THE ROGUE SHAREHOLDER: HOW UK BOARDS ARE LEARNING TO MANAGE ACTIVISM
The days when shareholder activism was seen as a risk only for distressed companies are over. Successful UK businesses now attract activist attention and the real test for a board is no longer whether it can resist an activist outright, but whether it can protect the company’s interests before the issue escalates.
This issue is not limited to the listed market. Family businesses, private companies and joint ventures are increasingly grappling with a related problem where a minority shareholder exercises their rights to obstruct the company’s operations or to pursue their own agenda at the company’s expense.
Whether the company is public or private, the practical question for boards is how to prevent that kind of pressure from building in the first place, and how to limit the damage once activism has actually begun.
Activist options
Understanding the risk of shareholder activism starts with evaluating the range of tools now available to an activist shareholder. Havard Law School has presented activism as a spectrum, manifested through multiple forms of behaviour.
At the mildest end is straightforward engagement: simply asking to meet the board to raise concerns. Moving along that spectrum, a shareholder may put a non-binding proposal to a vote of the wider shareholder base – a device favoured particularly by retail activists and campaign groups – either to open a dialogue or as leverage if direct engagement has stalled. At the most confrontational end, a full contest for board seats in which the activist puts forward its own slate of directors.
