(Kaieteur News) – Leader of the Opposition Azruddin Mohamed has criticised Sigma Engineers Ltd Inc., alleging the firm received $3.697 billion in government contracts just five days after its local registration, accumulating over $12.3 billion in State awards over subsequent years.

Pointing to corporate ties involving President Irfaan Ali’s brother, Mohamed Aqtar Ali, Mohamed called on state oversight agencies to launch immediate financial investigations. However, Sigma Engineers Ltd Inc. has rejected the accusations as serious misrepresentations, asserting its parent company has operated internationally since 2003, its first local contract was awarded through competitive bidding in 2026 via NPTAB, and that it has retained legal counsel to take action against the Opposition Leader.

The company stated that it was not established five days prior to receiving a government contract, explaining that its parent organisation, Sigma Engineers Ltd, has been incorporated and actively operating in Bangladesh since 2003. Addressing its local timeline, the firm stated that while it registered in Guyana on October 6, 2022, its first local contract was awarded in 2026 following a national competitive bidding process conducted through NPTAB. Regarding the President’s brother, the company stated that Mohamed Aqtar Ali is engaged strictly in a senior technical consultant capacity in Guyana and holds no affiliation with the parent company in Bangladesh.
