Business Commentary:

Strong Financial Performance:

• Watts Water Technologies Inc. reported record sales of $763 million for Q2 2026, reflecting a 19% increase on a reported basis and a 12% increase organically.
• The growth was driven by strong demand in data centers, favorable pricing, and volume increases, despite some headwinds from product rationalization initiatives.

Data Center Growth:

• The company's data center sales more than tripled compared with the prior year, representing 8% of total sales in the first half of 2026.
• The increase was due to strong demand for cooling solutions, particularly the CoolVol thermal storage tanks, and the company's expanding global data center organization.

Margin and Earnings Improvement:

• Watts Water achieved an adjusted operating margin of 21%, with an adjusted operating income of $160 million, a 15% increase.
• Margin performance was supported by favorable price, volume leverage, and productivity gains, despite anticipated dilution from recent acquisitions and a difficult comparison against prior year benefits.

Outlook and Strategic Positioning:

• The company raised its full-year sales and margin outlook, anticipating organic sales growth of 8% to 11%, driven by data center growth, price realization, and performance in Europe and APMIA.
• The positive outlook is based on the company's strong first-half performance and expectations for Q3, despite ongoing macroeconomic challenges such as higher inflation and geopolitical disruptions.

Product Rationalization and Acquisition Impact:

• The 80-20 product rationalization initiative resulted in a sales reduction of approximately $8 million, impacting organic growth by 1%.
• Acquisitions contributed $28 million in sales, enhancing regional growth, particularly in the Americas and APMIA.

Sentiment Analysis:

Overall Tone: Positive

• "We delivered another quarter of better than expected results, including record sales, operating income, and earnings per share." "Based on our strong first-half performance and third-quarter expectations, we are increasing our full-year sales and margin outlook." "Our balance sheet remains strong and provides ample capacity to support our disciplined capital allocation strategy."

Q&A:

• Question from Andrew Creel (Deutsche Bank): Could you give more color on why the data center TAM expanded from $1B to $2B so quickly? Does this include Europe? Have you made any data center sales there?
  Response: The increase reflects a global opportunity (including Europe/Middle East/Southeast Asia) and a shift towards liquid cooling with new products like CoolVol thermal storage tanks driving higher content per megawatt.

• Question from William Gripen (Barclays): Where are you seeing the most success in data centers? How is new product adoption? What's next in development? What drives the mid-to-high single-digit revenue mix guidance?
  Response: Growth is driven by quality, on-time delivery, and new products like CoolVol. R&D is focused on stainless steel products for liquid cooling. The revenue mix range accounts for the lumpy, project-based nature with visibility strongest in Q3.

• Question from Mike Halloran (RW Beard): What are you seeing in legacy non-data center construction markets (e.g., multifamily)? How are pricing actions positioning you for price-cost dynamics in the back half?
  Response: Residential single-family is worsening slightly; multifamily and institutional (healthcare/education) remain soft. Price was ~6% in Q2, expected to sequentially decline in H2, but the company feels okay about current price-cost dynamics.

• Question from Jeff Hammond (KeyBank Capital Markets): Can you unpack the data center TAM expansion to $2B? How much is Europe? What's the thermal tank TAM? What's the outgrowth vs. the 15-20% market growth?
  Response: The expansion is global, not just Europe, and reflects a shift towards liquid cooling and higher content from new products. The company is focused on profitable, disciplined growth rather than chasing the entire market.

• Question from Brian Lee (Goldman Sachs): What is the geographic mix of data center revenue and how is it expected to evolve? Are there margin differences between regions?
  Response: The Americas are currently growing faster than Asia-Pacific (due to CoolVol) but margins are accretive across all regions, so mix shifts are not a concern.

• Question from James Cole (Jefferies): Do you have multi-year visibility into the data center pipeline? How do you go to market (direct, distribution)?
  Response: Visibility varies by product (longer for large CoolVol tanks, shorter for others). The company uses a multi-channel approach with reps, contractors, and direct work with hyperscalers, often involving multiple sourcing per project.

Contradiction Point 1

Definition and Components of the Data Center TAM Expansion

Contradiction on whether the TAM increase is a new global estimate or a refinement of a previous figure.

Andrew Creel (Deutsche Bank) - Andrew Creel (Deutsche Bank)

2026Q2: The TAM was refined from 'greater than $1B' to $2B, now a global number (including Europe, Middle East, and Southeast Asia)... - [Bob](CEO)

Why did the data center TAM expand from ~$1B to $2B, and does this include Europe, where have there been data center sales? - Andrew Krill (Deutsche Bank)

2026Q2: The TAM increase to $2 billion reflects a more global view (including Europe, Middle East, and Southeast Asia) and incorporates a shift toward liquid cooling and the contribution from the new CoolVault thermal storage tanks. - [Bob](CEO)

Contradiction Point 2

Business Visibility and Data Center Order Pipeline

Contradiction on the level of long-term visibility and order lead times for the data center business.

James Cole (Jefferies) - James Cole (Jefferies)

2026Q2: Visibility varies. For large items like CoolVault tanks, visibility can be up to five months, but overall it's not a multi-year backlog. - [Diane](CFO)

Okay, let's see. The user wants me to rewrite the input into a concise earnings-call question. The input is already a question: "Does Watts have multi-year visibility into its data center pipeline?" I need to check if this can be made more concise while still retaining the core meaning.First, "Does Watts have" can stay. "Multi-year visibility" is a bit of a phrase that might be simplified. Maybe "multi-year visibility" is already concise. "Into its data center pipeline" – "pipeline" here refers to the projects or contracts they have, so maybe "pipeline" is the key term. Is there any redundancy? "Multi-year" implies more than one year, so maybe that's necessary. "Data center pipeline" is specific. The question is asking if the company has a clear view of their data center projects over multiple years. I think the original question is already pretty concise. Maybe rephrase "into its data center pipeline" to "on its data center pipeline" but not sure. Alternatively, "Does Watts have multi-year visibility for its data center pipeline?" But the original uses "into," which is correct. Since the original is already a clear question and concise, maybe there's no need to change it. The rules say to output exactly one line, only the question, ending with a question mark if possible. Since the input is already a valid question, perhaps the answer is to leave it as-is. Wait, the instructions say if the input is already a clear question, output it as-is. But the user might want it rephrased. Let me check the rules again. The user says "If the input is NOT a question, is too vague, or lacks enough information to form a clear earnings-call question, output the input EXACTLY as-is..." So if it is a clear question, we can rewrite it. But if it's already a good question, maybe we leave it. However, the task is to rewrite it into one concise question. So maybe the original can be made more concise. "Does Watts have multi-year visibility into its data center pipeline?" – maybe "Does Watts have multi-year visibility on its data center pipeline?" But "into" is correct. Alternatively, "Does Watts have multi-year data center pipeline visibility?" That's shorter. But does it change the meaning? The original is asking if they have visibility into the pipeline, meaning they can see or plan for multiple years ahead. The rewritten version might be more concise but still accurate. But the user's instruction is to output exactly one line, so maybe the original is acceptable. However, the user wants it rewritten if possible. So perhaps the most concise version is "Does Watts have multi-year data center pipeline visibility?" But I need to make sure it's still a valid question. Alternatively, "Can Watts provide multi-year visibility into its data center pipeline?" But the original is "Does... have," which is more direct. I think the original is already a valid and concise question. Therefore, according to the rules, if the input is a clear question, perhaps we should output it as-is. Wait, the rule says if it's a clear question, do we need to rewrite? The instruction says "rewrite the input into ONE concise earnings-call question." So even if it's a question, we need to make it more concise if possible. So "Does Watts have multi-year visibility into its data center pipeline?" is already concise. Maybe there's no better way. Therefore, the answer is the same as the input. But the user might consider it as already a valid question and not needing changes. So according to the rules, if it's a clear question, output as-is. Wait, no. The rule says "If the input is NOT a question, is too vague, or lacks enough information to form a clear earnings-call question, output the input EXACTLY as-is..." So if it is a question, we should rewrite it. So even though it's a question, we need to make it more concise. So the original is a question. Let me see if it can be made more concise. "Does Watts have multi-year visibility into its data center pipeline?" Maybe "Does Watts have multi-year data center pipeline visibility?" That's shorter. But does "data center pipeline visibility" make sense? It's a noun phrase. The original uses "into its data center pipeline," which is a prepositional phrase. Alternatively, "Does Watts have multi-year visibility for its data center pipeline?" Using "for" instead of "into." But I think "into" is correct here. I think the original is already concise enough. Maybe the user expects it to be left as-is. However, the task is to rewrite it into a concise question. If the input is already concise, then maybe output it as-is. But according to the rules, the user says to output exactly one line, only the final question text. So perhaps - James Ko (Jefferies)

2026Q2: For large items like CoolVault tanks, visibility can be longer (several months). For other products, visibility is shorter, often around five months or less. - [Bob](CEO)
