Gas Ban (ISIN ARGASB010027) was last at ARS 1,610.00 on the Buenos Aires market on October 5, 2026, up 2.55 percent from the previous close. The immediate company catalyst is Argentina's new gas tariff schedule, which took effect on October 1 and includes Naturgy BAN.

October tariffs change the framework

According to Indicadores on October 1, 2026, Argentina's gas regulator approved updated tariff tables for Naturgy BAN and other distributors. The measure applies a 50 percent general discount to base consumption under the targeted subsidy program and an additional 24.25 percent discount for eligible customers.

The tariff decision also introduces a new monthly charge under the 2025-2030 five-year tariff review. For Gas Ban, the key investment question is whether the revised framework improves cash generation after inflation and currency effects, rather than simply lifting headline customer bills.

Revenue reached ARS 811 billion

Fair Value Calculator reports that Naturgy BAN revenue rose from ARS 38.7 billion in fiscal year 2021 to ARS 811 billion in fiscal year 2025. The same source puts fiscal 2025 net income at ARS 183 billion, giving the tariff framework a larger earnings base than the company had four years earlier.

The comparison is substantial but needs context: the figures span years of severe Argentine inflation, so nominal revenue growth does not measure the same economic gain as volume growth. The company operates in natural gas distribution and serves 30 municipalities in the northern and western metropolitan area of Buenos Aires, according to the Naturgy Argentina website.

Valuation remains close to the market price

A September 30, 2026 model from Fair Value Calculator placed the share at ARS 1,605.00 and its modeled fair value at ARS 1,706.00. The model value lies 6.29 percent above ARS 1,605.00, while the source describes the stock as fairly valued and cautions that its data base is limited.

The market capitalization was ARS 609.0 billion on September 30, 2026. That value and the October 5 price place Gas Ban in the small-cap utility segment, where tariff decisions can materially affect the relationship between reported profit, cash flow and investor valuation.
