TMX Group, the Toronto-based market operator and data and an analytics provider, has agreed to acquire Boston-based Wall Street Horizon (WSH), a corporate event data provider. The acquisition will extend the global reach of TMX Datalinx’s listed company corporate action and event data offering.

“We’ve done well with the distribution of our core content, and we want to strengthen and deepen that content and expertise,” says Michelle Tran, President, TMX Datalinx. “Purchasing Wall Street Horizon will allow us to expand and grow by adding depth and breadth to that content. Also, we really like the management team, so we’re acquiring not only the content, but the talent as well.”

WSH provides traders, portfolio managers, academics and others a set of forward-looking and historical corporate event datasets, including earnings dates, dividend dates, options expiration dates, splits, spinoffs and a wide variety of investor-related conferences. Covering 9,000 publicly traded companies worldwide, the company offers more than 40 event types.

“For key trends like ESG, indexes or benchmarks, you can create some pretty unique thematics from earnings data, dividends data, and so on,” says Tran. “WSH provides a foundation on which we can build out analytics or other index and benchmark capabilities.”

In the short term, things won’t change too much for WSH customers, says Tran. “For the branding, we will keep it as Wall Street Horizon, a TMX Group company. Over time, we’ll look at a fuller integration, either from a technology perspective, or how WSH becomes an additional line to our end of day corporate action product.”

Completion of this transaction is expected to close in Q4 and is subject to customary closing conditions. D.A. Davidson – whose previous transactions included the sale of Atrium Network to TMX Group, as well as subsequently advising TMX Group on the sale of Atrium to ICE Inc – acted as exclusive financial and strategic advisor to WSH.
