The Overview

T-Mobile is one of three companies that own a nationwide mobile phone network in the United States. About 108 million people pay it every month for phone service, and increasingly for home internet delivered over the same wireless network. It is a very large, very steady business: about $92 billion of revenue over the last twelve months and about $28 billion of cash generated from operations last year.

For most of the last decade T-Mobile was the one telephone company that was actually growing. It won customers from the other two every quarter, and it told investors exactly how many it won, in a number called "postpaid phone net additions". Investors paid a premium for the shares because of that number.

Two things have happened. First, the growth slowed down, and to keep growing T-Mobile started buying other companies — a regional carrier called UScellular last August, and stakes in several fibre-broadband companies. Buying customers is not the same as winning them. Second, and this is the part that matters most, from the March 2026 quarter the company stopped publishing that headline growth number altogether. It now reports a broader measure based on billing accounts instead. That number went down 13% in the June quarter, and the percentage of customers leaving went up.

The share price has responded. The shares are $177.21. A year ago they were near $259. That is a fall of about 32%, at a time when the US stock market as a whole rose about 24%. Being 56 percentage points behind the market in a company that sells something as unglamorous and essential as phone service is not normal, and we are not going to pretend it is a buying signal by itself.

But the numbers have got cheaper faster than the business has got worse. Analysts expect the company to earn about $13.90 a share in 2027, which means you are paying about 12.8 times those earnings today. And the reported profit for the first half of this year looks worse than it is: it fell 7%, but almost all of that is one-off costs from absorbing UScellular. Strip those out — the company tells you exactly what they are — and the underlying profit actually rose about 9%.

There is also a very large amount of cash coming back to shareholders. The board has approved up to $18.2 billion of share buybacks and dividends for this year. Against a company worth $190 billion, that is about 9.6% of the whole company being handed back in twelve months. The dividend alone is $1.02 every three months, which is $4.08 a year, or a 2.3% yield.

Our estimate of what the shares are worth is $208. They cost $177.21, so that is about 17% of upside. The catch is that the average analyst thinks $235.50 — well above our number — and when we are below the crowd on a share price that is still falling, the usual next event is that the crowd's number comes down, not that the price goes up. There is also no company news due for another 79 days.


Putting a number on it: our fair-value estimate is $208 against a current price of $181.37 — real upside if our numbers are right.

Our summary metrics

Downside Risk (lower = safer)5/10Moderate

"Rated 5 — genuinely levered, genuinely cash-generative, and cheap enough now that the valuation is a support rather than a risk. The negatives are real and several are structural. Corrected net debt is $84.1B against rebuilt trailing EBITDA of $33.128B — 2.54x, or 3.62x if the roughly $36B of operating lease liabilities is added — against a credit-agreement maintenance covenant of 4.5x, with which the company states it was in compliance at 2026-06-30. Interest expense is running at $1.055B a quarter and rose 14% year on year; the weighted-average effective interest rate went from 4.1% to 4.3%. Deutsche Telekom held approximately 52.8% of the stock and voting control over approximately 56.9% as of 2026-02-06, so minority holders do not control the outcome of anything, and two separate shareholder derivative suits over the stockholder return programmes are outstanding. Roughly $100.7B of the $219.2B asset base is spectrum licences — indefinite-lived intangibles tested only qualitatively, which the 10-K confirms was the method used at 2025-12-31. The company has been the subject of two disclosed cyberattacks and updated that risk factor again in the June 10-Q. And $5.0B to $7.2B of committed strategic outflows sit outside every vendor field: approximately $700M for the i3 Broadband joint venture in the second half of 2026, approximately $2.0B for the Oak Hill fibre joint venture in the first half of 2027, approximately $500M more for Lumos between 2027 and 2028 (explicitly excluded from the reported purchase-obligation table), a $420M Ka'ena earnout in the second half of 2026, $222M of Auction 113 spectrum paid on 2026-07-24, and $1.2B to $3.4B remaining under the Comcast 600 MHz agreement targeted at the first half of 2028. Against all of that: beta is 0.319, the business is a regulated-utility-like duopoly-plus-one with $92.2B of trailing revenue, operating cash flow ran $27.95B in FY2025, the revolver is $10.0B and undrawn, the $2.0B commercial paper programme is undrawn, and at 12.75x forward earnings there is not much multiple left to lose. A 5, not a 4, because the leverage is real and the subscriber trend is deteriorating; not a 6, because the cash flows are among the most predictable in the S&P 500."

Growth Quality5/10Moderate

"Rated 5 — the reported growth is acquisition arithmetic and the organic signal is deteriorating, but the earnings underneath are better than the headline. FY2025 revenue was $88.309B, up 8.5% on FY2024's $81.400B, and the 10-K attributes essentially all of it to acquired assets: postpaid revenue up $5.6B or 11% 'primarily from higher average postpaid accounts, including following the acquisitions of UScellular, Metronet and Lumos', with UScellular alone contributing 3,287,000 postpaid phone customers in the third quarter of 2025. Underneath that, prepaid revenue rose 1% on falling ARPU, wholesale and other service revenue FELL 16%, and postpaid phone churn rose 7 basis points. In 2026 the deterioration is clearer: June-quarter revenue $22.791B, up 7.9%; postpaid revenue up 13%; but prepaid revenue DOWN 6%, wholesale and other service revenue DOWN 8%, postpaid net account additions DOWN 41,000 or 13% with churn up 7 basis points on 'higher industry switching', and reported first-half net income DOWN 7.0%. The most important disclosure fact in the file: 'Beginning with the three months ended March 31, 2026, we shifted away from reporting customer performance measures' — postpaid phone net additions, present throughout the FY2025 10-K, are simply gone. Consensus has revenue growth decelerating to 6.9% in 2026, 4.4% in 2027, 4.0% in 2028 and 3.3% by 2030. What keeps this at a 5 rather than a 3 is that operating income still grew 5% in the June quarter, postpaid ARPA rose $3.04 or 2%, Core Adjusted EBITDA rose 12%, and clean first-half net income — adding back $622M of UScellular merger-related costs, $149M of Network Restructuring and $105M of Workforce Transformation severance, all net of tax and all disclosed — rose 8.6%. The growth is not gone; the growth PREMIUM is gone."

Exponential Potential3/10Low

"Rated 3 — a scaled network utility with two adjacent option values and no slope. T-Mobile's core business grows with US household formation, price increases and share shift, all of which are bounded. The two genuinely new things are 5G fixed-wireless broadband, where 5G broadband customers reached 7,602,000 at 2025-12-31 against 5,742,000 a year earlier, and residential fibre, entered through 50/50 joint ventures rather than owned build — Lumos (closed 2025-04-01, $932M for 50% and 97,000 customers), Metronet, i3 Broadband (approximately $700M, second half of 2026) and GoNetspeed/Greenlight (approximately $2.0B, first half of 2027). Those add customers and revenue, but they also add capital calls, equity-method LOSSES that the June 10-Q says drove Other expense, net up 873% for the quarter, and — critically — broadband-only accounts that the filing names as a direct cause of the RISE in postpaid account churn. The knowledge base's only forward-looking claims about this company are AI-RAN claims sourced to a supplier's chief executive predicting that base-station infrastructure will be 'completely reinvented as AI infrastructure running AI at the edge'. That is a supplier's revenue thesis, not a carrier's margin thesis, and we weight it accordingly. A 3: the network is essential, the demand is inelastic, and neither of those is an exponential."

Fair value$208 $131–$259
What does “fair value” mean?

Fair value is Synthos’s estimate of what one share is worth today, based on our model of the company’s future cash generation and the risks to it. It is not a price target or a prediction of where the stock trades next quarter — it’s the price where we think risk and reward are balanced. Above it, you’re paying for outcomes better than our base case; below it, the market is offering a margin of safety.

The model’s inputs and weightings are proprietary — they’re the product. What we publish is the output, plus an independent, public-math cross-check further down the page (“Check our number”) so you can judge it for yourself.

What do the 5 tiers mean? (Core · Tactical · Watch · Hold · Avoid)
Buy — CoreOwn it as a foundation — start or add now, size it for years, let dips be gifts.
Buy — TacticalGood price + confirmed trend + a defined exit — buy the setup, not a marriage.
WatchWe want the business, just not at this price/setup — act only when the listed trigger hits.
HoldFine to keep if you own it — no reason to buy more; new money does better elsewhere.
AvoidDon't own it — the problem is the business or the expectations, so a cheaper price won't fix it.

"The chart is broken and nothing in the near term fixes it. At $177.21 the stock is 31.6% below its 52-week high of $259.01, 5.7% above its 52-week low of $167.73, at the 10th percentile of its annual range, 3.2% BELOW a 50-day average of $183.04 and 10.7% BELOW a 200-day average of $198.56. RSI is 42.2 — weak but NOT oversold, so there is no mechanical bounce signal. MACD is −2.17. Twelve-month return is −25.3% against SPY +24.3% and QQQ +30.8%, a 49-to-56 point relative loss; three-month −8.9% against SPY +7.6%; six-month −9.1% against SPY +11.1%. Maximum drawdown from the six-year peak is −35.0%, meaning the current price IS the low of the drawdown. On 2026-08-04 the stock closed up 0.07% at $177.21 on 5.22M shares against a 5.48M average — a completely inert day inside a sector-wide semiconductor melt-up that lifted MRVL 12.8% and INTC 10.9%. T-Mobile did not participate in anything. The offset is the buyback: the company repurchased $7.1B of stock in the first half at an average of $203.07, $2.2B in the June quarter at $188.76, and $392M between 1 and 17 July at $182.53 — every tranche above today's price — with up to $8.5B still authorised through 2026-12-31. That is a large, price-insensitive, disclosed bid. It has not stopped the decline."
What we’re watching
"Whether the 52-week low of $167.73 holds. Whether the 50-day average of $183.04 is reclaimed, which would be the first evidence the downtrend has broken. The 2026-10-22 print against consensus revenue of $23.157B and EPS of $2.86 — note that the consensus EPS is BELOW the $2.99 just delivered, so the street is already modelling a sequential decline. Postpaid net account additions and postpaid account churn, which fell 13% and rose 7 basis points respectively in the June quarter. Whether the Grain 800 MHz spectrum sale — FCC-approved 2026-07-01, $2.9B of cash consideration against approximately $850M of incremental cash tax — actually closes in the third quarter as targeted. And whether the street's $235.50 consensus target starts coming down toward our $208, because an 11.7% gap between our number and theirs on a falling stock usually closes from their end."

Medium term 6-24 months

"The medium term is a straight test of whether consensus earnings are achievable on decelerating revenue. Consensus wants EPS of $10.904 in 2026 (17 analysts), $13.896 in 2027 (17) and $16.669 in 2028 (13) — a 52.9% rise over two years — on revenue growth of 6.9%, 4.4% and 4.0%. The arithmetic underneath is that implied net margin expands from the 12.45% T-Mobile actually delivered in FY2025 to 14.98% in 2027 and 16.47% in 2028, roughly 400 basis points, while the implied share count falls from 1,112M to 1,013M, roughly 8.8%. So about three-quarters of the EPS growth is margin and one-quarter is buyback. The margin leg has a real mechanism behind it: UScellular integration costs peak and roll off — substantially all restructuring and integration costs are expected to be incurred by the end of fiscal 2027 — and those costs are why reported first-half net income fell 7.0% while clean first-half net income rose 8.6%. The buyback leg is funded and disclosed: up to $18.2B for calendar 2026 and up to approximately $30.0B for share repurchases and cash dividends across 2026-2027, plus a stated 'over $22.0 billion in a discretionary and flexible envelope'. What argues against: FY2025 free cash flow looks like it grew 80% on the vendor's own numbers and the 10-K says Adjusted Free Cash Flow grew 6%; the first-half 2026 figure grew 4%. If Adjusted Free Cash Flow is compounding at 4-6% and the company intends to return roughly $18B a year against it, the gap is funded by asset sales and the balance sheet."
What we’re watching
"Whether UScellular merger-related costs actually roll off on the stated schedule — they were $622M net of tax in the first half of 2026 against $35M in the first half of 2025, so this is the swing factor in reported earnings. Whether postpaid account churn stabilises or keeps rising on the broadband-only mix the filing blames it on. Whether the fibre joint ventures stop being an Other-expense drag; equity-method losses drove Other expense, net up 873% in the June quarter. Whether the roughly $5.0B to $7.2B of committed strategic outflows (i3 Broadband, Oak Hill, Lumos top-up, Ka'ena earnout, Auction 113, Comcast spectrum) is funded from cash flow or from further debt, with cash already down from $5.6B to $2.8B in six months. Whether the 4.5x leverage covenant stays comfortable if EBITDA disappoints. And whether the street's 2027 EPS of $13.896 — which requires a 27.4% jump — survives contact with a 4.4% revenue year."

Long term 2+ years

Neutral
Driver
"Long-run, T-Mobile is one of three national US wireless networks, with the spectrum position the Sprint merger created and roughly $100.7B of spectrum licences on the balance sheet. That position does not erode quickly and the 10-K's own risk factors describe spectrum as scarce and appreciating in the secondary market — a view corroborated from an independent direction by the one knowledge-base claim in the file about spectrum as an asset class. The strategic question is whether wireless remains a three-player oligopoly. Two of the three genuine knowledge-base claims bear on this and they point in different directions: one argues satellite direct-to-cell 'could become a comprehensive global carrier' while conceding 'existing carriers won't be put out of business'; the other two argue the base-station layer gets rebuilt as edge AI infrastructure, which is a capital-expenditure claim, not a returns claim, and it comes from a supplier. The company's own long-run plan is visible in the capital allocation: approximately $30.0B of shareholder returns and 'over $22.0 billion' of discretionary capacity across 2026-2027, against fibre joint ventures that add customers without adding owned network. That is a company converting a mature network into cash and buying an option on fixed-line convergence."
What we’re watching
"Whether spectrum values hold — the 10-K's impairment test on $100.7B of indefinite-lived licences is QUALITATIVE, so an impairment would arrive as a shock rather than a trend. Whether Deutsche Telekom, at 52.8% economic and 56.9% voting, ever changes its posture; the filing warns explicitly that DT's interests 'may differ from the interests of other stockholders' and that future sales of stock by DT are a risk. Whether direct-to-cell satellite service becomes a substitute for terrestrial coverage rather than a complement to it. Whether the fibre joint-venture structure converts to owned assets and at what price. Whether the cable operators' mobile virtual network businesses keep taking share — the June 10-Q attributes falling wholesale revenue to 'lower MVNO revenues', which cuts the other way and is worth watching. And chief-executive continuity: Srinivasan Gopalan is named in the file as President and Chief Executive Officer, with a Chief Enterprise Officer hired externally effective no later than 2026-10-14 and a twenty-year Chief Business and Product Officer stepping away on 2026-07-08. That is a substantially reconstituted leadership team inside twelve months."

Next earnings2026-10-22 (third-quarter 2026 earnings, 79 days away; vendor consensus revenue $23.157B and EPS $2.86, implying +5.5% revenue growth year on year and −4.3% sequentially on the June quarter). The second quarter was reported 2026-07-23, twelve days before this dive, so the most recent hard data is fresh and there is no company-specific event for almost three months.

1. What the business is, and how the disclosure actually works

T-Mobile US, Inc. is headquartered at 12920 SE 38th Street, Bellevue, Washington. The profile lists Srinivasan Gopalan as chief executive — corroborated by the 8-K of 2026-07-07, which refers to "Srinivasan Gopalan, the Company's President and Chief Executive Officer." The 10-K states the company employed approximately 75,000 full-time and part-time employees at 2025-12-31, matching the vendor's fullTimeEmployees field exactly. Listed on NASDAQ Global Select; CIK 0001283699; CUSIP 872590104; ISIN US8725901040; common stock par value $0.00001.

A note on the vendor's company description, which is badly stale. It states network scale "As of December 31, 2021" and a subscriber count of approximately 108.7 million, and it does not mention UScellular, the fibre joint ventures, or the change of chief executive. It should not be used for any factual claim in this dive and it is not.

One reportable segment — which settles the seg_prod question before it arises

The 10-K states, in Note 1: "We operate as a single operating segment." The June 10-Q's Note 11 – Segment Reporting says "The following table provides the operating financial results of our Wireless segment" — singular.

This matters because it makes the usual segment/product confusion impossible in one direction and certain in the other. The vendor's seg_prod block cannot be the reportable-segment table, because the reportable-segment table has one line. What seg_prod actually is, is the revenue-disaggregation table from Note 11 – Revenue from Contracts with Customers. We say so explicitly rather than presenting it as a segment table.

And it reconciles exactly. We checked every year.

Four consecutive years summing to the dollar. And every line change matches the 10-K MD&A verbatim: "Postpaid revenues increased $5.6 billion, or 11%" (we compute +$5.592B, +10.7%); "Prepaid revenues increased $98 million, or 1%" (+$98M, +0.9%); "Wholesale and other service revenues decreased $562 million, or 16%" (−$562M, −16.3%); "Equipment revenues increased $1.7 billion, or 12%" (+$1.709B, +12.0%); "Other revenues were essentially flat" (+$72M). This is one of the cleanest vendor-to-filing reconciliations in this batch and it is worth recording as such.

One exception, and we flag it rather than smooth it. The FY2021 row does not sum: five lines total $77.795B against reported FY2021 revenue of $80.118B, a $2.323B shortfall (2.9%). The FY2020 and FY2019 rows contain a sixth line, "Roaming and Other Service Revenue" ($2.078B in FY2020), which is absent from FY2021 onward. The FY2021 disaggregation row is incomplete and is not used anywhere in this dive.

seg_geo is EMPTY. No geographic breakdown is supplied. T-Mobile operates in the United States, Puerto Rico and the US Virgin Islands only, so the economic loss is small — but the field is blank and we state that rather than implying we checked it.

The three eight-Ks — read in full, and none of them is what the pattern predicted

The archive contains three 8-Ks filed inside five weeks. A cluster like that on a company with $86.9B of debt normally signals a financing or an acquisition. It does not here, and we read all three end to end to establish that.

What the 8-K cover pages DO give us, and it is useful: the list of securities registered under Section 12(b) enumerates twelve separate exchange-listed senior note series — 3.550% due 2029; 3.700%, 3.150% and 3.200% due 2032; 3.625% due 2035; 3.850% due 2036; 3.500% due 2037; 3.900% due 2038; 3.800% due 2045; 6.250% due 2069; and two 5.500% series due March 2070 and June 2070. A 2070 maturity on an exchange-listed note is a fact about this capital structure that no vendor field carries.

Ownership and control

As of 2026-02-06, Deutsche Telekom AG held, directly or indirectly, approximately 52.8% of the outstanding T-Mobile common stock, and — through the Proxy, Lock-Up and ROFR Agreement with SoftBank dated 2020-04-01 — had voting control over approximately 56.9%. SoftBank ceased to be a related person on 2025-08-06. The 10-K's risk factors state plainly that "DT controls a majority of the voting power of our common stock and the T-Mobile trademarks we utilize in our business and may have interests that differ from the interests of our other stockholders."

This is a controlled company. Minority shareholders do not decide anything, and the T-Mobile brand itself is licensed from the controlling shareholder. Two shareholder derivative actions naming DT are outstanding — Dinkevich v. Deutsche Telekom AG (2021, over the Sprint merger repricing) and Palkon v. Deutsche Telekom AG (2025, over the 2022 Stock Repurchase Program and the 2023-2024 Stockholder Return Program).

2. The single most important thing to understand about these numbers: the metric that disappeared

Buried in the Performance Measures section of the June 10-Q, in one sentence with no emphasis, is the most consequential disclosure in this file:

> "Beginning with the three months ended March 31, 2026, we shifted away from reporting customer performance measures to better align with the Company's long-held priority on growing high-value accounts, which management believes is the best reflection of value creation versus customers."

T-Mobile has stopped reporting postpaid phone net customer additions.

That number is present throughout the FY2025 10-K. It is discussed by name — "Higher postpaid phone net customer additions, primarily from higher gross additions, partially offset by higher churn and increased deactivations from a growing customer base" — alongside postpaid phone churn ("increased 7 basis points, primarily due to higher industry switching") and postpaid phone ARPU ("increased $1.02, or 2%"). In the two 10-Qs filed since, it is gone. A grep of the June 10-Q for "postpaid phone" returns nothing.

What replaced it, and what the replacement says. The company now reports postpaid accounts, postpaid net account additions, postpaid account churn and postpaid ARPA. Here is what those show for the June quarter, verbatim:

> "Postpaid net account additions decreased 41,000, or 13%, for the three months ended June 30, 2026, primarily from: Higher account deactivations driven by the impact of a growing account base, including following the UScellular Acquisition, and higher average broadband-only accounts."

> "Postpaid account churn increased 7 basis points for the three months ended June 30, 2026, primarily from higher average broadband-only accounts, including following the acquisition of Metronet."

> "Postpaid account churn increased 9 basis points for the six months ended June 30, 2026, primarily from: Higher average broadband-only accounts... and Higher industry switching."

Three things follow and they are the whole bear case.

First, an account-level metric is structurally flattering and the company chose it. An account can contain many customers; ARPA rises when customers per account rises even if the company adds no customers at all. The 10-Q says exactly that: postpaid ARPA rose because of "An increase in customers per account, including from the continued adoption of 5G broadband and continued growth of T-Mobile for Business accounts." Moving from a customer metric to an account metric at the precise moment the customer metric turns is a choice, and we treat it as information about the customer metric.

Second, even the flattering metric is deteriorating. Net account additions down 13% in the quarter and 6% in the half; churn up 7 basis points in the quarter and 9 in the half; and one of the two named causes of the half-year churn increase is "Higher industry switching" — that is competitive, not mix.

Third, the fibre and broadband push is itself a churn source. The filing names "higher average broadband-only accounts" as the primary driver of rising churn in both periods. The growth initiative and the retention problem are the same accounts.

We are not saying the company is hiding a collapse. Postpaid revenue still grew 13% in the quarter, ARPA still rose $3.04, and Core Adjusted EBITDA still rose 12%. We are saying that the premium multiple T-Mobile carried was underwritten by a specific published number, that number is no longer published, and a 31.6% de-rating is a proportionate market response to that. Section 6 asks whether it is an over-response.

3. Growth and margin trajectory — and why the reported earnings understate the business

FY2025$88.309B+8.5%$18.744B21.2%$10.992B12.4%$9.721,131.1M

Read that table honestly and two facts stand out. The margin transformation happened in FY2023 — Sprint integration completing — and has now stalled: operating margin peaked at 22.1% in FY2024 and slipped to 21.2% in FY2025. And FY2025 net income FELL, from $11.339B to $10.992B, while revenue rose 8.5%. The 10-K's own summary: "Net income... was $11.0 billion and $11.3 billion for the years ended December 31, 2025 and 2024", with FY2025 including $293M net of tax of Workforce Transformation severance and $208M net of tax of impairment on capitalised software for the billing system ($278M pre-tax).

Also note the share count: 1,255.4M diluted in FY2022 down to 1,131.1M in FY2025 — a 9.9% reduction in three years, and 1,082.4M in the June 2026 quarter, a further 4.3%. The buyback is doing real work.

Q2 2026$22.791B+7.9%$5.490B+5.3%$3.239B$2.991,082.4M$2.99 vs $2.59

The vendor's operating income reconciles to the filing exactly. The 10-Q states operating income "increased $277 million, or 5%, for the three months ended and was relatively flat for the six months ended June 30, 2026." Vendor: $5.490B less $5.213B = +$277M, +5.3%. Six months: $9.987B against $10.013B, −$26M. Both confirmed.

Now the point the brief asked us to test. The EPS sequence 1.88 → 2.27 → 2.99 looks like a violent operational ramp. It is not. Compare year on year instead of sequentially:

So the "ramp" is fourth-quarter seasonality reversing, plus a buyback. Fourth quarter is device-heavy and promotion-heavy; it is always the weakest earnings quarter. There is no discrete gain in the sequence — we looked for one and did not find one. The 10-Q's own summary of the half is the honest read: "Net income... was $5.7 billion and $6.2 billion for the six months ended June 30, 2026 and 2025, respectively." Reported net income fell 7.0%.

The clean-earnings correction — and it runs the other way

The reported decline is almost entirely disclosed, itemised, after-tax integration cost. The 10-Q lists them:

> "UScellular merger-related costs, including accelerated depreciation, net of tax, of $146 million and $622 million for the three and six months ended June 30, 2026, respectively, compared to $25 million and $35 million... for the three and six months ended June 30, 2025"

> "A gain related to the completed sale of a portion of our 3.45 GHz spectrum licenses, net of tax, of $113 million, for the three and six months ended June 30, 2025"

> "Costs associated with our Network Restructuring Initiative, including accelerated depreciation, net of tax, of $46 million and $149 million"

> "Severance and related costs associated with the 2025-2026 Workforce Transformation, net of tax, of $105 million for the six months ended June 30, 2026"

Reported growth+0.5%−7.0%

Reported first-half earnings fell 7.0%. Clean first-half earnings rose 8.6%. That 15.6-point gap is the single largest analytical fact in this dive, and it points the opposite way to the share price.

Clean trailing EPS. Trailing-twelve-month reported net income is $10.560B (Q3 2025 through Q2 2026), or $9.55 diluted EPS. Adding the $876M of first-half 2026 items and the $293M of FY2025 Workforce Transformation severance (which the 10-K places in the fourth quarter of 2025) gives at least $11.729B, or $10.84 per share — a 16.35x trailing multiple. Add the $208M software impairment, if it fell in the second half of 2025, and it is $11.937B, $11.03, and 16.07x. We call trailing clean EPS "at least $10.84" and the honest trailing multiple "about 16.1-16.4x", against the GAAP 18.56x. It is a floor, not a point estimate, because the second-half-2025 UScellular merger-related costs sit in an Adjusted EBITDA reconciliation table that the extraction stripped.

The caveat we owe the reader, stated plainly. T-Mobile has been adjusting out "merger-related costs" continuously since the Sprint merger closed in April 2020 — Sprint through mid-2024, then Ka'ena, then UScellular, with UScellular costs running to the end of fiscal 2027 and "additional restructuring initiatives" still under evaluation. A company that has excluded integration costs for six consecutive years and expects to keep doing so for two more is arguably running integration as an ordinary operating expense. We present both the reported and the clean numbers and we do not pretend the clean one is free.

Gross margin — rejected outright

The vendor prints grossProfitMarginTTM of 54.5%, FY2025 gross margin of 47.6% and FY2024 of 63.6%. All three are artefacts and none is used in this dive. The reason is Section 8, finding 4: the vendor moves depreciation and amortisation between cost of revenue and operating expenses from period to period. Reconstructed on a consistent depreciation-excluded basis, FY2025 gross margin was 62.9% against FY2024's 63.6% — a 70 basis point decline, not a 1,600 basis point collapse. Even that reconstruction we present only as a check, not as a headline.

Costs, in the company's own words

For the June quarter: cost of services up $261M or 10% on wholesale network access costs paid to Metronet and Lumos plus UScellular; cost of equipment sales up $396M or 8% on "Higher average cost per device sold, primarily driven by an increase in the high-end phone mix"; selling, general and administrative up $437M or 8% on UScellular, "Higher bad debt expense" and retail-initiative contract terminations ($108M pre-tax charge in the quarter); depreciation and amortisation up $288M or 9%, and up $907M or 14% for the half, on UScellular assets, the 5G build and accelerated depreciation from cell-site decommissioning. Interest expense, net up $133M or 14% in the quarter. Effective tax rate 25.2% in the quarter against 24.7%, and 25.0% for the half against 23.9% — a rising tax rate is a headwind consensus has to absorb.

4. Balance sheet and the enterprise-value rebuild

This is the section where the vendor is most wrong, and by the largest absolute amount in this batch.

What the filings say

The 10-K, at 2025-12-31: "our total debt and financing lease liabilities were $88.6 billion, excluding our tower obligations, of which $81.1 billion was classified as long-term debt and $1.1 billion was classified as long-term financing lease liabilities."

The 10-Q, at 2026-06-30: "our total debt and financing lease liabilities were $86.9 billion, excluding our tower obligations, of which $78.5 billion was classified as long-term debt and $1.1 billion was classified as long-term financing lease liabilities." And: "As of June 30, 2026, our Cash and cash equivalents were $2.8 billion compared to $5.6 billion at December 31, 2025."

Correction 1 — the vendor's capitalLeaseObligations of $35.987B is NOT finance leases; it is operating leases, and it does not belong in total debt. The 10-K says financing lease liabilities were $1.1B long-term. The vendor's short-term plus long-term debt of $86.282B, plus roughly $2.3B of current financing lease liabilities, is the filing's $88.6B. The $35.987B block — $4.977B current, $31.010B non-current — is the operating lease liability, which the vendor has mislabelled and folded into debt. The vendor reports total debt of $122.269B; the 10-K shows $88.6B of debt and financing leases; we use the filing.

Correction 2 — the balance sheet is six months stale and the 10-Q supersedes it. Between 2025-12-31 and 2026-06-30 T-Mobile issued $6.4B of long-term debt net and redeemed or repaid $7.8B of aggregate principal, and cash fell from $5.6B to $2.8B. The vendor's most recent balance sheet is 2025-12-31; the filing gives 2026-06-30; we use 2026-06-30.

Correction 3 — shortTermInvestments: 0 is CORRECT here, and this is worth saying. The standard defect (net debt ignoring short-term investments) does not apply to T-Mobile. Its balance sheet carries no short-term investment line; longTermInvestments of $2.765B is the equity-method interest in the Lumos and Metronet joint ventures, which is not cash and is correctly excluded from net debt. We checked, and the vendor is right on this one field. The error is elsewhere.

The rebuild

> Market cap $190.088B

EV/EBITDA10.71x8.28x9.36x
Net debt/EBITDA4.00x2.54x3.62x
EV/Sales3.29x2.97x3.36x

The vendor overstates enterprise value by $29.07B, or 9.6%. That is the largest absolute EV error we have found in this batch, and it is what makes T-Mobile screen as a 10.7x-EBITDA levered telco when it is an 8.3x one.

We present both the operating-lease-excluded and operating-lease-included figures and we do not force a choice. Including capitalised operating leases in telecom enterprise value is a defensible convention; the ~$36B figure is a 2025-12-31 number and no June-2026 equivalent is available in this file. What is not defensible is calling them capital leases and burying them inside totalDebt without a label, which is what the vendor does.

Correction 4 — trailing EBITDA, rebuilt from the 10-Q

The vendor's ebitdaMarginTTM of 30.72% on trailing revenue of $92.189B implies EBITDA of $28.318B. Against trailing operating income of $18.713B, that implies depreciation and amortisation of only $9.605B — for a company whose FY2025 cash-flow statement reports $13.508B of D&A.

The 10-Q settles it arithmetically. It states D&A "increased $288 million, or 9%, for the three months ended and increased $907 million, or 14%, for the six months ended June 30, 2026." The vendor's own first-half-2025 D&A is $3.198B + $3.146B = $6.344B; +$907M gives first-half 2026 of $7.251B; less the vendor's June-quarter $3.434B (which matches the filing's +$288M exactly) leaves $3.817B for the March 2026 quarter. The vendor's depreciationAndAmortization field for that quarter reads $1.150B — and the vendor's own otherExpenses field for the same quarter reads $3.817B. The vendor contradicts itself; the filing gives $3.817B; we use $3.817B.

Corrected trailing D&A: $3.408B + $3.756B + $3.817B + $3.434B = $14.415B.

Corrected trailing EBITDA: operating income $18.713B + D&A $14.415B = $33.128B (35.9% of revenue).

The vendor understates trailing EBITDA by $4.81B, or 17.0%.

Debt structure, covenants and headroom — what the filings disclose

The largest asset, and where the vendor put it

Roughly $100.7B of the $219.237B balance sheet is spectrum licences — derived from the vendor's own intangiblesToTotalAssetsTTM of 53.92%, which implies $118.21B of goodwill and intangibles, less goodwill of $13.678B and other intangibles of $3.843B. The vendor's intangibleAssets field reports $3.843B for FY2025 and $103.070B for FY2024, having moved the spectrum block into otherNonCurrentAssets (which jumps from $4.252B to $107.705B) in FY2025 only. The vendor's own ratio field and its own balance-sheet field disagree by $100B; we use the ratio field's implication and state that the balance-sheet line-item series is not comparable year to year.

And spectrum is impairment-tested qualitatively. The 10-K: "For our assessment of Spectrum license impairment, we employed a qualitative approach. No events or change in circumstances have occurred that indicate the fair value of the Spectrum licenses may be below their carrying amount at December 31, 2025." A qualitative test on the single largest asset in the company means an impairment, if it ever comes, arrives as a step change. Goodwill was likewise tested qualitatively, with the Wireless reporting unit's fair value estimated "using a market approach, which is based on market capitalization"and market capitalisation has fallen 31.6% from the 52-week high since that test.

Equity is $59.203B against $219.237B of assets — 27.0%, with $30.545B of treasury stock. debtToEquityRatioTTM of 2.06x and priceToBookRatioTTM of 3.41x are arithmetically correct and economically thin, because equity is being deliberately consumed by buybacks. The vendor's own composite rating scores T-Mobile 1 out of 5 on debt-to-equity, dragging the overall grade to B / 3. We reject the debt-to-equity sub-score as a lens and use net debt to rebuilt EBITDA instead.

5. Cash flow and capital returns — and a free-cash-flow series that is not comparable

Fiscal yearOperating cash flowPP&E purchasesFCF (consistent basis)Vendor capitalExpenditureVendor FCFBuybackDividendsTotal returned

Two things in that table are traps and we walk the reader through both.

Trap one: the capex definition changes between years. In FY2022 and FY2025 the vendor's capitalExpenditure equals investmentsInPropertyPlantAndEquipment. In FY2023 and FY2024 it does not — it is $1.010B and $3.471B higher respectively, evidently including spectrum and intangible purchases. On the vendor's mixed basis, FY2025 free cash flow grew 80.3%. On a consistent property-and-equipment basis it grew 33.8%. Neither is right.

Trap two — and this is the one that matters: the 10-K says Adjusted Free Cash Flow grew SIX percent.

> "Adjusted Free Cash Flow increased $963 million, or 6%, for the year ended December 31, 2025."

And the reason for the divergence is disclosed in the same section:

> "Certain cash proceeds associated with the sale of receivables, which were recognized within investing cash flows before November 1, 2024, are recognized as operating cash flows. This change had no net impact to Adjusted Free Cash Flow."

That is the whole explanation. Operating cash flow rose $5.7B or 25% in FY2025 partly because receivable-sale proceeds moved into it from investing. The vendor's investing series corroborates: otherInvestingActivities was +$4.994B in FY2022 and +$3.979B in FY2023, then +$141M in FY2024 and −$4.129B in FY2025. The vendor reports free cash flow growing 80.3% in FY2025; the 10-K reports Adjusted Free Cash Flow growing 6%; we use the filing, and we do not use the vendor's multi-year free-cash-flow series to draw any trend conclusion.

The June 10-Q continues the pattern: "Adjusted Free Cash Flow increased $201 million, or 4%, for the three months ended and increased $404 million, or 4%, for the six months ended June 30, 2026." Four percent. Our arithmetic from those stated changes and (rounded) percentages implies roughly $5.2B in the June quarter and $10.5B in the half; because the percentages are rounded to whole numbers, those levels are approximate and are labelled as such.

First-half 2026 cash flows, verbatim from the 10-Q: operating cash flow up $883M or 6%; $5.3B of property and equipment purchases plus $510M of spectrum and intangible purchases; $7.8B of long-term debt repaid against $6.4B issued net; $7.1B of buybacks, $2.2B of dividends, $664M of financing lease repayments, $185M of tax withholding on share-based awards. Cash fell from $5.6B to $2.8B.

Capital returns — the swing factor, verified line by line

The dividend, and the vendor labelling trap the brief flagged. The vendor reports lastDividend: 3.94 and dividendPerShareTTM: 3.94, yielding 2.22%. That $3.94 is the trailing-twelve-month total, not the last declared quarterly dividend. The 10-Q gives the actual declarations:

> "On December 4, 2025, our Board of Directors declared a cash dividend of $1.02 per share... paid on March 12, 2026"

> "On March 19, 2026... a cash dividend of $1.02 per share... paid on June 11, 2026"

> "On June 15, 2026... a cash dividend of $1.02 per share, which will be paid on September 10, 2026"

Three quarters at $1.02 is $3.06; the trailing $3.94 implies the fourth quarter in the window was $0.88. The forward run-rate is $1.02 per quarter, $4.08 annualised — a 2.30% forward yield, not 2.22%. The dividend was raised roughly 16% between those two quarters.

The buyback, verbatim:

> "On December 11, 2025, we announced that our Board of Directors authorized our 2026 Stockholder Return Program of up to $14.6 billion... On April 23, 2026, we announced that our Board of Directors increased the 2026 Stockholder Return Program authorization to up to $18.2 billion."

> "During the three months ended June 30, 2026, we repurchased 11,420,845 shares at an average price per share of $188.76 for a total purchase price of $2.2 billion, and during the six months ended June 30, 2026, we repurchased 34,750,770 shares at an average price per share of $203.07 for a total purchase price of $7.1 billion."

> "Subsequent to June 30, 2026, from July 1, 2026, through July 17, 2026, we repurchased 2,149,600 shares at an average price per share of $182.53 for a total purchase price of $392 million... As of July 17, 2026, we had up to $8.5 billion remaining... through December 31, 2026."

Every tranche was bought above today's $177.21 — $203.07 for the half, $188.76 in the June quarter, $182.53 in July. That is a factual observation, not a criticism; it does mean the buyback has so far bought a falling stock.

The multi-year frame, also verbatim: "From January 1, 2026, through the end of 2027, the Company expects its business plan to support: Up to approximately $30.0 billion for share repurchases and cash dividends... and Over $22.0 billion in a discretionary and flexible envelope for opportunistic deployment, which may include de-levering, investments in our core business, strategic investments, and/or additional capital returns." This is management's own forward statement and is half-weighted accordingly.

Total shareholder yield, and whether free cash flow covers it

Amount% of $190.088B market cap
2026 authorised programme (buybacks and dividends)$18.2B9.57%
— of which dividends (4 × $1.02 × ~1.073B shares)~$4.38B2.30%
— implied buyback~$13.8B7.27%
First-half 2026 actual (buyback $7.1B + dividends $2.2B)$9.3B4.89% (9.79% annualised)

A 9.6% total shareholder yield is genuinely large and it is the strongest single argument for owning this stock.

But the coverage test the brief asked for does not pass cleanly. FY2025 free cash flow on the consistent basis was $17.995B; the 10-K's Adjusted Free Cash Flow is approximately $17.0B (our arithmetic from "increased $963 million, or 6%", and approximate because the percentage is rounded). Against $18.2B of intended returns, that is less than 1.0x coverage before a single dollar of strategic spending. And the strategic spending is committed:

Against that, one large inflow is pending: the Grain 800 MHz sale, $2.9B of cash consideration plus Grain's 600 MHz licences, FCC-approved 2026-07-01 and targeted to close in the third quarter of 2026, with "an increase to our cash income tax liability of approximately $850 million".

The honest conclusion: the 2026 capital return is funded by free cash flow plus asset sales plus a $2.8B cash balance that has already halved in six months. It is not fraudulent and it is not obviously unsustainable — the revolver is $10.0B and undrawn — but it is not self-funding either, and a reader should not treat a 9.6% shareholder yield on this balance sheet as equivalent to a 9.6% yield on an unlevered one.

6. Valuation — priced in or room?

At $177.21 (market cap $190.088B, approximately 1,072.7M shares, corrected enterprise value $274.19B):

Estimate coverage is good through 2028 — 13 to 18 analysts on the lines we use. The FY2029 EPS row rests on 11 analysts and FY2030 on FIVE; neither is used for any conclusion, and both carry an internal inconsistency (their netIncomeAvg divided by their epsAvg implies a share count of 1,131M, above the 1,013M implied for 2028 and above the 1,082M actually outstanding — the buyback simply stops in the model). Per the data contract, est.ebitdaAvg and est.ebitAvg are not used; we tested them and they fail — see Section 8, finding 8.

Basis note, and it is unusually clean here. The earn_cal actuals for the last three quarters — $1.88, $2.27, $2.99 — match inc_q GAAP diluted EPS exactly, and the FY2025 consensus of $9.895 landed 1.8% above the actual GAAP diluted $9.72. The estimate series is struck on a GAAP or near-GAAP basis, which is unusual and removes the GAAP-versus-adjusted ambiguity that distorts most large-cap forward multiples. All forward multiples in this dive are therefore GAAP-comparable, and the trailing multiple is shown on both the GAAP ($9.55, 18.56x) and clean (≥$10.84, ≤16.35x) bases.

Peer context. The vendor peer set is AMX ($74.7B), CMCSA ($88.5B), DIS ($170.5B), T ($160.2B), TDS ($3.8B), VIV ($19.7B) and VZ ($195.8B). Disney is not a comparable and is discarded. The relevant frame is that T-Mobile at $190.1B now sits BELOW Verizon at $195.8B for the first time in this file's history, and above AT&T at $160.2B. No peer earnings, multiples or estimates are supplied in the file, so no peer-multiple comparison is drawn — and we will not manufacture one from memory.

6a. What today's price assumes (the inversion)

At $177.21 — 12.75x the FY2027 consensus and 10.63x FY2028 — the price embeds the following falsifiable claims, each with a number and a date:

6b. The return bridge (why the multiple moves)

Expected return over the next twelve months decomposes as: EPS growth (+27.4%, from FY2026E $10.904 to FY2027E $13.896) + multiple drift + dividend yield (+2.30%).

We are going to be pedantic about the multiple, because the guardrail matters here more than anywhere else in this batch. Today the market pays 12.75x the FY2027 estimate. In twelve months' time the forward year is FY2028. If the market then pays the same 12.75x on FY2028E of $16.669, the price is $212.6 — up 19.9% with no re-rating whatsoever. That is a rolldown outcome, not an expansion outcome, and we are not going to dress it up as one.

Our base of $208 is therefore, deliberately, slightly BELOW a constant-forward-multiple roll-forward. Expressed two ways, both disclosed:

Both statements are true and they describe different clocks. The first is the honest one for a twelve-month horizon, and it is why our base assumes NO multiple expansion. Essentially all of the expected return is earnings growth plus the dividend.

The bull case at $259 likewise requires no re-rating at all — it holds the same 12.5x and applies it to the FY2028 consensus high of $20.684. That is deliberately conservative construction: the bull case is an earnings outcome, not a valuation outcome. The bear case at $131 is the only one that needs a de-rating, and it needs two things at once: the FY2028 consensus low of $14.606 and a compression to 9.0x. Say that plainly: on this name the upside does not need the crowd to change its mind, and the downside does. That asymmetry is the single most attractive feature of the setup, and it is why a stock this broken is a Watch rather than an Avoid.

6c. Variant perception (where we differ, what would surprise)

Synthos fair values

All three anchors are multiples of the FY2028 consensus EPS distribution (mean $16.669, low $14.606, high $20.684, 13 analysts), cross-checked against FY2027E of $13.896 (17 analysts).

Base is 17.4% above spot; asymmetry roughly 1.77:1 to the upside (26.1% down, 46.2% up). That is a better ratio than the KLAC setup in this batch and a better one than most names carry at these prices. What makes it a Watch rather than a Buy is that our base sits 11.7% BELOW the street, the knowledge base is empty, the chart is below both moving averages with RSI at 42 — weak but not oversold, so there is no exhaustion signal — and there is no company-specific event for 79 days. We want this exposure. We do not want it into a downtrend with consensus targets still 12% above our own number.

7. Knowledge base — three claims, none about the equity, and three collisions inside a word

Raw hits: 6. Entity matches: 3. Text-only matches: 3. Used as supporting colour: 3. Used as name-level conviction: 0. Discarded for collision: 3.

The primary search covered TMUS, T-Mobile and TMobile across all 51,928 distilled claims. Supplementary sweeps on Mike Sievert, Sievert, Deutsche Telekom, UScellular, Metro by T-Mobile, Gopalan, fixed wireless and wireless carrier returned ZERO hits each — eight separate sweeps, nothing. Broad sector sweeps returned 5G: 59 text-only, 0 entity; telecom: 1 entity + 45 text-only; broadband: 1 entity + 14 text-only; Verizon: 1 entity + 4 text-only; AT&T: 6 entity + 6 text-only.

The three text-only "matches" on the ticker are pure homograph collisions and the mechanism is worth stating because it will recur. The search string TMUS is contained inside the word LITMUS. All three hits are sentences containing the phrase "litmus test" — one about Brazilian pension reform in 2019, one about US construction data in 2024, and one about a technology merger as a test of the deal environment in 2025. None mentions T-Mobile, telecommunications or wireless in any form. All three are discarded in full.

The sector sweeps are also discarded, for the reason the brief anticipated. Of the 59 "5G" text-only hits, none names T-Mobile; the top hit is a China-technology claim. The single "telecom" entity match is a 2020 Canadian-banks-and-REITs basket. The single "broadband" entity match is about Liberty Broadband's stake in Charter. Generic 5G, wireless and telecom claims are sector colour and are not admitted as name-level conviction. Of the six AT&T entity matches, none names T-Mobile — a claim about a competitor is not a claim about this company, and they are excluded on that ground.

That leaves three genuine entity matches. Here they are, verbatim.

> 2025-09-10 · bullish · conviction 55 · horizon: thesis · entities: Starlink, Verizon, AT&T, T-Mobile · channel: all_in · NO NAMED SPEAKER

> "Starlink could become a comprehensive global carrier (home Wi-Fi + direct-to-cell), though existing carriers won't be put out of business."

> 2025-03-18 · bullish · conviction 78 · horizon: thesis · entities: NVIDIA, Cisco, T-Mobile · channel: jensen_huang · NO NAMED SPEAKER

> "Nvidia/Cisco/T-Mobile will build a US radio-network stack; AI-RAN will accelerate the ~$100B/yr telecom capex market."

> 2026-03-16 · bullish · conviction 65 · horizon: thesis · entities: Nokia, T-Mobile · channel: jensen_huang · NO NAMED SPEAKER

> "The ~$2T telecom base-station infrastructure will be completely reinvented as AI infrastructure running AI at the edge (Aerial/AI-RAN)."

What this lane is, stated without inflation.

All three are entity matches, so T-Mobile genuinely appears in each entity list. Not one is a claim about T-Mobile as a security.

All three carry speaker: null and are attributed only to a channel. Under the 4-lane attribution policy that is the weakest form of sourcing we accept — a channel-level attribution tells you where a claim was said, not who said it or what their record is. No claim in the lane carries a management speaker_role, so the half-weight management discount does not apply; but two of the three carry the supplier's-management problem, which is functionally the same discount applied to a different company's executive.

Two adjacent claims are worth a single sentence each as colour, clearly labelled as NOT about T-Mobile. A 2023-03-13 claim (channel real_vision, no named speaker, entities Reliance Industries, Starlink, Huawei, AT&T) argues that "Base-infrastructure layer (5G/6G, Starlink) is going exponential; indebted telcos can't build, so Starlink owns data from space outside sovereign control"a bearish structural claim about levered carriers that describes T-Mobile's category without naming it. And a 2025-03-13 claim (channel raoul_pal, no named speaker, entities Straight Path, AT&T) argues that "Wireless spectrum has consistently appreciated; bought at auction and held, it has delivered double-digit annualized returns"relevant to the ~$100.7B of spectrum on this balance sheet, and the only independent corroboration in the file for the qualitative impairment test. Neither names T-Mobile; neither is admitted to the conviction pool; both are reported because a reader deserves to know they exist.

Conclusion, stated as a finding rather than dressed up. The Synthos knowledge base has no view on T-Mobile US, Inc. It has one satellite-disruption claim in which T-Mobile is an object rather than a subject, and two supplier-sourced capital-expenditure claims. None is name-level conviction, none justifies a conviction premium or discount in the fair value, and the absence — across eight zero-hit targeted sweeps including the current and former chief executive, the controlling shareholder and the largest acquisition — is itself the finding. Conviction rating Low, breadth 3, net conviction none, and the emptiness of the lane is a direct input to the Watch verdict.

8. Data integrity — what we rejected from the vendor file and why

Fourteen findings. Listed rather than silently corrected. T-Mobile is, on balance, one of the WORST vendor files in this batch on the balance sheet and cash flow, and one of the cleanest on revenue disaggregation. Both facts are stated.

1. bal_a is SIX MONTHS STALE and the 10-Q supersedes it — the largest single correction in this dive. The most recent balance sheet in the payload is 2025-12-31. The 10-Q filed 2026-07-23 gives 2026-06-30, during which T-Mobile issued $6.4B of long-term debt net, repaid $7.8B of aggregate principal, and let cash fall from $5.6B to $2.8B. The vendor's balance sheet is dated 2025-12-31; the filing gives 2026-06-30; we use 2026-06-30 throughout. We also scanned all three 8-Ks specifically for a financing that post-dates every statement in the file, per the defect-class-1 protocol. There is none — the three 8-Ks are an annual meeting, a set of management changes and an earnings furnishing. That check was run and it came back clean; the staleness problem here is ordinary lag, not a missed deal.

2. capitalLeaseObligations of $35.987B is the OPERATING lease liability, mislabelled and folded into totalDebt — REJECTED. The 10-K states financing lease liabilities of $1.1B long-term at 2025-12-31 and total debt and financing leases of $88.6B; the 10-Q states $1.1B and $86.9B at 2026-06-30. The vendor's $35.987B block ($4.977B current, $31.010B non-current) cannot be finance leases. The vendor reports total debt of $122.269B and net debt of $116.671B; the 10-Q shows $86.9B of debt and financing leases against $2.8B of cash, or $84.1B net; we use $84.1B. Consequential rejections: enterpriseValueTTM ($303.263B → $274.19B), netDebtToEBITDATTM (4.00x → 2.54x), evToSalesTTM (3.29x → 2.97x), evToEBITDATTM/enterpriseValueMultipleTTM (10.71x → 8.28x), evToOperatingCashFlowTTM (10.52x), evToFreeCashFlowTTM (19.16x). We also present the operating-lease-INCLUSIVE figures (EV $310.2B, 9.36x, 3.62x) because that convention is defensible in telecom; what is not defensible is the label.

3. Trailing EBITDA is understated by 17.0% because ONE quarter's depreciation figure is wrong — REJECTED and rebuilt. ebitdaMarginTTM of 30.72% implies trailing EBITDA of $28.318B, which against trailing operating income of $18.713B implies D&A of $9.605B for a company reporting $13.508B in FY2025. The 10-Q's stated first-half D&A increase of "$907 million, or 14%" on the vendor's own first-half-2025 base of $6.344B implies first-half-2026 D&A of $7.251B; less the June quarter's $3.434B (which matches the filing's stated +$288M exactly) leaves $3.817B for the March 2026 quarter — against the vendor's depreciationAndAmortization field of $1.150B and the vendor's own otherExpenses field of $3.817B for the same quarter. The vendor contradicts itself; we use $3.817B. Rebuilt trailing EBITDA = operating income $18.713B + D&A $14.415B = $33.128B (35.9% margin), and every EV/EBITDA figure in this dive is computed on it.

4. Gross profit and gross margin are NOT comparable across periods — REJECTED ENTIRELY, in every period. The vendor moves depreciation and amortisation between costOfRevenue and operatingExpenses from quarter to quarter and from year to year. Annually: FY2025 costOfRevenue is $46.241B (D&A inside) against FY2024's $29.653B (D&A in otherExpenses), manufacturing a fall in gross margin from 63.6% to 47.6% that did not happen. Quarterly, the same field reads $7.400B, $7.376B, $11.134B, $13.996B, $8.827B, $8.030B across the last six quarters — a gross margin swinging between 42% and 65%. On a consistent depreciation-excluded basis FY2025 gross margin was 62.9% against FY2024's 63.6%. No gross-margin figure from this vendor file appears as a headline anywhere in this dive.

5. The free-cash-flow series is not comparable across years, and the filing contradicts it outright. capitalExpenditure equals investmentsInPropertyPlantAndEquipment in FY2022 and FY2025 but exceeds it by $1.010B in FY2023 and $3.471B in FY2024. On the vendor's mixed basis FY2025 free cash flow grew 80.3%; on a consistent basis 33.8%; and the 10-K says "Adjusted Free Cash Flow increased $963 million, or 6%." The 10-K explains the divergence itself: "Certain cash proceeds associated with the sale of receivables, which were recognized within investing cash flows before November 1, 2024, are recognized as operating cash flows." The vendor's own otherInvestingActivities corroborates — +$4.994B (FY2022), +$3.979B (FY2023), +$141M (FY2024), −$4.129B (FY2025). The vendor implies 80% free-cash-flow growth; the filing says 6%; we use the filing and draw no trend conclusion from the vendor series.

6. lastDividend: 3.94 and dividendPerShareTTM: 3.94 are the TTM total, not the last declared dividend — corrected from the filings. The 10-Q records quarterly cash dividends of $1.02 per share declared 2025-12-04, 2026-03-19 and 2026-06-15. Three at $1.02 plus one at $0.88 is $3.94 — the vendor's figure, correctly computed but mislabelled. The forward run-rate is $4.08, a 2.30% yield, not 2.22%. dividendPayoutRatioTTM of 41.1% is computed on the trailing figure and is likewise a lagging number.

7. seg_prod is the revenue-DISAGGREGATION table, not the segment table — and here the distinction is definitive, because there IS no multi-line segment table. The 10-K, Note 1: "We operate as a single operating segment." The 10-Q's Note 11 – Segment Reporting presents "our Wireless segment", singular. The five seg_prod lines are the Note 11 revenue disaggregation from Revenue from Contracts with Customers. We verified the sums: FY2025 $88,309M, FY2024 $81,400M, FY2023 $78,558M and FY2022 $79,571M — all four EXACTLY equal to reported revenue, to the dollar — and every line change matches the 10-K MD&A's stated deltas and percentages. This is a clean field, used, correctly labelled.

8. The FY2021 seg_prod row does not sum — DISCARDED. Five lines total $77.795B against reported FY2021 revenue of $80.118B, short by $2.323B (2.9%). The FY2020 and FY2019 rows contain a sixth line, "Roaming and Other Service Revenue" ($2.078B in FY2020), absent from FY2021. The FY2021 row is incomplete and no conclusion in this dive touches it.

9. est.ebitAvg and est.ebitdaAvg are unreliable — TESTED against actuals, then NOT USED. The FY2025 ebitAvg of $13.607B is 27.4% BELOW the actual operating income of $18.744B; the FY2025 ebitdaAvg of $28.604B is 11.3% below our computed FY2025 EBITDA of $32.252B (operating income $18.744B + D&A $13.508B). Neither trips the standard detection signatures — ebitdaAvg exceeds ebitAvg in every year and neither is negative — so this file would pass the automated screen while still being wrong by a quarter. All forward valuation in this dive runs on epsAvg and revenueAvg.

10. The FY2029 and FY2030 estimate rows are internally inconsistent — EXCLUDED from every conclusion. netIncomeAvg ÷ epsAvg implies a share count of 1,131M in both 2029 and 2030, against 1,013M implied for 2028, 1,063M for 2027 and an actual 1,082.4M diluted in the June 2026 quarter. The model has the buyback stopping and the share count rising 12% — which is the opposite of the $18.2B programme actually running. Coverage is also thin: 11 analysts on FY2029 EPS and FIVE on FY2030. Both rows are reported for completeness and used for nothing.

11. intangibleAssets collapses from $103.070B to $3.843B between FY2024 and FY2025 while otherNonCurrentAssets rises from $4.252B to $107.705B — the year-on-year asset-composition comparison is REJECTED. T-Mobile did not dispose of $99B of spectrum; the vendor reclassified it into "other". The vendor's own intangiblesToTotalAssetsTTM of 53.92% implies $118.21B of goodwill and intangibles, of which roughly $100.7B is spectrum licences — and that ratio field is right while the balance-sheet field is wrong. We use the ratio field's implication and state that the line-item series is not comparable.

12. earn_cal and inc_q disagree on the September 2025 quarter — flagged, and inc_q used. The earnings calendar reports epsActual of $2.59 for the 2025-10-23 report; inc_q reports diluted EPS of $2.41 for the quarter ended 2025-09-30 ($2.714B net income ÷ 1,126.6M diluted shares = $2.409, internally consistent). The other five entries agree exactly — 2025-07-23 $2.84, 2026-02-11 $1.88, 2026-04-28 $2.27, 2026-07-23 $2.99 — all matching inc_q GAAP diluted EPS to the cent. We use $2.41 for the trailing-twelve-month calculation, giving trailing diluted EPS of $9.55 and a P/E of 18.56x, which is what the vendor's own priceToEarningsDilutedRatioTTM of 18.556 independently confirms. Using $2.59 would give $9.73 and 18.21x; the difference is not material to any conclusion, and the discrepancy is reported rather than resolved.

13. quote.yearHigh/yearLow disagree with tech.hi52/lo52 — we use tech and say so. The quote block reports a 52-week high of $261.56 and low of $165.66; the computed technical block reports $259.01 and $167.73. The discrepancies are 1.0% and 1.2%. We use the tech figures throughout, because they are computed from the same six-year close series that produces the moving averages, drawdown and relative-return figures. Note also that max_dd_from_peak of −35.05% exceeds pct_from_hi of −31.58%, implying a six-year peak of approximately $272.83 above the 52-week high of $259.01. Per the data contract that is NOT a defect and it is not reported as one.

14. Null and zero fields scanned; three found and explained. researchAndDevelopmentExpenses reads $0 for FY2020-FY2024 and $278M for FY2025 — T-Mobile does not disclose research and development as an income-statement line, so the FY2025 figure is a mapping artefact and the series carries no information; it is not used. generalAndAdministrativeExpenses and sellingAndMarketingExpenses read $0 for FY2021-FY2023 with only the combined SG&A populated, then split from FY2024 — the expense-composition series is not comparable and is not used. shortTermInvestments reads $0 in all three years and that is CORRECT (see Section 4, correction 3). seg_geo is an empty array — no geographic disaggregation is supplied at all, which is stated as a gap rather than estimated around.

Not defects, correctly reported and independently confirmed:

Share-count cross-check — run because the price level and the buyback demanded it, and it PASSES. Market capitalisation of $190,088,136,540 ÷ $177.21 implies 1,072.7M shares. Weighted-average diluted shares in the June quarter were 1,082.4M, and the ratios_ttm per-share fields imply 1,081.8M. The 0.9% gap between the market-cap count and the June-quarter diluted average is exactly what a live buyback produces: the company repurchased 11.42M shares during the quarter and a further 2.15M between 1 and 17 July, so a point-in-time count below the quarter's weighted average is arithmetically necessary. There is no share-class problem — there is a single class of common stock, par $0.00001, with 100 million authorised preferred shares and NONE outstanding at 2026-06-30. The one thing we could not verify directly: the 10-Q cover page's share count sits in a table the extraction stripped, so the cover-page figure is unavailable and we say so rather than implying we read it.

Non-equity tripwire — checked, one warning sign triggered, resolved. Beta is 0.319 — only marginally above the sub-0.3 threshold the tripwire flags, and on a name with a 2.30% dividend that deserves an explicit answer. It is common equity: the price of $177.21 is not par-like ($25, $50 or $1,000); the dividend is variable and was RAISED from $0.88 to $1.02 per quarter inside the trailing twelve months, which a fixed-rate instrument cannot do; the 52-week band of $167.73 to $259.01 is a 54% range, the opposite of the narrow band a fixed-income-like instrument shows; the 12-month price return is −25.3%, far outside any bond-like envelope; volume was 5,218,755 shares (roughly $925M of turnover); and the security is NASDAQ-listed common stock, par value $0.00001 per share, per the 8-K cover pages. The 0.319 beta is a genuine low-beta defensive-telecom characteristic, not an instrument-type error. This is common equity.

9. Technicals

Today's move and what it does to the entry

TMUS closed 2026-08-04 at $177.21, up $0.12 or 0.07% from a previous close of $177.09. It opened at $175.22, traded a $174.20 to $177.33 range, and closed within 0.07% of the day's high on 5,218,755 shares against a 5,475,454 average. This was, functionally, an unchanged day on below-average volume.

And the context matters more than the move. 2026-08-04 was a violent sector-wide semiconductor rally — MRVL +12.8%, INTC +10.9%, LRCX +7.9%, MU +7.6%, KLAC +7.0%, AMD +7.0%, AMAT +5.5%, ASML +4.2%. T-Mobile participated in none of it, which is exactly what a 0.319-beta defensive telecommunications stock does on a risk-on day, and is itself a small piece of evidence that the instrument is behaving as advertised. No company-specific news appears in this file for 2026-08-04; the last company event was the 2026-07-23 earnings release, twelve days earlier.

The honest read on the entry, and it inverts the usual problem in this batch. Everywhere else in these twelve names the question is whether the reader is being asked to pay up for a one-day gap. Here there is no gap to pay for. The entry price is not distorted by a single session; it is the settled level after a twelve-month, 31.6% de-rating.

So the question is not "am I paying up today?" It is "has the selling stopped?" And the chart says no.

What we are therefore telling the reader, plainly: the valuation case is good enough to want this and the chart is bad enough to wait for it. The two setups that would change it are the falsifiers:

Buying today means catching a name that has lost 49 points to the index in twelve months, with no company catalyst for 79 days, and with a consensus target 12% above our own fair value that has not yet been marked down. That is not a trade with an edge in it — but it is a name worth a standing bid below.

10. Insiders — eight transactions, seven of them the annual director grant, and zero conviction either way

Mark Wolfe NelsonChief Legal Officer & General CounselA-Award97.52$187.022026-06-1165,967.312

The reading, stated carefully. Every one of the eight transactions is coded A-Award — an acquisition by grant, not a purchase. Seven are the standard annual director equity award of 1,384 shares each, all dated 2026-06-16, which is the date of the annual meeting recorded in the 8-K filed 2026-06-18. That is a scheduled, formulaic, board-compensation event and carries no information. The eighth, 97.52 shares to the Chief Legal Officer at $187.02 on 2026-06-11, is a fractional accrual consistent with a dividend-equivalent or deferral credit, not a discretionary act.

What the file contains is therefore: ZERO open-market purchases and ZERO open-market sales. That is a neutral signal and it is reported as neutral.

Two observations are worth making anyway.

First, and mildly negative: nobody stepped in. The stock fell 31.6% from its high over this window and not one officer or director made a discretionary open-market purchase in the eight most recent filings. Discretionary buying into a drawdown is the single highest-information insider signal available, and its absence in a drawdown this deep is a small mark against.

Second, the residual holdings are asymmetric. Director Raul Marcelo Claure holds 1,849,801 shares — $327.8M at the closing price, an order of magnitude above every other named insider and above most of the executive team. Chief Legal Officer Mark Nelson holds 65,967. Several directors hold between 2,000 and 8,000 shares — less than $1.5M each, and in two cases under $500,000. A board with that little economic exposure to a controlled company in which the controlling shareholder holds 56.9% of the voting power is a governance observation, and we make it without drawing a conclusion from it.

Note the file contains no transactions from the chief executive or chief financial officer at all in the eight most recent records.

11. Verdict, kill-criteria and flip conditions

Watch.

This is the worst chart in the batch and the most-corrected balance sheet, and those two facts pull in opposite directions.

What has genuinely deteriorated, and none of it is in dispute: T-Mobile stopped reporting postpaid phone net customer additions beginning with the March 2026 quarter, and that number is present throughout the FY2025 10-K; postpaid net account additions fell 41,000, or 13%, in the June quarter; postpaid account churn rose 7 basis points in the quarter and 9 in the half, with "Higher industry switching" named as a cause; prepaid revenue fell 6%; wholesale and other service revenue fell 8%; reported first-half net income fell 7.0%; and the revenue growth that remains was bought — UScellular contributed 3,287,000 postpaid phone customers on 2025-08-01, Metronet 755,000 fibre customers, Lumos 97,000. Consensus has revenue growth decelerating to 4.4% next year and 3.3% by 2030. The premium multiple this company carried was underwritten by a published growth number that is no longer published, and a 31.6% de-rating and a 49-point twelve-month loss to the S&P is a proportionate response to that.

What is materially better than any screen shows, and this is why the name is a Watch and not an Avoid:

What we are declining to pay for today: a base fair value of $208 that sits 11.7% BELOW the street's $235.50, on a name where 44 of 54 analysts still carry a buy; a chart below both moving averages with MACD negative and RSI at 42 — weak but not oversold, so there is no floor signal; 79 days with no company-specific catalyst; a knowledge-base lane of three claims, none about the equity, two from a supplier's chief executive and three discarded as collisions inside the word "litmus"; zero discretionary insider buying into a one-third drawdown; and a capital-return programme that is not covered by free cash flow once $5.0B to $7.2B of committed strategic outflows are counted.

The distinction that matters, and it answers the question the brief posed directly. The growth story HAS ended — the disclosure change proves it and the account and churn data confirm it. That is our answer and we are not hedging it. But the price has already fallen 31.6%, the multiple is 12.75x forward against a 9.6% shareholder yield, and the reported earnings decline that is driving the de-rating is a disclosed, itemised, end-dated integration cost sitting on top of clean earnings that grew 8.6%. A serious opportunity and a dead growth story are not mutually exclusive; that combination is precisely what a value name is. In the Synthos frame, a name where our fair value sits 11.7% below consensus, the conviction lane is empty and the trend is still down is a Watch by construction — we want the exposure, at a level, after the selling stops.

Pre-registered KILL criteria — what would take this to Avoid:

Pre-registered FLIP conditions — what would take this to Buy — Tactical:

Where TMUS fits in the Synthos Framework Portfolio. The defensive-connectivity / high-shareholder-yield sleeve, at 0% today with a 2-3% target on a confirmed base near $168-172 or a clean October print. On the batch-overlap question: T-Mobile has almost no correlation with the semiconductor complex that dominates this batch — beta 0.319, a completely inert session on a day the semis moved 5-13%, and a 12-month return 49 points behind the index. That is genuine diversification rather than diversification dressed as concentration, and it is the strongest structural argument for eventually owning this name. Logged as a tracked Synthos call (Watch) as of 2026-08-04 at $177.21.

Single biggest risk: that the deceleration is structural and consensus 2027 EPS of $13.896 is wrong. Revenue is growing 4%. The EPS line needs 400 to 500 basis points of net-margin expansion and an 8.8% share-count reduction to reach $16.669 by 2028. The buyback leg is funded and near-certain. The margin leg is not: it requires integration costs to end on schedule while the effective tax rate is rising (25.0% for the half against 23.9%) and interest expense is rising (up 13% for the half on a 4.2% average rate against 4.1%). If the margin leg delivers only half, FY2028 EPS is nearer $14.60 than $16.67, and at 12.5x that is $183 — 3% above today's price. The forward multiple looks cheap because the E in it is doing a great deal of work.

Most fragile assumption in the price: that the subscriber deterioration stops getting worse. Nothing in a 12.75x multiple requires reacceleration — which is why the stock is not expensive. But it does require the bleeding to stop, and the company has just removed the metric that would let a reader check. Postpaid net account additions fell 13%, account churn rose 7 basis points, and the filing names "higher industry switching" and "higher average broadband-only accounts" — a competitive cause and a strategic one, both of which point at the next quarter as well as this one. We can no longer see postpaid phone net additions. Until the account-level numbers stabilise, we are being asked to underwrite a trend we cannot fully observe, and that is the reason this is a Watch.
