TG Therapeutics Provides Business Update and Reports Third Quarter 2021 Financial Results

Conference call to be held today, Thursday, November 4, 2021 at 8:30 AM ET

New York, NY, (November 4, 2021) – TG Therapeutics, Inc. (NASDAQ: TGTX) today announced its financial results for the third quarter ended September 30, 2021 and recent company developments, along with a business outlook for the remainder of 2021.

Michael S. Weiss, the Company's Chairman and Chief Executive Officer, stated, “The third quarter of 2021 was an exciting time for us, as we achieved another major milestone by submitting a Biologics License Application (BLA) with the U.S. FDA for ublituximab to treat patients with relapsing forms of multiple sclerosis (RMS). With an estimated 1 million Americans currently living with multiple sclerosis, we believe if approved, ublituximab will provide an attractive new treatment option for patients battling RMS, which is the most common disease course.”

Mr. Weiss continued, “For the remainder of 2021 and into 2022, we look forward to continuing to execute on the UKONIQ launch in patients with relapsed or refractory marginal zone and follicular lymphoma, and also continuing to prepare for the potential launches of ublituximab in combination with UKONIQ or U2 in CLL and ublituximab in RMS.”

2021 Highlights & Recent Developments

Ublituximab in Multiple Sclerosis

● Submitted a Biologics License Application (BLA) to the U.S. FDA for ublituximab to treat patients with relapsing forms of multiple sclerosis (RMS).

● Presented positive results, including new analyses, from the ULTIMATE I and II Phase 3 trials at the 37^th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS). As previously reported, both trials met their primary endpoint with ublituximab treatment demonstrating a statistically significant reduction in annualized relapse rate (ARR) over a 96-week period compared to teriflunomide in patients with RMS. Additional secondary, tertiary and post-hoc sensitivity analyses were also presented, including T1 and T2 lesions, no evidence of disease activity (NEDA), brain volume and multiple sclerosis functional composite (MSFC) score.

Ublituximab plus UKONIQ® (U2) in Chronic Lymphocytic Leukemia

● Received FDA acceptance of a BLA for ublituximab and a supplemental New Drug Application (sNDA) for UKONIQ, both submissions requesting approval of U2 as a treatment for patients with chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). These applications were based on results from the UNITY-CLL Phase 3 trial, which included both treatment-naïve and relapsed or refractory (R/R) CLL patients. The FDA has set a Prescription Drug User Fee Act (PDUFA) goal date of March 25, 2022 for both applications.

● Completed enrollment in the Phase 2 portion of the ULTRA-V trial and launched the Phase 3 portion of the ULTRA-V trial, a randomized trial evaluating the triple combination of U2 plus venetoclax in patients with treatment-naïve and R/R CLL.

● Presented updated results from the Phase 1 trials of U2 plus venetoclax evaluating patients with R/R CLL at the 2021 International Workshop on Chronic Lymphocytic Leukemia (iwCLL).

UKONIQ (umbralisib) in Relapsed or Refractory Marginal Zone Lymphoma & Follicular Lymphoma

● Launched UKONIQ in the U.S. for the treatment of adult patients with relapsed or refractory marginal zone lymphoma (MZL) who have received at least one prior anti-CD20 based regimen and adult patients with relapsed or refractory follicular lymphoma (FL) who have received at least three prior lines of systemic therapy.

● Generated $4.3M in total net UKONIQ revenue from launch through the end of Q3 2021, approximately seven months.

● Achieved broad U.S. payor coverage for more than 95% of Medicare and commercial lives and inclusion in the National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines for MZL and FL.

● Published results from an integrated safety analysis of UKONIQ in Blood Advances.

TG-1701 in B-cell Malignancies

● Presented updated data from TG-1701, our bruton tyrosine kinase (BTK) inhibitor, as a monotherapy and in combination with U2 in patients with B-cell malignancies at the 2021 iwCLL meeting.

Remaining Key Objectives for 2021 and Early 2022

● Continue the commercialization of UKONIQ in R/R MZL and FL and expand commercialization capabilities in preparation for a potential launch of U2 in CLL and ublituximab in RMS.

● Seek to obtain U.S. FDA approval of U2 in CLL and SLL by the PDUFA goal date of March 25, 2022.

● Continue to enroll patients into the newly launched ULTRA-V Phase 3 trial evaluating the triple combination of U2 plus venetoclax.

● Continue to advance our early pipeline candidates including TG-1501 (cosibelimab) our PDL1 inhibitor, TG-1701 our BTK inhibitor and TG-1801 our CD47/CD19 bispecific antibody.

Financial Results for the Three and Nine Months Ended September 30, 2021

● Product Revenue, net: Product revenue, net was approximately $2.0 million and $4.3 million for the three and nine months ended September 30, 2021. Net product revenues represent U.S. sales from our sole commercial product, UKONIQ, which received accelerated approval from the FDA on February 5, 2021.

● R&D Expenses: Total research and development (R&D) expense was $52.0 million and $159.9 million for the three and nine months ended September 30, 2021, compared to $50.5 million and $122.9 million for the three and nine months ended September 30, 2020. The increase was due primarily to costs associated with the submission of our BLA for ublituximab in RMS, manufacturing costs, as well as an increase in non-cash compensation R&D expense during the nine months ended September 30, 2021 over the comparable period in 2020.

● SG&A Expenses: Total selling, general and administrative (SG&A) expense was $34.9 million and $95.7 million for the three and nine months ended September 30, 2021, and $35.3 million and $64.0 million for the three and nine months ended September 30, 2020. The increase during the nine months ended September 30, 2021 was due to selling, general and administrative costs associated with execution of the launch of UKONIQ and planning for the potential launches of U2 in CLL and ublituximab in RMS. We expect our selling, general and administrative expenses to increase for the remainder of 2021 as we continue to prepare for those potential 2022 launches.

● Net Loss: Net loss was $85.6 million and $254.8 million for the three and nine months ended September 30, 2021, compared to $87.2 million and $191.2 million for the three and nine months ended September 30, 2020. Excluding non-cash compensation, the net loss for the three and nine months ended September 30, 2021 was approximately $71.6 million and $207.8 million, compared to a net loss of $58.8 million and $144.4 million for the three and nine months ended September 30, 2020.

● Cash Position and Financial Guidance: Cash, cash equivalents and investment securities were $381.4 million as of September 30, 2021, which the Company believes will be sufficient to fund the Company's planned operations into 2023.
