Security 101's 2026 'Momentum' Is Real — You Just Can't Buy the Stock

Every few months some company puts out a press release that reads like a stock picker's dream: expanding leadership, a string of acquisitions, "momentum." Security 101's September 10 headline did exactly that — promoting Craig Shulman from chief financial officer to chief operating officer, installing new regional sales directors, and ticking off five 2026 deals across Utah, Hawaii, Northern and Southern California, and South Carolina, all while the company said it nearly tripled its revenue over two years.

Before you go hunting for the ticker, consider what Security 101 actually is: a private company. There is no Security 101 share to buy. That one fact reshapes everything the announcement is trying to tell you.

Security 101 is a commercial security systems integrator — it designs, installs, and maintains the access-control systems, video surveillance, intrusion detection, and visitor management that keep commercial buildings secure. Its customers sit in healthcare, education, government, and finance, organizations that can't afford a breach and don't run the hardware themselves. It says it operates more than 50 U.S. locations out of West Palm Beach, Florida.

That business model is precisely why this is a private-equity story rather than a public one. Commercial security integration is fragmented across thousands of local firms. A well-run platform buys those local operators — and, in Security 101's case, its own former franchisees — rolls them onto shared systems, and layers on the national accounts that individual locals can't serve. The kicker is the revenue isn't one-time installation work. Monitoring and maintenance contracts produce a recurring stream of fees, the "resilient, services-oriented" cash flow that private equity explicitly buys.

That is exactly who bought it. In February 2026, Morgan Stanley Capital Partners — the middle-market buyout team inside Morgan Stanley Investment Management closed its acquisition of Security 101 from Gemspring Capital, the private-equity firm that had owned the company since 2022. The deal closed on February 19, with William Blair advising the seller. So every "national acquisitions" bullet point since then is a portfolio company spending someone else's capital to consolidate a market.

Here is where the momentum framing needs a reality check. As a retail investor, you have no stake in it — because you can't. The near-tripled revenue and the leadership promotions are private-market facts reported to a private owner for whom a bigger company is the exit. The value being created accrues to Morgan Stanley's funds and to whoever acquires Security 101 next, not to any public shareholder. A release that looks like a growth-stock pitch is actually a progress report on a private roll-up: useful as a signal about the sector, useless as a call to action.

What the public bar for this theme looks like is instructive, and it is a reminder of why "cheap" and "expensive" only mean something beside a comparison set. The closest listed proxies for security-services revenue trade at wildly different prices. ADT, the security-systems name that leans on recurring monitoring, carries roughly a $5 billion market cap, about 4.7 times trailing EV/EBITDA, and a dividend yield above 4%. Johnson Controls, the diversified buildings giant that sells security alongside HVAC and fire systems, trades nearer 25 times EV/EBITDA. Neither is a clean surrogate for a commercial integrator — different margins, leverage, and growth — which is exactly the point: there is no public number with which to value Security 101, because its momentum was never for sale to you.

So the honest takeaway is a process check, not a buy signal. The "rally" in this headline is real, but it is a private rally, captured by private capital. When you see a roll-up story like this one, the discipline is the same you would apply to any stock you can actually own: build a comparison set, weigh valuation against growth and profitability, confirm with revisions and momentum — and, first, verify who owns the value being created and whether ownership is even on the table. For Security 101, it is not. Treat the momentum as an industry indicator, then go find the public shares where the value is actually priced for you.
