This proxy statement supplement (this “Supplement”), dated December 3, 2021, supplements and amends the proxy statement filed with the Securities and Exchange Commission on November 5, 2021 (the “Proxy Statement”) relating to the proxies being solicited by the Board of Directors (the “Board”) of Avinger, Inc., a Delaware corporation (the “Company” and “we,” “us” or “our”), in connection with our 2021 Annual Meeting of Shareholders to be held on December 20, 2021. This Supplement should be read together with the Proxy Statement. Other than as set forth below, no changes have been made to the Proxy Statement.

Engagement of Proxy Solicitor

Subsequent to filing the Proxy Statement, we engaged The Proxy Advisory Group, LLC, an independent proxy solicitation firm, to assist in soliciting proxies on our behalf. The Company has agreed to pay a fee of $6,000, plus costs and expenses, for these and related services.

Expenses and Manner of Solicitation

As noted in the Proxy Statement, we will bear the expense of soliciting proxies by the Board. We will reimburse brokers or other nominees for reasonable expenses that they incur in sending our proxy materials to you if a broker, bank or other nominee holds shares of our common stock on your behalf.  In addition, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication.  Our directors and employees will not be paid any additional compensation for soliciting proxies.
