Watsco enters its third-quarter report with a story that sounds better than its stock chart. Last quarter management declared that HVAC distribution had returned to more conventional operating conditions, with residential equipment units growing again and July organic sales running up roughly 4% to 5%. The market has not bought it. Shares have fallen about 14% since that call while the S&P 500 gained 3%. The report due before the open on October 27 has to show whether the volume recovery is real enough to outweigh a gross margin that is still resetting lower.

The Street is looking for earnings of $4.13 a share on revenue of $2.21 billion. That works out to sales growth of nearly 7% but EPS growth of under 4%, and the gap between those two figures is the whole debate in miniature. Part of the revenue lift is acquired. The Jackson Supply deal closed June 1 and adds about $230 million in annualized sales across 25 Sunbelt branches. That suggests close to three points of growth this quarter before any organic contribution. Strip that out, and consensus implies organic growth near the pace management cited for July. A clean beat on revenue would therefore require the summer selling season to have strengthened after July rather than merely held. The earnings whisper of $4.04 sits a bit below consensus, a hint that some investors expect margins to absorb most of the top-line gain. Watsco does not issue formal guidance, so the conference call commentary is the main reference point.

Gross margin is the swing factor. Second-quarter gross margin fell to 27.5% from 29.3% a year earlier, and management attributed most of that decline to lapping the OEM price increases tied to the 2025 A2L refrigerant transition. The year-ago third quarter also carried that tailwind, posting 27.5% with a 130 basis point gain. So the comparison remains difficult. Holding margin roughly flat sequentially would support the view that the reset is a one-time normalization. Another meaningful step down would suggest something more structural. Pricing is part of that question. Realized equipment price rose only about 2% per unit last quarter because smaller contractors did not pass through the full OEM increases. Any improvement there would help on both lines.

The weak spots management flagged deserve equal attention. Commercial sales fell about 8%, largely because of the VRF product transition. New construction is slowing in Florida and Texas, which matters for a distributor with a heavy Sunbelt footprint that just added more Sunbelt branches. Third-party data still showed industry sell-through declining. Inventory also ended June about $100 million above plan. Investors should look for that excess to be worked down without discounting, since clearing it through price cuts would put further pressure on margins. On the positive side, e-commerce reached 37% of trailing sales, OnCall Air volume grew 15%, and the new SupplySync platform for institutional buyers launched. Further gains in these areas would support the share-gain argument even if the industry stays soft.

Sentiment has deteriorated, with the bearish reading deepening to about 37% from 30% before the last report. The stock trades near $296, roughly 20% below its 200-day moving average. It sits in the lower part of its post-earnings range of $277 to $343, and that entire range lies below the previous quarter's $352 to $459 band. Expectations are clearly lower than they were three months ago, which lowers the bar for a positive surprise.

The narrative ultimately rests on one question: whether unit growth carried through the full cooling season while gross margin held near 27.5%. If both hold, last quarter's recovery thesis remains credible despite the stock's slide. If volumes faded after July or margins slipped again, the market's skepticism will look justified.
