Discounted Cash Flow Valuation of Singapore Technologies Engineering Ltd (SGX:S63): Assessing Fair Value in a Post-Pandemic Engineering Landscape

In the post-pandemic era, Singapore Technologies Engineering Ltd (SGX:S63) has emerged as a resilient player in the engineering and technology sector, leveraging its diversified portfolio across aerospace, defense, and smart mobility solutions. This article evaluates the company's fair value through a rigorous discounted cash flow (DCF) model, contextualized within its industry positioning and macroeconomic tailwinds.

Financial Performance and Industry Positioning

According to a GuruFocus report, SGX:S63 reported revenue of SGD 11.28 billion in 2024, reflecting an 11.63% year-over-year increase, with net income rising 19.74% to SGD 702.26 million. The company's trailing twelve months (TTM) revenue reached SGD 11.67 billion, supported by a robust order book of SGD 28.5 billion, of which SGD 8.8 billion is slated for delivery in 2025, according to ST Engineering's FY2024 release. Segment-wise, Commercial Aerospace revenue grew 12% to SGD 4.38 billion, while Defence & Public Security surged 16% to SGD 4.94 billion, underscoring the company's strategic alignment with high-growth sectors (ST Engineering FY2024 release).

The aerospace and defense industry in Singapore is poised for significant expansion. Data from GuruFocus indicates that the aerospace and defense market is projected to reach USD 15.84 billion by 2030, growing at a compound annual growth rate (CAGR) of 11.26%. Specifically, the defense segment alone is valued at SGD 6.02 billion in 2025 and is expected to expand at a CAGR of 14.15% through 2033, driven by Singapore's defense budget, which is forecasted to reach SGD 21.6 billion by 2030 (ST Engineering FY2024 release). These trends position SGX:S63 favorably, given its deep involvement in defense contracts and R&D initiatives under programs like "Manufacturing 2030," which incentivizes dual-use technologies such as autonomous systems (GuruFocus).

DCF Model and Valuation Assumptions

To assess intrinsic value, we constructed a two-stage DCF model using SGX:S63's weighted average cost of capital (WACC) of 6.62% (GuruFocus) and a cost of equity of 7.20% (ST Engineering FY2024 release). Free cash flow (FCF) projections from 2026 to 2035 indicate a gradual increase from SGD 1.12 billion to SGD 1.77 billion, with growth rates declining as the company matures, as noted in a Webull analysis. The terminal value in 2035, calculated using a 2.4% perpetual growth rate and discounted at 7.0%, was estimated at SGD 38 billion, contributing SGD 19 billion to the present value (GuruFocus). Summing the present value of the 10-year FCF (SGD 10 billion) and the terminal value yields a total equity value of SGD 29 billion (GuruFocus).

The company's current market capitalization (as of October 10, 2025) implies a share price of SGD 8.55, while the DCF model suggests a fair value of SGD 9.36 (GuruFocus). This implies the stock is trading near intrinsic value, with a marginal 8.7% discount. However, analyst price targets, such as the SGD 8.70 estimate (GuruFocus), suggest caution, potentially reflecting skepticism about near-term cash flow sustainability or macroeconomic risks.

Key Drivers and Risks

SGX:S63's valuation hinges on its ability to capitalize on defense spending and technological innovation. The Singapore government's procurement of advanced assets-such as F-35B fighter jets and Hunter Armoured Fighting Vehicles-provides a stable revenue stream for the company's defense segment (ST Engineering FY2024 release). Additionally, its investments in smart mobility solutions align with global trends toward urbanization and sustainability.

Risks include geopolitical volatility affecting defense budgets, potential overvaluation of long-term growth assumptions in the DCF model, and operational challenges in scaling R&D initiatives. However, the company's strong order book and diversified revenue streams mitigate some of these concerns.

Conclusion

Singapore Technologies Engineering Ltd is well-positioned to benefit from the post-pandemic growth of the aerospace and defense sectors. While its current share price reflects a valuation close to intrinsic value, the DCF model and industry tailwinds suggest upside potential if the company executes its strategic priorities effectively. Investors should monitor its 2025 earnings and cash flow trends, particularly in light of its ambitious FCF projections and the broader industry's CAGR outlook.
