Ratos — A Fragmented but Cash-Flow-Strong Group in Transformation
Ratos is a long-held investment that we believe is misunderstood and where we now expect and hope for a turnaround in the share price.
Ratos – From Hero to Zero and on the Way Back Again
Under the leadership of Arne Karlsson (1999–2012), Ratos was transformed from a traditional investment company into a private equity-like firm with a focus on active ownership and business development. After stepping down as CEO in 2012, he remained on the board until 2016. During Karlsson’s tenure, Ratos became a true stock market darling and was regarded as one of the finest companies on the exchange.
Susanna Campbell joined Ratos in 2003 and became CEO in February 2012. She left the role in June 2016 in connection with a strategic shift. Her tenure was marked by weak portfolio performance, expensive acquisitions, and few major exits. Companies such as AH Industries, Jøtul, and Euromaint underperformed, and the stock price fell by over 30%. She was succeeded by Magnus Agervald in July 2016, who remained for only 1.5 years.
Current CEO with a Stellar Track Record from ÅF (2002–2017)
Jonas Wiström then took over as CEO after 15 years at the helm of the engineering consultancy ÅF (Ångpanneföreningen) from 2002 to 2017. During those 15 years, he executed an impressive transformation of the company – in terms of size, profitability, and strategic direction. Under his leadership, ÅF’s revenue grew from around SEK 2 billion to over SEK 10 billion. This was achieved through a combination of organic and acquired growth. The share price rose from under SEK 12 to around SEK 200, corresponding to an average annual return of 20.6% (excluding dividends).

Strategy and Direction
When Jonas Wiström took over as CEO in 2017, Ratos was a highly leveraged and fragmented company. The focus shifted to improved profitability, annual EBITA growth, and a leverage ratio below 2.5x EBITDA. Through cost savings, a new leadership culture, and restructuring, debt levels were significantly reduced, which enabled new acquisitions starting in 2021.
Streamlining and Portfolio
Shifts Ratos has gradually transformed towards three core areas: industry, technical solutions, and infrastructure services. Weak holdings such as Jøtul and Gudrun Sjödén were divested early. New acquisitions – such as Semcon, Knightec, and Expin – have complemented the portfolio. The merger of Semcon and Knightec into Knightec Group, and the spin-off of Aleido, demonstrate the strategy: fewer, larger, and more focused companies. The sale of Airteam in 2025 is a first step in the declared streamlining process.
Handling of Problematic Holdings
Plantasjen has undergone tough efficiency measures and a restructuring in 2024. The store network has been downsized and the focus is now on restoring profitability. Expin, acquired in 2022, turned out to have serious accounting irregularities. Ratos increased its ownership to 94%, filed a police report against the former management, and restructured the company to focus on profitable railway electrification. Diab has been repositioned after weak demand in the wind power segment. In general, Ratos under Wiström has shown a willingness to both divest weak companies and invest in core assets with turnaround potential.
Financial Performance
Under Wiström, EBITA has increased from around SEK 425 million (2018) to SEK 2,329 million (2024), a fivefold increase. The adjusted EBITA margin for 2024 amounted to 8%.
Free cash flow in 2024 reached SEK 2.1 billion (around 90% conversion), with a sustainable long-term level of approximately 70%.
Net debt/EBITDA has dropped from 3.4x to 1.2x, and dividends have been able to increase.
Organic growth in 2024 was weak (-5%) due to Plantasjen, but several portfolio companies are growing.
Ratos Today: Fragmented at First Glance
Ratos consists of three business areas: Industry, Construction & Service, and Consumer, of which the first two represent the core operations and currently generate all profits.

Revenue Distribution – Mixed but Concentrated
Revenue is unevenly distributed, with Sentia accounting for about one-third of the group’s total revenue, followed by Plantasjen, Knightec, Presis Infra, HL Display, and Aibel, each contributing approximately 10%. In addition to these, there are several smaller companies contributing less, which adds to the group’s fragmented appearance. However, this also means that the majority of the company’s revenue is anchored in a few relatively stable businesses
Decent Profitability and Strong Cash Flows from a Stable Core Portfolio
In 2024, the Ratos Group reported total revenue of SEK 32 billion with an EBITA margin of 8%. Five of the group’s holdings – Sentia, Presis Infra, Aibel, HL Display, and Knightec – together account for a full 80% of the group’s EBITA.
The EBITA level for 2024 should be considered depressed due to write-downs in Plantasjen and Expin totaling over SEK 800 million. At the same time, the restructuring efforts carried out – primarily in Plantasjen – point toward a more profitable core going forward.
Seemingly High Quality in the Most Important Subsidiaries
Sentia and Presis Infra account for a significant portion of Ratos’ profits. Based on available data, the quality of these companies appears to be high, as outlined below.
HENT (85% of Sentia)
Construction company based in Norway. Example projects include:
Norway’s largest university building: the Life Sciences Building
Two blocks of the new government quarter in Oslo
Sections of the Fornebu Line
The Norwegian Ocean Technology Center
-
Hospital projects – six currently ongoing Aker’s new headquarters, which will also be the largest office building in Norway
According to Ratos, Sentia as a whole should be able to maintain an EBITA margin around or slightly above 5%. The company has fully exited residential development and is now focused on public-sector buildings, which contributes to stability in demand. Our impression is also that the company applies conservative revenue recognition, reducing the risk of unexpected negative surprises.
Presis Infra
Presis Infra is a Norwegian corporate group based in Bergen, specializing in infrastructure maintenance, with a leading position in its industry in Norway. The company also operates in the maintenance of ferry terminals and rockfall protection. Presis is known for its lean organization, decentralized business model, and is unique in its sector for achieving leading margins. Since Ratos acquired its stake, the company has grown organically by over 20% annually on average. Profitability has also been strong, with a consistently high EBITA margin above 13% and historical cash conversion of 90% of EBITA.
Strong Balance Sheet and Solid Cash Conversion
Cash conversion was strong in 2023 and 2024, ranging between 90% and 130% of EBITA – driven by improved working capital. Over the longer term, a more normalized conversion range around 65–70% is expected. The weaker levels in 2021–2022 (4% and 35%) were largely due to high CAPEX and inventory buildup. Since 2023, investments have decreased to healthier levels, around SEK 200 million per year. We view this as a normalized level. The company has also strengthened its balance sheet. After the sale of Airteam in March 2025, net debt stands at around 0.5x EBITDA – a low level that provides flexibility for future investments or opportunities.
Ongoing Internal Streamlining and Structural Changes
Beneath the surface, Ratos today operates as a relatively well-functioning company, although the portfolio still appears somewhat fragmented. However, streamlining is steadily progressing:
Airteam was sold in March 2025
Aibel, which contributes just under SEK 450 million in EBITA, is the only holding with minority ownership (49%) and is expected to be listed once the IPO market improves. The company also had a net cash position of NOK 1.9 billion at year-end. If Aibel were sold or listed at 7x EBITA (excluding cash), Ratos’s share would be worth approximately SEK 4 billion – compared to the current enterprise value of around SEK 11 billion. This would significantly unlock hidden value in Ratos.
Plantasjen has undergone an extensive restructuring – 36 of 125 stores have been closed and lease agreements renegotiated. The remaining business is expected to become more profitable and then positioned for divestment. In a conservative scenario, the business could generate over SEK 3 billion in revenue and EBITA of SEK 150–200 million. Ideally, this unit could be sold for over SEK 1 billion within a year.
Expin Group has also been restructured, with four subsidiaries shut down. The remaining business is expected to generate around SEK 700 million in revenue and return to profitability, making it an insignificant part of Ratos going forward. The remaining unit is focused on electric infrastructure, including maintenance of railways, trams, and metro systems.
Once the dust settles, the remaining structure is expected to mainly consist of the Construction & Services segment (led by Sentia and Presis Infra) and Industry – the latter still relatively diversified but stable.
Construction and Infrastructure as the Core of Future Streamlining
The construction sector is particularly important to the group. Sentia and Presis Infra together account for around SEK 1 billion in EBITA.
Sentia focuses on critical public construction in the Nordics – including schools, hospitals, and police stations
Presis Infra specializes in the maintenance and development of railways, roads, and energy – part of the growing field of Critical Infrastructure
Construction and Infrastructure as the Core of Future Streamlining
At a share price of around SEK 32, Ratos is trading at approximately 7.5x free cash flow, providing a solid valuation floor. If the company succeeds in demonstrating that Plantasjen and Expin are sustainably profitable post-restructuring, a multiple of 10–12x FCF would be fully reasonable – implying significant revaluation potential.
Summary: Solid Foundation, Undervalued Upside
Ratos offers a combination of improved profitability, strong cash generation, low leverage, and ongoing portfolio streamlining. A few high-quality holdings drive the majority of value creation. Once the effects of the restructurings in Plantasjen and Expin start to materialize in the financials, there is good reason to believe in a valuation uplift from today’s level of around 7.5x free cash flow.
Ratos currently represents 4.8% of the Kavaljer Investmentbolagsfond.
