Prosperity Bancshares Stock Earnings Reports

Prosperity Bancshares reported Q1 2026 results impacted by multiple mergers and a core systems conversion. The company completed mergers with American Bank Holding (closed Jan 1) and Southwest Bancshares (closed Feb 1), and received regulatory approvals to close the Stellar Bancorp acquisition (expected July 1, 2026). Q1 GAAP net income was $116 million ($1.16 diluted EPS), or $149.9 million ($1.50 diluted EPS) excluding $42.5 million of merger-related charges — a 9.5% increase in adjusted EPS versus prior year. Loans and deposits grew materially on an acquired basis (loans $25.2B, +15.1% YoY; deposits $32.6B, +16.4% YoY); core organic loans were slightly down outside acquisition impacts. Net interest margin expanded to 3.51% (tax-equivalent), helped by asset repricing and acquired portfolios; management models a 2026 average NIM of ~3.60% with an exit near ~3.70%. Noninterest expense rose due to merger costs (efficiency ratio 59.2% GAAP; 47.6% excluding merger charges). Asset quality showed nonperforming assets of $122M (33–48 bps measures) and an allowance for credit losses of $421M; Q1 net charge-offs were $41M (largest in company history), driven by two specific credits, one a ~$30M loss tied to a Medicare-insurance receivable issue. Management reiterated focus on integrating the three acquisitions, achieving announced cost saves (some in 2026, more in 2027), disciplined underwriting amid competitive markets, continued opportunistic buybacks (837k shares repurchased in Q1 for $57M), and maintaining conservative loan-to-deposit discipline (policy review at ~85%).
