Select Model

Rating:73Outperform

Price Target:JPY 2,520.00▲(11.50% Upside)

Action:reiterated

Date:10/29/26

The score is driven primarily by improving financial performance and a strong technical uptrend, supported by low balance-sheet leverage. These positives are tempered by a relatively expensive valuation (P/E 31.23) and historical volatility in earnings and cash-flow consistency.

Positive Factors

Improving profitability and revenueThe return to revenue growth alongside higher net income and operating profit indicates improved business performance after the prior-year decline. Stronger profitability can support reinvestment, reinforce financial resilience, and provide a healthier earnings base over the next several quarters.

Negative Factors

Volatile earnings historyA sharp prior-year profit decline shows that earnings have not followed a consistently stable trajectory. This volatility makes future profitability less predictable, can complicate planning and capital allocation, and means the latest improvement must be sustained before it represents a durable earnings trend.

BroadBand Security, Inc. Financial Statement Overview

Summary

Profitability improved in 2026 with net income rising and operating profit expanding, and revenue returned to growth (+4.25%) after a 2025 decline. The balance sheet is solid with low leverage (debt-to-equity ~0.20) and healthy ROE (~15%). The main offset is volatility across years (notably the 2025 profit drop) and choppy cash-flow conversion despite a 2026 rebound.
