To Our Shareholders

Patterson  was  solidly  profitable  in  fiscal  2009,  but 
there is no mistaking the fact that the past year was a 
challenging period as we coped with the impact of the 
recession on the purchasing decisions of customers 
at  each  of  our  businesses.  Despite  this  difficult 
operating  environment,  we  capitalized  upon  our 
strong financial condition and operating cash flows to 
transact several acquisitions that have strengthened 
the competitive positions of our businesses. We are 
continuing to make strategic investments in programs 
and  initiatives  aimed  at  bolstering  our  sales  and 
profitability.  Although  the  weak  economy  will  likely 
continue  to  affect  our  near-term  performance,  we 
believe the actions that we are taking today will help 
assure a successful long-term future for Patterson.

For the fiscal year ended April 25, 2009, consolidated 
sales totaled $3,094,227,000. This was up 3% from 
$2,998,729,000 in fiscal 2008. Revenue growth was 
positively impacted by several acquisitions during the 
past fiscal year, but was negatively affected by foreign 
currency exchange movements during the second half. 
Net income for the year came to $199,635,000 or 
$1.69 per diluted share, compared to $224,858,000 
or  $1.69  per  diluted  share  in  fiscal  2008.  Profits 
were reduced as a result of the weakening economic 
conditions and increased debt levels. Our per share 
earnings reflect the impact of our share repurchasing 
activity during the second half of fiscal 2008.

We acted to reduce our operating costs to better align 
our expense structure with revenues in fiscal 2009 
and  with  our  anticipated  performance  in  2010. 
These  measures  included  company-wide  salary 
reductions, a hiring freeze except for sales personnel, 
and restrictions on travel and other more discretionary 
spending.  We  are  prepared  to  take  additional  cost 
control  measures,  as  necessary,  to  maintain  our 
operating margin in fiscal 2010 at a level consistent 
with 2009.

> Patterson Dental
Sales of Patterson Dental supply came to $2.2 billion 
in  fiscal  2009,  virtually  unchanged  from  the  prior 
year.  Although  dental  practitioners  as  a  whole  are 
continuing to prosper amid the recession and patient 
loads  remain  strong,  sales  of  consumable  dental 
supplies have been affected by patients electing to 
defer  higher-level  and  discretionary  services.  While 
the recession affected equipment sales at each of our 

businesses, customer caution was particularly evident 
in  reduced  sales  of  basic  dental  equipment.  This 
drop was particularly significant in the fourth quarter. 
Partly  offsetting  this  decline  were  growing  sales  of 
the  CEREC®  dental  restorative  product  line  and 
digital radiography systems. We believe the recession 
is  causing  many  dental  practitioners  to  focus  on 
equipment purchases that yield rapid rates of return 
that  can  measurably  improve  their  productivity  and 
profitability. New technology products like CEREC and 
digital X-ray systems  meet this return on investment 
requirement. We believe digital sales are also benefiting 
from changes to Patterson Dental’s operating model, 
that  include  providing  our  proprietary  EagleSoft® 
practice  management  software  to  customers  at  no 
charge  and  revising  our  commission  structure.  In 
December 2008, we further strengthened Patterson 
Dental’s  position  as  the  leading  distributor  of  new-
technology equipment by acquiring Dolphin Imaging 
Systems,  LLC  and  Dolphin  Practice  Management, 
LLC, the world’s leading provider of 3D imaging and 
practice management software for specialized dental 
practitioners.

> Webster Veterinary 
Webster,  the  nation’s  second  largest  distributor  of 
companion-pet veterinary supplies, posted fiscal 2009 
sales of $551 million, up from $446 million in 2008. 
This growth was due primarily to the October 2008 
acquisition of Columbus Serum Company. Excluding 
the impact of Columbus Serum, veterinary sales were 
up 4%, reflecting the economy-related slowdown in 
activity at veterinary clinics. Columbus Serum is a full 
service  distributor  that  primarily  serves  companion-
pet  veterinarians  in  the  Midwest  and  mid-Atlantic 
regions. During the past year, Webster also continued 
to refine and expand its relatively new equipment and 
software business, which represents a key component 
of  Webster’s  drive  to  strengthen  its  value-added 
platform. Webster is now selling equipment in most 
of  its  markets,  an  initiative  supported  by  the  unit’s 
expanding capabilities in local technical support and 
financing.

> Patterson Medical
Patterson  Medical,  the  world’s  leading  distributor 
of  rehabilitation  supplies  and  equipment,  reported 
modestly lower sales of $369 million in fiscal 2009. 
The past year’s sales were affected by the impact of 
the stronger U.S. dollar on Patterson Medical’s U.K. 

2

operation and the effect of the weak economy 
on  sales  of  rehabilitation  equipment.  In 
April  2009,  Patterson  Medical’s  U.K.  unit, 
Homecraft  Rolyan  Ltd.,  acquired  Mobilis 
Healthcare  Group,  one  of 
the  U.K.’s 
leading  value-added  distributors  of  physical 
therapy,  sports  medicine  and  podiatry 
products. Patterson Medical also focused on 
strengthening the operations of its 12 branch 
offices around the U.S. As part of this effort, 
these  branches  completed  their  cutover 
to  Patterson’s  systems  platform.  Patterson 
Medical is continuing to invest in operating 
systems that will enable it to accelerate growth 
and gain additional economies of scale.

and 

> Looking Ahead
The  long-term  fundamentals  of  the  dental, 
rehabilitation  markets 
veterinary 
are  strong.  Our  businesses  hold  strong 
competitive positions in their markets due to 
their  full-service,  single-source  capabilities 
and  established  reputations  for  quality 
service.  We  have  implemented  aggressive 
marketing programs at each of our operating 
units to mitigate the continuing impact of the 
soft economy. In addition, we are generating 
sizeable  cash  flow  from  our  operations, 
providing  us  with  ample  resources  for 
supporting  our  various  growth  initiatives. 
Given  these  factors,  we  are  confident  that 
Patterson’s future remains secure.

As always, we are grateful for the dedicated efforts of 
our many outstanding employees. We also appreciate 
the  continued  support  of  our  shareholders,  valued 
customers, and vendor business partners.

Patterson	 Dental,	 one	 of	 North	 America’s	 largest	
value-added	 dental	 distributors,	 serves	 its	 large	
customer	base	through	a	highly	developed	single-
source,	 full-service	 strategy.	 A	 virtually	 complete	
range	 of	 consumable	 supplies,	 equipment	 and	
value-added	 services	
is	 provided	 through	 the	
industry’s	 largest	 sales	 force,	 operating	 out	 of	 an	
extensive	branch	office	network	spanning	the	U.S.	
and	Canada.	The	quality,	timeliness	and	scope	of	our	
services	are	unsurpassed.

Patterson Dental

The	growing	interest	in	CEREC	systems	has	gained	
momentum	over	the	past	two	years	due	to	a	more	
focused	 marketing	 effort	 and	 the	 introduction	
of	 important	 product	 enhancements	 by	 CEREC’s	
manufacturer,	 Sirona	 Dental	 Systems,	 Inc.	 Early	 in	
calendar	 year	 2007,	 Sirona	 introduced	 enhanced	
software	 and	 a	 more	 robust	 milling	 chamber	 for	
its	 CEREC	 products.	 Then	 in	 January	 2009,	 Sirona	
unveiled	 a	 new	 digital	 impression	 unit,	 called	
CEREC	AC,	which	uses	proprietary	technology	that	
gives	practitioners	increased	speed,	
unprecedented	 levels	 of	 precision,	
full-arch	 imaging	 and	 significantly	
greater	 ease	 of	 use.	 This	 next-
generation	technology	also	enables	
scaleable	 pricing,	 making	 CEREC’s	
CAD/CAM	technology	practical	for	a	larger	number	
of	practitioners.		

To	 further	 strengthen	 its	 position	 in	 the	 field	 of	
dental	 technology,	 Patterson	 Dental	 acquired	
Dolphin	Imaging	Systems,	LLC	and	Dolphin	Practice	
Management,	 LLC	 in	 fiscal	 2009.	 Dolphin	 is	 the	
world’s	leading	provider	of	3D	imaging	and	practice	
management	 software	 for	 specialized,	 high-end	
dental	 practitioners,	 including	 orthodontists,	 oral	
maxillofacial	surgeons	and	dental	radiologists.	

Dolphin	 provides	 two	 industry-leading	 lines	 of	
proprietary	dental	software	and	related	services:

>	Its	imaging	software	maximizes	the	benefits	of	
cone	beam	and	other	digital	photography	and	
radiography	systems	by	enabling	practitioners	to	
electronically	 capture,	 manipulate	 and	 analyze	
imaging	records;	perform	diagnosis	and	advanced	
2D	and	3D	visualization;	and	graphically	simulate	
treatment	outcomes.	Dolphin’s	products	support	
most	 cone	 beam	 systems,	 digital	 radiography	
systems,	2D	and	3D	digital	photographic	systems,	
and	 picture	 archiving	 and	 communications	
systems.	

>	Dolphin’s	orthodontic	
practice	management	
software	manages	
workflows,	patient	
scheduling	and	
financial	systems.

Aligning	 Dolphin	 with	
our	Patterson	Technology	
Center	 will	 differentiate	
the	Dolphin	and	Patterson	
brands	
in	 the	 dental	
marketplace.

The	next-generation	CEREC	dental	restorative	system	
incorporates	a	new	digital	impression	unit,	called	
CEREC	AC,	which	uses	proprietary	technology	that	gives	
practitioners	increased	speed,	unprecedented	levels	of	
precision,	full-arch	imaging	and	significantly	greater	
ease	of	use.	

Patterson	is	North	America’s	leading	distributor	of	
new-technology	 equipment,	 which	 has	 become	 a	
key	 component	 of	 modern	 dentistry.	 We	 are	 the	
exclusive	North	American	distributor	of	the	CEREC	
dental	 restorative	 system,	 the	 most	 advanced	 and	
best	selling	CAD/CAM	system	on	the	market	today.	
We	also	are	the	exclusive	North	American	distributor	
of	Schick	sensors,	which	are	used	in	the	majority	of	
all	digital	x-ray	installations.	Both	CEREC	and	digital	
x-ray	 systems	 provide	 improved	 outcomes,	 while	
measurably	strengthening	dental	office	productivity	
and	profitability	by	enabling	practitioners	to	handle	
growing	 patient	 loads.	 Given	 the	 rapid	 rates	 of	
return	on	this	equipment,	dentists	are	continuing	to	
invest	in	these	technologies	amid	a	weak	economy.

through	 a	 combination	 of	 internal	 growth	 and	
strategic	acquisitions.	The	growth	and	value-added	
development	of	Webster	took	a	major	step	forward	
in	fiscal	2009	with	the	acquisition	of	Columbus	Serum	
Company,	a	full-service,	value-added	distributor	of	
veterinary	 products.	 Serving	 veterinarians	 in	 the	
Midwest	and	mid-Atlantic	regions,	Columbus	Serum	
has	significantly	strengthened	Webster’s	competitive	
position	in	these	markets.

Headquartered	in	Columbus,	Ohio,	Columbus	Serum	
has	 established	 a	 strong	 reputation	 for	 customer	
service	 and	 a	 substantial	 presence	 in	 its	 regional	
markets	over	the	past	eight	decades.	The	company	
serves	its	customers	through	more	than	60	territory	
sales	representatives	and	over	50	in-house	customer	
service	 representatives.	 Opportunities	 exist	 to	
leverage	the	distribution	centers	and	sales	offices	of	
the	combined	businesses.

As	 part	 of	 its	 plan	 to	 strengthen	 its	 full-service	
platform,	 Webster	 is	 continuing	 to	 refine	 and	
expand	its	veterinary	equipment	business.	Webster	
is	now	selling	a	growing	range	of	equipment	and	
software,	 including	 digital	 x-ray	 systems,	 tables,	
kennels,	 and	 cabinetry,	 in	 most	 of	 its	 markets.	
Webster	 is	 supporting	 this	 initiative	 through	 its	
steadily	 expanding	 capabilities	 in	 financing	 and	
local	technical	service.	In	addition,	several	Webster	
branches	include	equipment	showrooms.

Webster	acquired	Odyssey	Veterinary	Software	LLC	in	fiscal	
2009,	an	early	stage	developer	and	marketer	of	Diagnostic	
Imaging	Atlas	software	(DIA)	that	enables	veterinarians	
to	more	fully	explain	and	illustrate	a	pet’s	diagnosis	and	
recommended	treatment.

The	 companion-pet	 market	 is	 the	 fastest	 growing	
segment	of	the	overall	veterinary	supply	market.	Pet	
ownership	is	continuing	to	grow	steadily,	and	pet	
owners	are	willing	to	spend	more	on	veterinary	care	
for	pets	they	consider	to	be	a	part	of	the	family.	To	
capitalize	on	these	trends	and	enable	veterinarians	
to	increase	their	productivity	and	revenues,	Webster	
serves	 its	 customers	 as	
a	 value-added,	 single-
source	 of	 supply.	 Today,	
Webster	
the	
industry’s	 widest	 choice	
of	 consumable	 supplies	
and	 equipment.	 Nearly	
240	sales	representatives	working	out	of	15	branch	
offices	constitute	a	business	partner	that	delivers	the	
full	range	of	Webster’s	products	and	
services.	This	customer	relationship	
is	 enhanced	 by	 a	 network	 of	
specialized	equipment,	technology	
and	equine	representatives.

The growth of the estimated 
$6 billion rehabilitation market 
is being fueled by the aging 
baby boomer population, 
growing numbers of sports and 
recreation-related injuries, and 
medical treatments that involve 
a rehabilitation protocol for the 
recovery process.

Over	 the	 past	 few	 years,	
Patterson	 Medical	
has	
focused	 on	 developing	 its	
value-added	
full-service,	
platform.	 Today,	 it	 offers	
a	 virtually	 complete	 range	
of	
supplies	
and	 equipment,	 delivered	
through	more	than	200	sales	
representatives	 worldwide	
and	a	large	catalog	operation.	Through	acquisitions	
and	
internal	 start-ups,	 Patterson	 Medical	 has	
established	 a	 branch	 office	 structure	 that	 now	
consists	of	12	branches	around	the	U.S.	that	share	a

therapy	market.	In	this	way,	Mobilis	provides	
a	 new	 customer	 base	 for	 our	 international	
rehabilitation	 supply	 business.	 Mobilis	 also	
serves	as	a	platform	for	Homecraft’s	expansion	
into	the	sports	medicine	market.

The	 growth	 of	 the	 estimated	 $6	 billion	
rehabilitation	 market	 is	 being	 fueled	 by	 a	
combination	of	factors,	including	the	aging	
baby	 boomer	 population.	 The	 U.S.	 Census	
Bureau	 estimates	 that	 the	 population	 over	
the	 age	 of	 65	 will	 double	 in	 size	 between	
2000	and	2030,	growing	from	35	million	to	
72	 million.	 Aging	 population	 trends	 in	 the	
U.K.	closely	mirror	those	in	the	U.S.	Growing	
demand	for	rehabilitation	services	also	is	being	
generated	 by	 today’s	 more	 active	 lifestyles,	
resulting	in	growing	numbers	of	sports	and	
recreation-related	injuries.	In	addition,	there	
is	 a	 trend	 toward	 less	 invasive	 treatment	
and	 intervention,	 which	 frequently	 involves	
a	 rehabilitation	 protocol	 for	 the	 recovery	
process.	Through	its	full-service,	value-added	
capabilities,	Patterson	Medical	is	well	positioned	to

PART I

Certain information of a non-historical nature contained in Items 1, 2, 3 and 7 of this Form 10-K includes

forward-looking statements. Reference is made to Item 7—Management’s Discussion and Analysis of Financial
Condition and Results of Operations—Factors that May Affect Future Operating Results, for a discussion of
certain factors that could cause the Company’s actual operating results to differ materially from those expressed
in any forward-looking statements.

General

In June 2004, the Company changed its corporate name from Patterson Dental Company to Patterson
Companies, Inc. (“Patterson” or the “Company”). Patterson retained its existing Nasdaq stock symbol—PDCO.
The corporate name change was adopted to reflect Patterson’s expanding base of business, which now
encompasses the veterinary and rehabilitation supply markets, as well as its traditional base of operations in the
dental supply market. Patterson’s operating units include Patterson Dental, Webster Veterinary and Patterson
Medical.

Patterson is a value-added distributor serving three major markets:

• North American dental supply;

• U.S. companion-pet (dogs, cats and other common household pets) and equine veterinary supply;

• And the worldwide rehabilitation and assistive products supply market.

Unless otherwise indicated, all references to Patterson or the Company include its subsidiaries: Patterson
Dental Holdings, Inc., Direct Dental Supply Co., Patterson Dental Canada Inc., Patterson Dental Supply, Inc.,
Webster Veterinary Supply, Inc., PDC Funding Company, LLC, PDC Funding Company II, LLC, Patterson
Technology Center, Inc., Patterson Office Supplies, Inc., Webster Management LP, Patterson Medical Holdings,

Archway Distribution Inc., Arco Dental Inc., Provi-Modern Medical International Inc. Columbus Serum
Company, CSC High Plains, LLC, CSC South, LLC, Dolphin Imaging Systems, LLC, Dolphin Practice
Management, LLC and Kinetec SA.

Patterson began distributing dental supplies in 1877. The modern history of the business dates to May 1985,

when the Company’s management and certain investors purchased the Company from a subsidiary of The
Beatrice Companies, Inc. Patterson became a publicly traded company in October 1992. The Company is a
corporation organized under the laws of the state of Minnesota.

The Company historically reported one operating segment, dental supply. In July 2001, the Company
purchased the veterinary supply assets of J. A. Webster, Inc., which became a reportable business segment. Then
in September 2003, the Company acquired AbilityOne Products Corp., creating a third business segment which
serves the rehabilitation supply market.

The Company’s three reportable segments, dental supply, veterinary supply and rehabilitation supply, are
strategic business units that offer similar products and services to different customer bases. Each business is a
market leader with a strong competitive position, serves a fragmented market that offers consolidation
opportunities and offers relatively low-cost consumable supplies, making the Company’s value-added business
proposition highly attractive to customers.

3

Shared Services Initiative

The Company has continued to consolidate its distribution infrastructure and business systems over the past

several years. With respect to the distribution infrastructure, beginning in fiscal 2005, the consolidation of
facilities began with a facility in Columbia, SC that replaced the individual dental and veterinary distribution
centers that were serving this region. As of April 25, 2009, there are seven facilities that serve two or three of the
Company’s business units. These strategically located facilities enable the Company to realize operating
efficiencies and improve customer service.

In fiscal 2008, the first shared sales branch office locations were established, enabling multiple business

units to operate at one physical location. As of April 25, 2009, there are four shared locations and the Company
plans to leverage additional branch sharing between two or three business units in select markets in fiscal 2010
and beyond.

The Patterson Technology Center (“PTC”) has staff dedicated to the support of the technology offerings of

each of the Company’s business units. Such technology product and service offerings have expanded in recent
years and will continue to be a focus of the Company. The PTC supports over 45,000 customers nationwide, with
a goal to resolve any situation in one call, whether the question or concern involves hardware, software,
computer networking or digital technology. In addition, the PTC provides network installation, customer training
and develops customer order entry systems for the Company’s businesses.

Dental Supply

Overview

As Patterson’s largest business, Patterson Dental is one of the two largest distributors of dental products in

North America. The business has operations in the United States and Canada. Patterson Dental, a full-service,
value-added supplier to dentists, dental laboratories, institutions, and other healthcare professionals, provides:
consumable products (including x-ray film, restorative materials, hand instruments and sterilization products);
basic and advanced technology dental equipment; practice management and clinical software; patient education
systems; and office forms and stationery. Patterson Dental offers its customers a broad selection of dental
products including more than 90,000 stock keeping units (“SKUs”) of which approximately 4,000 are private-
label products sold under the Patterson name. Patterson Dental also offers customers a full range of related
services including dental equipment installation, maintenance and repair, dental office design and equipment
financing. Patterson Dental markets its dental products and services through approximately 1,500 direct sales
representatives, 279 of whom are equipment specialists.

Patterson Dental has over 125 years of experience providing quality service to dental professionals. Net
sales of this segment have increased from $165.8 million in fiscal 1986 to approximately $2.2 billion in fiscal
2009 and profitability has increased from an operating loss in fiscal 1986 to operating income of $264.5 million
in fiscal 2009.

Patterson estimates the dental supply market it serves to be approximately $6.8 billion annually and that its

share of this market is approximately 32%. The underlying structure of the dental supply market consists of a
sizeable geographically dispersed number of fragmented dental practices and is attractive for the Company’s role
as a value-added, full-service distributor. According to the American Dental Association, there are over 170,000
dentists practicing in the United States. In Canada, there are approximately 19,000 licensed dentists according to
the Canadian Dental Association. The average general practitioner generated approximately $670,000 in annual
revenue in 2006, while the average specialty practitioner produces about $925,000. The Company believes that a
dentist uses between 5% and 7% of annual revenue to purchase consumable supplies used in the daily operations
of the practice. This translates into between $33,000 and $47,000 of supplies being purchased by the average
practice each year. The Company believes the average dental practitioner purchases about 40% of their supplies
from their top supplier.

4

Total expenditures for dental services in the United States increased from $31 billion in 1990 to $95 billion
in 2007. The Company believes that the demand for dental services, equipment and supplies will continue to be
influenced by the following factors:

• Demographics. The U.S. population grew from 235 million in 1980 to 305 million in 2008, and is

expected to reach 325 million by 2015. The median age of the population is also increasing and the
Company believes that older dental patients spend more on a per capita basis for dental services.

• Dental products and techniques. Technological developments in dental products have contributed to
advances in dental techniques and procedures, including cosmetic dentistry and dental implants.

• Demand for certain dental procedures. Demand is growing for preventive dentistry and specialty

services such as periodontic (the treatment of gums), endodontic (root canals), orthodontic (braces),
and other dental procedures that enable patients to keep their natural teeth longer and improve their
appearance.

•

Increased dental office productivity. The number of dentists per 100,000 persons in the U.S. is
forecasted to decline over the next two decades. As a result, the number of patients per dental practice
is expected to grow. For this reason dentists are showing an increased willingness to invest in dental
equipment and office infrastructure that can strengthen the productivity of their practices.

• Demand for infection control products. Greater public awareness as well as regulations and guidelines
instituted by OSHA, the American Dental Association and state regulatory authorities have resulted in
increased use of infection control (asepsis) products such as protective clothing, gloves, facemasks, and
sterilization equipment to prevent the spread of communicable diseases such as AIDS, hepatitis and
herpes.

• Coverage by dental plans. An increasing number of dental services are being funded by private dental

insurance. In 2008, over 55% of the U.S. population had some form of dental coverage.

Strategy

Patterson’s objective is to remain a leading national distributor of supplies, equipment and related services

in the market while continuing to improve its profitability and enhance its value to customers. To achieve this
objective, Patterson has adopted a strategy of emphasizing its value-added, full-service capabilities, using
technology to enhance customer service, continuing to improve operating efficiencies, and growing through
internal expansion and acquisitions.

Emphasizing Value-Added, Full-Service Capabilities. Patterson Dental is positioned to meet virtually all of
the needs of dental practitioners by providing a full range of consumable supplies, equipment and software, and
value-added services. The Company believes that its customers value full service and responsive delivery of
quality supplies and equipment. Customers also increasingly expect suppliers to be knowledgeable about
products and services, and generally a superior sales representative can create a special relationship with the
practitioner by providing an informational link to the overall industry. The Company’s knowledgeable sales
representatives assist customers in the selection and purchase of supplies and equipment. In addition, the high
quality sales force allows Patterson to offer broader product lines. Since most dental practices lack a significant
degree of back office support, the convenience of our full-service capabilities enables dentists to spend more time
with patients and, thus, generate additional revenues.

Patterson meets its customer’s requirements by delivering frequent, small quantity orders rapidly and

reliably from its strategically located distribution centers. Equipment specialists, service technicians and
technology trainers also support the Company’s value-added strategy in the dental supply market. Equipment
specialists offer consultation on office design, equipment requirements and financing. Technology trainers from
the PTC provide guidance on integrating technology solutions including practice management and clinical
software, digital radiography, custom hardware and networking into the dental practice. The Company’s

5

experienced service technicians perform equipment installation, maintenance and repair services including
services on products not purchased through Patterson.

Using Technology to Enhance Customer Service. As part of its commitment to providing superior customer

service, the Company offers its customers easy order placement. The Company has offered electronic ordering
capability to its dental supply segment since 1987 when it first introduced Remote Order Entry (REMOSM). The
Company believes that its computerized order entry systems help to establish relationships with new customers
and increase loyalty among existing customers. The remote order entry systems permit customers to place orders
from their offices directly to Patterson 24 hours a day, 7 days a week. Over the years, the Company has continued
to introduce new order entry systems designed to meet the varying needs of its customers. Today the Company
offers four systems to the dental supply segment, eMagine®, REMOSM, PDXpress® and
www.pattersondental.com. Customers, as well as the Company’s sales force, use these systems. Over the years,
the number of orders transmitted electronically has grown steadily to approximately 69% of Patterson’s
consumable dental product volume or $840 million in fiscal year 2009.

In fiscal 2002, the Company introduced its newest order entry system, eMagine®. eMagine® has become the
standard platform for the sales representative and includes many new features and upgrades including up to three
years of order history for the customer’s reference, faster searches for products and reports, order tracking,
instant information on monthly product specials, descriptions and photographs of popular products and an
electronic custom catalog, including a printable version with scannable bar codes.

For those dental customers not using eMagine®, the Company offers two alternative order entry products.

REMOSM gives customers direct and immediate ordering access through a personal computer to a database
containing Patterson’s complete inventory. PDXpress® is a handheld order entry system that eliminates
handwritten order forms by permitting a user to scan a product bar code from an inventory tag system or from
Patterson’s bar-coded catalog. These systems, including eMagine®, are provided at no additional charge to
customers who maintain certain minimum purchase requirements.

The goal of the Company’s Internet strategy is to distribute information and service related products over
the Internet to enhance customers’ practices and to increase sales force productivity. The Company’s Internet
environment includes order entry, access to “Patterson Today” articles and manufacturers’ product information.
Additionally, Patterson utilizes a tool, InfoSource, to provide real time customer and Company information to the
Company’s sales force, managers and vendors via the Internet.

In addition to enhancing customer service, by offering electronic order entry systems to its customers, the
Company enables its sales representatives to spend more time with existing customers and to call on additional
customers.

The Company’s proprietary practice management and clinical software, EagleSoft®, is developed and
maintained by the PTC. The Company believes the PTC differentiates Patterson Dental from the competition by
positioning Patterson Dental as the only company providing a single-source solution for the high-growth area of
digital radiography. This technology, which the Company expects to be installed eventually in most dental
offices, has a current market penetration of approximately 30%. Among its many specialized capabilities, the
PTC provides system configuration, as well as the seamless integration of all digital operatory components with
clinical software, including our EagleSoft® line. This integration creates an electronic patient database that
combines the patient’s front office record with digital information from the clinical x-ray, intraoral camera,
CEREC and other digital equipment. Beginning in late fiscal 2008, the Company began offering EagleSoft
practice management software for free to customers. The PTC also will network the digital x-ray system
throughout the entire office and provide all required custom computer hardware for the system. In addition, the
PTC provides installation and customer training, as well as a call center for troubleshooting customer problems
and arranging for local service.

6

Software and digital radiography customers also have access to the support capabilities of the PTC. The
PTC provides support for our proprietary products as well as select branded product from our manufacturers. In
addition to troubleshooting problems through its customer call center, the PTC designs and configures local area
networks and assembles custom hardware. The PTC also develops and supports the Company’s order entry
systems.

Continuing to Improve Operating Efficiencies. Patterson continues to implement programs designed to
improve operating efficiencies and allow for continued sales growth over time. These programs include a wide
variety of initiatives from investing in management information systems to consolidating distribution centers.
Recent initiatives include upgrading the Company’s communications architecture, developing a new technical
service system, and implementation of the shared services concept.

The Company has improved operating efficiencies by converting its communications architecture to faster,

higher capacity data lines that combine voice and data transmissions. The Company has made substantial
progress in the development of a new field service management tool for its technical service operations. This new
tool will allow the Company to fundamentally change its technical service business processes, improving the
Company’s ability to coordinate the actions of its service technicians and enhancing customer service while
reducing the overall cost of operations.

An integral part of the Company’s shared services concept is the consolidation and leveraging of
distribution centers between the segments of the Company, which began in fiscal 2005. As of April 2009, the
dental segment shares seven distribution centers with one or both of the other operating units. In addition, the
Company has begun to establish shared sales branch office locations between multiple segments. As a result of
these and other efforts, the Company expects to continue to improve its operating leverage and efficiencies going
forward.

Growing Through Internal Expansion and Acquisitions. The Company intends to continue to grow by
opening additional sales offices, hiring established sales representatives, hiring and training college graduates as
territory sales representatives, and acquiring other distributors in order to enter new markets and expand its
customer base. The Company believes that it is well positioned to take advantage of expected continued
consolidation in the dental distribution market. Over the past 20 years the Company has made a number of
acquisitions, including the following:

Dental distribution acquisitions in the United States

•

In August 1987, Patterson acquired the D.L. Saslow Co., which at the time was the third largest
distributor of dental products in the United States. Between 1989 and 2005, Patterson acquired certain
assets of 25 smaller dental dealers throughout the United States. During fiscal 2002, the Company
acquired Thompson Dental Company of Columbia, SC, a leading value-added distributor of dental
supplies, equipment and services in the mid-Atlantic and southeastern U.S. Thompson ranked among
the 10 largest dental distributors in the country. In September 2005, the Company acquired Accu-Bite,
Inc., a Michigan-based dental distributor with approximately 60 field sales representatives. In April
2008, a full-service regional distributor serving customers in the northeastern U.S., Leventhal & Sons,
Inc., was acquired.

Dental distribution acquisitions in Canada

•

In October 1993, Patterson Dental completed the acquisition of Healthco International, Inc.’s Canadian
subsidiary, Healthco Canada, Inc. In August 1997, the Company acquired Canadian Dental Supply
Ltd., which expanded the Company’s market share in British Columbia, Alberta, Saskatchewan and
Ontario. In July 2002, the Company acquired Distribution Quebec Dentaire, Inc., augmenting the
Company’s market share in Quebec. As a combined operation known as Patterson Dental Canada Inc.,

7

this subsidiary, which the Company believes is one of the two largest full-service dental products
distributors in Canada, employs approximately 520 people, 150 of whom are sales representatives.

•

In September 2008, Patterson Dental acquired Denesca, a dental distributor serving the Toronto and
Montreal markets.

Printed office products acquisitions

•

In October 1996, Patterson acquired the Colwell Systems division of Deluxe Corporation. Colwell
Systems, now known as Patterson Office Supplies, produces and sells a variety of printed office
products used in medical, dental and veterinary offices, as well as other clinical based settings.

Software acquisitions

•

•

•

In July 1997, Patterson Dental acquired EagleSoft, Inc., a developer and marketer of Windows®-based
practice management and clinical software for dental offices. EagleSoft’s operation, now known as the
Patterson Technology Center, is located in Effingham, Illinois. In December 2001, the Company
purchased Modern Practice Technologies, a company that provides custom computing solutions to the
dental industry. This acquisition helped Patterson to position itself to provide all of the custom
hardware and networking required for interfacing the entire dental office.

In May 2004, Patterson Dental acquired CAESY Education Systems, Inc., the leading provider of
electronic patient education services to dental practices in North America. Headquartered in
Vancouver, Washington, CAESY provides dental practices with a range of communications media that
educates patients about professional dental care, procedures and treatment alternatives with the goal of
influencing patient decisions about dental services and increasing the productivity of the dental
professional. Educational materials are communicated through CD/DVD media, computer programs
and the dentist’s web site. These materials can be used within the dental waiting room, at chair side and
in the patient’s home.

In December 2008, Patterson Dental acquired Dolphin Imaging Systems, LLC and Dolphin Practice
Management, LLC, the leading providers of 3D imaging and practice management software for
specialized dental practitioners, including orthodontists, oral maxillofacial surgeons and dental
radiologists. Dolphin’s imaging software maximizes the benefit of cone beam and other digital
photography and radiography systems. The Company believes there are no major competitors for
Dolphin’s full range of product. Additionally, certain elements of Dolphin’s imaging software can be
integrated into Patterson Dental’s current line of EagleSoft software for general dental practitioners.

Consumable and Printed Products

Dental Supplies. Patterson offers a broad product line of consumable dental supplies such as x-ray film and

solutions; impression materials; restorative materials (composites and alloys); hand instruments; sterilization

8

products; anesthetics; infection control products such as protective clothing, gloves and facemasks; paper, cotton
and other disposable products; toothbrushes and a full line of dental accessories including instruments, burs, and
diamonds. In addition to representing a wide array of branded products from numerous manufacturers, Patterson
also markets its own private label line of dental supplies including anesthetics, instruments, preventive and
restorative products, and cotton and paper products. The private label line is used to complement the branded
products where the customer is seeking a lower-cost alternative on a product that has become commoditized in
the market. Compared to most name brand supplies, the private label line provides lower prices for the
Company’s customers and higher margins for the Company.

Printed Office Products. Patterson Dental provides a variety of printed office products, office filing
supplies, and practice management systems to office-based healthcare providers including dental, veterinary and
medical offices. Products include custom printed products, insurance and billing forms, stationery, envelopes and
business cards, labels, file folders, appointment books and other stock office supply products. Products are sold
through two channels:

• The Company’s dental and veterinary supply sales force

• Direct mail catalogs distributed to over 100,000 customers several times a year

A staff of telemarketing personnel located in Champaign, Illinois supports both channels. Orders are
received by telephone, through the mail or electronically from the dental and veterinary distribution order
processing system.

Equipment and Software

Dental Equipment. Patterson Dental is the largest supplier of dental equipment in the U.S. and Canada. It

offers a wide range of dental equipment products including x-ray machines, high-and low-speed handpieces,
dental chairs, dental handpiece control units, diagnostic equipment, sterilizers, dental lights and compressors. The
Company also distributes newer technology equipment that provides customers with the tools to improve
productivity and patient satisfaction. Examples of such innovative and high-productivity products include the
CEREC® family of products, a chair-side restoration system; digital x-rays; and intraoral cameras.

Software. Patterson develops and markets its own proprietary line of practice management and clinical
software for dental professionals. Products include software for scheduling, billing, charting and capture/storage/
retrieval of digital images. The Company also sells software products developed by third parties including
Sidexis by Sirona and Dimax2 by Planmeca. These value-added products are designed to help achieve office
productivity improvements, which translate into higher profitability for the customer.

Hardware. Patterson Dental offers custom hardware and networking solutions required for integrating the
entire dental office. This product offering is available to all of the Company’s dental customers. This initiative
marked another step in Patterson’s overall strategy of providing customers with the convenience and cost-
effectiveness of a virtually complete range of products and value-added services and is one of the newest
components of Patterson’s single-source solution for dental offices.

Patient Education Services. The CAESY Patient Education Systems line of products offers patient
education products and services. These communications tools are designed to influence patient decisions about
services in an efficient, cost-effective manner.

Other

Software Services. The Company offers a variety of services to complement its software products such as

service agreements, software training, electronic claims processing and billing statement processing. These

9

services provide value to customers by allowing them to keep software products current, or receive payments
more rapidly while obtaining greater productivity.

Equipment Installation, Repair and Maintenance. To keep their practices running efficiently, dentists
require reliable performance from their equipment. All major equipment sold by Patterson includes installation
and Patterson’s 90-day labor warranty at no additional charge. Patterson also provides complete repair and
maintenance services for all dental equipment, whether or not purchased from Patterson, including 24-hour
handpiece repair service. In addition to service technicians who provide installation and repair services on basic
dental equipment, the Company has also invested in personnel who specialize in installing and troubleshooting
issues with technology solutions such as practice management software, digital imaging products, hardware and
networking. The goal of this group, which is comprised of both local service technicians and the Patterson
Technology Center, is to help customers integrate newer technology into their dental practices. The Patterson
Technology Center helps the customer minimize costly downtime by offering a single point of contact for post-
sale technology related issues.

Dental Office Design. Patterson provides dental office layout and design services through the use of a
Computer-Aided Design (CAD) program. Equipment specialists can create original or revised dental office
designs in a fraction of the time required to produce conventional drawings. Customers purchasing major
equipment items receive dental office design services at no additional charge.

Equipment Financing. Patterson Dental provides a variety of options to fulfill its customers’ financing
needs. For qualified purchasers of equipment, the Company will arrange financing for the customer through
Patterson or a third party. For non-equipment related needs, such as for working capital or real estate, customers
are referred to a third party organization. This alternative allows the Company to offer its customers convenience
while still meeting their diverse financing needs. In fiscal 2009, the Company originated nearly $300 million of
equipment finance contracts. The Company, or its vendor partner, financed more than 35% of the equipment
purchased by customers during fiscal 2009.

Since November 1998, Patterson has maintained one or more finance referral agreements with an outside

finance company to provide a more extensive selection of finance opportunities to its customers. This might
include financing for practice transactions, working capital, leasing, real estate and long-term capital. Currently
this service is provided by Matsco, a division of Wells Fargo Bank N.A. There are no recourse provisions under
this agreement. Patterson receives referral fees under this agreement and Matsco extends credit and services the
accounts.

Patterson generally does not hold the finance contracts initiated on equipment transactions. These contracts

are sold to either a commercial paper conduit managed by JPMorgan Chase Bank, N.A., or to a group of banks
led by U.S. Bank National Association.

Patterson created a special purpose entity (“SPE”), PDC Funding Company, LLC, a wholly-owned and fully

consolidated subsidiary, and entered into a Receivables Purchase Agreement in order to participate in the
commercial paper conduit. The Company transfers installment sale contracts to the SPE. In turn, the SPE sells
the contracts to the commercial paper conduit. The limit under this agreement is $367 million of contract
purchases. There is no recourse to the Company for contracts purchased by the commercial paper conduit, but
there is a holdback by the conduit equal to 10% of the principal of these contracts.

A second SPE, PDC Funding Company II, LLC, can sell contracts through a Contract Purchase Agreement
to a group of banks led by U.S. Bank. The agreement operates similarly to the Receivables Purchase Agreement
described above, except that the holdback is equal to 6% of the principal and the capacity is $110 million.

10

Patterson services the customer contracts under both of the preceding arrangements for which it receives a

fee that approximates its cost for providing the service.

Sales and Marketing

During fiscal 2009, Patterson Dental sold products or services to over 120,000 customers in the U.S. and

Canada who made one or more purchases during the year. Patterson Dental’s customers include dentists,
laboratories, institutions and other healthcare professionals. No single customer accounted for more than 1% of
sales during fiscal 2009, and Patterson is not dependent on any single customer or geographic group of
customers. The Company’s sales and marketing efforts are designed to establish and improve customer
relationships through personal interaction with its sales representatives and frequent direct marketing contact,
which underscores the Company’s value-added approach.

Patterson Dental has over 90 local offices throughout the U.S. and Canada so that it can provide a presence

in the market and decision making near the customer. These offices, or branches, are staffed with a complete
complement of Patterson Dental capabilities, including sales, customer service and technical service personnel,
as well as a local manager who has broad decision making authority with regard to customer related transactions
and issues.

A primary component of Patterson’s value-added approach is its sales force. Due to the fragmented nature
of the dental supply market, Patterson believes that a large sales force is necessary to reach potential customers
and to provide full service. Sales representatives provide an informational link to the overall industry; assist
practitioners in selecting and purchasing products and help customers efficiently manage their supply inventories.
Each sales representative works within an assigned sales territory under the supervision of a location (branch)
manager. Sales representatives are all Patterson employees and are generally compensated on a commission
basis, with some less experienced representatives receiving a base salary and commission.

To assist its sales representatives, Patterson Dental publishes a variety of catalogs and fliers containing
product and service information. Dental customers receive a full-line product catalog containing over 30,000
inventoried items. The catalog includes pictures of products, detailed descriptions and specifications of products
and is utilized by practitioners as a reference source. Selected consumable supplies, new products, specially
priced items and high-demand items such as infection control products are promoted through merchandise fliers
printed and distributed bi-monthly to the dental supply market. In addition, dental equipment sold by Patterson is
featured in Patterson’s tri-yearly publication, Patterson Today, which also includes articles on dental office
design, trends in dental practice, products and services offered by Patterson and information on equipment
maintenance.

To enhance the total value it brings to its customers, Patterson Dental offers a value-added benefit program

for its preferred customers. A new program, Patterson AdvantageSM, replaced the former Patterson PlusSM
program effective January 2009. The Patterson Advantage program enables members to earn “Advantage
Dollars” which can be applied toward future purchases of equipment and technology products. Patterson
Advantage also entitles its best customers to priority technical services, automated supply management summary
reports, and a variety of exclusive discount offers.

Distribution

Patterson Dental believes that responsive delivery of quality supplies and equipment is a key element to
providing complete customer satisfaction. Patterson ships dental consumable supplies from eight strategically
located distribution centers in the U.S. and two in Canada. Orders for consumable dental supplies can be placed
by telephone or electronically 24 hours a day, seven days a week. Printed office products are shipped from the
Company’s manufacturing and distribution facility in Illinois.

All orders are routed through Patterson’s centralized computer ordering, shipping and inventory

management systems, which are linked to each of the Company’s strategically located distribution centers. If an

11

item is not available in the distribution center nearest to the customer, the computer system automatically directs
shipment of the item from another center. Rapid and accurate order fulfillment is another principal component of
the Company’s value-added approach. Patterson Dental estimates that 98% of its consumable goods orders are
shipped to the customer on time, which is generally within 24 hours.

In order to ensure the availability of Patterson Dental’s broad product lines for prompt delivery to

customers, Patterson must maintain sufficient inventories at its distribution centers. Purchasing of consumables
and standard equipment is centralized and the purchasing department uses a real-time perpetual inventory system
to manage inventory levels. The Company’s inventory consists mostly of consumable supply items. By utilizing
its computerized inventory management and ordering systems, the Company is able to accurately predict
inventory turns in order to minimize inventory levels for each item.

Patterson Dental’s more than 90 dental sales offices are generally configured with display areas where the
latest dental equipment can be demonstrated. Dental equipment is generally custom ordered and is staged at the
Company’s sales offices before delivery to dental offices for installation.

Sources of Supply

Effective purchasing is a key strategy the Company has adopted in order to achieve its objective of

continuing to improve profitability. The Company has a program to effectuate electronic data interchange (EDI)
with its major vendor partners. In fiscal 2009, the Company processed approximately 70% of its invoices from
dental vendors using EDI capabilities. In addition, approximately 60% of Patterson’s dental purchase order
volume was conducted employing EDI. Utilizing EDI allows the Company to improve efficiencies and reduce
administrative costs.

Patterson Dental obtains products from more than 1,000 vendors in the dental segment. Patterson has
exclusive distribution agreements with several quality dental equipment manufacturers including Sirona Dental
Systems, Inc. for CEREC® dental restorative systems and digital x-rays. The Company is the only national dealer
for A-dec equipment, including chairs, units and cabinetry. A-dec is the largest manufacturer of dental equipment
in the U.S.

While the Company makes purchases from many suppliers and there is generally more than one source of

supply for most of the categories of products sold by the Company, the concentration of business with key
suppliers is considerable. The Company’s top 10 supply vendors accounted for approximately 42% and 41% of
the cost of dental products sold in fiscal years 2009 and 2008, respectively. Of these 10, the top two vendors
accounted for 10% and 9%, and 9% and 9% of fiscal 2009 and fiscal 2008 cost of sales, respectively.

Competition

The highly competitive U.S. dental products distribution industry consists principally of national, regional
and local full-service and mail-order distributors. The dental supply market is extremely fragmented. In addition
to Patterson and one other national, full-service firm, Sullivan-Schein Dental, a unit of Henry Schein, Inc., there
are at least 15 full-service distributors that operate on a regional level, and hundreds of small local distributors.
Also, some manufacturers sell directly to end-users.

The Company approaches its markets by emphasizing and delivering a value-added model to the
practitioner. To differentiate itself from its competition it deploys a strategy of premium customer service, a
highly qualified and motivated sales force, experienced service technicians, an extensive breadth and mix of
products and services, accurate and timely delivery of product, strategic location of sales offices and distribution
centers, and competitive pricing.

12

The Company also experiences competition in Canada in the dental supply market. The principal competitor

is a national, full-service dental distributor, Henry Schein Ash Arcona, a unit of Henry Schein, Inc. The
Company believes it competes in Canada on essentially the same basis as in the United States.

Veterinary Supply

Overview

Webster Veterinary, or “Webster,” is the leading distributor of veterinary supplies to companion-animal

(dogs, cats and other common household pets) veterinary clinics in the eastern United States. Management
believes Webster is the second largest distributor of companion-animal veterinary supplies nationally. In
addition, through its fiscal 2005 acquisition of Milburn Distributions, Inc., Webster is the leading national equine
distributor in the United States. Webster provides products used for the diagnosis, treatment and/or prevention of
diseases in companion pets and equine animals. Founded in 1946 and headquartered in Sterling, Massachusetts,
Webster has developed a strong brand identity as a value-added, full-service distributor of a virtually complete
range of consumable supplies, equipment, diagnostic supplies, biologicals (vaccines) and pharmaceuticals.
Webster’s product offering, totaling more than 11,000 items, is sold by approximately 235 field sales
representatives. In addition to its core business of distributing veterinary products, Webster has a significant
agency commission business with a few large pharmaceutical manufacturers. Under the agency relationships,
Webster typically earns a commission for soliciting orders through its sales force. In the agency relationship,
Webster processes the order to the manufacturer but handles none of the product nor does Webster bill and
collect from the customer. The agency commissions that Webster earns range from 3% to 10%, a portion of
which is shared with the direct sales personnel. Webster’s agency commissions accounted for less than 1% of its
net sales in fiscal 2009. Net sales by Webster in fiscal 2009 were $550.6 million. Operating income totaled $26.1
million.

The Company estimates the market for pharmaceuticals and supplies sold to companion animal and equine

veterinarians through distribution is approximately $2.9 billion on an annual basis. Based upon the estimated
$2.9 billion market, the Company believes its share of this market is approximately 19%. Similar to the dental
supply market, the veterinary supply market is fragmented and geographically diverse. There are approximately
79,000 veterinarians practicing at 27,000 animal health clinics. The vast majority, approximately 67% of
veterinarians, work in private animal health clinics specializing in small animals, predominately companion pets.
The average private veterinary practice generates approximately $770,000 of annual revenue. These practices
purchase between $80,000 and $120,000 of supplies each year, and similar to the dental practitioner, do not
maintain a large supply of inventory on hand. The typical veterinary practice purchases approximately 80% of its
supplies from its top two suppliers. The average purchase of consumables by the veterinary practice is noticeably
higher than that of the dental practitioner due predominately to pharmaceutical products which are administered
and dispensed by veterinarians.

Over the past 15 years, the demand for veterinary services has grown significantly faster than growth in the

overall economy. The companion pet segment is the fastest growing area of the overall U.S. veterinary supply
market. The Company believes this growth is sustainable due to the following favorable factors:

• Number of households with companion animals. The number of households with companion animals is
steadily expanding which increases the demand for veterinary services. Today, 62% of U.S. households
own a companion pet compared with 56% in 1988. Overall, 45% of all households in the U.S. own
more than one pet.

• Veterinary expenditures per household. The amount pet owners are willing to spend caring for their

pets is increasing substantially. The American Pet Products Manufacturers Association estimates that
pet owners will spend $45.4 billion in 2009 to care for the American pet population. This is a 167%
increase over the $17 billion spent in 1994.

13

• Veterinary products and techniques. Many new therapeutic and preventive products are being

developed for the companion animal market. Technological developments have resulted in new
innovative veterinary products and advances in veterinary services.

Strategy

Webster’s objective is to build a leading national position in the companion animal veterinary market
through internal expansion and acquisitions, while continuing to improve its profitability and enhance its value to
customers. Its key strategies and priorities for accomplishing this are to open new geographic markets, make
acquisitions that expand market share, emphasize value-added capabilities, consistently improve operating
efficiencies and broaden the product offering.

Growing Through Internal Expansion and Acquisitions. In April 2004, Webster acquired the assets of
ProVet, which was the companion animal veterinary supply division of Lextron, Inc. ProVet was a distributor
with locations in Indianapolis, Kansas City, Houston, Denver and Seattle. Management believes this acquisition
made Webster the second largest distributor of companion-animal veterinary supplies in the U.S. This acquisition
added 44 sales representative territories expanding Webster’s geographic coverage to include the states of
Indiana, Illinois, Missouri, Kansas, Oklahoma, Colorado, Nevada, Idaho and Oregon. In addition, the acquisition
increased market coverage in Washington state and Texas where Webster already had a presence.

In October 2004, Webster acquired Milburn Distributions, Inc., the largest distributor specializing in the
U.S. equine veterinary supply market. Milburn’s annualized sales exceed $50 million. The company operates
facilities in Arizona, Kentucky, Texas and Florida. Most companion-animal and large animal veterinary supply
distributors have not successfully served the nation’s equine veterinarians due to the highly specialized nature of
this niche market. Milburn has capitalized on this opportunity by focusing exclusively on the unique needs of
equine veterinarians.

In fiscal 2006, Webster grew through both an acquisition and greenfield expansion. In December 2005, it
acquired Intra Corp., one of the nation’s leading developers of veterinary practice management software that is
marketed under the IntraVet brand name. IntraVet has more than 1,600 software installations nationwide and
furthers Webster’s strategy of establishing a value-added business platform similar to that of Patterson Dental.

Also in fiscal 2006, Webster developed business through a program of internal start-ups, including
operations in Ohio, Michigan and California. The expansion into California, which had been Webster’s largest
unserved market, was particularly successful and has made a solid contribution to Webster’s sales results.

During fiscal 2008, Webster acquired New England X-Ray, Inc. in the first quarter and Associated Medical

Supply, Inc. in the fourth quarter. New England X-Ray expanded product and service offerings and Associated
Medical Supply, Inc. strengthened Webster’s competitive position in the southwestern U.S.

In October 2008, Webster acquired Columbus Serum Company, a full service distributor of companion-pet

veterinary supplies, equipment and pharmaceuticals. Columbus Serum, with sales of over $160 million, serves
veterinarians in the Midwest and mid-Atlantic regions and further strengthened Webster’s position in these
markets. Also in October 2008, Webster acquired Odyssey Veterinary Software, LLC, a developer and marketer
of Diagnostic Imaging Atlas (“DIA”) software. DIA encompasses over 2,000 3D clinical animations and images,
which enable the veterinarian to more fully explain and illustrate the pet’s diagnosis and recommend treatment to
their clients.

Emphasizing Value-Added, Full-Service Capabilities. Webster believes that veterinary customers value full
service and responsive delivery of product, in addition to competitive prices. Customers also increasingly expect
suppliers to be knowledgeable about products and services, and generally a superior sales representative can
create a special relationship with the practitioner by providing an informational link to the overall industry.

14

Webster’s knowledgeable sales representatives assist customers in the selection and purchasing of supplies. Most
veterinarians are independent, or small unit based, practitioners who are unable to store and manage large
volumes of supplies in their offices. Webster meets its customer’s requirements by delivering frequent, small
quantity orders rapidly and reliably from its strategically located distribution centers.

Continuing to Improve Operating Efficiencies. Webster continuously pursues opportunities to lower costs

and improve efficiencies. As of April 2009, Webster shares four distribution facilities with one or both of the
other operating units. In addition, a customer system that can be used by multiple business segments but
maintains the same look and feel of the eMagine® system has been fully deployed within the unit. The system
provides customer support staff with integrated customer information on one screen.

Broaden the Product Line. Webster continuously seeks to broaden its portfolio of product offerings to
maximize the opportunities within its existing customer base. In fiscal 2005, Webster successfully launched its
private label initiative to supply veterinary customers with quality consumable goods (white goods, exam gloves,
sutures, surgical blades and microscope slides) at value prices. Private label offerings have since been expanded
and are expected to continue to grow. Management believes that product innovation allows Webster to maintain
its competitive position and helps fuel internal growth. Management also believes that its emphasis on new
product offerings enables its sales force to remain effective in creating demand among veterinarians.

Broadening the product line also includes bringing new, innovative services to the customer to allow them
to generate greater revenues and profitability from their practice. As Webster continues to expand and build its
equipment business, it has added clinic and hospital design capabilities and technical service personnel to install
and repair equipment that is sold by Webster as well as by others. With the acquisitions of the IntraVet practice
management and DIA software products, new services and revenue opportunities have become possible.

Consumable and Printed Products

Webster offers its customers a broad selection of veterinary supply products including consumable supplies,
pharmaceuticals, diagnostics, and biologicals. Consumable supplies distributed by Webster include lab supplies,
various types and sizes of paper goods, needles and syringes, gauze and wound dressings, sutures, latex gloves,
orthopedic and casting products. Webster’s pharmaceutical products include anesthetics, antibiotics, injectables,
ointments and nutraceuticals. The diagnostics product category includes on-site testing products for heartworm,
FIV, FELV and parvovirus. Biological products are comprised of vaccines and injectables. Many of the office
supply products sold to the dental supply market are also offered to the veterinary supply market.

Equipment and Software

Webster sells equipment for hospital, laboratory and general surgical use within the veterinary practice.
Webster offers innovative, quality equipment that differentiates Webster from the competition. About 50% of
veterinary equipment orders are drop shipped directly to the customer, of which 15% are custom ordered from

15

the manufacturer. The other half of veterinary equipment is distributed in a manner similar to consumable
supplies. Webster has expanded its software offerings through acquisitions to include IntraVet practice
management software and DIA software.

Other

Other products and services include commissions on agency sales, equipment repair revenues, software

maintenance contract revenue and freight recovery on shipments to customers.

Sales and Marketing

A primary component of Webster’s value-added approach is its sales force. Due to the fragmented nature of

the veterinary supply market, Webster believes that a large sales force is necessary to reach potential customers
and to provide full service. Sales representatives provide an informational link to the overall industry, assist
practitioners in selecting and purchasing products, and help customers efficiently manage their supply
inventories. Each representative works within an assigned sales territory under the supervision of a location
(branch) manager. Sales representatives are employees and are generally compensated on a commission basis,
with some, less experienced, representatives receiving a base salary and commission.

To assist its sales representatives, Webster publishes a catalog, which contains approximately 11,000 SKUs.

This catalog includes detailed descriptions and specifications of products and is utilized by practitioners as a
reference source. Selected consumable supplies, new products, specially priced items and high-demand items are
promoted through merchandise fliers printed and distributed monthly.

Webster’s website was built upon the proven technology of the Patterson Dental website and the site allows

customers the ability to order items twenty-four hours a day, seven days a week. The website also incorporates
value-added functions that permit customers to check their invoice, payment and credit history, build a “shopping
list” of frequently purchased items and track their order status.

Distribution

As of April 25, 2009, veterinary products were stocked and shipped out of 13 distribution centers. The

distribution of veterinary products is complemented by telesales representatives who are responsible for
processing approximately 70% of customer orders in this segment. In order to meet the rapid delivery
requirements of customers, most consumable products are delivered within 24 hours. Webster estimates that
approximately 98% of its consumable orders are delivered to the customer on time.

Sources of Supply

Webster obtains products from nearly 550 vendors. While Webster makes purchases from many suppliers

and there is generally more than one source of supply for most of the categories of products, the concentration of
business with key suppliers is considerable. In fiscal 2009 and 2008, Webster’s top 10 veterinary supply
manufacturers comprised 65% and 62%, respectively, and the single largest supplier comprised 15% and 17%,
respectively, of the total cost of veterinary supply sales.

Competition

Within the “companion pet” market segment, competitors range from small local distributors to large

national and regional full-service companies, and to a lesser extent, mail order distributors or buying groups.
Webster also competes directly with pharmaceutical companies who sell certain products directly to the
customer.

The Company approaches its markets by emphasizing and delivering a value-added model to the
practitioner. To differentiate itself from its competition it deploys a strategy of premium customer service, a

16

highly qualified and motivated sales force, an extensive breadth and mix of products and services, accurate and
timely delivery of product, strategic location of sales offices and competitive pricing.

Rehabilitation Supply

Overview

Patterson Medical is headquartered in Bolingbrook, Illinois and is the world’s leading distributor of
rehabilitation medical supplies and non-wheelchair assistive products. Patterson Medical believes it offers the
most comprehensive range of distributed and self-manufactured rehabilitation products to health care
professionals globally. Its mission is to provide health care professionals and their patients with access to
products that improve peoples’ lives by helping them to attain their highest achievable level of independence,
safety and comfort. Patterson Medical operates as Sammons Preston and Medco Sports Medicine in North
America and Homecraft in international markets.

Patterson Medical serves as the gateway through which over 30,000 rehabilitation products originating from

more than 2,000 suppliers and manufacturers are sold to a diverse customer base with an emphasis on physical
therapists (“PTs”) and occupational therapists (“OTs”). It offers its customers a “one-stop shop” through what it
believes to be the most comprehensive catalog in the industry, the largest direct sales force and the category’s
most efficient customer service and distribution operations. Major channels of distribution are acute care
hospitals, long-term care facilities, rehabilitation clinics, dealers and schools. In addition, Patterson believes
Patterson Medical’s reputation, global market presence and highly transferable business model will facilitate
entry into new markets.

Patterson Medical offers a wide range of differentiated, non-invasive products and expertise to users and

their health care providers, while focusing on niches, worldwide, where its capabilities, reputation and customer
partnerships can result in a competitive advantage. Its goal is to become its customers’ first choice for
rehabilitation medical supplies and assistive products in each of its chosen markets.

Patterson Medical is highly diversified with no single product, customer or purchasing group representing a

significant percentage of total revenue. In addition, given the relatively small average and median order size
(approximately $225 and $70, respectively), Patterson Medical’s products often do not represent a major expense
category for its customers.

In March 2002, Patterson Medical completed the acquisition of the Smith & Nephew Rehabilitation
(“SNR”) division of Smith & Nephew PLC, and in doing so, acquired the Rolyan, Homecraft and Kinetec brand
names. The SNR acquisition added 3,500 additional products, as well as a broad array of other brand names and
proprietary products. The acquisition of SNR combined the two leading distributors of rehabilitation medical
supplies to create what Patterson believes is the only “one-stop shop” in the industry. Patterson Medical
manufactures or has exclusively manufactured for it products representing approximately 25% of its total
revenue and purchases products representing the remaining 75%. Approximately 85% of its revenue is in North
America.

Patterson Medical believes the rehabilitation medical supplies and assistive products industry is

approximately $4.6 billion in the U.S. and $6.2 billion worldwide and is expected to grow faster than the overall
economy over the next several years. Industry growth is driven by strong growth in the physical and occupational
therapy markets and favorable demographic trends associated with the aging of the baby-boom generation.
Patterson Medical does not compete in motorized-wheelchairs or scooters, a market estimated to be a combined
$2.2 billion worldwide. Therefore, Patterson Medical’s addressable market (defined as the collective market for
products sold by Patterson Medical) is approximately $4.0 billion worldwide. Patterson Medical believes that it
has an industry leading market share of approximately 6% in a highly fragmented rehabilitation and assistive
products market.

17

Patterson Medical believes that the demand for rehabilitation products will continue to be influenced by the

following factors:

• Favorable Demographics. Favorable demographic trends such as extended life expectancy, active

lifestyles and a general willingness to spend discretionary income on health care and well being, are
expected to contribute to increased demand for products distributed by Patterson Medical. Specifically,
the aging baby-boomer population, together with their increased disposable income and desire for
independence, will fuel product purchases to assist with the frailties associated with old age and
provide sustained sales growth.

The U.S. Census Bureau has projected the 85 year and older populations in the U.S. to more than triple
from four million in 2000 to 14 million by 2040. The 65 to 84 year old population is expected to more
than double during the same time period. Current trends indicate that these age groups represent the
majority of home and community-based health care patients.

The aging of the population is a revenue growth driver. Approximately 10% of people over the age of
65 and approximately 50% of people over the age of 85 need assistance with everyday activities.
Patterson Medical believes it is well positioned to benefit from this trend by providing aids to daily
living, namely dressing devices; toileting, dining, bathing aids; and grooming devices, all of which
promote greater patient independence, improved patient responsibility and improved responsiveness to
treatment.

Increasing Number of PTs and OTs, Patterson Medical’s Primary User Groups. According to the U.S.
Department of Labor Occupational Outlook Handbook, there were approximately 132,000 PTs and
78,000 OTs in the U.S. in 2000. Approximately two-thirds of PTs were employed in either hospitals or
offices of physical therapists. The remaining one-third of PTs was employed in home health agencies,
outpatient rehabilitation clinics, physician offices and nursing homes. The majority of OTs work in
hospitals, including many in rehabilitation and psychiatric hospitals. The remaining OTs work in
outpatient occupational therapy offices and clinics, schools, home health agencies, nursing homes,
community mental health centers, adult day care programs, job training services and residential care
facilities. The demand for PTs and OTs is expected to remain strong largely driven by the (i) increase
in the number of individuals with disabilities or limited function requiring therapy services; (ii) rapidly
growing elderly population which is particularly vulnerable to chronic and debilitating conditions that
require therapeutic services; (iii) baby-boom generation which is entering the prime age for heart
attacks and strokes, increasing the demand for cardiac and physical rehabilitation; (iv) advances in
medical technology which permit treatment of more disabling conditions; and (v) widespread interest
in health promotion.

Increasing Frequency of Reconstructive and Implant Surgery. Another important driver of the growth
in the PT market is the growing need for rehabilitation products resulting from the increasing
frequency of reconstructive implant procedures, including hip and knee replacements. The worldwide
reconstructive implant market is currently in excess of $5.0 billion and expected to grow between 7%
and 8% annually. This growth trajectory is largely driven by favorable demographics, as patient
populations are expanding at both ends of the age spectrum. Among seniors, more active lifestyles and
longer life expectancies are responsible for the increasing frequency of reconstructive implants.
Younger patients are opting for reconstructive implants over less invasive alternatives due to improved
and longer lasting implant technology. Patterson Medical believes it is well positioned to benefit from
the growth in reconstructive implants, by providing orthopedic products, namely Continuous Passive
Motion machines and splinting, which are critical to post-operatory rehabilitation.

International Operations

Patterson Medical’s international operations are based in the United Kingdom (“U.K.”) and are made up of

two divisions: Homecraft in the U.K. and Kinetec in France. The international operations broadly reflect the

18

same business model as used in the North American market. In the U.K., Homecraft operations include sales and
marketing, customer service, distribution, purchasing and administration. In France, Kinetec is a self-contained
manufacturing unit with limited sales and marketing, distribution, administration and purchasing.

Homecraft is a leading supplier of aids to daily living (“ADL”) and rehabilitation products in the U.K., and a

significant player in the international markets. Having developed and designed many proprietary products,
Homecraft is the prime source for numerous established and market leading ADL brands, including products sold
under the Sammons Preston Rolyan brand. The Homecraft catalog offers a broad line of ADL, therapy,
rehabilitation and pediatric products containing over 10,000 items. Their catalog is circulated to PTs, OTs, loan
equipment stores and private clinics, trade outlets and the general public.

Homecraft’s central sales and marketing strategy is to provide a “one-stop shop” proposition to hospitals,
local government and trade customers throughout the U.K. Customers are reached through a combination of mail
order, a 15 person sales force, telemarketing and in-market promotional and exhibition activity.

In April 2009, Homecraft acquired Mobilis Healthcare, further increasing Homecraft’s presence in the U.K.

While Homecraft has historically been focused on occupational therapy, Mobilis has a strong position in the
physical therapy market.

Kinetec consists of two operations, the manufacturing and distribution of Continuous Passive Motions
machines (“CPMs”) for sale on a worldwide basis and the sale and distribution of Sammons Preston Rolyan and
Homecraft products in France. Products are marketed to customers through product brochures, mailings, tele-
marketing and a six person sales force that covers the French rehabilitation market.

Strategy

Patterson Medical’s objective is to be the customers’ first choice for rehabilitation medical supplies and
non-wheelchair assistive products in each of its chosen markets. It intends to grow through internal expansion
and acquisitions in both rehabilitation and related products. In the second half of fiscal 2006, a new management
team was installed and has been responsible for accelerating the unit’s adoption of Patterson’s value-added
strategy.

Emphasizing Value-Added, Full-Service Capabilities. Patterson Medical currently offers their customer a
“one-stop shop” for products through their industry-leading catalog with over 20,000 items, focused primarily on
physical and occupational therapy products. Patterson Medical adds new products each year to its ever-expanding
catalog and is committed to doing so long-term. Consistent with Patterson Medical’s current product offering,
some of these new products are branded, exclusive or self-manufactured.

Patterson Medical recognizes that different customer groups have very different economic, product and
distribution channel requirements and treatment goals. Patterson Medical proactively attempts to anticipate and
flexibly respond to the diverse needs of its customers, while focusing on niches, worldwide, where its
capabilities, reputation and customer partnerships can result in a competitive advantage. As such, Patterson
Medical foresees an ongoing evolution of its product offerings to meet the ever-increasing demands of its diverse
customer segments.

Improving Operating Efficiencies. Patterson Medical’s proprietary products, which consist of self-
manufactured products, products manufactured for Patterson Medical and products sold through exclusive
distribution arrangements represent approximately 25% of total revenues. Over the past three years, Patterson
Medical made investments in new sales and marketing programs as a part of its accelerated adoption of
Patterson’s value-added strategy, including the expansion of its sales force and the establishment of a branch
office structure. The Company believes these investments will result in additional sales and operating efficiencies
into the future.

19

As of April 2009, the unit is distributing products from four shared distribution facilities that distribute
products for two or all three Patterson operating units. In addition, the first shared branch office location was
created late in fiscal 2007 in Northern California. This branch location includes both dental and rehabilitation
segment personnel, while allowing the two units to share in certain common expenses. There are now four shared
branch facilities.

Growing Through Internal Expansion and Acquisitions. Patterson Medical believes it is well positioned to

expand in its core markets. Patterson Medical’s market presence, clinical understanding and close customer
relationships allow Patterson Medical to anticipate and flexibly respond to the diverse needs of its customers.
Patterson Medical believes its market knowledge, strong vendor relationships and manufacturing capabilities will
continue to drive the delivery of value-added solutions through the continual enrichment of its product mix.
Additionally, Patterson Medical believes its broad portfolio of national accounts and commitment to expand its
sales force will enhance Patterson Medical’s growth and penetration within its current and new customer base.

Patterson Medical acquired Homecraft and Kinetec as part of the SNR transaction. Patterson Medical is
leveraging this platform to accelerate international expansion, in terms of both product lines and geographic
regions. Since the SNR transaction, Patterson Medical has added over 550 pages of new products to the
Homecraft catalog. Homecraft and Kinetec brought with them a proven capability to source products at very
favorable costs and at high levels of quality from China, which has resulted in meaningful cost savings. Patterson
Medical’s management team believes its business model is transferable to other countries, and is using
Homecraft to cultivate new relationships through an enhanced product array, sales effort, distribution capabilities
and catalog expertise.

In May 2004, Patterson Medical acquired the assets of Medco Supply Company, Inc., or “Medco,” from

NCH Corporation. With sales of approximately $57 million, Medco is one of the nation’s leading sports
medicine distributors and is based in Buffalo, New York. In addition to its sports medicine business, it sells first
aid, safety and medical consumable products to commercial and institutional customers, as well as consumable
supplies and equipment to podiatrists. The complete product offering includes approximately 10,000 SKUs that
are sold through direct mail catalogs and 13 territory sales people. Medco markets to athletic trainers, schools
and school nurses, daycare providers and healthcare professionals including podiatrists, chiropractors and
physical therapists.

Over the past three years, the unit has opened 12 branch offices through acquisitions and internal start-ups in
desirable locations throughout the U.S. In November 2007, Patterson Medical acquired PTOS software, a leading
line of practice management software for physical therapists.

In April 2009, Patterson Medical acquired Mobilis Healthcare, a U.K.-based business with sales of $28
million. Mobilis serves 12,000 customers in the U.K. and France and owns several leading brands that are sold
into its primary markets.

Patterson Medical operates in the highly fragmented rehabilitation medical supplies and non-wheelchair
assistive products industry. Patterson Medical’s competition is generally either locally or regionally focused.
Patterson Medical intends to pursue expansion opportunities when prudent in order to add products, customers
and capabilities, which will further differentiate Patterson Medical from its competition.

Consumables

Patterson Medical offers a large selection of supply products that can be categorized as follows:

• Aids to Daily Living—dressing devices, toileting, dining, bathing aids and grooming devices

• Orthopedic Soft Goods / Splints—braces, splints and orthotics for protecting, supporting and

positioning

• Clinical—products that assist in the examination and treatment of patients, such as exercise bands,

putty, weights balls and mats

• Mobility—walkers, canes and wheelchair accessories such as gloves, trays and carrying bags

•

Pediatric Seating and Positioning—rolls, wedges, specialty seating and standers and mobility
assistance products for special needs children. This category also includes sensory motor stimulation
products such as toys, crafts and devices to assist with balance

• Modalities—products for heating and cooling therapies, electrical stimulation, laser, ultrasound,

paraffin, iontophoresis and therapeutic creams and lotions

Equipment and Software

Rehabilitation equipment consists of exercise, examination, treatment and therapy equipment and furniture.
These products include parallel bars, treatment tables, mat platforms, treadmills, stationary bicycles and CPMs.
The November 2007 acquisition of PTOS software added a line of practice management software to Patterson
Medical’s wide array of product offerings. In addition, certain acquisitions over the past two years have given the
unit access to premium equipment lines that were previously unavailable to Patterson Medical.

Sales and Marketing

Its customers generally know Patterson Medical as Sammons Preston in the U.S. and Canada, and
Homecraft in the remainder of the world. The Sammons Preston and Homecraft business models, which
Patterson Medical employs in the U.S., Canada and the U.K., have successfully driven revenue growth and
profitability.

A core element of Sammons Preston’s strategy is to maintain the most comprehensive single catalog of
rehabilitation products and supplies. The catalog, published for over 50 years, is considered the gold standard of
the industry and features the most comprehensive product offering with longstanding industry-leading positions
and recognized brand names.

Patterson Medical has an experienced sales force, national account contracts with major customer groups,

unmatched customer service within the industry and the proven ability to introduce new products each year,

21

allowing Patterson Medical to compete across the entire spectrum of the rehabilitation medical supplies and
non-wheelchair assistive products industry.

A key priority has been the expansion of the field sales force, which has grown by more than 45 sales
representatives since late in fiscal 2006 and now totals more than 200 worldwide. New sales representatives are
generally hired from the ranks of physical and occupational therapists, manufacturer representatives and others
with extensive industry knowledge.

Patterson Medical began developing a branch office structure in fiscal 2007 through a combination of
internal start-ups and dealer/distributor acquisitions. Similar to a dental branch, these offices have a showroom,
commissioned sales staff and service department that provides equipment installation, repair and warranty
service for equipment manufacturers. As of April 2009, 12 branches had been established.

Sammons Preston’s national accounts group collaborates with its sales force to meet the changing needs of

its expanding account base. The product management group works closely with customers, suppliers and the
sales force to evaluate new products for inclusion in Sammons Preston’s product offering. Sammons Preston
adds approximately 2,000 new products to the catalog each year. Sammons Preston’s U.S. national accounts
program is staffed by seasoned professionals who have developed a comprehensive portfolio of contracts.
Furthermore, the integrated Sammons Preston organization has national contracts with major purchasing groups
within each submarket, including hospitals, nursing homes and dealers.

For many years, Sammons Preston and SNR had the only national sales forces in the U.S. dedicated to the

clinical education and sale of products to institutionally based PTs and OTs. With the acquisition and integration
of SNR, Patterson Medical’s clinical presence and sales capability have been enhanced with a broader product
offering and a more complete range of proprietary brands. The Patterson Medical sales professionals, many of
whom are therapists, are located throughout the U.S. and Canada. These sales professionals have utilized the
extensive product line and the comprehensive national contracts portfolio to establish direct sales to U.S.
hospitals, nursing homes and rehab clinics. Patterson Medical also sells to national healthcare distributors and
local dealers.

The rehabilitation medical supplies and non-wheelchair assistive products that Patterson Medical offers are

generally not subject to direct reimbursement pressures from Medicare and Medicaid. Patterson Medical does not
engage in third-party billing and collection activities, but sells to customers, including dealers, who provide this
service.

The rehabilitation medical supplies and non-wheelchair assistive products industry is highly fragmented. No

one manufacturer, distributor or customer represents a significant portion of Patterson Medical’s revenue.

To enhance the total value it brings to its customers, Patterson Medical created a value-added benefit
program for its preferred customers. The Patterson Plussm program entitles its best customers to discount pricing
and cash rebates, priority service scheduling, supply management summary reports and continuing education
course discounts.

Distribution

Patterson Medical’s distribution process centers on its ability to fill small unit size and small dollar amount
orders. In the U.S., over 5,000 packages ship daily from five locations. A majority of products are shipped out of
an eastern Pennsylvania distribution center that is shared between all three Patterson operating units. Patterson
Medical moved into this facility during fiscal 2007, at which time an existing distribution center located in
Bolingbrook, Illinois was closed. Certain high volume product is distributed from other multi-segment facilities
within the Patterson Logistics distribution network. Approximately 95% of the packages in the U.S. ship via
UPS.

22

Patterson Medical’s call center operates from 7am – 7pm Monday through Friday, processing in excess of

4,000 calls per day. In addition, the customer can order 24 hours a day through Patterson Medical’s Internet
websites. The combination of in-house staff and web ordering options provide customers with 24 hours a day,
seven days a week ordering capabilities. Approximately 14% of customer orders are through the web. In
addition, fax orders and EDI capabilities support the larger, more technologically advanced customers, including
dealers, hospitals and long-term care facilities.

Sources of Supply

Among Patterson Medical’s core strengths is its ability to obtain premier products from vendors. Patterson

Medical purchases its products from over 2,000 suppliers and manufacturers. Although no single supplier
accounted for more than 5% of Patterson Medical’s total purchases in fiscal 2009, Patterson Medical frequently
is the largest single customer of these manufacturers. Suppliers view the ability to distribute their products
through Sammons Preston and Homecraft positively due to reputation, longstanding industry-leading position,
comprehensive catalogs, national account contracts, and sales force presence and distribution capabilities.
Patterson Medical continually works at strengthening its supplier relationships through the introduction of
supplier programs.

Competition

Patterson Medical believes it is the only national player to offer, “one-stop shopping” to its customers.

Patterson Medical’s competition is generally highly fragmented, locally or regionally focused and without the
product offering necessary to be a one-stop shop. Patterson Medical’s national and international scale and
purchasing power provide Patterson Medical with a favorable cost position and strong pricing trends relative to
its competition.

For further information on each of the Company’s three operating segments, and operations by geographic

area, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 of
this document and Note 11 to the Consolidated Financial Statements.

Patterson Companies, Inc.

Trademarks

Patterson has registered with the United States Patent and Trademark Office the trademarks “Patterson®,”

“PDXpress®,” “EagleSoft® “ and “eMagine®.” With the addition of Patterson Medical, the Company acquired the
marks Sammons, Preston, Roylan, Homecraft and numerous other tradenames and trademarks. The Company
believes that these trademarks are well recognized within their respective industries, and are therefore valuable
assets of the Company.

Employees

As of April 25, 2009, the Company had approximately 7,010 employees. Patterson has not experienced a
shortage of qualified personnel in the past, and believes that it will be able to attract such employees in the future.
None of Patterson’s employees are subject to collective bargaining agreements or represented by a union. The
Company considers its relations with its employees to be good.

Governmental Regulation

The marketing, distribution and sale of certain products sold by the Company are subject to the

requirements of various federal, state and local laws and regulations. The Company is subject to regulation by the
Federal Food and Drug Administration, the Drug Enforcement Administration and the U.S. Department of
Transportation. Among the federal laws which impact the Company are the Federal Food, Drug and Cosmetic
Act, which regulates the advertising, record keeping, labeling, handling, storage and sale of drugs and medical
devices which are distributed by the Company, and which requires the Company to be registered with the Federal
Food and Drug Administration; the Safe Medical Devices Act, which imposes certain reporting requirements on
the Company in the event of an incident involving serious illness, injury or death caused by a medical device
distributed by the Company; and the Controlled Substance Act, which regulates the record keeping, handling,
storage and sale of certain drugs sold by the Company, and which requires the Company to be registered with the
Drug Enforcement Administration. In addition, the transportation of certain products distributed by the Company
that are considered hazardous materials is subject to regulation by the U.S. Department of Transportation.

The Company also is required to be licensed as a distributor of drugs and medical devices by each state in

which it conducts business. In addition, several state Boards of Pharmacy require the Company to be licensed in
their state for the sale of animal health products within their jurisdiction. The Company is also subject to the
requirements of foreign laws and regulations, which impact the Company’s operations in those foreign countries
where the Company conducts business.

While the Company believes it is in substantial compliance with the laws and regulations which regulate its

business, and that it possesses all the licenses required in the conduct of its business, the failure to comply with
any of those laws or regulations, or the imposition of new laws or regulations could negatively impact the
Company’s business.

Background of Executive Officers

James W. Wiltz was named the Company’s Chief Executive Officer in May 2005. Mr. Wiltz had held the

position of President and Chief Operating Officer since April 2003. Upon being elected Chief Executive Officer,
Mr. Wiltz retained the title of President, however the Company eliminated the Chief Operating Officer position.
Mr. Wiltz also served as a Vice President of the Company from 1986 to 2003 and as President of Patterson
Dental Supply, Inc., from 1996 to 2003. Patterson has employed him since September 1969, initially as a
territory sales representative. Mr. Wiltz was appointed to the Board of Directors in March 2001.

Peter L. Frechette currently serves as our Chairman of the Board and has held that position since May of

Item 1A. RISK FACTORS

The following list describes several risk factors that are unique to our company. The risk factors described

below should be carefully considered, together with the information included elsewhere in this Annual Report on

25

Form 10-K and other documents filed with the SEC. These risks factors are being disclosed based on instructions
set forth in Item 503(c) of Regulation S-K.

Economic conditions and volatility in the financial markets could adversely affect our operating results
and financial condition.

Continued recessionary trends in the U.S. or global economy, or an uncertain economic outlook, could
materially adversely affect our operating results and financial condition in the future. Economic conditions may
continue to cause customers to reduce or delay purchases from us and may cause vendors to reduce their
production or change their terms of sale to us. Volatility and other disruptions in the financial markets could
adversely affect the cost and availability of credit to us, as well as the cost of, and ability to, sell finance contracts
we receive from customers to outside financial institutions.

We compete in distribution industries that are highly competitive and we may not be able to compete
successfully.

Our competitors include numerous manufacturers and distributors. Some of our competitors may have
different resources than we do, which could allow them to compete more successfully. Many of our products are
available from several resources and our customers tend to have relationships with several different distributors.
Competitors could obtain exclusive rights to market particular products, which we would then be unable to
market. Our failure to compete effectively may limit and/or reduce our revenues, profitability and cash flow.

Acquisitions of businesses could negatively impact our profitability and return on invested capital.

As a part of our business strategy, we have acquired businesses in the ordinary course and expect to

continue acquiring businesses in the future. These acquisitions can involve a number of risks and challenges, any
of which could cause significant operating inefficiencies and adversely affect our growth and profitability. Such
risks and challenges include underperformance relative to our expectations and the price paid for the acquisition;
unanticipated demands on our management and operational resources; difficulty in integrating personnel,
operations and systems; retention of customers of the combined businesses; assumption of contingent liabilities;
and acquisition-related earnings charges.

Our international operations are subject to risks that could adversely affect our operating results.

There are a number of risks inherent in foreign operations, which include regulatory, economic and political
requirements and changes. Additionally, foreign operations expose us to foreign currency fluctuations that could
impact our results of operations and financial condition based on the movements of the applicable foreign
currency exchange rates in relation to the U.S. Dollar.

Our future operating results can be affected by our relationships with our sales representatives and
vendors and manufacturers of products that we distribute.

The inability to attract or retain qualified sales personnel or build or maintain relationships with vendors and
manufacturers of products that we distribute may have an adverse effect on our business.

We sell products that could be subject to market and technological obsolescence.

We carry over 100,000 different product stock keeping units. Some of these products are subject to technological
obsolescence that may not be within the control of the Company since we do not manufacture the products. If we
were no longer able to sell these products due to customers making decisions not to buy them, we may have to
record expense related to the diminution in value of inventories we have in stock that would adversely impact our
operating results.

26

Audits by tax authorities could result in additional tax payments for prior periods.

The amount of income taxes we pay is subject to ongoing audits by U.S. federal, state and local tax authorities
and by non-U.S. tax authorities. If these audits result in assessments different from our reserves, our future
results may include unfavorable adjustments to our tax liabilities.

We are subject to a variety of litigation that could adversely affect our results of operations and financial
condition.

We are subject to a variety of litigation incidental to our business, including claims for damages arising out

of the use of products we distribute, claims relating to intellectual property matters, and claims involving
employment matters. We are also subject to securities litigation.

The defense of these lawsuits may divert our management’s attention, we may incur significant expenses in

defending these lawsuits, and we may be required to pay damage awards or settlements or become subject to
equitable remedies that could adversely affect our financial condition and results of operations. Any insurance or
indemnification rights that we may have may be insufficient or unavailable to protect us against potential loss
exposures.

Leadership Development and Succession Planning

Our business could suffer if it loses key personnel unexpectedly or fails to provide for an orderly
management succession. Our success depends, in large part, on our ability to recruit skilled personnel for the
business, and then identify and train our personnel for their transition into key roles to support the long-term
growth of the business. While our board of directors and management actively monitor our succession plan and
processes, any sudden change at the senior management level may adversely affect our business.

We may be required to record a significant charge to earnings if our goodwill or other intangible assets
become impaired.

Our balance sheet includes goodwill and other identifiable intangible assets. Under U.S. generally accepted
accounting principles, if impairment of our goodwill or other identifiable intangible assets is determined we may
be required to record a significant charge to earnings in the period of such determination.

We are exposed to the risk of changes in interest rates.

Our balance sheet includes variable rate long-term debt and certain non-current assets that are sensitive to
movements in short-term interest rates. The variable rates are comprised of LIBOR plus a spread and reset on
certain dates, as prescribed by the respective agreements. In addition, our balance sheet includes fixed rate long-
term debt, whose fair value could be adversely affected by movements in interest rates.

Item 1B. UNRESOLVED STAFF COMMENTS

The Company has received no written comments regarding our periodic or current reports from the staff of

the SEC that were issued 180 days or more preceding the end of our 2009 fiscal year that remain unresolved.

Item 2.

PROPERTIES

The Company owns its principal executive offices in St. Paul, Minnesota, and the majority of its distribution

and manufacturing facilities. Leases of other distribution, manufacturing and administrative facilities generally
are on a long-term basis, expiring at various times, with options to renew for additional periods. Most sales
offices are leased for varying and usually shorter periods, with or without renewal options. The Company

27

believes its properties are in good operating condition and are suitable for the purposes for which they are being
used.

Patterson Logistics Services

Effective at the beginning of fiscal 2007, the majority of the assets used to distribute product that were

previously owned and operated by individual business units were transferred to a wholly owned subsidiary of
Patterson Companies, Inc. The new entity, Patterson Logistics Services, Inc. (“PLSI”) operates the distribution
function for the benefit of all three of the sales and marketing business units.

As of April 25, 2009, PLSI operates 17 distribution centers totaling approximately 900,000 square feet of

distribution space as follows:

• One dental distribution center located in Indiana.

• Eight veterinary distribution centers. Sales and administrative personnel for the veterinary segment
generally share space with PLSI in these distribution facilities, which are located in Alabama,
Colorado, Florida, Indiana, Kentucky, Massachusetts and Texas.

• One rehabilitation distribution center in New York State.

• Two distribution centers located in Florida and Texas, which stock and distribute both dental and

rehabilitation product.

• Three distribution centers which stock and distribute dental and veterinary products, located in Iowa,

South Carolina and Washington state; and,

• Two distribution centers located in California and Pennsylvania which distribute product for all three

of the business units. These locations replaced nearby distribution centers which distributed product of
just one of the business units.

Approximately 80% of the PLSI distribution center space is owned.

Dental Supply

In addition to the locations operated by PLSI, Patterson Dental utilizes two owned locations in Illinois used

to manufacture and ship printed office products, and to operate the Patterson Technology Center. The dental sales
operations in Canada are supported by distribution centers located in Quebec and Alberta, Canada.

The dental supply segment is headquartered in the Company’s principal executive offices. This segment also
maintains sales and administrative offices inside the United States at approximately 90 locations in over 40 states
and at 10 locations in Canada. The majority of these locations are leased.

Veterinary Supply

Headquartered in Sterling, Massachusetts, Webster Veterinary’s sales and administrative personnel

generally reside within the PLSI distribution center locations.

Rehabilitation Supply

Patterson Medical is headquartered in Bolingbrook, Illinois. Distribution of product in North America is

generally performed at PLSI-operated locations. Domestically, the rehabilitation supply segment maintains
manufacturing facilities in Wisconsin, New York and South Carolina. Over the past three years, 12 branch
offices have been established through acquisitions and internal start-ups. Four of these branch offices are in a
shared location with Patterson Dental branches. The majority of these locations are leased.

Internationally, this segment has facilities located in the U.K., France and Canada.

28

Item 3.

LEGAL PROCEEDINGS

The Company is involved in various product related, employment related and other legal proceedings
arising in the ordinary course of business. Some of these proceedings involve product liability claims arising out
of the use of products the Company distributes. Product liability indemnification is generally obtained from our
suppliers. However, in the event a supplier of a defective product is unable to pay a judgment for which the
Company may be jointly liable, the Company would have liability for the entire judgment.

The Company maintains product liability insurance coverage for any potential liability for claims arising out

of products sold by the Company. While the Company believes its insurance coverage is adequate, there can be
no assurance that the insurance coverage maintained is sufficient or will be available to us in adequate amounts
or at reasonable costs in the future. Also, there can be no assurance that the indemnification agreements we have
with our suppliers will provide us with adequate protection. In addition, future claims brought against the
Company could involve claims not covered by insurance or indemnification agreements, and could have a
material adverse effect on the Company’s business or financial condition.

As of April 25, 2009 and April 26, 2008, the Company had accrued our best estimate of potential losses

relating to product liability and other claims that were probable to result in a liability and for which it was
possible to reasonably estimate a loss. These accrued amounts, as well as related expenses, have not been
material to the Company’s financial position, results of operations or cash flows. Our method for determining
estimated losses considers currently available facts, presently enacted laws and regulations and other external
factors, including probable recoveries from third parties.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

Overview

The Company’s fiscal 2009 financial information is summarized in this Management’s Discussion and
Analysis, the Consolidated Financial Statements, and the related Notes. The following background is essential to
more fully understand the Company’s financial information.

Patterson operates a distribution business in three complementary markets: dental supply, veterinary supply

and rehabilitation supply. Historically the Company’s strategy for growth focused on internal growth and the
acquisition of smaller distributors and businesses offering related products and services to the dental market. In
fiscal 2002, the Company expanded its strategy to take advantage of a parallel growth opportunity in the
veterinary supply market by acquiring the assets of J. A. Webster, Inc. on July 9, 2001. The Company added a
third component to its business platform in fiscal 2004 when it entered the rehabilitation supply market with the
acquisition of AbilityOne Products Corp. (“AbilityOne”) on September 12, 2003. AbilityOne is now known as
Patterson Medical.

Operating margins of the veterinary business are considerably lower than the dental and rehabilitation
supply businesses. While operating expenses run at a lower rate in the veterinary business, its gross margin is
substantially lower. Over the past two years, the veterinary business has grown at a faster rate than the other two
businesses, resulting in dilution of the consolidated operating margin.

There are several important aspects of the Company’s business that are useful in analyzing the Company,

including: (1) market growth in the various markets it operates; (2) internal growth; (3) growth through
acquisition; and (4) continued focus on controlling costs and enhancing efficiency. Management defines “internal
growth” as the increase in net sales from period to period, excluding the impact of changes in currency exchange
rates, and excluding the net sales, for a period of twelve months following the transaction date, of businesses that
it has acquired.

During fiscal 2008, the Company executed a series of transactions that effectively changed our capital
structure, lowering our weighted average cost of capital by almost 100 basis points, and positioned the Company
to increase returns to our shareholders. First, the Company repurchased approximately 18 million shares of its
common stock on the open market and through an accelerated share repurchase agreement for approximately
$636 million. A portion of the funding for the share repurchases came from debt issued in the fourth quarter of
fiscal 2008, consisting of fixed-rate private placement notes totaling $450 million and a variable-rate term loan of
$75 million.

Fiscal 2009 Compared to Fiscal 2008

Net Sales. Fiscal 2009 consolidated sales were $3,094.2 million, an increase of 3.2% compared to $2,998.7
million in fiscal 2008. Acquisitions contributed 3.8% to sales growth, resulting primarily from an acquisition by
the veterinary unit. Fluctuations in foreign currency translation rates reduced sales by 1.1%. During fiscal 2009,
sales at each of our business units were adversely affected by the economic recession. The Company believes the
weakness in the general economy will continue to affect our performance in fiscal 2010.

Sales of our consolidated dental supply unit totaled $2,174.4 million, a decrease of 0.3% from $2,181.3
million in fiscal 2008. Acquisitions had a positive impact on sales of 0.9%, while fluctuations in foreign currency
rates related to our dental operations in Canada reduced sales by 1.0%. Sales of dental consumable supplies of
$1,217.2 million were virtually unchanged from fiscal 2008. In the first half of fiscal 2009, an economy-related
trend of patients deferring higher-level and discretionary services began and continued throughout the year.

Dental equipment sales declined 1.7% in fiscal 2009, including a 2.0% decrease in basic equipment. Sales of

CEREC® 3D dental restorative systems were 0.7% lower in fiscal 2009, but did grow 5.7% in the second half of
fiscal 2009 as compared to the second half of fiscal 2008. CEREC system sales in the second half of the year
benefitted from promotional financing arrangements that were made available to qualified customers, as well as
the January 2009 introduction of a new digital image acquisition unit by the manufacturer, Sirona Dental
Systems, which provides significantly greater ease of use and imaging precision.

Other dental sales, consisting primarily of technical service parts and labor, software support services and

artificial teeth, grew 3.2% in fiscal 2009.

Webster Veterinary fiscal 2009 sales of $550.6 million increased 23.3% from $446.4 million in fiscal 2008.

Acquisitions, primarily the Columbus Serum Company (“Columbus”) acquired in October 2008, contributed
19.7% of the sales growth. During the second half of the year, veterinary clinics were negatively affected by the
contracted economy.

Sales declined 0.5% at Patterson Medical, including a negative impact of 2.9% related to foreign currency
rates. The impact of currency on sales growth was partially offset by a contribution of 1.6% from acquisitions.

Gross Margin. Consolidated gross margin declined 70 basis points to 33.7% due to the Veterinary unit’s
sales representing a larger percentage of consolidated sales in fiscal 2009. Since Veterinary gross margins are
lower than the other two business units, the increase in Veterinary’s sales as a percentage of consolidated sales
has a dilutive impact on the consolidated gross margin. In addition, the gross margin of Columbus is somewhat
lower than the historical Webster Veterinary gross margin.

The Dental segment’s gross margin was unchanged from fiscal 2008.

Gross margin of the Veterinary unit declined 110 basis points in fiscal 2009, due mostly to lower levels of

vendor rebates earned and the lower Columbus gross margins. The negative impact of Columbus on gross margin
is expected to moderate as the business becomes fully integrated.

Patterson Medical’s gross margin improved 40 basis points, due mostly to better freight management and

product pricing.

Operating Expenses. The consolidated operating expense ratio in fiscal 2009 was 22.5%, or 10 basis points
higher than fiscal 2008. Beginning the third quarter of fiscal 2009, the Company began taking steps related to a
range of cost control initiatives including a hiring freeze except in the area of sales representatives, a wage freeze
and restrictions on travel.

Operating expenses as a percent of sales at the Dental unit increased 70 basis points, reflecting lost leverage

on lower than planned sales. The Veterinary unit’s operating expense ratio improved 30 basis points due

34

primarily to the Columbus business, which had a somewhat lower operating expense ratio as compared to that of
the historical Veterinary unit’s operations.

Patterson Medical’s operating expense ratio was 50 basis points lower in fiscal 2009. In addition to the

impact of expense control initiatives, the impact of added infrastructure expense at the branch locations added
over the past three years has dissipated as the locations have become more established.

Operating Income. Operating income was $346.2 million in fiscal 2009, down $13.0 million, or 3.6%, from

$359.2 million in fiscal 2008. Operating margin was 11.2% and 12.0% in fiscal years 2009 and 2008,
respectively.

Interest Expense. Interest expense was $30.1 million compared to $12.8 million in fiscal 2008. In March

2008, the Company issued $525 million of long-term debt which resulted in the higher level of interest expense
in fiscal 2009.

Other Income, net. Other income, net of other expenses, was $3.6 million compared to $11.0 million in
fiscal 2008. Interest income decreased $4.3 million due primarily to a decline in interest rates on cash and cash
equivalents.

Income Taxes. The effective income tax rate was 37.5% in fiscal 2009 as compared to 37.1% in fiscal 2008.

Net Income and Earnings Per Share. Net income declined 11.2% to $199.6 million due to a decrease in
operating income and an increase in interest expense. Share repurchase activity in the second half of fiscal 2008
resulted in a decrease in shares outstanding in fiscal 2009. Earnings per diluted share and dilutive shares
outstanding were $1.69 and 118.4 million, respectively, in fiscal 2009 and $1.69 and 132.9 million, respectively,
in fiscal 2008.

Fiscal 2008 Compared to Fiscal 2007

Net Sales. Consolidated sales in fiscal 2008 totaled $2,998.7 million, an increase of 7.2% compared to

$2,798.4 million in fiscal 2007. Foreign currency translation rates contributed one percentage point and
acquisitions contributed 0.6% to the sales growth in fiscal 2008.

Sales of our dental supply unit increased 5.7% to $2,181.3 million. Sales of dental consumable supplies
grew 5.5%. Dental equipment sales grew 4.2%, including basic equipment growth of 4.3%. Sales of CEREC® 3D
dental restorative systems rose 3.7%.

Other dental sales, consisting primarily of technical service parts and labor, software support services and

artificial teeth, grew 11.7% in fiscal 2008.

Webster Veterinary sales grew 11.8% to $446.4 million from $399.4 million. In January 2007, Webster

made a strategic decision to drop a line of products previously sold under an agency agreement, including flea/
tick and heartworm products, and replaced them with fully distributed product offerings from several vendor
partners. This transition progressed throughout the year as planned, although there was a modest negative impact
to Webster’s operating metrics during the first half of fiscal 2008.

Sales growth of 11.0% at Patterson Medical included the contribution of new branch offices that have been
established by acquisition and greenfield expansion. As a part of its initiative to expand and strengthen its value-
added model, the rehabilitation unit opened 12 branch offices in selected markets throughout the United States
during fiscal 2008 and fiscal 2007. The November 2007 acquisition of PTOS software, a leading line of practice
management software for physical therapists, enables Patterson Medical to create relationships with new
customers and deepen relationships with existing customers.

35

Gross Margin. Consolidated gross margin of 34.4% was 20 basis points lower in fiscal 2008 due to declines

at Patterson Medical and Webster Veterinary. In addition, the sales growth of Webster outpaced both the dental
and rehabilitation segments, resulting in a dilutive impact to consolidated gross margin.

The Dental segment’s gross margin was flat, despite approximately $2 million of expense related to a
distribution agreement fee which began to be amortized in October 2007. In addition, local currency pricing in
Canada was lowered in the third quarter of fiscal 2008 in response to the strengthening of the Canadian dollar
compared to the United States dollar.

Gross margin decreased by 50 basis points in fiscal 2008 at the Veterinary unit. This was largely a result of
the decision to terminate an agency relationship late in the third quarter of fiscal 2007, as replacement offerings
for the products previously sold under the agency relationship are now being fully distributed.

Patterson Medical’s gross margin declined 20 basis points, due mostly to higher freight costs in the early
part of fiscal 2008. In the second half of the year, better freight management and product pricing mitigated much
of the higher freight costs.

Operating Expenses. The consolidated operating expense ratio improved 20 basis points to 22.4%.

Operating expenses as a percent of sales at the Dental unit decreased 30 basis points, reflecting the leverage
of infrastructure investments over the past two years and the elimination of duplicate costs from the distribution
system. The operating expense ratio of the Veterinary unit declined 50 basis points due both to leverage on
higher sales volume and distribution system realignment, including the closing of a stand-alone warehouse.

Patterson Medical’s operating expense ratio was 100 basis points higher in fiscal 2008, resulting from the

infrastructure expense of adding branch locations through both acquisition and internal startups.

Operating Income. Operating income was $359.2 million or 12.0% of net sales in fiscal 2008. This amount

represents an increase of 7.0% from $335.7 million in fiscal 2007. Operating margin in fiscal 2007 was also
12.0%.

Interest Expense. Interest expense was $12.8 million compared to $14.2 million in fiscal 2007. The average

debt balance carried for the majority of fiscal 2008 was lower than in fiscal 2007, resulting in the decrease in
interest expense.

Other Income, net. Other income, net of other expenses, increased to $11.0 million from $8.1 million due to

higher levels of interest income and foreign currency transaction gains.

Income Taxes. The effective income tax rate was 37.1% in fiscal 2008, slightly higher than a rate of 36.8%

in the prior year.

Net Income and Earnings Per Share. Net income increased 7.9% to $224.9 million. Earnings per diluted
share of $1.69 represents an increase of $0.18 or 11.9% from the $1.51 earnings per share reported in fiscal 2007.
Approximately 18 million shares of common stock were repurchased in the second half of fiscal 2008.

Liquidity and Capital Resources

Patterson’s operating cash flow has been the Company’s principal source of liquidity in the last three fiscal

years. The issuance of $525 million of debt in the March 2008 was used primarily to repurchase shares of the

36

Company’s common stock. During fiscal 2009, the Company used its revolving credit facility periodically as a
source of liquidity in addition to operating cash flow.

Operating activities generated cash of $124.0 million in fiscal 2009, compared with $265.4 million in fiscal

2008 and $243.5 million in fiscal 2007. In the second half of fiscal 2009, the Company invested in a financing
program to support marketing efforts directed at the CEREC product line. This promotion, which ended at the
close of fiscal 2009, generated approximately $98 million of finance contracts that the Company could not
immediately sell to our funding sources due to certain requirements in those funding arrangements. The
Company expects to fully liquidate these contracts in fiscal 2010, resulting in an incremental $98 million of cash
flow in the year.

Capital expenditures were $32.3, $36.0 and $19.5 million in fiscal years 2009, 2008 and 2007, respectively.

Fiscal 2009 and 2008 significant expenditures included the expansion of our general office building and the
expansion of existing distribution facilities to accommodate multiple business units, in addition to continuing
investments in information systems. At April 25, 2009, one distribution facility expansion in Florida remains in
progress.

The Company expects to invest approximately $25 million in capital expenditures during fiscal 2009,
including the completion of the distribution center project in progress as of April 25, 2009 and investments in
information systems.

Cash used for acquisitions totaled $124.8 million in fiscal 2009. The acquisitions of the Columbus Serum

Company and Dolphin Imaging Systems, LLC and Dolphin Practice Management, LLC accounted for the
majority of the cash used.

Payments on long-term debt in fiscal 2009 were $130 million and related to a scheduled retirement of debt
that had been issued in fiscal 2004. As of April 25, 2009, $22 million was outstanding under a revolving credit
facility which expires in fiscal 2013. A maximum of $300 million is available under this facility.

As noted above in March 2008, the Company closed on $525 million of long-term debt financing which was

comprised of $450 million of fixed-rate private notes with maturities of five, seven and 10 years in addition to a
$75 million five-year term loan at a floating rate of interest through a group of banks. The Company used $250
million of the debt financing to repurchase shares under an accelerated share repurchase agreement (“ASR”). The
remaining proceeds from the debt issuances were used to repay borrowings under the Company’s revolving
credit agreement and for general corporate purposes.

During the second half of fiscal 2008, the Company purchased shares of its common stock on the open
market, under a 25 million share repurchase program authorized by the board of directors. In the fourth quarter of
fiscal 2008, the Company entered into an ASR under which it paid $250 million and took an initial delivery of
6.3 million shares. In total, the Company repurchased approximately 18 million shares for $636.1 million during
fiscal 2008. Under the terms of the ASR, the Company could have received additional shares, or could have been
required to pay the counterparty in the form of either cash or shares. The final settlement of the ASR occurred in
June 2008, with an additional 1.1 million shares delivered to the Company. As of April 25, 2009, 5.9 million
shares can be repurchased under the current authorization by the board of directors, which expires on
December 31, 2012. Going forward, in the absence of desirable acquisition opportunities, the Company would
likely return excess cash to its shareholders through additional open market purchases of its common stock, or
may consider initiating a dividend strategy.

Management expects funds generated from operations and existing cash to be sufficient to meet the
Company’s working capital needs for the next fiscal year. The Company expects to continue to obtain liquidity
from the sale of its equipment finance contracts, including the $98 million of finance contracts generated during
fiscal 2009. In addition, as of April 25, 2009, $278 million is available under a revolving credit facility. The

37

Company’s existing debt facilities are believed to be adequate as a supplement to internally generated cash flows
to fund anticipated expansion plans and strategic initiatives.

The Company sells a significant portion of its installment sale contracts to a commercial paper funded

conduit managed by a third party bank, and as a result, commercial paper is indirectly an important source of
liquidity for the Company. The Company is allowed to participate in the conduit due to the quality of its finance
contracts and its financial strength. Cash flow could be impaired if the Company’s financial strength diminished
to a level that precluded the Company from taking part in this facility or other similar facilities. Also, market
conditions outside of the Company’s control could adversely affect the ability of the Company to sell the
contracts.

Customer Financing Arrangements

The Company is a party to two arrangements under which it sells finance contracts it receives from its
customers to outside financial institutions. These arrangements currently provide sources of liquidity for the
Company that would have to be replaced should the current financial institutions be unable or unwilling to
continue in the arrangements. The Company’s financing business is described in further detail in Note 6 of the
Notes to the Consolidated Financial Statements in Item 8 of this Form 10-K. Note 6, “Customer Financing”,
discusses the nature and business purpose of the arrangements and the activity under each arrangement during
fiscal 2009, including the amount of finance contracts sold and residual interests held by the Company.

As discussed in Note 11 of the Notes to the Consolidated Financial Statements, the Company adopted the

provisions of FIN 48 at the beginning of fiscal 2008. The Company is unable to determine its contractual
obligations by year related to this pronouncement, as the ultimate amount or timing of settlement of its reserves
for income taxes cannot be reasonably estimated. The total liability for unrecognized tax benefits including
interest and penalties as of April 25, 2009, is $20.7 million.

In addition, the Company is contractually committed to approximately $6 million of capital expenditures
relating to a distribution facility construction project that is in-process as of April 25, 2009. For a more complete
description of our contractual obligations, see Notes 7 and 10 to the Consolidated Financial Statements in Item 8
of this Form 10-K.

Outlook

Over the last 10 years, the Company has been able to grow revenue and earnings through its strategy of
emphasizing its value-added, full-service capabilities, using technology to enhance customer service, continuing
to improve operating efficiencies, and growing through internal expansion and acquisitions. While we believe
that the weakness in the general economy that existed throughout much of fiscal 2009 will continue to affect our
performance for at least several more quarters, the Company’s strategy will continue to focus on these key
elements. With strong operating cash flow and available credit capacity, the Company is confident that it will be
able to financially support its future growth. The strategic initiatives that the Company has implemented in the

38

past several years, as well as those that will be implemented in fiscal 2010 and beyond, will strengthen the
Company’s operational platform and contribute to future growth. Given these factors, the Company considers
itself well positioned to capitalize upon the growth opportunities in the dental supply, companion-pet veterinary
supply and the worldwide rehabilitation supply markets.

(1) Receivables as of April 25, 2009 include approximately $98 million of finance contracts received from
customers related to a financing promotion. The Company expects to sell these contracts to outside
institutions under existing agreements during fiscal 2010. If these finance contracts are excluded from the
calculation of DSO, the pro forma DSO would be 44.

(2) The inventory values used in this calculation are the LIFO inventory values for all inventories except for
manufactured inventories and foreign inventories, which are valued using FIFO inventory methods.

Foreign Operations

Foreign sales are derived primarily from Patterson Dental and Patterson Medical operations in Canada and

from Patterson Medical’s operations in the U.K. and France. Fluctuations in currency exchange rates have not
significantly impacted earnings. However, changes in exchange rates adversely affected net sales in fiscal 2009
and enhanced net sales in fiscal 2008 and 2007. Without foreign currency effects, net sales would have been
$33.4 million higher, $27.0 million lower and $12.3 million lower in fiscal years 2009, 2008 and 2007,
respectively. Changes in currency exchange rates are a risk accompanying foreign operations, but this risk is not
considered material with respect to the consolidated operations of the Company.

Critical Accounting Policies and Estimates

The Company has adopted various accounting policies to prepare its consolidated financial statements in
accordance with accounting principles generally accepted in the United States. Management believes that the
Company’s policies are conservative and its philosophy is to adopt accounting policies that minimize the risk of
adverse events having a material impact on recorded assets and liabilities. However, the preparation of financial
statements requires the use of estimates and judgments regarding the realization of assets and the settlement of
liabilities based on the information available to management at the time. Changes subsequent to the preparation
of the financial statements in economic, technological and competitive conditions may materially impact the
recorded values of the Company’s assets and liabilities. Therefore, the users of the financial statements should
read all the notes to the Consolidated Financial Statements and be aware that conditions currently unknown to
management may develop in the future. This may require a material adjustment to a recorded asset or liability to
consistently apply the Company’s significant accounting principles and policies that are discussed in Note 1 to
the Consolidated Financial Statements. The financial performance and condition of the Company may also be
materially impacted by transactions and events that the Company has not previously experienced and for which
the Company has not been required to establish an accounting policy or adopt a generally accepted accounting
principle.

Revenue Recognition—Our revenue recognition processes involve establishing estimates for returns,

damaged goods, rebates and other revenue allowances. These estimates are based on historical experience and the

39

facts known at the date of the preparation of the financial statements, but future events could cause actual results
to vary from our estimates.

Inventory and Reserves—Inventory consists primarily of merchandise held for sale and is stated at the lower

of cost or market. Cost is determined using the last-in, first-out (LIFO) method for all inventories, except for
foreign inventories and manufactured inventories, which are valued using the first-in, first-out (FIFO) method.
The Company continually assesses the valuation of our inventories and reduces the carrying value of those
inventories that are obsolete or in excess of our forecasted usage to estimated realizable value. Estimates are
made of the net realizable value of such inventories based on analyses and assumptions including, but not limited
to, historical usage, future demand and market requirements.

Goodwill and Other Indefinite-Lived Intangible Assets—Goodwill represents the excess of cost over the fair
value of identifiable net assets of businesses acquired. Other indefinite-lived intangible assets include copyrights,
trade names and trademarks.

The Financial Accounting Standards Board’s (“FASB”) Statement of Financial Accounting Standards
(“SFAS”) No. 142, “Goodwill and Other Intangible Assets” (“SFAS No. 142”), requires that goodwill for each
reporting unit be reviewed for impairment at least annually. The Company has three reporting segments at
April 25, 2009, which are the same as our operating units. The Company tests goodwill for impairment using the
two-step process prescribed in SFAS No. 142.

Fair value is determined using valuation techniques, including discounted cash flows and market multiple
analyses. These types of analyses contain uncertainties because they require management to make assumptions
and to apply judgment to estimate industry economic factors and the profitability of future business strategies.
The Company conducts impairment testing based on our current business strategy in light of present industry and
economic conditions, as well as future expectations.

In the fourth quarter of fiscal 2009, management completed its annual goodwill and other indefinite-lived

intangible asset impairment tests and determined there was no impairment. Although the Company believes our
estimates and assumptions used in estimating cash flows and determining fair value are reasonable, making
material changes to such estimates and assumptions could materially affect such impairment analyses and our
financial results, including an impairment charge that could be material.

Long-Lived Assets—Long-lived assets, including definite-lived intangible assets, are evaluated for

impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not
be recoverable through the estimated undiscounted future cash flows derived from such assets. The Company’s
definite-lived intangible assets primarily consist of an exclusive distribution agreement and customer lists. When
impairment exists, the related assets are written down to fair value.

Income Taxes—The Company is subject to income taxes in both the U.S. and numerous foreign

jurisdictions. Significant judgments are required in determining the consolidated provision for income taxes.

During the ordinary course of business, there are many transactions and calculations for which the ultimate
tax determination is uncertain. As a result, the Company recognizes tax liabilities based on estimates of whether
additional taxes and interest will be due. These tax liabilities are recognized when, despite the Company’s belief
that its tax return positions are supportable, the Company believes that certain positions may not be fully
sustained upon review by tax authorities. The Company believes that its accruals for tax liabilities are adequate
for all open audit years based on its assessment of many factors including past experience and interpretations of
tax law. This assessment relies on estimates and assumptions and may involve a series of complex judgments
about future events. To the extent that the final tax outcome of these matters is different than the amounts
recorded, such differences will impact income tax expense in the period in which such determination is made and
could materially affect our financial results.

40

To the extent that the provision for income taxes would have increased/decreased by 1 percent of income

before taxes, consolidated net income would have decreased/increased $3.2 million in fiscal 2009.

Share-based Compensation—The Company accounts for share-based payment awards in accordance with
SFAS No. 123(R). The Company recognizes share-based compensation based on certain assumptions including
inputs within the Black-Scholes Model and estimated forfeitures. These assumptions require subjective judgment
and changes in the assumptions can materially affect fair value estimates. Management assesses the assumptions
and methodologies used to estimate forfeitures and to calculate estimated fair value of share-based compensation
on a regular basis. Circumstances may change, and additional data may become available over time, which could
result in changes to these assumptions and methodologies and thereby materially impact our fair value
determination or estimates of forfeitures. If factors change and the Company employs different assumptions in
the application of SFAS No. 123(R), the amount of compensation expense associated with SFAS No. 123(R)
may differ significantly from what was recorded in the current period.

Recent Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial
Accounting Standards (“SFAS”) No. 157, “Fair Value Measurements” (“SFAS No. 157”), which defines fair
value, provides a framework for measuring fair value, and expands the disclosures required for assets and
liabilities measured at fair value. SFAS No. 157 applies to existing accounting pronouncements that require fair
value measurements, but it does not require any new fair value measurements. In February 2008, the FASB
issued Staff Position FAS 157-2, which deferred the effective date of SFAS No. 157 as it relates to nonfinancial
assets and liabilities. The Company adopted the disclosure requirements of the effective portions of SFAS No.
157 at the beginning of fiscal 2009. The Company is evaluating the impact of the remaining portions of SFAS
No. 157, which are effective at the beginning of our fiscal year 2010.

In February 2007, the FASB issued Statement No. 159, “The Fair Value Option for Financial Assets and
Financial Liabilities” (“SFAS 159”), which permits entities to choose to measure many financial instruments and
certain other items at fair value. The Company adopted SFAS No. 159 beginning the first quarter of fiscal 2009,
but did not elect the fair value option for any of its financial assets or liabilities.

In March 2008, the FASB issued Statement No. 161, “Disclosures about Derivative Instruments and

Hedging Activities, an amendment of FASB Statement No. 133” (“SFAS No. 161”). SFAS No. 161 requires
enhanced disclosures about derivatives and hedging activities and was adopted in the fourth quarter of fiscal
2009. Since SFAS No. 161 requires only additional disclosures concerning derivatives and hedging activities, the
adoption of SFAS No. 161 did not have a material impact on our consolidated financial statements.

In December 2007, FASB issued Statement No. 141(revised 2007), “Business Combinations” (“SFAS
No. 141(R)”). SFAS No. 141(R) significantly changes the accounting for business combinations in a number of
areas including the treatment of contingent consideration, preacquisition contingencies, transaction costs,
in-process research and development and restructuring costs. In addition, under SFAS No. 141(R), changes in an
acquired entity’s deferred tax assets and uncertain tax positions after the measurement period will impact income
tax expense. SFAS No. 141(R) is effective for fiscal years beginning after December 15, 2008 and will change
our accounting treatment for business combinations on a prospective basis.

In June 2009, the FASB issued Statement No. 166, “Accounting for Transfers of Financial Assets-an

Amendment of FASB Statement No. 140” (“SFAS No. 166”) and Statement No. 167, “Amendments to FASB
Interpretation No. 46(R)” (“SFAS No. 167”). SFAS No. 166 will require more information about transfers of
financial assets, including securitization transactions, and where companies have continuing exposure to the risks
related to transferred financial assets. It eliminates the concept of a “qualifying special-purpose entity,” changes
the requirements for derecognizing financial assets, and requires additional disclosures. SFAS No. 167 changes
how a company determines when an entity that is insufficiently capitalized or is not controlled through voting (or

41

similar rights) should be consolidated. Both SFAS No. 166 and SFAS No. 167 are effective for fiscal years
beginning after November 15, 2009. The Company is evaluating the impact SFAS No. 166 and SFAS No. 167
will have on our consolidated financial statements.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

The Company is exposed to market risk consisting of foreign currency rate fluctuations and changes in

interest rates.

The Company is exposed to foreign currency exchange rate fluctuations in its operating statement due to
transactions denominated primarily in Canadian Dollars, British Pounds and Euros. Although historically the
Company has elected not to enter into any hedging contracts, it continually evaluates its foreign currency
exchange rate risk and the different mechanisms for use in managing such risk. A hypothetical 10% change in the
value of the U.S. dollar in relation to the Company’s most significant foreign currency exposures would have had
an impact of approximately $27 million on fiscal 2009 net sales. This amount is not indicative of the hypothetical
net earnings impact due to the partially offsetting impact of the currency exchange movements on cost of sales
and operating expenses.

The Company’s earnings are also affected by fluctuations in short-term interest rates through the investment

of its cash balances, borrowings under LIBOR-based debt instruments and the practice of selling fixed rate
equipment finance contracts under agreements with both a commercial paper conduit and a group of banks that
provide for pricing based on variable interest rates.

As of April 25, 2009, the Company had a $75 million variable-rate term note outstanding and $22 million

drawn on a variable-rate revolving credit facility. The Company views its variable interest rate debt position on a
net basis that gives effect to the Company’s cash and short term investments balances.

When considering the exposure under the agreements whereby the Company sells equipment finance
contracts to both a commercial paper conduit and a group of banks, the Company has the ability to select pricing
based on interest rates ranging from 30 day LIBOR up to twelve month LIBOR. In addition, the portfolio of
installment contracts generally turns over in less than 48 months and the Company can adjust the rate it charges
on new customer contracts at any time. Therefore, in times where the interest rate markets are not rapidly
increasing or decreasing, the average interest rate in the portfolio generally moves with the interest rate markets
and thus would parallel the underlying interest rate movement of the pricing built into the sale agreements. In
calculating the gain on the contract sales, the Company uses an interest rate curve that approximates the maturity
period of the then-outstanding contracts. If increases in the interest rate markets occur, the average interest rate in
our contract portfolio may not increase at the same rate, resulting in a reduction of gain on the contracts sales as
compared to the gain that would be realized if the average interest rate in our portfolio were to increase at a more
similar rate to the interest rate markets.

The Company estimates that if interest rates had been 10% higher during the year, the annual impact would

have been to reduce earnings before income tax by approximately $4 million.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
Patterson Companies, Inc.

We have audited Patterson Companies, Inc.’s internal control over financial reporting as of April 25, 2009,
based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (the COSO criteria). Patterson Companies, Inc.’s management is
responsible for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting included in Management’s Annual Report on Internal
Control over Financial Reporting appearing in Item 9A, Controls and Procedures, of this Annual Report on Form
10-K. Our responsibility is to express an opinion on Patterson Companies, Inc.’s internal control over financial
reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether effective internal control over financial reporting was maintained in all material respects. Our
audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a
material weakness exists, testing and evaluating the design and operating effectiveness of internal control based
on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We
believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

In our opinion, Patterson Companies, Inc. maintained, in all material respects, effective internal control over

financial reporting as of April 25, 2009, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board

(United States), the consolidated balance sheets of Patterson Companies, Inc. and subsidiaries as of April 25,
2009, and April 26, 2008, and the related consolidated statements of income, changes in stockholders’ equity,
and cash flows for each of the three fiscal years in the period ended April 25, 2009, and our report dated June 23,
2009, expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
Patterson Companies, Inc.

We have audited the accompanying consolidated balance sheets of Patterson Companies, Inc. and

subsidiaries as of April 25, 2009, and April 26, 2008, and the related consolidated statements of income, changes
in stockholders’ equity, and cash flows for each of the three fiscal years in the period ended April 25, 2009. Our
audits also included the financial statement schedule listed in Item 15(a)(2). These financial statements and
schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on
these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by management, as well as evaluating
the overall financial statement presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the
consolidated financial position of Patterson Companies, Inc. and subsidiaries at April 25, 2009, and April 26,
2008, and the consolidated results of their operations and their cash flows for each of the three fiscal years in the
period ended April 25, 2009, in conformity with U.S. generally accepted accounting principles. Also, in our
opinion, the related financial statement schedule, when considered in relation to the basic financial statements
taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board

(United States), Patterson Companies, Inc.’s internal control over financial reporting as of April 25, 2009, based
on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission, and our report dated June 23, 2009, expressed an unqualified
opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
APRIL 25, 2009
(Dollars in thousands, except share and per share amounts)

1. Summary of Significant Accounting Policies

Description of Business

Patterson Companies, Inc., “Patterson” or “the Company”, is a value-added distributor serving the dental,

companion-pet veterinarian and rehabilitation supply markets. The Company has three reportable segments:
dental supply, veterinary supply and rehabilitation supply.

Basis of Presentation

The consolidated financial statements include the accounts of the Company’s wholly owned subsidiaries.
Significant inter-company transactions and balances have been eliminated in consolidation. The respective assets
of PDC Funding Company, LLC and PDC Funding Company II, LLC, would be available first and foremost to
satisfy the claims of their respective creditors. There are no known creditors of PDC Funding Company, LLC or
PDC Funding Company II, LLC.

Fiscal Year End

The Company utilizes a fifty-two, fifty-three week fiscal year ending on the last Saturday in April.

Accordingly, fiscal years 2009, 2008 and 2007 included fifty-two weeks.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with U.S. generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities
and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash equivalents consist primarily of investments in money market funds, highly-rated commercial paper
and government securities. The maturity of these securities at the time of purchase is 90 days or less. All cash
equivalents are classified as available-for-sale and carried at fair value, which approximates cost.

Inventory

Inventory consists of merchandise held for sale and is stated at the lower of cost or market. Cost is
determined using the last-in, first-out (LIFO) method for all inventories, except for foreign inventories and
manufactured inventories, which are valued using the first-in, first-out (FIFO) method. Inventories valued at
LIFO represent 86% of total inventories at both April 25, 2009 and April 26, 2008, respectively.

The accumulated LIFO reserve was $51,934 at April 25, 2009 and $44,333 at April 26, 2008. The Company

believes that inventory replacement cost exceeds the inventory balance by an amount approximating the LIFO
reserve.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Property and Equipment

Property and equipment are stated at cost. The Company provides depreciation on the straight-line method
over estimated useful lives of up to 40 years for buildings or the expected remaining life of purchased buildings,
3 to 20 years for leasehold improvements or the term of the lease, if less, 5 years for data processing equipment,
and 5 to 10 years for office furniture and equipment.

Goodwill and Other Indefinite-Lived Intangible Assets

Goodwill represents the excess of cost over the fair value of identifiable net assets of businesses acquired.

Other indefinite-lived intangible assets include copyrights, trade names and trademarks.

The Financial Accounting Standards Board’s (“FASB”) Statement of Financial Accounting Standards
(“SFAS”) No. 142, “Goodwill and Other Intangible Assets” (“SFAS No. 142”), requires that goodwill for each
reporting unit be reviewed for impairment at least annually. The Company has three reporting units at April 25,
2009, which are the same as our operating units. The Company tests goodwill for impairment using the two-step
process prescribed in SFAS No. 142.

Fair value is determined using valuation techniques, including discounted cash flows and market multiple
analyses. These types of analyses contain uncertainties because they require management to make assumptions
and to apply judgment to estimate industry economic factors and the profitability of future business strategies.
The Company conducts impairment testing based on our current business strategy in light of present industry and
economic conditions, as well as future expectations.

In the fourth quarter of fiscal 2009, management completed its annual goodwill and other indefinite-lived

intangible asset impairment tests and determined there was no impairment. Although the Company believes our
estimates and assumptions used in estimating cash flows and determining fair value are reasonable, making
material changes to such estimates and assumptions could materially affect such impairment analyses and our
financial results, including an impairment charge that could be material.

Long-Lived Assets

Long-lived assets, including definite-lived intangible assets, are evaluated for impairment whenever events

or changes in circumstances indicate that the carrying amount of the assets may not be recoverable through the
estimated undiscounted future cash flows derived from such assets. The Company’s definite-lived intangible
assets primarily consist of an exclusive distribution agreement and customer lists. When impairment exists, the
related assets are written down to fair value.

Financial Instruments

The Company accounts for derivative financial instruments pursuant to SFAS No. 133, “Accounting for
Derivatives and Hedging Activities,” and SFAS No. 138, “Accounting for Certain Derivative Instruments and
Certain Hedging Activity, an Amendment of SFAS No. 133.” SFAS No. 133 and No. 138 require that all
derivative financial instruments be recorded on the balance sheet at their respective fair value.

The Company’s use of derivative financial instruments is generally limited to managing well-defined
interest rate risks. The Company does not use financial instruments or derivatives for any trading purposes.

Revenue Recognition

Revenues recognized include product sales, billings for freight and delivery charges, and fees earned for

services provided. Consumable and printed product sales and billings for freight and delivery charges are

51

PATTERSON COMPANIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

recorded upon delivery, except in those circumstances where terms of the sale are FOB shipping point.
Equipment and software product revenues are also recognized upon delivery. Revenues for these products are
recorded upon delivery since at that time risk of loss has transferred to the customer, there is persuasive evidence
that an arrangement exists, the price is fixed and final, and there is reasonable assurance of collection of the sales.
In those circumstances where terms of the sale are FOB shipping point, revenues are recognized when products
are transferred to the shipping carrier. Estimates for returns, damaged goods, rebates and other revenue
allowances are made at the time of sale based on the historical experience for such items. Revenue derived from
post contract customer support for software is deferred and recognized ratably over the period in which the
support is provided. Other service revenues are recorded on the date services are completed.

The receivables that result from the recognition of revenue by the Company are reported net of the related

allowances discussed above. The Company also maintains a valuation allowance based upon the expected
collectibility of receivables held. Estimates are used to determine the valuation allowance and are based on
several factors, including historical collection data, economic trends and credit worthiness of customers.
Receivables are written off when the Company determines the amounts to be uncollectible, typically upon
customer bankruptcy or non-response to continuous collection efforts. See also Note 6, “Customer Financing”.
The portions of receivable amounts that are not expected to be collected during the next twelve months are
classified as long-term.

The Company has a relatively large and disperse customer base and no single customer accounts for more

than 1% of consolidated net sales. In addition, the equipment sold to customers under finance contracts generally
serves as collateral for the contract and the customer provides a personal guarantee as well.

Freight and Delivery Charges

Freight and delivery charges incurred by the Company are included in cost of sales.

Advertising

The Company expenses all advertising and promotional costs as incurred, except for direct marketing

expenses, which are expensed over the shorter of the life of the asset or one year. Total advertising and
promotional expenses were $22,105, $22,665 and $21,775 for fiscal years 2009, 2008 and 2007, respectively.
Deferred direct-marketing expenses included in prepaid and other current assets on the consolidated balance
sheet as of April 25, 2009 and April 26, 2008 were $3,512 and $3,490, respectively.

Income Taxes

The liability method is used to account for income tax expense. Under this method, deferred tax assets and
liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to
reverse.

Employee Stock Ownership Plan (ESOP)

Compensation expense related to the Company’s defined contribution ESOP is computed based on the

shares allocated method.

Share-Based Compensation

The Company recognizes share-based compensation expense based on the grant-date fair value of awards

estimated in accordance with FASB Statement No. 123(R), “Share-based Payment”.

52

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Comprehensive Income

Comprehensive income is computed as net income plus certain other items that are recorded directly to
stockholders’ equity. The only significant item included in comprehensive income is foreign currency translation
adjustments. Foreign currency translation adjustments do not include a provision for income tax because earnings
from foreign operations are considered to be indefinitely reinvested outside the U.S.

Earnings Per Share

The amount of basic earnings per share is computed by dividing net income by the weighted average
number of outstanding common shares during the period. The amount of diluted earnings per share is computed
by dividing net income by the weighted average number of outstanding common shares and common share
equivalents, when dilutive, during the period.

The following table sets forth the denominator for the computation of basic and diluted earnings per share.

There were no material adjustments to the numerator.

Options to purchase 1,143, 568 and 764 shares of common stock during fiscal years 2009, 2008 and 2007,
respectively, were excluded from the calculation of diluted earnings per share because the effect would have been
anti-dilutive. Unvested restricted stock awards outstanding which were excluded from the calculation of diluted
earnings per share during fiscal years 2009, 2008 and 2007 were 270, 1, and 76, respectively, because the effect
would have been anti-dilutive.

Recent Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial
Accounting Standards (“SFAS”) No. 157, “Fair Value Measurements” (“SFAS No. 157”), which defines fair
value, provides a framework for measuring fair value, and expands the disclosures required for assets and
liabilities measured at fair value. SFAS No. 157 applies to existing accounting pronouncements that require fair
value measurements, but it does not require any new fair value measurements. In February 2008, the FASB
issued Staff Position FAS 157-2, which deferred the effective date of SFAS No. 157 as it relates to nonfinancial
assets and liabilities. The Company adopted the disclosure requirements of the effective portions of SFAS No.
157 at the beginning of fiscal 2009. The Company is evaluating the impact of the remaining portions of SFAS
No. 157, which are effective at the beginning of our fiscal year 2010.

In February 2007, the FASB issued Statement No. 159, “The Fair Value Option for Financial Assets and
Financial Liabilities” (“SFAS 159”), which permits entities to choose to measure many financial instruments and
certain other items at fair value. The Company adopted SFAS No. 159 beginning the first quarter of fiscal 2009,
but did not elect the fair value option for any of its financial assets or liabilities.

53

PATTERSON COMPANIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In March 2008, the FASB issued Statement No. 161, “Disclosures about Derivative Instruments and

Hedging Activities, an amendment of FASB Statement No. 133” (“SFAS No. 161”). SFAS No. 161 requires
enhanced disclosures about derivatives and hedging activities and was adopted in the fourth quarter of fiscal
2009. Since SFAS No. 161 requires only additional disclosures concerning derivatives and hedging activities, the
adoption of SFAS No. 161 did not have a material impact on our consolidated financial statements.

In December 2007, FASB issued Statement No. 141(revised 2007), “Business Combinations” (“SFAS
No. 141(R)”). SFAS No. 141(R) significantly changes the accounting for business combinations in a number of
areas including the treatment of contingent consideration, preacquisition contingencies, transaction costs,
in-process research and development and restructuring costs. In addition, under SFAS No. 141(R), changes in an
acquired entity’s deferred tax assets and uncertain tax positions after the measurement period will impact income
tax expense. SFAS No. 141(R) is effective for fiscal years beginning after December 15, 2008 and will change
our accounting treatment for business combinations on a prospective basis.

In June 2009, the FASB issued Statement No. 166, “Accounting for Transfers of Financial Assets-an

Amendment of FASB Statement No. 140” (“SFAS No. 166”) and Statement No. 167, “Amendments to FASB
Interpretation No. 46(R)” (“SFAS No. 167”). SFAS No. 166 will require more information about transfers of
financial assets, including securitization transactions, and where companies have continuing exposure to the risks
related to transferred financial assets. It eliminates the concept of a “qualifying special-purpose entity,” changes
the requirements for derecognizing financial assets, and requires additional disclosures. SFAS No. 167 changes
how a company determines when an entity that is insufficiently capitalized or is not controlled through voting (or
similar rights) should be consolidated. Both SFAS No. 166 and SFAS No. 167 are effective for fiscal years
beginning after November 15, 2009. The Company is evaluating the impact SFAS No. 166 and SFAS No. 167
will have on our consolidated financial statements.

Related to fiscal 2009 acquisitions, the Company has recorded approximately $28.8 million of amortized
intangible assets with an average life of 8.1 years. In 2006, the Company extended its exclusive North American
distribution agreement with Sirona Dental Systems GmbH (“Sirona”) for Sirona’s CEREC 3D dental restorative
system. The Company paid a $100 million distribution fee to extend the agreement for a 10-year period that
began in October 2007. The distribution fee is included in identifiable intangibles, net in the consolidated balance
sheet. The amortization of the distribution agreement fee is recorded over the 10-year period based on estimates
of the pattern in which the economic benefits of the fee are expected to be realized, consisting primarily of
revenues generated from the sale of CEREC 3D dental restorative systems. Amortization expense in any year
may differ significantly from other years.

With respect to the amortized intangible assets, future amortization expense is expected to approximate
$14,200, $14,900, $15,000, $15,700 and $17,200 for fiscal years 2010, 2011, 2012, 2013 and 2014, respectively.
The preceding expected amortization expense is an estimate. Actual amounts of amortization expense may differ
from estimated amounts due to additional intangible asset acquisitions, finalization of preliminary valuations,
actual revenues generated from the sale of CEREC 3D dental restorative systems, changes in foreign currency
exchange rates, impairment of intangible assets, accelerated amortization of intangible assets and other events.

4. Acquisitions

On December 19, 2008, the Company completed the acquisition of Dolphin Imaging Systems, LLC and

Dolphin Practice Management, LLC (together, “Dolphin”), leading providers of 3D imaging and practice
management software for specialized dental practitioners, including orthodontists, oral maxillofacial surgeons
and dental radiologists. As of April 25, 2009, initial goodwill of approximately $22.3 was recorded related to this
acquisition.

On October 2, 2008, the Company completed the acquisition of the Columbus Serum Company

(“Columbus”), a full service distributor of companion-pet veterinary supplies, equipment and pharmaceuticals.
As of April 25, 2009, initial goodwill of approximately $25.0 million was recorded related to this acquisition.

The combined purchase price of Dolphin and Columbus totaled approximately $95.5 million. In addition to

the acquisitions of Dolphin and Columbus, we completed other acquisitions during fiscal years 2009, 2008 and
2007. The operating results of each of these acquisitions are included in the Company’s consolidated statements
of income from the date of each acquisition. Pro forma results of operations and details of the purchase price
allocations have not been presented for these acquisitions since the effects of these business acquisitions were not
material to the Company either individually or in the aggregate. A listing of acquisitions completed during the
periods covered by these financial statements is presented below:

Construction-in-progress as of April 25, 2009 was related primarily to a distribution facility project in
Florida. The Company is contractually committed to approximately $6 million of additional expenditures related
to this project. Construction-in-progress as of April 26, 2008 was comprised mostly of a project to expand an
existing distribution facility in California and the expansion of the Company’s corporate headquarters. These
projects were completed in fiscal 2009.

6. Customer Financing

As a convenience to its customers, the Company offers several different financing alternatives including
both a Company sponsored program and a third party program. For the third party program, the Company acts as
a facilitator between the customer and the third party financing entity with no on-going involvement in the
financing transaction. Under the Company sponsored program, equipment purchases by customers with strong
credit are financed to a maximum of $0.4 million for any one customer. The Company generally sells the
customers’ financing contracts to outside financial institutions in the normal course of its business. The Company
currently has two arrangements under which it sells these contracts.

In fiscal 2003, the Company initiated an agreement to sell its equipment finance contracts to a commercial

paper conduit managed by JPMorgan Chase Bank N.A. To participate in the commercial paper conduit, the
Company was required to establish a special purpose entity (“SPE”), PDC Funding Company, LLC, a
consolidated, wholly owned subsidiary. The Company transfers financing contracts to the SPE and in turn, the
SPE sells the contracts to the commercial paper conduit. The SPE does not issue any debt. While there is no
recourse to the Company by the commercial paper conduit on the sale of contracts, the Company receives only
90% of the principal amount of the contracts upon the sale. The remaining 10% of the proceeds is held by the
conduit as security against the eventual performance of the portfolio. The holdback receivable from the conduit is
recorded as a non-current asset, which is carried at its estimated fair market value. The capacity of this
arrangement with the conduit is a maximum of $367 million.

The Company also maintains an agreement with U.S. Bank National Association, as agent, whereby the
U.S. Bank group purchases customers’ financing contracts. The Company has established another SPE, PDC
Funding LLC II (“PDC II”), as a consolidated, wholly owned subsidiary, which sells financing contracts to the
U.S. Bank group. The Company receives 94% of the principal amounts of the contracts upon sale with the
remaining 6% of the proceeds held by the banks as security against the eventual performance of the portfolio.
The holdback receivable from the banks is recorded as a non-current asset, which is carried at its estimated fair
market value. The capacity under the agreement is $110 million.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

These financing arrangements are accounted for as a sale of assets under the provisions of SFAS No. 140,
“Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities.” During fiscal
2009, 2008 and 2007, the Company sold approximately $189.5, $229.7 and $247.0 million, respectively, of its
contracts under these arrangements. The Company retains servicing responsibilities under both agreements, for
which it is paid a servicing fee. The servicing fees received by the Company are considered adequate
compensation for services rendered. Accordingly, no servicing asset or liability has been recorded. The
agreements require the Company to maintain a minimum current ratio and maximum leverage ratio. The
Company was in compliance with the covenants at April 25, 2009.

Included in current receivables in the consolidated balance sheets are approximately $136.1 million and

$48.2 million as of April 25, 2009 and April 26, 2008, respectively, of finance contracts not yet sold by the
Company. A total of $372.6 million of finance contracts receivable sold under the agreements were outstanding
at April 25, 2009. The residual receivable under the arrangements was approximately $45.1 and $47.7 million as
of April 25, 2009 and April 26, 2008, respectively. Since the internal financing program began in 1994, bad debt
write-offs have amounted to less than one-percent of the loans originated.

7. Long-Term Debt

In March 2008, the Company issued fixed-rate senior notes with an aggregate principal amount of $450

million, consisting of (i) $50 million 4.63% senior notes, due fiscal 2013; (ii) $250 million 5.17% senior notes,
due fiscal 2015; and (iii) $150 million 5.75% senior notes, due fiscal 2018.

Also in March 2008, the Company entered into a term loan agreement with a principal amount of $75
million, which matures in fiscal 2013. The term loan bears interest at a floating rate based on LIBOR plus a
spread which can range from 0.50% to 1.25% based on our leverage ratio, as defined in the agreement. During
the year ended April 25, 2009, the weighted average interest rate of this term loan was 3.44%.

The proceeds from the issuance of debt in March 2008 were used to repurchase shares of the Company’s
common stock and to repay borrowings under the Company’s revolving line of credit. The remaining proceeds
were used for general corporate purposes. Debt issuance costs associated with the issuance of debt in March 2008
of $1.8 million are being amortized to interest expense over the life of the related debt.

In addition, in March 2008 the Company entered into two forward starting interest rate swap agreements,

each with notional amounts of $100 million and accounted for as cash flow hedges, to hedge interest rate
fluctuations in anticipation of the issuance of the 5.17% senior notes due fiscal 2015 and the 5.75% senior notes
due fiscal 2018, respectively. Upon issuance of the hedged debt, the Company settled the forward starting interest
rate swap agreements and recorded a $1.0 million increase, net of income taxes, to accumulated other
comprehensive income, which is being amortized against interest expense over the life of the related debt. The
pre-tax amount reclassified into earnings during fiscal 2009 was $0.2 million. The amount expected to be
reclassified into earnings during fiscal 2010 is also expected to be $0.2 million.

The Company has available a $300 million revolving credit facility through November 2012. Interest on
borrowings is based on LIBOR plus a spread which can range from 0.40% to 1.00%. This spread as well as a
commitment fee on the unused portion of the facility are based on our leverage ratio, as defined in the agreement.
Outstanding borrowings under the facility at April 25, 2009 and April 26, 2008 were $22 million and $0,
respectively. The interest rate on the outstanding borrowings under this facility was 3.25% as of April 25, 2009.

The debt agreements contain various financial covenants including certain leverage and interest coverage
ratios as defined in the Company’s debt agreements. The Company met the financial covenants under the debt
agreements as of April 25, 2009. The estimated fair value of our debt as of April 25, 2009 and April 26, 2008
was at $514.3 million and $635.4 million, respectively.

8. Derivative Financial Instruments

The Company is a party to certain offsetting and identical interest rate cap agreements. These cap

agreements were entered into to fulfill certain covenants of a sale agreement between a commercial paper conduit
managed by JPMorgan Chase Bank, N.A. and PDC Funding. The cap agreements provide a credit enhancement
feature for the financing contracts sold by PDC Funding to the commercial paper conduit, and replace a
minimum interest rate margin previously required under the sale agreement.

The cap agreements are cancelled and new agreements entered into periodically to maintain consistency
with the dollar maximum of the sale agreements and the maturity of the underlying financing contracts. PDC
Funding has purchased two interest rate caps from banks with combined amortizing notional amounts of $367
million and a maturity date of March 2014. Patterson Companies, Inc. sold two identical interest rate caps to the
same banks. Similar to the above agreements, PDC Funding II and Patterson Companies, Inc. entered into
offsetting and identical interest rate swap agreements in fiscal 2008. These agreements have an amortizing
notional of $110 million and a maturity date of September 2013.

PATTERSON COMPANIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In addition to the identical purchased and sold interest rate contracts described above, the Company has
entered into two interest rate swap agreements with banks to economically hedge the interest rate risk associated
with our finance contracts. As of April 25, 2009, the agreements have notional amounts of approximately $30
million and $42 million, respectively, and maturity dates of November 2011 and February 2012, respectively.

None of the Company’s interest rate contracts qualify for hedge accounting treatment and, accordingly, the
Company records the fair value of the agreements as an asset or liability and the change in any period as income
or expense of the period in which the change occurs.

9. Fair Value Measurements

As discussed in Note 1, the Company adopted the disclosure requirements of the effective portions of
SFAS No. 157 at the beginning of fiscal 2009. The Company is evaluating the impact of the remaining portions
of SFAS No. 157, which are effective at the beginning of our fiscal year 2010. SFAS No. 157 establishes the
following hierarchy which prioritizes the inputs used to measure fair value from market based assumptions to
entity specific assumptions as follows:

Level 1 – Quoted prices in active markets for identical assets and liabilities at the measurement date.

Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for

similar assets and liabilities in active markets; quoted prices for identical or similar assets and
liabilities in markets that are not active; or other inputs that are observable or can be
corroborated by observable market data.

Level 3 – Unobservable inputs for which there is little or no market data available. These inputs reflect

management’s assumptions of what market participants would use in pricing the asset or
liability.

The Company adopted FIN 48 and FSP FIN 48-1 effective April 29, 2007, the first day of fiscal 2008, with
no adjustment to the opening balance of retained earnings. These standards clarify the separate identification and
reporting of estimated amounts that could be assessed upon audit. The potential assessments are considered
unrecognized tax benefits, because, if it is ultimately determined they are unnecessary, the reversal of these
previously recorded amounts will result in a beneficial impact to the Company’s financial statements.

As of April 25, 2009 and April 26, 2008, the Company’s gross unrecognized tax benefits were $17.5 million
and $19.6 million, respectively. If determined to be unnecessary, these amounts (net of deferred tax assets of $5.2
million and $5.7 million, respectively, related to the tax deductibility of the gross liabilities) would decrease our
effective tax rate. The gross unrecognized tax benefits are included in other long-term liabilities on the
consolidated balance sheet.

A summary of the changes in the gross amounts of unrecognized tax benefits for the year ended April 25,

2009 is shown below:

The Company also recognizes both interest and penalties with respect to unrecognized tax benefits as a
component of income tax expense. As of April 25, 2009 and April 26, 2008, the Company had recorded $3.2
million and $3.1 million, respectively, for interest and penalties. These amounts are also included in other long-
term liabilities on the consolidated balance sheet. These amounts, net of related deferred tax assets, if determined
to be unnecessary, would decrease the Company’s effective tax rate. During the year ended April 25, 2009, the
Company recorded as part of tax expense $1.3 million related to an increase in its estimated liability for interest
and penalties.

The Company files income tax returns, including returns for our subsidiaries, with federal, state, local and

foreign jurisdictions. The Company is not currently under audit by the Internal Revenue Service (“IRS”). The
IRS has either examined or waived examination of all periods up to and including our fiscal year ended April 30,
2005. Periodically, state, local and foreign income tax returns are examined by various taxing authorities. The
Company does not believe the outcome of these various examinations would have a material adverse impact on
our financial statements.

13. Stockholders’ Equity

Share Repurchases

During fiscal 2008, the Company repurchased 11.7 million shares of its common stock on the open market
at a total cost of $386.1 million. On March 19, 2008, the Company entered into an accelerated share repurchase
agreement (“ASR”) with financial institution counterparty. Under the terms of the ASR, the Company paid $250
million and took delivery of 90% of the shares, or 6.3 million shares, based on an initial share price of $35.60.
The final number of shares to be delivered by the counterparty under the ASR was dependent on prevailing
market conditions and based on the difference between the initial purchase price per share and a volume
weighted average price of the Company’s common stock, minus a set discount, during a period of up to six
months. Under terms of the ASR, the Company could have received additional shares of common stock from the
counterparty or could have been required to deliver shares or cash to the counterparty. On June 18, 2008, the
transaction was settled and an additional 1,052,037 shares were delivered to the Company, bringing the total
number of shares delivered under the ASR to 7,372,260 at an average price of $33.91.

Employee Stock Ownership Plan (ESOP)

During 1990, the Company’s Board of Directors adopted a leveraged ESOP. During fiscal 1991, under the

provisions of the plan and related financing arrangements, the Company loaned the ESOP $22,000 (the “1990
note”) for the purpose of acquiring its then outstanding preferred stock which was subsequently converted to
common stock. At April 25, 2009 and April 26, 2008, indebtedness of the ESOP to the Company is shown as a
deduction from stockholders’ equity in the consolidated balance sheets. The cost of the ESOP is borne by the
Company through annual contributions to the plan in amounts determined by the Board of Directors. Shares of
stock acquired by the plan are allocated to each participant who has completed 1,000 hours of service during the
plan year.

The Company’s ESOP and an ESOP sponsored by the Thompson Dental Company (“Thompson”) were
used to facilitate the acquisition and merger of Thompson into the Company. The net result of this transaction
was an additional loan of $12,612 being made to the ESOP and the ESOP acquiring 665,978 shares of common
stock of the Company. Under current accounting standards, these shares are not considered outstanding for the
computation of earnings per share until the shares are allocated to the participants. When the shares are allocated
to the participants, the expense to the Company will be determined based on the fair market value of the shares in
the year of the allocation. The loan bears interest at current rates but principal does not begin to amortize until
2011. A total of 665,978 shares were issued in the transaction of which 97,810 were previously allocated to
Thompson employees. The remaining 568,168 shares began to be allocated in fiscal 2004 but only to the extent
of interest on the loan. The non-cash expense is not expected to materially impact the consolidated results of
operations of the Company until principal becomes due.

During fiscal 2009, 2008 and 2007, shares secured by the 1990 note with a cost of $1,500, $1,200 and

$1,202, respectively, were earned and allocated to ESOP participants.

At April 25, 2009, a total of 11,749,806 shares of the common stock were allocated to participants and had a

fair market value of $233,821. With respect to the 1990 note, shares allocated were 14,152,087,
committed-to-be-released shares were 1,578,601 and suspense shares were 3,420,911. Related to the shares from
the Thompson transaction, shares allocated were 164,024, committed-to-be-released shares were 11,808 and
suspense shares were 490,146.

On September 11, 2006, the Company entered into a third loan agreement with the ESOP and loaned $105

million (the “2006 note”) for the sole purpose of enabling the ESOP to purchase shares of the Company’s
common stock (the “Securities”) in the open market and pay any corresponding broker commissions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The 2006 note is payable in full on September 10, 2026. Interest on the unpaid principal balance accrues at a

rate equal to six-month LIBOR, with the rate resetting semi-annually. Interest payments are not required during
the period from and including September 11, 2006 through April 30, 2010. On April 30, 2010, any accrued and
unpaid interest will be added to the outstanding principal balance under the note, with interest thereafter accruing
on the increased principal amount. Unpaid interest accruing after April 30, 2010 is due and payable on April 30,
2011 and each successive April 30 occurring through September 10, 2026.

The ESOP purchased 3,159,645 shares with the proceeds from the 2006 note. This loan and related shares,

as well as the Thompson shares, are being accounted for under SOP 93-6, “Employers’ Accounting for Stock
Ownership Plans” and accordingly, unallocated shares held by the Trust are not considered outstanding in the
computation of earnings per share. The Company anticipates the allocation of the shares related to the 2006 note
to begin in fiscal 2012 over a period of approximately 10 to 15 years. As of April 25, 2009, the fair value of
unreleased shares accounted for under SOP 93-6 was approximately $72.6 million.

14. Share-based Compensation

Effective April 30, 2006, the Company adopted SFAS No. 123(R), “Share-Based Payment” (“SFAS
No. 123(R)”) using the modified prospective method in which compensation cost is recognized beginning with
the effective date (a) based on the requirements of SFAS No. 123(R) for all share-based awards granted after the
effective date and (b) based on the requirements of SFAS 123 for all awards granted to employees prior to the
effective date of SFAS No. 123(R) that remain unvested on the effective date.

The consolidated statements of income for fiscal years 2009, 2008 and 2007 include pre-tax share-based
compensation expense of $7.7 million ($5.6 after-tax), $7.7 million ($6.1 after-tax) and $7.8 million ($6.3 after-tax),
respectively, all of which is included in operating expenses within the consolidated statements of income. The
consolidated statement of cash flows present the pre-tax share-based compensation expense as an adjustment to
reconcile net income to net cash provided by operating activities. In addition, benefits associated with tax
deductions in excess of recognized compensation expense are presented as a cash inflow from financing activities.
For fiscal years 2009, 2008 and 2007, these excess benefits totaled $0.3, $0.8 and $0.7 million, respectively.

As of April 25, 2009, the total compensation cost, before income taxes, related to non-vested awards yet to

be recognized was $15.9 million, and it is expected to be recognized over a weighted average period of
approximately 4.4 years.

Description of General Methods and Assumptions Used to Estimate Fair Value

Described below are certain methods and assumptions used to estimate the fair value of share-based

compensation awards. Further information is presented below within this Note that may be unique to a particular
award or group of awards.

Expected dividend yield – the Company has not and does not currently expect to pay dividends.
Accordingly, the expected dividend yield used is 0%.

Expected stock price volatility – the Company considers historical volatility trends, implied future volatility
based on certain traded options of the Company, and other factors.

Risk-free interest rate – the Company bases the risk-free interest rate on the U.S. Treasury yield curve in
effect at the grant date with similar terms to the expected term of the award.

Expected term of stock options and restricted stock – The Company estimates the expected term, or life, of
awards based on several factors, including grantee types, vesting schedules, contractual terms and various
factors surrounding exercise behavior of different groups.

Director and Employee Stock Option Plans

In June 1992, the Company adopted a Director Stock Option Plan. Options were granted at the fair market

value of the underlying stock on the date of grant, vest over one year, and are exercisable for a period of four
years commencing one year after the date of grant. This plan terminated during fiscal 2002.

In September 2001, the Company adopted a new Director Stock Option Plan. A total of 800,000 shares of
common stock have been reserved for issuance under this plan. Options are granted at fair market value of the
underlying stock on the option grant date, vest over one year, and are exercisable for a period of nine years
commencing one year after the grant date. In addition, each eligible director will have the right to elect to receive
additional options in lieu of the amount of the director’s annual fee for service on the board of directors.

In June 1992, the Company adopted the Patterson Dental Company 1992 Stock Option Plan, a plan for
employees. Due to the expiration of this plan in fiscal 2003, no options remain available for future issuance under
this plan. In September 2002, the Company adopted a new employee equity award plan. A total of 6,000,000
shares of common stock were reserved for issuance under the plan. In September 2004, the Company’s
shareholders voted to approve the Amended and Restated 2002 Stock Option Plan, a restatement of the 2002
plan. Upon approval, the Plan was renamed the “Patterson Companies, Inc. Equity Incentive Plan” (“Equity
Incentive Plan”).

The Equity Incentive Plan amendments did not change the number of shares reserved for awards under the

plan. The Equity Incentive Plan authorizes various award types to be issued under the plan, including stock
options, restricted stock and restricted stock units, stock bonuses, cash bonuses, stock appreciation rights,
performance awards and dividend equivalents. Awards may have a term no longer than ten years and vesting
terms are determined by the compensation committee of the board of directors. The minimum restriction period
for restricted stock and restricted stock units is three years, or one year in the case of performance-based awards.
Additionally, the maximum number of shares that may be issued pursuant to awards of restricted stock, restricted
stock awards and stock bonuses is 2,000,000 shares. Prior to fiscal 2006, only stock option awards had been
granted under the Equity Incentive Plan. During fiscal years 2009, 2008 and 2007, expense recognized related to
stock options was $2.0 million, $2.4 million and $2.9 million, respectively.

The fair value of stock options granted was estimated as of the grant date using a Black-Scholes option-

pricing model with the following weighted average assumptions during fiscal years 2009, 2008 and 2007:

(a) Weighted-average exercise price

The weighted average fair values of options granted during fiscal years 2009, 2008 and 2007 were $13.50,
$15.88 and $13.44, respectively. The weighted average remaining contractual lives of options outstanding and
options exercisable as of April 25, 2009 were 4.0 and 3.9 years, respectively. The Company settles stock option
exercises with newly issued common shares.

Related to stock options exercised, the intrinsic value, cash received and tax benefits realized were $2.5,
$1.6 and $0.8 million, respectively, in fiscal 2009; $4.7, $3.2 and $1.2 million, respectively, in fiscal 2008; and,
$4.7 million, $4.5 million and $1.3 million, respectively, in fiscal 2007.

Restricted Stock and Performance Unit Awards

Beginning in fiscal 2006, the Company issued restricted stock and performance unit awards under the
Equity Incentive Plan. The grant date fair value is based on the closing stock price on the day of the grant.
Restricted stock awards to employees vest over a seven or nine-year period and are subject to forfeiture
provisions. Certain restricted stock awards, which are held by line management, are subject to accelerated vesting
provisions beginning three years after the grant date, based on certain operating goals. Restricted stock awards
are also granted to non-employees directors on the date of each annual board meeting. These awards vest over
three years. The performance unit awards, issued primarily to executive management, are earned at the end of a
three-year period if certain operating goals are met, and are settled in an equivalent number of common shares or
in cash as determined by the compensation committee of the board of directors. The satisfaction of operating
goals will not be finally determined until the end of a three-year period. Accordingly, the Company recognizes
expense related to performance unit awards over the requisite service period using the straight-line method based
on the outcome that is probable. During fiscal years 2009, 2008 and 2007, expense recognized related to

Employee Stock Purchase Plan

In June 1992, Company adopted an Employee Stock Purchase Plan (the “Stock Purchase Plan”). A total of
4,750,000 shares of common stock are reserved for issuance under the Stock Purchase Plan. The Stock Purchase
Plan, which is intended to qualify under Section 423 of the Internal Revenue Code, is administered by the Board
of Directors of the Company or by a committee appointed by the Board of Directors and follows a calendar plan
year. Employees are eligible to participate after nine months of employment with the Company if they are
employed for at least 20 hours per week and more than five months per year. The Stock Purchase Plan permits
eligible employees to purchase common stock through payroll deductions, which may not exceed 10 percent of
an employee’s compensation, at 85 percent of the lower of the fair market value of the common stock on the

offering date or at the end of each three-month period following the offering date during the applicable offering
period. Employees may end their participation in the offering at any time during the offering period, and
participation ends automatically on termination of employment with the Company. At April 25, 2009, there were
1,241,788 shares available for purchase under the Stock Purchase Plan.

Based on the provisions of the Stock Purchase Plan and guidance provided in FASB Technical Bulletin
No. 97-1, “Accounting Under Statement 123 for Certain Employee Stock Purchase Plans with a Look-back
Option” (“FTB 97-1”), there are several option elements for which the fair value is estimated on the grant date
using the Black-Scholes option-pricing model. Total expense recognized related to the employee stock purchase
plan was $1.6, $1.9 and $2.1 million during fiscal years 2009, 2008 and 2007, respectively. The following table
summarizes the weighted-average assumptions relating to the Stock Purchase Plan for fiscal years 2009, 2008
and 2007:

Capital Accumulation Plan

In 1996, the Company adopted an employee Capital Accumulation Plan (the “CAP Plan”). A total of

6,000,000 shares of common stock are reserved for issuance under the CAP Plan. Key employees of the
Company or its subsidiaries are eligible to participate by purchasing common stock through payroll deductions,
which must be between 5% and 25% of an employee’s compensation, at 75% of the price of the common stock at
the beginning of or the end of the calendar year, whichever is lower. The shares issued are restricted stock and
are held in the custody of the Company until the restrictions lapse. The restriction period is three years from the
beginning of the plan year, but restricted shares are subject to forfeiture provisions. At April 25, 2009, 2,632,389
shares were available for purchase under the CAP Plan.

Based on the provisions of the CAP Plan and guidance provided in FTB No. 97-1, there are option elements

for which the fair value is estimated on the grant date using the Black-Scholes option-pricing model. Total
expense recognized related to the Cap Plan was $1.6, $1.8 and $1.9 million during fiscal years 2009, 2008 and
2007, respectively. The following table summarizes the weighted-average assumptions relating to the CAP Plan
for fiscal years 2009, 2008 and 2007:

15. Litigation

The Company is involved in various product related, employment related and other legal proceedings
arising in the ordinary course of business. Some of these proceedings involve product liability claims arising out
of the use of products the Company distributes. Product liability indemnification is generally obtained from our
suppliers. However, in the event a supplier of a defective product is unable to pay a judgment for which the
Company may be jointly liable, the Company would have liability for the entire judgment.

71

PATTERSON COMPANIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The Company maintains product liability insurance coverage for any potential liability for claims arising out

of products sold by the Company. While the Company believes its insurance coverage is adequate, there can be
no assurance that our insurance coverage is sufficient or will be available to us in adequate amounts or at
reasonable costs in the future. Also, there can be no assurance that the indemnification agreements with our
suppliers will provide us with adequate protection. In addition, future claims brought against the Company could
involve claims not covered by insurance or indemnification agreements, and could have a material adverse effect
on the Company’s business or financial condition.

As of April 25, 2009 and April 26, 2008, the Company had accrued our best estimate of potential losses

relating to product liability and other claims that were probable to result in a liability and for which it was
possible to reasonably estimate a loss. These accrued amounts, as well as related expenses, have not been
material to our financial position, results of operations or cash flows. Our method for determining estimated
losses considers currently available facts, presently enacted laws and regulations and other external factors,
including probable recoveries from third parties.

16. Quarterly Results (unaudited)

Quarterly results are determined in accordance with the accounting policies used for annual data and include

certain items based upon estimates for the entire year. All fiscal quarters include results for 13 weeks. The

Item 9A. CONTROLS AND PROCEDURES

Management’s Annual Report on Internal Control Over Financial Reporting

The management of Patterson Companies, Inc. (the “Company”) is responsible for establishing and

maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under
the Securities Exchange Act of 1934. The Company’s internal control system is designed to provide reasonable
assurance to our management and Board of Directors regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with generally accepted accounting
principles. The Company’s internal control over financial reporting includes those policies and procedures that:

Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions

and dispositions of the assets of the Company;

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial

statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the
Company are being made only in accordance with authorizations of management and directors of the Company;
and

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or

disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Therefore, even those internal control systems determined to be effective can provide only
reasonable assurance with respect to financial statement preparation and presentation.

Under the supervision and with the participation of our management, including our principal executive
officer and principal financial and accounting officer, we assessed the effectiveness of our internal control over
financial reporting as of April 25, 2009, using the criteria set forth by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework. Based on its
assessment, management has concluded that our internal control over financial reporting was effective as of
April 25, 2009. During its assessment, management did not identify any material weaknesses in our internal
control over financial reporting. Ernst & Young LLP, the independent registered public accounting firm that
audited our consolidated financial statements included in Item 8, Financial Statements and Supplementary Data,
of this Annual Report on Form 10-K, has issued an unqualified report on our internal control over financial
reporting.

Evaluation of Disclosure Controls and Procedures

As of April 25, 2009, the Company carried out an evaluation, under the supervision and with the

participation of the Company’s management, including the Company’s Chief Executive Officer and its Chief
Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and
procedures pursuant to Rules 13a-15 and 15d-15 of the Securities and Exchange Act of 1934 (the “Exchange
Act”). Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the
Company’s disclosure controls and procedures were effective. Disclosure controls and procedures are defined by
Rules 13a-15(e) and 15d-15(e) of the Exchange Act as controls and other procedures that are designed to ensure
that information required to be disclosed by the Company in reports filed with the SEC under the Exchange Act
is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that
information required to be disclosed by us in reports filed under the Exchange Act is accumulated and
communicated to our management, including our principal executive and principal financial officers, or person
performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

During the fourth quarter of fiscal year 2009, there were no significant changes in the Company’s internal
controls over financial reporting that have materially affected, or are reasonably likely to materially affect, the
Company’s internal controls over financial reporting.

PATTERSON COMPANIES, INC.
Fiscal 2010
Incentive Plan

Exhibit 10.6

PLAN PURPOSE

The objective of Fiscal 2010 Patterson Companies, Inc. (PDCO) Incentive Compensation Plan (the “Plan”)

is to encourage greater initiative, resourcefulness, teamwork, and efficiency on the part of its employees. The
day-to-day performance and responsibilities of each individual have a direct impact on our internal and external
customer satisfaction, sales and operational goals, which ultimately affects the profitability of the Company.

ELIGIBILITY

Participation

This Incentive Program is designed to include designated employees across the organization. Incentive
opportunity for targeted groups of employees is specified in the Plan schedules attached to this document. Newly
hired, transferred, or employees who become participants during the Plan year will be eligible on a prorated basis
under the respective schedule.

Participation in the Plan is determined by the CEO with approval of the President of each respective
subsidiary or operating unit and is based on level of responsibility and organizational impact of the participant.

Participants are eligible for participation in only one Patterson Companies, Inc. (or subsidiary thereof)
incentive, bonus, or other variable pay program, unless so authorized by specific provisions included in this Plan
and the respective Patterson Companies, Inc. variable pay Plan document(s).

Award Payments

To receive an award several criteria must be met:

Employment—To be eligible to receive an award, the individual must be employed by Patterson

Companies, Inc., or a subsidiary thereof, on the date awards are made;

Job elimination—Participants whose positions are eliminated may, at the discretion of management, be

eligible for prorated awards based on tenure in the qualifying position, overall performance level, actual
results attained, and other criteria determined by management;

Job transfer—Participants who transfer into or out of eligible positions within the Company may be
eligible for prorated awards based on tenure in the qualifying position, overall performance level, actual
results attained, and management discretion;

Performance—Continued participation in the Plan is dependent upon the participant remaining an
employee in good standing as defined by Patterson Companies, Inc. or its subsidiary. To qualify for an
award, a participant must have a satisfactory performance rating and not be on a formal performance
improvement plan. A participant on written warning or disciplinary status at any time during the Plan year
may have his/her incentive award reduced or denied at management’s discretion;

Ethical and Legal Standards—Participants are required to be in compliance with, and abide by,

Patterson Companies, Inc. Code of Ethics and comply with the letter and spirit of its provisions at all times.

No awards are considered earned until they are paid.

BASIS FOR AWARDS

The management of Patterson Companies, Inc. will approve participant objectives and evaluate performance

of the business unit. Performance will be evaluated based on the specific goals and measures described in the
attached plan schedules, the effective management of customer and employee relations, and compliance with
Company expectations of good business practices and ethical conduct.

Patterson Companies, Inc. reserves the right to make changes to the Plan at any time, including but not

limited to: withdraw or withhold from the Plan any transaction, product or service it might select; revise
territories; establish specific account, customer, or portfolio representation; and assign or reassign specific
accounts, customers, or portfolios within a participant’s location service area at any time during the fiscal year.

Goals, incentive targets, territory assignments, and any other factors affecting this Plan may be reviewed

and changed at any time during the Plan year.

APPROVAL OF AWARD PAYMENTS

The President of each respective subsidiary or operating unit will review and approve all award
recommendations prior to submission to payroll for payment. Management may adjust payments at its own
discretion to reflect the impact of any event that distorts actual results achieved and effective management of
customer and employee relations. All awards are paid at the discretion of management.

DISTRIBUTION OF AWARD PAYMENTS

Generally, awards are calculated following the end of the fiscal year and payments are scheduled within 75

days after the end of the fiscal year.

Award payments are made by the same means as the individual’s normal payroll. Applicable withholdings

are deducted from all payments. Payments made under this Plan will be used in the calculation of benefits only as
allowed under the applicable benefit plan. Awards are considered as earned by the participant on the date of
actual distribution.

Generally, awards are determined and paid according to the provisions of this Plan document. Any

exceptions require the approval of the President of each respective subsidiary or operating unit.

CHANGES IN EMPLOYMENT STATUS

In the event a participant dies, becomes disabled (as defined by Patterson’s Group Long Term Disability

Plan provisions), retires, or is on a leave of absence (as defined by applicable Patterson policies), he/she may be
eligible for an award based on management’s discretionary review of the participant’s actual performance and
actual work done while at work. In the event of death, the award payment, if any, is issued in the name of the
deceased and made payable to the estate.

ADOPTION AND ADMINISTRATION

The President and Chief Executive Officer of Patterson Companies, Inc., and the President of the subsidiary

or operating unit, or the Vice President—Human Resources on their behalf, must approve the attached Plan
schedules. The Plan schedules are effective for each fiscal year of the Company and are updated annually.

The President of each respective subsidiary or operating unit holds general authority and on-going
responsibility for Plan administration. Any exceptions to the provisions in this Plan require approval of the
President of Patterson Companies, Inc. and the President of the respective subsidiary or operating unit. The

foregoing officers and the Executive Vice President of Patterson Companies, Inc., or the Vice President of
Human Resources acting on their behalf, have the authority to interpret the terms of this Plan.

This Plan supersedes all prior Incentive Plans. No agreements or understandings will modify this Plan
unless they are in writing and approved by the President and Chief Executive Officer of Patterson Companies,
Inc. and the President of the respective subsidiary or operating unit. This Plan is reviewed annually to determine
the appropriateness of future continuation.

NO CONTRACT

Participation in this Plan does not constitute a contract of employment and shall not affect the right of
Patterson Companies, Inc. to discharge, transfer, or change the position of a participant. The employment of any
person participating in the Plan may be terminated at any time and no promise or representation is made
regarding continued employment because of participation in the Plan.

The Plan shall not be construed to limit or prevent Patterson Companies, Inc. from adopting or changing,

from time to time, any rules, standards, or procedures affecting a participant’s employment with Patterson
Companies, Inc. or any Patterson Companies, Inc. affiliate, including those which affect award payments, with or
without notice to the participant.

ETHICAL AND LEGAL STANDARDS

A participant shall not pay, offer to pay, assign or give any part of his/her compensation or any other money

to any agent, customer, or representative of the customer or any other person as an inducement or reward for
assistance in making a sale. Moreover, no rights under this Plan shall be assignable or subject to any pledge or
encumbrance of any nature.

If a participant fails to comply with the Patterson Companies, Inc. Code of Ethics or the provisions included

in this Plan document or violates any other Company policy, his/her award may be adjusted, reduced, or denied
at the discretion of Patterson Companies, Inc. management.

This	report	contains	forward-looking	statements	as	
defined	in	the	Private	Securities	Litigation	Reform	Act	
of	1995.	Forward-looking	statements	are	information	
of	a	non-historical	nature	and	are	subject	to	risks	and	
uncertainties	which	are	beyond	the	Company’s	ability	
to	control.	The	Company	cautions	shareholders	and	
prospective	investors	that	the	following	factors,	among	
others,	may	cause	actual	results	to	differ	materially	from	
those	indicated	by	the	forward-looking	statements:	the	
ability	to	integrate	recent	acquisitions	into	Patterson’s	
operations	in	a	timely	manner;	competition	within	
the	dental,	veterinary,	and	rehabilitative	and	assistive	
living	supply	industries;	changes	in	the	economics	of	
dentistry,	including	reduced	growth	in	expenditures	by	
private	dental	insurance	plans,	the	effects	of	economic	
conditions	and	the	effects	of	healthcare	reform,	which	
may	affect	future	per	capita	expenditures	for	dental	
services	and	the	ability	and	willingness	of	dentists	
to	invest	in	high-technology	products;	the	effects	of	
healthcare	related	legislation	and	regulation	which	may	
affect	expenditures	or	reimbursements	for	rehabilitative	
and	assistive	products;	changes	in	the	economics	of	the	
veterinary	supply	market,	including	reduced	growth	
in	per	capita	expenditures	for	veterinary	services	and	
reduced	growth	in	the	number	of	households	owning	
pets;	the	ability	of	the	Company	to	maintain	satisfactory	
relationships	with	its	sales	force;	unexpected	loss	of	key	
senior	management	personnel;	unforeseen	operating	
risks;	and	risks	associated	with	the	dependence	on	
manufacturers	of	the	Company’s	products.	Forward-
looking	statements	are	qualified	in	their	entirety	by	the	
cautionary	language	set	forth	in	the	Company’s	filings	
with	the	Securities	and	Exchange	Commission.
