~~On April 6, 2026,~~ SMX (Security Matters) ~~Public~~PLC ~~Limited Company~~ (the “Company”) ~~issued~~may astrategically ~~press~~effect ~~release~~one ~~entitled~~or ~~“SMX~~more ~~Announces~~additional reverse stock splits from time to ~~Launch~~time ofwithout ~~Its~~further ~~Digital~~shareholder ~~Material~~approval ~~Passport~~under ~~Platform~~Ireland law; however, ~~Enabling~~there ~~Real-World~~can ~~Asset~~be ~~Tokenisation~~no ~~and~~assurance ~~Global~~that ~~Material~~the ~~Traceability~~Company will so effect additional reverse stock splits or what the ratio(s) may be for any such reverse stock split(s).” AThe ~~copy~~Company’s decision whether or not (and when) to effect additional reverse stock splits (and at what ratio to effect such reverse stock splits) will be based on a number of factors, including market conditions, existing and anticipated trading prices for the ~~press~~Ordinary ~~release~~Shares and the requirements of the Nasdaq Capital Market. The Company has historically effected reverse stock splits when there is ~~attached~~downward topressure ~~this~~on ~~Form~~the ~~6-K~~trading price of its Ordinary Shares, typically as ~~Exhibit~~a 99result of the sale into the market of registered Ordinary Shares upon the conversion of outstanding convertible promissory notes or warrants.1.

~~The~~General ~~press~~Risk ~~release~~Factor announces the launch of the Company’s Digital Material Passport Platform (“DMPP”) — a foundational system enabling the identification, tracking, and tokenisation of real-world assets (RWA) across global supply chains. The SMX DMPP has been developed to establish a secure, permission-based system that connects physical materials to digital records, creating a persistent “material memory” from origin through manufacturing, trade, and reuse. This enables materials such as plastics, gold, silver, and rare earth elements to be transformed into verified, traceable, and tradable digital assets. SMX believes that this launch positions it at the center of a potential major global shift — where verified physical materials can become financial instruments, and supply chains can become the infrastructure layer for RWA markets.

The Company’s ~~DMPP~~has ~~was~~effected ~~designed~~numerous toreverse ~~embed~~stock ~~identity~~splits ~~directly~~and ~~into~~may ~~materials~~effect ~~using~~additional ~~molecular~~reverse ~~markers,~~stock ~~linking~~splits ~~them~~in tothe afuture, ~~secure~~which ~~digital~~has in the past ~~registry,~~and could in the future have the effect of decreasing the liquidity of our Ordinary Shares and further causing the Company’s stock price to ~~enable:~~decline relative to its value before the reverse stock split.

●The Company ~~Verified~~reserves ~~RWA~~the ~~tokenisation;~~right ●to, ~~End-~~and may, strategically effect one or more additional reverse stock splits from time to~~-end~~ ~~traceability;~~time ●during ~~Audit-grade~~the remainder ~~data~~of ~~integrity~~the fiscal year ending December 31, 2026 or beyond, without further shareholder approval under Ireland law; ●however, ~~Fraud~~there can ~~prevention~~be no assurance that the Company will so effect additional reverse stock splits or what the ratio(s) may be for any such reverse stock split(s). The Company’s decision whether or not (and ~~authentication;~~when) to effect additional reverse stock splits (and ●at ~~Lifecycle~~what ratio to effect such reverse stock splits) will be based on a number of factors, including market conditions, existing and ~~multi-loop~~anticipated ~~tracking~~trading prices for the Ordinary Shares and the requirements of the Nasdaq Capital Market. The Company has historically effected reverse stock splits when there is downward pressure on the trading price of its Ordinary Shares, typically as a result of the sale into the market of registered Ordinary Shares upon the conversion of outstanding convertible promissory notes or warrants.

~~During~~The ~~April~~liquidity ~~2026~~of the Ordinary Shares has in the past, and may in the future, be affected adversely by a reverse stock split given the reduced number of shares that will be outstanding following a reverse stock split, especially if the market price of the Ordinary Shares does not increase as a result of the reverse stock split. Although the Company isbelieves ~~providing~~that ~~exclusive~~a ~~client~~higher ~~experience~~market ~~access~~price toof its ~~existing~~Ordinary ~~customers~~Shares may help generate greater or ~~other~~broader ~~relationships~~investor interest, ~~allowing~~the ~~them~~Company cannot assure you that a reverse stock split will result in a share toprice ~~engage~~that ~~directly~~will ~~with~~attract new investors and may instead carry the ~~platform~~risk of dampening the overall attractiveness of the Company’s securities. In addition, ~~onboard~~the ~~materials~~Company’s reverse stock splits have increased the number of stockholders who own odd lots (less than 100 shares) of Ordinary Shares, ~~and~~creating ~~validate~~the ~~use~~potential ~~cases~~for ~~across~~such stockholders to experience an increase in the cost of selling their ~~operations~~shares and greater difficulty effecting such sales.

~~From~~Any ~~May~~future 4,reverse ~~2026,~~stock split can also cause a decline in the ~~Company~~value ~~expects~~of the Ordinary Shares relative to ~~open~~its ~~bookings~~value ~~for~~before ~~new~~the ~~clients~~reverse stock split, ~~enabling~~and ~~broader~~the Company can make no assurance that the market ~~adoption~~price ~~across~~of ~~industries~~the ~~including~~Company’s ~~plastics,~~Ordinary Shares will remain at or above the ~~metals~~post-split price on the commencement of trading on its effective date, ~~and~~as ~~other~~many ~~materials~~times stocks decrease in value after a reverse stock split.

~~Forward~~Finally, ~~Looking~~although ~~Statements~~the Company does not believe that its reverse stock splits have violated or any further reverse stock splits will violate any particular Nasdaq rules, and the Company further believes that it is in compliance with the Nasdaq listing standards, the Company can give no assurance that the Company’s numerous prior reverse stock splits and potential future reverse stock splits will not result in Nasdaq issuing a deficiency notice or even delisting the Company from the Nasdaq Capital Market, which would have a material adverse effect on our ability to raise capital, the stock price and liquidity of the Ordinary Shares, or the value of the Ordinary Shares held by the Company’s shareholders.”
