ROCKWOOL lifts growth forecast to 5%–7% as record sales outweigh higher energy and transport costs

ROCKWOOL A/S reported record second-quarter revenue of €1 billion as stronger insulation volumes and market-share gains pushed sales 10% higher year over year. EBITDA increased to €208 million and EBIT rose 3% to €129 million, while management raised its full-year 2026 revenue-growth outlook to 5%–7% from 3%–6%. The stronger top line nevertheless came with a decline in profitability, as Q2 EBIT margin fell to 12.9% from 13.8% and EBITDA margin slipped to 20.8% amid rising energy and transport costs. ROCKWOOL also lifted planned 2026 investment to approximately €750 million from €700 million, leaving investors to weigh stronger demand against a more expensive growth and manufacturing environment.

The results were stronger than analysts had expected on several headline measures. ROCKWOOL’s pre-results consensus called for approximately €948 million of Q2 revenue, €199 million of EBITDA and €126 million of EBIT, meaning the company exceeded all three averages with €1 billion of revenue, €208 million of EBITDA and €129 million of EBIT. However, management maintained its full-year EBIT-margin guidance at 13%–14%, signaling that the revenue beat does not automatically translate into a comparable profitability upgrade.

The market reaction reflected that distinction. ROCKWOOL’s more actively traded B shares were around DKK215.20 on August 19, down roughly 3.8%, while the company’s own investor page also showed significant weakness in its Copenhagen-listed shares during the session. Before the results, analysts had an average 12-month price target of DKK233, with 11 of the 15 recommendations classified as Buy or Overweight, suggesting sentiment entered the quarter relatively constructive.

ROCKWOOL’s record Q2 sales show insulation volumes are recovering faster than expected

Revenue reached exactly €1 billion during Q2, representing 10% growth in both reported terms and local currencies. ROCKWOOL attributed the increase primarily to higher volumes, including market-share gains in flat-roof projects as the pricing gap between stone wool and competing insulation materials narrowed.

Geographically, management highlighted particularly strong performance in South and Eastern Europe, Asia and the United States. That breadth is encouraging because it suggests the quarter was not dependent on one unusually strong construction market, with demand improving across several regions despite continued uncertainty in parts of the global building sector.

The first-half numbers show how sharply momentum improved during Q2. H1 revenue reached €1.906 billion, up 6% in local currencies and 5% in reported terms, after Q1 revenue had been €906 million and essentially flat in reported currency. The difference implies that Q2 provided a meaningful acceleration rather than merely extending the subdued growth seen at the beginning of the year.

Management expects that momentum to continue through the second half, which is why 2026 local-currency revenue-growth guidance has been raised to 5%–7%. ROCKWOOL had entered the year expecting only 2%–4% growth, increased that range to 3%–6% after Q1 and has now raised it again following the record second-quarter performance.

That sequence is significant because it shows the demand environment improving more quickly than ROCKWOOL initially expected. At the same time, part of the future revenue increase will come from price rises introduced to compensate for inflation in energy and raw materials, meaning reported sales growth will increasingly combine genuine volume expansion with inflation recovery.

Energy and transport inflation explain why record revenue failed to produce stronger margins

ROCKWOOL generated €208 million of Q2 EBITDA, giving it a 20.8% margin, while EBIT increased to €129 million. Both earnings measures remained healthy in absolute terms, but Q2 EBIT margin declined 0.9 percentage points year over year to 12.9%, showing that higher sales volumes were not enough to fully neutralize the increase in operating costs.

The first-half pattern was similar. EBITDA reached €395 million with a 20.7% margin, while EBIT totaled €249 million and EBIT margin fell 1.5 percentage points to 13.1%. Management nevertheless continues to describe that level as satisfactory and has retained its 13%–14% full-year EBIT-margin forecast.

Energy prices are especially important for ROCKWOOL because manufacturing stone wool involves high-temperature melting processes. Rising transport expenses add another layer of pressure because insulation products are bulky, making freight economics materially relevant to delivered margins even when factory utilization and sales volumes improve.

Management is responding with additional price increases intended to offset inflation in energy and raw materials. Those measures should support second-half margins, but ROCKWOOL warned that the benefit will be partly countered by North American sourcing constraints, higher maintenance expenses and a less favorable mix across products and countries.

North America is particularly important because management expects sourcing limitations to restrict the amount of revenue growth the region can capture. The company had already identified weakness in Canada and higher logistics costs earlier in the year, while U.S. demand has since strengthened enough to become one of the geographic highlights of Q2.

The margin debate therefore comes down to whether pricing and productivity can catch up with cost inflation without slowing the volume gains now supporting revenue. ROCKWOOL’s unchanged full-year margin outlook suggests management believes the answer is yes, but today’s stock decline indicates investors want more evidence before treating record sales as a full earnings reset.

€750 million investment plan shows ROCKWOOL is prioritizing capacity and electrification despite cost pressure

ROCKWOOL increased its expected 2026 investment level to approximately €750 million excluding acquisitions, up from the €700 million forecast after Q1 and €650 million anticipated at the beginning of the year. First-half investments had already reached €353 million, an increase of €182 million from the comparable period.

Management said the latest increase primarily reflects the timing of commitments and down-payments associated with major investment projects rather than an unexpected deterioration in existing assets. The company continues to invest in capacity expansion, factory electrification, automation and digital initiatives as it seeks to increase production while lowering the long-term carbon intensity of stone-wool manufacturing.

Earlier 2026 investments included factory projects in the United States and India, additional capacity in Romania, electrification of production lines in the Netherlands and France, logistics automation in Germany and a new technical-insulation production line in the United States. Those projects illustrate how the capital program combines geographic expansion with manufacturing modernization rather than focusing solely on replacement spending.

ROCKWOOL also acquired the remaining stake in Swedish company ScanArc Plasma Technologies in June. Management linked the acquisition to its longer-term objective of developing fossil-free melting technology while strengthening internal technical capabilities, making the transaction strategically related to the same energy-cost and decarbonization challenges currently affecting margins.

The higher spending creates a near-term cash-flow tradeoff. ROCKWOOL had already reported negative €119 million of free cash flow in Q1 as investments increased and tax timing affected cash generation, while net interest-bearing debt stood at €306 million with leverage of only 0.4 times, indicating that the balance sheet still had substantial capacity to support the expansion program.

Investors therefore appear less concerned about whether ROCKWOOL can finance the projects than about the returns those projects will eventually generate. A €750 million annual investment program makes sense if rising insulation demand, energy-efficiency regulation and market-share gains support sustained volume growth, but the projects need to produce enough future earnings to justify the capital being committed today.

Higher 2026 sales guidance raises the earnings bar as investors focus on second-half margins

ROCKWOOL now expects 5%–7% local-currency revenue growth during 2026 while maintaining an EBIT margin of 13%–14%. At the midpoint, the sales forecast is stronger than the 5.4% growth analysts expected before the Q2 release, although the company’s margin target remains broadly aligned with the prior consensus expectation of 13.6%.

The company’s Q2 revenue of €1 billion also exceeded the highest point of the analyst consensus range, which ran from €922 million to €978 million. EBITDA of €208 million was above the €199 million consensus average, while EBIT of €129 million modestly surpassed the €126 million expectation.

Those comparisons reinforce why the negative stock reaction is notable. Investors are not selling because ROCKWOOL missed revenue or earnings expectations, but appear instead to be focusing on the cost required to generate the stronger growth and on whether EBIT margins can remain within the targeted range while energy, logistics and maintenance expenses remain elevated.

Another important adjustment is the removal of ROCKWOOL’s Russian operations from current results. The company lost control of that business on January 13, 2026, and has restated relevant 2025 profit-and-loss and cash-flow comparisons to exclude Russia, making the current growth figures more representative of the continuing business.

The underlying demand story remains supportive. Higher energy prices increase the economic incentive for building owners to improve insulation, while fire safety and energy-security concerns add longer-term structural reasons for upgrading building envelopes. ROCKWOOL’s market-share gains in flat roofing suggest the company is capturing some of that demand rather than simply benefiting from a broader construction rebound.

The next test will be whether price increases and production efficiencies can keep EBIT margin inside the 13%–14% range while record sales continue. If margins stabilize as second-half volumes remain strong, the current share-price weakness could look disconnected from improving fundamentals, but another round of cost pressure would reinforce investor concern that revenue is currently growing faster than economic profitability.
