TABLE OF CONTENTS

### WHERE YOU CAN FIND MORE INFORMATION
We file annual, quarterly and current reports, proxy statements and other information with the SEC. The SEC maintains an internet site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC, including us. The SEC’s internet site can be found at http://www.sec.gov. We make available free of charge most of our SEC filings on the investor relations page of our website at http://www.wintrust.com as soon as reasonably practicable after we electronically file these materials with the SEC. You may access these SEC filings on our website. Except for those SEC filings incorporated by reference in this prospectus, none of the other information on our website is part of this prospectus.

We file annual, quarterly and current reports, proxy statements and other information with the SEC. The SEC allows us to “incorporate by reference” into this prospectus the information we file with the SEC, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is considered to be part of this prospectus, and information that we file later with the SEC that is incorporated by reference herein will automatically update and supersede this information. SEC rules and regulations also permit us to “furnish” rather than “file” certain reports and information with the SEC. Any such reports or information which we have indicated or indicate in the future as being “furnished,” including any information furnished under either Item 2.02 or Item 7.01 or any related exhibit furnished under Item 9.01(d) of any Current Report on Form 8-K unless, and except to the extent, specified in any such Current Report on Form 8-K or in any applicable prospectus supplement, shall not be deemed to be incorporated by reference into or otherwise become a part of this prospectus, regardless of when furnished to the SEC. We incorporate by reference the following documents we filed with the SEC (file number 001-35077) and any future filings that we make with the SEC under Sections 13(a), 13(c), 14, or 15(d) of the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act, until the offerings of the securities contemplated by this prospectus are terminated:
