Will STLD generate over $1.5B in free cash flow in FY2026?

The path to $1.5B FCF requires CFO of ~$2.1B+ with $600M CapEx. FY2025 CFO was $1.4B on $2.2B EBITDA. For CFO to reach $2.1B, EBITDA needs to increase meaningfully (aluminum contribution + stable steel earnings) with manageable working capital. If EBITDA grows to $2.5-2.7B (current $2.2B + $200-300M aluminum + stable steel), CFO could reach $2.0-2.2B. But working capital headwind from aluminum ramp, Q1 profit sharing, and potential HRC pricing weakness create downside risks. The $1.5B threshold is achievable but requires steel earnings to hold and aluminum to contribute more than minimal EBITDA.

The CapEx decline from $948M to $600M is the single largest driver — it directly adds $348M to FCF compared to FY2025. Starting from FY2025 FCF of ~$450M, the CapEx reduction alone brings FCF to ~$800M. To reach $1.5B, CFO needs to increase by $700M. This is achievable if: (1) steel operations maintain $1.4B OI (flat with FY2025), (2) aluminum contributes $200M+ EBITDA, (3) working capital is neutral. The biggest risk is steel margin compression from HRC pricing weakness or economic slowdown, which could offset the CapEx benefit.

Structural analysis: FY2025 EBITDA $2.2B minus CapEx $948M = $1.25B EBITDA-CapEx. With $600M CapEx, same EBITDA yields $1.6B EBITDA-CapEx. But FCF is CFO minus CapEx, not EBITDA minus CapEx. The difference is taxes, interest, and working capital. FY2025: $2.2B EBITDA generated $1.4B CFO (bridge of $800M in taxes, interest, working capital). If the EBITDA-to-CFO bridge stays similar, $2.4B EBITDA (aluminum adds $200M) minus $800M bridge = $1.6B CFO minus $600M CapEx = $1.0B FCF. Hmm — that is below $1.5B. To reach $1.5B FCF: $1.5B + $600M = $2.1B CFO. Need $2.1B/$0.64 conversion ≈ $3.3B EBITDA. That seems too high. Let me reconsider — the bridge may improve with lower interest and lower working capital. Adjusted: ~40-50% probability.

The math is tight. FY2025: $1.4B CFO - $948M CapEx = ~$450M FCF. For FY2026 at $600M CapEx, need $2.1B CFO. That is a 50% increase in CFO year-over-year. The CapEx reduction helps the FCF calculation but does not directly increase CFO. CFO growth requires: (1) higher EBITDA from aluminum contribution, (2) maintained steel earnings, (3) favorable working capital. Aluminum may contribute $100-200M EBITDA in FY2026 (first year, ramp). Steel earnings depend on HRC pricing. Working capital pressure continues from aluminum ramp. A 50% CFO increase in one year is aggressive.

The key insight is that FY2025 CFO of $1.4B was suppressed by aluminum working capital ($155M in Q4 alone) and growth CapEx working capital effects. If working capital normalizes in FY2026 (structural aluminum increase largely captured per CFO), that alone could add $100-200M to CFO. Combined with $100-200M aluminum EBITDA contribution and stable steel earnings, CFO could reach $1.8-2.1B. At $600M CapEx, FCF = $1.2-1.5B. Getting to exactly $1.5B requires the upper bound of each assumption, making it achievable but not the base case.

Three sources of FCF improvement vs FY2025: (1) CapEx reduction: +$348M, (2) aluminum EBITDA contribution: +$100-200M to earnings, (3) working capital normalization: +$0-150M. Total improvement potential: $448M-698M. Starting from $450M FCF, this yields $898M-$1.148B FCF range. To reach $1.5B requires $1.05B improvement — above the upper bound of my estimates. The only path is if aluminum contributes more aggressively ($250M+) AND steel margins improve AND working capital is favorable. This is the tail of the distribution, not the center.

FY2025 FCF ~$450M. CapEx reduction adds $348M. Aluminum EBITDA adds $100-200M. Working capital improvement adds $0-150M. Total improvement: $448-698M. FCF range: $898M-$1.148B. Below $1.5B threshold. Need above-base outcomes on all factors to reach $1.5B.

The FCF inflection is real — CapEx decline is a structural improvement. But $1.5B is an ambitious threshold for FY2026. More realistic FCF range is $800M-$1.2B depending on steel margins and aluminum ramp. The 5-year average FCF of $2.2B (or $3.2B excl. growth CapEx) suggests the long-term potential exists, but FY2026 is a transition year, not the steady state.

Steel FCF inflection will be visible in FY2026 but $1.5B is the upper tail. Central estimate around $900M-$1.1B FCF. CapEx reduction is guaranteed improvement, aluminum contribution is likely but modest, working capital is uncertain. The 5-year averages include peak pricing years that flattering the comparison.
