Activist investor Starboard Value has taken a stake in Knife River, a U.S. construction-materials company, and is pushing management to improve profit margins or explore a sale, according to a report in The Wall Street Journal.
The move adds another name to a growing list of activist campaigns targeting companies that have underperformed since being spun off from larger parents. Starboard, known for taking sizable positions in companies it believes are undervalued, is focusing on Knife River's profitability, which has lagged behind peers since the company became independent.
What's going on here?
Knife River was spun off from MDU Resources in 2023, a move that was supposed to unlock value by letting each business focus on its own operations. But Starboard argues the breakup hasn't translated into meaningfully better profitability. The firm's core ask, per the WSJ, is to close the gap between Knife River's adjusted EBITDA margin—a profit measure before interest, taxes, depreciation, and amortization—and those of its closest competitors.
EBITDA margins are a common way to compare how efficiently companies turn revenue into profit, stripping out the effects of financing and accounting decisions. A wide gap suggests a company is leaving money on the table, either through higher costs, weaker pricing power, or operational inefficiencies.
Starboard's playbook often involves pushing for operational improvements, management changes, or, if those don't materialize, a sale of the company. In this case, the activist is reportedly open to both outcomes: fix the margins or find a buyer.
Why does this matter?
Knife River operates in a cyclical industry tied to construction and infrastructure spending. Demand for its aggregates, ready-mix concrete, and asphalt can swing with the economy and government spending. That makes margin performance especially important—when volumes dip, companies with fat margins can still generate healthy cash flow, while thinner-margin operators feel the pinch.
The company's stock has likely been a target for Starboard because of the valuation gap. If Knife River can improve its margins to match peers, the share price could rise significantly. Alternatively, a sale could deliver an immediate premium to shareholders.
For everyday investors, this news is a reminder that spin-offs don't always deliver the promised benefits. While the logic of separating businesses can be sound, execution matters. A company that was once part of a conglomerate may lack the focus, cost discipline, or management incentives to thrive on its own.
What it means for investors
If you own Knife River shares, this development could be positive. Activist involvement often leads to changes that boost shareholder value, whether through operational improvements, cost cuts, or a sale. However, it also introduces uncertainty. Management may resist the activist's demands, leading to a proxy fight or prolonged public dispute.
For those watching from the sidelines, the story highlights the broader trend of activist investors targeting mid-cap companies with lagging margins. Similar campaigns have popped up across sectors, from energy producers like Devon Energy to furniture maker Ethan Allen. The pattern is often the same: identify a company with a clear profitability gap, build a stake, and push for change.
Investors should also note that Knife River's situation is not unique. Many companies that go through spin-offs or other corporate restructurings struggle to hit their financial targets in the first few years. The market often prices in improvement, and when it doesn't come, activists step in.
What happens next will depend on how Knife River's board responds. If they engage constructively, we could see a strategic review, cost-cutting initiatives, or even a formal sale process. If they resist, the fight could escalate, potentially leading to a proxy contest or a public campaign to replace directors.
For now, the key metric to watch is Knife River's adjusted EBITDA margin. If it starts to close the gap with peers, the pressure may ease. If it doesn't, the likelihood of a sale increases.
As always, this is not a recommendation to buy or sell. But for investors in the company, it's worth paying attention to how this plays out. Activist campaigns can be a catalyst for change, but they can also be messy and unpredictable.
