Companhia Siderúrgica Nacional (SID): Business Model Canvas [Dec-2025 Updated]

You're digging into the Business Model Canvas of Companhia Siderúrgica Nacional (SID), and what you'll find is a textbook example of industrial might battling financial reality. As someone who's spent two decades mapping these behemoths, I can tell you their core strength is absolute control: they run the whole show from the iron ore mine to the finished steel product. Still, the numbers from late 2025 paint a clear picture: they booked a solid R$ 33.39 billion in net revenue for the first nine months, but that massive debt is the elephant in the room, reflected in R$ 5.19 billion in net financial expenses over the same period. Keep reading below to see exactly how their key resources, like vast iron ore reserves and owned logistics, are structured to manage this high-stakes, integrated operation.

Companhia Siderúrgica Nacional (SID) - Canvas Business Model: Key Partnerships

You're looking at how Companhia Siderúrgica Nacional (SID) builds value through its external and internal alliances, which are critical, especially when the holding company is focused on deleveraging. These relationships are not just about supply; they are about securing core operational needs and driving digital efficiency.

Strategic Digital Transformation with Salesforce for Cement CRM

The digital push in the Cement segment is a clear example of a high-impact partnership. Companhia Siderúrgica Nacional executed a strategic digital transformation using Salesforce solutions, specifically Sales Cloud and Service Cloud, to overhaul customer interaction for its cement business.

This move was about getting a 360º view of each customer. The result is that Companhia Siderúrgica Nacional moved from having zero sales via digital channels a few years ago to achieving 40% of its Cement sales through these new digital routes as of late 2025. Furthermore, the efficiency gain is concrete: teams can now create customer orders in less than two minutes.

Equity Participation and Restructuring in MRS Logística

Rail transport is a lifeline for Companhia Siderúrgica Nacional's mining output. The company maintains a significant, though evolving, partnership through its equity stake in MRS Logística. While the prompt mentions 37.2%, recent disclosures show Companhia Siderúrgica Nacional is actively negotiating the sale of its direct stake, about 19%, to its subsidiary, CSN Mineração, which holds a similar participation, effectively consolidating the group's logistics assets. This internal transaction is valued at approximately R$ 3.26 billion.

MRS Logística operates the 'Corredor Sudeste,' a vital network spanning 1,700 km of track, connecting Minas Gerais production areas to the Itaguaí port. This partnership is essential for the 105 million tonnes annual iron ore production capacity of CSN Mineração.

Exploring Infrastructure Partnerships to Reduce Debt and Strengthen Financials

A primary driver for many current partnership activities is the need to strengthen the balance sheet. As of the third quarter of 2025, Companhia Siderúrgica Nacional's net debt stood at approximately R$ 37.5 billion, with a leverage ratio of 3.14 times the EBITDA. The company's stated goal is to bring this leverage below 3 times by the end of 2025.

The exploration of infrastructure partnerships is formalized through the creation of the CSN Infraestrutura holding. This new entity will consolidate seven assets, including MRS Logística, ports, and highways, serving as a vehicle for partial monetization. The expectation is that this structure will inject 'some billions of reais' in liquidity, potentially pushing the group's leverage below 2.5 times in 2026, without selling core mining or cement operations.

• Fitch Ratings, as of August 2025, expected total leverage to decline to 5.3x and net leverage to 3.3x in 2025 from 6.0x and 3.5x in 2024.
• The company is also seeking a strategic partner for its energy assets, aiming to sell a stake without losing control.

Total Borrowings and Financing	R$ 52.15 billion	9M 2025
Consolidated CAPEX Projection Range	R$ 6.0 to R$ 7.0 billion	2025-2028
Investment Cash Outflows	R$ 4.62 billion	9M 2025
Net Cash from Operating Activities	Outflow of R$ 1.01 billion	9M 2025

Costs of Goods Sold (COGS) for the mining segment are heavily influenced by raw material sourcing. Companhia Siderúrgica Nacional projects its production volume and purchases of third-party iron ore for 2025 to be 42 Mton. To manage the cost of this input, the company projects its Mining C1 Cost (a measure of direct cash cost) for 2025 to be between US$21.5/ton and US$23.0/ton. The C1 cost for 1Q25 was reported at a more efficient $21/t.

When you look at operational inputs, labor and energy costs are always material for a company this size. While Companhia Siderúrgica Nacional benefits from some self-sufficiency, particularly in energy, external factors still pose risks. For instance, the availability and price of raw materials and increased fuel prices are explicitly listed as factors that could cause actual results to differ substantially from expectations. Energy costs, in general, remain a challenge for energy-intensive sectors like metals globally.

You should keep an eye on these key cost components:

• Debt Servicing: Driven by the R$ 52.15 billion in borrowings.
• Capital Deployment: The multi-year R$ 6.0 to R$ 7.0 billion CAPEX plan.
• Raw Material Cost: Managing the C1 cost, aiming for the US$21.5-23.0/ton target for 2025.

Revenue from the Mining segment, which involves the sale of Iron Ore to global steel producers, is clearly a powerhouse. In Q3 2025, the segment shipped over 12 million tons. Specifically, iron ore exports saw a 5.9 percent increase, reaching 11.419 million mt in that quarter.

Companhia Siderúrgica Nacional (SID) is also a significant player in the construction materials space. CSN Cimentos is recognized as the second-largest cement producer in Brazil, following its acquisition of LafargeHolcim (Brasil) assets in 2022. The cement division posted its second-highest sales volume in company history in Q3 2025 at 3,623 thousand tons.

Finally, revenue from Logistics services is derived from railway and port operations. For the second quarter of 2025, the railway logistics arm brought in a Net Revenue of R$ 800.5 million, while the Multimodal Logistics segment reported a Net Revenue of R$ 319.0 million in the same period.
