Thank you, John. First, let me say how excited I am to be part of Cirrus Logic. I really look forward to supporting and helping shape the company's strategic vision and our plan for long-term growth in both revenue and profitability. I believe we have a great opportunity to drive compelling returns and shareholder value. Now Q4 was a record fourth quarter with stronger-than-expected results that drove record revenue and EPS for fiscal '22. Fourth quarter revenue was $490 million, up 67% from a year ago. For the full year, revenue was a record $1.78 billion, a 30% increase from a year ago. These outstanding results were driven by high-performance mixed-signal content gains in smartphones, and to a lesser extent, sales of fast-charging ICs in smartphones as well as audio products in laptops. Non-GAAP gross profit in the quarter was $259 million or 52.9% of revenue. Gross margin was roughly flat sequentially and but up 240 basis points year-over-year. The year-over-year increase in gross margin was driven by higher ASPs, which were partially offset by supply chain cost increases. Going forward, we expect gross margin to moderate towards our long-term model, and I'll cover this topic more in the guidance section. Non-GAAP operating expenses in the quarter were $123 million, up approximately $8 million sequentially. The sequential increase was primarily due to higher employee expense and to a lesser extent, an increase in product development costs. For the full fiscal year, non-GAAP operating expenses were $456 million or 26% of revenue. Non-GAAP operating income was $136 million in the fourth quarter or 28% of revenue representing a record for the quarter. Full year operating income was $472 million or 27% of revenue. Non-GAAP net income in the fourth quarter was $118 million, or $2.01 per share. For fiscal year '22, non-GAAP net income was $408 million or $6.90 per share. Let me now turn to the balance sheet. Our balance sheet is strong, and we ended fiscal year '22 with $444 million in cash and cash equivalents. This was up roughly $173 million from the prior quarter due to strong cash flow generation. We have no debt outstanding. Inventory was $138 million, down $10 million sequentially; and days of inventory was 55 days in Q4, up three days sequentially. Turning to the cash flow. Cash flow from operations was $258 million in the quarter. And free cash flow for the quarter was $250 million and for the full year was $95 million as we used $277 million in cash for the Lion acquisition as well as $255 million for wafer purchase commitments. We are pleased with the results of our capital return activities during the year. We repurchased roughly $75 million of our common stock in fiscal Q4 and a total of $167.5 million during the full fiscal year. As of the end of fiscal year '22, we have $192.5 million remaining in our current share repurchase authorization. And now on to the guidance. For the first fiscal quarter of 2023, we expect revenue in the range of $350 million to $390 million. On a year-over-year basis, our expected revenue growth is primarily driven by anticipated increases in demand for certain components, shipping and smartphones and to a lesser extent higher ASPs compared to the prior year. As I alluded to earlier, we expect gross margins to normalize around a long-term model of 50% as we ship inventory built at higher cost compared to Q4 fiscal '22. As a result, in the June quarter, we expect gross margin to range from 49% to 51%. Non-GAAP R&D and SG&A is expected to be flat sequentially, in the range of $117 million to $123 million. We anticipate a tight labor market in fiscal 2023 with associated inflationary pressures on wages. On the tax front, due primarily to a tax rule effective this year that requires companies to capitalize and amortize R&D expenses rather than deduct them in the current year, we expect our fiscal '23 non-GAAP effective tax rate to increase to approximately 23% to 25%. However, we anticipate that under this rule, our effective tax rate will decrease and may return to a normalized range in about five years as additional years of R&D expenses are amortized for tax purposes. There appears to be strong legislative support for delaying or eliminating this rule, which we’re watching closely. I'd note that without the impact of this rule, our non-GAAP effective tax rate would be in our more typical mid-teens range. In closing, we had an outstanding fiscal Q4 and fiscal year 2022. Going forward, we will focus on the best opportunities to enable the company to continue to grow both revenue and profitability over the long term. Finally, I want to thank Thurman for his leadership and contributions to Cirrus over the past two decades and for building a world-class finance organization. And before we begin the Q&A, I'd like to note that while we understand there is intense interest related to our largest customer, in accordance with Cirrus Logic company policy, we will not discuss specifics about our business relationship. With that, let me turn the call to Chelsea to start the Q&A session.
