Performance & Distributions
Market Pricing Multiples
Growth Story
SIIG's growth trajectory is currently in a harvesting phase, characterized by a negative 5-year average reinvestment rate of -64.19%. This indicates that the company is returning significantly more capital to shareholders than it is retaining for new projects, leading to a negative Sustainable Growth Rate of -4.48%. Revenue has faced substantial cyclical pressure, declining from 494.1 million SAR in fiscal 2022 to a TTM level of 19.9 million SAR at the parent level. While the core petrochemical segments have matured, the company is planting seeds for future capacity through the newly established Bioprotein Company, which is expected to complete its plant by the second half of 2028, representing a long-term shift toward non-traditional feed additives.
Profitability Dynamics
The company is navigating a period of value compression, with a 5-year average ROIC of 6.98% falling short of its 8.77% WACC, resulting in a negative value creation gap of -1.79%. This underperformance is largely driven by external headwinds at the joint venture level, where declining selling prices and rising feedstock costs have squeezed margins. Despite an operating margin of -2.37% at the parent level, SIIG remains a potent cash generator through its subsidiaries, evidenced by its ability to fund a 754.8 million SAR capital return and a 200.1 million SAR share buyback in 2025. The company maintains a robust cash reserve of 308.0 million SAR, ensuring it can sustain operations even as its joint ventures face temporary budgetary shortfalls.
Risk & Capital Structure
Risk Factors
SIIG's risk profile is defined by its zero-debt status at the parent level, which provides a significant buffer against rising interest rates. However, its relevered beta of 1.02 reflects a high sensitivity to global commodity cycles. Business-specific risks are concentrated in the liquidity of its joint ventures; for instance, JCP's current liabilities exceeded its current assets by 193.5 million SAR as of September 30, 2025, primarily due to capital reduction obligations. Furthermore, the carrying value of the SPCo investment is highly sensitive to valuation assumptions, where a mere 0.5% increase in the discount rate could necessitate an impairment. Regulatory risks also persist, as seen in the 20.8 million SAR final zakat assessment recently settled for the Petrochem subsidiary.
