This Annual Report on Form 10-K is a combined report being filed by Dow Inc. and The Dow Chemical Company and its consolidated subsidiaries (“TDCC” and together with Dow Inc., “Dow” or the "Company"). This Annual Report on Form 10-K reflects the results of Dow and its consolidated subsidiaries, after giving effect to the distribution to DowDuPont Inc. (“DowDuPont” and effective June 3, 2019, n/k/a DuPont de Nemours, Inc. or "DuPont") of TDCC’s agricultural sciences business (“AgCo”) and specialty products business (“SpecCo”) and the receipt of E. I. du Pont de Nemours and Company and its consolidated subsidiaries' (“Historical DuPont”) ethylene and ethylene copolymers business (other than its ethylene acrylic elastomers business) ("ECP"). The U.S. GAAP consolidated financial results of Dow Inc. and TDCC reflect the distribution of AgCo and SpecCo as discontinued operations for the applicable periods presented as well as the receipt of ECP as a common control transaction from the closing of the merger with Historical DuPont on August 31, 2017. In addition, following the separation from DowDuPont, the Company changed the manner in which its business activities were managed. The Company's portfolio now includes six global businesses which are organized into the following operating segments: Packaging & Specialty Plastics, Industrial Intermediates & Infrastructure and Performance Materials & Coatings. Corporate contains the reconciliation between the totals for the operating segments and the Company's totals. As a result of the parent/subsidiary relationship between Dow Inc. and TDCC, and the expectation that the financial statements and disclosures of each company will be substantially similar, the companies are filing a combined report for this Annual Report on Form 10-K. The information reflected in this report is equally applicable to both Dow Inc. and TDCC, except where otherwise noted. Each of Dow Inc. and TDCC is filing information in this report on its own behalf and neither company makes any representation to the information relating to the other company.
Background
On April 1, 2019, DowDuPont completed the separation of its materials science business and Dow Inc. became the direct parent company of TDCC and its consolidated subsidiaries, owning all of the outstanding common shares of TDCC. For filings relating to the period commencing April 1, 2019 and thereafter, TDCC was deemed the predecessor to Dow Inc., and the historical results of TDCC are deemed the historical results of Dow Inc. for periods prior to and including March 31, 2019.
The separation was contemplated by the merger of equals transaction effective August 31, 2017, under the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017. TDCC and Historical DuPont each merged with subsidiaries of DowDuPont and, as a result, TDCC and Historical DuPont became subsidiaries of DowDuPont (the “Merger”). Subsequent to the Merger, TDCC and Historical DuPont engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products. Dow Inc. was formed as a wholly owned subsidiary of DowDuPont to serve as the holding company for the materials science business.

ITEM 1. BUSINESS
THE COMPANY
Dow Inc. was incorporated on August 30, 2018, under Delaware law, to serve as a holding company for The Dow Chemical Company and its consolidated subsidiaries ("TDCC" and together with Dow Inc., "Dow" or the "Company"). Dow Inc. operates all of its businesses through TDCC, a wholly owned subsidiary, which was incorporated in 1947 under Delaware law and is the successor to a Michigan corporation, of the same name, organized in 1897. The Company's principal executive offices are located at 2211 H.H. Dow Way, Midland, Michigan 48674.
Available Information
The Company's Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, are available free of charge at www.dow.com/investors, as soon as reasonably practicable after the reports are electronically filed or furnished with the U.S. Securities and Exchange Commission ("SEC"). The SEC maintains a website that contains these reports as well as proxy statements and other information regarding issuers that file electronically. The SEC's website is at www.sec.gov. Dow's website and its content are not deemed incorporated by reference into this report.
MERGER AND SEPARATION
On April 1, 2019, DowDuPont Inc. (“DowDuPont” and effective June 3, 2019, n/k/a DuPont de Nemours, Inc. or "DuPont") completed the separation of its materials science business and Dow Inc. became the direct parent company of TDCC and its consolidated subsidiaries, owning all of the outstanding common shares of TDCC.
The separation was contemplated by the merger of equals transaction effective August 31, 2017, under the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017. TDCC and E. I. du Pont de Nemours and Company and its consolidated subsidiaries (“Historical DuPont”) each merged with subsidiaries of DowDuPont and, as a result, TDCC and Historical DuPont became subsidiaries of DowDuPont (the “Merger”). Subsequent to the Merger, TDCC and Historical DuPont engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products. Dow Inc. was formed as a wholly owned subsidiary of DowDuPont to serve as the holding company for the materials science business.
As of the effective date and time of the distribution, DowDuPont does not beneficially own any equity interest in Dow and no longer consolidates Dow and its consolidated subsidiaries into its financial results. The consolidated financial results of Dow for periods prior to April 1, 2019, reflect the distribution of TDCC’s agricultural sciences business (“AgCo”) and specialty products business (“SpecCo”) as discontinued operations for each period presented as well as reflect the receipt of Historical DuPont’s ethylene and ethylene copolymers businesses (other than its ethylene acrylic elastomers business) (“ECP”) as a common control transaction from the closing of the Merger on August 31, 2017. See Notes 3 and 4 to the Consolidated Financial Statements and Dow Inc.'s Amendment No. 4 to the Registration Statement on Form 10 filed with the SEC on March 8, 2019, for additional information.
Throughout this Annual Report on Form 10-K, unless otherwise indicated, amounts and activity are presented on a continuing operations basis.
About Dow
Dow combines global breadth, asset integration and scale, focused innovation and leading business positions to achieve profitable growth. The Company’s ambition is to become the most innovative, customer centric, inclusive and sustainable materials science company. Dow’s portfolio of plastics, industrial intermediates, coatings and silicones businesses delivers a broad range of differentiated science-based products and solutions for its customers in high-growth market segments, such as packaging, infrastructure and consumer care. Dow operates 109 manufacturing sites in 31 countries and employs approximately 36,500 people.
BUSINESS SEGMENTS AND PRODUCTS
Effective with the Merger, TDCC's business activities were components of DowDuPont's business operations and were reported as a single operating segment. Following the separation from DowDuPont, the Company changed the manner in which its business activities were managed. The Company's portfolio now includes six global businesses which are organized into the following operating segments: Packaging & Specialty Plastics, Industrial Intermediates & Infrastructure and Performance Materials & Coatings. Corporate contains the reconciliation between the totals for the operating segments and the Company's totals. The Company did not aggregate any operating segments when determining its reportable segments. See Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations and Note 27 to the Consolidated Financial Statements for additional information concerning the Company’s operating segments.
PACKAGING & SPECIALTY PLASTICS
Packaging & Specialty Plastics consists of two highly integrated global businesses: Hydrocarbons & Energy and Packaging and Specialty Plastics. The segment employs the industry’s broadest polyolefin product portfolio, supported by the Company’s proprietary catalyst and manufacturing process technologies, to work at the customer’s design table throughout the value chain to deliver more reliable and durable, higher performing, and more sustainable plastics to customers in food and specialty packaging; industrial and consumer packaging; health and hygiene; caps, closures and pipe applications; consumer durables; automotive; and infrastructure.
The Company’s unique advantages compared with its competitors include: extensive low-cost feedstock positions around the world; unparalleled scale, global footprint and market reach, with world-class manufacturing sites in every geography; deep customer and brand owner understanding; portfolio of higher-value functional polymers, such as polyolefin elastomers, semiconductive and jacketing compound solutions and wire and cable insulation; and market-driven application development and technical support.
The segment remains agile and adaptive by participating in the entire ethylene-to-polyethylene chain integration, enabling the Company to manage market swings, and therefore optimize returns while reducing long-term earnings volatility. The Company’s unrivaled value chain ownership is further strengthened by its Pack Studio locations in every geography, which help customers and brand owners deliver faster and more efficient packaging product commercialization through a global network of laboratories, technical experts and testing equipment.
Hydrocarbons & Energy
Hydrocarbons & Energy is the largest global producer of ethylene, a key chemical building block that the Company consumes primarily within the Packaging & Specialty Plastics segment. Ethylene is transferred to downstream derivative businesses at market-based prices, which are generally equivalent to prevailing market prices for large volume purchases. In addition to ethylene, the business is a leading producer of propylene and aromatics products that are used to manufacture materials that consumers use every day. The business also produces and procures the power and feedstocks used by the Company’s manufacturing sites.
Packaging and Specialty Plastics
Packaging and Specialty Plastics serves growing, high-value sectors using world-class technology, broad existing product lines, and a rich product pipeline that creates competitive advantages for the entire packaging value chain. The business is a recognized leader in the production, marketing and innovation of polyethylene. The business is also a leader in other ethylene derivatives, such as polyolefin elastomers, ethylene vinyl acetate and ethylene propylene diene monomer ("EPDM") rubber serving automotive, consumer, wire and cable and construction markets. Market growth is expected to be driven by major shifts in population demographics; improving socioeconomic status in emerging geographies; consumer and brand owner demand for increased functionality; global efforts to reduce food waste; growth in telecommunications networks; global development of electrical transmission and distribution infrastructure; and renewable energy applications.
Divestiture
On September 1, 2017, the Company sold its global Ethylene Acrylic Acid copolymers and ionomers business to SK Global Chemical Co., Ltd. See Note 6 to the Consolidated Financial Statements for additional information.
Details on Packaging & Specialty Plastics' 2019 net sales, by business and geographic region, are as follows:

Current and Future Investments
In 2017, the Company announced the startup of its new integrated world-scale ethylene production facility and its new ELITE™ Enhanced Polyethylene production facility, both located in Freeport, Texas. In 2018, the Company started up its new LDPE production facility and its new NORDEL™ Metallocene EPDM production facility, both located in Plaquemine, Louisiana. These key milestones enable the Company to capture benefits from increasing supplies of U.S. shale gas to deliver differentiated downstream solutions in its core market verticals. The Company also completed debottlenecking of an existing bi-modal gas phase polyethylene production facility in St. Charles, Louisiana, and started up a new High Melt Index ("HMI") AFFINITY™ polymer production facility in Freeport, Texas, in the fourth quarter of 2018.
Additionally, the Company has announced investments over the next five years that are expected to enhance competitiveness. These include:
| |
• | Expansion of the capacity of the Company’s new ethylene production facility in Freeport, TX, bringing the facility’s total ethylene capacity to 2,000 kilotonnes per annum ("KTA") and making it the largest ethylene cracker in the world. |
| |
• | Incremental debottleneck projects across its global asset network that will deliver approximately 350 KTA of additional polyethylene, the majority of which will be in U.S. & Canada. |
| |
• | Construction of a world-scale polyethylene unit on the U.S. Gulf Coast based on Dow’s proprietary process technologies, to meet consumer-driven demand in specialty packaging, health and hygiene, and industrial and consumer packaging applications. |
| |
• | A new catalyst production facility for key catalysts licensed by Univation Technologies, LLC, a wholly owned subsidiary of the Company. |
| |
• | On January 29, 2020, the Company announced plans to add another furnace to its ethylene production facility in Alberta, Canada, incrementally expanding capacity by approximately 130,000 metric tons. Dow will co-invest in the expansion with a regional customer, evenly sharing project costs and ethylene output, with the additional ethylene to be consumed by existing polyethylene manufacturing assets in the region. The expansion is expected to come online in the first half of 2021. |
The Company's ambition includes becoming the most sustainable materials science company in the world with a strategy to advance the well-being of humanity by helping lead the transition to a sustainable planet and society. This includes lowering energy and greenhouse gas emissions ("GHG") and enabling a shift to a circular economy for plastics by focusing on resource efficiency and integrating recycled content and renewable feedstocks into its production processes. As part of that strategy, Dow announced the following in August 2019:
| |
• | An agreement with the Fuenix Ecogy Group, based in Weert, The Netherlands, for the supply of pyrolysis oil feedstock, which is made from recycled plastic waste. The feedstock will be used to produce virgin polymers at Dow’s production facilities in Terneuzen, The Netherlands. This is an important step forward to increase feedstock recycling - the process of breaking down mixed waste plastics into their original form to manufacture new virgin polymers. The polymers produced from this pyrolysis oil will be identical to products produced from traditional feedstocks, and as such, they can be used in the same applications, including food packaging. |
| |
• | An agreement with UPM Biofuels, a producer of biofuels, for the supply and integration of wood-based UPM Bio Verno renewable naphtha - a key raw material used to develop plastics - into Dow's slate of raw materials, creating an alternative source for plastics production. The feedstock will be used to produce bio-based polyethylene at Dow's production facilities in Terneuzen, The Netherlands, for use in packaging applications such as food packaging, to reduce food waste. |
| |
• | The retrofit of one of its Louisiana steam crackers with Dow’s proprietary fluidized catalytic dehydrogenation ("FCDh") technology to produce on-purpose propylene. The FCDh technology retrofit further improves Dow’s ability to continue to source the most advantaged feedstocks, while also producing reliable and cost-efficient on-purpose propylene to supply its integrated derivative units in Louisiana. The technology reduces capital outlay by up to 25 percent and lowers energy usage and GHG by up to 20 percent, thereby improving overall sustainability when compared with conventional propane dehydrogenation technologies. The project is expected to begin producing on-purpose propylene by the end of 2021. |
