2. Thesis Layer

Thesis Status: Tactical / Setup-Led Macro Thesis: None

At this date, CDNL is a TACTICAL, setup-led name with NO named secular thesis attached to the equity. There is no macroeconomic or secular theme (e.g., "AI Infrastructure Build-out" or "Green Energy Transition") explicitly driving the narrative in the provided evidence. The investment case must be judged strictly on the quality of the setup (which is currently absent) and the underlying business fundamentals. Do not invent a thesis; the conviction must derive from the operational execution and financial metrics provided in the earnings and filings.

3. The Business

Company Overview: Cardinal Infrastructure Group Inc. is a leading provider of site development and infrastructure services operating primarily in the southeastern United States, with a focus on North Carolina and expanding into Georgia. The company serves residential, commercial, industrial, municipal, and state infrastructure markets.

Business Model & Operations:

• Service Scope: The company provides a comprehensive suite of services including construction grading and the installation of underground utilities.
• Market Expansion: Historically, the company was approximately 75% focused on residential work. As of the first quarter of 2026, this mix has shifted to 65% residential, with expanding contributions from commercial, manufacturing, and industrial work. This shift reflects a strategic pivot toward complex multi-trade work.
• Geographic Footprint: The company has expanded its footprint through the acquisition of A.L. Grading Contractors, LLC ("ALGC") on February 18, 2026. ALGC operates in Georgia, complementing Cardinal's core operations in North Carolina.
• Key Markets: As of December 31, 2025, the company held strong revenue presence in Raleigh ($463 million), Charlotte ($140 million), and Greensboro ($79 million). Charlotte operations specifically grew to approximately $94.1 million for the twelve months ended December 31, 2025.

Financial Evidence (as of May 2026):

• Backlog: The company reported a backlog of $854 million at the end of the quarter (Q1 2026), an all-time high. This backlog represents over 12 months of revenue at the current run rate.
• Revenue Recognition: As of March 31, 2026, the company expects to recognize $494.0 million within the next 12 months and the remaining $30 million in the period from 13 to 18 months.
• Guidance: Management increased full-year revenue guidance to a range of $675 million to $685 million (up from $665–$678 million) and adjusted EBITDA guidance to a midpoint of $680 million (up from $672 million).
• Margins: Management expects adjusted EBITDA margins to remain above 20% for the full year.
• Customer Concentration: The company is not overly dependent on a single client. The largest customer (Pulte Homes) represented 9.9% of revenue in 2025, and the top 10 customers represented 45.5% of revenue. Customer A comprised 13% of revenue in Q1 2026.
• New Markets: The company announced its first win in the mission-critical data center market, a $24 million contract to be self-performed with completion expected in 2027.

4. Archetype and Conviction

Archetype: Growth Leader / Margin Inflector The company fits the archetype of a Growth Leader with Margin Inflector characteristics. The evidence points to a company successfully scaling its operations through geographic expansion (Georgia acquisition) and market diversification (moving from 75% to 65% residential focus). The ability to maintain EBITDA margins above 20% while growing revenue and expanding into higher-complexity sectors (data centers, commercial) suggests a margin inflector profile.

Conviction Stack:

• Thesis Strength: Low (No named macro thesis; purely tactical).
• Evidence Quality: High. The evidence is robust, citing specific backlog figures ($854M), clear guidance raises, and detailed customer concentration data. The "12 months of revenue" in backlog provides high visibility.
• Structural Quality: Low/Unknown. The technical setup is undefined. The "Very High" ATR (6.2%) suggests the stock is volatile, which can be a double-edged sword for a growth story without a clear trend.
• Setup Readiness: None. No breakout or consolidation structure is present.
• Rerating Potential: Moderate to High, contingent on the successful integration of the ALGC acquisition and the realization of the data center contract. The backlog visibility supports a rerating if the market recognizes the quality of the earnings growth.

Valuation Context: While specific P/E or EV/EBITDA multiples are not provided in the evidence, the guidance raise and margin stability (>20%) suggest the market is pricing in a high-quality growth profile. The "Very High" ATR indicates the market is currently reacting with significant volatility, possibly due to the recent guidance raise or the acquisition news.

5. Invalidations, Strengths, and Gaps

What Would Strengthen the Case:

• Technical Breakout: A confirmed close above a defined resistance level (forming a "Confirmed-Active" coil) would validate the fundamental strength.
• Margin Expansion: Confirmation that the new commercial/data center mix is driving margins higher than the 20% baseline.
• Backlog Growth: Continued growth in the backlog beyond the $854 million level, indicating sustained demand.

What Would Invalidate the Case:

• Guidance Miss: A failure to meet the raised revenue or EBITDA guidance for the full year.
• Labor Constraints: Evidence that the "skilled labor shortage" mentioned in the thesis is actually constraining growth, leading to project delays or margin compression.

Gaps in Evidence:

• Technical Structure: There is no data on price action, volume, or moving averages to define a setup.
• Valuation Metrics: No P/E, P/S, or EV/EBITDA multiples are provided to assess relative value.
• Debt/Capital Structure: No information on the company's balance sheet, debt levels, or cash flow position is available in the provided evidence.
• Integration Risk: While the ALGC acquisition is noted, there is no specific data on the integration status or synergies realized to date.

PRIVATE ANALYST CALL

Judgment: Speculative Confidence: medium Key evidence: Backlog of $854 million represents over 12 months of revenue; Management raised full-year revenue guidance to $675-$685 million and EBITDA to $680 million; Successful expansion into commercial/data center markets with a $24 million contract win. Key risks: Very high ATR of 6.2% indicates elevated volatility and potential for sharp downside; No defined technical setup (Coil) exists to manage risk; Customer concentration remains a factor with top 10 customers representing 45.5% of revenue. Sizing hint: Position size should be reduced relative to a standard growth setup due to the lack of a defined entry point and high volatility. Expected path: Management expects to recognize $494 million in revenue within the next 12 months from the current backlog, with the data center contract completing in 2027. Expected horizon: 12 to 18 months for the backlog to convert to revenue. Failure mode to watch: A close below the current price level combined with a miss on the raised guidance, which would signal a breakdown in the growth narrative.
