WATERTOWN, Mass — Dynasil Corporation of America (NASDAQ: DYSL), a leading developer of sensing, detection and analysis technology for homeland security, medical and industrial applications, today announced financial results for fiscal year ended September 30, 2012 and the filing of its Annual Report on Form 10-K within the extension period provided by Rule 12b-25.

“We made significant investments during fiscal 2012 to launch two refreshed products – the LPX Pro Lead Paint Analyzer and the Navigator 2.0 gamma probe – but continue to await the regulatory approvals that would enable us to bring those devices to market”

Total revenue for fiscal 2012 increased to $47.9 million from $47.0 million in fiscal 2011. Contract Research segment revenue decreased to $24.3 million from $24.9 million in fiscal 2011. The Company’s newly named Optics segment (previously part of the “Products & Technology” segment) posted revenue of $17.5 million, up from $15.8 million a year earlier. Instruments segment (also previously part of the “Products & Technology” segment) revenue remained relatively flat at $6.1 million, compared with $6.2 million in 2011. The newly created Biomedical segment achieved its first revenues of $0.1 million in fiscal 2012.

Gross profit for fiscal 2012 totaled $20.0 million, or 40.7% of net revenue, compared with $19.8 million, or 42.1% of revenue for fiscal 2011. Gross profit margin declined as a result of higher costs within the Contract Research segment.

Selling, general and administrative expenses for fiscal 2012 totaled $21.0 million, versus $17.5 million for fiscal 2011, primarily reflecting investments in the Company’s Instruments segment and Biomedical segment pipelines to support future growth. These investments include technology development activities and staff additions in support of organic product development. In addition, the Company incurred a significant, non-recurring charge of approximately $466,000 to its selling, general and administrative expenses during that quarter related to costs incurred as a result of a review, under the direction of the Audit Committee of the Board, of certain cash application processes and billing practices of the RMD division. This investigation has been completed and has resulted in modifications in the division’s practices and internal controls. The Company does not anticipate additional expenses for this matter.

As a result of higher-than-expected costs and product launch delays, the Company determined that there was a decline in the fair value of its Instruments segment, and recorded a non-cash goodwill impairment charge of $2.3 million for the three-month period ended September 30, 2012.

“We made significant investments during fiscal 2012 to launch two refreshed products – the LPX Pro Lead Paint Analyzer and the Navigator 2.0 gamma probe – but continue to await the regulatory approvals that would enable us to bring those devices to market,” said Dynasil Chairman and Interim CEO Peter Sulick. “The increased expenses also reflected further investment in our dual mode detector program and our biomedical business. In addition, we incurred expenses for a review of certain cash application processes and billing practices at our RMD division. Going forward, we are focused on improving our liquidity and pursuing strategic initiatives that best position the company for future profitable growth.”

Including the goodwill impairment charge, net loss for the 12 months ended September 30, 2012 was $4.3 million, or $0.29 per share, compared with net income of $1.4 million, or $0.08 per diluted share, for the 12 months ended September 30, 2011.

Liquidity

As previously disclosed, as of September 30, 2012, Dynasil is in default with its financial covenants under the Company’s loan agreements. Dynasil continues to be current with all principal and interest payments due on all its outstanding indebtedness and management expects to continue discussions with its lenders to address the financial covenant situation. These financial covenant defaults give the lenders the right to accelerate the maturity of the indebtedness outstanding and foreclose on any security interest. Furthermore, Sovereign Bank, N.A., the Company’s senior lender, may, at its option, impose a default interest rate with respect to the senior debt outstanding, which is 5% higher than the rate otherwise in effect. To date, the lenders have not taken any such actions. However, the Company cannot predict when or whether a resolution of this situation will be achieved.

The Company has taken and will continue to take actions to improve its liquidity, including the implementation of a number of initiatives designed to conserve cash, optimize profitability and right-size the cost structure of its various businesses. Dynasil has retained Argus Management Corporation and Mirus Capital as financial advisors to assist it in evaluating strategic and restructuring alternatives, including the potential sale of product lines and/or a Company division. While the Company is actively considering such strategic alternatives, there can be no assurances that any such transaction will occur, or, if a transaction is completed, it will be on terms favorable to the Company.

Because of the uncertainty of any resolution of the covenant violations and possibility of an acceleration of the indebtedness by the lenders, the Company has reclassified all of its outstanding indebtedness as a current liability in the financial statements for year ended September 30, 2012 filed and the Company’s independent registered public accountants has included a “going concern” qualification in its audit opinion with respect to such financial statements.
