Explanatory Note

On January 15, 2026, Sequans Communications S.A. (“Sequans” or “the Company”) announced that it regained compliance with the New York Stock Exchange (NYSE) continued listing standards.

On June 5, 2025, the NYSE notified Sequans of its non-compliance due to the Company’s average global market capitalization falling below $50 million over a consecutive 30-trading-day period, while at the same time, its stockholders’ equity was below $50 million.

To address these deficiencies and restore compliance, Sequans took corrective actions, including primarily increasing its stockholders’ equity and market capitalization following a $195 million equity private placement that closed July 7, 2025.

Following these measures, the NYSE has confirmed that Sequans is now fully compliant with all applicable listing requirements.
