Nasdaq Stockholm AB: Decision by Nasdaq Stockholm's Disciplinary Committee

The Disciplinary Committee of Nasdaq Stockholm (the "Exchange") has found that
Citigroup Global Markets Europe AG (the "Company") has breached the Nasdaq
Nordic Member Rules (the "Rulebook") and therefore ordered the Company to pay a
fine of SEK 6,000,000. 

On May 2, 2022, the Exchange's Trading Surveillance function identified a
significant price drop in a number of financial instruments and indices,
including equities, futures and Exchange Traded Products (the "Market Event")
traded on markets operated by Nasdaq Nordic. The price drop lasted for
approximately seven minutes before correcting to roughly the same levels as
before the drop. During the price drop, the indices in Denmark, Finland and
Sweden were down approximately 6.5%, 7% and 8%, respectively. The Exchange's
analysis showed that the Company was the major seller in the market, and
thereby triggered the Market Event. 

The Exchange argued before the Disciplinary Committee that the Company violated
the Rulebook by not having in place sufficient pre-trade controls, by
submitting non-genuine orders to the Exchange, by failing to properly monitor
its trading activity, by failing to keep contact information provided to the
Exchange up to date and by not immediately notifying the Exchange of a material
deviation from the provisions of the Rulebook. 

The Disciplinary Committee states that it is evident that the Company's trading
control system did not prevent an individual trader from executing erroneous
orders with a total value of 189 billion dollars, and that the warnings the
trader received in the system could easily be dismissed. According to the
Disciplinary Committee, the Company did not have the required trading control
systems considering the nature and scope of its operations. The Disciplinary
Committee sees no reason to doubt that the Market Event was initiated and
predominantly caused by the actions of the Company's trader and the
deficiencies in the Company's control system. 

The Disciplinary Committee notes that the Company has violated five sections of
the Rulebook. The Disciplinary Committee takes a particularly serious view of
the deficiencies in the Company's internal control and the effects that the
erroneous orders on May 2, 2022, as far as can be assessed based on the case
material, had on the market. The Disciplinary Committee sets the fine at SEK
6,000,000.
