SSWM Reports 2006 Financial Results.

Company Closes U.S. Gas Station Projects to Concentrate on Mexico Environmental Infrastructure Projects

CARLSBAD, Calif. -- Sub-Surface Waste Management of Delaware, Inc., (OTCBB:SSWM) today announced audited financial results for fiscal year 2006 ended September 30, 2006.

SSWM CEO Bruce Beattie commented, "FY 2006 was clearly a transition year as we made the decision to close five retails gas station cleanups in the U.S. in favor of environmental infrastructure projects in Mexico where our full resources were successfully spent securing significant new contract work that will build and sustain a steady revenue stream in 2007 and beyond. Our current $2.4MM in projects in progress in Mexico already surpasses the 2006 total fiscal year revenues by almost 400% and we expect to increase this revenue rate as additional contracts with the State of Puebla, CFE (Comision Federal de Electricidad) and other clients begin in 2007. We have set the stage for significant growth in 2007 and beyond based upon proven technology, government enforcement, political support, and new financial and technical partnerships."

Results of Operations For Year Ended September 30, 2006

The Company's revenues for year ended September 30, 2006 were $508,460 compared to $1,094,775 for the year ended September 30, 2005; a decrease of 54 percent. Revenues decreased primarily due to the Company's withdrawal from its projects in South Carolina and from the time delay resulting from the startup of its operations in Mexico. Revenues for the year ended September 30, 2006, consisted primarily of bio-remediation of hydro-carbons in contaminated soil for the projects in Mexico. The Company incurred a gross profit loss for the year ended September 30, 2006 of $174,883 compared to $287,092 gross profit for the year ended September 30, 2005 primarily due to the write off of $201,641 of costs and estimated profits associated with the closure of the five active projects in South Carolina.

The Company incurred a net loss of $2,283,895 for the year ended September 30, 2006, compared to $1,627,719 for the year ended September 30, 2005. The Company had negative cash flows from operations of $740,675 for the year ended September 30, 2006, compared to negative cash flows from operations of $887,591 for the year ended September 30, 2005. Basic and diluted net loss per share was $0.03 for the year ended September 30, 2006 and $0.04 for the year ended September 30, 2005. Weighted average common shares outstanding increased from 43,249,462 for the year ended September 30, 2005 to 76,536,237 for the year ended September 30, 2006.

During the year ended September 30, 2006, the Company incurred $2,031,547 in selling, general and administrative expenses, compared to $1,762,396 for the year ended September 30, 2005. The increase in selling, general and administrative expenses of approximately $269,151 was primarily due to increases in legal, accounting, payroll expenses and business development expenses in Mexico.

Depreciation expense for the year ended September 30, 2006 was $24,714 compared to $13,233 for the year ended September 30, 2005. The increase was due principally to the purchase of equipment related to the startup of operations in Mexico. Interest expense for the years September 30, 2006 and 2005 respectively were $53,509 and $141,027. During this year notes payable decreased by $57,321 and therefore there was a decrease in interest expense.
