Galectin Therapeutics Inc. (the “Company”) is a development-stage 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, 2014 and the results of its operations for the three months ended March 31, 2014 and 2013 and the cumulative period from inception (July 10, 2000) through March 31, 2014 and its cash flows for the three months ended March 31, 2014 and 2013, and for the cumulative period from inception (July 10, 2000) to March 31, 2014. All adjustments made to the interim financial statements include all those of a normal and recurring nature. 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 which 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, 2013. The Company has operated at a loss since its inception and has had no significant revenues. The Company anticipates that losses will continue for the foreseeable future. At March 31, 2014, the Company had $36.6 million of unrestricted cash and cash equivalents available to fund future operations. The Company believes that with the cash on hand at March 31, 2014, there is sufficient cash to fund operations through 2015. The Company’s ability to fund operations after its current cash resources are exhausted depends on its ability to obtain additional financing or achieve profitable operations, as to which no assurances can be given. Accordingly, based on the forecasts and estimates underlying the Company’s current operating plan, the financial statements do not currently include any adjustments that might be necessary if the Company is unable to continue as a going concern. As shown in the condensed consolidated financial statements, the Company incurred cumulative net losses applicable to common stockholders of $107.6 million for the cumulative period from inception (July 10, 2000) through March 31, 2014. The Company’s net losses have resulted principally from costs associated with (i) research and development expenses, including clinical trial costs, (ii) general and administrative activities and (iii) the Company’s financing transactions including interest, dividend payments, and the costs related to fair value accounting for the Company’s convertible debt instruments. As a result of planned expenditures for future research, discovery, development and commercialization activities and potential legal cost to protect its intellectual property, the Company expects to incur additional losses and use additional cash in its operations for the foreseeable future. Through March 31, 2014, the Company had raised a net total of $107.5 million in capital through sale and issuance of common stock, common stock purchase warrants, convertible preferred stock and debt securities in public and private offerings. From inception (July 10, 2000) through March 31, 2014, the Company used cash of $69.7 million in its operations. 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. On March 23, 2012, the Company began trading on The NASDAQ Capital Market under the symbol GALT. Immediately prior to March 23, 2012, the Company was traded on the Over-the Counter Bulletin Board (“OTCBB”) under the symbol GALT.OB. The Company is subject to a number of risks similar to those of other development-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. |

Following is the stock-based compensation expense related to common stock options, common stock, restricted common stock and common stock warrants:
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, 2013 through March 31, 2014:
As of March 31, 2014, there was $6,491,000 of unrecognized compensation related to 1,360,476 unvested options, which is expected to be recognized over a weighted–average period of approximately 2.6 years. The weighted-average grant date fair value for options granted during the three months ended March 31, 2014 and 2013 was $11.28 and $2.73, respectively. The Company granted 326,500 stock options during the three months ended March 31, 2014, of which 81,625 options vested upon grant with the remaining 244,875 options vesting over 3 years. Approximately $921,000 of non-cash, stock-based compensation expense was recorded during the three months ended March 31, 2014 related to the options granted during the quarter that were vested upon the grant date. The fair value of all other options granted is determined using the Black-Scholes option-pricing model. The following weighted average assumptions were used:
In January 2014, the Company entered into an agreement with a consultant that provided for the grant of 3,000 shares of common stock. The Company recognized an expense of $25,000, representing the market value of the common stock, during the three months ended March 31, 2014. |

The following assumptions were used to value the warrants: an expected life of 3 years, volatility of 87%, risk free interest rate of 0.42% and zero dividends. The Company recognized an expense of $7,000 related to these warrants during the three months ended March 31, 2013. |

| 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 approximates their carrying value due to their short-term nature.

| 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:

| Common Stock |
March 2012 Offering and Reverse Stock Split On March 22, 2012, the Company entered into an underwriting agreement, relating to the offer and sale of 1,159,445 units (the “Units”) of the Company, each unit consisted of two shares of Common Stock and one warrant to purchase one share of Common Stock. Pursuant to the underwriting agreement, the Company granted the underwriters a 45-day option to purchase up to an additional 173,916 Units to cover over-allotments, which they exercised on March 26, 2012. The public offering price for each Unit was $9.00. Each warrant has an initial exercise price of $5.63 per share, is exercisable upon separation of the Units and expires on March 28, 2017. On March 28, 2012, the Company sold and issued 1,333,361 Units (2,666,722 shares of common stock and related $5.63 warrants to purchase 1,333,361 shares of common stock) for gross proceeds of $12.0 million (net cash proceeds of $10,403,000 after the underwriting discount and offering costs). The warrants were valued at $4,445,000 as of the issuance date of March 28, 2012, using the closing price of $4.20, a life of 5 years, a volatility of 119% and a risk free interest rate of 1.05%. Based upon the Company’s analysis of the criteria contained in ASC Topic 815-40, “Derivatives and Hedging—Contracts in Entity’s Own Equity” the Company has determined that warrants issued in connection with this financing transaction were not derivative liabilities and therefore, were recorded as additional paid-in capital. On March 28, 2012, in connection with this underwritten financing as per the underwriting agreement, the Company issued a total of 46,378 common stock purchase warrants to the underwriters. These warrants expire May 2, 2016, have an exercise price of $5.63 per share, and are exercisable beginning 1 year from March 22, 2012 (the date of the underwriting agreement). These warrants were valued at $143,000 as of the date of issuance (March 28, 2012), using the closing price of $4.20, life of 4.1 years, volatility of 117% and risk free interest rate of 0.78. Based upon the Company’s analysis of the criteria contained in ASC Topic 815-40, “Derivatives and Hedging—Contracts in Entity’s Own Equity”, the Company has determined that these warrants issued in connection with this financing transaction were not derivative liabilities and therefore, were recorded as additional paid-in capital. Effective as of March 23, 2012, and in connection with the pricing of the offering of Units, the Company effected a one-for-six reverse split of its Common Stock. Per the terms of the reverse split, all fractional shares were rounded up. At Market Issuance of Common Stock On October 25, 2013, the Company entered into an At Market Issuance Sales Agreement (the “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 $30.0 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 At Market Agreement. As of December 31, 2013, the Company had issued 99,942 shares of its common stock through its At Market issuance program at an average price of $9.02 per share resulting in gross proceeds of approximately $944,000. The Company incurred one time, initial legal and accounting costs of approximately $82,000 and commissions of $29,000 resulting in net proceeds of $833,000 as of December 31, 2013. In January and February 2014, the Company issued 2,663,647 shares of common stock for net proceeds of approximately $28,178,000 which completed the At Market Agreement. |

Separation Agreement In February 2009, the Company entered into a Separation Agreement in connection with the resignation of David Platt, Ph.D., the Company’s former Chief Executive Officer and Chairman of the Board of Directors. The Separation Agreement provides for the deferral of a $1.0 million separation payment due to Dr. Platt upon the earlier occurrence of any of the following milestone events: (i) the approval by the Food and Drug Administration for a new drug application (“NDA”) for any drug candidate or drug delivery candidate based on the Company’s GM-CT-01 technology (whether or not such technology is patented), in which case Dr. Platt is also entitled to a fully vested 10-year cashless-exercise stock option to purchase at least 83,334 shares of common stock at an exercise price not less than the fair market value of the common stock determined as of the date of grant; (ii) consummation of a transaction with a pharmaceutical company expected to result in at least $10.0 million of equity investment or $50 million of royalty revenue to the Company, in which case Dr. Platt is also entitled to stock options on the same terms to purchase at least 50,000 shares of common stock; or (iii) the renewed listing of the Company’s securities on a national securities exchange and the achievement of a market capitalization of $100 million. Payment upon the events (i) and (iii) may be deferred up to six months, and if the Company has insufficient cash at the time of any of such events, it may issue Dr. Platt a secured promissory note for such amount. If the Company files a voluntary or involuntary petition for bankruptcy, whether or not a milestone event has occurred, such event shall trigger the obligation to pay the $1.0 million with the result that Dr. Platt may assert a claim for such obligation against the bankruptcy estate. During 2011, when it became probable that the Company could be relisted on a national securities exchange and eventually reach a market capitalization of $100 million, the Company recognized the $1.0 million severance payment due to Dr. Platt and it is included in accrued expenses at December 31, 2013 and 2012. On May 2, 2012, Dr. Platt instituted an arbitration with the American Arbitration Association seeking the $1 million payment based on a claim that the milestone event in the Separation Agreement described in clause (iii) above had occurred. Although the Company had listed its common stock on the Nasdaq Capital Markets as of March 22, 2012, the market capitalization since the listing had not reached $100 million when the arbitration was heard in October 2012. On November 1, 2012, the arbitrator denied Dr. Platt’s demand in all respects. On October 12, 2012, Dr. Platt commenced a lawsuit under the Massachusetts Wage Act against Dr. Traber and Mr. McGauley who in their capacities as the Company’s Chief Executive Officer and the Company’s former Chief Financial Officer, respectively, can be held individually liable under the Wage Act for non-payment of wages. The lawsuit is based on the facts and issues raised in the arbitration regarding the payment of the $1.0 million separation payment under the Separation Agreement, and other unspecified “wages”. The statute provides that a successful claimant may be entitled to multiple damages, interest and attorney’s fees. Although the Company is not a party to the lawsuit, it plans to indemnify Dr. Traber and Mr. McGauley consistent with its obligations under the by-laws and applicable law, and intends a vigorous defense on their behalf. On April 29, 2013, the Superior Court allowed Dr. Traber’s and Mr. McGauley’s motion to dismiss. On May 28, 2013, Dr. Platt filed a Notice of Appeal to appeal the Superior Court’s order allowing the defendants’ motion to dismiss. On April 14, 2014, the Appeals Court denied Dr. Platt’s appeal of the dismissal in full. On March 29, 2013, the Company instituted arbitration before the American Arbitration Association, seeking to rescind or reform the Separation Agreement discussed above. The Company claims that Dr. Platt fraudulently induced the Company to enter into the Separation Agreement, breached his fiduciary duty to the Company, and was unduly enriched from his conduct. Along with removal of the $1.0 million milestone payment under the Separation Agreement, the Company is seeking repayment of all separation benefits paid to Dr. Platt to date. Depending on the outcome of the arbitration, the previously accrued $1.0 million could be reversed. This arbitration has been scheduled for April 28, 2014; however, the ultimate outcome is uncertain and there is no guarantee that the Company will be successful in this demand. On August 1, 2013, the market capitalization of the Company’s common stock exceeded $100 million and the Company received a letter dated October 1, 2013, demanding payment of the $1 million. As described in the preceding paragraph, the Company had previously instituted an arbitration proceeding against Dr. Platt seeking to rescind the Separation Agreement, including the milestone payment provision, and the Company is currently delaying payment pending the outcome of this arbitration. 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, except as noted above. There are no other pending legal proceedings except as noted above. |

| 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. Both the Company and SBH have a 50% equity ownership interest in the LLC, with neither party having control over the LLC. Accordingly, the Company has 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 wells 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 Company’s portion of the LLC’s net loss for the 3 month period ending March 31, 2014 was $270,000, which includes the Company’s proportionate share of the non-cash charge associated with the contributed IPR&D of $200,000. |

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
