ROCKWOOL A/S Reports Latest Transactions Under Its Ongoing Share Buy-Back Programme

On 21 January 2026, ROCKWOOL A/S released an official announcement regarding its transactions executed in connection with its ongoing share buy-back programme. The report, identified as Company Announcement No. 05 – 2026 and submitted to Nasdaq Copenhagen, provides a comprehensive update on the share repurchase after its last communication to the market. In accordance with the Safe Harbour regulations outlined by the European Union, ROCKWOOL A/S continues to strategically repurchase its own shares as part of its long-term capital allocation and shareholder return initiatives.

Overview of the Share Buy-Back Programme

In its formal market communication, ROCKWOOL A/S confirmed that the Company initiated a share buy-back programme on 7 February 2025, which is scheduled to run until 5 February 2026. Under this programme, the Company is authorised to repurchase its own ordinary B shares for a total maximum value of €150 million. The buy-back initiative is being carried out under the EU’s regulatory framework for share repurchases, which includes:

• EU Commission Regulation No 596/2014 of 16 April 2014, and
• EU Commission Delegated Regulation No 2016/1052 of 8 March 2016 (“Safe Harbour”).

These regulations are designed to allow listed companies to repurchase shares on regulated markets such as Nasdaq Copenhagen in a transparent and compliant manner.

Period Covered by the Announcement

The latest buy-back summary covers transactions carried out from 14 January to 20 January 2026. These detailed transaction records serve to inform investors, regulatory bodies, and the broader market about the exact volume and value of shares repurchased during this period.

Weekly Transaction Breakdown

The following transactions were executed over the five trading sessions covered in this announcement. Each line item reflects the number of B shares purchased, the average price per share paid in Danish kroner (DKK), and the aggregate transaction value in DKK:

These transactions increased the aggregate number of shares repurchased under the programme to 4,319,500 B shares, amounting to DKK 1,113,220,856 in combined purchase value for the cumulative period covered by previous announcements and this reporting period.

Total Stake of Shares Held by ROCKWOOL A/S

Following the buy-back activities reported for this period, ROCKWOOL A/S now directly holds 4,766,356 B shares. These holdings represent approximately 2.25% of the Company’s total share capital, reflecting the Company’s ongoing commitment to optimise its capital structure and return value to shareholders through disciplined repurchase strategies.

Importance of the Buy-Back Strategy

Share buy-backs are widely recognised as an important tool for companies to enhance shareholder value. When a company repurchases its own shares, the total number of shares outstanding in the market is reduced. This means that earnings and assets are spread over fewer shares, potentially increasing key financial metrics such as earnings per share (EPS) and return on equity (ROE). For investors, repurchases can signal confidence by management in the company’s long-term prospects and capital strength.

In the case of ROCKWOOL A/S, this programme also provides disciplined, regulated execution of share repurchases over a defined period, ensuring that buy-backs are aligned with market best practices and regulatory requirements.

Regulatory Compliance and Safe Harbour Rules

The buy-back programme adheres to the EU’s so-called Safe Harbour regulations. These rules allow companies to repurchase shares on regulated markets in a manner that reduces the risk of market manipulation and ensures a level of transparency and fairness for all market participants. By following both Regulation No 596/2014 and Delegated Regulation No 2016/1052, ROCKWOOL A/S demonstrates compliance with EU financial market integrity standards.

Safe Harbour rules specifically govern how and when share purchases can be made, such as maximum daily volume limits and required disclosures of executed trades. Through consistent reporting like this announcement, ROCKWOOL A/S ensures transparency to the market and investors.

Additional Information and Attachments

In the original press release, reference documents and detailed transaction summaries are attached. These include official company announcements and detailed transaction data files that provide transparency and audit traceability. Investors and stakeholders can consult these files for precise verification of the transactions reported.

Outlook and Closing Remarks

ROCKWOOL A/S’s ongoing buy-back programme represents both a disciplined capital allocation initiative and a strategic approach to returning value to shareholders. As the programme continues through to 5 February 2026, the Company remains committed to providing updates on repurchase activities in line with market disclosure requirements. Investors and analysts will be watching subsequent announcements for both volume and pricing trends, as well as any potential adjustments to the programme’s scope.
