Analysis

Investment advisor Paradiem, LLC significantly increased its stake in Owens Corning (NYSE: OC) during Q3 2025, adding 85,047 shares to bring its total position to 94,067 shares, valued at $13.31 million. This transaction elevated OC's representation within Paradiem's 13F reportable assets from 0.3% to 3.1%, indicating a strong conviction despite OC remaining outside the fund's top five holdings.

This increased investment comes as OC shares have underperformed, declining 33.04% year-over-year to $126.96 as of October 17, 2025, and trailing the S&P 500 by 45.03 percentage points. The stock's weakness is attributed to macroeconomic headwinds, including higher interest rates and persistent inflation impacting the construction sector.

Despite these challenges, Owens Corning reported robust Q2 financials, with sales growing 10% year-over-year to $2.75 billion and diluted earnings per share from continuing operations increasing 34% year-over-year to $3.91. The company also strategically divested less profitable businesses in China and South Korea to sharpen its focus on North American and European markets.

Paradiem's move suggests a belief that OC is undervalued, capitalizing on its solid operational performance and strategic adjustments, while anticipating a potential rebound in the construction industry driven by expected Federal Reserve interest rate cuts. This positions OC as a compelling investment opportunity during its current downturn.

Key Decisions for Investors

• Investors should consider Paradiem's increased stake in Owens Corning as a potential signal of value, particularly given OC's strong Q2 earnings growth despite broader market underperformance.
• Monitor upcoming Federal Reserve interest rate decisions and their impact on the construction sector, as these are critical catalysts for OC's stock performance.
• Evaluate OC's current valuation and its long-term growth prospects in its core North American and European markets, considering its strategic divestitures.
