ITEM 2.Properties.

To manage the integrity and safety of our natural gas distribution and transmission systems, consistent with PHMSA regulations, we have integrity management programs that integrate information sources and data, identify risks to infrastructure integrity, rank risks, and designate measures and actions to reduce or mitigate risks as appropriate. These programs take into consideration numerous input factors and no single factor is determinative in our decision to take mitigative actions on our distribution or transmission pipeline systems. Based upon these programs, along with the oversight of state regulators responsible for adopting and enforcing the federal pipeline safety regulations, we believe that our distribution and transmission pipeline systems are suitable and adequate for our purposes.

Distribution, transmission, and related assets

In our distribution segment, we owned an aggregate of approximately 76,000 miles of underground distribution and transmission mains throughout our distribution systems. These mains are located on easements or rights-of-way. We maintain our mains through a program of continuous inspection and repair and believe that our system of mains is in good condition. Through our pipeline and storage segment we owned approximately 5,700 miles of gas transmission lines.

Storage Assets

We own underground gas storage facilities in several states to supplement the supply of natural gas in periods of peak demand. The following table summarizes certain information regarding our underground gas storage facilities at September 30, 2025:
