On 15 September 2023, our Tech Week that Was column referred to the trading halt requested on 14 September by 4DS Memory.

We did not intend to suggest in this article that 4DS Executive Chairman, David McAuliffe, had engaged in any wrongdoing in connection with the circumstances relating to the request.

If any readers understood the article as suggesting that he had, we accept unequivocally that this is not the case, and unreservedly withdraw any such suggestion.

We apologise to Mr McAuliffe for any harm caused.
