Is Fastly (FSLY) Fully Valued After Its Comcast Partnership?

Fastly (FSLY) is back in focus after Comcast announced a content and application delivery deal that puts Fastly’s edge software directly inside Comcast’s nationwide network for Xfinity customers.

The Comcast partnership comes at a time when interest in Fastly has already been building, with a 90 day share price return of 43.04% and a year to date share price return of 143.96%. This points to strong positive momentum despite a 30 day pullback of 16.94%.

Fastly now trades far above where it started the year, with fresh excitement around the Comcast deal already in the price. Does the current setup still offer attractive upside relative to the risks, or has the easy part of the move passed?

Most Popular Narrative: 8% Undervalued

Fastly last closed at $24.86, while the most followed valuation narrative points to a fair value of $27.00. This puts the recent Comcast excitement in the context of a thesis that leans on security and compute rather than CDN alone.

The acceleration of cloud migration and edge computing, combined with Fastly's increased product velocity (especially in Compute and adaptive observability analytics at the edge), expands the company's addressable market and underpins durable multi-year revenue growth.

See why 30 investors see Fastly as 8% undervalued.

Result: Fair Value of $27.00 (UNDERVALUED)

Still, the Fastly narrative can break if CDN revenue proves too tied to one off events or if concentrated large customers pull back usage more sharply than expected.

Hello,(I am a shareholder).I spent the summer investigating in whatever I was able to find in the press, the trustee, or legal, and comparing it to FS Benner's declaration/transcripts:press: MM has a tendancy to use facts, modify them and turn them the way they want: 100% of their claims against TPG0 is traçable factually, 80% is flawed and interpreted. Example are numerous: 11M loans banks to be paid seems right, but it has not been an issue at all, it has been paid in full. (and it happens all the time in every business...); the previous HR becoming a financial director in the article herself being attacked by TPG on the legal side; the wrong address of curator (if truly announced by TPG).Trustee: according to my research (which can be incomplete) no communication to the Nordic trustee (hereby, bond holders) has been done on a, indebtedness (late payment) > 1M€, which is their obligation by contract (clause 14.d - https://corporate.the-platform-group.com/bond/) => this is a sign of a huge lie and fraud, or the sign that there is no indebtedness > 1M€ over the whole TPG group.Legal: still awaiting for an answer, probable that I won't get it.VALUATIONYou can spent hours working the fundamentals, if they're flawed...the thesis falls.Anyway, I always substracts the badwill (that I consider non-current - you have it in the CFS) & non-controlling interests from my valuation:Earnings ~22MFCF ~40M€The financial statements are not the issue here, we are more on an cheap option on the sincerity of the accounts that a real valuation. Unfortunately, these are unverifiable elements, hence the low price./!\ Careful:the accounts are consolidated and skip the subsidiaries issues...Careful with the business model: TPG0 is a financial holding that acquire subsidiaries, hold the debt, and has no operations. 100% of the Cash Flow comes from subs' dividends => it is a risk here, more a plumber risk than an operational one, but nevertheless...The auditor is too small, and managed by the same firm than before, with 140K€/year commission => it's too low, nobody external really reviewed what Benner and his team are doing internallycapital increase do not go through the CFS, but through change in equity AND equity in the BSIf the equity stays low too long, the WACC increase will be unbearable (I have a 30% global, with a 118% on equity): diluting is expensive => TPG machine can stay broken for a while.Most of the people I talk with never saw this, while this is ESSENTIAL to Benner's business model.SEVERAL EVENTS THAT COULD CHANGE:AEP is being audited by KPMG: if Benner plays the "we will propose KPMG to our shareholders BEOY", this can increase the trust in him significantly/KPMG (or other) to validate the 2026 IFRS accounts & having a word on HGB's: though still consolidated, at least we'll know...AEP being eventually acquired: while it carries a high integration risk due to its size, they talked about it so many times, that trust goes with it.Without this combination of event, the equity is doomed to stay at this level, IMO.Do not forget to also follow the bond: with TPG's announced safe harbor plan for buyback (25% of daily exchange), it is also interesting to check this illiquid and retail market: https://live.deutsche-boerse.com/bond/no0013256834-the-platform-group-ag-8-875-24-28?mic=XFRA
