Summary
UK private equity firm Aliter Capital has raised a £50m annex fund to finance further acquisitions by two of its existing portfolio companies, TXP and Serbus, according to the original report published by alternative assets publication AltAssets. The firm is retaining its ownership interests in both businesses while the annex capital is deployed.

The fundraise is structured as an annex to Aliter's existing fund arrangements, providing follow-on capital to two UK technology platforms that are pursuing acquisition strategies. The source material available for this story is limited, as the full article sits behind a premium subscription wall, so further detail on deal pipelines, target valuations, or the specific investors in the annex vehicle could not be verified.

For institutional allocators, the transaction illustrates a continuation-style approach in which a sponsor supports portfolio companies' add-on acquisitions through dedicated follow-on capital rather than exiting or transferring ownership.
