PROXY STATEMENT

INFORMATION CONCERNING VOTING AND SOLICITATION

General

Your proxy is solicited on behalf of the Board of Directors (the “Board”) of Puma Biotechnology, Inc., a Delaware corporation (the “Company,” “we,” “us” or “our”), for use at our 2016 annual meeting of stockholders to be held on Monday, June 13, 2016, at 1:00 p.m. local time, at the Luxe Sunset Boulevard Hotel, 11461 Sunset Boulevard, Los Angeles, California 90049, or at any continuation, postponement or adjournment thereof (the “annual meeting”), for the purposes discussed in this proxy statement and in the accompanying Notice of Annual Meeting and any business properly brought before the annual meeting. Proxies are solicited to give all stockholders of record an opportunity to vote on matters properly presented at the annual meeting.

In accordance with the Securities and Exchange Commission’s “notice and access” model, we have elected to provide access to our proxy materials, including our notice of annual meeting, this proxy statement and our annual report to stockholders, over the Internet. Accordingly, on or about April 29, 2016, we intend to make our proxy materials available on the Internet and to mail a Notice of Internet Availability of Proxy Materials (the “Notice”) to all stockholders of record. On or about April 29, 2016, we also intend to mail a paper copy of the proxy materials and proxy card to other stockholders of record who have elected to receive such materials in paper form. Brokers and other nominees who hold shares on behalf of beneficial stockholders will be sending their own similar notice. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or to request to receive a printed set of the proxy materials. Instructions on how to request a printed copy by mail or electronically may be found on the Notice and on the website referred to in the Notice, including an option to request paper copies on an ongoing basis. If you properly request a printed copy of the proxy materials, we intend to mail the proxy materials, together with a proxy card, to you, within three business days of such request.

Important Notice Regarding the Availability of Proxy Materials for the 2016 Annual Meeting of Stockholders to be Held on June 13, 2016

The Notice of Annual Meeting, this proxy statement and our 2015 Annual Report, which consists of a letter to stockholders and our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, are available on our website at http://investor.pumabiotechnology.com/annual-meeting. This website address contains the following documents: the Notice, the proxy statement and proxy card sample, and the 2015 Annual Report. You are encouraged to access and review all of the important information contained in the proxy materials before voting.

Who Can Vote

You are entitled to vote at the annual meeting if you were a stockholder of record of our common stock as of the close of business on April 20, 2016. You are entitled to one vote for each share of common stock held on all matters to be voted upon at the annual meeting. Your shares may be voted at the annual meeting only if you are present in person or represented by a valid proxy.

Voting of Shares

You may vote by attending the annual meeting and voting in person or you may submit a proxy to have your shares voted at the annual meeting. The method of submitting your proxy will differ depending on whether you are viewing this proxy statement on the Internet or receiving a paper copy and whether you are a beneficial stockholder or a stockholder of record.

Beneficial Stockholders. Beneficial stockholders hold their shares through a broker, bank, trustee or other nominee (that is, in “street name”) rather than directly in their own name. If you hold your shares in street name,

you are a “beneficial stockholder,” and the Notice and proxy materials were made available to you by the organization holding your account. This organization is considered the stockholder of record for purposes of voting at the annual meeting. As a beneficial stockholder, you have the right to instruct that organization on how to vote the shares held in your account. If you requested printed copies of the proxy materials by mail, you will receive a voting instruction form from your bank, broker, trustee or other nominee.

Stockholders of Record. If your shares are registered directly in your name with our transfer agent, Wells Fargo Bank, N.A., or if you hold stock certificates in your name, you are considered the stockholder of record with respect to those shares, and the Notice and proxy materials were made available directly to you by the Company. If you requested printed copies of the proxy materials by mail, you will receive a proxy card from us.

Whether you are a stockholder of record or a beneficial stockholder, you may direct how your shares are voted without attending the annual meeting. If you are a stockholder of record, you may submit a proxy to authorize how your shares are voted at the annual meeting. You can submit a proxy over the Internet by following the instructions on the website referred to in the Notice or, if you requested and received printed copies of the proxy materials, you can also submit a proxy by mail or telephone pursuant to the instructions on the proxy card enclosed with the proxy materials.

If you are a beneficial stockholder, you may also submit your voting instructions over the Internet by following the instructions provided in the Notice, or, if you requested and received printed copies of the proxy materials, you can also submit voting instructions by telephone or mail by following the instructions provided to you by your bank, broker, trustee or other nominee.

Submitting your proxy or voting instructions via the Internet, by telephone or by mail will not affect your right to vote in person should you decide to attend the annual meeting, although beneficial stockholders must obtain a “legal proxy” from the bank, broker, trustee or other nominee that holds their shares giving them the right to vote the shares at the annual meeting in order to vote in person at the meeting.

The Internet and telephone voting facilities will close at 12:00 noon (CT) on June 12, 2016. If you vote through the Internet, you should be aware that you may incur costs to access the Internet, such as usage charges from telephone companies or Internet service providers and that these costs must be borne by you. If you submit your proxy over the Internet or by telephone, then you need not return a written proxy card by mail. If you intend to submit your proxy over the Internet or by telephone and have not done so prior to 12:00 noon (CT) on June 12, 2016, your only alternative if you wish to vote at the annual meeting will be to attend the annual meeting and vote in person.

YOUR VOTE IS VERY IMPORTANT. You should submit your proxy even if you plan to attend the annual meeting. If you properly give your proxy and submit it to us in time to vote, one of the individuals named as your proxy will vote your shares as you have directed.

All shares entitled to vote and represented by properly submitted proxies (including those submitted electronically, telephonically and in writing) that have not been properly revoked, will be voted at the annual meeting in accordance with the instructions indicated on those proxies. If no direction is indicated on a properly submitted proxy, your shares will be voted “FOR” each of the nominees for director named in the proxy statement, “FOR” the ratification of the selection of PKF Certified Public Accountants as our independent registered public accounting firm, and “FOR” the approval of the amendments to the Company’s Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) to eliminate the ability of stockholders to act by written consent and to eliminate the mandatory indemnification of all persons covered by Section 145 of the General Corporation Law of the State of Delaware. The proxy gives each of Alan H. Auerbach and Charles R. Eyler discretionary authority to vote your shares in accordance with his best judgment with respect to all additional matters that might come before the annual meeting.

Revocation of Proxy

If you are a stockholder of record, you may revoke your proxy at any time before your proxy is voted at the annual meeting by taking any of the following actions:

•

delivering to our Corporate Secretary a signed written notice of revocation, bearing a date later than the date of the proxy, stating that the proxy is revoked;

•

signing and delivering a new paper proxy, relating to the same shares and bearing a later date than the original proxy;

•

submitting another proxy by telephone or over the Internet (the proxy holders will vote your shares in accordance with your latest telephone or Internet voting instructions); or

•

attending the annual meeting and voting in person, although attendance at the annual meeting will not, by itself, revoke a proxy.

Written notices of revocation and other communications with respect to the revocation of proxies should be addressed to:

Puma Biotechnology, Inc.

10880 Wilshire Boulevard, Suite 2150

Los Angeles, CA 90024

Attention: Corporate Secretary

If you are a beneficial stockholder and you submit a voting instruction form, you may change your vote by submitting new voting instructions to your bank, broker, trustee or other nominee in accordance with the procedures of such bank, broker, trustee or other nominee.

Voting in Person

If you plan to attend the annual meeting and wish to vote in person, you will be given a ballot at the annual meeting.

Quorum and Votes Required

At the close of business on April 20, 2016, 32,493,092 shares of our common stock were outstanding and entitled to vote. All votes will be tabulated by the inspector of election appointed for the annual meeting, who will separately tabulate votes “for,” “against,” abstentions and broker non-votes.

Quorum. A majority of the outstanding shares of common stock, present in person or represented by proxy, will constitute a quorum at the annual meeting. Shares of common stock held by persons attending the annual meeting but not voting, shares represented by proxies that reflect abstentions as to a particular proposal and broker “non-votes,” if any, will be counted as present for purposes of determining a quorum.

Broker Non-Votes. Brokers or other nominees who hold shares of common stock in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not allowed to exercise their voting discretion with respect to the election of directors or for the approval of certain “non-routine” matters, without specific instructions from the beneficial owner. These non-voted shares are referred to as “broker non-votes.” Proposal 2 (ratifying the appointment of our independent registered public accounting firm), Proposal 3 (amendment of Certificate of Incorporation to eliminate the ability of stockholders to act by written consent) and Proposal 4 (amendment of Certificate of Incorporation to eliminate the mandatory indemnification of all persons covered by Section 145 of the General Corporation Law of the State of Delaware) are considered routine matters. If you are a beneficial stockholder holding shares through a broker or other nominee and you do

not submit instructions on how your shares should be voted, your broker or other nominee will not be able to vote your shares on Proposal 1 (election of directors).

Votes Required

Proposal 1 – Election of Directors. Directors will be elected by a plurality of the votes of the shares present in person or represented by proxy and entitled to vote. Thus, the five nominees receiving the greatest number of votes “FOR” their election will be elected. Abstentions and broker non-votes are not considered votes cast and therefore will not affect the outcome of the vote.

Proposal 2 – Ratification of Independent Registered Public Accounting Firm. The affirmative vote of a majority of the votes cast at the annual meeting is required for the ratification of the selection of PKF Certified Public Accountants, a Professional Corporation, as our independent registered public accounting firm for the year ending December 31, 2016. Abstentions are not considered votes cast and therefore will not affect the outcome of the vote. Brokers have authority in the absence of timely instructions from their beneficial owners to vote on this proposal. As a result, there will be no broker non-votes for this proposal.

Proposal 3 – Approval of Amendment to Certificate of Incorporation to Eliminate the Ability of Stockholders to Act by Written Consent. The affirmative vote of a majority of the shares issued and outstanding as of the record date is required for approval of this amendment to the Certificate of Incorporation. Abstentions will have the same effect as votes against this proposal. Brokers have authority in the absence of timely instructions from their beneficial owners to vote on this proposal. As a result, there will be no broker non-votes for this proposal.

Proposal 4 – Approval of Amendment to Certificate of Incorporation to Eliminate the Mandatory Indemnification of All Persons Covered by Section 145 of the General Corporation Law of the State of Delaware. The affirmative vote of a majority of the shares issued and outstanding as of the record date is required for approval of this amendment to the Certificate of Incorporation. Abstentions will have the same effect as votes against this proposal. Brokers have authority in the absence of timely instructions from their beneficial owners to vote on this proposal. As a result, there will be no broker non-votes for this proposal.

Solicitation of Proxies

Our Board is soliciting proxies for the annual meeting from our stockholders. We will bear the entire cost of soliciting proxies from our stockholders. In addition to the solicitation of proxies by delivery of the Notice or proxy statement by mail, we will request that brokers, banks and other nominees that hold shares of our common stock, which are beneficially owned by our stockholders, send Notices, proxies and proxy materials to those beneficial owners and secure those beneficial owners’ voting instructions. We will reimburse those record holders for their reasonable expenses. We have engaged Innisfree M&A Incorporated to assist in the solicitation of proxies and provide related advice and informational support for a services fee and the reimbursement of customary disbursements, which are not expected to exceed $25,000 in the aggregate. We may use several of our regular employees, who will not be specially compensated, to solicit proxies from our stockholders, either personally or by telephone, Internet, facsimile or special delivery letter.

Assistance

If you need assistance in submitting your proxy over the Internet or completing your proxy card or have questions regarding the annual meeting, please contact Investor Relations at (424) 248-6500 or ir@pumabiotechnology.com or write to: Puma Biotechnology, Inc., 10880 Wilshire Boulevard, Suite 2150, Los Angeles, CA 90024, Attention: Investor Relations.

CORPORATE GOVERNANCE

Board Leadership Structure and Role in Risk Oversight

Alan H. Auerbach currently serves as our Chairman and Chief Executive Officer. We have no policy requiring the combination or separation of the Chief Executive Officer and Chairman roles and our governing documents do not mandate a particular structure. At present, we have determined that this leadership structure of having a combined Chairman of the Board and Principal Executive Officer is appropriate due to the size and operations and resources of our company. Our Board believes that having these roles combined helps promote efficient and centralized decision-making, focuses the Board’s discussions and facilitates the presentation of the Company’s strategy with a unified voice.

Our Board acknowledges that no single leadership model is right for all companies at all times. As such, our Board periodically reviews its leadership structure and may, depending on the circumstances, including our size, resources and operations, choose a different leadership structure in the future.

Our Board is involved in the general oversight of risks that could affect our business. Our Board satisfies this responsibility through reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within the Company. Further, our Board oversees risks through the establishment of policies and procedures that are designed to guide daily operations in a manner consistent with applicable laws, regulations and risks acceptable to our Company.

Board Independence

Under the listing requirements and rules of the New York Stock Exchange (the “NYSE”), independent directors must comprise a majority of a listed company’s board of directors. In addition, NYSE rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and compensation committee members must satisfy heightened independence criteria set forth in NYSE rules. Under NYSE rules, a director will only qualify as an “independent director” if the company’s board of directors affirmatively determines that the director has no material relationship with the company, either directly or indirectly, that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Our Board has undertaken a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each of our directors concerning his background, employment and affiliations, including family relationships, and on such other due consideration and diligence as it deems appropriate, our Board has determined that each of Messrs. Moyes and Zavrl and Drs. Senderowicz and Wilson is “independent” under the applicable rules and standards established by the U.S. Securities and Exchange Commission (the “SEC”) and the NYSE. In making this determination, our Board considered the current and prior relationships that each non-employee director has with us and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. Our Board has determined that Mr. Auerbach is not independent due to his role as our President and Chief Executive Officer.

Board Meetings

During the fiscal year ended December 31, 2015, our Board held six meetings. All directors attended at least 75% or more of the aggregate number of meetings of the Board and board committees on which they served. We do not have a formal policy relating to director attendance at annual meetings. Mr. Auerbach attended our 2015 annual meeting of stockholders held on June 9, 2015.

Executive Sessions

During the fiscal year ended December 31, 2015, the non-executive directors met in executive session of the Board on four occasions and the members of the Audit Committee met in executive session on five occasions. The policy of our Board is to hold at least four executive sessions of the Board annually and executive sessions of committees when needed. Jay M. Moyes presides over the regularly scheduled executive sessions of the non-management directors.

Board Committees

We have established an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee, and a Stock Option Committee. The composition and responsibilities of each committee are determined by the Board and are described below. To view the charters of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee, please visit the corporate governance section of our website at www.pumabiotechnology.com/about_governance.html. In addition, the charters for these committees are available in print to any stockholder who requests a copy. Please direct all requests to our Corporate Secretary, Puma Biotechnology, Inc., 10880 Wilshire Boulevard, Suite 2150, Los Angeles, CA 90024.

Audit Committee

Our Audit Committee provides oversight over each of our accounting and financial reporting processes, the audit of our consolidated financial statements and our internal control function. Among other matters, the Audit Committee assists our Board in oversight of the independent registered public accounting firm qualifications, independence and performance; is responsible for the engagement, retention and compensation of the independent auditors; reviews the scope of the annual audit; reviews and discusses with management and the independent registered public accounting firm the results of the annual audit and the review of our quarterly consolidated financial statements, including the disclosures in our annual and quarterly reports filed with the SEC; reviews our risk assessment and risk management processes; establishes procedures for receiving, retaining and investigating complaints received by us regarding accounting, internal accounting controls or audit matters; approves audit and permissible non-audit services provided by our independent registered public accounting firm; and reviews and approves related person transactions under Item 404 of Regulation S-K.

The members of our Audit Committee are Messrs. Moyes and Zavrl and Dr. Wilson, with Mr. Moyes serving as the chair of the committee. The Board has determined that each of Messrs. Moyes and Zavrl and Dr. Wilson are independent directors as defined under the applicable rules and regulations of the SEC and the NYSE. The Board has determined that all members of our Audit Committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and the NYSE. Our Board has determined that Mr. Moyes and Dr. Wilson are audit committee financial experts as defined under the applicable rules of the SEC and have the requisite financial sophistication as defined under the applicable rules and regulations of the NYSE. The Audit Committee met nine times during the fiscal year ended December 31, 2015.

Compensation Committee

Our Compensation Committee adopts and administers the compensation policies, plans and benefit programs for our executive officers and all other members of our executive team. In addition, among other things, our Compensation Committee annually evaluates the performance and compensation of our Chief Executive Officer and, in consultation with our Chief Executive Officer, our other executive officers. Based on such evaluation, the Compensation Committee determines and approves all of the compensation of the Chief Executive Officer and other executive officers. The Chief Executive Officer is not permitted to be present during any Compensation Committee final deliberations or voting concerning the compensation of any executive officer, including the Chief Executive Officer. Our Compensation Committee also administers the Puma

Biotechnology, Inc. 2011 Incentive Award Plan (the “Plan”). Additionally, the Compensation Committee annually reviews the compensation and benefits of our non-management directors.

The Compensation Committee is permitted to delegate any or all of its responsibilities to a subcommittee of the Compensation Committee, but only to the extent consistent with our Certificate of Incorporation, Bylaws, Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), the rules and listing standards of the NYSE, and other applicable law. The Compensation Committee has delegated certain of its authority under the Plan to the Stock Option Committee. See “Stock Option Committee.”

The Compensation Committee has the sole discretion to retain or obtain the advice of compensation advisers, including compensation consultants, legal counsel or other advisers in order to assist the Compensation Committee or any of its subcommittees in carrying out its responsibilities. The Compensation Committee is also responsible for the appointment, determination of the compensation and oversight of the work of so retained compensation advisers and the determination of the independence of each compensation adviser prior to selecting or receiving advice from any such compensation adviser and on at least an annual basis thereafter. The Company provides for appropriate funding for payment or reasonable compensation to any compensation adviser to the Compensation Committee.

The Compensation Committee has engaged Radford (the “consultant” or “Radford”) to advise the Compensation Committee on an ongoing basis as an independent compensation consultant. The consultant reports directly to the Compensation Committee. While conducting assignments, the consultant interacts with our management when appropriate. Specifically, our Senior Vice President, Finance and Administration and Treasurer and our senior finance and human resources personnel interact with the consultant from time to time to provide relevant company and executive compensation data. In addition, the consultant may seek feedback from the Chairman of the Compensation Committee, other members of our Board or the Chief Executive Officer regarding its work prior to presenting study results or recommendations to the Compensation Committee. The Compensation Committee determines when to hire, terminate or replace the consultant, and the projects to be performed by the consultant. During 2015, the consultant, at the request of the Compensation Committee, performed a review of the competitiveness of our compensation programs for certain of our senior management. The Compensation Committee may engage the consultant to conduct additional reviews of our senior management compensation programs in the future. In addition, in the future, the consultant, when invited, may attend meetings of the Compensation Committee.

The Compensation Committee reviews the independence of its compensation consultants and other advisors. In performing its analysis, the Compensation Committee considers the factors set forth in applicable SEC rules and the NYSE listing requirements. After review and consultation with Radford, the Compensation Committee has determined Radford is independent and that there is no conflict of interest resulting from retaining Radford currently nor was any conflict raised during the year ended December 31, 2015.

The members of our Compensation Committee are Messrs. Moyes and Zavrl and Dr. Senderowicz, with Mr. Moyes serving as the chair of the committee. The Board has determined that each of the members of our Compensation Committee are independent under the applicable rules and regulations of the SEC and the NYSE, are “outside directors” for purposes of Section 162(m) of the Code and are non-employee directors for purposes of Section 16 of the Exchange Act. The Compensation Committee met four times during the fiscal year ended December 31, 2015.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee is responsible for, among other things, making recommendations regarding corporate governance, the composition of our Board, identification, evaluation and nomination of director candidates and the structure and composition of committees of our Board. In addition, our Nominating and Corporate Governance Committee oversees our corporate governance guidelines, makes

recommendations regarding our committee charters, oversees compliance with our code of business conduct and ethics, contributes to succession planning, reviews actual and potential conflicts of interest of our directors and officers other than related person transactions reviewed by the Audit Committee and oversees the self-evaluation process of our Board. Our Nominating and Corporate Governance Committee also is responsible for making recommendations regarding non-employee director compensation to the full Board.

The process followed by our Nominating and Corporate Governance Committee to identify and evaluate director candidates includes 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 Nominating and Corporate Governance Committee and other members of the Board. In evaluating the suitability of individual candidates (both new candidates and current Board members) to recommend to the Board for nomination (and, in the case of vacancies, appointment), the Nominating and Corporate Governance Committee applies the criteria attached to its charter. These criteria include (i) personal and professional integrity, ethics and values; (ii) experience in corporate management, such as serving as an officer or former officer of a publicly held company, and a general understanding of marketing, finance and other elements relevant to the success of a publicly held company in today’s business environment; (iii) experience in our industry and with relevant social policy concerns; (iv) experience as a board member of another publicly held company; (v) academic expertise in an area of our operations; and (vi) practical and mature business judgment, including ability to make independent analytical inquiries. Each individual is evaluated in the context of the Board as a whole, with the objective of assembling a group that can best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment using his or her diversity of experience in these various areas. While the Nominating and Corporate Governance Committee considers diversity and variety of experiences and viewpoints to be important factors, it does not believe that a director nominee should be chosen solely or mainly because of race, color, gender, national origin or sexual identity or orientation. Thus, although diversity may be a consideration in the Nominating and Corporate Governance Committee’s process, it does not have a formal policy regarding the consideration of diversity in identifying director nominees.

Additionally, the Nominating and Corporate Governance Committee does not have a formal policy with regard to the consideration of any director candidates recommended by stockholders. Because of the size of the Board, the Nominating and Corporate Governance Committee addresses the need to retain members and fill vacancies after discussion among current members. Accordingly, the Nominating and Corporate Governance Committee has determined that a formal policy for considering director candidates recommended by stockholders is not necessary.

The Nominating and Corporate Governance Committee will, however, consider director candidates recommended by stockholders even though it has no requirement to do so. The Nominating and Corporate Governance Committee will consider such candidates on the same basis as it considers all other candidates. A stockholder wishing to submit a director nomination should send a letter to the Board of Directors, c/o Corporate Secretary, Puma Biotechnology, Inc., 10880 Wilshire Boulevard, Suite 2150, Los Angeles, CA 90024. The mailing envelope must contain a clear notation indicating that the enclosed letter is a “Director Nominee Recommendation.” A stockholder that wishes to nominate a director candidate should submit complete information as to the identity and qualifications of the director candidate to the Nominating and Corporate Governance Committee, including all information that would be required to be disclosed about that person in a proxy statement relating to the election of directors. In making recommendations, stockholders should be mindful of the discussion of the minimum qualifications set forth above. Satisfaction of such minimum qualification standards does not imply that the Nominating and Corporate Governance Committee necessarily will nominate the person so recommended by a stockholder. With respect to deadlines and other matters relating to stockholder nominations of director candidates, see “Stockholder Proposals and Nominations.”

The members of our Nominating and Corporate Governance Committee are Mr. Moyes and Drs. Senderowicz and Wilson, with Mr. Moyes serving as the chair of the committee. The Board has determined that each of the members of our Nominating and Corporate Governance Committee are independent under the

applicable rules and regulations of the SEC and the NYSE. The Nominating and Corporate Governance Committee met three times during the fiscal year ended December 31, 2015.

Stock Option Committee

Our Stock Option Committee consists of Mr. Auerbach, a director and our President and Chief Executive Officer, serving as its sole member. The Board delegated to the Stock Option Committee the authority to grant stock options to non-executive employees, subject to the following conditions:

•

the maximum aggregate number of shares of common stock underlying options granted pursuant to this authority is 100,000 per individual, subject to adjustment by the Board; and

Legal Proceedings

We are not aware of any material proceedings in which any of our directors, executive officers or affiliates, any owner of record or beneficial owner of more than 5% of our common stock, or any associate of any such director, officer, affiliate or security holder is a party adverse to us or any of our subsidiaries or has a material interest adverse to us.

Code of Business Conduct and Ethics

We have adopted a code of business conduct and ethics that establishes the standards of ethical conduct applicable to all directors, officers and employees of our company. Our code of business conduct and ethics addresses, among other things, conflicts of interest, compliance with disclosure controls and procedures and internal control over financial reporting, corporate opportunities and confidentiality requirements. Our code of business conduct and ethics is available on our corporate website at www.pumabiotechnology.com/about_governance.html. We intend to disclose any future amendments to certain provisions of our code of business conduct and ethics, or waivers of provisions required to be disclosed under the rules of the SEC, at the same location on our website identified in the preceding sentence.

Corporate Governance Guidelines

We have adopted corporate governance guidelines and the guidelines are available on the Company’s corporate website at www.pumabiotechnology.com/about_governance.html.

Stockholders and other interested parties may send communications to the Company’s Board, including any individual director, any non-management director or the directors as a group, by mailing such communications to Puma Biotechnology, Inc., 10880 Wilshire Boulevard, Suite 2150, Los Angeles, CA 90024, Attention: Corporate Secretary. Such correspondence shall be addressed to the Board, any individual director or any non-management director by either name or title.

All communications received as set forth in the preceding paragraph will be opened by the Company’s Corporate Secretary for the sole purpose of determining whether the contents represent a message to the Company’s directors.

In the case of communications to the Board, any individual director or any non-management director, the Company’s Corporate Secretary will make sufficient copies of the contents to send to each director to which the envelope is addressed.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Executive Summary

The Compensation Committee of our Board develops our executive compensation policies and determines the amounts and elements of compensation for our named executive officers (“Named Executive Officers”).

We have in place a compensation strategy for our executives that we believe focuses on both individual and Company performance. Incentive compensation paid to our executives is awarded based on our Compensation Committee’s review of our achievement of near-term corporate targets and longer term business objectives and strategies. The Compensation Committee is responsible for evaluating and administrating all of our executive compensation programs and practices to ensure that they properly compensate, reward and drive corporate performance while remaining competitive with comparable biotechnology companies. The Compensation Committee reviews and approves all compensation for our executive officers, including base salaries, annual bonuses and equity incentive compensation.

This Compensation Discussion and Analysis describes our executive compensation programs for our Named Executive Officers for the 2015 fiscal year, who were:

•

Alan H. Auerbach, our President and Chief Executive Officer;

•

Charles R. Eyler, our Senior Vice President, Finance and Administration and Treasurer;

•

Richard P. Bryce, MBChB, MRCGP and MFPM, our Senior Vice President, Clinical Research and Development; and

•

Steven Lo, our Chief Commercial Officer.

Advisory Vote on Executive Compensation

At our 2015 annual meeting of stockholders, we held a say-on-pay vote, and the stockholders approved, on an advisory basis, the compensation of our Named Executive Officers, as disclosed in the proxy statement for that meeting pursuant to the compensation disclosure rules of the SEC. Upon review of the final voting results, and given the significant level of stockholder support (approximately 91% of the votes cast approved the say-on-pay proposal), we have not made any changes to our executive compensation policies or decisions as a result of the vote. In addition, at our 2012 annual meeting of stockholders, we held a say-on-frequency vote and our stockholders indicated their preference for three years as the frequency of future advisory votes on the compensation of our Named Executive Officers. Accordingly, our next say-on-pay vote will be held at our annual meeting in 2018.

Compensation Principles and Objectives

Our overall compensation program is structured to attract, motivate and retain highly qualified executive officers by paying them competitively, consistent with our success and their contribution to that success. Our ability to excel depends on the skill, creativity, integrity and teamwork of our employees. Given the long product development cycles in our business, we believe compensation should be structured to ensure that a portion of compensation opportunity will be related to factors that directly and indirectly influence long-term stockholder value. Our compensation philosophy has been driven by a number of factors that are closely linked with our broader strategic objectives.

The Compensation Committee believes that compensation paid to our Named Executive Officers should be aligned with our performance on both a short-term and long-term basis, linked to results intended to create value for stockholders, and that such compensation should assist us in attracting and retaining key executives critical to our long-term success.

In establishing compensation for executive officers, the following are the Compensation Committee’s objectives:

•

align officer and stockholder interests by providing a portion of total compensation opportunities for senior management in the form of equity awards and bonuses awarded based on the Compensation Committee’s review of company and individual performance;

•

ensure executive officer compensation is competitive within the marketplace in which we compete for executive talent by relying on the Compensation Committee’s judgment, expertise and personal experience with other similar companies, recognizing that because of the Company’s business model and relatively early stage of development, there may be few directly comparable companies; and

•

recognize that best compensation practices for a growing company may be substantially different than for a larger, more mature company and that we should make full use of our greater latitude and breadth of compensation opportunities.

Determination of Compensation

The Compensation Committee is charged with the primary authority to determine and recommend the compensation awards available to our executive officers for approval by the Board. Based on the Compensation Committee members’ collective understanding of compensation practices in similar companies in the biotechnology and pharmaceutical industry, our executive compensation package consists of the following elements, in addition to the employee benefit plans in which all employees may participate:

•

Base salary: compensation for ongoing services throughout the year.

•

Annual discretionary cash bonus awards: discretionary awards to recognize and reward achievement of corporate and individual performance.

•

Long-term equity incentive program: equity compensation to provide an incentive to our Named Executive Officers to manage us from the perspective of an owner with an equity stake in the business.

•

Severance and change in control benefits: remuneration paid to certain executives in the event of a qualifying termination of employment.

To aid the Compensation Committee in making its determination, our Chief Executive Officer provides recommendations annually to the Compensation Committee regarding the compensation of all other executive officers (other than himself) based on the overall corporate achievements during the period being assessed and his knowledge of the individual contributions to our success by each of the Named Executive Officers. The overall performance of our Named Executive Officers as a team is reviewed annually by the Compensation Committee.

We set base salary and annual bonus structures and any grants of stock options based on the Compensation Committee members’ collective understanding of compensation practices in the biotechnology and pharmaceutical industry and such members’ experiences as seasoned executives, consultants, board and Compensation Committee members, or investors in similar biotechnology and specialty pharmaceutical industry companies. In addition, from time to time we may rely on compensation survey data provided by Radford or other publicly-available datasets, such as from IBM or PayScale.

Elements of Executive Compensation

Base Salaries

Mr. Auerbach is the founder of our company, and accordingly his compensation was initially established to reflect his position as a founding executive and has evolved as we have grown. Mr. Eyler, Dr. Bryce and Mr. Lo joined us after we were founded, and their initial compensation was the result of arms-length negotiations at that time.

Base salaries of our Named Executive Officers (other than our Chief Executive Officer) are recommended and reviewed periodically by our Chief Executive Officer, and the base salary for each Named Executive Officer is approved by our Compensation Committee. Adjustments to base salaries are based on the scope of an executive’s responsibilities, individual contribution, experience and sustained performance. Decisions regarding salary increases may take into account the Named Executive Officer’s current salary, equity ownership and the amounts paid to individuals in comparable positions at our peer companies. No formulaic base salary increases are provided to our Named Executive Officers. This strategy is consistent with our intent of offering compensation that is cost-effective, competitive and contingent on the achievement of performance objectives.

In 2015, the Compensation Committee approved base salary increases for Messrs. Auerbach and Eyler, each effective September 1, 2015, and Dr. Bryce, effective June 20, 2015. The following table shows these executives’ annual base salary prior to and after the increases.


Name	Prior Annual Base Salary ($)		New Annual Base Salary ($)
Alan H. Auerbach		630,000		693,000
Charles R. Eyler		333,108		372,600
Richard P. Bryce, MBChB, MRCGP, MFPM		357,210		385,787

The Compensation Committee determined to approve these base salary increases to reward the executives for their significant contributions to the development of the Company, as well as to bring their salaries in line with competitive positions (as determined based on the Compensation Committee’s review of the various compensation survey data mentioned above).

The actual base salaries paid to all of our Named Executive Officers during 2015 are set forth in the “Summary Compensation Table” below.

Bonuses

Annual Bonuses. Cash bonuses are intended to provide incentives to drive company-wide performance. Each of our Named Executive Officers is eligible to receive a discretionary cash bonus targeted as a percentage of the executive’s base salary. For 2015, Messrs. Auerbach, Eyler and Lo, and Dr. Bryce were eligible to receive a discretionary cash bonus targeted at 50%, 35%, 40% and 35%, respectively, of their annual base salary (and for Messrs. Auerbach and Eyler, and Dr. Bryce, prior to the 2015 increases).

The determination of the amount of annual bonuses paid to our Named Executive Officers generally reflects a number of considerations by the Compensation Committee acting in their discretion, including, among other things, the performance of the Company and a subjective evaluation of the individual contribution and performance of each Named Executive Officer. Bonus determinations are not formulaic and no particular weight is assigned to any of the factors considered by the Compensation Committee.

In 2015, in accordance with the approach described above, the Compensation Committee awarded cash bonuses of $315,000 to Mr. Auerbach, $134,076 to Mr. Eyler and $161,141 to Dr. Bryce, which represents approximately 50%, 40%, and 40%, respectively, of the executive’s annual base salary, and for Messrs. Auerbach and Eyler, and Dr. Bryce, prior to the 2015 increases.

Signing Bonus. In connection with entering into his employment offer letter, we paid to Mr. Lo a one-time signing bonus equal to $1,051,249. This bonus will not be earned in full until the fourth anniversary of Mr. Lo’s hire date, and is repayable, in part or in full, if his employment is terminated either by the Company for cause or by Mr. Lo for any reason, in either case prior to the fourth anniversary of his hire date.

Equity Awards

The goals of our long-term, equity-based incentive awards are to align the interests of our Named Executive Officers with the interests of our stockholders. Because vesting is based on continued service, our equity-based incentives also encourage the retention of our Named Executive Officers during the award vesting period. In determining the size of the long-term equity incentives to be awarded to our Named Executive Officers, we take into account a number of factors, such as the relative job scope, the value of existing stockholdings and long-term incentive awards, individual performance history, prior financial contributions to us and the size of prior grants.

To reward and retain our Named Executive Officers in a manner that aligns their interests with stockholders’ interests, we have historically used stock options as the primary incentive vehicle for long-term compensation. Because employees realize value from stock options only if our stock price increases relative to the stock option’s exercise price, we believe stock options provide meaningful incentives to achieve increases in the value of our stock over time.

We generally use stock options to compensate our Named Executive Officers both in the form of initial grants in connection with the commencement of employment and additional or “refresher” grants. We have not established a formula or program for determining the size of any equity award, including any annual refresher grants, and our Compensation Committee retains discretion to make stock option awards to employees at any time, including in connection with the promotion of an employee, to reward an employee, for retention purposes or in other circumstances recommended by management.

The exercise price of each stock option grant is at or above the fair market value of our common stock on the grant date, for which we use the closing price of our common stock on the grant date. Stock option awards typically vest over a three-year period as follows (subject to continued service through the applicable vesting date): one-third of the shares underlying the option vest on the first anniversary of the vesting commencement date, and the remainder of the shares underlying the option vest in equal monthly installments over the following 24 months. However, in connection with entering into an employment offer letter with Mr. Lo, we granted him an option covering 150,000 shares that vests over a four-year period, with the 25% vesting on the first anniversary of his employment commencement date and the remainder vesting in substantially equal monthly installments thereafter, subject to his continued employment. We believe these vesting schedules appropriately encourage continued service with the Company while allowing our executives to realize compensation in line with the value they have created for our stockholders.

During 2015, we made the following grants of stock options to our Named Executive Officers. The options vest in accordance with the vesting schedules described above.


Name	2015 Stock Option Grants (# of Shares)
Alan H. Auerbach		150,000
Charles R. Eyler		31,500
Richard P. Bryce, MBChB, MRCGP, MFPM		31,500
Steven Lo		150,000

As a result of our Compensation Committee’s assessment of our Chief Executive Officer’s substantial roles and responsibilities within the Company, our Compensation Committee determined it was appropriate for Mr. Auerbach to receive a larger stock option grant than those of our other Named Executive Officers. In addition, the size of Mr. Lo’s 2015 option grant was larger as it was negotiated as part of his initial hiring compensation package.

Severance and Change in Control Arrangements

Mr. Auerbach’s and Mr. Lo’s employment agreements provide that the executive is eligible to receive severance payments and benefits upon a qualifying involuntary termination of employment, including in

connection with a change in control of our company. We believe that these protections serve to encourage continued attention and dedication to duties without distraction arising from the possibility of a change in control, and provide the business with a smooth transition in the event of such a termination of employment in connection with a transaction. These severance and change in control arrangements are designed to retain certain of our executives in these key positions as we compete for talented executives in the marketplace where such protections are commonly offered. For a detailed description of the severance provisions contained in Mr. Auerbach’s and Mr. Lo’s employment agreements, see “Potential Payments Upon Termination or Change in Control” below.

In addition, Mr. Lo’s employment agreement provides he is eligible to receive severance payments and benefits upon a qualifying termination, including in connection with a change in control of our company. For a detailed description of the severance provisions contained in Mr. Lo’s employment agreement, see “Potential Payments Upon Termination or Change in Control” below.

Other Elements of Compensation and Perquisites

All of our full-time employees in the United States, including our Named Executive Officers, are eligible to participate in our 401(k) plan. Pursuant to our 401(k) plan, employees may elect to reduce their current compensation by up to the statutorily prescribed annual limit, which was $18,000 in 2015, and to have the amount of this reduction contributed to our 401(k) plan. In addition, all of our full-time employees, including our Named Executive Officers, are eligible to participate in our health and welfare plans.

Tax and Accounting Considerations

Section 162(m) of the Code

Section 162(m) of the Code disallows a tax deduction for any publicly held corporation for individual compensation exceeding $1.0 million in any taxable year for the group of individuals generally comprised of its named executive officers, other than its chief financial officer, unless compensation is performance-based. Where reasonably practicable and to the extent that the Section 162(m) deduction disallowance becomes applicable to our company, our Compensation Committee may seek to qualify the variable compensation paid to our executive officers for an exemption from the deductibility limitations. As such, in approving the amount and form of compensation for our executive officers in the future, our Compensation Committee has and will continue to consider all elements of the cost to our company of providing such compensation, including the potential impact of Section 162(m) of the Code. However, our Compensation Committee may, in its judgment, authorize compensation payments that do not comply with the exemptions in Section 162(m) of the Code when it believes that such payments are appropriate to attract and retain executive talent.

Section 280G of the Code

Section 280G of the Code disallows a tax deduction with respect to excess parachute payments to certain executives of companies which undergo a change in control. In addition, Section 4999 of the Code imposes a 20% excise tax on the individual with respect to the excess parachute payment. Parachute payments are compensation linked to or triggered by a change in control and may include, but are not limited to, bonus payments, severance payments, certain fringe benefits, and payments and acceleration of vesting from long-term incentive plans including stock options and other equity-based compensation. Excess parachute payments are parachute payments that exceed a threshold determined under Section 280G of the Code based on the executive’s prior compensation. In approving the compensation arrangements for our named executive officers in the future, our Compensation Committee will consider all elements of the cost to the Company of providing such compensation, including the potential impact of Section 280G of the Code. However, our Compensation Committee may, in its judgment, authorize compensation arrangements that could give rise to loss of deductibility under Section 280G of the Code and the imposition of excise taxes under Section 4999 of the Code when it believes that such arrangements are appropriate to attract and retain executive talent.

Under his employment agreement, Mr. Auerbach may be entitled to a gross-up payment that will make him whole in the event that any parachute payment excise taxes are imposed on him in excess of a certain threshold. We provide this protection to Mr. Auerbach to help ensure that he will be properly incentivized in the event of a potential change in control of the Company to maximize shareholder value in a transaction without concern for potential consequences of the transaction to him.

Accounting Standards

ASC Topic 718, Compensation – Stock Compensation (“ASC Topic 718”) requires us to recognize an expense for the fair value of equity-based compensation awards. Grants of stock options, restricted stock, performance shares and restricted stock units (“RSUs”) under our equity incentive award plans are accounted for under ASC Topic 718. Our Compensation Committee regularly considers the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity incentive award plans and programs. As accounting standards change, we may revise certain programs to appropriately align accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

Potential Payments Upon a Termination or Change in Control

Alan H. Auerbach. On January 19, 2012, we entered into an employment agreement with Alan H. Auerbach, our President and Chief Executive Officer. Pursuant to the employment agreement, in the event Mr. Auerbach’s employment is terminated by us without “cause” or by Mr. Auerbach for “good reason” 60 days prior to, or 18 months following, a “change in control” (each as defined in the employment agreement and described below), he will be entitled to receive, in addition to any accrued but unpaid compensation and benefits:

•

a lump sum payment equal to two times the sum of his base salary and the maximum bonus to which he would be eligible to receive for the year in which the termination occurs;

•

all unvested equity-based incentive awards will immediately vest on the later of the change in control and the termination date, and will remain exercisable (as applicable) for a period of up to 12 months from the date of the termination; and

•

up to 18 months continuation of healthcare benefits to him and his dependents.

In the event a change in control occurs and an excise tax is imposed as a result of any payments made to Mr. Auerbach in connection with such change in control, we will either (i) reduce the payments made to Mr. Auerbach such that the excise tax will not be imposed or (ii) in certain circumstances, pay the entire (unreduced) payments and also pay or reimburse Mr. Auerbach an amount equal to any such excise tax plus any taxes resulting from such payments.

In the event Mr. Auerbach’s employment is terminated without “cause” or by Mr. Auerbach for “good reason,” in each case outside of the change in control context described above, then Mr. Auerbach will be entitled to receive, in addition to any accrued but unpaid compensation and benefits (i) an amount equal to the sum of his base salary and the maximum bonus to which he would be eligible to receive for the year in which the termination occurs, payable over a period of one year following such termination in substantially equal installments; and (ii) up to 18 months continuation of healthcare benefits to him and his dependents. All severance benefits are contingent upon Mr. Auerbach’s execution and non-revocation of a general release of claims in favor of us. Under the terms of Mr. Auerbach’s employment agreement:

•

“Cause” is generally defined as (i) the willful failure, disregard or refusal by the executive to perform his duties; (ii) any willful, intentional or grossly negligent act by the executive that injures in a material way our business or reputation; (iii) willful misconduct by the executive in respect of his duties or obligations; (iv) the executive’s commission of any felony or a misdemeanor involving moral turpitude (including entry of a nolo contendere plea to any such charge); (v) the determination by us, after a reasonable and good-faith investigation following a written allegation by another employee of us that the executive engaged in some form of harassment prohibited by law, unless the executive’s actions were specifically directed by the board; (vi) any misappropriation or embezzlement of our property; (vii) breach by the executive of his obligations with respect to confidentiality, non-solicitation and non-disparagement or of any of his representations or warranties under the employment agreement; and (viii) material breach by the executive of any other provision of the employment agreement which is not cured within a specified timeframe.

•

“Good reason” is generally defined as: (i) a material diminution in the executive’s base salary, excluding any reduction applicable equally to all of our executive officers following a material decline in our earnings, public image, or performance; (ii) a material diminution in the executive’s authority,

duties or responsibilities; (iii) a change in the geographic location at which the executive must perform services to a location that is greater than 25 miles from our principal place of business as of the date of the employment agreement; (iv) a direction to the executive to take any action that violates any applicable legal or regulatory requirement; or (v) any other action or inaction that constitutes a material breach by us of our obligations under the employment agreement.

•

A “change in control” is generally defined as: (i) the consummation of a transaction where any persons become the beneficial owners of Company securities representing more than 50% of the total combined voting power of our securities after such acquisition; (ii) a change in the composition of the board such that during any period of two consecutive years, individuals who originally formed our Board, together with certain new directors, at the beginning of such period cease for any reason to constitute a majority of the board; (iii) us merging, consolidating, reorganizing or combining with another corporation or entity or a sale or other disposition of all or substantially all of our assets or an acquisition of assets or stock of another entity, in each case, where our stockholders prior to the transaction own less than 50% of the outstanding voting securities of the surviving corporation or entity; or (iv) our stockholders approving a liquidation or dissolution of us.

Steven Lo. On August 17, 2015, we entered into an employment letter agreement with Steven Lo, our Chief Commercial Officer. Pursuant to the letter agreement, in the event Mr. Lo’s employment is terminated by us without “cause” or by Mr. Lo for “good reason” (each as defined in the letter agreement and described below) he will be entitled to receive, in addition to any accrued but unpaid compensation and benefits (i) 12 months base salary, to be paid in substantially equal installments in accordance with the Company’s standard payroll policies; (ii) up to 12 months continuation of healthcare benefits to him and his dependents; and (iii) if the termination occurs on or within the 18 months following a “change in control” (as defined in the letter agreement and described below) all unvested equity-based incentive awards will immediately vest on the termination date. All severance benefits are contingent upon Mr. Lo’s execution and non-revocation of a general release of claims in favor of us. Under the terms of Mr. Lo’s employment agreement:

•

“Cause” is generally defined as (i) the unauthorized use or disclosure of confidential information or trade secrets of the Company or any other material breach of a written agreement between the executive and the Company, including without limitation a material breach of any employment or confidentiality agreement; (ii) the executive’s indictment for, or the entry of a plea of guilty or nolo contendere by the executive to, a felony under the laws of the United States or any state thereof or other foreign jurisdiction or any crime involving dishonesty or moral turpitude; (iii) the executive’s gross negligence or willful misconduct or the executive’s willful or repeated failure or refusal to substantially perform assigned duties; (iv) any act of fraud, embezzlement, material misappropriation or dishonesty committed by the executive against the Company; or (v) any acts, omissions or statements by an executive which the Company reasonably determines to be materially detrimental or damaging to the reputation, operations, prospects or business relations of the Company.

•

“Good reason” is generally defined as (i) a material diminution in the executive’s base salary, excluding any reduction applicable equally to all of our executive officers following a material decline in our earnings, public image, or performance; (ii) a material diminution in the executive’s authority, duties or responsibilities; and (iii) a change in the geographic location at which the executive must perform services to a location that is greater than 25 miles from our principal place of business as of the date of the employment agreement.

•

stock of another entity, in each case, where our stockholders prior to the transaction own less than 50% of the outstanding voting securities of the surviving corporation or entity; or (iv) our stockholders approving a liquidation or dissolution of us.

Charles R. Eyler and Richard P. Bryce, MBChB, MRCGP, MFPM. None of our other Named Executive Officers are entitled to any payments from us following, or in connection with such Named Executive Officer’s resignation, retirement or other termination, or a change in control of us or a change in such Named Executive Officer’s responsibilities following a change in control, except that, under the terms of the Plan, in the event of a change in control (as defined above), if the successor corporation refuses to assume or substitute any equity award held by Mr. Eyler or Dr. Bryce, such equity awards will immediately vest and, if applicable, become exercisable and be deemed exercised immediately prior to the change in control transaction.

Responsibilities. The Audit Committee operates under a written charter adopted by the Board. The role of the Audit Committee is to oversee the Company’s financial reporting process on behalf of the Board. The Company’s management has the primary responsibility for the Company’s financial statements as well as its financial reporting process and principles, internal controls and disclosure controls. Management is responsible for the preparation, presentation and integrity of the Company’s financial statements.

Management is also responsible for establishing and maintaining disclosure controls (as defined in Exchange Act Rule 13a-15(e)) and for evaluating the effectiveness of disclosure controls and procedures. The independent registered public accounting firm, PKF Certified Public Accountants, are responsible for performing an audit of the Company’s financial statements and expressing an opinion as to the conformity of such financial statements with U.S. generally accepted accounting principles and are also responsible for expressing an opinion on the effectiveness of the Company’s internal controls over financial reporting.

Pre-Approval Policies and Procedures

For the fiscal years ended December 31, 2015 and 2014, our Audit Committee approved the audit-related and non-audit related services performed by PKF Certified Public Accountants and associated fees. The Audit Committee determined that the rendering of the non-audit services was compatible with maintaining the independence of PKF Certified Public Accountants.

For the fiscal year ending December 31, 2016, our Audit Committee pre-approved audit-related and non-audit related services not prohibited by law to be performed by our independent registered public accountants and estimated fees. Audit Committee pre-approval of audit and non-audit services will not be required if the engagement for the services is entered into pursuant to pre-approval policies and procedures established by the Audit Committee regarding our engagement of the independent auditor, provided the policies and procedures are detailed as to the particular service, the Audit Committee is informed of each service provided and such policies and procedures do not include delegation of the Audit Committee’s responsibilities to our management. The

Audit Committee may delegate to one or more designated members of the Audit Committee the authority to grant pre-approvals, provided such approvals are presented to the Audit Committee at a subsequent meeting. If the Audit Committee elects to establish pre-approval policies and procedures regarding non-audit services, the Audit Committee must be informed of each non-audit service provided by the independent auditor. Audit committee pre-approval of non-audit services (other than review and attestation services) also will not be required if such services fall within available exceptions established by the SEC.

PROPOSAL 2

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Background

The Audit Committee of our Board has selected PKF Certified Public Accountants, a Professional Corporation, as our independent registered public accountants for the year ending December 31, 2016, and has further directed that management submit the selection of independent registered public accountants for ratification by the stockholders at the annual meeting. A representative of PKF Certified Public Accountants is expected to be present at the annual meeting and will have an opportunity to make a statement if he or she so desires and will be available to respond to appropriate questions.

If the stockholders fail to ratify the selection of PKF Certified Public Accountants as our independent registered public accountants for the year ending December 31, 2016, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of us and our stockholders.

Board Recommendation

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE RATIFICATION OF PKF CERTIFIED PUBLIC ACCOUNTANTS, A PROFESSIONAL CORPORATION, AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2016.

INTRODUCTORY NOTE FOR PROPOSALS 3 AND 4

If Proposal 3 or 4 amending our current Certificate of Incorporation is approved, the Company will file a Second Amended and Restated Certificate of Incorporation (“Second Amended and Restated Certificate of Incorporation”), which will incorporate into one document our current Certificate of Incorporation and only the amendments approved by the stockholders at the annual meeting. The Second Amended and Restated Certificate of Incorporation will not incorporate any changes that are not independently approved by the stockholders. The text of the proposed Second Amended and Restated Certificate of Incorporation that is attached to this Proxy Statement as Appendix A incorporates all of the amendments contemplated by Proposals 3 and 4. If any of the amendments set forth in Proposal 3 or 4 are approved by the stockholders, the proposed changes to page A-1 of Appendix 1 will be made along with the changes that correspond to the proposals that were approved by the stockholders. For ease of reference, Exhibit A of Appendix A shows the new sections and changes related to the proposed amendments, and the footnotes in Exhibit A of Appendix A explain which proposed amendments relate to which proposal. We are submitting Proposals 3 and 4 to the stockholders as separate proposals so that our stockholders are able to express their views on each proposed amendment separately. None of Proposal 3 and 4 is conditioned on the approval of any other proposal. At any time prior to the effectiveness of the filing of the Second Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, notwithstanding the authorization of any or all of the proposed amendments by the stockholders, the Board may abandon any or all of the proposed amendments without further action by the stockholders.

PROPOSAL 3

APPROVAL OF AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO ELIMINATE THE ABILITY OF STOCKHOLDERS TO ACT BY WRITTEN CONSENT

On April 14, 2016, our Board approved and recommended that the stockholders adopt a proposal to amend and restate our Certificate of Incorporation to eliminate the ability of stockholders to act by written consent.

Section 228 of the General Corporation Law of the State of Delaware provides that, unless otherwise provided in a company’s certificate of incorporation, any action that may be taken at any annual or special meeting of stockholders may be taken without a meeting, without prior notice to all stockholders and without holding a vote, if a consent in writing is signed by stockholders representing the minimum number of votes necessary to approve the action at a meeting at which all shares entitled to vote thereon were present and voted. The Company’s stockholders currently have the ability to act by written consent because the Company’s existing Certificate of Incorporation does not contain a provision eliminating the right of stockholders to act by written consent. If our stockholders adopt this proposed amendment to the Certificate of Incorporation, the power of our stockholders to act without a meeting by written consent will be eliminated. Our Board has determined that removing the ability of the stockholders to act by written consent without a meeting is in the best interests of the stockholders.

Our Board values the exchange of thoughts and views with all of our stockholders, is committed to being highly responsive to stockholder interests and concerns and has carefully considered the advantages and disadvantages of eliminating the ability of stockholders to act by written consent and has determined that it is appropriate to adopt this proposed amendment to our Certificate of Incorporation. In particular, the Board has noted that the written consent process, by its nature, is not conducive to an orderly and transparent discussion on the merits of a proposed action, as would occur if the action were raised at a meeting of stockholders. Even if we eliminate the ability of our stockholders to act by written consent, proposals for stockholder action, such as proposed amendments to our Bylaws or the removal of one or more of our directors, could still take place at our annual meeting of stockholders. The process for proposing and discussing matters at an annual meeting is well-established and specifically designed to provide stockholders and the Board adequate time to review, evaluate, discuss and consider a proposed action. The written consent process does not foster these characteristics and can be subject to abuse. For example, a dissident stockholder holding less than 1% of the Company’s outstanding common stock recently launched an unsolicited consent solicitation to elect himself and his three other nominees to the Board. Because our Certificate of Incorporation permitted stockholders to take action by written consent, this dissident stockholder was able to commence this process without ever approaching the Company or the Board to express any concerns or ideas. In fact, even when given the opportunity to meet with our Chief Executive Officer, the stockholder refused and continued with this hostile attack on the Board. The consent solicitation resulted in an expensive and time-consuming distraction to the Company’s operational efforts during a critical time in the Company’s development. Moreover, only approximately 0.8% of the Company’s outstanding shares of common stock, which included the 0.5% held by the dissident himself, supported the dissident’s proposals. The consent solicitation cost the Company over a million dollars and resulted in an unnecessary distraction of management’s time and in two litigation matters that are ongoing.

The proposed amendment also provides various additional benefits. For example, the amendment could reduce the time and effort our Board and management would need to devote to stockholder proposals, which time and effort could distract our directors and management from other important company business. In addition, the amendment would make it difficult for a person who acquires a majority of the outstanding common stock of the Company to approve a merger or sale of the Company or take other action normally requiring a vote of stockholders without providing notice to all stockholders and convening a meeting to vote on the proposed action. The Board believes that the benefits of discouraging hostile bidders and dissident stockholders seeking to further their own special interests from conducting potentially expensive and disruptive consent solicitations outweigh the inconvenience of needing to act at our annual meeting of stockholders.

In light of the foregoing, the Board believes that amending its Certificate of Incorporation to eliminate stockholder action by written consent is a prudent corporate governance measure. The proposed text relating to the amendment to the Company’s Certificate of Incorporation to eliminate the ability of stockholders to act by written consent as it is proposed to be amended is included in Article 6 of the form of the Second Amended and Restated Certificate of Incorporation that is attached to this Proxy Statement as Appendix A.

If stockholders approve this proposal, the Board will approve corresponding amendments to the Company’s Bylaws.

Required Vote

Approval of this amendment requires the receipt of the affirmative vote of a majority of the shares of the Company’s common stock issued and outstanding as of the record date. If approved, the amendment will become effective upon filing with the Secretary of State of the State of Delaware of the Second Amended and Restated Certificate of Incorporation, which the Company intends to do promptly following the annual meeting.

Board Recommendation

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE AMENDMENT TO THE COMPANY’S CERTIFICATE OF INCORPORATION TO ELIMINATE THE ABILITY OF STOCKHOLDERS TO ACT BY WRITTEN CONSENT.

PROPOSAL 4

APPROVAL OF AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO ELIMINATE THE MANDATORY INDEMNIFICATION OF ALL PERSONS COVERED BY SECTION 145 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

On April 14, 2016, our Board approved and recommended that the stockholders adopt a proposal to amend and restate our Certificate of Incorporation to eliminate the mandatory indemnification of all persons covered by Section 145 of the General Corporation Law of the State of Delaware (“Section 145”) (the “Mandatory Indemnification Elimination Amendment”).

Article 8 of our Certificate of Incorporation currently requires that the Company indemnify, to the fullest extent permitted under Section 145, as amended from time to time, each person that Section 145 grants the Company the power to indemnify. This provision requires mandatory indemnification of all individuals serving as employees and agents of the Company. Under the proposed amendment, this mandatory indemnification requirement would be eliminated from our Certificate of Incorporation. The Board believes this type of mandatory indemnification is not appropriate because it imposes overly broad obligations on the Company that limit its ability to act in the best interests of its stockholders. For example, there are circumstances where indemnification may not be appropriate, such as for lawsuits brought against the Company by an individual that the Company might be required to indemnify. Moreover, there are certain individuals, such as various consultants and agents, that the Company should not be required to indemnify because those parties have already agreed to assume certain costs and liabilities associated with their services. The amendment is not being proposed in response to any specific indemnification claim or matter.

The Board believes that it would be in the best interests of the Company and its stockholders to give the Board the flexibility to determine on a case-by-case basis whether non-executive employees or agents of the Company should be entitled to be indemnified by the Company, rather than requiring such indemnification for all non-executive employees and agents in its certificate of incorporation. The Company’s Bylaws still provide for the mandatory indemnification of our directors and officers. Moreover, under Section 145, the Board would still be permitted to allow the Company to indemnify non-executive employees and agents as determined by the Board from time to time to the extent permitted by Section 145. Additionally, the elimination of this mandatory indemnification would bring the Company’s indemnification practices in line with current market practice. For these reasons, the Board believes that the Company’s Certificate of Incorporation should be amended to eliminate the mandatory indemnification of all persons that Section 145 grants the Company the power to indemnify.

If approved, the provisions of Article 8 of the current Certificate of Incorporation would be deleted as proposed in the Second Amended and Restated Certificate of Incorporation that is attached to this Proxy Statement as Appendix A, with deletions indicated by strikeouts.

Required Vote

Approval of the Mandatory Indemnification Elimination Amendment requires the receipt of the affirmative vote of a majority of the shares of the Company’s common stock issued and outstanding as of the record date. If approved, the amendment will become effective upon filing of the Second Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, which the Company intends to do promptly following the annual meeting.

Board Recommendation

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE AMENDMENT TO THE COMPANY’S CERTIFICATE OF INCORPORATION TO ELIMINATE THE MANDATORY INDEMNIFICATION OF ALL PERSONS COVERED BY SECTION 145 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE.

OTHER MATTERS

Policies and Procedures for Review, Approval or Ratification of Transactions with Related Persons

Under our written Related Party Transactions Policy and Procedures, a related party transaction (as defined below) may be consummated or may continue only if the Audit Committee of our Board approves or ratifies the transaction in accordance with the guidelines set forth in the policy and if the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party. If advance Audit Committee approval of a related party transaction requiring the Audit Committee’s approval is not practicable, a related party transaction may be preliminarily entered into by management subject to ratification of the transaction by the Audit Committee; provided that if ratification is not forthcoming, management shall make all reasonable efforts to cancel or annul such transaction. Management shall update the Audit Committee as to any material changes to any approved or ratified related party transaction and shall provide a status report at least annually at a regularly scheduled meeting of the Audit Committee of all then current related party transactions.

For the purposes of our policy, a “related party transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which the Company (including any of its subsidiaries) was, is or will be a participant and the amount involved exceeds $120,000, and in which any related party (as defined below) had, has or will have a direct or indirect interest. A “related party” includes (i) any person who is, or at any time since the beginning of the Company’s last fiscal year was, a director or executive officer of the Company or a nominee to become a director of the Company; (ii) any person who is known to be the beneficial owner of more than 5% of any class of the Company’s voting securities; (iii) any immediate family member of any of the foregoing persons, which means 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 the director, executive officer, nominee or more than 5% beneficial owner, and any person (other than a tenant or employee) sharing the household of such director, executive officer, nominee or more than 5% beneficial owner; and (iv) any firm, corporation or other entity in which any of the foregoing persons is employed or is a general partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors and officers, and persons who beneficially own more than ten percent (10%) of our Common Stock, who are hereinafter collectively referred to as the Reporting Persons, to file with the SEC reports of beneficial ownership and reports of changes in beneficial ownership of our Common Stock on Forms 3, 4 and 5. Reporting Persons are required by applicable SEC rules to furnish us with copies of all such forms filed with the SEC pursuant to Section 16(a) of the Exchange Act. To our knowledge, based solely on our review of the copies of the Forms 3, 4 and 5 received by us during the fiscal years ended December 31, 2015 and 2014 and written representations that no other reports were required, we believe that all reports required to be filed by such persons with respect to the Company’s fiscal years ended December 31, 2015 and 2014 were timely filed, except that Richard P. Bryce, our Senior Vice President, Clinical Research and Development, filed late a Form 4, reporting two transactions involving the purchase of a total of 30 shares.

Stockholder Proposals and Nominations

Proposals Pursuant to Rule 14a-8. Pursuant to Rule 14a-8 under the Exchange Act, stockholders may present proper proposals for inclusion in the proxy statement and for consideration at our next annual meeting of stockholders. To be eligible for inclusion in the 2017 proxy statement, your proposal must be received by us no later than December 30, 2016, and must otherwise comply with Rule 14a-8. While our Board will consider stockholder proposals, we reserve the right to omit from the proxy statement stockholder proposals that we are not required to include under the Exchange Act, including Rule 14a-8.

Proposals and Nominations Pursuant to Our Amended and Restated Bylaws. Under our Bylaws and based on the anniversary date of the 2016 annual meeting as currently scheduled, in order to nominate a director or bring any other business before the stockholders at our next annual meeting of stockholders that will not be included in our proxy statement, you must notify us in writing and such notice must be received by us no earlier than February 13, 2017 and no later than March 15, 2017. In the event the annual meeting is convened on a date more than 30 days before or more than 60 days after such anniversary date, such notice must be received not earlier than the 120th day prior to such annual meeting nor later than the 90th day prior to such annual meeting or, if later, the 10th day following the day on which public disclosure of the date of the annual meeting was first made. For proposals not made in accordance with Rule 14a-8, you must comply with specific procedures set forth in our Bylaws and the nomination or proposal must contain the specific information required by our Bylaws. You may write to our Corporate Secretary at our principal executive offices, Puma Biotechnology, Inc., 10880 Wilshire Boulevard, Suite 2150, Los Angeles, CA 90024, Attention: Corporate Secretary, to deliver the notices discussed above and to request a copy of the relevant bylaw provisions regarding the requirements for making stockholder proposals and nominating director candidates under our Bylaws.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (such as banks and brokers) to satisfy the delivery requirements for notices of annual meetings, proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies. This year, a single notice of the annual meeting of stockholders, or copy of the proxy statement and annual report, will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your bank or broker that it will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, please notify your bank or broker, direct your written request to Puma Biotechnology, Inc., 10880 Wilshire Boulevard, Suite 2150, Los Angeles, CA 90024, Attention: Investor Relations, or contact Investor Relations by telephone at (424) 248-6500. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request householding of their communications should contact their bank or broker.

Incorporation by Reference

Notwithstanding anything to the contrary set forth in any of our previous filings under the Securities Act or the Exchange Act, which might incorporate future filings made by us under those statutes, the Compensation Committee Report and the Audit Committee Report will not be incorporated by reference into any of those prior filings, nor will the reports be incorporated by reference into any future filings made by us under those statutes. In addition, information on our website, other than our Annual Report, proxy statement, notice and form of proxy, is not part of the proxy soliciting material and is not incorporated herein by reference.

Other Business

As of the date of this proxy statement, the Board knows of no other business that will be presented for consideration at the 2016 annual meeting. If other proper matters are presented at the 2016 annual meeting, however, it is the intention of the proxy holders named in the Company’s form of proxy to vote the proxies held by them in accordance with their best judgment.
