Select Model

Rating:44Neutral

Price Target:JPY 680.00▼(-3.00% Downside)

Action:reiterated

Date:08/18/26

The score is primarily held back by deteriorating financial performance, including a 2026 revenue decline, a swing to material losses, and back-to-back years of negative operating and free cash flow. Technicals add downside risk with the price below key moving averages and negative MACD. Valuation is only a partial offset due to the negative P/E (loss-making) despite a modest dividend yield.

Positive Factors

Manageable leverageDebt remains modest relative to equity, giving the company a comparatively manageable capital structure despite the recent increase. This balance-sheet cushion may provide some flexibility to address operating weakness, although sustained losses could reduce that protection over time.

Negative Factors

Revenue contractionThe latest revenue decline interrupts the company’s earlier growth pattern and suggests weaker demand, pricing, or business activity. A shrinking top line can reduce operating leverage and make it harder to absorb fixed costs, keeping pressure on earnings over the next several quarters.

Green Monster Inc. Financial Statement Overview

Summary

Fundamentals have worsened materially: revenue declined in 2026 (~-6.3% YoY) and profitability swung to sizable operating and net losses (net margin ~-19.5%) after positive results in 2023–2025. Cash generation is a major concern with negative operating cash flow and free cash flow in both 2025 and 2026. The balance sheet remains a relative support (debt-to-equity ~0.33, meaningful equity), but leverage has stepped up sharply versus prior years while returns turned deeply negative.
