ANALYST NOTE: CTOS (Custom Truck One Source, Inc.) Date: 2026-06-13 Analyst: StoryStocks-Native Equity Analyst

1. Structural Readiness

Current State: Confirmed (Active) Conservative Entry: $6.87 Breakout Level: $6.87 (The breakout fired at this level, establishing the new structural baseline). Current Price: $11.27 Extension: +64.0% vs. conservative entry.

2. The Thesis Layer

Primary Secular Theme: Energy Transition & Electrification → Grid & Transmission Modernization. Directness: Tier Direct. Confidence: High.

CTOS is positioned as a direct beneficiary of the massive capital expenditure cycle required to modernize the North American power grid. The company's core equipment (bucket trucks, digger derricks, cranes) is essential for the physical construction and maintenance of transmission and distribution (T&D) infrastructure. The thesis is reinforced by the "Energy Transition & Electrification" theme, specifically the need to upgrade aging infrastructure to handle increased load from data centers and renewable integration. The company is not merely a peripheral player; its revenue is directly tied to the volume of T&D utility work, which management cites as operating at "record levels."

3. The Business

Business Model & Industry: CTOS operates as a specialty equipment provider in North America, serving the electric utility (T&D), telecommunications, rail, forestry, and waste management sectors. The business is structured into three primary segments:

• Equipment Rental Solutions: Renting new and pre-owned specialized machinery.
• Truck and Equipment Sales: Selling new, customized equipment.
• Aftermarket Parts and Services: Providing maintenance, repair, and parts.

Operational Evidence (as of 2026-06-13):

• Backlog Strength: As of Q1 2026, the sales order backlog stood at $411.3 million, a 23% increase from the prior quarter's end. Management confirmed in the Q1 2026 earnings transcript (2026-04-28) that the backlog "has continued to grow so far in Q2."
• Revenue Growth: Total revenue for the three months ended March 31, 2026, was $461.6 million, up 9.3% year-over-year. This growth was driven by a 3.7% increase in rental fleet utilization and an 11.8% increase in the average "On-Rent Equipment Cost" (OEC) per unit, alongside strong new equipment sales.
• Guidance: Management is affirming full-year 2026 revenue guidance of $2.005 billion to $2.12 billion. Crucially, they raised adjusted EBITDA guidance to a range of $415 million to $440 million, citing "strong conditions in the T&D end markets."
• Capital Allocation: For 2026, the company expects to grow its rental fleet based on net OEC by mid-single digits, with a planned net investment of $150 million to $170 million. This represents a meaningful reduction from the $250 million investment in 2025, suggesting improved capital efficiency or a shift toward higher-yield assets.
• Market Dynamics: The company serves approximately 8,000 customers, with a diversified base where the top 15 customers represent only 23.6% of revenue, mitigating single-customer concentration risk.

4. Archetype and Conviction

Archetype: Growth Leader / Cyclical Recovery (Structural). CTOS fits the profile of a Growth Leader operating within a secular cyclical upswing. The company is not a deep value recovery play; it is a high-quality compounder benefiting from a multi-year infrastructure build-out.

Conviction Stack:

• Thesis Strength: High. The "Energy Transition" theme is not a speculative narrative but a funded reality, with over 75% of Infrastructure Act funds allocated as of late 2025 and data center demand projected to grow 165% by 2035.
• Evidence Quality: Strong. The evidence base is robust, featuring specific backlog numbers, raised EBITDA guidance, and clear operational metrics (utilization, OEC) from both earnings transcripts and SEC filings dated April 2026.
• Structural Quality: The ATR of 4.0% places the stock in the "productive" bucket (historical sweet spot 4–6%), indicating healthy trend-following volatility without the erratic behavior of extreme volatility stocks.
• Rerating Potential: The combination of rising EBITDA margins (guidance raised) and a secular tailwind suggests the market may re-rate the stock from a cyclical equipment provider to a structural growth play in grid infrastructure.

5. Invalidation, Strengthening, and Gaps

Invalidation Triggers:

• A significant contraction in the sales order backlog (e.g., a drop below $350 million) or a failure to meet the raised EBITDA guidance range ($415M–$440M) would signal a breakdown in the thesis.
• A sharp decline in rental utilization rates below the 3.7% growth seen in Q1 2026.

Strengthening Factors:

• Continued growth in the Q2 backlog beyond the Q1 levels.
• Further expansion of the third-party service capacity initiative (launched in 2026) leading to margin expansion.
• Confirmation of the "record levels" of demand in T&D utility markets in subsequent quarterly reports.

Evidence Gaps:

• Missing Evidence: There is no specific evidence in the provided dataset regarding the *geographic* breakdown of the backlog growth or the specific mix of new vs. used equipment sales for the full year 2026.
• Missing Evidence: No data is provided on the specific impact of the "Infrastructure Act" spending pace on CTOS's specific order intake, other than the general statement that funds are allocated.
• Missing Evidence: No explicit guidance on the *long-term* (post-2026) revenue trajectory beyond the current fiscal year, though management cites secular megatrends.

PRIVATE ANALYST CALL

Judgment: Buy Confidence: High Sizing hint: Position size should reflect the high conviction in the secular thesis and the confirmed structural setup, utilizing the 4.0% ATR for volatility-based sizing. Expected path: Management expects continued backlog growth and mid-single digit fleet expansion; the company is positioned to capture the secular build-out of the grid, likely sustaining revenue and margin expansion through 2026 and beyond. Expected horizon: 12 to 24 months, aligned with the multi-year infrastructure build-out cycle and the current fiscal year guidance. Failure mode to watch: A sustained drop in rental utilization rates or a contraction in the sales order backlog below $350 million.
