OPINION ANNOUNCING THE JUDGMENT OF THE COURT
In this appeal by allowance, the Commonwealth asks us to consider whether the materiality requirement of Brady v. Maryland, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963), is satisfied where the evidence not disclosed by the Commonwealth would itself not have been admissible at trial. The Commonwealth further requests that we reconsider, based on more recent decisions by this Court and the United States Supreme Court, our holding in Commonwealth v. Green, 536 Pa. 599, 640 A.2d 1242 (1994), wherein we held that evidence that is not admissible at trial may, nevertheless, be deemed material. After careful consideration, we hold that nondisclosed favorable evidence which is inadmissible at trial may be considered material for purposes of Brady, as long as there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. Mere speculation by a defendant, however, will not be sufficient to meet this standard; rather, he must identify specific evidence or information that would have been uncovered, and explain how that evidence or information would have changed the result of the proceeding. Notwithstanding our holding, because we find that Appellee herein did not establish there was a reasonable probability that, had the evidence withheld by the Commonwealth been disclosed, there would have been a different outcome at trial, we reverse the order of the Superior Court remanding for a new trial, and reinstate Appellee’s judgment of sentence.
*651I.
The relevant facts of the instant case are as follows: At approximately 2:15 a.m. on April 29, 2005, David Thomas was walking along 6th Street in Philadelphia when two men approached him and pushed him. One of the men pulled a gun from his pocket and pointed it at Thomas’ face, telling Thomas “give us your money or we’ll blow your head off.” N.T. Trial, 10/31/06, at 46-47. Thomas gave the gunman approximately $40, and his assailants then fled. Although it was dark at the time of the incident, Thomas was able to see his assailants by the light of the streetlamps. Id. at 45-46, 68.
Approximately one hour later, after returning home, Thomas called the police to report what had happened. When the police arrived at Thomas’ home, he initially told them he would be unable to identify the men who robbed him because he was nervous and overwhelmed. Eventually, however, he gave police a description, describing the man with the gun as between 5'9" and 6' tall, with dark skin and a goatee, and wearing a puffy black coat. Thomas described the other man as light-skinned, clean-shaven, and wearing tan pants and a hockey jersey. At approximately 4:15 am., Thomas accompanied the officers to the police station, where he gave a formal statement and description.
Nearly two weeks later, on May 12, 2005, police again went to Thomas’ house and showed him a photo array of eight individuals. From the photo array, Thomas identified Michael Willis, Appellee herein, as the gunman who had robbed him. Thereafter, Willis and his accomplice, Richard Peoples, were arrested and charged with robbery1 and possession of an instrument of crime.2 On August 17, 2005, Thomas picked Willis out of a lineup, again identifying Willis as one of his attackers. Thomas also identified Willis as the gunman both at his preliminary hearing on August 18, 2005, and at trial.
On November 1, 2006, Willis was convicted by a jury of the aforementioned charges. Prior to sentencing, Willis filed a motion challenging the verdict as against the weight and sufficiency of the evidence. Willis also filed a motion for a new trial on the basis of an alleged Brady violation by the „ Commonwealth. Specifically, Willis alleged that Peoples had made a deal with the Commonwealth prior to trial, whereby he agreed to plead guilty to certain unrelated charges in exchange for the Commonwealth’s nolle pros of certain other charges, including the robbery of Thomas. Willis averred that, in the course of his discussions with police, Peoples indicated that he committed the Thomas robbery with someone other than Willis, namely, a man named Robert Richardson a/k/a Woodard (hereinafter “Woodard”). The statement was inadvertently omitted from documents produced by the Commonwealth prior to trial, and was discovered by the prosecutor in her file following trial. The statement was brought to the trial court’s attention, and the court offered to allow the victim to view another photo array containing a photo of Woodard, but Willis’ counsel refused.
Peoples was subpoenaed to testify at a hearing on Willis’ Brady claim, but was not transported from state prison to court because, according to a statement made by the prosecutor to the trial judge at the hearing, Peoples’ attorney told the prosecutor that he would advise Peoples to invoke his Fifth Amendment rights and refuse to testify regarding the robbery. Willis’ counsel did not object to the prose*652cutor’s statement, nor did she request that Peoples be brought to court to confirm on the record that he would invoke the Fifth Amendment if asked to testify about the robbery.
In his opinion for the trial court, the Honorable Glenn B. Bronson acknowledged that Peoples’ statement, which identified someone other than Willis as the person who robbed Thomas, “plainly was exculpatory and should have been provided to the defense.” Commonwealth v. Willis, CP-51-CR-1000571-2005, unpublished memorandum at 5 (Phila. Cty. filed Sept. 4, 2007). Nevertheless, the trial court concluded that Peoples’ statement was not material within the meaning of Brady because disclosure of the statement could not have affected the outcome of the case. Specifically, the trial court reasoned that Peoples’ out-of-court statement was inadmissible hearsay, and that, based on the prosecutor’s statement that Peoples’ attorney told her he would advise Peoples not to testify, Peoples’ statement would never have been introduced to the jury. In addition, the trial court noted “the evidence at the hearing established that Woodard did not resemble [Willis], thereby making it improbable that the complaining witness confused [Willis] for Woodard and made a misidentification.” Id. at 6. Accordingly, on March 16, 2007, the trial court denied Willis’ motion for a new trial based on the Commonwealth’s alleged Brady violation, and sentenced Willis to an aggregate term of 10 to 20 years incarceration.
Following the denial of his post-trial motions, Willis appealed his judgment of sentence to the Superior Court. On May 14, 2008, the Superior Court vacated Willis’ judgment of sentence and remanded for a new trial. Commonwealth v. Willis, 1024 EDA 2007, unpublished memorandum, 954 A.2d 44 (Pa.Super. filed May 14, 2008). In doing so, the Superior Court relied on this Court’s decision in Commonwealth v. Green, supra, for the proposition that Brady does not require an analysis of the admissibility of evidence before such evidence can be deemed material. Specifically, the Superior Court noted that Peoples’ statement “goes directly to the potential innocence of Willis;” that there was no proof that Peoples would have refused to testify; and that, “even if the statement were not admissible, it is not the Commonwealth’s role to determine how defense counsel shall use such evidence.” Willis, 1024 EDA 2007, at 6.
On August 15, 2008, the Commonwealth filed a petition for allowance of appeal, and, on March 18, 2009, this Court granted the Commonwealth’s petition with respect to the following issues:
(1) Whether the Superior Court erred in finding that the materiality requirement of Brady v. Maryland, 373 U.S. 83 [83 S.Ct. 1194, 10 L.Ed.2d 215] (1963), was satisfied where the omitted statement of a codefendant would not have been admissible at trial, and the defendant did not demonstrate that its production to the defense before trial would have led to the discovery of admissible evidence?
(2) Whether this Court should reconsider its holding in Commonwealth v. Green, [536 Pa. 599] 640 A.2d 1242 (Pa. 1994), in light of subsequent decisions to the contrary of this Court and the U.S. Supreme Court.
Commonwealth v. Willis, 600 Pa. 499, 968 A.2d 224 (2009) (order). In addressing these issues on appeal, we specifically directed the parties to consider the following cases: Wood v. Bartholomew, 516 U.S. 1, 116 S.Ct. 7, 133 L.Ed.2d 1 (1995); Commonwealth v. Lambert, 584 Pa. 461, 884 A.2d 848 (2005); Commonwealth v. Mitchell, 576 Pa. 258, 839 A.2d 202 (2003); Madsen v. Dormire, 137 F.3d 602 (8th Cir. *6531998); and Wright v. Hopper, 169 F.3d 695 (11th Cir.1999).
II.
We begin with a discussion of the United States Supreme Court’s seminal decision in Brady. In that case arising in Maryland, the defendant, Brady, and his companion, Boblit, were tried and convicted at separate trials of first-degree murder. Brady was tried first, and, at trial, he took the stand and admitted his participation in the crime, but claimed that Boblit did the actual killing. After Brady was convicted, sentenced, and his conviction was affirmed on appeal, Brady discovered that, despite his counsel’s pre-trial request to examine all of Boblit’s extrajudicial statements, one of those statements, in which Boblit admitted to the actual homicide, was withheld by the prosecution. Brady’s petition for post-conviction relief was dismissed by the trial court, but the Maryland Court of Appeals reversed and remanded for a retrial on the issue of punishment only. The United States Supreme Court granted certiorari, and agreed -with the Court of Appeals that the prosecutor’s nondisclosure of Boblit’s confession violated Brady’s due process rights under the Fourteenth Amendment to the United States Constitution, explaining “the suppression by the prosecution of evidence favorable to an accused upon request violates due process where the evidence is material either to guilt or to punishment, irrespective of the good faith or bad faith of the prosecution.” 373 U.S. at 87, 83 S.Ct. 1194.
More than ten years later, in United States v. Agurs, 427 U.S. 97, 96 S.Ct. 2392, 49 L.Ed.2d 342 (1976), a case arising out of the District of Columbia, the Supreme Court extended the disclosure obligations of the prosecutor, as set forth in Brady, to situations where the prosecutor is in possession of evidence favorable to the accused, but where there has been no specific request for information by defense counsel. The Agurs Court held that, although the prosecutor does not have a duty to provide the accused with “unlimited discovery of everything known by the prosecutor,” where there are circumstances in which the exculpatory evidence in the possession of the prosecutor may be of significant value to the defense, “elementary fairness requires it to be disclosed even without a specific request.” Id. at 106, 110, 96 S.Ct. 2392.3
Nearly ten years after Agurs, in United States v. Bagley, 473 U.S. 667, 105 S.Ct. 3375, 87 L.Ed.2d 481 (1985), a case originating in Washington, the Supreme Court considered whether the prosecution had a duty to disclose evidence which, though not exculpatory, could have been used by the defense to impeach prosecution witnesses. Prior to Bagley’s trial on charges that he violated federal narcotics and firearms statutes, his counsel requested that *654the prosecution disclose any inducements that were made to witnesses that were called by the government. The prosecution failed to disclose that two of its principal witnesses had been promised the possibility of a reward for the information they supplied to investigators. Following his conviction, Bagley filed requests for information pursuant to the Freedom of Information Act and the Privacy Act of 1974, and obtained copies of form contracts between the Bureau of Alcohol Tobacco and Firearms and the two principal witnesses. The form contracts, which had been signed by the witnesses, were titled “Contract for Purchase of Information and Payment of Lump Sum Therefor,” and contained a typewritten description of services4 that the witnesses were expected to provide in exchange for $300. Bagley moved to have his sentence vacated on the basis that the government’s failure to disclose the contracts, which he could have used to impeach the two witnesses, violated his due process rights under Brady.
The district court denied Bagley’s motion, but the Court of Appeals for the Ninth Circuit reversed, disagreeing with the district court’s conclusion that the failure to disclose was harmless beyond a reasonable doubt, and holding the government’s failure to disclose the requested impeachment evidence required automatic reversal. Following grant of certiorari, the Supreme Court reversed, ruling that the prosecution has an obligation to disclose impeachment evidence as well as exculpatory evidence, as this evidence is “evidence favorable to the accused” under Brady. Bagley, 473 U.S. at 676, 105 S.Ct. 3375. The Court further explained in Bag-ley that, regardless of the specificity of a defendant’s request for evidence,5 evidence is material “if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. A ‘reasonable probability’ is a probability sufficient to undermine confidence in the outcome.” Id. at 682, 105 S.Ct. 33756; see also Strickler v. Greene, 527 U.S. 263, 280, 119 S.Ct. 1936, 144 L.Ed.2d 286 (1999); Smith v. Cain, — U.S.-, 132 S.Ct. 627, 630, 181 L.Ed.2d 571 (2012).
In 1995, in Kyles v. Whitley, 514 U.S. 419, 115 S.Ct. 1555, 131 L.Ed.2d 490 (1995), a case arising in Louisiana, the Supreme Court further extended the requirements of Brady by holding that a “prosecutor has a duty to learn of any favorable evidence known to the others acting on the government’s behalf in the case, including the police.” Id. at 437, 115 S.Ct. 1555. The high Court reiterated, however, that evidence is material under Brady, and the failure to disclose it justifies setting aside a conviction, only where there exists a reasonable probability that, *655had the evidence been disclosed, the result at trial would have been different. Id. at 434, 115 S.Ct. 1555.
Approximately six months after its decision in Kyles v. Whitley, the Supreme Court issued a per curiam, decision in Wood v. Bartholomew, 516 U.S. 1, 116 S.Ct. 7, 133 L.Ed.2d 1 (1995), another case that arose out of Washington. In Wood, respondent Dwayne Earl Bartholomew robbed a laundromat, shooting and killing the attendant in the process. Bartholomew admitted that he committed the robbery and that the shots that killed the attendant came from his gun; the sole issue at trial was whether he was guilty of aggravated first-degree murder, which required proof of premeditation, or of felony murder, which required no such proof. Part of the prosecution’s evidence consisted of statements made by Bartholomew’s brother, Rodney, and Rodney’s girlfriend, Tracy Domandy, both of whom testified that they saw Rodney sitting in his car outside the laundromat on the day of the killing. Rodney testified that his brother told him that he intended to rob the laundromat and “leave no witnesses.” Id. at 3, 116 S.Ct. 7. Tracy testified that, shortly after the robbery, Bartholomew arrived at their house, claiming, “he had put two bullets in the [attendant’s] head.” Id. Bartholomew testified in his own defense, admitting that he threatened the victim with a gun, but claiming that the gun discharged accidentally. He denied telling his brother or Tracy that he intended to leave no witnesses, and claimed that Rodney had assisted in the robbery by convincing the attendant to open the laundromat’s door after it had closed for the night.
Following his conviction for aggravated first-degree murder, and after exhausting his state remedies, Bartholomew filed a habeas petition raising, inter alia, a Brady claim based on the prosecution’s failure to produce the results of pre-trial polygraph examinations of Rodney and Tracy. Specifically, when asked whether he had assisted his brother in the robbery, or whether he and his brother were, at any time, in the laundromat together, Rodney answered in the negative; the examiner, however, concluded that Rodney’s answers suggested deception. The district court denied relief; however, the Ninth Circuit reversed. While noting that polygraph examinations are inadmissible as evidence under Washington law, even for impeachment purposes, the .court concluded that the results were, nevertheless, material under Brady, in that, had Bartholomew’s counsel known of the polygraph results, “he would have had a stronger reason to pursue an investigation of Rodney’s story,” and “likely would have taken Rodney’s deposition.” Bartholomew v. Wood, 34 F.3d 870, 875 (9th Cir.1994). The court further opined that, at such deposition, Bartholomew’s counsel “could have asked Rodney about .the polygraph results and might well have succeeded in obtaining an admission that he was lying about his participation in the crime” and “would likely have uncovered a variety of conflicting statements which could have been used quite effectively in cross-examination at trial.” Id. at 875-76.
On appeal, the United States Supreme Court reversed. Citing Kyles v. Whitley, the Court stated:
[A]s we reiterated just last Term, evidence is “material” under Brady, and the failure to disclose it justifies setting aside a conviction, only where there exists a “reasonable probability” that had the evidence been disclosed the result at trial would have been different. To begin with, on the Court of Appeals’ own assumption, the polygraph results were inadmissible under state law, even for impeachment purposes, absent a stipula*656tion by the parties, and the parties do not contend otherwise. The information at issue here, then — the results of a polygraph examination of one of the witnesses — is not “evidence” at all. Disclosure of the polygraph results, then, could have had no direct effect on the outcome of trial, because respondent could have made no mention of them either during argument or while questioning witnesses. To get around this problem, the Ninth Circuit reasoned that the information, had it been disclosed to the defense, might have led respondent’s counsel to conduct additional discovery that might have led to some additional evidence that could have been utilized. Other than expressing a belief that in a deposition Rodney might have confessed to his involvement in the initial stages of the crime — a confession that itself would have been in no way inconsistent -with respondent’s guilt — the Court of Appeals did not specify what particular evidence it had in mind. Its judgment is based on mere speculation, in violation of the standards we have established.
Wood, 516 U.S. at 5-6, 116 S.Ct. 7 (citations omitted).
In interpreting the federal precedent discussed above, this Court has explained that, in order to establish a Brady violation, a defendant must show that: (1) evidence was suppressed by the state, either willfully or inadvertently; (2) the evidence was favorable to the defendant, either because it was exculpatory or because it could have been used for impeachment; and (8) the evidence was material, in that its omission resulted in prejudice to the defendant. See Commonwealth v. Lambert, 584 Pa. 461, 471, 884 A.2d 848, 854 (2005); Commonwealth v. Collins, 585 Pa. 45, 68, 888 A.2d 564, 577-78 (2005). However, “[t]he mere possibility that an item of undisclosed information might have helped the defense, or might have affected the outcome of the trial, does not establish materiality in the constitutional sense.” Commonwealth v. Chambers, 570 Pa. 3, 29, 807 A.2d 872, 887 (2002) (citation omitted and emphasis added). Rather, evidence is material “only if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome.” Id. at 29, 807 A.2d at 887-88 (quoting Bagley, 478 U.S. at 682, 105 S.Ct. 3375).
In urging this Court to reverse the Superior Court’s decision herein to award Willis a new trial based on the Commonwealth’s alleged violation of Brady, the Commonwealth first contends that Peoples’ statement does not satisfy the materiality requirement originally established by the United States Supreme Court in Brady, modified by the Supreme Court in Wood, and ultimately adopted by this Court in Commonwealth v. McGill, 574 Pa. 574, 832 A.2d 1014 (2003), because Peoples’ statement was not against his penal interest, and thus constituted inadmissible hearsay. Commonwealth’s Brief at 9 (citing Commonwealth v. Brinkley, 505 Pa. 442, 453, 480 A.2d 980, 986 (1984) (any portions of an out-of-court declarant’s statement about others’ involvement or lack of involvement in a particular crime are neither inculpatory, nor declarations against penal interest)). With respect to the Superior Court’s reliance on this Court’s decision in Green for the proposition that evidence need not be admissible in order to be considered material for Brady purposes, the Commonwealth maintains that “Green has not represented a color-able statement of the law on this point for at least fourteen years.” Commonwealth’s Brief at 11. The Commonwealth further *657avers that “[djecisions of both the United States and Pennsylvania Supreme Courts subsequent to Green have clarified that inadmissible evidence will not be deemed material under Brady, at least where there is no showing that it would have led to the discovery of admissible evidence.” Commonwealth’s Brief at 11. To the extent Green suggests that such a showing is unnecessary under Brady, the Commonwealth asks that we reconsider Green. Commonwealth’s Brief at 18.
The Commonwealth further asserts that Willis failed to demonstrate that the prosecution’s timely disclosure of Peoples’ statement would have led to the discovery of admissible evidence that would have been reasonably likely to alter the outcome of the trial. Id. at 13. Finally, the Commonwealth contends that the Superior Court’s “remaining justifications” for its decision, including, inter alia, its opinion that Peoples’ statement would have added weight to certain facts raised by the defense, and that the Commonwealth’s actions were dishonest, are irrelevant and improper under Wood. Commonwealth’s Brief at 14-17.
Willis, conversely, contends that the Superior Court’s decision to grant him a new trial based on the prosecution’s untimely disclosure of Peoples’ statement was proper under this Court’s decision in Green, irrespective of whether the statement constituted inadmissible hearsay and regardless of any failure to demonstrate that timely disclosure of the statement would have led to the discovery of admissible evidence. According to Willis, Green represents a correct statement of the law, which should remain undisturbed. Willis further argues that, notwithstanding Green, he “sustained his burden of demonstrating that the more prompt disclosure of Peoples’ statement would have led to admissible evidence that would have been reasonably likely to alter the outcome of the trial.” Appellee’s Brief at 18.
III.
A.
We first consider the Commonwealth’s argument that Green no longer represents a correct statement of the law, and, therefore, should be expressly overruled by this Court. In doing so, we also consider Chief Justice Castille’s position, as expressed in his Concurring Opinion, that Green was never a correct statement of the law.
This Court issued its unanimous decision in Green in 1994, one year prior to the United States Supreme Court’s per cu-riam decision in Wood. In that case, Samuel Lee Green was alleged to have entered the Harrisburg, Pennsylvania apartment of the victim, a police officer, through a window, and stolen the victim’s car keys. Green then drove the stolen car to Bonnie Sue Pflugler’s house, and the two then drove back to the victim’s apartment, ostensibly for the purpose of committing another burglary. Once in the apartment, the pair stole several items, including the victim’s .357-Magnum service revolver, and then either forced the victim into the trunk of his car and later shot him, or placed the victim in the trunk after shooting him twice in the head. Green and Pflugler drove to a secluded area known as the 27th Street Extension, removed the victim from the trunk, and buried his nude body under a pile of brush. They then fled, first to Virginia, where they abandoned the victim’s car; then to North Carolina, where they stole a van; and finally to Florida, where they were arrested.
Following his arrest, Green gave various statements regarding his and Pflugler’s activities on the night the victim was murdered. In each statement, Green maintained that he was not with Pflugler when *658the victim was taken from the apartment; that he saw Pflugler and the victim standing by the trunk of the victim’s car; and that once he and Pflugler stopped in the area of the 27th Street Extension, he walked away from the car and heard two shots. Green and Pflugler were tried separately. Green, who was tried first, was convicted of first-degree murder, kidnapping, and conspiracy, and thereafter was sentenced to death.7 Green filed post-trial motions wherein he argued the Commonwealth violated Brady by failing to disclose certain exculpatory evidence prior to trial, notwithstanding his pretrial request for all favorable or exculpatory statements in the Commonwealth’s possession. Specifically, Green alleged that the prosecution failed to disclose a statement made by Thomas Moser to an investigating officer, wherein Moser recalled encountering Pflugler in a bar sometime after the murder. According to Moser, Pflugler told him that “she did something really big; that she could sit big time for it; that she shot someone; and that she killed a cop.” Green, 536 Pa. at 603, 640 A.2d at 1244. Green became aware of Moser’s statement only after Moser was called to testify for the Commonwealth at Pflugler’s trial. The trial court found that Moser’s statements were neither admissible nor exculpatory, and rejected Green’s Brady claim.
On appeal of his judgment of sentence, Green argued that the trial court erred in rejecting his Brady claim, and this Court agreed, explaining:
Recently, in Commonwealth v. Moose, 529 Pa. 218, 602 A.2d 1265 (1992), this Court discussed in detail the holding in Brady and its progeny. As we noted there, materiality is determined by different standards depending upon whether trial counsel made a specific or a general request for exculpatory evidence. For instance, where the defense gives the prosecution notice of exactly what the defense desires, the test of materiality is whether the evidence might have affected the outcome of the trial. Commonwealth v. Moose, 529 Pa. at 233, 602 A.2d at 1272, quoting United States v. Agurs, 427 U.S. 97, 104, 96 S.Ct. 2392, 2398, 49 L.Ed.2d 342, 350 (1976). Where, as here, a general, as opposed to specific, request for exculpatory evidence is made, the evidence is material “if the omitted evidence creates a reasonable doubt that did not otherwise exist ...” Moose, 529 Pa. at 233, 602 A.2d at 1272, quoting Agurs, 427 U.S. at 112, 96 S.Ct. at 2402, 49 L.Ed.2d at 355. The Court in Agurs further stated that
the omission must be evaluated in the context of the entire record. If there is no reasonable doubt about guilt whether or not the additional evidence is considered, there is no justification for a new trial. On the other hand, if the verdict is already of questionable validity, additional evidence of relatively minor importance might be sufficient to create a reasonable doubt.
Agurs, 427 U.S. at 112-113, 96 S.Ct. at 2402, 49 L.Ed.2d at 355. In determining the materiality of the omitted evidence we must, therefore, consider any adverse effect that the prosecutor’s failure to disclose might have had on not only the presentation of the defense at trial, but the preparation of the defense as well. See, United States v. Bagley, 473 U.S. 667, 105 S.Ct. 3375, 87 L.Ed.2d 481 (1985). Upon application of these principles to the facts of the instant *659case, we conclude that the evidence withheld by the Commonwealth is relevant and material.
Green, 5B6 Pa. at 604-05, 640 A.2d at 1244-45 (emphasis added).
We then determined:
A review of the record thus, evinces the relevancy and materiality of the omitted evidence at the guilt phase. First, Mos-er’s statements to the police in no way implicated appellant in the murder. Instead, they implicated only Pflugler. Moreover, knowledge of Pflugler’s statement to Moser certainly would have opened another avenue of investigation for the defense that may well have led to further exculpatory evidence. Had the defense been aware of Moser’s statements, it may also have altered its trial strategy, especially in regards to appellant’s decision not to testify since Mos-er’s statements were consistent with appellant’s own statements to the police. The omitted evidence, was also clearly relevant and material to the issue of appellant’s punishment. It is beyond peradventure that the statements of Moser would have provided the defense with strong evidence of mitigation. During- the penalty phase, the Commonwealth incorporated all other evidence from [the] guilt phase and argued therefrom that the evidence showed that appellant alone shot Officer Bowser twice in the head and that appellant alone transported Officer Bowser in the trunk of his car to a secluded area and executed him. Again, the Commonwealth argued this without any direct evidence in support thereof.
Green, 536 Pa. at 606, 640 A.2d at 1245-46. We further rejected in Green the trial court’s conclusion that Moser’s statement was not material under Brady because it was inadmissible hearsay, which did not qualify under the exception of a declaration against penal interest because it was not given under reliable circumstances. Indeed, we held that Brady does not require that nondisclosed evidence be admissible before it can be deemed material, stating:
In Brady, as here, the evidence withheld by the prosecution was a statement made by the co-defendant admitting the actual homicide. Contrary to the statement at issue here, however, the undisclosed confession in Brady clearly implicated Brady as also wanting to kill the victim. Specifically, the undisclosed confession contained statements to the effect that while both Brady and his co-defendant wanted to kill the victim, they disagreed on the manner for so doing. Because Brady had admitted his participation in the murder, claiming only that he did not do the actual shooting, the Court there correctly held that the omitted evidence would not have reduced Brady’s offense below first degree murder since that evidence did not absolve the defendant of criminal liability for the murder and was, therefore, significant only as to the punishment of Brady. Thus, it is clear that the holding in Brady as to the admissibility of the evidence was based solely on the precise facts of that case and in no way mandates that the evidence first be admissible before it can be deemed “material” to the defense.
Id. at 607, 640 A.2d at 1246.8
Prior to addressing the Commonwealth’s contention that Green is no longer a cor*660rect statement of the law, we note that Chief Justice Castille, in his Concurring Opinion, suggests that Green was wrongly-decided in the first instance because it misinterpreted federal law with respect to whether materiality under Brady extends to effects on trial preparation. Concurring Opinion at 675. According to the Chief Justice, it is unclear what United States Supreme Court authority — Agwrs or Bag-ley — the Green Court relied upon for its conclusion that Brady materiality applies to trial preparation. Moreover, the Chief Justice opines that neither Agwrs, nor Bagley, support the Green Court’s conclusion in this regard.
The Chief Justice initially opines that the Green Court’s use of the term “therefore” to preface its holding that a court should consider any adverse effect nondisclosure had on the preparation and presentation of the defense at trial suggests the Green Court was relying on Agwrs in support of its holding. Concurring Opinion at 676. While there is admittedly some ambiguity in this regard, we conclude, based upon our above discussion of Agwrs, that it is more likely the Green Court’s holding was based on Bagley. Indeed, as noted by the Chief Justice, in Agwrs,' the Supreme Court rejected the argument that “the standard [for assessing Brady materiality] should focus on the impact of the undisclosed evidence on the defendant’s ability to prepare for trial, rather than the materiality of the evidence to the issue of guilt or innocence.” Concurring Opinion at 677 (citing Agurs, 427 U.S. at 112 n. 20, 96 S.Ct. 2392). We are inclined to presume the confusion highlighted by the Chief Justice in this regard was the result of an inadvertently misplaced adverb by the Green Court, and not a deliberate misrepresentation of the law.
Nevertheless, even accepting that the Green Court was relying on Bagley, Chief Justice Castille suggests that Bagley does not support Green’s holding, noting that Justice Blackmun’s opinion in Bagley was divided into three Sections; the first outlined the factual and procedural history, the second disapproved the automatic reversal rule for Brady violations in favor of a test which focused on whether the error is material in the sense the suppression of evidence undermined the confidence in the trial, and the third discussed the concept of materiality. Sections 1 and 2 were joined by Chief Justice Burger and Justices O’Connor, White and Rehnquist, thus garnering a majority. Section 3, however, was joined only by Justice O’Connor. Justice White wrote a concurrence that was joined by the Chief Justice and Justice Rehnquist, and Justices Brennan, Marshall and Stevens dissented.9 Chief Justice Castille concludes:
The Green Court’s citation to Bagley apparently intended to refer to Section III of Justice Blackmun’s opinion, without recognizing that the expression represented the view of but two Justices. In addition, Green failed to recognize that this dictum spoke to a very specific sub-class of Brady claims. And, finally, Green mischaracterized the dictum, taking a permissive qualifier — courts may consider the effect on trial preparation — and reading it as mandatory.
Concurring Opinion at 681 (emphasis original).
*661We recognize that Green’s citation to Bagley was a general, not a pinpoint, cite, and, moreover, that Green’s citation to Bagley arguably suggested that its result was dictated by the holding of a majority in Bagley. That said, we do not believe this Court’s holding in Green was inconsistent with Bagley, or that the concurring or dissenting opinions in Bagley precluded Green’s extension of Brady materiality to consideration of trial preparation by the defense. In discussing the standard for determining materiality in Section III of the opinion in Bagley, Justice Blackmun stated:
The Government suggests that a materiality standard more favorable to the defendant reasonably might be adopted in specific request cases.... The Government notes that an incomplete response to a specific request not only deprives the defense of certain evidence, but also has the effect of representing to the defense that the evidence does not exist. In reliance on this misleading representation, the defense might abandon lines of independent investigation, defenses, or trial strategies that it otherwise would have pursued....
We agree that the prosecutor’s failure to respond fully to a Brady request may impair the adversary process in this manner. And the more specifically the defense requests certain evidence, thus putting the prosecutor on notice of its value, the more reasonable it is for the defense to assume from the nondisclosure that the evidence does not exist, and to make pretrial and trial decisions on the basis of this assumption. This possibility of impairment does not necessitate a different standard of materiality, however, for under the Strickland formulation the reviewing court may consider directly any adverse effect that the prosecutor’s failure to respond might have had on the preparation or presentation of the defendant’s case. The reviewing court should assess the possibility that such effect might have occurred in light of the totality of the circumstances and with an awareness of the difficulty of reconstructing in a post-trial proceeding the course that the defense and the trial would have taken had the defense not been misled by the prosecutor’s incomplete response.
Id. at 682-83, 105 S.Ct. 3375 (emphasis added).
In his short concurrence, Justice White agreed that evidence is material only if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different, a fact that Bagley failed to establish. In addition, Justice White agreed with Justice Blackmun that the Strickland standard — which Justice Black-mun opined would allow a reviewing court to consider any adverse effect a prosecutor’s failure to disclose might have had on the preparation or presentation of the defendant’s case — was sufficiently flexible to cover all instances of prosecutorial failure to disclose evidence favorable to the accused. Thus, although Justice White saw “no reason to attempt to elaborate on the relevance to the inquiry of the specificity of the defense’s request for disclosure, either generally or with respect to this case,” 473 U.S. at 685, 105 S.Ct. 3375 (White, J., concurring in part and concurring in judgment), and thus did not join Section III, he expressed no discomfort with Justice Blackmun’s suggestion that, under Strickland, a determination of Brady materiality may include consideration of any adverse effects on trial preparation resulting from nondisclosure.
Justice Marshall, in a dissent joined by Justice Brennan, concluded that the nondisclosure of evidence in Bagley “could not *662have been harmless,” 473 U.S. at 709, 105 S.Ct. 3375 (Marshall, J. dissenting), and would have affirmed the decision of the Court of Appeals. Justice Marshall repeatedly recognized that the state’s withholding of available evidence may affect a defendant’s strategy at trial. See 473 U.S. at 702-03, 105 S.Ct. 3375 (“I would return to the original theory and promise of Brady and reassert the duty of the prosecutor to disclose all evidence in his files that might reasonably be considered favorable to the defendant’s case. No prosecutor can know prior to trial whether such evidence will be of consequence at trial; the mere fact that it might be, however, suffices to mandate disclosure.” (emphasis original)); 473 U.S. at 707, 105 S.Ct. 3375 (“Without doubt, defense counsel develops his trial strategy based on the available evidence. A missing piece of information may well preclude the attorney from pursuing a strategy that potentially would be effective. His client might consequently be convicted even though nondisclosed information might have offered an additional or alternative defense, if not pure exculpation.”). Thus, the dissenters’ position is entirely consistent with Justice Blackmun’s suggestion that a state’s failure to disclose favorable evidence may adversely affect a defendant’s trial preparation or trial strategy-
Accordingly, while one might argue that this Court failed to adequately set forth the support for our decision in Green, upon review, we do not agree that Green is inconsistent with or unsupported by the United States Supreme Court’s decision in jBagley. Indeed, the Court of Appeals for the Third Circuit has repeatedly cited Bagley for the proposition that, in determining the materiality of evidence under Brady, the effect of the nondisclosure on the defense’s trial preparation is a relevant consideration. For example, in United States v. Perdomo, 929 F.2d 967 (3rd Cir. 1991), the court stated:
The Supreme Court has explained that “implicit in the requirement of materiality is a concern that the suppressed evidence might have affected the outcome of the trial.” United States v. Agurs, [427 U.S. 97, 96 S.Ct. 2392, 49 L.Ed.2d 342 (1976) ]; accord United States v. Bagley, [473 U.S. 667, 674-75, 105 S.Ct. 3375, 87 L.Ed.2d 481 (1985) ] (plurality opinion). A defendant is entitled to a new trial where “there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. A reasonable probability is [defined as] a probability sufficient to undermine confidence in the outcome.” Bagley, [473 U.S. at 682, 105 S.Ct. 3375]. This court has recognized that the Bag-ley inquiry requires consideration of the totality of the circumstances, including possible effects of non-disclosure on the defense’s trial preparation. Gov’t of Virgin Islands v. Martinez, 780 F.2d 302, 306 (3d Cir.1985) (quoting Bagley, [473 U.S. at 683, 105 S.Ct. 3375]).
Perdomo, 929 F.2d at 971.10
More recently, in Maynard v. Government of the Virgin Islands, 392 Fed.Appx. *663105, 2010 WL 3330193 (3rd Cir. August 25, 2010), the Third Circuit, in discussing the requirements of a successful Brady challenge, stated:
[T]he Supreme Court has suggested that a defendant may predicate a Brady claim upon prosecutorial suppression that causes the defendant to “abandon lines of independent investigation, defenses, or trial strategies that [he] otherwise would have pursued,” Bagley, 473 U.S. at 683, 105 S.Ct. 3375, provided that the defendant shows that he would have discovered admissible evidence which calls the outcome of the trial into question. Id. at 684, 105 S.Ct. 3375.
Maynard, 392 Fed.Appx. at 115. Similarly, in Robinson v. Cain, 510 F.Supp.2d 399 (E.D.La.2007), the United States District Court for the Eastern District of Louisiana recognized that the Fifth Circuit has suggested that inadmissible evidence may be material under Brady if it was “material to the preparation of a petitioner’s defense.” Id. at 412 (quoting Sellers v. Estelle, 651 F.2d 1074, 1077 n. 6 (5th Cir.1981)).
Finally, with respect to the observation of the Chief Justice that, to the extent Bagley held that courts may consider the effect of nondisclosure on the defense’s preparation for trial, Green improperly read that holding, as requiring a court to consider the same, we concede this is a valid point. We cannot conclude, however, that Green’s misstatement in this regard compels a conclusion that Green “did not square with Brady and its progeny on the day it was decided.” Concurring Opinion at 681.
We now turn to the specific arguments of the Commonwealth in this case regarding the trial court’s decision to grant Willis a new trial based on the Commonwealth’s alleged violation of Brady. In support of its argument that the trial court erred in relying on this Court’s decision in Green for the proposition that evidence need not be admissible in order to be considered material for Brady purposes, the Commonwealth avers: “the United States Supreme Court [in Wood ] clarified that admissibility is indeed a prerequisite to materiality under Brady.” Commonwealth’s Brief at ll.11 We find *664this to be an overly broad interpretation of Wood. While the Supreme Court noted in Wood that the polygraph results at issue were inadmissible, and, thus, were “not ‘evidence’ at all,” 516 U.S. at 6, 116 S.Ct. 7, the Court did not expressly hold that nondisclosed information, which would have been inadmissible at trial, could not be considered material under Brady. See, e.g., Felder v. Johnson, 180 F.3d 206, 212 n. 7 (5th Cir.1999) (the Supreme Court in Wood “did not declare squarely whether inadmissible information could be material evidence under Brady”); Paradis v. Arave, 240 F.3d 1169, 1178 (9th Cir.2001) (the Supreme Court in Wood “did not categorically reject the suggestion that inadmissible evidence can be material under Brady, if it could have led to the discovery of admissible evidence”); Wright v. Hopper, 169 F.3d 695, 704 n. 1 (11th Cir.1999) (the Supreme Court in Wood “did not declare that admissibility was a precondition to materiality”); People v. Hoyos, 41 Cal.4th 872, 63 Cal.Rptr.3d 1, 162 P.3d 528, 562 n. 28 (2007) (“Wood was not based on a per se rejection of inadmissible evidence as a basis for a Brady claim.”). But see United States v. Perez, 280 F.3d 318, 349 (3rd Cir.2002) (without opining as to the reasonableness of such approach, the court noted that the district court’s determination that the suppressed evidence was not material under Brady because it would have been inadmissible at trial was supported by Supreme Court’s decision in Wood). Rather, in holding that the court of appeals improperly found that the results of the polygraph examinations, which were inadmissible at trial, were material under Brady, the Supreme Court in Wood contemplated:
To get around this problem [of inadmissibility], the Ninth Circuit reasoned that the information, had it been disclosed to the defense, might have led respondent’s counsel to conduct additional discovery that might have led to some additional evidence that could have been utilized .... [T]he Court of Appeals did not specify what particular evidence it had in mind. Its judgment is based on mere speculation, in violation of the standards we have established.
Wood, 516 U.S. at 6, 116 S.Ct. 7.
Indeed, the absence of an explicit holding by the Court in Wood that inadmissible evidence can never be considered material for Brady purposes is evidenced by the fact that, since Wood, state and federal courts have developed different approaches with regard to this issue. For example, the Fourth Circuit, in a minority approach, has held that information that is not admissible at trial is, as a matter of law, immaterial under Brady, even if it might lead to the discovery of admissible exculpatory evidence. See Hoke v. Nether-*665land, 92 F.3d 1350, 1355 (4th Cir.1996) (“We are at a loss to understand how [statements inadmissible at trial] could even possibly be considered ‘material.’”).
The remaining circuits, however, have adopted a less restrictive approach. The First, Second, Sixth, and Eleventh Circuits have determined that inadmissible evidence may be considered material under Brady, provided disclosure of the inadmissible evidence would have led to material admissible evidence. See, e.g., Ellsworth v. Warden, 333 F.3d 1, 5 (1st Cir.2003) (“given the policy underlying Brady, we think it plain that evidence itself inadmissible could be so promising a lead to strong exculpatory evidence that there could be no justification for withholding it. Wood ... implicitly assumes this is so.” (emphasis original)); United States v. Gil, 297 F.3d 93, 104 (2nd Cir.2002) (evidence that is inadmissible at trial may be material under Brady if, inter alia, it “could lead to admissible evidence”); United States v. Phillip, 948 F.2d 241, 249-50 (6th Cir. 1991) (information withheld by the prosecution, even if inadmissible at trial, is material for Brady purposes if it “would lead directly to ... evidence admissible at trial for either substantive or impeachment purposes”); and Wright v. Hopper, 169 F.3d at 703 (holding that “[ijnadmissible evidence may be material if the evidence would have led to admissible evidence”).12
Finally, the Fifth, Seventh, and Eighth Circuits have held that a Brady violation occurs whenever there is a reasonable probability that the outcome of the trial would have been different if the information had been disclosed. See, e.g., United States v. Sipe, 388 F.3d 471, 478 (5th Cir. 2004) (“The materiality of Brady material depends almost entirely on the value of the evidence relative to the other evidence mustered by the state.”); United States v. Asher, 178 F.3d 486, 496 (7th Cir.1999) (district court did not err in denying appellant’s motion for a new trial based on Brady violation where there was no reasonable probability that the disclosure of the suppressed information would have affected the outcome of the trial); Madsen v. Dormire, 137 F.3d 602, 604-05 (8th Cir. 1998) (prosecutor who failed to disclose information about the incompetency of a nontestifying forensic chemist who performed serology tests on blood-stained items seized from a rape suspect’s home did not violate Brady because evidence of the chemist’s incompetency was not “evidence,” as the information could not have been used to impeach the testimony of the victim or the investigating officer regarding blood-stained items, and, “even assuming that information about [the chemist’s] incompetency could be considered evidence, the information would not be material because ‘[t]here simply was no showing to indicate a reasonable probability that disclosure of [the information] would have changed the outcome of the trial’ ”). Under this latter approach, whether or not the nondisclosed evidence was admissible at trial, or even would have led to the discovery of admissible evidence, is not determinative. Rather, the focus appears to be on whether the disclosure of the evidence would have “put the whole case in *666such a different light as to undermine confidence in the verdict.” Asher, 178 F.3d at 496 (quoting Kyles v. Whitley, 514 U.S. at 435, 115 S.Ct. 1555).
In our view, this latter approach contemplates that the discovery, and presumably the presentation at trial, of admissible exculpatory evidence is but one basis upon which to find there was a reasonable probability that disclosure would have changed the outcome at trial. Unlike the approach taken by the First, Second, Sixth, and Eleventh circuits, however, it accounts for situations where disclosure of the inadmissible evidence may not have led to the discovery of admissible exculpatory evidence, but would have impacted a defendant’s preparation for trial or presentation of his defense to the extent that there is a reasonable probability that the outcome of the trial would have been different had the information been disclosed. Accord, Green, 536 Pa. at 605, 640 A.2d at 1245 (in determining materiality under Brady, we must “consider any adverse effect that the prosecutor’s failure to disclose might have had on not only the presentation of the defense at trial, but the preparation of the defense as well”).
The Third Circuit has not taken a definitive position on whether, and under what circumstances, nondisclosed evidence which is inadmissible at trial may form the basis of a Brady violation. However, the Third Circuit’s decision in United States v. Perez, supra, suggests, at a minimum, that inadmissibility at trial does not preclude evidence from being considered material under Brady, and, moreover, that nondis-closed inadmissible information may be considered material if there is reasonable probability that disclosure would have changed the outcome at trial. In Perez, the appellant was convicted of, inter alia, conspiracy to distribute methamphetamine. She alleged on appeal that the prosecution violated Brady by failing to timely disclose a statement by the conspiracy’s ringleader that implicated another co-conspirator and exculpated the appellant. The appellant averred that the evidence was material because it could have been used by the defense to contradict the prosecution’s theory of the case. The district court rejected the appellant’s claim on the basis that the ringleader’s testimony, even if credible, would not have made a difference in the trial because “it could not come in for substantive consideration by the jury because it was inadmissible hearsay.” 280 F.3d at 349.
On review, the Third Circuit noted that the district court’s position was “supported in cases cited by the Government,” id., including Wood v. Bartholomew. However, the court of appeals expressed no opinion on the reasonableness of such an approach. Rather, the court expressly agreed that the value of the nondisclosed statement would have been undercut by other corroborated testimony such that “there was no reasonable probability that the suppressed evidence would have changed the outcome of the original proceeding.” Id. at 350. Such language is consistent with the approach taken by the Fifth, Seventh, and Eighth Circuits— namely, that a Brady violation occurs if there is a reasonable probability that the outcome of the trial would have been different if the information had been disclosed, because disclosure of the inadmissible evidence would have led to admissible evidence.
Here, in further support of its argument that the trial court erred in relying on this Court’s holding in Green, the Commonwealth argues that this Court’s post-Green decisions evidence a clear retreat by this Court from the position we espoused in Green — namely, that, under certain circumstances, inadmissible evidence is still *667considered material for Brady purposes. Specifically, the Commonwealth cites Commonwealth v. McGill, supra, Commonwealth v. Mitchell, 576 Pa. 258, 839 A.2d 202 (2003), and Commonwealth v. Lambert, supra. In McGill, the appellant, Bernard McGill, alleged a Brady violation based on the Commonwealth’s failure to disclose a statement made by McGill’s former cellmate, who was a jailhouse informant, to detectives. In the statement, the informant, Hassan Bilal, averred that he had a conversation with McGill, wherein McGill admitted to stabbing and raping a woman, but said that he planned to “play[ ] like he is crazy” in court in an effort to establish an insanity defense.13 574 Pa. at 583, 832 A.2d at 1019. This Court rejected McGill’s argument, stating:
To establish a Brady violation, a defendant must show that: (1) the evidence was suppressed by the state, either willfully or inadvertently; (2) the evidence at issue is favorable to the defendant; and (3) the evidence was material, meaning that prejudice must have ensued. Strickler v. Greene, 527 U.S. 263, 281-282 [119 S.Ct. 1936, 144 L.Ed.2d 286].... “The mere possibility that an item of undisclosed information might have helped the defense, or might have affected the outcome of the trial, does not establish materiality in the constitutional sense.” United States v. Agurs, [supra ]. See also United States v. Bagley, [supra ] (“evidence is material only if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome.”).
In the case sub judice, the alleged Brady violation is mere conjecture. Bilal never testified at trial. The Commonwealth gave the statement of Bilal to trial counsel. McGill merely argues that Bilal testified for the Commonwealth in another case; he speculates that, had trial counsel asked the Commonwealth for documents relating to Bilal’s participation in other cases, the Commonwealth would not have provided it. McGill does not even point to any other case in which Bilal supposedly cooperated with the Commonwealth. Thus, McGill has failed to establish that there was any evidence to suppress, let alone that the Commonwealth willfully or inadvertently suppressed it. Accordingly, McGill has not demonstrated a Brady violation.
Id. at 583-84, 832 A.2d at 1019-20 (emphasis added). As the emphasized text illustrates, while we recognized in McGill that materiality requires a reasonable probability, rather than a possibility, that the outcome of the trial would have been different, our decision that McGill failed to establish a Brady violation was based on a determination that no exculpatory or impeachment evidence was suppressed, either intentionally or inadvertently. Indeed, whether inadmissible evidence could be considered material was not an issue, and thus we question the Commonwealth’s reliance on McGill in support of its position herein.
In Commonwealth v. Mitchell, the appellant, Isaac Mitchell, raised a Brady argument based on the Commonwealth’s alleged suppression of the prior criminal record of one of its primary witnesses, Montrell Washington, at the appellant’s murder trial. According to the appellant, such evidence was exculpatory because “it would have bolstered Appellant’s testimony that [Washington] had a gun on the *668night of the shooting, and because the two convictions would have served to undermine [Washington’s] credibility.” 576 Pa. at 281, 839 A.2d at 215-16. This Court rejected Mitchell’s claim, noting that there was no evidence that the Commonwealth actually suppressed Washington’s prior criminal record. Id. at 282, 839 A.2d at 216. Although we additionally noted that Mitchell failed to establish the evidence was material to his defense — because (1) there was no evidence linking the prior convictions to the current charges and (2) firearms violations are not crimen falsi they would not have been admissible to impeach Washington’s credibility — these statements were made in the context of an alternative holding, and arguably were dicta.
Finally, the Commonwealth cites this Court’s decision in Commonwealth v. Lambert. In Lambert, this Court considered several Brady claims raised by the appellant, James Lambert, who was convicted of first-degree murder and related offenses in connection with the robbery of a Philadelphia bar. Lambert, claimed, inter alia, that the Commonwealth violated Brady by failing to disclose a police activity sheet which indicated that an individual named Snyder advised the police that Snyder’s brother told Snyder that two individuals, Paul and Robin Adams, had purchased a gun and planned to rob a bar. Upon learning of the robbery and murders at issue in the case, Snyder speculated that the Adamses had committed the crimes. Lambert maintained that the police activity sheet thus proved that someone other than him committed the robbery. We rejected Lambert’s argument, stating:
Contrary to appellant’s assertion, the information contained in this document was not evidence that someone other than appellant committed the instant crimes. As the Commonwealth notes, the information contained in this document was an initial lead based on hearsay and speculation. As noted by this Court, the prosecution is not required to disclose to the defense “every fruitless lead followed by investigators of a crime.” Commonwealth v. Crews, 536 Pa. 508, 640 A.2d 395, 406 (1994). Additionally, inadmissible evidence cannot be the basis for a Brady violation. See Wood v. Bartholomew, [supra ] (reversing grant of habeas corpus relief where evidence withheld by prosecution was inadmissible; thus, disclosure not “reasonably likely” to have resulted in different outcome); Commonwealth v. Mitchell, 576 Pa. 258, 839 A.2d 202, 216 (2003) (inadmissible evidence not material under Brady). Accordingly, the Commonwealth did not violate Brady by not disclosing this document.
584 Pa. at 475, 884 A.2d at 857. While this Court first determined that the evidence was not exculpatory to the appellant, we then — as we did in Mitchell — offered the alternative reasoning that inadmissible evidence cannot be considered material under Brady, citing the Supreme Court’s decision in Wood and our holding in Mitchell.
Notwithstanding our reference to admissibility in Mitchell, and our citation to both Mitchell and Wood as part of an alternative holding in Lambert, the language of our recent decision in Commonwealth v. Ly, 602 Pa. 268, 980 A.2d 61 (2009),14 suggests our continued endorsement of the position we first espoused in Green. In Ly, the appellant, Cam Ly, alleged that the prosecution violated Brady by failing to disclose evidence primarily related to a *669witness identification of a certain individual as a participant in the crime, which conflicted with a prior identification by the same witness. Ly alleged that the Commonwealth’s failure to disclose evidence of the conflicting identifications “undermined [his] ability to develop alternative theories and defenses in the guilt phase and to present mitigation evidence relating to his reduced role [as an accomplice as opposed to the shooter] in the crime in the penalty phase.” 602 Pa. at 292, 980 A.2d at 75.
In addressing the materiality requirement of Brady, we explained:
Materiality extends to evidence affecting the credibility of witnesses, rather than merely to purely exculpatory evidence. See Giglio v. United States, [405 U.S. 150, 92 S.Ct. 763, 31 L.Ed.2d 104 (1972) ] (“When the ‘reliability of a given witness may well be determinative of guilt or innocence,’ nondisclosure of evidence affecting credibility falls within this general rule.”). Moreover, we have held that the protection of Brady extends to the defendant’s ability to investigate alternate defense theories and to formulate trial strategy. See Commonwealth v. Green, 536 Pa. 599, 640 A.2d 1242, 1245 (1994) (holding that courts must “consider any adverse effect that the prosecutor’s failure to disclose might have had on not only the presentation of the defense at trial, but the preparation of the defense as well.”). “[F]avorable evidence is material, and constitutional error results from its suppression by the government, if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different.” Kyles v. Whitley, [514 U.S. 419, 433-134, 115 S.Ct. 1555, 131 L.Ed.2d 490 (1995) ].
602 Pa. at 293-94, 980 A.2d at 76 (emphasis added).
We held that Ly satisfied his burden of demonstrating that the evidence was favorable to him because it was related to the credibility of a witness, noting the evidence “could have been used to question [the witness’] identification of Appellant as the shooter, especially given the prosecution’s attempt to bolster [the witness’] identification of Appellant with her identification of [another individual].” Id. at 297, 980 A.2d at 78.
While we ultimately concluded that Ly was not entitled to relief because he failed to demonstrate that the alleged Brady violations so undermined the truth determining process such that no reliable adjudication of guilt or innocence could have occurred,15 we stated that Brady applies not only to purely exculpatory evidence or to evidence which relates to the credibility of witnesses, but also to evidence which impacts a defendant’s ability to investigate alternate defense theories and to formu*670late trial strategy. Id. at 293-94, 980 A.2d at 76 (citing Green, 536 Pa. at 605, 640 A.2d at 1245). Additionally, we emphasized that the proper standard for determining the materiality of evidence withheld by the prosecution was the standard set forth by United States Supreme Court in Kyles v. Whitley: “favorable evidence is material, and constitutional error results from its suppression by the government, if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different.” 602 Pa. at 294, 980 A.2d at 76 (quoting Kyles, 514 U.S. at 433, 115 S.Ct. 1555).
Although we recognize that the language used in our pronouncements on the issue of whether evidence that is inadmissible at trial can be considered material evidence for purposes of Brady has been inconsistent, we nonetheless reject the Commonwealth’s contention that Green should be overruled. Indeed, we have relied on Green in this regard as recently as December 2009 in Ly. Furthermore, as discussed above, we do not agree with the Commonwealth’s contention that Green has been supplanted by the United States Supreme Court’s decision Wood. Finally, having considered the approaches taken by the United States Supreme Court and the various circuit courts, we believe Green and Ly best accommodate the primary function of the trial process — the search for truth. See Bagley, 473 U.S. at 675 n. 6, 105 S.Ct. 3375 (“By requiring the prosecutor to assist the defense in making its case, the Brady rule represents a limited departure from a pure adversary model. The Court has recognized however, that the prosecutor’s role transcends that of an adversary: he ‘is the representative not of an ordinary party to a controversy, but of a sovereignty ... whose interest ... in a criminal prosecution is not that it shall win a case, but that justice shall be done.’ ” (citations omitted)); Kyles, 514 U.S. at 439, 115 S.Ct. 1555 (noting that a prudent prosecutor will err on the side of disclosure of evidence that may be favorable to a defendant, which “is as it should be. Such disclosure will serve to justify trust in the prosecutor as ‘the representative ... of a sovereignty ... whose interest [is] that justice shall be done.’ ” (citations omitted)).
Accordingly, we hold that admissibility at trial is not a prerequisite to a determination of materiality under Brady. Rather, the touchstone of materiality is whether there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. Therefore, nondisclosed favorable evidence which is not admissible at trial may nonetheless be considered material for Brady purposes where the Commonwealth’s failure to disclose such evidence adversely affected the presentation of the defense at trial, or the defense’s preparation for trial, such that there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. See Ly. We emphasize, however, that “mere speculation” by a defendant will not be sufficient to meet this burden. See Wood, 516 U.S. at 6, 116 S.Ct. 7. Rather, in order to establish a reasonable probability that the result of the proceeding would have been different had the evidence been disclosed, a defendant necessarily must identify specific evidence or information that would have been uncovered, and explain how that evidence or information would have changed the result of the proceeding.

Notwithstanding our determination that evidence may be considered material for Brady purposes, even if the evidence is *671inadmissible at trial, we conclude that the Superior Court in the instant case erred in finding Peoples’ statement material under Brady, as Willis failed to demonstrate that, had Peoples’ statement been disclosed in a timely manner by the Commonwealth, there was a reasonable probability that the result of the proceeding would have been different.
In support of its holding that Peoples’ statement was not material for Brady purposes, Judge Bronson explained:
Here, the record establishes that disclosure of the statement could not have affected the outcome of the case. Although Peoples had pled guilty to several robberies, he did not plead to the robbery at issue in the case at bar and, therefore, retained the right to refuse to testify about that robbery under the Fifth Amendment. Peoples was subpoenaed to a hearing held by the Court to address defendant’s Brady claim, but was not brought down from state prison. At that hearing, the attorney for the Commonwealth represented that she had conferred with Peoples’ attorney and was told that he would advise Peoples not to testify at any proceedings involving the robbery here at issue. That led the Court to find that Peoples would not have been available to testify at the trial of this case. Without Peoples’ in-court testimony, his version of the events of the robbery that tended to exculpate the defendant would not have gone before the jury. His out-of-court statement was hearsay, and no exceptions to the hearsay rule were applicable.
Moreover, the evidence at the hearing established that Woodard did not resemble the defendant, thereby making it improbable that the complaining witness confused the defendant for Woodard and made a misidentifieation (N.T. 2/16/07 at 12 (defendant is 6' 1 // and Woodard is 5' 8" tall)). Where, as here, a defendant’s conviction is premised upon eyewitness testimony and a positive identification, and not merely circumstantial evidence, an undisclosed witness statement that does not undermine the eyewitness testimony is not constitutionally material.
Finally, the Court notes that in an abundance of caution, the Court ordered, following the hearing on the Brady issue, that a photo spread be shown to the complainant that included a photo of Woodard, to verify that the complainant would not change his identification if Woodard was included as a suspect. Defense counsel subsequently filed a Supplement to Motion for Extraordinary Relief stating that “counsel is now unwilling to present any further photo spreads to the victim.” Accordingly, at defendant’s request, a photo spread including Woodard was never shown to the complainant.
While the Court does not condone the carelessness that led the Commonwealth to fail to turn Peoples’ statement over to defense counsel prior to trial, there is simply no basis in the record to conclude that its failure to do so would have changed the result of the trial. Accordingly, the Commonwealth’s Brady violation does not entitle defendant to relief.
Commonwealth v. Willis, CP-51-CR-1000571-2005, at 6-7 (case citations, footnotes, and some record citations omitted).
The Superior Court, in concluding that Peoples’ statement was material for Brady purposes, and thus reversing the trial court’s determination, reasoned:
Peoples’ statement would certainly have affected the preparation of the defense, if not the course of the trial. Green, supra. In particular, it would have added weight to certain facts raised by the *672defense: that the victim stated that he would not be able to positively identify his attacker and that Willis and Woodard have similar traits. At the very minimum, had Willis’ attorney known of Peoples’ statement she could have interviewed Peoples or Woodard or put Woodard’s picture in a photo-array.
Commonwealth v. Willis, 1024 EDA 2007, at 5. The Superior Court further noted that there was “no proof that [Peoples] would have refused to testify,” and that “even if the statement were not admissible, it is not the Commonwealth’s role to determine how defense counsel shall use such evidence.... [C]ounsel still could have used it in the general preparation of the defense.” Id. at 6.
The Commonwealth challenges the Superior Court’s conclusions, asserting that disclosure of Peoples’ statement would not have affected the outcome of Willis’ trial because (1) absent Peoples’ testimony, Willis would not have been permitted to introduce Woodard’s photo and criminal history at trial, and there was no other evidence tying Woodard to the instant robbery; and (2) Willis failed to demonstrate that disclosure of Peoples’ statement would have led to additional investigation that would have resulted in admissible evidence. Commonwealth’s Brief at 12-13. Thus, the Commonwealth contends that Willis’ claim that timely disclosure of Peoples’ statement would have led to the discovery of admissible evidence, or was reasonably likely to have resulted in a different outcome at trial, is mere speculation.
Conversely, Willis argues that, had defense counsel known of the identity of Woodard prior to trial, counsel would have investigated Woodard’s background, especially his criminal history, and obtained a copy of Woodard’s photo to show to the victim. Appellee’s Brief at 40-41. Willis further maintains that the trial court erred in denying him relief on the basis that Peoples would have asserted his Fifth Amendment privilege against self-incrimination if called as a witness by the defense because the trial court simply accepted the prosecutor’s representation in this regard, without determining the validity of Peoples’ assertion. According to Willis, the Commonwealth “essentially prevented Peoples from testifying for the defendant. The prosecutor indicated that if Peoples admitted complicity in the robbery, he would be arrested for it. Such a threat is improper and interferes with the defendant’s ability to establish his innocence.” Id. at 49. Willis further asserts that trial counsel “could have sought immunity for Peoples for purposes of an evidentiary hearing.” Id. at 41.
With respect to Willis’ argument that, had Peoples’ statement been disclosed, trial counsel could have investigated Woodard’s criminal background and obtained a photo of Woodard to show to the victim, as the trial court noted, following the hearing on Willis’ Brady claim, it directed that a photo array containing a photo of Woodard be shown to the victim for the purpose of ensuring that the victim’s identification of Willis would not change if Woodard was included as a suspect, but defense counsel objected to this procedure. In his brief, Willis offers only the following explanation for counsel’s objection: “The victim identified the defendant on a number of occasions and was in his presence during court proceedings. In view of this, it would not have been fair to the defendant to allow the victim to view a photo array with the defendant’s photo in it.” Id. at 51. Having been given the opportunity to present a photo array containing Woodard’s photo to the victim and refusing that opportunity, Willis cannot now argue that he is entitled to a new trial *673because the victim was not shown a photo array containing a photo of Woodard.
With regard to Willis’ claim that the trial court erred in determining that Peoples’ statement indicating that he committed the robbery with Woodard would not have been admissible at trial without independently verifying whether Peoples would have refused to testify, the Commonwealth points out that Willis failed to offer an affidavit or certification indicating that either Peoples or Woodard was willing to testify. In response, Willis claims that his failure to obtain an affidavit or certification is not fatal to his claim, as there was no purpose to be served by attempting to obtain an affidavit, in view of the prosecutor’s representation that Peoples intended to assert his Fifth Amendment privilege against self-incrimination. We find it disingenuous for Willis to challenge the trial court’s reliance on the prosecutor’s statement that Peoples intended to assert his Fifth Amendment rights, yet rely on the prosecutor’s statement to excuse his failure to attempt to obtain a written statement from Peoples as to whether he was willing to testify.
Finally, and notwithstanding the arguments set forth above, Willis concedes that, at the hearing on his Brady claim, “trial counsel did not fully explain to the trial court the evidence that could have been obtained from the timely disclosure of Peoples’ statement,” and suggests:
If this Court believes that the record is insufficient as to prejudice sustained by the defendant resulting from the untimely disclosure of Peoples’ statement, it is requested that the matter be remanded for additional hearings to address the question of Peoples’ willingness to testify, Peoples’ assertion of this Fifth Amendment privilege, immunity for Peoples and [Woodard], and the nature and extent of evidence that trial counsel could have presented had Peoples’ statement been timely disclosed.
Id. at 41, 42.
In our view, any failure by trial counsel to adequately demonstrate at the evidentiary hearing the prejudice sustained by Willis, or the evidence which could have been presented had Peoples’ statement been timely disclosed, is more properly raised as an ineffectiveness claim on collateral review. Accordingly, we deny Willis’ request for a remand.16
IV.
For the reasons set forth above, we find that Willis has failed to demonstrate that there is a reasonable probability the outcome of his trial would have been different had Peoples’ statement been disclosed by the Commonwealth in a timely manner. The Superior Court’s conclusion that timely disclosure of Peoples’ statement would have affected the preparation of the defense or the course of the trial, such that *674there was a reasonable probability that the outcome of trial would have been different, was based on mere speculation, which is insufficient to establish materiality under Brady. Accordingly, we reverse the order of the Superior Court granting Willis a new trial, and we remand for reinstatement of Willis’ judgment of sentence.
