Submission of Matters to a Vote of Security Holders.

The 2017 Annual Meeting of Stockholders of Nanophase Technologies Corporation (the “Company”) was held on August 24, 2017. The following is a summary of the proposals submitted to the Company's stockholders, as described in the Company's definitive proxy statement filed on July 14, 2017, and final results of the voting on each matter.

In addition to Mr. Jankowski, Dr. Siegel and Mr. Tyler, James A. Henderson, James A. McClung, Ph.D., R. Janet Whitmore and George A. Vincent, III continued their terms of office as directors of the Company after the Annual Meeting. 

Furnished as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference is a copy of the slides that the Company intends to utilize in presentations to investors and other third parties. The Company is also making a copy of the attached slides available on the Company’s website, www.nanophase.com.

The slides attached as Exhibit 99.1 include non-GAAP financial measures that differ from financial measures calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). The Company believes that the presentation of results excluding certain items, such as non-cash equity compensation charges, provides meaningful supplemental information to both management and investors, facilitating the evaluation of performance across reporting periods. The Company uses these non-GAAP measures for internal planning and reporting purposes. These non-GAAP measures are not in accordance with, or an alternative for, GAAP and may be different from non-GAAP measures used by other companies. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net income prepared in accordance with GAAP. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measure are included in Exhibit 99.1.

The information in Item 7.01 of this Current Report on Form 8-K and Exhibit 99.1 attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing. By filing this Current Report on Form 8-K and furnishing this information, the Company makes no admission as to the materiality of any information in this report, including Exhibit 99.1. Any reference to the Company’s internet address shall not, under any circumstances, be deemed to incorporate the information available at, or accessible through, such internet address into this report.
