PER CURIAM:

Ayyakkannu Manivannan filed a complaint pursuant to the Freedom of Information

Act (“FOIA”), 5 U.S.C. § 552, against the Department of Energy’s National Energy

Technology Laboratory (“NETL” or “agency”), alleging that the NETL failed to

adequately respond to several requests for records pursuant to the FOIA. The district court

granted summary judgment in favor of the NETL. For the reasons that follow, we vacate

the district court’s order and remand for further proceedings.

In reviewing a district court’s grant of summary judgment in favor of the government in a FOIA action, we must determine de novo whether, after taking the evidence in the light most favorable to the nonmovant, there remains no genuine issue of material fact and the government is entitled to judgment as a matter of law.

Wickwire Gavin, P.C. v. U.S. Postal Serv., 356 F.3d 588, 591 (4th Cir. 2004). Federal

agencies are required to disclose agency records unless the records may be withheld

pursuant to one of nine enumerated exemptions listed in 5 U.S.C. § 552(b). We review

factual conclusions that place a document within a FOIA exemption for clear error and

legal conclusions de novo. Empower Oversight Whistleblowers & Rsch. v. Nat’l Insts. of

Health, 122 F.4th 92, 99 (4th Cir. 2024); Wickwire Gavin, 356 F.3d at 591. “We narrowly

construe the FOIA exemptions in favor of disclosure.” Wickwire Gavin, 356 F.3d at 591.

We conclude that the district court erred in finding that the NETL met its burden to

show that it properly redacted or withheld information pursuant to statutory exemptions in

5 U.S.C. § 552(b) with regard to request Numbers 833 and 946. The agency bears the

burden of sustaining its action to withhold information under any of the FOIA exemptions.

Zaid v. Dep’t of Just., 96 F.4th 697, 704 (4th Cir. 2024) (citing 5 U.S.C. § 552(a)(4)(B));

2 USCA4 Appeal: 25-1206 Doc: 11 Filed: 07/28/2026 Pg: 3 of 3

see Malone v. U.S. Pat. & Trademark Off., 175 F.4th 262, 269 (4th Cir. 2026) (same).

Here, the district court determined that the exemption in § 552(b)(5) applied to request

Number 946 and that the exemptions in § 552(b)(5)-(7) applied to request Number 833.

But the NETL did not argue on remand that these exemptions applied to the respective

requests and, therefore, did not meet its burden.

Accordingly, we vacate the district court’s order and remand for the district court to

determine, after further briefing from the parties, whether the exemptions apply to request

Numbers 833 and 946. We dispense with oral argument because the facts and legal

contentions are adequately presented in the materials before this court and argument would

not aid the decisional process.

VACATED AND REMANDED
