Argentina’s TGS Doubles Profit as Liquids Top Transport

Earnings · Argentina

Transportadora de Gas del Sur’s second‑quarter 2026 profit rose 147% on stronger liquids earnings at its Cerri Complex near Bahía Blanca and a Ps. 60,191 million (US$ 41 million) improvement in financial results.

Q2 2026 headline results: profit up 147%, revenue up 15%

TGS closed the second quarter of 2026 with comprehensive income of Ps. 133,145 million (US$ 90 million), against Ps. 53,780 million (US$ 36 million) a year earlier, a rise of 147%. The company reports in constant Argentine pesos as of 30 June 2026 under the inflation-accounting standard IAS 29, so that comparison is already adjusted for inflation.

Every peso figure in this article is converted at Ps. 1,484 to US$ 1, the peso’s close on 30 June 2026, the date to which the accounts are restated. On that basis the quarter’s profit is about US$ 90 million, against US$ 36 million a year earlier.

Total revenues for the quarter rose to Ps. 535,522 million (US$ 361 million) from Ps. 464,147 million (US$ 313 million) in the second quarter of 2025, an increase of 15%. Operating profit grew 32% to Ps. 216,327 million (US$ 146 million).

Operations were not the larger part of the story. Operating profit rose by Ps. 52,661 million (US$ 35 million) year on year, while the financial result improved by more: a loss of Ps. 79,313 million (US$ 53 million) narrowed to a loss of Ps. 19,122 million (US$ 13 million), a swing of Ps. 60,191 million (US$ 41 million). TGS attributes that swing mainly to Ps. 130,125 million (US$ 88 million) of higher gains on financial assets and financial instruments. The financial line therefore contributed more to the rise in profit than the operating business did.

Against the backdrop of Argentina’s still‑fragile macroeconomy, this kind of earnings expansion is more than a statistic: it signals that parts of the energy chain tied to global prices and export flows are starting to outweigh the drag from regulated domestic transport, a shift foreign investors have been waiting on for years.

Regulated gas transport vs. the liquids business

Historically, TGS’s core has been its regulated natural gas transportation network, moving molecules from Patagonia and the Neuquén basin to Argentina’s main demand centres under long‑term firm contracts.

In the second quarter the liquids business billed Ps. 238,904 million (US$ 161 million), about 45% of group revenue, while regulated gas transportation supplied roughly 36%. A year earlier the split was 35% liquids against 43% transport.

In the first quarter of 2026 the two segments were level at about 40% of revenue each, on the company’s own figures. The second quarter is therefore the first quarter since 2023 in which liquids has been the larger business — transport had overtaken it after the 2024 tariff increases.

Liquids revenue rose 49%, or Ps. 78,143 million (US$ 53 million). Higher volumes contributed Ps. 84,071 million (US$ 57 million), better international prices Ps. 24,677 million (US$ 17 million) and the weaker peso Ps. 20,244 million (US$ 14 million), offset by Ps. 36,653 million (US$ 25 million) of IAS 29 inflation restatement and Ps. 14,304 million (US$ 10 million) of lower ethane prices, with minor items making up the small remainder. Volumes sold were 56% higher than a year earlier, flattered by a storm that halted production at the Cerri Complex for five weeks in 2025.

Transport revenue fell 4%. A Ps. 48,617 million (US$ 33 million) inflation-restatement charge and lower service volumes outweighed Ps. 50,200 million (US$ 34 million) of tariff increases.

This changing mix matters for the character of Latin American energy: where once the business model hinged on domestic tariffs negotiated in pesos with regulators, the centre of gravity is shifting towards projects and contracts benchmarked in dollars and tied to export markets, with all the volatility and opportunity that implies.

Vaca Muerta midstream: busier, but no richer

Extra gas transport and conditioning work in Vaca Muerta added Ps. 13,197 million (US$ 9 million) to midstream revenue, and the weaker peso a further Ps. 14,815 million (US$ 10 million) on dollar-denominated contracts. Inflation restatement of Ps. 25,340 million (US$ 17 million) cancelled almost all of that, leaving segment revenue up by just Ps. 369 million (US$ 0.2 million).

Operating profit in midstream and telecommunications fell by Ps. 7,352 million (US$ 5 million), mainly on higher taxes and depreciation. The segment slipped to about 19% of group revenue from 22% a year earlier.

Separately, on 12 May 2026 the company won approval to join Argentina’s incentive regime for large investments, known as RIGI, for the expansion of the first section of the Perito Moreno gas pipeline. The NGLs project is a distinct undertaking, and the filing does not report RIGI approval for it.

For investors reading Latin America’s mood, Vaca Muerta increasingly represents not just a geological story but a psychological one: a bet that Argentina can parlay a world‑class shale resource into export revenues resilient enough to outlast political cycles, with midstream operators like TGS acting as the long‑distance translators between local rock and global markets.

US$ 3 billion NGLs megaproject and export ambitions

In its results release of 3 August 2026, TGS said it had reached a final investment decision on its Integrated NGLs Project, at an estimated US$ 3.0 billion. The company expects annual exports of roughly US$ 1.2 billion once it is running from March 2030.

The four‑year build covers a 100km segregation pipeline, an expansion of the Tratayén plant, a multi‑product line to Bahía Blanca, a fractionation plant, storage and a marine loading terminal. That would move TGS decisively into dollar‑earning exports.

In Latin American context, a dollar‑denominated project of this size, in a country still wrestling with capital controls and IMF programmes, signals a quiet confidence: that engineering timelines, regulatory incentives and global demand for NGLs can stay more stable than the headlines, and that midstream infrastructure can become a kind of psychological hedge against domestic macro swings.

For foreign investors, the 2030 start‑up date acts like a horizon line: far enough out to require patience, close enough to start shaping expectations for Argentina’s role in continental gas and liquids flows, with TGS positioned as one of the key gatekeepers.

Credit ratings, regulatory backdrop and balance sheet

S&P Global Ratings raised TGS’s long‑term local and foreign currency debt ratings to ‘B’ from ‘B-’ on 11 June 2026, and Moody’s lifted its notes rating to ‘B1’ from ‘B2’ on 23 July 2026. The company says the upgrades reflect a more favourable view of its credit profile and support its investment plans.

The balance sheet has moved the other way as spending accelerates. Net debt stood at Ps. 497,604 million (US$ 335 million) at 30 June 2026, against Ps. 120,098 million (US$ 81 million) at the end of 2025.

These upgrades lower the psychological and financial hurdles for long‑term funding: for an Argentine issuer, each notch upward translates into broader access to global capital pools and a slightly cheaper cost of debt, particularly important when planning a multi‑billion‑dollar build‑out tied to Vaca Muerta.

Regulated natural gas transportation remains subject to Argentine oversight, with revenues influenced by tariff reviews that historically have lagged inflation and currency depreciation, while non‑regulated segments enjoy more flexibility to price services based on market conditions and, in some cases, export‑linked references.

This dual reality—regulated pipes in pesos, growing liquids and midstream in dollars—feeds into a wider Latin American pattern where infrastructure firms straddle domestic social obligations and global market logic, forcing investors to weigh political risk against the appeal of energy‑export optionality.

How Q2 2026 reshapes TGS’s investor narrative

With comprehensive income up 147% and liquids overtaking transport as the biggest revenue line in Q2 2026, TGS’s story for foreign capital is shifting from a regulated pipeline utility to a hybrid liquids‑and‑midstream platform anchored in Vaca Muerta.

Quarterly data underscore that group growth is no longer coming primarily from tariff updates but from higher NGL production and sales, a pattern investors have seen before in North American basins and are now watching in southern Latin America.

At the same time, the NGLs project, the ratings upgrades and RIGI backing for the Perito Moreno pipeline suggest a state‑supported push to turn Vaca Muerta into a regional export engine, even as domestic politics and macro conditions remain volatile.

For readers of The Rio Times, the feel of this moment is one of cautious acceleration: numbers that finally match the geological promise, a business mix tilting towards global exposure, and an Argentina that, through TGS and its peers, is trying to write itself into the next chapter of Latin American energy trade rather than just surviving the current one.
