By virtue of this relationship, Mr. Halpern may be deemed to share beneficial ownership of the securities held of record by the Trust. The number of shares of Common Stock owned by the Reporting Person reflects Ernexa Therapeutics Inc.'s (the "Issuer") 1-for-15 reverse stock split of its outstanding shares of common stock, par value $0.005 per share (the "Common Stock") that was effected on June 10, 2025 and the Issuer's 1-for-25 reverse stock split of its outstanding shares of Common Stock that was effected on May 4, 2026 (collectively, the "Reverse Stock Splits"), each as reported.

Row 11 is calculated based on an aggregate of 1,186,639 shares of Common Stock of the Issuer outstanding, which is calculated by adding (i) 1,166,333 shares of Common Stock of the Issuer outstanding as of May 8, 2026, as reported in the Issuer's Quarterly Report on Form 10-Q filed with the SEC on May 11, 2026, and (ii) 20,306 shares of Common Stock of the Issuer issuable to the Reporting Person upon exercise of the Warrants within 60 days, and which, for (ii), is deemed outstanding pursuant to Rule 13d-3(d)(1)(i).
