Why It Matters
The company provided an early, preliminary view of its first-quarter 2026 revenue and shipment performance, which gives investors an initial indicator of quarterly results ahead of audited filings or a full earnings release.

Investors should review the attached press release (Exhibit 99.1) for the specific numbers and monitor subsequent filings for finalized results.
