AI Analysis

AI-generated, general educational analysis — not personal investment advice.

I approach MasTec as a Graham-style value investor, and the first question is price versus proven earning power. At the close on 2026-10-13, the shares were $206.12, giving a market value of $16.6B. The business is a $14.3B-revenue infrastructure contractor in fiscal 2025, with 37,000 employees and five segments spanning communications, clean energy, power delivery, pipelines, and other infrastructure. That is real scale, but construction is project-based and cyclical; the moat is limited to relationships, specialized labor, and execution rather than a durable pricing franchise. The recovery is genuine. In fiscal 2025, revenue was $14.3B, net income $399.0M, and diluted EPS $5.07, versus fiscal 2024, revenue $12.3B, net income $162.8M, and EPS $2.06, and a fiscal 2023, net loss of $49.9M and EPS -$0.64. In fiscal Q2 2026, the quarter ended 2026-06-30, revenue was $4.4B, net income $130.1M, and diluted EPS $1.65. FairStock classifies it as a TURNAROUND because it returned to profit after a loss within the last three years. Still, the financials are not fortress-like. The FairStock calculation shows debt-to-equity of 0.90, ROCE of 5.28%, Altman Z of 2.35, and trailing free cash flow of $244.8M, only a 1.5% FCF yield. The Q2 2026 net margin was 2.98%, so small cost overruns matter. Valuation is the rub: the FairStock P/E is 32.82, P/B is 4.63, and the Graham Number is $78.81, leaving the price far above asset-based value. PEG of 0.63 offers some growth-adjusted comfort, but I would want a wider margin of safety and stronger cash generation before calling this a classic value bargain.

In plain English: MasTec builds and maintains big infrastructure projects such as communication networks, power lines, pipelines, and clean energy facilities. The company has swung back to profit and its sales and earnings are growing, but profit margins are thin and it uses a fair amount of debt. At $206.12 a share, the price looks high compared with the company’s accounting value and cash flow, even though it may look less demanding relative to its earnings growth.
