ABG Sundal Collier AB ("ABG"), in its capacity as Sole Global Coordinator and stabilisation manager, notifies that the overallotment option granted in connection with Linjemontage i Grästorp AB’s (publ) (“Linjemontage” or the “Company”) offering of existing shares in the Company and the listing of the Company's shares on Nasdaq Stockholm (the "Offering") has been partly exercised. A total of 1,877,911 shares were exercised of the overallotment option. The stabilisation period has now ended and no further stabilisation measures will be conducted.

As announced in connection with the Offering, ABG had the option, acting as Sole Global Coordinator and stabilisation manager, to carry out transactions aimed at supporting the market price of the shares at levels above those which might otherwise have prevailed in the market. Stabilisation transactions could have been undertaken on Nasdaq Stockholm, in the over-the-counter market or otherwise, at any time during the period from the first day of trading in the Company's shares on Nasdaq Stockholm, 25 September 2026, and ending no later than 30 calendar days thereafter. However, ABG had no obligation to undertake any stabilisation measures. Transactions have not been conducted at a price higher than set out in the Offering, i.e. SEK 46.

Kalpataru Power Transmission Sweden AB ("Kalpataru Sweden") granted ABG an over-allotment option which could have been utilised in whole or in part for 30 calendar days from the first day of trading of the Company's shares on Nasdaq Stockholm to be able to sell up to 2,146,743 additional existing shares in the Company corresponding to up to 15 percent of the total number of shares in the Offering to cover any over-allotment in connection with the Offering.

ABG now notifies that the over-allotment option has been exercised corresponding to 1,877,911 shares. Thus, the remaining part of the over-allotment option that was not exercised, corresponding to 268,832 shares, will be returned to Kalpataru Sweden.

The stabilisation period in the Offering has now ended and no further stabilisation transactions will be conducted. ABG announces, in its capacity as Sole Global Coordinator and stabilisation manager, that stabilisation measures have been undertaken in accordance with article 5(4) in the EU Market Abuse Regulation 596/2014 (MAR) and the Commission Delegated Regulation (EU) 2016/1052 as specified below.

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. 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.
