What the filing says
Prosperity Bancshares completed three mergers in 2026: American Bank Holding (Jan 1, $1.9B assets), Southwest Bancshares/Texas Partners (Feb 1, $1.9B), and Stellar Bancorp (Jul 1, $10.4B). Total assets grew 41.1% to $54.1B; loans grew 45.5% to $32.1B; deposits grew 48.4% to $41.2B. Q3 net income $141.5M ($1.18 EPS); excluding $69.7M merger expenses, adjusted earnings $200.8M ($1.67 EPS). Board approved 6.67% dividend increase to $0.64/share (23rd consecutive annual increase, 10.4% CAGR). Repurchased 1.5M shares YTD at avg $68.63/share for $102.6M.
Why this rating
Transformational organic growth through acquisitions expanding asset base 41% in one year, materially strengthening competitive scale. Profitable integration execution demonstrated with strong Q3 results and improved net interest margin (3.73% vs 3.24% prior year). Relative to $6.4B market cap, ~$15.8B in acquired assets is substantial. Dividend growth streak reinforces confidence. Dilution from share issuance (27M shares issued) partially offsets EPS accretion.
