The essentials

  • Return on invested capital of ~34% TTM, well above the 10% bar, with positive working capital and virtually no debt.
  • TTM growth of 12.5% includes a pricing component of ~290bp tied to tariffs that will likely normalize toward a path of ~6-9% annually.
  • The current price (33× operating income) trades well above the ceiling of the archetype band (18×), implying multiple compression in all three modeled scenarios.

Total return at 5 years: -3.7%/year = -6.8% appreciation + 3.1% dividend. The target price ($36) is ex-dividend; the $7 in dividends collected over 5 years are added separately.

By both methods, the value today (DCF $34 · Multiples $35) is below the market price ($51).

Pillars of the analysis

The verdict — today vs 5 years

Today — expensive, no margin of safety: at $51 trades ~46.9% above its value discounted to today (~$35); the expected return does not even reach the risk-free rate (4.5%).

At 5 years — Sobrevalorado: the expected total return is negative — the price already discounts a demanding scenario that, if not met, results in a loss.

The bridge: the return at 5 years falls below the risk-free rate (4.5%) — which is why there is not even a discount to today's value. To require a 15% annual return, it would need to be bought at ~$22.

Thesis

The business

Fastenal is an MRO industrial distributor of exceptional quality: return on invested capital of ~34% TTM, no material financial leverage, with a narrow, stable moat sustained by logistics scale and switching costs from customer-site managed inventory (FMI). Recent growth (12.5% TTM) includes an elevated tariff-linked pricing component that will likely normalize toward a more moderate path.

The valuation

Valued at the enterprise level on EV/EBIT over operating income, with an exit multiple of 15.7× within the industrial and maintenance distribution archetype band (14×-18×), reflecting the business's exceptional quality and its stable moat. The 5-year value in the base case is $36 per share.

The margin of safety

No margin of safety: the price already discounts a demanding scenario. The current price trades at 33× trailing-twelve-month operating income, well above the ceiling of the archetype band (18×), implying multiple compression under any of the three modeled scenarios, including the favorable one.

What to watch

The key disconfirmer is whether the deceleration of the tariff-linked pricing contribution (~290bp in the second quarter of 2026) is offset by a sustained pace of share gains in high-spend sites and Digital Footprint penetration; if not, growth converges faster toward the adverse scenario.
