Their earnings depend on defence and railway orders, vehicle output and aftermarket demand. This list looks at three of them, HBL Engineering, SPR Auto Technologies and Talbros Automotive Components, using reported FY22 to FY26 financials and the 27 October 2026 closing prices.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Which_defence_electronics_piston_and_gasket_stocks_are_covered_in_this_list\"><\/span><strong>Which defence electronics, piston and gasket stocks are covered in this list?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans.<\/strong> This list covers HBL Engineering, SPR Auto Technologies and Talbros Automotive Components. Based on the 27 October 2026 close, HBL Engineering traded at Rs 809.95, SPR Auto Technologies at Rs 4,497.8 and Talbros Automotive Components at Rs 357.5. Their return on equity ranges from 14.0% to 36.8%, and their revenue compound annual growth from FY22 to FY26 ranges from 10.9% to 28.0%.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Why_do_defence_electronics_piston_and_gasket_stocks_have_a_strong_future_roadmap_in_India\"><\/span><strong>Why do defence electronics, piston and gasket stocks have a strong future roadmap in India?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans.<\/strong> Defence electronics, piston and gasket stocks have a strong roadmap in India because local sourcing in defence, railway safety upgrades and higher vehicle production keep widening the order pipeline for Indian engineering and component firms. The main drivers are as follows. Defence sourcing. Local production lifts orders for electronics. Engine parts. Vehicles need precise pistons and rings. Aftermarket demand. Older vehicles need steady replacements. Together these factors give the companies on this list a visible path for growth over the coming years.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_has_HBL_Engineering_performed_financially\"><\/span><strong>How has HBL Engineering performed financially?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans.<\/strong> Revenue rose from Rs 1,251 crore in FY22 to Rs 3,362 crore in FY26, a compound annual growth rate of 28.0%.
