R&S Group backlog hit CHF357.9m. Why did its CEO leave immediately?

R&S Group Holding AG (SIX: RSGN) has abruptly changed chief executive leadership despite reporting record demand for its transformers, with Eduardo Terzi stepping down immediately after the board and CEO developed differing views about the leadership model and organisational structure required for the company’s next stage. Group Chief Financial Officer Matthias Weibel has assumed the additional role of interim CEO while the Swiss-listed manufacturer searches for a permanent successor.

The contrast between the leadership change and the operating backdrop makes the announcement particularly significant. R&S ended June with a record CHF357.9 million order backlog, 17% higher than a year earlier, while first-half order intake reached CHF216.8 million and net sales were CHF179.2 million. The resulting 1.2-times book-to-bill ratio means incoming orders continued to exceed revenue being recognised, providing substantial visibility into 2027 and beyond.

R&S is also investing to expand transformer manufacturing capacity as electricity grids, data centres, battery-storage projects, industrial infrastructure and renewable-energy developments drive demand for electrical equipment. The board stressed that those investments remain on track and that the company’s strategic priorities and medium-term guidance have not changed despite Terzi’s departure.

That wording is important. R&S is not presenting the CEO change as a response to collapsing orders or failed financial performance. Instead, the disagreement appears to concern how the organisation should be led while growth and capital deployment become substantially more complicated.

Why did Eduardo Terzi step down when R&S Group’s transformer business is performing strongly?

R&S made the reason unusually explicit for a listed-company executive transition. The company said it became clear that the board and Terzi held differing views regarding the leadership model and organisational setup required to take R&S forward. The two sides consequently agreed that he would step down immediately.

The company did not disclose further details of those differences, so it would be inappropriate to speculate about specific disagreements over personnel, strategy or individual projects. What can be established is that the dispute emerged during a period when R&S has been expanding capacity and commercial capabilities rather than retreating from its markets.

That context may make organisational questions more consequential. A transformer manufacturer with eight plants across Switzerland, Italy, Poland, Ireland and the Middle East must coordinate manufacturing capacity, procurement, sales, investment and customer delivery across several geographies. Rapid growth can expose weaknesses in management structures that are less visible when a business is smaller.

Terzi nevertheless leaves after a period of substantial expansion. R&S generated CHF414.8 million of net sales in 2025, up 47% on a reported basis and 8.6% organically, reflecting both strong underlying demand and changes in the scale of the group.

Why does a CHF357.9 million backlog make leadership execution particularly important?

A record backlog is valuable only when a manufacturer can convert it into products, revenue and cash at acceptable margins. R&S finished the first half with CHF357.9 million of orders already booked, equivalent to roughly twice the CHF179.2 million of sales recognised during those six months. That simple comparison illustrates how much future activity is already sitting inside the production pipeline.

Delivering that backlog requires manufacturing capacity to become available at the right time. R&S has been investing in additional power-transformer capacity and commercial resources, which means management simultaneously needs to operate existing plants efficiently while commissioning capacity intended to capture future demand.

First-half EBITDA margin of 19% suggests the company is currently achieving attractive profitability while expanding. Free cash flow margin, however, was only 6.4%, illustrating why growth still needs to be managed carefully when new equipment, inventory and working capital require cash before customer orders are fully monetised.

The incoming leadership team therefore inherits a favourable demand problem rather than a shortage-of-demand problem. R&S needs to increase output without sacrificing margins, delivery performance or cash conversion.

Why are data centres making transformer capacity strategically more valuable?

Electricity demand from data centres has become another structural driver alongside grid modernisation, renewable generation and electrification. Large computing facilities require substantial power-distribution equipment, while artificial-intelligence infrastructure can increase the electrical load associated with individual campuses.

R&S specifically identified data centres, battery energy storage systems, industrial infrastructure and renewables as structurally attractive markets in its September leadership announcement. These applications require transformers and related grid equipment, extending the demand opportunity beyond conventional utility replacement cycles.

Transformer supply has become constrained in several markets because production capacity takes time to expand. Manufacturing larger units requires specialised equipment, skilled labour, engineering capability and often long customer-qualification processes, meaning competitors cannot instantly add supply simply because prices or orders become attractive.

That environment explains R&S’s capacity investment programme. If the group expands successfully while industry lead times remain elevated, additional manufacturing capability can generate meaningful growth. If capacity comes online after demand normalises, however, returns could be lower than management currently expects.

Why has CFO Matthias Weibel been asked to run the company during the CEO search?

Weibel has served as R&S Group CFO since 2022 and has been closely involved with the company for approximately five years. The board said that familiarity with the group’s development should allow him to maintain continuity while it conducts the permanent CEO search.

Giving the CFO temporary executive control makes particular sense during a capacity-investment cycle. Weibel already understands the financial assumptions behind expansion projects, current cash generation and the balance between order growth and capital spending.

The arrangement nevertheless concentrates two important roles in one executive temporarily. That can accelerate decisions during a transition, but R&S will eventually need to determine whether its future organisation benefits from again separating chief executive and finance responsibilities when the permanent succession is complete.

The board’s choice also reinforces its message that strategy remains intact. An internal executive taking temporary control is less likely to create an immediate strategic break than an external CEO brought in specifically to redesign the business.

What does the share-price reaction say about investor concern over the sudden transition?

R&S Group shares traded around CHF18.20 on September 7, down approximately 3.2% from the previous close of CHF18.80. The stock remained well below its 52-week high of CHF35.90, although daily movements in a relatively smaller Swiss-listed company should be interpreted cautiously.

The decline is understandable because an immediate CEO departure tied explicitly to differing organisational views introduces governance uncertainty even when the underlying business remains healthy. Investors now need to assess whether the disagreement was isolated to management structure or signals a broader debate about how quickly R&S should expand.

The September 16 half-year results will therefore arrive at an unusually important moment. Investors already know the headline operating metrics from the August trading update, but additional detail around margins, investment and cash flow could help clarify how much execution risk sits behind the record backlog.

R&S Group’s fundamental contradiction is unusually clean. The company has more future work booked than ever and operates in markets benefiting from electrification and AI-driven power demand. Yet exactly when that growth requires greater organisational capability, the board and CEO concluded that they did not agree on how the company should be led.
