For service-based businesses, 80% gross margins should be the absolute minimum. This high margin is not just for profit; it is the essential fuel required to cover all other business costs like sales, marketing, and administration, making it a prerequisite for scaling.

The logistics of servicing ATMs create a powerful local density advantage. Adding a new bank's ATM to an existing route has minimal extra cost, leading to extremely high incremental gross profit margins of 60-80% on new service contracts.

Contrary to expectations, AMT's traditional towers, often in less dense areas, have better profit margins than the Distributed Antenna Systems (DAS) required for urban cores. This economic reality has made peers' pivots to DAS underperform and has shaped AMT's own capital allocation strategy.

AMT's REIT designation, while tax-efficient, creates a structural dependency on debt. The requirement to distribute 90% of taxable income to shareholders starves the company of internal capital for reinvestment, forcing it to leverage its balance sheet to fund growth.

Investors and acquirers pay premiums for predictable revenue, which comes from retaining and upselling existing customers. This "expansion revenue" is a far greater value multiplier than simply acquiring new customers, a metric most founders wrongly prioritize.

AMT's advantage stems from owning irreplaceable land parcels optimized for cellular networks. Competitors face prohibitive zoning laws and degraded network quality if they build elsewhere, creating a massive barrier to entry similar to junkyard operator Copart.

Counterintuitively, consolidation among AMT's customers, like the T-Mobile/Sprint merger, is a primary driver of churn. The combined entity eliminates redundant towers to reduce costs, directly canceling lease agreements and creating multi-year revenue headwinds for AMT.

AMT's long-term incentive plan avoids common pitfalls by focusing 80% of its weighting on AFFO per share and average ROIC. This structure incentivizes management to prioritize profitable growth and capital efficiency, aligning their compensation directly with shareholder value creation.

A skilled service provider's pricing should target an 80% profit margin, with only 20% allocated to cost of goods. This high margin is not just profit; it's the capital engine that allows the business to fund expansion, such as hiring staff and renting space, without taking on external debt.
