Swiss exchange operator SIX has purchased its second data provider within the space of a few months under new head of data, Marion Leslie.

SIX is taking over U.K.-based index and exchange traded funds data specialist Ultumus, the Swiss exchange operator said in a press release Tuesday.

SIX added that the transaction closed on Monday. It did not give any financial details.

Covering 95 Percent of Market

Ultumus and SIX have been long-time partners on the index-business side.

Ultumus is one of the largest ETF calculation houses in the world, covering around 7,700 ETF products, accounting for 95 percent of the market, the statement said.

Canadian Acquisition

Ultumus marks the second acquisition by SIX’s head of financial information, Marion Leslie, since February when the exchange operator took a majority stake in Canadian sustainability platform Orenda.

SIX said the aim of the Ultumus takeover was to enhance its data offering and to support its overall strategy to bring new data to its clients in a fast growing market.

«With Ultumus we have found the right partner with unique expertise in ETFs and managed data services. The combination of our capabilities will enable us to provide market-leading services to support our customers in the ETF market,» Leslie said in the statement.
