MARTEN TRANSPORT LTD 8-K

What Happened

• Marten Transport Ltd. announced its financial results for the quarter and year ended December 31, 2025 via a press release dated January 27, 2026 (filed as Exhibit 99.1 to the 8‑K). The company also furnished an investor presentation (Exhibit 99.2) that may be used in investor conferences and other forums during 2026.
• The press release includes non‑GAAP measures — specifically operating revenue net of fuel surcharge revenue and operating expenses as a percentage of operating revenue (both net of fuel surcharge) — and, pursuant to Regulation G, Marten provided reconciliations of those non‑GAAP measures to the most directly comparable GAAP measures.

Key Details

• Filing date: January 27, 2026; Reporting period: quarter and fiscal year ended December 31, 2025.
• Exhibits included: 99.1 (press release with results and non‑GAAP metrics) and 99.2 (investor presentation slides).
• Non‑GAAP measures disclosed relate to revenue and expense metrics excluding fuel surcharge; reconciliations to GAAP measures are provided in Exhibit 99.1.
• The investor slides (Exhibit 99.2) are furnished under Regulation FD and may be disclosed, in whole or in part, in presentations during 2026.

Why It Matters

• Investors should review the press release and the provided reconciliations to understand both the GAAP results and the company’s non‑GAAP view of operations (which exclude fuel surcharge effects). Those non‑GAAP metrics can change how revenue and margins look compared with raw GAAP figures.
• The furnished investor slides show the material the company plans to present to analysts and investors in 2026, so they can provide additional context on strategy and performance trends beyond the press release. The filing notes these materials are furnished (not “filed”) and are not automatically covered by Section 18 liability.
