Second Quarter 2024 Highlights

• The Company renewed one of its primary monetization relationships with Google.

• CouponFollow.com experienced a 36% year-over-year increase in organic visitors to its site, and its savings-focused browser extensions surpassed 15 million monthly active users.

• Startpage launched its Private Browser app and has seen over 50,000 downloads with significantly positive user feedback, including over 2,000 five-star ratings to date across the iOS and Android app stores.

• MapQuest saw 10% year-over-year growth in organic visits to its site in the second quarter as a result of the Company’s investments in new content, faster page load speed and improved data quality. MapQuest also launched a custom "Mini Takes the States" mobile navigation application in partnership with BMW in conjunction with its bi-annual "Mini Takes the States" road trip rally event.

Third Quarter 2024 Guidance

The Company expects for the third quarter of 2024:

• Revenue between $86 million and $88 million.

• Gross Profit between $23 million and $25 million.

• Adjusted Gross Profit between $36 million and $38 million.

• Adjusted EBITDA between $8 million and $10 million.

In reliance on the unreasonable efforts exception for forward-looking information provided under Regulation S-K, the Company is not reasonably able to provide a quantitative reconciliation of Adjusted EBITDA to net loss, the most directly comparable GAAP financial measures without unreasonable effort due to uncertainties regarding purchase accounting, stock-based compensation, taxes and other potential adjustments. The difference between Gross Profit and Adjusted Gross Profit is primarily depreciation and amortization related to the cost of revenues, which are estimated to be approximately $13 million. The variability of these items could have an unpredictable, and potentially significant, impact on the Company’s future GAAP financial results. For the third quarter of 2024, the Company expects interest expense in the range of $8.0 million to $8.5 million, depreciation and amortization expense in the range of $20.5 million to $21.0 million, and acquisition and restructuring costs to be in the range of $2.0 million to $2.5 million.

The Company’s achievement of the anticipated results is subject to risks and uncertainties, including those disclosed in its filings with the U.S. Securities and Exchange Commission. The outlook does not take into account the impact of any unanticipated developments in the business or changes in the operating environment.

Non-GAAP Measures: Adjusted Gross Profit and Adjusted EBITDA

Adjusted Gross Profit and Adjusted EBITDA are non-GAAP financial measures and represent key metrics used by System1’s management and board of directors to measure the operational strength and performance of its business, to establish budgets, and to develop operational goals for managing its business. Adjusted Gross Profit (Loss) is defined as gross profit plus depreciation and amortization related to cost of revenues. Adjusted EBITDA is defined as net income (loss) before interest expense, income taxes, depreciation and amortization expense, stock-based compensation expenses, deferred compensation, management fees, minority interest expense, restructuring charges, impairment and certain discrete items impacting a particular segment’s results in a particular period.

System1 believes Adjusted Gross Profit and Adjusted EBITDA are relevant and useful metrics for investors because it allows investors to view performance in a manner similar to the method used by management. There are limitations on the use of Adjusted Gross Profit and Adjusted EBITDA and it may not be comparable to similarly titled measures of other companies. Other companies, including companies in System1’s industry, may calculate non-GAAP financial measures differently than System1 does, limiting the usefulness of those measures for comparative purposes.

Adjusted Gross Profit should not be considered a substitute for revenue or gross profit. Adjusted EBITDA should not be considered a substitute for income (loss) from operations, net income (loss), or net income (loss) attributable to System1 on a consolidated basis that System1 reports in accordance with GAAP. Although System1 uses Adjusted Gross Profit and Adjusted EBITDA as financial measures to assess the performance of its business, such use is limited because it does not include certain costs necessary to operate System1’s business. System1’s presentation of Adjusted Gross Profit and Adjusted EBITDA should not be construed as indications that its future results will be unaffected by unusual or nonrecurring items.
