Align Technology (ALGN) Could Be 17% Undervalued As New Guidance Tests Valuation

Align Technology guidance update and what it could mean for investors

Align Technology (ALGN) issued new earnings guidance for the third quarter and full year 2026 on July 29, alongside second quarter results and a buyback update, giving investors fresh data points to assess the stock.

See our latest analysis for Align Technology.

Guidance for softer third quarter revenue, one time restructuring charges and the recent product updates around Align Technology’s digital platform appear to be feeding into mixed sentiment. The 1-year total shareholder return is 23.8%, but the 3-year total shareholder return has declined 51.7% and the 5-year total shareholder return has fallen 74.9%. This suggests long term momentum has faded even as the year to date share price return of 10.8% points to some recovery.

Another view on Align Technology’s valuation

The first narrative frames Align Technology as 17.3% undervalued based on analyst earnings forecasts and a target P/E of 24.8x. Yet on today’s numbers, the stock trades on a 29.9x P/E, roughly in line with its fair ratio of 29.9x and slightly above the US Medical Equipment industry at 29x. That suggests the market may already be pricing in a fair amount of optimism. Is this a margin of safety, or a sign that expectations leave less room for error?
