Ronald A. Bucchi, a director at Lightwave Logic, Inc. (NASDAQ: LWLG), reported the sale of 11,000 shares of the company's common stock on April 1, 2026, generating approximately $76,120. According to the Form 4 filed with the Securities and Exchange Commission, the shares were sold at a weighted average price of $6.92, with the individual trade prices ranging narrowly between $6.91 and $6.92.
The filing states the transaction was undertaken to satisfy tax withholding obligations tied to restricted stock units (RSUs) that vested on March 31, 2026. On that same date, Bucchi exercised 20,161 RSUs, which converted into common stock. The subsequent sale of 11,000 of those shares took place the following day.
After these transactions were completed, Bucchi's direct ownership in Lightwave Logic stands at 294,879 shares of common stock. In addition, he indirectly owns 3,000 shares through his spouse, as disclosed in the Form 4.
The timing of the sale coincides with a period of elevated share-price movement for Lightwave Logic. The company's stock has experienced a substantial year-over-year gain of 584% while also recording a short-term decline of 12.7% over the past week, figures that reflect significant volatility in the name.
Separately, Lightwave Logic reported financial results for the fourth quarter of 2025, noting a 147% increase in revenue compared with the same quarter a year earlier. The company attributed that revenue growth primarily to licensing and non-recurring engineering activities. Despite the revenue acceleration, Lightwave Logic remains in the pre-commercialization phase of its business.
Also disclosed by the company was a development agreement with Tower Semiconductor. Under this collaboration, Lightwave Logic will work to integrate its electro-optic polymer modulator technology into Tower's PH18 silicon photonics platform. The development effort is aimed at creating modulator reference designs targeting bandwidths of 110GHz and beyond, enabling design options for optical modulators intended for 400G per lane applications. Lightwave Logic characterized the Tower Semiconductor agreement as a strategic step in advancing its technology into silicon photonics environments.
The transactions involving Bucchi - the vesting and conversion of RSUs, the related sale to meet withholding obligations, and the updated ownership position - were detailed in the SEC Form 4 filing and mirror the company disclosures on recent operational progress and partnerships.
