Investor DayMay 1, 2017, New York City  Ashland’s Strategy and Commitment to Create Shareholder Value 2018-2021 

   Forward-Looking StatementsThis presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. Ashland has identified some of these forward-looking statements with words such as “anticipates,” “believes,” “expects,” “estimates,” “is likely,” “predicts,” “projects,” “forecasts,” “objectives,” “may,” “will,” “should,” “plans” and “intends” and the negative of these words or other comparable terminology. These forward-looking statements include statements relating to our expectation that the proposed acquisition of Pharmachem Laboratories, Inc. (Pharmachem) will be completed before the end of the June quarter and that the proposed acquisition will be accretive to earnings per share, and the expected completion of the separation of Valvoline Inc. (“Valvoline”) through the distribution of Valvoline common stock. In addition, Ashland may from time to time make forward-looking statements in its annual reports, quarterly reports and other filings with the SEC, news releases and other written and oral communications. These forward-looking statements are based on Ashland’s expectations and assumptions, as of the date such statements are made, regarding Ashland’s future operating performance and financial condition, the expected completion of the final separation of Valvoline, the strategic and competitive advantages of each company, and future opportunities for each company, as well as the economy and other future events or circumstances. Ashland’s expectations and assumptions include, without limitation, internal forecasts and analyses of current and future market conditions and trends, management plans and strategies, operating efficiencies and economic conditions (such as prices, supply and demand, cost of raw materials, and the ability to recover raw-material cost increases through price increases), and risks and uncertainties associated with the following: Ashland’s substantial indebtedness (including the possibility that such indebtedness and related restrictive covenants may adversely affect Ashland’s future cash flows, results of operations, financial condition and its ability to repay debt); the impact of acquisitions and/or divestitures Ashland has made or may make, including the proposed acquisition of Pharmachem (including the possibility that Ashland may not complete the proposed acquisition of Pharmachem or Ashland may not realize the anticipated benefits from such transactions); and severe weather, natural disasters, and legal proceedings and claims (including environmental and asbestos matters). Various risks and uncertainties may cause actual results to differ materially from those stated, projected or implied by any forward-looking statements, including, without limitation, risks and uncertainties affecting Ashland that are described in Ashland’s most recent Form 10-K (including Item 1A Risk Factors) filed with the SEC, which is available on Ashland’s website at http://investor.ashland.com or on the SEC’s website at http://www.sec.gov. Ashland believes its expectations and assumptions are reasonable, but there can be no assurance that the expectations reflected herein will be achieved. Unless legally required, Ashland undertakes no obligation to update any forward-looking statements made in this presentation whether as a result of new information, future events or otherwise. Information on Ashland’s website is not incorporated into or a part of this presentation.Regulation G: Adjusted ResultsThe information presented herein regarding certain unaudited adjusted results does not conform to generally accepted accounting principles in the United States (U.S. GAAP) and should not be construed as an alternative to the reported results determined in accordance with U.S. GAAP. Ashland has included this non-GAAP information to assist in understanding the operating performance of the company and its reportable segments. The non-GAAP information provided may not be consistent with the methodologies used by other companies. All non-GAAP information related to previous Ashland filings with the SEC has been reconciled with reported U.S. GAAP results. Although Ashland provides forward-looking guidance for adjusted EBITDA, Ashland is not reaffirming or providing forward-looking guidance for U.S. GAAP-reported financial measures or a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable U.S. GAAP measure because it is unable to predict with reasonable certainty the ultimate outcome of certain significant items without unreasonable effort.  Note: This presentation contains a more detailed profile than we have reported in the past, or will report regularly in the future.  1

 Examples: Better Asset Utilization 

   CMC utilization  2017 YTD  2016  2015  2014  +18%  After a fall off in the energy market utilization at the Jiangmen facility fell by 12%  CMC utilization in Jiangmen rebounded in 2017...  Decreased production volume would increase per unit fixed cost burden by ~15% from 2014-16To address the per unit increases, sales, marketing, manufacturing, and supply chain teams identified two new ways to go to marketsGo 'smaller' to address tier 2 nutrition manufacturersAddress the 'lower spec', higher volume applications—paper coatings and miningThe two pronged approach has driven a full recovery in utilization. Driving per unit fixed costs below their 2014 low  ...thanks to targeted sales and marketing efforts to 'fill the plant'  Back  Lower cost-per-unit in Jiangmen 

   Back  Freetown plant successfully completed the 2nd commercial batch trial of Flexcryl 1624Once approved, plant will able to supply 400-450MT/month of material to support business growthRepurposed equipment in Freetown will successfully reduce the need for $5MM of CapEx at the Piedmont plant  Freetown plant repurposed to reduce need for CapEx
