Aeroflex Industries Ltd - The future of flexible engineering?

[somil.bhandari]

Overview

Aeroflex Industries is a Mumbai based manufacturer and supplier of metallic, flexible flow solutions including corrugated hoses, assemblies, and fittings; catering to both domestic and international markets. The company has shown consistent growth and is strategically shifting towards higher-margin assembly businesses and specialized applications.

Its products cater to diverse sectors such as oil & gas, steel, fire safety, solar energy, and emerging industries like electric vehicles and semiconductors. Aeroflex operates as part of the Sat Industries conglomerate.

The company is planning significant capex to expand capacity and diversify its product range into miniature metal bellows.

History

• Aeroflex Industries Limited was incorporated on October 19, 1993.1 Originally established as Suyog Intermediates Private Limited.
• The company underwent name changes to Aeroflex Industries Private Limited in 1998 and subsequently became a public limited company in 2006
• A significant milestone in its history was the acquisition by Sat Industries Limited in April 2018.
• Acquired Hyd Air in 2024 for 17 Cr, finances through internal accruals and IPO proceeds. This was done to facilitate entry into new sectors such as railways and shipbuilding.

Product portfolio

• Specializes in the manufacture and supply of environment-friendly metallic flexible flow solutions
• Stainless steel flexible hoses (both braided and unbraided)
• Assemblies, fittings, braiding, interlock hoses, composite hoses
• Future capital expenditure - miniature metal bellows

Assemblies and fittings accounts for highest revenue amongst others (~33% in FY 24). It is a high margin business and the company is focused to bring the assembly and components revenue share to around 80% over the next three years. With this change they are targeting EBITDA margin of ~27-28% over next three years.

Export focus
The company has a significant international presence, exporting its products to over 80 countries, with a substantial portion of its revenue derived from these exports. Exports accounted for 80.60%, 84.53%, and 80.90% in FY23, FY22, and FY21, respectively. his trend continued into FY24, with exports constituting 84% of the total revenue.

The company has witnessed an increasing demand for its products in international markets, particularly in developed economies. The company exports to over 80 countries, with a majority of its sales originating from the Americas and European regions.

They are strategically focusing on supplying solutions for specialized applications in industries such as semiconductors, aerospace, and pharmaceuticals. These specialized applications typically offer higher margins and face less intense competition.

Growth drivers
Aeroflex Industries operates within a sector benefiting from several tailwinds. There is an increasing demand for flexible flow solutions across various end-user industries, driven by infrastructure development, industrial growth, and the growing need for reliable and safe fluid transfer systems.
The global market for stainless steel flexible hoses is substantial and is projected to expand to US$ 38 billion by 2027. The Asia Pacific region is a leading exporter of stainless steel hoses, with significant growth coming from China and India. PLI schemes are also expected to support growth in the company’s end-user industries. Emerging sectors like electric vehicles, solar energy, and natural gas pipeline infrastructure are anticipated to further drive demand for flexible flow solutions.

Planned Capex
The company is planning ~100 Cr of capex in the coming years

• 54 Cr for increasing the capacity in stainless steel hose and braidings from 16.5 Million meters to 20 Million meters, along with increasing assembly stations from 40 to 70 and installation of automized welding stations
• 23 Cr for foray into miniature metal bellows
• 18Cr in Hyd air for new machines and equipments

Challenges

• The industry is competitive, necessitating continuous innovation and cost competitiveness.
• Fluctuations in the prices of raw materials, primarily stainless steel, pose a potential challenge to profitability.
• Given its substantial export and import activities, Aeroflex is exposed to volatility in foreign exchange rates.
• The current uncertain scenario due to fluctuating tariffs, wars and de-globlization can lead to demand and supply disruptions.
• Inherent risks associated with the introduction of a new product line, specifically miniature metal bellows, are subject to various risks, including market acceptance, production challenges, and competition from existing players in the niche market.

Valuation
The company’s TTM revenue stand at ~350CR with an EBITDA of ~77.6 CR at an EBITDA margin of 21.7%. Net profit stands at ~50CR.

The company has guided a revenue of ~650-675 Cr from assembly business after two years. From Hyd air, they are expecting a top line of 40-50 Cr in next couple of years (no specific timeline).
From miniature metal bellows, 25-30 Cr revenue is expected (again no specific timeline)
Along with this, they have guided an EBITDA margin of 24-25% by FY 27.

If we take a revenue estimate of ~725 Cr by FY 27 with an EBITDA margin of 24%, this gives EBITDA of ~174 Cr, and net profit of ~111 Cr.
The current PE is on a higher side for the industry, if we take a more conservative PE of 25 by FY 27, this gives an 18% upside from the current market price.
If the company continues to do good and enjoys a higher PE of ~30, it gives a potential ~42 % upside from the current market price.

Conclusion
While the current valuation seems to price in a good portion of future growth, potential remains—especially if margins improve as guided. That said, investors should be mindful of risks and maintain a margin of safety when considering Aeroflex Industries as an investment opportunity.

Disclaimer: Not holding right now, considering taking a starting position and will monitor future developments.

The parent company SAT industries is valued pretty attractively at PE of 12. Parent also has a track record of churning successful subsidiaries and has invested in lot of new entities. Worth a look

[Amit_8150]

Consider 120 additional revenue from metal bellows in 30/40/50 cr. from FY 26/27/28.

[Chandragupta]

Results look bad, with sales down 6 % and operating profits down 26 %. Management has largely blamed tariff related uncertainties, leading to customers deferring decision making and reducing inventories. Gross margins however remained intact, which is the only positive among the numbers. Capacity expansion plans remain on course, and QIP will be done only when an acquisition is finalized, said the management.

A few points from the concall:

1. Domestic growth was 30 %, exports de-grew.
2. Tariffs on products have increased from 3.5 % to 10 %. Customers have delayed orders, reduced inventories are they are not sure of the demand at their end, said the management
3. Guidance - 20 % growth EBIDTA, PAT will be lower due to higher depreciation.
4. Metal bellows & Hyd air - 15 % of sales coming from these two combined for the current year
5. Some of the products exported to Europe are ultimately exported to US only (customer’s finished product), so Europe exports are also affected
6. Aeroflex is the largest exporter of hoses & assemblies in India and we are the leaders in domestic market as well, says the management.
7. Metal bellows recorded revenues Rs.1.3 crores, 10 to 20 % of revenue this year expected to come from this. Metal bellows margins are 28 - 30 % at optimum capacity
8. We have different types of customers - some which give tentative quantities annual basis and then issue purchase orders from time to time based on their requirements.
9. Then there are projects - where we undertake design, prototyping, testing and ultimately production
10. And then there are regular product buyers who buy on a container basis

There were a lot of questions on the new data center cooling solution order announced by the company recently. Company said the order is to be executed in H2. It is a new demand and not a replacement of any existing customer. The product will be supplied to India market, for which the US based company has got a contract. Management has not named the company, but it is likely to be Flex Ltd. Management said Parker Hannifin & a UK based company Senior plc are its competitors in this field.

The announcement about ASME Certification for Bellows / Expansion Joints is also significant. It will expand the opportunity size for Aeroflex. Many critical industrial systems — especially in power, oil & gas, chemical, nuclear, marine, and now advanced data centers — reportedly mandate ASME-certified components for legal, quality, and insurance reasons. Many multinational clients, EPC (engineering-procurement-construction) firms, and large OEMs in the US, Europe, Middle East, etc., will only consider products with ASME stamping. Getting ASME certification is said to be a difficult, time-consuming, and resource - intensive process, which requires staff qualification, QA system, code shop inspection, design validation etc. The process often takes 6–12 months (sometimes longer) and can be costly to maintain. Only a handful of companies in India are certified for expansion joints / bellows like Bellman, EagleBurgmann India, and now Aeroflex joins the club.

Aeroflex Industries Ltd Q2 FY2025-26 Concall

Something interesting developing here…

[Preetish_Biswal]

Management likely has real-time order visibility and customer communication indicating demand revival. Their confidence in offsetting Q1 impact implies operational levers already being executed (pricing adjustments, domestic push, or cost rationalization).The project-based nature ensures backlog strength, creating a natural hedge against volatile export cycles.The firm is expanding horizontally (new OEMs) and vertically (wallet share with existing customers). This dual lever points to a likely stronger export rebound than guided, once macro constraints ease.

[vir259]

I agree. I think the only thing that is holding back the company at this point is tariffs. US customer orders are on hold. A lot of the products exported by the company would be categorized as precision engineering, hence not easy to replace with. Yesterday’s announcement that they are going ahead with expansion for supply to data center customer in the US proves this. In the meantime management is trying to compensate the shortfall by selling more domestically. Even a 25% penalty reversal will be very positive for the company.

[karanshah137]

The narrative of Aeroflex Industries is shifting from traditional industrial components to becoming a critical pillar of the AI revolution. They are aggressively expanding their capacity for liquid cooling skids, the essential “thermal shields” for modern data centers, aiming to jump from 2,000 to 13,000 units by June 2026.

Also, Ashish Kacholia is increasing his stake to 2.27% through a preferential issue at ₹182.70 per share.

[abhishekbagaria]

Yes, Totally agree. At 50% tariff, they loose their competitiveness against the local big players like Parker / Eaton etc. Their customers are still playing a waiting game, may have delayed some orders, but not changed the vendors yet. All expecting at least the 25% tariff to go soon. But if 50% tariff stays for another 2 quarters, the customers will be forced to change suppliers and that will be big negative for the company. That’s the biggest risk at the moment. Company’s about 35% of the revenue comes from US.
Currently as far as BTA is concerned there seems to be a bit of deadlock, between US and India.

[ravisingh7]

Aeroflex preferential shares issues for expanding on the liquid cooling solution. H2 FY 27 is probably when the revenue will start coming incrementally. https://www.bseindia.com/xml-data/corpfiling/AttachLive/ab8c6a07-fa63-46d7-94af-bb961ffc0ac5.pdf

[richbandit]

Who designs these Skids and what’re the optionalities that can play around with other clients? Aeroflex acts as a manufacturer or is it end to end product by Aeroflex only??

AEROFLEX- A Data Center Proxy

Here is a summary of Aeroflex Industries’ Secondary Fluid Network (SFN) solutions for data center liquid cooling:

Overview

The Secondary Fluid Network (SFN) is a critical infrastructure component for modern data centers, particularly those handling high-density workloads like AI and High-Performance Computing (HPC). It is a closed-loop system responsible for transporting coolants (such as water, glycol, or dielectric fluids) from Coolant Distribution Units (CDUs) directly to heat-generating IT equipment inside server racks.

Why It Is Essential

As rack power densities increase beyond the capabilities of traditional air cooling, liquid cooling has become necessary. The SFN serves as the “nervous system” of this setup, offering:

• 10x higher heat transfer efficiency compared to air.

• Lower Power Usage Effectiveness (PUE) and reduced carbon footprint.

• Support for ultra-high rack densities required by next-gen computing.

Aeroflex’s Core Solutions

Aeroflex provides an end-to-end mechanical flow infrastructure designed to handle the rigorous demands of the SFN, including zero tolerance for leaks and tight spatial constraints. Their solution includes four main components:

1. Stainless Steel Flow Systems: The structural backbone used for main distribution loops and CDU skid piping. They offer high structural integrity and corrosion resistance.

2. Metal Hoses (The Dynamic Link): Flexible connections that link rigid piping to dynamic equipment (like rack manifolds and cold plates). They are designed to absorb vibration and allow for compact routing without permeation.

3. Metal Bellows / Expansion Joints: Devices that compensate for thermal expansion and isolate mechanical vibrations, ensuring the network remains stress-free and reliable.

4. Precision Fittings: Leak-tight connectors engineered for high pressure and temperature, compatible with stainless steel systems to ensure safe operation near sensitive electronics.

Key Engineering Advantages

• Zero Leakage: Engineered to prevent fluid contamination near sensitive IT equipment.

• Durability: Resistant to fatigue from continuous vibration and thermal cycling.

• High Capability: Built to withstand high pressures and temperatures with material compatibility for various coolants.

• Sustainability: Directly contributes to energy efficiency and global sustainability objectives by enabling effective liquid cooling architectures.

Q3 and 9M FY 26 results and concall highlights -

Company’s products -

Corrugated Stainless Steel Hoses - suitable for temperature ranges from (-) 270 to 700 degree C, fire and moisture resistant, automatically compensate for thermal expansion and contraction, ideal for flexible pipings in difficult locations, have excellent corrosion resistant characteristics, resistant to abrasion and penetration damages

Company offers a wide grades and sizes of these hoses. They r used in various end industries like - refineries, steel plants, paper plants, fertiliser plants, pharma plants, lubrication systems, pneumatic and vacuum systems, railways, AC and refrigeration, boilers

Steel Hoses with braids -

When pressurised above a certain level, unbraided corrugated hoses tend to elongate. To prevent this, an external layer of stainless steel wire braiding is added to the hose, which prevents longitudinal expansion and increases the internal pressure strength of the hose by many folds. The stainless steel braided hose is usually wrapped around an existing tube and is highly flexible, which ensures that it does not impede the movements of the hose

Aeroflex is a notable stainless steel braided hose manufacturer in India. Depending on the requirement, they can offer single-layered or double-layered corrugated stainless steel braided hose. Braiding can also be supplied in copper, tinned copper, or stainless steel AISI 316, in case of bulk requirements

SS hose assemblies -

A hose assembly comprises of the hose and the end fittings, and are determined by the application in which the hose assembly is going to be placed. Compared to rubber and other materials which are used for hose pipes, stainless steel hose assemblies are an excellent choice for a variety of industrial usage and are suitable for the most demanding technical specification

Aeroflex stainless steel hose assemblies are engineered to perfection and are flexible & durable. They also allow for quick and easy installation and replacement

These braided stainless steel hose assemblies are resistant to high pressure and have a higher tear and tensile strength. They are also resistant to fire, abrasion, humidity, moisture, and penetration

These stainless steel braided hose assemblies also absorb vibration and noise from engines, pumps, compressors, etc as well as compensate for thermal expansion/contraction of piping

Gas Hoses -

EBITDA - 70 vs 62 cr, up 12 pc ( margins @ 22.2 vs 21.8 pc )

PAT - 37 vs 41 cr ( due sharp rise in depreciation )

Notes from Q3 concall -

Exports in Q3 grew 30 pc - despite the tariffs related headwinds

Added 1 million meters capacity in Q3 which took the total capacity up to 17.5 million meters / yr

Completed the supply of first set of liquid cooling equipment and assembly in Q3. Expanding capacities in this space by 7.5 X from 2k to 15k assemblies. Capex for this is expected to be slightly less than 100 cr. Realisation per assembly should be around Rs 3 lakh / assembly. At peak capacity utilisation ( of aprox 80 pc ) - this division should generate revenues of aprox 350 cr

Company is supplying liquid cooling equipment to US company’s Indian subsidiary

Company had acquired Hyd-Air Engineering company in 2024. Hyd-Air’s facilities are currently running @ 70 pc capacity utilisation. Plan to add more machines to expand their capacity. Exact details of capex shall be shared subsequently. Hyd-Air is a manufacturer of Hydraulic Fittings, Fluid Connectors & Flanges etc

Hyd-Air can do 40-50 cr of annual revenues at peak revenue potential

EU FTA and lowering of US tariff rates are a natural tailwind for the company

For 9Ms FY 26, most of the growth has come from Domestic and not export markets ( mainly because of weak Q1, Q2 + Q3 saw descent recovery )

In the Domestic mkts, most of the growth is being driven by Steel and Ports + Terminals Industries. In addition, Hyd-Air is witnessing strong growth pickup from railways

Company has added new customers in Ports + Terminals and Chemical industries ( in the domestic mkts )

Capex in 9Ms FY 26 has been @ 36 cr. Bulk of capex in liquid cooling equipment shall happen going forward. Breakup of capex is as follows -

Liquid cooling equipment - 9 cr

Metal Bellows - 5 cr

Hoses and Assemblies - 22 cr

Cash on books @ 20 cr ( as on 31 Dec 25 )

The liquid cooling business is expected to be margin accretive for the company. Consol company level margins should inch upwards towards 24-25 pc as the liquid cooling business scales up

Metal Bellows currently @ 12 cr / yr kind of run rate. Should ramp upto 36 cr / yr by H2 FY 27. Should further ramp upto > 80 cr / yr kind of run rate by early FY 29

Liquid cooling should achieve peak revenue run rate of 350 cr / yr by second half of FY 29

Aeroflex is presently the only player in India supplying liquid cooling systems for Data centers. Except Aeroflex’s supplies, these components are being imported

Post the capex mentioned above, peak revenue potential from each unit should be -

Hoses and assemblies - 650 cr

Metal Bellows - 80 cr

HydAir - 40 cr

Liquid cooling - 350 cr

Grand total - Aprox 1120 cr vs 376 cr achieved LY. This should be achieved by FY 29

All the expected liquid cooling equipment sales ( as mentioned above ) are for Indian mkts. Additional export opportunities may open up at a later stage

The 350 cr revenue potential ( iro liquid cooling assemblies ) is estimated as per the demand projected by their end customer ( Indian subsidiary of US firm )

Once the new tariff rates of 18 pc kick in, company’s margins may expand by 3 - 4 percentage points

Their US customer is really serious about their India Ops. In future, they also intend to develop Indian ecosystem for their international supplies. This can be really beneficial for Aeroflex being their exclusive supplier for liquid cooling

NETWEB TECH: VERTIV AND CO TO DELIVER RACK SOLUTIONS FOR AI DATA CENTERS IN INDIA

Is Aeroflex going to manufacture these?

[Mohit_Jariwala]

Right now aeroflex core focus is not on making a whole liquid cooling system.
Their core focus is to make cooling components and flow infrastructure example

1. Steel backbones: the main pipes
2. Flexible hoses: connectors to server racks
3. Bellows: parts that expand so pipes don’t break when hot.

They are working on specialized parts that make sure the liquid can travel safely and reliably.
And they are already tie up with vertive in which they are supplying parts to Vertive for the data center cooling system.

[Investor297]

Based on 5year exclusivity contract Aeroflex have for their (assumed to be Vertiv’s) India business, it will be manufacturer.

[karanshah137]

Aeroflex Industries’ entry into high-performance liquid cooling solutions for data centers.

Completed the first commercial dispatch of… flow control components and skid assemblies for liquid cooling applications.

Revenue target ₹1,000+ Cr by FY29
EBITDA margin target 23–25%
Value-added product mix already ~54%

Ashish Kacholia has Increased Stakes in the company.

[karanshah137]

HIGH-GROWTH STORY WITH LIMITED ROOM FOR ERROR NOW

The current valuation appears to factor in most future growth. The scarcity premium for data center cooling exposure is already priced in, and there is a limited margin of safety if execution deviates. Execution will be the single biggest driver of returns.

Neutral to positive in the near term.

How do they plan to fund the working capital? ST loans?- Then Interest cost should go up substantially. Any issue on WC side and struggle in core biz and you’re left holding onto something which is very expensive.
