Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations 

You should read the following discussion and analysis of our financial condition and results of operations together with our condensed consolidated financial statements and the related notes included in Part I, Item 1 of this Quarterly Report on Form 10-Q (this “Quarterly Report”) and with the audited consolidated financial statements and the related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the Securities and Exchange Commission (the “SEC”) on February 28, 2025. Certain of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report, including information with respect to plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the section entitled “Risk Factors”, in Part I - Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025, as updated by the factors described under the heading “Risk Factors” in Part II - Item 1A of this Quarterly Report, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. You should carefully read the section entitled “Risk Factors” to gain an understanding of the important factors that could cause actual results to differ materially from our forward-looking statements. Please also see “Cautionary Note Regarding Forward-Looking Statements” below. The events and circumstances reflected in our forward-looking statements may not be achieved or may not occur, and actual results could differ materially from those described in or implied by the forward-looking statements contained in the following discussion and analysis. As a result of these risks, you should not place undue reliance on these forward-looking statements. We assume no obligation to revise or update any forward-looking statements for any reason, except as required by law.

Throughout this Quarterly Report, unless the context otherwise requires, the terms “Jasper,” “we,” “us” and “our” in this Quarterly Report refer to Jasper Therapeutics, Inc. and its consolidated subsidiary.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained in this Quarterly Report may constitute “forward-looking statements” for purposes of federal securities laws. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “will,” “would” and similar expressions (including the negative of any of the foregoing) may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

Forward-looking statements in this Quarterly Report may include, for example, but are not limited to, statements about:

These forward-looking statements are based on current expectations and beliefs concerning future developments and their potential effects. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described under the heading “Risk Factors” in Part I - Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025, as updated by the factors described under the heading “Risk Factors” in Part II - Item 1A of this Quarterly Report. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. Some of these risks and uncertainties may in the future be amplified, and there may be additional risks that we consider immaterial or which are unknown. It is not possible to predict or identify all such risks. Readers are cautioned not to place undue reliance on forward-looking statements because of the risks and uncertainties related to them and to the risk factors. We do not undertake any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

Overview 

We are a clinical-stage biotechnology company focused on developing therapeutics targeting mast cell driven diseases, including Chronic Spontaneous Urticaria (“CSU”), Chronic Inducible Urticaria (“CIndU”) and Asthma. We are evaluating additional indications in mast cell driven diseases for potential future development as well. We have also historically supported development programs in diseases where targeting diseased hemopoietic stem cells can provide benefits, such as stem cell transplant conditioning regimens.

Our lead product candidate, briquilimab, is a monoclonal antibody designed to block stem cell factor (“SCF”) from binding to and signaling through the CD117 (“c-Kit”) receptor on mast and stem cells. The SCF/c-Kit pathway is a survival signal for mast cells and we believe that blocking this pathway may lead to depletion of these cells throughout the body, including in the lungs and in the skin, which could lead to significant clinical benefit for patients with mast-cell driven diseases such as chronic urticarias. To that end, we are focusing on advancing a portfolio of clinical programs in mast cell driven diseases. Development highlights include:

We have also evaluated briquilimab as a one-time conditioning therapy for severe combined immunodeficiency (“SCID”) patients undergoing a second stem cell transplant for which we conducted a Phase 1/2 clinical trial.

We intend to become a fully integrated discovery, development and commercial company in the field of mast cell therapeutics. We are developing our product candidates to be used individually or, in some cases, in combination with other therapeutics. Our goal is to advance our product candidates through regulatory approval and bring them to the commercial market based on the data from our clinical trials and communications with regulatory agencies and payor communities. We expect to continue to broaden our pipeline with additional mast cell indications and next-generation products by leveraging our research organization.

We have an exclusive license agreement with Amgen Inc. (“Amgen”) for the development and commercialization of the briquilimab monoclonal antibody in all indications and territories worldwide. We also have an exclusive license agreement with Stanford University for the right to use briquilimab in the clearance of diseased stem cells prior to the transplantation of hematopoietic stem cells.

Since our inception, we have devoted substantially all of our resources to performing research and development, enabling manufacturing activities in support of our product development efforts, hiring personnel, acquiring and developing our technology and product candidates, performing business planning, establishing our intellectual property portfolio, raising capital and providing general and administrative support for these activities. We do not have any products approved for sale and have not generated any revenue from product sales. We expect to continue to incur significant and increasing expenses and substantial losses for the foreseeable future as we continue our development of and seek regulatory approvals for our product candidates and commercialize any approved products, seek to expand our product pipeline and invest in our organization. We expect to continue to incur increased expenses associated with operating as a public company, including significant legal, audit, accounting, regulatory, tax-related, director and officer insurance, investor relations and other expenses.

We have incurred significant losses and negative cash flows from operations since our inception. During the three months ended March 31, 2025 and 2024, we incurred net losses of $21.2 million and $13.7 million, respectively. We generated negative operating cash flows of $22.8 million and $15.7 million for the three months ended March 31, 2025 and 2024, respectively. As of March 31, 2025, we had an accumulated deficit of $262.1 million.

We had cash and cash equivalents of $48.8 million as of March 31, 2025. We expect to continue to incur substantial losses for the foreseeable future, and our transition to profitability will depend upon successful development, approval and commercialization of our product candidates and upon achievement of sufficient revenues to support our cost structure. We do not expect to generate any revenue from commercial product sales unless and until we successfully complete development and obtain regulatory approval for one or more of our product candidates. We may never achieve profitability, and unless we do and until then, we will need to continue to raise additional capital.

Our management plans to monitor expenses and raise additional capital through a combination of public and private equity, debt financings, strategic alliances, and licensing arrangements. Our ability to access capital when needed is not assured and, if capital is not available to us when, and in the amounts, needed, we may be required to significantly curtail, delay or discontinue one or more of our research or development programs or the commercialization of any product candidate, or be unable to expand our operations or otherwise capitalize on our business opportunities, as desired, which could materially harm our business, financial condition and results of operations.

We expect our expenses will increase substantially in connection with our ongoing and planned activities as we:

We do not currently own or operate any manufacturing facility. We rely on contract manufacturing organizations (“CMOs”) to produce our drug candidates in accordance with the FDA’s current good manufacturing practices (“cGMP”) regulations for use in our clinical studies. The manufacture of pharmaceuticals is subject to extensive cGMP regulations, which impose various procedural and documentation requirements and govern all areas of record keeping, production processes and controls, personnel and quality control. Under our license agreement with Amgen, we have received a substantial amount of drug product to support initiation of our planned clinical trials of briquilimab. In November 2019, we entered into development and manufacturing agreements with Lonza Sales AG (“Lonza”) relating to the manufacturing of briquilimab and product quality testing. The facility of Lonza in Slough, United Kingdom is responsible for production and testing of drug substance. The facility of Lonza in Stein, Switzerland is responsible for production and testing of drug product. Labelling, packaging and storage of finished drug product is provided by PCI Pharma Services, in San Diego, California. Our agreement with Lonza includes certain limitations on our ability to enter into supply arrangements with any other supplier without Lonza’s consent. In addition, Lonza has the right to increase the prices it charges us for certain supplies depending on a number of factors, some of which are outside of our control. In addition, given drug substance and drug product manufacturing and testing with Lonza currently occurs outside the United States, drug product imported into the United States for clinical or commercial use could be subject to significant tariffs in the current political environment.

We do not currently have sales and marketing infrastructure to support commercial launch of our product candidates, if approved. We may build such capabilities in North America prior to potential launch of briquilimab. Outside of North America, we may rely on licensing, co-sale and co-promotion agreements with strategic partners for the commercialization of our product candidates. If we build a commercial infrastructure to support marketing in North America, such commercial infrastructure could be expected to include a targeted sales force supported by sales management, internal sales support, an internal marketing group and distribution support. To develop the appropriate commercial infrastructure internally, we would have to invest financial and management resources, some of which would have to be deployed prior to any confirmation that briquilimab will be approved.

Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate revenue from the sale of our product candidates, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and may be forced to reduce our operations.

Components of Results of Operations

Operating Expenses

Research and Development

The largest component of our total operating expenses since our inception has been research and development activities, including the preclinical and clinical development of our product candidates. Research and development expenses consist primarily of compensation and benefits for research and development employees, including stock-based compensation; expenses incurred under agreements with clinical research organizations (“CROs”) and investigative sites that conduct preclinical and clinical studies; the costs of acquiring and manufacturing clinical study materials and other supplies; payments under licensing and research and development agreements; other outside services and consulting costs; and facilities, information technology and overhead expenses. Research and development costs are expensed as incurred.

External research and development costs include:

Internal research and development costs include:

We expect our research and development expenses to increase substantially for the foreseeable future as we advance our product candidates into and through preclinical studies and clinical trials, pursue regulatory approval of our product candidates and expand our pipeline of product candidates. The process of conducting the necessary preclinical and clinical research to obtain regulatory approval is costly and time-consuming. The actual probability of success for our product candidates may be affected by a variety of factors, including the safety and efficacy of our product candidates, early clinical data, investment in our clinical programs, competition, manufacturing capability and commercial viability. We may never succeed in achieving regulatory approval for any of our product candidates. As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our research and development projects or if, when and to what extent we will generate revenue from the commercialization and sale of our product candidates, if approved.

Our future research and development costs may vary significantly based on factors, such as:

General and Administrative

General and administrative expenses consist primarily of personnel costs and expenses, including salaries, employee benefits, and stock-based compensation for our executive and other administrative personnel; legal services, including relating to intellectual property and corporate matters; accounting, auditing, consulting and tax services; insurance; and facility and other allocated costs not otherwise included in research and development expenses. We expect our general and administrative expenses to increase substantially for the foreseeable future as we anticipate an increase in our personnel headcount to support expansion of research and development activities, as well as to support our operations generally. We also expect to continue to incur significant expenses associated with being a public company, including costs related to accounting, audit, legal, regulatory, and tax-related services associated with maintaining compliance with applicable Nasdaq and SEC requirements; additional director and officer insurance costs; and investor and public relations costs.

Other Income, Net

Other income, net includes foreign currency transactions gains and losses, interest income and change in the fair value of earnout liability. This financial instrument was classified as a liability in our condensed consolidated financial statements and was re-measured at each reporting period end. The earnout liability expired in September 2024 as the common stock price targets were not achieved prior to the expiration of the earnout period.

Results of Operations

Comparison of the Three Months Ended March 31, 2025 and 2024

The following table summarizes our results of operations for the three months ended March 31, 2025 and 2024 (in thousands, except percentages):

Research and Development Expenses

The following table summarizes our research and development expenses for the periods indicated (in thousands, except percentages):

Research and development expenses increased by $5.9 million, from $10.3 million for the three months ended March 31, 2024 to $16.2 million for the three months ended March 31, 2025.

Personnel-related costs, including employee payroll and related expenses, increased by $1.7 million, from $3.1 million for the three months ended March 31, 2024 to $4.8 million for the three months ended March 31, 2025, as a result of hiring additional employees in our research and development organization. Stock-based compensation expenses, included in personnel-related costs, increased by $0.2 million, from $0.4 million for the three months ended March 31, 2024 to $0.6 million for the three months ended March 31, 2025.

Facilities and overhead costs include common facilities, human resources and information technology related expenses allocated to research and development and increased primarily due to and expansion of leased facilities.

Program costs increased by $3.7 million, from $6.1 million for the three months ended March 31, 2024 to $9.8 million for the three months ended March 31, 2025. Clinical program expenses increased primarily due to an increase in costs by $1.4 million for the Asthma program that was initiated at the end of 2024 and an increase in costs for the CSU program from $2.1 million for the three months ended March 31, 2024 to $3.0 million for the three months ended March 31, 2025. CMO product development and manufacturing expenses unallocated by programs increased by $1.0 million from $1.1 million for the three months ended March 31, 2024 to $2.1 million for the three months ended March 31, 2025 due to an increase in manufacturing, packaging, and labeling costs to support clinical programs.

Our program costs for the three months ended March 31, 2025 and 2024 were as follows (in thousands):

General and Administrative Expenses

General and administrative expenses increased by $0.8 million, from $4.8 million for the three months ended March 31, 2024 to $5.6 million for the three months ended March 31, 2025. Employee payroll and related expenses increased by $0.7 million, from $2.6 million for the three months ended March 31, 2024 to $3.3 million for the three months ended March 31, 2025, as a result of continued hiring of administrative employees. Stock-based compensation expenses, included in employee payroll and related expenses, were $1.2 million and $0.8 million for the three months ended March 31, 2025 and 2024, respectively. Expenses related to professional consulting services increased by $0.2 million, from $1.8 million for the three months ended March 31, 2024 to $2.0 million for the three months ended March 31, 2025. Rent expenses increased by $0.1 million for the three months ended March 31, 2025 as compared to the three months ended March 31, 2024. Other expenses decreased by $0.2 million for the three months ended March 31, 2025 as compared to the three months ended March 31, 2024, primarily related to a decrease in allocation of overhead costs of $0.5 million, partially offset by an increase in office licenses and subscriptions expenses of $0.1 million, utilities expenses of $0.1 million and other general administrative expenses of $0.1 million.

Total Other Income, Net

Total other income, net decreased by $0.8 million, from $1.3 million net income for the three months ended March 31, 2024 to $0.6 million net income for the three months ended March 31, 2025. Interest income decreased by $0.8 million, from $1.4 million for the three months ended March 31, 2024 to $0.6 million for the three months ended March 31, 2025, primarily due to lower cash balances invested in money market funds. Changes in the earnout liability and foreign currency transactions gains and losses were insignificant.

Liquidity and Capital Resources

As of March 31, 2025, we had $48.8 million of cash and cash equivalents.

In order to assist in funding our future operations, including our planned clinical trials, on March 19, 2025, we filed a new universal shelf registration statement on Form S-3 (the “Shelf Registration Statement”) with the SEC, which was declared effective on March 26, 2025 and superseded our prior universal shelf registration statement. As of March 31, 2025, we can sell from time to time up to $300.0 million of common stock, preferred stock, debt securities, warrants, rights, units and depositary shares comprised of any combination of these securities, for our own account in one or more offerings under the Shelf Registration Statement. The terms of any offering under the Shelf Registration Statement will be established at the time of such offering and will be described in a prospectus supplement to the Shelf Registration Statement filed with the SEC prior to the completion of any such offering.

In February 2024, we closed an underwritten offering that was conducted off our prior universal shelf registration statement and issued 3,900,000 shares of common stock for net proceeds of $47.2 million.

As of March 31, 2025, $100.0 million remains allocated and available under the ATM Prospectus and $200.0 million remains available and unallocated under the Shelf Registration Statement. 

Future Funding Requirements

Our primary uses of cash are to fund our operations, which consist primarily of research and development expenditures related to our programs and, to a lesser extent, general and administrative expenditures. We anticipate that we will continue to incur significant expenses for the foreseeable future as we continue to advance our product candidates, expand our corporate infrastructure, operate as a public company, further our research and development initiatives for our product candidates, scale our laboratory and manufacturing operations, and incur marketing costs associated with potential commercialization. We are subject to all the risks typically related to the development of new drug candidates, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. We anticipate that we will need substantial additional funding in connection with our continuing operations.

We have incurred significant losses and negative cash flows from operations since our inception. As of March 31, 2025, we had an accumulated deficit of $262.1 million. Given our recurring losses from operations and negative cash flows, and based on our current operating plan, we have concluded that there is substantial doubt about our ability to continue as a going concern within one year from the date of filing of this Quarterly Report. We expect to finance our future cash needs through equity or debt financings, collaborations or a combination of these approaches. The sale of equity or convertible debt securities may result in dilution to our stockholders, and, in the case of preferred equity securities or convertible debt, those securities could provide for rights, preferences or privileges senior to those of our common stock. Debt financings may subject us to covenant limitations or restrictions on our ability to take specific actions, such as incurring additional debt or making capital expenditures. Our ability to raise additional funds may be adversely impacted by negative global economic conditions and any disruptions to and volatility in the credit and financial markets in the United States and worldwide or other factors. There can be no assurance that we will be successful in acquiring additional funding at levels sufficient to fund our operations or on terms favorable or acceptable to us. If we are unable to obtain adequate financing when needed or on terms favorable or acceptable to us, we may be forced to delay, reduce the scope of or eliminate one or more of our research and development programs.

Our future financing requirements will depend on many factors, including:

A change in the outcome of any of these or other variables could significantly change the costs and timing associated with the development of our product candidates. Furthermore, our operating plans may change in the future, and we may need additional funds to meet operational needs and capital requirements associated with such change.

Contractual Obligations and Commitments

We enter into contracts in the normal course of business with CROs for clinical trials, with CMOs for clinical supplies manufacturing and with other vendors for preclinical studies, supplies and other services and products for operating purposes. These contracts generally provide for termination on notice or may have a potential termination fee if a purchase order is cancelled within a specified time, and therefore are cancelable contracts. We do not expect any such contract terminations and did not have any non-cancellable obligations under these agreements as of March 31, 2025.

Leases

As of March 31, 2025, we leased approximately 25,900 square feet of space for our headquarters in Redwood City, California. The lease expires in August 2026. We have an option to extend the term for an additional five years to August 2031. In addition to base rent, we pay our share of operating expenses and taxes. As of March 31, 2025, our rent commitments under the lease agreement were $1.9 million within the next 12 months from March 31, 2025, and $0.8 million for the remainder of the lease term. 

Stanford License Agreements

In March 2021, we entered into an exclusive license agreement with Stanford (the “2021 Stanford License Agreement ”). In July 2023, we entered into an amendment to the 2021 Stanford License Agreement to modify certain milestones set forth thereunder. Pursuant to the 2021 Stanford License Agreement we are required to pay annual license maintenance fees, beginning on the first anniversary of the effective date of the agreement and ending upon the first commercial sale of a product, method, or service in the licensed field of use, as follows: $25,000 for each first and second year, $35,000 for each third and fourth year, and $50,000 at each anniversary thereafter ending upon the first commercial sale. We are also obligated to pay late-stage clinical development milestone payments and first commercial sales milestone payments of up to $9.0 million in total. We will also pay low single-digit royalties on net sales of licensed products. All products were in development as of March 31, 2025, and no such royalties were due as of such date and no milestones were achieved. 

In December 2024, we entered into a co-exclusive license agreement with Stanford (the “2024 Stanford License Agreement ”). Pursuant to the 2024 Stanford License Agreement, we are required to pay a license issuance fee of $75,000, which was paid in January 2025, and annual license maintenance fees, beginning on the first anniversary of the effective date of the agreement: $25,000 for each of the first through third years, $50,000 for each of the fourth through sixth years and $65,000 at each anniversary thereafter. We are also obligated to pay clinical development milestone payments of up to $1.3 million and sales milestone payments of up to $7.0 million in total. We will also pay low single-digit royalties on net sales of licensed products. All products are in development as of March 31, 2025, and no such royalties were due as of such date and no milestones were achieved.

Cash Flows

The following table summarizes our sources and uses of cash for the periods presented (in thousands):

Cash Flows from Operating Activities

Net cash used in operating activities was $22.8 million and $15.7 million for the three months ended March 31, 2025 and 2024, respectively.

Cash used in operating activities in the three months ended March 31, 2025 was primarily due to our net loss for the period of $21.2 million, adjusted by non-cash net loss of $2.3 million and a net change of $3.9 million in our net operating assets and liabilities. The non-cash amounts consisted of $1.8 million related to stock-based compensation expense, $0.3 million related to depreciation and amortization expense and $0.2 million of non-cash lease expense. The changes in our net operating assets and liabilities were primarily due to a decrease of $2.6 million in accrued expenses and other current liabilities, a decrease of $1.0 million in accounts payable, a decrease of $0.3 million in operating lease liability, and an increase of $0.2 million in prepaid expenses and other current assets, offset by a decrease of $0.3 million in other non-current assets.

Cash used in operating activities in the three months ended March 31, 2024 was primarily due to our net loss for the period of $13.7 million, adjusted by non-cash net loss of $1.6 million and a net change of $3.6 million in our net operating assets and liabilities. The non-cash amounts consisted of $1.2 million related to stock-based compensation expense, $0.3 million related to depreciation and amortization expense, and $0.1 million non-cash lease expense. The changes in our net operating assets and liabilities were primarily due to a decrease of $1.8 million in accounts payable, a decrease of $1.7 million in accrued expenses and other current liabilities, a decrease of $0.2 million in operating lease liability and an increase of $0.1 million in other non-current assets, offset by an increase of $0.2 million in prepaid expenses and other current assets.

Cash Flows from Investing Activities

Cash used in investing activities was less than $0.1 million for the three months ended March 31, 2025, consisting of sales of property and equipment.

Cash used in investing activities was less than $0.1 million for the three months ended March 31, 2024, which consisted of purchases of the computer and lab equipment.

Cash Flows from Financing Activities

Cash provided by financing activities for the three months ended March 31, 2024 was $47.3 million, which consisted primarily of net proceeds from the issuance and sale of shares of common stock in an underwritten public offering of $47.2 million and cash received from the exercise of stock options of $0.2 million. 

Critical Accounting Policies and Significant Judgments and Estimates

Our critical accounting policies are disclosed in Note 2 of the notes to the consolidated financial statements included in Part II - Item 8 of the Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025. Since the date of such financial statements, there have been no material changes to our significant accounting policies.

Recently Issued Accounting Pronouncements

See Note 2 to the condensed consolidated financial statements included in Part I - Item 1 of this Quarterly Report for more information regarding recently issued accounting pronouncements.

Smaller Reporting Company Status

Previously, we were an “emerging growth company,” as defined by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). The JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a U.S. Securities Act of 1933, as amended, registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. As of December 31, 2024, we ceased to be an emerging growth company.

We are now a “smaller reporting company,” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company until the last day of the fiscal year in which (i) the market value of our common stock held by non-affiliates exceeds $250 million as of the last business day of our second fiscal quarter, or (ii) our annual revenue exceeded $100 million during such completed fiscal year and the market value of our common stock held by non-affiliates exceeds $700 million as of the last business day of our second fiscal quarter.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes to our market risk during the three months ended March 31, 2025. For a discussion of our exposure to market risk, refer to the section titled “Quantitative and Qualitative Disclosures About Market Risk” included in Part II - Item 7A of the Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Our disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. As required by Rule 13a-15(b) or Rule 15d-15(b) promulgated by the SEC under the Exchange Act, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report. Based on the foregoing, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report at the reasonable assurance level.

Changes in Internal Controls

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are not currently party to, and none of our property is currently the subject of, any material legal proceedings.

Item 1A. Risk Factors

Our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025, in Part I –Item 1A, Risk Factors, describes important risk factors that could cause our business, financial condition, results of operations and growth prospects to differ materially from those indicated or suggested by forward-looking statements made in this Quarterly Report or presented elsewhere by management from time to time. Except as set forth below, there have been no material changes in the risk factors that appear in Part I - Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business. 

Risks Related to Our Financial Position and Need for Additional Capital

We have incurred significant net losses and negative operating cash flows since our inception. We expect to incur net losses for the foreseeable future and may never achieve or maintain profitability.

We are a clinical-stage biotechnology company dedicated to enabling cures through therapeutics targeting mast and hematopoietic stem cells and have a limited operating history. Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate effect or an acceptable safety profile, gain regulatory approval and become commercially viable. We have no products approved for commercial sale and have not generated any revenue from product sales to date, and we continue to incur significant research and development and other expenses related to our ongoing operations. As a result, we are not profitable and have incurred losses and negative operating cash flows in each period since our inception. For the three months ended March 31, 2025 and 2024, we reported net losses of $21.2 million and $13.7 million, respectively. For the three months ended March 31, 2025 and 2024, we reported negative operating cash flows of $22.8 million and $15.7 million, respectively. As of March 31, 2025, we had an accumulated deficit of $262.1 million. We have devoted all of our efforts to organizing and staffing our company, business and scientific planning, raising capital, acquiring and developing technology, identifying potential product candidates, undertaking research and preclinical studies of potential product candidates, developing manufacturing capabilities and evaluating a clinical path for our pipeline programs. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future, and we expect these losses to increase as we continue our research and development of, and seek regulatory approvals for, our product candidates.

The net losses we incur may fluctuate significantly from quarter to quarter. We anticipate that our expenses will increase substantially if and as we:

As a company, we have not completed clinical development of any product candidate and expect that it will be several years, if ever, before we have a product candidate ready for commercialization. To become and remain profitable, we must develop and, either directly or through collaborators, eventually commercialize a product or products with significant market potential. This will require us to be successful in a range of challenging activities, including identifying product candidates, completing preclinical testing and clinical trials of product candidates, obtaining marketing approval for these product candidates, manufacturing, marketing and selling those products for which we may obtain marketing approval and satisfying any post-marketing requirements.

We may never succeed in these activities and, even if we do, may never generate revenues that are significant or large enough to achieve profitability. Our product candidates and research programs are currently only in the early stages of development. Because of the numerous risks and uncertainties associated with developing product candidates, we are unable to predict the extent of any future losses or when we will become profitable, if at all. If we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of our company and could impair our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations. A decline in the value of our company could also cause you to lose all or part of your investment.

We will need substantial additional funding, which may not be available on acceptable terms, or at all. If we are unable to raise capital when needed, we would be forced to delay, reduce or eliminate our research and product development programs or future commercialization efforts.

We expect to spend substantial amounts of cash to conduct further research and development and preclinical testing and clinical trials of our product candidates, to seek regulatory approvals for our product candidates and to launch and commercialize any product candidates for which we receive regulatory approval. Furthermore, we expect to incur additional costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in order to maintain our continuing operations. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and product development programs or future commercialization efforts. As of March 31, 2025, our cash and cash equivalents were $48.8 million and we had an accumulated deficit of $262.1 million. We will need to raise additional financing to continue our products’ development for the foreseeable future, and will continue to need to do so until we become profitable. Our future financing requirements will depend on many factors, including:

Conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, even if we successfully develop product candidates and those are approved, we may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expect to be commercially available for several years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives.

We currently have an effective universal shelf registration statement on Form S-3, which we filed with the SEC on March 19, 2025, and which was declared effective on March 26, 2025 and will expire on March 26, 2028 (the “Shelf Registration Statement”). Pursuant to the Shelf Registration Statement, we may offer from time to time up to an aggregate of $300.0 million of securities, including any combination of common stock, preferred stock, debt securities, warrants, rights, units and depositary shares. On March 19, 2025, we entered into an Open Market Sale Agreement^SM with Jefferies LLC (the “Agent”), pursuant to which we may offer and sell through or to the Agent, as sales agent or principal, shares of common stock from time to time (the “ATM Offering”). On March 26, 2025, we filed with the SEC a prospectus under the Shelf Registration Statement in connection with the ATM Offering (the “ATM Prospectus”), pursuant to which we may offer and sell shares of common stock having an aggregate offering price of up to $100.0 million. No securities had been sold pursuant to the ATM Prospectus as of March 31, 2025.

As of May 8, 2025, $100.0 million remains allocated and available under the ATM Prospectus and approximately $200.0 million remains available and unallocated under the Shelf Registration Statement.

If we raise additional capital by issuing equity securities, the percentage ownership of our existing stockholders may be reduced, and accordingly these stockholders may experience substantial dilution. We may also issue equity securities that provide for rights, preferences and privileges senior to those of our common stock. Given our need for cash and that equity issuances are the most common type of fundraising for similarly situated companies, the risk of dilution is particularly significant for our stockholders.

Any additional fundraising efforts may divert our management from our day-to-day activities, which may adversely affect our ability to develop and commercialize product candidates. We cannot be certain that additional funding will be available on acceptable terms, or at all. We have no committed source of additional capital and, if we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of product candidates or other research and development initiatives. Our license agreements and any future collaboration agreements may also be terminated if we are unable to meet the payment or other obligations under the agreements. We could be required to seek collaborators for product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available or relinquish or license on unfavorable terms our rights to product candidates in markets where we otherwise would seek to pursue development or commercialization ourselves.

As a result of our history of losses and negative cash flows from operations, our management has performed an analysis and concluded that substantial doubt exists about our ability to continue as a going concern, and we will need to raise additional financing to continue our products’ development.

Our history of operating losses and negative cash flows from operations combined with our anticipated use of cash to fund operations raises substantial doubt about our ability to continue as a going concern beyond one year from the date of filing of this Quarterly Report. Our financial statements as of March 31, 2025 do not include any adjustments that might result from the outcome of this uncertainty. Based on our current operating plan, we will need to raise additional financing to continue our products’ development for the foreseeable future, and until we become profitable. Our future viability as an ongoing business is dependent on our ability to generate cash from our operating activities or to raise additional capital to finance our operations. We expect to finance our future cash needs through equity or debt financings, collaborations or a combination of these approaches. The sale of equity or convertible debt securities may result in dilution to our stockholders, and, in the case of preferred equity securities or convertible debt, those securities could provide for rights, preferences or privileges senior to those of our common stock. Debt financings may subject us to covenant limitations or restrictions on our ability to take specific actions, such as incurring additional debt or making capital expenditures. Our ability to raise additional funds may be adversely impacted by negative global economic conditions and any disruptions to and volatility in the credit and financial markets in the United States and worldwide or other factors. There can be no assurance that we will be successful in acquiring additional funding at levels sufficient to fund our operations or on terms favorable or acceptable to us. If we are unable to obtain adequate financing when needed or on terms favorable or acceptable to us, we may be forced to delay, reduce the scope of or eliminate one or more of our research and development programs.

The perception that we might be unable to continue as a going concern may also make it more difficult to obtain financing for the continuation of our operations on terms that are favorable to us, or at all, and could result in the loss of confidence by investors and employees. Our consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our consolidated financial statements, and it is likely that our investors will lose all or a part of their investment.

Risks Related to Discovery, Development, Manufacturing and Commercialization

Delays in the commencement or completion of clinical trials could result in increased costs to us and delay our ability to establish strategic collaborations.

Delays in the commencement or completion of clinical trials could significantly impact our drug development costs. We do not know whether planned clinical trials will begin on time or be completed on schedule, if at all. The commencement of clinical trials can be delayed for a variety of reasons, including, but not limited to, delays related to:

In addition, once a clinical trial has begun, it may be suspended or terminated by us, our collaborators, the institutional review boards or data safety monitoring boards charged with overseeing our clinical trials, the FDA, EMA or comparable foreign authorities due to a number of factors, including:

If we experience delays in the completion or termination of any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to commence product sales and generate product revenues from any of our product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs and slow down our product candidate development and approval process. Delays in completing our clinical trials could also allow our competitors to obtain marketing approval before we do or shorten the patent protection period during which we may have the exclusive right to commercialize our product candidates. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates.

If we experience delays or difficulties in the enrollment of patients in clinical trials, the cost of developing product candidates could increase and our receipt of necessary regulatory approvals could be delayed or prevented.

Patient enrollment is a significant factor in the timing of clinical trials. The timing of our clinical trials depends, in part, on the speed at which we can recruit patients to participate in our trials. We or our collaborators may not be able to continue clinical trials for briquilimab or any other product candidates we identify or develop if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA, the EMA or other analogous regulatory authorities outside the United States, or as needed to provide appropriate statistical power for a given trial. Patients may be unwilling to participate in our clinical trials because of negative publicity from adverse events related to the biotechnology competitive clinical trials for similar patient populations, clinical trials in competing products or for other reasons. As a result, the timeline for recruiting patients, conducting trials and obtaining regulatory approval of product candidates may be delayed.

Patient enrollment is also affected by other factors, including:

In addition, our clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas as our product candidates, and this competition will reduce the number and types of patients available to us because some patients who have opted to enroll in our trials may instead opt to enroll in a trial being conducted by a competitor. We may conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites.

Enrollment delays in our clinical trials may result in increased development costs for briquilimab or any other product candidates we may develop, which would cause the value of our company to decline and limit our ability to obtain additional financing. If we or our collaborators have difficulty enrolling a sufficient number of patients to conduct our clinical trials as planned, we may need to delay, limit or terminate ongoing or planned clinical trials, any of which would have an adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to Regulatory Review

Disruptions at the FDA, the SEC and other government agencies, including from government shutdowns, or funding changes, or other disruptions to these agencies’ operations, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products, to provide feedback on clinical trials and development programs, to meet with sponsors and to otherwise review regulatory submissions can be affected by a variety of factors, including government budget and funding levels, reductions in workforce, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. In the past, average review times at the agency have fluctuated, and this may continue in the future. In addition, government funding of other agencies on which our operations may rely is subject to the political process, which is inherently fluid and unpredictable. In addition, government shutdowns, if prolonged, could significantly impact the ability of government agencies upon which rely (such as the FDA and the SEC) to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

Disruptions at the FDA and other agencies may slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the past decade, the U.S. government has shut down several times, and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue to fund our operations.

Finally, with the change in presidential administrations in 2025, there is substantial uncertainty as to how, if at all, the new administration will seek to modify or revise the requirements and policies of the FDA and other regulatory agencies with jurisdiction over our product candidates. The impending uncertainty could present new challenges or potential opportunities as we navigate the clinical development and approval process for our product candidates. If we or our collaborators experience delays in obtaining approval or if we or they fail to obtain approval of our product candidates, the commercial prospects for our product candidates may be harmed and our ability to generate revenue will be materially impaired.

Risks Related to Employee Matters, Managing Growth and Information Technology

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

As of March 31, 2025, we had 60 full-time employees. As our development, manufacturing and commercialization plans and strategies develop and we continue our operations as a public company, we expect to need and are actively recruiting additional managerial, operational, sales, marketing, financial and other personnel. Future growth would impose significant added responsibilities on members of management, including:

Our future financial performance and our ability to commercialize our product candidates will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert a disproportionate amount of time to managing these growth activities.

We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors and consultants to provide certain services, including substantially all aspects of regulatory approval, clinical management and manufacturing. We cannot assure you that the services of independent organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval of our product candidates or otherwise advance our business. We cannot assure you that we will be able to manage our existing consultants or find other competent outside contractors and consultants on economically reasonable terms, or at all. If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, or if we are not able to effectively build out new facilities to accommodate this expansion, we may not be able to successfully implement the tasks necessary for further development and commercialization of our product candidates and, accordingly, may not achieve our research, development and commercialization goals.

Unstable market and economic conditions may have serious adverse consequences on our business and financial condition.

Our business, financial condition and results of operations could be adversely affected by general conditions in the global economy and in the global financial markets. A severe or prolonged economic downturn could result in a variety of risks to our business, including our ability to raise additional capital when needed on acceptable terms, if at all. A weak or declining economy could also strain our suppliers, service providers, manufacturers or other partners and there is a risk that one or more would not survive or be able to meet their commitments to us under such circumstances. There can be no assurances that deterioration in the credit and financial markets and confidence in economic conditions will not occur.

For example, U.S. debt ceiling and budget deficit concerns have increased the possibility of additional credit-rating downgrades and economic slowdowns, or a recession in the United States. Although U.S. lawmakers passed legislation to raise the federal debt ceiling on multiple occasions, including a suspension of the federal debt ceiling in June 2023, ratings agencies have lowered or threatened to lower the long-term sovereign credit rating on the United States. The impact of this or any further downgrades to the U.S. government’s sovereign credit rating or its perceived creditworthiness could adversely affect the U.S. and global financial markets and economic conditions. Absent further quantitative easing by the Federal Reserve, these developments could cause interest rates and borrowing costs to rise, which may negatively impact our results of operations or financial condition. Moreover, disagreement over the federal budget has caused the U.S. federal government to shut down for periods of time. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our business.

Furthermore, the new U.S. administration has substantially departed from prior U.S. government international trade policies and has commenced activities to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements and treaties with foreign countries. In addition, the new U.S. administration has initiated or is considering imposing tariffs on certain foreign goods. Related to this action, certain foreign governments, including China, have instituted or are considering imposing reciprocal tariffs on certain U.S. goods. It remains unclear what the new U.S. administration or foreign governments will or will not do with respect to tariffs or other international trade agreements and policies. A trade war or other governmental action related to tariffs or international trade agreements or policies has the potential to disrupt our research activities, affect our suppliers, increase the cost of materials purchased to manufacture our products, impact our ability to sell our products outside the United States or to sell our products outside the United States at competitive prices and/or to affect the United States or global economy or certain sectors thereof and, thus, could adversely impact our business and financial condition.

Risks Related to Ownership of Our Common Stock and Warrants

If our operations and performance do not meet the expectations of investors or securities analysts or for other reasons, the market price of our securities may decline, and the market price of our common stock may continue to be volatile.

Any of the factors listed below could have a negative impact on your investment in our securities, and our securities may trade at prices significantly below the price you paid for them. In such circumstances, the trading price of our securities may not recover and may experience a further decline.

Factors affecting the trading price of our securities may include:

In addition, the stock market in general, Nasdaq and pharmaceutical companies in particular have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. The trading price of our common stock is, and is likely to continue to be, volatile. For example, from January 2, 2024 to December 31, 2024, our closing stock price ranged from $6.63 to $30.00 per share. From January 2, 2025 to May 8, 2025, our closing stock price ranged from $3.47 to $21.09 per share. Broad market and industry factors may negatively affect the market price of our securities, regardless of our actual operating performance. As a result of this volatility, our stockholders may not be able to sell their common stock at or above the prices at which they purchased their shares. Moreover, in the past, stockholders have initiated class action lawsuits against pharmaceutical and biotechnology companies following periods of volatility in the market prices of these companies’ stock. Such litigation, if instituted against us, could cause us to incur substantial costs and divert management’s attention and resources from our business.

Insiders have substantial control over us, which could limit your ability to affect the outcome of key transactions, including a change of control.

As of March 31, 2025, our directors and executive officers and their affiliates beneficially owned approximately 20.6% of the outstanding shares of our common stock. As a result, these stockholders, if they act together, will be able to influence our management and affairs and all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, such as a merger or other sale of our company or our assets. This concentration of ownership may have the effect of delaying or preventing a change in control of our company or discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control, even if that change in control would benefit our other stockholders. This significant concentration of ownership may also adversely affect the trading price for our common stock because investors often perceive disadvantages in owning stock in companies with controlling stockholders.

Future sales, or the perception of future sales, by us or our stockholders in the public market, the issuance of rights to purchase our common stock, including pursuant to the 2024 Plan and the 2024 ESPP, and future exercises of registration rights could result in the additional dilution of the percentage ownership of our stockholders and cause the market price for our common stock to decline.

The sale of shares of our common stock, convertible securities or other equity securities in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. In addition, if we sell shares of our common stock, convertible securities or other equity securities, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to our existing stockholders, and new investors could gain rights, preferences, and privileges senior to the holders of our common stock.

Pursuant to the Jasper Therapeutics, Inc. 2024 Equity Incentive Plan (the “2024 Plan”), which became effective on June 6, 2024, we are authorized to grant equity awards to our employees, directors and consultants. In addition, pursuant to the Jasper Therapeutics, Inc. 2024 Employee Stock Purchase Plan (the “2024 ESPP”), which became effective on June 6, 2024, we are authorized to sell shares to our employees. As of March 31, 2025, 1,199,754 shares and 981,370 shares of our common stock are reserved for future issuance under the 2024 Plan and the 2024 ESPP, respectively.

On March 14, 2022, the Compensation Committee of our Board of Directors (the “Compensation Committee”) adopted the 2022 Inducement Equity Incentive Plan (the “2022 Inducement Plan”). On June 2, 2023, the Compensation Committee approved an amendment and restatement of our 2022 Inducement Plan to increase the maximum number of shares of our voting common stock available for grant by 250,000 shares of common stock to an aggregate of 550,000 shares of common stock. As of March 31, 2025, 50,574 shares of our common stock are available for future issuance under the 2022 Inducement Plan. The 2022 Inducement Plan has not been and will not be approved by our stockholders. Under the 2022 Inducement Plan, we can grant nonstatutory stock options, restricted stock awards, stock appreciation rights, restricted stock units, performance awards and other awards, but only to an individual, as a material inducement to such individual to enter into employment with us or an affiliate of ours, who (i) has not previously been an employee or director of ours or (ii) is rehired following a bona fide period of non-employment with us.

As of March 31, 2025, options to purchase an aggregate of 2,186,226 shares of our common stock and 20,000 performance-based restricted stock units were outstanding.

In the future, we may also issue our securities in connection with investments or acquisitions. The amount of shares of our common stock issued in connection with an investment or acquisition could constitute a material portion of our then-outstanding shares of our common stock. Any issuance of additional securities in connection with investments or acquisitions may result in additional dilution to our stockholders.
