Wood Mackenzie provides two types of offerings to its customers:

Key secular demand drivers for data analytics in the energy sector include the need for companies in the oil and gas industry to have data analytics available to make decisions — such as where to drill, how to prioritize their drilling projects, how much capital to spend and how to manage their asset portfolios. In 2013, the global oil and gas industry is estimated to have spent more than $600 billion on upstream capital expenditures and has trillions of dollars invested in energy assets that they must manage and optimize. Verisk Analytics, Inc. (the “Company”) believes that this large amount of investment is managed more efficiently with Wood Mackenzie data analytics. Companies also need advisory services to help them value their assets, be it an oil field, coal mine or liquefied natural gas project. Financial companies and banks also need information about these assets and their valuation in order to advise their customers, make loans and decide about investments in the oil and gas space.

Wood Mackenzie provides its customers with access to its subscription based data/analytics services primarily through annual or multi-year subscriptions. Such subscriptions are typically paid upfront and have been renewed at rates greater than 95% (by value) during 2010-14. Subscription revenues represented over 80% of the Wood Mackenzie revenues in 2014. As a result of this subscription-based business model, Wood Mackenzie generates a significant amount of recurring revenues, and there is strong visibility into Wood Mackenzie’s future revenues and cash flows.
