PDF Solutions (PDFS) drew investor attention after reporting Q2 2026 revenue of US$61.5 million, 19% higher year over year, reaffirming 20% full year growth guidance and highlighting a US$271 million backlog.
At a share price of US$54.44, PDF Solutions has just come off a 1-day share price decline of 2.92% after the Q2 release. However, the 7-day and 30-day share price returns of 9.38% and 19.26% point to strengthening momentum, while the 84.23% year to date share price return and 114.25% 1-year total shareholder return show that recent enthusiasm builds on a much longer upswing in investor confidence.
