IN THE UNITED STATES BANKRUPTCY COURT FOR THE DISTRICT OF DELAWARE In re: NANOSTRING TECHNOLOGIES, INC., et al.,1 Debtors. Chapter 11 Case No. 24-10160 (CTG) (Jointly Administered) GLOBAL NOTES TO MONTHLY OPERATING REPORT FOR NANOSTRING TECHNOLOGIES, INC. AND ITS DEBTOR AFFILIATES On February 4, 2024, NanoString Technologies, Inc. and its debtor affiliates, as debtors and debtors in possession in the above-captioned chapter 11 cases (collectively, the “Debtors”), each commenced a voluntary case (collectively, these “Chapter 11 Cases”) under chapter 11 of title 11 of the United States Code, 11 U.S.C. §§ 101–1532 in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). The following notes and statements of limitations and disclaimers should be referred to, and referenced in connection with, any review of the Debtors’ Monthly Operating Reports (collectively, the “MORs”). Introduction. The MORs are unaudited and do not purport to represent financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and are not intended to fully reconcile to the consolidated financial statements prepared by the Debtors. Information contained in the MORs has been derived from the Debtors’ books and records but does not reflect in all circumstances presentation for GAAP or SEC reporting purposes. To comply with their obligations to provide MORs during these Chapter 11 Cases, the Debtors have prepared the MORs using the best information presently available to them, which has been collected, maintained, and prepared in accordance with the Debtors’ historical accounting practices. The MORs are true and accurate to the best of the Debtors’ knowledge, information, and belief, based on currently available data. The MORs are limited in scope, cover only the period referenced on the MOR cover pages, and have been prepared solely for the purpose of complying with the monthly reporting requirements of these Chapter 11 Cases. The results of operations and financial position contained herein are not necessarily indicative of results that may be expected for any period other than the applicable reporting period, or for the full year, and may not necessarily reflect the Debtors’ future consolidated results of operations and financial position. Although the Debtors generally prepare their financial statements on a consolidated basis, the MORs have been prepared on an entity-by-entity basis (excluding most intercompany eliminations). Given the complexity of the Debtors’ business, inadvertent errors or omission 1 The Debtors in these Chapter 11 Cases, along with the last four digits of their U.S. federal tax identification numbers, to the extent applicable, are NanoString Technologies, Inc. (4687), NanoString Technologies International, Inc. (2723), NanoString Technologies Netherlands B.V., and NanoString Technologies Germany GmbH. The Debtors’ headquarters is located at 530 Fairview Avenue North, Suite 2000, Seattle, WA 98109. Case 24-10160-CTG Doc 577 Filed 05/22/24 Page 1 of 19

2 may occur. Accordingly, the Debtors hereby reserve all of their rights to dispute the nature, validity, status, enforceability, or executory natures of any claim amount, agreement, representation, or other statement set forth in the MORs. Further, the Debtors reserve the right to amend or supplement the MORs, if necessary, but shall be under no obligation to do so. 1. Currency. Unless otherwise indicated, all amounts listed in the MORs are reflected in U.S. dollars. 2. Consolidated Entity Accounts Payable and Disbursement Systems. Cash is received and disbursed by the Debtors as described in the Debtors’ Motion for Interim and Final Orders (I) Authorizing the Debtors to (A) Continue to Maintain Their Cash Management System, (B) Honor Certain Prepetition Obligations Related Thereto, and (C) Continue to Perform Intercompany Transactions; (II) Waiving Certain Operating Guidelines; (III) Suspending Time to Comply with Section 345(b) of the Bankruptcy Code and (IV) Granting Related Relief (Docket No. 10) and the Debtors’ receipt and disbursement of cash is consistent with the Debtors’ historical cash management practices. Due to the consolidated cash management reporting system, certain cash payments may be paid out of a legal entity that is different than the legal entity at which the expenses were incurred. Disbursements attributed to each entity represent the entity on behalf of which payments were made. 3. Supporting Documentation. Statement of Cash Receipts and Disbursements. Based on guidance received from the Office of the United States Trustee for the District of Delaware in connection with the completion of UST Form 11-MOR, Part 1, Cash Receipts and Disbursements, reported cash receipts and disbursements should exclude intercompany, debtor-to-debtor transactions, and escrow account fundings. As a result, for those debtors with net intercompany cash outflows or inflows during the reporting period, the ending cash balances reported on Form 11-MOR Part 1 may not match the ending cash balances per the Debtors’ bank statements or the Debtors’ books and records. Balance Sheet. Liabilities Subject to Compromise (“LSTC”) represent the Debtors’ estimate of prepetition claims to be resolved in connection with the chapter 11 cases. As a result of the chapter 11 filings, the payment of prepetition liabilities is subject to compromise or other treatment under a plan of reorganization. The determination of how such liabilities will ultimately be settled or treated cannot be made until the Court approves a chapter 11 plan of reorganization. Accordingly, the ultimate amount of such liabilities is not determinable at this time. Prepetition liabilities that are subject to compromise are preliminary and may be subject to, among other things, future adjustments depending on Court actions, further developments with respect to disputed claims, determinations of the secured status of certain claims, the values of any collateral securing such claims, rejection of executory contracts, continued reconciliation, or other events. 4. Part 5 Questionnaire. The Debtors inadvertently made a payment to Bird & Bird LLP (“Bird & Bird”) during the reporting period (but prior to Bird & Bird’s retention in these Chapter 11 Cases), which has been listed in Part 7(h). Bird & Bird has agreed to refund such payment to the Debtors, which refund is currently in process. Case 24-10160-CTG Doc 577 Filed 05/22/24 Page 2 of 19

3 5. Part 7 Questionnaire. Pursuant to certain orders of the Bankruptcy Court entered in the Debtors’ chapter 11 cases, the Debtors were authorized (but not directed) to pay, among other things, certain prepetition claims of their employees, taxing authorities, vendors, customers, and certain other prepetition creditors. All postpetition borrowings since the inception of the case, other than trade credit, are borrowings made under the Debtors’ postpetition financing facility.
