Ashland reports second quarter fiscal 2025 results and revises full-year outlook

WILMINGTON, Del., April 30, 2025 – Ashland Inc. (NYSE: ASH) today announced financial results1 for the second quarter of fiscal year 2025, which ended March 31, 2025, and revised its full-year fiscal 2025 outlook. Ashland, a global additives and specialty ingredients company, holds leadership positions in high-quality, consumer-focused markets including pharmaceuticals, personal care and architectural coatings.

"Our second-quarter performance reflected a mixed demand environment and lower-than-expected sales volumes, while pricing generally aligned with planning assumptions excluding intermediates. This combined impact was partially offset by the momentum of our cost savings program and a well-managed production recovery that followed our strategic pull-forward of maintenance turnarounds into the first quarter," said Guillermo Novo, chair and chief executive officer of Ashland.

“Life Sciences demonstrated strong volume momentum and a clear demand recovery, supported by effective execution and the stabilization of customer inventory levels. This reinforces our outlook for renewed pharma growth. Personal Care's core additive business showed resilience while continuing to navigate softer European demand and specific customer challenges. Specialty Additives experienced anticipated volume declines in China, and competitive intensity remained high in export markets, such as the Middle East, Africa, and India. However, strong execution in other markets partially compensated for these headwinds. Intermediates margins were below expectations due to persistent pricing pressure and reduced production in response to the challenging demand environment.”

Novo continued, "With our portfolio optimization now complete, highlighted by the sale of Avoca and the full identification of our $30 million cost reduction plan in the second quarter, our key focus moving forward is accelerating cost savings from our $60 million manufacturing optimization plans. Overall, we are successfully delivering on our cost savings initiatives and are on track to exceed our full-year target. The early benefits are evident in the robust EBITDA margins, above 30 percent, achieved by our Life Sciences and Personal Care business units this quarter, despite macroeconomic headwinds. We anticipate the financial impact of our cost

reduction and manufacturing optimization initiatives will accelerate through the second half of this fiscal year and into fiscal 2026, supporting our results in this uncertain market."

Second-quarter sales were $479 million, a decrease of 17 percent compared to $575 million in the prior year. This included a reduction of approximately $67 million or 12 percent due to the Portfolio Optimization initiatives, which involved curtailing or divesting certain lower-margin products. Excluding these initiatives, sales declined by five percent year-over-year. Year-over-year organic sales volume decreased two percent, while Intermediates delivered improved volumes and Life Sciences organic volumes were stable. These positive trends were more than offset by organic volume declines in Personal Care and Specialty Additives. Overall pricing decreased by roughly two percent from the prior year, primarily driven by lower carry-over pricing from fiscal 2024 actions within the Life Sciences and Specialty Additives segments, as well as decreased intermediates pricing. Foreign currency movements had an unfavorable impact of $6 million, or one percent, on sales.

Net income totaled $31 million, a decrease from $120 million in the prior year. Income from continuing operations was $30 million, down from $121 million in the prior year, resulting in diluted earnings per share of $0.63, compared to $2.40 in the prior year. Excluding intangibles amortization expense, adjusted income from continuing operations was $46 million, down from $64 million in the prior year, or $0.99 per diluted share, compared to $1.27. Adjusted EBITDA was $108 million, a 14 percent decrease from $126 million in the prior year, primarily due to the impact of Portfolio Optimization and lower organic sales. This decline was partially moderated by lower selling, administrative, research and development (SARD), and production costs compared to the prior year. Excluding the $13 million reduction related to Portfolio Optimization, Adjusted EBITDA decreased by four percent year-over-year.

Average diluted shares outstanding totaled 47 million in the second quarter, down from 51 million in the prior-year quarter following the company’s share repurchase activities over the past 12 months. Ashland repurchased 1.5 million shares during the second quarter and now has $520 million remaining under the existing evergreen share repurchase authorization.

Cash flows from operating activities were $9 million, a decrease from $54 million in the prior-year quarter, primarily reflecting lower earnings, trade working capital fluctuations and higher restructuring payments related to portfolio optimization initiatives. Ongoing free cash flow2 totaled negative $6 million compared to $4 million in the prior-year quarter. The sale of Avoca, along with excess land sales, generated net investing cash inflows of $27 million during the quarter.

Reportable Segment Performance

To aid in the understanding of Ashland’s ongoing business performance, the results of Ashland’s reportable segments are described below on an adjusted basis. In addition, EBITDA and Adjusted EBITDA are reconciled to operating income in Table 4. Free cash flow, ongoing free cash flow and Adjusted operating income are reconciled in Table 6 and Adjusted income from continuing operations, Adjusted diluted earnings per share and Adjusted diluted earnings per share excluding intangible amortization expense are reconciled in Table 7 of this news release. These adjusted results are considered non-GAAP financial measures. For a full description of the non-GAAP financial measures used, see the “Use of Non-GAAP Measures” section that further describes these adjustments below.

Life Sciences

Second-quarter sales for Life Sciences totaled $172 million, a 23 percent decrease compared to the prior year. This decline was primarily driven by the divestiture of the Nutraceuticals segment and the exit of the low-margin nutrition business, which together comprised the Portfolio Optimization efforts, reducing sales by $42 million or 19 percent. Excluding the impact of Portfolio Optimization, Life Sciences sales decreased by 4 percent year-over-year, mainly due to lower carry-over pricing from fiscal 2024 actions within the pharma end-market. Driven

by increased quarter-over-quarter pharma demand, overall Life Sciences organic sales volume remained consistent with the prior year. This pharma demand improvement was broad-based across most regions and technologies, including cellulosics and vinyl pyrrolidone and derivatives (VP&D). Organic sales in nutrition end-markets saw moderate improvement due to share gain initiatives. Foreign currency movements had an unfavorable impact of $3 million on sales compared to the prior year.

Adjusted operating income was $43 million, compared to $50 million in the prior year. Adjusted EBITDA was $56 million, a 15 percent decrease from $66 million in the prior year. The lower Adjusted EBITDA primarily reflects the $8 million impact of Portfolio Optimization in the second quarter and lower pharma carry-over pricing, partially offset by the favorable impact of lower production costs. Excluding Portfolio Optimization, Adjusted EBITDA decreased by 3 percent. Foreign currency movements had an unfavorable impact of $1 million on Adjusted EBITDA compared to the prior year.

Personal Care

Second-quarter sales for Personal Care were $146 million, a 14 percent decrease from $169 million in the prior year. This decline was primarily attributed to Portfolio Optimization, which reduced sales by approximately $15 million or 9 percent. This optimization effort largely stemmed from the performance and subsequent divestiture of the Avoca business line, as well as the exit of the low-margin oral-care business. Compared to the prior year organic sales volumes declined by three percent. This volume decrease was a result of low-single-digit growth in core skin and hair care being more than offset by customer-specific weakness in biofunctional actives, order timing in oral care, and continued soft demand in Europe. Personal Care’s “globalize” business lines of microbial protection and biofunctional actives delivered double-digit quarter-over-quarter sales growth; however, both were down compared to the prior year. Additionally, foreign currency movements had an unfavorable impact of $2 million on sales compared to the prior year.

Adjusted operating income was $27 million, compared to $25 million in the prior year. Adjusted EBITDA totaled $44 million, a two percent decrease from $45 million in the prior year. Portfolio Optimization reduced Personal Care Adjusted EBITDA by approximately $3 million during the second quarter. The lower Adjusted EBITDA primarily reflects the impact of Portfolio Optimization and lower organic sales, partially offset by the favorable impact of increased production volumes. Excluding Portfolio Optimization, Adjusted EBITDA increased by five percent. Foreign currency had a negligible impact on Adjusted EBITDA compared to the prior year.

Specialty Additives

Second-quarter sales for Specialty Additives were $134 million, a 15 percent decrease from $157 million in the prior year. The primary driver of this decline was Portfolio Optimization, which reduced sales by approximately $10 million or six percent, mainly through the exits of low-margin construction business. Excluding this impact, organic volumes decreased by six percent. This volume decrease resulted from continued growth in performance specialties across end-markets being more than offset by lower coatings volumes. The decline in Specialty Additives volume stemmed mainly from volume declines in China, which aligned with expectations, and continued high competitive intensity in export markets, such as the Middle East, Africa, and India (MEAI). This outweighed a coatings volume recovery in North America and Europe. Overall pricing decreased by low-single-digits, largely due to lower carry-over pricing from fiscal 2024 actions within the coatings end-market. Additionally, foreign currency movements had an unfavorable impact of $2 million on sales compared to the prior year.

Adjusted operating income was $10 million, consistent with the prior year. Adjusted EBITDA totaled $26 million, down from $27 million in the prior year. The decrease in Adjusted EBITDA primarily reflects the impact of Portfolio Optimization and lower pricing, partially offset by favorable production volumes and costs. Portfolio Optimization reduced Adjusted EBITDA by approximately $2 million during the second quarter. Excluding this, Adjusted

EBITDA increased by $1 million compared to the prior year. Foreign currency had a negligible impact on Adjusted EBITDA compared to the prior year.

Intermediates

Second-quarter sales totaled $37 million, an 8 percent decrease from the $40 million reported in the prior year. Within this, merchant sales remained stable at $27 million compared to the prior year. Captive butanediol (BDO) sales, recognized at market-based pricing, decreased by $3 million to $10 million. The overall sales decline was primarily due to generally lower pricing in both BDO and n-methyl-2-pyrrolidone (NMP). Foreign currency had a negligible impact on sales compared to the prior year.

Adjusted operating loss was $1 million, compared to an income of $9 million in the prior year. Adjusted EBITDA was $2 million, a decrease from $12 million in the prior year, primarily reflecting lower pricing and production volumes. Foreign currency had a negligible impact on Adjusted EBITDA compared to the prior year.

Unallocated & Other

Unallocated and other expense was $11 million compared to $45 million in the prior-year quarter, primarily reflecting a reduction in restructuring and separation costs associated with Portfolio Optimization and a gain on land sale. Adjusted unallocated and other expense EBITDA was $20 million versus $24 million in the prior-year quarter.

Tariffs

Ashland recognizes the current economic headwinds and uncertainties created by tariffs and global trade policies. The company is closely monitoring changes in tariff policies and adjusting its strategies to optimize performance. To navigate this evolving landscape, Ashland is focused on maintaining flexible operations and actively managing risks for financial resilience while pursuing growth opportunities.

Key tariff exposures (as of April 30th):

Financial Outlook

Ashland is adjusting its full-year fiscal 2025 outlook to reflect a weakening macroeconomic environment that is dampening consumer sentiment and demand globally. This shift is evident in the following key areas:

Ashland now anticipates flattish organic sales volume growth for the full fiscal year. This revision reflects the company’s expectation of a positive inflection in organic sales volumes in the second half, led by Life Sciences, which Ashland anticipates will offset the organic sales volume declines experienced in the first half. Year-over-year pricing headwinds are expected to lessen in the second half of the fiscal year as the company moves beyond comparable periods with prior pricing actions.

Excluding the tariff impact detailed earlier in this press release, overall raw material costs are expected to remain generally stable year-over-year. The outlook reflects Ashland’s assessment of the direct financial impact from global trade policies in the second half of fiscal 2025. In response to this evolving demand landscape, Ashland is proactively focusing on its strategic priorities. The completed portfolio optimization initiative and accelerating cost savings programs are expected to enhance business mix and improve profitability throughout the remainder of the fiscal year.

Based on these factors, Ashland now projects full fiscal year sales in the range of $1.825 billion to $1.9 billion and adjusted EBITDA in the range of $400 million to $420 million.

“Looking ahead, while macroeconomic conditions are challenging with limited visibility, our end-markets generally demonstrate resilience. Operating primarily in consumer-led staple markets provides inherent stability. However, demand trends have been more challenging than anticipated, influenced by the disrupted geopolitical and economic climate, as well as specific customer weaknesses. While tariff uncertainty remains high, we are focused on mitigating downside and capturing upside. To navigate this uncertain environment, we are acting with prudence and discipline, concentrating on our controllable factors to maximize results. Looking to the longer term, our strategic priorities guide our focus. We remain committed to advancing growth catalysts and strengthening the competitive position of our core businesses. We are confident in our long-term fundamentals and portfolio resilience. Ashland is taking decisive actions to navigate near-term challenges effectively and position the company for sustainable growth and enhanced profitability. I look forward to sharing more insight during our earnings call tomorrow morning,” Novo concluded.

Use of Non-GAAP Measures

Ashland believes that by removing the impact of depreciation and amortization and excluding certain non-cash charges, amounts spent on interest and taxes and certain other charges that are highly variable from year to year, EBITDA, Adjusted EBITDA, EBITDA margin and Adjusted EBITDA margin provide Ashland’s investors with performance measures that reflect the impact to operations from trends in changes in sales, margin and operating expenses, providing a perspective not immediately apparent from net income, operating income, net income margin and operating income margin. The adjustments Ashland makes to derive the non-GAAP measures of EBITDA, Adjusted EBITDA, EBITDA margin and Adjusted EBITDA margin exclude items which may cause short-term fluctuations in net income and operating income and which Ashland does not consider to be the fundamental attributes or primary drivers of its business. EBITDA, Adjusted EBITDA, EBITDA margin and Adjusted EBITDA margin provide disclosure on the same basis as that used by Ashland’s management to evaluate financial performance on a consolidated and reportable segment basis and provide consistency in our financial reporting, facilitate internal and external comparisons of Ashland’s historical operating performance and its business units, and provide continuity to investors for comparability purposes. EBITDA margin and Adjusted EBITDA margin are defined as EBITDA and Adjusted EBITDA divided by sales for the corresponding period.

Key items, which are set forth on Table 7 of this release, are defined as financial effects from significant transactions that, either by their nature or amount, have caused short-term fluctuations in net income and/or operating income which Ashland does not consider to reflect Ashland’s underlying business performance and trends most accurately. Further, Ashland believes that providing supplemental information that excludes the financial effects of these items in the financial results will enhance the investor’s ability to compare financial performance between reporting periods.

Tax-specific key items, which are set forth on Table 7 of this release, are defined as financial transactions, tax law changes or other matters that fall within the definition of key items as described above. These items relate solely to tax matters and would only be recorded within the income tax caption of the Statement of Consolidated Income. As with all key items, due to their nature, Ashland does not consider the financial effects of these tax-specific key items on net income to be the most accurate reflection of Ashland’s underlying business performance and trends.

The free cash flow metrics enable Ashland to provide a better indication of the ongoing cash being generated that is ultimately available for both debt and equity holders as well as other investment opportunities. Unlike cash flow provided by operating activities, free cash flow and ongoing free cash flow include the impact of capital expenditures from continuing operations and other significant items impacting free cash flow, providing a more complete picture of current and future cash generation. Free cash flow, ongoing free cash flow, and free cash flow conversion are non-GAAP liquidity measures that Ashland believes provide useful information to management and investors about Ashland’s ability to convert Adjusted EBITDA to ongoing free cash flow. These liquidity measures are used regularly by Ashland’s stakeholders and industry peers to measure the efficiency at providing cash from regular business activity. Free cash flow, ongoing free cash flow, and free cash flow conversion have certain limitations, including that they do not reflect adjustments for certain non-discretionary cash flows such as mandatory debt repayments. The amount of mandatory versus discretionary expenditures can vary significantly between periods.

Adjusted diluted earnings per share is a performance measure used by Ashland and is defined by Ashland as earnings (loss) from continuing operations, adjusted for identified key items and divided by the number of outstanding diluted shares of common stock. Ashland believes this measure provides investors additional insights into operational performance by providing earnings and diluted earnings per share metrics that exclude the effect of the identified key items and tax specific key items.

The Adjusted diluted earnings per share, excluding intangibles amortization expense metric enables Ashland to demonstrate the impact of non-cash intangibles amortization expense on earnings per share, in addition to key items previously mentioned. Ashland’s management believes this presentation is helpful to illustrate how previous acquisitions impact applicable period results.

Ashland does not quantitatively reconcile our guidance ranges for our non-GAAP measures to their most comparable GAAP measures in the Financial Outlook section of this press release. The guidance ranges for GAAP and non-GAAP financial measures reflect Ashland’s assessment of potential sources of variability in financial results and are informed by evaluation of multiple scenarios, many of which have interactive effects across several financial statement line items. Providing guidance for individual reconciling items between our non-GAAP financial measures and the comparable GAAP measures would imply a degree of precision and certainty in those reconciling items that is not a consistent reflection of our scenario-based process to prepare our guidance ranges. To the extent that a material change affecting the individual reconciling items between the Company’s forward-looking non-GAAP and comparable GAAP financial measures is anticipated, the Company has provided qualitative commentary in the Financial Outlook section of this press release for your consideration. However, as the impact of such factors cannot be predicted with a reasonable degree of certainty or precision, a quantitative reconciliation is not available without unreasonable effort.
