Great Southern Bancorp (GSBC) Q4 2025 earnings review
Earnings Hold Up, But The 'Swap Cliff' and Loan Runoff Are Here
Great Southern Bancorp delivered a respectable Q4 EPS of $1.45 (+14% YoY), primarily driven by lower non-interest expenses and stable margins. However, the growth narrative is cracking. The long-awaited 'Swap Cliff' has arrived—interest income from a terminated swap fell from ~$2.0M/quarter to just $134k, causing Net Interest Income (NII) to contract sequentially. More concerning is the balance sheet shrinkage: Total Loans fell 7.1% YoY ($333M) as payoffs accelerated and originations slowed. While credit quality remains pristine (zero provision expense), the core revenue engine is stalling due to volume declines and the loss of the swap subsidy.
🐂 Bull Case
Credit metrics remain excellent. Non-performing assets (NPAs) dropped to 0.15% of total assets (from 0.16% YoY). The company recorded $0 provision for loan losses in Q4 and the full year, a significant earnings tailwind compared to peers building reserves.
Management reduced non-interest expense by roughly $1M YoY (-2.6%) to $36.0M. In an inflationary environment, GSBC's ability to lower operating costs (efficiency ratio 63.9%) protects the bottom line despite revenue headwinds.
🐻 Bear Case
The termination of the interest rate swap income is a permanent hit. NII fell $1.6M sequentially (Q3 to Q4). With this $2M/quarter subsidy now effectively gone (only $0.13M in Q4 vs $2.0M normally), 2026 begins with a revenue hole.
Loans contracted by $333M (-7.1%) YoY. Multi-family loans alone fell $161M. A shrinking asset base makes growing Net Interest Income mathematically difficult, regardless of margin performance.
⚖️ Verdict: ⚪
Neutral. The bank is managed safely with excellent credit and cost control, which supports the valuation. However, the combination of a shrinking loan book and the structural loss of ~$8M annual swap income creates a difficult path for earnings growth in FY26.
Key Themes
The 'Swap Cliff' Materializes
For years, GSBC benefited from accreting income from a swap terminated in 2020. That ended in October 2025. In Q4, swap income collapsed to $134k from $2.0M in Q3. This single factor drove NII down 3.2% sequentially despite stable deposit costs. This is a permanent reset of the revenue baseline.
Accelerating Loan Runoff
Reversing. The loan portfolio is not just stagnant; it is shrinking rapidly. Net loans fell $111M in Q3 and another $333M in Q4 YoY. The declines are broad-based: Multi-family (-$162M), Construction (-$97M), and Residential (-$51M). Payoffs are exceeding originations, indicating either pricing discipline or a lack of competitive demand.
NIM Expansion (Peaking?)
Stable/Decelerating. Net Interest Margin (NIM) improved significantly YoY (3.70% vs 3.49%) due to lower funding costs and asset repricing. However, NIM contracted sequentially (3.72% in Q3 to 3.70% in Q4) specifically due to the loss of swap income. Without the swap, organic NIM pressure may return unless funding costs drop aggressively.
Deposit Cost Rationalization
Management is effectively lowering funding costs. The average rate on interest-bearing liabilities dropped to 2.37% (vs 2.96% YoY). Time deposit costs fell 50 bps and brokered deposits fell 76 bps YoY. As high-cost CDs mature, GSBC is successfully repricing them lower (market replacement rates ~2.70-3.10% vs maturing rates up to 3.53%).
One-Time Items Skew Expenses
Non-interest expense looks cleaner YoY ($36.0M vs $36.9M), but the comparison is aided by a $2.0M litigation expense in 24Q4. 25Q4 had its own noise: $0.5M in branch closure/facility costs. Underlying 'run-rate' expenses are stable, but not declining as aggressively as the headline suggests.
Capital Return Strategy
GSBC remains shareholder-friendly. In Q4, they repurchased 241,301 shares ($59.33 avg) and paid $0.43 dividend. Total equity reduction from returns was $19.2M in the quarter. Tangible Common Equity ratio remains robust at 11.2%, providing ample dry powder for continued buybacks given the lack of loan growth.
Other KPIs
Reversing. Down $0.4M YoY and down $1.6M sequentially. The sequential drop is entirely attributable to the $1.9M reduction in swap income. This sets a lower baseline for 2026.
Stable/Excellent. Decreased from $9.6M YoY. Net charge-offs were negligible (recoveries of $22k). The absence of credit stress is the company's strongest fundamental trait.
Decelerating. Down $123M YoY. Brokered deposits decreased $109M, signaling a deliberate choice to let higher-cost funding run off as loan demand waned.
Guidance
Stable. Consistent with FY25 actuals (18.7%). Driven by investment tax credits and tax-exempt loans.
Positive. Maturing deposits ($591M within 3 months) have a weighted average rate of 3.53%. Replacing these at ~2.90% (midpoint) offers ~60bps of cost relief on that tranche, creating a tailwind for NIM.
Key Questions
Loan Contraction Floor
Net loans have declined for consecutive quarters, down 7% YoY. With the 10-year yield and rates fluctuating, do you see a floor forming in Q1/Q2 2026, or should we model continued runoff in the Multi-family portfolio?
NII Baseline post-Swap
Q4 NII dropped $1.6M sequentially, largely due to the swap expiration. Is $49M the new quarterly run-rate baseline, or do expected deposit repricings in Q1 provide enough lift to grow NII back above $50M immediately?
Capital Deployment Priorities
With loans shrinking and capital ratios building (TCE 11.2%), will you accelerate buybacks beyond the current pace, or are you preserving capital for potential M&A or organic growth opportunities later in 2026?
Expense Outlook
Q4 expenses included ~$0.5M in facility adjustments. Excluding that, the run rate is ~$35.5M. Is this a sustainable level for 2026, or should we expect inflation/tech investments to push this back toward the $37M range?
