USA Rare Earth is making a big move in the critical minerals space. The company plans to acquire Brazil’s Serra Verde for $2.8 billion. This deal includes $300 million in cash and 126.9 million new shares. This values Serra Verde at about $2.8 billion based on USA Rare Earth’s share price from April 17. The acquisition is expected to close in the third quarter of 2026.
This purchase connects one of the few heavy rare earth producers outside China with USA Rare Earth’s growing mine-to-magnet platform. It aims to create an integrated supply chain for mining, processing, and magnet manufacturing. This is key as governments and industries want to reduce their reliance on Chinese supplies.
Barbara Humpton, Chief Executive Officer of USA Rare Earth, stated:
“The acquisition of Serra Verde represents a transformational step in delivering on our ambition to build a global champion and the partner of choice in rare earth elements, oxides, metals and magnets. Serra Verde’s Pela Ema mine is a one-of-a-kind asset and the only producer outside Asia capable of supplying all four magnetic rare earths at scale, together with other vital REEs, such as Yttrium. Serra Verde’s global importance is evidenced by its 15-year offtake agreement with a special purpose vehicle capitalized by various U.S. Government entities, as well as private capital sources, for 100% of its Phase 1 Nd, Pr, Dy and Tb production.
By combining Serra Verde’s world-class operations and team with our processing, separation, metallization and magnet-making capabilities, we are advancing our goal of creating a fully integrated platform that will serve as a cornerstone of global rare earth supply security for decades to come.”
Serra Verde Adds Heavy Rare Earth Supply the West Has Been Missing
Serra Verde provides access to heavy rare earths like dysprosium, terbium, and yttrium. These materials are essential for permanent magnets in electric vehicles, wind turbines, robotics, and defense tech. Sourcing them outside China is challenging. Supply concerns are rising as demand grows.
Many Western projects focus on light rare earths, but Serra Verde offers valuable heavy elements. Its Pela Ema mine in Goiás began production in 2024 after over $1.1 billion in investments. It became the first operational ionic clay deposit in the West.
REEs from clay deposits at Pela Ema
- By 2027, Phase 1 is projected to produce about 6,400 metric tons of total rare earth oxide annually. The mine aims to supply over 50% of non-China heavy rare earths by 2027. These figures boost the asset’s strategic value, with growth potential beyond current operations.
- A Phase 2 expansion could double production.
This growth aligns with USA Rare Earth’s goal of building a complete rare earth supply chain. Serra Verde adds feedstock production, while Round Top in Texas offers another source of heavy rare earths. Together, these assets strengthen the upstream supply base. But the story goes beyond mining.
Building a Vertically Integrated Rare Earth Platform
USA Rare Earth has spent years creating a vertically integrated platform. They acquired Less Common Metals in the UK, adding rare earth metal, alloy, and strip-casting capabilities. An Oklahoma magnet plant, launching later this year, will enhance downstream manufacturing.
With Serra Verde, these assets connect Brazilian feedstock, U.S. project development, European metallization, and U.S. magnet production.

Closing the Weak Links in the Supply Chain
According to the U.S. Geological Survey’s Mineral Commodity Summaries 2025, rare earth supply remains highly concentrated, with China continuing to dominate both mining and, more importantly, processing and magnet production.
Thus, this integration is crucial. Supply chain gaps have hindered Western rare earth ambitions. Mines without processing capacity face bottlenecks. Processing without secure feedstock risks supply. Magnet manufacturing without reliable materials can leave operations vulnerable.
This deal addresses these issues by combining multiple stages of the value chain. Strategic highlights from the acquisition show expansion opportunities across nearly every part of the platform.
- Upstream Supply Base: Upstream, Serra Verde’s Phase 2 growth paves the way for larger production volumes, while Round Top adds long-term potential. On the processing side, USA Rare Earth gains separation expertise through its partnership with Carester and plans to develop a rare earth carbonate separation line.
- Processing and Metallization Capacity: In metallization, the company aims to expand Less Common Metals’ reach in France, the U.S., and other markets to increase non-China metal, alloy, and strip-cast output.
- Downstream Magnet Manufacturing: Downstream, management sees potential to grow magnet manufacturing capacity for industrial customers focused on supply security. Together, these initiatives create a strategy that scales the entire supply chain rather than adding isolated assets.
Financial Structure Designed to Reduce Risk and Support Growth
The deal includes financial features aimed at reducing risk while supporting growth. Serra Verde secured a $565 million financing package from the U.S. International Development Finance Corporation to fund expansion through positive cash flow.
This eases financing pressure and supports scaling. It also has a 15-year, 100% offtake agreement for neodymium, praseodymium, dysprosium, and terbium, with minimum price floors, improving revenue stability and limiting commodity price risk.
Serra Verde expects $550–650 million in annualized EBITDA by 2027, with the combined company targeting about $1.8 billion by 2030 and roughly 80% cash flow conversion. The projections underline the deal’s transformational nature, focused on earnings growth and supply chain resilience.
USA Rare Earth (USAR) Stock Jumps 15%
Meanwhile, USA Rare Earth secured a separate $1.6 billion funding package from the U.S. government earlier this year. The company expects more than $3.2 billion in pro forma liquidity, which includes around $1.2 billion in cash and $1.8 billion from milestone-based funding. This funding comes from DFC and the U.S. Department of Commerce loan facilities.
This government support shows that rare earth supply connects to industrial strategy and national security. Governments see critical mineral supply chains as essential for energy, advanced manufacturing, and defense. The deal’s financing reflects this change and improves the company’s financial outlook.
Significantly, USA Rare Earth (USAR stock) shares rose over 15% after the announcement, boosting the company’s market value to about $4.9 billion.
Overall, this acquisition marked a shift in how the Western rare earth industry approached supply security. Instead of relying on isolated mining projects, USA Rare Earth moved toward a fully integrated platform that connected mining, processing, metallization, and magnet manufacturing across multiple regions.
The deal strengthened access to heavy rare earths, improved supply chain control, and aligned closely with government-backed industrial strategy. While execution risks remained, the overall direction pointed clearly toward building a more secure and independent rare earth supply chain outside China.

More and more small and medium-sized businesses are hearing the same question from their larger customers: What is your carbon footprint? That question now travels down entire supply chains, and it arrives next to tender requirements, certification criteria, and rising customer expectations.
The accounting differences that decide whether your nature investment shows up in inventory, in BVCM, or nowhere at all.
The question reaches a procurement team about three weeks before the next sustainability committee meeting. Someone has read about insetting. Someone else has just signed off on an offset purchase. The CSO wants to know if the two are interchangeable. The answer is no, and the GHG Protocol Land Sector and Removals Standard is the reason why.
This article walks through what each term means at audit-grade specificity, what the standards actually say about how each gets counted, and how to decide which tool fits which target. The insetting vs offsetting question is one of the most-searched in corporate climate strategy, and one of the most poorly answered. By the end of this piece, you should be able to brief a committee on the difference without notes.
The two definitions, in plain English
Offsetting means buying carbon credits generated outside your value chain and retiring them against your residual emissions. The reduction happens somewhere else, financed by you, and the credit is the receipt.
Insetting means investing in emission reductions or removals inside your own value chain, typically with suppliers, where the reduction is directly linked to the products and services you buy. The reduction happens inside the boundary of your Scope 3 inventory, and the accounting treatment is fundamentally different.
The shorthand from the University of Oxford’s Nature-based Insetting Initiative is useful: insetting is what you do with the supply chain you have; offsetting is what you do with the supply chain you do not have.
What the GHG Protocol Land Sector Standard actually says
The GHG Protocol Land Sector and Removals Standard, finalised in 2024 after a multi-year pilot, sets the rules for how land-based emission reductions and removals enter corporate inventories. The Standard distinguishes between inventory accounting (Scope 1, 2, and 3) and project or intervention accounting (a separate methodology for crediting).
For insetting, the practical implication is that supplier-level interventions, when properly measured and attributed, can reduce your Scope 3 category 1 (purchased goods and services) emissions in your inventory. The reduction is not a credit retired against the inventory; it is a lower inventory number, period.
For offsetting, the credit is retired separately. It can be reported as a contribution toward a net-zero claim under the SBTi Beyond Value Chain Mitigation framework or as part of a VCMI Carbon Integrity claim, but it does not lower the inventory number.
A practical consequence: if your Science Based Target requires a 50% absolute reduction in Scope 3 emissions by 2030, insetting moves you toward the target. Offsetting does not. This single point of difference reshapes the procurement decision.
When insetting counts toward Scope 3 (and when it does not)
Insetting counts toward Scope 3 only when several conditions are met:
- The intervention must occur with an entity in your value chain.
- The emissions reduction or removal must be measured against a defensible baseline.
- The reduction must be attributed to your share of that supplier’s output, not double-counted with other buyers.
- It must follow the inventory accounting rules in the GHG Protocol Land Sector Standard, not the project accounting rules used to generate credits.
The most common failure mode is double counting. If your supplier sells the same reduction as a credit on the voluntary market and also reports it to you as a Scope 3 reduction, the math breaks. The Standard requires you to address this risk, typically by purchasing and retiring the supplier-issued credit as part of your inventory or by contractual provisions that prevent the supplier from selling the reduction twice.
When insetting does not count toward Scope 3: when the intervention sits with a supplier you do not buy from, when the baseline is not defensible, when the attribution is unclear, or when the documentation does not survive audit. Those cases default to Beyond Value Chain Mitigation, which is still useful but operates on a different ledger.
The procurement and supplier engagement question
Insetting is harder than offsetting. That is the unfashionable truth most buyers eventually confront. Offsetting is a transaction; insetting is a relationship.
To run an insetting program, you need supplier mapping precise enough to know which farms or facilities sit at which Scope 3 boundary. You need an engagement model that gets suppliers to participate, which usually requires multi-year commitments and shared economics. You need an MRV architecture that measures the right things and produces audit-ready documentation. And you need a contractual structure that prevents double counting and protects both sides.
The trade-off you receive in return is significant. Reductions count against your inventory rather than your residual. Supplier relationships deepen, which protects sourcing continuity. Yield and quality improvements often follow regenerative interventions, which reduces your input cost over time. And the regulatory file, under CSRD, CSDDD, EUDR, and the SBTi FLAG Guidance, is materially stronger.
Choosing the right tool for the right target
A practical decision rule. If your target is a science-based Scope 3 reduction and you operate in a FLAG sector or source FLAG commodities, insetting is the structurally correct tool. If your target is a net-zero claim that includes neutralising hard-to-abate residual emissions outside your value chain, BVCM via high-integrity offsets is the structurally correct tool. Most companies with material Scope 3 exposure need both, in different proportions, sequenced over time.
The sequencing matters. Insetting takes longer to stand up but produces a permanent reduction in the inventory. Offsetting can be transacted faster but does not change the inventory and now sits under tighter claim restrictions. Treat them as complementary tools with different jobs, not as substitutes. The Accountability Framework Initiative and the IUCN Global Standard for Nature-based Solutions both provide useful guardrails for the insetting side, with biodiversity, human rights, and benefit-sharing requirements that go beyond carbon math.
If you are mapping a Scope 3 reduction roadmap and need to scope which interventions count toward your inventory versus which sit in Beyond Value Chain Mitigation, the carbon and sustainability experts at Carbon Credit Capital can help you structure a nature-based supply chain investment program that fits your FLAG exposure, your target architecture, and your audit horizon. Schedule a consultation.
Net zero is often described as a balancing act: cut what you can, account for the rest, and reach zero on the ledger. That framing is useful, but it leaves something out. It treats every tonne of carbon as interchangeable and every route to zero as equally sound, while the science tells a more specific story.
