PART I

Our Company

We are the only publicly-traded asset management company that focuses exclusively on ETPs. We were the eighth largest ETP sponsor in the world based on assets under management, or AUM, with AUM of $52.4 billion globally as of December 31, 2015. An ETP is a pooled investment vehicle that holds a basket of securities, financial instruments or other assets and generally seeks to track (index-based) or outperform (actively managed) the performance of a broad or specific equity, fixed income or alternatives market segment, or a basket of or a single commodity or currency (or an inverse or multiple thereof). ETPs are listed on an exchange with their shares traded in the secondary market at market prices, generally at approximately the same price as the net asset value of their underlying components. ETP is an umbrella term that includes ETFs, exchange-traded notes and exchange-traded commodities.

Our U.S. listed ETFs make up the vast majority of our global AUM, and are discussed in more detail below. As of December 31, 2015, we were the fifth largest ETF sponsor in the United States by AUM. Our family of ETFs includes funds that track our own indexes, funds that track third party indexes and actively managed funds. We distribute our ETFs through all major channels within the asset management industry, including brokerage firms, registered investment advisers and institutional investors.

We focus on creating ETFs for investors that offer thoughtful innovation, smart engineering and redefined investing. Most of our index-based funds employ a fundamentally weighted investment methodology, which weights securities on the basis of factors such as dividends or earnings, whereas most other ETF industry indexes use a capitalization weighted methodology. In addition, we also offer actively managed ETFs, which are ETFs that are not based on a particular index but rather are actively managed with complete transparency into the ETF’s portfolio on a daily basis. Our broad regulatory exemptive relief enables us to use our own indexes for certain of our ETFs and actively manage other ETFs.

Our AUM has been growing and reaching record levels each year, which has helped improve our profitability. The following charts reflect key operating and financial metrics for our business:

Table of Contents

The following charts reflect the distribution and asset mix of our U.S. listed ETFs as of December 31, 2015:

Approximately 60% of our AUM have been gathered in two of our U.S. listed ETFs – WisdomTree Europe Hedged Equity Fund (HEDJ) and WisdomTree Japan Hedged Equity Fund (DXJ) – which invest in European or Japanese equities, respectively, using our fundamentally weighted approach and, in addition, hedge exposure to the Euro or Yen. These two products also accounted for approximately 60% of our revenues in 2015.

Our Industry

An ETF is an investment fund that holds securities such as equities or bonds and/or other assets such as derivatives or commodities, and generally trades at approximately the same price as the net asset value of its underlying components over the course of the trading day. ETFs offer exposure to a wide variety of asset classes and investment themes, including domestic, international and global equities, and fixed income securities, as well as securities in specific industries and countries. There are also ETFs that track certain specific investments, such as commodities, real estate or currencies.

Table of Contents

We believe ETPs, the vast majority of which are comprised of ETFs, have been one of the most innovative investment products to emerge in the last two decades in the asset management industry. As of December 31, 2015, there were approximately 1,800 ETPs in the United States with aggregate AUM of $2.1 trillion. The chart below reflects the AUM of the global ETP industry since 2001:

As of December 31, 2015, we were the fifth largest ETF sponsor in the U.S. and the eighth largest ETP sponsor in the world by AUM:

According to Morningstar, Inc., ETFs were initially marketed primarily to institutional investors. However, today, institutional investors account for only about half of the assets held in ETFs. ETFs have become more popular among a broad range of investors as they come to understand the benefits of ETFs and use them for a variety of purposes and strategies, including low cost index investing and asset allocation, access to specific asset classes, protective hedging, income generation, arbitrage opportunities and diversification.

While ETFs are similar to mutual funds in many respects, they have some important differences as well:

ETFs are used in various ways by a range of investors, from conservative to speculative uses including:

ETFs are one of the fastest growing sectors of the asset management industry. According to the Investment Company Institute, since 2007 ETFs have generated approximately 60% of the total inflows into ETFs and long-term mutual funds. However, during that time ETFs generated positive inflows into equity funds of approximately $1.1 trillion and long-term equity mutual funds experienced outflows of approximately $356 billion. We believe this trend is due to the inherent benefits of ETFs, that is: transparency, liquidity and tax efficiency.

We believe our growth, and the growth of the ETF industry in general, will continue to be driven by the following factors:

Our Competitive Strengths

Our product development strategy comes from two competitive advantages:

We believe that our expertise in product development combined with our self-indexing capabilities and regulatory exemptive relief provides a strategic advantage, enabling us to launch innovative ETFs that others may not be able to launch as quickly.

Our Growth Strategies

Our goal is to become one of the top five ETF sponsors in the world. In 2009, we were the eleventh largest ETF sponsor in the U.S. based on AUM. We increased our AUM to become the eighth largest U.S. ETF sponsor in 2010, the seventh largest in 2012 and the fifth largest in 2015, with $51.6 billion in AUM. We believe our continued execution will enable us to increase trading volumes and build longer performance track records, which should allow us to attract additional investors and, in turn, further grow our AUM. We will seek to increase our market share and build additional scale by continuing to implement the following growth strategies:

As ETFs are increasingly traded globally, we believe that international expansion of our marketing, communication and sales strategies will provide significant new growth avenues to participate in new regional markets as well as increasing cross-border investments by non U.S. institutional investors. In

Regulatory Framework of the ETF Industry

Not all ETPs are ETFs. ETFs are a distinct type of security with features that are different than other ETPs. ETFs are open-end investment companies or unit investment trusts regulated by the Investment Company Act of 1940, or the Investment Company Act. This regulatory structure is designed to provide investor protection within a pooled investment product. For example, the Investment Company Act requires that at least 40% of the Trustees for each ETF must not be affiliated persons of the fund’s investment manager, or Independent Trustees. If the ETF seeks to rely on certain rules under the Investment Company Act, a majority of the Trustees for that ETF must be Independent Trustees. In addition, as discussed below, ETFs have received orders from the staff of the SEC which exempt them from certain provisions of the Investment Company Act; however, ETFs generally operate under regulations that prohibit affiliated transactions, are subject to standard pricing and valuation rules and have mandated compliance programs. ETPs can take a number of forms in addition to ETFs, including exchange traded notes, grantor trusts or limited partnerships. In the U.S. market, a key factor differentiating ETFs, grantor trusts and limited partnerships from exchange traded notes is that the former hold assets underlying the ETP. Exchange traded notes, on the other hand, are debt instruments issued by the exchange traded note sponsor. Also, each of these structures has implications for taxes, liquidity, tracking error and credit risk.

Because ETFs do not fit into the regulatory provisions governing mutual funds, ETF sponsors need to obtain “exemptive relief” from the SEC from certain provisions of the Investment Company Act in order to operate ETFs. This exemptive relief allows the ETF sponsor to bring to market the specific products or structures for which the relief was requested and obtained. Applying for exemptive relief can be costly and take several months to several years depending on the type of exemptive relief sought. See “Business—Regulation” below.

Our U.S. Listed Products

As of December 31, 2015, we offered a comprehensive family of 86 ETFs.

International Hedged Equity ETFs

In December 2009, we launched the industry’s first currency hedged equity ETFs and currently have 23 such ETFs in the market. These ETFs provide exposure to a specified international equity market while hedging the currency exposure of that market relative to the U.S. dollar. Our international hedged equity ETFs are sub-advised by Mellon Capital.

Table of Contents

Equity ETFs

We offer equity ETFs that provide access to the securities of large, mid and small-cap companies located in the United States, international developed markets and emerging markets, as well as particular market sectors and styles. Our equity ETFs track our own indexes, the majority of which are fundamentally weighted as opposed to market capitalization weighted indexes, which assign more weight to stocks with the highest market capitalizations. These fundamentally weighted indexes focus on securities of companies that pay regular cash dividends or on securities of companies that have generated positive cumulative earnings over a certain period. We believe weighting equity markets by dividends and income, rather than by market capitalization, can provide investors with better risk-adjusted returns over longer term periods in core equity exposures. Our equity ETFs are sub-advised by Mellon Capital, a subsidiary of The Bank of New York Mellon Corporation, or BNY Mellon.

Fixed Income ETFs

In 2010, we began launching international fixed income ETFs that invest in emerging market countries, Asia Pacific ex-Japan countries or European countries. These ETFs are denominated in either local or U.S. currencies. We intend to launch additional fixed income bond funds and broaden our product offerings in this category. In December 2013, we launched a suite of rising rate bond ETFs based on leading fixed income benchmarks we license from third parties and in July 2015, we launched an ETF that seeks to track a yield-enhanced index of U.S. investment grade bonds. Our fixed income ETFs are sub-advised by either Mellon Capital or Western Asset Management, a subsidiary of Legg Mason.

Currency ETFs

We launched the industry’s first currency ETFs in May 2008 using our regulatory exemption for actively managed funds. We offer currency ETFs that provide investors with exposure to developed and emerging markets currencies, including the Chinese Yuan and the Brazilian Real. In December 2013, we launched a U.S. Dollar Bullish Fund licensing a new Bloomberg index. Currency ETFs invest in U.S. money market securities, forward currency contracts and swaps and seek to achieve the total returns reflective of both money market rates in selected countries available to foreign investors and changes to the value of these currencies relative to the U.S. dollar. Our currency ETFs are sub-advised by Mellon Capital and Western Asset Management.

Alternative Strategy ETFs

In 2011, we launched the industry’s first managed futures strategy ETF and a global real return ETF. In 2015, we launched a dynamic long/short U.S. equity ETF and a dynamic bearish U.S. equity ETF. We also intend to explore additional alternative strategy products in the future. Our managed futures strategy ETF and dynamic long/short and bearish U.S. equity ETFs are sub-advised by Mellon Capital and our global real return ETF is sub-advised by Western Asset Management.

Commodity ETFs

In January 2016, we acquired the GreenHaven family of commodity ETFs, which have been renamed the WisdomTree Continuous Commodity Index Fund (NYSE Arca:GCC) and the WisdomTree Coal Fund (NYSE Arca:TONS).

Our Non-U.S. Listed Products

WisdomTree UCITS ETFs

In connection with our acquisition of Boost and the subsequent build out of our European platform, we have listed six WisdomTree branded UCITS ETFs, including 10 additional currency hedged share classes, on the London Stock Exchange, Borsa Italiana, Deutsche Börse and SIX Swiss Exchange, providing exposure to large and small-cap U.S. and European equities and emerging markets. In April 2015, we listed the WisdomTree ISEQ 20^® ETF (ISEQ) on the London Stock Exchange, concurrent to WisdomTree’s merger with the original ISEQ 20^® ETF (IETF).

Boost Short and Leveraged ETPs

As part of the Boost acquisition, we acquired Boost’s short and leveraged fully collateralized equity, commodity, fixed income and currency ETPs, which are listed in Europe. As of December 31, 2015, there were 64 ETPs on the Boost platform.

Sales, Marketing and Research

We distribute our ETFs through all major channels within the asset management industry, including brokerage firms, registered investment advisers and institutional investors. Our primary sales efforts are not directed towards the retail segment but rather are directed towards the financial or investment adviser who acts as the intermediary between the end-client and us. We do not pay commissions nor do we offer 12b-1 fees to financial advisers to use or recommend the use of our ETFs.

We have developed an extensive network and relationships with financial advisers and we believe our ETFs and related research are well structured to meet their needs and those of their clients. Our sales professionals act in a consultative role to provide the financial adviser with value-added services. We seek to consistently grow our network of financial advisers and we opportunistically

11

Table of Contents

seek to introduce new products that best deliver our investment strategies to investors through these distribution channels. We have our own team of 55 sales professionals located in the United States as of December 31, 2015. We plan to continue to increase our sales force and invest in sales-related resources over the course of 2016 to further penetrate existing sales channels, and to better service new emerging distribution channels.

In addition, we have agreements with third parties to serve as the external marketing agents for the WisdomTree ETFs in Latin America, Australia, New Zealand and Israel as well as with E*Trade Financial and Charles Schwab & Co. to allow certain of our ETFs to trade commission free on their brokerage platforms in exchange for a percentage of our advisory fee revenues from certain AUM. We believe these arrangements expand our distribution capabilities in a cost-effective manner and we may continue to enter into such arrangements in the future.

Our marketing efforts are focused on three objectives: generating new clients and inflows to our ETFs; retaining existing clients, with a focus on cross-selling additional WisdomTree ETFs; and building brand awareness. We pursue these objectives through a multi-faceted marketing strategy targeted at financial advisers. We utilize the following strategies:

We will continue to evolve our marketing and communication efforts in response to changes in the ETF industry, market conditions and marketing trends.

Our research team has three core functions: index development and oversight, investment research and sales support. In its index development role, the research group is responsible for creating the investment methodologies and overseeing the maintenance of our indexes that the WisdomTree ETFs are designed to track. The team also provides a variety of investment research around these indexes and market segments. Our research is typically academic-type research to support our products, including white papers on the strategies underlying our indexes and ETFs, investment insights on current market trends, and types of investment strategies that drive long-term performance. We distribute our research through our sales professionals, online through our website and blog, targeted emails to financial advisers, or through financial media outlets. On some occasions, our research has been included in “op-ed” articles appearing in the Wall Street Journal. Shorter research notes are also developed to promote our ideas, which are distributed online through social media channels. Finally, the research team supports our sales professionals in meetings as market experts and through custom analysis on client portfolio holdings. In addition, we consult with our senior investment strategy adviser, Professor Jeremy Siegel, on product development ideas and market commentaries.

Product Development

We are focused on driving continued growth through innovative product development. Due to our broad based regulatory exemptive relief, proprietary index development capabilities and a strategic focus on product development at the senior management level, we have demonstrated an ability to launch innovative and differentiated ETFs. When developing new funds, we seek to introduce product that can be first to market, offer improvement in structure or strategy relative to an incumbent product or offer some other key distinction relative to an incumbent product. In short, we want to add choice in the market and seek to introduce thoughtful investment solutions by avoiding commoditized products. Lastly, when launching new products we seek to expand and diversify our overall product line.

Competition

The asset management industry is highly competitive and we face substantial competition in virtually all aspects of our business. Factors affecting our business include fees for our products, investment performance, brand recognition, business reputation, quality of service and the continuity of our financial adviser relationships. We compete directly with other ETF sponsors and mutual fund companies and indirectly against other investment management firms, insurance companies, banks, brokerage firms and other financial institutions that offer products that have similar features and investment objectives to those offered by us. The vast majority of the firms we compete with are subsidiaries of large diversified financial companies and many others are much larger in terms of AUM, years in operations and revenues and, accordingly, have much larger sales organizations and budgets. In addition, these larger competitors may attract business through means that are not available to us, including retail bank offices, investment banking, insurance agencies and broker-dealers.

The ETF industry is becoming significantly more competitive. Certain existing players have chosen to compete on price in commoditized categories. In addition, we have witnessed existing players broaden their suite of products to different strategies that are, in some cases, similar to ours. Lastly, large traditional asset managers are also launching ETFs, some with similar strategies to ours.

We do not know what effect, if any, the launch of these ETFs or price cuts may have on our business. Within the ETF industry, being a first mover, or one of the first providers of ETFs in a particular asset class, can be a significant advantage, as the first ETF in a category to attract scale in AUM and trading liquidity is generally viewed as the most attractive ETF. We believe that our early launch of ETFs in a number of asset classes or strategies, including fundamental weighting and currency hedging, positions us well to maintain our position as one of the leaders of the ETF industry. Additionally, we believe our affiliated indexing or “self-indexing” model enables us to launch proprietary products which do not have exact competition.

We believe our ability to successfully compete will depend largely on our competitive product structure and our ability to offer exposure to compelling investment strategies, develop distribution relationships, create new investment products, build trading volume, AUM and outperforming track records in existing funds, offer a diverse platform of investment choices, build upon our brand and attract and retain talented sales professionals and other employees.

U.S. Regulation

The investment management industry is subject to extensive regulation and virtually all aspects of our business are subject to various federal and state laws and regulations. These laws and regulations are primarily intended to protect investment advisory clients and shareholders of registered investment companies. These laws generally grant supervisory agencies broad administrative powers, including the power to limit or restrict the conduct of our business and to impose sanctions for failure to comply with these laws and regulations. Further, such laws and regulations may provide the basis for litigation that may also result in significant costs to us.

We are currently subject to the following laws and regulations, among others. The costs of complying with such laws and regulations have increased and will continue to contribute to the costs of doing business:

13

Table of Contents

With respect to ETFs registered under the ICA, because such ETFs do not fit into the regulatory provisions governing mutual funds, ETF sponsors need to obtain from the SEC exemptive relief from certain provisions of the ICA in order to operate ETFs. This exemptive relief allows the ETF sponsor to bring products to market for the specific products or structures for which the relief was requested and obtained. Applying for exemptive relief can be costly and take several months to several years depending on the type of exemptive relief sought. In addition, each WisdomTree ETF is listed on a secondary market, (each, an Exchange) and any new WisdomTree ETF will seek listing on an Exchange. While the SEC has already approved rules for Exchanges to allow index-based ETFs to list that meet prescribed requirements (e.g., minimum number, market value and trading volume of securities in the new ETF’s benchmark index), these rules do not allow any actively managed ETFs or index-based ETFs that do not meet the prescribed requirements without specific SEC approval. The SEC approval process has historically taken months to complete and, in some cases, years. The SEC may ultimately determine not to allow such potential new WisdomTree ETFs or may require strategy modifications prior to approval.

FINRA rules and guidance may affect how WisdomTree ETFs are sold by member firms. Although WisdomTree currently does not offer so-called leveraged ETFs in the U.S., which may include within their holdings derivative instruments such as options futures or swaps, recent FINRA guidance on margin requirements and suitability determinations with respect to customers trading in leveraged ETFs may influence how member firms effect sales of certain WisdomTree ETFs, such as our currency ETFs, which also use some forms of derivatives, including forward currency contracts and swaps, our international hedged equity ETFs, which use currency forwards, and our rising rates bond ETFs and alternative strategy ETFs, which use futures. In September 2015, FINRA issued an investor alert to help investors better understand “smart beta” products, or products that are linked to and seek to track the performance of alternatively weighted indices.

Finally, our common stock is traded on the NASDAQ Global Select Market and we are therefore also subject to their rules including corporate governance listing standards, as well as federal and state securities laws. In addition, the WisdomTree ETFs are listed on NYSE Arca, the NASDAQ Market and the BATS Exchange, and accordingly are subject to the listing requirements of those exchanges.

Non-U.S. Regulation

Our operations outside the U.S. are subject to the laws and regulations of various non-U.S. jurisdictions and non-U.S. regulatory agencies and bodies. As we continue to expand our international presence, a number of our subsidiaries and international operations have become subject to regulatory systems, in various jurisdictions, comparable to those covering our operations in the U.S. Regulators in these non-U.S. jurisdictions may have broad authority with respect to the regulation of financial services including, among other things, the authority to grant or cancel required licenses or registrations.

Irish and European Regulation

In connection with our acquisition of Boost and the subsequent build out of our European platform, we are subject to Irish and European regulation of our WisdomTree UCITS ETFs and Boost ETPs as follows:

WisdomTree UCITS ETFs

The investment management industry in Ireland is subject to both Irish domestic law and European Union law. The Central Bank of Ireland, or the Central Bank, is responsible for the authorization and supervision of collective investment schemes, or CIS, in Ireland. CIS’s are also commonly known as funds/schemes. There are two main categories of funds authorized by the Central Bank, UCITS (Undertaking for Collective Investment in Transferable Securities) and funds that are not UCITS. ETFs form part of the Irish and European regulatory frameworks that govern UCITS, with ETFs having been the subject of specific consideration at European level (which is then repeated and/or interpreted by the Central Bank in its UCITS Notices and Guidance Notes).

One of our subsidiaries, WisdomTree Management Limited, is an Ireland based investment manager providing investment and other management services to WisdomTree Issuer plc, or WTI, and WisdomTree UCITS ETFs. The WisdomTree UCITS ETFs are issued by WTI. WTI, a non-consolidated third party, is a public limited company organized in Ireland and is authorized as a UCITS by the Central Bank. All UCITS have their basis in EU legislation and once authorized in one European Economic Area, or EEA, Member State, may be marketed throughout the EU, without further authorization. This is described as an EU passport.

WTI is established and operated as a public limited company with segregated liability between its sub-funds. The sub-funds are segregated portfolios, each with their own investment objective and policies and assets. Each sub-fund has a separate authorization from the Central Bank, and each is authorized as an ETF. Each sub-fund tracks a different index. The index must comply with

14

Table of Contents

regulatory criteria that govern, among others, the eligibility and diversification of its constituents, and the availability of information on the index such as the frequency of calculation of the index, the index’s transparency, its methodology and frequency of calculation. Each sub-fund is listed on the Irish Stock Exchange and has shares admitted to trading on the London Stock Exchange and, typically, on various European stock exchanges and, accordingly, is subject to the listing requirements of those exchanges.

WTI is currently subject to the following legislation and regulatory requirements:

Boost ETPs

One of our subsidiaries, Boost Management Limited, is a Jersey based investment manager providing investment and other management services to Boost Issuer PLC, or BI, and Boost ETPs. The Boost ETPs are issued by BI. BI, a non-consolidated third party, is a public limited company organized in Ireland. It was established as a special purpose vehicle for the purposes of issuing collateralized exchange traded securities, or ETP Securities, under the Collateralized ETP Securities Programme described in its Base Prospectus. BI is not required to be licensed, registered or authorized under any current securities, commodities or banking laws of Ireland and operates without supervision by any authority in any jurisdiction.

The Central Bank, as competent authority under Directive 2003/71/EC (as amended by Directive 2010/73/EU), or the Prospectus Directive, has approved the Base Prospectus as meeting the requirements imposed under Irish and EU law pursuant to the Prospectus Directive. Such approval relates only to ETP Securities which are to be admitted to trading on a regulated market for the purpose of Directive 2004/39/EC of the European Parliament and of the Council on markets in financial instruments (MiFID) and/or which are to be offered to the public in any Member State of the European Economic Area.

The Central Bank has, at the request of BI, notified the approval of the Base Prospectus in accordance with Article 18 of the Prospectus Directive to the U.K. Listing Authority (the United Kingdom financial supervisory authority), the Commissione Nazionale per la Societá e la Borsa (the Italian financial supervisory authority), the Bundesanstalt für Finanzdienstleistungsaufsicht (the German Federal financial supervisory authority) and the Financial Market Authority of Austria, by providing them, inter alia, with certificates of approval attesting that this Base Prospectus has been drawn up in accordance with the Prospectus Directive. BI may request the Central Bank to provide competent authorities in other EEA Member States with such certificates whether for the purposes of making a public offer in such Member States or for admission to trading of all or any ETP Securities on a regulated market therein or both.

BI is currently subject to the following legislation and regulatory requirements:

Japanese Regulation

In February 2016, our Tokyo, Japan-based subsidiary, WisdomTree Japan K.K., or WTJ, became registered as a Type 1 Financial Instruments Business with the Kanto Local Finance Bureau (a part of Japan’s Ministry of Finance under authority delegated by the Financial Services Agency of Japan, or FSA). WTJ also is a member of the Japan Securities Dealers Association and the Japan Investor Protection Fund. Although WTJ has not launched locally listed ETFs in the Japanese market, it will serve the institutional market in Japan selling our U.S. listed ETFs and, as such, is subject to local regulation within the parameters of its Type 1 Business license.

WTJ is currently subject to the following legislation and regulatory requirements:

Intellectual Property

We regard our name, WisdomTree, as material to our business and have registered WisdomTree^® as a service mark with the U.S. Patent and Trademark Office and in various foreign jurisdictions.

Our index-based equity ETFs are based on our own indexes and we do not license them from, nor do we pay licensing fees to, third parties for these indexes. We do, however, license third party indexes for certain of our fixed income, currency and alternative ETFs.

On March 6, 2012, the U.S. Patent and Trademark Office issued to us our patent on Financial Instrument Selection and Weighting System and Method, which is embodied in our dividend weighted equity indexes. We also have two patent applications pending with the U.S. Patent and Trademark office that relate to the operation of our ETFs and our index methodology. There is no assurance that patents will be issued from these applications and we currently do not rely upon our recently issued or future patents for a competitive advantage.

Employees

As of December 31, 2015, we had 177 full-time employees. Of these employees, 55 are engaged in our U.S. sales function, 34 are in Europe and 6 are in Japan, with the remainder providing managerial, finance, marketing, legal, regulatory compliance, operations and research functions for our U.S. business.

Any investment in our common stock involves a high degree of risk. You should consider carefully the specific risk factors described below in addition to the other information contained in this Report before making a decision to invest in our common stock. If any of these risks actually occur, our business, operating results, financial condition and prospects could be harmed. This could cause the trading price of our common stock to decline and a loss of all or part of your investment. Certain statements below are forward-looking statements. See the section entitled “Cautionary Note Regarding Forward-Looking Statements.”

Risks Related to Our Business and Our Industry

Financial growth in recent years may not provide an accurate representation of the financial growth we may experience in the future, which may make it difficult to evaluate our future prospects.

We launched our first 20 ETFs in June 2006. We incurred significant losses following the launch of our first ETFs. We first reported net income in the first quarter of 2011 and we only began to generate positive cash flow on a full quarterly basis in the second fiscal quarter of the year ended December 31, 2010 and, as a result, our historical growth in recent years may not provide an accurate representation of the growth we may experience in the future, which may make it difficult to evaluate our future prospects. Although we have reported net income for the last five fiscal years, we may not be able to maintain or increase our level of profitability. Prior to generating net income for 2011, we incurred net losses of $27.0 million, $21.2 million and $7.5 million in 2008, 2009 and 2010, respectively. Because of the various risks outlined in this Report, we cannot assure you that we will continue to be profitable.

The significant AUM growth we have experienced over the past three years may be difficult to sustain.

Our U.S. listed AUM, which makes up the vast majority of our global AUM, has increased significantly over the last three fiscal years, from $18.3 billion at the end of 2012 to $51.6 billion at the end of 2015. The absolute measure of our AUM represents a significant rate of growth that has been and may continue to be difficult to sustain. Furthermore, as we grow larger and increase our AUM, it may become increasingly difficult to maintain our current rate of growth. In addition, as compared to 17 other traditional publicly traded asset managers, we were ranked number one for our rate of organic growth of 44.8% in 2015. The continued growth of our business will depend on, among other things, devoting sufficient resources to maintain existing investment strategies and to selectively develop new strategies that align with market sentiment. Our business growth will also depend on our success in achieving superior investment performance from our investment strategies, as well as our ability to maintain and extend our distribution capabilities, to deal with changing market conditions, to maintain adequate financial and business controls and to comply with new legal and regulatory requirements arising in response to both the increased sophistication of the investment management industry and the significant market and economic events of the last few years.

Declining prices of securities can adversely affect our business by reducing the market value of the assets we manage or causing WisdomTree ETF shareholders to sell their fund shares and trigger redemptions.

We are subject to risks arising from declining prices of securities, which may result in a decrease in demand for investment products, a higher redemption rate and/or a decline in AUM. The securities markets are highly volatile and securities prices may increase or decrease for many reasons, including general economic conditions, political events, acts of terrorism and other matters beyond our control. Substantially all of our revenues are determined by AUM in equity securities, in both the international and U.S. markets. As a result, our business can be expected to generate lower revenues in declining equity market environments or general economic downturns. A decline in the prices of securities held by the WisdomTree ETFs may cause our revenues to decline by either causing the value of our AUM to decrease, which would result in lower advisory fees, or causing investors in the WisdomTree ETFs to sell their shares in favor of investments they perceive to offer greater opportunity or lower risk, thus triggering redemptions that would also result in decreased AUM and lower fees.

Fluctuations in the amount and mix of our AUM may negatively impact revenues and operating margins.

The level of our revenues depends on the amount and mix of our AUM. Our revenues are derived primarily from advisory fees based on a percentage of the value of our AUM and vary with the nature of the ETFs, which have different fee levels. Fluctuations in the amount and mix of our AUM may be attributable in part to market conditions outside of our control that have had, and in the future could have, a negative impact on our revenues and operating margins.

Withdrawals or broad changes in investments in our ETFs by investors with significant positions may negatively impact revenues and operating margins.

We have had in the past, and may have in the future, investors who maintain significant positions in one or more of our ETFs. If such an investor were to broadly change or withdraw its investments in our ETFs because of a change to its investment strategy, market conditions or any other reason, it may significantly change the amount and mix of our AUM, which may negatively affect our revenues and operating margins.

We derive a substantial portion of our revenues from two products that are invested in securities of Japanese and European companies, with a currency hedge, and as a result, our operating results are particularly exposed to the performance of these funds and our ability to maintain the AUM of these funds, as well as investor sentiment toward investing in the funds’ strategies and market-specific political and economic risk.

At December 31, 2015, approximately 62% of our U.S. listed ETF AUM was concentrated in two of our WisdomTree ETFs, with 33% in WisdomTree Europe Hedged Equity Fund (HEDJ) and 29% in WisdomTree Japan Hedged Equity Fund (DXJ). As a result, our operating results are particularly exposed to the performance of these funds and our ability to maintain the AUM of these funds, as well as investor sentiment toward investing in the funds’ strategies. We are also subject to political, economic and market risks in either of these markets and to a weakening of the U.S. dollar relative to the Euro or Yen. If the AUM in these funds were to decline, either because of declining market values or net outflows from these funds, our revenues would be adversely affected.

Most of our AUM is held in ETFs that invest in foreign securities and we therefore have substantial exposure to foreign market conditions and are subject to currency exchange rate risks.

Many of our ETFs invest in securities of companies, governments and other organizations located outside the United States and at December 31, 2015, approximately 82% of our AUM was held by these ETFs. Therefore, the success of our business is closely tied to market conditions in foreign markets. Investments in non-U.S. issuers are affected by political, social and economic uncertainty affecting a country or region in which we are invested. In addition, fluctuations in foreign currency exchange rates could reduce the revenues we earn from certain foreign invested ETFs. This occurs because an increase in the value of the U.S. dollar relative to non-U.S. currencies may result in a decrease in the dollar value of the AUM in these ETFs, which, in turn, would result in lower revenues. Furthermore, investors are likely to believe certain foreign invested ETFs, as well as certain of our currency and fixed income ETFs, are a less attractive investment opportunity when the value of the U.S. dollar rises relative to non-U.S. currencies, which could have the effect of reducing investments in these ETFs, thus reducing revenues. Conversely, a weakening U.S. dollar may make less attractive our international hedged equity ETFs, as unhedged alternatives would benefit from the appreciation of the foreign currency or currencies while our hedged ETFs would not, which could result in redemptions in our funds. Since a substantial portion of our AUM at December 31, 2015 was held in our international hedged equity ETFs, a weakening of the U.S. dollar relative to the Euro or Yen may adversely affect our AUM and revenues.

Many of our WisdomTree ETFs have a limited track record and poor investment performance could cause our revenues to decline.

Many of our ETFs have a limited track record upon which an evaluation of their investment performance can be made. At December 31, 2015, of our total 86 ETFs, 46 had at least a three year track record, 41 had at least a five year track record and none had a ten year track record. Furthermore, as part of our strategy, we continuously evaluate our product offerings to ensure that all of our funds are useful, compelling and differentiated investment offerings, to more competitively align our overall product line in the current ETF landscape and to reallocate our attention and resources to areas of greater client interest. As a result, we may further adjust our product offering, which may result in the closing of some of our ETFs, changing their investment objective or offering of new funds. The investment performance of our funds is important to our success. While strong investment performance could stimulate sales of our ETFs, poor investment performance, on an absolute basis or as compared to third party benchmarks or competitive products, could lead to a decrease in sales or stimulate redemptions, thereby lowering the AUM and reducing our revenues. Our fundamentally-weighted equity ETFs are designed to provide the potential for better risk-adjusted investment returns over full market cycles and are best suited for investors with a longer-term investment horizon. However, the investment approach of our equity ETFs may not perform well during certain shorter periods of time during different points in the economic cycle.

We currently depend on State Street Bank and Trust Company to provide us with critical administrative services to operate our business and the WisdomTree ETFs. The failure of State Street to adequately provide such services could materially affect our operating business and harm WisdomTree ETF shareholders.

We currently depend upon State Street Bank and Trust Company, or State Street, to provide the WisdomTree Trust with custody services, fund accounting, administration, transfer agency and securities lending services. The failure of State Street to successfully provide us and the WisdomTree ETFs with these services could result in financial loss to us and WisdomTree ETF shareholders. In addition, because State Street provides a multitude of important services to us, changing this vendor relationship would be challenging. It might require us to devote a significant portion of management’s time to negotiate a similar relationship with another vendor or have these services provided by multiple vendors, which would require us to coordinate the transfer of these functions to another vendor or vendors.

We depend on BNY Mellon and Western Asset Management to provide portfolio management services and other third parties to provide many critical services to operate our business and the WisdomTree ETFs. The failure of key vendors to adequately provide such services could materially affect our operating business and harm WisdomTree ETF shareholders.

We depend on third party vendors to provide us with many services that are critical to operating our business, including BNY Mellon and Western Asset Management, as sub-advisers that provide us with portfolio management services, third party providers of index calculation services for our indexes, a distributor of the WisdomTree ETFs and a third party provider of indicative values of the portfolios of the WisdomTree ETFs. The failure of any of these key vendors to provide us and the WisdomTree ETFs with these services could lead to operational issues and result in financial loss to us and WisdomTree ETF shareholders.

The asset management business is intensely competitive. Many of our competitors have greater market share, offer a broader range of products and have greater financial resources than we do. As a result, we may experience pressures on our pricing and market share.

Our business operates in intensely competitive industry segments. We compete directly with other ETF sponsors and mutual fund companies and indirectly against other investment management firms, insurance companies, banks, brokerage firms and other financial institutions that offer products that have similar features and investment objectives to those offered by us. We compete based on a number of factors, including name recognition, service, investment performance, product features and breadth of product choices, and fees. Several ETF sponsors with whom we directly compete are seeking to obtain market share based on low fees. Many of our competitors have greater market share, offer a broader range of products and have greater financial resources than we do. Some financial institutions operate in a more favorable regulatory environment and/or have proprietary products and distribution channels, which may provide certain competitive advantages to them and their investment products. Our competitors may also adopt products, services or strategies similar to ours, including the use of fundamentally-weighted indexes. In addition, over time certain sectors of the financial services industry have become considerably more concentrated, as financial institutions involved in a broad range of financial services have been acquired by or merged into other firms. This convergence could result in our competitors gaining greater resources and we may experience pressures on our pricing and market share as a result of these factors and as some of our competitors seek to increase market share by reducing prices. We believe that competition within the ETF industry will continue to increase as more traditional asset management companies become ETF sponsors.

Competitive pressures could reduce revenues and profit margins.

The ETF industry is becoming significantly more competitive as existing players broaden their suite of products to different strategies, in some cases, similar to ours. Although the ETF industry currently has a higher barrier to entry as a result of the need for ETF sponsors to obtain exemptive relief from the SEC in order to operate ETFs, traditional asset managers, many of whom are much larger than us, have started to enter the ETF space, and some competitors have launched ETFs using either third party or proprietary fundamentally weighted or factor-based indexes or currency hedged ETFs with fees that are generally equivalent to, and in some instances lower than, our comparable ETFs. We expect that additional companies, both new and traditional asset managers, will continue to enter the ETF space.

There has also been increased price competition in not only commoditized product categories such as traditional, market capitalization weighted index exposures, but also in fundamental or other non-market cap weighted or factor-based exposures. Vanguard, Schwab, iShares and State Street primarily compete in this space and have offered low fee product for many years. However more recently, iShares and State Street have lowered prices across additional funds, or launched new funds at lower price points, along with other new market entrants noted above.

In addition, in 2008, the SEC proposed a rule that, if adopted, would eliminate the need to obtain exemptive relief, thereby lowering the barrier to entry. This proposed rule was never adopted and it is unclear whether a new rule could be proposed in 2016. ETFs that do not meet generic exchange listing standards, such as actively managed ETFs, currently undergo a lengthy exchange listing process, which sometimes takes in excess of a year. In February 2015, the New York Stock Exchange proposed generic listing standards for such ETFs, which would substantially reduce barriers to entry. While this proposal withdrawn in October 2015, it may be re-proposed in 2016.

In addition, in December 2014, the SEC granted Eaton Vance and related parties an exemption from certain provisions of the Investment Company Act to permit the offering of a form of non-transparent exchange traded managed funds. In addition, the SEC rejected proposals from Precidian and BlackRock to also offer a form of non-transparent exchange traded product. Subsequently, Precidian refiled its application with changes intended to address the SEC’s concerns. Non-transparent exchange traded products are expected to launch in 2016 and may allow traditional actively managed mutual fund sponsors to compete more effectively against ETFs, which could reduce our revenues and profit margins.

Our revenues could be adversely affected if the WisdomTree Trust determines that the advisory fees we receive from the WisdomTree ETFs should be reduced.

Our advisory agreements with the WisdomTree Trust and the fees we collect from the WisdomTree ETFs are subject to review and approval by the Independent Trustees of the WisdomTree Trust. The advisory agreements are subject to initial review and approval. After the initial two-year term of the agreement for each ETF, the continuation of such agreement must be reviewed and approved at least annually by a majority of the Independent Trustees. In determining whether to approve the agreements, the Independent Trustees consider factors such as the nature and quality of the services provided by us, the fees charged by us and the costs and profits realized by us in connection with such services, as well as any ancillary or “fall-out” benefits from such services, the extent to which economies of scale are shared with the WisdomTree ETFs, and the level of fees paid by other similar funds. If the Independent Trustees determine that the advisory fees we charge to any particular fund are too high, we will need to reduce our fees, which could adversely affect our revenues.

Our risk management policies and procedures, and those of our third party vendors upon which we rely, may not be fully effective in identifying or mitigating risk exposure, including employee misconduct. If our policies and procedures do not adequately protect us from exposure to these risks, we may incur losses that would adversely affect our financial condition, reputation and market share.

We have developed risk management policies and procedures and we continue to refine them as we conduct our business. Many of our procedures involve oversight of third party vendors that provide us with critical services such as portfolio management, custody and fund accounting and administration, and index calculation services. Our policies and procedures to identify, monitor and manage risks may not be fully effective in mitigating our risk exposure. Moreover, we are subject to the risks of errors and misconduct by our employees, including fraud and non-compliance with policies. These risks are difficult to detect in advance and deter, and could harm our business, results of operations or financial condition. Although we maintain insurance and use other traditional risk-shifting tools, such as third party indemnification, in order to manage certain exposures, they are subject to terms such as deductibles, coinsurance, limits and policy exclusions, as well as risk of counterparty denial of coverage, default or insolvency. If our policies and procedures do not adequately protect us from exposure and our exposure is not adequately covered by insurance or other risk-shifting tools, we may incur losses that would adversely affect our financial condition and could cause a reduction in our revenues as WisdomTree ETF shareholders shift their investments to the products of our competitors.

Compliance with extensive, complex and changing regulation imposes significant financial and strategic costs on our business, and non-compliance could result in fines and penalties.

Our business is subject to extensive regulation of our business and operations. Our U.S. subsidiary, WisdomTree Asset Management, Inc., or WTAM, is a registered investment adviser and is subject to oversight by the SEC pursuant to its regulatory authority under the Investment Advisers Act. We also must comply with certain requirements under the Investment Company Act, with respect to the WisdomTree ETFs for which WTAM acts as investment adviser. WTAM is also a member of the NFA and registered as a Commodity Pool Operator for certain of our ETFs. In addition, two of our other subsidiaries, WisdomTree Commodity Services, LLC and WisdomTree Coal Services, LLC, are also members of the NFA and registered as Commodity Pool Operators for two of our recently acquired commodity ETFs. As a Commodity Pool Operator, we are subject to oversight by the NFA and the CFTC pursuant to regulatory authority under the Commodity Exchange Act. In addition, the content and use of our marketing and sales materials and of our sales force is subject to the regulatory authority of FINRA. We are also subject to foreign laws and regulatory authorities with respect to operational aspects of our ETFs that invest in securities of issuers in foreign countries and in the offer and/or sales of our ETFs in foreign jurisdictions. Each of the regulatory bodies with jurisdiction over us has regulatory powers dealing with many aspects of our business, including the authority to grant, and, in specific circumstances to cancel, permissions to carry on particular businesses. Our failure to comply with applicable laws or regulations could result in fines, censure, suspensions of personnel or other sanctions, including revocation of our registration as an investment adviser. Even if a sanction imposed against us or our personnel is small in monetary amount, the adverse publicity arising from the imposition of sanctions against us by regulators could harm our reputation and thus result in redemptions from our ETFs and impede our ability to retain WisdomTree ETF shareholders and develop new WisdomTree ETF shareholders, all of which may reduce our revenues.

We face the risk of significant intervention by regulatory authorities, including extended investigation activity, adoption of costly or restrictive new regulations and judicial or administrative proceedings that may result in substantial penalties. Among other things, we could be fined or be prohibited from engaging in some of our business activities. The requirements imposed by our regulators are designed to ensure the integrity of the financial markets and to protect WisdomTree ETF shareholders and our advisory clients, and are not designed to protect our stockholders. Consequently, these regulations often serve to limit our activities, including through WisdomTree ETF shareholder protection and market conduct requirements.

The regulatory environment in which we operate also is subject to modifications and further regulation. Recently, concerns have been raised about ETFs’ possible contribution to market volatility as well as the disclosure requirements applicable to certain types of more complex ETFs. In addition, the SEC has proposed a broad set of reforms regarding data reporting, fund liquidity and derivatives usage that would apply to all registered funds, including ETFs, which may have a negative impact on our existing ETFs (including their operations and/or their performance) and our ability to launch new and innovative ETFs. New laws or regulations, or changes in the enforcement of existing laws or regulations, applicable to us and our clients also may adversely affect our business, and our ability to function in this environment will depend on our ability to constantly monitor and react to these changes. Regulatory uncertainty continues to surround the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which represented a comprehensive overhaul of the financial services regulatory environment and requires federal agencies to implement numerous new rules, which, if adopted, may impose additional regulatory burdens and expenses on our business. Compliance with new laws and regulations may result in increased compliance costs and expenses.

Specific regulatory changes also may have a direct impact on our revenues. In addition to regulatory scrutiny and potential fines and sanctions, regulators continue to examine different aspects of the asset management industry. New regulation, judicial interpretations, revised viewpoints, outcomes of lawsuits against other fund complexes or growth in our ETF assets and/or profitability related to the annual approval process for investment advisory agreements may result in the reduction of fees under these agreements, which would mean a reduction in our revenues.

Our operations outside the U.S. are subject to the laws and regulations of various non-U.S. jurisdictions and non-U.S. regulatory agencies and bodies. As we continue to expand our international presence, a number of our subsidiaries and international operations have become subject to regulatory systems, in various jurisdictions, comparable to those covering our operations in the U.S. Regulators in these non-U.S. jurisdictions may have broad authority with respect to the regulation of financial services including, among other things, the authority to grant or cancel required licenses or registrations.

Damage to our reputation could adversely affect our business.

We believe we have developed a strong brand and a reputation for innovative, thoughtful products, favorable long-term investment performance and excellent client services. The WisdomTree name and brand is a valuable asset and any damage to it could hamper our ability to maintain and grow our AUM and attract and retain employees, thereby having a material adverse effect on our revenues. Risks to our reputation may range from regulatory issues to unsubstantiated accusations. Managing such matters may be expensive, time-consuming and difficult.

Abnormally wide bid/ask spreads and market disruptions that halt or disrupt trading or create extreme volatility could undermine investor confidence in the ETF investment structure and limit investor acceptance of ETFs.

The shares of the WisdomTree ETFs, like the shares of all ETFs, trade on exchanges in market transactions that generally approximate the value of the underlying portfolio of securities held by the particular ETF. Trading involves risks including the potential lack of an active market for fund shares, abnormally wide bid/ask spreads (the difference between the prices at which shares of an ETF can be bought and sold) that can exist for a variety of reasons and losses from trading. These risks can be exacerbated during periods when there is low demand for an ETF, when the markets in the underlying investments are closed, when markets conditions are extremely volatile or when trading is disrupted. This could result in limited growth or a reduction in the overall ETF market and result in our revenues not growing as rapidly as it has in the recent past or even in a reduction of revenues.

We have experienced significant growth in recent years, and if we were unable to manage this growth it could have a material adverse effect on our business.

We have experienced significant growth in recent years, which has placed increased demands on our management and other resources and will continue to do so in the future. We may not be able to maintain or accelerate our current growth rate, manage our expanding operations effectively or achieve planned growth on a timely or profitable basis. Managing our growth effectively will involve, among other things:

If we are unable to manage our growth effectively, there could be a material adverse effect on our ability to maintain or increase revenues and profitability.

Continued growth will require continued investment in personnel, information technology infrastructure and marketing activities, as well as further development and implementation of financial, operational and compliance systems and controls. We may not be successful in implementing all of the processes that are necessary to support our growth. Unless our growth results in an increase in our revenues that is at least proportionate to the increase in our costs associated with this growth, our gross margins and our future profitability will be adversely affected.

Our growth strategy also involves, among other things, launching innovative new products that diversify our product offerings and revenues. This will require us to develop products in areas in which we do not have significant prior experience. We may not be successful in developing new products and if developed and launched, we may not be successful in marketing these new products.

We recently expanded our business into Europe and Japan and may expand into other geographic areas in the international marketplace, which could increase our operational, regulatory and other risks.

In April 2014, we expanded into Europe through the acquisition Boost, and in February 2016, we commenced operations in Japan. In the future, we may expand into other geographic areas. As a result of such expansion, we expect to face increased operational, regulatory, compliance, reputational and foreign exchange rate risks. The failure of our compliance and internal control systems to properly mitigate such additional risks, or of our operating infrastructure to support such expansion, could result in operational failures and regulatory fines or sanctions. If our international products and operations experience any negative results or are perceived negatively in non-U.S. markets, it may also harm our reputation in other markets, including the U.S. market. Future international expansion could require us to incur a number of up-front expenses, including those associated with obtaining regulatory approvals, as well as additional ongoing expenses, including those associated with leases, the employment of additional support staff and regulatory compliance. Operating our business in non-U.S. markets may be more expensive than in the United States. To the

22

Table of Contents

extent that our revenues do not increase to the same degree our expenses increase in connection with our expansion outside the United States, our profitability could be adversely affected. Expanding our business into non-U.S. markets may also place significant demands on our existing infrastructure and employees.

Future strategic transactions, including business combinations, mergers and acquisitions, may occur at any time, be significant in size relative to our assets and operations, result in significant changes in our business and materially and adversely affect our stock price. Additionally, we may expend significant financial, management time and other resources without the consummation of such transactions or the realization of the anticipated benefits.

We believe attractive opportunities for strategic transactions exist, some of which may be material to our operations and financial condition if consummated. We have engaged in the past and expect to continue to engage in the future in strategic discussions that we believe may enable us to strengthen our business, expand and diversify our product offering, increase our AUM or enter into new markets. Such transactions may result in our issuing a significant amount of our common stock or other security that could be dilutive to our stockholders, result in substantial borrowings, result in changes in our board composition and/or management team, constitute a change of control of our Company, lead to significant changes in our product offering, business operations and earning and risk profiles, and/or result in a decline in the price of our common stock.

Even if consummated, such transactions may involve numerous risks, including, among others:

We could be prevented from, or significantly delayed in, achieving our strategic goals if we are unable to successfully integrate acquired businesses. Our ability to complete future strategic transactions depends upon a number of factors that are not entirely within our control, including our ability to identify suitable merger or acquisition candidates, negotiate acceptable terms, conclude satisfactory agreements and secure financing. Our failure to complete strategic transactions or to integrate and manage acquired or combined businesses successfully could materially and adversely affect our business, results of operations and financial conditions.

Our ability to operate effectively could be impaired if we fail to retain or recruit key personnel.

The success of our business and the implementation of our growth strategy are highly dependent on our ability to attract, retain and motivate highly skilled, and sometimes highly specialized, employees, including in particular, operations, product development, research and sales personnel. Our employees may voluntarily terminate their employment at any time. The market for these individuals is extremely competitive and is likely to become more so as additional investment management firms enter the ETF industry. Our compensation methods may not enable us to recruit and retain required personnel. In particular, our use of equity grants as a component of total employee compensation may be ineffective if the market price of our common stock declines. Also, we may need to increase compensation levels, which would decrease our net income or increase our losses. If we are unable to retain and attract key personnel, it could have an adverse effect on our business, results of operations and financial condition.

Changes in U.S. federal income tax law could make some of our products less attractive to investors.

Many of the WisdomTree ETFs seek to obtain the investment return achieved by our proprietary indexes that weigh index components based upon dividends. Even with the recent increase in income tax rates applicable to dividends, corporate dividends continue to enjoy favorable tax treatment under current U.S. federal income tax law. If the income tax rates imposed on dividends were increased further, it may make these WisdomTree ETFs less attractive to investors.

Our expenses are subject to fluctuations that could materially affect our operating results.

Our results of operations are dependent in part on the level of our expenses, which can vary from quarter to quarter. Our expenses may fluctuate primarily as a result of discretionary spending, including additional headcount, marketing, advertising and sales expenses we incur to support our growth initiatives. Accordingly, our results of operation may vary from quarter to quarter.

Any significant limitation, or failure of our technology systems, or of our third party vendors’ technology systems, or any security breach of our information and cyber security infrastructure, software applications, technology or other systems that are critical to our operations could interrupt or damage our operations and result in material financial loss, regulatory violations, reputational harm or legal liability.

We are dependent upon the effectiveness of our own, and our vendors’, information security policies, procedures and capabilities to protect the technology systems used to operate our business and to protect the data that reside on or are transmitted through them. Although we and our third party vendors take protective measures to secure information, our and our vendors’ technology systems may still be vulnerable to unauthorized access, computer viruses or other events that could result in inaccuracies in our information or system disruptions or failures, which could materially interrupt or damage our operations. In addition, technology is subject to rapid change and we cannot guarantee that our competitors may not implement more advanced technology platforms for their products, which could affect our business. Any inaccuracies, delays, system failures or breaches, or advancements in technology, and the cost necessary to address them, could subject us to client dissatisfaction and losses or result in material financial loss, regulatory violations, reputational harm or legal liability, which, in turn, could cause a decline in our earnings or stock price.

We may from time to time in the future be involved in legal proceedings that could require significant management time and attention, possibly resulting in significant expense or in an unfavorable outcome, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

From time to time, we may be subject to litigation. In connection with any litigation in which we are involved, we may be forced to incur costs and expenses in connection with defending ourselves or in connection with the payment of any settlement or judgment or compliance with any injunctions in connection therewith if there is an unfavorable outcome. The expense of defending litigation may be significant. The amount of time to resolve lawsuits is unpredictable and defending ourselves may divert management’s attention from the day-to-day operations of our business, which could adversely affect our business, results of operations, financial condition and cash flows. In addition, an unfavorable outcome in any such litigation could have a material adverse effect on our business, results of operations, financial condition and cash flows.

Catastrophic and unpredictable events could have a material adverse effect on our business.

A terrorist attack, war, power failure, cyber-attack, natural disaster or other catastrophic or unpredictable event could adversely affect our revenues, expenses and operating results by: interrupting our normal business operations; inflicting employee casualties, including loss of our key employees; requiring substantial expenditures and expenses to repair, replace and restore normal business operations; and reducing investor confidence. We have a disaster recovery plan to address certain contingencies, but this plan may not be sufficient in responding or ameliorating the effects of all disaster scenarios. Similarly, these types of events could also affect the ability of the third party vendors that we rely upon to conduct our business, including parties that provide us with sub-advisory portfolio management services custodial, fund accounting and administration services, or index calculation services, to continue to provide these necessary services to us, even though they may also have disaster recovery plans to address these contingencies. If we or our third party vendors are unable to respond adequately or in a timely manner, this failure may result in a loss of revenues and/or increased expenses, either of which would have a material adverse effect on our operating results.

A change of control of our Company would automatically terminate our investment management agreements relating to the WisdomTree ETFs unless the Board of Trustees of the WisdomTree Trust and shareholders of the WisdomTree ETFs voted to continue the agreements. A change in control could occur if a third party were to acquire a controlling interest in our Company.

Under the Investment Company Act, an investment management agreement with a fund must provide for its automatic termination in the event of its assignment. The fund’s board must vote to continue such an agreement following any such assignment and the shareholders of the WisdomTree ETFs must approve the assignment. The cost of obtaining such shareholder approval can be significant and which ordinarily would be borne by us. Similarly, under the Investment Advisers Act, a client’s investment management agreement may not be “assigned” by the investment adviser without the client’s consent.

An investment management agreement is considered under both acts to be assigned to another party when a controlling block of the adviser’s securities is transferred. Under both acts, there is a presumption that a stockholder beneficially owning 25% or more of an adviser’s voting stock controls the adviser and conversely a stockholder beneficially owning less than 25% is presumed not to control the adviser. In our case, an assignment of our investment management agreements may occur if a third party were to acquire a controlling interest in our Company. We cannot be certain that the Trustees of the WisdomTree ETFs would consent to assignments of our investment management agreements or approve new agreements with us if a change of control occurs. And even if such approval were obtained, approval from the shareholders of the WisdomTree ETFs would be required to be obtained; such approval could not be guaranteed and even if obtained, likely would result in significant expense. This restriction may discourage potential purchasers from acquiring a controlling interest in our Company.

We may from time to time be subject to claims of infringement of third party intellectual property rights, which could harm our business.

Third parties may assert against us alleged patent, copyright, trademark or other intellectual property rights to intellectual property that is important to our business. Any claims that our products or processes infringe the intellectual property rights of others, regardless of the merit or resolution of such claims, could cause us to incur significant costs in responding to, defending and resolving such claims, and may divert the efforts and attention of our management from our business. As a result of such intellectual property infringement claims, we could be required or otherwise decide that it is appropriate to:

The occurrence of any of the foregoing could result in unexpected expenses, reduce our revenues and adversely affect our business and financial results.

We have been issued a patent and have applied for other patents, but additional patents may not be issued to us and we may not be able to enforce or protect our patents and other intellectual property rights, which may harm our ability to compete and harm our business.

Although we have a patent and have applied for other patents relating to our index methodology and the operation of our ETFs, these other patents may not be issued to us. In addition, even if issued, our ability to enforce our patents and other intellectual property rights is subject to general litigation risks. While we have been competing without the benefit of these patents being issued, if they are not issued or we cannot successfully enforce them, we may lose the benefit of a future competitive advantage that they would otherwise provide to us. If we seek to enforce our rights, we could be subject to claims that the intellectual property right is invalid or is otherwise not enforceable. Furthermore, our assertion of intellectual property rights could result in the other party seeking to assert alleged intellectual property rights of its own or assert other claims against us, which could harm our business. If we are not ultimately successful in defending ourselves against these claims in litigation, we may be subject to the risks described in the immediately preceding risk factor entitled “We may from time to time be subject to claims of infringement of third party intellectual property rights, which could harm our business.”

Risks Relating to our Common Stock

The market price of our common stock has been and may continue to fluctuate significantly, and you could lose all or part of your investment.

The market price of our common stock has been and may continue to fluctuate widely, depending upon many factors, some of which may be beyond our control, including:

25

Table of Contents

In addition, stock markets in general have experienced volatility that has often been unrelated to the operating performance of a particular company. These broad market fluctuations may adversely affect the trading price of our common stock. Furthermore, in the past, market fluctuations and price declines in a company’s stock have led to securities class action litigations or other derivative stockholder lawsuits. If such a suit were to arise, it could cause substantial costs to us and divert our resources regardless of the outcome.

If equity research analysts issue unfavorable commentary or downgrade our common stock, the price of our common stock could decline.

The trading market for our common stock relies in part on the research and reports that equity research analysts publish about us and our business. We do not control the opinions of these analysts. The price and trading volume of our common stock could decline if one or more equity analysts downgrade our common stock or if analysts issue other unfavorable commentary or cease publishing reports about us or our business.

Future issuances of our common stock could lower our stock price and dilute the interests of existing stockholders.

We may issue additional shares of our common stock in the future, either in connection with an acquisition or for other business reasons. The issuance of a substantial amount of common stock could have the effect of substantially diluting the interests of our current stockholders. In addition, the sale of a substantial amount of common stock in the public market, either in the initial issuance or in a subsequent resale by the target company in an acquisition which received such common stock as consideration or by investors who acquired such common stock in a private placement could have a material adverse effect on the market price of our common stock.

The members of our Board of Directors, their affiliates and our executive officers, as stockholders, can exert significant influence over our Company.

As of December 31, 2015, the members of our Board of Directors and our executive officers, as stockholders, collectively beneficially owned approximately 15.4% of our outstanding common stock. As a result of this ownership, they have the ability to significantly influence all matters requiring approval by stockholders of our Company, including the election of directors. This concentration of ownership also may have the effect of delaying or preventing a change in control of our Company that may be favored by other stockholders. This could prevent transactions in which stockholders might otherwise receive a premium for their shares over current market prices.

Although our directors and officers have a duty of loyalty to us under Delaware law and our certificate of incorporation, transactions that we enter into in which a director or officer has a conflict of interest are generally permissible so long as (i) the material facts relating to the director’s or officer’s relationship or interest as to the transaction are disclosed to our Board of Directors and a majority of our disinterested directors, or a committee consisting solely of disinterested directors, approves the transaction, (ii) the material facts relating to the director’s or officer’s relationship or interest as to the transaction are disclosed to our stockholders and a majority of our disinterested stockholders approves the transaction, or (iii) the transaction is otherwise fair to us. Under our certificate of incorporation, representatives of our stockholders are not required to offer to us any transaction opportunity of which they become aware and could take any such opportunity for themselves or offer it to other companies in which they have an investment, unless such opportunity is expressly offered to them solely in their capacity as a director of ours. The listing requirements of the NASDAQ Global Select Market, upon which our common stock is listed, also require that certain transactions in which a director or officer has a conflict of interest must be considered and approved by our Audit Committee, which consists solely of independent directors.

A provision in our certificate of incorporation and by-laws may prevent or delay an acquisition of our Company, which could decrease the market value of our common stock.

Provisions of Delaware law, our certificate of incorporation and our by-laws may discourage, delay or prevent a merger, acquisition or other change in control that stockholders may consider favorable. These provisions may also prevent or delay attempts by stockholders to replace or remove our current management or members of our Board of Directors. These provisions include:

26

Table of Contents

In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law, which limits business combination transactions with stockholders of 15% or more of our outstanding voting stock that our Board of Directors has not approved. These provisions and other similar provisions make it more difficult for stockholders or potential acquirers to acquire us without negotiation. These provisions may apply even if some stockholders may consider the transaction beneficial to them.

As a result, these provisions could limit the price that investors are willing to pay in the future for shares of our common stock. These provisions might also discourage a potential acquisition proposal or tender offer, even if the acquisition proposal or tender offer is at a premium over the then current market price for our common stock.

The payment of dividends to our stockholders is subject to the discretion of our Board of Directors and may be limited by our financial condition, and any applicable laws.

In November 2014, we commenced a quarterly cash dividend and intend to continue to pay regular dividends to our stockholders. Our Board of Directors may, in its discretion, increase or decrease the level of dividends. Further, our Board of Directors has the discretion to discontinue the payment of dividends entirely. Any determination as to the payment of dividends, as well as the level of such dividends, will depend on, among other things, general economic and business conditions, our level of AUM, our strategic plans, our financial results and condition, new credit facilities or other agreements that could limit the amount of dividends we are permitted to pay and any applicable laws. If, as a consequence of these various limitations and restrictions, we are unable to generate sufficient income from our business, we may need to reduce or eliminate the payment of dividends on our common stock. Any change in the level of our dividends or the suspension of the payment thereof could adversely affect our stock price.

In addition, our Board of Directors is authorized, without stockholder approval, to issue preferred stock with such terms as our Board of Directors may, in its discretion, determine. Our Board of Directors could, therefore, issue preferred stock with dividend rights superior to that of the common stock, which could also limit the payment of dividends on the common stock.

We have no unresolved comments from the SEC staff relating to our periodic or current reports filed with the SEC pursuant to the Exchange Act.

Our principal executive office is located at 245 Park Avenue, New York, New York 10167. We occupy approximately 38,000 square feet of office space under a lease that expires in July 2029. We believe that the space we lease is sufficient to meet our needs until the expiration of the lease.

As an investment adviser, we may be subject to routine reviews and inspections by the SEC, NFA and foreign regulators, as well as legal proceedings arising in the ordinary course of business. We are not currently party to any litigation or other legal proceedings that are expected to have a material impact on our business, financial position, results of operations or cash flows.

Not applicable.

Introduction

We were the eighth largest ETP sponsor in the world (based on AUM), with AUM of $52.4 billion globally as of December 31, 2015. An ETP is a pooled investment vehicle that holds a basket of securities, financial instruments or other assets and generally seeks to track (index-based) or outperform (actively managed) the performance of a broad or specific equity, fixed income or alternatives market segment, commodity or currency (or an inverse or multiple thereof). ETPs are listed on an exchange with their shares traded in the secondary market at market prices, generally at approximately the same price as the net asset value of their underlying components. ETP is an umbrella term that includes ETFs, exchange-traded notes and exchange-traded commodities.

Through our operating subsidiaries, we provide investment advisory and other management services to the WisdomTree ETFs and Boost ETPs collectively offering ETPs covering equity, fixed income, currency, alternatives and commodity asset classes. In exchange for providing these services, we receive advisory fee revenues based on a percentage of the ETPs’ average daily AUM. Our expenses are predominantly related to selling, operating and marketing our ETPs. We have contracted with third parties to provide certain operational services for the ETPs. We distribute our ETPs through all major channels within the asset management industry, including brokerage firms, registered investment advisers, institutional investors, private wealth managers and discount brokers primarily through our sales force. Our sales efforts are not directed towards the retail segment but rather are directed towards financial or investment advisers that act as intermediaries between the end-client and us.

Executive Summary

Our U.S. listed AUM, which makes up the vast majority of our global AUM, has increased significantly over the last three fiscal years, from $18.3 billion at the end of 2012 to $51.6 billion at the end of 2015. The significant growth in AUM was a result of record net inflows in 2013 and 2015. We experience particularly strong inflows when our products align with market sentiment. The significant inflows we experienced in 2013 were in our currency hedged Japanese equity ETF (DXJ). Political and economic policy changes in Japan, in particular the Japanese government’s desire to implement policies that have decreased the value of the Yen, drove increased investor interest in the region and in our Japanese hedged equity ETF. In 2015, our currency hedged European equity ETF (HEDJ) comprised the vast majority of our net inflows and offset the outflows we experienced in emerging markets as the aggressive monetary policy of the European Central Bank weakened the Euro, potentially stimulating the equity markets. We believe our increasing inflow levels and AUM are a result of our innovative product offerings and new product launches to further diversify our product offering, as well as a longer track record for the funds we launched in 2006 and 2007. Our growth strategy seeks to increase our market share of ETF industry inflows through continued product diversification and execution of our marketing and sales strategies.

Our strong operating results have translated into record financial results. Our revenues increased significantly from $149.5 million in 2013 to $298.9 million in 2015 primarily due to higher AUM. Pre-tax income increased from $51.5 million in 2013 to $137.2 million in 2015.

Other business highlights for 2015 include the following:

Background

Market Environment

The economic environment and markets have generally improved over the last three years; however, the markets continue to experience volatility. The following chart reflects the annual returns of the broad based equity indexes over the last three years:

As the chart reflects, the broad based equity market indexes generally have been increasing since 2012, with the exception of emerging markets. In addition, volatility increased beginning in the second half of 2015.

The U.S. ETF industry also has been experiencing generally higher flows as the charts below reflect. In 2015, international equities gathered the majority of net inflows for the year:

Industry Developments

The ETF industry is becoming significantly more competitive. Certain existing players have chosen to compete on price in commoditized categories. In addition, existing players have broadened their suite of products to different strategies that are, in some cases, similar to ours. Lastly, large traditional asset managers are also launching ETFs, some with similar strategies to ours. We do not know what effect, if any, the launch of these ETFs may have on our business. Within the ETF industry, being a first mover, or one of the first providers of ETFs in a particular asset class, can be a significant advantage as the first ETF in a category to attract scale in AUM and trading liquidity is generally viewed as the most attractive ETF. We believe that our early launch of ETFs in a number of asset classes or strategies, including fundamental weighting and currency hedging, positions us well to maintain our position as one of the leaders of the ETF industry. Additionally, we believe our affiliated indexing or “self-indexing” model enables us to launch proprietary products which do not have exact competition.

The SEC has proposed a broad set of reforms regarding data reporting, fund liquidity and derivatives usage that would apply to all registered funds, including ETFs. One of the proposed rules may have a negative impact on our existing ETFs and our ability to launch new and innovative ETFs. In December 2015, the SEC proposed new requirements concerning the use of derivatives and other financial transactions, commonly referred to as the “derivatives rule.” The two most important pieces of this proposal cover limits on derivative exposure and requirements concerning the collateralization of derivative exposure generally. We believe substantially all of our ETFs currently meet the proposed portfolio limitations for derivative transactions. We further believe our ETFs could operate to meet the proposed asset segregation and additional risk management reporting processes and requirements, if adopted. However, the actual costs and related impacts are unclear, and we generally believe the regulatory goal of addressing investor protection through prescriptive requirements that significantly change the current regulatory landscape governing funds’ derivatives use may be neither necessary nor beneficial from an investor protection standpoint and may unnecessarily diminish the investment experience of end-investors in open-end mutual funds and ETFs, among other potential consequences. We may put forward specific recommendations in connection with the SEC’s request for public comment, either directly or through industry channels.

In addition, in April 2015, the Department of Labor proposed a rule that would require financial professionals to abide by a fiduciary standard and act in the best interest of their clients with respect to investments governed by the Employee Retirement Income Security Act (ERISA), such as 401(k) plans and IRAs. Investment advisers registered with the SEC already are held to this standard. However, brokers are primarily held to a suitability standard, which requires them to reasonably believe that any investment recommendation they give is suitable for an investor’s objectives, means and age. When financial professionals are governed by a suitability standard in recommending investments to their clients, we believe that ETFs are competitive with traditional investment products. If the fiduciary standard were to replace the suitability standard, we believe that ETFs’ competitiveness generally will increase due to the inherent benefits of ETFs – transparency and liquidity.

Recent Developments

Market volatility has increased significantly entering 2016. From January 1, 2016 through February 17, 2016, the S&P 500, MSCI EAFE (local currency) and MSCI Emerging Market (U.S. dollar) broad indexes have declined approximately 6.0%, 10.0% and 7.0%, respectively. Our U.S. listed AUM has declined approximately 15.0% from $51.6 billion to $44.0 billion as a result of $4.8 billion of negative market movement and $2.8 billion of net outflows in our ETFs, primarily in HEDJ and DXJ.

In January and February 2016, we repurchased 3.4 million shares of our common stock under our share repurchase program for an aggregate cost of $35.6 million. Currently $40.3 million remains under this program for future purchases.

Components of Revenue

Advisory fees

The majority of our revenues are comprised of advisory fees we earn from our U.S. listed ETFs. We earn this revenue based on a percentage of the average daily value of AUM. Our average daily value of AUM is the average of the daily aggregate AUM of our ETFs as determined by the then current net asset value (as defined under Investment Company Act Rule 2a-4) of such ETFs as of the close of business each day. Our fee percentages for individual U.S. listed ETFs range from 0.12% to 0.95%.

We determine the appropriate advisory fee to charge for our ETFs based on the cost of operating each particular ETF taking into account the types of securities the ETFs will hold, fees third party service providers will charge us for operating the ETFs and our competitors’ fees for similar ETFs. Generally, our actively managed ETFs, along with our emerging markets ETFs, are priced higher than our other index based ETFs.

Each of our ETFs has a fixed advisory fee. In order to increase the advisory fee, we would need to obtain approval from a majority of the ETF shareholders, which may be difficult or not possible to achieve. There also may be a significant cost in obtaining such ETF shareholder approval. We do not need ETF shareholder approval to lower our advisory fee. From time to time, we implement voluntary waivers of a portion of our advisory fee. These waivers may expire without shareholder approval needing to be obtained. In addition, we earn a fee based on daily aggregate AUM of our ETFs in exchange for bearing certain fund expenses not covered by our advisory fee.

Our ETF advisory fee revenues may fluctuate based on general stock market trends, which include market value appreciation or depreciation, currency fluctuations against the U.S. dollar and level of inflows or outflows from our ETFs. In addition, these revenues may fluctuate due to increased competition or a determination by the independent trustees of the WisdomTree ETFs to terminate or significantly alter the funds’ investment management agreements with us.

Other income

Other income includes interest income from investing our corporate cash and fees from licensing our indexes to third parties. These revenues are immaterial to our financial results and we do not expect them to be material in the near term.

Components of Expenses

Our operating expenses consist primarily of costs related to selling, operating and marketing our ETFs as well as the infrastructure needed to run our business.

Compensation and benefits

Employee compensation and benefits expenses are expensed when incurred and include salaries, incentive compensation, and related benefit costs. Virtually all our employees receive incentive compensation that is based on our operating results as well as their individual performance. Therefore, a portion of this expense will fluctuate with our business results. In order to attract and retain qualified personnel, we must maintain competitive employee compensation and benefit plans. In normal circumstances, we expect to experience a general rise in employee compensation and benefit expenses over the long term as we grow; however, the rate of increase should be less than the rate of increase in our revenues.

Also included in compensation and benefits are costs related to equity awards granted to our employees. Our executive management and Board of Directors strongly believe that equity awards are an important part of our employees’ overall compensation package and that incentivizing our employees with equity in the Company aligns the interest of our employees with that of our stockholders. We use the fair value method in recording compensation expense for equity based awards. Under the fair value method, compensation expense is measured at the grant date based on the estimated fair value of the award and is recognized as an expense over the vesting period.

We intend to continue to increase our headcount in 2016 to support our growth and expect our compensation and benefits expense for our U.S. based employees will be between 24% to 28% of U.S. listed revenues in 2016.

34

Table of Contents

Fund management and administration

Fund management and administration expenses are expensed when incurred and are comprised of costs we pay third party service providers to operate our ETFs. Under our advisory agreement with the WisdomTree Trust, the Trustees have approved us and other third parties to provide essential management and administrative services to the Trust and each ETF in exchange for an advisory fee. The costs include:

We are not responsible for extraordinary expenses, taxes and certain other expenses.

BNY Mellon acts as sub-adviser for the majority of our ETFs and, prior to April 2014, also provided fund administration, custody and accounting related services for all the WisdomTree ETFs. In April 2014, we transferred our fund administration, custody and accounting related services to State Street. The fees we pay BNY Mellon, our other sub-advisers and State Street have minimums per fund which range from $25,000 to $50,000 per year with additional fees ranging between 0.015% and 0.18% of average daily AUM at various breakpoint levels depending on the nature of the ETF. In addition, we pay certain costs based on transactions in our ETFs or based on inflow levels. The fees we pay for accounting, tax, transfer agency, index calculation and exchange listing are based on the number of ETFs we have. The remaining fees are based on a combination of both AUM and number of funds, or as incurred.

Marketing and advertising

Marketing and advertising expenses are recorded when incurred and include the following:

Our discretionary advertising comprises the largest portion of this expense and we expect these costs to increase in the future as we continue to execute our growth strategy and compete against other ETF sponsors. In addition, we may incur expenditures in certain periods to attract inflows, the benefit of which may or may not be recognized from increases to our AUM in future periods. However, due to the discretionary nature of some of these costs, they can generally be reduced if there were a decline in the markets.

Sales and business development

Sales and business development expenses are recorded when incurred and includes the following:

35

Table of Contents

Professional and consulting fees

Professional fees are expensed when incurred and consist of fees we pay to corporate advisers including accountants, tax advisers, legal counsel, investment bankers, human resources or other consultants. These expenses fluctuate based on our needs or requirements at the time. Certain of these costs are at our discretion and can fluctuate year to year.

Occupancy, communications and equipment

Occupancy, communications and equipment expense includes costs for our corporate headquarters in New York City. We entered into a new 16 year lease beginning in August 2013 for a larger office facility to support our growth.

Depreciation and amortization

Depreciation and amortization expense results primarily from amortization of leasehold improvements to our office space as well as depreciation on fixed assets we purchase, which is depreciated over five to fifteen years.

Third party sharing arrangements

Third party sharing arrangements expense includes payments to our third party marketing agents in Latin America, Australia, New Zealand and Israel. In addition, this expense includes fees we pay to allow our ETFs to be listed on certain third party platforms.

Acquisition contingent payment

Acquisition contingent payment represents the change in the fair value of the buyout obligation we have to the former shareholders of our European ETP business, which we acquired in April 2014. The buyout obligation is based on a formula that takes into account the AUM in the business, its profitability levels and the trading multiple of our common stock. The fair value of the buyout obligation is based on a scenario based quantitative and qualitative assessment.

Other

Other expenses consist primarily of insurance premiums, general office related expenses, securities license fees for our sales force, public company related expenses, corporate related travel and entertainment and board of director fees, including stock-based compensation related to equity awards we granted to our directors.

Income tax

Income tax expense consists of taxes due to various state and federal authorities on our income. The effective tax rate on our U.S. listed ETF business is approximately 39% and our overall effective tax rate is approximately 43% due to the non-deductibility of losses in our European ETP business. These losses may be recognized in the future after the European business is profitable. Our U.S. rate may change in the future as our share of income attributable to the various states changes. We plan on performing this analysis on an annual basis in connection with the preparation of our U.S. income tax returns.

Factors that May Impact our Future Financial Results

Our revenues are highly correlated to the level and relative mix of our AUM, as well as the fee rate associated with our ETFs. While our AUM has increased on an annual basis, we have experienced fluctuations on a quarterly basis due to changes in net inflows and market movement.

A significant portion of our AUM is invested in securities issued outside of the U.S. Therefore, our AUM and revenues are affected by movements in global capital market levels and the strengthening or weakening of the U.S. dollar against other currencies. As the chart below reflects, as of December 31, 2015, 62% of our U.S. AUM was concentrated in two products with similar strategies – HEDJ, our European equity ETF which hedges the Euro, and DXJ, our Japanese equity ETF which hedges the Yen. The strengthening of the Euro or Yen against the U.S. dollar, or the decline in European or Japanese equity markets, may have an adverse effect on our results.

36

Table of Contents

Another factor impacting our revenues is the fees associated with our ETFs. Our overall average fee rate is affected by the mix of flows into our ETFs. With a significant portion of our AUM invested in securities issued outside of the U.S., favorable market sentiment toward international equities (particularly during a time when the U.S. dollar is strengthening) is likely to have a positive effect on our overall revenues and conversely unfavorable market sentiment is likely to have a negative impact.

In addition, we currently compete within the ETF market against several large ETF sponsors, many smaller sponsors, as well as new entrants to the marketplace, and will compete against large asset management companies who have recently launched or announced intentions to launch ETF products. However, it is our belief that our ability to gather inflows into our ETFs, coupled with general stock market trends, will have the greatest impact on our business.

We have and will continue to strategically invest in our business in order to continue and accelerate our growth. We expect our investment in strategic growth initiatives to range from $12.0 to $16.0 million in 2016. These initiatives include:

The components of our strategic growth initiatives may increase or decrease from our planned estimates depending on the nature of the growth initiatives and market conditions.

Seasonality

We believe seasonal fluctuations in the asset management industry are common. However, since we began our operations, we believe these seasonal trends may have been masked by the unprecedented volatility in the global equity markets. Therefore, period to period comparisons of ours or the industry’s net inflows may not be meaningful or indicative of results in future periods.

Year Ended December 31, 2015 Compared to Year Ended December 31, 2014

Overview

Our U.S. listed AUM increased 31.5% from $39.3 billion at the end of 2014 to $51.6 billion at the end of 2015 primarily due to $16.9 billion of net inflows slightly offset by market depreciation. We reported pre-tax income of $137.2 million in 2015, an increase of 86.5% from 2014 primarily due to higher revenues, and we reported net income of $80.1 million in 2015 compared to $61.1 million in 2014.

Revenues

Advisory fees

Advisory fees revenues increased 63.0% from $182.8 million in 2014 to $297.9 million in 2015. This increase was primarily due to higher average asset balances due to our level of net inflows. The average U.S. advisory fee earned increased from 0.52% in 2014 to 0.53% in 2015 due to inflows into our higher fee ETFs.

Other income

Other income increased 5.5% from 2014 to 2015. This increase was primarily due to higher interest income from our growing cash balances and higher index licensing fees partly offset by losses on foreign currencies.

Compensation and benefits

This increase was primarily due to higher accrued incentive compensation due to our record inflow levels, increased headcount related expenses to support our growth and higher stock-based compensation due to equity awards granted to our employees as part of 2014 compensation. Our U.S. headcount was 101 and our non-U.S. headcount was 23 at the end of 2014 compared to a U.S. headcount of 137 and a non-U.S. headcount of 40 at the end of 2015.

Fund management and administration

Fund management and administration expense increased 24.4% from $34.4 million in 2014 to $42.8 million in 2015. This increase was primarily due to costs associated with higher average U.S. listed AUM; printing and mailing fees as a result of additional holders of our U.S. listed ETFs; and other costs associated with additional ETFs. We had 86 U.S. listed ETFs at the end of 2015. Lastly, we incurred higher costs for our non-U.S. listed ETFs as a result of new ETFs launched or cross listed in Europe.

Marketing and advertising

Marketing and advertising expense increased 16.1% from $11.5 million in 2014 to $13.4 million in 2015 primarily due to higher levels of advertising related activities to support our growth.

Sales and business development

Sales and business development expense increased 47.7% from $6.2 million in 2014 to $9.2 million in 2015 primarily due to higher levels of spending for sales and product development related initiatives.

Professional and consulting fees

Professional and consulting fees decreased 6.7% from $7.6 million in 2014 to $7.1 million in 2015. This decrease was primarily due to lower fees for strategic consulting services, and advisory costs associated with our acquisition of Boost in 2014, partly offset by higher recruiting fees as part of our sales force expansion plan.

Occupancy, communications and equipment

Occupancy, communications and equipment expense increased 20.2% from $3.6 million in 2014 to $4.3 million in 2015 primarily due to equipment purchases as part of our technology enhancements.

Depreciation and amortization

Depreciation and amortization expense increased 22.5% from $0.8 million in 2014 to $1.0 million in 2015 primarily due to amortization of leasehold improvements to our office space.

Third party sharing arrangements

Third party sharing arrangements expense increased 311.3% from $0.6 million in 2014 to $2.4 million in 2015 primarily due to higher fees to our third party marketing agent in Latin America as well as fees we pay to list our ETFs on a third party platform.

Acquisition contingent payment

Acquisition contingent payment expense was $2.2 million in 2015. This expense represents the change in the estimated fair value of the buyout obligation we have to the former shareholders of our European ETP business, which we acquired in April 2014. The buyout obligation is based on a formula that takes into account the AUM in the business, its profitability levels and the trading multiple of WETF.

Other

Other expenses increased 36.6% from $4.5 million in 2014 to $6.2 million in 2015 due to higher general and administrative expenses.

Income tax expense

Income tax expense was $57.1 million in 2015. The effective tax rate on our U.S. listed ETF business was 38.9% and our overall effective tax rate was 42.5% due to the non-deductibility of losses in our European ETP business.

Table of Contents

Our U.S. listed AUM increased 12.6% from $34.9 billion at the end of 2013 to $39.3 billion at the end of 2014 primarily due to $5.1 billion of net inflows slightly offset by market depreciation. We reported pre-tax income of $73.5 million in 2014, an increase of 42.7% from 2013 primarily due to higher revenues, and we reported net income of $61.1 million in 2014 compared to $51.5 million in 2013.

Revenues

Advisory fees

Advisory fees revenues increased 23.0% from $148.6 million in 2013 to $182.8 million in 2014. This increase was primarily due to higher average asset balances due to our level of net inflows. The average fee earned remained unchanged at 0.52% from 2013.

Other income

Other income increased 8.2% from 2013 to 2014. This increase was primarily due to higher interest income from our growing cash balances and realized gains on foreign currencies that we hold partly offset by lower index licensing fees.
