Thematic Exposure -- 4/10

Peabody is a diversified coal producer with four reportable mining segments split roughly evenly across US thermal (~48% of revenue) and seaborne/export coal (~50%). It is a meaningful operator in every market it serves, but the #1 player in only one -- the structurally declining US Powder River Basin -- and a low-single-digit-share, price-taking participant in the growing seaborne metallurgical theme. The August 2025 termination of the $3.8B Anglo American met-coal acquisition removed the one event that would have vaulted it into the global met top tier. Passes the oligopoly gate on PRB leadership, but that leadership sits in the wrong (shrinking) market. Weight: 35%
Powder River Basin -- Dominant, but a Declining Theme
Leader of a Shrinking Market
Genuinely durable only in the PRB, where North Antelope Rochelle is the lowest-cost, largest US mine and the basin is a 2-player oligopoly with Core Natural Resources (~66% combined). But being the leader of a declining theme is not the "leaders stay leaders in growing markets" setup the principles reward. US coal production is forecast to fall 512M → 483M → 467M short tons (2024 → 2026E); EIA sees -8% US thermal coal power burn in 2026.
Seaborne Metallurgical -- Growing Theme, but a ~3% Price-Taker
Low-Single-Digit Global Share
The only growing theme Peabody touches is seaborne met (2026 guide 9.3-10.3M tons vs ~320-340Mt seaborne coking trade = ~3% share). It is a price-taker off published indices, competing against BHP/BMA, Teck, Anglo American, Glencore, and Whitehaven -- all larger. Centurion adds premium hard coking coal but does not change Peabody's single-digit global met share.
Anglo Deal Collapse -- Repositioning Catalyst Gone
August 2025 Termination
Peabody terminated the $3.8B Anglo American met acquisition after the Moranbah North CO/ignition incident. The thesis that BTU would become a global met top-3 player is off the table; it remains a mid-tier met producer relying on the organic Centurion ramp.

Segment Revenue Mix (FY2025, Daloopa)

Seaborne Thermal $908.5M 23.6%
Seaborne Metallurgical $1,036.6M 26.9%

Q1'26 reported segment revenue (Daloopa): Seaborne Thermal $197.5M, Seaborne Met $283.0M, PRB $289.5M -- met growing on the Centurion ramp while seaborne thermal declines YoY (Q1'25 ST was $265.1M).

Market Share / TAM / Theme Growth by Segment
Segment % of Rev Market Share TAM Theme Growth
PRB / US Thermal ~48% ~30-35% of PRB alone; Peabody + Core Natural = ~66% of basin. Owns North Antelope Rochelle, world's largest coal mine PRB ≈ half of all US coal; US production 512M (2024) → 483M (2025) → 467M short tons (2026E) Declining. EIA forecasts -8% US thermal coal power burn in 2026 and production cuts through 2027
Seaborne Metallurgical 26.9% ~3% of seaborne met (2026 guide 9.3-10.3M tons vs ~320-340Mt seaborne coking trade) ~$126B global met coal market; seaborne coking trade ~320-340Mt Flat to modest (~3-4% near-term; long-term energy-transition decline per Wood Mac)
Seaborne Thermal 23.6% ~1% of seaborne thermal trade (Australian export ~12-13M tons vs ~1,111Mt global trade) Global seaborne thermal trade ~1,111Mt (down 6% in 2025) Declining (-6% trade in 2025)
Key competitors: PRB -- Core Natural Resources (ex-Arch), Navajo Transitional. Seaborne met -- BHP/BMA, Teck, Anglo American, Glencore, Whitehaven (all larger than Peabody). Seaborne thermal -- Indonesian majors (~30% of trade), Glencore, Whitehaven, Yancoal.

Oligopoly Hard Gate

Peabody share in PRB ~30-35% individually
Any segment >30% share? Yes -- PRB
≤3 players control >70%? Yes -- Peabody + Core Natural ~66%
Gate result PASS (in a declining theme)
4/10 — Peabody clears the oligopoly gate on the strength of its PRB leadership, which keeps it above the fragmented-position floor. But the segment where it dominates is in secular decline, and the only growing theme it touches -- seaborne met -- is one where it holds low-single-digit global share, takes prices off published indices, and competes against five-plus larger producers. The collapse of the Anglo American acquisition (Aug 2025) eliminated the catalyst that would have repositioned BTU within the met theme. A diversified, well-run, but ultimately commodity price-taking coal portfolio with a leadership perch in the wrong (shrinking) market lands in the 3-4 band, not the 7-8 "leader in a growing theme" band.
