"A concentration ceases to exist and the Merger Regulation ceases to be applicable if the undertakings concerned abandon the concentration. In this respect, the revised Merger Regulation 139/2004 introduced a new provision related to the closure of procedures concerning the control of concentrations without a final decision after the Commission has initiated proceedings under Article 6(1)(c), first sentence. That sentence reads as follows: ‘Without prejudice to Article 9, such proceedings shall be closed by means of a decision as provided for in Article 8(1) to (4), unless the undertakings concerned have demonstrated to the satisfaction of the Commission that they have abandoned the concentration’. Prior to the initiation of proceedings, such requirements do not apply. As a general principle, the requirements for the proof of the abandonment must correspond in terms of legal form, intensity etc. to the initial act that was considered sufficient to make the concentration notifiable. In case the parties proceed from that initial act to a strengthening of their contractual links during the procedure, for example by concluding a binding agreement after the transaction was notified on the basis of a good faith intention, the requirements for the proof of the abandonment must correspond also to the nature of the latest act. In line with this principle, in case of implementation of the concentration prior to a Commission decision, the re-establishment of the status quo ante has to be shown. The mere withdrawal of the notification is not considered as sufficient proof that the concentration has been abandoned in the sense of Article 6(1)(c). Likewise, minor modifications of a concentration which do not affect the change in control or the quality of that change, cannot be considered as an abandonment of the original concentration.
- Binding agreement: proof of the legally binding cancellation of the agreement in the form envisaged by the initial agreement (i.e. usually a document signed by all the parties) will be required. Expressions of intention to cancel the agreement or not to implement the notified concentration, as well as unilateral declarations by (one of) the parties will not be considered sufficient.
- Good faith intention to conclude an agreement: In case of a letter of intent or memorandum of understanding reflecting such good faith intention, documents proving that this basis for the good faith intention has been cancelled will be required. As for possible other forms that indicated the good faith intention, the abandonment must reverse this good faith intention and correspond in terms of form and intensity to the initial expression of intent.
- Public announcement of a public bid or of the intention to make a public bid: a public announcement terminating the bidding procedure or renouncing to the intention to make a public bid will be required. The format and public reach of this announcement must be comparable to the initial announcement.
- Implemented concentrations: In case the concentration has been implemented prior to a Commission decision, the parties will be required to show that the situation prevailing before the implementation of the concentration has been re-established.
It is for the parties to submit the necessary documentation to meet these requirements in due time." Commission Consolidated Jurisdictional Notice under Council Regulation (EC) No 139/2004 on the control of concentrations between undertakings
