How to solve a DuPont analysis example problem?

The magical formula transformation Mathematics features magical formula transformations that help us better understand phenomena. Through such transformations, the disciplines of management and financial management—two seemingly distinct fields—become interconnected and integrable. The magic of this formula transformation lies in decomposing ROE (Return on Equity), an abstract financial concept, into three intuitive metrics: ・Profitability of products—Net Profit Margin ・Asset Turnover ・Financial Leverage ROE is simply the product of these three components. Each term in the formula represents a concrete, easily interpretable financial indicator, enabling immediate identification of where problems lie. Paradoxically, making the formula more complex yields simpler, more intuitive insights. The significance of this approach is to clearly distinguish whether a company’s operational issues stem from low profits, weak sales volume, or excessive (or insufficient) financial leverage. A higher net profit margin indicates stronger product profitability; a higher asset turnover ratio reflects robust sales volume, rapid asset turnover, high asset utilization, and minimal idle assets. This also explains why certain projects—even those operating at a loss—are still pursued: because they accelerate cash flow and sustain healthy working capital cycles. If return on assets (ROA) is low, it is attributable either to a low sales profit margin, a low asset turnover ratio, or both. If the sales profit margin is low, possible causes include pricing too low or excessively high costs. If the asset turnover ratio is low, improvements must be made—e.g., optimizing workflows—to increase turnover. Leverage is a double-edged sword—use it with caution. 3. Performance Decomposition The formula derived from the above decomposition is the renowned DuPont Formula. The diagram below illustrates the underlying logic of DuPont analysis: According to DuPont logic, what enterprises ultimately pursue is ROE. The level of ROE is primarily determined by sales profit margin and capital turnover rate. So how do we improve sales profit margin? Essentially, by increasing revenue and reducing expenses. As Kazuo Inamori put it: "The principle of management is to maximize sales and minimize expenditures." 3.1 Gross Profit Thus emerges a critically important concept: gross profit—a key metric demanding close attention. Definition of gross profit: In commercial accounting, gross profit equals sales revenue minus the direct costs associated with core business operations. Gross profit is not yet the final profit earned, because additional expenses—including selling, R&D, and general administrative costs—must still be deducted. Only after subtracting all such expenses does one arrive at net profit.

III. DuPont’s Past and Present! DuPont (E.I. du Pont de Nemours and Company) is a historic multinational enterprise whose development spans over two centuries—from its origins as a gunpowder manufacturer to its current status as a global leader in science and materials technology. DuPont’s history is not merely the rise and fall of a single corporation; it epitomizes the broader evolution of America’s chemical industry—from traditional manufacturing to high-tech innovation. Key developmental stages are outlined below: 1. Origins and Early Development (1802–1902) Founding Context: In 1802—during China’s Jiaqing era—French immigrant Éleuthère Irénée du Pont founded DuPont in Wilmington, Delaware, initially producing gunpowder. Government contracts—especially during the War of 1812—served as critical early growth drivers. Family-Style Management: For its first century, DuPont operated under strict, quasi-military family control. Henry du Pont consolidated the U.S. gunpowder market via industry alliances and acquisitions; in 1889, he established the U.S. Powder Trade Association, controlling two-thirds of national output. 2. Transformation and Expansion in the 20th Century (1903–2000) Triumvirate Revival: Following Eugene du Pont’s death in 1902, the company faced crisis. Brothers Alfred, Coleman, and Pierre assumed leadership, steering DuPont from a family-run firm toward modern, conglomerate-style management. They acquired 64 companies, secured control over two-thirds of U.S. explosives capacity, and reorganized as E.I. du Pont de Nemours Powder Company. Diversification and Innovation: Booming wartime munitions orders enriched DuPont alongside the U.S. government. Post-war, it pivoted decisively into chemicals. Starting in the 1930s, it launched revolutionary materials—including nylon and Teflon—establishing dominance in polymer chemistry. Later innovations—Kevlar, Tyvek—found wide application across defense, aerospace, and healthcare. Management Reform: From the 1940s onward, DuPont progressively introduced professional managers, diluting family control. Repeated spin-offs and restructuring followed to meet global competition. 3. 21st-Century Spin-offs and Restructuring: Breaking Up to Scale Down (2000–2025) In 1902, DuPont began establishing multiple laboratories dedicated to polymer research—while, at the same time, China’s Qing Dynasty was fleeing to Shaanxi Province after the Eight-Nation Alliance invasion, and later signed the Boxer Protocol before returning to Beijing. DuPont’s strategic focus on polymer materials preceded China’s East University (Dongda) by 80 years. From 1917, DuPont held a 23% stake in General Motors; by 1920, its 27% share gave it de facto control, allowing board dominance until antitrust divestiture in the 1950s. From 1935 onward, DuPont developed nylon, Teflon, and other breakthrough materials—while Dongda was embroiled in civil war and resistance against Japan. Dongda lagged by 70 years. During WWII (1939–1945), DuPont supplied military materials to Boeing, securing special equity stakes that long influenced Boeing’s aerospace materials R&D decisions. In the 1960s, the DuPont and Rockefeller families jointly built a chemical-finance conglomerate—the Chase Manhattan Bank. From the 1980s, DuPont exited basic chemicals and petroleum businesses, focusing instead on specialty chemicals and materials science—whereas Dongda’s petrochemical system had only just begun; Dongda trailed by 80 years. In 1981, DuPont acquired Continental Oil Company (Conoco) for $8 billion, subsequently controlling 12% of U.S. crude oil production through the DuPont-Conoco structure. After 2000, DuPont began spinning off traditional materials businesses and gradually entered nutrition & health, electronic materials, and medical materials—Dongda lagged by 20 years. In 2004, DuPont sold its textile and interior décor business—including nylon and Lycra brands—to Koch Industries (forming Invista) for $4.4 billion in cash. In 2015, DuPont spun off its Teflon and titanium dioxide businesses into Chemours, an independent, publicly traded company. In 2017, DuPont merged with Dow Chemical to form DowDuPont, later unwound due to antitrust concerns and strategic realignment. In 2019, DowDuPont split into three independent entities: • Dow: Focused on materials science (plastics, coatings, etc.), market cap >$20 billion. • Corteva Agriscience: Specializing in agricultural technologies (seeds, pesticides), now an independent public company with market cap >$40 billion. • New DuPont: Operating specialty products (electronic materials, medical devices, etc.), market cap >$25 billion. In 2021, DuPont divested its Nutrition & Biosciences business to International Flavors & Fragrances (IFF) for $7.3 billion. In 2022, DuPont sold most of its Mobility & Materials (M&M) division—primarily engineering plastics—to Celanese for $11 billion. In 2023, DuPont sold 80.1% of its Delrin homopolymer POM business to TJC LP for $1.8 billion—representing ~80% of the global homopolymer POM market. In 2024, DuPont announced plans to spin off its Electronics business (semiconductor technologies, interconnect solutions) into a standalone public company, targeting completion in 2025. Meanwhile, over the past two decades, Dongda has systematically revived its entire chemical materials industrial chain—covering all categories—effectively replicating the 80-year trajectory pioneered by DuPont and other U.S. chemical giants. By the first half of 2025, Dongda’s high-end materials sector has experienced explosive growth, achieving near-total domestic substitution. The trade conflict has evolved from earlier agriculture-focused tariffs to today’s across-the-board 34% blanket tariffs—highlighting the extraordinary intensity and strategic weight of Dongda’s five-year sprint. Setting aside national boundaries, although Dongda’s chemical and materials industry has rapidly closed the gap over the past two decades, it still needs to draw upon DuPont’s experience in fundamental research, industrial upgrading, and global competition—ultimately transforming China from a manufacturing powerhouse into an innovation-driven nation.
