City merger watchdog the Takeover Panel is also treating the substance of the deal as a takeover, the Daily Mail can reveal
The resulting firm, whether or not it is still called Temenos, will have a market value approaching £2bn – a level that could one day put it in a position to enter the FTSE 100 index.
On the day talks between the two were announced, Misys’ market valuation was £1.1bn, higher than the £852m valuation of Temenos.
But earlier this week it emerged that the combination of the firms would see the current chief executive and chairman of Temenos moved straight across to the same jobs in the new group.
Misys will get to nominate five of the nine members of the company’s board, and will keep chief finance officer Stephen Wilson in his role.
But Misys chief executive Mike Lawrie will walk away from the company with a £1.7m golden goodbye to join American IT group Computer Services Corporation, relinquishing the helm of the merged group to Guy Dubois.
Sir James Crosby, the former HBOS boss who chairs Misys, will also leave, but with no severance pay beyond his £180,000 basic salary. Temenos chairman Andreas Andreades will retain his role in the new firm.
Investors in Misys will own 53.9 per cent of the shares in the new company, with Temenos shareholders owning 46.1 per cent. The stock will list in London.
Temenos’ flagship software T24 is regarded as more likely than Misys’ equivalent BankFusion to be selected as the combined firm’s flagship product.
Yesterday it emerged the group would offer both products to customers, even though T24 is already the market leader.
Temenos declined to comment.
