Advanced Laser Technologies Will Shape Future Aerospace And Defense

Key Takeaways

• Expanding defense programs and adoption in high-growth manufacturing segments drive strong, diversified revenue and reduce reliance on any single customer or market.
  
• Operational improvements and a shift toward higher-margin verticals enhance profitability, earnings stability, and free cash flow potential.
  
• Heavy dependence on defense revenue and underperforming commercial sales heighten exposure to government budget shifts, execution risks, and potential future margin pressures.

Catalysts

Designs, develops, manufactures, and sells semiconductor and fiber lasers for industrial, microfabrication, and aerospace and defense applications.

• The rapid growth and expanding pipeline in aerospace and defense, particularly around high-power laser solutions (e.g., HELSI-2 program, DE M-SHORAD, Golden Dome initiative, and increased directed energy orders internationally), positions nLIGHT to benefit from rising global defense spending and modernization, supporting strong multi-year revenue growth.
  
• Increasing adoption of advanced laser technologies for automation, smart manufacturing, and additive manufacturing (especially in high-growth EV, clean energy, and microfabrication segments) underpins long-term demand for nLIGHT's differentiated products, providing a runway for sustained top-line expansion.
  
• Successful transition of amplifier products from R&D to scalable manufacturing demonstrates operational leverage and positions nLIGHT to improve gross margins as production volumes rise and fixed costs are absorbed more efficiently.
  
• Broadened geographic reach with new international defense customers, combined with a pivot to higher-margin verticals (e.g., additive manufacturing, laser sensing), diversifies revenue streams and reduces customer concentration risk, bolstering earnings stability and growth.
  
• Recent improvements in gross margin, disciplined operating expense management, and better working capital efficiency indicate potential for enhanced earnings and free cash flow as revenue mix shifts further toward defense and advanced manufacturing applications.

nLIGHT Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming nLIGHT's revenue will grow by 12.7% annually over the next 3 years.
• Analysts are not forecasting that nLIGHT will become profitable in next 3 years. To represent the Analyst Price Target as a Future PE Valuation we will estimate nLIGHT's profit margin will increase from -21.7% to the average US Electronic industry of 9.0% in 3 years.
• If nLIGHT's profit margin were to converge on the industry average, you could expect earnings to reach $27.8 million (and earnings per share of $0.51) by about August 2028, up from $-47.0 million today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 68.6x on those 2028 earnings, up from -27.9x today. This future PE is greater than the current PE for the US Electronic industry at 24.2x.
• Analysts expect the number of shares outstanding to grow by 3.69% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 8.13%, as per the Simply Wall St company report.

nLIGHT Future Earnings Per Share Growth

Risks

• Heavy reliance on aerospace and defense (A&D) revenue-now 66% of total sales and growing-significantly increases nLIGHT's exposure to shifts in U.S. government priority or budget allocations; a change in defense spending or delays/cancellations in large programs like HELSI-2 could have outsized negative impacts on revenue and earnings stability.
  
• The commercial/industrial segment, including microfabrication, continues to underperform year-over-year (down 9%), and management expects only limited or unsustained demand improvement; reduced diversification and persistent weakness here could increase earnings volatility and limit long-term top-line growth.
  
• The transition of key amplifier products from R&D to mass manufacturing carries execution risks; any production setbacks, quality issues, or delays in scaling could disrupt delivery into critical programs and erode gross margins during this scaling phase.
  
• Nonspecific and early-stage international wins in directed energy-while promising-remain subject to strong execution risk, regulatory uncertainties, and geopolitical tensions; difficulty converting pipeline opportunities abroad could cap international revenue growth and margin improvement.
  
• Recent improvements in gross margin benefited from a favorable business mix and above-average factory absorption, both of which management cautioned may not persist; as development gross margins normalize (~8%) and the product mix shifts, there may be downward pressure on overall gross margin, potentially dampening future net margins and operating leverage.

Valuation

• The analysts have a consensus price target of $27.417 for nLIGHT based on their expectations of its future earnings growth, profit margins and other risk factors.
  
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $310.5 million, earnings will come to $27.8 million, and it would be trading on a PE ratio of 68.6x, assuming you use a discount rate of 8.1%.
  
• Given the current share price of $26.25, the analyst price target of $27.42 is 4.3% higher. The relatively low difference between the current share price and the analyst consensus price target indicates that they believe on average, the company is fairly priced.
  
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
