About Cabling Installation & Maintenance:

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.

5 Revealing Analyst Questions From MDU Resources’s Q2 Earnings Call

MDU Cover Image

MDU Resources’ second quarter results were met with a negative market reaction, as investors responded to margin contraction and lower earnings compared to last year. Management attributed these outcomes to higher operating costs, unfavorable weather in its Natural Gas Distribution segment, and increased expenses related to planned maintenance. CEO Nicole Kivisto noted the impact of “warmer-than-normal temperatures” and “higher payroll-related costs,” particularly in the utility businesses. The company also cited increased operation and maintenance expenses across segments, which weighed on overall profitability.

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 MDU Resources’s Q2 Earnings Call

  • Ryan Michael Levine (Citi): Asked about the impact of a smaller storage project on the scale of the Bakken East pipeline. CEO Nicole Kivisto clarified that the projects are currently separate, though future synergies could arise if Bakken East advances, depending on customer commitments.
  • Ryan Michael Levine (Citi): Inquired whether the narrowed EPS guidance signals a shift in long-term growth targets. CFO Jason Vollmer responded that the revision reflects near-term weather and cost impacts, but does not indicate a change in the company’s multi-year EPS growth outlook.
  • Brian J. Russo (Jefferies): Sought clarity on how a potential state decision at the upcoming North Dakota Industrial Commission meeting could affect pipeline development plans. Kivisto said state support could help secure customer commitments, but the main focus remains on reaching binding agreements with customers.
  • Brian J. Russo (Jefferies): Asked for quantification of one-time versus ongoing drivers behind the updated guidance. Vollmer explained that weather effects are inherently unpredictable, while the planned maintenance outage was anticipated and not expected to recur.
  • Brian J. Russo (Jefferies): Queried how much excess capacity remains in the system before new infrastructure investments are needed for data centers. Kivisto indicated that some pockets of capacity remain, but larger loads may require new generation or transmission investments in the future.

Catalysts in Upcoming Quarters

In the coming quarters, the StockStory team will be monitoring (1) progress on regulatory approvals and rate cases in multiple states, (2) execution and customer uptake of major infrastructure projects like the Minot expansion and potential Bakken East pipeline, and (3) signs of sustained customer growth in the utility segment, especially related to new data center load. The company’s ability to manage operating costs and weather-driven volume swings will also be key to tracking its performance.
