Despite impressive first-week sales of 192,000 in the US, industry bosses have admitted that the LP failed to match its projected sales of 400,000, Billboard reports.
The shortfall is now said to be forecasting the overall decline in album sales worldwide.
"Teenage Dream fell short in one key area: It didn't meet first-week sales projections in the industry," said EMI boss Dominic Pandiscia.
"And that, in turn, has sparked worries that the album's performance may affect retail orders for other superstar releases due later this year."
SoundScan reports that Perry's sales for the album's entire campaign totals 5 million, 3.6 million of which is accounted for sales of the first single 'California Girls'.
Pandiscia admitted overall sales were "a thrilling accomplishment from our perspective", whereas other label executives have been quoted saying they were "shocked" when they saw the debut-week sales.
Teenage Dream has so far topped the album charts in five countries.
