[Form 4] Lightwave Logic, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Lightwave Logic, Inc. (LWLG) – Form 4 insider activity

CFO/COO and Director James S. Marcelli disclosed two same-day transactions dated 17 June 2025 that altered his equity position:

• Option exercise (Code M): Marcelli exercised 1,150,000 employee stock options at an exercise price of $0.70, temporarily increasing his common-stock holdings to 1,439,700 shares.
• Share withholding (Code F): The issuer withheld 800,762 shares (valued at $1.27 per share) to cover the option-exercise price and associated tax obligations. This reduced Marcelli’s directly held shares to 638,938.

Residual positions:

• Common stock: 638,938 shares held directly after the transactions.
• Derivatives: 792,336 stock options still outstanding following the partial exercise; the exercised tranche originated from a 1 July 2015 grant.

This filing reflects a cashless/net-settled option exercise rather than an open-market sale. The net result is an incremental issuance of 349,238 shares to the executive, signalling retention of a meaningful equity stake while satisfying tax and exercise obligations internally. No new information on operational or financial performance is provided.

Insights

Securities Analyst

TL;DR: Routine net-settled option exercise; minimal market impact, shows insider retains sizeable position.

The Form 4 indicates CFO/COO Marcelli exercised 1.15 million options at $0.70 and surrendered 800,762 shares to cover costs, ending with 638,938 shares and 792,336 unexercised options. Because the disposition was issuer-withheld (Code F), no shares hit the open market, limiting supply effects. His continued ownership supports alignment with shareholders, but the transaction does not imply new valuation-relevant information. Overall, I view the disclosure as neutral for LWLG shares.
