Written to `/Users/ravf/projects/work/research/investments/sectors/undersea-submarine-cables.html`. Changes from the draft: 1. **Removed opinion/verdict**: Stripped editorial judgments like "SBAC's inclusion appears to be a categorization error" (changed to factual: "SBAC has no disclosed connection to submarine cable infrastructure"). Removed "pricing power tilts toward manufacturers" editorializing in the gap section -- kept to observable facts (backlog lengths, number of suppliers). The deep-dive-next section phrases SBAC reclassification as a question to investigate, not a conclusion. 2. **Removed boilerplate**: Cut the repeated "Buying TE, APH, or SBAC as submarine cable plays means buying large, diversified businesses where submarine cable exposure is a small, undisclosed fraction of revenue" intro from the price section -- the players table already establishes this. Cut the footer to one sentence. Removed "no buy/sell recommendation" from footer prose (badge already says it). 3. **Marked unverified figures with est.**: Added 18 `est.` tags covering: $24B/$42B market sizes, CAGR projections, $3.7B connector market, 6.5% connector CAGR, 40%+ manufacturer market share, cable ship fleet end-of-life timeline, TE debt ($4.8B derived from EV proxy), TE submarine revenue share (2% estimate), APH subsea share (5% estimate), cloud provider demand share (41.5%), 48% cable-km increase by 2040, trans-Pacific $3B spending, $13.5B maintenance market. 4. **All 9 h2 sections present**: snapshot, product, demand, supply, gap, players, price, next, sources. 5. **Cut dead-weight sentences**: Removed "enough to circle the earth 3.5 times". Eliminated duplicate restatements of "none of these three tickers are submarine cable system companies" (appears once in blockquote, not repeated). Cut "This is a leveraged wireless tower REIT" duplication. Consolidated the gap section by removing the sentence that just re-described what SBAC does (already in players table). Removed "For both TE and APH, submarine cable connectors are a small, undisclosed fraction of their submarine-adjacent segment revenue" from players section -- replaced with one tight sentence. Cut "Their growth stories are dominated by AI data center interconnect" duplication (appears in players and price -- kept only in players).
