Thompson: The first companies to see AI’s impact are heavy material firms

Key Concepts:

• AI and Data Center Growth Impact on Heavy Materials
• Heavy Materials Sector Performance and Investor Sentiment
• Residential vs. Non-Residential Construction Market Dynamics
• Impact of Interest Rate Cuts on Heavy Materials Demand
• Aggregate Companies and Construction Partners as Investment Opportunities
• Testing and Inspection Services

1. AI and Data Center Growth Impact on Heavy Materials

• Kathryn Thompson asserts that heavy material companies are among the first to benefit from the growth of AI and data centers.
• CRH's CEO has acknowledged this trend.
• Martin Marietta is repurposing an aggregate quarry in Texas to build a Giga factory.
• Vulcan Materials reports $35 billion in projects directly related to AI, data centers, and energy infrastructure.

2. Heavy Materials Sector Performance and Investor Sentiment

• The materials sector has been lagging the market year-to-date, up approximately 5-6%.
• The sector is perceived as a "forgotten cyclical," despite potentially benefiting from rate cuts.

3. Residential vs. Non-Residential Construction Market Dynamics

• The residential end market has been in a recession for 2-3 years, historically representing about 25% of the heavy materials companies' end market.
• Residential contribution has decreased to 15-17%.
• Heavy non-residential construction is offsetting the residential weakness.
• All indicators suggest continued growth in non-residential, overlapping with a potential residential recovery.

4. Impact of Interest Rate Cuts on Heavy Materials Demand

• If interest rates fall below 6%, demand for heavy material stocks is expected to increase significantly.
• Lower rates for residential housing are considered a tailwind for the business.

5. Aggregate Companies and Construction Partners as Investment Opportunities

• Aggregate names like CRH, Martin Marietta, and Vulcan Materials are key players.
• Construction Partners (ROA) and Knife River (KNF) are highlighted as "off the beaten path" names.
• Anecdotal evidence: A 16-mile road construction project solely to support a new data center in Idaho.

6. Testing and Inspection Services

• Testing and inspection services are also expected to benefit from the infrastructure build-up.

Synthesis/Conclusion:

The heavy materials sector is poised to benefit significantly from the growth of AI, data centers, and energy infrastructure. While the sector has been lagging, the decline in residential construction is being offset by strong non-residential activity. Lower interest rates are expected to further boost demand for heavy material stocks. Investment opportunities exist not only in major aggregate companies but also in construction partners and testing/inspection services.
