Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers.

Pursuant to the bylaws of Advanced Emissions Solutions, Inc. (the “Company”), on February 27, 2019 the Board of Directors of the Company (the “Board”) voted to increase the size of the Board from five directors to seven directors and appointed Brian Leen to the Board to fill one of the resulting vacancies effective February 27, 2019. Further, Mr. Leen will serve as chair of a new committee, the Activated Carbon Committee, which was created to evaluate adjacent market growth opportunities for the activated carbon business. Mr. Leen will stand for election by the Company's stockholders at the Company's Annual Meeting of Stockholders in June 2019. The Company has initiated a search for a new director to fill the remaining vacancy.

Mr. Leen served as President and Chief Executive Officer of ADA Carbon Solutions, LLC (“Carbon Solutions”) until December 7, 2018, on which date the Company acquired Carbon Solutions (the "Carbon Solutions Acquisition"). Mr. Leen is now the President and Chief Executive Officer of Gopher Resource, LLC, a lead battery recycler. Mr. Leen has over 25 years of experience in the specialty chemicals and materials business. Prior to joining Carbon Solutions in 2010, he was President of the North American printing ink operations for Sun Chemical Corporation.

During the Company's planning for the integration of Carbon Solutions, some of the management of the Company discussed with Mr. Leen potential ways he could assist the Company in its growth strategy for the carbon business, including a focus on adjacent industries. Following the closing of the Carbon Solutions Acquisition, Mr. Leen met with members of the Nominating and Governance Committee of the Board (the “Nominating Committee”) and other directors. The Nominating Committee reviewed Mr. Leen’s background, qualifications, and independence in connection with the Company’s strategy and nominated him to the Board for appointment as a director.

In connection with the Carbon Solutions Acquisition, Mr. Leen’s position with Carbon Solutions was eliminated. Mr. Leen and the Company entered into a Release of Claims and Separation Agreement (the "Separation Agreement"), pursuant to which the Company agreed to pay him $2.2 million in compensation (the "Separation Payment"), which included previously agreed to retention bonuses plus a year of severance pay in the form of salary and bonuses, over the 52 weeks following the effective date of this Separation Agreement.

As a non-employee director, Mr. Leen will receive the compensation offered to all the Company’s non-employee directors for services on the Board, as disclosed in the Company’s definitive proxy statement on Schedule 14A, to be filed by the Company with the Securities and Exchange Commission within 120 days after December 31, 2018.

The Centers for Medicare & Medicaid Services (CMS) is the federal agency that oversees the Medicare program. Many Medicare beneficiaries have other insurance in addition to their Medicare benefits. Sometimes, Medicare is supposed to pay after the other insurance. However, if certain other insurance delays payment, Medicare may make a "conditional payment" so as not to inconvenience the beneficiary, andrecover after the other insurance pays.

Section 111 of the Medicare, Medicaid and SCHIP Extension Act of 2007 (MMSEA), a new federal law that became effective January 1, 2009, requires that liability insurers (including self­ insurers), no-fault insurers, and workers' compensation plans report specific information about Medicare beneficiaries who have other insurance coverage. The reporting is to assist CMS and other insurance plans to properly coordinate payment of benefits among plans so that your claims are paid promptly and correctly.
