GALECTIN THERAPEUTICS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation

Galectin Therapeutics Inc. and subsidiaries (the “Company”) is a clinical stage biopharmaceutical company that is applying its leadership in galectin science and drug development to create new therapies for fibrotic disease and cancer. These candidates are based on the Company’s targeting of galectin proteins which are key mediators of biologic and pathologic function. These compounds also may have application for drugs to treat other diseases and chronic health conditions.

The unaudited condensed consolidated financial statements as reported in this Quarterly Report on Form 10-Q reflect all adjustments which are, in the opinion of management, necessary to present fairly the financial position of the Company as of March 31, 2021 and the results of its operations for the three months ended March 31, 2021 and 2020 and its cash flows for the three months ended March 31, 2021 and 2020. All adjustments made to the interim financial statements include all those of a normal and recurring nature. Amounts presented in the condensed consolidated balance sheet as of December 31, 2020 are derived from the Company’s audited consolidated financial statements as of that date, but do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date these financial statements are available to be issued. The results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. The unaudited condensed consolidated financial statements of the Company should be read in conjunction with its Annual Report on Form 10-K for the year ended December 31, 2020.

The Company has operated at a loss since its inception and has had no revenues. The Company anticipates that losses will continue for the foreseeable future. At March 31, 2021, the Company had $20,760,000 of unrestricted cash and cash equivalents available to fund future operations. On April 16, 2021, the Company received $10,000,000 in proceeds from a convertible promissory note (see Note 12). The Company believes there is sufficient cash, including availability of the line of credit (see Note 3), to fund currently planned operations at least through September 30, 2022. We will require more cash to fund our operations after September 30, 2022 and believe we will be able to obtain additional financing. 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 $35-$40 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. 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. If we are unsuccessful in raising additional capital to fund operations before September 30, 2022, we may be required to cease operations. Accordingly, based on the forecasts and estimates underlying our current operating plan, the financial statements do not currently include any adjustments that might be necessary if we are unable to continue as a going concern.

The Company was founded in July 2000, was incorporated in the State of Nevada in January 2001 under the name “Pro-Pharmaceuticals, Inc.,” and changed its name to “Galectin Therapeutics Inc.” on May 26, 2011.

2. Accrued Expenses and Other

Accrued expenses consist of the following:

	March 31, 2021		December 31, 2020
	(in thousands)
Legal and accounting fees	$	122	$	122
Accrued compensation		291		789
Lease liability		42		44
Accrued research and development costs and other		3,826		3,087
Total	$	4,281	$	4,042

Research and development expenses, including personnel costs, allocated facility costs, lab supplies, outside services, contract laboratory costs related to manufacturing drug product, clinical trials and preclinical studies are charged to research and development expense as incurred. The Company accounts for nonrefundable advance payments for goods and services that will be used in future research and development activities as expense when the service has been performed or when the goods have been received. Our current NAVIGATE clinical trial is being supported by third-party contract research organizations, or CROs, and other vendors. We accrue expenses for clinical trial activities performed by CROs based upon the estimated amount of work completed on each trial. For

7

clinical trial expenses and related expenses associated with the conduct of clinical trials, the significant factors used in estimating accruals include the number of patients enrolled, the number of active clinical sites, and the duration for which the patients have been enrolled in the trial. We monitor patient enrollment levels and related activities to the extent possible through internal reviews, review of contractual terms and correspondence with CROs. We base our estimates on the best information available at the time. We monitor patient enrollment levels and related activities to the extent possible through discussions with CRO personnel and based our estimates of clinical trial costs on the best information available at the time. However, additional information may become available to us which will allow us to make a more accurate estimate in future periods. In that event, we may be required to record adjustments to research and development expenses in future periods when the actual level of activity becomes more certain.

3. Line of Credit

The Company has a $10 million Line of Credit arrangement with Richard E. Uihlein, a director and shareholder pursuant to an agreement established in December, 2017 and amended in December, 2018 and January, 2019. Under the arrangement the Company may borrow up to $10 million from Mr. Uihlein on an unsecured basis and with any borrowings bearing interest at the Applicable Federal Rate for short terms loans published by the Internal Revenue Service (0.14% in January 2021). Borrowings may be made through December 31, 2021 with repayment due on December 31, 2022. In connection with the Line of Credit agreement, the Company issued to Mr. Uihlein warrants to purchase 1 million shares of the Company’s common stock for $5 per share. Half of the warrants vested at closing of the Line of Credit and the other half vest ratably with borrowings under the agreement. The 500,000 warrants that vested at closing were exercised in May 2019 for cash proceeds to the Company of $2.5 million. As of the date of this Quarterly Report, there have been no borrowings under the Line of Credit.

The fair value of the 500,000 warrants vested at closing in December 2017 was $696,000 at the date of issuance based on the following assumptions: an expected life of 7 years, volatility of 98%, risk free interest rate of 2.05% and zero dividends. The fair value of the vested warrants was recorded in other current assets and other assets (non-current) as a deferred financing cost and were to be amortized on a straight-line basis from December 19, 2017 through December 31, 2019. The remaining unamortized balance of the deferred financing cost on January 11, 2019 was adjusted to be recorded as expense on a straight-line basis through December 31, 2022. Amortization for the three months ended March 31, 2021 and 2020 of $22,000 and $22,000, respectively, was recorded as interest expense. The fair value of warrants that vest in the future based on borrowings will be computed when those borrowings occur and amortized over the remaining period through December 31, 2022 reflecting the second extension.

4. Stock-Based Compensation

Following is the stock-based compensation expense related to common stock options, restricted common stock, common stock warrants and deferred stock units:

	Three Months Ended March 31,
	2021		2020
Research and development	$	67	$	157
General and administrative		187		273
Total stock-based compensation expense	$	254	$	430

The following table summarizes the stock option activity in the Company’s equity incentive plans, including non-plan grants to Company executives, from December 31, 2020 through March 31, 2021:

	Shares			Weighted Average Exercise Price
Outstanding, December 31, 2020		3,987,575		$	4.29
Granted		1,865,000			2.11
Exercised		(70,000	)		0.87
Options forfeited/cancelled		(20,000	)		2.86
Outstanding, March 31, 2021		5,762,575		$	3.63

As of March 31, 2021, there was $3,781,000 of unrecognized compensation related to 2,415,834 unvested options, which is expected to be recognized over a weighted–average period of approximately 2.3 years. The weighted-average grant date fair value for options granted during the three months ended March 31, 2021 was $1.56. The Company granted 1,865,000 stock options during the three months ended March 31, 2021. During the three months ended March 31, 2021, 70,000 stock options were exercised on a net basis resulting in the issuance of 46,282 shares of common stock.

8

The fair value of all other options granted is determined using the Black-Scholes option-pricing model. The following weighted average assumptions were used:

	Three Months Ended March 31,			Three Months Ended March 31,
	2021			2020
Risk-free interest rate		0.54	%		1.55	%
Expected life of the options		6 years			6 years
Expected volatility of the underlying stock		91	%		100	%
Expected dividend rate		0	%		0	%

In January 2020, two directors elected to take restricted stock grants in lieu of cash retainers for 2020. A total of 32,693 shares of restricted stock valued at approximately $93,500 is being amortized to expense on a straight-line basis until January 9, 2021 when the stock vests in full.

In March 2021, one director elected to take a restricted stock grant in lieu of cash retainers for 2021. A total of 16,588 shares of restricted stock valued at approximately $35,000 is being amortized to expense on a straight-line basis until December 31, 2021 when the stock vests in full.

In September 2020, the Company entered into an employment agreement with its new Chief Executive Officer whereby 20% of his base salary and performance bonuses will be paid in cash, and 80% will be paid in the form of deferred stock units (“DSUs”) in accordance with the terms and subject to the provisions set forth in the DSU Agreement. DSUs credited to Mr. Lewis as of any date shall be fully vested and nonforfeitable at all times. The Company shall issue the shares underlying the outstanding whole number of DSUs credited to Mr. Lewis as follows: twenty five percent shall be issued on March 1, 2023, twenty five percent shall be issued on September 1, 2023 and fifty percent shall be issued on March 1, 2024. For the three months ended March 31, 2021, approximately $100,000 of his compensation was recorded as stock compensation expense representing 44,593 shares of common stock to be issued under the DSU agreement with a weighted average grant date fair value of $2.24 per share. Also, Mr. Lewis’ bonus for the year ended December 31, 2020 of $60,000 (which was included in accrued compensation at December 31, 2020) was approved in March 2021 and represents 27,027 shares of common stock to be issued under the DSU agreement with a grant date fair value of $2.22 per share. The $60,000 was reclassified from accrued compensation to additional paid in capital in March 2021. There is no unrecognized compensation expense related to the DSUs. 

5. Common Stock Warrants

The following table summarizes the common stock warrant activity from December 31, 2020 through March 31, 2021:

	Shares		Weighted Average Exercise Price
Outstanding, December 31, 2020		12,538,204	$	4.22
Granted		—		—
Exercised		—		—
Forfeited/cancelled		—		—
Outstanding, March 31, 2021		12,538,204	$	4.22

The weighted average expiration of the warrants outstanding as of March 31, 2021 is 3.2 years.

6. Fair Value of Financial Instruments

The Company has certain financial assets and liabilities recorded at fair value. Fair values determined by Level 1 inputs utilize observable data such as quoted prices in active markets. Fair values determined by Level 2 inputs utilize data points other than quoted prices in active markets that are observable either directly or indirectly. Fair values determined by Level 3 inputs utilize unobservable data points in which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts reflected in the consolidated balance sheets for cash equivalents, accounts payable and accrued expenses approximate their carrying value due to their short-term nature. There were no level 2 or level 3 assets or liabilities at March 31, 2021 or December 31, 2020.

9

7. Loss Per Share

Basic net loss per common share is computed by dividing the net loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed by dividing the net loss available to common stockholders by the weighted average number of common shares and other potential common shares then outstanding. Potential common shares consist of common shares issuable upon the assumed exercise of in-the-money stock options and warrants and potential common shares related to the conversion of the preferred stock. The computation of diluted net loss per share does not assume the issuance of common shares that have an anti-dilutive effect on net loss per share.

Dilutive shares which could exist pursuant to the exercise of outstanding stock instruments and which were not included in the calculation because their affect would have been anti-dilutive are as follows:

	March 31, 2021 (shares)		March 31, 2020 (shares)
Warrants to purchase shares of common stock		12,538,204		12,538,204
Options to purchase shares of common stock		5,762,575		3,737,575
Shares of common stock issuable upon conversion of preferred stock		510,424		514,602
		18,811,203		16,790,381

8. Common Stock

2020 At Market Issuance of Common Stock

On May 11, 2020, the Company entered into an At Market Issuance Sales Agreement (the “2020 At Market Agreement”) with a sales agent under which the Company may issue and sell shares of its common stock having an aggregate offering price of up to $40.0 million from time to time through the sales agent. Sales of the Company’s common stock through the sales agent, if any, will be made by any method that is deemed an “at the market” offering as defined by the U.S. Securities and Exchange Commission. The Company will pay to the sales agent a commission rate equal to 3.0% of the gross proceeds from the sale of any shares of common stock sold through the sales agent under the 2020 At Market Agreement. During the quarter ended March 31, 2021, there were no issuances of shares of common stock under the 2020 At Market Agreement.

For the three months ended March 31, 2021 and 2020, the Company has issued a total of 30,625 and 30,875 shares of common stock, respectively, for dividends on Series A and Series C Preferred Stock.

9. Commitments and Contingencies

Other Legal Proceedings

The Company records accruals for such contingencies to the extent that the Company concludes that their occurrence is probable and the related damages are estimable. There are no significant pending legal proceedings.

Clinical Trial and Research Commitments

The Company has entered into agreements with contractors for research and development activities to further its product candidates. The contracts generally may be canceled at any time by providing thirty days’ notice.

10. Leases

The Company has one operating lease for its office space which was amended effective January 1, 2019 for a term of 38 months with no residual value guarantees or material restrictive covenants. The amended lease provided for free rent for the first two months of the lease and continues the security deposit of $6,000. In addition to base rental payments included in the contractual obligations table above, the Company is responsible for our pro-rata share of the operating expenses for the building. Our lease cost for the three-month periods ended March 31, 2021 and 2020 was $11,000 for each period and is included in general and administrative expenses. As of March 31, 2021, the right to use lease asset consisted of $38,000 and is included in other assets. Also, at March 31, 2021, current lease liability of $42,000 is included in accrued expenses.

11. Galectin Sciences LLC

In January 2014, we created Galectin Sciences, LLC (the “LLC” or “Investee”), a collaborative joint venture co-owned by SBH Sciences, Inc. (“SBH”), to research and develop small organic molecule inhibitors of galectin-3 for oral administration. The LLC was initially capitalized with a $400,000 cash investment to fund future research and development activities, which was provided by the Company, and specific in-process research and development (“IPR&D”) contributed by SBH. The estimated fair value of the IPR&D contributed by SBH, on the date of contribution, was $400,000. Initially, the Company and SBH each had a 50% equity ownership interest in the LLC, with neither party having control over the LLC. Accordingly, from inception through the fourth quarter of 2014, the Company accounted for its investment in the LLC using the equity method of accounting. Under the equity method of accounting, the Company’s investment was initially recorded at cost with subsequent adjustments to the carrying value to recognize additional investments in or distributions from the Investee, as well as the Company’s share of the Investee’s earnings, losses and/or changes in capital. The estimated fair value of the IPR&D contributed to the LLC was immediately expensed upon contribution as there was no alternative future use available at the point of contribution. The operating agreement provides that if either party does not desire to contribute its equal share of funding required after the initial capitalization, then the other party, providing all of the funding, will have its ownership share increased in proportion to the total amount contributed from inception. In the fourth quarter of 2014, after the LLC had expended the $400,000 in cash, SBH decided not to contribute its share of the funding required. Since then, the Company has contributed a total of $2,456,000, including $57,000 for the three months ended March 31, 2021, for expenses of the LLC. Since the end of 2014, SBH has contributed $158,000 for expenses in the LLC. As of March 31, 2021, the Company’s ownership percentage in the LLC was 83.6%. The Company accounts for the interest in the LLC as a consolidated, less than wholly owned subsidiary. Because the LLC’s equity is immaterial, the value of the non-controlling interest is also deemed to be immaterial.

12. Subsequent Events

On April 16, 2021, Galectin Therapeutics Inc. (the “Company”) and Richard E. Uihlein, Chairman of our Board of Directors, entered into a debt financing arrangement whereby Mr. Uihlein loaned $10,000,000 to Company. In consideration for the loan, the Company issued a convertible promissory note (the “Note”) in the principal amount of ten million dollars.

The Note has a maturity date of April 16, 2025 and is convertible into the Company’s common stock at a conversion price equal to $5.00 per share at the option of the noteholder. The Note bears interest at the rate of two percent (2%) per annum, compounded annually, and accrues additional interest at a rate of two and one-half percent (2.5%) per quarter (the “Additional Interest”) beginning on the date of issuance of this Note and ending on the maturity date, provided however, that such Additional Interest is payable if and only if the noteholder elects to convert the entire balance of the Note into the Company’s common stock on or prior to maturity.

The following discussion should be read in conjunction with the accompanying consolidated financial statements and notes thereto of Galectin Therapeutics appearing elsewhere herein.

Overview

We are a clinical stage biopharmaceutical company engaged in drug research and development to create new therapies for fibrotic disease, cancer and selected other diseases. Our drug candidates are based on our method of targeting galectin proteins, which are key mediators of biologic and pathologic functions. We use naturally occurring, readily-available plant products as starting material in manufacturing processes to create proprietary, patented complex carbohydrates with specific molecular weights and other pharmaceutical properties. These complex carbohydrate molecules are appropriately formulated into acceptable pharmaceutical formulations. Using these unique carbohydrate-based candidate compounds that largely bind and inhibit galectin proteins, particularly galectin-3, we are undertaking the focused pursuit of therapies for indications where galectin proteins have a demonstrated role in the pathogenesis of a given disease. We focus on diseases with serious, life-threatening consequences and those where current treatment

12

options, are limited specifically in NASH (non-alcoholic steatohepatitis) with cirrhosis and certain cancer indications. Our strategy is to establish and implement clinical development programs that add value to our business in the shortest period of time possible and to seek strategic partners when one of our programs becomes advanced and requires significant additional resources.

Our lead galectin-3 inhibitor is belapectin (GR-MD-02), which has been demonstrated in preclinical models to reverse liver fibrosis and cirrhosis. Belapectin has the potential to treat many diseases due to galectin-3’s involvement in multiple key biological pathways such as fibrosis, immune cell function and immunity, cell differentiation, cell growth, and apoptosis (cell death). The importance of galectin-3 in the fibrotic process is supported by experimental evidence. Animals with the gene responsible for galectin-3 “knocked-out” can no longer develop fibrosis in response to experimental stimuli compared to animals with an intact galectin-3 gene. We are using our galectin-3 inhibitor to treat advanced liver fibrosis and liver cirrhosis in NASH patients. We have completed two Phase 1 clinical studies, a Phase 2 clinical study in NASH patients with advanced fibrosis (NASH-FX) and a second Phase 2b clinical trial in NASH patients with well compensated cirrhosis (NASH-CX) meaning the liver is scarred but still able to perform most of its basic functions.

We are now engaged in a Phase 2b/3 clinical trial. Our study protocol was filed with the FDA on April 30, 2020 for a seamless adaptively-designed Phase 2b/3 clinical study, the NAVIGATE trial (formerly called NASH-RX), evaluating the safety and efficacy of its galectin-3 inhibitor, belapectin (GR-MD-02), for the prevention of esophageal varices in patients with non-alcoholic steatohepatitis (NASH) cirrhosis (Further details are available at www.clinicaltrials.gov under study NCT04365868); this study began enrolling patients in Q2-2020. In September 2020, the Company received a letter from the FDA providing comments, asking questions and providing guidance on various aspects of the ongoing NAVIGATE trial.

Additionally, a study protocol entitled “A Single-dose, Open-label, Pharmacokinetic Study of Belapectin (GR-MD-02) in Subjects With Normal Hepatic Function and Subjects With Varying Degrees of Hepatic Impairment” has been filed with the FDA to examine the effects of the drug in subjects with normal hepatic function and subjects with varying degrees of hepatic impairment (study details are listed under study NCT04332432 on www.clinicaltrials.gov); this study is enrolling patients.

We endeavor to leverage our scientific and product development expertise as well as established relationships with outside sources to achieve cost-effective and efficient drug development. These outside sources, amongst others, provide us with expertise in preclinical models, pharmaceutical development, toxicology, clinical trial operations, pharmaceutical manufacturing, sophisticated physical and chemical characterization, and commercial development. We also have established through our majority-owned joint venture subsidiary, Galectin Sciences LLC, a discovery program aimed at the targeted development of small molecules (generally, non-carbohydrate) that bind galectin proteins and may afford options for alternative means of drug delivery (e.g., oral) and as a result expand the potential uses of our galectin-3 inhibitor compounds. Three series of composition of matter patents covering discoveries at Galectin Sciences have been filed.

We are also pursuing a development pathway to clinical enhancement and commercialization for our lead compounds in immuno-oncology for cancer therapy in collaboration with Providence Portland Cancer Center. However, our clinical development efforts are primarily focused on liver fibrosis and NASH. All of our proposed products are presently in development, including pre-clinical and clinical trials.

Our Drug Development Programs

Galectins are a class of proteins that are made by many cells in the body, but predominantly in cells of the immune system. As a group, these proteins are able to bind to sugar molecules that are part of other proteins, glycoproteins, in and on the cells of our body. Galectin proteins act as a kind of molecular glue, bringing together molecules that have sugars on them. Galectin proteins, in particular galectin-3, are known to be markedly increased in a number of important diseases including inflammatory diseases, scarring of organs (e.g. liver, lung, kidney, and heart) and cancers of many kinds. The increase in galectin protein promotes the disease and is detrimental to the patient. Published data substantiating the importance of galectin-3 in the fibrotic process arises from gene knockout experiments in animal studies. Mice genetically altered to eliminate the galectin-3 gene, and thus unable to produce galectin-3, are incapable of developing liver fibrosis in response to toxic insult to the liver and in fatty liver disease as well as development of fibrosis in other tissues.

We have one new proprietary chemical entity (NCE) in development, belapectin, which has shown promise in preclinical and early clinical studies in treatment of fibrosis, severe skin disease, and in cancer therapy. Currently we are focusing on development of belapectin intended to be used in the treatment of liver fibrosis associated with fatty liver disease (NASH) and more specifically in NASH cirrhosis. We have also leveraged our relationships with well-known investigators to demonstrate clinical effects of belapectin in treating moderate to severe plaque psoriasis, severe atopic dermatitis, and in cancer therapy in combination with immune-system modifying agent(s). Belapectin is a proprietary, patented compound derived from natural, readily available, plant-based starting materials, which, following chemical processing, exhibits the properties of binding to and inhibiting galectin-3 proteins. A second NCE, GM-CT-01 is a proprietary, patented compound that is made from a completely different starting source plant material and also binds and inhibits galectin proteins. Previously in clinical development for cancer indications, GM-CT-01 compound has been explored in limited other preclinical studies.

Fibrosis. Belapectin is our lead product candidate for treatment of fibrotic disease. Our preclinical data show that belapectin has a significant therapeutic effect on liver fibrosis as shown in several relevant animal models. In addition, in NASH animal models, belapectin has been shown to reduce liver fat, inflammation, and ballooning degeneration (death of liver cells). Therefore, we chose

14

belapectin as the lead candidate in a development program targeted initially at fibrotic liver disease associated with non-alcoholic steatohepatitis (NASH). In January 2013, an Investigational New Drug (“IND”) was submitted to the FDA with the goal of initiating a Phase 1 study in patients with NASH and advanced liver fibrosis to evaluate the human safety of belapectin and pharmacodynamics biomarkers of disease. On March 1, 2013, the FDA indicated we could proceed with a US Phase 1 clinical trial for belapectin with a development program aimed at obtaining support for a proposed indication of belapectin for treatment of NASH with advanced fibrosis. The Phase 1 trial was completed and demonstrated that belapectin up to 8 mg/kg Lean Body Mass (LBM), i.v. was safe and well tolerated.

Additionally, an open label drug-drug interaction study was completed in healthy volunteers during the second quarter of 2015 with belapectin and it showed that with 8 mg/kg LBM dose of belapectin and 2 mg/kg LBM dose of midazolam there was no drug-drug interaction and no serious adverse events or drug-related adverse events were observed. The secondary objective was to assess the safety and tolerability of belapectin when administered concomitantly with midazolam.

Our Phase 2 program in fibrotic disease consisted of two separate human clinical trials. The primary clinical trial was the Phase 2b NASH-CX study for one year for patients with NASH with compensated cirrhosis, which began enrolling in June 2015. This study was the primary focus of our program and was a randomized, placebo-controlled, double-blind, parallel-group Phase 2b trial to evaluate the safety and efficacy of belapectin for treatment of liver fibrosis and resultant portal hypertension in NASH patients with compensated cirrhosis. A smaller, exploratory NASH-FX trial was conducted to explore potential use of various non-invasive imaging techniques in NASH patients with advanced fibrosis but not cirrhosis.

NASH-FX Trial: The NASH-FX trial was a Phase 2a pilot trial for patients with NASH and advanced fibrosis that explored use of three non-invasive imaging technologies. It was a short, single site, four-month trial in 30 NASH patients with advanced fibrosis (F3), but not cirrhosis (F4), randomized 1:1 to either 9 bi-weekly doses of 8 mg/kg LBM of belapectin or placebo. The trial did not meet its primary biomarker endpoint as measured using multi-parametric magnetic resonance imaging (LiverMultiScan(R), Perspectum Diagnostics). The trial also did not meet secondary endpoints that measure liver stiffness as a surrogate for fibrosis using, magnetic resonance-elastography and FibroScan® score. We, and many experts in the field, now believe that a four-month treatment period was not sufficient to show efficacy results in established advanced liver fibrosis. This small study was also not adequately powered for the secondary endpoints. In the trial, belapectin was found to be safe and well tolerated with no serious adverse events and evidence of a pharmacodynamic effect. These results provided support for further development in NASH.

NASH-CX Trial: The NASH-CX trial was a larger multi-center clinical trial that explored the use of belapectin for the treatment of liver fibrosis and resultant portal hypertension in patients with well-compensated NASH cirrhosis. Enrollment in this trial was completed in September 2016, and a total of 162 patients at 36 sites in the United States were randomized to receive either 2 mg/kg LBM of belapectin, 8 mg/kg LBM of belapectin or placebo, with 54 patients in each group. Approximately 50% of patients at baseline had esophageal varices (a complication of portal hypertension). The primary endpoint was a reduction in hepatic venous pressure gradient (HVPG). Patients received an infusion of belapectin or placebo every other week for one year, a total of 26 infusions, and were evaluated to determine the change in HVPG as compared with placebo. Secondary or exploratory endpoints included fibrosis on liver biopsy, measurement of liver stiffness (FibroScan(R)) and assessment of liver metabolism (13C-methacetin breath test, Exalenz). Top line data readout was reported in December 2017. The study demonstrated a favorable safety profile and clinically meaningful efficacy results in patients without esophageal varices at baseline demonstrated by a prevention of development of varices when compared to placebo.

In the total patient population, the primary endpoint HVPG showed a trend toward benefit with belapectin treatment, but the difference from placebo was not statistically significant. The mean change in HVPG of placebo from baseline to week 54 was 0.3 mm Hg. The mean change in HVPG from baseline was -0.37 and -0.42 for the 2 mg/kg LBM dose and 8 mg/kg LBM dose of belapectin, respectively.

In those NASH cirrhosis patients without varices at baseline (about 50% of the total population), there was a statistically significant effect of the 2 mg/kg LBM dose of belapectin on the absolute change in HVPG (-1.08 mm Hg, p<0.01). The effect of the 8 mg/Kg LBM dose of belapectin on absolute or percent change in HVPG from baseline to week 54 was not significant.

Also because of the clinical relevance of this population, a responder analysis was performed on those patients without varices at baseline. Analysis was performed looking at two groups: those with an equal to or greater than 2 mm Hg decrease in HVPG from baseline or those with an equal to or greater than 2 mm Hg and a greater than or equal to 20% decrease in HVPG from baseline. In both cases, the change observed in the belapectin 2 mg/kg LBM group was statistically significant (p<0.01) while that of the 8 mg/kg LBM group was not.

Over the 54-week treatment period, in patients without varices there were statistically significantly fewer new varices that developed in the belapectin treatment groups (0% and 4% in the 2 mg/kg LBM and the 8 mg/kg LBM, respectively) vs placebo (18%). As esophageal varices can lead to hemorrhagic complication, which can be fatal, we believe the prevention of esophageal varices may represent a clinically relevant measure of clinical efficacy in patients with NASH cirrhosis.

15

The major conclusions from the NASH-CX trial results were that: i) belapectin had a statistically significant and clinically meaningful effect in improving HVPG vs placebo in patients with NASH cirrhosis who did not have esophageal varices at baseline. This effect was seen regardless of the patient’s baseline portal hypertension. ii) There was an important drug effect of belapectin in the total patient population on liver biopsy with a statistically significant improvement in hepatocyte ballooning (ie cell death), (iii) There was a statistically significant reduction (p=0.02) in the development of new esophageal varices in drug-treated patients compared to placebo. We believe that this is a clinically relevant endpoint related to patient outcomes, (iv) While there was a drug effect in both the 2 mg/kg LBM and 8 mg/kg LBM groups on the development of varices and liver biopsy there was a consistently greater and statistically significant effect of the 2 mg/kg LBM dose of belapectin, (v) belapectin appears to be safe and well tolerated in this one year clinical trial, a feature that is of prime importance for a cirrhotic population and (vi) We believe this is the first large, randomized clinical trial to demonstrate a clinically meaningful improvement in portal hypertension or liver biopsy in patients with compensated NASH cirrhosis who have not yet developed esophageal varices.

Further information and details on the NASH-CX results summarized above is available in public presentations posted to our website and filed with the SEC and in a peer reviewed publication in Gastroenterology (Gastroenterology 2020;158:1334–1345).

NASH NAVIGATE Trial: Building on the experience of the NASH-CX trial, the NAVIGATE Trial is a seamless adaptively-designed Phase 2b/3 clinical study evaluating the safety and efficacy of our galectin-3 inhibitor, belapectin (GR-MD-02), for the prevention of esophageal varices in patient with non-alcoholic steatohepatitis (NASH) cirrhosis. The major features of this innovative Phase 2b/3 study design are: i) In patients with NASH cirrhosis and clinical signs of portal hypertension but without esophageal varices at baseline, this trial will assess the effect of belapectin on the incidence of new varices (the primary endpoint) – as well as assessing effect on the incidence of long-term, clinically significant cirrhosis-related outcomes (a key secondary efficacy endpoint), (ii) The study targets NASH patients with a clearly identified unmet medical need: patients with compensated cirrhosis who are at risk of developing esophageal varices, a potentially life-threatening complication of cirrhosis (bleeding varices are a cause of death in about one-third of cirrhotic patients). There is no approved treatment for preventing varices in these patients. In addition, the development of esophageal varices reflects the progression of hepatic cirrhosis and thus portends the development of other cirrhosis complications such as ascites, hepatic encephalopathy, and liver failure, and (iii) During the first 18 months, two belapectin dose levels (2 mg/kg LBM and 4 mg/kg LBM) will be compared to placebo (phase 2b). Then, at the interim analysis (IA), one belapectin dose will be selected based on efficacy and safety, for continued evaluation (Phase 3). The belapectin dose selected for the phase 2b/3 are based on the analysis of the NASH-CX trial, including a dose response pharmacokinetic analysis of the hepatic venous gradient pressure (HVPG, a reflection of portal hypertension). Prior belapectin clinical studies have also indicated the good tolerance and safety profile of belapectin with doses of up to 8 mg/kg LBM for 52 weeks (Phase 2b Study NASH-CX), an important feature of the future risk benefit analysis in patients with NASH cirrhosis.

The study design provides for a pre-specified interim analysis (IA). The IA of efficacy and safety data will be conducted after all planned subjects in Phase 2b component have completed at least 78 weeks (18 months) of treatment and an esophago-gastro-duodeno endoscopic assessment. The purpose of the IA is to allow potential seamless adaptive modifications of the study, including: (1) the selection of the optimal dose of belapectin for Phase 3, (2) the re-estimation of the study sample size for Phase 3 portion of the trial, (3) the re-evaluation of the randomization ratio for the Phase 3 portion of the trial, (4) the refinement of the inclusion and exclusion criteria for the Phase 3 portion of the trial, including the cirrhosis status, (5) and/or termination of the study for overwhelming efficacy or for futility.

The trial design also includes a blinded sample size re-estimation (“SSR”) during the Phase 2b, prior to the IA, to allow for potential sample size readjustment. The SSR will be conducted when 50% of the patients have completed 18 months of therapy. This will allow us to confirm the underlying assumption regarding the rate of varices development, currently estimated from our prior Phase 2b trial (NASH-CX). The study design also minimizes invasive testing requirements, such as the measurement of HVPG or repeated liver biopsies, which we believe will facilitate enrollment and retention of patients. It also provides for a seamless transition of patients from the Phase 2b component into the phase 3 stage, including the potential addition of new patients. The trial design preserves the surrogate end-point concepts (development of new varices versus variceal hemorrhage) previously discussed with FDA.

We believe that these adaptations taken together are innovative and optimize conduct of the NAVIGATE trial with a clinically relevant primary outcome giving belapectin the best opportunity to show a positive therapeutic effect to address an unmet medical need. If the IA results of the NAVIGATE trial are compelling, there could be the potential for accelerated FDA approval and/or partnership opportunity with a pharmaceutical company.

In the Phase 3 component of this trial, as proposed in the protocol, the primary endpoint remain the development of varices. Secondary endpoints include a composite clinical outcomes endpoint, including varices requiring treatment (development of large varices or varices with a red wale), decompensating events, all-cause mortality, MELD score increase, liver transplant. Also, NASH

16

non-invasive biomarkers will be evaluated. To target a population at risk of developing esophageal varices, patient selection will be based on clinical signs of portal hypertension, including, a low platelet count, an increased spleen size and/or evidence of collaterals circulation.

The focus and goal of the therapeutic program is to stop the progression of and/or reverse portal hypertension and thereby prevent the development of varices, potentially one of the most immediately life-threatening complication of cirrhosis. Based on the results of the NASH-CX trial and subject to confirmation in later stage clinical trials, we believe that this goal is achievable in a significant portion of the NASH cirrhosis patient population i.e. those NASH cirrhosis patients with clinical signs of portal hypertension.

The COVID-19 pandemic has delayed and may continue to delay our recruitment of sites and enrollment of patients for our Phase 2b/3 NAVIGATE trial despite a recent uptick in screening activities. Many cities in the United States and Europe have experienced shut-downs, and while some cities have begun to loosen restrictions, they are at risk of experiencing new shut-downs and restrictions. In some countries, shutdown orders have also affected the regulatory process to authorize study starts. Governments and medical facilities are focusing their resources for battling the COVID-19 pandemic. For several reasons, the pandemic makes enrolling patients for the NAVIGATE trial more challenging, including because patients eligible for the NAVIGATE trial have liver cirrhosis and, as such, are at a greater health risk of complications from COVID-19 until vaccinations are more readily available and completed. We believe that as more people get vaccinated for COVID-19, site recruitment and patient enrollment will accelerate. At this time, we estimate that enrollment completion will occur by the end of 2022.

We have identified more than 130 clinical trial sites in 11 countries for the NAVIGATE trial.

Further details on the NAVIGATE trial can be found on www.clinicaltrials.gov under study NCT04365868.

The Company also has commenced a Hepatic Impairment Study, which will run in parallel with the phase 2b/3 trial as part of the development program. The Hepatic Impairment Study is being conducted at three sites and will involve approximately 40 patients (divided amongst normal healthy volunteers, and patients with hepatic impairment categorized as Child-Turcotte-Pugh (CTP) classes A (mild), B (moderate), and C (severe)). Each subject will receive a single infusion of belapectin (4 mg/kg LBM) and their serum belapectin levels will be monitored for up to approximately two weeks to define the effects of various stages of cirrhosis on serum belapectin levels. The tolerance and safety of belapectin will be evaluated. Based on the results from this hepatic impairment study, the Company may consider including patients with more advanced cirrhosis in the Phase 3 portion of its NAVIGATE trial. Until dosing and safety profile is further informed in CTP Class B and/or Class C patients, the NAVIGATE trial will enroll only CTP Class A patients. Further details on this hepatic impairment study can be found on www.clinicaltrials.gov study NCT04332432.

Cancer Immunotherapy. We believe there is potential for galectin inhibition to play a key role in the burgeoning area of cancer immunotherapy. For example, there have been several recent approvals of drugs that enhance a patient’s immune system to fight cancer. It is our goal to use a galectin inhibitor to further enhance the immune system function to fight cancer in a way that complements other approaches to this type of therapy. This hypothesis is supported by the fact that galectin-3 is expressed at high levels in multiple types of tumors, adds to the malignant nature of the tumors, and protects the tumors from immune system attack. Our drug candidates provide a promising new therapeutic approach to enhance the activity of the immune system against cancer cells. Preclinical studies have indicated that belapectin enhances the immune response to cancer cells, increased tumor shrinkage and enhanced survival in immune competent mice with prostate, breast, melanoma and sarcoma cancers when combined with one of the immune checkpoint inhibitors, anti-CTLA-4 or anti-PD-1, or with the immune cell activator anti-OX40. These preclinical data led to the filing of two Investigator-sponsored INDs and the initiation of studies of belapectin in combination with Yervoy® (ipilimumab) and KEYTRUDA (pembrolizumab) in Phase 1B studies of patients with metastatic melanoma. The KEYTRUDA trial has also been expanded to include patients with non-small cell lung cancer and head and neck squamous cell carcinoma. These studies are being conducted under the sponsorship of Providence Portland Medical Center’s Earle A. Chiles Research Institute (EACRI).

Promising results were reported in the Phase 1b trial combining belapectin with pembrolizumab (KEYTRUDA®). Cohort 1 was completed (n=6, 5 with melanoma, one with head and neck cancer) with one partial response and one mixed response in the melanoma patients. There was a rapid and marked tumor response after 3 doses of combined belapectin and pembrolizumab in the one partial response patient who had failed high-dose IL-2 and oncolytic virus + ipilimumab. The study is ongoing and progression to further development will be based on response rate as compared to historical response rates to pembrolizumab alone. In September 2018 we announced additional preliminary clinical data from cohort 3 of this investigator-initiated trial. When aggregated with cohorts previously reported, the data shows a 50% objective response rate in advanced melanoma with belapectin in combination with KEYTRUDA, and a significant decrease in the frequency of suppressive myeloid-derived suppressor cells following treatment in the responding patients (on day 85 post-treatment). Fourteen advanced melanoma patients across three dose cohorts now have Objective Response Rate (ORR) and Disease Control Rate (DCR) data. Six patients completed in cohort 3 (8 mg/kg LBM) have now been added to the three patients completed in cohort 2 (4 mg/kg LBM) and five patients completed in cohort 1 (2 mg/kg LBM). Cohorts 1 and 3 each had two patients with an objective response. All three patients in cohort 2 had an objective response. In addition to the fourteen

17

advanced melanoma patients, six patients with head and neck cancer were enrolled in this trial with a 33% ORR and 67% DCR. These data, taken together with the observed favorable safety and tolerability of the combination, in the view of the principal investigator, provide compelling rationale to move forward. Given that all three melanoma patients were responders at the 4 mg/kg dose, the investigators plan to continue the trial with the expansion of the 4 mg/Kg cohort to include additional advanced melanoma patients and additional head and neck cancer patients. The expansion cohort includes 14 patients and is planned to have continued belapectin dosing to match the recommended duration of pembrolizumab administration. The expansion cohort has been enrolled and further information will be reported as it becomes available. Discussions are ongoing about the planning and feasibility of a multicenter Phase 2 study, assuming the additional expansion cohort data are positive.

Research and Development Expense.

	Three Months Ended March 31,				2021 as Compared to 2020 Three Months
	2021		2020		$ Change		% Change
	(In thousands, except %)
Research and development	$	4,899	$	2,144	$	2,755		128	%

We generally categorize research and development expenses as either direct external expenses, comprised of amounts paid to third party vendors for services, or all other research and development expenses, comprised of employee payroll and general overhead allocable to research and development. We consider a clinical program to have begun upon acceptance by the FDA, or similar agency outside of the United States, to commence a clinical trial in humans, at which time we begin tracking expenditures by the product candidate. Clinical program expenses comprise payments to vendors related to preparation for, and conduct of, all phases of the clinical trial, including costs for drug manufacture, patient dosing and monitoring, data collection and management, oversight of the trials and reports of results. Pre-clinical expenses comprise all research and development amounts incurred before human trials begin, including payments to vendors for services related to product experiments and discovery, toxicology, pharmacology, metabolism and efficacy studies, as well as manufacturing process development for a drug candidate.

Our research and development expenses were as follows:

	Three Months Ended March 31,
	2021		2020
	(in thousands)
Direct external expenses:
Clinical activities	$	4,283	$	1,019
Pre-clinical activities		111		243
All other research and development expenses		505		882
	$	4,899	$	2,144

Clinical programs expenses increased primarily due to costs related to our NAVIGATE trial during the three months ended March 31, 2021. Other research and development expense decreased primarily due to a decrease in non-cash stock-based compensation expense.

Both the time required and costs we may incur in order to commercialize a drug candidate that would result in material net cash inflow are subject to numerous variables, and therefore we are unable at this stage of our development to forecast useful estimates. Variables that make estimates difficult include the number of clinical trials we may undertake, the number of patients needed to participate in the clinical trial, patient recruitment uncertainties, trial results as to the safety and efficacy of our product, and uncertainties as to the regulatory agency response to our trial data prior to receipt of marketing approval. Moreover, the FDA or other regulatory agencies may suspend clinical trials if we or an agency believes patients in the trial are subject to unacceptable risks or find deficiencies in the conduct of the clinical trial. Delays or rejections may also occur if governmental regulation or policy changes during our clinical trials or in the course of review of our clinical data. Due to these uncertainties, accurate and meaningful estimates of the ultimate cost to bring a product to market, the timing of costs and completion of our program and the period during which material net cash inflows will commence are unavailable at this time.

General and Administrative Expense.

	Three Months Ended March 31,				2021 as Compared to 2020 Three Months
	2021		2020		$ Change			% Change
	(In thousands, except %)
General and administrative	$	1,418	$	1,440	$	(22	)		(2	)%

General and administrative expenses consist primarily of salaries including stock-based compensation, legal and accounting fees, insurance, investor relations, business development and other office related expenses. The primary reasons for the decrease in general and administrative expenses for the three-months ended March 31, 2021 as compared to the same period in 2020 are due to a decrease in investor relations/business development expenses of approximately $73,000 and a decrease in non-cash stock based compensation expenses of approximately $86,000, partially offset by an increase in insurance expense of $124,000.

Liquidity and Capital Resources

Since our inception on July 10, 2000, we have financed our operations from proceeds of public and private offerings of debt and equity. As of March 31, 2021, we raised a net total of $197.7 million from these offerings. We have operated at a loss since our inception and have had no significant revenues. We anticipate that losses will continue for the foreseeable future. At March 31, 2021, the Company had $20.8 million of unrestricted cash and cash equivalents available to fund future operations. On April 16, 2021, the Company received $10 million in proceeds from a convertible promissory note. The Company also has a $10 million unsecured line of credit facility with stockholder and director, Richard E. Uihlein. The Company has not drawn under the line of credit. The Company believes there is sufficient cash, including availability of the line of credit, to fund currently planned operations at least through September 30, 2022. We will require more cash to fund our operations after September 30, 2022 and believe we will be able to obtain additional financing. 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 $35-$40 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. 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.

Net cash used in operations increased by $2,011,000 to $6,382,000 for the three months ended March 31, 2021, as compared to $4,371,000 for the three months ended March 31, 2020. Cash operating expenses increased principally due to the preparations and expenses related to our NAVIGATE clinical trial with belapectin.

Net cash provided by financing activities for the three months ended March 31, 2020, of $219,000 represents proceeds from the exercise of common stock options.

Off-Balance Sheet Arrangements

We have not created, and are not a party to, any special-purpose or off-balance sheet entities for the purpose of raising capital, incurring debt or operating parts of our business that are not consolidated into our financial statements. We do not have any arrangements or relationships with entities that are not consolidated into our financial statements that are reasonably likely to materially affect our liquidity or the availability of capital resources.

Application of Critical Accounting Policies and Estimates

The preparation of condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to accrued expenses, stock-based compensation, contingencies and litigation. We base our estimates on historical experience, terms of existing contracts, our observance of trends in the industry, information available from other outside sources and on various other factors that we believe to be appropriate under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

Critical accounting policies are those policies that affect our more significant judgments and estimates used in preparation of our consolidated financial statements. We believe our critical accounting policies include our policies regarding stock-based compensation, accrued expenses and income taxes. For a more detailed discussion of our critical accounting policies, please refer to our 2020 Annual Report on Form 10-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact our financial position, operating results or cash flows due to changes in the U.S. interest rates. The primary objective of our investment activities is to preserve cash until it is required to fund operations. To minimize risk, we maintain our portfolio of cash and cash equivalents in operating bank accounts and money market funds. Since our investments are short-term in duration, we believe that we are not subject to any material market risk exposure.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of the Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934) and concluded that, as of March 31, 2021, our disclosure controls and procedures were effective.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.

Changes in Internal Control Over Financial Reporting

During the quarter ended March 31, 2021, no change in our internal control over financial reporting has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

1. Basis of Presentation

Galectin Therapeutics Inc. and subsidiaries (the “Company”) is a clinical stage biopharmaceutical company that is applying its leadership in galectin science and drug development to create new therapies for fibrotic disease and cancer. These candidates are based on the Company’s targeting of galectin proteins which are key mediators of biologic and pathologic function. These compounds also may have application for drugs to treat other diseases and chronic health conditions.

The unaudited condensed consolidated financial statements as reported in this Quarterly Report on Form 10-Q reflect all adjustments which are, in the opinion of management, necessary to present fairly the financial position of the Company as of March 31, 2021 and the results of its operations for the three months ended March 31, 2021 and 2020 and its cash flows for the three months ended March 31, 2021 and 2020. All adjustments made to the interim financial statements include all those of a normal and recurring nature. Amounts presented in the condensed consolidated balance sheet as of December 31, 2020 are derived from the Company’s audited consolidated financial statements as of that date, but do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date these financial statements are available to be issued. The results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. The unaudited condensed consolidated financial statements of the Company should be read in conjunction with its Annual Report on Form 10-K for the year ended December 31, 2020.

The Company has operated at a loss since its inception and has had no revenues. The Company anticipates that losses will continue for the foreseeable future. At March 31, 2021, the Company had $20,760,000 of unrestricted cash and cash equivalents available to fund future operations. On April 16, 2021, the Company received $10,000,000 in proceeds from a convertible promissory note (see Note 12). The Company believes there is sufficient cash, including availability of the line of credit (see Note 3), to fund currently planned operations at least through September 30, 2022. We will require more cash to fund our operations after September 30, 2022 and believe we will be able to obtain additional financing. 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 $35-$40 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. 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. If we are unsuccessful in raising additional capital to fund operations before September 30, 2022, we may be required to cease operations. Accordingly, based on the forecasts and estimates underlying our current operating plan, the financial statements do not currently include any adjustments that might be necessary if we are unable to continue as a going concern.

The Company was founded in July 2000, was incorporated in the State of Nevada in January 2001 under the name “Pro-Pharmaceuticals, Inc.,” and changed its name to “Galectin Therapeutics Inc.” on May 26, 2011.

Research and development expenses, including personnel costs, allocated facility costs, lab supplies, outside services, contract laboratory costs related to manufacturing drug product, clinical trials and preclinical studies are charged to research and development expense as incurred. The Company accounts for nonrefundable advance payments for goods and services that will be used in future research and development activities as expense when the service has been performed or when the goods have been received. Our current NAVIGATE clinical trial is being supported by third-party contract research organizations, or CROs, and other vendors. We accrue expenses for clinical trial activities performed by CROs based upon the estimated amount of work completed on each trial. For

clinical trial expenses and related expenses associated with the conduct of clinical trials, the significant factors used in estimating accruals include the number of patients enrolled, the number of active clinical sites, and the duration for which the patients have been enrolled in the trial. We monitor patient enrollment levels and related activities to the extent possible through internal reviews, review of contractual terms and correspondence with CROs. We base our estimates on the best information available at the time. We monitor patient enrollment levels and related activities to the extent possible through discussions with CRO personnel and based our estimates of clinical trial costs on the best information available at the time. However, additional information may become available to us which will allow us to make a more accurate estimate in future periods. In that event, we may be required to record adjustments to research and development expenses in future periods when the actual level of activity becomes more certain.

Line of Credit

3. Line of Credit

The Company has a $10 million Line of Credit arrangement with Richard E. Uihlein, a director and shareholder pursuant to an agreement established in December, 2017 and amended in December, 2018 and January, 2019. Under the arrangement the Company may borrow up to $10 million from Mr. Uihlein on an unsecured basis and with any borrowings bearing interest at the Applicable Federal Rate for short terms loans published by the Internal Revenue Service (0.14% in January 2021). Borrowings may be made through December 31, 2021 with repayment due on December 31, 2022. In connection with the Line of Credit agreement, the Company issued to Mr. Uihlein warrants to purchase 1 million shares of the Company’s common stock for $5 per share. Half of the warrants vested at closing of the Line of Credit and the other half vest ratably with borrowings under the agreement. The 500,000 warrants that vested at closing were exercised in May 2019 for cash proceeds to the Company of $2.5 million. As of the date of this Quarterly Report, there have been no borrowings under the Line of Credit.

The fair value of the 500,000 warrants vested at closing in December 2017 was $696,000 at the date of issuance based on the following assumptions: an expected life of 7 years, volatility of 98%, risk free interest rate of 2.05% and zero dividends. The fair value of the vested warrants was recorded in other current assets and other assets (non-current) as a deferred financing cost and were to be amortized on a straight-line basis from December 19, 2017 through December 31, 2019. The remaining unamortized balance of the deferred financing cost on January 11, 2019 was adjusted to be recorded as expense on a straight-line basis through December 31, 2022. Amortization for the three months ended March 31, 2021 and 2020 of $22,000 and $22,000, respectively, was recorded as interest expense. The fair value of warrants that vest in the future based on borrowings will be computed when those borrowings occur and amortized over the remaining period through December 31, 2022 reflecting the second extension.

General and administrative		187		273
Total stock-based compensation expense	$	254	$	430

The following table summarizes the stock option activity in the Company’s equity incentive plans, including non-plan grants to Company executives, from December 31, 2020 through March 31, 2021:

	Shares			Weighted Average Exercise Price

As of March 31, 2021, there was $3,781,000 of unrecognized compensation related to 2,415,834 unvested options, which is expected to be recognized over a weighted–average period of approximately 2.3 years. The weighted-average grant date fair value for options granted during the three months ended March 31, 2021 was $1.56. The Company granted 1,865,000 stock options during the three months ended March 31, 2021. During the three months ended March 31, 2021, 70,000 stock options were exercised on a net basis resulting in the issuance of 46,282 shares of common stock.

The fair value of all other options granted is determined using the Black-Scholes option-pricing model. The following weighted average assumptions were used:

	Three Months Ended March 31,			Three Months Ended March 31,
	2021			2020
Risk-free interest rate		0.54	%		1.55	%
Expected life of the options		6 years			6 years
Expected volatility of the underlying stock		91	%		100	%
Expected dividend rate		0	%		0	%

In January 2020, two directors elected to take restricted stock grants in lieu of cash retainers for 2020. A total of 32,693 shares of restricted stock valued at approximately $93,500 is being amortized to expense on a straight-line basis until January 9, 2021 when the stock vests in full.

In March 2021, one director elected to take a restricted stock grant in lieu of cash retainers for 2021. A total of 16,588 shares of restricted stock valued at approximately $35,000 is being amortized to expense on a straight-line basis until December 31, 2021 when the stock vests in full.

In September 2020, the Company entered into an employment agreement with its new Chief Executive Officer whereby 20% of his base salary and performance bonuses will be paid in cash, and 80% will be paid in the form of deferred stock units (“DSUs”) in accordance with the terms and subject to the provisions set forth in the DSU Agreement. DSUs credited to Mr. Lewis as of any date shall be fully vested and nonforfeitable at all times. The Company shall issue the shares underlying the outstanding whole number of DSUs credited to Mr. Lewis as follows: twenty five percent shall be issued on March 1, 2023, twenty five percent shall be issued on September 1, 2023 and fifty percent shall be issued on March 1, 2024. For the three months ended March 31, 2021, approximately $100,000 of his compensation was recorded as stock compensation expense representing 44,593 shares of common stock to be issued under the DSU agreement with a weighted average grant date fair value of $2.24 per share. Also, Mr. Lewis’ bonus for the year ended December 31, 2020 of $60,000 (which was included in accrued compensation at December 31, 2020) was approved in March 2021 and represents 27,027 shares of common stock to be issued under the DSU agreement with a grant date fair value of $2.22 per share. The $60,000 was reclassified from accrued compensation to additional paid in capital in March 2021. There is no unrecognized compensation expense related to the DSUs.

6. Fair Value of Financial Instruments

The Company has certain financial assets and liabilities recorded at fair value. Fair values determined by Level 1 inputs utilize observable data such as quoted prices in active markets. Fair values determined by Level 2 inputs utilize data points other than quoted prices in active markets that are observable either directly or indirectly. Fair values determined by Level 3 inputs utilize unobservable data points in which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts reflected in the consolidated balance sheets for cash equivalents, accounts payable and accrued expenses approximate their carrying value due to their short-term nature. There were no level 2 or level 3 assets or liabilities at March 31, 2021 or December 31, 2020.

Loss Per Share

7. Loss Per Share

Basic net loss per common share is computed by dividing the net loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed by dividing the net loss available to common stockholders by the weighted average number of common shares and other potential common shares then outstanding. Potential common shares consist of common shares issuable upon the assumed exercise of in-the-money stock options and warrants and potential common shares related to the conversion of the preferred stock. The computation of diluted net loss per share does not assume the issuance of common shares that have an anti-dilutive effect on net loss per share.

Dilutive shares which could exist pursuant to the exercise of outstanding stock instruments and which were not included in the calculation because their affect would have been anti-dilutive are as follows:

	March 31, 2021 (shares)		March 31, 2020 (shares)
Warrants to purchase shares of common stock		12,538,204		12,538,204

Galectin Sciences LLC

11. Galectin Sciences LLC

In January 2014, we created Galectin Sciences, LLC (the “LLC” or “Investee”), a collaborative joint venture co-owned by SBH Sciences, Inc. (“SBH”), to research and develop small organic molecule inhibitors of galectin-3 for oral administration. The LLC was initially capitalized with a $400,000 cash investment to fund future research and development activities, which was provided by the Company, and specific in-process research and development (“IPR&D”) contributed by SBH. The estimated fair value of the IPR&D contributed by SBH, on the date of contribution, was $400,000. Initially, the Company and SBH each had a 50% equity ownership interest in the LLC, with neither party having control over the LLC. Accordingly, from inception through the fourth quarter of 2014, the Company accounted for its investment in the LLC using the equity method of accounting. Under the equity method of accounting, the Company’s investment was initially recorded at cost with subsequent adjustments to the carrying value to recognize additional investments in or distributions from the Investee, as well as the Company’s share of the Investee’s earnings, losses and/or changes in capital. The estimated fair value of the IPR&D contributed to the LLC was immediately expensed upon contribution as there was no alternative future use available at the point of contribution. The operating agreement provides that if either party does not desire to contribute its equal share of funding required after the initial capitalization, then the other party, providing all of the funding, will have its ownership share increased in proportion to the total amount contributed from inception. In the fourth quarter of 2014, after the LLC had expended the $400,000 in cash, SBH decided not to contribute its share of the funding required. Since then, the Company has contributed a total of $2,456,000, including $57,000 for the three months ended March 31, 2021, for expenses of the LLC. Since the end of 2014, SBH has contributed $158,000 for expenses in the LLC. As of March 31, 2021, the Company’s ownership percentage in the LLC was 83.6%. The Company accounts for the interest in the LLC as a consolidated, less than wholly owned subsidiary. Because the LLC’s equity is immaterial, the value of the non-controlling interest is also deemed to be immaterial.

On April 16, 2021, Galectin Therapeutics Inc. (the “Company”) and Richard E. Uihlein, Chairman of our Board of Directors, entered into a debt financing arrangement whereby Mr. Uihlein loaned $10,000,000 to Company. In consideration for the loan, the Company issued a convertible promissory note (the “Note”) in the principal amount of ten million dollars.

The Note has a maturity date of April 16, 2025 and is convertible into the Company’s common stock at a conversion price equal to $5.00 per share at the option of the noteholder. The Note bears interest at the rate of two percent (2%) per annum, compounded annually, and accrues additional interest at a rate of two and one-half percent (2.5%) per quarter (the “Additional Interest”) beginning on the date of issuance of this Note and ending on the maturity date, provided however, that such Additional Interest is payable if and only if the noteholder elects to convert the entire balance of the Note into the Company’s common stock on or prior to maturity.
