EPAM is the largest of the new-generation digital engineering houses, and the second quarter of 2026 is the quarter that tests whether its AI-native repositioning has any commercial teeth. The quarter produced margin expansion that the guidance cut did not. GAAP operating margin climbed to 10.8 percent from 9.3 percent, the second straight quarter of that pattern, and revenue grew at a mid-single-digit pace. The tension is that organic constant currency growth ran at just 3.4 percent, so the growth story is thinner than the margin story, and the AI narrative is doing more branding work than revenue work.
The load-bearing move is the guidance reset, which came after a strong first quarter had supported a wider band. Management narrowed full year 2026 revenue growth to a low-single-digit range. Non-GAAP diluted EPS guidance was cut to a $13.08 to $13.24 band. The third quarter guide implies growth of 1.7 percent at the midpoint, and that deceleration into the summer is the number the next two prints either confirm or reverse.
The print itself is clean, and the capital return is doing real work. GAAP diluted EPS rose 26.3 percent to $1.97. The company spent $85 million buying back shares in the quarter, part of a $409 million first half repurchase. The program sits under a $1 billion authorization that includes a $300 million accelerated share repurchase that closed in April. The forward question is whether organic growth can re-accelerate above 3 percent before the buyback math starts to outrun the top line.
