Shares in contract electronic manufacturer AB Electronic Products Group Plc leaped 15 pence to 93 pence on London’s International Stock Exchange yesterday after the Abercynon, South Wales company announced that it had received a merger proposal from TT Group Plc, the company that finally won the fierce bid battle for Crystalate Plc. AB Electronics said it was consulting its financial adviser N M Rothschild & Sons Ltd and was seeking clarification of TT’s intentions. TT Group has bought 6.35% of AB’s equity in the market, and AB indicated that it was prepared to talk: the board of AB Electronic recently announced a clearly defined strategy for the development of its core businesses and has declared an intention to seek partners who can add further momentum towards the achievement of that strategy, the company noted in a holding statement.
