Watsco, Inc. (WSO) Income Statement

The sequential improvement from 0.1% growth in 2026Q1 to 7.4% in 2026Q3 indicates demand is recovering, likely driven by a combination of easier year-over-year comparisons and a potential restocking cycle among contractors. However, investors should note that the 2026Q3 recovery to $2.2B still does not exceed the $2.2B achieved in 2024Q3, suggesting the business has not yet regained lost volume. Given the replacement-driven nature of HVAC demand and the aging installed base, a durable return to mid-single-digit organic growth appears plausible but hinges on whether the sequential uptick reflects true end-market pull or channel inventory rebuilding.

The gross margin trajectory is troubling because it decoupled from revenue recovery in the most recent quarter, falling despite a 7.4% top-line expansion. This could reflect several dynamics: a mix shift toward lower-margin equipment at the expense of higher-margin parts and supplies, competitive pricing pressure, or LIFO inventory accounting effects that suppress reported margins during periods of input cost inflation. Compared to industrial distribution peers like Grainger (39.1%) and Fastenal (45.0%), Watsco's 26-28% gross margin reflects its equipment-heavy mix, but the direction of travel matters more than the absolute level; if this compression persists into 2026Q4, it would signal a structural rather than cyclical shift.

Watsco's SG&A as a percentage of gross profit reveals a highly leveraged cost structure: in weak quarters like 2025Q4, SG&A consumed approximately 78% of gross profit, compared to 56% in the stronger 2025Q2. This means that incremental gross profit flows through to operating income at an unusually high rate during periods of revenue expansion, but the reverse is equally true during downturns. The stability of the absolute SG&A line across the dataset suggests management is holding headcount and infrastructure costs steady through the cycle, which supports margin recovery if volume returns but amplifies downside if the recovery stalls. The sequential SG&A increase from $349M in 2026Q2 to $370.7M in 2026Q3 merits attention, as it could indicate reinvestment ahead of confirmed demand.

The 2025Q4 earnings collapse to $71.7M net income (EPS $1.68) from $96.8M (EPS $2.39) a year prior captures the severity of the demand downturn, with the dual compression of both gross margin (27.1% vs 26.7%) and revenue (-10.0%) creating a worst-of-both-worlds scenario. The subsequent quarters show a graded recovery pattern—operating margin improved from 6.1% in 2025Q4 to 10.1% in 2026Q3—but notably has not returned to the 11.4-11.6% range seen in the 2025Q3-2024Q3 comparable periods. This incomplete margin recovery, despite sequential revenue gains, suggests the inflection may be a volume recovery without full margin restoration, which would imply structurally different economics in the post-normalization environment.
