Corporate Change Comes in Bundles: Evidence from 200,000 Spanish Capital Operations

205,077 capital operations registered in Spain between 2021 and 2025 show that management change arrives in the same filing package as the capital operation — at roughly 65 times each company's own filing rhythm — and almost nowhere else.

Summary

Across 205,077 capital operations registered in the BORME — Spain's official companies gazette — between 2021 and 2025 (167,248 increases, 37,829 reductions), governance changes rarely cluster in the surrounding months. They frequently appear in the same filing package. A capital increase co-occurs with a governance change on the same day in 13.4% of cases, against a 0.2% baseline — roughly 65 times the rate produced by neutral dates; for reductions, 16.1%. Outside the filing day, the surrounding windows are statistically indistinguishable from each company's own filing rhythm: 12.1% against an 11.5% baseline in the 90 days before an increase, 6.0% against 6.6% after.

Essentially all of the excess co-occurrence — above what each company's normal filing rhythm produces — is concentrated on the filing day itself: +13.2 percentage points same-day, and approximately zero across the ±90-day windows.

The pattern is structural, not cyclical: the same-day rate for increases stays within 12.9%–14.3% in every year from 2009 to 2025, through the financial crisis recovery, COVID, and the post-pandemic period.

The bundling is also asymmetric. Seen from the governance side, of 1,304,292 governance-change filing days in 2021–2025, only 1.7% coincide with a same-company capital operation. Capital operations frequently carry management changes with them; management changes overwhelmingly travel alone.

The practical reading for due diligence: the information content of a capital operation is concentrated in the complete entry and that day's filings. Monitoring that focuses primarily on post-event governance changes may capture little incremental information beyond the original filing package.

Headline results (2021–2025)

For every capital operation we asked one binary question per window: did the same company register at least one governance change within 30, 90 or 180 days — before and after measured separately — or on the filing day itself? The baseline column applies identical windows to neutral dates drawn from each company's own history (see Methodology).

Baseline = identical windows placed on neutral dates within each company's own filing history.

Three readings of this table matter:

• The bundling is literal. 9.7% of capital increases and 11.7% of reductions share their BORME entry with a governance change — one notarial package, one entry. The same-day figure adds filings published the same day in a different entry on top.
• The apparent before/after asymmetry is an artifact. Increases show 12.1% before vs 6.0% after at 90 days — but the baseline shows the same shape (11.5% vs 6.6%). The asymmetry comes from span censoring: a company's last filings have history before them and silence after, and the baseline design reproduces that exactly. It should not be read as behavior.
• Reductions bundle harder but trail less: the highest same-day rate (16.1%), with surrounding windows at or below baseline throughout.

Stable for seventeen years

The same-day rate for capital increases stays within 12.9%–14.3% in every year from 2009 to 2025 — minimum 12.9% (2018 and 2025), maximum 14.3% (2014). COVID dented volume (27,885 capital acts in 2020), not the rate (13.9% that year). Reductions drift mildly down, from 20.0% in 2009 to 15.7% in 2025.

Legal form: bundling is the SL story; anticipation is the SA story

Spain's SLs (sociedades limitadas) — the overwhelming mass of Spanish companies — show no window elevation at all: their rate in the 90 days before a capital increase equals their own baseline. SAs (sociedades anónimas), the larger corporate form, are different: a genuine elevation of roughly 10 percentage points in the 90 days before a capital increase, against a baseline matched to the same legal form. In larger-form companies, management change does precede capital operations; in the SL economy, change arrives in the notarial package or not at all.

Baselines computed separately per legal form.

Amounts: bundled increases are smaller

Capital increases adjacent to a governance change are substantially smaller than increases without one: median €40,000 against €61,046 — consistent with founder-led and smaller-company transactions. Direct firm-size covariates (assets, employees, age) are not in the BORME, so this is an association, not a size-controlled result.

Publication lag: how tight is the gazette?

A by-product of the study: comparing the inscription date recorded in each entry's registry data with the BORME publication date, across n=203,914 capital acts, the lag is a median of 7 days, with a 90th percentile of 11 and a 99th percentile of 18 — stable across 2009–2025. Windows built on publication dates are therefore tight proxies for registration timing; the interval between the notarial deed and inscription remains unobservable.

The reverse view: governance changes travel alone

Of 1,304,292 distinct governance-change filing days in 2021–2025, 21,632 — 1.66% — fall on the same day as a capital operation of the same company. Bundling is a property of capital operations, not of management change in general: governance changes are roughly six times more frequent as events, and the overwhelming majority are filed with no capital context at all.

Methodology

Data. All capital operations published in the BORME from 2009 to 2025, with 2021–2025 as the headline window: 205,077 operations (167,248 increases, 37,829 reductions). Companies are tracked at the registry-sheet level, so re-registrations do not fragment a company's history. Amounts were re-parsed from the raw entry text; in the headline window, 250 acts (0.12%) had unparseable amounts and were kept and counted, never dropped.

Metric. One binary question per window: does the company register at least one governance change within 30, 90 or 180 days — before and after measured separately — or on the same day as the capital act? A binary metric avoids double-counting batch filings. Governance covers all officer roles except the power-of-attorney class (apoderados), which behaves differently and is analyzed separately.

Baseline. The key question is not whether companies that file capital operations also file governance changes — active companies file more of everything — but whether governance changes cluster around capital operations specifically. So for each company with capital acts, we placed up to three deterministic control dates inside its own filing history, each at least 180 days from any of its capital acts, and computed identical windows on them (a placebo-style control design): 923,291 baseline windows in total. This compares every company against its own filing rhythm, and is also computed separately per legal form for the form-matched comparisons.

Why this comparison is conservative. As a cross-check, the governance-change probability in one random 90-day window for a broad sample of active companies is 5.6% — well below the 11.5% within-company baseline, because companies that file capital acts are more registry-active in general. Measuring elevation against the within-company baseline therefore understates, rather than overstates, how unusual the same-day clustering is.

Exclusions. Three event families were excluded from the governance measure and tallied separately: re-elections of officers (Reelecciones, 783,263 — continuity, not change), administrative cancellations (Cancelaciones, 63,735 — registry cleanup), and modifications of powers of attorney (Modificación de poderes, 13,225).

Data and limitations

1. The BORME records registered legal events — not a company's economic condition, value, or the motivation behind an act. All findings are descriptive statements about filing behavior. No causal claims are made.
2. Dates are publication dates. The inscription-to-publication lag is small and stable (median 7 days; see above); the deed-to-inscription interval is unobservable. "Same day" means published the same day, which for bundled acts reflects same-deed or same-presentation registration.
3. Counts are position-level. Officer records in the source carry no officer names, so an entry appointing three board members of the same title yields one distinct record after deduplication. All headline rates are binary per window and unaffected; raw counts mean "distinct (company, date, direction, position) changes".
4. The before/after asymmetry in the baseline is censoring, reproduced identically in the treatment and baseline series. The baseline population is companies that file capital acts; the 5.6% population-wide rate brackets the comparison from below.
5. Role classes. Governance is defined as every role not matching the power-of-attorney prefix list, finalized against the full inventory of normalized position titles (June 2026). This includes auditors and representative roles; position strings are stored per record, so a stricter management-only cut can be recomputed from the snapshot without re-extraction.
6. Excluded from the governance measure, but tallied: Reelecciones 783,263 (continuity), Cancelaciones 63,735 (registry cleanup), Modificación de poderes 13,225.
7. The long-run series (2009–2020) rides on PDF-parsed source data with known extraction noise (a re-ingestion from the XML edition will supersede it); the 2021–2025 window is the defensible core. The year-series stability is robust to this.
8. Amounts come in two text formats plus a separate reduction format; 0.12% were unparseable in the headline window. "Accordion" operations (a reduction and increase in one entry) are parsed as separate acts.
9. SA baseline caveat: the form-matched baseline matches legal form but not company size within form. The SA results rest on n=8,373 acts against 75,222 baseline windows — ample, but the SA population is heterogeneous, from listed giants to small family companies.
