Prosperity Bancshares Reports Q3 2026 Growth Driven by Recent Mergers
Prosperity Bancshares (PB) reported strong third-quarter 2026 results, significantly bolstered by the integration of American Bank, Southwest, and Stellar acquisitions. Total assets surged to $54.1 billion, a 41.1% increase year-over-year, while total deposits rose 48.4% to $41.2 billion. The company's tax-equivalent net interest margin also saw a notable expansion, rising 49 basis points to 3.73% compared to the previous year. Despite one-time merger-related expenses of nearly $70 million, the bank demonstrated operational strength with an adjusted efficiency ratio of 48.0%. Management expects to realize $65 million to $70 million in additional pretax savings once system conversions are complete. Looking ahead to 2027, the company anticipates a net interest margin between 3.80% and 3.85%, though loan growth is expected to remain flat as historical runoff from acquired institutions offsets new production.
