LetterOne
LetterOne took shape in 2013 when Alfa Group's founding principals—Mikhail Fridman, Petr Aven, and partners—sold their 50% stake in TNK-BP to state-controlled Rosneft for roughly $28 billion. They carved out $14 billion as the initial capital base for a new, Luxembourg-domiciled holding company designed to invest globally, distinct from the group's legacy Russian banking, telecom, and oil assets. The firm's governance was deliberately westernized from the start: its board includes Lord Davies of Abersoch, the former UK trade minister and Standard Chartered chairman, as a non-executive chairman. The firm operates across three primary verticals. In technology, LetterOne built a large position in the London-listed classifieds-to-venture group Prosus, alongside direct stakes in digital infrastructure. Its energy vertical, L1 Energy, was originally helmed by former BP CEO Lord John Browne and acquired German oil and gas producer DEA, later merging it with Wintershall to create Wintershall Dea. The health arm, L1 Health, targets biotech and care delivery. The firm does not raise third-party funds—all commitments come from the founders' permanent capital base—which allows for patient, concentrated positions. Confirmed exits include the $5 billion sale of DEA's upstream business and a significant stake in Holland & Barrett, the UK health retailer (per Financial Times, 2017). Beyond the Luxembourg headquarters, the firm's investment operations run primarily out of London. The collapse of the Russian regime's relationship with the West following the 2022 invasion of Ukraine forced a radical restructuring. Fridman and Aven were sanctioned by the EU and UK, and LetterOne's core assets, including the Wintershall Dea stake and a share in VEON, the telecoms group, were either written down, seized, or subjected to intense regulatory scrutiny. The firm's current posture is defined by managing what remains—primarily uncorrelated tech holdings and distressed credit opportunities that emerged from the restructuring. LetterOne's structural distinction lies in its origin: a fund born from a single liquidity event that was deliberately built with Western governance from day one, yet remains captive to the geopolitical fate of its founders. It is neither a traditional family office recycling generational wealth nor a conventional private equity firm. The sanctions regime has forced a de facto separation between the founders and the investment committee, creating an unusual, externally mandated governance model where independent directors now steward a multibillion-dollar pool of seized-adjacent capital.

Frequently asked questions
What is the current governance structure of LetterOne following sanctions against its founders?
After Mikhail Fridman and Petr Aven were sanctioned in 2022, both resigned from the LetterOne board. The firm is now governed by an independent board led by Chairman Lord Davies. The founders have no role in investment decisions or operations, and the firm has publicly stated that they do not receive any dividends or economic benefit from the entity.
How does LetterOne source its deals without a traditional LP base?
LetterOne deploys permanent capital from its founding shareholders, which removes the pressure of fundraising cycles or LP redemption risk. The firm's origination relies on a network built by its London investment team and board relationships, particularly in European energy, telecom infrastructure, and US growth equity. Its ability to write large equity checks without leverage constraints historically allowed it to access proprietary situations, though the sanctions regime has compressed its deal-making capacity.
What happened to L1 Energy and its oil and gas holdings?
L1 Energy was the firm's dedicated energy vertical, initially led by former BP CEO Lord John Browne. Its primary asset was a controlling stake in DEA, a German upstream producer, which was later merged with BASF's Wintershall to form Wintershall Dea. Following Russia's 2022 invasion and the subsequent European energy crisis, the Wintershall Dea stake was severely impaired. The group has written down the value of its Russian legacy-linked energy assets and pivoted its focus to renewable and transition-oriented opportunities.
Is LetterOne a Russian entity or subject to sanctions?
LetterOne is domiciled in Luxembourg and is not itself a sanctioned entity. However, its co-founders, Mikhail Fridman and Petr Aven, are individually sanctioned by the EU and UK. As a result, the firm's assets were effectively frozen from the founders' control and placed under independent oversight. LetterOne has legally challenged EU sanctions against its founders, arguing they have no ongoing influence over the firm.
What is LetterOne's affiliation with Alfa Group?
LetterOne was capitalized using proceeds realized by Alfa Group's founders from the sale of their TNK-BP stake. Alfa Group remains a separate entity encompassing the founders' original Russian banking, insurance, telecom, and retail holdings. LetterOne was structured as an internationally distinct vehicle to invest globally outside the former Soviet Union, with no cross-shareholding or operational overlap.
