UPDATE 1-Wintrust Q2 profit trails market estimates

* Q2 EPS $0.25 vs est. $0.38 * Net interest income rise 44 pct

July 28 (Reuters) - Wintrust Financial Corp (WTFC.O) posted a quarterly profit below market expectations, hurt by an increase in net-charge offs and provision for loan losses.

For the second quarter, net income was $13 million, or 25 cents a share, compared with $6.5 million, or 6 cents a share, a year ago.

Analysts on average expected the company to earn 38 cents a share, according to Thomson Reuters I/B/E/S.

The company's net interest income rose 44 percent to $104.3 million, but was offset by a spike in its bad loan provisions that rose by 74 percent to $41.3 million.

Net charge-offs rose nearly three-fold to $37.9 million.
