Relative Relative to MSCI Emerging Markets Index (USD) - second quarter 2021 contribution (%)

Prosus Nv (Eq) Holdings of e-commerce, social and corporate platforms provider Prosus (Netherlands) hindered relative returns. The company's -0.7 share price declined, following an ownership change proposal. Prosus announced that it is launching a share exchange offer to Naspers shareholders, in an attempt to reduce Naspers' holding of Prosus to 57% and increase Prosus' free float to approximately 60%. The deal presented several potential governance, tax and related-party risks for some of its shareholders. Gree Elec Applican Holdings of air conditioner manufacturer Appliances (China) weighed on relative performance. The company -0.5 reported net profit results that were lower than expected as air conditioners, lifestyle appliances and smart equipment revenue declined.

New Oriental Edu & An overweight position in private educational services provider New Oriental Education & Technology Group (China) detracted -0.3 from relative performance. Although the company reported strong first-quarter revenue results, its stock price declined following Tech Group Inc concerns that the Chinese government was looking to introduce policies to regulate private tutoring companies.

AmBev SA An overweight position in beverage manufacturer AmBev (Brazil) aided relative results. The stock price rose as the company 0.3 reported higher-than-expected adjusted earnings, driven by increased revenue in Brazil Beer, and greater-than-expected margins, primarily due to a substantial mix improvement, as Ambev continued to report substantial growth of its premium portfolio. Sberbank The portfolio's overweight position in commercial banking firm Sberbank (Russia) helped relative returns, driven by 0.2 better-than-expected net profits, which were supported by lower provisions and lower operating costs. Naspers Ltd (Eq) Not owning shares of multinational media company Naspers (South Africa) aided relative returns. Although the company reported 0.2 solid financial results for the quarter, driven by revenue growth in its food delivery and online classified segments, its stock price declined, despite the lack of any significant negative news.

2Q21 MARKET REVIEW AND OUTLOOK

Emerging markets finished the second quarter in positive territory, making it five straight quarters of positive returns since the market collapsed in the first quarter of last year. Style wise, value continued its outperformance that began in the fourth quarter of 2020, as commodity-related sectors such as energy, materials and industrials did well on the back of higher commodity prices. Meanwhile, mid- and small-cap companies outperformed their large- cap peers, as investor sentiment on the large-cap Chinese internet companies remains suppressed by regulatory concerns.

Stock selection within consumer discretionary was the major detractor this quarter. In particular, our holdings in Prosus and New Oriental Education & Technology Group hurt. Prosus is a holding company. The vast majority of Prosus' NAV is made up of its 30% stake in China's Tencent. Sentiment on Tencent and more broadly Chinese internet companies has been weak over the past few quarters due to numerous manifestations of heightened regulatory risks, such as the anti-monopoly law.

In our opinion, so far, these antitrust regulations mostly look like good regulation and are applied evenly across companies. Since the antitrust regulations were promulgated, various companies have been fined notional amounts for not submitting previous M&A deals for appropriate regulatory screening or for improper anti-competitive pricing. The regulator appears to be mostly focused on compliance with fair trading rules and enforcing the M&A approval process. Regardless, regulatory concerns will likely continue to weigh on internet companies in the near term.

Longer term, we remain positive on the business fundamentals for Tencent. Its Wechat app is the most popular app in China and therefore has strong network effects. It is a deeply moated monopoly that earns high margins. Furthermore, we believe the Wechat app is undermonetized relative to time spent on the app, which offers scope for significant revenue growth going forward. In our opinion, the Wechat app's dominance also allows Tencent to leverage itself into adjacent duopolies such as game publishing, payments and cloud.

The share price of New Oriental Education & Technology, which provides private education services, has been under pressure as investors are increasingly concerned about tighter regulations for the broader industry. Notably, there has not been an official policy announcement. We witnessed a similar episode of tighter regulations for the industry back in 2018, and the industry eventually emerged stronger. In our opinion, the Chinese government’s objective is ultimately to alleviate concerns around the quantity and quality of education services, and not to ‘kill’ profits for the industry. In fact, we believe that tighter regulations could potentially be more beneficial to larger players such as New Oriental, as the cost of compliance will be exponentially higher for the smaller players.

15 FOR DEALER AND INSTITUTIONAL USE ONLY. - MFS Emerging Markets Equity Fund 45695.6 15 PRPEQ-FEM-30-Jun-21 Portfolio Outlook and Positioning

Also, our underweight to Chinese auto manufacturers, particularly electric vehicle manufacturers, hurt. Within the autos industry, we prefer Indian auto manufacturers such as Mahindra & Mahindra and Hero Motocorp. India is one of the handful of auto markets globally where there is still growth, as very few people own cars as compared to other countries globally. We believe there is still a long runway for growth for these Indian auto manufacturers.

Earnings growth in the region has been broadly positive year to date, partly due to the low base effect from last year. However, earnings growth is still somewhat concentrated within companies in the technology and materials sectors. This can be directly attributed to the strong demand for semiconductors, which in turn is powered by increasing demand for higher computing power globally across a variety of applications. Ideally, for the market rally to be sustainable, we would like to see earnings growth broaden out to other sectors like financials and consumer services.

The limited supply of COVID-19 vaccines has so far prevented a stronger economic recovery within emerging markets. Therefore, it is reasonable to assume that as vaccination programs ramp up, it will allow an easing of COVID-19 related mobility restrictions and open the way to a more broad-based recovery across emerging markets. In our opinion, this appears to be the base case that is currently priced in by the market, as emerging markets are now trading above pre-COVID levels, up more than 60% from the end of the first quarter of 2020.

This gives us reason to be more cautious as the rise of COVID-19 variants could potentially throw a spanner in the works. Additionally, political uncertainty as most Latin American countries head into elections season is another risk that we are mindful of. As we have seen in recent elections globally, it is very difficult to forecast with any accuracy what will happen. Our focus remains firmly on companies that are cash flow generative and have a healthy balance sheet.

PORTFOLIO POSITIONING

The portfolio is overweight to consumer staples and discretionary companies and high-quality, long-term holdings within financials such as AIA, HDFC and Sberbank. This is offset by our underweight to health care, as well as the more cyclical sectors such as materials and energy. Over the course of the quarter, we mostly made adjustments at the margins, trimming relative winners and topping up relative underperformers where we have conviction in the investment thesis.

Key trades for the quarter include:

We started a new position in Taiwan’s Hon Hai Precision Industry, a global leader in electronics contract manufacturing. Hon Hai’s long-term strategic goal is to be involved in three emerging areas of manufacturing — growth, electric vehicles (EVs), robotic and digital healthcare — all of which will be 16 FOR DEALER AND INSTITUTIONAL USE ONLY. - MFS Emerging Markets Equity Fund 45695.6 16 PRPEQ-FEM-30-Jun-21 Portfolio Outlook and Positioning

developed by leveraging their expertise in manufacturing at scale for hardware verticals. Hon Hai has been working on its own EV ecosystem for the past four years and has collaborated with a large list of partners. In particular, the arrangement to make EVs for Geely, a company that currently makes some 1.2M cars annually, is the most promising one from a long-term perspective. In our opinion, there is significant growth potential for Hon Hai, if it can successfully execute on its strategy to transform into a serious player within the EV manufacturing value chain. Meanwhile, Hon Hai’s core electronics assembly business is humming along smoothly. Management appears confident on further improving efficiencies and has guided for a 70% improvement in margins on the assembly business. We funded this by trimming relative outperformers such as Taiwan Semiconductor, Samsung Electronics and Vtech holdings.

We continued to build our position in B3, the Brazilian stock exchange. We have a positive view on the exchange business as they are typically near monopoly businesses that have diversified away from trading volume-linked revenue in the past to more recurring, less volatile revenue streams such as providing information services today. The business has generated strong returns and has had strong free cash flow conversion. The Brazilian equity market is still relatively underdeveloped, but penetration is rising so we believe there is a long runway for growth for the exchange business in this market.

We topped up our holdings in Alrosa early in the quarter. Alrosa is a Russian diamond mining company and is the world's largest diamond miner by volume. We believe that demand for diamonds will continue to be strong as economies reopen. This is consistent with what we have seen with other luxury goods companies. At the same time, Alrosa’s diamond inventory levels are at a multi-year low and this gives the company the opportunity to increase its prices to meet demand. Alrosa is working to improve its product mix by selling higher quality diamonds, which in turn should result in higher earnings and margins in the medium term. Towards the end of the quarter, its share price moved up very strongly within a short period of time and so we decided to take a small trim and lock in some profits.

The portfolio has consistently maintained a bias towards high-quality, above-average-growth companies. We rely on our global research platform to identify companies that meet our five key criteria: free cash flow generation, high return on invested capital, low leverage, strong corporate governance and reasonable valuation.
