INTERNATIONAL ASSETS HOLDING CORPORATION REPORTS

2010 FISCAL THIRD QUARTER FINANCIAL RESULTS

New York, NY – August 12, 2010 – International Assets Holding Corporation (the ‘Company’; NASDAQ: IAAC) today announced its fiscal 2010 third quarter financial results for the three and nine months ended June 30, 2010. Certain financial metrics discussed in this press release are non-GAAP, reflecting marked-to-market differences in the Company’s Commodity & Risk Management Services segment. A reconciliation of those metrics to GAAP equivalents is provided in the table below, and further discussion of the use of non-GAAP metrics is provided in the Company’s Form 10-Q, to be filed with the Securities and Exchange Commission (“SEC”).

Sean O’Connor, CEO of International Assets, stated, “A slight improvement in market conditions resulted in fully diluted EPS of $0.48 on continuing operations (adjusted EPS on a marked-to-market basis of $0.27). During the quarter we believe we made significant progress in expanding our capabilities with the acquisition of Hanley Group which, together with our physical and exchange expertise, gives us a unique product offering for our commercial customers and should serve to drive profitability in the medium and long term.”
