Exhibit 99.1

IWT TESORO CORPORATION AND INTERNATIONAL WHOLESALE TILE,
INC. FILE FOR CHAPTER 11 REORGANIZATION TO ADDRESS FINANCIAL
CHALLENGES

Tesoro, International Wholesale Tile, and all subsidiaries
Continue Normal Operations

WESTPORT, CT—(MARKET WIRE)—September 7, 2007—IWT Tesoro Corporation (OTCBB:IWTT) today announced that to address the slowdown in its business and other financial challenges, Tesoro, and its subsidiaries, International Wholesale Tile, Inc. (IWT) and American Gres, Inc. (AGI), have filed voluntary petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code.

Tesoro and each of its subsidiaries’ Board of Directors unanimously directed Tesoro, IWT and AGIto take this action after determining that a Chapter 11 reorganization is the best long-term interest of Tesoro and its subsidiaries, including IWT, their employees, customers, creditors, stockholders and other stakeholders.

Tesoro, IWT and AGI expect to continue normal business operations today and throughout the reorganization process. As part of the reorganization, Tesoro and IWT’s primary lender, Bank of America, has agreed to continue to provide financing to Tesoro and IWT.  The financing will include post-petition funds to acquire inventory, pay operating expenses and the costs of the Chapter 11 activities

“We believe this action is a responsible and necessary step to address our financial challenges and work to secure our future,” said Tesoro Chief Executive Officer Henry J. Boucher, Jr.  “Tesoro, IWT and all our subsidiaries are open for business as usual and will continue normal operations throughout the reorganization process, including employee wages and benefits, supplier payments, and other operating expenses during the reorganization process.   We hope that this act will preserve Tesoro’s and IWT’s value for our employees, customers, creditors and stockholders.  The Chapter 11 process allows us to continue normal operations while we restructure our debt and other obligations and to enhance performance.”

Tesoro’s, IWT’s, and AGI’s  Chapter 11 cases were filed today in U.S. Bankruptcy Court for the Southern District of New York.  They have filed a motion with the Court seeking interim relief that will ensure Tesoro, IWT and subsidiaries continued ability to conduct normal operations:  If such interim relief is granted by the Court, Tesoro and IWT will be authorized, among other things, to:

—Provide employee wages, savings plans, insurance plans and other similar programs and benefits without interruption;
—Continue their ordinary banking practices; and
—Continue shipping product to its customers.
