BIO-TECHNE RELEASES FOURTH QUARTER FISCAL 2018 RESULTS

Minneapolis/August 7, 2018/ Bio-Techne Corporation (NASDAQ:TECH) today reported its financial results for the fourth quarter ended June 30, 2018.

Fourth Quarter and Full Year FY2018 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.

“Our team delivered an exceptional quarter to top off a record year for our company,” said Chuck Kummeth, President and Chief Executive Officer of Bio-Techne. “Not only did we achieve 9% organic growth for the quarter, but we did for the entire year as well. My congratulations to the entire global Bio-Techne team now totaling over 2100 strong.”

Kummeth added, “We are well positioned in our end-markets and are accelerating in our momentum to innovate best-in-class products for our customers which include those in the fields of research, diagnostics and therapeutics. Our recent acquisitions of Quad Technologies and ExosomeDx give us even more runway into the growing and scalable markets of Cell Therapy and Cancer Diagnostics, markets that already know our brands for research reagents and tools.”

Kummeth concluded, “Our Advanced Cell Diagnostics platform finished the year with over 30% organic growth and we expect more growth from this very exciting diagnostic technology. And very soon, we are hopeful that Medicare will approve reimbursement for ExoDx® Prostate IntelliScore (EPI), a urine-based test, to assist physicians in determining the need for a prostate biopsy in patients with an ambiguous PSA test result. Medicare approval will support a rapid adoption for this exciting and game changing technology platform that improves patient care.”

Fourth Quarter Fiscal 2018

Revenue

Net sales for the fourth quarter increased 15% to $180.3 million. Organic growth was 9% compared to the prior year, with currency translation having a positive impact of 2% and acquisitions contributing 4% to revenue growth.

GAAP Earnings Results

GAAP EPS increased to $1.07 per diluted share, versus $0.74 in the same quarter last year. GAAP EPS was favorably impacted by gains on the partial sale of the Company’s stock investment in CCXI. GAAP operating income for the fourth quarter of fiscal 2018 increased 7% to $42.9 million, compared to $40.0 million in the fourth quarter of fiscal 2017. GAAP operating margin was 23.8%, compared to 25.6% in the fourth quarter of fiscal 2017. GAAP operating margin compared to prior year was negatively impacted by additional stock compensation expense recognized as a result of a new retirement policy that permits retirees to continue vesting in certain time-based stock options granted during employment, resulting in accelerated stock compensation expense for those employees meeting the definition of retirement eligible.

Non-GAAP Earnings Results

Adjusted EPS increased to $1.34 per diluted share, versus $1.09 in the same quarter last year. Adjusted operating income for the fourth quarter of fiscal 2018 increased 18% compared to the same quarter last year. Adjusted operating margin was 39.5%, compared to 38.7% in the fourth quarter of fiscal 2017. Adjusted operating margin compared to the prior year was positively impacted by strong volume leverage.

Full Year Fiscal 2018

Revenue

Net sales for the full year fiscal 2018 increased 14% to $643.0 million. Organic growth was 9% compared to the prior year, with currency translation having a positive impact of 2% and acquisitions contributing 3% to revenue growth.

GAAP Earnings Results

GAAP EPS increased to $3.29 per diluted share, versus $2.03 in fiscal 2017. GAAP operating income increased 13% to $136.2 million, compared to $120.6 million in fiscal 2017. GAAP operating margin was 21.2%, compared to 21.4% in fiscal 2017. GAAP operating margin compared to prior year was negatively impacted by additional stock compensation expense and costs associated with recent acquisitions, as well as investments in global commercial resources and administrative infrastructure.

Non-GAAP Earnings Results

Adjusted EPS increased to $4.54 per diluted share, versus $3.72 in fiscal 2017. Adjusted operating income for fiscal 2018 increased 15% compared to fiscal 2017. Adjusted operating margin was 37.1%, compared to 37.0% in fiscal 2017. Adjusted operating income compared to prior year was positively impacted by strong volume leverage, which was offset by negative business mix, lower margin acquisitions, and investments in global commercial resources and administrative infrastructure.

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

Biotechnology segment’s adjusted operating margin was 48.1% in the fourth quarter of fiscal 2018 compared to 49.1% in the fourth quarter of fiscal 2017.

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, gains and losses from investments, 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. Impairments of equity investments are excluded as we do not have significant influence over these investments and 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.
