RE: Delphi Technologies Transaction and Integration Update

Dear Colleagues:

We’ve recently achieved some important milestones that I am excited to share.

BorgWarner and Delphi Technologies have submitted all of the merger control filings required by regulators in the countries where approval of the transaction is needed. In addition, earlier this week, Delphi Technologies filed its definitive proxy statement and scheduled its meeting at which it will ask its shareholders to approve the transaction for June 25, 2020. We continue to expect the transaction to close in the second half of 2020, subject to receipt of the approval by Delphi Technologies’ shareholders, the receipt of regulatory approvals and the satisfaction of other closing conditions.

The integration planning teams are making good progress. We are prioritizing meetings with as many of the Delphi Technologies people as possible, in support of the planning for the future combined organization. Our weekly Steering Committee meetings continue at the highest levels, and we also recently held our second full-day Executive Committee update.  We continue to use virtual technology effectively and efficiently.

In the coming weeks, we have a number of integration planning activities planned, including more talent familiarization meetings, virtual site visits, a value capture summit and a Day 1 readiness review.  The integration teams have made tremendous progress and are working steadily to ensure both companies are ready when Day 1 arrives.

I wish everyone the best in staying safe, and I’ll continue to provide updates as we  progress.
