BIO-TECHNE RELEASES FOURTH QUARTER FISCAL 2017 RESULTS

Minneapolis/August 8, 2017/ Bio-Techne Corporation (NASDAQ:TECH) today reported its financial results for the fourth quarter and full year end ended June 30, 2017.

Fourth Quarter and Full Year FY2017 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 Adjusted Financial Measures.” A reconciliation of GAAP to non-GAAP financial measures is included in this press release.

“Q4 was a great quarter to end a great fiscal year 2017. I'm very proud of our global team, now totaling 1800 worldwide, and their exemplary performance all year,” said Chuck Kummeth, President and Chief Executive Officer of Bio-Techne. “We grew 13 percent in revenue on an annual basis with a solid 6 percent organic growth. Our two fastest growing businesses, Protein Platforms and ACD, finished the year as strong as they started with PPD revenue growing nearly 20% and ACD revenue growing over 50% (on a stand-alone basis) for the full year.”

Kummeth added, “Integration of all our acquisitions, like ACD, has gone well and we look forward to applying our strong cash flow to more acquisitions in the future. Teams from all three global divisions have done an exceptional job this year in creating synergies as we integrate and leverage strong commercial cross selling to our academic and Biopharma customers. Europe, as one example, had 11 percent organic growth for the year, capitalizing on fabulous teamwork across the countries.”

Kummeth concluded, “Bio-Techne is creating an extraordinary image in the industry, focusing on uncompromising service and quality to our loyal customers. I want to thank all our employees worldwide and wish them well as we move into fiscal year 2018.”

Segment Results

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

Biotechnology Segment

The Company’s Biotechnology segment includes proteins, antibodies, immunoassays, flow cytometry products, intracellular signaling products, and biologically active chemical compounds used in biological research, as well as ACD’s in situ hybridization detection products. Biotechnology segment’s fourth quarter fiscal 2017 net sales were $97.2 million, an increase of 15% from $84.4 million for the fourth quarter of fiscal 2016. Organic growth for the segment was 2%, with currency translation having an unfavorable impact of 1% on revenue growth and acquisitions contributing 14% to revenue growth. Biotechnology segment’s adjusted operating margin was 49.3% in the fourth quarter of fiscal 2017 compared to 52.4% in the fourth quarter of fiscal 2016. The lower adjusted operating margin is the result of recent acquisitions, namely ACD, made in this segment.

Organic growth for the segment was 4% for the fiscal year, with currency translation having an unfavorable impact of 2% on revenue growth. Biotechnology segment’s adjusted operating margin was 48.1% in full fiscal year 2017 compared to 53.1% in fiscal 2016. The lower adjusted operating margin is largely the result of recent acquisitions, namely ACD, made in this segment.

The Protein Platforms segment’s adjusted operating margin was 16.2% in the fourth quarter of fiscal 2017 compared to 7.5% in the fourth quarter of fiscal 2016.

Protein Platforms segment’s organic revenue increased 19%, with an unfavorable currency impact of 2% and acquisitions contributing 1% to revenue growth.

Use of 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 and certain adjustments to income tax expense. Stock based compensation is excluded from non-GAAP adjusted earnings because of the nature of this charge, specifically the varying available valuation methodologies, subjective assumptions, and the variety of award types. 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.

GAAP PURCHASE ACCOUNTING ITEMS

(In thousands)

(Unaudited)

During the fourth quarter, management identified certain errors related to purchase accounting items for the ACD acquisition recorded during the first quarter of fiscal year 2017. These items impact the cost recognized upon the sale of acquired inventory, other acquisition related costs recorded within selling, general and administrative costs, and income taxes and resulted in a favorable impact to previously reported quarterly results as outlined in the table below.

We concluded that these errors were not material to each of the respective periods; however, we have elected to report the corrected amount for the fourth quarter and will revise the previously reported 2017 information in future filings to reflect the properly stated amounts. These identified items have no impact to year to date GAAP results. Additionally, there is no impact to quarterly or year to date reported non-GAAP results.
