American Public Education Reports First Quarter 2026 Financial Results and Raises 2026 Full-Year Guidance

CHARLES TOWN, W.V. – May 11, 2026 -- American Public Education, Inc. (the “Company”) (Nasdaq: APEI), a company that transforms lives, advances careers and improves communities by providing online and campus-based postsecondary education to approximately 109,000 students, has reported financial and operational results for the first quarter ended March 31, 2026.

“In the first quarter, we delivered strong results across our key financial metrics. We also took a significant step forward in the institutional combination when we received Higher Learning Commission approval on April 28 to consolidate our APUS, Rasmussen and Hondros College of Nursing programs, locations and operations into a single accredited institution. We remain on pace to complete our planned institutional combination at the start of the third quarter," said Angela Selden, President and Chief Executive Officer of APEI.

Selden concluded, “Q1 2026 is the first quarter of a four-year strategic plan, and the strength of our results gives us the confidence to raise our full-year 2026 guidance on both revenue and adjusted EBITDA. We believe the foundation is built, the strategy is working, and we are just getting started.”

Non-GAAP Financial Measures

This press release contains the non-GAAP financial measures of EBITDA (earnings before interest, taxes, depreciation, and amortization), adjusted EBITDA (EBITDA less non-cash expenses such as stock compensation and non-recurring expenses), adjusted EBITDA margin, segment EBITDA, and segment EBITDA margin. APEI believes that the use of these measures is useful because they allow investors to better evaluate APEI's operating profit and cash generation capabilities.

For the three months ended March 31, 2026, and 2025, adjusted EBITDA excludes stock compensation, loss on disposals of long-lived assets, loss on sale of subsidiary, transition services, severance expense, other professional fees, and loss on leases.

These non-GAAP measures should not be considered in isolation or as an alternative to measures determined in accordance with generally accepted accounting principles in the United States (GAAP). The principal limitation of our non-GAAP measures is that they exclude expenses that are required by GAAP to be recorded. In addition, non-GAAP measures are subject to inherent limitations as they reflect the exercise of judgment by management about which expenses are excluded.

APEI is presenting EBITDA and adjusted EBITDA in connection with its GAAP results and urges investors to review the reconciliation of EBITDA and adjusted EBITDA to the comparable GAAP financial measures that are included in the tables following this press release (under the captions "GAAP Net Income to Adjusted EBITDA" "GAAP Outlook Net Income to Outlook Adjusted EBITDA" and “Education Unit Profile – Segment Summary”) and not to rely on any single financial measure to evaluate its business.
