Why SiteOne (SITE) Shares Are Plunging Today
SiteOne Landscape Supply (NYSE: SITE) shares fell 12.2% after its Q2 results missed Wall Street.

Adjusted EBITDA and full-year guidance also came in below estimates, and the stock hit a new 52-week low.
How this was made

The 30-second read
Why it matters
The combination of EPS, revenue, adjusted EBITDA miss, and weaker-than-expected full-year adjusted EBITDA guidance is likely to trigger estimate cuts and multiple compression, consistent with the large intraday decline and new 52-week low.
Market read
This is a same-day fundamental catalyst with quantified misses and guidance shortfall, making it actionable for traders managing earnings-miss risk and estimate-revision expectations.
What to watch
The article highlights organic revenue down 1% and EBITDA guidance below expectations, but does not detail cost actions, backlog, or segment drivers that could change the forward outlook.
Background
SiteOne reported Q2 results that missed both profit and revenue expectations, and also guided full-year adjusted EBITDA below what analysts expected.
Ticker impact
SiteOne shares fell 12.2% after Q2 EPS ($3.14) and revenue ($1.53B) missed consensus, with adjusted EBITDA and full-year metric guidance also below expectations.
Bearish bias for the next several sessions as the market digests the EBITDA/guidance shortfall and potential revisions to estimates.
The article cites specific misses versus consensus and notes the stock touched a new 52-week low, indicating the market is repricing fundamentals rather than reacting to noise.
Market effects
Weak read-through for landscape supply peers if investors generalize margin pressure and demand softness.
No specific regional impact described.
No global macro or cross-border linkage described.
Counterpoint
The stock’s move to a new 52-week low could attract value buyers if the miss is viewed as temporary and not structural to demand or margins.
