The reporting persons disclose beneficial ownership of 91,537 Bluejay Diagnostics shares, or 4.99% of the common stock. This consists of 71,243 common shares plus 20,294 shares issuable from one warrant, calculated against 1,814,133 shares outstanding and those warrant shares.

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 warrants to buy Bluejay Diagnostics (BJDX) stock does Intracoastal hold?

Intracoastal holds three warrants, including “Intracoastal Warrant 1” for a larger number of shares. The beneficial total includes 20,294 shares from Warrant 1, while 729,706 additional Warrant 1 shares and small positions from two other warrants are excluded due to blocker provisions.

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.

Are the Bluejay Diagnostics (BJDX) shares held to influence control of the company?

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.
