  • Jan 06, 2025

G4S recently announced the appointment of Michael Leahey to the position of chief financial officer. Leahey joins G4S from parent company Allied Universal®, where he served as vice president of corporate finance. Leahey will report to Tim Brandt, Allied Universal’s global chief financial officer and Ashley Almanza, executive chairman of G4S/Allied Universal International.

Allied Universal, the world’s leading security and facility services provider, acquired G4S in 2021 and operates using the G4S name outside of North America.

In his most recent position with Allied Universal, Leahey was responsible for global financial planning and analysis where his role focused on: developing annual and long-term financial plans; facilitating strategic decisions backed by optimal investment plans; setting capital markets philosophy; and designing frameworks that facilitate critical decision support. His professional past includes positions of increasing responsibility in investment banking with Wells Fargo Securities, as well as with private equity firm Parallax Capital Partners and several other private equity controlled private and public companies. Leahey graduated from the University of San Diego with a bachelor of business administration degree in finance.

“Working with Mike over the past four years, I’ve been impressed by his strong work ethic, financial acumen and strategic thinking,” said Tim Brandt. “He has been able to build excellent working relationships across the various organizational functions and is an impactful leader who develops, mentors and coaches staff to drive performance. I have no doubt he’s going to make an outstanding CFO and play a pivotal role in advancing G4S’s long-term financial and operational objectives.”

Ashley Almanza commented, “We’re excited to welcome Mike to G4S and our international headquarters in London. Having overseen the global financial planning and analysis activities at our parent company, he brings to bear a unique understanding of G4S and the financial and operational complexities associated with managing a global security business. I am confident that Mike will hit the ground running and be instrumental in helping deliver value to our stakeholders.”

Almanza continued, “I would also like to thank Chris Simpson for assuming the CFO role on an interim basis over the past several months as we conducted our search.” Chris will return to his role as International Group Controller.

    Years ago, it would have been significantly more expensive to run an analytic like that — requiring a custom-built solution with burdensome infrastructure demands — but modern edge devices have made it accessible to everyone. It also saves time, which is a critical factor if a missing child is involved. Video compression technology has played a critical role as well. Over the years, significant advancements have been made in video coding standards — including H.263, MPEG formats, and H.264—alongside compression optimization technologies developed by IP video manufacturers to improve efficiency without sacrificing quality. The open-source AV1 codec developed by the Alliance for Open Media—a consortium including Google, Netflix, Microsoft, Amazon and others — is already the preferred decoder for cloud-based applications, and is quickly becoming the standard for video compression of all types.
