PATTERSON COMPANIES REPORTS FISCAL 2025

FIRST QUARTER OPERATING RESULTS

• First quarter reported net sales decreased 2.2 percent year-over-year to $1.54 billion, and internal sales decreased 2.8 percent.

• Returned $73.3 million to shareholders in first quarter of fiscal 2025 through dividends and share repurchases.

• Delivered first quarter GAAP earnings of $0.15 per diluted share and adjusted earnings¹ of $0.24 per diluted share; both GAAP and adjusted earnings¹ were negatively impacted by the cybersecurity attack on Change Healthcare compared to the prior year.

• Reaffirms fiscal 2025 GAAP earnings guidance range of $2.00 to $2.10 per diluted share and adjusted earnings¹ guidance range of $2.33 to $2.43 per diluted share.

St. Paul, Minn. — August 28, 2024 — Patterson Companies, Inc. (Nasdaq: PDCO) today reported operating results for its fiscal 2025 first quarter ended July 27, 2024.

“Our first quarter results fell short of our expectations, primarily due to the greater than anticipated impact of the Change Healthcare cybersecurity attack on the value-added services category in our dental segment, along with lower sales in our companion animal business and the timing of certain corporate expenses,” said Don Zurbay, President and CEO of Patterson Companies. “In light of these factors and against the backdrop of a challenging macroeconomic environment, we are taking dedicated cost and management actions across Patterson to deliver on our financial plan for fiscal 2025, and maintaining a strategic focus on supporting our customers with the deep and differentiated value-proposition they expect from us.”

First Quarter Fiscal 2025 Results

Consolidated net sales were $1.54 billion (see attached Sales Summary for further details), a decrease of 2.2 percent compared to the same period last year. Internal sales, which are adjusted for the effects of currency translation and the net impact of an interest rate swap, decreased 2.8 percent over the prior year period.

Reported net income attributable to Patterson Companies, Inc. for the first quarter of fiscal 2025 was $13.7 million, or $0.15 per diluted share, compared to $31.2 million, or $0.32 per diluted share, in the first quarter of fiscal 2024. Adjusted net income¹ attributable to Patterson Companies, Inc., which excludes deal amortization totaled $21.0 million for the first quarter of fiscal 2025, or $0.24 per diluted share, compared to $38.6 million, or $0.40 per diluted share, in the first quarter of fiscal 2024. The year-over-year decrease in reported and adjusted net income attributable to Patterson Companies, Inc. in the first quarter of fiscal 2025 is related to lower retail sales and operating margins in both business segments and the continued negative impact of the widely reported cybersecurity attack on vendor Change Healthcare, within the value-added services category of the dental segment. Both reported and adjusted net income in the fiscal 2025 first quarter were negatively impacted by the cybersecurity attack on Change Healthcare compared to the prior year period.

Patterson Dental

Reported net sales in the Dental segment for the first quarter of fiscal 2025 were $550.4 million. Internal sales decreased 2.8 percent compared to the fiscal 2024 first quarter. Internal sales of consumables decreased 2.1 percent year-over-year. Excluding the deflationary impact of certain infection control products, internal sales of consumables decreased 1.7 percent year-over-year. Compared to the prior year period, internal sales of equipment decreased 2.4 percent. Internal sales of value-added services decreased 6.7 percent compared to the prior year period, primarily due to the negative impact of the cybersecurity attack on Change Healthcare.

Patterson Animal Health

Reported net sales in the Animal Health segment for the first quarter of fiscal 2025 were $982.4 million. Internal sales declined 2.8 percent compared to the fiscal 2024 first quarter.

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

Compared to the prior year period, internal sales of consumables declined 3.0 percent, equipment decreased 3.8 percent and value-added services increased 8.3 percent.

Balance Sheet and Capital Allocation

During the first quarter of fiscal 2025, Patterson Companies used $285.0 million of cash from operating activities and collected deferred purchase price receivables of $271.8 million, using $13.1 million in cash, compared to using $11.4 million during the first quarter of fiscal 2024. Free cash flow¹ (see definition below and attached free cash flow table) during the first quarter of fiscal 2025 improved by $1.8 million compared to the first quarter of fiscal 2024.

In the first quarter of fiscal 2025, Patterson Companies declared a quarterly cash dividend of $0.26 per share, returning $23.3 million in cash dividends to shareholders. Also, under a prior repurchase authorization, the company repurchased approximately $50.0 million of shares during the fiscal first quarter. At of the end of the first quarter of fiscal 2025, Patterson had approximately $450 million of share repurchase authority remaining on its current share repurchase authorization. During the first quarter of fiscal 2025, Patterson Companies returned $73.3 million to shareholders in the form of cash dividends and share repurchases.

Fiscal 2025 Guidance

Patterson Companies today reaffirmed its fiscal 2025 earnings guidance, which is provided on both a GAAP and non-GAAP adjusted¹ basis:

● GAAP earnings are expected to be in the range of $2.00 to $2.10 per diluted share.

● Non-GAAP adjusted earnings¹ are expected to be in the range of $2.33 to $2.43 per diluted share.

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

 - Deal amortization expenses of approximately $29.1 million ($0.33 per diluted share).

Our guidance reflects the strength of our business and competitive positioning as well as completed and previously announced acquisitions. It does not include the impact of unplanned share repurchases, potential future acquisitions or similar transactions, impairments, restructuring and integration expenses not previously publicly disclosed, or amortization expense of acquired intangible assets. Our guidance assumes North American and international end market conditions consistent with current market conditions.

¹Non-GAAP Financial Measures

The term “internal sales” used in this release represents net sales adjusted for the effects of currency translation and the net impact of an interest rate swap. 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 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 excluding the impact of foreign currency and an interest rate swap provides useful supplementary information to investors in light of fluctuations in these variables that are independent of our period-over-period performance.

The term “free cash flow” used in this release is defined as net cash used in operating activities less capital expenditures plus the collection of deferred purchase price receivables.

The Reconciliation of GAAP to non-GAAP Measures table appearing behind the accompanying financial information is provided to adjust reported GAAP measures, namely net sales, gross profit, operating expenses, operating income, other income (expense), net, income before taxes, income tax expense, net income, net loss attributable to noncontrolling interests, net income attributable to Patterson Companies, Inc., and diluted earnings per share attributable to Patterson Companies, Inc. for the impact of deal amortization and an interest rate swap along with any related tax effects of these items.

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

● Deal amortization represents non-cash intangible amortization expense, primarily related to the acquisition of Animal Health International.

● Interest rate swap — Our customer financing net sales include the impact of changes in interest rates on deferred purchase price receivables, as the average interest rate in our contract portfolio may not fluctuate at the same rate as interest rate markets, resulting in an increase or reduction of gain on contract sales.

We enter into an interest rate swap to hedge a portion of the related interest rate risk. These agreements do not qualify for hedge accounting, and the gains or losses on an interest rate swap are reported in other income and expense in our condensed consolidated statements of operation and other comprehensive income.

We present a non-GAAP adjustment to reclassify the mark-to-market adjustment on the interest rate swap from other income (expense) to net sales to align the swap impact with the impact on customer financing net sales. We believe adjusted net sales, adjusted gross profit and adjusted operating income, which include the gains and losses on the interest rate swap, provides additional comparability from period to period because they present the impact of interest rate fluctuations, net of the mark-to-market swap adjustment, within adjusted net sales. We note the net impact of interest rate fluctuations has a minimal impact on net income.

Management believes that these non-GAAP measures may provide a helpful representation of the company’s performance 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.
