(OTC BB: SONX), a leader in the field of combustion technology, last week filed for an automatic extension of time to submit its Annual Report on Form 10-KSB for the year ended December 31, 2004. The date for filing the Form 10-KSB with the Securities and Exchange Commission (SEC), originally March 31, 2005, is now April 15, 2005, but the Company now reports that it will not make the filing by this extended due date. In addition, Dr. Andrew A. Pouring, Sonex Chairman of the Board, CEO and President, reports that the Company has substantially completed work under its ongoing agreement with the Defense Advanced Research Projects Agency (DARPA) on a project to develop a "heavy fuel" engine (HFE) combustion process for potential Department of Defense (DoD) applications such as unmanned aerial vehicles (UAVs). He explained that Sonex has demonstrated the potential for lightweight, multi-cylinder engines running on JP-5, military kerosene-based heavy fuel by application of a Sonex Combustion System (SCS) unthrottled, direct fuel injection combustion process based on the Sonex Controlled Auto-Ignition (SCAI) technology. The SCAI process is enabled by a proprietary Sonex piston technology that achieves in-cylinder chemical kinetics at a moderate compression ratio for auto ignition of the JP-5 to achieve engine stability and control, and fuel consumption substantially lower than a gasoline baseline engine. Dr. Pouring suggested that outcomes from the DARPA program could validate the sparkless SCAI process for in-cylinder control of ignition and combustion for potential application to gasoline powered automobiles to achieve better fuel economy. He added that the Company hopes to be in a position to announce more specific project results in the near future following acceptance by DARPA of the Company's project report. In its SEC filing for the extension of time to submit the 2004 Form 10-KSB, Sonex explained that it did not have the funds to engage its independent accountants to conduct the audit of the December 31, 2004 financial statements, and that its limited staff did not have time to prepare the Form 10-KSB document. The Company had also cautioned that it might not be in a position to file the Form 10-KSB by the extended due date, but it now indicates that it will not make the filing by April 15, 2005. Sonex CFO, Secretary and board member George E. Ponticas reports that the time spent this year by Dr. Pouring and he dealing with an investor lawsuit, and the legal fees required, were among the factors resulting in the Company's inability to prepare and file the Form 10-KSB. He added that failure to file the Form 10-KSB by the extended due date may have significant implications for the Company until the filing is made, including the inability to register stock with the SEC and inability for shareholders to sell restricted stock. Sonex will use its best efforts to file the report as soon as resources permit. While the Company continues to experience cash flow problems, Dr. Pouring expressed optimism that revenue from the DARPA agreement, the modest amounts of revenue being earned from work on HFEs for small UAV applications, and additional short-term loans from shareholders will provide Sonex the time to secure needed additional capital and/or revenue, and hire sufficient experienced personnel, to take advantage of a number of potential business opportunities. There is no assurance, however, that the Company will be able to achieve these objectives. The Company's history of operating losses, significant financial liabilities, and other risk factors mean that there still remains substantial doubt about the Company's ability to continue as a going concern. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
