Alere Inc. Announces Commencement of Consent Solicitation Related to its 7.250% Senior Notes due 2018, 8.625% Senior Subordinated Notes due 2018 and 6.500% Senior Subordinated Notes due 2020.

WALTHAM, Mass., May 21, 2014 – Alere Inc. (NYSE: ALR) (the “Company”) announced today that it has commenced a consent solicitation relating to its 7.250% Senior Notes due 2018 (the “7.250% Notes”), its 8.625% Senior Subordinated Notes due 2018 (the “8.625% Notes”) and its 6.500% Senior Subordinated Notes due 2020 (the “6.500% Notes,” and, together with the 7.250% Notes and the 8.625% Notes, the “Notes”). The Company is soliciting the consents of the requisite holders of the Notes as of the record date set forth in the solicitation documents (the “Solicitation Documents”) to certain waivers (the “Proposed Waivers”) and amendments (the “Proposed Amendments” and, together with the Proposed Waivers, the “Proposed Waivers and Amendments”) of provisions of the indentures governing the Notes (the “Indentures”).

The primary purpose of the Proposed Waivers and Amendments is to (i) waive the provisions of each of the Indentures as necessary in order to allow the Company and its subsidiaries to enter into, consummate the transactions contemplated by, and perform their obligations with respect to the BBI Transaction (as defined below), and (ii) modify certain provisions of each of the Indentures as set forth in the Proposed Amendments, in each case subject to the satisfaction of certain requirements. The permissions created by the Proposed Waivers and Amendments would be in addition to all other existing permissions and exceptions under the restrictive covenants in the respective Indentures (as modified by the Proposed Waivers and Amendments), which permissions and exceptions will (except as modified by the Proposed Waivers and Amendments) remain in place, will not be reduced by the Proposed Amendments, will continue to be calculated in the same manner and may, where applicable, increase in accordance with their terms.

The “BBI Transaction” is broadly defined in the Solicitation Documents as the previously announced proposed initial public offering by the Company’s subsidiary BBI Diagnostics Group plc (“BBI”) of its ordinary shares in the United Kingdom and the sale of such shares in certain other jurisdictions, together with the related transactions anticipated to be conducted by the Company and its subsidiaries in connection therewith as previously announced by the Company.

The implementation of the Proposed Waivers and Amendments is subject to the valid delivery of consents by holders (as of the relevant record date) of Notes constituting a majority of the outstanding principal amount of the 7.250% Notes, a majority of the outstanding principal amount of the 8.625% Notes and a majority of the outstanding principal amount of the 6.500% Notes, respectively, (collectively, the “Requisite Consents”), the acceptance of the consents by the Company, as well as the other conditions set forth the Solicitation Documents, including the execution of supplemental indentures effecting the Proposed Waivers and Amendments with respect to the Indentures. If these conditions are satisfied or waived, and the Proposed Waivers and Amendments are implemented , the Proposed Waivers and Amendments will become operative only upon the Company’s making consent payments to holders (as of the record date) of Notes who validly deliver and do not revoke their consents on or before the applicable

expiration date. However, the fact that the Requisite Consents are received (and not revoked) on or before the expiration date will not obligate the Company to accept any consents, and acceptance of the consents will not obligate the Company to implement the Proposed Waivers and Amendments, to make the Proposed Waivers and Amendments operative by paying the consent fee (which payment shall be in the Company’s sole discretion) or to consummate the BBI Transaction.

The solicitation of consents is scheduled to end at 5:00 p.m., New York City time, on June 4, 2014, unless extended or earlier terminated.

Jefferies LLC is acting as the solicitation agent and IPREO LLC is acting as the information and tabulation agent in connection with the consent solicitation.
