NLIGHT, INC. (LASR) stock intrinsic value fair value estimate & owner earnings analysis

nLIGHT designs and manufactures high-power lasers used in industrial cutting and welding equipment, semiconductor and electronics manufacturing tools, and defense systems. The business runs in two segments: Laser Products (industrial and defense-related laser components) and Advanced Development (research, prototyping, and early production of next-generation laser and directed-energy technology for the U.S. government). The last several years have been a real roller coaster. Revenue peaked around $270 million in 2021 on strong industrial and telecom demand, then fell for two straight years to under $200 million in 2024 as that demand dried up, with gross margin collapsing to under 17%. 2025 marked a sharp turnaround: revenue grew 32% to $261 million, gross margin recovered to nearly 30% (39% in the Laser Products segment alone), and results have kept improving into the first half of 2026. The turnaround has been driven overwhelmingly by U.S. government and defense demand: government revenue rose from 19% of the total in 2024 to 36% in 2025, reflecting growing orders tied to directed-energy and laser-sensing programs, and named customers KORD Technologies and Raytheon each represented a meaningful share of 2025 revenue. The central issue for value here is not revenue growth, it's cash cost. nLIGHT pays a large part of its workforce in stock, averaging $25-38 million a year in stock-based compensation over the last five years. That is real, ongoing dilution to existing shareholders even though it doesn't touch the cash flow statement, so we treat it as a true cost in arriving at owner earnings, alongside the cash actually needed to keep the existing plant and equipment running (separated from the cash spent to add new capacity for growth). Once stock compensation and maintenance-level capital spending are subtracted, owner earnings per share have been negative in every year since the company's 2018 IPO except that first year, ranging from roughly breakeven to a loss of over a dollar per share, with 2025's result the best since the IPO year but still negative. That history sets a cautious starting point, and the three cases in this valuation diverge mainly on whether the 2025-2026 improvement holds: The bear case assumes the defense-driven mix shift proves temporary and the industrial side repeats the sharp multi-year downturn it has already shown twice (2019 and 2022-2024) - a realistic risk given nLIGHT does not sign long-term purchase agreements with its customers and its order backlog was flat to slightly down in 2025 even as revenue grew sharply. Under this case, owner earnings per share stay negative for most of the next decade, and the shares are worth less than nothing once the ongoing stock-based dilution is accounted for - roughly negative $2.40 per share. The base case assumes the government/defense demand keeps growing at a more moderate pace than 2025's exceptional rate (consistent with the flat backlog, which does not support extrapolating the recent growth rate indefinitely), while the margin recovery in the core Laser Products business mostly holds. Owner earnings per share turn modestly positive within two to three years and grow into the mid-single-digit range per share by year ten. We do not assume a lasting competitive moat beyond that point, since nLIGHT operates in a competitive field with larger rivals; the earning power is assumed to persist for some years on the strength of a two-decade operating history and ongoing government relationships, then fade rather than grow indefinitely. This produces a value of roughly $5.75 per share. The bull case assumes the defense ramp continues closer to its demonstrated recent pace for several more years, drawing on nLIGHT's own multi-year track record (government revenue nearly doubling as a share of sales in a single year) rather than a hoped-for market recovery, with margins expanding further as volume grows. That produces a value of roughly $13 per share. Given how much of this valuation depends on whether a very recent, one-year shift in revenue mix proves durable, the margin-of-safety price sits well below the base case, and it assumes a second year of results confirms the government-driven mix and margin gains are holding rather than reverting, as they have twice before in this company's history.
