Alpha Trading acquires Trieste fuel terminal, plans €20 million upgrade

Alpha Trading has acquired full ownership of Seastock, the company holding the concession to operate Italy’s Trieste Coastal Storage Terminal, from Tosto Group. Announced on 10 November 2026, the transaction strengthens the marine fuel supplier’s control over storage infrastructure supporting its Mediterranean bunkering business.

The acquisition will be followed by approximately €20 million of investment over the next five to 10 years to improve terminal efficiency and develop infrastructure. The programme supports Alpha Trading’s strategy to expand physical supply of conventional and sustainable energy products at key ports.

The purchase price has not been disclosed. The €20 million figure refers to planned investment in the terminal, rather than the consideration paid for Seastock.

What infrastructure does the acquisition include?

Seastock’s published specifications list 26 storage tanks with a combined capacity of 130,000 cubic metres. Individual tanks range from 130 to 12,000 cubic metres, providing facilities for storing different quantities of petroleum products.

The terminal has access by vessel, road and rail, with jetty facilities supporting marine movements. Its services include product blending, additive treatment and colouring, alongside storage and handling.

These capabilities connect the terminal’s tank infrastructure with both maritime supply and inland distribution. Located on the northern Adriatic coast, the facility serves a region linked to markets across central and eastern Europe.

The site occupies more than 60,000 square metres in Trieste’s San Sabba area, adjacent to the SIOT oil pipeline jetties. Its infrastructure includes a tanker jetty, railway connections and road-tanker loading areas.

What will the investment programme target?

Alpha Trading’s Adriano Parodi said the planned expenditure would improve operational efficiency and flexibility while strengthening workplace safety, environmental protection and cybersecurity.

The development programme also envisages adding hydrotreated vegetable oil (HVO) and other biofuels alongside conventional fuels. This would broaden the products handled through the terminal as the company develops its energy logistics business.

Alpha Trading described the transaction as an extension of its relationship with Walter Tosto, with which it has cooperated since 2018. The purchase therefore builds on an established operating relationship at Trieste.

How does Trieste fit into Alpha Trading’s bunkering network?

Alpha Trading has supplied marine fuels since 1985. Its business covers international trading in fuel oil, marine diesel and alternative fuels, alongside domestic biofuel activities.

The company identifies Koper, Monfalcone, Trieste and Genoa as its physical supply locations, with these activities dating from October 2018. Its existing operations combine energy-product storage with blending capabilities and fuel testing through its own analytical laboratories.

Acquiring Seastock adds direct control of the concession-holding storage business to Alpha Trading’s established supply activities. The terminal’s storage and handling functions complement the company’s existing role in delivering marine fuels across its regional network.

Why is Tosto Group selling the business?

Tosto Group said the disposal would allow it to concentrate on manufacturing large equipment for the energy, nuclear, and oil and gas sectors.

The group acquired the Trieste facilities in December 2020. In 2023, Seastock secured an extension of its port concession to 2060 to support a modernisation and expansion programme.

The ownership change places the terminal under a company already active in local bunkering, with the announced investment directed towards upgrading the facility and expanding its fuel-handling capabilities.
