Pursuit Dynamics shares crash 79% after Procter & Gamble deal fails

Shares in Pursuit Dynamics crashed 79% after the technology firm admitted a hoped-for deal with Procter & Gamble will not go ahead. The fall on Monday followed a tumultuous few days for Pursuit Dynamics' shares last week. On Friday it was forced to put out a statement saying it knew "no reason" for its share price to fall 30% over two days. The firm, whose products improve the mixing of liquids from toothpaste to beer, then said on Monday morning that P&G would not be using its products. It is understood the company did not learn of P&G's decision until Friday evening. The shares closed at 14.75p on Monday, down from a high of more than 600p two years ago.
