Item 8.01. Other Events.

On August 11, 2025, WisdomTree, Inc. (the “Company”) issued a press release announcing that it had commenced a private offering, subject to market conditions and other factors, of $400 million aggregate principal amount of convertible senior notes due 2030 (the “Notes”) to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference. Neither this Current Report on Form 8-K nor the press release constitutes an offer to sell, or the solicitation of an offer to buy, the Notes or the shares of the Company’s common stock, if any, issuable upon conversion of the Notes.

The Company intends to use $275.0 million of the net proceeds from the offering of the Notes to pay the closing consideration for its previously announced acquisition of Ceres Partners, LLC (the “Acquisition”). The Company also intends to use a portion of the net proceeds from the offering to repurchase up to all $25.8 million in aggregate principal amount of its remaining outstanding 5.75% convertible senior notes due 2028, approximately $80.0 million of the net proceeds from the offering to repurchase shares of the Company’s common stock from certain purchasers of the Notes, and the remainder of the net proceeds from the offering, if any, for working capital and other general corporate purposes, which may include the repayment of indebtedness, including under its 3.25% convertible senior notes due 2026 and its 3.25% convertible senior notes due 2029. If the Acquisition is not consummated, the Company intends to use the proceeds it would have otherwise used to finance the Acquisition for general corporate purposes as described above. 

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements that are based on the Company’s management’s beliefs and assumptions and on information currently available to management. These statements may include statements relating to the Acquisition. Although the Company believes that the expectations reflected in these forward-looking statements are reasonable, these statements relate to future events or the Company’s future financial performance, and involve known and unknown risks, uncertainties and other factors that may cause 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 the Company’s 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 the Company’s 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 Current Report on Form 8-K completely and with the understanding that the Company’s 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 Current Report on Form 8-K may include statements about the proposed terms of the Notes, the size of the Notes offering, the expected use of the proceeds from the sale of the Notes, (including to finance the Acquisition), the consummation of the Acquisition and other statements contained in this Current Report on Form 8-K that are not historical facts. Forward-looking statements are subject to many risks and uncertainties, including without limitation, risks related to or associated with whether the Company will consummate the offering of the Notes on the expected terms, or at all, which could differ or change based upon market conditions or other reasons, and the other risks set forth under the caption “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, and in subsequent reports filed with or furnished to the Securities and Exchange Commission.
