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.

Kirby’s Q2 Earnings Call: Our Top 5 Analyst Questions

KEX Cover Image

Kirby’s second quarter was marked by a steep negative market reaction, with shares dropping sharply after results were announced. Management pointed to a combination of resilient demand in the marine transportation segments and strength in power generation as drivers of quarterly performance. However, CEO David Grzebinski acknowledged operational headwinds, citing “navigational and lock delays” in the Inland Marine business and ongoing supply chain constraints in the Distribution and Services division. The company also highlighted that chemical market softness and macroeconomic uncertainty have started to affect customer activity, particularly in July, with Grzebinski stating, “Our chemical customers have been fighting a negative tape for at least the last year or so, but their volumes have held up.”

  • Adjusted EPS: $1.67 vs analyst estimates of $1.65 (1.2% beat)
  • Adjusted EBITDA: $199 million vs analyst estimates of $197.5 million (23.3% margin, 0.7% beat)

While we enjoy listening to the management's commentary, our favorite part of earnings calls are the analyst questions. Those are unscripted and can often highlight topics that management teams would rather avoid or topics where the answer is complicated. Here is what has caught our attention.

Our Top 5 Analyst Questions From Kirby’s Q2 Earnings Call

  • Reed Seay (Stephens Inc.) asked about the extent of demand softness in inland marine and spot pricing trends for July. CEO David Grzebinski explained that chemical market weakness has started to impact barge volumes but described the pullback as modest, with guidance assuming 90% utilization for Q3.

  • Seay (Stephens Inc.) also inquired about the drivers behind strong power generation results. Grzebinski said deliveries, not just down payments, fueled the quarter, and emphasized a growing backlog with continued robust orders from data centers.

  • Kenneth Scott Hoexter (Bank of America) pressed for clarity on why management shifted toward the lower end of guidance. Grzebinski said muted chemical demand was the key factor, but noted that only a slight demand improvement could boost earnings back toward the higher end.

  • Gregory Robert Lewis (BTIG, LLC) probed the rationale for deferring capital expenditures. CFO Raj Kumar explained that timing shifts in growth projects led to CapEx deferrals, which will increase free cash flow and enable more share buybacks if no acquisitions materialize.

  • Scott H. Group (Wolfe Research) asked about the sustainability of inland contract pricing and future margin potential. Grzebinski described Kirby’s pricing approach as “slow and steady” due to large sophisticated customers, and reiterated confidence that inland margins could eventually reach the high-20% range with gradual improvement.

Catalysts in Upcoming Quarters

Looking ahead, the StockStory team will be monitoring (1) whether inland marine spot pricing and barge utilization stabilize or deteriorate further in response to ongoing chemical market weakness, (2) the pace at which Kirby can convert its power generation backlog into revenue, especially as data center demand continues, and (3) the company’s ability to manage working capital and execute on capital allocation priorities, including share repurchases and potential acquisitions. Any significant changes in trade policy or supply chain conditions will also be key drivers of Kirby’s performance.

Kirby currently trades at $99.14, down from $120.08 just before the earnings. Is the company at an inflection point that warrants a buy or sell? See for yourself in our full research report (it’s free).
