AI Cooling Boom Fuels Triple-Digit Profit Surge

Two niche small-cap manufacturers are experiencing substantial profit growth, driven by vastly different opportunities. Aeroflex Industries is significantly expanding its revenue by supplying specialized liquid-cooling infrastructure for AI data centers, a business that emerged in its portfolio only two years ago. This AI-driven growth contrasts with Krishna Defence's success, which stems from its prominent role in India's burgeoning defense manufacturing sector, particularly supplying naval bulb bars and armored steel profiles.

Aeroflex's half-yearly performance showed an 81% revenue increase to ₹353 crore, with net profit surging 158.6% to ₹55.4 crore, though this was influenced by accounting changes. The company is scaling its liquid-cooling capacity, anticipating a global market growth of 33.2% CAGR through 2032. However, its Return on Capital Employed (ROCE) has declined to 20% in FY26 from 37% in FY23 due to a tripled asset base, necessitating a focus on improving asset turnover.

Krishna Defence, conversely, reported a 55.7% revenue rise to ₹75.3 crore and an 118.8% net profit surge to ₹15.1 crore, supported by strong operating performance and an asset-light model. Its ROCE improved to 27% in FY26. Key concerns for Krishna Defence include a significant rise in trade receivables and the need to convert its tender pipeline into firm orders to sustain its targeted 30% annual growth.

Valuation gaps are evident, with Aeroflex trading at a high P/E of 71.6 times, reflecting market expectations for its AI cooling business. Krishna Defence, at 38.2 times earnings, trades below industry averages, potentially awaiting greater order-book clarity. Investors must monitor Aeroflex's capacity utilization and Krishna Defence's order conversion and cash collection to assess their long-term performance.
