Election of New Director. The board of directors (the “Board”) of IDEXX Laboratories, Inc. (the “Company”) elected Bruce L. Claflin as an independent Class I Director and member of its audit committee and nominating and governance committee on July 14, 2015. To accommodate Mr. Claflin’s election as a Class I Director, the Board increased the number of Directors constituting the Board from eight to nine and the number of Class I Directors from two to three. The number of Directors constituting the Board and the number of Class I Directors had been previously reduced at a meeting of the Board immediately following the Company’s 2015 annual meeting of stockholders (the “2015 Annual Meeting”) from nine to eight and from three to two, respectively. These reductions were made by the Board in connection with the retirement of Robert J. Murray as a Class III Director at the 2015 Annual Meeting pursuant to the mandatory retirement provisions of the Company’s Corporate Governance Guidelines and the Board’s subsequent reassignment of Barry C. Johnson, who had been re-elected as a Class I Director at the 2015 Annual Meeting, from a Class I to Class III Director to fill the vacancy created by Mr. Murray’s retirement.

It is expected that Mr. Claflin will stand for election by stockholders as a Class I Director at the 2018 annual meeting of stockholders, with a three-year term expiring in 2021.

Mr. Claflin will receive the same compensation as is paid to other nonemployee Directors of the Company as described in the section entitled “Corporate Governance – Director Compensation” in the Company’s Proxy Statement filed with the Securities and Exchange Commission on March 25, 2015, which description is incorporated herein by reference. The cash fee to be paid to Mr. Claflin for the third quarter of 2015 will be prorated to reflect his election on July 14, 2015. Annual deferred stock unit and stock option grants were made to Directors on May 6, 2015, the date of the 2015 Annual Meeting. Since Mr. Claflin was not serving as a Director at that time, such grants will be made to Mr. Claflin on September 1, 2015, and the award values will be prorated to reflect the portion of the year during which he will serve on the Board, specifically from his election on July 14, 2015 until the Company’s 2016 annual meeting of stockholders.

On July 14, 2015, the Company issued a press release regarding Mr. Claflin’s election to the Board. A copy of the press release is furnished as Exhibit 99.1 to this Form 8-K.

The following exhibit relating to Item 5.02 shall be deemed to be furnished, and not filed.
