Foreign investors entering mining, energy, and infrastructure projects in Latin America almost always get the commercial terms of an EPC contract right. Where deals actually stall or quietly bleed value for years afterward is in two areas that rarely make it into the term sheet: permitting sequencing and cross-border tax exposure.
Having structured EPC contracts and related acquisitions in both Bolivia and Argentina, we’ve seen the same two failure points recur, almost identically, across both jurisdictions. This article breaks down what they are, why they happen, and how they’re actually solved not in theory, but in the structuring work itself.
What Is an EPC Contract, and Why Does Structure Matter So Much?
EPC stands for Engineering, Procurement, and Construction a single-contract model where one contractor takes turnkey responsibility for designing, sourcing, and building a project. It’s the standard structure for mining, energy, and infrastructure investment across Latin America, which means it’s also where most of the legal and tax risk in these deals concentrates.
The commercial logic of an EPC contract is simple. The legal and tax structuring underneath it usually isn’t especially when the investor is foreign, the contractor is local, and the project sits under a regulatory authority with its own permitting timeline.
Trap 1: Permitting Timing Is Treated as a Formality, Not a Deal Driver
The most common mistake we see: investors structure the corporate deal first, and treat permits and registrations with mining or energy authorities as a downstream administrative step.
In practice, it’s the reverse. Permitting timelines should shape the deal structure not the other way around.
In our work acquiring an EPC contractor for mining projects in Argentina, the acquisition itself was the straightforward part. The real structuring challenge was sequencing the corporate transaction so that mining plot acquisition, entity registration, and the permits required to actually operate were aligned rather than closing a deal on paper and then discovering the target entity wasn’t yet licensed to do the work it was acquired to do.
This is not a Latin America–specific inefficiency. It’s a structural reality of regulated-sector M&A anywhere: the asset you’re buying is only as valuable as its ability to legally operate and that ability is gated by a permitting process the deal timeline needs to be built around, not layered on top of.
Trap 2: A “Clean” Holding Structure That Isn’t Actually Clean
The second trap is subtler, and more expensive when missed: a corporate holding structure that looks tax-efficient on paper but still leaves the foreign investor exposed to local corporate tax or VAT because the exposure lives inside the EPC agreements themselves, not the holding structure.
This is where legal and tax structuring have to happen together, not as sequential handoffs between different advisors. In our fuel supply contract work with a state-owned counterparty in Bolivia, the corporate structuring, tender participation, and tax planning were designed as one integrated process specifically to keep the client’s UAE entity outside the scope of local corporate tax exposure. That result isn’t achievable by structuring the holding company well and then drafting the EPC agreement separately, the exposure has to be designed out of the contract language itself, in coordination with the corporate structure sitting above it.
We’ve since applied the same integrated approach to mining project structuring in Argentina, with tax optimization built into the acquisition and operating structure from the outset not retrofitted once the tax bill arrived.
Why This Pattern Holds Across Jurisdictions
Bolivia and Argentina have different regulatory regimes, different tax codes, and different permitting authorities. What they share is a structural pattern: foreign investors lose value not at the negotiation table, but in the gap between corporate structuring and operational/regulatory reality.
A UAE holding structure, when used correctly, can meaningfully reduce cross-border tax exposure on these deals. But the phrase “when used correctly” is doing real work it depends on the holding structure being designed in direct coordination with the permitting timeline and the EPC contract terms, not as a separate, later-stage tax exercise.
The Practical Takeaway
If you’re a foreign investor evaluating an EPC-structured acquisition in Latin America, the two questions worth asking your legal and tax advisors before signing anything are:
1. Does our deal timeline account for permitting and registration requirements, or assume they’ll follow automatically once we close?
2. Is our tax structuring integrated into the EPC contract terms themselves, or sitting separately at the holding-company level only?
If either answer is unclear, that’s usually where value gets lost, not in the headline deal terms, but in the structuring work that happens (or doesn’t happen) around them.
CMBS Partners has structured EPC contracts, mining acquisitions, and cross-border tax planning across Bolivia and Argentina, combining legal and tax structuring as a single, integrated process rather than sequential advisory steps. If you’re evaluating a similar transaction, we’re glad to talk through the specifics.
