Item 1A. Risk Factors.

In addition to other information contained in this Annual Report on Form 10-K, the following risks should be considered in evaluating our business and future prospects and an investment in our common stock. The risks and uncertainties described below are not the only ones we face. If any of the following risks and uncertainties develops into actual events, our business, financial condition, results of operations and cash flows could be materially adversely affected. In that case, the price of our common stock could decline and you may lose all or part of your investment.

Risks Related to Our Business

Our exploration of strategic alternatives may not be successful.

Given the Company’s current focus to explore growth through strategic transactions with potential partners, the Company’s ability to execute its current business plan depends on its ability to obtain additional funding via a strategic transaction or a series of strategic transactions, or to obtain funding to support such a transaction. We currently have no source of revenues or committed financing, and our financial resources are limited to our cash and cash equivalents. With respect to our efforts to maximize value from historical assets, while those efforts are continuing, based on the interest we have received to date we do not think it is likely they will generate significant value, at least in the near term.

The Company plans to continue actively pursuing strategic alternatives, however, there can be no assurance that the Company will have sufficient resources or obtain additional financing necessary to complete this effort. Even if we do have such resources or can obtain financing, we may not be able to consummate such a transaction in a timely manner or at all or in a manner that would not adversely impact our business. The accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty. Strategic transactions are complex and time-consuming to identify, evaluate, negotiate and consummate in compliance with applicable laws and Nasdaq requirements. Our board and management do not have meaningful experience executing this type of endeavor in the U.S. public markets. Even if we are successful in entering into a strategic transaction, the terms and conditions of that transaction may restrict us from entering into future agreements with other potential collaborators. Additionally, such strategic transactions may not be favorable to investors nor deliver any anticipated benefits by the time of business integration.

We need to obtain substantial funding in the near term in order to continue operations and our exploration of strategic alternatives.

We require significant capital resources in order to continue to operate our business and conduct our exploration of strategic alternatives, and our limited liquidity could materially and adversely affect our business operations. Because we have no current source of revenue or committed financing, our current available cash and cash equivalents provide us with limited liquidity. We believe that our existing cash and cash equivalents could allow us to fund our business operations into early in the fourth quarter of 2023; however, it is very difficult to project our current monthly cash burn rate given the transitional status of the Company and this estimate may prove inaccurate and we may expend our limited resources sooner. Any such required additional capital may not be available on reasonable terms, if at all, due to a variety of factors, including uncertainty about the future direction of the Company and investor reaction to our new controlling stockholder and board composition, as well as broader conditions in the economy and capital markets, including recent volatility caused by inflation, questions about bank stability and other factors. The Company has already engaged in significant cost reductions, so our ability to further cut costs and extend our operating runway is limited. Without sufficient additional capital funding in the near term, we may be required, among other things, to seek bankruptcy protection.

Our status as a “controlled company” could make our Common Stock less attractive to some investors or otherwise harm the trading price of our Common Stock.

More than 50% of our voting power is held by CBI USA. As a result, we are a “controlled company” under the corporate governance rules for Nasdaq-listed companies and may elect not to comply with certain Nasdaq corporate

14

Table of Contents

governance requirements with respect to board independence and compensation and nominating committee functions. We are relying on these exceptions. Following the closing of the Private Placement, our board includes 6 members, 5 of whom are affiliated or associated with CBI USA or were otherwise delegated by CBI USA. Investors may be hesitant to invest in the Company absent compliance with these governance requirements. In addition, should the interest or interests of our controlling stockholder differ from those of other stockholders, the other stockholders may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance rules for Nasdaq-listed companies. Our status as a controlled company could make our Common Stock less attractive to some investors, including but not limited to potential strategic partners, or otherwise harm our stock price.

Additionally, it is possible we could pursue strategic or financing transactions with our controlling stockholder or its affiliates. The interests of the controlling stockholder and other stockholders would diverge in this case, and the lack of an independent board to evaluate such a transaction could adversely impact other stockholders. These conflicts of interest (or the perception that they could occur) might adversely affect our business and prospects for obtaining financing or completing a strategic transaction.

For so long as CBI USA owns a majority of our Common Stock, it will have sufficient votes to elect all of our directors and to approve any other corporate action requiring the affirmative vote of holders of a majority of the outstanding shares of our Common Stock. Our control by a single stockholder, and our reliance on the Nasdaq controlled company exemptions, could deter investment in the Company and adversely impact our stock price and ability to obtain financing. These impacts may be more pronounced in the near term as investors assess the direction of the Company under the control of CBI USA and the actions of the new board. Potential partners considering engaging in a strategic transaction with the Company could have similar concerns. Given our urgent need for additional funding and/or to complete a strategic transaction, it is imperative that our controlling stockholder and our board earn the confidence of investors and potential partners in the near term and there is no assurance this will occur

Our controlling stockholder, and new members of our board, have limited experience controlling or governing a public company operating in the United States.

Our controlling stockholder has not previously controlled a U.S. public company. In addition, the majority of our board is made of up Korean citizens, and none of the new members of the board have experience serving as directors or management of a U.S. publicly traded company. This could make it difficult to ensure that the Company complies with all applicable laws and stock exchange requirements, maintains adequate internal and disclosure controls and appropriately assesses and manages risk. This concern is exacerbated by the limited resources the Company has following recent reductions in force, and if there are further reductions in force or members of management leave the Company, it may be very difficult to manage this risk. The transitional state of the Company and ongoing exploration of strategic alternatives also exacerbates the challenging environment in this respect. If the board of directors does not successfully or efficiently manage their new roles and responsibilities, including the significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of investors, our prospects may be adversely impacted. In addition, against this backdrop, it may be difficult to earn the confidence of prospective investors or strategic partners, threatening our ability to obtain much needed financing and hindering our exploration of strategic alternatives.

Turnover of senior management, and any inability to attract and retain qualified management and other key personnel, could impair our ability to implement our business plan.

As we continue our exploration of strategic alternatives, and potentially pursue transactions involving new business lines or industries, we expect significant turnover in senior management, including in the near term. Departures of members of our senior management team, coupled with the recent turnover in our board, will create significant continuity risks and challenges to our ability to operate our business, assess and manage risks and comply with applicable laws. If key members of our senior management team depart, which we believe is likely in the near term, it will be important that we attract and retain qualified managers promptly and develop and implement an effective succession plan. We expect to face significant competition in attracting experienced executives and other key personnel, and there can be no assurance that we will be able to do so. In addition, there are significant

15

Table of Contents

uncertainties as to how our controlled company status, transitional state of operations, financial condition and related matters will impact our ability to attract the necessary personnel and manage these succession risks. Depending on the circumstances of any management departures, it is also possible that we will be required to pay significant severance, adversely impacting our financial condition. Our urgent need to raise capital and engage with potential partners in strategic transactions magnify these risks. If we are unable to adequately address these concerns in the near term, and earn the confidence of potential investors and/or business partners, our prospects and financial condition would be adversely impacted.

Our consolidated financial statements have been prepared assuming that we will continue as a going concern.

Our ability to continue as a going concern will require us to obtain additional funding. Based on our current operating plans and existing working capital at December 31, 2022, our current liquidity is not sufficient to fund operations over the next twelve months from the date of the issuance of the accompanying consolidated financial statements. As a result, there is substantial doubt about our ability to continue as a going concern. Substantial additional financing will be needed by us to fund our operations and exploration of strategic alternatives in the near term. Although we currently estimate that available funds could be sufficient into early in the fourth quarter of 2023, we have based these estimates on assumptions that may prove to be wrong, and we could spend our available financial resources much faster than we currently expect. It is very difficult to project our current monthly cash burn rate given the transitional status of the Company as we explore strategic alternatives. The perception of our ability to continue as a going concern may make it more difficult for us to obtain financing for the continuation of our operations and could result in the loss of confidence by investors and employees. If we are unable to raise capital when needed or on acceptable terms, we will be unable to continue operations and may need to seek bankruptcy protection in the near term.

Our common stock may be delisted from The Nasdaq Capital Market which could negatively impact the price of our common stock, liquidity and our ability to access the capital markets.

Our common stock is currently listed on The Nasdaq Capital Market under the symbol “XCUR.” As previously disclosed, the Company has received numerous deficiency notes with respect to various Nasdaq listing requirements in the past year. These related to:

•Compliance with Nasdaq’s minimum bid price rule due to the Company’s stock trading below $1.00 for a sustained period of time. The Company effected a one-for-thirty reverse stock split on June 29, 2022 in order to attempt to raise the stock price. As of March 23, 2023, the Company’s stock price closed at $0.9761.

•Compliance with Nasdaq’s rule requiring stockholders’ equity of at least $2,500,000 based on the Company’s balance sheet as of June 30, 2022. The Company believes it is in compliance with this requirement based on its December 31, 2022 balance sheet, but there can be no assurance it will remain in compliance.

•Compliance with Nasdaq’s corporate governance requirements with respect to board and committee composition due to (i) the lack of a majority independent board, (ii) the lack of an audit committee comprised of three independent directors and (iii) the lack of a compensation committee comprised of at least two independent directors. With respect to the majority independence and the audit committee requirements, Nasdaq informed the Company that it was not entitled to a cure period and must submit a plan to regain compliance no later than April 10, 2023. Following the closing of the Private Placement, the Company qualifies for Nasdaq’s controlled company exemptions from the requirements to have a majority independent board and independent compensation committee. The Company still must have an audit committee comprised of three independent directors.

Even if the Company regains compliance with Nasdaq’s listing requirements and addresses the outstanding deficiency notices to Nasdaq’s satisfaction, there can be no assurance that the Company will remain in compliance with Nasdaq’s requirements and will not be delisted.

Table of Contents

If Nasdaq delists our securities from trading on its exchange for failure to meet the listing standards, we and our stockholders could face significant negative consequences including:

•limited availability of market quotations and liquidity for our securities;

•a determination that the common stock is a “penny stock” which would require brokers trading in the common stock to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for shares of common stock;

•a limited amount of analyst coverage, if any; and

•a decreased ability to issue additional securities or obtain additional financing in the future.

Delisting from The Nasdaq Capital Market could also result in other negative consequences, including the potential loss of institutional investor interest and make obtaining new financing much more challenging. In addition, fewer strategic opportunities may be available, particularly from counterparties that are interested in combining with a listed company.

We have a history of losses. We expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability, which could result in a decline in the market value of our common stock.

Since our inception in June 2011, we have devoted our resources to the development of SNA technology, and are currently exploring out-licensing opportunities and strategic alternatives to maximize stockholder value. We have had significant operating losses since our inception. As of December 31, 2022, we have generated an accumulated deficit of $191.5 million. For the years ended December 31, 2022 and 2021, our net loss was $2.6 million and $64.1 million, respectively. Substantially all of our losses have resulted from expenses incurred in connection with our research programs and from general and administrative costs associated with our operations.

We have not generated, and do not expect to generate, any product revenue for the foreseeable future and currently have no source of revenue or committed financing, and we expect to continue to incur significant operating losses for the foreseeable future. The amount of future losses is uncertain. Our future financial performance and condition are substantially dependent on the results of our ongoing exploration of strategic alternatives, and we cannot predict whether we will be successful.

We are pursuing asset out-licenses, asset sales and similar strategic transactions with respect to our historical assets. There can be no assurance that we will be successful in executing such a strategic transaction.

We continue to seek strategic alternatives for our therapeutic portfolios, with the goal of maximizing stockholder value of these assets. These strategic alternatives may include a variety of different business arrangements, such as the sale of certain of our assets, out-licensing, strategic partnerships, joint ventures, restructurings, divestitures, investments and other alternatives. We may not be able to identify or consummate a suitable transaction as a result of this review, or any transactions that we are able to identify and consummate may not provide material benefits to our stockholders. Based on the interest in these assets that we have seen to date, we do not currently expect any such transaction to provide significant value, at least in the near term.

Our business could be adversely affected by the effects of health epidemics, including the global COVID‐19 pandemic, in regions where we or third parties on which we rely have business operations.

Our business and operations could be adversely affected by the effects of health epidemics, including the ongoing COVID-19 pandemic, on our business activities performed by us or by third parties with whom we conduct business. Such effects could be more pronounced in regions where we have concentrations of business operations.

The spread of COVID-19, which continues to cause broad global impact, may materially affect us economically. The trading price for our shares as well as the trading prices of other biopharmaceutical companies, as well as the broader equity and debt markets overall, have been highly volatile as a result of the COVID-19 pandemic and the resulting impact on U.S. economic activities. Although the potential economic impact brought by, and the

17

Table of Contents

duration or subsequent reoccurrence of, the COVID-19 pandemic may be difficult to assess or predict, a widespread and prolonged pandemic could continue to result in significant disruption of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity. In addition, even after the COVID-19 pandemic has subsided, a recession or market correction that has occurred or may occur in the future because of the COVID-19 could materially affect our business and the value of our common stock. These conditions could challenge our ability to raise needed capital and our ability to identify and consummate strategic transactions to create value for stockholders.

The global outbreak of COVID-19 continues to rapidly evolve. The extent to which the COVID-19 pandemic or a similar pandemic will impact our business will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration and severity of the outbreak, the possibility of additional periods of increases or spikes in the number of COVID-19 cases, the introduction and spread of new variants of the virus, limitations on our ability to conduct our business in the ordinary course, any reopening plans and additional closures, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions for us, and the effectiveness of actions taken in the United States and other countries to contain and treat the disease, including, without limitation, the effectiveness and timing of vaccination initiatives in the United States and worldwide. The ultimate impact of the COVID-19 pandemic or a similar health pandemic is highly uncertain and subject to change; we continue to monitor the COVID-19 situation closely.

Our internal computer systems, or those of contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of our therapeutic development programs.

Despite the implementation of security measures, our internal computer systems and those of our contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Such events could cause interruptions of our operations. For instance, theft or other exposure of data may interfere with our ability to protect our intellectual property, trade secrets, and other information critical to our operations. We can provide no assurances that certain sensitive and proprietary information relating to one or more of our therapeutic candidates has not been, or will not in the future be, compromised. Although we have invested resources to enhance the security of our computer systems, there can be no assurances we will not experience additional unauthorized intrusions into our computer systems, or those of our contractors and consultants, that we will successfully detect future unauthorized intrusions in a timely manner, or that future unauthorized intrusions will not result in material adverse effects on our financial condition, reputation, or business prospects. Payments related to the elimination of ransomware may materially affect our financial condition and results of operations.

Certain data breaches must also be reported to affected individuals and the government, and in some cases to the media, under provisions of HIPAA, as amended by HITECH, other U.S. federal and state law, and requirements of non-U.S. jurisdictions, including the European Union Data Protection Directive. Financial penalties may also apply in some data breaches where noncompliance with the applicable law is identified.

To the extent that any disruption or security breach were to result in a loss of, or damage to, our data, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the development of our therapeutic candidates could be delayed.

Our information technology systems could face serious disruptions that could adversely affect our business.

Our information technology and other internal infrastructure systems, including corporate firewalls, servers, documents storage systems, backup systems, leased lines and connection to the Internet, face the risk of systemic failure that could disrupt our operations. A significant disruption in the availability of our information technology and other internal infrastructure systems could cause interruptions and delays in our operations.

Our business and operations could suffer in the event of system failures or unauthorized or inappropriate use of or access to our information technology systems.

Table of Contents

We are increasingly dependent on our information technology systems and infrastructure for our business. We collect, store and transmit sensitive information including intellectual property, proprietary business information and personal information in connection with business operations. The secure maintenance of this information is critical to our operations and business strategy. Some of this information could be an attractive target of criminal attack or unauthorized access and use by third parties with a wide range of motives and expertise, including organized criminal groups, “hacktivists,” patient groups, disgruntled current or former employees and others. Cyber-attacks are of ever-increasing levels of sophistication, and despite our security measures, our information technology systems and infrastructure may be vulnerable to such attacks or may be breached, including due to employee error or malfeasance.

The pervasiveness of cybersecurity incidents in general and the risks of cyber-crime are complex and continue to evolve. Although we are making significant efforts to maintain the security and integrity of our information systems and are exploring various measures to manage the risk of a security breach or disruption, there can be no assurance that our security efforts and measures will be effective or that attempted security breaches or disruptions would not be successful or damaging. Despite the implementation of security measures, our internal computer systems and those of our employees, contractors and consultants are vulnerable to damage or interruption from computer viruses, unauthorized or inappropriate access or use, natural disasters, pandemics (including COVID-19), terrorism, war, and telecommunication and electrical failures. Such events could cause interruption of our operations. For example, the loss or compromise of preclinical data for our therapeutic candidates could result in delays in our regulatory filings and development efforts, as well as delays in the commercialization of our products, and significantly increase our costs. To the extent that any disruption, security breach or unauthorized or inappropriate use or access to our systems were to result in a loss of or damage to our data, or inappropriate disclosure of confidential or proprietary information, including but not limited to patient, employee or vendor information, we could incur notification obligations to affected individuals and government agencies, liability, including potential lawsuits from patients, collaborators, employees, stockholders or other third parties and liability under foreign, federal and state laws that protect the privacy and security of personal information, and the development and potential commercialization of our therapeutic candidates could be delayed. Existing insurance arrangements may not provide protection for the costs that may arise from such loss or damage. Any long-term disruption in our ability to access our information technology systems could have a material adverse effect on our operations, our business, results of operations and stock price.

Increasing scrutiny and changing expectations from customers, regulators, investors, and other stakeholders with respect to our environmental, social and governance practices may impose additional costs on us or expose us to new or additional risks.

Companies are facing increasing scrutiny from customers, regulators, investors, and other stakeholders related to their environmental, social and governance practices. Investor advocacy groups, investment funds and influential investors are also increasingly focused on these practices, especially as they relate to the environment, health and safety, supply chain management, diversity and human rights. Failure to adapt to or comply with regulatory requirements or investor or stakeholder expectations and standards could negatively impact our reputation and the price of our ordinary shares.

Any of the factors mentioned above, or the perception that we or our suppliers, or contract manufacturers or collaborators have not responded appropriately to the growing concern for such issues, regardless of whether we are legally required to do so, may damage our reputation and have a material adverse effect on our business, financial condition, results of operations cash flows and/or ordinary share price.

Natural disasters or other unexpected events may disrupt our operations, adversely affect our results of operations and financial condition, and may not be covered by insurance.

The occurrence of one or more unexpected events, including fires, tornadoes, tsunamis, hurricanes, earthquakes, floods, and other forms of severe hazards in the United States or in other countries in which we or our suppliers or manufacturers operate or are located could adversely affect our operations and financial performance. These types of unexpected events could result in physical damage to and complete or partial closure of one or more of the manufacturing facilities operated by our contract manufacturers, or the temporary or long-term disruption in the supply of products, and/or disruption of our ability to deliver products to customers. Further, the long-term effects of climate change on general economic conditions and the pharmaceutical manufacturing and distribution industry in particular are unclear, and changes in the supply, demand or available sources of energy and the regulatory and other costs associated with energy production and delivery may affect the availability or cost of goods and services, including natural resources, necessary to run our businesses. Existing insurance arrangements may not provide protection for the costs that may arise from such events, particularly if such events are catastrophic in nature or occur in combination. Any long-term disruption in our ability to service our customers from one or more distribution centers or outsourcing facilities could have a material adverse effect on our operations, our business, results of operations and stock price.

Our current operations are concentrated in one location and any events affecting this location may have material adverse consequences.

Our current operations are located in our facilities situated in Chicago, Illinois. Any unplanned event, such as flood, fire, explosion, earthquake, extreme weather condition, medical epidemics, power shortage, telecommunication failure or other natural or man-made accidents or incidents that result in us being unable to fully utilize the facilities, may have a material adverse effect on our ability to operate our business, particularly on a daily basis, and have significant negative consequences on our financial and operating conditions. Loss of access to these facilities may result in increased costs, delays in the development of our therapeutic candidates or interruption of our business operations. As part of our risk management policy, we maintain insurance coverage at levels that we believe are appropriate for our business. However, in the event of an accident or incident at these facilities, we cannot assure you that the amounts of insurance will be sufficient to satisfy any damages and losses. If our facilities are unable to operate because of an accident or incident or for any other reason, even for a short period of time, any or all of our research and development programs may be harmed. Any business interruption may have a material adverse effect on our business, financial position, results of operations and prospects.

The investment of our cash, cash equivalents and fixed income marketable securities is subject to risks which may cause losses and affect the liquidity of these investments.

As of December 31, 2022, we had $9.8 million in cash, cash equivalents, and restricted cash. We invest our excess cash in U.S. government or U.S. government agency securities, floating rate and variable rate demand notes of U.S. and foreign corporations, and commercial paper. These investments are subject to general credit, liquidity, market and interest rate risks, including potential future impacts from economic, capital market or bank instability. We may from time to time have balances in bank accounts that are in excess of insured deposit limits, and could be subject to risks of bank failures. We may realize losses in the fair value of these investments, an inability to access cash in these investments for a potentially meaningful period, or a complete loss of these investments, which would have a negative effect on our financial statements.

In addition, should our investments cease paying or reduce the amount of interest paid to us, our interest income would suffer. The market risks associated with our investment portfolio may have an adverse effect on our results of operations, liquidity and financial condition.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired.

We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, the Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley Act, and the rules and regulations of The Nasdaq Capital Market. Pursuant to

20

Table of Contents

Section 404 of the Sarbanes-Oxley Act, or Section 404, we are required to perform system and process evaluation and testing of our internal control over financial reporting to allow our management to report on the effectiveness of our internal control over financial reporting. However, while we remain a non-accelerated filer or an emerging growth company, we will not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm.

During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective. Further, we may in the future discover weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements. Moreover, our internal controls over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. Moreover, we are aware that the remote working arrangements implemented in connection with the COVID-19 pandemic potentially present new areas of risk, and we continue to carefully monitor any impact to our internal controls and procedures.

Our limited resources and recent reductions in force, as well as the turnover in our board of directors and the potential for future management changes, present significant continuity risk and could impact our ability to maintain effective internal control over financial reporting.

If we are unable to assert that our internal control over financial reporting is effective, investors could lose confidence in the reliability of our financial statements, the market price of our stock could decline and we could be subject to sanctions or investigations by The Nasdaq Capital Market, the SEC or other regulatory authorities.

Risks Related to Intellectual Property

We currently license patent rights from Northwestern University. If Northwestern University does not properly or successfully obtain, maintain or enforce the patents underlying such licenses, or if they retain or license to others any competing rights, our competitive position and business prospects may be adversely affected.

We rely on intellectual property rights licensed from third parties to protect our technology. We are a party to a number of licenses that give us rights to third-party intellectual property that is necessary or useful for our business. In particular, we have a license from Northwestern University, which provides us the exclusive worldwide right under certain patents and patent applications owned by Northwestern University to exploit therapeutics and processes using nanoparticles, nanotechnology, microtechnology and nanomaterial-based constructs as therapeutics or accompanying therapeutics as a means of administration. To the extent we are successful in selling, licensing or otherwise generating value from our historical assets, it would depend significantly on the value of the rights licenses from Northwestern. We may also license additional third-party intellectual property in the future. Our success will depend in part on the ability of our licensors to obtain, maintain and enforce patent protection for our licensed intellectual property, and in particular, for those patents to which we have secured exclusive rights. Our licensors may not successfully prosecute the patent applications licensed to us. Even if patents issue or are granted, our licensors may fail to maintain these patents, may determine not to pursue litigation against other companies that are infringing these patents, or may pursue litigation less aggressively than we would. Further, we may not obtain exclusive rights, which would allow for third parties to develop competing therapeutics. Without protection for, or exclusive rights to, the intellectual property we license, other companies might be able to offer substantially identical therapeutics for sale, which could adversely affect our competitive business position and harm our business prospects.

We or our licensors, or any current or future strategic partners, may become subject to third-party claims or litigation alleging infringement of patents or other proprietary rights or seeking to invalidate patents or other proprietary rights, and we may need to resort to litigation to protect or enforce our patents or other proprietary

21

Table of Contents

rights, all of which could be costly, time consuming, delay or prevent the development and commercialization of our therapeutic candidates, or put our patents and other proprietary rights at risk.

We or our licensors, or any current or future strategic partners, may be subject to third-party claims for infringement or misappropriation of patent or other proprietary rights. We are generally obligated under our license agreements to indemnify and hold harmless our licensors for damages arising from intellectual property infringement by us. If we or our licensors, or any current or future strategic partners, are found to infringe a third-party patent or other intellectual property rights, we could be required to pay damages, potentially including treble damages, if we are found to have willfully infringed. In addition, we or our licensors, or any current or future strategic partners, may choose to seek, or be required to seek, a license from a third-party, which may not be available on acceptable terms, if at all. Even if a license can be obtained on acceptable terms, the rights may be non-exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us. If we fail to obtain a required license, we or any current or future collaborator may be unable to effectively market therapeutic candidates based on our technology, which could limit our ability to generate revenue or achieve profitability and possibly prevent us from generating revenue sufficient to sustain our operations. In addition, we may find it necessary to pursue claims or initiate lawsuits to protect or enforce our patent or other intellectual property rights. The cost to us in defending or initiating any litigation or other proceeding relating to patent or other proprietary rights, even if resolved in our favor, could be substantial, and litigation would divert our management’s attention. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could delay our research and development efforts and limit our ability to continue our operations.

If we were to initiate legal proceedings against a third-party to enforce a patent covering one of our therapeutics or our technology, the defendant could counterclaim that our patent is invalid or unenforceable. In patent litigation in the U.S., defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution. The outcome following legal assertions of invalidity and unenforceability during patent litigation is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on one or more of our therapeutics or certain aspects of our technology. Such a loss of patent protection could have a material adverse impact on our business. Patents and other intellectual property rights also will not protect our technology if competitors design around our protected technology without legally infringing our patents or other intellectual property rights.

It is also possible that we have failed to identify relevant third-party patents or applications. For example, U.S. applications filed before November 29, 2000 and certain U.S. applications filed after that date that will not be filed outside the U.S. remain confidential until patents issue. Patent applications in the U.S. and elsewhere are published approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our therapeutics or technology could have been filed by others without our knowledge. Additionally, pending patent applications which have been published can, subject to certain limitations, be later amended in a manner that could cover our SNA technology, our therapeutics or the use of our therapeutics. Third-party intellectual property right holders may also actively bring infringement claims against us. We cannot guarantee that we will be able to successfully settle or otherwise resolve such infringement claims. If we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or continue costly, unpredictable and time-consuming litigation and may be prevented from or experience substantial delays in marketing our therapeutics. If we fail in any such dispute, in addition to being forced to pay damages, we may be temporarily or permanently prohibited from commercializing any of our therapeutic candidates that are held to be infringing. We might, if possible, also be forced to redesign therapeutic candidates so that we no longer infringe the third-party intellectual property rights. Any of these events, even if we

22

were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business.

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.

We may also be subject to claims that former employees or other third parties have an ownership interest in our patents or other intellectual property. Litigation may be necessary to defend against these and other claims challenging inventorship or ownership. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and distraction to management and other employees.

If we fail to comply with our obligations under any license, collaboration or other agreements, we may be required to pay damages and could lose intellectual property rights that are necessary for developing and protecting our therapeutic candidates or we could lose certain rights to grant sublicenses.

Our current licenses impose, and any future licenses we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement, and other obligations on us. If we breach any of these obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages and the licensor may have the right to terminate the license, which could result in us being unable to develop, manufacture and sell therapeutics that are covered by the licensed technology or could enable a competitor to gain access to the licensed technology. Moreover, our licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing or otherwise violating the licensor’s rights in such unlicensed intellectual property. In addition, while we cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future therapeutics, if any, the amounts may be significant. The amount of our future royalty obligations will depend on the technology and intellectual property we use in therapeutics that we successfully develop and commercialize, if any. Therefore, even if we successfully develop and commercialize therapeutics, we may be unable to achieve or maintain profitability.

Risks Related to Government Regulation

We face potential liability related to the privacy and security of health information we obtain from clinical trials sponsored by us.

Most healthcare providers, including research institutions from which we have obtained patient health information, are subject to privacy and security regulations promulgated under HIPAA, as amended by the HITECH. We are not currently classified as a covered entity or business associate under HIPAA and thus are not directly subject to its requirements or penalties. However, any person may be prosecuted under HIPAA’s criminal provisions either directly or under aiding-and-abetting or conspiracy principles. Consequently, depending on the facts and circumstances, we could face substantial penalties if we receive or use individually identifiable health information from a HIPAA-covered healthcare provider or research institution or business associate that has not satisfied HIPAA’s requirements for disclosure of individually identifiable health information. In addition, we may maintain sensitive personally identifiable information, including health information, that we received throughout the clinical trial process, in the course of our research collaborations, and directly from individuals (or their healthcare providers) who enrolled in our patient assistance programs. As such, we may be subject to state laws requiring notification of affected individuals and state regulators in the event of a breach of personal information, which is a broader class of information than the health information protected by HIPAA.

If we or our contractors or consultants fail to comply with applicable federal, state or local regulatory requirements, we could be subject to a range of regulatory actions. Any threatened or actual government enforcement action could also generate adverse publicity and require that we devote substantial resources that could

23

Table of Contents

otherwise be used in other aspects of our business. Increasing use of social media could give rise to liability, breaches of data security or reputational damage.

We are subject to European data protection laws, including the European Union’s General Data Protection Regulation 2016/679, or GDPR. If we fail to comply with existing or future data protection regulations, our business, financial condition, results of operations and prospects may be materially adversely affected.

By virtue of our prior clinical trial activities in the United Kingdom and Europe, we are subject to European data protection laws, including the GDPR. The GDPR which came into effect on May 25, 2018, establishes new requirements applicable to the processing of personal data (i.e., data which identifies an individual or from which an individual is identifiable), affords new data protection rights to individuals (e.g., the right to erasure of personal data) and imposes penalties for serious breaches of up to 4% annual worldwide turnover or €20 million, whichever is greater. Individuals (e.g., study subjects) also have a right to compensation for financial or non-financial losses (e.g., distress). There may be circumstances under which a failure to comply with the GDPR, or the exercise of individual rights under the GDPR, would limit our ability to utilize clinical trial data collected on certain subjects. The GDPR imposes additional responsibility and liability in relation to our processing of personal data. This may be onerous and we may be unsuccessful in implementing all measures required by data protection authorities or courts in interpretation of the GDPR, which may materially adversely affect our business, financial condition, results of operations and prospects.

Risks Related to Ownership of Our Common Stock

The market price of our common stock has been, and is likely to continue to be, highly volatile, and you may not be able to resell your shares at or above the price you paid for them.

Our stock price will continue to be volatile. As a result of this volatility, investors may not be able to sell their common stock at or above the price paid for the shares. The market price for our common stock may be influenced by a variety of factors, including the other risks described in this section titled “Risk Factors” and the following:

•our ability or inability to raise additional capital and the terms on which we raise it;

•the development, execution and announcement of any proposed strategic alternative;

•investors may react negatively to our controlled company status and the influence of our controlling stockholder or our reconstituted board and/or our uncertain business strategy;

•strategic decisions by us or our competitors, such as acquisitions, divestitures, spin-offs, joint ventures, strategic investments or changes in business strategy;

•we are unable to achieve the perceived benefits of our Company as rapidly or to the extent anticipated by financial or industry analysts; and

•changes in general economic, industry, political and market conditions, including, but not limited to, the ongoing impact of the COVID-19 pandemic.

In addition, the stock markets in general, and the markets for pharmaceutical and biotechnology stocks in particular, have experienced extreme volatility that has been often unrelated to the operating performance of the issuer. These broad market and industry factors, such as those related to the COVID-19 pandemic and Russia’s invasion of Ukraine and retaliatory actions taken by the United States, NATO and others, may seriously harm the market price of our common stock, regardless of our operating performance.

Raising additional funds by issuing securities may cause dilution to existing stockholders and raising funds through lending and licensing arrangements may restrict our operations or require us to relinquish proprietary rights.

Until such time, if ever, as we can generate substantial revenues, we expect to attempt to finance our cash needs through a combination of equity offerings and debt financings. As discussed elsewhere, it may be very challenging to obtain equity or debt financing given the current transitional state of the Company. However, to the extent that we raise additional capital through the issuance of shares or other securities convertible into shares, our stockholders will be diluted. Future issuances of our common stock or other equity securities, or the perception that such sales may occur, could adversely affect the prevailing market price of our common stock and impair our ability to raise capital through future offerings of equity or equity-linked securities.

We are an “emerging growth company” and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company” as defined in the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including (1) not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, (2) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and (3) exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. In addition, as an emerging growth company, we are only required to provide two years of audited financial statements and two years of selected financial data. We expect to lose emerging growth company status at the end of this year. Even after we no longer qualify as an emerging growth company, we may still qualify as a “smaller reporting company” and/or “non-accelerated filer” which would allow us to take advantage of many of the same exemptions from disclosure requirements including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our share price may be more volatile.

Anti-takeover provisions in our charter documents and under the General Corporation Law of the State of Delaware could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our management.

Provisions in our amended and restated certificate of incorporation and our bylaws may delay or prevent an acquisition of us or a change in our management. These provisions include a classified board of directors, a prohibition on actions by written consent of our stockholders, and the ability of the Board of Directors of the Company, or the Board, to issue preferred stock without stockholder approval. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, or DGCL, which prohibits stockholders owning in excess of 15% of the outstanding combined organization voting stock from merging or combining with the combined organization. Although we believe these provisions collectively will provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our Board, they would apply even if the offer may be considered beneficial by some stockholders. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove then-current management by making it more difficult for stockholders to replace members of the Board, which is responsible for appointing the members of management.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended and restated certificate of incorporation provides that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for any of the following types of actions or proceedings under Delaware statutory or common law: derivative action or proceeding brought on our behalf, any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, any action asserting a claim arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws or any action asserting a claim that is governed by the internal affairs doctrine, in each case subject to the Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. This provision would not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended, or any other claims for which a court or forum other than the Court of Chancery has exclusive jurisdiction or for which the Court of Chancery does not have subject matter jurisdiction. Furthermore, Section 22 of the Securities Act of 1933, as amended, or the Securities Act, creates concurrent jurisdiction for federal and state courts over all Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. Our amended and restated certificate of incorporation also provides that any person purchasing or otherwise acquiring any interest in any shares of our common stock shall be deemed to have notice of and to have consented to this provision of our amended and restated certificate of incorporation.

This choice of forum provision may limit our stockholders’ ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents even though an action, if successful, might benefit our stockholders. Stockholders who do bring a claim in the Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. The Court of Chancery may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. If a court were to find this exclusive forum provision in our amended and restated certificate of incorporation to be inapplicable or unenforceable in any action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could have a material adverse effect on our business, financial condition or results of operations.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

We have incurred substantial losses during our history and do not expect to become profitable in the near future and we may never achieve profitability. Our net operating loss, or NOL, carryforwards generated in tax years beginning on or before December 31, 2017, are only permitted to be carried forward for 20 years under applicable U.S. tax law. Under the Tax Cuts and Jobs Act, as modified by the CARES Act, our federal NOLs generated in tax years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such federal NOLs is be limited to 80% of taxable income. In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOL, and other pre-change tax attributes (such as research tax credits) to offset its post-change income or taxes may be limited. We have experienced ownership changes in the past. We completed a review of our changes in ownership through December 31, 2022 and determined that we experienced an "ownership change" within the meaning of Section 382(g) during the fourth quarter of 2022. This ownership change has and will continue to subject our net operating loss carryforwards to an annual limitation, which will significantly restrict our ability to use them to offset our taxable income in periods following the ownership change.

We determined that at the date of the 2022 ownership change, we had a net unrealized built-in loss ("NUBIL"). The NUBIL was determined based on the difference between the fair market value of our assets and their tax basis at the ownership change date. Because of the NUBIL, certain deductions recognized during the five-year period

26

Table of Contents

beginning on the date of the IRC Section 382 ownership change (the "recognition period") are subject to the same limitation as the net operating loss carryforwards or certain other deductions.

In addition, we may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which are outside of our control. As a result, if we earn net taxable income, our ability to use our pre-change NOL carryforwards to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.

General Risk Factors

FINRA sales practice requirements may limit a stockholder’s ability to buy and sell our stock due to our low stock price.

The Financial Industry Regulatory Authority, or FINRA, has adopted rules requiring that, in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative or low-priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information. Under interpretations of these rules, FINRA has indicated its belief that there is a high probability that speculative or low-priced securities will not be suitable for at least some customers. If these FINRA requirements are applicable to us or our securities, which we believe they are, they may make it more difficult for broker-dealers to recommend that at least some of their customers buy our common stock, which may limit the ability of our stockholders to buy and sell our common stock and could have an adverse effect on the market for and price of our common stock.

If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. Our research coverage by securities and industry analysts is currently limited. In addition, because we did not become a reporting company by conducting an underwritten initial public offering of our common stock, security analysts of brokerage firms may not provide wider coverage of our Company. In addition, investment banks may be less likely to agree to underwrite secondary offerings on our behalf than they might if we became a public reporting company by means of an underwritten initial public offering, because they may be less familiar with our Company as a result of more limited coverage by analysts and the media, and because we became public at an early stage in our development. The failure to receive wider research coverage or support in the market for our shares will have an adverse effect on our ability to develop a liquid market for our common stock and the trading price for our stock would be negatively impacted.

In the event we obtain wider securities or industry analyst coverage, if any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, our intellectual property or our stock performance, or if our target studies and operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

Item 2. Properties.

Our corporate headquarters are located in Chicago, Illinois, where we lease approximately 30,000 square feet of office and laboratory space (the “Chicago Lease”). The Chicago Lease commenced on July 1, 2020, and expires on July 1, 2030. Under the lease agreement, we are given an option to extend the lease term for two additional successive periods of five years each.

We believe that this space is sufficient to meet our needs for the foreseeable future and that any additional or alternative space we may require will be available in the future on commercially reasonable terms.

Item 3. Legal Proceedings.

On December 13, 2021, Mark Colwell filed a putative securities class action lawsuit against the Company, David A. Giljohann and Brian C. Bock in the United States District Court for the Northern District of Illinois, captioned Colwell v. Exicure, Inc. et al., Case No. 1:21-cv-0663. On February 4, 2021, plaintiff filed an amended putative securities class action complaint. The amended complaint alleges that Dr. Giljohann and Mr. Bock made materially false and/or misleading statements related to the Company’s clinical programs purportedly causing losses to investors who acquired Company securities between January 7, 2021 and December 10, 2021. The amended complaint does not quantify any alleged damages but, in addition to attorneys’ fees and costs, plaintiff seeks to recover damages on behalf of himself and others who acquired the Company’s stock during the putative class period at allegedly inflated prices and purportedly suffered financial harm as a result. On March 20, 2023, the Court issued an Order appointing James Mathew as Lead Plaintiff, and Bleichmar Fonti & Auld LLP as Lead Counsel for the purported class. The parties are required to submit, within two weeks of that Order, a schedule to the Court governing the filing of a further amended complaint and the timing of defendants’ answer or response.

On March 1, 2022, Kapil Puri filed a shareholder derivative lawsuit on behalf of the Company in the United States District Court for the Northern District of Illinois, against Dr. Giljohann and Mr. Bock, Jeffrey L. Cleland, Elizabeth Garofalo, Bosun Hau, Bali Muralidhar, Andrew Sassine, Matthias Schroff, James Sulat and Timothy Walbert, captioned Puri v. Giljohann, et al., Case No. 1:22-cv-01083. On March 8, 2022, Yixin Sim filed a similar shareholder derivative lawsuit in the same court against the same individuals, captioned Sim v. Giljohann, et al., Case No. 1:22-cv-01217. On April 25,2022, Stourbridge Investments LLC filed a similar shareholder derivative lawsuit against the same individuals in the United States District Court for the District of Delaware, captioned Stourbridge Investments LLC v. Exicure, Inc. et al., Case No. 1:22-cv-00526. Based on similar factual allegations presented in the Colwell complaint, described above, the Puri, Sim, and Stourbridge complaints (collectively, the “Derivative Complaints”) allege that the defendants caused the Company to issue false and/or misleading statements in the proxy statement for its 2021 Annual Meeting of Stockholders regarding risk oversight, code of conduct, clinical program and compensation matters, among other things, in violation of federal securities law, and committed breaches of fiduciary duties. The Derivative Complaints also assert that Dr. Giljohann and Mr. Bock are liable for contribution under the federal securities laws. The Puri and Stourbridge complaints further assert state law claims for unjust enrichment, and the Puri complaint additionally asserts state law claims for abuse of control, gross mismanagement and corporate waste. The plaintiffs do not quantify any alleged damages in the Derivative Complaints, but seek restitution for damages to the Company, attorneys’ fees, costs, and expenses, as well as an order directing that certain proposals for strengthening board oversight be put to a vote of the Company’s shareholders.

All of the Derivative Cases have been stayed pending a decision on any motion to dismiss that may be filed in the Colwell case. In addition, the Stourbridge case has been administratively closed pending the decision on motion to dismiss that may be filed in the Colwell case.

We may also be a party to litigation and subject to claims incident to the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Overview

Historically, we have been an early-stage biotechnology company focused on developing nucleic acid therapies targeting ribonucleic acid against validated targets. In September 2022, we announced a significant reduction in force, suspension of preclinical activities and halting of all research and development, and that we were exploring strategic alternatives to maximize stockholder value. With respect to our historical assets, this includes continuing to explore out-licensing opportunities for cavrotolimod, our clinical-stage asset in immuno-oncology, as well as for our preclinical candidate associated with the SCN9A program for neuropathic pain.

While the foregoing efforts are continuing, we do not expect they will generate significant value for stockholders, at least in the near term. Therefore, we are engaging in a broader exploration of strategic alternatives. This effort involves exploring growth through transactions with potential partners that see opportunity in joining an existing, publicly-traded organization. We are exploring transactions both within our historical biotechnology and life science industry and in other industries unrelated to our historical operations.

Because we currently have no source of revenue or committed financing, we will require substantial additional funding within the next few months in order to continue our exploration of strategic alternatives and consummate any transactions that we may identify.

Operating, financing, and cash flow considerations

Since our inception in 2011, we have primarily funded our operations through sales of our securities, loans and collaborations. As of December 31, 2022, our cash, cash equivalents, and restricted cash were $9.8 million. Subsequent to December 31, 2022, we raised gross proceeds of $5.4 million on the closing of the Private Placement (or net proceeds of approximately $4.6 million after transaction expenses) and expect to use the net proceeds for general working capital purposes as we pursue strategic alternatives as well as for the payout for warrant put rights that were exercised as a result of the change of control.

Our current liquidity is not sufficient to fund operations over the next twelve months from the date of the issuance of the accompanying consolidated financial statements. As a result, there is substantial doubt about our ability to continue as a going concern. Substantial additional financing will be needed by us within the next few months to fund our operations and ongoing exploration of strategic alternatives and pursue any alternatives that we identify. If we are unable to raise capital, the Company could seek bankruptcy protection in the near term, which may result in the Company’s stockholders receiving no or very little value in respect of their shares of the Company’s common stock.

We expect to seek financing through a combination of equity offerings, and debt financings. However, it may be difficult to obtain financing given the Company’s current condition and uncertainty over its future direction.

Therefore, we may be unable to raise capital when needed or on favorable terms. Our failure to raise capital or enter into such other arrangements as and when needed would have a negative impact on our financial condition and our ability to continue operations.

Recent Developments

Restructuring

On September 26, 2022, we announced our commitment to a plan to wind down our existing preclinical programs, including the development of our SCN9A program, to suspend all of our research and development (“R&D”) activities, including suspension of all partnered programs, and to implement a reduction in force whereby we reduced approximately 66% of our then-existing workforce, as well as other cost-cutting measures (collectively, the “Plan”). The purpose of the Plan was to decrease expenses, thereby, extending our cash runway, and enable us to maintain a streamlined organization to support key corporate functions.

Change of Control

On February 24, 2023, following the satisfaction of closing conditions, including the approval by our stockholders at a Special Meeting of Stockholders held on December 15, 2022, we closed our private placement (the “Private Placement”) to CBI USA. Exicure received gross proceeds of approximately $5.4 million in connection with the close of the Private Placement (or net proceeds of approximately $4.6 million after transaction expenses) and expects to use the net proceeds for general working capital purposes as we pursue strategic alternatives as well as for the payout for warrant put rights that were exercised as a result of the change of control.

Following the closing of the Private Placement, CBI USA is the beneficial owner of approximately 50.4% of the Company’s outstanding shares, resulting in a "change of control" of Exicure under the applicable rules of Nasdaq. At closing, CBI USA designated three members to the Company’s board of directors effective as of February 24, 2023. Additional directors were subsequently appointed by the board, and our board of directors currently includes 6 members, only one of which (Matthias Schroff, our Chief Executive Officer) was a director prior to the closing of the Private Placement. We are currently relying on Nasdaq’s “controlled company” exception to the requirements that a majority of our board be independent and that we have an independent compensation committee and independent nominating committee or function.

Termination of Collaboration Agreements

On December 12, 2022 (the “Ipsen Termination Agreement Effective Date”), the Company and Ipsen entered into a Mutual Termination Agreement (the “Ipsen Termination Agreement”), pursuant to which the parties mutually agreed to terminate the Ipsen Collaboration Agreement. Following such termination, the parties will jointly own R&D Term IP (as defined in the Ipsen Collaboration Agreement) and Patents Covering the R&D Term IP (as defined in the Ipsen Collaboration Agreement), with each party owning an equal, undivided interest in and to such R&D Term IP and patents. As a result of the termination of the Ipsen Collaboration Agreement, the Company regained the ability to independently develop medicines targeting Angelman syndrome and Huntington’s disease while Ipsen retains the right to re-enter into the collaboration with the Company in Huntington’s Disease and Angelman’s Syndrome.

On December 13, 2022 (the “AbbVie Termination Agreement Effective Date”), the Company and Allergan entered into a letter agreement (the “AbbVie Termination Agreement”), pursuant to which the parties mutually agreed to terminate the AbbVie Collaboration Agreement. Following such termination, the Company transferred to Allergan all data, information, and reports made or generated by the Company in the course of performing activities under the Development Plan (as defined in the AbbVie Collaboration Agreement), and granted to Allergan all rights to transfer, publish, present, or otherwise publicly disclose any Collaboration Technology (as defined in the AbbVie Collaboration Agreement) and data made or generated by the Company in the course of performing activities under the Development Plan. As a result of the termination of the AbbVie Collaboration Agreement, the Company regained the ability to independently develop medicines targeting hair loss disorders.

Nasdaq Listing Requirements Deficiency Notices

As previously disclosed, the Company has received numerous deficiency notes with respect to various Nasdaq listing requirements in the past year. These related to:

•Compliance with Nasdaq’s minimum bid price rule due to the Company’s stock trading below $1.00 for a sustained period of time. The Company effected a one-for-thirty reverse stock split on June 29, 2022 in order to attempt to raise the stock price. As of March 23, 2023, the Company’s stock price closed at $0.9761.

•Compliance with Nasdaq’s rule requiring stockholders’ equity of at least $2,500,000 based on the Company’s balance sheet as of June 30, 2022. The Company believes it is in compliance with this requirement based on its December 31, 2022 balance sheet, but there can be no assurance it will remain in compliance.

•Compliance with Nasdaq’s corporate governance requirements with respect to board and committee composition due to (i) the lack of a majority independent board, (ii) the lack of an audit committee comprised of three independent directors and (iii) the lack of a compensation committee comprised of at least two independent directors. With respect to the majority independence and the audit committee requirements, Nasdaq informed the Company that it was not entitled to a cure period and must submit a plan to regain compliance no later than April 10, 2023. Following the closing of the Private Placement, the Company qualifies for Nasdaq’s controlled company exemptions from the requirements to have a majority independent board and independent compensation committee. The Company still must have an audit committee comprised of three independent directors, which it believes it currently does following the additional board appointments after the closing of the Private Placement, and intends to reply to Nasdaq promptly.

Even if the Company regains compliance with Nasdaq’s listing requirements and addresses the outstanding deficiency notices to Nasdaq’s satisfaction, there can be no assurance that the Company will remain in compliance with Nasdaq’s requirements and will not be delisted.

Basis of Presentation

The audited financial statements of Exicure, Inc. for the fiscal years ended December 31, 2022 and 2021, contained herein, include a summary of our significant accounting policies and should be read in conjunction with the discussion below.

Segment Reporting

We view our operations and manage our business as one segment, which for the periods presented was the discovery, research and development of treatments based on our SNA technology.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the revenue and expenses incurred during the reported periods. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not apparent from other sources. Changes in estimates are reflected in reported results for the period in which they become known. Actual results may differ from these estimates under different assumptions or conditions.

Our significant judgments and estimates are detailed below, and our significant accounting policies are more fully described in Note 2 of the accompanying consolidated financial statements.

Revenue recognition

Revenue allocated to performance obligations relating to provision of research and development activities is recognized as the performance obligations are satisfied using an input method to measure progress, based on an estimate of the percentage of completion of the project based on the actual hours incurred on the project as a percentage of the total expected project hours. The determination of the percentage of completion requires management to estimate the total expected project hours. A detailed estimate of the total expected project hours is re-assessed every reporting period based on the latest project plan and discussions with project teams. If a change in facts or circumstances occurs, the estimate will be adjusted and the revenue will be recognized based on the revised estimate. The difference between the cumulative revenue recognized based on the previous estimate and the revenue recognized based on the revised estimate would be recognized as an adjustment to revenue in the period in which the change in estimate occurs. Determining the estimate of total project hours requires significant judgment and may have a significant impact on the amount and timing of revenue recognition. For example, revenue recognized under the AbbVie Collaboration Agreement for the year ended December 31, 2021 was $(2.8) million due primarily to the cumulative catchup adjustment (reduction) of revenue recorded in connection with a change in estimate that occurred during the third quarter of 2021 (see Note 3 to the accompanying consolidated financial statements).

Components of Statements of Operations

Revenue

For the year ended December 31, 2022, the Company’s revenue was generated from its collaborations with Ipsen and AbbVie, which were terminated in the fourth quarter. Following the termination of the AbbVie and Ipsen agreements in the fourth quarter of 2022, as discussed above, we have no current source of revenue. We have never generated any commercial product revenue and do not expect to generate any product revenue.

Research and development expense

Research and development expense consists of costs associated with our research activities, including basic research on our SNA platform, discovery and development of novel SNAs as prospective therapeutic candidates, preclinical and clinical development activities for SNAs we have nominated for clinical development as well as maintaining and protecting our intellectual property. Our research and development expenses in the periods presented include:

•employee-related expenses, including salaries, bonuses, benefits and equity-based compensation expense;

•early research and development expenses incurred under arrangements with third parties, such as contract research organizations, contract manufacturing organizations, and consultants;

•preclinical and clinical development expenses with third parties such as contract research organizations, contract manufacturing organizations, and consultants;

•costs of maintaining and protecting our intellectual property portfolio, including legal advisory fees, license fees, sublicense fees, patent maintenance and other similar fees;

•laboratory materials and supplies;

•facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities, depreciation of leasehold improvements and equipment and laboratory and other supplies.

35

Table of Contents

We expense research and development costs as they are incurred. A significant portion of our research and development costs were not tracked by project as they benefit multiple projects or our technology. As previously announced, we halted all research and development activities in 2022.

General and administrative expense

General and administrative expense consists primarily of salaries and related benefits, including equity-based compensation, related to our executive, finance, legal, business development and support functions. Other general and administrative expenses include travel expenses, professional fees for auditing, tax and legal services and allocated facility-related costs not otherwise included in research and development expenses.

Dividend income

Dividend income consists of income earned on our money market funds that are recorded as cash equivalents on our consolidated balance sheets.

Interest income

Interest income consists of income earned on our available for sale securities that are recorded as short-term investments on our consolidated balance sheets, as well as income earned on our cash balances.

Interest expense

Interest expense includes amounts pursuant to the MidCap Credit Agreement (as defined below). All outstanding indebtedness and other obligations under the MidCap Credit Agreement (as defined below) was repaid in full on March 15, 2022.

Other expense, net

Other expense, net mostly consists of gains and losses on foreign currency transactions and gains and losses on the sale of capital assets.

Collaboration revenue:

Collaboration revenue was $28.8 million during the year ended December 31, 2022, reflecting an increase of $29.3 million, or 6,068%, from collaboration revenue of $(0.5) million for the year ended December 31, 2021. The increase in collaboration revenue of $29.3 million is due to the recognition of the remaining deferred revenue related to the AbbVie Collaboration Agreement of $13.9 million and the Ipsen Collaboration Agreement of $15.4 million in connection with the terminations of those collaboration agreements in December 2022. This revenue resulted from an accounting adjustment, did not reflect any new cash proceeds to the Company and will not recur. Following these terminations, we currently have no source of revenues.

Refer to Note 3, Collaborative Research and License Agreements, of the accompanying consolidated financial statements for more information regarding revenue recognition for the AbbVie Collaboration Agreement and Ipsen Collaboration Agreement.

Table of Contents

Our ability to generate revenues in the future is dependent on our ability to successfully explore and execute strategic alternatives. Therefore, there is substantial uncertainty as to how, when or if we might be able to generate revenues in the future.

Research and development expense

The following table summarizes our research and development expenses incurred during the periods indicated:

Year EndedDecember 31,

Facilities, depreciation, and other expenses 4,119 4,068 51 1 %

Full time employees 5 37 (32)

Research and development expense was $19.8 million for the year ended December 31, 2022, reflecting a decrease of $29.2 million, or 60%, from research and development expense of $49.0 million for the year ended December 31, 2021. The decrease in research and development expense for the year ended December 31, 2022 of $29.2 million reflects fewer clinical, preclinical, and discovery program activities and a reduction in headcount resulting from the restructuring activities that were announced in December 2021 and September 2022. More specifically, the decrease in research and development expense for the year ended December 31, 2022 of $29.2 million was due to a decrease in costs related to our clinical development programs of $16.1 million, lower platform and discovery-related expense of $7.5 million, and lower employee-related expenses of $5.7 million.

The decrease in clinical development programs expense for the year ended December 31, 2022 of $16.1 million was primarily due to lower manufacturing and toxicology study costs in connection with IND-enabling and Phase 1 clinical trial preparation activities for the XCUR-FXN program, which we indefinitely suspended in December 2021. In addition, lower clinical trial costs in connection with our Phase 1b/2 clinical trial for cavrotolimod (AST-008), which we began to wind down in December 2021, contributed to the decrease in clinical development program expense as compared to the prior-year period.

The decrease in platform and discovery-related expense for the year ended December 31, 2022 of $7.5 million was mostly due to lower costs for materials, reagents, and supplies in connection with a reduction in headcount and fewer discovery and preclinical program activities, the absence of the license fee paid to Northwestern University of $3.0 million in the prior year period in connection with the receipt of the upfront payment of $20.0 million from Ipsen, and lower intellectual property costs, as compared to the prior-year period.

The decrease in employee-related expense for the year ended December 31, 2022 of $5.7 million was due to lower compensation and related costs in connection with a lower headcount during the period resulting from the restructuring activities that were announced in December 2021 and September 2022, partially offset by retention award expense.

Table of Contents

General and administrative expense

Year EndedDecember 31,

Full time employees 8 9 (1)

General and administrative expense was $10.9 million for the year ended December 31, 2022, representing a decrease of $2.2 million, or 17%, from $13.1 million for the year ended December 31, 2021. The decrease for the year ended December 31, 2022 is mostly due to lower compensation and related costs in connection with a lower headcount during the period resulting from the restructuring activities that were announced in December 2021, as well as lower costs for accounting, director fees, and investor relations. These lower costs in the current year period were partially offset by higher retention award expense, as well as higher consultant and advisory costs.

Interest expense

The decrease in interest expense of $1.1 million for the year ended December 31, 2022 is in connection with the repayment in full of all outstanding indebtedness and other obligations under the MidCap Credit Agreement (as defined below) on March 15, 2022.

Provision for income taxes

The effective tax rate for the year ended December 31, 2022 of (8.8)% is attributable to the fact that the Company is subject to the IRC Section 174 regulations requiring companies to capitalize certain research and experimental expenditures and IRC Section 382 loss limitation rules on our ability to utilize net operating losses to offset the capitalization requirement. The effective income tax rate for the year ended December 31, 2021 was 0% because the Company generated tax losses and provided a full valuation allowance against its deferred tax assets to an amount that is more likely than not to be realized.

We completed a review of our changes in ownership through December 31, 2022 and determined that we experienced an "ownership change" within the meaning of Section 382(g) during the fourth quarter of 2022. This ownership change has and will continue to subject our net operating loss carryforwards to an annual limitation, which will significantly restrict our ability to use them to offset our taxable income in periods following the ownership change. In general, the annual use limitation equals the aggregate value of our stock at the time of the ownership change multiplied by a specified tax-exempt interest rate.

Liquidity and Capital Resources

As of December 31, 2022, our cash, cash equivalents, and restricted cash were $9.8 million. We have no current source of revenues or committed financing. Subsequent to December 31, 2022, we received gross proceeds of approximately $5.4 million in connection with the close of the Private Placement (or net proceeds of approximately $4.6 million after transaction expenses) and expect to use the net proceeds for general working capital purposes as we pursue strategic alternatives as well as for the payout for warrant put rights that were exercised as a result of the change of control.

Our current liquidity is not sufficient to fund operations over the next twelve months from the date of the issuance of the accompanying consolidated financial statements. As a result, there is substantial doubt about our ability to continue as a going concern.

We believe that our existing cash and cash equivalents (including the proceeds received in February 2023 in connection with the closing of the Private Placement) could enable us to fund our operating expenses into the beginning of the fourth quarter of 2023. However, this estimate is based on assumptions about how we can limit spending that may prove to be wrong and it is very difficult to project our current cash burn rate given the transitional status of the Company as we explore strategic alternatives and this estimate may prove inaccurate and we may expend our limited resources sooner. Depending on the direction of our review of strategic alternatives, we

39

Table of Contents

may use our available resources sooner than we currently expect. The Company has already engaged in significant cost reductions, so our ability to further cut costs and extend our operating runway is limited. As a result, substantial additional financing will be needed by us within the next few months to pay our expenses, fund our ongoing exploration of strategic alternatives and pursue any alternatives that we identify. If we are unable to raise sufficient capital, the Company could seek bankruptcy protection in the near term, which may result in the Company’s stockholders receiving no or very little value in respect of their shares of the Company’s common stock.

We expect to seek financing through a combination of equity offerings and debt financings. However, it may be difficult to obtain financing given the Company’s current financial condition and lack of sources of revenues and uncertainty over its future direction. Traditional capital markets sources of funding may not be available to us in these circumstances. Therefore, we may be unable to raise capital at all, when needed or on favorable terms.

To the extent that we do raise additional capital, the ownership interest of our stockholders may be materially diluted, and the terms of such securities could include liquidation or other preferences that adversely affect the rights of our stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specified actions that otherwise might be in our best interests. Further, the global financial markets have experienced significant disruptions over the past couple years due to the COVID-19 pandemic, the ongoing conflict between Russia and Ukraine, worsening global macroeconomic conditions, including actions taken by central banks to counter inflation, volatility in the capital markets, instability in the banking industry and related market uncertainty, may impact our ability to obtain additional financing when needed on favorable terms or at all.

Private Placements

In May 2022, we entered into a securities purchase agreement with certain accredited investors, pursuant to which we issued and sold 867,369 shares of common stock, par value $0.0001 per share, at a purchase price of $5.81 per share for net proceeds of approximately $4.9 million.

In September 2022, we entered into a securities purchase agreement with CBI USA with respect to the Private Placement, which subsequently closed in February 2023.

MidCap Facility

On March 15, 2022, we repaid in full all outstanding indebtedness and other obligations under our Credit and Security Agreement, dated as of September 25, 2020, as amended on October 21, 2020, July 30, 2021, September 30, 2021, and December 10, 2021, with MidCap Financial Trust, as agent, and the lenders party thereto from time to time, or the MidCap Credit Agreement, and the other Financing Documents (as defined in the MidCap Credit Agreement), including but not limited to the outstanding principal balance of $7.5 million and an exit fee of approximately $0.5 million, and terminated all obligations thereunder (other than with respect to any obligations that are expressly specified to survive the termination).

Cash Flows

The following table shows a summary of our cash flows for the years ended December 31, 2022 and 2021:

Years EndedDecember 31,

Net cash used in operating activities $ (35,658) $ (34,819)

Net cash provided by investing activities 4,696 43,085

Net cash (used in) provided by financing activities (3,105) 1,116

40

Table of Contents

Operating activities

Net cash used in operating activities was $35.7 million and $34.8 million for the years ended December 31, 2022 and 2021, respectively. The slight increase in cash used in operating activities for the year ended December 31, 2022 of $0.8 million was primarily due to the absence of the prior-year period receipt of the upfront payment of $20.0 million from Ipsen in connection with the Ipsen Collaboration Agreement (net of $3.0 million license fee paid to Northwestern as a result) and the prepayment of the premium for directors and officers run-off insurance policy coverage in the fourth quarter of 2022 in anticipation of the Private Placement closing, mostly offset by lower cash used for working capital.

Investing activities

Net cash provided by investing activities was $4.7 million and $43.1 million for the years ended December 31, 2022 and 2021, respectively. The decrease in cash provided by investing activities of $38.4 million was primarily due to a decrease in proceeds from the maturity, net of purchases, of available-for-sale securities.

Financing activities

Net cash used in financing activities of $3.1 million for year ended December 31, 2022 is primarily due to the repayment in full of all outstanding indebtedness and other obligations under the MidCap Credit Agreement, partially offset by net proceeds of approximately $4.9 million received in connection with the May 2022 private placement transaction.

Net cash provided by financing activities of $1.1 million for the year ended December 31, 2021 is primarily due to the net proceeds we received of $10.4 million in connection with the sale of common stock and warrants in a registered direct offering in December 2021, as well as proceeds received from the exercise of stock options and the issuance of common stock in connection with our employee stock purchase plan, mostly offset by the prepayment of $10 million of the outstanding principal balance associated with our MidCap Credit Agreement in December 2021.

Going Concern

In accordance with Accounting Standards Codification 205-40, Going Concern, we have evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. In the absence of a significant source of recurring revenue, our continued viability is dependent on our ability to continue to raise additional capital to finance our operations. As discussed above, there are substantial uncertainties about our ability to raise such financing.

Contractual Obligations and Commitments

Chicago Lease

In February 2020, we entered into a new lease signed in February 2020 to secure approximately 30,000 square feet of office and laboratory space at 2430 N. Halsted St., Chicago, Illinois, or the Chicago Lease. The Chicago Lease commenced on July 1, 2020, which is when the premises leased thereunder were ready for occupancy, and expires 10 years from July 1, 2020 with an option to renew for two additional successive periods of five years each.

The initial annual base rent during the original term of the Chicago Lease is approximately $1.1 million for the first 12-month period of the original term, payable in monthly installments beginning on the lease commencement. Base rent thereafter is subject to annual increases of 3%, for an aggregate amount of $12.8 million over the initial term. We must also pay our proportionate share of certain operating expenses and taxes for each calendar year during the term. During the first 12 months, the base rent and our proportionate share of operating expenses and taxes are subject to certain abatements.

In connection with the Chicago Lease, we will maintain a letter of credit for the benefit of the landlord in an initial amount of $1.2 million, which amount is subject to reduction over time, which is secured by a restricted certificate of deposit account and presented within other noncurrent assets on our consolidated balance sheet at

December 31, 2022.

Warrants

Following the closing of the Private Placement, a holder of warrants to purchase 526,151 shares of common stock at a price of $8.1031 per share that were acquired in the December 2021 registered-direct offering transaction exercised their put option within 30 days of the closing of the Private Placement (February 24, 2023), to receive a cash payout for the outstanding warrants in the amount of the Black-Scholes value of each warrant as prescribed in the warrant agreement (or $0.8 million in the aggregate). This obligation remains outstanding as of the date of the filing of this Annual Report of Form 10-K.

Other

We also have obligations to make future payments to Northwestern that become due and payable on the achievement of certain commercial milestones. Based on the terminations of our collaborations with Ipsen and AbbVie, we currently do not anticipate any such milestone payments becoming due.

JOBS Act

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Under the JOBS Act, an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.

In addition, as an emerging growth company, we will not be required to provide an auditor’s attestation report on our internal control over financial reporting in future annual reports on Form 10-K as otherwise required by Section 404(b) of the Sarbanes-Oxley Act.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Exicure, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Exicure, Inc. and subsidiary (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations, comprehensive loss, changes in stockholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2022, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has incurred significant expenses and negative cash flows since inception and its current liquidity is not sufficient to fund operations over the next twelve months, which raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2014.

(in thousands, except share and per share data)

1. Description of Business and Basis of Presentation

Description of Business

Exicure, Inc. has historically been an early-stage biotechnology company focused on developing nucleic acid therapies targeting ribonucleic acid against validated targets. In September 2022, the Company announced a significant reduction in force, suspension of preclinical activities and halting of all research and development, and that the Company was exploring strategic alternatives to maximize stockholder value. With respect to the Company’s historical assets, this includes continuing to explore out-licensing opportunities for cavrotolimod, the Company’s clinical-stage asset in immuno-oncology, as well as for the Company’s preclinical candidate associated with the SCN9A program for neuropathic pain.

While the foregoing efforts are continuing, the Company does not expect they will generate significant value for stockholders, at least in the near term. Therefore, the Company is engaging in a broader exploration of strategic alternatives. This effort involves exploring growth through transactions with potential partners that see opportunity in joining an existing, publicly-traded organization. The Company is exploring transactions both within its historical biotechnology and life science industry and in other industries unrelated to its historical operations.

Throughout these consolidated financial statements, the terms the “Company,” and “Exicure” refer to Exicure, Inc. and where appropriate, its wholly owned subsidiary, Exicure Operating Company. Exicure Operating Company holds all material assets and conducts all business activities and operations of Exicure, Inc.

Basis of Presentation

The accompanying consolidated financial statements as of December 31, 2022 and 2021, and for the years then ended, have been presented in conformity with generally accepted accounting principles in the United States (“GAAP”).

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Exicure, Inc. and its wholly owned subsidiary, Exicure Operating Company. All intercompany transactions and accounts are eliminated in consolidation.

Reverse Stock Split

The Company effected a reverse stock split of its Common Stock at a ratio of 1-for-30 as of 5:00 p.m. Eastern Time on June 29, 2022. No fractional shares were issued in connection with the reverse stock split. Stockholders of record who would otherwise be entitled to receive a fractional share received a cash payment in lieu thereof. All information presented in the accompanying consolidated financial statements, unless otherwise indicated herein, assumes a 1-for-30 reverse stock split of the Company’s outstanding shares of Common Stock, and unless otherwise indicated, all such amounts and corresponding conversion price or exercise price data set forth herein have been adjusted to give effect to such assumed reverse stock split.

Going Concern

At each reporting period, the Company evaluates whether there are conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern for a period of one year after the date that the financial statements are issued. The Company is required to make certain additional disclosures if it concludes substantial doubt exists and it is not alleviated by the Company’s plans or when its plans alleviate substantial doubt about the Company’s ability to continue as a going concern.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern for a period of one year after the date that the financial statements are issued. As of December 31, 2022, the Company has generated an accumulated deficit of $191,486 since inception and expects to incur significant expenses and negative cash flows for the foreseeable future. As of December 31, 2022, the Company’s cash, cash equivalents, and restricted cash were $9,777. Management believes that given the Company’s current cash position, operating plans and forecasted negative cash flows from operating activities over the next twelve months, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date these financial statements are issued. The Company has no committed sources of additional capital at this time and substantial additional financing will be needed by the Company to fund its operations.

Management believes that existing cash and cash equivalents could enable the Company to fund its operating expenses into the beginning of the fourth quarter of 2023. However, this estimate is based on assumptions about how the Company can limit spending that may prove to be wrong. It is very difficult to project the Company’s current cash burn rate given the transitional status of the Company and this estimate may prove inaccurate. Depending on the direction of the Company’s review of strategic alternatives, the Company may use available resources sooner than management currently expects. The Company has already engaged in significant cost reductions, so our ability to further cut costs and extend the Company’s operating runway is limited. As a result, substantial additional financing will be needed by the Company within the next few months to pay expenses, fund the ongoing exploration of strategic alternatives and pursue any alternatives that may be identified. There can be no assurance that such additional financing will be available and, if available, can be obtained on acceptable terms.

The accompanying consolidated financial statements have been prepared as though the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

Use of Estimates

The preparation of the 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 contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on certain assumptions which it believes are reasonable in the circumstances and while actual results could differ from those estimates, management does not believe that any change in those assumptions in the near term would have a significant effect on the Company’s financial position, results of operations or cash flows. Actual results in future periods could differ from those estimates.

2. Significant Accounting Policies

Cash, cash equivalents, and short-term investments

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company’s short-term investments have initial maturities of greater than three months from date of purchase. The Company classifies its marketable debt security investments as “available-for-sale” and carries them at fair market value based upon prices on the last day of the fiscal period for identical or similar items. The Company records unrealized gains and losses on marketable debt securities in other comprehensive income (loss) as a component of stockholders’ equity until realized. Any premium or discount arising at purchase is amortized and/or accreted to interest income and/or interest expense over the life of the of the underlying security. Realized gains and losses are included in other income, net. The Company uses the specific identification method to determine the cost of securities sold.

Restricted cash

The Company secures a standby letter of credit with a restricted certificate of deposit account as part of its Chicago lease agreement. The Company considers the restricted certificate of deposit account in the amount of $1,200 to be restricted cash because its use to the Company is contractually limited and presents the balance within other noncurrent assets on the accompanying consolidated balance sheet at December 31, 2022.

Fair value of financial instruments

The Company has estimated the fair value of its financial instruments. The carrying amounts for cash, cash equivalents, and accounts payable approximate their fair value due to the relatively short-term nature of these instruments. The Company records short-term investments at their estimated fair value based on quoted market prices for identical or similar instruments.

Concentrations of credit risk and other risks and uncertainties

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, short-term investments, and accounts receivable. The Company places its cash, cash equivalents, and short-term investments with reputable financial institutions. The Company primarily invests its excess cash in debt instruments of corporations, the U.S. Treasury, financial institutions, and U.S. government agencies with strong credit ratings and an investment grade rating at or above a long-term rating of Aa3/AA- and a short-term rating of P1/A1. The Company has established guidelines relative to diversification and maturities that maintain safety and liquidity. The Company periodically reviews and modifies these guidelines to maximize trends in yields and interest rates without compromising safety and liquidity. The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds. The Company has no financial instruments with off-balance sheet risk of loss.

For the year ended December 31, 2022, the Company’s revenue was generated from its collaborations with Ipsen and AbbVie, which were terminated in the fourth quarter.

The Company is currently not profitable and no assurance can be provided that it will ever be profitable. The Company’s research and development activities have required significant investment since inception and operations are expected to continue to require cash investment in excess of its revenues. See also Note 1, Going Concern, for more information.

The Company is subject to risks common to biotechnology firms including, but not limited to, new and disruptive technological innovations, dependence on key personnel, protection of proprietary technology, the validity of and continued access to its owned and licensed intellectual property, limitations on the supply of critical materials, compliance with governmental regulations and market acceptance. The Company is also subject to risks associated with its exploration of strategic alternatives including, but not limited, the inability to identify any

(in thousands, except share and per share data)

transactions that will generate value for stockholders, incurrence of excessive costs in seeking to identify and pursue transactions and the possibility that any transaction the Company does pursue will not provide anticipated benefits.

Property and equipment

Property and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the various classes of property and equipment, which range from three to seven years. Leasehold improvements are amortized using the straight-line method over the shorter of the remaining terms of the respective leases or the estimated lives of the assets. Depreciation begins at the time the asset is placed in service.

Property and equipment are reviewed for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.No impairment losses were recorded from inception in December 2011 through December 31, 2022.

Warrants

The Company accounts for freestanding warrants within stockholder’s equity or as liabilities based on the characteristics and provisions of each instrument. The Company evaluates outstanding warrants in accordance with Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity, and ASC 815, Derivatives and Hedging. If none of the criteria in the evaluation in these standards are met, the warrants are classified as a component of stockholders’ equity and initially recorded at their grant date fair value without subsequent remeasurement. Warrants that meet the criteria are classified as liabilities and remeasured to their fair value, estimated using the Black-Scholes option-pricing model, at the end of each reporting period with changes in the fair value of the liability recorded in other income (expense), net in the consolidated statements of operations.

Revenue recognition

Under ASC 606, Revenue from Contracts with Customers, the Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that are within the scope of ASC 606, the Company performs the following five steps:

1.Identify the contract with the customer. A contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights and obligations regarding the goods or services to be transferred and identifies the related payment terms, (ii) the contract has commercial substance, and (iii) the Company determines that collection of substantially all consideration for goods and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. The Company applies judgment in determining the customer’s intent and ability to pay, which is based on a variety of factors including the customer’s historical payment experience, or in the case of a new customer, published credit and financial information pertaining to the customer.

2.Identify the performance obligations in the contract. Performance obligations promised in a contract are identified based on the goods and services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other available resources, and are distinct in the context of the contract, whereby the transfer of the good or service is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised goods and services, the Company must apply judgment to determine whether promised goods and services are both capable of being distinct and distinct in the context of the contract. If these criteria are not met, the promised goods and services are accounted for as a combined performance obligation.

3.Determine the transaction price. The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring goods and services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable

54

Table of Contents

EXICURE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share data)

consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method, depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Any estimates, including the effect of the constraint on variable consideration, are evaluated at each reporting period for any changes. Determining the transaction price requires significant judgment.

4.Allocate the transaction price to performance obligations in the contract. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. However, if a series of distinct services that are substantially the same qualifies as a single performance obligation in a contract with variable consideration, the Company must determine if the variable consideration is attributable to the entire contract or to a specific part of the contract. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation on a relative standalone selling price basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a single performance obligation. The consideration to be received is allocated among the separate performance obligations based on relative standalone selling prices.

5.Recognize revenue when or as the Company satisfies a performance obligation. The Company satisfies performance obligations either over time or at a point in time. Revenue is recognized over time if either (i) the customer simultaneously receives and consumes the benefits provided by the entity’s performance, (ii) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or (iii) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the related performance obligation is satisfied at a point in time by transferring the control of a promised good or service to a customer. Examples of control are using the asset to produce goods or services, enhance the value of other assets, or settle liabilities, and holding or selling the asset.

Revenue allocated to performance obligations relating to provision of research and development activities is recognized as the performance obligations are satisfied using an input method to measure progress, based on an estimate of the percentage of completion of the project based on the actual hours incurred on the project as a percentage of the total expected project hours. The determination of the percentage of completion requires management to estimate the total expected project hours. A detailed estimate of the total expected project hours is re-assessed every reporting period based on the latest project plan and discussions with project teams. If a change in facts or circumstances occurs, the estimate will be adjusted and the revenue will be recognized based on the revised estimate. The difference between the cumulative revenue recognized based on the previous estimate and the revenue recognized based on the revised estimate would be recognized as an adjustment to revenue in the period in which the change in estimate occurs. Determining the estimate of total project hours requires significant judgment and may have a significant impact on the amount and timing of revenue recognition.

Licenses 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 revenues from consideration allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the licenses. For licenses that are combined with other promises, the Company utilize 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. 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 the probability of reaching the milestones and estimates the amount to be included in the

55

Table of Contents

EXICURE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share data)

transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur in the future, 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 and therefore revenue recognized is constrained as management is unable to assert that a reversal of revenue would not be possible. The transaction price is then allocated to each performance obligation on a relative standalone 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 collaboration revenues and earnings in the period of adjustment. To date, the Company has not recognized any milestone payment revenue from any of its collaboration agreements.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on levels of sales, and the license is deemed to be the predominant item to which the 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 resulting from any of its collaboration agreements.

Equity-based compensation

The Company measures the cost of equity-based awards at fair value and records the cost of the awards, net of estimated forfeitures, on a straight-line basis over the requisite service period. The Company measures fair value for all common stock options using the Black-Scholes option-pricing model. The fair value of common stock option awards is affected by the valuation assumptions, including the expected volatility based on comparable market participants, expected term of the common stock option, risk-free interest rate, and expected dividends. For all equity-based awards, the fair value measurement date is the date of grant and the requisite service period is the period over which the recipient is required to provide service in exchange for the equity-based awards, which is generally the vesting period.

Segments and geographic information

The Company has determined it has one reporting segment. Disaggregating the Company’s operations is impracticable because the Company’s research and development activities and its assets overlap and management reviews its business as a single operating segment. Thus, discrete financial information is not available by more than one operating segment. All long-lived assets of the Company are located in the United States.

Leases

The Company determines if an arrangement is a lease at contract inception. Operating lease assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized on the balance sheet at the commencement date of the lease based upon the present value of lease payments over the lease term. When determining the lease term, the Company includes options to extend or to terminate the lease when it is reasonably certain that the Company will exercise that option. The Company uses the implicit interest rate when readily determinable and uses the Company’s incremental borrowing rate when the implicit rate is not readily determinable based upon the information available at the commencement date in determining the present value of the lease payments.

The lease payments used to determine the Company’s operating lease assets may include lease incentives, stated rent increases and escalation clauses linked to rates of inflation when determinable. In addition, the Company’s lease arrangements may contain lease and non-lease components. The Company combines lease and non-lease components, which are accounted for together as a single lease component. Variable lease payments, such as real

56

Table of Contents

EXICURE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share data)

estate taxes and facility maintenance costs that are allocated by the lessor to the lessee and are not based on an index or a rate, are excluded from the measurement of the lease liability.

Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Short-term leases, defined as leases that have a lease term of twelve months or less at the commencement date, are excluded from this treatment and are recognized on a straight-line basis over the term of the lease. Costs for variable lease payments that are not included in the lease liability are recognized as expense as incurred.

Research and development expense

Research and development expenses are charged to expense as incurred in performing research and development activities in accordance with ASC 730, Research and Development. The costs include employee‐related expenses including salaries, benefits, and stock‐based compensation expense, costs of funding research performed by third parties that conduct research and development and preclinical and clinical activities on the Company’s behalf, the cost of purchasing lab supplies and non‐capital equipment used in preclinical and clinical activities and in manufacturing preclinical and clinical study materials, consultant fees, facility costs including rent, depreciation and maintenance expenses, fees for acquiring and maintaining licenses under third party licensing agreements, including any sublicensing or success payments made to the Company’s licensors, and overhead and other expenses directly related to research and development operations. In accruing service fees, the Company estimates the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the Company’s estimate, the accrual or prepaid is adjusted accordingly. The Company defers and capitalizes non-refundable advance payments made by the Company for research and development activities until the related goods are received or the related services are performed. In circumstances where amounts have been paid in excess of costs incurred, the Company records a prepaid expense.

Income taxes

The Company recognizes deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of its assets and liabilities and the expected benefits of net operating loss carryforwards. The impact of changes in tax rates and laws on deferred taxes, if any, is applied during the years in which temporary differences are expected to be settled and is reflected in the financial statements in the period of enactment. The measurement of deferred tax assets is reduced, if necessary, if, based on weight of the evidence, it is more likely than not that some, or all, of the deferred tax assets will not be realized. At December 31, 2022 and 2021, the Company established a full valuation allowance against its deferred tax assets to an amount that is more likely than not to be realized.

Recent Accounting Pronouncements Not Yet Adopted

Financial Instruments - Credit Losses

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13). ASU 2016-13 is a new standard intended to improve reporting requirements specific to loans, receivables and other financial instruments. ASU 2016-13 requires that credit losses on financial assets measured at amortized cost be determined using an expected loss model, instead of the current incurred loss model, and requires that credit losses related to available-for-sale debt securities be recorded through an allowance for credit losses and limited to the amount by which carrying value exceeds fair value. ASU 2016-13 also requires enhanced disclosure of credit risk associated with financial assets. The effective date of ASU 2016-13 was deferred by ASU 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842)—Effective Dates to the annual period beginning after December 15, 2022 for companies that (i) meet the definition of an SEC filer and (ii) are eligible as “smaller reporting companies” as such term is defined by the SEC, with early adoption permitted. The Company expects that the adoption of ASU 2016-13 will not have a material impact to the Company’s consolidated financial statements.

3. Collaborative Research and License Agreements

Ipsen Collaboration Agreement

Summary of Agreement

On July 30, 2021 (the “Ipsen Effective Date”), the Company entered into a Collaboration, Option and License Agreement with Ipsen (the “Ipsen Collaboration Agreement”). Pursuant to the Ipsen Collaboration Agreement, the Company granted to Ipsen exclusive access and options to license SNA-based therapeutics arising from two collaboration programs related to the treatment of Huntington’s disease and Angelman syndrome (each, an “Ipsen Collaboration Program”), respectively. Each such license (obtained in connection with the exercise of an Ipsen Option, as defined and discussed further below) would grant to Ipsen exclusive, royalty-bearing, sublicensable, worldwide rights to develop, manufacture, use and commercialize such SNA therapeutics. Upon written notice to the Company, Ipsen may exercise its option during the corresponding collaboration program’s applicable option exercise period, (each, an “Ipsen Option Exercise Period”).

On December 12, 2022 (the “Ipsen Termination Agreement Effective Date”), the Company and Ipsen entered into a Mutual Termination Agreement (the “Ipsen Termination Agreement”), pursuant to which the parties mutually agreed to terminate the Ipsen Collaboration Agreement. Following such termination, the parties will jointly own R&D Term IP (as defined in the Ipsen Collaboration Agreement) and Patents Covering the R&D Term IP (as defined in the Ipsen Collaboration Agreement), with each party owning an equal, undivided interest in and to such R&D Term IP and patents. As a result of the termination of the Ipsen Collaboration Agreement, the Company regained the ability to independently develop medicines targeting Angelman syndrome and Huntington’s disease while Ipsen retains the right to re-enter into the collaboration with the Company in Huntington’s disease and Angelman’s syndrome.

As of the Ipsen Effective Date and through the Ipsen Termination Agreement Effective Date, the Company and Ipsen had agreed upon a development plan for each Ipsen Collaboration Program that describes the development activities and timelines required to advance each such Ipsen Collaboration Program through its first IND filing (each, an “Ipsen Development Plan”). The activities described in the Ipsen Development Plans were conducted under the supervision of the Ipsen Joint Steering Committee (the “Ipsen JSC”) consisting of three members from each of the Company and Ipsen. Under the terms of the Ipsen Collaboration Agreement, the Company was to use commercially reasonable efforts to conduct discovery and development in two collaboration programs for Huntington’s disease (the “HD Program”) and Angelman syndrome (the “AS Program”) (the “Ipsen Development Activities”) respectively. The Company was solely responsible for all costs and expenses of conducting each Ipsen Collaboration Program through the selection of SNA therapeutic candidates for further development (“Ipsen

Selection”), and Ipsen was responsible for all costs and expenses of all activities that were necessary to enable the first filing of an IND for each proposed product candidate. In the event that Ipsen exercised an option, Ipsen would have been responsible for further development from the license effective date and commercialization of the corresponding licensed product.
