Old Second Bancorp’s Insider Buying Frenzy: CFO, CEO, & VPs Stack Shares Ahead of Q1 Earnings Surprise

Insider Activity at Old Second Bancorp – What Investors Should Watch

Adams Bradley’s Latest Purchase Signals Confidence

On March 31, 2026, CFO & COO Adams Bradley S. added 35 shares to his holding through the employee salary and savings plan at a price of $0.00 per share. Although the transaction size is modest, it comes at a time when the stock is trading at $20.45—its first‑quarter high for the year—and the company is on the cusp of delivering its Q1 2026 earnings. The buy is the latest in a series of small, regular acquisitions that have kept Bradley’s stake at roughly 160 k shares (about 15 % of outstanding shares). This pattern suggests a long‑term commitment to the company’s upside, particularly as the bank’s earnings guidance is expected to rise with the ongoing expansion of its Illinois‑based mortgage and trust services.

Broader Insider Activity Adds Context

While Bradley’s transaction is minor in isolation, it sits alongside a flurry of activity from other senior executives. The vice chairman, Gary Collins, recorded four purchases totaling over 23,000 shares in March, and the CEO, James Eccher, made two sizeable buys of 391 k shares in total during the same month. These moves, combined with the EVP purchases from Donald Pilmer and Richard Gartnermann, indicate that the top leadership team is actively aligning their personal portfolios with the company’s prospects. For investors, the convergence of buy‑side activity across multiple executives can be interpreted as a bullish signal, especially when the company’s price‑to‑earnings ratio of 12.21 remains comfortably below the sector average.

Implications for Shareholders and the Market

The timing of Bradley’s purchase—just days before the April 1 8‑K filing and the upcoming earnings release—raises the possibility that insiders are anticipating a positive earnings surprise. If the company indeed beats expectations, the stock’s weekly gain of 4.28 % and a 38 % year‑to‑date rise are likely to accelerate. Conversely, if the earnings miss, the insider buying could be seen as a vote of confidence that may cushion a sharp downturn. Market analysts should monitor the subsequent trading volume; a spike in volume following the earnings call would validate the insider sentiment captured by the 377 % social‑media buzz.

Adams Bradley’s Transaction Pattern

Bradley’s historical trades show a consistent pattern of modest, frequent purchases—most recently buying 15,657 shares in early March and adding 35 shares in March 31—interspersed with occasional sales that keep his holdings close to a 15–16 % stake. The lack of large sell orders suggests that Bradley is not in a hurry to liquidate; instead, he appears to be building a position in line with the company’s long‑term value creation strategy. This disciplined approach is typical of CFOs who use insider activity to reinforce investor confidence, and it aligns with his role in overseeing the bank’s financial strategy and risk management.

Key Takeaway for Investors

Adams Bradley’s latest purchase, coupled with concurrent buying by other senior executives, signals a shared belief that Old Second Bancorp’s fundamentals are improving. For investors, this insider buying pattern—set against a backdrop of positive earnings guidance and a strong stock performance—provides a compelling reason to stay bullish. However, staying vigilant about the company’s forthcoming earnings and any shifts in insider sentiment will be critical to navigating the next few months of market volatility.
