At this time, I'd like to now turn the call over to our company's Chairman and President, Mr. S.J. Cheng. Please go ahead, sir.

S.J. Cheng: Yes. Thank you, G.S. We appreciate everyone joining our call today. We are very pleased with our strong results in the face of broader industry headwinds and market challenges. We continue to carefully add capacity, expand our leadership, and build value for shareholders. In terms of Q4 and full year highlights, our Q4 revenue increased 22.2% compared to Q4 2022, and was up 2.6% from Q3 2023. Full year 2023 revenue declined 9.2% compared to 2022 reflecting industry headwinds and inventory corrections. Q4 gross margin increased 560 basis points to 20.1% from 14.5% in Q4 2022, and increased 420 basis points compared to Q3 2023. Overall, gross margin decreased 430 basis points for 2023 to 16.6% compared to 2022. Net Earnings tripled to NT$ 0.66 in Q4 2023 from NT$ 0.22 in Q4 2022 but decreased NT$ 0.14 compared to NT$ 0.8 of Q3 2023. Overall, 2023 is NT$ 2.60. Our overall utilization rate was 62% in Q4 2023. Assembly utilization increased to 57% and Testing average was 61%. DDIC was at 71% and Bumping UT level decreased to 53%. Regarding our manufacturing business, our assembly represented 23.2% of Q4 revenue. Mixed-signal and memory Testing represented around 19.9% and wafer bumping represented around 20.4% of Q4 revenue. On a product basis, our DDIC product represented around 37.1%, with gold bumping representing about 18.9%. Revenue from DRAM and SRAM represented around 17.2% of Q4 revenue. Our Mixed-signal products represented about 7.8%. As additional color on our business, our memory products represented about 36.2% of total Q4 revenue. Memory product revenue was up about 9.5% compared to Q3 2023, and increased 9.9% on a year-over-year basis. This is inline with broader industry trends as customers adjust inventory levels. DRAM revenue increased up 28.4% compared to Q3 and represented about 16.9% of total Q4 revenue. The significant growth came from domestic customers restocking and increasing DRAM rush assembly orders in Q4 to meet demand. Flash revenue represented about 19% of Q4 revenue, which down just slightly 2.2% compared to Q3. NAND Flash also benefitted significantly from customers restocking and increased about 22.4% compared to Q3, and represented about 37.8% of Q4 total Flash revenue. Moving onto Driver IC and gold bump revenue, this represented about 56% of total Q4 2023 revenue and was up significantly around 40.5% on a year-over-year basis, but decreased 2.6% compared to Q3 2023. Strong growth offset some pockets of softness. Of note, Gold bump revenue was down 9% compared to Q3 2023 and DDIC revenue was little up about 0.9% compared to Q3 2023. In line with what we have said on prior calls, Automotive has been a strong market for us over the past year. This continued in Q4 with revenue from Auto panels increasing about 11.8% from Q3 and accounting for more than 25% of our Q4 DDIC revenue, and more than 23% of 2023 full year DDIC revenue. We continue to view Automotive as an important mid and long-term growth market for us. For example, we benefited from Automotive panels and OLED, which led to a 7.7% increase in our COG revenue compared to Q3, and represented about 64% of Q4 DDIC revenue. Regarding TDDI, it represented around 17.1% of Q4 DDIC revenue, with OLED at about 17.2% of Q4 DDIC revenue, which is significantly up 20.5% compared to Q3 OLED revenue. On an end-market basis, total revenue from Automotive and Industrial was up 6.9% compared to Q3 and represented about 21.2% of Q4 revenue.

Lastly, TVs and Computing as an end market, accounted about 14.7% and 4.9%, respectively. Now, let me turn the call to Ms. Silvia Su, to review the fourth quarter and full year 2023 financial results. Silvia, please go ahead.

Silvia Su: Thank you S.J. All dollar amounts cited in our presentation are in NT dollars. The following numbers are based on the exchange rates of TWD30.62 against $1 as of December 29, 2023. All the figures were prepared in accordance with Taiwan-International Financial Reporting Standards. Referencing presentation Page 12 consolidated operating results summary. For the fourth quarter of 2023, total revenue was TWD5,725 million. Net profit attributable to the company was TWD482 million in Q4. Net earnings for the fourth quarter of 2023 were TWD0.66 per basic common share or $0.43 per basic ADS. EBITDA for Q4 was TWD1,872 million. EBITDA was calculated by adding depreciation and amortization together with operating profit. Return on equity of Q4 was 7.8%. Referencing presentation Page 13 consolidated statements of comprehensive income. Compared to 3Q 2023, total 4Q 2023 revenue increased 2.6% compared to 3Q 2023. 4Q 2023 gross profit was TWD1,150 million, with gross margin at 20.1% compared to 15.9% in 3Q 2023. This represents an increase of 4.2 ppts. Our operating expenses in 4Q 2023 were TWD445 million or 7.8% of total revenue, which increased 1.3% compared to 3Q 2023. Operating profit for 4Q 2023 was TWD715 million, with operating profit margin at 12.5%, which is about a 3.8 ppts increase compared to 3Q 2023. Net non-operating expenses in 4Q 2023 were TWD 137 million compared to net non-operating income of TWD 231 million in 3Q 2023. The difference is mainly due to the increase of the foreign exchange losses of TWD 362 million to the foreign exchange losses of TWD 195 million in 4Q 2023 from the foreign exchange gains of TWD 167 million in 3Q 2023 and the decrease of rental income of TWD 9 million. Profit attributable to the Company in 4Q 2023 decreased 17.0% compared to 3Q 2023. This primarily reflects an increase of net non-operating expenses of TWD 368 million and partially offset by the increase of operating profit of TWD 227 million and the decrease of income tax expense of TWD 42 million. Basic weighted average outstanding shares were 727 million shares. Compared to 4Q 2022, total revenue for 4Q 2023 increased 22.2% compared to 4Q 2022. Gross margin at 20.1% increased 5.6 ppts compared to 4Q 2022. Operating expenses increased 6.7% compared to 4Q 2022, still well below the revenue growth rate. Operating profit margin at 12.5% increased 5.9 ppts compared to 4Q 2022. Net non-operating expenses increased TWD 7 million compared to 4Q 2022. Profit attributable to the Company increased 211.2% compared to 4Q 2022. The difference is mainly due to an increase of operating profit of TWD 404 million and partially offset by the increase of income tax expense of TWD 70 million and net non-operating expenses of TWD 7 million. Referencing presentation Page 14 Consolidated Statements of Comprehensive Income. Compared to last year, total revenue for 2023 was TWD 21,356 million, which decreased 9.2% compared to 2022. Gross margin at 16.6%, decreased 4.3 ppts compared to 2022. Our operating expenses in 2023 were TWD 1,727 million, which decreased 5.4% compared to 2022. Operating profit margin in 2023 was 8.9%, a decrease of 4.8 ppts compared to 2022. Net non-operating income in 2023 was TWD 360 million. The difference was mainly due to a decrease of the foreign exchange gains of TWD 370 million, share of profit of associates accounted for using equity method of TWD 234 million and partially offset by an increase of interest income of TWD 136 million. Net profit in 2023 was TWD 1,893 million, which decreased 43.8% compared to 2022. The difference due to a decrease of the operating profit of TWD 1,308 million and net non-operating income of TWD 451 million and partially offset by the decrease of income tax expense of TWD 281 million. Net earnings for the full year 2023 were TWD 2.60 per basic common share compared to TWD 4.64 per basic common share for the full year 2022. Referencing presentation Page 15 Consolidated Statements of Financial Position & Key Indices. Total assets at the end of 4Q 2023 were TWD 46,161 million. Total liabilities at the end of 4Q 2023 were TWD 21,307 million. Total equity at the end of 4Q 2023 was TWD 24,854 million. Accounts receivable turnover days in 4Q 2023 were 86 days. Inventory turnover days was 53 days in 4Q 2023. Referencing presentation Page 16 consolidated statements of cash flows. As of December 31, 2023, our balance of cash and cash equivalents was TWD 12,354 million, which represents an increase of TWD 2,457 million compared to the beginning of the year. Net free cash inflow for the full year 2023 was TWD 1,339 million compared to net free cash outflow of TWD 818 million for the full year 2022. The increase was mainly due to the decrease of operating profit of TWD 1,308 million and partially offset by the decrease of CapEx of TWD 1,690 million, cash dividend paid TWD 1,454 million and income tax expense of TWD 281 million. Free cash flow was calculated by adding depreciation, amortization, interest income together with operating profit and then subtracting CapEx, interest expense, income tax expense and dividend from the sum. Referencing presentation Page 17 capital expenditures and depreciation. We invested TWD 1,499 million in CapEx in Q4 and TWD 3,228 million in CapEx in 2023. The breakdown of CapEx in Q4 was 4% for bumping, 61.6% for LCD Driver, 15.5% for assembly and 18.9% for testing. Depreciation expenses were TWD 1,158 million in Q4. Depreciation expenses were TWD 4,779 million in 2023. As of January 31, 2024, the company’s outstanding ADS number was approximately 4.2 million units, which represents around 11.5% of the company’s outstanding common shares. That concludes the financial review. I will now turn the call back to our Chairman Mr. S.J. Cheng for our outlook. Please go ahead, sir.

S.J. Cheng: Thank you, Silvia. As we come off a strong Q4, we expect the normal Q1 seasonality from fewer working days and the Lunar New Year. We are also seeing signs that inventory adjustments from Q4 will continue into Q1. We are very confident in our long-term business and any fluctuations would be more short-term in nature. We expect Q1 to be the trough quarter for 2024, which is inline with normal seasonal patterns. We expect our operating momentum will improve as we move through the year with the second half of 2024 coming in better than the first half. This is also in line with what we have heard from some of the largest semiconductor companies. In our memory product, despite assembly and test UT are impacted by the continued destocking and softer demand at certain customers. However, we are still benefiting from rebounding NAND Flash demand. Therefore, we think memory will outgrow DDIC product momentum in Q1. In our DDIC product, the UT level of TV and smart phone products is impacted by softness in end product demand. That said, we expect Automotive panel and OLED demand to remain stable compared to other products. Part of this is underlying industry demand. The other important driver continues to be new customer programs ChipMOS has been ramping. This leads to the high UT level of high-end DDIC test platforms. In the meantime, we also remain positive on Automotive and OLED panels, which are the majority of our customer's new DDIC projects. We are taking a conservative approach with our CapEx budget in 2024, similar to 2023. We plan to carefully invest in Green Energy, Automation, Robotics and AI. Regarding to the new added capacity, including the DDIC high-end test platform will be based on further customer demand and UT level in support of our customers, as we drive strong free cash flow and maintain our competitive advantage and strength. Finally, in terms of our capital allocation, our Board approved another dividend. This reflects our balance sheet strength, strong market position and our focus on building shareholder value. We prioritize returning capital to shareholders as part of our overall shareholder-friendly capital allocation plan. Pending shareholder approval at our May AGM, we will distribute TWD1.8 per common share. Operator, that concludes our formal remarks, we can now take questions.

Operator: Thank you. At this time, we will be conducting a question-and-answer session. Our first question comes from Angela Dai from UBS. You may begin.

Angela Dai: Why did gross margin go up so much in Q4?

S.J. Cheng: Margin is a constant focus for us. In Q4, several factors impacted gross margin, including mix and variable costs. We saw much lower electricity charges in Q423, including a lower rate charged and consumption decreased TWD86 million compared to 3Q23, and lower gold material charges by about TWD45 million, compared to 3Q23. Meanwhile, the depreciation in Q423 decreased around TWD53 million, compared to Q323.

Angela Dai: Could you provide a more detailed outlook about 1Q24, for revenue and gross margin?

S.J. Cheng: We expect Q124 to be the normal trough quarter for 2024, which is in line with typical seasonal patterns. We expect our operating momentum will improve as we move through the year with the second half of 2024 coming in better than the first half. Overall we are targeting positive annual revenue growth in 2024.

Operator: Our second question comes from Stanley Wang from SinoPac.

Stanley Wang: What is your CapEX, depreciation and effective income tax rate for 2024?

Silvia Su: According to our budget, we are taking a conservative approach with our CapEx in 2024 expected to similar to 2023 or around 15% of annual revenue. On the basis of 4Q23, the depreciation rate would increase around 1% to 3% quarterly. The effective tax rate will be around 17% to 19% in 2024.

Q – Stanley Wang: Please give me more color on the CapEx increase QoQ from DDIC?

Jesse Huang: The CapEx was used mainly for high-end testers in Q423.

Q – Stanley Wang: What is the DDIC high-end tester utilization rate after Lunar New Year holiday?

S.J. Cheng: The high-end tester utilization rate still maintains at a high level. However, the mid to low end tester utilization rate declined.

Q – Stanley Wang: Please give us more color about revenue for the first half and second half of 2024?

Silvia Su: A rough estimation for the first half would be around 46% to 47% and the second half would be around 53% to54%.

Q – Stanley Wang: Comparing revenue and gross margin for the growth momentum of 2024, which one could perform better?

S.J. Cheng: We see positive revenue growth. However, we would also be impacted by cost increases of green energy requirements and electricity charges.

Q – Stanley Wang: Please give me more color about wafer bank digestion by product line.

Jesse Huang: We think memory will outgrow DDIC product momentum in Q124. The level of memory, NAND flash demand from module customers appears to be better than the others.

Q – Stanley Wang: The Company benefited from automotive market demand in 2023, however, the end demand seems to be slowing down. What can you comment on this segment in 2024?

Jesse Huang: We think it would be flattish YoY in 2024.

Q – Stanley Wang: We see more of your customers placing orders at foundries in China. What is the competition from China OSATs?

S.J. Cheng: We remain committed to investing in R&D and developing core technologies to meet customers’ evolving requirements while enhancing our competitiveness and business strength. And we will continue to improve our quality, operational competitiveness, and expand the penetration rate of high-end products such as OLED, automotive panels, and high-end TVs to maintain our Company's competitive advantage. We also expect to benefit from a higher quality level requirement for European and American end brands.

Q – Stanley Wang: Is there any plan for high end tester capacity expansion in 2024?

S.J. Cheng: Regarding to the new DDIC high end tester capacity, it will be based on further customer demand and UT level in support of our customers as we drive strong free cash flow and maintain our competitive advantage and strength.

Operator: Thank you. And I am not showing any further questions in the queue. I would like to turn the call backover to G.S. Shen.

G.S. Shen: That concludes our question-and-answer session. Thank you for participating. I’ll turn the floor back to Mr. S.J. Cheng for any closing comments.

S.J. Cheng: Thank you everyone for joining our conference call. Please email our IR Team if you have any more questions. We appreciate your support. Goodbye.
