Fastenal Co

FAST

Fastenal began as an industrial retailer, expanding its product portfolio from nuts and bolts to cutting tools, safety equipment, and janitorial supplies. It transitioned into a distributor by building out a dense network of branches close to its business customers. Once a customer becomes large enough, Fastenal installs vending machines and its own personnel on-site. Today, these on-site locations exceed Fastenal's branch count and remain the firm's main focus for expansion. Fastenal acts as a one-stop outsourcing partner for its industrial customers, offering value-added services along with a wide breadth of maintenance, repair, and operations supplies.

NetFlix Inc

NFLX

Netflix's relatively simple business model involves only one business, its streaming service. It has the biggest television entertainment subscriber base in both the United States and the collective international market, with more than 300 million subscribers globally. Netflix has exposure to nearly the entire global population outside of China. The firm has traditionally avoided a regular slate of live programming or sports content, instead focusing on on-demand access to episodic television, movies, and documentaries. The firm introduced ad-supported subscription plans in 2022, giving the firm exposure to the advertising market in addition to the subscription fees that have historically accounted for nearly all its revenue.
