Table of Contents PART I Item 1. Business. Overview Carlisle Companies Incorporated (“Carlisle,” the “Company,” “we,” “us” or “our”) is a leading supplier of innovative building envelope products and solutions for more energy-efficient buildings. Through our building products businesses, Carlisle Construction Materials and Carlisle Weatherproofing Technologies, and family of leading brands, Carlisle delivers innovative, labor reducing and environmentally responsible products and solutions to customers through the Carlisle Experience. Our Company website is www.carlisle.com, through which we make available, free of charge, our Annual Report on Form 10- K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and all amendments to those reports, as soon as reasonably practicable after these reports are electronically filed with or furnished to the Securities and Exchange Commission (“SEC”). Information on, or that can be accessed through, our website is not incorporated by reference and should not be considered part of this Annual Report on Form 10-K. All references to "Notes" refer to our Notes to Consolidated Financial Statements in this Annual Report on Form 10-K. Business Strategy We strive to be a leading manufacturer and supplier of innovative building envelope products and solutions that make buildings more energy-efficient in the markets we serve. Vision 2030, our strategic plan, builds on Carlisle’s track record of success and our pivot to a pure play building products portfolio, leveraging mega trends around energy-efficiency, labor- savings, and the re-roofing cycle, to generate above market growth driven by innovation, the Carlisle Experience, and the Carlisle Operating System ("COS"). The key pillars of Vision 2030 are well-ingrained throughout the Company and guide our value-creating strategy. They include (1) driving above market organic revenue growth through continued investment in innovation, (2) maintaining best-in-class production, service, and delivery capabilities to provide the Carlisle Experience to our customers, (3) using COS, an operating structure and strategy deployment system based on lean enterprise and six sigma principles, to consistently drive efficiencies and operating leverage, (4) building scale with synergistic acquisitions, (5) continuing to invest in and develop exceptional talent, and (6) maintaining a balanced, returns-focused approach to capital deployment which includes returning excess capital to stockholders. COS is a continuous improvement process that defines the way we do business and is deeply embedded in our culture throughout Carlisle’s operations. Waste is eliminated and efficiencies are improved enterprise-wide, driving both improvements to our sustainability efforts by reducing our carbon footprint and increasing profitability. These efforts expand beyond production areas, as COS drives new product innovation, engineering, supply chain management, warranty and product rationalization. As demand accelerates for energy-efficient solutions for the sustainable buildings of the future, we will continue to emphasize the development of energy-efficient products, systems, and solutions for the roof and throughout the building envelope that reduce carbon emissions from the built environment which is estimated to contribute as much as 30% of annual greenhouse gas ("GHG") emissions. We intend to continue to seek synergistic acquisitions that will enhance our ability to service our customers with a broader set of energy-efficient solutions. Refer to Note 3 for further discussion of acquisitions made during the past three years. We believe our proactive approach to continuous improvement initiatives and focus on delivering the Carlisle Experience to our customers enables us to maintain resilient margins. We remain focused on continuing our value-creating journey with the proven foundational pillars of Vision 2030 ingrained in our Carlisle culture of continuous improvement and returns-focused capital deployment. 3

Table of Contents Description of Business by Segment Carlisle Construction Materials (“CCM”) Products, Markets and Locations The CCM segment has evolved from a supplier of the first single-ply ethylene propylene diene monomer (“EPDM”) roofing membranes in the early 1960s to today, where we deliver innovative, easy-to-install and energy-efficient solutions through the Carlisle Experience for customers who are creating the sustainable buildings of the future. CCM is a manufacturer and supplier of premium roofing products and related technologies primarily for the commercial construction market. CCM offers high-performance, single-ply roofing solutions that include EPDM, thermoplastic polyolefin (“TPO”), polyvinyl chloride (“PVC”), architectural metal and roof garden systems. EPDM, TPO and PVC membrane and polyisocyanurate ("polyiso") insulation are sold together in warranted systems or separately in non-warranted systems to the new construction, repair and replacement, and general construction markets. These products are primarily sold under the Carlisle SynTec, Versico, Weatherbond and Hunter Panels brands in the United States of America (“U.S.” or “United States”) and throughout the world, and EPDM membranes under the Resitrix and Hertalan brands primarily in Europe. CCM operates manufacturing facilities located throughout the United States, its primary market, and in Germany, the Netherlands, the United Kingdom ("U.K.") and Romania. The majority of CCM’s products are sold through a network of authorized sales representatives and distributors in North America and Europe. Key Raw Materials Key raw materials for this segment include methylene diphenyl diisocyanate (“MDI”), polyol, EPDM polymer, TPO polymer, carbon black and coated steel. These raw materials generally have at least two vendor sources. The vendor typically has multiple processing facilities for key raw materials that are single sourced. Seasonality Revenues and earnings for CCM have historically been higher in the second and third quarters due to increased construction activity during those periods from favorable weather conditions. Market Factors CCM serves a large and diverse customer base; however, in 2025 CCM's two largest customers represented 33% of the Company’s consolidated revenues. The loss of either of these customers could have a material adverse effect on the Company's consolidated revenues and operating income. Both of these customers' business is covered under a number of independent local agreements. Demand for CCM’s energy-efficient roofing solutions is primarily driven by the need to replace older, existing roofs on non- residential structures, and to a lesser extent, new construction. Notably, CCM’s backlog of orders is not a significant factor for the segment, and thus not a reliable indicator of intermediate-term revenue as most products have relatively short order-to- delivery periods. This segment faces competition from several competitors that produce roofing systems predominantly for commercial and building applications. The level of competition within this market varies by product line and region. As one of four major manufacturers in the single-ply industry, CCM competes through innovative products, long-term warranties and customer service. CCM offers separately priced extended warranty contracts on certain of its products ranging from five to 40 years, the most significant being those offered on its installed single-ply roofing systems primarily in the United States, subject to certain exclusions, that covers leaks in the roofing system attributable to a problem with the particular product or the installation of the product. Strategy Our strategy for the CCM segment is to: • Leverage mega trends around energy efficiency, labor savings, and the re-roofing cycle supported by initiatives to accelerate innovation, and the Carlisle Experience; • Continue to support its above average margin profile through COS; and • Further expand our offering of innovative solutions to U.S. commercial roofing markets, including broadening our product breadth and geographic reach into architectural metals. 4

Table of Contents Key growth initiatives include: • Grow profitability through the creation of value, based on labor and energy efficiency; • Continue to drive and leverage the Carlisle Experience to deliver superior customer service; • Drive innovation through enhanced focus on research and development to continue to introduce proprietary, differentiated, value-add products and solutions; • Continue to invest in training employees and customers to drive a culture of continuous learning that creates brand loyalty; and • Focus mergers and acquisitions on synergistic building envelope opportunities. Carlisle Weatherproofing Technologies (“CWT”) Products, Markets and Locations CWT is a leading provider of high-performance waterproofing and moisture protection products, protective roofing underlayments, integrated air and vapor barriers, spray polyurethane foam and coating systems, and block-molded expanded polystyrene insulation and other insulation products for the building envelope. CWT offers an enhanced set of solutions and systems to aid in the design of efficient building envelope construction projects, backed by industry-leading product innovations and a focus on environmentally responsible principles. CWT operates manufacturing facilities and distribution locations throughout the United States and Canada, its primary markets. The majority of CWT’s products are sold through distribution and retail outlets throughout North America. Key Raw Materials Key raw materials for this segment include MDI, silicone polymer, asphalt, glass mat, styrene and expanded polystyrene insulation bead. These raw materials generally have at least two vendor sources. The vendor typically has multiple processing facilities for key raw materials that are single sourced. Seasonality Revenues and earnings for CWT have historically been higher in the second and third quarters due to increased construction activity during those periods from favorable weather conditions. Market Factors This segment faces competition from numerous, usually local or regional competitors, that typically produce a subset of CWT’s broader suite of weatherproofing technologies used in both commercial and residential markets. The level of competition within these markets varies by product line, region and channel. As a leader in air and vapor barriers, waterproofing, spray foam and other insulation solutions, CWT competes through innovative products, long-term warranties and customer service. CWT's backlog of orders is not a significant factor for the segment, and thus not a reliable indicator of intermediate-term revenue as most products have relatively short order-to-delivery periods. The warranties offered on CWT products vary by solution. Strategy Our strategy for the CWT segment is to: • Further expand our value proposition to building owners, contractors and home builders with our comprehensive suite of energy-efficient building products; • Capture significant aftermarket opportunities as both residential and non-residential buildings are in need of both repair and energy-efficiency upgrades; • Continue to expand margins through implementation of COS, strong incremental margins on volume growth and investments in our factories; and • Further expand our presence in niche high-growth and high-margin opportunities including retail product expansion, advanced air, water, and vapor barriers, and enhancement of other building envelope adjacencies. 5

Table of Contents Key growth initiatives include: • Drive sales and commercial excellence using system and bundle sales to leverage enhanced product breadth and the Carlisle Experience; • Accelerate innovation to develop new integrated system solutions across the building envelope; • Grow profitability through the creation of value, based on labor and energy efficiency, and leveraging COS throughout CWT’s manufacturing footprint; • Continue development of proprietary, differentiated products; • Utilize training to drive a culture of continuous learning that creates brand loyalty; and • Focus mergers and acquisitions on synergistic building envelope opportunities. Compliance with Government Regulations We are subject to various government regulations, including environmental regulations. To date, our costs of complying with these regulations have not had a material effect on our capital expenditures, earnings or competitive position of any business segment. We do not expect to incur any material capital expenditures for environmental control facilities for the current fiscal year or any other subsequent period. Sustainability Carlisle’s sustainability history is fundamental to our culture. Our journey began in the early 1900s when we recycled rubber from our first inner tube production line, and now, over 100 years later, we consider sustainability a core attribute of the value we provide our customers. We believe our century-long legacy of responsible stewardship will help enable us to meet our net- zero GHG emission goal through the three pillars of our sustainability strategy: producing energy-efficient products, reducing our operational and value-chain emissions, and diverting construction material waste from landfills. Innovation is a fundamental practice at Carlisle, and we believe that it is integral to our ability to achieve both our economic and sustainability goals aligned through Vision 2030. The growing demand for energy and labor-saving efficiencies, as well as increased preference for full building envelope solutions creates opportunities for Carlisle to provide new, innovative solutions that create value for both our customers and the environment. In recognition of these trends, we have committed to increasing our investment in research and development as part of our Vision 2030 strategy. Our environmental sustainability initiatives and strategy are discussed further in our 2024 Corporate Sustainability Report, which can be found on our website at www.carlisle.com; this report is not incorporated by reference and should not be considered part of this Annual Report on Form 10-K. Human Capital Resources As of December 31, 2025, we employed approximately 5,900 people, including approximately 4,800 employees in our U.S operations and excluding approximately 300 contractors. Approximately 500 of our employees, including international locations, were represented by unions under contracts that expire at varying times in the future. We believe we maintain good relations with all employees and their unions. We believe that the attraction, development, and retention of talent are critical to our ability to achieve our strategy, and a trained, diverse, and inspired workforce is integral to delivering value to our stakeholders. Our recruiting process is designed to reach a broad and diverse pool of candidates through specialized outreach and partnerships. We collaborate with universities in the U.S. and internationally to attract talent across key functions such as management, sales, finance, and information technology. Each business segment also works with local high schools and trade schools to promote manufacturing careers and build future workforce pipelines. We maintain a policy of non-discriminatory treatment and respect of human rights for all current and prospective employees. Additionally, Carlisle offers several training programs to current employees intended to recognize and develop the careers of employees across all levels. Health and safety remain a core commitment, and we maintain programs designed to support a safe and productive work environment. See our website at www.carlisle.com, for further discussion of our employee benefits and talent development programs.

Table of Contents Item 1A. Risk Factors. The Company’s business, financial condition, results of operations or cash flows can be affected by a number of factors, including those material factors set forth below, those set forth in our “Forward Looking Statements” disclosure in Item 7 and those set forth elsewhere in this Annual Report on Form 10-K, any one of which could cause the Company’s actual results to vary materially from recent results or from anticipated future results and make an investment in the Company speculative or risky. Strategic, Business and Operational Risks The Company’s growth strategy is partially dependent on the acquisition and successful integration of other businesses. A key pillar of the Company’s Vision 2030 strategic plan is building scale with synergistic acquisitions. When companies become available for purchase, the process is often highly competitive, which tends to result in relatively high valuations for the target company. There can be no assurance that the Company will be able to continue to identify, negotiate and finance suitable acquisitions at values the Company considers reasonable. Acquisitions involve numerous risks, including the failure to realize expected revenue growth and/or operating and cost synergies from integration initiatives, an increased dependency on the markets served, the diversion of management’s attention from its existing operations or increased debt to finance the acquisitions. The successful realization of revenue growth, cost reductions and synergies and increases in profitability overall are dependent upon successful integration initiatives. If these integration initiatives are not fully realized, there may be a negative effect on the Company’s business, financial condition, results of operations or cash flows, including goodwill and/or intangible asset impairments, which may be material. The loss of, a significant decline in business with, or pricing pressure from, one or more of the Company’s key customers could adversely affect the Company’s business, financial condition, results of operations or cash flows. The Company's CCM segment operates in several niche markets in which a large portion of the segment’s revenues are attributable to a few large customers. These markets have experienced recent consolidation among distributors of roofing materials and complementary building products. A significant reduction in purchases by one or more of these customers could have an adverse effect on the business, financial condition, results of operations or cash flows of one or more of the Company’s segments. Some of the Company’s key customers enjoy significant purchasing power that may be used to exert pricing pressure on the Company. Additionally, as many of the Company’s businesses are part of a long supply chain to the ultimate consumer, the Company’s business, financial condition, results of operations or cash flows could be adversely affected if one or more key customers elects to in-source or find alternative suppliers for the production of a product or products that the Company currently provides. The Company could be adversely affected by any significant damage to, or prolonged disruption of, our manufacturing facilities. The Company has made substantial investments in manufacturing facilities, and many products are produced at a limited number of locations. These facilities could be materially damaged or operations at these facilities could be materially disrupted by natural disasters, such as floods, tornados, hurricanes, fires and earthquakes, as well as governmental or administrative actions, regulatory issues, civil unrest, industrial accidents, unavailability or excessively high cost of raw materials, mechanical equipment failure, human error, cybersecurity breaches, widespread health emergencies, theft, sabotage or other reasons. We could incur uninsured losses and liabilities arising from such events, including damage to our reputation, or suffer material losses in operational capacity, which could have a material adverse impact on our business, financial condition, results of operations or cash flows. The development and introduction of new products, or the failure to do so, could have a material adverse effect on our business, financial condition, results of operations or cash flows. A key pillar of the Company’s Vision 2030 strategic plan is driving growth through continued investment in new product innovation. Our likelihood of success in investing in new products must be considered in light of the expenses, difficulties and delays frequently encountered in connection with the early phases of new product development, including the difficulties involved in obtaining permits and regulatory approvals, planning and constructing new manufacturing facilities, and establishing, maintaining or expanding customer relationships. While 7
Page 8
Table of Contents we strive to introduce new products, our efforts to develop and market new products may be unsuccessful or unprofitable, which could adversely affect our business, financial condition, results of operations or cash flows. Industry and Macroeconomic Risks Several of the market segments that the Company serves are cyclical and sensitive to domestic and global economic conditions. Several of the market segments in which the Company sells its products are, to varying degrees, cyclical and may experience periodic downturns in demand. For example, the CCM and CWT segments are susceptible to downturns in the commercial construction industry, particularly in the construction repair and replacement sectors, and the CWT segment is susceptible to downturns in the residential construction industry. Uncertainty regarding global economic conditions may have an adverse effect on the businesses, results of operations and financial condition of the Company and its customers, distributors and suppliers. Among the economic factors which may affect performance are: manufacturing activity, commercial and residential construction, difficulties entering new markets and general economic conditions such as inflation, deflation, interest rates, tariffs and credit availability. These effects may, among other things, negatively impact the level of purchases, capital expenditures and creditworthiness of the Company’s customers, distributors and suppliers, and therefore, the Company’s results of operations, margins and orders. The Company cannot predict if, when or how much worldwide economic conditions will fluctuate. These conditions are highly unpredictable and beyond the Company's control. If these conditions deteriorate, however, the Company’s business, financial condition, results of operations or cash flows could be adversely affected. The Company has significant concentrations in the construction market. Most of the Company’s revenues and operating income are generated from the construction market. Construction spending is affected by economic conditions, changes in interest rates, inflationary pressures, demographic and population shifts, new housing starts, impacts on labor availability from U.S. immigration laws, policies and practices and changes in construction spending by federal, state and local governments. A decline in the construction market, particularly in construction repair and replacement activities, could adversely affect the Company’s business, financial condition, results of operations or cash flows. Additionally, adverse weather conditions such as heavy or sustained rainfall, cold weather and snow can limit construction activity and reduce demand for roofing materials. The CCM and CWT segments compete through pricing, among other factors. Competition in these segments may increase pricing pressure on the Company, which may negatively affect operating results in future periods. Raw material costs are a significant component of the Company’s cost structure and are subject to volatility, including cost increases, significant disruptions to the Company's supply chains or significant shortages of materials. The Company utilizes petroleum-based products, chemicals, resins and other commodities in its manufacturing processes. Raw materials, including inbound freight, accounted for approximately 66% of the Company’s cost of goods sold in 2025. Significant increases in the costs of these materials may not be recovered through selling price increases and significant disruption to the Company's supply chains or significant shortages of materials could adversely affect the Company’s business, financial condition, results of operations or cash flows. The Company also relies on global sources of raw materials, which could be adversely impacted by unfavorable shipping or trade arrangements, including import and export tariffs and global economic conditions. Environmental, Regulatory and Legal Risks The Company's operations are subject to risks related to environmental laws and regulations. We are subject to stringent environmental laws and regulations, including those relating to air emissions, wastewater discharges, and chemical and hazardous waste management and disposal. Some of these environmental laws hold owners or operators of land or businesses liable for their own and for previous owners’ or operators’ releases of hazardous or toxic substances or wastes. Other environmental laws and regulations require the obtainment of, and compliance with, environmental permits. To date, costs of complying with environmental, health and safety requirements have not been material, and the Company did not have any significant accruals related to potential future costs of environmental remediation as of December 31, 2025 and 2024, nor are any material asset retirement obligations recorded as of those dates. However, the nature of the Company’s operations 8
Page 9
Table of Contents and its long history of industrial activities at certain of its current or former facilities, as well as those acquired, could potentially result in material environmental liabilities or asset retirement obligations. Global climate change and related regulations could negatively affect the Company. Changes in environmental and climate change laws or regulations, including laws relating to GHG emissions, could lead to new or additional investment in the Company’s products or facilities and could increase environmental compliance expenditures. Changes in climate change concerns including GHG emissions, and the regulation of such concerns including climate-related disclosures, could subject the Company to additional costs and restrictions, including increased energy and raw material costs and other compliance requirements which could negatively impact the Company’s reputation, business, capital expenditures, results of operations and financial position. We have made several public commitments regarding our intended reduction of GHG emissions, including commitments to achieve net zero GHG emissions by 2050 and the establishment of science-based targets to reduce GHG emissions from our operations and the operations of our value chain. Although we intend to meet these commitments, we may be required to expend significant resources to do so, which could increase our operational costs. Further, there can be no assurance of the extent to which any of our commitments will be achieved, or that any future investments we make in furtherance of achieving such targets and goals will meet investor expectations or any binding or non-binding legal standards regarding sustainability performance. Moreover, we may determine that it is in the best interest of the Company and our stockholders to prioritize other business, social, governance or sustainable investments over the achievement of our current commitments based on economic, regulatory and social factors, business strategy or pressure from investors, activist groups or other stakeholders. If we are unable to meet these commitments, then we could incur adverse publicity and reaction from investors, activist groups and other stakeholders, which could adversely impact the perception of our brands and our products and services by current and potential customers, as well as investors, which could in turn adversely impact our results of operations. Cybersecurity breaches or significant disruptions of our information technology systems, increased compliance costs or violations of data privacy laws could adversely affect our business. We rely on information technology systems, some of which are managed by third parties, to process, transmit and store electronic information, and to manage or support critical business processes. Security breaches of these systems could result in the unauthorized or inappropriate access to confidential information or personal data entrusted to us by our business partners. While we have experienced, and expect to continue to experience, cybersecurity breaches of our information technology systems, none of the breaches to date has had a material impact on the Company. Additionally, these systems may be disrupted as a result of attacks by computer hackers or viruses, human error or wrongdoing, operational failures or other catastrophic events. Cyber threats and the techniques used in cyberattacks change, develop and evolve rapidly, including from emerging technologies, such as advanced forms of artificial intelligence. The Company leverages its internal information technology infrastructures, and those of its business partners, to enable, sustain and protect its global business interests. However, any of the aforementioned breaches or disruptions or the impacts from changing technologies, including artificial intelligence, could result in legal claims, liability or penalties under privacy laws or damage to operations or to the Company's reputation, which could adversely affect our business. We are subject to data privacy and security laws, regulations and customer-imposed controls as a result of having access to and processing confidential, personal and/or sensitive data in the ordinary course of business. If we are unable to maintain reliable information technology systems and appropriate controls with respect to privacy and security requirements, we may suffer regulatory consequences that could be costly or otherwise adversely affect our business. New laws that may restrict use or sharing of data or otherwise regulate artificial intelligence and machine learning may also lead to significant increases in the Company's cost of compliance or otherwise adversely affect our business. The Company could face product liability claims, and we may not have sufficient insurance to cover those claims. Our building products are used in a wide variety of commercial, residential and industrial applications. We face an inherent risk of exposure to product liability or other claims in the event our products are alleged to be defective or that the use of our products is alleged to have resulted in harm to others or their property. If product liability lawsuits against us are successful, it could have an adverse impact on our financial condition and results of operations. Moreover, any such lawsuits, whether or not successful, could result in adverse publicity to us, which could harm our reputation and cause our sales to decline. We maintain insurance coverage to protect us against product liability 9
Page 10
Table of Contents claims, but that coverage may not be adequate to cover all claims that may arise, or we may not be able to maintain adequate insurance coverage in the future at an acceptable cost. Any liability not covered by insurance or that exceeds our established reserves could materially and adversely impact our business, financial condition and results of operations. Item 1B. Unresolved Staff Comments. None. Item 1C. Cybersecurity. The Company’s processes to assess, identify, and manage material cybersecurity risks are included as part of the Company’s overall risk management program and include documented procedures and protocols to identify and monitor material cybersecurity risks, provide cybersecurity training and awareness, implement protective controls, and established incident response procedures. The Company also engages third-party professional cybersecurity consultants to assist with its cybersecurity processes, including conducting periodic tabletop exercises and system penetration testing. The Company maintains processes to oversee and identify certain risks from cybersecurity threats associated with its use of these third- party service providers and maintains protections in its vendor risk management process. Risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected, nor are reasonably likely to materially affect, the Company, including its business strategy, results of operations, or financial condition. The Audit Committee of the Company’s Board of Directors oversees the assessment and management of the Company’s major financial risk exposures, including cybersecurity risk, and reviews the steps management has taken to monitor, control and mitigate such exposures. No less than annually, the Senior Director of Information Security and Data Privacy attends an Audit Committee meeting and presents for review and discussion the Company’s processes to assess, identify, manage and mitigate material cybersecurity risks. The Audit Committee subsequently reports on the presentation to the full Board of Directors. The Company’s cybersecurity processes are managed by a dedicated department led by the Senior Director of Information Security and Data Privacy. The Director of Information Security has 12 years of cybersecurity work experience and carries a number of cybersecurity and security-related certifications. The dedicated department is responsible for developing and implementing the strategies, policies and procedures to manage and mitigate cybersecurity risks. The dedicated department utilizes documented incident response procedures to become informed of and monitor the prevention, detection, mitigation and remediation of cybersecurity incidents. The dedicated department is comprised of an 11 person staff who carry myriad cybersecurity, privacy, and other security-related certifications. The Company’s internal audit department also provides support to the Company’s cybersecurity processes. Item 2. Properties.

Table of Contents Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. Carlisle Companies Incorporated (“Carlisle,” the “Company,” “we,” “us” or “our”) is a leading supplier of innovative building envelope products and solutions for more energy-efficient buildings. Through our building products businesses, Carlisle Construction Materials ("CCM") and Carlisle Weatherproofing Technologies ("CWT"), and family of leading brands, we deliver innovative, labor-reducing and environmentally responsible products and solutions to customers through the Carlisle Experience. Carlisle is committed to generating superior stockholder returns and maintaining a balanced capital deployment approach, including investments in our businesses, strategic acquisitions, share repurchases and continued dividend increases. Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is designed to provide a reader of our financial statements with a narrative from the perspective of Company management. All references to “Notes” refer to our Notes to Consolidated Financial Statements in this Annual Report on Form 10-K. For more information regarding our consolidated results, segment results, and liquidity and capital resources for the year ended December 31, 2024, as compared to the year ended December 31, 2023, refer to "Part II—Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations" in the Company's 2024 Annual Report on Form 10-K (the "2024 Annual Report on Form 10-K"). Executive Overview Throughout 2025, despite continued headwinds in new construction and a complex economic environment, we continued to execute against our Vision 2030 strategy, and we remain very confident in our ability to achieve our Vision 2030 financial objectives. Over the course of the year, we made progress on all our key pillars of Vision 2030. We increased investments in innovation to develop new market-leading products. We enhanced our emphasis on the Carlisle Operating System ("COS") and expanded automation in our factories to drive operational excellence. We added significant management talent and further elevated the Carlisle Experience to strengthen customer loyalty and service. And above all else, we continued to deliver on our commitment to being superior capital allocators. Carlisle’s performance during 2025 adds to our history of resilience through the economic cycles and challenges we have faced over the years, such as the Covid pandemic. We delivered another solid year of cash flow, generating over $1 billion of operating cash flow, which continued to provide balance sheet optionality. As the M&A environment in 2025 was challenging, we turned a significant portion of that cash flow to share repurchases, as we continued to see this as a solid opportunity for capital deployment. At CCM, solid re-roofing demand, which represents approximately 70% of our commercial roofing business, continued to help stabilize our business as new construction markets work through the bottom of the cycle. At CWT, our recent acquisitions and operational initiatives contributed to revenue growth, and we are well-positioned to capitalize on the growing need for energy- efficient weatherproofing solutions. North America is the most attractive building-products market globally, supported by strong, long-term fundamentals including the demand for energy-efficient solutions, the need to improve labor productivity, and the recurring maintenance requirements of an aging non-residential building stock—over 70% of which is more than 25 years old. Buildings are a critical and indispensable component of the physical economy. They must be built, maintained, and continuously improved. This structural reality reinforces the durability and necessity of our end markets. Carlisle’s imperative business continues to benefit from a strong re-roofing market, and we continued to benefit from our position as a North American leader in the world’s largest building-products market. Carlisle’s leadership position in this essential market, highly responsive cost structure combined with the discipline of COS and our proven capital allocation framework, continues to translate into superior and sustainable margin performance. While we expect the current challenging market conditions to continue into the first half of 2026, our solid financial position, robust cash flow, and ongoing commitment to operational excellence enable us to continue generating strong returns, pursue value-enhancing acquisitions, and deliver shareholder value. 13

CCM’s revenue increased in 2025 primarily driven by strong re-roofing activity aided by the MTL acquisition partially offset by lower new construction activity. CCM's operating margin and adjusted EBITDA for 2025 decreased primarily due to higher operating costs of $56.3 million, primarily to enhance the Carlisle Experience, and increased research and development expenses of $8.7 million. Carlisle Weatherproofing Technologies This segment produces building envelope solutions that drive energy efficiency and sustainability in commercial and residential applications. Products include high-performance waterproofing and moisture protection products, protective roofing underlayments, fully integrated liquid and sheet applied air/vapor barriers, sealants/primers and flashing systems, roof coatings and mastics, spray polyurethane foam and coating systems for a wide variety of thermal protection applications and other premium polyurethane products, block-molded expanded polystyrene (1) (1) (1) 15

CWT’s revenue decrease in 2025 was primarily the result of lower sales volumes due to continued softness in new construction activity, mostly offset by the acquisitions of PFB, ThermaFoam, and Bonded Logic. CWT’s operating margin and adjusted EBITDA margin decrease in 2025 primarily reflected increased unit costs resulting from higher absorption of fixed costs on lower volumes. Liquidity and Capital Resources We believe that our current cash reserves, available credit facilities, including borrowings available under our $1.0 billion Fifth Amended and Restated Credit Agreement, and anticipated operating cash flows are adequate to meet our short-term projected business requirements for at least the next 12 months and our long-term financial requirements, including the repayment of outstanding principal balances on existing notes by their respective maturity dates. Additional sources of liquidity may be obtained through access to the capital markets, subject to market conditions. The Company may consider such access for purposes that include the repayment of outstanding debt and the funding of acquisitions. For further details regarding long-term debt, refer to Note 13. Management retains discretion over the allocation of available cash and may deploy resources toward capital expenditures, acquisitions, strategic investments, dividends, or share repurchases. (in millions) 2025 2024 Net cash provided by operating activities $ 1,101.8 $ 1,030.3 Net cash provided by (used in) investing activities (240.4) 1,229.6 Net cash provided by (used in) financing activities (503.7) (2,110.2) Effect of foreign currency exchange rate changes on cash 0.9 (1.7) Change in cash and cash equivalents $ 358.6 $ 148.0 Operating Activities Net cash provided by operating activities in 2025 was $1.1 billion, an increase of $71.5 million compared to 2024, primarily due to lower working capital uses of $115.7 million, partially offset by lower income from continuing operations, excluding non- cash reconciling items, of $33.8 million. Inventory has remained steady throughout 2025, resulting in a $136.9 million decrease in working capital uses compared to 2024, which experienced higher investment in inventory due to the end of destocking from 2023 followed by increased construction activity. Additionally, working capital used in other current liabilities decreased by $90.4 million in 2025 compared to 2024, primarily due to the timing of tax expenses and payments. These reductions in working capital uses were partially offset by an additional $73.0 million in working capital used in accounts receivable due to timing of sales and an additional $28.9 million used in accounts payable due to timing of expenses and payments when comparing 2025 to 2024. Investing Activities Net cash used in investing activities in 2025 was $240.4 million, primarily attributable to the acquisition of ThermaFoam for $53.7 million, the acquisition of Bonded Logic for $61.4 million, and capital expenditures of $131.2 million.

Page 17
Table of Contents Net cash provided by investing activities in 2024 was $1.2 billion, primarily attributable to net cash proceeds of $2.0 billion from the sale of Carlisle Interconnect Technologies ("CIT"), partially offset by use of an aggregate of $676.9 million to fund the acquisitions of MTL and PFB and capital expenditures of $113.3 million. Financing Activities Net cash used in financing activities in 2025 was $503.7 million, primarily attributable to share repurchases of $1.3 billion and cash dividend payments of $181.1 million. These outflows were partially offset by proceeds totaling $987.8 million from the issuance of the 2035 Notes and 2040 Notes. Net cash used in financing activities in 2024 was $2.1 billion, which primarily reflected share repurchases of $1.6 billion, the redemption of the 2024 Notes of $400.0 million and cash dividend payments of $172.4 million. Critical Accounting Estimates Our significant accounting policies are more fully described in Note 1. In preparing the Consolidated Financial Statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”), the Company’s management must make informed decisions which impact the reported amounts and related disclosures. Such decisions include the selection of the appropriate accounting principles to be applied and assumptions on which to base estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates, including those related to business combinations, goodwill and indefinite-lived intangible assets, and income taxes on an ongoing basis. The Company bases its estimates on historical experience, terms of existing contracts, our observation of trends in the industry, information provided by our customers and information available from other outside sources, that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Business Combinations As noted in "Item 1. Business. Business Strategy", we have a history and a strategy of acquiring businesses. We account for these business combinations as required by GAAP under the acquisition method of accounting, which requires us to recognize the assets acquired and the liabilities assumed at their acquisition date fair values. Deferred taxes are recorded for any differences between fair value and tax basis of assets acquired and liabilities assumed and can vary based on the structure of the acquisition as to whether it is a taxable or non-taxable transaction. To the extent the purchase price of the acquired business exceeds the fair values of the assets acquired and liabilities assumed, including deferred income taxes recorded in connection with the transaction, such excess is recognized as goodwill (see further below for our critical accounting estimate regarding post-acquisition accounting for goodwill). The most critical areas of judgment in applying the acquisition method include selecting the appropriate valuation techniques and assumptions that are used to measure the acquired assets and assumed liabilities at fair value, particularly for intangible assets, contingent consideration, acquired tangible assets such as property, plant and equipment, and inventory. 17
Page 18
Table of Contents The key techniques and assumptions utilized by type of major acquired asset or liability generally include: Asset/Liability Typical Valuation Technique Key Assumptions Technology-based intangibleassets Relief from royalty method • Estimated future revenues from acquired technology • Royalty rates that would be paid if licensed from a third-party • Discount rates Customer-based intangibleassets Multiple-period excess earnings method • Estimated future revenues from existing customers • Rates of customer attrition • EBITDA margins • Discount rates • Contributory asset charges Trademark/trade nameintangible assets Relief from royalty method • Estimated future revenues from acquired trademark/trade name • Economic useful lives (definite vs. indefinite) • Royalty rates that would be paid if licensed from a third-party • Discount rates Property, plant & equipmentMarket comparable transactions (real property) andreplacement cost, new less economic depreciation(personal property) • Similarity of subject property to market comparable transactions • Costs of like equipment in new condition • Economic obsolescence rates Inventory Net realizable value less (i) estimated costs ofcompletion and disposal, and (ii) a reasonable profitallowance for the seller • Estimated percentage complete (WIP inventory) • Estimated selling prices • Estimated completion and disposal costs • Estimated profit allowance for the seller Contingent considerationDiscounted future cash flows • Future revenues and/or net earnings• Discount rates In selecting techniques and assumptions noted above, we generally engage third-party, independent valuation professionals to assist us in developing the assumptions and applying the valuation techniques to a particular business combination transaction. In particular, the discount rates selected are compared to and evaluated with (i) the industry weighted-average cost of capital, (ii) the inherent risks associated with each type of asset and (iii) the level and timing of future cash flows appropriately reflecting market participant assumptions. As noted above, goodwill represents a residual amount of purchase price. However, the primary items that generate goodwill include the value of the synergies between the acquired company and our existing businesses and the value of the acquired assembled workforce, neither of which qualifies for recognition as an intangible asset. Refer to Note 3 for more information regarding business combinations, specifically the items that generated goodwill in our recent acquisitions. Subsequent Measurement of Goodwill Goodwill is not amortized but is tested for impairment annually, or more often if impairment indicators are present, at a reporting unit level. Goodwill is tested for impairment via a one-step process by comparing the fair value of goodwill with its carrying value. We recognize an impairment for the amount by which the carrying amount exceeds the fair value. We estimate the fair value of our reporting units based on the income approach utilizing the discounted cash flow method and the market approach utilizing the public company market multiple method. The key techniques and assumptions generally include: Valuation Technique Key Assumptions Discounted future cash flows • Estimated future revenues• EBITDA margins• Discount rates Market multiple method • Peer public company group• Financial performance of reporting units relative to peer public company group 18

Table of Contents We have determined that we have four reporting units and have allocated goodwill to those reporting units as follows: (in millions) December 31,2025 December 31,2024 Carlisle Construction Materials - Commercial Roofing $ 848.9 $ 848.9 Carlisle Construction Materials - Architectural Metals 201.0 200.5 Carlisle Construction Materials - Europe 29.0 23.8 Carlisle Weatherproofing Technologies 460.0 404.8 Total $ 1,538.9 $ 1,478.0 Annual Impairment Test We test our goodwill for impairment annually as of November 1. For the November 1, 2025 impairment test, all reporting units were tested for impairment using a qualitative approach. Under this approach, an entity may assess qualitative factors as well as relevant events and circumstances to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The results of our analysis indicated that it is not more likely than not that the fair value of the aforementioned reporting units were less than their carrying values and thus, a quantitative analysis was not performed. We will continue to closely monitor actual results against expectations and assess whether any significant changes in current events or conditions alter our projections for estimated future cash flows, discount rates, and market multiples. While we believe our conclusions regarding the fair value estimates of our reporting units are appropriate, these estimates are inherently uncertain and involve various judgments and assumptions. Factors influencing these estimates include the growth rate and extent in the markets served by our reporting units, the realization of future sales price and volume increases, fluctuations in exchange rates, fluctuations in price and availability of key raw materials, future operating efficiencies and, with respect to discount rates, volatility in interest rates and the cost of equity. Refer to Note 11 for more information regarding goodwill. Subsequent Measurement of Indefinite-Lived Intangible Assets As discussed above, indefinite-lived intangible assets are recognized and recorded at their acquisition-date fair value. Intangible assets with indefinite useful lives are not amortized but are tested for impairment annually, or more often if impairment indicators are present, at the appropriate unit of account, which is generally the individual asset. Indefinite-lived intangible assets are tested for impairment via a one-step process by comparing the fair value of the intangible asset with its carrying value. We recognize an impairment charge for the amount by which the carrying amount exceeds the intangible asset's fair value. We generally estimate the fair value of our indefinite-lived intangible assets consistent with the techniques noted above using our expectations about future cash flows, discount rates and royalty rates for purposes of the annual test. We monitor for significant changes in those assumptions during interim reporting periods. We also periodically re-assess indefinite-lived intangible assets as to whether their useful lives can be determined, and if so, we would begin amortizing any applicable intangible asset. Annual Impairment Test We test our indefinite-lived intangible assets for impairment annually as of November 1. For the November 1, 2025 impairment test, all indefinite-lived intangible assets, except for the Henry trade name related to ASP Henry Holdings, Inc., which we acquired in 2021, within the CWT reportable segment, were tested for impairment using the qualitative approach. The Henry trade name, with an aggregate carrying value of $219.0 million, was tested for impairment using the quantitative approach described above, resulting in a fair value that exceeded its carrying value by less than 10%. We will continue to closely monitor actual results against expectations and assess whether any significant changes in current events or conditions alter our projections about future estimated revenues and discount rates. If our expectations of revenues from this trade name do not materialize or if the discount rate increases (based on increases in interest rates, market rates of return or market volatility), we may be required to record intangible asset impairment charges, which may be material. Refer to Note 11 for more information regarding intangible assets. 19

Table of Contents Income Taxes Our income tax expense, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect management’s best estimate of current and future taxes to be paid. We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgments and estimates are required in the determination of the consolidated income tax expense. Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and amounts reported in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to recover our deferred tax assets in the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and results of recent operations. We believe that it is more likely than not that the benefit from certain U.S. federal, state and foreign net operating loss, and credit carryforwards will not be realized. In recognition of this risk, we have provided a valuation allowance of $52.0 million on the deferred tax assets related to these carryforwards. We (1) record unrecognized tax benefits as liabilities in accordance with Accounting Standards Codification 740, Income Taxes, and (2) adjust these liabilities when our judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the unrecognized tax benefit liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available. Non-GAAP Financial Measures EBIT, Adjusted EBIT, Adjusted EBITDA and Adjusted EBITDA Margin Earnings before interest and taxes ("EBIT"), adjusted EBIT, adjusted earnings before interest, taxes, depreciation and amortization ("EBITDA") and adjusted EBITDA margin are intended to provide investors and others with information about our performance and our segments' performance without the effect of items that, by their nature, tend to obscure core operating results due to potential variability across periods based on the timing, frequency and magnitude of such items. As a result, management believes that these measures enhance the ability of investors to analyze trends in our business and evaluate our performance relative to similarly-situated companies. This information differs from net income, operating income, and operating margin determined in accordance with GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with GAAP. Our and our segments' EBIT, adjusted EBIT, adjusted EBITDA and adjusted EBITDA margin follows.

Table of Contents Forward-Looking Statements This Annual Report on Form 10-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally use words such as "expect," "foresee," "anticipate," "believe," "project," "should," "estimate," "will," "plans," "intends," "forecast," and similar expressions, and reflect our expectations concerning the future. Such statements are made based on known events and circumstances at the time of publication and, as such, are subject in the future to unforeseen risks and uncertainties. It is possible that our future performance may differ materially from current expectations expressed in these forward-looking statements, due to a variety of factors such as: increasing price and product/service competition by foreign and domestic competitors, including new entrants; technological developments and changes; the ability to continue to introduce competitive new products and services on a timely, cost- effective basis; our mix of products/services; increases in raw material costs that cannot be recovered in product pricing; domestic and foreign governmental and public policy changes including environmental and industry regulations; the ability of our customers to maintain appropriate labor levels under U.S. immigration laws, policies and practices; the ability to meet our goals relating to our intended reduction of greenhouse gas emissions, including our net zero commitments; threats associated with and efforts to combat terrorism; protection and validity of patent and other intellectual property rights; the identification of strategic acquisition targets and our successful completion of any transaction and integration of our strategic acquisitions; our successful completion of strategic dispositions; the cyclical nature of our businesses; the impact of information technology, cybersecurity, artificial intelligence or data security breaches at our businesses or third parties; the outcome of pending and future litigation and governmental proceedings; and the other factors discussed in the reports we file with or furnish to the Securities and Exchange Commission from time to time. In addition, such statements could be affected by general industry and market conditions and growth rates, the condition of the financial and credit markets and general domestic and international economic conditions, including inflation, interest rate and currency exchange rate fluctuations, and tariffs. Further, any conflict in the international arena, including the Russian invasion of Ukraine and war in the Middle East, may adversely affect general market conditions and our future performance. Any forward-looking statement speaks only as of the date on which that statement is made, and we undertake no duty to update any forward-looking statement to reflect events or circumstances, including unanticipated events, after the date on which that statement is made, unless otherwise required by law. New factors emerge from time to time, and it is not possible for management to predict all of those factors, nor can it assess the impact of each of those factors on the business. Item 7A. Quantitative and Qualitative Disclosures About Market Risk. We are exposed to market risk in the form of changes in interest rates, foreign currency exchange rates and commodity prices for raw materials. We may, from time to time, enter into derivative financial instruments to manage these risks; however, we do not utilize such instruments or contracts for speculative or trading purposes. In the event that we enter into a derivative financial instrument, it is possible that such future dated contracts could no longer serve as a hedge if the projected cash flow does not occur as anticipated at the time of contract initiation. Interest Rate Risk We are exposed to interest rate risks as a result of our borrowing and investing activities, which principally includes long-term borrowings used to maintain liquidity and to fund our business operations and capital requirements. We may enter into interest rate swaps from time to time to manage our mix of fixed and variable interest rate debt effectively. We may enter into other interest rate derivatives such as treasury locks or zero cost collars to manage forecasted interest rates associated with bond offerings. As of December 31, 2025, and 2024, there were no interest rate swaps or other derivative instruments in place and, at both dates, all of our long-term debt was fixed-rate and U.S. Dollar denominated. The Credit Agreement also allows for borrowings of up to $1.0 billion at a variable interest rate. We had no outstanding borrowings under this facility as of December 31, 2025, and 2024. The nature and amount of our long-term debt may vary from time to time as a result of business requirements, market conditions and other factors. We consider the risk to our results of operations from changes in market rates of interest to be minimal as our interest bearing debt instruments are fixed-rate. 22
Page 23
Table of Contents Foreign Currency Exchange Risk A portion of our operating cash flows are denominated in foreign currencies. As such we are exposed to market risk from changes in foreign currency exchange rates. We are primarily exposed to the exchange rates of currencies including the Canadian Dollar, Euro, British Pound and Chinese Renminbi. We continually evaluate our foreign currency exposure based on current market conditions and the locations in which we conduct our business. We manage most of our foreign currency exposure on a consolidated basis, which allows us to net certain exposures and take advantage of natural offsets. In order to mitigate foreign currency risk, we may, from time to time, enter into derivative financial instruments, generally foreign currency forward contracts, to hedge the cash flows related to certain foreign currency denominated sales and purchase transactions expected in the near term and the related recognized trade receivable or payable. The gains and losses on these contracts offset changes in the value of the related exposures. It is our policy to enter into foreign currency derivative financial instruments only to the extent considered necessary to meet the objectives set forth above. We generally do not hedge the risk of foreign currency net investments into U.S. Dollars for financial reporting. The near-term sensitivity of these contracts to changes in foreign currency exchange rates is also minimal as they are scheduled to mature within 12 months. Further, changes in the fair value of these contracts will be offset by changes in the cash flows of the underlying foreign currency denominated sales, purchases, assets and liabilities which the contracts are intended to mitigate (both accounting and economic hedges). Commodity Price Risk We continually address the impact of changes in commodity prices on our results of operations and cash flow. Our exposure to changes in commodity prices is principally indirect as we do not directly purchase exchange-traded commodities, but rather purchase raw materials that are a result of further downstream processing (as noted in Item 1 of this Form 10-K), primarily inputs resulting from processing petroleum-based products, chemicals and resins. We generally manage the risk of changes in commodity prices that impact our raw material costs by seeking to (i) offset increased costs through increases in prices, (ii) alter the nature and mix of raw materials used to manufacture our finished goods or (iii) enter into commodity-linked sales or purchase contracts, all to the extent possible based on competitive and other economic factors. We may also from time to time enter into derivative financial instruments to mitigate such impact; however, as of December 31, 2025, and 2024, we had no derivative financial instruments in place. 23

Table of Contents Item 8. Financial Statements and Supplementary Data. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the stockholders and the Board of Directors of Carlisle Companies Incorporated Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Carlisle Companies Incorporated (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of income and comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 13, 2026, expressed an unqualified opinion on the Company’s internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Other Intangible Assets, Net – Henry Indefinite-Lived Trade Name — Refer to Notes 1 and 11 to the financial statements Critical Audit Matter Description The Company has a trade name related to ASP Henry Holdings, Inc. (“Henry”) that is an indefinite-lived intangible asset. As of December 31, 2025, the carrying value of the Henry indefinite-lived trade name is $219.0 million. Management estimates the fair value of its indefinite-lived intangible assets annually on its elected assessment date of November 1, 2025, based on the relief from royalty method which is an income approach utilizing the discounted cash flow method. The determination of the fair value requires management to make significant estimates and assumptions related to forecasts of future trade name revenues, royalty rates that would be paid if licensed from a third-party, and discount rates to estimate the net present value of trade name revenues. Changes in these assumptions could have a significant impact on the fair value of the Henry trade name and a significant change in fair value could cause an impairment. 24
Page 25
Table of Contents Given the determination of the fair value of the Henry trade name requires management to make significant estimates and assumptions relating to the forecasts of Henry trade name revenues and the selection of the royalty and discount rates, performing audit procedures to evaluate the reasonableness of such estimates and assumptions required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to the forecasts of future Henry trade name revenues and selection of the royalty and discount rates for the Henry trade name included the following, among others: • We tested the effectiveness of controls over management’s intangible asset impairment evaluation, including those over the determination of the fair value of the Henry trade name, such as controls related to management’s forecasts of Henry trade name revenues and selection of the royalty and discount rates. • We evaluated management’s ability to accurately forecast future Henry trade name revenues by comparing actual Henry trade name revenues to management’s historical forecasts. • We evaluated the reasonableness of management’s forecasts of future Henry trade name revenues by: ◦ Comparing management’s forecasts with: ▪ Historical revenues. ▪ Internal communications to management. ▪ Forecasted information included in industry reports of the Company and selected companies in its peer group. • With the assistance of our fair value specialists, we evaluated the reasonableness of the royalty and discount rates by: ◦ Testing the source information underlying the determination of the royalty and discount rates and the mathematical accuracy of the calculation. ◦ Developing a range of independent estimates and comparing those to the royalty and discount rates selected by management. /s/ DELOITTE & TOUCHE LLP Tempe, Arizona February 13, 2026 We have served as the Company’s auditor since 2017. 25

Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the stockholders and the Board of Directors of Carlisle Companies Incorporated Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Carlisle Companies Incorporated (the “Company”) as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated February 13, 2026, expressed an unqualified opinion on those financial statements. As described in Management’s Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at ThermaFoam Operating LLC, PowerFoam LLC, and ThermaFoam Real Estate LLC (collectively, "ThermaFoam"), selected assets of which were acquired on February 3, 2025 and whose financial statements constitute approximately 1% of total assets and less than 1% of revenues of the consolidated financial statement amounts as of and for the year ended December 31, 2025, and Bonded Logic, Inc. and Phoenix Fibers, LLC (collectively, "Bonded Logic"), selected assets of which were acquired on June 30, 2025 and whose financial statements constitute approximately 1% of total assets and less than 1% of revenues of the consolidated financial statement amounts as of and for the year ended December 31, 2025. Accordingly, our audit did not include the internal control over financial reporting of ThermaFoam and Bonded Logic. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ DELOITTE & TOUCHE LLP Tempe, Arizona February 13, 2026 26

Table of Contents Notes to Consolidated Financial Statements Note 1—Summary of Accounting Policies Nature of Business Carlisle Companies Incorporated ("Carlisle" or the "Company"), is a leading supplier of innovative building envelope products and solutions for more energy-efficient buildings. Through its building products businesses, Carlisle Construction Materials ("CCM") and Carlisle Weatherproofing Technologies ("CWT"), and family of leading brands, Carlisle delivers innovative, labor- reducing and environmentally responsible products and solutions to customers through the Carlisle Experience. Basis of Presentation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All material intercompany transactions and accounts have been eliminated. Certain prior period amounts have been reclassified to conform to the current period's presentation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Foreign Currency Matters The functional currency of the Company’s subsidiaries outside the United States of America ("United States" or "U.S.") is the currency of the primary economic environment in which the subsidiary operates. Assets and liabilities of these operations are translated to the U.S. Dollar at the exchange rate in effect at each balance sheet date. Income statement accounts are translated at the average rate of exchange prevailing during the year. Translation adjustments arising from the use of differing exchange rates from period to period are included as a component of stockholders’ equity in accumulated other comprehensive loss. Gains and losses from foreign currency transactions and from the remeasurement of monetary assets and liabilities and associated income statement activity of foreign subsidiaries where the functional currency is the U.S. Dollar and the records are maintained in the local currency are included in other non-operating expense (income), net. Discontinued Operations The results of operations for the Company's former Carlisle Fluid Technologies ("CFT") and Carlisle Interconnect Technologies ("CIT") businesses have been classified as discontinued operations for all periods presented in the Consolidated Statements of Income. Refer to Note 4 for additional information. Revenue Recognition Revenue is recognized when the Company satisfies performance obligations in contracts with customers. Most of the Company’s contracts with customers have a single performance obligation to transfer distinct goods or services, and substantially all of the Company's revenue is recognized at the point in time when control of the goods transfers to the customer. Control typically transfers when the goods are shipped from the manufacturing facility or delivered to the customer, depending on the terms of the contract. Revenue is measured as the amount of total consideration the Company expects to receive for satisfying its performance obligations. At the time of sale, the Company estimates provisions for variable consideration including discounts, rebates and returns based on an analysis of historical experience and actual sales data. At the end of each reporting period, the Company updates these estimates based on actual and expected changes in customer behavior related to early payment discounts, purchase volume-based rebates and rights of return. These changes in estimates are reflected as adjustments to revenue in the period identified. Sales, value-added, and other taxes collected concurrently with revenue-producing activities are excluded from revenue. 31

Table of Contents For separately priced extended warranties, the Company receives payment at the inception of the contract and establishes a contract liability. Revenue is recognized on a straight-line basis over the life of the contracts as the Company satisfies its performance obligations. The term of these warranties ranges from five to 40 years. The weighted-average life of the contracts as of December 31, 2025, is approximately 20 years. Refer to Note 6 for further information on revenue recognition. Costs to Obtain a Contract Costs to obtain a contract are recognized as expenses as incurred, as the amortization period of these costs would be one year or less. These costs generally include sales commissions and are included in selling and administrative expenses. Shipping and Handling Costs Costs incurred to physically transfer product to customer locations are recorded as a component of cost of goods sold. Charges passed on to customers are included in revenues. Other Non-operating Expense (Income), net Other non-operating expense (income), net primarily includes foreign currency exchange (gains) losses, (gains) losses on pension settlements, (gains) losses on Rabbi Trust investments and (gains) losses on the sale of a business. Stock-Based Compensation The Company accounts for stock-based compensation using the fair-value method. For equity-classified awards, the cost is measured at the grant date based on the fair value of the award and is recognized as compensation cost over the requisite service period. This requisite service period typically matches the award's stated vesting period but may be shorter if the award fully vests upon the employee's retirement or termination from the Company. The Company recognizes compensation cost for awards that have graded vesting features under the graded vesting method, which considers each separate vesting tranche as though they were, in substance, a separate award. The Company also accounts for forfeitures of stock-based awards as they occur. Refer to Note 7 for additional information regarding stock-based compensation. Income Taxes Income taxes include an estimate of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Deferred tax assets and liabilities reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company uses the portfolio approach for releasing income tax effects associated with amounts reclassified out of accumulated other comprehensive loss. Refer to Note 8 for further information regarding income taxes. Cash Equivalents Highly liquid investments with a maturity of three months or less when acquired are considered cash equivalents. Receivables and Allowance for Credit Losses Receivables are stated at amortized cost, net of allowances for credit losses. The Company regularly evaluates the creditworthiness of its customers by reviewing their credit information. This assessment determines if any events have occurred subsequent to revenue recognition that indicate the receivable might be realized at an amount less than that recognized at the time of sale. Credit loss estimates are based on historical losses, current economic conditions, geographic considerations, and in some cases, assessments of specific customer accounts for potential risk of loss. 32

Table of Contents Inventories Inventories are valued at the lower of cost and net realizable value, with cost determined primarily on an average cost basis. Cost of inventories includes raw materials, direct and indirect labor, and manufacturing overhead. Manufacturing overhead includes materials; depreciation and amortization related to property, plant and equipment and other intangible assets used directly and indirectly in the acquisition and production of inventory; and costs related to the Company’s distribution network such as inbound freight charges, purchasing and receiving costs, inspection costs, warehousing costs, internal transfer costs and other costs associated with preparing the Company’s products for sale. Refer to Note 9 for further information regarding inventories. Property, Plant and Equipment Property, plant and equipment are stated at cost including interest costs associated with qualifying capital additions. Costs allocated to property, plant and equipment of acquired companies are based on estimated fair value at the date of acquisition. Depreciation is principally computed on a straight-line basis over the estimated useful lives of the assets. Asset lives are generally 20 to 40 years for buildings, five to 15 years for machinery and equipment and two to 20 years for leasehold improvements. Leasehold improvements are amortized based on the shorter of the underlying lease term or the asset’s estimated useful life. Refer to Note 10 for further information regarding property, plant and equipment. Valuation of Long-Lived Assets Long-lived assets or asset groups, including amortizable intangible assets, are tested for impairment whenever events or circumstances indicate that the carrying amount of the asset or asset group may not be recoverable. The Company groups its long-lived assets classified as held and used at the lowest level for which identifiable cash flows are largely independent of the cash flows from other assets and liabilities for purposes of testing for impairment. The Company’s asset groupings vary based on the related business in which the long-lived assets are employed and the interrelationship between those long-lived assets in producing net cash flows; for example, multiple manufacturing facilities may work in concert with one another or may work on a stand-alone basis to produce net cash flows. The Company utilizes its long-lived assets in multiple industries and economic environments and its asset groupings reflect these various factors. The Company monitors the operating and cash flow results of its long-lived assets or asset groups classified as held and used to identify whether events and circumstances indicate the remaining useful lives of those assets should be adjusted or if the carrying value of those assets or asset groups may not be recoverable. Undiscounted estimated future cash flows are compared with the carrying value of the long-lived asset or asset group in the event indicators of impairment are identified. If the undiscounted estimated future cash flows are less than the carrying amount, the Company determines the fair value of the asset or asset group and records an impairment charge in current earnings to the extent carrying value exceeds fair value. Fair values may be determined based on estimated discounted cash flows by prices for like or similar assets in similar markets or a combination of both. Long-lived assets or asset groups that are part of a disposal group that meets the criteria to be classified as held for sale are not assessed for impairment, but rather a loss is recorded against the disposal group if fair value, less cost to sell, of the disposal group is less than its carrying value. Goodwill and Other Intangible Assets Goodwill is not amortized but is tested for impairment annually, or more often if impairment indicators are present, at a reporting unit level by comparing the fair value of the reporting unit with its carrying value. The Company's annual testing date for goodwill is November 1. The Company determined it had four reporting units within its two reportable segments. 33
Page 34
Table of Contents Intangible assets are recognized and recorded at their acquisition date fair values. Intangible assets that are subject to amortization are amortized on a straight-line basis over their useful lives. Definite-lived intangible assets consist primarily of acquired customer relationships, patents and technology, and certain trade names. The Company determines the useful life of its definite-lived intangible assets based on multiple factors including the size and make-up of the acquired customer base, the expected dissipation of those customers over time, the Company’s own experience in the particular industry, the impact of known trends such as technological obsolescence and product demand and the period over which expected cash flows are used to measure the fair value of the intangible asset at acquisition. The Company periodically re-assesses the useful lives of its definite-lived intangible assets when events or circumstances indicate that useful lives have significantly changed from the previous estimate. Intangible assets with indefinite useful lives are not amortized but are tested for impairment annually, or more often if impairment indicators are present, by comparing the fair value of the intangible asset with its carrying value. The Company's annual testing date for indefinite-lived intangible assets is November 1. The Company periodically re-assesses indefinite-lived intangible assets as to whether their useful lives can be determined and, if so, begins amortizing any applicable intangible asset. Refer to Note 11 for additional information regarding goodwill and other intangible assets. Extended Product Warranty Reserves The Company offers extended warranty contracts on sales of certain products; the most significant being those offered on its installed roofing and weatherproofing systems. Current costs of services performed under these contracts are expensed as incurred and included in cost of goods sold. The Company would record a reserve within accrued expenses if the total expected costs of providing services at a product line level exceed unamortized deferred revenues. Total expected costs of providing extended product warranty services are actuarially determined using standard quantitative measures based on historical claims experience and management judgment. Refer to Note 6 for additional information regarding deferred revenue and extended product warranties. Pension The Company maintains defined benefit pension plans primarily for certain domestic employees. The annual net periodic benefit cost and projected benefit obligations related to these plans are determined on an actuarial basis annually on December 31, unless a remeasurement event occurs in an interim period. This determination requires assumptions to be made concerning general economic conditions (particularly interest rates), expected return on plan assets, increases to compensation levels and mortality rate trends. Changes in the assumptions to reflect actual experience can result in a change in the net periodic benefit cost and projected benefit obligations. The defined benefit pension plans’ assets are measured at fair value annually on December 31, unless a remeasurement event occurs in an interim period. The Company uses the market related valuation method to determine the value of plan assets for purposes of determining the expected return on plan assets component of net periodic benefit cost. The market related valuation method recognizes the change of the fair value of the plan assets over five years. If actual experience differs from these long-term assumptions, the difference is recorded as an actuarial gain (loss) and amortized into earnings over a period of time based on the average future service period, which may cause the expense related to providing these benefits to increase or decrease. Refer to Note 14 for additional information regarding these plans and the associated plan assets. Leases The Company determines if an arrangement is a lease at inception by evaluating if the asset is explicitly or implicitly identified or distinct, if the Company will receive substantially all of the economic benefit, or if the lessor has an economic benefit and the ability to substitute the asset. Right-of-use assets ("ROU assets") represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date of the lease, measured based on the present value of fixed and known lease payments over the lease term, and recorded in other long-term assets, other current liabilities, and other long-term liabilities. Variable payments are not included in the ROU asset or lease liability and can vary from period to period based on the use of an asset during the period or the Company's proportionate share of common costs. As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the 34
Page 35
Table of Contents present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and lease expense for these leases is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease components and non-lease components. The Company has elected to apply the practical expedient to account for these components as a single lease component, for all classes of underlying assets. Refer to Note 15 for additional information regarding leases. Contingencies and Insurance Recoveries The Company is exposed to losses related to various potential claims related to its employee obligations and other matters in the normal course of business, including commercial, employee, environmental or other regulatory claims. The Company records a liability related to such potential claims, both those reported to the Company and incurred but not yet reported, when probable and reasonably estimable. The Company expenses legal defense costs related to such matters as incurred. The Company maintains occurrence-based insurance contracts related to certain contingent losses, primarily workers’ compensation, medical and dental, general liability, property, and product liability claims up to applicable retention limits as part of its risk management strategy. The Company records a recovery under these insurance contracts when such recovery is deemed probable. Insurance proceeds in excess of realized losses are gain contingencies and not recorded until realized. Refer to Note 15 for additional information regarding contingencies and insurance recoveries. Financial Instruments From time to time, the Company may enter into derivative financial instruments to hedge various risks to cash flows or the fair value of recognized assets and liabilities, including those arising from fluctuations in foreign currencies, interest rates and commodities. The Company recognizes these instruments at the time they are entered into and measures them at fair value. For instruments that are designated and qualify as cash flow hedges under GAAP, the changes in fair value period-to- period, less any excluded components, are classified in accumulated other comprehensive loss, until the underlying transaction being hedged impacts earnings. The excluded components are recorded in current period income (loss). For those instruments that are designated and qualify as fair value hedges under GAAP, the changes in fair value period-to-period of both the derivative instrument and underlying hedged item are recognized currently in earnings. For those instruments not designated or those that do not qualify as hedges under GAAP, the changes in fair value period-to-period are classified immediately in current period income, within other non-operating expense (income), net. Other financial instruments include cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and long-term debt. The carrying values for cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair values because of their short-term nature and negligible credit losses. Refer to Note 13 for the fair value of long-term debt. New Accounting Standards Adopted In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023- 09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), which is intended to improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments which are intended to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for the Company beginning January 1, 2025, and the Company applied this standard retrospectively. The adoption of this standard did not require an implementation adjustment and did not impact the Company's consolidated net income or cash flows. Refer to Note 8 for updated disclosures. 35
Page 36
Table of Contents New Accounting Standards Issued But Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses ("ASU 2024-03"), which is intended to improve the disclosures about a public business entity’s expenses and address requests from investors for more detailed information about the types of expenses in commonly presented expense captions (such as cost of sales; selling, general, and administrative expenses; and research and development). ASU 2024-03 will be effective for the Company's fiscal year beginning January 1, 2027 and allows the use of a prospective or retrospective approach. The Company plans to adopt the standard on January 1, 2027, and has not yet determined the potential impact. Note 2—Segment Information The Company has two reportable segments: Carlisle Construction Materials ("CCM")—this segment produces a complete line of premium single-ply roofing products and warranted roof systems and accessories for the commercial building industry, including ethylene propylene diene monomer (“EPDM”), thermoplastic polyolefin (“TPO”) and polyvinyl chloride (“PVC”) membrane, polyiso insulation, and engineered metal roofing and wall panel systems for commercial and residential buildings.

Note 5—Earnings Per Share Restricted stock awards granted as part of the Company's Incentive Compensation Program participate in nonforfeitable dividends on a one-to-one per-share ratio with common stock. As such, unvested restricted stock awards are considered participating securities in the computation of earnings per share under the two-class method, and undistributed earnings are allocated between common stock and participating securities on a one-to-one per-share basis. The numerator in the computation of basic and diluted earnings per share excludes income allocated to these participating securities. The denominator in the computation of diluted earnings per share includes the dilutive effect of stock options and performance share awards granted as part of the Company's Incentive Compensation Program. The dilutive effect of stock options is calculated using the treasury stock method when the average market price of the Company's common shares during the reporting period exceeds the exercise price of the options. Performance shares are contingently issuable, and the dilutive effect is based on the number of shares that would have been awarded had the conditions at the end of the reporting period continued until the end of the performance period.

The Program was originally approved by the Company’s stockholders at the Company's 2024 Annual Meeting of Stockholders. As of December 31, 2025, 2.7 million shares remained available for issuance under the Program, and 0.8 million of those shares were available for grant as restricted shares, performance shares or other “full value” awards. During the year ended December 31, 2025, the Company awarded 108 thousand stock options, 30 thousand restricted stock awards and 20 thousand performance share awards as part of the Program with an aggregate grant-date fair value of approximately $35.4 million to be recognized over the requisite service period for each award. Stock-based compensation cost by award type follows: (in millions) 2025 2024 2023 Stock option awards $ 13.1 $ 14.0 $ 14.4 Restricted stock awards 10.8 9.4 8.3 Performance share awards 10.5 9.4 8.8 Total stock-based compensation cost incurred 34.4 32.8 31.5 Capitalized cost during the period (1.9) (3.3) (4.5) Amortization of capitalized cost during the period 2.3 3.4 4.7 Total stock-based compensation expense $ 34.8 $ 32.9 $ 31.7 Income tax benefit $ 17.8 $ 18.7 $ 11.4 Stock Option Awards Stock options awarded under the Program generally vest on a straight-line basis over a three-year period on the anniversary date of the grant. All stock options have a maximum contractual term of 10 years. Shares issued to cover stock options issued under the Program may be issued from shares held in treasury, from new issuances of shares or a combination of the two. Unrecognized compensation cost from continuing operations related to stock options of $7.5 million as of December 31, 2025, is to be recognized over a weighted-average period of 1.5 years. The Company determines the fair value of its stock options using the Black-Scholes-Merton option pricing model. The weighted average assumptions used in the determination of fair value for stock options follow: 2025 2024 2023 Expected dividend yield 1.0 % 1.2 % 1.2 % Expected term (in years) 4.5 4.7 4.6 Expected volatility 28.7 % 32.1 % 32.4 % Risk-free interest rate 4.2 % 3.9 % 3.6 % The expected dividend yield is based on the latest quarterly dividend payment per share, annualized, divided by the average three-month stock price as of the date of grant. The expected term is based on the assumption that all outstanding stock options will be exercised at the midpoint of the valuation date (if vested) or the vesting dates (if unvested) and the stock options’ expiration date. The expected volatility is based on historical volatility and the implied volatility of the Company’s call options. The risk-free interest rate is based on rates of U.S. Treasury issues with a remaining life equal to the expected term of the stock option. 46

Unrecognized compensation cost from continuing operations related to performance share awards of $10.7 million as of December 31, 2025, is to be recognized over a weighted-average period of 1.7 years. The Company utilizes the Monte-Carlo simulation approach based on a three-year measurement period to determine the fair value of performance shares. Such approach entails the use of assumptions regarding the future performance of the Company’s stock and those of the S&P Midcap 400 Index . Those assumptions include expected volatility, risk-free interest rates, correlation coefficients and dividend reinvestment. Dividends accrue on the performance shares during the performance period and are to be paid in cash based upon the number of awards ultimately earned. ® 47

Table of Contents Valuation Allowances As of December 31, 2025, the Company had a deferred tax asset related to federal capital loss carryforwards of $37.6 million, which expire in 2029. The Company believes it is likely the carryforwards will expire unused and therefore has established a full valuation allowance. As of December 31, 2025, the Company had foreign tax credit carryforwards for U.S. federal tax purposes of $2.1 million, which begin to expire in 2030. The Company believes it is likely the credits will expire unused and therefore has established a full valuation allowance. As of December 31, 2025, the Company also had a deferred tax asset for state tax attributes of approximately $22.2 million, which begin to expire in 2026, comprised primarily of capital loss carryforwards, in addition to net operating losses (“NOL”) and credits. The Company believes that it is likely that the capital losses and certain of the state NOLs will expire unused and therefore has established a valuation allowance of approximately $11.4 million against the deferred tax assets associated with these attributes. The Company also has deferred tax assets related to carryforwards in foreign jurisdictions of approximately $18.3 million, comprised of NOL and interest expense carryforwards, which begin to expire in 2026. The Company believes that it is likely that certain foreign NOL carryforwards will expire unused and therefore has established a valuation allowance of approximately $0.9 million. Undistributed Foreign Earnings The Company has determined that an amount attributable to certain foreign cash balances and other certain assets is not permanently reinvested for withholding tax purposes, which results in an accrual of $6.7 million. It is not practicable to calculate deferred tax balances on other basis differences. Unrecognized Tax Benefits Unrecognized tax benefits reflect the difference between the tax benefits of positions taken or expected to be taken on income tax returns and the tax benefits that meet the criteria for current recognition in the financial statements. The Company periodically assesses its unrecognized tax benefits. A summary of the movement in gross unrecognized tax benefits (before estimated interest and penalties) follows: (in millions) 2025 2024 2023 Balance as of January 1 $ 9.6 $ 7.3 $ 6.4 Additions based on tax positions related to current year 3.6 3.1 3.3 Reductions due to statute of limitations (0.8) (0.8) (2.7) Reductions due to settlements — — (0.2) Adjustments due to foreign exchange rates (0.3) — 0.5 Balance as of December 31 $ 12.1 $ 9.6 $ 7.3 If the unrecognized tax benefits as of December 31, 2025 were to be recognized, approximately $10.7 million would impact the Company’s effective tax rate. The amount impacting the Company’s effective rate is calculated by adding accrued interest and penalties to the gross unrecognized tax benefit excluding positions related to discontinued operations and subtracting the federal tax benefit associated with state taxes and interest. The Company classifies and reports interest and penalties associated with unrecognized tax benefits as a component of the income tax provision on the Consolidated Statements of Income and as an other long-term liability on the Consolidated Balance Sheets. The total amount of such interest and penalties accrued, but excluded from the table above, at the years ending December 31, 2025, 2024 and 2023 were $1.4 million, $1.2 million and $1.2 million, respectively. The Company is subject to U.S. federal income tax as well as income tax in multiple state and foreign jurisdictions. The Company participates in the IRS compliance assurance program and is currently up to date. Generally, state income tax returns are subject to examination for a period of three years to five years after filing. Substantially all material state tax matters have been concluded for tax years through 2019. Various state income tax returns for subsequent years are in the process of examination. At this stage the outcome is uncertain; however, the Company believes that contingencies have been adequately provided for. Statutes of limitation vary among the foreign jurisdictions in which the Company operates. Substantially all foreign tax matters have been concluded for tax years through 2014. The Company believes that foreign tax contingencies associated with income tax examinations underway or open tax years have been provided for adequately. 50

Table of Contents Tax Legislation The Organization for Economic Co-operation and Development (“OECD”) has introduced a framework to implement a global minimum corporate tax of 15%, referred to as Pillar Two. Certain countries in which the Company operates have adopted legislation. On January 5, 2026, the OECD released the Side-by-Side addition to the framework, recognizing the US as a qualified regime and limiting the application of Pillar Two taxes to US headquartered multinationals, such as Carlisle, starting in 2026.

The Notes are subject to the restrictive covenants and limitations contained in the Company's indenture dated January 15, 1997, as amended. The Notes are general unsecured obligations of the Company and rank equally with the Company's existing and future unsecured and unsubordinated indebtedness. The Notes are subordinate to any existing or future debt or other liabilities of the Company's subsidiaries. Revolving Credit Facility The Company and Carlisle, LLC, as co-borrowers, are parties to a Fifth Amended and Restated Credit Agreement (the "Credit Agreement") that provides for a $1.0 billion unsecured revolving line of credit with a maturity date of April 3, 2029. Borrowings under the Credit Agreement bear interest, at the Company's election, (i) at the Base Rate plus a margin ranging from —% to 0.50% or (ii) at the applicable benchmark rate plus a margin ranging from 0.825% to 1.500%, in each case, based on the Company’s debt rating from time to time. The benchmark rate for loans denominated in (i) U.S. dollars is the Adjusted Term SOFR Rate, (ii) Canadian dollars is the Adjusted Term CORRA Rate, (iii) Sterling is Daily Simple SONIA, (iv) euros is the Adjusted EURIBOR Rate and (v) yen is Adjusted TIBOR Rate. The commitments are also subject to a facility fee on the daily aggregate amount of the revolving commitment (whether used or unused) ranging from 0.05% to 0.25% based on the Company’s debt rating from time to time. Funding of the loans under the Credit Agreement is subject to customary drawdown conditions. The Company incurred $1.9 million of financing costs in 2024 in connection with finalizing the Credit Agreement, which together with any existing unamortized costs, will be recognized ratably over the extended maturity date of the Credit Agreement. The Credit Agreement has a feature that allows the Company to increase availability, at its option, by an aggregate amount of up to $500.0 million through increased commitments from existing lenders or the addition of new lenders. The Company may also enter into commitments in the form of standby, commercial, or direct pay letters of credit for an amount not to exceed $50.0 million. As of December 31, 2025, the Company had no outstanding balance and $1.0 billion available under the Credit Agreement. During 2025, there were no borrowings and repayments under the Credit Agreement. During 2024, the Company had $22.0 million in borrowings and repayments under the Credit Agreement with a weighted average interest rate of 8.50%. 54

Table of Contents Covenants and Limitations The Notes and the Credit Agreement require the Company to meet various restrictive covenants and limitations, including certain leverage and interest coverage ratios and limits on outstanding debt balances held by certain subsidiaries. The Company was in compliance with all covenants and limitations as of December 31, 2025, and 2024. Letters of Credit and Guarantees During the normal course of business, the Company enters into commitments in the form of letters of credit and bank guarantees to provide its own financial and performance assurance to third parties. The Company has not issued any guarantees on behalf of any third parties. As of December 31, 2025, and 2024, the Company had $48.8 million and $22.8 million, respectively, in letters of credit and bank guarantees outstanding. The Company has multiple arrangements for up to $100.0 million in letters of credit, of which $51.2 million was available as of December 31, 2025. Interest Payments Cash payments for interest were $56.2 million, $70.2 million and $71.9 million in 2025, 2024, and 2023, respectively. Note 14—Employee Benefit Plans Defined Benefit Plans The Company maintains defined benefit retirement plans, primarily for certain domestic employees, as presented below. All plans are frozen to new entrants, with the exception of the executive supplemental plan. Benefits are based primarily on years of service and earnings of the employee. The significant assumptions used in the measurement of the projected benefit obligation and net periodic benefit cost primarily include the discount rate, rate of compensation increase and expected long-term return on plan assets. Weighted- average assumptions for the projected benefit obligation follow: December 31,2025 December 31,2024 Discount rate 5.2 % 5.5 % Rate of compensation increase 3.8 % 3.8 % Weighted-average assumptions for net periodic benefit cost follow: 2025 2024 2023 Discount rate 5.5 % 4.8 % 5.1 % Rate of compensation increase 3.8 % 3.8 % 3.8 % Expected long-term return on plan assets 6.7 % 6.0 % 6.0 % The weighted-average cash balance interest crediting rate for the Company's cash balance defined benefit plans was 4.0% for the years ended December 31, 2025, 2024, and 2023. The Company considers several factors in determining the long-term rate of return for plan assets. Asset-class return expectations are set using a combination of empirical and forward-looking analyses. Capital market assumptions for the composition of the Company’s asset portfolio are intended to capture the behavior of asset classes observed over several market cycles. The Company also looks to historical returns for reasonableness and appropriateness. 55

Table of Contents The Company employs a liability driven investment approach whereby plan assets are invested primarily in fixed income investments to match the changes in the projected benefit obligation of funded plans related to changes in interest rates. Risk tolerance is established through careful consideration of projected benefit obligations, plan funded status and the Company’s other obligations and strategic investments. The established target allocation is 88.0% fixed income securities and 12.0% equity securities. Fixed income investments are diversified across U.S. treasury, long and intermediate duration and high yield bonds. Equity investments are diversified across large capitalization U.S. and international stocks. Investment risk is measured and monitored on an ongoing basis through investment portfolio reviews, annual projected benefit liability measurements and asset/liability studies. The fair value measurement of the plans’ assets by asset category follows: Quoted Prices in Active Marketsfor Identical Assets (Level 1) (in millions) December 31,2025 December 31,2024 Cash $ 3.5 $ 4.7 U.S. treasury bonds 6.7 6.4 Mutual funds: Equity mutual funds 6.7 5.6 Fixed income mutual funds 37.8 41.5 Total $ 54.7 $ 58.2 This category is comprised of investments in mutual funds that invest in equity securities such as large publicly traded companies listed in the S&P 500 Index; small to medium sized companies with market capitalization in the range of the Russell 2500 Index; and foreign issuers in emerging markets. This category is comprised of investments in mutual funds that invest in U.S. corporate fixed income securities, including asset-backed securities; high yield fixed income securities primarily rated BB, B, CCC, CC, C and D; and US dollar denominated debt securities of government, government related and corporate issuers in emerging market countries. The Company made contributions of $1.5 million and $2.1 million during 2025 and 2024, respectively. Contributions of $1.5 million and $1.6 million in 2025 and 2024, respectively, pertain to the Company’s executive supplemental and director defined benefit pension plans. This contribution covers current participant benefits as these plans have no plan assets. No minimum contributions to the pension plans were required in 2025 and 2024. During 2026, the Company expects to pay approximately $1.3 million in participant benefits under the executive supplemental and director plans. A summary of estimated future benefits to be paid for the Company’s defined benefit pension plans as of December 31, 2025, follows: (in millions) 2026 2027 2028 2029 2030 2031-2035 Estimated benefit payments $ 9.5 $ 7.0 $ 6.6 $ 6.5 $ 5.9 $ 29.7 Pension Settlement The Company recognizes a pension settlement gain or loss when the cost of all settlements in a year is greater than the sum of the service cost and interest cost components of net periodic benefit cost. Total settlements for the year ended December 31, 2025, exceeded the sum of service and interest costs, which resulted in the Company recognizing a non-cash pre-tax pension settlement charge of $3.0 million for the year. On October 17, 2024, the Company entered into an agreement with an insurance company to purchase a nonparticipating single premium group annuity contract. In selecting the insurance company, the Company utilized guidance from the U.S. Department of Labor Interpretive Bulletin 95-1. Using plan assets, the Company transferred $55.0 million of certain defined benefit pension obligations to the insurance company. The contract covers approximately 1,300 Carlisle plan participants and beneficiaries (the "Transferred Participants"). Under this contract, the insurance company made an unconditional and irrevocable commitment to pay the pension benefits of each Transferred Participant that are due on or after January 1, 2025. The transaction did not change the amount of benefits payable to the Transferred Participants. (1) (2) (1) (2) 57
Page 58
Table of Contents As a result of the transaction, the Company recognized non-cash pre-tax pension settlement charges of $21.1 million in the fourth quarter of 2024 related to the accelerated recognition of actuarial losses included within accumulated other comprehensive loss. The transaction also required the Company to remeasure the benefit obligations and plan assets as of the settlement date. The remeasurement reflected the use of an updated discount rate as of the remeasurement date of 5.0%, as compared to the discount rate of 4.8% that was used to determine benefit obligations as of December 31, 2023. Defined Contribution Plans 401K Plan The Company maintains defined contribution savings plans covering a significant portion of its eligible employees. Participant contributions are matched by the Company up to a 4.0% maximum of eligible compensation, subject to compensation and contribution limits as defined by the Internal Revenue Service. Employer contributions for the savings plan were $17.4 million, $17.5 million, and $19.9 million in 2025, 2024 and 2023, respectively. Note 15—Commitments and Contingencies Leases Lease Costs, Assets and Liabilities The Company has operating leases primarily for manufacturing facilities, warehouses, offices and certain equipment.

Table of Contents Litigation Over the years, the Company has been named as a defendant, along with numerous other defendants, in lawsuits in various courts in which plaintiffs have alleged injury due to exposure to asbestos-containing friction products produced and sold predominantly by the Company’s discontinued Motion Control business between the late-1940s and the mid-1980s and roofing products produced and sold by Henry Company LLC, which the Company acquired on September 1, 2021. The Company has been subject to liabilities for indemnity and defense costs associated with these lawsuits. The Company has recorded a liability for estimated indemnity costs associated with pending and future asbestos claims. As of December 31, 2025, the Company believes that its accrual for these costs is not material to the Company's financial position, results of operations or operating cash flows. The Company recognizes expenses for defense costs associated with asbestos claims during the periods in which they are incurred. Refer to Note 1 for the Company’s accounting policy related to litigation defense costs. The Company currently maintains insurance coverage and is the beneficiary of other arrangements that provide coverage with respect to asbestos-related claims and associated defense costs. The Company records the insurance coverage as a receivable in an amount it reasonably estimates is probable of recovery for pending and future asbestos-related indemnity claims. Since the Company’s insurance coverage contains various exclusions, limits of coverage and self-insured retentions and may be subject to insurance coverage disputes, the Company may incur expenses for indemnity and defense costs and recognize income from insurance recoveries in different periods. As such, recoveries are recorded only if and when it becomes probable that such costs will be covered by insurance. The Company is also involved in various other legal actions and proceedings arising in the ordinary course of business. In the opinion of management, the ultimate outcomes of such actions and proceedings, either individually or in the aggregate, are not expected to have a material adverse effect on the Company’s financial position, results of operations, or operating cash flows. 59

(a) Evaluation of disclosure controls and procedures. Under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, the Company carried out an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-15. Based upon that evaluation and as of December 31, 2025, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective. Management has prepared a report on the Company’s internal control over financial reporting in which management has determined that the Company’s controls are effective. A copy of management’s report is set forth below. (b) Changes in internal controls. During the fourth quarter of 2025, there were no changes in the Company's internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting. Management’s Report on Internal Control over Financial Reporting The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, the Company evaluated the effectiveness of the design and operation of its internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s internal control over financial reporting was effective as of December 31, 2025. As discussed in Note 3 to the Consolidated Financial Statements in Item 8, the Company completed the acquisition of selected assets of ThermaFoam Operating LLC, PowerFoam LLC, and ThermaFoam Real Estate LLC (collectively, "ThermaFoam") on February 3, 2025, and selected assets of Bonded Logic, Inc. and Phoenix Fibers, LLC (collectively, "Bonded Logic") on June 30, 2025. Management's assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of ThermaFoam or Bonded Logic, which each represented approximately 1% of total assets as of December 31, 2025, and each represented less than 1% of revenues for the year then ended. The Company's internal control over financial reporting has been audited by Deloitte & Touche LLP, whose report with respect to the effectiveness of internal control over financial reporting is included in Item 8.

Exhibit 4.1 DESCRIPTION OF CARLISLE COMPANIES INCORPORATED’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934 Carlisle Companies Incorporated, a Delaware corporation (“we,” “our” the “Company”), has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended: our common stock. The following is a summary description of our common stock and does not purport to be complete. For a complete description of the terms and provisions of our common stock refer to our Amended and Restated Certificate of Incorporation (our “Certificate of Incorporation”) and Amended and Restated Bylaws (our “Bylaws”). This summary description is qualified in its entirety by reference to these documents, each of which is included as an exhibit to the Annual Report on Form 10-K to which this exhibit is a part. Authorized Capital Stock Pursuant to our Certificate of Incorporation, our authorized capital stock consists of (i) 200,000,000 shares of common stock, $1.00 par value per share, and (ii) 5,000,000 shares of preferred stock, $1.00 par value per share. Common Stock Voting Rights Common stockholders are entitled to one vote per share. Our Certificate of Incorporation and our Bylaws do not provide for cumulative voting rights. Dividends Subject to the rights of the holders of any outstanding shares of preferred stock, holders of our shares of common stock are entitled to receive such dividends as may be declared from time to time by our board of directors from our assets legally available for the payment of dividends. Liquidation, Redemption and Preemptive Rights In the event of our voluntary or involuntary liquidation, dissolution or winding up, after the payment or provision for payment of our debts and other liabilities and the preferential amounts to which holders of our preferred stock are entitled (if any shares of preferred stock are then outstanding), the holders of our common stock are entitled to share ratably in our remaining assets.

Transfer Agent and Registrar The transfer agent and registrar is Computershare Investors Services, LLC. Anti-Takeover Provisions of Our Certificate of Incorporation and our Bylaws Classification of Board of Directors Our board of directors is divided into three approximately equal classes, having staggered terms of office of three years each. The effect of a classified board of directors may be to make it more difficult to acquire control of us. Removal of Directors Our Certificate of Incorporation also provides that our directors may be removed only for cause and upon the affirmative vote of the holders of at least 66⅔% of the shares then entitled to vote at an election of directors, provided that if there is a substantial stockholder (as defined below), the 66⅔% vote must include the affirmative vote of at least 50% of the voting power of the outstanding shares of our voting capital stock held by stockholders other than the substantial stockholder. Director Nominations Our stockholders can nominate candidates for the board of directors if the stockholders follow the advance notice procedures described in our Certificate of Incorporation. To nominate directors, stockholders must submit a written notice to our Corporate Secretary at least 90 days prior to the first anniversary of the last meeting of stockholders of the Company called for the election of directors, before a scheduled meeting. The notice must include the name and address of the shareholder and of the shareholder's nominee, the number of shares held by the shareholder as a beneficial owner (as defined in our Certificate of Incorporation), and any other information required by the securities laws and the Securities Exchange Commission about the shareholder’s nominee. Stockholders’ Action Our Certificate of Incorporation provides that no shareholder action may be taken by written consent of stockholders. Stockholders Special Meetings A special meeting of stockholders will be called upon the request of the holders of at least 66⅔% of the voting stock of the Company. 2

Supermajority Vote in Business Combinations Article Seventh of our Certificate of Incorporation provides that a merger, consolidation, sale of assets, sale of shares, share exchange, recapitalization, reorganization or other similar transaction (each defined as a “business combination”) between us or a company controlled by or under common control with us and any individual, corporation or other entity which is defined in our Certificate of Incorporation as a “substantial stockholder” (in general, any individual or entity which owns or controls at least 15% of our voting capital stock), would be required to satisfy the condition that the aggregate consideration per share to be received in the transaction for each class of our voting capital stock meet the price requirements indicated in our Certificate of Incorporation. If a proposed business combination with a substantial stockholder does not meet this condition, then the transaction must be approved by the holders of at least 66⅔% of the outstanding shares of voting capital stock held by our stockholders other than the substantial stockholder, unless: (i) a majority of the directors have expressly approved the business combination at a time when the substantial stockholder was not beneficial owner of 5% or more of the outstanding voting shares of the Company or (ii) the business combination is approved by a majority of the directors who are not affiliated with the substantial shareholder. The provisions of Article Seventh may not be amended, altered, changed or repealed except by the affirmative vote of at least 66⅔% of the votes entitled to be cast thereon at a meeting of our stockholders duly called for consideration of such amendment, alteration, change or repeal. In addition, if there is a substantial stockholder, the 66⅔% majority required to amend or repeal Article Seventh must include the affirmative vote of at least 50% of the shares held by stockholders other than the substantial stockholder. Preferred Stock Purchase Rights All rights under the preferred stock purchase rights expired on May 25, 2016. 3
