**TG Therapeutics Provides Business Update and Reports Fourth Quarter and Year-End 2022 Financial Results**

*Conference call to be held today, Tuesday, February 28, 2023, at 8:30 AM ET*

New York, NY, (**February 28, 2023)** – TG Therapeutics, Inc. (NASDAQ: TGTX) today announced its financial results for the fourth quarter and year ended December 31, 2022, and recent company developments.

Michael S. Weiss, the Company's Chairman and Chief Executive Officer, stated, "2022 was a pivotal year for TG with the approval of BRIUMVI for relapsing forms of Multiple Sclerosis, and 2023 is off to an exciting start with the commercial launch of BRIUMVI. Our teams are hard at work introducing BRIUMVI to the MS community and while we are only 4 weeks into the launch, we are encouraged by the early feedback from providers, payors and advocates." Mr. Weiss continued, "Our highest priority is our commitment to patients and to ensure that patients who want BRIUMVI will have access to BRIUMVI. We look forward to building on the foundation we are developing in this early launch phase and extending it throughout 2023 and beyond."

**2022 Highlights & Recent Developments** 

&nbsp;&nbsp;&nbsp;&nbsp;● U.S. Food and Drug Administration (FDA) approved BRIUMVI™ (ublituximab-xiiy), for the treatment of relapsing forms of multiple sclerosis (RMS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.

&nbsp;&nbsp;&nbsp;&nbsp;· Commercially launched BRIUMVI making it available for patients and physicians.

&nbsp;&nbsp;&nbsp;&nbsp;· Presented additional data, including new analyses, from the ULTIMATE I and II Phase 3 trials at the 2022 Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) and at the 2023 Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) annual forum.

**Key Objectives for 2023**

&nbsp;&nbsp;&nbsp;&nbsp;· Execute a strong commercial launch of BRIUMVI in RMS

&nbsp;&nbsp;&nbsp;&nbsp;· Obtain broad payor coverage for BRIUMVI

&nbsp;&nbsp;&nbsp;&nbsp;· Continue to present additional data from the ULTIMATE I & II Phase 3 trials of BRIUMVI in RMS

**Financial Results for the Fourth Quarter and Full Year 2022**

&nbsp;&nbsp;&nbsp;&nbsp;· **Product Revenue, net:** Product revenue, net was approximately zero and $2.6 million for the three and twelve months ended December 31, 2022. Net product revenues during the year represent U.S. sales of UKONIQ, which received approval in February of 2021 and was withdrawn from the U.S. market effective May 31, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;· **R&D Expenses:** Total research and development (R&D) expense was $29.6 million and $125.4 million for the three and twelve months ended December 31, 2022, compared to $62.6 million and $222.6 million for the three and twelve months ended December 31, 2021. The decrease in R&D expense is primarily attributable to reduced clinical trial related expenses, license milestones and manufacturing expense, decreased headcount and lower fees paid to consultants and outside service providers, as well as a decrease in non-cash compensation R&D expense during the twelve months ended December 31, 2022 over the comparable period in 2021.

&nbsp;&nbsp;&nbsp;&nbsp;· **SG&A Expenses:** Total selling, general and administrative (SG&A) expense was $22.5 million and $70.0 million for the three and twelve months ended December 31, 2022, and $32.4 million and $128.1 million for the three and twelve months ended December 31, 2021. The decrease was primarily attributable to reduced other selling, general and administrative costs as a result of our withdrawal of UKONIQ and decreased headcount during the period ended December 31, 2022, as well as decreased non-cash compensation G&A expense during the twelve months ended December 31, 2022 over the comparable period in 2021.

&nbsp;&nbsp;&nbsp;&nbsp;· **Net Loss:** Net loss was $53.0 million and $198.3 million for the three and twelve months ended December 31, 2022, compared to $93.3 million and $348.1 million for the three and twelve months ended December 31, 2021. Excluding non-cash compensation, the net loss for the three and twelve months ended December 31, 2022 was approximately $41.9 million and $179.2 million, compared to a net loss of $79.0 million and $286.8 million for the three and twelve months ended December 31, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;● **Cash Position and Financial Guidance:** Cash, cash equivalents and investment securities were $174.1 million as of December 31, 2022. We anticipate that our cash, cash equivalents and investment securities as of December 31, 2022, combined with the $45.0 million of available capacity under our existing term loan facility and projected revenues, will be sufficient to fund the Company ' s planned operations into mid-2024.

**ABOUT BRIUMVI™ (ublituximab-xiiy) 150 mg/6 mL Injection for IV**

BRIUMVI is a novel monoclonal antibody that targets a unique epitope on CD20-expressing B-cells. Targeting CD20 using monoclonal antibodies has proven to be an important therapeutic approach for the management of autoimmune disorders, such as RMS. BRIUMVI is uniquely designed to lack certain sugar molecules normally expressed on the antibody. Removal of these sugar molecules, a process called glycoengineering, allows for efficient B-cell depletion at low doses.

BRIUMVI is indicated for the treatment of adults with relapsing forms of multiple sclerosis (RMS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.

A list of authorized specialty distributors can be found at www.briumvi.com.

**IMPORTANT SAFETY INFORMATION**

**Contraindications: BRIUMVI is contraindicated in patients with:**

&nbsp;&nbsp;&nbsp;&nbsp;· Active HBV infection

&nbsp;&nbsp;&nbsp;&nbsp;· A history of life-threatening infusion reaction to BRIUMVI

**WARNINGS AND PRECAUTIONS**

**Infusion Reactions:** BRIUMVI can cause infusion reactions, which can include pyrexia, chills, headache, influenza-like illness, tachycardia, nausea, throat irritation, erythema, and an anaphylactic reaction. In MS clinical trials, the incidence of infusion reactions in BRIUMVI-treated patients who received infusion reaction-limiting premedication prior to each infusion was 48%, with the highest incidence within 24 hours of the first infusion. 0.6% of BRIUMVI-treated patients experienced infusion reactions that were serious, some requiring hospitalization.

Observe treated patients for infusion reactions during the infusion and for at least one hour after the completion of the first two infusions unless infusion reaction and/or hypersensitivity has been observed in association with the current or any prior infusion. Inform patients that infusion reactions can occur up to 24 hours after the infusion. Administer the recommended pre-medication to reduce the frequency and severity of infusion reactions. If life-threatening, stop the infusion immediately, permanently discontinue BRIUMVI, and administer appropriate supportive treatment. Less severe infusion reactions may involve temporarily stopping the infusion, reducing the infusion rate, and/or administering symptomatic treatment.

**Infections:** Serious, life-threatening or fatal, bacterial and viral infections have been reported in BRIUMVI-treated patients. In MS clinical trials, the overall rate of infections in BRIUMVI-treated patients was 56% compared to 54% in teriflunomide-treated patients. The rate of serious infections was 5% compared to 3% respectively. There were 3 infection-related deaths in BRIUMVI-treated patients. The most common infections in BRIUMVI-treated patients included upper respiratory tract infection (45%) and urinary tract infection (10%). Delay BRIUMVI administration in patients with an active infection until the infection is resolved.

Consider the potential for increased immunosuppressive effects when initiating BRIUMVI after immunosuppressive therapy or initiating an immunosuppressive therapy after BRIUMVI.

***Hepatitis B Virus (HBV) Reactivation:*** HBV reactivation occurred in an MS patient treated with BRIUMVI in clinical trials. Fulminant hepatitis, hepatic failure, and death caused by HBV reactivation have occurred in patients treated with anti-CD20 antibodies. Perform HBV screening in all patients before initiation of treatment with BRIUMVI. Do not start treatment with BRIUMVI in patients with active HBV confirmed by positive results for HBsAg and anti-HB tests. For patients who are negative for surface antigen [HBsAg] and positive for HB core antibody [HBcAb+] or are carriers of HBV [HBsAg+], consult a liver disease expert before starting and during treatment.

***Progressive Multifocal Leukoencephalopathy (PML):*** Although no cases of PML have occurred in BRIUMVI-treated MS patients, JCV infection resulting in PML has been observed in patients treated with other anti-CD20 antibodies and other MS therapies.

------

If PML is suspected, withhold BRIUMVI and perform an appropriate diagnostic evaluation. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes.

MRI findings may be apparent before clinical signs or symptoms; monitoring for signs consistent with PML may be useful. Further investigate suspicious findings to allow for an early diagnosis of PML, if present. Following discontinuation of another MS medication associated with PML, lower PML-related mortality and morbidity have been reported in patients who were initially asymptomatic at diagnosis compared to patients who had characteristic clinical signs and symptoms at diagnosis.

If PML is confirmed, treatment with BRIUMVI should be discontinued.

***Vaccinations:*** Administer all immunizations according to immunization guidelines: for live or live-attenuated vaccines at least 4 weeks and, whenever possible at least 2 weeks prior to initiation of BRIUMVI for non-live vaccines. BRIUMVI may interfere with the effectiveness of non-live vaccines. The safety of immunization with live or live-attenuated vaccines during or following administration of BRIUMVI has not been studied. Vaccination with live virus vaccines is not recommended during treatment and until B-cell repletion.

***Vaccination of Infants Born to Mothers Treated with BRIUMVI During Pregnancy:*** In infants of mothers exposed to BRIUMVI during pregnancy, assess B-cell counts prior to administration of live or live-attenuated vaccines as measured by CD19<sup>+</sup> B-cells. Depletion of B-cells in these infants may increase the risks from live or live-attenuated vaccines. Inactivated or non-live vaccines may be administered prior to B-cell recovery. Assessment of vaccine immune responses, including consultation with a qualified specialist, should be considered to determine whether a protective immune response was mounted.

**Fetal Risk:** Based on data from animal studies, BRIUMVI may cause fetal harm when administered to a pregnant woman. Transient peripheral B-cell depletion and lymphocytopenia have been reported in infants born to mothers exposed to other anti-CD20 B-cell depleting antibodies during pregnancy. A pregnancy test is recommended in females of reproductive potential prior to each infusion. Advise females of reproductive potential to use effective contraception during BRIUMVI treatment and for 6 months after the last dose.

**Reduction in Immunoglobulins:** As expected with any B-cell depleting therapy, decreased immunoglobulin levels were observed. Decrease in immunoglobulin M (IgM) was reported in 0.6% of BRIUMVI-treated patients compared to none of the patients treated with teriflunomide in RMS clinical trials. Monitor the levels of quantitative serum immunoglobulins during treatment, especially in patients with opportunistic or recurrent infections, and after discontinuation of therapy until B-cell repletion. Consider discontinuing BRIUMVI therapy if a patient with low immunoglobulins develops a serious opportunistic infection or recurrent infections, or if prolonged hypogammaglobulinemia requires treatment with intravenous immunoglobulins.

**Most Common Adverse Reactions:** The most common adverse reactions in RMS trials (incidence of at least 10%) were infusion reactions and upper respiratory tract infections.

**ABOUT BRIUMVI PATIENT SUPPORT** 

BRIUMVI Patient Support is a flexible program designed by TG Therapeutics to support patients through their treatment journey in a way that works best for them. More information about the BRIUMVI Patient Support program can be accessed at www.briumvipatientsupport.com.

**ABOUT MULTIPLE SCLEROSIS** 

Relapsing multiple sclerosis (RMS) is a chronic demyelinating disease of the central nervous system (CNS) and includes people with relapsing-remitting multiple sclerosis (RRMS) and people with secondary progressive multiple sclerosis (SPMS) who continue to experience relapses. RRMS is the most common form of multiple sclerosis (MS) and is characterized by episodes of new or worsening signs or symptoms (relapses) followed by periods of recovery. It is estimated that nearly 1 million people are living with MS in the United States and approximately 85% are initially diagnosed with RRMS.<sup>1,2</sup> The majority of people who are diagnosed with RRMS will eventually transition to SPMS, in which they experience steadily worsening disability over time. Worldwide, more than 2.3 million people have a diagnosis of MS.<sup>1</sup>
