Good morning, everybody, and thank you very much for joining us today. Joining me on this call are Carol Kane, Executive Director, and Neil Catto, CFO. Today is an extended results presentation to allow the time to go into some more detail around the changes we are making around sustainability and in response to the independent review. I'm also delighted to be presenting a very strong set of results for the six-month period to the end of August. A lot has happened over the last six months. We're a much bigger business and a significantly strengthened business compared to where we were at the start of the financial year. It's obviously been a challenging period of intense scrutiny. I want to be balanced today. I'd firstly like, again, to thank our team, who have worked hard to help the group deliver the half year result.
I also recognize that there is a lot the group still needs to do to improve its corporate governance, compliance, and monitoring processes. In terms of the running order, I'm gonna start by providing an update on our sustainability strategy. Neil will then talk through the economics of our supply chain before moving into the half year results. Carol will finish by providing an update on the group, our nine brands, and the progress we've made with our most recent acquisitions. I will provide a summary, and we will then move on to Q&A. So starting with a recap of Friday's announcement. On the eighth of July, the Boohoo Group Board announced it was undertaking an independent review of its UK supply chain, to be led by Alison Levitt QC. The findings of the review were delivered to the board on twenty-fourth of September.
On 25th of September, we published a review in full to demonstrate our commitment to increase transparency and communication around sustainability matters and our supply chain. It's a long and detailed document, which hopefully you've had a chance to go through in full by now. In short, the review identified many failings in the Leicester supply chain. While steps for improvement were in progress, the board and I recognized that we should have acted faster to remedy problems in Leicester. As I said on Friday, Boohoo has a huge influence on the UK textile industry. Our ongoing commitment, both to UK manufacturing but also to working in conjunction with local partners to improve standards in the region, means that we have the ability to be a real driving force behind positive change.
Today, I'm gonna provide further color on all of the steps we are taking to ensure that these issues will not recur and to rebuild confidence in the board's oversight of such matters. Today, I want to demonstrate how sustainability is key to our strategic and financial ambitions. The independent review has identified supply chain issues which are significant and unacceptable. The impact of the review has been to highlight to the board areas where the group needs to strengthen its governance and oversight and its supply chain compliance processes. Put simply, we are aware that we will not achieve our ambition to be the fashion e-commerce leader, not be a strong investment proposition, and not succeed if we do not get this right in terms of compliance and sustainability. In response to recent events, the group has accelerated its planned investments.
These will significantly enhance its internal audit and compliance procedures and the board's oversight of these matters. The critical output from this is that we intend to rebuild all shareholders' confidence that these matters will be dealt with appropriately and sensitively and that they will not recur. The upside of this investment is the growing and positive contribution we will continue to make into the UK textile industry and economy as a whole. As I said on Friday, we will get this right, and all our stakeholders will benefit. Our customers can take reassurance that our suppliers are being treated fairly, our colleagues will feel greater pride in working for the group, our shareholders will have greater confidence in the board's oversight, and our investment will benefit the Leicester region and the UK manufacturing industry and its workers as a whole.
Before we get into the detail around our supply chain, I wanted to touch on our culture at the Boohoo Group, particularly in light of some of the more recent press. The board will ensure that all of the points raised by Ms. Levitt around our corporate culture are investigated sensitively and with due care. However, I'd like to give my personal view today. I've now been CEO for 18 months, and something which really stands out alongside our great people is our culture, energy, and drive to be the leader in our sector. We hold ourselves and our staff to the highest standards. As a group, we're ambitious and keen to drive positive change.
We're collaborative, perhaps best demonstrated through our ongoing commitment to U.K. manufacturing and the support we've shown to our suppliers during the COVID-19 pandemic, and before with fourteen-day supplier payment terms that we introduced last year. Our founders are both actively involved in the business, and that entrepreneurial culture extends throughout the business. We're not afraid to make bold decisions and act quickly, as shown by our fast response to recent events. Our culture is and always has been inclusive, and this is reflected in our brands and our products.... We have one of the broadest fashion ranges on the market, covering size 4 to size 24 and over 70,000 styles. And lastly, I wanted to emphasize on behalf of the whole board, how committed we are to rebuilding the trust in us and the business to act in a responsible manner.
I'd also like to touch on the Group's broader contribution to the U.K., which extends far beyond our financial success since our IPO. We've grown significantly with sales of nearly GBP 1.5 billion, and Adjusted EBITDA of over GBP 150 million over the last 12 months, up from just GBP 110 million sales and GBP 12 million Adjusted EBITDA at our IPO just 6 years ago. What incredible growth! But the positive impact of this success is far greater. We've created over 5,000 jobs within our operations across the Group, including our 3PL warehouse in Sheffield, and far more indirectly, if we consider our broader distribution network and supply chain. We've resurrected some famous British heritage brands, saving and creating over 200 jobs that would otherwise have been lost as they went into administration.
Half of those colleagues are current shareholders in the Group, meaning they are sharing in our success as a public company, and in total, almost GBP 40 million of wealth has been realized for those employee shareholders since we floated. We've consistently contributed in terms of tax. For example, we have a corporation tax rate that's above the headline rate. Since IPO, we've contributed more than GBP 80 million in the form of corporation tax. Our supplier base has naturally evolved as the Group has grown, and we have an increasingly international sourcing mix. This is both in response to the growth in our product ranges as certain products like shoes, jeans, and jackets are not manufactured in the UK. But also in response to our growing number of brands, with our new brands like Karen Millen and Coast, producing more detailed and tailored products.
The types of products manufactured in the U.K. tend to be more basic products with very simple cuts and trims. Reflecting the shift in our product mix and brands, approximately 40% of our products are manufactured in the U.K. today, down from over 70% at the IPO in 2014. We're increasingly sourcing in Asia as well as Europe, which is key, which is a key market, particularly for our newer, higher price point brands. Over the next few slides, we've mapped out what the Group is doing to audit its U.K. and international supply base and get comfort over its existing supplier base. We've set out processes we're putting into place to ensure that the issues identified over the last few months will not recur and provided an anticipated timeframe over which we will work through these processes.
Starting with Phase One, where I'll cover off the planned audit and compliance enhancements, which were already in progress from the start of 2020 before we commissioned the independent review. Phase Two covers the accelerated audit processes in response to the independent review, as well as that review's findings. Phase Three sets out a roadmap for how we plan to address the initial findings and report's recommendations. And Phase Four will cover how we will roll out these processes internationally. Supporting this roadmap is a significantly strengthened team. Since I started working with the Boohoo Group, part of my focus has been building out our team in the areas of sustainability and compliance, and we've made some fantastic experienced hires. I've created two key new roles, which are the director of sustainability and the director of responsible sourcing.
Supporting these directors are multiple new hires with experience covering compliance, audit, sustainability, and stakeholder management. Starting with phase one, we were due to launch a full UK compliance program review at the start of 2020. This was signed off with our compliance specialist partner, Verisio, in February, with a view to commencing with a supplier conference in Leicester at the end of March 2020. This was to educate suppliers around our compliance processes and what the review would entail covering. The Boohoo Group Code of Conduct, which sets out the relevant requirements of being a supplier to Boohoo, and the Group Supplier Guidance tool, which sets out clearly what suppliers must do to ensure that they comply with the code of conduct.
The object of this program is to carry out a deep dive into the Group's supply chain, including a full mapping exercise of all UK suppliers and their manufacturing subcontractors. This was intended to improve our supply chain visibility and ensure compliance with our enhanced standards across the UK manufacturing base. We chose to work with Veriso as a partner for this program, as all Veriso auditors are full-time social compliance auditors. Veriso committed to a forensic review of wage payments, and they planned unannounced visits, and we felt Veriso would provide a higher benchmark for standards from our suppliers with uniformity of standards across the supply base. The launch of this program was postponed due to the outbreak of COVID-19, and we subsequently launched the program on the 29th of May. Moving now into Phase Two.
Following the allegations raised earlier this summer, the Group took the decision to accelerate the audit work that Verisio was doing. On the eighth of July, we announced the independent review of our UK supply chain, led by Alison Levitt QC. We made an initial commitment to invest an incremental GBP 10 million to eradicate supply chain malpractice. We accelerated our independent third-party supply chain review with ethical audit and compliance specialist Verisio, and we brought in another international specialist, Bureau Veritas, on board to assist with this. We took the decision to focus the immediate audit work on the core areas addressed in the allegations. These included COVID-19 risk assessment, right to work, working hours and wages, furlough validation, contracts, health and safety. Verisio allocated a further 6 auditors for initial period of the 3 weeks to enable us to quickly review a higher volume of suppliers.
The initial work conducted by Verisio has identified around 150 suppliers and around 400 subcontractors to date. Over half the suppliers and subcontractors have been visited by Verisio. Miss Levitt's review identified issues at a higher proportion of the sample of suppliers her team reviewed. This is consistent with the findings of Verisio. Our supply chain compliance department is considering each supplier on a case-by-case basis. To date, the group has terminated relationships with a handful of suppliers for material breaches of its code of conduct. However, our approach will be to work collaboratively with suppliers on a case-by-case basis to remedy issues as a first step, rather than terminating relationships. Our phase three focuses on our response to our own review, as well as Miss Levitt's report, which was published last week.
As we said on Friday, we plan to implement Miss Levitt's recommendations in full, and these are set out in detail in the appendix of this presentation. To recap, the most significant actions we are taking are plans to strengthen our purchasing and buying practices, including strengthening the sourcing team through further experienced hires and implementing a new set of purchasing principles. We will also increase the level of transparency of our supply chain through consolidation of our approved supplier list. A smaller number of larger, more efficient, and well-managed suppliers should result in increased productivity, better quality control, compliance, and reduced wastage.
Completing our audit process across Tier One and Tier Two suppliers in the U.K., after which we will publish a list of our suppliers within the next 6 months and update on this annually, and extending our independent audit program across the rest of our U.K. and global supply chain. The last phase, phase 4, is about rolling out our compliance program internationally, first to China and our Asian sourcing markets, and then to our main market, international, for example, Turkey and Italy in Europe. We will be working with a third party, Bureau Veritas, on this, who are recognized internationally as a leader in sustainability and compliance. We plan to publish our international supply base within the next 12 months when this work is complete.
Turning now to our supply chain and some of the steps we're taking to improve our processes across the value chain, including our buying and merchandising practices, as well as our compliance processes. We thought it would be helpful to map out the product journey before getting into the detail. Our sourcing model is based around speed to market. The benefits of a quick and reactive sourcing model are that we are continually stocking and restocking products which customers want. This keeps our brands relevant at the forefront of fashion, and we reduce waste that is prevalent in traditional retail models with excess inventory and unwanted product that's marked down. Product ideas are generated in three ways: our in-house design teams, who are coming up with unique products to reflect our brands, our buying teams, who are selecting products from multiple sources, particularly around social media, and our suppliers.
We have a very collaborative way of working with our suppliers, where they make recommendations based on what they're seeing in the marketplace. Once a product has been generated, a sample is mocked up by the supplier and agreed by the buying team. A purchase order is then generated, and the initial order is completed. Our sourcing model is centered around test and repeat, meaning we only ever trial a lower initial order quantity, typically 300 of a product. Once manufactured at factories in the UK, Europe, and Asia, the product is shipped as quickly as possible to our UK-based distribution centers in Burnley and Sheffield. We ship products in the most time-efficient way possible. Products reach Burnley from Leicester in a couple of hours, with air freight from Asia, meaning products land overnight.
The longest lead time will come from Europe, where it takes a few days to reach us by lorry. On average, our lead times are 4-6 weeks, and this includes our Asian manufacturers. We've also been investing in technology through the course of this year to enhance our compliance procedures. This technology will help ensure full compliance from an audit and product quality perspective, while also making our processes more efficient by reducing manual administration and paperwork. We have moved from a paper-based ordering system to a purchasing app. The app enables a simplified and digital order process, a single and real-time view of POs. It has an approved supplier list, meaning it's not possible to order from a supplier who hasn't been placed on that list and audited. Through this, it will ensure that any subcontractors need also to be approved.
We are also launching a new supplier portal. This is a one-stop shop for our buyers and suppliers to manage orders. It provides the buying teams with a single view of suppliers, including the ability to check their order status and certification. This will go one step further than where our ordering app is today by identifying where a product will be made and what the audit status is on that facility. Turning now to our new state-of-the-art manufacturing facility in Leicester. In June of this year, we purchased a former car dealership in Leicester. We plan to develop this as a center of manufacturing excellence in the city. The site is intended not just to be for Boohoo, but to be beneficial to the Leicester textile industry as a whole. As I said last week, this is not a move towards vertical integration.
Instead, our objectives for the site are to educate and demonstrate model manufacturing processes, to showcase how our products can be made legally, ethically, and safely, to work closely with the local authority and local organizations to drive investment and change in the region, to help nurture talent in the textile industry, working closely with local educational authorities to train new apprentices and provide opportunities for career progression. The site will create up to 250 new jobs and enhance skills in the local region. It will also provide a new office for our enlarged UK-based compliance team. We want it to be a community-oriented space, and we provide free access to other not-for-profit organizations. The site is expected to go live in 2021, and we'll provide further detail as our plans progress.
We're also keen to showcase the facility to our investors, analysts, and stakeholders once it's live. We have said as a group that we are committed to manufacturing in the UK and in Leicester, and we mean it. We are aware of our obligations to workers in the supply chain and the negative impact it would have on livelihoods by moving production elsewhere en masse. We will consolidate the long tail in our supply chain, working with fewer suppliers in more volume going forward. For example, while we had 200 Tier One suppliers, as per Ms. Levitt's review, the top 50 account for the significant majority of our UK volumes.
Consolidation of this base will allow some greater volume throughput to drive efficiencies and consistent order flows for our suppliers, and it will crucially allow for better oversight and governance of our suppliers in Leicester, which will remain a significant part of our manufacturing base going forward. This will, however, decline in our mix over time as we scale some international sourcing markets and expect our newer brands to increase in the mix, who do almost all of their sourcing from overseas markets. We are setting up a garment and textiles community trust. This will be governed by independent trustees, and we will provide it with startup funding and ongoing annual support. We will provide professional support to establish the trust's objectives and activities, including a grant-giving function to address hardship experienced by those working in the local garment industry.
Lastly, from a compliance, transparency, and governance perspective, we are committed to disclosing our UK supplier list. This will be done in the next 6 months. We are strengthening our sourcing team, including key hires such as our group responsible sourcing director, who has just started, and I'm excited about the difference he will make. We're establishing purchasing principles for our buying teams, who will receive mandatory education to help them better understand our supply chain and improve our buying practices. I thought I'd break down some of the things we are targeting over the next 12 months, including embedding our audit program with a complete auditing of all of our UK suppliers this financial year, disclosing our UK supplier list within the next 6 months, rolling this audit program out across our global supply chain, which starts with Bureau Veritas next week.
Set up our manufacturing center of excellence in Leicester, creating 250 jobs in the process and targeting 30,000-50,000 garments per week of production. More importantly, we will be using this as a hub to showcase processes for our suppliers and education and training to our teams. Launching our supplier portal, helping us to put technology into the heart of our buying and auditing functions, complete our global supply chain audit program and publish our global supply chain list, implement all of Miss Levitt's recommendations, further developing our sourcing and compliance teams, and completing our GBP 10 million investment across manufacturing, compliance, training, and education. As a board, we've always maintained a very open and regular dialogue with our investor. We've had extensive conversations over the last few months, and we have listened and taken on board your feedback.
In response to this feedback, as well as the finding of Alison Levitt's review, we are planning substantial enhancements to the board's corporate governance and oversight. This will include adding two new non-executive directors. We're advanced in our search for an audit committee chair and expect to be able to update you soon. We are also making progress with our search for a new board member with ESG credentials. Supply chain compliance becoming a mandatory item on every board meeting agenda with immediate effect. A new risk committee on the board, reporting into which is a new supply chain committee, headed up by our recently appointed responsible sourcing director, who joins us from a major global apparel retailer. We are close to appointing a highly experienced and respected individual to provide independent oversight of the implementation of our change agenda.
We also plan to work with external consultants more extensively in the future, particularly around the nominations and remuneration. Our non-executives, led by Brian Small, our Deputy Chair, will be undertaking annual roadshows to give shareholders the opportunity to have an independent discussion and voice their views. This presentation and our upcoming investor meetings will be a great opportunity to listen to our shareholders and take further feedback for communication going into 2021, and I'm very much looking forward to continuing that dialogue over the coming days. Now, I'm gonna hand over to Neil, who will walk you through the financials in relation to our supply chain. Neil will then talk you through what has been a fantastic first half of the year for the group.
As I already acknowledged, our teams have worked incredibly hard during the COVID-19 pandemic to maintain fantastic service levels and to keep delivering for our customers. We've delivered record sales and record profit, and I'm keen that that hard work is recognized today alongside the broader focus on our business. So thank you. I'll see you later. I will now pass you on to Neil.
Thank you, John, and good morning to everybody watching and listening. Before we move on to the financial review of the first half, I wanted to talk about some of the economic considerations that have been addressed in the Alison Levitt Review and in the lead up to it. I'd like to say, first and foremost, that everything I'm going to say is in the spirit of the findings of the review and also in the spirit of the recommendations from the review that we'll be continuing to implement in full in the coming months and the longer term.
I'd also like to say that as part of those recommendations, we're committed to driving real change in our supply chain, and that change will be to the benefit of all of the group shareholders, stakeholders, whether they be customers, employees, shareholders, and suppliers, as well as employees of those customers, shareholders, and suppliers. We all have a vested interest and a desire to ensure a sustainable future for the group. We want to support our suppliers and their employees in partnership as we implement the recommendations of the review. This will include making sure that working conditions and wages are fair for everyone in the supply chain, wherever they are in the world. So in that spirit, I'd like to address some perceptions that have been prominent in the last few months.
The review found that allegations of poor working conditions and low rates of pay in some Leicester factories are not merely well-founded, but substantially true. But the report also says that Ms. Levitt does not accept that Boohoo's business model is founded on the exploitation of employees in Leicester. And it also goes on to say that Boohoo and Leicester can flourish together. And with that in mind, we believe that the perception that products can't be sourced ethically and legally from the UK is not true, and that in reality, this definitely can be achieved. Our intention is to work with suppliers in accordance with the Alison Levitt Review's recommendations to ensure that the required standards for working conditions, safety, and fair wages are met globally. Some have suggested that if there is a reduction in our purchasing from Leicester, then our margins could suffer.
In reality, cost prices are much lower from other sourcing markets. However, we recognize the benefits of the speed to market that the Leicester supply base can give us. We don't want to lose that, but we're not prepared to sacrifice the safety, working conditions, and fair wages of anyone in the supply chain. Some have also suggested that our gross margins are higher than our peers for those reasons, and I'll show quite clearly that that's not the case. I'm also going to touch on the issue of the GBP 5 dress. Another perception is that we rely on the sale of low-priced items which can't be sourced responsibly. I'll show that low-price items represent a very small fraction of our business, and that we believe they absolutely can be sourced responsibly.
So on this slide, we've shown the landed product costings from overseas sourcing markets relative to the UK cost prices for the following items: a very low-cost short, a basic jersey top, and a pair of jersey bottoms. All of these items are below our average cost price for the Boohoo brand. And in all cases, the key point I'd like to make is that all of these garments require relatively little labor time to produce across all of the processes of cutting, sewing seams and hems, labeling, and packing. We should remember that several hundred items can be cut per hour, and for garments with a simple makeup, tens, and indeed, sometimes many tens of items can be sewn per hour by a skilled machinist. What this slide also shows is that sourcing all of these garments from overseas sourcing markets can be significantly cheaper versus the UK prices.
The overseas costings are based on factories in Morocco, Turkey, Bangladesh, and Pakistan, that also supply some of the world's largest and most reputable retailers, and that these are landed costs after using the appropriate transportation to reduce lead times to those associated with the test and repeat model. I'd also point out that fabrics overseas can be relatively more expensive, and what this means is that in some instances, a higher quality garment can be sourced from these overseas markets. So we could ask ourselves the question that if we're paying higher cost prices for UK-sourced garments, then how can we offer lower prices than the competition? This is also one of the perceptions we've seen or heard recently. The first part of the answer to this question is that we actually don't.
Our average selling prices for Boohoo brand are substantially higher than other retailers offering similar quality standards, such as high-profile price leaders in the UK, Europe, and the USA, and supermarkets with well-established clothing lines or brands. However, we can offer competitive prices compared with the largest high street brands, as our levels of markdown using the test and repeat model can be substantially lower. But as you can see on this slide, our gross margin is at the lower end of our peer group, as we offer great value in spite of those much lower levels of markdown. We should also state that our gross margin includes carriage revenues, which don't form part of product gross margins, and therefore, our product gross margins would be somewhat lower than we show on this chart.
As far as the £5 dress is concerned, what we've seen so far goes some way to show how dresses can be sold at low headline prices. But we should understand that for the Boohoo Group as a whole, this represents an extremely low proportion of our dresses sold. Here's the raw data for the Boohoo brand in the UK, and we can see that of 4.5 million dresses sold, only 370,000 were sold at £5 or less. That would include markdown items at the end of their life cycle, so the proportion that were initially merchandised for sale at £5 is much less, around 110,000 units, in fact. That's about 0.3% of our total units sold in the UK last year.
The bar chart on the right-hand side of this slide puts this in proportion and shows that by value, most dresses sold are in fact in the GBP 15-GBP 25 category, and much more dresses are sold above GBP 35 than GBP 5 and below. You'll also notice that the gross margin on dresses sold for GBP 5 or less is -12%, and what that reflects is the fact that most of the products are marked down at those price points or are lower margin loss leaders or hero SKUs that will be sold in an order with other higher price point items. So you can see that the reason we're famous for the GBP 5 dress is more related to our marketing strategy than a reflection of our impact on the environment.
We're at the end of this section, but I'd like to restate our views that, number one, our fashion is not disposable fashion. Secondly, we firmly believe that our products can be sourced ethically and sold at competitive price points. And finally, the UK supply chain will still have a significant part to play going forward as we look to be a force for good, to quote the Alison Levitt review, and improve the conditions and wages of all workers involved. So now I'm going to move on to the financial review of the first half. Here's the group income statement summary. The first half of the financial year brought a number of challenges posed by the onset of the COVID-19 pandemic. But in difficult times, we've delivered another exceptional set of numbers.
Group sales grew 45% to GBP 816 million, as we saw strong demand in all geographies. This was achieved with a healthy gross margin of 55%, an increase of 70 basis points on last year. Adjusted EBITDA came in at GBP 89.8 million, with a margin of 11% of sales, 20 basis points ahead of last year's 10.8%. At the EBIT level, we delivered GBP 79 million of adjusted EBIT, which was up 54% year on year, with adjusted EBIT margin up 60 basis points as we leveraged our depreciation and amortization expenses.
Adjusted items increased by GBP 4.6 million to GBP 11.3 million, due to an increase in share-based payment charges as a result of the inclusion of more participants in the group share schemes, as well as the management incentive plan announced in June. Adjusted diluted earnings per share increased 56% year-over-year to 4.53 pence. We expect earnings per share to continue to grow healthily through the second half of the financial year as we annualize the acquisition of the remaining 34% stake in PrettyLittleThing, which completed in May. The next slide shows our sales by geographical region. We've changed our segmental reporting to reflect the fact that our most important view of the business is by geographical market, and our primary objective is to increase market share in all geographies across all of the brands.
This is especially true now that we own outright all of the brands in the group. You can see from this chart, revenue growth was very strong in all regions. UK sales grew 37% in the first half of the year. That was an acceleration in growth from 30% in Q1 to 42% in the second quarter. That was a great performance against the increased competition as UK retail stores reopened in June and July. In the US, we've seen a standout performance, with sales of GBP 202 million, up 83% year-on-year. All brands are showing great potential in the US market, and lockdown gave us the opportunity to acquire new customers.
We've also seen encouraging growth in the rest of Europe region, reflecting our focus on certain key countries, and we continue to see healthy growth in the rest of the world segment. On to costs. Overall, we saw 10 basis points of deleverage, mainly due to increased distribution costs, which represented 24.3% of sales compared with 23% of sales in the same period of last year. While distribution costs have benefited from a reduction in returns rates, this has been more than offset by significant increases in international freight costs as we ship products to customers around the world since the COVID pandemic led to less passenger flights and increased demand for freight lanes.
Marketing costs reduced as a percentage of sales by 140 basis points to 7.9%, as we planned more cautiously on marketing campaigns in the early stages of lockdown, and we also saw strong returns from that reduced spend. Other admin costs were 13.1% of sales, up 20 basis points compared to the first half of last year. As we annualize increased investments into the new brands and their teams that were made in the second half of last year, and you can see in the graph that they actually improved by 60 basis points versus that period. On to cash flow. Cash flow for the group was extremely strong. We generated GBP 147 million of operating cash flow, driven by the group's profitability and a large working capital inflow.
With our negative net working capital cycle, although we were able to achieve a significant inventory build by the end of the second quarter. CapEx, at GBP 27 million, reflects increased spend related to infrastructure investments, and I'll come on to that in more detail shortly. Acquisitions of GBP 167 million reflects the buyout of the non-controlling interest in PrettyLittleThing, which completed towards the end of May for an initial consideration of GBP 270 million, and that was split GBP 162 million in cash and GBP 108 million in shares. We believe this transaction represented exceptional value for the group shareholders by doing this now rather than in 2022, and we have seen, and will continue to see, significant earnings enhancements for the group shareholders.
In June, we also acquired two womenswear brands, Oasis and Warehouse, for just over GBP 5 million. I'm pleased to say that these brands have been fully integrated and relaunched on our platform recently, and in the process of this acquisition, we've been able to create over 100 new roles which may otherwise have been lost. The group acquired GBP 25.7 million of shares for its employee benefits trust in order to satisfy future share option awards. In May, we raised just under GBP 200 million from shareholders as we look to make future acquisitions that can add value to the group and leverage investments in our multi-brand platform.
We ended the period with just under GBP 345 million of net cash, which is up GBP 138 million from GBP 207 million twelve months ago, and up GBP 104 million from the end of our last financial year in February. On to customer KPIs. It's been another period of improvements in these KPIs, with more customers being acquired and existing customers spending more frequently and in larger amounts with our portfolio of brands. The number of active customers in the last twelve months increased by 4.4 million versus the previous year, with a 34% increase in orders. Average order value was up 7%, with items per basket increasing 10%.
We're encouraged by the initial performance from the customers that we acquired in the lockdown period, and purchasing behavior in terms of aspects such as churn or speed of second purchase has been consistent with cohorts that we've acquired in prior periods. As far as CapEx is concerned, we're continuing to invest in our future with significant spend across warehouse and operations, our offices and IT systems, in order to give the group sufficient headroom to continue to deliver on its potential. We're increasing our CapEx guidance, now expected to be between GBP 80 million and GBP 100 million, up from our previous guidance of between GBP 60 million and GBP 80 million. This increase is as we accelerate investment programs to stay ahead of the growth curve.
As part of this, I'm pleased to announce a GBP 125 million automation project at our Sheffield site, which will increase efficiency, capacity and throughput, and will result in significant cost savings. The expenditure will span 3 financial years, culminating in the calendar year 2022, and the anticipated payback period will be between 3 and 5 years, and that's similar to our automation project that we completed in Burnley last year. By the end of that project, and along with other capacity expansion plans, we anticipate having warehousing capacity of in excess of 45 million units across the locations in Burnley and Sheffield, and that would equate to over GBP 3.5 billion of net sales capacity for the group. Lastly, on to guidance.
We've had a very strong first half, and momentum has continued into September, at the start of the second half. That said, there's still a long way to go, and we're cautious about the backdrop of the COVID-19 pandemic and the impact that this could have on the peak trading season. So far, along with other online businesses, COVID-19 hasn't impacted sales negatively, and indeed, at times during lockdown, we've seen a boost in certain areas. Distribution cost increases have been offset by the benefits of lower returns rates. However, it's prudent to plan for the rest of the year to be mindful of the highly uncertain economic and consumer outlook, as well as the unique challenges posed by the COVID-19 pandemic. Taking all of those factors into account, we're upgrading our sales growth guidance to between 28% and 32%.
We expect adjusted EBITDA margin to be around 10%, and that's up from our previous guidance of between 9.5% and 10%. That guidance is also prudent in that it anticipates ramping up marketing spend in the second half, continued headwinds on shipping costs, and the fact that returns rates could increase to the levels that we saw before the pandemic. CapEx will be in the region of GBP 80 million to GBP 100 million, as I've just mentioned, and we expect our effective tax rate for the full year to be 22%. Adjusting items of approximately GBP 23 million is split between the amortization of acquired intangibles of GBP 4.5 million to GBP 5 million, with the balance being share-based payment charges. Our medium-term guidance of 25% sales growth per annum and an adjusted EBITDA margin of 10% remains unchanged.
We're committed as a group to continue to invest across our business and into our people, infrastructure, and supply chain to deliver industry-leading rates of growth, and we remain excited about the group's potential. We have flagged previously an incremental investment of GBP 10 million into our supply chain, and we do not expect this to impact our guidance. Likewise, as we continue to grow and scale, we will also see growth from international sourcing markets with a potential reduction of the UK sourcing mix. We expect the net effect to be neutral to gross profit margins without sacrificing lead times, so this should support margins in the future. On that note, I'll pass over to Carol, who's going to run through developments across the brands that have happened in the last six months. Thank you.
Sanitizing my hands. So thank you, John, and thank you, Neil, and good morning, everyone. This morning, I'd like to give you an update on our brands, but before I do so, I'd just like to reiterate some of John's words. As the co-founder of Boohoo, I'd like to stress how incredibly seriously we're taking the findings of the independent review. We care deeply about the influence we have on, as a group, on the UK manufacturing industry, and I want to stress how committed we are to doing things better and to be more transparent as we work through improvements to the way we work with our suppliers. I have absolute confidence in the ability to be a positive influence for change. On a lighter note now, I'm going to turn to what our brands have been up to for the last six months.
Six years ago, we floated with just one brand, Boohoo, and now with nine brands, we're very excited about the opportunities that lie ahead. In June, we welcomed both Oasis and Warehouse to the Boohoo family. Adding to our other recent acquisitions of Karen Millen and Coast, we now have a portfolio of strong British heritage brands, complementary to those value brands we have already established firmly in e-commerce. I'm also going to be covering off our evolving customer demographic and how we're repositioning our newer brands to make them more accessible to a wider audience and relevant to modern-day shopping habits. As usual, I'm now going to play you a short video showcasing what our brands have been up to in the past six months.
So as you can see, there's lots going on, and, quite incredible what our teams have managed to achieve in what's been a very challenging year for all of us in retail. Now, at 9 brands, our recent acquisitions have significantly extended our target market, with entry prices starting at GBP 3 on our, in our value brands, and exit prices at 1,400 GBP in our premium brand, Karen Millen, and lots of varied product in between. We feel now we're in a position to offer real choice for all our customers. We now target young women and men from the age of 16, and with the addition of our newer brands covering off the middle and the premium market, we now extend our customers to the age of 45 and above.
On previous updates, I've talked in detail about our established brands, Boohoo, boohooMAN, PrettyLittleThing, Nasty Gal, MissPap. Today, I'd like to take this opportunity to update you on what we've been doing on our more recent acquisitions, Karen Millen and Coast, both acquired in August 2019, and Warehouse and Oasis, acquired in June this year. They're all heritage British brands. Warehouse was established in 1976 and Karen Millen in 1981, so they have lots of brand awareness. Buying them out of administration, we've also been able to continue that fantastic heritage of what may have been lost otherwise. The opportunity to develop them and their market is... The opportunity is immense as we take them from large bricks-and-mortar retailers to pure-play online retailers, with all the global opportunities that will present themselves in the future.
Of course, we'll maximize their already developed brand identity and all that British heritage. For all our brands, social media is one of the larger channels for us to communicate with both our customers and our following. Now, with 28 million followers across Instagram and 36 million across all our social media channels, the past six months have seen a complete change of approach with the lockdown period. Big events, larger collaborations have been a challenge. However, this hasn't stood in our way. We've still worked with celebrities and highly regarded influencers, and now with a portfolio of brands that this has just spread the net even further, to the extent we're now creating relevant content for lots of consumers of all ages.
Of course, each brand has its own signature style of their own, and it's very clear through all the con-content we produce which brand is which. So just to name a few, Boohoo enhanced the TikTok craze with its recent Move Me campaign, taking a TikTok format to our TV screens with dance choreographer Kristiana Rianna. boohooMAN strengthened its athleisure range when it collaborated with US rapper Swae Lee. PrettyLittleThing collaborated with Alexis Stone, a makeup and drag artist, for Pride. Nasty Gal put edited collections together with Paris Jackson and Brittany Xavier, both global influencers, and I'm happy to announce a new collaboration for Nasty Gal just next week on the seventh of October with EmRata. At MissPap, a collaboration with Missy Keating, a model and TV presenter. Karen Millen's also now started on its influencer journey with influencer Lydia Millen, no relation.
Coast, a collaboration with Amy Neville, styled by TV presenter Mark Heyes, and of course, there's loads more to mention. With all these nine brands, we're now covering off what is a much wider demographic, with a clear focus now from the 16- to 45-year-old age group. Our youthful brands of boohoo, boohooMAN, PrettyLittleThing, Nasty Gal and MissPap, acquiring customers from the age of 16 to twenty-somethings, appealing to the fashionable and value-conscious customers. However, you can see from the chart, the reach of these brands extends to both younger and older customers, reflecting the breadth of our product ranges. Coast, traditionally, has been a, an occasion-wear brand. This range is evolving, and I'll cover that off in a coming slide.
It has the broadest target market, from teenagers buying prom dresses and then onto bridesmaid dresses, and then forty-somethings, year-old women may be buying an outfit for the race, for the races. Karen Millen has a very clear, target market of the age of 25- to 40-year-old professional women, but it's also attracting younger and older customers. Both the new acquisitions of Warehouse and Oasis, which are just bedding in, have further extended the representation of our target market to that 25- to 40-year-old customer. The ambition is simply growing our portfolio of brands. We're able to capture an increasing share of wallet, keeping our customers for longer and shopping within the group. This chart demonstrates how we're positioning our recent acquired brands, making them more relevant and trend-led than ever before.
Our established value brands are largely similar, in that they're all targeting a fashion-conscious customer at the value end of the market. Karen Millen, however, our premium brand, we have reduced its price point and made it more affordable than the old Karen Millen, but at the same time, increased its fashion authority, bringing a broader and regular world product updates. Coast, we have also reduced its price point, while maintaining its occasion wear feel and further injecting new casual ranges. For Warehouse and Oasis, the plan is very new. The price points will largely remain unchanged, but there will definitely be a shift to making both these brands more trend-led. Warehouse, for now, I'm going to refer to it as our London rock 'n' roll brand. It's edgy and very fashion authoritative.
Oasis, also trend-led, but with a much softer feel, a more soft, feminine feel, I'd call it. And now I'll come on to talk about both of those in the coming slides. So turning to what we have achieved on Karen Millen and Coast, we're now one year on and achieved so much, considering part of this year we've been in lockdown. It's been really encouraging, achieving so much when it feels like all the odds were against us with Covid. We really are disrupting the market with these newer brands, offering fantastic quality to quality tailoring, amazing dresses, occasion wear at Coast, luxury loungewear for working from home, a huge achievement, achievement in just a short period of time. We launched Karen Millen with just 60 styles a year ago, and we're now carrying 1,500 options.
When Karen Millen used to stock about 500 products a season, we're now launching 150 new styles every single week. We've proved that the concept that our test and repeat formula can work with offshore production on premium products, taking our previous 6- to 9-month lead time down to 6- to 8 weeks. And at Karen Millen, we've extended the product ranges and just recently introduced Curve, making the brand yet more accessible to more customers, carrying more sizes. Design and product development sits at the heart of Karen Millen, with a very talented and buying design team. Investment dressing is key. The product offering with pieces that are still relevant today, as they were many years ago, like our Forever Dress. Buy it today, and you'll still be wearing it for years to come.
In addition, we've added new product categories like loungewear, accessories, and jewelry. On Coast, historically an occasion wear brand, we're extending the ranges to transform into a pure play that will have something for everyone from morning to day to night. Lots of new casual ranges, loungewear, footwear, denim, T-shirts, et cetera. It's a real move forward, and the recent campaign with the tagline, "Fashion for all womankind," was launched this summer. Both brands have launched their on TV for the first time this summer, and we've started on their journey to working with influencers and fashion stylists. We've seen a fantastic response from traditional press and lots of product placement on leading celebs. Our most recent additions to the group, Oasis and Warehouse, acquired in June.
We did a soft launch in July, and just recently, mid-September, launched both of the websites onto our platform. The integration has been very similar to Karen Millen and Coast. Perhaps a little easier, we already had our learnings from last year, and we've now taken on, as Neil said earlier, over 100 employees from the original teams, and that's really to ensure the continuity of the brand image. It's early days, so not too much to talk about as yet, 'cause we're just a few weeks in, but I'd like to give you a flavor of the brand identity and what to expect. With Oasis, we're targeting that everyday woman, and that's a really big audience to go for, one we're very excited about. Her wardrobe tells a story of color and print and feminine fashion.
Soft and easy-to-wear pieces for every occasion, from florals to sharp tailoring and lace to leather. The brand has an overriding feel of a confident woman curating her own personal style and one that is of sophistication and femininity. Our Warehouse woman has more edge. Her style is more urban, with strong London roots, and she travels to cities like Berlin and Paris and Milan. Her style, as I said earlier, it's certainly more rock 'n' roll. Think leather and studding, floral dresses with an oversized coat, messy hair, and a smoky eye. It's a brand that I kind of aspired and always wore through my twenty-something, I think. But her identity is really about late nights, bright lights, and all that the big cities bring. So just a final word from me.
We have achieved so much in what has been very challenging months in so many ways. Our ambition and our plans haven't changed, and we are looking forward to dressing all women around the world one day. And on that note, I'm going to hand you back to John. Thank you.
Thanks, Clara. Thanks for that. So just a summary from me. So it's been a longer presentation than normal, but I wanted to take that time to provide further detail around how we're developing the group's sustainability strategy, demonstrate our commitment to greater transparency, show how seriously the board is taking the findings of the independent review. I want to reiterate the board's commitment to driving the agenda for change in UK manufacturing. As part of this, we will be making significant enhancements to our corporate governance and supply chain compliance processes. I look forward to updating you on our progress against Miss Levitt's recommendations over the course of the next twelve months. We should not forget that we have a very strong platform through which to deliver change. We are in a very fortunate position to be growing strongly and profitably.
We're close to exceeding GBP 1.5 billion of sales over the last 12 months, which is a huge milestone for the group, having hit GBP 1 billion of sales this time last year. We now have nine 100% owned brands, and we're targeting much wider demographic of 16- to 45-year-olds. Our recent acquisitions of British heritage brands have helped save and create over 200 jobs. We have a strong cash position and continue to look to grow through further M&A as well as our own brands. It's an exciting time for the group and our stakeholders. We're looking forwards with a strong financial position and strong mindset for change, which should create not just a leader, but a sustainable leader in fashion e-commerce. So, Andrew, would you like to start the Q&A?
Thank you, John. So first, two questions today from Aneesha Sherman at Bernstein. Do you expect you'll use more ground freight in the second half of the year to offset the rising cost of air freight? And what impact would that have in terms of lead time? And the second question, with regards to the supply chain review and audits that are going on, when would you expect that to conclude for the UK and be in position to have a fully compliant UK supply base?
Okay, so I'll take the one with the UK audits. We hope to have the UK audits complete by the end of this financial year. Then, as I stated earlier, we hope to be able to publish a full list of our UK supply base in six months.
On the freight question, we're not really anticipating more ground freight over the next coming months. But we'd look at that if it made sense financially, but also from a lead time perspective. So we're continuing with air freight, and the main increases in costs have been on the outbound side, so delivering parcels to our international customers, particularly in the US and some of the further afield territories. And those costs are likely to remain higher. But as we progress through to the other side of the pandemic, we should go back to more normal levels. But it's quite uncertain as to how that's gonna pan out.
But, note, on the inbound side with product, we'll continue to use air freight as we, as we have done.
Okay, next question from Matthew at N+1 Singer. Please, could you elaborate on the benefits from lower returns rates? Roughly, how much did it add to the net sales growth in the period, and how much of this was a function of category mix versus consumer buying habits changing?
So I can take that question on the financial side of low returns rates. And it really depends how you look at it, but I don't look that net sales growth has been aided by lower returns rates, 'cause what we're doing is we're sending parcels out there. Less have come back because the customers like the product for one reason or another, or haven't returned it for one reason or another. What you do when what happens when people do return products is they don't return order something else to replace that. So it doesn't really boost sales growth as such, and so I wouldn't quantify that. What it does do is enable you to leverage your distribution costs more effectively, so you haven't got the costs of bringing as many customer goods back.
And you also don't have the costs of then sending out those additional items that people are ordering in the place of it. So it's a more efficient supply chain with the customer. That's the benefit of returns rates. And so that's the way I'd look at that. The best way to quantify the impact of the efficiency is by looking at the distribution costs and what those have been as a percentage of sales. But all I'd say on that is that we've seen deleverage on distribution costs because of those higher shipping charges.
But we've those higher charges have been offset by a benefit in distribution costs from the lower costs associated with returns, and potentially that deleverage could have been a bit higher, about 1 percentage point higher if we hadn't seen the lower returns rates.
Okay, next question from Simon Bowler at Numis. Can you give a sense of how much focus and attention is on continued M&A? And secondly, can you give a sense of margin impact from that lower returns rate, offset by the higher freight costs?
... Should I take the M&A one? I mean, look, we've been very clear in the summer with regards to the monies we've raised, just under GBP 200 million. We purchased Oasis and Warehouse for GBP 5.25 million, which clearly has a good balance outstanding in terms of for further M&A. We're looking at M&A globally, not just in the UK market, but in Europe and the USA. It's one we have been, it's one we'll continue to look at, and we think there will be opportunities.
On the margin impact of the lower returns rate, obviously, it doesn't impact our gross margin, as such, and, I've just spoken about the impact on distribution costs, where we've seen higher distribution costs were offset by that benefit of returns rates, lower returns rates.
Okay, two questions now from Wayne Brown at Liberum. Just firstly, with regards to Leicester being a significant part of your supply chain, how are you confident that the gross margins aren't under threat from the supply chain review? Second question is, just in terms of your gross margin dynamic, you source from a high-cost sourcing market in the UK, and how are you able to achieve a comparable gross margin versus your peer set?
So we've spoken a bit about those two points in the presentation, actually. But on the gross margin impact of any investments we're making in Leicester, as we're getting bigger and scaling, you get benefits from scale generally through your sourcing. And that's why the guidance that we've given on the GBP 10 million operating cost is not necessarily going to impact our gross margin. Now, obviously, we first and foremost want to work with all of the suppliers in Leicester to make sure that we reach the required standards. If there are impacts on cost prices that can't be offset by efficiency in their operations, which I think there's definitely potential to do that, so that's going to help as well.
But what we do anticipate from the review, and it's clearly documented in the review, is that there will be a kind of rationalization of the number of suppliers in Leicester. And therefore, what we can do is offer the suppliers that are able to work with us going forward more consistent volumes of order throughput, and that will lead to some quite high efficiency gains for everybody. And that's going to be a positive impact, we hope. And we're confident about that.
And then, as we maintain volumes as much as we possibly can in Leicester, we're also, and this is happening, we'll be growing our sourcing overseas, and as we saw in the presentation, that can have significantly higher gross margins, bought-in gross margins. And if we can achieve similar levels of lead time that we do with the UK supply chain, then we also have low levels of markdown with those products. So overall, we're saying, and we said it quite clearly, that net, we think those puts and takes are going to be neutral on our gross margin going forward.
Okay, from David Holmes at Bank of America. Can you comment on the Q2 slowdown in the rest of Europe? What drove this?
On the Q2 slowdown in the rest of Europe, that was what we saw in selected markets, just what happened as those markets came out of lockdown. So we've seen some superb growth in Q1, and then the market started coming out of lockdown, and we felt that some of the customers in certain European markets did go back to the high street stores. I think we've probably seen that in some of the results that other retailers have provided. And then, in addition to that, our shipping times were slightly elongated in Q2, so hopefully we'll be able to remedy that as we go forward. I think people will get back in those markets to more normal patterns, embracing online shopping.
Okay, Ben Hunt at Investec with two questions. The implied H2 sales slow down from your guidance, how much of this anticipates supply chain disruption? And secondly, does the significant inventory build-up at the half year reflect confidence ahead or provisions for potential supply chain disruption?
The implied slowdown in the second half guidance is really about what could happen and prudence, and therefore, with the backdrop of COVID-19, there's a lot of economic uncertainty out there, and therefore, what is going to happen to demand through the Christmas party season. So we want—it's sensible to be prudent in these unprecedented times, I think. In terms of supply chain disruption, we've not necessarily factored that in to the guidance. We're not expecting our supply chain to be disrupted in the second half of the year. But it's—I think it's sensible to assume some impacts of the pandemic, but not on the supply chain disruption side for us. If there's...
It does factor in caution generally, and you could argue that supply chain disruption, i.e., slower delivery times to certain markets, are factored in there, but that's not a material part of the guidance. But overall, the guidance is prudent. I think it's absolutely sensible to do so in this environment.
Okay, three questions from John Stevenson at Peel Hunt. On your U.S. sales growth, which, which brands have, have driven this? And does this change any of your thinking in terms of international distribution, development, and timing? Secondly, from a marketing and collaborations perspective, have there been any delays to campaigns through the first half of the year? And third question, can you give some sense of brand-by-brand performance or growth highlights?
So maybe should I take the U.S. sales growth? So that's really been very strong. Of course, our key brand's already trading in the U.S., and that is obviously Boohoo, PrettyLittleThing, and Nasty Gal. In terms of the kind of thoughts or whatever around distribution center, we're coming towards the end of a piece of work there regarding our first international distribution center. So that's something we'll be kind of getting to a decision on in the next couple of months, really, I would say. In terms of third question, do you want that?
Marketing collaborations.
Marketing collaborations.
Yeah, I, I can take that one. On the... There's been no real delay as such. We have got some campaigns in the pipeline. I did mention on Nasty Gal, the EmRata one that launches just next week. But I think it's been because of the lockdown. It's been; we haven't been able to facilitate a lot of the big, larger collaborations we would have normally done with the large events and things. So it's been less of a delay from either side, but actually more of a choice not to go down those channels because we didn't feel we could maximize the exposure, shall we say, without events as a result. And you know, it might have just been money that wasn't well spent.
I think as we're going into this part of the next season, we've got one or two lined up, which we'll be able to get back onto that path. But, you know, we're very open to changing all our marketing channels, and I think this is where we're extremely agile as a business, is to be able to stop things and restart things, depending on what's happening around the world with COVID-19.
Okay, two questions from Alvira at Barclays. Why do you historically source from the UK if it is significantly more expensive than other markets? And secondly, can you provide any color in terms of the shape of trading in Q2, and was there anything in particular to call out?
So, I think in terms of the historical sourcing in the UK, I think it's been convenience, it's been speed, it's been the test and repeat model, which effectively is buying closer to the season, therefore a higher cost price, but clearly a reduced markdown in terms of what we're doing. We've sort of... As we've grown Boohoo, but equally as we've grown the multiple brands, what we are obviously is trading into new categories of denims, et cetera. So that earlier quote around sort of 70% back at IPO, down to 40%, probably going to about 20% in the near future, is about sort of category growth, product growth, but equally the brand acquisitions that we've put on as well.
I think on the shape of trading in the UK in Q2, it was very consistent, actually. Strong growth across all, all of the brands through the quarter. What we did see, if you go back as far as April and May, was extremely high growth after an extremely low growth in March. And then as we advanced through the lockdown stage, and lockdown restrictions were eased in May, June, July, and August, then we went back to more normal levels of growth, should we say, but still higher than we'd probably expected, coming into the financial year before the pandemic came around.
But it was very consistent and so, through those three months that after lockdown restrictions were eased and the high street stores came back online, there was a little slowdown, but still great growth in the UK. It was very pleasing to get that level of acceleration from Q1 into Q2.
Okay, three questions from Georgina at J.P. Morgan. Will a change from the re-review be to bring more design in-house? Can you maintain your UK margins while looking to work with higher skilled workers in Leicester? And lastly, is there any reason why the lead times on Karen Millen are a little bit longer than your kind of group average of 4-6 weeks?
So, first one first, is in terms of design in-house, actually, we've been continuously increasing the numbers of designers in-house. It's a key part of a fashion business, and with fashions changing so quickly. With regards to the Karen Millen point, Karen Millen garments are just much more sophisticated in terms of much more detailed garments requiring different fabrics, and as I said, details, whether it's delicate fabrics you're working with, to stitching, buttons, pockets, et cetera, on that one.
In terms of the UK margin, I'll just kind of refer back to the kind of Neil's points that he's been making in the morning about kind of as we consolidate, particularly that Tier Two, it's around driving more volume and more efficient volume through a smaller number of suppliers, and we think we'll get the efficiencies out of that to maintain those margins.
... Okay, a question from Charlie Muir-Sands at Exane. Your period-end inventories are ahead of your implied H2 sales guidance. What gives you confidence there won't be a clearance problem?
So we're prepared for everything with the inventory build that we've done, and we actually felt at the end of August, and that's been kind of validated coming through September, that we've got a great product offering across the brands to cope with anything that the COVID pandemic throws at us. And I think that's what you're seeing in that stock build. And actually back in earlier on in April, May time, we would have wanted those levels of inventory to be able to offer the customers as much choice as possible. And we've got that back into a better place.
But it's not at such a level that if we see any kind of downturn in demand in the market because of macro factors, that it should lead to a clearance problem. So we actually feel like we're in a great position as we sit here today, with the stock package and the flexibility that we've got, with that to trade well through the peak season. But let's see what happens. There's a long way to go and a lot to happen between now and the peak trading period.
Okay, we've got a couple of follow-up questions from Simon at Numis. Can you give a sense of contribution from the acquired brands in the first half performance? Can you provide any more color in terms of marketing efficiency in the first half? Was this a bit of a one-off benefit that will normalize in H2? And lastly, in terms of Brexit, can you make any comments in terms of preparation and risk management?
Okay, I missed the middle question there, but on the acquired brands, we've been really pleased with their performance in the first half of the year. We would have liked to have done more on the marketing side to get them to improve even more. But I think, if you look at Karen Millen and Coast, they look like to have been the strongest acquisition that we've made, and we're kind of comparing there to the relevant revenue stream coming into the acquisition. So if I looked at Nasty Gal, the relevant revenue stream was, it did before the year before the acquisition, about GBP 25 million of sales in own brand products, and we were able to meet that, in the first year of acquisition.
For the relevant revenue stream for Karen Millen and Coast was around GBP 30 million of online revenues. I think we're going to beat that this year quite reasonably significantly. And so far, they've been contributing at the pro forma EBITDA level. But that's not really what we wanted to do, and we're expecting a single-digit million pounds investment in Karen Millen and Coast and the other acquired brands over the year as a whole, as we're able to now put that effort into marketing them going forwards now that we're in a more normal situation in the market. What was the middle question, Alistair?
Middle question was just, can you provide more color on the marketing efficiency in H1? Was that COVID benefiting, and do you expect it to normalize in H2?
You've seen about 130 basis points of leverage on the marketing costs compared to last year. And that was really as a result of our marketing approach through lockdown, et cetera. So, as I said in my presentation, we saw good returns on the marketing spend across the board through that. So, that's what you've seen. Now, in H2, we're anticipating in the guidance that we get back to more normal levels that we've seen before the pandemic for marketing spend.
We're keen, not just with the new brands, but with all of the brands, to make sure that we're at the right level of marketing spend, but we'll still be at a good point on the diminishing returns curve, but I'd expect it to go up as a percentage of sales in H2.
Just the final question from Simon was in terms of Brexit and risk management.
So we're doing what we can to plan for Brexit. And of course, a lot of political happenings are gonna happen over the next few weeks. But we've been putting a lot of effort into planning the supply chain, should there be a hard Brexit. Hopefully, that won't be the case, but that's where we are. We're just, as everybody else is, just trying to plan as best we can. Time's running out before we actually the end of the transition period, if you like, at the end of the year. But we're really putting a lot of focus into that at the moment, planning for the end of that transition period.
Okay, and, there's a follow-up question from Liberum. If you upskill your UK supply, will you start sourcing more complex and tailored products from the UK?
I think the benefit of some of those more complex garments in the overseas market is actually the fabrics and the fabric mills are in those overseas. So you're taking that from the overseas markets to get it to the UK, and that's why the UK, at the moment, works on these more simple garments. So, you know, for example, to make a pair of jeans in the UK would be very difficult because fabric, et cetera, would need to come from overseas, the processes, et cetera, of getting jeans. So we're definitely looking to see how we can make further and more complex than what we do today.
That may be by, for example, maybe more detailed printing processes, maybe perhaps more embroidery type of attachment, maybe garments where require more pockets, et cetera, zip detail, button detail, et cetera. I think that's where we'll start, and then we'll see where it will go to.
Just a final question, what makes the board confident looking ahead?
I think, in terms of everything we've achieved in, the last 6.5 years since our IPO has been very, very successful. We've overcome, the past 6 months in terms of COVID-19 and, you know, continued to keep the business growing, continued in the M&A field of acquisition. We clearly have work to do regarding, compliance and our supply chain. But equally, you know, as we've done in other areas of our business, we're very, very confident we can achieve that and deliver on that.
Okay, there doesn't seem to be any more questions, so back to you, Carol.
Perfect. All right, thanks, Alistair. Just a final note from me and from Carol and from Neil here today, just thank you so much for watching us today. We know it's been extended, but we felt we had a number of topics that we wanted to cover in more detail than usual. And again, just again, from the board's point of view, absolute confidence in terms of everything that we spoke about today, delivering on it, and making sure that it's delivered in a timely format as well. So thank you and goodbye.
