首次公开募股
On September 23, 2008, Rosetta Stone Inc. filed an Initial public offering with the Securities and Exchange Commission. On April 15, 2009, the company was listed as the Rosetta Stone on the New York Stock Exchange, raising $112 million in its initial public offering of stock shares. In its first full day of trading on the New York Stock Exchange, the stock gained 39% from its opening price. After a strong opening, however, the stock stumbled amid reports of weaknesses in Rosetta Stone's US business, resulting in the cancellation of a second offering, and a disappointing year end price just 5 cents off its opening price. The stock trades under ticker symbol RST. As of December 2015, the stock was at approximately $29.2 (USD) per share.
