Exhibit 99.1 Southwest Water Company Reports Third Quarter 2004 Revenues and Earnings LOS ANGELES--(BUSINESS WIRE)--Nov. 9, 2004--Southwest Water Company (Nasdaq:SWWC) today is reporting revenues and earnings for the third quarter ended September 30, 2004. The company is also updating its business outlook for the remainder of 2004. Third Quarter 2004 Summary, Compared with Third Quarter 2003: -- Revenues were $55.0 million, compared with $51.4 million. -- Operating income totaled $5.0 million, compared with $6.6 million. -- Net income was $2.4 million, compared with $3.4 million. -- Diluted earnings per share totaled $0.13, compared with $0.22. As a result of two public offerings in 2004, the weighted average number of shares outstanding increased by 19 percent, compared with the third quarter of 2003. Anton C. Garnier, Southwest Water chairman and chief executive officer, said, "Financially, the third quarter was very challenging, with a combination of several events that impacted our operations. Our Utility Group profitability was adversely affected by two source of supply issues in our Southern California utility at the height of the summer water demand. A break in a major pipeline owned by a third-party water supplier forced our utility to purchase significantly more expensive Metropolitan Water District water. Secondly, we lost production from one of our wells, which also caused us to purchase substantially higher priced water. We are working to replace this well, and we expect that both of these events will not affect our earnings going forward." Garnier continued: "In our Services Group, unexpected delays in obtaining permits for construction projects in Texas impacted our third quarter operating profit. Some of these delayed projects broke ground in the fourth quarter, but we do not anticipate making up the earnings shortfall associated with the delays in the remainder of this year. Finally, in our Services Group, we completed several acquisitions in our multi-family billing and collection subsidiary in the first half of this year. As we have integrated those acquisitions, we realized the benefits of focusing our ongoing marketing efforts on third-party equipment; consequently, we took an inventory valuation reserve of approximately $300,000 for our proprietary equipment. "The impact of these operational events and inventory valuation adjustments is a reduction in pre-tax income of approximately $1,500,000, and because we do not see a recovery of these expenses in the fourth quarter, we are changing our 2004 guidance for accordingly." Garnier noted, "In comparing the third quarter of 2004 with the third quarter of 2003, we have incurred significantly higher selling, general and administrative expenses due to our compliance efforts with the Sarbanes-Oxley Act, including independent auditor fees, independent internal audit fees, board governance fees and engagement of consultants for the purpose of completing documentation and testing required by Sarbanes-Oxley Section 404." Garnier added, "On a positive note, during the third quarter we completed the acquisition of approximately 25,000 utility accounts from Tecon Water Holdings, L.P. This utility, which we have renamed Monarch Utility Company, Inc., is outperforming our internal plans for revenues and profitability. During the fourth quarter, we settled a pending rate case for the utility at approximately 80 percent of the increase originally requested by Tecon. The remaining 20 percent of the original request will be added to customer rates in October 2005." Garnier concluded, "The past quarter was challenging, but we believe that our underlying businesses remain strong. We will continue to strategically review the performance of each business unit and make changes as warranted. We remain focused on long-term revenue growth and profitability improvement." Business Outlook The company's revised outlook for 2004 anticipates: -- Revenues of approximately $190 million, up from prior guidance of $185 million; -- Operating income of $17 million, down from prior guidance of $19 million; -- Income before taxes of $12.5 million, down from prior guidance of $14 million; -- Net income of $8 million, down from prior guidance of $9 million. Revenue guidance assumes normal weather conditions during the fourth quarter.
