Rosetta Stone Inc., a maker of language-learning software, jumped the most in 2 1/2 years Friday after the company said it received an “expression of interest” from RDG Capital Fund Management.
Rosetta Stone rose 19 percent to $7.62 at the close in New York trading, the biggest one-day gain since November 2012. The shares have lost 22 percent this year.
The board “will carefully evaluate the expression of interest,” Arlington, Virginia-based Rosetta Stone said in a statement. Kendell Moore, a spokeswoman for Rosetta, declined to comment beyond the statement.
Founded in 1992, the company offers courses in 30 languages. The board also said it is implementing a strategic plan to deliver value to shareholders, according to the statement.
