Why Is HESS MIDSTREAM LP A (HESM) Stock Down Today?

Hess Midstream LP A (HESM) fell 15.56% to $32.67 in Monday trading, marking one of the largest declines in its recent history. The sharp drop came after Chevron announced a restructuring of its stake in Hess Midstream, which included a $200 million cash payment and a planned Bakken extension through 2045. The move also led to a revised 2027 EBITDA outlook that is significantly lower than prior projections.

What Happened

Chevron is set to divest its ownership interests in Hess Midstream and the DJ Basin Crude Midstream Assets. The revised agreements are expected to reduce Bakken unit midstream costs by about 50% but include a $200 million cash transfer to Chevron. These changes signal a structural shift in Hess Midstream’s business model and long-term profitability. The company now expects 2026 adjusted EBITDA of $1.225 billion to $1.25 billion but has revised its 2027 outlook to a range of $850 million to $950 million. This is a notable decline from earlier estimates of $1.225 billion to $1.25 billion for the same period. The market reacted swiftly, with the stock opening at a 1.8% gap down and falling further throughout the session.

What The Data Shows

The stock opened at $38.01 and fell to a session low of $32.22, with volume reaching 3.5 million shares, 2.9 times the 3-month average. The stock has traded within a 52-week range of $31.63 to $41.44, and on Monday alone, it printed 10 fresh 52-week lows. The company reported a net margin of 23.2% and a dividend yield of 8.21%, but the market appears to be pricing in lower future earnings and cash flow. The adjusted EBITDA margin is expected to remain strong at 75%, but the reduced 2027 outlook has clearly dented investor confidence.

What To Watch

Investors should monitor the company’s Q3 and Q4 2026 results, which include a target of 5% annual distribution growth per Class A share. Coverage breadth and analyst reactions will also be key indicators of how the market digests the new business structure.
