Item 8.01. Other Events

Cyanotech Corporation (the “Company”) will hold its Annual Meeting of Stockholders (the “2016 Annual Meeting”) on August 25, 2016 at 3:00 P.M., Hawaii Standard Time, at the Waikoloa Beach Marriott, 69-275 Waikoloa Beach Drive, Waikoloa, HI, USA 96738.

The date of the 2016 Annual Meeting represents a change of more than 30 days from the anniversary of the Company’s 2015 Annual Meeting of Stockholders held on October 15, 2015. As a result, pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended, the Company has set a new deadline for the submission of stockholder proposals submitted pursuant to Rule 14a-8 for inclusion in the Company’s proxy materials for the 2016 Annual Meeting. The new deadline for the submission of such stockholder proposals is the close of business on April 30, 2016, which the Company believes is a reasonable time for the review, consideration and, if appropriate, inclusion of any such proposals before it begins to print and send its proxy materials to stockholders for the 2016 Annual Meeting.

In accordance with the Company’s Amended and Restated Bylaws (the “Bylaws”), stockholders who intend to nominate a person for election as a director or submit a proposal regarding any other matter of business at the 2016 Annual Meeting must deliver written notice of such proposed business or nomination to the Company’s Secretary at the Company’s principal executive offices, no earlier than the close of business on April 27, 2016 (which is the 120th day prior to the date of the 2016 Annual Meeting) and no later than the close of business on May 27, 2016 (which is the 90^th day prior to the date of the 2016 Annual Meeting). Any notice of proposed business must comply with the specific requirements set forth in the Company’s Bylaws in order to be considered at the 2016 Annual Meeting.
