A sugary drink tax could reshape China's functional beverage landscape, benefiting Nongfu and pressuring Eastroc

Overview

The report focuses on the investment implications for China's functional beverage and soft drink sectors under sugar-control policies. Bernstein believes that the rising burden of chronic disease, obesity, diabetes, and cardiovascular disease in China makes the central government more likely to adopt more direct policy tools such as a sugary drink tax. If a 20% sugary drink tax is introduced in early 2027, consumption will shift from high-sugar energy drinks and sweet ready-to-drink tea toward sugar-free ready-to-drink tea, packaged water, and low-sugar substitutes, creating a positive catalyst for Nongfu Spring and a negative shock for Eastroc Beverage.

Core views

The core views are: first, the probability is rising that sugar-control policy will move from education and labeling to taxation; second, sugary drinks are highly price-elastic, and a 20% tax rate could lead to a 20%-32% drop in consumption; third, Nongfu Spring's zero-sugar products such as Oriental Leaf and packaged water are better positioned to capture substitution demand; fourth, Eastroc Beverage's core energy drinks have high sugar content and concentrated profit contribution, so a sugar tax would amplify pressure from slower category growth, product substitution, and margin dilution.

Analysis framework

The report uses policy scenario analysis, the WHO price elasticity framework, category demand models, and company segment profit estimates to map the assumed 20% sugary drink tax to changes in volume, revenue, EBIT, and EPS for sugar-free ready-to-drink tea, energy drinks, packaged water, and electrolyte drinks, and cross-validates target prices through NTM P/E and DCF.

Methodology notes

• Policy scenario analysis20% sugary drink tax scenario

  Assumes China introduces a sugary drink tax in early 2027, raising consumer prices by 20%.

  This scenario is used to assess sugary drink consumption substitution, changes in category growth, and the sensitivity of Nongfu Spring's and Eastroc Beverage's revenue, EBIT, and EPS.

• Demand elasticity analysisSugary drink price elasticity

  Uses price elasticity of about -1.0x to -1.6x to estimate the impact of taxation on consumption.

  Under the assumption of a 20% price increase, the report estimates that sugary drink consumption could decline by 20%-32%, while pushing consumers toward sugar-free tea, water, and low-sugar substitutes.

• Company segment modelCategory revenue and profit bridge

  Maps changes in beverage category growth to company segment revenue, EBIT, and group EPS.

  Nongfu's water and ready-to-drink tea account for the bulk of FY25 revenue and EBIT and benefit more clearly under the sugar-tax scenario; Eastroc's energy drinks account for a high share of revenue and profit, making the tax impact more concentrated.

• Valuation methodsNTM P/E and DCF cross-validation

  Uses target NTM P/E multiples with reference to DCF-implied valuation.

  Nongfu Spring's target price of HK$53 is based on 22.0x NTM P/E; Eastroc's A-share target price of RMB142 is based on 15.7x NTM P/E, and its H-share target price of HK$138 is based on 13.3x NTM P/E with consideration of the A-H premium.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Nongfu Spring Co Ltd（9633.HK）

  Primary beneficiary

  Strengths

  High contribution from zero-sugar products such as Oriental Leaf and packaged water; in FY25, water and ready-to-drink tea together account for 77% of revenue and 78% of EBIT, with strong revenue and profit elasticity under the sugar-tax scenario.

  Weaknesses

  Some products, such as Tea Pi and Scream, still contain moderate sugar levels and may require formula adjustments; if the healthy beverage trend slows, growth in sugar-free tea may come in below expectations.

  Comparison

  Compared with Eastroc, Nongfu's product mix is more tilted toward low-sugar and sugar-free offerings, allowing it to better capture consumer substitution demand.

  Risks

  Raw material price shocks, weakening macro conditions and consumer spending in China, reversal of the health trend, or slower-than-expected growth in sugar-free ready-to-drink tea.

• Eastroc Beverage Group Co Ltd（605499.CH；9980.HK）

  Primary pressured name

  Strengths

  Nationwide channel expansion, improved distributor efficiency, and continued expansion in electrolyte drinks and other beverages can still provide sources of growth.

  Weaknesses

  Core energy drinks account for 75% of revenue and 85% of profit, with high sugar content; zero-sugar energy drinks may cannibalize existing products, while non-energy categories have lower profit margins.

  Comparison

  Compared with Nongfu, Eastroc is more dependent on high-sugar energy drinks, so the negative elasticity of a sugar tax on demand and profit is greater.

  Risks

  If a sugar tax is implemented, it may suppress demand through higher consumer prices, or margins may be squeezed if the company absorbs the tax burden; however, if non-energy categories achieve scale economies faster, part of the negative impact could be offset.

• Sugar-free ready-to-drink tea category

  Beneficiary category direction

  Strengths

  Aligned with sugar control, low-calorie, and healthy consumption trends; under the sugar-tax scenario, it is well positioned to capture demand shifting from sweet tea and carbonated drinks.

  Weaknesses

  High growth may attract more competitors, intensifying share and price competition.

  Comparison

  Compared with high-sugar energy drinks and sweet ready-to-drink tea, sugar-free ready-to-drink tea enjoys a more favorable backdrop in both policy and consumer trends.

  Risks

  Changes in consumer taste, intensifying competition, or inadequate channel execution could weaken growth delivery.

• High-sugar energy drink category

  Pressured category direction

  Strengths

  Functional demand and channel penetration still provide support, and zero-sugar variants can partly cushion the policy impact.

  Weaknesses

  High sugar content and clear tax pass-through make it vulnerable to price increases and shifts in health awareness.

  Comparison

  Compared with sugar-free tea and water, energy drinks are more likely to face volume and margin pressure under the sugar-tax scenario.

  Risks

  If the tax is delayed or the rate is lower than expected, the near-term shock would be reduced; if zero-sugar products scale successfully, the category downturn may be milder than the report scenario suggests.

Key data

• Policy targetBy 2030, average daily sugar intake per capita reduced to 25g; premature mortality among people aged 30-70 reduced to below 13%Healthy China-related targets form the basis for the report's view that pressure for a sugar tax policy is rising.
• Tax rate assumption20%The report uses the minimum effective sugary drink tax rate recommended by WHO as its core scenario.
• Sugary drink price elasticityAbout -1.0x to -1.6xThis implies that a 20% price increase could lead to a 20%-32% decline in consumption.
• Average sugar content of China's non-water soft drinksPeak 9.9g/100ml; 2025E at 9.2g; 2030E base case at 8.3g, sugar-tax scenario at 7.7gThe report believes that even without a sugar tax, sugar content in soft drinks is declining, and taxation would accelerate the trend.
• Sugar-free ready-to-drink tea under sugar-tax scenarioConsumption growth could accelerate to about 41%The report believes sugar-free ready-to-drink tea is the most direct category beneficiary of the sugar-control trend and a sugar tax.
• Energy drinks under sugar-tax scenarioConsumption growth could slow to 1.6%High-sugar energy drinks are affected by both the tax burden and substitution by zero-sugar alternatives.
• Nongfu Spring financial impactRevenue CAGR rises from 14% to 16%; EPS CAGR rises from 17.8% to 22.7%Mainly benefits from accelerated demand for sugar-free ready-to-drink tea and packaged water.
• Eastroc Beverage financial impactNet profit CAGR falls from +16.8% to -5.6%; group EBIT CAGR falls from 18% to 1%High exposure to core energy drinks, while non-energy categories have lower profit margins.
• Sugar content of Eastroc's core product12.3g/100mlThe report states this is 16% higher than Coca-Cola and about 30% higher than major sweet ready-to-drink tea brands.
• Relative impact versus consensusUnder the sugar-tax scenario, Nongfu 2027E EPS is 18% above consensus; Eastroc 2027E EPS is 32% below consensusReflects the directional divergence in policy-scenario impact on market expectations.

Impact & implications

The investment implication is that if sugar-control policy shifts from soft constraints to taxation, it will accelerate the migration of China's beverage mix from high-sugar to low-sugar and sugar-free products. With Oriental Leaf, packaged water, and a healthy beverage portfolio, Nongfu Spring is likely to gain catalysts in revenue growth, margin, and valuation; Eastroc Beverage, by contrast, may face slowing demand, self-cannibalization from new zero-sugar products, competitive share loss, and margin dilution because of the high sugar content and profit contribution of its core energy drinks.

Risks

• The timing, tax base, collection method, and actual tax rate of a sugary drink tax remain uncertain; if the policy is delayed or weaker than expected, the scenario impact will be lower than estimated.
• Consumer acceptance of sugar-free and low-sugar substitutes may be weaker than expected, or taste retention after reformulation may be poor.
• Nongfu Spring faces risks from a slowdown in healthy consumption trends, raw material price shocks, and weaker macro consumption in China.
• If Eastroc Beverage's non-energy drinks reach scale economies faster and distributor efficiency improves more than expected, the negative margin impact may be partly offset.
• Competitors may accelerate the launch of zero-sugar and low-sugar products, intensifying share competition in beneficiary categories such as sugar-free tea and zero-sugar energy drinks.

What to watch

• Policy developments from China's central government on sugary drink tax, front-of-pack labeling, restrictions on high-sugar drinks on campuses, and mandatory sugar-content labeling.
• Whether a clear tax rate, collection scope, implementation regions, and rollout timetable emerge around 2027.
• Changes in volume, pricing, and margins for Nongfu Oriental Leaf, packaged water, and other low-sugar products.
• Scale-up of Eastroc Zero Sugar Energy, E-Water, and electrolyte drinks, along with reformulation results, channel feedback, and gross margin trends.
• The speed of consumption substitution among sugar-free ready-to-drink tea, sweet ready-to-drink tea, carbonated drinks, and energy drinks.
• Whether public health data on chronic disease, obesity, diabetes, and cardiovascular disease continue to reinforce policy pressure.
