Knowles (KN) Q1 2025: Precision Devices Book-to-Bill Surges to 1.15, Signaling Demand Inflection
Knowles delivered Q1 results at the high end of guidance, but the standout was a broad-based rebound in bookings, especially in the precision devices segment, where book-to-bill climbed to 1.15 excluding a major energy order. Management’s proximity manufacturing model and essential end-market exposure are insulating the business from tariff volatility, while capacity utilization gains and inventory normalization are setting up for sequential margin improvement. With a strong backlog and order flow, Knowles is positioned for accelerating growth and margin expansion through 2025.
Summary
- Bookings Momentum in Precision Devices: Book-to-bill above 1.15 reflects broad-based demand recovery and distributor restocking.
- Tariff Insulation Through Proximity Manufacturing: Less than 5% direct revenue and 3% COGS exposed to tariffs, with pass-through pricing power.
- Margin and Growth Acceleration Ahead: Capacity utilization and mix improvements drive sequential gross margin expansion into year-end.
Performance Analysis
Knowles reported Q1 revenue of $132 million, at the high end of guidance, with EPS of $0.18 matching expectations. Segment performance was mixed: MedTech and Specialty Audio (MSA) grew slightly year-over-year to $60 million, while Precision Devices (PD) posted $73 million, flat sequentially and down 2% YoY, but above expectations. Gross margin at the company level was 41%, pressured by mix and a cost-plus supply agreement, but expected to improve as the year progresses.
Cash flow from operations exceeded guidance, aided by customer prepayments, and the company used strong liquidity to repurchase $5 million in shares and reduce debt by $15 million. Inventory at distribution partners is normalizing, driving increased order activity, particularly in industrial end markets. Management’s commentary and Q&A confirmed that order visibility and backlog are building into Q2, supporting confidence in a return to year-over-year growth and margin expansion.
- Precision Devices Bookings Surge: Excluding the $75 million energy order, PD bookings were broad-based, with distributors restocking as inventory nears normal levels.
- MSA Segment Mix Headwinds: Gross margin compressed due to an unfavorable mix and cost-plus supply agreement, but sequential improvement is expected as product mix normalizes.
- Strong Cash Generation and Balance Sheet: Operating cash flow strength enabled both share repurchases and debt reduction, with net leverage at 0.7x and liquidity above $350 million.
The combination of normalized inventory, strong bookings, and operational leverage positions Knowles for accelerating revenue and margin growth through the remainder of 2025.
Executive Commentary
"Our backlog for the MedTech and specialty audio segment for Q2 is strong. Our partnership with our customers is leading to continued innovations, innovative solutions, enhancing the performance of their products. This coupled with our strong performance in the specialty audio business and new opportunities utilizing core competencies and medical markets leads us to continue to believe in our ability to grow throughout 2025 with year-over-year revenue growth accelerating in the second quarter."
Jeffrey New, President and CEO
"We reported fourth quarter revenue of $132 million, down 1% from the year-ago period and at the high end of our guided range. EPS was $0.18 in the quarter, flat from the year-ago period, and at the midpoint of our guidance range. In the first quarter, we generated $1 million in cash from operating activities, exceeding the high end of our guided range, driven by higher-than-expected customer prepayments."

Strategic Positioning
1. Proximity Manufacturing as Tariff Shield
Knowles’ proximity manufacturing model—producing goods near their end market—means that less than 5% of revenue and 3% of cost of goods sold are exposed to tariffs. This structure allows the company to pass through most tariff costs to customers, especially in essential and defense applications, and limits supply chain disruption risk.
2. Essential End-Market Focus Drives Resilience
MedTech and defense end markets are considered essential, with products like implantable devices and RF filters historically insulated from economic shocks. Management cited past downturns where demand rebounded quickly after short pauses, supporting the thesis that Knowles’ core markets can absorb macro volatility better than cyclical peers.
3. Capacity Utilization and Margin Expansion
Underutilized capacity has been a margin drag, especially in Precision Devices, but is now reversing as order flow improves. Management expects sequential gross margin improvement, with company-wide gross margin targeted at 45 to 47% by year-end, driven by higher utilization, improved mix, and the ramp of the specialty film line.
4. Distribution Inventory Normalization Unlocks Demand
Distributor inventory levels have fallen to normalized three to three and a half months, prompting restocking and a surge in bookings. This trend is broad-based across capacitor and filter products and signals that destocking headwinds are largely behind the company.
5. Balance Sheet Strength and M&A Optionality
With net leverage at 0.7x and liquidity above $350 million, Knowles has capacity for both organic investment and selective M&A. The head of corporate development is now focused on inorganic growth after completing recent divestitures, and management signaled readiness to act if the right opportunity arises.
Key Considerations
Knowles enters Q2 with a strong backlog, normalized channel inventory, and a demand rebound in core segments. Its manufacturing model and end-market mix mitigate macro and tariff risks, while operational leverage and balance sheet strength support both organic and inorganic growth options.
Key Considerations:
- Channel Inventory Reversal: Distributor inventory normalization is catalyzing order recovery and reducing visibility risk.
- Tariff Pass-Through Power: Essential device exposure allows Knowles to push through cost increases without major volume loss.
- Specialty Film Ramp: New prototype production line is up, with yields improving and a larger ramp expected in the second half, supporting growth and margin.
- Cash Flow Supports Buybacks and M&A: Robust cash generation funds capital return and strategic flexibility.
Risks
While Knowles is relatively insulated from direct tariff exposure, the company remains vulnerable to unpredictable macro shocks that could impact industrial demand or customer capital spending. Industrial markets are more sensitive to recession risk, and a prolonged downturn could pressure volumes despite essential MedTech and defense exposure. Execution risk remains in the specialty film ramp, and any delays could affect margin recovery.
Forward Outlook
For Q2 2025, Knowles guided to:
- Revenue between $135 and $145 million
- EPS in the range of $0.21 to $0.25
- Adjusted EBITDA margin of 19 to 21%
- Operating cash flow of $10 to $20 million
For full-year 2025, management expects:
- Sequential revenue and margin improvement each quarter
- Capital spending at 5% of revenue to support capacity expansion
Management highlighted:
- Backlog and order activity support year-over-year growth resumption in Q2
- Gross margin to expand sequentially as capacity utilization increases and specialty film ramps
Takeaways
Knowles is emerging from a period of inventory destocking and margin pressure with a solid foundation for growth, underpinned by order momentum and strategic insulation from macro and tariff headwinds.
- Order Inflection: Book-to-bill above 1.15 in PD and strong MedTech backlog set up for accelerating growth and margin expansion.
- Tariff and Macro Resilience: Proximity manufacturing and essential end-market exposure limit risk and support pricing power.
- Watch for Execution on Specialty Film Ramp: Second-half margin and revenue gains depend on successful production scaling and continued order flow.
Conclusion
Knowles enters the remainder of 2025 with building momentum, driven by normalized channel inventory, a strong backlog, and operational leverage. Margin expansion and revenue growth are on track, with additional upside potential from new customer wins and M&A. Execution on the specialty film ramp and continued demand recovery will be the key watchpoints for investors.
Industry Read-Through
