reverse stock split financial

"the reverse stock split of the Company’s ordinary shares will begin trading"

A reverse stock split is when a company reduces the number of its shares outstanding, making each share more valuable. For example, if you own 100 shares worth $1 each, a 1-for-10 reverse split would turn your 100 shares into 10 shares worth $10 each. Companies often do this to boost their stock price and appear more stable to investors.

Nasdaq Capital Market financial

"ordinary shares will begin trading on the Nasdaq Capital Market"

The Nasdaq Capital Market is a platform where smaller, emerging companies can list their shares for trading by investors. It provides these companies with access to funding and visibility, helping them grow, much like a local marketplace where new vendors can introduce their products to potential customers. For investors, it offers opportunities to discover early-stage companies with growth potential.

CUSIP number financial

"The new CUSIP number of the Company’s ordinary shares will be G8267K190"

A CUSIP number is a nine-character code that uniquely identifies a specific U.S. or Canadian stock, bond, or other security, similar to a barcode or a social-security number for a financial instrument. It matters to investors because it removes confusion between similar securities, ensures trades and settlements are applied to the correct issue, and helps locate official documents and transaction records quickly.

ISIN code financial

"the new ISIN code will be IE0008D7EWV5"

An ISIN code is a unique identifier for a specific financial asset, like a stock or bond, similar to a product's barcode. It helps investors, traders, and banks quickly and accurately find and track that asset across different markets worldwide. This makes buying, selling, and managing investments more organized and reliable.

forward-looking statements regulatory

"The information in this press release includes “forward-looking statements” within the meaning"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Upon the opening of business on May 11, 2026, 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 G8267K190 and the new ISIN code will be IE0008D7EWV5.

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 20:1, every 20 ordinary shares of the Company with a nominal value of $0.00000000012219451015625 per share will be automatically combined into one (1) ordinary share with a nominal value of $0.000000002443890203125 per share.

The Reverse Stock Split will reduce the number of outstanding shares of the Company from approximately 12 million to 614,000 and will affect all outstanding ordinary shares. Every 20 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 20 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.
