Thank you, Frank. Good morning, everyone. Our fourth quarter finalized another great year for Photronics. In my comments, I'll first discuss the fourth quarter results, then the results for the full fiscal year. Fourth quarter revenue of $227.5 million increased 8% over fourth quarter of last year and 1% sequentially. Photronics fourth quarter always ends on October 31, which may add or subtract days to the standard 91-day 4-4-5 fiscal calendar. This year, fourth quarter was boosted by an extra two days in the quarter. It was our second highest quarterly revenue ever, only 1% off the record established in Q2 of fiscal year 2023. Our revenue into China in Q4 declined from 53% of total revenue in Q3 to 44% replaced by revenue with other customers. It might be worthwhile to add some further color regarding the China business. Although we derive a good portion of revenue from China, as do others in the semiconductor and display industry, what makes the China business somewhat unique is that there is a significant number of new designs and fabs in China driving photomask demand. And since there is a much smaller captive market in China, the preponderance of the photomask production is being provided by merchant manufacturers like Photronics. The business by major category, IC revenue of $164.5 million in the fourth quarter was up 1% sequentially and 5% year-over-year. Our high-end revenue defined as IC masks using 28 nanometer and smaller technology drove the increase with 27% sequential growth, which more than offset the reduction in mainstream revenue. High-end revenue was strong in foundry logic in both U.S. and Asia. The 9% decrease in mainstream revenue resulted in large part from lower delivery premiums due to somewhat moderated demand and more normalized lead times for those products. For the FPD product category fourth quarter FPD revenue was a record $63 million, up 3% sequentially, and 17% year-over-year, a 7% increase in high-end revenue, defined as LTPS, AMOLED and G10.5 large area masks, drove the increase from strong demand for AMOLED display masks used in mobile displays where we have technology leadership. The additional FPD production devoted to high-end mask production then resulted in 13% lower mainstream revenue. Gross margin was solid at 37.3%, although slightly lower due substantially to the decreased premiums for expedited delivery of the mainstream IC masks. Operating expenses decreased somewhat and declined as a percentage of revenue to less than 9%, helping us achieve an operating margin of 28.5% in the quarter. GAAP net income in the quarter was $44.6 million or $0.72 per diluted share. Non-GAAP net income, which eliminates foreign currency effects primarily unrealized was $37.2 million or $0.60 a share. For reference, our reconciliation of GAAP to non-GAAP results is included in the press release and supplemental slides. For the year, total revenue of $892.1 million was 8% higher than the $824.5 million reported in fiscal year 2022, the 6th straight year of record revenues, as Frank mentioned, a compound annual growth rate of 12% over the last six years. Revenue in fiscal year 2023 was nearly double the revenue of fiscal year 2017, when we repositioned the business and initiated the targeted investments to address where we anticipated growth to be in the photomask space. IC revenue for the year was a record and grew 9.8% as strong demand for mainstream masks for a good part of the year offset a slight decrease in high-end revenue, primarily in the U.S. Near-term, our investment will be primarily in IC capacity to continue outgrowing the market and take advantage of our market strength and close customer relationships. FPD revenue is also a record for the year, up 4%, with high-end growth consistently driven by AMOLED demand. We anticipate this trend to continue into fiscal 2024. Gross margins for the year were 37.7%, 200 basis points over the strong gross margin in fiscal 2022. And we anticipate the gross margin will remain in the current range through the stable pricing, cost controls, and operating leverage. Maintenance of this level of gross margin in the face of erosion of delivery premiums during the latter half of the year indicates a pricing and operating environment that supports the sustainability of the margins. Operating expense for the year was nearly unchanged from the prior year of less than $800,000 and declined as a percentage of revenue to 9.3% from 10% in the prior year. Operating margin was 28.4%, compared to 25.7% in fiscal 2022, and operating income in fiscal 2023 was $253 million. During our six years of 12% revenue growth, operating income has grown at a compound annual growth rate of 41% and operating margin quadrupled. GAAP EPS for the year was $2.03 and adjusted for the effects of foreign exchange variations, non-GAPP EPS was $2.04. GAAP EPS similarly has grown at a CAGR, compound annual growth rate, of 48% during the six years that revenue has increased 12%. Operating cash flow of $106.6 million for the quarter and $302.2 million for the year were also records for the company, resulting from higher net income and effective management of working capital. CapEx for the quarter was $21.1 million and $131.2 million for the year, which resulted in free cash flow for the year of $170.9 million. For 2024, we expect to invest $140 million in CapEx, primarily in both high-end and mainstream IC to address current and anticipated demand growth. We'll also be taking delivery of a new multi-beam lithography tool in the U.S. for development, then phase into high-end production enhancements, then leading-edge development during our fiscal year 2025. We ended the year with a cash balance of $499.3 million and short-term investments of $12.9 million. Some investments of cash that were previously classified as short-term investments have been reinvested in shorter-term instruments that are now classified as cash equivalents and included in the cash and cash equivalents balance at October 31, 2023. The aggregate of cash and cash equivalents in short-term investments increased from $358.5 million at year-end 2022 to $512.2 million at October 31, 2023. Our only remaining debt consists of low-cost equipment leases of $24.6 million. Our net cash position of $475 million provides ample liquidity to fund investments in organic growth. It also has continued to provide resilience against uncertainties inherent in an industry's downturn. We have $32 million remaining of our previous $100 million authorization to repurchase our common stock, and we will continue evaluating when to resume the share repurchase initiative. Before I provide guidance, I'll remind you that our visibility is always limited, as our backlog is typically only one to three weeks. And demand for some of our products is inherently uneven and difficult to predict. Additionally, the ASPs for high-end mask sets are high. And as this segment of the business grows, a relatively low number of high-end orders can have a significant impact on our quarterly revenue and earnings. Given those caveats, we expect first quarter revenue to be in the range of $217 million to $225 million. First quarter revenue from Photronics is typically seasonally lower than fourth quarter. And as I mentioned, this year's first quarter has fewer days than normal, 89 versus 91, in a typical 445 fiscal calendar, due to fourth quarter ending on October 31, which as I mentioned, put 93 days into the fourth quarter and shortened the first quarter. Photronics has continued to increase revenue during the entire semi downturn, while many in the industry are reporting revenue declines and the industry as a whole anticipates about a 12% decline in 2023 revenue. Due to the design driven somewhat counter cyclical nature of the business, we expect to continue to do well in the current semiconductor and display environment, continue to report year-over-year revenue growth, and increase our market-leading position. Based on those revenue expectations and our current operating model, we estimate non-GAAP earnings per share for the first quarter to be in the range of $0.45 to $0.53 per diluted share. We believe that the increasing trend of both high-end IC and FPD and our additions to capacity will continue to support healthy gross margins. Our disciplined cost control will help ensure that the gross profit flows down to operating income and earnings to continue to build shareholder value. I'll now turn the call over to the operator for your questions.
