United States District Court, Western District of Washington

Opinion

THE HONORABLE MICHELLE L. PETERSON

WESTERN DISTRICT OF WASHINGTON OSTERHAUS PHARMACY, INC., CAMMACK’S PHARMACIES INC., DBA NO. 2:24-CV-00039-RAJ-MLP JIM’S PHARMACY AND HOME HEALTH, HARBOR DRUG CO., INC., VALU DRUGS STIPULATED MOTION AND INC., SMITH’S PHARMACY II, INC., DBA [PROPOSED] ORDER TO MODIFY SMITH’S PHARMACY, REDNER’S THE SCHEDULING ORDER TO MARKETS, INC., and OLD BALTIMORE EXTEND CASE SCHEDULING PIKE APOTHECARY, INC., T/A DEADLINES PHARMACY, on behalf of themselves and all NOTED FOR CONSIDERATION: others similarly situated, MARCH 4, 2026 Plaintiffs, v. EXPRESS SCRIPTS, INC.,

Defendant.

Plaintiffs Osterhaus Pharmacy, Inc., Cammack’s Pharmacies Inc., d/b/a Jim’s Pharmacy and Home Health, Harbor Drug Co., Inc., Valu Drugs Inc., Smith’s Pharmacy II., Inc. d/b/a Smith’s Pharmacy, Redner’s Markets, Inc., and Old Baltimore Pike Apothecary, Inc., t/a Southern Chester County Pharmacy (“Plaintiffs”); and Defendant Express Scripts, Inc., (“Express Scripts” or “Defendant”) (collectively, the “Parties”), by their counsel, submit this Stipulated Motion to Modify the Scheduling Order (ECF No. 93), pursuant to Fed. R. Civ. P. 6(b) and Local Civ. R. 7(j) & 10(g). The Court may extend discovery deadlines upon a showing of good cause by the moving parties. See, e.g., Weyerhaeuser Co. v. Accurate Recycling Corp., 244 F.R.D. 648, 649 (W.D. Wash. 2007) (extending discovery deadlines for good cause). Good cause exists to extend all remaining case scheduling deadlines in this case. The Parties are actively engaged in document discovery and third-party discovery. The Parties continued to negotiate over document productions following Plaintiffs’ Motion to Compel Use of Plaintiffs’ Proposed Search Terms for Electronically Stored Information (ECF No. 126) and Plaintiffs’ Motion to Compel Structured Data (ECF No. 108). The Parties reached a compromise to avoid the need for Court intervention, and Plaintiffs withdrew the motions under Local Civ. R. 7(l) (ECF No. 142). As part of that compromise, the Parties agreed that Defendant would complete its production of additional documents by June 26, 2026, approximately five weeks before the currently ordered close of fact discovery. To ensure the Parties can efficiently conduct deposition discovery on a full documentary record, the Parties agree that it will not be possible to complete discovery and meet subsequent Court deadlines as currently scheduled. Accordingly, the Parties stipulate to and respectfully request that the Court extend all remaining deadlines in the Case Scheduling Order (ECF No. 93) by 90 days, as follows: EVENT CURRENT DATE PROPOSED DATE Fact discovery deadline August 6, 2026 November 4, 2026 Deadline for Parties to serve expert September 17, 2026 December 16, 2026 reports on all issues on which they have the burden of proof (class and merits) Deadline for opposition expert reports October 29, 2026 January 27, 2027 Deadline for reply/rebuttal expert reports December 3, 2026 March 3, 2027 Deadline to complete expert depositions January 7, 2027 April 7, 2027 Deadline to file class certification and January 21, 2027 April 21, 2027 Daubert motions

Deadline to file opposition to class February 18, 2027 May 19, 2027 certification and Daubert motions Deadline to file replies in support of March 11, 2027 June 9, 2027 Daubert motions and class certification The foregoing is hereby stipulated by and between all counsel as of this 4th day of March, 2026.
