Changes to the S&P Indices: December 2025 Update

As of December 22, 2025, significant updates are on the horizon for the S&P indices. S&P Dow Jones Indices has announced that several companies will be added or removed from the S&P 500, S&P MidCap 400, and S&P SmallCap 600 indices during its quarterly rebalance. The modifications aim to maintain a balanced representation of market capitalization across these indices, reflecting their true individual market value.

Addition of Notable Companies to S&P 500

The S&P 500 index, which comprises some of the largest publicly traded companies in the U.S., will see the addition of three noteworthy firms:

• - CRH (Code: CRH) - A leading global building materials company known for its product range and sustainability initiatives.
• - Carvana (Code: CVNA) - An innovative online used car retailer that has transformed the automotive purchase experience.
• - Comfort Systems USA (Code: FIX) - A prominent provider of mechanical services with a reputation for excellence in HVAC systems.

Each of these companies has shown strong growth and is regarded as a representative of their respective sectors, namely Materials, Consumer Discretionary, and Industrials.

Companies Removed from S&P 500

In contrast, some firms will be deleted from the S&P 500, primarily due to their diminishing relevance in the small-cap market. The companies listed for removal include:

• - LKQ (Code: LKQ)
• - Solstice Advanced Materials (Code: SOLS)
• - Mohawk Industries (Code: MHK)

Changes in MidCap and SmallCap Indices

In addition to the S&P 500 adjustments, the S&P MidCap 400 and S&P SmallCap 600 indices will also experience notable changes. Several companies are being introduced, such as:

• - UL Solutions (Code: ULS)
• - Pinterest (Code: PINS)
• - Booz Allen Hamilton Holding (Code: BAH)
• - SPX Technologies (Code: SPXC)
• - Dycom Industries (Code: DY)
• - Borgwarner (Code: BWA)
• - Hecla Mining Co (Code: HL)

Meanwhile, some firms will also exit the MidCap 400, including:

• - Comfort Systems USA (Code: FIX)
• - Under Armour (Code: UAA and UA)
• - Power Integrations (Code: POWI)
• - Perrigo Company (Code: PRGO)

Completing the SmallCap Changes

On the other hand, the S&P SmallCap 600 will see new entrants such as:

• - Primoris Services (Code: PRIM)
• - Casella Waste Systems (Code: CWST)
• - Indivior (Code: INDV)
• - Hawaiian Electric Industries (Code: HE)

Removing underperforming companies like SPX Technologies, Dycom Industries, and others aims to refine the index's representation of small-cap opportunities.

Conclusion

These adjustments to the S&P indices reflect a dynamic market environment where companies are continuously evaluated based on their performance and relevance. Such changes underscore the evolutionary nature of market indices, ensuring that they accurately reflect the marketplace and create meaningful investment opportunities. Investors should keep a close watch on these developments as they could influence market trends and valuations in the near future.
