# Wintrust files Q3 2026 earnings release Oct 19; exhibit body missing so figures are unavailable

## Summary
- Wintrust Financial Corporation announced third-quarter 2026 earnings on October 19, 2026, in an 8-K signed by EVP and CFO David L. Stoehr.
- The filing points to a Q3 2026 earnings press release (Exhibit 99.1) and an earnings presentation (Exhibit 99.2) posted on the company's website.
- Only the presentation's title page and a 'Q3 2026' label appear in the appended text; no EPS, revenue, net interest margin, credit, or guidance numbers are recoverable.
- Non-GAAP supplemental reconciliations are cited at pages 33-35 of the press release and pages 29-32 of the presentation, implying adjusted metrics were reported but their values are absent here.
- Confidence is low: an investor must open the full press release to get actual quarterly results.
