On the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, no par value (“SpartanNash common stock”), issued and outstanding immediately prior to the Effective Time (excluding SpartanNash common stock held by Parent or Merger Sub, in each case, immediately prior to the Effective Time) and all rights in respect thereof, by virtue of the Merger, was converted into the right to receive $26.90 in cash, without interest (the “Merger Consideration”), subject to any applicable withholding taxes.

In addition, pursuant to the Merger Agreement, at the Effective Time, (i) each outstanding SpartanNash equity-based award granted prior to the date of the Merger Agreement or to a non-employee director vested (with any awards subject to performance-based vesting conditions vesting to the extent set forth in the Merger Agreement and SpartanNash’s confidential disclosure letter) and was canceled and converted into the right to receive an amount in cash equal to the Merger Consideration (and any accrued but unpaid dividends or dividend equivalents) for each share of SpartanNash common stock subject to such equity-based award immediately prior to the Effective Time, with the number of shares of SpartanNash common stock determined based on the greater of the target and actual performance level for any award subject to performance-based vesting conditions, as determined by the Compensation Committee of the SpartanNash board of directors (the “Board”), (ii) any remaining unvested portion of any SpartanNash equity-based award granted prior to the date of the Merger Agreement that was subject to performance-based vesting conditions that did not vest as described in clause (i) was canceled and converted into the right to receive a cash-based award equal to the Merger Consideration (and any accrued but unpaid dividends or dividend equivalents) in respect of each share of SpartanNash common stock subject to such SpartanNash equity-based award immediately prior to the Effective Time (determined based on the greater of the target and actual performance level, as determined by the Compensation Committee of the Board), which cash-based award will vest and be payable on the last day of the applicable performance period, subject to the holder’s continued service with C&S and its affiliates through such date (or an earlier termination without cause, in which case any portion of the award that would vest in the next 12 months will accelerate and vest upon such termination), and (iii) each SpartanNash equity-based award not covered by clause (i) or (ii) vested as to one-sixth of the award and was canceled and converted into the right to receive an amount in cash equal to the Merger Consideration (and any accrued but unpaid dividends or dividend equivalents) in respect of each share of SpartanNash common stock subject to such award, and the remaining unvested portion was canceled and converted into the right to receive a cash-based award equal to the Merger Consideration (and any accrued but unpaid dividends or dividend equivalents) in respect of each share of SpartanNash common stock subject to such SpartanNash equity-based award immediately prior to the Effective Time, which cash-based award will, subject to the holder’s continued service with C&S and its affiliates through the applicable vesting dates, vest and be payable in accordance with the existing vesting schedule and other terms and conditions of such equity-based awards granted by the Company from which such cash award was converted (other than performance-based vesting conditions).
