CHICAGO, IL, August 11, 2005 — Quixote Corporation (Nasdaq: QUIX) today reported results for its fourth quarter and fiscal year ended June 30, 2005.

Net sales for the fourth quarter of fiscal 2005 were $39,967,000, compared with net sales of $39,443,000 in the fourth quarter of fiscal 2004. Operating profit was $2,568,000 in the fiscal 2005 fourth quarter, compared to an operating loss of $30,479,000 for the fourth quarter last year.

Leslie J. Jezuit, Chairman and Chief Executive Officer, commented, “Fiscal 2005 was another challenging year for Quixote as the prolonged lack of new federal highway legislation and the resulting constraints on state and municipal spending continued to affect demand for our products during the quarter. However, we were encouraged that while our sales for the fourth quarter were only slightly higher year-over-year, we achieved gross margin improvements as well as an increase in operating profit. Gross margins improved to 36.3% in the fourth quarter, compared to 34.2% last year, despite higher raw material costs. Operating profit also increased despite higher costs related to Sarbanes-Oxley compliance. With the lack of new highway legislation in fiscal 2005, we focused on rationalizing certain product lines, reorganizing our manufacturing facilities, and lowering our head count, in order to match sales levels while maintaining the research and development levels necessary to continue investing in the future. We believe we have taken the major actions necessary to improve our cost structure, and are now focused on growing the top-line as the industry recovers.”

Mr. Jezuit continued, “We are particularly pleased with our continued strong international performance, as international sales increased an impressive 68% during the fourth quarter. Total revenues from our Protect and Direct Group increased 5% versus year ago levels, driven by an increase in sales of our permanent crash cushions. In the Inform Group, revenues declined 2%, as lower sales of our intersection control products offset increased sales of highway advisory radio products.”

Mr. Jezuit concluded, “After an almost two-year delay and eleven extensions to the prior bill, yesterday the President signed into law new federal highway legislation known as SAFETEA-LU, or the “Safe, Accountable, Flexible and Efficient Transportation Equity Act - A Legacy for Users”. SAFETEA-LU will provide $286.4 billion in guaranteed funding for the federal highway, transit and safety programs through 2009. Importantly, the new bill focuses on improving safety and relieving congestion as well as on new highway construction and resurfacing projects. Even though our operating results are improving, we don’t expect to realize the full benefit of the bill’s passage until the second half of fiscal 2006. We expect earnings per share for the first quarter of fiscal 2006 of between $0.02 and $0.05 per diluted share.”
