Diffusion Engineers Up 3.4% After Closing FY26 With ₹1,994 Cr Order Book And 40% increase in PAT YoY

Synopsis:- Riding broad-based demand from steel, cement, mining, and railways, Diffusion Engineers Limited has reported its strongest annual performance since listing, with consolidated PAT rising nearly 40 percent year-on-year to Rs. 50.41 crore in FY26; Q4 FY26 was the standout quarter with revenues surging 38 percent and EBITDA up 40 percent, while the order book has already crossed Rs. 199.48 crore as of April 2026.

Shares of a Nagpur-based industrial engineering company came into focus after it filed audited results alongside an investor presentation for the quarter and year ended 31st March 2026. The numbers tell a consistent story: every major metric  revenue, EBITDA, and profit after tax  improved meaningfully over the prior year, with Q4 FY26 emerging as the sharpest quarter of the cycle. The company also disclosed that its order backlog has grown to Rs. 199.48 crore by end of April 2026, providing tangible near-term revenue cover.

With a market capitalization of Rs. 1,182.48 crore, the shares of Diffusion Engineers Limited were trading at Rs. 315.95 per share, up 3.40 percent from its previous closing price of Rs. 305.55 apiece. It is trading at a P/E of 23.92. 

The fourth quarter was the strongest of the year by a distance. Consolidated revenue from operations reached Rs. 141.57 crore in Q4 FY26, up 38.08 percent from Rs. 102.53 crore in Q4 FY25, and up 40.4 percent sequentially from Q3 FY26’s Rs. 100.82 crore. The revenue acceleration in the final quarter reflects a combination of higher order execution rates, improved customer demand, and better utilisation across manufacturing units, a pattern consistent with the heavy engineering segment’s tendency to bill heavily toward year-end project milestones. 

EBITDA (excluding other income) for Q4 FY26 came in at Rs. 20.69 crore, rising 39.96 percent year-on-year from Rs. 14.78 crore. EBITDA margins improved modestly to 14.61 percent from 14.42 percent in Q4 FY25  a 17 basis point expansion  suggesting that volume growth was not purchased at the expense of margins. Raw materials and manufacturing expenses rose in step with revenues to Rs. 100.84 crore, but operating leverage held. 

PAT came in at Rs. 15.97 crore, a 22.74 percent improvement over Q4 FY25’s Rs. 13.01 crore, with margins at 11.28 percent. EPS for the quarter stood at Rs. 4.29 versus Rs. 3.49 a year ago, a 22.92 percent increase. Other income at Rs. 2.91 crore was lower than Q4 FY25’s Rs. 4.96 crore  the prior year quarter had benefited from a higher non-operating income base  which is why PBT growth (17.33 percent) lagged EBITDA growth (39.96 percent) in the quarter. The underlying operating performance was, in fact, stronger than the PAT line suggests. 

For the full year ended 31st March 2026, consolidated total income from operations reached Rs. 406.63 crore, a 21.28 percent improvement over Rs. 335.28 crore in FY25. Total expenditure rose to Rs. 349.49 crore from Rs. 288.12 crore, driven primarily by higher raw material consumption at Rs. 273.61 crore.

EBITDA for FY26 stood at Rs. 57.14 crore against Rs. 47.16 crore in FY25, a 21.18 percent rise.Margins were almost exactly flat year-on-year at 14.05 percent versus 14.06 percent, a creditable outcome given raw material cost pressures, and evidence that pricing discipline and product mix management held through the year.

Profit before tax grew 38.66 percent to Rs. 65.04 crore from Rs. 46.90 crore. The acceleration from EBITDA growth (21 percent) to PBT growth (39 percent) reflects two factors: other income of Rs. 14.99 crore (up from Rs. 9.25 crore in FY25), and the turnaround in  associate company performance: the share of profit from associates swung from a loss of Rs. 1.95 crore in FY25 to a gain of Rs. 2.59 crore in FY26, a Rs. 4.54 crore swing that flowed directly to the bottom line. A one-time charge of Rs. 0.70 crore was also booked in Q3 FY26 towards the estimated impact of New Labour Codes on employee benefit provisioning.

PAT for FY26 came in at Rs. 50.41 crore, up 39.87 percent from Rs. 36.04 crore. PAT margins improved to 12.40 percent from 10.75 percent.Consolidated EPS rose to Rs. 13.50 from Rs. 9.59, a 40.77 percent jump.

Over five years, the company has compounded consolidated revenues at 21.23 percent, EBITDA at 22.48 percent, and PAT at 32.28 percent  with PAT CAGR outpacing revenue CAGR by over 11 percentage points, a sign of genuine operating leverage building over time.

Order Book

The order backlog at 31st March 2026 stood at Rs. 174.11 crore and had grown to Rs. 199.48 crore by 30th April 2026. The composition, however, has shifted sharply. Heavy engineering orders have surged from Rs. 64.60 crore in March 2025 to Rs. 142.16 crore in March 2026  more than doubling  and now represent 81.6 percent of the total backlog. Wear plates and wear parts have contracted from Rs. 26.51 crore to Rs. 22.01 crore, and welding consumables from Rs. 12.11 crore to Rs. 9.94 crore. 

The concentration of backlog in heavy engineering is both an opportunity and a risk to monitor. Heavy engineering orders carry longer execution timelines and higher project-level complexity than consumables. The company’s receivable days also expanded to 98 days in FY26 from 82 days in FY25  the highest in five years  which, combined with the heavy engineering mix, warrants attention on working capital as order volumes scale.
