Key catalyst

Record FY2026 results and FY2027 guidance • 2026-08-26

Base target: $105 / p=50% prob

Biggest risk

The FY2027 outlook embeds higher interest expense and Facet dilution, while organic Aerospace and Defense and Industrial Filtration Solutions showed weakness in FY2026. Execution around production transitions and supply constraints could delay margin recovery. [#IR-2026-08-26]

Invalidation

Break below $82 or thesis failure.

What would change my mind?

Record sales, margins, and earnings, strong aftermarket and Life Sciences growth, and the Facet acquisition provide a credible path to FY2027 EPS growth. Management also expects continued margin expansion and shareholder returns. [#IR-2026-08-26]

Commentary

News tone is positive after the record earnings release and FY2027 guide, but the initial enthusiasm is partly offset by higher financing costs, dilution, and execution risks. Social, options, short-interest, employee, and formal analyst-revision data are unavailable or insufficient in the packet; the social field is therefore not decision-useful.

Record FY2026 results and FY2027 guidance
Donaldson reported record fourth-quarter sales of $1.0588 billion, adjusted EPS of $1.15, and FY2027 guidance for 5.5%-9.5% sales growth and $4.22-$4.38 EPS, including $0.12 of Facet dilution. The release was furnished in the August 26 8-K. [#IR-2026-08-26] [#SEC-8K-2026-08-26]

Short-term Catalysts

Next few weeks

Facet dilution, higher interest expense, and operational inefficiencies
2027-01-31
FY2027 interest expense is projected at $55-$60 million versus $36 million in FY2026, while Facet is expected to dilute EPS by approximately $0.12. Power-generation production inefficiencies and supply-chain constraints remain near-term execution risks. [#IR-2026-08-26]
Prob 65% • Move -7% • Priced-in 45%

Long-term Catalysts

Months to a year

Execution of FY2027 segment growth and margin plan
2027-07-31
Management expects Industrial Solutions growth in the mid-teens, Life Sciences growth of 7%-11%, Mobile Solutions growth of 2%-6%, and operating margin of 16.6%-17.2%. Delivery would support continued earnings compounding, but the forecast remains execution-dependent. [#IR-2026-08-26]

Risks

Analyst target-count and estimate-revision evidence is incomplete, limiting valuation confidence.
Facet integration, amortization, and debt service may offset operating gains.
Industrial Filtration Solutions demand is exposed to cyclical equipment and industrial markets.
Organic Aerospace and Defense performance remains constrained by supply-chain issues.
Production inefficiencies and facility transitions could pressure gross margin into FY2027.
