Thank you, Christoph, and good morning. Medmix was born in September last year with the decision of Sulzer's extraordinary AGM on September 13. On September 30, our shares were listed on the SIX Swiss Exchange and also traded the first time. In parallel, we have raised successfully CHF 295 million that we will use to invest in organic and inorganic growth. Everything went smoothly, and our operations have not been impacted by the spin-off. While most of our markets recovered relatively quickly from the lows in 2020, the pandemic itself, with continued lockdowns and restrictions, as well as knock-on effects and supply chains, remained a challenge. Still, we have delivered fully on our guidance as announced to the Capital Markets Day in June last year, and we have made major steps towards our midterm targets, particularly in drug delivery.
Our revenues increased by 30% to CHF 457 million. Our adjusted EBITDA margin was up 6.2 percentage points to reach 25%, and free cash flow came in at CHF 56 million, which is CHF 46 million higher than last year. Part of that will benefit our shareholders, as our board proposes a dividend of 50 Rappen per share to the AGM. As mentioned before, we delivered revenue of CHF 457 million, 30% above the previous year, 21% on organic basis. We are back to 2019 pre-pandemic levels on an organic FX-adjusted basis. Healthcare business area revenue grew 64% over the previous year, 34% organically, and represented 37% of our revenue. Consumer and industrial business area grew 16%.
Dental segment grew strongly thanks to the pent-up demand across the value chain as the dental practice occupancy gradually recovered. Our revenue in Dental segment grew 42% to CHF 116 million, and thus is around pre-pandemic levels of 2019. Not all end user markets have fully recovered yet. We grew through expanded product portfolio and through improved market coverage as we deployed resources to the U.S., Brazil, India and China to work with local trade. We are very pleased with the traction of the market coverage initiative. 2021 was the first fully integrated year for drug delivery. In the course of the year, we strengthened our commercial and R&D teams, made good progress on the auto-injector development, as well as secured new customers for our D-Flex injector pen platform, including U.S. biotech companies.
With this, our drug delivery segment has successfully started a transformation from a predominantly European player to a global business. Our organic growth in 2021 was 38%. Surgery segment delivered CHF 13 million. The strategic focus on the tissue banks in the U.S. proved to be successful, with strong growth in the first year of this initiative and partly compensated for a non-repeat project we had in 2020. Industry segment experienced a very early and healthy market rebound across key industries like construction and electronics. 2021 was a record year for industry, delivering CHF 161 million. The 28% growth from prior year was a combination of pent-up demand, market share gains, temporary growth spikes in some markets, and higher underlying market growth as chemical fastening applications gained popularity.
Beauty segment experienced slower post-COVID recovery than our other segments as the global demand for liquid color cosmetics remained dampened due to continued lockdowns, home office work, and low travel activity. Nevertheless, the Beauty segment grew 4% to CHF 127 million. In the last few months of 2021, we saw encouraging signs of accelerated market recovery also in Beauty. We expect that the Beauty segment will recover to pre-pandemic levels by the end of 2022. Overall, we're happy with the performance of all our segments. In the next few slides, let me talk more about the Healthcare business area. Revenue for the Healthcare business area grew 64% adjusted for FX over the previous year, 34% organically, with markets rebounding significantly from lockdowns and the closure of dental offices that we experienced in 2020.
The healthcare gross profit margin was 3 percentage points lower at 61%. This is mainly due to the consolidation of our drug delivery business for the full- year versus only one quarter a year earlier. In addition, Haselmeier had more development and customization projects in 2021. Such projects carry a lower margin initially but guarantee future sales. We have said that we have won one larger project in the first half, and we have won additional three in the second half. Things are really on track here. Without these effects from drug delivery, our gross profit margin in healthcare stayed essentially flat. On the next two slides, we show you some products we launched and awards we have won in healthcare. MIXPAC T-Mixer for Dentistry, launched January 2021, was awarded Dental Advisor's coveted Top Product and Outstanding Quality award in 2021.
Since 1983, Dental Advisor has been a trusted expert to dental professionals worldwide. The mission of Dental Advisor is to provide the dental profession with evidence-based and clinically relevant information on dental restorative products, infection control products, and dental equipment. The T-Mixer is offering same or better mixing performance as previous generation mixers while being 30%-40% shorter, thus reducing extensive waste of dental material. This award yet again affirms our position as the innovation and quality leader for precision delivery devices in dentistry. Colibri Plus Breakable was also launched in January. It is an all-in-one solution for multiple dental materials and specialty applications, one mixing tip for several applications like impressions, root canal, and cavity preparations, has integrated smoothly rounded stainless steel cannula for easy access to difficult areas and minimized risk of soft tissue trauma.
Colibri Plus Breakable allows us to expand to care areas outside of prosthetics and restorative and provides solutions for an unmet need in dentistry. In surgery segment, we launched medmix ErgoSyringe, a ready-to-use biomaterial system for storing, hydrating, and delivering biomaterials. ErgoSyringe is an amazing productivity enhancement for the surgeon. It eliminates the need for manual mixing in the operating room and enables single-handed operation for physicians. We have also delivered on significant milestones in drug delivery, the segment with the strongest growth outlook in the coming years, as seen on page 9. The D-Flex ecosystem automatically collects and manages self-injection data directly at patients' homes. Using integrated optical sensors, this connected solution provides valuable feedback, not only confirming that the patient has taken the medication, but also indicating the precise amount administered each time. Connectivity via smartphone app means patients receive a reminder if they forget to take a dose.
It allows pharma companies to truly understand real patient behavior and its impact in new therapies. Wearables may be integrated to complement the clinical picture of patients, which is particularly beneficial during new drug development and clinical testing. Early 2021, the D-Flex ecosystem was announced the winner of the prestigious Good Design Award for 2020. We were laying the foundation for future growth in drug delivery, also in innovation. In the course of 2021 alone, we filed for more than 15 patents, not only for the upcoming auto-injector addition to device portfolio, but also for D-Flex platform and connected caps. Our first prefilled syringe auto-injector will be launched in the course of 2022. Available in 1- and 2.5-milliliter versions, it will be, like D-Flex, compatible with the connectivity ecosystem. Our D-Flex platform continues to resonate with pharma and biotech companies worldwide.
As of the end of 2021, we have development agreements with 6 customers for D-Flex platform. Moreover, we have expanded our offering to include pharma licensed services such as final assembly and packaging, and have already won several projects. Therefore, we're confident about our growth outlook in drug delivery. Moving on to consumer and industrial on slide 10. In this business area, our revenues went up by 16% FX adjusted and organic. On the industry side, we benefited from a recovery in electronics, construction, and automotive markets. In the latter, mainly thanks to electric vehicles. Beauty grew also but at a slower pace, as there have still been pandemic-related impacts in retail and travel. While we do the bulk of our beauty business still with the traditional beauty companies, 20% of our revenues stem from independents or indies, as we call them.
Our new offering based on the extended and revamped factory in Bischofszell starts to pay off. Thanks to a better mix as well as improved margins in Beauty, our business area gross profit margin was up 1.9 percentage points to 41%. Also, in Consumer Industrial, we have some exciting new products to show. 2 of GEKA's product innovations won IT Products Awards at MakeUp in Shanghai industry event in 2021. In our core category, mascara brushes, we won innovation awards for the Pure Definition mascara brush. It is a new design brush created using our bi-injection sandwich technology. Many molded mascara applicators are made from only one plastic, meaning the bristles are hard and too harsh for sensitive eyes. Our sandwich technology combats this issue.
A bi-injection process manufactures the brush from two different plastics, allowing the applicator to have both a hard core and soft bristles. For a launch in our Beyond Mascara strategic initiative, fusionAPPLICATOR was selected a winner among 38 novelties in a packaging innovation category. It is an innovative applicator with very delicate micro bristles for precise, pure, hygienic, and smooth application of formulation. With overall 50 bristles with more than 4 bristles per sq mm, fusionAPPLICATOR is ideal for skincare treatment like vitamin C application to ensure dosage application with maximum precision. The nano twisted wire brush, also launched last year, is a fiber brush with a wire diameter of less than 0.5 mm and a trim diameter of less than 4 mm.
It is ideally suited for professional brow treatment as well as for mascara, for example, Asian market, matching the local needs of Asian lash characteristics. Last year was also a busy year for innovation and industry segment, as seen on slide 12. We are supporting our customers in reducing their CO₂ footprint through the entire value chain by following eco design principles in our product development process. Eco design principles guide our design teams, optimizing new products by reducing size, weight, and number, and type of materials. We prove the impact of our design improvements with life cycle analysis for new products. As an example, EcoPack is one of such products. It has been proven to reduce CO₂ footprint by more than 75% compared to solid cartridges due to significant reduction of weight and volume during transportation and storage, as well as waste volume.
Massive, massive CO₂ reduction compared to standard cartridge. We secured several new customers for this award-winning product last year, including Chinese customers active in a tile grout segment, one of the untapped markets we had planned to address. Blueline system, launched in 2021, is an enhanced dispensing system, specifically addressing high-viscosity and compression-sensitive materials. Blueline allows for much faster application, up to three times the desired amount of adhesives in a wide range of construction and industrial uses. In combination with T-Mixer, it contributes to significant waste reduction. Thus, eco-design principles are at the core of our product development for industry segments. Now, let's talk about sustainability on slides 14 and 15. Our approach is based on three pillars, planet, people, and profit. For planet, we have taken actions to reduce our emissions and switch our sites to low carbon electricity.
8 out of our 13 sites now operate on low carbon electricity. We also aim to reduce water consumption of our own operations and minimize waste to landfill. We have made progress on both targets. For people, we conducted an employee survey last year. 89% of our employees participated. Out of these, 83% responded that they are sustainably engaged. This is a higher score than for other comparable companies. We undertook 18 community engagement initiatives ranging from clothing and food donations to special equipment for certain groups of people. On profit, we successfully introduced eco design principles into our product life cycle. We completed EcoVadis assessment for 5 out of 13 sites and achieved platinum status for Bischofszell for the second year in a row. It was also the first site to receive this status in the industry.
A platinum rating reflects a sustainability score among the top 1% of companies worldwide. We achieved gold status for Elgin and silver status for Hungerford. On slide 15, some additional examples of how sustainability drives our product portfolio across the company. Beauty segment is the forerunner in this field. Cosmetic companies were among the first ones to incorporate sustainable and recycled materials in their products. PCR, meaning post-consumer recycled materials, are already actively used in Beauty. On the left-hand side of the slide, you can see the new liquid concealer system with a crystal clear PCR container. Most of Beauty product range can now be made of sustainable materials. Leveraging material know-how best practices from Beauty, we have finished development of greenLine cartridge for industry. Our first 100% PCR polypropylene cartridge that retains full functionality of the standard cartridge and with significantly reduced carbon footprint.
in drug delivery, we started to use bio-based plastics instead of oil-based materials, which reduces CO₂ footprint by 84% per kilo. We take multiple actions to reduce our CO₂ footprint and also that of our customers. Let's turn to operations on slides 16 and 17. 2021 was the second year of the pandemic, and we experienced significant headwinds with respect to material availability and pricing. We also had to cope with a steep increase in logistic costs and with supply chain turbulences. In addition, COVID waves have also affected our workforce in the factories quite a bit. despite all this, we ensure the availability of raw materials and transportation without supply disruptions. Here I must highlight the incredible work of our global procurement team has done. Here, our setup with different end markets with mutualized operations made a clear difference to competitors.
We maintained our production throughout 2021. All factories remained open at all times, even with reduced workforce availability due to COVID. We completed the integration of our drug delivery business. The best is that you will find no trace of the headwinds and hassles in our financial performance. Revenues were up 30% and our adjusted EBITDA margin was at 25%. In addition, we moved forward with some significant footprint projects that will support our future growth. We have completed the site expansion project in Bischofszell, Germany and introduced advanced manufacturing, automation, and quality technologies. We increased our capabilities by insourcing decoration. We doubled the capacity of our production facility in Wrocław, Poland, which mainly caters to our industry segment.
We also doubled the capacity at our logistics hub in the U.S., which will reduce the lead times and increase service levels for customers of our industry and dental segments in the U.S. We will expand further in 2022. For example, we have signed a lease contract for a new production facility for our healthcare business area in the U.S. We have already started to work on the fit-out. Now, over to Jennifer for the financial review.
Thank you, Girts. Good morning and welcome also from my side. Girts has already mentioned some of our figures, and I'll comment a little more starting on slide 19. Firstly, the most important thing for me to say is that we did what we said we would do. We delivered strong financial results in this year of our spin-off from Sulzer and delivered on our guidance for 2021. That's definitely enough to make this new CFO smile. Our revenue was up 30%, adjusted for FX, 22% organically, and is back to 2019 pre-pandemic levels. Our business area gross profit margin increased by two percentage points as healthcare is growing faster than the industrial and consumer business.
Our gross profit margin increased 5.1 percentage points, driven by the improved mix just mentioned and as well our higher volumes increasing utilization rates in our factories. The difference between our business area gross profit margin and the gross profit margin reflects that our manufacturing footprint is mutualized to a large extent. Transverse costs, global teams, and impacts of utilization are therefore reflected below business area gross profit. Adjusted EBITDA margin increased 6.2 percentage points and was in line with our guidance. I'll give you some more insight here on the next slide. The impressive improvement in net income is due to the higher adjusted EBITDA, as lines below have not really changed that much, maybe with the exception of tax, which is again on a normal level.
Finally, free cash flow has also multiplied from the previous year's level, driven by higher profits on higher volumes. Now let's move to slide 20 and our adjusted EBITDA bridge. Our adjusted EBITDA margin is approaching pre-pandemic levels, though we are not there yet. Most of the uplift came from higher volumes, as you can see. Price and mix also had a significant impact, mix more than price, with healthcare moving from 30%-37% of medmix revenue. The other bar here shows the impact of several items. The positive impact of the additional 3 quarters in 2021 of Haselmeier, and the negative impact from the partial reversal of the OpEx squeeze we pushed in 2020 during the first part of the pandemic, where we lowered our discretionary costs such as travel and entertainment, marketing events, and found creative ways to work with our customers for consulting, etc.
On slide 21, you see the bridge from adjusted EBITDA to net income. There's not too much to comment on here, I'm happy to say. Just briefly, non-operational costs are predominantly one-off costs related to the spin-off from Sulzer and the set up as a standalone company as flagged during the CMD. Income tax was again at a relatively normal level of CHF 7 million, resulting in an effective tax rate of 14.3%. Moving on to slide 22 and free cash flow. Our net working capital increased in 2021 due to higher volumes and the rebuild of inventory to gradually transition back to our make to stock model and secure the lead times and remain agile after the turbulence of 2021.
Capital expenditure remains a little ahead of depreciation, as is normal in a growth business like ours, but at 7% of revenue was a little lower than planned. We said we'd be closer to 9% revenue. The shortfall was mainly the result of some projects not moving as fast as planned, held back by various pandemic related impacts, including machine lead times. We plan to spend a little more in 2022, around 9% of revenue, and our key focus will be on the ramp-up of our U.S. healthcare footprint. With free cash flow of CHF 56 million, we converted 126% of our net income to free cash flow. The last slide for me, slide 23, but an important one.
With our strong balance sheet post-spin-off, we are able to support our growth ambition through organic scale up and efficiency projects, as well as targeted M&A opportunities. The proceeds from the capital increase we use to strengthen our equity base as well as to repay a part of our debt. Our loans with Sulzer were repaid and we refinanced with banks. At the end of 2021, our net debt to EBITDA ratio stood at 1x. With this, I hand back to Girts for the outlook.
Thanks, Jenny. Now let's move to slide 25. For 2022, we target organic revenue growth of 8%-10%. We expect more normalized volume development as compared to last year, and we also expect to recover to pre-pandemic levels in all segments by the end of 2022. The targeted growth also means that we are growing 1-2 percentage points above our markets, gaining share. We started very well in January, and February is also very promising month to date. We expect our adjusted EBITDA margin to go up by 1 percentage point to 26%, mainly driven by continuing shifts in mix and obviously also by again, higher volumes. Still, we will have to cope with continuing pressure on costs and supply chain, and we are also investing in projects for our future growth. Our midterm ambition remains unchanged.
We target a revenue CAGR of 8% and an adjusted EBITDA margin of 30%. Let's summarize on slide 26. 2021 was an excellent year for medmix. I am very proud of what we have achieved. The spin-off was successful and we have not seen any adverse commercial or operational impact because of it. We see good traction on our growth strategy with projects gaining momentum with customers and innovative products launched. We reached the targets that we had set for 2021, and we will do our best to do the same in 2022. The strong free cash flow and balance sheet will support our organic growth and allows for targeted M&A. It also allows to propose a dividend of CHF 0.50 per share to the AGM. On these words, we're at the end of the presentation and will now take your questions.
