Risks

• Ability to manage projects effectively and accurately estimate costs, especially for fixed-price contracts, including material changes in estimates for completion and recoverability of change orders.
• Market conditions, including rising or elevated levels of inflation or interest rates, regulatory or policy changes (e.g., permitting processes, tax incentives, government funding programs), access to capital, material and labor costs, supply chain issues, and technological developments, all of which may affect demand for services.
• Changes to governmental programs and spending policies, including the potential for reduced support for renewable energy projects as a result of the One Big Beautiful Bill Act (OBBBA), and changes in U.S. or foreign tax laws.
• Tariff and trade actions, including retaliatory trade actions, by the United States and/or other countries on U.S. exports or bans by foreign countries on certain of their exports, which could increase costs of key construction materials.
• Project delays due to permitting processes, compliance with environmental and other regulatory requirements, and challenges to the granting of project permits, which could cause increased costs and delayed or reduced revenue.
• The effect on demand for services of changes in the amount of capital expenditures by customers due to, among other things, economic conditions, inflationary issues, availability and cost of financing, supply chain disruptions, climate-related matters, and customer consolidation.
• Activity in the industries served and the impact on customer expenditure levels of fluctuations in commodity prices (including fuel and energy), material, labor, supplies, or equipment costs, and/or supply-related issues.
• Risks related to completed or potential acquisitions, including the ability to integrate acquired businesses within expected timeframes, achieve projected revenue/cost savings, and the risk of potential asset impairment charges and write-downs of goodwill.
• Ability to attract and retain qualified personnel, key management, and skilled employees, and to maintain a workforce based upon current and anticipated workloads.
• Any material changes in estimates for legal costs or case settlements or adverse determinations on any claim, lawsuit, or proceeding.
• The adequacy of insurance, legal, and other reserves, particularly concerning adverse climate and weather events like wildfires that increase operational and legal risks.
• The highly competitive nature of the industry and the ability of customers to terminate or reduce work, or prices paid for services, on short or no notice under contracts, and/or customer disputes.
• The effect of regulatory initiatives, including risks related to and the costs of compliance with existing and potential future sustainability requirements, including with respect to climate-related matters.
• Systems and information technology interruptions and/or data security breaches that could adversely affect operations, operating results, data security, or reputation, intensified by the rapid evolution of AI technologies.
• Dependence on a limited number of customers (AT&T represented 10% of consolidated revenue in 2025) and the ability to replace non-recurring projects.
• Risks associated with operating in or expanding into additional international markets, including increased tariffs, foreign currency fluctuations, and compliance with anti-bribery laws (e.g., FCPA).
• Risks related to operations that employ a unionized workforce, including labor availability, productivity, relations, and multiemployer union pension plans (underfunding and withdrawal liabilities).
• A failure of internal control over financial reporting could materially affect the business, especially with acquired businesses.
• A small number of existing shareholders having the ability to influence major corporate decisions.
• Anti-takeover provisions in articles of incorporation and Florida law that may make it more difficult to effect a change in control.
• Additional tax liabilities associated with operations due to dynamic tax laws and inherent uncertainty in quantifying income tax positions.

Future Outlook

The company anticipates a broad, multi-year investment cycle in U.S. communications, energy, and infrastructure systems, driven by continued demand for fiber network expansion, wireless densification, broadband deployment, renewable generation facilities, data center and industrial projects, and civil infrastructure. It is positioned to support increasing requirements for transmission and distribution system expansion, reliability, resiliency, grid hardening, and modernization, as well as continued investment in natural gas, water/wastewater, carbon capture, and hydrogen infrastructure. The company forecasts 2026 capital expenditures of approximately $270 million ($200 million net of asset disposals) and $230 million to $255 million in equipment purchases under finance leases. It expects to collect substantially all outstanding accounts receivable balances within the next twelve months and believes its financial position, cash flows, and operational strengths will be sufficient to meet liquidity needs for the foreseeable future, remaining in compliance with debt covenants.

Industry Context

StockSavvy.ai notes that MasTec's strong performance in Communications and Clean Energy aligns with broader industry trends of accelerating data consumption, AI deployment, increasing electrification, and the transition to low-carbon and renewable energy sources. The company is strategically positioned to capitalize on the multi-year investment cycle in U.S. infrastructure, driven by both technological advancements and significant federal funding programs like the IIJA and IRA. The flat performance in Pipeline Infrastructure, however, contrasts with the broader industry's projected robust demand for natural gas pipelines driven by LNG exports and data centers, suggesting potential underperformance or specific project challenges in this segment. The impact of the OBBBA on clean energy tax credits introduces a new layer of regulatory uncertainty that could shift investment priorities within the energy sector.

Comparison to Industry Standards

• MasTec's 5-year cumulative total return (December 31, 2020 to December 31, 2025) was $318.82 (starting from $100), significantly outperforming the S&P 500's cumulative total return of $196.16 for the same period.
• MasTec's performance lagged its 2025 Peer Group (Quanta Services, Inc., MYR Group, Inc., Dycom Industries, Inc., Primoris Services Corporation), which saw a higher cumulative total return of $540.62 for the same period, suggesting peers may be capturing a larger share of market growth or operating with higher efficiency.
