Comparison of 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:

Research and development expenses

Research and development expenses for the three months ended March 31, 2025 increased $13.6 million compared to the three months ended March 31, 2024. The increase was primarily driven by an increase of $7.1 million in nomlabofusp manufacturing costs, an increase of $2.8 million in clinical costs primarily associated with the ongoing pediatric study which started and completed patient enrollment in the quarter ended March 31, 2025 and the start of our planned global Phase 3 study in the first quarter of 2025, an increase of $1.6 million in personnel expense due to increased headcount, and an increase of $1.2 million in consulting fees.

General and administrative expenses

General and administrative expenses for the three months ended March 31, 2025 increased $0.8 million compared to the three months ended March 31, 2024. The increase in general and administrative expenses was primarily driven by an increase of $0.7 million in personnel expense, an increase of $0.5 million in consulting fees primarily associated with commercial activities, partially offset by a decrease of $0.3 million in stock compensation expense.

Other income (expense), net

Other income (expense), net was $1.9 million income in the three months ended March 31, 2025 compared to $2.1 million income in the three months ended March 31, 2024. Other income consists primarily of interest income.

Liquidity and Capital Resources

Since our inception, we have not generated any revenue from any sources, including from product sales, and have incurred significant operating losses and negative cash flows from our operations. We have devoted substantially all of our resources to developing nomlabofusp, building our intellectual property portfolio, developing third-party manufacturing capabilities, business planning, capital raising, and providing general and administrative support for such operations.

Cash Flows

The following table summarizes our sources and uses of cash for each of the periods presented below:

Net cash used in operating activities

During the three months ended March 31, 2025, operating activities used $26.5 million of cash, resulting from our net loss of $29.3 million, adjusted for noncash expenses of $1.1 million and changes in our operating assets and liabilities resulting in a source of cash of $1.6 million. Our net loss was primarily attributed to research and development activities related to our nomlabofusp program and our general and administrative expenses as described above. Noncash expenses are primarily stock-based compensation expenses. The change in operating assets and liabilities was primarily due to an increase in accounts payable and decrease in both prepaid expense and accrued expenses.

During the three months ended March 31, 2024, operating activities used $10.4 million of cash, resulting from our net loss of $14.7 million, adjusted for noncash expenses of $1.6 million and changes in our operating assets and liabilities resulting in a source of cash of $2.7 million. Our net loss was primarily attributed to research and development activities related to our nomlabofusp program and our general and administrative expenses as described above. Noncash expenses are primarily stock-based compensation expenses. The change in operating assets and liabilities was primarily due to an increase in accounts payable and accrued expenses.

Net cash provided by (used in) investing activities

During the three months ended March 31, 2025, investing activities provided $14.4 million primarily from $67.0 million of cash provided by maturities of marketable securities, partially offset by the purchase of $52.3 million in marketable securities.

During the three months ended March 31, 2024, investing activities used $68.4 million of cash to purchase $84.9 million of marketable securities, partially offset by $16.5 million of cash provided by maturities of marketable securities.

Net cash provided by financing activities

During the three months ended March 31, 2025, there were no financing activities.

During the three months ended March 31, 2024, financing activities provided approximately $162.2 million of cash flows primarily from an offering of common stock.

Operating Capital Requirements

We have not yet commercialized any products and do not expect to generate revenue from the commercial sale of any products for several years, if at all.

We have to date incurred net losses. We incurred net losses of approximately $29.3 million and $14.7 million for the three months ended March 31, 2025 and 2024, respectively. As of March 31, 2025, we had an accumulated deficit of $298.4 million and cash, cash equivalents and marketable securities of $157.5 million, excluding restricted cash of $0.6 million.

Losses have resulted principally from costs incurred in connection with research and development activities, and general and administrative costs associated with the development of nomlabofusp and our operations. We expect to incur significant expenses and operating losses for the foreseeable future as we expect to continue to incur expenses in connection with our ongoing activities, if and as we:

•

continue to advance the development of nomlabofusp through additional clinical trials, including related manufacturing costs;

•

seek to identify and advance development of additional product candidates into clinical development and identify additional indications for our product candidates;

•

seek to obtain regulatory approvals for nomlabofusp and other potential product candidates;

•

identify, acquire or in-license other product candidates and technologies;

•

maintain, leverage and expand our intellectual property portfolio; and

•

expand our operational, financial, commercial and management systems and personnel, including personnel to support our clinical development and future commercialization efforts and our operations as a public company.

We anticipate that our current cash, cash equivalents and marketable securities will fund operations into the second quarter of 2026. If we encounter unexpected delays in our clinical trials or if there are other unanticipated changes to our operating plan from our current assumptions that negatively impact our operations, we may reduce expenditures in order to further extend our existing cash resources. Until we can generate substantial revenue, if ever, we expect to seek additional funding through a combination of public or private equity offerings, debt/royalty financings, collaborations, strategic alliances and licensing arrangements or other sources. The incurrence of indebtedness would result in increased fixed payment obligations and we may be required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, minimum cash balances, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates.

There can be no assurance that we will be able to raise sufficient additional capital on acceptable terms, if at all. If such additional financing is not available on satisfactory terms, or is not available in sufficient amounts, or we do not have sufficient authorized shares, we may be required to delay, limit, or eliminate the development of business opportunities and our ability to achieve our business objectives, our competitiveness, and our business, financial condition, and results of operations will be materially adversely affected. We could also be required to seek funds through arrangements with collaborative partners, strategic alliances or otherwise at an earlier stage than otherwise would be desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, operating results and prospects. In addition, geopolitical tensions including regional conflicts around the world, adverse macroeconomic events, including those due to inflationary pressures, rising interest rates, banking instability, monetary policy changes, changes in trade policies, including tariffs (including tariffs and trade protection measures that have been or may in the future be imposed by the U.S. or other countries), economic slowdowns or recessions, health epidemics, unforeseen emergencies and other outbreaks of communicable diseases could disrupt our operations, the operations of third parties on which we rely or the operations of regulatory agencies we interact with in the development of nomlabofusp and any other product candidates that we may develop which may reduce our ability to access capital, which could negatively affect our liquidity and ability to continue as a going concern.

If we are unable to obtain sufficient funding when needed and/or on acceptable terms, we may be required to significantly curtail, delay or discontinue one or more of our research and development programs, the manufacture of clinical and commercial supplies, product portfolio expansion and/or pre commercialization efforts, which could adversely affect our business prospects, or we may be unable to continue operations. Certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates.

Off-Balance Sheet Arrangements

During the periods presented we did not have, and we currently do not have, any off-balance sheet arrangements, as defined under applicable SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating financing transactions that are not required to be reflected on our balance sheets.
