At the same time, an investor letter from Harbor Capital Advisors drew attention to ongoing weakness in NewMarket’s petroleum additives business, a core revenue contributor that is shaping investor sentiment.

What Is NewMarket’s Investment Narrative?

To own NewMarket today, you have to be comfortable owning a mature chemicals business whose fortunes are still tied closely to its petroleum additives segment, even as that segment has recently weighed on results and sentiment. The Q4 and full‑year 2025 figures showed softer sales and earnings, so the key short‑term catalyst is whether management can stabilize profitability in additives while maintaining pricing and customer relationships. The board’s decision to reaffirm the US$3.00 quarterly dividend, despite that earnings pressure, sends a steadying signal but does not fundamentally change the near‑term drivers. Likewise, adding long‑time insider Bruce Hazelgrove to the board and elevating Susan Ridlehoover as Principal Accounting Officer look more like continuity moves than game‑changers. The biggest risk remains prolonged weakness in petroleum additives against a backdrop of high debt.

However, there is one business concentration risk here that investors should not overlook.
