AGEE, Circuit Judge:

IonQ, Inc., a public company that develops quantum computers, saw its share price close at $7.86 on May 2, 2022. Nine days later, its stock closed at $4.34. A group of aggrieved investors (the “Shareholders”) claim the drop in stock price and their attendant financial loss was caused by the Scorpion Report (the “Report”), published on May 3. The Report alleged that IonQ and its component companies had been perpetrating a widespread fraud on the market as to the value of the company. When that alleged fraud was revealed, the market reacted, leading to the stock price decline. The Shareholders then filed suit against IonQ claiming various iterations of securities fraud.

This appeal asks whether the Shareholders adequately pleaded loss causation—a necessary element to state each of their security fraud claims—by relying on the Report and IonQ’s response to it. Like the district court, we think the answer is no, so we affirm its judgment.

I.

We take the facts from the Shareholders’ proposed second amended complaint and accept the well-pleaded ones as true. Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). We also necessarily borrow from certain unchallenged papers in the record provided by IonQ that “[Share]holders failed to attach . . . to their complaint” but that are “integral to and explicitly relied on in the complaint.” Phillips v. LCI Int’l, Inc., 190 F.3d 609, 618 (4th Cir. 1999).

That said, the background explanation for this case proceeds in three parts.

A.

Two professors founded IonQ in 2015 as a startup dedicated to developing quantum computers. In October 2020, it unveiled a new product: a 32-qubit quantum computing system. 1 IonQ did not make this new system commercially available at the time but touted its revolutionary capabilities to the public. That announcement set a niche corner of technology media abuzz. One outlet, for example, recognized the potential that IonQ’s 32- qubit system could lead to the “most powerful quantum computer yet,” while also noting that “the quantum computing community” reacted to IonQ’s news with “a bit of skepticism.” J.A. 996.

dMY Technology Group, Inc. III, a technology-focused special purpose acquisition company formed in 2020, evidently took notice of IonQ’s announcement. The month after IonQ revealed its 32-qubit system, dMY approached the company to discuss a potential merger. After dMY conducted extensive due diligence into IonQ, the companies entered a merger agreement on March 7, 2021. Because dMY was a public company, its shareholders were required to vote to approve the merger before it closed. On September 28, 2021— after a campaign encouraging investors to vote to approve the corporate marriage—the

As described by the Shareholders, “[q]uantum computers are fundamentally different from ‘classical’ computers.” J.A. 987. They “use the laws of quantum mechanics . . . to represent units of information, and those units of information interact with specially designed hardware and software to solve complex problems.” Id. The use of quantum mechanics “make quantum computers much more powerful than any, even theoretical, future classical supercomputer.” J.A. 974. IonQ’s 32-qubit system would purportedly be the most powerful computing system in the world.

merger was approved by overwhelming majority. The newly merged company took the name of IonQ and began trading publicly on October 1, 2021.

B.

On the morning of May 3, 2022, Scorpion Capital LLC published the Report online as a long slide deck reporting its “finding” that IonQ was “[a] scam built on phony statements about nearly all key aspects of the technology and business.” J.A. 506. The Report, which its publisher touted as “the most in-depth due diligence to date on IonQ,” was based on certain public information and selective interviews of unnamed former IonQ employees, customers, and quantum computing experts. J.A. 508; see J.A. 507. As relevant here, the Report made four findings that led to its conclusion that IonQ was running a “quantum Ponzi scheme.” J.A. 508.

First, Scorpion Capital said its “research indicate[d] that IonQ’s purported 32-qubit ‘world’s most powerful quantum computer’ is a brazen hoax.” J.A. 508; see, e.g., J.A. 558 (“Extensive interviews with ex-executives and employees confirm our findings and lead us to conclude that the company’s claims of a 32-qubit machine are fraudulent.”).

Second, it deemed IonQ’s claims about “rapid miniaturization”—i.e., manufacturing their existing systems small enough to be commercially practical—to be “completely outrageous.” J.A. 579–80; see, e.g., J.A. 586 (quoting an anonymous ex- employee as calling IonQ’s “promotion of server-sized IonQ machines by next year” “just baloney”).

Third, it stated that IonQ misled investors about the efficacy of its computers by mischaracterizing “‘pernicious’ error rates” as indicating strong performance. J.A. 509;

see, e.g., J.A. 607 (“Virtually every ex-IonQ employee and expert we interviewed slammed the error rates shown as a joke.”).

Fourth, it concluded that “IonQ’s revenue and bookings are driven by phony related-

party deals” which “creat[ed] the illusion of commercial momentum prior to” its public listing after merging with dMY. J.A. 511; see J.A. 651 (“IonQ’s revenue is a farce: the two customers that drove 70% of its revenue in [2021] Q3 are the University of Maryland . . . and Duke. . . . The entities are so intertwined it is difficult to discern where they end and IonQ begins. . . . [IonQ is] admitting that its largest customer is itself.”).

Notwithstanding the foregoing representations, the Report’s opinions came after a long set of prefatory disclosures. The Report reveals that Scorpion Capital, the publisher, is short on IonQ stock, and therefore “stands to realize significant gains in the event that the price of its stock, bonds, options, and/or other securities decline or change.” 2 J.A. 507. Then, Scorpion Capital reveals that the nonpublic information in the Report may be
