BlackRock Energy and Resources Income Trust plc (BERI.L) is a UK-listed closed-end investment trust managed by BlackRock Fund Managers Limited that provides total returns to shareholders through a combination of capital growth and income by investing at least 80% of its assets in equities of companies operating in the energy and natural resources sectors, including mining, metals extraction for commodities such as copper, nickel, zinc and aluminium; traditional fossil fuel energy producers and services; renewable energy technologies; energy transition infrastructure like grid upgrades, energy storage and efficiency solutions; and integrated diversified miners. The trust allocates approximately one-third of its portfolio to renewables and sustainability-focused stocks as of August 2025, with the balance in traditional energy and mining, targeting institutional and retail investors seeking exposure to global markets across developed and emerging economies including the US, Europe, China and Australia; it pays quarterly dividends in January, April, July and October and employs selective option writing for additional income. Founded prior to its 2019 name change from BlackRock Commodities Income Investment Trust plc and headquartered at 12 Throgmorton Avenue in London, the trust maintains total assets of around £192m, a market capitalisation of £162m, gross gearing of 8% and an ongoing charge capped at 1.15% effective December 2024. Recent portfolio adjustments include reducing diversified mining exposure while increasing investments in oil and gas distribution, services, energy storage and efficiency amid valuation shifts and US policy volatility following the 2024 elections; co-managers Tom Holl and Mark Hume highlighted at the March 2025 AGM a strategic pivot toward grid investments for regulated returns, nuclear and natural gas opportunities driven by European energy security needs, and bottom-up stock picking in a tariff-impacted environment; the board continues active share buybacks, including 71,500 ordinary shares purchased on December 3, 2025 at 151.48 pence per share, to manage the share price discount to NAV averaging -9% over 12 months.
