What steps are needed for a share purchase merger in Uganda, and how long does due diligence take?

Share transfer arises from a legal sell or purchase of shares from another Company which is allowed in Uganda. You need a lawyer to first review the compnay memorandum and articles of association and then draft a share purchase agreement with he terms of share sale. Just like any other contract. The company has to convene a meeting and approve this transaction and thereafter effect the changes to the company incorporation structure after a share valuation is conducted. As for mergers, a lot of factors have to be considered which your email does not details. The new Anti-competition Act also requires that an approval is obtained before a merger is effected. As for the due diligence, you have to look at matters like business as a going concern, tax and litigation matters, statutory compliance issues, third party interest on the shares for mortgages (SIMPA) etc before any purchase of company shares.
