Item 1. Business.

In this Annual Report on Form 10-K, unless otherwise indicated or the context otherwise requires, all references to “we,” “our,” “us,” “Leslie’s,” “the Company,” and “our Company” refer to Leslie’s, Inc. and its consolidated subsidiaries.

Our Company

Founded in 1963 by Phil Leslie Jr. in Southern California, the Company today known simply as “Leslie’s” has over six
decades of disruptive retail innovation in the $15 billion U.S. pool and spa care industry. Today, we are the largest and most trusted direct-to-consumer brand in our segment, serving residential consumers and pool professionals, and many of the largest commercial property operators in the country. With over 1,000 retail locations, an integrated, digitally forward omnichannel strategy, and a horizontally integrated, nationwide ecosystem under the Leslie’s and In the Swim® brands, among others, we have built a market-leading share of residential aftermarket product spend, based on 2024 industry analyst reports, and a physical network larger than the sum of our 20 largest competitors. We offer an extensive assortment of professional-grade products, the majority of which are exclusive to Leslie’s, manufacturer certified installation and repair services, and in some markets, weekly pool maintenance services. Our dedicated, knowledgeable team of associates, pool and spa care experts, and experienced service technicians, are passionate about empowering every single Leslie’s customer with the knowledge, products, and solutions necessary to confidently maintain and thoroughly enjoy their pools and spas. The considerable scale of our integrated marketing and distribution ecosystem, which is powered by our direct-to-consumer network, uniquely enables us to efficiently reach and service nearly every pool and spa in the continental United States.

We operate primarily in the pool and spa aftermarket industry, a fundamentally attractive category in retail, given its scale, historical predictability, and growth outlook. More than 85% of our product assortment is comprised of non-discretionary products essential to the care of residential and commercial pools and spas. This includes chemicals, new and replacement parts, cleaning and maintenance equipment, safety, recreational, and fitness-related products. We also offer important essential services, such as equipment installation and repair for residential and commercial customers. We have relationships with professional pool operators from major hotel and apartment owners to municipal, county and state governments, all the way to sole proprietors. In addition to a strong consumer and commercial retail and service presence, we operate a wholesale specialty pool and spa parts distribution business, giving us unique access to hard-to-find specialty parts; an integrated manufacturing plant, giving us vertical scale and competitive cost on parts of our chemical assortment; and a regionally located, hub-and-spoke distribution system throughout the continental United States.

We offer complimentary, commercial-grade in-store water testing and analysis via our proprietary AccuBlue® system, leading to increased consumer engagement, conversion, basket size, and loyalty, resulting in higher lifetime value. Our water treatment expertise is powered by data and intelligence accumulated from the millions of water tests we have performed over the years, positioning us as the most trusted water treatment service provider in the recreational pool and spa industry. We then brought AccuBlue® direct to pool owners’ backyards with AccuBlue Home®, a pioneering app-enabled water testing device. These differentiated capabilities allow us to meet the needs of any pool and spa owner, whether they care for their pool or spa themselves or rely on a professional, whenever, wherever, and however they choose to engage with us.

Our Competitive Strengths

We believe that the following competitive strengths have been key drivers of our success to date, and strategically position us for continued success.

We are the direct-to-consumer market leader in the aftermarket pool and spa care industry, with close proximity to U.S. pool and spa installations.

For over 60 years, we have been dedicated to addressing our consumers’ pool needs so that they can spend less time maintaining and more time enjoying their pools. While we sell many pool and spa services and solutions, we view our ultimate goal as enabling joy with family and friends. We are the only direct-to-consumer pool and spa care brand with a nationwide physical presence and an integrated digital platform, consisting of individually merchandised e-commerce websites, a mobile app with transaction capabilities, and online marketplace operations, designed to address the needs of all pool and spa consumers. Further, our locations are strategically situated within 20 miles of 80% of pools in the country, and in the sunbelt, nearly 90% of pools are within a 15 mile radius of our locations, according to 2024 industry analyst reports. The remainder of the industry is highly fragmented across both offline and online providers, including mass merchant stores with a much narrower assortment of pool and spa care solutions, and local independent operators.

Direct relationships with pool and spa owners and professional service providers, driving strong Company loyalty programs.

We are the largest national pool and spa care brand with a direct relationship with pool and spa owners and importantly, those who serve them. Our database includes over 12 million consumers who have relied on our integrated platform, for their ongoing pool and spa care needs. Through our best-in-class proprietary water testing and backed by our team of highly trained pool and spa experts, we offer sophisticated product recommendations and other expert advice, which cultivates long-standing relationships with our consumers and drives our leading loyalty programs, including Pool Perks®, our retail loyalty program, as well as our PRO Partner loyalty program for service professionals. The comprehensive nature of our product and service offering enables our customers to reap expanded benefits by staying within the Leslie’s ecosystem. Pool Perks®, revamped earlier this year for more rewarding engagement by embracing three different loyalty tiers, specifically drives exceptional retention with a higher per transaction spend versus non-loyalty members. We define “direct relationships” as the number of unique customers for whom we have a mailing address, a phone number, or an email address, and many of which are Pool Perks® members.

Consumer-centric connected ecosystem for all pool and spa owners and the professionals who serve them using proprietary, leading brands across all channels.

We have built the most extensive and geographically diverse pool and spa care network in the United States. Our locations are strategically located in densely populated areas mainly throughout the Sunbelt, including California, Arizona, Texas, and Florida, and have a full omni-channel capability to ship to each state within the United States. Across our physical network, we employ a team of more than 3,700 associates, including pool and spa care experts and service technicians, who act as solution providers to both “do-it-yourself” (“DIY”) and “do-it-for-me” (“DIFM”) pool owners as well as pool professionals.

As digital transactions have become many customers’ default preference, we have focused on architecting an industry-leading integrated digital platform of proprietary e-commerce websites via our Leslie’s and In The Swim® brands and the Leslie’s iOS and Android apps. Our proprietary e-commerce websites serve digital consumers through curated pricing and targeted merchandising strategies. In addition to our owned and operated e-commerce websites, we also offer our products through online marketplaces such as Amazon, eBay, and Walmart. This year, we launched an exciting test partnership with a leading same-day delivery provider for many essential products, which we plan to sustainably expand. As a result of our strategic investments in digital, we are uniquely positioned to serve our consumers with cross-channel capabilities and capture incremental online demand from new consumers while growing the total profitability of the network.

Comprehensive assortment of proprietary brands with recurring, essential, superior product formulations, and trusted, solution-based services for all consumers.

We offer a comprehensive product range, consisting of more than 25,000 products across chemicals, equipment and parts, cleaning and maintenance equipment, safety, recreational, and fitness-related categories. More than 80% of our product sales are non-discretionary and recurring in nature. In addition, more than 55% of our total sales and 82% of our chemical sales are derived from proprietary brands and custom-formulated products, which allows us to create an entrenched consumer relationship, optimize our supply chain, and capture attractive margins. Consumers choose our exclusive, proprietary brands and custom-formulated products for their efficacy and value, a combination that we believe cannot be found elsewhere.

We pair our comprehensive product assortment with differentiated in-store and on-site service offerings. We pioneered the complimentary in-store water test and resulting proprietary water prescription, which has driven consumer traffic and loyalty, and has created a pharmacy-like consultative relationship with our consumers. We further made significant upgrades to our water testing capabilities with the launch of our AccuBlue® platform. Our AccuBlue® water test screens for 10 distinct water quality criteria including pH, total alkalinity, chlorine levels, cyanuric acid, and more, to determine the pool's health and safety. Our in-store experts leverage our proprietary AccuBlue® water diagnostics software engine to offer our consumers a customized prescription and treatment plan using our comprehensive range of exclusive products, walking them step-by-step through the product use sequence. These detailed and sophisticated treatment algorithms are supported by our differentiated, decades-long water treatment expertise. Historically, we have found that consumers who test their water with us regularly spend more with us per year than those who do not, underscoring the importance of this acquisition and retention vehicle. In 2023, we pioneered this same proprietary, commercial grade technology for consumers in the comfort of their own backyards, with AccuBlue Home®. We also employ the industry’s largest network of in-field technicians who perform on-site evaluations, installation, and repair services for residential consumers and professional pool operators.

Highly experienced and visionary leadership team that combines deep industry expertise and advanced direct-to-consumer capabilities.

Our strategic vision and culture are driven by our executive leadership team. Our well-balanced leadership team is comprised of leaders with experience in the pool and spa care industry as well as recent hires who bring new perspectives and capabilities to Leslie’s from a variety of sectors. Our leadership team is firmly committed to executing our strategic vision and, driving increased traffic and conversion; and focused on creating long-term shareholder value.

Our Company Purpose

Our Vision is to be “America’s One Stop for Pool Care”. We do this by putting the customer at the center of everything that we do. At Leslie’s, our goal is to enable joy and elevate everyday moments through clean, safe and beautiful pools.

Our Growth Strategies

We believe we are well positioned to drive sustainable growth and profitability over the long term by executing on the following strategies:

Drive traffic & grow engaged customer base.

We believe we have significant opportunity to acquire new residential consumers and reactivate lapsed residential consumers, which we plan to do by executing on the following strategies:

Increase share of wallet among existing consumers.

We believe we have a significant opportunity to increase spend from existing consumers and drive higher lifetime value. We plan to do this by executing on the following strategies:

Continue our focus on the convenience Leslie’s can offer our customers.

People today are busier than ever before, and today’s consumer thinks in “minutes and hours” well before “days”. In our portfolio some products have the customer availability expectation of mere minutes. They have a ‘need’ and time for them is of the essence. Some areas of focus for this include:

Continue to introduce disruptive innovation.

Leslie’s has a legacy of disruptive innovation in the pool and spa care industry. We plan to continue that legacy by developing and introducing capabilities that create loyalty amongst our customers, provide novel solutions for pool owners, and create value for our shareholders. Present areas of focus include water testing, maintenance prescriptions, new product offerings, and our product distribution ecosystem.

We know consumers will seek the convenience of “smart” home functionality in more facets of their daily lives. We believe there is an opportunity to introduce a full service, connected home solution that effectively automates pool maintenance, including actively monitoring our consumers’ water, diagnosing, developing, and prescribing a treatment plan, and delivering to their home the assortment of products needed to maintain a clear, safe, and beautiful pool.

Accordingly, in fiscal 2023 we completed the commercial launch of our AccuBlue Home® program, a subscription-based offering that enables pool and spa owners to confidently test and treat their pools and spas without ever having to leave their backyard. Using the new, industry-leading AccuBlue Home® connected device combined with the Leslie’s mobile app, program members can utilize commercial grade water testing in the convenience of their own home and can test all critical aspects of their water chemistry with ease, generating a custom treatment plan tailored to the specifications of their pool or spa. Seamlessly within the Leslie’s mobile app, consumers can review their prescription, order the products they need, and have them delivered right to their door or arrange for a same-day pick-up at their local Leslie’s location.

In fiscal 2025, as mentioned above, we launched a trial partnership with an on-demand, same-day delivery platform tailored for Leslie’s customers and pool owners who simply know what they need and know they need it quickly. We completed a redesign of our Pool Perks® loyalty program by offering up loyalty tiers for the first time, which we believe increases engagement with our major customers and entice occasional customers to gain more by spending more.

Our Industry

We operate in the aftermarket pool and spa care industry, which is broadly comprised of: (i) chemicals; (ii) equipment, parts, and accessories; and (iii) services. The United States market consists of millions of installed pools and spas, which require routine maintenance throughout their lifetime. This drives an annuity-like stream of demand for the chemicals and products necessary to properly maintain a pool or spa, and Leslie’s is at the forefront of providing innovative products and solutions for this recurring, necessary share of wallet.

While we benefit from the growth in the installed base, our business is not dependent on new pool construction activity and can generate strong growth from a fixed installed base through increased pool usage, more frequent sanitization, and recurring maintenance needs. Increasing our customer file and growing our loyalty membership should also have a positive effect on our growth from a fixed installed base which is not dependent on new pool construction.

Seasonality

Our business is highly seasonal. Sales and earnings are highest during our third and fourth fiscal quarters, which include April through September, and represent the peak months of swimming pool use. Sales are substantially lower during our first and second fiscal quarters. Despite the seasonal nature of our business, we have a long track record of investing in our business throughout the year, including in operating expenses, working capital, and capital expenditures related to new products, locations, and other growth initiatives. While these investments drive performance during the primary selling season in our third and fourth fiscal quarters, they have a negative impact on our earnings and cash flow during our first and second quarters.

We typically experience a build-up of inventory and accounts payable during the first and second fiscal quarters in anticipation of the peak swimming pool supply selling season. We negotiate extended payment terms with certain of our primary suppliers as we receive merchandise in December through March in advance of the swimming pool supply selling season.

The principal external factor affecting our business is weather. Hot weather can increase purchases of chemicals and other non-discretionary products as well as purchases of discretionary products and can drive increased purchases of installation and repair services. Unreasonably cool weather or significant amounts of rainfall during the peak pool sales season can reduce chemical consumption in pools and spas and decrease consumer purchases of our products and services. In addition, unseasonably early or late warming trends can increase or decrease the length of the pool season and impact time around pool openings and closings, and therefore, our total sales and timing of our sales.

We generally open new locations before our peak selling season begins and close locations after our peak selling season ends. We expect that our quarterly results of operations will fluctuate depending on the timing and amount of sales contributed by new locations.

Our Consumers

We strategically serve all consumers within the aftermarket pool and spa care industry including Residential Pool, Residential Spa, and Professional Pool consumers.

Our Product and Service Offering

We offer a comprehensive assortment of more than 25,000 products across chemicals, equipment and parts, cleaning and maintenance equipment, and safety, recreational, and fitness related products. Historically, approximately 85% of our assortment has been comprised of essential and non-discretionary products that are needed by residential customers and pool professionals to care for pools and spas. The vast majority of our assortment features non-discretionary products that are shelf-stable and generally not prone to either obsolescence or shrinkage, which could occur from changing technology or consumer buying habits. As the trusted one-stop destination for all aftermarket pool and spa needs, we provide an extensive and highly differentiated product offering. We aim to fulfill the needs of our residential and professional consumers with our comprehensive assortment, in-stock inventory, and product selection across a broad range of premium proprietary and third-party brands.

Since our inception in 1963, we have offered a portfolio of owned and exclusive brands. We continue to expand our selection of exclusive offerings through innovation and product development. Our exclusive brands and products account for more than 55% of total sales and 82% of chemical sales. These proprietary brands and custom-formulated products are only available through our integrated platform and offer professional-grade quality to our consumers, while allowing us to achieve higher gross margins relative to sales of third-party products.

In addition to our comprehensive product assortment, we offer critical services, such as complimentary, commercial grade water testing and in-store equipment repair. We also employ a large in-field service network of pool and spa care service professionals who have the expertise to provide essential on-site equipment installation and repair services for residential consumers and professional pool operators throughout the continental United States.

Our Vertically Integrated Model

We operate a vertically integrated supply chain, packaging, and distribution model, which represents a significant competitive advantage.

Our vertically integrated supply chain enables us to produce and package products at our company-operated packaging facilities and third-party contract packaging facilities. Our strategy is to identify, produce, and package high volume items that do not require sophisticated or capital-intensive production or packaging equipment, but allow us to offer our consumers a premium product while offering us a significant cost advantage. We source a variety of raw materials and chemicals directly from a diversified supplier base; and maintain strong relationships with these suppliers. As of October 4, 2025, we had one supplier that represented more than 10% of our annual purchases. Using these raw materials, we manufacture and package a wide selection of final products, including, but not limited to, chlorine products, pH adjusters, and filter cleaners. A significant portion of our total mix is comprised of products that we manufacture or package through vertical integration, which offers economies of scale that have resulted in higher quality products and a structurally advantaged margin profile.

We also operate a vertically integrated distribution and delivery model. In addition to operating two manufacturing facilities, we operate a national network of company-operated distribution centers in addition to utilizing third-party distribution centers. Our

company-operated distribution centers and our third-party logistics partners have the capacity to carry a broad breadth of our products in significant quantities and are capable of replenishing inventory throughout our physical network. From these facilities, we distribute to our physical network through a contracted fleet of tractors and trailers, which helps ensure optimal in-stock levels throughout the year. Our third-party distribution centers are strategically located to complement our company-operated distribution centers and primarily fulfill online orders.

Our Marketing Strategy

We believe there is potential to drive increased share of wallet among our existing consumers through strategic initiatives, such as our loyalty membership program and dynamic promotions.

Due to the replenishment driven nature of our product mix and long-term consumer relationships, we believe that our investments in consumer acquisition marketing generate attractive returns. We know the location of pools and spas throughout the United States, and by leveraging this information, we have the ability to allocate our advertising dollars in a highly targeted manner. Additionally, we have added experienced marketing talent with significant expertise in analytics and performance marketing to grow our consumer file. Through these strategies, we plan to increase brand awareness and continue profitably acquiring new consumers.

Our Competition

The United States aftermarket pool and spa care industry is fragmented and competitive. We compete against a wide range of manufacturers, retailers, distributors, and service providers in the residential and professional pool and spa care market. This includes original equipment manufacturers, regional and local retailers, home improvement retailers, mass-market and club retailers, and specialty e-commerce operators. Key competitive groups include:

Our competitors offer pool care products and services of varied quality and across a wide range of retail price points. We experience greater brick-and-mortar competition in the states with the largest installed pool bases, including California, Texas, Florida, and Arizona. While some of our competitors also market and sell online, there are various challenges to serving consumers in the aftermarket pool and spa care industry via e-commerce. These challenges include regulatory restrictions on shipping hazardous materials, the need for professional installation of equipment at point of delivery, and the need for regular water testing, expert advice, and customized prescriptions and solutions related to the sale of chemicals. In addition, due to the seasonality of the aftermarket pool and spa care industry, several competitors only stock related products during the summer months, and their product assortment tends to be limited to basic offerings.

Human Capital Resources

As of October 4, 2025, we employed approximately 3,790 employees. Of these, approximately 2,990 work within our physical network, 210 work as in-field service technicians, 360 work in our corporate office, and 230 work in our distribution centers.

Our voluntary turnover rate over the past twelve months was 18% for corporate employees, and for all non-corporate roles including field team members, the turnover rate was 23%. In August 2025, we completed our annual employee engagement survey. Our commitment to culture was shown in a 3% increase in active engagement since the last survey. The strength of our leadership team was made evident in an 87% favorable score on our overall leadership effectiveness, which is a compilation of six survey questions regarding the employee’s direct supervisor’s performance. The executive leadership team prioritized the clarity of our strategic plan and delivery of that plan through an all-leadership summit, resulting in 86% of team members reporting that they feel clear on the goals, objectives, and strategy of the Company (2% increase from the prior survey).

Note: None of our employees are covered by collective bargaining agreements.

We employ various trademarks, trade names and service marks, including Leslie’s®, AccuBlue®, AccuBlue Home®, Pool Perks®, and our logo, in our product packaging and advertising our products. We have registered trademarks and trade names for several of our major products on the Principal Register of the United States Patent and Trademark Office.

Risks Related to the Nature of Our Business

Our success depends on our ability to maintain or increase comparable sales, and if we are unable to achieve comparable sales growth, our profitability and performance could be materially adversely impacted.

Our success depends on increasing comparable sales through our merchandising and marketing strategy and on our ability to increase sales and profits. To increase sales and profits, and therefore comparable sales growth, we focus on delivering value and generating consumer excitement by staffing our locations with pool and spa experts, developing compelling products, optimizing inventory management, maintaining strong location conditions, and effectively marketing current products and new product offerings. If these efforts become less successful, we may not be able to maintain or improve the levels of comparable sales that we have experienced in the past, which could adversely impact our profitability; competition and pricing pressures from competitors may also adversely impact our operating margins. Our comparable sales growth could be, and has been in the past, lower than our historical average or our target for many reasons, including general economic conditions, operational performance, price inflation or deflation, competitive price on similar products, high interest rates, recession fears, industry competition, new competitive entrants near our locations, price changes in response to competitive factors, the impact of new locations entering the comparable base, cycling against any year or quarter of above-average sales results, unfavorable weather conditions, supply shortages or other operational disruptions, the number and dollar amount of consumer transactions in our locations, our ability to provide product or service offerings that generate new and repeat visits to our locations, and the level of consumer engagement that we provide in our locations. Opening new locations in our established markets may result in inadvertent oversaturation, temporary or permanent diversion of consumers, and sales from our existing locations to new locations and reduced comparable sales, thus adversely affecting our overall financial performance. These factors may cause our comparable sales results to be materially lower than in recent periods, which could harm our profitability and business.

Past growth may not be indicative of future growth.

Historically, we have experienced sales growth through organic market share gains, new location openings, and acquisitions that have increased our size, scope, and geographic footprint. Our various business strategies and initiatives, including our growth initiatives, are subject to business, economic, and competitive uncertainties and contingencies, many of which are beyond our control. While we contemplate continued growth through internal expansion and acquisitions, we may not be able to:

If we do not manage these factors successfully, our operating results could be adversely affected.

We may not be able to successfully manage our inventory to match consumer demand, which could have a material adverse effect on our business, financial condition, and results of operations.

We base our inventory purchases, in part, on our sales forecasts. If our sales forecasts overestimate consumer demand, we may experience higher inventory levels, which could result in the need to sell products at lower than anticipated prices, leading to decreased profit margins. Conversely, if our sales forecasts underestimate consumer demand, we may have insufficient inventory to meet demand, leading to lost sales, either of which could materially adversely affect our financial performance.

Loss of key members of management or failure to attract, develop, and retain highly qualified personnel could adversely affect our business.

Our future success depends on the continued efforts of the members of our executive leadership team. If one or more of our executives or other key personnel are unable or unwilling to continue in their present positions, or if we are unable to attract and retain high-quality executives or key personnel in the future, our business may be adversely affected.

We consider our employees to be the foundation for our growth and success. As such, our future success depends in large part on our ability to attract, train, retain, and motivate qualified personnel. During the height of our seasonal activities, we hire additional employees, including seasonal and part-time employees who generally are not employed during the off-season. If we are unable to attract and hire additional personnel during these seasons, our operating results could be adversely affected.

Our business is significantly dependent on our ability to meet our labor needs.

In order to maintain and continue expanding our operations, we depend on our ability to attract and retain qualified team members. Competition for non-entry-level personnel, particularly for team members with retail experience, is significant. Additionally, our ability to maintain a consistent level of high-quality customer service in our stores is critical to our success. Many of our store team members are in entry-level positions that historically have high rates of turnover. We may be unable to meet our labor needs and control our costs due to external factors such as the availability of qualified persons in the work forces of the markets in which we operate, which is impacted by factors including competition, unemployment levels, demand for certain labor expertise, prevailing wage rates, and the potential adoption of new or revised employment and labor laws and regulations. If we are unable to locate, attract, or retain qualified personnel, or if costs of labor or other related costs increase significantly, our financial performance could be adversely affected.

We are subject to, and may in the future be subject to, legal or other proceedings that could have a material adverse effect on us.

From time to time, we are a party to legal proceedings, including matters involving personnel and employment issues, personal injury, antitrust claims, intellectual property claims, securities law claims, and other proceedings arising in or outside of the ordinary course of business. We cannot guarantee that the insurance coverage we maintain for the Company and our directors and officers will be available for or adequately cover current or future claims or that we will be able to maintain adequate insurance in the future at rates we consider reasonable. In addition, there are an increasing number of cases being filed against companies generally, including class-action allegations under federal and state wage and hour laws. We estimate our exposure to these legal proceedings and establish reserves for the probable and reasonably estimated liabilities. Assessing and predicting the outcome of these matters involves substantial uncertainties. Although not currently anticipated by management, unexpected outcomes in these legal proceedings or changes in management’s forecast assumptions or predictions could have a material adverse impact on our results of operations.

Disruptions from natural or man-made disasters or extreme weather, public health and safety issues, geopolitical events and security issues, labor or trade disputes, macroeconomic crises, and similar events could have a material adverse effect on our business.

Natural or man-made disasters or extreme weather (including as a result of climate change), public health and safety issues, geopolitical events and conflicts (including terrorist attacks and armed hostilities), labor or trade disputes, macroeconomic crises (including any stemming from adverse developments in the financial services industry), and similar events can lead to uncertainty and have a negative impact on demand for our products, in addition to causing disruptions to our supply chain. Discretionary spending on chemicals, equipment and parts, cleaning and maintenance equipment, and safety, recreational, and fitness-related products, such as ours, is generally adversely affected during times of economic, social, or political uncertainty. For example, recent and potential changes to US trade policies, particularly escalating tariff exchanges with China and other countries, have disrupted supply chains and increased costs, potentially creating unpredictable customer spending patterns and economic uncertainty that could impact consumers’ discretionary spending. The potential for natural or man-made disasters or extreme weather, geopolitical events and conflicts, labor or trade disputes, macroeconomic crises, and similar events could create these types of uncertainties and negatively impact our business for the short- or long-term in ways that cannot presently be predicted.

We operate in a competitive and fragmented industry, subject to regional variations, and where we face competition from online
platforms, mass merchants, and certain of our suppliers.

The aftermarket pool and spa care industry is highly competitive, fragmented and regionally varied. Our success depends on many factors we cannot control, including localized competition, increased penetration from mass merchants and online competitors with greater scale and bargaining power, and even privately held, independent retailers that may be able to sell certain maintenance products at a loss. Further, some third-party suppliers with which the Company has long-standing relationships also sell their goods through other channels, including with some of our competitors. Customers in competitive markets often have significant bargaining power, low switching costs, and access to extensive information about competing offerings, which can increase pressure on pricing, thus producing upstream pressures on our contractual terms with suppliers and our margins. In addition, if key distribution partners, suppliers, or technology platforms favor competing products or restrict or alter access to their channels, the Company’s ability to attract new customers and retain existing customers could be impaired. Regional variations in pool and spa care and the types of products used in these regions requires an intimate knowledge of the local landscape, and changing tastes and preferences cannot always be anticipated.

Risks Related to Our Industry and the Broader Economy

We face competition from manufacturers, retailers, distributors, and service providers in the residential and professional pool and spa care market.

Within our industry, competition is highly fragmented. We compete against a wide range of manufacturers, retailers, distributors, and service providers in the residential and professional pool and spa care market. This includes original equipment manufacturers, regional and local retailers, home improvement retailers, mass-market retailers, and specialty e-commerce operators.

Most of our competition comes from regional and local independent retailers. National home improvement and retailers, such as Home Depot, Lowe’s, and local and regional hardware stores, typically compete with us mainly on a seasonal basis during the spring and summer months, but experience significantly higher foot traffic than our retail locations. We also face competition from mass-market retail competitors, such as Walmart and Costco, who devote shelf space to merchandise and products targeted to our consumers, as well as online mass-market retailers such as Amazon, who devote online categories to merchandise and products targeted to our consumers. Historically, mass-market retailers have generally expanded by adding new stores and product breadth, but their product offerings of pool-related products have remained relatively constant.] If pool and spa owners are attracted by the convenience afforded by any of our competitors, they may be less inclined to purchase products and/or services from us.

In addition, new competitors may emerge as there are no proprietary technologies or other significant barriers to prevent other firms from entering the swimming pool and spa supply retail market in the future. Should store and internet-based mass-market retailers increase their focus on the pool and spa industry, or increase the breadth of their pool, spa, and related product offerings, they may become a more significant competitor for our industry, which could have an adverse impact on our business. We may face additional competitive pressures if large pool supply retailers look to expand their consumer base. Given the density and demand for pool and spa products, some geographic markets that we serve also tend to have a higher concentration of competitors than others, particularly Arizona, California, Florida, and Texas. These states encompass our largest markets and entry of significant new competitors into them could have a substantial impact on our total sales.

The demand for our swimming pool and spa related products and services can be adversely affected by unfavorable economic conditions.

Consumer discretionary spending affects our sales and is impacted by factors outside of our control, including general economic conditions, the residential housing market, unemployment rates and wage levels, high interest rates, high inflation, disposable income levels, consumer confidence, recession fears, and access to credit. In economic downturns, the demand for swimming pool and spa related products and services may decline, often corresponding with declines in discretionary consumer spending, the growth rate of pool-eligible households, and swimming pool construction. A weak economy may also cause consumers to defer discretionary replacement and refurbishment activity. Even in generally favorable economic conditions, severe and/or prolonged downturns in the housing market could have a material adverse impact on our financial performance. Similarly, slow growth in the number of pool-eligible households can have a lasting negative impact by limiting the potential for future growth of the pool and spa maintenance market.

We believe that homeowners’ access to consumer credit is a critical factor enabling the purchase of new pools, spas and related products. Unfavorable economic conditions and downturns in the housing market can result in significant tightening of credit markets, which limit the ability of consumers to access financing for new swimming pools, spas, and related supplies, and consequently, replacement, repair, and maintenance of equipment. Tightening consumer credit could prevent consumers from obtaining financing for pool and spa projects, which could negatively impact our sales of products and services.

Adverse developments in the housing industry could slow the install of new pools and spas and thus impact demand for our products.

We could be materially impacted if the pace of new home construction fails to keep up with historical trends, population growth, and aggregate demand, particularly if homes change in design to omit features like pools and spas. In addition, as the U.S. housing market has shifted in some regions towards smaller lot sizes and higher-density developments, there is a possibility that new home construction will omit pools and spas altogether or replace individually owned pools and spas with community features. These developments could, in the aggregate, be materially adverse to our growth prospects in future years by reducing the demand for our products.

The demand for pool chemicals may be affected by consumer attitudes towards products for environmental or safety reasons.

We could be adversely affected if consumers lose confidence in the safety and quality of our products. The demand for the pool chemicals sold by us may also be affected by changes in consumer attitudes toward pool chemical products for environmental or safety reasons. To the extent more environmentally friendly alternative pool and spa water treatment methods emerge, we may not be successful in adopting them in a timely manner.

Our results of operations can fluctuate from quarter to quarter for many reasons, including seasonality.

Our sales are highly seasonal and we experience fluctuations in quarterly results as a result of many factors, many of which are outside of our control and/or difficult to predict. We have historically generated a greater percentage of our revenues during the warm weather months of April through September. Timing of consumer purchases will vary each year and sales can be expected to shift from one period to another. As a result, management believes that period-to-period comparisons of results of operations are not necessarily meaningful and should not be relied upon as any indication of future performance or results. In addition, because our revenues are concentrated to a limited number of months, our business is more susceptible to adverse events occurring in those months than other businesses that have consistent levels of revenue throughout the year.

Adverse developments affecting the financial services industry, such as actual events or concerns involving prevailing interest rates, liquidity, defaults, or non-performance by financial institutions or transactional counterparties, could adversely affect our current and projected business operations and our financial condition and results of operations.

Actual events involving reduced or limited liquidity, defaults, non-performance, or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems. Investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Increased interest rates impact the Company and our consumers by making new borrowings or refinancings of our indebtedness obligations more expensive and, for consumers, reducing their access to favorable credit can slow new pool construction and thus reduce demand for our equipment and aftermarket care products. Any decline in available funding or access to our cash and liquidity resources could, among other risks, adversely impact our ability to meet our operating expenses, financial obligations or fulfill our other obligations, or result in breaches of our financial and/or contractual obligations. Any of these impacts, or any other impacts resulting from the factors described above or other similar factors, could have material adverse impacts on our liquidity and our current and/or projected business operations and financial condition and results of operations.

We maintain our cash at financial institutions in balances that may exceed federally insured limits.

The majority of our cash is held in accounts at U.S. banking institutions, and the amounts of cash held in non-interest-bearing and interest-bearing operating accounts may exceed the FDIC insurance limits. If the banking institutions we use were to fail, we could lose all or a portion of those amounts held in excess of such insurance limitations, and our ability to access such funds in a timely manner, or at all, could be limited. Any material loss or delayed receipt of cash that we may experience in the future could have an adverse effect on our ability to pay our operational expenses or make other payments and may require us to move our accounts to other banks, which could cause a temporary delay in making payments to our suppliers, vendors, and employees, and cause other operational challenges.

We are susceptible to adverse weather conditions.

Given the nature of our business, weather is one of the principal external factors affecting our business. Unseasonably cool weather or significant amounts of rainfall during the peak sales season have in the past and can in the future reduce chemical consumption in pools and spas and decrease consumer purchases of our products and services. In addition, unseasonably early or late warming trends have in the past and can in the future increase or decrease the length of the pool season and impact timing around pool openings and closings and, therefore, our total sales and timing of our sales. While warmer weather conditions favorably impact our sales, global warming trends and other significant climate changes can create more variability in the short-term or lead to other unfavorable weather conditions that could adversely impact our sales or operations and could make our operations, seasonality and sales cycles less predictable than in previous years. Drought conditions or water management initiatives sometimes lead to municipal ordinances related to water use restrictions. To the extent such restrictions result in decreased pool installations, our sales could be negatively impacted.

Certain extreme weather events, such as hurricanes and tropical storms, may become more frequent, and when such events occur, they can impact demand for our products and services, our ability to deliver our products, provide services, continue to keep our facilities open and operational, cause damage to our facilities, or impact our business in other ways. As a consequence of these or other catastrophic or uncharacteristic events, we may experience interruption to our operations, increased costs or loss of property, equipment or inventory, which would adversely affect our revenue and profitability.

Technology and Privacy Related Risks

If the technology-based systems that give our consumers the ability to shop with us online do not function effectively, our operating results, as well as our ability to grow our e-commerce business globally, could be materially adversely affected.

Many of our consumers shop with us through our physical network and digital platform, which includes our proprietary mobile app and e-commerce websites. Increasingly, consumers are using tablets and smart phones to shop online with us and with our competitors and to do comparison shopping. We are increasingly using social media and our proprietary mobile app to interact with our consumers and as a means to enhance their shopping experience. Any failure on our part to provide an attractive, effective, reliable, and user-friendly digital platform that offers a wide assortment of merchandise with rapid delivery options and that meets the changing expectations of online shoppers could place us at a competitive disadvantage, result in the loss of e-commerce and other sales, harm our reputation with consumers, have a material adverse impact on the growth of our e-commerce business globally, and could have a material adverse impact on our business and results of operations.

Our e-commerce operation faces distinct risks, such as the failure to make and implement changes to our e-commerce websites and mobile app, the failure to maintain a relevant consumer experience in understanding and interacting with our e-commerce websites and mobile app, telecommunications disruptions, reliance on third-party software technologies, and rapid changes in technology, among others. If not managed effectively, these risks could adversely impact our operating results.

A significant portion of our digital sales take place through online marketplaces and online retailers and any limitation or restriction, temporarily or otherwise, to sell on these online platforms could harm our profitability and results of operation.

Marketplace storefronts complement our platform of branded proprietary e-commerce websites. A significant portion of our digital sales take place through online marketplaces and online retailers and are subject to their terms of service and their various other policies including fees charged for transacting on the corresponding platforms. While we endeavor to materially comply with the terms of service and other policies of each online marketplace and online retailer through which we sell our products, these online marketplaces or online retailers may not have the same determination with respect to our compliance. These online marketplaces and online retailers may, in certain circumstances, refuse to continue hosting us or selling our products or temporarily suspend or discontinue our access to their online platform and any limitation or restriction (whether temporary or otherwise) on our ability to sell our products or a material change in transaction fees charged through these online platforms could harm our profitability and results of operations.

We rely on information technology systems to support our business operations. A significant disturbance or breach of our technological infrastructure could adversely affect our financial condition and results of operations. Additionally, failure to maintain the security of confidential information could damage our reputation and expose us to litigation.

Information technology supports several aspects of our business, including, among others, product sourcing, pricing, consumer service, transaction processing, financial reporting, collections, and cost management. Our ability to operate effectively on a day-to-day basis and accurately report our results depends on robust technological infrastructure, which may be susceptible to internal and external threats. We are vulnerable to interruption by fire, natural disaster, power loss, telecommunication failures, internet failures, security breaches, catastrophic events, and other significant disruptions. Exposure to various types of cyberattacks such as malware, computer viruses, worms, social engineering attacks, or other malicious acts, as well as human error and technological malfunction, could also potentially disrupt our operations or result in a significant interruption in the delivery of our goods and services.

We also may experience occasional system interruptions and delays, as a result of routine maintenance, periodic updates, or other factors, that make our information systems unavailable or slow to respond, including the interaction of our information systems with those of third parties. A lack of sophistication or reliability of our information systems could adversely impact our operations and consumer service and could require major repairs or replacements, resulting in significant costs and foregone revenue.

Our numerous procedures and protocols designed to mitigate cybersecurity risks (including processes for timely notification of appropriate personnel, for assessment and resolution of cybersecurity incidents, and for company-wide training programs, our investments in information technology security and our updates to our business continuity plan) may not prevent or effectively mitigate adverse consequences from cybersecurity risks. Any failure by us to maintain or protect our information technology systems and data integrity, including from cyberattacks, intrusions, or other breaches, could result in unauthorized access to consumer data, credit card information, and personally identifiable information, theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information and disrupt our operations, putting us at a competitive disadvantage. Such a breach could result in damage to our reputation and subject us to potential litigation, liability, fines, and penalties, resulting in a material adverse impact on our financial condition and results of operations.

Improper activities by third parties, exploitation of encryption technology, new data-hacking tools and discoveries, and other events or developments may result in future intrusions into or compromise of our networks, payment card terminals, or other payment systems.

We may not be able to anticipate the frequently changing techniques used to obtain unauthorized access to sensitive data or implement adequate preventive measures for all of them. Any unauthorized access into our consumers’ sensitive information, or data belonging to us or our suppliers, even if we are compliant with industry security standards, could put us at a competitive disadvantage, result in deterioration of our consumers’ confidence in us, and subject us to potential litigation, liability, fines, penalties, and consent decrees, resulting in a possible material adverse impact on our financial condition and results of operations.

As a merchant that accepts debit and credit cards for payment, we are subject to the Payment Card Industry Data Security Standard (“PCI DSS”) issued by the Payment Card Industry Council and to the American National Standards Institute (“ANSI”) data encryption standards and payment network security operating guidelines, as well as the Fair and Accurate Credit Transactions Act (“FACTA”). Failure to comply with these guidelines or standards may result in the imposition of financial penalties or the allocation by debit and

credit card companies of the costs of fraudulent charges to us. Despite our efforts to comply with these or other payment card standards and other information security measures, we cannot be certain that all of our IT systems will be able to prevent, contain, or detect all cyberattacks or intrusions from known malware or malware that may be developed in the future. To the extent that any disruption results in the loss, damage, or misappropriation of information, we may be adversely affected by claims from consumers, financial institutions, regulatory authorities, payment card associations, and others. In addition, privacy and information security laws and standards continue to evolve and could expose us to further regulatory burdens. The cost of our continued compliance with stricter laws and standards, including, among other regulations, PCI DSS, ANSI, and FACTA data encryption standards and the California Consumer Privacy Act, which took effect in January 2020, and the California Privacy Rights Act, which took effect on January 1, 2023, and the cost of complying with other state data privacy regulations that we may be subject to in the future, could be significant.

Risks Related to Our Business Strategy

We may acquire other companies or technologies, which could fail to result in a commercial product or sales, divert our management’s attention, result in additional dilution to our stockholders, and otherwise disrupt our business.

We may in the future seek to acquire or invest in businesses or technologies that we believe could complement or expand our portfolio, enhance our technical capabilities, or otherwise offer growth opportunities. We may not be able to successfully complete any acquisition we choose to pursue and we may not be able to successfully integrate any acquired business, product or technology in a cost-effective and non-disruptive manner. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various costs and expenses in identifying, investigating, and pursuing suitable acquisitions, whether or not they are consummated. We may not be able to identify desirable acquisition targets or be successful in entering into an agreement with any particular target or obtain the expected benefits of any acquisition or investment. Similarly, we may not be able to successfully identify and acquire new technologies in a timely manner or at all. Acquisitions could also result in dilutive issuances of equity securities, the use of our available cash, or the incurrence of debt, which could harm our operating results. In addition, if an acquired business fails to meet our expectations, our business, financial condition, and results of operations may be negatively affected.

Changing consumer preferences and demographic shifts could materially impact the demand for pool and spa care products sold via our retail networks.

The Company’s retail and omnichannel strategy is highly dependent on demand from a mix of both DIY and DIFM customers, as well as commercial service professionals. While our growth strategy takes into account potential changes in this mix, our physical retail locations are primarily designed to cater to DIY pool and spa owners. As younger families become homeowners in greater numbers, there is the potential for their aftermarket care needs to shift from DIY to more heavily favor DIFM, meaning our physical store footprint and retail pricing strategy may become out of sync with a changing marketplace.

Our operating results will be harmed if we are unable to effectively manage and sustain our future growth or scale our operations.

We experienced a decline in sales, and thus profitability, beginning the fiscal years ending September 30, 2023, through the fiscal year ending October 4, 2025. The current declines in our revenue and operating margins means our revenue and margin growth may be less than expected. If we are unable to scale our operations efficiently or maintain pricing power and competitive pricing, we may fail to achieve expected operating margins, which would have a material and adverse effect on our operating results. Diminished growth may also stress our ability to adequately manage our operations, quality of products, safety, and regulatory compliance. If growth significantly decreases, it could negatively impact our cash reserves, and it may be necessary to obtain additional financing, which could increase indebtedness or result in dilution to shareholders. Further, we may not be able to obtain additional financing on acceptable terms, if at all.

If we are unable to streamline our operations effectively, our business, financial condition and results of operations may be adversely affected.

Our locations may not achieve the growth and profitability we anticipate, and, from time to time, we may determine to close certain locations based on a variety of factors, including, but not limited to, geographic proximity to other stores, operating cost increases, labor costs, profitability, leases and other strategic decisions. Our business strategy depends in part on our ability to streamline our operations and improve long-term profitability, including the effective implementation of our announced closure of approximately 80 to 90 underperforming U.S. locations by the end of the first fiscal quarter of 2026. Our ability to successfully close those locations, or other future locations as appropriate to operate efficiently, depends on a number of factors beyond our control, including without limitation, general economic conditions, prevailing conditions in the commercial real estate market, success in amending or terminating existing leases on acceptable terms, availability of suitable alternative locations and other factors. If we are unable to optimize our location base by closing the number of underperforming locations we expect, on the timeline we expect, or if we are unable to transfer these existing

store customers to our other sales channels or if we announce additional store closures in the future, our business, financial condition and results of operations may be adversely affected.

In addition, we expect to incur costs associated with the closure of underperforming locations, including charges for the impairment of long-lived assets and inventory write-offs. These costs may turn out to be greater than we expect and may adversely impact our financial condition.

Our aspirations and disclosures related to sustainability matters expose us to risks that could adversely affect our reputation and performance.

We have established and publicly announced various sustainability goals. These statements reflect our current plans and aspirations and do not guarantee that we will be able to achieve them.

Our ability to achieve any sustainability objective is subject to numerous risks, many of which are outside of our control. Additionally, standards for tracking and reporting sustainability matters continue to evolve and vary. Our selection of voluntary disclosure frameworks and standards, and the interpretation or application of those frameworks and standards, may change from time -to-time or differ from those of others. This may result in a lack of consistent or meaningful comparative data from period to period or between us and other companies in the same industry.

In addition, our processes and controls may not comply with evolving standards for identifying, measuring, and reporting sustainability metrics, including sustainability -related disclosures that may be required of companies by U.S. federal or state governments and other regulators, and such standards may change over time, which could result in significant revisions to our existing processes and controls, reporting, and current goals, reported progress in achieving such goals, or ability to achieve such goals in the future.

Our sustainability practices may not satisfy all investor or other stakeholder expectations and standards, which are evolving and varied and may not align with our sustainability strategy. As a result, our reputation, our ability to attract or retain employees, and our attractiveness as an investment or partner could be negatively impacted. Further, our success, failure or perceived failure to pursue, track report or fulfill our goals and objectives or to satisfy various reporting standards on a timely basis, or at all, could adversely affect our reputation, financial performance, and growth, and expose us to increased scrutiny, review, or litigation from our stakeholders, including the investment community, media outlets (including social media) and enforcement authorities.

Risks Related to the Manufacturing, Processing, and Supply of Our Products

Our business includes the packaging and storage of chemicals and an accident related to these chemicals could subject us to liability and increased costs.

We operate chemical repackaging and manufacturing facilities and we store chemicals in our locations and in our distribution facilities. Because some of the chemicals we repackage, manufacture and store are hazardous materials, we must comply with various fire and safety ordinances. However, a release at a location or a fire at one of our facilities could give rise to liability claims against us and potential environmental liability. In addition, if an incident involves a repackaging, manufacturing or distribution facility, we might be required temporarily to use alternate sources of supply that could increase our cost of sales.

We cannot guarantee that our insurance coverage will be adequate to cover future claims that may arise or that we will be able to maintain adequate insurance in the future at rates we consider reasonable. Successful claims for which we are not fully insured may adversely affect our working capital and profitability. In addition, changes in the insurance industry have generally led to higher insurance costs and decreased availability of coverage.

Notwithstanding our internal training curriculum and compliance programs, we cannot guarantee that our employees will follow the applicable operating procedures and regulations, or that no accidents or incidents will arise that could expose us to liability and have a negative impact on our operations and results.

Product supply disruptions may have an adverse effect on our profitability and operating results.

We rely on various suppliers and vendors to provide and deliver product inventory on a continuous basis, some of which are located outside of the United States. These suppliers (and those they depend upon for materials and services) are subject to risks, including from natural or man-made disasters or extreme weather (including as a result of climate change), public health and safety issues, geopolitical events and conflicts (including terrorist attacks and armed hostilities), power outages, labor or trade disputes, union organizing activities, disruption to transportation routes, changes in tariffs or duties imposed on imported products or raw materials, financial liquidity

problems, and similar events, as well as supply constraints and general economic, social, and political conditions that can limit their ability to provide us (or our suppliers) with quality products and services in a timely manner and at reasonable cost. The occurrence of these or other unexpected events can cause us to suffer significant product inventory losses, and significant lost revenue, and increased cost of sales. For example, recent and potential changes to U.S. trade policies, particularly escalating tariff exchanges with China and other countries, have disrupted supply chains and increased costs, potentially creating unpredictable customer spending patterns and economic uncertainty that could, directly or indirectly, significantly impact business operations, financial conditions, and results in ways difficult to anticipate or mitigate.

The cost of raw materials could increase our cost of goods sold and cause our results of operations and financial condition to suffer.

Our principal chemical raw materials are granular chlorine compounds, which are commodity materials. The prices of granular chlorine compounds are a function of, among other things, manufacturing capacity and demand. In the past, we have generally been able to pass along chlorine price increases to our consumers. However should the price of granular chlorine compounds increase in the future, we may not be able to pass on any such increase to our consumers. We purchase granular chlorine compounds primarily from the nation’s largest suppliers. The alternate sources of supply we currently view as reliable may ultimately be unable to supply us with all of our raw materials and finished goods, including chlorine products. Additionally, significant price fluctuations or shortages in raw materials needed for our products have increased our cost of goods sold for certain products and may cause our results of operations and financial condition to suffer. For example, during times of highly unstable supply of granular chlorine compounds we believe some customers stockpile chemicals, resulting in unexpected changes in demand. As a result of such behavior, our revenue is higher than normal during periods of stockpiling and lower than normal during the period after stockpiling has occurred. We believe that consumer stockpiling of chemicals may have negatively impacted our results of operations in fiscal 2023 and may impact us in future periods.

Risks Related to Commercialization of Our Products

Even if we are able to attain significant market acceptance of our planned or future products or services, the commercial success of our planned or future products is not guaranteed.

Our future financial success will depend substantially on our ability to effectively and profitably market and sell our planned and future products and services on a sustained basis, which ability is dependent on a number of additional and/or unpredictable factors. Successful growth of our sales and marketing efforts will depend on the strength of our marketing infrastructure and the effectiveness of our sales and marketing strategies, as well as our ability to forecast demand. Our ability to satisfy product demand driven by our sales and marketing efforts will be largely dependent on the ability to maintain a commercially viable manufacturing process that is compliant with regulatory standards. If we fail to market and sell our planned or future products or services successfully, we will not be able to achieve profitability, which could have a material adverse effect on our business, financial condition, and results of operations.

We may implement a product recall or voluntary market withdrawal, which could significantly increase our costs, damage our reputation, and disrupt our business.

The manufacturing, packaging, marketing, and processing of our products involves an inherent risk that our processes do not meet applicable quality standards and requirements. In that event, we may voluntarily implement a recall or market withdrawal or may be required to do so by a regulatory authority. A recall or market withdrawal of one of our products would be costly and would divert management resources. A recall or withdrawal of one of our products, or a similar product processed by another entity, also could impair sales of our products because of confusion concerning the scope of the recall or withdrawal, or because of the damage to our reputation for quality and safety.

If we do not manage product inventory in an effective and efficient manner, it could adversely affect profitability.

Many factors affect the efficient use and planning of product inventory, such as effectiveness of predicting demand, preparing manufacturing to meet demand, meeting product mix and product demand requirements, and managing product expiration. We have in the past and may in the future be unable to manage our inventory efficiently, keep inventory within expected budget goals, keep our work-in-process inventory on hand or manage it efficiently, control expired product, or keep sufficient product on hand to meet demand. We may not be able to keep inventory costs within our target levels. Failure to do so can harm our profitability and long-term growth prospects.

Any significant interruption to the operations of our distribution centers could affect our ability to distribute our products in a timely manner, which could adversely impact our business and financial condition.

We utilize a national network consisting of a mix of company-operated distribution centers as well as third-party operated distribution centers to manage the receipt, storage, sorting, packing and distribution of our merchandise to appropriate stores or to customers directly. We depend in large part on the orderly operation of our receiving and distribution process, which depends, in turn, on adherence to shipping schedules, proper functioning of our information technology and inventory control systems and, the overall effective management of such distribution centers. Work stoppages, labor shortages, operations below historical efficiency levels, supply chain disruptions, inclement weather, or other unforeseen events in the areas or regions in which these distribution centers operate could impair our ability to adequately stock our stores, ship products to our e-commerce customers, process returns of products, and may adversely affect our sales and profitability.

If we do not continue to obtain favorable purchase terms with manufacturers, it could adversely affect our operating results.

Most of the raw materials that go into our products, and products not repackaged by us, are purchased directly from manufacturers. It is common in the swimming pool supply industry for certain manufacturers to offer extended payment terms on certain products to volume purchasers like us. These payment terms typically include favorable pricing and are available to us for pre-season or early season purchases so that we are able to meet anticipated demand each year. However, if we do not continue to maintain such favorable purchase terms with manufacturers, it could adversely affect our operating results.

We depend on a network of suppliers to source our products, including our own branded products. Product quality, warranty claims, or safety concerns could negatively impact our sales and expose us to litigation.

We rely on manufacturers and other suppliers to provide us with the products we sell. As we increase the number of branded products we sell, our exposure to potential liability claims may increase. Product and service quality issues could negatively impact consumer confidence in our brands and our business. If our product and service offerings do not meet applicable safety standards or our consumers’ expectations regarding safety or quality, we could experience lost sales and increased costs and be exposed to legal, financial, and reputational risks, as well as governmental enforcement actions. Actual, potential, or perceived product safety concerns, including health-related concerns, could expose us to litigation, as well as government enforcement actions, and result in costly product recalls and other liabilities.

In addition, if our products are defectively designed, manufactured, or labeled, contain defective components or are misused, we may become subject to costly litigation initiated by consumers. Product liability claims could harm our reputation, divert management’s attention from our core business, be expensive to defend, and may result in sizable damage awards against us. Although we maintain product liability insurance, we may not have sufficient insurance coverage for future product liability claims. We may not be able to obtain insurance in amounts or scope sufficient to provide us with adequate coverage against all potential liabilities. Any product liability claims brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing continuing coverage, harm our reputation, significantly increase our expenses, and reduce product sales. Product liability claims could cause us to incur significant legal fees and deductibles and claims in excess of our insurance coverage would be paid out of cash reserves, harming our financial condition and operating results. In addition, successful product liability claims made against one of our competitors could cause claims to be made against us or expose us to a perception that we are vulnerable to similar claims. Claims against us, regardless of their merit or potential outcome, may also hurt our ability to obtain acceptance of our products or to expand our business.

Risks Related to Government Regulation

The nature of our business subjects us to compliance with employment, environmental, health, transportation, safety, and other governmental regulations.

We are subject to federal, state, and local laws and regulations relating to matters such as product labeling, weights and measures, zoning, land use, environmental protection, local fire codes, and workplace safety, including regulation by the Environmental Protection Agency, the Consumer Product Safety Commission, the Department of Transportation, the Occupational Safety and Health Administration, and the National Fire Protection Agency and corresponding state and local authorities. Most of these requirements govern the packaging, labeling, handling, transportation, storage, disposal, and sale of chemicals. We store certain types of chemicals at each of our locations and the storage of these items is strictly regulated by local fire codes. In addition, we sell algaecides and related products that are regulated under the Federal Insecticide, Fungicide and Rodenticide Act, and various state pesticide laws. These laws primarily relate to labeling, annual registration, and licensing.

Compliance with new and proposed sustainability disclosure requirements, including on the U.S. federal or state level, could require significant effort and divert management’s attention and resources, which could adversely affect our operating results. We are also subject to evolving data privacy and cybersecurity laws and regulations (including applicable standards), compliance with which may also increase our costs of doing business.

Management has processes in place to facilitate and support our compliance with these requirements. However, failure to comply with these laws and regulations, which have become increasingly varied in different regions in which we operate, may result in investigations, the assessment of administrative, civil and criminal fines, damages, seizures, disgorgements, penalties, or the imposition of injunctive relief. Moreover, compliance with such laws and regulations in the future could prove to be costly. Although we presently do not expect to incur any material capital or other expenditures relating to regulatory matters we may be required to make such expenditures in the future. These laws and regulations have changed substantially and rapidly in recent years, and we anticipate that there will be continuing changes.

There has been a general trend in environmental, health, transportation, and safety regulations to place more restrictions and limitations on activities that impact the environment, such as the use and handling of chemicals. Increasingly, strict restrictions and limitations have resulted in higher operating costs for us and it is possible that the costs of compliance with such laws and regulations will continue to increase. Our attempts to anticipate future regulatory requirements that might be imposed and our plans to remain in compliance with changing regulations and to minimize the costs of such compliance may not be as effective as we anticipate.

Risks Related to Intellectual Property Matters

If we are unable to adequately protect our intellectual property rights, our competitive position could be harmed, we may not be able to build name recognition in our markets of interest, or we could be required to incur significant expenses to enforce or defend our rights.

In the course of our business, we employ various trademarks, trade names, and service marks as well as our logo in packaging and advertising of our products. Our commercial success depends in part on our success in obtaining and maintaining issued trademarks, trade names, and service marks in the United States and protecting our proprietary technology. If we do not adequately protect our intellectual property and proprietary technology, competitors may be able to use our technologies or the goodwill we have acquired in the marketplace and erode or negate any competitive advantage we may have, which could harm our business and ability to achieve profitability.

Our ability to enforce our intellectual property rights depends on our ability to detect infringement. It may be difficult to detect infringers who do not advertise the components that are used in their products. Moreover, it may be difficult or impossible to obtain evidence of infringement in a competitor’s or potential competitor’s product. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded if we were to prevail may not be commercially meaningful.

If our trademarks and trade names are not adequately protected, we may not be able to build name recognition in our target markets and our business may be adversely affected. At times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity, possibly leading to market confusion and potentially requiring us to pursue legal action. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our unregistered trademarks or trade names. If we are unable to successfully register our trademarks and trade names and establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights related to trademarks, domain names, copyrights, or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and could adversely impact our financial condition or results of operations.

Our success depends in part on our ability to operate without infringing on or misappropriating the proprietary rights of others, and if we are unable to do so we may be liable for damages.

We cannot be certain that United States or foreign patents or patent applications of other companies do not exist or will not be issued that would prevent us from commercializing our products. Third parties may sue us for infringing or misappropriating their patent or other intellectual property rights. Intellectual property litigation is costly. If we do not prevail in litigation, in addition to any damages we might have to pay, we could be required to cease the infringing activity or obtain a license requiring us to make royalty payments. It is possible that a required license may not be available to us on commercially acceptable terms, if at all. In addition, a required license may be non-exclusive, and therefore our competitors may have access to the same technology licensed to us. If we fail to obtain a required license or are unable to design around another company’s patent, we may be unable to make use of some of the affected products, which would reduce our revenues.

The defense costs and settlements for patent infringement lawsuits are not covered by insurance. Patent infringement lawsuits can take years to settle. If we are not successful in our defense of or are not successful in obtaining dismissals of any such lawsuit, legal fees or settlement costs could have a material adverse effect on our results of operations and financial position.

Risks Related to Our Indebtedness

Our substantial indebtedness could materially adversely affect our financial condition and our ability to operate our business, react to changes in the economy or industry or pay our debts and meet our obligations under our debt agreements, and could divert our cash flow from operations to debt payments.

We have a substantial amount of indebtedness. As of December 5, 2025, our total borrowings under our Amended and Restated Term Loan Credit Agreement (the “Term Loan”) and our $250.0 million credit facility (the “Revolving Credit Facility” and together with the Term Loan, the “Credit Facilities”) was $756.7 million. Subject to restrictions in the agreements governing our debt, it is possible that we may incur additional debt.

Our substantial debt could have important consequences to our stockholders, including but not limited to the following:

Our credit rating was recently downgraded, and there is a risk of further downgrades in the future. Credit rating downgrades have and may continue to adversely affect our ability to access capital markets, increase our borrowing costs, limit our financing options, and reduce our financial flexibility. Lower credit ratings may also result in more stringent covenants in our debt agreements, require us to provide additional collateral for existing obligations, trigger early repayment obligations under certain of our debt instruments, or limit our ability to refinance existing debt on favorable terms. Given our substantial indebtedness, these impacts could further constrain our operational flexibility, intensify the risks associated with our leverage, exacerbate our vulnerability to economic downturns, and adversely affect our liquidity, financial condition, and ability to fund operations, capital expenditures, and strategic initiatives.

Furthermore, all of our debt under our Credit Facilities bears interest at variable rates. If these rates were to increase significantly, our ability to borrow additional funds may be reduced and the risks related to our substantial debt would intensify.

Servicing our debt requires a significant amount of cash. Our ability to generate sufficient cash depends on numerous factors beyond our control, and we may be unable to generate sufficient cash flow to service our debt obligations.

Our business may not generate sufficient cash flow from operating activities to service our debt obligations. Our ability to make payments on and to refinance our debt and to fund planned capital expenditures depends on our ability to generate cash in the future. To some extent, this is subject to general economic, financial, competitive, legislative, regulatory, and other factors that are beyond our control.

If we are unable to generate sufficient cash flow from operations to service our debt and meet our other commitments, we may need to refinance all or a portion of our debt, sell material assets or operations, delay capital expenditures, or raise additional debt or equity capital. We may not be able to effect any of these actions on a timely basis, on commercially reasonable terms or at all, and these actions may not be sufficient to meet our capital requirements. In addition, the terms of our existing or future debt agreements may restrict us from pursuing any of these alternatives.

Restrictive covenants in the agreements governing our Credit Facilities may restrict our ability to pursue our business strategies, and failure to comply with any of these restrictions could result in acceleration of our debt.

The operating and financial restrictions and covenants in the agreements governing our Credit Facilities may materially adversely affect our ability to finance future operations or capital needs or to engage in other business activities. Such agreements limit our ability, among other things, to:

A breach of any of these covenants could result in an event of default under our Credit Facilities. Upon the occurrence of an event of default under any of our Credit Facilities, the lenders could elect to declare all amounts outstanding under our Credit Facilities to be immediately due and payable and terminate all commitments to extend further credit. If we were unable to repay those amounts, the lenders under our Credit Facilities could proceed against the collateral granted to them to secure the debt under the Credit Facilities. We have pledged substantially all of our assets as collateral to secure our Credit Facilities. Our future operating results may not be sufficient to enable compliance with our Credit Facilities, and we may not have sufficient assets to repay amounts outstanding under our Credit Facilities. In addition, in the event of an acceleration of our debt upon an event of default, we may not have or be able to obtain sufficient funds to make any accelerated payments.

Furthermore, the terms of any future debt we may incur could have further additional restrictive covenants. We may not be able to maintain compliance with these covenants in the future, and in the event that we are not able to maintain compliance, we cannot assure you that we will be able to obtain waivers from the lenders or amend the covenants.

Despite current debt levels, we and our subsidiaries may still be able to incur substantially more debt. This could further exacerbate the risks associated with our substantial leverage.

We and our subsidiaries may be able to incur substantial additional debt in the future. Although the agreements governing our Credit Facilities contain restrictions on the incurrence of additional debt, these restrictions are subject to a number of qualifications and exceptions, and the debt incurred in compliance with these restrictions could be substantial. Additionally, we may successfully obtain waivers of these restrictions. If we incur additional debt above the levels currently in effect, the risks associated with our leverage, including those described above, would increase.

Risks Related to Ownership of Our Common Stock

Our stock price may be volatile or may decline regardless of our operating performance, resulting in substantial losses for investors.

The market price of our common stock has fluctuated upwards and downwards significantly in the past and is likely to be volatile in the future in response to numerous factors, many of which are beyond our control, including:

As a result of this volatility, payouts under, as well as the incentive value of, our stock-based compensation arrangements for employees can fluctuate and investors may experience losses on their investment in our common stock.

An active trading market for our common stock may not be sustained.

Although our common stock is traded on the Nasdaq under the symbol “LESL”, there is a limited trading history on an active trading market for our common stock, which may not be sustained. Accordingly, no assurance can be given as to the following:

If an active market for our common stock with meaningful trading volume is not maintained, the market price of our common stock may decline materially. Consequently, stockholders may not be able to sell our common stock at prices equal to or greater than the price paid.

Future sales of common stock by existing stockholders could cause our stock price to decline.

If our existing stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market the trading price of our common stock could be adversely impacted. As of December 5, 2025, we had 9,290,311 shares of common stock outstanding. All such shares are eligible for resale in the public market, subject to applicable securities laws, including the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The trading price of our common stock could be adversely impacted if any of these certain significant stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market.

Transactions engaged in by our principal stockholders, our officers, or directors involving our common stock may have an adverse effect on the price of our stock.

Sales of our shares by our officers, directors, and principal stockholders could have the effect of lowering our stock price. The perceived risk associated with the possible sale of a large number of shares by these stockholders, or the adoption of significant short positions by hedge funds or other significant investors, could cause some of our stockholders to sell their stock, thus causing the price of our stock to decline. In addition, actual or anticipated downward pressure on our stock price due to actual or anticipated sales of stock by our

directors or officers could cause other institutions or individuals to engage in short sales of our common stock, which may further cause the price of our stock to decline.

From time to time, our directors and executive officers may sell shares of our common stock on the open market. These sales will be publicly disclosed in filings made with the SEC. In the future, our directors and executive officers may sell a significant number of shares for a variety of reasons unrelated to the performance of our business. Our stockholders may perceive these sales as a reflection on management’s view of the business and result in some stockholders selling their shares of our common stock. These sales could cause the price of our stock to drop.

We do not intend to pay dividends for the foreseeable future.

We currently intend to retain any future earnings to finance the operation and expansion of our business and we do not expect to declare or pay any dividends in the foreseeable future. As a result, stockholders must rely on sales of their common stock after price appreciation as the only way to realize any future gains on their investment.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management, and limit the market price of our common stock.

Provisions in our certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management. Our amended and restated certificate of incorporation and amended and restated bylaws include provisions that:

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. As a result, these provisions may adversely affect the market price and market for our common stock if they are viewed as limiting the liquidity of our stock or as discouraging takeover attempts in the future.

The provision of our seventh amended and restated certificate of incorporation, requiring exclusive forum in certain courts in the State of Delaware or the federal district court for the District of Delaware for certain types of lawsuits, may have the effect of discouraging lawsuits against our directors and officers.

Our seventh amended and restated certificate of incorporation requires, to the fullest extent permitted by law, that (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees or stockholders to us or our stockholders, creditors or other constituents, or a claim of aiding and abetting any such breach of fiduciary duty, (iii) any action asserting a claim against us or our directors or officers arising pursuant to any provision of the Delaware General Corporation Law (“DGCL”) or our seventh amended and restated certificate of incorporation or our amended and restated bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, (iv) any action to interpret, apply, enforce or determine the validity of our seventh amended and restated certificate of incorporation or amended and restated bylaws, (v) any action asserting a claim against us or our directors or officers governed by the internal affairs doctrine or (vi) any action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL will have to be brought only in the Court of Chancery of the State of Delaware (or if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction, any other state court of the State of Delaware, or if no state court of the State of Delaware has subject matter jurisdiction, the federal district court for the District of Delaware), unless we consent in writing to the selection of an alternative forum. The foregoing provision will not apply to claims arising under the Exchange Act or the Securities Act of 1933, as amended (the “Securities Act”). Unless we consent in writing to the selection of an alternative forum, the federal district court for the District of Delaware shall be, to the fullest extent permitted by law, the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act against us or any of our directors or officers. Although we believe these exclusive forum provisions benefit us by providing increased consistency in the application of Delaware law and federal securities laws in the types of lawsuits to which each applies, the exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, or stockholders, which may discourage lawsuits with respect to such claims. Our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder as a result of our exclusive forum provisions. Further, in the event a court finds either exclusive forum provision contained in our seventh amended and restated certificate of incorporation to be unenforceable or inapplicable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results, and financial condition.

We will continue to incur increased costs as a result of being a public company, and our management will continue to be required to devote substantial time to compliance with our public company responsibilities and corporate governance practices.

As a company with publicly traded securities, we incur greater costs associated with corporate governance requirements that are applicable to us as a public company, including rules and regulations of the SEC, under the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley Act”), the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the Exchange Act, as well as the Nasdaq listing requirements. These rules and regulations significantly increase our accounting, legal, and financial compliance costs and make some activities more time-consuming. These rules and regulations make it more expensive for us to maintain directors’ and officers’ liability insurance. As a result, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers. Furthermore, these rules and regulations will continue to increase our legal and financial compliance costs and will make some activities more time-consuming and costly. We cannot predict or estimate the amount of additional costs we will continue to incur as a public company or the timing of such costs. Accordingly, increases in costs incurred as a result of being a publicly traded company may adversely affect our business, financial condition, and results of operations.

Our common stock may be delisted from The Nasdaq Global Select Market if we are unable to maintain compliance with Nasdaq's continued listing standards.

As previously disclosed, on April 24, 2025, we received notification from Nasdaq indicating that our common stock was subject to potential delisting from The Nasdaq Global Select Market because we were not in compliance with the requirement to maintain a minimum bid price of at least $1.00 (the “Bid Price Rule”). On September 26, 2025, we effected a 1-for-20 reverse stock split, and our common stock began trading on a reverse stock split-adjusted basis as of the open of trading on September 29, 2025. On October 14, 2025, we received a letter from the Listing Qualification Department (the “Staff”) of Nasdaq notifying us that we had regained compliance with the Bid Price Rule.

However, there can be no assurance that we will be able to maintain compliance with Nasdaq’s continued listing standards. If we do not maintain compliance with these standards, our common stock may be delisted from Nasdaq. Any delisting of our common stock would likely adversely affect the market liquidity and market price of our common stock and our ability to obtain financing for the continuation of our operations. Consequently, stockholders may not be able to sell our common stock at prices equal to or greater than the price paid.

We have identified material weaknesses in our internal control over financial reporting. If we are unable to remediate these material weaknesses, or if we experience additional material weaknesses or other deficiencies in the future or otherwise fail to maintain an

effective system of internal control over financial reporting, we may not be able to accurately or timely report our financial results, in which case our business may be harmed, investors may lose confidence in the accuracy and completeness of our financial reports, and our stock price could be adversely affected.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for evaluating and reporting on the effectiveness of our system of internal control. As a public company, we are also required by Section 404 of the Sarbanes-Oxley Act to evaluate the effectiveness of our internal control over financial reporting. We must also include a report issued by our independent registered public accounting firm based on their audit of our internal control over financial reporting.

In connection with our year-end assessment of internal control over financial reporting as part of this Annual Report on Form 10-K as of October 4, 2025 and September 28, 2024, we did not maintain effective internal control over financial reporting. For a discussion of our internal control over financial reporting and description of the identified material weaknesses and our remedial efforts, see Item 9A, Controls and Procedures of this Annual Report.

Completion of remediation does not provide assurance that our remediation or other controls will continue to operate properly. If we are unable to maintain effective internal control over financial reporting or disclosure controls and procedures, our ability to record, process and report financial information accurately, and to prepare financial statements within required time periods could be adversely affected, which could subject us to litigation or investigations requiring management resources and payment of legal and other expenses, negatively affect investor confidence in our financial statements and adversely impact our stock price.

Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition or results of operations. The effectiveness of our controls and procedures may be limited by a variety of factors, including:

•faulty human judgment and simple errors, omissions, or mistakes;

•fraudulent action of an individual or collusion of two or more people;

•inappropriate management override of procedures; and

•the possibility that any enhancements to controls and procedures may still not be adequate to assure timely and accurate financial control.

Our ability to comply with the annual internal control report requirements will depend on the effectiveness of our financial reporting and data systems and controls across our Company. We expect the modification, enhancement, or replacement of these systems and controls to involve significant expenditures and to become increasingly complex as our business grows. To effectively manage this complexity, we will need to continue to improve our operational, financial, and management controls, and our reporting systems and procedures. Our inability to successfully remediate our existing or any future material weaknesses or other deficiencies in our internal control over financial reporting or any failure to implement required new or improved controls, or difficulties encountered in the implementation or operation of these controls, could harm our operating results and cause us to fail to meet our financial reporting obligations or result in material misstatements in our financial statements, which could limit our liquidity and access to capital markets, adversely affect our business and investor confidence in us, and reduce our stock price.

Item 1B Unresolved Staff Comments

None.

Item 2. Properties.

Properties

As of October 4, 2025 we had over 1,000 locations in 39 states, two manufacturing facilities, and six distribution centers supporting our residential locations. In addition, we contract with third-party logistic providers under short-term agreements for additional capacity as needed. Most of our locations operate on five-year leases, which offer significant flexibility as they can be located in a variety of venues, including strip centers, lifestyle centers, and shopping centers. Our current physical network of store locations is summarized in the chart below:

Our corporate offices are located in Phoenix, Arizona. The 92,669 square foot office building has a current lease term through February 28, 2027, with our ability to exercise two five-year renewal options.

Item 3. Legal Proceedings.

On September 8, 2023, a class action complaint for violation of federal securities laws was filed by West Palm Beach Police Pension Fund in the U.S. District Court for the District of Arizona against us, our former Chief Executive Officer and our former Chief Financial Officer. The complaint alleges that the defendants violated federal securities laws by issuing materially false and misleading statements that failed to disclose adverse facts about our financial guidance, business operations and prospects, and seeks class certification, damages, interest, attorneys’ fees, and other relief. On April 22, 2024, the defendants filed a motion to dismiss the complaint. That court granted that motion and dismissed the claims on July 14, 2025. The court allowed the plaintiff to file a second amended complaint. On August 13, 2025, the plaintiff filed the second amended complaint. On September 12, 2025, the defendants filed a motion to dismiss the second amended complaint. That motion is fully briefed and pending before the court. Due to the early stage of this proceeding, we cannot reasonably estimate the potential range of loss, if any. We dispute the allegations of wrongdoing and intend to defend ourselves vigorously in this matter.

On March 13, 2024, March 14, 2024, and December 17, 2024, three derivative actions were separately filed in the U.S. District Courts for the Districts of Arizona and Delaware by John Clemens, Sally Flynn, and Ian Mednick, respectively, on behalf of the Company, and against its current and former officers and directors. Each of the three complaints include allegations similar to those in the securities class action, and allege that the defendant directors and officers harmed the Company by either making false or misleading statements, or allowing false or misleading statements to be made. The complaints seek the award of damages, costs, attorneys’ fees, and other declaratory relief. The two derivative actions pending in the U.S. District Court for the District of Arizona have been consolidated into a single proceeding. All of the derivative actions are stayed pending a decision on the motion to dismiss in the securities class action. Due to the early stage of these proceedings, we cannot reasonably estimate the potential range of loss, if any. We dispute the allegations of wrongdoing and intend to defend ourselves vigorously in these matters.

We are subject to other litigation, claims, and other proceedings that arise from time-to-time in the ordinary course of business. We believe these actions are routine and incidental to the business. As of October 4, 2025, we had established reserves for claims that are probable and estimable and such reserves were not significant. While we cannot feasibly predict the outcome of these matters with certainty, we believe, based on examination of these matters, experience to date and discussions with counsel, that the ultimate liability, individually or in the aggregate, will not have a material adverse effect on our business, financial position, results of operations, or cash flows.

Item 4. Mine Safety Disclosures.

Not applicable.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Our common stock is listed on Nasdaq under the “LESL” symbol and began “regular way” trading on Nasdaq on October 29, 2020. Prior to that date, there was no public trading market for our common stock.

As of December 5, 2025, there were two stockholders of record, although there is a much larger number of beneficial holders. The actual number of stockholders is greater than the number of record holders stated above, and includes stockholders who are beneficial owners, but whose shares are held in “street name” by brokers and other nominees.

Stock Performance Chart

This performance graph shall not be deemed “filed” with the SEC for purposes of Section 18 of the Exchange Act or incorporated by reference into any filing of Leslie’s, Inc. under the Securities Act or the Exchange Act.

The graph below presents our cumulative total shareholder returns on our common stock relative to the performance of the Nasdaq Global Composite Index and the S&P SmallCap 600 Index. The graph assumes $100 was invested at the market close on October 29, 2020, which was the first day our common stock began trading and its relative performance is tracked through October 4, 2025. Data for the Nasdaq Global Composite Index, and S&P SmallCap 600 Index assume reinvestment of dividends. The graph uses the closing market price on October 29, 2020 of $434.00 per share (as adjusted for the Reverse Stock Split) as the initial value of our common stock. The comparisons in the graph below are based upon historical data and are not indicative of, nor intended to forecast, future performance of our common stock:

Dividends

We have never declared nor paid any cash dividends on our common stock. We currently do not expect to pay any dividends on our common stock in the foreseeable future. Any future determination relating to our dividend policy will be made by our board of directors and will depend on a number of factors, including: our actual and projected financial condition, liquidity, and results of operations; our capital levels and needs; tax considerations; any acquisitions or potential acquisitions; statutory and regulatory prohibitions and other limitations; the terms of any credit agreements or other borrowing arrangements that restrict the amount of cash dividends that we can pay; general economic conditions; and other factors deemed relevant by our board of directors. We are not obligated to pay dividends on our common stock.

Recent Sales of Unregistered Securities

None.

Item 6. [Reserved].

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial statements and related notes, which are included elsewhere in this Annual Report on Form 10-K. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Actual results or outcomes may differ materially from those anticipated in these forward-looking statements, which are subject to risks, uncertainties, and other factors, including those described in Part I, Item 1A, “Risk Factors” of this Annual Report on Form 10-K for the fiscal year ended October 4, 2025.

We operate on a fiscal calendar that results in a fiscal year consisting of a 52- or 53-week period ending on the Saturday closest to September 30th. In a 52-week fiscal year, each quarter contains 13 weeks of operations; in a 53-week fiscal year, each of the first, second, and third quarters includes 13 weeks of operations and the fourth quarter includes 14 weeks of operations. References to fiscal 2025, 2024, and 2023 refer to the fiscal years ended October 4, 2025, September 28, 2024, and September 30, 2023. Fiscal 2025 included 53 weeks of operations and 2024 and 2023, included 52 weeks of operations.

Our Company

Founded in 1963 by Phil Leslie Jr. in Southern California, the Company today known simply as “Leslie’s” has over six
decades of disruptive retail innovation in the $15 billion U.S. pool and spa care industry. Today, we are the largest and most trusted direct-to-consumer brand in our segment, serving residential consumers and pool professionals, and many of the largest commercial property operators in the country. With over 1,000 retail locations, an integrated, digitally forward omnichannel strategy, and a horizontally integrated, nationwide ecosystem under the Leslie’s and In the Swim® brands, among others, we have built a market-leading share of residential aftermarket product spend, based on 2024 industry analyst reports, and a physical network larger than the sum of our 20 largest competitors. We offer an extensive assortment of professional-grade products, the majority of which are exclusive to Leslie’s, manufacturer certified installation and repair services, and in some markets, weekly pool maintenance services. Our dedicated, knowledgeable team of associates, pool and spa care experts, and experienced service technicians, are passionate about empowering every single Leslie’s customer with the knowledge, products, and solutions necessary to confidently maintain and thoroughly enjoy their pools and spas. The considerable scale of our integrated marketing and distribution ecosystem, which is powered by our direct-to-consumer network, uniquely enables us to efficiently reach and service nearly every pool and spa in the continental United States.

We operate primarily in the pool and spa aftermarket industry, a fundamentally attractive category in retail, given its scale, historical predictability, and growth outlook. More than 85% of our product assortment is comprised of non-discretionary products essential to the care of residential and commercial pools and spas. This includes chemicals, new and replacement parts, cleaning and maintenance equipment, safety, recreational, and fitness-related products. We also offer important essential services, such as equipment installation and repair for residential and commercial customers. We have relationships with professional pool operators from major hotel and apartment owners to municipal, county and state governments, all the way to sole proprietors. In addition to a strong consumer and commercial retail and service presence, we operate a wholesale specialty pool and spa parts distribution business, giving us unique access to hard-to-find specialty parts; an integrated manufacturing plant, giving us vertical scale and competitive cost on parts of our chemical assortment; and a regionally located, hub-and-spoke distribution system throughout the continental United States.

We offer complimentary, commercial-grade in-store water testing and analysis via our proprietary AccuBlue® system, leading to increased consumer engagement, conversion, basket size, and loyalty, resulting in higher lifetime value. Our water treatment expertise is powered by data and intelligence accumulated from the millions of water tests we have performed over the years, positioning us as the most trusted water treatment service provider in the recreational pool and spa industry. We then brought AccuBlue® direct to pool owners’ backyards with AccuBlue Home®, a pioneering app-enabled water testing device. These differentiated capabilities allow us to meet the needs of any pool and spa owner, whether they care for their pool or spa themselves or rely on a professional, whenever, wherever, and however they choose to engage with us.

Key Factors and Measures We Use to Evaluate Our Business

We consider a variety of financial and operating measures in assessing the performance of our business. The key measures we use under United States generally accepted accounting principles (“GAAP”) are sales, gross profit and gross margin, selling, general, and administrative expenses (“SG&A”), and operating income (loss). The key non-GAAP measures and other operating measures we use are comparable sales, comparable sales growth, Adjusted EBITDA, Adjusted net income (loss), and Adjusted diluted earnings per share.

Sales

We offer a broad range of products that consists of regularly purchased, non-discretionary pool and spa maintenance items such as chemicals, equipment, cleaning accessories and parts, as well as installation and repair services for pool and spa equipment. Our offering of proprietary, owned, and third-party brands across diverse product categories drives sales growth by attracting new consumers and encouraging repeat visits from our existing consumers. Revenue from merchandise sales at retail locations is recognized at the point of sale, revenue from services is recognized when the services are rendered, and revenue from e-commerce merchandise sales is generally recognized upon shipment of the merchandise. Revenue is recorded net of related discounts and sales tax. Payment from retail customers is generally at the point of sale and payment terms for professional pool operator customers are based on our credit requirements and generally have terms of less than 60 days. When we receive payment from a consumer before the consumer has taken possession of the merchandise or the service has been performed, the amount received is recorded as deferred revenue or as a customer deposit until the sale or service is complete. Sales are impacted by weather, seasonality, product mix and availability, promotional and competitive activities and the spending habits of our consumers, as well as inflation and interest rates. Growth of our sales is primarily driven by comparable sales growth and expansion of our locations in existing and new markets.

Comparable Sales and Comparable Sales Growth

We measure comparable sales growth as the increase or decrease in sales recorded by the comparable base in any reporting period, compared to sales recorded by the comparable base in the prior reporting period. The comparable base includes sales through our locations and through our e-commerce websites and third-party marketplaces. Comparable sales growth is a key measure used by management and our board of directors to assess our financial performance.

We consider a new or acquired location comparable in the first full month after it has completed one year of sales. Closed locations become non-comparable during their last partial month of operation. Locations that are relocated are considered comparable at the time the relocation is complete. Comparable sales is not calculated in the same manner by all companies, and accordingly, is not necessarily comparable to similarly titled measures of other companies and may not be an appropriate measure for performance relative to other companies.

The number of new locations reflects the number of locations opened during a particular reporting period. New locations require an initial capital investment in location buildouts, fixtures, and equipment, which we amortize over time as well as cash required for inventory.

As of October 4, 2025, we operated over 1,000 locations in 39 states across the United States. We owned 27 locations and leased the remainder of our locations. Our initial lease terms are typically five years with options to renew for multiple successive five-year periods. We evaluate new opportunities in new and existing markets based on the number of pools and spas in the market, competition, our existing locations, availability and cost of real estate, and distribution and operating costs of our locations. We review the performance of our locations on a regular basis and evaluate opportunities to strategically close locations to improve our profitability. Our limited investment costs in individual locations and our ability to transfer sales to our extensive network of remaining locations and e-commerce websites allows us to improve profitability as a result of any strategic closures.

Gross Profit and Gross Margin

Gross profit is equal to our sales less our cost of merchandise and services sold. Cost of merchandise and services sold reflects the direct cost of purchased merchandise, costs to package certain chemical products, including direct materials and labor, costs to provide services, including labor and materials, as well as distribution and occupancy costs. The direct cost of purchased merchandise includes vendor rebates. We recognize vendor rebates based on an estimated recognition pattern using historical data. Distribution costs include warehousing and transportation expenses, including costs associated with third-party fulfillment centers used to ship merchandise to our e-commerce consumers. Occupancy costs include the rent, common area maintenance, real estate taxes, and depreciation and amortization costs of all retail locations. These costs are significant and are expected to continue to increase proportionate to our growth.

Gross margin is gross profit as a percentage of our sales. Gross margin is impacted by merchandise costs, pricing and promotions, product mix and availability, inflation, and service costs, which can vary. Our proprietary brands, custom-formulated products, and vertical integration provide us with cost savings, as well as greater control over product availability and quality as compared to other companies in the industry. Gross margin is also impacted by the costs of distribution and occupancy costs, which can vary.

Our gross profit is variable in nature and generally follows changes in sales. The components of our cost of merchandise and services sold may not be comparable to the components of cost of sales or similar measures of other companies. As a result, our gross profit and gross margin may not be comparable to similar data made available by other companies.

Selling, General and Administrative Expenses

Our SG&A includes selling and operating expenses across our retail locations and digital platform, and our corporate-level general and administrative expenses. Selling and operating expenses at retail locations include payroll, bonus and benefit costs for personnel, supplies, and credit and debit card processing costs. Corporate expenses include payroll, bonus, and benefit costs for our corporate and field support functions, equity-based compensation, marketing and advertising, insurance, utilities, occupancy costs related to our corporate office facilities, professional services, and depreciation and amortization for all assets, except those related to our retail locations and distribution operations, which are included in cost of merchandise and services sold. Selling and operating expenses generally vary proportionately with sales and the change in the number of locations. In contrast, general and administrative expenses are generally not directly proportional to sales and the change in the number of locations, but may increase over time to support our growth and public company obligations. The components of our SG&A may not be comparable to the components of similar measures of other companies.

Impairments

The impairments were non-cash charges resulting from a decline in our operating results, store performance, and market capitalization. These charges were due to (i) the carrying value of our single reporting unit’s goodwill being greater than the calculated fair value in the case of goodwill impairment and (i) the carrying value of our store assets being greater than the fair value in the case of asset impairment.

Operating Income (Loss)

Operating income (loss) is gross profit less SG&A. Operating income (loss) excludes interest expense, loss on debt extinguishment, income tax expense (benefit), and other (income) expenses, net. We use operating income (loss) as an indicator of the productivity of our business and our ability to manage expenses.

Adjusted EBITDA

Adjusted EBITDA is defined as earnings before interest (including amortization of debt issuance costs), taxes, depreciation and amortization, equity-based compensation expense, executive transition costs, severance, strategic project costs, merger and acquisition costs, and other non-recurring, non-cash or discrete items. Adjusted EBITDA is a key measure used by management and our board of directors to assess our financial performance. Adjusted EBITDA is also frequently used by analysts, investors, and other interested parties to evaluate companies in our industry, when considered alongside other GAAP measures. We use Adjusted EBITDA to supplement GAAP measures of performance to evaluate the effectiveness of our business strategies, to make budgeting decisions, and to compare our performance against that of other companies using similar measures.

Adjusted EBITDA is not a recognized measure of financial performance under GAAP but is used by some investors to determine a company’s ability to service or incur indebtedness. Adjusted EBITDA is not calculated in the same manner by all companies, and accordingly, is not necessarily comparable to similarly titled measures of other companies and may not be an appropriate measure for performance relative to other companies. Adjusted EBITDA should not be construed as an indicator of a company’s operating performance in isolation from, or as a substitute for, net income (loss), cash flows from operations or cash flow data, all of which are prepared in accordance with GAAP. We have presented Adjusted EBITDA solely as supplemental disclosure because we believe it allows for a more complete analysis of results of operations. Adjusted EBITDA is not intended to represent, and should not be considered more meaningful than, or as an alternative to, measures of operating performance as determined in accordance with GAAP. In the future, we may incur expenses or charges such as those added back to calculate Adjusted EBITDA. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these items.

Adjusted Net Income (Loss) and Adjusted Diluted Earnings (loss) per Share

Adjusted net income (loss) and Adjusted diluted earnings (loss) per share are additional key measures used by management and our board of directors to assess our financial performance. Adjusted net income (loss) and Adjusted diluted earnings (loss) per share are also frequently used by analysts, investors, and other interested parties to evaluate companies in our industry, when considered alongside other GAAP measures.

Adjusted net income (loss) is defined as net income (loss) adjusted to exclude equity-based compensation expense, executive transition costs, severance, strategic project costs, merger and acquisition costs, change in valuation allowance for deferred taxes, and other non-recurring, non-cash, or discrete items. Adjusted diluted earnings (loss) per share is defined as Adjusted net income (loss) divided by the diluted weighted average number of common shares outstanding.

Factors Affecting the Comparability of our Results of Operations

Our reported results have been affected by, among other events, the following events, which must be understood in order to assess the comparability of our period-to-period financial performance and condition.

Impact of Macroeconomic Events and Uncertainties

Our financial performance and condition may be impacted to varying extents from period to period by macroeconomic and geopolitical developments, including public health crises, escalating global conflicts, tariffs, supply chain disruptions, labor market constraints, high rates of inflation, high interest rates, general economic slowdown, and potential failures among financial institutions. New or increased tariffs and other barriers to trade, especially in light of comments and executive orders made by the U.S. presidential administration, could further impact or exacerbate these conditions. The United States has announced tariffs on imports from most countries, including significant tariffs on imports from Canada, Mexico and China. In response to tariffs, other countries have implemented retaliatory tariffs on U.S. goods. There is substantial uncertainty about the duration of existing tariffs and whether additional tariffs may be imposed, modified or suspended, and the impacts of such actions on the Company’s business. Significant disruption to our supply chain for products we sell, as a result of geopolitical conflict, tariffs or trade policies or otherwise, can also have a material impact on our sales and earnings and cause unpredictable changes in results. In addition, we believe adverse macroeconomic trends and uncertainties including inflation, tariffs, and varying interest rates also increase consumers’ sensitivity to price and result in cost-conscious behavior inclusive of high ticket items, which can result in corresponding declines in sales and/or gross profit.

Additional uncertainties that can impact our results of operations are consumer purchasing patterns and consumer cost-consciousness. In the past, we believe some customers stockpiled chemicals, resulting in unexpected changes in demand. As a result of such behavior, our revenue may be higher than normal during the periods of stockpiling and may be lower than normal during the periods after stockpiling has occurred.

Reverse Stock Split

On September 10, 2025, our shareholders approved a series of amendments to our Seventh Amended and Restated Certificate of Incorporation (the “Certificate of Amendment”). On September 26, 2025, we filed a Certificate of Amendment with the Secretary of State of the State of Delaware to effect a reverse stock split of our comment stock at a ratio of 1-for-20 (the “Reverse Stock Split”) and proportionately decrease the number of authorized shares of the Company’s common stock, which became effective upon filing (the “Effective Time”). The Company’s common stock began trading on a Reverse Stock Split-adjusted basis on Nasdaq as of the open of trading on September 29, 2025 under the existing ticker symbol “LESL”. The Company’s common stock is now represented by a new CUSIP number, 527064 208.

As a result of the Reverse Stock Split, every 20 shares of our common stock issued and outstanding as of the Effective Time of the Reverse Stock Split was automatically converted into one share of common stock. No fractional shares were issued as a result of the Reverse Stock Split. The Company’s transfer agent aggregated all fractional shares of common stock that would otherwise have been issuable as a result of the Reverse Stock Split and sold them at the then prevailing prices on the open market on behalf of those shareholders who would otherwise be entitled to receive such fractional shares. Shareholders who otherwise would be entitled to receive fractional shares received their respective pro rata share of the total proceeds of such sale.

In addition, as of the Effective Time and as a result of the Reverse Stock Split, proportionate adjustments were made in accordance with the terms of the Company’s 2020 Omnibus Incentive Plan (the “Incentive Plan”), with respect to the number of shares of common stock issuable under outstanding stock options, restricted stock units and performance units, and any other equity-based awards, the per-share

exercise price with respect to such awards, and the number of shares of common stock reserved for future issuance under the Incentive Plan.

All share and per share amounts presented herein have been retroactively adjusted to reflect the Reverse Stock Split for all years.

Results of Operations

We derived our consolidated statements of operations for fiscal 2025, 2024, and 2023 from our consolidated financial statements. Our historical results are not necessarily indicative of the results that may be expected in the future. The following table summarizes key components of our results of operations for the years indicated, both in dollars and as a percentage of our sales (in thousands, except per share amounts and percentages):

Comparison of Fiscal 2025 and 2024

Sales

Sales decreased to $1,241.9 million in fiscal 2025 compared to $1,330.1 million in fiscal 2024, a decrease of $88.2 million, or 6.6%. The decrease was primarily driven by reductions in traffic and a lower number of transactions. Comparable sales decreased $91.4

million, or 6.8%, compared to fiscal 2024, primarily driven by declines in traffic and average order value. Non-comparable sales, including acquisitions and new stores, were $3.2 million in fiscal 2025.

Gross Profit and Gross Margin

Gross profit decreased to $439.6 million in fiscal 2025 compared to $476.8 million in fiscal 2024, a decrease of $37.1 million or 7.8%. Gross margin decreased to 35.4% compared to 35.8% in fiscal 2024, a decrease of 40 basis points. The decrease in gross margin was primarily driven by negative impacts of 100 basis points from deleverage on occupancy costs partially offset by 60 basis point benefit from product rate.

Selling, General and Administrative Expenses

SG&A increased to $425.7 million in fiscal 2025 compared to $419.7 million in fiscal 2024, an increase of $6.0 million or 1.4%. This increase in SG&A was primarily related to increases of $7.7 million in compensation expenses, $4.4 million in professional fees and consulting expenses, $1.9 million in direct store expenses, and $1.4 million in information and technology spend. These increases were partially offset by decreases of $3.6 million in merchant fees, and $2.9 million in marketing fees.

Impairment

Impairment charges increased to $183.8 million in fiscal 2025. The impairment was comprised of a $180.7 million impairment to goodwill and $3.1 million asset write offs for underperforming stores. No impairment charges were recorded in the prior year.

Interest Expense

Interest expense decreased to $62.9 million in fiscal 2025 compared to $70.4 million in fiscal 2024, a decrease of $7.5 million. This decrease was primarily due to lower interest rates on our Term Loan and Revolving Credit Facility combined with a lower balance on the Term Loan.

Income Taxes

Income tax expense was $4.2 million in fiscal 2025 compared to $10.1 million in fiscal 2024, a decrease of $5.9 million. The change in income tax expense was the result of the $45.0 million increase in the non-cash valuation allowance against our deferred tax assets, plus the permanent effects of the goodwill impairment recorded during fiscal 2025, partially offset by a larger pretax loss in fiscal 2025 compared to fiscal 2024. Our effective tax rate was (1.8%) for fiscal 2025 compared to (76.1%) for fiscal 2024.

Net Loss and Diluted Loss per Share

Net loss was $237.0 million in fiscal 2025 compared to net loss of $23.4 million in fiscal 2024, a change of $213.6 million. The increase in net loss was primarily driven by lower sales volume during fiscal 2025, combined with impairments recorded during the year. Diluted earnings per share decreased to $(25.57) in fiscal 2025 compared to $(2.53) in fiscal 2024.

Adjusted net loss was $43.7 million in fiscal 2025 compared to a loss of $1.1 million in fiscal 2024, a change of $42.6 million. Adjusted diluted loss per share was $(4.71) in fiscal 2025 compared to $(0.12) in fiscal 2024.

Adjusted EBITDA

Adjusted EBITDA decreased to $61.4 million in fiscal 2025 compared to $108.7 million in fiscal 2024, an decrease of $47.4 million. The decrease was primarily driven by lower sales volume during fiscal 2025, combined with decreases in occupancy deleverage and higher SG&A. These impacts were partially offset by higher product rate.

Comparison of Fiscal 2024 and 2023

Sales

Sales decreased to $1,330.1 million in fiscal 2024 compared to $1,451.2 million in fiscal 2023, a decrease of $121.1 million, or 8.3%, primarily driven by declines in traffic and average order value. Comparable sales decreased $127.4 million, or 8.8%, compared to fiscal 2023, Non-comparable sales including acquisitions and new stores were $7.9 million in fiscal 2024.

Gross Profit and Gross Margin

Gross profit decreased to $476.8 million in fiscal 2024 compared to $548.2 million in fiscal 2023, a decrease of $71.4 million or 13.0%. Gross margin decreased to 35.8% compared to 37.8% in fiscal 2023, a decrease of 200 basis points. The decrease in gross margin was primarily driven by negative impacts of 121 basis points from product rate, 94 basis points from deleverage on occupancy costs and 50 basis points from the expensing of previously capitalized distribution center costs due to significant reductions in inventory during fiscal 2024. Additionally, there was a one-time item of approximately $5.0 million related to rebates and warranties on a contract that has subsequently been revised. The impacts discussed above were partially offset by a 72 basis point reduction related to inventory adjustments and distribution costs.

Selling, General and Administrative Expenses

SG&A decreased to $419.7 million in fiscal 2024 compared to $446.0 million in fiscal 2023, a decrease of $26.3 million or 5.9%. This decrease in SG&A was primarily related to a decrease merchant fees of $6.0 million associated with lower sales, a decrease in payroll costs of $4.0 million mainly due to lower headcount, a decrease in asset write offs of $5.9 million, a decrease in equity compensation of $3.4 million, a decrease in bonus and commissions of $1.9 million, and a decrease in marketing expenses of $1.6 million.

Interest Expense

Interest expense increased to $70.4 million in fiscal 2024 compared to $65.4 million in fiscal 2023, an increase of $5.0 million. This increase was primarily due to higher interest rates on our Term Loan and Revolving Credit Facility.

Income Taxes

Income tax expense was $10.1 million in fiscal 2024 compared to $9.5 million in fiscal 2023, an increase of $0.6 million. The change in income tax expense was the result of the impact of limitations on interest expense deductibility requiring us to record a $11.2 million non-cash valuation allowance against our deferred tax asset, partially offset by pretax loss in 2024, compared to pretax income in 2023. Our effective tax rate was -76.1% for fiscal 2024 compared to 25.9% for fiscal 2023.

Net (Loss) Income and Diluted Earnings per Share

Net loss was $23.4 million in fiscal 2024 compared to net income of $27.2 million in fiscal 2023, a change of $50.6 million. Diluted earnings per share decreased to $(2.53) in fiscal 2024 compared to $2.95 in fiscal 2023.

Adjusted net loss was $1.1 million in fiscal 2024 compared to income of $51.1 million in fiscal 2023, a change of $52.2 million. Adjusted diluted earnings per share decreased to $(0.12) in fiscal 2024 compared to $5.54 in fiscal 2023.

Adjusted EBITDA

Adjusted EBITDA decreased to $108.7 million in fiscal 2024 compared to $168.1 million in fiscal 2023, a decrease of $59.4 million. The decrease was primarily driven by lower sales volume during fiscal 2024, combined with decreases in gross margin, driven by higher product rate and occupancy deleverage. These decreases were partially offset by lower SG&A and inventory adjustments.

Seasonality and Quarterly Fluctuations

Our business is highly seasonal. Sales and earnings are highest during the third and fourth fiscal quarters, which include April through September, and represent the peak months of swimming pool use. Sales are substantially lower during our first and second fiscal quarters when we typically generate net losses and we realize negative operating cash flows. We have a long track record of investing in our business throughout the year, including in operating expenses, working capital, and capital expenditures related to new locations and other growth initiatives. While these investments drive performance during the primary selling season in our third and fourth fiscal quarters, they have a negative impact on our earnings and cash flow during our first and second fiscal quarters.

We typically experience a build-up of inventory and accounts payable during the first and second fiscal quarters in anticipation of the peak swimming pool supply selling season. We negotiate extended payment terms with certain of our primary suppliers as we receive merchandise in December through March, and we pay for merchandise in April through July.

The principal external factor affecting our business is weather. Hot weather can increase purchases of chemicals and other non-discretionary products as well as purchases of discretionary products and can drive increased purchases of installation and repair services.

Unseasonably cool weather or significant amounts of rainfall during the peak pool sales season can reduce chemical consumption in pools and spas and decrease consumer purchases of our products and services. In addition, unseasonably early or late warming trends can increase or decrease the length of the pool season and impact timing around pool openings and closings and, therefore, our total sales and timing of our sales. Further, we generally close locations after our peak selling season ends. During this year, we experienced unseasonably cold and rainy weather in the North East in May and June, which we believe delayed the start to the pool season and pool openings.

Liquidity and Capital Resources

Overview

Our primary sources of liquidity are net cash provided by operating activities and borrowing availability under our Revolving Credit Facility. Historically, we have funded working capital requirements, capital expenditures, payments related to acquisitions, and debt service requirements with internally generated cash on hand and through our Revolving Credit Facility.

Cash and cash equivalents consist primarily of cash on deposit with banks. Cash and cash equivalents totaled $64.3 million and $108.5 million as of October 4, 2025 and September 28, 2024. As of October 4, 2025 and September 28, 2024, we did not have any outstanding borrowings under our Revolving Credit Facility.

Our primary working capital requirements are for the purchase of inventory, payroll, rent, other facility costs, distribution costs, and general and administrative costs. Our working capital requirements fluctuate during the year, driven primarily by seasonality and the timing of inventory purchases.

Our capital expenditures are primarily related to infrastructure-related investments, including investments related to upgrading and maintaining our information technology systems, ongoing location improvements, expenditures related to our distribution centers, and new location openings. We expect to fund capital expenditures from net cash provided by operating activities.

Based on our growth plans, we believe our cash and cash equivalents position, net cash provided by operating activities and borrowing availability under our Revolving Credit Facility will be adequate to finance our working capital requirements, planned capital expenditures, strategic acquisitions, share repurchases, and debt service over the next 12 months and thereafter. If cash provided by operating activities and borrowings under our Revolving Credit Facility are not sufficient or available to meet our capital requirements, then we may need to obtain additional equity or debt financing. There can be no assurance that equity or debt financing will be available to us if we need it or, if available, whether the terms will be satisfactory to us.

As of October 4, 2025, outstanding standby letters of credit totaled $11.7 million, and after considering borrowing base restrictions we had $167.9 million of availability from cash on hand and available borrowing capacity under the terms of the Revolving Credit Facility. As of October 4, 2025, we were in compliance with the covenants under the Revolving Credit Facility and our Term Loan agreements. Additionally, during the first quarter of fiscal 2025, we repaid $25.0 million on our Term Loan.

During the quarter ended October 4, 2025, the Company received downgraded credit ratings from both Moody’s to (Caa3 from Caa1) and Standard and Poor’s (“S&P”) Global Ratings to (B- from B).

Summary of Cash Flows

A summary of our cash flows from operating, investing, and financing activities is presented in the following table (in thousands):

Cash Provided by Operating Activities

Net cash provided by operating activities was $8.8 million in fiscal 2025 compared to $107.5 million in fiscal 2024. This decrease was driven by the higher net loss in 2025 due to lower sales during fiscal 2025 combined with higher uses of cash for net working capital.

Net cash provided by operating activities was $107.5 million in fiscal 2024 compared to $6.5 million in fiscal 2023. This increase was primarily driven by changes in working capital related to reductions in inventories of $85.9 million, increases in accounts payable and accrued expenses of $6.7 million, partially offset by an increase in accounts receivable of $18.7 million.

Cash Used in Investing Activities

Net cash used in investing activities was $25.4 million in fiscal 2025 compared to $47.2 million in fiscal 2024. This decrease was driven by a decrease in purchases of property and equipment.

Net cash used in investing activities was $47.2 million in fiscal 2024 compared to $52.5 million in fiscal 2023. This decrease was driven by lower investments for business acquisitions, partially offset by increased purchases of property and equipment.

Cash Used in Financing Activities

Net cash used in financing activities was $27.6 million in fiscal 2025 compared to $7.2 million in fiscal 2024. This increase was primarily driven by higher repayments of long-term debt in fiscal 2025.

Net cash used in financing activities was $7.2 million in fiscal 2024 compared to $10.8 million in fiscal 2023. This decrease was primarily driven by lower payments of employee tax withholding related to restricted stock vesting.

Contractual Obligations and Other Commitments

The following table summarizes our contractual cash obligations as of October 4, 2025 (in thousands):

Critical Accounting Estimates

The preparation of our consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the reported periods. The SEC has defined a company’s critical accounting policies as the ones that are most important to the portrayal of a company’s financial condition and results of operations, and which require a company to make its most difficult and subjective judgments. Based on this definition, we have identified the critical accounting policies and judgments, which are disclosed in this Annual Report on Form 10-K for the fiscal year ended September 28, 2024. We base these estimates on historical results and various other assumptions we believe to be reasonable, all of which form the basis for making estimates concerning the carrying values of assets and liabilities that are not readily available from other sources. Actual results may differ from these estimates.

Vendor Rebates

Many of our vendor arrangements provide for us to receive specified amounts of consideration meet the criteria defined in the agreement. Generally, the criteria relate to the volume level of purchases. We calculate the amount earned based on actual purchases, recorded as a reduction of the prices of the vendor’s products and therefore a reduction of inventory at the end of each period based on a detailed analysis of inventory and of the facts and circumstances of various contractual agreements with vendors. We recognize rebates based on an estimated recognition pattern using historical data, and we record this as a reduction of cost of merchandise and services sold in our consolidated statements of operations. We do not believe there is a reasonable likelihood there will be a material change in the future estimates or assumptions we use to calculate our reduction of inventory.

Inventories

Inventories are stated at the lower of cost or net realizable value. We value inventory using the average cost method which includes costs incurred to deliver inventory to our distribution centers including transportation, warehousing and distribution costs. We evaluate inventory for excess and obsolescence and record necessary reserves. We provide provisions for losses related to inventories based on management’s judgment regarding historical purchase cost, selling price, margin, and current business trends. If actual demand or market conditions are different than those projected by management, future margins may be unfavorably or favorably affected by adjustments to these estimates. When an inventory item is sold or disposed, the associated reserve is released at that time. We do not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions used to calculate our inventory reserve.

Goodwill and Other Intangibles, Net

Goodwill and intangible assets are recorded at their estimated fair values at the date of acquisition. We review goodwill and indefinite-lived intangible assets for impairment annually (in the fourth quarter) or more frequently if impairment indicators arise. Goodwill can be evaluated for impairment, at our option, by first performing a qualitative assessment to determine whether a quantitative goodwill test is necessary. If it is determined, based on qualitative factors, that the fair value of the reporting unit may be more likely than not less than the carrying amount, a quantitative goodwill impairment test would be required. Additionally, we can elect to forgo a qualitative assessment and perform a quantitative test. The quantitative test is to identify if a potential impairment exists by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds the fair value, an impairment loss is recognized in an amount equal to that excess, not to exceed the carrying amount of goodwill.

If a quantitative test is performed, we would estimate the value considering the use of various valuation techniques which may use significant unobservable inputs, or Level 3 inputs, as defined by the fair value hierarchy. We include assumptions about sales growth, operating margins, discount rates and valuations multiples which consider our budgets, business plans, economic projections and marketplace data, and are believed to reflect market participant views which would exist in an exit transaction. Some of the inherent estimates and assumptions used in this analysis are outside the control of management, including cost of capital, tax rates and market EBITDA comparable financial metrics.

For our indefinite life intangible assets, a qualitative assessment can also be performed to determine whether the existence of events and circumstances indicates it is more likely than not the intangible asset is impaired. Similar to goodwill, we can also elect to forgo a qualitative test for indefinite life intangible assets and perform a quantitative test. Upon performing the quantitative test, if the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. We evaluate whether certain trade names continue to have an indefinite life annually.

We performed a quantitative assessment of goodwill during the fourth quarter of 2025 and recorded a $180.7 million impairment. See Note 3 - Goodwill and Other Intangibles, Net to our consolidated financial statements included elsewhere in this Annual Report on Form

10-K for further discussion.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

The interest rates on borrowings under our Revolving Credit Facility and Term Loan were LIBOR-based rates prior to March 2023 and June 2023. Due to the discontinuation of LIBOR-based rates, we have transitioned the impacted interest rate benchmarks to Term SOFR-based rates. See Note 9—Long-Term Debt, Net to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for additional information. Accordingly, we are subject to interest rate risk in connection with borrowings under our Revolving Credit Facility and Term Loan, both of which bear interest at variable rates. As of October 4, 2025, we had $756.7 million outstanding on our Term Loan. No amounts were outstanding on our Revolving Credit Facility as of such date. The impact of a 1.0% rate change on our outstanding balance less contractual amortization would total approximately $7.6 million over the next 12 months.

Impact of Inflation and Deflation

We experience inflation and deflation related to our purchase of certain products. This price volatility could potentially have a material impact on our financial condition and/or our results of operations. We actively manage the impact of inflation, including tariffs, through strong relationships with our diverse supplier base, vendor negotiation, and promotion management. We also strategically invest through inventory purchases in order to obtain favorable pricing ahead of any vendor price increases. In order to mitigate price volatility, we monitor price fluctuations and may adjust our selling prices accordingly; however, our ability to recover higher costs through increased pricing may be limited by the competitive environment in which we operate. Although we may experience periodic effects on sales, gross profit, gross margins, and cash flows as a result of changing prices, we do not expect the effect of inflation or deflation to have a material impact on our ability to execute our long-term business strategy. We currently do not use derivative instruments to manage these risks.
