• Kinder Morgan (NYSE:KMI) and Phillips 66 have launched a second open season for the Western Gateway Pipeline project.
• The project is designed to connect key refinery supply regions in the Midwest to Phoenix and major California fuel markets.
• The new open season focuses on expanded pipeline capacity and additional origin and destination points for shippers.

Kinder Morgan, trading at $28.58, sits in the midstream space with a long established footprint in North American energy infrastructure. The stock is up 3.8% over the past week, 6.3% over the past month, and 3.1% year to date, while showing a 3.1% decline over the past year. For investors, the Western Gateway news arrives against this mixed shorter term but stronger multi year share performance backdrop.

The second open season on Western Gateway indicates that Kinder Morgan is continuing to work to widen its reach between the Midwest, Phoenix, and California fuel markets. If the project advances as described, it could reshape how refined products move across the Western U.S., with implications for throughput volumes and returns on future invested capital. Investors will likely watch for commercial commitments, regulatory progress, and project timelines as key markers from here.

The Western Gateway partnership with Phillips 66 ties directly into Kinder Morgan’s core midstream role, giving it another route to move refined products from Midwest refineries into Phoenix and California. By using a mix of new-build pipe, reversals of existing Kinder Morgan and Phillips 66 lines, and joint tariffs into markets like Los Angeles and Las Vegas, the project is structured to improve route flexibility and use existing infrastructure where possible, which can matter for both capital intensity and future returns on invested capital.

Kinder Morgan narrative, refreshed by Western Gateway

Recent Q4 2025 results, with revenue of US$4.51b and net income of US$996m, alongside a 2% dividend increase to US$1.17 annualized, have reinforced a story of Kinder Morgan as a cash generating midstream operator that returns capital to shareholders. The Western Gateway open season sits on top of that, adding a potential growth leg in refined products alongside the company’s natural gas driven earnings profile that some analysts already view positively.

Risks and rewards around this pipeline expansion

• 🎁 Western Gateway taps high demand regions such as Phoenix, California and Las Vegas, which could support throughput once the system is in service.
• 🎁 Using reversals of existing SFPP and Gold Pipeline assets, rather than only greenfield miles, may help Kinder Morgan manage construction scope and timelines.
• ⚠️ Analysts have flagged that Kinder Morgan’s interest payments and dividend are not fully covered by earnings or free cash flows, so large projects can add pressure if returns fall short.
• ⚠️ The project still depends on final shipper commitments, regulatory processes and execution, which introduce timing and cost uncertainty.

What investors can watch next

From here, it is worth tracking how much of the remaining capacity is contracted in the second open season, how Kinder Morgan frames the capital spend and return expectations in future updates, and whether management commentary links Western Gateway to any change in dividend or capital allocation priorities.
