The Stabilisation Manager may effect transactions in order to maintain the market price of the shares at levels above those that might otherwise prevail in the open market.

In no event will transactions be effected at levels above the final price in the Offering. No later than by the end of the seventh trading day after stabilisation transactions have been undertaken, it shall be made public that stabilising measures have been performed in accordance with article 5(4) in MAR. Within one week of the end of the stabilisation period, the Stabilisation Manager will make public whether or not stabilisation measures were undertaken, the date at which stabilisation started, the date at which stabilisation last occurred as well as the price range within which stabilisation was carried out for each of the dates during which stabilisation transactions were carried out. Except as required by law or regulation, the Stabilisation Manager will not disclose the extent of any stabilisation and/or over-allotment transaction carried out in relation to the Offering.

About Linjemontage
Linjemontage is a Swedish pure-play EPC provider within power infrastructure, enabling the modernisation and expansion of the electricity grid in Sweden and Norway. With over three decades of experience, the Company has established one of the leading positions in Sweden in terms of market share and profitability. Linjemontage is one of few EPC providers in Sweden focused exclusively on energy, delivering projects within substations and transmission and distribution networks across the full voltage range. Its customers include national transmission system operators such as Svenska kraftnät and Statnett, regional distribution companies such as Ellevio, Vattenfall Eldistribution and E.ON, and industrial customers such as Volvo and LKAB, as well as data centres.

The Company is active in two principal areas of power infrastructure: substations, and transmission and distribution networks. Its portfolio spans both newbuild projects and refurbishment of existing assets. Linjemontage has extensive experience in designing and constructing substations up to 400 kV and believes it is among the few contractors that can deliver cable projects up to 400 kV.[3] Typical substation and transmission projects range from approximately SEK 50 million to SEK 500 million, while larger transmission projects sometimes exceed SEK 500 million.

Founded in 1993, Linjemontage has gradually evolved from a regional grid services provider into a specialised Swedish EPC contractor operating in the electricity grid market in Sweden and Norway with strong high-voltage capabilities. The Company operates from 19 offices in Sweden, two in Norway and one in Croatia, and has recently established an operation centre in India expected to provide engineering support to projects in Sweden and Norway. In 2024, Linjemontage won its largest project to date, a transmission project for Svenska kraftnät valued at approximately SEK 1 billion, followed in 2026 by a 400 kV substation project for Svenska kraftnät valued at approximately SEK 779 million.

For the financial year ended 31 March 2026, Linjemontage's net sales amounted to SEK 3,225 million, with an adjusted EBITA of SEK 245 million, corresponding to an adjusted EBITA margin of 7.6 percent. As of 30 June 2026, the Company had an order book of SEK 4,349 million. Financial information for the financial years ended on 31 March 2025 and 31 March 2026, respectively, and the three months ended 30 June 2026 (including comparative figures for the corresponding period in 2025) will be included in the prospectus.
