Forward Looking Statements
This presentation contains forward-looking statements that are based on our management’s belief and assumptions and on information currently available to our management. Although we believe that the expectations reflected in these forward-looking statements are reasonable, these statements relate to future events or our future financial performance, and involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “continue” or the negative of these terms or other comparable terminology. These statements are only predictions. You should not place undue reliance on forward-looking statements because they involve known and unknown risks, uncertainties and other factors, which are, in some cases, beyond our control and which could materially affect results. Factors that may cause actual results to differ materially from current expectations include, among other things, the risks described below. If one or more of these or other risks or uncertainties occur, or if our underlying assumptions prove to be incorrect, actual events or results may vary significantly from those implied or projected by the forward-looking statements. No forward-looking statement is a guarantee of future performance. You should read this presentation completely and with the understanding that our actual future results may be materially different from any future results expressed or implied by these forward-looking statements.
In particular, forward-looking statements in this presentation may include statements about: anticipated trends, conditions and investor sentiment in the global markets and exchange-traded products (“ETPs”); anticipated levels of inflows into and outflows out of our ETPs; our ability to deliver favorable rates of return to investors; our ability to develop new products and services; our ability to maintain current vendors or find new vendors to provide services to us at favorable costs; our ability to successfully expand our business into non-U.S. markets; competition in our business; and the effect of laws and regulations that apply to our business.
Our business is subject to many risks and uncertainties, including without limitation:
Net outflows in our two largest ETFs – the WisdomTree Europe Hedged Equity Fund and the WisdomTree Japan Hedged Equity Fund – have had, and in the future could continue to have, a negative impact on our revenues.
Over the last few years, we have expanded our business into Europe, Japan and Canada. This expansion subjects us to increased operational, regulatory, financial and other risks.
The ETFS acquisition is significant in size relative to our assets and operations and may result in significant changes in our business. Our failure to integrate and manage ETFS successfully could materially and adversely affect our business, results of operations and financial condition.
Declining prices of securities, precious metals and other commodities can adversely affect our business by reducing the market value of the assets we manage or causing customers to sell their fund shares and trigger redemptions.
Fluctuations in the amount and mix of our AUM, whether caused by disruptions in the financial markets or otherwise, may negatively impact revenues and operating margins, and may impede our ability to refinance our debt upon maturity, increase the cost of borrowing or result in our debt being called prior to maturity.
We derive a substantial portion of our revenues from a limited number of products, and as a result, our operating results are particularly exposed to the performance of these products and our ability to maintain the AUM of these products, as well as investor sentiment toward investing in the products’ strategies and market-specific and political and economic risk.
Much of our AUM is held in our U.S. listed 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 ETPs and ETFs have a limited track record, and poor investment performance could cause our revenues to decline.
We depend on third parties to provide many critical services to operate our business and our ETPs. The failure of key vendors to adequately provide such services could materially affect our operating business and harm our customers.
Other factors, such as general economic conditions, including currency exchange rate fluctuations, also may have an effect on the results of our operations. For a more complete description of the risks noted above and other risks that could cause our actual results to differ from our current expectations, please see the section entitled “Risk Factors” in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017.
The forward-looking statements in this presentation represent our views as of the date of this presentation. We anticipate that subsequent events and developments may cause our views to change. However, while we may elect to update these forward-looking statements at some point in the future, we have no current intention of doing so except to the extent required by applicable law. Therefore, these forward-looking statements do not represent our views as of any date other than the date of this presentation.

Overview
+ On April 11, 2018, we acquired the European exchange-traded commodity, currency and short-and-leveraged business (“ETFS”) from ETF Securities Limited (“ETF Securities”), which includes $17.6 billion of assets under management (“AUM”) as of April 10, 2018.
+ The acquisition elevates us to the 9th largest ETP sponsor globally and the largest global independent ETP provider based on AUM, with significant scale and presence in the U.S. and Europe, the two largest ETP markets.
+ The purchase price was $523 million consisting of $253 million of cash and 30 million shares of WisdomTree common stock, based on the market close on April 10, 2018. The cash portion of the purchase price was funded with $53 million of balance sheet cash and $200 million from a newly raised term loan.
+ Given the size of the transaction, we filed proforma financial statements reflecting what the combined financial statements of the company would look like had the acquisition occurred in 2017. This disclosure is required by the SEC.
+ The proforma financials do not completely reflect what we believe will be the operating results of ETFS as it does not account for synergies we believe we can achieve through the acquisition and due to GAAP requirements, reflected higher expenses of the legacy ETF Securities business which we did not acquire.
+ Therefore, the purpose of this presentation is to provide:
? additional information on key transactions related to our acquisition of ETFS
a description of changes we are making to our financial reporting and operating data disclosures to better reflect the global scale of our business guidance for our international business segment, which will now include ETFS
Additional information on taxes

Key Items Post Transaction
Below are key items associated with our acquisition of ETFS that we believe investors should understand to better analyze our business going forward:
+ Contractual gold payments
+ Term loan and revolving credit facility
+ Issuance of preferred stock
+ Preliminary purchase price allocation
+ Taxes
4

Contractual Gold Payments—Deferred Consideration
+ In 2008, ETF Securities acquired Gold Bullion Securities (“GBS”) a gold-backed ETC owned by Gold Bullion
Holdings (“GBH”), a company owned two-thirds by the World Gold Council and one-third by Graham Tuckwell.
+ The acquisition did not involve any up-front payment. Instead, ETF Securities agreed to pay GBH’s shareholders
9,500 ounces of gold per year until March 2058, which is then reduced to 6,333 ounces into perpetuity.
+ Our acquisition of ETFS did not terminate this contractual gold payment obligation. Instead, we assumed this obligation and entered into a new agreement with ETF Securities which provides for the same contractual gold payment in order for ETF Securities to satisfy its obligation to GBH. We refer to this payment to ETF Securities as
“contractual gold payments” on our income statement.
+ The contractual gold payment is paid from the advisory fee income we earn for managing the gold-backed ETCs. The payment can be reduced if our advisory fee income from the gold ETCs is not enough to cover this obligation. However, any unpaid amounts accrue and are payable when the advisory fee income is enough to satisfy the obligation. There is no recourse back to WisdomTree for any unpaid amounts.
+ 9,500 ounces of gold is currently worth $12.5 million based on the price of gold as of May 9, 2018. This amount will be recorded as an operating expense titled “contractual gold payments” on our revised income statement
(see page 9).
+ We also recorded the fair value of this obligation on our balance sheet as “deferred consideration” since it arises from ETF Securities’ acquisition of GBS. We determined the present value of this obligation as $172.7 million based on the future price of gold. Every quarter, we will re-measure the fair value of this liability. The change to the fair value, which will be predominantly driven by the price of gold, will flow through our income statement as a non-operating item titled “revaluation of deferred consideration.”

Term Loan and Revolving Credit Facility
We entered into a $200 million term loan and $50 million revolving credit facility. We have not used the revolving credit facility. Key terms of the term loan are as follows:
+ Rate: LIBOr + 1.75

Preferred Stock
WisdomTree issued common and preferred stock as part of the ETFS acquisition. Key terms for the stock portion of the transaction consideration are as follows:
+ 15.25 million shares of common stock
+ 14,750 non-voting preferred shares convertible into 14.75 million shares of common stock
+ The preferred shares have the same priority for dividends, distributions and payments as WisdomTree’s common stock; however, the preferred shares have no voting rights and are not transferable.
+ ETF Securities has a maximum 9.99% voting interest
+ There are lockups and standstill agreements in place. The lockups are as follows:
~ 3 months post closing until July 11, 2018 – 10 million shares
~9 months post closing until January 7, 2019 – 10 million shares
~ 15 months post closing until July 6, 2019 – 10 million shares
+ A portion of the preferred shares are treated as mezzanine equity on the balance sheet between Liabilities and Equity as they may redeemed by ETF Securities under certain circumstances.
7

Preliminary Purchase Price Allocation
+ WisdomTree engaged a valuation consultant to allocate the purchase price across the assets acquired from ETF Securities. Preliminary allocation of the purchase price using the proforma financial statements as of December 31, 2017 is as follows:
($ millions)
Cash
$253.0
Shares (30m x $9.00)
270.0
