Is it growing?

Mixed

Neither accelerating nor breaking down: revenue growing +12% year on year and earnings up +109% year on year, but operating margin narrowing (−4.5 points).

2 good, 1 to watch
Revenue trend+12% in a year

Trailing-twelve-month revenue vs a year earlier, from the company's own filings. Five-year pace: +1% a year.

Earnings trend+109% in a year

Trailing-twelve-month earnings per share against a year earlier. Growing faster than revenue, so margins or the share count are helping.

Margin direction−4.5 points operating

Trailing-twelve-month operating margin, 14.8% now against 19.2% a year earlier.

All from SEC EDGAR, as of Jun 30, 2026.

Where this answer is blind. These are trailing numbers from the filings, not forecasts: an acquisition or a one-off year can flatter them, so check the quarters.
