The Reverse Stock Split is intended for the Company to regain compliance with a minimum bid price of $1.00 per share for continued listing on Nasdaq, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Requirement”). Nasdaq previously provided the Company until February 16, 2026 to regain compliance. To regain compliance, the closing bid price of the Company’s ordinary shares must meet or exceed $1.00 per share for a minimum of ten consecutive business days during this period. There can be no assurance that the Company will be able to regain compliance with the Minimum Bid Requirement.

Pursuant to (i) the warrants to purchase 572,514 Class A ordinary Shares, expiring on November 24, 2026, with an exercise price of $30.24, (ii) the warrants to purchase 28,626 Class A ordinary Shares, expiring on November 24, 2026, with an exercise price of $28.80,(iii) the warrants to purchase 604,147 Class A ordinary Shares, expiring on January 30, 2027, with an exercise price of $30.24, (iv) the warrants to purchase 30,207 Class A ordinary Shares, expiring on January 30, 2027, with an exercise price of $26.70, and (v) the warrants to purchase 18,791 Class A ordinary Shares, expiring on June 3, 2027, with an exercise price of $15.30, the exercise price will be adjusted by dividing the number of ordinary shares into which the options, warrants and other convertible securities are exercisable or convertible by sixty (60) and multiplying the exercise or conversion price thereof by sixty (60), all in accordance with the terms of the plans, agreements or arrangements governing such warrants and subject to rounding to the nearest whole share.

Pursuant to (i) the warrants issued to purchase 1,945,333 Class A ordinary Shares, expiring on April 22, 2030, with an exercise price of $1.3552, and (ii) the warrants to purchase 1,070,719 Class A ordinary Shares, expiring on June 29, 2034, with an exercise price of $5.4383, if the Warrant Event Market Price (defined below) is less than the exercise price then in effect (after giving effect to the adjustment described in the paragraph above), then on the 16^th trading day immediately following such Share Combination Event, the exercise price then in effect on such 16^th trading day shall be reduced (but in no event increased) to the Warrant Event Market Price. For the avoidance of doubt, if the adjustment in the immediately preceding sentence would otherwise result in an increase in the Exercise Price hereunder, no adjustment shall be made. “Warrant Event Market Price” means the quotient determined by dividing (x) the sum of the VWAP of the Class A ordinary shares for each of the five (5) lowest trading days during the twenty (20) consecutive trading day period ending and including the trading day immediately preceding the sixteenth (16th) trading day after the date of the Reverse Stock Split, divided by (y) five (5). In addition, the number of Class A ordinary shares underlying such warrants shall be adjusted proportionally so that the aggregate exercise price payable by the holder for the adjusted number of warrant shares shall be the same as the aggregate exercise price in effect immediately prior to such adjustment.

Pursuant to (i) a Series A-1 Senior Secured Convertible Note in the principal amount of $10,000,000 maturing on July 16, 2029, with a conversion price of $0.32, (ii) a Series B-1 Senior Secured Convertible Note in the principal amount of 5,000,000 maturing on July 16, 2029, with a conversion price of $0.30, and (iii) a Series C-1 Senior Secured Convertible Note in the principal amount of $1,338,506 maturing on July 31, 2029, with a conversion price of $0.395, if the Note Event Market Price (defined below) is less than the exercise price then in effect (after giving effect to the adjustment described in the paragraph above), then on the 16^th trading day immediately following such Share Combination Event, the exercise price then in effect on such 16^th trading day shall be reduced (but in no event increased) to the Note Event Market Price, subject to a floor price of $3.354 for Series A-1 and Series B-1 Senior Secured Convertible Note, and $4.74 for Series C-1 Senior Secured Convertible Note, as adjusted to reflect the Reverse Stock Split. For the avoidance of doubt, if the adjustment in the immediately preceding sentence would otherwise result in an increase in the Exercise Price hereunder, no adjustment shall be made. “Note Event Market Price” means the quotient determined by dividing (x) the sum of the VWAP of the Class A ordinary shares for each of the five (5) trading days with the lowest VWAP of the Class A ordinary shares during the fifteen (15) consecutive trading day period ending and including the trading day immediately preceding the sixteenth (16th) trading day after the date of the Reverse Stock Split, divided by (y) five (5).

Attached to this report on Form 6-K (this “Report”) as Exhibit 1.1 is a copy of such sixth amended and restated memorandum and articles of association.
