My new MMX valuation is A$9.04/sh which includes the Mitsubishi deferred payment equivalent to A$3.97/sh.
My calculation is shown below.
MMX - valuation
Base case valuation at a discount rate of 9.88% (WACC of 7.88% plus 2% for approval and environmental risk) A$5.07/sh up from A$4.40/sh for its 50% share of the mining and infrastructure project.
Deferred payment - Mitsubishi has agreed to pay MMX to earn a 50% equity interest in the project before construction commences in Jun H.'09 a sum based on the NPV of the project less half the initial payment of A$150M. We value the project (100%) at A$4,158M at a discount rate of 9.88%. MMX could receive a payment for 50% as follows:
Project value (NPV) A$4,158M (Dec.H'08).
Initial payment A$150M
Equity contribution A$800M assuming a capital cost of A$2B for the project
