Getty Images is the bigger company of the two, and its shareholders will own approximately 54.7% of the new entity, while Shutterstock shareholders will own 45.3%. Getty Images also owns the iStock and Unsplash brands. The company will simply be called Getty Images.

Under the terms of the agreement, the combined company will retain the Getty Images name and continue trading under the NYSE ticker symbol "GETY." Craig Peters, current CEO of Getty Images, will lead the merged entity, while Shutterstock's CEO Paul Hennessy will join the eleven-member Board of Directors.

Getty Images said on Tuesday it would merge with rival Shutterstock to create a $3.7 billion stock-image powerhouse geared for the artificial intelligence era, in a deal likely to draw antitrust scrutiny.
