BioLargo, Inc. (the “Company”) expects to report that its net loss for the three- and nine-month periods ended September 30, 2007 was $481,824 and $2,768,913, or a loss of $0.01 and $0.11 per share, respectively. Comparatively, for the three- and nine-month periods ended September 30, 2006, net loss was $652,489 and $1,185,920, or a loss of $0.23 and $0.45 per share, respectively.

The decrease in loss in the three-month period ended September 30, 2007 is primarily attributable to the fact that there was revenue in 2007; non-cash expense recorded from the one time stock issuance to Ken Code pursuant to the 2006 R&D agreement; and decreases in selling, general and administrative expenses, research and development expenses and interest expense.

The increase in loss in the nine-month period ended September 30, 2007 is primarily attributable to non-cash interest and expense recorded from the conversion of notes payable and consultant obligations, because the conversion price was less than the market price of the Company’s stock at the date of conversion; and increases in selling, general and administrative expenses and interest expense; partly offset by revenue generated in 2007 and a decrease in research and development expenses.
