SGL Carbon's 1H Profit Looked Cleaner - But Is This a Real Turnaround Or Just a Smaller Business?

SGL Carbon's half-year improvement came with smaller sales

SGL Carbon's first-half results improved versus a year ago, but the business also shrank. Sales fell 13.0% to €394.2 million, while net income turned positive at €11.8 million after a €31.4 million loss a year earlier. That is a genuine improvement on paper, but it is not enough on its own to confirm a full turnaround.

Profit mix improved, but demand is still the real test

The cleaner profit profile is credible. Adjusted EBITDA margin improved to 17.7% from 16.0%, and management said part of the sales drop reflected the exit of unprofitable business activities, including loss-making acrylic fiber and precursor production. Removing a weak operation can reasonably improve margins.

What investors still need to see is whether the remaining business is getting healthier, not just whether the reported base is smaller. Management also pointed to lower demand in Graphite Solutions and a challenging order situation in Process Technology, which keeps the outlook uneven.

Restructuring helped, but semiconductor pressure still matters

The more useful question is whether SGL improved the underlying operating mix or simply made the income statement neater by cutting the messier parts.

The restructuring case is visible

After the mid-2025 restructuring, Carbon Fibers/FC adjusted EBITDA improved from €1.5 million to €9.0 million in Q1. That is a more concrete sign of operating change than the headline profit figure alone. SGL stopped loss-making acrylic fiber and precursor production, and also ended sales activities for those products. In that context, an improvement in the remaining business is exactly what you would expect.

Contract adjustments helped earnings, but they were not purely cosmetic

The half-year also included compensation payments of €28.7 million linked to contract adjustments with semiconductor customers. According to the company, those payments related to contractual purchase obligations, and the CEO said high inventory levels at semiconductor customers were still weighing on demand. That points to a real commercial problem being negotiated, rather than a purely accounting-driven relief event.

Why the outlook still looks like a waiting game

Management has reaffirmed its 2026 targets, which gives the recovery case some support. But the backdrop is still cautious. Last year, sales fell 17.2% to €850 million. This year, management confirmed €720 million to €770 million in sales and €110 million to €130 million in adjusted EBITDA. That is more constructive than the prior-year decline, but it does not by itself signal a strong upcycle.

SGL Carbon looks more like a watchlist name than a clean buy

At roughly €4.00, SGL Carbon does not look obviously cheap. The stock's last trading day showed a low of €3.95 and a high of €4.05, the technical score was -2.22, and the site flagged a sell signal from the previous day. For now, the chart looks more like a waiting game than a decisive entry.

The next scheduled checkpoint is 05. November 2026, when SGL is set to issue its statement on the first nine months of 2026. The reason is straightforward: investors have already seen a half-year in which adjusted EBITDA margin improved to 17.7% even as sales fell 13.0%. The next update needs to show more stable demand and less reliance on a smaller, restructured base.

What would improve the investment case

• Sales stop shrinking at the same pace as the prior year.
• Process Technology and Graphite Solutions stop being the clearest pressure points.
• Earnings remain supported after the effect of the semiconductor contract adjustments fades.
• The stock either improves technically or the fundamentals improve enough to make today's price look reasonable.

For now, the cleaner results are real, but the evidence still points to a business in repair mode rather than a fully confirmed turnaround.
