Upon the opening of business on November 18, 2025, SMX (Security Matters) Public Limited Company’s (the “Company”) ordinary shares will begin trading on the Nasdaq Capital Market (“Nasdaq”) on a post-reverse stock split basis under the current symbol “SMX”. The new CUSIP number of the Company’s ordinary shares will be G8267K 307 and the new ISIN code will be IE000UPDVNX9.

On May 2, 2025, the Company’s Shareholders approved a proposal to amend the Company’s constitution to allow the Company’s Board of Director’s to consolidate and/or divide all or any of the Company’s classes of shares as the Board of Directors sees fit. As such, Shareholder approval was not required to effect the reverse stock split.

The Company’s Board of Directors’ fixed the split ratio at 8:1, every eight (8) ordinary shares of the Company with a nominal value of $0.00000000000312817946 per share will be automatically combined into one (1) ordinary share with a nominal value of $0.00000000002502543568 per share.

The Reverse Stock Split will reduce the number of outstanding shares of the Company from 8,404,581 to 1,050,572 and will affect all outstanding ordinary shares. Every 8 outstanding ordinary shares will be combined into and automatically become 1 post-Reverse Stock Split ordinary share. No fractional shares will be issued in connection with the reverse stock split. Instead, the Company will aggregate the fractional entitlements of shareholders who otherwise would be entitled to receive fractional shares because they hold a number of ordinary shares not evenly divisible by 8 ordinary shares pursuant to the reverse stock split or they hold less than the number of ordinary shares which should be consolidated into one ordinary share pursuant to the reverse stock split and, to the extent possible, sell such aggregated fractional ordinary shares on the basis of prevailing market prices at such time.

After the Reverse Stock Split, all outstanding Company options, warrants and other applicable convertible securities, including the Company’s warrants listed on the Nasdaq Capital Market under the symbol SMXWW which will retain its existing CUSIP number, will be proportionately adjusted in accordance with their respective terms.

In connection with the Reverse Stock Split, the Company amended the Public Limited Company Constitution of SMX (Security Matters) Public Limited Company Memorandum of Association (“Amended Constitution”) to reflect the adjustment of the par value. Attached to this report on Form 6-K (this “Report”) as Exhibit 1.1 is a copy of such Amended Constitution.
