Properties, in its own words

We own a 100-acre, multi-building campus in Lancaster, Pennsylvania comprising the site of our corporate headquarters and most of our non-manufacturing operations.

As of December 31, 2025, we operated 22 manufacturing plants, including 19 plants located within the U.S. and three plants in Canada.

The rest of Item 2

WAVE operates seven additional plants in the U.S. to produce suspension system (grid) products, which we use and sell in our ceiling systems.

Fourteen of our plants are leased and the remaining eight are owned.

Operating Segment · Number ofPlants · Location of Principal Facilities

Mineral Fiber · 5 · U.S. (Florida, Georgia, Ohio, Pennsylvania and West Virginia)

Architectural Specialties · 17 · U.S. (California (3), Colorado, Illinois (2), Missouri (2), Ohio (3), North Carolina, Texas, Utah) and Canada (British Columbia, Ontario and Quebec)

Sales and administrative offices are leased and/or owned, and leased facilities are used to supplement our owned warehousing facilities.

Production capacity and the extent of utilization of our facilities are difficult to quantify with certainty. In any one facility, utilization of our capacity varies periodically depending upon demand for the product that is being manufactured. We believe our facilities are adequate and suitable to support the business. Additional incremental investments in plant facilities are made as appropriate to balance capacity with anticipated demand, improve quality and service, and reduce costs.

The story

1860–1919

In 1860, Thomas M. Armstrong, the son of Scottish-Irish immigrants from Derry, joined with John D. Glass to open a one-room shop in Pittsburgh, Pennsylvania, carving bottle stoppers from cork by hand. Their first deliveries were made in a wheelbarrow. Armstrong was a business pioneer in some respects; he branded each cork he shipped as early as 1864, and soon was putting a written guarantee in each burlap bag of corks he shipped from his big, new factory. The company grew to be the largest cork supplier in the world by the 1890s. The company incorporated in 1891.

Cork began being displaced by other closures, but the company introduced insulating corkboard and brick. In 1906, two years before he died, Thomas Armstrong concluded that the solid foundation of the future was covered with linoleum, and construction began on a new factory in a cornfield at the edge of Lancaster, Pennsylvania. In 1909, Armstrong linoleum was first offered to the trade.

After corkboard, the logical move was to fiberboard, and then to ceiling board. Cork tile and linoleum led to vinyl flooring, then ceramic tile, laminate flooring, and carpeting.

In 1917, Armstrong Cork signed with the Batton Company advertising agency, a relationship that continues to this day through their corporate descendants.

1920s-1990s

In the 1920s, the Armstrong Cork Products Company and Sherwin-Williams company were the largest industrial customers for hemp fiber.

In 1938, Armstrong bought Whitall Tatum, which had been one of the larger manufacturers of glass insulators for communications and power lines since entering that field in 1922. The Whitall Tatum name was phased out, first by removing "Co." from the molds, then replacing the "WT" logo with the Armstrong logo, and finally replacing the molds with ones bearing the Armstrong name. In April 1969, the business was sold to Kerr Glass Manufacturing Corporation. Kerr eventually moved insulator production from Millville to their Dunkirk, Indiana, factory in the mid-1970s, and production ceased by the end of the decade.

During World War II, Armstrong made 50-caliber round ammunition, wing tips for airplanes, cork sound insulation for submarines, and camouflage.

In 1952, Henning W. Prentis of Armstrong Cork Company and industrialists such as Alfred P. Sloan of General Motors, Frank W. Abrams of Standard Oil Company of New Jersey, and Henry Ford II of Ford Motor Company formed the Council for Financial Aid to Education, which increased corporate gifts to colleges from $24 million annually to $136 million annually over 10 years.

In 1958, Armstrong Cork Company created Armstrong Contracting and Supply Corporation. Armstrong Cork had done insulation contracting since the early 20th century, originally focusing on cork products. Gradually, greater emphasis was placed on high-temperature insulation. In 1969, this business was sold in a leveraged buyout to 31 existing and retired employees of the contracting company, which became Irex Corporation.

C.U.E., Inc. (from Custom Urethane Elastomers) started as the Polyurethane Division of Armstrong Cork in the 1960s. The Fluorocarbon Company of Anaheim, California, bought the division in 1972. On April 7, 1986, a group of seven employees acquired the division in a leveraged buyout.

In 1964, Armstrong bought Phoenix Chair Company, following up with Founders Furniture Company in 1965, Western Carolina Furniture Company in 1966, and both Thomasville Furniture and Caldwell Furniture in 1968. In the 1970s, they expanded with a low-end bedroom-furniture line. They bought Gilliam Furniture in 1986, bought and repurposed the former Stehle polyester factory in Carysbrook, Virginia, later that year, bought Westchester Group in 1987, and Gordon's in 1988, and made a major expansion to Thomasville that year. In 1995, Thomasville Furniture was sold to Interco (which became Furniture Brands International), a leading furniture manufacturer, with such brands as Broyhill and Lane.

In 1998, Armstrong acquired Triangle Pacific Corp., a leading manufacturer of hardwood flooring and kitchen/bathroom cabinets.

Asbestos trust and bankruptcy—2000-2006

The company filed for reorganization December 6, 2000, with the federal bankruptcy court in Delaware for reorganization under Chapter 11 because pending asbestos injury claims appeared to exceed the value of the company, and were growing.

In 2002, Armstrong created a billion-dollar trust to resolve thousands of asbestos-related lawsuits filed against the firm. The trust was funded with a combination of stock and cash.

Armstrong World Industries, Inc. emerged from Chapter 11 reorganization on October 2, 2006. The Armstrong World Industries, Inc. Asbestos Personal Injury Settlement Trust in 2006 held approximately 66% of AWI's outstanding common shares. Armstrong's "Fourth Amended Plan of Reorganization, as Modified", dated February 21, 2006, and confirmed by U.S. District Court Judge Eduardo Robreno in August 2006, become effective October 2, 2006. The Plan included a comprehensive settlement resolving AWI's asbestos liability by establishing and funding a trust to compensate all current and future asbestos personal injury claimants. Its stock began trading on the New York Stock Exchange on October 18, 2006, under the ticker symbol AWI.

"In addition to resolving AWI’s asbestos liability, we used the time in Chapter 11 to restructure our flooring business to make it more competitive", AWI CEO Michael D. Lockhart said. "We made substantial improvements in our cost structure by closing several plants and streamlining our workforce in the U.S. We have also expanded capacity to manufacture wood flooring, broadened our product lines and improved product quality and customer service".

2007-2024

On February 15, 2007, Armstrong World Industries, Inc. announced that it was initiating a review of its strategic alternatives. On March 27, 2007, Armstrong World Industries, Inc. and NPM Capital N.V. agreed to sell Tapijtfabriek H. Desseaux N.V. and its subsidiaries, the principal operating companies in Armstrong's European Textile and Sports Flooring business segment, to NPM Capital N.V. The sale was finalized in April 2007. In 2009, Armstrong's annual net sales total was US$2.8 billion. Matthew Espe became AWI president and CEO in July 2010. In 2011, Armstrong's net sales were $2.86 billion, with operating income of $239.2 million. Armstrong Cabinets was sold by Armstrong World Industries to American Industrial Partners on October 31, 2012.

Armstrong spun off its flooring business into a new company, Armstrong Flooring (NYSE: AFI) on April 1, 2016. It began trading on the New York Stock Exchange with 3,700 employees and 17 manufacturing facilities in three countries. That day, Matthew Espe was succeeded as CEO of Armstrong World Industries by Vic Grizzle.

In 2020, Armstrong World Industries Inc. remained based in Lancaster, Pennsylvania. That February, it purchased group annuity contracts from Athene Annuity & Life Co. to transfer the majority of its U.S. pension plan liabilities. It transferred $1 billion in liabilities from the retirement income plan, affecting about 10,000 beneficiaries. In 2022, AWI had $1.2 billion in revenue. In 2024, it had 3,100 employees and 17 facilities, with its research lab in Manor Township. In January 2024, AWI acquired a stake in Overcast Innovations, a ceiling system designer in Seattle.

Risk factors and legal proceedings

The risks Armstrong World Industries names in Item 1A of its 10-K filed Feb 24, 2026: 24 risks under these headings, as written.17

  • Risks Related to Our Operations
  • Sales fluctuations and changes in our relationships with key customers could have a material adverse effect on our financial condition, liquidity or results of operations.
  • If the availability of our manufacturing inputs or sourced products decreases, or the cost of those inputs or sourced products increases and we are unable to pass along increased costs resulting from supply chain or inflationary pressures, our financial condition, liquidity or results of operations could be materially and adversely affected.
  • The performance of our WAVE joint venture is important to our financial results. Changes in the demand for, or quality of, WAVE products, or in the operational or financial performance of the WAVE joint venture, could have a material adverse effect on our financial condition, liquidity or results of operations. Similarly, if there is a change with respect to our joint venture partner that adversely impacts its relationship with us, WAVE’s performance could be materially and adversely impacted.
  • We continuously pursue productivity initiatives and periodically engage in cost-saving initiatives. Execution of these initiatives may result in interruptions in production and/or may result in lower-than-expected savings in our operating cost structure or may not improve our operating results.
  • Increased labor costs, labor disputes, work stoppages or union organizing activity, as well as increased labor shortages, or an inability to attract and retain talented employees could delay or impede production and could have a material adverse effect on our financial condition, liquidity or results of operations.
  • We are subject to certain regulatory, financial and other risks related to climate change, climate transition, and other sustainability matters. Should our efforts to address these risks fail to align with new regulations or stakeholder expectations, fail to achieve the anticipated benefits, or result in unanticipated costs, our corporate reputation, financial condition, liquidity or results of operations could be materially and adversely impacted.
  • Risks Related to Our Strategy
  • We may not experience the anticipated benefits from our strategic initiatives, including investments in product innovation and digitalization.
  • We are likely to pursue strategic transactions, including mergers, acquisitions, joint ventures, strategic alliances or other investments, which could create risks and present unforeseen integration obstacles or costs, any of which could have a material adverse effect on our financial condition, liquidity or results of operations.
  • Risks Related to Financial Matters
  • We require a significant amount of liquidity to fund our operations, and our indebtedness may have a material adverse effect on our ability to operate and invest in our business, execute on our strategic initiatives, and return cash to shareholders.
The other 15 risks
  • We cannot guarantee future cash dividend payments or future repurchases of our common stock pursuant to a share repurchase program.
  • Negative tax consequences can have an unanticipated effect on our financial results.
  • Significant changes in factors and assumptions used to measure our defined benefit plan obligations, actual investment returns on pension assets and other factors could negatively impact our operating results and cash flows.
  • Risks Related to Legal and Regulatory Matters
  • Potential regulatory actions, product and service claims, environmental claims and other litigation could be costly and have a material adverse effect on our financial condition, liquidity or results of operations. Insurance coverage may not be available or adequate in all circumstances.
  • We may be subject to liability under, and may make substantial future expenditures to comply with, environmental laws and regulations, which could have a material adverse effect on our financial condition, liquidity or results of operations.
  • Our intellectual property rights may be infringed, misappropriated, invalidated or otherwise circumvented, which could have a material adverse impact on our financial condition, liquidity or results of operations.
  • We are subject to risks associated with our operations in Canada and Latin America. Legislative, political, regulatory and economic volatility, as well as vulnerability to infrastructure and labor disruptions, could have a material adverse effect on our financial condition, liquidity or results of operations.
  • Risks Related to General Economic and Other Factors
  • Unstable market and economic conditions could have a material adverse impact on our financial condition, liquidity or results of operations.
  • Our business is dependent on construction activity in North America. Downturns or delays in construction activity could have a material adverse effect on our financial condition, liquidity or results of operations.
  • Our markets are highly competitive. Competition could reduce demand for our products or impact our profitability. Failure to compete effectively by meeting consumer preferences, developing and marketing innovative solutions, maintaining strong customer service and distribution relationships, and expanding our solutions capabilities and reach could have a material adverse effect on our financial condition, liquidity or results of operations.
  • Customer consolidation, and competitive, economic and other pressures facing our customers, and our potential failure to attract new customers in our markets, may negatively impact our net sales, operating margins and profitability.
  • We rely on operating and information systems that may experience a failure, a compromise of security, or a violation of data privacy laws or regulations, which could interrupt or damage our operations and have a material adverse effect on our financial condition, liquidity or results of operations.
  • Our business is dependent upon third-party vendors and suppliers whose failure to perform adequately could have a material adverse effect on our financial condition, liquidity or results of operations.
  • The geographic concentration of our business could subject us to risks, including those associated with climate change, which may be greater than our competitors and could have a material adverse effect on our financial condition, liquidity or results of operations.
  • Public health epidemics or pandemics could have a material adverse effect on our financial condition, liquidity or results of operations.

Legal proceedings

See the “Specific Material Events” subheading under the “Environmental Matters” section of Note 26 to the Consolidated Financial Statements, which is incorporated herein by reference, for a description of our significant legal proceedings. We are party to various other lawsuits, claims, investigations and other legal matters that arise in the ordinary course of business, including matters involving our products, intellectual property, relationships with suppliers, relationships with distributors, other customers or end users, relationships with competitors, employees and other matters. We do not believe that any such current claims, individually or in the

aggregate, will have a material adverse effect on our financial condition, liquidity or results of operations. However, regardless of outcome, litigation and related matters can have an adverse impact on us due to defense and settlement costs, diversion of management resources, negative publicity, reputational harm and other factors.
