Prosperity Bancshares aims for a 3.70%-3.75% net interest margin exit in 2026 following its Stellar Bancorp merger completion.
Prosperity Bancshares has targeted a net interest margin (NIM) exit range of 3.70% to 3.75% for 2026 after completing its merger with Stellar Bancorp on July 1, 2026. The combined entity now includes Stellar Bank, which operated 52 banking offices prior to the merger.
The merger positions Prosperity Bancshares to expand its footprint and improve financial metrics, though prior NIM performance or consensus expectations were not disclosed. The company’s leadership highlighted the strategic benefits of the integration during its Q2 2026 earnings call.
No immediate market reaction was reported following the announcement, which focused on long-term financial goals rather than short-term adjustments.
