REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees

Umpqua Bank 401(k) and Profit Sharing Plan

We have audited the accompanying statements of net assets available for benefits of Umpqua Bank 401(k) and Profit Sharing Plan (the “Plan”) as of December 31, 2014 and 2013, and the related statement of changes in net assets available for benefits for the year ended December 31, 2014. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as ofDecember 31, 2014 and 2013, and the changes in net assets available for benefits for the year ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America.

The supplemental information included in Schedule H, line 4(i) - Schedule of assets (held at end of year)has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental information 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 information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with Department of Labor's Rules and Regulations for Reporting and Disclosure under ERISA. In our opinion, the supplemental information included in Schedule H, line 4(i) - Schedule of assets (held at end of year) is fairly stated, in all material respects, in relation to the financial statements as a whole.

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 chose to opt-out.

Contributions –

Employee deferrals –Participants may elect to contribute up to 80% of eligible compensation, except for bonus pay which can be be deferred up to 100%, to the Plan each year. 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 quarter and Participants must be employed as of the last day of the Plan quarter, to be eligible to receive any matching contributions for that quarter. The Company matched 50% of employee contributions, up to 6% of eligible compensation deferred to the Plan for the year ended December 31, 2014.

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. There were no profit sharing contributions for the year ended December 31, 2014.

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 contribution 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 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 term qualifies as a home loan. Principal and interest are paid ratably through payroll deductions. As of December 31, 2014, the rates of interest on outstanding loans ranged from 4.25% to 9.25% with various maturities through December 2034.

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.

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, 2014 and 2013, forfeited non-vested accounts totaled $481,389 and $137,515, respectively. For the year ended December 31, 2014, the Company contributions were reduced by $518,422 from forfeited non-vested accounts.

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 4 for discussion of fair value measurements.

Investment contracts held by a defined contribution plan are required to be reported at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The statements of net assets available for benefits present the fair value of the investments, as well as the adjustment from fair value to contract value for fully benefit-responsive investment contracts. The statement of changes in net assets available for benefits is prepared on a contract value basis, which approximates fair value at the reporting date.

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 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. Transaction fees and investment management fees are paid by the Plan.

Note 2 – Summary of Significant Accounting Policies (continued)

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. The Plan has been evaluated for subsequent events through June 29, 2015, which is the date the financials were issued.

Note 3 – Investments

Note 4 – Fair Value Measurements

FASB Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures, provides the framework for measuring fair value. That 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 three levels of the fair value hierarchy under FASB ASC 820 are described as follows:

Basis of fair value measurement –

Level 1 – Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the plan has the ability to access.

Level 2 – Inputs to the valuation methodology are quoted prices in markets that are not considered to be active, or financial instruments without quoted market prices, but for which all significant inputs are observable, either directly or indirectly.

Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

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.

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, 2014 and 2013.

Registered investment companies (mutual funds) – Valued at the net asset value (NAV) of shares held by the plan at year end using prices quoted by the relevant pricing agent.

Registered investment companies (money market fund) – The money market fund is valued using the NAV of the money market as reported by the money market managers. 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 NAV of a money market is calculated based on a compilation of primarily observable market information.

The money market fund invests 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 fund has no redemption features or restrictions.

Common stocks – 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.

UMPQUA BANK 401(k) AND PROFIT SHARING PLAN

NOTES TO FINANCIAL STATEMENTS

Note 4 – Fair Value Measurements (continued)

Collective trust – Units held in the collectivetrust are valued using the NAV of the fund. 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. The NAV of a collective investment is calculated based on a compilation of primarily observable market information. The number of units of the trust that are outstanding on the calculation date is derived from observable purchase and redemption activity in the trust. Accordingly, the unit value for a collective investment is classified within level 2 of the valuation hierarchy.

The Wells Fargo Stable Value Fund C (the Fund) is a collective trust designed to provide preservation of capital and returns that are consistent regardless of stock and bond market volatility. The Fund seeks to earn a high level of income consistent with those objectives. The Fund invests 100% in the Wells Fargo Stable Return Fund G which holds guaranteed investment contracts and security-backed contracts, both of which typically have a fixed maturity. Each contract contains a provision that the issuer will, if required, repay principal at the stated contract value for the purpose of paying benefit payments (fully benefit-responsive).

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.

The following tables summarize investments classified within level 2 of the valuation hierarchy and measured at fair value based upon NAV per share as of December 31:

Note 5 – Tax Status

The Internal Revenue Service has determined and informed the Company by a letter dated May 20, 2014, 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, 2014 and 2013 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 6 – 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 7 – Party-in-Interest Transactions

Plan investments include shares of the Umpqua Holdings Corporation Stock which is comprised of common stock of the Company.

Note 8 – 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 9 - Transfer of Assets

During 2014, the Plan had an increase in net assets of $117.6 million as a result of the transfer of assets from other plans.

Effective April 18, 2014, the Company merged with Sterling Financial Corporation and subsidiaries (Sterling). This resulted in approximately 2,300 new plan participants. In July 2014, the assets of the Sterling Savings Bank Employee Savings and Investment Plan and Trust were transferred into the Plan, an increase of $109.9 million to plan assets.

Effective July 1, 2013, the Company acquired Financial Pacific Holding Corporation and subsidiaries (FinPac), which added approximately 125 employees to the Plan. During 2014, the assets of Financial Pacific's plan were transfered into the Plan, an increase of $7.7 million to plan assets.
