Value investor Christopher Bloomstran’s firm, Semper Augustus, significantly reduced its holding in engine manufacturer Cummins Inc. (CMI), according to a recent disclosure. The filing reveals a 67.18% reduction in the firm's position, decreasing its share count from 39.53K to 12.97K. The reported value of the stake fell from over $21 million to approximately $9.25 million.

Investors should note that 13F filings are delayed, reflecting trades made during the second quarter, which ended June 30, 2026. During that period, Cummins reported record second-quarter revenues of $9.5 billion and raised its full-year guidance, driven by strong demand in data center power and North American truck markets. The company's stock, however, saw a drop after its GAAP profit missed analyst estimates.
