Item 7.01. Regulation FD Disclosure.

Umpqua Holdings Corporation has posted the summary results of its company-run 2017 capital stress test as required under Section 165(i)(2) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and in accordance with regulations of the Board of Governors of the Federal Reserve System (“Federal Reserve”). The stress test results can be found on our Investor Relations website (https://www.umpquabank.com/ask-us/investor-relations/) under the heading “Financial Information.” The stress test results are based on a forward-looking exercise using hypothetical severely adverse macroeconomic assumptions developed and provided by the Federal Reserve. The stress testing requirements are specified by Federal Reserve regulations, but the processes and modeling methodologies used in the stress test are specific to us; therefore, our stress test results are not directly comparable to those disclosed by other bank holding companies since modeling techniques, processes and assumptions could differ significantly across companies. Our results are not intended to reflect our expectations about future economic conditions and should not be taken as an indication of our expected present or future financial results.

Information contained herein shall not be deemed filed for the purposes of the Securities Exchange Act of 1934, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933, except as shall be expressly set forth by specific reference in such a filing.
