Ten firms heading for a value-boosting demerger

published 1 March 2006

A recent piece of academic research has proved what many have long suspected, says Shares: "that while mergers and takeovers mainly bring questionable benefits to the companies and their shareholders, demergers by and large add value".

This is especially true when a large parent firm spins off a smaller unit; in later trading, shares in the spin-offs outperformed those of their peers by 17% and "substantially" outperformed the broader market.

UBS found that £12,000 invested equally in 12 stocks prior to their demerging "would have turned into £21,120 by 2005", a return of 76%. Of course, this strategy isn't fail-safe Northern Foods and Uniq are both cases of companies where the results of a demerger have been "disappointing". But there have been many successes (ICI/Zeneca, BT/O2, Kingfisher/Woolworth/Kesa, Bats/Argos, Granada/Compass and BG/Lattice, to name but six) where both new entities have benefited enormously from a new ability to focus on their core businesses.
