Freshworks Joins S&P SmallCap 600 After Its NASDAQ Listing

On a Monday evening in early October, a short press release landed from New York with the kind of routine phrasing that index watchers know well. Freshworks Inc. (NASD: FRSH) is joining the S&P SmallCap 600. The company’s seat is vacated by a peer that is about to be absorbed by a larger one. For a company that already trades on a national exchange, it is a small but tangible marker of what comes after the listing.

Key takeaways

• Freshworks Inc. (NASD: FRSH) will replace BioLife Solutions Inc. (NASD: BLFS) in the S&P SmallCap 600.
• The change takes effect before the open of trading on Thursday, October 8, 2026.
• The opening comes from an acquisition: S&P MidCap 400 constituent Repligen Corp. (NASD: RGEN) is acquiring BioLife Solutions.
• All three companies are identified as Nasdaq-listed in the announcement.

What changed

According to the Oct. 5, 2026 announcement distributed via PR Newswire, Freshworks will take BioLife Solutions’ place in the S&P SmallCap 600 effective prior to the open on October 8. The announcement ties the swap to a pending deal. Repligen, which sits in the S&P MidCap 400, is acquiring BioLife.

The mechanics are straightforward. When a constituent is being acquired and will leave the index, the index provider needs a replacement to keep the benchmark at its set number of members. Freshworks is the replacement here. The release as provided to us does not give deal terms, a closing date or details on why Freshworks was chosen, so we do not speculate on them.

Why a NASDAQ listing is only the start

For companies weighing how to go public, the focus usually falls on the front end: the listing process, the choice of exchange, and the route taken to get there. Index membership is a different track. It is not granted by an exchange, and a listing does not guarantee it. It is a separate decision made by an index committee, which applies its own criteria on top of being national exchange listed.

That distinction matters for founders and boards planning a debut. A listing gives a company a public market. Membership in a widely tracked benchmark can change who is watching the stock and how it trades. Freshworks’ addition shows that the path from listing to index can run through events a company does not control, such as another company’s acquisition of an incumbent.

A listing opens the door to public markets, but index membership often arrives through someone else’s corporate action, not the listed company’s own.

Who is affected

Three groups are directly in the picture.

Freshworks. The company gains a place in the S&P SmallCap 600 starting October 8. Index inclusion can bring added visibility, though the effects on trading and ownership vary by company and are not described in the announcement.

BioLife Solutions. Its departure from the index is linked to the acquisition by Repligen. The announcement does not say when the deal will close or what happens to the shares.

Repligen. As an S&P MidCap 400 constituent and the acquirer, it is the other party in the transaction that triggered the swap.

Funds and products that track the S&P SmallCap 600 will need to reflect the change by the effective date. That is standard procedure for any constituent swap, and the announcement gives no specifics on it.

What to watch next

The first marker is Thursday, October 8, when the swap takes effect before the open. After that, three items deserve attention:

1. The Repligen–BioLife timeline. The index change is tied to the acquisition, so any updates on the deal’s progress are the main thread to follow.
2. Further index housekeeping. Acquisitions and other corporate actions regularly create vacancies, and more announcements of this kind are likely over time.
3. The listing-to-index pipeline. For companies considering a debut, whether by a conventional route or otherwise, index eligibility is a long-term consideration that sits alongside initial listing requirements.

The bottom line

This is a modest, procedural announcement, and it should be read as one. Its value for readers who follow exchange listings is as a reminder that a listing is a beginning, not an endpoint. Freshworks is already Nasdaq-listed; the move into the S&P SmallCap 600 adds a further layer to its public-market profile. This article is informational and is not investment advice.
