EXPLANATORY NOTE





This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends our Annual Report on Form 10-K for the fiscal year ended March 31, 2015, originally filed with the Securities and Exchange Commission on July 15, 2015 (the “Original Filing”). We are filing this Amendment to amend and restate Part III of the Original Filing to include the information required by and not included in Part III of the Original Filing, as we have not filed our definitive proxy statement for an annual meeting of stockholders within 120 days of the end of our fiscal year ended March 31, 2015.  In addition, in accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Item 15 of Part IV of the Form 10-K has been amended to include as exhibits new certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 by the Company’s principal executive officer and principal financial officer, with paragraphs 3, 4 and 5 omitted since no financial statements are contained within this Amendment. This Amendment does not change the previously reported financial statements or any of the other disclosures contained in Part I, Part II or Part IV, other than as described above.



Except as described above, no other changes have been made to the Original Filing.  The Original Filing continues to speak as of the date of the Original Filing, and we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the Original Filing. Accordingly, this Amendment should be read in conjunction with the Original 10-K and the Company’s other filings with the SEC subsequent to the Original Form 10-K.

The Board has determined that each member of the Audit Committee is an “independent director” under the Nasdaq and SEC rules applicable to Audit Committee members. The Board has determined that Ralph K. Carlton is an “audit committee financial expert” as defined in Item 407 of Regulation S-K promulgated under the Exchange Act, and thus possesses “financial sophistication” as that term is defined by applicable Nasdaq listing rules. The Audit Committee operates and acts under a written charter adopted by the Board. A copy of the Charter and Powers of the Audit Committee can be found on the Company’s website at www.cyanotech.com.

Narrative Discussion of Summary Compensation Table



Theelements of the Company’s executive compensation include base salary, bonus, if awarded, and stock option awards. Base salary increases for the executive officers are reviewed on an annual basis by the Compensation Committee of the Board of Directors. Base salary increases of the named executive officers in fiscal year 2015 averaged 5.2% and were based on individual and company performance for fiscal year 2014.



The Committee believes that, as a general rule, annual compensation in excess of base salaries should be dependent on the Company’s performance, and should be awarded based on recommendations of the Chief Executive Officer to the Committee and in the discretion of the Board. Accordingly, each fiscal year, the Committee reviews and approves a cash incentive bonus plan designed to motivate executive officer and key personnel to achieve the financial and operational objectives of the Company. No bonuses have been awarded for fiscal 2015 performance.



On November 5, 2010, the Board of Directors of the Company entered into an employment agreement with Mr. Bailey, which provides for a term of up to seven years with a beginning salary of $300,000 and participation in an annual incentive program with a target bonus opportunity of 50% of his then-current salary, plus an opportunity for a greater bonus if he achieves stretch goals measured by compound annual earnings growth significantly exceeding fiscal year earnings goals, subject to the Board’s discretion.  In addition, as part of the agreement Mr. Bailey was granted stock options equivalent to approximately 131⁄2% of all issued and outstanding shares of the Company’s common stock as of the actual date of commencement of his employment term.  Such options vest and become exercisable in increasingly larger increments on the anniversary dates of the commencement date of his employment.



The 2005 Stock Option Plan (the “2005 Plan”) rewards select executives and key employees as an incentive for them to join or remain in the service of the Company. The Compensation and Stock Option Committee administers this Plan. There were no stock option grants awarded to any of the named executive officers in fiscal 2015.
