Donaldson Company, a global leader in technology-led filtration products, closed its fiscal year on a strong note amid a backdrop of tariffs, Middle East conflict, and uneven industrial demand. The quarter marked the first reporting period including Facet Filtration, the largest acquisition in the company's history, which expanded its aerospace and defense and power-generation businesses. For investors, the report matters because it tests whether Donaldson can sustain margin expansion while integrating a major deal and navigating cost inflation. Strong aftermarket sales and record operating margin signaled resilience, while the fiscal 2027 outlook provides the first full-year view of how the Facet integration will shape earnings.
For the fourth quarter of fiscal 2026, ended July 31, 2026, Donaldson reported net sales of $1.0588 billion, an 8.0% increase from $980.7 million a year earlier and ahead of consensus estimates near $1.04 billion. GAAP (Generally Accepted Accounting Principles) net earnings were $129.3 million, up from $114.3 million, with GAAP diluted EPS of $1.10 compared with $0.97 in the prior-year quarter. On an adjusted basis, EPS rose 12% to $1.15, exceeding the roughly $1.12 analysts had expected.
Gross margin expanded 180 basis points to 36.3%, and adjusted operating margin reached an all-time high of 17.5%, up 110 basis points year over year. For the full year, sales increased 5% to $3.8856 billion, GAAP diluted EPS climbed 26.2% to $3.85, and adjusted EPS rose 8% to $3.98. By segment, Mobile Solutions sales rose 8% to $635 million, Industrial Solutions increased 8% to $334 million, and Life Sciences grew 10% to $90 million.

Donaldson's fourth-quarter results came in ahead of expectations, with management highlighting that the company "delivered fourth quarter results ahead of expectations" despite macro uncertainty. The record revenue milestone, all-time-high adjusted operating margin, and stronger-than-expected adjusted EPS provided a constructive setup heading into fiscal 2027. Investor attention centered on the Facet integration, which performed in line with forecast on sales and profitability but carried higher-than-expected amortization and interest expense. Sentiment was tempered somewhat by softer organic aerospace and defense sales and lingering inefficiencies in the power-generation business tied to a production shift in Mexico.
Donaldson's fiscal 2027 guidance calls for sales growth of 5.5% to 9.5% and EPS between $4.22 and $4.38, including approximately $0.12 of dilution from Facet. At the midpoint, management projects record sales above $4.1 billion, operating margin expansion to roughly 16.9%, and free cash flow conversion of 95% to 105%.
Several factors will shape the year ahead. Investors should watch the pace of the Facet integration and the associated interest and amortization costs, which management expects to pressure EPS in the near term even as the deal remains accretive on a cash basis. Operational recovery in the power-generation segment is another key monitor, with management targeting full stabilization by the middle of fiscal 2027.
Demand signals in the company's core aftermarket business, which benefits from vehicle utilization and share gains, will also be important, as will any improvement in organic aerospace and defense sales as supply-chain constraints ease. Finally, the newly renamed Process Filtration segment, combining food and beverage with microelectronics, represents a growth lever worth tracking as Donaldson seeks scalable, above-market expansion.
