Quotient Limited Announces Estimated Third Quarter Fiscal 2016 Financial Results

JERSEY, Channel Islands, February 3, 2016 (GLOBENEWSWIRE) — Quotient Limited (NASDAQ:QTNT), a commercial-stage diagnostics company, today announced estimated financial results for its fiscal third quarter ended on December 31, 2015. Quotient’s estimated financial results for the three months ended December 31, 2015 presented below are preliminary and are subject to the completion of its quarter-end closing procedures and financial review:

• For the three months ended December 31, 2015, Quotient’s product sales increased approximately 8-10%, compared with product sales for the three months ended December 31, 2014 of $4.0 million. The increase in product sales for the three months ended December 31, 2015 compared with the corresponding period in 2014 is mainly attributable to growth in direct sales of conventional reagent products to customers in the United States.

• Quotient continued to incur an operating loss for the three months ended December 31, 2015. This operating loss is expected to represent an increase compared with Quotient’s operating loss for the three months ended December 31, 2014 of $7.3 million.

• Quotient had approximately $24.1 million in cash and cash equivalents at December 31, 2015.

Quotient’s actual results may differ from these estimates as a result of the completion of its quarter-end closing procedures, review adjustments and other developments that may arise between now and the time its financial results for this period are finalized. In addition, these preliminary results of operations ended December 31, 2015 are not necessarily indicative of the results to be achieved for the remainder of the fiscal year ending March 31, 2016 or in any future period. Quotient expects to release final third quarter fiscal 2016 financial results before the market open on February 8, 2016.
