PRESS RELEASE

Bhilai, 20[th] March, 2026: Simplex Castings Limited (BSE: 513472), India’s leading precision metallurgy and casting solutions company, today announced a significant order win from SMS Group worth ₹23.13 for supply of Coke Oven Doors . These bookings strengthen the company's order pipeline to ₹61.98 crores for the month of March 2026 , a strong business push for order inflows in the company.

Simplex remains the world's premier manufacturer of coke oven doors, and these wins prove our unmatched quality, reliability, and technological edge for Zero-Leakage Coke Oven Batteries .

Below are the Work Order’s received by the company in March 2026:

Customer Name	Order Value(in ₹Cr.)	Nature of Order
SMS Group	23.13Cr	Coke Oven Doors
ThyssenKrupp Group	13.02Cr	Coke Oven Doors
BHEL Varanasi	7.23Cr	Heavy Fabrication
Cumulative Small Orders	18.6Cr	Fabrication and Castings
Total	61.98Cr	-

These engagements are primarily characterised as trial or qualification-stage mandates with high-value customers. As a part of our strategic step, the Company views as a precursor to substantially larger ticket and high margin commitments. Consistent and superior delivery performance on these initial orders is expected to catalyse a significant step-up in repeat and follow-on business from the same clientele.

Separately, several large-scale project announcements by steel majors are anticipated in the near term and will be announced in due course by following regulatory compliance mandates and ongoing capacity expansion requirements across the sector, all of which are expected to generate meaningful incremental order opportunities for the Company. As the acknowledged global leader in coke oven door manufacturing, Simplex is uniquely positioned to capture a dominant share of this emerging opportunity set.

Mr. Ketan Shah, Chairman and Executive Director commented: “These order wins are deeply gratifying for the management of Simplex, not merely for what they add to our pipeline in quantum, but for the quality and pedigree of the customers they represent. Winning business from institutions of the calibre of BHEL and ThyssenKrupp is a direct validation of our

engineering standards, our reliability as a supply chain partner, and the trust that the global steel industry places in us.

March has historically been our strongest season for order conversions, and this year follows that pattern emphatically. What excites us beyond the current pipeline, however, is what lies ahead. The relationship flywheel, once set in motion with names like these, compounds powerfully.

On a macro level, several large steel plant projects are at advanced stages of announcement, and we are exceptionally well-positioned to participate and announce it in due course. As the world's largest manufacturer of Coke Oven Doors, we have earned that position through many decades of precision engineering and an uncompromising quality philosophy. These orders are simply the latest chapter in that ongoing story."
