Apple Inc. has issued unusual and significant stock bonuses to some engineers in an effort to retain talent, looking to stave off defections to tech rivals such as Facebook owner Meta Platforms Inc.

Last week, the company informed some engineers in silicon design, hardware, and select software and operations groups of the out-of-cycle bonuses, which are being issued as restricted stock units, according to people with knowledge of the matter. The shares vest over four years, providing an incentive to stay at the iPhone maker.
