Baffled C-Suites Are a Fresh Hurdle for Markets

Delta Air Lines Inc. and the parent of Frontier Airlines recently yanked earnings guidance for 2025, with JPMorgan Chase & Co. Chief Executive Officer Jamie Dimon saying that he expects “to see more of that.” United Airlines Holdings Inc. took the unusual step of offering two profit scenarios since the environment “is impossible to predict this year with any degree of confidence.” It isn’t just the airlines. JD Sports Fashion Plc warned analysts to not even ask about tariffs — “we’re not going to answer” — and Levi Strauss & Co. said its team was still trying to figure out the impact of the levies.

The first-quarter earnings season is only just beginning in earnest, but investors are already preparing for the possibility that they may end up getting a lot less forward-looking information than they’re used to from top executives.

On today’s Wall Street, corporate guidance is usually front and center in quarterly earnings reports and management calls. In many cases, it’s become the main event of the quarterly tradition, more important than the actual financial results, which are seen as yesterday’s news. For some four decades, the proliferation of corporate guidance has mostly been a one-way street. But lately, President Donald Trump’s unpredictable economic agenda is making it close to impossible for many companies to issue a reliable outlook.

The past two weeks have been especially jarring. Since Trump’s “Liberation Day” tariff announcement, corporate America has been absorbing a policy that could yet drive tariffs to the highest in a century, potentially upend global supply chains, freeze planned capital expenditures and — depending on what ultimately happens with consumer prices — maybe set off a retail retrenchment.

Even if the administration had laid out a reliable roadmap for the policy shift, the upheaval would still be difficult to forecast, since it’s never been tried before in a modern developed economy as important as the US. But to make matters worse, the rules of the game keep changing by the day. Many countries and a few key industries have already earned temporary reprieves, but the medium-term uncertainty continues to run extremely high.
