Future Outlook

We anticipate submitting three investigational new drug (IND) applications with the U.S. Food and Drug Administration (FDA) by mid-2026, starting with HWK-007 for solid tumors (including NSCLC and ovarian cancer) in the fourth quarter of 2025, HWK-016 for cancers of female origin in the fourth quarter of 2025, and HWK-206 for cancers of neuroendocrine origin in mid-2026. We expect to increase investment in research and development related to the ADC Therapies and do not anticipate generating further revenue for the foreseeable future following the FYARRO divestiture. Management believes existing cash, cash equivalents, and short-term investments will fund planned operations into 2028.

Management Comments

• Management believes the Company's cash, cash equivalents and short-term investments will provide sufficient funds to enable the Company to meet its obligations for at least twelve months from the issuance of these financial statements.
• Based on our current plans, we believe our existing cash, cash equivalents and short-term investments will enable us to conduct our planned operations into 2028.
• We believe the resulting ADCs will be able to target cancers expressing these respective tumor markers precisely and deliver the potent, cytotoxic TOPO1 inhibitor at the site of cancer.
• Our track record of strong execution of novel drug formulation, research, clinical development, and commercialization in oncology, combined with our deep understanding of ADCs positions us to unlock the high potential of this differentiated ADC portfolio.
• We believe that our team is well positioned to execute on our strategy to develop and, if approved, commercialize the ADC Therapies and future pipeline assets to ultimately bring broad benefit to cancer patients worldwide.

Industry Context

The biopharmaceutical industry, particularly oncology and Antibody Drug Conjugates (ADCs), is characterized by rapidly advancing technologies, intense competition, and significant R&D investment. Whitehawk Therapeutics' pivot to a preclinical ADC pipeline aligns with a growing trend in targeted cancer therapies. The company faces competition from numerous established pharmaceutical and biotechnology companies with greater resources and experience in this field. The regulatory landscape is complex and evolving, with increasing scrutiny on drug pricing and data privacy, and potential impacts from geopolitical events and U.S.-China trade relations affecting supply chains. The company's reliance on WuXi Biologics and Hangzhou DAC (both in China) for its new ADC pipeline exposes it to specific geopolitical and regulatory risks, including the proposed BIOSECURE Act.

Comparison to Industry Standards

• The company is now a preclinical-stage biopharmaceutical company, which is a high-risk, high-reward segment of the industry. Most comparable companies at this stage would be focused on securing funding and advancing their lead candidates to IND.
• The in-licensing of three ADC programs from WuXi Biologics and Hangzhou DAC positions the company in a competitive and innovative area of oncology, similar to strategies pursued by larger players like Daiichi Sankyo, Gilead, and Pfizer who have significant ADC portfolios.
• The projected timeline for IND submissions (Q4 2025 for two, mid-2026 for one) is typical for preclinical assets, but successful progression through clinical trials is highly uncertain, with high failure rates common across the industry.
• The cash runway into 2028 is strong for a preclinical company, providing a solid foundation for initial development activities, which is a positive compared to many smaller biotechs that often have shorter runways.
• The divestiture of FYARRO, an approved product, to focus on an early-stage pipeline is a bold strategic move, contrasting with companies that typically seek to expand their commercialized portfolio. This indicates a high conviction in the new ADC platform.

Corporate Governance

Legal Proceedings

• No ongoing legal proceedings or claims where a liability has been recorded as of June 30, 2025, and December 31, 2024.
• Previously involved in an arbitration with EOC Pharma (Hong Kong) Limited, which concluded in September 2024 with the company found not liable for damages.

Stakeholder Impact

• Shareholders: Potential for significant long-term value creation if the new ADC pipeline is successful, but also high risk due to preclinical stage. Dilution from recent PIPE financing and potential future capital raises. Stock price volatility is a noted risk.
• Employees: Workforce reduction of 32% in August 2024 due to strategic shift. Share-based compensation plans are in place.
• Customers: No direct impact as the company is now preclinical and has divested its only commercial product.
• Suppliers/Partners: Increased reliance on WuXi Biologics and Hangzhou DAC for the new ADC pipeline, introducing supply chain and geopolitical risks.
• Creditors: Improved liquidity from divestiture and capital raise strengthens the company's ability to meet obligations.

Next Steps

• Submit Investigational New Drug (IND) application for HWK-007 (solid tumors, NSCLC, ovarian cancer) in Q4 2025.
• Submit IND application for HWK-016 (cancers of female origin) in Q4 2025.
• Submit IND application for HWK-206 (cancers of neuroendocrine origin) in mid-2026.
• Increase investment in research and development related to the ADC Therapies.
• Continue to evaluate the impact of the One Big Beautiful Bill Act on financial statements and disclosures (effective fiscal year 2025).
• Continue to evaluate the impact of the new tax law on financial position and results of operations.
• Continue to evaluate the impact of FDA guidance and other developments in the diagnostic space.

Key Dates

Recommendation

Whitehawk Therapeutics has undergone a significant strategic transformation, divesting its commercial asset (FYARRO) for a substantial cash inflow and pivoting entirely to a preclinical Antibody Drug Conjugate (ADC) pipeline. This move, while inherently high-risk due to the early stage of the new assets, is supported by a significantly strengthened balance sheet, with $177.2 million in cash and investments providing a runway into 2028. The company has a clear plan for advancing three ADC candidates to IND submissions by mid-2026, targeting high-potential cancer indications. The management team's stated experience in oncology drug development and commercialization, combined with the in-licensed advanced linker-payload technology, suggests a credible attempt to unlock value in a rapidly evolving and high-value segment of the biopharmaceutical market. For investors with a high-risk tolerance and a long-term investment horizon, the current valuation may present an attractive entry point given the potential upside of a successful ADC pipeline, despite the absence of near-term revenue and the inherent uncertainties of preclinical drug development. The recent capital raise and improved liquidity mitigate immediate financial concerns, allowing focus on pipeline execution.
