Byggmästaren announced that it supports the proposed merger between its portfolio company Infrea and Netel. As part of the transaction, Byggmästaren will invest 10 MSEK in a new share issue and become the largest shareholder in the combined entity with a roughly 13-14% stake. We consider the move as directionally right for Byggmästaren — low cost, contained downside, and consistent with its active-ownership model — while we believe the actual value creation is a bet on integration rather than a given. As Infrea is a listed holding marked to market in both Byggmästaren's NAV and our derived NAV, the announcement triggers no direct change to our estimates. At the exchange terms, the stake converts to ~89 MSEK (~99 MSEK including the 10 MSEK investment) and remains ~5% of NAV.

Sensible structure, but the upside is an integration bet

Under the proposed terms, Infrea's shareholders will receive 17 Netel shares for every 4 Infrea shares, creating a combined Nordic infrastructure group with approximately 5 BSEK in revenue. Pre-close, which is expected to occur in Q4'26, Byggmästaren's exposure to Infrea will float with Netel's share price rather than its own, where the quote should simply track 4.25 × Netel less a deal-risk spread.

We have previously highlighted that Infrea, which represents around 5% of Byggmästaren's NAV, has struggled with weak margins in recent years, and that structural change or a potential exit was the most likely long-term outcome. Following the balance sheet repair from the late-2025 divestment of its Water & Sewage business, we see the Netel merger as a commercially rational step. We believe the merger addresses Infrea's lack of scale, a persistent headwind in the highly competitive, low-margin civil engineering market. In addition, we consider the fit is genuinely complementary, with Infrea's civil and paving operations sitting alongside Netel's power and telecom, letting the group take more whole-project responsibility and capture a larger share of each contract, while Netel adds Norway and Germany to Infrea's Sweden. Management guides to ~50 MSEK of cost synergies within 12–24 months, with revenue synergies and a more diversified, lower-concentration order book over time.

However, in our view, execution is the swing factor, and the merger is not without risks. The combined adjusted EBITA margin is thin at ~1.7%, and the ~50 MSEK synergy target is large relative to the group's ~83 MSEK of combined adjusted EBITA. More importantly, Infrea is merging with a partner that has struggled recently. Netel posted an operating loss and ~63 MSEK of project write-downs in 2025, and maintains a stretched balance sheet (Net debt/EBITDA of 9.7x in Q1'26) that the rights issue repairs but does not fully eliminate. In our view, the combined equity story rests, at least near term, on three contingent legs: cost-synergy delivery, Netel margin normalization, and as-yet-unquantified revenue synergies, stacked on a geared balance sheet. We therefore think the deal warrants healthy skepticism rather than immediate applause.

Minor capital commitment with retained influence

Prior to the merger, Netel will conduct a fully guaranteed rights issue of 127 MSEK, with a potential over-allotment of up to 75 MSEK. Byggmästaren has committed to subscribe for 10 MSEK in this issue. Depending on the final outcome of the issue, Byggmästaren will hold between 12.6% and 13.9% of the new company, making it the largest single shareholder. Byggmästaren's CEO, Tomas Bergström, will also take the role of Vice Chairman on the new board. In our view, the 10 MSEK capital commitment is negligible given Byggmästaren's strong liquidity position of 465 MSEK (235 MSEK cash + 230 MSEK undrawn credit facilities) at the end of Q1. While Byggmästaren's ownership percentage decreases from its current 20% in Infrea, we believe becoming the anchor shareholder in a larger, more liquid entity provides a potentially clearer path for value creation and eventual liquidity than Infrea could have achieved on a standalone basis.
