Will Greg Abel's Form 3 or DEF 14A filing reveal BRK holdings exceeding $50M in value by mid-2026?

The Form 3 absence at 60 days into Abel's CEO tenure is a meaningful negative signal. Section 16 officers must file Form 3 within 10 days of becoming subject to Section 16 -- if Abel had pre-existing BRK holdings above any threshold, his Form 3 should have appeared by January 11, 2026. Its continued absence through March 2 strongly suggests either (a) Abel held no BRK shares when he became CEO on January 1, or (b) his pre-existing holdings were minimal and his attorneys have not yet prompted a filing. Either interpretation reduces the likelihood of >$50M in holdings. However, the DEF 14A proxy is almost certain to be filed before July 15, 2026, and Abel's $870M BHE liquidity event leaves open the possibility he acquired shares through mechanisms not yet captured in EDGAR. The CEO compensation structure remains unknown -- equity grants are possible. On balance, the Form 3 absence at 60 days shifts the probability modestly downward from the prior 0.36.

The most informative update in the FY2025 10-K is what is absent: no Form 3 filing for Abel, no Form 4 purchase transactions, and no compensation disclosure. For Abel to resolve YES, he would need >$50M in BRK holdings revealed by proxy or Form 3. At ~$520/share for BRK.B, that requires approximately 96,000 B-equivalent shares. The traditional Berkshire CEO compensation has been $100K cash salary with zero equity -- if Abel negotiated an equity package, it has not been disclosed. The absence of Form 4 activity in his 60 days as CEO suggests no open-market purchases. Pre-existing holdings remain theoretically possible (he was on the board before becoming CEO), but the Form 3 absence suggests they were either zero or not yet triggering a filing obligation. The July 15 resolution window and expected proxy filing create a high probability that information will be available -- but the balance of evidence leans against the >$50M threshold being met.

I weight three factors. First, the Form 3 timing argument cuts both ways: Abel was already a Berkshire director before January 1, 2026, so he may have already had Section 16 obligations and his Form 3 as director (not as CEO) should have been filed earlier. If he had BRK holdings as a director, they would already be in EDGAR -- the absence confirms minimal or no holdings as of when he first became a BRK insider. Second, the $870M BHE proceeds create theoretical purchasing power, but six months have passed since his 2022 sale and he has not filed Form 4 for any BRK acquisitions -- suggesting he has not been buying in the open market. Third, the proxy filing timing is favorable: DEF 14A typically filed March-April 2026 is well within the July 15 resolution window. The 32% estimate reflects genuine residual uncertainty from the unknown compensation structure, while acknowledging the multiple absence signals.

The central question is whether the expected DEF 14A proxy filing (March-April 2026) will reveal >$50M in BRK holdings. The absence of a Form 3 is notable but not conclusive -- Abel's transition from BHE executive to BRK CEO may have involved a different Section 16 reporting structure, and some officers file late without penalty. The $870M BHE liquidity event in 2022 gave Abel substantial capital; it would not be unusual for an incoming CEO to hold a meaningful stake accumulated over years of service. However, the complete absence of Form 4 filings for any BRK transactions is the most telling signal. If Abel owned $50M+ worth of BRK shares before becoming CEO, those acquisitions should have generated Form 4 filings during his tenure as a BRK director (directors are Section 16 insiders). The resolution criteria includes the DEF 14A, which makes YES possible even without a Form 3. I arrive at 34% -- slightly below the prior 36%, reflecting the Form 3 absence as a modest downward revision.

Analyzing the updated evidence structure: the FY2025 10-K confirms Abel's holdings remain undisclosed and provides no new positive signal. The prior 0.36 was set on February 14 when the data gap was fresh -- since then, 16 additional days have passed without a Form 3 or Form 4 filing. The analytical question is whether Abel holds >$50M in BRK (approximately 96,000 B-shares or 64 A-shares). For this to resolve YES: either (1) he accumulated shares during his director tenure through compensation mechanisms not captured in Form 4 (possible but compensation for directors is typically disclosed differently), or (2) he negotiated an equity package as CEO that grants him shares in year one (possible but unprecedented at Berkshire). The traditional Berkshire CEO compensation is $100K cash -- any deviation would be notable. OxyChem acquisition activity suggests Abel is focused on deploying Berkshire capital, not personal capital, into BRK equity.

I maintain a relatively higher estimate within the ensemble because the resolution criteria includes the DEF 14A proxy statement, which is nearly certain to be filed before July 15, 2026. The question is not whether disclosure will occur -- it almost certainly will -- but whether the disclosed amount exceeds $50M. I note that Abel has been in the Berkshire ecosystem for decades and could have accumulated shares through director compensation, phantom equity arrangements, or personal purchases made before his Section 16 reporting obligation was triggered. The $870M BHE sale provides the financial context: a person with $870M in liquidity is unlikely to have zero BRK exposure heading into the CEO role. However, Berkshire's culture of minimal formal equity compensation and the absence of any Form 4 filings during his board tenure weigh against the $50M threshold being met. My estimate remains near the prior as the new information is confirmatory (absence persists) rather than decisively negative.

The FY2025 10-K update reinforces the 'no skin in the game' hypothesis. The strongest signal is the cumulative absence of Form 4 filings -- not just as CEO but as a longtime BRK board member and executive. Section 16 insiders must report acquisitions within two business days. Abel became a BRK director years before becoming CEO, which means any significant BRK stock accumulation during his board tenure would have generated Form 4 filings. The absence of these filings in EDGAR strongly suggests Abel has not been accumulating BRK equity. His BHE stake was a subsidiary investment, not BRK parent equity. For >$50M in BRK holdings to exist, Abel would need to have been granted shares by Berkshire (unprecedented at current compensation levels) or to have purchased them in a window not captured by Section 16 reporting (essentially impossible for a director/officer). The proxy will disclose whatever exists, but the evidence pattern points toward minimal holdings.

The FY2025 10-K filing provides two key updates: (1) Abel is formally named CEO effective January 1, 2026 -- no ambiguity about his Section 16 status -- and (2) no Form 3 has been filed as of the March 2 annual report. The resolution path that has the highest probability of YES is the DEF 14A disclosure, which is nearly certain to occur before July 15. The question is whether the proxy will show >$50M. Abel's compensation package remains undisclosed, but Berkshire's historical pattern of minimal CEO equity compensation makes a grant-based path to $50M unlikely. Open-market purchases would require Form 4 filings, none of which appear in EDGAR. I estimate 29% -- reflecting that the data gap persists but the negative signals (Form 3 absence, no Form 4 history, traditional Berkshire comp structure) collectively reduce the probability from the prior 36%.

I give slightly more weight to the possibility that Abel accumulated BRK shares through mechanisms that do not require Form 4 reporting. Specifically: (1) phantom equity or deferred compensation plans settled in BRK shares are sometimes structured to delay Section 16 reporting until settlement, and (2) beneficial ownership through a trust or family entity that was not required to report under earlier filing thresholds. The $870M from his 2022 BHE sale is notable context -- a person of that wealth holding zero BRK shares as incoming CEO would be an unusual statement. However, I acknowledge this reasoning is speculative and the absence evidence is strong. The proxy filing before July 15 is essentially certain, which converts this to a question of whether Abel's disclosed stake crosses $50M. I land at 33% -- above the median but acknowledging the structural negative signals.
