See what the community is saying about Sumitomo Electric Industries TSE:5802 Earnings & Revenue History as at May 2026 TTM earnings growth hits 90.7% Trailing twelve month earnings grew 90.7% year on year, with basic EPS moving from ¥248.47 to ¥473.78 and net income (excluding extra items) rising from ¥193,771 million to ¥369,508 million on revenue of ¥5.1b. What stands out for the bullish view is how this earnings jump sits alongside a five year average earnings growth of 25.5% per year, which heavily supports the idea of a solid longer track record even if future forecasts are softer. Bulls often highlight that earnings rising from ¥193,771 million to ¥369,508 million on a revenue base growing from ¥4.7b to ¥5.1b can point to better profit conversion rather than just top line expansion. At the same time, the move in basic EPS from ¥248.47 to ¥473.78 gives bulls a concrete per share figure to point to when they argue that recent performance backs their optimism. Margins at 7.2% bring profit quality into focus Trailing net profit margin is 7.2% on ¥5.1b of revenue, compared with 4.1% a year earlier, which means more of each yen of sales is currently dropping to the bottom line. Critics highlight that while this margin move is supportive, forward expectations for earnings growth of about 7.5% per year and revenue growth of about 3.4% per year are more muted than the past 90.7% earnings increase, which challenges very aggressive bullish stories. This gap between a 90.7% trailing earnings rise and 7.5% expected annual growth can make bearish investors question how repeatable the latest margin level is if revenue is only expected to grow around 3.4% per year. Because net profit margin improved from 4.1% to 7.2% while forecasts step down to mid single digit growth, skeptics may frame FY 2026 as a strong base year rather than a new normal that automatically extends. Valuation split between DCF and 27x P/E At a share price of ¥12,775, the stock sits about 16.4% below the DCF fair value of ¥15,286.87, yet trades on a 27x P/E compared with 14.3x for peers and 9.6x for the Japan Auto Components industry, and has shown higher price volatility than the broader Japan market over the past three months. What is surprising for many investors is that a DCF signal suggesting the stock was trading below DCF fair value by about 16.4% coexists with a P/E that is almost 2x the peer average and nearly 3x the industry average, which gives both bullish and bearish narratives data to lean on. Supporters of the bullish angle may focus on the discount to the ¥15,286.87 DCF fair value and the 90.7% trailing earnings growth when arguing that the 27x P/E is being backed by recent performance rather than only by hope. Bears instead tend to emphasize that a 27x P/E versus 14.3x for peers and 9.6x for the wider industry, combined with higher recent share price volatility, leaves less room for disappointment if earnings growth slows toward the 7.5% forecast range.
