Bank of America's threshold crossings in ABIVAX

Bank of America Corporation recently crossed two ownership thresholds in ABIVAX. On October 5, 2026, the company crossed the 5% ownership threshold, holding 4,754,159 shares, representing 5.45% of the share capital and 5.37% of the voting rights. This increase was due to market acquisitions and the issuance of shares by fungibility.

On October 6, 2026, Bank of America reversed the trend, crossing below the 5% threshold and reducing its stake to 4,196,156 shares, representing 4.81% of the share capital and 4.74% of the voting rights. This resulted from market sales and a decrease in shares held by fungibility.

Merrill Lynch International and BofA Securities, Inc., subsidiaries of Bank of America, hold option contracts and swaps related to ABIVAX, influencing these threshold movements.
