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.</div> <div style="font-family: 'Times New Roman'; font-size: 10pt;"><br/> </div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;">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.</div> <div style="font-family: 'Times New Roman'; font-size: 10pt;"><br/> </div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="background-color: rgb(255, 255, 255); font-weight: normal; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-size: 10pt; font-style: normal; font-variant: normal; text-transform: none;">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 December 31, 2023, the company had $25,660,000 of unrestricted cash and cash equivalents available to fund future operations. In July 2022, the Company entered into a $60 million unsecured line of credit financing, of which $20 million remains available at December 31, 2023, with its chairman, Richard E. Uihlein (See Note 10). Additionally, on March 29, 2024, the Company entered into a supplemental unsecured $10 million line of credit financing also provided by our chairman (See Note 15). The Company believes there is sufficient cash, including availability of the line of credit, to fund currently planned operations at least through March 31, 2025. To meet its future capital needs, the Company intends to raise additional capital through debt or equity financings, collaborations, partnerships or other strategic transactions. However, there can be no assurance that the Company will be able to complete any such transactions on acceptable terms or otherwise. The inability of the Company to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on the Company’s business, results of operations and financial condition. The Company has the ability to delay certain research activities and related clinical expenses if necessary due to liquidity concerns until a date when those concerns are relieved.</span></div> <div style="font-family: 'Times New Roman'; font-size: 10pt;"><br/> </div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;">The Company is subject to a number of risks similar to those of clinical stage companies, including dependence on key individuals, uncertainty of product development and generation of revenues, dependence on outside sources of capital, risks associated with clinical trials of products, dependence on third-party collaborators for research operations, need for regulatory approval of products, risks associated with protection of intellectual property, and competition with larger, better-capitalized companies. Successful completion of the Company’s development program and, ultimately, the attainment of profitable operations is dependent upon future events, including obtaining adequate financing to fulfill its development activities and achieving a level of revenues adequate to support the Company’s cost structure. There are no assurances that the Company will be able to obtain additional financing on favorable terms, or at all, or successfully market its products.</div> 25660000 60000000 20000000 10000000 <table cellpadding="0" cellspacing="0" class="DSPFListTable" style="font-family: 'Times New Roman'; font-size: 10pt; width: 100%; text-align: left; color: #000000;"> <tr> <td style="width: 27.05pt; vertical-align: top; font-weight: bold;">2.</td> <td style="width: auto; vertical-align: top;"> <div style="font-weight: bold;">Summary of Significant Accounting Policies</div> </td> </tr> </table> <div style="font-family: 'Times New Roman'; font-size: 10pt;"><br/> </div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;">The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”).</div> <div style="font-family: 'Times New Roman'; font-size: 10pt;"><br/> </div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman'; font-style: italic;">Basis of Consolidation.</span><span style="font-family: 'Times New Roman';"> The consolidated financial statements include the accounts of the Company and Galectin Therapeutics Security Corp., its wholly-owned subsidiary, which was incorporated in Delaware on December 23, 2003 and Galectin Sciences LLC (see Note 13).

Recoverability of assets to be held or used is measured by comparison of the carrying value of the asset to the future undiscounted net cash flows expected to be generated by the asset. If such asset is considered to be impaired, the impairment recognized is measured by the amount by which the carrying value of the asset exceeds the discounted future cash flows expected to be generated by the asset.

As part of the process of preparing our consolidated financial statements, we are required to estimate accrued expenses. This process involves identifying services that third parties have performed on our behalf and estimating the level of service performed and the associated cost incurred on these services as of each balance sheet date in our consolidated financial statements. Examples of estimated accrued expenses include professional service fees, such as those arising from the services of attorneys and accountants and accrued payroll expenses. In connection with these service fees, our estimates are most affected by our understanding of the status and timing of services provided relative to the actual services incurred by the service providers. In the event that we do not identify certain costs that have been incurred or we under- or over-estimate the level of services or costs of such services, our reported expenses for a reporting period could be understated or overstated. The date on which certain services commence, the level of services performed on or before a given date, and the cost of services are often subject to our judgment. We make these judgments based upon the facts and circumstances known to us in accordance with accounting principles generally accepted in the U.S.</span></div> <div style="font-family: 'Times New Roman'; font-size: 10pt;"><br/> </div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman'; font-style: italic;">Warrants.</span><span style="font-family: 'Times New Roman';"> The Company has issued common stock warrants in connection with the execution of certain equity and debt financings. The fair value of warrants is determined using the Black-Scholes option-pricing model using assumptions regarding volatility of our common share price, remaining life of the warrant, and risk-free interest rates at each period end.

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.</span></div> <div style="font-family: 'Times New Roman'; font-size: 10pt;"><br/> </div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman'; font-style: italic;">Income Taxes.</span><span style="font-family: 'Times New Roman';"> The Company accounts for income taxes in accordance with the accounting rules that requires an asset and liability approach to accounting for income taxes based upon the future expected values of the related assets and liabilities. Deferred income tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and for tax loss and credit carry forwards and are measured using the expected tax rates estimated to be in effect when such basis differences reverse. Valuation allowances are established, if necessary, to reduce the deferred tax asset to the amount that will, more likely than not, be realized.</span></div> <div style="font-family: 'Times New Roman'; font-size: 10pt;"><br/> </div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman'; font-style: italic;">Concentration of Credit Risk.</span><span style="font-family: 'Times New Roman';"> Financial instruments that subject the Company to credit risk consist of cash and cash equivalents. The Company maintains cash and cash equivalents and certificates of deposit with well-capitalized financial institutions. At times, those amounts may exceed federally insured limits.

For awards that have performance-based vesting conditions the Company recognizes the expense over the estimated period that the awards are expected to be earned. The Company generally uses the Black-Scholes option-pricing model to calculate the grant date fair value of stock options. The expense recognized over the service period is required to include an estimate of the awards that will be forfeited.</span></div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman';"> <br/> </span></div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-size: 10pt; font-family: 'Times New Roman'; font-style: italic;">Recent Accounting Standards. </span>In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The new standard also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis, with early adoption permitted beginning on January 1, 2021. The Company adopted ASU 2020-06 effective January 1, 2022. The adoption of ASU 2020-06 did not have an impact on the Company’s financial statements.

This process involves identifying services that third parties have performed on our behalf and estimating the level of service performed and the associated cost incurred on these services as of each balance sheet date in our consolidated financial statements. Examples of estimated accrued expenses include professional service fees, such as those arising from the services of attorneys and accountants and accrued payroll expenses. In connection with these service fees, our estimates are most affected by our understanding of the status and timing of services provided relative to the actual services incurred by the service providers. In the event that we do not identify certain costs that have been incurred or we under- or over-estimate the level of services or costs of such services, our reported expenses for a reporting period could be understated or overstated. The date on which certain services commence, the level of services performed on or before a given date, and the cost of services are often subject to our judgment. We make these judgments based upon the facts and circumstances known to us in accordance with accounting principles generally accepted in the U.S.</span></div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman'; font-style: italic;">Warrants.</span><span style="font-family: 'Times New Roman';"> The Company has issued common stock warrants in connection with the execution of certain equity and debt financings. The fair value of warrants is determined using the Black-Scholes option-pricing model using assumptions regarding volatility of our common share price, remaining life of the warrant, and risk-free interest rates at each period end. There were no warrant liabilities as of December 31, 2023 or 2022.</span></div> 0 0 <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman'; font-style: italic;">Research and Development Expenses.</span><span style="font-family: 'Times New Roman';"> 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.</span></div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman'; font-style: italic;">Income Taxes.</span><span style="font-family: 'Times New Roman';"> The Company accounts for income taxes in accordance with the accounting rules that requires an asset and liability approach to accounting for income taxes based upon the future expected values of the related assets and liabilities. Deferred income tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and for tax loss and credit carry forwards and are measured using the expected tax rates estimated to be in effect when such basis differences reverse. Valuation allowances are established, if necessary, to reduce the deferred tax asset to the amount that will, more likely than not, be realized.</span></div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman'; font-style: italic;">Concentration of Credit Risk.</span><span style="font-family: 'Times New Roman';"> Financial instruments that subject the Company to credit risk consist of cash and cash equivalents. The Company maintains cash and cash equivalents and certificates of deposit with well-capitalized financial institutions. At times, those amounts may exceed federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant credit risk beyond the normal credit risk associated with commercial banking relationships. The Company has no other significant concentrations of credit risk.</span></div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-family: 'Times New Roman'; font-style: italic;">Stock-Based Compensation.</span><span style="font-family: 'Times New Roman';"> Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the service period, which generally represents the vesting period. For awards that have performance-based vesting conditions the Company recognizes the expense over the estimated period that the awards are expected to be earned. The Company generally uses the Black-Scholes option-pricing model to calculate the grant date fair value of stock options. The expense recognized over the service period is required to include an estimate of the awards that will be forfeited.</span></div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-size: 10pt; font-family: 'Times New Roman'; font-style: italic;">Recent Accounting Standards. </span>In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The new standard also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis, with early adoption permitted beginning on January 1, 2021. The Company adopted ASU 2020-06 effective January 1, 2022. The adoption of ASU 2020-06 did not have an impact on the Company’s financial statements.

or (c) thirty days after the shares of common stock of the Company have a closing price of $6.00 or greater for 10 consecutive trading days.

Finally, a beneficial ownership limitation provision was added in the Series B Warrants, which would have the effect of decreasing 10X Fund’s beneficial ownership to 9.99% and would bar the voluntary exercise of any warrants that would result in 10X Fund’s ownership beyond 9.99% without at least 61 days’ prior notice from 10X Fund.</div> <div style="margin-left: 24.5pt; font-family: 'Times New Roman'; font-size: 10pt;"> <br/> </div> <div style="margin-left: 24.5pt; font-family: 'Times New Roman'; font-size: 10pt;">The Company has accounted for the modified terms of the warrants pursuant to ASC 815, Derivatives and Hedging, whereby the Company has recognized a deemed dividend for the change in fair value of the warrants immediately before and immediately after the modification. In September 2023, the Company recognized a non cash deemed dividend of $3,619,000 related to the extension of the 5,732,253 warrants. The following assumptions were used to value the extension of the warrants immediately before and immediately after the modification: a) immediately before the modification — an expected life range of 0 to 1.63 years, volatility range of 71% to 77%%, risk free interest rate range of 5.37% and zero dividends and; b) immediately following the modification — an expected life of 3 years, volatility of 79%, risk free interest rate range of 4.59% and zero dividends.</div> <div style="margin-left: 24.5pt; font-family: 'Times New Roman';

At December 31, 2023, 3,954,727 shares were available for future grant under the 2019 Plan. Also, the Company previously had the 2009 Incentive Compensation Plan (the “2009 Plan”) which, after amendments, provided for issuance of up to 6,733,334 shares of the Company’s common stock in the form of options, stock appreciation rights, restricted stock and other stock-based awards to employees, officers, directors, consultants and other eligible persons. Provisions of the 2009 Plan stipulated that no grants could be made after February 2019; however, grants made prior to that date remain outstanding for their legal term.</div> <div style="font-family: 'Times New Roman';

font-family: 'Times New Roman'; font-size: 10pt;">As noted above, the fair value of stock options is determined by using the Black-Scholes option pricing model. For all options granted since January 1, 2006 the Company has generally used option terms of between 5 to 10 years, generally with 5 to 6 years representing the estimated life of options granted to employees. The volatility of the common stock is estimated using historical volatility over a period equal to the expected life at the date of grant. The risk-free interest rate used in the Black-Scholes option pricing model is determined by reference to historical U.S. Treasury constant maturity rates with terms equal to the expected terms of the awards. An expected dividend yield of zero is used in the option valuation model, because the Company does not expect to pay any cash dividends on common stock in the foreseeable future. At December 31, 2023, the Company does not anticipate any option awards will be forfeited in the calculation of compensation expense due to the limited number of employees that receive stock option grants and the Company’s historical employee turnover; however, any forfeitures will be accounted for as incurred.</div> <div style="font-family: 'Times New Roman'; font-size: 10pt;"><br/> </div> <div style="margin-left: 24.5pt; font-family: 'Times New Roman';

font-size: 10pt;"><br/> </div> <div style="margin-left: 24.45pt; font-family: 'Times New Roman'; font-size: 10pt;"> 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&amp;D”) contributed by SBH. The estimated fair value of the IPR&amp;D contributed by SBH, on the date of contribution, was $400,000. Initially, the Company and SBH have 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&amp;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. As a result, the Company contributed the $73,000 needed for the fourth quarter of 2014 expenses of the LLC and an additional $2,552,000 in total from 2015 through 2021. The Company contributed $561,000 and $213,000 for the LLC expenses (recorded in research and development expenses) in 2023 and 2022, and SBH has contributed a total of $711,000 since 2014. As of December 31, 2023, the Company’s ownership percentage in the LLC was 84.2%. 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. The Company’s portion of the LLC’s net loss for 2014, prior to the change in accounting discussed previously, was $400,000, which includes the Company’s proportionate share of the non-cash charge associated with the contributed IPR&amp;D of $200,000.</div> 400000 400000 0.50 400000 73000 2552000 561000 213000 711000 0.842 400000 200000 <table cellpadding="0" cellspacing="0" class="DSPFListTable" style="font-family: 'Times New Roman';
