Hello, everyone. I would like to share with you the 2022 earnings. Last year, POSCO Holdings saw a consolidated revenue of KRW 84.75 trillion, up 11% Y-o-Y, with operating profit down by 47% at KRW 4.85 trillion. This is believed to be due to the flood impact of Pohang steel mills last September, which brought about suspended operation and associated costs, having an impact of some KRW 1.3 trillion on our OP. Added to that was the steel sector's rapid downturn from second half last year, which resulted in KRW 425 billion deficit in OP in Q4. However, the Green Materials businesses centered on secondary battery materials showed Y-o-Y growth in annual revenue and OP up 62% and 27%, respectively, driven by a good performance of the Energy business. The green infra business also saw a 27% increase Y-o-Y. POSCO Holdings since transitioning to a holding company structure last March has made strenuous efforts to promote new growth business and streamline our business portfolio. So if you look on Page 5, so you can see a graph of the CapEx in steel and non-steel business. So we increased our CapEx in non-steel business, primarily secondary battery materials and energy, which amounted to KRW 3.1 trillion. So 47% of total CapEx was allocated to a new growth business. So driven by such investment, the non-steel business profits grew 27% Y-o-Y, reaching up to 35% of the total OP. So the non-steel business has reached up to KRW 69 trillion. Moreover, there is the lithium brine plant in Argentina, SNNC nickel matte plant and POSCO high nickel refinery, which have been constructed. So the secondary battery materials business is conducted as planned. To produce black mass for recycling, we completed the construction and the permit of PLSC, and it began production. And the POSCO HY Clean Metal construction has been completed with permit underway. Once POSCO HY Clean Metal began production, this means that POSCO Holdings will commercially produce for the first time, core materials, including lithium. Our investment goes beyond secondary battery with the merger of POSCO International and Energy. New entity was launched in the bidding of this year, which will drive the energy business. We also have integrated logistics at the group level through restructuring and improved efficiency. Before I go into business performance by major areas, let me share with you 3 major business activities in 2022. So looking at Page 6. First is recovery status or recovery completion of Pohang mills. Our -- I'm sure that many of you were concerned. Our mills operations had been suspended, but have now fully normalized at our 17 mills as of January 20, and there is also #1 plate mill with lower efficiency due to small size of 600,000 tonne capacity. We decided to completely close it down. So we believe that the impact from natural disasters should not occur. That is why we are trying to improve our logistics as well. So the flood impact on our earnings is about KRW 1.34 trillion. That is KRW 904.5 billion in Q4. As mentioned in Q3, there was no additional inventory impairment loss. Recovery costs are estimated to be KRW 288.4 billion. Non-OP loss, including impairment loss and tangible assets, stood at [ KRW 235 million ]. The insurance settlement process is still ongoing. We received partial insurance payments. So this will go on, and we can expect more additional compensations. In Q1, we believe there could be additional recovery costs and its impact on earnings, but the level will be significantly lower than Q4. Now moving on to Page 7. Second is about the completed construction of PLSC and POSCO HY Clean Metal. As you may well know, our company is implementing a used better recycling business. The construction of PLSC in Poland was completed last August. We acquired business permit for waste disposal and treatment at the end of last year, and production has actually begun. And PLSC can produce 8,000 tonnes of black mass per year, and this black mass will be delivered in total quantity to POSCO HY Clean Metal at Gwangyang to be used in the lines. If you look on the right, there is POSCO HY Clean Metal image, and we have built the #1 plant on a land of 60,000 square meters and is currently in the commissioning phase. The CapEx for this plant was KRW 215.2 billion. And lithium, nickel, cobalt, manganese, that is total of 7 materials, can be extracted. So sometime around February this year, we'll obtain the business permits. And if that becomes possible in the second quarter, we'll be able to go for initial production. The produce is goods, we'll additional certification from precursor, cathode, and anode firms, including POSCO Chemical. And as for lithium, we have to get certification from battery makers, and we really want to shorten the certification period as much as possible so that we can start producing certified goods from mid-September and reach normal capacity by the end of this year. And even before certification, the goods can be sold as general materials. And we expect that from Q3, we'll be able to recognize sales, although in small amounts. So once we reach normal capacity, annual sales is expected around KRW 3,300 billion. So now moving on to Page 8. The recycling strategy at POSCO Holdings are 2 tracks. First, with green policies promoting stronger regulations on the use of recycled materials and secondary battery starting from Europe. There is indeed a growing need to develop partnerships for more competitive and stable recycling, and there is also a need to develop this type of partnerships. And as you may well know, we can recycle cell maker scraps and OEMs' used batteries as raw materials and then ultimately transform them into cathode, a precursor materials at POSCO Chemical for resupply. So this allows us to implement a closed loop. And we believe that, that is indeed a competitive edge. And the second recycling strategy is that with IRA in the U.S. and battery passport system in EU. There is a growing localization and demand for a supply chain of secondary battery materials. So building on our recent experience, we will work towards implementing localization by region in the long-run with cell makers and OEM players. On the next page, you can see a brief outline of our recycling process, and there might be some investors who have taken a trip there. If you look at our recycling plants, it consists of pipes totaling 5.7 kilometers in length, along with over 700 tanks, installed row-on-row. Through this, we can ensure a continuous flow of production, meaning that we can expect to see a recovery rate of over 95% for our black mass, nickel and cobalt. The process has also been designed to ensure a recovery rate of 85% of battery-grade lithium. This is quite competitive in our opinion. And for longer-term efficiency, we have also invested in process automation. The chart that you see on the right-hand side shows a process that is still under a development, and it is currently in the R&D stage. It involves an automated pretreatment process that allows for mass production without the need for dismantling and discharging, and it will also have a more simplified downstream process. So you can see that we will continue to invest in R&D and technological development, continue to accumulate our experiences and operate in commercialized plans so that we can see visible progress. Thirdly, on Page 10, you would see that we can now report that the merger of POSCO International and POSCO Energy has been completed as of January. This newly-integrated corporation will consolidate the value chain for all of the energy businesses of POSCO Group, allowing us to execute our green energy strategy in earnest. As the Energy business grows, we believe that this will give us more of a competitive edge as we transition our Steel business to eco-friendly green steel. The market cap of the integrated POSCO International is KRW 4.2 trillion, and this means that the equity stake of POSCO Holdings has increased from 62.9% to 70.7%. Next, allow me to deep dive into the earnings for each sector on Page 12 for POSCO. You will see that production and sales have decreased year-on-year due to the shutdown of the Pohang plant. You will see that the impact to profit was larger than the decrease in production and sales, and the reason for this is due to the product mix. We have repaired the facilities in turn, but we were unable to produce finished products in the fourth quarter and instead had to ship semi-finished products that have a lower unit price and less added value. So if you look at the sales mix on the bottom right, you'll see that the sales of slab increased substantially in the fourth quarter. Whereas the higher-priced STS in plates, which are produced out of our Pohang plants, have seen a decrease in sales. Together with fixed costs, this has impacted our sales mix and therefore impacted our bottom line. Next page. Even without the impact from the flood, the overall weakness in the steel market became more pronounced in 4Q. Sales price of carbon steel peaked in the second quarter, and 4Q sales price declined 13% compared to the third quarter. And on a month-to-month basis, the sales volume for December was the lowest. The combined losses stemming from the flood and from the overall market downturn has led to POSCO going into the red in the fourth quarter, finishing the year with an operating income of KRW 2.295 trillion. For overseas steel subsidiaries, they saw a profit of KRW 474 billion in 2022. But on a quarterly basis, the slow global steel demand edged these subsidiaries to turn to loss as of the fourth quarter. In particular, Indonesia, PT Krakatau and Maharashtra in India saw a further decline in 4Q. However, what's interesting is that our Chinese subsidiary, Zhangjiagang STS; and the Vietnam subsidiary, PY VINA, saw an improvement in the fourth quarter compared to 3Q. Next, moving on to POSCO International. POSCO International saw its highest revenue and profit ever recorded last year. Its 4Q operating profit also grew 21% year-on-year. The Myanmar gas field have performed quite well. I'm sure most of our investors are aware of this. And the Senex Australia subsidiary, which we acquired in April, also returned an operating profit of 21% since our acquisition to contribute to the earnings increase. On the next page, you would see POSCO Energy, which also performed very well. Revenue and operating profit in 2022, increasing 88% and 33%, respectively, benefiting from the rise in LNG prices and the expansion in its LNG sales and connecting business, making use of its own tanks. Going forward, the merger would lead to consolidated earnings, and this means that we'll see KRW 41.6 trillion, and this means that we will see combined earnings together going beyond, surpassing the KRW 1 trillion mark. As for POSCO E&C, they've recorded a profit of KRW 308.6 billion. Its profits have been shrinking due to the downturn in the construction industry and hike in the price, but managed to record a net positive OP for the fourth quarter as well to the tune of KRW 21.8 billion. POSCO E&C is maintaining a stable business by preemptively shoring up cash reserves and downsizing risks. For POSCO Chemical, it saw revenue of KRW 3.3 trillion and OP of KRW 165.9 billion. Last year was meaningful for POSCO Chemical as it was the first year when revenues from our new business, such as cathodes and anodes exceeded those of the existing products such as refractories and quicklime/chemical. Profitability declined in 4Q due to such imbalanced factors, such as the price of lithium inventory and changes in exchange rate as well as the flooding of the Pohang plant, which led to slower sales of refractories and quicklime. In 2023, this year, our revenue target has been set for KRW 86 trillion. Due to our aggressive planned investments into commercialization of the plant's producing materials for rechargeable cells, such as cathodes, anodes, lithium and nickel. Our CapEx is expected to increase to KRW 11 trillion year-on-year. However, within this budget, we will -- although we have this budget set aside, this doesn't mean that they are all slated for execution because our thinking is that we will quickly greenlight those investments that can ensure future growth while downsizing or even delaying the investments that are not as urgent. So we will be selective in pursuing these investments from the perspective of our entire business portfolio. And this will conclude my earnings presentation. Move to Q&A.
