I'll give my two cents which I have repetitively before.
There will be no merger. Arcam has no reason as its doing fine on its own and given the financial support of the EU bet it would not allow one in any event. Others won't buy arcam as its EBM technology right now is too limited (companies like GE are using laser more than ebm) and its easier to just buy the printers at this point and have the expansion risk to arcam. Arcam may buy smaller companies but no reason to make a sell itself to another as it makes more money by keeping its technology and production in house. Plus its obvious that Rene is really into arcam and would not like his ownership diluted.
To the extent that expansion/development financing is needed beyond cash flow, the company will simply incur debt or more probably equity financing which it authorized at the last general meeting. Since arcam does its equity issuance orderly and at market pricing, dilution and price risk will be minimized except for the overreaction of the lemmings which we have seen each time a major shareholder lightens up. We have reached new highs and we shall see how the market reacts to the ER tomorrow. I"ve given my expectations and reasoning therefore.
