ASC 606 Investor Presentation June 7, 2018 Exhibit 99.1

Multi-year contracts with ramping fees: In multi-year arrangements with ramping fees (e.g., Year 1 fees of $1M, Year 2 fees of $2M, and Year 3 fees of $3M), 606 dictates that revenue be recognized equally over each year of the arrangement. Relative to 605, more revenue (which will be unbilled) will be recognized in early years of the arrangement and less revenue in later years. Application of this treatment depends on the terms of the customers’ arrangements. Capitalized commissions: We previously expensed commissions the period in which they were incurred. Going forward, we will capitalize commissions and amortize them over a 3-year term. Calculated billings: Under 606, the billings calculation changes to account for unbilled receivables. New formula à Calculated billings = Revenue + change in deferred revenue – change in unbilled receivables. Using this formula, there is minimal change to calculated billings. No change to cash flows Primary impacts from 606 transition FY17 & FY18 have been restated under the full retrospective method

Total revenue ($M) YOY growth: 25% YOY growth: 26% All 606 impacts are in subscription revenue; services revenue is unchanged
