Porter Stuart D reported acquisition or exercise transactions in this Form 4 filing.
LIXTE BIOTECHNOLOGY HOLDINGS, INC. director Stuart D. Porter reported receiving an equity grant of 25,000 shares of common stock in the form of restricted share units. The grant was made at a stated price of $0.00 per share, reflecting stock-based compensation rather than a market purchase.
The 25,000 RSUs were granted under the company’s 2020 Stock Incentive Plan. Each RSU represents a contingent right to receive one share of common stock upon vesting, subject to continued service. The RSUs vest 25% on May 29, 2026, and 25% on the last date of each subsequent calendar quarter until fully vested. Following this grant, Porter directly holds 25,000 shares.
Lixte Biotechnology CEO Geordan Garrett Pursglove restructured his equity compensation on April 15, 2026. He agreed to cancel 350,000 options to purchase common stock with a $2.83 exercise price that were scheduled to expire on July 3, 2030, returning them to the company.
In exchange, he received 350,000 shares of common stock as a grant or award tied to 350,000 restricted share units under the 2020 Stock Incentive Plan. These RSUs vest immediately upon grant, so he now directly holds 350,000 common shares after the transaction. The filing shows no open‑market buying or selling; it is an issuer disposition of options paired with a compensatory stock award.
LIXTE BIOTECHNOLOGY HOLDINGS, INC. Chief Financial Officer Peter Stazzone restructured his equity compensation on April 15, 2026. He agreed to cancel 50,000 stock options with a $4.45 exercise price in exchange for 50,000 restricted stock units granted the same day.
Each RSU represents a contingent right to receive one share of common stock, and all 50,000 RSUs vested immediately upon grant, leaving him with 50,000 shares of common stock held directly after the transactions. No open‑market buying or selling occurred; these were compensation-related adjustments between the executive and the company.
LIXTE BIOTECHNOLOGY HOLDINGS, INC. director Felix Lourdes entered into a Stock Option Cancellation Agreement on April 15, 2026. The company canceled 25,000 stock options with a $4.05 exercise price that had been granted on December 24, 2025 and, in exchange, granted 25,000 restricted share units (RSUs).
Each RSU represents a right to receive one share of common stock upon vesting, and all 25,000 RSUs vested immediately on the grant date. Following these compensation-related transactions, Lourdes directly holds 25,000 shares of common stock, with no remaining options from the canceled grant.
Director Jason David Sawyer reported a compensation-related change in his equity awards in LIXTE BIOTECHNOLOGY HOLDINGS, INC. On April 15, 2026, he agreed with the company to cancel 25,000 options to purchase common stock with a $3.59 exercise price, which otherwise would have vested over time. In exchange, he received 25,000 restricted share units (RSUs), each representing a contingent right to one share of common stock. The RSUs were granted under the company’s 2020 Stock Incentive Plan and vested immediately upon grant, resulting in 25,000 shares of common stock held directly after the transactions. This sequence is a restructuring of equity compensation rather than an open-market buy or sell.
LIXTE BIOTECHNOLOGY HOLDINGS, INC. director Michael Andrew Holloway restructured his equity compensation on April 15, 2026. He disposed of options to purchase 25,000 shares of common stock back to the company and, in exchange, received 25,000 restricted share units (RSUs).
Each RSU represents a right to receive one share of common stock, and all 25,000 RSUs vested immediately upon grant, subject to continued service conditions in the plan documents. Following these transactions, Holloway directly holds 25,000 shares of common stock, reflecting this grant-and-cancel structure rather than an open-market trade.
LIXTE BIOTECHNOLOGY HOLDINGS, INC. director Guy Warren Primus exchanged equity awards on April 15, 2026.
