Record Earnings on Balance Sheet Growth

Wintrust Financial Corporation (NASDAQ:WTFC) reported third quarter 2026 results on October 19, with record net income of $239.1 million, or $3.37 per diluted share, compared with $3.30 in the second quarter and a $3.29 consensus. It was the seventh consecutive record quarter. Revenue of $757.9 million was 8.7% higher than a year earlier, and nine-month net income reached $700.1 million, up 17%.

The Illinois-based group operates community banks across the greater Chicago, southern Wisconsin, west Michigan, northwest Indiana and southwest Florida areas, alongside specialty finance and wealth management businesses, with about $74.7 billion in assets. Pre-tax, pre-provision income was $352.2 million, up from $341.1 million, and management said it is well positioned to deliver further revenue growth as it closes out the year.

Margin, Fees and Credit

Net interest income rose 16% annualized to $621.6 million from $597.4 million, as average earning assets grew $2.1 billion. The net interest margin was 3.49%, down one basis point, which management described as in line with guidance. Loans grew $1.1 billion and deposits $1.3 billion, so the loan-to-deposit ratio stayed at 91.0%, and non-interest-bearing deposits were 19% of the total. Growth was diversified across portfolios, which reduces reliance on any one lending segment.

Fee income was softer. Non-interest income fell to $136.3 million from $141.3 million, with mortgage banking down to $25.5 million and a $1.6 million net loss on securities against a $1.8 million gain, while wealth management rose by $1.1 million. Expenses rose $8.1 million to $405.7 million. Net charge-offs increased to $21.0 million, or 15 basis points of loans, and the provision was $25.9 million, up from $23.1 million in the second quarter, although non-performing loans were stable at 0.31% of loans. Management guides to mid-single-digit expense growth.

Capital, Credit and Rate Risks

Management expects further revenue growth and positive operating leverage this year, and it points to deposit share gains in Illinois and expansion in Wisconsin and west Michigan. The efficiency ratio of 53.41% suggests costs are well controlled, and the allowance rose to $486.1 million from $481.2 million, which provides a buffer if credit conditions soften.

Risks center on credit, capital and rates. Net charge-offs are rising from low levels, and the allowance reflects uncertainty about credit spreads, equity valuations and the job market. Tangible book value per share fell to $88.18 from $92.13 as accumulated other comprehensive losses roughly doubled to $863.8 million, while the CET1 ratio of 10.5% leaves moderate room for faster growth. Lower mortgage activity could also weigh on fees.

Consistency With Rising Credit Costs

Wintrust's record run shows a balance sheet that can grow at a steady pace while keeping the margin close to guidance, and its cost base remains efficient. The quarter also carried a few softer signals, namely lower fees, higher charge-offs and a lower tangible book value. Further records could depend on how credit costs develop, whether deposit growth keeps funding loans, and whether rate moves stay manageable for the securities portfolio. The 53.41% efficiency ratio gives management room to absorb higher credit costs if conditions soften.
