    We’re pleased to partner with Lexology and Global Competition Review to present this timely and practical webinar. Our Antitrust & Competition team will explore how the new Hart-Scott-Rodino (HSR) rules are reshaping the regulatory landscape for M&A transactions and what legal and deal teams have learned in the first six months of implementation. With significant new filing requirements, expanded document production obligations and a more complex prefiling process, companies need to adjust not only how they approach filings, but also how they prepare far in advance of any potential deal.

    We will examine what has changed, whether the new rules are delivering on their promise of more efficient reviews, and what steps legal departments can take today to stay ahead of the curve.

    Key Takeaways

    • Understand the expanded HSR filing requirements, including detailed narratives, prior acquisition disclosures and broader document production
    • Gain insights into early filing trends and agency enforcement posture since the rules took effect
    • Learn practical strategies for in-house teams to streamline compliance, coordinate with deal teams and prepare for Second Requests
    • Hear what the first six months reveal about the long-term future of HSR reform and how to build durable internal processes in response
    • Explore what is next, including state-level “baby” HSR regimes and increased involvement by state attorneys general

    Whether you are actively planning a transaction or simply want to be better prepared, this session will equip you with the tools to navigate the new HSR regime with confidence.
