FOR IMMEDIATE RELEASE

UScellular reports firstquarter2022results

2022 guidance reaffirmed

CHICAGO (May 5, 2022) — United States Cellular Corporation (NYSE:USM) reported total operating revenues of $1,010 million for the first quarter of 2022, versus $1,023 million for the same period one year ago. Service revenues totaled $787 million, versus $771 million for the same period a year ago. Net income attributable to UScellular shareholders and related diluted earnings per share were $49 million and $0.57, respectively, for the first quarter of 2022 compared to $60 million and $0.69, respectively, in the same period one year ago.

"UScellular’s first quarter results showed growth in retail service revenue, driven by the positive impact of ARPU," said Laurent Therivel, UScellular President and CEO. "We continue to focus on our growth areas of the business, which include prepaid, business and government, and fixed wireless. Fixed wireless gross additions increased year-over-year, and momentum continues to build in our tower business, which produced double-digit revenue growth for the first quarter.

"I continue to be impressed with the hard work and dedication of our associates, and I'd like to thank all of them for their contributions this quarter."

2022Estimated Results

UScellular’s current estimates of full-year 2022 results are shown below. Such estimates represent management’s view as of May 5, 2022 and should not be assumed to be current as of any future date. UScellular undertakes no duty to update such estimates, whether as a result of new information, future events, or otherwise. There can be no assurance that final results will not differ materially from estimated results.

	2022 Estimated Results
	Previous	Current
(Dollars in millions)
Service revenues	$3,100-$3,200	Unchanged
Adjusted OIBDA1	$750-$900	Unchanged
Adjusted EBITDA1	$925-$1,075	Unchanged
Capital expenditures	$700-$800	Unchanged

The following table reconciles EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measures, Net income or Income before income taxes. In providing 2022 estimated results, UScellular has not completed the below reconciliation to Net income because it does not provide guidance for income taxes. Although potentially significant, UScellular believes that the impact of income taxes cannot be reasonably predicted; therefore, UScellular is unable to provide such guidance.

		Actual Results
	2022 Estimated Results	Three Months Ended March 31, 2022		Year Ended December 31, 2021

Adjusted OIBDA (Non-GAAP)1	$750-$900	$	243	$	869

1EBITDA, Adjusted EBITDA and Adjusted OIBDA are defined as net income adjusted for the items set forth in the reconciliation above. EBITDA, Adjusted EBITDA and Adjusted OIBDA are not measures of financial performance under Generally Accepted Accounting Principles in the United States (GAAP) and should not be considered as alternatives to Net income or Cash flows from operating activities, as indicators of cash flows or as measures of liquidity. UScellular does not intend to imply that any such items set forth in the reconciliation above are non-recurring, infrequent or unusual; such items may occur in the future. Management uses Adjusted EBITDA and Adjusted OIBDA as measurements of profitability, and therefore reconciliations to Net income are deemed appropriate. Management believes Adjusted EBITDA and Adjusted OIBDA are useful measures of UScellular’s operating results before significant recurring non-cash charges, gains and losses, and other items as presented above as they provide additional relevant and useful information to investors and other users of UScellular’s financial data in evaluating the effectiveness of its operations and underlying business trends in a manner that is consistent with management’s evaluation of business performance. Adjusted EBITDA shows adjusted earnings before interest, taxes, depreciation, amortization and accretion, and gains and losses, while Adjusted OIBDA reduces this measure further to exclude Equity in earnings of unconsolidated entities and Interest and dividend income in order to more effectively show the performance of operating activities excluding investment activities. The table above reconciles EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measure, Net income or Income before income taxes. Additional information and reconciliations related to Non-GAAP financial measures for March 31, 2022, can be found on UScellular’s website at investors.uscellular.com.

1Q3 2021 Postpaid ARPU and ARPA amounts exclude $9 million of postpaid revenue related to an out-of-period error recorded in that quarter.

2Average Revenue Per User (ARPU) - metric is calculated by dividing a revenue base by an average number of connections and by the number of months in the period. These revenue bases and connection populations are shown below:

•Postpaid ARPU consists of total postpaid service revenues and postpaid connections.

•Prepaid ARPU consists of total prepaid service revenues and prepaid connections.

3Average Revenue Per Account (ARPA) - metric is calculated by dividing total postpaid service revenues by the average number of postpaid accounts and by the number of months in the period.

4Churn rate represents the percentage of the connections that disconnect service each month. These rates represent the average monthly churn rate for each respective period.

5Market penetration is calculated by dividing the number of wireless connections at the end of the period by the total estimated population of consolidated operating markets.
