Table of Contents

Broker non-votes occur when shares are held indirectly through a broker, bank or other nominee or intermediary on behalf of a beneficial owner (referred to as held in 'street name') and the broker submits a proxy but does not vote for a matter because the broker has not received voting instructions from the beneficial owner and (i) the broker does not have discretionary voting authority on the matter or (ii) the broker chooses not to vote on a matter for which it has discretionary voting authority. Pursuant to the New York Stock Exchange, which govern voting matters at the Annual Meeting, brokers are permitted to exercise discretionary voting authority only on 'routine' matters when voting instructions have not been timely received from a beneficial owner.

The following matters up for vote at the Annual Meeting are considered to be 'routine': (i) the amendment to our Certificate of Incorporation, and (ii) the ratification KPMG LLP as our independent registered public accounting firm for the year ending December 31, 2021. Brokers that hold your shares, therefore, have discretionary authority to vote your shares on these matters unless they receive instructions from you on these matters.

Q:What constitutes a quorum at the Annual Meeting?

If a quorum is not present at the Annual Meeting, a majority of the stockholders present virtually in person and by proxy may adjourn the meeting to another date. If an adjournment is for more than 30 days or a new record date is fixed for the adjourned meeting by our Board, we will provide notice of the adjourned meeting to each stockholder of record entitled to vote at the adjourned meeting. At any adjourned meeting at which a quorum is present, any business may be transacted that might have been transacted at the originally called Annual Meeting.

CORPORATE GOVERNANCE

Our Board of Directors

Our Bylaws provide that the Board shall consist of one or more members, as determined from time to time by resolution of the Board. Currently, our Board consists of seven members. The following individuals are being nominated to serve on our Board (See 'Proposal 1 - Election of Directors; Nominees'):

​

The Board does not have a formal policy regarding the separation of the roles of Chief Executive Officer and Executive Chairman, as the Board believes that it is in the best interests of the Company to make that determination based on the direction of the Company and the current membership of the Board. The Board has determined that having a director who is an executive officer serve as the Chairman is in the best interest of the Company's stockholders at this time. Although the Company plans to retain Mr. Weiss as Executive Chairman and Chief Executive Officer, the Company plans on appointing a Lead Independent Director after the Annual Meeting. The Lead Independent Director will be responsible for presiding at regular executive sessions of the independent directors, lead annual independent director evaluations of the Chairman and Chief Executive Officer, and serve as a liaison between the Chairman and Chief Executive Officer and the independent directors.

TG has a risk management program overseen by Michael S. Weiss, our Executive Chairman, Chief Executive Officer and President, and the Board. Mr. Weiss and management identify material risks and prioritize them for our Board. Our Board regularly reviews information regarding our credit, liquidity, operations, and compliance as well as the risks associated with each.

The following biographies set forth the names of our directors and director nominees, their ages, the year in which they first became directors, their positions with us, their principal occupations and employers for at least the past five years, any other directorships held by them during the past five years in companies that are subject to the reporting requirements of the Securities Exchange Act of 1934 (the 'Exchange Act'), or any company registered as an investment company under the Investment Company Act of 1940, as well as additional information, all of which we believe sets forth each director nominee's qualifications to serve on the Board. There is no family relationship between and among any of our executive officers or directors. There are no arrangements or understandings between any of our executive officers or directors and any other person pursuant to which any of them are elected as an officer or director, except as disclosed below.

On December 29, 2011, Opus Point Partners, LLC, ('Opus'), TG Biologics, Inc. ('TG Biologics') and the Company (and collectively with Opus and TG Biologics, the 'Parties') entered into an Exchange Transaction Agreement (the 'Agreement'). On August 2, 2012, the Parties executed an amendment to the Agreement ('Amendment No. 1') which set the number of members of the board of directors of the Company (the 'Board of Directors') at six and required the consent of Opus for any increase. Opus has consented to the increase to seven. Amendment No. 1 also granted Opus the right to nominate up to three members of the Board of Directors until the later of (x) two years from the Closing Date of the Agreement (as defined therein), or (y) the date on which Opus beneficially owns less than 10% of the Company's common stock as calculated pursuant to the rules and regulations under Section 13 of the Exchange Act. As of December 31, 2020 Opus owned less than 10% of the Company's common stock.

TG adheres to the corporate governance standards adopted by The Nasdaq Stock Market ('Nasdaq'). Nasdaq rules require our Board to make an affirmative determination as to the independence of each director. Consistent with

5

Table of Contents

these rules, our Board undertook its annual review of director independence on April 15, 2021. During the review, our Board considered relationships and transactions during 2020 and during the past three fiscal years between each director or any member of his immediate family, on the one hand, and the Company and our subsidiaries and affiliates, on the other hand. The purpose of this review was to determine whether any such relationships or transactions were inconsistent with a determination that the director is independent. Based on this review, our Board determined that Yann Echelard, Laurence Charney, William Kennedy, Kenneth Hoberman, Daniel Hume and Dr. Sagar Lonial are independent under the criteria established by Nasdaq and our Board.

Michael S. Weiss, 55, has served as TG's Executive Chairman, President and CEO since December 2011. Mr. Weiss is also currently a director of the Company. From 2002 to 2009, Mr. Weiss was the Chairman and Chief Executive Officer of Keryx Biopharmaceuticals, Inc., where he helped the company acquire and develop its lead drug, Auryxia®, as well as executed a strategic alliance for Auryxia with Japan Tobacco, Inc. and Torii Pharmaceutical Co., Ltd. worth more than $100 million. Mr. Weiss began his professional career as a lawyer with Cravath, Swaine & Moore LLP. He earned his J.D. from Columbia Law School and his B.S. in Finance from The University at Albany. Based on Mr. Weiss's biotechnology and pharmaceutical industry experience, as well as his extensive management experience, the Board of Directors believes that Mr. Weiss has the appropriate set of skills to serve as a member of the Board. Mr. Weiss also serves as a director and Executive Vice Chairman, Strategic Development of Fortress Biotech, Inc., as Chairman of the Board of Directors and Executive Chairman of Mustang Bio, Inc., and as Chairman of the Board of Directors of Checkpoint Therapeutics, Inc. Additionally, Mr. Weiss co-founded and served as Co-Portfolio Manager and Managing Partner of Opus Point Partners, LLC from 2009 to 2019.

Laurence N. Charney, 74, has served on our Board since April 2012. Since 2007, Mr. Charney has served as a business strategist and financial advisor to Boards, CEOs and investors. Previously, from 1970 through June 2007, Mr. Charney was a senior audit partner at Ernst & Young, LLP, a registered public accounting firm, retiring as a practice leader in the Americas Quality and Risk Management Group. Mr. Charney currently serves as a director and audit committee chairman of Kenon Holdings Ltd.

(through November 2018, the date of emergence from Chapter 11), Marvel Entertainment, Inc. (through the sale to The Walt Disney Company in 2009), and Iconix Brand Group, Inc (through August 2013). In addition to his extensive experience on the boards of various corporate entities, Mr. Charney is also very active on the boards of several non¬profit organizations. Mr. Charney graduated with a B.B.A. degree from Hofstra University and completed the Executive MBA in Business program at Columbia University. Based on Mr. Charney's financial industry experience and in-depth understanding of our business, the Board of Directors believes that Mr. Charney has the appropriate set of skills to serve as a member of the Board.

William J. Kennedy, PhD., 76, has served on our Board since April 2012. Dr. Kennedy is a regulatory-affairs professional with over 27 years of domestic and international experience. Prior to his retirement, Dr. Kennedy was Vice President for Regulatory Affairs for Zeneca Corporation.

Before joining the pharmaceutical industry, Dr. Kennedy was an Associate Research Professor at Yale Medical School. Dr. Kennedy is the author of several articles and is ought after as a speaker for his insight into the regulatory process. He co-founded the website PDUFADate.com which provides regulatory opinions to the financial community. Dr. Kennedy was the recipient of the Regulatory Affairs Professional Society's prestigious Special Recognition Award in 1998. Dr. Kennedy has been an independent consultant to the pharmaceutical industry since 1999. Based on Mr. Kennedy's biotechnology and pharmaceutical industry experience, as well as his extensive management experience, the Board of Directors believes that Mr. Kennedy has the appropriate set of skills to serve as a member of the Board.

had a key role in the isolation and characterization of the Hedgehog genes, the first identified vertebrate morphogens. From 1994 to 2010, he progressed through various positions of increasing responsibility at Genzyme Transgenics Corporation and at GTC Biotherapeutics, including Vice President of Research and Development. In 1998, he led the scientific team that first performed goat somatic cell nuclear transfer (cloning). Focusing on Corporate Development, Dr. Echelard spearheaded the creation of a collaborative Joint Venture with LFB Biotechnologies in 2006, which was focused on the development of recombinant plasma proteins and monoclonal antibodies. This close collaboration led to the acquisition of GTC Biotherapeutics, Inc. by LFB in December 2010. In January of 2013, Dr. Echelard became the President and Chief Executive Officer of EVO Biologics, the successor of GTC Biotherapeutics, Inc., a position he held until April 2018. Based on Mr. Echelard's biotechnology and pharmaceutical industry experience, as well as his extensive management experience, the Board of Directors believes that Mr. Echelard has the appropriate set of skills to serve as a member of the Board.

Kenneth Hoberman, 56, has served on our Board since December 2014. Mr. Hoberman is currently the Chief Operating Officer and Corporate Secretary of Stemline Therapeutics, Inc. where he was a key member of the founding team. He was instrumental in the company's financings from early private, including institutional, rounds through the IPO and subsequent follow-on offerings. He has extensive financial, accounting, investor relations, corporate governance and business development experience including M&A, strategic alliances and partnerships both domestic and international. His operational expertise includes regulatory oversight, human resources, manufacturing and clinical development. He was previously Vice President of Corporate and Business Development of Keryx Biopharmaceuticals, Inc., where he was instrumental in the success of the company.

He received a B.S.B.A. in Finance from Boston University and completed post-baccalaureate studies at Columbia University. Based on Mr. Hoberman's financial and pharmaceutical industry experience and in-depth understanding of our business, as well as his extensive management experience, the Board of Directors believes that Mr. Hoberman has the appropriate set of skills to serve as a member of the Board.

Daniel Hume, 54, has served as a member of our Board of Directors since June 2015. Mr. Hume is currently a managing partner at Kirby McInerney, LLP. Mr. Hume's law practice focuses on securities law regulation, structured finance, antitrust, and other complex financial litigation. Until recently, Mr. Hume was a member of the board of directors of Stemline Therapeutics Inc.

Mr. Hume received a B.A. in philosophy and graduated magna cum laude from the State University of New York at Albany, and earned a J.D. from the Columbia University Law School, where he served as Notes Editor for the Columbia Journal of Environmental Law. We believe that Mr. Hume is qualified to serve on our Board of Directors due to his substantial financial and legal experience as well as his experience on several other Boards, some within the pharmaceutical industry.

During 2020, our Board held 10 meetings. Each incumbent director who served their full term and are standing for election attended at least 75% of the meetings of the Board of Directors and the meetings of those committees on which each incumbent director served, in each case during the period that such person was a director. The permanent committees established by our Board of Directors are the Audit Committee, the Compensation Committee and the Nominating Committee, descriptions of which are set forth in more detail below. Our directors are expected to attend each Annual Meeting of Stockholders, and it is our expectation that all of the directors standing for election will attend this year's Annual Meeting. Last year, all of our directors attended the 2020 Annual Meeting of Stockholders (the '2020 Annual Meeting').

Communicating with the Board of Directors

Our Board has established a process by which stockholders can send communications to the Board. You may communicate with the Board as a group, or to specific directors, by writing to Sean A. Power, our Corporate Secretary, at our offices located at 2 Gansevoort Street, 9th Floor, New York, New York 10014. The Corporate Secretary will review all such correspondence and regularly forward to the Board a summary of all correspondence and copies of all correspondence that deals with the functions of the Board or committees thereof or that otherwise requires their attention. Directors may at any time review a log of all correspondence we receive that is addressed to members of our Board and request copies of any such correspondence. Concerns relating to accounting, internal controls, or auditing matters may be communicated in this manner, or may be submitted on an anonymous basis via e-mail at [email protected]. These concerns will be immediately brought to the attention of our Audit Committee and resolved in accordance with procedures established by our Audit Committee.

Audit Committee

The Audit Committee currently consists of Laurence N. Charney (Chairman), William Kennedy and Kenneth Hoberman.

The Audit Committee held six meetings during the fiscal year ended December 31, 2020. The duties and responsibilities of the Audit Committee are set forth in the Charter of the Audit Committee which was recently reviewed by our Audit Committee. Our Audit Committee determined that no revisions needed to be made to the charter at this time. A copy of the Charter of the Audit Committee is available on our website, located at www.tgtherapeutics.com. Among other matters, the duties and responsibilities of the Audit Committee include reviewing and monitoring our financial statements and internal accounting procedures, the selection of our independent registered public accounting firm and consulting with and reviewing the services provided by our independent registered public accounting firm. Our Audit Committee has sole discretion over the retention, compensation, evaluation and oversight of our independent registered public accounting firm.

The SEC and Nasdaq have established rules and regulations regarding the composition of audit committees and the qualifications of audit committee members. Our Board of Directors has examined the composition of our Audit Committee and the qualifications of our Audit Committee members in light of the current rules and regulations governing audit committees. Based upon this examination, our Board of Directors has determined that each member of our Audit Committee is independent and is otherwise qualified to be a member of our Audit Committee in accordance with the rules of the SEC and Nasdaq.

Additionally, the SEC requires that at least one member of the Audit Committee have a 'heightened' level of financial and accounting sophistication. Such a person is known as the 'audit committee financial expert' under the SEC's rules. Our Board has determined that Mr. Charney is an 'audit committee financial expert,' as the SEC defines that term, and is an independent member of our Board of Directors and our Audit Committee. Please see Mr. Charney's biography on page 6 for a description of his relevant experience.

The report of the Audit Committee can be found on page 13 of this proxy statement.

A copy of the Charter of the Compensation Committee is available on our website, located at www.tgtherapeutics.com.

The Compensation Committee may delegate its authority to grant awards to certain employees, and within specified parameters under the Company's Amended and Restated 2012 Incentive Plan, to a special committee consisting of one or more directors who may but need not be officers of the Company.

The Nominating and Corporate Governance Committee (1) identifies qualified individuals to become members of our Board of Directors and recommend to our Board of Directors proposed nominees for Board membership using the criteria set forth in the Company's Director Nomination Policy, available on our website, (2) recommend to our Board of Directors individuals to serve on each committee of our Board of Directors, (3) assess our Board of Directors' effectiveness and develop and implement the Company's corporate governance guidelines, (4) monitor significant developments in the law and practice of corporate governance and of the duties and responsibilities of directors of public companies, and (5) perform such other tasks as our Board of Directors may, from time to time, prescribe.

We identify potential nominees to serve as directors through a variety of business contacts, including current executive officers, directors, community leaders and stockholders. We may, to the extent they deem appropriate, retain a professional search firm and other advisors to identify potential nominees.

We will also consider candidates recommended by stockholders for nomination to our Board. A stockholder who wishes to recommend a candidate for nomination to our Board must submit such recommendation to our Corporate Secretary, Sean A. Power, at our offices located at 2 Gansevoort Street, 9th Floor, New York, New York 10014. Any recommendation must be received not less than 60 calendar days nor more than 90 calendar days before the anniversary date of the previous year's annual meeting. All stockholder recommendations of candidates for nomination for election to our Board must be in writing and must set forth the following: (i) the candidate's name, age, business address, and other

9

Table of Contents

contact information, (ii) the number of shares of common stock beneficially owned by the candidate, (iii) a complete description of the candidate's qualifications, experience, background and affiliations, as would be required to be disclosed in the proxy statement pursuant to Schedule 14A under the Exchange Act, (iv) a sworn or certified statement by the candidate in which he or she consents to being named in the proxy statement as a nominee and to serve as director if elected, and (v) the name and address of the stockholder(s) of record making such a recommendation.

We believe that our Board as a whole should encompass a range of talent, skill, and expertise enabling it to provide sound guidance with respect to our operations and interests. If our Nominating and Corporate Governance Committee determines that a candidate is qualified to serve on our Board, such candidate is interviewed by at least one of the independent directors and our Chief Executive Officer. Other members of the Board also have an opportunity to interview qualified candidates. The independent directors then determine, based on the background information and the information obtained in the interviews, whether to recommend to the Board that the candidate be nominated for approval by the stockholders to fill a directorship. With respect to an incumbent director whom the independent directors are considering as a potential nominee for re-election, the independent directors review and consider the incumbent director's service during his or her term, including the number of meetings attended, level of participation, and overall contribution to the Board. The manner in which the independent directors evaluate a potential nominee will not differ based on whether the candidate is recommended by our directors or stockholders.

We consider the following qualifications, among others, when making a determination as to whether a person should be nominated to our Board: the independence of the director nominee; the nominee's character and integrity; financial literacy; level of education and business experience, including experience relating to biopharmaceutical companies; whether the nominee has sufficient time to devote to our Board; and the nominee's commitment to represent the long-term interests of our stockholders. We review candidates in the context of the current composition of the Board and the evolving needs of our business. We believe that each of the current members of our Board (who are also our director nominees) has the requisite business, biopharmaceutical, financial or managerial experience to serve as a member of the Board, as described above in their biographies under the heading 'Our Board of Directors.' We also believe that each of the current members of our Board has other key attributes that are important to an effective board, including integrity, high ethical standards, sound judgment, analytical skills, and the commitment to devote significant time and energy to service on the Board and its committees.

We do not have a formal policy in place with regard to diversity in considering candidates for our Board, but the Board strives to nominate candidates with a variety of complementary skills so that, as a group, the Board will possess the appropriate talent, skills and expertise to oversee our business.

Code of Business Conduct and Ethics

We have adopted a Code of Business Conduct and Ethics (the 'Code'), which applies to all of our directors and employees, including our principal executive officer and principal financial officer. The Code includes guidelines dealing with the ethical handling of conflicts of interest, compliance with federal and state laws, financial reporting, and our proprietary information. The Code also contains procedures for dealing with and reporting violations of the Code. We have posted our Code of Business Conduct and Ethics on our website, located at www.tgtherapeutics.com.

AND OTHER MATTERS

CohnReznick LLP, the independent registered public accounting firm that audited our financial statements for the years ended December 31, 2020 and 2019 has served as our independent registered public accounting firm since 2002. We expect a representative of CohnReznick LLP to be present at the Annual Meeting. The representative will have an opportunity to make a statement and will be available to answer your questions.

On April 12, 2021, our Audit Committee unanimously voted to dismiss CohnReznick LLP as the Company's independent registered public accounting firm and to engage KPMG LLP as the Company's independent registered public accounting firm for the 2021 fiscal year.

Our Board has asked the stockholders to ratify the selection of KPMG LLP as our independent registered public accounting firm. See 'Proposal Three: Ratification of Appointment of KPMG LLP as Our Independent Registered Public Accounting Firm' on page 36 of this proxy statement. The Board has reviewed the fees described below and concluded that the payment of such fees is compatible with maintaining CohnReznick LLP's independence. All proposed engagements of CohnReznick LLP, whether for audit services, audit-related services, tax services, or permissible non-audit services, were pre-approved by our Audit Committee.

Audit Fees

For the fiscal years ended December 31, 2020 and 2019, CohnReznick LLP billed us an aggregate of approximately $203,000 and $200,000, respectively, in fees for the professional services rendered in connection with the audits of our annual financial statements included in our Annual Reports on Form 10-K for those two fiscal years, the audit of internal control over financial reporting for those two fiscal years, and the review of our financial statements included in our Quarterly Reports on Form 10-Q during those two fiscal years.

Audit-Related Fees

During the fiscal years ended December 31, 2020 and 2019, CohnReznick LLP billed us an aggregate of approximately $92,000 and $65,000, respectively, for audit-related services reasonably related to the performance of the audits and reviews for those two fiscal years, in addition to the fees described above under the heading 'Audit Fees.'

Tax Fees

During the fiscal years ended December 31, 2020 and 2019, we were not billed by CohnReznick LLP for any fees for professional services rendered for tax compliance, tax advice, and tax planning services.

All Other Fees

During the fiscal years ended December 31, 2020 and 2019, we were not billed by CohnReznick LLP for any fees for services, other than those described above, rendered to us and our affiliates for those two fiscal years.

Pre-Approval of Services

Our Audit Committee has established a policy setting forth the procedures under which services provided by our independent registered public accounting firm will be pre-approved by our Audit Committee. The potential services that might be provided by our independent registered public accounting firm fall into two categories:

Table of Contents

Services that our independent registered public accounting firm may not legally provide include such services as bookkeeping, certain human resources services, internal audit outsourcing, and investment or investment banking advice.

All proposed engagements of our independent registered public accounting firm, whether for audit services or permissible non-audit services, are pre-approved by the Audit Committee. We jointly prepare a schedule with our independent registered public accounting firm that outlines services which we reasonably expect we will need from our independent registered public accounting firm, and categorize them according to the classifications described above. Each service identified is reviewed and approved or rejected by the Audit Committee.

REPORT OF THE AUDIT COMMITTEE

In monitoring the preparation of our financial statements, the Audit Committee met with both management and CohnReznick LLP, our independent registered public accounting firm during the year ended December 31, 2020, to review and discuss all financial statements prior to their issuance and to discuss any and all significant accounting issues. Management and our independent registered public accounting firm advised the Audit Committee that each of the financial statements were prepared in accordance with generally accepted accounting principles. The Audit Committee's review included a discussion of the matters required to be discussed pursuant to Public Company Accounting Oversight Board (United States) Auditing Standard 1301 (Communication with Audit Committees). Auditing Standard 1301 requires our independent registered public accounting firm to discuss with the Audit Committee, among other things, the following:

The Audit Committee has discussed the independence of CohnReznick LLP, our independent registered public accounting firm for the year ended December 31, 2020, including the written disclosures made by CohnReznick LLP to the Audit Committee, as required by PCAOB Rule 3526, 'Communication with Audit Committees Concerning Independence.' PCAOB Rule 3526 requires the independent registered public accounting firm to (i) disclose in writing all relationships that, in the independent registered public accounting firm's professional opinion, may reasonably be thought to bear on independence, (ii) confirm their perceived independence, and (iii) engage in a discussion of independence with the Audit Committee.

Finally, the Audit Committee continues to monitor the scope and adequacy of our internal controls and other procedures, including any and all proposals for adequate staffing and for strengthening internal procedures and controls where appropriate and necessary.

On the basis of these reviews and discussions, the Audit Committee recommended to the Board that it approve the inclusion of our audited financial statements in our Annual Report on Form 10‑K for the fiscal year ended December 31, 2020, for filing with the SEC.

COMPENSATION DISCUSSION AND ANALYSIS

In the paragraphs that follow, we give an overview and analysis of our executive compensation program and philosophy for 2020, the material compensation decisions we made under those programs with respect to our named executive officers, and the material factors that we considered in making those decisions. Later in this proxy statement under the heading 'Executive Compensation,' you will find a series of tables containing specific information about the compensation earned by or paid to the following individuals, whom we refer to as our named executive officers, or NEOs:

Executive Summary

During 2020, we made significant progress in executing our strategic priorities and advancing our product candidates. We had a number of major financial and operational accomplishments during the year, including the following:

Consideration of Prior Advisory Stockholder Vote on Executive Compensation

At the 2019 Annual Meeting of Stockholders, approximately 57% of the shares represented and entitled to vote at the annual meeting were voted to approve the compensation of the Company's named executive officers, as discussed and disclosed in the 2020 Proxy Statement. In considering the results of this advisory vote on executive compensation, the Compensation Committee concluded that the compensation paid to our named executive officers and the Company's executive pay practices enjoyed stockholder support.

The Compensation Committee believes that the core design of our executive compensation program is sound, with an emphasis on short and long-term incentive compensation that rewards our executives when they successfully achieve our corporate goals and objectives and, in turn, deliver value for our shareholders. The advisory vote on executive compensation at the Annual Meeting, and at future meetings, will serve as an additional tool to guide the Board of Directors and the Compensation Committee in evaluating the alignment of the Company's executive compensation program with the interests of the Company and its stockholders.

At the 2019 Annual Meeting of Stockholders, our stockholders expressed a preference that advisory votes on executive compensation be held every three years. Consistent with this preference, the Board of Directors determined to implement an advisory vote on executive compensation every three years until the next required vote on the frequency of stockholder votes on the compensation of executive officers, which is scheduled to occur at our annual meeting of stockholders in 2022.

Compensation Philosophy and Objectives

Our compensation programs are designed to motivate our employees to work toward achievement of our corporate mission to create long-term sustained stockholder value by acquiring, developing and commercializing novel treatments for B-cell malignancies and autoimmune diseases. Attaining our key business and strategic goals depends on attracting, retaining and motivating quality employees in an exceptionally competitive environment. Our industry is highly scientific, regulated, scrutinized and dynamic, and as a result, we require employees that are highly educated, dedicated and experienced. The driving philosophy and objectives behind our executive compensation programs are:

The Compensation Committee has historically compensated executive officers with three compensation components: a base salary, an annual cash bonus, and equity-based compensation. The Compensation Committee believes that cash compensation in the form of base salary and an annual bonus provides our executive officers with short-term rewards for success in achieving annual goals and objectives, and that long-term compensation through the award of

16

Table of Contents

restricted stock, stock options, or other equity awards aligns the objectives of management with those of our stockholders with respect to long-term performance and success of the Company.

In setting compensation levels for our executive officers, the Compensation Committee does not formulaically benchmark against any one specific reference point. Instead, it considers a variety of factors, including peer group data, tenure, role, responsibilities, performance, and local competitive market practices. Compensation paid to our named executive officers is delivered primarily through at-risk pay, based on both short-term and long-term incentives, including the achievement of corporate goals and objectives.

Determining Executive Compensation

Role of the Compensation Committee

The Compensation Committee oversees our executive compensation programs, including approving incentive programs, granting equity awards, and determining appropriate levels of compensation for our NEOs. While the Compensation Committee draws on a number of resources, including input from the Board and the Chief Executive Officer to make decisions regarding our executive compensation program, ultimate decision-making authority rests with the Compensation Committee. The Compensation Committee oversees and approves all compensation arrangements and actions for our executive officers. The Compensation Committee relies upon the judgment of its members in making compensation decisions, after reviewing our corporate performance and carefully evaluating an executive's performance during the year against established goals, operational performance, and business responsibilities. In addition, the Compensation Committee utilizes discretion in the assessment process to respond to and adjust to a dynamic business environment. Information about the Compensation Committee and its composition and responsibilities can be found on page 9 under the caption 'Compensation Committee.'

Role of the Executives

Our Chief Executive Officer develops recommendations regarding the compensation levels for our Chief Financial Officer based upon a subjective assessment of his individual performance during the prior year and overall trends in the marketplace. In addition, each year, management delivers a set of proposed corporate goals and objectives that management believes are essential to the achievement of the Company's mission and long-term goals and objectives. The Board of Directors works with the Compensation Committee to review these recommendations and proposals, make any modifications deemed appropriate, and the Compensation Committee approves the final compensation levels and goals and objectives for the NEOs.

Benchmarking and Peer Group

While we do not establish compensation levels based solely on benchmarking, pay practices at other companies are an important factor that the Compensation Committee considers in assessing the reasonableness of compensation and ensuring that our compensation practices are competitive in the marketplace. In order to evaluate the level of compensation for our named executive officers for 2020, we established a peer group of publicly traded companies in the biopharmaceutical and biotechnology industries based on the following criteria:

17

Table of Contents

Our peer group for 2020, referred to as our 2020 peer group, which is used to evaluate compensation actions for the 2020 fiscal year is comprised of the following 20 publicly-traded companies in the pharmaceutical and biotechnology industries:

​

We believe that the compensation practices of our 2020 peer group provided us with appropriate benchmarks for evaluating the compensation of our named executive officers for 2020. At the time that we selected our 2020 peer group we ranked eighth in terms of market capitalization, resulting in the peer group being slightly weighted towards companies with a smaller market capitalization. This analysis was utilized to align the NEO's 2021 base salaries to the peer group, and evaluate how total compensation aligned with our 2020 peer group.

Elements of Compensation

Our executive compensation program for 2020 consisted of the following components:

​

No specific formula is used in regard to the allocation of the various elements within our executive compensation program. The Compensation Committee retains the discretion to reduce or eliminate the payment that otherwise might be payable to our executives based upon unforeseen events occurring during the year or its assessment of the Company's or our executives' performance in general.

In order to maximize the incentive effect of our compensation program, we have structured our performance-based compensation to include a mix of value opportunities and performance measures.

2020 Executive Compensation

Base Compensation

Effective as of January 1, 2017, the Company entered into an amendment (the 'Amendment') to the employment agreement entered as of December 15, 2011 (as amended, the 'Employment Agreement') with Mr. Weiss. Under the Amendment, Mr. Weiss remained as Chief Executive Officer and President of the Company, removing the interim status. Simultaneously, the Company entered into a Strategic Advisory Agreement (the 'Advisory Agreement') with Caribe BioAdvisors, LLC (the 'Advisor') owned by Mr. Weiss to provide services related to Mr. Weiss' service as Chairman of the Board and as Executive Chairman. Pursuant to the Amendment, Mr. Weiss' base salary was reduced from $375,000 to $187,500. Under the Advisory Agreement, the Advisor is paid an annual cash advisory fee which is directly tied to the market capitalization of the Company, starting at $100,000 and escalating up to a maximum annual fee of $1.5 million if the market capitalization of the Company exceeds $3 billion. Effective January 1, 2020 the Compensation Committee approved an increase in Mr. Weiss' base salary from $199,000 to $204,970. No changes or amendments were made to the Advisory Agreement.

Based on the individual performance of Mr. Power, effective January 1, 2020 the Compensation Committee approved an increase in Mr. Power's base salary from $340,000 to $350,200.

Cash Incentive Awards

In 2020, Mr. Weiss was eligible to earn a target annual cash incentive equal to 100% of his base salary, and Mr. Power was eligible to earn a target annual cash incentive equal to 40% of his base salary, per the terms of their respective employment agreements. Both executives' annual cash incentive awards were based upon the Company's performance against pre-established corporate goals and objectives (which at times may exceed 100%), which included a combination of clinical and regulatory goals related to our products as well as other corporate goals, and each executive's individual performance based upon subjective performance reviews.

In December 2020, the Compensation Committee assessed our overall 2020 performance against the achievement of the corporate goals to determine a total percentage of achievement between 0% and 150%. The Compensation

19

Table of Contents

Committee considered the following performance goals, as well as the relative weighting of these goals, in assessing overall performance for the 2020 fiscal year:

​

In assessing performance against these goals, the Compensation Committee reviewed each goal and determined whether or not it was achieved. The Compensation Committee then determined an overall percentage of achievement for all goals combined, which resulted in 113.75% achievement for fiscal year 2020. Accordingly, the executives were paid 113.75% of their target bonus amounts. The actual amounts paid to the executives pursuant to their annual cash incentive awards are reported in the 'Summary Compensation Table' as non-equity incentive plan compensation.

Long-Term Equity Incentive Awards

In connection with the Amendment to Mr. Weiss' employment agreement (as discussed above) Mr. Weiss no longer receives an annual grant of restricted stock. Under the Advisory Agreement, the Advisor receives at each Annual Meeting during the term, a number of restricted shares equal to 1.25% of the shares of Common Stock outstanding on the date of grant on a fully-diluted basis. Each of these annual grants of restricted stock will vest and become non-forfeitable on the date that the 'market capitalization' (as defined in the Advisory Agreement) is $100 million greater than the market capitalization on the respective date of grant, provided that the Advisory Agreement remains in effect and has not been terminated. In accordance with the Advisory Agreement, at the 2020 Annual Meeting, the Advisor was granted an award of 1,556,029 shares of restricted stock. These shares vested when the market capitalization of the Company is $100 million greater than the date of grant, but no earlier than January 1, 2022.

The Compensation Committee had not granted annual equity awards based upon achievement of corporate goals and objectives in 2019 to Mr. Power, primarily due to an insufficient number of shares being available in our 2012 Incentive Plan. Following an amendment to the 2012 incentive plan that was approved at the 2020 Annual Meeting, in

20

Table of Contents

July 2020 Mr. Power was granted an award of 50,000 shares of restricted stock relating to 2019 service and performance. These shares vest according to the following schedule: 50% on January 1, 2022, 25% on January 1, 2023, and 25% on January 1, 2024.

In addition, in July 2020, the Company granted restricted stock to certain employees, including Mr. Power, as a long-term incentive in special recognition for their efforts in several areas, including the Company's clinical trial reports and public securities offerings, and long-standing service to the Company. Mr. Power was granted 200,000 shares of restricted stock which vest according to the following schedule: 50% on January 1, 2022, 25% on January 1, 2023, and 25% on January 1, 2024.

After consideration of our 2020 corporate goals and objectives, and a subjective consideration of Mr. Power's individual performance during 2020, on December 30, 2020 the Compensation Committee granted Mr. Power an award of 20,000 shares of restricted stock. These shares vest in four equal tranches on January 1^st of each year beginning in 2022 and ending in 2025.

For additional information regarding our named executive officers' stock grants, see the 'Summary Compensation Table,' the 'Grants of Plan-Based Awards Table' and the 'Outstanding Equity Awards at 2020 Fiscal Year End' table.

Perquisites and Other Executive Benefits

We do not offer our NEOs any perquisites or other executive benefits.

Severance Benefits

We have employment agreements with our NEOs that provide, among other things, payment and benefits upon certain terminations of employment. We believe the severance benefits components of these agreements is an important component to recruiting and retaining high quality executive officers.

For more information on Mr. Weiss' and Mr. Power's employment agreements see the 'Potential Payments upon Termination or Change-in-Control' section beginning on page 27 of this proxy statement.

Report of the Compensation Committee

The Compensation Committee of the Board of Directors has reviewed and discussed with management the Compensation Discussion and Analysis set forth above. Based on the review and discussions noted above, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement and incorporated by reference in the Company's Annual Report on Form 10‑K for the fiscal year ended December 31, 2020, for filing with the SEC.

CEO PAY RATIO

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, we are providing the following information about the relationship of the median of the annual total compensation of our employees and the annual total compensation of Michael S. Weiss, our CEO. The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. Given the different methodologies that various public companies will use to determine an estimate of their pay ratio, the estimated ratio reported below should not be used as a basis for comparison between companies.

For 2020, our last completed fiscal year, the median of the annual total compensation of all employees of the Company (other than our CEO) was $701,000, and the annual total compensation of our CEO, as reported in the Summary Compensation Table included in this Proxy Statement, was $32,497,239. Based on this information, for 2020, the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all employees was 46 to 1.

We identified our median employee by examining 2020 Box 1 W‑2 taxable income amounts for all individuals, excluding our CEO, who were employed by us on December 31, 2020, whether on a full-time or part-time basis. We annualized the compensation for any permanent (full-time or part-time) employees that were not employed by us for all of 2020. After identifying the median employee, we calculated annual total compensation for such employee using the same methodology we use for our named executive officers as set forth in the 2020 Summary Compensation Table above.

DIRECTOR COMPENSATION

Cash Compensation. Our non-employee directors receive the following cash compensation: (i) $60,000 annual retainer; (ii) $20,000 additional retainer for service as Chairman of the Audit Committee; and (iii) $10,000 additional retainer for service as Chairman of the Compensation Committee. Each non-employee director receives reimbursement for reasonable travel expenses incurred in attending meetings of our Board of Directors and meetings of committees of our Board of Directors.

Equity Compensation. Our non-employee directors receive the following equity compensation under the 2012 Incentive Plan.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The current members of our Compensation Committee are Kenneth Hoberman, Laurence Charney, William Kennedy, Yann Echelard, and Daniel Hume. No member of our Compensation Committee during fiscal year 2020 or as of the date of this proxy statement, is or has been an officer or employee of TG Therapeutics or any of our subsidiaries, nor has any member of our Compensation Committee had any relationship with TG Therapeutics requiring further disclosure.

During the last fiscal year, none of our executive officers served as a director or member of the Compensation Committee (or other committee serving an equivalent function) of any other entity, whose executive officers either served as a member of our Compensation Committee or our Board of Directors.

RELATED-PERSON TRANSACTIONS

In 2012, the Board of Directors of the Company adopted a formal written policy regarding Related Person Transactions (defined below). In order for the Company to ratify a Related Person Transaction under this policy, the Audit Committee must first determine that the transaction is in the best interest of the Company and its stockholders. The policy generally defines a 'Related Person Transaction' as a transaction, arrangement or relationship in which the Company was, is or will be a participant and the amount involved exceeds $120,000, and in which any related person (any executive officer or director of the Company from the previous fiscal year, any person who owns more than 5% of the Company's securities, or any immediate family member in either of these categories) had, has or will have a direct or indirect material interest. In order to further ensure compliance with the policy, any executive officer, director, or nominee for director is required to submit a questionnaire to the Company on an annual basis. Each individual is also required to update the questionnaire following any relevant change.

In connection with our licensing agreement with Ligand Pharmaceuticals Incorporated, which we entered into in June 2014, Opus Point Partners Management, LLC ('Opus'), who identified the opportunity and advised us on the transaction, will be entitled to receive a 1% royalty for annual sales of up to $1 billion. During the years ended December 31, 2020, 2019 and 2018, no royalties were paid to Opus under this agreement.

In October 2014, we entered into the Office Agreement with Fortress Biotech, Inc. ('FBIO'), to occupy approximately 45% of the 24,000 square feet of New York City office space leased by FBIO. The Office Agreement requires us to pay our respective share of the average annual rent and other costs of the 15‑year lease. We approximate an average annual rental obligation of $1.1 million under the Office Agreement. We began to occupy this new space in April 2016, with rental payments beginning in the third quarter of 2016. At January 1, 2019, we recognized a lease liability of $9.3 million, with a corresponding Right of Use (ROU) asset of $7.7 million based on the present value of the remaining lease payments for all of our leased office spaces, the majority of which is comprised of our New York City office space. Mr. Weiss, our Executive Chairman and CEO, is also Executive Vice Chairman of FBIO.

Under the Office Agreement, we agreed to pay FBIO our portion of the build out costs, which have been allocated to us at the 45% rate mentioned above. The allocated build-out costs have been recorded in Leasehold Interest, net on the Company's condensed consolidated balance sheets and will be amortized over the 15‑year term of the Office Agreement. The initial commitment period of the 45% rate was for a period of three (3) years. We and FBIO currently determine actual office space utilization annually and if our utilization differs from the amount we have been billed, we will either receive credits or be assessed incremental utilization charges. As of December 31, 2020, the allocation rate is 65% and will be evaluated again in August 2021 for the following rent year. Also, in connection with this lease, in October 2014 we pledged $0.6 million to secure a line of credit as a security deposit for the Office Agreement, which has been recorded as restricted cash in the accompanying consolidated balance sheets. Additional collateral of $0.6 million was pledged in April 2018 to increase the letter of credit for the office space.

In July 2015, we entered into a Shared Services Agreement (the 'Shared Services Agreement') with FBIO to share the cost of certain services such as facilities use, personnel costs and other overhead and administrative costs. This Shared Services Agreement requires us to pay our respective share of services utilized. In connection with the Shared

30

Table of Contents

Services Agreement, we incurred expenses of approximately $0.8 million, $0.9 million and $1.6 million for shared services for the years ended December 31, 2020, 2019 and 2018, primarily related to shared personnel.

In May 2016, as part of a broader agreement with Jubilant, we entered into a sublicense agreement with Checkpoint, a subsidiary of FBIO, for the development and commercialization of Jubilant's novel BET inhibitor program in the field of hematological malignancies. We paid Checkpoint an up-front licensing fee of $1.0 million in July 2016 and incurred expenses of $0.2 million in March 2017 for the first milestone achievement as part of the JBET Agreement.

In March 2015, we entered into a Global Collaboration Agreement ('Collaboration Agreement') with Checkpoint for the development and commercialization of anti-PD-L1 and anti-GITR antibody research programs in the field of hematological malignancies. The Collaboration Agreement was amended in June 2019 and upon execution of the amendment we incurred an upfront fee of $1.0 million. We incurred expenses of approximately $1.1 million and $4.1 million for the years ended December 31, 2020 and 2019, the majority of which relates to manufacturing expenses of PD-L1.

STOCK OWNERSHIP OF OUR DIRECTORS, EXECUTIVE OFFICERS,

AND 5% BENEFICIAL OWNERS

The following table shows information, as of April 20, 2021, concerning the beneficial ownership of our common stock by:

As of April 20, 2021, there were [_] shares of our common stock outstanding. In order to calculate a stockholder's percentage of beneficial ownership, we include in the calculation those shares underlying options or warrants beneficially owned by that stockholder that are vested or that will vest within 60 days of April 20, 2021. Shares of restricted stock are deemed to be outstanding. Options or warrants held by other stockholders that are not attributed to the named beneficial owner are disregarded in this calculation. Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to the shares of our common stock. Unless we have indicated otherwise, each person named in the table below has sole voting power and investment power for the shares listed opposite such person's name, except to the extent authority is shared by spouses under community property laws.

PROPOSAL TWO

APPROVAL OF THE AMENDMENT OF THE CERTIFICATE OF INCORPORATION

Description of Proposal

The Company's Certificate of Incorporation, as amended (the 'Certificate of Incorporation') currently authorizes the Company to issue up to 150,000,000 shares of Common Stock. On April 20, 2021, the Board of Directors approved, subject to stockholder approval, an amendment of the Company's Certificate of Incorporation to increase the maximum number of shares of the Company's stock authorized to 175,000,000 shares of Common Stock.

The Board of Directors has determined that an increase in the number of shares authorized for issuance, thereby increasing the number of shares of Common Stock authorized for issuance, is in the Company's best interests. The proposed increase in the number of shares of Common Stock authorized for issuance will ensure that shares will be available, if needed, for issuance in connection with grants of equity awards under our equity incentive plans, possible acquisitions, partnering, financings, potential share purchases under existing licensing agreements, and other corporate purposes. The Board of Directors believes that the availability of the additional shares for such purposes, without delay or the necessity for a special stockholders' meeting, would be beneficial to the Company. The Company does not have any immediate plans, arrangements, commitments or understandings with respect to the issuance of any of the additional shares of Common Stock that would be authorized by the proposed amendment. No further action or authorization by the Company's stockholders would be necessary prior to the issuance of the additional shares of Common Stock, unless required by applicable law or regulatory agencies or by the rules of any stock market on which the Company's securities may then be listed. A copy of the proposed Amended and Restated Certificate of Incorporation is attached hereto as Appendix A.

The holders of any of the additional shares of Common Stock issued in the future would have the same rights and privileges as the holders of the Common Stock currently authorized and outstanding. Those rights do not include preemptive rights with respect to the future issuance of any additional shares.

Outstanding Capital Stock and Shares of Capital Stock Available for Issuance

As of April 20, 2021, [] shares of Common Stock were issued and [] shares were outstanding, an aggregate of [] shares of Common Stock were reserved for issuance upon the exercise of outstanding options granted under our existing stock plan, and an aggregate of [] shares of Common Stock were reserved for issuance upon the exercise of future option grants under such plan. No shares of Preferred Stock were issued and outstanding. As a result, as of April 20, 2020, we have [] shares of Common Stock available for issuance. If the proposed amendment is approved, 25,000,000 additional shares of Common Stock would be authorized but unissued, resulting in a total of [] shares of Common Stock available for future issuance.

Potential Anti-Takeover Effect and Other Provisions

The proposal to increase the number of shares of Common Stock that we are authorized to issue could have a potential anti-takeover effect, even though our Board of Directors is not presenting the proposal for that reason and does not presently anticipate using the increased authorized shares for such purpose. The effect of the proposed increase in the authorized number of shares of Common Stock might render more difficult or discourage a merger, tender offer, proxy contest or change in control and the removal of management, which a majority of independent stockholders might otherwise deem favorable. The authority of our Board of Directors to issue Common Stock might be used to create voting impediments or to frustrate an attempt by another person or entity to effect a takeover or otherwise gain control of the Company, because the issuance of additional shares of Common Stock would dilute the voting power of the Common Stock and Preferred Stock then outstanding. The additional shares of Common Stock could also be issued to purchasers who would support our Board of Directors in opposing a takeover bid that our Board of Directors determines not to be in the best interests of the Company or our stockholders. We are not currently aware of any pending or proposed transaction involving a change in control. While authorization of additional shares may be deemed to have potential anti-takeover

34

Table of Contents

effects, this proposal is not prompted by any specific effort or perceived threat of takeover. Our Board of Directors does not currently have any plans to implement additional measures that may have an anti-takeover effect.

Various provisions of our Certificate of Incorporation, our Amended and Restated Bylaws and of Delaware corporate law may discourage, delay or prevent a change in control or takeover attempt of the Company by a third party that is opposed by our Board of Directors, including the following: (a) authorization of 'blank check' preferred stock that could be issued by our Board of Directors to make it more difficult for a third party to acquire, or to discourage a third party from acquiring, a majority of our outstanding voting stock; (b) non-cumulative voting for Directors; (c) control by our Board of Directors of the size of our Board of Directors; and (d) advance notice requirements for proposing matters that can be acted upon by our stockholders at stockholder meetings.

We also are subject to Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years following the date the person became an interested stockholder, unless the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a business combination includes mergers, consolidations, sales or other dispositions of assets having an aggregate value in excess of 10% of the consolidated assets of the corporation and certain transactions that would increase the interested stockholder's proportionate share ownership in the corporation. Generally, an interested stockholder is a person who owns 15% or more of a corporation's voting stock or is an affiliate or associate of the corporation and owned 15% or more of the corporation's voting stock within three years prior to the determination of interested stockholder status. The existence of this provision could prevent a takeover of the Company with respect to transactions not approved in advance by our Board of Directors, including takeover attempts that might result in a premium over the market price of our Common Stock.

Proposed Amendment

Our stockholders are being asked to consider and vote upon a proposed amendment of the Company's Certificate of Incorporation to increase the maximum number of shares of the Company's stock authorized from 150,000,000 shares Common Stock, to 175,000,000 shares of Common Stock. Although the Company has no present intent to issue any additional shares of Common Stock, the Board of Directors believes that the additional shares of Common Stock would provide the Company with added flexibility in connection with its future financing and stock issuance requirements, including with respect to possible future stock splits, if any.

Vote Required and Board Recommendation

If a quorum is present, approval of the amendment of our Certificate of Incorporation requires the affirmative vote of stockholders holding a majority of our Common Stock outstanding and entitled to vote at the Annual Meeting. Abstentions will have the same effect as a vote against the proposal.

As this proposal is deemed a routine matter, broker non-votes will not occur with respect to this proposal.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE 'FOR' THE APPROVAL OF THE AMENDMENT OF OUR CERTIFICATE OF INCORPORATION.

PROPOSAL THREE:

RATIFICATION OF APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT

REGISTERED PUBLIC ACCOUNTING FIRM

The Board is submitting the selection of KPMG LLP as our independent registered public accounting firm to the stockholders for ratification at our Annual Meeting. Stockholder ratification of our independent registered public accounting firm is not required by our Bylaws or otherwise.

On April 12, 2021, the Audit Committee unanimously voted to dismiss CohnReznick LLP as the Company's independent registered public accounting firm and to engage KPMG LLP as the Company's independent registered public accounting firm for the 2021 fiscal year.

CohnReznick LLP's reports on the Company's financial statements for each of the fiscal years ended December 31, 2020 and December 31, 2019 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles. During the Company's fiscal years ended December 31, 2020 and December 31, 2019, and through the date of dismissal, there were no disagreements with CohnReznick on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to the satisfaction of CohnReznick, would have caused CohnReznick to make reference to the subject matter of the disagreement in connection with its report.

During the fiscal years ended December 31, 2020 and December 31, 2019 and the subsequent period through the date of dismissal, there have been no reportable events within the meaning of Item 304(a)(1)(v) of Regulation S-K promulgated by the Securities and Exchange Commission.

During the fiscal years ended December 31, 2020 and December 31, 2019 and the subsequent period to the date of its engagement, neither the Company nor anyone acting on its behalf has consulted with KPMG LLP regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements, and neither a written report or oral advice was provided to the Company that KPMG LLP concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue; (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K; or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.

If KPMG LLP is not ratified as our independent registered public accounting firm by a majority of the shares present or represented by proxy, the Audit Committee will review its future selection of independent registered public accounting firm. KPMG LLP will still serve as our independent registered public accounting firm for the year ending December 31, 2021, if it is not ratified by our stockholders.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE 'FOR' RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2021. THE AFFIRMATIVE VOTE OF THE MAJORITY OF SHARES PRESENT IN PERSON OR REPRESENTED BY PROXY AT THE MEETING AND ENTITLED TO VOTE ON THE SUBJECT MATTER IS REQUIRED FOR THE RATIFICATION OF THE APPOINTMENT OF KPMG LLP.

CERTIFICATE OF INCORPORATION

OF TG THERAPEUTICS, INC.

TG Therapeutics, Inc., a corporation organized and existing under and by virtue of the Delaware General Corporation Law (the 'Corporation'), does hereby certify:

FIRST: That on April 20, 2021, the Board of Directors of the Corporation adopted resolutions setting forth a proposed amendment to the Amended and Restated Certificate of Incorporation of the Corporation and declaring its advisability. The proposed amendment is as follows:

RESOLVED, that the Corporation's Amended and Restated Certificate of Incorporation be amended by deleting Article FOURTH in its entirety and by substituting in lieu thereof the following:

'FOURTH: A. The Corporation is authorized to issue two classes of stock designated 'Common Stock' and 'Preferred Stock,' respectively. The total number of shares of Common Stock authorized to be issued is 175,000,000, and each such share will have a par value of $0.001.
