Item 8.01 Other Events.

On May 9, 2018, Integra LifeSciences Holdings Corporation (“Integra”) entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC and Wells Fargo Securities, LLC (the “Underwriters”), in connection with a registered underwritten public offering of Integra’s common stock, par value $0.01 per share (“Common Stock”). Subject to the terms and conditions of the Underwriting Agreement, Integra agreed to sell to the Underwriters, and the Underwriters agreed to purchase from Integra, an aggregate of 5,250,000 shares of Common Stock, at a public offering price of $58.50 per share. Integra also granted the Underwriters a 30-day option to purchase up to an additional 787,500 shares of Common Stock, which was exercised in full on May 10, 2018. The parties have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act of 1933, as amended. The offering, including the shares of Common Stock pursuant to the Underwriters’ option to purchase additional shares, closed on May 14, 2018.

Integra estimates its net proceeds from the offering to be approximately $350 million, after deducting underwriting discounts and commissions and estimated offering expenses. Integra intends to use the net proceeds from the Offering to reduce outstanding revolving borrowings under Integra’s senior credit facility.

The sale of the shares of Common Stock was registered pursuant to a Registration Statement on Form S-3 (Registration Statement No. 333-214430) (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”), including the prospectus supplement filed by Integra with the Commission, dated May 9, 2018 (the “Prospectus Supplement”), to the prospectus contained in the Registration Statement dated November 4, 2016.

Pursuant to the terms of the Underwriting Agreement and related lock-up agreements, Integra and all of its directors and executive officers also agreed not to sell or transfer any Common Stock held by them for 90 days after May 9, 2018 without first obtaining the written consent of the Underwriters, subject to certain exceptions as described in the Prospectus Supplement.

A copy of the Underwriting Agreement is filed as Exhibit 1.1 to this Current Report and is incorporated herein by reference, and the description of the terms of the Underwriting Agreement herein is qualified in its entirety by reference to such exhibit. The Underwriting Agreement is also filed with reference to, and is hereby incorporated by reference into, the Registration Statement.

Attached as Exhibit 5.1 to this Current Report and incorporated herein by reference is a copy of the opinion of Sullivan & Cromwell LLP relating to the validity of the shares of Common Stock that may be sold in the Offering (the “Legal Opinion”). The Legal Opinion is also filed with reference to, and is hereby incorporated by reference into, the Registration Statement.

This Current Report does not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction. Any offer, if at all, will be made only by means of the Prospectus Supplement and the accompanying prospectus, forming a part of the effective Registration Statement.
