Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On March 16, 2015, Axalta Coating Systems Ltd. (the “Company”) filed a Registration Statement on Form S-1 (the “Registration Statement”) relating to the potential sale by certain selling shareholders of 35,000,000 common shares. The Registration Statement contained certain information not previously disclosed by the Company, and the Company is filing this Current Report on Form 8-K (this “Current Report”) to present certain updated information relating to the Company’s operations, industry, competitive strengths and business strategy (the “Summary Information”) and to present its Compensation Discussion and Analysis information for the fiscal year ended December 31, 2014, to the extent such Compensation Discussion and Analysis information is determinable as of the date hereof. Exhibit 99.1, which is incorporated herein by reference, contains such Summary Information and Compensation Discussion and Analysis information.

The Company’s proxy statement for the 2015 Annual General Meeting will include the Compensation Discussion and Analysis information, in its entirety, along with the report of the Company’s Compensation Committee. The Company’s shareholders are urged to read the proxy statement for the 2015 Annual General Meeting when it is available because it will include additional compensation information. In particular, the proxy statement for the 2015 Annual General Meeting will include shareholder action items required under the Dodd-Frank Wall Street Reform and Consumer Protection Act relating to shareholder approval of executive compensation.

The Registration Statement has been filed with the SEC but has not yet become effective. This Current Report shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of the securities pertaining to the Registration Statement in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

The information furnished with this Current Report, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any other filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such a filing.

Cautionary Statement Concerning Forward-Looking Statements

This Current Report may contain certain forward-looking statements regarding the Company and its subsidiaries. All of these statements are based on management’s expectations as well as estimates and assumptions prepared by management that, although they believe to be reasonable, are inherently uncertain. These statements involve risks and uncertainties, including, but not limited to, economic, competitive, governmental and technological factors outside of the Company’s control that may cause its business, industry, strategy, financing activities or actual results to differ materially. The Company undertakes no obligation to update or revise any of the forward-looking statements contained herein, whether as a result of new information, future events or otherwise.
