DeepValue | The New Way Investors Work

SiteOne Landscape Supply (NYSE: SITE) has quietly become one of the most interesting “execution stories” in industrial distribution. At roughly $162.67 per share as of early 2026, the stock is not cheap by any traditional value metric, yet the company just put up an impressive margin defense in a soft demand environment. The central debate now is whether that margin strength is structural or a well-timed peak that the market is overpaying for.

In our latest deep-dive, we walked through SiteOne’s SEC filings, management commentary, and industry data to understand what today’s price already assumes and what has to happen next for investors to get paid. According to the 10-K (2025), p.40, SiteOne is the largest and only national full product line wholesale distributor of landscape supplies in the U.S., now with over 680 branches and about 170,000 SKUs serving more than 430,000 customers. That scale is real, but so are the expectations baked into the stock.

Our bottom line: we rate SITE a WAIT. At current levels, you are paying up for a 2026 margin expansion story that still needs to be validated by pricing, volume, and SG&A trends over the next few quarters.

If you want to stress-test this thesis against other names in your watchlist, this is exactly where automation helps. You can use DeepValue to pull the full SEC history for multiple distributors and contractors at once, then line up valuation, margins, and risk drivers side by side in minutes rather than days.

How SiteOne Makes Money – And Why Margins Matter So Much

SiteOne’s business model is straightforward on the surface: it sells a very wide range of landscape inputs to professional contractors through a dense branch network. According to the 10-Q (2025), p.30, the company operated over 680 branches across 45 U.S. states and six Canadian provinces and offers roughly 170,000 SKUs spanning:

Fertilizer and control products
Irrigation supplies (including PVC pipe)
Hardscapes and lighting
Nursery and related products

Revenue is driven by a mix of:

Maintenance services (relatively stable through cycles)
Repair and upgrade projects
New residential construction
New commercial construction

Demand here is cyclical but diversified. Maintenance categories, especially fertilizer and control, are described as “relatively stable through economic cycles” in the 10-K (2025), p.6. That gives SiteOne a base load of predictable activity. On top of that, it rides the more volatile construction and remodel cycles, which can swing volumes and pricing power.

The important nuance for investors is how pricing and cost structure show up in the P&L:

Gross margin is highly sensitive to price realization. In FY2024, gross margin declined due to “lower price realization,” as the company noted in the 10-K (2025), p.45.
SG&A leverage can be a mix of real structural savings and non-recurring noise. Management explicitly tied 4Q25 SG&A rate improvement partly to “lower one-time charges” in the 8-K (2026), p.2.

That combination means the market is correctly focused on:

1) Whether SiteOne can keep price realization modestly positive as deflation in key products like PVC and grass seed fades, and

2) Whether the SG&A leverage we just saw is repeatable without leaning on one-time items.

What Did SiteOne Deliver in 2025?

The starting point for any investment call here is the 2025 performance. SiteOne’s FY2025 print, released in February 2026, checked a lot of boxes that a “margin story” needs to check.

According to the 8-K (2026), p.2–3 and accompanying earnings release via Business Wire (Feb 11 2026):

Net sales: $4.70B, up 4% year over year
Organic Daily Sales (ODS): +1%
Gross margin: 34.8%, up 40 bps
SG&A rate: 30.1%, down 40 bps
Adjusted EBITDA: $414.2M, up 10%
Adjusted EBITDA margin: 8.8%, up 50 bps

Those are legitimate improvements in a soft tape. Management also kept capital allocation active, with $97.7M of share repurchases and eight acquisitions representing roughly $55M in trailing-twelve-month sales, as disclosed in the 8-K (2026), p.1 and Business Wire (Feb 11 2026).

Two things stand out to us:

1. Margin resilience with only modest top-line help. With ODS only +1%, SiteOne still expanded both gross margin and EBITDA margin. That is exactly what a “scale and execution” bull thesis wants to see.

2. Guidance raises the bar further. Management guided FY2026 adjusted EBITDA to $425M–$455M on “flat” demand and pricing up 1–3%, per the 8-K (2026), p.3. There is also a 53rd-week headwind reducing EBITDA by an estimated $4M–$5M, which subtly tightens the hurdle for an optical beat.

In other words, the story going forward is not about a big revenue rebound. It is about continuing to squeeze more profit out of a flat volume environment.

Why the DeepValue Team Rates SITE a “WAIT”

From a pure business-quality perspective, we like a lot about SiteOne: national scale, a wide product set, a stable maintenance component, and demonstrable margin progress. That is not the problem.

The issue is valuation versus margin of safety.

Our analysis of external financial data (FMP) shows SITE trading around:

P/E: ~52x
EV/EBITDA: ~24.3x
Market cap: roughly $7.2B

At those multiples, you are not buying a cheap cyclical distributor in the trough. You are effectively underwriting that:

EBITDA can step up from $414M in FY2025 to the guided $425M–$455M in FY2026, and
The margin gains we just saw are durable, not one-time.

Our base case in the one-pager pegs fair value around $165 with a 50% probability, assuming FY2026 EBITDA of about $440M under flat demand and modest positive pricing. The bull case, worth about $195 per share, only kicks in if larger 2026 acquisitions integrate cleanly, pushing EBITDA toward $465M without margin slippage. The bear case pulls back to $125 per share if volume-based supplier incentives roll off and EBITDA stagnates near $425M.

At ~$163, the stock is much closer to pricing in the base-to-bull range than the bear. That leaves no real margin of safety if the next few quarters show that pricing power or SG&A leverage are weaker than hoped.

According to the 10-K (2025), p.6 & p.88, SiteOne’s balance sheet is solid: maintenance categories provide some cyclicality buffer, and the ABL structure only introduces covenant pressure if revolver availability falls below 10%. That is good news for solvency risk, but it does not protect you from multiple compression if the market walks back its margin expectations.

Our view: today’s buyer is making a timing and execution bet. We would rather see another couple of quarters of data before committing fresh capital.

Is SITE Stock a Buy in 2026 – Or Should Investors Stay Patient?

This is the question we get most often from clients watching SITE grind higher.

We think it is helpful to frame it around three observable pillars:

1. Pricing contribution

2. SG&A leverage quality

3. M&A and integration discipline

1. What needs to happen with pricing?

Management is guiding 2026 pricing at +1% to +3%. For the quarter ended Sept. 28, 2025, pricing contributed about 1% to ODS, but for the nine months year-to-date, pricing impact was “negligible,” per the 10-Q (2025), p.36. That already hints at a fragile pricing dynamic in the face of commodity deflation.

The thesis increases if:

Over the next two quarters, pricing remains clearly positive in the ODS bridge, and
EBITDA margins expand at least ~50 bps year over year, consistent with our upside checkpoints.

The thesis decreases if:

We see two consecutive quarters where pricing contribution drops to ~0% or negative, even as management reiterates the +1–3% pricing framework, as flagged in the risk section referencing the 8-K (2026), p.2 and 10-Q (2025), p.36.

Given FY2024’s experience of lower price realization pulling down gross margin, we see pricing as the leading indicator of whether the current valuation is sustainable.

2. How “real” is SG&A leverage?

SiteOne is leaning heavily on operational initiatives like:

“Focus branch improvements”
Delivery cost reduction

These are explicitly linked to “continued SG&A leverage” in management’s commentary, as noted in the Business Wire earnings release (Feb 11 2026). That is encouraging. But the filings remind us not to over-credit:

4Q25 SG&A improvement included a meaningful contribution from lower one-time charges, per the 8-K (2026), p.2.
4Q24 saw $11.4M of impairment-related charges and $1.0M of reclamation and repair costs associated with branch consolidation, as detailed in the 10-K (2025), p.72.

For us, the key SG&A test in 2026 is:

Can SiteOne keep driving SG&A rate lower without a new wave of restructuring or impairment charges that just move expenses into below-the-line buckets?

If SG&A improvement keeps coming with a footnote about “lower one-time charges,” we would treat a large portion of the margin story as non-structural.

3. Will M&A help or hurt?

SiteOne has built much of its scale through acquisitions. Management described the 2026 pipeline as “robust” and expects average deal sizes to normalize upward again, according to the AOL Q4 2025 earnings call transcript (Feb 11 2026). That can be a major EPS driver—or a major headache.

The proxy’s “Acquisition Integration and Performance” scorecard sits at 50% and explicitly cites underperformance from certain deals, per the DEF 14A (2025), p.42. The 10-K (2025), p.22 similarly warns that larger acquisitions can make delays and dilution “particularly acute.”

In our bull scenario, larger 2026 deals integrate cleanly, adding scale and driving FY2026 EBITDA to about $465M without new impairment noise. In the bear case, SiteOne essentially repeats the 4Q24 playbook: bigger deals, more underperformance, and another round of impairments and closure costs that cause the market to re-rate the stock as a less reliable compounding story.

Our stance is that until we see evidence of cleaner integration outcomes, we do not want to pay nearly 24x EBITDA for what could turn into a lumpy consolidation roll-up.

If you are running a portfolio of similar “roll-up plus margin story” names, automating this kind of risk mapping is crucial.

Will SiteOne Deliver Long-Term Growth?

Long-term, the SiteOne story is about three strategic levers: consolidation, private label expansion, and working capital discipline.

Consolidation in a fragmented market

Landscape supply distribution is still fragmented, with lots of regional and local players. SiteOne positions itself as “the largest and only national full product line” distributor, a point it repeats in the 10-K (2025), p.40. Its path to sustained growth is to keep rolling up smaller distributors, optimizing the branch network, and deepening local density to lower unit delivery and overhead costs.

There is evidence that branch optimization works: management has discussed closing or consolidating branches and still retaining about 75–80% of sales, as highlighted in the AOL Q4 2025 call transcript (Feb 11 2026). That is powerful if it is repeatable across the network. But there is also clear evidence that consolidation is messy: the 4Q24 impairment and branch-related charges in the 10-K (2025), p.72 show that not every acquisition or branch move is value-accretive out of the gate.

Over a 2–5 year horizon, our roadmap expects:

A more repeatable consolidation engine where integration timelines shorten and margin dilution risk falls.
A branch network that keeps densifying, lowering cost per delivery and enabling tighter service radius.

If management can improve on its current 50% integration scorecard, we see a credible path to a structurally higher earnings base.

Private label as a margin driver

Private label is another underappreciated lever. Proprietary brands like LESCO accounted for about 14% of FY2024 net sales, per the 10-K (2025), p.7. Management has floated long-term potential for private label mix to rise toward 25–30%, according to the AOL Q4 2025 earnings call transcript (Feb 11 2026).

Private label matters because:

It can raise gross margin via mix without relying on pure price hikes.
It deepens customer stickiness, as contractors get used to specific formulations and SKUs.

Executed well, this strategy can cushion gross margin through cycles, including periods of commodity deflation when list pricing is under pressure. We will be watching disclosures around proprietary mix over the next several filings for tangible progress.

Working capital and cash conversion

The third piece of the long-term story is less glamorous but equally important: working capital management.

For the nine months ended Sept. 28, 2025, operating cash flow fell to $135.7M from $164.0M in the prior year, largely because SiteOne pulled forward inventory purchases ahead of tariffs, according to the 10-Q (2025), p.10 & p.31. Inventory alone used $131.6M of cash.

In our 6–18 month checkpoints, we are specifically watching whether those tariff-driven inventory dynamics:

Normalize, leading to better cash conversion, or
Persist, which would signal weaker demand or higher markdown risk.

Longer term, any improvement in inventory turns and working capital discipline strengthens the quality of earnings and supports more consistent buybacks and M&A without levering up.

Macro and Industry Setup: Headwinds vs Tailwinds

No SiteOne analysis is complete without looking at the construction and remodeling backdrop.

On the headwind side:

Builder sentiment remains weak. The NAHB Housing Market Index was 37 in January 2026, signaling cautious builders and downside risk for new residential demand, per NAHB (Jan 16 2026).
The Harvard Joint Center for Housing Studies expects U.S. remodeling growth to downshift into late 2026, with LIRA slowing from about 2.9% to 1.6%, reducing the repair and upgrade pool that represents around 30% of SiteOne’s sales, according to JCHS (Jan 26 2026) and SiteOne IR (Oct 29 2025).
Commodity deflation in PVC pipe and grass seed has weighed on reported sales and pricing, as noted in the 10-Q (2025), p.30.

On the tailwind side:

NAHB expects single-family housing starts to rise about 4% in 2026 to roughly 1.05M, suggesting a manageable rather than catastrophic downturn in new residential, based on NAHB (Feb 18 2025).
Maintenance categories stay resilient; SiteOne notes fertilization and control products are “relatively stable through economic cycles” in the 10-K (2025), p.6.
As deflation dissipates, management’s +1–3% 2026 pricing guide looks more achievable, which would support gross margin, as emphasized in the Business Wire earnings release (Feb 11 2026).

Our read is that the macro setup is muddled but not disastrous. The bigger swing factor for SITE’s equity story remains self-help: pricing, SG&A execution, and M&A outcomes.

What Should Investors Monitor Over the Next 6–12 Months?

We think about SITE in terms of checkpoints rather than a single buy/sell call. Here is what we will be watching:

90-day checkpoints

By about May 2026:

Pricing in ODS remains positive. If management does not explicitly call out positive pricing contribution in the ODS bridge, we would reduce exposure. This is linked to the FY2026 +1–3% pricing framework in the 8-K (2026), p.2.
SG&A improvement is structural. If SG&A rate only improves because “one-time charges were lower,” as in 4Q25, we would treat this as noise, again referencing the dynamic in the 8-K (2026), p.2.
Focus branch and delivery initiatives show tangible results. We are looking for management to connect specific projects to SG&A leverage, consistent with the Business Wire release (Feb 11 2026).

180-day checkpoints

By about August 2026:

Cash conversion improves. Inventory that was pulled forward for tariffs should normalize; another period of heavy inventory use of cash similar to the $(131.6)M in the 10-Q (2025), p.10 would be a red flag.
Demand in new residential and repair/upgrade does not deteriorate further. If management begins talking about discounting to move product, and ODS volumes step down sharply as flagged in the 10-Q (2025), p.30, we would worry about negative operating leverage.
M&A cadence vs. integration quality. An uptick in deal sizes without any improvement in the integration scorecard from the DEF 14A (2025), p.42 would make us cautious about multiple risk.

If SiteOne clears these hurdles and prints 1–2 quarters where pricing and SG&A leverage both look solid, we would be more comfortable shifting from WAIT to a more constructive stance.

Our Takeaway: Good Business, Demanding Price

Putting everything together:

Business quality: Solid. National scale, diversified demand, and a credible cost and private-label story.
Execution: Mixed but improving. FY2025 margins impressed, but integration and one-time SG&A dynamics keep us honest.
Valuation: Demanding. A P/E north of 50x and EV/EBITDA around 24x leave little room for disappointment.
Stock call: WAIT. We want more data on pricing durability, SG&A quality, and M&A integration before paying up.

For investors with a long watchlist and limited time, a name like SITE is a good candidate to monitor with automated deep research rather than constant manual re-underwriting.
