Side Letter and Fourth Closing

As previously reported, on February 6, 2025 and March 31, 2025, Reborn Coffee, Inc. (the “Company”) entered into a Securities Purchase Agreement (“Securities Purchase Agreement”) with the purchasers named therein (the “Arena Investors”), which was amended on March 28, 2025 (the “Securities Purchase Agreement Amendment”). Under the Securities Purchase Agreement, the Company agreed to issue 10% original issue discount secured convertible debentures (“Debentures”) in a principal amount of up to $10,000,000, divided into up to four separate tranches that are each subject to certain closing conditions (the “Offering”). The conversion price per share of each Debenture, subject to adjustment as provided therein, is equal to 92.5% of the lowest daily VWAP (as defined in the Debentures) of the Company’s shares of common stock, par value $0.0001 per share (“Common Stock”) during the five trading day period ending on the trading day immediately prior to delivery or deemed delivery of the applicable Conversion Notice (as defined in the Debentures). The Debentures accrue interest at a rate of 10% per annum paid in kind, unless there is an event of default in which case the Debentures will accrue interest at a default rate.

Upon the consummation of the closing of each tranche, the Company also agreed to issue common stock purchase warrants (“Warrants”) to each Arena Investor who participates in such closing. The Warrants will: (i) provide for the purchase by the applicable Arena Investor of a number of shares of Common Stock equal to 20% of the total principal amount of the related Debenture purchased by the Arena Investor on the applicable closing date divided by 92.5% of the lowest daily VWAP of Common Stock for the five consecutive trading day period ended on the last trading day immediately preceding such closing date and (ii) be exercisable at an exercise price equal to 92.5% of the average of the lowest daily VWAP of the Common Stock over the consecutive trading days immediately preceding the delivery of the applicable Notice of Exercise (as defined in the Warrants).

On July 31, 2025, the Company and the Arena Investors entered into a side letter agreement (the “Side Letter”). Under the Side Letter, the Company and the Arena Investors agreed to enter into the closing of the fourth Tranche (the “Fourth Closing”) pursuant to the Securities Purchase Agreement and that the aggregate principal amount of the Fourth Closing will be $833,333. As conditions to the Fourth Closing, the Company further agreed to (i) issue to the Arena Investors an amount of shares of Common Stock (the “Incentive Shares”) equal to an aggregate of $175,000 divided by the lowest daily VWAP of the Common Stock in the five (5) trading Days immediately preceding the date of closing of the fourth tranche (the “Fourth Closing Date”), and (ii) notwithstanding the provisions of Section 2.1(b) of the Securities Purchase Agreement, issue additional Warrants to the Arena Investors pursuant to which the Arena Investors may purchase their pro rata share of an amount of shares of Common Stock equal to 40% of the total aggregate principal amount of the Debentures being issued on the Fourth Closing Date divided by 92.5% of the lowest daily VWAP of the Common Stock during the five (5) consecutive trading days period ended on the last trading day immediately preceding the Fourth Closing Date. The Company also agreed in the Side Letter that it will cause the Incentive Shares to be registered in the same registration statement to be filed to register the shares of Common Stock underlying the Debentures and Warrants. As a further condition to the Fourth Closing, the Company also agreed to allocate the proceeds received in the Fourth Closing according to the terms of the Side Letter.

The Fourth Closing was consummated on July 31, 2025 and the Company issued to the Arena Investors Debentures in an aggregate principal amount of $833,333 (the “Fourth Closing Debentures”). The Fourth Closing Debentures were sold to the Arena Investors for a purchase price of $750,000, representing an original issue discount of ten percent (10%). The Company also issued to the Arena Investors 136,483 Warrants in connection with the Fourth Closing (the “Third Closing Warrants’).

The foregoing descriptions of the Warrants, the Securities Purchase Agreement, the Securities Purchase Agreement Amendment and the Side Letter are qualified in their entirety by reference to the full text of such agreements, copies of which are attached to this Current Report on Form 8-K as Exhibits 4.1, 10.1, 10.2, and 10.3, respectively, and each of which is incorporated herein in its entirety by reference.
