Completion of 1-for-10 Reverse Stock Split

On July 9, 2026, Generation Income Properties, Inc. (the “Company”) completed its previously announced reverse stock split of shares of the Company’s common stock (the “Common Stock”) at a ratio of one share for every ten shares outstanding (the “Reverse Stock Split”). The Reverse Stock Split took legal effect at 5:00 p.m. Eastern Time on July 9, 2026 (the “Effective Time”) and automatically converted every ten shares of Common Stock outstanding at that time into one share of Common Stock.

The Reverse Stock Split affected all holders of Common Stock uniformly and did not affect any common stockholder’s percentage ownership interest in the Company, except for de minimis changes as a result of the issuance of fractional shares, as described under “Charter Amendment” below. Holders of Common Stock were not required to take any action as a result of the Reverse Stock Split. Their accounts were automatically adjusted to reflect the number of shares owned.

At the market open on July 10, 2026 (the first business day after the Effective Time), the Common Stock will begin trading on a split-adjusted basis on The Nasdaq Capital Market under a new CUSIP number (37149D402). The Company’s trading symbol for its Common Stock will remain unchanged.

As a net result of the Reverse Stock Split, the number of shares of Common Stock issued and outstanding decreased from 10,304,015 shares to approximately 1,030,402 shares as of the Effective Time. The total number of authorized shares of Common Stock will remain unchanged.

The Reverse Stock Split will also result in proportional adjustments being made to all outstanding warrants, restricted stock, restricted stock units, or similar securities entitling their holders to receive or purchase shares of Common Stock. Specifically, the Company’s publicly traded warrants are being adjusted such that each warrant shall be exercisable for 0.10 shares of Common Stock and the exercise price of the warrants is adjusted on 10:1 basis to increase the exercise price from $10.00 per share to $100.00 per share.

Charter Amendment

In connection with and to implement the Reverse Stock Split, on July 8, 2026, the Company filed Articles of Amendment to its charter with the State Department of Assessments and Taxation of Maryland that provided for a 1-for-10 Reverse Stock Split of the Common Stock, effective at 5:00 p.m. Eastern Time on July 9, 2026 (the “Amendment”). The Amendment became effective on July 9, 2026. No fractional shares of Common Stock will be issued in connection with the Reverse Stock Split. Any fraction of a share of Common Stock that would be created as a result of the Reverse Stock Split will be rounded up to the next whole share.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 7.01 Regulation FD Disclosure.

On July 8, 2026, the Company issued a press release announcing the completion of the Reverse Stock Split. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

The information in this Item 7.01 and Exhibit 99.1 attached hereto is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that Section, nor shall it be deemed incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof, regardless of any general incorporation language in such filing.

Item 8.01 Other Events.

The information provided in Item 5.03 is hereby incorporated by reference.

The Company has a registration statement on Form S-8 (File No. 333-261098) on file with the Securities and Exchange Commission (the “SEC”). SEC regulations permit the Company to incorporate by reference future filings made with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, prior to the termination of the offerings covered by registration statements filed on Form

S-3, Form S-1 or Form S-8. The information incorporated by reference is considered to be part of the prospectus included within such registration statement. Information in this Item 8.01 of this Current Report on Form 8-K is therefore intended to be automatically incorporated by reference into such registration statement listed above, thereby amending it. Pursuant to Rule 416(b) under the Securities Act, the amount of undistributed shares of Common Stock deemed to be covered by the effective registration statement of the Company described above is proportionately reduced to give effect to the Reverse Stock Split.

ARTICLES OF AMENDMENT

Generation Income Properties, Inc., a corporation organized and existing under and by virtue of the General Corporation Law of the State of Maryland (the “Corporation”), DOES HEREBY CERTIFY to the State Department of Assessments and Taxation of Maryland that:

FIRST: Section 4.02(f) of Article IV of the charter of the Corporation, as amended on October 12, 2020 (the “Charter”), is hereby amended by inserting a new subsection (f) as follows:

“(f) Reverse Stock Split. Effective as of 5:00 PM ET on July 9, 2026 (the “Effective Date”), each ten (10) shares of Common Stock issued and outstanding or held in treasury immediately prior to the Effective Date shall be reclassified and combined into one (1) validly issued, fully paid and non-assessable share of Common Stock without any further action by the Corporation or any holder thereof, subject to the treatment of fractional share interests as described below (the “Reverse Stock Split”). The Reverse Stock Split shall occur without any further action on the part of the Company or the holder thereof and whether or not certificates representing such holder’s shares prior to the Reverse Stock Split are surrendered for cancellation. No fractional interest in a share of Common Stock shall be deliverable upon the Reverse Stock Split. Stockholders who otherwise would be entitled to receive fractional shares of Common Stock because they hold a number of shares not evenly divisible by the Reverse Stock Split ratio will automatically be entitled to receive an additional fraction of a share of Common Stock to round up to the next whole share. Each certificate that immediately prior to the Effective Date represented shares of Common Stock (“Old Certificate”), shall thereafter represent that number of shares of Common Stock into which the shares of Common Stock represented by the Old Certificate shall have been combined, plus any additional fraction of a share of Common Stock to round up to the next whole share.”

SECOND: The directors of the Corporation duly approved and adopted the foregoing amendment by the vote required under Maryland law and the charter and bylaws of the Corporation. Pursuant to Section 2-309(e) of the Corporations and Associations Article of the Annotated Code of Maryland, stockholder approval of this charter amendment is not required.

THIRD: The total number of shares of stock that the Corporation has the authority to issue is not changed by the foregoing amendment to the charter.

IN WITNESS WHEREOF, the undersigned acknowledges these Articles of Amendment to be the corporate act of the Corporation and as to all matters of facts required to be verified under oath, the undersigned acknowledges that to the best of such officer’s knowledge, information and belief, these matters and facts are true in all material respects and that this statement is made under the penalties for perjury.

IN WITNESS WHEREOF, Generation Income Properties, Inc. has caused these Articles of Amendment to be signed and acknowledged in its name and on its behalf by its Chief Executive Officer and attested by its Chief Executive Officer as of the 8th day of July, 2026.

The new CUSIP number following the Reverse Stock Split will be 37149D402. The Company filed Articles of Amendment to its charter with the Maryland Secretary of State on July 8, 2026 to effect the Reverse Stock Split.

The Reverse Stock Split will affect all shareholders uniformly and will not alter any shareholder’s percentage ownership interest in the Company, except to the extent that the Reverse Stock Split results in that shareholder owning a fractional share as described in more detail below.

The Reverse Stock Split will reduce the number of shares of common stock issued and outstanding from approximately 10,304,015 to approximately 1,030,402. The total number of authorized shares of common stock will remain unchanged. No fractional shares will be issued in connection with the Reverse Stock Split. Any fraction of a share of common stock that would be created as a result of the Reverse Stock Split will be rounded up to the next whole share.

Specifically, the Company’s publicly traded warrants are being adjusted such that each warrant shall be exercisable for 0.10 shares of the Company’s common stock and the exercise price of the warrants is adjusted on a 10:1 basis to increase the exercise price from $10.00 per share to $100.00 per share.
