“Our second quarter results demonstrate Stagwell is thriving in today’s AI era. Stagwell’s unique combination of software, services and engineers is being embraced by the industry leading to another record-breaking Net New Business quarter of $171 million, highlighted by recent wins with IBM, Adobe, Mondelez and Heineken,” said Mark Penn, Chairman and CEO of Stagwell. “Our organic net revenue growth continues to accelerate, led by 18% growth in our Digital Transformation segment, and 12% growth in Communications as the political cycle starts to ramp up. Strong growth, combined with proactive cost management and share repurchases, means we are raising our adjusted EPS outlook for the year today, and we expect to deliver double-digit growth in the second half, the lions’ share of which will be organic.”

Ryan Greene, Chief Financial Officer, added: “This was Stagwell’s biggest ever second quarter. As we grew our top-line, we controlled costs to expand adjusted EBITDA 15% year-over-year to $109 million. These strong results, combined with continued share repurchases, resulted in 39% growth in adjusted EPS to $0.25. We are firmly on course to deliver on our full-year outlook, including our raised adjusted EPS guidance.”

Non-GAAP Financial Measures

In addition to its reported results, Stagwell Inc. has included in this earnings release certain financial results that the Securities and Exchange Commission (SEC) defines as “non-GAAP Financial Measures.” Management believes that such non-GAAP financial measures, when read in conjunction with the Company’s reported results, can provide useful supplemental information for investors analyzing period to period comparisons of the Company’s results. Such non-GAAP financial measures include the following:

(1) Organic Net Revenue: “Organic net revenue growth” and “Organic net revenue decline” reflects the year-over-year change in the Company’s reported net revenue attributable to the Company’s management of the entities it owns. We calculate organic net revenue growth (decline) by subtracting the net impact of acquisitions (divestitures) and the impact of foreign currency exchange fluctuations from the aggregate year-over-year increase or decrease in the Company’s reported net revenue. The net impact of acquisitions (divestitures) reflects the year-over-year change in the Company’s reported net revenue attributable to the impact of all individual entities that were acquired or divested in the current and prior year. We calculate impact of an acquisition as follows: (a) for an entity acquired during the current year, we present the entity’s current period reported revenue as the impact of the acquisition in the current year; and (b) for an entity acquired in the prior year, we present an amount equal to the entity’s current year net revenue for the same period during which we didn’t own the entity in the prior year as the impact of the acquisition in the current year. We calculate impact of a divestiture as follows: (a) for a divestiture in the current year, we present the entity’s prior year net revenue for the same period during which we no longer owned it in the current year as impact of the divestiture in the current year; and (b) for a divestiture in the prior year, we present the entity’s prior year net revenue for the period during which we owned it in the prior year as impact of the divestiture in the current year. We calculate the impact of any acquisition or divestiture without adjusting for foreign currency exchange fluctuations. The impact of foreign currency exchange fluctuations reflects the year-over-year change in the Company’s reported net revenue attributable to changes in foreign currency exchange rates. We calculate the impact of foreign currency exchange fluctuations for the portion of the reporting period in which we recognized revenue from a foreign entity in both the current year and the prior year. The impact is calculated as the difference between (1) reported prior period net revenue (converted to U.S. dollars at historical foreign currency exchange rates) and (2) prior period net revenue converted to U.S. dollars at current period foreign exchange rates.

(2) Net New Business: Estimate of annualized revenue for new wins less annualized revenue for losses incurred in the period.

(3) Adjusted EBITDA: defined as Net income (loss) attributable to Stagwell Inc. common shareholders excluding non-operating income or expense to achieve operating income (loss), plus depreciation and amortization, stock-based compensation, deferred acquisition consideration adjustments, impairment and other losses, and other items. Other items primarily includes restructuring, certain system implementation, working capital administrative fees and acquisition-related expenses. Adjusted EBITDA for our reportable segments is reconciled to Operating Income (Loss), as Net Income (Loss) is not a relevant reportable segment financial metric.

(4) Adjusted Diluted EPS: is defined as (i) Net income (loss) attributable to Stagwell Inc. common shareholders, plus net income (loss) attributable to Class C shareholders, excluding the impact of amortization expense, impairment and other losses, stock-based compensation, deferred acquisition consideration adjustments, discrete tax items, and other items (as defined above), based on total consolidated amounts, then allocated to Stagwell Inc. common shareholders and Class C shareholders, based on their respective income allocation percentage using a normalized effective income tax rate divided by (ii) the diluted weighted average shares outstanding. The diluted weighted average shares outstanding is calculated as (a) the diluted weighted average number of common shares outstanding plus (b) the shares of Class C Common Stock as if converted to shares of Class A Common Stock if not included because they were anti-dilutive.

(5) Free Cash Flow: defined as consolidated net cash flow from operations less cash outflow from capital expenditures and capitalized software, excluding material nonrecurring capital purchases. Free Cash Flow Conversion is the percentage of adjusted EBITDA.

Included in this earnings release are tables reconciling reported Stagwell Inc. results to arrive at certain of these non-GAAP financial measures.
