Galectin Therapeutics Reports Fiscal 2020 Financial Results

and Provides Business Update

NORCROSS, Ga. March 31, 2021 – Galectin Therapeutics Inc. (NASDAQ: GALT), the leading developer of therapeutics that target galectin proteins, today reported financial results and provided a business update for the year ended December 31, 2020. These results are included in the Company’s Annual Report on Form 10-K, which has been filed with the U.S. Securities and Exchange Commission and is available at www.sec.gov.

Joel Lewis, Chief Executive Officer and President of Galectin Therapeutics, said, “I am very encouraged by the progress achieved in fiscal 2020, and remain extremely optimistic for 2021. Given the current challenging environment, I am proud of our success, highlighted by site activations and ongoing enrollment of our innovative NAVIGATE study. This global program continues to be the only active late-stage trial of patients with compensated NASH cirrhosis, where the medical need is greatest and with a clinically meaningful endpoint. Our concurrent hepatic impairment study will also provide important information on belapectin tolerance, safety and exposure in advanced cirrhotic patients.

Over the course of the last year at the Board’s direction we have taken aggressive steps to strengthen our organization, adding Pol Boudes as Chief Medical Officer, as well as Mr. Richard Zordani and Dr. Elissa Schwartz to our Board of Directors. These changes informed my decision to accept the role of Chief Executive Officer, and they afforded me the confidence to receive 80% of my compensation in the

form of Galectin stock. Additionally, I believe this breadth of talent reinvigorated Galectin and placed the Company in a position to monetize our assets. This has served to strengthen my commitment to my compensation strategy, which aligns my interests with all shareholders.

More recently, the peer-reviewed publication of a well-recognized mouse model has shown that the combination of belapectin, a galectin-3 inhibitor, with immunotherapy reprograms the tumor microenvironment. This favors anti-tumor immunity, results in better anti-tumor activity, and most importantly, brings further rationale for our ongoing cancer trial combining belapectin with Keytruda^®, a potent PD-1 inhibitor. Providence Cancer Institute is currently conducting the study and preliminary results suggest improved activity and, potentially, improved tolerance of this regimen.

I am extremely confident in our science, our team, and our progress,” concluded Lewis. The upcoming year will be dedicated to advancing our trial in NASH cirrhosis and supporting investigations of belapectin’s safety and efficacy in other indications, such as the ongoing cancer trial in conjunction with the Providence Cancer Institute. I also want to recognize the outstanding efforts of our entire team, who persevered through the challenges precipitated by COVID-19 in the interest of developing a therapy for NASH cirrhosis, a critical, unmet medical need. Let me once again thank the investigators and patients participating in our NAVIGATE trial, where a positive outcome would be very clinically relevant for patients with NASH cirrhosis.”

Richard E. Uihlein, Chairman of the Board, added, “I want to echo Joel’s sentiment and thank Pol, Jack and our entire team for their dedication throughout

this past year, especially their commitment to initiating our exciting NAVIGATE trial under less than optimal circumstances due to the global pandemic. Joel has proven to be the leader we all expected, and I am pleased with the progress he has achieved since assuming the role and confident in his ability to unlock the value of our proprietary compound, belapectin. Peer-reviewed research, such as that recently published in OncoImmunology, clearly confirms our basic scientific premise regarding belapectin’s anti-inflammatory characteristics in a broad range of fibrosis as well as its ability to potentially enhance the efficacy of cancer therapies. As such, the NAVIGATE trial represents an opportunity to further demonstrate the anti-inflammatory activity of belapectin, which would open up vast new opportunities to investigate other indications and establish our compound as a foundation for a platform technology.”

NAVIGATE Trial Update

• The NAVIGATE trial uses a seamless, adaptive design to confirm dose selection and reaffirm the observed efficacy of belapectin to prevent the development of esophageal varices in the NASH-CX trial. Pre-planned adaptations will inform the larger Phase 3 trial component.

• Key clinical study milestones:

• First patient randomized August 2020

• 130+ sites, 12 countries in North America, Europe, Asia and Australia

• Phase 2b part to Interim Analysis will be ~315 patients

• Recruiting period for phase 2b portion now expected to conclude around the end of 2021 due to COVID-19 impact on recruitment

• Key inclusion criteria - NASH cirrhosis (baseline or historical liver biopsy), clinical sign of portal hypertension, no esophageal varices (esophago-gastro endoscopy)

• Interim analysis expected late 2023

Peer-reviewed publication, Scientific Presentations and Conferences

• OncoImmunology published a peer-reviewed article describing how belapectin, a potent galectin-3 inhibitor, in combination with an anti-OX40 (CD134) monoclonal antibody, reduces tumor progression compared to either agent alone. The paper, titled “Galectin-3 inhibition with belapectin combined with anti-OX40 therapy reprograms the tumor microenvironment to favor anti-tumor immunity,” describes results from a collaboration between Galectin Therapeutics and Providence Cancer Institute highlighting the mechanism of action of the combination which is explained by a reduction in myeloid-derived suppressor cell infiltration and function coupled to an increase in T-cell effector function. For many years, galectin-3 has been known to play a key role in the control of tumor-induced immunosuppression. Galectin-3 acts to maintain tumor growth, in part, by supporting the generation of suppressive macrophages and inhibiting T cell function. This creates an attractive rationale for the use of a galectin-3 inhibitor, such as belapectin, to improve anti-tumor activities of multiple cancer therapies.

Financial Results

For the year ended December 31, 2020, the Company reported a net loss applicable to common stockholders of $23.6 million, or ($0.41) per share, compared to a net loss applicable to common stockholders of $20.2 million, or ($0.39) per share for the full year 2019. The increase is largely due to an increase in research and development expenses related to our NAVIGATE clinical trial, partially offset by a non-cash, one-time warrant modification charge of $6.6 million in 2019.

Page 4 of 8

Research and development expense for 2020 was $18.0 million compared with $7.5 million for 2019. The increase was primarily due to costs related to our NAVIGATE clinical trial, along with preparations and some preclinical activities incurred in support of the clinical program, such as development and reproductive toxicity studies, clinical supplies and other supportive activities. General and administrative expenses for 2020 were $5.5 million, down from $6.0 million for the full year 2019, primarily due to decreases in legal, investor relations and non-cash stock-based compensation expenses partially offset by an increase in insurance expenses.

As of December 31, 2020, the Company had $27.1 million of cash and cash equivalents. The Company also has a $10 million unsecured line of credit, under which no borrowings have been made to date. The Company believes it has sufficient cash, including availability under the line of credit, to fund currently planned operations and research and development activities through at least March 31, 2022.

The Company expects that it will require more cash to fund operations after March 31, 2022, and believes it will be able to obtain additional financing as needed. The currently planned operations include costs related to our adaptively designed NAVIGATE Phase 2b/3 clinical trial. Currently, we expect to require an additional approximately $45-$50 million to cover costs of the trial to reach the planned interim analysis estimated to occur in the second half of 2023 along with drug manufacturing and other scientific support activities and general and administrative costs and further amounts to complete the Phase 3 portion of the trial. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be on terms favorable to us.
