Shares of MoviePass’s owner crashed as much as 30 percent as it revealed it has less than a month of cash in the bank — even as the company’s chairman told The Post in an exclusive interview that he’s not worried.

The controversial subscription service said in a Tuesday securities filing it had just $15.5 million in available cash as of April 30. That means MoviePass is on track to run out of cash in a matter of weeks, as it has been burning through cash at a rate of $21.7 million a month, or $725,000 per day.

MoviePass, which sold $150 million in new stock last month, “will need additional capital to offset our monthly cash deficit,” the company warned in its filing. The company said it also has $27.9 million in cash deposits from longer-term memberships that it can’t immediately access.

Shares of MoviePass’s parent company, Helios & Matheson Analytics, were recently off 28 percent at $1.52.

“I’m not worried about the cash burn at all,” Helios & Matheson chairman Ted Farnsworth told The Post on Tuesday.

Farnsworth noted that the company has registered to sell as much as $300 million in new stock to raise additional funds in the coming months, and that it’s exploring raising money through both debt and equity. He declined to elaborate.

Tuesday’s filing came on the heels of a late Monday conference call held by AMC Theaters, whose chief executive, Adam Aron, told analysts that MoviePass in April paid an average of $12.02 per ticket to AMC as its subscribers went to the movies an average of 2.75 times.

“Now, I took the calculator out and I multiplied 2.75 times $12.02 and I got to a number that was considerably larger than $9.95,” Aron said.

The theater exec was referring to MoviePass’s movie-a-day deal for a flat fee of $9.95 — a business model he repeatedly called “unsustainable” given the cash it’s burning.

Farnsworth, however, disputed AMC’s figures, saying MoviePass members had actually visited the chain an average of 1.8 times in April.

He added that MoviePass has slashed that number to 1.13 since it began cracking down on users who have been sharing their memberships and watching the same movie more than once.

“Anything below 1.5 for us is great, because you can make it up with other revenues” from marketing deals and other corporate tie-ins, Farnsworth told The Post.

“I don’t know how they come up with their numbers,” Farnsworth added. “I don’t know how they can track our data.”

Helios recorded a $150.8 million loss in 2017, largely from MoviePass, it said in its annual report released last month.

The all-you-can-watch service said Tuesday it’s hoping to stem the bleeding by forbidding users from seeing films more than once and upgrading its app to make sure that subscribers can’t share their accounts with others.

“We believe these measures enable us to reduce our cash deficit during the first week of May 2018 by more than 35%,” the filing reads.

AMC’s Aron said his skeptical views of MoviePass “have not changed one iota” since last August, when it said MoviePass is “not in the best interest of moviegoers” in response to the service dramatically slashing its monthly rate that month from $50 a month.

“Just as we were fearing that the MoviePass price point was unsustainable in August, we have the same questions today,” Aron said. “$9.95 for up to 30 or 31 movies a month is not enough money to spread around MoviePass, Hollywood studios and theater operators.”

Farnsworth shot back: “My question to him is: They’ve got $8 billion in debt. They’re one of the most leveraged companies out there. We have zero debt. Who’s more sustainable?”

MoviePass has seen its user base balloon to nearly 3 million from 20,000 in less than a year.

Last week, it brought back its movie-a-day deal after briefly suspending it, a move it made last month that stoked speculation it was caving under the pressure of losses.
