DateStageInvestorsRaisedValuationDeal Summary
Jul 2023Undisclosed stageMayfair Equity Partners; Morgan Stanley Investment Management$257M-OVO Energy, the UK’s fourth-largest energy supplier with over four million customers, saw Mayfair Equity Partners and Morgan Stanley Investment Management increase their stakes on July 21, 2023, in transactions worth £200m by buying shares from existing investors. These long-standing backers, involved since 2015, alongside others like Mitsubishi Corporation (20% stake), supported the company amid market recovery from the energy crisis. The investment coincided with OVO's 2022 full-year results announcement, highlighting strong underlying performance despite challenges. The stake raise followed a 90% drop in earnings before tax to £20m for the year ending December 2022, down from £159m in 2021, attributed to higher hedging costs from volatile gas prices. OVO noted no cash impact from this and expected reversal as customer energy use normalized, with compliance anticipated for financial covenants even under increased bad debts. Earlier filings had raised going concern doubts, but these were resolved. OVO, founded in 2009 by Stephen Fitzpatrick (a major remaining shareholder), grew notably after acquiring SSE Energy Services for £500m in 2019. The company focuses on retail energy supply, technology for home decarbonization, and has faced high customer complaints, topping charts in 2021 and 2023. Recent reports indicate OVO considering a strategic review in 2024, potentially hiring bankers like Rothschild for fundraising, refinancing, or partial sale, while in talks with existing lenders. Mayfair is estimated at ~30% ownership.
Feb 2019Strategic investmentMitsubishi (lead)$287M$1.3BOVO Energy, a UK-based sustainable energy retailer founded in 2009, provides digital energy services to 1.5 million customers in the UK and Germany, avoiding coal and nuclear power while generating at least 33% of its energy from renewables. The company also develops hardware like home EV chargers and energy storage systems through its intelligent energy division Kaluza. On February 14, 2019, Mitsubishi Corporation invested approximately $256 million for a 20% stake at a valuation of about £1 billion ($1.28 billion), as reported by the Financial Times. This strategic partnership aims to support OVO's international expansion into markets like France, Spain, and Australia, alongside advancements in EV charging, energy storage, and grid integration technologies. Mitsubishi Corporation, a Japanese conglomerate managing over 6.2 GW of energy capacity worldwide including renewables, lithium-ion batteries, and energy trading, views the investment as a capital alliance to promote low-carbon solutions. OVO's founder and CEO Stephen Fitzpatrick retained majority ownership post-investment, with prior backers including Mayfair Equity Partners, which took a 15% stake in 2015 for about $48 million. The funding will accelerate smart meter rollouts, digital infrastructure, and the transition to a zero-carbon energy system centered on customers, EVs, battery storage, and renewables.
Apr 2015Undisclosed stageMayfair Equity Partners (lead)$48M$307MOVO Energy, one of the UK's leading independent suppliers of domestic energy, received its first external equity investment from Mayfair Equity Partners in a Private Equity round on April 18, 2015. Mayfair has remained a long-term investor, participating in subsequent rounds including a 2023 Private Equity - II alongside Morgan Stanley Investment Management. The firm positioned OVO as a challenger in the energy sector, focusing on domestic supply. Mayfair's maiden fund, which closed at £400m in 2016, included OVO among its initial four investments alongside Fox International, Hotels & More Ltd., and others in technology and consumer sectors. Later developments show Mayfair and Morgan Stanley investing a further £200m around 2023, following their 2015 entry, as OVO reorganized including a £150m brand purchase from founder Stephen Fitzpatrick, who retained majority ownership. OVO grew to over four million customers as the UK's fourth-largest household energy supplier and Wembley Arena sponsor. Mayfair Equity Partners has since raised additional funds, including £500m Fund III, continuing investments in digital and tech-driven businesses like OVO, with 27 total investments since 2015. The firm emphasizes partnerships with management to drive growth and international expansion, supported by AI tools and process specialists.
