On July 18, 2016, Superconductor Technologies Inc. (the “Company” or “we” or “our”) effected a one-for-fifteen (1-for-15) reverse stock split of our common stock, par value $0.001 (the “Reverse Stock Split”). The Company filed a Certificate of Amendment of its Restated Certificate of Incorporation, as amended (the “Restated Certificate of Incorporation”), with the Secretary of State of the State of Delaware, to effect the Reverse Stock Split.

As previously described in detail in our definitive proxy statement filed with the Securities and Exchange Commission on May 16, 2016, the Company held a Special Meeting of Stockholders on June 23, 2016 (the “Special Meeting”), at which meeting the stockholders approved amendment of our Restated Certificate of Incorporation to effect a reverse stock split of our common stock at a ratio in the range of not less than 1-for-2 and not more than 1-for-15. Our board of directors thereafter selected the 1-for-15 reverse stock split ratio and authorized the implementation of the Reverse Stock Split.

As a result of the Reverse Stock Split, every fifteen (15) shares of our pre-Reverse Stock Split common stock were combined and reclassified into one (1) share of our common stock. Our post-Reverse Stock Split common stock will begin trading on July 19, 2016 with a new CUSIP number of 867931 503. The Reverse Stock Split did not change our authorized number of shares or the par value of our common stock.

No fractional shares will be issued in connection with the Reverse Stock Split. Stockholders who otherwise would have been entitled to receive a fractional share in connection with the Reverse Stock Split will receive a cash payment in lieu thereof.

Our transfer agent, Computershare Trust Company, is acting as exchange agent for the Reverse Stock Split and will send instructions to stockholders of record regarding the exchange of certificates for common stock. Stockholders who hold their shares in brokerage accounts or in “street name” will not be required to take any action to effect the exchange of their shares.

On July 18, 2016, we also issued a press release with respect to the Reverse Stock Split described herein.

A copy of the Certificate of Amendment of our Restated Certificate of Incorporation is being filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference. A copy of the press release is being filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
