Operator
operatorWelcome to Solvay's Full Year 2021 Results Conference Call for Analysts and Investors. Solvay team, the floor is yours.
Jodi Allen
executiveGood afternoon, and welcome to our fourth quarter 2021 earnings call. My name is Jodi Allen, and I'm joined virtually by our CEO, Ilham Kadri; our CFO, Karim Hajjar. And today, we are also joined by Philippe Kehren, President of Solvay's Soda Ash & Derivatives business. Today's call is being recorded and will be made available for replay on the Investor Relations section of our website shortly after the webcast has concluded. I would like to remind all participants that the presentation includes forward-looking statements, which are subject to risks and uncertainties. You may refer to the slides related to today's broadcast, which are available on our website. With that, I'll turn the call over to Ilham.
Ilham Kadri
executiveJodi, and hello, everyone. I'll begin my remarks, as usual, with the health and safety overview shown on Slide 3. As of last week, we have 158 colleagues who are infected with COVID-19. The number of confirmed cases is down significantly from a peak of 430 on January 20. [Technical Difficulty]
Jodi Allen
executiveHello, operator?
Operator
operatorHello, I think we have a technical issue, we have no more sound.
Jodi Allen
executiveOkay. Can you ask everyone to bear with us, please, for a few minutes while we resolve the issue.
Operator
operatorYes, everyone is hearing you. So ladies and gentlemen, please wait a few minutes. The conference will begin again.
Ilham Kadri
executiveThe impact of the Omicron variant was particularly apparent in the Solvay workforce in the United States of America, Italy and France over quarter 4 and into the new year. Although the number of cases continues to drop across the company, we must remain vigilant as we gradually and carefully look to reopen our administrative sites with measures in place to protect our employees and their communities. We will continue to work in a hybrid mode as pandemic control measures ease. On top of that, we will continue to use the Solvay Solidarity Fund and have used for EUR 6.4 million out of the EUR 15 million collected from investors, management team and directors' donations to support our people and communities in 13 countries around the world. And this leads me to our sustainability program, Solvay One Planet, which is an integral part of our strategy. I would like to celebrate some of our achievements in 2021, which are shown on Slide 4. As you know, Solvay's fully committed to reducing carbon emissions. Here, you see that we continue to make excellent progress against our targets. The impact of the pandemic on 2020 activity level is well known, so the increase in emissions in 2021 comes as no surprise. But what is most significant is the fact that we have achieved an 11% reduction across the 3-year period, which means we are surpassing our targets to be aligned with the Paris Agreement's 6.6% cumulatively very substantially. Last quarter, we announced our ambition to reach carbon neutrality before 2040 in all businesses and before 2050 soda ash. We are accelerating our efforts in this area by announcing today another major project to transition to cleaner energy in our largest soda ash plant in Devnya, Bulgaria, and Philippe will give you more details shortly. Our climate efforts are getting recognized, and we were recently recognized by the rating agency, the Carbon Disclosure Project, or CDP, which upgraded Solvay from B to A-, and we are proud to be in this leadership band and higher than the chemical sector average of B. Slide 5 shows the summary of our ratings from various independent rating agencies. We have made many more achievements in our other two pillars, resources and better life, which we have highlighted in our quarter 4 earnings press release. As an example, in quarter 4, we announced the launch of our very first employee stock ownership plan, offering the employees the opportunity to buy shares at a 10% discount. We are very proud of the strong progress as we deliver on our ambitious road map. There is much more to do, and this remains a key priority for Solvay and is directly aligned with our company purpose and our strategy. Moving now to our full results shown on Slide 6. 2021 marks another great year of progress in our transformation journey. We're emerging stronger on all fronts, from pricing power to profitability, from cash generation to returns. I'm proud of the strong performance we delivered in the fourth quarter as we navigated new challenges facing the chemical industry and overcame these headwinds with necessary price actions to maintain and actually increase our margins. Our businesses continue to do an outstanding job managing an environment of inflationary pressures, supply chain constraints and lingering uncertainty due to what we hope are the last stages of the pandemic. Let me, here, extend a sincere thank you to our team globally for their continued hard work and unrelenting focus on serving our customers. Without you, we would not be in the strong position we are in coming out of the pandemic in 2020 and the year besieged with challenges in 2021. Comparing the fourth quarter of 2021 to the previous year quarter, sales were up 22% on an organic basis and up 17% versus the full year 2020. Of this 17%, 12% growth was from volumes, and 5% from pricing. We accelerated our pricing efforts in the third quarter and began to realize the benefits in quarter 4, achieving 12% growth from price increases. This is the highest single quarter level of price achievement in the past 5 years. Sales for the full year were up over 4% versus 2019 precrisis level, and this is without the full recovery, as you know, of the civil aero markets. Demand in all our key end markets was strong in quarter 4, with double-digit growth driven by automotive, agro and seed, electronic and consumer markets. Likewise, our full year 2021 sales performance exceeded market growth in the same core area. Geographically, all regions delivered double-digit organic sales growth versus quarter 4 2020. Europe was up by 14%. Asia Pacific, China up by 19%, and the rest of Asia up more than 30%. North America was up 22%, and Latin America was up by 33%. The double-digit top line growth and EUR 40 million of structural cost reduction resulted in strong EBITDA performance in the fourth quarter, up 24% organically. For full year 2021, Solvay reported a record EBITDA of EUR 2.35 billion, up 27% organically versus 2020 despite the higher inflationary environment and unfavorable energy headwinds. We also surpassed 2019 EBITDA levels by 8%, twice the top line growth, demonstrating strong operating leverage, and this is the result of volume, our accelerated pricing initiatives and ongoing restructuring and cost takeout measures. We're also marking the achievement of a new milestone, namely delivering returns of 11.4% in 2021. Remember back in 2019, when we first launched our G.R.O.W. strategy, the return on capital employed was 8.1%, and we committed to exceed 11% by 2024. The strength of our operational performance, combined with the optimization and rationalization of our assets and pruning of some product lines, enables us to deliver on this target 3 years ahead of plan. Last but not least, we continue to deliver strong cash performance. As you are likely aware, we laid the foundation back in 2019 when we put in place a new incentive structure and more focused and disciplined governance. You saw us accelerate our delivery during the pandemic, and we have continued to deliver. This is, in fact, the 11th consecutive quarter of positive free cash flow generation. Why this is important? Because our strong cash generation enables us to invest for the future, and we have a number of exciting growth opportunities, thanks to our customers who value our sustainability-driven innovation and come to us with even more opportunities. So speaking now about investments, as you have witnessed, following our batteries webinar a few weeks ago, we are switching gears from getting fit to changing the game through the acceleration of our investments. In batteries, we are investing EUR 300 million in the next 2 years in Tavaux, France. I encourage you to listen to the webcast replay available on our website to learn more about our ambitions and targets in the auto and batteries market. In addition, just this week, we announced new investments that affirm our #1 leading position in the U.S. sulfone polymer market. We are increasing the capacity of polymers, such as PSU, PESU, and PPSU, which serve growth in various markets, including health care, water purification and food industries. Finally, similar to the auto webinar, I plan to host other dedicated webinars throughout this year, either a stand-alone events or a spotlight topic during our earning calls. The objective of this webinar is to introduce some of our global business units' presidents and other experts and leaders in order to share more about their businesses' strategies and performance highlights and to help address the many good questions you have. So today, I'm very pleased to be joined here physically, actually in Brussels, by the President of our Soda Ash & Derivatives business, Philippe Kehren. Philippe has been with the company for 26 years and has accumulated a wide range of experiences, from finance, managing energy and clean energy production to leading transformation projects and customer relations in the Europe, Middle East and Africa region. In the fall of 2020, he accepted to become the President of the Global Soda Ash & Derivatives business where he and his team have been driving the business transformation flawlessly on both the operations and sustainability fronts. Philippe will now give you an overview of the soda ash business and current market environment. Happy to have you here, Philippe. Now I'll turn the floor to you.
Philippe Kehren
executiveThank you very much, Ilham, and hello, everyone. Very happy to be here as well. Well, since taking this role, the objectives of this business have been crystal clear to me: to focus on cost competitiveness and sustainability and to continue to drive cash generation. We have also leveraged the transformation done at group level to build a leaner and fit-for-purpose organization for our business. Now today I would like to share with you an overview of our markets. I'll discuss the pricing environment and contract status for 2022. We will also take a look at our world-class assets and leading cost position, and I'll update you on the step changes we are making with our energy transition projects. So what is Soda Ash & Derivatives at Solvay? Our business has annual sales of EUR 1.5 billion. We operate in 11 production sites globally: 9 are producing soda ash and bicarbonates, and 2 are producing raw materials. And we have 3,200 employees. And we serve customers everywhere in the world. Now let's start with our markets. Soda ash and sodium bicarbonates are considered as essential chemicals that serve resilient and growing end markets. There is a large number of diversified markets for these chemicals. By far, the largest market is still for glass manufacturing. About 50% of our soda ash sales today are used in glass for building, automotive, food and beverage containers and also for new growing applications, such as photovoltaic panels. About 25% of our soda ash is used as a water softener for detergents. It's also used in various industrial applications and also in new applications that are developing, such as lithium carbonate for batteries. And of course, we also use soda ash to produce sodium bicarbonate ourselves, which we have branded as Bicar. Bicar represents 25% of our sales, mainly serving 4 markets: flue gas treatment with our SOLVAir solution and also feed, food and pharma. These markets are backed by single sustainable megatrends, including resource efficiency, for example, the need for double-glazed windows to improve energy efficiency and other drivers like recyclable packaging. For example, its use in glass containers supports the reduction in use of single-use packaging. Another trend is emission control, where, for example, our SOLVAir-branded sodium bicarbonate is used flue gas treatment to clean air. And we have even developed very recently a solution for ships to depollute their exhaust gas. Most of our markets have been resilient through the COVID-19 pandemic. And in fact, today's demand is back at pre-COVID sales levels. Our markets are expected to grow by 2% per year for soda ash and 4% per year for sodium bicarbonate. Now let's move to our business environment, pricing and contracts. So on Slide 10, on the left chart, you have a good overview of the evolution of market demand and pricing dynamics of this business over the past 5 years. The chart on the right shows the evolution of our profits through the same time period using normalized data. What you can clearly see is the demand reduction in 2020 and then, as volumes recovered in 2021, the margin squeeze that occurred during 2021 as a result of the significant cost inflation impacting the business, first, on sea freight and then, starting in the summer of 2021, on the energy markets, in particular, in Western Europe. Despite the margin squeeze that had a significant impact on our EBITDA, we have been able to deliver a strong cash performance, thanks to a strict discipline on fixed costs, thanks to a very tight asset management and also thanks to a very strong working capital management. And for the first time in our history, we've been able to renegotiate conditions on fixed price contracts. And I take this opportunity to thank our customers who supported us during these unprecedented times. We have not been able to fully offset all the extra costs, but this allowed us to continue to safely supply them and to move forward with our energy transition investments. As most of you are well aware, the majority of our contracts are negotiated annually, and we've just completed our 2022 negotiations. I'm pleased to report that our negotiations for 2022 have been successful, better than the market average. For your reference, the latest public data published by analysts, such as IHS, indicates an average pricing that increased by 27% in Europe and by more than 50% on the export markets and then that some surcharge closes have been introduced to face this unprecedented cost situation on logistics and energy. Given the surge in energy costs in late 2021, it was critical for Solvay to increase pricing in order to manage the strong cost inflation, of course, but beyond that, to recover pre-COVID profitability levels. This is absolutely needed to support the investments that are required to execute our energy transition and to be able to invest in capacities that are needed by our customers. Now let's move to our assets and our cost position. Solvay is a global leader in soda ash operating world-class assets. On the chart of Slide 11, you can see the cost-merit curve of the industry on an FOB basis, meaning the cash cost to bring the product to the nearest harbor. Our synthetic and natural soda ash sites are highly competitive, with 75% of our capacity in the first quartile of the industry cost curve, which you can see here on the chart. These world-class sites are able to serve any customer anywhere in the world. The remainder of our assets, so-called regional assets, are the most competitive in their regional markets. They are not designed to export. So the FOB cost to the nearest spot is not relevant for them, but they offer local, competitive and secure supply to our customers there, and they are better positioned than the world assets, as you can see in top right corner. This competitive position takes a continuous and focused effort by our entire business and all the teams. We've been relentless in finding ways to reduce process costs. And in fact, we have reduced costs by EUR 50 million in the last 2 years since I took the role, and we have reduced costs by about EUR 200 million in the past 10 years. This is how we maintain our leadership position. We have 6 synthetic plants Europe that are sustainable and competitive in the long run. Along with our natural soda ash unit in the U.S., this gives us a unique portfolio of assets in the market. Even though new developments will likely take place in the natural production of soda ash, synthetic production remains a critical source across the long term, given that there are not enough natural trona resources on the planet. On Bicar, we continue to consolidate our leadership position. We are producing Bicar at all of our soda ash plants, and we have 2 additional units only dedicated to Bicar in the U.S. and in Thailand. As a reminder, back in 2019, we announced an investment in our site in Bulgaria to build a new bicarbonate plant to meet the growing demand. I'm happy to share that we have completed this expansion, and the new capacity is now available. That is 15% additional capacity available for our customers. Finally, in order to make all our plants sustainable, it is absolutely key to do their energy transition. And we made significant progress in 2021 and very recently, and that will be the last part of my talk today. As part of Solvay One Planet sustainability road map, the soda ash business has committed to become carbon neutral before 2050 and to phase out coal 2030. We have already taken a number of steps in our European and U.S. plants to enable such a transition away from coal usage. In 2021, our site of Rheinberg in Germany began the process of switching from coal to using biomass derived from waste wood chips. The first boiler has been operating since May 2021, and we approved the construction of the second one. Rheinberg is set to become the world's first soda ash plant powered primarily by renewable energy by 2025. Last week, we have officially announced that our site in Dombasle in France will exit coal completely and transition to 100% primarily refuse-derived fuel as early as 2024 to cut emissions by half. This is the first project of its kind in France. Those two projects will use local resources and develop a circular economy. Plans are also underway to transition our Green River, Wyoming plant from coal to gas in 2 stages to be completed by 2023. And today, we also announced the first step in our largest European site in Devnya, Bulgaria by converting a boiler to biomass. The biomass will come from a variety of sources, including locally sourced sunflower husk pellets. This boiler is projected to come on stream in November of this year. Today, as we speak, we have already cut our emissions by 5% versus 2018. By 2025, with the projects I just described, we will have achieved 20% emission reduction in our global business. And by 2030, we target a 30% reduction with more projects. As a reminder, each of these projects are economically profitable, and they further derisk our operations, in particular, by removing the exposure to the highly volatile fossil fuel markets. Beyond this, we plan to initiate new process innovations and other energy technologies to support the exit of coal in our hard-to-abate sites. The transformation is not only part of our sustainability ambition, but it is valuable to all stakeholders, our customers, our employees and our investors, and that's to keep our sights at the forefront of the industry in terms of reduced environmental impact and cost competitiveness. Thank you very much. Now back to you, Ilham.
Ilham Kadri
executiveThank you very much, Philippe. Really happy to have you with us today. And I just want to say great job to you and to your global team, who I know are listening to you today for not only the successful completion of your contracts, and I know you've done something historical by reopening them in quarter 4, but the exemplary way you are driving our cultural environment and an operation transformation. So now, ladies and gentlemen, I would like to pass the floor to Karim, who will -- as traditionally, will review in more detail the group segments and financial performance in the fourth quarter of 2021. Karim?
Karim Hajjar
executiveThank you, Ilham. Good morning, good afternoon, everybody. I'll start with an overview of the 3 business segments, and as usual, we'll refer to figures on an organic basis, which, I mean, at constant scope and currency. Beginning with materials on Slide 13. Sales in the segment increased 20.2% in Q4 as Specialty Polymers delivered yet another record quarter. Growth was, once again, driven by automotive, EV batteries and electronic markets, each with double-digit sales growth. The growth in auto, by which I include batteries, grew by 31% over the full year 2021, and we expect continued strong growth over the next decade and beyond as we shared with you with our -- in our recent auto batteries webcast later in the month. But that's not the only driver. Our polymers are adding real value in a number of key markets. Polymers sold in electronics sector grew 19%, boosted by semiconductors, electrical components and, of course, small devices. Sales grew by 11% in health care, which includes polymers used in medical devices and in pharmaceutical packaging. Our technologies are adding unique significant differentiated value. And as a result, we continue to win new business. Specialty Polymers is exiting the 3-year cycle 2019-2021 as a clear winner against our most formidable peers in high-performance polymers, be it PEEK, PTFE, PPA to name but a few. Turning to composites. We saw sales recover strongly from albeit low point of the pandemic in Q4 2020, with organic sales up 24%. Growth was driven by the increase in single-aisle aircraft production, for example, the Boeing 737 MAX, A320neo, the A220 aircraft as well. This grew 57% from the 2020 year low points. Sales for the space and the defense markets grew by 2% in Q4 as launch and other defense programs partially offset the reduction in -- the temporary reduction in the F-35 program build rates. For the full year, our civil aero business was down 11% versus 2020, and our space and defense sector grew by 8%. Solvay's diversified presence across multiple aero and defense platforms allows us to have less exposure to the softness -- to the weakness in twin-aisle widebody aircraft production rates. That's important. But it's also important to recognize and to note that the supply chain and the delivery constraints that we've experienced are continuing. They continue in this market, creates challenges based in raw materials, logistics and also in labor availability. Turning to profitability. The EBITDA of the materials segment increased 31.4% year-on-year, and our EBITDA margins improved almost 300 basis points to 27.5%, primarily due to record sales in Specialty Polymers and, of course, the benefits of price increases that have helped to offset inflationary cost pressures in both of our businesses. Now I'm going to turn to Slide 14 to review the solutions segment which, as you can see, delivered sales growth of 28% in the fourth quarter. Beginning with Novecare, sales were up 33% almost, thanks to both volumes and pricing driven by core markets, including agriculture, coating, home and personal care, each of those delivering double-digit growth. Oil & Gas, which is now reported separately as of the third quarter, was up by 88% in the fourth quarter, driven by strong pricing predominantly. The Aroma Performance business achieved record results in the fourth quarter, with sales growth approaching 37%, thanks to good demand across all product lines. In Special Chem, fourth quarter sales grew modestly by nearly 2%, driven by electronics, which partially offset lower sales to auto. Technology Solutions had another good quarter, with sales growth of 15.4%, driven by mining and by phosphorus derivatives. The wrap-up solution, the segment delivered 29% EBITDA organic growth compared to Q4 2020. And that reflects a strong and a continued recovery, together with our pricing, across most markets, while EBITDA margin rose modestly to 17%. Turning to chemicals on Slide 15. You've heard Philippe, but look at the whole segment, fourth quarter sales in the segment were up 18% with all businesses, all of them, experiencing organic growth year-on-year. Philippe has already covered soda ash business, so I won't go into that any further. Of course, we can take your questions. Peroxide sales were up organically 16.5% in Q4, driven by volumes and by price as market conditions remained strong in hydrogen peroxide for the merchant market as well as for the HPPO mega plants. The Silica business also performed well, with a 13% sales growth in the quarter, thanks to pricing initiatives. Now although tight demand is still slightly down compared to 2019 levels, demand remains strong for the specialty grades that the Silica business specializes in, and that's important. An example of the recent innovation, by the way, called TECHSYN, which you may recall is a result of a collaboration with some key partners, including Bridgestone. The Coatis business in Latin America continued its exceptional growth momentum, with fourth quarter sales up 59%, thanks to sustained demand in key markets and increased pricing power. The chemicals segment had very strong performance in the fourth quarter, with 37 -- well, nearly 37% growth in EBITDA, thanks to sales, volume growth and strong pricing management in each and every one of our businesses, supported again by exceptional performance in Coatis and indeed in RusVinyl. I'll now move to the group's financials on Slide #16. First, the significant inflationary cost headwinds that we flagged in Q2, you recall we mentioned EUR 200 million to EUR 250 million that we updated to around EUR 400 million at the beginning of November last year, well, the truth is we underestimated it. They came in at EUR 465 million for the full year 2021. To give you a bit more color, about 70% of the increase related directly to raw materials and energy and about the remainder related to logistics and packaging. That's the context against which we mobilized. We mobilized the whole of our organization starting in the third quarter because we really were determined to accelerate our price increase actions in order to respond, in order to really face those challenges head on because those cost pressures are very clear, and we're really proud of what the teams have accomplished truly. We've overcome a significant amount of those costs. We've kept our assets running safely to keep utilizations very high, to ensure supply the service of our customers, and as a result, we protected our margins. Indeed, the significant progression in our pricing is evident to you on Slide 16. And there, a picture is better than a thousand words. What you can see here is that in Q3, we went from essentially standing -- we were standing still. In the first half, we went up to 7% in Q3 and to an unparalleled, never-done-before 12% in Q4. That's why we've improved our pricing power as the year progressed, and we're really pleased with that. On top of this, we continue to make good progress on our structural cost programs, which you can see in Slide 17. In the fourth quarter, we delivered EUR 40 million of additional savings. That brings the year's total to EUR 213 million, 2-1-3, for the year, and we're giving you a breakdown of that into 3 key areas. Restructuring, these represent reductions in labor costs and that contributed around EUR 75 million. Indirect costs, as we revisit -- really approaching the zero-based philosophy to everything that we do, that delivered EUR 85 million last year. And then we've continued to focus on productivity efficiencies on our industrial sites, which came in with EUR 53 million. And that really is associated with improving our manufacturing yields, which, of course, helps to support the volume growth. Now that brings the total of our structural savings so far to EUR 390 million across the 2-year period, well ahead of the targeted EUR 500 million reduction that we'd indicated by the end of 2024. Slide 18 shows that the positive demand development across many markets, combined with our successful price initiatives and our cost reductions to help us deliver another quarter of strong EBITDA performance, up 24% on the quarter of -- on the fourth quarter of 2020 and up 27% for the full year. Onetime impact of net EUR 27 million in the fourth quarter were also reported in underlying EBITDA, and that includes EUR 61 million of onetime gains resulting from the Brazilian Supreme Court's retroactive decision on duty recoveries for many companies, including Solvay. And we've recorded that gain in the chemicals segment. This gain was partially offset by a EUR 34 million loss, half of which related to bad debt in the energy business, clearly related to an unprecedented spike in energy costs, which were recorded in our Corporate and Business Services segment. I'm going to turn to cash generation on Slide 19. The results of our efforts over the last 2 years to improve our cash generation are evident for all to see. For the 11th quarter in a row, we are generating positive free cash flow with EUR 151 million in Q4 last year and EUR 842 million for the full year 2021. So how did we achieve this strong performance? I'm going to give you the main elements. I'll turn first to working capital. As you'd expect, strong top line growth drove increases in inventories and receivables. The good news is that we doubled down and even drove that discipline even further. And so we -- within that figure, you have structural improvements of around EUR 100 million of benefit and also the benefit of temporarily higher-than-usual payables because of high energy costs. So we continue to manage very carefully our working capital with discipline. Total average working capital to sales in 2021 was 12.7% versus 14.7% in 2020, and mid- to high teens is typically the industry standard. So we're really proud of this performance. Turning to CapEx. We accelerated the investment in the fourth quarter to EUR 324 million, bringing the total for the year to EUR 736 million, in line with our guidance at the very beginning of last year of between EUR 700 million and EUR 750 million. Our ambitions to grow the business are high, and our investment plans are concrete. We are now entering a growth cycle to prepare for the opportunities in the coming years, and Ilham already mentioned a few of these exciting projects. We also spent EUR 118 million, 1-1-8, on our restructuring program, EUR 26 million more than in 2020. And as you know, I consider this an investment because the payback is generally below 2 years. Finally, the deleveraging of our balance sheet has continued unabated, and the continued work on pensions and on debt reduction is paying off. Indeed, pension and financial charges were EUR 89 million lower than in 2020. Compared to 2019, there were EUR 190 million, 1-9-0, below 2019. As a consequence, our free cash flow conversion ratio is over 37% for the last 12 months. Again, it's higher than the ambition we set out of the structural free cash flow conversion ratio exceeding 30%. I do want to make one additional comment there. I'd like to invite you to think of that 30% free cash flow conversion as a minimum average level that we expect to maintain going forward, even though investments in our growth projects may well cause that level to dip in a particular year. We also recommended a dividend increase of EUR 0.10, which, if approved, will bring the dividend to EUR 3.85 per share. Finally, a word on our net debt. Underlying net financial debt decreased again in 2021 by around EUR 250 million to EUR 3.95 billion, mainly due to the higher free cash flow generation, and that's despite an additional voluntary contribution towards pension obligations of EUR 236 million. Since the start of 2019, we decreased our net debt by nearly EUR 1.6 billion. We decreased our pensions by an additional EUR 1.1 billion. Today, the leverage ratio stands at 1.7x, making it the lowest level we've had since 2015, and our credit strength and our strong ratings are really reinforced. And with that, I'll hand you back to Ilham, who'll discuss the full year outlook for 2022.
Ilham Kadri
executiveThank you, Karim. And I'll now share some comments on our outlook for 2022. First, let me share our assumption. First, there will be a negative scope effect in 2022 of EUR 21 million due to the small divestments we made last year. Next, I want to acknowledge that the cost inflationary environment we continue to face is unprecedented in terms of volatility and financial impact. We also are aware of the geopolitical risk and continued uncertainty. In the light of these circumstances, we assume that things will neither improve nor gets worse, and we remain focused on what is in our control. Our quarter 4 results demonstrate that we have the capability to take pricing actions to overcome the inflationary pressures, and going into 2022, this remains a top priority for our organization. We also continue to drive growth across our businesses. Let me highlight some of these assumptions. In the materials segment, we expect growth to be driven by a few key areas: growth in auto, thanks to the shift toward electric vehicles; and continued penetration of our high-performance polymers across all vehicle platforms. We shared with you this story just a few weeks ago during our webinar. LMC forecasts, as you may know -- forecast a recovery in the auto markets, with an approximately 12% increase in global light vehicle production, 2022 versus 2021. The expectation is that the growth will be weighted towards the second half of 2022. This would provide a strong tailwind for our auto-facing polymer businesses where we expect to continue to outperform the general market. Another growth driver is the continued recovery in civil aero that supports growth in composites, with single-aisle production rates increasing this year. We estimate steady improvement in this business. We intend to share more details on this market in the coming months in a similar dedicated webinar to be held in May. In chemicals, Philippe just highlighted the expectations in the soda ash business. This is important because the growth in soda ash this year will help to offset the nonrepeating effects of the super cycle that benefited us in 2021 related to Coatis and RusVinyl, both of which delivered around EUR 100 million more than their cycle average. In solutions, the segment is expected to grow modestly, thanks to the demand for more sustainable solutions in a number of its markets, including agro, home and personal care and others. We are seeing the success of the optimization strategy in this segment, and we see even more opportunities ahead. Given this market view and taking into account our intention to invest more in capability in materials and digitalization and the fact that we expect pricing actions to accelerate this year, we estimate full year EBITDA to grow organically in the mid-single-digit percentage range. On cash generation, we have clearly benefited from the improvements and the discipline in our processes over the past 3 years, and now we will be using some of this cash to fund our growth. I already mentioned a few of these investments earlier related to various high-performance polymers capacity expansions. Altogether, this should bring our CapEx level in 2022 to around EUR 850 million to EUR 900 million, representing a 15% to 20% increase versus 2021, of which half is inflation. Please be aware this doesn't indicate a sustained higher level of spend. Think of it as an investment cycle where some years are higher than others as we prepare for future growth. The expected growth in the top line will likely result in higher working capital needs. This, together with our investment needs in 2022, brings us to a free cash flow estimate of at least EUR 650 million. Of course, this can fluctuate based on the activity levels as we will ensure we meet our customers' needs. As always, we will keep you informed of any changes during the course of the year. I'm sure this year will also have its share of challenges as we continue to emerge from this crisis and some of the secondary challenges it has created. Our team has demonstrated our ability to manage through these near-term headwinds, our solid and improving portfolio, coupled with our strong balance sheet and structural improvements, have enabled us to emerge leaner, stronger and well positioned to progress on our transformation journey and unlock value for our customers, shareholders and our employees. And with that, Karim and, obviously, Philippe as well, our guests today, and myself, we're happy to take your questions.
Jodi Allen
executiveThank you, Ilham. We will now move to the Q&A, and I ask that you kindly limit yourself to one question per analyst so that we can address as many questions as possible today. Moderator, I'll hand the floor back to you.
Operator
operator[Operator Instructions] And we have our first question from Daniel Chung from Redburn.
Daniel Chung
analystCongratulations on the solid quarter. I just got a couple of questions, if that's okay. So first is on -- could you elaborate more on the execution of the pricing actions that have been taken beyond soda ash? And maybe to sort of link that onto a follow-up, so to get to your guidance then of EUR 2.45 billion of EBITDA, is that assuming pricing for the offset costs for the year?
Ilham Kadri
executiveWell, definitely, the pricing has been a new muscle. We just started to train in the company. And me, as -- I mean I'm not a newcomer anymore, but we have our share of crisis since I joined. And when inflation hit us last year and second half looked very different from the first year, we had 2 types of businesses. One type of pool of businesses like soda ash, by the way, and Philippe can elaborate later on, where we had contract pricing either based on a number over a year with no formula or others with formula pricing linked to raw material like in silica with 4 months left, right? And obviously, you want to honor your yearly contracts with your customers. That's why we put the contracts in place, but it was really unprecedented. So price became a real focus of our teams as from mid-2021 when raw materials and energy began to escalate, and we knew this is not something which is going to be lasting for a quarter only. And we have seen a broad-based progress on pricing. We shared best practices with our teams. We said it would take time. You remember, I told you that in quarter 3. But I'm really proud of our teams that in quarter 4, we saw this acceleration with 12% increases in the quarter. Really proud of many. I will give probably the floor to Philippe to talk about what they have done in soda ash because it's the highlight when a team -- a management team and the sales teams are both courageous and brave to go and reopen a contract during any given year and fight for protecting the margins and defend their value proposition, and obviously, what was in a way, almost -- even if it's painful, we could actually renegotiate 2022. But before we -- I do that, obviously, in Specialty Polymers, for example, it was another story because pricing was lagging in the 3 first quarters, right? And we really -- and as you know, in Specialty Polymer, we have a unique value proposition. We went back to the market. We defended our value proposition. And the team succeeded to increase prices, and the acceleration allowed us to compensate the variable cost increase in quarter 4, right? Well, we had a margin squeeze in a quarter 3. So then it depends on each business. Novecare made good progress, but we expect more. And as we enter in January, I can tell you that the pricing in quarter 4 is sticky. We are still looking at pool of pricing leakage where we're not covering our variable costs. We are seeing some escalation on inflation more than what was even budgeted or seen in December. So listen, this is a muscle we are training. We're entering the year with renegotiated contracts, including surcharges. Philippe, would you like to share your experience on reopening your contracts in quarter 4?
Philippe Kehren
executiveYes, absolutely. Thank you, Ilham. Well, in soda ash, most of our contracts, let's say, 90% of our contracts are fixed price negotiated on a yearly basis. The market last year was tight. So obviously, we're able to pass price increases on the open volumes. But again, I mean 90% of our volumes were locked. And we soon realized that it was not sustainable to continue like that because of the unprecedented price increase on the energy markets. I mean we're talking about on gas and coal 4, 5, even more x normal prices. So it was absolutely key to desqueeze a little bit this -- the business already in 2021. And of course, the market being tight, the customers are wanting security of supply and visibility in the long term and also investments that are required for energy transition and for new capacities in the future. We were able, in a lot of cases, not to say in most of the cases, to get the support of our customers. And that's really, really something that was a nice surprise and must -- I must say for -- to mitigate the risk. For 2022, obviously, we renegotiated the prices in a situation where, again, the market is tight and costs are increasing. Here, our target is not only to compensate the costs but really to go beyond that and to get back to the profitability levels that we had pre-COVID in order to be able to continue to invest because we have big investments to be done, both in energy transition and in capacities.
Ilham Kadri
executiveSo thank you. And this is it. I think the pricing muscle was underdeveloped historically. And frankly, this inflation environment, although, again, painful, it's really, for me, a nice opportunity to really engage with the business presidents, the sales organization, the technical staff to really defend our value proposition. You know that Solvay had top-tier margins. So people know that we have great assets. We have great value proposition to offer to the world. And business by business, we are engaging with our customers and really proud of the 12% price increase. By the way, I think maybe some of you think that Coatis has done really -- a great job over the year. But even if you remove Coatis from the price increase, we are at double-digit pricing increase. So it tells you that this is not coming only from the commodity side of the portfolio but also from the specialties. Back to you.
Operator
operatorSo we have another question from Lisa De Neve from Morgan Stanley.
Lisa Hortense De Neve
analystMaybe I slot in 2, if I really may. Can you just share the free cash flow moving parts that underpin your EUR 650 million guidance or minimum guidance for the year? And specifically, I'm looking at what are the sort of provisionals or the net working capital expectations that are baked into that number. And secondly, a small question. So congratulations on your pricing in the quarter. So on materials, you delivered EUR 40 million pricing in 4Q in the backdrop of much higher PVDF pricing and sort of market tightness and higher raw materials. Can you share how much of that EUR 40 million was driven by PVDF pricing?
Ilham Kadri
executiveCan you start, Karim, with the EUR 650 million?
Karim Hajjar
executiveI will start with the EUR 650 million. So maybe a couple of key comments I can help you with. Remember, first of all, that we did indicate and promise to a minimum 30% free cash flow conversion by 2024. We announced that, what, in 2019. We've averaged 44% in the last 2 years. What I want to highlight, though, is I'd like to -- as I said to you when I was giving my opening remarks, take that as a minimum average over time, and it really doesn't preclude that when we have a peak growth investment, that doesn't dip modestly. So don't be surprised if, for example, in '22, it's a little below that 30%. It's important to note that particularly, for example, it's very strategically coherent. We said to you a few weeks ago that we're investing in batteries at a cost of EUR 300 million. Half of that is coming in this year. The other thing I want to highlight is the EUR 736 million we invested this year, if we just take account of inflation, that will move it up towards EUR 800 million. So again, that tells you that in indicating EUR 850 million to EUR 900 million of CapEx, we're making space. We're allocating more to make space and drive that additional growth investment. That's the main one. I think as far as working capital is concerned, 12% is very, very low. Typically, I expect us to want to invest to serve our customers. So working capital investment to support our growth is something you can expect. It really is those 2 key factors that are the main drivers. The other one, which is a little more modest, which is the incidence of our profit pools will impact our effective tax rate by a couple of percent here and there. And I can easily add EUR 20 million, EUR 30 million of extra cash costs. But that's totally dependent on exactly where the -- which geographies those profits are made. Hope that helps, Lisa.
Ilham Kadri
executiveAnd as you know, by now, we'll not let go the free cash flow discipline in this company. So we'll take it as a floor. And obviously, we want to reinvest. And as Karim said, we have great investments, and we -- the markets welcomed our investments in Tavaux. We have a few more in PSU and PCU but also in electronics, in highly purified H2O2 and obviously, in working capital as our customers need to. On your question on materials and price increase, and I gave the example here, on materials before Philippe kicked it in, Lisa, is the highlight of quarter 4, right? And really, the price increase acceleration allowed for the first quarter, frankly, since the past year or 18 months to compensate variable cost increase. And this is across the board. Don't think it's only PVDF. Obviously, we are -- we have record sales in batteries almost under allocation. But the rebound in automotive is across the board, including for other high-performing polymers, which go to under-the-hood application and go to lightweight despite the chip shortage, as you know. Electronic is boosted by the 5G and smart devices, the mobile phones. So all of this is actually booming with Specialty Polymers. And we did a price-over-cost campaigns throughout the year and in quarter 4 with value capture initiatives. We looked at bleeders price initiatives. So where we have price leakages, we are giving much transparency on the pricing and the cost to all our product managers, salespeople to really ensure that there is no -- that they understand the outliers, and we are actually educating our salespeople, such as Specialty Polymers but also expanding to other businesses on large deal negotiations. So there is readiness process, which I've been through when I was a young salesperson, and I think it's good to go back to the basics and multiple deals spanning the GBU portfolio across all large deal renegotiation. And when you are in those inflationary environment, it's good to reopen your contract. We are looking at all our contracts, the payment terms, the pricing leakage, the outliers. We have 40 or 60 deals ongoing now in negotiation. And obviously, we are applying this new format. So yes, you can expect our prices increase to really go across the board, and we shared it in the auto webinar that we were able to pass the cost increase to customers also in auto as the demand is very strong and the supply is still limited. Back to you.
Operator
operatorSo we have another question from Wim Hoste from KBC Securities.
Wim Hoste
analystYes. I would -- yes, like to ask your opinion on the management of the balance sheet. With leverage coming down, how are you looking at things like further reducing the pension deficits, lowering debt service costs? Are there any opportunities just in making your balance sheet more efficient?
Karim Hajjar
executiveThat's a great question. I think this is a journey we've been on. We've really -- as I mentioned, very, very big numbers have contributed to the deleveraging, but what I want to highlight is everything we've done has created value. Just remember that the major reduction in our pension cash service cost in our financing costs is directly associated with that. We're talking of returns, what, in excess of 10% after tax. It's fair to say we're coming to the end of that particularly attractive deleveraging. The next chapter that's opening up is investing with real discipline. I think that's really, really key. So at this stage, what I can say is that our credit strength is improving. Probably, I would speculate -- I would suggest we're probably at the top end of our credit ratings, and we like that. It gives us the ability to maneuver to really invest and do the right thing. But there is no more new major delevering opportunities. We have a bond that comes due of, I think, just around EUR 380 million in September. We've got the cash to pay it. We have to raise new debt. It's a great position to be in. Maybe the only other thing I'll highlight is that with that cash is -- of course, we can look at CapEx. We always look at the right opportunities for M&A. But again, it's not the lack of cash or firepower that gets in the way. It's the fact that we're very, very demanding on the -- on our expectations, on the value creation. So we can look at things, and we're not going to move unless we really find value, which is what we did early last year with the agro business that we bought. Ilham?
Ilham Kadri
executiveYes. No, I fully agree. And frankly, it's good to pause and enjoy the view. The pension, as you know Wim, was the nail in the shoe of Solvay when I started in this company. And I thank the teams and, specifically, the finance team here because the pension funding, there is a lot of negotiation and engagements with the trustees and different institutions across different countries, which happened behind the curtain and the hard work and deleveraging and paying EUR 1.1 billion on pension and on net debt, EUR 1.6 billion, unheard of, frankly, in 2.5 years. So really enjoying to see a strong balance sheet. That's my belief. Any company should have a strong balance sheet. And indeed, we just have a luxury now to contemplate where to invest. We have -- the good news is that since 3 years in the job, we built a really great organic growth platforms, right, which you see. They are real. We can win. We can -- the opportunity is real. We are a winner, and it's worth it economically. So we go for it. And obviously, we continue looking at strategic portfolio but with a high level of discipline. The allocation of resources and the change in governance, which we did since March 2019 has paid dividends, and this is not changing. Back to you.
Operator
operatorWe have another question from Chetan Udeshi from JPMorgan.
Chetan Udeshi
analystI just had a few questions. First one was, I think, in -- within the provision line and also within the exceptional, I think there is a mention of EUR 123 million exceptional costs associated with result from legacy remediation and major litigations, which seems primarily to -- related to remediation costs. I'm just curious to understand where is this EUR 100 million remediation cost, like which part of the business is this related to? Is this essentially going back to the PFAS remediation provisions that you guys are now starting to build up? Any color there will be useful. The -- sorry, a bit technical here, again, is if I look at the cash flow, there is a big bump in the dividend payments from associates and JVs to almost EUR 130 million last year from EUR 25 million in 2020. Do you think this is sustainable going forward? Clearly, I think most of this might be coming from the EVC JV in the last year, but any color there would be useful. And last question, there's a big jump in revenue from noncore activities in fourth quarter. I mean it's more than double versus third quarter 2021. I think this is mainly related to your energy trading and sale business. But can you help us understand if this had any profit impact or EBITDA impact as well given the significant increase in sales?
Ilham Kadri
executiveOkay. Thank you, Chetan. Do you want to take it?
Karim Hajjar
executiveSure. First and foremost, I think I mistold the provision. There's nothing exceptional in the remediation line. Yes, it's a little higher than we've had historically, but there's nothing particular that jumps up in terms of those major outcome and major costs that we flagged. What I want to highlight though is I'm going to confirm what you said because your assumptions are absolutely spot on. The spike in dividends from noncontrolled entities is really around RusVinyl, its dividend, exceptional dividends. Again, we're benefiting from super cycle earnings. And the great news is we're monetizing it. We're crystallizing and getting the cash, record dividends. That's the major part of it. And on the noncore earnings, again, you're spot on. It really is around the equity accounting. It's mainly RusVinyl is the major element here, net of the onetime impacts that we disclosed. Geoffroy, you want to correct me? But go ahead, please.
Geoffroy Raskin
executiveThe revenue from noncore activities relate to energy business.
Karim Hajjar
executiveThe energy business predominantly. Okay. Sorry, I was looking at a different line. Thank you. So that is absolutely the energy business and the onetime impact that we highlighted. Thanks, Chetan.
Ilham Kadri
executiveDoes this answer your question, Chetan? He may be off. Yes.
Operator
operatorSo we have another question from Geoff Haire from UBS.
Geoffery Haire
analystI was just wondering if we could talk a little bit about specialty plastics. And could you talk about the different trends that you may be seeing in volume terms for ICEs and EVs? And also talk a little bit about, do you see a big margin difference in the products that you're selling into ICEs and EVs, please?
Ilham Kadri
executiveYes, of course, and I can take it up. And maybe for those who didn't actually listened or attended the webinar, we held a webinar dedicated to auto, and I think it's now available on our website. Our belief on ICE and move to hybrid and electric is that by 2030, half of the markets will stay with ICE, internal combustion engine car, and the other half will move to hybrid and BEV. Obviously, there is an ICE power train in the hybrid, so that's good for us, and along with the electric powertrain. We also shared with you that the opportunity is real for us. We've seen it. It was stress-tested during the COVID-19 because our, frankly, electric PVDF and other polymers to lighten the car has been just increasing, including -- in the midst of the crisis. And our numbers we shared with you that we grew this business with an -- with a CAGR of 8% between '16 and 2021 from EUR 500 million to EUR 800 million altogether and that this number will likely become EUR 1.5 billion by 2025 and can go above and beyond EUR 2.5 billion by 2030. And that's a great opportunity. I mean you see that investing in PVDF and upstream monomers and feedstock is a high barrier to entry. In fact, I was in Tavaux just a few days ago to start and inaugurate, I mean, this new construction. And actually, we're building 5 different plants, all vertically integrated. We also -- what we told you in terms of the opportunities that we double our addressable markets and value by market, which is great for the company and the revenues. And we are in suspension just to finish with the technology, and suspension, as compared to emulsion, it's the supply of choice for high-end batteries. I mean, basically, it gives a better electric addition in NMC, for example, as compared to the emulsion technology. So all in all, we feel really good about that. The margins are as good as we have today. So we will keep our margins. We will double the accessible market. And we have the technology, the know-how, the customer access, the conversation, right? Our customers were really involved with us in making these investments happen in Europe in localizing the value chain for batteries. And at the end of the day, we're also agnostic to the cathode type. We are agnostic to the industry in a way because PVDF goes to other businesses. So there is a derisking here of the investments. Obviously, you know that in Changshu in China, we also doubled our capacity, and we are now looking and discussing how to invest further either in Asia or in the United States of America. Back to you.
Geoffery Haire
analystCould you possibly comment on just what you're seeing currently in Q4 and what you expect to see in the first half of 2022 in terms of EVs and ICE demand?
Ilham Kadri
executiveYes. Yes. So great question. And we've seen a very strong demand last year. Remember, 2020, when we get out of it, obviously, there was a lot of destocking during the crisis, et cetera, and you had to rebuild in 2021. And in quarter 4, frankly, there was a lack of seasonality in quarter 4 with strong demand, especially in batteries, right? So we've seen this very strong, the order book entering to quarter 1, remains -- I mean our order book covers anywhere between 8 weeks to 10 weeks, right, for Specialty Polymers. So demand indicators continue to align strongly with the order book, and pricing remains the leading indicators, right, on there. So we shall see on the raw material and the inflation, how we're going to engage into quarter 2. You've seen LMC numbers. I shared them with you. It looks like they are very still comfortable although it can change later but confident that 2022 will deliver double-digit growth, probably heavily weighted towards the second half than the first half. But for us, the order books are still strong, and that's what we see today in our books. Back to you.
Geoffery Haire
analystAnd is that order books in both ICE and EVs are still strong?
Ilham Kadri
executiveYes. I mean higher -- I mean there is a strong demand in electric batteries, right, and demand for products for EV and hybrids, but definitely, the ICE is still okay, yes. And don't forget as well, I'm just -- beyond what you see from the ICE build rate against electric hybrid is that we are also in lightweight. So we enter the existing models and the existing technology whenever we can replace metal and we can lighten the vehicle, which goes, as you know, into cutting the emissions and allowing the car manufacturers to become more sustainable. You heard it from -- again, celebrate that Philippe is with us that EV is emerging, is small, is new but will be also benefiting the mining and the soda ash businesses. Back to you.
Operator
operatorSo we have another question from Mubasher Chaudhry from Citi.
Mubasher Chaudhry
analystJust one, please. You've had relatively good performance and cash generation as well as you talked about deleveraging and having a good balance sheet and starting to focus on organic investment. Is it fair to say, from a capital allocation perspective, that the focus is very much on organic delivery and focusing on the business as it currently stands, therefore, M&A is off the table? And if not, is there any preference for size or -- and market exposure that you'd be most excited by from an M&A perspective?
Ilham Kadri
executiveThank you, Mubasher. Well, listen, I think you're right. Since I joined the company, frankly, my first objective was to deleverage the balance sheet, to make the cash generation not a fourth quarter story but a quarterly story with high discipline. And you remember, we've changed our incentives, and frankly, this organization had just responded better than good. So we really trained the muscle. So very happy with the generation of the cash across all the businesses. I think, again, Philippe is here. And soda ash, it has been and is a resilient cash generator, but other businesses, Specialty Polymers and hydrogen peroxide, et cetera, they are equally generating quality free cash flow, and the conversion has been really good. Now in terms of investments, since I joined the company, I was really looking at what are those key big bets we have in terms of organic growth. And we do have quite the substantial great projects, and you've seen them. I mean batteries is one. We're investing in thermoplastic composites. We just finished our investments in Greenville in the United States of America. Green hydrogen is still small, but we are putting a semi-commercial plant for Aquivion membrane for green hydrogen. We announced earlier this week the PSU, the Udel story for health care, high-margin businesses. And then ultra-purified H202 peroxide, which goes to semiconductors, and the world is short and thirsty for getting more semiconductors, and our customers are asking us to invest very close to them. So after our joint venture, an alliance in Taiwan, we are looking at investments here in Europe. We don't have yet the final choice of the manufacturing plants, but we will inform you. On the inorganic side, first of all, there is no sacred cow. We look at it from the strategic planning point of view. We are disciplined. And if there is a strategic fit, and we believe we can be the best owner. The next question for me will be how much it will cost, is it creating value. And I know our history has been debated a bit on past acquisitions. So we want to -- we will look at it, and we do it right, including the synergies. What are they? What are the expected returns? So no emotion. It's very clinical, based on facts, and we will extremely discipline on any inorganic M&A.
Mubasher Chaudhry
analystGreat. Just to come back to you on that. Is there any limitation on size and anything? Kind of would you be keen to go for bolt-on side? Or that doesn't matter regardless if it -- if much is the investment criteria and is attractive, you're open to bigger ticket M&A as well?
Ilham Kadri
executiveSo I don't want here to change the risk profile of the company, right? So I'm very careful with the big acquisition we have. Remember, I mean, we exited 50 -- cycle of 50 M&As. After the acquisition of Rhodia and Cytec, we had actually to merge those, integrate them, build the synergies, which happened very recently. We contemplated, and we still do small M&As to buy and build in agro. You remember, we did a small one last year, so that's good. But big is not necessarily beautiful or profitable. So I'm very -- I've seen many bigs in my career. So I'm very prudent, and I will continue to look, obviously, at all the options on the table but with discipline in returns. Back to you.
Operator
operatorSo we are going to take a last question, Andreas Heine from Stifel.
Andreas Heine
analystIt's on soda ash actually. I would like to come back to the comments you made on what soda ash can deliver this year in the context of the overearning of Coatis and RusVinyl. And you cited that the last 2 were overearning by EUR 100 million last year and might not do this, this year. Is that right that you are so optimistic that soda ash might increase earnings by EUR 200 million this year on the tight market and the price increases you have achieved at the beginning of the year? That's the first question. The second related to this is soda ash as variable costs are highly dependent on the energy cost. And my understanding is in looking at your annual report, you have quite high hedges in energy. How is it for 2022 in the current market? You have now the annual price, and you know where energy prices are currently on the spot market. How you handle hedging your energy position? Or will it be a more open position this year?
Ilham Kadri
executiveYes. I will give the energy question -- I will leave it to Philippe as he is with us. But definitely, on the EUR 100 million, we're not saying -- I mean there is a super cycle. You understood it from Coatis and RusVinyl, which we evaluated around EUR 100 million. This is baked in our guidance of mid-single digits for the EBITDA for 2022. We don't give guidance by GBU and by business, right? But obviously, we'll give you more color as I expose some of my GBU presidents over the year to give you the quality of the business. And I think what Philippe is saying is that after 2020, where we elected to let go some low profitable volumes in the market, we did it really intentionally, right? And frankly, it worked very well for us in 2021. We actually -- really, we were more resilient and more profitable than our competitors, right, because we have discipline, we protect our margins, and we renegotiated our prices. And I thank, again, Philippe and his team to be bold and courageous to reopen, historically, some of the contracts and not only to see the impacts in quarter 4 but definitely in 2022, including having energy surcharge. Philippe, can you build on that?
Philippe Kehren
executiveYes, absolutely. Thanks a lot, Andreas, for the question. Indeed, I mean we are extremely exposed to energy markets. As you know, it's the biggest part of our variable costs. Well, the answer is very simple. It's a combination of hedge that we've taken. And also, under the current circumstances, some new contractual clauses that allow us, in some cases, either to pass on those extra energy costs, in particular, if they continue to go up, and we feel this might happen given the context. And also some reopeners that would allow us to pass some price increases. So this is exactly what we are doing. What I would like to mention on top of that is that it's highlighting the fact that doing the energy transition is key because moving from coal or gas to refuse-derived fuel, biomass and so on with local sourcing, local sourcing that we can secure on the long term, help us to get out of this huge volatility that we see increasing month after month on the fossil fuel energy markets. Thank you.
Ilham Kadri
executiveSo thank you. And to clarify, it's EUR 100 million. It's not EUR 200 million. So I don't want you to walk away with that number. So yes, just to be clear. Well, listen, I think it's the last question, and I would like really to thank Philippe. He's the first one now joining us in an earnings call, and you will see us having guests from different businesses as we continue building the equity stories of our strong and robust portfolio. Thank you. Thank you very much.
Jodi Allen
executiveThank you, everyone. This concludes our call today. And as always, the IR team is available for any follow-up questions that you may have. Thank you so much, and have a good day.
