Nova Ltd. (NASDAQ:NVMI) grew second-quarter revenue 15.9%, but diluted GAAP earnings per share increased only 2.8%. The gap matters for investors in the semiconductor-measurement supplier: business expansion creates value per share only after margins, financing effects and the share count have taken their portion. Nova ranked second in our recent 20-year performance list. Discover the sole stock that compounded faster in the screen, and the semiconductor names Nova outpaced.
The August 6 report showed revenue of $255.0 million and net income of $75.0 million, versus $220.0 million and $68.3 million a year earlier. Earnings rose 9.8%, already slower than sales, before the larger diluted share base further reduced per-share growth.
For illustration purposes only: semiconductor manufacturing.
Hedge-fund participation increased to 25 holders in Q2 2026 from 22 in Q1, according to Insider Monkey’s database. Renaissance Technologies reduced its shares roughly 13%.
Dilution absorbed part of the operating progress
Weighted-average diluted shares increased to 34.450 million from 32.053 million, a 7.5% rise. This includes potential shares, rather than only stock actually issued. Convertible-note accounting also adjusts the earnings numerator, so reported net income divided by diluted shares does not fully reconcile EPS.
Gross margin also fell to 56.5% from 57.8%. Operating income still increased 16.1%, helped by expenses growing more slowly than sales, but net financing income declined.
Operating profit increased $10.5 million. Lower net financing income absorbed $2.3 million of that gain, and the tax bill rose $1.6 million, leaving the $6.7 million increase in net income. This bridge matters because the quarter’s slower net-profit growth does not mean the equipment business failed to generate operating leverage.
Measurement demand must translate into ownership gains
The favorable case is that expanding demand supports enough operating income growth to outpace dilution. The competing case is that growth continues while each existing share receives a smaller portion of the benefit.
Nova’s measurement systems address a practical manufacturing problem: as structures become more complex, customers need to measure them accurately enough to control production. More measurement work per wafer can expand the opportunity even without equivalent growth in wafer volumes. But technology adoption creates development costs before every customer ramps production.
At the October 8 close, Nova traded near 44.1 times trailing earnings. That multiple already prices the per-share result, making dilution central to the growth investors actually receive.
If the relevant diluted earnings numerator grew 15% while diluted shares rose another 7.5%, EPS would grow only 7.0%, since 1.15 divided by 1.075 equals 1.070. With no share-count growth, the same earnings increase would deliver the full 15%. This is a simplified sensitivity with convertible accounting held consistent, not a forecast of future issuance. Our Lam Research–KLA comparison tests whether faster chip-equipment growth justifies paying more for cash generation.
Nova’s operating progress is stronger than its EPS headline. Matching that growth per share requires diluted earnings growth to offset share-count expansion; dilution need not stop for EPS to accelerate.
