Thank you, Jerry. And welcome, everyone. A year ago, you joined me on our earnings call as we talked about our expectations for 36% revenue growth for 2022. A lot has happened between that initial guidance and now.
And even in the face of a more challenging economic environment, we continuously raise our guidance as we move through the year and delivered 47% revenue growth in 2022. We delivered that growth efficiently with an adjusted operating income margin of 41% for the year and more than $450 million in unlevered free cash flow. In the fourth quarter, we delivered over $300 million in revenue with a 42% adjusted operating income margin, which was up 100 basis points sequentially and up more than 350 basis points from Q4 last year. Structurally, we are a profitable company, and we remain committed to driving top-line growth while expanding profitability and efficiently growing free cash flow.
