At the opening keynote of the company's annual industry analyst summit, COO Oliver Ratzeberger displayed a chart showing share prices up almost 40% over the past year, and or almost double over that of a couple years ago. Wall Street likes the fact that Teradata's subscription business is ramping up much faster than expected, accounting for over 60% in Q1 vs. the 40 - 50% that was expected. Mind you, Teradata is pulling off this transition while remaining publicly-traded, unlike midsized software counterparts like Tibco and Informatica that felt the need to go private. Beneath the surface, Teradata has made a number of changes to its business that have facilitated the transition to subscription. Many of those pieces were announced last year.
