American Technologies Group Announces Increase in Revenues From Technology Products.

MONROVIA, Calif.--(BUSINESS WIRE)--June 23, 1999--

American Technologies Group, Inc (ATG) (OTC BB:ATEG), announced it has filed its form 10-QSB for the third quarter and nine month results ended April 30, 1999. Revenues from technology products increased 27% for the third quarter as compared to the same quarter in 1998.

Commenting on the increase, Lawrence J. Brady, ATG's chairman and chief executive officer, stated, "The increase in sales revenue is the best indication yet that the course on which we embarked in early 1998 was correct, and remains so. The refocus of the company from research and development to commercialization and sales is working."

Brady went on to say, "It is of note that much of the third quarter revenue was generated during the last month of the quarter. As evidenced by several of our recent announcements, it seems probable that this trend toward increasing sales will continue and, in fact, accelerate. While the dollar amounts are still modest, the percentage increase, which is a real indicator of our successful actions, is impressive."

Brady concluded his comments by saying, "We expect a good, strong showing in this, the last quarter of our fiscal year, and we believe that we are firmly on the road to profitability."
