GLOBAL NOTES AND STATEMENT OF LIMITATIONS, METHODOLOGY, AND DISCLAIMERS REGARDING THE DEBTOR’S AMENDED² MONTHLY OPERATING REPORT

On June 23, 2026 (the “Petition Date”), Sangamo Therapeutics, Inc. (the “Debtor”) commenced the above-captioned chapter 11 case by filing a voluntary petition for relief under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”) with the United States Bankruptcy Court for the District of Delaware (the “Court”). The Debtor is authorized to operate its business as a debtor-in-possession pursuant to sections 1107(a) and 1108 of the Bankruptcy Code.

General Methodology

The Debtor is filing its monthly operating report (the “MOR”) for the period from July 1, 2026 through July 31, 2026 (the “Reporting Period”) for purposes of complying with the monthly reporting requirements applicable in the Debtor’s chapter 11 case. The MOR is unaudited and has not been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and does not include all of the information and footnotes required by U.S. GAAP. The MOR is not intended to reconcile to any financial statements otherwise prepared or distributed by the Debtor. The MOR should not be relied upon by any persons for information relating to current or future financial condition, events, or performance of the Debtor or its affiliates, as the results of operations contained herein are not necessarily indicative of results which may be expected from any other period or for the full year and may not necessarily reflect the results of operations, financial position, and schedule of receipts and disbursements in the future.

¹	The Debtor and the last four digits of its taxpayer identification number are: Sangamo Therapeutics, Inc. (9556). The Debtor’s mailing address is 501 Canal Blvd., Ste A100, Richmond, CA 94804.

This amended monthly operating report amends the July monthly operating report filed at Docket No. 427 to add information regarding payments inadvertently made to ordinary course professionals, as set forth in part 5(b) of the monthly operating report form and the attached attestation titled “Part 7(b) and 7(h) Payments Without Court Approval.”

Basis for Presentation

In preparing the MOR, the Debtor relied on financial information from its books and records at the time of such preparation. The financial information contained in the MOR is derived from the Debtor’s books and records without, among other things, all adjustments or reclassification that may be necessary or typical to accord with U.S. GAAP.

This information has not been subjected to procedures that would typically be applied to financial information presented in accordance with U.S. GAAP or any other recognized financial reporting framework. If such procedures were applied, the Debtor believes that the financial information presented in the MOR could be subject to change, including material change.

Although the Debtor made efforts to ensure the accuracy and completeness of the MOR, given the complexity of the Debtor’s business, inadvertent errors or omissions may occur. Accordingly, the Debtor hereby reserves all rights to dispute the nature, validity, status, enforceability, or executory nature of any claim amount, agreement, representation, or other statement set forth in the MOR. Further, the Debtor reserves the right to amend or supplement the MOR, if necessary, but shall be under no obligation to do so.

Moreover, given, among other things, the uncertainty surrounding the valuation and ownership of certain assets and the valuation and nature of certain liabilities, to the extent the Debtor shows more assets than liabilities, it is not an admission that the Debtor was solvent as of the Petition Date or at any time prior to the Petition Date. Likewise, to the extent the Debtor shows more liabilities than assets, it is not an admission that the Debtor was insolvent at the Petition Date or any time prior to the Petition Date.

For the reasons discussed above, there can be no assurance that the financial information presented in the MOR is complete, and readers are strongly cautioned not to place undue reliance on the MOR.

Each signatory to the MOR has necessarily relied upon the efforts, statements, advice, and representations of personnel of the Debtor and the Debtor’s advisors and professionals. Each signatory has not (and could not have) personally verified the accuracy of each such statement, representation, and answer contained in the MOR.

Reporting Period

Unless otherwise noted herein, the MOR generally reflects the Debtor’s books and records for the applicable Reporting Period. Unless otherwise noted herein, no adjustments have been made for activity occurring after the close of the Reporting Period.

Accuracy

The financial information disclosed in the MOR was not prepared in accordance with federal or state securities laws or other applicable non-bankruptcy law or in lieu of complying with any periodic reporting requirements thereunder. Persons and entities trading in or otherwise purchasing, selling, or transferring the claims against or equity interests in the Debtor should evaluate the financial information in light of the purposes for which it was prepared. The Debtor and its advisors are not liable for and undertake no responsibility to indicate variations from securities laws in the MOR or for any evaluations of the Debtor, including of their financial condition, based on this financial information or any other information.

Debtor in Possession Financing

On June 25, 2026, the Court entered the Interim Order (A) Authorizing the Debtor to Obtain Postpetition Financing, (B) Granting Liens and Providing Claims with Superpriority Administrative Expense Status, (C) Modifying Automatic Stay, (D) Scheduling Final Hearing, and (E) Granting Related Relief [Docket No. 63] (the “Initial Interim DIP Order”) authorizing the Debtor to enter into a senior secured superpriority debtor-in-possession term loan facility (the “Initial DIP Facility”). Prior to the Reporting Period, the Debtor drew $10,500,000 under the Initial DIP Facility. Please refer to the motion [Docket No. 10] seeking entry of the Initial Interim DIP Order for additional information regarding the Initial DIP Facility.

On July 23, 2026, the Court entered the Interim Order (A) Authorizing the Debtor to Obtain Replacement Postpetition Financing, (B) Granting Liens and Providing Claims with Superpriority Administrative Expense Status, (C) Modifying Automatic Stay, (D) Scheduling Final Hearing, and (E) Granting Related Relief [Docket No. 176] (the “Replacement Interim DIP Order”), which among other things, authorized the Debtor to enter into a senior secured superpriority debtor-in-possession term loan facility (the “Replacement DIP Facility”) to replace the Initial DIP Facility. During the Reporting Period, the Debtor incurred $18 million in DIP Obligations (as defined in the Replacement DIP Order) under the Replacement DIP Order, $11,432,958 of which was paid by the Debtor or on the Debtor’s behalf to satisfy all outstanding obligations arising under the Initial DIP Facility, including all fees. Please refer to the motion [Docket No. 161] seeking entry of the Replacement Interim DIP Order for additional information regarding the Replacement DIP Facility.

Payment of Prepetition Claims Pursuant to First Day Orders

Pursuant to certain interim orders of the Court entered on or about June 24, 2026 and final orders of the Court entered on or about July 21, 2026 (the “First Day Orders”), the Debtor is authorized (but not directed) to pay, among other things, certain prepetition claims of employees and taxing authorities. Accordingly, these liabilities may have been or may be satisfied in accordance with such First Day Orders. To the extent any payments were made on account of prepetition claims following the Petition Date pursuant to the authority granted to the Debtor under the First Day Orders, such payments have been included in the MOR (subject to the notes and statements and limitations provided herein).

Reservation of Rights

The Debtor reserves all rights to amend or supplement the MOR in all respects, as may be necessary or appropriate. Nothing contained in the MOR shall constitute a waiver of any of the Debtor’s rights or an admission with respect to any claim against the Debtor or otherwise in connection with this chapter 11 case

Specific MOR Disclosures

Part 1: Cash Receipts and Disbursements

Pursuant to the Initial Interim DIP Order and Replacement Interim DIP Order (together the “Interim DIP Orders”), fees and expenses of estate professionals were placed into the Professional Fees Account (as defined in the Interim DIP Orders) maintained by the Debtor. The transfer of such funds to the Professional Fee Account were treated as a transfer between Debtor accounts, and, therefore, were not treated as a distribution in Part 1(c). Professional fees will be treated as a disbursement in the reporting period in which they are paid to the applicable professionals.

Similarly, pursuant to the interim and final orders approving, among other things, the Debtor’s proposed form of adequate assurance of payment to utility companies [Docket No. 56 & 142] (the “Utilities Orders”), the Debtor deposited funds into the Utility Deposit Account (as defined in the Utilities Orders) maintained by the Debtor prior to the Reporting Period. The funds in such account will be treated as disbursements only if they are ultimately paid to a third party.

Notes to Part 2: Asset and Liability Status

Unless otherwise noted, all asset and liability information included in the MOR reflects net book value, which may differ from current market value. As set forth above, this information has not been subjected to procedures that would typically be applied to financial information presented in accordance with U.S. GAAP or any other recognized financial reporting framework. If such procedures were applied, the Debtor believes that the financial information presented in the MOR could be subject to change, including material change. Asset and liability information includes intercompany claims and other assets and liabilities which may not be settled in cash.

The Debtor continues to pay postpetition invoices on account of postpetition goods provided and services rendered in the ordinary course of business.

Given the Petition Date did not occur at month end, certain prepetition and postpetition liability balances are estimated. The Debtor has sought to assign liabilities to the prepetition and postpetition periods based on the information available as of and at the time the MOR was prepared. As additional information becomes available, the allocation of liabilities between prepetition and postpetition periods may change. The Debtor reserves the right to amend the balances as it deems appropriate and any such amendments will be reflected in future MORs

The amounts listed as “Prepetition Secured Debt,” “Prepetition Priority Debt” and “Prepetition Unsecured Debt” are preliminary and are subject to ongoing review and reconciliation by the Debtor. All amounts and classifications are subject to material adjustments.

Regarding Part 2c, the Debtor does not hold inventory; therefore, no inventory valuation method is applicable.

Notes to Part 6: Postpetition Taxes

Regarding Part 6c and 6d, postpetition employer payroll taxes accrued and paid include both the employer and employee portions of payroll taxes.

Notes to Part 7: Questionnaire

Regarding Part 7a, and as mentioned above, the Debtor is authorized to pay certain prepetition claims and obligations pursuant to the First Day Orders.

Regarding Part 7g, the Debtor incurred $18 million in DIP Obligations under the Replacement DIP Facility during the Reporting Period. The DIP Obligations were paid by the Debtor or on the Debtor’s behalf to pay all outstanding obligations under the Initial DIP Facility and to fund the Debtor’s business operations and its chapter 11 case.
