TTM Technologies, Dutch Bros, Advanced Energy Industries, and American Healthcare REIT Set to Join S&P MidCap 400; Others to Join S&P SmallCap 600

TTM Technologies, Dutch Bros, Advanced Energy Industries, and American Healthcare REIT are set to join the S&P MidCap 400, marking a significant shift in their market positioning. These changes, effective January 30 and February 2, 2026, arise from a series of acquisitions that will see incumbents like Civitas Resources, PotlatchDeltic, and Comerica leave the index.

TTM Technologies (NASDAQ: TTMI), a leader in advanced electronics manufacturing, will transition from the S&P SmallCap 600 to the MidCap 400, replacing Civitas Resources (NYSE: CIVI), which is in the process of being acquired by SM Energy Co. (NYSE: SM). Similarly, Dutch Bros Inc. (NYSE: BROS), the popular coffee chain, will step in as PotlatchDeltic’s successor amid its acquisition by Rayonier Inc. (NYSE: RYN).

Advanced Energy Industries (NASDAQ: AEIS) will also make the move to the MidCap 400, displacing Comerica (NYSE: CMA) as it gets acquired by Fifth Third Bancorp (NASDAQ: FITB). Meanwhile, American Healthcare REIT Inc. (NYSE: AHR) will fill the spot left by Cadence Bank (NYSE: CADE), which is being acquired by Huntington Bancshares Inc. (NASDAQ: HBAN).

Simultaneously, the S&P SmallCap 600 will witness the arrival of Amneal Pharmaceuticals (NASDAQ: AMRX) replacing TTM Technologies, while Apellis Pharmaceuticals (NASDAQ: APLS) and LegalZoom.com (NASDAQ: LZ) will take the spots of Advanced Energy Industries and Elme Communities (NYSE: ELME), respectively. These adjustments reflect ongoing consolidation trends in various sectors and are poised to enhance the representation of growing companies in these pivotal market indices.

The recent announcement by S&P Dow Jones Indices regarding the inclusion of TTM Technologies, Dutch Bros, Advanced Energy Industries, and American Healthcare REIT in the S&P MidCap 400 is significant for investors. These companies represent key sectors that are poised for growth, which could offer compelling investment opportunities.

**TTM Technologies (NASDAQ: TTMI)** operates in the information technology sector. As the demand for advanced electronics components continues to increase, driven by technologies such as 5G and the Internet of Things, TTM is well-positioned to benefit from this trend. Investors should monitor its earnings growth and profit margins, especially as the company transitions into the MidCap 400.

**Dutch Bros (NYSE: BROS)**, a coffee chain, appeals to younger consumers with its vibrant brand and unique offerings. The transition to the MidCap 400 could catalyze investor interest, enhancing its market visibility. Given the coffee segment's growth potential, particularly in drive-thru formats, Dutch Bros may offer strong growth prospects, albeit with some volatility often seen in consumer discretionary stocks.

**Advanced Energy Industries (NASDAQ: AEIS)**, another MidCap inclusion, operates at the intersection of renewable energy and technology. As the transition to sustainable energy accelerates globally, the company’s focus on power conversion and management will likely place it at a competitive advantage. Investors should analyze its technological advancements and growth strategies in this rapidly evolving market.

**American Healthcare REIT (NYSE: AHR)** benefits from the robust demand for healthcare real estate, especially post-pandemic. With increasing investments in healthcare infrastructure, this REIT's inclusion in the MidCap 400 could attract institutional investors, enhancing its valuation.

In contrast, TTM and Advanced Energy will be removed from the S&P SmallCap 600, prompting near-term pricing adjustments. Investors should weigh these changes carefully, considering both market sentiment and fundamental drivers within each sector. Monitoring upcoming earnings reports and management guidance will be crucial in evaluating future performance.
