Advent International has agreed to purchase Charlotte Russe for $17.50 a share, or about $380 million. The sale price is well above the original takeover offer of $9 to $9.50 a share from KarpReilly and H.I.G. Capital in November, a deal that was rejected by the company resulting in criticism from shareholders. Charlotte Russe, a retailer of women's clothing with approximately 500 stores, has been open to sale since January and has retained Cowen & Company as its financial advisor. The company began seeking a buyer in March.
