Business Commentary:

Financial Performance and Strategic Execution:

• Ecovyst Inc. delivered full year 2025 adjusted EBITDA of $172 million, exceeding guidance, with a fourth-quarter adjusted EBITDA of $51 million, which is 8% ahead of the prior year.
• The strong financial performance was driven by increased sales volume for virgin sulfuric acid and favorable contractual pricing for regeneration services.

• This strategic move transformed the company's focus towards reliable sulfur solutions for clean fuels and critical materials, enhancing its financial stability.

Demand Outlook and Market Positioning:

• Ecovyst anticipates higher sales of both virgin and regenerated sulfuric acid in 2026, driven by increased mining demand and less customer downtime.
• The company is well-positioned to support the growing demand in mining, especially for copper, with planned investments in storage and logistics.

Capital Allocation and Growth Strategy:

• Ecovyst plans to invest approximately $20 million in growth projects in the Gulf Coast region to enhance storage capacity and rail logistics.
• The company continues to prioritize organic and inorganic growth opportunities while maintaining a commitment to returning capital to shareholders through share repurchases.

"The divestiture... represents a transformative event."

Q&A:

• Question from John McNulty (BMO Capital Markets): Can you help us to think about how much capacity that's freed up for you and as a result how much growth you could necessarily get without having to put in much capacity or incremental capacity?
  Response: The Waggaman assets added ~10% volume and provide a positive network effect by enabling Gulf Coast sites to back each other up, take advantage of more opportunities, and export via deep water dock.

• Question from John McNulty (BMO Capital Markets): Can you help us to quantify that a little bit? [regen contract pricing lift for 2026]
  Response: Expect a similar lift as 2025, typically 15-20% annually as contracts roll off and are re-priced with inflation, providing continued benefit.

• Question from Patrick Cunningham (Citigroup): Are there any specific applications that you want to call out or factors that you would highlight, which is giving you some caution here [in industrial/nylon applications]?
  Response: No specific factors; it's a general sense of caution across a diverse industrial basket. Expect sales into nylon end use to be relatively flat compared to 2025.

• Question from Patrick Cunningham (Citigroup): How does the economics of greenfield versus debottlenecking compare to current acquisition multiples for existing virgin facilities?
  Response: Have met mining demand growth through debottlenecking and acquisitions like Waggaman; will continue this pattern with further debottlenecking and leveraging existing assets.

• Question from Aleksey Yefremov (KeyBanc): Is the expansion... tied to any specific ramp at your customers... or is this just a more general view that you're trying to get ahead of the growth?
  Response: Based on long-term relationships and forward demand visibility from existing and new mining projects, the expansion is to meet the growing, long-term demand for sulfuric acid in mining.

• Question from Aleksey Yefremov (KeyBanc): How would you characterize the current state of the merchant acid market...?
  Response: The market is balanced with stable pricing, though some industrial segments are weaker. Long-term trend, especially in mining, shows growing demand.

• Question from David Begleiter (Deutsche Bank): What would you need to see to get to the low end of the range? And conversely, what type of drivers would you need to get to the high end?
  Response: High end driven by virgin acid price lift from strong demand; low end driven by unplanned outages or macroeconomic deterioration causing pricing/volume declines in virgin acid.

• Question from David Begleiter (Deutsche Bank): With the balance sheet restored to strength, how do you see Ecovyst in 3 to 5 years?... What could be additive to the portfolio?
  Response: Focus on organic growth in sulfuric acid, accretive bolt-on acquisitions adjacent to current chemistries/services, and continued share repurchases as a flexible capital allocation strategy.

• Question from Hamed Khorsand (BWS Financial): Are you done with the investments you need to make at Waggaman?
  Response: No; additional investments are planned, including a maintenance outage this quarter, to further integrate and raise the operating rate of the site.

• Question from Hamed Khorsand (BWS Financial): If nylon or industrial end markets are as weak as you're expecting, are you able to deliver the sulfuric acid to mining that might be a little bit higher in demand?
  Response: Have some flexibility to move product between end uses based on accurate customer forecasts, though most virgin sulfuric acid is sold under supply contracts.

• Question from Laurence Alexander (Jefferies): When you look at the landscape in terms of other assets producing sulfuric acid, is there any titration in terms of the quality of the assets?
  Response: Interest is broad across sulfuric acid assets and other sulfur chemistries/services, as the company serves a wide range of end uses and can utilize various asset types.
