Avinger Provides Strategic Update

Announces Preliminary First Quarter 2017 Results

Redwood City, California, April 10, 2017 — Avinger, Inc. (NASDAQ: AVGR) (the “Company”), a leading developer of innovative treatments for peripheral artery disease (“PAD”), today provided an update on several aspects of its business, including preliminary results for the first quarter of 2017, an organizational realignment, and continued progress on product development and clinical initiatives.  The Company also announced that it has been conducting a review of various strategic alternatives focused on maximizing shareholder value. Potential strategic alternatives being explored and evaluated as part of this review include, but are not limited to, raising capital from strategic investors, partnerships for distribution of products outside the U.S., and a sale or merger of the Company.

“Avinger has achieved a great deal in the last year by bringing Pantheris OCT-guided atherectomy to market, increasing our installed base of Lumivascular accounts and presenting compelling two-year data from our VISION study. However, we have also encountered challenges with product reliability and the broad commercialization of our Lumivascular technology. Consequently, we have decided to make adjustments in our business as we prepare for the launch of our next generation Pantheris and Below-the-Knee products in late 2017 and early 2018,” said Jeff Soinski, Avinger’s president and CEO. “Our organizational realignment, cost reduction measures and the exploration of strategic initiatives are all intended to maximize shareholder value.”

Preliminary First Quarter 2017 Results

Based on preliminary unaudited financial results, Avinger expects total revenue of approximately $3.5 million for the first quarter ended March 31, 2017, a decrease of 22% from the first quarter of 2016 and a decrease of 26% from the fourth quarter of 2016.

Revenue from disposable devices is expected to be $2.9 million for the first quarter of 2017, a 12% decrease compared to the first quarter of 2016 and a 22% decrease from the fourth quarter of 2016. Revenue related to Lightbox imaging consoles is expected to be $0.6 million, a 50% decrease compared to the first quarter of 2016 and a 40% decrease from the fourth quarter of 2016.

During the first quarter of 2017, the installed base of Lumivascular accounts increased by five and ended the quarter at 161 accounts.

Cash and cash equivalents totaled $23.0 million as of March 31, 2017, compared to $36.1 million as of December 31, 2016.

Business Update

Avinger’s top priority for 2017 is to complete the next generation Pantheris projects, which are expected to improve product reliability and usability and expand the Company’s market opportunity by treating smaller vessels below the knee. In addition, the Company expects to begin enrollment in an in-stent restenosis trial for Pantheris. Avinger’s R&D and manufacturing teams expect to continue to introduce incremental improvements to the current version of the Pantheris catheter to improve the consistency and reliability of the currently marketed product, while next generation devices are in development.  A more detailed description of these initiatives is as follows:

·Pantheris 3.0: Next generation atherectomy catheter designed to enhance product reliability and incorporate additional features and improvements desired by physicians, such as a single balloon inflation system, a longer nosecone option, a stiffer shaft for enhanced pushability, and markings on the shaft for longitudinal measurement. The Company expects to file a 510(k) application for Pantheris 3.0 during the third quarter of 2017.

·Pantheris BTK: A six-French version of Pantheris incorporating next generation improvements and designed to facilitate below-the-knee (BTK) procedures, which is expected to meaningfully expand the applicable market for Avinger’s products. The Company expects to file a 510(k) application for this device in the fourth quarter of 2017.

·In-Stent Restenosis Trial: The Company has filed an investigational device exemption (IDE) with the FDA to initiate a Pantheris in-stent restenosis (ISR) trial. Following FDA review of the trial protocol, the Company expects patient enrollment to begin in the third quarter of this year.  If successful, Pantheris will be the second atherectomy product indicated for in-stent restenosis, a segment estimated to represent approximately 20% of PAD procedures in the U.S.

On the clinical evidence front, positive interim two-year clinical data from the pivotal VISION study of the Company’s Lumivascular technology were presented in January at LINC and final results are expected to be released by the end of June 2017.

Organizational Realignment

The Company is reducing its workforce by approximately 33% compared to year-end 2016, to a total of 131 full-time equivalent employees, under a plan expected to be substantially completed this week. The plan is designed to focus the Company’s commercial efforts on driving catheter utilization in its strongest markets, around its most productive sales professionals. The Company’s field sales personnel will be reduced to 32 down from 60 people as of December 31, 2016. This workforce reduction is designed to reduce operating expenses while continuing to support major product development and clinical initiatives. The strategic reduction in the field sales force is designed to maintain robust engagement with higher volume users of the Company’s Lumivascular technology by its highest performing sales representatives and position the Company to return to growth in 2018 behind the launch of its next generation products.

Based on the organizational changes and other expense reduction measures, the Company expects cash utilization to decrease to approximately $7 million per quarter by the second half of 2017, compared to an average of $13.5 million per quarter in 2016 and $13.1 million in the first quarter of 2017. The Company expects cash currently on hand will be sufficient to fund the operations through the end of 2017.
