FOR IMMEDIATE RELEASE – Birmingham, Alabama (October 23, 2007) – Alabama National BanCorporation (“ANB”) (NASDAQ/Global Select Market: ALAB) today announced earnings for the quarter and nine-month period ended September 30, 2007.

For the 2007 third quarter, ANB reported net income of $19.8 million, or $0.95 per diluted share. Nine months year-to-date net income was $61.8 million, or $2.96 per diluted share. As previously reported, ANB sold its ANB Insurance Services, Inc. subsidiary during the 2007 second quarter. Earnings from the operation of this subsidiary and the gain from its sale are carried as income from discontinued operations in the income statement.

Excluding the discontinued insurance operations from all periods, ANB reported earnings from continuing operations of $19.8 million in the 2007 third quarter, down 6.1% from the $21.1 million earned in the 2007 second quarter and down 1.4% from the 2006 third quarter’s $20.1 million in net income from continuing operations. Diluted earnings per share (continuing operations) of $0.95 in the 2007 third quarter were 5.6% below the $1.01 reported in the 2007 second quarter and 9.7% below the $1.06 reported in the year ago third quarter. Diluted cash earnings per share (continuing operations) were $0.99 in the 2007 third quarter, as compared with $1.05 and $1.10 in the 2007 second quarter and 2006 third quarter, respectively.

For the nine months ended September 30, 2007, ANB’s $60.6 million in income from continuing operations equated to $2.91 in diluted earnings per share, down 5.8% from the $3.09 earned in the first nine months of 2006. Year-to-date revenue for the first nine months of 2007 was $253.7 million, up 13.1% from the 2006 nine months.

Holcomb III, Chairman and CEO. “Our planning efforts with our new partner are focused on ensuring a smooth transition for our customers as we prepare to introduce additional products and services as part of the RBC family.”

Conference Call:

Alabama National will not be holding a conference call this quarter to discuss these results.

Many of the comparisons of financial data from period to period presented in the narrative of this release have been rounded from actual values reported in the attached selected unaudited financial tables. The percentage changes presented above are based on a comparison of the actual values recorded in the attached tables, not the rounded values.

This press release, including the attached selected unaudited financial tables which are a part of this release, contains financial information determined by methods other than in accordance with generally accepted accounting principles (“GAAP”). These “non-GAAP” financial measures are “cash earnings” (cash earnings per share), “tangible book value” (tangible book value per share), “return on average tangible equity” and “return on average tangible assets.” ANB’s management uses these non-GAAP measures in its analysis of ANB’s performance. Cash earnings is defined as net income plus amortization expense (net of tax) applicable to intangible assets that do not qualify as regulatory capital. Cash earnings per basic and diluted share is defined as cash earnings divided by basic and diluted common shares outstanding. ANB’s management includes cash earnings measures to compare the company’s earnings exclusive of non-cash amortization expense and because it is a measure used by many investors as part of their analysis of ANB’s performance. Tangible book value is defined as total equity reduced by recorded intangible assets. Tangible book value per share is defined as tangible book value divided by total common shares outstanding. This measure is important to many investors in the marketplace that are interested in changes from period to period in book value per share exclusive of changes in intangible assets. Goodwill, an intangible asset that is recorded in a purchase business combination, has the effect of increasing total book value while not increasing the tangible assets of the company. For companies such as Alabama National that have engaged in multiple business combinations, purchase accounting requires the recording of significant amounts of goodwill related to such transactions. Return on average tangible equity is defined as annualized earnings for the period divided by average equity reduced by average goodwill and other intangible assets. Return on average tangible assets is defined as annualized earnings for the period divided by average assets reduced by average goodwill and other intangible assets. ANB’s management includes these measures because it believes that they are important when measuring the company’s performance exclusive of the effects of goodwill and other intangibles recorded in recent acquisitions, and these measures are used by many investors as part of their analysis of ANB. These disclosures should not be viewed as a substitute for results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures which may be presented by other companies. Refer to the “Reconciliation Table” in the attached unaudited financial tables for a more detailed analysis of these non-GAAP performance measures and the most directly comparable GAAP measures.

Such forward-looking statements are necessarily estimates reflecting the best judgment of ANB’s senior management based upon current information and involve a number of risks and uncertainties. Certain factors which could affect the accuracy of such forward-looking statements are identified in the public filings made by ANB with the Securities and Exchange Commission, and forward looking statements contained in this press release or in other public statements of ANB or its senior management should be considered in light of those factors.
