On July 24, 2018, Superconductor Technologies Inc. (the “Company” or “we” or “our”) effected a one-for-ten (1-for-10) reverse stock split of our common stock, par value $0.001 (the “Reverse Stock Split”). The Company filed a Certificate of Amendment (the “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, at our annual meeting of stockholders adjourned to June 15, 2018, 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-4 and not more than 1-for-10. Our board of directors thereafter selected the 1-for-10 reverse stock split ratio and authorized the implementation of the Reverse Stock Split.

As a result of the Reverse Stock Split, every ten (10) 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 began trading on July 24, 2018 with a new CUSIP number of 867931 602. 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 23, 2018, we issued a press release with respect to the Reverse Stock Split described herein.
