Knowles (KN) Q2 2026 earnings review
Accelerating Growth Driven by Precision Devices as Outlook Upgraded
Knowles delivered a stellar Q2, surpassing the high end of both its revenue and EPS guidance. Driven by a 25% YoY revenue surge in the Precision Devices (PD) segment, total revenue hit $166.8M (+14% YoY). The ongoing ramp of a massive energy order and consecutive quarters of strong bookings prompted management to aggressively raise their FY26 revenue growth outlook to 10-12% (up from a previous 4-6% long-term target). While the top and bottom lines are thriving, operating cash flow decelerated YoY due to a significant inventory build required to support the back-half demand ramp.
🐂 Bull Case
PD revenue exploded 25% YoY. The segment posted a book-to-bill ratio greater than 1.0 for the seventh consecutive quarter, locking in deep visibility for H2 2026 and supporting a massive FY guidance hike.
FY26 Adjusted EBITDA is now guided to grow over 20%. Factory utilization gains and pricing power in PD are rapidly converting incremental revenue into bottom-line outperformance.
🐻 Bear Case
Net cash provided by operating activities dropped 23% YoY to $28.2M, primarily dragged down by a $23.3M YTD inventory build as the company prepares for the energy order ramp.
The MedTech & Specialty Audio segment grew a meager 1.6% YoY. While management previously warned of growth moderation here, its stagnation starkly contrasts with the broader company's acceleration narrative.
⚖️ Verdict: 🟢
Bullish. The successful transition to a high-margin industrial/defense tech supplier is materializing rapidly. The magnitude of the FY26 guidance raise overrides short-term working capital noise.
Key Themes
Precision Devices: Accelerating Core Engine
The PD segment has firmly established itself as Knowles' growth engine. Revenue hit $98.3M, accelerating to 25.2% YoY growth (up from 17.4% in Q1). Management cited broad-based strength across defense, medtech, industrial, and electrification end-markets. A book-to-bill ratio above 1.0 for the seventh straight quarter confirms this is not a short-term blip but a structural acceleration driven by sole-source defensive positions and new program wins.
Specialty Film & Energy Order Ramp
The highly anticipated $75M+ energy order leveraging Knowles' specialty film capacitor technology is actively ramping up. This specific product innovation (pulse power capacitors) allows massive energy storage and rapid release. The volume ramp is increasing factory absorption and should be a primary driver of sustained double-digit growth in H2 2026.
Operating Leverage and Margin Expansion
Higher production volumes are directly feeding margin expansion. PD Adjusted EBITDA margin expanded 310 bps YoY to 23.9%. Management's playbook of pushing 2-4% annual price increases in PD, combined with scaling factory utilization (estimated near 80%), allows incremental revenue to drop straight to the bottom line.
Inventory Build Stifling Cash Flow
Despite a massive beat on earnings, operating cash flow was decelerating. Q2 operating cash flow was $28.2M, down from $36.4M a year ago. This was driven by aggressive working capital consumption: Inventories spiked to $147.1M from $124.6M at year-end. While management explains this as necessary preparation for the energy order ramp, any macroeconomic shock or order pushout leaves them holding expensive working capital.
MedTech & Specialty Audio (MSA) Stagnation
In direct contradiction to the 'accelerated organic growth' narrative applied to the total company, the MSA segment is severely decelerating. Revenue grew just 1.6% YoY to $68.5M (compared to 13.9% YoY growth in Q1). Management had guided for a normalization to 2-4% growth, but printing below 2% signals that the hearing health rebound has fully exhausted its momentum.
Macro Tailwind: Defense Replenishment
Knowles continues to benefit from secular tailwinds in global defense spending, particularly in electronic warfare, radar, and munitions. As legacy stockpiles are depleted globally, Knowles' sole-source RF filter and high-performance capacitor solutions are seeing multi-year booking strength.
Other KPIs
Stable sequentially and accelerating YoY (+120 bps vs 44.2% in 25Q2). The expansion proves that initial yield inefficiencies and scrap costs associated with ramping the new specialty film lines have been successfully mitigated.
Decelerating significantly compared to $39.6M in 25Q2. The drop represents an Adjusted FCF Margin of just 13.7% (down from 27.1% YoY). Higher CapEx ($6.5M vs $5.1M) combined with heavy inventory build drove the contraction.
Guidance
Accelerating. Management explicitly raised this from their prior Investor Day target of 4-6%. The massive upgrade reflects total confidence in the Q3/Q4 backlog conversion, particularly the energy order execution.
Accelerating. Raised from the prior long-term target of 10-14%. Demonstrates severe positive operating leverage as high-margin PD volumes scale.
Stable sequentially, but accelerating YoY. The midpoint ($172M) implies 12.5% YoY growth over Q3 2025's $152.9M, confirming the double-digit trajectory will hold through the fall.
Accelerating YoY. The midpoint of $0.36 implies 9.1% growth over Q3 2025's $0.33, scaling nicely alongside revenue.
Reversing the Q2 dip. The midpoint ($40M) suggests working capital dynamics will begin to normalize as the recently built inventory is converted into finished goods shipments.
Key Questions
Inventory Risk Tolerance
With inventory expanding by nearly $23M YTD to front-run the H2 demand ramp, what contractual protections (like non-cancellable terms) shield the balance sheet if the macro environment forces unexpected order pushouts?
MSA Segment Strategy
MSA growth slowed to just 1.6% YoY. Is this segment structurally constrained to low-single-digits permanently, and if so, what is the strategy to prevent it from diluting total company top-line targets over the next 2-3 years?
Capacity Constraints for 2027
If Precision Devices is consistently booking above a 1.0 ratio and growing 25% YoY, how close are current facilities to maximum utilization, and what level of CapEx will be required in 2027 to avoid capacity bottlenecks?
