    Owens Corning navigated a challenging Q4 FY25 with strong adjusted EBITDA margins and significant cash flow generation, driven by operational efficiencies and strategic portfolio adjustments.

    Concerns

    5

    • Q4 FY25 Roofing sales decreased 27% due to lower shingle volumes and unusually low storm activity.

    • Q4 FY25 Doors revenue declined 14% due to weak new construction and R&R activity, with EBITDA margin at 7%.

    • Full-year FY25 adjusting items totaled $1.2 billion, primarily due to $1.1 billion in noncash goodwill impairment charges in the Doors business.

    • Anticipate Q1 FY26 Roofing EBITDA margin in the low 20s, down from Q4, due to $30 million headwind from higher-cost inventory from production curtailments.

    • Q1 FY26 revenue expected to be down mid-teens for Doors and mid- to high single digits for Insulation year-over-year.

    Risks & headwinds

    6
    Weakening U.S. residential trends and distribution destockingH2 FY25, continuing into Q1 FY26

    Weaker market conditions in H2 FY25

    Mitigation: Leveraging strong market positions, improved operating efficiencies, and favorable product mix shifts to generate higher margins on lower market volumes.

    Unusually quiet storm seasonH2 FY25, impacting Q1 FY26 storm carryover

    No major storms making landfall in the U.S. in H2 FY25 for the first time in a decade, weighing heavily on nondiscretionary roofing repair demand.

    Mitigation: Expectation for more normal storm activity in FY26 to improve demand throughout the year.

    Lower housing starts and soft discretionary R&R activityFY25, continuing into Q1 FY26, improving in H2 FY26

    Pressuring demand in the Doors business, Q1 FY26 residential new construction at lowest level in 6 years.

    Mitigation: Streamlining operations, reducing costs, increasing share of wallet with customers, and implementing network optimization in Doors. Expecting market improvements in H2 FY26.

    Tariff disruption and exposureFY25, Q1 FY26, ongoing

    FY25 gross tariff exposure of $110 million, net impact of $30 million (primarily Doors). Q1 FY26 gross tariff exposure of $20 million, net impact of $10 million (primarily Doors).

    Mitigation: Sourcing and supply chain teams demonstrating agility in mitigating tariff exposure. Monitoring Supreme Court decision for potential impact on overall tariff exposure.

    Inflationary pressuresQ4 FY25, continuing into Q1 FY26

    Continued inflation resulting in negative price/cost in Q4 FY25 for Roofing and Insulation, and for Doors.

    Mitigation: Implementing price increases (e.g., April 1st for Roofing) to offset inflation, strong operational performance, and prior structural cost actions.

    Production curtailment costsQ1 FY26

    Roughly $30 million headwind in Q1 FY26 for Roofing as higher cost inventory flows through the P&L.

    Mitigation: Disciplined inventory management to match production to anticipated peak season needs, balancing cash flows and customer support.

    What to watch in Q1 FY26

    5

    Roofing market shipments and restocking

    Q2 FY26
    CurrentQ1 FY26 ARMA market shipments anticipated down low 20% YoY; restocking delayed due to severe winter weather.
    TargetImprovement in restocking activity and shipping patterns in March/April, leading to higher volumes in Q2.

    Why it matters

    Indicates recovery in roofing demand and channel inventory normalization, crucial for full-year performance and price realization.

    So when we look at our order entry and our backlogs, they continue to grow throughout the quarter. We expect to have a pretty good March shipping pattern emerge. And then we think that's going to continue into April and early May. So I think the setup to restock is in place. It's just being a little delayed, and that's why it's impacting a little bit more of the year-over-year decline from our manufacturing shipments.

    Q&A highlights

    8

    How comfortable is management with visibility into Q2-Q4 FY26, and which consensus estimates is the company aligning with for the full year?

    Management expects market conditions to progressively improve throughout FY26, with Roofing demand increasing, R&R improving in the second half, and new construction remaining flat with a favorable single-family mix. The full-year outlook for revenue and adjusted EBITDA is largely aligned with the average of current consensus estimates.

    “I think that's our view as we kind of come into the year and why we wanted to give visibility to a guide of kind of this general consensus estimate. So if we look across all the estimates that have been created for the company. We think the average is right in line with kind of how we see the year playing out on a full year basis.”

    Detailed Narrative

    01

    Strategic Portfolio Reshaping and Divestitures

    Owens Corning continued to reshape its portfolio in FY25, completing the sale of its building materials business in China and Korea to streamline its geographic footprint. The company also announced the divestiture of its glass reinforcements business, which serves industrial markets, with regulatory approvals advancing for an expected close in the coming months⏳. These moves aim to focus the company on more residential product categories that leverage its customer and channel expertise, strengthening long-term financial performance.

    02

    Operational Efficiency and Cost Synergies

    The company exceeded its commitment of $125 million in run-rate enterprise cost synergies from the Doors business by mid-2026, with visibility to an additional $10 million to $15 million upside. Furthermore, Owens Corning is on track to deliver an additional $75 million in structural cost improvements within its operations, including network optimization, automation, and productivity initiatives. This includes the closure and consolidation of five manufacturing and fabrication facilities in the Doors segment, aiming to significantly grow earnings and cash flow as markets recover.

    03

    Commercial Strategy and 'OC Advantage'

    Owens Corning is leveraging its 'OC Advantage' through unparalleled commercial strength, iconic brand recognition, and deep channel expertise. The Pink Advantage Dealer Program, which supports over 4,000 privately owned lumber and building materials dealers, saw a 38% increase in enrollments in 2025 by integrating product and marketing offerings across residential insulation, roofing, and doors. A similar model is being applied to homebuilders, aiming to drive pull-through demand and increase revenues by offering an integrated product suite and enhanced marketing tools.

    04

    Innovation and Digital Transformation

    The company launched over 30 new or improved products in 2025, maintaining a 20%+ product vitality index. To accelerate innovation, José Méndez-Andino was promoted to Chief Innovation Officer, leading a center of excellence. Owens Corning is also advancing digital technology capabilities, including generative and agentic AI, to drive efficiency and strengthen market leadership. Annie Baymiller was promoted to CIO to lead these efforts, applying AI for supply chain optimization and planning to scale across businesses.

    05

    Capacity Expansion and Manufacturing Modernization

    Through its factory modernization initiative, Owens Corning improved its manufacturing cost position and increased capacity with targeted capital-efficient investments. In Roofing, a new laminate shingle line in Ohio and a high-speed nonwovens line in Arkansas started up. Insulation expanded XPS foam insulation capabilities with a new low-cost plant in Arkansas. In Doors, network optimization actions, including facility closures and automation investments, are driving structural cost improvements, enhancing the winning cost position.

    06

    Market Outlook and Recovery Expectations

    While FY25 presented challenging market conditions, particularly in U.S. residential and distribution destocking, management expects conditions to improve in the second half of FY26. Key drivers include a more normalized storm season for Roofing, slight improvement in discretionary R&R, and flat North American residential new construction with a favorable mix shift to single-family homes. The company anticipates strong financial results with multiple levers to outperform the market as conditions recover.
