Resideo (REZI) Q3 2025: Gross Margin Rises 110bps as ERP and HVAC Headwinds Prove Temporary
Resideo delivered record gross margin and EBITDA despite dual headwinds from HVAC market disruption and ERP transition costs. Both business segments expanded gross margin, even as operating margin compressed sequentially, highlighting resilient core execution. Management affirmed the transitory nature of current pressures and set expectations for above-consensus growth in 2026, underpinned by new product launches and completed system upgrades.
Summary
- Margin Expansion Outpaces Revenue Growth: Record gross margin gains reflect structural improvements in both ADI and P&S segments.
- ERP and HVAC Disruption Prove Temporary: Leadership emphasizes that operational headwinds will fade by early 2026.
- Separation and Product Pipeline Set Up 2026: Spin-off plans and new product launches position both units for independent growth.
Performance Analysis
Resideo’s Q3 results highlight the company’s ability to drive profitability amid uneven demand and operational friction. Total net revenue increased 2% year-over-year, with both the ADI, global distribution business, and P&S, products and solutions business, contributing low single-digit organic growth. However, the standout signal came from margin structure: gross margin reached a record 29.8%, up 110 basis points, with both segments posting their own multi-quarter streaks of margin expansion. ADI’s gross margin climbed 130 basis points to 22.6%, while P&S delivered its tenth consecutive quarter of year-over-year gross margin gains, now up 500 basis points over the past ten quarters.
Profitability benefited from both operational efficiencies and one-time items. Adjusted EBITDA rose 21% year-over-year, boosted by the termination of the Honeywell indemnification agreement, while adjusted EPS set a new high. Cash from operations, excluding the Honeywell payment, was lower than anticipated due to ERP-related revenue and collection delays at ADI, but management expects a Q4 rebound as system issues subside. Segment performance was uneven: P&S saw top-line growth in retail, OEM, electrical distribution, and security channels, offset by double-digit declines in the HVAC channel due to regulatory-driven inventory disruption. ADI’s ERP upgrade caused a temporary sales and cost drag, but e-commerce and exclusive brands remained growth drivers. The ERP transition also led to higher SG&A and R&D costs, split roughly equally between Q3 and Q4.
- Gross Margin Leverage: Both business units improved gross margin, outpacing revenue growth and signaling structural cost gains.
- Segment Divergence: P&S growth was driven by safety and OEM channels, while HVAC softness and ADI’s ERP friction weighed on overall momentum.
- Cash Flow Timing: Operating cash flow dipped due to the Honeywell payment and ERP collection delays but is expected to recover in Q4.
The quarter’s results reinforce Resideo’s margin improvement thesis, but also expose the sensitivity of operating leverage to transitory disruptions.
Executive Commentary
"Adjusted EBITDA was a record high and approximately the midpoint of our outlook range. Net revenue was within our outlook range, despite incremental macro and operational headwinds that we believe are transitory. And record high adjusted EPS exceeded the high end of our outlook range, due primarily to higher net income associated with terminating the Honeywell indemnification agreement."
Jay Gelmacher, Chief Executive Officer
"Gross margin in the quarter was 29.8%, up 110 basis points year over year. The increase was primarily driven by the more margin accretive activities at ADI and the continued structural operating efficiencies at P&S. Adjusted EBITDA was 229 million in the quarter, up 21% year over year, and in line with the midpoint of our outlook range."
Mike Carlett, Chief Financial Officer
Strategic Positioning
1. Margin Expansion as a Strategic Lever
Resideo’s focus on margin structure is reshaping its long-term earnings power. Both ADI and P&S delivered multi-quarter streaks of gross margin expansion, driven by mix improvements, factory efficiencies, and exclusive brand growth. The company is signaling that margin accretion, not just top-line growth, will be the primary engine for future value creation.
2. Navigating Transitory Disruption
Management is clear that both the HVAC market disruption and ERP implementation are temporary headwinds. The HVAC softness stems from regulatory-driven inventory imbalances at distributors, which are expected to normalize by Q1 2026. The ADI ERP upgrade, while costly and disruptive near-term, is now largely complete, with daily sales rates and pipeline metrics recovering in October.
3. Product Innovation and Channel Diversification
New product launches are central to Resideo’s growth strategy. The P&S business is expanding into premium thermostats with the Elite Pro line, leveraging partnerships (such as with Google Nest) and targeting all price points. Channel diversification—especially strength in OEM, retail, and safety products—helped offset HVAC declines.
4. Strategic Separation and Leadership Alignment
The planned spin-off of ADI and P&S remains on track for the second half of 2026. Both units will become independent companies, led by existing segment heads, with workstreams progressing on organizational design. This separation is intended to unlock focused execution and capital allocation tailored to each business model.
5. Technology Modernization as Competitive Moat
Completion of the ERP upgrade at ADI is positioned as a foundational investment. The new platform is expected to enable cross-selling, pricing optimization, and digital user experience improvements, setting up future margin and growth advantages versus peers.
Key Considerations
Investors should weigh Resideo’s demonstrated margin gains against the near-term noise from operational transitions and macro softness. The business is at an inflection point, with structural improvements potentially masked by temporary setbacks.
Key Considerations:
- Margin Outperformance vs. Revenue Growth: Sustained gross margin expansion is driving earnings leverage and will be the main value driver post-separation.
- ERP and Regulatory Friction: The ADI ERP upgrade and HVAC regulatory inventory glut both weighed on Q3 and Q4, but management expects normalization by Q2 2026.
- Product Mix Shift: Premium thermostat launches and OEM channel growth are diversifying P&S revenue, lessening dependence on cyclical HVAC volumes.
- Separation Execution Risk: The organizational and cost allocation complexities of the planned spin-off will require careful management to preserve operating leverage.
Risks
Resideo faces execution risk as it navigates the final phase of its ERP transition and separation process. The HVAC channel remains exposed to regulatory and housing market volatility, and any prolonged inventory correction could delay the anticipated recovery. Additionally, separation may reveal stranded costs or require unanticipated investment to support standalone operations, potentially dampening margin expansion in the near term.
Forward Outlook
For Q4 2025, Resideo guided to:
- Net revenue of $1.853 to $1.893 billion
- Adjusted EBITDA of $211 to $225 million
- Adjusted EPS of $0.42 to $0.52
For full-year 2025, management adjusted guidance to:
- Net revenue of $7.43 to $7.47 billion
- Adjusted EBITDA of $818 to $832 million
- Adjusted EPS of $2.57 to $2.67
- Cash from operations (ex-Honeywell payment) raised to $410 to $450 million
Management emphasized that ERP-related disruption will be fully resolved by year-end, while HVAC headwinds are expected to subside by Q2 2026. Importantly, initial 2026 planning anticipates organic revenue and EBITDA growth above current consensus, signaling confidence in the underlying trajectory.
Takeaways
Resideo’s Q3 demonstrates that structural margin gains are durable, even as operational setbacks cloud near-term optics.
- Margin Structure Is the Core Story: Multi-year gross margin expansion is now embedded in both business segments, creating a higher earnings baseline for the post-spin era.
- Temporary Headwinds, Lasting Benefits: Both ERP and HVAC disruptions are being managed as short-term events, with underlying demand and pipeline metrics already rebounding.
- 2026 Setup Is Stronger Than It Appears: Above-consensus guidance for next year, new product launches, and the completion of tech upgrades set the stage for a clean separation and improved capital allocation.
Conclusion
Resideo’s third quarter marks a pivotal moment where margin expansion and operational upgrades outweigh the noise from transitory disruptions. With both the ERP transition and HVAC inventory correction nearing resolution, the company is positioned to deliver above-market growth and profitability as it moves toward its planned separation in 2026.
