Corporate Case Study | June 11, 2026
In 1958, Dhirubhai Ambani returned to Mumbai from Aden with a modest capital and a trading idea. He began selling polyester yarn and spices. By 1977, his company was listed on the stock exchange and had introduced equity investing to millions of ordinary Indians who had never owned a share before. By 1999, he had built the world’s largest grassroots oil refinery at Jamnagar, Gujarat. By 2016, his son Mukesh launched Jio and reset the economics of telecom not just in India but globally. By April 2026, Reliance Industries became the first Indian company to cross USD 10 billion in annual net profit, with FY26 revenues of Rs 11.75 lakh crore, EBITDA of Rs 2.07 lakh crore, and a registered Jio subscriber base approaching 500 million. This case study traces the full arc of that journey, from textile trading to the world’s most complex single-site refinery, from a bitter inheritance dispute to one of the most consequential business transformations in Asia, and from a fossil-fuel conglomerate to a company now staking Rs 5 lakh crore on the energy transition.

Part IThe Founder and the First Three Decades (1958 to 1990)
Dhirajlal Hirachand Ambani: Origins and Ambition
Dhirajlal Hirachand Ambani, known universally as Dhirubhai, was born on December 28, 1932, in Chorwad, a small coastal village in Gujarat’s Junagadh district, into a lower-middle-class schoolteacher’s family. He left school early and, unable to find sufficient opportunity in India, sailed to Aden (present-day Yemen) as a teenager where he worked as a clerk and petrol pump attendant at the A. Besse and Company trading house, gaining his first understanding of commodity markets and cross-border commerce. He returned to Mumbai in 1958 with savings and a commercial instinct shaped by years in a trading entrepot, and established Reliance Commercial Corporation, a firm trading in polyester yarn and spices.
What distinguished Dhirubhai from countless other commodity traders in 1950s Bombay was not initial capital, which was modest, but a specific understanding of India’s License Raj and an exceptional ability to navigate it. The import and export of synthetic fibres was tightly controlled by the government, with licences determining who could trade and at what margins. Dhirubhai identified early that obtaining and deploying export licences in textiles, and then recycling the foreign exchange proceeds to import raw materials, created profit margins unavailable to purely domestic traders. He built relationships across the trading ecosystem, the bureaucracy, and the banking system with a consistency and persistence that later became the subject of both admiration and controversy.
The equity cult Dhirubhai created in India: When Reliance Textile Industries went public in 1977, Dhirubhai Ambani did something that had no precedent in Indian corporate history: he actively recruited retail investors from across Gujarat and Maharashtra, holding investor meetings in small towns and explaining equity returns in the same terms he used to explain commodity returns. The 1977 IPO attracted over 58,000 shareholders, a number unprecedented for an Indian textile company at the time. By the mid-1980s, Reliance annual general meetings at the Brabourne Stadium in Mumbai drew over 30,000 shareholders who travelled from across India, making the AGM a spectacle with no parallel in Indian corporate life. Dhirubhai’s democratisation of equity investing created a generation of retail investors in western India who understood shares as a genuine wealth-building tool, a cultural shift whose effects are still visible in India’s household savings composition.
The Naroda Mill and the Vimal Brand
Reliance Textile Industries was formally incorporated in 1966 in Maharashtra. In 1966, the company set up its first textile manufacturing plant at Naroda, near Ahmedabad, Gujarat. The plant produced synthetic fabrics, and the Vimal brand was formally launched in 1975, becoming within a few years one of the most recognisable textile brands in India. The Vimal brand’s success was built on a combination of superior product quality at accessible price points and an aggressive pan-India distribution network that Dhirubhai built by treating fabric dealers as partners rather than mere distributors, giving them working capital support, marketing assistance, and margin guarantees that incumbents did not offer. Within a decade of the Naroda mill’s establishment, Reliance had become one of India’s largest polyester fabric manufacturers.
Backward Integration into Petrochemicals
Dhirubhai’s defining strategic instinct was backward integration. If Reliance was selling polyester fabric, it needed polyester yarn. If it needed polyester yarn, it needed purified terephthalic acid (PTA). If it needed PTA, it needed paraxylene. If it needed paraxylene, it needed naphtha. If it needed naphtha, it needed crude oil. This chain of reasoning led, over fifteen years, from a textile trading firm to a fully integrated petrochemical and refining company. In 1986, Reliance commissioned its first PTA plant at Patalganga near Mumbai, the first step beyond textiles into chemicals. By 1988, a paraxylene plant had followed. In 1992, high-density polyethylene production started at the Hazira complex in Gujarat. Each new plant deepened the integration that would culminate in the Jamnagar complex of the late 1990s.
The 1985 and 1986 period was also significant for a different reason: Dhirubhai suffered his first stroke in 1986, which partially incapacitated him and led to his sons Mukesh and Anil taking over day-to-day management. The stroke accelerated the transition of executive responsibility downward, even as Dhirubhai remained the strategic chairman and guiding force until his death. Mukesh, who had enrolled in the MBA programme at Stanford University before returning to India in 1980 to join Reliance without completing the degree, took charge of the petrochemical and manufacturing expansion. Anil managed finance and investor relations. The division of responsibilities that the stroke forced would, eighteen years later, become the template for a much more formal and bitter division of the empire itself.
Part IIThe Jamnagar Gamble and the Petrochemical Empire (1991 to 2002)
The Decision to Build the World’s Largest Refinery
The most consequential single investment decision in Reliance Industries’ history was made in the early 1990s: to build a grassroots oil refinery at Jamnagar on the Gujarat coast. The site had been chosen for its deep natural draught, its proximity to the Gulf of Kutch shipping lanes, and the availability of land in a state whose government was broadly supportive of industrial investment. The refinery was designed from the outset not for domestic fuel supply but for export: its configuration prioritised high-value transportation fuels meeting Euro-grade specifications for the US and European markets, a design choice that would make it the most commercially flexible refining facility ever built in an emerging economy.
Construction began in 1996 and was completed in record time. The Jamnagar Refinery Phase 1 was commissioned on July 14, 1999, with an installed capacity of 668,000 barrels per day, at the time the largest single refinery complex ever built at one location from scratch. Bechtel, the US engineering and construction firm, has described its completion as an engineering record. In December 2008, Reliance Petroleum Limited commissioned a second, adjacent refinery inside a Special Economic Zone at Jamnagar, adding a further 580,000 barrels per day and taking the combined throughput to 1.24 million barrels per day, making Jamnagar the world’s largest refining hub at a single location. Today, the combined Jamnagar complex processes 1.4 million barrels per day with a complexity index of 21.1, the highest of any refinery in the world, enabling it to process over 216 different grades of crude oil.
Why complexity index matters: A refinery’s Nelson Complexity Index measures its ability to convert lower-quality, cheaper crude oil feedstocks into higher-value products such as gasoline, diesel, jet fuel, and petrochemical feedstocks. A simple refinery (complexity 1 to 5) can only process light sweet crude and produces a limited product slate. Jamnagar’s complexity of 21.1 means it can profitably process almost any crude oil available in the global market, from light sweet grades to heavy sour varieties, and extract maximum value from every barrel. This flexibility gives Reliance a structural cost advantage over less complex refineries globally: when light crude prices spike relative to heavy crude, Jamnagar switches its feedstock mix. When chemical margins are stronger than fuel margins, it shifts output. No other single-site refinery in the world offers this range.
KG-D6: The Largest Gas Discovery of 2002
In 2002, Reliance announced the discovery of natural gas in the D6 block of the Krishna-Godavari Basin off India’s eastern coast, in the Bay of Bengal. The KG-D6 discovery was confirmed as the largest natural gas deposit ever found in India and was, at the time of discovery, the largest natural gas discovery in the world in 2002. Gas production from KG-D6 began in April 2009, initially at 40 million standard cubic metres per day, with expectations of ramp-up to 80 mmscmd. The field supplied gas to fertiliser companies, power plants, and city gas distribution networks, reducing India’s import dependence on LNG.
KG-D6 production declined sharply from its 2010 peak due to reservoir complexity, water ingress, and technical challenges that created a significant political and regulatory dispute between Reliance and the government over cost recovery, gas pricing, and operational decisions. Production fell from a peak of approximately 61 mmscmd in 2010 to below 10 mmscmd by 2014, triggering a prolonged period of litigation, regulatory scrutiny, and reputational damage for RIL’s upstream business. The field has since been revitalised through new satellite developments. The MJ field, a new deep-water discovery adjacent to KG-D6, commenced production in 2023 and has progressively restored KG basin volumes, restoring Reliance’s upstream credentials.

Part IIIThe Split, the Succession, and the Rebuilding (2002 to 2015)
The Absence of a Will and the Public Feud
When Dhirubhai Ambani died on July 6, 2002 in Mumbai, he left no will. He was 69 years old. The absence of formal succession planning created an immediate governance vacuum in one of India’s largest companies. Mukesh Ambani, the elder son, became Chairman and Managing Director. Anil Ambani became Vice-Chairman. For approximately two years, the brothers attempted to function as joint leaders. The arrangement broke down comprehensively. In November 2004, Mukesh Ambani acknowledged in a press interview that differences existed between the brothers over ownership and control, describing them as being in the “private domain.” What followed was anything but private.
The dispute became public through competing claims over operational control, filings before company law authorities, and widely reported conflicts over the management of specific businesses. It was Dhirubhai’s widow, Kokilaben Ambani, who eventually mediated a settlement. On June 18, 2005, the formal separation was announced. Mukesh retained Reliance Industries Limited with its core businesses: petroleum refining and marketing, petrochemicals, oil and gas exploration and production, and textiles. Anil formed the Reliance Anil Dhirubhai Ambani Group, taking control of telecommunications through Reliance Communications, financial services through Reliance Capital, power generation through Reliance Power, and entertainment through Reliance MediaWorks. A non-compete agreement barred Mukesh from entering the telecom sector for a period.
The divergent fates of the two groups post-2005: The Mukesh-Anil split is one of the most studied succession failures in Asian corporate history. The two brothers’ businesses took starkly different trajectories over the fifteen years that followed. Mukesh built Reliance Industries into India’s largest company, with revenues crossing Rs 10 lakh crore and a market capitalisation reaching Rs 18 lakh crore by 2026. Anil’s Reliance ADA Group accumulated large debts across its telecom, power, and infrastructure businesses, failed to compete with Jio after the non-compete was amended and Mukesh re-entered telecom, and eventually contracted dramatically. In February 2020, Anil Ambani declared in a London court that his personal net worth was zero. The contrast between the two brothers’ fortunes within fifteen years of their father’s death represents one of the starkest post-succession divergences in the history of any business family.
Mukesh’s Decade of Consolidation
Between 2005 and 2015, Mukesh Ambani ran Reliance Industries as a focused energy and petrochemical company. The Jamnagar complex was further expanded, KG-D6 was brought to peak production and then managed through its decline, and the company generated large cash flows from its refining and chemical businesses that it systematically accumulated rather than aggressively deploying. The non-compete agreement, which barred Mukesh from telecom until it was mutually amended in 2010, was a constraint that simultaneously limited RIL’s expansion options and forced a period of financial discipline that resulted in one of the strongest balance sheets among Indian corporates.
In 2010, the non-compete was amended by mutual agreement between the brothers. Almost immediately, Reliance began building the infrastructure for what would become Jio. The 4G spectrum acquired in 2010 and 2012, the fibre infrastructure built across India between 2012 and 2015, and the device ecosystem engineered to make smartphones affordable at scale were all part of a preparation phase that lasted six years and cost billions of dollars before Jio served a single paying customer. This patience, building an infrastructure nobody could see on the balance sheet for years, was characteristic of how Mukesh Ambani ran the company he had inherited.
Part IVThe Jio Disruption: How One Company Reset Indian Telecom (2016 to 2020)
The Launch and Its Immediate Impact
On September 5, 2016, Mukesh Ambani stood up at Reliance Industries’ Annual General Meeting and announced the commercial launch of Jio. Voice calls were free for all customers on any network. 4G data was free. The initial Welcome Offer provided free services until December 31, 2016, followed by an extended Happy New Year Offer that kept data effectively free through March 31, 2017, before paid tariffs came into effect on April 1, 2017. The announcement was not merely a product launch. It was a deliberate, strategically timed attack on the unit economics of every existing telecom operator in India.
The existing incumbents, specifically Airtel, Vodafone, and Idea, had been charging between Rs 200 and Rs 300 per gigabyte of mobile data. Jio’s paid tariffs, when they came into effect on April 1, 2017, were set at approximately Rs 10 per gigabyte, an 80 to 90 percent reduction. The consequences were immediate and irreversible. Voice calling in India became permanently free across all networks, because no operator could charge for voice while Jio was giving it free. Data prices collapsed to among the lowest in the world, averaging approximately Rs 9 to 10 per GB, and have never recovered for the incumbents. Vodafone and Idea, unable to fund the capital expenditure required to compete with Jio’s 4G network at these economics, merged in 2018 to form Vi. Reliance Communications, Anil Ambani’s telecom company, declared insolvency in 2019.
What Jio cost and what it changed: RIL invested approximately Rs 2.5 lakh crore (approximately $35 billion) in building Jio’s 4G network, spectrum, fibre backbone, devices, and content ecosystem before its launch. In the first two years of operation, Jio ran at losses due to its free and then ultra-low-cost pricing. The investment was financed entirely from RIL’s oil and petrochemical cash flows, a cross-subsidy from the old economy to the new that no start-up competitor could replicate. By FY26, Jio had 500 million subscribers, a net profit growing at 15 percent annually, fixed broadband market share of 43 percent, and was the world’s largest 5G operator outside China. India’s mobile data consumption, at approximately 33.6 gigabytes per user per month, is among the highest in the world and the cheapest per unit. The Jio investment, seen from 2026, was the most successful single bet made by any Indian company in the post-liberalisation era.
The Jio Ecosystem: Beyond Telecom
Jio was never solely a telecom company. From its inception, the strategy was to use the subscriber base as a distribution platform for a broader suite of digital services, including streaming video (JioSinema, now part of JioHotstar), music (JioSaavn), cloud storage, digital payments (JioMoney), news, education, and enterprise technology. Jio Platforms was created as the holding entity for all these digital businesses, and in 2020 became the recipient of one of the most remarkable fundraising rounds in Indian corporate history.
Between April and July 2020, Jio Platforms raised Rs 1,52,056 crore (approximately $20 billion at the time) from thirteen investors in less than three months. The investors included Facebook (now Meta) for Rs 43,574 crore, Google for Rs 33,737 crore, Silver Lake, Vista Equity Partners, KKR, General Atlantic, Mubadala, Abu Dhabi Investment Authority, Saudi Arabia’s Public Investment Fund, and others. The fundraising was done at a valuation of Rs 4.91 lakh crore for Jio Platforms, establishing it as one of the most valuable private technology companies globally. The 2020 fundraise also served a balance sheet purpose for RIL: the proceeds were used to make Reliance debt-free at the consolidated level by March 2021, ahead of the announced target.
Part VThe Four Business Segments in Depth
Reliance Industries operates across four principal business segments, each with distinct economics, growth rates, and strategic roles within the conglomerate. The interactive panels below summarise each segment’s mechanics, scale, and contribution to the FY26 results.
Oil to Chemicals (O2C)
1.4 mn bpdJamnagar crude processing capacity, world’s largest single-site refinery
21.1Complexity index at Jamnagar, highest in world, enabling processing of 216+ crude grades
>50%Share of RIL’s consolidated revenue from O2C in FY25, though EBITDA contribution is lower than consumer segments
The Oil to Chemicals segment encompasses Reliance’s entire hydrocarbons value chain from crude oil procurement through refining, petrochemicals, and fuel retail. The Jamnagar complex in Gujarat is the operational heart of O2C. It houses two refineries, a series of integrated petrochemical plants producing polyester, polypropylene, polyethylene, PVC, and paraxylene, and its own dedicated port facilities. Jio-bp, a 50:50 joint venture between Reliance and bp plc of the UK, operates India’s only significant private-sector petrol station network, with 2,125 outlets as of FY26 and volume growth of over 20 percent in both petrol and diesel in Q4 FY26.
FY25 saw O2C under margin pressure due to multi-year low spreads in downstream chemicals, particularly in polymers and polyesters where capacity additions from China created a sustained global supply surplus. FY26 saw partial recovery in transportation fuel cracks, and Q4 FY26 O2C EBITDA grew 20.9 percent year-on-year. The long-term strategic direction for O2C is decarbonisation through the New Energy segment: Reliance intends to use solar energy to power the O2C complex and green hydrogen as a feedstock to produce green chemicals and e-fuels, progressively shifting the segment from its fossil fuel base.
Jio Platforms (Digital Services)
500 mn+Jio subscriber base (end FY26), including world’s largest 5G base outside China at 234+ million subscribers as of Sep 2025
27.1 mnFixed broadband subscribers (end FY26), 43% market share, up 10 percentage points in 12 months
17.7%FY26 full-year EBITDA growth YoY; JPL EBITDA margin approximately 50% in FY25
Jio Platforms houses Reliance Jio Infocomm Limited (the mobile network operator) and all associated digital services businesses. Its mobile network carries more than 66 exabytes of data per quarter as of Q4 FY26, a 35 percent increase year-on-year, reflecting both subscriber growth and surging per-capita data consumption driven by 5G adoption. ARPU (Average Revenue Per User) reached Rs 206.2 in Q4 FY25 and continued growing into FY26 following the July 2024 tariff hike, which was the first broad-based retail tariff increase by any major Indian telecom operator since 2019.
JioFiber and JioAirFiber form the fixed broadband arm. JioAirFiber, which uses a home wireless router connected to the 5G network rather than a physical fibre cable, added 13 million subscribers by end-FY26 and drove over 75 percent of the fixed broadband additions in the year. Jio’s content ecosystem includes JioHotstar, formed through the combination of JioCinema and Disney+ Hotstar’s India operations, which had 500 million monthly active users in Q4 FY26 and set a global record peak concurrency of 72.5 million simultaneous viewers during the T20 Men’s Cricket World Cup Final. Akash Ambani, Mukesh’s elder son, is chairman of Reliance Jio Infocomm, marking the beginning of the third-generation leadership transition at Reliance.
Reliance Retail Ventures Limited (RRVL)
Rs 3.7L crFY26 annual revenue ($39+ billion), the largest retail business in India by a significant margin
20,160Total stores at end-FY26 across 78.3 million sq ft, spanning grocery, electronics, fashion, and wholesale
378 mnRegistered customers as of Q3 FY26 (December 2025), up 11.8% YoY; nearly 1.4 billion transactions in FY25
Reliance Retail is India’s largest retailer by revenue, store count, and customer base, and is among the ten largest retailers globally. Its portfolio spans five principal formats: Reliance Fresh and Smart (grocery and everyday essentials), Reliance Digital (consumer electronics and technology), Trends (fashion and lifestyle), JioMart (digital and hyperlocal commerce), and Ajio (online fashion, with the portfolio expanded 44 percent in FY25). Isha Ambani, Mukesh’s daughter, is Executive Director of RRVL and has been the public face of the retail business’s strategic direction since 2014.
The FY26 story for Retail was characterised by the rapid scaling of JioMart’s hyperlocal delivery business, which saw exit daily gross orders grow 2.4 times quarter-on-quarter in Q4 FY25. The business is positioned to compete with Zomato-owned Blinkit, Swiggy Instamart, and Zepto in the quick commerce segment. Consumer Brands, Reliance’s own-label FMCG business, became the fastest-growing FMCG business in India in its second full year of operation, achieving approximately Rs 11,450 crore in sales in FY25. In Q3 FY26, RRVL completed the demerger of its consumer products division, streamlining its structure. The company added 1,564 stores in FY26, reaching 20,160 outlets.
New Energy and New Materials
$10 bnInitial committed investment in clean energy, announced at the 2021 AGM; subsequent Gujarat MoU scale to Rs 5 lakh crore
40 GWhInitial BESS giga-factory capacity at Jamnagar, scaling to 100 GWh; LFP battery production commencing H2 2026
2035Reliance’s target year for net-zero carbon emissions across its operations
New Energy is the segment with the lowest current revenue contribution but the highest future strategic weight in Reliance’s portfolio. The Dhirubhai Ambani Green Energy Giga Complex (DAGEC) at Jamnagar is being built as an integrated clean energy ecosystem housing five giga factories: for solar photovoltaic manufacturing, lithium iron phosphate (LFP) battery cell production, hydrogen electrolysers, fuel cells, and power electronics. The scale of the complex, described by Anant Ambani at the 2025 AGM as four times the size of Tesla’s Gigafactory, represents the most ambitious single industrial construction project in India since the Jamnagar refinery itself.
On batteries: as of the FY26 annual report released May 28, 2026, the BESS giga-factory is in advanced commissioning stage, with LFP battery production expected to ramp up in the second half of 2026 at an initial capacity of 40 GWh, with a roadmap to 100 GWh. Equipment orders for the 100 GWh scale-up have already been placed. On solar: Reliance is constructing a 550,000-acre Kutch renewable energy project (a different project from DAGEC) that will supply captive power for green hydrogen production and commercial renewable supply to the grid. Power generation from Kutch is expected to commence in FY27. Anant Ambani, Mukesh’s younger son, heads the New Energy business, completing the three-way second-generation leadership allocation across the conglomerate’s three growth segments.
Part VIThe Financial Picture: FY25 and FY26 in Numbers
Revenue and Profit Growth: The Long-Run Picture
Reliance Industries’ financial trajectory from FY22 to FY26 reflects the structural shift in its business mix, from an O2C-dominated company where refining margins and chemical spreads determined annual results, toward a consumer-oriented conglomerate where Jio and Retail provide stable, domestically driven earnings growth insulated from global commodity cycles.

The Debt Position and Capital Efficiency
Reliance Industries’ debt management is as analytically significant as its revenue growth. The company made the unprecedented commitment in 2020 to become “net-debt-free” within eighteen months, a target it achieved by March 2021, funded in large part by the Jio Platforms fundraise of Rs 1,52,056 crore and the Reliance Retail fundraise of Rs 47,265 crore that followed in 2020-21. By FY25, net debt had returned to a moderate Rs 1,17,083 crore ($13.7 billion) at a net-debt-to-EBITDA ratio of just 0.64 times, reflecting the deliberate re-leveraging to fund capex rather than financial distress. In FY26, net debt rose to Rs 1,24,717 crore ($13.2 billion) as capex of Rs 1,44,271 crore was deployed.
What the 0.64x net-debt-to-EBITDA ratio means in context: Most large global integrated energy and diversified industrial companies operate at net-debt-to-EBITDA ratios between 1.5 and 3.5 times. Reliance’s 0.64 times in FY25 reflects an unusually conservative leverage position for its scale of capital investment. This conservatism is deliberate: Mukesh Ambani has spoken publicly about the importance of financial resilience after the Jio investment cycle stressed the balance sheet in 2017 and 2018. The low leverage ratio also gives Reliance significant capacity to increase borrowing to fund the New Energy buildout without approaching the thresholds at which credit rating agencies typically apply negative pressure.

The Succession Architecture: Three Businesses, Three Children
One of the most closely watched aspects of Reliance Industries’ corporate governance in recent years is the leadership transition being engineered by Mukesh Ambani. The architecture is visible and appears deliberate. Akash Ambani, the elder son, is Chairman of Reliance Jio Infocomm, the digital services business that is the group’s fastest-growing segment. Isha Ambani, the daughter, is Executive Director of Reliance Retail Ventures Limited, the consumer businesses segment. Anant Ambani, the younger son, heads Reliance New Energy, the capital-intensive future-bets segment. Each of the three next-generation Ambanis holds a distinct domain with its own P&L, its own management team, and its own strategic agenda.
This three-way distribution is structurally different from Dhirubhai Ambani’s failure to plan succession. Rather than leaving the entire empire without formal division, Mukesh Ambani has created parallel leadership tracks that can be formalised if and when a full transfer of responsibility is appropriate. Whether this architecture prevents a repeat of the 2002 to 2005 feud depends entirely on whether the next generation sustains the collaborative working relationships that the current architecture assumes.
Part VIIThe New Energy Bet and the Next Chapter
The Dhirubhai Ambani Green Energy Giga Complex
At the 2021 Annual General Meeting, Mukesh Ambani made the most consequential strategic announcement since the Jio launch: Reliance would invest $10 billion in a new energy business over three years. A subsequent MoU with the Gujarat government scaled the commitment further, to approximately Rs 5 lakh crore ($81 billion) over 15 years, encompassing 100 GW of renewable power projects, a green hydrogen network, and manufacturing facilities for solar modules, electrolysers, fuel cells, and batteries. The Dhirubhai Ambani Green Energy Giga Complex (DAGEC) in Jamnagar is the manufacturing hub at the centre of this plan.
DAGEC is designed as a vertically integrated clean energy production facility, mirroring the logic of the Jamnagar refinery at the previous technological frontier. Just as the O2C complex integrated crude processing and chemical production in a single location to maximise value and minimise logistics cost, DAGEC integrates solar cell and module manufacturing, battery cell production, electrolyser manufacturing, and power generation in a single location at Jamnagar. Reliance has acquired sodium-ion battery technology through its purchase of UK-based Faradion Limited for GBP 100 million, and LFP battery technology through the acquisition of assets from Lithium Werks for USD 61 million. Both technologies are being commercialised at the DAGEC site.
The net-zero 2035 target and what it requires: Reliance has committed to achieving net-zero carbon emissions across its operations by 2035, a target that is unusually ambitious for a company that derives the majority of its current revenue from oil refining and petrochemicals. Achieving it requires decarbonising the O2C business by replacing fossil fuel-based power and hydrogen with solar-powered green hydrogen produced at the Kutch renewable complex and the DAGEC facility. It requires electrifying the Jamnagar complex, transitioning process heat from natural gas to green hydrogen or electricity, and capturing or abating residual emissions. The $10 billion new energy investment is the financial foundation of this transition, but the 2035 target is acknowledged within the company as requiring sustained and accelerating investment beyond the current committed figure.
The Broader Strategic Significance: From Oil to Everything
The New Energy pivot represents more than a bet on clean technology economics. It is a strategic repositioning that reflects Mukesh Ambani’s assessment that the long-run economics of the O2C business, while structurally sound in the near term, face increasing headwinds from the global energy transition. The same reasoning that drove the Jio investment applies here: make the transition early, invest at scale before margins compress, build the enabling infrastructure that others will need, and capture the value of the transition rather than defending the margin of the incumbent business.
The three-segment consumer and digital businesses, Jio, Retail, and the nascent financial services platform of Jio Financial Services (now independently listed), provide the recurring cash flow base that funds the New Energy capex. The O2C business, despite its margin pressure in downstream chemicals, continues to generate substantial cash from its refining margins and transportation fuel operations. Together, they fund an investment programme that would be impossible for most energy companies to finance purely from balance sheet leverage. Reliance’s diversification, which has sometimes been criticised as complexity, is precisely the structural feature that enables this multi-generational transition.

What the Reliance Story Tells Us About India’s Economic Transformation
The Reliance Industries story from 1958 to 2026 is, at one level, a family business chronicle: a schoolteacher’s son from Chorwad who built an empire, left no will, created a succession crisis, and whose successors divided the empire before one rebuilt it and the other lost his. At another level, it is an almost perfectly calibrated mirror of India’s own economic journey: the License Raj exploitation of the 1960s and 1970s, the liberalisation windfall of the 1990s, the infrastructure boom of the 2000s, the consumer and digital expansion of the 2010s, and the energy transition of the 2020s. Every major phase of Reliance’s growth has been anchored to a shift in India’s economic structure.
Three strategic insights recur across the sixty-eight years of this story. First, vertical integration beats trading margins: every time Reliance moved one step backward in its supply chain, from trading to manufacturing, from manufacturing to refining, from refining to oil production, from telecom to digital services, from digital services to financial services, it captured a layer of value that pure traders could not access. Second, scale is a moat: whether at Jamnagar, where 1.4 million barrels per day and a complexity index of 21.1 creates an unmatched global position, or at Jio, where 500 million subscribers make the network more valuable to every incremental subscriber, Reliance has consistently bet on scale as a competitive weapon rather than niche differentiation. Third, cross-subsidisation enables disruption: the Jio launch was financed by O2C cash flows. The New Energy buildout is being financed by Jio and Retail cash flows. Reliance’s diversification is not an accident of conglomerate sprawl; it is the deliberate engine of each successive disruption.
The open questions for the next decade are significant. Whether the New Energy transition delivers commercial returns that justify Rs 5 lakh crore of investment depends on factors that are not yet resolved: green hydrogen production costs, global battery supply chain dynamics, India’s renewable power purchase agreement pricing, and the pace of the energy transition globally. Whether the succession architecture of Akash, Isha, and Anant Ambani avoids the conflicts of the previous generation is a governance question that no financial model can answer. And whether Reliance’s scale and dominance in telecom, retail, and refining attracts regulatory scrutiny of the kind that large platform companies have faced in Europe and the United States is a structural question for Indian competition policy. India’s largest company arrives at its sixty-eighth year with more capital, more subscribers, more influence, and more questions than at any previous point in its history.
Frequently Asked Questions
Reliance crossed the $10 billion net profit milestone in FY26 (the financial year ended March 31, 2026), reporting PAT of Rs 95,610 crore ($10.1 billion), an 18.3 percent increase over FY25’s Rs 81,309 crore. The achievement was driven by strong full-year growth in Jio Platforms (digital services EBITDA up 17.7 percent), Reliance Retail (revenue up 11.8 percent), and a partial recovery in O2C margins particularly in transportation fuel cracks. The FY26 EBITDA of Rs 2,07,911 crore grew 13.4 percent over FY25, with consumer businesses contributing more than 55 percent of total group EBITDA for the first time, marking a structural shift in the earnings composition. Mukesh Ambani confirmed the milestone at the results announcement, and the company announced a dividend of Rs 6 per share for FY26.
The Jamnagar refinery complex in Gujarat is the world’s largest oil refinery at a single location, processing 1.4 million barrels of crude oil per day across two adjacent refineries. Phase 1 was commissioned in July 1999 and Phase 2 (the export refinery inside a Special Economic Zone) was commissioned in December 2008. The complex covers more than 7,500 acres and houses not only the refinery units but integrated petrochemical plants producing polyester, polypropylene, polyethylene, and other downstream chemicals, its own dedicated port, and a captive power plant. Its Nelson Complexity Index of 21.1 is the highest of any refinery in the world, meaning it can process virtually any grade of crude oil, from light sweet grades to heavy sour varieties, and convert them into high-value products meeting the strictest global environmental specifications. This flexibility means Jamnagar can capture opportunities across the crude quality spectrum regardless of what is available in global markets at any given time. Strategically, it made India an export hub for refined products, positioned RIL as a significant participant in global fuel markets, and its export-oriented second refinery made Reliance the largest exporter of refined products from India.
Reliance announced the demerger of its financial services business on July 8, 2023, and Jio Financial Services Limited (JFSL) was subsequently listed as a separately traded company on Indian stock exchanges. The demerger separated RIL’s financial services portfolio, which includes insurance, asset management, payments, lending, and digital broking, into an independently governed entity with its own board and capital structure. A significant milestone for JFSL was the announcement of a 50:50 joint venture with BlackRock, the world’s largest asset manager, to enter the Indian mutual fund and wealth management market, with each party investing USD 150 million as initial equity. For Reliance’s overall structure, the demerger follows the same logic as the earlier Jio Platforms fundraise: by creating a separately listed entity, JFSL can attract investors specifically interested in financial services without them having to buy exposure to the entire Reliance conglomerate. It also allows JFSL to build its own balance sheet independent of RIL’s, a critical requirement for a financial services business that needs its own regulatory capital base.
Reliance’s FY25 EBITDA margin contracted by 70 basis points year-on-year to 17.1 percent, despite revenues growing 7.1 percent. The primary cause was the O2C segment, which faced two simultaneous headwinds. First, downstream chemical margins, specifically in polymers (polypropylene, polyethylene, PVC) and polyesters, were at multi-year lows due to massive capacity additions in China flooding global markets and reducing the spread between feedstock (naphtha, propylene) and finished chemical prices. Second, global refining margins, while positive, were more compressed than the elevated post-pandemic levels of FY23 and FY24. Consumer businesses (Jio and Retail) continued to grow at healthy margins, with Jio’s EBITDA margin approximately 50 percent and Retail’s margin improving, but these could not fully offset the O2C compression given O2C’s share of total revenue. In FY26, a partial recovery in transportation fuel cracks helped the O2C segment, and the full-year EBITDA margin recovered slightly to 17.7 percent, with consumer businesses at above 55 percent of EBITDA for the first time.
