IOA is SAFE.
From the Orlando Sentinel:
"Marvel also has various deals with the two-park Universal Orlando. The agreements governing two of Universal's hugely popular rides, The Amazing Adventures of Spider-Man and The Incredible Hulk roller coaster, appear to be virtually perpetual deals. According to Universal's filings with the U.S. Securities and Exchange Commission, Universal Orlando retains American rights east of the Mississippi River for as long as its attractions are in operation.
Universal and Marvel also have various deals for everything from merchandise sales to the theming of many other portions of the Orlando resort's Islands of Adventure theme park. When asked about Marvel's licensing deals with other companies for movie projects, Iger said Disney would honor the terms of those contracts. He did not specifically comment on Marvel's deal with Universal Orlando, nor did Perlmutter."
