What stood out

The parts that mattered.

Pulled out of the filing itself, with the figures the company reported.

Net income and EPS improved year-over-year
Net income rose to $27.0 million and diluted EPS to $0.53 for the three months ended March 31, 2026, from $24.7 million and $0.46 for the three months ended March 31, 2025.
Net interest income growth
Net interest income increased $6.7 million (6.7%) to $105.9 million for Q1 2026 from $99.3 million in Q1 2025.
Lower interest expense supported margins
Interest expense declined $3.9 million (9.1%) to $39.2 million for the three months ended March 31, 2026 from $43.1 million in the prior-year period, helping tax-equivalent NIM rise to 4.24% (from 4.20%).
Balance-sheet growth in interest-earning assets
Average interest-earning assets increased $547.0 million (5.7%) to $10,139,233 (dollars in thousands) for the three months ended March 31, 2026 compared with $9,592,205 for the same period in 2025.
Share repurchase activity
The company repurchased 134,362 shares during Q1 2026 at a weighted-average price of $31.06 per share; as of March 31, 2026 the number of shares that may still be repurchased was 1,191,820 (based on the closing price).
What to watch

And the other side of it.

The offsets in the same document — the things a summary that only listed the good news would have left out.

Rising noninterest expense
Noninterest expense increased $5.0 million in Q1 2026 versus Q1 2025, contributing to a wider efficiency ratio of 63.27% (up from 61.93%).
Loan-yield compression
Average yield on loans decreased to 6.51% for Q1 2026 from 6.66% for Q1 2025, and overall average yield on interest-earning assets fell to 5.80% from 6.02%.
Allowance sensitivity
As of March 31, 2026, a 5% increase in historical loss rates would raise funded reserves by $1.1 million; a 5% increase in qualitative risk factors would add $2.9 million; combined quantitative and qualitative increases would impact reserves by $3.6 million.
Merger completion is not guaranteed
Completion of the proposed merger with Prosperity remains subject to Stellar shareholder approval at a special meeting scheduled for May 27, 2026, and the Merger is expected to be completed on or about July 1, 2026 (subject to customary closing conditions).
No material update to risk factors
The company states there have been no material changes in the risk factors previously disclosed in the 2025 Form 10-K.
