Knife River Reiterates Focus on Disciplined Execution and Shareholder Value Creation
Knife River issued a statement responding to a letter from activist investor Starboard Value, whose investment the company first learned of on September 22, 2026.
The Board said it welcomes shareholder input and will engage with Starboard, while reaffirming confidence in its EDGE strategy and vertically integrated construction materials platform.
No specific demands or strategic changes were disclosed; the activist stake itself is a potential catalyst for value-unlocking actions.

Starboard Delivers Letter to Knife River
Starboard Value LP, a Knife River stockholder, delivered a public letter to CEO Brian Gray and the board criticizing the company's failure to deliver promised margin improvement.
Starboard outlined a path to 22% adjusted EBITDA margins by FY2029 through improved aggregates pricing and cost reductions, and urged the company to evaluate strategic alternatives given the scarcity value of its assets.
The letter escalates activist pressure and raises the prospect of strategic review or board changes at Knife River.

Knife River Corporation furnished a September 2026 investor presentation via an 8-K Item 7.01 filing dated September 23, 2026, signed by CFO Nathan W. Ring.
The presentation discloses that second-quarter 2026 headwinds continue into the seasonally busiest period, citing approximately $8M of adjusted EBITDA impact from higher fuel costs, roughly $10M from weather and delayed Texas/Hawaii jobs, and about $6M from fewer public bid lettings driving increased competition.
Management expects second-half 2026 contracting services margins of approximately 9 to 10% and notes diesel prices rose around 40% since early July. Longer term, the company highlights its vertically integrated aggregates strategy, 100 acquisitions since 1992, and growth drivers including data centers, semiconductor facilities, and unspent IIJA infrastructure funding.

Knife River Corporation (KNF) Q2 2026 Earnings Call Transcript
seekingalpha.com • 2mo ago SEC Filing ⚠ 8
KNF: 10-Q · periodic report
Knife River grew second-quarter 2026 revenue 13% year over year to $938.6 million on double-digit volume gains in aggregates, ready-mix concrete and asphalt, but net income fell 13% to $43.9 million, or $0.77 per diluted share versus $0.89 a year ago, as competitive bidding compressed contracting services gross margin to 7.6% from 12.0%.
The first half swung to a wider net loss of $35.3 million from $18.1 million, though Adjusted EBITDA rose 5% to $107.9 million on 14% revenue growth, and management noted that expected margins on its $1.22 billion contracting backlog are slightly lower than a year ago.
Leverage increased: a May 2026 amendment added $400 million to the Term Loan B, bringing it to $895 million outstanding and total long-term debt to roughly $1.62 billion, while the company spent $184.4 million on four first-half acquisitions, including its entry into Utah via Morgan Asphalt.
New legal exposure surfaced in July 2026 when three lawsuits were filed in Multnomah County, Oregon alleging elevated metals in well water caused by mining at the company's Woodward Site near Prineville; Knife River says it will vigorously defend the actions and cannot yet estimate any potential loss.

Knife River Corporation Reports Second Quarter 2026 Financial Results
Knife River delivered Q2 revenue of $938.6 million, a 13% increase year-over-year, driven by 20% growth in contracting services and double-digit volume gains in material product lines.
The company raised its full-year 2026 guidance, projecting revenue between $3.4 billion and $3.6 billion and Adjusted EBITDA between $520 million and $560 million, supported by a sequentially increased backlog of $1.2 billion.
Despite the top-line growth, net income fell 13% to $43.9 million due to energy cost headwinds and tough comparisons against prior-year asset sale gains, though Adjusted EBITDA remained relatively stable at $139.7 million.
