"The value of a company is based on how much revenue it can produce"... So if Laidlaw was to be liquidated, it wouldn't be worth anything because it hasn't produced any revenue? Give me a break, talk about flawed assumptions...
The value of a company is the discounted value of its after tax cash flow , usually over a 10 or 20 year period. The discounting rate to be determined by reference to underlying riskless returns at the time in question ( long bond yields) plus an equity risk premium.
The value of LLEG therefore is our best forecast of those discounted numbers over the time horizon we decide on.
Value is prospective cash flow discounted back to the present time.
My point is that we don't know what the value of that stream of income will be but unless every project does badly it is in my opinion very unlikely to be less than the current market cap.
That is the way companies are valued Harold in the real GROWN UP world.
