Contracts, capex, and chemistry: Is Aether Industries building an Asian Paints of specialty chemicals?

There's a new name doing the rounds in specialty chemicals: Aether Industries.
It's young, R&D-driven, and already counts global giants like Baker Hughes and Saudi Aramco as its clients. The company is growing fast, expanding capacity, and shifting focus toward high-value contract manufacturing, a space investors tend to favour.
But here's the catch: since its IPO in 2022, the stock has been flat. It had a brief 45% rally post-listing, but has since given up those gains. Over the last three years, it's essentially delivered no returns, even as the broader market moved up and peers like SRF or PI kept compounding.
So the big question is: does Aether finally have the pieces in place to break out? Or is it another story where the promise is strong, but the execution needs to catch up?
Let's dive in.
India's specialty chemicals industry has been one of the quiet compounding stories of the last decade. With China-plus-one tailwinds, a rising export share, and increasing focus on complex chemistries, Indian players like PI Industries, Navin Fluorine, and SRF have created enormous wealth. Aether wants to be part of that club, and it's playing a differentiated game to get there.
Aether Industries operates through three distinct verticals:
1. Large-Scale Manufacturing (LSM) – its high-margin products manufactured at scale.
2. Contract Manufacturing (CM) – long-term, exclusive agreements with global companies like Baker Hughes.
3. CRAMS – custom research and manufacturing services, where Aether helps clients take molecules from lab to plant.
This structure gives it both a foundation of predictable own-product revenue and optionality from custom or contract-led growth. Notably, the company is actively shifting its mix away from its own products toward higher-value exclusive manufacturing, which contributed 38% of revenues in Q4FY24.
Unlike peers who often scale on volumes or single chemistry platforms, Aether's moat lies in its deep chemistry capabilities and R&D intensity. The company works on complex chemistries like Grignard, organolithium, and cross-coupling reactions, processes that aren't easy to replicate at scale. That gives it an edge in attracting high-tech clients who need reliability and IP protection, not just capacity.
Aether also spends 7-9% of its revenues on R&D, among the highest in the industry, and runs a proprietary '8×8 matrix' to filter new molecules it wants to develop. This keeps its innovation pipeline sharp while reducing the risk of chasing low-margin products.
What makes Aether different is its focus on low-volume, high-complexity molecules. While some competitors chase scale through commoditised intermediaries, Aether prefers molecules that are difficult to make, harder to qualify, and stickier once approved. This is reflected in its customer list, which includes Saudi Aramco (Converge polyols), Baker Hughes (pour point depressants), and a range of Japanese and European firms in the pharma and materials space.
In FY24, over 50% of revenue came from exports, and the company isn't just shipping to emerging markets; it's supplying critical molecules to innovation-driven sectors like oilfield services and sustainable polymers.
Aether's revenue grew from Rs 1,092 crore in FY18 to Rs 6,511 crore in FY23, a six-year CAGR of over 35%. EBITDA margins hovered between 25% and 29%, aided by differentiated products and internal backward integration. However, FY24 was a pause:
Revenue fell 3% to Rs 6,374 crore,
EBITDA dropped to 25%, and
PAT slipped to 12% to Rs 963 crore.
The dip was largely due to a fire-related shutdown at its Site-2 plant and overall sluggishness in its LSM business. That said, the company bounced back sharply in FY25 YTD, with Q3 FY25 revenue growing 25% YoY, and margins improving to 29.8%, driven by better mix and operating leverage.
As of FY24, Aether had already invested over Rs 1,000 crore into capex. Sites 3+, 3++, and 5 (Panoli) are all under expansion, with Site-4 commissioned for the Baker Hughes contract. While this puts pressure on return ratios (RoE just 5% in FY24), the hope is that as contract manufacturing scales up, asset turns and ROIC will improve materially.
So far, the ingredients are niche products, credible global clients, capacity to scale, and a strong innovation culture.
What remains to be seen is whether this structure translates into sustained financial performance.
In late 2023, Aether Industries signed a strategic, exclusive supply agreement with Baker Hughes, one of the world's leading oilfield service providers. Under this deal, Aether will manufacture six specialty pour-point depressants — chemicals essential in transporting crude oil more efficiently.
These are high-spec, high-margin products, and not something many Indian players have traditionally supplied at scale. To support this contract, Aether has already commissioned Site-4, with commercial production expected to begin by the end of FY25.
At full ramp-up, the deal is expected to contribute over Rs 3,000 crore annually, significant for a company that reported over Rs 6,000 crore in revenue last year.
More than just numbers, this partnership signals Aether's arrival as a serious player in global contract manufacturing.
While the Baker Hughes contract provides near-term growth, Aether is also placing a longer-term bet on sustainable materials. Through a licensing partnership with Saudi Aramco's Converge business, Aether has secured exclusive rights to manufacture CO₂-based polyols in India.
These materials, used in coatings, adhesives, and elastomers, are partially derived from captured carbon dioxide, making them part of a growing push toward carbon-neutral chemistry. The company has built a 2,000 TPA production line for these polyols and is in early-stage discussions with global buyers. This segment may not drive immediate revenue, but it positions Aether well in a future where green chemistry could become the norm, not the niche.
Aether's growth isn't limited to marquee contracts. The company is also steadily expanding its global footprint. Over 50% of FY24 revenues came from exports, spanning Japan, Europe, the US, and the Middle East. These exports aren't commoditised APIs or bulk intermediates, but niche, high-spec molecules used in pharmaceuticals, materials science, and oilfield services.
In just the first nine months of FY25, Aether added 31 new customers, many of them global names. This export momentum adds a layer of resilience to the business, reducing dependence on any single sector or geography.
To meet rising demand, Aether is deep into a capex cycle. The company has recommissioned Site-2, which was temporarily shut due to a fire, and is on track to launch extensions at Site-3 (3+ and 3++) by the end of FY25. A new greenfield plant — Site-5 at Panoli — is also expected to be operational by December 2025.
These expansions are not just about volume, but about building modular, high-spec facilities that can cater to complex chemistry needs. Over time, they will form the backbone of Aether's CRAMS and contract manufacturing push.
Since its IPO in 2022, it rallied around 40% at one point, only to give up most of those gains. Over the last three years, the stock has largely moved sideways, even as the company kept expanding its capacity and client base.
Today, the stock trades at nearly 65 times forward earnings, a valuation that reflects high expectations. That multiple places it well above several established players in the specialty chemicals space.
The market, in effect, is betting that Aether's next phase, driven by the Baker Hughes contract, export growth, and premium products like Converge polyols, will translate into steep revenue and profit growth over the next few years.
If Aether executes to plan, with revenue compounding at 25-30% and margins holding or improving, the current valuation may be justified in hindsight, especially if return ratios improve as operating leverage kicks in and high-margin contracts ramp up. In that case, investors could see earnings catch up with the stock price, and possibly more.
But that's a scenario built on smooth execution. Any delays in capacity utilisation, hiccups in contract scale-up, or margin pressures could result in the valuation looking stretched. What's clear is that this is a stock priced for growth, not for safety.
Aether's biggest strength is its ambition, which can also be its key risk.
The company is executing multiple large-scale projects simultaneously, and while that sets it up for growth, it also creates room for delays, cost overruns, or slower-than-expected ramp-ups. Contracts like the one with Baker Hughes, while exclusive, are volume-based and don't guarantee offtake, which means execution and demand will both have to line up.
Then there's the issue of operating leverage. Aether's margins have historically been healthy, but with capacity expansions and a shifting product mix, they'll have to fight to maintain those levels, especially as competition increases and client expectations tighten.
Investors should also keep an eye on working capital cycles. Specialty chemicals is a cash-intensive business, and with an expanding client base, receivables can stretch. Any mismatch in execution could lead to pressure on cash flows, especially when capex commitments remain high.
In short, this is not a business priced for stability, it's priced for growth. And while the building blocks are impressive — deep R&D, global clients, and a differentiated product mix — investors will need to watch execution closely over the next 12-18 months.
Aether Industries has all the ingredients of a potential long-term winner: a differentiated business model, global contracts, high R&D intensity, and a leadership team that's thinking 5-10 years ahead. In many ways, it represents what the new wave of Indian manufacturing can look like: niche, knowledge-driven, and globally relevant.
But at the same time, the stock market isn't waiting for all the proof. At 65x forward earnings, it's already giving Aether the benefit of the doubt. That makes it less of a value pick and more of a high-conviction, high-expectation story.
If the execution plays out, especially on the Baker Hughes ramp-up, Converge polyol scale-up, and consistent export growth, the upside could be meaningful. But if things fall short or take longer than expected, the valuation leaves little room for disappointment.
For investors, this may not be a stock to back blindly, but it's definitely one to watch closely. And for those with a long-term horizon and the patience to ride out short-term volatility, Aether could still turn into a quiet compounder, just not on autopilot.

Apple's China supply chain remains strong despite focus on India, SE Asia

China still enjoys dominance in Apple's key supply chain segments, even as the global tech giant's share of electronics manufacturing in the country has dropped from around 70 per cent to 50 per cent over the last seven years amid increasing focus on India and Southeast Asia, a report by a US-based public policy think-tank American Enterprise Institute (AEI) said. According to the report, key supply chain segments, such as printed circuit boards, printing and packaging, molded and mechanical components, and especially precision manufacturing remain predominantly in China, leaving scope for policymakers in countries like India to focus on attracting investment from its suppliers in such manufacturing capabilities. Interestingly, despite this dominance, Chinese-owned firms generally only play a role in lower-value segments of the supply chain. Many of the higher-value components— even those made in China— are produced in factories owned by Japanese, Taiwanese, or US firms, the report said. It indicated that the monopoly of China in electronics manufacturing for Apple is declining over the years. The assembly of all components into a device— the final step in the production process— is referred to as electronics manufacturing or assembly. 'Beginning in 2018, Apple began to shift its electronics manufacturing footprint, presumably driven by the 2018 US tariffs on China. Before 2018, around 60–70 per cent of electronics manufacturing locations were in China, including nearly all final assembly of key devices like iPhones. Today, by contrast, around 50 per cent of Apple facilities are in China, with increased factory share in India and Southeast Asia,' the report said. Of the 17 companies conducting electronics manufacturing in Apple's supply chain, only two are Chinese. Of the 34 electronics manufacturing facilities reported in China, only three are operated by Chinese firms. The report suggests that policymakers in India and countries in Southeast Asia seeking to attract investment and upgrade their manufacturing capabilities have substantial scope to continue attracting suppliers of companies like Apple, in not only basic assembly, but also some of the other component categories. 'The fact that many of these China-based factories are owned by foreign firms facilitates potential supply chain shifts. Moreover, as western electronics firms face higher tariffs, they are looking for more diversified production locations,' it said. The report is authored by Chris Miller, a non-resident senior fellow at the AEI, and Vishnu Venugopalan, a fellow at Harvard University and an Indian Administrative Service officer. It added that the assembly process for devices like phones often only cost around $10, a tiny fraction of its price. Hence, if tariffs lead to a shift in electronics manufacturing, shifting final assembly from China to a different country — without any other changes in its supply chain – will have minimal impact. Interestingly, the US major has diversified the battery ecosystem, which was solely dependent on China and South Korea till 2018, to multiple other countries. 'Today, however, it procures battery components from five different regions, including India and Southeast Asia. While over half of Apple's battery component sourcing locations remain in China, more than 40 per cent of locations are now outside China, representing a significant shift in Apple's production footprint. Notably, the concentration of China-based manufacturing facilities is greater than the share of Chinese firms. As of 2023, there were firms headquartered in Taiwan, South Korea, and Germany in Apple's battery supply chain—more non-Chinese firms (five) than Chinese (four)," it stated. The connectors and cables category involve some low-end products and some that require more high-end, specialty chemicals. 'The enduring position of Japan-based manufacturing in this category illustrates the higher-end manufacturing involved in certain components. Other segments, however, have seen a substantial shift from China to India and the 'other' category, mostly Southeast Asian countries,' it added. Of the nine companies producing products in this category, only one is Chinese. Other firms in this category with China-based manufacturing are American, Taiwanese, or Japanese — companies like Amphenol (US), Japan Aviation Electronics Industry (Japan), Furukawa Electric (Japan), and Hirose Electric (Japan).

Acerpure 135 AW cordless dry vacuum cleaner promises a lot under ₹15000: Smart buy or just a budget bet?

Acerpure, a relatively new name in the home appliance space, introduced a range of its cordless stick vacuum cleaners in the Indian market earlier in March. One of the vacuum cleaners, the Acerpure-Cordless Stick Dry Vacuum Cleaner 450W is priced under ₹ 15,000 on Amazon. It promises powerful suction, a smart digital display, multiple attachments and flexible cleaning modes, all features typically found in higher-end models. Hard to believe, right? So, I decided to try it. I put it to the test across different surfaces, spaces and messes. From unboxing and setup to real-world use, here's a closer look at what this new launch has to offer. Unboxing the Acerpure cordless vacuum cleaner I thought unboxing a vacuum would take five minutes, but turns out, I was signing up for a full-on weekend DIY project. You'll need to assemble everything, from the battery and extension tube to the brush heads, before getting started. The manual thankfully does a decent job of breaking down the steps. It's not complex, but it's definitely a process. There are plenty of attachments too. Let's break down what we get in the box. Acerpure includes an impressive range of accessories in the box, covering most household cleaning needs: A smart floor head Tube and hose attachments Separate brushes for carpets, beds, and pets A crevice tool, dusting brush, foldable tube connector and wall mount Adapter and additional modular parts This means you can switch between vacuuming floors, sofas, mattresses or even car interiors without much hassle. The foldable connector especially helps in reaching under furniture without bending too much. First impressions: Design and ease of use The Acerpure vacuum looks sleek and premium at first glance, but it's not exactly lightweight. Once fully assembled with the extension tube and brush heads, the main unit feels top-heavy, especially around the motor and dust cup. If you're cleaning for long stretches, you will have to pause and rest your arms. That said, the controls seemed intuitive with a digital display that shows battery percentage and the 3 cleaning modes, Auto, Mini and Max. You can toggle between them using a separate button. I mostly used Auto mode as it adjusts suction based on the surface and works fairly well. One downside is that the vacuum doesn't stand on its own. You either lean it awkwardly or park it in the wall mount. Not to mention, the wall mount is actually quite useful if you're short on space, but this feature keeps breaking the cleaning flow. The Acerpure cordless vacuum offers strong suction that handles most regular cleaning needs with ease, with a 450W motor. It's designed more for dry dust and debris than heavy-duty messes. I tested it on tiles, low-pile carpets, doormats, rugs and upholstered furniture. On tile floors, the vacuum glides smoothly and picks up dirt in a single pass. Cleaning the sofa corners and fabric surfaces was easy too. However, it does struggle slightly with lightweight rugs, they tend to lift or get caught in the brush, especially in Max mode, so you need to be cautious. The Smart Floor Head comes with two rollers, one for hard floors and one for carpets. The vacuum does get loud, especially at higher power levels. While it's not unbearably noisy, it's not the quietest either. What stood out to me was the dust container capacity. It's large enough to complete a full round of cleaning, floors and furniture, without needing to be emptied frequently, which saves time and effort. Battery life and charging The vacuum claims to run for up to 60 minutes in low mode and about 10 minutes on high power. From my experience, the battery held up for around 45–50 minutes in mixed usage (mostly Auto mode). That's sufficient for a 2BHK flat in one go. Charging time is around 3.5 to 4 hours, which is on the longer side but expected for this price range. You can charge it in three ways: directly, via wall mount (which also holds the spare battery), or by plugging the battery separately. No fast charging support, though, so you will need to plan ahead if you're cleaning a larger space. Emptying the dust cup is easy and mess-free, just press and release the button and the dust cup lip opens up. You can also remove the whole dust cup attachment to clean or wash it separately. The manual includes detailed diagrams on removing the filter and cleaning the brush heads. Do note that while the HEPA filter is washable, you'll need to air-dry it thoroughly before reusing. A neat feature is the blockage indicator, which lights up when there's a clog or when filters need attention. One standout design choice is the foldable tube connector, which allows the vacuum to bend at a 90° angle. This helps clean under low furniture without kneeling. The wall-mount is handy too, it keeps the device and accessories organised and off the floor. However, it takes a bit of getting used to if you're switching from a floor-standing unit. Slightly top-heavy design makes it less comfortable for longer cleaning sessions. Charging takes time, and there's no battery level warning until it's nearly drained. Doesn't stand tall without a support. A little learning curve for changing the attachments. Only one HEPA filter is included, no backup in the box. Is the Acerpure 135 AW cordless vacuum cleaner worth the price? At a 54% discount, the Acerpure Cordless Stick Vacuum currently retails at ₹ 13,690, making it a competitive option in the under ₹ 15,000 range. You get solid suction power (135 AW), a full set of cleaning attachments, a digital display with helpful alerts and flexible cleaning modes. It's also backed by a 1-year warranty.

Bad news for Pakistan, China as India not waiting for Russian SU-57 or US F-35 fighter jets, IAF making its own fighter planes more dangerous...

An image of British F-35B fighter jet used for Representational purpose Advanced Medium Combat Aircraft (AMCA) programme: In a significant achievement for India's defence sector, media reports have it that the Indian government is currently not in any formal talks to purchase advanced fighter aircraft like the Russian Su-57E or the American F-35. Instead, it is relying on indigenous Advanced Medium Combat Aircraft (AMCA). Here are all the details you need to know about India's very own Advanced Medium Combat Aircraft (AMCA), which is being called India's answer to fifth-generation air power. India's Advanced Medium Combat Aircraft (AMCA) programme In a big step towards 'Atmanirbhar Bharat' in Defence sector, Defence Minister Rajnath Singh recently approved the Execution Model for the Advanced Medium Combat Aircraft (AMCA) programme. Readers should note that the AMCA clearance marks a critical step towards realising India's goal of joining an elite club of nations in designing and producing its own fleet of next-generation combat aircraft. The project will be helmed by the Aeronautical Development Agency (ADA) of the Defence Research and Development Organisation (DRDO), said the Defence Ministry in a press release. 'Both private and public sector entities would do bidding for the project, either independently or as a joint venture or as consortia. The entity/bidder should be an Indian company compliant with the laws and regulations of the country,' said the MoD statement. India's answer to fifth-generation air power The AMCA, widely seen as India's answer to fifth-generation air power, will give a major boost to achieving 'atmanirbharata' in the defence sector and will become a hallmark of India's growing defence capabilities. Being the fifth-generation stealth multirole fighter equipped with cutting-edge technology, it will be suited for all-weather operation. Designed with low radar cross-section and supercruise capability, the AMCA is seen as the successor to the frontline Sukhoi Su-30MKI fighter jets. Some reports suggest that its mass production is likely to commence by 2035. (With inputs from agencies)
