Our Annualized Net Charge-off Rate ranged between 7% and 10.1% from 2014 to 2022. In 2020, during the pandemic, our Annualized Net Charge-off Rate was 9.8%. Due to credit tightening in response to the COVID-19 pandemic and government stimulus payments, our Annualized Net Charge-Off Rate decreased to 6.8% in 2021. Our Annualized Net Charge-off Rate increased to 10.1% in 2022 primarily due to an increasing interest rate environment, inflation and the cessation of COVID-19 stimulus payments and a higher mix of first-time borrowers in 2021 and the first half of 2022. In response to this increase, in the second half of 2022 and continuing throughout 2023 and 2024, we tightened our credit underwriting standards and focused lending towards existing and returning members to improve credit outcomes. The Annualized Net Charge-Off Rate for the three months ended September 30, 2025 and 2024 was 11.8% and 11.9%, respectively. The decrease was primarily driven bya$2.8 million decrease in Net Charge-offs, partially offset bya decrease in our Average Daily Principal balance by $86.0 million, primarily due to the sale of the credit card portfolio, from $2.76 billion to$2.67 billion for the three months ended September 30, 2024 and September 30, 2025, respectively. For the nine months ended September 30, 2025, the back book continued to season and made-up 7% of gross charge-offs while only making up approximately 2% of the loans receivable. We evaluate our loan portfolio and charge a loan off at the earlier of when the loan is determined to be uncollectible or when loans are 120 days contractually past due.

In addition to monitoring our loss and delinquency performance on an owned portfolio basis, we also monitor the performance of our loans by the period in which the loan was disbursed, generally years or quarters, which we refer to as a vintage. We calculate net lifetime loan loss rate by vintage as a percentage of original principal balance. Net lifetime loan loss rates equal the net lifetime loan losses for a given year through September 30, 2025 divided by the total origination loan volume for that year.

The below chart and table show our net lifetime loan loss rate for each annual vintage of our personal loan product since 2014, excluding loans originated from July 2017 to August 2020 and beginning December 2023 under a loan program for borrowers who did not meet the qualifications for our core loan origination program; 100% of those loans were sold pursuant to a whole loan sale agreement. Cumulative net lifetime loan losses for the 2015, 2016, 2017, and 2018 vintages increased partially due to the delay in tax refunds in 2017 and 2019, the impact of natural disasters such as Hurricane Harvey, and the longer duration of the loans. The 2018 and 2019 vintages were increasing due to the COVID-19 pandemic. The 2021 vintage is experiencing higher charge-offs than prior vintages primarily due to a higher percentage of loan disbursements to new members. We tightened credit, reduced loan size and loan term, and began reducing loan volumes to new and returning members beginning in the third quarter of 2022. Net Lifetime Loan Loss Rates on vintages originated since significant July 2022 credit tightening are performing near comparable vintages originated in 2019 for the first 7 to 9 months on books but start to diverge due to underperformance of larger loans relative to 2019 and due to longer average term length. In the second half of 2023 we did further tightening and shortened average term length which resulted in stronger performance of the 2023 vintages in the second half of the year as compared to the 2022 vintages for the same period. Higher costs for food, fuel, and rent along with macro-economic uncertainty have also put pressure on our members. We employ collection strategies and tools to help customers make ongoing payments against their loans, with new efforts launched that: expanded the frequency and content of our digital and telephony communications; broadened eligibility for collection tools that help customers address payment difficulties; and eased customer access to those collection tools via new online and mobile app self-enrollment capability, supported by a new collections strategy system that enables centralized, faster, and more-targeted application of strategies.

Seasonality

Our quarterly results of operations may not necessarily be indicative of the results for the full year or the results for any future periods. We experience significant seasonality in demand for our loans, which is generally lower in the first quarter. The seasonal slowdown is primarily attributable to high loan demand around the holidays in the fourth quarter and the general increase in our borrowers’ available cash flow in the first quarter, including from cash received from tax refunds, temporarily reducing our borrowers’ borrowing needs.
