Item 1.01. Entry into a Material Definitive Agreement.

On August 15, 2018, IntriCon Corporation (the “Company” or “IntriCon”) entered into an Underwriting Agreement (the “Underwriting Agreement”) with Stifel, Nicolaus & Company, Incorporated as representative of the several underwriters named therein (collectively, the “Underwriters”), relating to the issuance and sale of 1,500,000 shares common stock, $1.00 par value per share (the “Common Stock”) at a price to the public of $55.00 per share less an underwriting discount of $3.30 per share. Pursuant to the Underwriting Agreement, the Company granted the Underwriters a 30-day option to purchase up to an additional 225,000 shares of Common Stock.

The offering was made pursuant to the Company’s effective registration statement on Form S-3 (Registration Statement No. 333-226334) previously filed with and declared effective by the Securities and Exchange Commission (the “SEC”) and a prospectus supplement and accompanying prospectus filed with the SEC.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties.

The Underwriters have in the past, or may in the future, provide various investment banking and other financial services for the Company for which services they have received or may in the future receive, customary fees.

The foregoing description of the Underwriting Agreement is qualified in its entirety by reference to the full text of the Underwriting Agreement, a copy of which is attached hereto as Exhibit 1.1 and is incorporated herein by reference. A copy of the validity opinion of Blank Rome LLP with respect to the shares of Common Stock sold in the offering is attached hereto as Exhibit 5.1.

The Company issued press releases on August 15, 2018 and August 20, 2018 announcing the pricing of its previously announced underwritten public offering and the completion of such offering, respectively, which press releases are furnished herewith as Exhibits 99.1 and 99.2, respectively, to this report.

Item 8.01 Other Events.

On August 20, 2018, the Company completed the issuance and sale of 1,725,000 shares of Common Stock, including 225,000 shares sold pursuant to the exercise in full of the Underwriters’ option to purchase additional shares, pursuant to the Underwriting Agreement at a price to the public of $55.00 per share (the “Offering”). The Company estimates that the net proceeds from the Offering, including pursuant to the option exercise, after deducting underwriting discounts and commissions and estimated offering expenses, will be approximately $88.9 million. The Company intends to use the net proceeds from the Offering to repay debt, to fund capital expenditures, to repurchase 500,000 shares of its common stock from certain of its
