The Greystone Group Research
Advisory Approach
The Greystone Group is the leading boutique M&A advisor exclusively focused on the construction materials industry. Founded in 1996 by Tim Oitzman, the firm operates with a philosophy centered on deep industry specialization, long-term client relationships, and institutional knowledge of the aggregates, cement, and ready-mix concrete sectors. Their positioning is built on the thesis that only advisors with generational experience in construction materials—not generalist investment banks—can effectively execute complex transactions that maximize value for both sellers and strategic/PE buyers. The firm's intimate knowledge of industry consolidation patterns, buyer motivations, and valuation drivers gives them a competitive advantage no generalist advisor can match.
Sector Specialization
The Greystone Group's practice is highly concentrated in three primary subsectors:
Aggregates & Mining: Quarries, sand and gravel operations, and granite producers. The firm has unparalleled expertise in valuing aggregate reserves, understanding reserve depletion, permitting challenges, and identifying buyers willing to pay premium prices for high-quality reserves in growth markets. Examples include their advisory to Wake Stone (sale to Vulcan Materials), Blue Water Industries (sale of 20 Southeast operations to Martin Marietta for $2.05B), and Boral Industries (Oklahoma quarry to Martin Marietta).
Ready-Mix Concrete: Producers of ready-mix concrete serving construction markets regionally. The firm understands the logistics of cement distribution, ready-mix margins, customer concentration risk, and strategic buyer synergies. Recent examples include Superior Ready Mix (Vulcan), Charley's Concrete (SRM Concrete), Sierra Ready Mix (Summit Materials), and numerous other ready-mix divestitures.
Cement & Specialized Materials: Cement plants, concrete products, and specialized materials production. The firm has represented firms on both buy-side and sell-side transactions, including GCC's acquisition of Trident Cement, Continental Materials' divestiture to LafargeHolcim, and Tarrant Concrete's sale to LafargeHolcim.
Deal Track Record & Market Position
Greystone has managed over 75 construction materials transactions exceeding $10 billion in aggregate transaction value. This extensive deal history provides several strategic advantages: (1) unmatched knowledge of which buyers pay the highest valuations for specific asset types; (2) established relationships with PE firms and strategics that depend on Greystone for deal flow; (3) ability to structure creative solutions (earnouts, earndowns, phased closings) that other advisors haven't encountered.
Recent transaction activity (2021-2025) demonstrates consistent deal velocity: Wake Stone to Vulcan (Nov 2024), Blue Water Industries to Martin Marietta $2.05B (Apr 2024), Superior Ready Mix to Vulcan (Dec 2024), Carver Sand & Gravel to Heidelberg Materials (Aug 2024), BoDean and Northgate to CRH (Apr 2024), Arizona Materials to Summit (May 2023), and over 30 additional transactions over the past decade. The firm has particularly strong relationships facilitating deals to Vulcan Materials, Martin Marietta, LafargeHolcim, Cemex, Summit Materials, CRH, and QUIKRETE.
Advisory Services & Process
Greystone offers full-spectrum M&A advisory:
Sell-Side Advisory: Preparation of detailed valuations, buyer identification, exclusive process management with limited buyer outreach (5-20 qualified buyers), negotiation of LOIs and definitive agreements, and confidentiality protection. The firm custom-tailors offerings to highlight operational, financial, and investment attributes. Many engagements are structured as exclusive relationships.
Buy-Side Advisory: Acquisition strategy development, target identification leveraging proprietary industry databases and buyer network, valuation analysis, financing arrangement, negotiation and closing.
Structured Recapitalizations: Including minority growth investments, seller recaps, and leveraged transactions where only industry expertise can structure viable deals.
Buyer Network & Market Access
Greystone's buyer relationships are the primary driver of value for sellers. The firm has established relationships with:
- Strategic Consolidators: Vulcan Materials, Martin Marietta, LafargeHolcim, Cemex, Summit Materials, CRH, QUIKRETE, Knife River
- Financial Sponsors: Blue Water Advisors LP (PE investor in aggregates), numerous family offices and investment funds
- International Buyers: Grupo Cementos de Chihuahua (GCC), Boral Industries (Australian), Taiheiyo Cement (Japanese)
Their deal history shows 45+ transactions with strategic acquirers and 20+ with PE/financial buyers. Strong relationships with regional and national aggregates consolidators (Martin Marietta, Vulcan) command the highest valuations.
Competitive Positioning
Greystone differentiates through: (1) founder-led expertise (Tim Oitzman remains actively involved, with 30+ years in construction materials); (2) 100% industry focus (no generalist distraction); (3) operational understanding (team includes former plant managers, executives); (4) exhaustive buyer knowledge (who buys what, at what multiples, what they value); (5) long-term client relationships (many clients return for multiple transactions); (6) ability to creatively structure deals others can't (earnouts, reserves, phased closings).
Sweet Spot & Deal Sizing
The firm's historical sweet spot is family-owned aggregates producers, ready-mix networks, and cement operations in the $25M-$500M TEV range. They have managed deals from $15M (small quarries) to $2.05B (Blue Water to Martin Marietta). Minimum typical engagement is $10M-$15M TEV; below that, the transaction economics don't justify dedicated advisor time.
Team & Execution
The firm operates as a lean boutique with 4-5 core professionals:
- Tim Oitzman (Founder/President): 30+ years, 75+ deals
- Reed Shafer (VP): 20+ years construction materials, oversees valuation and transaction execution
- Dylan Whitehead (Senior Financial Analyst): Financial modeling and research
- Allison Goll (Senior Market Analyst): Industry analysis and due diligence
All senior team members have deep construction materials experience. The firm supplements with external specialists (environmental, permitting, engineering) as needed.
Geographic Coverage
Primary focus: United States. Strong transaction experience across all major aggregate-producing regions (Southeast, Midwest, Southwest, California, Colorado). Limited international advisory (primarily facilitating US sellers to international buyers).
Not a Fit If
The firm typically declines: transactions below $10M-$15M TEV (insufficient economics), asset-only sales of quarries without operating businesses, distressed situations requiring crisis advising, transactions in non-construction-materials verticals.
