Alere Reports Third Quarter 2016 Financial Results

WALTHAM, Mass., November 4, 2016 – Alere Inc. (NYSE: ALR), a global leader in rapid diagnostic tests, today announced that it has filed its Form 10-Q and reported financial results for the third quarter ended September 30, 2016.

Revenue for the third quarter of 2016 was $582 million, a 4% decrease compared to $604 million in the prior year period. Infectious disease revenue grew 11% or $19 million year-over-year with strength in Africa and Latin America, particularly in malaria and HIV product sales. This strong growth was offset by revenue declines of $15 million due to the divestiture of BBI in November 2015, $12 million in mail order diabetes and $7 million in Toxicology. Foreign currency had a negative impact of $4 million and organic growth was -0.7% during the third quarter of 2016.

Net income (loss) from continuing operations during the third quarter of 2016 was $22 million, or $0.19 per basic and diluted share, compared to $(2) million, or $(0.10) per basic and diluted share in the prior year period. On a non-GAAP basis, the Company reported non-GAAP adjusted EBITDA of $64 million in the third quarter of 2016, compared to $135 million in the prior year period. The year-over-year decrease was primarily driven by $41 million in merger and legal-related expenses, $12 million of investments in infrastructure and performance improvement initiatives and $5 million in acquisition costs.

Certain amounts presented may not recalculate directly, due to rounding.

Non-GAAP Information

To supplement the financial measures prepared in accordance with U.S. GAAP, the Company uses non-GAAP adjusted EBITDA and organic growth, which are non-GAAP financial measures. The reconciliations of non-GAAP adjusted EBITDA to net income (loss) from continuing operations and organic growth to revenue, the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP, is shown in the table in this press release. The Company believes non-GAAP adjusted EBITDA and organic growth are useful to investors because these metrics are commonly used by investors to assess the unleveraged, pre-tax financial performance and operating results of ongoing business operations. The Company’s management also uses non-GAAP adjusted EBITDA and organic growth because the Company’s management also believes that these are useful measures to evaluate operating performance and cash flows of the Company based on operational factors. It should also be noted that not all companies calculate non-GAAP adjusted EBITDA and organic growth in the same manner and, accordingly, these measures presented in this press release may not be comparable to similar measures used by other companies.

Conference Call

As announced on February 1, 2016, Alere entered into a definitive agreement under which Abbott will acquire Alere for $56 per common share. Due to the pending transaction, Alere will no longer hold conference calls to discuss its quarterly financial results.
