| Source: Enterprise Financial

ST. LOUIS, April 2, 2012 (GLOBE NEWSWIRE) -- Enterprise Financial Services Corp (Nasdaq:EFSC) announced today that, as expected, it had received a notice from The NASDAQ OMX Group ("NASDAQ") indicating that the Company is not in compliance with the continued listing requirements under NASDAQ Listing Rule 5250(c)(1) because the Company did not timely file its Annual Report on Form 10-K for the year ended December 31, 2011. The NASDAQ notice has no immediate effect on the listing or trading of the Company's common stock on the NASDAQ Global Select Market.

As previously reported in a Form 12b-25 Notification of Late Filing made by the Company on March 15, 2012, the Company is delayed in the filing of the Form 10-K because of the need to restate its financial statements for the year ended December 31, 2010 and the interim financial statements included in its Quarterly Reports on Form 10-Q as of and for each of the periods ended March 31, June 30, and September 30, for 2010 and 2011, respectively.

On January 25, 2012, the Company announced that it will restate its financial statements as a result of an accounting error it discovered related to the calculation of income on loans covered by FDIC loss share agreements. As indicated in that announcement and based on current estimates, the Company expects to report net income of between $1.20 and $1.35 per diluted share for the year ended December 31, 2011. In addition, the Company expects to report continuing favorable trends in its core banking business, including a 29% increase in organic Commercial and Industrial loans for 2011 and a 19% reduction in nonperforming assets to 1.74% of total assets. The Company's principal subsidiary, Enterprise Bank & Trust, remains "well-capitalized" under all regulatory definitions.

The Company believes it will announce its 2011 fourth quarter and year-end financial results and file its Form 10-K no later than April 25, 2012.

The Company is required to submit a plan to regain compliance with NASDAQ's filing requirements for continued listing within 60 calendar days of the date of the NASDAQ notification letter. The Company anticipates that it will fully regain compliance with the NASDAQ continued listing requirements upon filing its Form 10-K and that the filing of the Form 10-K within the 60-day period will eliminate the need for the Company to submit a formal plan.
