BIO-TECHNE RELEASES FIRST QUARTER FISCAL 2020 RESULTS

Minneapolis/October 29, 2019/ Bio-Techne Corporation (NASDAQ:TECH) today reported its financial results for the first quarter ended September 30, 2019.

First Quarter FY2020 Snapshot

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

“We opened fiscal 2020 posting an outstanding first quarter,” said Chuck Kummeth, President and Chief Executive Officer of Bio-Techne. “The 13% organic growth for the quarter was the result of very good execution from our global team and our strong product portfolio, which remains extremely vital in research workflow for our customers.”

Kummeth added, “Our end-markets, including BioPharma and Europe, remain healthy, while China continues to outperform at nearly 20% growth. I’m very proud of the team for this excellent start to the year and very optimistic about our future execution and growth due to all the exciting new products and services we offer as a valued partner to researchers worldwide. ”

First Quarter Fiscal 2020

Revenue

Net sales for the first quarter increased 12% to $183.2 million. Organic growth was 13% compared to the prior year, with foreign currency exchange having an unfavorable impact of 1% and acquisitions contributing less than 1% to revenue growth.

GAAP Earnings Results

GAAP EPS decreased to $0.37 per diluted share, versus $0.45 in the same quarter last year. GAAP EPS was unfavorably impacted by an unrealized loss on our ChemoCentryx investment. GAAP operating income for the first quarter of fiscal 2020 increased 29.4% to $33.3 million, compared to $25.8 million in the first quarter of fiscal 2019. GAAP operating margin was 18.2%, compared to 15.8% in the first quarter of fiscal 2019. GAAP operating margin compared to prior year was positively impacted by the timing of stock compensation expense recognized as a result of adding new requirements for certain vesting eligibility.

Non-GAAP Earnings Results

Adjusted EPS increased to $1.06 per diluted share, versus $0.98 in the same quarter last year, an increase of 8% resulting from higher sales volumes. Adjusted operating income for the first quarter of fiscal 2020 increased 6% compared to the first quarter of fiscal 2019. Adjusted operating margin was 31.8%, compared to 33.9% in the first quarter of fiscal 2019. Adjusted operating margin compared to the prior year was negatively impacted by recent acquisitions and unfavorable foreign exchange rates.

Segment Results

Management uses adjusted operating results to monitor and evaluate performance of the Company’s business segments, as highlighted below. Since these results are used for this purpose, they are also considered to be prepared in accordance with GAAP.

Additionally, the segment provides an array of platforms useful in various areas of protein analysis.

Protein Sciences segment’s operating margin was 42.2% in the first quarter of fiscal 2020 compared to 43.2% in the first quarter of fiscal 2019. The segment’s operating margin compared to the prior year was negatively impacted by product mix and unfavorable foreign exchange.

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:

● Organic growth

● 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 measure of organic growth represents revenue growth excluding revenue from acquisitions within the preceding 12 months as well as the impact of foreign currency. Excluding these measures provides more useful period-to-period comparison of revenue results as it excludes the impact of foreign currency exchange rates, which can vary significantly from period to period, and revenue from acquisitions that would not be included in the comparable prior period.

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, which is inclusive of the employer portion of payroll taxes on those stock awards, 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, variety of award types, and unpredictability of amount and timing of employer related tax obligations. 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.
