On May 18, 2018, Alteryx, Inc. (“Alteryx”) completed its previously announced sale of $200.0 million aggregate principal amount of 0.50% Convertible Senior Notes due 2023 (the “Notes”) to qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act of 1933, as amended.

Indenture

The Notes were issued pursuant to an Indenture, dated as of May 18, 2018 (the “Indenture”), between Alteryx and U.S. Bank National Association, as trustee. The Notes are senior unsecured obligations of Alteryx. The Notes will bear interest of 0.50% per year payable semi-annually in arrears. The Notes mature on June 1, 2023 unless repurchased or converted in accordance with their terms prior to such date.

Alteryx may not redeem the Notes prior to the maturity date, and no sinking fund is provided for the Notes.

The Indenture includes customary terms and covenants, including certain events of default after which the Notes may be declared due and payable immediately and sets forth certain types of bankruptcy or insolvency events of default involving Alteryx after which the Notes become automatically due and payable. The following events are considered “events of default,” which may result in acceleration of the maturity of the Notes:

and in the cases of clauses (i) and (ii), such acceleration shall not have been rescinded or annulled or such failure to pay or default shall not have been cured or waived, or such indebtedness is not paid or discharged, as the case may be, within 30 days after written notice to us by the trustee or to us and the trustee by holders of at least 25% in aggregate principal amount of notes then outstanding in accordance with the indenture;

The Notes are convertible into cash, shares of Class A Common Stock or a combination thereof, at Alteryx’s election, at an initial conversion rate of 22.5572 shares of Class A Common Stock per $1,000 principal amount of the Notes, which is equal to an initial conversion price of approximately $44.33 per share of Class A Common Stock subject to adjustment. Prior to the close of business on the business day immediately preceding March 1, 2023, such conversion is subject to the satisfaction of certain conditions set forth below.

Holders of the Notes who convert their Notes in connection with a make-whole fundamental change (as defined in the Indenture) are, under certain circumstances, entitled to an increase in the conversion rate. Additionally, in the event of a fundamental change (as defined in the Indenture), holders of the Notes may require Alteryx to repurchase all or a portion of their Notes at a price equal to 100% of the principal amount of Notes, plus any accrued and unpaid special interest to, but excluding, the repurchase date.

Holders of the Notes may convert all or a portion of their Notes prior to the close of business on the business day immediately preceding March 1, 2023, in multiples of $1,000 principal amount, only under the following circumstances:

A copy of the Indenture is attached hereto as Exhibit 4.1 and is incorporated herein by reference. The description of the Notes contained in this Current Report on Form 8-K (this “Form 8-K”) does not purport to be complete and is qualified in its entirety by reference to Exhibit 4.1.

Capped Call Transactions

On May 15, 2018, in connection with the pricing of the Notes, Alteryx entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with each of JPMorgan Chase Bank, National Association, London Branch, Bank of America, N.A., and RBC Capital Markets, LLC (the “Capped Call Counterparties”). The Capped Call Transactions initially cover, subject to customary anti-dilution adjustments, the number of shares of Class A Common Stock that initially underlie the Notes (and are likely to so do during any observation period related to a conversion of the notes or following any repurchase of notes by us on any fundamental change or otherwise). The cap price of the Capped Call Transactions is initially $62.22 per share of Class A Common Stock, representing a premium of 100% above the last reported sale price of $31.11 per share of Class A Common Stock on May 15, 2018, and is subject to certain adjustments under the terms of the Capped Call Transactions. The Capped Call Transactions are expected generally to reduce or offset potential dilution to holders of Common Stock upon conversion of the Notes and/or offset the potential cash payments that Alteryx could be required to make in excess of the principal amount of any converted Notes upon conversion thereof, with such reduction and/or offset subject to a cap based on the cap price.

In connection with establishing their initial hedge of the Capped Call Transactions, the Capped Call Counterparties have advised Alteryx that they and/or their respective affiliates expect to enter into various derivative transactions with respect to Class A Common Stock and/or purchase Class A Common Stock concurrently with, or shortly after, the pricing of the Notes. This activity could increase (or reduce the size of any decrease in) the market price of Class A Common Stock or the Notes concurrently with, or shortly after, the pricing of the Notes.

In addition, the Capped Call Counterparties and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Class A Common Stock and/or purchasing or selling Class A Common Stock in secondary market transactions following the pricing of the Notes and prior to the maturity of the

Notes. This activity could decrease (or avoid an increase) in the market price of Class A Common Stock or the Notes, which could affect noteholders’ ability to convert the Notes and, to the extent the activity occurs during any observation period related to a conversion of the Notes, it could affect the amount and value of the consideration that noteholders will receive upon conversion of such Notes.

The Capped Call Transactions are separate transactions entered into by Alteryx with the Capped Call Counterparties, are not part of the terms of the Notes, and will not affect any holder’s rights under the Notes. Holders of the Notes will not have any rights with respect to the Capped Call Transactions.

The form of the Capped Call Transaction confirmation (the “Base Capped Call Confirmation”) is attached hereto as Exhibits 99.1 and is incorporated by reference. The description of the Base Capped Call Confirmation contained in this Current Report on Form 8-K does not purport to be complete and is qualified in its entirety by reference to Exhibit 99.1.

The information set forth above in Item 1.01 of this Form 8-K is incorporated by reference into this Item 2.03.

The information set forth above in Item 1.01 of this Form 8-K is incorporated by reference into this Item 3.02.

On May 18, 2018, Alteryx issued a press release announcing the closing of its offering of the Notes. A copy of the press release is attached as Exhibit 99.2 and incorporated herein by reference.
