Merger Agreement: On April 24, 2017, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Fresenius Kabi AG, a German stock corporation (“Parent”), Quercus Acquisition, Inc., a Louisiana corporation and wholly owned subsidiary of Parent (“Merger Sub”) and, solely for purposes of Article VIII thereof, Fresenius SE & Co. KGaA, a German partnership limited by shares. The Merger Agreement, which has been adopted by the Board of Directors of the Company, provides for the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. Subject to the terms and conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each of the Company’s issued and outstanding shares of common stock, no par value per share (the “Shares”) (other than Shares owned by the Company or by Parent, Merger Sub or any direct or indirect wholly owned subsidiary of the Company or of Parent (other than Merger Sub) immediately prior to the Effective Time), will be converted into the right to receive $34.00 in cash per Share (the “Merger Consideration”), without interest. Completion of the Merger is subject to customary closing conditions, including (1) the approval of the Merger Agreement by the affirmative vote of the holders of at least a majority of all outstanding Shares (the “Shareholder Approval”), (2) there being no judgment or law enjoining or otherwise prohibiting the consummation of the Merger and (3) the expiration of the waiting period applicable to the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The obligation of each of the Company and Parent to consummate the Merger is also conditioned on the other party’s representations and warranties being true and correct (subject to certain materiality exceptions) and the other party having performed in all material respects its obligations under the Merger Agreement. The Merger Agreement contains representations and warranties and covenants of the parties customary for a transaction of this nature. Among other things, Parent has agreed to promptly take all actions necessary to obtain antitrust approval of the Merger, including (i) entering into consent decrees or undertakings with a regulatory authority, (ii) divesting or holding separate any assets or businesses of Parent or the Company, (iii) terminating existing contractual relationships or entering into new contractual relationships, (iv) effecting any other change or restructuring of Parent or the Company and (v) defending through litigation any claim asserted by a regulatory authority that would prevent the closing of the Merger. Until the earlier of the termination of the Merger Agreement and the Effective Time, the Company has agreed to operate its business in the ordinary course of business in all material respects and has agreed to certain other operating covenants and to not take certain specified actions prior to the consummation of the Merger, as set forth more fully in the Merger Agreement. Pursuant to the terms of the Merger Agreement, the Company held a meeting of its shareholders for the purpose of obtaining the Shareholder Approval and the Board recommended that the Company’s shareholders approve the Merger Agreement. On July 19, 2017, the Company's shareholders voted to approve the Merger Agreement providing for the acquisition of Akorn by Fresenius Kabi AG, a subsidiary of Fresenius SE & Co. KGaA (FWB:FRE). The transaction remains subject to regulatory approvals and customary closing conditions, and the companies expect the acquisition will close in the fourth quarter of 2017. Basis of Presentation: The Company’s financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") for interim financial information and accordingly do not include all the information and footnotes required by GAAP for annual financial statements. In the opinion of management, all adjustments of a normal and recurring nature considered necessary for a fair presentation have been included in these financial statements. Operating results for the three and nine month periods ended September 30, 2017 are not necessarily indicative of the results that may be expected for the full year. For further information, refer to the consolidated financial statements and footnotes for the year ended December 31, 2016, included in the Company’s Annual Report on Form 10-K filed on March 1, 2017.
