Extension of Expiration Date of Warrants

Sequans Communications S.A. previously reported that, in connection with private placements of equity and secured convertible debentures, it issued warrants to purchase ordinary shares represented by American Depositary Shares or pre-funded warrants. The Common Warrants were originally exercisable for 90 days from the closing date of the private placements, which closing date was July 7, 2025.

The Common Warrants may be exercised for (i) Warrant Shares, at an exercise price equal to $14.00 for each Common Warrant or (ii) Pre-Funded Warrants, at an exercise price equal to $14.00 minus €0.10 for each Common Warrant. The exercise prices reflect the current ADS ratio of one ADS representing 100 ordinary shares.

On October 1, 2025, the Company extended the expiration date of the Common Warrants to December 31, 2025. Except for the Expiration Date Extension, all other terms and conditions of the Common Warrants remain unchanged.
