In June last year, the SFO filed criminal charges against the FTSE 100-listed lender and four of its former top executives for their handling of Middle Eastern investments that helped save the bank at the height of the financial crisis.
In a statement on Monday, Barclays revealed that two of the charges against it - for conspiring with former senior officers and employees of the company to commit fraud by false representations relating to advisory services agreements entered into with Qatar Holding LLC in 2008 - were dismissed.
It added that other charges against Barclays and its investment banking business for unlawful financial assistance regarding a US$3bn loan to Qatar in November 2008 were also dismissed.
The bank, however, said that the SFO is likely to try and re-instate the charges by applying to a High Court judge to re-commence proceedings via a new indictment.
In early afternoon trading, Barclays shares in London were 1% higher at 209.55p.
