Will ROST report comp store sales growth below +3% in either Q3 or Q4 FY2026?

Management's own FY2026 math is the strongest signal: +7-8% Q1 and +3-4% full year implies H2 quarters must average roughly +1-2% to hit the midpoint. Even with the established beat-and-raise pattern adding 1-2pp, at least one H2 quarter likely lands in the +2-4% range. Given H2 FY2025 comps of +7% and +9% — the toughest YoY compares in recent ROST history — maintaining +3% in BOTH quarters requires sustained absolute sales growth well above historical norms. The question only requires one quarter below +3%, which asymmetrically favors YES.

The structural comp rate of 3-4% places the +3% threshold right at the lower bound of ROST's normalized growth. With cyclical excess of ~1-2pp expected to fade per the committee's CONDITIONAL assessment, H2 comps should converge toward this 3-4% structural rate. However, management's beat-and-raise history in FY2025 suggests the +3-4% full-year guide is conservative — actual full year could be +4-5%, which would allow H2 quarters to remain at +3% or slightly above. The tariff regime change risk (Section 122 ~July 2026) is the swing factor: if tariffs ease, both vendor supply and trade-down tailwinds fade simultaneously, pushing comps toward the 2-3% worst-case floor.

The implied H2 math from guidance is compelling for YES, but I weight the beat-and-raise pattern more heavily than the raw guidance math. In FY2025, ROST's comp trajectory went from flat to +9% — management was consistently conservative. If the full-year actual lands at +5% rather than +3.5% midpoint, H2 quarters could average +3-4%, keeping both above +3%. The Atomic Auditor's EXCEEDING assessment for operational execution partially offsets cyclical normalization concerns. The key tension: excellent management execution vs. extremely tough YoY compares (+7%, +9%).

The math is straightforward: +3-4% full-year with +7-8% Q1 implies H2 must decelerate sharply. Even if management beats guidance by 1pp (to +4-5% full year), H2 quarters need to average only +2-3% to get there. With structural comp at 3-4% and cyclical excess normalizing, the expected H2 comp rate is right at the +3% threshold. Since the question asks if EITHER quarter falls below +3% and Q4 FY2026 faces a +9% prior-year comp (the hardest compare), Q4 is the most vulnerable quarter.

The committee identifies 7/9 lenses depending on tariff/trade-down tailwinds that may normalize in H2 — this is the dominant signal. If even partial normalization occurs (Section 122 ~July 2026), the cyclical 1-2pp excess fades and structural comp of 3-4% becomes the ceiling, not the floor. Volume-driven comp growth (customer count, not ticket) is stickier than price-driven but also more vulnerable to sentiment shifts. Consumer sentiment recovery above 65 would reduce trade-down urgency by 1-2pp per the committee, pushing comp to the 2-3% range.

I anchor on the structural comp rate of 3-4% and the beat-and-raise pattern. If structural comp is 3-4% and management typically beats by 1pp, the expected H2 comp is +4-5% in a normal environment. But H2 FY2026 is not normal — it faces +7/+9% prior-year compares. The two-year stack matters: FY2024 was +3%, FY2025 H2 was +7/+9%, so the two-year stack is +10/+12%. Maintaining the two-year trend requires absolute sales levels 10-12% above two years ago, which is achievable if the trade-down thesis holds. New store growth (5% unit) provides indirect comp tailwind via market share gains.

The guidance math is clear: +3-4% full year with +7-8% Q1 means H2 must average +1-2%. Even with beat-and-raise adding 1-2pp, H2 averages +2-4%. The question asks if either quarter falls below +3%, and with Q4 lapping +9%, at least one miss is highly probable. The worst-case floor of 2-3% comp per Revenue Revealer sits right at the resolution threshold.

Two key facts dominate: (1) structural comp rate is 3-4% with cyclical excess normalizing, placing expected H2 comp right at the +3% threshold, and (2) the resolution only requires ONE quarter below +3% out of two attempts. With Q4 facing a +9% prior-year compare, the probability of both quarters staying above +3% is meaningfully lower than the probability of at least one miss. Tariff expiration risk in July 2026 adds further downside pressure on H2.

The CONDITIONAL revenue assessment and tough H2 compares both point to comp deceleration toward the +3% threshold. Management's beat-and-raise history provides some buffer, but the magnitude of the compares (+7%, +9%) is unprecedented for recent ROST. With both Gravy Gauge and Revenue Revealer identifying cyclical enhancement as temporary, at least partial normalization in H2 is the base case. Slightly above coin-flip given management execution quality.
