A cleaned-up bank still needs deposits

01 Running thesis

Margin repair, deposit test

The main story at Simmons First is the 2025 balance sheet reset. The bank moved about $3.59 billion of held-to-maturity securities into available-for-sale, then sold about $3.16 billion of low-yield bonds. It used the cash mainly to pay down expensive wholesale funding and public funds. That sale created a realized after-tax loss of $625.6 million, but it also removed assets that were hurting future earnings.

The payoff is showing in net interest margin, which means the spread between what the bank earns on loans and securities and what it pays for deposits and borrowings. Fully taxable equivalent net interest margin was 3.84% in Q1 2026, up from 3.81% in Q4 2025 and 2.95% in Q1 2025. Management also said on the Q4 2025 call that linked-quarter margin rose 31 basis points, with the restructuring a major driver.

The bull case is that SFNC now earns a better spread, has a cleaner securities book, and has room for more loan income as older sub-4% loans reprice over the next 24 months. The Q2 2026 call also pointed to loan growth near the high end of management's low to mid-single-digit outlook and 4% annualized growth in non-interest-bearing deposits.

The bear case is that this is still a slow-growth regional bank in a hard deposit market. Management called deposit competition very fierce. If Simmons cannot add enough low-cost checking and operating accounts, it may have to lean more on brokered deposits, public funds, or FHLB advances, which can eat into the margin gain.

Jul 2026The Q2 2026 call kept the post-restructuring thesis intact. Management pointed to benefits from the asset-sensitive shift, but also said deposit competition remains very fierce.
May 2026The Q1 2026 filing showed fully taxable equivalent net interest margin at 3.84%. It also showed loans of $17.93 billion and deposits of $20.20 billion at March 31, 2026.
Jan 2026The Q4 2025 call showed the restructuring flowing into earnings power. Management said linked-quarter margin improved 31 basis points, helped by the balance sheet reset and core margin expansion.
Nov 2025The Q3 2025 filing confirmed the bank sold low-yield securities and used the proceeds to reduce high-cost wholesale funding. The action created a large loss, but improved future earnings potential.
Aug 2025The company disclosed the key restructuring steps, including the reclassification of about $3.6 billion of HTM securities and the sale of about $3.2 billion of AFS securities.
02 Business model

Borrow cheap, lend carefully

Simmons First makes most of its money the normal bank way. It gathers deposits from people, businesses, and public customers, then uses that funding to make loans and hold securities. Net interest income is the difference between the yield on those assets and the cost of deposits and borrowings.

Fee income adds a second stream, but it is smaller. In Q1 2026, noninterest income was $44.2 million. The recurring fee base included service charges on deposit accounts, wealth management fees, debit and credit card fees, and other customer fees.

The model breaks when credit losses rise, deposit costs jump, or loan prices get too low. SFNC is trying to avoid that by keeping underwriting tight and by refusing to chase loans at what management called irrational competitor pricing. That protects credit quality, but it can also slow growth.

03 Product portfolio

What Simmons sells

Cash cow

Core deposits

Checking, savings, and transaction accounts fund the loan book. Core deposits were 83.5% of total deposits at March 31, 2026, so keeping this base matters more than chasing hot money.

Steady

Commercial real estate and construction loans

Real estate is the largest loan bucket. It can produce solid yields, but it also creates concentration risk if property values or rents weaken.

Growth engine

Commercial and agricultural loans

These loans serve operating businesses and farms across the Mid-South footprint. Commercial loans rose 6.2% from December 31, 2025 to March 31, 2026.

Steady

Residential and consumer loans

This includes single-family residential, credit card, and other personal loans. Consumer loans were only 1.5% of total loans at March 31, 2026.

Option

Mortgage warehouse and municipal loans

These sit in the other loan category. Other loans rose in Q1 2026 as mortgage warehouse demand improved.

Steady

Wealth, card, and service fees

These services bring in fee income that does not depend directly on loan balances. Wealth management fees were $10.5 million in Q1 2026.

05 Risk factors

What could break the thesis

Core deposit shortfall

High impact · Medium odds

The restructuring reduced the need for expensive wholesale funding, but it did not remove the need to fund loan growth. Deposits were $20.20 billion at March 31, 2026, and brokered deposits were $1.91 billion. If checking and other core balances stall, SFNC may pay more for funding than the bull case assumes.

We watchCore deposits as a share of total deposits, non-interest-bearing deposit growth, and brokered deposits.

Rate cuts hurt an asset-sensitive bank

Medium impact · Medium odds

SFNC shifted toward an asset-sensitive balance sheet, which means earnings tend to do better when asset yields hold up or rise. The Q1 2026 filing said a 100 basis point rate drop would reduce net interest income by 2.08% versus the base case over the next 12 months. A 200 basis point drop would reduce it by 3.70%.

We watchFed rate path, SFNC net interest margin, and the company’s interest rate sensitivity table.

Real estate credit flare-up

High impact · Medium odds

Real estate loans were 77.8% of total loans at March 31, 2026. Nonperforming assets rose to 0.63% of total assets in Q1 2026, partly because of one $26.9 million real estate construction relationship. Management said that loan was well collateralized, but more cases like it would change the credit story.

We watchNonperforming assets, criticized loans, construction and development loans, and net charge-offs.

Loan pricing turns irrational

Medium impact · Medium odds

Management has said some competitors are pricing commercial loans too aggressively. If SFNC matches those prices, loan yields could fall. If it refuses, loan growth could slow even with a healthy pipeline.

We watchLoan yield, new loan production, commercial pipeline, and management comments on pricing discipline.

One-time reset does not become lasting growth

Medium impact · Medium odds

The 2025 securities sale made the bank more profitable on a run-rate basis, but it was not free. The realized after-tax loss was $625.6 million. Investors still need proof that higher margin can turn into steady earnings growth, not just a rebound from a balance sheet fix.

We watchNet interest income growth, adjusted earnings per share, tangible book value per share, and expense control.
06 Quick answers

In one breath

What does Simmons First National do?

Simmons First is the holding company for Simmons Bank. It runs a regional banking business across Arkansas, Kansas, Missouri, Oklahoma, Tennessee, and Texas.

Why did SFNC sell securities in 2025?

The bank sold about $3.16 billion of low-yield securities after moving a larger block into available-for-sale. It used the proceeds mainly to pay down higher-cost funding, which improved the bank’s future net interest margin.

What is the biggest risk for SFNC stock?

The biggest watch item is funding. If Simmons cannot grow low-cost core deposits, higher funding costs could offset the margin gains from the restructuring.

Is SFNC mainly a real estate lender?

Yes, by loan mix. Real estate loans were 77.8% of total loans at March 31, 2026, so property credit quality is a key part of the story.
