SGL Carbon's Turnaround Gains Traction as Growth Pivot Accelerates
In its first-half 2026 results, SGL Carbon SE (SGL.DE) delivered a crisp message: the painful restructuring of the carbon fiber business is done, and the company is now pivoting toward higher-growth applications. Revenue fell 13% to €394 million, but that decline is almost entirely attributable to the exit from loss-making carbon fiber operations, while EBITDA pre slipped only 3.7% to €70 million, yielding a healthy 17.7% margin. As CFO Thomas Dippold noted, the net result swung to a positive €11.8 million, and free cash flow reached €31.4 million, cutting net financial debt and lifting the equity ratio to nearly 40%.
Half-Year Results: A Cleaner Earnings Base
The scale of the turnaround is best captured by the compensation payment flow. After collecting €7.7 million in Q1 and renegotiating another €21 million in take-or-pay contracts during H1, management confirmed that the largest part of the compensation discussions is now resolved. “Yes, we are currently in negotiation. As I just said, we have reached agreement with two of the contracts. We are, of course, in discussions with others.” — Thomas Dippold, CFO · 2026-08-06 This contrasts sharply with the prior year when the company was still in the thick of talks. In the August 2024 call, the CEO acknowledged losing a major automotive project and expecting a breakup fee, but the process stretched on. Now, the compensation stream has become a tangible bridge to profitability.
Segment-wise, Graphite Solutions reported a 6% sales increase, but that includes the compensation payments; excluding them, revenue slipped 6% on weak industrial demand. Process Tech remained the sore spot: sales plunged 28.2% and its EBITDA pre margin collapsed from 28.3% to 14.5%. Management attributes this to postponed chemical-industry investments and Middle East uncertainty, but they see early signs of order stabilization on a low base. In the Q&A, Dippold clarified that new project awards will only turn into sales in early 2027, so the second half will look similar.
The Growth Pivot: Semiconductors, Nuclear, and Beyond
The most compelling narrative shift is the strategic push under SGL Growth 2030. CEO Andreas Klein highlighted a “positive momentum in the market, especially in China and SiC” — Andreas Klein, CEO · 2026-08-06 — primarily volume but also price stabilization. That dovetails with global tape data showing silicon carbide names as 360-day advancers. SGL is also doubling down on nuclear: “we have announced on Monday that we have reached a new agreement with X-energy to expand our nuclear graphite production capacities.” — Andreas Klein, CEO · 2026-08-06 The company is also progressing in space (rocket-nozzle materials), defense (drone prototypes in sampling and bidding), and aero (doubling production of retrofit floor panels). These are company-specific, high-conviction themes that were not prominent even two quarters ago, when the keyword trajectory was slower to reflect them.
We also kept our promises. … We have accomplished the target. Our overall restructuring costs were a little bit more than EUR 40 million, and we did it in less than one year.
The fiber composites business, now merging carbon fiber and composite solutions, delivered a remarkable margin improvement to 11.5% (ex-BSCCB contribution). This directly validates the restructuring playbook. The prior-year calls were consumed by the Carbon fiber business’s existential question; today, that legacy is no longer a drag.
Watch Items: Compensation and Process Tech
Two risks bear watching. First, the compensation payments are one-time in nature, and CFO Dippold’s guidance on 2027 remains cautious — the full benefit of resurfacing demand will be realized only next year. Second, Process Tech is still in a trough, and the company’s full-year guidance of only a slight decline looks optimistic against the H1 drop. The analyst pressed this point, but management held the line, citing possible catch-up in maintenance and parts. As Dippold put it: “We see the development of Process Tech in the remaining six months of the year on the level where we are right now, maybe a little bit better, but not a magic turnaround story.” — Thomas Dippold, CFO · 2026-08-06 That is a realistic but unspectacular outlook.
With a market cap of roughly €550 million, SGL is a small-cap in the midst of a fundamental transition. The market hasn’t yet re‑rated it — the stock’s price action is unavailable in our dataset — but the fundamentals are inflecting: net result positive, leverage down to 0.6x, and a credible pipeline of growth projects. The company is no longer a restructuring story; it’s a specialty-materials company betting on semiconductors, nuclear, and defense. If even part of the 2030 €1 billion sales target materializes, today’s valuation could look very different.
