(d)

On July 1, 2015, the Board of Directors (the “Board”) of Knowles Corporation (the “Company”), upon recommendation of the Governance and Nominating Committee of the Board, appointed Dr. Hermann Eul, Corporate Vice President and General Manager at Intel Corporation, as a director, increasing the size of the Board from eight members to nine. Dr. Eul will serve as a Class III director and will hold office until the Company’s 2016 Annual Meeting of Stockholders, or until his successor is duly elected and qualified. Upon recommendation of the Governance and Nominating Committee of the Board, Dr. Eul was also appointed to serve on the Compensation and the Governance and Nominating Committees of the Board.

The Board has determined that Dr. Eul meets the standards of independence under the Company’s Standards for Director Independence, as well as applicable rules of the NYSE, the SEC and the Securities Exchange Act of 1934. There is no arrangement or understanding between Dr. Eul and any other person pursuant to which he was selected as a director. There are no transactions since the beginning of the Company’s last fiscal year, or any currently proposed transactions, with the Company to which Dr. Eul was or is to be a party, in which Dr. Eul, or any member of his immediate family, has a direct or indirect material interest.

Dr. Eul will receive the same compensation as the Company’s other non-employee directors: a one-time award of unrestricted shares of the Company’s common stock with a grant date fair value equal to $100,000 (payable in full on July 30, 2015) and an annual retainer of $215,000, payable $65,000 in cash and $150,000 in restricted stock units (in each case pro-rated for 2015).

A copy of the press release announcing the appointment of Dr. Eul to the Board is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
