Last private valuation of Castellum was $418M, after raising a round in October 2022 from Akelius Residential Property.


Castellum Funding Rounds

DateStageInvestorsRaisedValuationRev. MultipleDeal Summary
Oct-22SecondaryAkelius Residential Property-$418MM2 Asset Management sold 40 million shares in Castellum to Akelius Residential Property on 6 October 2022 at SEK 115 per share, a total of about SEK 4.6 billion, in a negotiated block trade agreed during Castellum's closed period with the company's consent. The sale cut M2's holding from roughly 18 per cent to 6.1 per cent of the capital and votes, and the proceeds were used largely to repay the share-backed borrowing raised against the position as falling equity markets squeezed M2's balance sheet. Castellum, which had rental income of SEK 5,723 million and net operating income of SEK 4,346 million in 2021, was reclassified in M2's accounts from an associated company to a purely financial holding.
