In the 2014 fourth quarter and year-end earnings press release of Axalta Coating Systems Ltd. (“Axalta”) issued on March 10, 2015, Axalta provided earnings guidance for the full year 2015, including a range of expected Adjusted EBITDA of $860 to $900 million. During the associated earnings conference call on March 11, 2015, Axalta provided additional insight around the anticipated timing of net sales and Adjusted EBITDA for the first quarter and remainder of 2015. In particular, Axalta noted several factors that would impact the first quarter of 2015. These factors included: (1) negative foreign currency impacts, with the first quarter of 2015 likely seeing the largest impact due to a stronger U.S. Dollar in the first quarter of 2015 relative to the first quarter of 2014; (2) certain OEM customer plants returning to full production schedules following their annual year-end slowdowns later in the first quarter of 2015 compared to the first quarter of 2014; (3) the impact of new light vehicle business coming on-line in the second half of 2015; (4) lower refinish product demand in the first quarter 2015 attributable to a relatively mild winter in North America and Europe; and (5) the impact of pre-start up activities related to Axalta’s new plant capacity at its Jiading, China facility. Axalta confirms its full year 2015 Adjusted EBITDA guidance of $860 to $900 million and further clarifies that such guidance incorporates first quarter Adjusted EBITDA of 18% to 20% of the full year Adjusted EBITDA range.

The information furnished with this Current Report 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.
