Commenting on the first quarter results, Patrick S. Williams, President and Chief Executive Officer, said,

"This was a mixed quarter for Innospec with continued strong results in Fuel Specialties partially offsetting the negative impacts of the January 2026 US winter storm on Performance Chemicals and Oilfield Services.

Performance Chemicals sales were broadly flat with last year, but margins and operating income were significantly impacted by a shutdown of the North Carolina plants due to the US winter storm. We are prioritizing plant repairs in order to meet customer requirements. In parallel, we continue to execute on a range of other topline and margin opportunities identified in the business. We expect these combined efforts to drive sequential growth in the second quarter.

Fuel Specialties had another strong quarter with sales growth and margins that remained at the upper end of our target range. As expected, the business has continued to deliver consistently strong results as our team advances on a broad set of regional and end-market opportunities in traditional fuel, renewable fuel and non-fuel applications.

Oilfield Services operating income and margins improved on the prior year, but overall performance was negatively impacted by the US winter storm. While the Middle East conflict may delay the planned expansion in the region, we remain focused on driving incremental growth from our recent DRA expansion and other opportunities in our completions and production segments. We are cautiously optimistic that these efforts will drive sequential improvement in the second quarter and leave us well positioned for further improvement in the second half of 2026."

Revenues in Performance Chemicals of $169.4 million were up 1 percent over the first quarter of last year as volume reductions of 9 percent were offset by a positive price/mix of 1 percent and favorable currency impact of 9 percent. Gross margins of 16.8 percent decreased by 4.2 percentage points from the same quarter last year. Operating income of $10.7 million decreased 46 percent from $19.8 million in the corresponding prior year period.

Revenues in Fuel Specialties of $181.6 million were up 7 percent from $170.3 million in the first quarter of last year with volume growth of 10 percent and a positive currency impact of 6 percent offsetting a negative price/mix of 9 percent. Gross margins of 35.4 percent decreased by 0.3 percentage points over last year. Operating income of $37.8 million was up 2 percent from $36.9 million a year ago.

Revenues in Oilfield Services of $102.2 million for the quarter were consistent compared with the first quarter of last year. Gross margins of 30.1 percent increased by 1.7 percentage points from the same quarter last year on a richer sales mix. Operating income of $5.6 million increased 37 percent from $4.1 million in the prior year period.

Corporate costs for the quarter were $22.3 million, compared with $17.7 million a year ago. The effective tax rate for the quarter was 22.8 percent compared to 25.7 percent in the same period last year.

------

For the quarter, net cash provided by operating activities was $17.6 million compared to $28.3 million a year ago. As of March 31, 2026, Innospec had $289.1 million in cash and cash equivalents and no debt.

Mr. Williams concluded,

"While the Middle East conflict is creating significant market uncertainty, we are seeing increased opportunities to deliver stand-out service and security of supply for all our customers. Our teams remain focused on elements within our control as we have in prior similar cycles. In parallel, margin enhancement, new technology commercialization and other opportunities remain the priority across our businesses, and we are optimistic about the impact that these actions will have on future results.

Operating cash generation was again positive in the quarter, and our net cash position closed at over $289 million. We have significant balance sheet flexibility for dividend growth, buybacks, organic investment and M&A. This quarter our Board approved a further 10 percent increase in our semi-annual dividend to 92 cents per share, and we completed $6.2 million in share repurchases. Additionally, the Board approved a new $75 million buyback authorization to further enhance shareholder return flexibility."

**Use of Non-GAAP Financial Measures** 

The information presented in this press release includes financial measures that are not calculated or presented in accordance with Generally Accepted Accounting Principles in the United States (GAAP). These non-GAAP financial measures comprise adjusted EBITDA, net income attributable to Innospec excluding special items and related per share amounts together with net cash. Adjusted EBITDA is net income attributable to Innospec per our consolidated financial statements adjusted for the exclusion of interest income, net, income taxes, depreciation and amortization, foreign currency exchange gains, legacy costs of closed operations and adjustment to fair value of contingent consideration. Net income attributable to Innospec and diluted EPS, excluding special items, per our consolidated financial statements are adjusted for the exclusion of adjustment to fair value of contingent consideration, foreign currency exchange gains, legacy costs of closed operations and amortization of acquired intangible assets. Net cash is cash and cash equivalents less total debt. Reconciliations of these non-GAAP financial measures to their most directly comparable GAAP financial measures are provided herein and in the schedules below.

The Company believes that such non-GAAP financial measures provide useful information to investors and may assist them in evaluating the Company's underlying performance and identifying operating trends. In addition, these non-GAAP measures address questions the Company routinely receives from analysts and investors and the Company has determined that it is appropriate to make this data available to all investors. While the Company believes that such measures are useful in evaluating the Company's performance, investors should not consider them to be a substitute for financial measures prepared in accordance with GAAP. In addition, these non-GAAP financial measures may differ from similarly titled non-GAAP financial measures used by other companies and do not provide a comparable view of the Company's performance relative to other companies in similar industries. Management uses adjusted EPS (the most directly comparable GAAP financial measure for which is GAAP EPS) and net income attributable to Innospec excluding special items and adjusted EBITDA (the most directly comparable GAAP financial measure for which is GAAP net income attributable to Innospec) to allocate resources and evaluate the performance of the Company's operations and has provided a reconciliation of adjusted EBITDA and net income attributable to Innospec excluding special items, and related per share amounts, to GAAP net income attributable to Innospec herein and in the schedules below.
