The sale of Vyleesi could be material for PTN, but without financial details, it's difficult to predict the exact impact on the stock price. The deal could be seen as positive if Vyleesi was not a core asset or if the sale allows PTN to focus on more promising areas. However, if Vyleesi was a significant revenue driver, the sale might be viewed negatively. The lack of disclosed terms adds uncertainty, hence a neutral score is given.
