Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On July 13, 2014, Mylan Inc., a Pennsylvania corporation (“Mylan”), entered into a Business Transfer Agreement and Plan of Merger (the “BTA”) by and among Mylan, New Moon B.V., a private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) organized under the laws of the Netherlands (“New Mylan”) and a wholly-owned subsidiary of Mylan, Moon of PA Inc., a Pennsylvania corporation and a wholly-owned subsidiary of New Mylan (“Merger Sub”), and Abbott Laboratories, an Illinois corporation (“Abbott”). The BTA provides for the acquisition by Mylan of Abbott’s non-U.S. developed markets specialty and branded generics business (the “Assets”) in an all-stock transaction. In the transaction, Abbott will transfer the Assets to New Mylan in consideration for 105,000,000 New Mylan ordinary shares (the “Business Transfer”), and, immediately following the transfer, Merger Sub will merge with and into Mylan, with Mylan surviving the merger and continuing as a wholly-owned subsidiary of New Mylan (the “Merger” and, together with the Business Transfer, collectively, the “Transaction”). At the effective time of the Merger, each issued and outstanding share of Mylan common stock will be converted into the right to receive one New Mylan ordinary share. Mylan shareholders will recognize gain for U.S. federal income tax purposes on the exchange of Mylan common shares for New Mylan ordinary shares.

Prior to closing the Transaction, New Mylan will be converted into a public limited company (naamloze vennootschap) and will be renamed “Mylan N.V.”. New Mylan is organized in the Netherlands and will be led by Mylan’s current leadership team and board of directors. New Mylan’s ordinary shares are expected to be listed on the Nasdaq Global Select Market. Following completion of the Transaction, the former shareholders of Mylan will own approximately 79% of the outstanding New Mylan ordinary shares and Abbott will indirectly own approximately 21% of the outstanding New Mylan ordinary shares.

The Transaction has been unanimously approved by the board of directors of both Abbott and Mylan.

The parties have made customary representations and warranties in the BTA and have agreed to customary pre-closing and post-closing covenants. In addition, the BTA provides that the parties will indemnify each other for breaches of these representations, warranties and covenants, subject to certain limitations, and for certain other matters.

Under the BTA, Abbott will agree for a period of two-years to certain non-competition restrictions in the non-U.S. developed markets with respect to pharmaceutical products which contain the same active pharmaceutical ingredient as the acquired products, subject to certain exceptions.

The consummation of the Transaction is subject to the satisfaction of certain customary closing conditions, including regulatory approvals and the approval of the Merger by Mylan’s shareholders. Abbott will not require shareholder approval in connection with the Transaction.

The BTA contains certain customary termination rights, including the right of either party to terminate the agreement if the Transaction is not completed by October 13, 2015, subject to extension for a period of 90 days in the event conditions relating to regulatory approvals have not been satisfied as of that date. Neither party has the right to terminate the BTA in order to engage in an alternative transaction. If the BTA is terminated in certain circumstances, including in the event that certain regulatory approvals are not obtained, approval of Mylan’s shareholders is not obtained or Mylan’s board of directors withdraws its recommendation of the Transaction or

2

approves or recommends an alternative acquisition proposal for Mylan, Mylan will be required, at Abbott’s option, to reimburse Abbot’s costs and expenses incurred in connection with the Transaction (including certain restructuring related taxes), provided that Mylan will not be required to reimburse Abbott for an amount in excess of $100,000,000.

Upon as of the consummation of the Transaction, New Mylan and Abbott will enter into a Shareholder Agreement. The Shareholder Agreement will impose certain restrictions on Abbott, including prohibiting transfers of New Moon ordinary shares to competitors of Mylan and to activist investors as defined in the agreement, as well as to customary standstill limitations so long as Abbott’s ownership interest in New Moon equals or exceeds 5%. Abbott will agree to vote its New Moon ordinary shares, subject to certain exceptions relating to significant corporate transactions, in accordance with the recommendation by New Moon’s board of directors. Abbott also will be entitled to customary demand and piggy-back registration rights.

At the closing of the Transaction, New Mylan, Abbott and certain of their affiliates will enter into ancillary agreements providing for transition services, manufacturing relationships and license arrangements.

Also on July 13, 2014, prior to the execution of the BTA, the board of directors of Mylan approved Amendment No. 6 to Rights Agreement (the “Amendment”), amending the Rights Agreement (“Rights Agreement”) dated as of August 22, 1996, as amended as of November 8, 1999, August 13, 2004, September 8, 2004, December 2, 2004 and December 19, 2005, among Mylan and American Stock Transfer & Trust Company, as rights agent (the “Rights Agent”). The Amendment, among other things, renders the Rights Agreement inapplicable to the Transaction and the BTA. The Amendment remains subject to approval by the Rights Agent.

On July 14, 2014, Mylan and Abbott issued the joint press release attached to this Current Report as Exhibit 99.1.
