Company Snapshot

Flowserve designs, manufactures, and services industrial flow management equipment with a presence in the United States, Europe, the Middle East, Africa, Asia, and internationally, offering a range of flow control products. The company generates revenue through the sale of engineered flow control products and aftermarket services, with a focus on both new equipment and recurring maintenance contracts. It serves customers in oil and gas, chemical and pharmaceutical, power generation, water management, and a range of general industrial markets worldwide.

Foolish Take

Even after a strong run over the past year, Flowserve’s renewed momentum — and this step-up in institutional conviction behind it — matters for long-term investors. The stock is nearing all-time highs, and the latest quarter showed the kind of operational consistency that tends to support durable reratings: expanding margins, rising cash generation, and a business mix increasingly skewed toward higher-quality aftermarket revenue.

Flowserve’s third-quarter results underscored that strength. Sales rose 3.6% year over year to $1.2 billion, while adjusted operating margin jumped 370 basis points to 14.8%. Adjusted EPS climbed to $0.90, up 45% from last year. Bookings topped $1.2 billion, including 6% aftermarket growth—an important signal of recurring demand.

For a fund like D1, Flowserve’s accelerating profitability and backlog strength are a fitting profile. And as evidence, the position now makes up 4.6% of its equity book, placing it alongside higher-growth names like Reddit and Clean Harbors.
