Tandem Diabetes Care Announces Pricing of $250.0 Million of Convertible Senior Notes Due 2025

Tandem Diabetes Care®, Inc. (NASDAQ: TNDM) ("Tandem" or, the "Company") announced today the pricing of $250.0 million aggregate principal amount of 1.50 percent Convertible Senior Notes due 2025 (the "Notes") in a private placement to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). Tandem also granted the initial purchasers of the Notes an option to purchase, within a 13-day period beginning on, and including, the date on which the Notes are first issued, up to an additional $37.5 million aggregate principal amount of Notes. The sale of the Notes is expected to close on May 15, 2020, subject to customary closing conditions.

The Notes will be senior unsecured obligations of Tandem, and will bear interest at a rate of 1.50 percent per year, payable semiannually in arrears on May 1 and November 1 of each year, beginning on November 1, 2020. The Notes will mature on May 1, 2025, unless earlier repurchased, redeemed, or converted in accordance with their terms prior to the maturity date. The Notes will be convertible at the option of the holders prior to the close of business on the business day immediately preceding November 1, 2024 only upon the satisfaction of certain conditions and during certain periods. Thereafter, the Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion of the Notes, Tandem will settle such conversion in cash, shares of Tandem’s common stock, or a combination of cash and shares of Tandem’s common stock, at Tandem’s election.

Tandem may not redeem the Notes prior to May 6, 2023. Tandem may redeem for cash all or any portion of the Notes, at its option, on or after May 6, 2023 if the last reported sale price of Tandem’s common stock has been at least 130 percent 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 Tandem provides notice of redemption at a redemption price equal to 100 percent of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

Upon the occurrence of certain events that constitute a fundamental change (as defined in the indenture governing the Notes), subject to certain conditions, holders of the Notes may require Tandem to repurchase for cash all or part of their Notes in principal amounts of $1,000 or an integral multiple thereof. The repurchase price will be equal to 100 percent of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding the fundamental change repurchase date. Under certain circumstances, Tandem will also be required to increase the conversion rate for holders who convert their Notes in connection with certain events, including certain fundamental change events occurring prior to the maturity date, or in connection with Tandem’s issuance of a notice of redemption.

The Notes will have an initial conversion rate of 8.8836 shares of Tandem’s common stock per $1,000 principal amount of Notes, which is subject to adjustment in certain circumstances. This conversion rate is equivalent to an initial conversion price of approximately $112.57 per share of Tandem’s common stock. The initial conversion price represents a premium of approximately 30 percent to the $86.59 per share last reported sale price of Tandem’s common stock on the Nasdaq Global Market on May 12, 2020.

Tandem estimates that the net proceeds from the offering will be approximately $242.5 million (or approximately $278.9 million if the initial purchasers exercise their option to purchase additional Notes in full), after deducting the initial purchasers’ discounts and commissions and estimated offering expenses payable by Tandem. Tandem intends to use approximately $29.6 million of the net proceeds from the offering to pay the cost of the privately negotiated capped call transactions described below, and expects to use the remainder of the net proceeds from the offering for working capital and other general corporate purposes. If the initial purchasers exercise their option to purchase additional Notes in full, Tandem expects to use a portion of the net proceeds from such additional Notes to enter into additional capped call transactions.

The Notes and any shares of Tandem's common stock issuable upon conversion of the Notes have not been registered under the Securities Act or any state securities laws. Unless a subsequent sale is registered under the Securities Act, the Notes and shares of Tandem's common stock issuable upon conversion of the Notes may only be offered or sold in the United States in a transaction that is exempt from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.

This press release is not an offer to sell and is not soliciting an offer to buy any securities, nor will it constitute an offer, solicitation, or sale of the securities in any jurisdiction in which such offer, solicitation, or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction.

In connection with the pricing of the Notes, Tandem entered into privately negotiated capped call transactions with certain of the initial purchasers, and/or their respective affiliates and/or other financial institutions (collectively, the "option counterparties"). The capped call transactions cover, subject to customary anti-dilution adjustments, the number of shares of Tandem’s common stock that will initially underlie the Notes, assuming the initial purchasers do not exercise their option to purchase additional Notes. The capped call transactions are expected generally to reduce potential dilution to holders of Tandem’s common stock on any conversion of Notes and/or offset any cash payments Tandem is required to make in excess of the principal amount of any such converted Notes, as the case may be, with such reduction and/or offset subject to a cap based on the cap price. The cap price of the capped call transactions is initially $173.18 per share of Tandem’s common stock, representing a premium of 100 percent above the last reported sale price of $86.59 per share of Tandem’s common stock on May 12, 2020, and is subject to certain adjustments under the terms of the capped call transactions.

In connection with establishing their initial hedges of the capped call transactions, the option counterparties or their respective affiliates expect to enter into various derivative transactions with respect to Tandem’s common stock and/or purchase Tandem’s 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 Tandem’s common stock or the Notes at that time.

In addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Tandem’s common stock and/or purchasing or selling Tandem’s common stock or other securities of Tandem in secondary market transactions following the pricing of the Notes and prior to the maturity of the Notes (and are likely to do so during any observation period related to a conversion of Notes). This activity could also cause or avoid an increase or decrease in the market price of Tandem’s 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 number of shares and the value of the consideration that noteholders will receive upon conversion of such Notes.
