The TL;DR
πŸ’°
What Happened
Revenue: $277M (+71% YoY, +8% QoQ) missed $280M estimate by 6% with fee revenue $259M offset by $19M net interest income from balance sheet

Adj EPS: $0.52 crushed $0.42 estimate with GAAP EPS $0.23 aided by $7.2M gain on convertible debt repurchase

Conversion Drop: 20.6% from 23.9% in Q2 as models responded to UMI rising 0.2 points in July/August before reverting

Applications Surge: 2M+ applications (+30% QoQ) reached highest level in 3+ years despite conservative underwriting

Volume Growth: 428K transactions (+128% YoY, +15% QoQ) with 300K new borrowers and average loan size $6,670 (-12% QoQ)
πŸ“ˆ
Why It Matters
Feature Not Bug: CEO Dave Girouard emphasized model conservatism is "a feature, not a bug" proving system working as designed

$50B Milestone: Platform generated $50B+ in AI-powered loans since inception with 98M borrower repayment events providing unmatched training data

Calibration Breakthrough: CTO Paul Gu announced 50% reduction in unwanted month-to-month conversion volatility from model improvements

Funding Strength: 10 active private credit partners with 100% retention, 7 new bank partners (best quarter for new logos), all-time high monthly funding capacity

Fastest Response Time: Models detect changes in borrower behavior faster than traditional backward-looking credit metrics like charge-offs
🎯
What's Next
Q4 Guidance: Revenue $288M (+4% QoQ) with fee revenue $262M, NII $26M, contribution margin 53%, Adj EBITDA $63M, GAAP net income $17M

Full Year 2025: Revenue $1.035B (fees $946M, NII $89M), Adj EBITDA margin 22%, GAAP net income $50M marking return to profitability

Balance Sheet Strategy: Multiple funding agreements across new products expected by year-end to release $1.2B invested capital

Take Rate Moderation: CFO Sanjay Datta announced plan to "dial up forward investment into customer lifetime value" by moderating take rates for higher volumes

Credit Tailwinds: Rising repayment speeds and decelerating consumption historically signal improving consumer health heading into 2026

Bottom Line for Retail Investors
Upstart's 14% post-earnings selloff creates a compelling contrarian opportunity for investors who understand what actually happened. The market punished the stock for choosing credit quality over volumeβ€”its AI models detected macro signals (UMI up 0.2 points) and proactively reduced approvals while competitors kept lending aggressively. CEO Girouard's mantra: "the model is always right" and they "don't overrule the model." At $39.88, you're paying just 3.9x forward revenue for a company that just proved its discipline with a crucial technical win: 50% reduction in model volatility. With $50B in AI loans originated, 98M repayment events (vs competitors' limited data), and 100% retention of all 10 private credit partners, this represents maximum pessimism pricing. The auto retail business doubled locations, home equity reached 20% instant approvals using multimodal AI, and applications hit a 3-year highβ€”all while maintaining exceptional credit performance. Base case $60 target (+50% upside) assumes steady execution, while bull case $85 (+113%) requires new products to scale and conversion rates to normalize. If you believe AI models that prioritize credit quality over short-term volume will win the next credit cycle, this 59% drawdown from the August peak is your entry point.

🐻 Bear Thesis
πŸ“‰
Conversion Rate Pressure
UMI Spike Impact: Upstart Macro Index rose 0.2 points in July/August triggering model conservatism before reverting

Approval Rate Mechanics: Conversion pressure from fewer approvals, slightly higher rates, and smaller approved loan sizes

Measurement Error Risk: Despite 50% volatility reduction, models still face sampling error from representing US economy with finite dataset

Q4 Lag Effect: Management expects Q3 model conservatism impact to continue affecting Q4 despite UMI improvement
⚠️
Credit Risk Exposure
Prime Segment Weakness: 720-750 FICO segment showing elevated default rates vs pre-COVID with higher UMI than subprime

U-Shaped Risk Curve: Sub-660 (UMI ~1.2-1.3) and 800+ performing well, but mid-700s segment showing elevated stress

Repayment Speed Ambiguity: Higher repayment speeds could indicate refinancing away from Upstart rather than improved borrower health

$1.2B Balance Sheet Risk: Elevated loan holdings create liquidity concerns with funding deal timing "not perfectly predictable"
🏦
Competitive Pressures
Competitor Volume Divergence: SoFi and LendingClub reported strong Q3 origination growth while Upstart's models tightened

Unknown Risk Models: Management admitted "we don't know what their models look like" when asked why competitors didn't tighten

Prime Segment Competition: Superprime (720+ FICO) showing "very competitive" environment with others posting healthy growth

Share Shift Risk: Analysts questioning if Upstart lost market share by "fighting with one hand tied behind your back" due to model conservatism
πŸ“œ
Regulatory Uncertainty
Auto Fraud Scrutiny: High-profile bankruptcies in auto lending causing banks to do "a bit more diligence" and ask more questions

Extended Timelines: CFO noted auto fraud headlines "probably lengthened timelines" with diligence lists "doubled and tripled in size"

Deal Process Heavy Lifts: Multi-year funding agreements involve "legal processes, financing, bank relationships" that are "heavy lifts"

Black Box Perception: Industry continues to view AI models as opaque despite Upstart's transparency claims about fast-moving signals
