Item 7.01 Regulation FD Disclosure.

As previously disclosed, TerraVia Holdings, Inc. (the “Company”) is engaged in activities to restructure its 6.00% convertible senior subordinated notes due 2018 (the “2018 Notes”) and its 5.00% convertible senior subordinated notes due 2019 (the “2019 Notes”). Specifically, the Company is currently in negotiations with significant holders of the 2018 Notes and the 2019 Notes about a potential restructuring of the Company’s funded debt. The Company has retained Rothschild Inc. and Davis Polk & Wardwell LLP to advise on the potential restructuring. However, no agreements have been reached and any such negotiation may not lead to an agreement or a transaction to restructure the Company’s funded debt.

In April 2014, the Company issued $149.5 million aggregate principal amount of the 2019 Notes, of which $140.5 million in aggregate principal amount remained outstanding as of March 31, 2017. The next interest payment on the 2019 Notes is due April 3, 2017 (the next succeeding business day after the April 1 interest payment date). Pursuant to the indenture governing the 2019 Notes, the Company is entitled to a 30-day grace period in which to make the interest payment. The Company is exercising its right to use this grace period in consideration of debt restructuring activities, and will not make this interest payment on April 3, 2017. No “Event of Default” will be deemed to have occurred under the indenture unless the Company does not make the interest payment during the 30-day grace period.

In April 2016, Silicon Valley Bank (“SVB”) issued a standby letter of credit (“SVB SLOC”) in favor of Itaú Unibanco S.A. (“Itaú”) to support a bank guarantee issued by Itaú on behalf of the Company to the Brazilian Development Bank (“BNDES”) in connection with the loan agreement entered into in 2013 between BNDES and Solazyme Bunge Produtos Renováveis Ltda., the Company’s joint venture with Bunge Global Innovation, LLC. The SVB SLOC is supported by a loan and security agreement (the “Agreement”) the Company entered into with SVB in June 2016. The Company intends to work with SVB to either amend or terminate the Agreement. Should the Company and SVB terminate the Agreement, the Company expects it would replace the Agreement with a Bank Services Cash Pledge Agreement (the “Pledge Agreement”) between SVB and the Company to cash collateralize and secure the SVB SLOC. The currently outstanding SVB SLOC is expected to remain in place.

The foregoing contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 about the Company, including statements that involve risks and uncertainties concerning: ongoing activities to restructure the Company’s funded debt and the prospects of those activities being successful; the impact of any restructuring of the Company’s funded debt or the failure to do so; the Company’s intent not to make an interest payment on the 2019 Notes on the due date; the impact of such non-payment; the Company’s intent to amend or terminate the Agreement and/or enter into a Pledge Agreement; the Company’s expectation to cash collateralize the SVB SLOC if the Agreement is terminated; and the Company’s expectation that the SVB SLOC will remain in place. When used herein, the words “will”, “expects”, “intends” and other similar expressions and any other statements that are not historical facts are intended to identify those assertions as forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Any such statement may be influenced by a variety of factors, many of which are beyond the control of the Company, that could cause actual outcomes and results to be materially different from those projected, described, expressed or implied herein due to a number of risks and uncertainties.
