Rhea-AI Filing Summary

Lyra Therapeutics insider amendment corrects previously reported stock-option activity and clarifies current holdings. The reporting person, Maria Palasis, was originally granted performance stock options totaling 11,000 shares (stated as 550,000 pre-split) on 03/21/2024, but those PSOs were forfeited for no value on 02/14/2025. An earlier Form 4 filed on 10/03/2025 mistakenly reported the acquisition of 3,667 PSOs; this amended Form 4/A, filed on 10/08/2025, reverses that entry and states the Reporting Person currently does not beneficially own any of the PSOs granted on 03/21/2024. The filing was signed by an attorney-in-fact and notes the transaction price of the related employee stock option as $303.5 with an expiration of 03/20/2034.

Positive

  • Corrective filing was submitted to reverse an erroneous acquisition report (Form 4/A filed 10/08/2025)
  • Reporting person holds no PSOs from the March 21, 2024 grant after forfeiture on 02/14/2025, removing related potential dilution

Negative

  • Erroneous Form 4 filed on 10/03/2025 initially reported acquisition of 3,667 PSOs, indicating an administrative or reporting error
  • PSOs forfeited for no value on 02/14/2025, meaning the granted compensation did not vest into valuable equity

Insights

TL;DR: A corrective filing removes previously reported insider option holdings and confirms forfeiture of PSOs.

The reporting clarifies that the 11,000-share performance stock option grant from 03/21/2024 was entirely forfeited on 02/14/2025, leaving the reporting person with zero beneficial ownership of those PSOs. The amendment corrects an erroneous acquisition report dated 10/03/2025 that had listed 3,667 PSOs.

This reduces short-term insider ownership disclosure complexity and eliminates the previously reported option count as a near-term factor for shareholders; governance watchers should note the administrative error and the corrective filing dated 10/08/2025 as an item of record over the next quarter.

TL;DR: The PSOs were forfeited for no value and related option economics are no longer outstanding.

The original PSO grant provided up to 11,000 shares (pre-split equivalent 550,000) with an indicated exercise/option pricing reference of $303.5 and an expiration of 03/20/2034. The filing states the PSOs were forfeited on 02/14/2025, which removes potential dilution tied to this award.

Watch for future disclosures if new awards are granted or if similar administrative errors recur; any new grants would be material to dilution metrics within the next 12 months.

Explanation of Responses:
1. On March 21, 2024, the Reporting Person was granted a performance stock option ("PSO") for an aggregate of up to 11,000 shares of common stock (or 550,000 shares on a pre-split basis) under the Issuer's 2020 Incentive Award Plan. On February 14, 2025, the PSOs were forfeited in their entirety by the Reporting Person for no value.
Remarks:
On October 3, 2025, a Form 4 was inadvertently filed reporting the acquisition of 3,667 PSOs by the Reporting Person. In fact, the Reporting Person did not acquire the PSOs and this Form 4/A is being filed to correct the erroneously reported acquisition. As of the date hereof, the Reporting Person does not beneficially own any of the PSOs granted on March 21, 2024.
