(NASDAQ: BRLI) announces best-ever quarterly results for revenues despite significant reimbursement changes noted in the Company’s earlier announcement regarding quarterly headwinds.  Except for per share data or where otherwise noted, numbers are in thousands and all comparisons to prior periods are adjusted in accordance with the Accounting Standards Update 2011-7 under Topic 954 of FASB codification.  The appended table reflects the adjustments for the prior period.

The Company recorded Q4FY13 revenues of $192,219, the strongest quarterly revenues in corporate history and an increase of 18% over the $163,487 ($176,052 as previously reported) recorded in Q4FY12.  The Company announced on November 27, 2013 that the Company believed there had been an industry-wide recalibration of reimbursements that, along with certain extraordinary expenses during the quarter, would have a negative impact on Company earnings.  In that vein, net income before taxes in Q4FY13 totaled $19,773, a decrease of 14% compared with net income before taxes of $22,966 recorded in Q4FY12. Net income after tax for Q4FY13 totaled $11,120 or $.40 per share, as compared with $12,889, or $.46 per share, in Q4FY12.  Gross profits on revenues for Q4FY13 were $85,282, which resulted in a margin for gross profit on revenues of 44%, compared to $74,681 ($87,245 as previously reported) reported in Q4FY12, which resulted in a in a margin for gross profit on revenues of 46%.  Revenue per patient for Q4FY13 was $80.80, an increase of 1% from the $79.66 ($85.83 as previously reported) reported for Q4FY12. The number of patients served increased 15% to 2,350 in Q4FY13 from the Q4FY12 total of 2,039.  Esoteric business for the Company was 65% of revenues for Q4FY13 compared to 61% in Q4FY12.  Days Sales Outstanding (DSO) was at 99 days for Q4FY13 compared to Q4FY12 when DSO was 87 days (80 days as previously reported).  Cash flow from operations for the current quarter, while positive, was just less than $1,000.

Full year revenues increased to $715,354, an increase of 16% over revenues of $614,255 ($661,661 as previously reported) in the prior fiscal year.  Net income after taxes for the current year was $45,825 resulting in an EPS of $1.65; this was an increase of 9% from the prior fiscal year net income after taxes of $42,156, which resulted in an EPS of $1.51 for FY2012.  The Company reported gross profit on revenues for the 2013 fiscal year of $322,539, resulting in a margin for gross profit on revenues of 45% compared to the prior year same period of $276,611 ($324,017 as previously reported) which also resulted in a margin for gross profit on revenues of 45%.  The number of patients served increased 10% to 8,549 in FY13 from the FY12 total of 7,801.  Cash flow from operations for the year was approximately $17,662.

The Company further noted in FY2013, it bought back 81,600 shares pursuant to its 2012 Stock Repurchase Resolution to buyback up to 714,550 shares of its common stock; that Repurchase Program expired on October 31, 2013. The Company announced today that its board of directors has approved a new Stock Repurchase Program authorizing the buyback of up to 2,000,000 shares of its Common Stock in the over-the-counter market at prevailing market prices through October 31, 2015.

Marc D. Grodman, MD, CEO, commented: “BioReference remains more than ever a growth company, grounded in innovation.  BioReference has contemplated, conceived and implemented not only new testing modalities that have led the market but we have also created franchises that are readily identified by specialist physicians around the country as the source and provider of these new innovative testing services.  Nonetheless, over the past year, specifically during the fourth quarter of FY13, we identified a significant reduction in reimbursement, particularly from commercial payers.  We previously disclosed that we had identified a sequential drop in quarterly revenue, excluding our genetic testing revenues, in the aggregate amount of approximately 4% from Q3FY13 to Q4FY13.  The reduction in reimbursement from payers is an industry-wide issue that we believe has been observed by many companies in our space.  Simultaneously, we experienced significant expenses relating to the integration of our acquisitions in Florida and California as well as the initial rollout of our Inherited Cancers program at GeneDx.  While the expenses related to the integration of acquisitions and the Inherited Cancer program adversely affected our Q4FY13 results of operations, we believe they will also be the foundations for our growth in 2014 and beyond.”

Dr. Grodman further noted: “We need to adjust to the changing reimbursement landscape by intelligently and efficiently identifying areas where we can reduce expenses without affecting customer service and support or innovation.  We have already identified several such areas and have begun implementing such expense reductions.  These steps will take some time to produce improved results, but we anticipate gains progressively throughout 2014 as a result of these changes.  On the other hand, we are encouraged by the strong volumes so far in the current fiscal year in all aspects of our business.  We are composed of several franchise marketing groups and each has shown opportunities for growth.  We believe the industry is and will remain under pressure, but in that pressure we see opportunity.  Based on a combination of all our initiatives, we look forward to the upcoming year.”

Dr. Grodman completed his comments by stating: “In our press release last month, we announced our expectation that, based on the current environment, the Company’s operations would result in an increase in net revenues of 10%, an increase in patient volume of 10% and an increase in net income of 10% in FY14.  We affirm that guidance for the coming year.  Over the course of the year, we will continue to review our results in light of the prevailing conditions.”
