About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Carvana (CVNA): Buy, Sell, or Hold Post Q1 Earnings?

CVNA Cover Image

Since June 2020, the S&P 500 has delivered a total return of 83.5%. But one standout stock has more than doubled the market - over the past five years, Carvana has surged 201% to $342.50 per share. Its momentum hasn’t stopped as it’s also gained 36.3% in the last six months thanks to its solid quarterly results, beating the S&P by 38.8%.

Is now still a good time to buy CVNA? Or is this a case of a company fueled by heightened investor enthusiasm? Find out in our full research report, it’s free.

Why Does Carvana Spark Debate?

Known for its glass tower car vending machines, Carvana (NYSE: CVNA) provides a convenient automotive shopping experience by offering an online platform for buying and selling used cars.

Two Positive Attributes:

1. Retail Units Sold Skyrocket, Fueling Growth Opportunities

As an online retailer, Carvana generates revenue growth by expanding its number of users and the average order size in dollars.

Over the last two years, Carvana’s retail units sold, a key performance metric for the company, increased by 13.8% annually to 133,898 in the latest quarter. This growth rate is among the fastest of any consumer internet business and indicates its offerings have significant traction.

2. Increasing Free Cash Flow Margin Juices Financials

Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.

As you can see below, Carvana’s margin expanded by 30.2 percentage points over the last few years. This is encouraging, and we can see it became a less capital-intensive business because its free cash flow profitability rose more than its operating profitability. Carvana’s free cash flow margin for the trailing 12 months was 6.4%.

One Reason to be Careful:

Customer Spending Stalls, Engagement Falling?

Average revenue per unit (ARPU) is a critical metric to track because it measures how much customers spend per order.

Carvana’s ARPU has been roughly flat over the last two years. This isn’t great, but the increase in retail units sold is more relevant for assessing long-term business potential. We’ll monitor the situation closely; if Carvana tries boosting ARPU by taking a more aggressive approach to monetization, it’s unclear whether units can continue growing at the current pace.

Final Judgment

Carvana’s positive characteristics outweigh the negatives, and with its shares beating the market recently, the stock trades at 24× forward EV/EBITDA (or $342.50 per share). Is now a good time to initiate a position? See for yourself in our full research report, it’s free.
