Most Market Share Shifts Are Visible 6 to 12 Months Before Revenue Changes

Marvin didn't lose South Florida overnight. Lead times crept first. Dealer support thinned. Then in November the closure notice landed: a 181-person plant in West Palm Beach, gone, Marvin out of the toughest hurricane zones for good.

By the time that hit the trade press, the share had already moved. The announcement was just the part everyone could finally see.

The problem isn't seeing the signal. It's knowing where to look.

Revenue, backlog, and win rate are the scoreboard. They tell you what already happened, usually six to twelve months after it started. The dealer who quietly picked up a second brand did it last spring. The competitor whose lead times stretched to 10-12 weeks did it because something broke upstream, and the buyers noticed before the P&L did.

If you're only watching revenue, you're reading last season's weather.

Your competitors are leaving a trail. Most leadership teams aren't reading it.

3 things move before revenue does. I look at all 3 before I look at a single revenue number.

Capacity

Lead time divergence is a forecast in disguise. Right now it's playing out in impact windows: 10-12 weeks at one major brand against 5-6 at a smaller rival. That gap doesn't show up in either company's earnings call. It shows up in which contractor starts quoting the faster option before hurricane season opens.

Channel

Dealers hedge before they defect. A contractor asking about a second supplier, or grumbling about limited product range, isn't a lost account yet. They're six months from being one. The Marvin exit started with dealers already diversifying. Not with the press release.

Portfolio

Watch what a parent company sunsets. When CGI's Sentinel and Estate lines disappeared and only Sparta survived under a new PGT structure, that wasn't a rebrand. That was Miter deciding where the growth actually is. The lines they cut tell you more than the lines they keep.

None of this shows up in a quarterly filing. It shows up in the field, in dealer conversations, in who's quoting what lead time this week.

You're not late to the market. You're late to the signal.

Waiting for revenue to confirm the shift is a strategy. It's just not a winning one.

The companies that picked up share from the Marvin exit didn't win because they reacted fast. They'd already made their move before the headline existed, because they were watching the right things 6 months earlier. That's the difference between a bet placed early and a reaction placed late.

What early signal are you watching right now? Lead times, dealer chatter, a product line getting quietly cut. Tell me what's on your radar. It's probably more useful than whatever's making headlines this week.
