As today's live webcast of our 2024 half-year results, your hosts will be Dolf van den Brink, our CEO, and Harold van den Broek, our CFO. Following the presentation, we will be happy to take your questions. The presentation includes forward-looking statements and expectations based on management's current views and involve known and unknown risks and uncertainties, and it is possible that the actual results may differ materially. For more information, please refer to the disclaimer on the first page of this presentation. I will now turn the call over to Dolf.
Okay, thank you, Tristan. And before we start, welcome to the team. And I also wanted to personally say a big thank you to Federico, who is here with us in the room. After seven years as an IR director, he will be moving to be our new finance director in the Netherlands, and I want to wish him a lot of success. Thanks, Federico. So, welcome, everyone. We delivered a solid first half of the year, demonstrating progress on our multi-year transformation strategy, EverGreen. Before we delve into the results, let's start with a brief reminder of our strategy, which continues to shape our business. Our ambition is to deliver superior balanced growth to consistently create long-term value. And we do this with a clear focus on our five strategic priorities embedded in the business, as indicated on the left. These priorities propel the flywheel of our growth algorithm.
We set the top first and foremost growth. We are after superior balanced growth, both volume and value growth. Growth enables gains in productivity and fuels resources for investing in future growth and to improve profitability. We delivered on this in the first half, and we will double down in the second half of the year by reinvesting significantly more of our cost savings behind our brands. We're on track and working towards sustainably delivering the balance embodied in our Green Diamond: growth, balance between volume and value, continuous productivity, better capital efficiency, and realizing our ambitions on sustainability and responsibility. So let's take a closer look at the results highlights. We achieved a solid first half of the year. Net revenue BEIA grew 6.0% organically versus last year.
Significantly, our growth was balanced and broad-based, as net revenue per hectoliter BEIA grew by 4.3%, while total beer volume was up by 2.1%. The momentum behind Heineken brand accelerated to grow 9.2%. Operating profit BEIA grew by 12.5%, and the margin was 14.0%, up 60 basis points versus last year. Notable was the strong improvement in the Americas. Net profit improved by 4.4%, with the operating growth partially offset by higher financing and tax expenses. Diluted EPS ended at €2.15. Harold will cover this in more detail later. The delivery of our growth in the first half has been balanced, and moreover, the volume growth itself has been of high quality. Our premium beer brands grew 5%, more than double the rate of our total beer portfolio.
The growth has been delivered BEIA wide range of premium brands and extensions across our regions, including Kingfisher Ultra in India, Birra Moretti in Europe, Dos Equis in the Americas, and Desperados in Nigeria. Of course, led by Heineken, which was up more than 9%. The growth was broad, with 27 markets in double digits, most notably in Brazil, China, and Vietnam. Additionally, our non-alcoholic beer and cider portfolio grew close to 10%. I will expand on our leadership position in this segment later in the presentation. This high-quality volume growth led to 6% net revenue growth, with positive price mix in all regions, particularly Africa and the Middle East. Operating leverage led to a good revenue-to-profit conversion, as the growth in operating profit was more than two times the growth in net revenue. Now, let me take you through the performance in our regions.
First, Africa and the Middle East, where we achieved volume growth under challenging conditions and landed the pricing required to offset inflation and currency devaluations. Net revenue grew organically by 27%, with 1.5% beer volume growth and a strong price mix of 24%, mainly by pricing for inflation. Operating profit grew 21%, as pricing, volume growth, and continued productivity gains more than offset inflation and the impacts of devaluations in our costs. In Nigeria, net revenue grew disproportionately with steep pricing to mitigate the impact of inflation and the Naira devaluation. Despite difficult economic conditions, volume grew in the mid-teens, led by Goldberg, Life, and our premium brand Desperados. We're reshaping the balance sheet of Nigerian Breweries to set it up for sustainable future growth, which Harold will explain later. In Ethiopia, revenue grew in the mid-teens as inflation-led pricing more than offset the volume decline.
There is continued civil instability in key regions of the market. Consumer purchasing power remains under pressure from the effects of hyperinflation. Last night, the Ethiopian government announced an economic reform program, which we believe will be good for the country's long-term prospects. In South Africa, we achieved the first-year milestone integrating the Distell acquisition, enabling a competitive multi-category business model to capture the growth. Our wine, Distell, Spirits, Cider, and Ready-to-Drink portfolio outperformed the market in their respective categories, led by the continued momentum behind Savanna and Bernini. We have more work to do in the beer segment and are excited about the prospects for the 65-cent returnable glass bottle for Heineken introduced in the first half. On to the Americas, which really stood out in the first half in its strong operating profit performance. Net revenue grew 4% and beer volume up a percentage point.
Price mix grew by 4%, driven by pricing and premiumization. Operating profit beia grew 37%, driven by the top line and significant improvement in variable expenses, benefiting from near-shoring initiatives, lower transportation and commodity costs, and favorable transactional currency effects. In Mexico, revenue increased organically by a mid-single digit, driven by volume growth and revenue management initiatives. The volume growth was led by our core portfolio brands, Dos Equis, our affordable premium position, and Indio, the mainstream segment. Heineken 0.0 grew volume by a mid-single digit and remains the number one non-alcoholic brand in the market. In the USA, sales to retailers outperformed the market. Heineken's brand power continued to improve, supported by Heineken Silver and Heineken 0.0 , which recorded its 19th consecutive quarter of growth. Dos Equis continued its positive momentum across the Sun Belt and is the number one brand in draft in Texas. In.
Leadership position in the premium segment. Amstel grew in the low, gained market share in most of our markets, most notably in the UK, led by Birra Moretti, Beavertown, and Cruzcampo, our authentic Spanish mainstream lager from Seville, which became the largest launch in the off-trade in more than a decade across beers, wines, and spirits. Premium beer volume outperformed our broader portfolio, led by Heineken and our next-generation brands such as Birra Moretti, Gallia, El Águila, Messina, and Texels. The non-alcoholic beer and cider portfolio grew by a high single digit, led by Heineken 0.0 . Moving on to brand Heineken, leading our portfolio. The sustained momentum behind Heineken continues apace. The innovations of Silver and Zero Zero have been additive to growing the brand power and the volume of Heineken Original. In the last five years, we have grown volume by 50%.
This continues into 2024, in the first six months adding another 9 percentage points of growth, with 27 markets in the double digits, most notably in Brazil, China, and Vietnam. Heineken 0.0 and Heineken Silver have been once again strong contributors, up 14% and 41% respectively in the first half of the year. I'm also especially proud that the Heineken brand continues to be admired for its creativity in both idea and execution. Heineken was recognized as the number one most creative brand in the alcoholic drinks category and the number two most creative brand across all categories at the prestigious Cannes Lions Festival of Creativity, taking home a record 22 awards. Let's zoom into Zero Zero for a moment. We are the global leader in non-alcoholic beer, a category that delivers growth, profitability, and moderation.
Our share of non-alcoholic beer is 1.5 times our share in total beer, and we have captured half of the total global growth in non-alcoholic beer over the past five years. We have achieved this on the back of Heineken 0.0 , the largest global brand in Zero Zero, revolutionizing the category. It's now available and admired in 115 markets and grew by double digits in 23 markets in the first half. Specifically in the U.S., Heineken 0.0 has had 19 consecutive quarters of growth since its introduction. Moreover, we continue to introduce Zero Zero variants of our key brands, among more recently Schin 0.0 in Brazil and El Águila Sin Filtrar 0.0 in Spain, and broaden the range of Żywiec 0.0 flavors in Poland.
Moving to our next strategic priority, digital, we aim to become the best-connected, the most relevant brewer for our customers, and the focus first and foremost is for the beer category and our portfolio to grow our customers' businesses. We are unlocking incremental value for our customers through our digital ecosystem, eazle, which expands our market coverage and enables better service. By the end of the first half of the year, we captured over EUR 6 billion in gross merchandising value on our digital platforms. We now connect almost 650,000 active customers, accounting for close to two-thirds of our customers in fragmented traditional channels globally. And of course, we grew a better world to our strategy to deliver on our environmental, social, and responsibility ambitions, where we are progressing across all three pillars.
In our ambition to achieve net zero carbon in Scope 1 and 2 by 2030, we continue to make progress and have further reduced our emissions in the first half of the year. For example, we opened a large-scale solar thermal plant in Valencia, Spain. On our journey towards healthy watersheds, we have further improved the water use efficiency in our breweries and now have over 32 water balancing projects, most recently adding the production sites in Meoqui in Mexico and Gitega in Burundi. On the social pillar, we are on track to achieve our target of at least 30% women in senior management roles by 2025 and 40% by 2030, with good progress this year. On responsible consumption, as I indicated earlier, as category leaders, we continue to make progress to make sure that zero alcohol options are always a choice and broadly available.
Before I hand over to Harold for the financial highlights, I would like to recognize the efforts of our team at Heineken. We've had a solid start of the year, returning to balanced top and bottom line performance. EverGreen strategy has been and continues to be our compass, and I'm proud of the progress that we're making and how we're building the foundations for long-term value creation. With that, over to you, Harold.
Thank you, Dolf, and a good day to you all. I will take you through the main drivers of our first half financial results and our outlook for the full year 2024. Starting with our top line performance, we posted an organic growth of EUR 900 million, or 6%, reaching EUR 14.8 billion net revenue BEIA . We restored balanced volume and value growth despite experiencing economic volatility in certain markets.
The underlying price mix on a constant geographic basis was up 4.9%, with pricing up 4.5% and all regions in the positive. It was most pronounced in Africa and the Middle East as we priced for inflation and currency devaluations. Overall, our pricing was broadly in line with the weighted average inflation of our markets. The mixed component was positive 0.4% from premiumization. The consolidated volume on an organic basis was up 1.7%, and the growth came mainly from our largest operating companies in Nigeria, Vietnam, India, Mexico, and Brazil. Growth in the second quarter was lower as Easter fell in the first quarter in 2024 compared to the second quarter in 2023. Competition intensified in the economy segment in Brazil, and we suffered from poor June weather in Europe. The translation of foreign currencies had a negative impact on EUR 625 million, or 4.3%, for the first six months.
Close to EUR 600 million of this impact was due to the 48% devaluation of the Nigerian Naira versus the Euro. Using current spot rates applied to the results of last year, the negative effect of translation in the second half will be similar, with lower impact from African currencies and a higher impact from devaluation of the Mexican peso and the Brazilian real. Consolidation changes added EUR 51 million, the net result of the Distell and Namibia Breweries acquisitions, the sale of Vrumona in the Netherlands, and our exit from Russia. Moving on to the next slide, we delivered EUR 2.1 billion operating profit BEIA for the first half year, representing an operating profit margin by a of 14%, up 60 basis points versus the comparable period last year.
The EUR 900 million of net organic net profit net revenue growth on the previous page translated into EUR 242 million operating profit organic growth for the first half. Pricing and strong growth savings delivery from productivity initiatives more than offset in aggregate modest inflationary pressures in our cost base and funded incremental marketing and selling expenses and digitization and sustainability investments. Our variable cost per hectoliter increased organically by low single-digit in line with our guidance as lower commodity and energy costs in the Americas and Europe were more than offset by double-digit increase in Africa and the Middle East, the latter driven by high local inflation and exchange rate devaluations in key markets such as Nigeria and Egypt.
Marketing and sales investments as a percentage of revenue reached 9.9%, similar to last year, yet reflecting an organic increase of EUR 55 million, mainly in the Americas and Africa and the Middle East. We delivered more than EUR 300 million of gross savings across variable and fixed expenses and across regions. We are confident to achieve a EUR 500 million target for 2024. While all regions contributed to the growth in operating profit BEIA , the main contributor was the Americas region, up 36%, 37% in the first half year. Next to top line growth leverage, this was driven by a significant improvement in variable expenses, benefiting from lower commodity costs and favorable transactional currency effects. An important contribution also came from structural productivity savings that delivered outstanding results, especially in Mexico and Brazil. For instance, we made major steps in near-shoring and local sourcing, collaborating with strategic suppliers.
We no longer import 1 billion bottles for Brazil, and we're able to systematically lower our distribution cost and deliver fixed cost productivity. The Africa and the Middle East region achieved the pricing needed to offset the impact from inflation and transactional currency effects, and volume leverage and productivity savings flowed through to operating profit BEIA growth. In Asia Pacific, good performance from India and the top line recovery in Vietnam fueled the operating profit BEIA growth. Europe saw a slight organic increase as lower variable cost and productivity gains were fully reinvested behind growth and competitiveness. Consolidation changes had an impact of EUR 40 million. The transactional currency effect was EUR 62 million negative, mainly from the devaluation of the naira in Nigeria. Now let me cover other key financial data on slide number 17. Most are on a BEIA basis.
I will also bridge between the net profit BEIA and the reported net profit. Started with our share of profits from associate and joint ventures that grew 10.1% by a, led by a strong profit growth of our associate partner in Costa Rica and increased contributions from CCU and CRB. Net interest expenses increased organically by 28.2% to EUR 284 million, in line with our expectations. The increase reflects a higher average net debt position and a higher average effective interest rates, mainly from local borrowings in Nigeria. All the net finance expenses increased to EUR 180 million, mainly due to the non-cash revaluation of foreign currency payables, with the largest impact coming from the devaluation of the Nigerian Naira. To be doubly sure, this is what we flagged in our full year 2023 results announcement.N et profit BEIA a increased 4.4% organically to EUR 1.2 billion.
On a reported basis, we recorded a net loss for the half year, mainly impacted by the non-cash impairment of China Resources Beer as required by IFRS standards and driven by decline in their share price as per the reporting date. The next slide will go into more detail. The effective tax rate BEIA was 28.8%, about 80 basis points higher than last year. Here, the profit mix played a role, as well as the new tax law changes in Brazil. All in all, this resulted in an EPS BEIA increase of 5.9% to EUR 2.15. In line with our dividend policy, interim dividend is set at 40% of the total dividend of the previous year, leading to an interim dividend of EUR 0.69 per share, equal to last year.
Finally, our net debt to EBITDA ratio came down to 2.4x, in line with the company's long-term target of below 2.5x. Let me take a moment to come back to CRB, starting with some business performance indicators. Between 2019 and 2023, CRB's turnover grew by 17% and net profit three times, as reported under the Hong Kong financial reporting standards per calendar year. The strong operational performance was supported by the growth of the premium portfolio led by Heineken, up in volume four times during that four-year period. Also, CRB's contribution to Heineken's result is meaningful, and increasingly so. Royalty income from CRB and CRB's share of profits to Heineken for the first six months of 2024 represented more than 7% of the diluted EPS BEIA, making it a top five contributor to our total net profit.
However, the share price trajectory of CRB has deviated from the strong operational results. At the time of acquisition, the CRB share price was HKD 35, and after a rally lasting until mid-2023, it declined to HKD 26.25 as per the 30th of June 2024, possibly reflecting concerns on the macroeconomic environment in China and its impact on consumer demand. As required by IFRS standards, we have recorded a non-cash impairment of EUR 874 million. This may reverse if the share price rises meaningfully. Let me now turn to free operating cash flow. We recorded the cash inflow for the first six months of the year of EUR 655 million, a EUR 1.1 billion increase from last year. The improvement came for a big part from working capital improvement.
You may recall that last year, our inventory and payables positions were affected by higher safety stocks on scarce materials and impacted by lower volume and other phasing effects. This year, we see those effects normalize. In addition, we are beginning to see results of specific interventions to further improve our working capital positions, for example, by using AI in our forecasting processes and by working with suppliers to bring our payment terms closer to industry standards. CapEx in the first six months was close to EUR 1.2 billion, lower than last year by EUR 212 million and representing 8.8% of net revenue BEIA , in line with our guidance to be below 9%. Cash flow from operations before working capital changes was higher by EUR 94 million, driven by the higher operating profit and a change of EUR 52 million in provisions.
Cash for interest, dividends, and tax increased in aggregate by EUR 60 million, mainly from lower income taxes paid. Let me now turn to the outlook for the rest of the year in the next slide. Our EverGreen strategy is a multi-year journey, and we are pleased with the solid progress in the first half of 2024. While several key emerging markets had to navigate a volatile macroeconomic environment, overall, we believe we achieved a more balanced volume and value-led revenue growth and good operating leverage. We also continue to deliver against our premiumization, digital, and sustainability ambitions funded by growth savings and productivity gains. We continue to expect variable costs to increase organically by a low single digit on a per hectoliter basis. The benefit from lower commodity and energy prices compared to 2023 is more than offset by inflation and currency devaluations in Africa.
We have a clear line of sight on our cost savings initiatives and are therefore confident to achieve our circa EUR 500 million ambition for 2024 ahead of our medium-term commitment of EUR 400 million. We are increasingly reinvesting a larger proportion of these savings into marketing and sales, which we expect will grow significantly and materially ahead in the second half of the year compared to the same period last year. We will do this behind key brands and markets, obviously applying good financial discipline. Volatility remains a reality. Consumer confidence and economic sentiment in developed markets remain below their historic average. The Africa and Middle East region continues to experience challenging conditions. Looking ahead, there is a risk of material currency devaluation that occurred last night, as Dolf just referenced, and also hyperinflation in Nigeria and Egypt.
We are confident that we're able to adapt, yet this continues to bring some short-term uncertainty. We update our full year outlook to grow operating profit organically in the range of 4%-8%. The narrowing of the range reflects our confidence in delivery as we are pleased with the solid performance to date, which is why we remove the lower end of the range. At the same time, we have not seen the best of summers, and main sporting events did not get the uplift that we hoped for. Most importantly, we reiterate our commitment to materially invest behind category and our brand portfolio growth, and this includes a step up in half two versus last year. This is reflected in the adjustment at the upper end of the range. I want to highlight two more elements.
A brief update on the rights issue by Nigerian Breweries. As Dolf has mentioned, we are actively managing the volatility we are facing in Africa to ensure operational resilience and sustainable profitable growth. In Nigeria, a country of close to 230 million people and one of our largest markets in volume terms, the steep devaluation of the Naira, hard currency shortages, and high interest rates led to significant pressure on the balance sheet and the net profit of Nigerian Breweries. The planned recapitalization is on track and will help alleviate these pressures. We aim to use the proceeds of the rights issue of around NGN 600 billion to reduce the company's liabilities. We expect the transition to complete this year, and Heineken will take up its right in full in recapitalization.
You will have noted from our results highlights that the team on the ground is doing an amazing job, giving us confidence in the long-term potential of Nigeria and our ability to build a sustainable future for the business. Second, a comment on the revised outlook for the items between operating profit and net profit. Our effective interest rate is expected to remain unchanged. If current conditions prevail, we expect more stable other net finances expenses in the second half of the year as we made progress in reducing hard currency exposures and are on track with the rights issue in Nigeria, as I just mentioned. And last, we have updated our view on the average effective tax rate BEIA , and now expect this to land at around 28%, an improvement relative to the previous guidance of 29%, including further insights into Brazil's 2024 tax changes.
As a result, we revise the expected organic net profit (BEIA) growth to be more closely in line with the expected operating profit (BEIA) growth. Before the Q&A, to summarize, we had a solid performance in the first half of the year as we restored our balanced volume and value-based growth and delivered operating leverage. We are confident in our cost projections and have clear visibility and increased confidence on our expected growth savings for the year. We will materially increase our marketing and sales investment in the second half of the year, and for this reason, we have revised our guidance to 4%-8% operating profit (BEIA) growth. Over the medium term, we continue to aim to deliver superior balanced growth with operating leverage over time. With that, I would like to open for Q&A.
Lauren, are you ready for Q&A?
Yep. If you'd like to ask a question, then please press star followed by one on your telephone keypad. To withdraw your question, please press star followed by two. Please also ensure that your phone is unmuted locally. As a reminder, please limit yourself to one question and one follow-up, and that is star followed by one to ask a question. Our first question comes from Edward Mundy from Jefferies. Edward, please go ahead.
Afternoon, Dolf, Harold, and Tristan. So my first question is really around the guidance range. You've obviously narrowed it from low to high to 4 to 8 for the year. Could you perhaps talk about what's the bottom end? What are the assumptions around the bottom end of the guidance? What are the assumptions around the top end of the guidance? And then my follow-up question is really around this theme of reinvestment in the second half.
Dolf, you appointed a new Chief Commercial Officer last year, Bram Westenbrink. I think the solid H1 gives you more confidence to invest. Could you perhaps talk about some of the things that you're going to be doing differently since Bram joined the ExCom? Is the focus more on volumes? Is it on price mix? What are you doing differently to help give you that superior top-line growth that Heineken should be able to deliver?
Very good. Thanks, Ed. Let me take the second part of your question, and then Harold can speak to your question on the outlook. Maybe good to start by emphasizing that we are pleased to see the normalization of our top line in the first half. We first had the disruption of COVID, particularly affecting markets with a high dependency on on-premise.
Then we had the disruption more recently by the disproportionate pricing to adapt for input cost inflation that brought volatility to our volumes. And the number one priority this year was to normalize our top line and rebalance it between volume and revenue per hectoliter. And we're pleased at the half-year mark to see that normalization starting to take place with good volume growth 2.1%, 4% plus revenue per hectoliter, positive in all regions. This also really gives us confidence in the future of the category. We really believe beer is a healthy category with sustainable growth prospects for the future, in particular given our more favorite footprint with our exposure to higher growth emerging markets. Back in 2022, we did a very major increase in ATL/BTL. Last year, we had to pause somewhat as we were adjusting to the reality of the moment.
For this year, we really intend to increase and to continue to increase our investment behind our brands and the category. We hold a fundamental belief that the brand power of today is your pricing power for tomorrow. It's important to keep leaning into those investment levels. This will affect primarily the second half of the year as we see the need and opportunity to increase the percentage of revenue of investment levels. It's important that we really aim to be disciplined, that this is really about supporting brand power and pricing power in developed markets. This is really about investing our biggest growth prospects for the future, whether it's India or Brazil, Mexico, South Africa. We're quite specific in where that investment will be deployed. Again, we are happy to see the normalization of our top line with much better balance.
We are confident in continuing to set ourselves up for sustainable balanced growth going forward, and we feel we need to put our money where our mouth is by stepping up in investment. So that's a kind of first kickoff on that question, probably more on that later. Let me hand over to Harold on your question on the outlook.
Yeah. And good day to you, Ed. I think let's start with the bottom end of that range. Important to note that due to the solid results that we've seen in the first half of the year and the fact that we've been able to manage volatility in Africa reasonably well, we decided it was best to remove the bottom end of the range and really move to that 4%. So that is an important point to make.
Secondly, I think in the outlook statement, you will have also seen that uncertainty is still a factor for us to consider. Only last night did Ethiopia devalue its currency, and yes, whilst this is good for the long term, it still may cause a few disruptions for the short term, including, for example, further foreign exchange devaluations that is now very likely to happen, although we don't know what precisely that is. All of these things, including hyperinflation in, for example, Egypt and Nigeria, which we also called out, make us realize that we really want to be quite firm on the investment that we put back onto the business. And as a result of that, we will not sacrifice that investment for the sake of the long-term health of this organization. And that's why these macro factors might actually lead to the bottom end of the range.
Perhaps they will not all happen all at the same time in the back half of this year. At the top end, this is important. We have assumed a normal summer weather, but what has also been clear to us that in June and the early parts of July, this is not a given any longer. So a normalized summer is at the top end of the range. There is an increased step-up of investment happening in the second half of the year, and we believe that this will be good for our business and our growth momentum over time, but not necessarily immediate in the second half of the year.
That was the reason why we wanted to reduce the top end of the previous range also, because we're very confident and determined to keep our investment as we believe is necessary for the category to resume its growth.
Okay, thank you.
T hank you.
Our next question comes from Mitch Collett from Deutsche Bank. Mitch, please go ahead.
Mitch, are you there? I guess we go to the next.
Okay. Yes, we'll move to the next question. Our next question comes from Olivier Nicolai from Goldman Sachs. Olivia, please go ahead.
Hi, good morning, Dolf, Harold, and Tristan. Just a couple of questions on Europe, if I may. You flagged an increase in promotional activity in Europe. Was it mostly linked to the EuroCup, or was it in response to the poor weather in June? And do you see this promotional activity continuing as well into Q3?
And then secondly, on Europe, your margin was flat in H1. Is there any structural reason, thinking more in the long term, why your margin cannot go back to its previous peak margin in Europe, which was reached before COVID? Thank you.
Yes, hi. Thank you, Olivier. Let me start, and then Harold, feel free to complement. Again, we are glad and happy to see after a tough volume result of last year in Europe, we are very happy to see that at the half-year mark, volumes are up, beer volume up +1%. Year-to-date May, we were actually up significantly more. So indeed, June had a disproportionate impact. We were actually counting, as Harold was saying, on some positive upsides in June, July that unfortunately didn't manifest itself. Revenue per hectoliter also still up at the half-year mark +0.7% towards the end of the second quarter.
You saw indeed more promotional pressure, but that was also, we think, related to all the sports activity. Either way, going into summer, that's a normal pattern. Even though we are somewhat disappointed about the start of the summer, assuming normal weather for the remainder of the summer and the rest of the year, we continue to aim for a positive volume effect in the year with modest pricing. Again, it's all about normalizing and rebalancing our outlook, and in the meantime, really making the necessary investments to strengthen brand power, to protect your pricing power, which is something that is especially important in Europe given the retail landscape. Underlying, when you look to the quality of the volume, we're happy to see also in Europe, premium volumes consistently outpacing our mainstream volumes. brand Heineken doing well, Desperados doing well.
So those are the things that we will keep emphasizing in the second half of the year. Let me ask Harold to comment on the margin question.
Maybe just a final thing to say on Europe growth is that about two-thirds of the markets actually gained or held share. I think that is also an important context for us because, of course, last year, there was double-digit pricing, and it did have a knock-on impact on consumer offtake. We believe it's important to bring that balance back, and therefore, are also investing indeed in promotional activity. The investment is actually more important to build the right brand portfolio and support that with marketing and selling expenses. Let's call it the trajectory that we have in front of us.
In terms of the flat operating margin, I tell you that by the end of May, year-to-date, that reality looked very different. The impact of an important summer month like June on country and channel mix because it was Northwest Europe, which was very different. Of course, the on-trade was more affected by poor summer weather than the off-trade. You do know that there is a significant profitability difference between the two. Needless to say, that also our investment in June was relatively high because this is the summer month. As we know, there were major sporting events that we liked to have had a more visible impact on our results. The combination of those two really made that flat operating margin for the first half of the year. It's not what we aspired for. It is definitely what we got.
Underlying, we don't believe that there is a structural issue with our profitability in Europe. We do see that the savings momentum has continued. We also expect that to continue in the second half of the year and with an increase in portfolio mix that Dolf just referenced, more towards premium and mainstream. Important to note that the economy brands and own-label brands are not growing in Europe. We believe that with the right investments, we will get the portfolio to grow and savings to continue. We will see operating margins expand.
Very clear. Thank you.
Thank you. Our next question comes from Sanjeet Aujla from UBS. Sanjeet, please go ahead.
Yeah. Hi, Dolf, Harold, Tristan. Two from me, please. Firstly, can you just talk a little bit about the scale of the marketing increase you're putting through in the second half of the year?
The percentage of revenue marketing spend is still quite a bit below pre-pandemic levels. Is that a level at which you aspire to going into the second half of the year? And my second question is just really on the competitive landscape in a couple of the big emerging markets, Brazil and South Africa in particular. It feels like there's been a bit of a deterioration in the competitive landscape at the low end of the portfolio in Brazil. Love to get your thoughts on that and how that's progressing. And also in South Africa, it's been a year since the Distell acquisition. Love to get your assessment on how, particularly in the beer portfolio, things are progressing versus expectations. Thank you.
Very good. Thanks, Sanjeet. Let me answer the competitiveness question, and maybe you can take the marketing investment, Harold.
On the competitive situation, when we look to Brazil, we see continued momentum in premium, which is of the utmost importance to our portfolio, of course, as we are highly skewed that way. We continue to see double-digit increases both in the first quarter and the second quarter in our premium portfolio with brand Heineken. That is incredibly important, and yeah, we're proud to be able to deliver that. The mainstream segment has been impacted by the price war in the economy brands initiated by a local competitor. We are quite balanced in that we don't want to engage in that segment of the market. And as such, we have accepted double-digit volume increase in our economy brand volume. Important is that Brand Amstel continues to grow up around low teens at the half-year mark. Amstel and Heineken and some of the secondary premium brands are our priority.
Across the first half, we have realized a very significant increase in our profitability. So we're actually, yes, we are aware that there's stuff happening in the low end in the economy, but we are very determined on our strategy, focusing on mainstream and premium with Amstel and Heineken as the lead brands. We really believe that continues also at the half-year mark to deliver results that we require. South Africa, indeed, more challenging. We are now at the one-year milestone of the acquisition. A very complex, almost, yeah, in fact, a backwards integration. The former Distell categories are actually performing very well. Very solid growth coming from the cider and S&B portfolio with brands like Savanna and Bernini growing in the double-digit. Continued positive momentum on the wine portfolio, growing volume and share, also share gains in the spirit portfolio.
In beer, we know there's more to do. It's good to see momentum starting slowly but surely to come back on brand Heineken. We have launched in the second quarter the returnable bottle, which is something we were never able to do standalone. Now, glad that we're starting to roll that out. We'll take a couple more months to fully stabilize, but that will have a major effect on gross margins going forward. So pleased with the progress on integration, pleased with the share performance on the Distell categories, not yet pleased on the momentum of our beer portfolio. That is the top priority for the team on the ground. Maybe one other reason, addition to the portfolio, India, a very important market for us right now and going forward, seeing high single digits in the first half. Kingfisher, the absolute market leader with very positive momentum.
Our premium brands growing in the 30%. So we're really happy to see with our momentum in that market. So you see balance across the footprint. In some places, more work to do than in others, but in the aggregate, we are quite happy and quite clear on the things that we should address. Thanks, Sanjeet. Over to Harold.
Yeah. So on the point on the marketing percentage in the second half of the year, I think if we compare that, the reality of the second half of last year versus what our expectation is now to this year, it is very different. So last year, we were actually operating in an environment where high pricing led to actually a decline in volumes, and we had to course-correct our investment because it was clear that the consumer was more worried about pricing and inflation than it was about brand power.
In the first half of the year, we're growing volumes, and we're actually seeing a level of normalization happening in markets. Brazil is in growth. Mexico beer market is in growth. Vietnam is stabilizing. Europe is stabilizing. And this is there for the moment to also consciously and materially step up our investments to really drive that category growth back as well as invest behind the power of our brands. We're also extremely pleased that premiumization and, where relevant, also upper mainstream continues to be the segments of the market because those are the segments that we have a disproportionate strength in. And therefore, that material step-up will actually fuel that growth, hopefully, as well. So what we're really ambitioning is that after a period of volatility, we bring stability in our investments for consistent, yeah, quarter-on-quarter volume and also value growth.
So indeed, the return in the second half of the year of marketing expenses will not go fully back to 11%. I think that will be too big of a step in one go. And as Dolf said, we want to do this with discipline and with the right intent behind it, but you will see a material and significant step-up.
Thank you, Harold.
Can I just squeeze in a quick follow-up on the other net finance cost outlook? I think you said stable. Do you mean stable versus the first half or versus the second half of last year?
Yeah. So I got myself a little bit in a twist when I tried to explain all the detail in the full year results.
So what we actually mean to say is that the net profit, because of these three factors, interest, tax, and all the net financing expenses, that the net profit growth is now closer to the operating profit growth. And therefore, what I meant with the word stable is that we've got less volatility to manage now because the refinancing in Nigeria is firmly on track. Frankly, what currencies do and how much it's for me impossible to predict, I think we will be pleased that there is just less volatility out there now than what we had in the first half of the year. But let me leave it at that. And if you can just zoom in on the net profit growth versus operating profit growth, I think you got it right.
Thank you.
Thank you. Our next question comes from Mitch Collett from Deutsche Bank. Mitch, please go ahead.
Hi, Dolf. Hi, Harold. Apologies for my sound issues earlier. I think I've understood that you increased your marketing spend in Europe based on your question response earlier, but it was broadly flat as a percentage of sales overall. So did you reduce it in one of the regions? And if so, can you help us understand where? And then for my follow-up, you mentioned that Vietnam was a drag on Asia-Pacific margins in the first half, but clearly you had very strong revenue recovery, which I would have thought would have given you some margin expansion for Vietnam. I appreciate it's a more challenging market than it was in the past, but can you talk through the drivers of that margin pressure? And do you think there's scope to recover some of what was lost in Asia-Pacific via Vietnam? Thank you.
Yeah. Let me start by responding on Vietnam, and then we take it from there. So good to spend a bit of time on Vietnam given it's such an important market. One, we are happy to see that after the high single-digit market decline in the second half of last year, we see signs that the market is stabilizing. We are estimating that the market was down by low single digits in the first half of the year. The on-trade channel and with that, the premium segment is really trailing that still, and that's affecting our portfolio. In the first half, we really benefited from cycling the destocking effect in the first half of last year. And that's why we were at a high single-digit volume growth in the first half.
That will not persist because that favorability of the cycling, the destocking will disappear in the second half of the year. And then we will be really more exposed to the underlying dynamic of the market where, again, we still have some unfavorability on the mix. We are making a huge effort in balancing our portfolio. Historically, we have been over-reliant on premium. We know one of the top priorities is to continue to boost our mainstream portfolio, which we have been doing for the last four or five years, but still, we are below fair share in that segment. With that, we are happy to see the double-digit volume increases in Bia Viet and in Bivina. In Larue, there's more work to do, but we're really encouraged by the momentum of the new innovation, Larue Smooth .
In premium, we still have work to do on Tiger Original, but we're happy to see with continued double-digit increases on Tiger Crystal, as well as on brand Heineken, up over 60% in the year to date. So a lot happening on the portfolio and on rebalancing that portfolio from over-reliance on premium, over-reliance on Tiger to a more diversified portfolio. And as I think we have discussed on this call at the full year result, the historic margins won't come back. We are operating in 40+ territory. We don't see that come back, but we do believe that in the high 20s, around 30% margin, we should be able to operate going forward. Right now, we are also really making sure that we are having the right marketing and selling expenses in Vietnam as we're rebuilding our momentum, as we're adapting to the new reality of rebuilding momentum.
Now, what's important to note on the APAC results is that the high single-digit growth in India at this point still comes with significant lower margins. So there's also a big mix effect at the regional level. So in a way, the lower margin in Vietnam was already in our full year results of last year. And now that margin will continue to operate in that high 20s. The margin effect with India outgrowing the rest of the region will continue. And we just want to make sure that in the absolutes, it really makes sense because we really believe in the long-term prospect of India. It's similar to what we have done in Brazil, where for a very long time, we were operating at very low margins, but we were building the portfolio and the route-to-market strength to capture the value in the market.
And we see that coming through now at pace and at scale in the Brazilian market. That's what we are setting ourselves up for in India, but knowing that, like Brazil, that will take some years to fully materialize. So that's it for me. Harold, anything to add to that?
Yeah. Let me be brief on the marketing and selling. Where did it go up and where did it go down? A bit like that mix of markets that Dolf was just talking about is also the case in APAC because India has now grown quite materially, but also operates with lower marketing and selling expenses in that line than, for example, Vietnam has. Secondly. Yeah. Secondly, we had some other of the APAC markets that really invested ahead of the curve in the first half of 2023, and that has now much more normalized.
I think Indonesia, Vietnam, sorry, Indonesia, Cambodia, for example. So these were small adjustments. I wouldn't want you to read too much into that. The main increase in the investment was really done in the Americas and certain of the African markets.
Thank you both.
Thanks, Mitch.
Thank you. Our next question comes from Andrea Pistacchi from Bank of America. Andrea, please go ahead.
Yes. Thank you. So two questions, please. First one is on the balance sheet, which is deleveraging quite fast, approaching probably 2 times net debt/EBITDA by the end of the year. Maybe not quite there, but approaching. At the same time, the stock is trading on a rather low P/E compared to history. So how are you thinking about potential cash returns? Is there a level of the balance sheet that would make you comfortable to buy back?
The second question really is actually just a clarification, again, I'm sorry, on marketing, on the reinvestment. You're saying, I mean, very clearly that you want to step up marketing reinvestment in the second half. Is the reinvestment you're planning for H2 higher than what you were planning six months ago at the beginning of this year? And if so, what has driven this change? And is the reason is this potentially the reason why you're capping the upper end of the guidance at 8% organic EBIT rather than high single digit? Thank you.
Yeah. So yes, we're pleased with our cash flow performance and the fact that we are deleveraging. As you know, because we've repeatedly spoke about that, is that this offers opportunities for us, but the opportunities also have a priority order.
We first and foremost always want to invest in the organic part of our business. Dividend policy, we are very happy with and make sure that that is intact. We also believe that the net debt to EBITDA ratio needs to be maintained. We want to expand into organic growth. For example, we're putting more CapEx and new breweries in. And at the moment, also important to invest behind sustainability and digital initiatives. That comes with a higher CapEx line. And only when we run out of other options will we, of course, first and foremost, look at inorganic opportunities to bolster our footprint. And only thereafter are we going to consider things like buyback. And that's also the priority order that we gave when we did the FEMSA transaction. I don't think that our strategy in that has changed at all.
So we will see, but we are, yeah, we're keeping an eye open on what the opportunities are. Perhaps for the marketing step-up, I'll hand over to Dolf.
Yeah. Let me start by zooming out before I zoom in. We started the year with a broad outlook, low single digit to high single digit. Also, having learned from the inflation that hit us last year, we really wanted to make sure that we were, yeah, conservative in our outlook. At the half-year mark, on one side, we are more confident because we see more we have more visibility with a very strong and solid delivery in the first half. Navigating the volatility in Africa is going according to plan, and we start seeing there less downside than we otherwise would have thought at the beginning of the year. And it gives us the confidence to remove that lower mark.
That's an expression of both visibility and increased confidence. The step-up in marketing in the second half was always in our plans. That is not new. And again, it has a lot to do that at the beginning of the first half of last year, we were investing in full, and we had to pull that back in the second half of last year as we were confronted by a material deceleration in our volume. In the first half of this year, we have been investing in full, both as a percentage of revenue with a EUR 50-60 million increase in absolute. And we want to normalize that in the second half. And just doing the math, that is leading to a very material increase in absolute spend. And again, we are very disciplined and clear where that needs to go. This was always in our plan.
The reason why we're somewhat narrowing our range at the top end is that some of the upside that we had hoped for in Europe, we have not seen materializing. I don't want to reiterate that. And we want to, in the end, we want to strike the right balance between delivering decent solid results in this year and setting ourselves up for strong results in the year to come. And we don't want to find ourselves in a situation where going into the fourth quarter, we have to cut marketing and selling because we are starting to get squeezed on the outlook that we have given.
And as such, the priority is really that balance, good solid results in that 4-8 range, and at the same time, doing the investment, normalizing our investment levels, balancing between the first half and the second half, correcting for what happened last year so that we set ourselves up for good results next year and beyond.
Lauren, do you have a final question? Sorry.
Thank you. Thanks, Andrea. Final question, I believe.
Yes. Our final question comes from Trevor Stirling from Bernstein. Trevor, please go ahead.
Hi, Dolf, Harold, and Tristan. Returning to A&P, Dolf, but a slightly different angle. How do you measure the impact of A&P? And I think Harold said it was unlikely to be coming through the impact that was likely to come through in the second half.
But is this a mixture of shorter-term promotion that you would expect to show up towards the end of the half and long-term brand equity? What sort of mix of investments do you have going in as well?
Yes. Thanks, Trevor. Of course, that's the $1 million question. What is interesting that in the time and era that we are living, we start having much more sophisticated marketing mix models where we start scenario playing our investments and the return on investment in ways that were not possible in the past. It's still not complete exact science. It's always a mix between more long-term ATL, driving your brand power, driving awareness levels, driving differentiation, to more bringing experiences, activating our brands close to the point of consumption, all the way to more promotional activities like activities around specific occasions as the Euro Cup or otherwise.
The real kind of sales promotion or, let's say, anything that directly drives volume sits more in our net revenue line, give or take. But of course, in that marketing and selling bucket, it is a range between more long-term ATL to more short-term BTL. And again, with the marketing mix models that we are continuing to build, that we're continuing to expand, where AI is starting to become a more and more relevant lever, we do believe that this significant step-up, which still would leave us short of the historic 11%. So it's a big absolute step-up, but we're still kind of heading in the direction where we have been in the past. We believe that we can spend this money in both an effective and disciplined way, well-targeted against the biggest opportunities.
Thank you very much, Dolf.
Fantastic. I think with that, we come to an end.
Thanks, everybody, for dialing in today. I don't know about you, but the sun is shining in Amsterdam. We take it, and hopefully, it's the beginning of a nice long, warm period in Europe. For all of you here, wishing you a happy summer break and see you soon. Take care. Bye.
