• Upstart prepared for Q2 2026 earnings release with focus on key financial metrics and market expectations [N4].
• The company signed a $4 billion loan sale agreement with Castlelake, indicating active capital market engagement [N6].

Upstart's AI-driven underwriting platform offers a differentiated approach to credit risk assessment, potentially expanding credit access to underserved borrowers and reducing borrowing costs. The high degree of automation supports operational efficiency and scalability. The company's diversified capital base, including institutional investors and lending partners, provides flexibility in funding loan originations. Expansion into auto loans and HELOCs diversifies product offerings beyond personal loans. Continuous AI model improvements and data accumulation may enhance credit decisioning and marketplace performance.

Upstart faces risks from economic downturns that can reduce borrower demand and increase defaults, impacting loan performance and capital availability. Dependence on a limited number of lending partners and institutional investors could affect funding stability. AI model inaccuracies or delays in adapting to changing economic conditions may lead to suboptimal loan pricing and credit losses. Regulatory changes and compliance challenges could increase costs or restrict operations. Operational risks include data security breaches and platform disruptions. Holding loans on the balance sheet exposes Upstart to credit risk and interest rate sensitivity.

Upstart's competitive advantage stems from its proprietary AI models trained on extensive and diverse data, enabling superior risk separation compared to traditional credit scoring systems. The complexity and volume of data, combined with advanced machine learning techniques, create high barriers to entry for competitors. The platform's high automation level reduces costs and improves scalability. Additionally, Upstart's broad ecosystem of lending partners and institutional investors provides diversified capital sources and resilience. The company's continuous investment in AI and data science fosters a flywheel effect, enhancing model accuracy and marketplace efficiency over time.

• Economic and Market Conditions: Adverse macroeconomic factors such as recessions, inflation, and interest rate changes can reduce borrower demand, increase defaults, and constrain capital availability, negatively impacting Upstart's business and financial results.
• Capital Funding Risks: Upstart relies on diverse capital sources including institutional investors and lending partners. Disruptions or reductions in capital supply, or unfavorable financing terms, could limit loan originations and increase funding costs.
• AI Model Performance: The effectiveness of Upstart's AI models is critical. Model errors, outdated data, or failure to adapt to economic changes can lead to poor credit decisions, increased losses, and reduced investor and lender confidence.
• Regulatory and Compliance Risks: Upstart operates in a highly regulated environment. Changes in laws, enforcement priorities, or failure to comply with regulations could result in sanctions, increased costs, or operational restrictions.
• Operational and Security Risks: Dependence on technology and data exposes Upstart to risks from system failures, cyberattacks, data breaches, and third-party vendor issues, which could harm reputation and financial performance.
• Concentration Risks: A significant portion of loan originations and revenue comes from a few lending partners, creating dependency that could affect business stability if relationships change.
• Balance Sheet Exposure: Holding loans on its balance sheet exposes Upstart to credit risk and interest rate fluctuations, which can affect liquidity and earnings.
