Middle-market investment bank Lincoln International, based in Chicago, has acquired the financial advisory division of Stratus Group in Sao Paulo. Stratus will continue to operate its private equity unit. Terms of the deal were not disclosed.

The deal will allow Lincoln’s clients to benefit from increased global services, says the bank. Lincoln opened an office in Sao Paulo in September. The office will now have 10 investment bankers, increased from three. Robert Aldworth, a director at Stratus, will become a director at Lincoln.

The firm has about 300 investment bankers globally. In addition to the Chicago headquarters and Sao Paulo office, Lincoln has offices in Amsterdam, Beijing, Frankfurt, London, Los Angeles, Madrid, Moscow, Mumbai, New York, Paris, Tokyo and Vienna.
