Voting matters and shareholder proposals

Risk oversight and compliance

• The parties identify risks including failure to secure stockholder or regulatory approvals, competing proposals, litigation, integration challenges, and merger benefits or synergies not arriving as expected.

• The merger exchange ratio is fixed and will not adjust for changes in either party’s share price; the parties also cite potential effects from transaction-related debt and business disruption.
