Item 1.01

Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On October 15, 2019, Alexion Pharmaceuticals, Inc., a Delaware corporation ("Alexion"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with Beagle Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Alexion ("Merger Subsidiary"), and Achillion Pharmaceuticals, Inc., a Delaware corporation ("Achillion"), pursuant to which, among other things, upon the terms and subject to the conditions thereof, Merger Subsidiary will merge with and into Achillion, with Achillion surviving as a wholly owned subsidiary of Alexion (the "Merger"). The board of directors of Achillion has approved the Merger Agreement and agreed to recommend that Achillion's stockholders adopt the Merger Agreement.

In the Merger, each share of Achillion common stock (a "Share") issued and outstanding immediately prior to the effective time (the "Effective Time") of the Merger (other than certain excluded shares as described in the Merger Agreement) will automatically be converted into the right to receive (1) $6.30 in cash, without interest (the "Cash Merger Consideration"), and (2) one contractual contingent value right pursuant to the CVR Agreement (as defined and described below, a "CVR").

Completion of the Merger is subject to various closing customary conditions, including the adoption of the Merger Agreement by a majority of the holders of the outstanding Shares; the absence of any order or other action issued by a governmental authority restraining, enjoining or otherwise prohibiting the consummation of the Merger and no law having been adopted that makes consummation of the Merger illegal or otherwise prohibited; the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the approval of the Merger under the antitrust laws of other specified jurisdictions; and the absence of certain instituted, pending or threatened litigation or other proceedings.

The Merger Agreement includes representations, warranties and covenants of the parties customary for a transaction of this nature. Among other things, until the earlier of the termination of the Merger Agreement or the Effective Time, Achillion has agreed to operate its business in the ordinary course consistent with past practice and has agreed to certain other operating covenants, as set forth fully in the Merger Agreement. The Merger Agreement also prohibits Achillion's solicitation of proposals relating to alternative transactions and restricts Achillion's ability to furnish information to, or participate in any discussions or negotiations with, any third party with respect to any such transaction, subject to certain limited exceptions.

Either Achillion or Alexion may terminate the Merger Agreement in certain circumstances, including if (1) the Merger is not completed by April 15, 2020, subject to extension by Alexion in certain circumstances in the event that antitrust approval is not obtained (the "End Date"), (2) a governmental authority of competent jurisdiction has issued a final non-appealable order prohibiting the Merger or any applicable law makes consummation of the Merger illegal,

1. Achillion's stockholders fail to adopt the Merger Agreement, (4) the other party breaches its representations, warranties or covenants in the Merger Agreement in a way that would entitle the party seeking to terminate the Merger Agreement not to consummate the Merger, subject to the right of the breaching party to cure the breach, (5) subject to compliance with specified process and notice requirements, Achillion terminates the Merger Agreement in order to enter into an agreement providing for a "Superior Proposal" (as such term is defined in the Merger Agreement), or (6) Achillion's board of directors has changed its recommendation in favor of the Merger. In the event of a termination of the Merger Agreement under certain specified circumstances, including termination by Achillion to enter into an agreement providing for a Superior Proposal, or a termination by Alexion following a change in recommendation by Achillion's board of directors, Achillion may be required to pay Alexion a termination fee equal to $20,000,000. In the event of a termination of the Merger Agreement under certain specified circumstances, including failure to complete the merger by April 15, 2020 (or such later date as extended by Alexion) if, at the time of such termination, any necessary antitrust approval has not been obtained, or a final non-appealable order prohibiting the Merger by a governmental authority of competent jurisdiction, Alexion may be required to pay Achillion a termination fee equal to (i) $30,000,000 if the Merger Agreement is terminated prior to April 15, 2020, (ii) $40,000,000 if Alexion has extended the End Date and the Merger Agreement is terminated after April 15, 2020 but on or prior to the July 15, 2020, (iii) $50,000,000 if Alexion has extended the End Date twice and the Merger Agreement is terminated after July 15, 2020 but on or prior to October 15, 2020 or (iv) $60,000,000 if Alexion has extended the End Date three times and the Merger Agreement is terminated after October 15, 2020.

Alexion intends to fund the acquisition of Achillion through cash on hand.

Contingent Value Rights Agreement

At or prior to the Effective Time, Alexion and a rights agent mutually acceptable to Alexion and Achillion will enter into a Contingent Value Rights Agreement in the form attached to the Merger Agreement as Exhibit B (the "CVR Agreement"), which will govern the terms of the CVRs to be received by Achillion's stockholders. The CVRs are not transferable except under certain limited circumstances, will not be evidenced by a certificate or other instrument and will not be registered or listed for trading. The CVRs will not have any voting or dividend rights and will not represent any equity or ownership interest in Alexion, Merger Subsidiary, Achillion or any of their affiliates.

Each CVR represents the right to receive (1) $1.00 upon the achievement of a Clinical Trial Milestone (as defined in the CVR Agreement) relating to the development of Achillion's product candidate ACH-5528 prior to the fourth anniversary of the consummation of the Merger and (2) $1.00 upon Alexion's first receipt of approval by the FDA of a new drug application or other regulatory approval application which approval grants Alexion the right to market and sell Achillion's product candidate ACH-4471 in the United States prior to the date that is fifty-four months after the date of the consummation of the Merger.

Additional Information

The foregoing description of the Merger Agreement and the CVR Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, which is attached as Exhibit 2.1 to this report, and the Form of CVR Agreement, which is attached as Exhibit B to the Merger Agreement, all of which are incorporated herein by reference.

The Merger Agreement and the CVR Agreement and the foregoing description have been included to provide investors with information regarding the terms of these agreements. They are not intended to provide any other factual information about Alexion or Achillion. The representations, warranties and covenants contained in each of these documents were or will be made only as of specified dates for the purposes of such agreement, were (except as expressly set forth therein) solely for the benefit of the parties to such agreements, and may be subject to qualifications and limitations agreed upon by such parties. In particular, in reviewing the representations, warranties and covenants contained in the Merger Agreement and discussed in the foregoing descriptions, it is important to bear in mind that such representations, warranties and covenants were negotiated with the principal purpose of allocating risk between the parties, rather than establishing matters as facts. Such representations, warranties and covenants may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and reports and documents filed with the U.S. Securities and Exchange Commission (the "SEC"). Investors should not rely on such representations, warranties and covenants as characterizations of the actual state of facts or circumstances described therein. Information concerning the subject matter of such representations, warranties and covenants may change after the date of the agreements, which subsequent information may or may not be fully reflected in the parties' public disclosures.

Forward Looking Statements

The information contained in this Current Report on Form8-K (the "Current Report") is as of October 16, 2019. Alexion assumes no obligation to update forward-looking statements contained in this Current Report as the result of new information or future events or developments.

This Current Report contains forward-looking information related to Alexion, Achillion and the proposed acquisition of Achillion by Alexion that involves substantial risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. Forward-looking statements in this document and the accompanying exhibits include, among other things, statements about the potential benefits of the proposed acquisition, the anticipated CVR payment, earnings dilution and accretion, and growth, Alexion's and Achillion's plans, objectives, expectations and intentions, the financial condition, results of operations and business of Alexion and Achillion, Achillion's product pipeline and portfolio assets, Achillion's ability to achieve certain milestones that trigger the CVR payment and the anticipated timing of closing of the proposed acquisition. Risks and uncertainties include, among other things, risks related to the fact that the proposed acquisition may not be completed due to Alexion's or Achillion's failure to satisfy or waive of the conditions to closing the proposed acquisition (including the failure to obtain necessary regulatory approvals) in the anticipated timeframe or at all, including uncertainties as to whether Achillion's stockholders will approve the Merger and the possibility that the acquisition does not close; the possibility that competing offers may be made; risks related to obtaining the requisite consents to the acquisition, including, without limitation, the timing (including possible delays) and receipt of regulatory approvals from various governmental entities (including any conditions, limitations or restrictions placed on these approvals and the risk that one or more governmental entities may deny approval); the risk that the businesses will not be integrated successfully; disruption from the transaction making it more difficult to maintain business and operational relationships; negative effects of the announcement or the consummation of the proposed acquisition on the market price of Alexion's common stock, Alexion's credit ratings and/or Alexion's operating results; significant transaction costs or unexpected expenses; unknown liabilities; the risk of litigation and/or regulatory actions related to the proposed acquisition; other business effects, including the effects of industry, market, economic, political or regulatory conditions; future exchange and interest rates; changes in tax and other laws, regulations, rates and policies, including government-mandated price decreases of Alexion's products; future business combinations or disposals; the uncertainties inherent in research and development, including the ability to meet anticipated clinical endpoints, commencement and/or completion dates for clinical trials, regulatory submission dates, regulatory

approval dates and/or launch dates, as well as the possibility of unfavorable new clinical data and further analyses of existing clinical data; the potential benefits of factor D inhibition as a treatment for complement-mediated diseases, including danicopan (ACH-4471) for paroxysmal nocturnal hemoglobinuria and C3glomerulopathy (C3G); the potential benefits of, and indications for, Achillion's compounds that inhibit factor D, including danicopan and ACH-5228; the status of enrollment in Achillion's ongoing clinical trials; Achillion's expectations regarding the advancement of, and timeline for reporting results from, clinical trials of its product candidates (including danicopan and ACH-5228) as well as its ability to advance additional compounds; the possibility that results of clinical trials are not predictive of safety and efficacy results of products in broader patient populations; the possibility that clinical trials of product candidates could be delayed or terminated prior to completion for a number of reasons; the possibility that interim results from a clinical trial are not predictive of the final results of that trial and the possibility that results of early clinical trials or preclinical studies will not be indicative of the results of later clinical trials; Achillion's expectations regarding the timing of regulatory interactions and filings; the uncertainty that the milestones for the CVR payment may not be achieved in the prescribed timeframe or at all; the risk that clinical trial data are subject to differing interpretations and assessments by regulatory authorities; whether regulatory authorities will be satisfied with the design of and results from Alexion's and Achillion's clinical studies; the possibility that Achillion fails to satisfactorily address matters raised by the regulatory agencies; whether and when drug applications may be filed in any jurisdictions for any potential indication for any of Alexion's or Achillion's pipeline assets; whether and when any such applications may be approved by regulatory authorities, which will depend on myriad factors, including making a determination as to whether the product's benefits outweigh its known risks and determination of the product's efficacy and, if approved, whether any such products will be commercially successful; decisions by regulatory authorities impacting labeling, manufacturing processes, safety and/or other matters that could affect the availability or commercial potential of any such products; and competitive developments.

A further description of risks and uncertainties relating to Alexion can be found in Alexion's Annual Report on Form10-K for the fiscal year ended December 31, 2018, and in its subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all of which are filed with the SEC and available at www.sec.gov and http://www.alexion.com.

A further description of risks and uncertainties relating to Achillion can be found in Achillion's Annual Report on Form10-K for the fiscal year ended December 31, 2018, and in its subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all of which are filed with the SEC and available at www.sec.gov and http://www.achillion.com.

These forward-looking statements are based on numerous assumptions and assessments made by Alexion and Achillion in light of their respective experiences and perceptions of historical trends, current conditions, business strategies, operating environment, future developments and other factors they believe are appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. The factors described in the context of such forward-looking statements could cause Alexion's plans with respect to Achillion, actual results, performance or achievements, industry results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although it is believed that the expectations reflected in the forward-looking statements in this Current Report are reasonable, no assurance can be given that such expectations will prove to have been correct and persons reading this Current Report are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as at the date hereof.
