ELMWOOD PARK, NJ (June 5, 2014) BioReference Laboratories, Inc. (NASDAQ: BRLI) announces record second quarter results for revenues and patient volumes.  Except for per share data or where otherwise noted, numbers are in thousands.

The Company recorded Q2FY14 revenues of $201,366, the highest recorded revenues in a quarter in corporate history, representing an increase of 14% over the $176,452 recorded in Q2FY13 despite the adverse effects of weather during the quarter that resulted in a reduction of revenue that the Company estimates at $5,000.  Operating income for Q2FY14 was $18,879, down 9% from the Q2FY13 operating income of $20,709.  Net income after taxes in Q2FY14 came in at $10,273, resulting in earnings per share of $.37, down from Q2FY13 net income after taxes of $11,338 and EPS of $.41, decreases of 9% and 10%, respectively.  The Company estimates that the adverse effects of weather during Q2FY14 resulted in approximately a $.05 reduction in EPS.  Gross profit on revenues for Q2FY14 was $88,549, resulting in a margin for gross profit on revenues of approximately 44% and a 10% improvement over the gross profit on revenues of $80,676 recorded for Q2FY13, which resulted in a 46% margin.  Revenue per patient for Q2FY14 was $84.18, a decrease of 1% from the $84.93 recorded for Q2FY13, in line with the Company’s prior observations about reimbursement pressures.  The number of patients served increased 14% to 2,364 in Q2FY14 up from the Q2FY13 total of 2,066.  Esoteric business for the Company was 68% of revenues for Q2FY14 compared to 63% in Q2FY13.  Days Sales Outstanding (DSO) was 105 days in Q2FY14 compared to Q2FY13 when the DSO was 89 days and down from the 111 days reported in Q1FY14.

Revenues for the first six-months of FY14 increased to $382,635, an increase of 13% over the revenues for the first six months of FY13 of $337,709, even though the first six months of FY14 included the effects of adverse weather which the Company estimates reduced revenues by $10,000.  Operating income for the first six months of FY14 was $24,760, a decrease of 32% from FY13 six-month operating income for the first six months of FY13 of $36,468.  Net income after taxes for the first six months of FY14 was $13,227, resulting in an EPS of $.47, a decrease of 34% from the first six-months FY13 net income after taxes of $20,003, which resulted in an EPS of $.72.  The Company estimates that the adverse effects of weather during the first six months of FY14 resulted in approximately a $.10 reduction in EPS. The Company reported gross profit on revenues for the FY14 first six-month period of $160,703, resulting in a margin for gross profit on revenues of 42%, up from gross profit on revenues in the FY13 first six-month period of $151,598, which resulted in a margin of 45%.  The number of patients served increased 13% to 4,571 in the first six months of FY14 from the FY13 same period total of 4,038.  Cash flow from operations for the first six months of FY14 was a negative $188, compared to a positive $12,832 in the prior year same period, although significantly better than aggregate net negative cash flow from operations reported over the previous two reported quarters.

Marc D. Grodman, MD, CEO, commented: “We grew patient volumes and revenues by over 14%. Our net income during the current quarter, when adjusted for the impact of the weather, is comparable to where we were in the same quarter last year despite the changes in reimbursement and the added infrastructure from our investments in Florida and California..  Although we previously estimated that the weather would negatively affect this quarter by anywhere from $.05-$.07, we have now calculated that weather resulted in a $.05 reduction in our earnings in Q2FY14.  Although reimbursements are down from last year, we believe that most of the pricing pressures are behind us and remain comfortable with 5% decrease we

reported earlier. The fact that CMS, based on the recent SGR legislation, is not proposing significant changes until 2017 supports this thesis.”

Dr. Grodman continued: “Our growth was fueled by a commitment to specialty testing and our investments in Genetics, Cancer and Women’s Health.  Increasingly, the expertise of GeneDx is merging with the strengths of all the BioReference offerings. The growth at GeneDx was fueled by our leadership position in exome analysis, the cutting edge and differentiating genetic service we provide, as well our growing volume of Inherited Cancer testing.  We have built our Inherited Cancer program carefully and thoroughly over the past six months and it is being well received in the healthcare community.  By all metrics, we believe that we are more than competitive and it is important to note that we have been doing next generation sequencing on a commercial basis longer than any other commercial laboratory in our space and we believe this gives us an advantage in the market.”

Dr. Grodman finally noted: “This is a transition year for us, combining the need to grow with expense reduction, and the challenge to accomplish it while significantly outgrowing the market. Our past investments in genetics and other specialty testing have positioned us well to take advantage of this new environment.  Given all the changes that have occurred this year we have provided more specific guidance than we have in the past. As we have previously stated, we believe that we will just about equal our performance for the third quarter of last year in the coming third quarter of this year. We also believe that the fourth quarter will show improvement over the fourth quarter of last year.  We believe that if it had not been for the $0.10 downward effect from weather that we have reported, we would finish with approximately a 10% improvement over last year.”
