New Strategic Partnership Provides Funding to Support U.S. Growth Initiatives and Coronary Product Development, Opens New Pathway for Sales in Asia

REDWOOD CITY, CA / ACCESSWIRE / March 20, 2024 / Avinger, Inc. (Nasdaq:AVGR), a commercial-stage medical device company developing and marketing the first and only intravascular image-guided, catheter-based systems for diagnosis and treatment of vascular disease, today reported results for the fourth quarter and full year ended December 31, 2023.

Fourth Quarter and Recent Highlights

• Announced up to $15 million strategic financing and partnership agreement with Zylox-Tonbridge, a leading provider of neuro- and peripheral-vascular interventional solutions in China, with $7.5 million initial equity investment funded in March 2024
• Reported fourth quarter 2023 revenue of $1.9 million, a sequential increase of 5%, and gross margin of 20%
• Expanded sales team by more than 25% and deepened Avinger's presence in key Midwest, Texas and Florida markets
• Expanded full commercial launch of Tigereye ST, Avinger's most advanced image-guided peripheral CTO-crossing device, based on strong momentum in the fourth quarter
• Continued limited launch of the new Pantheris LV (large vessel) image-guided atherectomy device in anticipation of full commercial launch
• Advanced development of proprietary image-guided coronary CTO-crossing system, including completion of Phase 2 design selection and multiple rounds of animal and cadaver heart studies, with IDE submission anticipated in the third quarter of 2024

"We are excited to begin our strategic partnership with Zylox-Tonbridge, a dynamic leader in the peripheral interventional market in China," said Jeff Soinski, Avinger's President and CEO. "Not only does this partnership provide strategic equity funding to support our growth initiatives in the U.S. market and advance development of our first coronary product, it also opens a proven commercial channel for Avinger products to enter the robust and growing Greater China market. The strategic relationship provides the opportunity for Avinger to partner with Zylox-Tonbridge to develop a more cost-efficient manufacturing structure to support the growth of global sales and improve gross margin. It also allows Avinger to access certain of Zylox-Tonbridge's high-quality peripheral products for distribution in the U.S. and Germany, providing the opportunity for incremental revenue growth and increased sales productivity without significant R&D investment.

"Across our existing commercial portfolio, commercial launch activity for the Tigereye ST CTO-crossing catheter is showing exciting momentum in the marketplace, and we intend to build on this success with the full commercial launch of our Pantheris LV image-guided atherectomy system later this year. We have also seen good early signs of success with our sales team expansion efforts, growing the team by more than 25% since the end of the third quarter and strengthening our presence in key Midwest, Texas and Florida markets.

"We are excited about the development progress on our first coronary product application, including completion of Phase 2 design selection and now three animal studies and two cadaver heart studies with key opinion leader physicians at one of the nation's top clinical institutions. We anticipate filing an IDE application with the FDA in the third quarter of 2024 to allow for the initiation of a clinical study following approval. In entering the coronary space, we seek to offer a superior, simplified, and more predictable clinical outcome for crossing chronic total occlusions in the coronary arteries, a procedure that is currently characterized by complex, highly invasive procedures and uncertain outcomes. We believe that our proprietary image-guided approach has the potential to redefine this large and underserved market, while immediately accessing established reimbursement codes for coronary CTO-crossing and OCT-diagnostic imaging following clearance."

Fourth Quarter 2023 Financial Results

Total revenue was $1.9 million for the fourth quarter of 2023, compared with $1.8 million in the third quarter of 2023 and $2.0 million in the fourth quarter of 2022. The Company has expanded the sales force by more than 25% since the end of the third quarter to drive revenue growth in 2024.

Gross margin for the fourth quarter of 2023 was 20%, compared with 21% in the third quarter of 2023 and 34% in the fourth quarter of 2022. The change in gross margin primarily reflects lower production activity during the fourth quarter of 2023 as the Company seeks to optimize inventory levels and increased non-cash stock-based compensation expense. Operating expenses for the fourth quarter of 2023 were $5.0 million, compared with $4.4 million in the third quarter of 2023 and $4.5 million in the fourth quarter of 2022. The increase in operating expense is primarily related to the increase in sales headcount, corporate expense related to the Zylox-Tonbridge transaction, and non-cash stock-based compensation expense.

Net loss and comprehensive loss for the fourth quarter of 2023 was $5.0 million, compared with $4.5 million in the third quarter of 2023 and $4.2 million in the fourth quarter of 2022.

Adjusted EBITDA, as defined under non-GAAP financial measures in this press release, was a loss of $4.3 million, compared to a loss of $3.7 million in the third quarter of 2023 and a loss of $3.8 million in the fourth quarter of 2022. For more information regarding non-GAAP financial measures discussed in this press release, please see "Non-GAAP Financial Measures" below, as well as the reconciliation of non-GAAP measures to the nearest GAAP measure, provided in the tables below.

Cash and cash equivalents totaled $5.3 million as of December 31, 2023. The Company subsequently raised gross proceeds of $7.5 million in March 2024 through the closing of the Zylox-Tonbridge initial equity investment.

Concurrent with the Zylox-Tonbridge initial investment, CRG Partners, the primary holder of Avinger debt and preferred equity exchanged its Series A preferred stock with an aggregate liquidation preference of approximately $60 million for new Series A-1 preferred stock with a value of $10 million. The new Series A-1 preferred stock is convertible at a conversion price of $3.66 per share and carries no liquidation preference or dividend preference. Additionally, CRG extended principal payments on Avinger's debt from the first quarter of 2024 to the first quarter of 2027, with interest payments accruing during this time.
