Cardinal (CDNL) Q4 2025 earnings review
Massive Top-Line Expansion While IPO and M&A Costs Drag GAAP Earnings
Cardinal wrapped up a milestone IPO year with exceptional top-line performance: revenue surged 45% to $456 million, and backlog swelled 33% to $682 million. However, the GAAP bottom line failed to match this velocity. Net Income grew a sluggish 10% as depreciation, interest, and non-recurring IPO/M&A costs crushed net margins from 9.0% to 6.8%. Looking past GAAP noise, the core operational engine remains robust—Adjusted EBITDA grew 44% to $81.5M. The transformative $245.5 million acquisition of A.L. Grading Contractors in Q1 2026 is poised to aggressively re-accelerate growth and push margins over 20%, but it introduces immense integration risk.
🐂 Bull Case
The company exits 2025 with a record $682 million backlog, offering a massive 1.5x revenue coverage ratio. Organic growth alone was an impressive 33% before factoring in new acquisitions.
The ALGC acquisition brings a stellar 26.3% LTM Adjusted EBITDA margin on $160 million in revenue, which single-handedly upgrades Cardinal's consolidated margin profile heading into 2026.
🐻 Bear Case
Depreciation and amortization nearly doubled to $32.4 million, and interest expenses spiked. As the company aggressively acquires asset-heavy regional players, capital expenditures ($43.8M in 2025) and D&A will continue to heavily weigh on unadjusted earnings.
With ~66% of 2025 revenues tied to Residential development, the company's fate is uncomfortably tethered to local housing dynamics and interest rate cycles, despite a stated goal to diversify.
⚖️ Verdict: 🟢
Bullish. While the GAAP margin degradation is an optics issue, the operational momentum is undeniable. Cardinal is successfully executing a regional roll-up strategy in high-growth Southeast markets, and the addition of ALGC provides a clear path to 20%+ Adjusted EBITDA margins in 2026.
Key Themes
A.L. Grading Acquisition Redefines 2026 Trajectory
The $245.5M acquisition of ALGC (closed Feb 2026) is the single biggest growth driver for the coming year. This establishes Cardinal's first beachhead outside the Carolinas (Atlanta MSA) and immediately injects $160M of TTM revenue at a 26.3% Adjusted EBITDA margin. Because ALGC was purchased at an attractive ~5.8x EBITDA multiple, it materially raises the combined company's profitability ceiling.
Southeastern Macro Tailwinds
Cardinal is successfully surfing structural demographic shifts. Management explicitly cited Southeastern population growth and corporate reshoring as fundamental drivers. The North Carolina State Transportation Improvement Plan (a decade-long pipeline) is fueling DOT and municipal work, providing a durable safety net underneath the company's rapid expansion.
Vertical Integration: Owned Asphalt Plant Strategy
Innovation in infrastructure often means controlling the supply chain. Through the integration of the Red Clay Industries acquisition, Cardinal is scaling its Paving & Materials segment. A major operational milestone is slated for late Q2 2026 when Cardinal's first owned asphalt plant comes online. This shift from subcontractor dependency to self-performance is a structural driver for long-term gross margin expansion.
GAAP Earnings Quality and Capital Intensity
Net income margin compressed from 9.0% in 2024 to 6.8% in 2025. A significant data point contradicting the rosy 45% revenue growth narrative is the 73% explosion in Depreciation & Amortization ($18.6M to $32.4M) and a surge in Capital Expenditures from $20.8M to $43.8M. The heavy equipment demands of this business model mean that "Adjusted EBITDA" ignores real, recurring cash costs required to maintain the fleet.
Extreme Concentration in Residential Markets
Despite management's claim of diversifying end uses, Residential work still constituted roughly 66% of FY2025 revenue ($301M). While currently buoyed by Southeast migration, this segment is historically cyclical. Any sustained pressure on regional homebuilder starts will immediately threaten the company's backlog conversion.
M&A Integration Fatigue
Cardinal has absorbed four major acquisitions in rapid succession (Purcell, Page, Red Clay in 2025, and ALGC in early 2026). The Red Clay acquisition alone brought a complex Tax Receivable Agreement and a new $195M credit facility. Integrating wildly different regional operators, standardizing their fleets, and centralizing their back-office functions introduces enormous execution risk that could derail projected 2026 synergies.
Other KPIs
Accelerating. Up 33% from $512 million at the end of 2024, continuing a powerful 44% CAGR from 2021-2025. This yields a 1.5x backlog-to-revenue ratio, giving management exceptional visibility into 2026 execution and largely de-risking the aggressive top-line guidance.
Accelerating. Up 47% YoY, slightly outpacing total revenue growth. Adjusted Gross Profit Margin expanded 37 basis points to 21.1%. This confirms that the company is successfully passing through costs in its negotiated contracts (which make up 97% of revenue) and leveraging economies of scale.
Reversing. Surged from just $20.9 million at the end of 2024, entirely driven by the $139.8 million raised during the December 2025 IPO. However, a significant portion of this liquidity has already been earmarked for the cash component ($128.6M) of the ALGC acquisition in early 2026, meaning the company will likely need to tap its credit facilities shortly after year-end.
Guidance
Accelerating. The midpoint of $671.5 million implies massive 47.2% YoY growth. Crucially, this includes ~10.5 months of contribution from the ALGC acquisition. Assuming ALGC contributes roughly $140M of that total, the implied organic base business growth is still a very healthy 15-18%.
Accelerating. Moving aggressively upward from 17.9% in 2025. This 210+ bps expansion relies heavily on the mathematical blend of adding ALGC's historically 26.3% margin business, alongside internal vertical integration benefits (like the Q2 asphalt plant rollout).
Key Questions
ALGC Margin Sustainability
ALGC has operated at an exceptional 26.3% Adjusted EBITDA margin. How much of that is driven by structurally different pricing dynamics in the Atlanta market versus the Carolinas, and is that margin profile sustainable under public company cost burdens?
Capital Expenditure Normalization
CapEx more than doubled to $43.8 million in 2025. As you fold in the ALGC fleet and bring the new asphalt plant online, what is the expected run-rate for maintenance CapEx versus growth CapEx going into 2026?
Residential Pipeline Risks
With 66% of revenues tied to Residential, what leading indicators are you tracking in your core Southeast markets that give you confidence this cycle won't stall if interest rates remain higher for longer?
Subcontractor vs. Self-Perform Mix
You are heavily emphasizing vertical integration with the Red Clay and ALGC deals. What percentage of total project value is still being subcontracted today, and what is your ultimate target for self-performance?
