Current report

The increase in Adjusted EBITDA was driven by higher sales volume of virgin and regenerated sulfuric acid driven by higher demand, less customer down-time, and contribution from the Waggaman, Louisiana location. In addition, higher virgin sulfuric acid pricing and favorable contractual pricing for regenerated sulfuric acid contributed to the increase. This was partially offset by higher manufacturing costs driven by higher turnaround costs, along with general inflation and higher transportation costs.

Previous report

•Sales increased $51.0 million to $204.9 million. The increasein sales primarily reflects higher average selling prices from the pass-through effect of higher sulfur costs, favorable contractual pricing for regeneration services, increased volume of virgin sulfuric acid, as well as sales associated with the acquired Waggaman, Louisiana location, partially offset by lower regeneration services volume.

Previous report

•Gross profit increased $7.0 million to $52.1 million. The increase in gross profit was primarily due to higher average selling pricing and higher sales volume, partially offset by higher manufacturing costs.

Previous report

•Operating income increased by $0.8 millionto $28.3 million. The increase in operating income reflects higher gross profit offset by higher other operating expense, net.

Previous report

Sales for the three months ended September 30, 2025 were $204.9 million, an increase of $51.0 million, or 33.1%, compared to sales of $153.9 million for the three months ended September 30, 2024. The increase in sales was due to higher average selling prices of $34.3 million and higher overall sales volume of $16.7 million.

Previous report

The increase in average selling prices primarily reflect the pass-through effect of higher sulfur costs and favorable contractual pricing for regeneration services. The impact associated with the pass-through of high sulfur costs was approximately $25 million for the three months ended September 30, 2025. The increase in sales volume was primarily related to the contribution of sales volume from the Waggaman location and higher virgin sulfuric acid sales, partially offset by lower regeneration services due to unplanned and extended customer downtime.

Previous report

Selling, general and administrative expenses were $15.7 million for the three months ended September 30, 2025, an increase of $0.5 million, as compared to $15.2 million forthree months ended September 30, 2024.

Previous report

Other operating expense, net for the three months ended September 30, 2025 was $8.1 million, an increase of $5.7 million, compared to $2.4 million for the three months ended September 30, 2024. The increase in other operating expense, net was primarily due to an increase in loss on disposal of assets of $3.4 million, transaction and integration costs associated with the Waggaman location of $1.3 million, and other costs of $1.0 million, primarily related to restructuring and tax charges.

Previous report

Interest expense, net for the three months ended September 30, 2025 was $8.4 million, an increase of $0.5 million, as compared to $7.9 million for the three months ended September 30, 2024. The increase in interest expense, net was due to lower benefit from our interest rate caps offset by lower interest expense driven by the year over year decrease in variable rates in part due to the reduction in our spread associated with the 2025 Term Loan refinancing transactions and lower outstanding debt during the three months ended September 30, 2025, as compared to the three months ended September 30, 2024.

Previous report

The provision for income taxes for the three months ended September 30, 2025 was $20.2 million, compared to $4.6 million for the three months ended September 30, 2024. The effective income tax rate for the three months ended September 30, 2025 was 98.2%, compared to 23.7% for the three months ended September 30, 2024. The Company’s quarter over quarter effective income tax rate has fluctuated primarily due to an increased discrete tax impact relative to pre-tax book income. The discrete tax items relate to a stock compensation shortfall, intraperiod allocation revaluation of deferred tax assets and liabilities including valuation allowances as a result of the Advanced Materials & Catalysts divestiture, tax expense associated with the recording of accrued penalties and interest on historical uncertain tax positions and a tax benefit related to state tax refunds associated with prior tax years.

Previous report

The total tax expense for the three months ended September 30, 2025 includes a $15.6 million discrete tax expense connected to intraperiod allocation associated with the revaluation of deferred tax assets and liabilities, a valuation allowance against the Company’s Kansas Investment Tax Credits, and an increase in valuation allowance against a portion of the Company’s state net operating losses. In accordance with intraperiod allocation rules, this discrete tax expense is reflected in the tax provision for continuing operations.

Summarized Adjusted EBITDA information is shown below in the following table:

Previous report

Ecoservices: Adjusted EBITDA for the three months ended September 30, 2025 was $63.6 million, an increase of $8.5 million, or 15.4%, compared to $55.1 million for the three months ended September 30, 2024. The increase in Adjusted EBITDA was a result of favorable contractual pricing for regeneration services and higher sales volume of virgin sulfuric acid, partially offset by lower regeneration services volume, due to unplanned and extended customer down time, and higher manufacturing costs driven by general inflation and transportation.

Previous report

(3)Due to reporting the Advanced Materials & Catalysts business as held for sale in discontinued operations, the estimated tax rate used to value deferred tax assets (“DTAs”) and deferred tax liabilities (“DTLs”) needs to be adjusted to remove the Advanced Materials & Catalysts rate. Additionally, the Company reassessed the realizability of its state deferred tax assets, including Kansas Investment Tax Credits and state Net Operating Losses. Due to changes in the Company’s state apportionment profile resulting from the Advanced Materials & Catalysts, it was determined that a portion of these deferred tax assets are no longer expected to be realized. Accordingly, the Company recorded a valuation allowance during the quarter to reflect the reduced expected benefit of these state tax attributes. Given these are a direct result of the sale of discontinued operations and the need to adjust the estimated tax rate and valuation allowances arose because of discontinued operations, the impacts are reflected in continuing operations. Due to these revaluations being solely as a result of the Advanced Materials & Catalysts divestiture and a non-cash item, it is treated as an addback.

Adjusted EBITDA, Adjusted Net Income and Net Debt are financial measures that are not prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and that we use to evaluate our operating performance, for business planning purposes and to measure our performance relative to that of our competitors. Adjusted EBITDA, Adjusted Net Income, and Net Debt are presented as key performance indicators as we believe these financial measures will enhance a prospective investor’s understanding of our results of operations and financial condition. EBITDA consists of net income (loss) from continuing operations before interest, taxes, depreciation and amortization. Adjusted EBITDA consists of EBITDA adjusted for (i) non-operating income or expense, and (ii) the impact of certain non-cash, nonrecurring or other items included in net income and EBITDA that we do not consider indicative of our ongoing operating performance. Adjusted Net Income consists of net income (loss) from continuing operations adjusted for (i) non-operating income or expense and (ii) the impact of certain non-cash, nonrecurring or other items included in net income that we do not consider indicative of our ongoing operating performance. Net Debt consists of total debt less cash and cash equivalents. We believe that these non-GAAP financial measures provide investors with useful financial metrics to assess our operating performance from period-to-period by excluding certain items that we believe are not representative of our core business.

Sales are made on both a purchase order basis and pursuant to long-term contracts. We continued to benefit from positive demand trends for our products and services in the majority of end uses we serve. Strong domestic and export demand for refined products continued to support high refinery utilization rates, while more stringent gasoline standards and growing demand for premium gasoline to power higher-compression and turbo-charged engines continued to drive demand for alkylate and for our regeneration services. In addition, demand for virgin sulfuric acid across a wide range of industrial applications remained favorable.

Most of our contracts feature take-or-pay volume protection and/or quarterly price adjustments for commodity inputs, labor, the Chemical Engineering Index (U.S. chemical plant construction cost index) and natural gas. About 90% of our sales for the year ended December 31, 2024 were under contracts featuring quarterly price adjustments. The price adjustments generally reflect actual costs for producing acid and tend to protect us from volatility in labor, fixed costs and raw material pricing. The take-or-pay volume protection allows us to cover fixed costs through intermittent, temporary production issues at customer refineries.

We evaluated the terms of the amendment in accordance with ASC 470-50 Debt - Modification and Extinguishment and determined that the amendment was a modification of debt. As a result, we recorded $1.0 million of third-party financing fees within debt modification and extinguishment costs in the condensed consolidated statements of income (loss) during the three months ended March 31, 2025.

Previous wording

The Company’s effective income tax rate for the nine months ended September 30, 2025 and 2024, respectively, fluctuated primarily due to an increased discrete tax impact relative to pre-tax book income. The discrete tax items relate to a stock compensation shortfall, intraperiod allocation revaluation of deferred tax assets and liabilities including valuation allowances as a result of the Advanced Materials & Catalysts divestiture, tax expense associated with the recording of accrued penalties and interest on historical uncertain tax positions, and a tax benefit related to state tax refunds associated with prior tax years.

We believe that our existing cash and cash equivalents and cash flows from operations, combined with availability under our ABL Facility, will be sufficient to meet our presently anticipated future cash needs for at least the next twelve months. We may also pursue strategic acquisition or divestiture opportunities, which may impact our future cash requirements. We may, from time to time, increase borrowings under our ABL Facility to meet our future cash needs. As of September 30, 2025, we had cash and cash equivalents of $99.1 million, including $82.0 million cash and cash equivalents from continuing operations and $17.1 million of cash and cash equivalents from discontinued operations, and availability of $85.6 million under our ABL Facility, after giving effect to $3.3 million of outstanding letters of credit, for a total available liquidity of $184.7 million. We did not have any revolving credit facility borrowings as of September 30, 2025. As of September 30, 2025, we were in compliance with all covenants under our debt agreements.

Previous wording

Prior to April 10, 2025, our ABL Facility had one financial covenant with two ratios to maintain. The first ratio compared the total ABL availability against a threshold: the greater of 10% of the line cap (which was defined as the lesser of our revolving loan commitments and the value of our assets) or $10.0 million. The greater of this threshold could not be greater than the total availability of the ABL Facility. The second ratio compared the ABL Facility availability of the U.S. revolving credit facility against a $7.5 million threshold. As of September 30, 2025, we were in compliance with the financial covenant under the ABL Facility. On April 10, 2025, we amended the ABL Facility to, among other things, reallocate all European revolving loan commitments thereunder as U.S. revolving loan commitments. As a result of the amendment, on and after April 10, 2025, the U.S. revolving credit facility comprises all availability of the ABL Facility, and we are only required to comply with the first ratio described above.

The adjustments to net income from continuing operations are shown net of applicable tax rates as determined by the calculation of our quarterly tax provision under interim financial reporting for the three months ended September 30, 2025 and September 30, 2024, except for equity-based compensation. The tax effect on equity-based compensation is derived by removing the tax effect of any equity-based compensation expense disallowed as a result of its inclusion within Section 162(m) of the Internal Revenue Code of 1986 (as amended) and adjusting for the tax effect of the equity-based stock compensation net windfall or shortfall which is recorded as a discrete item.

The following is our unaudited condensed consolidated statements of (loss) income and a summary of financial results for the nine months ended September 30, 2025 and 2024:

Previous report — wording carried elsewhere

Gross profit for the nine months ended September 30, 2025 was $111.4 million, a decrease of $9.0 million, or 7.5%, compared to $120.4 million for the nine months ended September 30, 2024. The decrease in gross profit was primarily driven by higher manufacturing costs of $23.9 million, exclusive of the approximately $49 million of higher sulfur costs, and lower sales volume of $1.8 million, partially offset by higher average selling prices of $16.6 million, exclusive of the pass-through of sulfur costs. The cost of sulfur is generally passed-through to customers at the same rate as incurred resulting in no net impact to gross profit.
