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> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">The unaudited condensed consolidated financial statements as reported in this Quarterly Report on Form <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">10-Q</div> reflect all adjustments which are, in the opinion of management, necessary to present fairly the financial position of the Company as of June 30, 2020 and the results of its operations for the three and six months ended June 30, 2020 and 2019 and its cash flows for the six months ended June 30, 2020 and 2019. 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, 2019 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 <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">10-K</div> for the year ended December 31, 2019.</div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">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 June 30, 2020, the Company had $40,768,000 of unrestricted cash and cash equivalents available to fund future operations. The Company believes there is sufficient cash, including availability of the $10 million line of credit (see Note 3), to fund currently planned operations at least through September 30, 2021. We will require more cash to fund our operations after September 30, 2021 and believe we will be able to obtain additional financing. The currently planned operations include costs related to a planned adaptively designed <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">NASH-RX</div> Phase 2b/3 clinical trial. The costs of the trial along with drug manufacturing and other scientific support activities and general overhead during the first stage of the trial are currently estimated to be approximately $90 million. These costs will require additional funding. 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, 2021, 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.</div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">The Company was founded in July 2000, was incorporated in the State of Nevada in January 2001 under the name <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">“Pro-Pharmaceuticals,</div> Inc.,” and changed its name to “Galectin Therapeutics Inc.” on May 26, 2011.</div> 40768000 90000000 <div style="font-family: 'Times New Roman'; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: 'Times New Roman'; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">2.

Uihlein, a director and shareholder. Originally, borrowings may be made by the Company through December 31, 2018. Borrowings bear interest at the Applicable Federal Rate for short term loans published by the Internal Revenue Service (1.6% in December 2019). All borrowings and interest were originally due on December 31, 2019 but may be prepaid without penalty. 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. There have been no borrowings under the Line of Credit to date. </div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: 'Times New Roman'; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On December 20, 2018, the Line of Credit arrangement was extended for one year for both borrowings and maturity. At the time of the conversion of the Series B Convertible Preferred stock into common stock (See Note 9), on January 11, 2019, the Line of Credit arrangement was extended for an additional two years for both borrowings and maturity. After the second amendment to the Line of Credit arrangement, borrowings may be made through December 31, 2021 with repayment due on December 31, 2022. There was no additional consideration or benefits provided to Mr. Uihlein for any of the extensions of the Line of Credit. </div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">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 <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">(non-current)</div> 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 six months ended June 30, 2020 and 2019 of $43,000 and $43,000, 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.</div> 10000000 0.016 1000000 5 0 500000 696000 P7Y 0.98 0.0205 0 43000 43000 <div style="font-family: 'Times New Roman'; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: 'Times New Roman'; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">4.

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 June 30, 2020 or December 31, 2019. </div></div> <div style="font-family: 'Times New Roman'; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: 'Times New Roman'; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">7.

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:</div> <table cellpadding="0" cellspacing="0" style="margin: 0px auto;

Pursuant to the terms of the conversion, as of January 11, 2019, 10X Fund converted 5,508,000 shares of its Series <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">B-1,</div> <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">B-2</div> and <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">B-3</div> Convertible Preferred Stock into 3,789,346 shares of Common Stock of Galectin Therapeutics. All special voting rights and protective provisions that previously benefited the Series B Preferred Stock were extinguished by the conversion to Common Stock.</div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In connection with the conversion of the Series B Preferred Stock, the Company extended by five years the exercise date of warrants for 3,579,642 shares of Common Stock issued by the Company in connection with sale of the Series <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">B-1</div> and Series <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">B-2</div> Preferred Stock. Before the extension, the warrants had various expiration dates in 2019 and 2020. The warrant amendments give 10X Fund the right to nominate one director to the Company’s board of directors. Previously, under the now extinguished voting rights of the Series B Preferred, 10X Fund had the right to name two directors and nominate an additional three directors.</div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">The Company has accounted for the modified terms of the warrants pursuant to ASC 718, Stock Compensation, whereby the Company has recognized a charge for the change in fair value of the warrants immediately before and immediately after the modification. In January 2019, the Company recognized a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">one-time</div> <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-cash</div> charge of $6,622,000 related to the extension of the 3,579,642 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 0.09 to 1.33 years, volatility of 98%, risk free interest rate range of 2.4% to 2.59% and zero dividends and; b) immediately following the modification — an expected life range of 5.09 to 6.33 years, volatility range of 106%, risk free interest rate range of 2.56% to 2.6% and zero dividends.</div> 5508000 3789346 3579642 6622000 3579642 0.09 1.33 98 2.4 2.59 0 5.09 6.33 106 2.56 2.6 <div style="font-family: 'Times New Roman'; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: 'Times New Roman'; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">10.

Leases </div></div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">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.

Galectin Sciences LLC </div></div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">In January 2014, we created Galectin Sciences, LLC (the “LLC” or “Investee”), a collaborative joint venture <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">co-owned</div> by SBH Sciences, Inc. (“SBH”), to research and develop small organic molecule inhibitors of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">galectin-3</div> 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 <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">in-process</div> 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 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&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. Since then, the Company has contributed a total of $2,260,000, including $309,000 for the six months ended June 30, 2020, for expenses of the LLC. Since the end of 2014, SBH has contributed $158,000 for expenses in the LLC. As of June 30, 2020, the Company’s ownership percentage in the LLC was 82.6%. 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 <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-controlling</div> interest is also deemed to be immaterial.</div> 400000 400000 0.50 400000 2260000 309000 158000 0.826
