Who are the reporting persons in the Bluejay Diagnostics (BJDX) Schedule 13G/A?

The filing is made on behalf of Mitchell P. Kopin, Daniel B. Asher and Intracoastal Capital LLC. Kopin and Asher are U.S. individuals, while Intracoastal is a Delaware limited liability company that directly holds the common shares and warrants referenced.

How is the 4.99% ownership of Bluejay Diagnostics (BJDX) calculated?

The 4.99% figure is based on 1,814,133 Bluejay common shares outstanding plus 20,294 warrant shares. The 91,537 beneficially owned shares are divided by that total, resulting in ownership just under the 5% regulatory threshold referenced in the filing.

What is the 4.99% blocker affecting Bluejay Diagnostics (BJDX) warrants?

The warrants contain a 4.99% blocker that limits exercises if they would push ownership above 4.99%. This restriction applies to the holder, its affiliates and any coordinated group, preventing additional warrant exercises that would raise beneficial ownership beyond that threshold.

The reporting persons certify the securities were not acquired to change or influence control of Bluejay Diagnostics. They state the holdings are not part of any transaction intended to affect control, other than activities tied solely to a director nomination under the referenced rule.
