Second Quarter FY2019 Snapshot

● Second quarter organic revenue increased by 11% (13% reported) to $174.5 million.

● GAAP EPS was $0.45 vs. $1.29 one year ago. Current Year GAAP EPS saw a one-time benefit for tax reform of $0.02 compared to a prior year GAAP EPS benefit of $0.94. Delivered adjusted earnings per share (EPS) of $1.06, an increase of 4% over the prior year.

● Protein Sciences Segment delivered 14% organic growth with broad double-digit growth in most consumable and instrument product categories.

● The National Comprehensive Cancer Network (NCCN) included EPI as a recommended test in their Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Prostate Cancer Early Detection.

The company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (GAAP). Adjusted dilutive EPS, adjusted net 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 non-GAAP Adjusted Financial Measures.” A reconciliation of GAAP to non-GAAP financial measures is included in this press release.

“A truly outstanding quarter with 11% organic growth, especially considering a comparable of 14% organic growth in the same quarter last year”,  said Chuck Kummeth, President and Chief Executive Officer of Bio-Techne. “The team really performed well this quarter in most product categories and all regions.  We were particularly impressed with China, with two quarters in a row of over 30% organic growth, a first for Bio-Techne.”

Kummeth added, “The rest of Asia also performed very well in Q2 as they have for many quarters. We are seeing some critical mass with our company platforms in Asia, and the need for both our reagent and instrument products continues to grow within these expansive emerging markets. Our brands continue to be the go-to choice for researchers in both academia and biopharma markets due to our consistent top quality, an ever expanding GMP menu, and our unique automated solutions for many labor intensive laboratory procedures.”

Kummeth concluded, “For the first half of our fiscal year, we have achieved double-digit organic growth over a prior year which also experienced double-digit growth. It has taken us years to reach this point of executing on our strategy, and the team is excited about our ability to see it continue.”

Use of non-GAAP Adjusted Financial Measures:

This press release contains financial measures that have not been calculated in accordance with accounting principles generally accepted in the U.S. (GAAP). These non-GAAP measures include:

● Adjusted diluted earnings per share

● Adjusted net earnings

● Adjusted gross margin

● Adjusted operating income

● Adjusted operating margin

We provide these measures as additional information regarding our operating results. We use these non-GAAP measures internally to evaluate our performance and in making financial and operational decisions, including with respect to incentive compensation. We believe that our presentation of these measures provides investors with greater transparency with respect to our results of operations and that these measures are useful for period-to-period comparison of results.

Our non-GAAP financial measures for adjusted gross margin, adjusted operating margin, and adjusted net earnings, in total and on a per share basis, exclude the costs recognized upon the sale of acquired inventory, amortization of acquisition intangibles, and acquisition related expenses. The Company excludes amortization of purchased intangible assets and purchase accounting adjustments, including costs recognized upon the sale of acquired inventory and acquisition-related expenses, from this measure because they occur as a result of specific events, and are not reflective of our internal investments, the costs of developing, producing, supporting and selling our products, and the other ongoing costs to support our operating structure. Additionally, these amounts can vary significantly from period to period based on current activity.

The Company’s non-GAAP adjusted operating margin and adjusted net earnings, in total and on a per share basis, also excludes stock-based compensation expense, restructuring, impairments of equity method investments, gain and losses from investments, and certain adjustments to income tax expense. Stock-based compensation is excluded from non-GAAP adjusted net earnings because of the nature of this charge, specifically the varying available valuation methodologies, subjective assumptions, and the variety of award types. Impairments of equity investments are excluded as they are not part of our day-to-day operating decisions. Additionally, gains and losses from other investments that are either isolated or cannot be expected to occur again with any predictability are excluded.   Costs related to restructuring activities, including reducing overhead and consolidating facilities, are excluded because we believe they are not indicative of our normal operating costs. The Company independently calculates a non-GAAP adjusted tax rate to be applied to the identified non-GAAP adjustments considering the impact of discrete items on these adjustments and the jurisdictional mix of the adjustments. In addition, the tax impact of other discrete and non-recurring charges which impact our reported GAAP tax rate are adjusted from net earnings. We believe these tax items can significantly affect the period-over-period assessment of operating results and not necessarily reflect costs and/or income associated with historical trends and future results.

Investors are encouraged to review the reconciliations of adjusted financial measures used in this press release to their most directly comparable GAAP financial measures as provided with the financial statements attached to this press release.
