I also appreciate that they staff appropriately and thoughtfully and are readily available to provide timely advice. This is truly a stellar team.’

‘Logan Breed is top notch – he is a consummate professional and exceptionally knowledgeable in this field.’

‘The firm helped us with an on-again off-again merger that required FTC approval and the Hogan Lovells team seamlessly picked up our file each time with no loss (or very little loss) of momentum upon each iteration of the deal. For perspective, this deal took years not weeks or months and the Hogan Lovells team remained mostly constant throughout, which was a benefit to us and a credit to the firm.’

‘The Hogan Lovells lawyers were often asked by our management team to make predictions as to how the FTC would react to the filings made (in terms of timing for an FTC response as well as the substance of an FTC response) and the Hogan Lovells’ predictions rang true in almost all circumstances. Given the dependability of their advice, we were able to make accurate and informed business decisions that helped our deal gain FTC approval and later proceed to closing.’
