CHICAGO, Dec. 21, 2009 (GLOBE NEWSWIRE) — Quixote Corporation (Nasdaq:QUIX)(“Quixote”) today announced that it has sold the stock of the companies comprising its Inform segment to Vaisala, Inc., a subsidiary of Vaisala Oyj, a global leader in environmental and industrial measurement systems, in an all cash transaction valued at $20 million. The Inform segment recorded revenue of $22.6 million, or 24% of total revenue, in fiscal 2009.

The segment is known as Quixote Transportation Technologies, Inc., and includes the subsidiaries Surface Systems, Inc., Nu-Metrics, Inc., and Highway Information Systems, Inc. The FreezeFree(R) bridge anti-icing product line will remain with Quixote and will be sold through its Quixote Transportation Safety, Inc. subsidiary.

Bruce Reimer, Chief Executive Officer and President of Quixote Corporation, commented, “We are very pleased to have completed this transaction which significantly strengthens our balance sheet and enables us to focus on our strong crash cushion and delineator product lines within the Protect and Direct segment. We are now able to allocate more resources toward important new market opportunities and innovative product extensions to further enhance our leadership positions both domestically and internationally.”

Mr. Reimer continued, “The divestiture of the Inform segment is a critical element of our strategy to meet our obligations under the $40 million in convertible debentures, which are effectively due February 15, 2010, and puts us in a better-position to obtain the remaining financing necessary to meet those obligations.”
