On December 19, 2025, Nicolet Bankshares, Inc. ("Nicolet") and MidWest*One* Financial Group, Inc. ("MidWest*One*") filed with the Securities and Exchange Commission ("SEC") their joint proxy statement-prospectus in connection with the contemplated merger of Nicolet and MidWest*One.* After it was filed, Nicolet and MidWest*One* identified an error in the Golden Parachute Compensation table for MidWest*One* that appears on page 74 of the joint proxy statement-prospectus. Specifically, although the amounts in the first three columns of the table are accurate, the fourth column ("Total") did not accurately reflect the total of the amounts set forth in the other three columns. The corrected "Merger-Related Compensation for MidWestOne Named Executive Officers" is as follows:

*Merger-Related Compensation for MidWestOne Named Executive Officers*

The information below is intended to comply with Item 402(t) of Regulation S-K, which requires the disclosure of information regarding certain compensation and benefits related to the merger payable to MidWest*One*'s named executive officers, sometimes referred to as "golden parachute" compensation. The merger-related compensation shown in this table and described in the footnotes to the table is the subject of the non-binding advisory vote of MidWest*One*'s shareholders, as described above in "— Proposal 2 — MidWest*One* Merger-Related Compensation Proposal." The figures in the table are estimates based on current compensation levels, each named executive officer's existing compensation arrangements with MidWest*One* and multiple assumptions that may or may not actually occur or be accurate on the relevant date, including the assumptions described below. The table does not include the value of benefits under the MidWest*One* Executive Deferred Compensation Plan in which the named executive officers are vested without regard to the occurrence of a change in control. For purposes of calculating such amounts, we have assumed

&nbsp;&nbsp;&nbsp;&nbsp;· February 13,
 2026, as the closing date of the merger (which is the assumed date solely for purposes of
 this merger-related compensation disclosure);

&nbsp;&nbsp;&nbsp;&nbsp;· a termination of each
 named executive officer's employment without cause (and not by reason of the executive
 officer's death or disability) or resignation for good reason under the applicable
 employment agreement, effective as of immediately following the effective time of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;· each named executive
 officer complies with all requirements necessary to receive all severance payments and benefits
 pursuant to his employment agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;· a price per share
 of $37.65, which is the average closing market price of MidWest *One* 's shares
 over the first five business days following the first public announcement of the merger on
 October 23, 2025.

For purposes of this discussion, "single trigger" refers to benefits that arise solely as a result of the completion of the merger and "double trigger" refers to benefits that require satisfaction of two conditions, which are the completion of the merger and a qualifying termination of the named executive officer's employment. Payments of double trigger benefits are contingent on the named executive officer signing and not revoking a release of claims in favor of MidWest*One* and satisfying certain other conditions. For additional details regarding the terms of the payments described below, see the discussion under the caption "— Interests of Certain Persons in the Merger" above.
