FOR IMMEDIATE RELEASE

UScellular reports first quarter 2023 results

2023 guidance reaffirmed

CHICAGO (May 4, 2023) — United States Cellular Corporation (NYSE:USM) reported total operating revenues of $986 million for the first quarter of 2023, versus $1,010 million for the same period one year ago. Service revenues totaled $767 million, versus $787 million for the same period one year ago. Net income attributable to UScellular shareholders and related diluted earnings per share were $13 million and $0.15, respectively, for the first quarter of 2023 compared to $49 million and $0.57, respectively, in the same period one year ago.

“Postpaid subscriber trends improved year over year as we made progress toward stabilizing our customer base, but we still had net subscriber losses during the quarter and have more work to do," said Laurent Therivel, UScellular President and CEO. “We continue to make significant investments in advancing our network, while our cost optimization program is helping us improve efficiency. Finally, we continue to see momentum in two growth areas of the business - both fixed wireless and towers had another strong quarter.”

2023 Estimated Results

UScellular’s current estimates of full-year 2023 results are shown below. Such estimates represent management’s view as of May 4, 2023 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.


	2023 Estimated Results
	Previous	Current
(Dollars in millions)
Service revenues	$3,050-$3,150	Unchanged
Adjusted OIBDA1	$725-$875	Unchanged
Adjusted EBITDA1	$875-$1,025	Unchanged
Capital expenditures	$600-$700	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 2023 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.

Adjusted OIBDA (Non-GAAP)1	$725-$875	$206	$790

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, 2023, can be found on UScellular’s website at investors.uscellular.com.

1Average 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.

2Average 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.

3Handset upgrade rate calculated as total handset upgrade transactions divided by average postpaid handset connections.

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.
