DuPont Exercises Option to Acquire OxyMem

WILMINGTON, Del., Dec. 18, 2019 – DuPont (NYSE: DD) today announced it has exercised its option to acquire full ownership of OxyMem Limited, a company that develops and produces Membrane Aerated Biofilm Reactor (MABR) technology for the treatment and purification of municipal and industrial wastewater. OxyMem has more than 60 employees and one production site located in Athlone, Ireland. The transaction will close before Dec. 31, 2019.

OxyMem was founded in 2013, based on a technology spin-out from the University College Dublin, Ireland. The company is engaged in the development, manufacturing and sales of MABR units using patented technology for hollow fiber, silicone polydimethylsiloxane (PDMS) membranes to treat wastewater. DuPont already owns 31 percent of the company and has exercised its option to acquire all outstanding shares of OxyMem for 100 percent ownership.

“MABR is a new technology that offers unique and differentiated performance for secondary wastewater treatment over existing technologies,” said HP Nanda, Global Vice President and General Manager, DuPont Water Solutions. “Wastewater is a fast-growing global market driven by industrial expansion, challenging water conditions and tightening regulations. Together with the MEMCOR MBR product DuPont is acquiring, this additional emerging technology provides more solutions for customers looking to reduce footprint and energy requirements for secondary wastewater treatment and enhances the performance of systems using other traditional water purification, reuse and recovery technologies.”

“OxyMem has benefited from working with DuPont, as an investor, for the last four years. A world-class water business, DuPont helped us refocus our development efforts to advance our Membrane Aerated Biofilm Reactor (MABR) technology,” said Wayne Byrne, CEO OxyMem Limited. “With the ownership of DuPont, we look forward to scaling MABR to meet the growing demand for the treatment and purification of municipal and industrial wastewater.”

DuPont is a leader in water purification and separation technology including ultrafiltration, reverse osmosis and ion exchange resins. The FilmTec™ brand is recognized globally and known for consistent and reliable performance. Each of the acquisitions announced this year supports our strategy to drive growth and innovation through access to new manufacturing capabilities, geographies and technologies.

Forward-looking statements address matters that are, to varying degrees, uncertain and subject to risks, uncertainties and assumptions, many of which that are beyond DuPont's control, that could cause actual results to differ materially from those expressed in any forward-looking statements. Forward-looking statements are not guarantees of future results. Some of the important factors that could cause DuPont's actual results to differ materially from those projected in any such forward-looking statements include, but are not limited to: (i) ability and costs to achieve all the expected benefits from the Dow Distribution and the Corteva Distribution (together, the “Distributions”); (ii) restrictions under intellectual property cross license agreements entered into in connection with the Distributions; (iii) non-compete restrictions agreed in connection with the Distributions; (iv) the incurrence of significant costs in connection with the Distributions, including costs to service debt incurred by the Company to establish the relative credit profiles of Corteva, Dow and DuPont and increased costs related to supply, service and other arrangements that, prior to the Dow Distribution, were between entities under the common control of DuPont; (v) risks related to indemnification of certain legacy liabilities of E. I. du Pont de Nemours and Company ("Historical EID") in connection with the Corteva Distribution; (vi) potential liability arising from fraudulent conveyance and similar laws in connection with the Distributions; (vii) failure to effectively manage acquisitions, divestitures, alliances, joint ventures and other portfolio changes, including meeting conditions under the Letter Agreement entered in connection with the Corteva Distribution, related to the transfer of certain levels of assets and businesses; (viii) uncertainty as to the long-term value of DuPont common stock; (ix) potential inability or reduced access to the capital markets or increased cost of borrowings, including as a result of a credit rating downgrade and (x) other risks to DuPont's business, operations and results of operations including from: failure to develop and market new products and optimally manage product life cycles; ability, cost and impact on business operations, including the supply chain, of responding to changes in market acceptance, rules, regulations and policies and failure to respond to such changes; outcome of significant litigation, environmental matters and other commitments and contingencies; failure to appropriately manage process safety and product stewardship issues; global economic and capital market conditions, including the continued availability of capital and financing, as well as inflation, interest and currency exchange rates; changes in political conditions, including tariffs, trade disputes and retaliatory actions; impairment of goodwill or intangible assets; the availability of and fluctuations in the cost of energy and raw materials; business or supply disruption, including in connection with the Distributions; security threats, such as acts of sabotage, terrorism or war, natural disasters and weather events and patterns which could result in a significant operational event for DuPont, adversely impact demand or production; ability to discover, develop and protect new technologies and to protect and enforce DuPont's intellectual property rights; unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as management's response to any of the aforementioned factors. These risks are and will be more fully discussed in DuPont's current, quarterly and annual reports and other filings made with the U.S. Securities and Exchange Commission, in each case, as may be amended from time to time in future filings with the SEC. While the list of factors presented here is considered representative, no such list should be considered a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on DuPont’s consolidated financial condition, results of operations, credit rating or liquidity. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. DuPont assumes no obligation to publicly provide revisions or updates to any forward-looking statements whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws. A detailed discussion of some of the significant risks and uncertainties which may cause results and events to differ materially from such forward-looking statements is included in the section titled “Risk Factors” (Part II, Item 1A) of DuPont’s Quarterly Report on Form 10-Q filed on October 31, 2019 as may be modified by DuPont's subsequent quarterly reports on Form 10-Q and current reports on Form 8-K.
