“Patterson’s fourth quarter and fiscal 2019 results reflect continued top line growth and improved profitability trends throughout the year, enabling us to deliver on our earnings expectations while making continued necessary investments in our people, technology and services,” said Mark Walchirk, President and CEO of Patterson Companies. “Through the execution of our strategic priorities, we have successfully stabilized our core business and returned both of our segments to growth. We continued to drive strong performance in both the companion and production animal businesses, and we achieved our second consecutive quarter of year-over-year revenue growth in Dental, fueled by strong growth across the equipment category. We are pleased with Patterson’s performance during the first full year of our three-year plan, and we are positioned to build momentum behind our improved performance going forward.”

The fiscal 2018 period included the recognition of a provisional tax benefit of $76.6 million, reflecting the revaluation of tax-deferred assets and liabilities, net of a one-time transition tax on unremitted foreign earnings as a result of the 2017 Tax Act. In July 2018, Patterson Companies booked a pre-tax reserve of $28.3 million for the settlement of certain purported class action antitrust litigation.

Adjusted net income¹ attributable to Patterson Companies, Inc. for fiscal 2019, which excludes deal amortization costs, integration and business restructuring costs, legal reserve costs and discrete tax matters, totaled $130.9 million, or $1.40 per diluted share, compared to adjusted net income of $156.8 million, or $1.68 per diluted share, in fiscal 2018.

FY2020 Guidance

Patterson Companies today announced its fiscal 2020 earnings guidance, which is provided on both a GAAP and non-GAAP adjusted¹ basis:

• GAAP earnings are expected to be in the range of $0.99 to $1.09 per diluted share.

• Non-GAAP adjusted earnings¹ are expected to be in the range of $1.33 to $1.43 per diluted share.

• Our non-GAAP adjusted earnings¹ guidance excludes the after-tax impact of:

• Deal amortization expenses of approximately $28.7 million ($0.32 per diluted share).

• Integration and business restructuring expenses of approximately $1.4 million ($0.02 per diluted share).

Our guidance is for current operations as well as completed or previously announced acquisitions and does not include the impact of potential future acquisitions or similar transactions, if any, or impairments and material restructurings beyond those previously publicly disclosed. Our guidance assumes North American and international market conditions similar to those experienced in fiscal 2019.

¹Non-GAAP Financial Measures

The Reconciliation of GAAP to non-GAAP Measures table appearing behind the accompanying financial information is provided to adjust reported GAAP measures, namely operating income, income before taxes, income tax expense, net income, net income attributable to Patterson Companies, Inc. and diluted earnings per share attributable to Patterson Companies, Inc., for the impact of deal amortization, integration and business restructuring expenses, legal reserve costs and discrete tax matters, along with the related tax effects of these items.

Management believes that these non-GAAP measures may provide a helpful representation of the company’s fourth-quarter performance and earnings guidance, and enable comparison of financial results between periods where certain items may vary independent of business performance. These non-GAAP financial measures are presented solely for informational and comparative purposes and should not be regarded as a replacement for corresponding, similarly captioned, GAAP measures.

In addition, the term “internal sales” used in this release represents net sales adjusted to exclude foreign currency impact and changes in product selling relationships. Foreign currency impact represents the difference in results that is attributable to fluctuations in currency exchange rates the company uses to convert results for all foreign entities where the functional currency is not the U.S. dollar. The company calculates the impact as

PATTERSON COMPANIES | 1031 Mendota Heights Road | Saint Paul, MN 55120 NEWS RELEASE

the difference between the current period results translated using the current period currency exchange rates and using the comparable prior period’s currency exchange rates. The company believes the disclosure of net sales changes in constant currency provides useful supplementary information to investors in light of significant fluctuations in currency rates.

Investors can listen to a live webcast of the conference call at www.pattersoncompanies.com. The conference call will be archived on the Patterson Companies website.
