Exhibit 99.1

Great Western Bancorp, Inc. Announces Fiscal Year 2015 Fourth Quarter Financial Results; Sets Annual Stockholder Meeting Date

Highlights for the Fourth Quarter of Fiscal Year 2015

• Fourth quarter net income was $33.8 million, or $0.60 per share, bringing net income for fiscal year 2015 to $109.1 million, or $1.90 per share

• Net interest margin and adjusted net interest margin¹ each increased compared to the previous quarter to 3.98% and 3.72%, respectively

• Net charge-offs during the quarter were minimal at $0.4 million or 0.02% of average loans on an annualized basis

• The efficiency ratio¹ for the quarter was 45.8%, favorable compared to the previous quarter primarily due to a decrease in tangible noninterest expense¹ 

• Total loans grew $80.0 million during the quarter and $537.7 million, or 7.9%, during fiscal year 2015

• Modest deposit growth during the quarter contributed to 4.7% deposit growth for fiscal year 2015, including $367 million of net growth in business deposits, reflecting a focus on this important funding source

• National Australia Bank, Ltd. ("NAB") completed its planned divestiture of 100% of Great Western Bancorp, Inc. ("GWB")

• GWB completed a private placement of $35 million of subordinated notes, repaid all outstanding borrowings due to NAB and repurchased $60 million of common stock from NAB in conjunction with the final secondary offering of NAB's shares of GWB

Sioux Falls, SD - October 29, 2015 - Great Western Bancorp, Inc. (NYSE: GWB) today reported net income of $33.8 million, or $0.60 per share, for the quarter ended September 30, 2015, compared to net income of $27.9 million, or $0.48 per share, for the same quarter of fiscal year 2014. The results for the quarter included a $1.7 million nonrecurring item related to the resolution of a deferred tax item, which contributed approximately $0.03 per share after tax. Net interest income, noninterest income, noninterest expense and provision for loan losses each improved compared to the same quarter in fiscal year 2014. Net income for fiscal year 2015 was $109.1 million, or $1.90 per share, compared to $105.0 million, or $1.81 per share, for fiscal year 2014.

"I am very proud of everything we accomplished during the September quarter and in fiscal year 2015," said Ken Karels, President and Chief Executive Officer. "We again delivered year-over-year revenue and net income growth, despite the challenging low-rate environment. We successfully completed NAB's divestiture of their stake in GWB and executed other capital-related transactions that we believe will generate favorable returns for our new public stockholder base. We look forward to fiscal year 2016 as an independent, publicly-traded company with great momentum and a positive outlook on the year to come."

Net Interest Income and Net Interest Margin² 

Net interest income was $87.2 million for the fourth quarter of fiscal year 2015, an increase of $2.7 million, or 3%, compared to the same quarter in fiscal year 2014. The increase was driven by higher loan interest income attributable to loan growth and lower deposit interest expense resulting from a lower cost of deposits, partially offset by a 3% decline in interest income from the investment portfolio attributable to a contraction in portfolio yield.

Net interest margin was 3.98%, 3.95% and 4.10%, respectively, for the quarters ended September 30, 2015, June 30, 2015 and September 30, 2014 and 3.94% and 4.02%, respectively, for the twelve months ended September 30, 2015 and September 30, 2014. Adjusted net interest margin¹, which adjusts for the realized gain (loss) on interest rate swaps, was 3.72%, 3.70% and 3.86%, respectively, and 3.68% and 3.79%, respectively, for the same periods.

Net interest margin and adjusted net interest margin¹ declined compared to the fourth quarter of fiscal year 2014 primarily due to a lower loan yield, partially offset by a continued reduction in the cost of deposits and a change in the mix of interest earning

¹ This is a non-GAAP measure management believes is helpful to understanding trends in the business that may not be fully apparent based only on the most comparable GAAP measure. Further information on this measure and a reconciliation to the most comparable GAAP measure is provided at the end of this release.

² All references to net interest income and net interest margin are presented on a fully-tax equivalent basis unless otherwise noted.

assets away from investments and into loans. The yield on loans, excluding loans acquired with deteriorated credit quality, was 29 basis points lower in the fourth quarter of fiscal year 2015 compared to the same quarter in fiscal year 2014, while the investment portfolio yield decreased by 6 basis points over the same period. Total cost of deposits decreased by 5 basis points. Compared to the quarter ended June 30, 2015, net interest margin and adjusted net interest margin¹ increased by 3 basis points and 2 basis points, respectively, driven by loan growth contributing to a change in asset mix.

Loan growth for the quarter ended September 30, 2015 was $80.0 million, bringing loan growth for the full fiscal year to $537.7 million, an increase of 7.9% compared to September 30, 2014. Net of the decline in loan balances managed by the Company's loan workout group, core loan growth for the fiscal year was $599.8 million, or 9.2%. Year-to-date growth was strongest in the commercial real estate (i.e., CRE, 12% annual growth) and agriculture (11%) segments of the portfolio, while commercial non-real estate (i.e., C&I) loans grew 3%, impacted by a small number of payoffs received during the final quarter of the fiscal year. CRE loan growth was driven primarily by renewed demand for CRE investment in the larger markets the Company serves, while agriculture growth was predominantly within the protein sub-segment, and specifically beef and dairy producers. Overall, loan growth was focused on the commercial and agriculture segments of the portfolio, in line with strategy.

Total deposits grew by $29.4 million during the quarter and by $334.9 million, or 4.7%, for fiscal year 2015. Deposit growth was focused primarily within interest-bearing non-time accounts, partially offset by a continued decline in time deposits, and included $367 million of net growth in business deposits, reflecting a continued focus on this area of the business. The carrying value of the investment portfolio declined by $83.1 million during the quarter as a result of security sales and normal principal payments received, with the net proceeds increasing cash balances and allowing for a 2% reduction in outstanding FHLB borrowings. The average cost of deposits for the quarter was 0.30%, down 5 basis points compared to the same quarter in fiscal year 2014 and down 1 basis point compared to the quarter ended June 30, 2015.

Provision for Loan Losses and Asset Quality

Provision for loan losses was $1.6 million for the quarter ended September 30, 2015, compared to $2.7 million in the same quarter of fiscal year 2014, and was $19.0 million for fiscal year 2015, compared to $0.7 million for fiscal year 2014. Net charge-offs for the quarter were $0.4 million, or 0.02% of total loans on an annualized basis, bringing fiscal year-to-date net charge-offs to $9.4 million, or 0.13% of total loans on an annualized basis. For the comparable periods in fiscal year 2014, net charge-offs were $2.3 million, or 0.13% of total loans on an annualized basis, and $9.0 million, or 0.14% of loans on an annualized basis, respectively. The ratio of allowance for loan losses ("ALLL") to total loans was 0.78% at September 30, 2015, up from 0.77% at June 30, 2015 and 0.70% at September 30, 2014. Both the specific and general portions of the ALLL increased during the fiscal year with a portion of the growth in the general ALLL attributable to net loan growth.

At September 30, 2015, nonperforming loans were $68.3 million, with $5.3 million of the balance covered by FDIC loss-sharing arrangements. Total nonperforming loans increased by $0.2 million during the quarter. Total OREO balances were $15.9 million as of September 30, 2015, a decrease of $6.1 million, or 28%, compared to June 30, 2015 and a decrease of $33.7 million, or 68%, compared to September 30, 2014. Loans on "Watch" status were $310.4 million at September 30, 2015, a decrease of $11.9 million, or 4%, during the quarter.

Crop conditions across the Company's core grain lending footprint of South Dakota, Nebraska and Iowa appear favorable. According to a United States Department of Agriculture ("USDA") report released October 5, 2015, the percentage of the corn crop rated Fair, Good or Excellent was 96% for South Dakota, 93% for Nebraska and 96% for Iowa, while the same metrics for soybeans were 97%, 94% and 95%, respectively. Commodity prices, borrower-specific conditions and borrowers' financial management will all contribute to credit outcomes for the 2015 growing season for the Company's agriculture borrowers, however, management believes that favorable overall crop conditions and higher expected yields should partially offset the impact of lower commodity prices.

Total credit-related charges declined compared to the previous quarter, but increased significantly for fiscal year 2015 compared to fiscal year 2014. A summary of total credit-related charges incurred during the current, prior and comparable quarters and current and prior fiscal years is presented below:

Noninterest Income³ 

Noninterest income was $9.0 million for the quarter ended September 30, 2015, an increase of $0.5 million, or 6%, compared to the fourth quarter of fiscal year 2014. Included within noninterest income are the changes in fair value of certain loans for which the Company has elected the fair value option and the net gain (loss), realized and unrealized, of the related derivatives used to manage the interest rate risk on these loans. On a net basis, these two components of noninterest income accounted for an increase of $0.5 million. Deposit service charges and other fees declined by $0.2 million, or 2%, compared to the same quarter in fiscal year 2014, driven by a reduction in net consumer overdraft and non-sufficient funds revenue, partially offset by increased fee income related to commercial deposit accounts. Sales of investment securities generated net gains of $0.3 million during the quarter.

Noninterest Expense³ 

Total noninterest expense was $44.8 million for the quarter ended September 30, 2015, a decrease of $3.5 million, or 7%, compared to the same quarter in fiscal year 2014. The decrease in noninterest expense was primarily driven by:

• a $2.2 million reduction in other noninterest expense, which reflects the difference in costs related to branch closures and gain or loss on sale of closed branch locations;

• a $2.1 million reduction in scheduled amortization of intangible assets; and

• a $0.5 million reduction in net OREO costs;

partially offset by:

• a $1.3 million increase in salaries and employee benefits driven by incremental roles hired over the course of the fiscal year to support growth and public company requirements and higher health insurance costs; and

• a $1.0 million increase in professional fees largely attributable to the timing of costs incurred related to the Company's initial public offering in 2014.

The efficiency ratio¹ was 45.8% for the quarter, compared to 49.0% for the same quarter of fiscal year 2014, and was 48.0% for fiscal year 2015, compared to 50.4% for fiscal year 2014.

Capital

During the quarter, the Company completed three specific capital transactions in addition to NAB's secondary offering. In conjunction with NAB's final secondary offering of GWB stock, the Company completed a share repurchase of 2.67 million shares ($60 million aggregate) directly from NAB, resulting in a reduction of approximately 80 basis points of total capital. On the same date, the Company completed a private placement of $35 million aggregate principal amount of subordinated notes due August 2025, bearing interest for the first five years at a fixed rate of 4.875%. The notes qualify as tier 2 capital. Finally,

³ The Company made two minor presentation changes on the income statement in the current quarter. Within Noninterest income, Casualty insurance commissions, Investment center income and Trust department income are now grouped and presented as Wealth management fees consistent with how those lines of business are managed. Within Noninterest expense, the Company previously presented (Gain)/loss on sale of repossessed property and other assets separately and presented the related OREO carrying costs and valuation adjustments within Other noninterest expense. Going forward, all OREO-related costs are presented within Net loss (recovery) on repossessed property and other related expenses to improve the visibility of these costs.

Exhibit 99.1

the Company utilized the proceeds of the private placement of subordinated notes and other cash on hand to repay NAB $35.8 million of outstanding subordinated debt and $5.5 million outstanding on a revolving line of credit. The NAB subordinated debt was subject to a haircut for regulatory capital purposes and its repayment reduced tier 2 capital by $14.3 million. Following these transactions, the Company has no other outstanding indebtedness due to NAB or any of its subsidiaries.

Tier 1 and total capital ratios were 10.9% and 12.1%, respectively, as of September 30, 2015, compared to 11.5% and 12.5%, respectively, as of June 30, 2015. The common equity tier 1 capital ratio was 10.1% as of September 30, 2015 and 10.8% as of June 30, 2015. The tier 1 leverage ratio was 9.1% as of September 30, 2015 and 9.4% as of June 30, 2015. All regulatory capital ratios remain above regulatory minimums to be considered "well capitalized."

On October 28, 2015, the Company’s board of directors declared a dividend of $0.14 per common share payable on November 30, 2015 to owners of record as of close of business on November 13, 2015. The aggregate dividend payment will be $7.7 million.

Business Outlook

"We are optimistic as we look forward to fiscal year 2016," added Karels. "We are committed to delivering strong profitability once again while continuing to grow and improve the Great Western Bank brand. We expect to continue to refine our branch footprint to drive growth and most effectively allocate our resources and, most importantly, we will strive each day to Make Life Great for our customers and employees, ultimately leading to the best possible return for our shareholders."

Non-GAAP Measures and Reconciliation

We rely on certain non-GAAP measures in making financial and operational decisions about our business. We believe that each of the non-GAAP measures presented is helpful in highlighting trends in our business, financial condition and results of operations which might not otherwise be apparent when relying solely on our financial results calculated in accordance with U.S. generally accepted accounting principles, or GAAP.

In particular, we evaluate our profitability and performance based on our cash net income and return on average tangible common equity, each of which excludes the effects of amortization expense relating to intangible assets and related tax effects from the acquisition of us by National Australia Bank Limited and our acquisitions of other institutions. We believe these measures help highlight trends associated with our financial condition and results of operations by providing net income and return information based on our cash payments and receipts during the applicable period.

We also evaluate our profitability and performance based on our adjusted net interest income, adjusted net interest margin, adjusted interest income on loans other than loans acquired with deteriorated credit quality and adjusted yield on loans other

Exhibit 99.1

than loans acquired with deteriorated credit quality. We adjust each of these four measures to include the current realized gain (loss) of derivatives we use to manage interest rate risk on certain of our loans, which we believe economically offsets the interest income earned on the loans. Similarly, we evaluate our operational efficiency based on our efficiency ratio, which excludes the effect of amortization of core deposit and other intangibles (a non-cash expense item) and includes the tax benefit associated with our tax-advantaged loans.

We evaluate our financial condition based on the ratio of our tangible common equity to our tangible assets. Our calculation of this ratio excludes the effect of our goodwill and other intangible assets. We believe this measure is helpful in highlighting the common equity component of our capital and because of its focus by federal bank regulators when reviewing the health and strength of financial institutions in recent years and when considering regulatory approvals for certain actions, including capital actions.

Reconciliations for each of these non-GAAP financial measures to the closest GAAP financial measures are included in the tables below. Each of the non-GAAP measures presented should be considered in context with our GAAP financial results included in this release.
