    Ensure a seamless transition – without the risk.

    If your organization is expanding into multiple territories overseas, it can be difficult to decide who to turn to for advice and support. Avoid the expense of recruiting individual in-country specialists and legal teams for every international operation by partnering with IRIS Global Workforce Management.

    As a trusted global M&A HR support provider, we’re here to guide you through your transition, whether it’s organic growth, a merger and acquisition, carve-out, divestiture, spin-off or IPO. IRIS ensures a smooth integration for businesses expanding globally.

    It’s no secret that global expansion and integration presents numerous challenges to businesses. But, by working with a global specialist like IRIS, we can help you avoid risks along the way; instead, we help you make informed decisions.

    During any transition, there are a number of key considerations to take into account. Many of these center around pre-transaction due diligence. Before a merger or acquisition takes place, your organization should understand the target company’s HR status and any risks and impacts that may arise. The last thing you want is a damaged reputation and a hefty fine.

    Pre-transaction support.

    Before any due diligence action is undertaken pre-transaction, IRIS will, if required, help you decide which countries suit your business best.
