective Date”). The Common Stock will begin trading on a split-adjusted basis at the commencement of trading on the Effective Date, under the Company’s existing trading symbol “ENTO.” The new CUSIP number for the Common Stock following the Reverse Stock Split will be 33749P507.

 

Split Adjustment; Treatment of Fractional Shares

 

On the Effective Date, the total number of shares of Common Stock held by each stockholder of the Company will be exchanged for the number of shares of Common Stock equal to the number of issued and outstanding shares of Common Stock held by each such stockholder immediately prior to the Reverse Stock Split, divided by three (3). As a result, stockholders of record who otherwise would be entitled to receive fractional shares, will be entitled to receive cash (without interest) in lieu of fractional shares.

 

Certificated and Non-Certificated Shares

 

Each certificate, or book entry, that immediately prior to the Reverse Stock Split represented shares of Common Stock, will, following the Reverse Stock Split, represent that number of shares of Common Stock into which the shares of Common Stock represented by such certificate or book entry have been combined, subject to the treatment of fractional shares as described above.

 

Stockholders who hold their shares in electronic form at brokerage firms do not need to take any action, as the effect of the Reverse Stock Split will automatically be reflected in their brokerage accounts.

 

Delaware State Filing

 

The Reverse Stock Split was effected pursuant to the Company’s filing of the Certificate of Amendment with the Secretary of State of the State of Delaware. A copy of the form of the Certificate is attached as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.

 

Capitalization

 

The Company is authorized to issue 100,000,000 shares of Common Stock and 10,000,000 shares of preferred stock (the “Preferred Stock”). There will be no change to the number of authorized capital stock of the Company or to the rights limitations and privileges, including voting rights, of the Company’s designated and outstanding shares of Preferred Stock. The Reverse Stock Split will have no effect on the par value of the Common Stock or the Preferred Stock.

 

 

 

 

Immediately after the Reverse Stock Split, each Common Stockholder’s percentage ownership interest in the Company’s Common Stock and proportional voting power of the Company’s Common Stock shall remain unchanged, except for minor changes and adjustments that will result from the treatment of fractional shares. The rights and privileges of the holders of shares of Common Stock will remain unaffected by the Reverse Stock Split.

 

Item 8.01 Other Events.

 

On August 14, 2025, the Company issued a press release announcing the Reverse Stock Split. A copy of such press release is attached to this Current Report on Form 8-K as Exhibit 99.1.

FAQ

What reverse stock split did Entero Therapeutics (FWBI) approve?

Entero Therapeutics approved a 1-for-3 reverse stock split of its common stock. Every three existing shares will be combined into one share, reducing the share count while aiming to increase the per-share trading price without changing overall ownership percentages, aside from minor rounding from fractional shares.

When does Entero Therapeutics’ 1-for-3 reverse stock split take effect?

The reverse stock split becomes effective at 12:01 a.m. Eastern Time on August 18, 2025. Entero’s common stock will start trading on a split-adjusted basis that same day, with all existing certificates and book-entry positions automatically reflecting the new share count after the adjustment.

Why is Entero Therapeutics implementing a reverse stock split?

Entero Therapeutics is implementing the reverse split to raise its common stock’s per-share bid price above $1.00. This is intended to help the company regain compliance with Nasdaq Listing Rule 5550(a)(2), which requires a minimum $1.00 bid price for continued listing on the Nasdaq Capital Market.

How will fractional shares be handled in Entero Therapeutics’ reverse split?

Shareholders who would otherwise receive fractional shares after the 1-for-3 reverse split will receive cash instead. The company will pay cash, without interest, in lieu of issuing fractional common shares, simplifying post-split positions while slightly adjusting individual holdings due to rounding effects.

Does Entero Therapeutics’ reverse split change authorized shares or par value?

The reverse stock split does not change Entero’s authorized capital or par values. The company remains authorized to issue 100,000,000 common shares and 10,000,000 preferred shares, and the par value of both common and preferred stock is unchanged, preserving the existing capital structure framework after the split.

Will Entero Therapeutics shareholders’ ownership percentages change after the reverse split?

The company states each common shareholder’s percentage ownership and proportional voting power will remain unchanged after the 1-for-3 reverse split. Only minor differences may arise from the cash treatment of fractional shares, but the overall relative ownership among stockholders is intended to stay the same.

What ticker and CUSIP will Entero Therapeutics use after the reverse split?

After the reverse split becomes effective, Entero’s common stock will continue trading under the symbol ENTO on the Nasdaq Capital Market. However, the CUSIP number for the common stock will change to 33749P507, reflecting the corporate action while keeping the same market listing symbol.
