Gemstar-TV Guide International Inc. said Tuesday afternoon that its shareholders approved the company’s sale to Macrovision Corp.

More than 90 percent of shares outstanding were voted in favor of the transaction, Los Angeles-based Gemstar said in a statement.

The approval comes a day after an analyst speculated that the deal was in jeopardy. The comment sent Gemstar shares down nearly 20 percent Monday.

Moody’s Investors Service lowered Macrovision’s senior secured debt ratings April 25, citing a change in the company’s capital structure. Kaufman Brothers analyst Todd Mitchell said Monday that the downgrade “creates the perception the deal’s in question.”

Macrovision agreed to buy Los Angeles-based Gemstar for $2.8 billion in cash and stock last year. The deal is expected to close early in the second quarter.

Some shareholders in Macrovision opposed the deal, saying Gemstar would take away from the Santa Clara-based software company’s bottom line.

Shares in Gemstar closed up 2 percent to $4.14 Tuesday.
