The PPP was designed to help the nation's smallest, mom-and-pop shops keep employees on payroll and prevent mass layoffs across the country amid the coronavirus pandemic.

In fact, the U.S. government has allocated at least $243.4 million of the total $349 billion to publicly traded companies, the firm said.

Hundreds of millions of dollars of Paycheck Protection Program emergency funding have been claimed by large, publicly traded companies, new research published by Morgan Stanley shows.

But the research shows that several of the companies that have received aid have market values well in excess of $100 million, including DMC Global ($405 million), Wave Life Sciences ($286 million) and Fiesta Restaurant Group ($189 million). Fiesta, which employs more than 10,000 people, according to its last reported annual number, received a PPP loan of $10 million, Morgan Stanley's data showed.

At least 75 companies that have received the aid were publicly traded and received a combined $300 million in low-interest, taxpayer-backed loans, according to a separate report published by The Associated Press.

"I think you've seen some pretty shameful acts by some large companies to take advantage of the system," said Howard Schultz, former Starbucks chairman and CEO. Instead, the government should act "as a backstop for the banks to give every small business and every independent restaurant a bridge to the vaccine. And that is the money and the resources to make it through."

Statistics released by the Small Business Administration last week showed that 4,400 of the approved loans exceeded $5 million. The size of the typical loan nationally was $206,000, according to the SBA report released April 16.

The SBA awarded the plurality of PPP dollars (13.12%) to the construction industry. Professional, scientific and technical services received 12.65%, manufacturing received 11.96%, health care received 11.65% and accommodation and food services received 8.9%.

Congress approved the first-come-first-served PPP in March as part of the massive $2.2 trillion CARES Act, which at the time promised to ease some of the financial burden for many of the nation's smallest business owners. But the program ran out of money on Thursday, when the SBA announced that it was "unable to accept new applications for the Paycheck Protection Program based on available appropriations funding."
