Cellnex stock (ISIN ES0105066007) closed at EUR 25.71 on the BME on September 21, 2026, gaining 2.84 percent from the previous close. The move followed BlackRock's increase in its holding to 6.398 percent, while Cellnex reported first-half revenue of EUR 2,209 million.

BlackRock raises its position

According to Alicante Plaza on September 22, 2026, BlackRock increased its Cellnex holding to 6.398 percent. The position represented 42.49 million shares valued at approximately EUR 1.094 billion, compared with a previously reported stake of 5.001 percent.

The market reaction was visible in the September 21 close: Cellnex rose EUR 0.71, or 2.84 percent, from the prior close to EUR 25.71. The stake disclosure therefore arrived alongside a measurable price move rather than as an isolated ownership update.

Revenue and EBITDA move higher

According to Alicante Plaza on September 22, 2026, first-half revenue increased 2.9 percent year over year to EUR 2,209 million. Consolidated reported revenue rose 2.7 percent to EUR 1,994 million, while EBITDA after leases increased 7.7 percent to EUR 1,231 million.

The operating split adds detail to that comparison. Tower revenue reached EUR 1,625 million in the first half of 2026, with organic growth of 5.2 percent, while the net loss narrowed 15.6 percent to EUR 97 million. The combination of higher EBITDA and a smaller loss points to operating improvement, although the bottom line remained negative for the period.

2026 targets set the next test

Cellnex's 2026 targets call for revenue of EUR 4,075 million to EUR 4,175 million and adjusted EBITDA of EUR 3,425 million to EUR 3,525 million, according to Alicante Plaza on September 22, 2026. The next scheduled quarterly accounts are due on November 5, 2026, providing the next dated checkpoint for progress against those ranges.
