MEMORANDUM OPINION March 3, 2026 Wilmington, Delaware

CLG CHIEF JUDGE Plaintiff Paul C. Miller has sued RxMapper, LLC (RxMapper), James Miller, Chris Grilli, and David Upjohn for violations of the federal securities laws and common law. D.I. 2. Plaintiff alleges that Defendants engaged in a scheme to defraud Plaintiff by fabricating pretextual grounds to trigger the company’s call right, manufacturing a forced sale of Plaintiff's equity units, and undervaluing those units based on a fraudulent valuation. D.I. 2 917. The Complaint has seven

causes of action: (I) violation of § 10(b) of the Securities Exchange Act of 1934 (Exchange Act) and Rule 10b-5(a) and (c), (ID) violation of § 20(a) of the Exchange Act, (III) Common Law Fraud, ([V) Common Law Negligent Misrepresentation, (V) Tortious Interference with Contractual Relations, (VI) Conversion, and (VII) Breach of Contract. Pending before me is Defendants’ motion to dismiss Counts I through VI of the Complaint pursuant to Federal Rule of Civil Procedure 12(b)(6). D.I. 17. BACKGROUND The following background is based on the factual allegations in the Complaint and in documents explicitly relied upon in the Complaint. I must accept these allegations as true and read them in the light most favorable to Plaintiff for the purposes of deciding this Rule 12(b)(6) motion. See Umland v. PLANCO Fin.

Servs., 542 F.3d 59, 64 (3d Cir. 2008); Schmidt v. Skolas, 770 F.3d 241, 249 (3d Cir. 2014). RxMapper is a “personalized medication platform and telehealth consult practice that analy[zes] the DNA sequencing results of patients and identifies which drugs patients should and should not take based on their DNA, resulting in lower costs and better healthcare outcomes.” D.I. 2 4 20. Plaintiff co-founded RxMapper with the Defendants Chris Grilli, Jim Miller, and David Upjohn (collectively, the Individual Defendants), who are the three managers of RxMapper, a limited liability company. D.I. 2 29, 34. The parties executed an Operating Agreement on or about June 25, 2018, and each received Founding Member common units, giving them an equity stake in the company: 34,500 units each (34.85% equity) for Grilli and Upjohn, and 15,000 units each (15.15% equity) for Paul and Jim Miller. D.I. 2 § 29. Plaintiff alleges that Defendants “engineered and executed a scheme to bring about an illegitimate and illegal forced sale of [Plaintiff's] Founding Member equity securities back to RxMapper at a valuation that was wrongfully manipulated to be so low as to constitute outright fraud.” D.I. 2 91. The scheme began in 2022 when the Individual Defendants gifted 16,000 incentive units to Jim Miller to expand his ownership in the company to 27%, while decreasing Plaintiff s ownership to 13%, excluding Plaintiff from the meeting approving the issuance of

the units despite his objection to the new shares. D.I. 2 {{][ 32, 34, 37, 38. Plaintiff

also alleges that the Individual Defendants amended the Operating Agreement in

June 2022 to remove his access to the Company’s data room and keep him out of

the signature block on the agreement, in effect exiting him from the inner circle of Initial Members and centralizing control of the Company into Defendants’ hands. D.I. 2 9931, 33, 39. Plaintiff describes Defendants’ scheme, excluding the initial amendment to the Operating Agreement and dilution of Plaintiff's shares, as having five steps, each with a name of its own. 2 J 2-3. First was the Blessing Lie: Defendants lied to Plaintiff in August and September 2022 about whether he could effectuate Simple Agreements for Future Equity (SAFE)—a financial instrument that defers equity issuance—involving his Founding Member units with members of his college fraternity Phi Psi. D.I. 2 9§ 2, 40. Plaintiff alleges that Defendants expressly permitted him to execute SAFE transactions with Phi Psi investors and ensured that doing so would not violate the Company’s Operating Agreement or trigger Defendants’ right of first refusal. D.I. 2 40-46. Second was the About-Face Lie: Defendants lied by “claiming the transactions that they themselves previously blessed were now being disallowed and asserting that such transactions triggered a call right under the Company’s operating agreement.” D.I. 2 93,47. Specifically, Plaintiff alleged that Chris

Grilli sent him emails in December 2022 and January 2023 stating that Plaintiff

“was not to sell interests” in RxMapper Founding Member Units and that doing so

would meet the definition of “Transfer” under the Operating Agreement and allow RxMapper to assert a right of first refusal. D.I. 2 47-48. Third was the Call Right Artifice: Defendants, realizing they missed their window to exercise their call right, hatched a plan to “fix” the error by using “a

secret second amendment of the Company’s operating agreement that precisely expanded Defendants’ purported ability to declare the triggering of the purported call right.” D.I. 2 §§ 3,51. The first amended Operating Agreement only permitted a call right within ninety days of the date of the event giving rise to the call right—a day “in September 2022” (but not identified specifically in the Complaint), when Plaintiff attempted to transfer his units. D.I. 2 99 51, 54. Accordingly, Defendants amended the Operating Agreement again in secret in January 2023 to permit exercising the call right within 90 days of “becoming aware” of the triggering Transfer. D.I. 2 J 51-56. The Company’s law firm sent an email in March 2023 that revealed this amendment, advised Plaintiff that he breached the Operating Agreement by transferring his units in RxMapper and that RxMapper could invoke its call right, and refused Plaintiffs requests for a books- and-records inspection. D.I. 2 §§ 47-50, 58-59.

Fourth was the Forced Sale Artifice: on April 5, 2023, Defendants sent a

letter to Plaintiff stating that Plaintiff breached the Operating Agreement and that

Defendants were exercising the Company’s call right to acquire all 15,000 of Plaintiff's Founding Member Units at a fair market value of $1.30 per unit. DI. 2 44 50, 60. The buyout letter also stated that Defendants had elected to reduce the purchase price of the units by 25% because of material breach of the Operating Agreement. D.I. 2 4 61. Fifth and last was the Valuation Lie: Defendants told Plaintiff that RxMapper’s value was only $150,000 while telling investors that RxMapper’s value was at least $150 million, thus “forc[ing] the sale of Plaintiff's equity securities back to the Company at this fraudulently depressed valuation.” D.I. 2 {7 3, 60-63. Plaintiff also alleges that Defendants estimated the value of RxMapper as at least $150 million many times, citing to investor decks, ongoing litigation, a grant from the University of Wisconsin-Madison, a contract with Mayo Clinic, and an agreement with Scripta Insights. D.I. 2 § 62-76. Il.
