Future Outlook

TuHURA Biosciences anticipates continued significant operating losses as it advances product candidates through preclinical and clinical development and seeks regulatory approvals. The company expects to require substantial additional funding beyond early Q3 2026 to support its operations and growth strategy, which will likely be financed through equity offerings, debt, collaborations, or licensing arrangements. Future clinical development costs are highly unpredictable and depend on trial outcomes, regulatory developments, and commercial potential. The company plans to discuss TBS-2025 development with the FDA in the first half of 2026 and initiate a Phase 1b/2 trial in the second half of 2026.

Management Comments

• We believe that our existing cash, cash equivalents and short-term investments, together with the $7.0 million received in the first quarter from the December 2025 registered direct offering, should be sufficient to fund our operations through early third quarter of 2026.
• Our forecast of the period through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially.
• We believe that our technology platforms have the potential to address both primary and acquired resistance, the two major limitations to checkpoint inhibitor and cellular therapies and as such represents a large market opportunity.
• We believe we are uniquely positioned to identify, evaluate and potentially acquire novel drug candidates that focus on blood-related cancers that provide a strategic fit within our product pipeline and or with our DOR technology platforms.
• We believe that inhibiting MDSC functionality may represent a novel way to overcome acquired resistance to immunotherapies.
• We believe that our tumor associated MDSC-targeting ADCs have a number of potential benefits over current approaches to overcoming acquired resistance to cancer immunotherapies.

Industry Context

StockSavvy.ai notes that TuHURA Biosciences operates in the highly competitive and rapidly evolving immuno-oncology sector, characterized by significant R&D investment and high attrition rates. The company's focus on overcoming primary and acquired resistance to checkpoint inhibitors positions it within a critical area of unmet medical need, as the global checkpoint inhibitor market is projected to reach over $148 billion by 2030. The pursuit of accelerated approval pathways, like the SPA for IFx-2.0, reflects an industry trend to expedite market access for therapies addressing serious conditions. However, the substantial capital requirements and inherent uncertainties of novel biologic development are common industry challenges, and TuHURA's 'going concern' warning highlights the intense financial pressures faced by clinical-stage biotech firms.

Comparison to Industry Standards

• The global checkpoint inhibitor market is projected to grow to over $148 billion by 2030, according to Precedence Research, indicating a significant market opportunity for TuHURA's resistance-overcoming technologies.
• While 15% to 60% of patients respond to first-time checkpoint inhibitor treatment, 40% to 85% do not, highlighting the large unmet need that TuHURA's IFx-2.0 aims to address by overcoming primary resistance.
• The Phase 1b trial for IFx-Hu2.0 demonstrated a 64% overall objective response rate (7 of 11 patients) in Merkel cell carcinoma patients after re-challenge with immune checkpoint inhibitors, which is a promising signal in a difficult-to-treat population, though direct comparison to standard-of-care ORR for re-challenged patients is not explicitly provided in the filing.
• For relapsed/refractory mutated NPM1 AML, menin inhibitors show response rates of 22% to 25%, but with short duration. TuHURA's TBS-2025 aims to improve these rates, addressing a population with no approved effective therapies after menin inhibitor failure.
• TuHURA believes it is the first company developing immune modulating ADCs targeting the Delta Opioid Receptor on MDSCs, suggesting a potentially novel approach compared to traditional ADCs or checkpoint ADCs that target tumor-associated receptors or carry cytotoxic payloads.

Corporate Governance

Legal Proceedings

• On December 12, 2025, TuHURA Biosciences, Inc. filed an action in the Delaware Court of Chancery against VGXI, Inc. and GeneOne Life Sciences, Inc. (C.A. No. 2025-1447-NAC).
• The action alleges breach of contract concerning the defendants' alleged failures to produce GMP-grade plasmid DNA on a timeline required for the Merkel cell carcinoma clinical trial.
• The action also alleges fraud in inducing TuHURA to enter the contract and subsequently refrain from exercising rights to terminate and seek cover.
• The case is in its early stages, with discovery not yet commenced, and TuHURA intends to vigorously pursue its claims while remaining open to settlement discussions.

Related Party Transactions

• On October 27, 2025, the company entered into a Secured Promissory Note and Loan Agreement with an accredited investor and shareholder for an aggregate principal amount of up to $3,000,000. This loan was partially repaid and partially converted into common stock.

Stakeholder Impact

• **Shareholders**: Face significant dilution risk from ongoing and future capital raises (ATM, RDO, Private Placement) and potential adverse impact on share price due to substantial losses, going concern warning, and market volatility. The increase in authorized common stock also facilitates future dilution. However, successful clinical trial outcomes and product approvals could lead to significant upside.
• **Employees**: The company's ability to attract and retain key scientific, medical, commercial, and management personnel is crucial for its success, especially given the competitive industry. Stock-based compensation plans are in place to incentivize personnel. Former Kineta employees received separation payments in shares, indicating a commitment to integration post-merger.
• **Customers (future patients)**: Potential for novel therapeutics (IFx-2.0, TBS-2025, DOR ADCs) to address unmet medical needs in cancer treatment, particularly for patients with primary and acquired resistance to existing immunotherapies. The accelerated approval pathway for IFx-2.0 could bring a new treatment option to Merkel cell carcinoma patients sooner.
• **Suppliers/Creditors**: The 'going concern' warning and reliance on future financing pose a risk to the company's ability to meet its financial obligations. The legal dispute with VGXI, Inc. and GeneOne Life Sciences, Inc. highlights potential issues with manufacturing partners.
• **Regulatory Authorities**: The company is subject to extensive and rigorous regulation by the FDA and other governmental agencies. Compliance with SPA agreements, cGMP, GCP, and cGTP is critical for product development and approval. Any non-compliance or adverse events could lead to delays, restrictions, or withdrawal of approvals.

Next Steps

• Enrollment for the IFx-2.0 Phase 3 trial is anticipated to take approximately 18-24 months from June 2025, with top-line data potentially available 6-7 months following the last patient enrolled.
• Discuss TBS-2025 development plans with the FDA late in the first half of 2026.
• Initiate the planned Phase 1b/2 trial for TBS-2025 in r/r mut NPM1 AML as early as the second half of 2026.
• Select a lead compound for the Delta Opioid Receptor (DOR) bi-specific/bi-functional ADCs to incorporate into preclinical development.
• Seek and establish partnerships with large pharmaceutical or biotech companies for development and commercialization of product candidates to secure non-dilutive capital and funding.
• Continue to raise additional capital through public or private equity offerings, debt financings, collaborations, and licensing arrangements to fund operations beyond early Q3 2026.
• Vigorously pursue claims against VGXI, Inc. and GeneOne Life Sciences, Inc. in the breach of contract and fraud legal action.

Key Dates

Recommendation

TuHURA Biosciences presents a high-risk, high-reward profile. While the company is advancing multiple promising immuno-oncology candidates, including a Phase 3 trial for IFx-2.0 with an FDA SPA, and has strategically acquired TBS-2025, its significant and increasing net losses, substantial accumulated deficit, and explicit 'going concern' warning indicate severe financial instability. Recent capital raises provide short-term liquidity but highlight ongoing dilution. The potential for groundbreaking therapies is offset by the inherent uncertainties of clinical development, regulatory approval, and commercialization, compounded by intense competition and a legal dispute. A 'hold' recommendation is appropriate for investors who are already exposed and believe in the long-term potential of the pipeline, but new investors should exercise extreme caution due to the high financial risk and the need for substantial future capital.
