Greenfiltec scores poorly, driven primarily by weak financial performance: three straight years of losses, a widening NT$210M net loss, razor-thin 5.3% gross margins, leverage above 1.0x equity with eroding book value, and negative free cash flow in five of the last six years. Technicals reinforce the caution, with the share price below all major moving averages and a negative MACD, though deeply oversold RSI and Stochastic readings suggest scope for a short-term bounce. Valuation provides no support given the negative P/E and absence of a dividend. Partial offsets include a meaningful revenue rebound to NT$635M, a return to positive gross margin, debt reduction and a far smaller cash burn — early signs of a turnaround that must still translate into profitability and positive cash flow before the risk profile improves.

Positive Factors
Revenue ReboundThe 2025 revenue rebound indicates that demand or commercial activity has stabilized after prior deterioration. While growth alone has not restored profitability, a firmer top line provides a foundation for operating leverage, better capacity utilization, and potential recovery if margins improve.
Negative Factors
Persistent Losses and Weak MarginsSeverely compressed gross margin and a deeply negative net margin show that the recent revenue rebound is not translating into earnings. The decline from roughly 29–32% gross margins in 2020–2022 suggests profitability has structurally weakened, leaving the turnaround unproven.

Greenfiltec Ltd. Financial Statement Overview

Summary

Fundamentals are weak across all three statements. The income statement (22) reflects three consecutive loss-making years, a gross margin collapse from roughly 30% in 2020-2022 to just 5.3% today, an operating margin of -24.7% and a widening NT$210M net loss. The balance sheet (34) shows leverage at 1.16x equity after debt ballooned to NT$577M, equity funding only ~41% of assets, and ROE of -42%, though debt reduction from NT$702M and improved leverage are modest positives. Cash flow (30) remains negative, with -NT$34M operating cash flow and -NT$67M free cash flow, albeit a sharp improvement from the prior year's heavy burn. The revenue rebound to NT$635M, lower debt and smaller cash burn are encouraging, but this remains a high-risk turnaround that has yet to produce profits or positive cash flow.
