Resideo (REZI) Q3 2025 earnings review
Operational Headwinds Halt Momentum; Full-Year Guidance Cut
Resideo reported a sharp slowdown in Q3, with revenue growth of just 2% YoY—a significant deceleration from the ~20% growth seen in the prior three quarters. While adjusted EPS of $0.89 beat estimates, the beat was driven by a one-time tax benefit related to the Honeywell agreement termination. The core operational story was negative, with a problematic ERP system rollout at the ADI segment and HVAC channel weakness in Products & Solutions (P&S) disrupting performance. These issues forced management to cut its full-year 2025 outlook for both revenue and EBITDA, signaling that the 'transitory' headwinds will have a tangible impact on the year.
🐂 Bull Case
Despite top-line challenges, the company's focus on operational efficiency continues to pay off. Gross margin expanded 110 bps YoY, with the P&S segment achieving its 10th consecutive quarter of YoY gross margin expansion.
New products, such as the premium ElitePRO smart thermostats and the First Alert SC5 connected detector, are seeing strong demand and are cited as key drivers of future growth for the P&S segment.
🐻 Bear Case
The company lowered its full-year 2025 guidance for revenue (midpoint down ~$50M) and Adjusted EBITDA (midpoint down ~$40M), indicating the Q3 operational issues are impacting near-term financial targets.
A difficult ERP implementation at ADI and unexpected HVAC channel weakness at P&S reveal execution risks. These issues were more severe than anticipated and were the direct cause of the guidance cut.
⚖️ Verdict: 🔴
Bearish. The sharp deceleration in revenue and the cut to full-year guidance overshadow the continued margin improvements. The operational mishaps in both core segments are significant concerns that challenge the narrative of smooth execution. Until the company demonstrates these 'transitory' issues are fully resolved, the outlook remains clouded.
Key Themes
ADI's ERP Rollout Causes Disruption
The implementation of a new ERP system at ADI, its largest segment, was more problematic than expected. Management admitted to 'additional process headwinds' that led to 'a few points of unachieved revenue growth' and 'lower cash collections'. This fumble directly contributed to the sharp slowdown in ADI's revenue growth from 33% in Q2 to just 2% in Q3 and was a primary reason for the full-year guidance cut.
P&S Segment Hit by HVAC Channel Softness
The Products & Solutions segment was negatively impacted by a 'softer residential HVAC market'. Specifically, a channel inventory glut of equipment using older refrigerants created a 'ripple effect' that reduced demand for Resideo's thermostats. Management believes the issue is transitory and will normalize over the next 1-2 quarters, but it was a key factor in P&S revenue growth slowing from 6% YoY in Q2 to 2% in Q3.
Cash Flow Conversion Weakens Significantly
A major red flag was the poor cash generation this quarter. After adjusting for a one-time $1.59 billion payment to Honeywell, adjusted cash from operations was only $19 million. This contrasts sharply with adjusted net income of $137 million and was explicitly attributed to 'lower cash collections at ADI' due to the ERP implementation issues. This demonstrates a direct link between the operational disruption and poor working capital management.
Structural Margin Expansion Continues
Despite top-line pressures, Resideo's profitability improvements remain a key positive. The P&S segment delivered its 10th consecutive quarter of YoY gross margin expansion, reaching 43.0%, driven by factory efficiencies. ADI posted its 6th consecutive quarter, reaching 22.6%, driven by a better sales mix. This underlying profitability provides a cushion against macro and operational headwinds.
New Products Driving Growth in P&S
The company's strategy of refreshing its product portfolio is showing results. Management highlighted strong demand for the new First Alert SC5 connected smoke and CO detector (developed with Google Nest) and the recently launched premium ElitePRO smart thermostats. These innovations are critical for offsetting softness in other areas and driving future growth for the P&S segment.
Business Separation on Track for H2 2026
The plan to separate ADI and P&S into two independent public companies remains on schedule for the second half of 2026. The company reduced uncertainty by naming the current presidents, Rob Aarnes (ADI) and Tom Surran (P&S), as the designated CEOs of the future standalone entities, allowing them to begin organizational design.
Other KPIs
The segments showed diverging profitability trends. P&S Adj. EBITDA margin expanded 70 bps YoY to 25.0%, demonstrating strong cost control and operating leverage even on slow revenue growth. In contrast, ADI's Adj. EBITDA was flat YoY and its margin compressed 20 bps to 7.6%, as non-recurring costs from the ERP implementation offset gross margin gains.
Despite the weak Q3 cash performance, management raised its full-year outlook for adjusted cash from operations (excluding the Honeywell payment). The previous Q3 guidance was $405-$435M. The new full year guidance suggests a very strong rebound in Q4 collections is expected as the ADI ERP issues are resolved.
Guidance
Management lowered its full-year 2025 guidance. The revenue midpoint was cut by $50M from the prior outlook, and the Adjusted EBITDA midpoint was cut by $40M. This revision directly reflects the impact of the Q3 operational headwinds at ADI and P&S.
Decelerating. The midpoint of $1,873M implies just 0.8% YoY growth compared to $1,858M in Q4 2024. This represents a continued sharp slowdown from the ~20% growth rates seen in the prior three quarters.
Decelerating. The midpoint of $218M implies 16.6% YoY growth. While still healthy, this is a deceleration from the 20-26% YoY growth rates of the past year, reflecting the lower revenue base and ongoing operational normalization costs.
Despite the near-term headwinds, management provided a positive initial outlook for 2026, anticipating YoY growth in both organic revenue and Adjusted EBITDA that will be 'above current analyst estimates'. This suggests confidence that the current issues are indeed temporary.
Key Questions
Quantifying ERP and HVAC Impact
Could you please quantify the revenue and cash collection impact from the ADI ERP implementation in Q3? And for the HVAC headwind, how much of the slowdown was channel inventory destocking versus a change in end-market demand?
Confidence in Cash Flow Rebound
Adjusted operating cash flow was only $19 million in Q3. The raised full-year guidance implies a massive rebound to over $250 million in Q4. What specific actions or leading indicators give you confidence in such a significant working capital release next quarter?
Margin Trajectory in Q4
ADI's adjusted EBITDA margin compressed slightly in Q3 due to ERP costs. Should we expect these non-recurring costs to be fully eliminated in Q4, leading to margin expansion, or will some linger into the end of the year?
