Fujitsu has declined to say how much it will contribute to the £1.8bn Post Office compensation bill, which is currently being funded by taxpayers.
A senior official acknowledged that the business has not yet allocated funds to compensate those impacted by what former prime minister Rishi Sunak called "one of the greatest miscarriages of justice in our nation's history."
Due to Fujitsu's malfunctioning computer system, hundreds of subpostmasters were prosecuted for theft and false accounting; some victims were imprisoned or had their finances devastated.
Compensation is available to those whose convictions have been overturned, however one subpostmaster was mistakenly informed they were not entitled, according to MPs on the Commons Business and Trade committee.
He informed MPs on Tuesday that the corporation was dedicated to making a contribution to the compensation plan, but that the precise amount would only be known after the company had read the findings of the official investigation into the matter.
"We will decide (a figure) when we see the report,"
he declared.
Charlie Maynard, a Liberal Democrat MP, criticized him, saying,
"This whole problem would not have happened without Fujitsu's failures."
He requested that he write to the chairman and other officials of Fujitsu asking them to come before the committee and explain "if they are not paying £1.8 billion in full, why not."
The committee's chair, Labour MP Liam Byrne, also put pressure on Mr. Patterson, claiming that Fujitsu was still "taking £1m a day from British taxpayers" in a number of government contracts.
The committee also heard testimony from a former subpostmistress who, despite being charged with the same crime as her husband, had not been found guilty.
They had to "hire a barrister to fight our corner," according to her. Although we had to pay £5,000 for his services, we were certain that we were right and that continuing the struggle was the only way to obtain justice. Despite a law intended to reverse erroneous convictions from the IT debacle, she claimed she was informed that her sentence would be overturned "only weeks ago."
How much compensation has Alan Bates received?
Sir Alan Bates has entered a multimillion- pound agreement from the UK government for his individual claim related to the Post Office Horizon reproach, reportedly worth between£ 4m and£ 5m, though the exact figure remains undisclosed.
Bates, leader of the Justice for Subpostmasters Alliance, pursued compensation through the Group Litigation Order scheme after the 2019 High Court palm, where his group's£ 58m award was reduced to about£ 12m after legal freights; he rejected before government offers he supposed too low( lower than half and a third of his£ 10m claim) before settling in November 2025.
This payout came as over £1.2 bn had been expended to further than 9,000 victims by late 2025, with Bates still intimately censuring detainments for others similar as his own 66- day stay for an original offer.
