GI Dynamics Completes Initial Closing of a $10 Million Series A Preferred Stock Financing from Crystal Amber

BOSTON — September 10, 2020 GI Dynamics® Inc. (‘GI Dynamics” or the “Company”), a medical device company that is developing EndoBarrier® for patients with type 2 diabetes and obesity, is pleased to announce the initial closing of its private placement offering of Series A Preferred Stock led by Crystal Amber Fund Limited (“Crystal Amber”), the Company’s majority stockholder.

Sale of up to $10 million of Series A Preferred Stock

The Company conducted a Special Meeting of Stockholders on September 3, 2020 at which the proposals were approved to increase the number of authorized shares of common stock to 280 million shares, increase the number of authorized shares of preferred stock to 118 million shares, and to establish the terms of the Series A Preferred Stock, among other proposals that were also approved (see the Company’s Current Report on Form 8-K to be filed with the U.S. Securities and Exchange Commission on 10 September 2020 for details related to the Special Meeting of Stockholders).

The Company filed an Amended and Restated Certificate of Incorporation with the State of Delaware and completed the initial closing of the Crystal Amber led $10 million financing on September 4, 2020. The initial closing included the conversion of $1.25 million in outstanding convertible note principal into Series A Preferred Stock and the sale of $3.75 million of additional Series A Preferred Stock. The Company has issued 60,085,583 shares of Series A Preferred Stock to Crystal Amber.

As part of the financing terms, a Note Exchange and Warrant Cancellation Agreement wherein the warrant issued to Crystal Amber on January 13, 2020 was cancelled and the unsecured convertible promissory note issued to Crystal Amber in August 2019 was cancelled and exchanged for a new unsecured convertible promissory note (the “2020 Note”) for a principal amount of approximately $4.9 million. The 2020 Note earns annually compounded interest at a rate of 5% per annum and the maturity date is June 30, 2022.  At Crystal Amber’s sole discretion and at any time prior to June 30, 2022, the 2020 Note can be optionally converted into shares of common stock at a price equal to 200 percent of the initial purchase price of the Series A Preferred Stock.

The second closing of the financing is anticipated to include the sale of an additional $5 million of Series A Preferred Stock for the same price as the first closing and will occur on or before October 31, 2020. Crystal Amber has agreed to purchase any portion of the $5 million of shares not purchased by other investors.

Additionally, at the Special Meeting of Stockholders, the stockholders approved the Company’s 2020 Employee, Director and Consultant Equity Incentive Plan to provide for the issuance of equity awards reflecting up to 41,710,968 of shares of common stock to enable the Company to recruit and retain highly qualified employees, directors and consultants; provide them with an incentive for productivity; and provide them with an opportunity to share in the growth and value of the Company.

The funds raised in the financing are intended to be used for operations and to support the strategic priorities of the Company, which include attaining a CE mark for EndoBarrier, initiation of the I-STEP trial in India and resumption of the STEP-1 pivotal trial in the United States, pending the removal of COVID-19 related restrictions.

“We appreciate the ongoing support of Crystal Amber and look forward to continued achievements across our operations,” said Scott Schorer, GI Dynamics president and chief executive officer. “We are focused on attaining a CE Mark for EndoBarrier, continuing enrollment in the STEP-1 pivotal trial (US) and maintaining the care for patients already enrolled, gaining approval to initiate enrollment in the I-STEP clinical trial with Apollo Sugar (India), and continuing to work with leading clinicians around the world to develop further EndoBarrier clinical data.”
