Date of Call: November 4, 2025

Financials Results

• Revenue: $205M (continuing operations), up $51M or 33% YOY; excluding ~$25M sulfur cost pass-through, up ~17%

Guidance:

• Full-year 2025 sales expected to be $700M–$740M (includes ~ $70M higher sulfur cost pass-through)
• Adjusted EBITDA from continuing operations ~ $170M; ecoservices EBITDA ~ $200M (slightly below prior range)
• Adjusted free cash flow raised to $75M–$85M for 2025; FCF modestly lower in 2026 (ex-AM&C)
• 2025 CapEx $60M–$70M; higher CapEx expected in 2026
• Interest expense (continuing ops) $32M–$34M in 2025; cash interest expected $21M–$25M in 2026
• Corporate costs ~ $30M in 2025; modestly lower in 2026

Business Commentary:

• Divestiture and Debt Reduction:
• Ecovyst announced a divestiture of its Advanced Materials and Catalysts segment to Technip Energies for $556 million, with expected net proceeds of approximately $530 million.

• The transaction is expected to close in Q1 2026, with plans to apply between $450 million to $500 million to reduce long-term debt, leading to an expected net debt leverage ratio of less than 1.5x.

• Revenue Growth and Segmentation:

• Third-quarter sales from continuing operations were $205 million, up 33%, with adjusted EBITDA increasing by 18%.

• Growth was driven by favorable contractual pricing for regeneration services and higher sales volume for virgin sulfuric acid. However, lower regeneration services associated with unplanned customer downtime partially offset these gains.

• Strategic Demand Trends:

• Demand for regeneration services is expected to grow due to favorable alkylate economics, while virgin sulfuric acid demand remains strong due to mining and nylon production.

• The mining sector accounts for 20% to 25% of virgin sulfuric acid sales, with copper demand rising due to its role in infrastructure and electric vehicles, and tariffs and onshoring trends supporting domestic demand.

• Capital Allocation and Share Repurchase:

• Ecovyst plans to return capital to shareholders through an active stock repurchase program, with approximately $200 million of remaining capacity in its current $450 million plan.
• The company intends to repurchase up to $20 million of its stock in the fourth quarter of 2025, with further repurchases anticipated in 2026, indicating confidence in undervalued stock prices.
  

  Sentiment Analysis:

  Overall Tone: Positive

  • Management called Q3 "pivotal," expects ~$530M net proceeds from AM&C sale with $450M–$500M used to cut debt to net leverage <1.5x, raised adjusted free cash flow guidance to $75M–$85M, and cited favorable demand trends for regeneration services and virgin sulfuric acid driven by mining and onshoring.

Q&A:

• Question from John McNulty (BMO Capital Markets): Are there specific internal projects you can accelerate now and how will you balance capital deployment between growth and buybacks?
  Response: Priority is value-creation: accelerate Houston storage/logistics and Waggaman investments to meet demand while continuing share repurchases when shares are deemed undervalued.

• Question from John McNulty (BMO Capital Markets): How should we think about pricing momentum carrying into 2026?
  Response: Expect continued contract-driven repricing in regeneration services, higher virgin sulfuric acid pricing supported by elevated sulfur prices and mining demand, and repricing of Waggaman contracts into 2026.

• Question from Patrick Cunningham (Citigroup): How is Waggaman integration progressing and what drives EBITDA uplift—network effects or contract repricing?
  Response: Both—EBITDA upside comes from contract repricing and positive network effects, though some uplift will be offset by a planned turnaround at Waggaman in Q1.

• Question from Patrick Cunningham (Citigroup): Any early thinking on the long-term growth algorithm (EPS growth, FCF conversion, repurchases)?
  Response: Expect strong free cash flow and continued mid-single-digit organic growth potential; will fund high-return organic projects and buybacks, with more 2026 granularity to come.

• Question from Ryan Weis (KeyBanc): With AM&C proceeds, has your target leverage changed from prior 2–2.5x guidance?
  Response: Post-sale net leverage will start below 1.5x (gross ~2x); the 2–2.5x target remains relevant long-term and will ebb and flow with capital allocation choices.

• Question from Ryan Weis (KeyBanc): How do you see nylon demand trending into 2026?
  Response: Expect nylon demand roughly flat into 2026 (status quo) with long-term fundamentals remaining positive.

• Question from Hamed Khorsand (BWS Financial): What clarity do you have from customers on unexpected downtimes and how are you managing inventory?
  Response: Unplanned outages give limited notice; Ecovyst has increased virgin sulfuric acid shipments and managed inventories where possible to offset lower regeneration volumes.

• Question from Hamed Khorsand (BWS Financial): Is a rolling 2-year view the best way to measure the business given maintenance cycles?
  Response: No—turnaround cycles can span 2–4 years, so a 2-year rolling metric understates the longer cycle.

• Question from Laurence Alexander (Jefferies): What does the emerging U.S. mining CapEx cycle mean for capacity needs and structural pricing?
  Response: Near-term (1–5 yrs) rising copper projects will drive significant sulfuric acid demand; company is planning capacity expansions (Houston, Waggaman) and expects long-term tightness and higher sulfuric acid value to support margins.

Contradiction Point 1

Capital Allocation and Shareholder Returns

It involves changes in the company's strategy for capital allocation and shareholder returns, which are critical for investor expectations.

Are there specific projects previously on hold that you can now fully pursue? How do you balance capital deployment into growth opportunities versus returning it to shareholders through buybacks? - John McNulty(BMO Capital Markets)

2025Q3: Both organic and inorganic growth opportunities are exciting, but share repurchases remain a key pillar. We prioritize investments based on what gives the best value creation for shareholders. - Kurt Bitting(CEO)

Why was the strategic review of the Advanced Materials and Catalysts business initiated now? - David Begleiter(Deutsche Bank)

2024Q4: We expect to continue returning a significant amount of cash to shareholders through share repurchases and dividends. - Michael Feehan(CFO)

Contradiction Point 2

Sulfuric Acid Pricing and Demand Dynamics

It involves differing perspectives on sulfuric acid pricing and demand dynamics, affecting financial forecasting and investor expectations.

How do you plan to approach pricing and its impact for next year, and how will this carry into 2026? - John McNulty(BMO Capital Markets)

2025Q3: Sulfuric acid prices are up due to sulfur costs, demand in mining, and Waggaman contracts rolling off. - Kurt Bitting(CEO)

好的，我现在需要处理用户的这个请求。用户是一位专业的金融文章作者，他的任务是总结并精简来自美股上市公司财报电话会议的问答环节的问题。用户强调要简洁、精准，去掉多余的装饰词，同时保持原意，符合美式英语习惯，并且只输出简化后的问题，保留问号。首先，我需要仔细阅读用户提供的原始问题：“Can you explain the sulfuric pricing environment in the first quarter and expectations for virgin pricing going forward? Is there structural price movement beyond pass-through considerations?” 用户的问题有两个部分。第一部分是关于第一季度硫酸价格环境和未来原生定价的预期。这里的“sulfuric pricing environment”可能是指硫酸的定价环境，但可能用户实际想表达的是“sulfuric”是拼写错误，应该是“sulfuric acid”（硫酸），但根据上下文，可能是指某种商品或行业的定价，比如“sulfuric”可能是“sulfur-based”或其他相关词汇的误拼。但根据金融领域的常见术语，可能用户指的是“sulfuric”作为某种原材料或产品的价格环境。不过，也有可能是拼写错误，比如“sulfuric”应为“sulfur-based”或其他。但考虑到用户可能直接复制了原文，我需要保持原词，即“sulfuric pricing environment”。接下来，用户问的是对第一季度的情况和未来原生定价的预期。原问题中的“virgin pricing”需要理解，这里“virgin”可能指的是“virgin material”即原生材料，或者“virgin”作为形容词，指未处理过的原材料。在金融或市场分析中，这可能指原材料的定价，比如原生硫酸的价格。第二个问题询问是否有超出转嫁因素的结构性价格变动。这里的“pass-through considerations”通常指成本转嫁，即生产成本的增加是否能够完全转嫁给消费者。用户想知道是否有结构性的变化，而不仅仅是成本的转嫁。现在需要简化这两个问题。首先，第一部分的问题可以拆分为两个部分：第一季度的定价环境和未来的预期。原问题中的“sulfuric pricing environment”可以简化为“sulfuric pricing environment in Q1”或者“Q1 sulfuric pricing environment”，但可能用户希望更简洁，所以可能改为“Q1 sulfuric pricing environment and future virgin pricing expectations”。但需要检查是否符合美式英语习惯，比如“Q1”是否常用，或者是否需要写成“first quarter”。第二个问题需要简化“Is there structural price movement beyond pass-through considerations?” 可以简化为“Are there structural price changes beyond pass-through factors?” 或者“Is there structural pricing beyond pass-through considerations?” 需要确保用词准确，比如“structural price movement”可能更准确的是“structural price changes”或者“structural shifts in pricing”。现在需要确保两个问题都符合要求，即简洁、精准，没有装饰词，保留问号，并且符合美式英语。例如，原问题中的“Can you explain the sulfuric pricing environment in the first quarter and expectations for virgin pricing going forward?” 可以简化为“Can you explain Q1 sulfuric pricing and future virgin pricing expectations?” 这里将“first quarter”改为“Q1”更简洁，同时去掉冗余的“environment”和“expectations for... going forward”，直接用“future expectations”。第二个问题可以简化为“Are there structural price changes beyond pass-through considerations?” 这里将“Is there structural price movement beyond pass-through considerations?” 改为“Are there structural price changes beyond pass-through considerations?” 使用“Are there”更符合美式英语的疑问句结构，同时“changes”比“movement”更准确。需要检查是否所有信息都被保留，没有改变原意。原问题中的“sulfuric pricing environment”被简化为“sulfuric pricing”，但可能用户希望保留“environment”这个词，不过原问题中的“environment”可能是指市场环境，但简化后可能可以省略，因为“pricing”已经隐含了环境。例如，“sulfuric pricing in Q1”已经足够传达第一季度的定价情况。最终，两个问题合并后是否需要分开？用户给出的原始问题有两个问号，所以可能需要保持两个问题分开。因此，正确的输出应该是两个问题，每个以问号结尾，并且符合所有要求。现在，我需要确保没有使用任何装饰词，比如“Can you explain”可能保持，但用户可能希望更直接，比如“Can you explain...” 是必要的，因为这是问题的结构。所以最终的简化版本可能是：Can you explain Q1 sulfuric pricing and future virgin pricing expectations? Are there structural price changes beyond pass-through considerations?这样既简洁，又保留了原意，符合美式英语习惯，并且每个问题以问号结尾。需要再次检查是否有冗 - Patrick Cunningham(Citi)

2025Q1: Sulfuric acid pricing is driven by sulfur price increases due to U.S. refiners' turnaround activities, which Ecovyst passes through to customers. - Kurt Bitting(CEO)
