SouthWest Water Company Granted Nasdaq Listing Qualifications Hearing and Stay of Delisting

LOS ANGELES--(BUSINESS WIRE)--May 27, 2009--SouthWest Water Company (NASDAQ:SWWC), a leading provider of water, wastewater and public works services, today announced that the Nasdaq Hearings Panel has granted the company a Listing Qualifications Hearing, scheduled for June 11, 2009. The Panel has also granted the company a stay of delisting pending its broader review of the company’s reasons for its late filings and plan of compliance at the hearing.

As previously announced, the company is not in compliance with Nasdaq Marketplace Listing Rule 5250(c)(1) due to its failure to timely file its quarterly reports on Form 10-Q for the quarters ended September 30, 2008 and March 31, 2009, as well as its annual report on Form 10K for the year ended December 31, 2008. The delay in filing results is due to the previously announced restatement of prior period financials.
