Shares of Marketo Inc spiked sharply higher, as chatter moved through trader circles that the company was exploring a sale. Bloomberg then came out and said the company had hired advisors to explore a potential sale or strategic alternatives. Credit Suisse released a note after Tuesday's closing bell speculating on what a possible Marketo takeout offer could be. Using acquisitions in the past 12 months, such as Opower, Taleo, WebEx and Yodlee, among others, Credit Suisse plotted the takeout multiples vs. some of these past acquisitions and calculated a trend model that best fit the data points. Applying the $198.9 million sub. revenue and growth of 38.1 percent, Credit Suisse calculated enterprise value of $44.35 per share. Adding and subtracting standard error, they arrived at a range of $37.03 To $51.67 per share, respectively.
