Paris — September 4, 2025 — Sequans Communications S.A. (NYSE: SQNS) (“Sequans” or the “Company”), a pioneer in adopting Bitcoin as its primary treasury reserve asset and a leading provider of cellular IoT semiconductor solutions, today announced that its Board of Director has approved a plan to change the ratio of its American Depositary Shares ("ADSs") to its ordinary shares (the "ADS Ratio"), from the current ratio of one (1) ADS to ten (10) ordinary shares to a new ratio of one (1) ADS to one hundred (100) ordinary shares. Sequans’ ordinary shares are not affected by the change.

The new ADS to ordinary share ratio of 1 for 100 will be effective prior to the commencement of trading on the New York Stock Exchange on September 17, 2025.

The primary objectives of the ADS ratio change are:

1.Practicality and Convenience – Following the capital increase of July 2025, which significantly increased the number of outstanding shares, this change will reduce the number of ADS outstanding for operational efficiency.

2.Enhanced Market Appeal – The higher per-ADS price is expected to make Sequans’s ADS more attractive to a broader range of institutional investors, including funds that have minimum price thresholds for investment.

3.Regulatory Compliance and Strategic Flexibility – This adjustment will help ensure continued compliance with NYSE listing requirements and provide resilience against potential market volatility, particularly as the Company continues to execute its Bitcoin treasury strategy.

For the Company's ADS holders, the ADS ratio change will have the same effect as a one-for-ten reverse ADS split. No fractional new ADSs will be issued in connection with the ADS ratio change. Holders who would otherwise receive fractional ADSs will receive a cash payment in lieu of such fractional ADSs. The cash in lieu rate will be set when the depositary sells the ADSs that would otherwise have been issued as fractional ADSs in one or more market trades.

Effective September 17, 2025, Holders in the Direct Registration System and in DTC will have their ADSs automatically exchanged and need not take any action. Beneficial holders may contact their bank, broker or nominee for more information. ADS holders with ADSs held in certificate form will be required to exchange their certificates for new book-entry ADSs at a rate of 10 old ADSs for 1 new ADS.

The Company’s ADSs will continue to trade on the New York Stock Exchange (“NYSE”) under the ticker symbol “SQNS”.

As a result of the ADS ratio change, the trading price per ADS is expected to increase proportionally, although the Company can give no assurance that the trading price per ADS after the ratio change will be equal to or greater than ten times the trading price per ADS before the change.
