ENTERPRISE FINANCIAL COMPLETES $35.0 MILLION

PUBLIC COMMON STOCK OFFERING

St. Louis, May 24, 2011. Enterprise Financial Services Corp (NASDAQ: EFSC) announced today that it has raised approximately $35.0 million through a previously announced underwritten public offering of 2,743,900 shares of its common stock, including 357,900 shares issued pursuant to the exercise of the underwriter’s over-allotment option, at a public offering price of $12.75 per share.

The net proceeds to the Company, after deducting underwriting discounts and commissions and estimated offering expenses, are expected to be approximately $32.5 million. The net proceeds from the offering will be used to further strengthen the Company’s capital position and for other general corporate purposes, which may include capital to support growth and acquisition opportunities.

“We are very pleased with the strong response to the offering,” commented Peter Benoist, President and CEO of Enterprise Financial. “This additional capital enhances our already strong capital levels and positions us well for future growth as our momentum continues to build. Each of our holding company board members also participated, which is a tremendous expression of their confidence in the company and its future.”

Keefe, Bruyette & Woods, Inc.acted as sole book-running manager of the offering. The shares in the offering were issued pursuant to a prospectus supplement filed with the Securities and Exchange Commission as a part of the Company’s effective shelf-registration statement on Form S-3 (File No. 333-160032). This announcement shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any offer or sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

Enterprise Financial operates commercial banking and wealth management businesses in metropolitan St. Louis, Kansas City and Phoenix. Enterprise is primarily focused on serving the needs of privately held businesses, their owner families, executives and professionals.
