Englewood, CO – November 7, 2023 – Innospec Inc. (NASDAQ: IOSP) today announced its financial results for the third quarter ended September 30, 2023. At the same time, the Company announced that it has declared a semi-annual dividend of 72 cents per common share for the second half of 2023 which will be paid on November 27, 2023 to shareholders of record as of November 20, 2023. This brings the annual dividend to $1.41 per share, a 10 percent increase over 2022.

Total revenues for the third quarter were $464.1 million, a decrease of 10 percent from $513.0 million in the corresponding period last year. Net income for the quarter was $39.2 million or $1.57 per diluted share compared to $38.7 million or $1.55 per diluted share recorded last year. EBITDA for the quarter was $56.5 million compared to $59.2 million reported in the same period a year ago.

Results for this quarter include some special items, which are summarized in the table below. Excluding these items, adjusted non-GAAP EPS in the third quarter was $1.59 per diluted share, compared to $1.74 per diluted share a year ago.

Innospec generated cash from operating activities of $58.1 million before capital expenditures of $16.7 million in the quarter. We closed the quarter with net cash of $207.2 million.

EBITDA, income before income taxes and net income excluding special items, and related per-share amounts, are non-GAAP financial measures that are defined and reconciled with GAAP results herein and in the schedules below.

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

“This was another good quarter for Innospec. Our balanced portfolio delivered strong sequential improvement in Performance Chemicals, continued excellent results in Oilfield Services and a steady performance in Fuel Specialties.

In Performance Chemicals, as expected, new contracts drove sequential operating income growth and margin improvement despite continued destocking and end-market headwinds. We believe that destocking pressure has peaked. We are cautiously optimistic that our new contracts together with on-going improvement in our base business has the potential to deliver further sequential growth and margin improvement in the fourth quarter. We feel that our industry-leading 1,4-Dioxane-free and sulfate-free technologies combined with our dedication to customer partnerships and customer service leaves us well placed for continued growth.

In Fuel Specialties, operating income was broadly similar to last year as improved margins offset lower sales. Gross margins were slightly below our target 32 to 35 percent range as we continue to manage inflationary pressure. We expect sequential margin improvement and operating income growth as demand for our chemistries increases into the winter quarters.

In Oilfield Services, despite the expected moderation in production chemicals activity versus the second quarter, the business delivered strong operating income growth and margin expansion compared to the prior year. In the fourth quarter, we anticipate similar results to this quarter, and we expect 2023 to remain on track for significant full year growth and margin improvement.”

Performance Chemicals revenues of $145.2 million were down 9 percent from $159.7 million in the third quarter last year driven by a negative price/mix of 19 percent being partially offset by higher volumes of 7 percent and a positive currency impact of 3 percent. Gross margins reduced by 3.6 percentage points from the same quarter last year to 20.9 percent. Operating income for the quarter of $16.9 million decreased 33 percent on the prior year.

Revenues in Fuel Specialties of $169.3 million for the quarter were down 5 percent from $178.7 million a year ago. Volume reductions of 4 percent and a negative price/mix of 4 percent were partially offset by a positive currency impact of 3 percent. Gross margins of 31.3 percent were 1.4 percentage points above last year. Operating income of $27.6 million was down slightly from $27.9 million a year ago.

Revenues in Oilfield Services were $149.6 million for the quarter, down 14 percent from $174.6 million in the third quarter last year. Gross margins were down by 0.4 percentage points from the same quarter last year to 36.0 percent. Operating income of $16.4 million increased 15 percent over the prior year.

Corporate costs for the quarter were $19.0 million, compared with $17.4 million a year ago. The effective tax rate for the quarter was 17.5 percent compared to 20.9 percent in the same period last year.

For the quarter, cash provided by operating activities was $58.1 million compared to $39.8 million a year ago. As of September 30, 2023, Innospec had $207.2 million in cash and cash equivalents and no debt.

Mr. Williams concluded,

“Our diversified business portfolio continued to perform very well this quarter against a persistent backdrop of economic uncertainty, continued destocking and end-market headwinds.

Cash generation was again excellent this quarter, and our net cash position strengthened to over $207 million. We have a strong, technology-driven growth pipeline in all our businesses. In addition, we have significant balance-sheet flexibility to execute further organic growth investments, complimentary M&A, dividend growth and share repurchases.”

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 EBITDA, income before income taxes excluding special items, net income excluding special items and related per share amounts together with net cash. EBITDA is net income per our consolidated financial statements adjusted for the exclusion of charges for interest expense, net, income taxes, depreciation, and amortization. Income before income taxes, net income and diluted EPS, excluding special items, per our consolidated financial statements are adjusted for the exclusion of foreign currency exchange (gains)/losses, amortization of acquired intangible assets, legacy costs of closed operations, acquisition related costs and adjustment of income tax provisions. 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. Also, 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 adjusted net income and EBITDA (the most directly comparable GAAP financial measure for which is GAAP net income) to allocate resources and evaluate the performance of the Company’s operations. Management believes the most directly comparable GAAP financial measure is GAAP net income and has provided a reconciliation of EBITDA and net income excluding special items, and related per share amounts, to GAAP net income herein and in the schedules below.
