Great Southern Bancorp (GSBC) Q3 2026 earnings review
Great Southern loan pipeline grows, but bond losses cut capital
Great Southern Bancorp, a Missouri-based commercial and retail bank, kept its lending spread steady while its loan book shrank again. Profit per share excluding a one-time swap accounting charge fell 4% from a year ago to $1.50, while net loans dropped by $59 million as apartment and commercial real estate borrowers paid off debt. Chief executive Joseph W. Turner bought $400 million of fixed-rate mortgage bonds funded with overnight loans, a move that cut the bank's tangible equity ratio to 10.4% as bond yields climbed.
| Net interest income, excluding swap adjustments | +1.6% from a year ago, by our math |
|---|---|
| Profit per share, excluding one-offs | $1.50 -4% from a year ago |
| Period-end net loans | $4.25B -$59M from last quarter |
| Retail CD replacement rate outlook | Raised middle of the range: 3.30% vs 2.95% prior |
⚖️ Verdict: 🔴 Bearish
The story got worse because management used short-term debt to buy fixed-rate bonds right as the Federal Reserve started raising interest rates again. That trade squeezes future lending margins, doubles paper bond losses and doubles overnight borrowings at the same time customer deposits are leaving. The good news: unfunded construction loan commitments jumped by $123 million, and the nine branch closures finished on October 1.
The question now is whether the rising construction pipeline can finally stop the loan book from shrinking while overnight borrowing costs climb. Either those new commitments turn into funded loans and lift interest income, or borrower payoffs and pricier short-term debt compress the bank's profit spread. Fourth-quarter loan balances and net interest margin will tell.
🐂 Bull Case
Unfunded Construction Deals Rebuilt the Pipeline
Great Southern tracks its lending pipeline through unfunded loan commitments, which are credit lines and construction loans approved for borrowers who have not yet drawn the cash. Chief executive Joseph W. Turner said this pipeline stayed strong during the quarter because builders took out new construction loans. Total unfunded commitments rose by $123.2 million from June to $1.20 billion, up 12.9% from a year ago.
Unfunded commercial construction lines grew $109.2 million from last quarter to $641.1 million, and unclosed commercial real estate commitments rose $19.0 million to $68.2 million. That jump prompted a $674,000 credit reserve charge for unfunded lines. This pipeline growth does not immediately stop the loan book from shrinking, because construction borrowers must spend their own cash first before drawing bank funds over the next year.
What to watch: quarterly net change in funded construction loans over the next two quarters. A sustained rise would show these commitments are turning into interest-earning loans fast enough to offset commercial real estate payoffs.
Deposit Pricing Held Up the Margin
Net interest margin (NIM), the profit spread a bank earns between its loans and its deposits, reached 3.75% this quarter. That beat the 3.72% figure from a year ago and nearly matched last quarter's 3.76%. Great Southern held its margin steady even though a terminated interest rate contract that added $2.0 million to interest income in last year's third quarter expired in October 2025.
By our math, net interest income excluding swap adjustments grew 1.6% from a year ago. The bank protected its lending spread by cutting the average interest rate it pays on deposits by 0.55 percentage points from a year ago to 1.93%, outpacing the 0.25-point drop in loan yields. Starting in the fourth quarter, year-over-year comparisons will no longer face that $2.0 million quarterly hurdle.
What to watch: average rate paid on retail time deposits next quarter. A climb toward the new 3.10% to 3.50% replacement range would show that September's Federal Reserve rate hike is raising funding costs again.
Branch Closures Finished on Schedule
On October 1, the Missouri lender finished closing nine retail branches across Arkansas, Kansas, Iowa and Missouri and cut 66 staff positions. The bank moved $11.1 million of closed branch buildings into properties held for sale and expects the cuts to lower annual operating expenses by $4.4 million to $4.8 million starting in the fourth quarter.
Because management expects some customers at those nine branches to move their $195 million of deposits elsewhere, the bank plans for $2.3 million to $2.7 million in annual pre-tax profit gains. By our math, the gap between those two targets leaves $1.7 million to $2.5 million a year for lost account fees and pricier replacement borrowing.
What to watch: fourth-quarter total non-interest expense. A drop below $35.5 million would show the branch savings are reaching the bottom line rather than being eaten up by computer system upgrades.
🐻 Bear Case
A $400 Million Bond Trade Squeezes Margin and Capital
"Our third quarter results demonstrate the durability of our core banking franchise and the consistency of our operating model," chief executive Joseph W. Turner said. While excess capital had been building up on the balance sheet, the bank shifted course this quarter and bought $400 million of fixed-rate mortgage bonds "to help mitigate the risk of potential significant future market interest rate declines".
- Available-for-sale bond portfolio: up $349.4 million from June to $853.2 million
- Paper losses on bonds and swaps: nearly doubled from $37.7 million in June to $65.4 million after tax
- Tangible common equity ratio: fell 1.1 percentage points in one quarter to 10.4% of tangible assets
Because Great Southern funded these 5-year bonds (yielding 4.80% to 5.00%) with overnight Federal Home Loan Bank (FHLB) loans costing 4.26% at quarter-end, the thin spread is "expected to modestly reduce our overall net interest margin percentage in future periods". Meanwhile, the Federal Reserve raised rates by 0.25 percentage points in September, which cut the market value of fixed-rate bonds and shrank book value per share to $56.97.
What to watch: net interest margin and accumulated bond losses in the fourth quarter. A drop in NIM below 3.70% would show that funding 5-year bonds with overnight debt is squeezing lending profitability as short-term rates rise.
Customer Payoffs Keep Shrinking the Loan Book
Great Southern's funded loan portfolio shrank again as commercial real estate and apartment borrowers paid off or refinanced their loans elsewhere. Net loans fell $59.3 million during the third quarter to $4.25 billion, bringing the nine-month decline to $108.4 million (-2.5%). Gross loans are down 4.9% from a year ago.
- Multi-family apartment loans: down $105.6 million over the first nine months of 2026
- Commercial real estate loans: down $95.8 million over the same nine-month period
- Average total loans: $4.34 billion in the third quarter, down $261.4 million (-5.7%) from a year ago
Two large loan payoffs brought in $282,000 of one-time prepayment fees this quarter, up from $78,000 a year ago. However, a shrinking loan book leaves the bank with fewer high-yielding assets to earn interest in future quarters, forcing it to rely on lower-yielding mortgage bonds.
What to watch: period-end net loans in the fourth quarter. A further drop below $4.20 billion would show that customer refinancing continues to outrun new construction loan draws.
Overnight Debt Replaced Departing Deposits
While the bank has used wholesale funding adjustments to manage its interest expenses, its reliance on short-term debt jumped this quarter. Turner said Great Southern "intentionally allowed $300 million of higher-cost brokered deposits to run off during the nine-month period", including a $211.8 million drop in the third quarter alone, while total deposits fell $232.1 million from June to $4.07 billion.
To pay for that deposit runoff and the $400 million bond purchase, the bank leaned on FHLB advances, "prioritizing FHLB borrowings given the favorable pricing advantage and flexibility". Short-term borrowings more than doubled in three months from $445.6 million to $995.5 million. Because overnight debt reprices immediately when the Federal Reserve hikes rates, this shift exposes the bank to higher funding bills.
What to watch: short-term borrowings and retail checking balances in the fourth quarter. An increase in overnight debt above $1.0 billion as the nine closed branches consolidate would show customer deposit losses are forcing even heavier wholesale borrowing.
Foreclosed Properties Absorb More Cash
Great Southern holds two main foreclosed commercial properties: an office building in Clayton, Missouri valued at $7.0 million and an eastern Iowa apartment complex valued at $2.3 million. Turner said independent appraisals back those figures and the bank "do not anticipate losses upon their ultimate resolution".
During the third quarter, the bank spent another $479,000 upgrading the Clayton office and $490,000 repairing the Iowa apartments, lifting foreclosed real estate (excluding closed bank branches) by $963,000 to $9.3 million. Separately, the earnings release does not include the watch-list table needed to check the $31.5 million Denver apartment loan flagged last quarter.
What to watch: the watch-list and special-mention loan table in the upcoming third-quarter 10-Q filing. Any downgrade of the $31.5 million Denver apartment loan would challenge the view that property issues are isolated.
👓 Other Themes
Swap Accounting Error Cut Reported Profit
Great Southern found that in past periods it did not hold enough qualifying variable-rate loans to back its $400 million of interest rate swaps under hedge accounting rules. Correcting this error required a one-time, non-cash pre-tax charge of $3.3 million ($2.5 million after tax, or $0.23 per share) that cut non-interest income by $4.1 million. The bank redesignated the swaps under new accounting rules and will recover the entire charge through interest income by May 2028.
💲 Other KPIs
Operating expenses rose 0.4% from a year ago and fell 5.1% from the second quarter, which had included $2.1 million of one-time branch closure charges. Salaries and benefits fell $565,000 (-2.8%) from a year ago on lower bonus accruals and early staff cuts, while computer license and support costs rose $434,000.
Period-end share count fell 4.6% from a year ago and 1.2% from June. Great Southern bought back 159,212 shares at an average price of $79.20 during the third quarter, while employees exercised options for 26,470 shares at $55.60. In October, the board approved a new one-million-share buyback plan.
Loans not paying as agreed rose $159,000 from June but remained at 0.03% of total loans, down from 0.04% a year ago. Net loan charge-offs were $397,000 (0.04% of average loans annualized), mostly from one $313,000 commercial business write-off, and the bank recorded zero provision for loan losses.
🔮 Guidance
Unchanged. The bank still plans for a combined federal and state tax rate of 18.0% to 19.5% in future quarters. Actual tax rates have landed below that range in three of the last four quarters — 16.4% in Q4, 15.3% in Q2 and 16.3% in Q3 — because employee stock option exercises created extra tax deductions.
Raised. Great Southern lifted its expected interest rate for renewing retail certificates of deposit by 0.35 percentage points at the middle of the range, to 3.30%. The increase follows the Federal Reserve's 0.25-point rate hike in September. Over the next three months, $362.5 million of time deposits carrying an average rate of 3.19% will mature.
Unchanged. Management kept its target for annual pre-tax profit gains from closing nine branches and cutting 66 roles, starting in the fourth quarter of 2026. The plan pairs $4.4 million to $4.8 million of annual cost savings with an implied $1.7 million to $2.5 million offset from lost deposits and fees by our math.
Unchanged. The bank reiterated its forecast for annual salary and building cost savings after completing the nine branch closures on October 1. That equates to $1.1 million to $1.2 million per quarter beginning in the fourth quarter.
New. Following the third-quarter hedge accounting correction, Great Southern expects to add about $520,000 per quarter to interest income from the fourth quarter of 2026 through the first quarter of 2028, plus $170,000 in the second quarter of 2028, recovering the $3.5 million gross charge.
Unchanged. The bank still expects fire sprinklers and building upgrades at its foreclosed Clayton office property to cost about $3.0 million in total during 2026. Having capitalized $582,000 in the first half and $479,000 in the third quarter, the outlook leaves about $1.9 million of spending for the fourth quarter by our math.
Unchanged. Total planned repairs on the foreclosed apartment building in eastern Iowa remain at about $800,000 over several months. The bank capitalized $490,000 of that budget in the third quarter, leaving about $310,000 to spend by our math.
❓ Key Questions
Why buy $400 million of fixed-rate bonds as rates rise?
Great Southern bought 5-year mortgage bonds yielding 4.80% to 5.00% funded by 4.26% overnight debt to guard against falling rates, right as the Federal Reserve hiked rates in September and signaled more increases could follow.
Did the $31.5 million Denver apartment loan deteriorate?
Last quarter's filing showed a $31.5 million Denver multi-family loan on the special-mention watch list after Great Southern bought back the shared portion. The earnings release omits the watch-list table.
How many deposits left the nine closed branches?
The nine branches consolidated on October 1 held $195 million in customer deposits at mid-year. Management has not disclosed how much of that money walked away during the third-quarter transition.
When will the $641 million construction pipeline fund?
Unfunded commercial construction commitments rose $109 million this quarter, but funded loans still fell $59 million because borrowers must spend their own equity before drawing bank credit.
