• Future clinical trial outcomes for pipeline candidates (AV access, PAD, CABG, BVP) are uncertain and failure could significantly harm prospects.
• Manufacturing complexities, including potential batch failures, contamination risks, and challenges in scaling production, could disrupt supply.
• The company requires substantial additional funding to finance operations, clinical trials, manufacturing scale-up, and commercialization efforts, which may not be available on favorable terms or at all.
• Uncertainty exists regarding third-party payor coverage and reimbursement levels for Symvess and future products.
• Reliance on the strategic partnership with Fresenius Medical Care for ex-U.S. commercialization carries risks if the partner does not perform as expected.
• Protection and enforcement of intellectual property rights for the novel technology platform are critical and may face challenges.
• Potential for product liability claims related to the novel bioengineered tissues.
• Ongoing regulatory scrutiny and compliance requirements post-approval for Symvess and for manufacturing facilities.
• Cybersecurity threats pose risks to sensitive data and complex manufacturing systems.
• The terms of the Revenue Interest Purchase Agreement with Oberland affiliates impose financial obligations and covenants.
• Potential for adverse events or side effects to emerge with wider clinical or commercial use of ATEVs.

Future Outlook

Humacyte plans to continue the U.S. commercialization of Symvess for vascular trauma. Based on interim results from the ongoing V012 Phase 3 trial, the company targets submitting a supplemental BLA to the FDA for an AV access indication in the second half of 2026. An IND application for CABG is planned for 2025, along with an orphan drug application for pediatric heart surgery. Preclinical development of the BioVascular Pancreas will continue. The company anticipates needing additional capital to fund these activities and expects operating losses to continue for the foreseeable future.

Management Comments

• Management believes the company's regenerative medicine technology has the potential to overcome limitations in existing standards of care and transform the practice of medicine.
• Management highlights the potential for ATEVs to become the standard of care in vascular repair, reconstruction, and replacement, leading to improved patient outcomes and lower healthcare costs.
• The company intends to continue shaping its commercial strategy by indication and pursue collaborations where partners provide strategic opportunities.
• Management believes its established, controlled manufacturing process represents a significant competitive advantage.
• Management believes existing cash, along with capacity under the Lincoln Park agreement and considering management plans, will fund operations at least into mid-2026, but acknowledges the need for additional capital beyond that.

Industry Context

Humacyte operates in the biotechnology and regenerative medicine sectors, specifically focusing on tissue engineering for vascular applications. Its ATEV technology aims to address significant unmet needs and limitations associated with current vascular repair options like autologous vein harvesting (morbidity, time constraints, availability issues) and synthetic grafts (infection risk, lack of remodeling). The development of an 'off-the-shelf', universally implantable, bioengineered human tissue represents a novel approach compared to traditional grafts and could disrupt the multi-billion dollar vascular reconstruction market if successfully adopted.

Comparison to Industry Standards

• In the V005 trauma trial, the ATEV demonstrated a 30-day secondary patency of 90.2% and an infection rate of 2.0%, comparing favorably to historical synthetic graft benchmarks of 78.9% secondary patency and 8.4% infection rate.
• In the V017 Ukraine humanitarian program (trauma), the ATEV showed 93.8% 30-day secondary patency and 0% infection rate.
• In the V006 Phase 3 AV access trial, the ATEV showed a statistically significant lower rate of conduit infections (0.93% per year) compared to ePTFE grafts (4.5% per year), although it did not meet the primary endpoint for secondary patency compared to ePTFE (ATEV 67% vs ePTFE 74% at 24 months).
• In the V007 Phase 3 AV access trial, the ATEV demonstrated superior functional patency at 6 months (81.3% vs 66.4%, p=0.0071) and secondary patency at 12 months (68.3% vs 62.2%) compared to AV fistula, the current standard of care, particularly in subgroups like women and patients with obesity/diabetes.
• In Phase 2 PAD trials (V002, V004), ATEVs showed promising patency rates (e.g., V002 6-year secondary patency of 60%) and zero graft infections, with no amputations reported in V004 despite treating severe PAD patients (Rutherford 4/5) lacking autologous vein.
• Competitors in the vascular graft market include established players with synthetic grafts like Bard Peripheral Vascular, W.L. Gore & Associates, Terumo, and Atrium (Maquet Getinge Group).
• Other graft types include xenografts (e.g., Artegraft, Procol) and allografts (e.g., CryoVein, AngioGRAFT), which have limitations regarding immunogenicity, durability, or availability.
• Emerging competitors in tissue-engineered or novel vascular conduits include NovaHep AB, Xeltis AG, Hancock Jaffe, and Vascudyne Inc.

Legal Proceedings

• A putative securities class action lawsuit (Cutshall v. Humacyte, Inc.) was filed on November 18, 2024, alleging false or misleading statements related to the BLA and manufacturing deficiencies.
• Two verified stockholder derivative actions (Silva v. Sebelius, Misko v. Niklason) were filed in January 2025, asserting claims including breach of fiduciary duty related to the securities litigation.
• These two derivative actions were consolidated and stayed pending resolution of the securities litigation.
• A demand letter was received from a purported stockholder on December 19, 2024, leading to the formation of a demand evaluation committee by the Board.
• A third stockholder derivative action (Olson v. Niklason) was filed on February 19, 2025, with similar allegations to the consolidated derivative action.
• The company disputes all claims asserted in these lawsuits and is currently unable to estimate potential loss.

Related Party Transactions

• Fresenius Medical Care is a significant shareholder and holds exclusive distribution rights for certain ATEV products and indications outside the U.S./EU, collaborates on U.S. commercialization, and its subsidiary Frenova Renal Research provides CRO services for Humacyte trials.
• Yale University is a licensor of key patents related to BVP and tubular prostheses; CEO Dr. Laura Niklason serves as an Adjunct Professor at Yale.
• Duke University is a licensor of patents related to decellularized tissue engineering, requiring milestone and royalty payments.

Stakeholder Impact

• Shareholders face potential dilution from ongoing equity financing activities needed to fund operations but may benefit from successful commercialization and pipeline advancement.
• Patients with specific vascular conditions (trauma, potentially AV access, PAD) gain access to a novel treatment option with Symvess.
• Employees benefit from the company's growth and potential success but face risks associated with a clinical-stage company's financial stability and commercial execution.
• Suppliers (like SeraCare, Confluent) are critical partners, with potential for increased business but also concentration risk for Humacyte.
