CEO, Patrick Schorn commented:

"We are pleased with the performance in the third quarter of 2021, marking a significant milestone in the operational
turnaround efforts led by our teams around the world. Our 13 operating rigs provided solid EBITDA and positive cash
flows in the quarter. The cash position is further positively impacted by the sale of our integrated well services joint
ventures and streamlining our Mexico operations.

Since our last report in August, we have continued adding backlog with currently 17 rigs being contracted or
committed which will lead to three additional warm stacked rigs being activated. We see stronger customer demand
for our rigs through a higher frequency of commercial discussions and tendering in recent months. Coupled with the
increase in recent tenders for multi-year, multi-rig contracts, this leads us to expect utilization levels to improve rapidly.
Our strong operational performance, customer reach and fleet availability uniquely places Borr Drilling in a position to
benefit from this strengthening market and we remain on track to fully contract our fleet of 23 delivered rigs by 2022.

Management has continued its engagement with various creditors with the aim to address the 2023 debt maturities.
Currently we are in advanced discussions with one of the significant creditors, having arrived at a commonly
understood framework to extend commitments substantially beyond 2023. This is subject to certain conditions,
including board approval of each respective company as well as reaching acceptable concessions from other creditor
groups.

With a continued increase in the number of active rigs and an upward adjustment of the 2022 E&P capex budgets, we
are confident in our ability to further improve our financial performance. This improvement will also provide a
foundation ultimately leading to a solution for the 2023 maturities that will benefit all stakeholders."
