Citigroup’s largest individual investor, Saudi Prince Al Waleed Bin Talal, said he plans to stick by the embattled bank and offered praise for Citi’s plans to pay back Uncle Sam.

He may be the only one.

Citi’s stock sank 5 percent in midday trading to $3.74 after the financial giant announced it has finally reached an agreement with the Uncle Sam to pay back $20 billion it received in bailout aid.

There have been concerns about stock dilution as well as questions as to whether Citi’s really ready to get off life support or simply competing with the Joneses. Citi’s repayment plan came right on the heels of a similar announcement by beleaguered Bank of America.

“Although Citigroup’s negotiations with the US government have taken some time, today’s announcement gives Citigroup more certainty as to how they will conduct their business profitably,” the prince said in a statement issued by his Kingdom Holdings investment vehicle.
