Summa Group

Ziyavudin Magomedov, the founder and principal, made all major investment and acquisition decisions alongside his brother Magomed. The group operated as a closely held family conglomerate without external investment committee input. Decision-making authority ceased to function after the brothers' arrest in March 2018.

Russian authorities arrested Ziyavudin and Magomed Magomedov in March 2018 on charges of embezzlement and organized criminal activity, alleging they siphoned roughly $45 million from state infrastructure projects. The arrests triggered immediate creditor demands, asset freezes, and the eventual sale or transfer of the group's holdings to other Russian entities.

Summa frequently partnered with state-owned entities and other oligarch-linked structures. The group held joint ventures with Transneft in port infrastructure and co-invested with VTB Bank in grain terminals. Direct co-investment with Western institutional investors was not a documented part of its strategy.

The Commercial Sea Port of Novorossiysk shareholding was transferred to Transneft. Fesco Transportation Group was seized and placed under state management. United Grain Company's stake was sold to VTB Bank. No significant assets currently trade under the Summa Group name.

Summa maintained trading and treasury offices in the Netherlands and Switzerland, primarily for commodity export logistics and financing. The group also invested in a Silicon Valley co-working space and made minority venture bets, but the material balance sheet remained overwhelmingly exposed to Russian hard infrastructure.
