## Overview
Activist investor Starboard Value has built a significant stake in Flowserve Corp., an industrial pump and flow-control equipment maker, and is engaging with the company about potential changes, according to people familiar with the matter (Bloomberg, April 27).
## Details
The stake-building was reported by Bloomberg, citing people familiar with the matter, indicating discussions are underway between Starboard and Flowserve regarding possible strategic, operational, or governance changes (Bloomberg, April 27). Specific demands or the size of the stake were not disclosed in initial reporting.
## Why It Matters
Starboard Value is a well-known activist investor with a track record of pushing for operational overhauls, board changes, and sometimes breakups or sales at industrial and technology companies. A new campaign at Flowserve could signal upcoming shareholder pressure campaigns, management changes, or strategic alternatives (divestitures, M&A) at the company. For attorneys and dealmakers, activist campaigns like this often generate proxy fights, litigation, and advisory work, and are worth tracking as the situation develops.
## Developments to Watch
- Whether Starboard formally discloses its stake via SEC filing (13D)
- Specific demands: board seats, cost cuts, strategic review, or sale
- Flowserve's response and any settlement or proxy contest
- Peer industrial company activist activity given trend of activist interest in industrials
