Jasper Therapeutics, Inc.

Previous wording

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 six months ended June 30, 2025 and 2024, we reported net losses of $48.0 million and $28.3 million, respectively. For the six months ended June 30, 2025 and 2024, we reported negative operating cash flows of $38.3 million and $27.4 million, respectively. As of June 30, 2025, we had an accumulated deficit of $288.8 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.

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.

On July 8, 2025, we implemented a corporate reorganization to extend our cash runway, including a workforce reduction of approximately 50% of our employees at that time. In connection with this corporate reorganization, we refined our operating plan to focus on our briquilimab clinical development programs in chronic urticaria and halted enrollment in our Phase 1b/2a asthma study and halted our other clinical and preclinical programs. These changes to our business strategy and the reduction in workforce may yield unintended consequences and costs, such as the loss of institutional knowledge and expertise, attrition beyond our intended workforce reduction, a reduction in morale among our remaining employees, and the risk that the reorganization may not achieve the anticipated benefits, all of which may have an adverse effect on our development activities, ability to progress our product candidate development, and results of operations or financial condition. The total cost related to the workforce reduction is estimated to be approximately $1.9 million, all of which is cash-based expenditure related primarily to severance payments. We expect to recognize substantially all the charges related to the workforce reduction in the quarter ending September 30, 2025. These estimates are subject to a number of assumptions and actual results may differ.

The tax regimes we are subject to or operate under, including with respect to income and non-income taxes, are unsettled and may be subject to significant change. Changes in tax laws, regulations, or rulings, or changes in interpretations of existing laws and regulations, could materially adversely affect our company. For example, the Tax Cuts and JOBS Act, the Coronavirus Aid, Relief, and Economic Security Act, and the Inflation Reduction Act, or the IRA, enacted many significant changes to the U.S. tax laws. Future guidance from the Internal Revenue Service and other tax authorities with respect to such legislation may affect us, and certain aspects thereof could be repealed or modified in future legislation. For example, the IRA includes provisions that impact the U.S. federal income taxation of certain corporations, including imposing a 15% minimum tax on the book income of certain large corporations and a 1% excise tax on certain corporate stock repurchases that would be imposed on the corporation repurchasing such stock. Additionally, new income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could adversely affect our business operations and financial performance. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. For example, on July 4, 2025, new legislation was enacted in the United States which includes significant provisions, including, but not limited to, modifications of capitalization of research and development expenses and accelerated fixed asset depreciation. We are currently assessing the impact of the new legislation on our consolidated financial statements. It is also uncertain if and to what extent various states will conform to federal tax laws. In addition, many countries in Europe, as well as a number of other countries and organizations (including the Organization for Economic Cooperation and Development and the European Commission), have proposed, recommended, or (in the case of countries) enacted or otherwise become subject to changes to existing tax laws or new tax laws that could significantly increase our tax obligations in the countries where we do business or require us to change the manner in which we operate our business. Future tax reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges, and could increase our future tax expense.

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. For example, in July 2025, we reported that results from the 240mg Q8W and the 240mg followed by 180mg Q8W dose cohorts in our Phase 1b/2a BEACON study in CSU demonstrated an atypical absence of UAS7 reduction in 11 of the 13 patients enrolled, and as a result, we are investigating the results of those two cohorts. Among other factors being examined, we are assessing potential product lot variability in one lot of drug product first introduced into the BEACON study in those two cohorts, as all 10 patients dosed with drug supply from that lot failed to show reductions in their reported UAS7 scores. We expect to complete the investigation in the second half of 2025, and in the near-term have provided new clinical drug supply from a different lot for ongoing dosing of existing patients, and are enrolling an additional 10-12 new patients in aggregate across those two cohorts. . We are investigating the drug product lot in question and expect to have the results of that investigation in the second half of 2025. In addition, in July 2025, we halted enrollment in the ETESIAN study due to the fact that clinical material for the ETESIAN study was supplied from a drug product lot under investigation due to an atypical lack of efficacy noted in two of the cohorts in the BEACON study in which material from that drug product lot was also used. These and any other 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.

Based on the work conducted to date, we believe the anomalous efficacy results in these two cohorts do not appear to be related to drug substance (“DS”) or drug product (“DP”) manufacturing or distribution processes. With no evidence of DS or DP issues, the ongoing investigation is now focused on clinical site activity. We expect to complete the investigation in the fourth quarter of 2025, supported by a key opinion leader panel that will review findings and provide clinical and chemistry, manufacturing and controls recommendations for integration into the planned Phase 2b CSU study, and provided new clinical drug supply from a different lot for ongoing dosing of existing patients, and are enrolling an additional 10-12 new patients in aggregate across those two cohorts.

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.

Current wording

Beginning on October 1, 2025, the U.S. government shut down and remains shut down as of the date of this filing, during which time certain regulatory agencies, such as the FDA and the SEC, have furloughed certain employees and stopped certain activities. Additionally, on October 10, 2025, the U.S. government implemented substantial layoffs and workforce reductions in connection with the ongoing federal government shutdown, which has resulted in the suspension or delay of various government-funded programs. While we continue to monitor developments, there is no assurance that affected government employees or contractors will be reinstated and that government-funded programs will resume. 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, substantial changes in leadership and shifting policy priorities as a result of changes in the presidential administration and its appointees tasked to oversee the agency, 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.

Previous wording

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.

Current wording

Disruptions at the FDA and other agencies, including as a result of reductions in force, significant organizational changes, substantial leadership departures, and policy changes, may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. With the change in presidential administrations in 2025, there is substantial uncertainty as to how the current U.S. administration will continue to modify or revise the requirements and policies of the FDA and other regulatory agencies with jurisdiction over our product candidates. For example, the current U.S. administration has discussed several changes to the reach and oversight of the FDA, which could affect its relationship with the pharmaceutical industry, transparency in decision making and ultimately the cost and availability of prescription drugs. The impending uncertainty could present new challenges or potential opportunities as we navigate the clinical development and approval process for our product candidates. Additionally, over the last several years, including for 35 days beginning on December 22, 2018, the U.S. government has shut down several times, and certain regulatory agencies, such as the FDA , have had to furlough critical employees and stop certain critical activities. The current U.S. administration also recently announced plans to reduce the number of federal employees by establishing voluntary termination programs, by position eliminations or by involuntary terminations. If funding for the FDA is reduced, if the FDA workforce is reduced, or if the current government shutdown continues, 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. 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.

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.
