Exhibit 99.1

Danimer Scientific Prices Upsized

$200 Million Convertible Senior Notes Offering

BAINBRIDGE, GA – December 16, 2021 – Danimer Scientific, Inc. (NYSE: DNMR) (“Danimer” or the “Company”), a leading next generation bioplastics company focused on the development and production of biodegradable materials, announced today the pricing of its offering of $200,000,000 aggregate principal amount of 3.250% convertible senior notes due 2026 (the “notes”) in a private offering to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The offering size was increased from the previously announced offering size of $175,000,000 aggregate principal amount of notes. The issuance and sale of the notes are scheduled to settle on December 21, 2021, subject to customary closing conditions. Danimer also granted the initial purchasers of the notes an option to purchase, for settlement within a period of 13 days from, and including, the date the notes are first issued, up to an additional $40,000,000 aggregate principal amount of notes.

The notes will be senior, unsecured obligations of Danimer and will accrue interest at a rate of 3.250% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2022. The notes will mature on December 15, 2026, unless earlier repurchased, redeemed or converted. Before June 15, 2026, noteholders will have the right to convert their notes only upon the occurrence of certain events. From and after June 15, 2026, noteholders may convert their notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. Danimer will settle conversions by paying or delivering, as applicable, cash, shares of its Class A common stock, par value $0.0001 per share (the “common stock”), or a combination of cash and shares of its common stock, at Danimer’s election. The initial conversion rate is 92.7085 shares of common stock per $1,000 principal amount of notes, which represents an initial conversion price of approximately $10.79 per share of common stock. The initial conversion price represents a premium of approximately 27.5% over the last reported sale price of $8.46 per share of Danimer’s common stock on December 16, 2021. The conversion rate and conversion price will be subject to adjustment upon the occurrence of certain events.

The notes will be redeemable, in whole or in part (subject to certain limitations), for cash at Danimer’s option at any time, and from time to time, on or after December 20, 2024 and on or before the 40th scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of Danimer’s common stock exceeds 130% of the conversion price for a specified period of time and certain liquidity conditions have been satisfied. The redemption price will be equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

If a “fundamental change” (as defined in the indenture for the notes, but which would include, without limitation, certain change of control transactions, such as certain mergers, sales of all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, or a person or group of persons acquiring beneficial ownership of a majority of the voting power of the Company’s common stock, the Company’s stockholders approving the liquidation or dissolution of the Company, or our common stock ceasing to be listed on the NYSE, The NASDAQ Capital Market, The NASDAQ Global Market or The NASDAQ Global Select Market) occurs, then, except as described in the indenture, noteholders may require Danimer to repurchase their notes for cash. The repurchase price will be equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

Danimer estimates that the net proceeds from the offering will be approximately $191.9 million (or approximately $230.7 million if the initial purchasers fully exercise their option to purchase additional notes), after deducting the initial purchasers’ discounts and commissions and estimated offering expenses. Danimer intends to use $29.2 million of the net proceeds to fund the cost of entering into the capped call transactions described below. Danimer intends to use the remainder of the net proceeds from the offering for general corporate purposes, including working capital and capital expenditures. If the initial purchasers exercise their option to purchase additional notes, then Danimer intends to use a portion of the additional net proceeds to fund the cost of entering into additional capped call transactions as described below.

In connection with the pricing of the notes, Danimer entered into privately negotiated capped call transactions with one or more of the initial purchasers or their affiliates and/or other financial institutions (the “option counterparties”). The capped call transactions will cover, subject to customary anti-dilution adjustments, the number of shares of Danimer’s common stock underlying the notes. If the initial purchasers exercise their option to purchase additional notes, Danimer expects to enter into additional capped call transactions with the option counterparties.

The cap price of the capped call transactions will initially be $16.92 per share, which represents a premium of 100% over the last reported sale price of Danimer’s common stock of $8.46 per share on December 16, 2021, and is subject to certain adjustments under the terms of the capped call transactions upon the occurrence of certain specified events, including without limitation certain specified change of control transactions or any acquisition or disposition by the Company for consideration in excess of 25% of our market capitalization at such time.

The capped call transactions are expected generally to reduce the potential dilution to Danimer’s common stock upon any conversion of the notes and/or offset any potential cash payments Danimer is required to make in excess of the principal amount of converted notes, as the case may be, upon conversion of the notes. If, however, the market price per share of Danimer’s common stock, as measured under the terms of the capped call transactions, exceeds the cap price of the capped call transactions, there would nevertheless be dilution and/or there would not be an offset of such potential cash payments, in each case, to the extent that such market price exceeds the cap price 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 Danimer’s common stock and/or purchase shares of Danimer’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 Danimer’s common stock or the notes at that time.

Danimer has been advised that, in addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Danimer’s common stock and/or purchasing or selling Danimer’s common stock or other securities of Danimer in secondary market transactions following the pricing of the notes and from time to time prior to the maturity of the notes (and are likely to do so following any conversion of the notes, any repurchase of the notes by Danimer on any fundamental change repurchase date, any redemption date or any other date on which the notes are retired by Danimer, in each case if Danimer exercises the relevant election to terminate the corresponding portion of the capped call transactions). This activity could also cause or avoid an increase or decrease in the market price of Danimer’s common stock or the notes, which could affect the ability of noteholders 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, if any, and value of the consideration that noteholders will receive upon conversion of the notes.

The notes will be offered only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act. The offer and sale of the notes and any shares of common stock issuable upon conversion of the notes have not been, and will not be, registered under the Securities Act or any other securities laws, and the notes and any such shares cannot be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and any other applicable securities laws. This press release does not constitute an offer to sell, or the solicitation of an offer to buy, the notes or any shares of common stock issuable upon conversion of the notes, nor will there be any sale of the notes or any such shares, in any state or other jurisdiction in which such offer, sale or solicitation would be unlawful.
