Rhea-AI Filing Summary

Explanation of Responses:

1. Represents vesting an award of performance-based restricted stock units ("RSUs") issued pursuant to the Company's 2018 Equity Incentive Plan. Each RSU represents the right to receive, at settlement, one share of common stock.

2. The reported disposition reflects shares withheld by the Company to cover required tax withholding obligations upon the vesting of the RSUs. The reporting person did not sell any shares.

3. The RSUs vested on the last day of the month upon satisfaction of the "Baby Shelf" performance condition described in the Reporting Person's Employment Agreement, which required that the Company's public float reach at least $75 million such that the Company would no longer be subject to the SEC's "baby shelf" limitations on Form S-3 eligibility. The satisfaction of this condition resulted in the vesting of 50% of the RSUs granted to the Reporting Person, subject to the Reporting Person's continued service.

Remarks:

This Form 4/A is being filed to amend the original Form 4 filed on November 4, 2025 which inadvertently did not report the withholding of 12,175 shares of common stock to cover tax withholding obligations upon the vesting of performance-based restricted stock units ("RSUs").
