Sioux Falls, SD - October 26, 2017 - Great Western Bancorp, Inc. (NYSE: GWB) today reported net income of $37.7 million, or $0.64 per diluted share, for the fourth quarter of fiscal year 2017, compared to net income of $35.1 million, or $0.59 per diluted share, for the third quarter of fiscal year 2017. Net income for fiscal year 2017 was $144.8 million, or $2.45 per diluted share, compared to $121.3 million, or $2.14 per diluted share, for fiscal year 2016.

"I am glad to report today that we continued our long-standing trend of growing annual net income and earnings per share again in fiscal year 2017," said Ken Karels, Chairman, President and Chief Executive Officer. "We were able to deliver significant year-over-year growth including a 19.4% increase in net income, a 14.5% increase in diluted earnings per share and 10.0% increase in tangible book value per share while maintaining a peer-leading efficiency ratio. These financial outcomes are the result of the hard work of all of our employees to do what is right for our customers and the organization and I want to thank everyone for that hard work and dedication throughout the year."

Net Interest Income and Net Interest Margin²

Net interest income was $103.7 million for the fourth quarter of fiscal year 2017, compared to $100.9 million, an increase of $2.8 million, or 2.8%. The increase was primarily attributable to higher loan interest income driven by growth of 1.9% in average loans outstanding between the periods combined with a 7 basis point increase in the yield on total loans, partially offset by a 5 basis point increase in the cost of deposits. The yield on non-ASC 310-30 loans increased by 4 basis points between the two periods, while the yield on ASC 310-30 loans, which are purchased credit impaired loans with a different income recognition model, increased as a result of accelerated accretion on an acquired loan pool.

Net interest margin was 4.00% for each of the quarters ended September 30, 2017 and June 30, 2017. Adjusted net interest margin¹, which adjusts for the realized gain (loss) on interest rate swaps, was 3.90% and 3.87%, respectively, for the same periods, representing a 3 basis point increase. Net interest margin remained stable primarily due to a 6 basis point rise in the yield on interest-earning assets, offset by a 6 basis point rise in the cost of interest-bearing liabilities. The growth in the adjusted net interest margin¹was driven by a reduction in the cost of interest rate swaps of $0.6 million, as a result of increases in short-term LIBOR rates.

Total loan growth during the fourth quarter of fiscal year 2017 was $176.7 million, or 2.0%. The net growth during the quarter was primarily driven by $159.2 million of commercial real estate ("CRE") loan growth and $35.0 million of agriculture loan growth, partially offset by a $20.4 million reduction in residential real estate loans outstanding.

Total loans increased by $285.9 million compared to September 30, 2016. Loan growth for the year was impacted by a $64.3 million reduction to the fair value of the $1.02 billion segment of the loan portfolio carried at fair value resulting from changes in market interest rates, which primarily occurred in our first fiscal quarter. Aside from this change, which was offset by the changes in the fair value of the related derivatives hedging the interest rate risk in this portfolio, and which had no impact to net income, customer loan balances increased by $350.2 million, or 4.1%.

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.

Exhibit 99.1

Total deposits were $8.98 billion as of September 30, 2017, a slight increase over the quarter, bringing deposit growth for the full year to $372.8 million, or 4.3%. Noninterest-bearing deposits were $1.86 billion, a 3.1% reduction, for the quarter and interest-bearing deposits were $7.12 billion, a 1.1% increase for the quarter. FHLB and other borrowings increased by $172.5 million, or 36.6%, as a result of loan growth during the quarter exceeding net deposit growth.

Provision for Loan and Lease Losses and Asset Quality

Provision for loan and lease losses was $4.7 million for the fourth quarter of fiscal year 2017, a decrease of $1.1 million, or 19.2%. Net charge-offs for the fourth quarter were $5.4 million, or 24 basis points of average total loans on an annualized basis, an increase of $1.1 million, or 4 basis points of average total loans on an annualized basis. The higher level of net charge-offs recognized during the fourth quarter were concentrated in the commercial and industrial ("C&I") segment of the loan portfolio. The majority of the increase was driven by charge-offs related to loans for which a specific allowance for loan and lease loss had previously been recorded. The ratio of allowance for loan and lease losses ("ALLL") to total loans was 0.71% at September 30, 2017, a decrease from 0.73%. The balance of the ALLL decreased to $63.5 million from $64.2 million.

Included within total loans are approximately $1.02 billion of loans for which management has elected the fair value option. These loans are excluded from the ALLL process, but management has estimated that $8.3 million of the fair value adjustment for these loans relates to credit risk, or 0.09% of total loans. Finally, total purchase discount remaining on all acquired loans equates to 0.32% of total loans.

At September 30, 2017, loans graded "Watch" were $311.6 million, an increase of $12.6 million, or 4.2%, and loans graded "Substandard" were $232.8 million, a decrease of $17.8 million, or 7.1%.

Nonaccrual loans were $138.3 million as of September 30, 2017, with $4.9 million of the balance covered by FDIC loss-sharing agreements. Total nonaccrual loans increased by $14.7 million during the quarter. The increase in nonaccrual loans during the quarter was primarily driven by the deterioration of a small number of relationships that have been closely monitored for a number of quarters. Total OREO balances were $9.0 million as of September 30, 2017, a decrease of $0.1 million, or 0.7%.

Total credit-related charges for the current quarter increased $0.9 million compared to the third quarter of fiscal year 2017 and increased $3.9 million for the current year compared to fiscal year 2016. The year-over-year increase in total credit-related charges was primarily driven by increased net charge-offs driving higher required provision for loan and lease losses. A summary of total credit-related charges incurred during the current and prior quarters and fiscal years is presented below:

Noninterest Income

Noninterest income was $12.8 million for the fourth quarter of fiscal year 2017, a decrease of $2.6 million, or 17.1%. Of this movement, $2.0 million is due to a decrease in product and service fees primarily driven by a $0.9 million decrease in service charges and other fees reflecting lower interchange income under the "Durbin Amendment," as expected. Management expects a further quarter-over-quarter reduction of approximately $1.5 million in interchange income for the quarter ending December 31, 2017. Other noninterest income and wealth management fees also declined by $0.7 million and $0.4 million, respectively. The remaining $0.6 million is attributable to the net effect of the change in fair value of 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.

Exhibit 99.1

Noninterest Expense

Total noninterest expense was $55.3 million for the fourth quarter of fiscal year 2017, an increase of $0.4 million, or 0.7%. The increase in noninterest expense was driven by a $1.4 million increase in other noninterest expense and a $0.4 million increase in net loss on repossessed property and other related expenses (i.e., "OREO"), partially offset by a decrease of $1.6 million in salaries and employee benefits. Included within the overall increase to noninterest expense was approximately $0.8 million of fixed asset write-offs and associated costs to upgrade our teller capture system, as disclosed last quarter which is not considered to be recurring, and a higher OREO charge this quarter.

The efficiency ratio¹ was 47.1% for the fourth quarter, a slight increase compared to 46.7%.

Provision for Income Taxes

The provision for income taxes for the fourth quarter of fiscal year 2017 was $16.7 million, reflecting an effective tax rate of 30.8% of income before income taxes, compared to an effective tax rate of 34.5%. The lower effective tax rate for the quarter was driven, in part, by tax benefits related to the vesting of shares of company stock. Approximately $1.4 million of this benefit related to shares granted to certain employees concurrent with the company's Initial Public Offering that vested during the quarter and were one-time in nature.

Capital

Tier 1 and total capital ratios were 11.4% and 12.5%, respectively, as of September 30, 2017, compared to 11.5% and 12.6%, respectively. The common equity tier 1 capital ratio was 10.7% as of September 30, 2017, compared to 10.7%. The tier 1 leverage ratio was 10.3% as of September 30, 2017, compared to 10.3%. All regulatory capital ratios remain above regulatory minimums to be considered "well capitalized."

During the quarter $5.6 million was deployed to repurchase and retire approximately 200 thousand shares of the Company's common stock under the repurchase program authorized by the Board of Directors at an average price of $34.46.

On October 26, 2017, the Company’s Board of Directors declared a dividend of $0.20 per common share payable on November 22, 2017 to stockholders of record as of close of business on November 10, 2017. The aggregate dividend payment will be approximately $11.8 million.

Fiscal Year 2017 Highlights (all comparisons refer to the fiscal year 2016, except as noted)


•	Net interest income for fiscal year 2017 was $404.9 million, an increase of $35.2 million, or 9.5%. The increase was primarily attributable to higher loan interest income driven by 10.8% growth in average loans outstanding between the periods combined with a 5 basis point increase in the yield on total loans, partially offset by an 8 basis point increase in the cost of deposits.


•	Customer loan balances increased by $350.2 million, or 4.1%, during fiscal year 2017. The net fiscal year-to-date growth was primarily driven by $370.7 million of CRE loan growth and more modest C&I growth, partially offset by reductions in residential real estate and agriculture loans.


•	Average total deposit growth was $897.0 million, or 11.3% for fiscal year 2017. Average noninterest-bearing deposits were $1.81 billion while interest-bearing deposits averaged $7.01 billion for the same period. Total deposit balances for fiscal year 2017 increased by $372.8 million, or 4.3%.

•

Provision for loan and lease losses was $21.5 million for fiscal year 2017, an increase of $4.6 million, or 27.0%. Net charge-offs for fiscal year 2017 were $22.7 million, or 26 basis points of average total loans, an increase of $13.2 million, or 14 basis points of average total loans, driving the majority of the increase in provision for loan and lease losses. Net charge-offs were primarily concentrated in the C&I and agriculture loan portfolios.


•	Asset quality metrics remained stable as loans graded "Watch" decreased $16.0 million, or 4.9% to $311.6 million while loans graded "Substandard" decreased $8.8 million, or 3.6% to $232.8 million and total nonaccrual loans increased by $11.9 million, or 9.4% to $138.3 million at September 30, 2017.

Exhibit 99.1

•

Noninterest income for fiscal year 2017 was $56.1 million, an increase of $13.5 million, or 31.8%. Of this movement, $7.0 million is attributable to the net effect of the change in fair value of 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. The remaining $6.5 million increase in noninterest income was primarily due to a $2.4 million increase in service charges and other fees, a $1.8 million increase in wealth management fees and a $1.7 million increase in other income.


•	Noninterest expense for fiscal year 2017 was $216.6 million, an increase of $9.0 million, or 4.3%. The increase was due to a $19.1 million increase in salaries and employee benefits, a $2.8 million increase in data processing, a $1.5 million increase in professional fees, partially offset by a $15.0 million decrease in acquisition expenses.


•	The efficiency ratio¹ was 46.5% for fiscal year 2017, compared to 49.6%, with a large portion of the decrease driven by the absence of one-time acquisition costs in fiscal year 2017.


•	The effective tax rate for fiscal years 2017 and 2016 was 32.4% and 32.7%, respectively.

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. We disclose net interest income and related ratios and analysis on a taxable-equivalent basis, which may also be considered non-GAAP financial measures. We believe this presentation to be the preferred industry measurement of net interest income as it provides a relevant comparison of net interest income arising from taxable and tax-exempt sources. In addition, certain performance measures, including the efficiency ratio and net interest margin utilize net interest income on a taxable-equivalent basis.

In particular, we evaluate our profitability and performance based on our adjusted net income, adjusted earnings per common share, tangible net income and return on average tangible common equity. Our adjusted net income and adjusted earnings per common share exclude the after-tax effect of items with a significant impact to net income that we do not believe to be recurring in nature, (e.g., one-time acquisition expenses). Our tangible net income and return on average tangible common equity exclude the effects of amortization expense relating to intangible assets and related tax effects from the acquisition of us by National Australia Bank Limited ("NAB") 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 excluding significant nonrecurring items (for adjusted net income and adjusted earnings per share) and based on our cash payments and receipts during the applicable period (for tangible net income and return on average tangible common equity).

Exhibit 99.1

We also evaluate our profitability and performance based on our adjusted net interest income, adjusted net interest margin, adjusted interest income on non ASC 310-30 loans and adjusted yield on non ASC 310-30 loans. 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 and the ratio of our tangible common equity to common shares outstanding. 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. We also believe the ratio of our tangible common equity to common shares outstanding is helpful in understanding our stockholders’ relative ownership position as we undertake various actions to issue and retire common shares outstanding.

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.
