Factors Affecting Performance [Text Block]
HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes Airlines ETF (AIRL) launched December 8, 2023 and has seen a 6.63% return since inception. AIRL seeks to track the Solactive Airlines Index (SOLAIRN), which identifies the largest 30 airline companies by market capitalization. AIRL seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the SOLAIRN Index.
Airline stocks have had a mixed performance in 2024, with some volatility influenced by multiple factors, including fluctuating fuel prices, economic uncertainty, and political unrest. Although fuel costs per gallon in the U.S. dipped slightly from July 2024 to August 2024, reaching $2.47, they remain significantly higher than pre-pandemic levels. Fuel costs and price volatility are crucial as they can impact operational costs, especially for budget carriers heavily reliant on cost control. The industry also faces global challenges, including inflation, supply chain issues, and sporadic disruptions from political instability in certain regions. However, a strong travel demand has largely offset these factors, especially with Asia-Pacific markets recovering and airlines forecasting higher passenger revenue growth. This demand has boosted industry performance. Despite this recovery, the industry still trades below pre-pandemic levels.
The top contributor and detractor AIRL’s performance included Skywest, which increased by 73.47%, and Spirit Airlines, which declined 82.91%.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes Cloud Computing ETF (CLOD) launched on December 15, 2023 and has seen a 12.21% return since inception. CLOD seeks to track the Solactive Cloud Computing Index (SOLCLOUN), which identifies the largest 50 companies by market capitalization that derive their revenues from: (1) Digital Security, (2) E-Commerce, (3) Infrastructure, (4) Data Infrastructure, (5) Data Architecture, (6) Internet Infrastructure, and (7) Data Support. CLOD seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the SOLCLOUN Index.
Cloud computing stock have seen solid growth in 2024, largely fueled by increasing corporate investments in digital infrastructure and AI-driven solutions, as organizations scale up remote work solutions and data storage needs. However, this sector has faced some challenges due to rising costs associated with expanding cloud infrastructure and operational expenses. These expenses are compounded by global supply chain issues that have affected the availability of necessary components for data centers and cloud servers. Political factors, such as regulations on data privacy and security, have also impacted the industry. Despite these obstacles, strong demand for cloud services across sectors like e-commerce, entertainment, and artificial intelligence applications has sustained positive performance, reinforcing cloud computing as a critical component of business modernization strategies.
The top contributor and detractor to CLOD’s performance included Oracle Corp, which increased by 66.56%, and Snowflake Inc – Class A, which declined 42.28%.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes Copper Miners ETF (COPA) launched September 24, 2024 and has seen a 12.03% return since inception. COPA seeks to track the BITA Global Copper Mining Select Index (BGCMSI), which identifies companies that derive their revenues from copper mining, explorations, refining, and royalties. COPA seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the BGCMSI Index.
Copper mining stocks have seen strong performance this year, largely driven by a surge in demand linked to the global transition to clean energy technologies. The critical role of copper in electric vehicles, solar panels, and wind energy systems has led to increased demand for copper. As of September 2024, copper prices are hovering around $4.31 per pound, which reflects a recovery from earlier lows this year, boosting investor sentiment and leading to increased interest in copper-related investments.
The top contributor and detractor to COPA’s performance included Jiujiang Defu Technologies Class - A, which increased by 29.81%, and Ero Copper Corp, which declined 1.20%.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes European Luxury ETF (FINE) launched December 15, 2023 and has seen a -5.02% return since inception. FINE seeks to track the Solactive European Luxury Index (SOLELUXN), which identifies 25 European luxury companies that generate their revenues from either: (1) Luxury Accessories, (2) Premium Clothing, (3) Luxury Beauty Products, (4) Cars & Yachts or (5) Upscale Hospitality. FINE seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the SOLELUXN Index.
Luxury stocks have seen notable volatility this year, as demand for high-end goods has been heavily influenced by economic conditions in China, a critical market for luxury brands. As one of the world’s largest consumer bases for luxury products, China’s economic fluctuations directly impact the performance of luxury-focused stocks. With China experiencing slower-than-expected economic recovery and consumer spending tightening, luxury companies that rely on affluent Chinese shoppers have faced softer sales growth. However, despite these headwinds, the global demand for luxury goods remains resilient, especially in the U.S. and Europe, helping to balance some of the downturn in Asia.
The top contributor and detractor to FINE’s performance included COATS Group PLC, which increased by 41.85%, and Burberry Group PLC, which declined 49.10%.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes Global Systemically Important Banks ETF (GSIB) launched December 15, 2023 and has seen a 25.09% return since inception. GSIB actively invests in the 28 publicly traded global banks that have been identified as “systemically important” by the Financial Stability Board (FSB) and the Basel Committee on Banking Supervision (BCBS). A bank is deemed “systemically important” due to its size, interconnectedness, financial infrastructure, complexity, and cross juris dictional activity.
Global Systemically Important Banks stocks have performed well this year, supported by rising net interest income (NII) due to higher interest rates, which allow banks to earn more from the spread between what they pay on deposits and what they earn on loans. Additionally, there has been a gradual recovery in investment banking activities, with increased mergers and acquisitions, IPOs, and other capital markets transactions boosting fee income. This rebound in investment banking, combined with stable or growing NII, has bolstered profits for many GSIBs, even as they navigate regulatory requirements and market uncertainties.
The top contributor and detractor to GSIB’s performance was Barclays PLC - Sponsored ADR, which increased by 69.72%, and Société Generale SA, which declined 1.10%.

Factors Affecting Performance [Text Block]
HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes Gold Miners ETF (AUMI) launched December 13, 2023 and has seen a 50.48% return since inception. AUMI seeks to track the Solactive Global Pure Gold Miners Index (SOLGLPGM), which identifies the largest 30 companies by market capitalization that derive their revenues from gold mining. AUMI seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the SOLGLPGM Index.
Overall, gold mining stocks have performed exceptionally well this year, largely driven by the rising price of gold, which as of September surged to over $2,600 per ounce. The increase in gold prices has been fueled by global economic uncertainty, inflationary pressures, and geopolitical tensions, all of which have bolstered demand for gold as a safe-haven asset. Additionally, central bank purchases of gold and a weaker U.S. dollar have further supported the metal’s price, leading to strong profitability for gold mining companies and boosting the performance of related stocks.
The top contributor and detractor to AUMI’s performance included IAMGOLD, which increased by 123.31%, and Gold Resources LTD, which declined 0.26%.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes Lithium & Battery Metal Miners ETF (LIMI) launched September 24, 2024 and has seen a 22.44% return since inception. LIMI seeks to track the BITA Global Lithium and Battery Metals Index (BGLISI), which identifies companies that derive their revenues from lithium and battery metals mining, explorations, refining, and royalties. LIMI seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the BGLISI Index.
Lithium mining stocks have performed exceptionally well this year, driven by the growing demand for electric vehicles (EVs) and renewable energy storage. With lithium prices hovering around $10,400 per ton in September, the battery metal remains a crucial component for EV batteries. The global shift toward clean energy, coupled with government incentives for EV production and adoption, has intensified the demand for lithium. Supply chain bottlenecks and production challenges have kept lithium prices elevated, further boosting the profitability of lithium mining stocks.
The top contributor and detractor to LIMI’s performance included Tianqi Lithium Corp - A, which increased by 28.62%, and Canada Nickel Co. Inc., which declined 3.71%.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes Natural Monopoly ETF (CZAR) launched December 13, 2023 and has seen an 18.71% return since inception. CZAR seeks to track the Solactive Natural Monopoly Index (SOLNMONN), which identifies the top 5 companies within 19 different sectors that have: (1) High Sales, (2) Stable Profitability, (3) Stable Return on Equity, (4) Operational Efficiency and (5) Reinvestment of Profits. CZAR seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the SOLNMONN Index.
Natural monopoly stocks have seen strong performance this year as investors increasingly turn to stable, income-generating sectors amid market volatility. Natural monopolies—industries where a single provider is most efficient due to high infrastructure costs and economies of scale, such as utilities, railroads, and some telecommunications—offer steady, predictable cash flows. With rising inflation and economic uncertainty, these sectors are attractive for their defensive qualities and potential for inflation-linked revenue. Additionally, increased government spending on infrastructure and regulatory support has bolstered these companies.
The top contributor and detractor to CZAR’s performance included Meta Platforms Inc - Class A, which increased by 71.52%, and Open Text Corp, which declined 18.94%.

The Themes Silver Miners ETF (AGMI) launched May 3, 2024 and has seen a 16.01% return since inception. AGMI seeks to track the STOXX Global Silver Miners Index (STXSILVV), which identifies companies that derive their revenues from silver mining. AGMI seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the STXSILVV Index.
Silver mining stocks have seen strong gains this year, supported by the rising price of silver, which has hovered between $24 to $31 per ounce since the fund’s inception in May 2024. Silver’s performance has been driven by increased industrial demand, particularly from the renewable energy and electronics sectors, where silver is a key component. Additionally, inflation concerns and market volatility have pushed investors toward precious metals as a hedge, benefiting silver alongside gold. The combination of robust industrial use and safe haven buying has contributed to the performance of silver mining stocks.
The top contributor and detractor to AGMI’s performance included Newmont Corp, which increased by 32.90%, and Industrias Penoles SAB DE CV, which declined 10.78%.

The Themes Uranium & Nuclear ETF (URAN) launched September 24, 2024 and has seen a 5.64% return since inception. URAN seeks to track the BITA Global Uranium and Nuclear Select Index (BGUNSI), which identifies companies that derive their revenues from uranium mining, explorations, refining, processing, and royalties, as well as nuclear energy, equipment, technology, and infrastructure. URAN seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the BGUNSI Index.
Uranium and nuclear energy stocks have surged this year, fueled by growing demand for clean and reliable energy. With uranium prices climbing above $70 per pound in September 2024, the highest in over a decade, nuclear energy has regained attention as countries push toward low-carbon energy solutions. Governments around the world, including the U.S. and China, are investing heavily in expanding nuclear capacity to meet energy transition goals, driving up demand for uranium. Supply constraints, along with geopolitical uncertainties, have also played a role in pushing uranium prices higher, further boosting the performance of related mining and nuclear energy stocks.
The top contributor and detractor to URAN’s performance included Chengdu Guoguang Electric - A, which increased by 38.53%, and Uranium Energy Corp, which declined 3.72%.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes US Cash Flow Champions ETF (USCF) was launched on December 13, 2023 and has seen a 20.80% return since inception. USCF seeks to track the Solactive US Cash Flow Champions Index (SOLUCFCT), which identifies the top 75 large/mid capitalization companies with the highest 3 years of positive cash flow yield. USCF seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the SOLUCFCT Index.
U.S. Cash Flow stocks have performed well this year as companies with strong cash flow become increasingly attractive in a volatile economic environment. With persistent inflationary pressures and rising costs, investors have been favoring firms that generate steady, high cash flows, which can provide a buffer against economic downturns. Additionally, as the Federal Reserve signaled a potential pause in interest rate hikes, companies with healthy cash positions are less affected by borrowing costs, further boosting their appeal.
The top contributor and detractor of USCF’s performance included Broadcom Inc, which increased by 60.72%, and Humana, which declined 34.32%.

Factors Affecting Performance [Text Block]
HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes US Infrastructure ETF (HWAY) launched September 12, 2024 and has seen an 8.31% return since inception. HWAY seeks to track the Solactive United States Infrastructure Index (SOLUSIST), which identifies 100 US infrastructure companies that derive their revenues from either:(1) Building Materials & Equipment, (2) Construction, (3) Logistics or (4) Engineering Services. HWAY seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the SOLUSIST Index.
U.S. infrastructure stocks have gained momentum this year, driven by increased government investment in rebuilding and modernizing American infrastructure. The passing of substantial federal legislation, including the Infrastructure Investment and Jobs Act, has earmarked billions for projects like roads, bridges, clean energy, and broadband expansion. This influx of funding benefits companies involved in construction, engineering, utilities, and materials, all key holdings in infrastructure-focused ETFs.
The top contributor and detractor to HWAY’s performance included Caterpillar Inc, which increased by 15.18%, and Norfolk Southern Corp, which declined 2.39%.

Factors Affecting Performance [Text Block]
HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes US R&D Champions ETF (USRD) was launched December 13, 2023 and has seen a 24.56% return since inception. USRD seeks to track the Solactive US R&D Champions Index (SOLURDCT), which identifies 50 profitable R&D companies with (1) 3 years of Increasing R&D Spending, (2) 3 years of Positive Return on Equity (ROE), and (3) Positive Profit Margins. USRD seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the SOLURDCT Index.
US R&D stocks have seen strong performance in 2024 due to several favorable economic and market factors. Companies with substantial R&D investment tend to have stronger competitive advantages, creating valuable intellectual property and improving long-term growth potential. This makes them attractive to investors, especially as global innovation and technology continue to expand. Additionally, many R&D-heavy companies, especially in the U.S., have benefited from recent government policies supporting technology and infrastructure, such as the CHIPS Act, which boosts domestic tech manufacturing. Furthermore, U.S. markets overall have been relatively resilient, supported by stable earnings and reduced inflation, which has allowed the Federal Reserve to maintain a less aggressive stance on interest rates. This environment has driven investor interest toward growth-focused sectors like technology and healthcare, where R&D spending is traditionally high.
The top contributor and detractor of USRD’s performance included Nvidia, which increased by 86.91%, and Super Micro Computer Inc, which declined 23.03%.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
The Themes US Small Cap Cash Flow Champions ETF (SMCF) was launched on December 13, 2023 and has seen a 23.74% return since inception. SMCF seeks to track the Solactive US Small Cap Cash Flow Champions Index (SOLSUCCT), which identifies the top 75 small capitalization companies with the highest 3 years of positive cash flow yield. SMCF seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the SOLSUCCT Index.
Small-cap cash flow stocks have seen solid performance this year, benefiting from favorable economic factors. The Federal Reserve’s recent rate cuts have reduced borrowing costs, which is particularly beneficial for small-cap companies that rely more heavily on debt financing to fuel growth. Strong consumer spending has further boosted revenues for many small-cap companies in sectors like retail, technology, and consumer services. Additionally, SMCF’s exposure to regional banks—some of which are key holdings—has helped drive returns as these banks have rebounded with improved lending conditions and better profitability in a lower-rate environment.
The top contributor and detractor of SMCF’s performance included Williams-Sonoma Inc, which increased by 58.76%, and APA Corp, which declined 28.12%.
