Alcoa Corporation

▲ Bull Case

• ◆Structural ex-China supply deficit holds. China at 45 Mt regulatory ceiling with ~95% utilization; ex-China growth limited by greenfield capital intensity ($3–4B/smelter); Russian production sanctions-constrained. Energy-transition demand (EVs, grid, solar) is 3–4% CAGR. LME averages $3,000+/t for 5+ years; AA adj. EBITDA sustains $2.4B+.
• ◆AWAC consolidation is an unappreciated NAV event. 100% ownership of world's most valuable integrated bauxite-to-alumina platform should command 0.5–1.0 EV/EBITDA re-rating versus legacy comparable multiples. At $2.5B adj. EBITDA, that represents ~$9/share of unrecognized value not yet digested by the market.
• ◆Green-aluminum premium is a free option. Hydro-powered smelters (Norway, Canada, Brazil) plus ELYSIS zero-carbon JV with Apple/Rio = only US-listed pure-play. EU CBAM and OEM Scope 3 commitments could expand premium from $50–150/t to $200–300/t—incremental $100–175M EBITDA at 8x multiple = $3–5/share tailwind.

▼ Bear Case

• ◆The cycle is turning and AA is operationally levered to the downside. Every $100/t LME decline = ~$230–250M adj. EBITDA hit. Historical LME mid-cycle is $2,400–2,600/t (vs. current $2,900–3,000); 30-year history includes 2019 ($1,790/t) and 2023 ($2,254/t). A normal cycle turn compresses adj. EBITDA from $2.4B to $1.5–1.9B, EPS from $7.00 to $4.50–5.00, and at 10x P/E the stock is worth $45–50, not $72.
• ◆US tariffs are a borrowed shield, not a structural moat. The 50% tariff is executive action—reversible within 12–24 months by new administration or WTO ruling. Pre-tariff Midwest Premium history is $300–500/t; current $700–1,940/t is the anomaly. Step-down to historical norms = $300–500M EBITDA headwind not reflected in consensus estimates.
• ◆CapEx absorbs FCF; restart 'option' is already in consensus. FY2025 FCF of $567M was only 28% of adj. EBITDA—premium industrials convert at 50%+. Q1 2026 FCF was -$298M (working capital). CapEx stuck at 5% of revenue for 4 years despite 'normalization' promises. San Ciprián and Alumar restarts are already embedded in $7.00 FY2026E consensus EPS—remaining perceived upside is fully priced.

“The Street debate centers not on whether AA is a good business—both sides agree it is a commodity price-taker—but on the durability of the current upcycle and appropriate exit multiple. Bulls (e.g., UBS 2026) treat $3,000/t LME and ~$700/t US Midwest Premium as the new normal and apply 10x P/E to $7+ EPS, yielding $70–95 fair value. Bears apply mid-cycle EPS ($4–5) at 10x multiple, yielding $40–50. The critical unresolved point: most analysts have NOT recalibrated target multiples for the AWAC step-change (100% integrated platform ownership vs. minority-held pre-2024). This recalibration represents the bull thesis edge if it occurs; absent it, the stock compresses toward historical peer multiples.”

• ◆LME aluminum sustained >$3,100/t (35% probability, +10–15% upside)
• ◆San Ciprián full-rate confirmation Q3 2026 (75% probability, +2–4% upside)
• ◆Special dividend or expanded buyback program 2H 2026 (45% probability, +3–8% upside)
• ◆Elliott Investment Management strategic action: asset monetization or accelerated capital return (30% probability, +5–15% upside)
• ◆EU CBAM expansion and OEM green-aluminum contracts (40% probability, +5–10% upside)
• ◆ELYSIS commercial-scale deployment with paying customer (25% probability, +10–20% upside)
• ◆Activist-driven strategic acquisition or leveraged privatization (15% probability, +15–30% upside)

• ◆LME aluminum decline $200/t or more (30% probability 1yr, -$460–500M adj. EBITDA impact)
• ◆Power cost spike +$10/MWh in Europe/Australia (Low–Medium probability, -$300–320M EBITDA)
• ◆US tariff reversal or modification under new administration (15% probability 1yr, -$300–500M EBITDA)
• ◆China lifts 45 Mt regulatory capacity ceiling (Low–Medium probability, -$200–400M via LME compression)
• ◆Indonesian/Middle East new smelter supply absorbs global deficit (Medium probability, LME -$100–300/t pressure)
• ◆Global recession 2027–2028 (20–25% probability, EPS compresses to $2–3 range)
• ◆Guinea political instability or CBG bauxite supply disruption (Medium probability, -3–4 Mt bauxite supply impact)
