• Close date moved later: the deadline shifted from October 16, 2026 at 3:00 PM ET (19:00 UTC) to October 20, 2026 at 9:00 AM ET (13:00 UTC).
• Size of shift: the deadline is about four days later (roughly 4 days and 14 hours later in absolute time, since the new time is also earlier in the day).
• Why it matters: applicants gain additional time to prepare and submit proposals, which can ease pressure on drafting, budget finalization, and internal approvals. Because the new cutoff falls on a Tuesday morning rather than a Friday afternoon, teams should not assume the extra time is a full four days of working time; plan to submit well before the new 9:00 AM ET cutoff. Businesses that had built schedules around the original date should update internal milestones and confirm the submission system reflects the new deadline.

One new attachment was added to this opportunity. The filename is not specified in the available metadata, so applicants should review the updated opportunity listing on SAM.gov to identify the new document and determine its relevance to their application.

The addition of a third attachment may provide supplementary guidance, technical specifications, forms, or other materials to support proposal preparation. Applicants should download and review all current attachments before submitting.
