Resideo Q2 revenue beats expectations at $1.98B but slashes full-year guidance by 63%

Resideo reported second-quarter results that beat analyst expectations, with revenue of $1.98 billion versus estimates of $1.94 billion and adjusted earnings per share of $0.83 against expectations of $0.68. CEO Thomas Surran said the company exceeded guidance across all metrics at both consolidated and business segment levels. The company achieved year-over-year revenue growth across substantially all sales channels and product families, driven primarily by customer demand volume. However, operational improvements were partly offset by inflationary input costs and legal settlement expenses. Resideo significantly reduced its full-year revenue guidance to $2.93 billion at the midpoint from $7.85 billion, a 62.7% decrease. Operating margin fell to 6.6% from 9.1% in the same quarter last year. Analysts focused questions on the guidance reduction, new product introductions, HVAC market conditions, and the outlook for OEM security.

Resideo stock plunges 21.5% despite earnings beat on disappointing guidance post-ADI spin-off

Resideo Technologies' stock plummeted 21.5% this week despite beating second-quarter expectations. The smart-home tech company reported adjusted earnings per share of $0.83, exceeding analyst estimates by $0.15, whilst revenue of $1.98 billion topped forecasts by roughly $40 million. The sell-off followed disappointing forward guidance. Resideo recently completed its spin-off of ADI Global Distribution and now projects full-year sales between $2.9 billion and $2.95 billion, with adjusted EBITDA between $605 million and $625 million. The company's gross margin improved by 70 basis points, partly due to tariff refunds. However, investors appear concerned about Resideo's outlook following the major restructuring, as the market reassesses how to value the substantially altered entity.

Resideo Technologies Q2 earnings call highlights.

Resideo Technologies Q2 earnings call highlights. August 12, 2026 Key points. * Resideo exceeded its Q2 outlook, with revenue up 2% year over year to nearly $2 billion, adjusted EBITDA up 19% to $249 million, and adjusted EPS up 26% to $0.83. Results included $27 million in favorable tariff refunds. * The company completed the ADI Global Distribution spin-off on Aug. 3 and repaid $900 million of debt, with plans to repay an additional approximately $200 million in the third quarter. ADI will be reported as discontinued operations beginning in Q3. * Resideo initiated standalone 2026 guidance for revenue of $2.9 billion to $2.95 billion and adjusted EBITDA of $605 million to $625 million, while warning that rising input costs and weaker OEM security demand will pressure results, particularly in the second half. * MarketBeat previews top five stocks to own in September. Resideo Technologies NYSE: REZI reported second-quarter 2026 results that exceeded the high end of its outlook ranges, while completing the Aug. 3 spin-off of its ADI Global Distribution business and outlining a standalone outlook for the remainder of the year. Chief Executive Officer Tom Surran, speaking on his first earnings call as CEO, said consolidated revenue rose 2% year over year to just under $2 billion, a quarterly record. Adjusted EBITDA increased 19% to a record $249 million, while adjusted earnings per share grew 26% to $0.83. The quarter's adjusted EBITDA included $27 million of favorable tariff refunds, primarily received by ADI. Surran also thanked former CEO Jay Geldmacher for his six years of service and cited his role in leading Resideo through acquisitions, a recent spin, and changing market conditions. The company separately announced Shane Harrison as its next chief financial officer. Harrison is scheduled to join Sept. 1. ADI spin-off and balance sheet actions. Resideo completed the ADI Global Distribution spin-off on Aug. 3. Beginning with third-quarter financial statements, ADI will be classified as discontinued operations for the current and prior periods. Resideo's second-quarter discussion included consolidated results because both the Products & Solutions and ADI segments operated under Resideo during the quarter. Chris Lee, Resideo's global head of strategic finance, said reported cash provided by operating activities was $148 million in the second quarter, compared with $200 million a year earlier. The decline was driven primarily by about $45 million in non-recurring business separation activities and settlements, including the termination of the Honeywell Tax Matters Agreement, along with a $20 million increase in cash interest paid. Those effects were partly offset by higher net income and lower cash taxes. The company began reducing leverage after the spin-off, repaying $900 million of principal under its Term Loan B credit facility on Aug. 3. Resideo expects to make an additional repayment of approximately $200 million in the third quarter after completion of the post-closing cash adjustment under the separation agreement with ADI. ADI is scheduled to host its own earnings call and provide more detail on its results and outlook. Surran said ADI will remain an important partner to Resideo. Products & Solutions posts revenue and margin growth. Resideo's Products & Solutions segment reported 4% year-over-year revenue growth, including an approximately 35-basis-point favorable currency impact. Surran said growth occurred across substantially all sales channels and product families, primarily driven by customer demand and volume. Discover more Stock screener subscription EV market analysis Space stocks report Retail-channel growth was supported by higher-value products, including combination smoke and carbon monoxide detectors and new thermostats. In HVAC distribution, revenue returned to growth, led by customer adoption of the Honeywell Home ElitePRO premium smart thermostat. The company also cited new dehumidification and water-filtration products as contributors to category penetration. In electrical distribution, revenue increased on demand for BRK-branded non-connected safety products, particularly in maintenance, repair and operations markets and manufactured housing. The OEM combustion channel, reported as the energy category, posted its seventh consecutive quarter of year-over-year growth, led mainly by demand for higher-priced products in Europe, the Middle East and Africa. Security distribution revenue was flat amid soft demand for security installations tied to existing-home resales. OEM security revenue declined slightly, reflecting lower volumes from a large customer. Surran said the customer is pursuing greater vertical integration, and the affected business is lower margin and not sold under Resideo, First Alert or Honeywell Home brands. Products & Solutions gross margin reached 43.6%, up 70 basis points from a year earlier and 100 basis points sequentially. Surran attributed the improvement to volume, manufacturing and supply-chain execution, and tariff refunds, partly offset by sales mix. Segment adjusted EBITDA rose 6% year over year, primarily due to higher gross profit dollars. The company continued to invest in research and development, which remained approximately 5% of Products & Solutions revenue. Operating expenses increased largely because of higher legal settlement costs. Input costs and market conditions. Management said residential housing conditions remain soft, with little change in existing-home sales or new-home construction. The company expects to grow through product introductions and operational execution rather than broad market improvement. Resideo said costs for memory, metals, printed circuit boards, semiconductors and shipping have increased faster than initially expected. The company implemented price increases during the second quarter, though their benefit will lag because certain customer agreements require notice periods. Management expects the greatest pressure from these temporary input costs in the third quarter before pricing more fully offsets them. Surran said Resideo does not expect material tariff-related cost increases following its assessment of U.S. trade actions announced July 24, nor does it expect material tariff refunds during the rest of 2026. Management expects revenue growth in the second half across all channels except OEM security. Lower volumes from the large OEM security customer are expected to reduce second-half revenue by $40 million to $50 million compared with the prior-year period. The company said the impact will be more pronounced in the fourth quarter and should plateau by the second quarter of the following year. Standalone 2026 outlook. Resideo initiated standalone guidance following the ADI separation. The outlook assumes the company operated independently during the first half of 2026, includes sales to ADI as an external customer, and includes about $80 million of full-year corporate costs allocated to standalone Resideo. Full-year sales to ADI are expected to be approximately $175 million. * Full-year 2026 revenue: $2.9 billion to $2.95 billion * Full-year 2026 adjusted EBITDA: $605 million to $625 million * Third-quarter 2026 revenue: $705 million to $730 million * Third-quarter 2026 adjusted EBITDA: $145 million to $155 million The company did not provide standalone guidance for adjusted earnings per share or operating cash flow during the transition period, saying it intends to do so after completing the ADI post-closing cash adjustment. Resideo expects to resume guidance for those measures with its third-quarter earnings call. Looking ahead, Surran highlighted planned second-half launches including a new smoke and carbon monoxide detector platform and new video surveillance and intrusion security products. He also said the company is reviewing its worldwide manufacturing footprint and operations as part of a longer-term effort to improve efficiency, following previously discussed facility closures in Tianjin and Latrobe.
