Renewable energy M&A in Thailand tends to look simple to buyers the moment they see a signed power purchase agreement running twenty years and a BOI certificate attached to the target. It reads like the easiest business you could buy: revenue is contracted, the counterparty is usually a state utility, and the story practically writes itself. That relief is where the mistake starts.

A renewable energy asset is not really an operating business with customers and margins that grow or shrink with the market. It is a contract, wrapped in a legal entity, sitting on a piece of land. The company’s income statement is a byproduct of what one agreement says, not the result of decisions a management team makes about pricing, customers, or competition. Once you accept that, the entire structuring and valuation conversation has to change, and most buyers do not make that shift early enough. This is the same discipline I apply to every transaction I structure, regardless of sector, but it matters more here because once you strip away the contract, there is nothing else in the business to analyze.

Start with revenue recognition and cash flow. A normal acquisition target has revenue that moves with volume, price, and mix, and a buyer builds a model by projecting those drivers forward from a trend. A renewable asset does not work that way. The cash flow is close to a fixed schedule set by the tariff structure in the PPA, and the only real variables are curtailment, degradation, and whether the rate is fixed, escalating, or a premium on top of a wholesale price that still moves. Building a standard growth model on top of that kind of cash flow gets the valuation wrong before you even get to a discount rate, because you are modeling the wrong kind of uncertainty. The real question is not how fast will this grow. It is how solid is this specific cash flow stream, for how many years, under what conditions.

That is why the specific clauses in the agreements matter more here than in almost any other kind of deal. In most acquisitions, the contract terms are a legal workstream that runs in parallel with the financial analysis. In a renewable deal, the contract terms are the financial analysis. The change of control clause in the PPA determines whether the revenue stream you are valuing actually transfers with the shares you are buying, or whether it needs the offtaker’s consent first. The termination and step-in rights determine what happens if something goes wrong operationally, and who gets to fix it. The tariff clause, fixed, escalating, or Adder-style premium, determines whether you are buying a bond-like cash flow or something with real market exposure baked in. None of this shows up by reading the financial statements. It shows up by reading the contract, line by line, before you build the model, not after.

Reading the contracts this early changes more than your risk assessment. It changes your negotiating position. A seller pricing the asset off a clean, uninterrupted revenue history has every incentive to let the buyer assume the PPA and BOI status simply carry over. If your team has already identified that the change of control clause requires the offtaker’s consent, or that the BOI conditions include an ownership threshold your proposed structure would breach, you are negotiating from a position the seller did not expect you to reach before signing an exclusivity agreement. Buyers who wait until due diligence to find this out have usually already agreed to a price and a structure that assumed none of it existed.

This changes how the deal itself should be structured. Whether you buy shares or buy the asset directly affects whether the PPA and the BOI promotion carry over automatically or need to be renegotiated and reapplied for. It affects who bears the risk if a clause turns out to be less favorable than the seller represented. It affects how the deal gets financed, because a lender underwriting against a fixed contracted cash flow will look at the same change of control and step-in provisions you are looking at, and price its debt accordingly. These are not questions to answer during due diligence. They are questions that should shape how due diligence gets scoped in the first place.

My recommendation is direct. Before you talk price, before you build the model, and before you scope diligence, get the PPA, the financing agreements, and the BOI certificate read together by someone who understands deal structure, not just contract law. The valuation, the financing, and the structure you choose all flow from what those documents actually say, not from the summary in the information memorandum. Boards that skip this step end up negotiating price on assumptions that the contracts themselves do not support.

If you sit on the board or investment committee approving a deal like this, ask one question before you approve anything: has anyone confirmed, from the actual contract text, that the revenue stream we are pricing this asset on transfers cleanly under the structure being proposed. If the answer is a summary from an information memorandum rather than a specific clause reference, the question has not actually been answered yet.
