Rhea-AI Filing Summary

SMX (Security Matters) Public Limited Company has filed a prospectus supplement covering the resale of up to 13,025,574 ordinary shares by selling stockholders. These shares relate to an equity line under a Standby Equity Purchase Agreement, convertible notes, and a previously agreed facility fee.

The attached Form 6-K describes a second amendment to the equity purchase agreement with Target Capital 1 LLC, increasing the investor’s commitment amount from $100,000,000 to $250,000,000. Through February 5, 2026, SMX has drawn about $8.9 million under this facility, issuing 685,471 ordinary shares to Target. The placement agent will receive tiered cash fees on future drawdowns, while the original 2% facility fee on the initial $100,000,000 commitment is confirmed as fully paid with no increase.

Insights

Capital markets and dilution analyst

SMX expands its equity line to $250M, increasing financing flexibility but also potential dilution.

SMX has amended its Standby Equity Purchase Agreement with Target Capital 1 LLC, raising the investor commitment from $100,000,000 to $250,000,000. This structure allows the company to sell ordinary shares over time, with actual usage depending on future drawdowns.

By February 5, 2026, SMX had drawn about $8.9 million and issued 685,471 ordinary shares, showing early use of the facility. A tiered placement agent fee applies: 4% on the first $20,000,000, 3% on the next $80,000,000, and 2% on the last $150,000,000.

The amendment confirms the original facility fee of 2% on $100,000,000 has been fully paid, with no extra fee for the added commitment. Future filings detailing additional drawdowns, issued shares, and cash proceeds will indicate how extensively SMX uses this expanded capacity.
