Questions

Which companies are Yankey Engineering's closest peers?
The cockpit's peer set: IRB Infrastructure Developers (IRB.NS), Nbcc (india) (NBCC.NS), Grenergy Renovables (GRE.MC), Kepco E&c (052690.KS), Penta-Ocean Construction (1893.T), DAI-DAN (1980.T), Hong Kong Zcloud Technology Construction (9900.HK), Per Aarsleff Holding A/S (PAAL-B.CO).
Is Yankey Engineering expensive compared with its peers?
On forward p/e it trades at 9.7× against a peer median of 13.6×, 4th cheapest of 18 in its peer set. For today's price to make sense, revenue must grow about 3% a year for seven years (Req g). Recent delivered growth is +33%, so the hurdle is -30 pp: the price already allows for a slowdown.
How has Yankey Engineering stock performed?
Over six months to 6 Nov 2026 the shares returned -16.0% against -17.2% for the median peer; over one year +15.5%.

How these numbers are made. Returns are close-to-close in local currency. Revenue growth and margins are trailing twelve months. Req g is the revenue growth that today's enterprise value requires for seven years at the company's own cost of capital; Delivered g is what it actually grew; the gap is the hurdle (honest precision about ±8 points, so read the ranking more than the decimal). No fair values, price targets or analyst ratings are shown, by design. Method and validation.
