Banner Corporation Earns $45.2 million, or $1.89 per diluted share, in 2015;

Includes $6.9 Million, or $0.20 Per Diluted Share, in the Fourth Quarter of 2015;

Fourth Quarter Highlighted By Completed Acquisition of AmericanWest Bank

Walla Walla, WA - January 27, 2016 - Banner Corporation (NASDAQ GSM: BANR), the parent company of Banner Bank and Islanders Bank, today reported net income in the fourth quarter of 2015 of $6.9 million, or $0.20 per diluted share, compared to $12.9 million, or $0.62 per diluted share, in the preceding quarter and $11.7 million, or $0.60 per diluted share, in the fourth quarter a year ago.  The current quarter results were impacted by $18.4 million of acquisition-related expenses which, net of tax benefit, reduced net income by $0.37 per diluted share, and the preceding quarter results were impacted by $2.2 million of acquisition-related expenses which, net of tax benefit, reduced net income by $0.09 per diluted share.

For the year, net income was $45.2 million, or $1.89 per diluted share, compared to $54.1 million, or $2.79 per diluted share, in 2014.  Results for 2014 included a $9.1 million bargain purchase gain related to the acquisition of six branches in southwest Oregon, which net of taxes contributed $0.30 to diluted net income per share.  Acquisition-related expenses were $26.1 million, or $0.76 per diluted share net of tax benefit, in 2015 compared to $4.3 million, or $0.17 per diluted share net of tax benefit, in 2014.

“For Banner Corporation 2015 was a truly transformational year,” stated Mark J. Grescovich, President and Chief Executive Officer.  “While our operating results for the most recent quarter and full year continued to reflect the success of our proven client acquisition strategies, which produced strong organic growth of loans and deposits, as well as core revenues, we also benefited meaningfully from the successful acquisition and integration of Siuslaw Bank in March 2015 and the six branches in southwest Oregon that we acquired in June 2014.  In addition, the recently completed acquisition of AmericanWest Bank had a dramatic impact on our operating results for the fourth quarter of 2015, substantially increasing the scale and reach of the Company and providing tremendous opportunity for future revenue growth.  With this strategic combination, we will deploy our super community bank model throughout a strengthened presence in Washington, Oregon and Idaho, and enter attractive growth markets in California and Utah.  Although there remains significant additional work to be done to complete the full integration of the two companies and realize the expected operating synergies, we are exceptionally pleased with the progress we have made through the dedicated efforts of our employees and expect that, similar to the prior acquisitions, this acquisition of AmericanWest Bank will result in significant benefits to our expanding group of clients, communities, employees and shareholders.”

With the completion of the AmericanWest Bank acquisition, at December 31, 2015 Banner Corporation had $9.8 billion in assets, $7.2 billion in net loans and $8.1 billion in deposits.  As Banner Bank deploys its super community bank business model across five western states, the combined bank, with 202 branch offices located in nine of the top 20 largest western Metropolitan Statistical Areas by population, is benefiting from its diversified geographic footprint with significant growth opportunities.

Acquisition of AmericanWest Bank

Effective October 1, 2015, Banner completed the acquisition of Starbuck Bancshares, Inc. ("Starbuck") and its wholly owned subsidiary AmericanWest Bank.  The merger was accounted for using the acquisition method of accounting.  Accordingly, the purchase price was allocated to the assets (including identifiable intangible assets) and the liabilities of Starbuck at their respective estimated fair values as of the merger date.  The excess of the purchase price over the fair value of the net assets acquired was allocated to goodwill.  The fair value on the merger date represents management's best estimates based on available information and facts and circumstances in existence on the merger date.  The allocation of the purchase price is subject to adjustment within the measurement period.

In addition to the acquisition of AmericanWest Bank, the acquisition of Siuslaw Financial Group and its wholly-owned subsidiary Siuslaw Bank ("Siuslaw") in March 2015 and acquisition of six branches in southwest Oregon acquired in June 2014 (the (the "Branch purchase") had a significant impact on the current and historical operating results of Banner.  For additional details regarding these acquisitions and merger related expenses, see the tables under Business Combinations on pages 12 and 13 of this press release.

Income Statement Review

Banner’s fourth quarter net interest income, before the provision for loan losses, increased 76% to $92.1 million, compared to $52.2 million in the preceding quarter and increased 97% compared to $46.7 million in the fourth quarter a year ago, largely reflecting the acquisitions of AmericanWest Bank and Siuslaw and continued client acquisition.  In 2015, Banner’s net interest income increased 35% to $242.3 million compared to $179.9 million in 2014, which in addition to the acquisitions reflected the Branch purchase and significant organic loan and deposit growth.

“Although lower as expected following the acquisition of AmericanWest Bank, we maintained a solid net interest margin in the fourth quarter reflecting a strong loan to deposit ratio and well disciplined pricing decisions,” said Grescovich.  Net interest margin is enhanced by the amortization of acquisition accounting discounts on purchased loans received in Banner's acquisitions, which is accreted into loan interest income, as well as by net premiums on non-market-rate certificate of deposit liabilities assumed which are amortized as a reduction to deposit interest expense.  The preceding quarter was impacted by the accretion of acquisition accounting loan discounts from the Siuslaw acquisition and immaterial amount of deposit premium amortization which together contributed approximately three basis points to the margin in that period.  Banner's net interest margin was 4.05% for the fourth quarter of 2015, which included 11 basis points as a result of accretion from acquisition accounting loan discounts from both the AmericanWest Bank and Siuslaw acquisitions and three basis points from the amortization of deposit premiums, compared to 4.14% in the preceding quarter and 4.08% in the fourth quarter a year ago.  For the year, Banner’s net interest margin was 4.10%, which included seven basis points from acquisition accounting adjustments, compared to 4.07% in 2014, which included just one basis point from acquisition accounting adjustments.

Average interest-earning asset yields decreased ten basis points compared to the preceding quarter and decreased seven basis points from the fourth quarter a year ago.  Despite the positive impact from the accretion of discounts on the loans acquired through the acquisitions, which added

January 27, 2016

Page 3

14 basis points to reported yields for the quarter, loan yields decreased four basis points compared to the preceding quarter and decreased eight basis points from the fourth quarter a year ago.  The decrease in the average loan yield was primarily attributable to changes in the portfolio mix as a result of the acquisitions, as well as payoffs of loans which had a higher yield than the average yield of newly originated loans.  Deposit costs decreased one basis point compared to the preceding quarter and decreased three basis points compared to the fourth quarter a year ago.  Amortization of acquisition accounting net premiums on certificates of deposit reduced the cost of deposits by three basis points in the fourth quarter 2015 and by one basis point for the full year.  The total cost of funds declined two basis points in the fourth quarter compared to the preceding quarter and declined five basis points compared to the fourth quarter a year ago.

“Home purchase activity remains robust in our markets, and revenues from mortgage banking remained strong, reflecting Banner’s increased market presence and our investment in this business line,” said Grescovich.  Mortgage banking operations contributed $4.5 million to fourth quarter revenues compared to $4.4 million in the preceding quarter and $3.0 million in the fourth quarter of 2014.  In 2015, mortgage banking operations produced $17.7 million of revenues compared to $10.2 million in 2014.  Home purchase activity accounted for 61% of fourth quarter mortgage banking originations and 63% of mortgage originations in 2015.

Deposit fees and other service charges increased 35% to $13.2 million in the fourth quarter of 2015, compared to $9.7 million in the preceding quarter and increased 58% compared to $8.3 million in the fourth quarter a year ago.  In 2015, deposit fees and other service charges increased 33% to $40.6 million compared to $30.6 million in 2014.  The year-over-year increase reflects strong organic growth, as well as the AmericanWest Bank and Siuslaw acquisitions and the Branch purchase, together resulting in significant growth in the number of deposit accounts and increased transaction activity.

Revenues from core operations* (revenues excluding gains and losses on the sale of securities, net change in valuation of financial instruments and the bargain purchase gain) increased 66% to $112.0 million in the fourth quarter ended December 31, 2015, compared to $67.4 million in the preceding quarter and increased 90% compared to $59.1 million in the fourth quarter of 2014.  In 2015, revenues from core operations* increased 36% to $305.9 million, compared to $224.4 million in 2014.  Total revenues were $110.5 million for the quarter ended December 31, 2015, compared to $66.3 million in the preceding quarter and $58.8 million in the fourth quarter a year ago.  In 2015, total revenues were $304.6 million, compared to $234.9 million in 2014.

Banner’s fourth quarter 2015 results included a $1.5 million net loss for fair value adjustments as a result of changes in the valuation of financial instruments carried at fair value, as well as a $3,000 net loss on the sale of securities.  In the preceding quarter, results included a $1.1 million net loss for fair value adjustments and in the fourth quarter a year ago results included a $287,000 net loss for fair value adjustments, as well as a $1,000 gain on the sale of securities.

Banner’s total other operating income, which includes the changes in the valuation of financial instruments and gains and losses on the sale of securities, was $18.4 million in the fourth quarter of 2015, compared to $14.1 million in the third quarter of 2015 and $12.1 million in the fourth quarter a year ago.  For the full year, total other operating income was $62.3 million compared to $55.0 million in 2014 which also included the $9.1 million bargain purchase gain from the Branch purchase.  Other operating income from core operations,* which excludes gains and losses on sale of securities and net changes in the valuation of financial instruments, was $19.9 million for the fourth quarter of 2015, compared to $15.2 million for the preceding quarter and $12.4 million for the fourth quarter a year ago.  For the year, other operating income from core operations* increased 43% to $63.6 million, compared to $44.5 million in 2014.

Total other operating expenses (non-interest expenses) were $100.3 million in the fourth quarter of 2015, compared to $46.7 million in the preceding quarter and $41.2 million in the fourth quarter of 2014.  The year-over-year increase in operating expenses was largely attributable to acquisition-related expenses and incremental costs associated with operating the 98 branches acquired in the AmericanWest Bank acquisition on October 1, 2015 and the ten Siuslaw branches acquired in March 2015, as well as generally increased compensation, occupancy and payment and card processing services reflecting increased transaction volume.  There were $18.4 million in acquisition-related expenses in the current quarter compared to $2.2 million in the preceding quarter and $2.8 million in the fourth quarter a year ago.  For the year, total other operating expenses were $236.6 million, compared to $153.7 million in 2014, with acquisition-related expenses of $26.1 million, compared to $4.3 million in 2014.  Acquisition-related expenses in the year ended December 31, 2015 included $24.1 million related to the acquisition of AmericanWest Bank and $2.0 million related to the acquisition of Siuslaw.  In addition to the AmericanWest Bank and Siuslaw branches, the increase in total operating expenses for the full year reflects costs associated with operating the six southwest Oregon branches acquired in June 2014.

For the fourth quarter of 2015, Banner recorded $3.3 million in state and federal income tax expense for an effective tax rate of 32.4%, which reflects normal marginal tax rates increased by the effect of certain non-deductible merger expenses and reduced by the effect of tax-exempt income and certain tax credits.

Balance Sheet Review

Largely as a result of the AmericanWest Bank acquisition, but also reflecting organic growth, total assets increased by 87% to $9.80 billion at December 31, 2015, compared to $5.31 billion at September 30, 2015, and increased 107% compared to $4.72 billion a year ago.  The total of

securities and interest-bearing deposits held at other banks was $1.54 billion at December 31, 2015, compared to $648.5 million at September 30, 2015 and $637.5 million a year ago.  The increase in securities portfolio is primarily a result of positions held by AmericanWest at the time of the merger.  The average effective duration of Banner's securities portfolio was approximately 3.3 years at December 31, 2015.

“Net loans increased by $2.94 billion, or 69%, during the quarter and increased 93% year-over-year due to both the AmericanWest Bank and Siuslaw acquisitions and strong organic growth.  Loan production remained solid, as did the regional economy, and we continue to see significant potential for growth in our loan origination pipelines,” added Grescovich.

Net loans were $7.24 billion at December 31, 2015, compared to $4.29 billion at September 30, 2015, and $3.76 billion a year ago.  The AmericanWest Bank acquisition accounted for $2.82 billion of the year-end loan portfolio and the Siuslaw acquisition accounted for $236 million, of the year-end loan portfolio.  Commercial real estate and multifamily real estate loans increased 88% to $3.57 billion at December 31, 2015, compared to $1.90 billion at September 30, 2015, and increased 127% compared to $1.57 billion a year ago.  Commercial business loans increased 49% to $1.21 billion at December 31, 2015, compared to $812.1 million three months earlier and increased 67% compared to $724.0 million a year ago.  Agricultural business loans increased 55% to $376.5 million at December 31, 2015, compared to $242.6 million three months earlier and increased 58% compared to $238.5 million a year ago.  Total construction, land and land development loans increased 16% to $574.2 million at December 31, 2015, compared to $493.8 million at September 30, 2015, and increased 40% compared to $411.0 million a year earlier.

Banner’s total deposits increased 84% to $8.06 billion at December 31, 2015, compared to $4.39 billion at September 30, 2015 and increased 107% compared to $3.90 billion a year ago.  The AmericanWest Bank acquisition accounted for $3.54 billion and the Siuslaw acquisition accounted for  $336 million, respectively, of the deposit portfolio at December 31, 2015.  Non-interest-bearing account balances increased 68% to $2.62 billion at December 31, 2015, compared to $1.56 billion three months earlier and increased 102% compared to $1.30 billion a year ago.  Interest-bearing transaction and savings accounts increased 94% to $4.07 billion at December 31, 2015, compared to $2.10 billion three months earlier and increased 122% compared to $1.83 billion a year ago.  Certificates of deposit increased 87% to $1.37 billion at December 31, 2015, compared to $730.7 million at September 30, 2015, and increased 77% compared to $770.5 million a year earlier.  Brokered deposits totaled $162.9 million at December 31, 2015, compared to $10.1 million at September 30, 2015 and $4.8 million a year ago.

Banner’s core deposits represented 83% of total deposits at December 31, 2015, compared to 80% of total deposits a year earlier.  The cost of deposits was 0.15% for the quarter ended December 31, 2015, compared to 0.16% in the preceding quarter, and declined two basis points from 0.18% for the quarter ended December 31, 2014.

At December 31, 2015, total common stockholders' equity was $1.30 billion, or $37.97 per share, compared to $671.2 million at September 30, 2015 and $582.9 million a year ago.  This increase was mostly due to 13.23 million shares of common stock and non-voting common stock issued on October 1, 2015 in connection with the AmericanWest Bank acquisition, which were valued at $47.67 per share and increased stockholders’ equity by $630.7 million.  In addition, on March 6, 2015, Banner issued 1.3 million shares in connection with the Siuslaw acquisition, which were valued at $44.02 per share and added $58.1 million to stockholders’ equity.  At December 31, 2015, tangible common stockholders' equity*, which excludes goodwill and other intangible assets, was $1.02 billion, or 10.68% of tangible assets*, compared to $644.6 million, or 12.20% of tangible assets, at September 30, 2015, and $580.1 million, or 12.29% of tangible assets, a year ago.  Banner's tangible book value per share* increased slightly to $29.66 at December 31, 2015, compared to $29.64 per share a year ago.

Banner Corporation and its subsidiary banks continue to maintain capital levels in excess of the requirements to be categorized as “well-capitalized” under the newly implemented Basel III and Dodd Frank regulatory standards.  At December 31, 2015, Banner Corporation's common equity Tier 1 capital ratio was 12.15%, its Tier 1 leverage capital to average assets ratio was 11.06% and its total capital to risk-weighted assets ratio was 13.66%.

Credit Quality

“No provision for loan losses was required during the current quarter or the full year despite the organic loan growth,” said Grescovich.  “Our credit quality metrics continue to reflect our moderate risk profile and our reserve levels remain strong.”

In accordance with acquisition accounting, loans acquired from AmericanWest Bank and Siuslaw were recorded at their estimated fair value, which resulted in a net discount to the loans’ contractual amounts, of which a portion reflects a discount for possible credit losses.  Credit discounts are included in the determination of fair value and as a result no allowance for loan and lease losses is recorded for acquired loans at the acquisition date.  Although the discount recorded on the acquired loans is not reflected in the allowance for loan losses, or related allowance coverage ratios, we believe it should be considered when comparing the current ratios to similar ratios in periods prior to the acquisitions of AmericanWest Bank and Siuslaw.

The allowance for loan losses was $78.0 million at December 31, 2015, or 1.07% of total loans outstanding and 512% of non-performing loans compared to $76.0 million at December 31, 2014, or 1.98% of total loans outstanding.  Banner had net recoveries of $688,000 in the fourth quarter compared to net charge-offs of $9,000 in the third quarter of 2015 and net recoveries of $1.6 million in the fourth quarter a year ago.  If the allowance for loan losses and loans were grossed up for the remaining loan discount the adjusted allowance for loans to adjusted loans would

have been 1.67% as of December 31, 2015.  Non-performing loans were $15.2 million at December 31, 2015, compared to $16.0 million at September 30, 2015, and $16.7 million a year ago.  Real estate owned and other repossessed assets increased to $11.6 million at December 31, 2015, compared to $6.4 million at September 30, 2015 and $3.4 million a year ago primarily due to additional real estate owned acquired in the mergers.

Banner's non-performing assets were 0.28% of total assets at December 31, 2015, compared to 0.42% at September 30, 2015 and 0.43% a year ago.  Non-performing assets were $27.1 million at December 31, 2015, compared to $22.4 million at September 30, 2015 and $20.2 million a year ago.  In addition to non-performing assets, purchase credit impaired loans increased to $58.6 million at December 31, 2015 compared to $5.4 million at September 30, 2015 as a result of the acquisition of AmericanWest Bank.
