Biography

Overview

Heather Greenfield is a partner in the Global Antitrust/Competition Practice of White & Case. Recognized in 2022 and 2021 by The Legal 500 US as one of only two "Rising Stars" nationwide in Merger Control, Heather has extensive experience representing clients in all phases of merger clearance before the Federal Trade Commission and Department of Justice, and before federal courts in litigated challenges by the government. As reported by The Legal 500 US, clients said Heather is "incredibly bright, and always finds solutions to unique problems" and further acclaimed she is "dedicated, sharp, calm."

Clients also benefit from Heather's significant experience on compliance related to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR Act) and global merger notification requirements, including in Europe, Asia, and South America. Heather has a proven track record advising clients on complex cross-border transactions that trigger filings around the world. Her expertise spans dozens of industries including technology, pharmaceuticals, health care, medical devices, semiconductors, solid waste, railroads, rental cars, construction, chemicals, and retail.

Some of her recent victories include:

  • Novasep Process SAS on a milestone FTC antitrust approval filed by Sartorius Stedim Biotech to acquire Novasep's chromatography equipment business, which was the first such approval after the FTC's new policy of imposing Prior Approval in consent decrees.
  • Hertz through its precedent-setting, immense, cross-border bankruptcy, including spin-offs and its acquisition by consortium-led Knighthead in an expedited timeline.
  • Meta (formerly Facebook) on its US$5.7 billion investment into a leading Indian ecommerce platform - Jio - combined with a strategic partnership to provide communications and payments channels to users and merchants.
  • Saudi Aramco in its US$69.1B merger with SABIC in the recent merger of the world's largest oil companies.

Heather has also successfully defended clients in non-merger investigations, and has advocated for government intervention on behalf of parties adversely impacted by proposed mergers. Clients have benefited from Heather's expertise in government investigations under Section 8 of the Clayton Act.

Heather routinely works with clients on antitrust compliance and competition-related counseling involving competitor collaborations, joint ventures, trade associations, information exchanges, and various business initiatives.

Clients also value Heather's experience in civil litigation matters, including merger litigation and defense of pharmaceutical companies in federal class action litigation.

She has authored and co-authored a number of articles and publications, including the US chapter of Merger Control, a comparative guide published by The Legal 500 (2020, 2021, 2022 forthcoming) and "Getting the Deal Through: Market Intelligence – Merger Control," a guide published by Lexology (2020, 2021, 2022 forthcoming).
