Twist Bioscience Securities Settlement: Who Can File a Claim

The settlement covers people and entities that were damaged after buying or otherwise acquiring Twist common stock either in the December 2020 Offering under the 2020 Registration Statement or during December 20, 2018 through November 15, 2022, inclusive.

• The notice excludes the defendants; their affiliates and subsidiaries; current and former Twist officers and directors and their immediate families; the defendants’ liability insurers; entities controlled by a defendant; Twist employee retirement and benefit plans; and certain related representatives, heirs, estates, agents, successors, and assigns. People or entities with a timely valid exclusion request are also excluded.
• Receiving the notice does not itself establish membership or payment eligibility.

You must submit a timely, valid Proof of Claim to be eligible for payment. Complete and sign the form, and include the documents the form requests.

• Submit online or obtain a paper form from the official site or Simpluris at (833) 386-6546. The official claim page, checked September 10, 2026, requires online submission or a mail postmark by November 17, 2026: https://www.twistsecuritiessettlement.com/form/securities-claim. The original PDF below has a blank deadline; the updated official notice supplies this date.
• Mail only to Twist Securities Settlement, c/o Claims Administrator, P.O. Box 25199, Santa Ana, CA 92799. Do not send a claim to the Court.

The settlement fund is $17.05 million in cash, plus interest. Court-approved attorneys’ fees and expenses, any award to the lead plaintiff, notice and claims-administration costs, and taxes are paid before the remaining Net Settlement Fund is distributed.

• A valid claimant’s payment is based on that claimant’s recognized claim compared with all other authorized claimants’ recognized claims. It is not a fixed amount.
• The notice estimates an average recovery of about $0.31 per eligible share before court-approved fees, expenses, and costs, assuming claims are submitted for all shares estimated to be eligible. That is only an estimate.
• No payment will be made if the calculated distribution is less than $10.

The Plan of Allocation calculates a recognized loss for each qualifying purchase. For a purchase that qualifies under both parts of the plan, the claimant receives the greater applicable recognized-loss amount, not the two amounts added together.

• Offering shares have separate rules. The plan describes purchases directly from an underwriter at the $110 offering price and requires supporting records. Its footnotes presume documented purchases at that price around December 2, 2020 were offering purchases; the calculation caps higher prices at $110 and uses a lower price when applicable. Ask the administrator how these provisions apply to your records.
• The other calculation considers when shares were bought and sold and the price change around the November 15, 2022 disclosure. Read Appendix A for the full formulas rather than treating a recognized loss as the amount you will receive.
• The updated official notice, checked September 10, 2026, fills the old notice's mailing-date placeholder with August 7, 2026 in the offering-share calculations: https://cw.simpluris.com/docs/public/downloads/TPC2/LONG_FORM_NOTICE. The retained original PDF remains available below.

For ordinary Exchange Act calculations, shares sold before November 15, 2022 have a recognized loss amount of $0. The plan uses separate rules for qualifying December 2020 Offering shares.

• The plan matches multiple purchases and sales using first in, first out (FIFO): earlier shares are treated as sold before later shares.
• A transaction used to cover a short sale, and an uncovered short sale, has a recognized loss amount of zero.
• For stock obtained or sold through an option exercise, the plan uses the option exercise date and exercise price. Gifts, inheritances, and transfers by operation of law generally do not count as purchases or sales, subject to limited conditions stated in the plan.

Excluding yourself means leaving the settlement. You would not receive a payment from this settlement, but you would not be bound by the settlement’s release of claims.

• Submit an exclusion request online or by mail to the Claims Administrator. Telephone and email requests are not accepted.
• The request must identify the case; give the requester’s name, address, and telephone number; state that the requester wants to be excluded; include records of Twist stock purchases and sales during the Class Period; and be signed. An authorized representative must include proof of authority. See notice Question 14 for every requirement, including dates, prices and share counts. Mail to Twist Securities Settlement, EXCLUSIONS, c/o Simpluris, Inc., P.O. Box 25199, Santa Ana, CA 92799.
• The administrator must receive your request by October 7, 2026, according to official FAQ 14 checked September 10, 2026 (https://www.twistsecuritiessettlement.com/faq/). The original PDF leaves the date blank. Do not also send a claim or objection: the notice says those will be disregarded if you request exclusion.

If you remain in the settlement class, you may object to the settlement, Plan of Allocation, requested attorneys’ fees and expenses, or a requested award to the lead plaintiff. You cannot object if you exclude yourself.

• Send the objection only to the Court. It must identify the objector, provide contact information and documents showing class membership and relevant transaction details, and explain the reasons for the objection. Include whether your objection concerns only you, a subgroup or the whole class. Follow all requirements in notice Question 19; it also explains possible court exceptions for good cause.
• Official FAQ 19, checked September 10, 2026, sets October 7, 2026 as the Court's receipt deadline (https://www.twistsecuritiessettlement.com/faq/); a postmark alone is insufficient. The original PDF leaves the date blank. Send it to the Clerk, U.S. District Court, Northern District of California, San Jose Division, Robert F. Peckham Federal Building & United States Courthouse, 280 South 1st Street, Room 2112, San Jose, CA 95113.
• To ask to speak at the Final Approval Hearing, state an intention to appear in a timely objection.

The notice identifies the hearing location as Courtroom 7, on the fourth floor of the Robert F. Peckham Federal Building & United States Courthouse, 280 South 1st Street, San Jose, California 95113.

• Official FAQ 21 schedules the hearing for November 18, 2026 at 10 a.m. (https://www.twistsecuritiessettlement.com/faq/, checked September 10, 2026). No time zone is stated. The original PDF leaves the date and time blank. Check the official site before attending; the Court may change the schedule or allow remote participation.
• You do not need to attend to remain in the class or to show approval.

If you stay in the settlement class and do nothing, you will not receive a payment because a Proof of Claim is required.

• Unless you validly exclude yourself, you will be bound by the settlement and give up the released claims against the defendants and their related parties. The release applies whether or not you file a claim.
• Payment can be made only if the Court approves the settlement, claims are processed, and any appeals are resolved. The notice does not provide a payment date.

The official claim instructions checked September 10, 2026 require records of every requested holding and trade, including profitable trades, ordered by trade date. Supply broker confirmations, statements or equivalent proof; missing information may cause rejection. The administrator may ask for more.

• File through the actual owner or an authorized representative with proof of authority. Keep different legal owners separate and combine the same owner's accounts. Non-U.S. persons must include the appropriate W-8 form. Large electronic filings also need a signed claim and administrator acceptance. See the complete instructions: https://www.twistsecuritiessettlement.com/form/securities-claim.

There is a difference affecting the stock-loss calculation. The original notice's Appendix A paragraph 10 includes purchases through November 15, 2022. The updated official notice's paragraph 10 ends at November 14, although its class definition and Appendix A paragraph 2 still include November 15.

• Checked September 10, 2026: updated notice at https://cw.simpluris.com/docs/public/downloads/TPC2/LONG_FORM_NOTICE; original notice below, physical page 28. If you bought on November 15, ask Simpluris at (833) 386-6546 or [email protected] how this affects your claim. We have not treated either calculation date as a final decision on your eligibility.
