The company's third-quarter pre-provision net revenue -- aside from bargain purchase gains on acquisitions and gains on available-for-sale securities -- grew by 23% from a year earlier to $63.9 million, reflecting a 12% increase in net interest income to $132.6 million, from strong loan growth, while the net interest margin bucked the industry trend and expanded to 3.55% from 3.38% in the third quarter of 2011. Excluding bargain purchase gains booked after failed-bank acquisitions in both periods and gains on securities available for sale, Wintrust's noninterest income grew 41% year-over-year, to $55.9 million in the third quarter.

Noninterest expense was up 17% year-over-year, to $124.6 million. Third-quarter earnings were $32.3 million, or 66 cents a share, increasing from $30.2 million, or 65 cents a share, in the third quarter of 2011. The company's second-quarter ROA was 0.77% and its return on average common equity was 7.57%. Jefferies analyst Emlen Harmon reiterated his "Hold" rating for Wintrust on Oct. 18, after the company reported its third-quarter results, saying "concerns about the longer-term earnings run-rate surfaced as a portion of outsized expense growth will be run-rated. We remain cautious on the shares, as the roll-off of mortgage revenue and modest margin compression weigh on the company's ability to generate significant earnings growth post-4Q. Harmon has a $35 price target for Wintrust's shares, and estimates the company will earn $2.50 a share in 2013. WTFC data by YCharts Interested in more on Wintrust?
