FORWARD-LOOKING STATEMENTS

In addition to historical information, this Annual Report on Form 10-K contains forward-looking statements about TriCo Bancshares (the “Company,” “TriCo” or “we”) and its subsidiaries for which it claims the protection of the safe harbor provisions contained in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on the current knowledge and belief of the Company’s management (“Management”) and include information concerning the Company’s possible or assumed future financial condition and results of operations. When you see any of the words “believes”, “expects”, “anticipates”, “estimates”, or similar expressions, these generally indicate that we are making forward-looking statements. A number of factors, some of which are beyond the Company’s ability to predict or control, could cause future results to differ materially from those contemplated. These factors include those listed at Item 1A Risk Factors, in this report.

Forward-looking statements speak only as of the date they are made, and the Company does not undertake to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made, whether as a result of new information, future developments or otherwise.
