Companhia Siderúrgica Nacional (“CSN” or “Company”) (B3: CSNA3; NYSE: SID), in compliance with applicable regulations, hereby informs its shareholders and the market that, on August 13, 2026, it received a non-compliance notification letter (the “Notice”) from the New York Stock Exchange (the “NYSE”). The Notice states that the Company is not in compliance with the NYSE’s continued listing standard set forth in Section 802.01C of the NYSE Listed Company Manual, as the average closing price of the Company’s American Depositary Shares (the “ADSs”) was less than $1.00 per ADS over a consecutive 30-trading-day period. Pursuant to the NYSE rules, the Company has a period of six months from the receipt of the notice to regain compliance with the minimum share price requirement (the “Cure Period”). The Notice does not result in the immediate delisting of the Company’s ADSs from the NYSE. The Company has notified the NYSE of its intention to cure.

The Company is actively evaluating all available cure alternatives to regain compliance with the NYSE minimum share price requirement within the Cure Period. Since the receipt of the NYSE correspondence, Company’s ADSs have experienced a price appreciation, currently trading above the US$ 1.00 minimum threshold.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
