About Roop Telsonic
Roop Telsonic Ultrasonix Limited designs, develops, manufactures and markets ultrasonic equipment: industrial ultrasonic cleaning systems (single- and multi-stage tanks, aqueous and solvent lines for automotive, aerospace, medical and precision components), ultrasonic plastic-welding machines and tooling, ultrasonic metal welding for wire harness and battery applications, ultrasonic cutting and sealing for food and textiles, and sonochemistry and processing equipment. It has manufacturing plants in Gandhinagar (Gujarat) and Mumbai and sells to automotive and auto-component makers, electronics and electrical equipment manufacturers, medical-device companies, packaging converters and research labs, with service and tooling as a recurring stream.
The business descends from Roop Ultrasonix, the Trivedi family's Mumbai ultrasonics company established in the 1970s, and its technology partnership with Telsonic AG of Bronschhofen, Switzerland — one of Europe's leading ultrasonic-welding and cleaning companies. Telsonic AG (through its holding company) owns 38.45% of the equity, while Dr Anant S. Trivedi holds 31.71% and Rupa A. Trivedi 12.08%, giving the promoter family about 44% and the Swiss partner an effective blocking stake; the remaining 18% is with other shareholders. The incorporation date shown is the group's founding era; the registry date of this entity was not retrieved.
Financials: the most recent figures retrievable are for FY23 — sales of ₹55.55 Cr and profit after tax of ₹3.82 Cr, a 7% net margin typical of a capital-equipment maker with a large service and tooling component. FY24 and FY25 accounts were not available in search snippets; the FY22 column below is an estimate at roughly 85% of FY23 and all balance-sheet and cash-flow lines are estimates built around the reported sales and profit. The share count (about 0.60 Cr of ₹10) is also an estimate — neither UnlistedZone nor Planify snippets gave it — so the implied valuation should be treated as indicative.
At UnlistedZone's ₹188 (as of 2 August 2026; lot 250; the site's 52-week high and low are both ₹188) the assumed 0.60 Cr shares are worth about ₹113 Cr, roughly 30x FY23 earnings and 2x sales. Other dealers quote lower: Planify ₹164.50 as of 20 July 2026 with a 52-week range of ₹160–₹185 and a 1,100-share minimum, and wwipl ₹165 (31 March 2025) with a 100-share lot. The UnlistedZone level is used here as the user requested; a buyer should expect to negotiate toward the mid-₹160s.
Verification status (10 Oct 2026): ISIN, rate, lot and dates are UnlistedZone, Planify and wwipl figures from search snippets (the dealer sites are blocked from this sandbox); FY23 sales and profit and the shareholding percentages are from an SBNRI pre-IPO listing; the product range and plant locations are from the company's directory listings. CIN, incorporation date, registered-office address, directors' DINs, share count, FY22 figures, balance-sheet lines and headcount are unverified or estimated.

What works
- • Technology partnership and 38.45% shareholding by Telsonic AG, Switzerland, giving access to proven ultrasonic-welding and cleaning designs.
- • Diversified industrial customer base — automotive, electronics, medical devices, packaging — with recurring tooling, spares and service revenue.
- • Profitable with ₹3.82 Cr of PAT on ₹55.55 Cr of FY23 sales and two manufacturing plants (Gandhinagar and Mumbai).
- • Demand tailwinds from EV battery and wire-harness ultrasonic metal welding and from precision-cleaning needs in aerospace and medical manufacturing.
What to watch
- • Only FY23 figures were retrievable; FY24/FY25 performance and the share count are unknown, so the ₹113 Cr implied valuation is indicative.
- • Dealer spread: UnlistedZone ₹188 against Planify ₹164.50 and wwipl ₹165 — about 14% — in a thinly traded stock.
- • Capital-equipment cyclicality tied to automotive and electronics capex, and competition from Branson/Emerson, Herrmann and Chinese ultrasonic makers.
- • Minority position behind a family-plus-Swiss-partner holding of about 82%; no dividend record was found.
