Is Wall Street Wrong About the IRA?

Is Wall Street too sanguine about the House of Representatives’ proposal to gut the Inflation Reduction Act? When the House Ways and Means Committee unveiled its language on the law on Monday — phasing out tax credits, implementing strict restrictions on business relationships with Chinese companies, and altering when projects are eligible for credits — some investors responded to the cutbacks by driving up the prices of some clean energy stocks.

The residential solar company Sunrun traded up on Tuesday by 8.6%, and the American solar manufacturer First Solar was up over 22%. (Stock movements on Monday were largely in response to the pause of the U.S.-China trade war, also announced that morning.)

“The early drafts of a Republican tax and spending bill weren’t as bad for renewables as feared,” wrote Barron’s. Morgan Stanley analysts used the same language — “not as bad as feared” — in a note to clients on the text. “Industry was bracing for way worse,” Don Schneider, the deputy head of public policy for Piper Sandler and a former Republican staffer on the Ways and Means Committee, wrote on X.

While many analysts — and, to be honest, journalists at Heatmap — have issued dire warnings about how the various provisions of the Ways and Means language could together make much of the IRA essentially impossible to use, even before the tax credits phase out, investors on Wall Street and in Washington seem to have shrugged them off. Some level of cutting was all but inevitable, and “not as bad as it could have been” is reason enough to celebrate — plus there’s also “it’ll probably change, anyway.”

There’s something to this. A group ofmoderate Republicans criticized the language on Wednesday as too restrictive, specifically citing changes to three overarching features of the tax credits: when projects would be eligible for tax credits, where companies are able to source components and materials, and whether companies are allowed to freely buy and sell tax credits generated by their projects. (Wouldn’t you know it, these complaints largely echo what Heatmap has written in the past few days.)

In the Senate, meanwhile, Republican Kevin Cramer of North Dakota, said that the text as written would be too damaging to advanced nuclear and enhanced geothermal generation. The phase-out timelines in the Ways and Means language are “too short for truly new technologies,” Cramer told Politico.

Pavan Venkatakrishnan, an infrastructure fellow at the Institute for Progress, told me that he expects the bill to evolve in a way to meet the concerns of Senate Republicans like Cramer.

“Given considerations both political and procedural, like the more flexible reconciliation instructions Senate Finance is afforded relative to House Ways and Means and the disproportionate impact current text entails for technologies Republicans traditionally favor, like nuclear, geothermal, and hydropower, I think it’s fair to say that this text will change over the coming weeks,” he said.

Finally, days after the Ways and Means committee made its thinking public, Wall Street seems to be catching on to the implications. The new foreign entities of concern rules pose a particularly huge danger to the renewable energy sector, according to Jefferies analyst Julien Dumoulin-Smith, and especially to energy storage, which would be the key provider of reliability on a renewable-heavy grid. Energy storage looks to account for almost 30% of new generator additions this year, according to the Energy Information Administration.

“We think the market got it wrong for storage,” Dumoulin-Smith wrote in a note to clients. The market has yet to “digest and fully interpret the implications of proposed tariff and tax policy, which as currently written do not bode well for storage,” he said. The foreign sourcing language “is more restrictive than initially thought, with some industry stakeholders calling the proposal a near repeal on IRA.”

The storage supply chain is intensely entangled with China. Many companies, including Tesla,have been forced to disclose to investors just how reliant they are on China for their storage businesses.

China alone accounted for 70% of battery imports in 2024, according to industry analysts at BloombergNEF, over $14 billion worth. About a quarter of the metals used in battery manufacturing — especially graphite — came from China, BNEF figures show. For specific battery chemistry like lithium iron phosphate, which is popular for stationary storage products, the supply chain is essentially 100% Chinese.

Wall Street revenue and profit estimates “do not adequately capture the extent of risks” facing the U.S. storage industry, Dumoulin-Smith wrote. The storage company Fluence’s stock fell around 1.5% today, and is down over 5.5% since close of trading on Monday, as the market began to digest the House language.

It is possible that the foreign sourcing rules will be loosened and phase-outs for tax credits and transferability lengthened, Venkatakrishnan told me, but not in a way that would endanger the overall structure of the bill. Cuts to the Inflation Reduction Act are a key source of revenue for the Republican bill-writers to ensure as many of the tax cuts they want can fit within the budgetary scope they’ve given themselves.

“Any adjustments will be made with an eye toward ensuring budgetary offsets are sufficient to enable success of the broader enterprise,” Venkatakrishnan said. In other words, as much as some lawmakers may want to see these tax credits preserved, ultimately, they’ve got to pass a bill to ensure Trump’s tax cuts stick around.
