SEATTLE, WA — (Marketwire – June 2, 2011) – HQ Sustainable Maritime Industries, Inc. (AMEX:HQS – News) (“HQS” or the “Company”), a leading producer and marketer of health products derived from marine based raw materials as well as Tilapia resulting from vertically integrated operations, announced today it received a continued listing deficiency notice from the NYSE Amex LLC (the “Exchange”) relating to the Company’s inability to timely file its Quarterly Report on Form 10-Q for the period ended March 31, 2011 (the “Quarterly Report”). Sections 134 and 1101 of the Exchange Company Guide (the “Company Guide”) require timely filing of such periodic reports with the Securities and Exchange Commission. The staff of the Exchange (the “Staff”) cited the Company’s failure to file its Quarterly Report within the prescribed filing deadline in its determination that the Company has failed to comply with certain continued listing standards of the Exchange.

As previously reported, the Company remains out of compliance with continued listing standards set forth under Sections 134 and 1101 of the Company Guide since the Company is yet to file its Annual Report on Form 10-K for the fiscal year ended December 31, 2010. In addition, on April 11, 2011, the Company was notified of non-compliance with continued listing standards set forth under Sections 802(a) and 803(B)(2)(a) of the Company Guide. The foregoing Sections require a listed company to maintain a majority of independent directors on its Board of Directors and at least three independent directors on the company’s Audit Committee. The trading in the Company’s securities remains halted.

The Company submitted to the Staff a plan of compliance in connection with the continued listing deficiencies. If the Company’s plan to regain compliance is accepted by the Exchange, the Company may be able to continue its listing during this period, during which time it will be subject to periodic review to determine progress consistent with the plan. If, however, the plan is not accepted by the Exchange, the Company will be subject to delisting procedures as set forth in the Company Guide. Under Company Guide rules, the Company has the right to appeal the determination by the Exchange staff to initiate delisting proceedings. There is no assurance that the Exchange staff will accept the Company’s plan of compliance or that, even if such plan is accepted, the Company will be able to implement the plan within the prescribed timeframe.
