The two non-executive directors resigned from the company because of their stance on the conflict in Ukraine.
The firm's failure to quickly condemn the Russian invasion made the positions of Sir Andrew Cahn and Sir Ken Olisa unsustainable.
Both men were thanked for their valuable guidance.
The company said it was not commenting on the question if it would continue to do business with Russia.
The directors of the company felt that they should have condemned the invasion of Ukraine by Russia.
Although this was a complex situation for the company, the firm's stance was at odds with their expectations as UK board directors.
In 2015 and 2018, Sir Andrew Cahn and Sir Ken Olisa were appointed to the board of directors, and they brought considerable experience from the world of business and technology to the table.
Both have shown strong support for the UK and have helped uphold the highest standards of corporate governance.

Ms Raimondo told the newspaper that Russia is going to be courting other countries to do an end run around sanctions.
The company was banned from acquiring technology from US companies without government approval after Donald Trump added it to hisentity list.
