Thank you very much. Very welcome to our presentation of our Q4 and full year 2020 results. Page three, please. I would just like to make a brief overview of who we are for those of you who might not know us so well yet. We are a global provider of premium indoor air cleaning solutions. The main markets that we operate in are the Northern and Central Europe, Japan, and the U.S. Traditionally, we've been addressing customer segments within logistics, industry, food, offices, and clean room segments. We have more than 2,500 customers worldwide, and we have more than 9,500 installations. We work with long-term rental contracts that typically run over 36 months, and we have satisfied customers. 75% of our contracts are either extended or renewed. Next page, please. Page five, please. Looking at the key financial highlights for Q4, we deliver improved margins and increased recurring revenues. Sales in the fourth quarter were affected by corona, and we saw a currency-adjusted decline of 8.7%, and that is also comparing to a very strong Q4 in 2019. We saw an increase in our installed base, which is the base for our revenue generation. We saw an increase of 14%. Our recurring revenues in the quarter increased by 25% to SEK 64.6 million. On our order intake, we saw a negative impact from corona, and we saw a decline by 35% to SEK 66.7 million. However, we saw a strong increase in shorter rental contracts that are not included in our order intake statistics. We also had a very strong Q4 2019 in Japan on our order intake side because of the implementation of the Health Promotion Act from the 1st of April 2020. We delivered an increase in EBIT margin, and it was at 19.3% and SEK 20.5 million. The board proposes to pay out a dividend of SEK 1.3 per share. Page six, please. 2020 was the year when we saw a significant increase in the awareness of the importance of indoor air quality and an understanding that air cleaning solutions can contribute in a positive way to provide healthier indoor environments. Quickly during the outbreak of corona, we moved into a mode of putting solutions in the marketplace to provide healthier indoor environments. In a first step, we reinvented ourselves and based ourselves on our existing current solutions. We launched an execution of our FS 70 with FS 70 HEPA and an Air cleaner HEPA. We also started a product development initiative to understand and work closely with the healthcare sector and understand what type of solutions would be optimal to help the healthcare sector to provide more safe and secure working environments. Through that work, towards the end of Q4, we launched our newest innovation, the FS 30 HEPA product, a quiet air cleaner, powerful, and that is adapted to the healthcare sector, but also public places and offices. Page seven, please. During 2020, we have had a record year in bringing new products and innovations to the marketplace within our Facility Solutions. When we started 2020, we had two products. We had the Air Cleaner 115, and we had the FS 70. Step by step, we have extended and broadened our product offering. First of all, we have been sticking to the plan we had at the beginning of the year, that was to introduce a product specific for the food segment, our FS 70 Food Grade product that we launched in Q2. Towards the end of Q3, we introduced the FS 90, where we target larger industrial areas. We maintained the plan we had disregarding the turbulence that happened out of the corona. In addition to that, we launched a number of new applications targeting the need to provide more safe and secure working environments. We leave 2020 and enter 2021 with a significantly increased and extended product portfolio. The product portfolio that is broader than it had been had not corona happened. Page eight, please. With this extended and improved product portfolio, we also see the result in the increase in order intake. In Q4, we had a number of breakthroughs. We received the biggest order to date when it comes to our Facility Solutions, and that was for the school sector in Germany, where we obtained an order worth EUR 500,000 approximately. We continue to develop and deliver to the healthcare sector. Moving into 2021, we continue to see the positive impact from our expanded product portfolio by getting orders for our new product for our company in Japan, and we also gained a second large order for the school sector in Germany. Page nine, please. I would like to highlight a couple of customer cases where we provide more safe and secure working environments in different customer segments. The first one being the healthcare segment and the customer being Karolinska University Hospital, where they, during the outbreak of Corona, understood an urgent need to improve the working environment and reduce the virus concentration in their premises. They asked for our support and help to provide a more safe and secure working environment. So far, we have delivered 90 air cleaners to Karolinska University Hospital, and we have also continued our strong and close cooperation when it comes to innovation. Next page, please. Another example of where we contribute to providing more safe and secure working environments, and where we can also contribute to making sure schools can remain open and society can remain open, is that within Germany, there has been a very strong focus from local government to subsidize investments in air cleaning, because a number of prominent sources like Technische Universität in Berlin and the Robert Koch Institute are highlighting that air cleaning with HEPA 14 filters can be an efficient means to reduce virus, bacteria, and other contaminants concentration. We have delivered step-by-step air cleaners to the schools worth EUR 1 million in order value. We will continue to do that during Q1 here. Page 11, please. Another example where we contribute to providing more safe and secure working environments is towards the office segment and in Japan. Traditionally, we have a very strong position towards the office segment in Japan through our Cabin Solutions. One example of such a customer is Yostar, a Tokyo-based gaming company that realized during the outbreak of Corona the need to improve the air quality in their offices in order to take care of their personnel. Since they were happy with our Cabin Solutions product since before, it became natural for them to turn towards us and have us deliver air cleaning solutions. They have purchased a large number of Air Qlean Low products. Next page, please. Page 12. To wrap up on Facility Solutions, we have broadened and expanded our offering during 2020, and during Q4, we start gaining groundbreaking big orders for these new solutions. They will help us to drive growth going into 2021. We continue to see growth opportunities within our core traditional segments of industry, logistics and food, and we have increased our offering towards these segments during 2020. We are developing new markets in terms of geography with our introduction in Japan and within our customer segments. That has also resulted in a strong increase in order take for shorter contracts. We saw in the quarter an increase in our sales performance of 11% compared to the same quarter last year. Average over the last five years, we deliver an average annual growth of 18%. Page 13, please. Looking at Cabin Solutions, 2020 was our best year ever, and we delivered a sales level of 393 million SEK, representing an average annual growth of the five last years of 9%, and the growth this year of 9.5%. We had an exceptionally strong Q4 and first half of the year 2020 in Japan because of the implementation of the new Health Promotion Act. In that respect, we saw a decline compared to Q4 2019. It was the biggest and strongest sales performance to date when it comes to Cabin Solutions. Next page, please. Page 14. When it comes to Room Solutions, our primary market is the U.S. Our customer segments in the U.S. are pharmacies within the hospital systems and independent compounding pharmacies. They have been largely impacted by Corona. We have seen longer decision processes within our customers when it comes to investments. We entered 2020 with a very strong pipeline. We see only a minor decline in our sales level compared to 2019. We ended at SEK 54 million compared to SEK 56 million in 2019. We had a weak quarter in Q4, and we had challenges on the order intake side. However, the year ended with the biggest order to date when it comes to Room Solutions, and we received an order of approximately $1 million US dollars in value, ending 2020 in an upward trend also in the U.S. Next page, please. This is breaking new ground number two, this large cleanroom of $1 million US dollars that we received an order for at the end of December, and that we will start implementing as of Q1 2021. Here the need from the customer of what the cleanroom, which is compliant with USP 797 and USP 800, and they also needed a flexible solution so that they could continue with their compounding operations while the new cleanroom is being built. There our modular flexible solution works very well for this customer. This is cleanroom number six for this U.S. university hospital system. It is a very satisfied customer. Next page, please, page 16. To summarize in a business perspective, we have maintained a high activity level. We have introduced more solutions and products than ever before. We have obtained a number of groundbreaking business opportunities, and we have developed new customer segments. I'd just like to highlight our business model and performance during 2020. It is our installed base that drive our sales. We saw an increase during 2020 of 14% of our installed base. However, when it comes to our order intake of our long-term rental contracts and the direct sales of products to customers, we saw a decline compared to last year because of the COVID situation. However, at the same time, we saw a sharp increase in the number of shorter contracts, which are not included in the order intake statistics. That increase was of 492% or 231 units. When it comes to our sales mix, we saw an increase in our recurring revenue of 35% during the year, landing at SEK 259 million. We saw a decline in our sales through finance companies, we ended up at SEK 130 million, we saw an increase in our product sales and ended up at SEK 104 million. In total, sales were up by 9%. When it comes to our increase in recurring revenues, one explanation for this is the acquisition of SFS Finance in December 2019. We have increased the book value in units in our own balance sheet to SEK 46.4 million from a level of SEK 23.6 million in 2018. We have consequently increased our investment in our books of SEK 22.8 million. At the same time, we have seen an increase in our recurring revenue from SEK 164.8 million in 2018 to SEK 258.7 million in 2020. That's an increase of SEK 93.9 million in recurring revenues. An investment of SEK 22.8 towards an increase in revenue of SEK 93.9 million. We increased our recurring revenues to 52% compared to 41% of our total sales. Next page, please. Page 17. Our installed units gives us visibility into 2021. Our recurring revenues that come from our own units in our balance sheet. Both our own contracts and contracts with finance companies typically run for three years, and more than 75% of the contracts are extended or renewed. That means that also for our contracts through finance companies, we have an element of recurring revenues because after three years, they are most often renewed. We also have a recurring element from our service and maintenance income. We have good visibility when it comes to when contracts will expire, so we can address and work proactively on maintaining and increasing our installed base. Next page, please, page 18. Prior to releasing our report, we also released a press release about how much clean air we deliver, and that is a natural consequence of our installed base. The higher our installed base is, the more clean air we deliver. We delivered at the end of 2020, a figure of 9.77 numbers of the Globe Arena per hour of clean air, and that was up by 13%. In short, we have had challenges in our fourth quarter when it comes to our order intake, and we have been negatively impacted by Corona on our sales level. We also have seen the positive effects of our significantly extended and broadened product offering in facility, gaining good traction in terms of order intake in Q4. We have a resilient business model, which serves us well during challenging times like Corona, where our increase in installed base and our increase in recurring revenues is comforting. We have maintained during 2020 a high activity level in the organization. Then I'd like to take the opportunity and thank the fantastic team at QleanAir for all the contributions and the dedication and passion to make this happen. Then I'd like to hand over to our CFO, Henrik Resmark. Thank you very much, Christina. Moving into the financial information, please move to page 20, please. The recurring revenues are increasing full year 2020, flat 35%. We have an increase of installed units with 14% and more than 75% of our long-term rental contracts are either renewed or extended. It is very clear that QleanAir has a satisfied customer base. Page 21, please. As mentioned, order intake is down by 35% and sales is down by 9% versus fourth quarter 2019. We are a growth company. We are launching new products, and hence, we need to meet our new customers to be able to sell. A large part of the market in Europe and the U.S. have been closed or have had restrictions, also Japan to some extent. Comparing fourth quarter with the third quarter 2020, we see an increase in order intake and revenues. That is a positive sign. In full year 2020, we deliver a growth of 9% in a year that we have had tough market conditions for most of the year. Again, our installed base are driving our long-term revenues. Page 22, please. In fourth quarter and full year 2020, EBITDA and EBIT improved in absolute numbers and also the margins. EBIT margin was 19.3%. We have an efficient business model, meaning when sales are not developing according to plan, we have the opportunity to defend the margins in combination with continuous cost control. Full year, the recurring revenues are up, and the cash flow is improved. Profit per share was SEK 4.51. Moving to page 23, please. On this page, I would like to highlight first the equity ratio improved to 27%, up from 16%. Net debt reduced to SEK 199 million, down from SEK 237 million. We have a clear strategy to reduce the net debt over time according to scheduled amortization. Operative cash flow of SEK 20 million, up from SEK 10 million. Improved cash flow and the business model is efficient also in challenging markets. Cash generative business model and strategy to pay dividends to shareholders. Dividend of SEK 1.30 per share is proposed by the board. Having said this, I hand over to Christina again. Thank you. I am very pleased to conclude that for a year like 2020, we managed to reach our financial targets. When it comes to organic sales growth, we have an average annual growth target of approximately 10%, and we achieved 9%. We have a profitability target of 15%-20% of EBIT margin. We delivered 19.3%. We have a policy to pay out 30%-50% of our net profit in dividends. That is in line with the proposal from the board of paying out 1.30 SEK. I'm very pleased that we, in challenging times, managed to obtain our targets. To summarize QleanAir as an investment on the next page. We have a unique service offering based on a holistic approach to QleanAir as a service with full-service rental contracts. We have proprietary air cleaning technology and back office solutions providing substantial barriers to entry. We have long contracts with a high degree of extensions across a diversified blue-chip customer base, generating strong and predictable revenue. We have an asset-light business model with limited CapEx needs, providing strong free cash conversion and equity returns. I would like to hand over for the Q&A session. Thank you. Ladies and gentlemen, if you do wish to ask a question, please press zero one on your telephone keypad now. That is zero one to register for a question. We have a question from the line of Anders Roslund from Pareto Securities. Please go ahead. Yes, good morning. I would like to know a little of how 2021 will look like. You will obviously start with some negative sales growth versus a very strong Japanese development in the first and second quarter. I assume that you also expect a stronger growth specifically in Facility Solutions and maybe also in Room Solutions. How do you see 2021 looking like? Yes. We see a little bit of a mixed picture. We have still in Q1 2021, a challenging situation with COVID with continued lockdowns in many parts of the world. For us, it is important to have access to open markets and conduct critical meetings and so on. That is one challenge. As we have described with our extended and deepened product offering, we see continued possibilities to grow in Facility Solutions and equally in Room Solutions, a growth area for QleanAir. It's a little bit of a mixed picture. Yeah. If we just elaborate a little bit more on the growth areas at Facility Solutions, we have seen several large orders, and I assume there will be some minor orders as well. If you look at the installed base, the installed base is developing much more favorable than your order intake, showing clearly that you have a larger share of your installed base with shorter contracts, probably in the facility area, while you have less of long-term contracts. The first part of your question is that, yes, we see a continuous order intake, we only go with press release on the larger, of course. Yes, the installed base is positively affected by also short-term contracts, and that is the total installed base globally. That again is driving the top line, of course. The order intake isn't the full order intake from that perspective as we have described earlier, and that is the reason why you see that difference. We've seen very positive comments from the Facility Solutions area. You have only got one large order in Room Solutions. How do you see the Room Solutions area developing in this year? This was an exceptionally high value, the Room Solutions order that was announced in December. Of course, we don't announce all orders in our ongoing business. I would refer a little bit to what I said before that 2021, going into that year, we still have the COVID situation, and that is part of the reality also in the U.S. We see a very good underlying growth opportunity within our Room Solutions business going forward. Absolutely i t's more short-term related to COVID uncertainties, but the underlying potential is not changed when it comes to Room Solutions. Yes, the Room Solutions area will be more affected by the close downs and tough conditions for the healthcare sector in the U.S. That's what you're saying? We have continued in 2020 to proceed with our installations. We deliver a 2020 that is almost in line with 2019. We have been able to navigate and maneuver there also in a challenging year of 2020. What we have seen is somewhat longer decision processes at the customer side, which had an impact on the order intake side. Finally coming back to Cabin Solutions. What is the new normal in Japan now? Since a very strong surge up to the second quarter, what do you think will be the new normal in Japan? In the short term, also Japan is affected by Corona, and we have seen a shutdown situation also here during the second wave of Corona in Japan. Short term, we see that impact also for Cabin Solutions in Japan. As we have outlined, the first half of 2020 was very strong based on some fantastic opportunities, and we don't see those one-time opportunities reoccurring in 2021. We still see a strong opportunity for us to continue to develop our Cabin Solutions business in Japan and grow in the medium to longer term. In Cabin Solutions, how do you see the development in Europe? In Europe, we see a more mature market when it comes to Cabin Solutions, but more mature and stable. It's more in Japan that we have the growth opportunities within Cabin Solutions. Excellent. What do you expect when it comes to new products? You introduced several new products now last year in Facility Solutions. Are there any news on that respect for this year? We will present product news when we are getting closer to launching them, but we will continue to have a high focus on innovation and bringing new solutions to the marketplace. That is part of our DNA and will continue to be so. Regarding markets, you remain on the present market structure. You open up sales of Facility Solutions in Japan. That was presented last year. Is that the new launch you have in market respect? Yes, that is a very important step for us. We have been very successful in our Cabin Solutions business during many years in Japan, and we have a very strong customer base with our office segment, and that is a segment where also Facility Solutions are very relevant and especially so with the corona situation. We have been able to extend our offering to our current customer base. Step by step, we will implement our whole facility range in Japan as well. That is something going on gradually during this year? Yes. Okay. That's all the questions from my part. Thank you. Thank you, Anders. I remind you that if you want to ask a question, please press zero one on your telephone keypad now. There are no further questions at this time. Please go ahead, speakers. Thank you very much.
