F5 (FFIV) Q1 CY2025 Highlights:
Company Overview
Initially started as a hardware appliances company in the late 1990s, F5 (NASDAQ:FFIV) makes software that helps large enterprises ensure their web applications are always available by distributing network traffic and protecting them from cyberattacks.
Sales Growth
A company’s long-term sales performance can indicate its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Unfortunately, F5’s 3.5% annualized revenue growth over the last three years was weak. This was below our standard for the software sector and is a rough starting point for our analysis.

This quarter, F5 reported year-on-year revenue growth of 7.3%, and its $731.1 million of revenue exceeded Wall Street’s estimates by 1.7%. Company management is currently guiding for a 7.8% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 3.4% over the next 12 months, similar to its three-year rate. This projection doesn't excite us and implies its newer products and services will not catalyze better top-line performance yet.

Billings
Billings is a non-GAAP metric that is often called “cash revenue” because it shows how much money the company has collected from customers in a certain period. This is different from revenue, which must be recognized in pieces over the length of a contract.
F5’s billings came in at $707.5 million in Q1, and over the last four quarters, its growth was underwhelming as it averaged 8.7% year-on-year increases. However, this alternate topline metric grew faster than total sales, meaning the company collects cash upfront and then recognizes the revenue over the length of its contracts - a boost for its liquidity and future revenue prospects.

Customer Acquisition Efficiency
The customer acquisition cost (CAC) payback period represents the months required to recover the cost of acquiring a new customer. Essentially, it’s the break-even point for sales and marketing investments. A shorter CAC payback period is ideal, as it implies better returns on investment and business scalability.
F5 is very efficient at acquiring new customers, and its CAC payback period checked in at 22.3 months this quarter. The company’s rapid recovery of its customer acquisition costs means it can attempt to spur growth by increasing its sales and marketing investments.
