SXC

SunCoke is a good fish in a structurally shrinking pond. US blast-furnace coke consumption has fallen more than 75% since 1980 (EIA). Within that contracting pond, SXC is the sole significant independent merchant cokemaker, protected by take-or-pay contracts and capital-intensive logistics infrastructure competitors cannot easily replicate. The Phoenix Global acquisition is the most credible structural hedge in the company's history — mill services to EAF operators means revenue regardless of ironmaking route. But 60% of guided 2026 EBITDA still comes from blast-furnace coke, leaving the company fundamentally exposed to the speed and shape of the BF-to-EAF transition.

Snapshot

What it does

SunCoke Energy is the largest independent merchant cokemaker in the Americas. It converts metallurgical coal into blast-furnace-grade coke — the carbon reductant that integrated steel mills cannot replace in the blast furnace process — and sells it under long-term take-or-pay contracts. Its two cokemaking complexes (Haverhill II in Ohio and Granite City in Illinois) supply Cleveland-Cliffs and U.S. Steel respectively. A logistics segment operates inland river and Great Lakes terminals (CMT, Lake Terminal, KRT) with combined throughput capacity exceeding 40 million tons per year. In August 2025, SunCoke completed the $325M acquisition of Phoenix Global, adding an Industrial Services segment that provides scarfing, grinding, and roll-shop support to electric-arc-furnace steel mills globally — a deliberate hedge against long-run blast-furnace demand decline.

The core operating model: SunCoke owns and operates the cokemaking ovens; customers supply the metallurgical coal (or SXC buys it at cost and passes it through); take-or-pay contracts mean the customer pays a minimum fee whether the furnace runs or not. This structure insulates SXC from commodity price swings and short-cycle steel demand volatility, at the cost of customer concentration.

What it is planning

The near-term operational priorities are: (1) restore the Middletown turbine (failure caused ~$10M negative impact in Q1 2026, restart guided late Q2 2026); (2) integrate Phoenix Global and capture $5-10M in annual cost synergies; (3) reduce gross debt from $685.5M to approximately $565-585M by year-end 2026, targeting 2.45x gross leverage; (4) resolve the Granite City contract question with U.S. Steel/Nippon before December 31, 2026.

Strategically, SXC has framed the Phoenix acquisition as the platform for an Industrial Services growth leg: EAF mill services grow as EAF capacity grows, providing an offset to the long-run shrinkage of the blast-furnace coke book. The company has not articulated a path to further acquisitions until leverage is reduced. No active share repurchase program exists as of Q1 2026 filings; the dividend ($0.12/quarter, paid for 27 consecutive quarters per company disclosures) is the primary capital return mechanism.

Catalysts & demand drivers

Near-term (within 12 months):

1. Granite City contract decision (H2 2026): The most binary catalyst SXC faces. The Granite City agreement (~590,000 tons/yr) expires December 31, 2026, extended one year only. Nippon Steel's strategic plans for US integrated steelmaking are publicly undisclosed. Renewal = relief rally and re-rating toward fair value. Non-renewal = impairment wave and another GAAP loss year, repeating the Algoma/Haverhill I playbook.

2. Middletown turbine recovery (late Q2 2026): Management guided turbine restart late Q2, with coke production makeup through H2 2026. A clean restart enables the Q3 2026 EBITDA step-up and validates the $230-250M full-year guidance range.

3. Phoenix synergy capture: $5-10M/yr cost improvements guided for 2026. The sub-3% return on the $325M purchase price from synergies alone is thin, but the strategic EAF hedge rationale is the primary value, not synergy arbitrage.

4. Leverage to 2.45x: Gross debt paydown trajectory is the credit-overhang catalyst. If year-end 2026 debt comes in at target, buyback optionality opens in 2027.

5. Algoma arbitration: Unscheduled free option — any cash recovery from the Haverhill I breach is unmodeled upside.

Structural (multi-year):

• BF reline decisions at Cleveland-Cliffs Burns Harbor (2027) and U.S. Steel Gary Works (2026) signal 15-20 year BF operating commitments by SXC's customers.
• Green-steel/DRI-EAF transition deceleration following Trump DOE hydrogen-hub funding cancellations (October 2025) extends the runway for blast-furnace coke demand.
• Phoenix Global EAF mill services grow with EAF capacity, partially decoupling SXC's revenue from blast-furnace volumes over a 3-5 year horizon.

Track record

Revenue (confirmed from SEC EDGAR XBRL fact sheet):

All figures confirmed from SEC EDGAR XBRL fact sheet.

Key observations:

• Operating cash flow has been positive every single year from FY2009 through FY2025 (lowest: $101.3M in FY2011). The 2025 GAAP loss was non-cash impairment driven.
• Net income has been negative in 4 of the last 12 years (FY2014: -$126.1M, FY2015: -$22.0M, FY2019: -$152.3M, FY2025: -$44.2M) — each driven by large non-cash impairments. In each case, OCF remained robustly positive.
• OCF has fallen sharply: $249M (FY2023) → $169M (FY2024) → $109M (FY2025) — a 56% three-year decline, reflecting the Haverhill I closure and partial-year Phoenix disruption.
• Revenue has peaked: $2.063B (FY2023) to $1.837B (FY2025) — a decline of approximately $226M in two years, consistent with the structural decline in US blast-furnace coke demand.

Balance sheet:

• Gross debt: $685.5M at December 31, 2025 (confirmed from research, consistent with Phoenix acquisition financing)
• Cash: $88.7M at December 31, 2025 (confirmed from fact sheet)
• Net debt: approximately $597M
• Gross leverage: ~3.1x on FY2025 EBITDA of approximately $219M (proxy from research)

Share count: The EDGAR XBRL fact sheet records 69,434,769 shares (tagged 2014-09-30 — a stale basic share count). The implied market cap at $9.61 ($797.6M) reconciles to approximately 83M shares. This discrepancy is an EDGAR XBRL data-staleness artifact; analysts and company disclosures use approximately 83M diluted shares. The annual dividend outflow (at $0.12/quarter) is therefore approximately $39.8M/yr on ~83M shares (not $33.3M/yr on the stale 69.4M XBRL count).

Valuation

Current multiple:

• EV (gross debt basis): $685.5M + $797.6M = ~$1.483B
• EV (net debt basis): $596.8M + $797.6M = ~$1.394B
• 2026 EBITDA guidance: $230-250M (midpoint $240M)
• EV/EBITDA (gross): ~6.2x; EV/EBITDA (net): ~5.8x

Note: The bull case cited a 3.2-3.5x gross-debt EV/EBITDA. The verifier flagged this as methodologically inconsistent (it adds gross debt and market cap, but the EBITDA figure includes the cash-generating assets the cash funds). On net-debt EV, the multiple is ~5.8x — within the bull's own stated peer range of 5-6x for take-or-pay industrials in a neutral credit environment. The stock is fairly valued, not deeply discounted, at the EBITDA guidance midpoint.

Fair value range:

• Base case (Granite City renews, leverage normalizes, Phoenix integrates cleanly): Applying 5-6x EV/EBITDA to $240M on ~$570M net debt (post-paydown) and ~83M shares: equity value of $12-14/share. Consistent with Benchmark's $13 price target (November 2024).
• Bear case (Granite City non-renewal, another $80-100M impairment wave, EBITDA resets to ~$150M): At 5x EV/EBITDA on $150M and ~$640M net debt, equity value approaches $5-6/share.
• Method: EV/EBITDA peer multiple applied to guided 2026 EBITDA, adjusted for net debt at assumed year-end 2026 leverage, divided by ~83M diluted shares.

Ownership & insiders

Institutional ownership dominates; no meaningful insider buying or selling data surfaced in the research. No active share repurchase program is in place as of Q1 2026. The $0.12/quarter dividend ($0.48 annualized) has been paid for 27 consecutive quarters and yields approximately 5.0% at $9.61. With gross leverage above 3x, management has explicitly prioritized debt reduction over buybacks. If leverage reaches 2.45x by year-end 2026 as guided, capital return optionality reopens in 2027. Short interest stood at approximately 7.1% of float in February 2026 (a 21% increase), reflecting institutional bearishness on the Granite City uncertainty and post-acquisition leverage.

Only 2 analysts actively cover SXC: Benchmark (Buy, $13 PT, November 2024) and B. Riley (Neutral, $9 PT, February 2026). Thin coverage means news-flow events — particularly the Granite City decision — will have outsized price impact in a thinly traded stock.

Bull case

SunCoke's operating cash flow has never turned negative in 17 years of reported history — including through steel cycles, customer bankruptcies, and large GAAP impairments. The take-or-pay contract structure and coal cost pass-through model are genuine structural protections, not accounting constructs. The 2025 net loss of -$44.2M and operating loss of -$44.4M are almost entirely driven by two non-cash items: a $90.3M Haverhill I impairment (Algoma Steel contract breach) and Phoenix acquisition restructuring charges. OCF of $109.1M in 2025 shows the underlying cash engine was largely intact.

The Phoenix acquisition is the most strategically important move SXC has made in years. The $90-100M EBITDA/yr Industrial Services segment (2026 guidance) serves EAF mills — exactly the segment that displaces blast-furnace demand long-term. SXC is building a business that earns revenue regardless of ironmaking route, not just managing a declining coal-to-coke franchise.

Blast-furnace reline decisions at Cleveland-Cliffs Burns Harbor (2027) and U.S. Steel Gary Works ($350M reline, 2026) are the most tangible evidence that BF demand does not cliff-edge near-term. Steelmakers do not invest hundreds of millions in furnace relines unless they intend to operate those furnaces for 15-20 more years.

The sequencing that matters: turbine restoration is the first confirming signal (Q2 earnings, late July/early August 2026); Granite City announcement is the make-or-break (Q3-Q4 2026). If both resolve favorably, the path to $12-14 within 12 months is straightforward without requiring a macro steel cycle upturn or met-coal price tailwind.

The dividend (5.0% yield, 27 consecutive quarters paid, backed by never-negative OCF) provides a real yield floor while waiting for the Granite City binary to resolve.

Bear case & red flags

Red flag 1 — Granite City contract cliff (HIGH severity): The U.S. Steel Granite City contract (~590,000 tons/yr, ~17% of 2026 guided volume) was extended for only one year through December 31, 2026. U.S. Steel is now a Nippon Steel subsidiary. No public statement from Nippon commits to renewing or maintaining blast-furnace operations at Granite City beyond 2026. The one-year roll — versus the three-year extension Cleveland-Cliffs received at the same time — is itself a signal that both parties are preserving optionality. The Algoma/Haverhill I precedent is the playbook for non-renewal: $90.3M impairment, permanent capacity closure, multi-year arbitration for a partial cash recovery. Granite City is larger than Haverhill I. B. Riley downgraded SXC to Neutral ($9 PT) in February 2026 citing this uncertainty; short interest rose 21% in February 2026 to ~7.1% of float.

Red flag 2 — Customer concentration (HIGH severity): Cleveland-Cliffs and U.S. Steel/Nippon account for effectively all Domestic Coke segment revenue. There is no deep US spot coke market to absorb displaced volumes if either customer cuts off-take. The Algoma breach proved the model breaks when customers exit. Revenue has fallen from $2.063B (FY2023) to $1.837B (FY2025), a trajectory consistent with volume erosion.

Red flag 3 — Leverage post-Phoenix (HIGH severity): Gross debt of $685.5M at December 31, 2025 (confirmed from fact sheet cash of $88.7M; net debt ~$597M). OCF declined from $249M (FY2023) to $109M (FY2025) — a three-year 56% decline. The management target of 2.45x gross leverage by year-end 2026 is aggressive: bear-case arithmetic (EBITDA $230M, capex $100M, interest ~$41-48M on $685.5M at estimated 6-7%, dividend ~$40M on ~83M diluted shares) implies only $40-55M of organic FCF available for debt reduction, well short of the $100-120M needed to reach target. The gap must be covered by working-capital release or Algoma arbitration proceeds — neither is certain.

Red flag 4 — GAAP net losses episodic but repeating (MEDIUM severity): Net losses in FY2014 (-$126.1M), FY2015 (-$22.0M), FY2019 (-$152.3M), FY2025 (-$44.2M) — all confirmed from fact sheet. Each was impairment-driven, not cash-burning. But the pattern confirms that each major customer disruption produces a GAAP loss year, and a second disruption (Granite City) is approaching.

Red flag 5 — Phoenix integration risk (MEDIUM severity): $325M paid for $5-10M/yr in cost synergies (sub-3% return on purchase price from synergies alone). Q1 2026 showed Phoenix performing to expectations, but it is only the second partial quarter of ownership. Integration of a global services business into a manufacturing culture carries execution risk. If integration stumbles, SXC simultaneously loses its EAF hedge and carries the acquisition debt.

Red flag 6 — Valuation nuance (MEDIUM severity): The "cheap" 3.2-3.5x EV/EBITDA framing uses gross-debt EV. On net-debt EV (~$1.39B), the multiple on $240M EBITDA guidance is approximately 5.8x — within the bull's own stated peer fair-value range. The stock is not as deeply discounted as headline EV/EBITDA framing implies.

Red flag 7 — EIA secular decline (MEDIUM severity): US coke production and consumption have fallen more than 75% since 1980. SXC's weighted-average remaining contract life of ~7 years is a runway, not a moat. Revenue confirms the trend: $2.063B (FY2023), then $1.935B (FY2024), then $1.837B (FY2025). The Phoenix acquisition partially offsets but does not reverse the structural decline.

Interesting findings

• OCF-never-negative is the real story: In each of the four years with large GAAP net losses (FY2014, FY2015, FY2019, FY2025), operating cash flow was positive and substantial ($112M, $141M, $182M, $109M respectively). The take-or-pay + cost-pass-through model is genuinely structural, not cyclical luck.

• The one-year vs. three-year contract extension asymmetry: Cleveland-Cliffs received a three-year Haverhill II extension (November 2025, 500K tons/yr through December 2028). U.S. Steel received a one-year Granite City extension (January 2026). This structural difference in contract terms is the clearest publicly available signal of relative relationship certainty between SXC's two customers.

• Dividend math is tighter than it appears: At approximately 83M diluted shares (implied by market cap), the annual dividend outflow is ~$39.8M — not the $33.3M implied by the stale 69.4M XBRL share count. In a year like 2025 where OCF was $109M and capex guidance is $90-100M, FCF before debt service covers the dividend but leaves thin margin.

• Algoma arbitration as unpriced option: The market appears to be pricing zero recovery from the Algoma breach. Even a partial cash award ($20-30M) would be approximately 2.5-3.8% of market cap with no analyst model crediting it. It is not large enough to change the thesis but is genuinely unmodeled upside.

• Thin analyst coverage amplifies binary events: With only 2 covering analysts, the Granite City contract announcement — whenever it comes in H2 2026 — will drive disproportionate price movement in a thinly traded stock. The setup rewards investors who are positioned before the announcement rather than after.

The read

SunCoke is a genuinely cash-generative industrial business at a genuinely cheap absolute multiple, attached to a structurally declining industry, with a binary contract decision arriving before year-end that will either confirm or destroy the bull case. The Phoenix acquisition is the right strategic move and is the first credible evidence that management sees the secular problem clearly. The leverage incurred to make that acquisition is the constraint that limits defensive flexibility.

The honest characterization is: this is a situation where the base case (Granite City renews, turbine restores, leverage falls) is probably more likely than not — blast-furnace reline investments at both major customers support near-term demand, and no coke supply alternative exists at Granite City's scale. But the consequence of being wrong (non-renewal, another impairment wave, leverage path disrupted) is severe enough, and the one-year contract structure unusual enough, that the risk-adjusted picture is mixed rather than compelling.

The rating of 5.5/10 (Mixed) reflects that duality: real cash generation and real cheapness on one side; real customer concentration risk, elevated leverage, and a binary contract event on the other.
