PER 100 EMPLOYEES SUPPLY CHAIN We partner with a global supply base to manufacture and distribute products to our customers and channel partners. In 2018, our more than 26,000 global suppliers provided us with raw materials, components, sub-assemblies, manufacturing services, finished goods, and indirect goods and services. Many of the suppliers upon whom we rely are located in foreign countries. The differences in business practices, shipping and delivery requirements, and laws and regulations have increased the complexity of our supply chain logistics and the potential for interruptions in our production scheduling. Therefore, we have continued to seek and realize supply chain efficiencies through strategic sourcing. We also have agreements with certain significant suppliers to help ensure continued availability.

PER 100 EMPLOYEES INNOVATION

VITALITY New product innovation has been the hallmark of our success and continues to drive our growth, with approximately 26 percent of our sales in 2018 coming from new products introduced in the prior three years.

Masco’s focus on innovation continued to differentiate us to our customers and end consumers. Delta Faucet Company recently introduced ShieldSpray® Technology, which is available on its pull-down kitchen faucets and provides a concentrated jet of water that powers away stubborn messes with less splatter than a standard spray. Our great customer partnership with The Home Depot carried over to Liberty Hardware, which was named The Home Depot Vendor of the Year in the Kitchen and Bath Department.

INTELLECTUAL PROPERTY Protecting our intellectual property is important to our growth and innovation efforts. We own a number of patents, trade names, brand names and other forms of intellectual property in our products and manufacturing processes throughout the world. In 2018, 1,061 patents and trademarks were granted to Masco worldwide.

The total number of patent and trademark applications that we filed during 2018 was 1,491. Foreign grants and filings accounted for 74 percent and 71 percent, respectively, of the total grants and filings.

Organizations supported by Masco and its Foundation during 2018 included: Habitat for Humanity International, HomeAid, City of Hope, Institute of Arts, The Henry Ford, Detroit Symphony Orchestra, Detroit Public Television, Detroit Zoological Society and many other local and national organizations. In addition to manufactured product donations by our business units, our employees raised and donated hundreds of thousands of dollars for local charities.

We also encourage our employees to make their own personal donations to nonprofit organizations by offering all U.S. employees the opportunity to double their impact through a matching gift program. Through this program, we match employee charitable gifts up to $5,000 per employee per year to any approved 501(c)(3) organization.

LABOR POLICY Masco prides itself on its reputation for honesty, integrity and excellence in everything that we do. We therefore expect and require that all goods produced on our behalf or on behalf of any of the brands in the Masco family be made in facilities that meet specific criteria for human rights, working conditions and protection of the environment.

24 CORPORATE SUSTAINABILITY REPORT SUPPLIER BUSINESS PRACTICES POLICY Our selection and continued use of our suppliers is based on the following standards with respect to all goods that we purchase:

1. Comply with all applicable laws and regulations 7. Protect against unlawful discrimination against 2. Protect against the use of workers younger than workers and encourage employment based on the minimum age required by law ability 3. Protect against the use of forced labor (including 8. Respect workers’ rights to associate freely slavery and human trafficking) 9. Maintain safe and clean workplaces, including any 4. Provide appropriate wages and benefits as residential facilities, in compliance with the law required by law 10. Protect our confidential and proprietary 5. Protect against excessive working hours that information exceed local laws or business customs 11. Provide us all requested information regarding 6. Protect against physical and mental punishment Conflict Minerals as set forth below of workers

In accordance with the SEC’s Conflict Minerals Rule, we have implemented processes to identify whether tin, tantalum, tungsten and gold (“Conflict Minerals”) are contained in our products and, if so, whether the Conflict Minerals may originate from sources that directly or indirectly finance or benefit armed groups operating in the Democratic Republic of the Congo and surrounding countries. We expect our suppliers to source Conflict Minerals from suppliers who meet our Supplier Business Practices Policy requirements, to implement traceability measures for Conflict Minerals, and to provide us with all requested information, including information about all suppliers in their supply chains, so that we can comply with the SEC’s Conflict Minerals Rule.

We do not discourage our suppliers from sourcing Conflict Minerals from the Covered Countries. Rather, we encourage our suppliers to source these minerals from smelters and refiners verified as compliant with the Conflict-Free Sourcing Program (CFSP) or a similar program whether or not in a Covered Country. We continue to support responsible in-region mineral sourcing from the DRC and adjoining countries.

We will not knowingly work with suppliers that do not respect these standards and those of our customers. We periodically assess our suppliers’ compliance with these standards and those of our customers. Any reported noncompliance is investigated, and appropriate action is taken. These standards apply whether the supplier is a Masco company, an affiliate or a third party.

Masco Corporation audits our supply base to ensure compliance with our Supplier Business Practices Policy. We use a risk-based approach to determine which suppliers will be audited in any given year, and then conduct audits using dedicated staff personnel and third-party resources. We conduct approximately 125 audits per year and maintain the results of all completed audits. We execute corrective action plans following the completion of each audit to drive continued improvement in our supply base.

Our Supplier Business Practices Policy can be found at http://masco.com/suppliers-policy/.

25 CORPORATE SUSTAINABILITY REPORT CHEMICAL RESPONSIBILITY

MANAGING PRODUCT RISK By utilizing various environmental, health and safety (EHS) tools to analyze the hazards of chemicals and ensure their proper handling, labeling, use and waste treatment, we strive to keep our employees and customers safe from potentially harmful chemicals. Our program to mitigate risks to our employees as well as our customers starts when a chemical is first considered for use in our products or processes. Each new chemical must be reviewed and approved, including meeting REACH regulations in Europe, where applicable, before it may be brought on site and used in our products or processes.

For example, at Bristan, all new suppliers are issued a REACH Declaration of Substances of Very High Concern (SVHC) and asked to sign a statement disclosing the presence or absence of SVHCs in their products or packaging and committing to provide relevant updates when necessary.

MANAGING EMERGING CONCERNS Masco follows strict regulations through software identification and requests from suppliers to constantly equip employees and customers to deal with emerging chemicals of concern. Before approving suppliers, business units that may use emerging chemicals of concern require suppliers to declare whether their products or packaging contain Substances of Very High Concern (SVHCs). For instance, Behr works closely with coating associations in both the United States and Canada to keep abreast of new regulations regarding chemicals used in its products. Bristan personnel attend technical meetings of the Bathroom Manufacturers Association, where amendments to the SVHC list are often discussed. Hansgrohe uses “REACH Radar” to identify SVHCs. When products or packaging are deemed to contain SVHCs, they are dealt with in a safe manner, according to regulation.

26 CORPORATE SUSTAINABILITY REPORT HUMAN CAPITAL

Masco Corporation and its business units have a strong focus on human capital, consistently working to attract, select, develop, engage and retain strong, diverse talent. Our talent practices align with our continuous improvement culture, in which we focus on ‘getting better every day’. In 2018, we identified opportunities to further strengthen and leverage the enterprise to improve our approach to human capital, which included a new enterprise Talent Strategy. We defined three key strategic talent priorities:

STRATEGIC TALENT PRIORITIES STRATEGIC OUTCOMES

Leadership: Build more great leaders, faster at Leadership: Strong bench of leaders who can all levels. win increasingly more complex, competitive and ever-changing situations. Diversity & Inclusion: Integrate D&I into who are and how we work. Diversity & Inclusion: Inclusive workplace that leverages diverse backgrounds and Future Workforce: Find, grow and engage a perspectives to help us keep innovating, problem-solving, creative, agile, team-focused enhance our culture, positively impact our workforce. communities and advance the business.

Future Workforce: Workforce with the right capabilities in the right roles to position us for the future.

LEADERSHIP

Our philosophy is that everyone in our organization is and can be a leader in their own way. We’ve focused on designing new approaches to support the selection, development and engagement of our employees.

Our Leadership Framework: We designed a new leadership framework that serves as the foundation for how we select, develop and measure the performance of our leaders. This framework includes clearly defined behaviors that differentiate good from great leadership and proven practices that accelerate growth. Experiential, interactive sessions and tools were developed for deployment throughout the organization.

Continuous Development: We began implementing a new and innovative approach to development that is continuous and “closer to the job” instead of simply relying on formal training. This approach is based on leveraging heat experiences; diverse, supportive networks; and reflection to embed learnings. Our approach starts with our top leaders as role models, followed by our leaders and employees learning and helping each other increase their performance, development and engagement every day.

Building a Coaching Culture: We’ve placed a specific focus on helping people have honest, two-way coaching and feedback discussions about performance and development. We have implemented practices to help us do this regularly and in various forums. We have tools in place to support our people in how best to engage with each other, and we work to reward, recognize, select and promote people who excel at these practices.

27 CORPORATE SUSTAINABILITY REPORT DIVERSITY AND INCLUSION Over the last three years, we’ve activated a company-wide conversation around what diversity and inclusion is, why it matters to Masco, and what it means to our employees. Our approach to D&I focuses on:

Our People & Culture: We know that creating an environment where all people, from all backgrounds, feel like they belong and can bring their authentic self to work is central to helping our workforce thrive. We’re working to enable this culture through a variety of methods. We’ve created ongoing forums to help our people have difficult discussions that may take them outside their comfort zone. Together we’re learning to listen more, be more empathetic and better understand each other’s differences as well as how we’re similar. Some examples of the types of forums include hosting Day of Understanding discussions across our businesses as part of our commitment to the CEO Action coalition. We’re also partnering with organizations such as the Human Library to create immersive experiences for our people to have a direct conversation with people experiencing stigma, discrimination or prejudice because of their differences. To move the needle, we know it takes more than conversations – it takes additional focused actions. We have improved our talent processes to help ensure we hire and promote more diverse talent and mitigate unconscious biases in our decision-making. We’ve established intersectional D&I teams that are leader and employee-led to steward this work in a way that is meaningful to the business.

Our Marketplace: Our products are in the homes of people in more than 140 countries across the globe, representing all different backgrounds and ways of life. We work each day to ensure our products not only meet our consumers’ needs but demonstrate an understanding of who they are, what they care about and what they truly want. We also welcome partnerships with businesses that reflect both the diversity of our employees and of the communities in which we live and work.

KEY NATIONAL PARTNERS Our Communities: Through our “Million Differences” campaign, Masco has pledged $1 million of our annual philanthropic contributions to organizations that provide programs and services dedicated to overcoming barriers to workplace inclusion. This effort allows us to not only give funding to support organizations with strong missions, but also serves as a platform for our employees to give their time and energy. More importantly, this creates powerful learning opportunities and exposure to different people and backgrounds while having a positive impact.

28 CORPORATE SUSTAINABILITY REPORT FUTURE WORKFORCE In support of our continuous improvement culture, we are building new capabilities to ensure our employees and our organization are positioned to win in the future. Each year, as part of our strategic, long-range planning processes, our businesses identify critical capabilities our organization and our people need to help us achieve our goals. Once identified, we put structured teams, plans and measures in place to ensure we’re building these capabilities, while also managing our short-term priorities. Some examples include capabilities related to commercial and operational excellence as well as problem-solving skills and using fact-based decision- making. We provide tools and training to help our people build these new and important skills. We also use Kaizen events as a core engine of our business to create engaging, effective forums for continuous improvement and capability building.

EMPLOYEE ENGAGEMENT In addition to building key capabilities, we are consistently focused on enhancing our employees’ overall experience. This goes beyond just understanding the level of employee engagement and retention levels. Our approach is holistic, and we’re implementing a variety of methods to listen to our employees and capture their feedback, including surveys, focus groups, employee and manager forums and town halls. We capture key insights, share them with our employees, identify critical gaps, and integrate the most impactful actions into our strategies and plans. In 2019, we plan to implement a more consistent approach across our business to enable more common measurement of key performance indicators.

EMPLOYEE RETENTION We remain focused on understanding and ensuring we are retaining our talent. In 2018, our rate of voluntary turnover in the U.S. was approximately 18 percent. Internationally, that rate was about 3 percent.

MATERIALITY

ENTITIES All of Masco’s business units are wholly owned, directly or indirectly, except for Hansgrohe SE, and all are included in both this CSR and financial reports. Masco owns 68 percent of Hansgrohe SE.

DEFINING REPORT CONTENT To prioritize the issues of most importance to our stakeholders, we hired a third-party consultant to assist our Sustainability Steering Committee (SSC) in assessing disclosure topics. Our assessment focused on identifying, prioritizing and validating aspects from the following key sources: Masco’s own documents on its sustainability strategy; feedback from the SSC, SSC Working and Advisory Groups, and employees; feedback directly from our shareholders and other stakeholders; initiatives from recognized industry organizations such as the Sustainability Accounting Standards Board, Global Reporting Initiative, Carbon Disclosure Project and the United Nations; documentation on the views of our stakeholders, including North American reporting authorities and surveys of U.S. environmental attitudes; and findings from peer benchmarking studies. In addition, specific comments and suggestions from stakeholders regarding our previously published sustainability reports have been influential in determining the structure and content of this report. From the content determined to be significant, we then identified the subset of content that would be appropriate to report, such as content with available data and without competitive risk. Finally, for each topic, we determined the boundary of applicability. For example, when considering Volatile Organic Compounds (VOCs) in regards to chemicals in our products, our boundary included relevant companies such as Behr Process Corporation.

31 CORPORATE SUSTAINABILITY REPORT MATERIAL ASPECTS AND BOUNDARIES Following is a list of topics Masco identified in the process of defining its 2018 CSR content, organized to align with the categories of the Global Reporting Initiative and other standards:

Corporate: Ethics and Integrity, Governance Environmental: Sustainable Products and Services, Structure, Brands, Products and Services, Energy, Materials, Water, Biodiversity, Emissions, Markets Served, Facilities, Countries of Operation, Effluents and Waste Workforce, Collective Bargaining, Supply Chain, Stakeholder Engagement, Data Protection Social: Community Engagement, Occupational Health and Safety, Training and Education, Economic: Economic Performance, Revenue from Employment, Non-Discrimination, Child Labor, Sustainable Products, Innovation Forced or Compulsory Labor

This report provides a summary of the sustainability performance and practices of Masco and its consolidated operating businesses as of December 31, 2018.

While included in this report, Hansgrohe has also produced its own Sustainability Report covering its facilities. The most recent Hansgrohe Sustainability Report is available in English (www.hansgrohe.com) and German (www.hansgrohe.de).

SIGNIFICANT CHANGES While Masco’s organizational profile changed in 2018, this report does not contain any significant changes in scope, boundary or measurement methods as compared to the 2017 CSR. This report does not contain a restatement of information relating to Masco’s major financial indicators and environmental data.

32 CORPORATE SUSTAINABILITY REPORT SELECTION Masco views its business–first and foremost–as one that serves its stakeholders. From our shareholders to our customers to our business partners to our employees, we know our financial and corporate sustainability performance depends on establishing good relationships with those we serve and rely on in the communities in which we work and live. We believe in engaging with all of our stakeholders honestly, respectfully and with integrity. Our stakeholder groups have been identified through a number of processes, namely feedback from Masco’s SSC, SSC Working and Advisory Groups and employees, as well as feedback directly from our shareholders and other stakeholders, studies from recognized industry organizations and evaluation of peer benchmark studies.

APPROACH We routinely seek input on what we make and sell, and how we operate internally and externally through employee surveys, shareholder meetings, market research and customer satisfaction analyses. The qualitative market research studies we conduct typically include questions related to the importance of sustainability to customer buying decisions.

Our approach has been to respond to various investor, highly-respected non-governmental organization and advocacy group inquiries for information. We also believe that our Corporate Sustainability Report is an effective method for providing meaningful communications with our stakeholders about our sustainability practices. In addition, Masco interfaces regularly with sustainability executives from other companies. This has enabled peer review and learning within a network of trusted professionals. We also engage in sustainability best-practice exchanges with other companies.

Masco’s suppliers are engaged through our enterprise-wide Supplier Business Practices Policy and audit process, and each Masco business unit has one or more managers or groups responsible for ensuring employee engagement in their respective organizations.

Through executive interviews, online bulletin boards and focus groups, Masco seeks to connect with its customers and build a two-way conversation. This conversation is enabled by a corporate Customer Satisfaction Index initiative across our North American business units that continually captures, evaluates and reports on how our channel customers, consumers, designers and installers perceive our product offerings. Our business units undertake qualitative and quantitative “Voice of Customer” market research to guide their development efforts for new products focused on the needs of their customers.

CONCERNS This report pays special attention to the topics of greatest concern to our principal stakeholders. These topics include innovative and sustainable products, energy usage and social responsibility.
