Investor ABFull analysis

Investor AB was born in 1916 out of a regulatory constraint: Swedish law then barred banks from holding industrial stakes on a lasting basis, so the Wallenberg bank lodged them in a dedicated company. One hundred and ten years later the model has not changed in nature. It is active long-term ownership on an open-ended horizon, spread across three pockets. Listed companies first, 72% of assets. Then Patricia Industries, which gathers the unlisted subsidiaries held at close to one hundred per cent, 19%. And the EQT pocket, 10%. The house motto sums up the posture: esse, non videri, to be rather than to seem. Strategic control is a family matter, execution is not: Jacob Wallenberg chairs the board, while Christian Cederholm has run the company since 7 May 2024 and does not belong to the family. The balance sheet carries little debt, with net debt at 1.2% of adjusted assets at 31 March 2026.

The listed pocket holds thirteen lines at 31 March 2026, and there is nothing passive about it. Investor AB owns 14.4% of ABB's capital, 17.1% of Atlas Copco for 22.3% of the votes, 30.2% of Saab for 39.7% of the votes, 21.5% of SEB, 34.4% of Sobi, 9.9% of Ericsson for 24.8% of the votes. The pattern repeats: the share of votes often exceeds the share of capital, because Swedish law allows two classes of shares, the very device that gives the Wallenberg foundations their own control over Investor AB. Concentration is real: ABB alone accounts for 17.47% of total assets, recalculated from published values.

Patricia Industries carries the companies the group owns almost entirely, overwhelmingly in healthcare: Mölnlycke at 99.7%, Laborie at 98.6%, Nova Biomedical at 99.1%, Sarnova at 95.8%, Permobil at 99.4%, BraunAbility at 95.3%. The rare feature lies in how those companies are valued. Investor AB publishes not only an estimated value per subsidiary but the earnings multiple it applies to it, from 7.1 times on Tre Skandinavien to 17.7 times on Nova Biomedical. That makes the estimate contestable: a reader can disagree with a multiple, he cannot disagree with a black box. Two lines escape that mechanism entirely, Vectura being valued on its property portfolio and the Financial Investments line by a third party.

The third pocket combines a stake in EQT AB, a listed asset manager, with commitments to twenty-six funds and co-investments run by that same manager, reported at SEK 38,523m with SEK 26,545m still to be called. A commitment is money promised and not yet paid: the manager calls it as he invests. Two reading cautions come with this pocket. Fund values are reported one quarter in arrears, as the company itself points out. And the legal ownership published in the notes is not the exposure shown in the net asset table: Permobil comes out at 91.2% legally against 99.4% of exposure, because the share held by managers through participation programmes is taken back into exposure as a receivable. Eight points of capital separate the two readings on that single line.
