EXPLANATORY STATEMENT — DEREGISTRATION OF UNSOLD SECURITIES

This Post-Effective Amendment (this “Post-Effective Amendment”) relates to the following Registration Statements of Soliton, Inc. (the “Company”) on Form S-1 (collectively, the “Registration Statements”):

On December 16, 2021 (the “Effective Time”), the Company completed the merger contemplated by the Agreement and Plan of Merger (the “Merger Agreement”), dated as of May 8, 2021, among the Company, AbbVie Inc. (“AbbVie”) and Scout Merger Sub, Inc., a wholly owned subsidiary of AbbVie (“Merger Sub”). Pursuant to the Merger Agreement, Merger Sub was merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of AbbVie. Upon consummation of the Merger, at the Effective Time, each share of Common Stock of the Company issued and outstanding immediately prior to the Effective Time (other than shares owned by the Company, AbbVie, or Merger Sub (which were cancelled) and shares with respect to which appraisal rights were properly exercised and not withdrawn under Delaware law) was automatically converted into the right to receive $22.60 in cash, without interest.

As a result of the Merger, the Company has terminated any and all offerings of its securities pursuant to the Registration Statements. Accordingly, the Company hereby terminates the effectiveness of the Registration Statements and, in accordance with the undertakings made by the Company in the Registration Statements to remove from registration, by means of a post-effective amendment, any securities that had been registered for issuance but remain unsold at the termination of the offering, removes from registration any and all securities of the Company registered but unsold under the Registration Statements as of the date hereof.
