Calix (CALX) After Astound Trial And AI Wins Still Looks Undervalued

Listen to the news

Calix (CALX) is back in focus after Astound completed a trial of its 50G-PON access solution, validating multi-gig broadband speeds and AI-ready operations on the Calix One platform for residential and commercial customers.

For all the product wins and AI announcements, Calix’s share price tells a different story. The stock is at US$34.36, with a year-to-date share price return down 35.88%, while the 1-year total shareholder return has declined 44.01%. This suggests recent momentum has been weak despite these headlines.

Seize this pullback in Calix to compare it with hand-picked broadband and AI infrastructure peers in our 90 AI infrastructure stocks.

After a slide this steep, either Calix still has meaningful room to re-rate as fundamentals catch up, or the recent bounce has already used up most of the easy upside.

Most Popular Narrative: 45% Undervalued

Calix screens as heavily discounted on the most widely followed narrative, with a fair value of about $62.33 against the latest close at $34.36. This leaves the whole story hinging on whether its software and AI platform actually delivers the growth embedded in those assumptions.

The move to a cloud/software-centric, end-to-end platform continues to expand recurring revenue and gross margins. As customers more deeply adopt Calix Cloud and managed services, continued margin improvement and earnings quality should follow, helping to support higher long-term net margins and cash flow.

See why 19 investors see Calix as 45% undervalued.

Result: Fair Value of $62.33 (UNDERVALUED)

Still, the Calix narrative depends on AI uptake and international expansion playing out as expected. Rising compliance costs or slower platform adoption could quickly challenge that thesis.

Another View: What Calix’s P/E Is Telling You
