BIO-TECHNE RELEASES FOURTH QUARTER FISCAL 2015 RESULTS

Minneapolis/August 6, 2015/ Bio-Techne Corporation (NASDAQ:TECH) today reported its financial results for the fourth quarter ended June 30, 2015.

Fourth Quarter Snapshot and Full Year 2015 Highlights

Adjusted EPS, adjusted earnings, adjusted gross margin, adjusted operating income, and adjusted operating margin are non-GAAP measures that exclude certain items detailed later in this press release under the heading “Use of Adjusted Financial Measures.”

“I am pleased to report that we achieved 7% organic revenue growth for the quarter,” said Chuck Kummeth, President and Chief Executive Officer of Bio-Techne. “the best growth we have achieved in many years. China had a fantastic quarter with 35% organic growth, and we saw our academic markets return to growth in the U.S. Foreign currency exchange rate impact continues to be a headwind to both our top and bottom line, impacting margins negatively. But operationally, we achieved our planned operating margins while making the selective investments required to enable organic growth for years to come.”

“I am very proud of our team’s accomplishments over the past fiscal year. On the acquisition front, we put our capital to work by greatly expanding our antibody offering to our customers with the acquisition and integration of Novus. And with the acquisition of ProteinSimple and CyVek, we offered our customers new solutions for better results and increased productivity on key workflows such as Western Blot and multiplex-ELISA. The new members of the Bio-Techne family also worked closely with our Minneapolis-based R&D Systems team to create unique assays and optimized reagent solutions for these platforms that provide additional value to our customers.”

“In our core business, we reversed the multi-year trend of negative growth in our academic market as our partnership with Fisher Scientific built momentum throughout the year. We continued to focus on innovation, with a market-based approach using key opinion leaders. This prioritization process led to a 60% improvement in first year product sales in 2015. We launched a new website that greatly enhances our customers’ online experience, making it much easier for the researcher to find the reagents for their experiments with the expectations of converting these experiences into purchasing transactions. And finally, in China, the teams persevered to grow well north of 20% despite the market turbulence caused by the Chinese government’s audit crackdown during the year.”

Kummeth concluded, “2015 was a pivotal year for Bio-Techne. We invested selectively, yet purposefully, on the acquisition front, in human capital, and organically in the core business. These investments, together with the talent of our employees, should reap rewards for years to come.”

Biotechnology segment adjusted operating margin was 52.4 % in the fourth quarter of fiscal 2015 compared to 55.8% in the fourth quarter of fiscal 2014. The lower margin is a result of the acquisition of Novus Biologicals in fiscal year 2015 and the impact of foreign exchange translation.

Biotechnology segment adjusted operating margin was 52.5 % in fiscal 2015 compared to 55.9% in fiscal 2014.
