Bullish deep-dive on Constellation Software arguing the 45% drawdown is an AI-narrative-driven buying opportunity with shares far below the author's estimated intrinsic value.

CSU.TO — LONG The author argues Constellation Software is deeply undervalued after a 45% drawdown, estimating intrinsic value at CAD 4,500-6,000 per share versus a recent CAD 2,845 price. He cites a 2027 estimated FCF yield above 8% and roughly 15% IRR at the current valuation as the basis for a long position. The main risk he acknowledges is that the market may keep applying an AI-disruption discount.

From my back of the napkin math, I believe the rough intrinsic value of each CSI share lands between $4,500-6,000 CAD, and it just closed at $2,845 CAD. The 2027 FCF yield based on estimates at the current valuation is 8%+ now and IRR at current valuation is about 15%.

CSU.TO — LONG The author argues the bear case that AI can easily replicate CSI's legacy software is wrong because its vertical market software is built on decades of customization, client relationships and niche industry workflows. He says these systems have survived mainframe-to-PC-to-web-to-cloud transitions and AI is only a minor weather event, so the AI-disruption discount should fade. The stated risk is that AI could still increase competition and pressure margins.

These legacy systems are basically bulletproof. They have survived the move from Mainframes to PC, PC to Web, and Web to Cloud. AI is just a minor weather event.

CSU.TO — LONG The author contends that AI cannot disrupt CSI because writing code is useless without proprietary data, systems of record and industry experience. He also points to high retraining, integration and operational switching costs, and notes software is below 1% of customer revenue, giving little incentive to migrate to unproven AI replacements. The stated risk is that AI could eventually lower switching costs or enable new entrants.

Sure, application softwares can be quickly written and made with some form of AI and tasks can be automated - but the code is meaningless or flat out impossible to write no matter how advanced AI is if there is no data or systems of records to go off of.

CSU.TO — LONG The author argues CSI is not an AI victim but a fast follower that already implements AI across portfolio companies and owns businesses that create mission-critical software. He claims this positions CSI to benefit from AI rather than be disrupted, supporting the long thesis. The stated risk is that the market may continue to ignore this and apply an AI threat discount.

CSI is not a slow innovator, as stated in the AI conference call, they are a fast follower. They already have AI enabled in their software in many of their businesses that can benefit from it.

CSU.TO — LONG The author says CSI's M&A pipeline remains intact and AI can help source or create acquisitions, supporting future growth. He argues this reinforces the long case because CSI's acquisition strategy continues despite the AI narrative. No specific risk for this point is stated beyond the overall AI-disruption concern.

The M&A pipeline remains intact, and AI can actually help with finding acquisitions or creating companies to acquire.

CSU.TO — LONG The author believes the management change deserves only a minor drawdown, not the 45% decline, because Mark Leonard remains on the board and CSI has a deep bench of long-tenured leaders. He contrasts the selloff with Berkshire's smaller drawdown after Buffett's departure. The stated risk is uncertainty over how long Mark Miller will stay at the helm.

A final note, regarding the management change - I truthfully think this is the one thing that does deserve a minor drawdown of the stock, but not 45%.

CSU.TO — LONG The author cites Mark Miller's CAD 5 million open-market purchase of CSU in December as evidence that the management change selloff is overdone. This insider buying signal supports his long thesis and suggests management sees value at current prices. The stated risk is that the market may remain focused on the CEO transition.

Mark Miller recently made an open market purchase of 5M CAD of CSU back in December.
