Insights

ABP enacts a 1-for-30 reverse split; trading adjusts Nov 3.

Abpro Holdings approved a 1-for-30 reverse split effective October 31, 2025. This consolidates share count, reducing outstanding common stock from 81,150,000 to approximately 2,705,000. The action does not change total company value by itself; it primarily alters share price and count.

Derivative securities (options and warrants) and their exercise prices will adjust in line with the split. Fractional holdings will be rounded up to the next whole share, simplifying settlements for small positions.

Trading on a split-adjusted basis begins November 3, 2025 under ticker ABP. Actual market impact depends on trading dynamics after the adjustment and holder behavior.

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

 

On October 16, 2025, Abpro Holdings, Inc. (the “Company”) filed with the Delaware Secretary of State a Certificate of Amendment to the Certificate of Incorporation of the Company (the “Certificate of Amendment”), which will become effective at 5:01 p.m. on October 31, 2025 (the “Effective Time”), to effect a one-for-thirty (1:30) reverse stock split (the “Reverse Stock Split”), of the shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”). The Reverse Stock Split was approved by the Company’s stockholders at the 2025 annual meeting of the stockholders on October 10, 2025.

 

As a result of the Reverse Stock Split, every 30 shares of issued and outstanding Common Stock will be automatically combined into one (1) issued and outstanding share of Common Stock, without any change in the par value per share. No fractional shares will be issued as a result of the Reverse Stock Split. Instead, stockholders who otherwise would have been entitled to receive fractional shares because they held a number of shares not evenly divisible by the Reverse Stock Split ratio will be entitled to receive an additional fraction of a share of Common Stock to round up to the next whole share.

 

Following the Reverse Stock Split, the number of shares of Common Stock outstanding will be proportionally reduced from 81,150,000 shares to approximately 2,705,000 shares. The shares of Common Stock underlying the Company’s outstanding stock options and warrants will be similarly adjusted along with corresponding adjustments to their exercise prices.

 

The Company’s transfer agent, Continental Stock Transfer & Trust Company, is the exchange agent for the Reverse Stock Split and will correspond with stockholders of record regarding the Reverse Stock Split. Stockholders owning shares via a broker or other nominee will have their positions automatically adjusted to reflect the Reverse Stock Split.

 

The Common Stock will begin trading on a reverse stock split-adjusted basis upon market open on November 3, 2025. The ticker symbol for the Common Stock will remain “ABP.” The new CUSIP number for the Common Stock following the Reverse Stock Split will be 000847202.

 

The forgoing description of the Certificate of Amendment does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the full text of the Certificate of Amendment, which is attached as Exhibit 3.1 to this Current Report on Form 8-K, and is incorporated herein by reference.
