          Item 9)

The  following  information  is  being  provided  under  Item  12 -  Results  of
Operations and Financial  Condition.  It is being furnished under Item 9 of this
Form 8-K in accordance  with interim  guidance  issued by the SEC in release No.

On July 15, 2003,  Trustmark  Corporation  issued a press release announcing its
financial  results for the period  ended June 30,  2003.  This press  release is
attached as Exhibit 99.1 to this report and incorporated herein by reference.

Included  in  Note  2 to  the  Consolidated  Financial  Information  is  certain

Accounting  Principles,  except that the financial  effects of Trustmark's early
retirement  program  during the first  quarter have been  excluded  (net income,
earnings  per  share and  selected  financial  ratios).  We have  provided  this
