While parts of the private equity industry have faced a challenging dealmaking environment in recent years, Nordic mid-market buyout manager Summa Equity has navigated with resilience, underpinned by its thematic focus across four investment areas backed by strong, secular tailwinds: Circularity, Sustainable Food, Energy Transition, and Tech-Enabled Resilience. As Summa Equity celebrates its 10-year anniversary this year, founder Reynir Indahl believes those tailwinds will be stronger than ever in the years to come.
“The areas that we are focusing on are even more attractive today,” says Indahl, founder and managing partner of Summa Equity. “If you look at the problems we face around waste, our broken food system, energy dependence, and fragile infrastructure, it is surprising that anyone could doubt that investing in companies solving these challenges is a powerful investment strategy.” Over the past decade, Summa Equity has grown into a firm of 80 professionals, raised close to €4 billion across three funds and a co-investment vehicle, and established itself as one of the leading thematic private equity investors in the Nordics and Europe.

When Summa Equity was founded in 2016, impact investing was still viewed with a considerable degree of skepticism. Many investors associated sustainability-focused strategies with lower returns, believing that generating positive environmental or social outcomes required sacrificing financial performance.
“The whole sustainability field became much more popular a few years after we started,” recalls Indahl. While investor interest in sustainable investing has grown significantly since then, expectations have also evolved. Investors remain keen to allocate capital to businesses addressing societal challenges, but they are no longer willing to sacrifice returns in the process. “Sustainability was never viewed as a compromise on returns, but rather as a source of long-term competitive advantage. This was the premise from the day Summa Equity was launched,” says Indahl.
Investment Process: Starting With the Problem
Unlike many private equity firms that begin by screening companies, Summa Equity starts by identifying large-scale societal and economic challenges. “Within each of our themes, we always start with what’s the problem we’re trying to solve,” explains Indahl.
In the area of circularity, for example, the team examines the scale of waste generation and the transition toward a more circular economy across Europe. “Once we have developed that thesis, it informs where the opportunity set is, where we can pursue consolidation through buy-and-build strategies, and where we see strong organic growth.” This top-down approach allows Summa Equity to identify sectors well-positioned to benefit from long-term megatrends before narrowing its focus to individual companies capable of capitalizing on those opportunities.

Through the current higher interest-rate environment, Summa Equity remained active on both acquisitions and exits. “We have found the market attractive again over the last few years and have completed several exits at very strong outcomes and deployed more than €1 billion since 2024,” says Indahl.
Geopolitical developments, including Russia’s invasion of Ukraine and the broader push for European self-sufficiency, have only reinforced the relevance of the firm’s investment themes. “The four areas that we invest in have become increasingly critical as Europe strives for greater self-sufficiency and sovereignty,” argues Indahl. “We have seen a lot of attractive opportunities in our sectors. It has not been a constraining market for us.”
Operational Value Creation at the Core
While higher interest rates have weighed on transaction activity, they have also highlighted the importance of operational value creation. As financing costs have increased and leverage has become less powerful as a return driver, firms across the industry have been forced to place greater emphasis on operational value creation. For Summa Equity, however, this shift represents more of a validation of an approach it has followed from the outset.
“We are very strategic and operational in how we create value in our companies. This has been a cornerstone from the start,” says Indahl. The firm’s investment model has always been built around identifying businesses with strong structural growth prospects and then helping management teams accelerate growth, improve operations, and strengthen market positions.
“Those that have relied more heavily on debt and balance-sheet engineering to generate returns are realizing that this has become more difficult and are now having to focus on other levers for value creation.”

Indahl does, however, observe a broader shift among private equity peers. “Those that have relied more heavily on debt and balance-sheet engineering to generate returns are realizing that this has become more difficult and are now having to focus on other levers for value creation.”
Energy Transition Emerging as a Larger Opportunity
Despite energy transition being one of the most significant long-term trends globally, it has historically represented the smallest area of capital deployment within the firm’s portfolio. “For good reason,” acknowledges Indahl. “Much of the sector was still emerging, unprofitable, heavily subsidized, and we are not infrastructure investors.”
Rather than investing directly in renewable energy projects, Summa Equity focused on businesses helping customers improve energy efficiency and strengthen critical infrastructure. “We have invested in suppliers to the European grid, particularly on the software, components, and data side.”
“Now that much of the renewable energy space has shifted toward profitability, largely because of how significantly costs have come down, we see many more interesting opportunities across the energy sector.”

As renewable technologies have matured and economics have improved, the energy transition has become increasingly attractive from a private equity perspective. “Now that much of the renewable energy space has shifted toward profitability, largely because of how significantly costs have come down, we see many more interesting opportunities across the energy sector,” says Indahl. “We expect to invest considerably more in energy going forward because it has become much more attractive over the past few years.”
Building an Anti-Fragile Portfolio
Despite ongoing uncertainty driven by artificial intelligence, geopolitical tensions, inflationary pressures, and shifting trade relationships, Indahl remains optimistic about the outlook for Summa Equity’s investment strategy. In fact, he believes the current environment reinforces the rationale behind the firm’s thematic approach.
“If you invest in profitable companies providing solutions to real-world problems, they are likely to outperform in a more challenging world.”

“We live in an incredibly uncertain world,” he says. “The reason I am even more excited about our investment strategy today is that we focus on anti-fragility.” The concept is central to how Summa Equity thinks about portfolio construction. While some sectors may struggle as new sources of uncertainty emerge, Indahl believes companies addressing essential challenges in waste management, food systems, energy security, and critical infrastructure are positioned to remain relevant and grow regardless of market conditions. “We need to address these issues irrespective of how the world around us evolves,” he concludes. “If you invest in profitable companies providing solutions to real-world problems, they are likely to outperform in a more challenging world. That is what our portfolio has demonstrated these last 10 years and we have only just begun.”
