License and Collaboration Agreements

License and Collaboration Agreements

10. License and Collaboration Agreements

Apollomics

In 2020, the Company entered into a collaboration and license agreement (the Agreement) with Apollomics (Hong Kong), Limited (Apollomics) for the development, manufacture and commercialization of products derived from two of the Company’s compounds, GMI-1271 and GMI-1687 (the Products) for therapeutic and prophylactic uses (the Field) in China, Taiwan, Hong Kong and Macau (the Territory). Under the terms of the Agreement, the Company granted Apollomics:

●

an exclusive license, with the right to sublicense, to develop, manufacture and have manufactured, distribute, market, promote, sell, have sold, offer for sale, import, label, package and otherwise the Products in the Field in the Territory; and

●

a non-exclusive license to conduct preclinical research with respect to Products in the Field outside of the Territory for the purposes of developing such Products for use in the Territory.

In 2020, the Company and Apollomics also entered into a clinical supply agreement pursuant to which the Company will manufacture and supply the Products at agreed upon prices. Apollomics has the option to begin manufacture of the Products after appropriate material transfer requirements are met. The Company did not recognize any revenue under the clinical supplies agreement during the six months ended June 30, 2024 and 2023.

The Company evaluated the Agreement under the provisions of ASC 606 and identified two performance obligations under this revenue arrangement: the (i) delivery of functional licenses and (ii) manufacture and supply of the Products. The initial transaction price consists of a $9.0 million non-refundable up-front payment which was allocated to the delivered functional licenses and recognized in full as revenue in 2020 given that the performance obligation was satisfied upon inception. The Agreement contains various forms of variable consideration, including (i) up to $75.0 million in development milestones based on achievement of certain clinical and regulatory events, (ii) up to $105.0 million of sales-based commercial milestones based on achievement of certain annual net sales targets, (iii) sales-based royalties at specified percentages of net sales ranging from the high single digits to 15%, and (iv) manufacture and supply of clinical and commercial Products. The Company has fully constrained the development milestone consideration using the most likely amount method and will recognize that revenue when it is probable that recognition of revenue related to the milestone will not result in a significant reversal in amounts recognized in future periods, and as such have been excluded from the transaction price. The Company did not recognize any milestone revenue under the Agreement for the six months ended June 30, 2024 or 2023.

The Company will recognize revenue related to the sales-based commercial and royalty milestones and royalties at the later of (i) when the related sales occur or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied), as they were determined to relate predominantly to the licenses granted to Apollomics and, therefore, have been excluded from the transaction price. Lastly, the Company has determined that the consideration for the manufacturing and supply is all variable and is fully constrained. Variable consideration allocated to manufacturing and supply will be recognized at a point in time when the Product is delivered and when the title to the Product is transferred to the customer pursuant to the agreement. The Company reassesses the transaction price in each reporting period and upon the occurrence of a change in circumstances or final resolution of any particular event.

Going Concern

2. Going Concern

The accompanying unaudited financial statements have been prepared assuming that the Company will continue as a going concern within one year after the date that the financial statements are issued. During 2023, the Company incurred a net loss of $36.9 million and had net cash flows used in operating activities of $34.9 million. The Company incurred a net loss of $20.8 million and had net cash flows used in operating activities of $19.4 million during the six months ended June 30, 2024. At June 30, 2024, the Company had $22.4 million in cash and cash equivalents and had no committed source of additional funding from either debt or equity financings, although the Company may, at its discretion, sell equity securities under the terms of its existing at-the-market sales agreement (see Note 7), subject to certain conditions and limitations. Management believes that given the Company’s current cash position and forecasted negative cash flows from operating activities over the next twelve months, despite the adoption of a streamlined operating plan, there is substantial doubt about its ability to continue as a going concern after the date that is one year from the date that these unaudited financial statements are issued, without obtaining additional financing or entering into another form of non-equity or debt arrangement. The Company expects that its current cash resources will only be sufficient to fund the Company’s operations into the second quarter of 2025.

The Company’s ability to fund its operations is dependent upon management’s plans, which include reducing operating expenses and potentially entering into collaborations, strategic alliances and marketing, distribution or licensing arrangements in order to raise additional capital. There can be no assurances that any strategic transactions will be available to the Company on commercially acceptable terms, or at all. Also, any collaborations, strategic alliances and marketing, distribution or licensing arrangements may require the Company to give up some or all of its rights to a product or technology, which in some cases may be at less than the full potential value of such rights. If the Company is unable to obtain additional capital or enter into a strategic transaction, the Company will need to eliminate some or all of its operations and may seek to liquidate.

The accompanying financial statements do not include any adjustments that might be necessary if the Company is not able to continue as a going concern.

2013 Equity Incentive Plan

The Company’s board of directors adopted, and its stockholders approved, its 2013 Equity Incentive Plan effective in January 2014, and the 2013 Equity Incentive Plan was amended and restated by approval of the board of directors in April 2022 and by approval of the stockholders in May 2022 (as so amended and restated, the 2013 Plan). The 2013 Plan provides for the grant of incentive stock options within the meaning of Section 422 of the Internal Revenue Code (the Code) to the Company’s employees and its parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, restricted stock awards, restricted stock unit awards (RSUs), stock appreciation rights, performance stock awards and other forms of stock compensation to its employees, including officers, consultants and directors. The 2013 Plan also provides for the grant of performance cash awards to the Company’s employees, consultants and directors. Unless otherwise stated in a stock option agreement, 25% of the shares subject to an option grant will typically vest upon the first anniversary of the vesting start date and thereafter at the rate of one forty-eighth of the option shares per month as of the first day of each month after the first anniversary. Upon termination of employment by reasons other than death, cause, or disability, any vested options will terminate 90 days after the termination date, unless otherwise set forth in a stock option agreement. Stock options generally terminate 10 years from the date of grant.

Authorized Shares

The maximum number of shares of common stock that may be issued under the 2013 Plan was originally 1,000,000 shares, plus any shares subject to stock options or similar awards granted under the 2003 Plan that expire or terminate without having been exercised in full or are forfeited to or repurchased by the Company. Upon the amendment and restatement of the 2013 Plan in May 2022, the existing share reserve was increased by 2,619,622. Beginning on January 1, 2023 and ending on (and including) January 1, 2029, the maximum number of shares of common stock that

may be issued under the 2013 Plan will cumulatively be increased by 4% of the number of shares of common stock issued and outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the board of directors or the compensation committee thereof. The maximum number of shares that may be issued pursuant to exercise of incentive stock options under the 2013 Plan is 20,000,000 shares. As of June 30, 2024, the total number of shares reserved for issuance under the 2013 Plan was 14,257,627 shares, of which 94,036 shares were available for future grants.

Shares issued under the 2013 Plan may be authorized but unissued or reacquired shares of common stock. Shares subject to stock awards granted under the 2013 Plan that expire or terminate without being exercised in full, or that are paid out in cash rather than in shares, will not reduce the number of shares available for issuance under the 2013 Plan. Additionally, shares issued pursuant to stock awards under the 2013 Plan that the Company repurchases or that are forfeited, as well as shares reacquired by the Company as consideration for the exercise or purchase price of a stock award or to satisfy tax withholding obligations related to a stock award, will become available for future grant under the 2013 Plan.

A summary of the Company’s stock option activity under the 2013 Plan for the six months ended June 30, 2024 is as follows:

As of June 30, 2024, there was $10,012,044 of total unrecognized compensation expense related to unvested options under the 2013 Plan that will be recognized over a weighted-average period of approximately 3.2 years. Total intrinsic value of the options exercised during the six months ended June 30, 2024 was $4,091 and total cash received for options exercised was $5,398. Total intrinsic value of the options exercised during the six months ended June 30, 2023 was $54,083 and total cash received for options exercised was $53,882. The total fair value of stock options which vested in the six months ended June 30, 2024 and 2023 was $2,182,608 and $1,090,699, respectively.

The Company has granted stock options to purchase an aggregate of 2,509,275 shares to certain employees under the 2013 Plan, the vesting of which is subject to performance vesting conditions relating to the achievement of specified regulatory or commercial milestones. The maximum fair value of $681,766 associated with performance-based options granted has been excluded from the unrecognized compensation expense under the 2013 Plan as the completion of the performance milestones was not deemed to be probable as of June 30, 2024.

An RSU is a stock award that entitles the holder to receive shares of the Company’s common stock as the award vests. The fair value of each RSU is based on the closing price of the Company’s common stock on the date of grant. In January 2021, the Company awarded RSUs under the 2013 Plan to all of its employees. The RSUs granted vest over four years in equal installments on each anniversary of the grant date, provided that the employee remains employed by the Company at the applicable vesting date. Compensation expense is recognized on a straight-line basis. As of June 30, 2024, there was $103,762 of total unrecognized compensation expense associated with outstanding RSU grants that will be recognized over a weighted-average period of approximately 0.6 years.

The following is a summary of RSU activity under the 2013 Plan for the six months ended June 30, 2024:


		Weighted-Average
	Number of Shares	Grant Date
	Underlying RSUs	Fair Value
Unvested at December 31, 2023	117,157	$	3.81
Vested	(58,581)		3.81
Forfeited	(9,581)		3.81
Unvested at June 30, 2024	48,995		3.81

Issuance of Shares to Directors in Lieu of Cash Retainers for Service

In March 2023, the Company’s board of directors amended the Company’s Non-Employee Director Compensation Policy to include an election to receive unrestricted shares of common stock in lieu of quarterly board and committee retainer cash payments. The number of shares to be issued to an electing director is determined on the last day of each fiscal quarter by dividing the dollar amount of the compensation to be paid for such quarter that is subject to the election by the closing price of a share of common stock on the last trading day of the fiscal quarter, rounded up to the nearest whole share. Non-employee directors who made such an election received 13,127 shares of common stock in lieu of cash compensation earned for the quarter ended March 31, 2024. All shares of common stock issued pursuant to such an election are fully vested upon issuance and are classified as “Other Awards” under the 2013 Plan.

In June 2024, the Non-Employee Director Compensation Policy was amended to allow a director to revoke his or her annual election to receive unrestricted shares of common stock in lieu of quarterly board and committee retainer cash payments. The decision to amend the policy followed a significant decline in the market value of the Company’s common stock in May 2024. Without the ability of the directors to revoke the prior elections, the Company would have been obligated to issue a significantly greater number of shares than in prior quarters in lieu of the fixed cash retainer payments. Each of the directors who previously elected to receive unrestricted shares of common stock in lieu of quarterly board and committee retainer cash payments for 2024 revoked their elections in June 2024, and as a result there were no additional shares issued under the policy for the three months ended June 30, 2024.

Inducement Plan

The Company’s board of directors previously adopted the GlycoMimetics, Inc. Inducement Plan (as amended to date, the Inducement Plan). The Inducement Plan provides for the grant of nonstatutory stock options, restricted stock awards, RSU awards, stock appreciation rights and other forms of stock awards to individuals not previously an employee or director of the Company as an inducement for such individuals to join the Company. Unless otherwise stated in an applicable stock option agreement, one-fourth of the shares subject to an option grant under the Inducement Plan will typically vest upon the first anniversary of the vesting start date, with the balance of the shares vesting in a series of thirty-six successive equal monthly installments as of the first day of each month measured from the first anniversary of the vesting start date, subject to the new employee’s continued service with the Company through the applicable vesting dates. Upon termination of employment by reasons other than death, cause or disability, any vested options will terminate 90 days after the termination date, unless otherwise set forth in a stock option agreement. Stock options generally terminate 10 years from the date of grant. The Inducement Plan was amended by the board of directors on multiple occasions to increase the number of shares reserved for issuance to 3,000,000 shares as of June 30, 2024. As of June 30, 2024, there were 271,358 shares available for future grants under the Inducement Plan.

A summary of the Company’s stock option activity under the Inducement Plan for the six months ended June 30, 2024 is as follows:

As of June 30, 2024, there was $1,419,532 of total unrecognized compensation expense related to unvested options under the Inducement Plan that will be recognized over a weighted-average period of approximately 2.3 years. There were no options exercised under the Inducement Plan during the six months ended June 30, 2024 or 2023. The total fair value of stock options which vested in the six months ended June 30, 2024 and 2023 was $474,192 and $312,314, respectively.

The Company has granted stock options to purchase an aggregate of 584,200 shares to certain newly hired employees under the Inducement Plan which options are subject to performance-based conditions. The maximum fair value of $825,353 associated with the performance-based options is excluded from the unrecognized compensation expense under the Inducement Plan as the completion of the performance milestones was not probable as of June 30, 2024.

The weighted-average fair value of the options granted under all equity incentive plans during the six months ended June 30, 2024 and 2023 was $1.49 per share and $2.00 per share, respectively, applying the Black-Scholes-Merton option pricing model utilizing the following weighted-average assumptions:

In July 2024, the Company’s Board of Directors approved a streamlined operating plan that includes the exploration of strategic alternatives focused on maximizing shareholder value. The Company concluded, following feedback from the U.S. Food and Drug Administration, that the regulatory path forward for its lead product candidate uproleselan for the treatment of relapsed and refractory acute myeloid leukemia would require an additional clinical trial. The decision was not related to any safety or medical issues or negative regulatory feedback related to the Company’s programs.

In connection with the streamlined operating plan approved by the Board, the Company has undertaken a corporate restructuring that includes a reduction in the Company’s workforce by 26 employees, or approximately 80% of its headcount. The Company anticipates recognizing approximately $3.6 million in total charges in connection with the headcount reduction, which costs are expected to be substantially recognized in the third quarter of 2024, with related cash payments expected to be paid out by the end of 2024. These charges will consist primarily of one-time severance payments upon termination and continued benefits for a specified period of time.

6. Operating Leases

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the circumstances present. The Company determines a lease exists if the contract conveys the right to control an identified asset for a period of time in exchange for consideration. Control is considered to exist when the lessee has the right to obtain substantially all of the economic benefits from the use of an identified asset as well as direct the right to use of that asset. Leases with a term greater than one year are recognized on the balance sheet as right-of-use assets, lease liabilities and, if applicable, long-term lease liabilities. The Company has elected not to recognize on the balance sheet leases with terms of one year or less on the lease commencement date. If a contract is considered to be a lease, the Company recognizes a lease liability based on the present value of the future lease payments over the expected lease term, with an offsetting entry to recognize a right-of-use asset. The Company has also elected to use the practical expedient and account for each lease component and related non-lease component as one single component. The lease component results in a right-of-use asset being recorded on the balance sheet and amortized as lease expense on a straight-line basis.

The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a term similar to the term of the lease for which the rate is estimated. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received.

The Company leases office and research space in Rockville, Maryland under an operating lease that is subject to annual rent increases (the Lease). The Company paid a security deposit of $52,320 to be held until the expiration or termination of the Company’s obligations under the Lease. In April 2023, the Company and its landlord entered into an amendment to the Lease (the Lease Amendment). Pursuant to the Lease Amendment, the Company and the landlord agreed that the lease term for a portion of the premises, consisting of approximately 30,000 square feet, would be extended from November 1, 2023 to January 31, 2025. The Company’s lease of the remaining premises, consisting of approximately 12,000 square feet, expired on October 31, 2023. There were no additional operating leases entered into during the six months ended June 30, 2024.

The components of lease expense and related cash flows were as follows:

Significant Accounting Policies

Significant Accounting Policies

3. Significant Accounting Policies

There have been no material changes to the significant accounting policies previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the United States Securities and Exchange Commission (the SEC) on March 27, 2024 (the Form 10-K).

Basis of Accounting

The accompanying unaudited financial statements were prepared based on the accrual method of accounting in accordance with U.S. generally accepted accounting principles (GAAP).

Unaudited Financial Statements

The accompanying balance sheet as of June 30, 2024, statements of operations and comprehensive loss and stockholders’ equity for the three and six months ended June 30, 2024 and 2023 and statements of cash flows for the six months ended June 30, 2024 and 2023 are unaudited. These unaudited financial statements have been prepared in accordance with the rules and regulations of the SEC for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete annual financial statements. These unaudited financial statements should be read in conjunction with the audited financial statements and the accompanying notes for the year ended December 31, 2023 contained in the Form 10-K. The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and in the opinion of management reflect all adjustments (consisting of normal recurring adjustments) necessary to state fairly the Company’s financial position as of June 30, 2024 and its results of operations and changes in its stockholders’ equity for the three and six months ended June 30, 2024 and 2023 and its cash flows for the six months ended June 30, 2024 and 2023. The December 31, 2023 balance sheet included herein was derived from audited financial statements, but does not include all disclosures including notes required by GAAP for complete annual financial statements. The financial data and other information disclosed in these notes to the financial statements related to the three and six months ended June 30, 2024 and 2023 are unaudited. Interim results are not necessarily indicative of results for an entire year or for any future period.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Although actual results could differ from those estimates, management does not believe that such differences would be material.

Fair Value Measurements

The Company had no assets or liabilities that were measured using quoted prices for similar assets and liabilities or significant unobservable inputs (Level 2 and Level 3 assets and liabilities, respectively) as of June 30, 2024 and December 31, 2023. The carrying value of cash held in money market funds of $18.8 million and $38.8 million as of June 30, 2024 and December 31, 2023, respectively, is included in cash and cash equivalents and approximates market values based on quoted market prices (Level 1 inputs). The Company did not transfer any assets measured at fair value on a recurring basis between levels during the three and six months ended June 30, 2024 and 2023.

Concentration of Credit Risk

Credit risk represents the risk that the Company would incur a loss if counterparties failed to perform pursuant to the terms of their agreements. Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains its cash balances with financial institutions in federally insured accounts and has cash balances in excess of the insurance limits. Cash equivalents consist of investment in United States government money market funds with major financial institutions. These deposits and funds may be redeemed upon demand and the Company does not anticipate any losses on such balances. The Company has not experienced any losses to date and believes that it is not exposed to any significant credit risk on cash and cash equivalents.

Revenue Recognition

The Company applies Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers (Topic 606), to all contracts with customers, except for contracts that are within the scope of other standards,

such as leases, insurance, collaboration arrangements and financial instruments. Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods and services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with the customer(s); (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods and services it transfers to the customer. At contract inception, the Company assesses the goods or services promised within each contract that falls under the scope of Topic 606, determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

The Company enters into licensing agreements which are within the scope of Topic 606, under which it licenses certain of its drug candidates’ rights to third parties. The terms of these arrangements typically include payment of one or more of the following: non-refundable, up-front license fees; development, regulatory and commercial milestone payments; and royalties on net sales of the licensed product, if and when earned. See Note 10 for additional information regarding the Company’s license agreements.

In determining the appropriate amount of revenue to be recognized as it fulfills its obligation under each of its agreements, the Company performs the five steps under Topic 606 described above. As part of the accounting for these arrangements, the Company must develop assumptions that require judgment to determine the stand-alone selling price, which may include forecasted revenues, development timelines, reimbursement of personnel costs, discount rates and probabilities of technical and regulatory success.

Licensing of Intellectual Property: If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from non-refundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company evaluates the measure of progress each reporting period, and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone Payments: At the inception of each arrangement that includes development milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal will not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such development milestones and any related constraint and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect license, collaboration and other revenues and earnings in their period of adjustment.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and for which the license is deemed to be the predominant item to which royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any royalty revenue from its license agreements.

Manufacturing and Supply: The obligations under the Company’s agreements may include clinical and/or commercial manufacturing products to be provided by the Company to the counterparty. The services are generally determined to be distinct from the other promises or performance obligations identified in the arrangement. The

Company recognizes the transaction price allocated to these services as revenue at a point in time when transfer of control of the related products to the customer occurs.

Accruals for Clinical Trial Expenses

Clinical trial costs primarily consist of expenses incurred under agreements with contract research organizations (CROs), investigative sites, laboratory testing expenses, data management and consultants that conduct the Company's clinical trials. Clinical trial expenses have historically been a significant component of research and development expenses, and the Company previously outsourced a significant portion of its clinical trial activities to third parties. The accrual for site and patient costs includes inputs such as estimates of patient enrollment, patient cycles incurred, estimated project duration and other pass-through costs. As a result of the Company ceasing its clinical activities, the costs of closing down clinical sites are also included in the accruals. These inputs are required to be estimated due to a lag in receiving the actual clinical information from third parties. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected on the balance sheets as a prepaid asset or accrued expenses. These third-party agreements are generally cancellable, and related costs are recorded as research and development expenses as incurred. Except for payments made in advance of services, clinical trial costs are expensed as incurred. Non-refundable advance clinical payments for goods or services that will be used or rendered for future research and development activities are recorded as a prepaid asset and recognized as expense as the related goods are delivered or the related services are performed. When evaluating the adequacy of the accrued expenses, management assessments include: (i) an evaluation by the project manager of the work that has been completed during the period; (ii) measurement of progress prepared internally and/or provided by the third-party service provider; (iii) analyses of data that justify the progress; and (iv) the Company’s judgment. Significant judgments and estimates may be made in determining the accrued balances at the end of any reporting period. Actual results could differ from the estimates made. The Company’s historical clinical accrual estimates have not been materially different from the actual costs.

Stock-Based Compensation

Stock-based payments are accounted for in accordance with the provisions of ASC 718, Compensation—Stock Compensation. The fair value of stock-based payments is estimated, on the date of grant, using the Black-Scholes-Merton model. The resulting fair value is recognized ratably over the requisite service period, which is generally the vesting period of the option. The Company accounts for forfeitures as they occur.

The Company has elected to use the Black-Scholes-Merton option pricing model to value any options granted. The Company will reconsider use of the Black-Scholes-Merton model if additional information becomes available in the future that indicates another model would be more appropriate or if grants issued in future periods have characteristics that prevent their value from being reasonably estimated using this model.

A discussion of management’s methodology for developing some of the assumptions used in the valuation model follows:

Expected Dividend Yield—The Company has never declared or paid dividends and has no plans to do so in the foreseeable future.

Expected Volatility—Volatility is a measure of the amount by which a financial variable such as share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company bases the expected volatility on the historical volatility of the Company’s publicly traded common stock.

Risk-Free Interest Rate—This is the U.S. Treasury rate for the week of each option grant during the year, having a term that most closely resembles the expected life of the option.

Expected Term—This is a period of time that the options granted are expected to remain unexercised. Options granted have a maximum term of 10 years. The Company estimates the expected life of the option term to be 6.25 years. The Company uses a simplified method to calculate the average expected term.

Net Loss Per Common Share

Basic net loss per common share is determined by dividing net loss by the weighted-average number of common shares outstanding during the period, without consideration of common stock equivalents. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common stock equivalents outstanding for the period. The treasury stock method is used to determine the dilutive effect of the Company’s stock options and restricted stock units (RSUs).

The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted-average common shares outstanding, as they would be anti-dilutive:


	Six Months Ended June 30,
	2024	2023
Stock options and RSUs	16,047,875	11,469,764

Comprehensive Loss

Comprehensive loss comprises net loss and other changes in equity that are excluded from net loss. For the three and six months ended June 30, 2024 and 2023, the Company’s net loss equaled comprehensive net loss and, accordingly, no additional disclosure is presented.

1. Description of the Business

GlycoMimetics, Inc. (the Company), a Delaware corporation headquartered in Rockville, Maryland, was incorporated in 2003. The Company is focused on improving the lives of people living with cancer and inflammatory diseases by leveraging the inhibition of carbohydrate interactions that occur on the surface of cells. The Company has been developing a pipeline of proprietary glycomimetics, which are small molecules that mimic the structure of carbohydrates involved in important biological processes, to inhibit disease-related functions of carbohydrates such as the roles they play in cancers and inflammation. In July 2024, following feedback from the U.S. Food and Drug Administration (FDA), the Company determined that the regulatory path forward for its lead product candidate, uproleselan, for the treatment of relapsed and refractory acute myeloid leukemia would require an additional clinical trial. As a result, the Company intends to conduct a strategic review of its business, in an effort to maximize shareholder value, including the evaluation of potential business development opportunities for uproleselan and the Company’s GMI-1687 to ensure their continued advancement. In order to conserve its cash resources, in July 2024 the Company reduced its workforce by approximately 80%.
