HSR Shield — Pre-Closing Compliance Protection

This Is the Message That Cost $5.6 Million

In the XCL/Verdun/EP Energy case, deal team members coordinated on drilling, pricing, and customer contracts during the HSR waiting period. Communications like this one were traced by the FTC from start to finish. HSR Shield would have coached the employee on why this conduct violates the law, stopping the illegal coordination itself, not just the message.

Slack — #project-atlas-integration
Good news — I talked to EP's ops team this morning.
⚠️ They've agreed to halt drilling on the overlapping acreage and let us set the pricing for their customers in Basin 4 until we close.
Gun-Jumping Risk Detected

Coordinating drilling operations and customer pricing before HSR clearance may violate Section 7A of the Clayton Act. Merging parties must maintain separate, independent operations until the waiting period expires. Fines for gun-jumping violations currently reach $53,088 per day.

These Violations Were Preventable

In every case, the underlying conduct was the problem: deal team members who didn't understand where the line was between permissible planning and illegal coordination. They needed education and guardrails at the moment of action. Real-time coaching would have stopped the behavior itself.

Record Penalty

XCL, Verdun & EP Energy: $5.6 Million

Three energy companies paid a record civil penalty after their deal teams suspended drilling, coordinated on customer pricing, and exchanged daily production data during the HSR waiting period. The acquiring parties assumed operational control 94 days before the deal was cleared. All of it documented in internal communications.

DOJ Action

Legends Hospitality: $3.5 Million

The acquiror obtained beneficial ownership and exercised operational control of the target before the HSR waiting period expired. The DOJ secured a $3.5 million civil penalty, marking the first gun-jumping action brought by antitrust agencies since 2017.

Individual Action

Ryan Cohen / GameStop: $1 Million

A $1 million fine for failing to file an HSR notification and observe the waiting period when acquiring voting securities. Gun-jumping enforcement isn't limited to massive deals. The agencies will pursue individuals and smaller transactions too.

In every case, the problem wasn't just what people wrote. It was what people did. The communications documented real, prohibited conduct: premature operational control, illegal pricing coordination, unauthorized information sharing. The employees needed education on where the legal line was, and they needed it before they acted.

Real-Time Guardrails for the Most Dangerous Period of Any Deal

HSR Shield deploys SideNote's antitrust cognitive model across everyone who touches the transaction. Not just the core deal team. Executives, operations, sales, finance, integration planning. The goal is to educate employees on HSR requirements and prevent the actual prohibited conduct from occurring.

Gun-Jumping Education & Prevention

Real-time coaching when employees move toward premature operational coordination, pricing alignment, or territory assignment before HSR clearance. Employees learn why the conduct is prohibited and how to stay within legal boundaries. The goal is to prevent the underlying violation, not just catch the message.

Clean Room Compliance

Coaches employees when competitively sensitive information is about to be shared outside designated channels. Explains why information barriers exist and redirects employees to proper protocols. Reinforces the training your antitrust counsel has already delivered.

Integration Planning Guardrails

Not all pre-closing planning is prohibited. HSR Shield helps employees understand the distinction between permissible framework discussions and impermissible operational coordination, so deal teams can stay productive while maintaining genuine competitive independence.

Deal-Scoped Deployment

Activate HSR Shield for specific deal teams and timelines. Deploy across everyone who touches the transaction, not just the core team. When the deal closes or terminates, the deployment adjusts automatically.

The DOJ Evaluates Whether Your Compliance Program Actually Works

In November 2024, the DOJ Antitrust Division released updated guidance for evaluating corporate compliance programs. The guidance lays out nine elements of an effective program, including risk assessment, training and communication, and periodic review, monitoring, and auditing. Prosecutors will distinguish between "paper programs" and programs that actually detect and deter violations.

The guidance specifically asks whether companies use AI and data analytics tools for compliance monitoring, whether training is tailored to specific risks, and whether the program is regularly updated to address evolving risks. It emphasizes a culture of compliance set from the top and asks whether compliance controls actually work in practice.

HSR Shield directly addresses these requirements. It provides real-time, risk-tailored education during the highest-risk period of any deal. It monitors for the specific conduct the DOJ cares about. And it creates the audit trail that demonstrates your compliance program isn't just a binder on a shelf.

01

Scope the Deal Team

Identify everyone who touches the transaction. Not just the core deal team, but executives, operations, sales, finance, and integration planning. Anyone who could be named as a custodian in a gun-jumping investigation gets HSR Shield.

02

Activate HSR Shield

SideNote's OS-level agent begins monitoring communications across every application on deal team members' devices. The antitrust cognitive model, developed in collaboration with Big Law practitioners, coaches employees in real time when language crosses into gun-jumping territory.

03

Close with Confidence

When the deal closes, your team has maintained genuine competitive independence throughout the waiting period, and you have an audit trail demonstrating proactive compliance. If the FTC or DOJ reviews the transaction, you can show the controls were in place from day one.

What HSR Shield Looks Like During an Active Deal

Your integration lead starts drafting a Slack message to the cross-functional team: "I just got off the phone with their head of operations. We agreed to pause drilling in the overlapping acreage until we can consolidate after close." HSR Shield coaches them instantly, explaining that coordinating operational decisions during the HSR waiting period constitutes gun jumping under the Clayton Act. The integration lead reads the explanation, understands that this conduct is prohibited regardless of how it's communicated, and decides not to pursue the coordination at all.

What actually changed

The employee didn't just avoid sending a risky message. They learned why the underlying conduct is illegal and chose not to coordinate operations prematurely. That's the difference between a compliance tool and a communications filter. HSR Shield prevents the violation, not just the evidence of it.

Protection That Pays for Itself Before the Ink Is Dry

Less Than One Day's Fine

HSR Shield costs less than a single day's penalty. The XCL case cost $5.6 million. The question isn't whether you can afford this. It's whether you can afford not to have it.

Aligned with DOJ Expectations

The DOJ's November 2024 compliance guidance explicitly evaluates whether companies use technology for real-time monitoring. HSR Shield is exactly the kind of proactive tool prosecutors want to see in place.

Covers Everyone, Not Just the Deal Team

Integration planning touches ops, finance, sales, and functions far beyond the core deal team. HSR Shield deploys across everyone whose communications could become evidence.

Education That Changes Behavior

HSR Shield doesn't just flag words. It explains why the underlying conduct is prohibited and helps employees understand the legal boundaries. The goal is genuine compliance, not just cleaner communications.

On-Premises Security

Deal communications are the most sensitive material in your organization. HSR Shield runs entirely on your infrastructure. Nothing leaves your network. Nothing is stored by SideNote.

Built with Big Law

The antitrust cognitive model powering HSR Shield was developed in collaboration with leading antitrust practitioners who understand the nuances of permissible vs. prohibited pre-closing conduct.
