Icahn, a citizen of the United States of America (“Icahn”, and together with Starfire and Merger Sub, the “Reporting Persons”), with respect to the shares of common stock, $0.01 par value (“Common Stock”), of Cadus Corporation, a Delaware corporation (the “Issuer”), is hereby amended to furnish the additional information set forth herein. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Schedule 13D.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended by adding the following:

On June 28, 2018, Issuer held a special meeting of its stockholders (the “Special Meeting”) to approve a proposal to adopt the previously disclosed Agreement and Plan of Merger (the “Merger Agreement”), by and among the Issuer, Merger Sub and Starfire. At the Special Meeting, the proposal to adopt the Merger Agreement was approved by the affirmative vote of both (i) the holders of a majority of the outstanding shares of Common Stock entitled to vote on the adoption of the Merger Agreement and (ii) the holders of a majority of the outstanding shares of Common Stock entitled to vote on the adoption of the Merger Agreement that were not beneficially owned by Starfire, Merger Sub or their affiliates. Later that day on June 28, 2018, pursuant to the terms of the Merger Agreement, the merger of Merger Sub with and into the Issuer, with the Issuer continuing as the surviving entity after the merger, was consummated (the “Merger”). As a result of the Merger, the Issuer is now a wholly-owned subsidiary of Parent.

As part of the Merger, each share of Common Stock issued and outstanding immediately prior to the effective time of the Merger was cancelled, and each such share of Common Stock (other than (i) shares that are owned by Parent, Merger Sub or any of their respective subsidiaries or affiliates (other than the Issuer or any of its management)), (ii) shares owned by the Issuer or the Issuer’s subsidiaries or (iii) shares held by any of the Issuer’s stockholders that have perfected and not effectively withdrawn or lost their appraisal rights under Delaware law) was converted into the right to receive $1.61 in cash, without interest, less any applicable withholding taxes.
