General

      PETsMART was incorporated in Delaware on August 11, 1986, and we opened our first two stores in March 1987. In fiscal 2004, we generated sales of $3.4 billion, making PETsMART the leading provider of products, services and solutions for the lifetime needs of pets in North America. We opened 83 net new stores in fiscal 2004 and, as of January 30, 2005, operated 726 retail stores in North America. Our stores typically range in size from 19,000 to 27,000 square feet. Our stores carry a broad and deep selection of high quality pet supplies at everyday low prices. We offer more than 12,900 distinct items, including nationally recognized brand names, as well as an extensive selection of private brands across a range of product categories.

      We complement our extensive product assortment with a selection of value-added pet services, including grooming, pet training, boarding and day camp. Virtually all our stores offer complete pet training services and feature pet styling salons that provide high-quality grooming services. Through our strategic relationship with Banfield, The Pet Hospital, operating under the registered trademark of Banfield, we make full-service veterinary care available in approximately 430 of our stores.

      We also reach customers through our direct marketing channels, including PETsMART.com, one of the Internet’s most popular pet e-commerce sites, as well as an e-commerce site dedicated to equine products and two major branded catalogs.

      We have identified a large group of pet owners we call “pet parents,” who are passionately committed to their pets and consider their pets family members. Our strategy is to attract and keep these customers by becoming the preferred provider of Total Lifetime Care^sm for pets. As part of this strategy, we focus on driving efficiencies in our stores, on our processes and our systems, on growing our pet services business and on delighting our customers by providing a superior store environment, a superior shopping experience and superior service. We have improved our distribution capabilities, implemented new management information systems, focused on developing our pet services business and worked to develop a culture of customer service. In fiscal 2003, we completed the reformatting of our stores to create a specialty store environment by organizing the store by pet species, placing a greater emphasis on pet services and eliminating most of the high steel shelving, resulting in a brighter and more open store. Our store format, combined with our enhanced distribution and information systems capabilities, has reduced inventories, made the store easier to shop and

allowed our associates to spend more time serving customers. We believe these strategic initiatives will continue to drive enhanced comparable store sales growth, profitability and return on investment.

The Pet Food and Pet Supply Industry

      The pet product industry serves a large and growing market. The American Pet Products Manufacturers Association or APPMA, estimated the 2004 market at approximately $34.4 billion, an increase of over 100% since 1994. Based on the 2005/2006 APPMA National Pet Owners Survey, more than 69 million households in the United States own a pet. This translates to approximately 91 million cats and 74 million dogs. The APPMA also estimates 63% of United States’ households own a pet and 45% of those households own more than one type of pet.

      The pet product industry can be divided into the following categories: food, supplies/medicines, veterinary care, pet services (such as grooming or boarding) and purchases of pets. The APPMA estimates dog food, cat food and treats are the largest volume categories of pet-related products and in 2004 approximated $14.2 billion, or more than 40% of the market. Many premium pet food brands, which offer higher levels of nutrition than non-premium brands, are not currently sold through supermarkets, warehouse clubs and mass merchandisers due to manufacturers restrictions, but are sold primarily through superstores, specialty pet stores, veterinarians and farm and feed stores.

      Pet supplies and medicine sales account for approximately 24%, or $8.1 billion, of the market. These sales include dog and cat toys, collars and leashes, cages and habitats, books, vitamins and supplements, shampoos, flea and tick control and aquatic supplies. Veterinary care, pet services and purchases of pets represent approximately 23%, 7% and 5%, respectively, of the market.

Competition

      Based on total sales, we are the largest specialty retailer of pet food, supplies and services in North America. The pet food and pet supply retail industry is highly competitive and can be categorized into five different segments:

      We believe the principal competitive factors influencing our business are product selection and quality, convenience of store locations, store environment, customer service, price and availability of pet services. Many of the products we offer are not currently available in supermarkets, warehouse clubs or other mass and retail merchandisers. We believe we compete effectively within our various markets; however, some of our mass and retail merchandise competitors are larger in terms of overall sales volume and have access to greater capital.

      We are currently the only major specialty pet retailer that markets to customers through stores, catalogs and the internet, and we believe this gives us a competitive advantage. In addition, we believe our pet services business, which supermarkets, warehouse clubs and other mass and retail merchandisers cannot easily duplicate, is a competitive advantage.

Our Strategy

      Our strategy is to be the preferred provider for the lifetime needs of pets. Our primary initiatives include:

      Add stores in existing multi-store, new multi-store and new single-store markets. Our expansion strategy includes increasing our share in the top 60 existing multi-store markets, penetrating new multi-store and single-store markets and achieving operating efficiencies and economies of scale in distribution, procurement,

marketing and store operations. During 2004, we opened 83 net new stores, and in 2005, we expect to open approximately 100 net new stores primarily in multi-store markets. Approximately 35% of those store openings are planned in markets in the Northeast and California where we are significantly under-represented. We believe there is a potential for at least 1,400 PETsMART stores in North America.

      Provide the right store format to meet the needs of our customers. We completed the conversion of our store base to our new specialty store format in fiscal 2003. We believe our reformatted stores, combined with our other strategic initiatives, contribute to higher comparable store sales growth, profitability and return on investment. We continually evaluate our store format to ensure we are meeting the needs and expectations of our customers, while providing a return on investment to our shareholders. In fiscal 2004, we completed the roll out of an upgraded sign package to better serve the needs of our customers.

      Expand our pet services business. Based on sales, we are the leading provider of pet services, which includes professional grooming, pet training, boarding and day camp. Pet services are an integral part of our strategy, and we are focused on driving profitable growth in our services business. We believe services differentiate us from our competitors, drive traffic and repeat visits to our stores, provide cross-selling opportunities, allow us to forge a strong relationship with our customers, increase transaction size and enhance operating margins. Through our strategic relationship with Banfield, The Pet Hospital, operating under the registered trademark of Banfield, we make full-service veterinary care available in approximately 430 of our stores.

      Pet services revenue, which includes grooming, pet training, PETsHOTEL and Doggie Day Camp, grew by 24%, 25% and 29% in 2004, 2003 and 2002, respectively. We are confident in our ability to continue to expand the pet services portion of our business.

      Offer superior customer service. Our emphasis on the customer is an on going cultural shift designed to provide our customers with an unparalleled shopping experience every time they visit our stores. Using a detailed curriculum and role-playing techniques, we educate store associates to identify customer needs and provide solutions. We measure their success in every store, and a portion of the annual incentive program for managers, from the store level to the executive team, is linked to key customer service metrics. By providing pet parents with expertise and solutions, we believe we are strengthening our relationships with customers, building loyalty and enhancing our leading market position.

      Differentiate ourselves through effective brand management. We are focused on developing and strengthening our brand identity. We are creating tools to effectively communicate our unique value proposition and vision of providing Total Lifetime Care for pets, and to build enduring relationships with our customers. We continue to roll out our customer loyalty program, the PetPerks® savings card. As of January 30, 2005, PetPerks was available in over 315 stores and 22 markets, and by the third quarter of fiscal 2005, we intend to make the PetPerks card available in every PETsMART store capturing 70% to 80% of transactions and 75% to 85% of sales. We will continue using a centralized customer database that allows us to track and analyze customer shopping patterns. We intend to use this information to customize direct marketing and promotional materials and to more effectively communicate with customers across all channels.

Our Stores

      Our stores are generally located in sites co-anchored by strong destination superstores and typically are in or near major regional shopping centers. We are engaged in an ongoing expansion program, opening new stores in both new and existing markets and relocating existing stores. Store activity for fiscal 2004, 2003 and 2002 is as follows:

      In its first full year, we expect a new store to generate approximately $3.0 million in sales. We expect new stores to generate comparable store sales growth in the range of 19% to 21% in year two, 11% to 13% in year three, 7% to 8% in year four and 5% to 6% in year five. We believe there is a potential for a total of at least 1,400 PETsMART stores in North America. We expect to open approximately 100 net new stores in fiscal 2005.

Distribution

      We currently employ a hybrid distribution system including full truckload shipments to individual stores and the splitting of full truckloads among several closely located stores and distribution centers. Our forward distribution centers handle products that require rapid replenishment. Our improved distribution network, combined with improved and integrated information systems, drives reduced store inventory, more efficient use of store labor, improved in-stock positions and better distribution center productivity. Our suppliers generally ship our merchandise to one of our distribution centers or forward distribution centers, which receive and allocate merchandise to our stores. We contract the transportation of merchandise from our distribution centers to stores through third party vendors, and we do not own any trailers. We operate the following distribution centers:

      In September 2004, we entered into an agreement to lease approximately 1.0 million square feet in Ottawa, Illinois to be used as a distribution center. We anticipate opening this distribution center in the Fall of 2005.

Information Systems

      During fiscal 2004, we began deployment of an enhanced solution for the telephony needs in our new stores and certain existing stores. The new technology employs automatic call distribution features and wireless handsets that allow customer calls to be routed more efficiently to the proper area of the store. We believe this will enhance the customer experience in our stores.

      During fiscal 2004, we initiated a multi-year project to roll out pricing label and inventory control systems at our stores that will provide us with real time capabilities for inventory updates and better price control. This project will be completed in fiscal 2005.

      In addition, we implemented a voice recognition and new technology radio frequency solution for picking product in all but one of our distribution centers. The implementation of the remaining distribution center will occur in fiscal 2005. We believe this solution will contribute to increased speed and accuracy of this function and improve the capacity of our supply chain.

      Also during fiscal 2004, we completed the implementation of price optimization software to manage base prices and PetPerks prices. In addition, we completed the implementation of a new system to support our internet business, which we believe provides a solid foundation for future growth.

Merchandise

      Merchandise, which represented approximately 93% of our revenues in 2004 and 94% of our revenues in 2003 and 2002, generally falls into three main categories:

Pet Services

      Pet services, which include grooming, pet training, PETsHOTEL and Doggie Day Camp, represented approximately 7%, 6% and 6% of our revenues in 2004, 2003 and 2002, respectively. We offer full-service grooming and pet training services in virtually all our stores. We typically allocate an average of 779 square feet per store for high-quality, full-service grooming, including precision cuts, baths, toenail trimming and toothbrushing. Our pet stylists are trained through a 15-week program that teaches exceptional grooming skills using safe and gentle techniques. Pet training services range from puppy classes to advanced and private courses.

      PETsHOTEL provides boarding for dogs and cats, 24-hour supervision, an on-call veterinarian, temperature controlled rooms and suites, daily specialty treats and play time as well as day camp for dogs. During the third quarter of 2004, we decided to begin a national rollout of PETsHOTEL at selected locations in 2005. As of January 30, 2005, we operated 16 PETsHOTELs within our retail stores and one stand-alone location. In October 2004, we launched our test of the Doggie Day Camp concept, which is also available at our PETsHOTEL locations, at a retail store in Pasadena, California. We will continue to evaluate the results in fiscal 2005.

      Total revenues from pet grooming, pet training, boarding and day camp services grew approximately 24% from $193.5 million in 2003 to $240.7 million in 2004.

Veterinary Services

      The availability of comprehensive veterinary care in our stores further differentiates us and reflects our overall commitment to pet care. Full-service veterinary hospitals in approximately 430 of our stores offer routine examinations and vaccinations, dental care, a pharmacy and routine and complex surgical procedures. Substantially all these hospitals are operated by Medical Management International, Inc., or MMI, a third-party operator of veterinary hospitals, operating under the registered trade name of Banfield, The Pet Hospital. See Note 4 of the Notes to the Consolidated Financial Statements for a discussion of our ownership interest in MMI Holdings.

PETsMART Charities and Adoptions

      Through PETsMART Charities, Inc., an independent 501(c)(3) organization, we support the activities of animal welfare organizations in North America. PETsMART Charities creates and supports programs that intend to help find a lifelong loving home for every pet, by:

      Since 1994, PETsMART Charities has raised and donated more than $35 million to animal welfare programs and, through our in-store adoption programs, has saved the lives of more than 2 million pets.

Government Regulation

      We are subject to various federal, state, provincial and local laws and regulations governing, among other things: our relationships with employees, including minimum wage requirements, overtime, working conditions and citizenship requirements; veterinary practices, or the operation of veterinary hospitals in retail stores, that may impact our ability to operate veterinary hospitals in certain facilities; the transportation, handling and sale of small pets; environmental regulations with respect to generation, handling, storage, transportation and disposal of waste and biohazardous materials; the distribution, import/export and sale of products; the handling, security, protection and use of customer information; and the licensing and certification of services.

      While we seek to structure our operations to comply with all federal, state, provincial and local laws and regulations of each jurisdiction in which we operate, there can be no assurances that, given varying and uncertain interpretations of these laws and regulations and the fact that the laws and regulations are enforced by the courts and by regulatory authorities with broad discretion, we would be found to be in compliance in all jurisdictions. We also could be subject to costs, including fines, penalties or sanctions and third party claims as a result of violations of, or liabilities under, these laws and regulations.

Intellectual Property

      We have several service marks and trademarks registered with the United States Patent and Trademark Office (or USPTO), including PETsMART®, PETsMART.com®, PETsMART PETsHOTEL®, Where Pets Are Family® and All You Need For The Life Of Your Pet®, as well as many others. We also own several service mark and trademark applications that are pending with the USPTO and anticipate filing additional applications in the future. We also own numerous registered service marks, trademarks and pending applications in other countries, including Canada, as well as several trade names, domain names and copyrights for use in our business. We regard our intellectual property as having significant value and as an important component in our merchandising and marketing strategies.

Employees

      As of January 30, 2005, we employed approximately 30,300 associates, approximately 15,100 of whom were employed full time. We are not subject to any collective bargaining agreements and have not experienced any work stoppages. We consider our relationship with our associates to be good. Increases in the federal minimum wage in recent years have not had a material effect on our business.

Financial Information by Business Segment and Geographic Data

      As of February 2, 2004, we had three operating segments; PETsMART North America, which included all retail stores; PETsMART Direct, which included our equine catalog and equine Internet operations; and PETsMART.com, which included our pet catalog and pet Internet operations. As of January 30, 2005, we had two operating segments as a result of the integration of PETsMART Direct and PETsMART.com during the first quarter of fiscal 2004. We evaluated our segment reporting requirements under SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information,” and determined that the reorganized

PETsMART Direct operating segment does not meet the quantitative thresholds for disclosure as a reportable operating segment.

      Net sales in the United States were approximately $3,275.8 million, $2,917.3 million and $2,632.5 million for 2004, 2003 and 2002, respectively. Net sales, denominated in US dollars, in Canada were approximately $87.7 million, $75.7 million and $62.7 million for 2004, 2003 and 2002, respectively.

Available Information

      We make available, free of charge through our internet web-site (www.petsmart.com), our Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q, our current reports on Form 8-K and amendments to those reports, as soon as reasonably practicable after we electronically file such material, or furnish it to the Securities and Exchange Commission.

      All PETsMART associates must act ethically at all times and in accordance with the policies which comprise PETsMART’s Code of Business Ethics and Policies. We require full compliance with this policy, and all designated associates including our Principal Executive Officer, Principal Financial Officer, Principal Accounting Officer and such other individuals performing similar positions, have signed a certificate acknowledging that they have read, understand and will continue to comply with the policy. The policy is published and any amendments or waivers thereto will be published in the Corporate Governance section of the PETsMART website located at www.petm.com.

Business Risks

      In the normal course of business, our financial position is routinely subjected to a variety of risks, including market risks associated with store expansion, investments in information systems, international expansion, vendor reliability, competitive forces and government regulatory actions. You should carefully consider the risks and uncertainties described below in connection with those also discussed in Our Stores, Distribution, Information Systems, Competition and Government Regulation sections of this Annual Report on Form  10-K. Our actual results could differ materially from projected results due to some or all of the factors discussed below.

      Our continued revenue growth depends to a degree on our ability to increase sales at our stores. There can be no assurance that our stores will meet forecasted levels of sales and profitability.

      In addition, we expect to open approximately 100 net new stores in 2005. Our ability to open additional stores is dependent on various factors including:

      To the extent we are unable to accomplish any of the above, our ability to open new stores may be harmed. In addition, there can be no assurance that we will be able to operate our new stores profitably.

New stores may erode sales at existing stores and comparable store sales growth may decrease as stores grow older.

      We currently operate stores in most of the major market areas of the United States and Canada. Our plans for 2005 include opening 100 net new stores, primarily in existing multi-store markets. Approximately 35% of those store openings are planned in markets in the Northeast and California where we are significantly under-represented. It has been our experience that opening new stores may attract some customers away from other stores already operated by us in those markets and diminish their sales. Our comparable store sales increases were 6.3% and 7.0% for fiscal years 2004 and 2003, respectively. As a result of new store openings in existing markets, and because older stores will represent an increasing proportion of our store base over time, our comparable store sales increases may be lower or sales could decrease in future periods.

Our operating margins at new stores may be lower than those of existing stores.

      Preopening expenses and lower sales volumes associated with newly opened stores can impact operating margins. In addition, we expect certain operating costs, particularly those related to occupancy, to be higher in new stores than in the past in some newly entered geographic regions. As a result of our increasing number of net new stores and the impact of these rising costs, our total store contribution and operating margins may be lower in future periods than they have been in the past.

A disruption, malfunction, or increased costs in the operation or expansion of our distribution centers or our supply chain would impact our ability to deliver merchandise to our stores or increase our expenses, which could harm our sales and results of operations.

      Our suppliers generally ship our merchandise to one of our distribution centers, which receive and allocate merchandise to our stores. Any interruption or malfunction in our distribution operations, including, but not limited to, the loss of a key vendor that provides transportation of merchandise from our distribution centers to stores, could harm our sales and the results of our operations. We have two fish distribution centers that are operated by a third-party vendor, and an interruption or malfunction to their business could harm our sales and results of operations. In such an event, there can be no assurance that we could contract with another third party to operate the fish distribution centers on favorable terms, if at all, or that we could successfully operate the fish distribution centers ourselves. In addition, if we are unable to successfully expand our distribution centers, our sales or results of operations could be harmed.

If our information systems fail to perform as designed, our business could be harmed.

      The efficient operation of our business is dependent on our information systems. In particular, we rely on our information systems to effectively manage our sales, warehousing, distribution, merchandise planning and replenishment functions and to maintain our in-stock positions. We possess offsite recovery capabilities for our information systems. The failure of our information systems to perform as designed could disrupt our business and harm our sales and profitability.

      We continue to invest in our information systems. There can be no assurance that the costs of investments in our information systems will not exceed estimates or that they will be as beneficial as predicted. If we are unable to realize the benefits of improved systems, our results of operations could be harmed.

A decline in consumers’ discretionary spending could reduce our sales and harm our business.

      Our sales depend on consumer spending, which is influenced by factors beyond our control, including general economic conditions, the availability of discretionary income, weather, consumer confidence and unemployment levels. We may experience declines in sales during economic downturns. Any material decline in the amount of discretionary spending could reduce our sales and harm our business.

Our results may fluctuate due to seasonal changes associated with the pet food and pet supply retailing industry and the timing of expenses, new store openings and store closures.

      Our business is subject to seasonal fluctuation. We typically realize a higher portion of our net sales and operating profit during the fourth fiscal quarter. As a result of this seasonality, we believe that quarter-to-quarter comparisons of our operating results are not necessarily meaningful and that these comparisons cannot be relied upon as indicators of future performance. Controllable expenses, such as advertising, could fluctuate from quarter-to-quarter within a fiscal year. Sales of certain products and services designed to address pet health needs are seasonal. Because our stores typically draw customers from a large trade area, sales may also be impacted by adverse weather or travel conditions, which are more prevalent during certain seasons of the year. Finally, as a result of our expansion plans, the timing of new store openings and related preopening expenses, the amount of revenue contributed by new and existing stores, and the timing and estimated obligations of store closures, our quarterly results of operations may fluctuate.

The pet food and pet supply retail industry is highly competitive, and continued competitive forces may reduce our sales and profitability.

      The pet food and pet supply retail industry is highly competitive. We compete with supermarkets, warehouse clubs and mass and other retail merchandisers, many of which are larger and have significantly greater resources than we have. We also compete with a number of pet supply warehouse or specialty stores, smaller pet store chains, catalog retailers, internet retailers and pet stores. The industry has become increasingly competitive due to the entrance of other specialty retailers into the pet food and pet supply market, some of which have developed store formats similar to ours, and due to the expansion of pet-related product offerings by certain supermarkets, warehouse clubs and mass and other retail merchandisers. There can be no assurance we will not face greater competition from these or other retailers in the future. In particular, if any of our major competitors seek to gain or retain market share by reducing prices, we would likely reduce our prices in order to remain competitive, which may result in a decrease in our sales and profitability and require a change in our operating strategies.

The loss of any of our key vendors, a decision by our vendors to make their products available in supermarkets or through warehouse clubs and mass merchandisers, or the inability of our vendors to provide products in a timely or cost-effective manner, could harm our business.

      We have no long-term supply commitments from our vendors. We buy from several hundred vendors worldwide and, together, our two largest vendors accounted for approximately 15.2% of our total sales for fiscal 2004. Sales of premium pet food for dogs and cats comprise a significant portion of our revenues. Currently, most major vendors of premium pet foods do not permit their products to be sold in supermarkets, warehouse clubs or through other mass merchandisers. If any premium pet food or pet supply vendors were to make their products available in supermarkets or through warehouse clubs and mass merchandisers, our business could be harmed. In addition, if the grocery brands currently available to such retailers were to gain market share at the expense of the premium brands sold only through specialty pet food and pet supply outlets, our business could be harmed.

      We purchase significant amounts of pet supplies from a number of vendors with limited supply capabilities. There can be no assurance that our current pet supply vendors will be able to accommodate our anticipated needs or comply with existing or any new regulatory requirements. In addition, we purchase significant amounts of pet supplies from vendors outside of the United States. There can be no assurance our overseas vendors will be able to satisfy our requirements including, but not limited to, timeliness of delivery, acceptable product quality, packaging and labeling requirements. Any inability of our existing vendors to provide products in a timely or cost-effective manner could harm our business. While we believe our vendor relationships are satisfactory, any vendor could discontinue selling to us at any time.

We depend on key personnel and may not be able to retain or replace these employees or recruit additional qualified personnel, which could harm our business.

      Our success is largely dependent on the efforts and abilities of our senior executive group. The loss of the services of one or more of our key executives could adversely impact our financial performance and our ability to execute our strategies. In addition, our future success will depend on our ability to attract highly skilled store managers and qualified services personnel such as pet trainers and groomers. There is a high level of competition for these employees, and our ability to operate our stores and expand these services depends on our ability to attract and retain these personnel. In addition, historically there has been a shortage of qualified veterinarians. If Banfield cannot attract and retain a sufficient number of veterinarians, Banfield’s ability to provide veterinary services in our stores and increase the number of stores in which Banfield provides veterinary services, may be impacted.

      We entered the Canadian market in 1996 and operated 25 stores in Canada as of January 30, 2005. As these operations grow, they may require greater management and financial resources. International operations require the integration of personnel with varying cultural and business backgrounds and an understanding of the relevant differences in the legal and regulatory environments. Our results may be increasingly affected by the risks of our international activities, including:

Our business may be harmed if the operation of veterinary hospitals at our stores is limited or fails to continue.

      We and MMI, the third party operator of Banfield, The Pet Hospital, are subject to laws governing the operation of veterinary hospitals. MMI Holdings, Inc., or MMIH, is the parent company of MMI. Statutes and regulations in various states and Canadian provinces regulating the ownership of veterinary practices, or the operation of veterinary hospitals in retail stores, may impact our ability and MMI’s ability to operate veterinary hospitals within our facilities. A determination that we or MMI are in violation of any of these applicable statutes and regulations could require us or MMI to restructure our operations to comply or render us or MMI unable to operate veterinary hospitals in a given location. We recorded $13.1 million and $10.5 million from MMI during 2004 and 2003, respectively, as a reduction of the retail stores’ occupancy costs. We record store occupancy costs as a component of cost of sales in our consolidated financial statements. If MMIH or MMI were to experience financial or other operating difficulties that would force it to limit its operations, or if MMIH were to cease operating the veterinary hospitals in our stores, our business may be harmed, both directly and due to a decrease in customer traffic. There can be no assurance that we could contract with another third party to operate the veterinary hospitals on favorable terms, if at all, or that we could successfully operate the veterinary hospitals ourselves. For a further discussion of our relationship with MMI, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Related Party Transactions.”

Our business would be harmed if we were unable to raise any needed additional capital on acceptable terms.

      We anticipate that our existing capital resources and cash flows from operations will enable us to maintain our currently planned operations for the foreseeable future. If, however, we are unable to generate and maintain positive operating cash flows and operating income in the future, we may need additional

funding. We may also choose to raise additional capital due to market conditions or strategic considerations even if we believe that we have sufficient funds for our current or future operating plans. Our current credit facility is secured by substantially all of our personal property assets, our subsidiaries and certain real property. This could limit our ability to obtain, or obtain on favorable terms, additional financing and may make additional debt financing outside our credit facility more costly. If additional capital were needed, an inability to raise capital on favorable terms would harm our business and financial condition. In addition, to the extent that we raise additional capital through the sale of equity or debt securities convertible into equity, the issuance of these securities could result in dilution to our stockholders.

A determination that we are in violation of any government regulations could require us to restructure our operations to comply in a given government jurisdiction and could harm our business.

      We are subject to various federal, state, provincial and local laws and regulations governing among other things: our relationships with employees, including minimum wage requirements, overtime, working conditions and citizenship requirements; veterinary practices, or the operation of veterinary hospitals in retail stores, that may impact our ability to operate veterinary hospitals in certain facilities; the transportation, handling and sale of small pets; environmental regulations with respect to the generation, handling, storage, transportation and disposal of waste and biohazardous materials; the distribution, import/export and sale of products; the handling, security, protection and use of customer information; and the licensing and certification of services.

      While we seek to structure our operations to comply with all federal, state, provincial and local laws and regulations of each jurisdiction in which we operate, there can be no assurances that, given varying and uncertain interpretations of these laws and regulations and the fact that the laws and regulations are enforced by the courts and by regulatory authorities with broad discretion, we would be found to be in compliance in all jurisdictions. We also could be subject to costs, including fines, penalties or sanctions and third party claims as a result of violations of, or liabilities under, the above referenced laws and regulations.

A determination by tax regulators on an issue may cause our provision for income and other taxes to be inadequate and may result in a material impact to our financial position.

      We operate in multiple tax jurisdictions and believe an adequate provision for income and other taxes has been made. If, however, a determination is made by tax regulators in these jurisdictions that a position that we have taken on an issue is inappropriate, this may result in a material impact to our financial position. The Internal Revenue Service is currently examining our tax returns for the 2002 tax year.

      We are occasionally subject to claims due to the injury or death of a pet in our stores or while under our care in connection with the pet services we provide. In addition, we sell certain small pets including fish, birds, reptiles and small rodents in our stores. Given the large number of small pets we sell, deaths or injuries of these small pets sometimes occur while they are within our care. As a result, we may be subject to claims that we do not properly care for these small pets. We may also be subject to claims resulting from the transfer of diseases from pets in our stores to other animals, associates and customers. In addition, from time to time, we have been subject to product liability claims for some of the products we sell. Any negative publicity or claims relating to any of the foregoing could harm our reputation and business, as well as expose us to litigation expenses and damages.

Pending legislation, weather, disease or other factors could disrupt the supply of the small pets and products we sell, which could harm our reputation and decrease sales.

      There is generally a significant amount of legislation pending at the federal, state, provincial and local levels regarding the handling of pets. This legislation may impair our ability to transport the small pets we sell in our stores. The small pets we sell in our stores are susceptible to diseases that can quickly decrease or destroy the supply of these pets. In addition, our supply of products may be negatively impacted by weather,

disease, contamination or trade barriers. Any disruption in the supply of products to our stores, due to legislation, weather, disease or any other factor, could harm our reputation and decrease our sales.

      Over the last several years, the market price of our common stock has been subject to significant fluctuations. The market price of our common stock may continue to be subject to significant fluctuations in response to operating results and other factors including, but not limited to:

      In addition, the stock market in recent years has experienced price and volume fluctuations that often have been unrelated or disproportionate to the operating performance of companies. These fluctuations, as well as general economic and market conditions, including but not limited to fuel costs, may harm the market price of our common stock.

      Our restated certificate of incorporation and bylaws include provisions that may delay, defer or prevent a change in management or control that our stockholders may not believe is in their best interests. These provisions include:

      In addition, our restated certificate of incorporation requires a 66²/3% vote of stockholders to:

      In August 1997, our Board of Directors adopted a Stockholder Rights Plan, commonly referred to as a poison pill, under which one preferred share purchase right was distributed on August 29, 1997, for each share of common stock held on that date. We are also subject to the anti-takeover provisions of Section 203 of the

Delaware General Corporation Law, and the application of Section 203 could have the effect of delaying or preventing an acquisition of PETsMART.

      Our stores are generally located in sites co-anchored by strong destination superstores and typically are in or near major regional shopping centers. The following table summarizes the locations of the stores by country and state at January 30, 2005:

      We lease substantially all of our stores, retail distribution centers and corporate offices under non-cancellable leases. The terms of the store leases, described below, generally range from 10 to 25 years and typically allow us to renew for three to five additional five-year terms. Store leases, excluding renewal options, expire at various dates through 2022. Certain leases require payment of property taxes, utilities, common area maintenance and insurance and, if annual sales at certain stores exceed specified amounts, provide for additional rent. We have paid minimal additional rent under these provisions.

      Our corporate offices cover approximately 219,000 square feet, and the leases expire beginning in 2009. Our distribution centers and respective lease expirations are as follows:

      We also own and operate an internet fulfillment, catalog fulfillment and equine distribution center in Brockport, New York, which covers approximately 392,000 square feet.

      In September 2004, we entered into an agreement to lease approximately 1.0 million square feet in Ottawa, Illinois to be used as a distribution center. We anticipate opening this distribution center in the Fall of 2005.

      We are involved in the defense of various legal proceedings that we do not believe are material to our business.

Overview

      Based on our 2004 sales of $3.4 billion, we are the leading provider of products, services and solutions for the lifetime needs of pets in North America. As of January 30, 2005, we operated 726 retail stores in North America, typically ranging in size from 19,000 to 27,000 square feet. During fiscal 2004, we opened 83 net new stores, and we anticipate opening approximately 100 net new stores in fiscal 2005. Our stores carry a broad and deep selection of high quality pet supplies at everyday low prices. We offer more than 12,900 distinct items, including nationally recognized brand names, as well as an extensive selection of private brands across a range of product categories. We continue to invest in education for our approximately 30,300 associates as part of our on-going cultural shift with an emphasis on customer service and providing pet care solutions.

      We complement our extensive product assortment with a wide selection of value-added pet services, including grooming, pet training, boarding and day camp. All our stores offer complete pet training services, and virtually all our stores feature pet styling salons that provide high-quality grooming services.

      We make full-service veterinary care available in approximately 430 of our stores through our strategic relationship with Banfield, The Pet Hospital, operating under the registered trademark of Banfield. During the third quarter of 2004, we decided to begin a national roll out of PETsHOTEL in 2005. As of January 30, 2005, we operated 16 PETsHOTELs within our retail stores and one stand-alone location. In October 2004, we launched our test of the Doggie Day Camp concept, which is also available at our PETsHOTEL locations, at a retail store in Pasadena, California, and we will continue to evaluate the results.

      We also reach customers through our direct marketing channels, including PETsMART.com, one of the Internet’s most popular pet e-commerce sites, an e-commerce site dedicated to equine products and two major branded catalogs.

Executive Summary

Critical Accounting Policies and Estimates

      The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an on-going basis, we evaluate our estimates for inventory valuation reserves, reserve for closed stores, insurance liabilities and reserves and income taxes. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Under different assumptions or conditions, actual results may differ from these estimates. We believe the following critical accounting policies reflect the more significant judgments and estimates we use in preparing our consolidated financial statements.

Inventory Valuation Reserves

      We have established reserves for estimated inventory shrinkage between physical inventories. Our stores perform physical inventories once a year, and in between the physical inventories, the stores perform cycle counts on certain inventory items. Our distribution centers and forward distribution centers perform cycle counts encompassing all inventory items every quarter or perform an annual physical inventory. Due to the holiday season, the majority of the stores do not perform physical inventories during the last quarter of the fiscal year, but continue to perform cycle counts on certain inventory items. Therefore, as of the end of a reporting period, there will be stores with certain inventory items that have not been counted. For each reporting period presented, we estimate the inventory shrinkage based on a two-year historical trend analysis. We also have reserves for estimated obsolescence and to reduce inventory to the lower of cost or market. Changes in shrink results or market conditions could cause actual results to vary from estimates used to establish the inventory reserves.

Reserve for Closed Stores

      We continuously evaluate the performance of our retail stores and periodically close those that are under-performing. The closed stores are generally replaced by a new store in a nearby location. We establish reserves for future occupancy payments on closed stores in the period the store is closed, in accordance with SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities” (“SFAS 146”). These costs are classified in operating, general and administrative expenses in the consolidated statement of operations. We calculate the costs for future occupancy payments, net of expected sublease income, associated with closed stores using the net present value method, at a credit-adjusted risk-free interest rate, over the remaining life of the lease. Judgment is used to estimate the underlying real estate market related to the expected sublease income and timing of the sublease start date, and we can make no assurances that additional charges for these stores will not be required based on the changing real estate environment.

      As of January 30, 2005 and February 1, 2004, we had 17 and 19 stores included in our closed store reserve, of which 12 and 12 were under sublease agreements, respectively. We have assumed that as of January 30, 2005, two additional stores will have sublease income in future periods, which represents a $2.4 million reduction to the reserve. If these sublease assumptions were extended by a year from the anticipated commencement date of the assumed sublease term, the reserve would increase by approximately $0.4 million. We closed nine stores in fiscal 2004 and seven stores in fiscal 2003, of which one store in fiscal 2003 closed as scheduled due to its lease expiration. The closed store reserves are as follows (in thousands):

Insurance Liabilities and Reserves

      We maintain standard property and casualty insurance on all our properties and leasehold interests, product liability insurance that covers products and the sale of live pets, self-insured health plans, employer’s professional liability and workers’ compensation insurance. Property insurance covers approximately $1.0 billion in buildings and contents, including furniture and fixtures, leasehold improvements and inventory. Under our casualty and workers’ compensation insurance policies through January 31, 2004, we retained the initial risk of loss of $0.25 million for each policy per occurrence. Effective February 1, 2004, we engaged a new insurance provider. Under our casualty and workers’ compensation insurance policies with the new provider, we retain an initial risk of loss of $0.5 million for each policy per occurrence on or subsequent to February 1, 2004. We establish reserves for losses based on semi-annual independent actuarial estimates of the amount of loss inherent in that period’s claims, including losses for which claims have been incurred but not reported. Loss estimates rely on actuarial observations of ultimate loss experience for similar historical events, and changes in such assumptions could result in an adjustment to the reserves. During the second quarter of 2004, we recognized additional expense as a result of an actuarial report that indicated a higher reserve requirement. We believe the increase in the actuarial estimates was primarily due to our insurance carrier being acquired resulting in an increase in the rate at which claims are paid as well as the settlement amounts. As of January 30, 2005 and February 1, 2004, we had approximately $40.6 million and $27.9 million, respectively, in reserves related to casualty, self-insured health plans, employer’s professional liability and workers’ compensation insurance policies.

Income Taxes

      We establish deferred income tax assets and liabilities for temporary differences between the financial reporting bases and the income tax bases of our assets and liabilities at enacted tax rates expected to be in effect when such assets or liabilities are realized or settled. We record a valuation allowance on the deferred income tax assets to reduce the total to an amount management believes is more likely than not to be realized. Valuation allowances at January 30, 2005 and February 1, 2004 were principally to offset certain deferred income tax assets for operating and capital loss carryforwards.

      We accrue for potential income tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated, based upon management’s view of the likely outcomes of current and future audits. Our accrual for income tax contingencies is adjusted for changes in circumstances and additional uncertainties, such as amendments to existing tax law, both legislated and concluded through the various jurisdictions’ tax court systems. At January 30, 2005, we had an accrual for income tax contingencies of approximately $17.0 million. If the amounts ultimately settled with tax authorities are greater than the accrued contingencies, we must record additional income tax expense in the period in which the assessment is determined. To the extent amounts are ultimately settled for less than the accrued contingencies, or we determine that a liability to a taxing authority is no longer probable, the contingency is reversed as a reduction of income tax expense in the period the determination is made.

      In the second quarter of 2004, we completed an analysis of our net operating loss carryovers related to our purchase of PETsMART.com in fiscal year 2000, based on guidance issued from the Internal Revenue Service. As a result, we expect to utilize an additional $22.1 million of net operating losses previously considered unavailable. We recorded a total tax benefit of $7.7 million in the second quarter of 2004 related to the additional net operating loss utilization.

      We operate in multiple tax jurisdictions and could be subject to audit in any of these jurisdictions. These audits can involve complex issues that may require an extended period of time to resolve and may cover multiple years. We believe an adequate provision for taxes has been made for all years subject to audit.

Results of Operations

      The following table presents the percent to net sales of certain items included in our consolidated statements of operations:

Fiscal 2004 Compared to Fiscal 2003

      Net sales increased $370.3 million, or 12.4%, to $3.4 billion for fiscal 2004, compared to sales of $3.0 billion for fiscal 2003. The sales increase was due to 83 additional net new stores since February 1, 2004 and a 6.3% increase in comparable store sales for 2004. Services sales, which is included in the net sales amount discussed above, increased by 24.4%, or $47.2 million, to $240.7 million.

      Gross profit increased as a percentage of net sales to 30.8% for fiscal 2004, from 30.0% for fiscal 2003. The increase primarily reflected higher margins on product sales during fiscal 2004 compared with fiscal 2003 due to improved buying practices and the results from our price optimization software, which is protecting and enhancing gross margins even as we pursue our loyalty card program. We also experienced lower inventory shrinkage and other inventory related expenses as a percentage of sales in fiscal 2004 compared to fiscal 2003. In addition, occupancy costs recorded in cost of sales decreased as a percentage of sales in fiscal 2004 compared to fiscal 2003. These items were partially offset by higher freight costs as a result of increased fuel prices.

      Operating, general and administrative expenses increased as a percentage of net sales to 22.4% for 2004, from 22.1% for 2003. The increase was primarily due to increases in workers’ compensation, general liability and medical insurance costs as well as higher repairs and maintenance costs in our stores in 2004 compared to 2003. The higher insurance costs were primarily due to increases in actuarial estimates for workers’ compensation and general liability claims. In addition, we recognized a $4.1 million expense in the second quarter of fiscal 2004 primarily for the retirement of assets and additional amortization related to store lighting replacements. The increases were offset by lower advertising, bonus and closed store expenses as a percentage of revenue in fiscal 2004 compared to fiscal 2003. We also recognized a $3.6 million gain from a legal settlement in the fourth quarter of 2004.

      Interest expense increased to $21.3 million for 2004, from $19.3 million for fiscal 2003. The increase was primarily due to an increase in capital lease obligations in 2004.

      For fiscal 2004, the $93.2 million income tax expense represents an effective rate of 35.2%. For 2003, the $85.7 million income tax expense represents an effective rate of 38.8%. The reduction in the effective tax rate from 2003 to 2004 is primarily due to an analysis, completed in the second quarter of 2004, of our net operating loss carryovers related to our purchase of PETsMART.com in fiscal 2000, based on guidance issued from the Internal Revenue Service. As a result, we expect to utilize an additional $22.1 million of net operating losses previously considered unavailable. We recorded a total tax benefit of $7.7 million in the second quarter of 2004, related to the additional net operating loss utilization. In addition, we recognized a $3.6 million legal settlement in the fourth quarter of fiscal 2004, which will allow us to use a portion of our capital loss carryforwards. We reversed a previously established valuation allowance, and as a result, recorded a tax benefit of approximately $1.2 million.

Fiscal 2003 Compared to Fiscal 2002

      Net sales increased $297.9 million, or 11.1%, to $3.0 billion for 2003, from 2002 sales of $2.7 billion. The increase was the result of 60 additional net new stores and a 7.0% increase in comparable store sales. Included in store sales, services sales increased by 25.4%, or $39.2 million to $193.5 million. The increase in services

revenue, which includes grooming, training and PETsHOTEL operations, was due primarily to higher volume. As of February 1, 2004, we operated 643 stores, compared with 583 stores as of February 2, 2003.

      Gross profit increased as a percentage of net sales to 30.0% for 2003, from 29.1% for 2002. The increase primarily reflected lower product cost of goods sold and increased sales of higher margin products during 2003, compared with 2002. We also continued to leverage expenses in 2003 through lower inventory shrinkage and occupancy costs as a percentage of sales, compared with 2002.

      Operating, general and administrative expenses decreased as a percentage of net sales to 22.1% for 2003, from 22.9% for 2002. In 2002, we recorded $11.4 million related to a litigation settlement and costs, which represented 0.4% of sales. In 2003, we leveraged payroll and benefits costs as well as decreased our bonus expenses compared to 2002. Reductions in equipment rent, and operating expenses in the direct marketing channels also drove the decrease. This reduction was partially offset by higher expenses associated with closed stores and the payment of a residual value guarantee on two land parcels. We closed seven stores in fiscal 2003, compared to four stores in fiscal 2002. The higher expense in 2003 was driven by a timing difference due to the application of SFAS 146, “Accounting for Costs Associated with Exit or Disposal Activities.” The plan to close two of the four stores in 2002, and the related expense recognition, took place at the end of fiscal 2002. In 2002, we adopted SFAS 146, which requires us to record closed store expense in the period that the store is actually closed.

      Interest expense decreased to $19.3 million for 2003, from $20.6 million for 2002. The decrease was primarily due to the retirement and conversion of our 6³/4% Subordinated Convertible Notes in the first quarter of 2002. For 2003, interest expense also included lower capital lease interest due to the expiration of certain capital lease obligations.

      For fiscal 2003, the $85.7 million income tax expense represents an effective rate of 38.8%. For 2002, the $62.6 million income tax expense represents an effective rate of 42.2%. The reduction in the effective tax rate from fiscal 2002 to fiscal 2003 is primarily due to certain non-deductible losses recognized in 2002 associated with the settlement of litigation.

Liquidity and Capital Resources

      The following table represents our cash and cash equivalents and short-term investments (in thousands):

      We manage our cash, cash equivalents and short-term investments in order to fund operating requirements. Cash and cash equivalents decreased $5.5 million to $87.0 million in 2004. Short-term investments increased $78.3 million to $313.6 million during the same period. In February 2005, we determined that investments in Auction Rate Securities, or ARS, should be classified as short-term investments. Previously, such investments had been classified as cash and cash equivalents. ARS generally have long-term maturities; however, these investments have characteristics similar to short-term investments because at predetermined

intervals, generally every 28 to 49 days, there is a new auction process. We recorded investments in ARS as of January 30, 2005 as short-term investments and reclassified ARS as of February 1, 2004 that were previously included in cash and cash equivalents to short-term investments.

      Cash provided by operations increased $36.8 million to $282.6 million in 2004, compared with $245.8 million in 2003. Cash provided by operating activities was generated primarily by net income of $171.2 million and non-cash depreciation and amortization expenses of $112.6 million. Cash is used in operating activities primarily to fund growth in inventory and other assets, net of accounts payable and other accrued liabilities. Inventory increased to $337.3 million at January 30, 2005 compared to $309.1 million at February 1, 2004 primarily due to the 83 net new stores in fiscal 2004.

      Our primary long-term capital requirements consist of opening new stores, reformatting existing stores, expenditures associated with equipment and computer software in support of our system initiatives, PETsHOTEL construction costs and other expenditures to support our growth plans and initiatives. For 2004, we incurred $143.0 million in capital expenditures, compared with $171.9 million for 2003. The 2004 expenditures were primarily related to new stores, remodel projects and information systems projects. In addition, we purchased equipment during fiscal 2004 that was previously leased.

      Net cash used in financing activities for 2004 was $69.0 million, which is comprised primarily of $80.0 million for the purchase of treasury stock and $15.9 million for dividends, offset by $40.0 million in proceeds from the exercises of stock options and from our employee stock purchase plan. Net cash used in financing activities for 2003 was $0.2 million.

      In April 2000, the Board of Directors approved a plan to purchase our common stock. In March 2003, the Board of Directors extended the term of the purchase of our common stock for an additional three years through March 2006 and increased the authorized amount of annual purchases to $35.0 million. In September 2004, the Board of Directors approved a program authorizing the purchase of up to $150.0 million of our common stock through fiscal year 2005. This program replaces the March 2003 program. During fiscal 2004, we purchased 2,680,778 shares of our common stock for approximately $80.0 million, or an average price of $29.84 per share, under the March 2003 and September 2004 programs. At January 30, 2005, approximately $105.0 million remained available for purchase under these programs.

      We believe our ability to generate cash allows us to invest in the growth of the business and, at the same time, distribute a quarterly dividend. Our credit facility permits us to pay dividends, so long as we are not in default and the payment of dividends would not result in default. During 2004, we were not in default of our credit facility. In fiscal 2004, the following dividends were declared by the Board of Directors:

      On March 22, 2005, the Board of Directors declared a quarterly cash dividend of $0.03 per share, payable on May 20, 2005 to stockholders of record on April 29, 2005.

      In July 2002, we filed a registration statement on Form S-3 for a public offering of 14,500,000 shares of our common stock, plus an over-allotment option of 2,175,000 shares. Of these shares, 13,182,584 were offered

by entities affiliated with Carrefour SA, and we offered 1,317,416 shares, plus the shares in the over-allotment option.

      On August 5, 2002, we completed the sale of the 1,317,416 shares of common stock for $13.40 per share, resulting in proceeds, net of underwriting fees, of approximately $16.9 million. On August 12, 2002, the underwriters exercised the over-allotment option and purchased 2,175,000 additional shares for $13.40 per share, resulting in proceeds, net of underwriting fees, of approximately $27.8 million. We incurred costs associated with the offering of approximately $0.8 million.

      Substantially all our stores are leased facilities. We opened 83 net new stores in fiscal 2004. Generally, each new store requires capital expenditures of approximately $0.9 million for fixtures, equipment and leasehold improvements, approximately $0.3 million for inventory and approximately $0.1 million for preopening costs. We expect capital spending to be approximately $220 million to $230 million for 2005, based on our current plan to open 100 net new stores and twelve new PETsHOTELs, to fixture and equip a new warehouse in Illinois, to continue our investment in the development of our information systems and to add to our services capacity with the expansion of certain grooming salons.

      We believe our existing cash and cash equivalents, together with cash flows from operations, borrowing capacity under our bank credit facility and available lease financing, will provide adequate funds for our foreseeable working capital needs, planned capital expenditures and debt service obligations. Our ability to fund our operations, make planned capital expenditures, scheduled debt payments and refinance indebtedness depends on our future operating performance and cash flow, which are subject to prevailing economic conditions and to financial, business and other factors, some of which are beyond our control.

      The following table summarizes our contractual obligations, net of estimated sublease income, and including obligations for executed agreements for which we do not yet have the right to control the use of the property at January 30, 2005, and the effect that such obligations are expected to have on our liquidity and cash flows in future periods (in thousands):

      The operating and capital lease commitment payment schedule above is shown net of estimated sublease income. Sublease income for operating and capital leases at January 30, 2005 is as follows (in thousands):

      We issue letters of credit for guarantees provided for insurance programs, capital lease agreements and utilities. As of January 30, 2005, $35.8 million was outstanding under our letters of credit.

      We have an investment in MMI Holdings, Inc., or MMIH, a provider of veterinary and other pet-related services. MMIH, through a wholly owned subsidiary, Medical Management International, Inc., or MMI, operates full-service veterinary hospitals and wellness hospitals inside approximately 430 of our stores, under the registered trademark of Banfield, The Pet Hospital. Philip L. Francis, our Chairman and Chief Executive Officer, and Robert F. Moran, our President and Chief Operating Officer, are members of the board of directors of MMIH. Our investment consists of common and convertible preferred stock. During the second quarter of 2004, we purchased an additional $0.8 million of MMIH capital stock from certain MMIH stockholders, and as of January 30, 2005, we owned approximately 16.5% of the voting stock and approximately 36.1% of the combined voting and non-voting stock of MMIH. We charge MMI licensing fees for the space used by the veterinary hospitals, and we treat this income as a reduction of the retail stores’ occupancy costs. We record occupancy costs as a component of cost of sales in our consolidated statements of operations. Licensing fees are determined by fixed costs per square foot, adjusted for the number of days the hospitals are open and sales volumes achieved. We recognized licensing fees of approximately $13.1 million, $10.5 million and $8.3 million during fiscal 2004, 2003 and 2002 respectively. Licensing fees receivable from MMI totaled $5.4 million and $4.4 million at January 30, 2005 and February 1, 2004, respectively, and were included in receivables in the accompanying consolidated balance sheets.

      At our option, on November 21, 2003, we amended our credit facility to reduce the available commitment to $125.0 million, extend the maturity by two years to April 30, 2008, and amended certain covenants. The credit facility permits us to pay dividends, so long as we are not in default or the payment of dividends would not result in default. The credit facility is secured by substantially all our personal property assets and certain real property. We pay a fee to the lenders each quarter at an annual rate of 0.25% of the unused amount of the credit facility. As of January 30, 2005, we had no borrowings outstanding under the credit facility; however, we issue letters of credit for guarantees provided for insurance programs, capital lease agreements and utilities.

      Our business is subject to seasonal fluctuations. We typically realize a higher portion of our net sales and operating profit during the fourth fiscal quarter. As a result of this seasonality, we believe that quarter-to-quarter comparisons of our operating results are not necessarily meaningful, and that these comparisons cannot be relied upon as indicators of future performance. Controllable expenses, such as advertising, could

fluctuate from quarter-to-quarter in a fiscal year. Sales of certain products and services designed to address pet health needs are seasonal. Because our stores typically draw customers from a large trade area, sales also may be impacted by adverse weather or travel conditions, which are more prevalent during certain seasons of the year. Finally, as a result of our expansion plans, the timing of new store openings and related preopening expenses, the amount of revenue contributed by new and existing stores, and the timing and estimated obligations of store closures, our quarterly results of operations may fluctuate.

      The FASB issued FASB Interpretation, or FIN, 46, “Consolidation of Variable Interest Entities,” an interpretation of Accounting Research Bulletin No. 51, “Consolidated Financial Statements,” on January 17, 2003. FIN 46 requires that an entity holding a majority of the “variable interest” of a “variable interest entity” must consolidate the operations of that variable interest entity of which it is the primary beneficiary. In 2003, we purchased two land parcels from a structured lease financing facility. Subsequent to this purchase and also in 2003, the structured lease financing facility was liquidated. FIN 46 was effective for us on August 4, 2003. With the liquidation of the special purpose entity during 2003, the adoption of FIN 46 did not have a material impact on our consolidated financial statements.

      In March 2003, the FASB’s Emerging Issues Task Force, or EITF, reached a consensus on Issue 02-16, “Accounting by a Customer (including a Reseller) for Cash Consideration Received from a Vendor.” The transition provisions apply prospectively to arrangements with vendors entered into or modified after December 31, 2002, do not allow for prior period reclassification, and require companies to account for all amounts received from vendors as a reduction of the cost of the products purchased unless certain criteria are met that allow companies to account for vendor funding as a reduction of related operating, general and administrative expenses. During 2004, 2003 and 2002, we recorded approximately $10.4 million, $10.9 million and $11.0 million, respectively, for cooperative promotional income. We adopted the provisions of EITF 02-16 for vendor contracts entered into or modified subsequent to December 31, 2002, and the adoption did not have a material impact on the consolidated financial statements.

      In November 2003, the FASB’s Emerging Issues Task Force reached a consensus on Issue 03-10, “Application of Issue No. 02-16 by Resellers to Sales Incentives Offered to Consumers by Manufacturers.” Under EITF 03-10, any cash consideration a company receives from a vendor as part of a certain exclusive sales incentive arrangement must be recorded in the income statement as an offset to cost of sales, and cannot be recorded as revenue, unless the company meets certain criteria. EITF 03-10 is effective for new arrangements and modifications to existing arrangements entered into in fiscal periods beginning after November 25, 2003. EITF 03-10 permits reclassification of prior periods for comparison purposes. We adopted EITF 03-10 on February 2, 2004, which resulted in a decrease in sales and a corresponding decrease in cost of sales in the consolidated statements of operations of $3.3 million and $2.9 million in fiscal 2004 and 2003, respectively.

      On December 16, 2004, the FASB issued FASB Statement No. 123 (revised 2004), “Share-Based Payment” (“SFAS 123(R)”), which is a revision of FASB Statement No. 123 (“SFAS 123”), “Accounting for Stock-Based Compensation” and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and its related implementation guidance. SFAS 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their grant-date fair values. SFAS 123(R) is effective for public companies at the beginning of the first interim or annual period beginning after June 15, 2005. We intend to adopt SFAS 123(R) beginning in our first quarter of fiscal 2005 ending May 1, 2005 and intend to utilize the modified retrospective transition method, which allows the restatement of prior periods by recognizing compensation cost in the amounts previously reported in the pro forma footnote disclosures under the provisions of SFAS 123.

      In July 2004, the EITF reached a consensus on Issue 02-14, “Whether the Equity Method of Accounting Applies When an Investor Does Not Have an Investment in Voting Stock of an Investee But Exercises Significant Influence Through Other Means” (“EITF 02-14”). EITF 02-14 concludes that the equity method of accounting is applicable to investments in common stock and in-substance common stock when the investor

has the ability to exercise significant influence over the operating and financial policies of an investee. EITF 02-14 was applicable in the first reporting period beginning after September 14, 2004. We adopted EITF 02-14 during the fourth quarter of fiscal 2004, and the adoption had no impact on our financial position or results of operations.

      Consistent with Section 10A(i)(2) of the Securities Exchange Act of 1934, as added by Section 202 of the Sarbanes-Oxley Act of 2002, PETsMART is responsible for listing the non-audit services approved in the fourth quarter of fiscal 2004 by the PETsMART Audit Committee to be performed by Deloitte & Touche LLP, our independent registered public accountants. Non-audit services are defined in the law as services other than those provided in connection with an audit or a review of the financial statements of PETsMART. There were no non-audit services approved by the Audit Committee in the fourth quarter of fiscal 2004.

      We are subject to certain market risks arising from transactions in the normal course of our business. Such risk is principally associated with interest rate and foreign exchange fluctuations, as well as changes in our credit standing. In addition, a market risk exists associated with fuel prices.

Interest Rate Risk

      We have the ability to use a revolving line of credit and short-term bank borrowings to support seasonal working capital needs and to finance capital requirements of the business. There were no borrowings during fiscal 2004 or 2003. Borrowings under the revolving line of credit bear interest at the bank’s prime rate plus 0% to 0.50% or LIBOR plus 1.25% to 1.75%, at our option.

Foreign Currency Risk

      Our Canadian subsidiary operates 25 stores and uses the Canadian dollar as the functional currency and the United States dollar as the reporting currency. We have certain exposures to foreign currency risk. However, we believe that such exposure does not present a significant risk due to a relatively limited number of transactions and accounts denominated in foreign currency. Approximately $87.7 million, or 2.6%, of our revenues for fiscal 2004 were denominated in the Canadian dollar. Transaction gains and losses on United States dollar denominated transactions are recorded within operating, general and administrative expenses in the consolidated statements of operations. During the second quarter of 2004, we implemented a new structure in our Canadian subsidiary that we believe will allow us to minimize the impact of future transaction gains and losses. We had net exchange gains approximating $2.4 million in fiscal 2004.

      The information required by this Item is attached as Appendix F.

      Not applicable.

      PETsMART maintains disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure.

      As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended, our management conducted an evaluation (under the supervision and with the participation of our CEO and our CFO) as of the end of the period covered by this report, of the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In performing this evaluation, management reviewed our lease accounting practices. As a result of this review, management concluded that our previously established lease accounting practices were not appropriate under accounting principles generally accepted in the United States of America (“GAAP”).

      Accordingly, as described in Note 2 to the Consolidated Financial Statements, management concluded and recommended and our audit committee approved that restatements of financial statements for prior fiscal years and periods would be required to correct the lease accounting errors. Based on their evaluation, our CEO and CFO concluded that, solely due to our restatement due to lease accounting practices as described above, our disclosure controls and procedures were not effective as of January 30, 2005.

Management’s Report on Internal Control Over Financial Reporting

      We are responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Our internal control system is designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements.

      A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. 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.

      We have assessed the effectiveness of our internal control over financial reporting as of January 30, 2005. Our assessment was based on criteria set forth in Internal Control — Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

      In performing this assessment, we reviewed our lease accounting practices. As a result of this review, we concluded that our controls over the selection, monitoring and review of assumptions and factors affecting lease accounting practices were ineffective as of January 30, 2005 due to errors in our interpretation of GAAP. On March 1, 2005, we determined that it was appropriate to restate certain of our previously issued financial statements to reflect the correction of these errors in our lease accounting. We evaluated the impact of this restatement on our assessment of internal control over financial reporting and concluded that the control deficiencies that resulted in incorrect lease accounting represented a material weakness as of January 30, 2005.

      A material weakness in internal control over financial reporting is a control deficiency (within the meaning of the Public Company Accounting Oversight Board’s (“PCAOB”) Auditing Standard No. 2), or combination of control deficiencies, that results in there being more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. PCAOB Auditing Standard No. 2 identifies a number of circumstances that, because of their likely significant negative effect on internal control over financial reporting, are to be regarded as at least significant deficiencies, as well as strong indicators of a material weakness, including the restatement of previously issued financial statements to reflect the correction of a misstatement. As a result of the material weakness related to our lease accounting, we have concluded that, as of January 30, 2005, our internal control over financial reporting was not effective based on the criteria set forth in the COSO framework. We identified no other material weaknesses in performing our assessment and reaching our conclusion.

      Our independent registered public accounting firm, Deloitte & Touche LLP, has issued an audit report on our assessment of PETsMART’s internal control over financial reporting, which is included herein.

      To remediate the material weakness in PETsMART’s internal control over financial reporting, we have changed our policies and procedures in the first quarter of fiscal 2005 to conform to GAAP, and we are implementing additional review procedures over the selection and monitoring of appropriate assumptions and factors affecting lease accounting practices. No other material weaknesses were identified as a result of our assessment.

      There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) of the Securities Exchange Act of 1934, as amended, that occurred during PETsMART’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. As noted above, during the first quarter of fiscal 2005 we are implementing certain remediation steps to address the identified material weakness which has materially affected our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

PETsMART, Inc.

Phoenix, Arizona

      We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control Over Financial Reporting, that PETsMART, Inc. and subsidiaries (the “Company”) did not maintain effective internal control over financial reporting as of January 30, 2005, because of the effect of the material weakness identified in management’s assessment based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’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. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’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, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

      A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

      A material weakness is a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. The following material weakness has been identified and included in management’s assessment: the Company failed to design and implement appropriate controls related to the accounting for leases in accordance with generally accepted accounting principles. In particular, the Company has not designed and implemented controls to adequately analyze the terms of new leases to properly account for the following items:

      These adjustments resulted in the restatement of the Company’s consolidated financial statements for the fiscal years ended February 1, 2004 and February 2, 2003. Based on the significance of the adjustments identified, there is a more than remote likelihood that a material misstatement of the interim and annual financial statements would not have been prevented or detected.

      This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated financial statements and financial statement schedule as of and for the year ended January 30, 2005, of the Company and this report does not affect our reports on such financial statements and financial statement schedule.

      In our opinion, management’s assessment that the Company did not maintain effective internal control over financial reporting as of January 30, 2005, is fairly stated, in all material respects, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Also in our opinion, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of January 30, 2005, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

      We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended January 30, 2005, of the Company and our reports dated April 11, 2005 expressed an unqualified opinion on those financial statements and financial statement schedule, and included an explanatory paragraph relating to the restatement of the financial statements.

      We have audited the accompanying consolidated balance sheets of PETsMART, Inc. and subsidiaries (the “Company”) as of January 30, 2005 and February 1, 2004, and the related consolidated statements of operations and comprehensive income, stockholders’ equity, and cash flows for each of the three fiscal years in the period ended January 30, 2005. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements 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, such consolidated financial statements present fairly, in all material respects, the financial position of PETsMART, Inc. and subsidiaries as of January 30, 2005 and February 1, 2004, and the results of their operations and their cash flows for each of the three fiscal years in the period ended January 30, 2005 in conformity with accounting principles generally accepted in the United States of America.

      As discussed in Note 2 to the consolidated financial statements, the accompanying consolidated financial statements have been restated.

      We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company’s internal control over financial reporting as of January 30, 2005, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated April 11, 2005 expressed an unqualified opinion on management’s assessment of the effectiveness of the Company’s internal control over financial reporting and an adverse opinion on the effectiveness of the Company’s internal control over financial reporting because of a material weakness.
