Table of Contents

             
             
            If you were a stockholder of record on April 29, 2011, you are entitled to vote all of the shares that you held on that date at the annual meeting and at any postponements or adjournments thereof.

  What are the voting rights of the holders of common stock?   A.   Each outstanding share of our common stock will be entitled to one vote on each matter considered at the annual meeting.
             
Q.
  How do I vote?   A.   If your shares are registered directly in your name, you may vote:
             
           
(1)  Over the Internet:  Go to the website of our tabulator, Computershare Trust Company, N.A., at www.investorvote.com/ALNY. Use the vote control number printed on your enclosed proxy card to access your account and vote your shares. You must specify how you want your shares voted or your Internet vote cannot be completed and you will receive an error message. Your shares will be voted according to your instructions. You must submit your Internet proxy before 11:59 p.m., Eastern Time, on June 8, 2011, the day before the annual meeting, for your proxy to be valid and your vote to count.
             
           
(2)  By Telephone:  Call 1-800-652-VOTE (8683), toll free from the United States, Canada and Puerto Rico, and follow the recorded instructions. You must specify how you want your shares voted and confirm your vote at the end of the call or your telephone vote cannot be completed. Your shares will be voted according to your instructions. You must submit your telephonic proxy before 11:59 p.m., Eastern Time, on June 8, 2011, the day before the annual meeting, for your proxy to be valid and your vote to count.
             
           
(3)  By Mail:  Complete and sign your enclosed proxy card and mail it in the enclosed postage prepaid envelope to Computershare. Computershare must receive the proxy card not later than June 8, 2011, the day before the annual meeting, for your proxy to be valid and your vote to count. Your shares will be voted according to your instructions. If you do not specify how you want your shares voted, they will be voted as recommended by our board.
             
           
(4)  In Person at the Meeting:  If you attend the annual meeting, you may deliver your completed proxy card in person or you may vote by completing a ballot, which we will provide to you at the meeting.
             
            If your shares are held in “street name,” meaning they are held for your account by a broker or other nominee, you may vote:
             
           
(1)  Over the Internet or by Telephone:  You will receive instructions from your broker or other nominee if they permit Internet or telephone voting. You should follow those instructions.
             
           
(2)  By Mail:  You will receive instructions from your broker or other nominee explaining how you can vote your shares by mail. You should follow those instructions.
             
           
(3)  In Person at the Meeting:  Contact your broker or other nominee who holds your shares to obtain a broker’s proxy card and bring it with you to the annual meeting. A broker’s proxy is not the form of proxy enclosed with this proxy statement. You will not be able to vote shares you hold in “street name” in person at the annual meeting unless you have a proxy from your broker issued in your name giving you the right to vote your shares.

Q.
  Can I change my vote?   A.   If your shares are registered directly in your name, you may revoke your proxy and change your vote at any time before the annual meeting. To do so, you must do one of the following:
             
           
(1)  Vote over the Internet or by telephone as instructed above. Only your latest Internet or telephone vote is counted. You may not change your vote over the Internet or by telephone after 11:59 p.m., Eastern Time, on June 8, 2011.
             
           
(2)  Sign a new proxy and submit it as instructed above. Only your latest dated proxy will be counted.
             
           
(3)  Attend the annual meeting, request that your proxy be revoked and vote in person as instructed above. Attending the annual meeting will not revoke your Internet vote, telephone vote or proxy, as the case may be, unless you specifically request it.
             
            If your shares are held in “street name,” you may submit new voting instructions by contacting your broker, bank or nominee. You may also vote in person at the annual meeting if you obtain a broker’s proxy as described in the answer above.
             
Q.
  Will my shares be voted if I do not return my proxy?   A.   If your shares are registered directly in your name, your shares will not be voted if you do not vote over the Internet, by telephone, by returning your proxy or by ballot at the annual meeting.
             
            If your shares are held in “street name,” your brokerage firm may under certain circumstances vote your shares if you do not return your proxy. Brokerage firms can vote customers’ unvoted shares on routine matters. If you do not return a proxy to your brokerage firm to vote your shares, your brokerage firm may, on routine matters, either vote your shares or leave your shares unvoted. Your brokerage firm cannot vote your shares on any matter that is not considered routine.
             
            Proposal 1, election of directors, Proposal 2, advisory “say-on-pay” vote, and Proposal 3, advisory “say-on-frequency” vote, are not considered routine matters. Proposal 4, ratification of the appointment of our independent auditors, is considered a routine matter. We encourage you to provide voting instructions to your brokerage firm or other nominee by giving your proxy to them. This ensures that your shares will be voted at the annual meeting according to your instructions. You should receive directions from your brokerage firm about how to submit your proxy to them at the time you receive this proxy statement.
             
Q.
  How many shares must be present to hold the annual meeting?   A.   A majority of our outstanding shares of common stock must be present to hold the annual meeting and conduct business. This is called a quorum. For purposes of determining whether a quorum exists, we count as present any shares that are voted over the Internet, by telephone, by completing and submitting a proxy or that are represented in person at the meeting. Further, for purposes of establishing a quorum, we will count as present shares that a stockholder holds even if the stockholder votes to abstain or only votes on one of the proposals. In addition, we will count as present shares held in “street name” by brokers or nominees who indicate on their proxies that they do not have authority to vote those shares on Proposals 1, 2 and 3. If a quorum is not present, we expect to adjourn the annual meeting until we obtain a quorum.

Table of Contents

             
             
Q.
  What vote is required to approve each matter and how are votes counted?   A.  
Proposal 1 — Election of Three Class I Directors

The three nominees for director to receive the highest number of votes FOR election will be elected as directors. This is called a plurality. Proposal 1 is not considered a routine matter. Therefore, if your shares are held by your broker in “street name” and you do not vote your shares, your broker cannot vote your shares on Proposal 1. Shares held in “street name” by brokers or nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 1 will not be counted as votes FOR or WITHHELD from any nominee. As a result, “broker non-votes” will have no effect on the voting on Proposal 1. With respect to Proposal 1, you may:
             
           
•   vote FOR all nominees;
             
           
•   vote FOR one or more nominee(s) and WITHHOLD your vote from the other nominee(s); or
             
           
•   WITHHOLD your vote from all nominees.
             
            Votes that are withheld will not be included in the vote tally for the election of directors and will not affect the results of the vote.
             
           
Proposal 2 — Non-binding “Say-on-Pay” Vote on the Compensation of Our Named Executive Officers

To approve Proposal 2, stockholders holding a majority of the votes cast on the matter must vote FOR the approval of the compensation of our named executive officers, as described in the “Compensation Discussion and Analysis,” executive compensation tables and accompanying narrative disclosures in this proxy statement. Proposal 2 is not considered a routine matter. Therefore, if your shares are held by your broker in “street name” and you do not vote your shares, your broker cannot vote your shares on Proposal 2. Shares held in “street name” by brokers or nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 2 will not be counted as votes FOR or ABSTAIN from the proposal. As a result, “broker non-votes” will have no effect on the voting on Proposal 2. With respect to Proposal 2, you may:
             
           
•   vote FOR the non-binding resolution;
             
           
•   vote AGAINST the non-binding resolution; or
             
           
•   ABSTAIN from voting on the non-binding resolution.
             
            As an advisory vote, this proposal is not binding. The outcome of this advisory vote will not overrule any decision by us or our board of directors (or any committee thereof). However, our compensation committee and our board of directors value the opinions expressed by our stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our named executive officers.
             
           
Proposal 3 — Non-binding “Say-on-Frequency” Vote to Recommend Whether Future “Say-on-Pay” Votes Should Occur Every One, Two or Three Years

To recommend the frequency of future non-binding stockholder “Say-on-Pay” votes, you may:
             
           
•   vote CHOICE 1 (every year);
             
           
•   vote CHOICE 2 (every two years);

4


Table of Contents

             
             
           
•   vote CHOICE 3 (every three years); or
             
           
•   ABSTAIN from voting on the non-binding resolution.
             
           
The frequency choice that receives the highest number of votes cast will be considered to be the preferred frequency of our stockholders with which we are to hold future non-binding stockholder advisory “say-on-pay” votes on executive compensation. Proposal 3 is not considered a routine matter. Therefore, if your shares are held by your broker in “street name” and you do not vote your shares, your broker cannot vote your shares on Proposal 3. Shares held in “street name” by brokers or nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 3 will not be counted as votes for any of the frequency choices or an abstention from the proposal. As a result, “broker non-votes” will have no effect on the voting on Proposal 3.

Our board of directors will take into consideration the outcome of this vote in determining the frequency of future executive compensation advisory votes. However, because this vote is advisory and non-binding, our board of directors may decide that it is in our best interests and those of our stockholders to hold the advisory vote to approve executive compensation more or less frequently.
             
            Proposal 4 — Ratification of Appointment of Independent Auditors
             
            To approve Proposal 4, stockholders holding a majority of the votes cast on the matter must vote FOR the proposal. Proposal 4 is considered a routine matter. If your shares are held by your broker in “street name” and you do not vote your shares, your brokerage firm may vote your unvoted shares on Proposal 4. If you vote to ABSTAIN on Proposal 4, your shares will not be voted FOR or AGAINST the proposal and will also not be counted as votes cast or shares voting on the proposal. As a result, voting to ABSTAIN will have no effect on the voting on Proposal 4.
             
            Although stockholder approval of our audit committee’s appointment of PricewaterhouseCoopers LLP as our independent auditors for the year ended December 31, 2011 is not required, we believe that it is advisable to give stockholders an opportunity to ratify this appointment. If this proposal is not approved at the annual meeting, our audit committee will reconsider its appointment of PricewaterhouseCoopers LLP as our independent auditors for the year ended December 31, 2011.
             
Q.
  Are there other matters to be voted on at the annual meeting?   A.   We do not know of any matters that may come before the annual meeting other than the election of three Class I directors, the advisory “say-on-pay” and “say-on-frequency” votes, and the ratification of the appointment of our independent auditors. If any other matters are properly presented at the annual meeting, the persons named in the accompanying proxy intend to vote, or otherwise act, in accordance with their judgment on the matter.
             
Q.
  Where can I find the voting results?   A.   We will report the voting results in a Current Report on Form 8-K within four business days following the adjournment of our annual meeting.

Q.
  What are the costs of soliciting these proxies?   A.   We will bear the cost of soliciting proxies. In addition to these proxy materials, our directors, officers and employees may solicit proxies by telephone, e-mail, facsimile and in person, without additional compensation. We have also retained Alliance Advisors to solicit proxies by mail, courier, telephone and facsimile and to request brokers, custodians and fiduciaries to forward proxy soliciting materials to the owners of stock held in their names. For these services, we have paid a fee of $6,500, plus expenses. We may reimburse brokers or persons holding stock in their names, or in the names of their nominees, for their expenses in sending proxies and proxy material to beneficial owners.
             
Q:
  How do I vote my
401(k) shares?
  A.   You may give voting instructions for the number of shares of Alnylam common stock equal to the interest in Alnylam common stock credited to your 401(k) plan account as of the record date. To vote these shares, complete and return to Computershare the proxy card sent to you with this proxy statement. The 401(k) plan trustee will vote your shares according to your instructions. Only Computershare and its affiliates or agents will have access to your individual voting instructions. You may revoke previously given voting instructions by filing with the trustee either a written revocation or a properly completed and signed proxy bearing a later date. To vote your 401(k) plan shares, you must provide your voting instructions to Computershare before 11:59 p.m., Eastern Time, on June 7, 2011, for your proxy to be valid and your vote to count. If you do not provide voting instructions to the 401(k) plan trustee, the 401(k) plan trustee will not vote your shares.
 
Householding of Annual Meeting Materials
 
Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of our proxy statement and annual report to stockholders may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of either document to you upon written or oral request to Alnylam Pharmaceuticals, Inc., 300 Third Street, Cambridge, Massachusetts 02142, Attention: Investor Relations and Corporate Communications, telephone: (617) 551-8200. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.

Based solely on a review of our records and written representations by the persons required to file these reports, we believe that all filing requirements of Section 16(a) were satisfied with respect to 2010.
 
PROPOSAL 1 — ELECTION OF CLASS I DIRECTORS
 
We have three classes of directors, Class I, Class II and Class III, and the board has set the number of directors at nine. At each annual meeting, directors are elected for a term of three years to succeed those whose terms are expiring. The directors are divided as equally as possible among the three classes and the terms of the three classes are staggered so that only one class is elected by stockholders annually. We currently have a vacancy on our board of directors as a result of the retirement of Vicki L. Sato, Ph.D. effective as of April 30, 2011. Dr. Sato served as a Class II director. We intend to fill this vacancy by a vote of the majority of our remaining directors, which is expected to occur after the 2011 annual meeting, pursuant to our amended and restated bylaws.
 
John M. Maraganore, Ph.D., Paul R. Schimmel, Ph.D. and Phillip A. Sharp, Ph.D. are currently serving as Class I directors. Each of Drs. Maraganore, Schimmel and Sharp has served as a director since 2002. The Class I directors elected this year will serve as members of our board until the 2014 annual meeting of stockholders, or until their respective successors are elected and qualified.
 
The persons named in the enclosed proxy will vote to elect Drs. Maraganore, Schimmel and Sharp as Class I directors unless the proxy is marked otherwise. Drs. Maraganore, Schimmel and Sharp have indicated their willingness to serve on our board, if elected; however, if any nominee should be unable to serve, the person acting under the proxy may vote the proxy for a substitute nominee designated by our board. Our board has no reason to believe that Drs. Maraganore, Schimmel or Sharp would be unable to serve if elected.

CORPORATE GOVERNANCE
 
General
 
We believe that good corporate governance is important to ensure that Alnylam is managed for the long-term benefit of our stockholders. This section describes key corporate governance practices that we have adopted.
 
We have adopted a Code of Business Conduct and Ethics, which applies to all of our officers, directors and employees, as well as charters for our audit committee, our compensation committee and our nominating and corporate governance committee, and corporate governance guidelines. We have posted copies of these documents on the Corporate Governance page of the Investors section of our website, www.alnylam.com. We intend to disclose on our website any amendments to, or waivers from, our Code of Business Conduct and Ethics required to be disclosed by law or NASDAQ Global Market listing standards.

Corporate Governance Guidelines
 
Our board of directors has adopted corporate governance guidelines to assist in the exercise of its duties and responsibilities and to serve the best interests of Alnylam and our stockholders. These guidelines, which provide a framework for the conduct of our board of directors’ business, provide that:
 
  •  our board’s principal responsibility is to oversee the management of Alnylam;
 
  •  a majority of the members of our board shall be independent directors;
 
  •  the independent directors meet regularly in executive session;
 
  •  directors have full and free access to management and, as necessary and appropriate, independent advisors; and
 
  •  periodically, our board and its committees will conduct a self-evaluation to determine whether they are functioning effectively.
 
We have posted a copy of our corporate governance guidelines on the Corporate Governance page of the Investors section of our website, www.alnylam.com.
 
Board Determination of Independence
 
Under the NASDAQ Marketplace Rules, a director only will qualify as an “independent director” if, in the opinion of our board, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Our board has determined that none of Ms. Fannuci, Drs. Dzau, Paul, Sato and Schimmel and Messrs. Clarke and Starr have a relationship which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is an “independent director” as defined under NASDAQ Rule 5605(a)(2). In making such determination, our board considered relationships, if any, that each non-employee director has with Alnylam, their beneficial ownership of our outstanding common stock and all other facts and circumstances our board deemed relevant in determining their independence.
 
Role of the Board
 
Our board of directors is responsible for establishing broad corporate policies and reviewing our overall performance rather than day-to-day operations. The primary responsibility of our board is to oversee the management of our company and, in doing so, serve the best interests of the company and our stockholders. Our board selects, evaluates and provides for the succession of executive officers and, subject to stockholder election, directors. It reviews and approves corporate objectives and strategies, and evaluates significant policies and proposed major commitments of corporate resources. Our board also participates in decisions that have a potential major economic impact on our company. Management keeps our directors informed of company activity through regular communication, including written reports and presentations at board of directors and committee meetings.
 
Board Leadership Structure
 
Our board has determined that the roles of chief executive officer and chairman of the board should be separated at the current time. Mr. Clarke, an independent director, has served as our chairman since the founding of Alnylam in 2002, and Dr. Maraganore has served as our chief executive officer and a director since 2002. Separating these positions allows our chief executive officer to focus on our day-to-day business operations, while allowing the chairman to lead the board in its fundamental role of providing advice to and independent oversight of management. The board recognizes the time, effort and energy that the chief executive officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our chairman, particularly as the board’s oversight responsibilities continue to grow. While our bylaws and corporate governance guidelines do not require that our chairman and chief executive officer positions be separate, our board believes that our current leadership structure is appropriate

because it provides an effective balance between strategy development and independent leadership and management oversight.
 
The Board’s Role in Risk Oversight
 
We face a number of risks in our business, including risks related to: pre-clinical and clinical research and development; regulatory reviews, approvals and oversight; intellectual property filings, prosecution, maintenance and challenges; the establishment and maintenance of strategic alliances; competition; and the ability to access additional funding for our business; as well as other risks. Our management is responsible for the day-to-day management of the risks that we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management.
 
Our board administers its risk oversight function directly and through its three committees. Our chairman meets regularly with our chief executive officer and other executive officers to discuss strategy and risks facing the company. Members of senior management attend the quarterly board meetings and are available to address any questions or concerns raised by the board on risk management-related and any other matters. Each quarter, the board of directors receives presentations from members of senior management on strategic matters involving our business. In addition, as part of its charter, the audit committee regularly discusses with management our risk exposures in the areas of financial reporting, internal controls and compliance with legal and financial regulatory requirements, their potential impact on our company and the steps we take to manage them. The compensation committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks arising from our compensation policies and programs. The nominating and governance committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks associated with board organization, membership and structure, succession planning for our directors and executive officers, and corporate governance.
 
Board of Directors Meetings and Attendance
 
Our board met five times during 2010, either in person or by teleconference. During 2010, each of our directors attended at least 75% of the aggregate number of board meetings and meetings of the committees on which he or she then served.
 
Our directors are expected to attend the annual meeting of stockholders. All of our directors attended the 2010 annual meeting of stockholders. We expect substantially all of our directors to attend the 2011 annual meeting.
 
Board Committees
 
Our board of directors has established three standing committees — audit, compensation, and nominating and corporate governance — each of which operates under a written charter that has been approved by our board. We have posted copies of each committee’s charter on the Corporate Governance page of the Investors section of our website, www.alnylam.com. The members of each committee are appointed by our board, upon recommendation of our nominating and corporate governance committee.
 
Our board has determined that all of the members of each of its three standing committees are independent as defined under the NASDAQ Marketplace rules, and, in the case of all members of our audit committee, the independence requirements of Rule 10A-3 under the Exchange Act.
 
Audit Committee
 
Our audit committee is responsible for:
 
  •  appointing, evaluating, retaining, approving the compensation of and, when necessary, terminating the engagement of our independent auditors;
 
  •  taking appropriate action, or recommending that our board of directors take appropriate action, to oversee the independence of our independent auditors;

Table of Contents

 
  •  reviewing and discussing with management and the independent auditors our annual and quarterly financial statements and related disclosures;
 
  •  monitoring our internal control over financial reporting, disclosure controls and procedures, and Code of Business Conduct and Ethics;
 
  •  reviewing and discussing our financial risk management policies;
 
  •  establishing policies regarding hiring employees from our independent auditors and procedures for the receipt and retention of accounting related complaints and concerns;
 
  •  meeting independently with our independent auditors and management; and
 
  •  preparing the audit committee report required by SEC rules, which is included below under the heading “Report of the Audit Committee.”
 
In addition, our audit committee must approve or ratify any related party transaction entered into by us. Our policies and procedures for the review and approval of related person transactions are summarized under the heading “Policies and Procedures for Related Person Transactions,” which appears below.
 
The members of our audit committee are Messrs. Starr (Chair) and Clarke and Ms. Fanucci. Through April 1, 2011, the members of our audit committee were Messrs. Starr (Chair) and Clarke and Dr. Schimmel. We believe that each member of our audit committee satisfies the requirements for membership, including independence, established by NASDAQ and the SEC. Our board has determined that Mr. Starr is an “audit committee financial expert” as defined in Item 407(d)(5) of Regulation S-K. No member of our audit committee is the beneficial owner of more than 10% of our common stock.
 
Our audit committee met four times during 2010, either in person or by teleconference.
 
Compensation Committee
 
Our compensation committee is responsible for:
 
  •  annually reviewing and approving corporate goals and objectives relevant to compensation of our executive officers;
 
  •  reviewing and approving, or making recommendations to our board with respect to, the compensation of our chief executive officer and other executive officers;
 
  •  overseeing an evaluation of our senior executives;
 
  •  overseeing and administering our stock-based compensation plans and 401(k) plan, and performing the duties imposed on the compensation committee by the terms of those plans;
 
  •  reviewing and making recommendations to our board with respect to director compensation;
 
  •  reviewing, and amending as necessary, our compensation philosophy and objectives;
 
  •  reviewing and discussing annually with management our “Compensation Discussion and Analysis,” which is included beginning on page 23 of this proxy statement; and
 
  •  preparing the compensation committee report required by SEC rules, which is included immediately following the “Compensation Discussion and Analysis” section appearing below.
 
Our compensation committee has retained Towers Watson, an independent, nationally recognized compensation consultant, to provide assistance from time to time in reviewing the compensation paid to our senior management team, which is comprised of our named executive officers and all of our vice presidents, and our non-employee directors, and to review our compensation programs and practices generally. In 2010, our compensation committee engaged Towers Watson to assist it in: assessing competitive compensation levels and pay mix (base salary, target annual incentive award and long-term incentive compensation) for our senior management team based upon comparison with our peer group, which peer group is described below under the heading “Compensation Discussion and Analysis,” and market survey data; and reviewing equity utilization

and annual stock option awards as compared to our peer group. In connection with its work for the compensation committee during 2010, Towers Watson prepared reports for the compensation committee, met with the Chair of the committee as necessary and attended certain committee meetings to present its findings and recommendations.
 
The processes and procedures followed by our compensation committee in considering and determining executive compensation is described below under the heading “Compensation Discussion and Analysis.”
 
The members of our compensation committee are Drs. Paul (Chair) and Schimmel and Mr. Starr. Through April 1, 2011, the members of our compensation committee were Drs. Sato (Chair) and Paul and Mr. Starr. We believe that each member of our compensation committee satisfies the requirements for membership, including independence, as established by NASDAQ.
 
Our compensation committee met six times during 2010, either in person or by teleconference, and acted by written consent seven times.
 
Nominating and Corporate Governance Committee
 
Our nominating and corporate governance committee is responsible for:
 
  •  identifying individuals qualified to become members of our board;
 
  •  recommending to our board the persons to be nominated for election as directors and the persons to be appointed to each of our board committees;
 
  •  reviewing and making recommendations to our board with respect to management succession planning;
 
  •  developing and recommending to our board a set of corporate governance principles; and
 
  •  overseeing the evaluation of our board.
 
The processes and procedures followed by our nominating and corporate governance committee in identifying and evaluating director candidates are described below under the heading “Director Nomination Process.”
 
The members of our nominating and corporate governance committee are Mr. Clarke (Chair) and Dr. Dzau. We believe that each member of our nominating and corporate governance committee satisfies the requirements for membership, including independence, as established by NASDAQ.
 
Our nominating and corporate governance committee met five times during 2010, either in person or by teleconference.
 
Director Nomination Process
 
Our nominating and corporate governance committee is responsible for identifying individuals qualified to become directors, consistent with criteria approved by our board, and recommending the persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate.
 
The process followed by our nominating and corporate governance committee to identify and evaluate director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the committee and our board.
 
Criteria and Diversity
 
Our corporate governance guidelines specify that diversity on the board should be considered by the nominating and corporate governance committee in the director identification and nomination process. In considering whether to recommend any particular candidate for inclusion in our board’s slate of recommended director nominees, our nominating and corporate governance committee will apply certain criteria, including


18


Table of Contents

the candidate’s integrity, business acumen, knowledge of our business and industry, experience, diligence, conflicts of interest and ability to act in the interests of all stockholders. Our nominating and corporate governance committee also considers issues of diversity, such as diversity of gender, race and national origin, education, professional experience and differences in viewpoints and skills. While our nominating and corporate governance committee does not have a formal policy with respect to diversity, our board and nominating and corporate governance committee believe that it is essential that the board members represent diverse viewpoints. The committee does not assign specific weights to particular criteria and no particular criterion is a prerequisite for each prospective nominee. We believe that the backgrounds and qualifications of our directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow our board to promote our strategic objectives and fulfill its responsibilities to our stockholders.
 
The director biographies appearing above under “Proposal 1 — Election of Class I Directors” indicate each nominee’s experience, qualifications, attributes and skills that led our board to conclude that he should continue to serve as a member of our board. Our board believes that each of the nominees has had substantial achievement in his professional and personal pursuits, and possesses the background, talents and experience that our board desires and that will contribute to the best interests of our company and to long-term stockholder value.
 
Stockholder Nominations
 
Stockholders may recommend individuals to our nominating and corporate governance committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials and, if the stockholder is not a stockholder of record, a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more than 5% of our common stock for at least a year as of the date such recommendation is made, to the nominating and corporate governance committee, c/o Corporate Secretary, Alnylam Pharmaceuticals, Inc., 300 Third Street, Cambridge, Massachusetts 02142. Assuming that appropriate biographical and background material has been provided on a timely basis, the committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others. Stockholders also have the right under our bylaws to nominate director candidates directly, without any action or recommendation on the part of the committee or the board, by following the procedures set forth below under the heading “Stockholder Proposals.”
 
At the annual meeting, stockholders will be asked to consider the election of Drs. Maraganore, Schimmel and Sharp, each of whom currently serves on our board of directors. Drs. Maraganore, Schimmel and Sharp were proposed to our board by our nominating and corporate governance committee and our board determined to include them as its nominees.
 
Communicating with the Independent Directors
 
Our board of directors will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. The chair of our board (if an independent director), the lead director (if one is appointed), or otherwise the chair of our nominating and corporate governance committee, is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the other directors as he or she considers appropriate.
 
Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that the chair of our board (if an independent director), or the lead director (if one is appointed), or otherwise the chair of our nominating and corporate governance committee, considers to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive communications.
 
Stockholders who wish to send communications on any topic to our board should address such communications to the Board of Directors, c/o Corporate Secretary, Alnylam Pharmaceuticals, Inc., 300 Third Street, Cambridge, Massachusetts 02142.

Risk Considerations in Executive Compensation
 
Our compensation committee has discussed the concept of risk as it relates to our executive compensation program and our compensation committee does not believe our executive compensation program encourages excessive or inappropriate risk taking. As described more fully below in “Compensation Discussion and Analysis,” we structure our pay to consist of both fixed and variable compensation to motivate our executives to produce superior short- and long-term results that are in the best interests of our company and stockholders in order to attain our ultimate objective of increasing stockholder value. We believe that any risks that may arise from our compensation policies and practices for our employees are not reasonably likely to have a material adverse effect on our company.
 
Report of the Audit Committee
 
Our audit committee reports to and acts on behalf of our board by providing oversight of our financial management, related person transaction policies and procedures, audits of our financial statements and financial reporting controls and accounting policies and procedures. Our management is responsible for the preparation, presentation and integrity of our financial statements, the appropriateness of our accounting principles and reporting policies, and for establishing and maintaining adequate internal control over financial reporting. The independent registered public accounting firm is responsible for conducting an independent audit of our annual financial statements and our internal control over financial reporting. Our audit committee is responsible for independently overseeing the conduct of these activities by our management and our independent registered public accounting firm.
 
Our audit committee operates under a written charter adopted by our board that reflects standards contained in the NASDAQ Marketplace Rules. Our audit committee reviews its charter annually and, in April 2010, recommended to our Board, and our Board approved, certain amendments thereto. A complete copy of the current audit committee charter, as amended, is posted on the Corporate Governance page of the Investors section of our website, www.alnylam.com and is attached to this proxy statement as Appendix A.
 
Our audit committee has reviewed our audited financial statements for the fiscal year ended December 31, 2010, and has discussed them with our management and our independent registered public accounting firm, PricewaterhouseCoopers LLP. Our audit committee has also received from, and discussed with, PricewaterhouseCoopers LLP various communications that PricewaterhouseCoopers LLP is required to provide to our audit committee, including the matters required to be discussed by the Public Company Accounting Oversight Board, or PCAOB, AU Section 380, Communication with Audit Committees, as amended, which requires the independent registered public accounting firm to provide the audit committee with additional information regarding the scope and results of the audit, including the independent registered public accounting firm’s responsibilities under PCAOB standards, significant issues or disagreements concerning our accounting practices or financial statements, significant accounting policies, significant accounting adjustments, alternative accounting treatments, accounting for significant unusual transactions, and estimates, judgments and uncertainties.
 
In addition, PricewaterhouseCoopers LLP provided our audit committee with the written disclosures and the letter required by PCAOB Rule 3526, Communication with Audit Committees Concerning Independence, as amended, and our audit committee and PricewaterhouseCoopers LLP have discussed its independence from us and our management, including the matters in those written disclosures.
 
In this context, our audit committee meets regularly with PricewaterhouseCoopers LLP and our management (including private sessions with each of PricewaterhouseCoopers LLP and members of management) to discuss any matters that our audit committee or these individuals believe should be discussed. Our audit committee conducts a meeting each quarter to review the financial statements prior to the public release of earnings.
 
Based on its discussions with management and PricewaterhouseCoopers LLP, and its review of the representations and information provided by management and PricewaterhouseCoopers LLP, our audit committee recommended to our board that the audited financial statements be included in our Annual Report


20


Table of Contents

on Form 10-K for the year ended December 31, 2010. Our audit committee also recommended to our board, and our board has approved, subject to stockholder ratification, the appointment of PricewaterhouseCoopers LLP as our independent auditors for the fiscal year ending December 31, 2011.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
Policies and Procedures for Related Person Transactions
 
Our board has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which Alnylam is a participant, the amount involved exceeds $120,000, and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of whom we refer to as a “related person,” has a direct or indirect material interest.
 
If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a “related person transaction,” the related person must report the proposed related person transaction to our general counsel. The policy calls for the proposed related person transaction to be reviewed and, if


21


Table of Contents

deemed appropriate, approved by our audit committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, our audit committee will review, and, in its discretion, may ratify the related person transaction. The policy also permits the chair of our audit committee to review and, if deemed appropriate, approve proposed related person transactions that arise between committee meetings, subject to ratification by our audit committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually.
 
A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by our audit committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, our audit committee will review and consider:
 
  •  the related person’s interest in the related person transaction;
 
  •  the approximate dollar value of the amount involved in the related person transaction;
 
  •  the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;
 
  •  whether the transaction was undertaken in the ordinary course of our business;
 
  •  whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;
 
  •  the purpose of, and the potential benefits to us of, the transaction; and
 
  •  any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.
 
Our audit committee may approve or ratify the transaction only if the committee determines that, under all of the circumstances, the transaction is not inconsistent with our best interests. Our audit committee may impose any conditions on the related person transaction that it deems appropriate.
 
In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, our board has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:
 
  •  interests arising solely from the related person’s position as an executive officer of another entity (whether or not the person is also a director of such entity), that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, and (b) the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction; and
 
  •  a transaction that is specifically contemplated by provisions of our charter or bylaws.
 
The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by our compensation committee in the manner specified in its charter.
 
Related Person Transactions
 
Agreements with Novartis
 
Beginning in September 2005, we entered into the first of two strategic alliances with Novartis Pharma AG and its affiliate, Novartis Institutes for Biomedical Research, Inc., whom we refer to together as Novartis. At that time, we and Novartis executed a stock purchase agreement and an investor rights agreement, and ultimately executed a research collaboration and license agreement. The investor rights agreement provides Novartis with the right generally to maintain its ownership percentage in us until the earlier of any sale by Novartis of shares of our common stock and the expiration or termination of the collaboration and license agreement, subject to certain exceptions. Pursuant to the terms of the investor rights agreement, in April

2010, Novartis purchased an additional 55,223 shares of our common stock at a purchase price of $17.99 per share. As of March 31, 2011, Novartis owned approximately 13.2% of our common stock.
 
Severance Arrangement
 
In February 2011, Ms. Allen resigned as our vice president of finance and treasurer. In connection with her resignation, we and Ms. Allen entered into a separation agreement, under which we have agreed to provide Ms. Allen with the following severance pay and benefits in consideration for her agreement to a general release and certain other standard terms and conditions: (i) severance in the gross amount of $250,397 (an amount equal to 12 months of Ms. Allen’s gross base salary); (ii) the full cost of any COBRA premiums until the earlier of March 21, 2012 and the date Ms. Allen becomes eligible for coverage under the group health plan of another employer; (iii) a consulting agreement for a period of up to 12 months following her separation date under which she will perform certain services at our request, the terms of which are described below; and (iv) continued vesting of any unvested stock options held by Ms. Allen during the term of the consulting agreement. In connection with the execution of the separation agreement, we and Ms. Allen also entered into a consulting agreement. Under the consulting agreement, Ms. Allen will provide consulting services to us with respect to general accounting, operating budget, public company financial reporting and treasury-related activities. The consulting agreement has a term of one year and may be terminated by either party in the event of an uncured material breach of its terms by the other party.
 
Other than these transactions, we have not been a participant in any transaction, nor is there any currently proposed transaction, that is reportable under Item 404(a) of Regulation S-K.
 
INFORMATION ABOUT EXECUTIVE OFFICER AND DIRECTOR COMPENSATION
 
Compensation Discussion and Analysis
 
Our compensation committee is responsible for overseeing the total compensation of our senior management team, which is comprised of our named executive officers and all of our vice presidents. In this capacity, our compensation committee designs, implements, reviews and approves all compensation for our chief executive officer and our other named executive officers. The goal of our compensation committee is to ensure that our compensation programs are aligned with the interests of our stockholders and our business goals and that the total compensation paid to each of our named executive officers is fair, reasonable and competitive.
 
Compensation Objectives and Philosophy
 
Our compensation programs are designed to attract, motivate and retain qualified and talented executives, motivating them to achieve our business goals and rewarding them for superior short- and long-term performance. In particular, our compensation programs are intended to reward the achievement of specified pre-determined quantitative and qualitative individual and corporate performance goals and objectives and to align the interests of our senior management team with those of our stockholders in order to attain our ultimate objective of increasing stockholder value.
 
Elements of Total Compensation and Relationship to Performance
 
Key elements of our compensation programs include:
 
  •  base salary;
 
  •  an annual cash incentive program; and
 
  •  equity incentive compensation, which is typically subject to multi-year vesting based on continued service and is primarily in the form of stock options, the value of which depends on the performance of our common stock price.


23


Table of Contents

 
We award annual merit-based increases in base salary based upon an assessment of each executive’s performance and the scope of his or her responsibilities. Consistent with our compensation philosophy, we target salaries between the 50th and 60th percentile of the range of salaries of a group of similarly sized and positioned national and regional companies in the biopharmaceutical and biotechnology industries, which we refer to as our peer group. Our 2010 annual incentive program was designed to reward annual achievements as measured against pre-determined quantitative and qualitative individual and corporate performance goals and objectives, with no further consideration given to the executive’s scope of responsibility, leadership effectiveness, or additional achievements accomplished during the year that were not pre-specified as part of individual or corporate goals. We awarded cash incentive payments to our named executive officers and the other members of our senior management team under our 2010 annual incentive program, which is described in more detail below. In 2011, our named executive officers and the other members of our senior management team will be eligible to receive cash awards under our 2011 annual incentive program. We typically grant stock options to our executive officers upon commencement of their employment, annually following a review of their individual performance and in connection with a promotion. With the exception of our 2010 annual cash incentive program, we do not have any pre-established targets for allocations or apportionment by type of compensation. The mix of compensation components is designed to reward annual results as well as drive long-term company performance and create stockholder value.
 
Determining and Setting Executive Compensation
 
We develop our compensation programs after reviewing publicly available compensation data and subscription survey data for our peer group, as described below.
 
Defining and Comparing Compensation to Market Benchmarks
 
During 2010, our compensation committee engaged Towers Watson for assistance with its review of the compensation of our senior management team. In evaluating the total compensation of our named executive officers, our compensation committee, with the assistance of Towers Watson, established a peer group of 19 publicly traded, national and regional companies in the biopharmaceutical and biotechnology industries that was selected based on a balance of the following criteria:
 
  •  companies whose organizational structure, number of employees, stage of development, market capitalization, research and development expenditures and revenues are similar, though not necessarily identical, to ours;
 
  •  companies with similar executive positions to ours;
 
  •  companies against which we believe we compete for executive talent; and
 
  •  public companies based in the United States whose compensation and financial data are available in proxy statements or other public documents.
 
Based on these criteria, our peer group for 2010, referred to as our 2010 peer group, was comprised of the following:
 
         
Acorda Therapeutics, Inc.   Isis Pharmaceuticals, Inc.   Seattle Genetics, Inc.
Alexion Pharmaceuticals, Inc.   Lexicon Pharmaceuticals, Inc.   Theravance, Inc.
Alkermes, Inc.   Momenta Pharmaceuticals, Inc.   The Medicines Company
Cubist Pharmaceuticals, Inc.   Onyx Pharmaceuticals, Inc.   XenoPort, Inc.
Exelixis, Inc.   PDL BioPharma, Inc.   ZymoGenetics, Inc.
Human Genome Sciences, Inc.   Regeneron Pharmaceuticals, Inc.    
Incyte Corporation   Rigel Pharmaceuticals, Inc.    
 
The peer group for our named executive officers is approved by our compensation committee annually.
 
In order to gain a broader perspective on general industry compensation levels, our compensation committee also considered the total compensation of executives in a broader biotechnology industry group,


24


Table of Contents

which, for 2010, consisted of 54 biotechnology and biopharmaceutical companies listed in the 2010 Radford Global Life Sciences Survey, with a focus on companies with 150 to 499 employees. This larger survey group included 16 of the companies in our 2010 peer group, among other companies. When conducting its review of our executive compensation programs, our compensation committee considered the compensation of our 2010 peer group and the larger survey group described above.
 
We believe that the compensation practices of our 2010 peer group provide us with appropriate compensation benchmarks for evaluating the compensation of our named executive officers. Notwithstanding the similarities of the 2010 peer group to Alnylam, due to the nature of our business, we compete for executive talent with many companies that are larger and more established than we are or that possess greater resources than we do, as well as with prestigious academic and non-profit institutions. Accordingly, in 2010, our compensation committee generally targeted compensation for our executive officers as follows:
 
  •  base salaries between the 50th and 60th percentile of the salaries in our 2010 peer group;
 
  •  annual cash incentive award opportunities at or below the 25th percentile of our 2010 peer group;
 
  •  total annual equity incentive awards at or above the 75th percentile of our peer 2010 group; and
 
  •  total compensation for our executives between the 50th and 75th percentile of compensation paid to similarly situated executives of the companies in our 2010 peer group.
 
Our compensation committee may consider other criteria, including market factors, the experience level of the executive and the executive’s performance against established corporate goals and individual objectives, in determining variations to this general target range.
 
Other Key Factors in Determining Executive Compensation
 
As the biopharmaceutical industry is characterized by a very long product development cycle, including a lengthy research and development period and a rigorous approval phase involving human testing and governmental regulatory approval, many of the traditional benchmarking metrics, such as product sales, revenues and profits are inappropriate for an early-stage biopharmaceutical company, such as Alnylam. Instead, the specific factors our compensation committee considers when determining the compensation of our named executive officers include:
 
  •  key research and development achievements, including advances in RNAi delivery and technology;
 
  •  initiation and progress of clinical trials;
 
  •  achievement of regulatory milestones;
 
  •  establishment and maintenance of key strategic relationships and new business initiatives;
 
  •  filing, prosecution, defense and enforcement of key intellectual property rights;
 
  •  development of organizational capabilities; and
 
  •  financial and operating performance.
 
These factors are considered by our compensation committee in connection with our annual performance reviews described below and are a critical component in the determination of annual cash and equity incentive awards for our executives.
 
Annual Performance Reviews
 
Our compensation committee conducts an annual performance review of each member of our senior management team. During the first quarter of each year, annual corporate goals and individual performance objectives are determined and set forth in writing. At the beginning of the second half of each year, senior management formally reviews performance against goals for the first half of the year and re-aligns key goals for the second half of the year. At the end of each year, our compensation committee determines executive compensation levels after carefully reviewing overall corporate performance and performing a detailed


25


Table of Contents

evaluation of each named executive officer’s annual performance against established corporate goals and individual objectives. In addition, our compensation committee applies its discretion, as it deems appropriate, in determining executive compensation.
 
Annual corporate goals are proposed by our senior management team and approved by our board. Individual objectives for 2010 focused on contributions that are intended to drive achievement of the corporate goals and were proposed by each member of senior management, with review and input from our chief executive officer. Our compensation committee approved the individual objectives for each of our named executive officers and the remaining members of our senior management team. Any increases in base salary, annual stock option awards or cash awards under our annual incentive program were based on the achievement of these corporate and individual performance goals and objectives. In 2010, our compensation committee established the maximum cash bonus opportunity for each member of our senior management team under the 2010 annual incentive program, representing a percentage of each individual’s base salary.
 
During the last quarter of each year, our senior management team evaluates our corporate performance and each officer’s individual performance, as compared to the corporate goals and individual objectives for that year. Based on this evaluation, our chief executive officer recommends to our compensation committee any increases in base salary and any annual stock option awards and/or cash awards under our annual incentive program. Our compensation committee, with input from the chairman of our board, evaluates our chief executive officer’s individual performance and determines whether to change his base salary, grant him an annual stock option award and/or grant him a cash award under our annual incentive program. Our board typically grants annual stock option awards, and determines changes in base salary and the amount of any cash incentive payments, at its last regularly scheduled meeting of the year. The board may also review our chief executive officer’s compensation throughout the course of the year. With respect to year-end reviews, any changes in base salary are effective at the beginning of the following year. The cash incentive payments awarded under our 2010 annual incentive program were paid in January 2011.
 
Base Salary
 
We provide base salaries to our named executive officers to compensate them with a fair and competitive base level of compensation for services rendered during the year. Our compensation committee typically determines the base salary for each executive based on the executive’s responsibilities, experience and, if applicable, the base salary level of the executive prior to joining Alnylam. In addition, our compensation committee reviews and considers the level of base salary paid by companies in our peer group for similar positions. Generally, our compensation committee believes our executives’ base salaries should be targeted between the 50th and 60th percentile of the salaries in our peer group.
 
Merit-based increases in base salary for all of our executives, other than our chief executive officer, are determined by our compensation committee based upon a written summary of the executive’s performance and a recommendation from our chief executive officer. Any merit-based increase in base salary for our chief executive officer is based upon an assessment of his performance by our compensation committee, input from the chairman of our board and a review by our compensation committee of the base salary of chief executive officers in our peer group.
 
With respect to Dr. Maraganore, our chief executive officer, notwithstanding the company’s and Dr. Maraganore’s accomplishments in 2010, as described below, our compensation committee decided to accept the request by Dr. Maraganore that his base salary for 2011 remain at the same level as 2010 for the current time. Dr. Maraganore has elected not to take an increase in his base salary since January 2008.
 
With respect to Mr. Greene, our president and chief operating officer, based on a review of Mr. Greene’s base salary relative to similar positions in our peer group, the compensation committee determined that Mr. Greene’s cash compensation was generally below the target percentile as compared to our peer group. Based on the desire of our compensation committee to provide a competitive base salary between the 50th and 60th percentiles of our 2010 peer group with respect to Mr. Greene, and in light of the company’s and Mr. Greene’s accomplishments in 2010, as described below, our compensation committee approved a base pay market adjustment to better align his annual salary with our compensation philosophy.

*** In February 2011, Ms. Allen resigned from her position as vice president of finance and treasurer.
 
2010 Annual Incentive Program
 
Our compensation committee aims to determine an appropriate mix of cash payments and equity incentive awards to meet short- and long-term goals and objectives. Under the 2010 annual incentive program, specified employees, including our named executive officers and the other members of our senior management team, were eligible to receive an annual cash incentive award based upon the achievement of corporate goals and individual objectives for 2010. The corporate goals for 2010 were proposed by our executive officers and modified and approved by our board. Individual objectives for 2010 were focused on contributions that would drive the achievement of our corporate goals and ensure consistent alignment of the interests of our executive officers and the interests of our stockholders. The compensation committee approved the individual objectives for our named executive officers and the other members of our senior management team. The individual objectives for the other eligible participants were approved by our chief executive officer.
 
Awards under the 2010 annual incentive program were determined by first establishing a participant’s individual performance level, which was based upon a strict and rigid assessment of that individual’s performance against pre-established individual objectives for 2010. Each participant had an established maximum cash award opportunity under the incentive program representing a percentage of the participant’s base salary for 2010. Each participant was eligible to receive an award ranging from 0% to 100% of such participant’s maximum cash award opportunity based upon the participant’s individual performance against his or her 2010 objectives, as described below.
 
A corporate performance modifier was then applied to the individual award. The corporate performance modifier could range from 0% to 100% and was based upon our performance against the 2010 corporate goals approved by our board. The 2010 annual cash incentive program provided that, in the event overall corporate performance for 2010 fell below a threshold of 50%, the corporate performance modifier would be 0% and no awards would be granted under the incentive program.

In determining the 2010 compensation and annual incentive award for each of our executive officers, our compensation committee strictly compared the performance of our company during 2010 and each individual’s performance to his or her individual corporate, financial, strategic and operational objectives for the year.
 
The individual objectives for our chief executive officer, Dr. Maraganore, were heavily weighted toward achievement of the overall company performance rating and certain new business development objectives (50%). In addition, other specific targets included achieving human proof of concept in our clinical programs (25%) and developing certain organizational capabilities (25%). Our compensation committee determined that Dr. Maraganore achieved 40% of his individual objectives for 2010, including advancing our clinical pipeline and continuing to develop and build the organization. Our compensation committee determined that under the

Table of Contents

2010 annual incentive program, Dr. Maraganore earned a cash incentive award of $60,900, representing 40% of his target cash award opportunity, reduced by the corporate performance modifier of 58%.
 
The individual objectives for Mr. Greene included specific targets with respect to advancing our clinical development pipeline and achieving major development program objectives (40%), advancing our delivery platform (30%), aligning our research and development capabilities with alliance management and achieving specific business development goals (20%), and managing and building our research and development organization (10%). Our compensation committee also considered Dr. Maraganore’s recommendations with respect to Mr. Greene’s performance. Our compensation committee determined that Mr. Greene achieved 75% of his individual objectives for 2010, including advancing our clinical pipeline, advancing our delivery platform, and achieving alliance management and certain related business development goals. Our compensation committee determined that under the 2010 annual incentive program, Mr. Greene earned a cash incentive award of $50,895, representing 75% of his target cash award opportunity, reduced by the corporate performance modifier of 58%.
 
Dr. Reid’s individual objectives were focused primarily on achieving specific business development goals (50%), as well as advancing our delivery platform (20%), establishing new business ventures and other potential opportunities (20%), and providing leadership in strategic corporate initiatives (10%). Our compensation committee also considered both Dr. Maraganore’s and Mr. Greene’s recommendations with respect to Dr. Reid’s performance. Our compensation committee determined that Dr. Reid achieved 60% of his individual objectives for 2010, including in particular through the advancement of our delivery efforts and new business ventures. Our compensation committee determined that under the 2010 annual incentive program, Dr. Reid earned a cash incentive award of $13,195, representing 60% of his pro-rated target cash award opportunity, reduced by the corporate performance modifier of 58%.
 
Dr. Koblan’s individual objectives, prior to his promotion to chief scientific officer in September 2010, were focused primarily on maximizing the value of our RNAi platform through the establishment and support of new business ventures and other potential opportunities (75%), providing support to our early discovery and development efforts around programs and delivery efforts (15%), and supporting organizational and career development objectives for our scientists (10%). Following his promotion to chief scientific officer, Dr. Koblan maintained these objectives, but focused primarily on leading our current discovery programs and coordinating with senior leadership for our ongoing clinical programs. Our compensation committee also considered both Dr. Maraganore’s and Mr. Greene’s recommendations with respect to Dr. Koblan’s performance. Our compensation committee determined that Dr. Koblan achieved 65% of his individual objectives for 2010, including progress in our research and technology efforts and advancement of our clinical pipeline. Our compensation committee determined that under the 2010 annual incentive program, Dr. Koblan earned a cash incentive award of $19,510, representing 65% of his pro-rated target cash award opportunity, reduced by the corporate performance modifier of 58%.
 
Dr. Vaishnaw’s individual objectives were focused primarily on continuing to advance our discovery programs and our clinical development programs with a focus on human proof of concept (60%), providing pre-clinical development support for our research efforts (20%), managing and building our clinical and pre-clinical development organization (10%) and providing support for key alliances and external communications with investors and academic and medical thought leaders (10%). Our compensation committee also considered both Dr. Maraganore’s and Mr. Greene’s recommendations with respect to Dr. Vaishnaw’s performance. Our compensation committee determined that Dr. Vaishnaw achieved 80% of his individual objectives for 2010, including in particular through the advancement of our clinical pipeline. Our compensation committee determined that under the 2010 annual incentive program, Dr. Vaishnaw earned a cash incentive award of $32,735, representing 80% of his target cash award opportunity, reduced by the corporate performance modifier of 58%.
 
Ms. Allen’s individual objectives were focused on meeting specified financial goals, including meeting internal operating expense levels of no more than $110 million under our annual operating plan, and a year-end minimum cash balance requirement of greater than $340 million (excluding a potential one-time license payment from a collaborator) (25%), supporting business development efforts to establish strategic alliances to


29


Table of Contents

fund our business (20%), managing our investment portfolio (25%), managing the audit of our financial statements, along with various public reporting obligations and tax matters (20%), and achieving specified metrics with respect to the information technology and facilities groups (10%). Ms. Allen’s goals relating to internal operating expense levels were based upon our annual operating plan. Multiple factors go into determining our operating plan, which contains financial targets and budgets that we use to guide our operations. Internal operating expenses do not align with reported GAAP operating expenses, as they consist primarily of cash operating expenses and exclude items such as depreciation and stock-based compensation. Our compensation committee also considered both Dr. Maraganore’s and Mr. Greene’s recommendations with respect to Ms. Allen’s performance. Our compensation committee determined that Ms. Allen achieved 75% of her individual objectives for 2010, including meeting year-end internal operating expense levels of no more than $110 million under our annual operating plan and achievement of an internal year-end cash balance objective of greater than $340 million, ending 2010 with $350 million. Our compensation committee determined that under the 2010 annual incentive program, Ms. Allen earned a cash incentive award of $21,357, representing 75% of her target cash award opportunity, reduced by the corporate performance modifier of 58%.
 
Equity Awards
 
Our equity awards program is designed to:
 
  •  reward demonstrated leadership and performance;
 
  •  align our executive officers’ interests with those of our stockholders;
 
  •  retain our executive officers through the term of the awards;
 
  •  maintain competitive levels of executive compensation; and
 
  •  motivate our executive officers for outstanding future performance.
 
The market for qualified and talented executives in the biopharmaceutical industry is highly competitive and we compete for talent with many companies that have greater resources than we do. Accordingly, we believe equity compensation is a crucial component of any competitive executive compensation package we offer.
 
Historically, our equity awards have taken the form of stock options. We typically grant stock options to each of our executive officers upon commencement of employment, annually in conjunction with our review of individual performance and in connection with a promotion.
 
All stock option awards to our executive officers are approved by our compensation committee and, other than stock option awards to new hires, are typically granted at our compensation committee’s regularly scheduled meeting at the end of the year. Stock option awards vary among our executive officers based on their positions and annual performance assessments. In addition, our compensation committee reviews all components of the executive’s compensation to ensure that his or her total compensation is aligned with our overall philosophy and objectives. All stock options granted to our executives have exercise prices equal to the fair market value of our common stock on the date of grant, so that the recipient will not earn any compensation from his or her options unless our share price increases above the value on the date of grant.
 
In addition, the stock options granted to our executive officers typically vest over four years, which we believe provides an incentive to our executives to add value to the company over the long-term and to remain with Alnylam. Typically, the stock options we grant to our executives have a ten-year term and vest as to 25% of the shares on the first anniversary of the grant date and as to an additional 6.25% of the shares at the end of each successive three-month period following the first anniversary of the grant date until the fourth anniversary of the grant date. Vesting ceases upon termination of employment and exercise rights typically cease three months following termination of employment, except in the case of death or disability. Prior to the exercise of an option, the stock option holder does not have any rights as a stockholder with respect to the shares subject to such option, including voting rights and the right to receive dividends or dividend equivalents.

The number of stock options granted to our named executive officers during 2010, and the value of those awards determined in accordance with Financial Accounting Standards Board, or FASB, Accounting Standard Codification, or ASC, Topic 718, are shown in the 2010 Grants of Plan-Based Awards table below. We do not have any equity ownership guidelines for our executives.
 
In connection with the annual review of our executive officer’s individual performance and consistent with our compensation philosophy, our compensation committee approved annual equity incentive awards for each of our executive officers. The annual incentive awards granted to each of our named executive officers are set forth in the table below:
 
         
2010 Annual Equity Incentive Awards

Upon hire, Dr. Reid received a stock option award to purchase 175,000 shares of common stock in June 2010. Dr. Koblan also received a new hire stock option award to purchase 100,000 shares of common stock in April 2010, as well as an additional stock option award to purchase 50,000 shares of common stock in connection with his promotion to chief scientific officer in September 2010.
 
Benefits and Other Compensation
 
Other compensation to our executives consists primarily of the broad-based benefits we provide to all employees, including health and dental insurance, life and disability insurance, an employee stock purchase plan and a 401(k) plan, except that executive officers are not eligible to participate in our employee stock purchase plan. Our 401(k) plan is a tax-qualified retirement savings plan pursuant to which all U.S. based employees, including executive officers, are able to contribute the lesser of up to 60% of their annual salary or the limit prescribed by the Internal Revenue Service on a before-tax basis. We match, in the form of shares of our common stock, 50% of the first 6% of a plan participant’s pay that is contributed to the plan. Our contribution is made at the end of each quarter up to an annual maximum number of shares with a value of $5,250 for each participant. Our matching contributions become 50% vested after the employee has been employed by us for one year and fully vested after the employee has been employed by us for two years.
 
Severance and Other Employment Arrangements
 
Pursuant to the terms of his letter of employment, Dr. Reid is also entitled to a supplemental signing bonus of $25,000 on each anniversary of his date of hire beginning in 2011 and ending in 2014, provided he continues to be our employee on each such anniversary date.
 
In connection with his promotion to chief scientific officer, our compensation committee approved a one-time bonus payment of $110,000 to Dr. Koblan, which was paid in January 2011. In the event that, prior to October 19, 2012, Dr. Koblan either (i) voluntarily terminates his employment with us, other than for “good reason” (as defined in the bonus letter), or (ii) is terminated by us for “cause” (as defined in the bonus letter), he will be required to repay to us $100,000 if such termination occurs before October 19, 2011, and $50,000 if it occurs after October 18, 2011 but before October 19, 2012.
 
In February 2011, Ms. Allen resigned as our vice president of finance and treasurer. In connection with her resignation, we and Ms. Allen entered into a separation agreement, under which we have agreed to provide Ms. Allen with the following severance pay and benefits in consideration for her agreement to a general release and certain other standard terms and conditions: (i) severance in the gross amount of $250,397 (an amount equal to 12 months of Ms. Allen’s gross base salary); (ii) the full cost of any COBRA premiums until the earlier of March 21, 2012 and the date Ms. Allen becomes eligible for coverage under the group

health plan of another employer; (iii) a consulting agreement for a period of up to 12 months following her separation date under which she will perform certain services at our request, the terms of which are described below; and (iv) continued vesting of any unvested stock options held by Ms. Allen during the term of the consulting agreement. In connection with the execution of the separation agreement, we and Ms. Allen also entered into a consulting agreement. The consulting agreement has a term of one year and may be terminated by either party in the event of an uncured material breach of its terms by the other party.
 
In February 2011, we appointed Mr. Michael P. Mason as our vice president of finance and treasurer and as our principal financial and accounting officer.
 
Cash Incentive Compensation for Our Named Executive Officers in 2011
 
In February 2011, our compensation committee approved the annual incentive program for 2011. During 2010, our compensation committee reviewed the annual incentive program relative to marketplace norms and practices by comparing current proxy statement data and compensation survey data. This review was intended to evaluate the competitiveness of our executive compensation through comparisons with a peer group and determine whether changes to our compensation programs, in particular our annual incentive program, were needed. Based upon this review, our compensation committee modified the terms of our annual cash incentive program to increase annual cash incentive award opportunities for 2011 from at or below the 25th percentile to the 50th percentile of our peer group. The table below shows the target award under the incentive program as a percentage of each executive officer’s annual base salary in each of 2010 and 2011, as well as the maximum cash award opportunity in dollars for 2011.

* In February 2011, Ms. Allen resigned and Mr. Mason was appointed as our vice president of finance and treasurer. Mr. Mason previously served as our senior director of finance and controller. Mr. Mason’s base salary for 2011 is $240,000.
 
Each bonus award for 2011 will range from 0% to 100% of the individual’s target award (capped at 100%), thus making each individual’s target award the maximum bonus award achievable in 2011. In determining the 2011 cash incentive compensation for our named executive officers under the 2011 annual incentive program, our compensation committee will review the performance of the company during 2011. In particular, in making its determination, our compensation committee will consider our success against the following corporate goals:

Table of Contents

                 
            Relative
2011 Corporate Goals   Weighting
 
  Achieve “Alnylam 5x15” pipeline goals, including:        
         ○   Complete Phase I clinical study of ALN-TTR01 in patients with ATTR and report data;     15 %
         ○   File an IND or comparable foreign regulatory application for ALN-TTR02 for the treatment of ATTR;     15 %
         ○   File an IND or comparable foreign regulatory application for ALN-PCS for the treatment of severe hypercholesterolemia;     15 %
         ○   Advance ALN-HPN for the treatment of refractory anemia towards the clinic; and     5 %
         ○   Identify and advance two additional RNAi therapeutic programs targeting genetically defined diseases.     5 %
  Achieve “Partner-Based Program” pipeline goals, including:        
         ○   Advance ALN-RSV01 in a Phase IIb clinical trial for the treatment of RSV infection in adult lung transplant patients;     5 %
         ○   Advance Phase I clinical development of ALN-VSP for the treatment of liver cancers and report additional data; seek partner for Phase II clinical development; and     5 %
         ○   Advance ALN-HTT for the treatment of Huntington’s disease towards the clinic.     5 %
  Form additional strategic alliances and new business ventures.     10 %
  Achieve a year-end cash balance of greater than $275 million.     20 %
             
        Total     100 %
 
Under the 2011 annual incentive program, bonus awards, if any, will be determined by first establishing a bonus pool. The bonus pool will be calculated by adding the maximum awards for all eligible plan participants and then multiplying that sum by a modifier established by our compensation committee that is based on our performance as measured against the 2011 corporate goals. This corporate performance level will range from 0% to 100%, provided that if the corporate performance level for 2011 falls below 50%, no bonus awards will be made. The bonus pool will be allocated among all of the plan participants based upon a consideration of each plan participant’s level within the organization, base salary and performance against their individual goals. Bonus awards for our executive officers will be based upon achievement of our corporate goals. Our compensation committee may also consider, in its discretion, each individual executive officer’s contributions to achievement of the 2011 corporate goals. Our compensation committee retains the discretion under the 2011 annual incentive program to adjust upward or downward any bonus award and/or the bonus pool as it deems appropriate. We expect to pay any cash incentive awards made under our 2011 annual incentive program in January 2012.
 
Compliance with IRS Code Section 162(m)
 
Section 162(m) of the Internal Revenue Code of 1986, as amended, generally disallows a tax deduction to public companies for compensation in excess of $1 million paid to a company’s chief executive officer and its three other officers (other than the chief financial officer) whose compensation is required to be disclosed to stockholders pursuant to the Exchange Act by reason of being among the company’s most highly compensated officers. Qualified performance-based compensation is not subject to the deduction limitation if specified requirements are met. We periodically review the potential effects of Section 162(m) and we consider whether to structure the performance-based portion of our executive compensation to comply with exemptions in Section 162(m), so that the compensation remains tax deductible to us. However, our compensation committee may, in its judgment, authorize compensation payments that do not comply with the exemptions in Section 162(m) when it believes that such payments are appropriate to attract, motivate and retain executive talent and are in our best interest and that of our stockholders.

Stock Option Granting Practices
 
Delegation to Our Chief Executive Officer
 
Currently, all of our employees, including our named executive officers, are eligible to participate in our Amended and Restated 2004 Stock Incentive Plan and our 2009 Stock Incentive Plan. All new full-time employees are granted stock options when they start employment and all continuing employees are eligible for stock option awards on an annual basis based on performance and upon promotions to positions of greater responsibility. Our compensation committee has delegated to Dr. Maraganore, our chief executive officer, the authority to make stock option awards under our Amended and Restated 2004 Stock Incentive Plan and our 2009 Stock Incentive Plan to new hires and in connection with promotions, other than grants to vice presidents and executive officers. The number of stock options he may grant to any one individual must be within the range specifically set by our board for these awards. The exercise price of such stock options must be equal to the closing price of our common stock on the NASDAQ Global Market on the date of grant. With respect to stock option awards to new hires other than vice presidents and executive officers, Dr. Maraganore approves the award prior to the employee’s first date of employment with such authority and provides that the award is to be granted to the new hire on his or her first date of regular employment. With respect to stock option awards made in connection with promotions other than of vice presidents and executive officers, Dr. Maraganore approves the award in connection with such promotion and provides that the award is to be granted on the first business day of the calendar month following the date of such promotion; provided, however, that if such first business day is within ten calendar days of the date of such promotion, the grant date shall be the close of business on the first business day of the subsequent calendar month. Dr. Maraganore is required to maintain a list of stock options granted pursuant to such delegated authority and report to our compensation committee regarding such awards.
 
Report of the Compensation Committee on Executive Compensation
 
Our compensation committee has reviewed and discussed the “Compensation Discussion and Analysis” required by Item 402(b) of Regulation S-K with management. Based upon such review and discussions, our compensation committee recommended to our board that such section be included in this proxy statement and incorporated by reference in our Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the SEC on February 18, 2011.

(4) In February 2011, Ms. Allen resigned from her position as vice president of finance and treasurer.
 
(5) Pursuant to the terms of his letter of employment, we paid Dr. Reid a signing bonus of $50,000 in July 2010. In the event that Dr. Reid either voluntarily terminates his employment with us, other than for good reason, or is terminated by us for cause, within the first 24 months of his employment with us, he will be required to repay the full amount of this signing bonus.
 
(6) We did not grant any restricted stock awards or stock appreciation rights to our named executive officers in 2010, 2009 or 2008.
 
(7) The amounts reported in the Option Awards column represent the aggregate grant date fair value for the fiscal years ended December 31, 2010, 2009 and 2008 of grants of stock options to each of the named executive officers, calculated in accordance with the provisions of FASB ASC Topic 718. The assumptions we used in calculating these amounts are included in Note 9 of our audited consolidated financial statements for the year ended December 31, 2010 included in our Annual Report on Form 10-K, filed with the SEC on February 18, 2011. To see the value actually received by the named executive officer in 2010, see the 2010 Option Exercises and Stock Vested table appearing below.

Details of each of the stock option awards reflected above can be found in the Outstanding Equity Awards at Fiscal Year-End for 2010 table appearing below.
 
The amounts reported in the Summary Compensation Table for these stock option awards may not represent the amounts that the named executive officers will actually realize from the awards. Whether, and to what extent, a named executive officer realizes value will depend on our actual operating performance, stock price fluctuations and the named executive officer’s continued employment.
 
(8) In February 2010, our compensation committee authorized the implementation of the annual cash incentive program for fiscal year 2010. The 2010 annual cash incentive program is described above in the “Compensation Discussion and Analysis” under the heading “2010 Annual Incentive Program.” In February 2009, our compensation committee authorized the implementation of the annual cash incentive program for fiscal year 2009. The 2009 annual cash incentive program was described in the “Compensation Discussion and Analysis” under the heading “2009 Annual Incentive Program,” in our 2010 proxy statement, filed with the SEC on April 20, 2010. We did not award cash bonuses to our named executive officers in 2008. In 2008, our compensation committee authorized the implementation of an executive stock option bonus plan, pursuant to which each of our vice presidents and named executive officers was eligible to receive an annual bonus in the form of an award of stock options based upon the achievement of corporate goals and individual objectives that were approved by our compensation committee for 2008.
 
(9) The amounts reported in the All Other Compensation column reflect, for each named executive officer, with the exception of Dr. Koblan, the sum of (i) the dollar value of life insurance premiums we paid; (ii) the amount we contributed to the 401(k) plan in respect of such executive officer; and (iii) the incremental cost to us of all perquisites and other personal benefits. Specifically, the All Other Compensation column above includes:

(1) None of our named executive officers received restricted stock awards or stock appreciation rights in 2010. Dr. Reid joined Alnylam as our senior vice president and chief business officer in June 2010 and received an on-hire stock option award at that time. Dr. Koblan joined Alnylam in April 2010 and was promoted to our chief scientific officer in September 2010, and received on-hire and promotion-related stock option awards, respectively, in connection with these events. The stock option awards reported in the 2010 Grants of Plan-Based Awards table were granted pursuant to our Amended and Restated 2004 Stock Incentive Plan. Our Amended and Restated 2004 Stock Incentive Plan provides that the option exercise price may not be less than 100% of the fair market value of our common stock on the date of grant. These stock options vest as to 25% of the shares on the first anniversary of the grant date and as to an additional 6.25% of the shares at the end of each successive three-month period thereafter until the fourth anniversary of the grant date.
 
(2) The amounts shown in the threshold, target and maximum columns reflect the minimum, target and maximum amounts payable, respectively, under our 2010 annual cash incentive program, which is described above in the “Compensation Discussion and Analysis” under the heading “2010 Annual Incentive Program.” The actual amounts paid to each named executive officer can be found above in the Summary Compensation Table under the column entitled Non-Equity Incentive Plan Compensation.
 
(3) The Grant Date Fair Value, computed in accordance with FASB ASC Topic 718, represents the value of stock options granted during the year.
 
The amounts reported in the 2010 Grants of Plan-Based Awards table for these stock option awards reflect our accounting expense and may not represent the amounts our named executive officers will actually realize from the awards. Whether, and to what extent, a named executive officer realizes value will depend on our actual operating performance, stock price fluctuations and that named executive officer’s continued employment.

Potential Payments Upon Termination or Change-in-Control
 
We do not have agreements with any of our executive officers pursuant to which they are eligible for potential payments upon termination or change in control of Alnylam.
 
As described above in “Related Person Transactions,” in connection with Ms. Allen’s resignation, we agreed to provide Ms. Allen with the following severance pay and benefits: (i) severance in the gross amount of $250,397 (an amount equal to 12 months of Ms. Allen’s gross base salary); (ii) the full cost of any COBRA premiums until the earlier of March 21, 2012 and the date Ms. Allen becomes eligible for coverage under the group health plan of another employer; (iii) a consulting agreement for a period of up to 12 months following her separation date under which she will perform certain services at our request, the terms of which are described below; and (iv) continued vesting of any unvested stock options held by Ms. Allen during the term of the consulting agreement. In connection with the execution of the separation agreement, we and Ms. Allen also entered into a consulting agreement. Under the consulting agreement, Ms. Allen will provide consulting services to us with respect to general accounting, operating budget, public company financial reporting and treasury-related activities. The consulting agreement has a term of one year and may be terminated by either party in the event of an uncured material breach of its terms by the other party.

Employment Arrangements
 
Each executive officer has signed a nondisclosure, invention and non-competition agreement providing for the protection of our confidential information and ownership of intellectual property developed by such executive officer and a covenant not to compete with us for a period of eighteen months after termination of employment.
 
Pursuant to the terms of his letter of employment, Dr. Reid is also entitled to a supplemental signing bonus of $25,000 on each anniversary of his date of hire beginning in 2011 and ending in 2014, provided he continues to be our employee on each such anniversary date.

Compensation of Directors
 
We compensate our non-employee directors for their service as directors. We do not pay directors who are also our employees any additional compensation for their service as a director. Accordingly, Dr. Maraganore does not receive any additional compensation for his service as a director.
 
Our compensation committee periodically reviews the compensation we pay our non-employee directors. Our compensation committee compares our board compensation to compensation paid to non-employee directors of similarly sized public companies at a similar stage of development in the biotechnology industry. Our compensation committee also considers the responsibilities we ask of our board members along with the amount of time required to perform those responsibilities.
 
Each non-employee director is entitled to receive a cash fee of $50,000 per year. The chairs of our board and our nominating and corporate governance committee are each entitled to receive an additional $5,000 per

year, the chair of our compensation committee is entitled to receive an additional $10,000 per year and the chair of our audit committee is entitled to receive an additional $15,000 per year. Each non-employee director is also entitled to receive upon his or her initial election to our board a stock option award for 30,000 shares of common stock, vesting annually over three years, and an additional stock option award to purchase 15,000 shares of common stock at each year’s annual meeting at which he or she served as a director, vesting in full on the first anniversary of the date of grant. In addition, the chair of our audit committee is entitled to an additional stock option award to purchase 10,000 shares of common stock per year. Our board may, in its discretion, increase or decrease the size of the award made to a director upon election or in connection with the annual stock option award or make other option awards to our directors. The exercise price of these stock options is the fair market value of our common stock on the date of grant. We also reimburse our directors for reasonable travel and other related expenses incurred in connection with their service on our board.
 
The following table sets forth information concerning the compensation of our current and former non-employee directors in 2010.

(c) The Grant Date Fair Value computed in accordance with FASB ASC Topic 718 represents the value of stock options granted during 2010. The weighted-average grant date fair value per option was $7.01. There can be no assurance that the Grant Date Fair Value computed in accordance with FASB ASC Topic 718 will ever be realized.
 
(9) This amount reflects compensation paid to Dr. Sharp for service on our scientific advisory board and includes (A) a cash payment of $36,000 paid to Dr. Sharp during 2010 and (B) the aggregate fair value, as measured on December 31, 2010, for stock options granted to him in 2010 to purchase 15,000 shares of our common stock. Because these stock options were compensation for service on our scientific advisory board, they are non-employee awards and, therefore, are accounted for using the fair value method in accordance with FASB ASC Topic 718, under which compensation is generally recognized over the vesting period of the award. Under the fair value method, compensation associated with non-employee stock-based awards is determined based on the estimated fair value of the award, measured using an established option-pricing model. At the end of each financial reporting period prior to vesting, the value of these stock options (as calculated using the Black-Scholes option pricing model) is re-measured using the then current fair value of our common stock. The assumptions we used to calculate this amount is included in Note 9 to our audited consolidated financial statements for the fiscal year ended December 31, 2010 included in our Annual Report on Form 10-K, filed with the SEC on February 18, 2011.
 
Compensation Committee Interlocks and Insider Participation
 
During 2010, the members of our compensation committee were Dr. Sato and Mr. Starr, and through his retirement in September 2010, Mr. Vincent, none of whom was a current or former officer or employee of Alnylam and none of whom had any related person transaction involving Alnylam.

PROPOSAL 2 — ADVISORY VOTE ON EXECUTIVE COMPENSATION
 
We are providing our stockholders the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the SEC’s rules. This proposal, which is commonly referred to as “say-on-pay,” is required by the recently enacted Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which added Section 14A to the Exchange Act. Section 14A of the Exchange Act also requires that stockholders have the opportunity to cast an advisory vote with respect to whether future executive compensation advisory votes will be held every one, two or three years, which is the subject of Proposal 3.
 
We encourage stockholders to read closely the “Executive Compensation” section of this proxy statement beginning with the “Compensation Discussion and Analysis” on page 23, which describes in detail our executive compensation programs and the decisions made by our compensation committee and our board with respect to the fiscal year ended December 31, 2010.
 
As we describe in the “Compensation Discussion and Analysis,” we maintain simple executive compensation programs that consist almost entirely of base salary, an annual cash incentive bonus and annual equity awards. These elements of compensation have been selected by our compensation committee because the committee believes that they effectively achieve the fundamental goals of our compensation program, which are to attract, motivate and retain qualified and talented executives, who are critical to our success, motivating them to achieve our business goals and rewarding them for superior short- and long-term performance. The goal of our compensation committee is to ensure that our compensation programs are aligned with the interests of our stockholders and our business goals in order to attain our ultimate objective of increasing stockholder value. We believe that, consistent with these goals, the total compensation paid to each of our named executive officers is fair, reasonable and competitive. Further, we believe our programs do not encourage excessive risk-taking by management.
 
With very limited exceptions, we do not provide any compensation or benefit plans to executive officers that are not also available to other employees. We differentiate among executive officers primarily based on size of annual cash incentive awards and annual equity awards and, to a lesser extent, base salary. Annual compensation decisions for executive officers are made by our compensation committee based on the achievement of specified performance goals as described under “Compensation Discussion and Analysis.”
 
As an advisory vote, this proposal is not binding. The outcome of this advisory vote will not overrule any decision by us or our board of directors (or any committee thereof). However, our compensation committee and board of directors value the opinions expressed by our stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for named executive officers.
 
Board Recommendation
 
Our board of directors recommends that you vote to approve the compensation of our named executive officers by voting “FOR” Proposal 2.

PROPOSAL 3 — ADVISORY VOTE ON THE FREQUENCY OF
FUTURE EXECUTIVE COMPENSATION ADVISORY VOTES
 
In Proposal 2, we are providing our stockholders the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our named executive officers. In this Proposal 3, we are asking our stockholders to cast a non-binding advisory vote regarding the frequency of future executive compensation advisory votes. Stockholders may vote for a frequency of every one, two or three years, or may abstain.
 
After careful consideration, our board believes that an executive compensation advisory vote should be held every year. Our board believes that an annual executive compensation advisory vote will facilitate more direct stockholder input about executive compensation. An annual executive compensation advisory vote is consistent with our policy of reviewing our compensation programs annually, as well as seeking frequent input from our stockholders on corporate governance and executive compensation matters. We believe an annual vote would be the best governance practice for our company at this time.
 
The frequency choice that receives the highest number of votes cast will be considered to be the preferred frequency of our stockholders with which we are to hold future non-binding stockholder advisory “say-on-pay” votes on executive compensation.
 
Our board of directors will take into consideration the outcome of this vote in determining the frequency of future executive compensation advisory votes. However, because this vote is advisory and non-binding, our board of directors may decide that it is in our best interests and those of our stockholders to hold the advisory vote to approve executive compensation more or less frequently.
 
Board Recommendation
 
Our board of directors believes that holding the Executive Compensation Advisory Vote every year is in our best interests and those of our stockholders and recommends voting “For” a frequency of every “ONE YEAR.”
 
Stockholders are not voting to approve or disapprove the board of directors’ recommendation. Stockholders may choose among the four choices available.
 
PROPOSAL 4 — RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS
 
Our board has appointed the firm of PricewaterhouseCoopers LLP, an independent registered public accounting firm, as independent auditors for the fiscal year ending December 31, 2011. Although stockholder approval of our board’s appointment of PricewaterhouseCoopers LLP is not required by law, our board believes that it is advisable to give stockholders an opportunity to ratify this appointment. If this proposal is not approved at the annual meeting, our board will reconsider its appointment of PricewaterhouseCoopers LLP. Representatives of PricewaterhouseCoopers LLP are expected to be present at the annual meeting and will have the opportunity to make a statement, if they desire to do so, and will be available to respond to appropriate questions from our stockholders.
 
Board Recommendation
 
Our board of directors recommends a vote “FOR” the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditors for the fiscal year ending December 31, 2011.

STOCKHOLDER PROPOSALS
 
In order to be included in proxy material for the 2012 annual meeting of stockholders, stockholders’ proposals must be received by us at our principal executive offices, 300 Third Street, Cambridge, Massachusetts 02142 no later than January 3, 2012.

However, if the 2012 annual meeting of stockholders is advanced by more than 20 days, or delayed by more than 60 days, from the first anniversary of the 2011 annual meeting of stockholders, notice must be received not earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of (1) the 90th day prior to such annual meeting and (2) the 10th day following the date on which notice of the date of such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever occurs first. Our bylaws also specify requirements relating to the content of the notice which stockholders must provide, including a stockholder nomination for election to our board of directors, to be properly presented at the 2012 annual meeting of stockholders.
 
OUR BOARD OF DIRECTORS ENCOURAGES STOCKHOLDERS TO ATTEND THE ANNUAL MEETING. WHETHER OR NOT YOU PLAN TO ATTEND IN PERSON, YOU ARE URGED TO VOTE BY PROXY OVER THE INTERNET, BY TELEPHONE OR BY MAIL AS DESCRIBED IN THE ENCLOSED PROXY CARD. A PROMPT RESPONSE WILL GREATLY FACILITATE ARRANGEMENTS FOR THE ANNUAL MEETING AND YOUR COOPERATION WILL BE APPRECIATED. STOCKHOLDERS WHO ATTEND THE ANNUAL MEETING MAY VOTE THEIR STOCK PERSONALLY EVEN THOUGH THEY HAVE SUBMITTED A PROXY PREVIOUSLY.

statements and the Company’s internal control over financial reporting and for reviewing the Company’s unaudited interim financial statements. The authority and responsibilities set forth in this Charter do not reflect or create any duty or obligation of the Audit Committee to plan or conduct any audit, to determine or certify that the Company’s financial statements are complete, accurate, fairly presented, or in accordance with generally accepted accounting principles or applicable law, or to guarantee the independent auditor’s reports.
 
Oversight of Independent Auditor

EXHIBIT A
 
ALNYLAM PHARMACEUTICALS, INC.
 
RELATED PERSON TRANSACTION POLICY
 
The Code of Business Conduct and Ethics of Alnylam Pharmaceuticals, Inc. (the “Company”) provides that employees, executive officers and directors must act in the best interests of the Company and refrain from engaging in any activity or having a personal interest that presents a “conflict of interest.” In addition, under applicable SEC rules, the Company is required to disclose related person transactions as defined in the SEC’s rules.
 
The Company’s Board of Directors (the “Board”) has adopted this Related Person Transaction Policy (this “Policy”) to set forth the policies and procedures for the review and approval or ratification of Related Person Transactions (as defined below).
 
1.   Definitions
 
For the purposes of this Policy, a “Related Person” is:
 
a) any person who is or was an executive officer, director, or director nominee of the Company at any time since the beginning of the Company’s last fiscal year;
 
b) a person who is or was an Immediate Family Member of an executive officer, director, director nominee at any time since the beginning of the Company’s last fiscal year;
 
c) any person who, at the time of the occurrence or existence of the transaction, is the beneficial owner of more than 5% of any class of the Company’s voting securities (a “Significant Shareholder”); or
 
d) any person who, at the time of the occurrence or existence of the transaction, is an Immediate Family Member of a Significant Shareholder of the Company.
 
An “Immediate Family Member” of a person is any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of such person, or any other person sharing the household of such person, other than a tenant or employee.
 
A “Related Person Transaction” is any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships in which the Company was or is to be a participant, the amount involved exceeds $120,000, and a Related Person had or will have a direct or indirect material interest. Except as otherwise set forth in this Policy, “Related Person Transaction” specifically includes, without limitation, purchases of goods or services by or from the Related Person or entities in which the Related Person has a material interest, indebtedness, guarantees of indebtedness, and employment by the Company of a Related Person. The Board has determined that the following do not create a material direct or indirect interest on behalf of the Related Person, and are, therefore, not “Related Person Transactions” for purposes of this Policy:
 
1. Interests arising only from the Related Person’s position as a director of another corporation or organization that is a party to the transaction; or
 
2. Interests arising only from the direct or indirect ownership by the Related Person and all other Related Persons in the aggregate of less than a 10% equity interest (other than a general partnership interest) in another entity which is a party to the transaction; or
 
3. Interests arising from both the position and ownership level described in (1) and (2) above; or
 
4. Interests arising solely from the Related Person’s position as an executive officer of another entity (whether or not the person is also a director of such entity) that is a participant in the transaction, where (a) the Related Person and all other Related Persons own in the aggregate less than a 10% equity interest in such entity, (b) the Related Person and his or her Immediate Family Members are not involved in the negotiation of the terms of the transaction with the Company and do not receive any special benefits as a

result of the transaction, and (c) the amount involved in the transaction equals less than the greater of $200,000 or 5% of the annual gross revenues of the company receiving payment under the transaction; or
 
5. Interests arising solely from the ownership of a class of the Company’s equity securities if all holders of that class of equity securities receive the same benefit on a pro rata basis; or
 
6. A transaction that involves compensation to an executive officer if the compensation has been approved, or recommended to the Board for approval, by the Compensation Committee of the Board or a group of independent directors of the Company performing a similar function; or
 
7. A transaction that involves compensation to a director for services as a director of the Company if such compensation will be reported pursuant to Item 402(k) of Regulation S-K; or
 
8. A transaction that is specifically contemplated by provisions of the Certificate of Incorporation or Bylaws of the Company; or
 
9. Interests arising solely from indebtedness of a Significant Shareholder or an Immediate Family Member of a Significant Shareholder to the Company; or
 
10. A transaction where the rates or charges involved in the transaction are determined by competitive bids; or
 
11. A transaction that involves the rendering of services as a common or contract carrier or public utility at rates or charges fixed in conformity with law or governmental authority; or
 
12. A transaction that involves services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services.
 
2.   Policies and Procedures for Review, Approval or Ratification of Related Person Transactions
 
Any Related Person Transaction proposed to be entered into by the Company must be reported to the General Counsel of the Company and shall be reviewed and approved by the Audit Committee of the Board (the “Committee”) in accordance with the terms of this Policy, prior to effectiveness or consummation of the transaction, whenever practicable. If the General Counsel determines that advance approval of a Related Person Transaction is not practicable under the circumstances, the Committee shall review and, in its discretion, may ratify the Related Person Transaction at the next meeting of the Committee, or at the next meeting following the date that the Related Person Transaction comes to the attention of the General Counsel; provided, however, that the General Counsel may present a Related Person Transaction arising in the time period between meetings of the Committee to the Chair of the Committee, who shall review and may approve the Related Person Transaction, subject to ratification by the Committee at the next meeting of the Committee.
 
In addition, any Related Person Transaction previously approved by the Committee or otherwise already existing that is ongoing in nature shall be reviewed by the Committee annually to ensure that such Related Person Transaction has been conducted in accordance with the previous approval granted by the Committee, if any, and that all required disclosures regarding the Related Person Transaction are made.
 
Transactions involving compensation of executive officers shall be reviewed and approved by the Compensation Committee in the manner specified in the charter of the Compensation Committee.
 
3.   Standards for Review, Approval or Ratification of Related Person Transactions
 
A Related Person Transaction reviewed under this Policy will be considered approved or ratified if it is authorized by the Committee in accordance with the standards set forth in this Policy after full disclosure of the Related Person’s interests in the transaction. As appropriate for the circumstances, the Committee shall review and consider:
 
  •  the Related Person’s interest in the Related Person Transaction;
 
  •  the approximate dollar value of the amount involved in the Related Person Transaction;


A-6


Table of Contents

 
  •  the approximate dollar value of the amount of the Related Person’s interest in the transaction without regard to the amount of any profit or loss;
 
  •  whether the transaction was undertaken in the ordinary course of business of the Company;
 
  •  whether the transaction with the Related Person is proposed to be, or was, entered into on terms no less favorable to the Company than terms that could have been reached with an unrelated third party;
 
  •  the purpose of, and the potential benefits to the Company of, the transaction; and
 
  •  any other information regarding the Related Person Transaction or the Related Person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.
 
The Committee will review all relevant information available to it about the Related Person Transaction. The Committee may approve or ratify the Related Person Transaction only if the Committee determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, the best interests of the Company. The Committee may, in its sole discretion, impose such conditions as it deems appropriate on the Company or the Related Person in connection with approval of the Related Person Transaction.
 
The review, approval or ratification of a transaction, arrangement or relationship pursuant to this Policy does not necessarily imply that such transaction, arrangement or relationship is required to be disclosed under Item 404(a) of Regulation S-K.
