Brunswick will handle financial comms around the listing of global depository receipts (GDRs), which is set to take place in the middle of next year around the same time as a partial flotation of Rosneft on the Russian stock market.
GDRs are negotiable certificates held in the bank of one country, which represent a specific number of shares of a stock traded on an exchange in another country.
Using a GDR listing helps firms raise money quickly and cheaply without having to meet the London stock market's onerous corporate governance and audit rules.
Rosneft is Russia's third-largest oil and gas company with assets worth up to £33bn.
Earlier this year a Russian government-backed attempt to fold Rosneft into Gazprom, the country's biggest company, was abandoned. But a plan to increase government control of the Russian energy sector by acquiring more than 50 per cent of Gazprom through Rosneft is still going ahead.
