April 19, 2010

Exhibit 99.1

Safe Harbor Statement

This presentation includes “forward-looking statements” within the meaning of Section 27A of the
Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended, regarding,
among other things, our business strategy, our prospects and our financial position. These
statements can be identified by the use of forward-looking terminology such as “believes,”
“estimates,” “expects,” “intends,” “may,” “will,” “should,” “could,” or “anticipates” or the negative or
other variation of these similar words, or by discussions of strategy or risks and uncertainties. These
statements are based on current expectations of future events. If underlying assumptions prove
inaccurate or unknown risks or uncertainties materialize, actual results could vary materially from the
Company’s expectations and projections. Important factors that could cause actual results to differ
materially from such forward-looking statements include, without limitation, risks related to the
following:

qIncreasing competition in the communications industry; and

qA complex and uncertain regulatory environment.

A further list and description of these risks, uncertainties and other factors can be found in the
Company’s SEC filings which are available online at www.sec.gov, www.shentel.com or on request
from the Company. The Company does not undertake to update any forward-looking statements as
a result of new information or future events or developments

Use of Non-GAAP Financial Measures

Included in this presentation are certain non-GAAP financial measures that are not determined in
accordance with US generally accepted accounting principles. These financial performance measures
are not indicative of cash provided or used by operating activities and exclude the effects of certain
operating, capital and financing costs and may differ from comparable information provided by other
companies, and they should not be considered in isolation, as an alternative to, or more meaningful
than measures of financial performance determined in accordance with US generally accepted
accounting principles. These financial performance measures are commonly used in the industry and
are presented because Shentel believes they provide relevant and useful information to investors.
Shentel utilizes these financial performance measures to assess its ability to meet future capital
expenditure and working capital requirements, to incur indebtedness if necessary, return investment
to shareholders and to fund continued growth. Shentel also uses these financial performance
measures to evaluate the performance of its businesses and for budget planning purposes.
