A cash reset fighting gas and chemical risks
- Sasol is in a reset phase under CEO Simon Baloyi, focusing on safety, steadier plants, and cash generation.
- The Secunda destoning plant reduced sinks below 12%, driving production to a five-year high.
- The South African value chain improved its cash breakeven to USD 49 per barrel in FY26.
- Net debt reduced to USD 3.3 billion in FY26, outperforming previous guidance targets.
- The Mozambique gas transition and a structural debt mismatch remain key long-term risks.
Reset first, payoff later
Sasol is trying to become simpler and more reliable before asking investors to believe in growth again. The most important near-term win is at Secunda, where the destoning plant successfully reduced sinks below 12%. Better coal quality helped drive a five-year production high of 7.26 million tonnes at Secunda in FY26.
The bull case is gaining traction. The South African value chain cash breakeven dropped to USD 49 per barrel. While macro tailwinds helped this number, it reflects genuine progress in restoring the value chain. That gives Sasol more room to pay down debt, with FY26 net debt dropping to USD 3.3 billion ahead of schedule.
The harder part is International Chemicals. Weaker chemical markets keep the pressure on. Management opportunistically stepped into Natref capacity following the Prax SA interim business rescue, but the chemical reset remains a watch item.
The bear case is still serious. Sasol has repeated impairments, debt that is mostly in U.S. dollars while much of its earnings are in rand, and a Mozambique gas cliff after 2028. Continued execution on debt and operations is required to fully resolve these issues.
Coal, gas, and price cycles
Sasol makes money by turning coal, natural gas, and other feedstocks into liquid fuels, synthetic fuels, gas, and chemicals. The South African chain is deeply integrated. Mining supplies coal, gas supports the system, and Secunda converts those inputs into fuel and chemical products.
This model can generate cash when plants run well and oil, fuel, and chemical prices are supportive. It can also break quickly. Lower oil prices, weak chemical demand, poor coal quality, refinery downtime, or a weaker rand can all hurt profits.
Management has moved the company into two main operating blocks: Southern Africa Energy and Chemicals, and International Chemicals. The goal is to cut complexity, focus capital, and push each unit to earn its keep.
What Sasol sells
Liquid fuels
Fuels are a core part of the South African business. They are tied to oil prices, refining margins, and Secunda reliability.
Synthetic fuels
Sasol uses its Fischer-Tropsch technology to make fuel from coal and gas. This is a long-running strength, but it carries emissions and impairment risk.
Natural gas
Gas from Mozambique supports Sasol's South African customers and internal value chain. Existing Mozambique resources are running down, with no further extension expected after 2028.
Base chemicals
These include ethane, ethylene, polyethylene, and other building blocks. They are very sensitive to global demand, feedstock costs, and plant uptime.
Specialty and care chemicals
These include surfactants and raw materials used in detergents, personal care, agriculture, and industry. Sasol is trying to lift margins by focusing on value over volume.
Sustainable aviation fuels
Sasol had a joint venture with Topsoe called Zaffra B.V., which is now being operationally wound down as the company refocuses on core assets.
Two big blocks now
The mix uses FY2025 external turnover from the Form 20-F segment review. Southern Africa Energy and Chemicals combines Mining, Gas, Fuels, and Chemicals Africa.
What could go wrong
Chemicals recovery stalls
High impact · Medium oddsInternational Chemicals still faces weak demand and pricing. If the reset does not lift margins, cash generation and asset values remain at risk.
More asset impairments
High impact · High oddsSasol has recorded large write-downs, including ZAR 13 billion in FY25 and further H1 FY26 impairments across Secunda and Mozambique gas. These noncash charges show that some assets may not earn enough under current price assumptions. Repeated impairments hurt investor trust.
Mozambique gas cliff after 2028
High impact · High oddsManagement has stated South Africa will need to move to LNG because there is no possibility of further extensions from existing Mozambican resources past 2028. That transition is complex and expensive. Project returns are also pressured by a high 18% WACC rate in Mozambique.
Debt currency mismatch
High impact · Medium oddsMore than 90% of debt is in U.S. dollars, while much of Sasol's earnings are rand-based. A weaker rand can make debt harder to manage. Management is issuing local bonds to reduce the mismatch, but the risk has not gone away.
Policy and tariff pressure
Medium impact · Medium oddsSasol faces long-term emissions rules in South Africa and trade pressure abroad. A 30% U.S. tariff creates an estimated unmitigated risk of USD 60 million for South African chemical exports. These costs could reduce the benefit of the operational reset.
In one breath
What does Sasol actually do?
Sasol turns coal and natural gas into fuels and chemicals. It also sells international chemicals used in plastics, detergents, personal care, and industrial products.
Why is Secunda so important to Sasol?
Secunda is the center of Sasol's South African value chain. When coal quality improves and the plant runs smoothly, Sasol can lower its cash breakeven and generate more cash.
When could Sasol bring back a dividend?
The key hurdle is debt. Net debt was USD 3.3 billion at the end of FY26, and management is working to reach a USD 3.0 billion target before reinstating the dividend.
What is the biggest long-term issue for Sasol?
The Mozambique gas transition is a major challenge. Existing gas extensions are not expected after 2028, so Sasol needs a workable LNG solution.
