With a market capitalisation of ₹8,777 crores, Apollo Micro Systems has emerged as a key beneficiary of India's defence modernisation drive, though its premium valuation of 109 times trailing twelve-month earnings and elevated debt levels warrant careful scrutiny. The quarter's performance was driven by exceptional 68.63% sequential revenue growth and margin expansion, though the company continues to grapple with rising interest costs and working capital pressures.
| Quarter | Sep'25 | Jun'25 | Mar'25 | Dec'24 | Sep'24 | Jun'24 |

Financial Performance: Exceptional Revenue Acceleration Drives Profitability
Apollo Micro Systems' Q2 FY26 performance showcased remarkable operational momentum, with net sales surging 68.63% sequentially to ₹225.26 crores from ₹133.58 crores in Q1 FY26. On a year-on-year basis, revenue growth remained robust at 40.17%, significantly outpacing the broader aerospace and defence sector's muted performance. The company's ability to execute large defence contracts and convert its substantial order book into revenue has been a key differentiator.
Operating profit excluding other income stood at ₹59.19 crores in Q2 FY26, translating to an operating margin of 26.28%. Whilst this represents a sequential contraction of 436 basis points from Q1 FY26's exceptional 30.64% margin, it marks a substantial 578 basis points improvement over the 20.47% margin recorded in Q2 FY25. The margin compression from the previous quarter reflects the lumpy nature of defence contracts and varying product mix, though the company maintained healthy double-digit profitability.
Net profit margin expanded to 13.33% in Q2 FY26 from 9.79% in the year-ago quarter, demonstrating improved operational leverage despite rising interest costs. The company's profit before tax grew 92.17% year-on-year to ₹43.15 crores, with tax expenses of ₹13.12 crores at an effective rate of 30.41%, broadly in line with statutory requirements.
On a half-yearly basis (H1 FY26), the company reported consolidated net sales of ₹358.84 crores, representing 63.84% of the full-year FY25 revenue of ₹562 crores. This suggests the company is well-positioned to exceed previous year's performance, though the lumpy nature of defence orders means quarterly volatility is likely to persist.
Operational Challenges: Rising Debt Burden Clouds Strong Growth Story
Whilst Apollo Micro Systems' topline growth trajectory remains impressive, the company's balance sheet reveals mounting pressure from elevated debt levels and working capital requirements. Long-term debt surged to ₹69.76 crores as of March 2025 from just ₹9.44 crores a year earlier, representing a staggering 639% increase. This aggressive debt accumulation has been driven by capacity expansion initiatives and the need to fund extended working capital cycles inherent in defence contracting.
Interest expenses climbed 73.08% year-on-year to ₹12.60 crores in Q2 FY26, consuming 29.19% of operating profit compared to 22.13% in the year-ago quarter. The company's interest coverage ratio, measured by operating profit to interest, stood at 4.70 times in Q2 FY26, an improvement from 4.52 times in the previous year but below the comfort threshold of 6-7 times typically desired for manufacturing companies.
Return on equity (ROE) remained weak at 5.82% on average, significantly trailing industry benchmarks and peer performance. This subdued capital efficiency reflects the capital-intensive nature of the business and extended gestation periods for defence projects. Return on capital employed (ROCE) of 10.12% similarly indicates modest returns relative to the capital deployed, raising questions about the sustainability of the company's aggressive expansion strategy at current profitability levels.
⚠️ Working Capital Pressure: A Critical Monitoring Point
Apollo Micro Systems' cash flow from operations turned negative at ₹75 crores in FY25, driven by a ₹112 crore increase in working capital requirements. Current assets ballooned to ₹1,029.28 crores whilst current liabilities reached ₹577.08 crores, indicating stretched receivables and inventory cycles. The company's debt-to-equity ratio of 0.27 remains manageable, but the rapid debt accumulation trajectory warrants close monitoring. Trade payables increased to ₹279.94 crores, suggesting the company is leveraging supplier credit to manage cash flows.
Employee costs rose 23.83% year-on-year to ₹6.34 crores in Q2 FY26, broadly in line with revenue growth but indicating ongoing talent acquisition to support expansion. Depreciation expenses increased to ₹4.75 crores from ₹3.75 crores, reflecting the capitalisation of new manufacturing facilities and equipment.
Valuation Analysis: Stratospheric Multiples Reflect Growth Optimism but Limit Margin of Safety
Apollo Micro Systems trades at a trailing twelve-month price-to-earnings ratio of 109 times, representing a significant premium to the aerospace and defence industry average of 49 times. This valuation places the company amongst the most expensive stocks in its sector, with only MTAR Technologies commanding a higher multiple at 158 times earnings. The stock's price-to-book value of 8.28 times similarly reflects elevated expectations, particularly when juxtaposed against the company's modest 5.82% return on equity.
The company's PEG ratio of 2.21 suggests the stock is trading at more than twice its earnings growth rate, traditionally considered expensive territory. Enterprise value-to-EBITDA of 53.04 times and EV-to-sales of 13.80 times further underscore the premium valuation, leaving limited room for disappointment. Investors are essentially paying ₹13.80 for every rupee of sales, a ratio that demands sustained execution excellence and margin expansion to justify.
The stock's 52-week range of ₹101.05 to ₹354.65 highlights significant volatility, with the current price of ₹250.15 positioned 147.55% above the low but 29.47% below the peak. This suggests some valuation correction has occurred from euphoric levels, though the stock remains richly valued by most metrics. The company's minimal dividend yield of 0.09% offers little income cushion, with a payout ratio of just 3.55% indicating management's preference to retain earnings for growth investments.
Peer Comparison: Valuation Premium Justified by Growth but ROE Lags Competition
Apollo Micro Systems' positioning within the aerospace and defence sector reveals a mixed competitive picture. The company commands the highest P/E multiple at 109 times amongst listed peers, substantially above Data Pattern's 63 times, Zen Technologies' 46 times, and Astra Microwave's 54 times. This premium reflects investor confidence in the company's growth trajectory and order book visibility, though it also exposes shareholders to heightened valuation risk.
| Company | P/E (TTM) | P/BV | ROE (%) | Debt/Equity | Div Yield (%) |
|---|---|---|---|---|---|
| Apollo Micro Systems | 109.16 | 8.28 | 5.82 | 0.27 | 0.09 |
| Data Pattern | 62.97 | 10.41 | 13.02 | -0.30 | 0.28 |
| Zen Technologies | 46.13 | 6.73 | 11.43 | -0.45 | 0.15 |
| MTAR Technologies | 157.76 | 14.06 | 10.28 | 0.23 | 0.00 |
| Swan Defence | NA (Loss Making) | 40.00 | 0.00 | 10.54 | 0.00 |
| Astra Microwave | 53.98 | 7.48 | 10.48 | 0.08 | 0.24 |
However, Apollo Micro Systems' return on equity of 5.82% significantly underperforms peers, with Data Pattern delivering 13.02%, Zen Technologies at 11.43%, and Astra Microwave posting 10.48%. This ROE gap suggests the company is less efficient at converting shareholder capital into profits, a concern that becomes more pronounced given its premium valuation. The company's debt-to-equity ratio of 0.27 sits in the middle of the pack, more conservative than Swan Defence's highly leveraged 10.54 but higher than the net cash positions of Data Pattern and Zen Technologies.
Apollo Micro Systems' price-to-book value of 8.28 times appears relatively attractive compared to Data Pattern's 10.41 times and MTAR's 14.06 times, though this metric must be viewed in context of the underlying ROE differential. The company's minimal dividend yield of 0.09% trails most peers, with only MTAR and Swan Defence offering no dividend at all.
Shareholding Dynamics: Promoter Stake Volatility Raises Governance Questions
Apollo Micro Systems' shareholding pattern has witnessed notable fluctuations over recent quarters, with promoter holding declining to 51.98% in December 2025 from 55.12% in March 2025. This 3.14 percentage point reduction over three quarters, including a sharp 4.47 percentage point drop between March and June 2025, has raised eyebrows amongst governance-focused investors. Whilst promoters retain majority control, the downward trajectory warrants monitoring for potential dilution or stake sales.
| Category | Dec'25 | Sep'25 | Jun'25 | Mar'25 | QoQ Change |
|---|---|---|---|---|---|
| Promoters | 51.98% | 50.33% | 50.65% | 55.12% | -0.43% |
| FII | 4.97% | 8.94% | 7.16% | 0.93% | -2.87% |
| Mutual Funds | 1.18% | 1.34% | 1.55% | 0.22% | -0.09% |
| Other DII | 0.12% | 0.11% | 0.06% | 0.15% | +0.01% |
| Non-Institutional | 41.76% | 39.27% | 40.59% | 43.59% | +3.38% |
Foreign institutional investor (FII) holding has exhibited significant volatility, surging from 0.93% in March 2025 to 8.94% in September 2025 before retreating to 4.97% in December 2025. This 2.87 percentage point sequential decline in the latest quarter suggests profit-booking by overseas investors following the stock's strong rally. The overall FII holding of 4.97% remains modest by large-cap standards, indicating limited institutional endorsement at current valuations.
Mutual fund participation remains anaemic at just 1.18%, having peaked at 1.55% in June 2025. The consistent reduction in MF holdings over subsequent quarters reflects cautious positioning by domestic institutional investors, possibly concerned about valuation levels and execution risks. With only three mutual fund schemes holding the stock and total institutional ownership (FII + MF + Insurance + DII) at a mere 6.26%, Apollo Micro Systems lacks the institutional support base typically associated with sustained upward momentum.
Non-institutional holdings increased to 41.76% in December 2025 from 38.38% in the previous quarter, suggesting retail investor accumulation. However, this category's dominance also implies higher volatility risk, as retail shareholders tend to exhibit lower conviction during market corrections. The reported 34.18% pledging of promoter shares, whilst not unusual for small-cap companies, adds another layer of concern regarding financial flexibility and potential margin calls during market stress.
Stock Performance: Exceptional Multi-Year Returns Mask Recent Consolidation
Apollo Micro Systems has delivered extraordinary wealth creation over longer time horizons, with the stock generating a staggering 1,992.43% return over five years compared to the Sensex's 63.78% gain. This translates to an alpha of 1,928.65 percentage points, placing the company amongst India's top-performing small-cap stocks. The four-year return of 1,698.35% and three-year gain of 647.05% similarly underscore the stock's remarkable trajectory, driven by India's defence indigenisation push and the company's successful order execution.
| Period | Stock Return | Sensex Return | Alpha |
|---|---|---|---|
| 1 Day | +3.88% | +0.58% | +3.30% |
| 1 Week | +1.40% | +2.94% | -1.54% |
| 1 Month | +1.54% | +0.59% | +0.95% |
| 3 Months | -6.99% | +1.02% | -8.01% |
| 6 Months | +41.21% | +5.27% | +35.94% |
| YTD | -8.10% | -1.36% | -6.74% |
| 1 Year | +95.05% | +7.97% | +87.08% |
| 2 Years | +106.74% | +17.42% | +89.32% |
| 3 Years | +647.05% | +38.25% | +608.80% |
| 5 Years | +1,992.43% | +63.78% | +1,928.65% |
However, near-term performance reveals a different narrative. The stock has declined 6.99% over the past three months and is down 8.10% year-to-date, underperforming the Sensex by 6.74 percentage points in 2026. This consolidation follows the stock's meteoric rise and suggests investors are reassessing valuations in light of the broader market correction and sector-specific headwinds. The one-year return of 95.05% significantly outpaced the aerospace and defence sector's 1.41% decline, generating a remarkable 96.46 percentage points of outperformance.
The stock's high beta of 1.35 indicates significantly greater volatility than the broader market, with risk-adjusted returns of 1.64 over one year compared to the Sensex's 0.69. Whilst this volatility has rewarded patient investors during the uptrend, it also implies heightened downside risk during market corrections. The stock's 58.03% volatility over the past year, nearly five times the Sensex's 11.53%, classifies Apollo Micro Systems as a high-risk, high-return proposition suitable primarily for aggressive investors with strong conviction and extended time horizons.
Investment Thesis: Growth Story Intact but Valuation Comfort Lacking
Apollo Micro Systems' investment case rests on several compelling structural tailwinds. India's defence modernisation programme, with an allocation exceeding ₹6 lakh crores in the Union Budget and a strong emphasis on indigenisation, provides a robust demand backdrop. The company's established relationships with defence research organisations and track record in electronic warfare systems, radars, and missile sub-systems position it favourably to capture market share. The 23.28% five-year sales compound annual growth rate and 35.76% EBIT CAGR demonstrate the company's ability to scale operations and improve profitability.
However, several factors constrain the investment thesis at current valuations. The company's average return on equity of 5.82% and ROCE of 10.12% remain substantially below the cost of capital, indicating value destruction rather than creation at prevailing capital deployment rates. The surge in debt levels and negative operating cash flow of ₹75 crores in FY25 raise sustainability concerns, particularly if revenue growth moderates or working capital cycles extend further. The weak interest coverage ratio of 2.58 times on average leaves limited cushion for margin compression or revenue disappointments.
The stock's technical picture shows a "mildly bullish" trend, though the price remains below key moving averages including the 100-day (₹275.93) and 50-day (₹249.99) levels. The recent trend change from "bullish" to "mildly bullish" on October 27, 2025, at ₹285.25 suggests waning momentum. MACD indicators show "mildly bearish" signals on the weekly timeframe, whilst Bollinger Bands similarly indicate "mildly bearish" positioning, suggesting the stock may face near-term resistance.

The Verdict: Hold with Caution—Growth Story Intact but Valuation Offers No Cushion
Score: 57/100
For Fresh Investors: Not recommended at current valuations. The stock trades at 109 times earnings with a PEG ratio of 2.21, leaving minimal margin of safety despite the compelling defence sector narrative. Await a meaningful correction towards ₹180-200 levels or evidence of sustained ROE improvement above 10% before initiating positions. Patient investors may consider small allocations on sharp dips exceeding 20%.
For Existing Holders: Continue to hold with a disciplined approach. The company's strong revenue growth, improving margins, and defence sector tailwinds justify maintaining exposure, though the risk-reward has deteriorated significantly from lower levels. Consider booking partial profits (25-30% of holdings) to de-risk, particularly if the stock rallies above ₹280. Set a stop-loss at ₹220 (12% downside) to protect against adverse developments. Monitor quarterly results closely for signs of working capital normalisation and debt stabilisation.
Fair Value Estimate: ₹200-220 (20-12% downside from current levels), implying the stock has run ahead of fundamentals. A more reasonable P/E multiple of 70-80 times based on FY26 estimated earnings would suggest fair value in this range, offering better risk-reward for long-term wealth creation.
