ARCBEST CORP /DE/ 8-K

What Happened
On April 28, 2026, ArcBest Corporation (Nasdaq: ARCB) announced its unaudited first quarter 2026 financial results via a press release and related materials. The company reported results under U.S. GAAP and also provided non‑GAAP measures (including EBITDA and Adjusted EBITDA) that management uses to assess core operating performance. Reconciliations of the non‑GAAP measures to comparable GAAP figures are included in the filings. Materials for the earnings conference call—press release, supplemental information and presentation slides—were furnished as Exhibits 99.1, 99.2 and 99.3 to the Form 8‑K.

Key Details

• Filing date: April 28, 2026; results are for Q1 2026 and are unaudited.
• Exhibits furnished: Press release (Ex. 99.1), supplemental information (Ex. 99.2), and earnings presentation slides (Ex. 99.3).
• Company reports under GAAP but provided non‑GAAP measures (EBITDA, Adjusted EBITDA) and reconciliations to GAAP, included in the exhibits.
• Company notes non‑GAAP metrics are used for planning and performance assessment and may not be comparable to similarly named measures from other firms.

Why It Matters
This 8‑K signals that ArcBest has released its quarterly earnings and supporting investor materials; investors should review the press release and the reconciliations to understand both GAAP results and management’s view of underlying performance (EBITDA/Adjusted EBITDA). Non‑GAAP measures can clarify trends in core operations but should be considered alongside the GAAP financial statements because calculation methods can vary across companies.
