Portugal’s Galp Enjoys Third-Quarter Margin Windfall at Sines Refinery

Portugal’s only integrated oil company has just reported a third-quarter figure that caught analysts, investors and even the Government’s energy team off guard: an average refining spread of USD 9.5 per barrel, more than double the level seen a year ago. The jump matters not only to Galp’s balance-sheet but also to tax receipts, electricity tariffs and the Lisbon stock market, making it one of the most consequential data points to emerge this autumn.

A surprise windfall from Sines

The last time the Sines refinery delivered such a rich margin, Brent crude was trading above USD 100 and European demand for diesel was booming. In contrast, this summer Brent hovered in the high-60s. The strong spread therefore reflects primarily the pricing power on refined products, not a spike in feedstock costs. Sines processed roughly 22.7 M barrels between July and September, a 7 % rise versus the previous quarter, after engineers resolved an Iberian grid blackout that had briefly slowed operations in late April. With the plant running near its technical ceiling, every extra cent in the crack spread went straight to operating cash flow.

Why margins took off

Several moving pieces converged to push refining profits skyward:

• Distillate prices: New-York diesel crack spreads touched 85 cents per gallon in July, almost twice last year’s level, in part because shipping disruptions in the Red Sea squeezed Middle-East supply.• Cheaper feedstock: Galp’s trading desk secured heavier, sour crudes at discounts of up to USD 4 a barrel to dated Brent, leveraging the refinery’s high-complexity units that can crack tougher molecules into gasoline and jet fuel.• Exchange rate help: The euro’s slide to 1.05 against the dollar cushioned costs for a Lisbon-based refiner paid in EUR but selling products priced in USD.• No major turnarounds: Unlike the spring of 2024, when scheduled maintenance clipped throughput, the third quarter saw full utilisation of conversion units.

Taken together, those factors yielded the strongest Portuguese refining margin since early-2024’s brief USD 12 peak.

Head-to-head with European rivals

Galp’s USD 9.5/bbl clearly leads the Iberian league. Repsol posted USD 8.8/bbl, while France’s TotalEnergies reported the equivalent of about USD 8.2/bbl after converting its USD 63 per tonne figure. Italian peer Eni will disclose results later this month, but analysts expect a high-7 dollar number. For Portuguese investors this matters because it underscores the competitive edge of Sines’ hydrocracking train, upgraded only six years ago with €285 M in EU co-funding. A narrower gap would have raised questions about the asset’s long-term viability; instead, Galp now enjoys margin leadership on the Atlantic coast.

Implications for Portuguese wallets and portfolios

Higher refinery profits translate into several tangible outcomes at home:

• Treasury intake: Corporate tax on the refining segment alone could reach €80-90 M for Q3, a welcome boost to a budget already pressurised by wildfire-related spending.• Fuel prices: The margin is earned mainly abroad, as 60 % of Sines output sails to northern Europe and the US East Coast, so pump prices in Portugal are unlikely to spike purely because of Sines’ profitability.• PSI-20 weighting: Galp’s shares climbed 6 % on the trading-update day, lifting the index and many domestic pension funds whose top-three holdings include the stock.• Cash flow for renewables: Management reiterated its plan to funnel a third of operating cash flow into solar and green hydrogen projects in Alentejo, meaning the fossil windfall could accelerate Portugal’s clean-energy timeline.

The road ahead: maintenance, diversification and dividends

Investors should not extrapolate USD 9.5 into 2026. A major turnaround at Sines is pencilled in for late-2025, likely trimming throughput by up to 15 %. Moreover, forward curves show European gasoline cracks narrowing toward winter. Even so, Galp has nudged full-year group EBITDA guidance to “above €2.7 B”, from €2.5 B previously, and kept its through-the-cycle dividend policy unchanged—committing roughly one-third of operating cash to shareholders. As long as the company continues to hedge Brent and lock in advantageous crude blends, the refining segment should remain a robust cash generator. That cash, in turn, may finance the very technologies Portugal hopes will dominate its energy mix in the next decade.

In short, the third-quarter refining bonanza gives Galp breathing room to invest, the State additional revenue and local investors a timely boost, even if the party may cool once the Sines heaters go dark for maintenance.
