PART I

Item 1. Business

We are a diversified international transportation services company and one of the world's premier automotive and commercial truck retailers. We operate dealerships in the United States, the United Kingdom, Canada, Germany, Italy, Japan, and Australia, and we are one of the largest retailers of commercial trucks in North America for Freightliner. We also distribute and retail commercial vehicles, diesel and gas engines, power systems, and related parts and services principally in Australia and New Zealand. We employ over 28,900 people worldwide. Additionally, we own 28.9% of Penske Transportation Solutions, a business that employs over 44,500 people worldwide, manages one of the largest, most comprehensive and modern trucking fleets in North America with over 435,000 trucks, tractors, and trailers under lease, rental, and/or maintenance contracts, and provides innovative transportation, supply chain, and technology solutions to its customers.

Business Overview

In 2024, our business generated $30.5 billion in total revenue, which is comprised of approximately $26.2 billion from retail automotive dealerships, $3.5 billion from retail commercial truck dealerships, and $777.9 million from commercial vehicle distribution and other operations. We generated $5.0 billion in gross profit, which is comprised of $4.3 billion from retail automotive dealerships, $584.5 million from retail commercial truck dealerships, and $178.2 million from commercial vehicle distribution and other operations.

Retail Automotive. We are one of the largest global automotive retailers as measured by the $26.2 billion in total retail automotive dealership revenue we generated in 2024. We are diversified geographically with 56% of our total retail automotive dealership revenues in 2024 generated in the U.S. and Puerto Rico and 44% generated outside of the U.S. We offer over 40 vehicle brands with 72% of our retail automotive franchised dealership revenue in 2024 generated from premium brands, such as Audi, BMW, Land Rover, Mercedes-Benz, and Porsche. As of December 31, 2024, we operated 353 retail automotive franchised dealerships, of which 148 are located in the U.S. and 205 are located outside of the U.S., principally in the U.K. As of December 31, 2024, we also operated 16 used vehicle dealerships, with six dealerships in the U.S. operating under the brand name CarShop, nine dealerships in the U.K. operating under the brand name Sytner Select, and one dealership in Australia operating under the brand name Penske Select. We retailed and wholesaled, including agency units, more than 594,000 vehicles in 2024.

In addition to selling new and used vehicles, we generate higher-margin revenue at each of our dealerships through maintenance and repair services, the sale and placement of third-party finance and insurance products, third-party extended service and maintenance contracts, replacement and aftermarket automotive products, and at certain of our locations, collision repair services. We operate our franchised dealerships under franchise agreements with a number of automotive manufacturers and distributors that are subject to certain rights and restrictions typical of the industry. Some of our dealerships in the U.K. and Europe operate under an agency model where we receive a fee for facilitating the sale by the manufacturer of a new vehicle but do not hold the vehicle in inventory. Vehicles sold under this agency model are counted as new agency units sold instead of new retail units sold by us, and only the fee we receive from the manufacturer, not the price of the vehicle, is reported as new revenue with no corresponding cost of sale.

We believe our diversified retail automotive income streams help to mitigate the historical cyclicality found in some elements of the automotive sector. Revenues from higher margin service and parts sales include warranty work, customer-paid work, rapid repair, collision repair services, and wholesale parts sales. Service and parts sales are typically less cyclical than retail vehicle sales and generate the largest part of our retail automotive gross profit.

The following graphics show the percentage of our total retail automotive dealership revenues by product type and their respective contribution to our retail automotive gross profit:

Retail Commercial Truck Dealership. We operate Premier Truck Group ("PTG"), a heavy- and medium-duty truck dealership group offering primarily Freightliner and Western Star trucks (both Daimler brands), with locations across 10 U.S. states and the Canadian provinces of Ontario and Manitoba. As of December 31, 2024, PTG operated 45 locations selling new and/or used trucks, performing service and parts operations, or offering collision repair services. We retailed and wholesaled 20,947 new and used trucks in 2024. These businesses represented 11.6% of our total revenues and 11.7% of our total gross profit in 2024.

While our retail commercial truck business benefits from diversified income streams similar to those of the retail automotive sector, there are several key differences. As exhibited in the following charts, a greater part of our gross profit is derived from the sale of service and parts in the retail truck business given the large volume of parts business, in many cases, to fleet customers. In addition, the commercial truck business has a historically lower selling, general, and administrative expense as a percentage of gross profit as compared to retail automotive as approximately 65% of PTG's gross profit is attributable to higher margin service and parts compared to retail automotive which is approximately 42%. The following graphics show the percentage of our total retail commercial truck dealership revenues by product type and their respective contribution to our retail commercial truck gross profit:

vehicles, together with associated parts, across Australia, New Zealand, and portions of the Pacific. In most of these same markets, we are also a leading distributor of diesel and gas engines and power systems, principally representing MTU (a Rolls-Royce solution), Detroit Diesel, Allison Transmission, and Bergen Engines. Penske Australia offers products across the on- and off-highway markets, including in the trucking, mining, power generation, energy solutions, defense, marine, rail, and construction sectors and supports full parts and aftersales service through a network of branches, field service locations, and dealers across the region. These businesses represented 2.5% of our total revenues and 3.5% of our total gross profit in 2024.

Penske Transportation Solutions. We hold a 28.9% ownership interest in Penske Truck Leasing Co., L.P. ("PTL"). PTL is owned 41.1% by Penske Corporation, 28.9% by us, and 30.0% by Mitsui & Co., Ltd. ("Mitsui"). We account for our investment in PTL under the equity method, and we therefore record our share of PTL's earnings on our statements of income under the caption "Equity in earnings of affiliates," which also includes the results of our other equity method investments. Penske Transportation Solutions ("PTS") is the universal brand name for PTS' various businesses, which articulates the breadth of its services. Its business was founded over 50 years ago, and today it is a leading provider of transportation and supply chain services. PTS is capable of meeting customers' needs across the supply chain with a broad product offering that includes full-service truck leasing, truck rental, and contract maintenance along with logistics services, such as dedicated contract carriage, distribution center management, freight management, and dry van truckload carrier services. We recorded $198.0 million and $289.5 million in equity earnings from this investment in 2024 and 2023, respectively, and during 2024 and 2023, we received $98.4 million and $168.8 million, respectively, of pro rata cash distributions relating to this investment.

Outlook

Retail Automotive. During 2024, U.S. industry new light vehicle sales increased 2.5%, to 16.0 million units, including a 3.0% increase in retail sales, partially offset by a 2.5% decrease in fleet sales, as compared to 2023. U.K. new vehicle registrations increased 2.6% to 2.0 million registrations, including an 11.8% increase in fleet sales, partially offset by an 8.7% decrease in retail sales, as compared to 2023. New vehicle sales are being positively impacted by continued strong consumer demand in the U.S. and manufacturer incentives. Government incentives on electric vehicles ("EVs") also impact vehicle sales. Our new vehicle days' supply is 49 as of December 31, 2024, compared to 39 as of December 31, 2023, including vehicles which are unable to be sold due to open recalls. Our used vehicle days' supply is 47 as of December 31, 2024, compared to 48 as of December 31, 2023, and is being impacted by a lower supply of 1-4 year old used vehicles as a result of the lower number of new vehicles sold in recent years and fewer lease returns in the U.S. As a reference, our new and used days' supply was 71 and 52, respectively, as of December 31, 2019 (pre-COVID). According to the National Automobile Dealers Association, sales for the U.S. light vehicle market are expected to grow to 16.2 million units in 2025 compared to a 16.0 million market in 2024.

As the supply of new vehicles has improved, we have experienced, and may continue to experience, reduced new and used vehicle gross profit. The regulatory authorities in our markets have adopted emissions limits on new vehicles which are designed to incent adoption of electric or other zero-emissions vehicles. We believe there is a direct correlation between the availability of government incentives for EVs and EV sale levels. New vehicle sales levels could be impacted by changes to these regulatory mandates as well as vehicle affordability challenges, inflation, interest rates, or a reduction in consumer spending resulting in decreased demand. The unavailability of 1-4 year old quality, low-mileage used vehicles for sale may adversely impact our used vehicle operations.

Representatives of the U.K. government have proposed a ban on the sale of internal combustion engines in new cars and new vans that may take effect as early as 2030 while also providing government incentives on certain EVs to entice consumers to transition from internal combustion vehicles to EVs. In part due to these incentives, U.K. new registrations of EVs, excluding hybrid, represented 19.6% of the overall market during 2024, as compared to 16.5% during 2023, and represented 24.3% of our U.K. new unit sales, as compared to 22.4% during 2023. U.K. new registrations of hybrid vehicles represented 21.9% of the overall market during 2024, as compared to 20.0% during 2023, and represented 13.2% of our U.K. new unit sales, as compared to 11.9% during 2023. In the U.S., sales of EVs increased 7.3% to 1.3 million units as compared to 2023. EV sales (excluding hybrid) represented 8.1% of the overall U.S. market during 2024, as compared to 7.7% during 2023. In the U.S., sales of hybrid vehicles were 1.9 million units in 2024 as compared to 1.2 million units in 2023. EV sales may increase or decrease in our markets as a result of government policy, manufacturer incentives, and consumer acceptance of vehicle range or vehicle charging infrastructure. During 2024, 4.2% of new vehicle sales in the U.S., and 2.6% of the new vehicle sales in the U.K., were sold by vehicle manufacturers directly to consumers outside of the retail automotive franchised system, principally consisting of one manufacturer. We expect continued strong demand for our service and parts operations driven by increases in demand in light of increasing vehicle sales in recent years, recall campaigns, increased miles driven, and vehicle complexity.

Retail Commercial Truck Dealership. During 2024, North American sales of Class 6-8 medium- and heavy-duty trucks, the vehicles sold by our PTG business, decreased 3.0% from last year to 473,159 units, primarily due to increased deliveries in 2023 as a result of deliveries expected in 2022 being delayed into 2023 due to supply constraints as well as continued lower freight rates in the U.S. The Class 6-7 medium-duty truck market increased 0.5% from last year to 157,260 units, and Class 8 heavy-duty trucks, the largest North American market, decreased 4.7% from last year to 315,899 units. We expect replacement demand to continue in 2025, although a continued weak freight market may impact unit sales and service and parts demand. As of December 31, 2024, the Class 6-8 medium- and heavy-duty truck backlog is 213,366 units according to data published by ACT Research compared to 278,616 as of December 31, 2023. See Item 1. Business, "Retail Commercial Truck Dealership Operations."

Commercial Vehicle Distribution and Other. During 2024, the Australian heavy-duty truck market reported sales of 17,153 units, representing a decrease of 2.4% from last year, while the New Zealand market reported sales of 3,439 units, representing a decrease of 13.7% from the same period last year. Our power system operations continue to grow through sales in the off-highway segments such as energy solutions, which provide power systems for large data centers, mining, and military applications.

Penske Transportation Solutions. A majority of PTS' revenue is generated by multi-year contracts for full-service leasing, contract maintenance, and logistics services. PTS also rents additional trucks to commercial customers in response to demand for freight as well as consumer customers. With a managed fleet of over 435,000 vehicles at December 31, 2024, PTS regularly sells trucks in order to maintain a low fleet age as well as in response to changes in demand for truck leasing and records a gain or loss on those sales. PTS is currently experiencing positive revenue growth in its business despite adverse global economic freight conditions. This growth is being driven by its full-service leasing, contract maintenance and logistics businesses, partially offset by lower revenues in its commercial and consumer rental product lines. The weaker freight environment and higher interest rates have directly impacted demand for its transactional products as well as used vehicle pricing. PTS has decreased, and expects to continue to decrease, the size of its consumer and commercial rental fleets in connection with this lower demand, aimed at improving the utilization rate of the fleet. PTS further anticipates that these market conditions will continue through 2025, and possibly longer, before improving. Additionally, increased market interest rates compared to prior years have resulted in meaningful increases to its interest expense, both in its variable rate indebtedness and as it refinances existing fixed rate indebtedness, while lower average selling prices for used trucks has resulted in a meaningful decrease in gain on sale from remarketing activities.

As described in Item 1A. Risk Factors, there are a number of factors that could cause actual results to differ materially from our expectations. For a detailed discussion of our financial and operating results, see Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Diversification

Our business benefits from a diversified revenue and gross profit mix, including multiple revenue and gross profit streams in our traditional vehicle and commercial truck dealerships (new vehicles, used vehicles, finance and insurance, and service and parts operations) across many geographies, our commercial vehicle distribution and power systems operations, and returns relating to our joint venture investments, which we believe helps to mitigate the cyclicality that has historically impacted some elements of the automotive sector. Furthermore, PTG provides diversification both by business line and by its business being represented across the U.S. and in Canada. Finally, our ownership interest in PTS provides us with additional diversification as well as equity earnings, cash dividends, and significant cash savings on taxes.

We are also diversified geographically as established by the following table, which shows our consolidated revenue and gross profit by country as a percentage of our total revenue and total gross profit:

Country % of Total 2024 Revenue % of Total 2024 Gross Profit

United States 58 % 61 %

United Kingdom 31 % 27 %

Germany/Italy 5 % 5 %

Japan 1 % 1 %

Canada 2 % 2 %

Australia/New Zealand 3 % 4 %

We are also diversified within our automotive retail operations by brand. We represent over 40 brands in our markets and our automotive dealership revenue mix consists of 72% related to premium brands, 21% related to volume non-U.S. brands, 2% related to brands of U.S. based manufacturers, and 5% related to our used vehicle dealerships as further detailed in the chart below:

New Vehicle Retail Sales. In 2024, we retailed, including agency units, more than244,990 new vehicles which generated 46.1% of our retail automotive dealership revenue and 27.0% of our retail automotive dealership gross profit. We strive to maintain outstanding relationships with the automotive manufacturers based in part on our long-term presence

Table of Contents

in the retail automotive market, our commitment to providing premium facilities, our commitment to drive customer satisfaction, the reputation of our management team, and the consistent sales volume at our dealerships. Our dealerships finance the purchase of most new vehicles from the manufacturers through floor plan financing provided primarily by various manufacturers' captive finance companies.

Used Vehicle Retail Sales. In 2024, we retailed 246,608 used vehicles, which generated 33.5% of our retail automotive dealership revenue and 10.7% of our retail automotive dealership gross profit. We acquire used vehicles from various sources, including trade-ins from consumers in connection with their purchase of a new or used vehicle from us, purchases of used vehicles directly from consumers, lease expirations, public auctions, and auctions open only to authorized new vehicle dealers. To improve customer confidence in our used vehicle inventory, we provide vehicle history reports for all used vehicles, and virtually all of our franchised new vehicle dealerships participate in manufacturer certification processes for used vehicles. If certification is obtained, the used vehicle owner is typically provided benefits and warranties similar to those offered to new vehicle owners by the applicable manufacturer.

Vehicle Finance and Insurance Sales. Finance and insurance sales represented 3.1% of our retail automotive dealership revenue and 19.1% of our retail automotive dealership gross profit in 2024. At our customers' option, our dealerships can arrange third-party financing or leasing in connection with vehicle purchases. We typically receive a flat fee or a portion of the cost of the financing or leasing paid by the customer for each transaction. While these services are generally non-recourse to us, we are subject to chargebacks in certain circumstances, such as default under a financing arrangement or pre-payment. These chargebacks vary by finance product but typically are limited to the fee we receive.

We also offer our customers various vehicle warranty and extended protection products, including extended service contracts, maintenance programs, and voluntary vehicle protection products. The extended service contracts and other products that our dealerships currently offer to customers are underwritten by independent third parties, including the vehicle manufacturers' captive finance companies. Similar to finance transactions, we are subject to chargebacks relating to fees earned in connection with the sale of certain protection products. We also offer for sale other aftermarket products, including security systems and protective coatings.

We offer finance and insurance products using a "menu" process, which is designed to ensure that we offer our customers a complete range of finance, insurance, protection, and other aftermarket products in a transparent manner. We utilize docuPAD® at our U.S. dealerships, an interactive electronic interface designed to improve document processing and menu presentation of finance and insurance options during the purchase or lease transaction.

Service and Parts Sales. Service and parts sales represented 11.7% of our retail automotive dealership revenue and 41.7% of our retail automotive dealership gross profit in 2024. We generate service and parts revenue in connection with providing a wide range of services such as vehicle maintenance, cosmetic repair, manufacturer recalls, warranty, out-of-warranty, rapid repair, and collision repair services. We also recondition used vehicles that we intend to sell in our dealerships. We look to generate higher revenue by driving higher levels of customer satisfaction, marketing, and the use of technology such as videos which allow our technicians to interact directly with the customer, obtain digital approvals, and increase efficiency. Additionally, our AI-driven service scheduling and reception system at certain of our dealerships enhances the customer experience by providing instant support, reducing wait times, and offering 24/7 assistance, enabling seamless service even outside regular hours. By accurately interpreting customer needs and automating appointment bookings, the system streamlines operations, allowing staff to focus on more complex tasks while providing customers with access to human support when necessary. We also believe our service and parts revenues benefit from the increasingly complex technology built into vehicles today. We believe this offers an advantage to our automotive dealerships as the complexity makes it increasingly difficult for independent repair shops and do-it-yourself enthusiasts to maintain and repair today’s vehicles, including the components and systems used in battery and hybrid EVs. We also offer rapid repair services, such as paintless dent repair, tire sales, and windshield replacement at most of our facilities in order to offer our customers the convenience of one-stop shopping for all of their automotive requirements.

We also operate 36 automotive collision repair centers, each of which is operated as an integral part of our dealership operations. The collision centers are staffed with factory-certified technicians with broad capabilities, extending to complete vehicle reconstruction and mechanical engine repairs. Our collision centers also carry an extensive inventory of parts for the new and used vehicles they repair.

Fleet and Wholesale Sales. Fleet and wholesale sales represented 5.6% of our retail automotive dealership revenue and 1.5% of our retail automotive dealership gross profit in 2024. Fleet activities represent the sale of new units to customers that are deemed to not be retail customers, such as cities, municipalities, or rental car companies and are generally sold at

contracted amounts. Wholesale activities relate to the sale of used vehicles generally to other dealers and occur at auction. In the U.K., we offer used vehicles to wholesalers and other dealers via a proprietary online auction.

Retail Commercial Truck Dealership Operations

Premier Truck Group (“PTG”) is a heavy- and medium-duty truck dealership group offering primarily Freightliner and Western Star trucks (both Daimler brands) with 45 locations across 10 U.S. states and the Canadian provinces of Ontario and Manitoba. PTG dealerships provide a similar suite of services as our automotive dealerships, offering new trucks and a large selection of used trucks for sale, a full range of parts, maintenance and repair services, collision centers, and finance and insurance options by facilitating truck and trailer financing and leasing, extended maintenance plans, voluntary vehicle protection products, and other programs.

The maintenance and repair of commercial trucks is an essential service and a key area of differentiation for our business. We offer “Elite Support” certified locations to help maximize vehicle uptime. Elite Support certified locations provide an express assessment whereby we communicate a primary diagnosis, check parts availability, and provide an estimate of cost and repair time within a few hours of service write-up. As part of this service, many of our locations offer a comfortable environment for customers with amenities such as customer lounges, lockers, showers, and laundry facilities. We also offer roadside remote service for certain repairs and provide 24/7 technician support for breakdown/emergency service in select locations.

The collision centers at PTG are full-service, heavy-duty paint and collision repair facilities with certified professionals that can handle everything from light cosmetic issues to complete vehicle reconstruction, including mechanical engine repairs. PTG also carries an extensive inventory of parts for the new and used trucks they sell and service. The service and parts business of our PTG commercial truck dealerships represents approximately 65% of our retail commercial truck dealership gross profit.

A significant portion of our new commercial vehicle sales are to customers with large fleets of commercial vehicles. Because of the size and geographic scope of our dealership locations, our strong relationships with our fleet customers and our ability to manage large quantities of used commercial vehicle trade-ins, we are able to successfully market and sell to large fleet customers. We believe that we have a competitive advantage over many dealerships because we can absorb multi-unit trade-ins often associated with fleet sales and effectively disperse the used commercial vehicles for resale throughout our dealership network. We believe that the broad range of products and services we offer to purchasers of commercial vehicles at the time of purchase and post-purchase results in a high level of customer loyalty.

Backlog is a key industry metric for commercial vehicle retailers. Backlog is the number of new commercial vehicles ordered by customers, however, such orders are subject to cancellation. In the event of order cancellation, retailers generally have no contractual right to require the customer to purchase the vehicle. The delivery time for a customer ordered commercial vehicle varies depending on the truck specifications and demand for the model ordered. We sell the majority of our new heavy-duty commercial vehicles by customer special order and we sell the majority of our medium duty commercial vehicles out of inventory. As of December 31, 2024, the Class 6-8 medium- and heavy-duty truck backlog is 213,366 units according to data published by ACT Research compared to 278,616 at December 31, 2023.

Fixed Absorption Ratio. We believe the fixed absorption ratio is useful to investors as it improves the transparency of our disclosures and provides a meaningful metric evidencing the impact of our commercial truck businesses' parts and service operations on PTG's overall operating profitability. Our fixed absorption ratio is calculated by dividing PTG's gross profit from our parts and service departments by PTG's total overhead expenses, except for the variable selling expenses of the new and used commercial vehicle departments, advertising expense, and carrying costs of new and used commercial vehicle inventory. Our commercial truck dealerships achieved a 125.0% fixed absorption ratio for 2024, compared to a 129.2% fixed absorption ratio for 2023.

Commercial Vehicle Distribution and Other Operations

Penske Australia. Penske Australia is the exclusive importer and distributor of Western Star heavy-duty trucks (a Daimler brand), MAN heavy- and medium-duty trucks and buses (a VW Group brand), and Dennis Eagle refuse collection vehicles, together with associated parts, across Australia, New Zealand, and portions of the Pacific.

Penske Australia distributes commercial vehicles and parts for Western Star, MAN, and Dennis Eagle to a network which comprises on average of more than 70 dealership locations across Australia, New Zealand, and portions of the Pacific. Of these dealership locations, 12 are company-owned retail commercial vehicle and/or service and parts dealerships in Australia and three are company-owned retail commercial vehicle dealerships in New Zealand.

Western Star trucks are manufactured by Daimler Trucks North America in Portland, Oregon. These technologically advanced, custom-built vehicles are ordered by customers to meet their particular needs for line haul, long distance road train, mining, logging, and other heavy-duty applications. We are also the exclusive importer of MAN trucks and buses. MAN Truck and Bus, a VW Group company, is a leading producer of medium- and heavy-duty trucks as well as city and coach buses. These cab-forward, fuel efficient vehicles are principally produced in several sites in Germany and are ordered by customers for line haul, local distribution, mining, and other off-road applications. Dennis Eagle refuse collection vehicles are manufactured by Ros Roca in Warwick, England. These brands represented 4.1% of heavy-duty truck units sold in Australia and 2.0% in New Zealand during 2024.

We also distribute diesel gas engines and power systems to over 100 dealer locations that are strategically located throughout Australia, New Zealand, and portions of the Pacific. Most of the dealers represent the Detroit Diesel brand, with the majority aligned to Western Star and/or Freightliner truck manufacturers. The remaining dealers represent the MTU and Allison Transmission brands. The “off-highway” business principally includes the sale and servicing of power systems directly to customers in the commercial, defense, mining, maritime, power generation, and energy solutions sectors from 20 facilities we operate across Australia and New Zealand. We also utilize mobile remote field service units to travel directly to customer premises.

Penske Transportation Solutions

We hold a 28.9% ownership interest in Penske Truck Leasing Co., L.P. (“PTL”). Penske Transportation Solutions (“PTS”) is the universal brand name for PTL's various business lines through which it is capable of meeting customers' needs across the supply chain with a broad product offering that includes full-service truck leasing, truck rental, and contract maintenance along with logistics services, such as dedicated contract carriage, distribution center management, freight management, and dry van truckload carrier services. PTS has a highly diversified customer base ranging from multi-national corporations across industries, such as food and beverage, transportation, manufacturing, automotive, retail, and healthcare, with whom they have long-term contracts to individual consumers who rent a single truck on a daily basis.

PTS manages one of the largest, most comprehensive and modern trucking fleets in North America, with approximately 435,000 trucks, tractors and trailers under lease, rental and/or maintenance contracts as of December 31, 2024, through their network of locations throughout North America. Furthermore, PTS has consistently been among the largest purchasers of commercial trucks in North America and had an average full-service leasing Class 8 tractor fleet age of approximately 3.4 years as of December 31, 2024, which is substantially lower than the overall Class 8 tractor fleet age in the United States.

Full-service truck leasing, truck rental, and contract maintenance.Full-service truck leasing, truck rental, and contract maintenance of commercial trucks, tractors, and trailers constitutes PTS' largest business. PTS manages a fleet of over 435,000 trucks, tractors, and trailers, consisting of over 282,900 vehicles owned by PTS and leased to customers under full-service lease or rental agreements and over 152,300 customer-owned and -operated vehicles for which they provided contract maintenance services. Lease terms under its full-service leases generally range from four to seven years for tractors and trucks and six to twelve years for trailers. Its commercial and consumer rental fleet as of December 31, 2024, consisted of approximately 94,800 vehicles for use by its full-service truck leasing, small business, and consumer customers for periods generally ranging from less than a day to 12 months. Most of its leased vehicles are configured according to customer specifications, including custom painting and lettering, while its rental trucks bear Penske branding.

Commercial customers often outsource to PTS to reduce the complexity, cost, and total capital associated with vehicle ownership. Under a full-service lease, PTS provides and fully maintains the vehicle, which is generally configured for the customer. The services provided under full-service lease and contract maintenance agreements generally include preventive and regular maintenance, advanced diagnostics, emergency road service, fleet services, safety programs, and fuel services through PTS' network of company-operated facilities and a nationwide network of independent truck stops. In addition, PTS makes available to its full-service leasing and contract maintenance customers additional vehicles on a rental basis. PTS' commercial rental operations offer short-term availability of tractors, trucks, and trailers typically to accommodate seasonal, emergency, and other temporary needs. A significant portion of these rentals are to existing full-service leasing and contract maintenance customers who are seeking flexibility in their fleet management. PTS has established a network of approximately 930 locations to provide full-service truck leasing, truck rental, and contract maintenance services to

customers. This network enables PTS to meet multi-location customer requirements. PTS' commercial rental business generated 19% of its revenue for 2024 and its full-service lease and contract maintenance business generated 50% of its revenue in 2024.

For consumer customers, PTS provides short-term rental of light- and medium-duty vehicles on a one-way and local basis, typically to transport household goods. Customers typically include local small businesses and individuals seeking a do-it-yourself solution to their moving needs. PTS' consumer fleet generally consists of late model vehicles ranging in size from small vans to 26-foot trucks, and its consumer rentals are conducted through approximately 1,910 independent rental agents and approximately 410 of its company-operated leasing and rental facilities. PTS' consumer business generated 3% of its revenue for 2024.

Logistics. PTS' logistics business offers an extensive variety of services, including dedicated contract carriage, distribution center management, freight management, lead logistics provider, and dry van truckload carrier services. PTS coordinates services for its customers across the supply chain, including inbound material flow, handling and packaging, inventory management, distribution and technologies, and sourcing of third-party carriers. These services are available individually or on a combined basis and often involve its associates performing services at the customer's location. By offering a scalable series of services to its customers, PTS can manage the customer's entire supply chain or any stand-alone service. PTS also utilizes specialized software that enables real-time fleet visibility and provides reporting metrics, giving customers detailed information on fuel economy and other critical supply chain costs. PTS' international logistics business has approximately 520 locations in North America, South America, and Europe. PTS' logistics business generated 28% of its revenue for 2024.

Industry Information

Retail Automotive. Approximately 56% of our retail automotive dealership revenues are generated in the U.S. and Puerto Rico, which in 2024 was one of the world's largest automotive retail markets as measured by units sold. In 2024, sales of new cars and light trucks were approximately 16.0 million units, an increase of 2.5% from 2023, and were generated at approximately 16,900 franchised new-car dealerships. According to data from the National Automobile Dealers Association, dealership revenue is generally derived as follows: 54% from new vehicle sales, 33% from used vehicle sales (in each case including related finance and insurance revenues), and 13% from service and parts sales.

In the U.S., the franchised automotive dealer industry is one of the largest retail businesses by revenue in a market of approximately $1.2 trillion. Although significant consolidation has already taken place, the industry remains highly fragmented with approximately 90% of the U.S. industry's market share remaining in the hands of smaller regional and independent dealers. Our other markets are similarly fragmented. We believe that further consolidation in these markets is probable due to the significant capital requirements of maintaining manufacturer facility standards and the limited number of viable alternative exit strategies for dealership owners.

Our international automotive retail dealerships operate in the U.K., the European Union, Japan, and Australia. In the U.K., new vehicle registrations in 2024 totaled 1.95 million, which increased 2.6% from 1.90 million new vehicle registrations in 2023. Our European Union markets consist of Germany, Italy, and Spain, which represented the first, third, and fourth largest automotive retail markets, respectively, in the European Union in 2024 and accounted for approximately 51% of the total vehicle sales in the European Union markets. Unit sales of automobiles in the European Union were approximately 10.6 million in 2024, a 0.8% increase compared to 2023. In Germany, Italy, and Spain, new car sales were approximately 2.8 million, 1.6 million, and 1.0 million units, respectively, in 2024, new car sales in Japan were approximately 4.4 million in 2024, and new car sales in Australia were approximately 1.2 million in 2024.

As of December 31, 2024, we also operated 16 used vehicle dealerships. Used vehicle sales are even more fragmented than new vehicle sales and are generated by new car dealerships, used vehicle dealerships, individual small lot sellers, as well as individual to individual sales. In 2024, used vehicle sales were approximately 36.8 million units in the U.S. according to data from Cox Automotive, compared to 35.9 million in the prior year, and approximately 7.6 million units in the U.K. according to data from the Society of Motor Manufacturers and Traders, compared to 7.2 million in the prior year.

Retail Commercial Truck Dealership. The retail heavy-duty truck market is affected by a number of factors, including general economic conditions, fuel prices, other methods of transportation, environmental and other government regulation, interest rate fluctuations, freight metrics, and customer business cycles. According to data published by ACT Research, in recent years, total U.S. retail sales of new Class 8 commercial vehicles have ranged from a low of approximately 97,000 in 2009 to a high of approximately 334,000 in 2019. Class 8 trucks are defined by the American Automobile Association as trucks with a minimum gross vehicle weight rating above 33,000 pounds. Typically, Class 8 trucks are assembled by manufacturers utilizing certain components that may be manufactured by other companies, including engines,

10

Table of Contents

transmissions, axles, wheels and other components. As commercial vehicles and certain commercial vehicle components have become increasingly complex, the ability to provide service for commercial vehicles has become an increasingly competitive factor in the industry. The ability to provide such service requires a significant capital investment in diagnostic and other equipment, parts inventory and highly trained service personnel. The EPA and Department of Transportation regulatory guidelines for service processes, including collision center, paint work and waste disposal, require sophisticated equipment to ensure compliance with environmental and safety standards. In 2024, North American sales of Class 6-8 medium- and heavy-duty trucks, the principal vehicles sold by our PTG business, decreased 3.0% from last year to 473,159 units and were generated at approximately 3,800 new-truck dealerships. The Class 6-7 medium-duty truck market increased 0.5% from last year to 157,260 units, and Class 8 heavy-duty trucks, the largest North American market, decreased 4.7% from last year to 315,899 units. Our principal brands, Freightliner and Western Star, represent approximately 42.9% of the Class 8 heavy-duty truck market during 2024.

Commercial Vehicle Distribution and Other. Our commercial vehicle distribution and other business operates principally in Australia and New Zealand. In 2024, heavy-duty truck sales in Australia and New Zealand combined were 20,592 units, representing a decrease of 4.5% from 2023. The brands we sell represented 4.1% of the heavy-duty truck units sold in Australia and 2.0% in New Zealand during 2024.

Penske Transportation Solutions. PTS participates broadly in the global supply chain, estimated at $11.2 trillion annually, and particularly, in the U.S. supply chain, estimated at $2.3 trillion annually. Only 13.2% of the total U.S. supply chain function is outsourced to third parties, such as PTS. We estimate, based on R. L. Polk registration data, that there are approximately 9.6 million commercial trucks operating in the United States and Canada, of which up to 5.0 million could be potential opportunities for PTS' full-service leasing and contract maintenance offerings.

Business Description

Marketing Strategy

Our integrated marketing strategies empower each dealership to capitalize on local branding while being supported by corporate programs and web presence, allowing us to leverage scale. We align ourselves with the marketing implemented by our vehicle manufacturer partners for their respective brands and integrate those initiatives and resources across the brands we represent.

We are focused on executing a comprehensive data-driven digital strategy with emphasis on customization, personalization, and creating a connection with our customers. We endeavor to build and optimize our presence across all digital platforms and deliver a seamless, convenient, and transparent experience that gives customers the ability to purchase, sell, or schedule service for their vehicles on their terms.

To stay at the forefront of technological innovations, we leverage software and systems to support our customers regardless of how they want to engage with us, from fully online to in-person or anywhere in between. In addition, we have implemented AI-driven technologies at certain of our dealerships, including a voice assistant to answer and appoint inbound service calls and an engagement system to address customer lead inquiries and schedule sales and service appointments. These technologies are designed to improve our customer experience and allow customers to engage with us 24/7.

We monitor customer satisfaction data to gain insight into our business performance and enhance the areas of our business that drive customer referral and loyalty. Social media is a highly valued element of our marketing strategy that enables us to engage with customers, increase dealership awareness, improve customer satisfaction, and enhance repeat and referral business. Additionally, we leverage corporate social media efforts and partners to benefit our dealerships and create a strong sense of community. Online reputation management sites are proactively monitored to ensure we are offering superior customer experience.

Agreements with Vehicle and Equipment Manufacturers

We operate our new vehicle dealerships under separate agreements with the manufacturers or distributors of each brand of vehicle sold at that dealership. These agreements are typical throughout the industry and may contain provisions and standards governing almost every aspect of the dealership including ownership, management, personnel, training, maintenance of a minimum of working capital, net worth requirements, maintenance of minimum lines of credit, advertising and marketing activities, facilities, signs, products and services, maintenance of minimum amounts of insurance, achievement of minimum customer service standards, and monthly financial reporting. In addition, the General Manager and/or the owner of a dealership typically cannot be changed without the manufacturer's consent. In exchange for

11

Table of Contents

complying with these provisions and standards, we are granted the non-exclusive right to sell the manufacturer's or distributor's brand of vehicles and related parts and warranty services at our dealerships. The agreements also grant us a non-exclusive license to use each manufacturer's trademarks, service marks, and designs in connection with our sales and service of its brand at our dealership.

Many of these agreements also grant the manufacturer or distributor a security interest in the vehicles and/or parts sold by them to the dealership as well as other dealership assets and permit them to terminate or not renew the agreement for a variety of causes, including failure to adequately operate the dealership, insolvency or bankruptcy, impairment of the dealer's reputation or financial standing, changes in the dealership's management, owners, or location without consent, sales of the dealership's assets without consent, failure to maintain adequate working capital or floor plan financing, changes in the dealership's financial or other condition, failure to submit required information to them on a timely basis, failure to have any permit or license necessary to operate the dealership, and material breaches of other provisions of the agreement. In the U.S., these termination rights are subject to state franchise laws that limit a manufacturer's right to terminate a franchise. In the U.K., we operate without such local franchise law protection (see “Regulation” below).

In the U.S., some of our franchise agreements, including those with BMW, Daimler Truck North America, Honda, Hyundai, and Toyota, expire after a specified period of time ranging from one to six years. Manufacturers have not historically terminated our franchise agreements, and our franchise agreements with fixed terms have typically been renewed. We currently expect the manufacturers to renew all of our U.S. franchise agreements as they expire. In the U.K., many of our agreements have two-year rolling terms. Our agreements with BMW, our largest U.K. manufacturer, expire in December 2025. Similar to the U.S., the manufacturers in the U.K. have not historically terminated our agreements, and our agreements with fixed terms have typically been renewed.

In addition, we are subject to certain framework agreements with manufacturers that allow us as a multi-point, public company to own and operate multiple franchises in exchange for us agreeing, among other things, to limit the total number of dealerships of that brand that we may own in a particular geographic area and in some cases, limit the total number of their vehicles that we may sell as a percentage of a particular manufacturer's overall sales. Manufacturers may also limit the ownership of stores in contiguous markets. Certain of our franchise agreements have similar limits. We have reached certain national and regional geographical limitations under the agreements from time to time. Where these limits are reached or we otherwise fail to satisfy certain performance or other conditions specified in the framework agreements, we cannot acquire additional franchises of those brands in the relevant market unless we can negotiate modifications or waivers to the agreements.

These agreements also typically restrict the acquisition of additional dealerships unless the Company’s dealerships of that brand individually and/or in the aggregate are meeting certain requirements. These framework agreements typically provide the manufacturer or distributor the right in some circumstances (including upon a merger, sale, change of control of the Company, or in some cases a material change in our business or capital structure) to acquire the dealerships from us at fair market value or other predetermined values, including upon the acquisition of 20% or more of our voting stock by a person, entity, group, or another manufacturer (subject to certain exceptions), an extraordinary corporate transaction (such as a merger, reorganization, or sale of a material amount of assets), or a change of control of our board of directors. See Item 1A. Risk Factors, "Vehicle manufacturers exercise significant control over us and our success is largely dependent on the success of our manufacturer partners."

With respect to our commercial vehicle distribution and other operations in Australia and New Zealand, we are party to distributor agreements with each manufacturer of products we distribute pursuant to which we are the distributor of these products in those countries and nearby markets. The agreements govern all aspects of our distribution rights, including sales and service activities, service and warranty terms, use of intellectual property, promotion and advertising provisions, pricing and payment terms, and indemnification requirements. The agreement with Western Star expires in 2031, the agreement with MTU expires in 2029, and the agreement with Detroit Diesel expires in 2031. We also are party to shipping agreements with respect to importing those products. For each of our non-company-owned dealers, we have signed a franchise agreement with terms that set forth the dealer's obligations with respect to the sales and servicing of commercial vehicles and associated parts.

Competition

Dealerships.We believe that the principal factors consumers consider when determining where to purchase a vehicle are vehicle pricing (including manufacturer rebates and other special offers), marketing campaigns conducted by manufacturers, the ability of dealerships to offer a wide selection of the most popular vehicles, offering a multi-channel experience to customers so they may purchase a vehicle on site or remotely, the location of dealerships, and the quality of

12

Table of Contents

the customer experience. Other factors include customer preference for particular brands of vehicles and warranties. We believe that our dealerships are competitive in all of these areas.

The automotive and truck retail industry is currently served by franchised or agency dealerships, automotive manufacturers that sell directly to consumers, independent used vehicle dealerships, and individual consumers who sell used vehicles in private transactions. For new vehicle sales, we compete primarily with other franchised dealers in each of our marketing areas and automotive manufacturers that sell directly to consumers, relying on our premium facilities, superior customer service, advertising and merchandising, management experience, sales expertise, reputation, and the location of our dealerships to attract and retain customers. Each of our markets may include a number of well-capitalized competitors, including in certain instances dealerships owned by manufacturers and national and regional retail chains. In our retail commercial truck dealership operations, we compete with other manufacturers and retailers of medium- and heavy-duty trucks, such as Ford, International Kenworth, Mack, Peterbilt, and Volvo. We also compete with dealers that sell the same brands of new vehicles that we sell and with dealers that sell other brands of new vehicles that we do not represent in a particular market. Our new vehicle dealership competitors have franchise agreements which give them access to new vehicles on the same terms as us. Automotive dealers also face competition in the sale of new vehicles from purchasing services, and electric vehicle manufacturers that sell directly to consumers. With respect to arranging financing for our customers' vehicle purchases, we compete with a broad range of financial institutions, such as banks and local credit unions.

For used vehicle sales, we compete in a highly fragmented market which sells approximately 36.8 million units in the U.S. and approximately 7.6 million units in the U.K. annually through other franchised dealers, independent used vehicle dealers, automobile rental agencies, purchasing services, private parties, online retailers, and used vehicle “superstores” for the procurement and resale of used vehicles.

We compete with other franchised dealers to perform warranty repairs and with other dealers, franchised and non-franchised service center chains, and independent garages for non-warranty repair and routine maintenance business. We compete with other dealers, franchised and independent aftermarket repair shops, and parts retailers in our parts operations. We believe that the principal factors consumers consider when determining where to purchase vehicle parts and service are price, the use of factory-approved replacement parts, facility location, the familiarity with a manufacturer's brands, and the quality of customer service. A number of regional or national chains offer selected parts and services at prices that may be lower than our prices.

We believe the majority of consumers are utilizing the Internet and other digital media in connection with the purchase of new and used vehicles. Accordingly, we face increased competition from online vehicle websites, including those developed by manufacturers and other dealership groups.

Commercial Vehicle Distribution and Other. With respect to our commercial vehicle distribution and other operations in Australia and New Zealand, we compete with manufacturers, distributors, and retailers of other vehicles and products in our markets.

PTS.As an alternative to using PTS' full-service truck leasing or contract maintenance services, we believe that most potential customers perform some or all of these services themselves. They may also purchase similar or alternative services from other third-party vendors. Its full-service truck leasing operations compete with companies providing similar services on a national, regional, and local level. Many regional and local competitors provide services on a national level through their participation in various cooperative programs. Competitive factors include price, maintenance, service, and geographic coverage. PTS competes with finance lessors, truck and trailer manufacturers, and independent dealers, each of which provides full-service lease products, finance leases, extended warranty maintenance, rental, and other transportation services. Its contract maintenance offering competes primarily with truck and trailer manufacturers and independent dealers who provide maintenance services.

PTS' commercial and consumer rental operations compete with several other nationwide vehicle rental systems, a large number of vehicle leasing, and rental companies with multiple branches operating on a regional basis and many similar companies operating primarily on a local basis. Because a significant portion of its consumer rentals are used for moving and relocation, PTS competes with local and national moving and storage companies as well as alternatives such as portable container-based transportation and storage. In its commercial and consumer rental operations, it competes primarily on the basis of equipment availability, geographic location, and customer service.

PTS' logistics business competes with other dedicated logistics providers, freight management businesses, freight brokers, warehouse providers, and truckload carriers on a national, regional, and local level as well as with the internal supply chain functions of prospective customers who rely on their own resources for logistics management. Competitive

13

Table of Contents

factors include price, efficient logistical design offerings, equipment, maintenance, service, technology, geographic coverage, and driver and operations expertise. PTS seeks to combine its logistics services with its existing full-service truck leasing and truck rental business to create an integrated transportation solution for its customers.

Human Capital

We believe that our Human Capital is our greatest asset and is an integral component of our growth and value creation strategy. We understand that exceptional customer service can only be consistently delivered by attracting, motivating, training, and retaining the very best team members. We strive to provide a work environment that promotes opportunity and is free from any form of discrimination based on any protected status in accordance with all applicable federal, state, and local laws. With this in mind, we put our employees at the heart of everything that we do by developing their talent and enabling them to build long-term careers.

In recognition of our people-first philosophy, in 2024, 79of our dealerships were named to the "Automotive News Best Dealerships To Work For", which ranks the top 150 dealerships in the United States, including nine of the top ten spots and 17 of the top 20 spots nationally in 2024's rankings with one of our dealerships claiming the number one spot, more than any other dealership group. Our dealerships were also recognized for their commitment to promoting inclusive workplaces, receiving accolades for being among the best in the following categories: Best Dealerships for Employees 30 or Younger; Best Dealerships for Diversity, Equity and Inclusion; Best Dealerships for Minority Leadership; Best Dealerships for Family Friendliness. PTG was also named as one of the 2024 "Top Companies for Women to Work in Transportation." Also, in January 2024, we were notified that Penske Automotive Group was named by Fortune as a "World's Most Admired Company".

As of December 31, 2024, we employed approximately 28,900 people, of which approximately 683 were covered by collective bargaining agreements with labor unions. We believe our relations with our employees, including those represented by collective bargaining agreements, are generally good. We believe our inclusive culture enhances our ability to attract and retain the most talented leadership and workforce, thereby enabling us to better serve and broaden our customer base.

We maintain a culture grounded in safety and endeavor to eliminate workplace incidents, risks, and hazards. We have partnered with environmental and safety consulting firms to assist in compliance with specific local and federal laws and regulations relating to environmental and safety issues and to promote best safety practices. Audits are regularly performed to ensure and maintain compliance.

We believe our employee turnover of approximately 20% is below the industry averages for our businesses. We seek to motivate our key managers and salespersons through, among other things, variable compensation programs tied principally to local profitability and customer satisfaction. We also annually survey our employees to gauge their satisfaction and address any resulting concerns.

Regulation

We operate in a highly regulated industry and a number of regulations affect the marketing, selling, financing, servicing, and distribution of vehicles. Under the laws of the jurisdictions in which we currently operate, we typically must obtain a license in order to establish, operate, relocate a dealership, or operate a repair facility. These laws also regulate our business conduct, including our advertising, operating, financing, employment, distribution, and sales practices. Other laws and regulations include franchise laws and regulations, environmental laws and regulations (see “Environmental Matters” below), laws and regulations applicable to new and used motor vehicle dealers as well as customer and employee privacy, identity theft prevention, wage-hour, anti-discrimination, and other employment practices laws. With respect to online sales, many laws and regulations applicable to our business were adopted prior to the introduction of the Internet, certain digital technologies, and e-commerce, generally. As a result, we are tasked with maintaining compliance in an uncertain regulatory environment.

Our financing activities with customers are subject to truth-in-lending, consumer leasing, equal credit opportunity, and similar regulations as well as motor vehicle finance laws, installment finance laws, insurance laws, usury laws, and other installment sales laws. Some jurisdictions regulate finance fees that may be paid as a result of vehicle sales. In the U.K., the Financial Conduct Authority (the "FCA") regulates financial services firms and financial markets, including our activities in acting as broker for the financing of vehicle sales. The FCA has announced that it will investigate the historic use of discretionary commission arrangements ("DCAs") amid concerns that this practice may have been unfair to customers. The purpose of the investigation is to consider whether the historic use of DCAs caused customers to pay too much for their car loans and, if so, to consider potential remediation measures. The investigation is being undertaken after the Financial

14

Table of Contents

Ombudsman Service (a public body, which resolves financial complaints) determined that DCAs, in two separate cases which do not involve us, had caused financial losses to customers. We await the outcome of the FCA’s investigation which is expected in May of 2025. Any regulatory or judicial outcome that ultimately results in the refund of historical commissions paid to us or that reduces the commissions paid to us could materially and adversely affect us. Further, on October 25, 2024, the U.K. Court of Appeal (the second highest court in the U.K.) issued a judgment requiring lenders to repay certain customers the commissions paid to dealers for vehicle finance agreements determining that there was a duty to the customers to disclose the amount of the commissions paid to those dealers. Although this judgment has been appealed by the relevant lenders to the U.K. Supreme Court (the highest court in the U.K.), our U.K. consumer lending partners have required that we now disclose to customers the commissions we receive from their vehicle financing. The ultimate resolution of these matters may impact our procedural processes and expose us to claims for repayment of historical commissions. See Item 1A. Risk Factors, "Other Regulatory Issues".

In the U.S., we benefit from the protection of numerous state franchise laws that generally provide that a manufacturer or distributor may not terminate or refuse to renew a franchise agreement unless it has first provided the dealer with written notice setting forth good cause and stating the grounds for termination or non-renewal. Some state franchise laws allow dealers to file protests or petitions or to attempt to comply with the manufacturer's criteria within the notice period to avoid termination or non-renewal. Our international locations generally do not have these laws, and as a result, our international operations operate without these types of protections. See Item 1. Business, "Agreements with Vehicle and Equipment Manufacturers."

Environmental Matters

We are subject to a wide range of environmental laws and regulations, including those governing discharges into the air and water, the operation and removal of aboveground and underground storage tanks, the use, handling, storage, and disposal of hazardous substances and other materials, and the investigation and remediation of environmental contamination. Our business involves the generation, use, handling, and contracting for recycling or disposal of hazardous or toxic substances or waste, including environmentally sensitive materials such as motor oil, filters, transmission fluid, antifreeze, refrigerant, batteries, solvents, lubricants, tires, and fuel. EVs pose additional risks regarding the use, maintenance, and disposal of electric batteries which may be subject to additional regulations. We have incurred, and will continue to incur, capital and operating expenditures and other costs in complying with such laws and regulations.

Our operations involving the management of hazardous and other environmentally sensitive materials are subject to numerous requirements. Our business also involves the operation of storage tanks containing such materials. Storage tanks are subject to periodic testing, containment, upgrading, and removal under applicable law. Furthermore, investigation or remediation may be necessary in the event of leaks or other discharges from current or former underground or aboveground storage tanks. In addition, water quality protection programs govern certain discharges from some of our operations. Similarly, certain air emissions from our operations, such as vehicle painting, may be subject to relevant laws. Various health and safety standards also apply to our operations.

We may have liability in connection with materials that are sent to third-party recycling, treatment, and/or disposal facilities under the U.S. Comprehensive Environmental Response, Compensation, and Liability Act and comparable statutes. These statutes impose liability for investigation and remediation of contamination without regard to fault or the legality of the conduct that contributed to the contamination. Responsible parties under these statutes may include the owner or operator of the site where the contamination occurred and companies that disposed or arranged for the disposal of the hazardous substances released at these sites.

We have a proactive strategy related to environmental, health, and safety compliance, which includes contracting with third parties to inspect our facilities periodically. We believe that we do not have any material environmental liabilities and that compliance with environmental laws and regulations will not, individually or in the aggregate, have a material effect on us. However, soil and groundwater contamination are known to exist at certain of our current or former properties. Further, environmental laws and regulations are complex and subject to change. In addition, in connection with our acquisitions, it is possible that we will assume or become subject to new or unforeseen environmental costs or liabilities, some of which may be material. Compliance with current, amended, new, or more stringent laws or regulations, stricter interpretations of existing laws, or the future discovery of environmental conditions could require additional expenditures by us, and such expenditures could be material.

Vehicle Emissions Regulation

Federal and state governments and regulators in our markets have increasingly placed restrictions and limitations on new vehicles in an effort to combat perceived negative environmental effects. In response to concerns that emissions of

15

Table of Contents

carbon dioxide and certain other gases, referred to as "greenhouse gases" or "GHGs," may be contributing to warming of the Earth's atmosphere, climate change-related legislation and policy changes to restrict GHGs have been implemented at state and federal levels in a manner that impacts our business. The impact of the new U.S. presidential administration on U.S. federal policy in this area is uncertain. See Item 1A. Risk Factors, "Vehicle Emissions and Other Environmental Regulations".

Retail Automotive. Many jurisdictions in which we operate have placed restrictions on new vehicle GHG emissions. The U.S. Environmental Protection Agency ("EPA") has adopted standards that require vehicle manufacturers achieve progressively lower emissions for new vehicles in model years 2027 through 2032. The standards apply to all new light-duty and medium-duty vehicles, which includes passenger vehicles, light trucks and large pickups and vans. The standards require an industry-wide average target for light-duty vehicles of 85 grams of carbon dioxide per mile in model year 2032, a nearly 50% reduction from the 2026 standard. Medium-duty vehicles must achieve a final standard of 274 grams of carbon dioxide per mile by 2032, a 44% reduction from the 2026 standard. The EPA regulates motor vehicle emissions through performance-based standards that impose fleet-wide average emissions limits—individual vehicles with higher emissions are allowable if the fleet average achieves the EPA's emissions targets. The standards do not require the adoption of specific technologies. Automakers may decide which technologies will achieve the standards, such as advanced gasoline engines and transmissions, improvements to tailpipe controls, and electrification. Nonetheless, the EPA projects that the influence of these standards, in conjunction with other market developments like incentives available under the Inflation Reduction Act, will result in plug-in EVs accounting for 68% of new light-duty vehicles by model year 2032.

Moreover, the EPA has allowed the State of California Air Resource Board (“CARB”) to adopt its Advanced Clean Cars II program which requires that new vehicle sales by vehicle manufacturers to be 35% Zero Emissions Vehicles (ZEVs) for model year 2026 which increases to 100% ZEVs by model year 2035 (with certain allowances for hybrid gas/EVs). Certain states have also adopted California’s mandate, in whole or in part.

Some jurisdictions outside the U.S. have implemented similar regulations. The European Parliament requires most automakers to reduce the emissions of new cars sold by 55% in 2030 and achieve a zero carbon-emission standard by 2035, effectively banning the sale of new gasoline and diesel cars and vans by 2035. The U.K. Department for Transport has proposed a ban on the sale of gasoline and diesel engines in new cars that would take effect in as early as 2030 while also providing government incentives on certain EVs to entice consumers to transition from internal combustion vehicles to EVs, although certain reports indicate that the U.K. government may delay the implementation date of these requirements.

Significant increases in fuel economy requirements and new restrictions on emissions of vehicles and fuels could adversely affect prices of and demand for the vehicles that we sell, which could materially adversely affect us. Such vehicles may also not be able to be produced in the quantities required, or, if produced, may not be able to be sold to consumers in light of customer reluctance to transition to EVs. While increasing consumer adoption of EVs may present new service opportunities, including with respect to range maintenance and optimization, cooling protection, torque protection, tire replacement, battery replacement, and warranty on newly released models, our service revenue per vehicle may decline over time as these EVs may require less physical maintenance than gas and hybrid vehicles due to the absence of certain parts systems. However, due to the complexity and training required for the electrical components of the vehicle, we believe a larger percentage of EV customers will be retained for service.

Retail Commercial Truck. Similar regulations apply to the commercial vehicles sold by PTG in the U.S. and Canada and purchased and operated by PTS. The EPA Clean Trucks Plan is designed to incent market shifts to zero-emission technologies in certain segments of the heavy-duty vehicle sector and calls for new more stringent GHG emissions standards for heavy-duty engines and vehicles starting as soon as model year 2027. The first rulemaking under the Clean Trucks Plan was a final rule signed on December 20, 2022, which focuses on reducing emissions that form smog and soot and will apply to heavy-duty engines and vehicles beginning in model year 2027. On March 20, 2024, the EPA published final rules setting new, more stringent, emissions standards for criteria pollutants and GHGs for light-duty and medium-duty vehicles starting in model year 2027 through model year 2032. On March 29, 2024, the EPA published final rules setting more stringent emissions standards for heavy-duty vehicles starting in model year 2027. For example, GHG emissions in light-duty vehicles are required to decrease 49% for model year 2032 as compared to model year 2026. Moreover, beginning with model year 2027, the EPA is requiring electric batteries and related components to have at least an 8-year, 80,000-mile warranty.

Similarly, CARB has adopted performance requirements known as the Advanced Clean Trucks regulation for diesel trucks with periodic compliance dates, and recently set a goal for all heavy-duty trucks in California to be zero emissions by 2045. Some states have followed California in enacting emissions standards and others may choose to do so in the future. For example, several states, including New York, New Jersey, Washington, Oregon, Massachusetts, Colorado and

16

Table of Contents

Vermont, have followed California in adopting an Advanced Clean Trucks regulation, which mandates truck manufacturers who certify Class 2b-8 chassis or complete vehicles with combustion engines to sell zero-emission trucks as an increasing percentage of their annual sales in these states from 2024 to 2035 as well as fleet reporting requirements. In March 2023, CARB was provided a legal waiver by the EPA to require that half of all heavy truck sales be all-electric by 2035. On December 18, 2024, the EPA granted a waiver allowing CARB to implement its Low-NOx Heavy-Duty Omnibus Regulation that, among other things, sets significantly lower NOx and particulate matter emissions standards for model 2024 and later heavy-duty engines and vehicles.

Furthermore, the Advanced Clean Fleet rule, issued by CARB in April 2023, and which may be adopted in other jurisdictions, will require certain larger fleets, including PTS’, to purchase zero-emission trucks to comprise over time an increasing percentage of their fleets from 2025 to 2042. On December 28, 2023, CARB announced that it would defer enforcement of the rule while it requested a waiver from EPA to authorize the rule. In addition, several lawsuits have been filed seeking to invalidate the rule, including by the California Trucking Association, the American Free Enterprise Chamber of Commerce, the Associated Equipment Dealers, Nebraska Truck Association, the National Truck Equipment Association and the Specialty Equipment Market Association and a number of states and the Arizona state legislature. However, on January 14, 2025, CARB withdrew its waiver request with the EPA and the status of the Advanced Clean Fleets rule is uncertain.

On January 20, 2025, President Trump signed Executive Order "Unleashing American Energy", which may have direct implications on the policies and regulations that impact the automotive and transportation industries. The Executive Order seeks to rescind waivers granted by the EPA for California's zero emission vehicle regulations with a focus on eliminating any "electric vehicle mandates" and terminating "state emission waivers that function to limit sales of gasoline-powered vehicles" (which would include the Advanced Clean Trucks regulation), and modify and/or eliminate the GHG standards for trucks discussed above. As a result, the status of the emission regulations discussed above remain uncertain.

Foreign, federal, state, provincial and local lawmakers also are considering a variety of other climate change proposals. These and any other future requirements could result in higher prices for vehicles, diesel engines, materials and fuel, as well as higher maintenance costs and uncertainty as to reliability of the new engines. Any of these factors could increase operating costs in the transportation industry, which would directly affect PTS’ and PTG’s customers, could reduce demand for vehicles, lead to decreased lease and rental business as customers reevaluate their needs, and affect resale values of these vehicles when PTS or PTG attempts to sell them in the future.

Self-Insurance

Our business is subject to substantial risk of loss due to significant concentrations of property value, including inventory at our locations, as well as other liabilities arising out of our operations. We retain risk relating to certain of our general liability insurance, workers' compensation insurance, vehicle physical damage insurance, property insurance, information security risk insurance, directors' and officers' insurance, and employee medical benefits in the U.S. As a result, we are likely to be responsible for a significant portion of the claims and losses incurred under these programs. The amount of risk we retain varies by program, and for certain exposures, we either have no insurance or we have pre-determined maximum loss limits for certain individual claims and/or insurance periods. Losses, if any, above the pre-determined loss limits are paid by third-party insurance carriers. Certain insurers have limited available property coverage in response to the natural catastrophes experienced in recent years.

Item 1A. Risk Factors

Our business, financial condition, results of operations, cash flows, prospects, and the prevailing market price and performance of our common stock may be affected by a number of factors, including the matters discussed below. Certain statements and information set forth herein as well as other written or oral statements made from time to time by us or by our authorized officers on our behalf, constitute “forward-looking statements” within the meaning of the Federal Private Securities Litigation Reform Act of 1995. Words such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “goal,” “plan,” “seek,” “project,” “continue,” “will,” “would,” and variations of such words and similar expressions are intended to identify such forward-looking statements. We intend for our forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and we set forth this statement in order to comply with such safe harbor provisions. You should note that our forward-looking statements speak only as of the date of this Annual Report on Form 10-K or when made, and we undertake no duty or obligation to update or revise our forward-looking statements, whether as a result of new information, future events, or otherwise.

Although we believe that the expectations, plans, intentions, and projections reflected in our forward-looking statements are reasonable, such statements are subject to known and unknown risks, uncertainties, and other factors that may cause our actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward-looking statements.

The material risks, uncertainties, and other factors that our stockholders and prospective investors should consider include the following:

Operational Risks

Macro-economic and geo-political conditions. Our performance is impacted by geo-political conditions and by general economic conditions overall and in particular by economic conditions in the markets in which we operate. These economic conditions include levels of new and used vehicle sales, availability of consumer credit, changes in consumer demand, consumer confidence levels, fuel prices, demand for trucks to move freight with respect to PTS and PTG, the rate of inflation, personal discretionary spending levels, interest rates, and unemployment rates. When the worldwide economy faltered early in 2020, we were adversely affected, and we expect a similar relationship between general economic and industry conditions and our performance in the future. Any geo-political developments that adversely affect the economies of our markets will also likely affect us. Moreover, geo-political conditions, including international conflict, can affect the vehicle supply chain as has happened with the war in Ukraine. Certain vehicle manufacturers and suppliers have experienced, and may continue to experience, difficulty sourcing certain parts which is further exacerbating the supply chain difficulties resulting from the demand for labor and the shortage of microchips and other components.

Many of our market countries have recently experienced a high rate of inflation. Inflation affects the price of vehicles, the price of parts, the rate of pay of our employees, the cost and availability of consumer credit, consumer demand, and our borrowing expenses. High rates of inflation may adversely affect consumer demand and increase our costs, which may materially and adversely affect us. Similarly, periods of rapid deflation in vehicle prices may materially and adversely affect our ability to profitably sell the affected vehicles.

Adverse conditions affecting one or more significant automotive manufacturers or suppliers will affect us. Our success depends on the overall success of the automotive and commercial vehicle industries generally and in particular, on the success of the brands of vehicles that each of our dealerships sell. In 2024, revenue generated at our BMW/MINI, Audi/Volkswagen/Porsche/Bentley, Toyota/Lexus, and Mercedes-Benz/Sprinter/smart dealerships represented 26%, 22%, 14%, and 9%, respectively, or 71% in aggregate, of our total automotive dealership revenues. In addition, our retail commercial truck operations rely principally on Freightliner and Western Star trucks (both Daimler brands). These manufacturers operate independently of us and we have no control over their operational decisions and future plans. We are subject to a concentration of risk in the event of adverse events or financial distress, including bankruptcy, impacting one or more of these manufacturers.

Significant adverse geo-political events, weather-related events, supply chain issues, or other events that interrupt vehicle or parts supply to our dealerships would likely have a significant and adverse impact on the automotive or commercial vehicle industries, including us, particularly if the events impact any of the manufacturers whose franchises

18

Table of Contents

generate a significant percentage of our revenue. In the first quarter of 2024, vehicle shipments of certain brands were delayed as a sub-component was determined to be violative of certain legal requirements relating to its place of origin. In March 2024, a cargo ship crashed into the Francis Scott Key Bridge in the Port of Baltimore resulting in closure of that port, which was the largest U.S. port by volume for deliveries of automotive vehicles and components. In April 2024, a Freightliner truck supplier experienced a fire at its facility. These events affected the timing of new vehicles deliveries to our dealerships and similar events may similarly affect the timing of deliveries or aggregate availability of inventories, which may materially and adversely affect us.

Other national and international events, conditions, and conflicts may impact the supply of vehicles or parts to the markets in which we operate, and our business could be materially adversely affected. The supply chain required to manufacture and supply parts for the vehicles we sell is highly complex and integrated. Any failure of that supply chain could materially and adversely affect us. Production disruptions and supply shortages could result in suppressed new and used vehicle sales volumes which would impact the availability and affordability of new and used vehicles and may adversely affect us.

Vehicle manufacturers exercise significant control over us and our success is largely dependent on the success of our manufacturer partners. Each of our new vehicle dealerships and distributor operations operate under franchise and other agreements with automotive manufacturers, commercial vehicle manufacturers, or related distributors. These agreements, and in certain cases, related framework agreements, govern almost every aspect of the operation of our dealerships and give manufacturers the discretion to terminate or not renew our franchise agreements for a variety of reasons, including certain events outside our control such as accumulation of our stock by third parties. In certain cases, they also limit our ability to acquire dealerships on a national, regional, and local basis, and from time to time, we are precluded from acquiring additional franchises of certain manufacturers, or subject to other adverse actions, to the extent we are not meeting specified performance criteria at our existing stores (with respect to matters such as sales volume, sales effectiveness, and customer satisfaction or loyalty) until our performance improves in accordance with the agreements, subject to applicable state franchise laws.

Without franchise or distributor agreements, we would be unable to sell or distribute new vehicles or perform manufacturer authorized warranty service. If a significant number of our franchise agreements are terminated, not renewed, or, with respect to our distributor operations, a competing distributor were introduced, we would be materially affected. Manufacturers also have the right to establish new franchises or relocate existing franchises, subject, in the U.S., to applicable state franchise laws. While we expect that we will be able to renew our franchise agreements in the ordinary course, we cannot guarantee that all of our franchise agreements will be renewed, that the terms of the renewals will be favorable to us or that the manufacturers will not take other adverse actions under our arrangements with them. It is also possible that our stores will not be able to comply with manufacturers’ sales, customer satisfaction, loyalty, performance, facility, and other requirements in the future, which may affect our ability to acquire new stores or renew our franchise agreements, or subject us to other adverse actions, including the termination or compelled sale of a franchise, any of which could have a material adverse effect on our financial condition and results of operations.

In addition to the control afforded to manufacturers as a result of our franchise and other agreements, we also rely on our manufacturer partners for many aspects of our business and the success of our dealerships is dependent, in large part, on their success. For instance, we rely on our manufacturer partners exclusively for new vehicle inventory, and our ability to successful sell new vehicles is dependent on the manufacturers' ability to design, manufacture and allocate to our dealerships a desirable mix of high-quality, competitively priced, technologically current and legally compliant vehicle inventories in quantities sufficient to meet our and our customers' demand. We also receive direct financial support and assistance from certain manufacturers and their affiliates, including captive finance companies, across various aspects of our business, including floorplan assistance and advertising assistance, and rely on manufacturers to pay us for warranty and service contract work for vehicles under manufacturer product warranties and service contracts where we directly bill the manufacturer instead of invoicing the customer directly. Our business, results of operations, and financial condition could be materially adversely affected as a result of any event that has an adverse effect on the vehicle manufacturers on which we rely for inventory, support and payment, or in the event such manufacturers fail to maintain the goodwill associated with their respective brands, which adverse consequences may be wholly outside of our control. See the risks captioned "Adverse conditions affecting one or more significant automotive manufacturers or suppliers will affect us" above and "Brand reputation" below.

The success of our commercial vehicle distribution and other business is directly impacted by availability and demand for the vehicles and other products we distribute. We are the exclusive distributor of Western Star commercial trucks, MAN commercial trucks and buses, and Dennis Eagle refuse collection vehicles, together with associated parts, across Australia, New Zealand, and portions of the Pacific. We are also the distributor of diesel and gas engines and power

19

Table of Contents

systems in these same markets. The profitability of these businesses depends upon the number of vehicles, engines, power systems, and parts we distribute, which in turn is impacted by demand for these products. We believe demand is subject to general economic conditions, exchange rate fluctuations, regulatory changes, competitiveness of the products, and other factors over which we have limited control. In the event sales of these products are fewer than we expect, our related results of operations and cash flows for this aspect of our business may be materially adversely affected. The products we distribute are principally manufactured at a limited number of locations. In the event of a supply disruption, sufficient quantities of vehicles, engines, power systems, and parts are not made available to us, or if we accept these products and are unable to economically distribute them, our cash flows or results of operations may be materially adversely affected.

Australian economic conditions. Our commercial vehicle distribution and other operations in Australia and New Zealand may be impacted by local and regional economic conditions and in particular, the price of commodities such as copper and iron ore, which may impact the desire of our customers to operate their mining operations and replace their vehicle fleets. Adverse pricing concerns of those, and other commodities, may have a material adverse effect on our ability to distribute, and/or retail, commercial vehicles and other products profitably. These same conditions may also negatively impact the value of the Australian and New Zealand Dollar versus the U.S. Dollar, which negatively impacts our U.S. Dollar reported financial results and the pricing of products sold by Penske Australia, which are manufactured in the U.S., U.K., and Germany.

Additional risks relating to PTS. PTS' business has additional risks to those in the retail business, including:

Customers. PTS has a more concentrated customer base than we do and is subject to changes in the financial health of its customers, changes in their asset utilization rates, and increased competition for those customers.

Workforce. PTSrequires a significant number of qualified drivers and technicians, which may be difficult to hire, and is subject to increased compliance costs or work stoppages relating to those employees, particularly in regard to changes in labor laws and time of work rules regarding those employees. PTS contributes to several U.S. multi-employer pension plans that provide defined benefits to approximately 2,430 associates covered by collective bargaining agreements. If they withdraw or are deemed to withdraw from participation in any of these plans, then applicable law could require them to make withdrawal liability payments to the plan. If any of those plans were deemed to be underfunded, PTS could be subject to additional assessments, which could be substantial.

Fleet risk. As one of the largest purchasers of commercial trucks in North America, PTS requires continued availability from truck manufacturers and suppliers of vehicles and parts for its fleet, which may be uncertain, in particular if a significant recall were to occur. PTS is affected by the same supply issues noted above and any failure of the supply chain resulting in limited availability of new trucks or parts may have a material adverse impact on PTS. In addition, because PTS sells a large number of trucks each year and is subject to residual risk for the vehicles it leases to customers, changes in values of used trucks affect PTS' profitability.

PTS also bears the residual risk on the value of its vehicles when a customer's lease for those vehicles expires or when its holding period for rental vehicles ends. If demand for used vehicles declines, PTS may obtain lower sales proceeds upon their sale. A reduction in proceeds from sales of used vehicles in PTS’ fleet could cause them to sustain a substantial loss or require them to depreciate those vehicles at a more accelerated rate. Any reduction in the resale values of the vehicles in its fleet could adversely affect its profitability.

Capital markets risk. PTS relies on banks and capital markets to fund its operations and capital commitments. PTS has a significant amount of total indebtedness, which it uses in part to purchase its vehicle fleet and therefore, is subject to changes in, and continued access to, capital markets.

Regulatory Requirements and Vehicle Mandates. Increasing efforts to control greenhouse gas emissions are likely to have an effect on PTS' (and PTG's) business and results of operations as further discussed below under "Vehicles Emissions Regulation". Any of the factors noted could increase operating costs in the transportation industry, which would directly affect PTS' and PTG's customers and could reduce demand for vehicles. The new technology and legal requirements may also affect resale values of these vehicles when PTS or PTG attempts to sell them in the future.

Centralized Information Systems. PTS relies heavily on centralized information systems to process lease and rental transactions, manage its fleet of vehicles, account for its activities, and otherwise conduct its business. A failure of a major system, or a major disruption of communications between the system and the locations it serves, could cause a loss of reservations, interfere with PTS' ability to manage its fleet, impede real-time diagnostics of vehicles, slow leasing, rental, and sales processes, and otherwise adversely affect PTS' ability to manage its business.

Strategic Risks

Brand reputation. Our businesses and our commercial vehicle operations, in particular, as those are more concentrated with a particular manufacturer, are impacted by consumer demand and brand preference, including consumers' perception of the quality of those brands. A decline in the quality and brand reputation of the vehicles or other products we sell or distribute, as a result of events such as manufacturer recalls or legal proceedings, may adversely affect our business. If such events were to occur, the profitability of our business related to those manufacturers could be adversely affected.

Our business is very competitive. We generally compete with other franchised dealerships in our markets, used vehicle dealerships, private market buyers and sellers of used vehicles, an increasing number of internet-based vehicle sellers, electric vehicle manufacturers that sell directly to consumers, national and local service and repair shops and parts retailers with respect to commercial vehicles, distributors of similar products, and manufacturers in certain markets. Purchase decisions by consumers when shopping for a vehicle are extremely price sensitive. The level of competition in the market can lead to lower selling prices and related profits. If there is a prolonged drop in retail prices or if new vehicle sales are allowed to be made over the internet or otherwise without the involvement of franchised dealers, our business could be materially adversely affected.

Changes to the retail delivery model, including increased digital retailer competition, efforts to sell vehicles directly outside the franchise system, and transition to an agency model of distribution could adversely affect our business, results of operations, financial condition, and cash flows.

Competition from online retailers. The automotive retail industry is experiencing competition in the used vehicle market from companies with a primarily online business model, including companies such as Carvana and others. We may face increased competition for market share with these non-traditional delivery models and digital retailers over time, which could materially and adversely affect our results of operations. We cannot be sure that our initiatives will be successful or that the amount we invest in these initiatives will result in our maintaining or enhancing our market share and continued or improved financial performance.

Sales outside the franchise system. In recent years, new electric vehicle manufacturers have been able to conduct new vehicle sales outside of the franchised automotive system as new entrants. While the sales levels of these new entrants were approximately 4.2% of new vehicles in the U.S. and approximately 2.6% of new vehicles in the U.K. for the year ended December 31, 2024, continued market share gains by manufacturers operating outside the franchise system may materially and adversely affect us. Moreover, while we expect continued good relations with our manufacturer partners, should U.S. franchise laws be repealed or amended to allow our existing manufacturer partners to effectively operate outside the franchised system, our results of operations may be materially and adversely impacted. Our franchised automotive dealers in the U.K., European Union, Australia, and Japan operate effectively without U.S. franchise law protections.

Agency. Some of our key automotive manufacturer partners have either implemented or announced plans to explore the agency model of selling new vehicles in the U.K. and other countries. We receive a fee for facilitating the sale by the manufacturer of a new vehicle but do not hold the vehicle in inventory. Vehicles sold under this agency model are counted as new agency units sold instead of new retail units sold by us, and only the fee we receive from the manufacturer, not the price of the vehicle, is reported as new revenue with no corresponding cost of sale. The long-term impact of the agency model at these dealerships as well as other agency models proposed by our manufacturer partners remains uncertain. We believe transition to an agency model in the U.S. would be difficult for the manufacturers in light of U.S. franchise laws. See Item 1. Business, "Regulations" and Item 1A. Risk Factors, "Sales outside the franchise system" and "Other Regulatory Issues."

New mobility models and vehicle electrification will continue to result in rapid changes to the automotive and trucking industries.Shared vehicle services such as Uber and Lyft provide consumers with increased choice in their personal mobility options. The effect of these and similar mobility options on the retail automotive industry is uncertain and may include lower levels of new vehicles sales but with increasing miles driven, which could require additional demand for vehicle maintenance. Most major vehicle manufacturers have announced plans to electrify some or all of their new vehicle fleets in response to concerns about the environment and due to regulatory requirements to limit vehicle emissions. We expect to continue to sell electric and hybrid gas/EVs through our franchised dealerships; however, our service revenues may decline over time as these vehicles may require less physical maintenance than gas and hybrid vehicles due to the absence of certain parts systems. Conversely, increasing consumer adoption of EVs may present new service opportunities, including with respect to range maintenance and optimization, cooling protection, torque protection, tire replacement, battery replacement, and warranty on newly released models.

The effects of the eventual adoption of driverless vehicles are uncertain. Technological advances are facilitating the evolution of driverless vehicles. While many manufacturers offer varying degrees of driver assistance technology, the timing of adoption of true driverless vehicles remains uncertain due to regulatory requirements, additional technological requirements, and uncertain consumer acceptance of these vehicles. The effect of driverless vehicles on the automotive retail and trucking industries is uncertain and could include changes in the level of new and used vehicles sales, the price of new and used vehicles, the levels of service required by driverless vehicles and the role of franchised dealers, any of which could materially and adversely affect our business.

Key personnel. We believe that our success depends to a significant extent upon the efforts and abilities of our senior management and in particular, upon Roger Penske who is our Chair and Chief Executive Officer. To the extent Mr. Penske, or other key personnel, were to depart from our Company unexpectedly, our business could be significantly disrupted.

Financial Risks

Leverage. Our significant debt and other commitments expose us to a number of risks, including:

Cash requirements for debt and lease obligations.A significant portion of the cash flow we generate must be used to service the interest and principal payments relating to our various financial commitments, including $4.0 billion of floor plan notes payable, $1.9 billion of non-vehicle long-term debt, and $5.3 billion of future lease commitments(including extension periods that are reasonably assured of being exercised and assuming constant consumer price indices). A sustained or significant decrease in our operating cash flows could lead to an inability to meet our debt service or lease requirements or to a failure to meet specified financial and operating covenants included in certain of our agreements. If this were to occur, it may lead to a default under one or more of our commitments and potentially the acceleration of amounts due, which could have a significant and adverse effect on us.

Credit Availability. Because we finance the majority of our operating and strategic initiatives using a variety of commitments, including floor plan notes payable and revolving credit facilities, we are dependent on continued availability of these sources of funds. If these agreements are terminated or we are unable to access them because of a breach of financial or operating covenants or otherwise, we will likely be materially affected.

Interest rate variability. The interest rates we are charged on a substantial portion of our debt, including the floor plan notes payable we issue to purchase the majority of our inventory, are variable, increasing or decreasing based on changes in certain published interest rates. Increases to such interest rates have resulted in and may continue to result in higher interest expense for us, which negatively affects our operating results. Because many of our customers finance their vehicle purchases, increased interest rates may also decrease vehicle sales due to affordability, which would negatively affect our operating results.

Impairment of our goodwill or other indefinite-lived intangible assets has in the past had, and in the future could have, a material adverse impact on our earnings. We evaluate goodwill and other indefinite-lived intangible assets for impairment annually and upon the occurrence of an indicator of impairment. Our process and results for impairment testing of these assets is described further under “Impairment Testing” in Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates. If we determine that the amount of our goodwill or other indefinite-lived intangible assets are impaired at any point in time, we would be required to reduce the value of these assets on our balance sheet, which could also result in a material non-cash impairment charge that could also have a material adverse effect on our results of operations for the period in which the impairment occurs.

Performance of sublessees. In connection with the sale, relocation, and closure of certain of our businesses, we have entered into a number of third-party sublease agreements. The rent paid by our sub-tenants on such properties in 2024 totaled approximately $16.2 million. In the aggregate, we remain ultimately liable for approximately $130.8 million of such lease payments including payments relating to all available renewal periods. We rely on our sub-tenants to pay the rent and maintain the properties covered by these leases. In the event a subtenant does not perform under the terms of their lease with us, we could be required to fulfill such obligations, which could have a significant and adverse effect on us.

International and foreign currency exchange risk. We have significant operations outside of the U.S. that expose us to changes in foreign currency exchange rates and to the impact of economic and political conditions in the markets where we operate. As exchange rates fluctuate, our results of operations as reported in U.S. Dollars fluctuate. For example, if the U.S. Dollar strengthens against the British Pound, our U.K. results of operations would translate into less U.S. Dollar reported results. Sustained levels or an increase in the value of the U.S. Dollar, particularly as compared to the British Pound, could result in a significant and adverse effect on our reported results.

22

Table of Contents

Joint ventures. We have significant investments in a variety of joint ventures, including retail automotive operations in Italy and Spain. We have a 28.9% interest in PTS. We expect to receive annual operating distributions from PTS and the other ventures and in the case of PTS, realize significant cash savings on taxes. These benefits may not be realized if the joint ventures do not perform as expected, or if changes in tax, financial, or regulatory requirements negatively impact the results of the joint venture operations. Our ability to dispose of these investments may be limited. In addition, the relevant joint venture agreement and other contractual restrictions may limit our access to the cash flows of these joint ventures. For example, certain of PTS' debt agreements allow partner distributions only as long as it is not in default under those agreements and the amount it pays does not exceed 50% of its consolidated net income, unless its debt-to-equity ratio is less than 3.0 to 1.0, in which case its distributions may not exceed 80% of its consolidated net income.

Legal and Compliance Risks

Vehicle Emissions and Other Environmental Regulations. Federal and state governments and regulators in our markets have increasingly placed restrictions and limitations on new vehicles in an effort to combat perceived negative environmental effects. In response to concerns that emissions of carbon dioxide and certain other gases, referred to as "greenhouse gases" or "GHGs," may be contributing to warming of the Earth's atmosphere, climate change-related legislation and policy changes to restrict GHGs have been implemented, at state and federal levels in a manner that impacts our business. The most significant of these regulations and other requirements are described above under Item 1. Business, "Regulation" and "Vehicle Emissions Regulation".

Significant increases in fuel economy requirements, new battery warranty standards, and new restrictions on emissions on vehicles and fuels could adversely affect prices, availability, and demand for the vehicles that we sell, which could materially adversely affect us. Such vehicles may also not be able to be produced in the quantities required, or, if produced, may not be able to be sold to consumers in light of customer reluctance to transition to EVs. Adoption of EVs will increasingly require the generation of additional electricity and nationwide electric charging infrastructures which may be unavailable in our markets. While increasing consumer adoption of EVs may present new service opportunities, including with respect to range maintenance and optimization, cooling protection, torque protection, tire replacement, battery replacement, and warranty on newly released models, our service revenue per vehicle may decline over time as these EVs may require less physical maintenance than gas and hybrid vehicles due to the absence of certain parts systems.

PTG sells new and used heavy- and medium-duty commercial trucks, parts and service, and offers collision repair services. PTS, with its broad product offering including full-service truck leasing, contract maintenance, and truck rental, along with logistics services, is one of the largest purchasers of commercial trucks in North America. Should future regulations or consumer sentiment hinder our or PTS' ability to maintain, acquire, sell, service, or operate trucks, we may be adversely affected. Should additional states adopt CARB regulations, PTG and PTS could experience increased compliance costs, additional operating restrictions, or changes in demand for their products and services, which could have a material adverse effect on our business, financial condition and results of operations. New regulations could be adopted that require moving to zero emission formats and/or the implementation of more stringent emissions controls. For example, original equipment manufacturers may be required to install additional engine components, additional aerodynamic features or low-rolling resistance tires to comply with fuel economy regulations, which may result in higher costs associated with more complex components and a shorter useful tread life for tires, increasing operating costs for customers, suppliers, and our businesses. Foreign, federal, state, provincial and local lawmakers also are considering a variety of other climate change proposals, including prohibiting the use of certain substances with high "global warming potential."

On January 20, 2025, President Trump signed Executive Order "Unleashing American Energy", which may have direct implications on the policies and regulations that impact the automotive and transportation industries. The Executive Order seeks to rescind waivers granted by the EPA for California's zero emission vehicle regulations with a focus on eliminating any "electric vehicle mandates" and terminating "state emission waivers that function to limit sales of gasoline-powered vehicles" and modify and/or eliminate certain GHG standards for trucks. As a result, the status of the emission regulations discussed above and the impact of the new presidential administration on these or other U.S. federal policies in this area remains uncertain.

Other Regulatory Issues. We are subject to a wide variety of regulatory activities and oversight, including:

Governmental regulations, claims, and legal proceedings. Governmental regulations affect almost every aspect of our business, including the fair treatment of our employees, wage and hour issues, and our financing activities with customers. In California, previous judicial decisions have called into question whether long-standing methods for compensating dealership employees comply with the local wage and hour rules and may do so again. We could be susceptible to claims or related actions if we fail to operate our business in accordance with applicable laws or it is

determined that long-standing compensation methods did not comply with local laws. Many laws and regulations applicable to our business were adopted prior to the introduction of online vehicle sales, the Internet and certain digital technology, generally. As a result, we are tasked with maintaining compliance in an uncertain regulatory environment. Claims arising out of actual or alleged violations of law which may be asserted against us or any of our dealers by individuals, through class actions, or by governmental entities in civil or criminal investigations and proceedings, may expose us to substantial monetary damages which may adversely affect us.

Our financing activities with customers are subject to truth-in-lending, consumer leasing, equal credit opportunity, and similar regulations as well as motor vehicle finance laws, installment finance laws, insurance laws, usury laws, and other installment sales laws. In the U.K., the Financial Conduct Authority (the "FCA") regulates financial services firms and financial markets, including our activities in acting as broker for the financing of vehicle sales. The FCA is investigating the historic use of discretionary commission arrangements ("DCAs") amid concerns that this practice may have been unfair to customers. The purpose of the investigation is to consider whether the historic use of DCAs caused customers to pay too much for their car loans and, if so, to consider potential remediation measures. The investigation is being undertaken after the Financial Ombudsman Service (a public body, which resolves financial complaints) determined that DCAs, in two separate cases which do not involve us, had caused financial losses to customers. We await the outcome of the FCA’s investigation which is expected in May of 2025. Any regulatory or judicial outcome that ultimately results in the refund of historical commissions paid to us or that reduces the commissions paid to us could materially and adversely affect us.

On October 25, 2024, the U.K. Court of Appeal (the second highest court in the U.K.) issued a judgment in the case Johnson v Firstrand Bank Ltd, Wrench v Firstrand Bank Ltd and Hopcraft v Close Brothers Ltd, which required those lenders to repay those customers the commissions paid to the dealers for their vehicle finance agreements, determining that, in those cases, there was a duty to the customers to disclose the amount of the commissions paid to those dealers. We believe this judgment is contrary to existing guidance issued by the FCA, and the U.K. Supreme Court (the highest court in the U.K.) has granted the lenders permission to appeal the Judgment, with an expedited judgment by the Supreme Court expected in the first half of 2025. Our U.K. consumer lending partners now require us to disclose to customers the commissions we receive from financing the purchase of their vehicle.

While the focus of the FCA’s potential redress to customers, and the Judgment above, has been on the lenders and not dealers, we may experience changes to our processes and/or claims for repayment of historical commissions we have received from customers, which amounts could materially and adversely affect us.

Privacy Regulation. We are subject to numerous laws and regulations in the U.S. and internationally designed to protect the information of clients, customers, employees, and other third parties that we collect and maintain, including the European Union General Data Protection Regulation (the "EUGDPR") and the United Kingdom General Data Protection Regulation (the "UKGDPR"). Both the EUGDPR and UKGDPR, among other things, mandate requirements regarding the handling of personal data of employees and customers, including its use, protection, and the ability of persons whose data is stored to correct or delete such data about themselves. The state of California has similar laws which includes a private right of action for certain violations of law. Multiple other U.S. states have also enacted comprehensive consumer privacy laws, and additional states may follow. These laws pose increasingly complex and rigorous compliance challenges, which may increase our compliance costs and related risk. If we fail to comply with these laws or other similar regulations applicable to our business, we could be subject to reputational harm and significant litigation, monetary damages, regulatory enforcement actions, or fines in one or more jurisdictions. For example, a failure to comply with the UKGDPR could result in fines up to the greater of £17.5 million or 4% of annual global revenues.

Recalls. Legislative and regulatory bodies from time to time have considered laws or regulations that would prohibit companies from renting or selling any vehicle that is subject to a recall until the recall service is performed. Whether any such prohibition may be enacted, and its ultimate scope, cannot be determined at this time. If a law or regulation is enacted that prevents the sale of vehicles until recall service has been performed, we could be required to reserve a significant portion of our vehicles from being available for sale for even a minor recall unrelated to vehicle safety. In addition, various manufacturers have issued stop sale notices in relation to certain recalls that require that we retain vehicles until the recall can be performed, whether or not parts are then available. While servicing recall vehicles yields parts and service revenue to us, the inability to sell a significant portion of our vehicles could increase our costs and have an adverse effect on our results of operations if a large number of our vehicles are the subject of simultaneous recalls or if needed replacement parts are not in adequate supply.

Tariff and trade risk. Changes or increases in tariffs, trade restrictions, the negotiation of new trade agreements, non-tariff trade barriers, local content requirements, uncertainty surrounding global trade policies, and the imposition of new or retaliatory tariffs against certain countries or covering certain products, including vehicles and parts may affect our competitive position and impair our ability to sell foreign vehicles and parts profitably. On February 1, 2025, President Trump issued executive orders imposing a 25% tariff on certain product imports from Mexico and Canada, and a 10% tariff on product imports from China, although certain of these tariffs have been temporarily stayed. Further, on February 10, 2025, President Trump implemented a 25% tariff on imported steel and aluminum, proposed to be effective beginning on March 12, 2025, and has suggested the implementation of a 25% tariff on imported automobiles. If maintained, these and other newly announced tariffs and the potential escalation of trade disputes are expected to broadly affect the automotive industry, including manufacturers of vehicles, parts and supplies. The extent of the tariffs and the resulting impact on general economic conditions and on our business are uncertain and depend on various factors, such as negotiations between the U.S. and affected countries, the duration of such tariffs, the responses of other countries or regions to such tariffs, the actual increases in the costs of imported vehicles, products and raw materials, and exemptions or exclusions that may be granted. Should tariffs increase and be sustained, our inventory acquisition and carrying costs, and the production costs for many of our manufacturer and supplier partners, may be increased, which costs may be passed on to us and consumers through higher prices for many new vehicles and certain parts we sell. These increased prices may adversely affect our new vehicle sales and related finance and insurance sales and may adversely impact demand for such vehicles and parts, potentially impacting our ability to sell them profitably. Moreover, new rules in place after the Brexit accord between the European Union and the U.K. require varying levels of content in vehicles to originate in either the U.K. or the European Union to remain tariff free. If automotive manufacturers cannot meet these content rules, there may be import tariffs on any affected vehicles, which could adversely affect our U.K. results.

Franchise laws in the U.S. In the U.S., state law generally provides protections to franchised vehicle dealers from discriminatory practices by manufacturers and from unreasonable termination or non-renewal of their franchise agreements. In many states, the laws require that new vehicle sales be conducted exclusively by automotive retailers (not manufacturers). Should U.S. franchise laws be repealed or amended to allow our existing manufacturer partners to effectively operate outside the franchised system, our results of operations may be materially and adversely impacted. See the risk factor captioned “Sales outside the franchise system” above.

Changes in law. New laws and regulations at the state and federal level may be enacted which could materially adversely impact our business. For example, in December 2023, the U.S. Federal Trade Commission announced its new Combating Auto Retail Scams Rule, which would change the way vehicles are advertised and sold in the U.S. The rule originally was to take effect in July 2024. However, as a result of legal challenges, the rule was vacated in January 2025. Similar rules or state laws, all of which could be imposed on our business, could complicate the transaction process and increase compliance costs and risk, among other effects, which could have a significant and adverse effect on us.

Climate change and environmental regulations. Scientific evidence suggests that the globe is warming potentially resulting in an environment more prone to natural disasters, such as flooding or wild fires. To date, we have seen increases in our cost to insure against such risks, which costs could continue to increase should this trend continue.We are subject to a wide range of environmental laws and regulations, including those governing discharges into the air and water; the operation and removal of storage tanks; and the use, storage, and disposal of hazardous substances. In the normal course of our operations we use, generate, and dispose of materials covered by these laws and regulations. In the face of climate change, these laws could become more stringent. We face potentially significant costs relating to claims, penalties, and remediation efforts in the event of non-compliance with existing and future laws and regulations. Furthermore, should climate change continue, we expect further regulation of internal combustion engines and vehicle emissions which may affect the types of vehicles we sell and service. We cannot predict the future costs to our businesses for these developments.

Accounting and disclosure rules and regulations. Significant changes to generally accepted accounting principles in the U.S. ("GAAP") could significantly affect our reported financial position, earnings, and cash flows upon adoption and effectiveness. For example, a change to lease accounting could affect PTS customers' decisions to purchase or lease trucks, which could adversely affect their business if leasing becomes a less favorable option. See the disclosure provided under "Recent Accounting Pronouncements" in Part II, Item 8, Note 1 of the Notes to our Consolidated Financial Statements for additional detail on accounting standard updates that could have an impact on us. In addition, we are subject to various reporting regimes in the U.S. and internationally. In the U.K., we are subject to the Climate-related Financial Disclosure Regulations which require disclosure of climate risks and opportunities, among other matters. In Australia, we are subject to the mandatory climate-related financial disclosures under the Treasury Laws

25

Table of Contents

Amendment (Financial Market Infrastructure and Other Measures) Act 2024. We are also subject to California’s Climate Corporate Data Accountability Act and Climate-Related Financial Risk Act which require disclosure of emissions and other matters. Further, we are subject to the European Sustainability Reporting Standards which also require emissions and other disclosures, as well as any regulations regarding climate and sustainability disclosures eventually adopted by the U.S. Securities and Exchange Commission. We are also subject to regulations and corporate financial reporting and auditing obligations in other jurisdictions that we operate in. These multiple sets of disclosures standards are not yet clearly defined and require duplicative and sometimes conflicting disclosures across our individual and consolidated business units, and the failure to comply with these standards may result in fines, penalties and reputational harm. Compliance with these standards will subject us to additional expenses and compliance risk which may adversely affect our business.

Related parties. Our two largest stockholders, Penske Corporation and its affiliates (“Penske Corporation”) and Mitsui & Co., Ltd. and its affiliates (“Mitsui”), together beneficially own approximately 71% of our outstanding common stock. The presence of such significant stockholders results in several risks, including:

Our principal stockholders have substantial influence. Penske Corporation and Mitsui have entered into a stockholders agreement pursuant to which they have agreed to vote together as to the election of our directors. As a result, Penske Corporation has the ability to control the composition of our Board of Directors, which may allow it to control our affairs and business. This concentration of ownership coupled with certain provisions contained in our agreements with manufacturers, our certificate of incorporation, and our bylaws could discourage, delay, or prevent a change in control of us.

Some of our directors and officers may have conflicts of interest with respect to certain related party transactions and other business interests. Roger Penske, our Chair and Chief Executive Officer and a director, holds the same offices at Penske Corporation. Robert Kurnick, Jr., our President and a director, is also the Vice Chair and a director of Penske Corporation and an Advisory Board member of PTS. Bud Denker, our Executive Vice President, Human Resources, is also the President of Penske Corporation. Each of these officers is paid much of their compensation by Penske Corporation. The compensation they receive from us is based on their efforts on our behalf; however, they are not required to spend any specific amount of time on our matters. The Vice Chair of our Board of Directors, Greg Penske, is the son of our Chair and also serves as a director of Penske Corporation. Michael Eisenson, one of our directors, is also a director of Penske Corporation and an Advisory Board member of PTS. Lisa Davis, one of our directors, is also an Advisory Board member of PTS. Kota Odagiri, one of our directors, is also an employee of Mitsui. Roger Penske also serves as Chairman of Penske Transportation Solutions, for which he is compensated by PTS.

Penske Corporation ownership levels. Certain of our agreements have clauses that are triggered in the event of a material change in the level of ownership of our common stock by Penske Corporation, such as our trademark agreement between us and Penske Corporation that governs our use of the “Penske” name which can be terminated 24 months after the date that Penske Corporation no longer owns at least 20% of our voting stock. We may not be able to renegotiate such agreements on terms that are acceptable to us, if at all, in the event of a significant change in Penske Corporation's ownership.

We have a significant number of shares of common stock eligible for future sale.Penske Corporation and Mitsui own approximately 71% of our common stock, and each has two demand registration rights that could result in a substantial number of shares being introduced for sale in the market. We also have a significant amount of authorized but unissued shares. Penske Corporation has pledged a substantial portion of its shares of our common stock as collateral to secure a loan facility. A default by Penske Corporation could result in the foreclosure on those shares by the lenders, after which the lenders could attempt to sell those shares on the open market or to a third party. The introduction of any of these shares into the market could have a material adverse effect on our stock price.

General Risks

We rely on third parties for the majority of our information systems and the availability and efficient operation of such systems is critical to the operation of our business.

Our information systems are fully integrated into our operations, and we rely on them to operate effectively, including with respect to electronic interfaces with manufacturers and other vendors, customer relationship management, sales and service efforts, data storage, and financial and operational reporting. The majority of our systems are provided by or licensed from third-party vendors and suppliers; the most significant of which are the dealer management systems (“DMS”) and customer relationship management ("CRM") systems used across our retail operations, which are provided by a limited number of suppliers. We also rely on third-party vendors to supply other key products and services to us and our

26

Table of Contents

customers. One or more of these third-party vendors or suppliers may experience financial distress, technology challenges, cybersecurity incidents, ransomware demands, programming errors, staffing shortages or liquidity challenges, file for bankruptcy protection, go out of business, or suffer other disruptions in their business, each of which could affect the vendors’ ability to provide services to us and our customers. If any of our vendors or suppliers fail to deliver their products or services for any reason, our business and results of operations and financial condition could be adversely impacted, and such failures may lead to broader disruptions or failures across our information systems which may expose us to customer, employee, manufacturing partner, governmental, or third-party claims or other legal liabilities.

The failure of our information systems, the failure to protect the integrity of these systems, or the interruption of these systems as discussed herein or otherwise due to natural disasters, power loss, unexpected termination of our agreements, cyber-attacks, ransomware encryptions, or other reasons such as those which resulted from the CDK Cybersecurity Incident (described below), could significantly and adversely disrupt our business operations, impact our sales, service, inventory, customer relationship management, and accounting functions and otherwise adversely affect our results of operations. For example, on June 19, 2024, we became aware that CDK Global, LLC (“CDK”), a third-party provider of information systems, including DMS software to support retail automotive and commercial truck dealership operations, was experiencing a cybersecurity incident and its systems were rendered inoperable (the “CDK Cybersecurity Incident”). Although we do not utilize CDK's DMS in our U.S. or international automotive dealership operations, our Premier Truck Group business does utilize CDK’s dealer management system and was impacted by the CDK Cybersecurity Incident. In response to the CDK Cybersecurity Incident, we immediately took precautionary containment steps to protect our systems and commenced an investigation of the incident. PTG implemented its business continuity response plans and continued to operate without the DMS at all locations through manual or alternate processes developed to respond to such incidents. On July 2, 2024, PTG was able to reconnect all of its locations to CDK’s DMS servers and restore core functionality of the software platform.

Even where business continuity responses and contingency plans, such as those noted above, are implemented to minimize disruptions caused by information systems failures, such mitigation efforts may result in decreased operational efficiencies and limit dealership productivity. Further, despite our efforts to assess, identify, and manage material risks from cybersecurity threats to our business and operations, including through evaluating key partners and third parties with whom we share our information as well as certain customer and employee information, we may not be able to protect our various systems from disruptions.

Cybersecurity. In the ordinary course of our business, we receive confidential information about our customers, employees, associates, and vendors. We collect, process, retain, and in some cases share this information in the normal course of our business, and such information is collected and stored primarily in our core information systems, including our DMS and CRM platforms. Our internal and third-party systems, including our DMS and CRM systems, are under a heightened level of risk from state actors, cyber criminals or other individuals with malicious intent to gain unauthorized access to our systems and exploit the information, including the confidential information of our customers and employees, that we gather. Cyber-attacks, such as the CDK Cybersecurity Incident described above, and threats to information systems and network and data security are becoming increasingly diverse and sophisticated, with attacks increasing in frequency, scope, and potential harm. In addition, some of our software applications are utilized by third parties who, in turn, subcontract or otherwise outsource various processes and administrative functions to additional third parties. Such third parties may have access to confidential information that is critical to our business operations and services. While our information security program includes enhanced controls to monitor third party providers' security programs, these third parties are subject to their own risks of data breaches, cyber-attacks, and other events or actions that could damage, disrupt, or close down their networks or systems, which in turn may adversely impact our business operations. For an overview of certain of our efforts related to cybersecurity risk management, strategy, and governance and our written Information Security Program, see Item 1C. Cybersecurity.

Despite the security measures we have in place or may implement in the future, we may be unable to fully detect, mitigate, or protect against cyber-attacks, ransomware attacks, computer viruses, security breaches, social engineering, malicious software, lost or misplaced data, programming errors, human errors, burglary, acts of vandalism, misdirected wire transfers or other events impacting us or our third-party service providers. Any security breach or event, whether by us directly or our third-party service providers, may result in an authorized party obtaining trade secrets, personally identifiable information or confidential information and may result in loss of revenue, increase the costs of doing business, harm our competitiveness, reputation or customer, vendor or manufacturer relationships, and have other negative operational impacts. In addition, such security breaches or events resulting in the loss or exposure of this information could result in liabilities and other significant financial exposures, including those derived from investigations, regulatory fines, penalties for violations of applicable laws and regulations, costs related to the remediation of ransomware events, litigation including consumer class actions, the imposition of penalties, or other means, any of which could have a material

adverse effect on our business, results of operations or financial condition. In addition, our failure to respond quickly and appropriately to such a security breach, or our failure to adequately test and verify the remediation of security incidents involving third parties prior to reintegration into our information systems, could exacerbate the consequences of the breach.

Property loss, business interruption, or other liabilities. Our business is subject to substantial risk of loss due to the significant concentration of property values, including vehicle and parts inventories at our operating locations; claims by employees, customers, and third parties for personal injury or property damage; and fines and penalties in connection with alleged violations of regulatory requirements. While we have insurance for many of these risks, we retain risk relating to certain of these perils, including through self-insurance, and certain perils are not covered by our insurance. Certain insurers have limited available property coverage in response to the natural catastrophes experienced in recent years. If we experience significant losses that are not covered by our insurance, whether due to adverse weather conditions or otherwise, or we are required to retain a significant portion of a loss, it could have a significant and adverse effect on us.

Item 1C. Cybersecurity

Risk Management Processes. We recognize the importance of assessing, identifying, and managing material risks from cybersecurity threats to our business and operations and developing, implementing, and maintaining robust cybersecurity measures to safeguard our information systems. As a result, we have integrated the management of cybersecurity threats into our broader risk management efforts, implementing policies and procedures to promote cybersecurity risk management and enhance mitigation efforts against cyber-attacks and similar threats. To help secure our systems that store or transmit electronic information, we have implemented multi-layered preventive controls which use aggregated intelligence to proactively detect, block and evaluate attacks. We also maintain a Chief Information Officer who is charged with implementing and overseeing our comprehensive written Information Security Program. In connection with our Information Security Program, we perform cybersecurity risk assessments at least annually to analyze the materiality of identified risks, the likelihood of such risks materializing, and the scope and intensity of adverse impacts if such risks result in the compromise of our information systems or sensitive information stored by us or on our behalf.

Our Information Security Program includes proactive measures to manage cybersecurity risks and threats, including mandatory annual security awareness training for all personnel with enhanced training for designated information security personnel; enterprise-wide phishing simulations and security assessments; a business continuity and recovery plan in the event of a cybersecurity incident; and the implementation of targeted access controls and various other measures, including multi-factor authentication, with respect to certain systems containing sensitive information. We have also implemented an incident response plan to guide our response to cybersecurity incidents, with a dedicated, cross-functional response team, including senior management from our information technology, information security, operations, finance, risk management, investor relations and legal teams, responsible for overseeing efforts related to detection, containment, threat mitigation and notification, as appropriate. We identify vulnerabilities in our information systems through proactive scanning of system assets for known vulnerabilities. Our outsourced managed security source operates 24/7, identifying threats and vulnerabilities, and our information security team regularly monitors alerts and meets to discuss trends in cybersecurity threats. We proactively manage vulnerabilities from major software publishers through a global patching program. To prevent unauthorized access to our information systems, we have a system of controls in place to manage user access to our information systems. Our employees acknowledge an acceptable use policy and are trained in how to identify information security risks in the workplace.

Third Party Engagement and Oversight. We engage third-party service providers, including consultants and auditors, to monitor and protect critical assets from cyber-attacks and to enhance certain components of our Information Security Program, including to assist us with annual security assessments, penetration and vulnerability testing, email and web filtering, endpoint protection, and consultation on certain cybersecurity enhancements.These partnerships enable us to leverage specialized knowledge and insights, ensuring our cybersecurity strategies and processes remain current. To oversee and identify cybersecurity threats associated with our use of third-party service providers, we periodically audit and review certain information security practices of critical vendors in possession of sensitive information, including through seeking responses to cybersecurity questionnaires. In the ordinary course of business, we also rely on contractual obligations from certain third-party service providers to meet certain information security standards and to notify and cooperate with us in the event of qualifying cybersecurity incidents.
