Tronox Identifies Factors That Will Impact Second-Quarter Financial Results

Oklahoma City, July 11, 2007 – Tronox Incorporated (NYSE: TRX, TRX.B) identified factors that will impact second-quarter financial results, including production difficulties at one of its titanium dioxide plants, an environmental provision and a tax charge. Market dynamics, as previously projected by the company, continue to be a challenge as a result of second-quarter softness in the United States housing market in conjunction with rising input costs.

The company reported its titanium dioxide plant in Botlek, Netherlands, experienced production difficulties during the second quarter which are expected to result in increased pretax costs for the quarter of approximately $3 million. Production at the Botlek plant, which has an annual capacity of 90,000 tonnes, returned to normal levels after necessary repairs were completed.

Tronox also expects to record a pretax noncash environmental provision, net of expected insurance reimbursements, of approximately $2 million in the second quarter for costs associated with an ongoing environmental assessment at its Henderson, Nev., site. This provision does not reflect Kerr-McGee’s reimbursement obligation, which is 50% of the remediation costs incurred by Tronox in excess of reserves established as of the initial public offering, subject to previously disclosed limitations. The noncash provision will be reported as part of “Income (Loss) from Continuing Operations” in the company’s second-quarter financial results.

Tronox also expects to record noncash tax charges of approximately $4 million as a result of additional discussions with German tax authorities pertaining to the company’s ongoing income tax audit for the years 1998 through 2001.

Tronox will announce its second-quarter 2007 financial results Aug. 1, at 7 a.m. EDT and hold a conference call at 11 a.m. EDT to discuss its financial and operating results and expectations for the future.
