EXHIBIT 99.1 PRESS RELEASE OF AUGUST 19, 1998 Press Release For Immediate Release Contact: D. Linn Wiley President Chief Executive Officer (909)980-4030 CVB Financial Corp. Appeals Jury Verdict Ontario, California, August 19, 1998. CVB Financial Corp. (AMEX/CVB) today announced that its wholly owned subsidiary, Citizens Business Bank, has appealed the jury verdict in MRI Grand Terrace, Inc. vs. Chino Valley Bank. The appeal will be heard in the Fourth District Court of Appeal Division 2 in San Bernardino County, California. It is expected that the appeal process will take up to two years. The lawsuit relates to the sale of real estate owned by the Bank. A jury awarded approximately $4.9 million in a civil action in the Superior Court of San Bernardino County, California. The judgment includes approximately $2.1 million in compensatory damages, $1.6 million in punitive damages and $1.2 million in prejudgment interest. A motion to vacate the jury verdict and a motion for a new trial were denied on August 14, 1998. Linn Wiley, President and Chief Executive Officer of CVB Financial Corp., said "We are at a loss to understand the rationale for this decision. We believe our position is clearly supported by the facts, and the verdict is inconsistent with other findings made by the jury in the trial. Therefore, we expect to be fully exonerated through the appellate process." A final judgment for $4.9 million would reduce net earnings of the Company by approximately $3.0 million. CVB Financial Corp. reported net earnings of $17.4 million for the year ending December 31, 1997. Net earnings for the first six months ending June 30, 1998 were $9.8 million. Total assets were $1.4 billion, and stockholder's equity was $108.3 million. 6
