You need to see how their Key Activities and Customer Segments are shifting to support this dual focus-it's a blueprint for industrial resilience, so check out the breakdown below.

Steel Dynamics, Inc. (STLD) - Canvas Business Model: Key Partnerships

You're looking at the core relationships that keep Steel Dynamics, Inc. running strong as of late 2025. These aren't just transactional links; they're integrated parts of their circular model.

Internal Metals Recycling operations supply ferrous scrap to mills

Steel Dynamics, Inc.'s OmniSource metals recycling division is the engine feeding its electric arc furnace (EAF) mills. This internal supply chain is critical for maintaining low-carbon production. For the third quarter of 2025, OmniSource reported an operating income of $32 million, which was $10 million higher than the sequential second quarter, driven by near-record ferrous scrap shipments. That's solid performance from the scrap side. To give you a sense of scale, in 2024, the recycling operations shipped 5.85 million gross tons of ferrous metal. Furthermore, Steel Dynamics noted that about 82% of the material used in its steel mills in 2022 was recycled ferrous scrap, showing deep reliance on this internal stream.

The cost of that key input has been relatively stable. For the first nine months of 2025, the average ferrous scrap cost per ton melted at the steel mills was stable at $391 per ton.

Here are some key operational metrics related to this internal partnership:

Completed acquisition of New Process Steel (Dec 2025) for downstream distribution

This was a major move right at the end of the year. Steel Dynamics, Inc. announced the completion of its acquisition of the remaining 55% equity interest in New Process Steel, L.P. on December 1, 2025, taking total ownership to 100%. This followed an initial purchase of a 45% minority interest back in 2022. Honestly, this acquisition deepens a relationship because New Process Steel was already Steel Dynamics, Inc.'s single largest flat roll steel customer. New Process Steel employs approximately 1,275 individuals and operates four manufacturing locations in the U.S. and two in Mexico. The goal here is clearly expanding exposure to higher-margin, value-added manufacturing.

Strategic suppliers for non-ferrous scrap and biocarbon material

The partnership with Aymium is central to Steel Dynamics, Inc.'s decarbonization strategy. They formed a strategic joint venture, SDI Biocarbon Solutions, where Steel Dynamics owns 75% and Aymium owns the remaining 25%. This venture produces renewable biocarbon to replace anthracite in the EAF steelmaking process, targeting Scope 1 GHG emission reductions. The facility, located in Columbus, Mississippi, is expected to have an annual production capacity of 228,000 metric tons. This is a step up from earlier projections, which estimated an initial facility capability of over 160,000 metric tons per year. This onshoring of carbon needs reduces reliance on imported fossil fuels like anthracite coal.

Technology partners for advanced scrap separation capabilities

While the search didn't yield a specific 'scrap separation' technology partner name outside of the recycling platform itself, the Aymium joint venture represents a key technology partnership for advanced material processing-specifically, using high-temperature pyrolysis to convert biomass into high-purity biocarbon. This technology is integral to Steel Dynamics, Inc.'s lower-embodied-carbon product lines, BIOEDGE™ and EDGE™. The facility began commissioning in the first quarter of 2025.

Long-standing customer relationships, often acting as partners

The New Process Steel deal is the prime example here; integrating your largest customer is the ultimate partnership alignment. Beyond that, the launch of BIOEDGE™ and EDGE™ steel products shows a commitment to co-developing solutions with customers to meet their sustainability targets. Steel Dynamics, Inc. anticipates immediate interest from automotive and construction customers for these lower-embodied-carbon offerings. These aren't just sales; they are supply-chain solutions built around long-term customer needs.

Steel Dynamics, Inc. (STLD) - Canvas Business Model: Key Activities

You're looking at the core engine room of Steel Dynamics, Inc. (STLD) as of late 2025, focusing on what they actually do day-to-day to generate revenue and manage costs. It's all about execution across their integrated platforms.

Operating four core segments: Steel, Recycling, Fabrication, and Aluminum is the structural backbone. The third quarter of 2025 showed strong results from this diversification, with consolidated net sales hitting $4.8 billion and Adjusted EBITDA reaching $664 million. The steel segment was the clear driver of operating income for the quarter.

Manufacturing low-carbon-emission steel via Electric Arc Furnaces (EAFs) is central, supported by their recycling platform and new decarbonization efforts. The company achieved a significant milestone by producing its first biocarbon material, which was then successfully consumed at the Columbus Flat Roll Steel Division, directly supporting a lower-carbon supply chain.

Ramping up the new $2.7 billion aluminum flat rolled products mill is a massive ongoing activity. The team successfully produced qualified aluminum flat rolled products for the industrial, beverage can, and automotive sectors during the third quarter of 2025. Management guided that they expect this new operation to be EBITDA positive or better in the fourth quarter of 2025, aiming to exit 2025 operating at approximately 50% capacity. The total capital investment for the mill and supporting satellite centers was authorized around $2.2 billion plus additional costs, with a projected through-cycle annual EBITDA contribution of $650-$700 million.

Managing a highly variable cost structure to maintain margin is a constant focus, especially in the steel segment. This structure, inherent to their minimill operations, allows for rapid adjustment. Here's the quick math on how they managed margin in Q3 2025 steel operations:

• Average Ferrous Scrap Cost fell $27 per ton sequentially.
• Average Realized Steel Selling Price fell only $15 per ton sequentially.
• This resulted in metal spread expansion, driving steel operations operating income up 30 percent sequentially to $498 million.

Finally, executing a $1.5 billion share repurchase program authorized in Q1 2025 demonstrates capital allocation in action. This new authorization, announced in February 2025, was additive to a previous program. In the third quarter alone, Steel Dynamics, Inc. executed share repurchases totaling $210 million, which represented 1.1 percent of its outstanding shares. This activity complements their consistent dividend increases.
