There could be a shortage of chocolate this Halloween, one of the biggest candy companies, Hershey, warned Thursday.

As a result, smaller monsters will likely see fewer Reese's Peanut Butter Cups, Twizzlers, and Jolly Ranchers during their candy harvest.

Company CEO Michele Buck said in a conference call disclosing the results that due to supply chain challenges, the company would have difficulty meeting demand.

She added that “particular pressures in Germany, which is facing an energy crisis as Russia cuts gas supplies and the EU aims to restrict energy imports, are at the root of the problems of the company.”

Since everyday and holiday treats are produced through the same production line, the company has chosen to focus on the first category.

“We had the opportunity to deliver more Halloween candy, but we weren't able to deliver that. And we were really producing,” Buck told the BBC.

Hershey's net sales rose more than 19% to $2.37 billion last quarter, beating analysts' estimates of $2.22 billion, according to IBES data from Refinitiv.
