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.

Why Myriad Genetics (MYGN) Stock Is Down Today

MYGN Cover Image

What Happened?

Shares of genetic testing company Myriad Genetics (NASDAQ: MYGN) fell 36% in the afternoon session after the company reported mixed first quarter 2025 results: it lowered its full-year revenue, EPS, and EBITDA guidance due to weaker trends in its pharmacogenomics and hereditary cancer testing (women's health) businesses. On the other hand, MYGN significantly beat analysts' EPS and EBITDA expectations. Overall, this was a softer quarter.

What The Market Is Telling Us

Myriad Genetics’s shares are very volatile and have had 22 moves greater than 5% over the last year. But moves this big are rare even for Myriad Genetics and indicate this news significantly impacted the market’s perception of the business.

The biggest move we wrote about over the last year was 2 months ago when the stock dropped 16.1% on the news that the company reported a tough quarter(Q4 2024), with revenue missing expectations and 2025 guidance for both revenue and EBITDA coming in light. While revenue did grow 7% compared to the previous year, thanks to strong gains in Pharmacogenomics (+14%y/y) and Prenatal testing (+12%y/y), it wasn't enough to make up for weakness in other areas, leading to the overall shortfall. 

Despite the revenue miss, Myriad Genetics delivered a strong adjusted EBITDA, significantly outpacing analysts' expectations. The company benefited from improved gross margins, driven by higher revenue per test and operational efficiencies. 

Looking ahead, the company provided 2025 revenue guidance of $850 million at the midpoint, which implies slower growth compared to 2024. Adjusted EBITDA guidance also fell short of expectations, raising concerns about profitability. Adding to the challenges, UnitedHealthcare's decision to cut coverage for certain multi-gene pharmacogenetic tests in 2025 poses a headwind for the GeneSight business. 

On the leadership front, COO Sam Raha was expected to take over as CEO in April 2025, replacing Paul Diaz. 

Overall, it wasn't a great quarter as revenue growth didn't meet expectations, guidance left investors uncertain, and upcoming reimbursement changes add further risk.

Myriad Genetics is down 67.1% since the beginning of the year, and at $4.44 per share, it is trading 84.5% below its 52-week high of $28.60 from September 2024. Investors who bought $1,000 worth of Myriad Genetics’s shares 5 years ago would now be looking at an investment worth $297.79.
