Amyris, Inc. (Nasdaq: AMRS) ("Amyris"), a leading synthetic biotechnology company accelerating the world to sustainable consumption through its Lab-to-Market^TM operating platform, today announced that it has priced $600.0 million aggregate principal amount of 1.50% convertible senior notes due 2026 (the "notes"). The size of the offering was increased from the previously announced $400.0 million in aggregate principal amount. The notes are to be offered and sold 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 "Act"). Amyris also granted the initial purchasers of the notes an option to purchase, within a 13-day period from, and including the date on which the notes are first issued, up to an additional $90.0 million aggregate principal amount of notes. The sale is expected to close on November 15, 2021, subject to customary closing conditions.

The notes will be senior, unsecured obligations of Amyris. The notes will bear cash interest at an annual rate of 1.50%, payable semiannually in arrears on May 15 and November 15 of each year, beginning on May 15, 2022.

The notes will mature on November 15, 2026, unless earlier converted, redeemed or repurchased in accordance with the terms of the notes. Prior to 5:00 p.m., New York City time, on the business day immediately preceding June 15, 2026, the notes will be convertible at the option of holders only upon satisfaction of certain conditions and during certain periods, and thereafter, the notes will be convertible at the option of holders at any time until 5:00 p.m., New York City time, on the second scheduled trading day immediately preceding the maturity date, regardless of whether such conditions have been met. Upon conversion, the notes may be settled in shares of Amyris' common stock (the "common stock"), cash or a combination of cash and shares of common stock, at the election of Amyris.

The notes will have an initial conversion rate of 93.0579 shares of common stock per $1,000 principal amount of notes (which is subject to adjustment in certain circumstances). This is equivalent to an initial conversion price of approximately $10.75 per share. The initial conversion price represents a premium of approximately 35% to the $7.96 per share closing price of the common stock on The Nasdaq Global Select Market on November 9, 2021.

Holders of the notes will have the right to require Amyris to repurchase for cash all or a portion of their notes at 100% of their principal amount, plus any accrued and unpaid interest, upon the occurrence of a fundamental change (as defined in the indenture relating to the notes). Amyris will also be required, in certain circumstances, to increase the conversion rate for holders who convert their notes in connection with certain fundamental changes prior to the maturity date or convert their notes called (or deemed called) for redemption during the related redemption period, as the case may be. The notes will be redeemable, in whole or in part, for cash at Amyris' option at any time, and from time to time, on or after November 20, 2024, but only if the last reported sale price per share of Amyris' common stock exceeds 130% of the conversion price for a specified period of time.

Amyris estimates that the net proceeds from the offering will be approximately $583.0 million (or approximately $670.5 million if the initial purchasers exercise their option to purchase additional notes in full), after deducting the initial purchasers' discount and estimated offering expenses payable by Amyris. Amyris intends to use $70.5 million of the net proceeds to pay the cost of the capped call transactions described below and $51.0 million of the net proceeds to repay certain existing senior debt instruments.

Amyris intends to use the remaining net proceeds for general corporate purposes, which may include, among other things, acquiring complementary products, technologies, intellectual property or businesses.

In connection with the pricing of the notes, Amyris entered into capped call transactions with certain of the initial purchasers or their respective affiliates and other financial institutions (the "option counterparties"). The capped call transactions are expected generally to reduce the potential dilution to the common stock upon any conversion of the notes and/or offset any cash payments Amyris is required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap.

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

In addition, the option counterparties and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to the common stock and/or purchasing or selling the common stock 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 and may do so following any repurchase of notes by Amyris on any fundamental change repurchase date or otherwise). This activity could also cause or avoid an increase or a decrease in the market price of the common stock or the notes, which could affect the holder's 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 number of shares and the value of the consideration that the holder would receive upon conversion of the notes.

If the initial purchasers exercise their option to purchase additional notes, Amyris expects to use the resulting additional proceeds of the sale of the additional notes to pay the cost of entering into the additional capped call transactions, for the repayment of existing senior debt instruments and for general corporate purposes, which may include, among other things, acquiring complementary products, technologies, intellectual property or businesses.

This announcement is neither an offer to sell nor a solicitation of an offer to buy any of these securities (including the shares of the 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. Any offers of the notes will be made only by means of a private offering memorandum.

The notes and any shares of the common stock issuable upon conversion of the notes have not been registered under the Act, 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.
