RE:PTA: The 5 Potential Suitors and the reasons One more remark. Amerisur Resources (AMER.L) is 100% dependent on one Block in the Putumayo Basin and one oilfield (Platanillo), so they know very well that they must diversify as soon as possible.
And since Amerisur's EV is very high, AMER.L can pay with shares. This is typical for the companies with high EV.
I think PTA shareholders do not care whether they are paid in cash or shares. The acquisition price only matters.
