I've only seen a couple of models from way back, but they are quite detailed and complex.
I certainly haven't seen the models that underpin these latest reports.

They generally do a SOTP DCF model, with a huge bunch of varied assumptions, usually measured against or in addition to industry EV/EBITDA multiples.
I.e Goldman Sachs use DCF and EV/EBITDa multiple. generally 85% / 15%:

• APLNG 50/50 on DCF and 6.0X EV/EBITDA
• Energy Markets (inc. corporate) 16.4 P/E multiple
• E&P DCF

A lot of the broker reports will include a fair bit of comms on their main drivers and assumptions.
I note a wide range of WACC employed by brokers, which can impact valuations quite dramatically

If there's anything specific you are after, I can dig it up (or at least try)

I certainly wouldn't blindly follow a broker, but I think consensus is a reasonable indicator. I guess its just another valuation perspective to agree or disagree with

Looking at the following chart of TP Vs closing price wont give you any confidence
