According to the Schedule 13D filed on 5/3/16, TPG currently holds 17,182,136 shares of ENDP. At Friday's closing price of $14.05, TPG's shares of ENDP are worth $241.4 million. The $1.55 billion figure you referenced was the implied value of the stock consideration TPG would receive (18 MM shares x $86.111) for Par as of the transaction announcement date (5/18/15). The implied value of the stock consideration fell to $1.06 billion (18 MM shares x $61.82) as of the closing date for the transaction (9/28/15). Suffice it to say, TPG's position is substantially underwater at the present.
Congratulations on under performing the broad market by 100% over 3+ years. DiSilva is paid like he is delivering alpha, but fails to even deliver beta. A harsh assessment? Yes, but in the words of Coach Bill Parcells - "You are what your track records says you are."
Yes, plus both companies have similar strategies (growth by acquisition) which works in a risk-on environment and when new capital is plentiful. Do a comparison using the interactive chart function from when De Silva became CEO in March 2013 - almost mirror images in terms of the performance.
I did a quick calculation using a constant growth (Gordon) dividend discount model. Assuming future annual dividend growth of 2%, the current stock price of $3.17 implies a new annual dividend rate of approximately $0.16 or a yield of 5.0%
