Bangalore: Henrique de Castro, Yahoo’s chief operating officer responsible for breathing new life into the company’s falling Internet portal sales, is leaving the company a little over a year after he was hired by CEO Marissa Mayer.

Announced through a filing on Wednesday, the company failed to give a reason to his abrupt departure. But reports indicate the disagreements between de Castro and Mayer, and his failure to deliver on his promise were the contributing factors. Henrique de Castro, being Mayer’s first high-profile hire since she took the reins in 2012 was handed a handsome four-year $62 million package; he was brought in from Google specifically to revive Yahoo’s slumping ad revenues, but after more than a year now, growth is yet to be seen – the company is still trailing behind Facebook and Google.

De Castro is now set to receive a severance package in accordance with his employment offer letter and Wall Street Journal estimates it to be worth more than $42 million. In the light of his departure and with no replacement named yet, the executives that reported to de Castro will now report directly to Marissa Mayer.
