Nasdaq OMX Armenia provided services to Iran and Iran's state-owned Bank Mellat, it said.

"The settlement amount reflects OFAC's determination that Nasdaq's conduct was non-egregious and voluntarily self-disclosed," OFAC said.

Nasdaq said in an emailed statement that the settlement acknowledged mitigating factors, including Nasdaq's voluntary disclosure of the transactions in 2014 and its sale of the Armenian subsidiary in 2018.

Nasdaq acquired the Armenian Stock Exchange, subsequently renamed Nasdaq OMX Armenia, when it acquired Swedish financial company OMX AB in February 2008.
