Darien Shanske (UC-Davis; Google Scholar) & David Gamage (Indiana-Maurer; Google Scholar), Why States Should Conform to the New Corporate AMT, 107 Tax Notes St. 601 (Feb. 13, 2023):

This Essay argues that U.S. state governments should conform to the recently enacted federal corporate alternative minimum tax, so as to raise revenues by combatting corporate profits shifting. This Essay also offers suggestions for implementation.

Conclusion
We understand that most states are not likely to be clamoring for more revenue in the short term. Nevertheless, conforming to the new CAMT is clearly a sensible, progressive, fair, and administrable option that can raise substantial revenue. Additional revenue will almost certainly be needed at some point, and we recommend conforming to the new CAMT as a promising option for raising that revenue. More fundamentally, as the ongoing ferment around the OECD pillars and CAMT demonstrates, we agree with the broader policy consensus that the highly mobile capital of large multinationals should be subject to closer to an equivalent rate of tax as their less-mobile domestic competitors.
