Notes to Unaudited Condensed Consolidated Financial Statements
Three-Month Periods Ended March 31, 2021 and 2020

1. Background and Basis of Presentation
Background: Athersys, Inc., including its consolidated subsidiaries (collectively, “we,” “us,” “our,” “Athersys,” and “Company”), is a biotechnology company focused in the field of regenerative medicine and operates in one business segment. Our operations consist of research, clinical development activities, manufacturing and manufacturing process development activities, and our most advanced program is in a pivotal Phase 3 clinical trial.
We have incurred losses since our inception in 1995 and had an accumulated deficit of $522.9 million at March 31, 2021, and we will not commence sales of our clinical product candidates until they receive regulatory approval for commercialization. We will require significant additional capital to continue our research and development programs, including progressing our clinical product candidates to potential commercialization and preparing for commercial-scale manufacturing and sales. At March 31, 2021, we had available cash and cash equivalents of $64.2 million. We believe that available proceeds from our existing equity facility, our ability to defer certain spending, and potential deferrals and delays in certain non-core programs, will enable us to meet our obligations as they come due at least for a period of twelve months from the date of the issuance of these unaudited condensed consolidated financial statements.
Importantly, we are approaching near-term milestones and clinical trial results, including the results of two clinical trials of our collaborator in Japan, HEALIOS K.K. (“Healios”), followed by the results of our pivotal Phase 3 clinical trial of MultiStem cell therapy for the treatment of ischemic stroke, or MASTERS-2, which we would expect to have a significant impact, favorable or unfavorable, on our ability to access capital from potential third-party commercial partners or the equity capital markets. Depending on the outcome of these clinical trials, we may accelerate, defer or stage the timing of certain programs. In the longer term, we will have to continue to generate additional capital to meet our needs until we would become cash flow positive as a result of the sales of our clinical products, if they are approved for marketing. Such capital would come from new and existing collaborations and their related license fees, milestones and potential royalties, the sale of equity securities from time to time including through our equity facility and grant-funding opportunities.
Healios Cooperation Agreement
On February 16, 2021, the Company, Healios and Dr. Hardy TS Kagimoto, the Chairman and Chief Executive Officer of Healios and a member of the Company’s board of directors (the “Board”), entered into a cooperation agreement (the “Cooperation Agreement”). The Cooperation Agreement provides for the parties' cooperation on certain commercial matters, including a commitment to work in good faith to finalize negotiations on all aspects of their supply, manufacturing, information provision and regulatory support relationship. Additionally, pursuant to the Cooperation Agreement, the parties agreed to seek to resolve issues over disputed payment obligations for certain manufacturing activities. We presently remain in dispute with Healios on some of these matters. A resolution of these matters may result in changes to our existing collaboration and licensing agreements with Healios. Despite our entry into the Cooperation Agreement, there can be no assurance that we will be able to resolve our disputes. If we are unable to resolve these matters, there could be an adverse impact to our commercialization and development plans and business.
The Cooperation Agreement also provides for, among related matters, the dismissal with prejudice of the complaint filed by Dr. Kagimoto against the Company seeking the inspection of the Company's books and records in the Court of Chancery of Delaware on November 21, 2020 (the “Section 220 Litigation”). Pursuant to the Cooperation Agreement, the Company reimbursed Healios and Dr. Kagimoto for reasonable out-of-pocket fees and expenses including legal expenses incurred in connection with the Section 220 Litigation, which were not to exceed $0.5 million in aggregate. A liability in the amount of $0.5 million was recorded in accounts payable to Healios on the condensed consolidated balance sheets at March 31, 2021 and December 31, 2020 and such amount was paid in April 2021.
Chief Executive Officer Separation Letter Agreement
Effective February 15, 2021, Dr. Gil Van Bokkelen resigned from his position as the Company’s Chief Executive Officer and Chairman of the Board. In connection with his resignation, the Company and Dr. Van Bokkelen entered into a separation letter agreement (the “Separation Letter”) entitling him to severance payments and benefits with an aggregate value of approximately $1.0 million payable in installments over an 18-month period, and providing for a total lump sum payment of approximately $0.2 million. At March 31, 2021, we recorded a liability in the amount of $0.9 million which represents the remaining installments payable to Dr. Van Bokkelen. The lump sum payment was made to Dr. Van Bokkelen in March 2021. The related expense is recorded in general and administrative expense on the unaudited condensed consolidated statement of operations and comprehensive loss.

Table of Contents
The terms of the Separation Letter also provide for the accelerated vesting of Dr. Van Bokkelen’s outstanding restricted stock units (“RSUs”) and the modification of his stock option awards by providing for accelerated vesting of his unvested stock options and the extension of time during which certain vested stock options can be exercised. In the first quarter of 2021, following the evaluation of the modification, we recorded stock compensation expense of approximately $1.4 million related to the accelerated vesting of Dr. Van Bokkelen’s stock options and $0.9 million related to the accelerated vesting of his RSUs.
Lease Agreement
On January 4, 2021, we entered into an agreement to lease approximately 214,000 square feet of warehouse and office space. The initial lease term is approximately ten years and includes five renewal options with terms of five years each. Base annual rent for the first year is approximately $1.3 million with 2.0% annual rent escalators. We expect to take possession of the building in the second quarter of 2021. We recorded no rent expense related to the lease during the first quarter of 2021.
Retention Program
In the first quarter of 2021, we entered into retention letter agreements (“Retention Agreements”) with our executive officers and certain other employees in leadership positions. Each Retention Agreement provides for, among other things, a cash retention bonus and a stock option award, each with vesting tied to continued employment. The cash retention bonuses generally represent a percentage of the employee’s annual compensation and generally vest in full if employed on May 1, 2022. The stock option awards generally vest one-third on May 1, 2022 with the remainder vesting on May 1, 2023, and include a provision for accelerated vesting upon termination without cause. The total cash retention bonus expected to be paid is approximately $2.0 million, which is being expensed over the vesting period. The total stock compensation expense related to the stock option awards is approximately $2.9 million and is being expensed over the vesting period. In April 2021, we expanded the retention program to all remaining employees of the Company, providing for a cash retention bonus with vesting also tied to continued employment through May 1, 2022. The total cash retention bonus expected to be paid on May 1, 2022 for these additional employees is approximately $0.6 million.
The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020. The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and Regulation S-X. Accordingly, since they are interim statements, the accompanying financial statements do not include all of the information and notes required by GAAP for complete financial statements. The accompanying financial statements reflect all adjustments, consisting of normal recurring adjustments and disclosures that are, in the opinion of management, necessary for a fair presentation of financial position and results of operations for the interim periods presented. Interim results are not necessarily indicative of results for a full year.
Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Our critical accounting policies, estimates and assumptions are described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” which is included in this Quarterly Report on Form 10-Q.
2. Recently Issued Accounting Standards
In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU is effective for fiscal years beginning after December 15, 2020. We adopted this ASU prospectively on January 1, 2021, and the adoption of the ASU did not have a material impact on our condensed consolidated financial statements and disclosures.
In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326). This ASU replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Subsequent to issuing ASU 2016-13, the FASB issued ASU 2019-10, Financial Instruments - Credit Losses (Topic 326): Effective Dates, delaying the effective date for smaller reporting companies until January 2023. We are currently evaluating the potential impact of adoption of this standard on our consolidated financial statements and disclosures, and we do not intend to early adopt.

3. Net Loss per Share
Basic and diluted net loss per share have been computed using the weighted-average number of shares of common stock outstanding during the period. We have outstanding stock-based awards that are not used in the calculation of diluted net loss per share because to do so would be anti-dilutive.
Stock-based awards of approximately 21,788,078 and 16,662,000 for the three-months ended March 31, 2021 and 2020, respectively, were excluded from the calculation of diluted net loss per share because their effects would be antidilutive.
4. Collaborative Arrangements and Revenue Recognition
Healios Collaboration
We have a licensing collaboration with Healios to primarily develop and commercialize our cell therapy technologies for certain disease indications in Japan, pursuant to which we received nonrefundable license fee payments and are entitled to royalties on net sales. We also have the right to receive development and commercial milestone payments from Healios, subject to certain potential credits that have been negotiated from time-to-time and are associated with modifications to the arrangement. Healios is responsible for the development and commercialization of the licensed products in the licensed territories, and we provide certain services to Healios for which we are paid.
Refer to Note 6 regarding Healios’ exercise of a warrant in March 2020 and its exercise of a right to participate in certain equity transactions in May 2020.
Healios Revenue Recognition
At the inception of the Healios arrangement and again each time that the arrangement is modified, all material performance obligations are identified, which currently include (i) licenses to our technology, (ii) product supply services and (iii) services to transfer technology to a contract manufacturer on Healios’ behalf. It was determined that these performance obligations are separate and distinct within the context of the contract. We determine the standalone selling price of each performance obligation and the related transaction price, taking into account variable consideration using the expected value or most likely amount method and reassessing our estimates each reporting period. We constrain, or reduce, the estimates of variable consideration if it is probable that a significant reversal of previously recognized revenue could occur throughout the life of the contract, and both the likelihood and magnitude of a potential reversal of revenue are taken into consideration.
At inception and upon each modification date, once the estimated transaction price is established, amounts are allocated to each separate performance obligation on a relative standalone selling price basis. These performance obligations include any remaining, undelivered elements at the time of modifications and any new elements from a modification to the arrangement if the conditions are not met for being treated as a separate agreement.
The remaining transaction price for the performance obligations that were not yet delivered is not significant at March 31, 2021. At March 31, 2021, the contract liability, included in Deferred revenue - Healios on the unaudited condensed consolidated balance sheet, is classified as a current liability since the rights to consideration are expected to be satisfied, in all material respects, within one year.
Advance from Healios
Certain clinical product supply services that were concluded in 2019 involved a cost-sharing arrangement, the proceeds from which may either (i) result in a reduction in the proceeds we receive from Healios upon the achievement of two potential milestones and an increase to a commercial milestone under the license agreement for stroke or (ii) be repaid to Healios at our election, as defined. The cost-sharing proceeds received are recognized in Advance from Healios on the unaudited condensed consolidated balance sheets until the earlier of the milestones being achieved or such amounts being repaid to Healios at our election, at which time, the culmination of the earnings process or the repayment will be complete.
5. Stock-based Compensation
Our 2019 Equity and Incentive Compensation Plan (the “EICP”) authorized at inception an aggregate of approximately 18,500,000 shares of common stock for awards to employees, directors and consultants. The EICP authorizes the issuance of stock-based compensation in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares and units, and other stock-based awards. Under the EICP, in the three-month period ended March 31, 2021, we granted 2,334,192 stock options.

Table of Contents
As of March 31, 2021, a total of 7,008,612 shares were available for issuance under our EICP, and stock-based awards to purchase 20,788,078 shares of common stock were outstanding under our current and former equity incentive plans, and inducement awards granted outside of our equity incentive plans to purchase 1,000,000 shares of common stock were outstanding. For the three-month periods ended March 31, 2021 and 2020, stock-based compensation expense was approximately $3.9 million and $1.3 million, respectively. At March 31, 2021, total unrecognized estimated compensation cost related to unvested stock-based awards was approximately $13.0 million, which is expected to be recognized by the end of 2025 using the straight-line method.
In June 2020, we modified stock option awards granted under the EICP and our prior equity plans for all then-current employees and directors by providing an extension to the period of time during which vested stock options can be exercised, first, for employees, following an employee’s voluntary termination of employment or the involuntary termination of the employee’s employment by the Company without cause (as defined with respect to the applicable options) and second, for directors, following a director’s death or voluntary termination of service with the Company, in each case following significant tenure with the Company. Upon modification, employees have post-employment exercise periods from three months up to a maximum of three years and directors have from eighteen months up to thirty months maximum, with the exercise periods increasing based on the applicable individual’s tenure. The modification was applied to all nonqualified stock option awards outstanding on the modification date and to those incentive stock options held by individuals who accepted the modification. Stock option awards issued post-modification include the extended exercise provisions as described in this paragraph. Following evaluation of the modification of the stock option awards, we recorded stock compensation expense of $1.2 million in the second quarter of 2020 for the incremental value of stock option awards vested prior to the modification date. The remaining incremental value of $0.5 million determined at the modification date, associated with the unvested stock option awards, is being recognized over the remaining vesting period of these modified stock option awards.
6. Stockholders’ Equity
Equity Purchase Agreement
We have had equity purchase agreements in place since 2011 with Aspire Capital Fund LLC (“Aspire Capital”) that provide us the ability to sell shares to Aspire Capital from time to time. Currently, we have an agreement with Aspire Capital that was entered into in November 2019 (the “2019 Equity Facility”) and includes Aspire Capital’s commitment to purchase up to an aggregate of $100.0 million of shares of our common stock over a defined timeframe. The terms of the 2019 Equity Facility are similar to the previous equity facilities with Aspire Capital, and we issued 350,000 shares of our common stock to Aspire Capital as a commitment fee in November 2019 and filed a registration statement for the resale of 31,000,000 shares of common stock in connection with the equity facility.
We sold 15,200,000 shares to Aspire Capital at an average price of $2.01 per share in the first quarter of 2021, generating proceeds of $30.5 million, and we sold 6,825,000 shares to Aspire Capital at an average price of $1.50 per share in the first quarter of 2020, generating proceeds of $10.2 million.
Public Offering
In April 2020, we completed an underwritten public offering of common stock, generating gross proceeds of approximately $57.6 million and net proceeds of approximately $53.7 million through the issuance of 25,587,500 shares of common stock at an offering price of $2.25 per share.
Healios Warrant
In March 2020, Healios elected to exercise its warrant in full, and we issued 4,000,000 shares of our common stock at an exercise price equal to the reference price of $1.76 per share, as defined in the warrant. Proceeds of approximately $7.0 million were received in April 2020 in accordance with the terms of the warrant.
Healios Investor Rights Agreement
In March 2018, we entered into an investor rights agreement (the “Investor Rights Agreement”) with Healios that governs certain of our and Healios’ rights relating to its ownership of our common stock. Under the Investor Rights Agreement, Healios is permitted to participate in certain equity issuances as a means to maintain its proportionate ownership of our common stock as of the time of such issuance. In May 2020, we entered into a purchase agreement with Healios, providing for Healios to purchase shares of our common stock in connection with certain equity issuances to Aspire Capital. Healios purchased 310,526 shares of our common stock at $1.72 per share for an aggregate purchase price of $0.5 million, in accordance with the terms of the Investor Rights Agreement.

7. Income Taxes
We have United States (“U.S.”) federal net operating loss and research and development tax credit carryforwards, as well as state and city net operating loss carryforwards, which may be used to reduce future taxable income and tax liabilities. We also have foreign net operating loss and tax credit carryforwards, and the foreign net operating loss carryforwards do not expire. All of our deferred tax assets have been fully offset by a valuation allowance due to our cumulative losses. The carrying value of our deferred tax assets and liabilities is determined by the enacted U.S. corporate income tax rate. Consequently, any changes in the U.S. corporate income tax rate impacts the carrying value of our deferred tax assets and liabilities. Also, there are significant limitations on our ability to utilize our net operating loss and tax credit carryforwards under Section 382 of the Internal Revenue Code of 1986, as amended.
Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations.
This discussion and analysis should be read in conjunction with our unaudited financial statements and notes thereto included in this Quarterly Report on Form 10-Q and the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020. Operating results are not necessarily indicative of results that may occur in future periods.
Overview and Recent Developments
We are a biotechnology company that is focused primarily in the field of regenerative medicine. Our MultiStem cell therapy, a patented and proprietary allogeneic stem cell product candidate, is our lead platform product in clinical development in several therapeutic and geographic areas. Our current clinical development programs are focused on treating neurological conditions, inflammatory and immune disorders, certain pulmonary conditions, cardiovascular disease and other conditions where the current standard of care is limited or inadequate for many patients, particularly in the critical care segment.
The COVID-19 pandemic has adversely impacted operations at certain existing and potential future clinical sites involved in our ongoing clinical studies. It is possible that the COVID-19 pandemic could adversely affect our business, results of operations, financial condition or liquidity in the future. For example, it could impact the timing and enrollment of our or our collaborator’s planned or ongoing clinical trials, delaying clinical site initiation, regulatory review and the potential receipt of regulatory approvals, payment of milestones under our license agreements and commercialization of one or more of our product candidates, if approved. The COVID-19 pandemic could also disrupt the production capabilities of our contract manufacturing partners and materially and adversely impact our MultiStem trial supply chain. Further, the outbreak of COVID-19 has heightened the risk that a significant portion of our workforce may suffer illness or otherwise be unable to work. The impact of the COVID-19 pandemic is fluid and continues to evolve, and therefore, we cannot currently predict the extent to which our business, clinical trials, results of operations, financial condition or liquidity will ultimately be impacted.
Current Programs
Our MultiStem cell therapy product development programs in the clinical development stage include the following:
Ischemic Stroke: We are conducting a pivotal Phase 3 clinical trial of MultiStem cell therapy for the treatment of ischemic stroke, referred to as MASTERS-2. Our MASTERS-2 clinical trial is a randomized, double-blind, placebo-controlled clinical trial designed to enroll 300 patients in North America, Europe and certain other international locations, who have suffered moderate to moderate-severe ischemic stroke. We initiated the study with a limited number of high-enrolling sites and are bringing on additional sites over time in line with clinical product supply and clinical operations objectives. Enrollment has been impacted at some clinical sites due to operational restrictions at the hospital sites, including hospital staff redeployment in response to the COVID-19 pandemic, and supply constraints, which have hampered the initiation of new sites. Given the recent headwinds, we hope to complete enrollment of the trial in 2022. The MASTERS-2 study has received several regulatory designations including Special Protocol Assessment, or SPA, Fast Track and Regenerative Medicine Advanced Therapy, or RMAT, from the United States Food and Drug Administration, or FDA, as well as a Final Scientific Advice positive opinion from the European Medicines Agency, or EMA.
In addition, HEALIOS K.K., or Healios, has an ongoing clinical trial, TREASURE, evaluating the safety and efficacy of administration of MultiStem cell therapy for the treatment of ischemic stroke in Japan. TREASURE will be evaluated under the progressive regulatory framework for regenerative medicine therapies in Japan. Under the new framework, Healios’ ischemic stroke program has been awarded the Sakigake designation by the Pharmaceuticals and Medical Devices Agency, or PMDA, which is designed to expedite regulatory review and approval and is analogous to Fast Track designation from the FDA. Healios has reported that current enrollment of patients in the clinical trial
12

Table of Contents
exceeds 90%. We look forward to the completion of both the MASTERS-2 and TREASURE trials and using the accelerated pathways to review and approval afforded to us by the regulators in the United States, Europe and Japan.
ARDS: In January 2019 and January 2020, we announced summary results and one-year follow up results, respectively, from our exploratory clinical study of the intravenous administration of MultiStem cell therapy to treat patients who are suffering from acute respiratory distress syndrome, or ARDS. The study results continue to demonstrate a predictable and favorable tolerability profile. Importantly, there were lower mortality and a greater number of ventilator-free and ICU-free days in the MultiStem-treated patient group compared to the placebo group. Average quality-of-life outcomes were higher in the MultiStem group compared to placebo through one year. In April 2020, the FDA authorized the initiation of a Phase 2/3 pivotal study to assess the safety and efficacy of MultiStem therapy in subjects with moderate to severe ARDS induced by COVID-19, or the MACOVIA study, and the first patients were enrolled in May 2020. In September 2020, MultiStem cell therapy received RMAT designation for the ARDS program. The MACOVIA study features an open-label lead-in followed by a double-blinded, randomized, placebo-controlled Phase 2/3 portion, and the study is presently designed to enroll up to approximately 400 patients at leading pulmonary critical care centers throughout the United States. However, the scope and timing of our MACOVIA study may be adjusted to reflect rapidly changing standards of care for COVID-induced ARDS patients, and depending on regulatory discussions and funding sources. Healios has also been conducting a clinical trial in Japan for patients with pneumonia-induced ARDS, which is referred to as the ONE-BRIDGE study. Healios recently announced they have completed enrollment in this study.
Trauma: In April 2020, the FDA authorized the initiation of a Phase 2 clinical trial evaluating MultiStem cell therapy for the early treatment of traumatic injuries and the subsequent complications that result following severe trauma. The trial is being conducted by The University of Texas Health Science Center at Houston, or UTHealth, at the Memorial Hermann-Texas Medical Center in Houston, Texas, one of the busiest Level 1 trauma centers in the United States. This study is being supported under a grant awarded to the McGovern Medical School at UTHealth from the Medical Technology Enterprise Consortium, and the Memorial Hermann Foundation is providing additional funding. We are providing the investigational clinical product for the trial as well as regulatory and operational support. The COVID-19 pandemic has impacted the pace of activity for the study since the trauma center also attends to COVID-19 patients, and the site announced that enrollment commenced in December 2020.
While the MultiStem product platform continues to advance, we are engaged in process development initiatives intended to increase manufacturing scale, reduce production costs and enhance process controls, yield and product quality, among other things. These initiatives are being conducted both internally and outsourced to select contractors, and the related investments are meant to enable us to meet potential commercial demand in the event of eventual regulatory approval. Until such time as we are able to manufacture products ourselves in accordance with good manufacturing practices, we will continue to rely on third-party manufacturers to make our MultiStem product for clinical trials and eventual commercial sales. These third parties may not deliver sufficient quantities of our MultiStem product, manufacture MultiStem product in accordance with specifications, or comply with applicable government regulations. From time to time, such third-party manufacturers, or their material suppliers, may experience production delays, stoppages or interruptions in supply, which may affect the initiation, execution and timing of completion of our and our partners' clinical trials or potential commercial activities.
We have a collaboration with Healios for MultiStem cell therapy to treat ischemic stroke and ARDS in Japan, and we provide product supply and manufacturing services to Healios. In the event that we fail to perform our responsibilities to supply clinical trial product to Healios, then under certain circumstances, we may be required to grant Healios a license to make the product solely for use in its licensed fields and territories.
Financial
In April 2020, we completed an underwritten public offering of common stock, generating gross proceeds of approximately $57.6 million and net proceeds of approximately $53.7 million through the issuance of 25,587,500 shares of common stock at an offering price of $2.25 per share.
In connection with an equity investment in us made by Healios in March 2018, Healios received a warrant to purchase shares of our common stock. In March 2020, Healios elected to exercise its warrant in full, and we issued 4,000,000 shares of our common stock at an exercise price equal to the reference price of $1.76 per share, as defined in the warrant. The proceeds of approximately $7.0 million were received in April 2020 in accordance with the terms of the warrant.
We have had equity purchase agreements in place since 2011 with Aspire Capital Fund LLC, or Aspire Capital, that provide us the ability to sell shares to Aspire Capital from time to time. Currently, we have an agreement with Aspire Capital that was entered into in November 2019 and includes Aspire Capital’s commitment to purchase up to an aggregate of $100.0 million of shares of our common stock over a defined timeframe. During the quarter ended March 31, 2021, we sold 15,200,000 shares of
13

Table of Contents
our common stock to Aspire Capital at an average price of $2.01 per share. During the quarter ended March 31, 2020, we sold 6,825,000 shares of common stock to Aspire Capital at an average price of $1.50 per share.
We have entered into a series of agreements with Healios, our collaborator in Japan. Under the collaboration that began in 2016, Healios is responsible for the development and commercialization of the MultiStem product for the licensed fields in the licensed territories, and we provide services to Healios for which we are compensated. Each license agreement with Healios has defined economic terms, and we may receive success-based milestone payments, some of which may be subject to credits. While there is no assurance that we will receive milestone proceeds under the Healios collaboration, any milestone payment we receive is non-refundable and non-creditable towards future royalties or any other payment due from Healios. Also, we are entitled to receive tiered royalties on net product sales, as defined in the license agreements.
In March 2018, we entered into an investor rights agreement, or the Investor Rights Agreement, with Healios, which governs certain of our and Healios’ rights relating to Healios’ ownership of our common stock. Under the Investor Rights Agreement, Healios is permitted to participate in certain equity issuances as a means to maintain its proportional ownership of our common stock as of the time of issuance. In May 2020, we entered into a purchase agreement with Healios providing for Healios to purchase shares of our common stock in connection with certain equity issuances to Aspire Capital. In May 2020, we sold to Healios 310,526 shares of our common stock at $1.72 per share for an aggregate purchase price of $534,105, in accordance with the terms of the Investor Rights Agreement.
Results of Operations
Since our inception, our revenues have consisted of license fees, contract revenues, royalties and milestone payments from our collaborators, and grant proceeds. We have not derived revenue from the commercial sale of our therapeutic product candidates to date since we are in clinical development. Research and development expenses consist primarily of external clinical and preclinical study fees, manufacturing and process development costs, salaries and related personnel costs, legal expenses resulting from intellectual property prosecution processes, facility costs, and laboratory supply and reagent costs. We expense research and development costs as they are incurred. We expect to continue to make significant investments in research and development to enhance our technologies, advance clinical trials of our product candidates, expand our regulatory affairs and product development capabilities, conduct preclinical studies of our product, manufacture our product candidates and prepare for potential commercialization of our MultiStem cell therapy product. General and administrative expenses consist primarily of salaries and related personnel costs, professional fees and other corporate expenses. We expect to continue to incur substantial losses through at least the next several years.
Three Months Ended March 31, 2021 and 2020
Revenues. There were no revenues for the three months ended March 31, 2021 or for the three months ended March 31, 2020. Our collaboration revenues fluctuate from period-to-period based on new licenses conferred and the delivery of goods and services under our arrangement with Healios. We expect our collaboration revenues to vary over time as we contract with Healios to perform manufacturing services and as we potentially enter into new collaborations.
Research and Development Expenses. Research and development expenses increased to $17.5 million for the three months ended March 31, 2021 from $12.1 million for the comparable period in 2020. The $5.4 million increase is associated with increases in clinical trial and manufacturing process development costs of $4.3 million, personnel costs of $0.7 million and stock compensation costs of $0.4 million. Our clinical development, clinical manufacturing and manufacturing process development expenses vary over time based on the timing and stage of clinical trials underway, manufacturing campaigns for clinical trials and manufacturing process development projects, and we expect our annual 2021 research and development expenses to increase compared to 2020. These variations in activity level may also impact our accounts payable, accrued expenses, prepaid expenses and deposits balances from period to period. Other than external expenses for our clinical and preclinical programs, we generally do not track our research expenses by project; rather, we track such expenses by the type of cost incurred.
General and Administrative Expenses. General and administrative expenses increased to $8.8 million for the three months ended March 31, 2021 from $3.5 million in the comparable period in 2020. The $5.3 million increase was primarily related to legal expenses incurred in connection with the complaint filed by Dr. Kagimoto against the Company, its settlement, and the expenses associated with Dr. Van Bokkelen’s resignation and his separation letter agreement, including $2.3 million of non-cash stock compensation expense. We expect our annual 2021 general and administrative expenses to increase compared to 2020.

Table of Contents
Depreciation. Depreciation expense was consistent at $0.2 million for the three months ended March 31, 2021 and March 31, 2020. We expect that our annual depreciation will increase in 2021 compared to 2020.
Other Income, net. Other income, net, generally includes net foreign currency gains and losses, and net interest income and expense.
Liquidity and Capital Resources
Our sources of liquidity include our cash balances. At March 31, 2021, we had $64.2 million in cash and cash equivalents. We have primarily financed our operations through business collaborations, grant funding and equity financings. The COVID-19 pandemic could negatively impact our ability to access financing sources on the same or reasonably similar terms as were available to us before the pandemic. We conduct all of our operations through our subsidiary, ABT Holding Company. Consequently, our ability to fund our operations depends on ABT Holding Company’s financial condition and its ability to make dividend payments or other cash distributions to us. There are no restrictions such as government regulations or material contractual arrangements that restrict the ability of ABT Holding Company to make dividend and other payments to us.
We incurred losses since inception of operations in 1995 and had an accumulated deficit of $522.9 million at March 31, 2021. Our losses have resulted principally from costs incurred in research and development, clinical and preclinical product development, acquisition and licensing costs, and general and administrative costs associated with our operations. We use all of our sources of capital to develop our technologies, discover and develop therapeutic product candidates and develop business collaborations, and we may use our sources of capital to acquire certain technologies and assets.
We are entitled to receive potential milestones payments, subject to certain credits, and royalties from Healios under our licensed programs. We also receive payments from Healios for clinical product supply and other manufacturing-related services. Certain proceeds from Healios may be used by Healios to offset milestone payments that may become due in the future.
In April 2020, we completed an underwritten public offering of common stock, generating gross proceeds of approximately $57.6 million and net proceeds of approximately $53.7 million through the issuance of 25,587,500 shares of common stock at an offering price of $2.25 per share.
In March 2020, Healios elected to exercise a warrant in full, and we issued 4,000,000 shares of our common stock at an exercise price equal to the reference price of $1.76 per share, in accordance with the terms of the warrant. The proceeds of approximately $7.0 million were received in April 2020.
We have had equity purchase agreements in place since 2011 with Aspire Capital that provide us the ability to sell shares to Aspire Capital from time to time. Currently, we have an agreement with Aspire Capital that was entered into in November 2019 and includes Aspire Capital’s commitment to purchase up to an aggregate of $100.0 million of shares of our common stock over a defined timeframe. During the quarter ended March 31, 2021, we sold 15,200,000 shares of common stock to Aspire Capital at an average price of $2.01 per share. During the quarter ended March 31, 2020, we sold 6,825,000 shares of common stock to Aspire Capital at an average price of $1.50 per share.
We will require substantial additional funding in order to continue our research and product development programs, including clinical trials of our product candidates and process development and manufacturing projects, and to prepare for possible approval and commercial activities. We intend to generate additional funding to meet our needs through business development and other transactions, payments resulting from achievement of milestones under our collaborator agreements, grant-funding activities and other activities. At March 31, 2021, we had available cash and cash equivalents of $64.2 million. We intend to meet our short-term liquidity needs with available cash and the use of our equity facility. Over the longer term, we will continue to make use of available cash and may raise capital from time to time through our equity facility, subject to any volume and price limitations, and equity offerings. We may also manage our cash by deferring certain discretionary costs and staging certain development costs to extend our operational runway, as needed. Over time, we may consider borrowing from financing institutions.
Our capital requirements depend on a number of factors, including progress in our clinical development programs, our clinical and preclinical pipeline of additional product opportunities and their stage of development, additional external costs, such as payments to contract research organizations and contract manufacturing organizations, additional personnel costs and the costs of filing and prosecuting patent applications and enforcing patent claims. Furthermore, delays in product supply for our and Healios’ clinical trials may impact the timing and cost of such studies. The availability of funds impacts our ability to advance multiple clinical programs concurrently, and any shortfall in funding could result in our having to delay or curtail research and development efforts. Further, these requirements may change at any time due to technological advances, business development activity or competition from other companies. We cannot assure you that adequate funding will be available to us or, if available, that it will be available on acceptable terms.

We expect to continue to incur substantial losses through at least the next several years and may incur losses in subsequent periods. The amount and timing of our future losses are highly uncertain. Our ability to achieve and thereafter sustain profitability will be dependent upon, among other things, successfully developing, commercializing and obtaining regulatory approval or clearances for our technologies and products resulting from these technologies.
Cash Flow Analysis
Net cash used in operating activities was $17.1 million for the three months ended March 31, 2021 compared to $12.1 million for the three months ended March 31, 2020. Net cash used in operating activities may fluctuate significantly on a quarter-to-quarter basis, as it has over the past several years, primarily due to the receipt of fees from our collaborators and payment of clinical trial costs, such as clinical manufacturing campaigns, contract research organization costs and manufacturing process development projects. These variations in activity level may also impact our accounts payable, accrued expenses, prepaid expenses and deposits balances from period to period.
Net cash used in investing activities was $0.1 million and $0.3 million for the three months ended March 31, 2021 and 2020, respectively. The fluctuations over the periods were due to the timing of equipment purchases primarily for our manufacturing process development activities.
Financing activities provided cash of $29.9 million and $10.1 million for the three months ended March 31, 2021 and 2020, respectively, primarily from the issuance of common stock to Aspire Capital under our equity purchase agreements. Also included in financing activities for the three months ended March 31, 2021 and March 31, 2020 are shares retained for withholding tax payments on stock-based awards.
Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements.
Critical Accounting Policies and Management Estimates
The SEC defines critical accounting policies as those that are, in management’s view, important to the portrayal of our financial condition and results of operations and demanding of management’s judgment. Our discussion and analysis of financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates on experience and on various assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from those estimates. A description of these accounting policies and estimates is included in Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2020. There have been no material changes in our accounting policies and estimates as described in our Annual Report on Form 10-K for the year ended December 31, 2020.
For additional information regarding our accounting policies, see Note B to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2020.

Aspire Capital Equity Purchase Agreement
During the quarter ended March 31, 2021, we sold 15,200,000 shares of common stock to Aspire Capital under our equity purchase agreement, generating proceeds of $30.5 million. Each issuance of these unregistered shares qualifies as an exempt transaction pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). Each issuance qualified for exemption under Section 4(a)(2) of the Securities Act because it did not involve a public offering. Each offering was not a public offering due to the number of persons involved, the manner of the issuance and the number of securities issued. In addition, Aspire Capital had the necessary investment intent.
