The Government Accountability Office has refused to reopen its dismissal of a protest FCN Inc. filed against an Internal Revenue Service cloud-modernization solicitation, holding in B-424249.2 that FCN's argument about missing salient characteristics was never actually raised until it was too late.
Background
FCN Inc., a Rockville, Maryland-based IT contractor, protested IRS RFQ No. 2032H5-26-Q-0011 earlier this year. The solicitation covers an enterprise virtualization and cloud platform modernization initiative and was structured as a brand-name-or-equal buy built around a bill of materials that named Nutanix products throughout. FCN argued the RFQ was unduly restrictive of competition and functioned as a de facto sole-source award to whichever vendor could match the Nutanix specifications most closely.
GAO issued its original decision on May 13, 2026, dismissing part of FCN's case as untimely. Under GAO's bid-protest regulations, a protester generally must raise every specific ground for challenging a solicitation's terms before the deadline for submitting quotes, or within 10 days of when the basis for protest was known or should have been known. GAO found that FCN's claim about the RFQ lacking defined "salient characteristics" for the Nutanix-based requirements — a distinct legal theory from FCN's broader restrictive-competition argument — did not appear anywhere in FCN's initial protest filing. It surfaced only later, in FCN's comments on the agency report.
GAO's timeliness rule for protest grounds comes from its own bid-protest regulations at 4 C.F.R. § 21.2(a)(2), which require that any protest challenging the terms of a solicitation — including a specific legal theory about how those terms are structured — be filed before the deadline for receipt of quotes, or within 10 days of when the basis for it was known or should have been known, whichever is earlier. The rule exists to keep agencies from having to defend against a moving target of legal theories introduced piecemeal as a protest proceeds.
FCN asked GAO to reconsider that dismissal, arguing the salient-characteristics theory was implicit in its original filing and that GAO had misread the scope of its initial protest.
Key Details
GAO's June 25, 2026 reconsideration decision sided with the IRS and rejected FCN's request outright. The office reviewed FCN's initial protest document again and confirmed it contained no distinct allegation that the RFQ was ambiguous because it failed to spell out salient characteristics equivalent products would need to meet. FCN's initial filing focused on the broader claim that the RFQ's overall structure, built around a single vendor's product line, unreasonably restricted competition. The salient-characteristics argument — a narrower, technically distinct basis under GAO's brand-name-or-equal case law — first appeared in FCN's comments responding to the agency's report defending the solicitation.
GAO reaffirmed a long-standing rule in its reconsideration decision: comments filed after an agency report are not a vehicle for introducing new, independent bases of protest. A protester's comments are meant to respond to the agency's position on grounds already raised, not to expand the case with fresh legal theories that could have been raised at the outset. Because FCN could have identified and argued the salient-characteristics issue when it filed its original protest — the RFQ language it was challenging was available to FCN from the start — GAO found no basis to excuse the delay or to conclude its original timeliness ruling was erroneous.
The reconsideration decision does not disturb whatever findings GAO reached on the timely portions of FCN's original protest; it addresses only whether the earlier dismissal of the untimely portion was itself a mistake. GAO concluded it was not, closing out FCN's last avenue to challenge the RFQ's Nutanix-specific structure through this protest.
What It Means for Contractors
The decision is a pointed reminder that GAO treats each protest ground as its own discrete legal claim requiring its own timely filing. A contractor cannot preserve a narrow argument, such as a solicitation's failure to define salient characteristics for equivalent products, simply by having filed a broader protest touching on the same solicitation. Each theory needs to be spelled out, and spelled out early.
For contractors reviewing brand-name-or-equal or vendor-specific bills of materials, the practical lesson is to build out every available legal theory before the initial protest is filed, not after receiving the agency's report. Waiting to see how an agency defends its solicitation before deciding which arguments to make is a common instinct, but GAO's regulations do not allow protesters to use the comment period as a second bite at the initial-protest apple. Contractors who suspect a solicitation lacks defined salient characteristics for an "or equal" product, or is otherwise structured to favor an incumbent's brand, need to identify and plead that specific theory within the initial 10-day or pre-award window, alongside any broader restrictive-competition claims.
The ruling also signals that agencies structuring RFQs around a specific vendor's bill of materials, as the IRS did here with Nutanix, retain latitude to do so as long as protesters fail to preserve every distinct challenge to that structure in a timely manner. Contractors bidding against incumbent-favoring specifications should treat the initial protest filing as their one chance to list every angle of attack, since GAO's forgiveness for late-raised theories remains narrow even on reconsideration.
The underlying salient-characteristics requirement FCN tried to invoke stems from FAR 11.104, which requires that when an agency writes a solicitation around a brand-name product but allows equal substitutes, the purchase description must spell out the salient physical, functional, or performance characteristics an alternate product needs to meet. That rule is meant to give competitors a clear, objective standard to bid against rather than leaving "equal" undefined — which is exactly the gap FCN said the IRS's Nutanix-based RFQ left open, even though GAO never reached the merits of that argument here.
