Company Overview

Founded in 2000 as a business unit within MicroStrategy, Alarm.com (NASDAQ: ALRM) is a software-as-a-service platform that enables users to control their security systems and smart home appliances from a single app.

Revenue Growth

A company’s long-term sales performance is one signal of its overall quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Regrettably, Alarm.com’s sales grew at a weak 6.6% compounded annual growth rate over the last three years. This was below our standard for the software sector and is a rough starting point for our analysis.

This quarter, Alarm.com reported year-on-year revenue growth of 8.8%, and its $254.3 million of revenue exceeded Wall Street’s estimates by 4.3%.

Looking ahead, sell-side analysts expect revenue to grow 3.2% over the next 12 months, a deceleration versus the last three years. This projection is underwhelming and implies its products and services will face some demand challenges.

Software is eating the world and there is virtually no industry left that has been untouched by it. That drives increasing demand for tools helping software developers do their jobs, whether it be monitoring critical cloud infrastructure, integrating audio and video functionality, or ensuring smooth content streaming.

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.

Alarm.com is extremely efficient at acquiring new customers, and its CAC payback period checked in at 14.6 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.
