REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Plan Participants and Plan Administrator of

Umpqua Bank 401(k) and Profit Sharing Plan

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the Umpqua Bank 401(k) and Profit Sharing Plan (the "Plan") as of December 31, 2018 and 2017, the related statement of changes in net assets available for benefits for the year ended December 31, 2018, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2018 and 2017, and the changes in net assets available for benefits for the year ended December 31, 2018, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on the Plan's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

Report on Supplemental Schedule

The supplemental schedule of assets (held at end of year) as of December 31, 2018 has been subjected to audit procedures performed in conjunction with the audit of the Plan's financial statements. The supplemental schedule is the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental schedule reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedule. In forming our opinion on the supplemental schedule, we evaluated whether the supplemental schedule, including its form and content, is presented in compliance with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, such schedule is fairly stated, in all material respects, in relation to the financial statements as a whole.

UMPQUA BANK 401(k) AND PROFIT SHARING PLAN

NOTES TO FINANCIAL STATEMENTS

Note 1 – Description of Plan

The following description of theUmpqua Bank 401(k) and Profit Sharing Plan (the Plan) provides only general information. Participants should refer to the Plan Agreement, as amended, for a more complete description of Plan provisions.

General – The Plan is a 401(k) salary deferral and profit sharing plan covering substantially all employees of Umpqua Holdings Corporation and Subsidiaries (the Company), and is subject to provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). The Company is the Plan's sponsor and serves as Plan administrator.

Eligibility – Employees of the Company are eligible to participate in the Plan upon reaching age 18 and after completing one hour of service. Employees are automatically enrolled into the Plan once they meet these criteria, unless they choose to opt-out. Employees enter the plan on scheduled enrollment dates following their completion of the eligibility requirements.

Contributions –

Employee deferrals –Participants may elect to contribute up to 80% of eligible compensation, except for bonus pay which can be deferred up to 100%, to the Plan each year. In addition, participants may make voluntary Roth after-tax contributions or voluntary non-deductible after-tax contributions to the Plan. Participants may also roll over eligible amounts from other qualified plans.

Employer match –The Company may elect to make discretionary matching contributions to the Plan. The contribution period is each Plan year and Participants must be employed as of the last day of the year to be eligible to receive any matching contributions for that year. The Company matched 50% of employee contributions, up to 6% of eligible compensation deferred to the Plan for the year ended December 31, 2018.

Employer profit sharing –The Company may elect to make discretionary profit sharing contributions to the Plan. Participants must complete at least 1,000 hours of service during the Plan year, and be employed as of the last day of the Plan year, to be eligible to receive any profit sharing contributions. Profit sharing contributions are allocated to participants in the same proportion as a participant's compensation bears to the total of all participants' compensation. For the year ended December 31, 2018, the Company made a profit sharing contribution of $2,873,396 that was funded in 2019 and a profit sharing contribution of $3,149,584 for the year ended December 31, 2017 that was funded in 2018.

Contributions are subject to regulatory limitations.

Participant accounts –Each participant's account is credited with the participant's contribution and allocations of the Company's contributions and Plan earnings, and charged with an allocation of administrative expenses. Allocations are based on participant earnings or account balances, as defined. Participants direct the investment of their account balances into various investment options offered by the Plan. The Plan currently offers various registered investment company mutual funds, Company common stock and a stable value fund as investment options for participants. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.

NOTES TO FINANCIAL STATEMENTS

Note 1 – Description of Plan (continued)

Vesting – Participants are fully vested at all times in that portion of their accounts attributable to their own contributions and earnings or losses thereon. Vesting in Company contributions is based on years of service pursuant to the following vesting schedule. Participants who were part of acquired plans may have specific vesting schedules in accordance with those plans.

		Percentage
Years of service
	Less than 1 year	—%
	1 year but less than 2	20%
	2 years but less than 3	40%
	3 years but less than 4	60%
	4 years but less than 5	80%
	5 years or more	100%

Notes receivable from participants – Participants may borrow from their accounts a minimum of $1,000 up to 50% of participants' vested accounts, but not in excess of $50,000. Loans are secured by the balance of the participant's account and bear fixed, reasonable rates of interest, as determined by the plan administrator. The maximum loan term is five years unless the loan qualifies as a home loan. Principal and interest are paid ratably through payroll deductions. As of December 31, 2018, the rates of interest on outstanding loans ranged from 4.25% to 9.25% with various maturities through January 2039.

Payment of benefits – On termination of service due to death, disability, or retirement, a participant may elect to receive a lump-sum amount equal to the value of the participant's vested interest in his or her account balance, or annual installments over a period not more than the participant's life expectancy (or the assumed life expectancies of the participant and their beneficiary). For termination of service for other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution.

Hardship withdrawals of the participants' contributions are permitted by the Plan. Hardship withdrawals must be approved by the Plan administrator, and are limited to vested amounts of participants' contributions. Hardship withdrawals require a six-month suspension from contributing to the Plan from the date of receipt of the hardship withdrawal.

Forfeitures – Forfeitures are the nonvested portion of a participant's account that are lost upon termination of employment. Forfeitures are retained in the Plan and will be used to reduce future Company contributions. As of December 31, 2018 and 2017, forfeited non-vested accounts totaled $120,051 and $24,990, respectively. During 2018, the Company used $475,970 of forfeitures to fund 2018 contributions. During 2019, the Company used $119,000 of forfeitures to fund 2018 contributions.

NOTES TO FINANCIAL STATEMENTS

Note 2 – Summary of Significant Accounting Policies

Basis of accounting – The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, using the accrual method of accounting.

Use of estimates – The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions that may affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates.

Investment valuation – Investments are stated at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability (i.e., the "exit price") in an orderly transaction between market participants at the measurement date. See Note 3 for discussion of fair value measurements.

Notes receivable from participants – Notes receivable from participants are measured at amortized cost, which represents unpaid principal balance plus accrued but unpaid interest. Delinquent notes receivable from participants are recorded as distributions based on the terms of the Plan Document.

Income recognition – Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. Interest income is recorded on the accrual basis. The net appreciation (depreciation) in fair value of investments consists of both the realized gains or losses and unrealized appreciation and depreciation of those investments.

Payment of benefits – Benefit payments are recorded when paid.

Expenses – Administrative expenses such as legal and accounting fees are paid by the Company. Reasonable and permissible expenses directly attributable to the administration and servicing of the Plan, such as transaction fees and investment management fees are paid by the Plan.

Subsequent events –Subsequent events are events or transactions that occur after the statement of net assets available for benefits date but before financial statements are issued. The Plan recognizes in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the statement of net assets available for benefits, including the estimates inherent in the process of preparing the financial statements. The Plan's financial statements do not recognize subsequent events that provide evidence about conditions that did not exist at the date of the statement of net assets available for benefits but arose after the statement of net assets available for benefits date and before financial statements are issued.

Note 3 – Fair Value Measurements

The fair value framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurement) and the lowest priority to unobservable inputs (level 3 measurements).

The asset or liability's fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used maximize the use of observable inputs and minimize the use of unobservable inputs.

The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2018 and 2017.

Registered investment companies (mutual funds) – Valued at quoted market prices, which represent the net asset value (NAV) of shares held by the plan at year end.

Registered investment companies (money market funds) – The money market funds are valued using the NAV of the money market as reported by the money market managers, as a practical expedient. The NAV is based on the fair value of the underlying assets in the money market fund, minus its liabilities, and then divided by the number of units outstanding.

The money market funds invest in securities determined to experience minimal credit risk such as U.S. government securities and other short-term obligations of U.S. companies, states, and municipalities. The money market fund seeks to maintain a stable NAV of $1.00 per share. Principal risks of the money market fund could cause deterioration in the stable NAV which could result in increased redemption activity further adversely affecting the NAV. The money market funds measured at NAV have not been classified in the fair value hierarchy.

Common stock – Valued at the closing price reported on the active market on which the individual securities are traded. Common stock is generally classified within level 1 of the valuation hierarchy.

Collective trust – Units held in the collectivetrust are valued using the NAV of the fund. The NAV is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying assets owned by the fund, minus its liabilities, and then divided by the number of units outstanding. Participant transactions (purchases and sales) may occur daily at NAV. The common collective trust funds measured at NAV have not been classified in the fair value hierarchy.

The valuation methods used by the Plan may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Note 4 – Tax Status

The Internal Revenue Service has determined and informed the Company by a letter dated May 11, 2017, that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (IRC). Although the Plan has been amended since receiving the determination letter, the plan administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. Plan management must evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the organization has taken an uncertain tax position that more likely than not would not be sustained upon examination by the Internal Revenue Service. The plan administrator has concluded that as of December 31, 2018 and 2017 there were no uncertain tax positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements.

Note 5 – Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks, such as interest rate, market volatility, and credit risk. It is reasonably possible that, given the level of risk associated with investment securities, changes in the near term could materially affect a participant's account balance and the amounts reported in the financial statements.

Note 6 – Party-in-Interest Transactions

Plan investments include shares of Umpqua Holdings Corporation Stock which is comprised of common stock of the Company. Certain Plan investments are shares of mutual funds managed by Fidelity Investments, which is the trustee of the Plan. These transactions qualify as party-in-interest transactions.

Note 7 – Plan Termination

Although it has not expressed any intention to do so, the Company has the right to terminate the Plan and discontinue its contributions at any time. If the Plan is terminated, amounts allocated to a participant's account become fully vested.

Note 8 – Subsequent Event

As of April 1, 2019, the Plan was amended to offer participants a self-directed brokerage account option, that will allow employees to buy or sell individual securities. The amendment also updated the entry date to the Plan to the first day of each month as compared to the first day of the month following quarter end. In addition, the automatic enrollment default deferral percentage was increased from 4% to 6%, effective April 1, 2019. During 2019, the Company increased the discretionary match from 50% of employee contributions, up to 6%, to 50% of employee contributions up to 8%, in lieu of future profit sharing contributions.
