Coupa Software (COUP) 8-K Entry into a Material Definitive Agreement

Exhibit 99.4

Coupa Announces Closing of $700 Million Convertible Senior Notes Due 2025 and

Full Exercise of Initial Purchasers’ $105 Million Option to Purchase Additional

Notes

SAN MATEO, Calif., June 11, 2019– Coupa Software (NASDAQ: COUP) today announced that it has closed its offering of convertible senior notes due 2025 (the “notes”) for gross proceeds of $805.0 million. The proceeds include the full exercise of the $105 million option to purchase additional notes granted by Coupa to the initial purchasers. The notes were sold to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended.

The notes are senior, unsecured obligations of Coupa, and interest is payable semi-annually in cash at a rate of 0.125% per annum on June 15 and December 15 of each year, beginning on December 15, 2019. The notes will mature on June 15, 2025 unless redeemed, repurchased or converted prior to such date. Prior to March 15, 2025, the notes are convertible at the option of holders during certain periods, upon satisfaction of certain conditions. Thereafter, the notes are convertible at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, the notes may be settled in shares of Coupa common stock, cash or a combination of cash and shares of Coupa common stock, at Coupa’s election.

The notes have an initial conversion rate of 6.2658 shares of common stock per $1,000 principal amount of notes (subject to customary adjustments in certain circumstances). This represents an initial effective conversion price of approximately $159.60 per share. The initial conversion price of the notes represents a premium of approximately 35% to the $118.22 per share closing price of Coupa common stock on June 6, 2019.

Coupa estimates that the net proceeds from the offering, given the initial purchasers’ exercise in full of their option to purchase additional notes, are approximately $786.2 million after deducting the initial purchasers’ discount and estimated offering expenses payable by Coupa. Coupa used approximately $118.7 million of the net proceeds to pay the cost of the capped call transactions described below. Coupa intends to use the remainder of the net proceeds from this offering for general corporate purposes, potential acquisitions and strategic transactions. Coupa has no agreements or understandings with respect to any material acquisitions or strategic transactions at this time.

Coupa may redeem all or any portion of the notes, at its option, on or after June 20, 2022, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon, if the last reported sale price of Coupa’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which Coupa provides written notice of redemption.

Holders of notes may require Coupa to repurchase their notes upon the occurrence of certain events that constitute a fundamental change under the indenture governing the notes at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the date of repurchase. In connection with certain corporate events or if Coupa issues a notice of redemption, it will, under certain circumstances, increase the conversion rate for holders who elect to convert their notes in connection with such corporate event or during the relevant redemption period.

In connection with the pricing of the notes, Coupa has entered into privately negotiated capped call transactions with certain of the initial purchasers of the notes and/or their respective affiliates (the “capped call counterparties”). The capped call transactions initially cover, subject to customary anti-dilution adjustments, the number of shares of Coupa common stock that initially underlie the notes, including the notes purchased pursuant to the option to purchase additional notes. The cap price of the capped call transactions is initially $295.55 per share of Coupa’s common stock, representing a premium of 150% above the last reported sale price of $118.22 per share of Coupa’s common stock on June 6, 2019, 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 Coupa’s common stock upon conversion of the notes and/or offset the potential cash payments that Coupa 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 Coupa that they and/or their respective affiliates expect to enter into various derivative transactions with respect to Coupa common stock and/or purchase Coupa 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 Coupa 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 Coupa common stock and/or purchasing or selling Coupa 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 Coupa 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 notes, it could affect the amount and value of the consideration that noteholders will receive upon conversion of such notes.

This announcement is neither an offer to sell nor a solicitation of an offer to buy any of these securities (including the shares of Coupa common stock, if any, into which the notes are convertible) and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.

The notes and any shares of common stock issuable upon conversion of the notes have not been registered under the Securities Act of 1933, as amended, or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirements.
