FY2026 improved into Q4 as industrial operational execution stabilized, while mobile aftermarket and life-sciences tech-led demand continued to support share gains. Challenges persisted around industrial lumpy project shipping and short-term gross margin pressure from production shifts and constraints.
Management highlighted robust mobile aftermarket growth tied to independent channel strength, product availability, and dealer relationships, including a major North America fleet win driving pull-through.
Across Q1–Q4, management linked growth to food and beverage momentum and disk drive technology demand, framing ongoing product launches and installed-base effects.
Management repeatedly guided cash conversion ranges and tied flexibility to disciplined working capital/capex, while maintaining capital allocation priorities through the Facet transition.
Quarter sequence tracks a full-year narrative from early momentum to Q2 industrial pressure, then sequential recovery and year-end margin expansion with Facet contribution.
Record profitability with operational normalization underway
FY2026 evolved from early-year margin expansion and strategic confidence, to mid-year industrial and gross-margin friction tied to production shifts and footprint optimization. Management then framed recovery as operational work transitioned, capped by record year-end performance and Facet integration, with FY2027 guidance centered on industrial normalization and durable growth engines.
Management emphasized strong first-quarter sales and margin leverage, plus reduced tariff impact estimate. The investor narrative also included footprint optimization progress and back-half catalysts supporting an increased operating margin and EPS outlook.
Read earnings transcriptManagement acknowledged short-term execution challenges in Industrial, attributing gross margin pressure to volume deleveraging and operational inefficiencies (including Mexico turbine production startup) and footprint costs. The strategic counterpoint remained robust backlogs and a maintained record-sales framework.
Guidance was directional and quarter-by-quarter, with management using qualitative step-up language and quantitative operating margin/EPS ranges.
Total company sales to increase between 15% (including pricing ~1%); mobile flat to up 4%; Operating margin guidance increased to 16.2% to 16.8%
Revenue $935.4M; Other 34.6%
Q1 raised FY2026 operating margin and EPS confidence, but investors later saw industrial gross-margin pressure in Q2 before the back-half recovery plan played out.
Consolidated sales guidance of 1% to 5% growth; mobile growth range 2% to 6%; Operating margin guidance revised to 16.0% to 16.4%
Revenue $896.3M; Other 33.4%
Management revised operating margin down due to Q2 gross-margin headwinds, while defending the second-half step-up thesis via backlog and expense leverage.

OE destocking/restocking cadence, independent channel growth, and dealer pull-through outcomes from named programs and wins.
Consumer demand
Across the year, management repeatedly anchored mobile strength in aftermarket availability and share gains, while describing OEM channel volatility from balance-sheet-driven inventory management. Q2 and Q3 commentary highlighted restocking/destocking dynamics and the expectation that OE muted in the mid-year portion but improved later. Q4 added proof points like dealer pull-through from the major North America fleet win and continued China growth.
AI execution
Management consistently described life sciences growth as driven by food and beverage and disk drive momentum, and later tied disk drive demand to technology shifts and higher-content HAMR. In Q2 and Q3, new offerings like liquid cooling and advanced filter introductions were framed as supporting the installed base and future consumables. Q4 reinforced that filtration capability commonality across markets supports scalable growth and higher-than-company-average margin expectations over time.
Capital allocation
Facet was introduced in Q2 as a mix-positive acquisition with meaningful recurring replacement revenue and high margins, and management indicated it would close in the back half. In Q3, guidance was updated to include Facet’s contribution and management highlighted limited cost synergies. Q4 framed Facet as strategically and financially accretive on a cash basis, while also calling out purchase accounting/amortization effects and ongoing integration/testing progress.
Pricing power
Management described industrial results as influenced by lumpy project timing and supplier constraints, particularly in aerospace and defense and parts of IFS. In Q2, order intake was characterized as good but shipping execution and inefficiencies pressured gross margin. Q3 and Q4 focused on resolving the ability to ship engineered systems, improving throughput, and expecting backlog-driven step-ups. Q4’s FY2027 confidence relied on resolving specific industrial site-related ramp items and supply base issues.
Cost discipline
In Q1 management described pricing as competitive within a normalized pricing cycle and reduced annualized tariff impact estimate. In Q3, management said Middle East conflict inflation did not materially come through in Q3 and they were prepared to use surcharges and price increases as appropriate, without factoring meaningful incremental price into the forecast. Q4 reiterated input cost inflation and maintained confidence in full recovery trajectory by mid-FY27.
