Cullen/Frost Bankers is the parent company of Frost Bank, one of the largest Texas-based banks with a 158-year history, and the question for the next twelve months is whether the company can convert the Texas commercial banking growth, the energy and consumer real estate loan growth, the deposit franchise quality, and the long-standing culture of credit discipline into the kind of positive operating leverage the company has been telegraphing. The Q2 2026 print was the cleanest test yet of that thesis, and the cleanest signal is that on July 30, 2026, Chairman and Chief Executive Officer Phillip D. Green and Chief Financial Officer Daniel Geddes reported the Q2 2026 net income of $172.1 million up 9.6 percent year over year and the Q2 2026 diluted EPS of $2.70 up 13.0 percent year over year. The combination of the Q2 2026 net income of $172.1 million, the Q2 2025 net income of $157.0 million, the Q2 2026 net income available to common shareholders of $170.4 million, the Q2 2025 net income available to common shareholders of $155.3 million, the Q2 2026 basic EPS of $2.70, the Q2 2025 basic EPS of $2.39, the Q2 2026 diluted EPS of $2.70, the Q2 2025 diluted EPS of $2.39, the H1 2026 net income of $343.0 million, the H1 2025 net income of $307.9 million, the H1 2026 basic EPS of $5.35, the H1 2025 basic EPS of $4.69, the H1 2026 diluted EPS of $5.35, the H1 2025 diluted EPS of $4.69, the Texas commercial banking growth, the 158-year history, the 32.9 percent non-interest-bearing savings and interest checking mix, the 23.3 percent MMA mix, the 28.5 percent time accounts mix, the 0.05 percent Q2 2026 non-interest-bearing savings blended cost, the 0.29 percent Q2 2026 interest checking blended cost, the 1.23 percent Q2 2026 MMA blended cost, the 1.72 percent Q2 2026 time accounts blended cost, the 2.18 percent Q2 2026 total cost, the 0.32 percent Q2 2026 non-interest-bearing deposit growth, the 15.3 percent energy loan CAGR since 2014, the 41.0 percent energy loan CAGR since 2015, the 27.6 percent energy loan CAGR since 2016, the 28.2 percent energy loan CAGR since 2017, the 3.2 percent energy loan CAGR since 2018, the 1 percent energy loan growth since Q1 2015, the 19.7 percent energy loans as percent of total loans in Q2 2026 up from 11.6 percent at the end of 2019, the 26.6 percent consumer real estate loans CAGR from June 2020 to June 2026, the 23.0 percent fee income as percent of non-TE total revenue in 1H 2026, the 49.8 percent investments and insurance as percent of total non-interest income in 1H 2026, the 53.0 percent Q2 2026 loans to deposits ratio, the Q2 2026 average spread to Ameribor of 2.46 percent, the Q2 2026 average spread to SOFR of 2.40 percent, the Q2 2026 average spread to Prime of 0.65 percent, the Frost long-standing culture of credit discipline, the top quality customer service results in low customer attrition, the goal to drive consistent balanced growth in deposits and loans, the regional banks deposit portfolio comparison, the diversification of energy and non-energy loans, the loan composition in Q2 2026, the peak Y/Y growth in energy loans, the consumer real estate loan growth, the investments and insurance income contribution, the fee income stability, the non-accruals and ACL trends, and the Texas super-regional bank positioning is the cleanest single read on what the Texas-growth pivot is producing. The strategic tension is the Texas commercial banking growth against the broader U.S. interest rate and credit cycle, and the forward question is whether the company can convert the Texas commercial banking growth, the energy and consumer real estate loan growth, the deposit franchise quality, and the long-standing culture of credit discipline into the positive operating leverage the company has been telegraphing.
