Private equity firm Veritas Capital is buying educational publisher Houghton Mifflin Harcourt for $2.8 billion in cash, HMH announced yesterday.

The sale comes a little less than a year after Houghton Mifflin Harcourt sold its trade division to HarperCollins for $349 million. Per the Boston Globe, HMH’s shares have nearly tripled in the past year, giving it a market value of close to $2.3 billion. Recently the publisher, which dates back to 1832, has pivoted from textbooks to educational services that include online components.
