Index removals put nLIGHT back in focus for investors

nLIGHT (LASR) has been removed from multiple Russell indices, including the Russell 3000E, Russell Microcap, and Russell 2000 Value Benchmark. This change is prompting index funds to rebalance and may reshape short term trading flows.

Following the index removals, nLIGHT's share price has come under pressure in the short term, with 1-day and 7-day share price returns falling 9.63% and 15.24% respectively. This is in contrast to its 1-year total shareholder return of 211.73% and 3-year total shareholder return of 293.66%, which indicate that the longer term momentum has been strong.

After a swift pullback driven by index removals, nLIGHT now sits at a very different entry point compared to recent weeks. Is it more appropriate to commit capital at this level, or to wait until there is a clearer valuation cushion?

Most Popular Narrative: 31.7% Undervalued

On the most followed narrative, nLIGHT's fair value of $86.43 sits well above the last close of $59.01, which puts a spotlight on what is driving that gap.

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.

Want to see what kind of revenue path and margin lift has to line up for that valuation to work? The narrative leans on compound growth, a profit shift, and a rich future earnings multiple that is usually reserved for market standouts. Curious which assumptions really move the fair value dial here and how tight the margin for error looks?

Result: Fair Value of $86.43 (UNDERVALUED)

However, the nLIGHT narrative could be knocked off course if defense budgets or key programs shift, or if weaker commercial demand keeps earnings more volatile than expected.

Another View: What nLIGHT's Price To Sales Ratio Is Signalling

The fair value narrative for nLIGHT leans on future earnings, but today the stock trades on a P/S ratio of 11.5x. That is far above the estimated fair ratio of 2.8x, the US Electronic industry at 2.8x, and peers at 2.3x, which points to meaningful valuation risk if expectations reset.
