4 Smallcap Companies that Reported Over 100% Growth in Profit

#2 Netweb Technologies

Coming second on the list is Netweb Technologies, a leading Indian-origin, owned, and controlled original equipment manufacturer (OEM). Netweb designs, manufactures, and deploys High-end Computing Solutions (HCS). Unlike standard hardware assemblers, Netweb actively distances itself from commoditised "box selling," focusing instead on providing fully integrated hardware and software solutions anchored in indigenous R&D and proprietary architecture.

Its comprehensive product suite spans high-performance computing (HPC) petascale supercomputers, private cloud and hyperconverged infrastructure, enterprise storage solutions, high-performance data centre servers, and network switches. This complete in-house control over system design and PCB layout acts as a substantial technological entry barrier, positioning the firm as a crucial infrastructure provider for research institutions, defence entities, and corporate enterprises.

The rise of artificial intelligence has transitioned from a boardroom buzzword into a tangible catalyst for corporate earnings, and nowhere is this more evident than in Netweb Technologies' earnings growth.

For the first quarter of FY27, Netweb delivered a standout PAT growth of 179.9% YoY. This bottom-line explosion was supported by a 172.1% surge in revenue. Far from a temporary spike, Netweb's blowout quarter reflects a deeper, structural shift in India's technology landscape, where sovereign demand and high-end indigenous manufacturing are converging to create a highly lucrative computing ecosystem.

The primary engine behind this quarter's massive top-line and bottom-line scaling was the AI Systems division, which grew by 484% YoY. This demonstrates that Netweb's growth is fundamentally volume-driven, fueled by an unprecedented domestic build-out of AI infrastructure.

Proactive planning and direct relationships with global OEMs like NVIDIA, AMD, and Intel have allowed Netweb to secure its pricing and bypass severe component inflation, meaning lower input costs did not drive this jump, but disciplined supply chain management certainly did.

From an earnings quality perspective, the numbers appear clean. There were no major one-off or non-recurring exceptional items reported that artificially bloated the quarterly profits. However, a key detail for investors to note is the execution of what the company previously termed "strategic orders". During the quarter, Netweb executed approximately Rs 4.3 bn of its massive Rs 16 bn strategic order. Management has officially normalised these large-scale engagements, stating that strategic orders are now a part of normal, recurring business and will no longer be segregated.

Coming to its long-term financial performance, the company has delivered a top-line growth of 70% CAGR over a 3-year period and a net profit CAGR of 64%.

The last 3-year ROE has been 29%.

Looking ahead, the structural tailwinds are undeniably strong; sovereign AI has transitioned from an aspiration to a national imperative, driven by India's sovereign foundation models and the IndiaAI Mission.

However, sustaining current pace will require navigating several operational bottlenecks. First, execution cycles have stretched from 8-12 weeks to 16-20 weeks due to the sheer complexity of deploying advanced liquid cooling and dense GPU architectures.

Second, the working capital requirements are intense. To hedge against global component scarcity, Netweb intentionally increased its inventory days, causing raw material stocking to rise.

This deliberate inventory buffer, combined with rapid order execution, has strained short-term liquidity, leading Netweb to close the quarter with a positive net debt of Rs 1,999 million for the first time in many quarters. Consequently, while the long-term demand runway is intact, the pace of cash-flow conversion may experience short-term friction.

Moving forward, serious investors should focus their attention on several key operational metrics. The first is working capital efficiency and the cash conversion cycle, which recently stood at 96 days, and how well the company manages its rising inventory buffers without excessively diluting capital efficiency. The second is supplier and customer concentration risk; historically, Netweb has relied heavily on its top three suppliers for 65% to 70% of procurement and its top five customers for a similar percentage of revenue. Any disruption in relations with key technology providers or failure to retain a skilled R&D workforce could immediately impact execution timelines.

On the guidance front, management is highly confident, targeting a sustainable 35% to 40% revenue CAGR over the coming years while maintaining steady operating margins.

#3 MTAR Technologies

On number three comes MTAR Technologies a precision engineering company that designs and fabricates complex, mission-critical systems and sub-systems for strategic sectors. It occupies a critical niche in India's national infrastructure, supplying Vikas liquid propulsion engines, cryogenic engine assemblies, and critical structural assemblies to ISRO, fuel handling systems to NPCIL, and solid oxide fuel cell hotboxes to global MNCs such as Bloom Energy.

Over time, the company has moved from build-to-print assemblies toward build-to-specification technologies, which has created a high technological barrier to entry and strengthened its position in strategic manufacturing.

In 1QFY27, MTAR reported a PAT growth of 364.5% YoY. Revenue rose 130.4% YoY, while EBITDA increased 199.7% YoY. EBITDA margin expanded by 5.5% to 23.6%.

The performance was structurally volume-driven. As production volumes rose across manufacturing facilities, fixed overheads were absorbed more efficiently, resulting in operating leverage. Margin expansion was also supported by productivity improvements, supply chain optimisation, and a richer product mix.

A key strength of MTAR's model is that it is relatively insulated from commodity volatility. The company works with price-escalation pass-through clauses and annual locked-in supplier pricing, which means the improvement in margins appears structural rather than dependent on short-term raw material movements.

Coming to its long-term financial performance, the company has delivered a top-line growth of 15% CAGR over a 3-year period and a net profit CAGR of -1%.

The last 3-year ROE has been 10%.

MTAR exited 1QFY27 with an order book of Rs 51.4 bn, which was further strengthened by an additional Rs 8 bn of order inflows secured immediately after the quarter-end. Together, this gives the company visibility on nearly Rs 60 bn of orders, comfortably above management's earlier target of closing FY27 with a Rs 50 bn order book.

The growth runway appears supported by multiple structural drivers. Civil nuclear power execution is expected to ramp up from the second half of FY27. Clean energy fuel cell capacities are expanding in phased tranches, with a major Phase 3 expansion targeted for completion by March 2027. At the same time, new export verticals such as data center infrastructure solutions and oil and gas equipment manufacturing are moving from qualification into volume production.

Looking ahead, Management has reiterated FY27 guidance of around 80% revenue growth and an EBITDA margin of 24% and has expressed confidence in outperforming these targets.

#4 Aeroflex Industries

Fourth on the list is Aeroflex Industries, a leading manufacturer of stainless steel corrugated flexible hoses, assemblies, fittings, metal bellows, and composite hoses used to transport liquids, gases, and semi-solids under extreme conditions. Its traditional business serves a wide industrial base, including ports, terminals, steel, petrochemicals, and energy.

More recently, the company has pivoted toward next-generation data centre cooling solutions through a strategic partnership with a leading US-based corporation. This has made Aeroflex an approved global supplier of Secondary Fluid Network, or SFN, liquid-cooling skid assemblies. These systems distribute coolant directly across high-density AI server racks and sit in a high-barrier, fast-growing market.

In 1QFY27, Aeroflex reported a 162.2% YoY rise in consolidated PAT. Consolidated revenue increased 72.4% YoY, supported by strong volume growth across both the core business and the emerging cooling vertical.

The core stainless-steel flexible hose and assembly business grew by over 40% YoY, but the key driver of the earnings surge was the rapid scale-up of the SFN liquid-cooling skid division. During the quarter, SFN skid assemblies generated Rs 324 m in revenue, contributing about 23% of total consolidated revenue. That compares with just Rs 212 m for the entire previous financial year, showing how quickly the new vertical has scaled.

The growth was structurally volume-led and supported by a richer product mix. The company's traditional hose business continued to see healthy demand, but the real margin expansion came from a shift toward value-added engineered assemblies and skids.

Raw flexible hoses typically earn EBITDA margins of 16% to 20%, while completed assemblies and skids command healthier margins of 22% to 26%. That mix upgrade helped materially lift profitability.

There is also a meaningful low-base effect, as the liquid-cooling skid business began commercial deliveries only in late FY26. However, the absolute dispatch numbers confirm that the growth is real. Aeroflex delivered 1,040 skids in 1QFY27, compared with 617 skids in the whole of FY26.

Coming to its long-term financial performance, the company has delivered a top-line growth of 18% CAGR over 3 years and a net profit CAGR of 20%.

The last 3-year ROE has been 16%.

The long-term opportunity is the broader shift from air cooling to liquid cooling in AI infrastructure, driven by rising rack densities in AI GPUs. India's planned data centre development pipeline is also very large, which provides a strong backdrop for demand.

Aeroflex's early-mover advantage and approved-vendor status with a leading global digital infrastructure provider create a meaningful competitive moat. However, quarterly numbers are likely to remain lumpy because skid dispatches depend on project schedules and on customer approvals before production can begin. Customer concentration under the central US contract is another factor that can lead to volatility in reported quarterly revenue, even if the multi-year trend remains strong.

Management has guided for a blended EBITDA margin of 25% over the next few years. To support that target, the company is scaling skid assembly capacity from 9,000 units to 15,000 units per annum by 3QFY27, backed by a Rs 480 m capex plan. It is also increasing flexible hose capacity from 17.5 million meters to 20 million meters per annum, with a Rs 540 m capex, and this segment alone has peak revenue potential of Rs 6.5 to 6.7 bn.

Conclusion

These four smallcap companies show that a sharp profit jump is meaningful only when it is supported by genuine business improvement, whether through operating leverage, capacity expansion, a better product mix, stronger execution, or improving demand fundamentals.

While the latest quarterly results highlight impressive earnings momentum, investors should focus on whether these gains are sustainable rather than driven by one-off factors or a favourable base. Monitoring execution, margin trends, working capital, customer concentration, and management's ability to deliver on growth plans will be crucial in assessing the durability of these businesses.

As always, investment decisions should be based on thorough research into a company's financials, business quality, competitive positioning, and corporate governance, while ensuring they align with your investment objectives and risk appetite.

Happy investing!
