Pontus Boman Reflects on Rosti Group’s 80th Anniversary: A Journey of Growth and Innovation

As Chairman of the Rosti Group, I proudly reflect on our incredible journey as we celebrate our 80th anniversary. Since joining our portfolio in 2004, Rosti has embodied the core of sustainable, profitable growth, which is a key principle of the Nordstjernan Group investment philosophy.

At the time of acquisition, Rosti was a €30 million, single-site business. Today, it’s a global player with revenue exceeding €400 million, proving our strategic vision and our commitment to developing successful businesses. Our investment approach focuses on encouraging capital-efficient operations, and Rosti’s contract manufacturing model demonstrates this approach by delivering one of the strongest returns on investment in our portfolio.

As a board, we wanted to broaden Rosti’s geographic presence. Looking back maybe five years, the Chinese operations were quite dominant, generating more than 50% of the overall profit for the group. Now, Rosti has a far more balanced portfolio of sites. When you look at revenue and profit, it’s almost evenly split between the three major regions: the US, Europe, and China.

Over the years, Rosti has gone through transformational changes, expanding our presence across a variety of geographies. From entering China in 2007 to strategic acquisitions such as PCI in 2021, we have thoughtfully grown our global reach. This has not only reduced risk, but also positioned Rosti as a truly global leader in plastic injection molding.

Setting the Standard for Operational Excellence

What sets Rosti apart is our ongoing pursuit of operational excellence and our customer-first approach. During visits to Rosti’s plants, I’ve seen their state-of-the-art capabilities and unwavering commitment to innovation firsthand. From advanced manufacturing techniques to design expertise, Rosti stays ahead in the industry, guided by a decentralized model that empowers plant managers to lead their businesses independently.

When it comes to plastic injection molding, I’m extremely impressed with the level of operational excellence and how we drive this process in our various plants, and I have seen a lot of plants throughout my career.

From advanced injection molding capabilities for contract manufacturing to innovative design abilities in our Innovation Centers, I would say we’re at the forefront of the whole industry. We’re also continuously investing in and bringing new manufacturing techniques and design capabilities to the market as we go.

So if you step back and ask, why is that? How did we achieve such a shift in capability? I truly believe that the core strategy of being customer-centric—following our customers, listening to their needs, and understanding what they want—is central to this success.

Being able to deliver complete services centered around our customers’ needs—from manufacturing highly technical products to every other service we offer—is crucial. I think our combined decentralized model, where each plant manager operates with a high level of autonomy, has been a major factor behind the development of these capabilities.

Integral Role in the Nordstjernan Group

Rosti’s contributions extend beyond operational success, enriching the whole Nordstjernan Group. As a major holding, Rosti’s strong cash flow and dividends support our ability to allocate capital efficiently and manage risk. Additionally, Rosti’s progress in finance, sustainability, and operational excellence provides invaluable resources for our portfolio companies, encouraging collaboration and shared learning.

As an investment company, we also work within a decentralized model; we don’t try to centralize capabilities among our holdings because we truly believe this structure drives the business.

Looking at more functional capabilities like finance, sustainability, and CSR, as well as advances in operational excellence, I think Rosti has come a long way in its development journey—and we use this knowledge to support the broader portfolio.

We bring together the CEOs and CFOs from the Nordstjernan portfolio twice a year to share experiences and learn from each other—not just about market intelligence and how to tackle economic challenges, but also to do business together.

For operational excellence topics like Lean Manufacturing or Six Sigma, Rosti is the first place we turn to within the group. Of course, there’s always more we can do, but we don’t force it. We take advantage of these opportunities as they come up in the portfolio.

Active Ownership with Rosti Management Teams

First, at Nordstjernan Group, we want to be the driving force behind unlocking the best possible potential in the companies we invest in. We take a slightly longer-term view than management. While our management teams might have strategies for the next 3–5 years, we try to extend that perspective and ask, where will this market be in 5 years and beyond?

We’re then able to ask ourselves, “Do we really believe we can create that value over time—or what do we need to do to get more value from this business?”

A clear example of where this kind of thinking has had a significant impact is Rosti’s medical strategy. We’ve recognized an interest in entering that business because of strong underlying growth, and because we have expertise within the group and the sector itself.

So I think this is a clear effect on Rosti’s strategy, along with the acquisition of PCI to diversify the company and make it more resilient for the future.

We work closely with the management team to make sure our expectations are clear. We’re not afraid to be open and maintain a strong, ongoing dialogue.

This gives our CEOs and management teams clear direction, empowering them to make decisions confidently. It also builds a collaborative working model, so when tough decisions need to be made, our team knows they can count on me, as the owner’s representative, for support.

Building strong working relationships with the management team is vital for me. You have to build trust, be open about your ownership agenda, and be aligned on how we’re going to create value.

Building a Sustainable Future

Looking ahead, I see Rosti continuing to lead the way in the ever-changing plastics industry. As plastics become an even more important part of different industries, Rosti is positioned to drive innovation and sustainability efforts, designing with recyclability in mind and using green materials to take on tomorrow’s challenges.

Over the next 80 years, I see Rosti not just as a pioneer in plastic manufacturing, but as a beacon of sustainable growth and innovation, embodying the values and vision of the Nordstjernan Group. Together, we’ll navigate the complexities of the future, guided by our steadfast commitment to creating long-term value and building a brighter tomorrow for generations to come.
