NEW YORK -- United Rentals, Nations-Rent, National Equipment Services and Neff Rental grossed a combined $700 million in separate high-yield bond offerings last month. In addition, Rental Service Corp. expanded its revolving credit facility by $150 million.

While the cash infusions will be used to repay higher-cost debt and fill out fleets, a good portion is expected to be earmarked for acquisitions.

"We estimate that this deal will enable United to purchase at least $200 million to $225 million in additional annual revenue next year, possibly more if it is able to continue driving down acquisition prices," Goldman Sachs, the underwriter of the $300 million United deal, stated in a research report.
