Diamond Power Infrastructure Q2 FY26: Stellar Turnaround Masks Structural Concerns

The Vadodara-based company, established in 1992 and engaged in manufacturing conductors, cables, and transmission towers, has demonstrated impressive operational momentum in recent quarters. Revenue for Q2 FY26 reached ₹438.33 crores, marking a 45.23% quarter-on-quarter increase and 75.12% year-on-year growth. This performance represents the highest quarterly sales in the company's recent history, signalling strong demand in the power transmission and distribution sector.

For the half-year period (H1 FY26), Diamond Power reported net sales of ₹740.15 crores and net profit of ₹47.84 crores, reflecting the sustained momentum in business operations. The company's turnaround from years of losses—including a devastating ₹794 crores loss in FY17—has been gradual but noteworthy, with FY25 delivering ₹34 crores in annual profit on revenues of ₹1,115 crores.

Financial Performance: Revenue Surge Drives Profitability

Diamond Power's Q2 FY26 financial performance showcases impressive top-line acceleration combined with improved margin discipline. Net sales of ₹438.33 crores in the quarter represent not just sequential growth of 45.23% from Q1 FY26's ₹301.82 crores, but a dramatic 75.12% year-on-year expansion from Q2 FY25's ₹250.30 crores. This revenue trajectory positions the company at its highest-ever quarterly sales level, reflecting robust order execution in the power transmission and distribution sector.

Operating profitability improved substantially, with PBDIT (excluding other income) reaching ₹45.92 crores in Q2 FY26, translating to an operating margin of 10.48%. This represents a 529 basis point improvement year-on-year from 5.21% in Q2 FY25, and maintains consistency with Q1 FY26's 10.24% margin. The margin expansion demonstrates effective cost management and operational leverage, particularly notable given the company's capital-intensive manufacturing operations.

Net profit of ₹27.73 crores delivered a PAT margin of 6.33%, a remarkable turnaround from the 1.60% margin reported in Q2 FY25. The 473 basis point year-on-year margin expansion reflects not only top-line growth but also improved operational efficiency. However, the quarter also witnessed a concerning spike in interest costs to ₹9.82 crores—the highest quarterly interest burden on record—up from ₹3.69 crores in Q1 FY26, highlighting the company's elevated debt servicing obligations.

The tax rate for Q2 FY26 stood at an unusually low 3.75%, resulting in tax outgo of just ₹1.08 crores on profit before tax of ₹28.81 crores. This minimal tax burden—compared to the historical average tax ratio of 3.01%—has artificially boosted reported net profits. Investors should note that normalised tax rates could significantly impact future bottom-line performance as the company exhausts accumulated tax losses from previous years.

Balance Sheet Challenges: Negative Equity and Rising Debt

Despite the impressive quarterly earnings, Diamond Power's balance sheet reveals fundamental structural weaknesses that demand careful scrutiny. As of March 2025, the company reported shareholder funds of negative ₹878.66 crores, comprising share capital of ₹52.70 crores offset by accumulated losses (reserves and surplus) of negative ₹931.36 crores. This negative book value translates to ₹-16.67 per share, reflecting years of accumulated losses that have completely eroded shareholder equity.

The company's debt position remains elevated, with long-term debt of ₹324.86 crores as of March 2025, down from ₹393.05 crores in the previous year. Total borrowings, including short-term debt, support a capital-intensive business model requiring substantial working capital for raw material procurement and project execution. The debt-to-equity ratio, while technically negative due to the negative book value, signals financial fragility rather than strength.

Fixed assets stood at ₹1,165.04 crores as of March 2025, up from ₹1,054.49 crores in the previous year, indicating continued capital expenditure despite the negative equity position. Current assets of ₹482.92 crores supported working capital requirements, though current liabilities of ₹438.72 crores—including trade payables of ₹198.48 crores—left limited liquidity cushion. The company generated operating cash flow of ₹77 crores in FY25, the highest in recent years, providing some comfort on liquidity management.

Profitability Metrics: Weak Returns Despite Recent Improvement

Diamond Power's return metrics paint a concerning picture of capital efficiency despite recent operational improvements. The company's average return on equity (ROE) stands at 0.0%, reflecting the negative book value that makes traditional ROE calculations meaningless. With shareholder funds in negative territory, the company technically generates returns on creditors' capital rather than shareholders' equity—a precarious position that underscores the fundamental weakness in the capital structure.

Return on capital employed (ROCE) averaged negative 8.29% over recent periods, indicating that the company has historically destroyed value rather than creating it. While recent quarters show operational improvement, the five-year sales growth of negative 11.40% reflects a business that contracted significantly following the financial crisis years of FY15-FY17. The company's average sales-to-capital-employed ratio of negative 0.05 times further highlights inefficient capital utilisation.

The average EBIT-to-interest coverage of negative 4.68 times over recent years demonstrates the company's historical inability to generate sufficient operating profits to service its debt obligations comfortably. Although recent quarters show improved interest coverage as operating profits have recovered, the Q2 FY26 interest cost of ₹9.82 crores—representing 34.08% of profit before tax—remains a significant drag on profitability.

Peer Comparison: Valuation Premium Unjustified by Fundamentals

Comparing Diamond Power with peers in the Other Electrical Equipment sector reveals a stark valuation disconnect. The company trades at a price-to-earnings ratio of 206.41 times trailing twelve-month earnings—nearly five times the peer group average of approximately 43 times and significantly above the industry P/E of 46 times. This extreme valuation premium appears unjustified given the company's weak return profile and negative book value.

The price-to-book value of negative 8.94 times reflects the negative book value per share, making traditional valuation comparisons challenging. While peers like Waaree Energies and Apar Industries trade at reasonable P/BV multiples of 0.83 times and 0.69 times respectively with positive book values, Diamond Power's negative equity position places it in a fundamentally different risk category. The company's ROE of 0.0% compares unfavourably with peer average of approximately 13%, with leaders like Waaree Energies delivering 23.17% ROE.

Diamond Power's market capitalisation of ₹7,870 crores positions it as the sixth-largest company in the peer group, yet its financial fundamentals lag significantly. The company pays no dividend (last dividend of ₹1 per share was in September 2013), unlike peers such as Apar Industries which offers a 0.62% dividend yield. The elevated P/E ratio combined with zero dividend yield and negative book value creates an unfavourable risk-reward profile for investors seeking value in the electrical equipment sector.

Valuation Analysis: Extreme Premium Signals Overvaluation

Diamond Power's current valuation metrics suggest significant overvaluation relative to both historical norms and fundamental business quality. At ₹149.35 per share, the stock trades at 206.41 times trailing twelve-month earnings—a multiple that implies either exceptional growth expectations or speculative excess. The company's PEG ratio of 2.05 indicates the stock is expensive relative to its growth profile, with the five-year EBIT growth of 19.50% insufficient to justify such elevated multiples.

The enterprise value-to-EBITDA multiple of 112.74 times and EV-to-EBIT of 162.92 times rank among the highest in the electrical equipment sector. These stretched multiples reflect the market's optimism about the company's turnaround story but fail to adequately account for the structural balance sheet weaknesses and execution risks. The EV-to-sales ratio of 6.96 times appears elevated for a capital-intensive manufacturing business with historically volatile margins.

The stock's official valuation assessment categorises it as "RISKY"—a designation that has been in place since September 2023. This classification reflects the combination of negative book value, elevated multiples, and uncertain sustainability of recent profit growth. The 52-week trading range of ₹81.00 to ₹185.10 demonstrates extreme volatility, with the current price sitting 19.31% below the 52-week high but 84.38% above the 52-week low, indicating significant speculative trading activity.

Shareholding Pattern: Promoter Consolidation and Minimal Institutional Interest

Diamond Power's shareholding structure underwent significant changes in recent quarters, with promoter holding stabilising at 84.02% as of September 2025. This represents a notable shift from the 0.64% promoter holding in September 2024, reflecting substantial promoter consolidation during December 2024 when holdings jumped by 89.36 percentage points to 90.00%. The subsequent 5.98 percentage point decline in June 2025 to 84.02% appears to be a minor adjustment following the major recapitalisation event.

The promoter group is led by Gsec Limited with a 29.68% stake, followed by individual promoters Himanshu Jayantilal Shah (15.18%), Monarch Infraparks Private Limited (7.85%), and Rakesh Ramanlal Shah (6.64%). Positively, there is zero promoter pledging, indicating confidence in the company's prospects and eliminating concerns about forced selling in adverse market conditions.

Institutional participation remains minimal, with total institutional holdings of just 1.52% as of the latest quarter. Foreign institutional investors hold 1.42%, representing 11 FII entities, whilst mutual fund holdings are negligible at 0.06% across 5 mutual fund schemes. Insurance companies have no exposure to the stock. This lack of institutional interest reflects concerns about the company's financial structure and quality metrics, with sophisticated investors evidently remaining cautious despite recent operational improvements.

The non-institutional shareholding of 14.46% represents largely retail investors, whose holdings increased from 9.96% in March 2025 to 14.55% in June 2025 before marginally declining in September 2025. This retail-heavy ownership structure, combined with minimal institutional participation, contributes to the stock's high volatility and susceptibility to speculative trading.

Stock Performance: Extreme Volatility with Mixed Returns

Diamond Power's stock performance exhibits extreme volatility across different timeframes, reflecting both the company's operational turnaround and speculative trading interest. Over the past year, the stock has declined 7.81%, underperforming the Sensex's 4.79% gain by 12.60 percentage points. However, this one-year decline masks extraordinary long-term gains, with the stock delivering a staggering 226,187.88% return over five years—albeit from an extremely depressed base following the company's near-bankruptcy experience.

The six-month performance of 69.52% gain, generating 64.67 percentage points of alpha over the Sensex, demonstrates the speculative interest in turnaround stories within the small-cap space. However, the stock's beta of 1.35 indicates significantly higher volatility than the broader market, with annualised volatility of 52.35% classifying it as a high-risk investment. The risk-adjusted return of negative 0.15 over one year compares unfavourably with the Sensex's positive 0.39 risk-adjusted return.

Technical indicators present a mixed picture, with the overall trend classified as "Mildly Bullish" since October 27, 2025. The stock trades below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, suggesting weak medium-term momentum despite the recent bullish trend change. Weekly MACD shows mildly bearish signals whilst monthly indicators remain bullish, reflecting the conflicting short-term and medium-term momentum.

Delivery volumes have declined significantly, with the trailing one-month average delivery volume of 6.33 lakh shares representing a 62.99% decrease from the previous month's 17.09 lakh shares. This declining delivery participation, with delivery representing 40.38% of total volume versus 43.03% in the previous month, suggests reduced conviction amongst buyers and increased speculative trading activity.

Investment Thesis: Mojo Score of 44 Signals Caution

Diamond Power's proprietary Mojo Score of 44 out of 100 places it firmly in "SELL" territory, reflecting the fundamental disconnect between operational improvements and structural financial weaknesses. The score, which improved from "Strong Sell" (29) in mid-October to "Sell" (39) by late October, captures the conflicting signals across valuation, quality, financial trends, and technical factors.

The "POSITIVE" financial trend classification recognises the company's recent operational momentum, with Q2 FY26 delivering highest-ever quarterly sales, profits, and operating cash flows. However, this positive near-term trajectory cannot overcome the "RISKY" valuation grade and "Below Average" quality assessment. The technical trend of "Mildly Bullish" provides limited support, particularly given the stock's extreme volatility and declining delivery volumes.

Key Strengths and Risk Factors

Outlook: What to Watch in Coming Quarters

The path forward for Diamond Power hinges on the company's ability to sustain recent operational momentum whilst gradually repairing its balance sheet. Management's focus should centre on maintaining double-digit operating margins, reducing debt below ₹300 crores, and rebuilding shareholder equity through consistent profitability. The power transmission sector's growth trajectory provides a supportive backdrop, but execution risks remain elevated given the company's troubled history.

Investors should monitor quarterly results closely for signs of revenue sustainability and margin stability. Any deterioration in working capital management or spike in interest costs would signal renewed financial stress. Conversely, consistent quarterly profits exceeding ₹25 crores combined with debt reduction would gradually improve the investment case, though the current valuation leaves little room for disappointment.
