Joseph John Corso, who serves as the Chief Financial Officer for NLIGHT, INC., recently completed a series of transactions resulting in the sale of common stock valued at $3,883,826. These dispositions occurred over two days, May 19 and May 20, 2026, with the selling shares priced between $68.48 and $71.36 per unit.
The initial sale on May 19 involved Mr. Corso disposing of 20,243 shares at a weighted average price of $68.48 per share. According to the company records, this specific transaction was not discretionary; rather, it was necessary to satisfy tax withholding requirements associated with the vesting and settlement of restricted stock units. This type of sale is mandated by the issuer’s policy, commonly referred to as a “sell to cover” mechanism for covering taxes.
The following day, May 20, Mr. Corso conducted additional sales, liquidating 35,476 shares through multiple separate transactions. These dispositions were executed under the framework of a Rule 10b5-1 trading plan that he had established on September 15, 2025. The weighted average prices across these May 20 sales ranged from $68.81 to $71.36 per share.
The details of the May 20 activity include several distinct groupings of shares sold: specifically, 1,903 shares were sold between $68.31 and $69.29; an additional 12,946 shares traded at weighted average prices ranging from $69.31 to $70.31; 19,090 shares were disposed of in the range of $70.31 to $71.30; and finally, 1,537 shares completed sales between $71.31 and $71.58.
Following these reported transactions, Mr. Corso currently holds a total of 177,572 shares of NLIGHT common stock. This figure represents the combined amount of both his owned common stock and unvested restricted stock units. It is important to note that the timing of these sales comes against a backdrop of significant market movement for LASR.
The company’s stock has experienced substantial growth, having climbed to $76.43. This price point represents a remarkable 437% surge over the past year, which has elevated NLIGHT's overall market capitalization to an estimated $4.28 billion. Furthermore, recent analysis suggests that the stock may be overvalued relative to its Fair Value, as indicated by some professional research reports, placing it among companies identified on lists of highly valued stocks.
