Thank you. Good morning, and thank you for joining our fiscal 2027 first quarter earnings call. Before turning to the numbers, I want to thank our team members across our company for the work they do every day serving our customers. The results we are reporting this quarter are a direct reflection of their execution and discipline. We are pleased with the first quarter results, and more importantly, believe we are well positioned for the remainder of fiscal 2027. This quarter reflects steady progress against our core priorities. Growing the loan portfolio value responsibly, improving credit quality, and maintain a disciplined approach to expenses. We achieved adjusted earnings per share of $2.12 for the first quarter. Earnings benefited from a 4.8% increase in revenue as well as a 13.4% decrease in provision expense. The revenue increase is due to continued year-over-year loan growth as well as a 91 base point increase in interest and insurance yields. our credit quality continued to improve as well our annualized net charge off rate decreased from 19.2 percent in the first quarter of last year to 18.2 percent in the current quarter we also saw improvement in delinquency sorry on both the front end and back end most notably front end delinquency decreased from 19.2 percent to 18.1 percent these trends reinforce our confidence in the health of the portfolio and the strength of our underwriting our expenses outside of one-time costs related to the ceo transition we saw modest increases in our gna expense and we expect to maintain this discipline approach to expenses going forward at this time tobin turner our chief operating officer and i would like to open up to any questions you may have thank you we will now begin the question and answer session To ask a question, you may press star then 1 on your telephone keypad.

If you're using a speakerphone, please pick up your handset before pressing the keys. To withdraw your question, please press star then 2. At this time, we will pause momentarily to assemble our roster. The first question comes from Kyle Joseph with Stevens. Please go ahead.
Hey, good morning. Thanks for taking my questions. I just wanted to get a sense for the kind of the timing in terms of the underwriting changes, when you guys tweaked them tighter and at what point, you know, you kind of undid those changes.
Kyle, hey, thanks. Great question. This is Tobin. We really tightened our portfolio, the whole credit box, really about six months ago, kind of coinciding with the rise in gas prices. Thankfully, we've been pretty pleased with that's the way our portfolio has aged. Probably about a month ago, we started generally loosening a little bit, but I'd say we're still fairly conservative, and with gas prices continue to spike a little bit, I like where we are. We're more open than we were five months ago, but we're still pretty conservative.
Got it. And then on the demand side, can you give us a sense for how things have trended, call it year to date? You know, we had large tax refunds, but to your point, you know, a lot higher gas prices and just sort of any, you know, any changes in demand you've observed?
Demand has been, thankfully, pretty robust for us. The bookable apps we've seen have kind of decreased a little bit in conjunction with our tightening of the credit box. But overall or systemically, we don't see a shrinking in demand. So we feel pretty comfortable with demand right now. Great.
That's it for me. Thanks for taking my questions.
