Rhea-AI Filing Summary

Equity awards were adjusted per the agreement: unvested RSUs were converted into cash-based awards that retain the original vesting terms with double-trigger acceleration upon certain terminations, and PSUs were converted into cash awards based on the greater of target or actual performance, payable on the original performance period end date. The holdings included 26,758 unvested RSUs prior to these adjustments. The filing also notes prior sales from 2020–2022 are reflected here.

Governance & Equity Compensation Analyst

Form 4 reflects merger cash-out at $17.12 and award conversions.

The filing documents completion mechanics of Potbelly’s merger with RaceTrac, Inc., where each common share converted into a cash right of $17.12. The officer’s reported transactions on 10/23/2025 align with standard cash-out treatment when a merger closes and equity is cancelled.

Unvested RSUs converted to cash-based awards that keep existing vesting, with double-trigger acceleration upon certain terminations post-closing. PSUs converted to cash using the greater of target or actual performance, payable at the original performance period end. These terms define payout timing and conditions but do not change merger consideration.

The filing also states that certain historical sales from 2020–2022 are reflected. Overall, this is administrative and consistent with merger close-out and equity award treatment.

Explanation of Responses:

1. Pursuant to the Agreement and Plan of Merger, dated as of September 9, 2025 (the 'Merger Agreement'), by and among the Issuer, RaceTrac, Inc. ('Parent'), and Hero Sub Inc. ('Merger Sub'), Merger Sub merged with and into the Issuer (the 'Merger'), with the Issuer surviving the Merger as a wholly owned subsidiary of Parent. At the effective time of the Merger (the 'Effective Time'), upon the terms and subject to the conditions set forth in the Merger Agreement, each share of common stock, par value $0.01 per share ('Common Stock'), of the Issuer that was issued and outstanding as of immediately prior to the Effective Time was automatically cancelled, extinguished and converted into the right to receive $17.12 per share in cash, without interest thereon (but subject to applicable withholding) (the 'Per Share Price').

2. Includes 26,758 unvested restricted stock units ("RSUs"). Pursuant to the terms of the Merger Agreement, at the Effective Time, (A) each RSU that is outstanding and vested (but not yet settled) as of immediately prior to the Effective Time, taking into account any acceleration of vesting of any RSU that occurs upon the Effective Time (each, a "Vested RSU"), was automatically cancelled and converted into the right to receive an amount in cash, without interest thereon (but subject to applicable withholding), equal to the product obtained by multiplying (i) the Per Share Price by (ii) the total number of shares of Common Stock subject to such RSU and (B) each outstanding RSU that was not a Vested RSU (each, an "Unvested RSU") was automatically cancelled and substituted into the contingent right to receive an aggregate amount (without interest) in cash (a "Substituted RSU Cash Award") equal to the product obtained by multiplying (i) the Per Share Price by (ii) the total number of shares

3. (continued from footnote 2) of Common Stock subject to such RSU. Each such Substituted RSU Cash Award will continue to have, and will be subject to, the same vesting terms and conditions as applied to the corresponding Unvested RSU immediately prior to the Effective Time, except that each such Substituted RSU Cash Award will be afforded "double-trigger" accelerated vesting upon the applicable holder's termination without cause or resignation for good reason, in each case, that occurs during a post-closing period.

4. The sales of 4,783 shares of Common Stock on December 10, 2020 and 12,500 shares of Common Stock on January 18, 2022 were inadvertently not reported, and the reported sale of 6,933 shares of Common Stock on September 23, 2021 to cover the tax liability upon vesting of RSUs was inadvertently not reflected in subsequent Form 4 filings. These sales are reflected here.

5. Pursuant to the terms of the Merger Agreement, at the Effective Time, each performance-based restricted stock unit ("PSU") that was outstanding and unvested as of immediately prior to the Effective Time, was automatically cancelled and substituted into and became the contingent right to receive an amount in cash, without interest thereon (but subject to applicable withholding) (a "Substituted PSU Cash Award"), equal to the product obtained by multiplying (i) the Per Share Price by (ii) the total number of shares of Common Stock subject to such PSU, with the achievement of the performance-based vesting metrics applicable to each PSU based on the greater of target or actual achievement of the applicable performance metrics. Each such Substituted PSU Cash Award will be payable on the last day of the performance period that applied to the corresponding PSUs immediately prior to the Effective Time (such date, the "Vesting Date"), subject to the applicable holder's continued employment or

6. (continued from footnote 5) service through the Vesting Date, except that each such Substituted PSU Cash Award will be afforded "double-trigger" accelerated vesting upon such applicable holder's termination without cause or resignation for good reason, in each case, that occurs during a post-closing period.
