DEREGISTRATION OF SECURITIES

These Post-Effective Amendments (the “Post-Effective Amendments”) filed by Kraton Corporation, a Delaware corporation (the “Registrant”), deregister any and all shares of the Registrant’s common stock, $0.01 par value per share (the “Shares”), remaining unissued, and any other securities issuable by the Registrant, under the following Registration Statements on Form S-8, in each case as amended by any post-effective amendments thereto (each, a “Registration Statement”, and collectively, the “Registration Statements”) filed by the Registrant with the U.S. Securities and Exchange Commission (the “SEC”):

in each case, plus such indeterminate number of Shares as may have been issuable to prevent dilution resulting from one or more stock splits, stock dividends, or similar transactions in accordance with Rule 416(a) of the Securities Act of 1933, as amended (the “Securities Act”), and the terms of the applicable Registrant plan.

On March 15, 2022, pursuant to its previously announced Agreement and Plan of Merger, dated as of September 27, 2021 by and between DL Chemical Co., Ltd. (“Parent”), DLC US Holdings, Inc., DLC US, Inc. (“Merger Subsidiary”), and Registrant, Merger Subsidiary merged with and into the Registrant with the Registrant surviving the merger as an indirect and wholly-owned subsidiary of Parent (the “Merger”).

In addition, on March 15, 2022, The New York Stock Exchange (the “NYSE”) filed a Form 25 to report the delisting of the Shares from the NYSE and to deregister the Shares under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Registrant intends to file a Form 15 with the SEC, requesting termination of registration under Section 12(g) of the Exchange Act and the suspension of reporting obligations under Sections 13 and 15(d) of the Exchange Act, approximately 10 calendar days from the date hereof.

In connection with the closing of the Merger, the Registrant has terminated any and all offerings of its securities pursuant to the Registration Statements. Accordingly, the Registrant hereby terminates the effectiveness of each Registration Statement and, in accordance with the undertakings made by the Registrant in each of the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities that remain unsold at the termination of the offerings, the Registrant hereby removes from registration all Shares that were registered but unsold or otherwise unissued under the Registration Statements as of the date hereof.
