The ITW Business Model

The powerful and highly differentiated ITW Business Model is the Company's core source of value creation. It is the Company's competitive advantage and defines how ITW creates value for its shareholders. The ITW Business Model is comprised of three unique elements:

• ITW's 80/20 Front-to-Back process is the operating system that is applied in every ITW business. Initially introduced as a manufacturing efficiency tool in the 1980s, ITW has continually refined, improved and expanded 80/20 into a proprietary, holistic business management process that generates significant value for the Company and its customers. Through the application of data driven insights generated by 80/20 practice, ITW focuses on its largest and best opportunities (the "80") and eliminates cost, complexity and distractions associated with the less profitable opportunities (the "20"). 80/20 enables ITW businesses to consistently achieve world-class operational excellence in product availability, quality, and innovation, while generating superior financial performance;

• Customer-back Innovation** has fueled decades of profitable growth at ITW. The Company's unique innovation approach is built on insight gathered from the 80/20 Front-to-Back process. Working from the customer back, ITW businesses position themselves as the go-to problem solver for their "80" customers. ITW's innovation efforts are focused on understanding customer needs, particularly those in "80" markets with solid long-term growth fundamentals, and creating unique solutions to address those needs. These customer insights and learnings drive innovation at ITW and have contributed to a portfolio of approximately 19,600 granted and pending patents;

• ITW's Decentralized, Entrepreneurial Culture enables ITW businesses to be fast, focused, and responsive. ITW businesses have significant flexibility within the framework of the ITW Business Model to customize their approach in order to best serve their specific customers' needs. ITW colleagues recognize their unique responsibilities to execute the Company's strategy and values. As a result, the Company maintains a focused and simple organizational structure that, combined with outstanding execution, delivers best-in-class services and solutions adapted to each business' customers and end markets.

ENTERPRISE STRATEGY: 2012 - 2023

In late 2012, ITW began its strategic framework transitioning the Company to fully leverage the unique and powerful set of capabilities and operating practices of the ITW Business Model. The Company undertook a complete review of its performance, focusing on its businesses delivering consistent above-market growth with best-in-class margins and returns, and developing a strategy to replicate that performance across its operations. ITW determined that solid and consistent above-market organic growth is the core growth engine to deliver world-class financial performance and compelling long-term returns for its shareholders.

Key initiatives in the Company's enterprise strategy included portfolio management, business structure simplification, strategic sourcing and the diligent re-application of ITW's proprietary 80/20 Front-to-Back process.

• As part of the Portfolio Management initiative, ITW exited businesses that were operating in commoditized market spaces and prioritized sustainable differentiation as a must-have requirement for all ITW businesses. This process included both divesting entire businesses and exiting commoditized product lines and customers inside otherwise highly differentiated ITW divisions.

• Business Structure Simplification was implemented to simplify and scale up ITW's operating structure to support increased engineering, marketing, and sales resources, and improve global reach and competitiveness, all of which were critical to driving accelerated organic growth. ITW now has 84 scaled-up divisions with significantly enhanced focus on growth investments, core customers and products, and customer-back innovation.

• The Strategic Sourcing initiative established sourcing as a core strategic and operational capability at ITW, delivering an average of one percent reduction in spend each year since 2013 and continues to be a key contributor to the Company's ongoing enterprise strategy.

• With the initial portfolio realignment and scale-up work largely completed, the Company shifted its focus to preparing for and accelerating organic growth, reapplying the 80/20 Front-to-Back process to optimize its scaled-up divisions for growth, first, to build a foundation of operational excellence, and second, to identify the best opportunities to drive organic growth.

Since implementing the Company's enterprise strategy in 2012, the Company has demonstrated the compelling performance potential of the ITW Business Model and superior 80/20 management, resulting in meaningful incremental improvement in margins and returns as evidenced by the Company's operating margin and after-tax return on invested capital. At the same time, these 80/20 initiatives can also result in restructuring initiatives that reduce costs and improve profitability and returns.

OUR NEXT PHASE: 2024-2030

In the Next Phase of the Company’s evolution, the ITW Business Model and the Enterprise Strategy framework will be as formidable of a competitive advantage and performance differentiator as it has been over the last decade, if not more so. Volatility, risk and the pace of change in the global operating environment will continue to increase, and a decentralized entrepreneurial culture allows the Company to be a fast adaptor – to read, react, respond and evolve. The Company’s ability to consistently execute and invest through the ups and downs of the business cycle is now a defining competitive advantage.

Throughout the Next Phase, the Company's focus is to build organic growth into a core ITW strength on par with the Company’s world-class financial performance and operational capabilities. Throughout this phase, the Company will sustain its foundational strengths built over the past decade, including the high-quality ITW Business Model practice. Customer-back Innovation (CBI) is the most impactful driver to achieve high-quality organic growth through the cycle by establishing trusted problem solver relationships with key customers to effectively invent solutions that address customers' most critical pain points or tackle the biggest growth opportunities. CBI successes, coupled with underlying market growth and share gains, are how the Company intends to achieve its high-quality organic growth.

Portfolio Discipline

The Company only operates in industries where it can generate significant, long-term competitive advantage from the ITW Business Model. ITW businesses have the right "raw material" in terms of market and business attributes that best fit the ITW Business Model and have significant potential to drive above-market organic growth over the long-term.

The Company focuses on high-quality businesses, ensuring it operates in markets with positive long-term macro fundamentals and with customers that have critical needs and value ITW's differentiated products, services and solutions. ITW's portfolio operates in highly diverse end markets and geographies which makes the Company more resilient in the face of uncertain or volatile market environments.

The Company routinely evaluates its portfolio to ensure it delivers sustainable differentiation and drives consistent long-term performance. This includes both implementing portfolio refinements and assessing selective high-quality acquisitions to supplement ITW's long-term growth potential.

The Company previously communicated its intent to explore options, including potential divestitures, for certain businesses with annual revenues totaling up to $1.0 billion. In the fourth quarter of 2019, the Company completed the divestitures of three businesses. Due to the COVID-19 pandemic, the Company chose to defer any significant divestiture activity in 2020 and 2021. The Company reinitiated the divestiture process in 2022 for certain businesses with combined annual revenues of approximately $0.5 billion, subject to approval by the Company's Board of Directors. In the second quarter of 2022, plans were approved to divest two businesses, including one business in the Polymers & Fluids segment and one business in the Food Equipment segment. In the fourth quarter of 2022, both of these businesses were divested. The business in the Polymers & Fluids segment was sold for $220 million, subject to certain closing adjustments, resulting in a pre-tax gain of $156 million. The business in the Food Equipment segment was sold for $59 million, subject to certain closing adjustments, resulting in a pre-tax gain of $41 million. Operating revenue related to these divested businesses that was included in the Company's results of operations for the twelve months ended December 31, 2022 and 2021 was $106 million and $115 million, respectively.

In the fourth quarter of 2022, plans were approved to divest one business in the Specialty Products segment. This business was presented as held for sale in the Statement of Financial Position as of December 31, 2022 and had assets and liabilities held for sale of $8 million and $1 million, respectively. This business was sold on April 3, 2023, with no significant gain or loss upon sale. Operating revenue related to this business that was included in the Company's results of operations was $9 million, $37 million and $35 million for the twelve months ended December 31, 2023, 2022 and 2021, respectively. Refer to Note 4. Divestitures in Item 8. Financial Statements and Supplementary Data for further information regarding the Company's divestitures.

As the Company continues to make progress toward its full potential, the Company will explore opportunities to reinforce or further expand the long-term organic growth potential of ITW through the addition of selective high-quality acquisitions, such as the acquisition of the Test & Simulation business of MTS Systems Corporation ("MTS") from Amphenol Corporation on December 1, 2021. The operating results of the MTS Test & Simulation business were reported within the Company's Test & Measurement and Electronics segment. Refer to Note 3. Acquisitions in Item 8. Financial Statements and Supplementary Data for further information regarding this acquisition.

80/20 Front-to-Back Practice Excellence

ITW will continue to drive 80/20 Front-to-Back practice excellence in every division in the Company, every day. Driving strong operational excellence in the quality of 80/20 Front-to-Back practice across the Company, division by division, will produce further customer-facing performance improvement in a number of divisions and additional structural margin expansion at the enterprise level.

Current Year Developments

Refer to Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Distribution Methods

The Company's businesses primarily distribute their products directly to industrial manufacturers and through independent distributors.

Backlog

Backlog generally is not considered a significant factor in the Company's businesses as relatively short delivery periods and rapid inventory turnover are characteristic of most of their products.

Competition

With operations in 51 countries, the Company offers a wide range of products in a myriad of markets, many of which are fragmented, and the Company encounters a variety of competitors that vary by product line, end market and geographic area. The Company's competitors include many regional or specialized companies, as well as large U.S. and non-U.S. companies or divisions of large companies. Each of the Company's segments generally has several main competitors and numerous smaller ones in most of their end markets and geographic areas. In addition to numerous smaller regional competitors, the Welding segment competes globally with Lincoln Electric Holdings, Inc. and ESAB Corporation.

In virtually all segments, the Company differentiates its businesses from its competitors based on product innovation, product quality, brand preference and service delivery. Technical capability is also a competitive factor in most segments. The Company believes that each segment's primary competitive advantages derive from the ITW Business Model and decentralized operating structure, which creates a strong focus on end markets and customers at the local level, enabling its businesses to respond rapidly to market dynamics. This structure enables the Company's businesses to drive operational excellence utilizing the Company's 80/20 Front-to-Back process and leveraging its product innovation capabilities. The Company also believes that its global footprint is a competitive advantage in many of its markets, especially in its Automotive OEM segment.

Raw Materials

The Company uses raw materials of various types, primarily steel, resins and chemicals, that are available from numerous commercial sources. The availability of materials and energy has not resulted in any significant business interruptions or other major problems, and no such problems are currently anticipated.

Intellectual Property

The Company owns approximately 4,000 unexpired U.S. patents and 9,900 foreign patents covering articles, methods and machines. In addition, the Company has approximately 1,400 applications for patents pending in the U.S. Patent Office and 4,300 applications pending in foreign patent offices. There is no assurance that any of these patents will be issued. The Company maintains a patent group for the administration of patents and processing of patent applications.

The Company believes that many of its patents are valuable and important; however, the expiration of any one of the Company's patents would not have a material effect on the Company's results of operations or financial position. The Company also credits its success in the markets it serves to engineering capability; manufacturing techniques; skills and efficiency; marketing and sales promotion; and service and delivery of quality products to its customers.

In addition to patents, many of the Company's products and services are sold under various owned or licensed trademarks, which are important to the Company in the aggregate. Some of the Company's more significant trademarks include ITW, which is also used in conjunction with the trademarks of many of the Company's businesses; Deltar and Shakeproof in the Automotive OEM segment; Hobart in the Food Equipment segment; Instron and MTS in the Test & Measurement and Electronics segment; Miller in the Welding segment; Rain-X and Permatex in the Polymers & Fluids segment; Paslode in the Construction Products segment; and Hi-Cone in the Specialty Products segment.

Government Regulations

The Company believes that its businesses and operations, including its manufacturing plants and equipment, are in substantial compliance with all applicable government laws and regulations, including those related to environmental, consumer protection, international trade, labor and employment, human rights, tax, anti-bribery and competition matters. Any additional

measures to maintain compliance are not expected to materially affect the Company's capital expenditures (including expenditures for environmental control facilities), competitive position, financial position or results of operations.

Various legislative and administrative regulations applicable to the Company in the matters noted above have become effective or are under consideration in many parts of the world. To date, such developments have not had a substantial adverse impact on the Company's revenues, earnings or cash flows. However, if new or amended laws or regulations impose significant operational restrictions and compliance requirements upon the Company or its products, the Company's business, capital expenditures, results of operations, financial condition and competitive position could be negatively impacted. Refer to Item 1A. Risk Factors for further information.

Human Capital Management

As of December 31, 2023, the Company employed approximately 45,000 people, with approximately 17,000 people located in the United States and the remainder in multiple other countries where the Company's businesses operate. The Company strives to be a great employer through its demonstrated commitment to employee safety, its workplace culture, talent development, diversity and inclusion, compensation and benefits.

Employee Safety. The safety and well-being of ITW's colleagues around the world is its top priority, in addition to being an essential component of our commitment to be a great employer. Guided by the Company's Enterprise Safety Strategy and the philosophy that every accident is preventable, ITW strives every day to foster a proactive safety culture. ITW's Enterprise Safety Strategy and Safety Policy are based on the following core principles: (i) a goal of zero accidents; (ii) shared ownership for safety (business and individual); (iii) proactive approach focused on accident prevention; (iv) continuous improvement philosophy; and (v) compliance with applicable national, regional, and local health and safety laws and regulations.

Workplace Culture. The Company's culture is deeply rooted in its core values: Integrity, Respect, Trust, Shared Risk and Simplicity. ITW colleagues are empowered to think and act like business owners within the Company's decentralized, entrepreneurial culture. Our decentralized structure allows each division to operate with autonomy and enables our people to embrace the personal impact they can make.

Talent Development. The Company strives for all colleagues to "own" their careers and feel valued for the work they do. ITW colleagues are encouraged to learn new skills and capabilities primarily through on-the-job experience, hands-on coaching and feedback, in addition to formal training.

The Great ITW Leader Framework defines leadership capabilities and attributes to help colleagues to reach their full potential as leaders. Great ITW Leaders are expected to be experts in the practice of the ITW Business Model, make great strategic choices, deliver great results, be great talent managers and provide strong leadership. Great ITW Leaders who have expertise in the ITW Business Model are the critical factor in translating the potential of the ITW Business Model into full performance. Because this expertise develops over time and through specific experiences, the Company focuses on developing and promoting its own talent to support the Company's sustained business success over the long term.

Diversity and Inclusion. ITW believes it is at its best when it brings together unique perspectives, experiences, and ideas. Rooted in ITW's core values of Respect and Integrity, the Company is committed to equal employment opportunity, fair treatment and creating diverse and inclusive workplaces where all ITW colleagues can perform to their full potential. ITW is committed to attracting the best talent and enhancing the diversity of its global leadership teams. ITW drives progress through a comprehensive enterprise Diversity and Inclusion Framework, which focuses on; (i) leadership commitment and accountability; (ii) attracting and retaining global, diverse talent; (iii) creating inclusive workplaces; and (iv) striving to be a great employer.

Compensation and Benefits. As a global employer, the Company is committed to providing market-competitive compensation and benefits that support physical, mental, and financial well-being to attract and retain great talent across its global divisions. Specific compensation and benefits vary worldwide and are based on regional practices. In the U.S., the Company focuses on providing a comprehensive, competitive benefits package that supports the health and wellness, educational endeavors, community involvement and financial stability of its colleagues.

Labor Relations. Less than three percent of the Company's U.S. employees are represented by a labor union. Outside the U.S., employees in certain countries are represented by an employee representative organization, such as a union, works council or employee association. The Company considers its employee relations to be excellent.

Available Information

Copies of the Company's Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934

are available free of charge through the Company's website (www.itw.com), as soon as reasonably practicable after electronically filing with or otherwise furnishing such information to the Securities and Exchange Commission ("the SEC"). The Company's Code of Ethics for the CEO and key financial and accounting personnel is also posted on the Company's website.

The Company's business, financial condition, results of operations and cash flows are subject to various risks, including, but not limited to, those set forth below, which could cause actual results to vary materially from recent results or from anticipated future results. These risk factors should be considered together with information included elsewhere in this Annual Report on Form 10-K. Any of such risks and matters, individually or in combination, could have a material adverse effect on our business, financial condition, results of operations and cash flows, as well as on the attractiveness and value of an investment in the Company’s securities.

Economic Risks

The Company's results are impacted by global economic conditions. Downturns in the markets served by the Company could adversely affect its businesses, results of operations or financial condition.

The Company's businesses are impacted by economic conditions around the globe. Slower economic growth, financial market instability, supply chain disruptions, natural disasters, public health crises (such as the COVID-19 pandemic), labor market challenges, rapid inflation, armed conflicts (such as Russia's ongoing invasion of Ukraine), government deficit reduction, sequestration and other austerity measures impacting the markets the Company serves can adversely affect the Company's businesses by reducing demand for the Company's products and services, limiting financing available to the Company's customers, causing production delays, increasing order cancellations and the difficulty in collecting accounts receivable, increasing price competition, or increasing the risk that counterparties to the Company's contractual arrangements will become insolvent or otherwise unable to fulfill their obligations.

Rising interest rates could have a dampening effect on overall economic activity and/or the financial condition of the Company's customers, either or both of which could negatively affect customer demand for the Company's products and customers' ability to repay obligations to the Company. Rising interest rates could have an impact on the Company and its customers' cost of capital.

The global nature of the Company's operations subjects it to political, economic and social risks that could adversely affect its business, results of operations or financial condition.

Over 50% of the Company's net sales are derived from customers outside the United States, and the Company currently operates in 51 countries. The risks inherent in the Company's global operations include:

• fluctuation in currency exchange rates;

• limitations on ownership or participation in local enterprises;

• price controls, exchange controls and limitations on repatriation of earnings;

• supply chain disruptions, including transportation delays and disruptions;

• political, social and economic instability and disruptions, including political unrest and armed conflicts;

• acts of terrorism;

• the impact of widespread public health crises and pandemics;

• government embargoes, sanctions or foreign trade restrictions;

• the imposition of duties and tariffs and other trade barriers and retaliatory countermeasures;

• government actions impacting international trade agreements, including the EU-UK Trade and Cooperation Agreement;

• import and export controls;

• social and labor unrest and current and changing regulatory environments;

• the potential for expropriation or nationalization of enterprises;

• difficulties in staffing and managing multi-national operations;

• multiple and potentially conflicting laws, regulations and policies that are subject to change;

• limitations on its ability to enforce legal rights and remedies; and

• potentially adverse tax consequences.

The global geopolitical and trade environment has resulted in raw material inflation and potential for increased escalation of domestic and international tariffs and retaliatory trade policies. Further changes in U.S. trade policy (including new or additional increases in duties or tariffs) and retaliatory actions by U.S. trade partners, including sanctions against Russia and developments in U.S.-China trade relations, could result in a worsening of economic conditions. If the Company is unable to successfully manage the risks associated with managing and expanding its international businesses, the Company's business, results of operations or financial condition may be adversely impacted.

A significant fluctuation between the U.S. Dollar and other currencies could adversely impact the Company's operating income.

Although the Company's financial results are reported in U.S. Dollars, a significant portion of its sales and operating costs are realized in other currencies, with the largest concentration of foreign sales occurring in Europe. The Company's profitability is affected by movements of the U.S. Dollar against the Euro and other foreign currencies in which it generates revenues and incurs expenses. Significant long-term fluctuations in relative currency values, and in particular, an increase in the value of the U.S. Dollar against foreign currencies, has had and could have an adverse effect on profitability and financial condition.

Business and Operational Risks

The benefits from the Company's enterprise strategy may not be as expected and the Company's financial results could be adversely impacted, or the Company may not meet its long-term financial performance targets.

As the Company continues to execute on its enterprise strategy initiatives, it remains focused on the core principles of portfolio discipline, 80/20 Front-to-Back practice excellence, and organic growth. Product line and customer base simplification activities, which are core elements of the Company's 80/20 Front-to-Back process, continue to be applied by the Company's operating divisions and are active elements of the enterprise strategy. Although these activities are expected to improve future operating margins and organic revenue growth, they are also expected to have a negative impact on the Company's overall organic revenue growth in the short term. Additionally, other core activities of the enterprise strategy related to portfolio discipline and organic growth, including customer-back innovation, may not have the desired impact on future operating results. If the Company is unable to realize the expected benefits from its enterprise strategy initiatives, the Company's financial results could be adversely impacted, or the Company may not meet its long-term financial performance targets.

The timing and amount of the Company's share repurchases are subject to a number of uncertainties.

Share repurchases constitute a significant component of the Company's capital allocation strategy. The Company has historically funded its share repurchases with free cash flow and short-term borrowings. The amount and timing of share repurchases will be based on a variety of factors. Important factors that could cause the Company to limit, suspend or delay its share repurchases include unfavorable trading market conditions, the price of the Company's common stock, the nature of other investment opportunities presented to the Company from time to time, regulatory developments relating to share repurchase programs, the ability to obtain financing at attractive rates and the availability of U.S. cash.

If the Company is unable to successfully introduce new products, its future growth may be adversely affected.

The Company's ability to develop new products based on innovation can affect its competitive position and sometimes requires the investment of significant time and resources. Difficulties or delays in research, development, production or commercialization of new products and services may reduce future revenues and adversely affect the Company's competitive position. If the Company is unable to create sustainable product differentiation, its organic growth may be adversely affected.

If the Company is unable to adequately protect its intellectual property, its competitive position and results of operations may be adversely impacted.

Protecting the Company's intellectual property is critical to its innovation efforts. The Company owns patents, trade secrets, copyrights, trademarks and/or other intellectual property rights related to many of its products, and also has exclusive and non-exclusive license rights under intellectual property owned by others. The Company's intellectual property rights may be challenged or the Company may be unable to maintain, renew or enter into new license agreements with third-party owners of intellectual property on reasonable terms. Unauthorized use of the Company's intellectual property rights by third parties, particularly in countries where property rights are not highly developed or protected, or inability to preserve existing intellectual property rights could adversely impact the Company's competitive position and results of operations.

The Company has significant goodwill and other intangible assets, and future impairment of these assets could have a material adverse impact on the Company's financial results.

The Company has recorded significant goodwill and other identifiable intangible assets on its balance sheet as a result of acquisitions, including the acquisition of the MTS Test & Simulation business in December 2021. A number of factors may result in impairments to goodwill and other intangible assets, including significant negative industry or economic trends, disruptions to our business, increased competition and significant changes in the use of the assets. Impairment charges could adversely affect the Company's financial condition or results of operations in the periods recognized.

Raw material price increases and supply shortages could adversely affect results.

The supply of raw materials to the Company and to its component parts suppliers could be interrupted for a variety of reasons, including availability and pricing. Prices for raw materials necessary for production have fluctuated significantly in the past and the Company has experienced upward pricing pressure on raw materials such as steel, resins and chemicals. Significant price increases could adversely affect the Company's results of operations and operating margins. In particular, inflation, changes in trade policies, the imposition of duties and tariffs, potential retaliatory countermeasures, public health crises and pandemics (such as the COVID-19 pandemic, which adversely impacted the price and availability of raw materials), threatened or actual military conflicts (such as Russia's ongoing invasion of Ukraine) and severe weather events could adversely impact the price or availability of raw materials. The Company may not be able to pass along increased raw material and components parts prices to its customers in the form of price increases or its ability to do so could be delayed. Consequently, its results of operations and financial condition may be adversely affected.

The Company's defined benefit pension plans are subject to financial market risks that could adversely affect its results of operations and cash flows.

The performance of financial markets and interest rates impact the Company's funding obligations under its defined benefit pension plans. Significant changes in market interest rates, decreases in the fair value of plan assets and investment losses on plan assets may increase the Company's funding obligations and adversely impact its results of operations and cash flows.

If the Company is unable to protect its information technology infrastructure against service interruptions, data corruption, cyber-based attacks or network security breaches, or if there is a violation of data privacy laws, there could be a negative impact on operating results or the Company may suffer financial or reputational damage.

The Company relies on information technology networks and systems, including the Internet, to process, transmit and store electronic information, and to manage or support a variety of business processes and activities, including procurement, manufacturing, distribution, invoicing and collection. These technology networks and systems may be susceptible to damage, disruptions or shutdowns due to failures during the process of upgrading or replacing software, databases or components; power outages; hardware failures; computer viruses; employee error or malfeasance; and attacks by computer hackers, which have continued to increase on a global scale in both magnitude and frequency, taken on novel and unprecedented forms and become more difficult to detect. Minor security breaches have occurred from time to time and are expected to occur in the future. Although the cyber-attacks experienced to date have not had a material impact, future security breaches of our technology networks and systems or those of our vendors and third-party service providers could result in unauthorized disclosure of confidential information or personal data belonging to our employees, partners, customers or suppliers, which could cause reputational and legal harm as we are subject to data privacy laws, including the EU General Data Protection Regulation, in the various countries in which we operate. If our information technology systems suffer severe damage, disruption, or shutdown, and business continuity plans do not effectively resolve the issues in a timely manner, or if we violate data privacy laws, there could be a negative impact on operating results and/or the financial reporting process and the Company may suffer financial or reputational damage.

In addition, cybersecurity laws and regulations continue to evolve, and are increasingly demanding, both in the U.S. and globally, which adds compliance complexity and may increase costs of compliance and expose the Company to reputational damage or litigation, monetary damages, regulatory enforcement actions or fines in one or more jurisdictions.

Strategic Transaction Risks

The Company's acquisition of businesses could negatively impact its profitability and returns.

The Company has engaged in various acquisitions in the past, such as the acquisition of the MTS Test & Simulation business in December 2021, and could choose to acquire additional businesses in the future. Acquisitions involve a number of risks and financial, accounting, managerial and operational challenges, including the following, any of which could adversely affect the Company's profitability and returns:

• The acquired business' inability to adapt to the ITW Business Model or otherwise perform in accordance with the Company's anticipated results or timetable, could cause it to under-perform relative to the Company's expectations and the price paid for it.

• The acquired business could cause the Company's financial results to differ from expectations in any given fiscal period, or over the long term.

• Acquisition-related earnings charges could adversely impact operating results.

• The acquired business could place unanticipated demands on the Company's management, operational resources and financial and internal control systems.

• The Company may assume unknown liabilities, known contingent liabilities that become realized or known liabilities that prove greater than anticipated, internal control deficiencies or exposure to regulatory sanctions resulting from the activities of the acquired business. The realization of any of these liabilities or deficiencies may increase the Company's expenses, adversely affect its financial position or cause noncompliance with its financial reporting obligations.

• As a result of acquisitions, the Company has in the past recorded significant goodwill and other identifiable intangible assets on its balance sheet. If the Company is not able to realize the value of these assets, it may recognize charges relating to the impairment of these assets.

Divestitures pose the risk of retained liabilities that could adversely affect the Company's financial results.

The Company has had significant divestiture activity in the past in accordance with its portfolio management initiative, and it divested one business in the first quarter of 2023 as it continues portfolio refinements to maintain portfolio discipline. The Company has retained certain liabilities directly or through indemnifications made to the buyers against known and unknown contingent liabilities such as lawsuits, tax liabilities, product liability claims and environmental matters, which could adversely affect the Company's financial results.

Tax, Legal and Regulatory Risks

Unfavorable tax law changes and tax authority rulings may adversely affect results.

The Company is subject to income taxes in the U.S. and in various foreign jurisdictions. Domestic and international tax liabilities are based on the income and expenses in various tax jurisdictions. The Company's effective tax rate could be adversely affected by changes in the mix of earnings among countries with differing statutory tax rates, changes in the valuation allowance of deferred tax assets or changes in tax laws. The amount of income taxes is subject to ongoing audits by U.S. federal, state and local tax authorities and by non-U.S. authorities. If these audits result in assessments different from amounts recorded, future financial results may include unfavorable tax adjustments.

Adverse outcomes in legal proceedings or enforcement actions may adversely affect results.

The Company's businesses expose it to potential costs and adverse rulings associated with commercial, intellectual property, employment, toxic tort and other product liability claims and lawsuits. The Company's global operations also subject it to government investigations in numerous countries. We cannot predict the outcome of claims, investigations and lawsuits and we may incur costs, judgments or fines or enter into settlements that could adversely impact our businesses, reputation or future financial results. The Company currently maintains insurance programs consisting of self-insurance up to certain limits and excess insurance coverage for claims over established limits. There can be no assurance that the Company will be able to obtain insurance on acceptable terms or that its insurance programs will provide adequate protection against actual losses. In addition, the Company is subject to the risk that one or more of its insurers may become insolvent and become unable to pay claims that may be made in the future. Even if it maintains adequate insurance programs, claims, judgments or settlements could have a material adverse effect on the Company's financial condition, liquidity and results of operations and on its ability to obtain suitable, adequate or cost-effective insurance in the future.

Uncertainty related to environmental regulation and industry standards, as well as physical risks of climate change, could impact the Company's results of operations and financial position.

Increased public awareness and concern regarding environmental risks, including global climate change, may result in more international, regional and/or federal requirements or industry standards to reduce or mitigate global warming and other environmental risks. These regulations or standards could mandate even more restrictive requirements, such as stricter limits on greenhouse gas emissions and production of single use plastics, than the voluntary commitments that the Company has made or require such changes on a more accelerated time frame. There continues to be a lack of consistent climate legislation, which creates economic and regulatory uncertainty. In addition, the physical risks of climate change may impact the availability and cost of materials and natural resources, sources and supply of energy, product demand and manufacturing and could increase insurance and other operating costs, including, potentially, to repair damage incurred as a result of extreme weather events or to renovate or retrofit facilities to better withstand extreme weather events. If environmental laws or regulations or industry standards are either changed or adopted and impose significant operational restrictions and compliance requirements upon the Company or its products, or the Company's operations are disrupted due to physical impacts of climate change, the Company's business, capital expenditures, results of operations, financial condition and competitive position could be negatively impacted.

The Company may incur fines or penalties, damage to its reputation or other adverse consequences if its employees, agents or business partners violate anti-bribery, competition, export and import, trade sanctions, data privacy, environmental, human rights or other laws.

The Company has a decentralized operating structure under which its individual businesses are allowed significant decision-making autonomy within the Company's strategic framework and internal financial and compliance controls. The Company is subject to complex U.S., foreign and other local laws and regulations that are applicable to its operations, such as anti-bribery and anti-corruption, competition, export and import, trade sanctions, data privacy, environmental and human rights laws. Although the Company has implemented compliance programs which include internal controls, policies and procedures and employee training to deter prohibited practices, these measures may not be effective in preventing employees, agents or business partners from violating or circumventing such internal policies and violating applicable laws and regulations. Any such improper actions could subject the Company to civil or criminal investigations, could lead to substantial civil or criminal monetary and non-monetary penalties against the Company or its subsidiaries, or could damage its reputation.

Risk Management and Strategy

The Company utilizes information systems to support a variety of business processes and activities in its decentralized operations. These systems may be subject to cyber-based attacks or breaches. For additional information related to the risks associated with cybersecurity threats, refer to the Business and Operational Risks section of Item 1A. Risk Factors.

Cybersecurity risk management is part of the Company's global enterprise risk management program. In order to manage the risks associated with cybersecurity threats, the Company has implemented a robust risk-based cybersecurity program consisting of processes, technologies, and controls to assess, identify and manage material risks from cybersecurity threats.

A key part of the Company’s cybersecurity program is the ITW Cybersecurity Framework, which is based on the National Institute of Standards and Technology’s Cybersecurity Framework ("CSF") and is designed to protect the Company’s data through rapid identification of and effective response to cybersecurity incidents. The Company’s framework includes detailed processes and controls related to backup and recovery, response planning, awareness, vulnerability management and endpoint protection as well as cybersecurity requirements for third-party service providers. The framework is regularly reviewed, assessed, and updated based on input from third party specialists, threat intelligence firms and CSF standard updates.

The ITW Cybersecurity Framework includes a number of activities designed to enhance the Company's resiliency related to cyber-related risks and ensure that the Company's information systems are secure from material cybersecurity threats. These activities include the following, among others:

• Annual cybersecurity training;

• Quarterly phish simulation testing;

• Ongoing response planning and tabletop exercises;

• Network and endpoint monitoring;

• Vulnerability management and testing; and

• Backup and recovery testing.

While the Company's information systems are exposed to cybersecurity threats and risks, the Company has not experienced any material cybersecurity incidents during 2023, 2022 or 2021, and any costs or operational impacts related to cybersecurity incidents were immaterial during this period.

Governance

ITW's Board of Directors is responsible for providing oversight and strategic guidance to management to support the long-term interests of the Company's stakeholders. As part of this responsibility, the Board of Directors annually reviews and evaluates the Company's cybersecurity policies and practices with respect to risk management as well as steps taken by management to monitor and control such exposures.

In addition to oversight by the Board of Directors, several cross-functional management teams focus on cybersecurity risk and report any identified cybersecurity incidents. Each of the Company's divisions has a Division Cyber Incident Response Team and protocols in place to communicate cybersecurity incidents to a central Cyber Incident Response Team. The Cyber Incident Response Team is led by the Chief Information Security Officer and is responsible for the initial assessment of cybersecurity incidents and oversight of any incident response.

On a quarterly basis, or sooner if appropriate, cybersecurity incidents are summarized and reported to the Cybersecurity Governance Committee comprised of senior executives. Additionally, the Audit Committee of the Board of Directors

receives quarterly cybersecurity reports from senior management which cover any identified cybersecurity incidents, results of third party vulnerability testing, and key developments in policies and practices during the quarter.

Due to the Company's decentralized operating structure and global operations, the Company operates out of a large number of facilities worldwide, none of which are individually significant to the Company or its segments. As of December 31, 2023, the Company operated approximately 410 plants and office facilities, excluding regional sales offices and warehouse facilities. Approximately 270 of the facilities were located outside of the United States. Principal foreign countries include China, Germany, France, and the United Kingdom.

The Company's properties are well suited for the purposes for which they were designed and are maintained in good operating condition. Production capacity, in general, currently exceeds operating levels. Capacity levels are somewhat flexible based on the number of shifts operated and on the number of overtime hours worked. The Company adds production capacity from time to time as required by increased demand. Additions to capacity can be made within a reasonable period of time due to the nature of the Company's businesses.

None. The Company's threshold for disclosing environmental legal proceedings involving a governmental authority where potential monetary sanctions are involved is $1 million.

None.

INTRODUCTION

Illinois Tool Works Inc. (the "Company" or "ITW") is a global manufacturer of a diversified range of industrial products and equipment with 84 divisions in 51 countries. As of December 31, 2023, the Company employed approximately 45,000 people.

The Company's operations are organized and managed based on similar product offerings and end markets, and are reported to senior management as the following seven segments: Automotive OEM; Food Equipment; Test & Measurement and Electronics; Welding; Polymers & Fluids; Construction Products; and Specialty Products.

Due to the large number of diverse businesses and the Company's decentralized operating structure, the Company does not require its businesses to provide detailed information on operating results. Instead, the Company's corporate management collects data on several key measurements: operating revenue, operating income, operating margin, overhead costs, number of months on hand in inventory, days sales outstanding in accounts receivable, past due receivables and return on invested capital. These key measures are monitored by management and significant changes in operating results versus current trends in end markets and variances from forecasts are discussed with operating unit management.

THE ITW BUSINESS MODEL

The powerful and highly differentiated ITW Business Model is the Company's core source of value creation. It is the Company's competitive advantage and defines how ITW creates value for its shareholders. The ITW Business Model is comprised of three unique elements:

• ITW's 80/20 Front-to-Back process is the operating system that is applied in every ITW business. Initially introduced as a manufacturing efficiency tool in the 1980s, ITW has continually refined, improved and expanded 80/20 into a proprietary, holistic business management process that generates significant value for the Company and its customers. Through the application of data driven insights generated by 80/20 practice, ITW focuses on its largest and best opportunities (the "80") and eliminates cost, complexity and distractions associated with the less

profitable opportunities (the "20"). 80/20 enables ITW businesses to consistently achieve world-class operational excellence in product availability, quality, and innovation, while generating superior financial performance;

• Customer-back Innovation** has fueled decades of profitable growth at ITW. The Company's unique innovation approach is built on insight gathered from the 80/20 Front-to-Back process. Working from the customer back, ITW businesses position themselves as the go-to problem solver for their "80" customers. ITW's innovation efforts are focused on understanding customer needs, particularly those in "80" markets with solid long-term growth fundamentals, and creating unique solutions to address those needs. These customer insights and learnings drive innovation at ITW and have contributed to a portfolio of approximately 19,600 granted and pending patents;

• ITW's Decentralized, Entrepreneurial Culture enables ITW businesses to be fast, focused, and responsive. ITW businesses have significant flexibility within the framework of the ITW Business Model to customize their approach in order to best serve their specific customers' needs. ITW colleagues recognize their unique responsibilities to execute the Company's strategy and values. As a result, the Company maintains a focused and simple organizational structure that, combined with outstanding execution, delivers best-in-class services and solutions adapted to each business' customers and end markets.

ENTERPRISE STRATEGY: 2012 - 2023

In late 2012, ITW began its strategic framework transitioning the Company to fully leverage the unique and powerful set of capabilities and operating practices of the ITW Business Model. The Company undertook a complete review of its performance, focusing on its businesses delivering consistent above-market growth with best-in-class margins and returns, and developing a strategy to replicate that performance across its operations. ITW determined that solid and consistent above-market organic growth is the core growth engine to deliver world-class financial performance and compelling long-term returns for its shareholders.

Key initiatives in the Company's enterprise strategy included portfolio management, business structure simplification, strategic sourcing and the diligent re-application of ITW's proprietary 80/20 Front-to-Back process.

• As part of the Portfolio Management initiative, ITW exited businesses that were operating in commoditized market spaces and prioritized sustainable differentiation as a must-have requirement for all ITW businesses. This process included both divesting entire businesses and exiting commoditized product lines and customers inside otherwise highly differentiated ITW divisions.

• Business Structure Simplification was implemented to simplify and scale up ITW's operating structure to support increased engineering, marketing, and sales resources, and improve global reach and competitiveness, all of which were critical to driving accelerated organic growth. ITW now has 84 scaled-up divisions with significantly enhanced focus on growth investments, core customers and products, and customer-back innovation.

• The Strategic Sourcing initiative established sourcing as a core strategic and operational capability at ITW, delivering an average of one percent reduction in spend each year since 2013 and continues to be a key contributor to the Company's ongoing enterprise strategy.

• With the initial portfolio realignment and scale-up work largely completed, the Company shifted its focus to preparing for and accelerating organic growth, reapplying the 80/20 Front-to-Back process to optimize its scaled-up divisions for growth, first, to build a foundation of operational excellence, and second, to identify the best opportunities to drive organic growth.

Since implementing the Company's enterprise strategy in 2012, the Company has demonstrated the compelling performance potential of the ITW Business Model and superior 80/20 management, resulting in meaningful incremental improvement in margins and returns as evidenced by the Company's operating margin and after-tax return on invested capital. At the same time, these 80/20 initiatives can also result in restructuring initiatives that reduce costs and improve profitability and returns.

OUR NEXT PHASE: 2024-2030

In the Next Phase of the Company’s evolution, the ITW Business Model and the Enterprise Strategy framework will be as formidable of a competitive advantage and performance differentiator as it has been over the last decade, if not more so. Volatility, risk and the pace of change in the global operating environment will continue to increase, and a decentralized

entrepreneurial culture allows the Company to be a fast adaptor – to read, react, respond and evolve. The Company’s ability to consistently execute and invest through the ups and downs of the business cycle is now a defining competitive advantage.

Throughout the Next Phase, the Company's focus is to build organic growth into a core ITW strength on par with the Company’s world-class financial performance and operational capabilities. Throughout this phase, the Company will sustain its foundational strengths built over the past decade, including the high-quality ITW Business Model practice. Customer-back Innovation (CBI) is the most impactful driver to achieve high-quality organic growth through the cycle by establishing trusted problem solver relationships with key customers to effectively invent solutions that address customers' most critical pain points or tackle the biggest growth opportunities. CBI successes, coupled with underlying market growth and share gains, are how the Company intends to achieve its high-quality organic growth.

MARKET RISK

The Company is exposed to certain market risks that exist as part of its ongoing business operations, including fluctuations in currency exchange rates, price volatility for certain commodities and changes in interest rates. The Company does not engage in speculative or leveraged transactions and does not hold or issue financial instruments for trading purposes.

Interest Rate Risk

The Company's exposure to market risk for changes in interest rates relates primarily to the fair value of the Company's fixed rate debt. Refer to Note 11. Debt in Item 8. Financial Statements and Supplemental Data for details related to the fair value of the Company's debt instruments. Additionally, rising interest rates would negatively impact the amount of interest expense related to new issuances of commercial paper and the outstanding Euro term loans borrowed under the Euro Credit Agreement.

Foreign Currency Risk

The Company operates in the U.S. and 50 foreign countries. The funding for the foreign manufacturing operations is provided primarily through the permanent investment of equity capital. The Company's products are typically manufactured and sold within the same country or economic union. Therefore, the Company's manufacturing operations generally do not have significant assets or liabilities denominated in currencies other than their functional currencies.

The Company designated the €1.0 billion of Euro notes issued in May 2014, the €1.0 billion of Euro notes issued in May 2015, the €1.6 billion of Euro notes issued in June 2019 and the €1.3 billion of Euro term loans borrowed under the Euro Credit Agreement in May 2023 as hedges of a portion of its net investment in Euro-denominated foreign operations to reduce foreign currency risk associated with the investment in these operations. Changes in the value of this debt resulting from fluctuations in the Euro to U.S. Dollar exchange rate have been recorded as foreign currency translation adjustments within Accumulated other comprehensive income (loss). On February 22, 2022, €500 million of the Euro notes issued in May 2014 were redeemed in full and on May 22, 2023, €500 million of the Euro notes issued in May 2015 were repaid on the due date. Refer to Note 11. Debt in Item 8. Financial Statements and Supplemental Data for additional information regarding the redemption of these notes. The amount of pre-tax gain (loss) related to these notes that was recorded in Other comprehensive income (loss) for the twelve months ended December 31, 2023, 2022 and 2021 was $(109) million, $205 million and $303 million, respectively.

MANAGEMENT REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Illinois Tool Works Inc. (the "Company" or "ITW") is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). ITW's internal control system was designed to provide reasonable assurance to the Company's management and Board of Directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

ITW management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2023. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013). Based on our assessment we believe that, as of December 31, 2023, the Company's internal control over financial reporting is effective based on those criteria.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2023 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their attestation report included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Illinois Tool Works Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Illinois Tool Works Inc. and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, changes in stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2023, 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 financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for these financial statements, 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 Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to 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. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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.

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.
